                                    Part I
 
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, packaging 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 30 through 32 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 addition to specific products, PPG supplies technical
expertise, engineering and purchasing services to the automotive original and
industrial portions of the business. In the automotive original and industrial
portions of the coatings business, PPG sells directly to a variety of
manufacturing companies. The packaging portion of the coatings business
supplies finishes for aerosol, food and beverage consumer products. 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, PPG-operated outlets 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
1998. In February 1998, PPG acquired the German automotive coatings business
of Helios-Lacke Bollig & Kemper GmbH & Co. KG; in September 1998, PPG acquired
the technical coatings business in Australia and New Zealand of Orica Ltd.,
which included the automotive refinish, automotive original equipment, coil,
packaging and industrial coatings businesses; in November 1998, PPG acquired
the U.S. architectural coatings business of Courtaulds plc (Courtaulds) held
by Akzo Nobel N.V. (Akzo); and in December 1998, PPG acquired a portion of the
global packaging coatings business of Courtaulds from Akzo, with substantially
all of the remainder acquired by PPG in early 1999. In August 1998, PPG
divested the European decorative coatings business of Max Meyer Duco S.p.A.
 
The principal production facilities of the coatings business are concentrated
in North America and Europe. North American production facilities consist of
18 plants in the United States, two in Canada and one in 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 four plants each in Italy and
Germany, three plants in Spain, two plants in the People's Republic of China,
and one plant each in Brazil, England, France, Netherlands, Australia, Turkey
and Portugal. PPG owns equity interests in operations in India, South Korea
and Taiwan. Additionally, the coatings business operates 10 service centers in
the United States, two each in Canada and Mexico, and one each in Poland and
Argentina to provide just-in-time delivery and service to selected automotive
assembly plants. Nineteen training centers in the United States, 15 in Europe,
10 in Asia, two in South America and one each in Mexico and 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
 
                                       1
<PAGE>
 
of persons employed by the coatings segment during 1998 was 12,000.
 
In 1998, PPG approved a restructuring plan associated with cost reduction
initiatives which resulted in a pre-tax charge of $9 million in our coatings
operations.
 
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.
 
In January 1998, PPG acquired the assets of an automotive glass plant in
Evart, Mich. PPG divested its European flat and automotive glass operations in
July 1998, resulting in a pre-tax gain of $85 million.
 
PPG's principal glass production facilities are concentrated in North America
and Europe. Fifteen plants operate in the United States, of which six produce
automotive glass products, five produce flat glass, 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. One
plant operates in Italy producing aircraft transparencies. One plant each in
England and the Netherlands produce fiber glass. PPG owns equity interests in
operations in Denmark, 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 manufacturing and just-in-time service to selected
automotive customer locations, and one coating facility for flat glass products.
The average number of persons employed by the glass segment during 1998 was
14,700.
 
During 1998, PPG approved a restructuring program, which included cost
reduction initiatives in our glass operations, and recorded a pre-tax charge
of $9 million. PPG also recorded additional pre-tax charges in 1998 related to
a 1997 restructuring program, including a $15 million pre-tax charge related
to the disposition of the Company's equity interests in two Asian float glass
plants and two Asian downstream fabrication facilities and the reversal of a
$3 million reserve related to the closure of the Perry, Ga., flat glass plant.
 
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(Registered
Trademark) lenses; optical monomers; precipitated silicas for tire, shoe, and
battery separator businesses and phosgene derivatives and other intermediates
for the pharmaceutical, agricultural and fuel additives businesses.
 
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 each in Canada and
Mexico. The two largest facilities, located in Lake Charles, La., and Natrium,
W. Va., primarily produce chlor-alkali products. 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 1998 was 4,800.
 
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 and other resins in the coatings segment; sand, soda ash, energy and
polyvinyl butyral 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 PPG's significant raw material requirements, there is more than one source
of supply or alternative raw materials.
 
Research and Development
 
Research and development costs, including depreciation of research facilities,
during 1998, 1997 and 1996 were $287 million, $266 million and $255 million,
respectively.
 
                                       2
<PAGE>
 
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 $18 million in 1998 and $25 million in each of
the years 1997 and 1996 from royalties and the sale of technical know-how.
 
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
that of domestic operations.
 
Employees
 
The average number of persons employed worldwide by PPG during 1998 was
32,500.
 
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 $19 million, $32 million and $18 million
in 1998, 1997 and 1996, respectively. It is expected that expenditures for
such projects in 1999 will approximate $35 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 54 cleanup
sites, including 32 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 December 31, 1998 and 1997, PPG had
reserves for environmental contingencies totaling $94 million and $100
million, respectively. Pre-tax charges against income for environmental
remediation costs totaled $10 million in 1998, $34 million in 1997 and $27
million in 1996.
 
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 damages are sought. These lawsuits and claims relate to product
liability, contract, patent, environmental, antitrust 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
 
                                       3
<PAGE>
 
parties with respect to actual and contingent losses related to environmental
matters. Included among PPG's legal proceedings are the following:
 
The Company has been named as a defendant in a number of antitrust lawsuits
filed in federal and state courts by various plaintiffs. These suits allege
PPG was involved with competitors in fixing prices and allocating markets for
certain glass products. Twenty-eight cases were filed in federal courts, all
of which have been consolidated in a single federal district court (W.D. Pa.)
for pretrial proceedings under the multidistrict litigation rules. Ten cases
were filed in state courts in California, Wisconsin and Tennessee; the
Wisconsin case was removed to federal court and then consolidated under
multidistrict litigation. Among the defendants in these actions are Pilkington
plc; Libbey-Owens Ford Co., Inc.; AFG Industries; Asahi Glass Co., Ltd.;
Guardian Industries Corp., and Ford Motor Company. These lawsuits purport to
be class action suits. The plaintiffs in these cases are seeking economic and
treble damages and injunctive relief.
 
Securities Exchange Commission rules require the Company to report any
environmental proceeding involving a potential fine exceeding $100,000. For
that reason, PPG's Form 10-Q for the quarter ended September 30, 1998 reported
that the Company received a Notification of Potential Enforcement Action from
the United States Environmental Protection Agency (EPA) which alleged that the
Company's Torrance facility failed to timely submit a certain report for 1995.
On January 12, 1999, that matter was settled and a Consent Agreement and
Consent Order was entered by the EPA under which PPG agreed to pay a civil
penalty of $21,148 and perform a supplemental environmental project to improve
solvent recovery at the Torrance facility.
 
Management believes that, in the aggregate, the outcome of all lawsuits and
claims involving PPG will not have a material effect on PPG's consolidated
financial position, results of operations, or liquidity.

Item 5. Market for the Registrant's Common Equity and Related
 Stockholder Matters
Stock Exchange Listings...............................................    45
Quarterly Stock Information...........................................    45
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 Exhibits 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 1998, the
Directors, as a group, were credited with 6,674 Common Stock
Equivalents under this plan. The values of the Common Stock
Equivalents, when credited, ranged from $51.00 to $72.88.

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 1998, the Directors, as a group, received 2,582
Common Stock Equivalents under this plan. The values of those Common
Stock Equivalents, when credited, ranged from $52.50 to $70.94.

            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, 1998 and
            1997, and the related statements of income,
            comprehensive income, shareholders' equity and cash
            flows for each of the three years in the period ended
            December 31, 1998, and have issued our report thereon
            dated January 21, 1999; such financial statements and
            report are included in your 1998 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, 1998, 1997 and 1996.
            The financial statement schedule is the
            responsibility of the Company's management. Our

                                   ---------


     Statement with respect to Series A Junior Participating Preferred Stock, 
being the first series of Preferred Stock, without par value, of PPG Industries,
Inc.

     RESOLVED, that this Board of Directors, pursuant to authority expressly 
vested on it by the provisions of the Articles of Incorporation of PPG 
Industries, Inc. (hereinafter called the "Corporation") hereby authorizes the 
issue of the first series of Preferred Stock, without par value, of the 
Corporation and hereby fixes the designation and relative rights and preferences
thereof in addition to those set forth in said Articles of Incorporation, as 
follows:

     Section 1.  Designation and Amount.  The shares of such series shall be 
                 ----------------------
designated as "Series A Junior Participating Preferred Stock" (the "Series A
Preferred Stock") and the number of shares constituting the Series A Preferred 
Stock shall be 2,000,000. Such number of shares may be increased or decreased by
resolution of the Board of Directors; provided, that no decrease shall reduce
                                      --------
the number of shares of Series A Peferred Stock to a number less than the number
of shares then outstanding plus the number of shares reseved for issuance upon
the exercise of outstanding options, rights or warrants or upon the conversion
of any outstanding securities issued by the Corporation convertible into Series
A Preferred Stock.

     Section 2.  Dividends and Distributions. 
                 ---------------------------

                 (A) Subject to the rights of the holders of any shares of any 
series of Preferred Stock (or any similar stock) ranking prior and superior to 
the Series A Preferred Stock with respect to dividends, the holders of shares of
Series A Preferred Stock, in preference to the holders of Common Stock, par 
value $1.66-2/3 per shares (the "Common Stock"), of the Corporation, and of any 
other junior stock, shall be entitled to receive, when, as and if declared by 
the Board of Directors out of funds legally available for the purpose, quarterly
dividends payable in cash on the first day of March, June, September and 
December in each year (each such date being referred to herein as a "Quarterly 
Dividend Payment Date"), commencing on the first Quarterly Dividend Payment Date
after the first issuance of a share or fraction of a share of Series A 
Preferred Stock, in an amount per share (rounded to the nearest cent)

<PAGE>
equal to the greater of (a) $1 or (b) subject to the provision for adjustment
hereinafter set forth, 100 times the aggregate per share amount of all cash
dividends, and 100 times the aggregate per share amount (payable in kind) of all
non-cash dividends or other distributions, other than a dividend payable in
shares of Common Stock or a subdivision of the outstanding shares of Common
Stock (by reclassification or otherwise), declared on the Common Stock since the
immediately preceding Quarterly Dividend Payment Date or, with respect to the
first Quarterly Dividend Payment Date, since the first issuance of any share or
fraction of a share of Series A Preferred Stock. In the event the Corporation
shall at any time declare or pay any dividend on the Common Stock payable in
shares of Common Stock, or effect a subdivision or combination or consolidation
of the outstanding shares of Common Stock (by reclassification or otherwise than
by payment of a dividend in shares of Common Stock) into a greater or lesser
number of shares of Common Stock, then in each such case the amount to which
holders of shares of Series A Preferred Stock were entitled immediately prior to
such event under clause (b) of the preceding sentence shall be adjusted by
multiplying such amount by a fraction, the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

     (B) The Corporation shall declare a dividend or distribution on the Series 
A Preferred Stock as provided in paragraph (A) of this Section immediately after
it declares a dividend or distribution on the Common Stock (other than a 
dividend payable in shares of Common Stock); provided that, in the event no 
dividend or distribution shall have been declared on the Common Stock during the
period between any Quarterly Dividend Payment Date and the next subsequent 
Quarterly Dividend Payment Date, a dividend of $1 per share on the Series A 
Preferred Stock shall nevertheless be payable on such subsequent Quarterly 
Dividend Payment Date.

     (C) Dividends shall begin to accrue and be cumulative on outstanding shares
of Series A Preferred Stock from the Quarterly Dividend Payment Date next
preceding the date of issue of such shares, unless the date of issue of such
shares is prior to the record date for the first Quarterly Dividend Payment
Date, in which case dividends on such shares shall begin to accrue from the date
of issue of such shares, or unless the date of issue is a Quarterly Dividend
Payment Date or is a


                                      -2-
<PAGE>

date after the record date for the determination of holders of shares of Series
A Preferred Stock entitled to receive a quarterly dividend and before such
Quarterly Dividend Payment Date, in either of which events such dividends shall
begin to accrue and be cumulative from such Quarterly Dividend Payment Date.
Accrued but unpaid dividends shall not bear interest. Dividends paid on the
shares of Series A Preferred Stock in an amount less than the total amount of
such dividends at the time accrued and payable on such shares shall be allocated
pro rata on a share-by-share basis among all such shares at the time
outstanding. The Board of Directors may fix a record date for the determination
of holders of shares of Series A Preferred Stock entitled to receive payment of
a dividend or distribution declared thereon, which record date shall be not more
than 50 days prior to the date fixed for the payment thereof.

     (D) The annual dividends on the Series A Preferred Stock shall be equal to 
the sum of the quarterly dividends in each year.

     Section 3. Voting Rights. The holders of shares of Series A Preferred Stock
                --------------
shall have the following voting rights:

     (A) Subject to the provision for adjustment hereinafter set forth, each 
share of Series A Preferred Stock shall entitle the holder thereof to 100 votes
on all matters submitted to a vote of the stockholders of the Corporation. In
the event the Corporation shall at any time declare or pay any dividend on the
Common Stock payable in shares of Common Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the number of votes per shares to which holders of shares of Series A
Preferred Stock were entitled immediately prior to such event shall be adjusted
by multiplying such number by a fraction, the numerator of which is the number
of shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

     (B) Except as otherwise provided herein, in any other Statement creating a 
series of Preferred Stock or any similar stock, or by law, the holders of shares
of Series A Preferred Stock and the holders of shares of Common Stock and any 
other capital stock of the Corporation


                                      -3-
<PAGE>
 
having general voting rights shall vote together as one class on all matters 
submitted to a vote of stockholders of the Corporation.

     (c) Except as set forth herein, or as otherwise provided by law, holders of
Series A Preferred Stock shall have no special voting rights and their consent 
shall not be required (except to the extent they are entitled to vote with 
holders of Common Stock as set forth herein) for taking any corporate action.

     Section 4. Certain Restrictions.
                --------------------

     (A) Whenever quarterly dividends or other dividends or distributions 
payable on the Series A Preferred Stock as provided in Section 2 are in arrears,
thereafter and until all accrued and unpaid dividends and distributions, whether
or not declared, on shares of Series A Preferred Stock outstanding shall have
been paid in full, the Corporation shall not:

     (i) declare or pay dividends, or make any other distributions, on any 
shares of stock ranking junior (either as to dividends or upon liquidation, 
dissolution or winding up) to the Series A Preferred Stock;

     (ii) declare or pay dividends, or make any other distributions, or any 
shares of stock ranking on a parity (either as to dividends or upon liquidation,
dissolution or winding up) with the Series A Preferred Stock, except dividends 
paid ratably on the Series A Preferred Stock and all such parity stock on which 
dividends are payable or in arrears in proportion to the total amounts to which 
the holders of all such shares are then entitled;

     (iii) redeem or purchase or otherwise acquire for consideration shares of 
any stock ranking junior (either as to dividends or upon liquidation, 
dissolution or winding up) to the Series A Preferred Stock, provided that the 
Corporation may at any time redeem, purchase or otherwise acquire shares of any 
such junior stock in exchange for shares of any stock of the Corporation ranking
junior (either as to dividends or upon dissolution, liquidation or winding up) 
to the Series A Preferred Stock; or

     (iv) redeem or purchase or otherwise acquire for consideration any shares 
of Series A Preferred Stock, or any shares of stock ranking on a parity with the
Series A Preferred Stock, except in accordance with a


                                      -4-
<PAGE>
 
purchase offer made in writing or by publication (as determined by the Board of 
Directors) to all holders of such shares upon such terms as the Board of 
Directors, after consideration of the respective annual dividend rates and other
relative rights and preferences of the respective series and classes, shall 
determine in good faith will result in fair and equitable treatment among the 
respective series or classes.

     (B) The Corporation shall not permit any subsidiary of the Corporation to 
purchase or otherwise acquire for consideration any shares of stock of the 
Corporation unless the Corporation could, under paragraph (A) of this Section 4,
purchase or otherwise acquire such shares at such time and in such manner.

     Section 5.  Reacquired Shares.  Any shares of Series A Preferred Stock 
                 ------------------
purchased or otherwise acquired by the Corporation in any manner whatsoever 
shall be retired and cancelled promptly after the acquisition thereof. All such 
shares shall upon their cancellation become authorized but unissued shares of 
Preferred Stock and may be reissued as part of a new series of Preferred Stock 
subject to the conditions and restrictions on issuance set forth herein, in the 
Restated Articles of Incorporation, as amended, of the Corporation, or in any 
other Statement creating a series of Preferred Stock or any similar stock or as 
otherwise required by law.

     Section 6.  Liquidation, Dissolution or Winding Up.  Upon any liquidation, 
                 ---------------------------------------
dissolution or winding up of the Corporation, no distribution shall be made (1) 
to the holders of shares of stock ranking junior (either as to dividends or upon
liquidation, dissolution or winding up) to the Series A Preferred Stock unless, 
prior thereto, the holders of shares of Series A Preferred Stock shall have 
received $100 per share, plus an amount equal to accrued and unpaid dividends 
and distributions thereon, whether or not declared, to the date of such payment,
provided that the holders of shares of Series A Preferred Stock shall be 
entitled to receive an aggregate amount per share, subject to the provision for 
adjustment hereinafter set forth, equal to 100 times the aggregate amount to be 
distributed per share to holders of shares of Common Stock, or (2) to the 
holders of shares of stock ranking on a parity (either as to dividends or upon 
liquidation, dissolution or winding up) with the Series A Preferred Stock,
except distributions made ratably on the Series A Preferred Stock and all such
parity stock in proportion to the total amounts to which the holders of all such
shares are entitled upon such liquidation, dissolution or winding up. In the
event the Corporation shall


                                      -5-
<PAGE>
 
at any time declare or pay any dividend on the Common Stock payable in shares of
Common Stock, or effect a subdivision or combination or consolidation of the 
outstanding shares of Common Stock (by reclassification or otherwise than by 
payment of a dividend in shares of Common Stock) into a greater or lesser number
of shares of Common Stock, then in each such case the aggregate amount to which 
holders of shares of Series A Preferred Stock were entitled immediately prior to
such event under the provison in clause (1) of the preceding sentence shall be 
adjusted by multiplying such amount by a fraction the numerator of which is the 
number of shares of Common Stock outstanding immediately after such event and 
the denominator of which is the number of shares of Common Stock that were 
outstanding immediately prior to such event.

     Section 7.  Consolidation, Merger, etc.  In case the Corporation shall 
                 -------------------------- 
enter into any consolidation, merger, combination or other transaction in which 
the shares of Common Stock are exchanged for or changed into other stock or 
securities, cash and/or any other property, then in any such case each share of 
Series A Preferred Stock shall at the same time be similarly exchanged or 
changed into an amount per share, subject to the provision for adjustment 
hereinafter set forth, equal to 100 times the aggregate amount of stock, 
securities, cash and/or any other property (payable in kind), as the case may 
be, into which or for which each share of Common Stock is changed or exchanged. 
In the event the Corporation shall at any time declare or pay any dividend on 
the Common Stock payable in shares of Common Stock, or effect a subdivision or 
combination or consolidation of the outstanding shares of Common Stock (by 
reclassification or otherwise than by payment of a dividend in shares of Common 
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the amount set forth in the preceding sentence with respect to the
exchange or change of shares of Series A Preferred Stock shall be adjusted by
multiplying such amount by a fraction, the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

     Section 8.  No Redemption.  The shares of Series A Preferred Stock shall 
                 -------------
not be redeemable.

     Section 9.  Fractional Shares.  The Corporation may issue fractions and 
                 ------------------
certificates representing fractions of a share of Series A

                                      -6-
<PAGE>
 
Preferred Stock in integral multiples of 1/100th of a share of Series A
Preferred Stock, or in lieu thereof, at the election of the Board of Directors
of the Corporation at the time of the first issue of any shares of Series A
Preferred Stock, evidence such fractions by depositary receipts, pursuant to an
appropriate agreement between the Corporation and a depositary selected by it,
provided that such agreement shall provide that the holders of such depositary
receipts shall have all the rights, privileges and preferences to which they
would be entitled as beneficial owners of shares of Series A Preferred Stock. In
the event that fractional shares of Series A Preferred Stock are issued, the
holders thereof shall have all the rights provided herein for holders of full
shares of Series A Preferred Stock in the proportion which such fraction bears
to a full share.

     Section 10.  Amendment.  The Restated Articles of Incorporation, as 
                  ----------
amended, of the Corporation shall not be amended in any manner which would
materially alter or change the powers, preferences or special rights of the
Series A Preferred Stock so as to affect them adversely without the affirmative
vote of the holders of at least two-thirds of the outstanding shares of Series A
Preferred Stock, voting together as a single class.

      (a) For purposes of establishing a Reserve, an amount shall be set aside

          (1)  Multiply consolidated shareholders' equity as of the beginning of
               the year by 12%;

          (2)  Subtract the result of (1) above from Pre-tax Earnings for the
               year;

          (3)  Multiply the result of (2) above by 5%.

      (b) In no event, may the amount set aside exceed 20% of the cash dividends
          paid on PPG Stock during the year.

      (c) For purposes of subparagraph (a)(1) above, "shareholders' equity"
          shall be exclusive of the aggregate par or stated value of preferred

          thereon.

      (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
          been in the Reserve for the longest period of time.

      (e) Unawarded amounts set aside prior to the fourth preceding year shall
          be automatically released from the Reserve and returned to income.

      (f) The Reserve shall not be reduced by interest or dividend equivalents

          amount to be set aside in the Reserve for such year and unawarded
          amounts in the Reserve) to a group of Employees without determining
          the amounts to be allocated to individuals in such group and such
          allocation shall create a legal obligation upon the Company to pay
          such amount to the individuals comprising such group.

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

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.

                                 - Page 9.1 -
<PAGE>
 
      (b) By way of example of the operation of paragraph (a) above:

          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

<PAGE>
 
     (2)  Participants who elect to receive installments, must specify the
          quarter/year that such installments will begin; provided, however,
          that the Participant must elect to begin installments no later than
          the last quarter of the year in which the fifth anniversary of his/her
          termination date occurs.  Installments must begin no earlier than the
          Plan Year after the Plan Year of the Participant's termination and as

          1/5 of Account; 2nd installment = 1/4 of Account, etc.).  If the

          continuation of the Declared Rate, on a case-by-case basis.

     (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

          the Unscheduled Withdrawal amount shall be withheld and forfeited (or

          The Administrator shall afford the claimant, or his/her authorized
          representative, an opportunity to review documents pertinent to the
          claim, and shall conduct a full and fair review of the claim and its
          denial.  The Administrator's decision on such review shall be
          furnished to the claimant in writing, and shall be written in a manner
          calculated to be understandable to the claimant.  Such decision shall

          upon.

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

          election by the Company's shareholders, was approved by a vote of at
          least a majority of the directors then comprising the Incumbent Board
          shall be considered as though such individual were a member of the
          Incumbent Board, but excluding, for this purpose, any such individual
          whose initial assumption of office occurs as a result of an actual or

          consents by or on behalf of a Person other than the Board; or

               the corporation resulting from such Business Combination
               (including, without limitation, a corporation which as a result
               of such transaction owns the Company or all or substantially all
               of the Company's assets either directly or through one or more
               subsidiaries) in substantially the same proportions as their
               ownership, immediately prior to such Business Combination of the
               Outstanding Company Common Stock and Outstanding Company Voting
               Securities, as the case may be;


          (ii) No Person (excluding any employee benefit plan (or related trust)

               ownership existed prior to the Business Combination; and

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

     (d) Approval by the shareholders of the Company of a complete liquidation
         or dissolution of the Company; or
        
     (e) A majority of the Board otherwise determines that a Change in Control

          to such dividends shall be paid in cash to the Participant.

      (a) A Participant may elect to defer receipt of a Payment in accordance
          with this Section 2.05.

      (b) A Participant may elect to defer either 25%, 50%, 75% or 100% of

          cash, as determined in accordance with Section 2.04(b).

      (c) Except as otherwise provided in paragraph (c) below, all elections
          pursuant to this Section 2.05 must be filed with the Administrator no
          later than the last day of the first year of the Award Period; and
          such election shall become irrevocable as of the first day of the

          would otherwise be made following the Award Period and shall be
          subject to the provisions of the Deferred Compensation Plan.

      If a Participant's employment with the Corporation terminates during an
      Award Period because of retirement, and after the Employee has been a
      Participant for at least 12 months of the Award Period, the Participant
      shall be entitled to a prorated Award which shall be determined at the end
      of the Award Period. Such prorated Award shall be determined by
      multiplying the Award to which the Participant would otherwise have been
      entitled by a fraction - the numerator of which is the number of months
      the Participant was employed during the Award Period and the denominator
      of which is the total number of calendar months in the Award Period.

3.02  Disability

      If a Participant's employment with the Corporation terminates during an
      Award Period because of Disability, and after the Employee has been a
      Participant for at least 12 months of the Award Period, the Participant
      shall be entitled to a prorated Award which shall be determined at the end
      of the Award Period. Such prorated Award shall be determined by
      multiplying the Award to which the Participant would otherwise have been
      entitled by a fraction - the numerator of which is the number of months
      the Participant was employed during the Award Period and the denominator
      of which is the total number of calendar months in the Award Period.

3.03  Death

      If a Participant's employment with the Corporation terminates during an
      Award Period because of the Participant's death, and after the Employee
      has been a Participant for at least 12 months of the Award Period, the
      Participant's Beneficiary shall be entitled to a prorated Award which
      shall be determined at the end of the Award Period. Such prorated Award
      shall be determined by multiplying the Award to which the Participant
      would otherwise have been entitled by a fraction - the numerator of which
      is the number of months the Participant was employed during the Award
      Period and the denominator of which is the total number of calendar months
      in the Award Period.

3.04  Termination

      If a Participant's employment with the Corporation terminates during an
      Award Period for any reason other than retirement, Disability or Death,

      (a) Except as provided in paragraph (b) below and in section 5.02, no
          person shall have any power to encumber, sell, alienate, or otherwise
          dispose of his/her interest under the Plan prior to actual payment to
          and receipt thereof by such person; nor shall the Administrator
          recognize any assignment in derogation of the foregoing.  No interest
          hereunder of any person shall be subject to attachment, execution,
          garnishment or any other legal, equitable, or other process.

      (b) Paragraph (a) above shall not apply to the extent that a Participant's
          interest under the Plan is alienated pursuant to a "Qualified Domestic
          Relations Order" ("QDRO") as defined in (S)414(p) of the Code.

          (1)  The administrator is authorized to adopt such procedural and
               substantive rules and to take such procedural and substantive

               provide for the payment of amounts from the Plan to an Alternate
               Payee as provided in a QDRO.  Such rules and actions shall be
               consistent with the principal purposes of the Plan.

          (2)  Under no circumstances may the Administrator accept an order as a
               QDRO following a Participant's death.

          (3)  TSR Shares shall not be payable to an Alternate Payee until such
               shares would otherwise be payable to a Participant.

4.02  Beneficiary Designation
      -----------------------

      (a) The Participant shall have the right, at any time, to designate any
          person(s) as Beneficiary.  The designation of a Beneficiary shall be
          effective on the date it is received by the Administrator, provided
          the Participant is alive on such date.

      (b) Each time a Participant submits a new Beneficiary designation form to
          the Administrator, such designation shall cancel all prior
          designations.

      (c) In the case of a Participant who does not have a valid Beneficiary
          designation on file at the time of his/her death, or in the case the
          designated Beneficiary predeceases the Participant, any Payment to
          which the Participant would have been entitled shall be paid to the
          Participant's estate at the end of the Award Period.

      (a) No Employee or other person shall have any claim or right to be
          granted an Award under the Plan.

      (b) The Benefits paid under the Plan shall be paid from the general funds
          of the Company and from shares authorized and available for issuance
          under the Original Plan, and the Participants and any Beneficiary
          shall be no more than unsecured general creditors of the Company with
          no special or prior right to any assets of the Company for payment of
          any obligations hereunder.

4.04  Forfeiture Provision

      Notwithstanding any other provisions herein:

      (a) If at any time within the Award Period or within one year after the
          Award Period, the Participant engages in any activity in competition
          with any activity of the Corporation, or contrary or harmful to the
          interests of the Corporation, including, but not limited to:

          (1)  Conduct related to the Participant's employment for which either
               criminal or civil penalties against the Participant may be
               sought; or

          (2)  Violation of the Corporation's Business Conduct Policies; or

          (3)  Accepting employment with or serving as a consultant, advisor or
               in any other capacity to an employer that is in competition with
               or acting against the interests of the Corporation, including
               employing or recruiting any present, former or future employee of
               the Corporation; or

          (4)  Disclosing or misusing any confidential information or material

          then the Award shall terminate effective on the date on which the
          Committee determines that Participant has engaged in such activity.
          Any "Award Gain" realized by the Participant shall be paid by the
          Participant to the Company. For purposes of this Section 4.04, "Award
          Gain" shall mean the cash and the closing market price of the Common
          Stock delivered to the Participant pursuant to an Award. Any portion
          of a Payment which was deferred shall be forfeited from the
          Participant's account in the Deferred Compensation Plan in accordance
          with this Section 4.04.


      (b) By executing the Award Agreement, the Participant shall agree to a
          deduction from any amounts the Corporation owes the Participant from
          time to time (including amounts owed to the Participant as wages or
          other compensation, fringe benefits or vacation pay, as well as any
          other amounts owed to the Participant), to the extent of amounts owed
          to the Corporation in accordance with paragraph (a) above.  Whether or
          not the Corporation elects to make any set-off in whole or in part, if
          the Corporation does not recover by means of set-off the full amount
          the Participant owes in accordance with paragraph (a), the Participant
          agrees to pay the unpaid balance to the Corporation immediately upon
          notification by the Administrator.

      (c) The Participant may be released from the Participant's obligations
          under paragraphs (a) and (b) above only if the Committee determines,
          in its sole discretion, that such action is in the best interest of
          the Corporation.

4.05  Taxes

      The Corporation shall have the right to deduct, or to require the
      Participant or other person receiving a payment under the Plan to pay to
      the Corporation any Federal or state taxes required by law to be withheld
      or paid.

          payment made under the provisions of the paragraph (a) shall be a
          complete discharge of any liability therefor under the Plan.  The
          Administrator shall not be required to see to the proper application
          of any such payment.

      (b) Claims Procedure

          Within sixty (60) days of the date the Administrator denies a claim,
          in whole or in part, the claimant, or his/her authorized

          The Administrator shall afford the claimant, or his/her authorized
          representative, an opportunity to review documents pertinent to the
          claim, and shall conduct a full and fair review of the claim and its
          denial.  The Administrator's decision on such review shall be

          Common Stock by reason of any stock dividend, stock split,
          reorganization, merger, consolidation, exchange of shares or similar
          change, a corresponding change shall be made in:

      Plan. At its discretion, the Company may establish one or more grantor
      trusts for the purpose of providing for payment of benefits under the
      Plan. Such trust(s) may be irrevocable, but the assets thereof shall be
      subject to the claims of the Company's creditors. Benefits paid to the
      Participant from any such trust shall be considered paid by the Company
      for purposes of meeting the obligations of the Company under the Plan.

7.05  Employment Not Guaranteed

                        ------------------------------
                                        
8.01  Payments to a Trustee

      Upon, or in reasonable anticipation of a Change in Control, as defined in
      Section 8.02, all contingent Awards outstanding shall be deemed to have
      been earned on such basis as the Committee shall prescribe and then paid
      to a trustee or otherwise on such terms as the Committee may prescribe or
      permit and any deferred amounts shall be paid to a trustee or otherwise in
      such form and on such terms as the Committee may prescribe or permit.

8.02  Definition:  Change in Control

      A "Change in Control" shall mean:

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

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

          Any acquisition directly from the Company;

          Any acquisition by the Company;

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

          Any acquisition by any corporation pursuant to a transaction which
          complies with clauses (i), (ii) and (iii) of paragraph (c) of this
          section 8.02.

      (b) Individuals who, as of January 1, 1999, constitute the Board (the
          "Incumbent Board") cease for any reason to constitute at least a
          majority of the Board; provided, however, that any individual becoming
          a director subsequent to such date whose election, or nomination for
          election by the Company's shareholders, was approved by a vote of at
          least a majority of

                                 - Page 8.1 -
<PAGE>
 
          the directors then comprising the Incumbent Board shall be considered
          as though such individual were a member of the Incumbent Board, but
          excluding, for this purpose, any such individual whose initial
          assumption of office occurs as a result of an actual or threatened
          election contest with respect to the election or removal of directors
          or other actual or threatened solicitation of proxies or consents by
          or on behalf of a Person other than the Board; or

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

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

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

                                 - Page 8.2 -
<PAGE>
 
          (iii) At least a majority of the members of the board of directors of
                the corporation resulting from such Business Combination were
                members of the Incumbent Board at the time of the execution of
                the initial agreement, or of the action of the Board, providing
                for such Business Combination; or

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

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

                        Financial and Operating Review
- -------------------------------------------------------------------------------
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
subsidiaries as of December 31, 1998 and 1997, and the related statements of
income, comprehensive income, shareholders' equity and cash flows for each of
the three years in the period ended December 31, 1998. These financial state-
ments 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, 1998 and 1997, and the results of their operations and their cash
flows for each of the three years in the period ended December 31, 1998 in
conformity with generally accepted accounting principles.

Management Statement
 
Responsibility for Preparation of the Financial Statements
The management of PPG Industries, Inc. is responsible for the preparation of
the financial statements included in this Annual Report.
 To ensure the reliability of financial data, PPG has established, and main-
tains, an internal control system. We believe the internal controls in use
give reasonable assurance that financial reports do not contain any material
misstatement.
 We believe that the financial statements and related notes in this report are
accurate in all material respects, and that they were prepared according to
generally accepted accounting principles. The financial statements include
amounts that are based on the best estimates and judgments of management.
 We believe, further, that the other financial information contained in this
Annual Report is consistent with the financial statements.

                      Management's Discussion and Analysis
- --------------------------------------------------------------------------------
Performance in 1998 Compared with 1997
Overall Performance
Our sales in 1998 increased 2% to $7.5 billion from $7.4 billion in 1997. The
sales increase resulted from an 8% increase in volumes, including sales related
to several acquisitions made in late 1997 and in 1998, primarily within our
coatings segment. These sales increases were offset in part by a 4% decline due
to the absence of sales related to the divestitures of our European flat and
automotive glass businesses in July 1998 and our surfactants business in Novem-
ber 1997, a 1% decline in sales associated with lower prices for chlorine prod-
ucts in our chemicals segment and a 1% decline from foreign currency transla-
tion due to the strengthening of the U.S. dollar.
 The gross profit percentage remained relatively constant at 40.4% in 1998 and
1997. The combination of improved manufacturing efficiencies across all of our
business segments and lower raw materials costs in our chemicals segment was
substantially offset by lower sales prices for chlorine products and certain
glass products and the negative effects of inflation in our coatings and glass
segments.
 Net income and earnings per common share, diluted, for 1998 increased to $801
million and $4.48, respectively, compared to net income and earnings per common
share, diluted, of $714 million and $3.94, respectively, for 1997. The increase
in 1998 net income resulted from an $82 million after-tax gain from the sale of
our European flat and automotive glass businesses, a significant reduction in
business divestiture and realignment charges, insurance recoveries of certain
past environmental costs and the same factors that contributed to the increased
sales described above. These improvements were partially offset by the absence
of the gain from the 1997 sale of our surfactants business, higher expenses as-
sociated with worldwide growth initiatives in our coatings segment, the nega-
tive effects of inflation, higher income tax expense due to increased pre-tax
earnings, the effects of the 1998 General Motors strike and the impact of ad-
verse economic conditions in Asia.
 
Results of Business Segments
Coatings sales increased 13% to $3.5 billion in 1998 from $3.1 billion in 1997.
A 14% increase in sales volume included sales from recent acquisitions and vol-
ume increases for our worldwide automotive refinish, industrial and architec-
tural coatings products and for our automotive original coatings products in
Europe and North America. These sales increases were slightly offset by a 1%
decline from foreign currency translation. Sales generated from worldwide ac-
quisitions in 1998 and late 1997 contributed substantially to the segment's
sales growth in 1998. The unfavorable effects of the General Motors strike par-
tially offset the sales volume improvements in our North American automotive
original and industrial coatings businesses. Operating income decreased to $546
million in 1998 compared to $561 million in 1997. The decrease in operating in-
come is attributable to higher expenses associated with worldwide growth
initiatives in our automotive refinish and industrial businesses, the negative
effects of inflation, particularly on our European businesses, restructuring
charges related to cost reduction initiatives, the impact of the General Motors
strike and reduced royalty income. These reductions were partially offset by
the previously discussed volume improvements and the favorable effect of earn-
ings from recently acquired businesses.
 Glass sales decreased 5% to $2.5 billion in 1998 from $2.7 billion in 1997.
Sales declined 7% as a result of the divestiture of our European flat and
automotive glass businesses effective July 31, 1998, 1% due to the unfavorable
effects of foreign currency translation and 1% from lower fiber glass product
volumes. These negative factors were partially offset by a 4% sales volume
increase, principally for North American automotive replacement glass products
and an acquisition of an automotive original glass products facility in early
1998. Additionally, worldwide sales price improvements for fiber glass products
were more than offset by lower sales prices for North American automotive
original glass and flat glass products. The increase in operating income to
$478 million in 1998 compared to $286 million in 1997 is attributable to an $85
million pre-tax gain from the sale of our European flat and automotive glass
businesses, a reduction in business divestiture and realignment charges to $21
million from $102 million in 1997, improved manufacturing efficiencies,
particularly in our North American automotive original glass business and
increased equity affiliate earnings. These favorable factors were partially
offset by the negative effects of inflation, the sales price reductions
mentioned above and the impact of the General Motors strike.
 Chemicals sales decreased 7% to $1.5 billion in 1998 from $1.6 billion in
1997. A 7% reduction in sales volumes associated with the divestiture of the
surfactants business in late 1997 and a 5% decline related to lower sales
prices were partially offset by a 5% increase in sales volumes for specialty
chemicals. Significantly lower sales prices were experienced for chlor-alkali
and derivative products. Specialty chemical volumes increased due primarily to
demand for Transitions(Registered Trademark) optical lenses and the acquisition
in late 1997 of a pharmaceutical intermediates company. Operating income in 1998
decreased to $354 million from $428 million in 1997. The decrease in operating
income is attributable to a decline in chlor-alkali and derivative product
prices and the absence of a $59 million pre-tax gain from the sale of and
earnings associated with our surfactants business. These unfavorable factors
were partially offset by lower raw material

costs within our chlor-alkali and derivatives business, lower environmental
costs, an insurance recovery of certain past environmental costs and the sales
volume increases discussed above.
 
Other Significant Factors
The reduction in the overall effective tax rate in 1998 was primarily attribut-
able to the realization of the benefits of capital loss carryforwards on the
gain from the sale of our European flat and automotive glass businesses.
 Goodwill increased due to acquisition activity in 1998. The increase in other
long-term assets was attributable principally to an increase in our prepaid
pension asset and to an increase in other intangible assets resulting from 1998
acquisition activity.
 
Outlook
Although the rate of economic growth is expected to moderate in 1999 in North
America and Europe, PPG should experience an increase in volume, principally as
a result of our commercialization of new products, the expansion of our market
presence and the inclusion of a full year's results associated with businesses
acquired in 1998. We also expect to continue our acquisition activity in 1999,
which should further contribute to volume increases.
 During 1998, we were adversely affected by the economic weakness in Asia. Our
businesses within the region were directly affected by the economic conditions.
Furthermore, our chlor-alkali and fiber glass businesses experienced an indi-
rect effect as exports to Asia declined and imports from Asia into North Amer-
ica and Europe resulted in increased competition and lower selling prices for
our chlor-alkali products. We expect the economic weakness in Asia to continue
in 1999, which may result in continued pressure on selling prices for our
chlor-alkali products, some fiber glass products and our automotive replacement
glass products. In addition, the economic weakness and currency devaluation in
Brazil during 1999 are expected to adversely affect our automotive coatings and
refinish operations in that country. However, to the extent we are adversely
affected by the economic weakness in Asia, we anticipate a benefit due to lower
raw materials costs in the chemicals and coatings businesses.
 If the current economic weakness in Brazil spreads to other countries in South
America or to Mexico, it may result in a weaker North American economy which
could adversely affect certain operations within our coatings, glass and chemi-
cals segments.
 
Accounting Standards
In March 1998, the Accounting Standards Executive Committee of the American In-
stitute of Certified Public Accountants issued Statement of Position 98-1, "Ac-
counting for the Costs of Computer Software Developed or Obtained for Internal
Use," which is effective for fiscal years beginning after Dec. 15, 1998. The
adoption of this new standard in 1999 will not have a material effect on the
Company's financial position or results of operations.
 In June 1998, the Financial Accounting Standards Board issued Statement of Fi-
nancial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities," which is effective for fiscal years beginning after
June 15, 1999. The Company is currently evaluating the prospective impact of
this standard on its financial position and results of operations.
 
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% in 1997 from 39.9% in 1996. The
benefits realized from improved manufacturing efficiencies, particularly in our
glass and chemicals segments, favorable sales mix changes within our chemicals
and coatings segments, and slightly higher sales prices and lower raw materials
costs within our coatings segment contributed to the increase. These improve-
ments were partially offset by lower overall sales prices in our glass segment
and for caustic soda in our chemicals segment, as well as the negative effects
of inflation on our glass and chemicals segments.
 Net income and earnings per common share, diluted, for 1997 were $714 million
and $3.94, respectively, compared with $744 million and $3.93, 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 divest-
iture and realignment charges of $102 million associated with our glass opera-
tions; higher overhead costs associated with growth initiatives in our coatings
segment; increased advertising, selling and environmental expenses in our chem-
icals segment; the negative effects of inflation and foreign currency transla-
tion, and a slight increase in interest costs associated with higher outstand-
ing 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 ex-
pense.

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 automo-
tive 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 $561 million in 1997, compared with $519 million in 1996. The earnings im-
provement was attributable to the same volume and price factors that contrib-
uted 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 currency
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 $286 mil-
lion in 1997 compared with $429 million in the prior year. The decrease was at-
tributable to 1997 pre-tax charges totaling $102 million for restructuring ac-
tions related principally to the closing of our Perry, Ga., float glass plant
and the planned disposition of our equity interests in two Asian float glass
plants, the sales price reductions mentioned above, the negative effects of in-
flation and foreign currency translation, and slightly higher legal expenses.
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(Registered Trademark) 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 business, which was divested late in 1997. Operating
income increased to $428 million in 1997 from $374 million in 1996, and
included a $59 million pre-tax gain from the sale of our surfactants business.
Excluding this gain, operating earnings declined $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 manufacturing 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(Registered Trademark) optical lenses, the negative effects of
inflation on raw material costs, and higher environmental and legal expenses.
 
Business Divestitures and Realignments
During 1998, we approved a restructuring plan principally associated with cost
reduction initiatives in our glass and coatings operations. We recorded a pre-
tax charge of $19 million in connection with this plan. The components of the
plan include severance benefits for 283 employees. As of Dec. 31, 1998, $2 mil-
lion had been paid under the plan and it is anticipated that the remainder will
be paid in 1999. We also recorded in 1998 an additional pre-tax charge of $15
million related to the disposition of our equity interests in two Asian float
glass plants and two Asian downstream fabrication facilities. The $15 million
pre-tax charge related to a reassessment of the proceeds expected to be real-
ized on the dispositions of $14 million and asset write-offs of $1 million. Ad-
ditionally, in 1998 we recorded a $3 million reversal of a reserve, originally
recorded in 1997, related to the closure of our Perry, Ga., flat glass plant.
 In 1997 we recorded a pre-tax restructuring charge of $102 million related to
certain glass businesses that were not meeting strategic and performance objec-
tives. The principal components of the 1997 restructuring program included the
closure of our Perry, Ga., flat glass plant and the disposition of our equity
interests in two Asian float glass plants. The pre-tax restructuring charge in
1997 included $61 million of asset write-offs and $41 million associated with
cash outlays primarily for severance costs (317 employees), a proportionate
share of equity investee indebtedness, and demolition and environmental costs,
net of estimated proceeds from sale. During 1998, cash outlays associated with
both the 1997 restructuring program and the additional restructuring charge re-
corded in 1998 related to this program totaled $11 million. We also reversed $3
million of the 1997 restructuring charge in 1998. It is anticipated that the
remaining reserves related to the 1997 restructuring program of $41 million at
Dec. 31, 1998, will be paid in 1999.

                      Management's Discussion and Analysis
- --------------------------------------------------------------------------------
Commitments and Contingent Liabilities, including Environmental Matters
PPG is involved in a number of lawsuits and claims, both actual and potential,
including some that it has asserted against others, in which substantial money
damages are sought. These lawsuits and claims relate to product liability, con-
tract, patent, environmental, antitrust and other matters arising out of the
conduct of PPG's business. The Company has been named in a number of antitrust
lawsuits alleging that PPG acted with competitors to fix prices and allocate
markets for certain glass products. These antitrust proceedings are in an early
stage. 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, in the aggregate, the outcome
of all lawsuits and claims involving PPG 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, 1998 and
1997, PPG had reserves for environmental contingencies totaling $94 million and
$100 million, respectively. Pre-tax charges against income for environmental
remediation costs in 1998, 1997 and 1996 totaled $10 million, $34 million and
$27 million, respectively, and are included in "Other charges" in the statement
of income. Cash outlays related to such charges aggregated $16 million, $25
million and $36 million in 1998, 1997 and 1996, 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
significant portion of such exposure involves three operating plant sites.
Initial remedial actions are occurring at these sites. Studies 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 exposure 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
potentially 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 major 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, the cost of sales reported in the financial statements approximates
current costs.
 In 1998 the overall decline in sales prices was partially offset by improved
manufacturing efficiencies and the overall positive impacts of inflation on our
production costs. In 1997 and 1996, the increase in production costs due to the
negative effects of inflation was not fully recovered through price increases
and manufacturing efficiencies. While inflationary pressure on costs is ex-
pected to be experienced in 1999, we anticipate that ongoing improvements in
manufacturing efficiencies, as well as raw material

                      Management's Discussion and Analysis
- --------------------------------------------------------------------------------
substitution and increases in selling prices for certain products, will miti-
gate to a significant extent the negative impact of inflation on 1999 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 $942 million in 1998, $1,007 mil-
lion in 1997 and $1,008 million in 1996. Dividends paid to shareholders totaled
$252 million in 1998, $239 million in 1997 and $237 million in 1996. Contribu-
tions to U.S. pension plans totaled $109 million in 1996.
 During 1998, 1997 and 1996, the Company repurchased approximately 2.1 million,
5.3 million and 11.9 million shares of common stock at a cost of $122 million,
$302 million and $606 million, respectively, under various share repurchase
programs. The most recent program authorized the repurchase of 10 million
shares of common stock, and was initiated in November 1998. As of Dec. 31,
1998, 2.0 million shares of common stock had been repurchased under the most
recent program at a cost of $114 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
scheduled 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. The proceeds from the issuance of the notes were
used for general corporate purposes, including the repayment of commercial pa-
per borrowings.
 Capital spending in 1998 totaled $877 million, compared with $829 million in
1997 and $489 million in 1996. This spending related to modernization and pro-
ductivity improvements, expansion of existing businesses, environmental control
projects and, in 1998, 1997 and 1996, business acquisitions totaling $390 mil-
lion, $363 million and $13 million, respectively. Capital spending of a similar
nature, excluding acquisitions, is expected to total about $600 million during
1999.
 In 1999 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 37% and 40% at Dec. 31, 1998 and 1997, 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 5, 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 of debt securities under a shelf registration state-
ment filed with the Securities and Exchange Commission (SEC) in January 1998.
 
Conversion to the Euro
On Jan. 1, 1999, eleven of the member countries of the European Monetary Union
converted from their sovereign currencies to a common currency, the euro. At
that time, fixed conversion rates between the legacy currencies and the euro
were set. The legacy currencies will remain legal tender from Jan. 1, 1999,
through July 1, 2002. Beginning Jan. 1, 2002, euro-denominated currency will be
issued. No later than July 1, 2002, the participating countries will withdraw
all bills and coins so that their legacy currencies will no longer be consid-
ered legal tender.
 PPG has identified the significant issues that may result from the euro con-
version and is addressing them. These issues include increased competitive
pressures from greater price transparency, changes to information systems to
accommodate various aspects of the new currency and exposure to market risk
with respect to financial instruments. PPG does not expect the impact on its
operating results or financial condition from the conversion to be material.
 
Forward-Looking Statements
The Private Securities Litigation Reform Act of 1995 provides a safe harbor for
forward-looking statements made by or on behalf of the Company. Management's
Discussion and Analysis and other sections of this Annual Report contain for-
ward-looking statements that reflect the Company's current views with respect
to future events and financial performance.
 Forward-looking statements are identified by the use of the words "aim," "be-
lieve," "expect," "anticipate," "intend," "estimate" and other expressions that
indicate future events and trends. Any forward-looking statement speaks only as
of the date on which such statement is made and the Company undertakes no obli-
gation to update any forward-looking statement, whether as a result of new in-
formation, future events or otherwise. You are advised, however, to consult any
further disclosures we make on related subjects in our Form 10-Q, 8-K and 10-K
reports to the SEC. Also, note the following cautionary statements.
 Many factors could cause actual results to differ materially from the
Company's forward-looking statements. Among these factors are increasing price
and product competition

by foreign and domestic competitors, fluctuations in the cost and availability
of raw materials, the ability to maintain favorable supplier relationships and
arrangements, economic and political conditions in international markets, the
ability to penetrate existing, developing and emerging foreign and domestic
markets, which also depends on economic and political conditions, foreign ex-
change rates and fluctuations in those rates, and the uncertainties regarding
the Year 2000 problem discussed below. Further, one should understand that it
is not possible to predict or identify all such factors. Consequently, while
the list of factors presented here is considered representative, no such list,
including the one here, should be considered to be a complete statement of all
potential risks and uncertainties. Indeed, unlisted factors may present signif-
icant additional obstacles to the realization of forward-looking statements.
 The following discussion regarding Year 2000 issues, including the discussion
of the timing and effectiveness of implementation and the estimated cost of the
Company's Year 2000 efforts, contains forward-looking statements derived using
various assumptions of future events. These forward-looking statements involve
inherent risks and uncertainties, and the actual results could differ materi-
ally from those contemplated by such statements.
 Factors that could cause material differences in results -- many of which are
outside the control of the Company -- include, but are not limited to:
 .  PPG's ability to locate and correct all relevant computer software.
 .  The accuracy of representations by manufacturers of the Company's computer
   systems and software that their products are Year 2000 compliant.
 .  The ability of our suppliers, customers and other counterparties to identify
   and resolve their own Year 2000 obligations so as to allow them to continue
   normal business operations or furnish products, services or data to PPG
   without disruption.
 .  Our ability to respond to unforeseen Year 2000 complications.
 The consequences of material differences in the results as compared to those
anticipated in the forward-looking statements could include, among other
things, business disruption, operational problems, financial loss, legal lia-
bility to third parties and similar risks, any of which could have a material
adverse effect on our consolidated financial condition, operations or
liquidity.
 
Year 2000 Readiness Disclosure
Background
Many existing information technology (IT) products and systems, and non-IT
products and systems containing embedded microchip processors, were originally
programmed to represent any calendar dates by using six digits (for example,
12/31/99), as opposed to eight digits (for example, 12/31/1999). Accordingly,
such products and systems may experience miscalculations, malfunctions or dis-
ruptions when attempting to process information containing dates that fall af-
ter Dec. 31, 1999, or other dates that could cause computer malfunctions. These
potential problems are collectively referred to as the "Year 2000" problem.
 
State of Readiness
Recognizing the importance of Year 2000 issues, we have established a corpo-
rate-wide Year 2000 Steering Committee made up of certain senior executives of
the Company. The Committee is responsible for overseeing our efforts to assess
and address the Year 2000 problem as it may affect the Company. The scope of
our efforts includes (1) an assessment, and where needed a remediation, of both
IT and non-IT elements of our business information, computing, telecommunica-
tions, and process control systems; (2) an assessment, and remediation, as nec-
essary, of equipment with embedded computer chips, and (3) an evaluation of the
Company's relationships with material third parties as they may be impacted by
the Year 2000 problem.
 The phases of the Company's Year 2000 compliance plan are: (1) Internal As-
sessment -- a detailed evaluation of the potential Year 2000 effects on the
Company's IT and non-IT systems and on its equipment with embedded computer
chips; (2) Remediation -- corrective action including code enhancements,
hardware and software upgrades, system replacements, vendor certification,
equipment repair or replacement, and other associated changes to achieve Year
2000 compliance; (3) Testing -- the verification that remediation actions are
effective; (4) Third-Party Evaluation -- an evaluation of the Year 2000
readiness of key suppliers of goods and services and of key customers, and (5)
Contingency Planning -- the development of detailed procedures to be put in
place should the Company or key suppliers or customers experience a significant
Year 2000 problem. These phases sometimes overlap.
 The assessment phase is complete with the exception of certain recently ac-
quired businesses where the assessment phase is in progress and is expected to
be completed by March 31, 1999. The remediation effort is well under way on all
critical IT and non-IT systems, and we presently anticipate that we will sub-
stantially complete remediation of such critical systems by June 30, 1999, and
that remediation and testing of all remaining systems will be completed by Dec.
31, 1999. Once systems undergo remediation, they are tested for Year 2000 com-
pliance. For major systems, the testing process usually involves subjecting the
remediated system to a simulated change of date from the year 1999 to the year
2000 using, in many cases, computer resources

dedicated to that purpose so that normal computing activity is not interrupted
or adversely affected by the testing. We are currently in the process of test-
ing a number of the most critical IT and non-IT systems and expect to complete,
in all material respects, testing of all internal systems prior to the year
2000. The Year 2000 Steering Committee will continue to review Year 2000 com-
pliance efforts on an ongoing basis.
 In the third-party evaluation phase, we have identified and contacted
materially significant suppliers of goods or services in an effort to determine
the state of readiness of these important third parties. Materially significant
suppliers for this purpose are considered to be those from whom we purchase a
significant dollar amount of goods or services, those who supply goods or serv-
ices that are critical to uninterrupted production by PPG of its products, in-
cluding those who are sole-source suppliers of important goods or services.
Written assurances that these materially significant suppliers are progressing
toward timely Year 2000 compliance have been received from approximately 66% of
our materially significant suppliers. We are also in the process of identifying
and investigating the Year 2000 readiness of our materially significant custom-
ers. Materially significant customers for this purpose are considered to be
those to which we sell a significant dollar amount of goods.
 If materially significant suppliers or customers or a number of less substan-
tial suppliers or customers do not convert their systems in a timely manner, or
are themselves adversely affected by a lack of Year 2000 readiness on the part
of their suppliers or customers, it could have a material adverse effect on our
operations, liquidity or consolidated financial condition. We believe that our
continuing efforts to gain assurances of Year 2000 compliance from materially
significant suppliers and our investigative efforts with respect to the readi-
ness of materially significant customers will minimize these risks. Nonethe-
less, the actual readiness of these third parties is beyond our control.
 
Costs
The Company is using both internal and external resources to execute its Year
2000 compliance plan. We currently estimate the incremental cost of resolving
the Year 2000 issue at approximately $20 million to $25 million. The incremen-
tal cost of resolving the Year 2000 issue was $7 million in 1998 and was not
material in 1997 or 1996. Approximately 40% to 50% of the total Year 2000 costs
are expected to be expended on equipment or software replacement and the re-
mainder on remediation and testing of existing systems.
 All Year 2000 costs are expected to be funded from the Company's operating
cash flow. We are expensing as incurred all costs related to the assessment,
remediation and testing of the Year 2000 issue, unless new systems or equipment
are purchased. In those instances, such costs will be capitalized and charged
to expense over the useful lives of those assets in accordance with our exist-
ing policy. These cost estimates are based on currently available information,
and may be subject to change.
 
Risks
If needed modifications and conversions of computer systems are not made on a
timely basis by PPG or its materially significant suppliers or customers, the
Company could be affected by business disruption, operational problems, finan-
cial loss, legal liability to third parties and similar risks, any of which
could have a material adverse effect on our consolidated financial condition,
operations or liquidity. Although not anticipated, the most reasonably likely
worst-case scenario of failure by the Company or its key suppliers or custom-
ers to resolve the Year 2000 issue would be a short-term slowdown or cessation
of manufacturing operations at one or more of our facilities and a short-term
inability on the part of the Company to process orders and billings in a timely
manner, and to deliver product to customers.
 
Contingency Planning
While we continue to focus on solutions for Year 2000 issues, and expect to be
Year 2000 compliant in a timely manner, we are in the process of developing a
contingency plan. Such a plan will set forth our responses should PPG or mate-
rially significant third parties with which we have relationships not achieve
Year 2000 compliance in a timely manner. We expect to finalize the contingency
plan by June 30, 1999.
 
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.

                      Management's Discussion and Analysis
- --------------------------------------------------------------------------------
 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 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 foreign currency forward
and option contracts to hedge approximately 30% to 70% of its anticipated net
foreign 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
currencies, it reduces such exposure. The Company does not hedge its foreign
currency 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, 1998 and 1997, 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 adverse changes in the exchange rates of
its outstanding foreign currency hedge contracts of 10% for European currencies
and 20% for Asian and South American currencies would have totaled approxi-
mately $12 million and $5 million as of Dec. 31, 1998 and 1997, respectively.
In addition, PPG had foreign currency denominated debt of $332 million and $405
million as of Dec. 31, 1998 and 1997, respectively. A weakening of the U.S.
dollar relative to this foreign currency denominated debt of 10% for debt de-
nominated in European currencies and 20% for debt denominated in Asian and
South American currencies would have resulted in unrealized translation losses
of approximately $43 million and $52 million as of Dec. 31, 1998 and 1997,
respectively.
 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, 1998 and 1997, the fair value of interest rate swaps was not material.
A 10% increase in interest rates in the United States and a 20% increase in
Asia and South America would have affected PPG's variable rate debt obligations
by increasing interest expense by approximately $3 million as of both Dec. 31,
1998 and 1997. Further, a 10% reduction in interest rates would have increased
the present value of the Company's fixed rate debt by approximately $54 million
and $58 million as of Dec. 31, 1998 and 1997, respectively. Such changes would
not have had 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 values of these
contracts as of Dec. 31, 1998 and 1997, were not material. As a result of a 10%
reduction in the price of natural gas, the Company would have experienced
potential losses in the fair value of the underlying commodity swap and option
contracts as of Dec. 31, 1998 and 1997, of approximately $3 million and $8
million, respectively.

                         Business Segment Information
- -------------------------------------------------------------------------------
 
Segment Organization and Products
Effective in 1998, PPG adopted Statement of Financial Accounting Standards
(SFAS) No. 131, "Disclosures About Segments of an Enterprise and Related In-
formation." SFAS No. 131 establishes standards for reporting information about
operating segments, products and services, geographic areas and major custom-
ers. The presentation of segment information reflects the manner in which man-
agement organizes segments for making operating decisions and assessing per-
formance. Prior year amounts have been restated to conform with the current
presentation format.
 PPG is a multinational manufacturer with three reportable segments: coatings,
glass and chemicals. The Company's segments are organized based on differences
in products. The glass and fiber glass operations have been aggregated into a
single reportable segment. The coatings segment supplies a variety of protec-
tive and decorative coatings and finishes along with adhesives, sealants and
metal pretreatment products for automotive original equipment and aftermarket
refinish, industrial, packaging and architectural applications. In addition to
specific products, the coatings segment supplies technical expertise, engi-
neering and purchasing services to the automotive original and industrial por-
tions of the business. The glass segment supplies flat glass and continuous-
strand fiber glass for residential and commercial construction, automotive
original and replacement markets and other transportation and industrial ap-
plications. The chemicals segment supplies chlor-alkali and specialty
chemicals products. The primary chlor-alkali products are chlorine, caustic
soda, vinyl chloride monomer, chlorinated solvents and chlorinated benzenes.
The primary specialty chemicals products are Transitions(Registered Trademark)
lenses, optical monomers, silicas and fine chemicals. Production facilities and
markets for the coatings and glass segments are predominantly in North America
and Europe, while the chemicals segment operates primarily in North America.
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.
 The accounting policies of the segments are the same as those described in
the summary of significant accounting policies. The Company allocates re-
sources to segments and evaluates the performance of segments based upon re-
ported segment income before interest expense and income, income taxes and mi-
nority interest. Substantially all corporate expenses are allocated to the
segments. Net periodic pension income and expense is allocated to the seg-
ments; however, prepaid pension assets for defined benefit plans that cover
certain U.S. employees are not allocated to the segments and are included in
corporate assets. Intersegment sales and transfers are recorded at selling
prices that approximate market prices.

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, both U.S. and non-
U.S., of which we own more than 50% of the voting stock. Investments in compa-
nies 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
eliminated 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 in accumulated other comprehensive income, 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.
 
Identified intangible assets and goodwill
Identified intangible assets acquired in business combinations accounted for by
the purchase method are recorded based upon fair market value at the date of
acquisition and amortized on a straight-line basis over the estimated useful
lives of the assets (two to 10 years).
 Goodwill, representing the excess of the cost over the net tangible and iden-
tified intangible assets of acquired businesses, is stated at cost and amor-
tized on a straight-line basis over the estimated future periods to be benefit-
ed, principally 20 to 40 years.
 Identified intangible assets and goodwill are reviewed for impairment at each
balance sheet date or whenever events or circumstances indicate that the carry-
ing amounts may not be recoverable.
 
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 13). 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. Pre-
miums 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.
Unrealized gains and losses from option contracts that hedge anticipated trans-
actions are also deferred and recognized in income in the same period as the
hedged transactions. Unrealized gains and losses from forward contracts that
hedge anticipated 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, 1998 and 1997,
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 1998 and 1997, we acquired several businesses, all of which were re-
corded using the purchase method of accounting and, accordingly, the results of
operations of the acquired companies have been included in our consolidated re-
sults from their respective acquisition dates.
 In November and December 1998, respectively, we completed the purchase of the
U.S. architectural coatings business and a portion of the global packaging
coatings business formerly owned by Courtaulds plc (Courtaulds) from Akzo Nobel
N.V. The acquisition of the remaining portion of the Courtaulds global packag-
ing coatings business was substantially completed in early 1999. In September
1998, we acquired the technical coatings business of Orica Ltd. of Melbourne,
Australia. The purchase included Orica's automotive refinish, automotive origi-
nal equipment, coil, packaging and industrial coatings businesses. The purchase
of certain Orica assets that are currently leased is expected to be completed
in 1999. In February 1998, we acquired the automotive coatings business of He-
lios-Lacke Bollig & Kemper GmbH & Co. KG of Cologne, Germany. In January 1998,
we acquired the assets of an automotive glass plant in Evart, Mich., from
Chrysler Corporation. The preliminary purchase price allocations for the acqui-
sitions occurring in the second half of 1998 and used in preparing the Dec. 31,
1998, balance sheet are subject to adjustment in 1999 when finalized.
 From September to December 1997, we acquired the U.S. industrial pretreatment
business of Man-Gill Chemical Company; Max Meyer Duco S.p.A. (Max Meyer), a Eu-
ropean supplier of automotive refinish, fleet finish and decorative coatings;
Phillips Paint Products, a Canadian industrial coatings manufacturer; the
worldwide packaging coatings businesses of BASF Lacke + Farben AG; Keeler &
Long, a U.S. manufacturer of high-performance coatings and coil coatings, and
Sipsy Chimie Fine S.C.A., a French manufacturer of pharmaceutical intermediates
formerly owned by Warner Lambert Company. We also increased our ownership in-
terest in 1997 in two related automotive original coatings companies located in
Brazil and Argentina from 45% to 100%.
 The cost of the 1998 and 1997 acquisitions was $390 million and $363 million,
respectively, plus the assumption of indebtedness of $11 million and $42 mil-
lion, respectively.
 On a pro forma basis, if the 1998 acquisitions had occurred effective Jan. 1,
1997, and the 1997 acquisitions had occurred effective Jan. 1, 1996, they would
have contributed net sales of approximately $280 million in 1998, $635 million
in 1997, and $300 million in 1996. The pro forma impact of these acquisitions
on net income and earnings per common share in 1998, 1997 and 1996 is accretive
but is not material. The pro forma financial information is not necessarily in-
dicative of the operating results that would have occurred had the acquisitions
been consummated as of the dates indicated, nor are they necessarily indicative
of future operating results.
 In July 1998, we completed the sale of our European flat and automotive glass
businesses to Glaverbel S.A. of Brussels, Belgium, for $266 million in cash
plus the assumption of certain indebtedness, which resulted in a pre-tax gain
of approximately $85 million. We also completed certain business divestitures
in 1997, primarily the sale of the surfactants business, which resulted in a
net pre-tax gain of $58 million. The net sales of these divested businesses to-
taled $271 million in 1998, $550 million in 1997 and $593 million in 1996. Ad-
ditionally, in August 1998, we sold the European decorative coatings business
acquired in the 1997 Max Meyer acquisition. The selling price approximated the
carrying value of the net assets sold.
 During 1998, we approved a restructuring plan principally associated with cost
reduction initiatives in our glass and coatings operations. We recorded a pre-
tax charge of $19 million in connection with this plan. The components of the
plan include severance benefits for 283 employees. As of Dec. 31, 1998, $2 mil-
lion had been paid under the plan and it is anticipated that the remainder will
be paid in 1999. We also recorded in 1998 an additional pre-tax charge of $15
million related to the disposition of our equity interests in two Asian float
glass plants and two Asian downstream fabrication facilities. The $15 million
pre-tax charge related to a reassessment of the proceeds expected to be real-
ized on the dispositions of $14 million and asset write-offs of $1 million. Ad-
ditionally, in 1998 we recorded a $3 million reversal

of a reserve, originally recorded in 1997, related to the closure of our Perry,
Ga., flat glass plant.
 In 1997 we recorded a pre-tax restructuring charge of $102 million related to
certain glass businesses that were not meeting strategic and performance objec-
tives. The principal components of the 1997 restructuring program included the
closure of our Perry, Ga., flat glass plant and the disposition of our equity
interests in two Asian float glass plants. The pre-tax restructuring charge in
1997 included $61 million of asset write-offs and $41 million associated with
cash outlays primarily for severance costs (317 employees), a proportionate
share of equity investee indebtedness, and demolition and environmental costs,
net of estimated proceeds from sale. During 1998, cash outlays associated with
both the 1997 restructuring program and the additional restructuring charge re-
corded in 1998 related to this program totaled $11 million. We also reversed $3
million of the 1997 restructuring charge in 1998. It is anticipated that the
remaining reserves related to the 1997 restructuring program of $41 million at
Dec. 31, 1998, will be paid in 1999.

million. Of these credit lines, $800 million will expire in December 2001 and
requires 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 and Canada. The remaining $25 million, relating to a subsidiary,
will expire in September 1999 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,
1998, we had used $21 million of these lines of credit.
 Our non-U.S. operations have other committed and uncommitted lines of credit
totaling $43 million and $449 million, respectively, of which $26 million and
$140 million, respectively, were used at Dec. 31, 1998. The committed lines of
credit, which expire between 1999 and 2001, do not require significant commit-
ment 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, 1998 and 1997, balances for "Short-term debt and current portion
of long-term debt" include, respectively, $147 million and $34 million of com-
mercial paper and $325 million and $354 million of short-term notes. The
weighted-average interest rates of short-term borrowings as of Dec. 31, 1998
and 1997, were 5.1% and 6.0%, respectively.
 Interest payments in 1998, 1997 and 1996 totaled $121 million, $106 million
and $109 million, respectively.
 Rental expense for operating leases was $75 million, $70 million and $68 mil-
lion in 1998, 1997 and 1996, respectively. Minimum lease commitments for oper-
ating leases that have initial or remaining lease terms in excess of one year
at Dec. 31, 1998, are (in millions) $38 in 1999, $25 in 2000, $14 in 2001, $8
in 2002, $5 in 2003 and $21 thereafter.
 
6. 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
$1,212 million and $1,317 million, respectively, at Dec. 31, 1998. The corre-
sponding amounts at Dec. 31, 1997, were $1,272 million and $1,362 million, re-
spectively. The fair values of the other instruments approximated their carry-
ing 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.

</TABLE>
 
 Dispositions of certain non-U.S. subsidiaries in 1997 generated U.S. capital
losses of approximately $180 million. A portion of these losses was realized
by offsetting it against capital gains from previous years and a 1997 capital
gain from the sale of certain U.S. businesses. The remaining $88 million capi-
tal loss carryforward was offset with a valuation allowance at Dec. 31, 1997,
because PPG's ability to realize the amount carried forward was uncertain. In
July 1998, PPG recognized a gain from the sale of its European flat and auto-
motive glass businesses, of which a considerable portion was capital, the tax
on which was offset by the capital loss carryforward. As a result of the real-
ization of the tax benefit from the capital loss carryforward, the valuation
allowance that was recorded in the prior year was reversed in 1998. This bene-
fit from the realization of the capital loss in both 1997 and 1998 reduced the
effective tax rate in each year.
 At Dec. 31, 1998, subsidiaries of the Company had available net operating
loss (NOL) carryforwards of approximately $129 million for income tax purpos-
es, of which $104 million has an indefinite expiration. The remaining $25 mil-
lion expires between the years 1999 and 2003.
 The majority of the NOL carryforwards relate to operations of subsidiaries in
countries permitting indefinite carryforward of losses. Generally, a valuation
allowance has been established for these carryforwards because the ability to
utilize them is uncertain.
 Income before income taxes of our non-U.S. operations for 1998, 1997 and 1996
was $273 million, $232 million and $266 million, respectively.
 No deferred U.S. income taxes have been provided on certain undistributed
earnings of non-U.S. subsidiaries, which amounted to $681 million at Dec. 31,
1998, and $495 million at Dec. 31, 1997. 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
liability on these earnings.
 The Internal Revenue Service has examined our U.S. federal income tax returns
through 1993, and we have paid all tax claims.
 Income tax payments in 1998, 1997 and 1996 totaled $385 million, $452 million
and $402 million, respectively.
 
9. Pensions and Other Postretirement Benefits
We have noncontributory defined benefit pension plans that cover certain em-
ployees worldwide. PPG also sponsors defined benefit plans that provide medi-
cal and life insurance benefits for certain active and retired U.S. and Cana-
dian employees and dependents. Salaried and certain wage employees hired after
Jan. 31, 1993, will not be entitled to postretirement medical benefits. At
Dec. 31, 1998 and 1997, the U.S. plans had provisions that capped the cost of
postretirement medical benefits at 2003 levels for certain current and future
retirees covered by bargaining plans and non-bargaining plans.

 The following weighted average assumptions were used to determine the benefit
obligations and net periodic benefit cost (income) for our defined benefit pen-
sion and other postretirement benefit plans:

 The weighted-average healthcare cost trend rate used was 7% for 1998 and 6.7%
for 1999, declining ratably to 3.5% in the year 2007. If these trend rates were
increased or decreased by one percentage point per year, such increases or de-
creases would have the following effects:

 The Company also incurred costs for multi-employer pension plans of $1 million
in each of the years 1998, 1997 and 1996. Multi-employer healthcare costs to-
taled $1 million in each of the years 1998, 1997 and 1996.
 
10. Commitments and Contingent Liabilities
PPG is involved in a number of lawsuits and claims, both actual and potential,
including some that it has asserted against others, in which substantial money
damages are sought. These lawsuits and claims relate to product liability, con-
tract, patent, environmental, antitrust and other matters arising out of the
conduct of PPG's business. The Company has been named in a number of antitrust
lawsuits alleging that PPG acted with competitors to fix prices and allocate
markets for certain glass products. These antitrust proceedings are in an early
stage. 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, in the aggregate, the outcome
of all lawsuits and claims involving PPG 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, 1998 and
1997, PPG had reserves for environmental contingencies totaling $94 million and
$100 million, respectively. Pre-tax charges against income for environmental
remediation costs in 1998, 1997 and 1996 totaled $10 million, $34 million and
$27 million, respectively, and are included in "Other charges" in the statement
of income. Cash outlays related to such charges aggregated $16 million, $25
million and $36 million in 1998, 1997 and 1996, 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
significant portion of such exposure involves three operating plant sites.
Initial remedial actions are occurring at these sites. Studies 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 exposure 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

                                     Notes
- --------------------------------------------------------------------------------
contributions of wastes to such sites. PPG is generally not a major 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.
 
11. 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; 600
million shares are authorized and 290,573,068 were issued at Dec. 31, 1998,
1997 and 1996. Shares outstanding at Dec. 31, 1998 and 1997, exclude unreleased
new ESOP shares (see Note 13).
 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 would generally be 50% of the respective stocks' current
fair market value.
 Treasury shares held at Dec. 31, 1998 and 1997, were 115,448,529 shares and
112,518,245 shares, respectively. Purchases of treasury stock totaled
3,793,300, 5,964,792 and 12,452,817 in 1998, 1997 and 1996, respectively. Issu-
ances of treasury stock totaled 863,016, 804,507 and 1,217,958 in 1998, 1997
and 1996, respectively.
 Per share cash dividends paid were $1.42 in 1998, $1.33 in 1997 and $1.26 in
1996.

 Foreign currency translation adjustments exclude income tax expense (benefit)
given that the earnings of non-U.S. subsidiaries are deemed to be reinvested
for an indefinite period of time. The tax benefit associated with the minimum
pension liability adjustment was $3 million in 1998 and $8 million in 1997.
 
13. 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-
pants' 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
347,287, 471,526 and 506,761 shares of PPG common stock (new ESOP shares) on
the open market in 1998, 1997 and 1996, 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 5).
 Compensation expense related to the ESOP for 1998, 1997 and 1996 totaled $9
million, $11 million and $15 million, respectively. Interest expense totaled
$10 million, $11 million and $11 million for 1998, 1997 and 1996, respectively.
Dividends on PPG shares held by the ESOP, to service ESOP debt, totaled $39
million, $39 million and $37 million for 1998, 1997 and 1996, respectively. The
fair value of unreleased new ESOP shares was $8 million and $13 million at Dec.
31, 1998 and 1997, respectively. Shares held by the ESOP as of Dec. 31, 1998
and 1997, are as follows:

from equity affiliates were $16 million, $14 million and $15 million in 1998,
1997 and 1996, respectively.
 
15. Stock Option Plans
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 8,808,178 and
10,029,300 at Dec. 31, 1998 and 1997, respectively.
 On July 1, 1998, the Company granted to substantially all active employees of
the Company and its majority owned subsidiaries, subject to statutory and regu-
latory requirements, including but not limited to approvals required by securi-
ties and labor laws, the option to purchase 100 shares of common stock at its
then fair market value of $70 per share. Options are exercisable beginning July
1, 2003 and expire on June 30, 2008. If the Company's earnings per common share
for the year ended Dec. 31, 2000 is $7.00 or more, the options become exercis-
able beginning Jan. 31, 2001.
 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 1998, 1997 and 1996 consistent with the methodology pre-
scribed in SFAS No. 123, "Accounting for Stock-Based Compensation," net income
and earnings per common share, assuming dilution, would have been reduced by
$24 million and $0.13 in 1998, $20 million and $0.11 in 1997 and $16 million
and $.09 in 1996. 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.

</TABLE>
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 split
payable on June 10, 1994.
(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.
