                                 USG CORPORATION


MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND FINANCIAL
CONDITION

Overview

1997 was an excellent year for USG Corporation.  Strong  operating  results were
realized by all of USG's  businesses.  Increased  demand led to record levels of
shipments  for all major  product  lines.  In pursuit  of its goal of  improving
financial flexibility, USG achieved its debt reduction objective and was awarded
an investment grade BBB rating by Standard & Poor's.  Significant  progress also
was made toward the Corporation's  strategic  objectives of investing for growth
and maintaining operational excellence.

USG continues to report EBITDA (earnings before interest,  taxes,  depreciation,
depletion,  amortization and certain other income and expense items) as a result
of its financial  restructuring  in 1993 and the  restructuring's  effect (i.e.,
fresh start accounting  charges) on financial  reporting  through  September 30,
1997.  While EBITDA is primarily  used to facilitate  comparisons of current and
historical  results, it can also be helpful in understanding cash flow generated
from  operations  that  is  available  for  taxes,   debt  service  and  capital
expenditures.  However,  EBITDA  should not be  considered  by  investors  as an
alternative  to net  earnings as an  indicator  of the  Corporation's  operating
performance or to cash flows as a measure of its overall liquidity.

Results of Operations

Consolidated  Results. A bar chart entitled "Net Sales (millions of dollars)" on
page 19 of the Annual Report to Stockholders shows that for the years 1995, 1996
and 1997  (shown on the  x-axis)  the  Corporation  had net sales  (shown on the
y-axis) of $2,444 million,  $2,590 million and $2,874 million,  respectively.  A
bar chart  entitled  "EBITDA  (millions  of  dollars)"  on page 19 of the Annual
Report to  Stockholders  shows that for the years 1995,  1996 and 1997 (shown on
the x-axis) the  Corporation  had EBITDA  (shown on the y-axis) of $417 million,
$437 million and $572 million, respectively.

Net sales of $2,874 million in 1997  represented the sixth  consecutive  year of
improved  sales and an  increase  of $284  million,  or 11%,  over 1996.  EBITDA
increased for the fifth  consecutive  year,  amounting to $572 million,  up $135
million,  or 31%, from 1996. The strong results in 1997 were attributable to (i)
records for average  selling  price and  shipments  of  SHEETROCK  brand  gypsum
wallboard  (ii) record  sales of ceiling  tile and DONN  ceiling  grid and (iii)
record  shipments of SHEETROCK  joint compound and DUROCK cement board. In 1996,
net sales were up 6%, while EBITDA increased 5% versus 1995.

Gross profit as a percentage of net sales was 27.4% in 1997, compared with 24.9%
in 1996,  and 24.7% in 1995.  Gross  profit in 1996 was  lowered by a $7 million
provision  to cost of products  sold  associated  with  actions  implemented  to
improve the operating efficiencies of USG's European businesses.

In 1997, USG began modifying its computer-based systems that are affected by the
year  2000  date  change.  Anticipated  spending  for this  modification  is not
expected  to have a  material  impact on the  Corporation's  ongoing  results of
operations.

Selling  and  administrative  expenses  of $281  million in 1997  increased  $13
million, or 5%, over 1996. Expenses of $268 million in 1996 were up $24 million,
or 10%, compared with 1995. The increase for each year primarily reflects higher
levels of expenses  related to  incentive  compensation  and benefits as well as
costs to consolidate and upgrade customer  service  functions for the gypsum and
ceilings  businesses.  As a percent of net  sales,  selling  and  administrative
expenses were 9.8% in 1997, 10.3% in 1996 and 10.0% in 1995.

The noncash,  no-tax-impact  amortization of excess reorganization value reduced
operating profit by $127 million in 1997 and by $169 million in each of 1996 and
1995. Excess  reorganization value was established in connection with USG's 1993
financial  restructuring  that was accounted  for using the  principles of fresh
start accounting. Excess reorganization value was scheduled to be amortized over
a five-year  period through April 1998.  However,  as of September 30, 1997, the
remaining  balance of $83 million was offset by the  elimination  of a valuation
allowance. See "Note 8. Income Taxes" for additional information.

Interest  expense  continued  to decline in 1997 as a result of debt  reduction.
Interest expense of $60 million in 1997 was down 20% from 1996. Interest expense
of $75 million in 1996 declined 24% from the 1995 level of $99 million.

In 1995, the Corporation  recorded a $30 million pretax ($24 million  after-tax)
charge in connection with the disposal of its insulation manufacturing business.
This charge is reflected in other expense, net in the Consolidated  Statement of
Earnings. See "Note 7. Writedown of Assets" for additional information.

The  Corporation's  income tax  expense  is  computed  based on pretax  earnings
excluding the noncash amortization of excess  reorganization value, which is not
deductible for federal income tax purposes. In 1997, income tax expense amounted
to $172 million, compared with $117 million in 1996 and $97 million in 1995. The
Corporation's  effective tax rates for 1997, 1996 and 1995 were 53.9%, 88.9% and
149.0%, respectively.  Excluding the amortization of excess reorganization value
and, in 1995, a $15 million write-off of excess  reorganization value associated
with the writedown of the insulation business,  the Corporation's 1997, 1996 and
1995 effective tax rates were 38.6%, 38.9% and 39.0%, respectively. See "Note 8.
Income Taxes" for additional information.

USG's reported net earnings in 1997 were $148 million,  and diluted earnings per
share were $3.03. These earnings were net of the noncash  amortization of excess
reorganization value of $127 million, or $2.60 per diluted share.

In 1996, reported net earnings amounted to $15 million, and diluted earnings per
share were $0.31.  These  earnings were net of (i) the noncash  amortization  of
excess reorganization value of $169 million and (ii) the noncash amortization of
reorganization  debt  discount  of $1  million  included  in  interest  expense.
Together,  these items reduced 1996 net earnings by $170  million,  or $3.58 per
diluted share.

In 1995,  USG  reported a net loss of $32 million and a loss per share of $0.71.
This loss included (i) the noncash  amortization of excess  reorganization value
of $169 million (ii) the noncash amortization of reorganization debt discount of
$4 million  included  in interest  expense  and (iii) the $24 million  after-tax
writedown of the  insulation  business.  Together,  these items reduced 1995 net
earnings by $197 million, or $4.37 per share.


Market  Conditions  and Outlook.  Based on  preliminary  data issued by the U.S.
Bureau of the Census,  U.S. housing starts were an estimated 1.474 million units
in 1997.  Housing  starts  totaled 1.477 million units in 1996 and 1.354 million
units in 1995.  Despite the virtually  unchanged level of housing starts in 1997
as compared  with 1996,  the U.S.  wallboard  market  continued to grow in 1997.
Record U.S. industry  shipments of wallboard were up 3% versus 1996, due in part
to very strong demand from  remodeling and  nonresidential  markets.  Repair and
remodel activity  continued its upward trend in 1997. As for new  nonresidential
construction,  the finishing of nonresidential interiors follows contract awards
by as much as a year. As a result,  demand from this market improved in 1997 due
to a 1%  increase  in U.S.  nonresidential  construction  in 1996 versus 1995 as
measured in floor space for which contracts were awarded.

Barring  any major  change in the U.S.  economy,  new  residential  construction
should continue at a relatively high level in 1998. Demand for USG products from
both  residential  and  nonresidential  repair and  remodeling  is  expected  to
continue its upward trend in 1998. Nonresidential  construction rose 10% in 1997
as compared with 1996.  This increase should be beneficial to USG in 1998 due to
the lag in the  finishing  of  nonresidential  interiors  of  roughly  one year.
Construction  activity in Canada and Mexico is expected to maintain the recovery
begun in 1997.  USG's  exposure to markets  outside  North  America is primarily
concentrated  in Europe but also includes  sales to Asia and Latin  America.  We
anticipate  that demand in Eastern  Europe and Latin  America  will  continue to
grow, while  conditions in Western Europe will remain stable.  The prospects for
Asian construction  markets are not good, but USG's presence there is relatively
minor.

North American Gypsum. A bar chart entitled "Net Sales (millions of dollars)" on
page 21 of the Annual Report to Stockholders shows that for the years 1995, 1996
and 1997 (shown on the x-axis) North American Gypsum had net sales (shown on the
y-axis) of $1,924 million,  $2,067 million and $2,338 million,  respectively.  A
bar chart  entitled  "EBITDA  (millions  of  dollars)"  on page 21 of the Annual
Report to  Stockholders  shows that for the years 1995,  1996 and 1997 (shown on
the  x-axis)  North  American  Gypsum had EBITDA  (shown on the  y-axis) of $386
million, $417 million and $539 million, respectively.

Net sales of $2,338 million in 1997 were up $271 million,  or 13%, and EBITDA of
$539 million rose $122 million,  or 29%, compared with 1996. For 1996, net sales
of $2,067 million  increased  $143 million,  or 7%, while EBITDA of $417 million
increased $31 million, or 8%, over 1995.

Strong  results in 1997 for  United  States  Gypsum  Company  primarily  reflect
records for average  price and  shipments of  SHEETROCK  gypsum  wallboard.  The
average  selling  price of SHEETROCK  wallboard in 1997 was $122.65 per thousand
square feet, up 11% compared with the 1996 average price of $110.56. The average
price in 1995 was $110.44.  Shipments of SHEETROCK wallboard totaled 8.4 billion
square  feet,  compared  with 8.0  billion  square  feet in 1996 and 7.6 billion
square feet in 1995.  In addition,  shipments of  SHEETROCK  joint  compound and
DUROCK cement board also set records in 1997. U.S. Gypsum's  manufacturing costs
for SHEETROCK  wallboard  were down  slightly in 1997 due to improved  operating
efficiencies  resulting  from  cost-reduction  projects  implemented in 1996 and
1997. Comparing 1996 with 1995, lower furnish prices for wastepaper, the primary
raw  material of  wallboard  paper,  resulted in a 4% decrease in  manufacturing
costs. U.S.  Gypsum's plants operated at 99% of capacity in 1997,  compared with
the estimated average rate of 96% for the U.S. industry.  In 1996, U.S. Gypsum's
plants operated at 94% of capacity.

L&W Supply Corporation,  USG's building products distribution business, reported
record net sales in 1997 due to record  shipments of wallboard  and record sales
of   complementary   building   materials.   EBITDA  for  L&W  Supply   improved
significantly  in each of the  past  three  years as a  result  of gross  profit
improvements  for all of its product lines.  As of December 31, 1997, L&W Supply
operated a total of 176 locations in the United States.

CGC Inc.'s  gypsum  business  experienced  improved net sales and EBITDA in both
1997 and 1996 primarily due to stronger domestic shipments in eastern Canada and
exports to the United States.

Worldwide  Ceilings.  A bar chart entitled "Net Sales  (millions of dollars)" on
page 22 of the Annual Report to Stockholders shows that for the years 1995, 1996
and 1997 (shown on the x-axis)  Worldwide  Ceilings  had net sales (shown on the
y-axis) of $609  million,  $612 million and $634  million,  respectively.  A bar
chart entitled "EBITDA (millions of dollars)" on page 22 of the Annual Report to
Stockholders  shows that for the years 1995, 1996 and 1997 (shown on the x-axis)
Worldwide Ceilings had EBITDA (shown on the y-axis) of $67 million,  $58 million
and $81 million, respectively.

Net sales of $634 million in 1997 were up $22 million,  or 4%, and EBITDA of $81
million increased $23 million,  or 40%,  compared with 1996.  Adjusting for a $7
million  charge  taken  in 1996 to  improve  operating  efficiencies  for  USG's
European  businesses,  EBITDA in 1997  increased  25%. The increase in net sales
reflects record sales of ceiling tile and DONN ceiling grid.  These records were
attributable  to  strong  demand  in the U.S.  nonresidential  market  (both new
construction and renovation) and growing  international  demand.  EBITDA in 1997
was favorably affected by higher volume and prices,  reduced manufacturing costs
and improved international  operating  efficiencies.  USG's international sales,
which are primarily concentrated in Europe, have not been materially affected by
recent economic events in Asia.

Net sales in 1996 for Worldwide  Ceilings  rose slightly to $612 million,  while
EBITDA of $58 million fell $9 million,  or 13%, compared with 1995. The slightly
higher sales in 1996 reflect record  shipments of ceiling tile at higher average
selling prices and increased  shipments of ceiling grid. These improvements were
partially  offset by the absence of  full-year  results for the U.S.  insulation
manufacturing  business  that was sold in April 1996.  The lower level of EBITDA
was primarily attributable to (i) a $7 million provision associated with actions
implemented to improve the operating  efficiencies of USG's European  businesses
(ii) expenses  associated  with  enhancing  customer  service  systems and (iii)
start-up  costs  related to a new ceiling tile line placed in service in 1996 at
the Greenville, Miss., plant.


Liquidity and Capital Resources

Following  its 1993  financial  restructuring,  USG was  engaged in a  financial
strategy of reducing  debt and growing  its gypsum,  ceilings  and  distribution
businesses  through  a  balanced  application  of free cash  flow  between  debt
reduction and capital  expenditures.  Two  objectives of this strategy  involved
reaching a target debt level of $650 million  within five years and achieving an
investment grade rating on its capital structure.

As of December 31, 1997,  total debt amounted to $620 million,  reflecting a net
reduction  since  May  1993 of $936  million.  In the  fourth  quarter  of 1997,
Standard & Poor's raised its rating of USG's debt to investment grade BBB. As of
December  31,  1997,  Moody's  rating  of USG  debt  was Ba1,  one  level  below
investment grade.  Going forward,  USG's financial  strategy will be to increase
the proportion of free cash flow it spends on capital projects,  while reviewing
possible applications of its cash for other corporate purposes.

A bar chart  entitled "Debt  Principal  (millions of dollars)" on page 23 of the
Annual Report to Stockholders  shows that as of December 31, 1995, 1996 and 1997
(shown on the x- axis) the  Corporation's  principal amount of total debt (shown
on the y-axis) was $926 million, $772 million and $620 million,  respectively. A
bar chart entitled  "Capital  Spending  (millions of dollars)" on page 23 of the
Annual  Report to  Stockholders  shows  that for the years  1995,  1996 and 1997
(shown on the x-axis) the Corporation had capital spending (shown on the y-axis)
of $147 million, $120 million and $172 million, respectively.

Debt Reduction.  In 1997, total debt was reduced $152 million,  or 20%, from the
December 31, 1996, total of $772 million.  Debt repayments during 1997 primarily
consisted  of $85 million of revolving  bank loans,  $48 million of 8.75% senior
debentures  due  2017  and $41  million  of 8%  senior  notes  due  1997.  These
repayments  were partially  offset by increased  borrowing on the  Corporation's
Canadian credit facility.

Capital  Expenditures.  Capital  expenditures  amounted to $172 million in 1997,
compared with $120 million in 1996. As of December 31, 1997,  the  Corporation's
capital expenditure commitments for the replacement, modernization and expansion
of  operations  amounted  to $363  million,  compared  with $173  million  as of
December 31, 1996.

In the North American Gypsum business,  ground was broken in June 1997 for a new
$110 million plant in Bridgeport,  Ala. This facility will manufacture SHEETROCK
brand wallboard  using 100% synthetic  gypsum and is expected to begin operation
in mid-1999.  Construction is also under way to build a $90 million  facility to
manufacture  gypsum  wood  fiber  panels at the  Gypsum,  Ohio,  plant.  The new
production line is expected to begin operating by the end of 1999. Complementing
this  investment  in the gypsum wood fiber  business  was the  acquisition  of a
gypsum fiber panel plant in Port Hawkesbury,  Nova Scotia,  in late 1997. Gypsum
wood fiber  products  manufactured  at these  plants will be marketed  under the
FIBEROCK  brand name.  In October 1997,  USG  announced  that it will invest $90
million to rebuild and modernize its  wallboard  manufacturing  line at the East
Chicago,  Ind., plant. This new line is also expected to begin production by the
end of 1999.  Additional  capital  investments  in 1997 included  cost-reduction
projects such as the  installation of stock cleaning  equipment to utilize lower
grades of recycled paper and the  installation  of processes to accommodate  the
use of synthetic gypsum at manufacturing  facilities where it is more economical
than natural sources of gypsum rock.

In the Worldwide  Ceilings  business,  construction began in early 1997 on a $35
million project that includes the  replacement of two old production  lines with
one modern,  high-speed  line at the ceiling tile plant in Cloquet,  Minn.  This
project will be completed by mid-1998.


The Corporation  periodically  evaluates  possible  acquisitions or combinations
involving other businesses or companies in industries and markets related to its
current  operations.  The Corporation  believes that its available  liquidity is
generally  adequate  to  support  most  opportunities  and that it has access to
additional financial resources to take advantage of other opportunities.


Working Capital. Working capital (current assets less current liabilities) as of
December 31, 1997, amounted to $264 million,  and the ratio of current assets to
current  liabilities was 1.7 to 1. As of December 31, 1996,  working capital was
$159 million,  and the ratio of current assets to current liabilities was 1.4 to
1.

Cash and cash  equivalents  as of December  31,  1997,  amounted to $72 million,
compared with $44 million as of December 31, 1996.  This increase  reflects 1997
net cash flows from operating  activities of $332 million,  partially  offset by
net cash flows to investing  and  financing  activities of $170 million and $134
million,  respectively.  Receivables  (net of reserves)  were $297 million as of
December 31, 1997, up from $274 million as of year-end 1996,  while  inventories
increased to $208 million from $185 million,  and accounts  payable rose to $146
million from $141 million. These increases reflect the greater level of business
in 1997.


Available Liquidity.  The Corporation has additional liquidity available through
several  financing  arrangements.  Revolving  credit  facilities  in the  United
States,  Canada and Europe allow the Corporation to borrow up to an aggregate of
$611  million  (including  a $125 million  letter of credit  subfacility  in the
United  States),  under which,  as of December 31, 1997,  outstanding  revolving
loans totaled $97 million and letters of credit issued and outstanding  amounted
to $84 million,  leaving the Corporation with $430 million of available  credit.
The Corporation had additional  borrowing capacity of $50 million as of December
31, 1997, under a revolving accounts receivable facility (see "Note 3. Financing
Arrangements").  A shelf  registration  statement  filed with the Securities and
Exchange  Commission  allows  the  Corporation  to offer  from time to time debt
securities,  shares of preferred and common stock or warrants to purchase shares
of common stock,  all having an aggregate  initial  offering price not to exceed
$300 million.  As of the filing date of the Corporation's  1997 Annual Report on
Form 10-K, no securities had been issued pursuant to this registration.


Legal Contingencies.  One of the Corporation's  subsidiaries,  U.S. Gypsum, is a
defendant  in asbestos  lawsuits  alleging  both  property  damage and  personal
injury.  See "Note 16.  Litigation"  for  information  concerning  the  asbestos
litigation.

The Corporation and certain of its subsidiaries  have been notified by state and
federal  environmental  protection  agencies of possible  involvement  as one of
numerous "potentially  responsible parties" in a number of so-called "Superfund"
sites in the United States. The Corporation  believes that neither these matters
nor any other known governmental proceeding regarding environmental matters will
have a material  adverse  effect  upon its  earnings or  consolidated  financial
position.  See "Note 16. Litigation" for additional information on environmental
litigation.

                                 USG CORPORATION
                          NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies

Nature  of  Operations.  Through  its   subsidiaries,   USG   Corporation   (the
"Corporation") is a leading  manufacturer and distributor of building materials,
producing  a  wide  range  of  products   for  use  in  new   residential,   new
nonresidential and repair and remodel construction,  as well as products used in
certain industrial  processes.  The Corporation's  operations are organized into
two core  businesses:  North American  Gypsum,  which  manufactures  and markets
gypsum wallboard and related  products in the United States,  Canada and Mexico,
and Worldwide  Ceilings,  which  manufactures and markets ceiling tile,  ceiling
grid and other interior systems products worldwide.  Distribution is carried out
through L&W Supply  Corporation,  a wholly owned  subsidiary of the Corporation;
building  materials  dealers;  home  improvement  centers  and other  retailers;
specialty wallboard distributors; and contractors.

Consolidation. The consolidated financial statements include the accounts of the
Corporation  and its  subsidiaries.  All significant  intercompany  balances and
transactions are eliminated in consolidation.

Use of Estimates.  The  preparation of financial  statements in conformity  with
generally accepted  accounting  principles requires management to make estimates
and assumptions.  These estimates and assumptions affect the reported amounts of
assets,  liabilities,  revenues and expenses.  Actual  results could differ from
these estimates.

Reclassifications.  Certain amounts in the prior years' financial statements and
notes thereto have been reclassified to conform with the 1997 presentation.

Revenue  Recognition.  The Corporation  recognizes  revenue upon the shipment of
products.

Cash and Cash Equivalents.  Cash and cash equivalents  primarily consist of time
deposits with original maturities of three months or less.

Inventory Valuation.  Most of the Corporation's  domestic inventories are valued
under the last-in,  first-out  ("LIFO")  method.  The remaining  inventories are
stated at the lower of cost or market under the first-in,  first-out ("FIFO") or
average  production  cost  methods.  Inventories  include  material,  labor  and
applicable factory overhead costs.

Property, Plant and Equipment. Property, plant and equipment are stated at cost,
except for those assets that were revalued  under fresh start  accounting in May
1993.  Provisions  for  depreciation  of  property,   plant  and  equipment  are
determined principally on a straight-line basis over the expected average useful
lives of composite asset groups.  Depletion is computed on a basis calculated to
spread  the cost of gypsum and other  applicable  resources  over the  estimated
quantities of material recoverable.

Excess  Reorganization  Value.  In the third quarter of 1997,  the remaining $83
million balance of excess  reorganization  value was  eliminated.  This balance,
which  would  have  been  amortized  through  April  1998,  was  offset  by  the
elimination  of a valuation  allowance  in  accordance  with AICPA  Statement of
Position  90-7,  "Financial  Reporting by Entities in  Reorganization  Under the
Bankruptcy  Code"  ("SOP  90-7").  See "Note 8.  Income  Taxes"  for  additional
information.  Excess  reorganization value totaling $851 million was recorded in
1993 in connection with a comprehensive restructuring of the Corporation's debt.
The Corporation  accounted for the  restructuring  using the principles of fresh
start  accounting  as  required  by SOP 90- 7.  Pursuant  to  these  principles,
individual  assets and  liabilities  were adjusted to fair market value.  Excess
reorganization   value  was  the  portion  of  the   reorganization   value  not
attributable to specific assets.

Goodwill.  Goodwill is  amortized on a  straight-line  basis over a period of 40
years. On a periodic basis,  the Corporation  estimates the future  undiscounted
cash flows of the businesses to which  goodwill  relates in order to ensure that
the carrying  value of goodwill has not been  impaired.  Goodwill is included in
other assets on the Consolidated Balance Sheet.

Financial  Instruments.  The Corporation  uses derivative  instruments to manage
well-defined  interest rate,  energy cost and foreign  currency  exposures.  The
Corporation  does not use  derivative  instruments  for  trading  purposes.  The
criteria used to determine if hedge accounting  treatment is appropriate are (i)
the  designation  of the hedge to an  underlying  exposure  (ii)  whether or not
overall uncertainty is being reduced and (iii) if there is a correlation between
the value of the derivative instrument and the underlying obligation.

Interest Rate Derivative  Instruments:  The Corporation  utilizes  interest rate
swap  agreements to manage the impact of interest rate changes on its underlying
floating-rate  debt.  These  agreements are designated as hedges and qualify for
hedge accounting.  Amounts payable or receivable under these swap agreements are
accrued as an increase or decrease to interest  expense on a current  basis.  To
the  extent  the  underlying  floating-rate  debt is  reduced,  the  Corporation
terminates  swap  agreements  accordingly  so as  not  to  be  in an  overhedged
position.  In such cases, the Corporation  recognizes gains and/or losses in the
period the agreement is terminated.

Energy  Derivative  Instruments:  The Corporation  uses swap agreements to hedge
anticipated purchases of fuel to be utilized in the manufacturing  processes for
gypsum wallboard and ceiling tile. Under these swap agreements,  the Corporation
receives or makes payments based on the  differential  between a specified price
and the actual  closing  price for the current  month's  energy price  contract.
These  contracts  are  designated  as hedges and qualify  for hedge  accounting.
Amounts  payable or  receivable  under these swap  agreements  are accrued as an
increase or decrease to cost of products sold, along with the actual spot energy
cost of the corresponding underlying hedge transaction, the combination of which
amounts to the predetermined specified contract price.

Foreign  Exchange  Derivative  Instruments:  The Corporation has operations in a
number of  countries  and has  intercompany  transactions  among them and,  as a
result,   is  exposed  to  changes  in  foreign  currency  exchange  rates.  The
Corporation  manages  these  exposures  on a  consolidated  basis,  which allows
netting of certain  exposures to take advantage of any natural  offsets.  To the
extent the net exposures are hedged,  forward  contracts are used.  Gains and/or
losses on these  foreign  currency  hedges are  included in net  earnings in the
period in which the exchange rates change.

Foreign  Currency  Translation.  Net  currency  translation  gains or  losses on
foreign subsidiaries are included in deferred currency translation,  a component
of stockholders' equity.

Research and Development.  Research and development  expenditures are charged to
earnings as incurred and amounted to $19 million, $19 million and $18 million in
the years ended December 31, 1997, 1996 and 1995, respectively.

2.  Earnings Per Share

     In accordance with Statement of Financial Accounting Standards ("SFAS") No.
128,  "Earnings per Share,"  basic  earnings per share were computed by dividing
net  earnings  by  the  weighted  average  number  of  shares  of  common  stock
outstanding  during the year. The  reconciliation of basic earnings per share to
diluted earnings per share is shown in the following  table.  Computation of the
loss per share for 1995,  on a diluted  basis,  is omitted  because  options and
warrants have an antidilutive effect.

As a result of the adoption of SFAS No. 128, the Corporation's reported earnings
per share ("EPS") for 1996 were restated as follows:

3. Financing Arrangements

Accounts  Receivable  Facility.  The  Corporation  has  an  accounts  receivable
facility  (the  "Receivables  Facility")  in which USG  Funding  Corporation,  a
special-purpose subsidiary of the Corporation formed under Delaware law, entered
into agreements with United States Gypsum Company and USG Interiors,  Inc. These
agreements  provide  that USG Funding  purchases  trade  receivables  (excluding
intercompany receivables owed by L&W Supply) of U.S. Gypsum and USG Interiors as
generated,  in a transaction  designed to be a "true sale" under applicable law.
USG Funding is a party to a Master Trust  arrangement (the "Master Trust") under
which the purchased  receivables are then transferred to Chase Manhattan Bank as
Trustee to be held for the  benefit of  certificate  holders  in such  trust.  A
residual  interest  in  the  Master  Trust  is  owned  by  USG  Funding  through
subordinated certificates.  Under a supplement to the Master Trust, certificates
representing  an  ownership  interest in the Master  Trust of up to $130 million
have been issued to Citicorp Securities,  Inc. Debt issued under the Receivables
Facility  has a final  maturity  in 2004 but may be  prepaid  at any  time.  The
interest  rate on such debt is fixed at 8.2% through a long-term  interest  rate
swap.  Pursuant to the  applicable  reserve and  eligibility  requirements,  the
maximum  amount of debt issuable under the  Receivables  Facility as of December
31, 1997 and 1996,  (including $80 million outstanding as of each date) was $107
million and $105  million,  respectively.  Under the  foregoing  agreements  and
related  documentation,  USG Funding is a separate corporate entity with its own
separate  creditors  that will be entitled to be satisfied  out of USG Funding's
assets prior to distribution of any value to its shareholder.

As of December 31, 1997 and 1996, the outstanding balance of receivables sold to
USG Funding and held under the Master Trust was $179  million and $157  million,
respectively,  and debt  outstanding  under  the  Receivables  Facility  was $80
million as of each date. Receivables and debt outstanding in connection with the
Receivables Facility remain in receivables and long-term debt, respectively,  on
the Consolidated Balance Sheet.

Shelf  Registration.  In 1996, the Securities and Exchange  Commission  declared
effective a shelf  registration  statement that allows the  Corporation to offer
from time to time (i) debt  securities  (ii) shares of $1.00 par value preferred
stock (iii)  shares of $0.10 par value  common  stock  and/or  (iv)  warrants to
purchase shares of common stock, all having an aggregate  initial offering price
not to exceed  $300  million.  As of the filing date of the  Corporation's  1997
Annual  Report on Form 10-K,  no  securities  had been  issued  pursuant to this
registration.


4. Debt

Total debt, including debt maturing within one year, as of
December 31 consisted of the following:

Total                                         620        755 
=============================================================


The Corporation  maintains a $500 million  unsecured  revolving credit facility,
which includes a $125 million letter of credit subfacility,  with a syndicate of
banks under a credit  agreement.  The revolving  credit facility expires in 2002
with no  required  amortization  prior to  maturity.  As of December  31,  1997,
outstanding  revolving  loans totaled $25 million,  and letters of credit issued
and  outstanding  amounted to $84  million,  leaving the  Corporation  with $391
million of available credit under the revolving  credit facility.  The revolving
loans bear interest at the London Interbank Offered Rate ("LIBOR") as determined
from time to time plus an applicable  spread based on the Corporation's net debt
to EBITDA  ratio (as defined in the credit  agreement)  for the  preceding  four
quarters.  As of December 31, 1997, the applicable  spread was 0.4%. The average
rate of interest on the revolving loans was 6.1% and 6.3% during the years ended
December 31, 1997 and 1996, respectively. See "Note 5. Financial Instruments and
Risk  Management"  for  information  on instruments  used by the  Corporation to
manage the impact of interest rate changes on LIBOR-based  bank debt. The credit
agreement contains restrictions on the operation of the Corporation's  business,
including covenants  pertaining to liens, sale and leaseback  transactions,  and
mergers and acquisitions of businesses not related to the building industry.

On June 2, 1997, the Corporation  executed through CGC Inc. a $77 million (U.S.)
($110 million Canadian), parent-guaranteed,  Canadian credit facility due 2002.
This  facility  was later  amended to  increase  the credit  line by $14 million
(U.S.) ($20 million Canadian) for one year. As of December 31, 1997, outstanding
loans totaled $72 million (U.S.), leaving $19 million (U.S.) of available credit
under  this  facility.  The method of  calculating  interest  and the  covenants
related to this facility are  virtually the same as those for the U.S.  facility
described  above.  The average rate of interest on the  Canadian  loans was 4.6%
during the period of June 2, 1997,  through  December 31, 1997. The average rate
of interest on a different  Canadian  credit  facility that was in effect during
the period of January 1, 1997,  through  its  termination  on June 4, 1997,  was
6.2%.

The Corporation also maintains a  parent-guaranteed,  multicurrency ($20 million
U.S.  equivalent),  European line of credit. As of December 31, 1997, there were
no outstanding loans under this facility.

The industrial  revenue bonds had interest rates ranging from 3.7% to 8.8%, with
maturities  through  2032.  All debt  classified  as "other  debt"  had  average
interest rates of 4.5% and 4.6% as of December 31, 1997 and 1996,  respectively,
with varying payments due through 2006.

There  were no  short-term  borrowings  outstanding  as of  December  31,  1997.
Short-term  borrowings  outstanding as of December 31, 1996, totaled $7 million,
and the weighted  average  interest rate on these borrowings as of that date was
4.2%.

The fair  market  value of total  debt  outstanding  was $646  million  and $788
million as of December 31, 1997 and 1996, respectively, based on indicative bond
prices as of those dates.

As of December 31, 1997,  aggregate scheduled  maturities of long-term debt were
$10  million  for each year 1998  through  2000,  $160  million in 2001 and $107
million in 2002.


5. Financial Instruments and Risk Management


The following  table  presents the carrying  amounts and estimated fair value of
the Corporation's derivative portfolio as of December 31:

The amounts  reported as fair value  represent the market value as obtained from
broker  quotations.  The negative  fair values are  estimates of the amounts the
Corporation  would need to pay as of December  31, 1997 and 1996,  to cancel the
contracts or transfer them to other parties.

The  Corporation is exposed to credit losses in the event of  nonperformance  by
the  counterparties on all its derivative  contracts.  All  counterparties  have
investment grade credit standing;  accordingly, the Corporation anticipates that
these  counterparties  will be able to satisfy fully their obligations under the
contracts.  The  Corporation  does not obtain  collateral  or other  security to
support  financial  instruments  subject to credit risk but  monitors the credit
standing of counterparties.

Interest Rate Risk  Management.  As of December 31, 1997, the  Corporation had a
swap  agreement  in place  to pay  7.2% in  exchange  for  LIBOR on $25  million
notional principal for the years 1998 through 2000. In addition, the Corporation
has  entered  into $80  million of interest  rate swap  agreements  to hedge its
Receivables  Facility on which the  interest  payments  are based on  commercial
paper rates.  Under these agreements,  the Corporation pays a fixed rate of 8.2%
in  exchange  for the  monthly  commercial  paper  rate  due on the  Receivables
Facility.

As of December 31, 1996, the Corporation  owned an interest rate cap that capped
the Corporation's expected LIBOR-based interest payments on $25 million notional
principal at 5.6% for 1997. The Corporation also had swap agreements in place to
pay 7.1% in exchange for LIBOR on $50 million  notional  principal for the years
1997 through 2000 and on $25 million notional principal for 2001 and 2002. Also,
as of December 31, 1996, the  Corporation  had interest rate swap  agreements to
hedge $80 million of its Receivables Facility.

Energy Risk  Management.  As of December 31, 1997 and 1996, the  Corporation had
over-the-counter  swap  agreements  to  exchange  monthly  payments  on notional
amounts of energy  amounting to $30 million and $39 million,  respectively,  all
extending one year or less.

Foreign Exchange Risk Management. As of December 31, 1997, the Corporation had a
number of  foreign  currency  forward  contracts  in place  (primarily  Canadian
dollars and Belgian francs) to hedge its exposure to exchange rate  fluctuations
on foreign currency transactions. These foreign exchange contracts mature on the
anticipated cash requirement date of the hedged transaction,  generally,  within
one year.  As of December  31,  1996,  the  Corporation  had a foreign  exchange
forward  contract  in place to hedge  the  refinancing  of the  purchase  of the
minority  interest in CGC. This contract was for $15 million  (U.S.) and matured
in January  1997.  The  deferred  gain on this  foreign  exchange  hedge was not
significant as of December 31, 1996.


6. Purchase of Subsidiary Minority Interest


In the fourth quarter of 1996, the Corporation  purchased the minority  interest
in its  Canadian  subsidiary,  CGC.  The common  shares of  publicly  held stock
totaled  approximately  6 million and were acquired at a price of $11 (Canadian)
per share. The total amount paid in U.S. dollars for the shares was $49 million.
This payment was financed  initially through an interim Canadian credit facility
due 1997 that was replaced in 1997 by a long-term  Canadian  credit facility due
2002.  As a result of the  transaction,  CGC  recorded  goodwill  of $41 million
(U.S.),  which is included in other assets on the Consolidated Balance Sheet and
is being amortized over 40 years.


7. Writedown of Assets

In the fourth  quarter of 1995,  the  Corporation  recorded a $30 million pretax
($24 million  after-tax)  charge in connection  with the sale of its  insulation
manufacturing  business in the United States,  which was completed in the second
quarter of 1996, and the closure of its insulation plant in Canada.  Included in
this  charge  is a  $15  million  noncash,  no-tax-impact  write-off  of  excess
reorganization  value  associated  with these  businesses.  The remainder of the
charge primarily reflects a writedown of the assets of these businesses to their
net realizable value. The total charge is reflected in other expense, net in the
Consolidated Statement of Earnings.


8. Income Taxes


Earnings before income taxes consisted of the following:

Significant  components of deferred tax (assets)  liabilities  as of December 31
were as follows:

=====================================================


A valuation  allowance of $90 million,  which had been provided for deferred tax
assets  relating  to  pension  and  retiree   medical   benefits  prior  to  the
Corporation's  financial  restructuring  in 1993,  was  eliminated  in the third
quarter  of 1997.  The  elimination  of this  allowance  reflects  a  change  in
management's  judgment  regarding  the  realizability  of these assets in future
years as a result of the  Corporation's  pretax  earnings  levels  and  improved
capital  structure over the past three years.  In accordance  with SOP 90-7, the
benefit  realized from the  elimination of this allowance was used to reduce the
balance of excess reorganization value to zero in the third quarter of 1997.

The Corporation used a net operating loss carryforward of $100 million to offset
U.S. taxable income in 1994 through 1996.  Because of the uncertainty  regarding
the application of the Internal Revenue Code to this carryforward as a result of
the  Corporation's  financial  restructuring in 1993, the carryforward  could be
reduced or eliminated.

The  Corporation  does not  provide  for U.S.  income  taxes on the  portion  of
undistributed   earnings  of  foreign  subsidiaries  that  are  intended  to  be
permanently  reinvested.  The cumulative amount of such  undistributed  earnings
totaled approximately $144 million as of December 31, 1997. These earnings would
become  taxable  in the  United  States  upon the sale or  liquidation  of these
foreign subsidiaries or upon the remittance of dividends.  It is not practicable
to estimate the amount of the deferred tax liability on such earnings.


9. Inventories

     As of December 31, 1997 and 1996,  the LIFO values of domestic  inventories
were $153 million and $141 million,  respectively, and would have been higher by
$4 million and $7 million,  respectively, if they were valued under the FIFO and
average  production cost methods.  The LIFO value of U.S.  domestic  inventories
exceeded that computed for U.S. federal income tax purposes by $30 million as of
December 31, 1997 and 1996. Inventory  classifications as of December 31 were as
follows:

(millions)                              1997        1996

=======================================================



11. Leases

The  Corporation  leases  certain  of  its  offices,  buildings,  machinery  and
equipment,  and autos under  noncancelable  operating leases.  These leases have
various terms and renewal options.  Lease expense  amounted to $51 million,  $46
million and $41 million in the years ended  December  31,  1997,  1996 and 1995,
respectively. Future minimum lease payments required under operating leases with
initial or  remaining  noncancelable  terms in excess of one year as of December
31, 1997,  were $36 million in 1998,  $31 million in 1999,  $26 million in 2000,
$20 million in 2001 and $18 million in 2002. The aggregate obligation subsequent
to 2002 was $19 million.


12. Employee Retirement Plans

Pension Plans. The Corporation and most of its subsidiaries have defined benefit
retirement plans for all eligible employees. Benefits of the plans are generally
based on years of service and employees'  compensation during the final years of
employment.  The  Corporation's   contributions  are  made  in  accordance  with
independent  actuarial reports. The Corporation made fundings of $25 million and
$13 million in 1997 and 1996,  respectively,  to one of its plans.  Pension plan
assets consist  primarily of publicly traded common stocks and debt  securities.
Net pension expense included the following components:


(millions)                           1997       1996       1995

The expected  long-term rate of return on plan assets was 9% for the years ended
December 31, 1997 and 1996. The assumed  weighted  average discount rate used in
determining the accumulated benefit obligation was 7.25% and 7.5% as of December
31, 1997 and 1996,  respectively.  The rate of  increases  in  projected  future
compensation levels was 5% for both years.

Postretirement  Benefits.  The Corporation  maintains plans that provide retiree
health care and life insurance  benefits for all eligible  employees.  Employees
generally  become  eligible for the retiree benefit plans when they meet minimum
retirement  age and service  requirements.  The cost of providing  most of these
benefits is shared with retirees.  The following table summarizes the components
of net periodic postretirement benefit cost:

The  status  of the  Corporation's  accrued  postretirement  benefit  obligation
recognized on the Consolidated Balance Sheet as of December 31 was as follows:

(millions)                                 1997       1996

===========================================================


The  assumed  health-care-cost  trend  rate used in  measuring  the  accumulated
postretirement  benefit  obligation was 8% as of December 31, 1997, and 9% as of
December 31, 1996,  with a rate gradually  declining to 5% by 2000 and remaining
at  that  level  thereafter.  A  one-percentage-point  increase  in the  assumed
health-care-cost  trend  rate for  each  year  would  increase  the  accumulated
postretirement  benefit obligation by $31 million and $33 million as of December
31,  1997  and  1996,   respectively,   and  would  increase  the  net  periodic
postretirement  benefit  cost by $3 million  and $4 million  for the years ended
December  31, 1997 and 1996,  respectively.  The assumed  discount  rate used in
determining the accumulated postretirement benefit obligation was 7.25% and 7.5%
as of December 31, 1997 and 1996, respectively.

13. Stock-Based Compensation

The Corporation has issued stock options from three  successive  plans under its
long-term  equity program.  Under each of the plans,  options were granted at an
exercise  price  equal to the  market  value on the date of grant.  All  options
granted  under the plans have 10-year terms and vesting  schedules  ranging from
two to three years.  The options  expire on the 10th  anniversary of the date of
the grant, except in the case of retirement,  death or disability, in which case
they  expire  on the  earlier  of the  fifth  anniversary  of such  event or the
expiration of the original option term.

The  Corporation  accounts  for  stock-based  compensation  in  accordance  with
Accounting Principles Board Opinion No. 25 and discloses such compensation under
the provisions of SFAS No. 123, "Accounting for Stock-Based Compensation."

The fair value of each option grant was  estimated as of the date of grant using
the  Black-Scholes  option  pricing  model with the following  weighted  average
assumptions  for options  granted in 1997 and 1996;  no options  were granted in
1995: 
                                    1997       1996

Expected volatility                29.6%      33.0%
Dividend yield                        -          -
- ---------------------------------------------------


The  weighted  average  fair value of  options  granted  during the years  ended
December 31, 1997 and 1996, was $15.61 and $14.17, respectively.

If the  Corporation had elected to recognize  compensation  cost for stock-based
compensation  grants  consistent with the method prescribed by SFAS No. 123, net
earnings  and net earnings per common share for 1997 and 1996 would have changed
to the following pro forma amounts:

There  were  48,919 and 31,488  shares of $0.10 par value  common  stock held in
treasury  as of  December  31, 1997 and 1996,  respectively.  These  shares were
acquired  through the forfeiture of restricted stock and the surrender of shares
in settlement of tax withholding obligations.

Warrants.  As of December 31, 1997 and 1996,  outstanding  warrants  amounted to
2,489,898 and 2,591,091,  respectively. The warrants are exercisable, subject to
applicable securities laws, at any time prior to May 6, 1998, at which time they
expire.  Each share of common stock issued upon  exercise of a warrant  prior to
the distribution  date (as defined in the Rights Agreement  described below) and
prior to the  redemption or expiration of the Rights will be  accompanied  by an
attached  Right  issued  under the terms and  subject to the  conditions  of the
Rights Agreement as it may then be in effect.

On May 6,  1993,  a total of  2,602,566  warrants,  each to  purchase a share of
common  stock at an  exercise  price of $16.14 per share,  in addition to common
stock,  were issued to holders of certain  debt that was  converted to equity in
the financial restructuring implemented on that date. Upon issuance, each of the
warrants entitled the holder to purchase one share of common stock at a purchase
price of $16.14 per share, subject to adjustment under certain events.

Stockholder Rights Plan. On May 6, 1993, a rights plan (the "Rights  Agreement")
was adopted  pursuant to which the  Corporation  declared a distribution  of one
right (the  "Rights")  upon each share of common  stock.  The Rights,  which are
intended  to protect the  Corporation  and its  stockholders  in the event of an
unsolicited attempt to acquire the Corporation,  generally become exercisable 10
days  following  the  announcement  of the  acquisition  of 20% or  more  of the
outstanding  common stock by someone  other than the  Corporation  or one of its
employee benefit plans (10% in the case of an acquisition that the Corporation's
Board of Directors  determines to represent a threat of  acquisition  not in the
best  interests of the  Corporation's  stockholders)  or 10 business  days after
commencement of a tender offer for 30% or more of the outstanding  common stock.
When exercisable,  each of the Rights entitles the registered holder to purchase
one-hundredth of a share of a junior  participating  preferred stock,  series C,
$1.00 par value per share,  at a price of $35 per  one-hundredth  of a preferred
share, subject to adjustment.  The Rights also provide for a so-called "flip-in"
feature and an exchange feature.

In the event that the  Corporation is the surviving  corporation  and its common
stock  remains   outstanding  and  unchanged  in  a  merger  or  other  business
combination with such acquiring party or the acquiring party engages in one of a
number of self-dealing transactions specified in the Rights Agreement, or in the
event that there is a 10% acquisition that the Board of Directors  determines to
represent a threat of acquisition not in the best interests of the Corporation's
stockholders,  each  holder of a Right,  other than the  acquiring  party,  will
thereafter  have the right,  subject to the  exchange  feature,  to receive upon
exercise  thereof that number of shares of common stock having a market value at
the time of such transaction of two times the exercise price of the Right.


15. Industry and Geographic Segments

Transactions  between  industry and  geographic  segments are  accounted  for at
transfer  prices  that are  approximately  equal to market  value.  Intercompany
transfers   between   industry  and   geographic   segments  are  not  material.
Eliminations  reflect  intercompany sales between industry  segments.  No single
customer  accounted for 10% or more of consolidated  net sales.  Export sales to
foreign  unaffiliated  customers  represent  less than 10% of  consolidated  net
sales.  Segment operating profit (loss) includes all costs and expenses directly
related to the segment  involved and an allocation of expenses that benefit more
than one segment.  Segment  operating  profit  (loss) also  includes the noncash
amortization of excess  reorganization  value,  which had the impact of reducing
operating profit and identifiable assets for North American Gypsum and Worldwide
Ceilings.

Corporate identifiable assets include the assets of USG Funding, which represent
the  outstanding  balances of  receivables  purchased  from U.S.  Gypsum and USG
Interiors,  net of  reserves.  As of  December  31,  1997,  1996 and 1995,  such
receivables,  net of reserves,  amounted to $128 million,  $121 million and $110
million,  respectively,  including  $95  million,  $89  million  and $78 million
purchased  from  U.S.  Gypsum  and $33  million,  $32  million  and $32  million
purchased from USG Interiors as of the respective dates.

16. Litigation

Asbestos   and  Related   Insurance   Litigation.   One  of  the   Corporation's
subsidiaries,  U.S. Gypsum,  is among many defendants in lawsuits arising out of
the  manufacture  and sale of  asbestos-containing  materials.  U.S. Gypsum sold
certain asbestos-containing  products beginning in the 1930s; in most cases, the
products were discontinued or asbestos was removed from the formula by 1972, and
no  asbestos-containing  products were sold after 1977.  Some of these  lawsuits
seek to  recover  compensatory  and in many  cases  punitive  damages  for costs
associated  with  the  maintenance  or  removal  and  replacement  of  asbestos-
containing  products in buildings (the  "Property  Damage  Cases").  Others seek
compensatory  and in many cases punitive  damages for personal injury  allegedly
resulting from exposure to  asbestos-containing  products (the "Personal  Injury
Cases").

Property  Damage Cases.  U.S. Gypsum is a defendant in 16 Property Damage Cases,
many of which involve  multiple  buildings.  One of the cases is a conditionally
certified class action  comprised of all colleges and universities in the United
States,  which  certification is presently  limited to the resolution of certain
allegedly  "common"  liability issues (Central  Wesleyan College v. W.R. Grace &
Co., et al., U.S.D.C.  S.C.). Another class action, brought on behalf of various
public  entities  in the  state of  Texas,  was  settled  in  August  1997.  The
settlement  amount  will be paid over the next 12 months  and will be  partially
funded  by  insurance.  Sixteen  additional  property  damage  claims  have been
threatened against U.S. Gypsum.

Results to Date: In total,  U.S. Gypsum has settled  approximately  110 Property
Damage  Cases  involving  240  plaintiffs,  in  addition  to four  class  action
settlements.  Twenty-four cases have been tried to verdict, 16 of which were won
by U.S. Gypsum and five lost;  three other cases, one won at the trial level and
two lost, were settled during appeals.  In the cases lost,  compensatory  damage
awards against U.S. Gypsum have totaled $11.5 million. Punitive damages totaling
$5.5  million  were  entered  against  U.S.  Gypsum in four  trials.  Two of the
punitive damage awards,  totaling $1.45 million, were paid, and two were settled
during the appellate process.

In 1997,  one Property  Damage Case was filed against U.S.  Gypsum,  three cases
were dismissed before trial, six were settled, one closed case was reopened, and
16 were pending at year end. U.S.  Gypsum  expended $7.8 million for the defense
and resolution of Property Damage Cases and received insurance payments of $15.5
million in 1997.  During 1996, two Property Damage Cases were filed against U.S.
Gypsum, three cases were dismissed before trial, eight were settled, and 23 were
pending at year end;  U.S.  Gypsum  expended  $33.4  million for the defense and
resolution of Property Damage Cases in 1996 and received  insurance  payments of
$84  million.  In 1995,  three  Property  Damage  Cases were filed  against U.S.
Gypsum,  seven cases were dismissed before trial,  three were settled,  two were
closed  following trial or appeal,  and 32 were pending at year end. U.S. Gypsum
expended $36 million for the defense and resolution of Property Damage Cases and
received insurance  payments of $48.6 million in 1995. A substantial  portion of
the insurance  payments  received during the years 1995 through 1997 constituted
reimbursement  for amounts  expended in connection with Property Damage Cases in
prior years.

U. S. Gypsum's  estimated  cost of resolving  pending  Property  Damage Cases is
discussed below. (See "Estimated Cost.")

Personal Injury Cases.  U.S. Gypsum is also a defendant in approximately  67,000
Personal  Injury Cases  pending at December 31, 1997,  as well as an  additional
approximately  7,000 cases that have been  settled but will be closed over time.
Filings of new Personal  Injury Cases totaled  23,500  claims in 1997,  compared
with  28,000  new  claims in 1996 and  14,000  in 1995.  U.S.  Gypsum's  average
settlement  cost for  Personal  Injury  Cases over the past three years has been
approximately $1,600 per claim, exclusive of defense costs.  Management does not
anticipate that the average  settlement  cost for currently  pending claims will
vary  significantly  from historical  amounts,  due largely to opportunities for
block  settlements of large numbers of claims and the apparently high percentage
of  asbestos  personal  injury  claims  that  appear  to have  been  brought  by
individuals  with  little or no physical  impairment.  However,  other  factors,
including the possible insolvency of co-defendants, could have an adverse impact
on settlement costs.

U.S.  Gypsum  is  a  member,   together  with  19  other  former   producers  of
asbestos-containing   products,   of  the  Center  for  Claims  Resolution  (the
"Center"),  which has assumed the handling of all Personal  Injury Cases pending
against U.S.  Gypsum and the other  members of the Center.  Costs of defense and
settlement are shared among the members of the Center pursuant to  predetermined
sharing  formulae.  Virtually all of U.S. Gypsum's personal injury liability and
defense costs are paid by those of its insurance carriers that in 1985 signed an
Agreement  Concerning  Asbestos-Related  Claims  (the  "Wellington  Agreement"),
obligating them to provide coverage for the defense and indemnity costs incurred
by U.S.  Gypsum in  Personal  Injury  Cases.  Punitive  damages  have never been
awarded  against U.S.  Gypsum in a Personal  Injury Case;  whether such an award
would be covered by insurance  under the  Wellington  Agreement  would depend on
state law and the terms of the individual policies.

U. S. Gypsum and the Center were parties to a class action  settlement  known as
"Georgine"  that would have  required  most future  Personal  Injury Cases to be
resolved  through an  administrative  system and provided  prescribed  levels of
benefits based on the nature of the claimants' physical impairment.  However, on
June 25,  1997,  the  Supreme  Court  affirmed  a May 1996  ruling  by a federal
appellate  court  finding  that class  certification  in Georgine  was  improper
(Amchem Products,  Inc. v. Windsor, Case No. 96-270).  Since the invalidation of
the Georgine  settlement,  U.S.  Gypsum and the other  Center  members have been
named  in  a  substantial  number  of  additional  Personal  Injury  Cases.  The
defendants in Georgine,  including U.S.  Gypsum,  have stated their intention to
pursue another claims-handling vehicle that would serve as an alternative to the
tort system,  although there can be no assurance that such an alternative can be
found and implemented.

During 1997,  approximately 23,500 Personal Injury Cases were filed against U.S.
Gypsum, approximately 5,000 claims were refiled or amended to add U.S. Gypsum as
a defendant,  and  approximately  14,000 were settled or dismissed.  U.S. Gypsum
incurred  expenses  of $31.6  million in 1997 with  respect to  Personal  Injury
Cases,  of  which  $27.2  million  is  being  paid by  insurance.  During  1996,
approximately  28,000 Personal Injury Cases were filed against U.S. Gypsum,  and
approximately 20,000 were settled or dismissed. U.S. Gypsum incurred expenses of
$28.6  million in 1996 with  respect to Personal  Injury  Cases,  of which $21.6
million was paid by insurance. (The reduction in the portion of the cost paid by
insurance  in  1996  was   attributable   to  the  impact  of  certain   insurer
insolvencies.)  During 1995,  approximately  13,000  Personal  Injury Cases were
filed against U.S.  Gypsum,  and 17,600 were settled or dismissed.  U.S.  Gypsum
incurred  expenses  of $32.1  million in 1995 with  respect to  Personal  Injury
Cases,  of which $30.9 million was paid by  insurance.  As of December 31, 1997,
1996 and 1995,  approximately  74,000,  59,600 and 50,000 Personal Injury Cases,
respectively, were pending against U.S. Gypsum.

U. S. Gypsum's  estimated cost of resolving the pending Personal Injury Cases is
discussed below. (See "Estimated Cost.")

Insurance  Coverage Action.  U.S. Gypsum sued its insurance  carriers in 1983 to
obtain  coverage for asbestos cases (the "Coverage  Action") and has settled all
disputes  with 12 of its 17 solvent  carriers.  As of December 31,  1997,  after
deducting insolvent coverage and insurance paid out to date,  approximately $325
million of potential insurance remained, including approximately $140 million of
insurance  from five carriers that have agreed,  subject to certain  limitations
and conditions,  to cover both property  damage and personal injury costs;  $140
million from two carriers that have agreed,  subject to certain  limitations and
conditions,   to  cover  personal  injury  but  not  yet  property  damage;  and
approximately  $45 million from three carriers that have not yet agreed to cover
either.  U.S.  Gypsum is  attempting  to negotiate a resolution  of the Coverage
Action  with  the five  remaining  defendant  carriers  but may be  required  to
litigate additional issues in its effort to secure the contested coverage.

During 1995 and 1996, following an Illinois Appellate Court ruling awarding U.S.
Gypsum  coverage for Property  Damage Cases,  several  carriers paid U.S. Gypsum
approximately  $133 million as  reimbursement  for past  property  damage costs.
These amounts were added to U.S.  Gypsum's reserve for asbestos costs (discussed
below).

Aggregate  insurance  payments exceeded U.S. Gypsum's total expenditures for all
asbestos-related matters,  including property damage, personal injury, insurance
coverage litigation and related expenses,  by $2.3 million for 1997, $41 million
in 1996 and $10 million in 1995, due primarily to nonrecurring reimbursement for
amounts expended in prior years.

Insolvent Carriers:  Four of U.S. Gypsum's domestic insurance carriers,  as well
as  underwriters  of  portions  of various  policies  issued by Lloyds and other
London  market  companies,  providing a total of  approximately  $106 million of
coverage, are insolvent. Because these policies would already have been consumed
by U.S. Gypsum's asbestos expenses to date if the carriers had been solvent, the
insolvencies  will not  adversely  affect  U.S.  Gypsum's  coverage  for  future
asbestos-related   costs.   However,   U.S.   Gypsum  is  pursuing   claims  for
reimbursement  from the  insolvent  estates  and other  sources  and  expects to
recover a  presently  indeterminable  portion of the policy  amounts  from these
sources. In February 1997, U.S. Gypsum was paid approximately $11 million by the
receiver for one of the insolvent carriers.

Estimated Cost. The asbestos  litigation  involves numerous  uncertainties  that
affect U.S. Gypsum's ability to estimate reliably its probable  liability in the
Personal Injury and Property  Damage Cases.  In the Property Damage Cases,  such
uncertainties  include  the  identification  and  volume of  asbestos-containing
products in the buildings at issue in each case,  which is often  disputed;  the
claimed damages associated  therewith;  the viability of statute of limitations,
product identification and other defenses, which varies depending upon the facts
and  jurisdiction of each case; the amount for which such cases can be resolved,
which has normally (but not uniformly) been substantially lower than the claimed
damages;  and the  viability  of claims for punitive and other forms of multiple
damages.  Uncertainties  in  the  Personal  Injury  Cases  include  the  number,
characteristics  and venue of Personal  Injury Cases that are filed against U.S.
Gypsum;  the Center's ability to continue to negotiate  pretrial  settlements at
historical or acceptable levels; the level of physical  impairment of claimants;
the  viability  of claims for  punitive  damages;  and the  Center's  ability to
develop an  alternate  claims-handling  vehicle that retains the key benefits of
Georgine. As a result, any estimate of U.S. Gypsum's liability, while based upon
the best information  currently available,  may not be an accurate prediction of
actual  costs and is subject  to  revision  as  additional  information  becomes
available and developments occur.

Currently Pending Cases: Subject to the above uncertainties and based in part on
information  provided by the Center,  U.S. Gypsum  estimates that it is probable
that currently pending Property Damage and Personal Injury Cases can be resolved
for an amount totaling between $200 million and $265 million,  including defense
costs.  These  amounts are  expected to be expended  over the next three to five
years.  Significant  insurance funding is available for these costs, as detailed
below.

Future Cases: U.S. Gypsum is unable to reasonably estimate the cost of resolving
Property  Damage  Cases  and  Personal  Injury  Cases  that will be filed in the
future. The company  anticipates that few additional  Property Damage Cases will
be filed, as a result of the operation of statutes of limitations and the impact
of certain other factors,  although it is possible that any cases that are filed
may seek substantial  damages. It is anticipated that Personal Injury Cases will
continue to be filed in substantial numbers for the foreseeable future, although
the  percentage  of such cases  filed by  claimants  with  little or no physical
impairment  is expected to remain  high.  However,  the company does not believe
that the number and severity of future cases can be  predicted  with  sufficient
accuracy to provide the basis for a reasonable  estimate of the  liability  that
will be associated with such cases.

Accounting  for Asbestos  Liability:  As of December 31, 1997,  U.S.  Gypsum had
reserved $200 million for liability  from pending  Property  Damage and Personal
Injury Cases  (equaling the lower end of the estimated  range of costs  provided
above).  U.S. Gypsum had a corresponding  receivable from insurance  carriers of
approximately $160 million, the estimated portion of the reserved amount that is
expected to be paid or reimbursed by committed insurance. Additional amounts may
be  reimbursed  by  insurance  depending  upon the  outcome  of  litigation  and
negotiations relating to insurance that is presently disputed.

U.S.  Gypsum had an additional  reserve of $110 million as of December 31, 1997,
that  was  available  for  future  asbestos   liabilities  and  asbestos-related
expenses.  The company  continues  to accrue $18  million per year for  asbestos
costs, and will periodically compare its estimates of liability to then-existing
reserves and available  insurance assets and adjust its reserves as appropriate.
It is possible  that U.S.  Gypsum will  determine in the future that  additional
charges to results of operations  are  necessary,  although  whether  additional
charges  will be  required  and,  if so, the timing and amount of such  charges,
cannot presently be predicted.

Conclusion.  The above estimates and reserves will be re-evaluated  periodically
as additional  information  becomes  available.  It is possible that  additional
charges to earnings  may be  necessary  in the future if the  amounts  reflected
above prove  insufficient  in light of future  events,  and that any such charge
could be material to results of  operations  in the period in which it is taken.
However,  it is  management's  opinion,  taking  into  account  all of the above
information  and  uncertainties,   including  currently  available   information
concerning U.S. Gypsum's liabilities,  reserves and probable insurance coverage,
that the  asbestos  litigation  will not have a material  adverse  effect on the
liquidity or consolidated financial position of the Corporation.

Environmental  Litigation.  The Corporation and certain of its subsidiaries have
been notified by state and federal environmental protection agencies of possible
involvement as one of numerous "potentially  responsible parties" in a number of
so-called  "Superfund"  sites in the United States.  In most of these sites, the
involvement of the  Corporation or its  subsidiaries  is expected to be minimal.
The Corporation believes that appropriate reserves have been established for its
potential  liability in connection with all Superfund sites but is continuing to
review its accruals as additional  information becomes available.  Such reserves
take into  account all known or  estimated  costs  associated  with these sites,
including  site   investigations   and  feasibility   costs,  site  cleanup  and
remediation,  legal  costs,  and  fines  and  penalties,  if any.  In  addition,
environmental  costs connected with site cleanups on USG-owned property are also
covered  by  reserves   established  in  accordance  with  the  foregoing.   The
Corporation believes that neither these matters nor any other known governmental
proceeding regarding  environmental  matters will have a material adverse effect
upon its earnings or consolidated financial position.

                                   ACCOUNTANTS


To the Stockholders and Board of Directors of USG Corporation:
     We  have  audited  the  accompanying  consolidated  balance  sheets  of USG
Corporation  and  subsidiaries as of December 31, 1997 and 1996, and the related
consolidated  statements of earnings and cash flows for the years ended December
31, 1997, 1996 and 1995. These financial  statements are the  responsibility  of
the  Corporation'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
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
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 presentation.
We believe that our audits provide a reasonable basis for our opinion.
     In our opinion,  the financial statements referred to above present fairly,
in  all  material  respects,  the  financial  position  of USG  Corporation  and
subsidiaries  as of  December  31,  1997  and  1996,  and the  results  of their
operations and their cash flows for the years ended December 31, 1997,  1996 and
1995, in conformity with generally accepted accounting principles.

(a)  The noncash amortization of excess  reorganization  value, which had no tax
     impact,  reduced  operating  profit and net earnings by  approximately  $42
     million in each  quarter  during  1996 and in the  first,  second and third
     quarters of 1997.  Excess  reorganization  value,  which was established in
     connection  with a financial  restructuring  in 1993,  was  scheduled to be
     amortized  through April 1998.  However,  in the third quarter of 1997, the
     remaining  balance  of $83  million  was  offset  by the  elimination  of a
     valuation allowance.

(b)  Basic  earnings  per common  share were  calculated  using  average  shares
     outstanding  during the  period.  Diluted  earnings  per common  share were
     calculated  using average shares and common stock  equivalents  outstanding
     during  the  period.  Consequently,  the sum of the  four  quarters  is not
     necessarily additive to the total for the year.

(a)  Due  to  a  financial  restructuring  and  implementation  of  fresh  start
     accounting, financial statements for periods subsequent to May 6, 1993, are
     not  comparable  to  financial  statements  for periods  through that date.
     Accordingly, a vertical line has been added to separate such information.

(b)  Per share  information for the period of January 1 through May 6, 1993, was
     omitted  because,   as  a  result  of  the  financial   restructuring   and
     implementation  of fresh start  accounting,  it is not  meaningful.  Market
     value per common share  reflects the closing  stock price on December 31 of
     the applicable year.

(c)  Total debt is shown at  principal  amounts for all periods  presented.  The
     carrying amounts of total debt (net of unamortized reorganization discount)
     as reflected on the  Corporation's  balance sheets were $755 million,  $907
     million,  $1,122 million,  $1,476 million and $1,461 million as of December
     31, 1996, 1995, 1994 and 1993, and May 6, 1993, respectively.
