The  8 1/2% Senior Notes due 2005 (the "Notes") of USG Corporation ("USG" or the
"Corporation") will mature  on August  1, 2005. Interest  on the  Notes will  be
payable  semi-annually  on February  1  and August  1  of each  year, commencing
February 1, 1996. The Notes  will not be redeemable  prior to maturity and  will
not be entitled to any sinking fund.
    
   
Upon  issuance, the Notes will be senior obligations of the Corporation and will
rank pari passu  with the  Corporation's bank debt  and all  other existing  and
future  senior obligations  of the Corporation.  See "Description  of Notes" and
"Risk Factors -- Holding Company  Structure; Relative Priority of Debt  Claims."
Such  bank debt has been incurred under  a new credit agreement (the "New Credit
Agreement") entered into by the Corporation and certain banks on July 27,  1995.
Borrowings  under  the New  Credit Agreement  and,  pursuant to  negative pledge
clauses, the  Notes  and substantially  all  other public  indebtedness  of  the

the Corporation's domestic subsidiaries granted  pursuant to a collateral  trust
arrangement. Upon repayment of such bank debt and termination of the commitments
of the banks to make advances under the New Credit Agreement, or upon release of
the  collateral  by  the  banks (which  the  banks  are required  to  do  if the
Corporation reaches Investment Grade  Status), the Notes  and such other  senior
indebtedness   will  cease  to  be  secured.   The  Notes  will  be  effectively
subordinated  to  current  and  future  indebtedness  and  liabilities  of   the
Corporation's subsidiaries.
    

The  Corporation has the obligation, subject  to certain conditions, to offer to
repurchase all of the Notes at 100% of the principal amount thereof plus accrued
interest to  the date  of repurchase  (i) upon  the occurrence  of a  Change  of

                                THE CORPORATION

OVERVIEW

    Through  its  subsidiaries,  USG  is  a  leading  manufacturer  of  building
materials, producing a wide range of products for use in new residential and new
nonresidential construction, repair  and remodel,  as well as  products used  in
certain  industrial processes.  The Corporation's  United States  Gypsum Company
subsidiary ("U.S. Gypsum") is  the largest producer of  gypsum wallboard in  the
United States and accounted for approximately one-third of total domestic gypsum
wallboard  sales  in 1994.  USG Interiors  Inc. ("USG  Interiors") is  a leading
supplier of interior ceiling  grid and tile systems,  interior wall systems  and
other  products used primarily in commercial applications. USG Interiors was the
largest producer of ceiling grid and the second largest producer of ceiling tile
in the United  States in 1994,  accounting for over  one-half and  approximately
one-third  of total  domestic sales of  such products,  respectively. L&W Supply
Corporation  ("L&W   Supply"),  the   Corporation's  wholly-owned   distribution
subsidiary,  is the largest distributor of wallboard and related products in the
U.S. and distributed approximately 22% of U.S. Gypsum's 1994 wallboard sales. In
addition to its United States operations, the Corporation's 76% owned subsidiary
CGC Inc.  ("CGC") is  the largest  manufacturer of  gypsum products  in  eastern
Canada and USG International ("USG International") supplies interior systems and
gypsum products in Europe, Asia Pacific and Latin America. For the twelve months
ended  December 31, 1994,  the Corporation had  net sales of  $2,290 million and
generated EBITDA of $325 million. For the three months ended March 31, 1994  and
March  31, 1995, the Corporation had net sales of $506 million and $598 million,
respectively,  and  generated   EBITDA  of   $66  million   and  $106   million,
respectively. See "Recent Developments."

    The  Corporation believes that its leading positions in its core businesses,
low cost  structure, quality  and  breadth of  its  product lines,  emphasis  on
customer  service  and  the  distribution  capabilities  of  L&W  Supply provide
significant competitive advantages. USG's business  strategy is to maintain  and
enhance  its  leading  positions  in  North  America  and  expand  its  presence
internationally. USG is currently implementing  this strategy by: (i)  improving
its  financial position and flexibility  through approximately equal application
of free cash flow to debt reduction and capital expenditures, with an  objective
of  achieving investment grade status; (ii)  enhancing its cost position through
process improvements such  as increasing line  speeds in existing  manufacturing
facilities  and implementing technology  which allows the use  of lower cost raw
materials; and (iii) growing its core  gypsum and ceilings businesses by,  among
other   things,   expanding  its   repair   and  remodel   presence,  increasing
manufacturing capacity  in existing  plants, continuing  to introduce  specialty
product  applications, extending  its penetration of  international markets with
existing products and  further leveraging L&W  Supply's nationwide  distribution
network.

    USG's  operations are organized into two core businesses. The North American
Gypsum business includes U.S.  Gypsum and L&W Supply  in the United States,  the
gypsum business of CGC in Canada and the Corporation's Mexican gypsum operations
("North  American Gypsum"). The  Worldwide Ceilings business  is composed of USG
Interiors, the international interior systems businesses in Europe, Asia Pacific
and Latin America managed as USG International and the interior systems business
of CGC ("Worldwide Ceilings").

NORTH AMERICAN GYPSUM

    U.S. Gypsum is a  vertically integrated manufacturer  of gypsum and  related
products,  including "SHEETROCK" brand wallboard,  joint compound and industrial
gypsum cements  and fillers.  In  1994, U.S.  Gypsum shipped  approximately  7.7
billion  square feet of  wallboard, a record for  the company. The Corporation's
gypsum operations include  41 manufacturing facilities,  14 gypsum quarries  and
mines  and  seven  paper plants  located  throughout North  America,  making the
Corporation virtually self sufficient in its two key raw materials, gypsum  rock
and  paper. Because of its vertical  integration in key raw materials, technical
expertise  and  the  proximity  of  plants  to  major  metropolitan  areas,  the
Corporation  believes that  its wallboard has  the lowest delivered  cost of any
competitor in North America.

    L&W Supply distributed approximately 9% of all gypsum wallboard sold in  the
United  States and distributed 22% of U.S. Gypsum's wallboard sales in 1994. L&W
Supply's 148 distribution  centers located in  34 states offer  a wide range  of
building  products  to  construction contractors,  including  wallboard, drywall
metal, ceiling tile and ceiling  grid. L&W Supply is  able to provide less  than
truckload  quantities of materials directly to job sites and place the materials
in areas  where work  is in  progress  (including the  interior of  homes  under
construction),  thereby  reducing contractors'  material handling  and inventory
requirements.

    For the twelve months ended December 31, 1994, North American Gypsum had net
sales of $1,780 million and generated  EBITDA of $304 million before  allocation
of  corporate expenses. For the three months  ended March 31, 1994 and March 31,
1995, North American  Gypsum had  net sales of  $388 million  and $470  million,
respectively, and generated EBITDA of $61 million and $98 million, respectively,
before allocation of corporate expenses. See "Recent Developments."

WORLDWIDE CEILINGS

   
    USG  Interiors manufactures and markets an  integrated line of products used
primarily for commercial interiors.  Products include ceiling grid,  "ACOUSTONE"
and  "AURATONE" brand  ceiling tile, wall  systems, mineral  wool insulation and
soundproofing  products.  USG   Interiors  accounted  for   over  one-half   and
approximately  one-third of 1994  total sales of ceiling  grid and ceiling tile,
respectively, in the United States, and  CGC is the largest producer of  ceiling
grid  and the second largest marketer of ceiling tile in Canada. The Corporation
believes its leading positions in ceiling grid and tile are attributable to  its
emphasis  on providing total  product solutions through a  broad product line as
well as  its  emphasis  on  marketing  to key  decision  makers  in  the  design
specification   process,  such   as  architects  and   interior  designers.  The
Corporation is  focused  on growing  its  interiors business  through  increased
penetration   of  retail  channels  and   additional  international  sales.  USG
International's net sales in  Europe, Asia Pacific  and Latin America  accounted
for approximately 34% of the Worldwide Ceilings segment's net sales in 1994. For
the  twelve months ended December 31, 1994,  Worldwide Ceilings had net sales of
$594 million and generated EBITDA of $62 million before allocation of  corporate
expenses.  For  the  three months  ended  March  31, 1994  and  March  31, 1995,
Worldwide Ceilings had net sales of $140 million and $149 million, respectively,
and generated  EBITDA  of $15  million  and $18  million,  respectively,  before
allocation of corporate expenses. See "Recent Developments."
    

UNITED STATES INDUSTRY TRENDS

    Demand for the Corporation's products in the United States reflects activity
in  the three  major components  of the  construction industry:  new residential
construction (single and  multi-family homes),  new nonresidential  construction
(offices,  schools,  stores  and  other  institutions)  and  repair  and remodel
activity. In recent years, changes in residential construction activity combined
with growth in  the repair and  remodel component have  partially mitigated  the
impact  of  cyclical  demand  for  overall  new  construction.  New  residential
construction has  shifted toward  more single  family housing,  which  typically
requires  twice as much wallboard as a multi-family home, and the average single
family home size has increased by approximately 15% since 1986. In addition, the
repair and  remodel  component  has  become  an  increasing  percentage  of  the
Corporation's  business, accounting for approximately  35% of 1994 industry-wide
demand for gypsum wallboard and  approximately half of industry-wide demand  for
interior systems products.

                                       4
<PAGE>
Largely as a result of these factors, United States industry shipments of gypsum
wallboard  were 23.7 billion square feet in 1994, as compared to 21.3 billion in
1986, despite an approximate  19% decline in the  number of housing starts  from
1.806 million units in 1986 to 1.457 million units in 1994.

    The  Corporation's  principal executive  offices  are located  at  125 South
Franklin Street, Chicago, Illinois 60606.  Its telephone number at that  address
is 312-606-4000.

                              RECENT DEVELOPMENTS

    On  July 21, 1995, the Corporation reported second quarter 1995 net sales of
$615 million and  EBITDA of  $103 million.  These results  compare favorably  to
second quarter 1994 net sales of $562 million and EBITDA of $87 million.

    For  the first six months  of 1995, net sales  and EBITDA amounted to $1,213
million and $209 million, respectively, up from net sales of $1,068 million  and
EBITDA  of $153 million reported  for the first six  months of 1994. See "Recent
Developments."

                                USE OF PROCEEDS

   
    This offering is part of a refinancing which also includes the  replacement,
on  July 27,  1995, of  the Corporation's previous  bank credit  facility with a
seven year,  $500 million  bank revolving  credit facility  under a  new  credit
agreement  (the "New Credit Agreement"). The Corporation used approximately $190
million  of  borrowings   under  the   New  Credit   Agreement,  together   with
approximately  $2 million of  cash on hand, to  repay all borrowings outstanding
under its previous bank facility. See "Description of New Credit Agreement." The
Corporation intends to  use the  net proceeds  of this  offering, together  with
approximately  $125  million  of  additional  borrowings  under  the  New Credit
Agreement, to redeem all of the  Corporation's outstanding 10 1/4% Senior  Notes
due  2002  (the "10  1/4%  Senior Notes")  and to  pay  call premiums,  fees and
expenses associated  with  the  refinancings.  In  June  1995,  the  Corporation
redeemed  approximately $30 million principal amount of the 10 1/4% Senior Notes
using cash on hand. The Corporation believes that the refinancings will  provide
significant  benefits,  including  lowering  the  Corporation's  funding  costs,
extending approximately  $460 million  of debt  maturities and  simplifying  its
capital   structure  through   the  elimination  of   subsidiary  guarantees  of
Corporation indebtedness. The Notes,  along with the  obligations under the  New
Credit  Agreement ("Bank Debt") and  substantially all other public indebtedness
of the Corporation,  will share in  security interests in  the capital stock  of
certain  subsidiaries, pursuant  to the  Collateral Trust  Agreement and related
pledge and security agreements. Holders of  the Bank Debt primarily control  the
operation of the Collateral Trust. See "Description of Collateral Trust."

                                               assets  of any subsidiary  of the Corporation
                                               upon the latter's liquidation or
                                               reorganization will be  subject to the  prior
                                               claims of such subsidiary's creditors, except
                                               to the extent that the Corporation itself may
                                               be a creditor with enforceable claims against
                                               such subsidiary. Therefore, the Notes will be
                                               effectively   subordinated  to  existing  and
                                               future  liabilities   of  the   Corporation's
                                               subsidiaries.
                                               On  a pro forma basis,  as of March 31, 1995,
                                               assuming  consummation  of  the  transactions
                                               described   under  "Use   of  Proceeds,"  the
                                               Corporation and its  subsidiaries would  have
                                               had  $1,025 million total principal amount of
                                               debt   (before   unamortized   reorganization
                                               discount)   on   a  consolidated   basis  and
                                               subsidiaries of  the Corporation  would  have
                                               been   directly   liable  for   $151  million
                                               principal amount of such debt.
Use of Proceeds..............................  Proceeds from the sale  of the Notes will  be
                                               used,  along  with borrowings  under  the New
                                               Credit  Agreement,  to  redeem  all  of   the
                                               currently  outstanding  10 1/4%  Senior Notes
                                               and to pay applicable call premiums, fees and
                                               expenses. See "Use of Proceeds."
Risk Factors.................................  An  investment  in   the  Notes  involves   a
                                               significant   degree   of  risk.   See  "Risk

                         SUMMARY FINANCIAL INFORMATION
             (Dollars in millions, except gypsum wallboard prices)

    The following table presents summary  historical financial data and  certain
other  information of the  Corporation. Due to the  Restructuring, as defined in
"Management's Discussion and  Analysis of  Results of  Operations and  Financial
Condition,"  and implementation of fresh  start accounting, financial statements
for periods subsequent to May 6, 1993 are not comparable to financial statements
for periods prior to that date. Accordingly,  a vertical line has been added  to
separate  such  information. The  information  in the  table  should be  read in
conjunction with "Selected Consolidated Financial Data" "Management's Discussion
and Analysis  of  Results  of  Operations  and  Financial  Condition,"  and  the
Corporation's  Consolidated Financial Statements and notes thereto, all of which
are included elsewhere in this Prospectus. See "Index to Financial Statements."

     respectively, by $190 million  in the year ended  December 31, 1994 and  by

     amortization,  reorganization  items,  extraordinary items  and  changes in
     accounting principles.  The  Corporation  believes  EBITDA  is  helpful  in
     understanding  cash flow  generated from  operations that  is available for
     taxes,  debt  service  and   capital  expenditures.  In  addition,   EBITDA
     facilitates  the monitoring of covenants related to certain long-term debt.
     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.

(f)  Excludes  Amortization  of  Excess  Reorganization  Value  which  is  shown
     separately under "Earnings Statement Data."

(g)  Gross profit as a percentage of net sales.

(h)  EBITDA as a percentage of net sales.

(i)  Pro  forma cash interest expense for the  three months ended March 31, 1995
     and the  year  ended  December  31,  1994  assumes  that  the  transactions
     described  under "Use of Proceeds" were  consummated as of the beginning of
     each period. The levels of  Bank Debt, the Notes  and 10 1/4% Senior  Notes
     used  in the calculation  of pro forma  cash interest expense  were the pro
     forma  levels  of  such  debt  as   of  March  31,  1995  as  shown   under
     "Capitalization." In addition, pro forma cash interest expense excludes all
     non-cash  amortization of debt reorganization  discount. For these reasons,
     pro forma cash interest  expense is not  comparable to historical  interest
     expense.

(j)  Reflects  the principal amount of pro forma total debt of $1,035 million as
     of December 31, 1994 as  the numerator and EBITDA  of $325 million for  the
     twelve months ended December 31, 1994 as the denominator.

(k)  In billions of square feet.

(l)  Represents  average price per thousand square  feet realized by U.S. Gypsum
     during the periods shown.

                                  RISK FACTORS

    INVESTORS  SHOULD CONSIDER CAREFULLY THE FACTORS SET FORTH BELOW, AS WELL AS
THE OTHER INFORMATION SET FORTH IN THIS PROSPECTUS, PRIOR TO DECIDING WHETHER OR
NOT TO  PURCHASE THE  NOTES. CAPITALIZED  TERMS USED  HEREIN AND  NOT  OTHERWISE
DEFINED HAVE THE MEANINGS ASCRIBED TO THEM ELSEWHERE IN THIS PROSPECTUS.

SUBSTANTIAL LEVERAGE

   
    The  Corporation will remain substantially leveraged upon completion of this
offering. As of  March 31, 1995,  the Corporation had  $1,050 million  principal
amount  of total debt  on a consolidated  basis (which had  a carrying amount of
$1,026 million on the Corporation's  consolidated balance sheet after  deducting
unamortized   reorganization  discount  of   $24  million)  and   a  deficit  in
stockholders' equity of $2 million. As  adjusted to reflect consummation of  the
transactions   described  under  "Use  of  Proceeds,"  the  Corporation's  total
principal amount of debt  on a consolidated basis  and deficit in  stockholders'
equity  as of  March 31,  1995 would  have been  $1,025 million  and $5 million,
respectively. The Corporation  is expected  to have a  deficit in  stockholders'
equity at least through 1998 when reorganization value in excess of identifiable
assets  ("Excess  Reorganization  Value")  will be  fully  amortized.  See "Risk
Factors  --  Recent   Losses,"  "Selected  Consolidated   Financial  Data"   and
"Capitalization."
    

   
    The  degree to which the Corporation is leveraged will pose risks to holders
of the Notes, including, but not limited to, the following: (i) a portion of the
Corporation's cash flow  from operations  will be  dedicated to  the payment  of
principal and interest on its indebtedness, thereby reducing the funds available
to  the Corporation for its operations; (ii) the Corporation's ability to obtain
additional financing in  the future for  working capital, capital  expenditures,
debt  service requirements,  acquisitions, general  corporate or  other purposes
will be restricted; (iii) certain of the Corporation's borrowings carry and will
continue to  carry variable  rates of  interest, which  could result  in  higher
interest  expense in  the event of  an increase  in interest rates  and (iv) the
Corporation may  be  adversely  affected in  the  event  of a  downturn  in  its
business.  These  and  other  factors  could  have  an  adverse  effect  on  the
marketability, price and future value of the Notes.
    

CYCLICAL BUSINESS

    The Corporation's business is cyclical in nature and sensitive to changes in
general economic conditions, including, in particular, conditions in the housing
and construction-based businesses. These businesses are in turn influenced by  a
variety  of factors beyond the  Corporation's control, including interest rates,
consumer confidence, household formation and  general economic conditions. As  a
result  of this cyclicality, the Corporation  has experienced, and in the future
could  experience,  reduced   revenues  and  margins,   which  may  affect   the
Corporation's ability to satisfy its debt service obligations on a timely basis.
The  Corporation  has  experienced a  recovery  in  the businesses  in  which it
competes beginning in  1992, as  evidenced by  increases in  housing starts  and
wallboard  pricing and shipments and improvement  in sales of other construction
products. However, first  quarter 1995 seasonally  adjusted housing starts  were
down  5%  from  the  average  reported  for  the  first  quarter  of  1994.  See
"Management's Discussion and  Analysis of  Results of  Operations and  Financial
Condition  -- First  Quarter Ended  March 31,  1995 Compared  With First Quarter
Ended March  31, 1994"  and  "Recent Developments."  In addition,  recently  the
wallboard  industry has experienced substantial  increases in waste paper prices
which adversely affect operating profit. See "Recent Developments."

ASBESTOS LITIGATION

    One of  the  Corporation's subsidiaries,  U.S.  Gypsum, is  a  defendant  in
asbestos  lawsuits alleging  property damage  (the "Property  Damage Cases") and
personal injury  (the  "Personal Injury  Cases").  Virtually all  costs  of  the
Personal  Injury  Cases  are being  paid  by  insurance. However,  many  of U.S.
Gypsum's insurance carriers are denying coverage for the Property Damage  Cases,
although  U.S. Gypsum  believes that substantial  coverage exists  and the trial
court and  appellate courts  in  U.S. Gypsum's  coverage action  (the  "Coverage
Action") have so ruled.

    In  view of the limited insurance funding currently available to U.S. Gypsum
for Property Damage Cases resulting from continued resistance by a number of its
insurers to providing  coverage, the effect  of the asbestos  litigation on  the
Corporation  will depend upon a variety of factors, including the damages sought
in

                                       10
<PAGE>
Property Damage Cases that reach trial  prior to the resolution of the  Coverage
Action,  U.S. Gypsum's ability to successfully  defend or settle such cases, and
the resolution of  the Coverage  Action. As a  result, management  is unable  to
determine  whether an  adverse outcome  in the  asbestos litigation  will have a
material adverse  effect  on  the  results of  operations  or  the  consolidated
financial  position  of the  Corporation.  The Corporation's  independent public
accountants have also noted this uncertainty in their report with respect to the
financial statements of the Corporation.

RECENT LOSSES

    For the year ended December 31, 1994, the Corporation reported a net loss of
$92 million  after the  amortization of  $169 million  of Excess  Reorganization
Value.  Amortization of Excess Reorganization Value  is a non-cash item which is
not deductible  for federal  income  tax purposes.  See "Index  to  Consolidated
Financial Statements -- Restructured Company -- Notes to Financial Statements --
Financial   Restructuring"   for   additional   information   regarding   Excess
Reorganization Value. For the three months ended March 31, 1995, the Corporation
reported a net  loss of  $2 million  after the  amortization of  $42 million  of
Excess  Reorganization Value.  Amortization of Excess  Reorganization Value will
continue at the rate of  $169 million per year through  1997 and will amount  to
approximately  $64 million in 1998. Although the Corporation's recent net losses
are the result of non-cash items, there can be no assurance that the Corporation
will have net income in the future.

HOLDING COMPANY STRUCTURE; RELATIVE PRIORITY OF DEBT CLAIMS

    The Corporation's  operations are  conducted through  its subsidiaries.  The
Corporation's  ability to service its indebtedness is largely dependent upon the
receipt of funds from its subsidiaries  by way of dividends, interest, loans  or
otherwise. The rights of the Corporation and its creditors, including holders of
the  Notes,  to realize  upon the  assets  of any  subsidiary upon  the latter's
liquidation or  reorganization will  be  subject to  the  prior claims  of  such
subsidiary's  creditors, except to the extent that the Corporation itself may be
a creditor with enforceable claims against such subsidiary. Therefore, the Notes
will be  effectively subordinated  to  existing and  future liabilities  of  the
Corporation's subsidiaries.

   
    As  of  March 31,  1995,  the Corporation  and  its subsidiaries  had $1,050
million total  principal  amount  of  debt  (before  unamortized  reorganization
discount)  on a consolidated  basis. As of  March 31, 1995,  subsidiaries of the
Corporation were directly liable for $151 million principal amount of such debt.
On a  pro forma  basis,  as of  March 31,  1995,  assuming consummation  of  the
transactions  described  under  "Use  of  Proceeds,"  the  Corporation  and  its
subsidiaries would  have  had $1,025  million  total principal  amount  of  debt
(before  unamortized  reorganization  discount)  on  a  consolidated  basis  and
subsidiaries of the Corporation would have been directly liable for $151 million
principal amount  of  such debt.  The  $151 million  of  subsidiary debt  is  in
addition to trade obligations and other liabilities of the subsidiaries to which
the Notes are effectively subordinated.
    

    There  are no  contractual restrictions on  the payment of  dividends by the
Corporation's domestic subsidiaries and  the Indenture contains restrictions  on
the ability of the Corporation to create, permit or suffer to exist any dividend
restrictions  affecting  Restricted  Subsidiaries,  subject  to  certain limited
exceptions. See  "Description of  Notes --  Certain Covenants  -- Limitation  on
Dividend  and  Other  Payment  Restrictions  Affecting  Subsidiaries."  However,
certain of the Corporation's foreign subsidiaries are subject to loan  covenants
or other contractual provisions which could limit their ability to pay dividends
to the Corporation.

NEW CREDIT AGREEMENT AND OTHER RESTRICTIONS

   
    Under  the New  Credit Agreement,  the Corporation  is required  to maintain
minimum interest coverage and debt to  EBITDA ratios. The New Credit  Agreement,
as  well as certain other debt instruments  to which the Corporation is a party,
also  contain  certain  restrictive  covenants   and  events  of  default.   See
"Description   of  New  Credit   Agreement"  and  "Description   of  Other  Debt
Securities."  Among  other  consequences,   such  provisions  could  limit   the
Corporation's  financial and business flexibility  in the future. Furthermore, a
default under  such provisions,  if not  cured  or waived,  could result  in  an
acceleration of some or all of the Corporation's indebtedness.
    

                                       11
<PAGE>
CONTROL OF COLLATERAL TRUST AGREEMENT BY BANK GROUP

   
    The  Notes, together  with the Bank  Debt and approximately  $431 million of
public indebtedness of the Corporation,  will be secured by  a pledge of all  of
the  shares of the Corporation's  major domestic subsidiaries (the "Collateral")
under the Collateral  Trust Agreement  and certain related  pledge and  security
agreements.  Holders of  the Bank  Debt primarily  control the  operation of the
Collateral Trust. The Collateral  Trust will be terminated,  and the Notes  will
become  unsecured, if the  Corporation reaches Investment  Grade Status and will
also be terminated if  the Bank Debt  is repaid or  the collateral is  otherwise
released by the holders of the Bank Debt. In addition, the holders of a majority
of  the  Bank Debt  may  instruct the  Collateral  Trustee to  release specified
portions of the Collateral provided that no Actionable Default has occurred  and
is  continuing. The holders of  the Notes will not  have any rights to authorize
(or prevent) the release of the  Collateral. The Collateral will be released  in
any  event at such time as the Corporation reaches Investment Grade Status or at
such time as the obligations  under the New Credit  Agreement have been paid  in
full,  notwithstanding the fact that there  may be outstanding obligations under
the Notes.
    

   
    The holders of the Bank Debt  also have the exclusive right without  consent
of  the holders of  the Notes to  direct the Collateral  Trustee to exercise, or
refrain from exercising, any rights or  remedies with respect to the  Collateral
following  receipt of a Notice of  Actionable Default. Consequently, the holders
of Notes will have no right to  direct the Collateral Trustee to foreclose  upon
the  Collateral or take  or refrain from  taking any other  actions with respect
thereto even at such times  as the value of  the Collateral may be  diminishing.
See "Description of Collateral Trust."
    

CERTAIN TRADING CONSIDERATIONS

   
    There is currently no trading market for the Notes. Although the Corporation
has caused the Notes to be authorized for listing, subject to official notice of
issuance,  on the New York Stock Exchange under the symbol "USG05," there can be
no assurance that an active  market for the Notes will  develop or, if any  such
market  develops, that it will continue to exist  or as to the liquidity of such
market. In addition, no assurance can be  given that a holder of the Notes  will
be able to sell them in the future or that such sale will be at a price equal to
or  higher than  the initial public  offering price. Furthermore,  the Notes may
trade at a  discount from their  initial public offering  prices depending  upon
prevailing interest rates and other factors.
    

                              RECENT DEVELOPMENTS

    On  July 21,1995, the Corporation reported  second quarter 1995 net sales of
$615 million and  EBITDA of  $103 million.  These results  compare favorably  to
second quarter 1994 net sales of $562 million and EBITDA of $87 million.

    For  the first six months  of 1995, net sales  and EBITDA amounted to $1,213
million and $209 million, respectively, up from net sales of $1,068 million  and
EBITDA of $153 million reported for the first six months of 1994.

    Net losses of $3 million ($0.07 per share) and $17 million ($0.38 per share)
were  reported for the  second quarter of 1995  and 1994, respectively. However,
non-cash amortizations of  excess reorganization value  and reorganization  debt
discount  reduced net earnings by $43 million  ($0.95 per share) and $45 million
($1.00 per share) in the  respective periods. For the  first six months of  1995
and  1994, net losses of $5 million ($0.12 per share) and $51 million ($1.23 per
share) were reported. Comparable amortizations in the six month periods amounted
to  $86  million  ($1.92  per  share)   and  $91  million  ($2.18  per   share),
respectively.

</TABLE>

NORTH AMERICAN GYPSUM

    Second quarter  1995 net  sales of  $483 million  for USG's  North  American
Gypsum  business represented an increase of  $49 million, or 11.3%, while EBITDA
of $95 million improved $15 million, or 18.8%, compared with the second  quarter
of 1994.

    Results  improved for  U.S. Gypsum largely  due to  higher wallboard selling
prices, partially offset by higher  unit manufacturing costs and slightly  lower
wallboard  volume. In addition,  sales of non-wallboard  products, such as joint
compound and DUROCK,  also increased.  U.S. Gypsum's  average wallboard  selling
price was $112.55 per thousand square feet, an increase of 14% compared with the
second  quarter of 1994 and virtually unchanged  from the first quarter of 1995.
Higher manufacturing costs reflect continuing increases in the cost of purchased
waste paper. Compared  to the first  quarter of 1995,  rising waste paper  costs
resulted  in an approximate $3.00 per thousand square feet increase in wallboard
unit manufacturing costs, or  an aggregate increase of  $5.4 million in cost  of
products  sold. Second quarter 1995 shipments  of U.S. Gypsum wallboard totalled
1.801 billion square feet, down 1% from  the comparable 1994 period and down  6%
from the first quarter of 1995.

    Based  on preliminary data issued  by the U.S. Bureau  of the Census, second
quarter 1995 private and public housing starts (not seasonally adjusted) were up
approximately 36% over  the level  reported in the  first quarter  of 1995,  but
approximately  13% below second  quarter 1994 housing starts.  Due to the lagged
effect on demand for wallboard, second quarter 1995 housing starts are  expected
to  favorably impact third quarter shipments  as compared to the second quarter.
However, third quarter 1995 shipments are expected to be down somewhat from  the
all-time  quarterly  record of  2.059 billion  square feet  posted in  the third
quarter of 1994 as a  result of the lower level  of housing starts in 1995.  See
"Risk Factors -- Cyclical Business."

   
    Second  quarter sales  and EBITDA also  improved for  L&W Supply, reflecting
record sales  of  gypsum wallboard  and  non-gypsum products  and  gross  profit
improvements for all of L&W Supply's product lines.
    

WORLDWIDE CEILINGS

    Net sales for USG's Worldwide Ceilings business rose $5 million, or 3.4%, to
$153  million, while EBITDA of $17 million  reflected an increase of $1 million,
or 6.3%, compared with the second quarter of 1994.

                                       13
<PAGE>
Excluding results  for  the domestic  floors  division, which  was  divested  in
December  1994, Worldwide Ceilings net sales  improved $12 million, or 8.5%, and
EBITDA increased $1 million, or 6.3%, versus the second quarter of 1994.

    For USG Interiors, net  sales in the second  quarter of 1995 benefited  from
higher  prices and favorable  demand, while net sales  in the prior-year quarter
were boosted  by an  announced  price increase  effective  in early  July  1994.
Consequently,  net sales were unchanged  quarter-on-quarter (after adjusting for
the divestiture  of the  floors  division). EBITDA  for USG  Interiors  improved
slightly  reflecting the higher 1995 selling  prices. For USG International, net
sales increased due to greater demand. However, EBITDA for USG International was
unchanged from the second quarter of 1994 primarily due to unfavorable  currency
adjustments  which offset improved gross profit  resulting from the higher level
of net sales.

                                USE OF PROCEEDS

   
    This offering is part of a refinancing which also includes the  replacement,
on  July 27,  1995, of  the Corporation's previous  bank credit  facility with a
seven year, $500  million bank revolving  credit facility under  the New  Credit
Agreement.  The Corporation used approximately  $190 million of borrowings under
the New Credit  Agreement, together  with approximately  $2 million  of cash  on
hand,  to repay all borrowings outstanding under its previous bank facility. See
"Description of New Credit  Agreement." The Corporation intends  to use the  net
proceeds   of  this  offering,  together  with  approximately  $125  million  of
additional borrowings  under the  New Credit  Agreement, to  redeem all  of  the
Corporation's  outstanding 10 1/4%  Senior Notes and to  pay call premiums, fees
and expenses associated  with the  refinancings. In June  1995, the  Corporation
redeemed  approximately $30 million principal amount of the 10 1/4% Senior Notes
using cash on hand.  The redemption of  the 10 1/4% Senior  Notes will occur  30
days after the Corporation gives notice thereof. The Corporation expects to give
such  notice  on or  about August  9,  1995. The  Corporation believes  that the
refinancings  will  provide   significant  benefits,   including  lowering   the
Corporation's  funding  costs,  extending  approximately  $460  million  of debt
maturities and  simplifying its  capital structure  through the  elimination  of
subsidiary  guarantees of  Corporation indebtedness.  The Notes,  along with the
Bank Debt and substantially  all other public  indebtedness of the  Corporation,
will  share in security  interests in the capital  stock of certain subsidiaries
pursuant to  the Collateral  Trust  Agreement and  related pledge  and  security
agreements.  Holders of  the Bank  Debt primarily  control the  operation of the
Collateral Trust. See "Description of Collateral Trust."
    

   
    The New Credit  Agreement is  a seven  year, $500  million revolving  credit
facility  which will mature in 2002. The  New Credit Agreement bears interest at
the London Interbank Offered Rate as determined from time to time ("LIBOR") plus
an applicable spread  based on the  Corporation's net debt  to EBITDA ratio  (as
defined)  for the preceding four quarters.  Based on the Corporation's pro forma
financial results  for  the twelve  month  period  ending March  31,  1995,  the
applicable  spread  under  the  New Credit  Agreement  would  have  been 0.875%.
Borrowings under the Corporation's previous credit agreement carried an interest
rate of LIBOR  plus 1.875%.  The New Credit  Agreement is  subject to  permanent
commitment  reductions totalling $100 million if certain financial tests are not
met in the year 2000. See "Description of New Credit Agreement."

                      SELECTED CONSOLIDATED FINANCIAL DATA
             (Dollars in millions, except gypsum wallboard prices)

    The following  table  presents selected  historical  consolidated  financial
information  of the Corporation. Due to  the Restructuring and implementation of
fresh start accounting, financial  statements for periods  subsequent to May  6,
1993  are not comparable to financial statements for periods prior to that date.
Accordingly, a vertical line  has been added to  separate such information.  The
information  provided below has  not been audited.  However, the selected annual
historical consolidated financial information  presented below has been  derived
from  the  Consolidated  Financial  Statements  of  the  Corporation  which were
examined by Arthur Andersen  LLP, whose report with  respect to certain of  such
financial  statements  is  incorporated  by reference  in  this  Prospectus. The
following financial information should be read in conjunction with "Management's
Discussion and Analysis of  Results of Operations  and Financial Condition"  and
the  Corporation's Consolidated Financial Statements  and notes thereto, both of
which are  included  elsewhere  in  this Prospectus.  See  "Index  to  Financial
Statements."

(a)  Fresh  start  accounting  adjustments  were  recorded  on  May  6,  1993 in
     connection with the Restructuring.

(b)  Reflects one-time gain from reorganization items, including an $851 million
     gain from recording Excess Reorganization Value, partially offset by  other
     fresh   start   adjustments,  fees   and   expenses  associated   with  the
     Restructuring and a write-off of  deferred financing costs associated  with
     debt incurred in 1988.

<TABLE>
<S>  <C>
(c)  Amortization  of Excess Reorganization  Value (as defined  herein and shown
     separately above) and  non-cash reorganization debt  discount (included  in
     interest  expense) reduced  reported net  earnings by  $43 million  and $46
     million in the three months ended March 31, 1995 and 1994, respectively, by
     $190 million in the year ended December 31, 1994 and by $121 million in the
     period of May 7 through December 31, 1993.

(d)  Reflects the principal amount of total  debt. The carrying amounts (net  of
     unamortized reorganization debt discount) as reflected on the Corporation's
     balance  sheets were $1,026 million as of March 31, 1995, $1,388 million as
     of March 31, 1994, $1,122 million  as of December 31, 1994, $1,476  million
     as of December 31, 1993 and $1,461 million as of May 6, 1993. Subsequent to
     March   31,  1995,  the  Corporation  redeemed  approximately  $30  million
     principal amount of 10 1/4% Senior Notes using cash on hand.

(e)  EBITDA represents earnings before interest, taxes, depreciation, depletion,
     amortization,  reorganization  items,  extraordinary  items,   discontinued
     operations  and changes in accounting  principles. The Corporation believes
     EBITDA is helpful in understanding cash flow generated from operations that
     is available for taxes, debt service and capital expenditures. In addition,
     EBITDA facilitates the monitoring of covenants related to certain long-term
     debt. 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.

(f)  Excludes  Amortization  of  Excess  Reorganization  Value  which  is  shown
     separately under "Earnings Statement Data."

(g)  Gross profit as a percentage of net sales.

(h)  EBITDA as a percentage of net sales.

(i)  Pro forma cash interest expense for  the three months ended March 31,  1995
     and the year ended December 31 1994 assumes that the transactions described
     under  "Use  of Proceeds"  were  consummated as  of  the beginning  of each
     period. The levels of Bank Debt, the Notes and 10 1/4% Senior Notes used in
     the calculation  of pro  forma cash  interest expense  were the  pro  forma
     levels  of such debt as of March  31, 1995 as shown under "Capitalization."
     In  addition,  pro  forma  cash  interest  expense  excludes  all  non-cash
     amortization  of debt reorganization discount. For these reasons, pro forma
     cash interest expense is not comparable to historical interest expense.

(j)  Reflects the principal amount of pro forma total debt of $1,035 million  as
     of  December 31, 1994 as  the numerator and EBITDA  of $325 million for the
     twelve months ended December 31, 1994 as the denominator.

(k)  For purposes of computing the ratio of earnings from continuing  operations
     to  fixed  charges,  earnings  from continuing  operations  are  defined as
     earnings/(loss) from  continuing operations  before taxes  on income,  plus
     interest  expense, plus, for  the years 1990  through 1993, amortization of
     capitalized financing costs. Fixed charges are defined as interest  expense
     plus  amortization of capitalized  financing costs. The  interest factor in
     rental expense had an insignificant effect on the ratios.

(l)  For the three months ended March 31, 1994, the year ended December 31, 1994
     and the period of May 7 through December 31, 1993, earnings from continuing
     operations were  inadequate to  cover  fixed charges.  The amounts  of  the
     coverage  deficiency  were  $24  million,  $38  million  and  $79  million,
     respectively. Included in earnings from continuing operations before  taxes
     for  these  periods  were  non-cash  charges  for  amortization  of  Excess
     Reorganization Value  of  $42  million,  $169  million  and  $113  million,
     respectively.

(m)  Earnings from continuing operations for the period of January 1 through May
     6,  1993 include a  restructuring gain of $709  million. Without this gain,
     earnings from continuing  operations would  have been  inadequate to  cover
     fixed charges by $52 million.

(n)  For  the  years ended  December  31, 1992,  1991,  and 1990,  earnings from
     continuing operations  were  inadequate  to cover  fixed  charges  by  $224
     million, $194 million, and $60 million, respectively.

(o)  In billions of square feet.

(p)  Represents  average price per thousand square  feet realized by U.S. Gypsum
     during the periods shown.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                          OF RESULTS OF OPERATIONS AND
                              FINANCIAL CONDITION
 FIRST QUARTER ENDED MARCH 31, 1995 COMPARED WITH FIRST QUARTER ENDED MARCH 31,
                                      1994

RESULTS OF OPERATIONS

    Comparing the first three months of  1995 and 1994, net sales increased  $92
million,  or 18.2%. Improved  sales were reported for  both of USG Corporation's
core businesses, North American  Gypsum and Worldwide Ceilings,  as a result  of
strong  housing  starts in  the fourth  quarter  of 1994,  growth in  repair and
remodel activity and improving commercial and institutional construction.

    Gross profit as a percentage  of net sales rose to  25.4% from 21.7% due  to
higher selling prices for all major product lines.

    Selling  and administrative expenses increased $3 million, or 5.3%. However,
as a percentage of net sales, these expenses improved to 10.0% from 11.3%.

    Amortization of  excess  reorganization  value,  which  was  established  in
connection  with  the  Restructuring and  is  being amortized  over  a five-year
period, reduced operating profit  by $42 million in  each first quarter  period.
See "-- Liquidity and Capital Resources."

    Because  of the continuing amortization  of excess reorganization value, USG
reports EBITDA  (earnings before  interest, taxes,  depreciation, depletion  and
amortization)  to  facilitate  comparisons of  current  and  historical results.
EBITDA amounted to $106 million in the  first three months of 1995, an  increase
of  $40 million, or 60.6%, versus the corresponding 1994 period. As a percentage
of net sales, EBITDA increased to 17.7% from 13.0%. (Note: EBITDA should not  be
considered  as  an alternative  to  net earnings  as  an indicator  of operating
performance or to cash flows as a measure of overall liquidity.)

    Interest expense in the first three months of 1995 declined $10 million,  or
27.0%,  compared with the first three months of 1994 primarily reflecting a $389
million net reduction of debt since March 31, 1994.

    Income tax expense  amounted to $27  million and $10  million for the  three
months ended March 31, 1995 and 1994, respectively. The Corporation's income tax
expense   is  computed  based   on  pre-tax  earnings   excluding  the  non-cash
amortization of excess reorganization value, which is not deductible for federal
income tax purposes.  Further, under the  principles of fresh-start  accounting,
the  benefits of the domestic net operating loss carryforwards are not reflected
in income  tax  expense. See  "Index  to Consolidated  Financial  Statements  --
Restructured  Company --  Notes to Financial  Statements -- Taxes  on Income and
Deferred Income Taxes." For 1995, the Corporation anticipates that its effective
tax rate, excluding amortization of excess reorganization value, will be similar
to its 1994 rate of approximately 41%.

    Net losses of $2 million  and $34 million were  reported in the first  three
months  of 1995  and 1994, respectively.  However, the  non-cash amortization of
excess reorganization  value  and  reorganization  debt  discount  (included  in
interest  expense) reduced net earnings by $43  million, or $0.96 per share, and
$46 million, or $1.17 per share, in the respective quarters.

NORTH AMERICAN GYPSUM

    Net sales of $470 million increased $82 million, or 21.1%, and EBITDA of $98
million increased $37 million, or 60.7%, over the first three months of 1994.

    For U.S.  Gypsum, improved  results  were driven  by the  continuing  strong
demand  for gypsum wallboard  and related products.  Despite unfavorable weather
conditions in several  parts of the  United States, wallboard  shipments in  the
first quarter of 1995 totalled 1.925 billion square feet, a first quarter record
and an increase of 3% over the prior-year period. U.S. Gypsum's wallboard plants
operated  at 96% of  capacity in the first  three months of  1995 compared to an
industry average of 93%. Realized selling prices for wallboard averaged  $112.26
per  thousand  square feet,  up  25% and  5% compared  to  the first  and fourth
quarters of 1994,  respectively. However, improved  wallboard margins  resulting
from  the higher selling prices were  partially offset by continued increases in
unit manufacturing  costs as  a result  of the  rising cost  of purchased  waste
paper. Compared to the fourth quarter of 1994, rising waste paper costs resulted
in  an approximate  $2.50 per  thousand square  feet increase  in wallboard unit
manufacturing costs or an aggregate increase of $4.8 million in cost of products
sold. Based on data issued by the U.S. Bureau of the Census, first quarter  1995
seasonally adjusted annual housing starts averaged 1.297 million privately owned
units,  down 5% from the average reported for  the first quarter of 1994. Due to
the lagged effect  on demand for  wallboard, first quarter  1995 housing  starts
will impact second quarter shipments.

    L&W  Supply  Corporation,  USG's  building  products  distribution business,
experienced the highest level  of first quarter net  sales in its history.  This
performance  resulted from  record sales of  gypsum products,  which account for
approximately 50% of L&W  Supply's total sales, and  record sales of  non-gypsum
products.  Improved results for  non-gypsum products were  led by drywall metal,
ceiling products and insulation.

    Results for CGC Inc.'s gypsum business reflect low levels of new residential
construction in eastern Canada, offset by export opportunities and growth in the
repair and remodel  market. Consequently,  CGC's net sales  and EBITDA  improved
slightly  compared to  the first  three months of  1994 due  to higher wallboard
selling prices and increased shipments of wallboard to the United States, offset
to a large extent by decreased shipments in eastern Canada.

WORLDWIDE CEILINGS

    Net sales of $149 million increased $9  million, or 6.4%, and EBITDA of  $18
million increased $3 million, or 20.0%, over the first three months of 1994.

    Slightly  lower net sales  for USG Interiors reflect  the divestiture of the
floor division  in December  1994.  EBITDA for  USG Interiors  increased  15.4%.
Excluding floor division results in 1994, net sales and EBITDA for USG Interiors
increased  7.2%  and  15.4%,  respectively.  These  improvements  reflect higher
average selling  prices for  ceiling  tile and  grid  and record  first  quarter
ceiling tile shipments largely due to strong retail and export sales.

    USG  International reported  increased sales in  all three  of its principal
geographic markets: Europe, Latin America and Asia Pacific. Results for  ceiling
tile in Europe benefited from records in production volume, cost performance and
net sales.

RESULTS OF OPERATIONS

    Due  to the Restructuring, the  Corporation's financial statements effective
May 7, 1993 are not comparable to financial statements for periods prior to that
date. The following information presents 1993 on an annual basis to facilitate a
meaningful  year-to-year  comparison.  See  "Index  to  Consolidated   Financial
Statements -- Restructured Company -- Notes to Financial Statements -- Financial
Restructuring"  for information on the Restructuring and implementation of fresh
start accounting.

    In 1994, improved results in nearly all of the Corporation's businesses  led
to  increased net  sales for  the third  consecutive year,  up $374  million, or
19.5%, over 1993. In 1993, net sales  increased $139 million, or 7.8%, over  the
1992  level. EBITDA  for 1994  increased $107 million,  or 49.1%,  over the 1993
level, which was up $59 million,  or 37.1%, over 1992. Continued improvement  in
gypsum  wallboard  prices  and  record  shipments  of  gypsum  wallboard,  joint
compound, ceiling  tile and  cement  board accounted  for these  results.  These
trends  reflect continued strength in  building materials markets despite rising
interest rates in  1994. Based on  information issued by  the Bureau of  Census,
housing  starts in the United States amounted to 1.457 million units in 1994, up
13% over the 1993 level of 1.288 million units. The 1993 level of housing starts
was 7%  above  the  1992  amount of  1.200  million  units.  New  nonresidential
construction  also improved,  the second  consecutive year  of such  growth, and
demand from repair and remodel expenditures continued to grow.

    In the fourth quarter  of 1994, U.S. Gypsum  recorded a $30 million  pre-tax
charge  to cost of products sold ($17  million after-tax) primarily to cover the
cash portion of two asbestos litigation settlements. Approximately two-thirds of
this amount was paid in  1994 with the remainder payable  in 1995 and 1996.  See
"Index  to Consolidated Financial Statements -- Restructured Company -- Notes to
Financial Statements  --  Litigation"  for  information  on  these  settlements.
Despite  this charge,  gross profit  as a percentage  of net  sales increased to
22.6% in 1994 from 19.4% in 1993  and 17.8% in 1992 reflecting increased  gypsum
wallboard prices.

    Selling and administrative expenses in 1994 increased $24 million, or 10.9%,
over  the prior year  largely due to increased  expenses related to compensation
and benefits and  product and  marketing programs. As  a percent  of net  sales,
however,  these expenses improved to 10.7% in 1994 compared to 11.5% in 1993 and
12.3% in 1992.

    The Corporation began amortizing its excess reorganization value, which  was
established  in connection with the Restructuring, on May 7, 1993. This non-cash
amortization, which will continue through  April 1998, amounted to $169  million
and  $113 million in 1994  and 1993, respectively, with  no counterpart in 1992.
Consequently, operating profit  is not  comparable for  any of  the three  years
shown in the table above.

NORTH AMERICAN GYPSUM

    Net  sales and  EBITDA for  North American  Gypsum continued  to increase in
1994. Net sales increased $337 million, or 23.4%, over the 1993 level, which was
up $147 million, or 11.3%, above 1992. EBITDA increased $117 million, or  62.6%,
in  1994 compared with 1993 after increasing $57 million, or 43.8%, from 1992 to
1993. The U.S. Gypsum component  of EBITDA for 1994  includes the impact of  the
aforementioned   $30   million  charge   associated  with   asbestos  litigation
settlements.

    For U.S.  Gypsum,  continuing improvement  in  gypsum wallboard  prices  and
record shipments of gypsum wallboard, joint compound and DUROCK cement board led
to  improved sales  and profits.  In 1994, net  sales and  EBITDA increased $239
million, or 24.6%, and $100 million, or 67.6%, over the respective 1993 amounts.
Comparing 1993 to 1992,  net sales and EBITDA  increased $99 million, or  11.4%,
and  $47 million, or  46.5%, respectively. Gypsum  wallboard prices continued to
rise from the 14-year low experienced in the

                                       21

first quarter of 1992. For 1994, the average price of wallboard rose 26.6% above
1993, after  increasing 10.5%  in  1993 from  the  1992 average.  U.S.  Gypsum's
average  gypsum wallboard  prices per thousand  square feet by  quarter for 1992
through 1994 were as follows:

    Shipments of gypsum wallboard  in 1994 topped 7.7  billion square feet,  the
highest  level  in  the Corporation's  history,  and  increased by  5%  over the
previous record of  7.3 billion  square feet  in 1993.  U.S. Gypsum's  wallboard
manufacturing  plants operated at 97%  of capacity in 1994  compared with 94% in
1993.

    In 1994, higher  costs for  purchased waste paper  contributed to  increased
unit  manufacturing cost for gypsum  wallboard. U.S. Gypsum's unit manufacturing
cost for wallboard in 1994 increased  due to an increase of approximately  $4.00
per  thousand  square feet,  or a  total increase  of $30.8  million in  cost of
products  sold  due  to   cost  increases  for   purchased  waste  paper.   Unit
manufacturing  cost rose 3% in 1993 from  the 1992 level primarily due to higher
levels of maintenance expenditures and energy cost.

    L&W Supply reported its highest annual sales ever in 1994, up $131  million,
or  24.8%, from 1993. EBITDA for 1994  increased $8 million, or 114.3%, from the
prior year amount. Comparing  1993 to 1992, net  sales and EBITDA increased  $64
million,  or 13.8%, and  $2 million, or  40.0%, respectively. These improvements
reflect higher gypsum wallboard selling prices and increased volume, as well  as
increased sales of other building materials product lines.

    CGC's  gypsum  division experienced  improved  volume for  gypsum wallboard,
particularly in  shipments  to  the  United States,  and  increased  prices  for
wallboard,  primarily due  to increased wallboard  demand in North  America as a
whole. Net sales in 1994 increased $19  million, or 20.9%, over the prior  year,
while  EBITDA increased $6 million, or 66.7%, in the same period. As a result of
the strengthened U.S. dollar  compared with the Canadian  dollar, net sales  for
1993  decreased slightly from the 1992 level. EBITDA, however, tripled from 1992
to $9 million  in 1993  due to higher  selling prices  for wallboard.  Wallboard
prices  in Canada were positively impacted  in 1993 by the Canadian government's
ruling that  dumping  of U.S.-made  wallboard  had occurred  and  the  resulting
imposition  of duties on  gypsum wallboard imported into  Canada from the United
States at  prices below  certain levels.  This ruling  will be  in effect  until
January 1998.

WORLDWIDE CEILINGS

    Net  sales and EBITDA for Worldwide  Ceilings in 1994 increased $54 million,
or 10.0%, and $6 million, or 10.7%, respectively, over 1993. These  improvements
are  in  contrast  to 1992  to  1993 results,  when  net sales  and  EBITDA each
decreased $1 million.

    USG Interiors experienced  record shipments  and higher  prices for  ceiling
tile  in 1994, primarily due  to recovering nonresidential construction markets,
increased sales  to  retail markets  and  increased exports.  Sales  of  ceiling
suspension  grid also  improved in  1994. Compared to  the prior  year, 1994 net
sales and EBITDA  increased $40  million, or 11.1%,  and $5  million, or  10.4%,
respectively.  Net sales and EBITDA for 1993  increased $6 million, or 1.7%, and
$1 million, or 2.1%, respectively,  above 1992. These results reflect  increased
sales to retail markets, which offset a low level of nonresidential construction
in 1993.

    USG International's results reflect improved sales in all regions as well as
continued  cost  improvements in  European operations.  In  1994, net  sales and
EBITDA increased  $17 million,  or 9.2%,  and  $2 million,  or 50.0%,  over  the
respective  1993 amounts. Comparing 1993 to 1992, net sales and EBITDA decreased
$4 million, or 2.1%,  and $1 million, or  20.0%, respectively. The 1993  results
reflect  the combined  impact of  a European  recession and  a strengthened U.S.
dollar compared with European currencies.

OTHER EARNINGS INFORMATION

    Interest  expense continues to decline as  a result of the Restructuring and
subsequent debt repayment and refinancing activities. Interest expense  amounted
to  $149 million in 1994, down $29 million, or 16.3%, from $178 million recorded
in 1993. In 1994,  interest expense includes a  fourth quarter non-cash  pre-tax
charge  of  $16  million  for  the  write-off  of  reorganization  debt discount
primarily in conjunction with the  Corporation's plan to accelerate the  payment
of bank term loans issued under the existing credit agreement and $12 million of
amortization of reorganization debt discount. In 1993, interest expense included
$8  million of amortization  of reorganization debt discount  and $46 million of
interest expense that was  forgiven or converted  to equity as  a result of  the
Restructuring.  Interest expense  decreased $156 million  in 1993  from the 1992
amount of $334 million due to the Restructuring.

    The Corporation's income tax expense  is computed based on pre-tax  earnings
excluding the non-cash amortization of excess reorganization value, which is not
deductible for federal income tax purposes. In 1994, income tax expense amounted
to  $54 million compared  with $46 million in  1993. The Corporation's effective
tax rate for 1994 was negative 142.1%; however, excluding amortization of excess
reorganization value, the Corporation's  1994 effective tax  rate was 41.2%.  An
income  tax  benefit  of  $33  million  was  recorded  in  1992.  See  "Index to
Consolidated Financial Statements -- Notes  to Financial Statements -- Taxes  on
Income  and Deferred  Income Taxes"  for both  the Restructured  and Predecessor
Companies for additional information on income taxes.

    A one-time after-tax net  charge of $150 million  was recorded in the  first
quarter  of 1993 representing the cumulative impact of the adoption of Statement
of Financial Accounting  Standard ("SFAS") No.  106, "Employers' Accounting  for
Postretirement  Benefits Other Than Pensions," and SFAS No. 109, "Accounting for
Income Taxes." See "Financial Statements  and Supplementary Data --  Predecessor
Company  -- Notes to Financial Statements -- Taxes on Income and Deferred Income
Taxes and Postretirement Benefits" for  information related to these  accounting
changes.

    A  net loss of $92 million was recorded in 1994. However, this loss included
the: (i) non-cash amortization of  excess reorganization value of $169  million;
(ii) non-cash amortization of reorganization debt discount of $12 million; (iii)
non-cash  after-tax write-off  of reorganization  debt discount  amounting to $9
million primarily associated with the Bank Term Loans; and (iv) after-tax charge
of $17 million associated with asbestos litigation settlements. Together,  these
items  reduced net earnings  by $207 million,  or $4.81 per  common share. A net
loss of $129 million was  recorded in the period of  May 7 through December  31,
1993  after  amortization  of  excess  reorganization  value  of  $113  million,
amortization of reorganization debt  discount of $8  million, and the  after-tax
extraordinary  loss of $21 million. Net earnings of $1,434 million were recorded
in the period of  January 1 through May  6, 1993, reflecting the  reorganization
items gain of $709 million and the after-tax extraordinary gain of $944 million.
A  net loss of $191 million was recorded in 1992 primarily due to high levels of
interest expense.

LIQUIDITY AND CAPITAL RESOURCES

   
    On May 6, 1993, the  Corporation completed a comprehensive restructuring  of
its debt (the "Restructuring") through implementation of a "prepackaged" plan of
reorganization  under the federal  bankruptcy laws (the  "Prepackaged Plan"). In
accordance with the  terms of  the Prepackaged Plan,  $1.4 billion  of debt  and
accrued  interest was converted into  equity, interest expense was significantly
reduced and  the maturities  of a  substantial portion  of remaining  debt  were
extended.  The Corporation accounted for  the Restructuring using the principles
of fresh start accounting.  See "Index to  Consolidated Financial Statements  --
Predecessor Company -- Notes to Financial Statements -- Financial Restructuring"
for   information  on  the  Restructuring  and  implementation  of  fresh  start
accounting.
    

    Since May 1993, outstanding debt has  been reduced by over $500 million  and
all  but approximately $100 million of scheduled maturities have been eliminated
until 2001. In addition, upon completion of the refinancing described under "Use
of  Proceeds,"  the  Corporation  will   have  approximately  $130  million   of

                                       23
<PAGE>
undrawn  availability  under  the  New  Credit  Agreement.  In  the  absence  of
significant unanticipated  cash  demands,  the Corporation  believes  that  cash
generated  by operations and  the estimated levels of  liquidity available to it
will be sufficient to  satisfy its debt service  requirements and other  capital
requirements.

    The  Corporation  is  currently pursuing  a  strategy of  reducing  debt and
growing its core gypsum and ceilings businesses through the approximately  equal
application  of free cash flow between  debt reduction and capital expenditures,
with an objective of achieving investment grade status. The Corporation  expects
that  capital expenditures will exceed $100 million in 1995. Substantial capital
investments underway  at  North  American Gypsum  plants  include  various  cost
reduction  and capacity expansion projects,  including the installation of stock
cleaning  equipment  to  utilize  lower  grades  of  recycled  paper,  continued
implementation of technology which lowers wallboard weight and additional use of
synthetic gypsum at manufacturing facilities at which it is more economical than
natural  sources of  gypsum rock.  Projects to  enhance manufacturing efficiency
expected to be completed in 1995 are estimated to increase wallboard capacity by
600 million square feet. In the  Worldwide Ceilings business, USG Interiors  has
announced  a  $45 million  expansion of  its ceiling  tile plant  in Greenville,
Mississippi, scheduled for  completion in 1996.  As of March  31, 1995,  capital
expenditure  commitments  for the  replacement,  modernization and  expansion of
operations amounted to $102 million compared with $61 million as of December 31,
1994.  The   Corporation  periodically   evaluates  possible   acquisitions   or
combinations involving other businesses related to its current operations but is
not actively pursuing any potential material acquisitions at the present time.

    As  of  March  31,  1995,  working  capital  (current  assets  less  current
liabilities) amounted to $159 million and the ratio of current assets to current
liabilities was  1.38  to 1,  versus  December  31, 1994  when  working  capital
amounted  to $189 million and the ratio of current assets to current liabilities
was 1.42 to  1. Receivables (net  of reserves) increased  $22 million, or  8.0%,
versus December 31, 1994, to $296 million, inventories increased $17 million, or
9.8%  to $190 million  and accounts payable  increased $23 million,  or 18.9% to
$145 million. These increases primarily reflect normal seasonal fluctuations.

    In the fourth  quarter of  1994, the  Corporation entered  into an  accounts
receivable   facility  (the   "Receivables  Facility")  in   which  USG  Funding
Corporation ("USG Funding"),  a special purpose  subsidiary of the  Corporation,
purchases  trade  receivables (excluding  intercompany  receivables owed  by L&W
Supply) of U.S. Gypsum and USG Interiors as generated. The purchased receivables
are held in a master trust (the  "Master Trust") for the benefit of  certificate
holders  in such  trust. Under  a supplement  to the  Master Trust, certificates
representing an ownership  interest in the  Master Trust of  up to $130  million
were  issued to Citicorp Securities,  Inc. The interest rate  on the debt issued
under the  Receivables  Facility  is  fixed  at  approximately  8.9%  (including
facility  costs) through a  long-term interest rate swap.  Debt issued under the
facility may be  prepaid at  any time. Pursuant  to the  applicable reserve  and
eligibility  requirements,  the  maximum  amount  of  debt  issuable  under  the
Receivables Facility as of December 31, 1994 (including $80 million  outstanding
at  such  date) was  $103  million. Under  the  relevant agreements  and related
documentation, USG Funding is a separate corporate entity with its own  separate
creditors  which will be  entitled to be  satisfied out of  USG Funding's assets
prior to distribution of any value to its shareholder. As of March 31, 1995, the
outstanding balance of receivables sold to USG Funding and held under the Master
Trust was $145 million and debt  outstanding under the Receivables Facility  was
$80 million. Receivables and debt outstanding in connection with the Receivables
Facility  remain  in  receivables  and  long-term  debt,  respectively,  on  the
Corporation's  consolidated  balance  sheet.   See  "Financial  Statements   and
Supplementary  Data -- Restructured Company --  Notes to Financial Statements --
Accounts Receivable Facility  and Indebtedness"  notes for  more information  on
1994 refinancing activities.

    In  the first three months  of 1995, cash and  cash equivalents decreased to
$94 million from $197 million  primarily due to a net  reduction in debt of  $99
million.  First quarter debt repayments included $91 million of bank term loans,
$41 million  of which  satisfied the  remaining 1994  cash sweep  obligation  in
accordance  with the  bank credit  agreement as then  in effect.  The New Credit
Agreement will not contain a cash sweep mechanism. Subsequent to March 31, 1995,
the Corporation called  $30 million face  amount of 10  1/4% Senior Notes  using
cash on hand.

INTRODUCTION

OVERVIEW

    Through  its  subsidiaries,  USG  is  a  leading  manufacturer  of  building
materials, producing a wide range of products for use in new residential and new
nonresidential construction, repair  and remodel,  as well as  products used  in
certain  industrial processes.  U.S. Gypsum  is the  largest producer  of gypsum
wallboard in  the United  States and  accounted for  approximately one-third  of
total  domestic  gypsum wallboard  sales  in 1994.  USG  Interiors is  a leading
supplier of interior ceiling  tile and grid systems,  interior wall systems  and
other  products used primarily in commercial applications. USG Interiors was the
largest producer of ceiling grid and the second largest producer of ceiling tile
in the United  States in 1994,  accounting for over  one-half and  approximately
one-third  of total domestic sales of such products, respectively. L&W Supply is
the largest distributor  of wallboard and  related products in  the U.S. and  in
1994 distributed approximately 22% of U.S. Gypsum's wallboard sales. In addition
to  its United States operations, the  Corporation's 76% owned subsidiary CGC is
the  largest  manufacturer  of  gypsum  products  in  eastern  Canada  and   USG
International supplies interior systems and gypsum wallboard products in Europe,
Asia  Pacific and Latin America. For the  twelve months ended December 31, 1994,
the Corporation had  net sales of  $2,290 million and  generated EBITDA of  $325
million.  For the  three months  ended March  31, 1994  and March  31, 1995, the
Corporation had net sales  of $506 million and  $598 million, respectively,  and
generated  EBITDA of  $66 million  and $106  million, respectively.  See "Recent
Developments."

BUSINESS STRATEGY

    The Corporation believes that its leading positions in its core  businesses,
low  cost  structure, quality  and  breadth of  its  product lines,  emphasis on
customer service  and  the  distribution  capabilities  of  L&W  Supply  provide
significant  competitive advantages. USG's business  strategy is to maintain and
enhance  its  leading  positions  in  North  America  and  expand  its  presence
internationally.  USG is currently implementing  this strategy by: (i) improving
its financial position and  flexibility through approximately equal  application
of  free cash flow to debt reduction and capital expenditures, with an objective
of achieving investment grade status;  (ii) enhancing its cost position  through
process  improvements such as  increasing line speeds  in existing manufacturing
facilities and  implementing  technology  that  allows the  use  of  lower  cost
materials;  and (iii) growing  its core gypsum and  ceiling businesses by, among
other  things,  expanding  its  presence  in  the  repair  and  remodel  market,
increasing  manufacturing capacity  in existing plants,  continuing to introduce
specialty product  applications,  extending  its  penetration  of  international
markets  with existing products  and further leveraging  L&W Supply's nationwide
distribution network.

    REDUCING DEBT  AND  IMPROVING  FINANCIAL  FLEXIBILITY.    The  Corporation's
present  intention is to apply its projected annual free cash flow approximately
equally between debt  reduction and  capital expenditures with  an objective  of
reaching  investment  grade status.  In  addition, the  Corporation  has pursued
opportunities to reduce  near term principal  amortization requirements,  either
through debt reduction or refinancings.

    ENHANCING  ITS COST POSITION.  In 1994, the Corporation began an incremental
process improvement  and capacity  expansion  program at  strategically  located
wallboard plants throughout the United States. This program is expected to lower
its  unit manufacturing  costs while at  the same time  increasing the wallboard

                                       25
<PAGE>
manufacturing capacity of  U.S. Gypsum's  existing plants  by approximately  600
million  square feet  in 1995. Among  the cost reduction  and capacity expansion
programs being implemented by North American Gypsum are the installment of stock
cleaning  equipment  to  utilize  lower  grades  of  recycled  paper,  continued
implementation  of technology which  lowers wallboard weight,  additional use of
synthetic gypsum  at facilities  at which  it is  more economical  than  natural
sources of gypsum and projects to enhance manufacturing efficiency.

    GROWING  THE CORE GYPSUM AND CEILINGS  BUSINESSES.  The Corporation believes
there are substantial opportunities to expand both its North American Gypsum and
Worldwide Ceilings businesses. In North  American Gypsum, the Corporation  seeks
to expand its presence in the growing repair and remodel business through, among
other   things,  additional  penetration  of  retail  channels  and  emphasizing
marketing strategies and product line extensions targeted to the retail customer
(including small contractors  and do-it-yourselfers). North  American Gypsum  is
also  leveraging L&W Supply's  nationwide distribution network  by expanding the
number of third party  product offerings. Worldwide  Ceilings seeks to  increase
its  product leadership  in specialty ceilings  through the  introduction of new
products such as COMPASSO brand ceiling  grid, which allows designers to  create
suspended  ceilings  with  curved edges,  as  well  as increasing  sales  of its
existing products overseas, especially in the  Asia Pacific region, in order  to
capitalize on the evolution of international design specifications toward United
States/European  standards. The Corporation also plans to lower costs and expand
capacity in its  Worldwide Ceilings business,  and has announced  a $45  million
expansion  of its  Greenville, Mississippi ceiling  tile manufacturing facility.
This expansion is in  response to increasing domestic  and worldwide demand  for
its AURATONE brand ceiling tile product. The Corporation believes the Greenville
facility  is among the lowest  cost ceiling tile plants  in the world, and after
completion of the expansion in 1996, will  be the largest ceiling tile plant  in
the world.

UNITED STATES INDUSTRY OVERVIEW

    USG's  consolidated financial performance  is influenced by  activity in the
three major components of  the construction industry in  the United States:  new
residential  construction,  new  nonresidential  construction,  and  repair  and
remodel. In recent years, changes in residential construction activity  combined
with  growth in  the repair and  remodel component have  partially mitigated the
impact of the cyclical demand of the overall new construction components.

NEW RESIDENTIAL CONSTRUCTION

    Demand for  the  Corporation's  products has  historically  been  influenced
primarily   by  new  residential   (single  and  multi-family   homes)  and  new
nonresidential (offices, schools, stores, and other institutions)  construction.
New  residential construction  remains the largest  single source  of demand for
gypsum wallboard in the United States, although it has declined significantly as
a percentage of gypsum wallboard demand since 1986 (a year in which total gypsum
wallboard shipments were  comparable to 1994  levels). Residential  construction
has  a nominal  impact on  demand for  interior systems  products. The following
table sets forth  demand for gypsum  wallboard in the  United States by  end-use
segment  as estimated by U.S. Gypsum  based on publicly available data, internal
surveys  and  data  from  the  Gypsum  Association,  an  industry  trade  group.
Management  estimates that  the distribution  of U.S.  Gypsum's sales  volume to
these four end-use segments is generally proportional to industry demand.

</TABLE>

    Over recent economic cycles, demand for gypsum wallboard has been  favorably
impacted by a shift toward more single family housing within the new residential
construction segment and an increase in the average single family home size. New
single  family  homes,  which  typically  require  twice  as  much  wallboard as
multi-family homes,  accounted for  82%  of total  housing  starts in  1994,  as
compared  to 65% in  1986. Additionally, the  size of the  average single family
home in the United  States increased approximately 15%  to 2,100 square feet  in
1994  from 1,825  square feet  in 1986.  Largely as  a result  of these factors,
United States

                                       26
<PAGE>
industry shipments of gypsum wallboard were 23.7 billion square feet in 1994, as
compared to 21.3  billion in  1986, despite an  approximate 19%  decline in  the
number of housing starts from 1.806 million units in 1986 to 1.457 million units
in 1994, as depicted in the following chart.

</TABLE>

NEW NONRESIDENTIAL CONSTRUCTION

    In   recent  years,   demand  for   interior  systems   resulting  from  new
nonresidential construction, and particularly demand resulting from construction
of new office  space, has  declined as a  percentage of  total interior  systems
demand.  The Corporation believes that new nonresidential construction currently
accounts for approximately  one-half of industry  interior systems demand,  down
from approximately two-thirds in 1986, and that construction of new office space
currently  accounts  for less  than 15%  of total  interior systems  demand. The
balance of  interior  systems  demand  is represented  by  repair  and  remodel,
including  retail. Declining office vacancy rates have caused demand to shift to
the repair and remodel  component in recent years,  as existing office space  is
finished  prior to initial occupancy or as landlords refurbish older space as an
inducement to attract or retain  tenants. In addition, non-office demand  (which
includes  stores, entertainment  facilities, restaurant  facilities and schools)
for interior  systems has  also  increased as  a  percentage of  total  interior
systems demand.

    Nonresidential  construction demand  has accounted for  approximately 10% of
gypsum wallboard industry demand in the United States.

REPAIR AND REMODEL

    Management estimates that repair and remodel demand for gypsum wallboard has
increased more than  22% since 1986  and, in  1994, accounted for  35% of  total
industry  demand  for gypsum  wallboard  in the  United  States. The  repair and
remodel business is relatively  stable and management  believes that the  growth
rate  is approximately 3%  to 5% per year.  The growth of  repair and remodel is
primarily due to the  aging of housing stock,  remodeling of existing  buildings
and  tenant turnover in commercial space. The median age of housing stock was 27
years  in  1990,  and  the   National  Association  of  Homebuilders   forecasts

                                       27
<PAGE>
that  the median age will increase to 32 years by 2000. Management believes that
the continued aging of  housing stock will contribute  to further growth in  the
repair  and remodel business. Demand in the repair and remodel business tends to
be more stable than in new construction, although it does fluctuate somewhat  in
response to general economic conditions.

    Management  believes that the increase in the number of commercial buildings
over the  last decade  provides a  greater base  for nonresidential  repair  and
remodel  activity in the  future, as building owners  or tenants replace ceiling
and wall systems as  part of the tenant  turnover process. Management  estimates
that   approximately  one-half  of  USG  Interiors'   1994  sales  were  to  the
nonresidential repair and remodel segment.

NORTH AMERICAN GYPSUM

BUSINESS

    North American Gypsum  includes U.S.  Gypsum and  L&W Supply  in the  United
States,  the gypsum business of the  Corporation's 76%-owned subsidiary, CGC, in
Canada and Yeso Panamericano S.A. de C.V. ("YPSA"), USG's operations in Mexico.

    CGC is  the largest  manufacturer  of gypsum  wallboard in  eastern  Canada.
Management  estimates  that  industry  sales in  eastern  Canada,  including the
Toronto and Montreal metropolitan  areas, represent approximately two-thirds  of
total  Canadian sales  volume. In 1994,  CGC accounted for  approximately 45% of
industry sales in eastern Canada.

PRODUCTS

    North American  Gypsum  manufactures  and markets  building  and  industrial
products  used in a variety  of applications. Gypsum panel  products are used to
finish the interior  walls and  ceilings in residential,  commercial and  mobile
home  construction. These products provide aesthetic  as well as sound dampening
and fire retarding  value. The  majority of these  products are  sold under  the
"SHEETROCK"  brand name. Also sold under the "SHEETROCK" brand name is a line of
joint compounds used for finishing wallboard joints. The "DUROCK" line of cement
board  and  accessories  provides  fire-resistant  and  water  damage  resistant
assemblies  for both  interior and  exterior construction.  The Corporation also
produces a  variety of  plaster products  used to  provide a  custom finish  for
residential  and commercial interiors, as well  as gypsum-based products sold to
agricultural and  industrial customers  for  use in  a number  of  applications,
including soil conditioning, road repair, fireproofing and ceramics.

MANUFACTURING

    Gypsum and related  products are produced  by the Corporation  at 41  plants
located  throughout the United States, eastern Canada and in central Mexico. The
geographic distribution  of the  Corporation's gypsum  plants enhance  its  cost
position  by  minimizing transportation  costs  to major  metropolitan  areas, a
significant  component  of  total  delivered   wallboard  cost.  In  1994,   the
Corporation  began  an incremental  process  improvement and  wallboard capacity
expansion at strategically  located plants  throughout the  United States.  This
program is expected to lower U.S. Gypsum's unit manufacturing costs while at the
same  time increasing its wallboard capacity by approximately 600 million square
feet.

    Gypsum rock is mined or quarried at 14 company-owned locations in the United
States and Canada. In 1994, these  facilities provided approximately 95% of  the
gypsum  used by  the Corporation's  plants in  North America,  with most  of the
remainder being  synthetic gypsum.  The Corporation's  geologists estimate  that
recoverable  rock reserves  are sufficient for  more than 30  years of operation
based on the Corporation's average annual production of crude gypsum during  the
past  five years.  Proven reserves  contain approximately  232 million  tons, of
which approximately 70%  are located  in the United  States and  30% in  Canada.
Additional  reserves of approximately 153 million tons exist on three properties
not in operation.  The Corporation's  total average annual  production of  crude
gypsum  in  the United  States and  Canada during  the past  five years  was 9.7
million tons. Synthetic gypsum, which the Corporation purchases under  long-term
contracts  from coal-fired power generation plants,  is a by-product of the coal
desulferization process.

    USG owns and operates  seven paper mills located  across the United  States.
Vertical  integration in  this key raw  material ensures a  continuous supply of
high quality paper  that is tailored  to the specific  needs of USG's  wallboard
production process.

    USG  maintains  the  gypsum  industry's  largest  research  and  development
facility, located  in  Libertyville,  Illinois.  This  facility  conducts  fire,
structural  and acoustical testing and product and process development. Research
and development  activities involve  technology  related to  gypsum,  cellulosic
fiber  and  cement as  the primary  raw  materials on  which panel  products and
systems, such as gypsum board, cement board and ceiling tile, are based. Related
technologies are those pertaining to joint compounds and textures for  wallboard
finishing,  specialty  plaster  products for  both  construction  and industrial
applications, coatings  and  latex  polymers. Product  and  process  development
research  from  the  Libertyville  facility  plays  a  significant  role  in the
Corporation's ongoing cost reduction efforts, as many potential improvements are
tested at Libertyville before implementation in manufacturing plants.

MARKETING AND DISTRIBUTION

    Distribution is carried out through L&W Supply's 148 distribution centers in
34 states, as  well as  through home  improvement centers  and other  retailers,
building  material dealers, contractors and distributors. L&W Supply specializes
in delivering less than truckload quantities of construction materials to a  job
site  and places them in areas where  work is being done (including the interior
of a  home  under construction),  thereby  reducing  the need  for  handling  by
contractors. Although L&W Supply specializes in distribution of gypsum wallboard
(which  accounts for approximately  50% of its total  net sales), joint compound
and other products manufactured  primarily by U.S.  Gypsum, it also  distributes
products  manufactured  by USG  Interiors such  as  acoustical ceiling  tile and
ceiling grid  and  products of  other  manufacturers, including  drywall  metal,
insulation, roofing products and accessories.

COMPETITION

    The  Corporation competes in North America as the largest of 18 producers of
gypsum wallboard products and, in 1994, accounted for approximately one-third of
total  gypsum  wallboard  sales   in  the  United   States.  No  new   wallboard
manufacturing  plants have  been opened since  1990, and the  Corporation is not
aware of plans  to build any  new plants. Total  domestic industry shipments  of
gypsum  wallboard totalled 23.7  billion square feet  in 1994, a  record for the
industry, and US Gypsum's shipments of gypsum wallboard

                                       29
<PAGE>
totaled 7.7  billion  square feet,  also  a  record level.  The  second  largest
competitor  in the gypsum  wallboard industry, National  Gypsum Company, shipped
approximately  5.5  billion  square  feet  of  wallboard  in  1994  and  has  18
manufacturing  plants. Principal manufacturers of wallboard in the United States
are set forth below:

MANUFACTURING

    Worldwide  Ceilings products are manufactured at  21 plants located in North
America, Europe, New Zealand and Malaysia, including 5 ceiling tile plants and 9
ceiling grid plants. The  remaining plants produce  other interior products  and
raw  materials for ceiling  tile and grid.  Principal raw materials  used in the
production of Worldwide Ceilings products include mineral fiber, steel, aluminum
extrusions and  high-pressure  laminates. Certain  of  these raw  materials  are
produced  internally, while others are  obtained from various outside suppliers.
Shortages of raw materials used in this segment are not expected.

MARKETING AND DISTRIBUTION

    Worldwide Ceilings products are sold primarily in markets related to the new
construction and renovation of commercial buildings as well as the retail market
for small commercial contractors. Marketing and distribution to large commercial
users  is  conducted  through  a   network  of  distributors  and   installation
contractors  as well as through L&W  Supply. In recent years, Worldwide Ceilings
has increased its emphasis on retail customers, including both small contractors
and do-it-yourselfers, as well as increasing sales of existing products  abroad.
In  the domestic retail segment, Worldwide  Ceilings has increased sales through
marketing strategies  tailored to  home  improvement retailers  which  emphasize
increased  inventory turn through the stocking  of a selected product assortment
of USG Interiors' most popular  offerings. In the international area,  Worldwide
Ceilings  is attempting to  capitalize on the  evolution of international design
specifications  toward  United   States/European  standards  through   selective
expansion  of  its international  sales  force, exploration  of  joint marketing
agreements with foreign-based companies where appropriate and increasing product
availability from its manufacturing base within each region.

    USG Interiors maintains its own  research and development facility in  Avon,
Ohio,  which  provides  product  design,  engineering  and  testing  services in
addition to manufacturing development, primarily in metal forming, with tool and
machine design and construction services. Additional research and development is
carried  out  at   the  Corporation's   research  and   development  center   in
Libertyville,  Illinois and at  its "Solutions Center"SM  located near Chicago's
Merchandise Mart.

COMPETITION

    The Corporation estimates  that it  is the world's  largest manufacturer  of
ceiling grid. USG's most significant competitor is Chicago Metallic Corporation,
which participates worldwide. Other competitors in ceiling grid include W.A.V.E.
(a joint venture of Armstrong World Industries, Inc. and Worthington Industries/
National Rolling Mills).

    The  Corporation estimates that  it accounts for  approximately one-third of
sales  of  acoustical  ceiling  tile  to  the  U.S.  market.  Principal   global
competitors include Armstrong World Industries, Inc. (the largest manufacturer),
OWA Faserplattenwerk GmbH (Odenwald) and The Celotex Corporation.

GENERAL INFORMATION

ASBESTOS LITIGATION DEVELOPMENTS

    A discussion of the Corporation's pending asbestos litigation as of December
31,  1994 is contained in  "Index to Financial Statements  -- Notes to Financial
Statements -- Litigation". Subsequent to the date of those financial statements,
there have been  several important  developments with respect  to U.S.  Gypsum's
declaratory  judgment action against its insurance  carriers. First, on April 5,
1995, the Illinois  Supreme Court  denied the  insurers' petition  for leave  to
appeal the November 4, 1994 ruling of the Illinois Appellate Court. In May 1995,
the  Illinois Supreme Court denied  the insurers' motion seeking reconsideration
of the denial of  leave to appeal.  In addition, during April  1995, one of  the
defendant  carriers, which  provided both  primary and  excess policies  to U.S.
Gypsum during the 1960's and 1970's, agreed to pay U.S. Gypsum a total of  $38.4
million representing the aggregate face amount of the policy, plus certain legal
expenses and other costs. $25 million was paid in April 1995 with the rest to be
paid in three annual installments.

                      DESCRIPTION OF NEW CREDIT AGREEMENT

OVERVIEW

   
    The Corporation has arranged a new seven year $500 million secured revolving
credit  facility  (the "New  Credit Facility")  with a  syndicate of  banks (the
"Banks" or the "Bank Group"). Chemical Bank ("Chemical") is serving as sole  and
exclusive  agent. The Corporation entered into  the New Credit Agreement on July
27, 1995.
    

   
    A copy  of  the  New  Credit  Agreement  is  filed  as  an  exhibit  to  the
Registration  Statement of  which this  Prospectus forms  a part.  The following
summary of the  New Credit  Agreement does  not purport  to be  complete and  is
qualified in its entirety by reference to the New Credit Agreement.
    

THE NEW CREDIT FACILITY

   
    The  New Credit  Facility is  a seven-year  revolving credit  facility in an
aggregate  maximum  amount  of  $500  million,  including  a  letter  of  credit
subfacility  of  up  to $125  million  .  The New  Credit  Facility  consists of
revolving loans ("Revolving  Loans"), including an  uncommitted bid option,  and
letters  of credit ("L/C's"). Except as described below, the New Credit Facility
expires in 2002 and will not require amortization prior to maturity.
    

    If the "Debt/EBITDA  Ratio" (as defined  below) exceeds 2.5  to 1.0 for  the
fiscal  quarter ended June 30, 2000, the New Credit Facility will be permanently
reduced by $100 million, $50 million of such reduction to be effective as of the
date the quarterly financial statements for such fiscal quarter are delivered to
the agent (or, if  not delivered, effective  as of the  fifth day following  the
date such financial statements were due) and $50 million of such reduction to be
effective  12 months thereafter. Any outstanding  amounts which would exceed the
reduced  commitment  must  be  repaid  together  with  any  breakage  costs,  if
applicable.

INTEREST RATE

   
    Interest on the Revolving Loans is computed based on (i) Alternate Base Rate
or  (ii) LIBOR plus the applicable spread (the "LIBOR Spread"). Until either the
Debt/EBITDA Ratio certificate or such  certificate and financial statements  for
the  fiscal quarter  ending September  30, 1995  have been  delivered, the LIBOR
Spread will be  0.875%. Thereafter,  the LIBOR Spread  will be  adjusted as  set
forth below.

</TABLE>

    Changes,  if any, to the  LIBOR Spread and Commitment  Fee will occur on the
earlier of  (i) the  date of  delivery to  the agent  of the  Debt/EBITDA  Ratio
certificate  for such fiscal quarter and (ii)  the date of delivery of financial
statements relating to such fiscal quarter.

   
    In addition to  the interest rate  mechanism described above,  a bid  option
("Bid  Option") is  provided under  the New  Credit Agreement  on an uncommitted
basis through a competitive auction mechanism. The Corporation is not obliged to
accept any bids submitted. The Corporation has the option of inviting the  Banks
to  submit bids (via  Chemical) for advances  ("Competitive Bid Loans"). Bidding
may be requested either on the basis of: (i) a margin relative to LIBOR, or (ii)
a fixed rate. Bids may be  requested for periods of up  to six months but in  no
event later than the maturity date of the facility. The Bid Option may result in
additional interest expense savings to the Corporation.
    

   
    "Alternate Base Rate" means a rate per annum (rounded upwards, if necessary,
to  the next 1/16 of 1%) equal to the greatest of (i) the rate from time to time
publicly   announced    by    Chemical    in    New    York    City    as    its
    

                                       36
<PAGE>
prime  rate,  (ii) the  product  of the  secondary  market rate  for three-month
certificates of deposit from time to time and Statutory Reserves (as defined  in
the  New Credit Agreement) and the Assessment Rate (as defined in the New Credit
Agreement) plus 1.0% and (iii) the federal funds rate from time to time plus 1/2
of 1.0%.

   
    "LIBOR" means an interest rate per annum  determined by the agent to be  the
arithmetic  average of the rates designated  as "LIBO" on Telerate screen number
3750 USD-LIBOR-BBA (rounded upwards,  if necessary, to the  nearest 1/16 of  1%)
for  deposits with a  maturity comparable to a  1-, 2-, 3-  or 6- month interest
period offered in immediately available funds in the London interbank market  at
approximately 11:00 a.m., London time, 2 business days prior to the commencement
of such interest period.
    

FEES

   
    The  Corporation  will  pay  a  commitment  fee  quarterly  in  arrears. The
commitment fee will be calculated based upon a rate per annum equal to the  then
applicable  number  of basis  points  (expressed as  a  percentage) tied  to the
Debt/EBITDA Ratio of the Corporation for the then most recently ended period  of
four consecutive fiscal quarters.
    

SECURITY

   
    The  New Credit Facility is  secured by a pledge  of the outstanding capital
stock of the  Corporation's significant domestic  subsidiaries, which  initially
include  U.S. Gypsum,  USG Interiors,  L&W Supply  and USG  Foreign Investments,
Ltd.. Such security will be  permanently released once the Corporation's  senior
public  debt is rated "Investment Grade" (a rating of BBB- or higher by Standard
& Poor's Ratings Group and Baa3  or higher by Moody's Investors Service,  Inc.).
See "Description of Collateral Trust."
    

NEGATIVE COVENANTS

   
    The  New Credit Agreement contains material restrictions on the operation of
the Corporation's business, including, without limitation, covenants  pertaining
to:(i) liens; (ii) sale and leaseback transactions; (iii) investments, PROVIDED,
that  this covenant would  no longer apply once  the Corporation's senior public
debt rating  is Investment  Grade;  (iv) mergers,  consolidations and  sales  of
assets   with  respect  to  the   Corporation  and  material  subsidiaries;  (v)
acquisitions of businesses not related to the building materials industry;  (vi)
dividends,  distributions  and  repurchases  of  stock  and  subordinated  debt;
PROVIDED, that such covenant will cease to be applicable once the  Corporation's
senior  public debt is rated Investment  Grade; (vii) use of proceeds, PROVIDED,
that the use of proceeds arising from the issuance of additional debt and equity
will be at the Corporation's discretion; (viii) debt or guarantees thereof; (ix)
restrictions in other agreements on ability  of subsidiaries to declare and  pay
dividends;  and  (x) financial  covenants  or events  of  default in  other debt
agreements which are  more restrictive than  those contained in  the New  Credit
Agreement. The negative covenants contain certain exceptions to the restrictions
imposed upon the operation of the Corporation's business.
    

FINANCIAL COVENANTS

   
    The New Credit Agreement contains the following financial covenants:
    

    - Debt/EBITDA Ratio will not exceed 4.50 to 1.0; and

    - Interest Coverage Ratio will not be less than 2.25 to 1.0.

Compliance  with these financial  covenants must be  demonstrated quarterly on a
trailing 12 month basis.

   
    "DEBT" at  any  time,  means,  with  respect  to  the  Corporation  and  its
subsidiaries  on a consolidated  basis, without duplication, the  sum of (i) the
aggregate outstanding principal balance of  the Revolving Loans and  Competitive
Bid  Loans  at  such time,  (ii)  the  aggregate principal  amount  of long-term
indebtedness of the Corporation and  its consolidated subsidiaries at such  time
(including the current portion thereof), (iii) the outstanding amount of capital
leases  shown as a liability on  the Corporation's consolidated balance sheet at
such time,  (iv) all  reimbursement  obligations and  other liabilities  of  the
Corporation and its consolidated subsidiaries with respect to letters of credit,
other  than letters of credit issued in  connection with the incurrence of trade
debt, (v)  any  indebtedness incurred  other  than  in the  ordinary  course  of
business,  whether or not for borrowed money,  secured by any lien in respect of
property owned by such person,
    

                                       37
<PAGE>
whether or not such person has assumed or become liable for the payment of  such
indebtedness,  and (vi) any indebtedness (other  than trade debt incurred in the
ordinary course of business), whether or not for borrowed money, with respect to
which such person has become directly or indirectly liable and which  represents
or has been incurred to finance the purchase price (or a portion thereof) of any
property  or  services  or business  acquired  by  the Corporation  or  any such
consolidated  subsidiary,  whether   by  purchase,   consolidation,  merger   or
otherwise,  and (vii)  the aggregate  amount of  all guarantees  with respect to
indebtedness of third parties of the type described in clauses (ii) through (vi)
above at such time.

continuing  operations of the Corporation  and its subsidiaries before interest,
taxes, depreciation, amortization, other income and expense, minority interests,
the impact of fresh  start accounting and other  non-cash adjustments to  income
for  such period PROVIDED that, for purposes  of the period ending September 30,
1995, operating earnings from continuing operations shall not be reduced by  the
$30  million pre-tax charge which occurred in  the fourth fiscal quarter of 1994
in connection with asbestos litigation settlements.
    

   
    "DEBT/EBITDA RATIO" means the ratio, calculated  as of the last day of  each
fiscal  quarter,  of  (i)  Debt  less the  aggregate  amount  of  cash  and cash
equivalents held by the  Corporation and its  consolidated subsidiaries to  (ii)
EBITDA  for the four quarter  period ending on the last  day of such quarter (in
each case as  reflected on the  Corporation's consolidated financial  statements
for such quarter).
    

   
    "INTEREST  COVERAGE RATIO" of the Corporation for any period means the ratio
of (a) EBITDA for such period to (b) the total net consolidated interest expense
of the  Corporation and  its subsidiaries  during  such period  (as shown  on  a
consolidated  income statement  of the Corporation  for such  period prepared in
accordance with GAAP), excluding the  impact of non-cash amortization  resulting
from fresh start accounting during such period.
    

EVENTS OF DEFAULT

   
    The  New Credit  Agreement contains  customary events  of default including,
without limitation, (i)  the failure to  make payments when  due, (ii)  defaults
under  other agreements  or instruments of  indebtedness in  excess of specified
amounts, (iii) noncompliance  with covenants, (iv)  breaches of  representations
and  warranties, (v) bankruptcy, (vi) judgments  in excess of specified amounts,
(vii) impairment of security interests in collateral, and (viii) certain changes
of control.
    

                              DESCRIPTION OF NOTES

   
    The Notes will be issued under an indenture dated as of October 1, 1986 (the
"1986 Indenture"), between the Corporation and Harris Trust and Savings Bank, as
trustee (the "Indenture Trustee"), as supplemented by resolutions adopted by the
Board and an  officer's certificate  delivered in connection  therewith. The  8%
Senior  Notes due 1996 (the  "Senior 1996 Notes"), the  8% Senior Notes due 1997
(the "Senior 1997 Notes"), the  9 1/4% Senior Notes  due 2001 (the "Senior  2001
Notes")  and  the 8  3/4% Sinking  Fund  Debentures due  2017 (the  "Senior 2017
Debentures," and, together with  the Senior 1996 Notes,  the Senior 1997  Notes,
the  Senior  2001 Notes  and the  Notes, the  "Indenture Securities")  were also
issued under the Indenture, as supplemented by resolutions adopted by the  Board
and   officer's  certificates  delivered  in   connection  therewith.  The  1986
Indenture, as supplemented by such Board resolutions and related instruments, is
referred to  herein as  the "Indenture."  Copies of  the Indenture  and  related
instruments  have been filed  as exhibits to the  Registration Statement and are
available  as  described  under  "Available  Information."  Whenever  particular
provisions  or defined  terms of the  Indenture Securities or  the Indenture are
referred to, such provisions or defined terms are deemed incorporated herein  by
reference and such statements are qualified in their entirety by such reference.
As  used in "Description of Notes,"  the "Corporation" means USG Corporation and
does not include its subsidiaries.
    

GENERAL

   
    The Notes are  a series of  securities which are  limited to $150.0  million
aggregate principal amount. The Notes will bear interest at 8 1/2% per annum and
will    mature   on    August   1,    2005.   Interest    on   the    Notes   is
    

                                       38
<PAGE>
   
payable semi-annually  on February  1  and August  1  of each  year,  commencing
February  1, 1996, to the persons in whose names the Notes are registered at the
close of business on the next preceding January  15 or July 15, as the case  may
be. Interest on the Notes shall accrue from August 8, 1995.
    

    Principal (and premium, if any) and interest is payable, and the transfer of
the  Notes is registrable, at the office or agency of the Corporation maintained
for such  purpose in  the City  of  Chicago, State  of Illinois,  currently  the
Corporate  Trust Office of the Indenture Trustee, Harris Trust and Savings Bank,
311 West Monroe Street, Chicago, Illinois 60690; provided, however, that payment
of interest may  be made  at the  option of the  Corporation by  check or  draft
mailed  to the person entitled  thereto as such person's  address appears in the
security register  maintained for  such purpose  pursuant to  the Indenture.  No
service  charge will be made for any transfer or exchange except the Corporation
may require payment of a sum sufficient  to cover any tax or other  governmental
charge payable in connection therewith.

    The  Notes will be  issued in fully  registered form without  coupons and in
denominations of $1,000 and integral multiples thereof.

RANKING AND SECURITY

   
    Upon issuance, the Notes will be  senior obligations of the Corporation  and
will rank pari passu with the Bank Debt and all other existing and future senior
obligations  of the Corporation. The Bank Debt was incurred under the New Credit
Agreement entered into by  the Corporation and certain  banks on July 27,  1995.
Borrowings  under  the New  Credit Agreement,  and  pursuant to  negative pledge
clauses, the Notes and certain other senior obligations of the Corporation, will
share in security interests in the capital stock of certain of the Corporation's
domestic subsidiaries  as  provided  in the  Collateral  Trust  Agreement.  Upon
repayment  of the Bank Debt  and termination of the  commitments of the banks to
make advances under the New Credit Agreement, or upon release of the  collateral
by  the banks  (which the banks  are required  to do if  the Corporation reaches
Investment Grade  Status), the  Notes and  such other  senior indebtedness  will
cease  to be secured. The Notes will  be effectively subordinated to current and
future indebtedness and liabilities of the Corporation's subsidiaries. See "Risk
Factors -- Holding Company Structure; Relative Priority of Debt Claims."
    

    Holders of the Bank Debt primarily  control the operation of the  Collateral
Trust. See "Description of Collateral Trust."

   
OPTIONAL REDEMPTION
    
   
    The  Notes  are  not  subject  to redemption  by  the  Corporation  prior to
maturity.
    

CHANGE OF CONTROL

    Upon the occurrence of a Change of Control, each Holder shall have the right
to require the  Corporation to repurchase  such Holder's Notes,  in whole or  in
part,  in integral multiples of $1,000, pursuant  to the Change of Control Offer
described in the next succeeding paragraph at the Repurchase Price in cash equal
to 100%  of the  aggregate principal  amount thereof,  plus accrued  and  unpaid
interest thereon, if any, to the Change of Control Payment Date.

   
    Within 30 calendar days subsequent to the date of any Change of Control, the
Corporation  will mail a notice to each Holder and to the Trustee stating, among
other things: (i) that a Change of Control has occurred and a Change of  Control
Offer  is being made as described in  this paragraph, and that, although Holders
are not required to tender their Notes, all Notes that are timely tendered  will
be  accepted for payment;  (ii) the Repurchase  Price and the  Change of Control
Payment Date, which  will be a  date occurring no  earlier than 30  days and  no
later than 60 days after the date on which such notice is mailed; (iii) that any
Notes  (or any portion thereof)  accepted for payment pursuant  to the Change of
Control Offer (and duly paid on the  Change of Control Payment Date) will  cease
to  accrue interest after the Change of Control Payment Date; (iv) a description
of the transaction or transactions constituting  the Change of Control; and  (v)
the  procedures that  Holders must  follow in  order to  tender their  Notes for
payment.
    

    In the event the Corporation reaches Investment Grade Status, the  foregoing
Change  of Control provisions  shall no longer  apply, and thereafter  if both a
Designated Event with respect to the Corporation

                                       39

and a Rating Decline in connection  therewith shall occur, the Corporation  will
be  obligated to offer to repurchase any or all  of the Notes at a price in cash
equal to 100% of the principal amount thereof, plus accrued and unpaid  interest
to  the date of repurchase.  If the Corporation effects  defeasance of the Notes
under the Indenture prior to the date  notice of a Rating Decline in  connection
with  a Designated Event is  required, the Corporation will  not be obligated to
make a repurchase offer as a result of such Designated Event and Rating Decline.

    There can be no assurance that the Corporation will be able to fund any such
repurchase of the Notes. The New  Credit Agreement provides that certain  change
of  control events  with respect to  the Corporation would  constitute a default
thereunder. Any  future  credit  agreements  or  other  agreements  relating  to
indebtedness  to  which  the Corporation  becomes  a party  may  contain similar
restrictions and provisions. In the event a  Change of Control occurs at a  time
when  the Corporation is prohibited from purchasing Notes, the Corporation could
seek the consent of  its lenders to  the purchase of Notes  or could attempt  to
refinance  the borrowings that contain such prohibition. If the Corporation does
not obtain such a consent or repay such borrowings, the Corporation will  remain
prohibited  from purchasing  Notes. In such  case, the  Corporation's failure to
purchase  tendered  Notes  would  constitute  an  Event  of  Default  under  the
Indenture.

    If  an offer is made  to repurchase Notes, the  Corporation will comply with
all tender offer  rules, including but  not limited to  Section 14(e) under  the
Exchange Act and Rule 14e-1 thereunder, to the extent applicable to such offer.

    Except  as described above,  the Indenture does  not contain provisions that
permit the Holders of  the Notes to require  that the Corporation repurchase  or
redeem the Notes in the event of a takeover, recapitalization or restructuring.

SINKING FUND

    There will be no mandatory sinking fund payments for the Notes.

BOOK-ENTRY SYSTEM

    The  Notes  will initially  be  issued in  the form  of  one or  more Global
Securities (as defined in the  Indenture) held in book-entry form.  Accordingly,
The Depository Trust Company ("DTC") or its nominees will be the sole registered
holder of the Notes for all purposes under the Indenture.

    Upon  the issuance of a Global Security,  DTC or its nominee will credit the
accounts of persons holding through it with the respective principal amounts  of
the  Notes represented by such Global Security  purchased by such persons in the
offering. Such accounts shall be designated by the Underwriters with respect  to
Notes  placed by the  Underwriters for the  Corporation. Ownership of beneficial
interests in a  Global Security will  be limited to  persons that have  accounts
with   DTC  ("participants")  or   persons  that  may   hold  interests  through
participants. Ownership  of  beneficial interest  by  participants in  a  Global
Security  will be shown on, and the  transfer of that ownership interest will be
effected only  through, records  maintained  by DTC  for such  Global  Security.
Ownership  of beneficial interests in such  Global Security by persons that hold
through participants  will be  shown  on, and  the  transfer of  that  ownership
interest  within  such  participant  will  be  effected  only  through,  records
maintained by  such participant.  The laws  of some  jurisdictions require  that
certain  purchasers of securities  take physical delivery  of such securities in
definitive form. Such limits  and such laws may  impair the ability to  transfer
beneficial interests in a Global Security.

    Payment  of principal and  interest on Notes represented  by any such Global
Security will be made  to DTC or its  nominee, as the case  may be, as the  sole
registered  owner and the sole  holder of the Notes  represented thereby for all
purposes under the Indenture. None of the Corporation, the Trustee, any agent of
the Corporation, or the Underwriters  will have any responsibility or  liability
for  any aspect  of DTC's  records relating  to or  payments made  on account of
beneficial ownership interests in  a Global Security  representing any Notes  or
for maintaining, supervising, or reviewing any of DTC's records relating to such
beneficial ownership interests.

    The  Corporation has been advised by DTC that upon receipt of any payment of
principal of or interest on any Global Security, DTC will immediately credit, on
its book-entry registration and transfer system, the

                                       40
<PAGE>
accounts of  participants  with  payments  in  amounts  proportionate  to  their
respective  beneficial interests in the principal amount of such Global Security
as shown on the records of DTC. Payments by participants to owners of beneficial
interests in a Global Security held  through such participants will be  governed
by  standing  instructions  and customary  practices  as  is now  the  case with
securities held for customer  accounts registered in "street  name" and will  be
the sole responsibility of such participants.

    A  Global Security  may not  be transferred except  as a  whole by  DTC to a
nominee of DTC. A Global Security is exchangeable for certificated Notes only if
(i) DTC notifies the Corporation that it is unwilling or unable to continue as a
Depository for  such Global  Security or  if  at any  time DTC  ceases to  be  a
clearing agency registered under the Securities Exchange Act of 1934, as amended
(the  "Exchange Act"), (ii) the Corporation executes and delivers to the Trustee
a notice that such  Global Security shall be  so transferable, registrable,  and
exchangeable, and such transfers shall be registrable, or (iii) there shall have
occurred  and be  continuing an  Event of  Default or  an event  which, with the
giving of notice or lapse of time or both, would constitute an Event of  Default
with  respect  to the  Notes  represented by  such  Global Security.  Any Global
Security that is exchangeable for  certificated Notes pursuant to the  preceding
sentence  will be transferred to, and registered and exchanged for, certificated
Notes in authorized denominations and registered in such names as the Depository
holding such Global  Security may  direct. Subject  to the  foregoing, a  Global
Security  is not exchangeable, except for a Global Security of like denomination
to be registered in the name of the Depository or its nominee. In the event that
a Global Security becomes exchangeable for certificated Notes, (i)  certificated
Notes will be issued only in fully registered form in denominations of $1,000 or
integral multiples thereof, (ii) payment of principal, any repurchase price, and
interest  on the  certificated Notes  will be payable,  and the  transfer of the
certificated Notes  will  be  registerable  at  the  office  or  agency  of  the
Corporation  maintained for such  purposes, and (iii) no  service charge will be
made for any  registration of transfer  or exchange of  the certificated  Notes,
although  the Corporation may require  payment of a sum  sufficient to cover any
tax or governmental charge imposed in connection therewith.

    So long as  the Depository for  a Global  Security, or its  nominee, is  the
registered  owner of such  Global Security, such Depository  or such nominee, as
the case  may be,  will be  considered the  sole owner  or holder  of the  Notes
represented by such Global Security for the purposes of receiving payment of the
Notes, receiving notices, and for all other purposes under the Indenture and the
Notes.  Beneficial interest  in Notes will  be evidenced only  by, and transfers
thereof will be effected only through, records maintained by the Depository  and
its  participants.  Cede  &  Co.  has  been  appointed  as  the  nominee  of the
Depository. Except as provided above, owners of beneficial interest in a  Global
Security  will not be entitled to and will not be considered the holders thereof
for any  purposes  under  the  Indenture.  Accordingly,  each  person  owning  a
beneficial  interest in  a Global  Security must rely  on the  procedures of the
Depository, and, if such person is not  a participant, on the procedures of  the
participant  through which such person owns its interest, to exercise any rights
of a holder under the Indenture. The Corporation understands that under existing
industry practice, in  the event  that the  Corporation requests  any action  of
holders  or that an owner of a  beneficial interest in a Global Security desires
to give or take any action which a holder is entitled to give or take under  the
Indenture,  the Depository would authorize the participants holding the relevant
beneficial interest to  give or  take such  action and  such participants  would
authorize  beneficial owners  owning through such  participants to  give or take
such action or would  otherwise act upon the  instructions of beneficial  owners
owning through them.

    DTC  has advised the Corporation that DTC is a limited-purpose trust company
organized under  the Banking  Law of  the State  of New  York, a  member of  the
Federal  Reserve System, a "clearing corporation"  within the meaning of the New
York Uniform  Commercial Code,  and  a "clearing  agency" registered  under  the
Exchange  Act. DTC was created to hold the securities of its participants and to
facilitate the clearance  and settlement  of securities  transactions among  its
participants  in  such  securities  through  electronic  book-entry  changes  in
accounts of the participants, thereby eliminating the need for physical movement
of securities certificates.  DTC's participants include  securities brokers  and
dealers   (including  the   Underwriters),  banks,   trust  companies,  clearing
corporations,  and   certain   other   organizations  some   of   whom   (and/or

                                       41
<PAGE>
their  representatives)  own  DTC. Access  to  DTC's book-entry  system  is also
available to others, such as banks,  brokers, dealers, and trust companies  that
clear  through or maintain  a custodial relationship  with a participant, either
directly or indirectly.

CERTAIN RESTRICTIVE COVENANTS

    The Indenture will provide that the following restrictive covenants will  be
applicable   to  the  Corporation  unless  and  until  the  Corporation  reaches
Investment Grade  Status. After  the Corporation  has reached  Investment  Grade
Status,  and notwithstanding that the Corporation's  Debt Rating may later cease
to be rated Investment Grade by either  S&P or Moody's or both, the  Corporation
will  be released from  its obligations to  comply with each  of the restrictive
covenants described below, except for "Limitation on Indebtedness,"  "Limitation
on  Restricted  Subsidiary  Indebtedness and  Preferred  Stock,"  "Limitation on
Secured Indebtedness of  the Corporation  and its  Restricted Subsidiaries"  and
"Limitation  on Sale  and Leaseback  Transactions." The  Corporation will remain
obligated to  comply  with  certain provisions  described  in  "Restrictions  on
Merger"  and certain other covenants that  are not described below upon reaching
Investment Grade Status. The  Corporation will also  remain obligated to  comply
with certain provisions described under "Change of Control" above.

    LIMITATION   ON  INDEBTEDNESS.    The  Corporation  will  not,  directly  or
indirectly, Incur any  Indebtedness unless,  immediately after the  date of  the
Incurrence  of such  Indebtedness and after  giving effect to  the Incurrence of
such Indebtedness and the receipt and application of the proceeds thereof as  if
such  Indebtedness had  been Incurred  and the  proceeds thereof  applied on the
first day of the Determination Period, the Consolidated Interest Coverage  Ratio
of the Corporation exceeds 2.0 to 1.

   
    Notwithstanding  the  foregoing,  the Corporation  may  Incur  the following
Indebtedness (although any Indebtedness  so Incurred shall  be included, to  the
extent  outstanding at the Transaction Date,  in any subsequent determination of
the Consolidated Interest Coverage Ratio): (i) Indebtedness under the New Credit
Agreement; (ii) Indebtedness outstanding on  the Issue Date; (iii)  Indebtedness
outstanding  under the Notes; (iv) Indebtedness of the Corporation in respect of
Capital Lease Obligations and Sale and Leaseback Transactions Incurred after the

aggregate  amount  of Priority  Indebtedness  outstanding would  not  exceed the
Priority Indebtedness Basket;  (v) Indebtedness under  Interest Rate  Protection
Agreements,  provided that the obligations under  such agreements are related to
payment obligations on  Indebtedness otherwise  permitted by the  terms of  this
covenant;  (vi) Indebtedness of  the Corporation to  any wholly owned Restricted
Subsidiary of the Corporation  (but only so  long as such debt  is held by  such
wholly  owned Restricted Subsidiary);  (vii) Permitted Refinancing Indebtedness;
(viii) Indebtedness  incurred  in connection  with  a prepayment  of  the  Notes
pursuant  to a Change of Control, provided that (A) the principal amount of such
Indebtedness does not exceed the principal amount of the Notes prepaid plus  all
interest  accrued  thereon and  all related  fees,  expenses and  redemption and
repurchase premiums related thereto (including  any payments made in  connection
with  procuring any required lender or  similar consents); (B) such Indebtedness
has an Average Life equal to or  greater than the remaining Average Life of  the
Notes; and (C) such Indebtedness does not mature prior to the Stated Maturity of
the Notes; and (ix) Indebtedness not otherwise permitted to be Incurred pursuant
to this paragraph or the preceding paragraph in an aggregate principal amount at
any one time outstanding not to exceed $125 million.
    

    LIMITATION  ON RESTRICTED SUBSIDIARY INDEBTEDNESS  AND PREFERRED STOCK.  The
Corporation will  not  permit  any  of its  Restricted  Subsidiaries  to  Incur,
directly  or indirectly, any Indebtedness or  issue any Preferred Stock, except:
(i) Indebtedness outstanding on the  Issue Date; (ii) Indebtedness or  Preferred
Stock  issued to  and held  by the  Corporation or  any wholly  owned Restricted
Subsidiary of  the  Corporation  (but  only so  long  as  such  Indebtedness  or
Preferred  Stock  is  held or  owned  by  the Corporation  or  any  wholly owned
Restricted Subsidiary of  the Corporation); (iii)  Indebtedness of a  Restricted
Subsidiary  in  respect  of Capital  Lease  Obligations and  Sale  and Leaseback

Agreements,  provided that the obligations under  such agreements are related to

                                       42
<PAGE>
Subsidiary;  (vi)  Indebtedness  not  otherwise  permitted  to  be  Incurred  or
Preferred Stock not otherwise permitted to be issued pursuant to this  paragraph
if after giving effect to the Incurrence of such Indebtedness or the issuance of
such  Preferred Stock the aggregate  amount of Priority Indebtedness outstanding
would not exceed the Priority  Indebtedness Basket; provided that the  aggregate
amount of Indebtedness Incurred or Preferred Stock issued by Domestic Restricted
Subsidiaries  pursuant to this clause  (vi) shall not exceed  $75 million at any
one time outstanding; and (vii) Indebtedness Incurred or Preferred Stock  issued
in  exchange for, or the  proceeds of which are  used to Refinance, Indebtedness
referred to  in  clause (i)  of  this paragraph,  to  the extent  that  (A)  the
principal amount of such Indebtedness or the liquidation value of such Preferred
Stock  so Incurred or issued does not exceed the principal amount or liquidation
value of the Indebtedness or Preferred Stock so exchanged or Refinanced plus all
interest or  dividends  accrued  thereon  and all  related  fees,  expenses  and
redemption  and repurchase premiums  (including any payments  made in connection
with procuring any required lender or similar consents), (B) the Indebtedness so
Incurred or Preferred Stock so issued has a Stated Maturity or final  redemption
date later than the Stated Maturity or final redemption date (if any) of, and an
Average  Life that is longer  than that of, the  Indebtedness or Preferred Stock
being exchanged or Refinanced and (C) the Indebtedness so Incurred or  Preferred
Stock  so issued has no  greater recourse to the  Property of the Corporation or

exchanged or refinanced.

    Any  Indebtedness  Incurred  or  Preferred  Stock  issued  pursuant  to  the
preceding  paragraph  will  be  included,  to  the  extent  outstanding  at  the
Transaction  Date, in any subsequent  determination of the Consolidated Interest
Coverage Ratio.

   
    The Corporation  will  not,  and  will not  permit  any  of  its  Restricted
Subsidiaries  to, take  any action  or enter into  any transaction  or series of
transactions that  would result  in a  Person becoming  a Restricted  Subsidiary
(whether through an acquisition, the redesignation of an Unrestricted Subsidiary
or  otherwise) unless, after giving effect to such action, transaction or series
of transactions, on a pro forma basis, (i) the Corporation could Incur at  least
$1.00  of  additional Indebtedness  pursuant to  the  first paragraph  under "--
Limitation on Indebtedness" and (ii) such subsidiary could then Incur,  pursuant
to  clauses (ii) through (vi) of the  first paragraph above, all Indebtedness as
to which it is obligated at such time.
    

    LIMITATIONS ON RESTRICTED PAYMENTS.  The Corporation will not, and will  not
permit  any of its Restricted Subsidiaries  to, directly or indirectly, make any
Restricted Payment if, at the  time of and after  giving effect to the  proposed
Restricted  Payment (i)  any Default  or Event  of Default  has occurred  and is
continuing, (ii) the Corporation  could not incur at  least $1.00 of  additional
Indebtedness  under the first  paragraph of "--  Limitation on Indebtedness", or
(iii) the aggregate amount expended or declared for all Restricted Payments from
the Issue Date (the Fair Market Value of the amount so expended or committed, if
other than in cash, to be determined in good faith by the Board of Directors  of
the  Corporation) exceeds the sum  of (A) 50% of  the aggregate Consolidated Net
Income of the Corporation  (or, if Consolidated Net  Income shall be a  deficit,
minus  100% of such  deficit) commencing on  the last day  of the fiscal quarter
immediately preceding the Issue Date  and ending on the  last day of the  fiscal
quarter  immediately preceding the date of  such Restricted Payment, (B) 100% of
the aggregate net proceeds, including cash and the Fair Market Value of Property
other than cash, received by the  Corporation subsequent to the Issue Date  from
capital  contributions from its stockholders or from the issuance or sale (other
than to a Subsidiary) of  Qualified Capital Stock of  the Corporation or of  any
convertible  securities  or debt  obligations  issued on  or  after the  date of
issuance of the Notes which have been converted into, exchanged for or satisfied
by the issuance of Qualified Capital Stock and (C) $175.0 million (collectively,
the "Restricted Payment Basket").

    The foregoing limitations do not prevent  the Corporation from (i) paying  a
dividend  on its Capital Stock  within 60 days after  declaration thereof if, on
the  declaration  date,  the  Corporation  could  have  paid  such  dividend  in
compliance  with the Indenture;  (ii) acquiring shares of  its Capital Stock (1)
solely in exchange for other shares of its Capital Stock (other than  Redeemable
Stock),  (2) to eliminate fractional shares for up to an aggregate consideration
in any fiscal year of the Corporation not to exceed $10.0 million, (3)  pursuant
to  an order of  a court of competent  jurisdiction, or (4)  from an employee or
director of  the  Corporation in  connection  with repurchase  provisions  under
employee  or director  stock option  and stock  purchase agreements  or plans or
other agreements to compensate employees or directors of the Corporation, but in

                                       43
<PAGE>
   
no event may such acquisition  of its shares by the  Corporation be for a  price
greater  than  the higher  of  fair market  value and  the  price at  which such
securities were sold  to such  employee or  director by  the Corporation;  (iii)
purchasing  or redeeming Indebtedness which is contractually subordinated to the
Notes in exchange for, or out  of the proceeds of, the substantially  concurrent
(1)  sale or  issuance of  Capital Stock  (other than  Redeemable Stock)  of the
Corporation, or (2)  incurrence of Indebtedness  of the Corporation  that is  at
least  as contractually  subordinated in  right of payment  to the  Notes as the
Indebtedness so  refinanced and  has a  Stated Maturity  later than  the  Stated
Maturity  of the Notes  and an Average  Life greater than  the remaining Average
Life of the Notes; (iv) the distribution or redemption by the Corporation of any
rights to purchase capital  stock of the Corporation  or any other Person  which
rights  are or were issued  as part of a  shareholder rights plan; provided that
any such redemption will be  at a price not to  exceed $0.01 per right; (v)  the
making  of  any payment  required  pursuant to  the  Corporation's 1988  plan of
recapitalization or the Corporation's 1993 plan of reorganization; provided that
such payments shall not exceed $5 million in the aggregate; and (vi)  purchasing
or  redeeming up to 25% of the stock  of any Restricted Subsidiary to the extent
the Restricted  Payment  Basket is  not  exceeded. Further,  (x)  the  foregoing
restrictions  do not prevent CGC Inc. from  paying ordinary dividends and (y) in
the case of a  Qualified Receivables Transaction,  the foregoing limitations  do
not  prevent a Receivables Subsidiary from acquiring equity interests of a trust
or other  person  established by  such  Receivables Subsidiary  to  effect  such
Qualified Receivables Transaction.
    

    The  payments permitted to be made  pursuant to clauses (ii)(1), (iii), (iv)
and (v) of the preceding paragraph shall be excluded for purposes of any  future
calculations  of  the  aggregate  amount  expended  or  declared  for Restricted
Payments. The payments permitted  to be made pursuant  to clauses (i),  (ii)(2),
(ii)(3), (ii)(4), and (vi) above, and payments of dividends permitted to be made
pursuant  to clause (x) above by CGC Inc.  (but only to the extent such payments
are made to a Person other  than the Corporation or its wholly-owned  Restricted
Subsidiaries),  shall be included for purposes of any future calculations of the
aggregate amount expended or declared for Restricted Payments.

    LIMITATION UPON SECURED INDEBTEDNESS OF  THE CORPORATION AND ITS  RESTRICTED
SUBSIDIARIES.  So long as any of the Notes are outstanding, the Corporation will
not  itself,  and  will  not  permit any  Restricted  Subsidiary  to,  Incur any
Indebtedness secured by  a Lien on  any Principal Operating  Property or on  any
shares   of  stock  or  Indebtedness   of  any  Restricted  Subsidiary,  without
effectively providing  that the  Notes  (together with,  if the  Corporation  so
determines,  any other Senior Indebtedness of the Corporation or Indebtedness of
such Restricted Subsidiary then existing or thereafter created) shall be secured
equally and  ratably with  (or,  at the  Corporation's  option, prior  to)  such
secured  Indebtedness so long as such  secured Indebtedness shall be so secured,
unless, after giving effect thereto, Priority Indebtedness would not exceed  the
Priority Indebtedness Basket. This restriction does not apply to, and there will
be excluded from secured Indebtedness in any computation under such restriction,
Indebtedness  secured by (i) Liens on property of,  or on any shares of stock or
Indebtedness of,  any  Person  existing  at  the  time  such  Person  becomes  a
Restricted  Subsidiary; (ii) Liens in favor of the Corporation or a wholly owned
Restricted Subsidiary; (iii)  Liens in  favor of governmental  bodies to  secure
progress, advance or other payments pursuant to any contract or provision of any
statute;  (iv) certain Liens created (A) in the ordinary course of business, (B)
in connection with taxes,  assessments or other governmental  charges or (C)  in
connection  with  legal  proceedings; (v)  Liens  on, and  limited  to, property
(including leasehold estates), shares of  stock or Indebtedness existing at  the
time   of  acquisition   thereof  (including   acquisition  through   merger  or
consolidation and not put  in place in contemplation  of the transaction);  (vi)
purchase  money and construction  Liens which are  entered into within specified
time limits;  (vii)  Liens  on the  assets  of  a Receivables  Subsidiary  in  a
Qualified   Receivables   Transaction;  and   (viii)  any   extension,  renewal,
replacement or refunding of  any Lien referred to  in the foregoing clauses  (i)
through (vii), inclusive.

    LIMITATION  UPON SALE  AND LEASEBACK  TRANSACTIONS.  So  long as  any of the
Notes are outstanding, the Corporation will not itself, and will not permit  any
Restricted  Subsidiary to,  enter into any  Sale and  Leaseback Transaction with
respect to any Principal  Operating Property owned by  them while the Notes  are
outstanding.

    This  restriction does not  apply to any Sale  and Leaseback Transaction if:
(i) the Corporation or such Restricted Subsidiary could mortgage such  Principal
Operating Property under the restrictions set forth

                                       44
<PAGE>
under  "-- Limitation  Upon Secured Debt  of the Corporation  and its Restricted
Subsidiaries" above in an amount equal to the Attributable Value with respect to
such Sale and  Leaseback Transaction  without equally and  ratably securing  the
Indenture  Securities;  (ii)  within 120  days  after  the sale  or  transfer is
completed, the Corporation or a Restricted Subsidiary applies to the  retirement
of  Senior  Indebtedness  of the  Corporation  or Indebtedness  of  a Restricted
Subsidiary an amount equal to the greater of (A) the net proceeds of the sale of
the Principal Operating  Property leased  or (B) the  fair market  value of  the
Principal   Operating  Property  leased  at  the  time  of  entering  into  such
arrangement; or  (iii)  such  arrangement  is  between  the  Corporation  and  a
wholly-owned Restricted Subsidiary or between Restricted Subsidiaries.

   
    TRANSACTIONS  WITH AFFILIATES.   Neither the Corporation  nor any Restricted
Subsidiary will be permitted to: (i) sell, lease, transfer, or otherwise dispose
of any of its properties, assets, or securities to; (ii) purchase any  property,
assets,  or securities from; or (iii) enter into any contract or agreement with,
or for the benefit of, an Affiliate, within the meaning of Rule 405  promulgated
by  the Commission under the Securities Act,  of the Corporation or a subsidiary
of  the  Corporation   (an  "Affiliate  Transaction"),   other  than   Affiliate
Transactions  (A) in the  ordinary course of business  with Affiliates which are
directly or  indirectly controlled  by  the Corporation  and  are engaged  in  a
similar  or complementary line of business,  which Affiliate Transactions do not
exceed: (a) $25.0 million in any one Affiliate Transaction or series of  related
Affiliate  Transactions unless  a majority of  the disinterested  members of the
Board of Directors of the Corporation determines that such Affiliate Transaction
or series  of Affiliate  Transactions is  on  terms not  less favorable  to  the
Corporation  or such  Restricted Subsidiary  than those  that would  apply to an
arms-length transaction with an unaffiliated party and (b) $100.0 million in any
one Affiliate Transaction or series of related Affiliate Transactions unless the
test set forth in clause  (a) has been satisfied and  the Board of Directors  of
the  Corporation shall  have been  advised by  an independent  financial advisor
that, in the opinion  of such advisor, such  Affiliate Transaction or series  of
Affiliate  Transactions  is  fair,  from  a  financial  point  of  view,  to the
Corporation or such Restricted  Subsidiary; and (B)  with Affiliates other  than
those  described in clause (A) above, which  in the aggregate do not exceed: (a)
$5.0 million in  any one Affiliate  Transaction or series  of related  Affiliate
Transactions unless an officer of the Corporation certifies in writing that such
Affiliate  Transaction or series of Affiliate  Transactions is on terms not less
favorable to the Corporation or such Restricted Subsidiary than those that would
apply to  an  arms-length transaction  with  an unaffiliated  party;  (b)  $25.0
million  in  any  one  Affiliate  Transaction  or  series  of  related Affiliate
Transactions unless a  majority of  the disinterested  members of  the Board  of
Directors  of  the Corporation  determines  that such  Affiliate  Transaction or
series of  Affiliate  Transactions  is  on  terms  not  less  favorable  to  the
Corporation  or such  Restricted Subsidiary  than those  that would  apply to an
arms-length transaction with an unaffiliated party and (c) $100.0 million in any
one Affiliate Transaction or series of related Affiliate Transactions unless the
test set forth in clause  (b) has been satisfied and  the Board of Directors  of
the  Corporation shall  have been  advised by  an independent  financial advisor
that, in the opinion  of such advisor, such  Affiliate Transaction or series  of
Affiliate  Transactions  is  fair,  from  a  financial  point  of  view,  to the
Corporation or  such  Restricted  Subsidiary;  provided  that  (x)  transactions
between or among the Corporation and/or its wholly owned Restricted Subsidiaries
will  not be  considered Affiliate Transactions  and (y)  transactions between a
Receivables Subsidiary  and  any  Person  as part  of  a  Qualified  Receivables
Transaction  will not  be considered an  Affiliate Transaction, but  only to the
extent such transactions are solely in connection with the Qualified Receivables
Transaction. In addition, any other Affiliate Transactions that are not  covered
by  clause (A) or (B) of the preceding sentence by reason of their size shall be
on terms not  less favorable to  the Corporation or  such Restricted  Subsidiary
than  those that would apply to  an arms-length transaction with an unaffiliated
party.
    

   
    The foregoing limitations do not apply  to (i) transactions with an  officer
or director of the Corporation or any Subsidiary of the Corporation entered into
in  the ordinary course  of business regarding  compensation or employee benefit
arrangements, (ii) transactions  between the  Corporation and  its wholly  owned
Restricted  Subsidiaries or  among its  wholly owned  Restricted Subsidiaries or
(iii) transactions  in the  ordinary  course of  business consistent  with  past
practice  between the Corporation  and CGC Inc.,  so long as  CGC Inc. remains a
Restricted Subsidiary.
    

    LIMITATION ON ASSET SALES.   The Corporation will  not, and will not  permit
any  Restricted  Subsidiary  to,  consummate  any  Asset  Sale  unless:  (i) the
Corporation   or   such   Restricted   Subsidiary,   as   the   case   may   be,

                                       45
<PAGE>
receives  consideration at least equal to the  Fair Market Value of the Property
disposed of  and  (ii)  at  least  70% of  the  consideration  received  by  the
Corporation  or such Restricted Subsidiary  for such Property is  in the form of
cash, cash equivalents, Indebtedness assumed by the buyer with respect to  which
the  Corporation and its remaining Restricted  Subsidiaries are no longer liable
and trade payables  assumed by the  buyer; provided that  the Corporation  must,
within  270 days of such  Asset Sale, at the  Corporation's option, (1) reinvest
(or cause a Restricted Subsidiary to reinvest)  an amount equal to the Net  Cash
Proceeds  (or any  portion thereof) from  such disposition  in Additional Assets
and/or (2) apply an amount equal to  such Net Cash Proceeds to the repayment  of
Senior  Indebtedness or Indebtedness of Restricted Subsidiaries and/or (3) offer
to apply an amount equal to such Net Cash Proceeds to the repayment of the Notes
and repurchase  any Notes  properly tendered  in acceptance  of such  Prepayment
Offer  on a pro rata basis  at a purchase price at  least equal to 100% of their
principal amount plus interest  accrued to the date  of such repurchase. In  the
event the remaining Net Cash Proceeds resulting from any Asset Sale after giving
effect  to  the purchase  of Additional  Assets and/or  the repayment  of Senior
Indebtedness or Indebtedness  of Restricted  Subsidiaries, are  less than  $25.0
million,  the application of an amount equal to such remaining Net Cash Proceeds
to a pro rata offer to repurchase the  Notes may be deferred until such time  as
such remaining Net Cash Proceeds, together with remaining Net Cash Proceeds from
any  prior or  subsequent Asset Sales  not otherwise applied  in accordance with
this paragraph, are  at least equal  to $25.0  million. To the  extent that  any
portion  of the amount  of Net Cash  Proceeds remains after  compliance with the
foregoing and  provided that  all Holders  have been  given the  opportunity  to
tender  their  Notes  for  repurchase  as  provided  in  clause  (3)  above, the
Corporation or  such Restricted  Subsidiary may  use such  remaining amount  for
general corporate purposes.

    Within five Business Days after 270 days from the date of an Asset Sale, the
Corporation  shall, if it chooses (or is  obligated) to apply an amount equal to
any remaining Net Cash  Proceeds (or any  portion thereof) to  fund an offer  to
repurchase  the Notes,  send a written  Prepayment Offer  Notice, by first-class
mail, to the Holders of the Notes.  The Prepayment Offer Notice will also  state
(i)  that  the  Corporation  is  offering  to  purchase  Notes  pursuant  to the
provisions of  the Indenture  described  herein under  "-- Limitation  on  Asset
Sales",  (ii) that any Notes (or any  portion thereof) accepted for payment (and
duly paid on the Purchase Date) pursuant  to the Prepayment Offer will cease  to
accrue  interest  after the  Purchase  Date, (iii)  the  Expiration Date  of the
Prepayment Offer,  which  will  be,  subject to  any  contrary  requirements  of
applicable  law, not less than 30  days nor more than 60  days after the date of
such Prepayment Offer, (iv) a Purchase Date (which shall be the settlement  date
for  the purchase  of Notes and  shall be  within three business  days after the
Expiration Date), (v) the  aggregate principal amount of  Notes to be  purchased
and  the purchase price thereof and (vi)  a description of the procedure which a
Holder must follow  and any  other information necessary  to tender  all or  any
portion of such Holder's Notes.

    LIMITATION  ON DIVIDEND AND OTHER  PAYMENT RESTRICTIONS AFFECTING RESTRICTED
SUBSIDIARIES.  The Corporation will not be permitted to, and will not permit any
Restricted Subsidiary to, directly or  indirectly, create or otherwise cause  or
suffer  to exist any encumbrance  or restriction (other than  pursuant to law or
regulation) on the ability of any Restricted Subsidiary to (i) pay any  dividend
on,  or make any other distribution on account  of, its capital stock or pay any
Indebtedness owed to the Corporation or a Restricted Subsidiary; (ii) make loans
or advances to the Corporation or a Restricted Subsidiary; or (iii) transfer any
of its property or assets to the Corporation or any other Restricted Subsidiary,
except for (a) restrictions in agreements existing as of the date of issuance of
the Notes; (b) restrictions in the Collateral Trust Agreement; (c)  restrictions
on   Foreign  Restricted  Subsidiaries  relating   to  Project  Financings;  (d)
restrictions on  Foreign  Joint Ventures;  (e)  restrictions on  Domestic  Joint
Ventures, but only to the extent that the amounts invested by the Corporation in
the  entities subject to  such restrictions do  not exceed $25.0  million in the
aggregate at any one time; (f) Indebtedness or other contractual requirements of
a Receivables  Subsidiary  solely in  connection  with a  Qualified  Receivables
Transaction,  provided  that such  restrictions apply  only to  such Receivables
Subsidiary; (g) any encumbrance or restriction pursuant to an agreement relating
to an acquisition of  Property, so long as  the encumbrances or restrictions  in
any  such  agreement relate  solely to  the  Property so  acquired and  were not
created in  connection with  or in  anticipation of  such acquisition;  (h)  any
encumbrance  or  restriction  relating  to any  Indebtedness  of  any Restricted
Subsidiary at the date on which  such Restricted Subsidiary was acquired by  the
Corporation or any Restricted Subsidiary (other than

                                       46
<PAGE>
Indebtedness  issued  by such  Restricted Subsidiary  in  connection with  or in
anticipation of its acquisition); (i) any encumbrance or restriction pursuant to
an agreement effecting a permitted  refinancing of Indebtedness issued  pursuant
to  an agreement referred to in the foregoing  clauses (a), (b), (g) and (h), so
long as  the encumbrances  and restrictions  contained in  any such  refinancing
agreement  are  no  more  restrictive  than  the  encumbrances  and restrictions
contained in such agreements; (j) customary provisions restricting subletting or
assignment of leases and customary provisions in other agreements that  restrict
assignment  of such agreements or rights  thereunder; (k) any restriction on the
sale or other disposition of assets or  Property securing debt as a result of  a
lien  of the kind set forth in  clauses (i)-(vii) of "-- Limitation Upon Secured
Indebtedness  of  the   Corporation  and  its   Restricted  Subsidiaries,"   (l)
restrictions  in agreements with Foreign Restricted Subsidiaries taking the form
of  net  worth  maintenance  tests  and  similar  financial  covenants  and  (m)
agreements  for the  purchase of synthetic  gypsum entered into  in the ordinary
course of business consistent with past practice.

    RESTRICTED AND UNRESTRICTED SUBSIDIARIES.   The Corporation may designate  a
subsidiary  (including  a  newly formed  or  newly acquired  subsidiary)  of the
Corporation or any of its Restricted Subsidiaries as an Unrestricted  Subsidiary
if (i) such subsidiary does not have any obligations which, if in Default, would
result  in  a cross  default on  Indebtedness  of the  Corporation and  (a) such
subsidiary has  total assets  of $1,000  or  less, or  (b) such  designation  is
effective  immediately  upon such  Person becoming  a  subsidiary of  either the
Corporation or any of its Restricted  Subsidiaries or (ii) such subsidiary is  a
Receivables  Subsidiary or a captive insurance  company. Unless so designated as
an Unrestricted  Subsidiary,  any  Person  that  becomes  a  subsidiary  of  the
Corporation  or  any of  its Restricted  Subsidiaries shall  be classified  as a
Restricted Subsidiary  thereof. Except  as  provided in  clause (i)(a)  of  this
paragraph,  no  Restricted Subsidiary  may  be redesignated  as  an Unrestricted
Subsidiary. An  Unrestricted  Subsidiary may  be  redesignated as  a  Restricted
Subsidiary.  The designation  of an Unrestricted  Subsidiary or  removal of such
designation shall be  made by the  Board of  Directors of the  Corporation or  a
committee  thereof pursuant to  a certified resolution  delivered to the Trustee
and shall be  effective as  of the date  specified in  the applicable  certified
resolution,  which shall not be  prior to the date  such certified resolution is
delivered to the Trustee.

RESTRICTIONS ON MERGER

   
    So long as any  Notes are outstanding, the  Corporation will not, except  as
described  below, consolidate  with or  merge into any  other Person  or sell or
transfer all or substantially all of its properties and assets to another Person
unless (i) the surviving  entity is a company  organized and existing under  the
laws  of the United States of America  or a state thereof and expressly assumes,
by supplemental  indenture satisfactory  to the  Trustee, the  due and  punctual
payment  of the principal of (and premium, if any) and interest on all the Notes
and the  due  and punctual  performance  and  observance of  all  covenants  and
conditions  of the  Corporation in  the Indenture;  (ii) immediately  before and
after giving effect to such transaction  or series of related transactions on  a
pro forma basis, no Default or Event of Default (and no event that, after notice
or  lapse  of time,  or  both, would  become an  Event  of Default),  shall have
occurred and  be  continuing; (iii)  immediately  after giving  effect  to  such
transaction  or series of transactions on  a pro forma basis (including, without
limitation,  any  Indebtedness  Incurred  or  anticipated  to  be  Incurred   in
connection with such transaction or series of transactions), the Corporation (or
the  surviving entity  if the  Corporation is not  continuing) would  be able to
Incur at least  $1.00 of additional  Indebtedness under the  first paragraph  of
"--  Limitation on  Indebtedness"; and (iv)  immediately after  giving effect to
such transaction or  series of  transactions on  a pro  forma basis  (including,
without  limitation, any Indebtedness Incurred or  anticipated to be Incurred in
connection  with  such  transaction  or  series  of  transactions)  as  if  such
transaction  had  occurred on  the first  day of  the Determination  Period, the
Corporation (or the surviving entity if the Corporation is not continuing) shall
have a Consolidated  Net Worth  equal to or  greater than  the Consolidated  Net
Worth  of  the Corporation  immediately prior  to the  transaction or  series of
transactions. The  foregoing  restriction  will  not  apply  to  the  merger  or
consolidation  of a  Restricted Subsidiary of  the Corporation with  or into the
Corporation. In the event  the Corporation reaches  Investment Grade Status  and
notwithstanding that the Corporation's Debt Rating thereafter ceases to be rated
Investment  Grade by either S&P or Moody's or both the restrictions contained in
clauses (iii) and  (iv) above shall  cease to  apply. Because the  term "all  or
substantially  all" may not  have an established  meaning and may  depend on the
facts and circumstances of
    

                                       47
<PAGE>
a particular transaction, including the qualitative as well as the  quantitative
aspects  of such  transaction, there  may be  an uncertainty  in the  ability of
holders  or  the  Indenture  Trustee  to  determine  when  a  sale  of  all   or
substantially  all of the assets has occurred and thus an uncertainty of holders
or the Indenture Trustee to  determine as to whether  a breach of this  covenant
has occurred.

EVENTS OF DEFAULT

   
    The  following are Events of Default under the Indenture with respect to the
Notes: (i) default in the  payment of any principal or  premium, if any, on  the
Notes  when the  same becomes  due and payable  at maturity,  or upon repurchase
pursuant to a Prepayment Offer as described in "-- Certain Restrictive Covenants
- -- Limitation on Asset Sales" above or pursuant to a Change of Control or  other
Designated  Event as described in "-- Change of Control" above; (ii) default for
30 days in the  payment of any interest  on the Notes; or  (iii) default for  60
days after written notice thereof in the performance of any covenant (other than
those  covered by  clauses (i)  and (ii)  of this  paragraph) applicable  to the
Notes; (iv) acceleration of maturity of  any Indebtedness of the Corporation  or
any  subsidiary in excess  of $50 million  principal amount in  the aggregate if
such acceleration results from  a default under the  instruments giving rise  to
such  indebtedness and is  not annulled within  10 days after  written notice of
such default; (v) the entry by a court of competent jurisdiction of one or  more
judgments   or  orders  against  the  Corporation   or  any  of  its  Restricted
Subsidiaries in an uninsured aggregate amount in excess of $50 million and  such
judgment or order is not discharged, waived, stayed or satisfied for a period of
45  consecutive  days;  or  (vi) certain  events  of  bankruptcy,  insolvency or
reorganization. In case  an Event  of Default (other  than an  Event of  Default
under  clause (vi)) shall occur and be continuing with respect to the Notes, the
Indenture Trustee or  the holders of  not less than  25% in aggregate  principal
amount  of the Notes then  outstanding by notice to  the Corporation may declare
the principal of the Notes to be due and payable immediately and if an Event  of
Default  under clause (vi) shall  occur and be continuing,  all such Notes shall
become due and  payable immediately without  any further action  or notice.  Any
Event  of Default with respect to the Notes  may be waived, and a declaration of
acceleration rescinded,  by the  holders of  a majority  in aggregate  principal
amount  of the Notes except in a case of failure to pay principal or premium, if
any, or interest in respect of the  Notes or failure to honor change of  control
provisions.  The  Indenture provides  that  the Indenture  Trustee  may withhold
notice to the security holders of  any default (except in payment of  principal,
premium,  if any, or interest) if it determines  in good faith that it is in the
interest of the security holders to do so. No Event of Default with respect to a
particular  series  of  securities   issued  under  the  Indenture   necessarily
constitutes  an Event of Default with respect  to any other series of securities
issued thereunder.
    

    Subject to the  provisions of the  Indenture relating to  the duties of  the
Indenture  Trustee in  case an  Event of Default  occurs and  is continuing, the
Indenture Trustee will be under no obligation  to exercise any of its rights  or
powers  under the Indenture,  at the request,  order or direction  of any of the
security holders, unless  such security  holders have offered  to the  Indenture
Trustee reasonable indemnity. Subject to such provisions for the indemnification
of  the Indenture  Trustee and  to certain other  limitations, the  holders of a
majority in aggregate principal amount of the securities of all series  affected
(voting as one class) at the time outstanding have the right to direct the time,
method  and place of conducting  any proceeding for any  remedy available to the
Indenture Trustee, or exercising any trust  or power conferred on the  Indenture
Trustee.

    The  Corporation is required to file  with the Indenture Trustee annually an
officers' certificate as to the absence  of certain defaults under the terms  of
the Indenture.

DEFEASANCE

    The  Corporation, at  its option,  (i) will be  discharged from  any and all
obligations in respect of the Notes (except for certain obligations to  register
the  transfer  or exchange  of  the Notes,  replace  stolen, lost,  destroyed or
mutilated certificates for the Notes,  maintain paying agencies and hold  moneys
for  payment in trust) or  (ii) will not be under  any obligation to comply with
certain covenants  and  provisions  applicable to  the  Notes,  including  those
described  above if the Corporation (A)  irrevocably deposits with the Indenture
Trustee, in trust for  the holders of  the Notes, (1)  money or (2)  noncallable
obligations issued or fully

                                       48
<PAGE>
guaranteed by the United States of America which through the payment of interest
and  income thereon and principal thereof will provide money, in each case in an
amount sufficient to  pay all  the principal  of (and  premium of,  if any)  and
interest  on the Notes on the dates such payments are due in accordance with the
terms of the Notes and (B) shall have  paid or caused to be paid all other  sums
payable  with respect to the Notes. To  exercise either of the options described
above, the  Corporation is  required,  among other  things,  to deliver  to  the
Indenture  Trustee an opinion of nationally recognized tax counsel to the effect
that holders of the Notes  will not recognize income,  gain or loss for  federal
income  tax  purposes as  a result  of such  deposit and  discharge and  will be
subject to federal income tax in the same  amount and in the same manner and  at
the same times as would have been the case if such deposit and discharge had not
occurred, and an officer's certificate and opinion of counsel to the effect that
all  conditions  precedent  relating to  such  deposit and  discharge  under the
Indenture have been complied with, and that such deposit and discharge will  not
cause  any violation of the  Investment Company Act of  1940, as amended, on the
part of the Corporation, the trust, the trust funds representing such deposit or
the Indenture Trustee.

MODIFICATION OF THE INDENTURE

    The  Indenture  contains  provisions  permitting  the  Corporation  and  the
Indenture   Trustee  to  modify  or  otherwise   amend  the  Indenture,  or  any
supplemental indenture thereto or  the rights of the  holders of the  securities
issued  thereunder, with the consent of the  holders of not less than a majority
in principal amount  of the  securities of all  series at  the time  outstanding
under the Indenture which are affected by such modification or amendment (voting
as  one class); provided that no such modification or amendment shall (i) change
the fixed maturity of any securities, or reduce the principal amount thereof, or
premium, if any, or reduce  the rate or extend the  time of payment of  interest
thereon,  or reduce  the amount  due and  payable upon  the acceleration  of the
maturity thereof or the amount provable in bankruptcy, or make the principal of,
or interest or premium on,  any security payable in  any coin or currency  other
than that provided in such security; (ii) impair the right to institute suit for
the  enforcement of any  such payment on  or after the  stated maturity thereof;
(iii) reduce the  aforesaid percentage  in principal amount  of securities,  the
consent  of  the holders  of  which is  required  for any  such  modification or
amendment, or the percentage  required for the consent  of the holders to  waive
defaults,  without the consent  of the holder  of each security  so affected; or
(iv) modify or eliminate any  of the provisions of  the Indenture relating to  a
Change  of Control  or the  obligation of the  Corporation to  offer to purchase
Notes as set forth in "--  Certain Restrictive Covenants -- Limitation on  Asset
Sales,"  without, in the case of this clause (iv), the consent of holders of not
less than two-thirds in principal amount of securities so affected.

other Property  being  sold, leased,  or  otherwise  disposed of,  in  a  single
transaction  or series of transactions, exceeds  $25 million (except in the case
of issuances of capital stock described in clause (x) above, as to which the $25

    "Attributable Value"  means, as  to  any particular  lease under  which  any
Person  is at the time liable, other than a Capital Lease Obligation, and at any

amount of rent required to  be paid by such Person  under such lease during  the
initial  term thereof as determined in accordance with GAAP, discounted from the

amount of rent  required to be  paid under any  such lease for  any such  period
shall be the aggregate amount of rent payable by the lessee with respect to such
period  after excluding  amounts required  to be  paid on  account of insurance,
taxes, assessments, utility, operating and  labor costs and similar charges.  In
the  case of any lease which  is terminable by the lessee  upon the payment of a
penalty, such net amount shall also include  the amount of such penalty, but  no
rent  shall be considered as required to  be paid under such lease subsequent to
the first date upon which it may be so terminated.

    "Average Life" means, as of any date,  with respect to any debt security  or
Redeemable  Stock that is Preferred Stock, the quotient obtained by dividing (i)
the sum of the products of (x) the number of years from such date to the date of

<PAGE>
Person  which is required to be classified  and accounted for as a capital lease
or a liability on the face of a balance sheet of such Person in accordance  with
GAAP.  The amount of any such Capital  Lease Obligation shall be the capitalized

in the Corporation's financial statements most recently filed under the Exchange
Act.

    "Capital  Stock"  in  any  Person  means  any  and  all  shares,  interests,
participations  or other equivalents in the equity interest (however designated)
in such Person and  any rights (other than  debt securities convertible into  an
equity  interest), warrants or options to subscribe  for or to acquire an equity
interest in such Person.

    "Change of Control" means an event or  series of events by which (i)(A)  the
Corporation  consolidates  with  or merges  into  any other  Person  or conveys,
transfers or leases  all or substantially  all of  its assets to  any Person  or
group  of  Persons  or (B)  any  Person  consolidates with  or  merges  into the
Corporation, in the  case of  either (A)  or (B)  pursuant to  a transaction  or
series  of  transactions (other  than a  transaction  or series  of transactions
between the  Corporation  and  a  wholly  owned  Restricted  Subsidiary  of  the
Corporation  if permitted under  "Restrictions on Merger") as  a result of which
the existing shareholders  of the  Corporation immediately  prior thereto  would
hold  less than  50% of  the combined voting  power of  the Voting  Stock of the
surviving Person, or (ii)  any "person" or "group"  (each as defined in  Section
13(d)(3)  and  13d-5 of  the Exchange  Act) becomes  the "beneficial  owner" (as

Moody's)  shall be taken into  account (e.g., with respect  to S&P, a decline in

Senior  2017 Debentures  were issued under  the Indenture  (the "Other Indenture
Securities"). The  Senior 1996  Notes bear  interest at  8% per  annum and  will

and will mature on March 15, 1997. The Senior 2001 Notes bear interest at 9 1/4%
per annum and will mature on September 15, 2001. The Senior 2017 Debentures bear
interest  at  8 3/4%  per annum  and will  mature  on March  1, 2017.  The Other
Indenture Securities rank pari  passu with the Notes  and with all other  senior
indebtedness  of the Corporation. The Other Indenture Securities will be secured
by  security  interests  in  capital  stock  of  certain  of  the  Corporation's
subsidiaries  under  the Collateral  Trust  Agreement. See  "Capitalization" and
"Description of Collateral Trust."
    

    The Senior 1996 Notes, the Senior 1997  Notes and the Senior 2001 Notes  may
not be redeemed at the option of the Corporation prior to maturity.

    The  Senior 2017 Debentures may be redeemed at the option of the Corporation
at face amount plus a premium in whole or in part from time to time on at  least
30 and not more than 90 days' notice by mail to registered holders thereof.

    Notwithstanding  the foregoing provision, the Corporation may not redeem any

from  or  in  anticipation of  moneys  borrowed by  or  for the  account  of the
Corporation or any of its  Subsidiaries at an interest  cost of less than  8.77%
per annum.

    As  a mandatory sinking fund for the Senior 2017 Debentures, the Corporation
will pay to the Indenture Trustee before March  1, in each of the years 1998  to
2016,  inclusive, an amount  in cash sufficient  to redeem, at  the Sinking Fund
Redemption Price,  $10,000,000 aggregate  principal amount  of the  Senior  2017
Debentures.  At its  option, the  Corporation may  pay to  the Indenture Trustee
before each mandatory  sinking fund payment  date an additional  amount in  cash
sufficient  to redeem at the  Sinking Fund Redemption Price  up to an additional
$15,000,000 aggregate principal amount of the Senior 2017 Debentures. The  right
to  make such optional sinking fund payments is not cumulative, but any optional
sinking fund  payment  may  be used  to  reduce  the amount  of  any  subsequent
mandatory sinking fund payment.

    The  Other Indenture  Securities are  entitled to  the benefit  of covenants
limiting the ability of the  Corporation and certain restricted subsidiaries  to
(i)  incur certain secured  debt without equally and  ratably securing the Other
Indenture Securities, (ii) entering into certain sale and leaseback transactions
involving  principal   operating  properties   and  (iii)   enter  into   merger
transactions  unless certain conditions are  satisfied. The provisions described
above under "Description of Notes" concerning defeasance also apply to the Other
Indenture Securities.

    The Corporation and U.S. Gypsum are  co-obligors with respect to the 7  7/8%
Sinking Fund Debentures due 2004 (the "Senior 2004 Debentures"). The Senior 2004
Debentures  will  also be  secured  by security  interests  in capital  stock of
certain of the  Corporation's domestic subsidiaries  under the Collateral  Trust
Agreement. See "Capitalization" and "Description of Collateral Trust."

<PAGE>
                        DESCRIPTION OF COLLATERAL TRUST

   
    In  connection with entering into the  New Credit Agreement, the Corporation
established a collateral trust pursuant  to the Collateral Trust Agreement  (the
"Collateral  Trust  Agreement"),  among  the  Corporation  and  its  significant
subsidiaries (collectively,  the "Grantors")  and Wilmington  Trust Company  and
William  J. Wade (collectively, the  "Collateral Trustee"). Under the Collateral
Trust Agreement, the Grantors granted a security interest in all of the  capital
stock  (and  associated  rights  and  proceeds  thereof)  of  the  Corporation's
significant subsidiaries which  presently include U.  S. Gypsum, USG  Interiors,
L&W  Supply and USG Foreign  Investments, Ltd. (collectively, the "Collateral").
The Collateral will be held  in trust for the equal  and ratable benefit of  the
holders  of  (i)  the Bank  Debt,  (ii)  the Notes,  (iii)  the  Other Indenture
Securities, (iv) the Senior 2004 Debentures,  (v) the 10 1/4% Senior Notes,  and
(vi)  any indebtedness  that arises from  the refinancing of  the foregoing (the
"Senior Secured Obligations").
    

    Under the Collateral  Trust Agreement, an  "Actionable Default" occurs  upon
the  acceleration  of  any  of  the Senior  Secured  Obligations.  A  "Notice of
Actionable Default" may be  given (i) in  the case of  acceleration of the  Bank
Debt,  automatically  or by  the agent  under  the New  Credit Agreement  at the
request or with the consent of the holders  of a majority of the Bank Debt  (the
"Requisite  Bank Lenders"); or (ii) in the case of an acceleration of any series
of  securities  or  other  refinancing  instrument  by  the  trustee  or   other
representative  under the  indenture or  refinancing instrument  or, if provided
under the terms of  such indenture or refinancing  instrument, by the  requisite
holders  of such debt.  A Notice of  Actionable Default may  be withdrawn by the
party which gave it (i) at any time before the Collateral Trustee has  exercised
any  remedies with respect to  the Collateral as a  result thereof or (ii) after
the Collateral Trustee has exercised remedies if (a) the Corporation indemnifies
the holders of  the Senior  Secured Obligations with  respect to  the costs  and
expenses  incurred by  them in  connection with  reversing all  actions that the
Collateral Trustee has taken to exercise any remedy or remedies with respect  to
the Collateral and (b) the Requisite Bank Lenders consent to such withdrawal. In
addition,  a Notice  of Actionable  Default is  deemed withdrawn  when the party
giving such  Notice has  acknowledged  payment in  full  of the  Senior  Secured
Obligations  owing to it. Until such time as any Notice of Actionable Default is
given (and after the time when any such Notice has been withdrawn), the  pledgor
thereof may vote any securities comprising Collateral. At any time when a Notice
of  Actionable Default has been given  and not withdrawn, the Collateral Trustee
may, upon  written notice  to the  Corporation, vote  any securities  comprising
Collateral.

    All  of the  Collateral will be  released (i) once  the Corporation's senior
public debt is rated "Investment Grade" (a rating of BBB- or higher by  Standard
&  Poor's Ratings Group and  Baa3 or higher by  Moody's Investors Service, Inc.)
and all accrued  and unpaid Collateral  Trustee's fees have  been paid in  full,
(ii)  upon the consent and direction of all holders of Bank Debt and all accrued
and unpaid Collateral Trustee's fees  have been paid in  full, or (iii) at  such
time  as the Bank Debt has  been repaid in full and  the commitments of the Bank
Group to made advances  under the New Credit  Agreement have terminated and  all
accrued  and  unpaid  Collateral  Trustee's  fees have  been  paid  in  full. In
addition, the  Requisite Bank  Lenders may  instruct the  Collateral Trustee  to
release  specified portions of the Collateral (e.g.,  in the case of asset sales
approved by  the  holders of  the  Bank Debt  under  the New  Credit  Agreement)
provided  that no Actionable Default  has occurred. The holders  of the Notes do
not have any similar  rights to authorize release  of the Collateral. Under  the
terms  of the Collateral  Trust Agreement, the Collateral  so released revert to
the Grantors and are not required to be distributed into the Collateral  Account
(defined below). For a description of the rights of the holders of the Bank Debt
under the New Credit Agreement, see "Description of New Credit Agreement."

    Following  receipt of a Notice of Actionable Default and during such time as
such Notice of Actionable Default shall  not have been withdrawn, the  Requisite
Bank  Lenders have the  right to direct  the Collateral Trustee  to exercise, or
refrain from exercising, any rights or remedies with respect to the  Collateral.
The  holders of the Notes do not have any similar right to direct the actions of
the Collateral  Trustee.  See  "Risk  Factors  -  Control  of  Collateral  Trust
Agreement  by Bank Group." At  any time when a  Notice of Actionable Default has
been given and not withdrawn, the  Collateral Trustee may, and at the  direction
of the Requisite Bank Lenders shall, among other things, sell the Collateral for
the benefit of the holders of the Senior Secured Obligations. Funds derived from
any  sale of Collateral and  (at all times after  a Notice of Actionable Default
has been given and  not withdrawn) dividends and  distributions received on  the
Collateral are to be

                                       60
<PAGE>
deposited  to  the collateral  account  established under  the  Collateral Trust
Agreement (the "Collateral  Account"). The Collateral  Trustee shall  distribute
all  moneys in the Collateral  Account as follows: (i)  first, to the Collateral
Trustee for  unpaid fees;  (ii) second,  to the  holders of  the Senior  Secured
Obligations  ratably (on the basis of unpaid  amounts) to (a) pay the portion of
the Senior Secured  Obligations which is  then due and  payable and (b)  provide
cash  collateral (on  a dollar-for-dollar basis)  for the portion  of the Senior
Secured Obligations which is not then due  and payable; and (iii) third, to  the
Grantors.

    In the Underwriting Agreement, the several Underwriters have agreed, subject
to  the terms and conditions set forth therein, to purchase the entire amount of
the Notes  offered hereby  if any  Notes are  purchased. The  Underwriters  have
advised  the Corporation that they  propose initially to offer  the Notes to the
public at  the  public offering  price  set forth  on  the cover  page  of  this
Prospectus  and to certain dealers at such  offering price less a concession not
in excess of 0.50 percent of the principal amount of the Notes. The Underwriters
may allow, and  such dealers may  reallow, a  concession not in  excess of  0.25
percent of the principal amount of the Notes to certain other dealers. After the
offering  of the Notes commences, the  public offering price or such concessions
may be  changed.  In  the  event  of  a default  by  any  one  or  more  of  the
Underwriters,   the   Underwriting   Agreement   provides   that,   in   certain
circumstances, the purchase commitment of the nondefaulting Underwriters may  be
increased or the Underwriting Agreement terminated.
    

    The  Underwriting Agreement provides that the Corporation will indemnify the
Underwriters  against  certain  liabilities,  including  liabilities  under  the
Securities  Act  of 1933,  or  contribute to  payments  the Underwriters  may be
required to make in respect thereof.

    The Underwriters have advised the Corporation that they currently intend  to
make  a market in  the Notes; however, they  are not obligated to  do so and any
market making may be discontinued at  any time without notice. No assurance  can
be  given as to the development or liquidity of any trading market in the Notes.
If an active  market does not  develop, the  market price and  liquidity of  the
Notes may be adversely effected.

    The Underwriters and their affiliates from time to time engage in investment
banking and commercial banking transactions with the Corporation in the ordinary
course  of business. Chemical Securities  Inc. is acting as  arranger of the New
Credit Agreement, and its affiliate, Chemical Bank, is agent bank under the  New

                   INDEX TO CONSOLIDATED FINANCIAL STATEMENTS

    On  May  6,  1993,  the  Corporation  completed  the  Restructuring  through
implementation of the Prepackaged  Plan as described in  the notes to  financial
statements.  The  consolidated financial  statements and  notes thereto  for the
interim periods ended March  31, 1995 and 1994,  presented on pages F-2  through
F-12,  and the year ended December 31, 1994 and period of May 7 through December
31, 1993, presented on  pages F-13 through F-44,  report financial data for  the
restructured   USG   Corporation.  As   a  result   of  the   Restructuring  and
implementation of fresh start  accounting, these restructured company  financial
results  are not comparable to  results reported in the  periods prior to May 7,
1993 for the predecessor USG Corporation which are presented separately for  the
period  of January 1 through May 6, 1993 and the year ended December 31, 1992 on
pages F-47 through  F-73. Because the  Restructuring was implemented  on May  6,
1993,  the Restructuring transaction and  accounting adjustments associated with
the implementation of fresh start accounting are reflected in the results of the
predecessor company. All historical financial information presented on pages F-2
through F-77 should be read in conjunction with the information included in this
Prospectus under "Capitalization," and "Management's Discussion and Analysis  of
"Results of Operations and Financial Condition."

                                USG CORPORATION
                             (RESTRUCTURED COMPANY)
                     NOTES TO INTERIM FINANCIAL STATEMENTS
                                  (UNAUDITED)

 (1) The   consolidated  financial   statements  of  USG   Corporation  and  its
     subsidiaries  ("USG"  or  the  "Corporation")  included  herein  have  been
     prepared  pursuant  to  the rules  and  regulations of  the  Securities and
     Exchange Commission. In the opinion  of management, the statements  reflect
     all  adjustments,  which are  of a  normal  recurring nature,  necessary to
     present fairly the Corporation's  financial position as  of March 31,  1995
     and  December 31, 1994;  and results of  operations and cash  flows for the
     three months ended March 31, 1995  and 1994. While these interim  financial
     statements and accompanying notes are unaudited, they have been reviewed by
     Arthur  Andersen  LLP,  the Corporation's  independent  public accountants.
     These financial statements and notes are to be read in conjunction with the
     financial statements and  notes included in  the Corporation's 1994  Annual
     Report on Form 10-K dated March 8, 1995.

 (2) In  the fourth  quarter of  1994, the  Corporation established  a revolving
     accounts receivable facility. Under this  new financing program, the  trade
     receivables  of  United  States  Gypsum  Company  ("U.S.  Gypsum")  and USG
     Interiors, Inc.  ("USG  Interiors")  are being  purchased  by  USG  Funding
     Corporation  ("USG  Funding") and  transferred to  a trust  administered by
     Chemical Bank as trustee.  Certificates representing an ownership  interest
     of  up to  $130 million in  the trust have  been issued to  an affiliate of
     Citicorp North America, Inc. USG  Funding, a special purpose subsidiary  of
     USG  Corporation,  is a  separate corporate  entity  with its  own separate
     creditors which  will be  entitled to  be satisfied  out of  USG  Funding's
     assets  prior  to  any  value  in USG  Funding  becoming  available  to its
     shareholder. Receivables  and  debt  outstanding  in  connection  with  the
     receivables   facility   remain   in   receivables   and   long-term  debt,
     respectively, on the Corporation's consolidated balance sheet.

 (3) On May 6, 1993, the Corporation completed a comprehensive restructuring  of
     its  debt through implementation of  a "prepackaged" plan of reorganization
     under United  States  bankruptcy law.  The  Corporation accounted  for  the
     restructuring using the principles of fresh start accounting as required by
     AICPA  Statement  of Position  90-7,  "Financial Reporting  by  Entities in
     Reorganization under the Bankruptcy Code"  ("SOP 90-7" ). Pursuant to  such
     principles,  individual assets and liabilities were adjusted to fair market
     value. Excess reorganization value, the portion of the reorganization value
     not attributable to specific  assets, is being  amortized over a  five-year
     period, effective May 7, 1993.

 (4) Income  tax expense amounted to  $27 million and $10  million for the three
     months ended  March  31, 1995  and  1994, respectively.  The  Corporation's
     income  tax expense  is computed  based on  pre-tax earnings  excluding the
     non-cash  amortization  of  excess  reorganization  value,  which  is   not
     deductible  for federal income tax  purposes. Further, under the provisions
     of SOP 90-7, the benefits of the domestic net operating loss  carryforwards
     ("NOL  Carryforwards")  discussed below  are  not reflected  in  income tax
     expense.

    The Corporation has NOL  Carryforwards of $49  million remaining from  1992.
    These  NOL Carryforwards may  be used to offset  U.S. taxable income through
    2007. The Internal Revenue Code limits  the Corporation's annual use of  its
    NOL  Carryforwards to the lesser of  its taxable income or approximately $30
    million plus any  unused limit  from prior  years. Furthermore,  due to  the
    uncertainty  regarding the application  of the Internal  Revenue Code to the
    exchange of stock for debt, the Corporation's NOL Carryforwards to 1994  and
    later years could be reduced or eliminated. The Corporation has a $4 million
    minimum tax credit which may be used to offset U.S. regular tax liability in
    future years.

 (5) As  of March  31, 1995,  2,750,555 common  shares were  reserved for future
     issuance in conjunction  with existing stock  option grants. An  additional
     11,105 common shares were reserved for future grants.

 (6) One  of  the  Corporation's  operating  subsidiaries,  U.S.  Gypsum,  is  a
     defendant in asbestos lawsuits alleging  both property damage and  personal
     injury.   Virtually   all  costs   of   the  Personal   Injury   Cases  are

                                USG CORPORATION
                             (RESTRUCTURED COMPANY)
               NOTES TO INTERIM FINANCIAL STATEMENTS (CONTINUED)
                                  (UNAUDITED)
    being paid by insurance. However,  many of U.S. Gypsum's insurance  carriers
     are  denying coverage for  the Property Damage  Cases, although U.S. Gypsum
     believes that  substantial  coverage exists  and  the trial  court  and  an
     appellate  court  in  U.S.  Gypsum's Coverage  Action  have  so  ruled. The
     carriers are  seeking  reconsideration  of  the  Illinois  Supreme  Court's
     refusal  to review  the appellate  court's ruling.  In view  of the limited
     insurance funding currently  available to U.S.  Gypsum for Property  Damage
     Cases  resulting from  continued resistance  by a  number of  U.S. Gypsum's
     insurers to providing coverage,  the effect of  the asbestos litigation  on
     the  Corporation  will  depend upon  a  variety of  factors,  including the
     damages sought  in Property  Damage Cases  that reach  trial prior  to  the
     completion  of the Coverage  Action, U.S. Gypsum's  ability to successfully
     defend or settle such cases, and the resolution of the Coverage Action.  As
     a  result, management is unable to  determine whether an adverse outcome in
     the asbestos litigation will have a material adverse effect on the  results
     of operations or the consolidated financial position of the Corporation.

    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.

 (7) On January 1, 1985, all  of the issued and  outstanding shares of stock  of
     U.S.  Gypsum were converted into shares  of USG Corporation and the holding
     company  became  a  joint  and  several  obligor  for  certain   debentures
     originally  issued by U.S. Gypsum. Debentures  totaling $22 million and $33
     million were recorded on the holding company's books of account as of March
     31, 1995 and December 31, 1994, respectively. Summary financial results for
     U.S. Gypsum are presented below (dollars in millions):

 (8) As of March 31,  1995, $298 million aggregate  principal amount of 10  1/4%
     senior   notes  due  2002  were  outstanding.  Each  of  U.S.  Gypsum,  USG
     Industries, Inc., USG Interiors, USG Foreign Investments, Ltd., L&W  Supply
     Corporation,  Westbank Planting Company, USG Interiors International, Inc.,
     American Metals Corporation and La Mirada Products Co., Inc. (together, the
     "Combined Guarantors")  guaranteed,  in  the manner  described  below,  the
     obligations  of the Corporation under its bank term loans' credit agreement
     and 10 1/4% senior notes. The Combined Guarantors are jointly and severally
     liable under the guarantees. Holders of the bank term loans have the  right
     to:  (i) determine whether, when and to  what extent the guarantees will be
     enforced (provided that each guarantee payment will be applied to the  bank
     term  loans  and 10  1/4% senior  notes  pro rata  based on  the respective
     amounts owed  thereon); and  (ii) amend  or eliminate  the guarantees.  The
     guarantees  will terminate when the bank  term loans are retired regardless
     of whether any such  10 1/4% senior notes  remain unpaid. The liability  of
     each  of the Combined Guarantors on its guarantee is limited to the greater
     of: (i)  95%  of  the  lowest  amount, calculated  as  of  July  13,  1988,
     sufficient  to  render the  guarantor insolvent,  leave the  guarantor with
     unreasonably small capital or leave the  guarantor unable to pay its  debts
     as  they become due  (each as defined  under applicable law);  and (ii) the
     same amount, calculated as  of the date any  demand for payment under  such
     guarantee  is made, in each case  plus collection costs. The guarantees are
     senior obligations of the applicable guarantor and rank PARI PASSU with all
     unsubordinated obligations of the guarantor.

    Subsidiaries   other   than   the   Combined   Guarantors   (the   "Combined
    Non-Guarantors"), substantially all of which are subsidiaries of Guarantors,
    primarily  include  CGC Inc.,  Gypsum  Transportation Limited,  USG Canadian

                         NOTES TO FINANCIAL STATEMENTS
  (TERMS IN INITIAL CAPITAL LETTERS ARE DEFINED ELSEWHERE IN THIS PROSPECTUS)

PRINCIPLES OF CONSOLIDATION

    The   consolidated  financial   statements  include  the   accounts  of  the
Corporation and its subsidiaries after elimination of intercompany accounts  and
transactions.  Revenue is recognized upon the shipment of products. Net currency
translation gains or  losses on  foreign subsidiaries are  included in  deferred
currency translation, a component of stockholders' equity.

    Excess  reorganization  value,  which  was  recorded  as  a  result  of  the
implementation of fresh start accounting, is being amortized through April 1998.
The Corporation  continues to  evaluate whether  events and  circumstances  have
occurred   that  indicate  the   remaining  estimated  useful   life  of  excess
reorganization value may warrant revision or that the remaining balances may not
be recoverable. The Corporation uses an estimate of its undiscounted cash  flows
over  the remaining life of the excess reorganization value in measuring whether
the asset  is recoverable.  See "Financial  Restructuring" note  below for  more
information on the implementation of fresh start accounting.

    For purposes of the Consolidated Balance Sheet and Consolidated Statement of
Cash  Flows, all highly  liquid investments with  a maturity of  three months or
less at the time of purchase are considered to be cash equivalents.

FINANCIAL RESTRUCTURING

    On May 6, 1993, the  Corporation completed a comprehensive restructuring  of
its debt (the "Restructuring") through implementation of a "prepackaged" plan of
reorganization  under United States bankruptcy  law (the "Prepackaged Plan"). In
accordance with the  terms of  the Prepackaged Plan,  $1.4 billion  of debt  and
accrued  interest was converted into  equity, interest expense was significantly
reduced and the maturities of a  substantial portion of its remaining debt  were
extended.  The Corporation accounted for  the Restructuring using the principles
of fresh  start accounting  as required  by AICPA  Statement of  Position  90-7,
"Financial  Reporting by Entities  in Reorganization under  the Bankruptcy Code"
("SOP 90-7"). Pursuant  to such  principles, individual  assets and  liabilities
were  adjusted to  fair market  value as of  May 6,  1993. Excess reorganization
value, the  portion of  the reorganization  value not  attributable to  specific
assets, is being amortized over a five-year period, effective May 7, 1993.

    The  following  unaudited  Pro  Forma  Condensed  Consolidated  Statement of
Earnings for the year ended December 31, 1993 has been prepared giving effect to
the consummation of  the Restructuring,  including the  implementation of  fresh
start accounting, as if the consummation had occurred on January 1, 1993. Due to
the  Restructuring  and  implementation  of  fresh  start  accounting, financial
statements effective May 7, 1993 for the Restructured Company are not comparable
to financial statements prior to that date for the Predecessor Company. However,
for presentation of this statement, total  results for 1993 are shown under  the
caption  "Total Before Adjustments." The adjustments set forth under the caption
"Pro Forma Adjustments" reflect the  implementation of the Prepackaged Plan  and
the  adoption of fresh  start accounting as  if they had  occurred on January 1,
1993.

ACCOUNTS RECEIVABLE FACILITY

    In  the fourth  quarter of  1994, the  Corporation entered  into an accounts
receivable facility (the "Receivables Facility") in which USG Funding, a special
purpose subsidiary of the Corporation,  formed under Delaware law, entered  into
agreements with U.S. Gypsum and USG Interiors. These agreements provide that USG
Funding will purchase 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 Chemical 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 $100 million  were issued to Citicorp  Securities,
Inc.  The interest  rate on  the debt issued  under the  Receivables Facility is
fixed at approximately 8.9% (including facility costs)

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
through a  long-term  interest rate  swap.  Under  a pending  amendment  to  the
Receivables Facility, debt issued under such facility will have a final maturity
in  2004 and the Corporation will have the  option to expand such facility up to
$130 million. Debt issued under the  Receivables Facility may be prepaid at  any
time.  Pursuant  to the  applicable  reserve and  eligibility  requirements, the
maximum amount of debt  issuable under the Receivables  Facility as of  December
31,  1994 (including the $80 million outstanding at such date) was $103 million.
Under the  foregoing agreements  and  related documentation,  USG Funding  is  a
separate corporate entity with its own separate creditors which 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, 1994, the outstanding balance of receivables sold to  USG
Funding  and held under the  Master Trust was $151  million and debt outstanding
under the Receivables Facility was $80 million. Receivables and debt outstanding
in connection with the Receivables Facility remain in receivables and  long-term
debt, respectively, on the Corporation's consolidated balance sheet.

EXTRAORDINARY LOSS

    In  December 1993,  the Corporation  recorded an  extraordinary loss  of $21
million, net  of related  income  tax benefit  of  $11 million,  reflecting  the
write-off  of the reorganization  discount associated with  debt issues prepaid,
redeemed or purchased in  1994 in connection with  the Equity Offering and  Note
Placement.   See  "Indebtedness"  and  "Stockholders'  Equity"  notes  for  more
information on the Equity Offering and Note Placement.

RESEARCH AND DEVELOPMENT

    Research and development  expenditures are charged  to earnings as  incurred
and  amounted to $17 million in the year ended December 31, 1994 and $10 million
in the period of May 7 through December 31, 1993.

    A valuation allowance has been provided for deferred tax assets relating  to
pension  and  retiree medical  benefits  due to  the  long-term nature  of their
realization. Because  of  the  uncertainty  regarding  the  application  of  the
Internal Revenue Code to the Corporation's net operating loss carryforwards (the
"NOL  Carryforwards") as a result of the Prepackaged Plan, no deferred tax asset
is recorded.  Under fresh  start  accounting rules,  any benefit  realized  from
utilizing predecessor company NOL Carryforwards will not impact net earnings.

    The  Corporation has  NOL Carryforwards of  $49 million  remaining from 1992
after using approximately  $50 million to  offset U.S. taxable  income in  1994.
These  NOL Carryforwards may be used to offset U.S. taxable income through 2007.
The Internal  Revenue  Code limits  the  Corporation's  annual use  of  its  NOL
Carryforwards  to the lesser of its  taxable income or approximately $30 million
plus any unused  limit from  prior years.  Furthermore, due  to the  uncertainty
regarding  the application of  the Code to  the exchange of  stock for debt, the
Corporation's NOL Carryforwards  to 1994  and later  years could  be reduced  or
eliminated.  The Corporation has  a $4 million  minimum tax credit  which may be
used to offset U.S. regular tax liability in future years.

    The Corporation  does not  provide  for U.S.  Federal  income taxes  on  the
portion  of undistributed earnings of foreign subsidiaries which are intended to
be permanently reinvested. The cumulative amount of such undistributed  earnings
totaled   approximately  $93  million  as  of  December  31,  1994.  Any  future
repatriation of undistributed earnings would not, in the opinion of  management,
result in significant additional taxes.

INVENTORIES

    Most of the Corporation's domestic inventories are valued under the last-in,
first-out  ("LIFO") method. In accordance with the implementation of fresh start
accounting, inventories were stated at fair market  value as of May 6, 1993.  As
of December 31, 1994, the LIFO values of these inventories were $121 million and
would  have  been $5  million higher  if  they were  valued under  the first-in,
first-out ("FIFO") and average production cost methods. As of December 31, 1993,
inventories valued under  the LIFO method  totaled $103 million  and would  have
been  the same if  they were valued  under the FIFO  and average production cost

PROPERTY, PLANT AND EQUIPMENT

    Property, plant and equipment were stated at fair market value as of May  6,
1993  in accordance with fresh start accounting. Provisions for depreciation 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. Interest during construction is  capitalized
on  major property additions. Property, plant and equipment classifications were

    As  of December  31, 1994, the  Corporation and its  subsidiaries had $1,149
million total  principal  amount  of  debt  (before  unamortized  reorganization
discount)  on a consolidated basis. Of such total debt, $159 million represented
direct borrowings by the subsidiaries, including $80 million borrowed under  the
Receivables  Facility, $39 million  of industrial revenue  bonds, $33 million of
7 7/8% sinking fund  debentures issued by U.S.  Gypsum in 1974 and  subsequently
assumed  by the Corporation on a joint and several basis in 1985, and $7 million
of debt incurred by the Corporation's foreign subsidiaries.

    The Bank Term Loans and  most other senior debt are  secured by a pledge  of
all  of the shares of  the Corporation's major domestic  subsidiaries and 65% of
the shares of certain of its foreign subsidiaries

including CGC, pursuant to a  collateral trust arrangement controlled  primarily
by  holders  of the  Bank  Term Loans.  The rights  of  the Corporation  and its
creditors to  the assets  of any  subsidiary upon  the latter's  liquidation  or
reorganization  will  be  subject  to  the  prior  claims  of  such subsidiary's
creditors, except to the  extent that the Corporation  may itself be a  creditor
with enforceable claims against such subsidiary.

    The fair market value of debt outstanding as of December 31, 1994 was $1,109
million,  based  on indicative  bond  prices as  of  that date,  excluding other
secured debt, which was  not practicable to estimate.  As of December 31,  1993,
the  fair market  value of  debt was  $1,481 million,  based on  indicative bond
prices as of  that date,  excluding other secured  debt, primarily  representing
financing  for construction of  the Aubange plant, which  was not practicable to
estimate.

    The "other  secured  debt"  category  shown in  the  table  above  primarily
includes  short-term and long-term borrowings from  several foreign banks. As of
December  31,  1993,  this  category   primarily  included  borrowings  by   USG
International  used principally to finance  construction of the Aubange, Belgium
ceiling tile plant. This debt, which was  repaid in 1994, was secured by a  lien
on  the  assets  of  the  Aubange  plant  and  had  restrictive  covenants  that
restricted, among other  things, the  payment of  dividends. Foreign  borrowings
made by the Corporation's international operations are generally allowed, within
certain limits, under provisions of the Credit Agreement.

    The  weighted average interest rate on outstanding short-term borrowings was
9.2% and 6.6% as of December 31, 1994 and 1993, respectively.

    As of December 31, 1994,  aggregate scheduled maturities of long-term  debt,
excluding  amounts  classified as  current  liabilities, were  $37  million, $45
million,  $4  million  and  $73  million  for  the  years  1996  through   1999,
respectively.

THE CREDIT AGREEMENT

    The  Bank Term Loans were issued in connection with the Credit Agreement. In
general, the Credit Agreement restricts,  among other things, the incurrence  of
additional indebtedness, mergers, asset dispositions, investments, prepayment of
other debt, dealings with affiliates, capital expenditures, payment of dividends
and  lease commitments and requires the  Corporation, beginning January 1, 1995,
to satisfy  certain financial  covenants. An  agreement with  Water Street  also
requires the Corporation to satisfy certain financial covenants.

    The average rate of interest on the Bank Term Loans was 6.2% and 5.3% in the
year  ended December 31, 1994 and the period of May 7 through December 31, 1993,
respectively.

    The  Credit  Agreement  provides  for  a  revolving  credit  facility   (the
"Revolving  Credit Facility").  As of  December 31,  1994, the  Revolving Credit
Facility amounted to  $245 million, including  a $115 million  letter of  credit
subfacility  and $70 million  available solely for the  purchase or repayment of
Senior 1996 Notes and Senior 1997 Notes. As of December 31, 1993, the  Revolving
Credit  Facility  amounted to  $175 million,  including the  aforementioned $115
million letter of credit subfacility.  Amounts committed and undrawn under  such
letter of credit subfacility were $58 million and $60 million as of December 31,
1994  and  1993,  respectively.  There were  no  amounts  outstanding  under the
Revolving Credit Facility as of December 31, 1994 and 1993.

    Under the Cash Sweep provision of the Credit Agreement, a portion of  excess
cash  as  of the  end  of any  year, calculated  in  accordance with  the Credit
Agreement, must be used  to pay Bank  Term Loans. As of  December 31, 1994,  the
Cash  Sweep amounted to $132 million, of  which 50%, or $66 million was required
to be used to pay  Bank Term Loans while the  remaining 50% was retained by  the
Corporation  for  general  corporate purposes.  The  portion of  the  Cash Sweep
required to  be used  to pay  Bank Term  Loans included  $25 million  which  was
prepaid  in the third quarter of 1994  and $41 million which was reclassified to

February  1995, the Corporation made a further  payment of $50 million to reduce
Bank Term Loans  outstanding. This additional  payment was applied  to the  1999
maturity  of the Bank  Term Loans thereby reducing  the 1999 aggregate scheduled
maturity shown above.

DEBT REFINANCING

    In the fourth quarter of 1994, the Corporation entered into the  Receivables
Facility.  As  of  December  31,  1994,  debt  issued  in  connection  with  the
Receivables Facility totaled  $80 million  and accounts receivable  held in  the
Master  Trust totaled $151 million. See  "Accounts Receivable Facility" note for
more information on the Receivables Facility.

    Also during the fourth  quarter of 1994, the  Corporation decided to  pursue
various refinancing alternatives related to its Bank Term Loans. The Corporation
intends to accelerate the payment of such loans in 1995 through a combination of
excess  cash flow and  proceeds from a  potential refinancing. As  a result, the
Corporation recorded  a  non-cash pre-tax  charge  of $16  million  to  interest
expense  reflecting  the  write-off of  reorganization  debt  discount primarily
associated with the Bank Term Loans.

    In the third quarter  of 1994, the Third  Amendment to the Credit  Agreement
was  consummated. In  connection with such  amendment, the  Corporation made the
aforementioned $25 million prepayment of the Cash Sweep. Major revisions to  the
Credit  Agreement provided by  the Third Amendment  included modification of the
Cash Sweep provision,  authorization for the  Corporation to immediately  prepay
certain  debt,  authorization  for the  Corporation  to enter  into  a revolving
accounts receivable  sale facility  and certain  other changes  to increase  the
Corporation's operating flexibility.

    In the first quarter of 1994, the Corporation implemented a refinancing plan
which  included (i) a public offering of  14,375,000 shares of common stock (the
"Equity Offering"),  of which  7,900,000 shares,  yielding net  proceeds to  the
Corporation  of $224 million, were newly issued by the Corporation and 6,475,000
were sold by Water  Street Corporate Recovery Fund  I, L.P. ("Water Street"),  a
stockholder;  (ii) the issuance of $150 million  of Senior 2001 Notes to certain
institutional investors  (the  "Note Placement")  in  exchange for  $30  million
aggregate  principal amount  of its outstanding  Senior 1996  Notes, $35 million
aggregate principal amount of its outstanding Senior 1997 Notes and $85  million
in  cash; and (iii) amendment of the  Credit Agreement for the second time since
the Restructuring. This amendment,  (together with the  Equity Offering and  the
Note  Placement,  the "Transactions")  increased the  size of  the Corporation's
revolving credit facility by $70 million  (solely for the purchase or  repayment
of Senior 1996 Notes and Senior 1997 Notes) and amended the Cash Sweep provision
to  allow the Corporation,  upon the achievement of  certain financial tests, to
retain additional free cash flow for  capital expenditures and repayment of  its
public debt.

    In August, 1993, the Corporation issued $138 million of Senior 2002 Notes in
exchange  for Bank Term Loans  and other debt then  outstanding under the Credit
Agreement. The Corporation did not receive  any cash proceeds from the  issuance
of  these securities. In  connection with this transaction,  an amendment to the
Credit Agreement  provided for  the  elimination of  scheduled Bank  Term  Loans
payments  through 1996, prepayment of $9 million of other debt outstanding under
the Credit Agreement and modification of the Cash Sweep provision.

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

differences between actual and estimated experience.

    The expected long-term rate  of return on  plan assets was  9% for the  year
ended  December 31, 1994 and the period of  May 7 through December 31, 1993. The
assumed weighted  average  discount rate  used  in determining  the  accumulated
benefit obligation was 8.25% and 7% as December 31, 1994 and 1993, respectively.
The  rate of increases in  projected future compensation levels  was 5% for both
periods.

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.

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 $20 million and $22 million as of December
31, 1994 and 1993,  respectively, and increase  the net periodic  postretirement
benefit  cost by $3 million and $2 million  for the year ended December 31, 1994

COMMITMENTS AND CONTINGENCIES

    The  Corporation   has  limited   involvement  with   derivative   financial
instruments  and does not use them for trading purposes. They are used primarily
to manage well-defined interest rate and energy cost risks as well as occasional
foreign currency exchange  exposure. The following  table presents the  carrying
amounts and estimated fair value of the Corporation's derivative portfolio as of
December 31, 1994 (dollars in millions):

                             (RESTRUCTURED COMPANY)
                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

    As of  December 31,  1993, the  Corporation had  approximately $455  million
notional  amount of interest  rate contracts outstanding,  extending up to three
years, and approximately $42  million notional amount  and $11 million  notional
amount  of  energy price  and foreign  currency exchange  contracts outstanding,
respectively, extending one year or less. The difference in the value of all  of
the  aforementioned contracts  and the  December 31,  1993 market  value was not
material.

    The Corporation is exposed to credit  losses in the event of  nonperformance
by  the counterparties  on all its  derivative contracts but  has no off-balance
sheet credit risk of accounting  loss. All counterparties have investment  grade
credit   standing  and  accordingly,  the  Corporation  anticipates  that  these
counterparties will  be  able  to  fully  satisfy  their  obligation  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

    The  Corporation purchased  prepaid interest rate  caps and  swap options to
manage the  impact of  interest rate  changes on  LIBOR-based bank  debt. As  of
December  31,  1994,  such instruments  owned  by the  Corporation  totaled $445
million, which capped the Corporation's expected LIBOR-based bank debt  payments
at  5.2% for  1995 ($250  million notional  amount), 7%  for 1996  ($120 million
notional amount) and 7% for 1997 ($75 million notional amount). In addition,  as
of  December 31, 1994, the Corporation had entered into $100 million of interest
rate swap and collar agreements to  hedge its Receivables Facility, under  which
$80  million was  outstanding as  of December  31, 1994.  In January  1995, such
interest rate swap  and collar agreements  were terminated at  par and  replaced
with  $80 million of new interest rate  swap agreements. Under the interest rate
swap agreements,  the  Corporation  pays  a fixed  rate  of  approximately  8.9%
(including  facility costs) in  exchange for the  monthly commercial paper-based
payments due on the Receivables Facility until its final maturity.

    Premiums paid for purchased  interest rate cap  agreements are amortized  to
interest expense over the term of the caps. Unamortized premiums are included in
other  assets on  the consolidated balance  sheet. Amounts  receivable under cap
agreements and receivables or payables under  swap agreements are accrued as  an
increase or decrease to interest expense as appropriate.

ENERGY COST RISK MANAGEMENT

    The  Corporation  uses energy  price  swap agreements  to  hedge anticipated
purchases of  fuel  to be  utilized  in  the manufacturing  process  for  gypsum
wallboard.  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. As of December 31,
1994, the Corporation had over-the-counter  swap agreements to exchange  monthly
payments  on notional amounts of energy  amounting to $23 million, all extending
one year or less.

    Upon settlement of  energy price contracts,  the resulting gain  or loss  is
included in cost of products sold, along with the actual spot energy cost of the
corresponding underlying hedged transaction, the combination of which amounts to
the predetermined specified contract price.

FOREIGN EXCHANGE RISK MANAGEMENT

    The  Corporation had no  foreign currency exchange  contracts as of December
31, 1994.

MANAGEMENT PERFORMANCE PLAN

    On May  6,  1993,  all  outstanding stock  options  were  cancelled  without
consideration  and all shares  of restricted and  deferred stock were cashed-out
pursuant  to  "change  in  control"  provisions  contained  in  the   Management
Performance  Plan except  for 25,580 shares  of restricted stock  and awards for
deferred stock yet to be issued  which remained outstanding as a consequence  of
certain waivers of the change in control

event  by senior members of management.  Those shares which remained outstanding
on May 6,  1993 were freed  of restrictions  in 1994, an  acceleration from  the
original  terms  which freed  the restrictions  on  incremental portions  of the
shares through 1998.

    As permitted by the Prepackaged Plan, a certain number of common shares were
reserved for future  issuance in  conjunction with stock  options. Options  were
granted  in 1993 and 1994 at an exercise price equal to the mean of the high and
low sales prices  for a  share of the  Corporation's common  stock (the  "Common
Stock") as reported on the NYSE composite tape on the grant dates. These options
become  exercisable at the rate  of one-third of the  aggregate grant on each of
the first three anniversaries of the date  of the grant and expire on the  tenth
anniversary  of the  date of 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. Stock option activity
for the year ended December  31, 1994 and the period  of May 7 through  December
31, 1993 was as follows:

PREFERRED SHARE PURCHASE RIGHTS

    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
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 which the Corporation's Board of Directors determines to represent a
threat   of  acquisition  not  in  the   best  interests  of  the  Corporation's
stockholders). 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  $35.00  per
one-hundredth  of  a preferred  share, subject  to  adjustment. The  Rights also
provide for  a so-called  "flip-in"  feature and  exchange feature  and  certain
exemptions  permitting certain acquisitions and  the continued holding of common
shares by Water Street and its  affiliates in excess of the otherwise  specified
thresholds.

    In  the  event that  the Corporation  is the  surviving corporation  and the
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, 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.

WARRANTS

    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  (the "Warrants"),  in
addition to Common Stock, were issued to holders of

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
certain  debt which was converted to equity in the Restructuring. 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.

    The Warrants are exercisable, subject to applicable securities laws, at  any
time  prior to May 6, 1998. Each share of Common Stock issued upon exercise of a
Warrant prior to the Distribution Date (as defined in the Rights Agreement)  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. As of December 31, 1994 and 1993,
outstanding Warrants amounted to 2,594,181 and 2,601,619, respectively.

    There  were 33,988 and 27,876 shares of $0.10 par value Common Stock held in
treasury as  of December  31, 1994  and 1993,  respectively. These  shares  were
acquired  through the forfeiture of restricted stock and the surrender of shares
in settlement of tax withholding obligations.

    In the first quarter of 1994, the Corporation completed the Equity  Offering
under which 14,375,000 shares of Common Stock was sold to the public, consisting
of  7,900,000 shares newly issued by the Corporation and 6,475,000 sold by Water
Street. Net proceeds to the Corporation from the newly issued shares amounted to
$224 million. The  Corporation did  not receive any  proceeds from  the sale  of
shares  by Water  Street. See  "Indebtedness" note  for more  information on the
Equity Offering.

LITIGATION

    One of  the  Corporation's  subsidiaries, U.S.  Gypsum,  is  among  numerous
defendants   in  lawsuits   arising  out   of  the   manufacture  and   sale  of
asbestos-containing   building    materials.    U.S.   Gypsum    sold    certain
asbestos-containing products beginning in the 1930's; in most cases the products
were  discontinued or asbestos was removed from the product 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 maintenance  or removal and  replacement of products  containing
asbestos  (the "Property  Damage Cases"). Others  of these  suits (the "Personal
Injury Cases") seek to recover compensatory  and in many cases punitive  damages
for   personal  injury  allegedly  resulting   from  exposure  to  asbestos  and
asbestos-containing products. It is anticipated that additional personal  injury
and property damage cases containing similar allegations will be filed.

    As discussed below, U.S. Gypsum has substantial personal injury and property
damage  insurance for  the years involved  in the asbestos  litigation. Prior to
1985, when  an asbestos  exclusion was  added to  U.S. Gypsum's  policies,  U.S.
Gypsum  purchased  comprehensive general  liability insurance  policies covering
personal injury and property damage in an aggregate face amount of approximately
$850 million. Insurers that issued approximately $106 million of these  policies
are   presently  insolvent.  After  deducting  insolvencies  and  exhaustion  of
policies, approximately $550 million of insurance remains potentially available.
Because U.S. Gypsum's insurance carriers  initially responded to its claims  for
defense  and indemnification with various  theories denying or limiting coverage
and the  applicability  of  their  policies, U.S.  Gypsum  filed  a  declaratory
judgment  action against them in  the Circuit Court of  Cook County, Illinois on
December 29, 1983.  (U. S. GYPSUM  CO. V.  ADMIRAL INSURANCE CO.,  ET AL.)  (the
"Coverage Action"). U.S. Gypsum alleges in the Coverage Action that the carriers
are  obligated to provide indemnification for  settlements and judgments and, in
some cases,  defense  costs incurred  by  U.S.  Gypsum in  property  damage  and
personal  injury claims in which  it is a defendant.  The current defendants are
ten insurance carriers that  provided comprehensive general liability  insurance
coverage to U.S. Gypsum between the 1940's and 1984. As discussed below, several
carriers have settled all or a portion of the claims in the Coverage Action.

    U.S.   Gypsum's   aggregate   out-of-pocket   cash   expenditures   for  all
asbestos-related matters, including property damage, personal injury,  insurance
coverage  litigation and related expenses, exceeded aggregate insurance payments
by $25.8 million in 1992,  $8.2 million in 1993 and  $33.4 million in 1994.  For
the  same periods, the Corporation has  charged $18 million to earnings annually
for all asbestos-related matters, excluding the $30 million charge described  in
"Property Damage Cases" below.

PROPERTY DAMAGE CASES

    The Property Damage Cases have been brought against U.S. Gypsum by a variety
of plaintiffs, including school districts, state and local governments, colleges
and  universities, hospitals  and private  property owners.  As of  December 31,
1994, 41 Property Damage  Cases were pending against  U.S. Gypsum; however,  the
number of buildings involved is greater than the number of cases because many of
these  cases, including  the class actions  referred to  below, involve multiple
buildings. In  addition,  approximately  37 property  damage  claims  have  been
threatened   against  U.S.  Gypsum.  U.S.  Gypsum  has  denied  the  substantive
allegations of each  of the  Property Damage Cases  and intends  to defend  them
vigorously except when advantageous settlements are possible.

    U.S.  Gypsum is one of many defendants in three pending cases that have been
certified as class actions and others that request such certification. On  April
10,  1992, a  state court  in Philadelphia certified  a class  consisting of all
owners of buildings  leased to  the federal government.  (PRINCE GEORGE  CENTER,
INC.  V. U.S. GYPSUM CO.,  ET AL., Court of  Common Pleas, Philadelphia, Pa.) On
September 4, 1992, a Federal district

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
court in  South  Carolina  conditionally  certified a  class  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.).

    In October 1994, U.S. Gypsum executed  agreements to settle two other  class
actions  (one of which has now been closed), subject to court approval following
notice to the respective classes. One suit  was brought on behalf of owners  and
operators  of all  elementary and  secondary schools  in the  United States that
contain or  contained  friable  asbestos-containing material.  (IN  RE  ASBESTOS
SCHOOL LITIGATION, U.S.D.C, E.D. Pa.) Approximately 1,350 school districts opted
out  of the class, some  of which have filed or  may file separate lawsuits. The
other class action  settlement involved  approximately 333  school districts  in
Michigan  that had opted out of the nationwide class action. (BOARD OF EDUCATION
OF THE CITY OF DETROIT, ET AL. V.  THE CELOTEX CORP., ET AL., Circuit Court  for
Wayne County, MI.) The Corporation took a $30 million pre-tax charge to earnings
in   the  fourth  quarter  of  1994   primarily  to  cover  the  cash  payments,
approximately two-thirds of which  was paid in 1994  with the rest payable  over
the next two years. In addition, U.S. Gypsum will also issue discount coupons to
the  school districts in the nationwide class action for the purchase of plaster
products. The coupons, which will be redeemable over ten years subject to annual
"caps," will have  an aggregate face  amount of $50  million. No charge  against
earnings  was  recorded for  future  coupon redemptions.  Such  redemptions will
reduce margins when redeemed, and although  the amount of redemptions cannot  be
estimated, the impact on results of operations is expected to be immaterial. The
Michigan settlement was approved by the Court on December 2, 1994, and no appeal
was  filed.  The settlement  of the  nationwide  class action  has not  yet been
presented to the Court for approval.

    A case  pending  in  state court  in  South  Carolina, which  has  not  been
certified as a class action, purports to be a "voluntary" class action on behalf
of  owners  of all  buildings  containing certain  types  of asbestos-containing
products manufactured by the nine named defendants, including U.S. Gypsum, other
than buildings  owned  by  the  federal  or  state  governments,  single  family
residences,  or  buildings  at  issue  in  the  other  described  class actions.
(ANDERSON COUNTY HOSPITAL V. W.R.  GRACE & CO., ET  AL., Court of Common  Pleas,
Hampton  Co.,  S.C. (the  "Anderson Case")).  The Anderson  Case also  names the
Corporation as a defendant,  alleging, among other  things, that the  guarantees
executed by U.S. Gypsum in connection with the 1988 Recapitalization, as well as
subsequent  distributions of cash from U.S.  Gypsum to the Corporation, rendered
U.S. Gypsum insolvent and constitute a fraudulent conveyance. In July 1994,  the
court  in the Anderson Case ruled  that claims involving building owners outside
South Carolina  cannot be  included in  the suit.  A case  which has  yet to  be
certified  as a class action was filed  in federal court in the Eastern District
of Texas on  August 8,  1994. (KIRBYVILLE  INDEPENDENT SCHOOL  DISTRICT V.  U.S.
GYPSUM,  ET AL., United States District Court for the Eastern District of Texas,
Beaumont Division). The  case purports to  be a  class action on  behalf of  all
public  building  owners  and  political subdivisions  of  the  State  of Texas,
including all cities, counties and  municipalities. The damages claimed  against
U.S. Gypsum in the class action cases are unspecified.

    In  total, U.S. Gypsum  has settled approximately  93 property damage cases,
involving 209 plaintiffs, in addition to the two school class action settlements
referred to above.  Twenty-four cases have  been tried to  verdict, 15 of  which
were  won by U.S.  Gypsum and 5  lost; three other  cases, one won  at the trial
level and two lost, were settled during  appeals. Another case that was lost  at
the  trial court level was  reversed on appeal and  remanded to the trial court,
which has now entered judgment for U.S. Gypsum. Appeals are pending in 3 of  the
tried  cases. In the cases lost,  compensatory damage awards against U.S. Gypsum
have totaled $11.5 million. Punitive damages totalling $5.5 million were entered
against U.S. Gypsum in four trials. Two of the punitive damage awards, totalling
$1.45 million, were  paid after  appeals were  exhausted; and  two were  settled
during the appellate process.

    In 1992, 7 new Property Damage Cases were filed against U.S. Gypsum, 10 were
dismissed  before  trial, 18  were  settled, 3  were  closed following  trial or
appeal, and 76 were pending at year-end. U.S. Gypsum expended $34.9 million  for
the  defense  and resolution  of Property  Damage  Cases and  received insurance

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
payments of $10.2 million in 1992. During 1993, 5 new Property Damage Cases were
filed against U.S. Gypsum, 7 were dismissed before trial, 11 were settled, 1 was
closed following  trial or  appeal, 2  were  consolidated into  1, and  61  were
pending  at year  end; U. S  Gypsum expended  $13.9 million for  the defense and
resolution of  Property Damage  Cases and  received insurance  payments of  $7.6
million  in 1993. In 1994,  5 new Property Damage  Cases were filed against U.S.
Gypsum, 5 were dismissed before trial,  19 were settled, 1 was closed  following
trial  or appeal, and  41 were pending  at year-end. U.S.  Gypsum expended $40.6
million for  the defense  and  resolution of  Property Damage  Cases  (excluding
payments not yet due and future credits for coupon redemption under a 1994 class
action settlement) and received insurance payments of $9 million in 1994.

    In  the Property Damage Cases litigated to date, a defendant's liability for
compensatory damages, if any,  has been limited to  damages associated with  the
presence  and  quantity  of asbestos-containing  products  manufactured  by that
defendant which are identified in the buildings at issue, although plaintiffs in
some cases have  argued that principles  of joint and  several liability  should
apply.  Because of the  unique factors inherent  in each of  the Property Damage
Cases, including the lack of  reliable information as to product  identification
and  the amount of damages claimed against  U.S. Gypsum in many cases, including
the class actions  described above, management  is unable to  make a  reasonable
estimate of the cost of disposing of pending Property Damage Cases.

PERSONAL INJURY CASES

    U.S.  Gypsum was among numerous defendants in asbestos personal injury suits
and administrative claims involving approximately 54,000 claimants pending as of
December 31, 1994  although, as  discussed below, approximately  22,000 of  such
claims are settled but not yet closed. All asbestos bodily injury claims pending
in  the federal courts, including approximately one-third of the Personal Injury
Cases pending against U.S. Gypsum, have  been consolidated in the United  States
District Court for the Eastern District of Pennsylvania.

    U.S.  Gypsum  is  a  member,  together with  19  other  former  producers of
asbestos-containing  products,  of  the   Center  for  Claims  Resolution   (the
"Center").  The  Center  has assumed  the  handling, including  the  defense and
settlement, of all  Personal Injury Cases  pending against U.S.  Gypsum and  the
other  members of the Center. Each member of the Center is assessed a portion of
the liability and  defense costs  of the Center  for the  Personal Injury  Cases
handled  by the Center, according to  predetermined allocation formulas. Five of
U.S. Gypsum's insurance  carriers that  in 1985 signed  an Agreement  Concerning
Asbestos-Related  Claims  (the "Wellington  Agreement") are  supporting insurers
(the "Supporting Insurers") of the Center. The Supporting Insurers are obligated
to provide coverage for the defense and indemnity costs of the Center's  members
pursuant  to the  coverage provisions  in the  Wellington Agreement.  Claims for
punitive damages are defended  but not paid by  the Center; if punitive  damages
are  recovered,  insurance  coverage  may  be  available  under  the  Wellington
Agreement depending on  the terms  of particular policies  and applicable  state
law.  Punitive damages have not  been awarded against U.S.  Gypsum in any of the
Personal Injury Cases. Virtually all of U.S. Gypsum's personal injury  liability
and  defense  costs  are  paid  by those  of  its  insurance  carriers  that are
Supporting Insurers. The Supporting Insurers provided approximately $350 million
of the total  coverage referred to  above, of which  approximately $222  million
remains unexhausted.

    On January 15, 1993, U.S. Gypsum and the other members of the Center entered
into  a class  action settlement  in the  U. S.  District Court  for the Eastern
District of Pennsylvania. (GEORGINE ET AL. V. AMCHEM PRODUCTS INC., ET AL., Case
No. 93-CV-0215; hereinafter  "Georgine.") The class  of plaintiffs includes  all
persons  who have  been occupationally  exposed to  asbestos-containing products
manufactured by the defendants,  who had not filed  an asbestos personal  injury
suit  as of the date of the filing  of the class action. The settlement has been
approved by the  trial court, and  if upheld  on appeal will  implement for  all
future   Personal  Injury  Cases,  except  as  noted  below,  an  administrative
compensation system to replace judicial

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
claims against the defendants, and  will provide fair and adequate  compensation
to future claimants who can demonstrate exposure to asbestos-containing products
manufactured  by the defendants and the presence of an asbestos-related disease.
Approximately 250,000  purported class  members "opted  out," or  elected to  be
excluded  from the settlement, although a substantial portion of such "opt outs"
had previously filed  claims or are  in groups considered  unlikely to  generate
significant  numbers of  future claims. As  of December  31, 1994, approximately
10,000 claims naming U.S. Gypsum as a defendant had been filed by "opt outs." In
addition, in  each year  a limited  number of  class members  will have  certain
rights  to prosecute their claims for compensatory (but not punitive) damages in
court in the event  they reject the compensation  offered by the  administrative
processing of their claim.

    The  Center  members,  including U.S.  Gypsum,  have  instituted proceedings
against those of their insurance carriers that had not consented to support  the
settlement,  seeking a  declaratory judgment  that the  settlement is reasonable
and, therefore, that  the carriers are  obligated to fund  their portion of  it.
Consummation  of the  settlement is contingent  upon, among  other things, court
approval of the settlement  and a favorable ruling  in the declaratory  judgment
proceedings against the non-consenting insurers.

    Each  of  the defendants  has committed  to  fund a  defined portion  of the
settlement, up to a stated maximum amount,  over the initial ten year period  of
the  agreement  (which  is  automatically  extended  unless  terminated  by  the
defendants). Taking  into account  the provisions  of the  settlement  agreement
concerning  the maximum number of claims that must be processed in each year and
the total amount  to be made  available to the  claimants, the Center  estimates
that  U.S. Gypsum  will be  obligated to  fund a  maximum of  approximately $125
million of the class  action settlement, exclusive of  expenses, with a  maximum
payment of less than $18 million in any single year; of the total amount of U.S.
Gypsum's  obligation, all but approximately $7 million is expected to be paid by
U.S. Gypsum's insurance carriers.

    During 1992, approximately 20,100 Personal  Injury Cases were filed  against
U.S.  Gypsum and  approximately 10,600  were settled  or dismissed.  U.S. Gypsum
incurred expenses of $21.6 million in 1992 with respect to Personal Injury Cases
of which $21.5 million was paid by insurance. During 1993, approximately  26,900
Personal  Injury Cases were  filed against U.S.  Gypsum and approximately 22,900
were settled or  dismissed. U.S. Gypsum  incurred expenses of  $34.9 million  in
1993  with respect to Personal  Injury Cases of which  $34.0 million was paid by
insurance. During 1994,  approximately 14,000 Personal  Injury Cases were  filed
against U.S. Gypsum, U.S. Gypsum was added as a defendant in approximately 4,000
cases  that had been previously filed,  and approximately 23,000 were settled or
dismissed. U.S. Gypsum incurred expenses of $38 million in 1994 with respect  to
Personal  Injury  Cases of  which $37.3  million  was paid  by insurance.  As of
December 31, 1994, 1993,  and 1992, 54,000, 59,000,  and 54,000 Personal  Injury
Cases were outstanding against U.S. Gypsum, respectively.

    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 anticipates that its average settlement cost may increase due
to such  factors as  the  possible insolvency  of co-defendants,  although  this
increase  may  be  offset  to  some  extent  by  other  factors,  including  the
possibility for block  settlements of large  numbers of cases  and the  apparent
increase in the percentage of asbestos personal injury cases that appear to have
been  brought by individuals with little  or no physical impairment. Through the
Center, U.S. Gypsum  had reached  settlements on  approximately 22,000  Personal
Injury  Cases pending on  December 31, 1994  for amounts totalling approximately
$32 million, to be expended  over a three to  five year period. In  management's
opinion,  based primarily upon  U.S. Gypsum's experience  in the Personal Injury
Cases  disposed  of  to  date  and   taking  into  consideration  a  number   of
uncertainties,  it is probable  that all asbestos-related  Personal Injury Cases
pending against U.S. Gypsum as  of December 31, 1994, can  be disposed of for  a
total  amount,  including  both indemnity  costs  and legal  fees  and expenses,
estimated to be between $90 million and $100 million (of which all but less than
$5 million is expected to be paid by insurance). The estimated cost of resolving
pending claims  takes into  account,  among other  factors,  (i) the  number  of

                                      F-33

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

pending  claims;  (ii) the  settlements of  certain large  blocks of  claims for
higher per-case averages than have  historically been paid; (iii) the  committed
but unconsummated settlements described above; and (iv) a small increase in U.S.
Gypsum's historical settlement average.

    Assuming  that the  Georgine class  action settlement  referred to  above is
approved substantially  in  its current  form,  management estimates,  based  on
assumptions  supplied by  the Center,  U.S. Gypsum's  maximum total  exposure in
Personal Injury  Cases  during the  next  ten years  (the  initial term  of  the
agreement),  including liability for pending claims  and claims resolved as part
of the class action settlement, as well as defense costs and other expenses,  at
approximately  $250 million, of which approximately  $235 million is expected to
be paid by  insurance. U.S.  Gypsum's additional  exposure for  claims filed  by
persons  who have opted out of Georgine  would depend on the number and severity
of such claims that are filed, which cannot presently be determined.

COVERAGE ACTION

    As indicated above, all of U.S. Gypsum's carriers initially denied  coverage
for  the Property Damage  Cases and the  Personal Injury Cases,  and U.S. Gypsum
initiated the Coverage  Action to  establish its  right to  such coverage.  U.S.
Gypsum  has voluntarily dismissed the Supporting Insurers referred to above from
the personal injury  portion of the  Coverage Action because  they committed  to
providing  personal injury coverage in accordance with the Wellington Agreement.
U.S. Gypsum's  claims  against  the  remaining carriers  for  coverage  for  the
Personal Injury Cases have been stayed since 1984.

    On  January 7,  1991, the trial  court in  the Coverage Action  ruled on the
applicability of U.S. Gypsum's insurance policies to settlements and one adverse
judgment in eight Property  Damage Cases. The court  ruled that the eight  cases
were  generally covered, and  imposed coverage obligations  on particular policy
years based upon the dates when the presence of asbestos-containing material was
"first  discovered"  by  the   plaintiff  in  each   case.  The  court   awarded
reimbursement  of approximately $6.2 million spent by U.S. Gypsum to resolve the
eight cases. U.S. Gypsum appealed the court's ruling with respect to the  policy
years available to cover particular claims, and the carriers appealed most other
aspects of the court's ruling.

    On  November 4, 1994, the Illinois Appellate Court issued a ruling affirming
the trial court's finding that the  eight cases were covered, but expanding  the
years  of coverage  available by holding  that all insurance  policies in effect
from the date  of installation  to the  date of  removal of  asbestos-containing
products are obligated to provide coverage (known as the "continuous trigger" of
coverage).  The  defendant  carriers'  rehearing  petition  was  denied  by  the
Appellate Court in  January 1995.  The defendant carriers  have indicated  their
intention  to seek review by the  Illinois Supreme Court, which is discretionary
with the  Court.  If the  Supreme  Court accepts  the  appeal, the  appeal  will
continue  for a year or more. Once  the appellate process has concluded, further
proceedings will be necessary in the trial court with respect to the application
of the appellate ruling to all Property Damage Cases other than the eight  cases
involved in the earlier trial, as well as resolution of certain other issues.

    The  Appellate  Court's  ruling, if  applied  to the  Property  Damage Cases
generally, will  allow U.S.  Gypsum to  access all  of its  available  insurance
coverage  for Property Damage  Cases, subject to reduction  for amounts that are
spent on Personal  Injury Cases.  Under the  ruling, all  Property Damage  Cases
would  be covered by insurance unless or until such insurance becomes exhausted.
U.S. Gypsum  is evaluating  the impact  of the  ruling on  past property  damage
expenditures  and, if  the ruling is  applied to such  expenditures, U.S. Gypsum
should be able to  recover a substantial portion,  subject to the allocation  of
costs  to insolvent carriers, excess carriers  with no defense cost obligations,
and carriers  that have  previously settled.  The  Company is  not yet  able  to
estimate  the  amount of  its past  property damage  expenditures that  it could
recover or when such recoveries would occur.

    Eight carriers, including two of the Supporting Insurers, have settled  U.S.
Gypsum's  claims for both property damage  and personal injury coverage and have
been dismissed from the Coverage Action entirely.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
Four of these  carriers agreed  to pay  all or  a substantial  portion of  their
policy limits to U.S. Gypsum beginning in 1991 and continuing over the following
four  years. Three other excess carriers,  including the two settling Supporting
Insurers, have agreed to provide coverage for the Property Damage Cases and  the
Personal Injury Cases subject to certain limitations and conditions, when and if
underlying  primary and  excess coverage is  exhausted. Taking  into account the
above settlements, including participation of  certain of the settling  carriers
in the Wellington Agreement, and consumption through December 31, 1994, carriers
providing  a total  of approximately $81  million of  unexhausted insurance have
agreed, subject to the terms of the various settlement agreements, to cover both
Personal  Injury  Cases  and  Property  Damage  Cases.  Carriers  providing   an
additional $210 million of coverage that was unexhausted as of December 31, 1994
have  agreed to cover Personal Injury  Cases under the Wellington Agreement, but
continue to contest coverage for Property Damage Cases and remain defendants  in
the  Coverage Action. U.S. Gypsum continues  to seek negotiated resolutions with
its carriers in order to minimize the expense and delays of litigation.

    Insolvency proceedings have been instituted  against four of U. S.  Gypsum's
insurance  carriers.  Midland  Insurance Company,  declared  insolvent  in 1986,
provided excess insurance ($4  million excess of $1  million excess of  $500,000
primary  in  each policy  year) from  February  15, 1975  to February  15, 1978;
Transit Casualty Company, declared insolvent in 1985, provided excess  insurance
($15  million excess of $1  million primary in each  policy year) from August 1,
1980 to December 31,  1985; Integrity Insurance  Company, declared insolvent  in
1986,  provided excess insurance ($10 million  quota share of $25 million excess
of $90  million) from  August 1,  1983 to  July 31,  1984; and  American  Mutual
Insurance  Company, declared  insolvent in 1989,  provided the  primary layer of
insurance ($500,000 per year)  from February 1,  1963 to April  15, 1971. It  is
possible  that U.S.  Gypsum will be  required to pay  a presently indeterminable
portion of the costs that would  otherwise have been covered by these  policies.
In  addition, portions  of various policies  issued by Lloyd's  and other London
market companies between  1966 and 1979  have also become  insolvent; under  the
Wellington   Agreement,  U.S.  Gypsum  must   pay  these  amounts,  which  total
approximately $12 million.

    It is not  possible to predict  the number of  additional lawsuits  alleging
asbestos-related  claims that  may be filed  against U.S.  Gypsum. Many Property
Damage Cases are still at an  early stage and the potential liability  therefrom
is  consequently uncertain. In  view of the  limited insurance funding currently
available for the Property Damage Cases resulting from the continued  resistance
by  a number of U.S. Gypsum's insurers  to providing coverage, the effect of the
asbestos litigation on the  Corporation will depend upon  a variety of  factors,
including the damages sought in the Property Damage Cases that reach trial prior
to  the completion of the Coverage Action, U.S. Gypsum's ability to successfully
defend or settle such  cases, and the  resolution of the  Coverage Action. As  a
result,  management is  unable to  determine whether  an adverse  outcome in the
asbestos litigation  will have  a  material adverse  effect  on the  results  of
operations or the consolidated financial position of the Corporation.

ACCOUNTING CHANGE

    Effective  January  1, 1994,  the  Corporation adopted  the  requirements of
Financial Accounting  Standards  Board Interpretation  No.  39  ("Interpretation
39").  In accordance with Interpretation 39, U.S. Gypsum recorded an accrual for
its liabilities for asbestos-related matters  which are deemed probable and  can
be reasonably estimated, and separately recorded an asset equal to the amount of
such  liabilities that is expected  to be paid by  uncontested insurance. Due to
management's inability  to  reasonably  estimate  U.S.  Gypsum's  liability  for
Property  Damage  Cases  and (until  the  implementation of  Georgine  is deemed
probable) future Personal Injury Cases, the liability and asset recorded in 1994
relate only  to pending  Personal Injury  Cases. As  of December  31, 1994,  the
liability (which is included in other liabilities on the

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
consolidated  balance sheet) and the asset (which is included in other assets on
the consolidated balance sheet) for pending Personal Injury Cases each  amounted
to  $100  million.  This  implementation of  Interpretation  39  did  not impact
earnings, cash flow or net assets.

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 substantially all 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  estimable 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.

INDUSTRY AND GEOGRAPHIC SEGMENTS
    Transactions between geographic areas are accounted for on an "arm's-length"
basis.  No single customer accounted  for 4% or more  of consolidated net sales.
Export sales  to  foreign unaffiliated  customers  represent less  than  10%  of
consolidated net sales.

    Intrasegment  and  intersegment  eliminations  largely  reflect intercompany
sales. Segment operating profit/(loss) includes all costs and expenses  directly
related to the segment involved and an allocation of expenses which benefit more
than  one segment.  Segment operating  profit/(loss) also  includes the non-cash
amortization of excess  reorganization value  which had the  impact of  reducing
operating  profit.  Assets  for  USG Funding,  which  was  established  in 1994,
represent the outstanding balance of receivables purchased from U.S. Gypsum  and
USG  Interiors, net  of reserves,  and are  included in  "corporate identifiable
assets" in the table below.  As of December 31,  1994, such receivables, net  of
reserves,  amounted to $123  million, including $84  million purchased from U.S.
Gypsum and $39 million purchased from USG Interiors. Information for the  period
of  May 7  through December  31, 1993,  shown in  the following  tables has been
restated to conform to the Corporation's current industry segment organization.

guarantee  is limited to the greater of (i) 95% of the lowest amount, calculated
as of July  13, 1988, sufficient  to render the  guarantor insolvent, leave  the
guarantor  with unreasonably small capital or  leave the guarantor unable to pay
its debts as they become due (each as defined under applicable law) and (ii) the
same amount,  calculated  as of  the  date any  demand  for payment  under  such
guarantee is made, in each case plus collection costs. The guarantees are senior
obligations   of  the  applicable  guarantor  and   rank  PARI  PASSU  with  all
unsubordinated obligations of the guarantor.

    Subsidiaries   other   than   the   Combined   Guarantors   (the   "Combined
Non-Guarantors"),  substantially all  of which  are subsidiaries  of guarantors,
primarily include CGC, Gypsum Transportation Limited, USG Canadian Mining  Ltd.,
and the Corporation's Mexican, European and Pacific subsidiaries. USG Funding is
also  a Non-Guarantor. The long-term debt  of the Combined Non-Guarantors of $84
million and $24  million as  of December 31,  1994 and  1993, respectively,  has
restrictive  covenants  that  restrict,  among  other  things,  the  payment  of
dividends.

    The following condensed consolidating information presents:

(i)  Condensed financial statements  as of December 31,  1994 and 1993, for  the
    year  ended December 31, 1994  and for the period  of May 7 through December
    31, 1993 of: (a) the Corporation on a parent company only basis (the "Parent
    Company," which  was the  only entity  of the  Corporation included  in  the
    bankruptcy  proceeding);  (b)  the  Combined  Guarantors;  (c)  the Combined
    Non-Guarantors; and (d) the Corporation on a consolidated basis. Due to  the
    Restructuring  and implementation  of fresh start  accounting, the financial
    statements for the restructured company (periods after May 6, 1993) are  not
    comparable  to those  of the predecessor  company. Except  for the following
    condensed financial statements, separate financial information with  respect
    to the Combined Guarantors is omitted as such separate financial information
    is not deemed material to investors.

(ii)  The Parent Company and Combined Guarantors shown with their investments in
    their subsidiaries accounted for on the equity method.

(iii) Elimination entries necessary  to consolidate the  Parent Company and  its
    subsidiaries.

                               MANAGEMENT REPORT

    Management is responsible for the preparation and integrity of the financial
statements  and  related  notes  included  herein.  These  statements  have been
prepared in accordance  with generally  accepted accounting  principles and,  of
necessity,  include some amounts  that are based  on management's best estimates
and judgments.

    The Corporation's accounting systems  include internal controls designed  to
provide reasonable assurance of the reliability of its financial records and the
proper  safeguarding  and  use  of  its  assets.  Such  controls  are  based  on
established policies and procedures, are  implemented by trained personnel,  and
are  monitored through an internal audit program. The Corporation's policies and
procedures prescribe that the Corporation  and its subsidiaries are to  maintain
ethical  standards and  that its  business practices  are to  be consistent with
those standards.

    The Audit Committee of the Board, consisting solely of outside Directors  of
the  Corporation, maintains an ongoing appraisal, on behalf of the stockholders,
of the effectiveness of the independent auditors and management with respect  to
the  preparation of financial statements, the  adequacy of internal controls and
the Corporation's accounting policies.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Stockholders and Board
 of Directors of USG Corporation:

We have audited the accompanying consolidated balance sheets of USG  Corporation
(Restructured  Company), a Delaware corporation, and subsidiaries as of December
31, 1994 and 1993 and the  related consolidated statements of earnings and  cash
flows  for the  year ended  December 31, 1994  and the  period of  May 7 through
December 31,  1993. 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.

As discussed in Notes to Financial Statements -- "Financial Restructuring" note,
on  May  6,   1993,  the   Corporation  completed   a  comprehensive   financial
restructuring through the implementation of a prepackaged plan of reorganization
under  Chapter 11 of the  United States Bankruptcy Code  and applied fresh start
accounting. As  such, results  of operations  through May  6, 1993  (Predecessor
Company) are not comparable with results of operations subsequent to that date.

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,  1994  and  1993, and  the  results  of their
operations and their cash  flows for the  year ended December  31, 1994 and  the
period of May 7 through December 31, 1993, in conformity with generally accepted
accounting principles.

As  discussed in Notes to Financial Statements  -- "Litigation" note, in view of
the limited  insurance funding  currently available  for property  damage  cases
resulting from the continued resistance by a number of U.S. Gypsum's insurers to
providing  coverage, the  effect of the  asbestos litigation  on the Corporation
will depend upon a variety of factors, including the damages sought in  property
damage  cases that reach trial  prior to the completion  of the coverage action,
U.S. Gypsum's  ability to  successfully defend  or settle  such cases,  and  the
resolution  of  the  coverage  action.  As a  result,  management  is  unable to
determine whether an  adverse outcome  in the  asbestos litigation  will have  a
material  adverse  effect  on  the consolidated  results  of  operations  or the
consolidated financial position of the Corporation.

As discussed in Notes to Financial  Statements -- "Litigation" note, on  January
1,  1994, the Corporation changed its  method of accounting for asbestos-related
matters.

currency  translation losses were charged to earnings. Purchased goodwill, which
was written off in accordance with the implementation of fresh start accounting,
was previously being amortized over a period of 40 years.

    For purposes of the Consolidated Balance Sheet and Consolidated Statement of
Cash Flows, all  highly liquid investments  with a maturity  of three months  or
less at the time of purchase are considered to be cash equivalents.

FINANCIAL RESTRUCTURING

    On  May 6, 1993, the Corporation  completed a comprehensive restructuring of
its debt (the "RESTRUCTURING") through implementation of a "prepackaged" plan of
reorganization under United States bankruptcy  law (the "PREPACKAGED PLAN").  In
accordance  with the  terms of  the Prepackaged Plan,  $1.4 billion  of debt and
accrued interest was converted into  equity, interest expense was  significantly
reduced  and  the  maturities  of a  substantial  portion  of  the Corporation's
remaining debt were  extended. The Corporation  accounted for the  Restructuring
using the principles of fresh start accounting as required by AICPA Statement of
Position  90-7,  "Financial Reporting  by Entities  in Reorganization  under the
Bankruptcy Code" ("SOP  90-7"). Pursuant to  such principles, individual  assets
and  liabilities were adjusted  to fair market  value as of  May 6, 1993. Excess
reorganization value, the portion of  the reorganization value not  attributable
to specific assets, is being amortized over a five-year period, effective May 7,
1993.

    The following balance sheet details the adjustments that were made as of May
6, 1993 to record the Restructuring and implement fresh start accounting:

CUMULATIVE EFFECT OF CHANGES IN ACCOUNTING PRINCIPLES

    A  one-time  after-tax charge  of  $150 million  was  recorded in  the first
quarter of 1993 representing the  adoption of Statement of Financial  Accounting
Standard  ("SFAS") No.  106, "Employers' Accounting  for Postretirement Benefits
Other Than Pensions," -- $180 million, partially offset by the adoption of  SFAS
No.  109, "Accounting  for Income  Taxes," --  $30 million.  See "Postretirement
Benefits" and "Taxes on Income and Deferred Taxes" notes for information on  the
adoption of these standards. Neither of these standards impact cash flow.

RESEARCH AND DEVELOPMENT

    Research  and development expenditures  are charged to  earnings as incurred
and amounted to $4 million  and $14 million in the  period of January 1  through
May 6, 1993 and the year ended December 31, 1992, respectively.

TAXES ON INCOME AND DEFERRED INCOME TAXES

    Effective January 1, 1993, the Corporation adopted SFAS No. 109, "Accounting
for  Income Taxes." The cumulative effect as of January 1, 1993 of adopting SFAS
No. 109  was a  one-time  benefit to  first quarter  1993  net earnings  of  $30
million,  primarily due to  adjusting deferred taxes  from historical to current
tax rates. Financial statements  for periods prior to  January 1, 1993 have  not
been restated to reflect the adoption of this standard.

    Earnings/(loss)  before taxes on  income, extraordinary gain  and changes in
accounting principles consisted of the following (dollars in millions):

</TABLE>

    A  valuation allowance has been provided for deferred tax assets relating to
pension and  retiree medical  benefits  due to  the  long-term nature  of  their
realization. Because of the uncertainty regarding the application of the Code to
the  Corporation's NOL  Carryforwards as  a result  of the  Prepackaged Plan, no
deferred tax asset is recorded.

    The Corporation has NOL  Carryforwards of $113  million remaining from  1992
after a reduction due to cancellation of indebtedness from the Prepackaged Plan.
These  NOL Carryforwards may be used to offset U.S. taxable income through 2007.
The Code will limit the Corporation's annual use of its NOL Carryforwards to the
lesser of its taxable income or approximately $30 million plus any unused  limit
from  prior years. Furthermore, due to the uncertainty regarding the application
of  the  Code  to  the  exchange  of  stock  for  debt,  the  Corporation's  NOL
Carryforwards  could be further reduced or  eliminated. The Corporation has a $3
million minimum  tax  credit  which may  be  used  to offset  U.S.  regular  tax
liability in future years.

    During 1992, deferred income taxes resulted from certain items being treated
differently  for financial reporting purposes than  for income tax purposes. The
tax effect of such differences is summarized as follows (dollars in millions):

    The Corporation  does not  provide  for U.S.  Federal  income taxes  on  the
portion  of undistributed earnings of foreign subsidiaries which are intended to
be permanently reinvested. The cumulative amount of such undistributed  earnings
totaled  approximately $75 million as of May 6, 1993. Any future repatriation of
undistributed earnings  would  not, in  the  opinion of  management,  result  in
significant additional taxes.

INVENTORIES

    In accordance with the implementation of fresh start accounting, inventories
were  stated at fair market  value as of May 6,  1993. Most of the Corporation's
domestic and Mexican inventories are valued under the LIFO method. As of May  6,
1993, the LIFO values of these inventories were $103 million and would have been
the same if they were valued under the FIFO and average production cost methods.
Inventories  include  material,  labor and  applicable  factory  overhead costs.
Inventory classifications were as follows (dollars in millions):

    The LIFO value  of U.S.  domestic inventories under  fresh start  accounting
exceeded that computed for U.S. Federal income tax purposes by $26 million as of
May 6, 1993.

PROPERTY, PLANT AND EQUIPMENT

    Property,  plant and equipment were stated at fair market value as of May 6,
1993 in accordance with fresh start accounting. Provisions for depreciation  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. Interest during construction is capitalized
on major property additions. Property, plant and equipment classifications  were

</TABLE>

    As  of May 6, 1993, the Corporation  and its subsidiaries had $1,556 million
total principal amount of debt (before unamortized reorganization discount) on a
consolidated  basis.  Of  such  total  debt,  $118  million  represented  direct
borrowings  by  the subsidiaries,  including $38  million of  industrial revenue
bonds, $41 million of 7  7/8% sinking fund debentures  issued by U.S. Gypsum  in
1974 and subsequently assumed by the Corporation on a joint and several basis in
1985,  $33  million  of  debt  (primarily  project  financing)  incurred  by the
Corporation's foreign subsidiaries other than CGC, $4 million of working capital
borrowings by CGC, and $3 million of other long-term borrowings by CGC.

    The Bank Debt and most other senior debt  are secured by a pledge of all  of
the  shares  of the  Corporation's major  domestic subsidiaries  and 65%  of the
shares of certain  of its  foreign subsidiaries,  including CGC,  pursuant to  a
collateral  trust arrangement controlled  primarily by holders  of the Bank Term
Loans. The rights  of the Corporation  and its  creditors to the  assets of  any
subsidiary  upon the latter's  liquidation or reorganization  will be subject to
the prior claims of such subsidiary's  creditors, except to the extent that  the
Corporation  may  itself  be a  creditor  with enforceable  claims  against such
subsidiary. The  average rate  of interest  on the  Bank Term  Loans,  excluding
default  interest which was  cured or waived in  accordance with the Prepackaged
Plan, was 6.5%  in the  period of January  1 through  May 6, 1993.  The rate  of
interest on certain capitalized interest notes issued under the Credit Agreement
on  May 6, 1993  in connection with  the provisions of  the Prepackaged Plan was
5.4% based on LIBOR plus 2 1/4%.

    The "other  secured  debt"  category  shown in  the  table  above  primarily
includes  short-term and long-term borrowings from  several foreign banks by USG
International used principally to finance  construction of the Aubange,  Belgium
ceiling  tile plant. This debt is secured by a lien on the assets of the Aubange
plant and  has restrictive  covenants  that restrict,  among other  things,  the
payment of dividends. Foreign borrowings made by the Corporation's international
operations are generally allowed, within certain limits, under provisions of the
Credit Agreement.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

    In  general,  the  Credit  Agreement  restricts,  among  other  things,  the
incurrence of additional indebtedness, mergers, asset dispositions, investments,
prepayment of  other  debt,  dealings  with  affiliates,  capital  expenditures,
payment of dividends and lease commitments.

    The fair market value of debt as of May 6, 1993 was $1,421 million, based on
estimates  of fair market value calculated  in connection with implementation of
fresh start  accounting, excluding  other secured  debt, primarily  representing
financing for construction of the Aubange plant that is secured by a direct lien
on its assets, which was not practicable to estimate.

    The  weighted average interest rate on outstanding short-term borrowings was
7.3% as of May 6, 1993.

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  last  years  of
employment.  The  Corporation's  contributions  are  made  in  accordance   with
independent actuarial reports which, for most plans, required minimal funding in
the  period of  January 1 through  May 6, 1993  and the year  ended December 31,
1992.  Net  pension  expense  included  the  following  components  (dollars  in
millions):

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.

    Effective January 1, 1993, the Corporation adopted SFAS No. 106, "Employers'
Accounting for Postretirement  Benefits Other  Than Pensions,"  for its  retiree
benefit  plans. Under this  accounting standard, the  Corporation is required to
accrue the estimated cost of  retiree benefit payments during employees'  active
service  period. The Corporation elected to  recognize this change in accounting
principle on  the  immediate recognition  basis.  The cumulative  effect  as  of
January  1, 1993  of adopting SFAS  No. 106  was a one-time  after-tax charge to
first quarter  1993 net  earnings of  $180 million.  The Corporation  previously
expensed the cost of these benefits, which principally relate to health care, as
claims were incurred. These costs were $8 million in the year ended December 31,
1992.

    The following table summarizes the components of net periodic postretirement
benefit  cost  for the  period  of January  1 through  May  6, 1993  (dollars in

    The  assumed health care  cost trend rate used  in measuring the accumulated
postretirement benefit obligation  was 13% as  of May 6,  1993 with a  gradually
declining  rate to 6% by the year 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 as of
May  6, 1993 by $18 million and increase the net periodic postretirement benefit
cost for the period of January 1 through May 6, 1993 by $1 million. The  assumed
discount  rate  used  in  determining  the  accumulated  postretirement  benefit
obligation was 8%.

MANAGEMENT PERFORMANCE PLAN

    The Management Performance  Plan reserved 8,600,000  shares of Common  Stock
for  issuance in connection with grants of incentive stock options, nonqualified
stock options,  stock appreciation  rights,  restricted stock,  deferred  stock,
performance shares and performance units.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

    In  accordance with the Prepackaged Plan, all outstanding stock options (for
3,786,575 shares)  were cancelled  without  consideration, 1,016,090  shares  of
restricted  and deferred stock  were cashed-out pursuant  to "change in control"
provisions contained in the  Management Performance Plan,  and 25,580 shares  of
restricted  stock  and  awards for  deferred  stock  yet to  be  issued remained
outstanding as a consequence of certain  waivers of the change in control  event
by senior members of management.

    The  Prepackaged Plan limited future awards under the Management Performance
Plan without stockholder approval to options to purchase a number of shares  not
to  exceed 7.5% of the number of  shares of Common Stock outstanding immediately
after implementation  of  the  Prepackaged Plan  (2,788,350  shares),  of  which
options for 4.5% of such number of outstanding shares may be granted immediately
upon consummation of the Prepackaged Plan.

PREFERRED SHARE PURCHASE RIGHTS

    On  June 6, 1988, the Corporation  adopted a Preferred Share Purchase Rights
Plan and pursuant to its provisions declared, subject to the consummation of the
1988 Recapitalization, the  distribution of  one Right  upon each  new share  of
Common  Stock  issued in  the 1988  Recapitalization. The  1988 Recapitalization
became effective  July  13,  1988  and  the  distribution  occurred  immediately
thereafter.  The  Rights  contain  provisions  which  are  intended  to  protect
stockholders in the event of an unsolicited attempt to acquire the Corporation.

    The Preferred Share Purchase Rights  Plan was terminated in connection  with
implementation of the Prepackaged Plan. On May 6, 1993, the Rights Agreement was
adopted with provisions substantially similar to the old rights except that: (i)
the  purchase price of the  Rights was reset; (ii)  the expiration of the Rights
was extended;  (iii) a  so-called  "flip-in" feature  and exchange  feature  was
added;  (iv) certain exemptions  were added permitting  certain acquisitions and
the continued holding  of common shares  by Water Street  and its affiliates  in
excess  of  the otherwise  specified thresholds;  (v)  the redemption  price was
reduced; and (vi) the amendment provision was liberalized.

    The Rights 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 which  the  Corporation's Board  of Directors  determines  to
represent a threat of acquisition not in the best interests of the Corporation's
stockholders).  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 $35.00  per one-
hundredth of a preferred share, subject to adjustment.

    In the  event that  the Corporation  is the  surviving corporation  and  the
Common  Stock remains  outstanding and unchanged  in a merger  or other business
combination such acquiring  party or  the acquiring party  engages in  one of  a
number  of  self-dealing transactions  specified in  the Rights  Agreement, each
holder of a Right other than the acquiring party will thereafter have the  right
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.

WARRANTS

    On  May 6, 1993, a total of 2,602,566 Warrants, in addition to Common Stock,
were issued to  holders of certain  debt which  was converted to  equity in  the
Restructuring.  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.

    The  Warrants are exercisable, subject to applicable securities laws, at any
time prior to May 6, 1998. Each share of Common Stock issued upon exercise of  a
Warrant prior to the distribution date as defined in

    As of May 6,  1993, the Corporation  held 27,556 shares  of $0.10 par  value

forfeiture of restricted stock.

LITIGATION

    INFORMATION IN THE  FOLLOWING "LITIGATION" NOTE  IS AS OF  MAY 6, 1993.  SEE
"RESTRUCTURED  COMPANY -- NOTES TO FINANCIAL  STATEMENTS -- LITIGATION" NOTE FOR
CURRENT LITIGATION INFORMATION.

    One of  the  Corporation's  subsidiaries, U.S.  Gypsum,  is  among  numerous
defendants   in  lawsuits   arising  out   of  the   manufacture  and   sale  of
asbestos-containing   building    materials.    U.S.   Gypsum    sold    certain
asbestos-containing products beginning in the 1930's; in most cases the products
were  discontinued or asbestos was removed from the product 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 maintenance  or removal and  replacement of products  containing
asbestos (the

                                      F-60
<PAGE>
                                USG CORPORATION
                             (PREDECESSOR COMPANY)
                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
"Property  Damage Cases"). Others  of these suits  (the "Personal Injury Cases")
seek to recover  compensatory and in  many cases punitive  damages for  personal
injury  allegedly resulting  from exposure  to asbestos  and asbestos-containing
products. It is anticipated that additional personal injury and property  damage
cases containing similar allegations will be filed.

    As discussed below, U.S. Gypsum has substantial personal injury and property
damage  insurance for  the years involved  in the asbestos  litigation. Prior to
1985, when  an asbestos  exclusion was  added to  U.S. Gypsum's  policies,  U.S.
Gypsum  purchased  comprehensive general  liability insurance  policies covering
personal injury and property damage in an aggregate face amount of approximately
$850 million. As of May 6, 1993, insurers that issued approximately $100 million
of these  policies  were insolvent.  Because  U.S. Gypsum's  insurance  carriers
initially  responded to its claims for  defense and indemnification with various
theories denying or limiting coverage  and the applicability of their  policies,
U.S.  Gypsum filed  a declaratory  judgment action  against them  in the Circuit
Court of Cook County, Illinois on December 29, 1983. (U.S. GYPSUM CO. V. ADMIRAL
INSURANCE CO.,  ET AL.)  (the "Coverage  Action"). U.S.  Gypsum alleges  in  the
Coverage  Action that the carriers are  obligated to provide indemnification for
settlements and judgments  and, in some  cases, defense costs  incurred by  U.S.
Gypsum  in personal injury and property damage cases in which it is a defendant.
The current defendants  are ten insurance  carriers that provided  comprehensive
general liability insurance coverage to U.S. Gypsum between the 1940's and 1984.
As discussed below, several carriers have settled all or a portion of the claims
in the Coverage Action.

    U.S.  Gypsum's  aggregate  expenditures  for  all  asbestos-related matters,
including property damage,  personal injury, insurance  coverage litigation  and
related  expenses, exceeded aggregate insurance payments by $25.8 million in the
year ended December 31,  1992, and by  $3.8 million in the  period of January  1
through May 6, 1993.

PROPERTY DAMAGE CASES

    The Property Damage Cases have been brought against U.S. Gypsum by a variety
of plaintiffs, including school districts, state and local governments, colleges
and  universities, hospitals,  and private property  owners. As of  May 6, 1993,
U.S. Gypsum was one of many defendants in four cases that had been certified  as
class  actions and  others that requested  such certification.  One class action
suit is  brought  on  behalf of  owners  and  operators of  all  elementary  and
secondary  schools  in  the  United States  that  contain  or  contained friable
asbestos-containing material. (IN RE ASBESTOS SCHOOL LITIGATION, U.S.D.C.,  E.D.
Pa.)  Approximately 1,350 school districts opted out of the class, some of which
have filed or may file  separate lawsuits or are  participants in a state  court
class action involving approximately 333 school districts in Michigan. (BOARD OF
EDUCATION  OF THE CITY OF DETROIT, ET AL. V. THE CELOTEX CORP., et al., Cir. Ct.
for Wayne  County, Mich.)  On April  10,  1992, a  state court  in  Philadelphia
certified  a class consisting of  all owners of buildings  leased to the federal
government. (PRINCE  GEORGE CENTER,  INC. V.  U.S. GYPSUM  CO., ET  AL., Ct.  of
Common  Pleas, Philadelphia, Pa.) On September 4, 1992, a Federal district court
in South Carolina conditionally certified a class 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.). On December 23, 1992,  a
case  was filed in state court in  South Carolina purporting to be a "voluntary"
class action on behalf  of owners of all  buildings containing certain types  of
asbestos-containing   products  manufactured  by   the  nine  named  defendants,
including U.S.  Gypsum, other  than  buildings owned  by  the federal  or  state
governments,  single family residences, or buildings  at issue in the four above
described class actions (ANDERSON COUNTY HOSPITAL  V. W.R. GRACE & CO., ET  AL.,
Court  of Common Pleas, Hampton Co., S.C.  (the "Anderson Case"). On January 14,
1993,  the  plaintiff  filed  an  amended  complaint  that  added  a  number  of
defendants,  including  the Corporation.  The  amended complaint  alleges, among
other things, that the guarantees executed by U.S. Gypsum in connection with the
1988 Recapitalization, as  well as  subsequent distributions of  cash from  U.S.
Gypsum  to  the Corporation,  rendered U.S.  Gypsum  insolvent and  constitute a
fraudulent  conveyance.  The  suit  seeks  to  set  aside  the  guarantees   and

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
recover  the  value  of  the  cash  flow  "diverted"  from  U.S.  Gypsum  to the
Corporation in an amount to be determined. This case has not been certified as a
class action and no other threshold issues, including whether the South Carolina
Courts have personal jurisdiction over the  Corporation, had been decided as  of
May  6, 1993. The damages claimed against  U.S. Gypsum in the class action cases
are unspecified. U.S. Gypsum has denied  the substantive allegations of each  of
the  Property Damage  Cases and  intends to  defend them  vigorously except when
advantageous settlements are possible.

    As of  May 6,  1993, 67  Property  Damage Cases  were pending  against  U.S.
Gypsum;  however, the number of buildings involved is greater than the number of
cases because  many of  these cases,  including the  class actions  referred  to
above,  involve multiple buildings. Approximately 40 property damage claims were
threatened against U.S. Gypsum.

    In total, as of May 6, 1993, U.S. Gypsum had settled property damage  claims
of  approximately 187 plaintiffs involved  in approximately 71 cases. Twenty-two
cases had been tried to verdict, 13 of which were won by U.S. Gypsum and 7 lost;
two other cases, one  won at the  trial level and one  lost, were settled  after
appeals.  Appeals  were pending  in 4  of the  tried cases.  In the  cases lost,
compensatory damage awards against U.S.  Gypsum totaled $12.5 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  after
appeals  were exhausted; a third  was settled after the  verdict was reversed on
appeal. As of May 6, 1993, the remaining punitive award was on appeal.

    In 1991, 13  new Property Damage  Cases were filed  against U.S. Gypsum,  11
were  dismissed before trial, 8  were settled, 2 were  closed following trial or
appeal, and 100 were pending at year end; U.S. Gypsum expended $22.2 million for
the defense  and resolution  of  Property Damage  Cases and  received  insurance
payments  of $13.8 million  in 1991. In  1992, 7 new  Property Damage Cases were
filed against U.S. Gypsum,  10 were dismissed before  trial, 18 were settled,  3
were  closed following trial  or appeal, and  76 were pending  at year end. U.S.
Gypsum expended $34.9 million for the defense and resolution of Property  Damage
Cases and received insurance payments of $10.2 million in 1992. In the period of
January  1 through May 6, 1993, no  new Property Damage Cases were filed against
U.S. Gypsum, 2 were dismissed before trial, 7 were settled, and 67 were  pending
at  the end of the period. U.S. Gypsum expended $7.0 million for the defense and
resolution of  Property Damage  Cases and  received insurance  payments of  $3.7
million in the period.

    In  the Property Damage Cases litigated to date, a defendant's liability for
compensatory damages, if any,  has been limited to  damages associated with  the
presence  and  quantity  of asbestos-containing  products  manufactured  by that
defendant which are identified in the buildings at issue, although plaintiffs in
some cases have  argued that principles  of joint and  several liability  should
apply.  Because of the  unique factors inherent  in each of  the Property Damage
Cases, including the lack of  reliable information as to product  identification
and  the amount of damages claimed against  U.S. Gypsum in many cases, including
the class actions  described above, management  is unable to  make a  reasonable
estimate of the cost of disposing of pending Property Damage Cases.

PERSONAL INJURY CASES

    U.S.  Gypsum was among numerous defendants in asbestos personal injury suits
and administrative claims involving 57,645 claimants pending as of May 6,  1993.
All  asbestos  bodily injury  claims pending  in  the federal  courts, including
approximately one-third  of  the  Personal Injury  Cases  pending  against  U.S.
Gypsum,  have  been consolidated  in the  United States  District Court  for the
Eastern District of Pennsylvania.

    U.S. Gypsum  is  a  member,  together with  19  other  former  producers  of
asbestos-containing   products,  of  the  Center   for  Claims  Resolution  (the
"Center"). The  Center  has assumed  the  handling, including  the  defense  and
settlement,  of all  Personal Injury Cases  pending against U.S.  Gypsum and the
other members of the Center. Each member of the Center is assessed a portion  of
the liability and defense costs of the

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
Center  for  the  Personal Injury  Cases  handled  by the  Center,  according to
predetermined allocation formulas. Five of U.S. Gypsum's insurance carriers that
in 1985 signed an Agreement Concerning Asbestos-Related Claims (the  "Wellington
Agreement")  are supporting insurers (the  "Supporting Insurers") of the Center.
The Supporting Insurers are  obligated to provide coverage  for the defense  and
indemnity  costs of the Center's members  pursuant to the coverage provisions in
the Wellington Agreement. Claims for punitive damages are defended but not  paid
by  the Center;  if punitive  damages are  recovered, insurance  coverage may be
available under the Wellington  Agreement depending on  the terms of  particular
policies  and  applicable  state law.  Punitive  damages have  not  been awarded
against U.S. Gypsum in any of the  Personal Injury Cases. Virtually all of  U.S.
Gypsum's  personal injury liability and  defense costs are paid  by those of its
insurance  carriers  that  are  Supporting  Insurers.  The  Supporting  Insurers
provided approximately $350 million of the total coverage referred to above.

    On  January 15, 1993, U.S.  Gypsum and the other  members of the Center were
named as defendants in a class action  filed in the U.S. District Court for  the
Eastern  District Pennsylvania (GEORGINE ET AL. V. AMCHEM PRODUCTS INC., ET AL.,
Case No. 93-CV-0215) (hereinafter "Georgine,"). The complaint generally  defines
the  class of plaintiffs as all persons  who have been occupationally exposed to
asbestos-containing products  manufactured by  the defendants  and who  had  not
filed an asbestos personal injury suit as of the date of the filing of the class
action.  Simultaneously with the filing of the class action, the parties filed a
settlement agreement in which the named plaintiffs, proposed class counsel,  and
the defendants agreed to settle and compromise the claims of the proposed class.
The  settlement,  which was  awaiting court  approval  as of  May 6,  1993, will
implement for  all future  Personal  Injury Cases,  except  as noted  below,  an
administrative  compensation  system  to  replace  judicial  claims  against the
defendants, and will provide fair and adequate compensation to future  claimants
who can demonstrate exposure to asbestos-containing products manufactured by the
defendants  and the presence of an  asbestos-related disease. Class members will
be given  the  opportunity to  "opt  out," or  elect  to be  excluded  from  the
settlement,  although  the defendants  reserve the  right  to withdraw  from the
settlement if the number of opt outs  is, in their sole judgment, excessive.  In
addition, in each year a limited number of claimants will have certain rights to
prosecute  their claims for compensatory (but  not punitive) damages in court in
the event they reject compensation  offered by the administrative processing  of
their claim.

    The  Center  members,  including U.S.  Gypsum,  have  instituted proceedings
against those of their insurance carriers that had not consented to support  the
settlement,  seeking a  declaratory judgment  that the  settlement is reasonable
and, therefore, that  the carriers are  obligated to fund  their portion of  it.
Consummation  of the  settlement is contingent  upon, among  other things, court
approval of the settlement  and a favorable ruling  in the declaratory  judgment
proceedings  against the non-consenting insurers. It is anticipated that appeals
will follow the district  court's ruling on the  fairness and reasonableness  of
the settlement.

    Each  of  the defendants  has committed  to  fund a  defined portion  of the
settlement, up to a stated maximum  amount, over the initial ten-year period  of
the  agreement  (which  is  automatically  extended  unless  terminated  by  the
defendants). Taking  into account  the provisions  of the  settlement  agreement
concerning  the maximum number of claims that must be processed in each year and
the total amount  to be made  available to the  claimants, the Center  estimates
that  U.S. Gypsum  will be  obligated to  fund a  maximum of  approximately $125
million of the class  action settlement, exclusive of  expenses, with a  maximum
payment of less than $18 million in any single year; of the total amount of U.S.
Gypsum's obligation, all but approximately $13 million or less is expected to be
paid by U.S. Gypsum's insurance carriers.

    During  1992, approximately 20,100 Personal  Injury Cases were filed against
U.S. Gypsum  and approximately  10,600 were  settled or  dismissed. U.S.  Gypsum
incurred expenses of $21.6 million in 1992 with respect to Personal Injury Cases
of which $21.5 million was paid by insurance. In the period of January 1 through
May  6, 1993, approximately 8,700 Personal  Injury Cases were filed against U.S.
Gypsum and

                             (PREDECESSOR COMPANY)
                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
approximately 5,300 were settled or dismissed. U.S. Gypsum incurred expenses  of
$10.9 million in the period with respect to Personal Injury Cases of which $10.8
million was paid by insurance. As of May 6, 1993, December 31, 1992 and December
31,  1991, approximately  58,000, 54,000 and  43,000 Personal  Injury Cases were
outstanding against U.S. Gypsum, respectively.

    As of May 6, 1993, U.S. Gypsum's average settlement cost for Personal Injury
Cases over the past three years was approximately $1,350 per claim, exclusive of
defense costs.  Management  anticipated that  its  average settlement  cost  was
likely  to  increase due  to  such factors  as  the possible  insolvency  of co-
defendants, although  this increase  might be  offset to  some extent  by  other
factors,  including the  possibility for block  settlements of  large numbers of
cases and the apparent  increase in the percentage  of asbestos personal  injury
cases that appear to have been brought by individuals with little or no physical
impairment.   In  management's  opinion,  based  primarily  upon  U.S.  Gypsum's
experience  in  the  Personal   Injury  Cases  disposed   of  and  taking   into
consideration  a number of uncertainties,  it was probable that asbestos-related
Personal Injury Cases pending against U.S. Gypsum as of December 31, 1992, could
have been disposed of for an amount estimated to be between $80 million and $100
million, including  both  indemnity  costs  and legal  fees  and  expenses.  The
estimated  cost  of resolving  pending claims  takes  into account,  among other
factors, (i) an increase in the  number of pending claims; (ii) the  settlements
of  certain  large  blocks of  claims  for  higher per-case  averages  than have
historically been paid; and (iii) a slight increase in U.S. Gypsum's  historical
settlement average. No accrual was recorded for this amount because, pursuant to
the Wellington Agreement, U.S. Gypsum's Supporting Insurers are obligated to pay
these costs.

    Assuming  that the  Georgine class  action settlement  referred to  above is
approved substantially  in  its current  form,  management estimated,  based  on
assumptions  supplied by the Center, U.S.  Gypsum's maximum total exposure as of
May 6, 1993 in Personal Injury Cases during the next ten years (the initial term
of the agreement), including  liability for pending  claims, claims resolved  as
part  of the  class action settlement,  and opt  out claims, as  well as defense
costs and other expenses, at approximately $271 million, of which at least  $254
million  was expected to be paid by insurance. U.S. Gypsum's additional exposure
for claims filed by persons who have  opted out of Georgine would depend on  the
number of such claims that are filed, which could not be determined.

COVERAGE ACTION

    As  indicated above, all of U.S. Gypsum's carriers initially denied coverage
for the Property  Damage Cases and  the Personal Injury  Cases, and U.S.  Gypsum
initiated  the Coverage  Action to  establish its  right to  such coverage. U.S.
Gypsum has voluntarily dismissed the Supporting Insurers referred to above  from
the personal injury portion of the Coverage Action because they are committed to
providing  personal injury coverage in accordance with the Wellington Agreement.
U.S. Gypsum's  claims  against  the  remaining carriers  for  coverage  for  the
Personal Injury Cases have been stayed since 1984.

    On  January 7,  1991, the trial  court in  the Coverage Action  ruled on the
applicability of U.S. Gypsum's insurance policies to settlements and one adverse
judgment in eight Property  Damage Cases. The court  ruled that the eight  cases
were  generally covered, and  imposed coverage obligations  on particular policy
years based upon the dates when the presence of asbestos-containing material was
"first  discovered"  by  the   plaintiff  in  each   case.  The  court   awarded
reimbursement  of approximately $6.2 million spent by U.S. Gypsum to resolve the
eight cases. U.S. Gypsum appealed the court's ruling with respect to the  policy
years available to cover particular claims, and the carriers appealed most other
aspects of the court's ruling.

    U.S.  Gypsum's experience in the Property  Damage Cases suggests that "first
discovery" dates in the  eight cases referred to  above (1978 through 1985)  are
likely  to  be typical  of  most pending  cases.  U.S. Gypsum's  total insurance
coverage for  the years  1978  through 1984  totals approximately  $350  million
(after  subtracting  insolvencies  and discounts  given  to  settling carriers).
However, some pending cases, as well as  some cases filed in the future, may  be
found   to  have  first  discovery  dates  later  than  August  1,  1984,  after

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
which  U.S.  Gypsum's   insurance  policies   did  not   provide  coverage   for
asbestos-related claims. In addition, as described below, the first layer excess
carrier  for the  years 1980 through  1984 is  insolvent and U.S.  Gypsum may be
required to pay amounts otherwise covered by those and other insolvent policies.
Accordingly, if  the court's  ruling is  affirmed, U.S.  Gypsum will  likely  be
required to bear a portion of the cost of the property damage litigation.

    Eight  carriers,  including two  of  the Supporting  Insurers,  settled U.S.
Gypsum's claims for both property damage  and personal injury coverage and  were
dismissed  from the Coverage  Action entirely. Four of  these carriers agreed to
pay all or a substantial portion of their policy limits to U.S. Gypsum beginning
in 1991 and continuing  over the next four  years. Three other excess  carriers,
including  the two settling Supporting Insurers,  agreed to provide coverage for
the Property  Damage Cases  and the  Personal Injury  Cases subject  to  certain
limitations  and conditions, when and if  underlying primary and excess coverage
is exhausted. It  cannot presently  be determined  when such  coverage might  be
reached.  Taking into account the  above settlements, including participation of
certain of the settling  carriers in the  Wellington Agreement, and  consumption
through  December  31, 1992,  carriers providing  a  total of  approximately $97
million of unexhausted insurance had agreed, subject to the terms of the various
settlement agreements, to cover both  Personal Injury Cases and Property  Damage
Cases.  Carriers  providing  an additional  $276  million of  coverage  that was
unexhausted as of December  31, 1992 had agreed  to cover Personal Injury  Cases
under  the Wellington Agreement, but continued  to contest coverage for Property
Damage Cases and remained  defendants in the Coverage  Action. U.S. Gypsum  will
continue  to seek negotiated resolutions with  its carriers in order to minimize
the expense and delays of litigation.

    As of May 6, 1993, insolvency  proceedings had been instituted against  four
of  U.S.  Gypsum's  insurance  carriers.  Midland  Insurance  Company,  declared
insolvent in 1986, provided  excess insurance ($4 million  excess of $1  million
excess  of  $500,000 primary  in each  policy  year) from  February 15,  1975 to
February 15,  1978;  Transit  Casualty  Company,  declared  insolvent  in  1985,
provided  excess insurance  ($15 million  excess of  $1 million  primary in each
policy year)  from August  1, 1980  to December  31, 1985;  Integrity  Insurance
Company,  declared  insolvent in  1986, provided  excess insurance  ($10 million
quota share of $25 million  excess of $90 million) from  August 1, 1983 to  July
31,  1984; and  American Mutual Insurance  Company, declared  insolvent in 1989,
provided the primary  layer of insurance  ($500,000 per year)  from February  1,
1963  to April 15, 1971. It is possible that U.S. Gypsum will be required to pay
a presently indeterminable portion of the  costs that would otherwise have  been
covered by these policies.

    It  is not  possible to predict  the number of  additional lawsuits alleging
asbestos-related claims that  may be filed  against U.S. Gypsum.  The number  of
Personal  Injury Claims pending against U.S. Gypsum has increased in each of the
last several years.  In addition,  many Property Damage  Cases are  still at  an
early  stage and the potential liability therefrom is consequently uncertain. In
view of  the limited  insurance  funding currently  available for  the  Property
Damage  Cases  resulting  from the  continued  resistance  by a  number  of U.S.
Gypsum's insurers to providing coverage,  the effect of the asbestos  litigation
on  the Corporation will depend upon a variety of factors, including the damages
sought in the Property Damage Cases that reach trial prior to the completion  of
the Coverage Action, U.S. Gypsum's ability to successfully defend or settle such
cases,  and the  resolution of the  Coverage Action. As  a result, as  of May 6,
1993, management  was unable  to determine  whether an  adverse outcome  in  the
asbestos  litigation  would have  a material  adverse effect  on the  results of
operations or the consolidated financial position of the Corporation.

ENVIRONMENTAL LITIGATION

    The Corporation and certain of its  subsidiaries had 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 substantially all of these sites, the involvement
of  the  Corporation  or  its  subsidiaries  is  expected  to  be  minimal.  The
Corporation believes that

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
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  estimable   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.

INDUSTRY AND GEOGRAPHIC SEGMENTS

    Transactions between geographic areas are accounted for on an "arm's-length"
basis. No single customer  accounted for 4% or  more of consolidated net  sales.
Export  sales  to  foreign unaffiliated  customers  represent less  than  10% of
consolidated net sales.

    Intrasegment and  intersegment  eliminations  largely  reflect  intercompany
sales.  Segment operating profit/(loss) includes all costs and expenses directly
related to the segment involved and an allocation of expenses which benefit more
than one segment.

    Variations in the levels of corporate identifiable assets primarily  reflect
fluctuations  in the levels of cash and cash equivalents. Restricted cash of $88
million, which represents the proceeds from the 1991 sale of DAP Inc.,  formerly
a  wholly  owned  subsidiary  of  the  Corporation,  is  included  in  corporate
identifiable assets for 1992. Information shown in the following tables has been
restated to conform to the Corporation's current industry segment organization.

SUBSIDIARY DEBT GUARANTEES

    As of May 6,  1993, $340 million aggregate  principal amount of Senior  2002
Notes  were  outstanding.  Each  of  U.S.  Gypsum,  USG  Industries,  Inc.,  USG
Interiors, USG Foreign Investments, Ltd., L&W Supply, Westbank Planting Company,
USG Interiors International,  Inc., American  Metals Corporation  and La  Mirada
Products  Co.,  Inc. (together,  the "Combined  Guarantors") guaranteed,  in the
manner described below, both the obligations of the Corporation under the Credit
Agreement and the Senior 2002 Notes. The Combined

                             (PREDECESSOR COMPANY)
                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
Guarantors  are  jointly  and  severally  liable  under  these  guarantees  (the
"Subsidiary  Guarantees").  Holders  of the  Bank  Debt  have the  right  to (i)
determine whether,  when and  to what  extent the  guarantees will  be  enforced
(provided  that each  guarantee payment  will be  applied to  the Bank  Debt and
Senior 2002 Notes  pro rata based  on the respective  amounts owed thereon)  and
(ii)  amend or eliminate the guarantees.  The guarantees will terminate when the
Bank Debt is retired regardless of whether any Senior 2002 Notes remain  unpaid.
The  liability of each of the Combined Guarantors on its guarantee is limited to
the greater of (i)  95% of the  lowest amount, calculated as  of July 13,  1988,
sufficient   to  render  the  guarantor  insolvent,  leave  the  guarantor  with
unreasonably small capital  or leave the  guarantor unable to  pay its debts  as
they become due (each as defined under applicable law) and (ii) the same amount,
calculated  as of the date any demand  for payment under such guarantee is made,
in each case plus collection costs. The guarantees are senior obligations of the
applicable guarantor and rank PARI PASSU with all unsubordinated obligations  of
the guarantor.

    Subsidiaries   other   than   the   Combined   Guarantors   (the   "Combined
Non-Guarantors"), substantially  all of  which are  subsidiaries of  Guarantors,
primarily  included, as of May 6,  1993, CGC, Gypsum Transportation Limited, USG
Canadian Mining  Ltd.  and  the  Corporation's  Mexican,  European  and  Pacific
subsidiaries.  The long-term debt of the  Combined Non-Guarantors of $28 million
as of May 6, 1993 has  restrictive covenants that restrict, among other  things,
the payment of dividends.

    The following condensed consolidating information presents:

(i)   Condensed  financial statements as  of May 6,  1993 and for  the period of
    January 1 through May 6, 1993, and the year ended December 31, 1992: (a) the
    Corporation on a parent company only basis (the "Parent Company," which  was
    the  only entity of the Corporation  included in the bankruptcy proceeding);
    (b) the Combined Guarantors;  (c) the Combined  Non-Guarantors; and (d)  the
    Corporation   on  a  consolidated  basis.   Due  to  the  Restructuring  and
    implementation of fresh start accounting,  the financial statements for  the
    restructured company (periods after May 6, 1993) are not comparable to those
    of  the predecessor  company. Except  for the  following condensed financial
    statements, separate  financial information  with  respect to  the  Combined
    Guarantors  is omitted as such separate  financial information is not deemed
    material to investors.

(ii) The Parent Company and Combined Guarantors shown with their investments  in
    their subsidiaries accounted for on the equity method.

(iii)  Elimination entries necessary  to consolidate the  Parent Company and its
    subsidiaries.

                                USG CORPORATION
                               MANAGEMENT REPORT

    Management is responsible for the preparation and integrity of the financial
statements  and  related  notes  included  herein.  These  statements  have been
prepared in accordance  with generally  accepted accounting  principles and,  of
necessity,  include some amounts  that are based  on management's best estimates
and judgments.

    The Corporation's accounting systems  include internal controls designed  to
provide reasonable assurance of the reliability of its financial records and the
proper  safeguarding  and  use  of  its  assets.  Such  controls  are  based  on
established policies and procedures, are  implemented by trained personnel,  and
are  monitored through an internal audit program. The Corporation's policies and
procedures prescribe that the Corporation  and its subsidiaries are to  maintain
ethical  standards and  that its  business practices  are to  be consistent with
those standards.

    The Audit Committee of the Board, consisting solely of outside Directors  of
the  Corporation, maintains an ongoing appraisal, on behalf of the stockholders,
of the effectiveness of the independent auditors and management with respect  to
the  preparation of financial statements, the  adequacy of internal controls and
the Corporation's accounting policies.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Stockholders and Board
  of Directors of USG Corporation:

We have audited the accompanying  consolidated balance sheet of USG  Corporation
(Predecessor  Company), a  Delaware corporation, and  subsidiaries as  of May 6,
1993 and the related consolidated statements of earnings and cash flows for  the
period  of January  1 through May  6, 1993 and  for the year  ended December 31,
1992. 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.

As discussed in Notes to Financial Statements -- "Financial Restructuring" note,
on  May  6,   1993,  the   Corporation  completed   a  comprehensive   financial
restructuring through the implementation of a prepackaged plan of reorganization
under  Chapter 11 of the  United States Bankruptcy Code  and applied fresh start
accounting. The restructuring resulted in an extraordinary gain of $944 million,
primarily from the exchange  of debt, and fresh  start accounting resulted in  a
$709  million gain, primarily  from revaluing assets  and liabilities to reflect
reorganization value. These one-time credits to  income were recorded as of  May
6,  1993 by the Predecessor Company. As  such, results of operations through May
6, 1993  (Predecessor Company)  are not  comparable with  results of  operations
subsequent to that date.

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 May  6, 1993 and  the results of  their operations and their
cash flows for  the period of  January 1 through  May 6, 1993  and for the  year
ended  December  31,  1992,  in conformity  with  generally  accepted accounting
principles.

As discussed in Notes to Financial  Statements -- "Litigation" note, in view  of
the  limited  insurance funding  currently available  for property  damage cases
resulting from the continued resistance by a number of U.S. Gypsum's insurers to
providing coverage, the  effect of  the asbestos litigation  on the  Corporation
will  depend upon a variety of factors, including the damages sought in property
damage cases that reach  trial prior to the  completion of the coverage  action,
U.S.  Gypsum's  ability to  successfully defend  or settle  such cases,  and the
resolution of  the  coverage  action.  As a  result,  management  is  unable  to
determine  whether an  adverse outcome  in the  asbestos litigation  will have a
material adverse  effect  on  the  consolidated results  of  operations  or  the
consolidated financial position of the Corporation.

As  discussed in Notes to Financial  Statements -- "Cumulative Effect of Changes
in Accounting Principles" note, on January  1, 1993 the Corporation changed  its
method  of  accounting  for  postretirement  benefits  other  than  pensions and
accounting for income taxes.

- ------------------------
(a)  Due to the Restructuring and implementation of fresh start accounting,  the
     financial statements effective May 7, 1993 for the Restructured Company are
     not  comparable  to  financial  statements  prior  to  that  date  for  the
     Predecessor Company.

(b)  Fourth quarter 1994 gross profit, operating  profit and net loss reflect  a
     $30  million pre-tax  charge ($17 million  after-tax) to cost  of sales for
     asbestos litigation settlements. Fourth quarter 1994 net loss also reflects
     a $16 million pre-tax  charge ($9 million after-tax)  for the write-off  of
     reorganization debt discount.

(c)  Effective  May  7,  1993,  the  Corporation  began  amortizing  its  excess
     reorganization value which reduced operating profit and net earnings.  This
     non-cash amortization amounted to $42 million, $42 million, $43 million and
     $42 million in the first through fourth quarters of 1994, respectively. For
     the  period of May 7  through June 30 and the  third and fourth quarters of
     1993, amortization of excess reorganization value amounted to $28  million,
     $43 million and $42 million, respectively.

(d)  As  a result of common shares issued in  the first quarter of 1994, the sum
     of the losses per  common share for  the four quarters  of 1994, which  are
     based on average shares outstanding during each quarter, does not equal the
     loss  per common share for the year ended December 31, 1994, which is based
     on the average shares outstanding during the year.

(e)  Stock price ranges  are for  transactions on  the New  York Stock  Exchange
     (trading  symbol USG), which is the  principal market for these securities.
     Stockholders of record as of January  31, 1995: Common -- 6,072;  Preferred
     -- none.

(f)  First  quarter 1993  net loss reflects  a one-time after-tax  net charge of
     $150 million for the cumulative effect of changes in accounting  principles
     and  a pre-tax reorganization items expense of $69 million. Net earnings in
     the period  of April  1 through  May  6, 1993  include a  one-time  pre-tax
     reorganization  items  gain  of  $778  million  and  a  one-time  after-tax
     extraordinary gain of $944 million, both of which were associated with  the
     Restructuring. Net loss in the fourth quarter of 1993 includes an after-tax
     extraordinary  loss of $21 million related to the Corporation's 1994 Equity
     Offering and Note Placement.

(g)  Per-share information for periods prior to May 7, 1993 is omitted  because,
     due  to the Restructuring and implementation  of fresh start accounting, it
     is not meaningful.
