  % SENIOR NOTES DUE 2005

   
The   %  Senior Notes due 2005  (the "Notes") of USG  Corporation ("USG" or  the
"Corporation")  will mature on             , 2005. Interest on the Notes will be
payable semi-annually on              and               of each year,  beginning
           , 1996. The Notes are redeemable at the option of the Corporation, in
whole  or in part at any time  on or after              , 2000 at the redemption
prices set forth herein plus accrued interest.
    

   
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 will be  incurred under a new  credit agreement (the "New  Credit
Agreement") to be entered into by the Corporation and certain banks prior to the
closing  of  this  offering.  Borrowings under  the  New  Credit  Agreement and,
pursuant to  negative pledge  clauses,  the Notes  and substantially  all  other
public  indebtedness of the Corporation will  share in security interests in the
capital stock  of  certain of  the  Corporation's domestic  subsidiaries  to  be
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
Control or (ii)  if the Corporation  reaches Investment Grade  Status, upon  the
occurrence  of  both  a Designated  Event  and  a Rating  Decline  in connection
therewith. See "Description of Notes."
    

Application will be made to list the Notes on the New York Stock Exchange.

                                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
of the  Corporation's existing  bank credit  facility with  a seven  year,  $500
million  bank revolving credit  facility under a new  credit agreement (the "New
Credit Agreement"). The Corporation intends to use approximately $192 million of
borrowings under  the New  Credit Agreement  to repay  all borrowings  currently
outstanding  under its  existing 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 be secured by first priority 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
will  primarily control the operation of  the Collateral Trust. See "Description
of Collateral Trust."

Principal Covenants..........................  The Indenture will contain certain  covenants
                                               which restrict the ability of the Corporation
                                               to  pay  dividends  and  make  certain  other
                                               distributions in respect of its capital stock
                                               and the ability  of the  Corporation and  its

                                               things, incur additional indebtedness, create
                                               secured debt, enter into  or permit sale  and

                                               assets,   and    enter    into    contractual
                                               restrictions  on  the  ability  of Restricted
                                               Subsidiaries to pay dividends or make certain
                                               other  distributions.   If  the   Corporation
                                               reaches    Investment   Grade   Status,   the
                                               foregoing principal covenants  will cease  to
                                               be operative, except for those covenants that
                                               restrict   incurrence  of  indebtedness,  the
                                               creation of secured debt, sale and  leaseback
                                               transactions,   and,  with   respect  to  the
                                               Corporation, mergers  and  sales  of  all  or
                                               substantially all of its assets. However, all
                                               of these restrictions are subject to a number
                                               of important qualifications. See "Description

                                               Holders  of  the  Bank  Debt  will  primarily

                                               The  rights  of   the  Corporation  and   its
                                               creditors, including holders of the Notes, to
                                               realize  upon the 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 $1,027 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."

(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.

(c)  Amortization  of Excess Reorganization  Value (as defined  herein and shown
     separately above) and amortization of 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  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.

                                  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  $1,027 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 are 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 $1,027  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 will be 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 will 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 will  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 Agreement."

CERTAIN TRADING CONSIDERATIONS

    There is currently no trading market for the Notes. Although the Corporation
intends  to cause the Notes  to be authorized for listing  on the New York Stock
Exchange, there can  be no assurance,  even if such  authorization is  obtained,
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.

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 virtually 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.  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
of the  Corporation's existing  bank credit  facility with  a seven  year,  $500
million  bank  revolving credit  facility under  the  New Credit  Agreement. The
Corporation intends to use  approximately $192 million  of borrowings under  the
New  Credit Agreement  to repay all  borrowings currently  outstanding under its
existing  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 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  be secured by  first priority 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 will primarily control
the operation of the Collateral Trust. See "Description of Collateral Trust."
    

   
    The New Credit Agreement will be a seven year, $500 million revolving credit
facility which will mature in 2002. The New Credit Agreement will bear  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 existing credit agreement bear interest at  a
rate of LIBOR plus 1.875%. The New Credit Agreement will be 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.

(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.

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.

    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.

</TABLE>

    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.

                                       20

    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

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 its 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:

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   executed  a   commitment  letter   (the  "Financing
Commitment") with Chemical Securities Inc.  ("CSI"), under which CSI has  agreed
to  use  its best  efforts  to arrange  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") selected by the Corporation and CSI. Chemical
Bank ("Chemical")  will  serve as  sole  and exclusive  agent.  The  Corporation
expects  to enter  into the New  Credit Agreement  prior to the  closing of this
offering.
    

   
    A copy of the  form of 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  will consist 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
will expire 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 will be 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") will be provided under the New Credit Agreement on an uncommitted
basis through  a competitive  auction  mechanism. The  Corporation will  not  be
obliged  to accept any bids  submitted. The Corporation will  have the option of
inviting the Banks to submit bids (via Chemical) for advances ("Competitive  Bid
Loans"). Bidding will 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.
    

                                       36
<PAGE>
   
    "Alternate  Base  Rate"  will  be  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 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" will be 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 ponts  (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  will be  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 will contain 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  will  contain
certain  exceptions  to  the  restrictions imposed  upon  the  operation  of the
Corporation's business.
    

FINANCIAL COVENANTS

   
    The New Credit Agreement will contain 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, will  mean, 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

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, 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

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.
    

   
    "EBITDA" for any period, will mean the consolidated operating earnings  from
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" will mean  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 will mean 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 will contain 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,

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.
    

GENERAL

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

                                       38
<PAGE>
   
payable semi-annually on              and             of  each year,  commencing
         ,  1996, to the persons in whose  names the Notes are registered at the
close of business on the next preceding           or          , as the case  may
be. Interest on the Notes shall accrue from          , 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  will be incurred  under the New
Credit Agreement to be entered into  by the Corporation and certain banks  prior
to  the closing of this offering. 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        ,
2000. Thereafter, the Notes may, from time to time, be redeemed, in whole or  in
part,  at the option of the  Corporation upon not less than  30 nor more than 60
days' prior  notice  to  Holders,  at the  redemption  prices  set  forth  below
(expressed  in percentages  of the principal  amount thereof),  plus accrued and
unpaid interest thereon, up to the Redemption Date.

</TABLE>

    If less than all of the Notes are to be redeemed, the selection of the Notes
to be redeemed shall be made as provided in the Indenture.

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.
    

                                       39
<PAGE>
   
    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;  and  (iv) a
description of  the  transaction  or transactions  constituting  the  Change  of
Control  and 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  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
    

                                       40
<PAGE>
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 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
    

                                       41
<PAGE>
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  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

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

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

(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

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

    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

Restricted  Subsidiary of the  Corporation); (iii) Indebtedness  of a Restricted
Subsidiary in  respect  of Capital  Lease  Obligations and  Sale  and  Leaseback

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

    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  the
"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

                                       43
<PAGE>
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
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 and has a
Stated Maturity later than the Stated Maturity of the Notes as the  Indebtedness
so refinanced 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

                                       44
<PAGE>
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  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 in which the Receivables Subsidiary has an
investment 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
    

                                       45
<PAGE>
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) certain transactions with an
officer or director  of the  Corporation or  any Subsidiary  of the  Corporation
entered  into  in the  ordinary course  of  business (including  compensation or
employee benefit arrangements with any officer or director of the Corporation or
any Subsidiary of the Corporation) or (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, 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

                                       46
<PAGE>
   
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 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
    

                                       47
<PAGE>
(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  or  the  merger  or   consolidation  of  two  or  more   Restricted
Subsidiaries of 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 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, upon redemption 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

                                       48
<PAGE>
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 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.

Person  or group that is beneficial owner of  50% or less of the Voting Stock of
the Corporation  is  able to  elect  a majority  of  the Board  pursuant  to  an

secured by any Lien on any property or asset of such Person (whether or not such
obligation  is  assumed by  such Person),  the amount  of such  obligation being
deemed to be the lesser of the value of such property or asset or the amount  of
the  obligations so secured. Notwithstanding  the foregoing, the following shall
not  constitute  Indebtedness:  (w)  obligations  Incurred  in  connection  with
currency  hedges  and  energy hedges  entered  into  in the  ordinary  course of
business and (x)  Indebtedness of any  Person existing at  the time such  Person

in each case in an  amount sufficient to pay all  the principal of (and  premium
on, if any) and interest on such Indebtedness on the dates such payments are due

Stock were repurchased on any date on which Indebtedness shall be required to be
determined   pursuant  to  this  Indenture;  provided,  however,  that  if  such
Redeemable Stock is not then permitted  to be repurchased, the repurchase  price
shall  be the book  value of such  Redeemable Stock. The  amount of Indebtedness
arising from any Guarantee shall be limited  to the lesser of (y) the amount  of
Indebtedness  underlying such  Guarantee or (z)  the limit, if  any, on recovery
against the Guarantor contained in such Guarantee. The amount of Indebtedness of
any Person at  any date shall  be the outstanding  balance at such  date of  all
unconditional  obligations as described  above and the  maximum liability of any
contingent obligations as described above at such date.

its  Restricted  Subsidiaries  from  escrow,  and  provided  that  any  non-cash
consideration received in connection with an Asset Sale, which is within 90 days

Trust  Agreement, the  Grantors will  grant 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").

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 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.

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.

                   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."

                             (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)

                                  (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

 (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
    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 as of March 31, 1995 and December 31,
    1994,  has  restrictive covenants  that  restrict, among  other  things, the
    payment of dividends.

    The following condensed consolidating information presents:

    (i)  Condensed financial statements as  of March 31,  1995 and December  31,
         1994  and for the three months ended March 31, 1995 and 1994 of (a) the
         Corporation  on  a  parent  company   only  basis,  (b)  the   Combined
         Guarantors,  (c) the Combined Non-Guarantors and (d) the Corporation on
         a consolidated  basis. Except  for  the following  condensed  financial
         statements, separate financial information with respect to the Combined
         Guarantors is not deemed material to investors and is omitted.)

    (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.

                             (RESTRUCTURED COMPANY)
                         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.

</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
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

    The LIFO value  of U.S.  domestic inventories under  fresh start  accounting
exceeded  that computed for U.S. Federal income  tax purposes by $30 million and
$25 million as of December 31, 1994 and 1993, respectively.

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 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

                             (RESTRUCTURED COMPANY)
                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
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
currently

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
maturing long-term debt as  of December 31,  1994 and paid  in January 1995.  In
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

through December 31, 1993. Net pension expense included the following components

    The projected  benefit  obligation  in  excess of  assets  consisted  of  an
unrecognized  net  loss  in  each  period  due  to  changes  in  assumptions and
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.

    The  assumed health care  cost trend rate used  in measuring the accumulated
postretirement benefit obligation was  10% and 11% as  of December 31, 1994  and
1993,  respectively, with a gradually declining rate  to 5% 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 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
and the period  of May 7  through December 31,  1993, respectively. The  assumed
discount  rate  used  in  determining  the  accumulated  postretirement  benefit
obligation was 8.25% and 7% as of December 31, 1994 and 1993, respectively.

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):

                                USG CORPORATION
                             (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

                                      F-32
<PAGE>

                             (RESTRUCTURED COMPANY)
                   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

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.

                             (RESTRUCTURED COMPANY)
                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

SUBSIDIARY DEBT GUARANTEES

    The Corporation had $298 million and $478 million aggregate principal amount
of Senior 2002 Notes outstanding as of December 31, 1994 and 1993, respectively.
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 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 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.

                         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.  For  the
period  of January  1 through  May 6,  1993, net  currency translation  gains or
losses on foreign subsidiaries are included in deferred currency translation,  a
component of stockholders' equity. For the year ended December 31, 1992, Mexican
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):

    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):

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 follows (dollars in millions):

</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

    For the period of January 1 through May 6, 1993, the expected long-term rate
of return on plan assets was 9%, the assumed weighted average discount rate used
in determining  the  accumulated benefit  obligation  was  8% and  the  rate  of
increases in projected future compensation levels was 5.5%.

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.

                             (PREDECESSOR COMPANY)
                   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

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

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

                             (PREDECESSOR COMPANY)
                   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

                                USG CORPORATION
                             (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

                                USG CORPORATION
                             (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.

                               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

(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

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

    Section  145 of  the Delaware  General Corporation  Law ("Section  145") (a)
gives Delaware corporations broad powers  to indemnify their present and  former
directors  and officers  and those  of affiliated  corporations against expenses
incurred in the defense of any lawsuit to which they are made parties by  reason
of  being  or  having been  such  directors  or officers,  subject  to specified
conditions and  exclusions, (b)  gives a  director or  officer who  successfully
defends  an  action  the right  to  be  so indemnified  and  (c)  authorizes the
corporation  to  buy   directors'  and  officers'   liability  insurance.   Such
indemnification  is not exclusive of any  other right to which those indemnified
may be entitled under any bylaw, agreement, vote of stockholders or otherwise.

    A bylaw provides that the Corporation  (a) shall indemnify every person  who
is  or was a director or officer of the  Corporation or is or was serving at the
Corporation's  request  as  a  director  or  officer  of  another   corporation,
partnership,  joint venture,  trust or  other enterprise  and (b)  shall, if the
board of directors so directs, indemnify any person who is or was an employee or
agent of the Corporation or is or was serving at the Corporation's request as an
employee or agent of another  corporation, partnership, joint venture, trust  or
other  enterprise, to the extent, in the  manner, and subject to compliance with
the applicable standards of conduct, provided by Section 145 as the same (or any
substitute provision therefor) may be in effect from time to time.

    Any such indemnification shall continue as to a person who has ceased to  be
a  director, officer, employee  or agent and  shall inure to  the benefit of the
heirs, executors and administrators of such a person.

    The Corporation  has procured  insurance for  the purpose  of  substantially
covering its future potential liability for indemnification under Section 145 as
discussed above and certain future potential liability of individual officers or
directors   incurred  in  their  capacity  as  such  which  is  not  subject  to
indemnification.

    The Corporation has entered into Indemnification Agreements with each of its
officers  and  directors.  The  Indemnification  Agreements  provide  that   the
Corporation  shall indemnify and keep indemnified  the indemnitee to the fullest
extent authorized by Section 145 as it may  be in effect from time to time  from
and  against any expenses  (including expenses of  investigation and preparation
and reasonable fees and  disbursements of legal  counsel, accountants and  other
experts),  judgments, fines and amounts paid  in settlement by the indemnitee in
connection with any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative, and whether or not the
cause of action, suit  or proceeding incurred  before or after  the date of  the
Indemnification  Agreement. The  Indemnification Agreements  further provide for
advancement of amounts to cover expenses incurred by the indemnitee in defending
any such action, suit or proceeding subject to an undertaking by the  indemnitee
to  repay any expenses advanced  which it is later determined  he or she was not
entitled to receive.

ITEM 16.  EXHIBITS AND FINANCIAL STATEMENT SCHEDULES

    (a) The following is  a complete list  of Exhibits filed as  a part of  this
       Registration Statement:

    See Exhibit Index

ITEM 17.  UNDERTAKINGS

    The Registrant hereby undertakes:

   
        (1)_For  purposes  of  determining  any  liability  under  the  Act, the
    information omitted from  the form  of prospectus filed  as a  part of  this
    registration statement in reliance upon Rule 430A and contained in a form of
    prospectus  filed by  the registrant  pursuant to  Rule 424(b)(1)  or (4) or
    497(h) under  the  Act shall  be  deemed to  be  part of  this  registration
    statement as of the time it was declared effective.
    

   
        (2)  That,  for  the  purpose of  determining  any  liability  under the
    Securities Act of 1933, each  such post-effective amendment shall be  deemed
    to  be  a  new registration  statement  relating to  the  securities offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial bona fide offering thereof.
    

   
        (3) To remove from registration  by means of a post-effective  amendment
    any   of  the  securities  being  registered  which  remain  unsold  at  the
    termination of the offering.
    

   
        (4) That, for purposes of determining any liability under the Securities
    Act of  1933, each  filing of  the registrant's  annual report  pursuant  to
    section  13(a) or section 15(d) of the Securities Exchange Act of 1934 (and,
    where applicable, each filing  of an employee  benefit plan's annual  report
    pursuant  to  section 15(d)  of  the Securities  Exchange  of 1934)  that is
    incorporated by reference in the  registration statement shall be deemed  to
    be  a new registration statement relating to the securities offered therein,
    and the offering of such securities at  that time shall be the initial  bona
    fide offering thereof.
    

   
        (5)  Insofar  as  indemnification  for  liabilities  arising  under  the
    Securities Act  may  be permitted  to  directors, officers  and  controlling
    persons  of the Company pursuant to  the foregoing provisions, or otherwise,
    the Company  has been  advised that  in the  opinion of  the Securities  and
    Exchange  Commission  such  indemnification  is  against  public  policy  as
    expressed in the  Securities Act  and is, therefore,  unenforceable. In  the
    event  that a claim for indemnification against such liabilities (other than
    the payment  by the  Company of  expenses incurred  or paid  by a  director,
    officer  or controlling person  of the Company in  the successful defense of
    any action, suit  or proceeding) is  asserted by such  director, officer  or
    controlling  person in connection with  the securities being registered, the
    Company will,  unless in  the opinion  of its  counsel the  matter has  been
    settled   by  controlling  precedent,  submit  to  a  court  of  appropriate
    jurisdiction the question of whether  such indemnification by it is  against
    public policy as expressed in the Securities Act and will be governed by the
    final adjudication of such issue.

     the Securities Act of 1933 (the "Act") and has filed with the Securities
     and Exchange Commission (the "Commission") a registration statement (file
     number 33-  ) on such Form, including a related preliminary prospectus, for
     the registration under the Act of the offering and sale of the Securities.
     The Company may have filed one or more amendments thereto, including the
     related preliminary prospectus, each of which has previously been furnished
     to you.  The Company will next file with the Commission one of the
     following:  (i) prior to effectiveness of such registration statement, a
     further amendment to such registration statement, including the form of
     final prospectus, or (ii) after the effectiveness of such registration
     statement, a final prospectus in accordance with Rules  430A and 424(b)(1)
     or (4).  In the case of clause (ii), the Company has included in such
     registration statement, as amended at the Effective Date, all information
     (other than Rule 430A Information) required by the Act and the rules
     thereunder to be included in the Prospectus with respect to the Securities
     and the offering thereof.  As filed, such amendment and form of final pro-
     spectus, or such final prospectus, shall contain all Rule 430A Information,
     together with all other such required information, with respect to the
     Securities and the offering thereof and, except to the extent the
     Underwriters shall agree in writing to a modification, shall be in all
     substantive respects in the form furnished to you prior to the Execution
     Time or, to the extent not completed at the Execution Time, shall contain
     only such specific additional information and other changes (beyond that
     contained in the latest Preliminary Prospectus) as the Company has advised
     you, prior to the Execution Time, will be included or made therein.

          (b)  On the Effective Date, the Registration Statement did or will,
     and when the Prospectus is first filed (if required) in accordance with
     Rule 424(b) and on the Closing Date (as defined in Section 3 hereof), the
     Prospectus (and any supplements thereto) will, comply in all material
     respects with the applicable requirements of the Act, the Securities
     Exchange Act of 1934 (the "Exchange Act") and the Trust Indenture Act of
     1939 (the "Trust Indenture Act") and the respective rules thereunder; on
     the Effective Date, the Registration Statement did not or will not contain
     any untrue statement of a material fact or omit to state any material fact
     required to be stated therein or necessary in order to make the statements
     therein not misleading; on the Effective Date and on the Closing Date the
     Indenture did or will comply in all material respects with the requirements
     of the Trust Indenture Act and the rules thereunder; and, on the Effective
     Date, the Prospectus, if not filed pursuant to Rule 424(b), did not or will
     not, and on the date of any filing pursuant to Rule 424(b) and on the
     Closing Date, the Prospectus (together with any supplement thereto) will
     not, include any untrue statement of a material fact or omit to state a
     material fact necessary in order to make the statements therein, in the
     light of the circumstances under which they were made, not misleading;
     PROVIDED, HOWEVER, that the Company makes no representations or warranties
     as to (i) that part of the Registration Statement which shall constitute
     the Statement of Eligibility and Qualification (Form T-1) under the Trust
     Indenture Act of  the Trustee or (ii) the information contained in or omit-
     ted from the Registration Statement or the Prospectus (or any supplement
     thereto) in reliance upon and in conformity with information furnished in
     writing to the Company by or on behalf of any Underwriter through the
     Underwriters specifically for inclusion in the Registration Statement or
     the Prospectus (or any supplement thereto).

          (c)  Each of the Company and its subsidiaries is a corporation duly
     organized, validly existing and in good standing under the laws of the
     jurisdiction of its incorporation; all of the issued shares of capital
     stock of each subsidiary have been duly and validly authorized and issued,
     are fully paid and nonassessable, and (except for directors' qualifying
     shares and those shares not held by the Company or any of its Affiliates)
     are owned


                                        2

<PAGE>

     directly or indirectly by the Corporation, free and clear of all liens,
     encumbrances, equities or claims, except for the shares of capital stock of
     USG Interiors (Europe) SA, CGC and except as provided under the Collateral
     Trust Agreement (as such term is defined in the Prospectus).  Each of the
     Company and its subsidiaries has the requisite corporate power and
     authority to own or lease and operate its properties and to carry on its
     business as described in the Prospectus except where the failure to have
     such power and authority would not reasonably be expected to result in a
     material adverse change in the financial condition, assets or operations of
     the Company and its subsidiaries taken as a whole (a "MAC").  The Company
     has the requisite power and authority to authorize the offering of the Se-
     curities to be sold by it, and to issue, sell and deliver the Securities to
     be sold by it.  The Company has the requisite power and authority to enter
     into this Agreement and to perform its obligations hereunder.  It is under-
     stood and agreed that the Company will have to deliver good standing
     certificates and similar documentation only with respect to United States
     Gypsum Company, USG Interiors, Inc., L&W Supply Corporation,
     and USG Foreign Investments, Ltd. (individually a "Major
     Subsidiary" and collectively the "Major Subsidiaries").

          (d)  Each of the Company and its subsidiaries is duly qualified or
     licensed and in good standing as a foreign corporation duly authorized to
     do business in each jurisdiction in which it owns or leases properties, or
     conducts any business so as to require such qualification or licensure,
     except where the failure to be so qualified and authorized would not
     reasonably be expected to result in a MAC.

          (e)  Except as may be disclosed in the Registration Statement and the
     Prospectus (including the documents incorporated therein), there are no
     actions, proceedings or investigations pending or to the best of the
     Company's knowledge threatened (solely in the case of such actions,
     proceedings or investigations which would result in a MAC, in writing)
     which question the validity of this Agreement or any action taken or to be
     taken pursuant hereto or thereto which would result in a MAC, or which is
     required to be disclosed in the Registration Statement or Prospectus which
     is not adequately disclosed in the Registration Statement or Prospectus, as
     the case may be, and, to the Company's knowledge, there is no franchise,
     contract or other document required to be described in the Registration
     Statement or Prospectus, or required to be filed as an exhibit to the
     Registration Statement, which is not so described or filed.

          (f)  The Company and its subsidiaries are not in breach or violation
     of any term or provision of any agreement, instrument, judgment, decree,
     order, statute, rule or governmental regulation, domestic or foreign,
     applicable to the Company or its subsidiaries or to any of their respective
     properties or assets, which breach, breaches, violation or violations would
     reasonably be expected to individually or in the aggregate result in a MAC,
     and the Company and its subsidiaries are not in violation of any term of
     their respective charters or by-laws.  The compliance by the Company with
     all of the provisions of this Agreement, and the performance of the
     transactions contemplated by this Agreement will not result in any such
     violation or be in conflict with or constitute a default under any such
     term, which conflict or default would result in a MAC or result in the
     creation of any mortgage, lien, charge or encumbrance upon any of the
     properties or assets of the Company pursuant to any such term which would
     reasonably be expected to result in a MAC.  No consent, approval,
     authorization or order of any court or governmental agency or body is
     required for the consummation by the Company and the subsidiaries of the
     transactions contemplated herein, except such as have been obtained under
     the Act and such as may be required under the Blue Sky Laws of any
     jurisdiction in connection with the distribution of the Securities and such
     other approvals as have been obtained.

          (g)  Each of the Company and its subsidiaries has all certificates,
     consents, exemptions, orders, permits, licenses, authorizations, or other


                                        3

<PAGE>

     approvals (each, an "Authorization") of and from, and has made all declara-
     tions  and filings with, all Federal, state, local and other governmental
     authorities, all self-regulatory organizations and all courts and other
     tribunals, necessary or required to own, lease, license and use its
     properties and assets and to conduct its business in the manner described
     in the Prospectus, except to the extent that the failure to obtain or file
     any such Authorizations would not, singly or in the aggregate, reasonably
     be expected to result in a MAC.  All such Authorizations are in full force
     and effect with respect to the Company and subsidiaries, and the Company
     and its subsidiaries are in compliance in all material respects with the
     terms and conditions of all such Authorizations and with the rules and
     regulations of the regulatory authorities and governing bodies having
     jurisdiction with respect thereto other than such instances which singly or
     in the aggregate would not reasonably be expected to result in a MAC.

          (h)  The Company is not an "investment company" within the meaning of
     the Investment Company Act of 1940, as amended, nor is it subject to
     regulation under the Interstate Commerce Act or any federal or state
     statute or regulation limiting its ability to incur indebtedness for
     borrowed money.

          (i)  The Company has not taken, directly or indirectly, any action
     designed to cause or to result in, or that has constituted or which might
     reasonably be expected to constitute, the stabilization or manipulation of
     the price of any security of the Company to facilitate the sale or resale
     of the Securities.

          (j)  The Securities to be issued and sold by the Company to the
     Underwriters have been duly and validly authorized and, when issued and
     delivered against payment therefor as provided herein, will be duly and
     validly issued and fully paid and will conform in all material respects to
     the description of the Securities contained in the Prospectus.

          (k)  The Indenture has been duly authorized, executed and delivered,
     has been duly qualified under the Trust Indenture Act, and constitutes a
     legal, valid and binding instrument enforceable against the Company in
     accordance with its terms (subject, as to enforcement of remedies, to
     applicable bankruptcy, reorganization, insolvency, moratorium or other laws
     affecting creditors' rights generally from time to time in effect and to
     general principles of equity); and the Securities have been duly authorized
     and, when executed and authenticated in accordance with the  provisions of
     the Indenture and delivered to and paid for by the Underwriter pursuant to
     this Agreement, will constitute legal, valid and binding obligations of the
     Company entitled to the benefits of the Indenture.

          (l)  This Agreement has been duly authorized and validly executed and
     delivered by the Company and constitutes a valid and legally binding
     agreement of the Company, enforceable against the Company in accordance
     with its terms (assuming the due execution and delivery by the parties
     thereto other than the Company) subject to the effect of bankruptcy,
     insolvency, reorganization, arrangement, moratorium, fraudulent conveyance
     and other similar laws relating to or affecting the enforcement of rights
     of secured or unsecured creditors generally.

          (m)  None of the transactions contemplated by this Agreement or the
     Indenture (including, without limitation, the use of the proceeds from the
     sale of the Securities) will violate or result in a violation of Section 7
     of the Exchange Act, or any regulation promulgated thereunder, including,
     without limitation, Regulations G, T, U and X of the Board of Governors of
     the Federal Reserve System.

          2.   PURCHASE AND SALE.  Subject to the terms and conditions and in
reliance upon the representations and warranties herein set forth, the Company
agrees to sell to each Underwriter, and each Underwriter agrees, severally and
not jointly, to purchase from the Company, at a purchase price of      % of the
principal amount


                                        4

thereof, plus accrued interest on the Securities from           , 1995, to the
Closing Date, the principal amount of the Securities set forth opposite such
Underwriter's name in Schedule I hereto.

          3.   DELIVERY AND PAYMENT.  Delivery of and payment for the Securities
shall be made at the offices of Wachtell, Lipton, Rosen & Katz, 51 West 52nd

than          , 1995) as the Underwriters shall designate, which date and time
may be postponed by agreement between the Underwriters and the Company or as
provided in Section 9 hereof (such date and time of delivery and payment for the
Securities being herein called the "Closing Date").  Delivery of the Securities
shall be made to the Underwriters for the respective accounts of the several
Underwriters against payment by the several Underwriters of the purchase price
thereof to or upon the order of the Company by certified or official bank check
or checks drawn on or by a New York Clearing House Bank and payable in next day

          The Company agrees to have the Securities available for inspection,
checking and packaging by the Underwriters in New York, New York, not later than

          4.   OFFERING BY UNDERWRITERS.  After the Registration Statement
becomes effective the Underwriters will offer the Securities for sale to the
public on the terms and conditions as set forth in the Prospectus.  The
Underwriters agree to advise the Corporation promptly following the completion
of the distribution of the Securities.

          5.   AGREEMENTS.  The Company agrees with the several Underwriters
that:

          (a)  The Company will use its best efforts to cause the Registration
     Statement, if not effective at the Execution Time, and any amendment
     thereof, to become effective.  Prior to the termination of the offering of
     the Securities, the Company will not file any amendment of the Registration
     Statement or supplement to the Prospectus unless the Company has furnished
     you a copy for your review prior to filing and will not file any such
     proposed amendment or supplement without your prior written consent, which
     consent shall not be unreasonably withheld.  Subject to the foregoing
     sentence, if the Registration Statement has become or becomes effective
     pursuant to Rule 430A, or filing of the Prospectus is otherwise required
     under Rule 424(b), the Company will cause the Prospectus, properly com-
     pleted, and any supplement thereto, to be filed with the Commission
     pursuant to the applicable paragraph of Rule 424(b) within the time period
     prescribed and will provide evidence satisfactory to the Underwriters of
     such timely filing.  The Company will promptly advise the Underwriters (i)
     when the Registration Statement, if not effective at the Execution Time,
     and any amendment thereto, shall have become effective, (ii) when the Pro-
     spectus, and any supplement thereto, shall have been filed (if required)
     with the Commission pursuant to Rule 424(b), (iii) when, prior to
     termination of the offering of the Securities, any amendment to the
     Registration Statement shall have been filed or become effective, (iv) of
     any request by the Commission for any amendment of the Registration
     Statement or supplement to the Prospectus or for any additional informa-
     tion, (v) of the issuance by the Commission of any stop order suspending
     the effectiveness  of the Registration Statement or the institution or
     threatening of any proceeding for that purpose, and (vi) of the receipt by
     the Company of any notification with respect to the suspension of the
     qualification of the Securities for sale in any jurisdiction or the
     initiation or threatening of any proceeding for such purpose.  The Company
     will use its best efforts to prevent the issuance of any such stop order
     and, if issued, to obtain as soon as possible the withdrawal thereof.


                                        5

<PAGE>

          (b)  If, at any time when a prospectus relating to the Securities is
     required to be delivered under the Act, any event occurs as a result of
     which the Prospectus as then supplemented would include any untrue
     statement of a material fact or omit to state any material fact necessary
     to make the statements therein in the light of the circumstances under
     which they were made not misleading, or if it shall be necessary to amend
     the Registration Statement or supplement the Prospectus to comply with the
     Act or the Exchange Act or the respective rules thereunder, the Company
     promptly will (i) prepare and file with the Commission, subject to the
     second sentence of paragraph (a) of this Section 5, an amendment or
     supplement which will correct such statement or omission or effect such
     compliance and (ii) supply any supplemented Prospectus to you in such
     quantities as you may reasonably request.

          (c)  As soon as practicable, but in any event not later than sixteen
     (16) months after the Effective Date, the Company will make generally
     available to its security holders and to the Underwriters an earnings
     statement or statements of the Company and its subsidiaries which will
     satisfy the provisions of Section 11(a) of the Act and Rule 158 under the
     Act.  Filing reports under Section 13 of the Securities Exchange Act of
     1934 on a timely basis shall constitute compliance with this paragraph
     (iii), provided that the provisions of Section 11(a) of the Act and Rule
     158 are thereby satisfied.

          (d)  The Company will furnish to the Underwriters and counsel for the
     Underwriters, without charge, two signed copies of the Registration
     Statement (including exhibits thereto) and, so long as delivery of a
     prospectus by an Underwriter or dealer may be required by the Act, as many
     copies of each Preliminary Prospectus and the Prospectus and any supplement
     thereto as the Underwriters may reasonably request.  The Company will pay
     the expenses of printing or other production of all documents relating to
     the offering.

          (e)  The Company will cooperate with you and your counsel in
     connection with endeavoring to obtain qualification of the Securities for
     sale under the laws of such jurisdictions as the Underwriters may
     designate, will maintain such qualifications in effect so long as required
     for the distribution of the Securities and will pay the fee of the National
     Association of Securities Dealers Inc., in connection with the review of
     the offering; provided, however, that the Company shall not be obligated to
     qualify as a foreign corporation to do business under the laws of any
     jurisdiction in which it shall not then be qualified but for the
     requirements of this Section 5(e), to subject itself to taxation in any
     such jurisdiction to which it shall not then be so subject or to consent to
     general service of process in any such jurisdiction to which it shall not
     then be so subject.

          (f)  For a period beginning at the time of execution hereof and ending
     one business day after the Closing Date, the Company will not, without the
     prior consent of the Underwriters, offer, sell, contract to sell or
     otherwise dispose of any publicly sold (including pursuant to Rule 144A of
     the Securities Act) United States dollar-denominated debt securities issued
     or guaranteed by the Company and having a maturity of more than one year
     from the date of issue.

          (g)  The Company confirms as of the date hereof that it is in
     compliance with all provisions of Section 1 of Laws of Florida, Chapter 92-
     198, AN ACT RELATING TO DISCLOSURE OF DOING BUSINESS WITH CUBA, and the
     Company further agrees that if it commences engaging in business with the
     government of Cuba or with any person or affiliate located in Cuba after
     the date the Registration Statement becomes or has become effective with
     the Securities and Exchange Commission or with the Florida Department of
     Banking and Finance (the "Department"), whichever date is later, or if the
     information reported in the Prospectus, if any, concerning the Company's
     business with Cuba or with any person or affiliate located in Cuba changes


                                        6


<PAGE>

     in any material way, the Company will provide the Department notice of such
     business or change, as appropriate, in a form acceptable to the Department.

          (h)  The Company will apply, in all material respects, the net
     proceeds of the offering and the sale of the Securities in the manner set
     forth in the Prospectus under the caption "Use of Proceeds."


          6.   CONDITIONS TO THE OBLIGATIONS OF THE UNDERWRITERS.  The
obligations of the Underwriters to purchase the Securities shall be subject to
the accuracy of the representations and warranties on the part of the Company
contained herein as of the Execution Time and as of the Closing Date (as if made
at the Closing Date), to the accuracy of the statements of the Company made in
any certificates pursuant to the provisions hereof, to the performance by the
Company of its obligations hereunder and to the following additional conditions:

          (a)  If the Registration Statement has not become effective prior to
     the Execution Time, unless the Underwriters agree in writing to a later
     time, the Registration Statement will become effective not later than (i)

     offering price, if such determination occurred at or prior to 3:00 p.m. New
     York time on such date or (ii) 12:00 Noon on the business day following the
     day on which the public offering price was determined, if such deter-
     mination occurred after 3:00 p.m. New York time on such date; if filing of
     the Prospectus, or any supplement thereto, is required pursuant to Rule
     424(b), the Prospectus, and any such supplement, will be filed in the
     manner and within the time period required by Rule 424(b); and no stop
     order suspending the effectiveness of the Registration Statement shall have
     been issued and no proceedings for that purpose shall have been instituted
     or threatened.

          (b)  The Company shall have furnished to the Underwriters the opinion
     of Kirkland & Ellis, counsel for the Company as to paragraphs (i), (iv),

          Prospectus, and the Company and each of the Major Subsidiaries are
          duly qualified to do business as foreign corporations under the laws
          of each jurisdiction in which the character of the business conducted
          or the location of the properties owned or leased make such qualifi-
          cations necessary and in which the consequences of a failure to so
          qualify would have a material adverse effect on the properties or
          businesses of the Company and its subsidiaries taken as whole;


               (iii)  all the outstanding shares of capital stock of each Major
          Subsidiary have been duly and validly authorized and issued and are

          franchise, contract or other document of a character required to be
          described in the Registration Statement or Prospectus, or to be filed
          as an exhibit, which is not described or filed as required;

               (vii)  the Registration Statement and all post-effective
          amendments thereto have become effective under the Act; any required
          filing of the Prospectus, and any supplements thereto, pursuant to
          Rule 424(b) and Rule 430A have been made in the manner and within the
          time period required by such rules; to the best knowledge of such
          counsel no stop order suspending the effectiveness of the Registration
          Statement has been issued, no proceedings for that purpose have been
          instituted or threatened and the Registration Statement and the
          Prospectus (other than the financial statements and other financial
          and statistical information contained therein as to which such counsel
          need express no opinion) comply as to form in all material respects
          with the applicable requirements of the Act and the Trust Indenture
          Act and the respective rules thereunder;

               (viii)  this Agreement has been duly authorized, executed and
          delivered by the Company;

               (ix)  no consent, approval, authorization or order of any court
          or governmental agency or body is required for the consummation of the
          transactions contemplated herein, except such as have been obtained
          under the Act and such as may be required under the blue sky laws of
          any jurisdiction in connection with the purchase and distribution of
          the Securities by the Underwriters as to which such counsel need not
          opine and such other approvals as have been obtained;

               (x)  neither the execution and delivery of this Agreement nor the
          issue and sale of the Securities, nor the consummation of any other of
          the transactions contemplated herein or therein nor the fulfillment of
          the terms hereof or thereof will conflict with, result in a breach of,
          or constitute a default under  the charter or by-laws of the Company
          or the terms of any agreement listed on Exhibit A attached hereto;

               (xi)  neither the execution and delivery of this Agreement nor
          the issue and sale of the Securities, nor the consummation of any


                                        8

<PAGE>

          other of the transactions contemplated herein or therein nor the
          fulfillment of the terms hereof or thereof will conflict with, result
          in a breach of, or constitute a default under any agreement listed
          in Exhibit 10 of the  Company's Annual Report on Form 10-K for the
          year ended 1994 or under any judgment, order or regulation known
          to such counsel to be applicable to the Company or any of its
          subsidiaries of any court, regulatory body, administrative agency,
          governmental body or arbitrator having jurisdiction over the
          Company or any of its subsidiaries; and

               (xii)  no holders of securities of the Company have rights to the
          registration of such securities under the Registration Statement.

          Each of such counsel shall state that it has participated in
conferences with representatives of the Company, at which conferences the
contents of the Registration Statement, the Prospectus, each amendment thereof
and supplement thereto and related matters were discussed, and, although such
counsel has not independently checked or verified and is not passing upon and
assumes no responsibility for the factual accuracy, completeness or fairness of
the statements contained in the Registration Statement, the Prospectus, any
amendment thereof or supplement thereto, no facts have come to the attention of
such counsel to cause such counsel to believe (A) that either the Registration
Statement or any amendment thereto (other than the financial statements and
related schedules and other financial and statistical information contained
therein, or omitted therefrom), at the time the Registration Statement became
effective contained an untrue statement of a material fact or omitted to state a
material fact necessary to make the statements therein not misleading or (B)
that the Prospectus, as amended and supplemented (other than the financial
statements and related schedules and other financial and statistical information
contained therein, or omitted therefrom), at the time the Registration Statement
became effective or on each Closing Date contains an untrue statement of a
material fact or omits to state a material fact necessary to make the statements
therein, in the light of the circumstances under which they were made, not
misleading.

          In rendering such opinions, each such counsel may rely (A) as to
matters involving the application of laws of any jurisdiction other than the
States of Illinois and Delaware or the United States, to the extent they deem
proper and specified in such opinions, upon the opinion of other counsel of good
standing whom they believe to be reliable and who are satisfactory to counsel
for the Underwriters and (B) as to matters of fact, to the extent they deem
proper, on certificates of responsible officers of the Company and public
officials.  Reference to the Prospectus in this paragraph (b) include any sup-
plements thereto at the Closing Date.

          (c)  The Underwriters shall have received from Wachtell, Lipton, Rosen
     & Katz, counsel for the Underwriters, such opinion or opinions, dated the
     Closing Date, with respect to the issuance and sale of the Securities, the
     Indenture, the Registration Statement, the Prospectus (together with any
     supplement thereto) and other related matters as the Underwriters may
     reasonably require, and the Company shall have furnished to such counsel
     such documents as they reasonably request for the purpose of enabling them
     to pass upon such matters.

          (d)  The Company shall have furnished to the Underwriters a
     certificate of the Company, signed by the Chief Financial Officer and the
     Vice President Controller, each in his official capacity as an officer of
     the Company and not as an individual, dated the Closing Date, to the effect
     that the signers of such certificate have carefully examined the
     Registration Statement, the Prospectus, any supplement to the Prospectus
     and this Agreement and that:


                                        9

<PAGE>

               (i)  the representations and warranties of the Company in this
          Agreement are true and correct in all material respects on and as of
          the Closing Date with the same effect as if made on the Closing Date
          and the Company has complied with all the agreements and satisfied all
          the conditions on its part to be performed or satisfied at or prior to
          the Closing Date;

               (ii)  no stop order suspending the effectiveness of the
          Registration Statement has been issued and no proceedings for that
          purpose have been instituted or, to the Company's knowledge, threat-
          ened; and

               (iii)  since the date of the most recent financial statements
          included in the Prospectus (exclusive of  any supplement thereto),
          there has been no MAC, whether or not arising from transactions in the
          ordinary course of business, except as set forth in or contemplated in
          the Prospectus (exclusive of any supplement thereto).

          (e)  At the Execution Time and at the Closing Date, Arthur Andersen
     LLP shall have furnished to the Underwriters a letter or letters, dated
     respectively as of the Execution Time and as of the Closing Date, in form
     and substance satisfactory to the Underwriters, stating in effect that:

               (i)  They are independent certified public accountants with
          respect to the Company and its subsidiaries within the meaning of the
          Act and the applicable published rules and regulations thereunder;

               (ii)  In their opinion, the financial statements and any
          supplementary financial information and schedules examined by them and
          included in the Prospectus or the Registration Statement comply as to
          form in all material respects with the applicable accounting
          requirements of the Act and the related published rules and
          regulations thereunder; and, if applicable, they have made a review in
          accordance with standards established by the American Institute of
          Certified Public Accountants of the unaudited consolidated interim
          financial statements of the Company for the periods specified in such
          letter, as indicated in their reports thereon, copies of which have
          been furnished to the Underwriters;

               (iii)  The unaudited summary, condensed and selected financial
          information with respect to the consolidated results of operations and
          financial position of the Company for the _______ most recent fiscal
          years (or such shorter period as applicable) included in the
          Prospectus agrees with the corresponding amounts (after restatements
          where applicable) in the audited consolidated financial statements for
          such period; and the pro forma financial information complies in all
          material respects as to form with all applicable accounting
          requirements of the Act;

               (iv)  On the basis of limited procedures, not constituting an
          examination in accordance with generally accepted auditing standards,
          consisting of a reading of the unaudited financial statements and
          other information referred to below, a reading of the  latest
          available interim financial statements of the Company and its
          subsidiaries, inspection of the minute books of the Company and its
          subsidiaries since the date of the latest audited financial statements
          included in the Prospectus, inquiries of officials of the Company and
          its subsidiaries responsible for financial and accounting matters and
          such other inquiries and procedures as may be specified in such
          letter, nothing came to their attention that caused them to believe
          that:

                    (A)  the unaudited consolidated statements of income,
               consolidated balance sheets and consolidated statements of cash
               flows included in the Prospectus do not comply as to form in all


                                       10

<PAGE>

               material respects with the applicable accounting requirements of
               the Act and the related published rules and regulations
               thereunder, or are not in conformity with generally accepted ac-
               counting principles applied on a basis substantially consistent
               with the basis for the audited consolidated statements of income,
               consolidated balance sheets and consolidated statements of cash
               flows included in the Prospectus;

                    (B)  any other unaudited income statement data and balance
               sheet items included in the Prospectus do not agree with the
               corresponding items in the unaudited consolidated financial
               statements from which such data and items were derived, and any
               such unaudited data and items, if any, were not determined on a
               basis substantially consistent with the basis for the cor-
               responding amounts in the audited consolidated financial
               statements included in the Prospectus;

                    (C)  the unaudited financial statements which were not
               included in the Prospectus but from which were derived any
               unaudited condensed financial statements referred to in Clause A
               and any unaudited income statement data and balance sheet items
               included in the Prospectus and referred to in Clause B were not
               determined on a basis substantially consistent with the basis for
               the audited consolidated financial statements included in the
               Prospectus;

                    (D)  any unaudited pro forma consolidated condensed
               financial statements included in the  Prospectus do not comply as
               to form in all material respects with the applicable accounting
               requirements of the Act and the published rules and regulations
               thereunder or the pro forma adjustments have not been properly
               applied to the historical amounts in the compilation of those
               statements;

                    (E)  as of a specified date not more than five days prior to
               the date of such letter, there have been any changes in the
               consolidated capital stock or any increase in the consolidated
               total debt of the Company and its Subsidiaries, or any
               decreases in consolidated net current assets or net assets or
               other items specified prior to the Execution Time by the
               Underwriters, or any increases in any items specified prior to
               the Execution Time by the Underwriters, in each case as compared
               with amounts shown in the latest balance sheet included in the
               Prospectus, except in each case for changes, increases or
               decreases which the Prospectus discloses have occurred or may
               occur or which are described in such letter; and

                    (F)  for the period from the date of the latest financial
               statements included in the Prospectus to the specified date
               referred to in Clause E there were any decreases in consolidated
               net sales, operating profit data as compared to the preceding
               period or other items specified by the Underwriters, or any in-
               creases in any items specified prior to the Execution Time by the
               Underwriters, in each case as compared with the comparable period
               of the preceding year and with any other period of corresponding
               length specified prior to the Execution Time by the Underwriters,
               except in each  case for decreases or increases which the Pro-
               spectus discloses have occurred or may occur or which are
               described in such letter; and

               (v)  In addition to the examination referred to in their
          report(s) included in the Prospectus and the limited procedures,
          inspection of minute books, inquiries and other procedures referred to
          in paragraphs (ii) and (iv) above, they have carried out certain


                                       11

<PAGE>

          specified procedures, not constituting an examination in accordance
          with generally accepted auditing standards, with respect to certain
          amounts,  percentages and financial information specified prior to the
          Execution Time by the Underwriters, which are derived from the general
          accounting records of the Company and its Subsidiaries, which appear
          in the Prospectus, or in Part II of, or in exhibits and schedules to,
          the Registration Statement specified prior to the Execution Time by
          the Underwriters, and have compared certain of such amounts, percent-
          ages and financial information with the accounting records of the
          Company and the Subsidiaries and have found them to be in agreement.

          References to the Prospectus in this paragraph (e) include any
     supplement thereto at the date of the letter.

          (f)  Subsequent to the Execution Time or, if earlier, the dates as of
     which information is given in the Registration Statement (exclusive of any
     amendment thereof) and the Prospectus (exclusive of any supplement
     thereto), there shall not have been (i) any change or decrease specified in
     the letter or letters referred to in paragraph (e) of this Section 6 or
     (ii) any change, or any development involving a prospective change, in or
     affecting the business or properties of the Company and its subsidiaries
     the effect of which, in any case referred to in clause (i) or (ii) above,
     is, in the judgment of the Underwriters, so material and adverse as to make
     it impractical or inadvisable to proceed with the public offering or
     delivery of the Securities as contemplated by the Registration Statement
     (exclusive of any amendment thereof) and the Prospectus (exclusive of any
     supplement thereto).

          (g)  Subsequent to the Execution Time, there shall not have been any
     decrease in the rating of any of the Company's debt securities by any
     "nationally recognized statistical rating organization" (as defined for
     purposes of Rule 436(g) under the Act) or any notice given of any intended
     or potential decrease in any such rating or of a possible change in any
     such rating that does not indicate the direction of the possible change.

          (h)  Prior to the Closing Date, the Company shall have furnished to
     the Underwriters such further information, certificates and documents as
     the Underwriters may reasonably request.

          If any of the conditions specified in this Section 6 shall not have
been fulfilled in all material respects when and as provided in this Agreement,
or if any of the opinions and certificates mentioned above or elsewhere in this
Agreement  shall not be in all material respects reasonably satisfactory in form
and substance to the Underwriters and counsel for the Underwriters, this
Agreement and all obligations of the Underwriters hereunder may be canceled at,
or at any time prior to, the Closing Date by the Underwriters.  Notice of such
cancellation shall be given to the Company in writing or by telephone or
telegraph confirmed in writing.

          7.   REIMBURSEMENT OF UNDERWRITERS' EXPENSES.  If the sale of the
Securities provided for herein is not consummated because any condition to the
obligations of the Underwriters set forth in Section 6 hereof is not satisfied
(other than conditions specified in Sections 6(c) and, if the Underwriters shall
not have exercised their judgment reasonably, 6(f)), because of any termination
pursuant to Section 10 hereof or because of any refusal, inability or failure on
the part of the Company to perform any agreement herein or comply with any
provision hereof other than by reason of a default by any of the Underwriters,
the Company will reimburse the Underwriters severally upon demand for all out-
of-pocket expenses (including reasonable fees and disbursements of counsel) that
shall have been incurred by them in connection with the proposed purchase and
sale of the Securities.

          8.   INDEMNIFICATION AND CONTRIBUTION.  A.  The Company agrees to
indemnify and hold harmless each Underwriter, the directors, officers, employees
and agents of each Underwriter and each person who controls any Underwriter
within the meaning of either the Act or the Securities Exchange Act of 1934 (the
"Exchange Act")


                                       12

<PAGE>

against any and all losses, claims, damages or liabilities, joint or several, to
which they or any of them may become subject under the Act, the Exchange Act or
other Federal or state statutory law or regulation, at common law or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained in the registration statement for the
registration of the Securities as originally filed or in any amendment thereof,
or in any Preliminary Prospectus or the Prospectus, or in any amendment thereof
or supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and agrees to reimburse
each such indemnified party, as incurred, for any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability or action; PROVIDED, HOWEVER, that (i) the
Company will not be liable in any such case to the extent that any such loss,
claim, damage or liability arises out of or is based upon any such untrue
statement or alleged untrue  statement or omission or alleged omission made
therein in reliance upon and in conformity with written information furnished to
the Company by or on behalf of any Underwriter specifically for use in
connection with the preparation thereof, (ii) the Company will not be liable for
the amount paid in settlement of any litigation commenced or threatened or of
any claim whatsoever arising out of or based upon any (actual or alleged) untrue
statement or omission unless such settlement is effected with the written
consent of the Company and (iii) such indemnity with respect to any Preliminary
Prospectus shall not inure to the benefit of an Underwriter (or any person
controlling such Underwriter) from whom the person asserting any such loss,
claim, damage or liability purchased the Securities which are the subject
thereof if such person did not receive a copy of the Prospectus (or the Pro-
spectus as supplemented) excluding documents incorporated therein by reference
at or prior to the confirmation of the sale of such Securities to such person in
any case where such delivery is required by the Act and the untrue statement or
omission of a material fact contained in such Preliminary Prospectus was
corrected in the Prospectus (or the Prospectus as supplemented).  This indemnity
agreement will be in addition to any liability which the Company may otherwise
have.

     (b)  Each Underwriter severally agrees to indemnify and hold harmless the
Company, each of its directors, each of its officers who signs the Registration
Statement, and each person who controls the Company within the meaning of either
the Act or the Exchange Act, to the same extent as the foregoing indemnity in
paragraph (a) of this Section from the Company to each Underwriter, but only
with reference to written information relating to such Underwriter furnished to
the Company by or on behalf of such Underwriter through the Underwriters
specifically for inclusion in the documents referred to in the foregoing
indemnity.  This indemnity agreement will be in addition to any liability which
any Underwriter may otherwise have.  The Company acknowledges that the
statements set forth in the last paragraph of the cover page and under the
heading "Underwriting" in any Preliminary Prospectus and the Prospectus
constitute the only information furnished in writing by or on behalf of the
several Underwriters for inclusion in any Preliminary Prospectus or the
Prospectus, and you, as the Underwriters, confirm that such statements are
correct.

     (c)  Promptly after receipt by an indemnified party under this Section 8 of
notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 8, notify the indemnifying party in writing of the commencement thereof;
but the failure so to notify the indemnifying party (i) will not relieve it from
liability under paragraph (a) or (b) above unless and to the extent it did not
otherwise learn of such action and such failure results in the forfeiture by the
indemnifying party of any material right or defense and (ii) will not, in any
event, relieve the indemnifying party from any obligations to any indemnified
party other than the indemnification obligation provided in paragraph (a) or (b)
above.  The indemnifying party shall be entitled to appoint counsel of the
indemnifying party's choice at the indemnifying party's expense to represent the
indemnified party in any action for which indemnification is sought (in which
case the indemnifying party shall not thereafter be responsible for the fees and
expenses of any separate counsel retained by the indemnified party or parties
except as set forth below); PROVIDED, HOWEVER, that such counsel shall be
satisfactory to the indemnified party.  Notwithstanding


                                       13

<PAGE>

the indemnifying party's election to appoint counsel to represent the indemni-
fied party in an action, the indemnified party shall have the right to employ
separate counsel (including local counsel), and the indemnifying party shall
bear the reasonable fees, costs and expenses of such separate counsel if (i) the
use of counsel chosen by the indemnifying party to represent the indemnified
party would present such counsel in its reasonable judgment with a conflict of
interest, (ii) the actual or potential defendants in, or targets of, any such
action include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be legal
defenses available to it and/or other indemnified parties which are different
from or additional to those available to the indemnifying party, (iii) the
indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent the indemnified party within a reasonable time
after notice of the institution of such action or (iv) the indemnifying party
shall authorize the indemnified party to employ separate counsel at the expense
of the indemnifying party.  It being understood and agreed that the indemnifying
party shall bear the fees, costs and expenses of only one counsel pursuant to
this paragraph.  An indemnifying party will not, without the prior written
consent of the indemnified parties, settle or compromise or consent to the entry
of any judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability
arising out of such claim, action, suit or proceeding.  No indemnifying party
shall be liable for any settlement of any  commenced or threatened action or
proceeding effected without its written consent.

          (d)  In the event that the indemnity provided in paragraph (a) or (b)
of this Section 8 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, the Company and the Underwriters agree to
contribute to the aggregate losses, claims, damages and liabilities (including
legal or other expenses reasonably incurred in connection with investigating or
defending same) (collectively "Losses") to which the Company and one or more of
the Underwriters may be subject in such proportion as is appropriate to reflect
the relative fault of the indemnifying party on the one hand and the indemnified
party on the other hand; PROVIDED, HOWEVER, that in no case shall any
Underwriter (except as may be provided in any agreement among underwriters
relating to the offering of the Securities) be responsible for any amount in ex-
cess of the underwriting discount or commission applicable to the Securities
purchased by such Underwriter hereunder.  If the allocation provided by the
immediately preceding sentence is unavailable for any reason, or if such
allocation provides a lesser sum to the indemnified party than the amount
hereinafter calculated then the Company and the Underwriters shall contribute in
such proportion as is appropriate to reflect not only such relative fault but
also the relative benefits of the indemnifying party and the indemnified party
as well as any other equitable considerations.  Benefits received by the Company
shall be deemed to be equal to the net proceeds from the offering (before
deducting expenses) received by the Company and benefits received by the
Underwriters shall be deemed to be equal to the total underwriting discounts and
commissions, in each case as set forth on the cover page of the Prospectus.
Relative fault shall be determined by reference to whether any alleged untrue
statement or omission relates to information provided by the Company or the
Underwriters.  The Company and the Underwriters agree that it would not be just
and equitable if contribution were determined by pro rata allocation or any
other method of allocation which does not take account of the equitable
considerations referred to above.  Notwithstanding the provisions of this
Section 8(d) no person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation.  For purposes of
this Section 8, each person who controls the Underwriter within the meaning of
either the Act or the Exchange Act and each director, officer, employee and
agent of the Underwriter shall have the same rights to contribution as the Un-
derwriter and each person who controls the Company within the meaning of either
the Act or the Exchange Act, each officer of the Company who shall have signed
the Registration Statement  and each director of the Company shall have the same
rights to contribution as the Company, subject in each case to the applicable
terms and provisions of this Section 8(d).

          9.   DEFAULT BY AN UNDERWRITER.  If any one or more Underwriters shall
fail to purchase and pay for any of the Securities agreed to be purchased by
such Underwriter or Underwriters hereunder and such failure to purchase shall
constitute a default in the performance of its or their obligations under this
Agreement, the remaining Underwriters shall be obligated severally to take up
and pay for (in the respective proportions which the principal amount of Securi-
ties set forth opposite their names in Schedule I hereto bears to the aggregate
principal amount of Securities set forth opposite the names of all the remaining
Underwriters) the Securities which the defaulting Underwriter or Underwriters
agreed but failed to purchase; PROVIDED, HOWEVER, that in the event that the
aggregate principal amount of Securities which the defaulting Underwriter or
Underwriters agreed but failed to purchase shall exceed 10% of the aggregate
principal amount of Securities set forth in Schedule I hereto, the remaining
Underwriters shall have the right to purchase all, but shall not be under any
obligation to purchase any, of the Securities, and if such nondefaulting Un-
derwriters do not purchase all the Securities, this Agreement will terminate
without liability to any nondefaulting Underwriter or the Company.  In the event
of a default by any Underwriter as set forth in this Section 9, the Closing Date
shall be postponed for such period, not exceeding seven days, as the
Underwriters shall determine in order that the required changes in the
Registration Statement and the Prospectus or in any other documents or
arrangements may be effected.  Nothing contained in this Agreement shall relieve
any defaulting Underwriter of its liability, if any, to the Company and any
nondefaulting Underwriter for damages occasioned by its default hereunder.

          10.  TERMINATION.  This Agreement shall be subject to termination in
the absolute discretion of the Underwriters, by notice given to the Company
prior to delivery of and payment for the Securities, if prior to such time (i)
trading in the common stock of Company shall have been suspended by the Secu-
rities and Exchange Commission or the New York Stock Exchange or trading in
securities generally on the New York Stock Exchange shall have been suspended or
limited or minimum prices shall have been established on such Exchange, (ii) a
banking moratorium shall have been declared either by Federal or New York State
authorities or (iii) there shall have occurred any outbreak or escalation of
hostilities, declaration by the United States of war or other calamity or crisis
the effect of which on the financial markets in the United States is such as  to
make it, in the judgment of the Underwriters, impracticable to market the
Securities.

          11.  REPRESENTATIONS AND INDEMNITIES TO SURVIVE.  The respective
agreements, representations, warranties, indemnities and other statements of the
Company or its officers and of the Underwriters set forth in or made pursuant to
this Agreement will remain in full force and effect, regardless of any inves-
tigation made by or on behalf of any Underwriter or the Company or any of the
officers, directors or controlling persons referred to in Section 8 hereof, and
will survive delivery of and payment for the Securities.  The provisions of
Sections 7 and 8 hereof shall survive the termination or cancellation of this
Agreement.

          12.  NOTICES.  All communications hereunder will be in writing and

binding upon the parties hereto and their respective successors and the officers
and directors and controlling persons referred to in Section 8 hereof, and no
other person will have any right or obligation hereunder.

          14.  APPLICABLE LAW.  This Agreement will be governed by and construed
in accordance with the laws of the State of New York, without giving affect to
the conflicts of laws principles thereof.

USG Corporation

Chicago, IL 60606-4678

Ladies and Gentlemen:
   
     We have acted as special counsel to USG Corporation, a Delaware corporation
(the "Corporation"), in connection with the  registration by the Corporation of
$150 million aggregate principal amount of senior notes (the "Notes")
pursuant to a Registration Statement on Form S-3 (File No. 33-60563) filed with
the Securities and Exchange Commission under the Securities Act of 1933, as
subsequently amended or supplemented (the Registration Statement, as amended or
supplemented is hereinafter referred to as the "Registration Statement").
    
   
          In that connection, we have examined originals, or copies certified or
otherwise identified to our satisfaction, of such documents, corporate records
and other instruments as we have deemed necessary for the purposes of this
opinion, including (i) the Restated Certificate of Incorporation of the
Corporation; (ii) the Amended and Restated By-laws of the Corporation; (iii)
minutes and records of the corporate proceedings of the Corporation with respect
to the issuance of the Notes; (iv) the Registration Statement and exhibits
thereto; and (v) originals, or copies certified or otherwise identified to our
satisfaction, of such other documents, corporate records and other instruments
as we have deemed necessary for the purpose of this opinion and such other
matters of fact and law which we have deemed necessary in order to render this
opinion.
    
          For purposes of this opinion, we have assumed the authenticity of all
documents submitted to us as originals, the conformity to the originals of all
documents submitted to us as copies, and the authenticity of the originals of
all documents submitted to us as copies.  We have also assumed the genuineness
of the signatures of persons signing all documents in connection with which this
opinion is rendered, the authority of such persons signing on behalf of the
parties thereto other than the Corporation, and the due authorization, execution
and delivery of all documents by the parties thereto other than the Corporation.




<PAGE>

          Based on the foregoing, we are of the opinion that:

          (1)  The Corporation is a corporation validly existing under the laws
     of the State of Delaware.
   
          (2)  When the Board of Directors of the Company, or the Special
     Committee authorized by the Board, has designated the type, terms and
     amount of the Notes to be issued as contemplated by the Registration
     Statement, the sale and issuance of the Notes will be validly authorized.
    
   
          (3)  When the Notes have been duly executed and authenticated on
     behalf of the Corporation, duly authenticated and delivered by the Trustee
     under the Indenture and issued and paid for in accordance with the terms
     set forth in the Prospectus forming a part of the Registration
     Statement, they will constitute legal, valid and binding instruments
     enforceable in accordance with their terms, except that (a) our opinion
     is subject to the effect of bankruptcy, insolvency, reorganization,
     arrangement, moratorium, fraudulent conveyance and other similar laws, and
     (b) the binding effect and enforceability of agreements and the
     availability of injunctive relief or other equitable remedies thereunder
     are subject to public policy considerations and the effect of general
     principles of equity (regardless of whether enforcement is considered in
     proceedings at law or in equity).
    
          We hereby consent to the filing of this opinion with the Securities
and Exchange Commission as an exhibit to the Registration Statement and to the
reference to this firm under the caption "Legal Matters" in the Prospectus
forming a part of such Registration Statement.

          We do not find it necessary for purposes of this opinion, and
accordingly do not purport to cover herein, the application of the securities or
"Blue Sky" laws of the various states to issuance of the Notes.  We render no
opinion as to the laws of any jurisdiction other than the internal law of the
State of Illinois and the United States of America and the internal corporate
law of the State of Delaware.

          This opinion is furnished to you in connection with the filing of the
Registration Statement, and is not to be used, circulated, quoted or otherwise
relied upon for any other purpose.

                                   Very truly yours,
                                   KIRKLAND & ELLIS

          This CREDIT AGREEMENT dated as of July [__], 1995 (as the same may be

Date.

          Accordingly, the Borrower, the Lenders, the Issuing Banks and the

hereto.

          "ALTERNATE BASE RATE" shall mean, for any day, a rate per annum

Three-Month Secondary CD Rate and (ii) Statutory Reserves and (b) the

<PAGE>

Assessment Rate.  "ASSESSMENT RATE" shall mean for any date the annual rate
(rounded upwards, if necessary, to the next 1/100 of 1%) most recently estimated
by Chemical Bank as the then current net annual assessment rate that will be

Insurance Corporation (or any successor) for insurance by such Corporation (or
such successor) of time deposits made in dollars at Chemical Bank's domestic
offices.  "STATUTORY RESERVES" shall mean a fraction (expressed as a decimal),
the numerator of which is the number one and the denominator of which is the

If for any reason the Agent shall have determined (which determination shall be
conclusive absent manifest error) that it is unable to ascertain the Base CD

inability or failure of the Agent to obtain sufficient quotations in accordance
with the terms thereof, the Alternate Base Rate shall be determined without
regard to CLAUSE (b) or (c), or both, of the first sentence of this definition,
as appropriate, until the circumstances giving rise to such inability no longer
exist.  Any change in the Alternate Base Rate due to a change in the Prime Rate,
the Three-Month Secondary CD Rate or the Federal Funds Effective Rate shall be

Three-Month Secondary CD Rate or the Federal Funds Effective Rate, respectively.

     less than or equal to 1.50 to 1.0       20.00

          For purposes of the foregoing, the Applicable Commitment Fee at any

calculating the Debt/EBITDA Ratio for purposes of this definition, Debt shall
not include obligations with respect to letters of credit (including Letters of

such letters of credit are not drawn on or, if and to the extent drawn on, such

of a demand for reimbursement following payment on the letter of credit.
Following the end of any such fiscal quarter, any change in the Applicable

          For purposes of the foregoing, the Applicable Eurodollar Margin at any

day of the Borrower's most recently ended fiscal quarter, PROVIDED, that, in
calculating the Debt/EBITDA Ratio for purposes of this definition, Debt shall
not include obligations with respect to letters of credit (including Letters of
Credit issued hereunder) entered into in the ordinary course of

<PAGE>

business and having an aggregate outstanding face amount of up to $50,000,000 to
the extent such letters of credit are not drawn on or, if and to the extent

the Applicable Eurodollar Margin shall become effective for all purposes on and
after the earlier of (i) the date of delivery to the Agent of the Debt/EBITDA
Ratio Certificate and (ii) the date of delivery to the Agent of the Financial
Officer's certificate and applicable financial statements described in SECTIONS
5.07(a), (b) and (c) relating to such fiscal quarter; PROVIDED, HOWEVER, that
until either the Debt/EBITDA Ratio Certificate or such certificate and financial

same Borrowing under this Agreement shall be made by the Lenders simultaneously
and proportionately to their respective Pro Rata Shares, it being understood
that no Lender shall be responsible for any failure by any other Lender to
perform its obligation to make a Revolving Loan hereunder and that the Revolving
Credit Commitment of any Lender shall not be increased or decreased without the
prior written consent of such Lender as a result of the failure by any other
Lender to perform its obligation to make a Revolving Loan.  The failure of any
Lender to make available to the Agent its Pro Rata Share of any Borrowing shall
not relieve any other Lender of its obligation hereunder to make available to
the Agent such other Lender's Pro Rata Share of such Borrowing on the date such
funds are to be made available pursuant to the terms of this Agreement.

          (b)  Each Revolving Loan Borrowing shall be in a minimum principal
amount of $5,000,000 and in multiples of $1,000,000 in excess thereof or in an
aggregate principal amount equal to the Revolving Credit Availability.  Each
Revolving Loan Borrowing shall be comprised entirely of ABR Loans or Eurodollar
Loans, as the Borrower may request pursuant to SECTION 2.03.  Each Lender may at
its option fulfill its commitment with respect to any Eurodollar Loan by causing
any domestic or foreign branch or Affiliate of such Lender to make such
Eurodollar Loan; PROVIDED that any exercise of such option shall not affect the
obligation of the Borrower to repay such Eurodollar Loan in accordance with the
terms of this Agreement, and PROVIDED, FURTHER, that the Borrower shall not be
responsible for any costs or expenses associated with such Lender's exercise of
such option.  Borrowings of more than one Type may be outstanding at the same
time; PROVIDED, HOWEVER, that the Borrower shall not be entitled to request any
Borrowing which, if made, would result in an aggregate of more than ten separate
Borrowings of Revolving Loans which are Eurodollar Loans being outstanding
hereunder at any one time.

          (c)  Subject to PARAGRAPH (e) below, each Lender shall make a
Revolving Loan in the amount of its Pro Rata Share of the amount of each
Revolving Loan Borrowing hereunder on the proposed date thereof by wire transfer
of immediately available funds to the Agent in New York, New York, not later
than 11:00 a.m., New York City time, and the Agent shall, promptly upon receipt
of such amounts but in any event not later than 2:00 p.m. on the same Business
Day, New York City time, credit the amounts so received to the general deposit
account of the Borrower with the Agent or, if a Revolving Loan Borrowing shall
not occur on such date because any condition precedent herein specified shall
not have been met, return the amounts so received to the respective Lenders.
Unless the Agent shall have received notice from a Lender prior to the date of
any Revolving Loan Borrowing that such Lender will not make available to the
Agent such Lender's portion of such Borrowing, the Agent may assume that such
Lender has made such portion available to the Agent on the date of such
Borrowing in accordance with this PARAGRAPH (c) and the Agent may, in reliance
upon such assumption, make available to the Borrower on such date a
corresponding amount.  If and to the extent that such Lender shall not have made
such portion available to the Agent, such Lender and the Borrower severally
agree to repay to the Agent forthwith on demand such corresponding amount
together with interest thereon, for each day from the date such amount is made
available to the Borrower until the date such amount is repaid to the Agent at
(i) in the case of the Borrower, the interest rate applicable at the time to the
Revolving Loans comprising such Borrowing and (ii) in the case of such Lender,
the Federal Funds Effective Rate.  If such Lender shall repay to the Agent such
corresponding amount, such amount shall constitute such Lender's Revolving Loan
as part of such Borrowing for purposes of this Agreement.

          (d)  Notwithstanding any other provision of this Agreement, the
Borrower shall not be entitled to request any Revolving Loan Borrowing if the
Interest Period requested with respect thereto would end after the Maturity
Date.

          (e)  The Borrower may refinance all or any part of any Revolving Loan
Borrowing with a Borrowing of the same or a different Type, subject to

<PAGE>

the conditions and limitations set forth in this Agreement.  Any Borrowing or
part thereof so refinanced shall be deemed to be repaid or prepaid in accordance
with SECTION 2.06 or 2.13, as applicable, with the proceeds of a new Borrowing,
and the proceeds of the new Borrowing, to the extent they do not exceed the
principal amount of the Borrowing being refinanced, shall not be paid by the
Lenders to the Agent or by the Agent to the Borrower pursuant to PARAGRAPH (c)
above.

          SECTION 2.03.  NOTICE OF BORROWINGS OF REVOLVING LOANS. The Borrower

such notice, then the Borrower shall be deemed to have selected an Interest
Period of one month's duration.  If the Borrower shall not have given notice in
accordance with this SECTION 2.03 of its election to refinance a Revolving Loan
Borrowing prior to the end of the Interest Period in effect for such Borrowing,
then the Borrower shall (unless such Borrowing is repaid at the end of such
Interest Period) be deemed to have given notice of an election to refinance such

date of such Borrowing (which shall be a Business Day) and (iii) whether the

last day of the Interest Period relating thereto and (y) the Termination Date.
The Agent, in its sole discretion, may reject a Notice of Competitive Bid
Borrowing that does not conform substantially to the format of EXHIBIT E, and
the Agent shall promptly notify the Borrower of such rejection.  The Agent shall
promptly (but in any event on the same Business Day on which such notice was
tendered) notify each Lender of each such request for a Competitive Bid
Borrowing that it has received from the Borrower and has not rejected by
telecopying such Lender a notice in the form of EXHIBIT F (a "NOTICE OF
COMPETITIVE BID REQUEST").

          (b) Each Lender (or any branch, office or Affiliate of such Lender on

conform substantially to the format of EXHIBIT G may be rejected by the Agent
after conferring with, and upon the instruction of, the Borrower, and the Agent
shall notify the Lender making such nonconforming Competitive Bid, or the Lender
on behalf of which such nonconforming Competitive Bid has been made, of such
rejection as soon as practicable.  Each Competitive Bid shall refer to this
Agreement and shall specify (x) the principal amount (which shall be in a
minimum principal amount of $5,000,000 and in a integral multiple of $1,000,000
in excess thereof and which may equal the entire principal amount of the
Competitive Bid Borrowing requested by the Borrower) of each Competitive Bid
Loan that the applicable Lender is willing to make to the Borrower, (y) with
respect to each requested Fixed Rate Loan, the Competitive Bid Rate, or with
respect to each requested Eurodollar Loan, the Spread, at which such Lender is
prepared to make such Competitive Bid Loan and (z) the Interest Period (which
shall be the Interest Period set forth in the applicable Competitive Bid
Request) and the last day thereof.  If any Lender shall elect not to make a
Competitive Bid, such Lender shall so notify the Agent via telecopier (I) in the
case of Eurodollar Loans, not later than 10:00 a.m., New York City time, three
Business Days before a proposed Competitive Bid Borrowing, and (II) in the case
of Fixed Rate Loans, not later than 10:00 a.m., New York City time, on the day
of a proposed Competitive Bid Borrowing; PROVIDED, HOWEVER, that any Lender's
failure to give such notice shall not cause such Lender to be obligated to make
any Competitive Bid Loan as part of such Competitive Bid Borrowing.  A
Competitive Bid submitted by or on behalf of a Lender pursuant to this SECTION
2.04 shall be irrevocable.

          (c)  The Agent shall promptly notify the Borrower by telephone and
telecopier of all the Competitive Bids made, the Competitive Bid Rate and the
principal amount of each Competitive Bid Loan in respect of which a Competitive
Bid was made and the identity of the Lender that made each Competitive Bid.  The
Agent shall send a copy of all Competitive Bids to the Borrower for its records
as soon as practicable (but in any event within one Business Day) after
completion of the bidding process set forth in this SECTION 2.04.

          (d)  The Borrower may in its sole and absolute discretion, subject
only to the provisions of this SECTION 2.04, accept or reject any Competitive
Bid referred to in SECTION 2.04(b).  The Borrower shall notify the Agent by
telephone, confirmed by telecopier in the form of a Competitive Bid Accept/
Reject Letter, whether and to what extent it has decided to accept or reject any
of or all the Competitive Bids referred to in SECTION 2.04(b), (x) in the case
of a Competitive Bid Borrowing of Eurodollar Loans, not later than 11:00 a.m.,
New York City time, three Business Days before a proposed Competitive Bid
Borrowing, and (y) in the case of a Borrowing of Fixed Rate Loans, not later
than 11:00 a.m., New York City time, on the day of a proposed Competitive Bid
Borrowing; PROVIDED, HOWEVER, that (i) the Borrower's failure to give such
notice shall be deemed to be a rejection of all the Competitive Bids referred to
in SECTION 2.04(b), (ii) the Borrower shall not accept a Competitive Bid made at
a particular Competitive Bid Rate if the Borrower has decided to reject a
Competitive Bid made at a lower Competitive Bid Rate, (iii) the aggregate amount
of the Competitive Bids accepted by the Borrower shall not exceed the principal
amount specified in the Notice of Competitive Bid Borrowing, (iv) if the
Borrower shall accept a Competitive Bid or Competitive Bids made at a particular
Competitive Bid Rate but the amount of such Competitive Bid or Competitive Bids
shall cause the total amount of Competitive Bids to be accepted by the Borrower
to exceed the amount specified in the Notice of Competitive Bid Borrowing, then
the Borrower shall accept a portion of such Competitive Bid or Competitive Bids
in an amount equal to the

<PAGE>

amount specified in the Competitive Bids accepted with respect to such Notice of
Competitive Bid Borrowing, which acceptance, in the case of multiple Competitive
Bids at the highest Competitive Bid Rate accepted by the Borrower, shall be made
pro rata in accordance with the amount of each such Competitive Bid at such
Competitive Bid Rate, and (v) except pursuant to CLAUSE (iv) above, no
Competitive Bid shall be accepted for a Competitive Bid Loan unless such
Competitive Bid Loan is in a minimum principal amount of $5,000,000 or an
integral multiple of $1,000,000 in excess thereof; PROVIDED FURTHER, however,
that if a Competitive Bid Loan must be in an amount less than $5,000,000 because
of the provisions of CLAUSE (iv) above, such Competitive Bid Loan may be for a
minimum of $1,000,000 or any integral multiple thereof, and in calculating the
pro rata allocation of acceptances of portions of multiple Competitive Bids at a
particular Competitive Bid Rate pursuant to CLAUSE (iv) the amounts shall be
rounded to integral multiples of $1,000,000 in a manner which shall be in the
discretion of the Borrower.  A notice given by the Borrower pursuant to this
SECTION 2.04 shall be irrevocable.

          (e)  The Agent shall promptly notify each Lender  that submitted a
Competitive Bid, or on behalf of which a Competitive Bid was submitted, as the
case may be, whether or not such Competitive Bid has been accepted (and if so,
in what amount and at what Competitive Bid Rate) by telecopy.  Upon the
Borrower's acceptance of any Competitive Bid, the Lender that made such
Competitive Bid, or the Lender on behalf of which such Competitive Bid was made,
as the case may be, will thereupon become bound, subject to the other applicable
conditions hereof, to make the Competitive Bid Loan in respect of which such
Competitive Bid has been accepted.

          (f)  If the Agent shall elect to submit a Competitive Bid in its
capacity as a Lender, it shall submit such Competitive Bid directly to the
Borrower one quarter of an hour earlier than the latest time at which the other
Lenders are required to submit their Competitive Bids to the Agent pursuant to
SECTION 2.04(b).

          SECTION 2.05.  NOTES.  (a)  The Borrower shall execute and deliver to
each Lender (or to the Agent on behalf of each Lender) on or before the Closing
Date a promissory note substantially in the form of EXHIBIT H-1 (each a
"REVOLVING LOAN NOTE" and collectively, the "REVOLVING LOAN NOTES") to evidence
the aggregate amount of that Lender's Revolving Loans and with other appropriate
insertions.  Each Revolving Loan Note shall be dated the Closing Date and shall
be stated to mature on the Termination Date.  The Revolving Loan Note executed
in favor of any Lender shall be in a principal amount equal to such Lender's
Revolving Credit Commitment.

          (b)  The Borrower's obligation to pay the principal of and interest on
all Competitive Bid Loans made to it by a Lender shall be evidenced by its
promissory note substantially in the form of EXHIBIT H-2 (each a "COMPETITIVE
BID NOTE" and collectively, the "COMPETITIVE BID NOTES").  Each Competitive Bid
Note issued to each Lender (i) shall be payable to the order of such Lender and
be dated the Closing Date, (ii) shall be in a stated principal amount equal to
the Aggregate Revolving Credit Commitments and be payable in the outstanding
principal amount of Competitive Bid Loans owing to such Lender evidenced thereby
from time to time, (iii) shall mature with respect to each Competitive Bid Loan
evidenced thereby on the earlier of (x) the last day of the Interest Period
applicable thereto and (y) the Termination Date, (iv) shall bear interest as
provided in SECTION 2.08 in respect of Fixed Rate Loans or Eurodollar Loans, as
the case may be, evidenced thereby and (v) shall be entitled to the benefits of
this Agreement and the other Loan Documents.

          (c)  Each Lender is hereby authorized to, and prior to any transfer of
any Note issued to it, each Lender shall, endorse the date and amount of each
Loan made by such Lender and each payment or prepayment of principal of the
Loans evidenced thereby on the schedule annexed to and constituting a part of
such Note, which endorsement shall constitute PRIMA FACIE evidence, absent
manifest error, of the accuracy of the information so endorsed; provided that
failure by any such Lender to make such endorsement

<PAGE>

shall not affect the obligations of the Borrower hereunder or under such Note.
In lieu of endorsing such schedule as hereinabove provided, prior to any
transfer of such Note, each Lender is hereby authorized, at its option, to
record such Loans and such payments or prepayments in its books and records,
such books and records constituting PRIMA FACIE evidence, absent manifest error,
of the accuracy of the information contained therein.

          SECTION 2.06.  REPAYMENT OF LOANS. (a) The Borrower agrees to pay the
outstanding principal balance of each Revolving Loan on the Termination Date and
each Competitive Bid Loan as provided in SECTION 2.04(a).  Each Loan shall bear
interest from the date of the Borrowing of which such Loan is a part on the
outstanding principal balance thereof as set forth in SECTION 2.08.

          (b)  Each Lender shall, and is hereby authorized by the Borrower to,
maintain in accordance with its usual practices records evidencing the
indebtedness of the Borrower to such Lender hereunder from time to time,
including the amounts and Types of and Interest Periods applicable to the Loans
made by such Lender from time to time and the amounts of principal and interest
paid to such Lender from time to time in respect of such Loans.

          (c)  The entries made in the records maintained pursuant to PARAGRAPH
(b) of this SECTION 2.06 and in the Register maintained by the Agent pursuant to
SECTION 9.04 shall be PRIMA FACIE evidence of the existence and amounts of the
Borrower's obligations to which such entries relate; PROVIDED, HOWEVER, that the
failure of any Lender or the Agent to maintain or to make any entry in such
records or the Register, as applicable, or any error therein, shall not in any
manner affect the Borrower's obligation to repay the Loans in accordance with
the terms of this Agreement.

          SECTION 2.07. FEES. (a) The Borrower agrees to pay to the Lenders,
through the Agent, on the last day of March, June, September and December in
each year and on the date on which the last of the Commitments shall expire or
be terminated as provided herein, a commitment fee (a "COMMITMENT FEE") accruing
at an annual rate equal to the Applicable Commitment Fee on the average daily
excess of the Aggregate Revolving Credit Commitments over the sum of (i) the
aggregate outstanding principal balance of all Revolving Loans and (ii) the LC
Exposure.  The Commitment Fee shall be payable to the Lenders pro rata in
arrears from the Closing Date until the date on which the last of the Revolving
Credit Commitments of such Lenders shall expire or be terminated as provided
herein.  All Commitment Fees shall be computed on the basis of the actual number
of days elapsed in a year of 360 days.

          (b)   The Borrower agrees to pay to each Lender, through the Agent, on
the last day of March, June, September and December in each year, and on the
date on which the LC Commitment of such Lender shall have been terminated or
reduced to zero as provided herein and all Letters of Credit issued pursuant to
such LC Commitment shall have expired, a letter of credit fee (an "LC FEE")
equal to the Applicable Eurodollar Margin on the average daily undrawn face
amount of all outstanding Letters of Credit, payable to the Lenders pro rata in
arrears.  All LC Fees shall be computed on the basis of the actual number of
days elapsed in a year of 360 days, as the case may be.

          (c)   The Borrower agrees to pay to each Issuing Bank, for its own
account, the applicable Issuing Bank Fees.

          (d)  All Fees shall be paid on the dates due in immediately available
funds.  All Fees, other than the Issuing Bank Fees, shall be paid to the Agent
for distribution, if and as appropriate, among the Lenders and to the Issuing
Banks.  Once paid, none of the Fees shall be refundable under any circumstances,
except in the case of overpayment, inadvertent or otherwise.

          SECTION 2.08.  INTEREST ON LOANS.  (a) Subject to the provisions of
SECTION 2.09, the Revolving Loans comprising each ABR Borrowing shall bear
interest (computed on the basis of the actual number of days elapsed over a year
of 365 or 366 days, as the case may be, when determined by reference to

<PAGE>

the Prime Rate and over a year of 360 days at all other times) at a rate per
annum equal to the Alternate Base Rate.

          (b)  Subject to the provisions of SECTION 2.09, the Revolving Loans
comprising each Eurodollar Borrowing shall bear interest (computed on the basis
of the actual number of days elapsed over a year of 360 days) at a rate per
annum equal to the LIBO Rate in effect for such Borrowing plus the Applicable
Eurodollar Margin.

          (c)  Subject to the provisions of SECTION 2.09, each Fixed Rate Loan
shall bear interest (computed on the basis of the actual number of days elapsed
over a year of 360 days) at the rate offered by the Lender making such Loan and
accepted by the Borrower pursuant to SECTION 2.04(d).

          (d)   Subject to the provisions of SECTION 2.09, each Eurodollar Loan
comprising any Competitive Bid Borrowing shall bear interest (computed on the
basis of the actual number of days elapsed over a year of 360 days) at the LIBO
Rate plus the applicable Spread offered by the Lender making such Loan and
accepted by the Borrower pursuant to SECTION 2.04(d) above.

          (e)  Interest on each Loan shall be payable on the Interest Payment
Dates applicable to such Loan except as otherwise provided in this Agreement.
The applicable Alternate Base Rate or LIBO Rate for each Interest Period or day
within an Interest Period, as the case may be, shall be determined by the Agent,
and such determination shall be conclusive absent manifest error.

          SECTION 2.09.  DEFAULT INTEREST.  If the Borrower shall default in the
payment of the principal of or interest on any Loan or any other amount becoming
due hereunder, by acceleration or otherwise, the Borrower shall on demand from
time to time pay interest, to the extent permitted by law, on such defaulted
amount up to (but not including) the date of actual payment (after as well as
before judgment) at a rate per annum (computed on the basis of the actual number
of days elapsed over a year of 365 or 366 days, as the case may be, in the case
of amounts bearing interest computed by reference to the Prime Rate and a year
of 360 days in all other cases) equal to (a) in the case of any Loan, the rate
applicable to such Loan under SECTION 2.08 plus 2% per annum and (b) in the case
of any other amount, the rate that would at the time be applicable to an ABR
Loan under SECTION 2.08 plus 2% per annum.

          SECTION 2.10.  ALTERNATE RATE OF INTEREST.  In the event, and on each
occasion, that on the day two Business Days prior to the commencement of any
Interest Period for any Borrowing constituting Eurodollar Loans, the Agent shall
have determined that dollar deposits in the principal amounts of Loans
constituting such Eurodollar Loans are not generally available in the London
interbank market, or that the rates at which such dollar deposits are being
offered will not adequately and fairly reflect the cost to any Lender of making
or maintaining its Eurodollar Loan during such Interest Period, or that
reasonable means do not exist for ascertaining the LIBO Rate, the Agent shall,
as soon as practicable thereafter, give written or telecopy notice of such
determination to the Borrower and the Lenders.  In the event of any such
determination, any request by the Borrower for Eurodollar Loans pursuant to
SECTION 2.03 or 2.12 shall, until the Agent shall have advised the Borrower and
the Lenders that the circumstances giving rise to such notice no longer exist,
be deemed to be a request for ABR Loans; PROVIDED, HOWEVER, that the Borrower
may revoke any such deemed request for ABR Loans by providing written or
telecopy notice to the Agent no later than the end of the Business Day before
the day such ABR Loans are to be made.  Each determination by the Agent
hereunder shall be conclusive absent manifest error.

          SECTION 2.11.  REDUCTION OR CANCELLATION OF COMMITMENTS.  (a)  The
Revolving Credit Commitments and the LC Commitments shall be automatically
terminated on the Maturity Date.

          (b)  If the Debt/EBITDA Ratio exceeds 2.5 to 1.0 as of the fiscal
quarter ended June 30, 2000, the Revolving Credit Commitments shall be

<PAGE>

permanently reduced (i) by $50,000,000 effective upon the date the financial
statements for such quarter are delivered to the Agent (or, if such financial
statements are not delivered within five days following the due date therefor,
the Debt/EBITDA Ratio shall be deemed for purposes of this PARAGRAPH (b) to
exceed 2.5 to 1.0 for such quarter, and such reduction to the Revolving Credit
Commitments shall be effective as of such fifth day following the date such
financial statements were due) and (ii) by an additional $50,000,000 effective
one year following the date of such initial reduction.

          (c)   Upon at least ten days prior irrevocable written or telecopy
notice to the Agent, which shall promptly notify the Lenders, the Borrower may
at any time and from time to time permanently reduce all or a portion of the
Aggregate Revolving Credit Commitments; PROVIDED, that any partial reduction of
the Aggregate Revolving Credit Commitments shall be in minimum amounts of
$10,000,000 and in $1,000,000 increments in excess thereof.

          (d)  Each reduction in the Revolving Credit Commitments hereunder
shall be made ratably among the Lenders in accordance with their respective Pro
Rata Shares.

          (e)  If at any time the Aggregate Revolving Credit Commitments are
reduced below the Aggregate LC Commitments, then the Aggregate LC Commitments
will be automatically and immediately reduced to the amount of the Aggregate
Revolving Credit Commitments.

          SECTION 2.12.  CONVERSION AND CONTINUATION OF BORROWINGS OF REVOLVING
LOANS.  The Borrower shall have the right, with respect to any Revolving Loan
Borrowing, at any time upon prior irrevocable notice to the Agent (i) not later
than 12:00 (noon), New York City time, one Business Day prior to conversion, to
convert any Eurodollar Borrowing into an ABR Borrowing, (ii) not later than
12:00 noon, New York City time, three Business Days prior to conversion or
continuation, to convert any ABR Borrowing into a Eurodollar Borrowing or to
continue any Eurodollar Borrowing as a Eurodollar Borrowing at the end of the
Interest Period relating thereto for an additional Interest Period, and (iii)
not later than 12:00 noon, New York City time, three Business Days prior to
conversion, to convert the Interest Period with respect to any Eurodollar
Borrowing to another permissible Interest Period, subject in each case to the
following:

          (a)  each conversion or continuation shall be made pro rata among the
     Lenders in accordance with their respective Pro Rata Shares;

          (b)  if less than all the outstanding principal amount of any
     Revolving Loan Borrowing shall be converted or continued, the aggregate
     principal amount of such Borrowing converted or continued shall be an
     integral multiple of $1,000,000 (and not less than $5,000,000 in the case
     of a conversion into, or a continuation of, a Eurodollar Borrowing);

          (c)  each conversion shall be effected by each Lender by applying the
     proceeds of the new Revolving Loan of such Lender resulting from such
     conversion to the Revolving Loan (or portion thereof) of such Lender being
     converted;

          (d)  if any Eurodollar Borrowing (or the Interest Period with respect
     thereto) is converted at a time other than the end of the Interest Period
     applicable thereto, the Borrower shall pay, upon demand, any amounts due to
     the Lenders pursuant to SECTION 2.18;

          Each notice pursuant to this SECTION 2.12 shall be in substantially
the form of EXHIBIT I.  Such notice shall be irrevocable and shall refer to this
Agreement and specify (i) the identity and amount of the Revolving Loan
Borrowing that the Borrower requests be converted or continued, (ii) whether
such Borrowing is to be converted to or continued as a Eurodollar Borrowing or
an ABR Borrowing, (iii) if such notice requests a conversion, the date of such
conversion (which shall be a Business Day) and (iv) if such

<PAGE>

Borrowing is to be converted to or continued as a Eurodollar Borrowing, the
Interest Period with respect thereto.  If no Interest Period is specified in any
such notice with respect to any conversion to or continuation as a Eurodollar
Borrowing, the Borrower shall be deemed to have selected an Interest Period of
one month's duration.  The Agent shall advise the other Lenders of any notice
given pursuant to this SECTION 2.12 and of each such Lender's portion of any
converted or continued Revolving Loan Borrowing.  If the Borrower shall not have
given notice in accordance with this SECTION 2.12 to continue any Revolving Loan
Borrowing of Eurodollar Loans into a subsequent Interest Period (and shall not
otherwise have given notice in accordance with this SECTION 2.12 to convert such
Borrowing), such Borrowing shall, at the end of the Interest Period applicable
thereto (unless repaid pursuant to the terms hereof), automatically be continued
into a new Interest Period as an ABR Borrowing.

          SECTION 2.13.  VOLUNTARY PREPAYMENTS.  (a)  The Borrower shall have
the right at any time and from time to time to prepay Revolving Loans, in whole
or in part, upon prior written or telecopy notice (or telephone notice promptly
confirmed by written or telecopy notice) to the Agent before 12:00 noon, New
York City time, (i) three Business Days prior to prepayment, in the case of
Eurodollar Loans; and (ii) one Business Day prior to prepayment, in the case of
ABR Loans; PROVIDED, HOWEVER, that each partial prepayment shall be in an amount
which is an integral multiple of $1,000,000.  Competitive Bid Borrowings may not
be prepaid unless so required pursuant to the terms hereof.

          (b)  Each notice of an optional prepayment shall specify the
prepayment date and the principal amount of Revolving Loans to be prepaid, shall
be irrevocable and shall commit the Borrower to prepay such Revolving Loans by
the amount stated therein on the date stated therein.  All optional prepayments
under this SECTION 2.13 shall be subject to SECTION 2.18 but otherwise without
premium or penalty.  All prepayments of Eurodollar Loans under this SECTION 2.13
shall be accompanied by accrued interest on the principal amount being prepaid
to the date of payment.

          SECTION 2.14.  MANDATORY PREPAYMENTS OF REVOLVING LOANS.  On the date
of any termination or reduction of the Revolving Credit Commitments pursuant to
SECTION 2.11, the Borrower shall pay or prepay so much of the Revolving Loans as
shall be necessary in order that (a) the sum of (i) the aggregate principal
amount of the Loans outstanding and (ii) the LC Exposure will not exceed (b) the
Aggregate Revolving Credit Commitments after giving effect to such termination
or reduction.  Any such prepayment shall be subject to the provisions of SECTION
2.18.  All prepayments of Eurodollar Loans under this SECTION 2.14 shall be
accompanied by accrued interest on the principal amount being prepaid to the
date of payment.

          SECTION 2.15.  LETTERS OF CREDIT.  (a) Subject to the terms and
conditions and relying upon the representations and warranties herein set forth,
each Issuing Bank agrees, at any time and from time to time on or after the
Closing Date until the earlier of the Maturity Date and the termination of the
LC Commitments in accordance with the terms hereof, to issue and deliver or to
extend the expiry date of Letters of Credit for the account of the Borrower in
an aggregate undrawn amount at any one time outstanding which, together with the
aggregate undrawn amount at such time outstanding of Letters of Credit issued by
other Issuing Banks, does not exceed the Aggregate LC Commitments; PROVIDED,
HOWEVER, that no Issuing Bank shall issue or extend the expiry of any Letter of
Credit if, immediately after giving effect to such issuance or extension (i) the
aggregate LC Exposure at such time would exceed the Aggregate LC Commitments or
(ii) the sum of the aggregate outstanding principal balance of the Loans and the
LC Exposure would exceed the Aggregate Revolving Credit Commitments.  Each
Letter of Credit (x) shall be in a form approved in writing by the Borrower, the
Agent and the applicable Issuing Bank and (y) shall permit drawings upon the
presentation of one or more sight drafts and such other documents as shall be
specified by the Borrower in the applicable notice delivered pursuant to
PARAGRAPH (c) below.

<PAGE>

          (b)  Each Letter of Credit shall by its terms expire not later than
the earlier of (i) the first anniversary of the date of issuance or the date of
the most recent extension (subject to extension for additional one-year periods
by the applicable Issuing Bank as contemplated by PARAGRAPH (a) above) and (ii)
the Maturity Date.  Each Letter of Credit shall by its terms provide for payment
of drawings in dollars.

          (c)  The Borrower shall give the applicable Issuing Bank irrevocable
written or telecopy notice not later than 12:00 noon, New York City time, three
Business Days (or such shorter period as shall be acceptable to such Issuing
Bank and the Agent) prior to any proposed issuance or proposed extension of the
expiry date of a Letter of Credit.  Each such notice shall refer to this
Agreement and shall specify (I) the date on which such Letter of Credit is to be
issued (which shall be a Business Day), the face amount of such Letter of Credit
(which shall be an amount in dollars), (ii) the name and address of the
beneficiary, (iii) whether such Letter of Credit shall permit a single drawing
or multiple drawings, (iv) the form of the sight draft and any other documents
required to be presented at the time of any drawing (together with the exact
wording of such documents or copies thereof) and (v) the expiry date of such
Letter of Credit (which shall conform to the provisions of PARAGRAPH (b) above).
Each Issuing Bank shall give the Agent, which shall in turn give to each other
Issuing Bank and to each Lender, prompt written or telecopy advice of any notice
received from the Borrower pursuant to this paragraph.

          (d)  By the issuance of a Letter of Credit and without any further
action on the part of the applicable Issuing Bank or the Lenders in respect of
such Letter of Credit, the applicable Issuing Bank hereby grants to each Lender,
and each Lender hereby agrees to and does acquire from such Issuing Bank, a
participation in such Letter of Credit equal to such Lender's Pro Rata Share of
any drawing thereunder, of the face amount of such Letter of Credit, effective
upon the issuance of such Letter of Credit; PROVIDED, HOWEVER, that no Lender
shall be required to acquire participations in Letters of Credit that would
result in its Pro Rata Share of the LC Exposure exceeding its LC Commitment.  In
consideration and in furtherance of the foregoing, each Lender hereby absolutely
and unconditionally agrees to pay to the Agent, on behalf of each Issuing Bank,
in accordance with PARAGRAPH (f) below, such Lender's Pro Rata Share of each
unreimbursed LC Disbursement made by such Issuing Bank; PROVIDED, HOWEVER, that
the Lenders shall not be obligated to make any such payment with respect to any
wrongful payment or disbursement made under any Letter of Credit as a result of
the gross negligence or willful misconduct of such Issuing Bank.

          (e)  Each Lender acknowledges and agrees that its acquisition of
participations pursuant to PARAGRAPH (d) above in respect of Letters of Credit
is absolute and unconditional and shall not be affected by any circumstance
whatsoever, including the occurrence and continuance of any Potential Event of
Default or Event of Default, and that each such payment shall be made without
any offset, abatement, withholding or reduction whatsoever.

          (f)  Promptly after it shall have ascertained that any draft and any
accompanying documents presented under a Letter of Credit appear to be in
conformity with the terms and conditions of such Letter of Credit, the
applicable Issuing Bank shall give written or telecopy notice to the Borrower
and the Agent of the receipt and amount of such draft and the date on which
payment thereon will be made.  If the Agent shall not have received from the
Borrower the payment required pursuant to PARAGRAPH (g) below by 12:00 noon, New
York City time, one Business Day after the date on which payment of a draft
presented under any Letter of Credit has been made, the Agent shall promptly so
notify the applicable Issuing Bank and each Lender, specifying in the notice to
each Lender its Pro Rata Share on the date of such notice, of such LC
Disbursement.  Each Lender shall pay to the Agent, not later than 2:00 p.m., New
York City time, on such date, such Lender's Pro Rata Share of such LC
Disbursement, which the Agent shall promptly pay to the applicable Issuing Bank.
Each such payment by a Lender pursuant to this PARAGRAPH (f) in respect of any
LC Disbursement shall be deemed to be a Revolving Loan made to the

<PAGE>

Borrower, and all such Revolving Loans made in respect of any one LC
Disbursement shall be deemed to be a Revolving Loan Borrowing.  The Revolving
Loans constituting such Borrowing initially shall accrue interest at the
Alternate Base Rate.  The Borrower hereby irrevocably authorizes the Lenders to
make such Revolving Loans for the purpose of paying an Issuing Bank for any LC
Disbursements which the Borrower fails to pay (together with any interest on the
LC Disbursement for the period prior to the making of such Revolving Loans) and
agrees that all such Loans so made shall be deemed to have been requested by the
Borrower.

          (g)  If an Issuing Bank shall pay any draft presented under a Letter
of Credit under circumstances entitling it to reimbursement under succeeding
provisions of this PARAGRAPH (g), the Borrower shall pay to such Issuing Bank or
to the Agent for the account of such Issuing Bank or, if the Agent shall have
received the payments provided in PARAGRAPH (f) above with respect to such
drawing, for the accounts of the Lenders, an amount equal to the amount of such
draft before 12:00 noon, New York City time, on the Business Day immediately
following the date of payment of such draft, together with interest on such
amount at a rate per annum equal to the interest rate in effect for ABR
Borrowings from (and including) the date of payment of such draft to (but
excluding) the date of such payment by the Borrower.  The obligation of the
Borrower to pay the amounts referred to above in this PARAGRAPH (g) shall be
absolute, unconditional and irrevocable and shall be satisfied strictly in
accordance with their terms irrespective of:

          (I)  any lack of validity or enforceability of any Letter of Credit;

          (ii)  the existence of any claim, setoff, defense or other right which
     the Borrower or any other Person may at any time have against the
     beneficiary under any Letter of Credit, the Agent, any Issuing Bank, any
     confirming bank or any Lender (other than the defense of payment in
     accordance with the terms of this Agreement or a defense based on gross
     negligence or willful misconduct of the applicable Issuing Bank or
     confirming bank) or any other Person in connection with this Agreement or
     any other transaction;

          (iii)  any draft or other document presented under a Letter of Credit
     proving to be forged, fraudulent or invalid in any respect or any statement
     therein being untrue or inaccurate in any respect; PROVIDED that payment by
     the applicable Issuing Bank or confirming bank under such Letter of Credit
     against presentation of such draft or document shall not have constituted
     gross negligence or willful misconduct by such Person;

          (iv)  payment by the applicable Issuing Bank under a Letter of Credit
     against presentation of a draft or other document which does not comply in
     any immaterial respect with the terms of such Letter of Credit; PROVIDED
     that such payment shall not have constituted gross negligence or willful
     misconduct; or

          (v)  any other circumstance or event whatsoever, whether or not
     similar to any of the foregoing; PROVIDED that such other circumstance or
     event shall not have been the result of gross negligence or willful
     misconduct of the applicable Issuing Bank.

          It is understood that in making any payment under a Letter of Credit
(x) the applicable Issuing Bank's exclusive reliance on the documents presented
to it under such Letter of Credit as to any and all matters set forth therein,
including, without limitation, reliance on the amount of any draft presented
under such Letter of Credit, whether or not the amount due to the beneficiary
equals the amount of such draft and whether or not any document presented
pursuant to such Letter of Credit proves to be forged, fraudulent or invalid in
any respect, if such document on its face appears to be in order, and whether or
not any other statement or any other document presented pursuant to such Letter
of Credit proves to be forged or invalid or

<PAGE>

any statement therein proves to be inaccurate or untrue in any respect
whatsoever, and (y) any noncompliance in any immaterial respect of the documents
presented under a Letter of Credit with the terms thereof shall, in either case,
not be deemed willful misconduct or gross negligence of such Issuing Bank.

          (h)  TRANSITIONAL PROVISIONS.  SCHEDULE 2.15 contains a schedule of
certain letters of credit issued for the account of the Borrower or an Affiliate
thereof and outstanding as of the Closing Date by one or more of the Issuing
Banks (the "EXISTING FACILITY LETTERS OF CREDIT").  On the Closing Date, (I)
such Existing Facility Letters of Credit shall be deemed to be Letters of Credit
issued pursuant to and in compliance with this SECTION 2.15, (ii) the face
amount of such Existing Facility Letters of Credit shall be included in the
calculation of the available LC Commitment and the LC Exposure, (iii) the
provisions of this SECTION 2.15 shall apply thereto, and the Borrower and the
Lenders hereunder hereby expressly assume all obligations with respect to such
Letters of Credit and (iv) all liabilities of the Borrower with respect to such
Existing Facility Letters of Credit shall constitute Obligations.

          SECTION 2.16. ADDITIONAL INTEREST ON EURODOLLAR LOANS; RESERVE
REQUIREMENTS; CHANGE IN CIRCUMSTANCES.  (a) The Borrower shall pay to the Agent
for the account of each Lender, so long as such Lender shall be required under
regulations of the Board to maintain reserves with respect to liabilities or
assets consisting of or including "Eurocurrency Liabilities" (as such term is
defined in Regulation D), additional interest on the unpaid principal amount of
each Eurodollar Loan of such Lender, from the date of such Loan until such Loan
ceases to be a Eurodollar Loan, at an interest rate per annum equal to all times
to the remainder obtained by subtracting (I) the LIBO Rate for the Interest
Period for such Loan from (ii) the rate obtained by dividing such LIBO Rate by a
percentage equal to 100% minus the Eurodollar Rate Reserve Percentage of such
Lender for such Interest Period, payable on each date on which interest is
payable on such Loan.  Such additional interest shall be determined by such
Lender and notified to the Borrower through the Agent.  For purposes of this
Section, "EURODOLLAR RATE RESERVE PERCENTAGE" of any Lender for the Interest
Period for any Eurodollar Loan means the reserve percentage applicable during
such Interest Period and actually required to be maintained by such Lender as a
result of the funding of Eurodollar Loans made by such Lender to the Borrower
hereunder (or if more than one such percentage shall be so applicable, the daily
average of such percentages for those days in such Interest Period during which
any such percentage shall be so applicable) under regulations issued from time
to time by the Board (or any successor) for determining the maximum reserve
requirement (including, without limitation, any emergency, supplemental or other
marginal reserve requirement) for such Lender with respect to liabilities or
assets consisting of or including Eurocurrency Liabilities having a term equal
to such Interest Period.

          (b)  Notwithstanding any other provision herein, if after the Closing
Date any change in applicable law or regulation or in the interpretation or
administration thereof by any governmental authority charged with the
interpretation or administration thereof (whether or not having the force of
law) shall change the basis of taxation of payments to any Lender of the
principal of or interest on any of such Lender's Loans or any other amounts
payable hereunder (other than taxes imposed on the overall net income of such
Lender) or shall impose, modify or deem applicable any reserve, special deposit
or similar requirement against assets of, deposits with or for the account of,
or credit extended by, such Lender or shall impose on such Lender or the London
interbank market any other condition affecting this Agreement or such Lender's
Loans, and the result of any of the foregoing shall be to increase the cost to
such Lender of making or maintaining any Loan or to reduce the amount of any sum
received or receivable by such Lender hereunder (whether of principal, interest
or otherwise) in respect thereof by an amount deemed by such Lender to be
material, then such additional amount or amounts as will compensate such Lender
for such additional costs or reduction will be paid to such Lender by the
Borrower upon demand by such Lender.

<PAGE>

          (c)  If any Lender or Issuing Bank shall have determined that the
applicability of any law, rule, regulation, agreement or guideline adopted
pursuant to or arising out of the July 1988 report of the Basle Committee on
Banking Regulations and Supervisory Practices entitled "International
Convergence of Capital Measurement and Capital Standards", or the adoption after
the date hereof of any other law, rule, regulation, agreement or guideline
regarding capital adequacy, or any change in any of the foregoing or in the
interpretation or administration of any of the foregoing by any governmental
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by any Lender (or any lending office of
such Lender) or Issuing Bank or any Lender's or Issuing Bank's holding company
with any request or directive regarding capital adequacy (whether or not having
the force of law) of any such authority, central bank or comparable agency, has
had the effect of reducing the rate of return on such Lender's or Issuing Bank's
capital or on the capital of such Lender's or Issuing Bank's holding company, if
any, as a consequence of this Agreement or the Loans made by such Lender or the
Letters of Credit issued by such Issuing Bank pursuant hereto (or the
participations of the Lenders therein) to a level below that which such Lender
or Issuing Bank or such Lender's or Issuing Bank's holding company could have
achieved but for such applicability, adoption, change or compliance (taking into
consideration such Lender's or Issuing Bank's policies and the policies of such
Lender's or Issuing Bank's holding company with respect to capital adequacy) by
an amount deemed by such Lender or Issuing Bank to be material, then from time
to time the Borrower shall pay to such Lender or Issuing Bank such additional
amount or amounts as will compensate such Lender or Issuing Bank or such
Lender's or Issuing Bank's holding company on an after-tax basis for any such
reduction suffered.  Notwithstanding the foregoing, no Lender shall be entitled
to compensation under this SECTION 2.16 with respect to any Competitive Bid Loan
if it knew or should have known of the change giving rise to such request and of
the impact of such change on the cost of making such Competitive Bid Loans at
the time of submission of the Competitive Bid pursuant to which such Competitive
Bid Loan shall have been made.

          (d)  A certificate of each Lender or Issuing Bank setting forth such
amount or amounts as shall be necessary to compensate such Lender or Issuing
Bank or its holding company as specified in PARAGRAPH (a), (b) or (c) above, as
the case may be, shall be delivered to the Borrower, which certificate shall be
rebuttably presumptive evidence of such costs or reductions.  The Borrower shall
pay each such Lender, Issuing Bank and holding company the amount shown as due
on any such certificate delivered by it within 10 Business Days after the
Borrower's receipt of the same; PROVIDED, that the Borrower shall have no
obligation to pay such costs or reductions to the extent such costs or
reductions were incurred by any such Lender, Issuing Bank or holding company
more than ninety (90) days prior to the date of the certificate in which such
costs or reductions were set forth.

          (e)  Except as otherwise expressly provided in this paragraph, failure
on the part of any Lender or Issuing Bank to demand compensation for any
increased costs or reduction in amounts received or receivable or reduction in
return on capital with respect to any period shall not constitute a waiver of
such Lender's or Issuing Bank's right to demand compensation with respect to
such period or any other period.  The protection of this SECTION 2.16 shall be
available to each Lender and Issuing Bank regardless of any possible contention
of the invalidity or inapplicability of the law, rule, regulation, guideline or
other change or condition which shall have occurred or been imposed.  No Lender
or Issuing Bank shall be entitled to compensation under this SECTION 2.16 for
any costs incurred or reductions suffered with respect to any date unless it
shall have notified the Borrower that it will demand compensation for such costs
or reductions under PARAGRAPH (c) above not more than six months after the later
of (I) such date and (ii) the date on which it shall have become aware of such
costs or reductions.

          SECTION 2.17.  CHANGE IN LEGALITY.  (a) Notwithstanding any other
provision herein, if any change in any law or regulation or in the
interpretation thereof by any Governmental Authority charged with the

<PAGE>

administration or interpretation thereof shall make it unlawful for any Lender
to make or maintain any Eurodollar Loan or to give effect to its obligations as
contemplated hereby with respect to any Eurodollar Loan, then, by written notice
to the Borrower and to the Agent, such Lender may:

          (I)   declare that Eurodollar Loans will not thereafter be made or
     maintained by such Lender hereunder, whereupon (y) any request by the
     Borrower for Eurodollar Loans shall, as to such Lender only, be deemed a
     request for an ABR Loan; and (z) any request by the Borrower to continue
     Eurodollar Loans or to convert into Eurodollar Loans shall, as to such
     Lender only, be deemed a request to convert into or continue as an ABR
     Loan; in either case unless such declaration shall be subsequently
     withdrawn; and

          (ii)  require that all outstanding Eurodollar Loans made by it be
     converted to ABR Loans, in which event all such Eurodollar Loans shall be
     automatically converted to ABR Loans as of the effective date of such
     notice as provided in PARAGRAPH (b) below.

In the event any Lender shall exercise its rights under (I) or (ii) above, all
payments and prepayments of principal which would otherwise have been applied to
repay the Eurodollar Loans that would have been made by such Lender or the
converted Eurodollar Loans of such Lender shall instead be applied to repay the
ABR Loans made by such Lender in lieu of, or resulting from the conversion of,
such Eurodollar Loans.  Notwithstanding the foregoing, no Lender shall be
entitled to compensation under this SECTION 2.17 with respect to any Competitive
Bid Loan and no Competitive Bid Loan shall be deemed converted to an ABR Loan if
such Lender knew or should have known of the change giving rise to such request
and of the impact of such change on the cost of making such Competitive Bid
Loans at the time of submission of the Competitive Bid pursuant to which such
Competitive Bid Loan shall have been made.

          (b)  For purposes of this SECTION 2.17, a notice to the Borrower by
any Lender shall be effective as to each Eurodollar Loan, if lawful, on the last
day of the Interest Period currently applicable to such Eurodollar Loan; in all
other cases such notice shall be effective on the date of receipt by the
Borrower.

          (c)  In the event that such Lender determines at any time following
its giving of the notice referred to in SECTION 2.17(a) that such Lender may
lawfully make Eurodollar Loans, such Lender shall promptly give notice (by
telephone confirmed in writing) to the Borrower and the Agent (which notice the
Agent shall promptly transmit to each Lender) of that determination, whereupon
the right of the Borrower to request of such Lender and such Lender's obligation
to make Eurodollar Loans shall be restored.

          (d)  Each Lender agrees (to the extent consistent with internal
policies) to designate a different lending office for Eurodollar Loans if such
designation would avoid the illegality described in SECTION 2.17(a); PROVIDED,
HOWEVER, that such designation need not be made if it would result in any
additional costs, expenses or risks to such Lender that are not reimbursed by
the Borrower pursuant hereto or would, in the reasonable judgment of such
Lender, be otherwise disadvantageous to such Lender.

          SECTION 2.18.  INDEMNITY.  The Borrower shall indemnify each Lender
against any loss or expense which such Lender may sustain or incur as a
consequence of (a) any failure by the Borrower to borrow or to refinance,
convert or continue any Loan hereunder after irrevocable notice of such
borrowing, refinancing, conversion or continuation has been given pursuant to
SECTION 2.03, 2.04 or 2.12 (b) any payment, prepayment or conversion of a
Eurodollar Loan required by any other provision of this Agreement or otherwise
made or deemed made on a date other than the last day of the Interest Period
applicable thereto, (c) any default in payment or prepayment of the principal
amount of any Loan or any part thereof or interest accrued thereon, as and when
due and payable (at the due date thereof, whether by scheduled maturity,
acceleration, irrevocable notice of prepayment or otherwise) or (d) the

<PAGE>

occurrence of any Event of Default, including, in each such case, any loss or
reasonable expense sustained or incurred or to be sustained or incurred in
liquidating or employing deposits from third parties acquired to effect or
maintain such Loan or any part thereof as a Eurodollar Loan.  Such loss or
reasonable expense shall be an amount equal to the excess, if any, as reasonably
determined by such Lender, of (I) its cost of obtaining the funds for the Loan
being paid, prepaid, converted or not borrowed, converted, continued,
refinanced, paid or prepaid (assumed to be the LIBO Rate applicable thereto) for
the period from the date of such payment, prepayment, conversion or failure to
borrow, convert, continue, refinance, pay or prepay to the last day of the
Interest Period for such Loan (or, in the case of a failure to borrow, convert,
continue or refinance, the Interest Period for such Loan which would have
commenced on the date of such failure) over (ii) the amount of interest (as
reasonably determined by such Lender) that would be realized by such Lender in
reemploying the funds so paid, prepaid, converted or not borrowed, converted,
continued, refinanced, paid or prepaid for such period or Interest Period, as
the case may be.  A certificate of any Lender setting forth any amount or
amounts which such Lender is entitled to receive pursuant to this Section shall
be delivered to the Borrower and shall be conclusive absent manifest error.

          SECTION 2.19.  PRO RATA TREATMENT.  (a)  Except as required under
SECTION 2.17 and SECTION 9.18, each Revolving Loan Borrowing, each payment or
prepayment of principal of any Revolving Loans, each payment of interest on the
Revolving Loans, each payment of the Commitment Fees and LC Fees, each reduction
of the Revolving Credit Commitments or the LC Commitments, and each refinancing
of any Revolving Loan Borrowing with, conversion of any Revolving Loan Borrowing
to or continuation of any Revolving Loan Borrowing as a Borrowing of any Type
(other than with respect to Competitive Bid Borrowings) shall be allocated among
the Lenders in accordance with their respective Pro Rata Shares.  Each Lender
agrees that in computing such Lender's portion of any Revolving Loan Borrowing
to be made hereunder, the Agent may, in its discretion, round each Lender's
percentage of such Borrowing, computed in accordance with SECTION 2.01, to the
next higher or lower whole dollar amount.

          (b)  All payments of principal of any Competitive Bid Borrowing shall
be allocated pro rata among the Lenders participating in such Borrowing in
accordance with the respective principal amounts of their outstanding
Competitive Bid Loans comprising such Borrowing.  All payments of interest on
any Competitive Bid Borrowing shall be allocated pro rata among the Lenders
participating in such Borrowing in accordance with the respective amounts of
accrued and unpaid interest on their outstanding Competitive Bid Loans
comprising such Borrowing.

          (c)  So long as the Loans have not become due and payable in full
pursuant to SECTION 7.02, and subject to the terms and conditions of this
Agreement, the Borrower shall designate whether any payment hereunder is to be
applied to a Revolving Loan Borrowing or a Competitive Bid Borrowing.  After the
Loans have become due and payable in full pursuant to SECTION 7.02, all amounts
remitted to the Agent shall be applied, subject to the provisions of this
Agreement, (I) first, to pay Obligations in respect of any fees, expense
reimbursements or indemnities then due to the Agent from the Borrower under this
Agreement or any other Loan Document; (ii) second, to pay Obligations in respect
of any fees, expense reimbursements or indemnities then due to the Lenders and
the Issuing Banks from the Borrower; (iii) third, to pay interest due in respect
of the Loans (ratably, in respect of Revolving Loans and Competitive Bid Loans);
(iv) fourth, to pay or prepay principal of Loans and Letters of Credit (ratably,
in respect of Revolving Loans, Competitive Bid Loans and Letters of Credit); (v)
fifth, to provide cash collateral in respect of Letters of Credit; and (vi)
sixth, to the ratable payment of all other Obligations.

          SECTION 2.20.  SHARING OF SETOFFS.  Each Lender agrees that if it
shall, through the exercise of a right of banker's lien, setoff or counterclaim
against the Borrower, or pursuant to a secured claim under Section 506 of Title
11 of the United States Code or other security or

<PAGE>

interest arising from, or in lieu of, such secured claim, received by such
Lender under any applicable bankruptcy, insolvency or other similar law or
otherwise (except pursuant to SECTION 2.24 or 9.04), or by any other means,
obtain payment (voluntary or involuntary) in respect of any Loan or Loans
(which, for purposes of this SECTION 2.20, shall include reimbursement
obligations with respect to LC Disbursements) as a result of which the unpaid
principal portion of its Loans shall be proportionately less than the unpaid
principal portion of the Loans of any other Lender, it shall be deemed
simultaneously to have purchased from such other Lender at face value, and shall
promptly pay to such other Lender the purchase price for, a participation in the
Loans of such other Lender, so that the aggregate unpaid principal amount of the
Loans and participations in Loans held by each Lender shall be in the same
proportion to the aggregate unpaid principal amount of all Loans then
outstanding as the principal amount of its Loans prior to such exercise of
banker's lien, setoff or counterclaim or other event was to the principal amount
of all Loans outstanding prior to such exercise of banker's lien, setoff or
counterclaim or other event; PROVIDED, HOWEVER, that, if any such purchase or
purchases or adjustments shall be made pursuant to this SECTION 2.20 and the
payment giving rise thereto shall thereafter be recovered, such purchase or
purchases or adjustments shall be rescinded to the extent of such recovery and
the purchase price or prices or adjustment restored without interest.  The
Borrower expressly consents to the foregoing arrangements and agrees that any
Lender holding a participation in a Loan deemed to have been so purchased may
exercise any and all rights of banker's lien, setoff or counterclaim with
respect to any and all moneys owing by the Borrower to such Lender by reason
thereof as fully as if such Lender had made a Loan directly to the Borrower in
the amount of such participation.

          SECTION 2.21.  PAYMENTS.  (a)  The Borrower shall make each payment
(including principal of or interest on the Loans, any Fees other than Issuing
Bank Fees or other amounts) hereunder and under any other Loan Document not
later than 12:00 noon, New York City time, on the date when due in dollars to
the Agent at its offices at 270 Park Avenue, New York, New York, in immediately
available funds.  Any payment received after 12:00 noon, New York City time, on
any date shall be deemed to have been received on the next succeeding Business
Day.

          (b)  Whenever any payment (including principal of or interest on any
Loans or any Fees or other amounts) hereunder or under any other Loan Document
shall become due, or otherwise would occur, on a day that is not a Business Day,
such payment may be made on the next succeeding Business Day, and such extension
of time shall in such case be included in the computation of interest or Fees,
if applicable, unless, in the case of a Eurodollar Loan only, such next
succeeding Business Day would fall in the next calendar month, in which case
such payment shall be made on the next preceding Business Day.

          SECTION 2.22.  TAXES.  (a) Any and all payments by the Borrower
hereunder shall be made, in accordance with SECTION 2.21, free and clear of and
without deduction for any and all present or future taxes, levies, imposts,
deductions, charges or withholdings, and all liabilities with respect thereto,
EXCLUDING (I) taxes imposed on the net income of the Agent, any Issuing Bank or
any Lender (or any transferee or assignee thereof that is permitted by SECTION
9.04, including a participation holder (any such entity being called a
"TRANSFEREE")), (ii) franchise or similar taxes imposed on the Agent, any
Issuing Bank or any Lender (or Transferee) by the United States of America or
any jurisdiction under the laws of which the Agent, such Issuing Bank or any
such Lender (or Transferee) is organized or in which the applicable lending
office is situated, or subject to such tax other than solely as a result of the
transactions provided for herein or any political subdivision thereof and (iii)
all taxes not imposed by the United States of America, the states or a political
subdivision thereof (all such nonexcluded taxes, levies, imposts, deductions,
charges, withholdings and liabilities being hereinafter referred to as "TAXES").
For purposes of this provision, taxes imposed on net income include United
States of America withholding taxes imposed upon the payment of interest unless
such taxes are imposed as a result of a change in the laws, treaties,
regulations or interpretations in existence

<PAGE>

on the Closing Date.  If the Borrower shall be required by law to deduct any
Taxes from or in respect of any sum payable hereunder to the Lenders (or any
Transferee), any Issuing Bank or the Agent, (i) the sum payable shall be
increased by the amount necessary so that after making all required deductions
(including deductions applicable to additional sums payable under this SECTION
2.22) such Lender (or Transferee), such Issuing Bank or the Agent (as the case
may be) shall receive an amount equal to the sum it would have received had no
such deductions been made, (ii) the Borrower shall make such deductions and
(iii) the Borrower shall pay the full amount deducted to the relevant taxing
authority or other Governmental Authority in accordance with applicable law;
PROVIDED, HOWEVER, that no Transferee of any Lender shall be entitled to receive
any greater payment under this PARAGRAPH (a) than such Lender would have been
entitled to receive with respect to the rights assigned, participated or
otherwise transferred.

          (b)  In addition, the Borrower agrees to pay any present or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies which arise from any payment made hereunder or from the
execution, delivery or registration of, or otherwise with respect to, this
Agreement or any other Loan Document (hereinafter referred to as "OTHER TAXES").

          (c)  The Borrower will indemnify each Lender (or Transferee), the
Agent and each Issuing Bank for the full amount of Taxes and Other Taxes paid by
such Lender (or Transferee), the Agent or such Issuing Bank as the case may be,
and any liability (including penalties, interest and expenses) arising therefrom
or with respect thereto, whether or not such Taxes or Other Taxes were correctly
or legally asserted by the relevant taxing authority or other Governmental
Authority.  Such indemnification shall be made within 30 Business Days after the
date any Lender (or Transferee), the Agent or any Issuing Bank, as the case may
be, makes written demand therefor.  If a Lender (or Transferee), the Agent or an
Issuing Bank shall become aware that it is entitled to receive a refund in
respect of Taxes or Other Taxes as to which it has been indemnified by the
Borrower pursuant to this SECTION 2.22 or a credit in respect of any Taxes or
Other Taxes paid by the Borrower pursuant to this SECTION 2.22 against taxes it
would otherwise have owed that are not Taxes or Other Taxes, it shall promptly
notify the Borrower of the availability of such refund or credit and shall apply
for such refund or credit at the Borrower's expense.  If any Lender (or
Transferee), the Agent or any Issuing Bank receives a refund or it becomes
entitled to take a credit in respect of any Taxes or Other Taxes as to which it
has been indemnified by the Borrower pursuant to this SECTION 2.22, it shall
promptly notify the Borrower of such refund or credit and shall promptly repay
such refund or pay the amount of such credit, as the case may be, to the
Borrower (to the extent of amounts that have been paid by the Borrower under
this SECTION 2.22 with respect to such refund or credit), net of all
out-of-pocket expenses of such Lender, the Agent or such Issuing Bank; PROVIDED
that the Borrower, upon the request of such Lender (or Transferee), the Agent or
such Issuing Bank agrees to return such refund or the amount of such credit
(plus penalties, interest or other charges) to such Lender (or Transferee), the
Agent or such Issuing Bank in the event such Lender (or Transferee), the Agent
or such Issuing Bank is required to repay such refund or is prohibited from
taking such credit against taxes that are not Taxes or Other Taxes.  Nothing
contained in this PARAGRAPH (c) shall require any Lender (or Transferee), the
Agent or any Issuing Bank to make available any of its tax returns (or any other
information relating to its taxes which it deems to be confidential).

          (d)  Within 30 Business Days after the date of any payment of Taxes or
Other Taxes withheld by the Borrower in respect of any payment to any Lender (or
Transferee), the Agent or any Issuing Bank, the Borrower will furnish to the
Agent, at its address referred to in SECTION 9.01, the original or a certified
copy of a receipt evidencing payment thereof to the extent that the relevant
taxing authority delivers such receipts.

<PAGE>

          (e)  Without prejudice to the survival of any other agreement
contained herein, the agreements and obligations contained in this SECTION 2.22
shall survive the payment in full of the Obligations hereunder.

          (f)  Each Lender and Issuing Bank represents to the Agent and the
Borrower that under applicable laws, treaties, regulations and interpretations
in existence on the Closing Date, no Taxes imposed by the United States of
America will be required to be withheld with respect to interest on the Loans.
Each Lender, the Agent and each Issuing Bank that is organized under the laws of
a jurisdiction outside the United States of America shall, on the Closing Date
and, if legally able to do so, at the beginning of each of its tax years
thereafter, deliver to the Borrower such certificates, documents or other
evidence, as required by the Internal Revenue Code or Treasury Regulations
issued pursuant thereto, including Internal Revenue Service Form 1001 or Form
4224 and any other certificate or statement of exemption required by Treasury
Regulation Section 1.1441-1, 1.1441-4 or 1.1441-6(c) or any subsequent version
thereof or successors thereto, properly completed and duly executed by such
Lender (or Transferee), the Agent or such Issuing Bank establishing that
payments made pursuant to this Agreement to such Lender (i) are not subject to
United States Federal withholding tax under the Internal Revenue Code because
such payment is effectively connected with the conduct by such Lender (or
Transferee), the Agent or such Issuing Bank of a trade or business in the United
States of America or (ii) are totally exempt from United States Federal
withholding tax, or are subject to a rate of such tax that has been reduced to
zero under a provision of an applicable tax treaty.  Unless the Borrower and the
Agent have received forms or other documents satisfactory to them indicating
that such payments hereunder are not subject to United States Federal
withholding tax or are subject to such tax at a rate reduced by an applicable
tax treaty, the Borrower or the Agent shall withhold taxes from such payments at
the applicable statutory rate.

          (g)  The Borrower shall not be required to pay any additional amounts
to any Lender (or Transferee), the Agent or any Issuing Bank in respect of
United States Federal withholding tax pursuant to PARAGRAPH (a) above if the
obligation to pay such additional amounts does not result from a change in laws,
treaties, regulations or interpretations in existence on the Closing Date.  Thus
the Borrower shall not reimburse for Taxes or Other Taxes arising from a failure
by the Lender (or Transferee), the Agent or such Issuing Bank (if required to do
so) to comply with the provisions of PARAGRAPH (f) above or from a transfer of
the Loans to another Applicable Lending Office; PROVIDED, HOWEVER, that the
Borrower shall be required to pay those amounts to any Lender (or Transferee),
the Agent or any Issuing Bank that it was required to pay hereunder prior to the
failure of such Lender (or Transferee), the Agent or such Issuing Bank to comply
with the provisions of PARAGRAPH (f).

          SECTION 2.23.  DUTY TO MITIGATE ADDITIONAL COSTS, REDUCTIONS IN RATE
OF RETURN AND TAXES.  Any Lender (or Transferee), the Agent or any Issuing Bank
claiming any amounts pursuant to SECTION 2.16 or 2.22 shall use reasonable
efforts (consistent with legal and regulatory restrictions) to avoid any costs,
reductions, Taxes or Other Taxes in respect of which such amounts are claimed,
including the filing of any certificate or document reasonably requested by the
Borrower or the changing of the jurisdiction of its lending office if such
efforts would avoid the need for or reduce the amount of any such amounts which
would thereafter accrue and would not, in the sole determination of such Lender
(or Transferee), the Agent or such Issuing Bank, result in any additional costs,
expenses or risks to such Lender (or Transferee), the Agent or such Issuing Bank
or would be otherwise disadvantageous to such Lender (or Transferee), the Agent
or such Issuing Bank.

          SECTION 2.24.  ASSIGNMENT OF COMMITMENTS UNDER CERTAIN CIRCUMSTANCES.

          In the event a Lender (an "AFFECTED LENDER") shall have: (i) failed to
either fund its Pro Rata Share of any Revolving Loan Borrowing

<PAGE>

requested by the Borrower which such Lender is obligated to fund under the terms
of SECTION 2.03 or its Competitive Bid Loan which such Lender is obligated to
fund under the terms of SECTION 2.04, and in either case such failure has not
been cured within five (5) Business Days, (ii) failed to fund its Pro Rata Share
of a payment to the Agent on behalf of an Issuing Bank which such Lender is
obligated to fund under the terms of SECTION 2.15 and such failure has not been
cured within five (5) Business Days, (iii) either repudiated its obligations
under this Agreement or failed to reaffirm such obligations in writing within
five (5) Business Days of a written request therefor from the Agent or any
Issuing Bank, (iv) delivered to the Borrower a notice described in the last
sentence of this SECTION 2.24, or (v) made demand for additional amounts
pursuant to SECTION 2.16 or 2.22, as a result of any condition described in any
such Section, then, unless such Affected Lender has theretofore taken steps to
remove or cure, and has removed or cured within five (5) Business Days, such
failure or the circumstances described in such notice or the conditions creating
the cause for such demand for such additional amounts, as the case may be, the
Borrower may require the Affected Lender to transfer and assign without recourse
(in accordance with and subject to the restrictions contained in SECTION 9.04)
all its interests, rights and obligations under this Agreement to a bank
designated by the Borrower and which is reasonably acceptable to the Agent (such
bank being herein called a "REPLACEMENT LENDER"); PROVIDED, that (i) no such
assignment shall conflict with any law, rule or regulation or order of any
Governmental Authority and (ii) the Replacement Lender shall pay to the Affected
Lender in immediately available funds on the date of such termination or
assignment the principal of and interest accrued to the date of payment on the
Loans made by it hereunder and all other amounts accrued for its account or owed
to it hereunder.  Each Lender agrees to use its best efforts to notify the
Borrower as promptly as practicable upon such Lender's becoming aware that
circumstances exist which would cause the Borrower to become obligated to pay
additional amounts to such Lender pursuant to SECTION 2.16 or 2.22; PROVIDED,
that the failure by any Lender to give such notice shall not affect the
obligations of the Borrower under such Sections.


                  ARTICLE III.  REPRESENTATIONS AND WARRANTIES

on such returns, or have been assessed by any Governmental Authority, as being
due and payable, have been paid when due and payable, except such taxes, if any,
that are reserved against in accordance with GAAP, such taxes as are being
contested in good faith by appropriate proceedings or such taxes the failure to
make payment of which when due and payable would not have, in the aggregate, a
Material Adverse Effect; and (ii) the Borrower has no knowledge of any proposed
tax assessment against the Borrower or any of its Subsidiaries that would have a

as a whole) furnished by or on behalf of the Borrower and/or its Subsidiaries to
the Agent and the Lenders, do not contain any material misstatement of fact or

contained therein, in light of the circumstances under which they were made, not
misleading, and (ii) neither the Borrower nor any of its Subsidiaries has inten-
tionally withheld any fact known to it which would have a Material Adverse
Effect which has not been set forth or referred to in this Agreement or the

has been identified as potentially responsible for, or is subject to
investigation by any Governmental Authority relating to, the Release or
threatened Release of any Contaminant into the environment; (iv) notice that any
Property of the Borrower or any of its domestic Subsidiaries is subject to an
Environmental Lien; (iv) notice of violation to the Borrower or any of its
domestic Subsidiaries or awareness by the Borrower or any of its domestic
Subsidiaries of a condition which might reasonably result in a notice of

administrative proceeding alleging a violation of any environmental Requirement
of Law; (vi) commencement of any judicial proceeding alleging a violation of any
health or safety Requirement of Law; or (vii) any proposed acquisition of stock,
assets, real estate, or leasing of Property, or any other action by the Borrower

have a Material Adverse Effect; and

<PAGE>

          (b)  neither the Borrower nor any of its Subsidiaries have made any
filing or report with any Governmental Authority with respect to (i) the
violation of any environmental, health or safety Requirement of Law, (ii) any
unpermitted Release or threatened Release of a Contaminant or (iii) any unsafe
or unhealthful condition at any Property of the Borrower or any of its
Subsidiaries, any of which would have a Material Adverse Effect.

          SECTION 3.14.  ERISA.  Neither the Borrower nor any ERISA Affiliate
maintains or contributes to any Benefit Plan other than a Benefit Plan listed on
SCHEDULE 3.14 annexed hereto.  Except as otherwise provided on SCHEDULE 3.14,
each Plan which is intended to be a qualified plan has been determined by the
IRS to be qualified under Section 401(a) of the Internal Revenue Code, and each
trust related to any such Plan has been determined to be exempt from federal
income tax under Section 501(a) of the Internal Revenue Code prior to its
amendment by the Tax Reform Act of 1986, and such Plan and trust are being
operated in all material respects in compliance with the Tax Reform Act of 1986
and all other amendments to the Internal Revenue Code and ERISA as interpreted
by the regulations promulgated thereunder.  Except as otherwise provided on
SCHEDULE 3.14, neither the Borrower nor any ERISA Affiliate maintains or
contributes to any employee welfare benefit plan within the meaning of Section
3(1) of ERISA which provides lifetime benefits to retirees.  The Borrower and
all of its ERISA Affiliates are in compliance in all material respects with the
responsibilities, obligations and duties imposed on them by ERISA or regulations
promulgated thereunder with respect to all Plans.  No accumulated funding
deficiency (as defined in Section 302(a)(2) of ERISA and Section 412(a) of the
Internal Revenue Code) exists with respect to any Benefit Plan.  Except as
otherwise provided on SCHEDULE 3.14, neither the Borrower nor any ERISA
Affiliate nor any fiduciary of any Plan which is not a Multiemployer Plan
(i) has engaged in a nonexempt "prohibited transaction" described in Sections
406 and 408 of ERISA or Section 4975 of the Internal Revenue Code or (ii) has
taken any action which would constitute or result in a Termination Event with
respect to any Plan which would result in a material liability to the Borrower.
Neither the Borrower nor any ERISA Affiliate has incurred any material liability
to the PBGC that has not been paid within the applicable period permitted by
law.  Schedule B to the most recent annual report filed with the Internal
Revenue Service with respect to each Benefit Plan and furnished to the Lenders
is complete and accurate.  Except as provided on SCHEDULE 3.14, since the date
of each such Schedule B, there has been no material adverse change in the
funding status or financial condition of the Benefit Plan relating to such
Schedule B which would result in a Material Adverse Effect.  Neither the
Borrower nor any ERISA Affiliate has failed to make a required contribution or
payment to a Multiemployer Plan on or before the required due date for such
contribution or installment which failure would have a Material Adverse Effect.
Neither the Borrower nor any ERISA Affiliate has failed to make a required
installment under subsection (m) of Section 412 of the Internal Revenue Code or
any other payment required under Section 412 of the Internal Revenue Code on or
before the due date for such installment or other payment, which failure would
have a Material Adverse Effect.  Neither the Borrower nor any ERISA Affiliate is
required to provide security to a Plan under Section 401(a)(29) of the Internal
Revenue Code due to a Benefit Plan amendment that results in an increase in
current liability for the plan year.

          SECTION 3.15.  ASSETS AND PROPERTIES.  As of the Closing Date: (i) the
Borrower and each of its Subsidiaries has good and marketable title to all of
its assets (tangible and intangible) owned by it, and all such assets are free
and clear of all Liens except as specifically permitted or contemplated by the
terms and provisions of this Agreement; and (ii) substantially all of the assets
and properties owned by, leased to or used by the Borrower and/or each such
Subsidiary are in adequate operating condition and repair, ordinary wear and
tear excepted, are free and clear of any known defects except such defects as do
not substantially interfere with the continued use thereof in the conduct of
normal operations, and are able to serve the function for which they are
currently being used, except in each case where the failure of such asset to
meet such requirements would not have a Material Adverse Effect.

<PAGE>

          SECTION 3.16.  AGREEMENTS.  Neither the Borrower nor any of its
Subsidiaries is in default in any manner under any provision of any indenture or
other agreement or instrument evidencing Debt, or any other material agreement
or instrument to which it is a party or by which it or any of its properties or
assets is or may be bound, where such default would result in a Material Adverse
Effect.

          SECTION 3.18.  FINANCIAL STATEMENTS.  The Borrower has heretofore
furnished to the Lenders consolidated financial statements (i) as of December
31, 1994, audited by and accompanied by the opinion of Arthur Andersen & Co. or
other independent certified public accountants of recognized national standing
satisfactory to the Agent and (ii) as of March 31, 1995.  Such financial
statements present fairly in all material respects the financial condition and
results of operations of the Borrower and each of its consolidated Subsidiaries
and as of such dates and for such periods.  Such balance sheets and the notes
thereto disclose all material liabilities, direct or contingent, of the Borrower
and its consolidated Subsidiaries (including the Borrower) as of the dates
thereof that are required to be disclosed under GAAP.  Such financial statements
were prepared in accordance with GAAP applied on a consistent basis, except as
set forth in the notes to such financial statements.  There has been no material
adverse change in the business, assets, operations or financial condition of the
Borrower and its Subsidiaries since December 31, 1994.

or any of its Material Subsidiaries shall have an order for relief entered with
respect to it or commence a voluntary case under any applicable bankruptcy,

or any of the Material Subsidiaries adopts any resolution or otherwise

not denied coverage with respect to such money judgment), writ or warrant of
attachment, or similar process involving in any case an amount in excess of
twenty-five million dollars ($25,000,000) shall be entered or filed against the

than in connection with the release of the Collateral Trustee's Lien on the
capital stock of the domestic Material Subsidiaries as contemplated by SECTION
9.07, (I) any Collateral Document ceases to be in full force and effect or any
Lien intended to be created thereby ceases to be or is not valid and perfected;

contemplated by this Agreement or any Collateral Document shall, at any time, be

<PAGE>

Affiliates and "Associates" (as defined below) shall directly or indirectly
beneficially own in the aggregate 50% or more of the common stock then
outstanding.  For purposes of this SECTION 7.01(l), (I) "beneficial ownership"
shall be determined in accordance with Rule 13d-3 (or any successor rule) of the
Commission under the Securities Exchange Act; PROVIDED, HOWEVER, that any
employee benefit plan of the Borrower or a trustee or other Person holding
common stock for or pursuant to the terms of any such plan shall not be deemed

such plan has the right to direct the trustee or other Person (A) to vote the
common stock held by such plan for his or her benefit and (B) to tender such
common stock in the event of a tender offer for common stock; and (ii)
"ASSOCIATE" shall mean, with respect to any Person, (A) an officer, employee or

in a similar fiduciary capacity, or (c) a relative or spouse of such Person, or
a relative of such spouse, who has the same home as such Person.

          (m)  ERISA LIABILITIES.  Any Termination Event occurs which will or is
reasonably likely to subject either the Borrower or an ERISA Affiliate to a
liability which would have a Material Adverse Effect, or, the plan administrator
of any Benefit Plan applies for and receives approval under Section 412(d) of
the Internal Revenue Code for a waiver of the minimum funding standards of
Section 412(a) of the Internal Revenue Code and the business hardship upon which
the Section 412(d) waiver was based will or is reasonably likely to subject
either the Borrower or an ERISA Affiliate to a liability which would have a
Material Adverse Effect.

          (n)  ENVIRONMENTAL LIABILITIES.  The Borrower or any of its
Subsidiaries shall become subject to any Liabilities and Costs arising out of or
related to (a) the Release or threatened Release at any location of any
Contaminant into the environment, or any Remedial Action in response thereto, or
(b) any violation of any environmental, health or safety Requirements of Law,
which Liabilities and Costs, individually or in the aggregate, would have a
Material Adverse Effect.  "REMEDIAL ACTION" shall mean any action required to
(I) clean up, remove or treat or in any other way address Contaminants in the
indoor or outdoor environment; (ii) prevent a Release or threat of Release or
minimize the further Release of Contaminants so they do not migrate or endanger
or seriously threaten to endanger public health or welfare or the indoor or
outdoor environment; or (iii) perform pre-remedial studies and investigations or
post-remedial monitoring and care.

An Event of Default shall be deemed "continuing" until cured or waived in
writing in accordance with SECTION 9.09.

          7.02.  RIGHTS AND REMEDIES.

          (a)  ACCELERATION.  Upon the occurrence of any Event of Default
described in the foregoing SECTION 7.01(g) or 7.01(h), all Commitments shall
automatically and immediately terminate and the unpaid principal amount of and
any and all accrued interest on the Loans, all Obligations in respect of LC
Exposure and all accrued Commitment Fees and all other fees payable hereunder
shall automatically become immediately due and payable by the Borrower, with all
additional interest from time to time accrued thereon and without presentment,
demand, or protest or other requirements of any kind (including, without
limitation, valuation or appraisal, diligence, presentment or notice of intent
to demand or accelerate or of acceleration), all of which are hereby expressly
waived by the Borrower, and the obligation of each Lender to make any Revolving
Loan hereunder or each Issuing Bank to issue or each Lender to participate in
any additional Letter of Credit shall thereupon terminate; and upon the
occurrence and during the continuance of any other Event of Default, by written
notice to the Borrower, the Agent shall, at the request, or may with the
consent, of the Requisite Lenders, (I) declare that the Commitments are termi-
nated, whereupon the Commitments and the obligation of each Lender to make any
Revolving Loan hereunder, or each Issuing Bank to issue or each Lender to
participate in any additional Letter of Credit shall immediately

<PAGE>

terminate, and/or (ii) declare the unpaid principal amount of and any and all
accrued and unpaid interest on the Loans to be, and the same shall thereupon be,
immediately due and payable with all additional interest from time to time
accrued thereon and without presentment, demand, or protest or other
requirements of any kind (including, without limitation, valuation or appraisal,
diligence, presentment or notice of intent to demand or accelerate or of
acceleration), all of which are hereby expressly waived by the Borrower.

          (b)  CASH COLLATERAL.  In addition, following the occurrence of any
Event of Default, the Borrower shall, upon the request of an Issuing Bank,
promptly deposit with the Agent for the benefit of the Lenders and such Issuing
Bank, in connection with an extension of the expiry date of any Letters of
Credit issued by such Issuing Bank, cash or Cash Equivalents in an amount up to
the greatest amount for which such Letters of Credit may be drawn.  Such deposit
shall be held by the Agent for the benefit of the Lenders and the Issuing Banks,
as security for, and to provide for the payment of, LC Obligations.  The
Borrower hereby grants to the Agent, for the benefit of the Lenders and the
Issuing Banks, a lien and security interest in all such sums held by the Agent.

          (c)  RESCISSION.  If at any time after acceleration of the maturity of
the Loans, the Borrower shall pay all arrears of interest and all payments on
account of principal of the Loans and LC Obligations which shall have become due
otherwise than by acceleration (with interest on principal and, to the extent
permitted by law, on overdue interest, at the rates specified in this Agreement)
and all Events of Default and Potential Events of Default (other than nonpayment
of principal of and accrued interest on the Loans and the Notes and with respect
to Letters of Credit, due and payable solely by virtue of acceleration) shall be
remedied or waived pursuant to SECTION 9.09, then by written notice to the
Borrower, the Requisite Lenders may elect, in the sole discretion of such
Requisite Lenders, to rescind and annul the acceleration and its consequences;
but such action shall not affect any subsequent Event of Default or Potential
Event of Default or impair any right or remedy consequent thereon.  The
provisions of the preceding sentence are intended merely to bind the Lenders to
a decision which may be made at the election of the Requisite Lenders; they are
not intended to benefit the Borrower and do not give the Borrower the right to
require the Lenders to rescind or annul any acceleration hereunder, even if the
conditions set forth herein are met.


                            ARTICLE VIII.  THE AGENT

          SECTION 8.01.  APPOINTMENT.  In order to expedite the transactions
contemplated by this Agreement, Chemical Bank is hereby appointed to act as
Agent on behalf of the Lenders and the Issuing Banks.  Each of the Lenders and
the Issuing Banks hereby irrevocably authorizes the Agent to take such actions
on its behalf and to exercise such powers as are specifically delegated to the
Agent by the terms and provisions hereof and of the other Loan Documents,
together with such actions and powers as are reasonably incidental thereto.  The
Agent is hereby expressly authorized by the Lenders and the Issuing Banks,
without hereby limiting any implied authority, and the Agent hereby agrees, (a)
to receive on behalf of the Lenders and the Issuing Banks all payments of
principal of and interest on the Loans and the LC Disbursements and all other
amounts due to the Lenders and the Issuing Banks hereunder, and promptly to
distribute to each Lender and Issuing Bank its proper share of each payment so
received; (b) to give notice on behalf of each of the Lenders to the Borrower of
any Event of Default specified in this Agreement of which the Agent has actual
knowledge acquired in connection with its agency hereunder; and (c) to
distribute to each Lender and Issuing Bank copies of all notices, financial
statements and other materials delivered by the Borrower pursuant to this
Agreement as received by the Agent.

          SECTION 8.02.  NATURE OF DUTIES.  The Agent shall not have any duties
or responsibilities except those expressly set forth in this Agreement or in the
other Loan Documents.  The Agent's duties shall be mechanical and

<PAGE>

administrative in nature.  The Agent shall not have by reason of this Agreement
a fiduciary relationship in respect of any Lender or any Issuing Bank.  Nothing
in this Agreement or any of the other Loan Documents, expressed or implied, is
intended to or shall be construed to impose upon the Agent any obligations in
respect of this Agreement or any of the other Loan Documents except as expressly
set forth herein or therein.  With respect to the taking or refraining from
taking any action hereunder, if the Agent seeks the consent or approval of the
Requisite Lenders, the Agent shall send notice thereof to each Lender.  The
Agent shall promptly notify each Lender at any time that the Requisite Lenders
or, where expressly required, all of the Lenders, have instructed the Agent to
act or refrain from acting pursuant hereto.

          SECTION 8.03.  RIGHTS, EXCULPATION, ETC.  Neither the Agent nor any of
its directors, officers, employees, Affiliates or agents shall be liable as such
for any action taken or omitted by any of them except for its or his own gross
negligence or willful misconduct, or be responsible for any statement, warranty
or representation herein or the contents of any document delivered in connection
herewith, or be required to ascertain or to make any inquiry concerning the
performance or observance by the Borrower of any of the terms, conditions,
covenants or agreements contained in any Loan Document.  The Agent shall not be
responsible to the Lenders for the due execution, genuineness, validity,
enforceability or effectiveness of this Agreement or any other Loan Documents or
other instruments or agreements.  The Agent shall in all cases be fully
protected in acting, or refraining from acting, in accordance with written
instructions signed by the Requisite Lenders or all of the Lenders, as
appropriate, and, except as otherwise specifically provided herein, such
instructions and any action or inaction pursuant thereto shall be binding on all
the Lenders and the Issuing Banks.  The Agent shall, in the absence of knowledge
to the contrary, be entitled to rely on any instrument or document believed by
it in good faith to be genuine and correct and to have been signed or sent by
the proper Person or Persons.  Neither the Agent nor any of its directors,
officers, employees or agents shall have any responsibility to the Borrower on
account of the failure of or delay in performance or breach by any Lender or
Issuing Bank of any of its obligations hereunder or to any Lender or Issuing
Bank on account of the failure of or delay in performance or breach by any other
Lender or Issuing Bank or the Borrower of any of their respective obligations
hereunder or under any other Loan Document or in connection herewith or
therewith.  The Agent may execute any and all duties hereunder by or through
agents or employees and shall be entitled to rely upon the advice of legal
counsel selected by it with respect to all matters arising hereunder and shall
not be liable for any action taken or suffered in good faith by it in accordance
with the advice of such counsel.

          The Lenders and the Issuing Banks hereby acknowledge that the Agent
shall be under no duty to take any discretionary action permitted to be taken by
it pursuant to the provisions of this Agreement unless it shall be requested in
writing to do so by the Requisite Lenders.

          SECTION 8.04.  SUCCESSOR AGENT; RESIGNATION OF THE AGENT.  Subject to
the appointment and acceptance of a successor Agent as provided below, the Agent
may resign at any time by notifying the Lenders, the Issuing Banks and the
Borrower.  Upon any such resignation, the Requisite Lenders shall have the right
to appoint a successor acceptable to the Borrower.  If no successor shall have
been so appointed by the Requisite Lenders and shall have accepted such
appointment within 30 days after the retiring Agent gives notice of its
resignation, then the retiring Agent may, on behalf of the Lenders, appoint a
successor Agent which shall be a United States of America bank with an office in
New York, New York, having a combined capital and surplus of at least
$500,000,000 or an Affiliate of any such bank, and which shall be reasonably
acceptable to the Borrower.  Upon the acceptance of any appointment as Agent
hereunder by a successor bank, such successor shall succeed to and become vested
with all the rights, powers, privileges and duties of the retiring Agent and the
retiring Agent shall be discharged from its duties and obligations hereunder.
After the Agent's resignation hereunder, the provisions of this ARTICLE and
SECTION 9.05 shall continue in effect for its

<PAGE>

benefit in respect of any actions taken or omitted to be taken by it while it
was acting as Agent.

          SECTION 8.05.  THE AGENT INDIVIDUALLY.  With respect to the Loans made
by it hereunder, Chemical Bank, in its individual capacity and not as Agent,
shall have the same rights and powers as any other Lender and may exercise the
same as though it was not the Agent, and Chemical Bank and its Affiliates may
accept deposits from, lend money to and generally engage in any kind of business
with the Borrower, or any Subsidiary or any other Affiliate thereof, as if it
was not the Agent.

          SECTION 8.06.  INDEMNIFICATION.  Each Lender agrees (I) to reimburse
the Agent, on demand, in the amount of its Pro Rata Share of any expenses
incurred for the benefit of the Lenders or the Issuing Banks by the Agent,
including counsel fees and compensation of agents and employees paid for
services rendered on behalf of the Lenders or the Issuing Banks, which shall not
have been reimbursed by the Borrower and (ii) to indemnify and hold harmless the
Agent and any of its directors, officers, employees or agents, on demand, in the
amount of such Pro Rata Share, from and against any and all liabilities, taxes,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever which may be imposed
on, incurred by or asserted against it in its capacity as the Agent or any of
them in any way relating to or arising out of this Agreement or any other Loan
Document or any action taken or omitted by it or any of them under this
Agreement or any other Loan Document, to the extent the same shall not have been
reimbursed by the Borrower; PROVIDED that no Lender shall be liable to the Agent
under CLAUSE (I) or (ii) above for any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements resulting from the gross negligence or willful misconduct of the
Agent or any of its directors, officers, employees or agents.

          SECTION 8.07.  INDEPENDENT CREDIT ANALYSIS.  Each Lender and Issuing
Bank acknowledges that it has, independently and without reliance upon the Agent
or any other Lender or Issuing Bank and based on such documents and information
as it has deemed appropriate, made its own credit analysis and decision to enter
into this Agreement.  Each Lender and Issuing Bank also acknowledges that it
will, independently and without reliance upon the Agent or any other Lender or
Issuing Bank and based on such documents and information as it shall from time
to time deem appropriate, make its own credit analysis and decision to make
Loans hereunder from and after the Closing Date and continue to make its own
decisions in taking or not taking action under or based upon this Agreement or
any other Loan Document, any related agreement or any document furnished
hereunder or thereunder.

          SECTION 8.08.  RELATIONS AMONG LENDERS.  Each Lender and each Issuing
Bank agrees that it will not take any action, nor institute any actions or
proceedings, against the Borrower with respect to this Agreement or any other
Loan Document without the prior written consent of the Requisite Lenders.

respective successors and assigns, except that the Borrower shall not have the

          (b)  Each Lender may assign to one or more Eligible Assignees all or a
percentage of such assigning Lender's interests, rights and obligations under
this Agreement and the other Loan Documents (including all or a portion of the
Loans owing to it, the Notes held by it and its Commitments); PROVIDED, HOWEVER,
that (I) except in the case of an assignment to a Lender or an Affiliate of a

written consent to such assignment (which consent of the Agent, the Borrower and
the Issuing Banks shall not be unreasonably withheld), (ii) the aggregate amount

Commitments, (iii) the parties to each such assignment shall execute and deliver

and after the effective date specified in each Assignment and Acceptance, which
effective date shall be at least five Business Days (except as otherwise agreed
by the assignor, the assignee and the Agent) after the execution thereof, (A)
the assignee thereunder shall be a party hereto and, to the extent of the
interest assigned by such Assignment and Acceptance, have the rights and
obligations of a Lender under this Agreement and the other Loan Documents and
(B) the assigning Lender thereunder shall, to the extent of the interest
assigned by such Assignment and Acceptance, be released from its obligations
under this Agreement (and, in the case of an Assignment and Acceptance covering
all or the remaining portion of an assigning Lender's rights and obligations
under this Agreement, such Lender shall cease to be a party hereto but shall
continue to be entitled to the benefits of SECTIONS 2.16, 2.18, 2.22 and 9.05,
as well as to any interest and Fees accrued for its account and not yet paid).

          Notwithstanding the foregoing, any Lender assigning rights and
obligations under this Agreement may retain any Competitive Bid Loans made by it
outstanding at such time and in such case shall retain its rights hereunder in
respect of any Loans so retained until such Loans have been repaid in full in
accordance with this Agreement.

          (c)  By executing and delivering an Assignment and Acceptance, the
assigning Lender thereunder and the assignee thereunder shall be deemed to
confirm to and agree with each other and the other parties hereto as follows:
(I) such assigning Lender warrants that it is the legal and beneficial owner of
the interest being assigned thereby free and clear of any adverse claim and that
its Commitments and/or the outstanding balances of its Loans, in each case
without giving effect to assignments thereof which have not become effective,
are as set forth in such Assignment and Acceptance, (ii) except as set forth in
CLAUSE (I) above, such assigning Lender makes no representation or warranty and
assumes no responsibility with respect to any statements, warranties or
representations made in or in connection with this Agreement, any other Loan
Document, or any other instrument or document furnished pursuant hereto or
thereto, or the execution, legality, validity, enforceability, genuineness,
sufficiency or value of this Agreement, any other Loan Document or any other
instrument or document furnished pursuant hereto or thereto, or the financial
condition of the Borrower or any Subsidiary of the Borrower or the performance
or observance by the Borrower or any Subsidiary of the Borrower of any of its
obligations under this Agreement, any other Loan Document or any other
instrument or document furnished pursuant hereto or thereto; (iii) such assignee
represents and warrants that it is legally authorized to enter into such
Assignment and Acceptance and that it is an Eligible Assignee; (iv) such
assignee confirms that it has received a copy of this Agreement, together with
copies of the most recent financial statements delivered pursuant to SECTION
5.07 and such other documents and information as it has deemed appropriate to
make its own credit analysis and decision to enter into such Assignment and
Acceptance; (v) such assignee will independently and without reliance upon the
Agent, such assigning Lender or any other Lender and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit decisions in taking or not taking action under this Agreement; (vi) such
assignee appoints and authorizes the Agent to take such action as Agent on its
behalf and to exercise such powers under this Agreement as are delegated to the
Agent by the terms hereof, together with such powers as are reasonably
incidental thereto; and (vii) such assignee agrees that it will perform in
accordance with their terms all the obligations which by the terms of this
Agreement are required to be performed by it as a Lender.

          (d)  The Agent shall maintain at one of its offices in The City of New
York a copy of each Assignment and Acceptance delivered to it and a register for
the recordation of the names and addresses of the Lenders, and the Commitments
of, and principal amount of the Loans owing to, each Lender pursuant to the
terms hereof from time to time (the "REGISTER").  The entries in the Register
shall be conclusive in the absence of manifest error and the

<PAGE>

Borrower, the Agent and the Lenders may treat each Person whose name is recorded
in the Register pursuant to the terms hereof as a Lender hereunder for all
purposes of this Agreement.  The Register shall be available for inspection by
the Borrower and any Lender at any reasonable time and from time to time upon
reasonable prior notice.

          (e)  Upon its receipt of a duly completed Assignment and Acceptance
executed by an assigning Lender and an assignee, an Administrative Questionnaire
completed in respect of the assignee (unless the assignee shall already be a
Lender hereunder), the processing and recordation fee referred to in PARAGRAPH
(b) above and, if required, the written consent of the Borrower, the Agent, and
the Issuing Banks to such assignment, the Agent shall (I) accept such Assignment
and Acceptance, (ii) record the information contained therein in the Register
and (iii) give prompt notice thereof to the Borrower, the Lenders and the
Issuing Banks.

          (f) Upon the acceptance by the Agent of any Assignment and Acceptance,
the parties to such Assignment and Acceptance may at any time request that a new
Revolving Loan Note and a new Competitive Bid Note be issued to the Lender
assignee by (I) providing written notice of such request to the Agent and the
Borrower and (ii) delivering to the Borrower such assigning Lender's Revolving
Loan Note and Competitive Bid Note for cancellation and substitution; PROVIDED
that the Competitive Bid Note shall only be so delivered if the assignor is
assigning all of its Revolving Credit Commitment; PROVIDED, FURTHER, that if the
Lender is assigning all of its Revolving Credit Commitment, and such Lender is
retaining any outstanding Competitive Bid Loans, the Competitive Bid Note shall
be delivered when such Competitive Bid Loans have been paid in full.  With
respect to each such Note so delivered, promptly following receipt by the
Borrower of any such notice and such Note, and verification from the Agent that
the applicable Assignment and Acceptance shall have been accepted by the Agent,
the Borrower forthwith shall cause to be executed, and shall deliver to the
Lender assignee, a new Note to the order of the assignee and, if applicable, a
replacement Note to the order of the Lender assignor, and such Note or Notes
shall be in an aggregate principal amount equal to the aggregate principal
amount of the assigning Lender's surrendered Note issued by the Borrower
immediately prior to the acceptance by the Agent of the applicable Assignment
and Acceptance; PROVIDED, HOWEVER, that each Competitive Bid Note shall be in
the principal amount of the Aggregate Revolving Credit Commitments.  The
Borrower shall, immediately upon delivery of such new Note(s), cancel the
original Note or Notes delivered by the Lender assignor to the Borrower.

          (g)  Each Lender, without the consent of the Borrower, the Agent or
any Issuing Bank, may sell participations to one or more banks or other entities
in all or a portion of its rights and obligations under this Agreement
(including all or a portion of its Commitments and the Loans owing to it);
PROVIDED, HOWEVER, that (I) such Lender's obligations under this Agreement shall
remain unchanged, (ii) such Lender shall remain solely responsible to the other
parties hereto for the performance of such obligations, (iii) the participating
banks or other entities shall be entitled to the benefit of the cost protection
and indemnity provisions contained in SECTIONS 2.16, 2.18, 2.22 and 9.05 to the
same extent as if they were Lenders (except that no participant shall be
entitled to claim any amount greater than its pro rata share of the amount that
could have been claimed by the Lender from which it acquired its participation)
and (iv) the Borrower, the Agent, the Issuing Banks and the other Lenders shall
continue to deal solely and directly with such Lender in connection with such
Lender's rights and obligations under this Agreement, and such Lender shall
retain the sole right to enforce the obligations of the Borrower relating to the
Loans and to approve any amendment, modification or waiver of any provision of
this Agreement (other than amendments, modifications or waivers decreasing any
fees payable hereunder (other than Issuing Bank Fees) or the amount of principal
of or the rate at which interest is payable on the Loans or LC Disbursements,
extending the final maturity of the Loans or any date fixed for the payment of
interest on the Loans or LC Disbursements or any Fees (other than Issuing Bank
Fees) or extending the Commitments).

          (h)  Any Lender or participant may, in connection with any assignment
or participation or proposed assignment or participation pursuant to this
SECTION 9.04, disclose to the assignee or participant or proposed assignee or
participant any information relating to the Borrower and its Subsidiaries
furnished to such Lender by or on behalf of the Borrower; PROVIDED that, prior
to any such disclosure of information designated by the Borrower as
confidential, each such assignee or participant or proposed assignee or
participant shall execute an agreement substantially in the form of that
executed in connection with the syndication of the Revolving Credit Commitments
by those Lenders party hereto as of the Closing Date, whereby such assignee or
participant shall agree (subject to customary exceptions) to preserve the
confidentiality of such confidential information.

          (I)  Any Lender may at any time pledge or assign all or any portion of
its rights under this Agreement and the Notes issued to it to a Federal Reserve
Bank; PROVIDED that no such assignment shall release a Lender from any of its
obligations hereunder.

          (j)  The Borrower shall not assign or delegate any of its rights or
duties hereunder without the consent of each Lender.

          SECTION 9.05. EXPENSES; INDEMNITY.  (a)  The Borrower agrees to pay
all reasonable out-of-pocket expenses incurred by the Agent in connection with
the preparation of this Agreement and the other Loan Documents or in connection
with any amendments, modifications or waivers of the provisions hereof or
thereof requested by the Borrower or incurred by the Agent, any Issuing Bank or
any Lender following an Event of Default or Potential Event of Default in
connection with the enforcement or protection of their rights in connection with
this Agreement and the other Loan Documents or in connection with the Loans made
or Letters of Credit issued hereunder, including in each case the reasonable
fees, charges and disbursements of counsel for the Agent, and, in connection
with any such enforcement or protection, the reasonable fees, charges and
disbursements of any other counsel for the Agent, any Issuing Bank or any
Lender.  The Borrower further agrees that it shall indemnify the Agent, the
Issuing Banks and the Lenders from and hold them harmless against any
documentary taxes, assessments or charges made by any Governmental Authority by
reason of the execution and delivery or enforcement of this Agreement or any of
the other Loan Documents.

          (b)  The Borrower agrees to indemnify the Agent, each Issuing Bank,
each Lender and each of their respective directors, officers, employees,
Affiliates, attorneys and agents (each such Person being called an "INDEMNITEE")
against, and to hold each Indemnitee harmless from, any and all liabilities,
damages, obligations, losses, penalties, actions, judgments, suits, costs and
expenses which (if such liabilities, damages, obligations, losses, penalties,
actions, judgments, suits, costs and expenses arise in a judicial forum) are
found in a final judgment by a court of competent jurisdiction, including
reasonable counsel fees, charges and disbursements, incurred by or asserted
against any Indemnitee arising out of any third party claim, litigation,
investigation or proceeding (whether or not any Indemnitee shall be party
thereto) relating to, in any way connected with, or as a result of (I) the
execution or delivery of this Agreement or any other Loan Document or any
agreement or instrument contemplated hereby or thereby, or (ii) the use of the
Letters of Credit or the proceeds of the Loans (a "THIRD PARTY CLAIM"); PROVIDED
that such indemnity shall not, as to any Indemnitee, be available to the extent
that such liabilities, damages, obligations, losses, penalties, actions,
judgments, suits, costs and expenses are found in a final judgment by a court of
competent jurisdiction to have resulted from the gross negligence, bad faith or
willful misconduct of such Indemnitee; PROVIDED FURTHER that (A) each Indemnitee
shall promptly (but in any event within ten (10) Business Days) notify the
Borrower in writing upon becoming aware of the initiation of any Third Party
Claim against it, (B) the Borrower shall be entitled to participate in the
defense of any such Third Party Claim and, if the Borrower so chooses, to assume
the defense, at the Borrower's expense, of any such Third Party Claim with
counsel selected by the Borrower (it being understood that any Indemnitee shall
have the right to participate in such defense and

<PAGE>

employ counsel separate from the counsel employed by the Borrower, and that such
counsel shall be at the expense of such Indemnitee unless such Indemnitee shall
have been advised by counsel that there may be legal defenses available to it
that are inconsistent with or in addition to those available to the Borrower, in
which case such counsel shall be at the expense of the Borrower) and (c) no
Indemnitee shall settle any Third Party Claim without the prior written consent
of the Borrower (which consent shall not be unreasonably withheld).

          (c) None of the Agent, any Lender, any Issuing Bank, the Borrower or
any of their respective directors, officers, employees, Affiliates, attorneys
and agents shall be responsible or liable to any other party hereto or any other
Person or entity for consequential damages which may be alleged as a result of
the transactions contemplated hereby, except to the extent specifically set
forth in this Agreement.

          (d)  The provisions of this SECTION 9.05 shall remain operative and in
full force and effect regardless of the expiration of the term of this
Agreement, the consummation of the transactions contemplated hereby, the
repayment of any of the Loans, the invalidity or unenforceability of any term or
provision of this Agreement or any other Loan Document, or any investigation
made by or on behalf of the Agent, any Issuing Bank or any Lender.  All amounts
due under this SECTION 9.05 shall be payable within ten Business Days after
written demand therefor.

          SECTION 9.06.  RIGHT OF SETOFF.  If an Event of Default shall have
occurred and be continuing, each Lender is hereby authorized at any time and
from time to time, to the fullest extent permitted by law, to set off and apply
any and all deposits (general or special, time or demand, provisional or final)
at any time held and other indebtedness at any time owing by such Lender to or
for the credit or the account of the Borrower against any of and all the
Obligations now or hereafter existing under this Agreement and other Loan
Documents to such Lender, irrespective of whether or not such Lender shall have
made any demand under this Agreement or such other Loan Document and although
such obligations may be unmatured.  The rights of each Lender under this SECTION
9.06 are in addition to other rights and remedies (including other rights of
setoff) which such Lender may have.

          SECTION 9.07.  CONCERNING THE COLLATERAL DOCUMENTS; ACTIONS BY THE
LENDERS; TRUSTEE'S FEES; RELEASE OF COLLATERAL.  (a)  Each Lender and each
Issuing Bank hereby consents and agrees to the terms of the Collateral Documents
and authorizes and directs the Collateral Trustee to execute the Collateral
Documents.  Each Lender and each Issuing Bank hereby agrees, and each holder of
any Note by the acceptance thereof will be deemed to agree, that any action
taken by the Requisite Lenders or the Agent (as appropriate), in accordance with
the provisions of this Agreement or the Collateral Documents, and the exercise
by the Requisite Lenders or the Agent (as appropriate) of the powers set forth
herein or therein, together with such other powers as are reasonably incidental
thereto, shall be authorized and binding upon all of the Lenders, Issuing Banks
and the holders of any Note.

          (b)  If the Borrower fails to pay any amount of Trustee's Fees owed by
it to the Collateral Trustee pursuant to the Collateral Trust Agreement, the
Lenders agree to pay to the Collateral Trustee such unpaid Trustee's Fees,
apportioned among the Lenders ratably in accordance with each Lender's Pro Rata
Share (and no Lender shall have any obligation to pay any other Lender's Pro
Rata Share of such fees).  Any such Trustee's Fees paid by the Lenders pursuant
to this SECTION 9.07 shall be deemed to be a Revolving Loan hereunder made to
the Borrower, which Loan (together with all interest thereon) shall be payable
upon demand by the Agent and shall accrue interest for the period during which
it is outstanding at a rate equal to two percent (2.0%) per annum above the
Alternate Base Rate as in effect during such period.  The Borrower hereby
irrevocably authorizes the Lenders to make such Revolving Loans for the purpose
of paying any Trustee's Fees which the Borrower fails to pay and agrees that all
such Loans so made shall be deemed to have been requested by the Borrower.

          (c)  Prior to the satisfaction of the condition specified in Section
7.1(a) of the Collateral Trust Agreement (without limiting PARAGRAPH (d) below,
the release of the capital stock of any Material Subsidiary from the Lien
granted to the Collateral Trustee may occur only as follows:

          (I)  the Agent, on behalf of the Lenders, shall direct the Collateral
     Trustee to release the Lien on the capital stock of any Material Subsidiary
     if such Material Subsidiary is sold with the consent of the Requisite
     Lenders; and

          (ii)  in addition, the Requisite Lenders may direct the Collateral
     Trustee to release the Lien on the capital stock of any Material
     Subsidiary; PROVIDED, that all of the Lenders shall be required to direct
     the Collateral Trustee to release all or substantially all of the
     Collateral as provided in Section 7 of the Collateral Trust Agreement.

          (d)  Prior to the satisfaction of the condition specified in Section
7.1(a) of the Collateral Trust Agreement, the Agent shall direct the Collateral
Trustee to release its Lien on the capital stock of all of the domestic Material
Subsidiaries if the Borrower's senior public debt is rated Investment Grade.

          SECTION 9.08.  APPLICABLE LAW.  THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE
STATE OF NEW YORK.

          SECTION 9.09.  WAIVERS; AMENDMENT.  (a)  No failure or delay of the
Agent, any Issuing Bank or any Lender in exercising any power or right hereunder
shall operate as a waiver thereof, nor shall any single or partial exercise of
any such right or power, or any abandonment or discontinuance of steps to
enforce such a right or power, preclude any other or further exercise thereof or
the exercise of any other right or power.  The rights and remedies of the Agent,
the Issuing Banks and the Lenders hereunder and under the other Loan Documents
are cumulative and are not exclusive of any rights or remedies which they would
otherwise have.  No waiver of any provision of this Agreement or any other Loan
Document or consent to any departure by the Borrower therefrom shall in any
event be effective unless the same shall be permitted by PARAGRAPH (b) below,
and then such waiver or consent shall be effective only in the specific instance
and for the purpose for which given.  No notice or demand on the Borrower in any
case shall entitle the Borrower to any other or further notice or demand in
similar or other circumstances.

          (b)  Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to an agreement or agreements in writing
entered into by the Borrower and the Requisite Lenders; PROVIDED, HOWEVER, that
no such agreement shall (I) decrease the principal amount of, or extend the
maturity of, any scheduled principal payment date or date for the payment of any
interest on any Loan or LC Disbursement, or waive or excuse any such payment or
any part thereof, or decrease the rate of interest on any Loan or LC
Disbursement, without the prior written consent of each Lender affected thereby,
(ii) change or extend any Commitment or decrease the amount or extend the time
of payment of the Commitment Fees or LC Fees of any Lender without the prior
written consent of such Lender, or (iii) amend or modify the provisions of
SECTION 2.19, the provisions of this SECTION 9.09 or the definitions of
"Requisite Lenders" or "Pro Rata Share" without the prior written consent of
each Lender; PROVIDED FURTHER that no such agreement shall amend, modify or
otherwise affect the rights or duties of the Agent or the Issuing Banks
hereunder without the prior written consent of the Agent or the Issuing Banks,
as the case may be.


          SECTION 9.10.  INTEREST RATE LIMITATION.  Notwithstanding anything
herein to the contrary, if at any time the applicable interest rate, together
with all fees and charges which are treated as interest under applicable law
(collectively the "CHARGES"), as provided for herein or in any other document

<PAGE>

executed in connection herewith, or otherwise contracted for, charged, received,
taken or reserved by any Lender, shall exceed the maximum lawful rate (the
"MAXIMUM RATE") which may be contracted for, charged, taken, received or
reserved by such Lender in accordance with applicable law, the rate of interest
payable on such Lender's Loans, together with all Charges payable to such
Lender, shall be limited to the Maximum Rate.

          SECTION 9.11.  CONFIDENTIALITY.  Each of the Agent and the Lenders
shall hold all non-public information obtained pursuant to this Agreement (which
has been reasonably identified as such by the Borrower) in accordance with its
customary procedures for handling confidential information of this nature and in
accordance with safe and sound banking practices and will use such information
only in connection with the transactions contemplated by the Loan Documents, and
in any event may make disclosure of any such information (I) to any Agent, or
any Lender, (ii) to the extent required by law (including statute, rule,
regulation or judicial process), (iii) to counsel for any Lender or the Agent or
to their respective accountants, each of whom shall also be bound by the confi-
dentiality obligations set forth herein, (iv) to bank examiners and auditors and
appropriate government examining authorities, (v) to the extent necessary or
appropriate in connection with any litigation to which any Lender or the Agent
is a party, or (vi) subject to SECTION 9.04, to any actual or prospective
participant in or assignee of any Loan owing to or Note held by such Lender.

          SECTION 9.12.  ENTIRE AGREEMENT.  This Agreement, including the
exhibits and schedules hereto, and the other Loan Documents constitute the
entire contract between the parties relative to the subject matter hereof and
thereof.  Any previous agreement among the parties with respect to the subject
matter hereof or thereof is superseded by this Agreement and the other Loan
Documents.  Nothing in this Agreement or in the other Loan Documents, expressed
or implied, is intended to confer upon any party other than the parties hereto
and thereto any rights, remedies, obligations or liabilities under or by reason
of this Agreement or the other Loan Documents.

          SECTION 9.13.  WAIVER OF JURY TRIAL.  Each party hereto hereby waives,
to the fullest extent permitted by applicable law, any right it may have to a
trial by jury in respect of any litigation directly or indirectly arising out
of, under or in connection with this Agreement or any of the other Loan
Documents.  Each party hereto (a) certifies that no representative, agent or
attorney of any other party has represented, expressly or otherwise, that such
other party would not, in the event of litigation, seek to enforce the foregoing
waiver and (b) acknowledges that it and the other parties hereto have been
induced to enter into this Agreement and the other Loan Documents, as
applicable, by, among other things, the mutual waivers and certifications in
this SECTION 9.13.

          SECTION 9.14.  SEVERABILITY.  In the event any one or more of the
provisions contained in this Agreement or in any other Loan Document should be
held invalid, illegal or unenforceable in any respect, the validity, legality
and enforceability of the remaining provisions contained herein and therein
shall not in any way be affected or impaired thereby.  The parties shall
endeavor in good-faith negotiations to replace the invalid, illegal or
unenforceable provisions with valid provisions the economic effect of which
comes as close as possible to that of the invalid, illegal or unenforceable
provisions.

          SECTION 9.15.  COUNTERPARTS.  This Agreement may be executed in two or
more counterparts, each of which shall constitute an original but all of which
when taken together shall constitute but one contract, and shall become effec-
tive as provided in SECTION 9.03.

          SECTION 9.16.  HEADINGS.  Article and Section headings and the Table
of Contents used herein are for convenience of reference only, are not part of
this Agreement and are not to affect the construction of, or to be taken into
consideration in interpreting, this Agreement.

<PAGE>

          SECTION 9.17.  JURISDICTION; CONSENT TO SERVICE OF PROCESS.  (a)  THE
BORROWER HEREBY IRREVOCABLY AND UNCONDITIONALLY SUBMITS, FOR ITSELF AND ITS
PROPERTY, TO THE NONEXCLUSIVE JURISDICTION OF ANY NEW YORK STATE COURT OR
FEDERAL COURT OF THE UNITED STATES OF AMERICA SITTING IN NEW YORK CITY, AND ANY
APPELLATE COURT FROM ANY THEREOF, IN ANY ACTION OR PROCEEDING ARISING OUT OF OR
RELATING TO THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS, OR FOR RECOGNITION OR
ENFORCEMENT OF ANY JUDGMENT, AND EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY
AND UNCONDITIONALLY AGREES THAT ALL CLAIMS IN RESPECT OF ANY SUCH ACTION OR
PROCEEDING MAY BE HEARD AND DETERMINED IN SUCH NEW YORK STATE OR, TO THE EXTENT
PERMITTED BY LAW, IN SUCH FEDERAL COURT.  THE BORROWER IRREVOCABLY CONSENTS TO
THE SERVICE OF PROCESS OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR
PRECEDING BY THE MAILING OF COPIES THEREOF BY REGISTERED OR CERTIFIED MAIL,
POSTAGE PREPAID, TO ITS NOTICE ADDRESS SPECIFIED IN SECTION 9.01, SUCH NOTICE TO
BECOME EFFECTIVE TEN (10) DAYS AFTER ITS MAILING. EACH OF THE PARTIES HERETO
AGREES THAT A FINAL JUDGMENT IN ANY SUCH ACTION OR PROCEEDING SHALL BE
CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT ON THE JUDGMENT OR
IN ANY OTHER MANNER PROVIDED BY LAW.  NOTHING IN THIS AGREEMENT SHALL AFFECT ANY
RIGHT THAT ANY PARTY MAY OTHERWISE HAVE TO BRING ANY ACTION OR PROCEEDING
RELATING TO THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS IN THE COURTS OF ANY
JURISDICTION.

          (b)  THE BORROWER HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO
THE FULLEST EXTENT IT MAY LEGALLY AND EFFECTIVELY DO SO, ANY OBJECTION WHICH IT
MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY SUIT, ACTION OR
PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE OTHER LOAN
DOCUMENTS IN ANY NEW YORK STATE OR FEDERAL COURT.  EACH OF THE PARTIES HERETO
HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, THE DEFENSE
OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF SUCH ACTION OR PROCEEDING IN ANY
SUCH COURT.

          SECTION 9.18.  DEFAULTING LENDER.  If any Lender fails to fund its Pro
Rata Share of any Revolving Loan Borrowing requested or deemed requested by the
Borrower (the funded portion of such Borrowing being hereinafter referred to as
a "NON PRO RATA LOAN"), then until the earlier of such Lender's cure of such
failure or the termination of the Commitments, upon the Borrower's request, the
proceeds of all amounts thereafter repaid to the Agent by the Borrower and
otherwise required to be applied to such Lender's share of all other Obligations
pursuant to the terms of this Agreement shall be advanced to the Borrower by the
Agent on behalf of such Lender to cure, in full or in part, such failure by such
Lender, but shall nevertheless be deemed to have been paid to such Lender in
satisfaction of such other Obligations.  Notwithstanding anything in this
Agreement to the contrary:

          (I)  the foregoing provisions of this SECTION 9.18 shall apply only
     with respect to the proceeds of payments of Obligations and shall not
     affect the conversion or continuation of Loans pursuant to SECTION 2.12;

          (ii) any such Lender shall be deemed to have cured its failure to fund
     its Pro Rata Share of any Revolving Loan Borrowing at such time as an
     amount equal to such Lender's original Pro Rata Share of the requested
     principal portion of such Borrowing is fully funded to the Borrower,
     whether made by such Lender itself or by operation of the terms of this
     SECTION 9.18, and whether or not the Non Pro Rata Loan with respect thereto
     has been converted or continued;

          (iii) amounts advanced to the Borrower under this SECTION 9.18 to
     cure, in full or in part, any such Lender's failure to fund its Pro Rata
     Share of any Revolving Loan Borrowing ("CURE LOANs") shall bear interest at
     the rate applicable to ABR Loans under SECTION 2.08 in effect from time to
     time, and for all other purposes of this Agreement shall be treated as if
     they were ABR Loans;

          (iv)  regardless of whether or not an Event of Default has occurred or
     is continuing, and notwithstanding the instructions of the Borrower as to
     its desired application, all repayments of principal

<PAGE>

     which would be applied to the outstanding ABR Loans shall be applied FIRST,
     ratably to all ABR Loans constituting Non Pro Rata Loans, SECOND, ratably
     to ABR Loans other than those constituting Non Pro Rata Loans or Cure Loans
     and, THIRD, ratably to ABR Loans constituting Cure Loans;

          (v)  unless and until the earlier of any such Lender's cure of the
     failure to fund its Pro Rata Share of any Revolving Loan Borrowing and the
     termination of the Commitments, the term "Requisite Lenders" for all
     purposes of this Agreement shall exclude all Lenders whose failure to fund
     their respective Pro Rata Shares of such Revolving Loan Borrowing have not
     been so cured; and

          (vi) unless and until any such Lender's failure to fund its Pro Rata
     Share of any Revolving Loan Borrowing is cured in accordance with this
     SECTION 9.18, such Lender shall not be entitled to any Commitment Fees with
     respect to its Revolving Credit Commitment, and such Lender shall be
     required to refund to the Borrower any portion of the Commitment Fees
     attributable to the period beginning on the day of such Lender's failure to
     fund and ending on the day the Commitments are terminated or such default
     has been cured.

<PAGE>

          IN WITNESS WHEREOF, the Borrower, the Agent, and the Lenders have
caused this Agreement to be duly executed by their respective authorized
officers as of the day and year first above written.

          (iv)  There are no actions or proceedings pending, or, to the

Requisite Lenders, including, without limitation, the release in accordance with
SECTION 7.4 of any portion of the Collateral from the Liens created under the
Security Documents, and shall release all of the Collateral when required by
SECTION 7.3 hereof from the Liens created under the Security Documents,
PROVIDED, HOWEVER, that the Trustee shall not be obligated to take any such
action which is in conflict with any provisions of law or of this Agreement or
the Security Documents or with respect to which the Trustee has not received
adequate security or indemnity as provided in SECTION 6.4(d). The Trustee, prior
to its receipt of a Notice of Actionable Default, shall with reasonable
promptness give notice to the Company of any such request from the Lenders or
from the Agent on behalf of the Lenders, but it is hereby expressly agreed that
the Trustee's failure to give such notice to the Company shall not affect the
validity of the Lenders' or the Agent's request to the Trustee.

          Section 2.4.  ADDITIONAL SECURITY DOCUMENTS.  The Company shall
immediately notify the Trustee in the event that any Grantor or any other
Subsidiary of the Company becomes obligated to grant a Lien in any property to
the Trustee under the terms of the Credit Agreement or the Pledge Agreements but
which is not covered by a Security Document in a manner which will perfect the
Lien on such property in favor of the Trustee without further act or deed of the
Trustee, such Grantors or such Subsidiary and, to the extent that such security
interest may be perfected by the execution and/or filing of Security Documents,
such Grantor or other Subsidiary of the Company shall immediately prepare,
execute and deliver to the Trustee such Security Documents (including, without
limitation, a Pledge Agreement), in form and substance satisfactory to the
Requisite Lenders, as are necessary to perfect the Lien on such property in
favor of the Trustee.  If the signature of the Trustee is required on any such
Security Document, the applicable Grantor shall present such Security Document
to the Trustee for signature and the Trustee shall execute such Security
Document and such Grantor shall file such Security Document with appropriate
public filing and/or recording offices if such filing and/or recording is
required or advisable to perfect or protect the Lien upon and security interest
in such property in favor of the Trustee.  Such Grantor shall supply the Trustee
with an executed copy of each such Security Document and satisfactory proof that
each such Security Document has been properly filed or recorded, if filing or
recording is required under this SECTION 2.4.

          2.5.  POWERS OF ATTORNEY.  The Grantors hereby irrevocably constitute
and appoint the Trustee and any officer or agent thereof, with full power of
substitution, as its true and lawful attorney-in-fact with full power

attorney-in-fact, from time to time in the Trustee's discretion, for the purpose
of signing documents and taking other action to perfect, preserve and protect

of attorney is a power coupled with an interest, shall be irrevocable and shall
not be subject to the limitations of SECTION 3.2(a) of this Agreement.

remedies with respect to the Collateral, and (B) the Requisite Lenders shall

direction of the Requisite Lenders shall, exercise the rights and remedies

or this Agreement; PROVIDED, HOWEVER, under no circumstances shall the Trustee
be liable for following the written instructions of the Requisite Lenders.

          (c)  Nothing in this SECTION 3.6 shall impair the right of the Trustee
in its discretion to take or omit to take any action which action or omission is
deemed proper by the Trustee and which is not inconsistent with any direction of
the Requisite Lenders; PROVIDED, HOWEVER, the Trustee shall not be under any
obligation, as a result of this SECTION 3.6, to take any action which is

or by statute.

          (b)  No delay or omission by the Trustee in the exercise of any right,
remedy or power accruing upon any Actionable Default shall impair any such

shall vest in the Corporate Trustee, and funds on deposit in the Collateral
Account and other Trust Agreement Collateral shall constitute part

                                      -12-

SECTION 4.5 hereof, all moneys held by the Corporate Trustee in the Collateral
Account shall, to the extent available for distribution, be distributed (or

and each succeeding Distribution Date as follows:

          FIRST:  To the Trustee in an amount equal to the Trustee's Fees
     which are unpaid as of such Distribution Date, and to any Secured
     Party which has theretofore advanced or paid any such Trustee's Fees
     in an amount equal to the amount thereof so advanced or paid by such
     Secured Party prior to such Distribution Date; PROVIDED, HOWEVER, that
     nothing herein is intended to relieve any of the Grantors of their
     respective obligations to pay such costs, fees, expenses and
     liabilities from funds outside of the Collateral Account;

          SECOND:  To the Secured Parties in an amount equal to the unpaid
     Secured Debt which is then due and payable and to secure unpaid
     Secured Debt which is not yet due and payable as provided in SECTION
     4.4(b) below; PROVIDED, if such moneys shall be insufficient to pay
     and/or secure in full such amounts, then to the payment and/or

     or their respective successors or assigns, or to whomever may be
     lawfully entitled to receive the same, or as a court of competent
     jurisdiction may direct, PROVIDED, HOWEVER, that if any Secured Party
     shall have notified the Trustee in writing that a claim is pending for
     which such Secured Party is entitled to the benefits of an
     indemnification, reimbursement or similar provision under which
     amounts are not yet due but with respect to which any of the Grantors
     continue to be contingently liable, and amounts payable by such
     Grantor with respect thereto are secured by the Trust Estate, the
     Trustee shall continue to hold the amount specified in such notice in
     the Collateral Account until such Grantor's liability with respect
     thereto is discharged or released to the satisfaction of such Secured
     Party.

          (b)  In the event any of the Obligations, Public Debt or Refinancing
Debt consisting of principal is not due and payable on any Distribution Date,
the Grantors shall be deemed for purposes of the distribution made on such
Distribution Date to have an obligation to provide cash collateral in the amount
of such principal, and the amount distributed with respect to such obligation to
provide cash collateral shall be held by the Agent (if with respect to the
Obligations) or the applicable Public Trustee or Representative (if with respect
to the Public Debt or Refinancing Debt), subject to the provisions of this
SECTION 4.4(b), as cash collateral for such Secured Debt. In the event any
Obligations with respect to Letters of Credit (other than fees or unincurred
costs and expenses) are not due and payable on any Distribution Date, the
Grantors shall be deemed for purposes of the distribution made on such
Distribution Date to have an obligation to provide cash collateral in an amount
equal to the maximum amount of such Obligations, and the amount distributable
with respect to such obligation to provide cash collateral shall be held by the
Agent, subject to the provisions of this SECTION 4.4(b), as cash collateral for
such Obligations.  Amounts held by the Agent, any Public Trustee, any
Representative or the Trustee as cash collateral under this SECTION 4.4(b) shall
be invested in investments of the kinds referred to in SECTION 4.3(i) or 4.3(ii)
of this Agreement having

                                      -14-
<PAGE>

maturities of ninety (90) days or less, and interest earned on such investments
shall be (i) first, applied to interest accruing on the Secured Debt with
respect to which such cash collateral is held and (ii) second, deposited in the
Collateral Account.  The amount of any Secured Debt secured by such cash
collateral shall be reduced by the amount of such cash collateral for purposes
of calculating the amount of subsequent distributions under SECTION 4.4(a).
When any Secured Debt secured by cash collateral as provided above becomes due
and payable, the amount due and payable shall be paid out of such cash collat-
eral, up to but not in excess of the percentage of the principal amount of other
Secured Debt theretofore paid out of distributions from the Collateral Account.
The balance of such cash collateral, if any, shall be deposited in the
Collateral Account.

          Section 4.5.  APPLICATION OF MONEYS DISTRIBUTABLE TO HOLDERS OF PUBLIC
DEBT AND REFINANCING DEBT.  If at any time any moneys collected or received by
the Trustee pursuant to this Agreement or any of the Security Documents are
distributable pursuant to SECTIONS 4.4(a) or 4.4(b) of this Agreement to any
Public Trustee or Representative, and if such Public Trustee or Representative
shall notify the Trustee that no provision is made under the applicable Public
Indenture or Refinancing Instrument (i) for the application by such Public
Trustee or Representative of such amounts so distributable (whether by virtue of
the Public Debt or Refinancing Debt not having become due and payable or
otherwise), or (ii) for the receipt and the holding by such Public Trustee or
Representative of such amounts pending the application thereof, then the Trustee
shall invest such amounts in investments of the kinds referred to in SECTIONS
4.3(i) or 4.3(ii) of this Agreement having maturities of ninety (90) days or
less, and shall hold all such amounts so distributable, and all such investments
and the proceeds thereof, in lieu of such Public Trustee or Representative if
such amounts are distributable as cash collateral pursuant to SECTION 4.4(b), or
otherwise in trust solely for such Public Trustee or Representative (in its
capacity as trustee) and for no other purpose, until such time as such Public
Trustee or Representative shall request the delivery thereof by the Trustee to
such Public Trustee or Representative for application by it pursuant to the
Public Debt or Refinancing Debt (to the extent such application is permitted
hereunder).


                                    SECTION 5

Company, the names of the Holders of the Obligations, the unpaid principal
amount thereof owing to each Lender and whether any amount of Obligations
outstanding is subordinated to any extent to any of the other Secured Debt,

under each Public Indenture is subordinated to any extent to any of the other
Secured Debt, and (iv) with respect to the Refinancing Debt, the name of the

agrees to furnish promptly to the Trustee any changes or additions to such list.

          Section 5.3.  COMPENSATION AND EXPENSES.  The Grantors jointly and
severally agree to pay to the Trustee the Trustee's customary fees as
compensation for the Trustee's services hereunder and under the Security
Documents and for administering the Trust Estate, and from time to time
following notice thereof and 10 Business Days, all of the fees, costs and
expenses of the Trustee (including, without limitation, the reasonable fees and
disbursements of its counsel and such special counsel, accountants or other
experts as the Trustee elects to retain) (i) arising in connection with the
preparation, execution, delivery, modification (requested by the Company),
restatement, amendment (requested by the Company) or termination of this
Agreement and each Security Document or the enforcement (whether in the context
of a civil action, adversary proceeding, workout or otherwise) of any of the
provisions hereof or thereof, or (ii) incurred or required to be advanced in
connection with the administration of the Trust Estate, the sale or other
disposition or the custody, preservation or protection of Collateral pursuant to
any Security Document and the exercise or enforcement of the Trustee's rights
under this Agreement and in and to the Collateral and the Trust Estate.  As
security for such payment, the Trustee shall have a Lien prior to the Secured
Debt upon all Collateral and other property and funds held or collected by the
Trustee as part of the Trust Estate.

          Section 5.4.  STAMP AND OTHER SIMILAR TAXES.  The Grantors jointly and
severally agree to indemnify and hold harmless the Trustee and each Holder from,
and shall reimburse the Trustee and each Holder for, any present or future claim
for liability for any stamp or other similar tax and any penalties or interest
with respect thereto, which may be assessed, levied or collected by any
jurisdiction in connection with this Agreement, any Security Document, the Trust
Estate, or the attachment or perfection of the security interest granted to the
Trustee in any Collateral.  The obligations of the Grantors under this SECTION
5.4 shall survive the termination of the other provisions of this Agreement.

          Section 5.5.  FILING FEES, EXCISE TAXES, ETC.  The Grantors jointly
and severally agree to pay or to reimburse the Trustee for any and all amounts

Agreement and each Security Document and agree to save the Trustee harmless from
and against any and all liabilities with respect to or resulting from any delay
in paying or omission to pay such taxes and fees.  The obligations of the
Grantors under this SECTION 5.5 shall survive the termination of the other
provisions of this Agreement.

          Section 5.6.  INDEMNIFICATION.  (a)  The Grantors jointly and
severally agree to pay, indemnify and hold the Trustee and each of its agents
harmless from and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind or nature whatsoever with respect to the execution, delivery, enforcement,
performance and administration of this Agreement and the Security Documents,
unless arising from the gross negligence, bad faith or willful misconduct of
such of the Trustee or the agents that are seeking indemnification.  As security
for such payment, the Trustee shall have a Lien prior to the Secured Debt upon
all Collateral and other property and funds held or collected by the Trustee as
part of the Trust Estate.

          (b)  In any suit, proceeding or action brought by the Trustee

                                      -16-
<PAGE>

under or with respect to the Collateral for any sum owing thereunder, or to
enforce any provisions thereof, or of any of the Security Documents or this
Agreement, the Grantors jointly and severally agree to save, indemnify and keep
the Trustee and the Holders harmless from and against all expense, loss or
damage suffered by reason of any defense, setoff, counterclaim, recoupment or
reduction of liability whatsoever of the obligor thereunder, arising out of a
breach by the Company or any of the Grantors of any of their respective
obligations hereunder or thereunder or arising out of any other agreement,
indebtedness or liability at any time owing to, or in favor of, such obligor or
its successors from the Company or Grantors, and all such obligations of the
Company or the Grantors shall be and remain enforceable against and only against
the Company and the Grantors and shall not be enforceable against the Trustee or
any Holder.

          (c)  The agreements in this SECTION 5.6 shall survive the termination
of the other provisions of this Agreement.

          Section 5.7.  FURTHER ASSURANCES.  At any time and from time to time,
upon the written request of the Trustee, and at the expense of the applicable
Grantor, each Grantor will promptly execute and deliver any and all such further
instruments and documents and take such further action as the Trustee may
reasonably deem necessary or desirable in obtaining the full benefits of this
Agreement and the Security Documents and of the rights and powers herein and
therein granted, including, without limitation, the filing of any financing or
continuation statements or other instruments to perfect the Liens and security
interests granted thereby.  The Grantors shall, not later than thirty (30) days
after the Requisite Lenders' or the Trustee's request therefor, deliver to the
Trustee an opinion of independent counsel, addressed to the Trustee for the
benefit of the Holders, concerning the continued perfection and priority of the
Liens and security interests created by the Security Documents (excluding,
however, those Liens and security interests which, in accordance with the terms
of this Agreement and the Security Documents, have been released); PROVIDED,
HOWEVER, that the Trustee shall have no obligation to request such opinion from
any of the Grantors.  The Grantors shall, in all of their published financial
statements customarily prepared with footnotes or filed with the Securities and
Exchange Commission, indicate by footnote or otherwise that the Secured Debt is
secured pursuant to this Agreement and the Security Documents.


                                    SECTION 6
                                   THE TRUSTEE

          Section 6.1.  ACCEPTANCE OF TRUST.  The Trustee, for itself and its
successors, hereby accepts the trusts created by this Agreement upon the terms
and conditions hereof, including those contained in this SECTION 6.

          Section 6.2.  EXCULPATORY PROVISIONS.  (a)  The Trustee shall not be
responsible in any manner whatsoever for the correctness of any recitals,
statements, representations or warranties contained herein or in the Security
Documents, except for those made by the Trustee.  The Trustee makes no
representations as to the value or condition of the Trust Estate or any part
thereof, or as to the title of the Grantors thereto or as to the security
afforded by the Security Documents or this Agreement or, except as set forth in
SECTION 2.2 of this Agreement, as to the validity, execution, enforceability,
legality or sufficiency of this Agreement, any Security Document or of the
Secured Debt secured hereby and thereby, and the Trustee shall incur no
liability or responsibility in respect of any such matters.  The Trustee shall
not be responsible for insuring the Trust Estate or for the payment of taxes,
charges, assessments or Liens upon the Trust Estate or otherwise as to the
maintenance of the Trust Estate, except that (i) in the event the Trustee enters
into possession of a part or all of the Trust Estate, the Trustee shall preserve
the part in its possession, and (ii) the Trustee

                                      -17-
<PAGE>

will promptly, and at its own expense, take such action as may be necessary duly
to remove and discharge (by bonding or otherwise) any Trustee's Lien on any part
of the Trust Estate or any other Lien on any part of the Trust Estate resulting
from claims against it (whether individually or as Trustee) not related to the
administration of the Trust Estate or (if so related) resulting from gross
negligence, bad faith or willful misconduct on its part.

          (b)  The Trustee shall not be required to ascertain or inquire as to
the performance by any of the Grantors of any of the covenants or agreements
contained herein, in any Security Document or in any Debt Instrument.  Whenever
it is necessary, or in the opinion of the Trustee advisable, for the Trustee to
ascertain the amount of Secured Debt then held by a Holder, the Trustee may rely
on a certificate of such Holder as to such amount.

          (c)  Wilmington Trust Company shall, in its individual capacity and at
its own cost and expense, promptly take all action as may be necessary to
discharge any Trustee's Liens or any other Lien resulting from claims against it
or William J. Wade (whether individually or as Trustee) not related to the
administration of the Trust Estate or (if so related) resulting from gross
negligence, bad faith or willful misconduct on its or his part.

          (d)  Subject to the provisions of the Pledge Agreements concerning the
Trustee's duty of care with respect to certificates evidencing the Pledged Stock
in the Trustee's possession, the Trustee shall not be personally liable for any
acts, omissions, errors of judgment or mistakes of fact or law made, taken or
omitted to be made or taken by it in accordance with this Agreement or any
Security Document (including, without limitation, acts, omissions, errors or
mistakes with respect to the Collateral), except for those arising out of or in
connection with the Trustee's gross negligence, bad faith or willful misconduct.
Notwithstanding anything set forth herein to the contrary, the Trustee shall
have a duty of reasonable care with respect to any "instruments" (as defined in
the UCC) which are delivered to the Trustee or its designated representatives as
part of the Collateral and are in the Trustee's or its designated
representatives' possession and control.

          Section 6.3.  DELEGATION OF DUTIES.  The Trustee may execute any of
the trusts or powers hereof and perform any duty hereunder either directly or by
or through agents, nominees or attorneys-in-fact, which (except with respect to
the Trustee's duties to maintain possession of any Collateral or any other
portion of the Trust Estate as expressly set forth herein or in the Security
Documents) may include employees or officers of the Company, PROVIDED, that the
Trustee shall obtain a written acknowledgment from such agents, nominees or
attorneys-in-fact that they shall be liable to the Holders for losses or damages
incurred by any such Holder as a result of such agent's, nominee's or
attorneys'-in-fact gross negligence, bad faith or willful misconduct as and to
the extent the Trustee would be liable for such losses or damages if the actions
or omissions of such agents, nominees or attorneys-in-fact constituting such
gross negligence, bad faith or willful misconduct had been actions or omissions
of the Trustee.  The Trustee shall be entitled to advice of counsel concerning
all matters pertaining to such trusts, powers and duties.  The Trustee shall not
be responsible for the negligence or misconduct of any agents, nominees or
attorneys-in-fact selected by it without gross negligence, bad faith or willful
misconduct.

          Section 6.4.  RELIANCE BY TRUSTEE.  (a)  Whenever in the
administration of the trusts of this Agreement the Trustee shall deem it
necessary or desirable that a matter be proved or established with respect to
any of the Grantors in connection with the taking, suffering or omitting of any
action hereunder by the Trustee, such matter (unless other evidence in respect
thereof is herein specifically prescribed) may be deemed to be conclusively
provided or established by a certificate of an Authorized Officer of the Company
delivered to the Trustee, and such certificate shall be full

                                      -18-
<PAGE>

warranty to the Trustee for any action taken, suffered or omitted in reliance
thereon, subject, however, to the provisions of SECTION 6.5 of this Agreement.

          (b)  The Trustee may consult with Richards, Layton & Finger or other
counsel reasonably satisfactory to the Requisite Lenders, accountants or other
experts in connection with the fulfillment of its duties hereunder, and the
Trustee shall be entitled to rely on the opinion of such counsel, accountants or
other experts in connection with any action taken, omitted to be taken or
suffered by the Trustee in fulfilling its duties hereunder.  The Trustee shall
have the right at any time to seek instructions concerning the administration of
the Trust Estate from any court of competent jurisdiction.

          (c)  The Trustee may rely, and shall be fully protected in relying,
upon any resolution, statement, certificate, instrument, opinion, report,
notice, request, consent, order, bond or other paper or document which it has no
reason to believe to be other than genuine and to have been signed or presented
by the proper party or parties or, in the case of cables, telecopies and
telexes, to have been sent by the proper party or parties, PROVIDED, HOWEVER,
that for the purpose of identifying the Requisite Lenders and the amounts of
their Revolving Credit Commitments and of Secured Debt held by them, the
information provided by the Company to the Trustee pursuant to SECTION 5.2 of
this Agreement must be confirmed in writing by the Agent.  In the absence of its
gross negligence, bad faith or willful misconduct, the Trustee may conclusively
rely, except as provided above, as to the truth of the statements and the
correctness of the opinions expressed therein, upon any certificates or opinions
furnished to the Trustee and conforming to the requirements of this Agreement or
any Security Document.

          (d)  If the Trustee has been requested to take action pursuant to
SECTION 2.3 or SECTION 3.6 of this Agreement, the Trustee shall not be under any
obligation to exercise any of the rights or powers vested in the Trustee by this
Agreement or any Security Document unless the Trustee shall have been provided
adequate security and indemnity against the costs, expenses and liabilities
which may be incurred by it in compliance with such request or direction,
including such reasonable advances as may be requested by the Trustee.

           Section 6.5.  LIMITATIONS ON DUTIES OF TRUSTEE.  (a)  The Trustee
shall be obliged to perform such duties and only such duties as are specifically
set forth in this Agreement or in any Security Document, and no implied
covenants or obligations shall be read into this Agreement or any Security
Document against the Trustee.  The Trustee shall, upon receipt of a Notice of
Actionable Default and during such time as such Notice of Actionable Default
shall not have been withdrawn in accordance with the provisions of SECTION
3.1(b) hereof, exercise the rights and powers vested in it by this Agreement or
by any Security Document, and the Trustee shall not be liable with respect to
any action taken or omitted by it in accordance with the direction of the
Requisite Lenders pursuant to SECTION 3.6 of this Agreement.

          (b)  Except as herein otherwise expressly provided, including, without
limitation, upon the written request of the Requisite Lenders pursuant to
SECTION 3.6 of this Agreement, the Trustee shall not be under any obligation to
take any action which is discretionary with the Trustee under the provisions
hereof or under any Security Document.  The Trustee shall furnish to each Holder
promptly upon receipt thereof a copy of each certificate or other paper
furnished to the Trustee by any of the Grantors under or in respect of this
Agreement, any Security Document or any of the Trust Estate, unless by the
express terms of any Security Document a copy of the same is required to be
furnished by some other Person directly to the Holders, or the Trustee shall
have determined that the same has already been so furnished.

          Section 6.6.  MONEYS TO BE HELD IN TRUST.  All moneys received by

                                      -19-
<PAGE>

the Trustee under or pursuant to any provision of this Agreement or any Security
Document shall be held in trust for the purposes for which they were paid or are
held.

          Section 6.7.  RESIGNATION AND REMOVAL OF THE TRUSTEE.  (a)  The
Corporate Trustee or Individual Trustee may at any time, by giving sixty (60)
days' prior written notice to the Company and the Holders, resign and be dis-
charged of the responsibilities hereby created, such resignation to become
effective upon the appointment of a successor Trustee by the Requisite Lenders
with the consent of the Company, such consent not to be unreasonably withheld,
and the acceptance of such appointment by such successor Trustee.  The Corporate
Trustee or Individual Trustee may be removed at any time and a successor Trustee
appointed by the affirmative vote of the Requisite Lenders; PROVIDED THAT the
Corporate Trustee or Individual Trustee shall be entitled to its or his fees and
expenses to the date of removal.  If no successor Trustee shall be appointed and
approved within sixty (60) days from the date of the giving of the aforesaid
notice of resignation or within sixty (60) days from the date of such removal,
the Corporate Trustee or Individual Trustee, as applicable, shall, or any Holder
may, apply to any court of competent jurisdiction to appoint a successor trustee
or trustees to act until such time, if any, as a successor trustee or trustees
shall have been appointed as above provided.  Any successor trustee or trustees
so appointed by such court shall immediately and without further act be
superseded by any successor trustee or trustees approved by the Requisite
Lenders with the consent of the Company, such consent not to be unreasonably
withheld, as above provided.

          (b)  If at any time the Corporate Trustee or Individual Trustee shall
resign, be removed or otherwise become incapable of acting, or if at any time a
vacancy shall occur in the office of the Corporate Trustee or Individual Trustee
for any other cause, a successor trustee or trustees may be appointed by the
Requisite Lenders, with the consent of the Company, such consent not to be
unreasonably withheld, and the powers, duties, authority and title of the
predecessor trustee or trustees terminated and canceled without procuring the
resignation of such predecessor trustee or trustees, and without any other
formality (except as may be required by applicable law) than the appointment and
designation of a successor trustee or trustees in writing, duly acknowledged,
delivered to the predecessor trustee or trustees and the Company, and filed for
record in each public office, if any, in which this Agreement is required to be
filed.

          (c)  The appointment and designation referred to in SECTION 6.7(b) of
this Agreement shall, after any required filing, be full evidence of the right
and authority to make the same and all of the facts therein recited, and this
Agreement shall vest in such successor trustee or trustees, without any further
act, deed or conveyance, all of the estate and title of its predecessor or their
predecessors, and upon any required filing for record the successor trustee or
trustees shall become fully vested with all the estates, properties, rights,
powers, trusts, duties, authority and title of its predecessor or their
predecessors; but such predecessor or predecessors shall, nevertheless, on the
written request of the Requisite Lenders, the Company, or any successor trustee
or trustees, execute and deliver an instrument transferring to such successor or
successors all the estates, properties, rights, powers, trusts, duties,
authority and title of such predecessor or predecessors hereunder and shall
deliver all securities and moneys held by it or them to such successor trustee
or trustees.  Should any deed, conveyance or other instrument in writing from
any of the Grantors be required by any successor trustee or trustees for more
fully and certainly vesting in such successor trustee or trustees the estates,
properties, rights, powers, trusts, duties, authority and title vested or
intended to be vested in the predecessor trustee or trustees, any and all such
deeds, conveyances and other instruments in writing shall, on request of such
successor trustee or trustees, be so executed, acknowledged and delivered.

                                      -20-
<PAGE>

          (d)  Any required filing for record of the instrument appointing a
successor trustee or trustees as hereinabove provided shall be at the expense of
the Company.  The resignation of any trustee or trustees and the instrument or
instruments removing any trustee or trustees, together with all other
instruments, deeds and conveyances provided for in this SECTION 6 shall, if
required by law, be forthwith recorded, registered and filed by and at the
expense of the Company, wherever this Agreement is recorded, registered and
filed.

          Section 6.8.  STATUS OF SUCCESSORS TO THE CORPORATE TRUSTEE.  Every
successor to Wilmington Trust Company appointed pursuant to SECTION 6.7 of this
Agreement and every corporation resulting from a merger or consolidation
pursuant to SECTION 6.9 of this Agreement shall be a bank or trust company in
good standing and having power so to act, incorporated under the laws of the
United States or any State thereof or the District of Columbia, and having its
principal corporate trust office within the forty-eight (48) contiguous States,
and shall also have capital, surplus and undivided profits of not less than
$100,000,000.

          Section 6.9.  MERGER OF THE CORPORATE TRUSTEE.  Any corporation into
which the Corporate Trustee shall be merged, or with which it shall be
consolidated, or any corporation resulting from any merger or consolidation to
which the Corporate Trustee shall be a party, shall be the Corporate Trustee
under this Agreement without the execution or filing of any paper or any further
act on the part of the parties hereto.

          Section 6.10.  ADDITIONAL CO-TRUSTEES; SEPARATE TRUSTEES.  (a)  If at
any time or times it shall be necessary or prudent in order to conform to any
law of any jurisdiction in which any of the Collateral shall be located, or the
Trustee shall be advised by counsel, satisfactory to it, that it is necessary or
prudent in the interest of the Holders, or the Requisite Lenders shall in
writing so request, or the Trustee shall deem it desirable for its own
protection in the performance of its duties hereunder, the Trustee and the
Grantors shall execute and deliver all instruments and agreements necessary or
proper to constitute another bank or trust company, or one or more persons
approved by the Trustee and the Grantors either to act as co-trustee or
co-trustees of all or any of the Collateral, jointly with the Trustee originally
named herein or any successor or successors, or to act as separate trustee or
trustees of any such property.  In the event the Grantors shall not have joined
in the execution of such instruments and agreements within ten (10) days after
the receipt of a written request from the Trustee so to do, or in case an
Actionable Default shall have occurred and be continuing, the Trustee may act
under the foregoing provisions of this SECTION 6.10 without the concurrence of
the Grantors, and the Grantors hereby irrevocably appoint the Trustee as their
agent and attorney to act for them under the foregoing provisions of this
SECTION 6.10 in either of such contingencies.

          (b)  Every separate trustee and every co-trustee, other than any
trustee which may be appointed as successor to Wilmington Trust Company or
William J. Wade, shall, to the extent permitted by law, be appointed and act and
be such, subject to the following provisions and conditions, namely:

          (i)  all rights, powers, duties and obligations conferred upon
     the Trustee in respect of the custody, control and management of
     moneys, papers or securities shall be exercised solely by Wilmington
     Trust Company, or its successors as Trustee hereunder;

          (ii)  all rights, powers, duties and obligations conferred or
     imposed upon the Trustee hereunder shall be conferred or imposed and
     exercised or performed by the Trustee and such separate trustee or
     separate trustees or co-trustee or co-trustees, jointly, as shall be
     provided in the instrument appointing such separate trustee or
     separate trustees or

                                      -21-
<PAGE>

     co-trustee or co-trustees, except to the extent that under any law of any
     jurisdiction in which any particular act or acts are to be performed, the
     Trustee shall be incompetent or unqualified to perform such act or acts, in
     which event such rights, powers, duties and obligations shall be exercised
     and performed by such separate trustee or separate trustees or co-trustee
     or co-trustees;

          (iii)  no power given hereby to, or which it is provided hereby
     may be exercised by, any such co-trustee or co-trustees or separate
     trustee or separate trustees, shall be exercised hereunder by such
     co-trustee or co-trustees or separate trustee or separate trustees,
     except jointly with, or with the consent in writing of, the Trustee,
     anything herein contained to the contrary notwithstanding;

          (iv)  no trustee hereunder shall be personally liable by reason
     of any act or omission of any other trustee hereunder; and

          (v)  the Grantors and Trustee, at any time by an instrument in
     writing, executed by them jointly, may accept the resignation of or
     remove any such separate trustee or co-trustee, and in that case, by
     an instrument in writing executed by the Grantors and the Trustee
     jointly, may appoint a successor to such separate trustee or
     co-trustee, as the case may be, anything herein contained to the
     contrary notwithstanding.  In the event that the Grantors shall not
     have joined in the execution of any instrument within ten (10) days
     after the receipt of a written request from the Trustee so to do, or
     in case an Actionable Default shall have occurred and be continuing,
     the Trustee shall have the power to accept the resignation of or
     remove any such separate trustee or co-trustee and to appoint a
     successor without the concurrence of the Grantors, the Grantors hereby
     irrevocably appointing the Trustee their agent and attorney to act for
     them in such connection in either of such contingencies.  In the event
     that the Trustee shall have appointed a separate trustee or separate
     trustees or co-trustee or co-trustees as above provided, it may at any
     time, by an instrument in writing, accept the resignation of or remove
     any such separate trustee or co-trustee, the successor to any such
     separate trustee or co-trustee to be appointed by the Grantors and the
     Trustee, or by the Trustee alone, as hereinabove provided in this

     paid in full.

          Section 7.2.  PROCEDURE FOR RELEASE.  Upon the occurrence of the
events specified in either SECTION 7.1(a), 7.1(b) or 7.1(c), the Company, on
behalf of the Grantors, shall deliver a Discharge Notice to the Trustee (with a
copy thereof given to the Agent, each Public Trustee and each Representative).
Upon receipt by the Trustee of a Discharge Notice certifying that events set
forth in SECTION 7.1(a), 7.1(b) or 7.1(c) above have occurred, the Trustee shall
request the Agent to confirm in writing that the event described in SECTION
7.1(a)(i), 7.1(b)(i) or 7.1(c)(i) of this Agreement has occurred.

          Section 7.3.  EFFECTIVE TIME OF RELEASE.  (a)  The Trustee shall
release the Collateral upon receipt by the
Trustee of (i) a Discharge Notice and (ii) the written confirmation from the

and interest of the Trustee in, to and under the Trust Estate, the Collateral
and the Security Documents shall terminate and shall revert to the Grantors or
their respective successors and assigns, and the estate, right, title and
interest of the Trustee therein shall thereupon cease, terminate and become
void.  In such case, the Grantors shall deliver to the Trustee one or more
instruments of discharge, satisfaction and release in form reasonably
satisfactory to the Trustee, and, upon the written request of the Company or its
successors or assigns, and at the cost and expense of the Company or its
successors or assigns, the Trustee shall execute a satisfaction of the Security
Documents and such instruments as are necessary or desirable to terminate and
remove of record any documents constituting public notice of the Security
Documents and the Liens and assignments granted thereunder and shall assign and
transfer, or cause to be assigned and transferred, and shall deliver or cause to
be delivered to each of the Grantors, all property, including all moneys,
instruments and securities of each Grantor, then held by the Trustee.  The

reimbursed for any expenditures which it may thereafter incur in connection
therewith.

Requisite Lenders or the Agent, on behalf of the Requisite Lenders, at the
request of any of the Grantors, instruct the Trustee to release specified
portions of the Collateral pursuant to SECTION 2.3 of this Agreement and in
accordance with SECTION 9.07(c) of the Credit Agreement, all right, title and
interest of the Trustee in, to and under such Collateral and the security
interest of the Trustee therein shall terminate and shall revert to the
applicable Grantor or its successors and assigns, and the estate, right, title
and interest of the Trustee therein shall thereupon cease, terminate and become
void.  Any Grantor's request for any such release shall be accompanied by a
written certification by such Grantor, in form reasonably satisfactory to the
Trustee, that, as of the date of such release, no Actionable Default has
occurred and is continuing.  Following such instructions, the Trustee shall,
upon the written request of such Grantor, its successors or assigns and at the
cost and expense of such Grantor or its successors or assigns, execute such
instruments and take such other actions as are necessary or desirable to
terminate any such security interest and otherwise effectuate the release of the
specified portions of the Collateral from the Lien of such security

                                      -23-

interest.  Such termination and release shall be without prejudice to the rights
of the Trustee or any successor trustee to charge and be reimbursed for any
expenditures which it may thereafter incur in connection therewith.

prior written consent of the Requisite Lenders, the Trustee and the Grantors
may, from time to time, enter into written agreements supplemental hereto for
the purpose of adding to or waiving any provision of this Agreement or any of
the Security Documents or amending the definition of any capitalized term used
herein or therein, as such capitalized term is used herein or therein, or
changing in any manner the rights of the Trustee, the Holders or the Grantors
hereunder or thereunder; PROVIDED, HOWEVER, that no such supplemental agreement
shall:

          (i)  modify the definition of Requisite Lenders without the
     written consent of all Lenders; or

          (ii)  amend, modify or waive any provision of this Agreement or
     any Security Document so as to adversely affect any of the Trustee's
     rights, immunities or indemnities hereunder or thereunder or enlarge
     its duties hereunder or thereunder, without the written consent of the
     Trustee.

Any such supplemental agreement shall be binding upon the Grantors, the Holders
and the Trustee and their respective successors and assigns.  The Trustee shall
not enter into any such supplemental agreement unless it shall have received a
certificate signed by an Authorized Officer of the Company to the effect that
such supplemental agreement will not result in a breach of any provision or
covenant contained in the Credit Agreement, any of the Public Indentures or any
of the Refinancing Instruments.  Prior to executing any amendment pursuant to
the terms of this SECTION 8.1(a), the Trustee shall be entitled to receive an
opinion of counsel to the effect that the execution of such document is
authorized hereunder.

          (b)  Without the consent of the Holders, at any time and from time to
time, with the consent of the Agent, the Grantors and the Trustee may enter into
additional Security Documents or one or more agreements supplemental hereto or
to any Security Document, in form satisfactory to the Trustee:

          (i)  to add to the covenants of the Grantors for the benefit of
     the Holders;

          (ii)  to mortgage, pledge or grant a security interest in favor
     of the Trustee as additional security for the Secured Debt pursuant to
     any Security Document; or

          (iii)  to cure any ambiguity or to correct or supplement any
     provision herein or in any Security Document which may be defective or
     inconsistent with any other provision herein or therein; PROVIDED,
     HOWEVER, that any such action contemplated in this CLAUSE (iii) shall
     not adversely affect the interests of the Holders in any manner
     whatsoever.

          (c)  Without the consent of the Holders, the Grantors and the Trustee
may, at the direction of the Agent and at any time and from time to time, add
additional Persons ("ADDITIONAL GRANTORS") to this Agreement, or any of the
Security Documents, and such additional provisions hereto and thereto as may be
necessary or appropriate to effect the grant by such Additional Grantors of
Liens on any assets of such Additional Grantors as additional

                            COMPANY PLEDGE AGREEMENT


          THIS COMPANY PLEDGE AGREEMENT (this "AGREEMENT") dated as of July ___,
1995 by and among USG CORPORATION, a Delaware corporation (the "PLEDGOR"),
WILMINGTON TRUST COMPANY, a Delaware banking corporation ("WILMINGTON"), and
WILLIAM J. WADE ("WADE"), Wilmington and Wade acting not in their individual
capacities, but solely as trustees (collectively and individually, the
"TRUSTEE") under the "Collateral Trust Agreement" referred to below.  Terms
capitalized and used herein which are not otherwise defined herein shall have
the meanings given them in the Collateral Trust Agreement.

                              W I T N E S S E T H:

          WHEREAS, the Pledgor is party to that certain Credit Agreement dated
as of July 26, 1995 (as the same may be amended, restated, supplemented or
otherwise modified from time to time, the "CREDIT AGREEMENT") with the financial
institutions from time to time party thereto (the "LENDERS") and Chemical Bank,
in its separate capacity as agent for the Lenders (in such capacity, the
"AGENT");

          WHEREAS, in connection with the Credit Agreement, the Pledgor has
entered into that certain Collateral Trust Agreement dated as of July 26, 1995
(as the same may amended, restated, supplemented or otherwise modified from time
to time, the "COLLATERAL TRUST AGREEMENT");

          WHEREAS, in connection with the Collateral Trust Agreement, and in
order to secure the prompt and complete payment, observance and performance of
the Secured Debt, the Pledgor and the Trustee have agreed to enter into this
Agreement; and

          WHEREAS, the Pledgor is the owner of the issued and outstanding shares
of capital stock of the subsidiaries listed on EXHIBIT A attached hereto and
made a part hereof (the "SUBSIDIARIES");

          NOW, THEREFORE, for and in consideration of the foregoing and of any
financial accommodations or extensions of credit (including, without limitation,
any loan or advance by renewal, refinancing or extension of the agreements
described hereinabove or otherwise) heretofore, now or hereafter made to or for
the benefit of the Pledgor by any of the Lenders or Issuing Banks in connection
with the transactions contemplated by the Credit Agreement, and for other good
and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto hereby agree as follows:

          1.  GRANT OF SECURITY INTEREST.  The Pledgor hereby grants to the
Trustee for the equal and ratable benefit of the Secured Parties, as security
for the prompt and complete payment, observance and performance of all of the
Secured Debt, a security interest in (a) all shares of the capital stock of the
Subsidiaries now or at any time or times hereafter owned by Pledgor (the
"PLEDGED SHARES"), (b) all warrants, options and other rights to acquire capital
stock of the Subsidiaries now or at any time or times hereafter owned by the
Pledgor (the "RIGHTS"), and (c) all proceeds thereof (the Pledged Shares, the
Rights together with the "POWERS" (as defined below), the property and interests
in property described in PARAGRAPHS 7 and 8 below, dividends and distributions
payable with respect to the Pledged Shares that are required to be deposited in
the Collateral Account pursuant to PARAGRAPH 4 below, and all proceeds of any of
the foregoing, being hereinafter collectively referred to as the "PLEDGED
COLLATERAL").  The Pledgor agrees to execute and deliver to the Trustee (i)
stock powers in the form of EXHIBIT B attached hereto and made

<PAGE>

a part hereof, appropriately endorsed in blank, with respect to the Pledged
Shares and any warrants or options for the purchase of capital stock of the
Subsidiaries included in the Rights, and (ii) such other documents of transfer
as the Trustee may from time to time reasonably request to enable the Trustee
(when and as permitted under the Collateral Trust Agreement) to transfer the
Pledged Shares and the Rights into its name or the name of its nominee (all of
the foregoing being hereinafter referred to as the "POWERS").

          2.  PERFECTION OF SECURITY INTEREST.  The Pledgor agrees (i) to
deliver immediately to the Trustee or the Trustee's nominee all certificates
evidencing any of the Pledged Collateral which may at any time come into the
possession of Pledgor, (ii) to execute and deliver to the Trustee such financing
statements as the Trustee may request with respect to the Pledged Collateral,
and (iii) to take such other steps as the Trustee may from time to time
reasonably request to perfect the Trustee's security interest in the Pledged
Collateral under applicable law.  The Pledgor further agrees, at the reasonable
request of the Trustee, to use its best efforts to cause the Subsidiaries to
issue, in substitution for existing certificates evidencing any of the Pledged
Collateral, one or more new certificates ("SUBSTITUTE CERTIFICATE(S)") intended
to evidence all of the Pledged Collateral evidenced by the certificates which
are exchanged for the Substitute Certificate(s), and the Pledgor shall
immediately thereafter deliver such Substitute Certificates to the Trustee,
together with attached Powers.  The Pledgor agrees that this Agreement or a
photocopy of this Agreement shall be sufficient as a financing statement.

          3.  VOTING RIGHTS.  During the term of this Agreement, and so long as
no Notice of Actionable Default has been given and has not been withdrawn
pursuant to the Collateral Trust Agreement, and the Trustee has not given the
notice referred to in the final sentence of this PARAGRAPH 3, the Pledgor shall
have the right to vote the Pledged Shares and exercise any voting rights
pertaining to the Pledged Collateral (which may, subject to any registration of
the Trustee's security interest pursuant to PARAGRAPH 2 above, be registered on
the books and records of the Subsidiaries in the Pledgor's name except as
otherwise provided in PARAGRAPH 12 below), and to give consents, ratifications
and waivers with respect thereto for all purposes not prohibited by the terms of
the Credit Agreement, the Collateral Trust Agreement or any of the other "LOAN
DOCUMENTS" (as defined in the Credit Agreement).  The Trustee shall, at the
request of the Pledgor, provide the Pledgor with appropriate proxies and any
other documents necessary or appropriate to permit the Pledgor to exercise the
rights set forth in the preceding sentence.  Upon or at any time after the
giving of a Notice of Actionable Default and during the time any Notice of
Actionable Default which has been given has not been withdrawn pursuant to the
Collateral Trust Agreement, the Trustee shall be entitled, at the Trustee's
option and following written notice from the Trustee to the Pledgor, to exercise
all voting powers pertaining to the Pledged Collateral.

          4.  DIVIDENDS AND OTHER DISTRIBUTIONS.  Upon receipt of notice in
accordance with Section 3.1 of the Collateral Trust Agreement that the Trustee
has received a Notice of Actionable Default, the Pledgor shall, at the written
request of the Requisite Lenders, send a written notice (a "DIVIDENDS AND
DISTRIBUTIONS NOTICE") to each of the Subsidiaries specified in such request, no
later than five (5) days after the date of receipt of such request, instructing
such Subsidiaries to remit all dividends and other distributions payable with
respect to the Pledged Collateral (until such time as such Notice of Actionable
Default is withdrawn pursuant to the Collateral Trust Agreement) directly to the
Trustee to be deposited in the Collateral Account as additional Pledged
Collateral, and promptly send a copy of the Dividends and Distributions Notice
to the Agent and the Trustee.  Nothing contained in this PARAGRAPH 4 shall be
deemed to permit the payment of any dividend or the making of any distribution
which is prohibited by the Credit Agreement or any of the other agreements and
documents executed in connection with the transactions contemplated thereby.

<PAGE>

          5.  REPRESENTATIONS.  On the date hereof, the Pledgor warrants and
represents as follows:

          (a)  The Pledgor is the sole, direct, legal and beneficial owner of
     the Pledged Shares, free and clear of any Lien except for the security
     interests created by this Agreement and "PERMITTED LIENS" (as defined in
     Section 6.03 of the Credit Agreement), and such stock has been duly
     authorized and is fully paid and nonassessable;

          (b)  The Pledged Shares constitute the percentage of the issued and
     outstanding capital stock of the Subsidiaries as set forth on EXHIBIT A,
     and there are no Rights associated with such capital stock;

          (c)  The Pledgor has full corporate power and authority to enter into
     this Agreement;

          (d)  There are no restrictions upon the voting rights associated with,
     or the transfer of, any of the Pledged Collateral except as provided by (i)
     the "Securities Act" (as defined in PARAGRAPH 9 of this Agreement), and/or
     (ii) the terms and provisions of the Loan Documents, and/or (iii) any
     restrictions in connection with the Existing Credit Agreement (as such term
     is defined in the Credit Agreement);

          (e)  The Pledgor has the right, subject to the provisions of the Loan
     Documents, (i) to vote the Pledged Collateral, and (ii) to pledge and grant
     a security interest in all or any part of the Pledged Collateral free of
     any Lien;

          (f)  The Pledgor has the right (subject, however, to the Securities
     Act and/or the terms and provisions of the Loan Documents) to transfer all
     or any part of the Pledged Collateral free of any Lien;

          (g)  No authorization, approval, or other action by, and no notice to
     or filing with, any governmental authority or regulatory body which has not
     heretofore been taken or obtained is required either (i) for the pledge of
     the Pledged Collateral pursuant to this Agreement or for the execution,
     delivery or performance of this Agreement by the Pledgor or (ii) for the
     exercise by the Trustee of the voting or other rights provided for in this
     Agreement or the remedies in respect of the Pledged Collateral pursuant to
     this Agreement (except as may be required in connection with any
     disposition thereof by laws affecting the offering and sale of securities
     generally);

          (h)  The pledge of the Pledged Collateral pursuant to this Agreement
     creates a valid and perfected (and, with respect to the Pledged Shares
     only, first priority) security interest in the Pledged Collateral, in favor
     of the Trustee, securing the payment and performance of the Secured Debt;
     and

          (i)  The Powers are duly executed and give the Trustee the authority
     they purport to confer.

          6.  SUBSEQUENT CHANGES AFFECTING PLEDGED COLLATERAL.  The Pledgor
represents to the Trustee that the Pledgor has made its own arrangements for
keeping informed of changes or potential changes affecting the Pledged
Collateral (including, but not limited to, rights to convert, rights to
subscribe, payment of dividends, reorganization or other exchanges, tender
offers and voting rights), and Pledgor agrees that neither the Trustee nor any
Secured Party shall have any responsibility or liability for informing Pledgor
of any such changes or potential changes or for taking any action or omitting to
take any action with respect thereto.

          7.  PLEDGED SHARES ADJUSTMENTS.  In the event that, during the term of
this Agreement, any stock dividend, reclassification, readjustment or

<PAGE>

other change is declared or made in the capital structure of any of the
Subsidiaries (including, without limitation, the issuance of additional shares
of capital stock of any of the Subsidiaries), or any of the Rights are
exercised, or both, then the Trustee shall have a security interest in all new,
substituted and additional shares or other securities issued to or acquired by
the Pledgor by reason of any such change or exercise, and such shares or other
securities shall become part of the Pledged Collateral; PROVIDED, HOWEVER, that
nothing contained in this PARAGRAPH 7 shall be deemed to permit any stock
dividend, issuance of additional stock, reclassification, readjustment or other
change in the capital structure of any of the Subsidiaries which is prohibited
by the Credit Agreement, the Collateral Trust Agreement or any other Loan
Document.

          8.  WARRANTS, OPTIONS AND OTHER RIGHTS.  The Pledgor shall not permit
any Subsidiary to issue any capital stock or Rights, other than in favor of
Pledgor.  In the event that, during the term of this Agreement, any Rights shall
be issued by any of the Subsidiaries in connection with the Pledged Collateral
or otherwise issued to or acquired by the Pledgor, then the Trustee shall have a
security interest in such Rights, and such Rights shall become part of the
Pledged Collateral; PROVIDED, HOWEVER, that nothing contained in this PARAGRAPH
8 shall be deemed to permit the issuance of any warrants or other rights or
options by any of the Subsidiaries which is prohibited by the Credit Agreement,
the Collateral Trust Agreement or any other Loan Document.

          9.  REGISTRATION.  Upon or at any time after the giving of a Notice of
Actionable Default and during the time any Notice of Actionable Default which
has been given has not been withdrawn pursuant to the Collateral Trust
Agreement, in the event the Trustee determines to exercise its right to sell the
Pledged Collateral pursuant to PARAGRAPH 12 below, Pledgor shall, upon the
request of Trustee, at Pledgor's expense:

          (a)  execute and deliver, and cause the Subsidiaries, their respective
     officers and directors to execute and deliver, all such instruments and
     documents, and do or cause to be done all such other acts and things, as
     may be necessary or, in the opinion of the Trustee, the Requisite Lenders
     or its or their counsel, advisable to register the Pledged Collateral or
     any part thereof under the provisions of the Securities Act of 1933, as
     from time to time amended (the "Securities Act"), and to cause each
     registration statement relating thereto to become effective and to remain
     effective for such period as prospectuses are required by law to be
     furnished, and to make all amendments and supplements thereto and to the
     related prospectus which, in the opinion of the Trustee, the Requisite
     Lenders or its or their counsel, are necessary or advisable, all in
     conformity with the requirements of the Securities Act and the rules and
     regulations of the Securities and Exchange Commission applicable thereto;

          (b)  use its best efforts to qualify the Pledged Collateral under
     applicable state securities or "Blue Sky" laws and to obtain all necessary
     governmental approvals for the sale of the Pledged Collateral or any
     thereof, as requested by the Trustee or the Requisite Lenders;

          (c)  cause each or any of the Subsidiaries to make available to the
     Pledgor, as soon as practicable, an earnings statement which will satisfy
     the provisions of Section 11(a) of the Securities Act; and

          (d)  do or cause to be done all such other acts and things as may be
     necessary to make such sale of the Pledged Collateral or any part thereof
     valid and binding and in compliance with applicable law.

The Pledgor will reimburse the Trustee for any expense incurred by the Trustee,
including, without limitation, reasonable attorneys' and accountants' fees and
expenses in connection with the foregoing.  Upon or at any time after

<PAGE>

the giving of a Notice of Actionable Default and during the time any Notice of
Actionable Default which has been given has not been withdrawn pursuant to the
terms of the Collateral Trust Agreement, should the Trustee or the Requisite
Lenders reasonably determine that, prior to any public offering of any
securities constituting all or any part of the Pledged Collateral, such
securities should be registered under the Securities Act and/or registered or
qualified under any other federal or state law, and that such registration
and/or qualification is not practical, then the Pledgor agrees that it will be
commercially reasonable to hold a private sale, upon at least five (5) Business
Days' notice to the Pledgor, so as to avoid a public offering, even though the
sales price established and/or obtained at such private sale may be
substantially less than prices which could have been obtained for such security
on any market or exchange or in any other public sale.

          10.  NO DISCHARGE.  The Pledgor shall remain bound and its obligations
hereunder shall be unconditional, irrespective of (i) the subordination of the
Secured Debt or any of the Debt Instruments, (ii) the absence of any attempt to
collect the Secured Debt from any guarantor thereof or other action to enforce
the same or the election of any remedy by the Trustee or any of the Secured
Parties, (iii) the waiver, consent, extension, forbearance or granting of any
indulgence by the Trustee or any of the Secured Parties with respect to any
provision of any of the Debt Instruments, (iv) the failure by the Trustee to
take any steps to perfect and maintain its security interest in, or to preserve
its rights to, any of the Pledged Collateral, (v) the election by any of the
Secured Parties, in any proceeding instituted under Chapter 11 of the Bankruptcy
Code of the application of Section 1111(b)(2) of the Bankruptcy Code, (vi) any
borrowing or grant of a security interest by any Grantor, as
debtor-in-possession, under Section 364 of the Bankruptcy Code, (vii) the
disallowance under Section 502 of the Bankruptcy Code of all or any portion of
the claims of the Secured Parties for repayment of the Secured Debt, or (viii)
any other circumstance which might otherwise constitute a legal or equitable
discharge or defense of a guarantor or of the Pledgor; all of the foregoing
being expressly waived by the Pledgor to the extent permitted by applicable law.

          11.  WAIVERS. To the extent permitted by applicable law, the Pledgor
hereby waives any requirement of diligence, presentment, demand of payment,
filing of claims with a court in the event of receivership or bankruptcy of any
Grantor, protest or notice with respect to the Secured Debt and all demands
whatsoever (and shall not require that the same be made on any other Grantor as
a condition precedent to the Pledgor's obligations hereunder), and covenants
that this Agreement will not be discharged, except as provided in PARAGRAPH 13
hereunder.  Notwithstanding anything to the contrary contained in this
Agreement, the Pledgor does not waive any rights to notice provided to it as the
"Borrower" under the Credit Agreement.

          12.  REMEDIES OF TRUSTEE FOLLOWING A NOTICE OF ACTIONABLE DEFAULT.
The Trustee may, upon or at any time after the giving of a Notice of Actionable
Default and during the time any Notice of Actionable Default which has been
given has not been withdrawn pursuant to the Collateral Trust Agreement, at its
option, transfer or register the Pledged Collateral or any part thereof into its
or its nominee's name with or without any indication that such Pledged
Collateral is subject to the security interest hereunder.  The Pledgor hereby
appoints the Trustee as its attorney-in-fact to arrange at the Trustee's option
for such transfer.  The Trustee shall have, in addition to the foregoing and any
other rights given under this Agreement or by law, all of the rights and
remedies with respect to the Pledged Collateral of a secured party under the
Uniform Commercial Code as in effect in the State of New York.  In addition,
following the receipt by the Trustee of a Notice of Actionable Default, and
during the time any Notice of Actionable Default which has been given has not
been withdrawn pursuant to the terms of the Collateral Trust Agreement, the
Trustee shall have such powers of sale and other powers as may be conferred by
applicable law.  With respect to the Pledged Collateral or any part thereof
which shall then be in or shall thereafter come into the
<PAGE>

possession or custody of the Trustee or which the Trustee shall otherwise have
the ability to transfer under applicable law, the Trustee may, in its sole
discretion, without notice except as specified below, following the giving of a
Notice of Actionable Default and during such time as any Notice of Actionable
Default which has been given has not been withdrawn pursuant to the terms of the
Collateral Trust Agreement, sell or cause the same to be sold at any broker's
board or at public or private sale, in one or more sales or lots, at such price
as the Trustee may deem best, for cash or on credit or for future delivery,
without assumption of any credit risk on the part of the Trustee or any other
Secured Party, and the purchaser of any or all of the Pledged Collateral so sold
shall thereafter own the same, absolutely free from any claim, encumbrance or
right of any kind whatsoever.

          The Trustee will give the Pledgor reasonable notice of the time and
place of any public sale of the Pledged Collateral, or of the time after which
any private sale or other intended disposition is to be made.  Any sale of the
Pledged Collateral conducted in conformity with reasonable commercial practices
of banks, commercial finance companies, insurance companies or other financial
institutions disposing of property similar to the Pledged Collateral shall be
deemed to be commercially reasonable.  Notwithstanding any provision to the
contrary contained herein, any requirements of reasonable notice shall be met if
five (5) Business Days' notice of such sale or disposition is provided to
Pledgor.  Any other requirement of notice, demand or advertisement for sale is,
to the extent permitted by law, waived.  The Trustee or any Secured Party may,
in its own name or in the name of a designee or nominee, buy all or any part of
the Pledged Collateral at any public sale and, if permitted by applicable law,
buy all or any part of the Pledged Collateral at any private sale.  The Pledgor
will pay to the Trustee all expenses (including, without limitation, court costs
and attorneys' and paralegals' fees and expenses) of, or incident to, (i) the
administration of this Agreement, (ii) the custody or preservation of, or the
sale or collection of or other realization upon, any of the Pledged Collateral,
(iii) the exercise or enforcement of any of the rights of the Trustee hereunder,
or (iv) the failure by the Pledgor to perform or observe its duties and
obligations hereunder.  In view of the fact that federal and state securities
laws may impose certain restrictions on the method by which a sale of the
Pledged Collateral may be effected, the Pledgor agrees that upon the giving of a
Notice of Actionable Default and during the time any Notice of Actionable
Default which has been given has not been withdrawn pursuant to the terms of the
Collateral Trust Agreement, the Trustee may, from time to time, attempt to sell
all or any part of the Pledged Collateral by means of a private placement
restricting the bidders and prospective purchasers to those who are qualified
and will represent and agree that they are purchasing for investment only and
not for distribution.  In so doing, the Trustee may solicit offers to buy the
Pledged Collateral, or any part of it, from a limited number of investors deemed
by the Trustee, in its reasonable judgment, to be financially responsible
parties who might be interested in purchasing the Pledged Collateral.  If the
Trustee solicits such offers, then the acceptance by the Trustee of the highest
offer obtained therefrom shall be deemed to be a commercially reasonable method
of disposing of such Pledged Collateral.

          13.  TERM.  This Agreement shall remain in full force and effect until
such time as all of the Pledged Collateral has been released pursuant to the
terms of the Collateral Trust Agreement and the Credit Agreement.  The security
interest under this Agreement in all or any portion of the Pledged Collateral
(the "RELEASED COLLATERAL") may be released pursuant to the terms and provisions
of the Collateral Trust Agreement and the Credit Agreement, and thereupon the
Released Collateral shall no longer be "PLEDGED SHARES" or "PLEDGED COLLATERAL"
as defined and used herein.  The Trustee shall promptly take all steps Pledgor
may reasonably request to release its security interest in the Released
Collateral, as required by Section 7.4 of the Collateral Trust Agreement.

          14.  TRUSTEE'S EXERCISE OF RIGHTS AND REMEDIES UPON RECEIPT OF A

<PAGE>

NOTICE OF ACTIONABLE DEFAULT.  Notwithstanding anything set forth herein to the
contrary, it is hereby expressly agreed that, upon the Trustee's receipt of a
Notice of Actionable Default, the Trustee may, and upon the written direction of
the Requisite Lenders shall, exercise any of the rights and remedies provided in
this Agreement, the Collateral Trust Agreement or any other "COLLATERAL
DOCUMENT" (as defined in the Credit Agreement).

          15.  DEFINITIONS. The singular shall include the plural and vice versa
and any gender shall include any other gender as the context may require.

          16.  SUCCESSORS AND ASSIGNS.  This Agreement shall be binding upon and
inure to the benefit of the Pledgor, the Trustee and their respective successors
and assigns.  The Pledgor's successors and assigns shall include, without
limitation, a receiver, trustee or debtor-in-possession of or for the Pledgor.

          17.  APPLICABLE LAW.  This Agreement shall be governed by and
construed in accordance with the laws of the State of New York.  Whenever
possible, each provision of this Agreement shall be interpreted in such manner
as to be effective and valid under applicable law, but if any provision of this
Agreement shall be held to be prohibited or invalid under applicable law, such
provision shall be ineffective only to the extent of such prohibition or
invalidity, without invalidating the remainder of such provision or the
remaining provisions of this Agreement.

          18.  FURTHER ASSURANCES.  The Pledgor agrees that it will cooperate
with the Trustee and will execute and deliver, or cause to be executed and
delivered, all such other stock powers, proxies, instruments, documents and
resignations of officers and directors, and will take all such other action,
including, without limitation, the filing of financing statements, as the
Trustee may reasonably request from time to time in order to carry out the
provisions and purposes hereof.

          19.  CONSENT TO JURISDICTION AND SERVICE OF PROCESS.  All judicial
proceedings brought against the Pledgor with respect to this Agreement may be
brought in any state or federal court of competent jurisdiction in the state of
New York, and by execution and delivery of this Agreement, the Pledgor accepts,
for itself and in connection with its properties, generally and unconditionally,
the nonexclusive jurisdiction of the aforesaid courts, and irrevocably agrees to
be bound by any final judgment rendered thereby in connection with this
Agreement from which no appeal has been taken or is available.  The Pledgor
irrevocably consents to the service of process of any of the aforementioned
courts in any such action or proceeding by the mailing of copies thereof by
registered or certified mail, postage prepaid, to its notice address specified
on the signature pages hereof, such service to become effective ten (10) days
after such mailing.  The Pledgor irrevocably waives any objection (including,
without limitation, any objection to the laying of venue or based on the grounds
of forum non conveniens) which it may now or hereafter have to the bringing of
any such action or proceeding with respect to this Agreement in any jurisdiction
set forth above.  Nothing herein shall affect the right to serve process in any
other manner permitted by law or shall limit the right of any Secured Party to
bring proceedings against the Pledgor in the courts of any other jurisdiction.

          20.  WAIVER OF JURY TRIAL.  EACH OF THE PLEDGOR AND THE TRUSTEE WAIVES
ANY RIGHT TO TRIAL BY JURY IN ANY DISPUTE, WHETHER SOUNDING IN CONTRACT, TORT,
OR OTHERWISE, BETWEEN THE TRUSTEE AND THE PLEDGOR ARISING OUT OF OR RELATED TO
THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT OR ANY OTHER INSTRUMENT,
DOCUMENT OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH.  EITHER THE
PLEDGOR OR THE TRUSTEE MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS
AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES
HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

<PAGE>

          21.  TRUSTEE APPOINTED ATTORNEY-IN-FACT.  The Pledgor hereby appoints
the Trustee as the Pledgor's attorney-in-fact, with full authority in the place
and stead of the Pledgor and in the name of the Pledgor or otherwise, following
the Pledgor's receipt of a Notice of Actionable Default that has not been
withdrawn pursuant to the Collateral Trust Agreement, to take any action and to
execute any instrument which the Trustee may deem necessary or advisable to
accomplish the purposes of this Agreement, in the Trustee's discretion,
including, without limitation, to receive, endorse and collect all instruments
made payable to the Pledgor representing any distribution, interest payment or
other dividend distribution in respect of the Pledged Collateral or any part
thereof to the extent required to be deposited into the Collateral Account in
accordance with Section 4.1 of the Collateral Trust Agreement and to give full
discharge for the same.  This power of attorney created under this PARAGRAPH 21,
being coupled with an interest, shall be irrevocable for the term of this
Agreement and thereafter as long as any of the Secured Debt shall be
outstanding, but shall not be deemed to authorize the Trustee to take any action
which the Pledgor could not be required to take hereunder.

          22.  TRUSTEE'S DUTY.  The Trustee shall not be liable for any acts,
omissions, errors of judgment or mistakes of fact or law including, without
limitation, acts, omissions, errors or mistakes with respect to the Pledged
Collateral, except for those arising out of or in connection with the Trustee's
(i) gross negligence, bad faith or willful misconduct, or (ii) failure to use
reasonable care with respect to the safe custody of any certificate evidencing
any of the Pledged Collateral which is in the physical possession of the
Trustee.  Without limiting the generality of the foregoing, the Trustee shall be
under no obligation to take any steps necessary to preserve rights in the
Pledged Collateral against any other parties but may do so at its option, and
all expenses incurred in connection therewith shall be for the sole account of
the Pledgor, and shall be added to the Secured Debt secured hereby.

          23.  NOTICES.  Any notice or other communication herein required or
permitted to be given shall be in writing and may be personally served,
telecopied, telexed or sent by courier service or United States mail and shall
be deemed to have been given when delivered in person or by courier service,
upon receipt of a telecopy or telex or five (5) Business Days after being
deposited in the United States mail (registered or certified mail, with postage
prepaid and properly addressed).  For the purposes hereof, the addresses of the
parties hereto (until notice of a change thereof is delivered as provided in
this paragraph) shall be as set forth below each party's name on the signature
pages hereof, or, as to each party, at such other address as may be designated
by such party in a written notice to each of the other parties.

          24.  COUNTERPARTS.  This Agreement may be executed in separate
counterparts, each of which shall be an original and all of which taken together
shall constitute one and the same instrument.

          25.  PARAGRAPH HEADINGS.  The paragraph headings herein are for
convenience of reference only, and shall not affect in any way the
interpretation of any of the provisions hereof.

<PAGE>

          IN WITNESS WHEREOF, the Pledgor and the Trustee have executed this
Agreement as of the day first above written.
