14, 2000, is hereby amended by amending Item 1 "Financial  Statements" of Part I

involving  the entries  for the  quarter and six months  ended June 30, 2000 and
1999 for the line item "NET SALES" on the Consolidated Statement of Income. This
transposition resulted from an undetected error in the software program used for
converting the Form 10-Q to EDGAR filing format.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
                                   (unaudited)
2.    GENERAL

The financial  statements  included in this Report are condensed and  unaudited,
pursuant  to  certain  Rules and  Regulations  of the  Securities  and  Exchange
Commission,  but include, in the opinion of the Company,  adjustments  necessary
for a fair statement of the results for the periods indicated,  which,  however,
are not  necessarily  indicative  of results  which may be expected for the full
year.

In connection with the condensed financial statements and notes included in this
Report,  reference  is  made  to the  financial  statements  and  notes  thereto
contained in the  Company's  1999 Annual  Report on Form 10-K, as filed with the
Securities and Exchange Commission.

3.    RESTRUCTURING OF OPERATIONS AND OTHER ACTIONS

During 1997 and 1998,  the Company  recorded  pretax charges of $386 million for
restructuring and other actions to implement the Company's  announced program to
close manufacturing  facilities,  enhance manufacturing  productivity and reduce
overhead.  Of the total pretax charge of $386 million, $143 million was recorded
in the fourth quarter of 1997 and the remaining $243 million was recorded during
1998.

The $386 million pretax charge was comprised of a $185 million charge associated
with the  restructuring  of the Company's  business  segments and a $201 million
charge  associated  with asset  impairments,  including  investments  in certain
affiliates.  The components of the restructuring charge include $115 million for
personnel   reductions;   $68  million  for  the  divestiture  of  non-strategic
businesses  and  facilities,  of which $52 million  represented  non-cash  asset
revaluations,  $16  million  for exit cost  liabilities,  primarily  for  leased
warehouse  and office  facilities  that were  vacated;  and $2 million for other
actions. The divestiture of non-strategic businesses and facilities included the
closure of the Candiac, Quebec manufacturing facility. During the second quarter
of 1999,  the Candiac  manufacturing  facility  was  re-opened  in order to meet
market demands.

The $115 million for personnel reductions represented severance costs associated
with the elimination of  approximately  2,450 positions  worldwide.  The primary
groups affected included manufacturing and administrative  personnel. As of June
2000,  approximately  $103 million has been paid and charged against the reserve
for personnel  reductions.  Charges of approximately  $13 million have been made
against exit cost  liabilities  through June 2000. No adjustments have been made
to the liabilities.

The  following  table   summarizes  the  status  of  the  liabilities  from  the
restructure   program  described  above,   including   cumulative  spending  and
adjustments and the remaining balance as of June 30, 2000:

3.    RESTRUCTURING OF OPERATIONS AND OTHER ACTIONS (continued)

The Company continually evaluates whether events and circumstances have occurred
that  indicate  that  the  carrying  amount  of  certain  long-lived  assets  is
recoverable.  When factors  indicate that a long-lived asset should be evaluated
for  possible  impairment,   the  Company  uses  an  estimate  of  the  expected
undiscounted  cash flows to be generated  by the asset to determine  whether the
carrying amount is recoverable or if an impairment exists. When it is determined
that an impairment  exists, the Company uses the fair market value of the asset,
usually  measured by the discounted  cash flows to be generated by the asset, to
determine  the  amount  of  the  impairment  to be  recorded  in  the  financial
statements.

4.    ACQUISITIONS AND DIVESTITURES OF BUSINESSES

On May 31,  2000,  the  Company  completed  the  sale of its  European  Building
Materials business to an unconsolidated joint venture, Alcopor Owens Corning, in
which  the  Company  has a 40%  interest.  Proceeds  from the  sale,  net of the
Company's $34 million cash infusion into the joint  venture,  were $177 million.
In connection  with this  transaction,  the joint venture assumed $62 million of
debt from Owens  Corning  and the  Company  incurred  fees of  approximately  $6
million,  resulting in net cash proceeds of approximately $109 million. A pretax
gain of approximately $5 million, including a $54 million write-off of goodwill,
was  realized  from the sale.  This pretax gain was  recorded as a reduction  of
other operating expenses on the consolidated statement of income.

The results of  operations  of the  European  Building  Materials  business  are
reflected in the Company's  consolidated  statement of income through the period
ending May 31,  2000.  For the six months ended June 30, 2000 and the year ended
December 31, 1999, the European  Building  Materials  business recorded sales of
approximately  $88  million  and $234  million,  respectively,  and income  from
operations of approximately $1 million and $12 million, respectively.  Effective
May 31, 2000, the Company  accounts for its ownership  interest in Alcopor Owens
Corning under the equity method. Please see Note 1 to the Consolidated Financial
Statements.

During the first quarter of 2000,  the Company  completed the sale of the assets
of Falcon Foam, a producer of foam  insulation in Michigan and  California.  Net
proceeds  from the sale  were  $50  million  and  resulted  in a pretax  loss of
approximately $5 million,  including a $32 write-off of goodwill.  This loss was
recorded as other operating  expenses on the  consolidated  statement of income.
During the first  quarter of 2000,  the Company also  realigned its vinyl siding
manufacturing  operations,  resulting  in the closure of its Fair  Bluff,  North
Carolina  manufacturing  plant. This realignment resulted in a $9 million pretax
expense,  all  of  which  was  recorded  as  other  operating  expenses  on  the
consolidated statement of income.

In connection  with a proposal  received from its Korean joint venture  partner,
the  Company  infused  approximately  $29  million of cash into this  venture in
March, 1999. As a result of this investment,  along with additional  investments
by the other  partner,  the Company  increased its  ownership  interest in Owens
Corning  Korea to 70%.  The Company  accounted  for this  transaction  under the
purchase  method of  accounting  whereby  the assets  acquired  and  liabilities
assumed,  including $84 million in debt, have been recorded at their fair values
and  the  results  of  operations  have  been  consolidated  since  the  date of
acquisition.  Prior to that date,  the Company  accounted for this joint venture
under the equity method.

5.     LONG-TERM DEBT

During the first quarter of 1999, the Company issued $250 million of senior debt
securities  ("the  securities") as unsecured  obligations of the Company.  These
securities,  which  mature in 2009,  bear an annual  rate of  interest  of 7.0%,
payable  semiannually.  The proceeds from the issuance of these  securities were
used to  reduce  borrowings  under  the  Company's  long-term  revolving  credit
agreement.

9.    COMPREHENSIVE INCOME

The Company's comprehensive income for the quarters ended June 30, 2000 and 1999
was a loss of $434 million and income of $76 million,  respectively. For the six
months  ended June 30,  2000 and 1999,  comprehensive  income was a loss of $401
million and income of $109 million,  respectively.  The Company's  comprehensive
income includes net income, currency translation adjustments, and deferred gains
and losses on certain hedging transactions.

The  comprehensive  loss for the  quarter  and six months  ended  June 30,  2000
includes a  reclassification  from other  comprehensive  income to net income of
approximately   $13  million.   This   reclassification   reflects  the  expense
recognition of currency translation  adjustments  resulting from the sale of the
European Building Materials business to Alcopor Owens Corning (see Note 4).

11.   CONTINGENT LIABILITIES

Asbestos Liabilities
--------------------

ITEM A. - OWENS CORNING (EXCLUDING FIBREBOARD)

Numerous  claims have been  asserted  against Owens  Corning  alleging  personal
injury arising from inhalation of asbestos fibers. Virtually all of these claims
arise out of Owens Corning's manufacture,  distribution, sale or installation of
an  asbestos-containing  calcium silicate,  high temperature insulation product,
the  manufacture and  distribution  of which was  discontinued in 1972. The vast
majority of these  claims are being  resolved  through the  National  Settlement
Program described below. As a result of this program, the number of new lawsuits
filed against Owens Corning has been sharply reduced from historical levels, and
compared to other co-defendants in the litigation.

National Settlement Program
---------------------------

Beginning in late 1998,  Owens  Corning has  implemented  a National  Settlement
Program ("NSP") to resolve  personal  injury asbestos claims through  settlement
agreements with individual  plaintiffs' law firms.  The number of  participating
law firms has expanded from approximately 50 when the NSP was established to 117
as of June 30, 2000. The NSP continues to expand.  The NSP is designed to better
manage Owens Corning's  asbestos  liability,  and that of Fibreboard (see Item B
below),  and to help  Owens  Corning  better  predict  the  timing and amount of
indemnity payments for both pending and future claims.

Under the NSP, each participating law firm has agreed to a long-term  settlement
agreement  ("NSP  Agreement")  that  extends  through  at  least  2008.  All NSP
Agreements  provide for the  resolution of asbestos  claims,  including  unfiled
claims,  pending with a participating law firm at the time it enters into an NSP
Agreement ("Initial Claims") and also establishes  procedures and fixed payments
for  resolving   without   litigation  those  claims  that  may  arise  after  a
participating firm enters into an NSP Agreement ("Future Claims") against either
Owens Corning or Fibreboard,  or both. The NSP is designed to allow both holders
of Initial Claims and Future Claims to receive prompt payment without  incurring
the significant  delays and  uncertainties  of litigation,  while enabling Owens
Corning and Fibreboard to manage their  respective  businesses  predictably  and
efficiently.

Terms and Conditions of NSP Agreements
--------------------------------------

Settlement  amounts for both Initial and Future Claims have been negotiated with
each  participating  firm,  and each firm has  communicated  with its respective
current clients to obtain  authority to settle  individual  claims.  Payments to
each  claimant  may vary based on a number of  factors,  including  the type and
severity of disease, age and occupation. All payments are subject to delivery of
satisfactory  evidence of a qualifying  medical  condition and exposure to Owens
Corning's and/or Fibreboard's  products,  delivery of customary releases by each
claimant, and other conditions. Certain claimants settling non-malignancy claims
with  Owens  Corning  and/or  Fibreboard  are or will be  entitled  to an agreed
pre-determined  amount of additional  compensation  if they later develop a more
severe asbestos-related medical condition.

11.   CONTINGENT LIABILITIES

ITEM A. - OWENS CORNING (EXCLUDING FIBREBOARD)  (continued)

As to Future Claims,  each  participating  NSP firm has agreed  (consistent with
applicable  legal  requirements)  to recommend to its future  clients,  based on
appropriately   exercised  professional  judgment,  to  resolve  their  asbestos
personal  injury  claims  against  Owens Corning  and/or  Fibreboard  through an
administrative  processing arrangement,  rather than litigation.  In the case of
Future Claims involving non-malignancy,  claimants must present medical evidence
of functional  impairment,  as well as the product  exposure  criteria and other
requirements set forth above, to be entitled to compensation.

Owens  Corning  and  Fibreboard  (see Item B below)  each  retains  the right to
terminate  any  individual  NSP  Agreement  if in any year more than a specified
number of plaintiffs  represented by the plaintiffs' firm in question reject and
ultimately  opt out of such  agreement.  Opt out procedures are specified in the
settlement agreements,  and provide for mediation and further negotiation before
a claimant  may pursue his or her case in the court  system.  Through June 2000,
fewer  than 200  claimants  have  elected  to  reject  the  original  settlement
proposal, and to mediate under the terms of the NSP Agreement.

As of June 30, 2000, Owens Corning has settled, through the NSP, a total of more
than  237,000  Initial  Claims.  To date,  Owens  Corning  has paid more than $1
billion (including Administrative Deposits as described below) of the settlement
amounts  payable under the NSP in  connection  with these  Initial  Claims;  the
balance  is  scheduled  to  be  paid  as  part  of  Owens  Corning's   estimated
asbestos-related  payments through 2004 (described below under "Asbestos-Related
Payments").  Through July 2000, Owens Corning has received  approximately  1,300
Future Claims under the NSP for payment in 2003,  provided that such claims meet
the  criteria  for  payment  under the NSP  Agreements.  If all such claims were
approved for payment, estimated payments for those claims would be less than $50
million.

Claims approval and payments to claimants for both Initial and Future Claims are
being  managed  by  Integrex,  a  wholly-owned  Owens  Corning  subsidiary  that
specializes in, among other things, claims processing.

NSP Initial Claims Payment Schedules
------------------------------------

Payments  under the NSP for Initial  Claims will generally be made through 2004.
It is anticipated  that payments for a limited number of "exigent" Future Claims
(principally  those of living malignancy  claimants) will continue to be made as
promptly as possible, limited by Owens Corning's available cash flow.

In addition to the right to defer payments for Future Claims as described below,
Owens Corning has requested that NSP participating firms agree to defer payments
in 2000  through 2002 on Initial  Claims to the extent  necessary to ensure that
Owens  Corning  limits  its total  asbestos-related  payments  to the  following
schedule:  $950 million in 2000,  $400 million in 2001, and $250 million in 2002
("Deferral  Program").  An  Executive  Committee  appointed  by the NSP firms to
consider  the  request,   conduct   appropriate   due  diligence,   and  make  a
recommendation  concerning  the program  has agreed to  recommend  the  Deferral
Program.  To facilitate  implementation of the Deferral  Program,  each NSP firm
will receive a revised  payment  schedule.  The Deferral  Program is designed to
facilitate  continued  predictability  and manageability of Owens Corning's cash
flow, while taking into account the ongoing  expansion of the NSP, the timing of

expected future  insurance  recoveries,  efficient tax planning,  and compliance
with ongoing loan  covenants.  On the basis of  preliminary  information,  Owens
Corning  estimates  that the  Deferral  Program  may result in the  deferral  of
approximately $500 million of anticipated NSP payments.  As part of the Deferral
Program,  Owens Corning has agreed to pay any such deferred amounts in two equal
installments in 2003 and 2004, subject to then applicable loan covenants.

NSP Future Claims Payment Schedules
------------------------------------

Payments for other qualifying Future Claims will begin in 2003, and will be made
on the  following  schedule,  based on when such  claims are  accepted  by Owens
Corning for payment:

-------------------------------------------------------- ----------------------------------------------------
</TABLE>

The  schedule  of payments  provided  for  qualifying  Future  Claims  under NSP
Agreements  that have been  entered  into during the fourth  quarter of 1999 and
thereafter  will be delayed by at least one year from the dates for  payment set
forth above.

Pursuant to existing NSP  Agreements,  if, in any calendar year after 2002,  the
payment of any amounts  under the NSP in respect of Future  Claims  would not be
permitted under Owens  Corning's then  prevailing loan covenants,  Owens Corning
will have the right to defer  payment of such amounts  until  February 15 of the
following year.  Commencing in 2003,  subject to the variables and uncertainties
discussed below,  Owens Corning expects that its payments for Future Claims will
not exceed $150  million  per year,  plus any  amounts  payable  pursuant to the
Deferral Program discussed above. Additional settlement payments will be made by
Fibreboard (see Item B below).

Non-NSP Claims
--------------

As of June 30, 2000,  approximately  27,000 asbestos personal injury claims were
pending  against  Owens  Corning  outside  the NSP.  Owens  Corning  notes  that
information  necessary to allow critical  evaluation of these claims,  including
the nature  and  severity  of disease  and  definitive  identifying  information
concerning the claimant,  typically becomes available only through the discovery
process or as a result of settlement  negotiations,  often not  occurring  until
years after the claim is filed. In view of the  indefiniteness  of the available
information,  the  actual  number of  pending  claims  may vary from the  number
indicated.  From the information available, it appears that fewer than 5 percent
of the claims in this non-NSP backlog are mesothelioma  claims.  However,  Owens
Corning  cautions that the number of new  mesothelioma  filings from non-NSP law
firms, including new firms without prior asbestos litigation experience, exceeds
those filed by NSP firms during the same period.

11.   CONTINGENT LIABILITIES

ITEM A. - OWENS CORNING (EXCLUDING FIBREBOARD)  (continued)

From the beginning of 1999 through June 30, 2000, Owens Corning has resolved (by
settlement or otherwise)  approximately  6,000 asbestos  personal  injury claims
outside the NSP. Generally, these claims were settled as they were scheduled for
trial, and typically involved more serious injuries and diseases.

During the  implementation  of the NSP,  Owens  Corning has  attempted to settle
individual non-NSP claims for payments generally consistent with payments to NSP
claimants.  Such settlements are preferable to trials,  provided that the agreed
settlement is fair in relation to similarly situated NSP claimants, because both
the timing and amount of such payments are more predictable. Owens Corning notes
that,  since late 1999,  it has  received a number of  settlement  demands  from
non-NSP plaintiffs'  counsel which have exceeded historical  settlement averages
for like cases. In the event this trend  continues,  and Owens Corning is unable
to reach acceptable settlements, Owens Corning may have to take certain cases to
trial in order to attempt to obtain  fair and  appropriate  resolution  of those
cases,  and  to  pay  settlement  amounts  that  more  closely  approximate  NSP
settlement values. If this strategy is successful, non-participating plaintiffs'
counsel  may  elect to join  the NSP  rather  than  continue  to seek  excessive
settlement values. However, the possibility of adverse verdicts which exceed NSP
settlement  values,  the increased costs of defense and appeals,  and the delays
inherent in litigation, may affect the aggregate payments for non-NSP claims.

Asbestos-Related Payments
-------------------------

In the second quarter of 2000, Owens Corning made  approximately $135 million of
asbestos-related payments, falling within four major categories: (1) Settlements
in respect of verdicts  incurred or claims resolved prior to the  implementation
of the NSP ("Pre-NSP Settlements"); (2) NSP settlements; (3) Non-NSP settlements
covering cases not resolved by the NSP; and (4) Defense,  claims  processing and
administrative expenses, as follows:

Owens Corning has  deposited  certain  amounts in escrow  accounts to facilitate
claims processing under the NSP ("Administrative  Deposits").  Amounts deposited
into escrow in Administrative Deposits during a reporting period are included in
the  payments  shown for NSP  Settlements  during the period.  At June 30, 2000,
approximately $250 million of Administrative  Deposits  previously made by Owens
Corning  had  not  been  finally   distributed   to  claimants   ("Undistributed
Administrative  Deposits")  and,  accordingly,  are reflected in Owens Corning's
consolidated  balance sheet as restricted assets,  under the caption "Restricted
cash",  and have not been subtracted  from Owens Corning's  reserve for asbestos
personal injury claims (discussed below).

11.   CONTINGENT LIABILITIES

ITEM A. - OWENS CORNING (EXCLUDING FIBREBOARD)  (continued)

All  amounts  discussed  above  are  before  tax and  application  of  insurance
recoveries. Owens Corning currently estimates that it will make asbestos-related
payments  (including  Administrative  Deposits)  before tax and  application  of
insurance  recoveries  of  approximately  $950  million  during  2000 (of  which
approximately  $614 million had been made as of June 30),  $400 million in 2001,
$250  million  in 2002 and $400  million in each of 2003 and 2004.  The  amounts
shown for 2003 and 2004 include  $250 million in each year to pay the  estimated
$500 million  amount that may be deferred under the Deferral  Program  described
above.  The actual  amounts of such payments will depend on numerous  variables,
including: (1) the rate at which NSP claims are submitted and processed; (2) the
severity of disease involved in such claims;  (3) the number and type of non-NSP
claims resolved; (4) the cost of resolving such claims, including defense costs;
(5) the amount of insurance recoveries obtained;  and (6) the implementation and
continued applicability of the Deferral Program described above.

held hearings on proposed  legislation  (S 758 and HR 1283)  intended to address
the problem of  asbestos  litigation.  Although  the  original  House and Senate
proposals  were  virtually  identical,  the House has been active in considering
revisions  to HR 1283.  In the  first  quarter  of  2000,  the  House  Judiciary
Committee  approved HR 1283,  amended to protect private settlement plans and to
make such plans enforceable. Owens Corning believes that key members of Congress
view the NSP  favorably  and that,  if any asbestos  legislation  is  eventually
enacted, it will be consistent with the continued implementation of the NSP.

Tax Legislation
---------------

In the spring of 2000,  the United  States House of  Representatives  introduced
proposed legislation (HR 4543) which would exempt investment income earned by an
asbestos-related  trust  from  federal  income  tax,  and would  allow  asbestos
defendants  to  carry-back  net operating  losses  ("NOLs")  created by asbestos
payments  to  the  years  in  which  the  products   containing   asbestos  were
manufactured  in order to obtain a refund of federal  income taxes paid in those
periods.  In the case of Owens  Corning,  this  would  entitle  the  Company  to
carry-back its NOLs to the early 1950s. The exemption of investment income would
benefit the Fibreboard  Settlement Trust (described  below) by having the effect
of enlarging the corpus of the trust through tax-free interest accumulation. The
Senate is  considering a similar bill (S 2955).  There can be no assurance  that
any such legislation will be enacted.

Other Asbestos-Related Litigation
---------------------------------

As previously  reported,  Owens Corning  believes that it has spent  significant
amounts to resolve  claims of asbestos  claimants  whose injuries were caused or
exacerbated by cigarette smoking.  Owens Corning is pursuing  litigation against
tobacco  companies  (discussed  below) to obtain  payment  of  monetary  damages
(including  punitive  damages) for payments made by Owens Corning and Fibreboard
to asbestos claimants who developed smoking related diseases.

11.   CONTINGENT LIABILITIES

ITEM A. - OWENS CORNING (EXCLUDING FIBREBOARD) (continued)

In October 1998,  the Circuit Court for Jefferson  County,  Mississippi  granted
leave to file an amended  complaint in an existing action to add claims by Owens
Corning  against  seven tobacco  companies  and several  other tobacco  industry
defendants.  The court has set a February  2001 trial date for this  action.  In
addition to the Mississippi lawsuit, a lawsuit brought in December 1997 by Owens
Corning and  Fibreboard  is pending in the  Superior  Court for Alameda  County,
California against the same tobacco companies.

Insurance
---------

During  the second  quarter  of 2000,  Owens  Corning  received  a $335  million
settlement  payment  from a  group  of  excess  insurers,  resolving  a  dispute
concerning  coverage  from  such  insurers  for  non-products   asbestos-related
personal injury claims. Of this amount, $125 million had been reflected on Owens
Corning's financial statements as a probable insurance recovery.  The balance of
$210 million was recorded as pre-tax income in the second quarter.

As of June 30, 2000, Owens Corning's financial statements reflect $93 million in
unexhausted insurance coverage (net of deductibles and self-insured  retentions)
under its liability  insurance  policies  applicable to asbestos personal injury
claims.  Most of  this  amount  represents  unconfirmed  potential  non-products
coverage  with excess level  insurance  carriers,  as to which Owens Corning has
estimated its probable  recoveries.  Owens Corning also has a significant amount
of other unconfirmed potential non-products coverage with excess level carriers.
Owens Corning is actively pursuing non-products insurance recoveries under these
policies.  The amount and timing of recoveries  from excess level  policies will
depend on subsequent negotiations and/or proceedings.

Reserve
-------

Owens  Corning  estimates  a  reserve  in  accordance  with  generally  accepted
accounting  principles to reflect  asbestos-related  liabilities  that have been
asserted or are probable of  assertion,  in which  liabilities  are probable and
estimable.  This reserve was established initially through a charge to income in
1991, with additional charges to income of $1.1 billion in 1996 and $1.4 billion
in  1998.  During  the  second  quarter  of 2000,  Owens  Corning  reviewed  the
sufficiency of its provision for asbestos-related liabilities in light of recent
trends  and  developments  in the  administration  of the  NSP  and in  asbestos
litigation generally. These trends and developments included:

o    Additional information obtained in reviewing,  processing and approving for
     payment  more  than  90,000 of the  claims  submitted  under the NSP.  This
     information  allowed Owens Corning to better determine the disease type and
     value of the claims  submitted  under the NSP,  including  the  substantial
     number of claims originally classified as of "unknown" disease type and the
     more  than  60,000  claims  that  have  been  added  to the NSP  since  its
     inception.  As the result of such information,  Owens Corning's estimate of
     the average value of an NSP claim has increased by approximately $2,000.

o    Increased  settlement demands (as described above) and higher than expected
     costs, particularly in 2000, to settle non-NSP claims.

o    Additional  information  from  plaintiffs'  firms as to their  expectations
     concerning the number and nature of future filings.

As the result of its review, Owens Corning increased its asbestos reserves by $1
billion  in  the  second  quarter  of  2000.  The  approximate  balances  of the
components of the reserve at June 30, 2000 are:

</TABLE>

In connection with its asbestos reserve, Owens Corning notes that:

o    The "NSP backlog"  component  represents  the remaining  estimated  cost of
     resolving Initial Claims (as of June 30, 2000) under the NSP. Owens Corning
     is scheduled to pay these costs as part of its  estimated  asbestos-related
     payments through 2004 (described above under "Asbestos-Related Payments").

o    The "Non-NSP backlog" component  represents the estimated cost of resolving
     asbestos  personal  injury claims pending against Owens Corning outside the
     NSP as of June 30, 2000.

o    The "Future  claims"  component  represents the estimated cost of resolving
     (i) Future Claims under the NSP and (ii) non-NSP claims made after June 30,
     2000.

o    The reserve as a whole reflects $250 million of  Undistributed
     Administrative Deposits.

Owens  Corning  cautions  that its estimate of its  liabilities  for pending and
expected  future  asbestos  claims is influenced by numerous  variables that are
difficult  to  predict  and that such  estimate  therefore  remains  subject  to
considerable  uncertainty.  Such variables  include,  among others,  the cost of
resolving  pending  non-NSP  claims;  the disease mix and severity of disease of
pending NSP claims; the number,  severity of disease, and jurisdiction of claims
filed in the future  (especially  the number of mesothelioma  claims);  how many
future claimants are covered by an NSP Agreement;  the extent,  if any, to which
an individual claimant exercises his or her right to opt out of an NSP Agreement
and/or  utilize  counsel not  participating  in the NSP; the extent,  if any, to
which   counsel  that  are  not  bound  by  an  NSP   Agreement   undertake  the
representation of asbestos personal injury plaintiffs against Owens Corning; the
extent,  if any, to which Owens Corning  exercises its right to terminate one or
more of the NSP Agreements due to excessive  opt-outs or for other reasons;  and
Owens  Corning's  success in controlling  the costs of resolving  future non-NSP
claims.

11.   CONTINGENT LIABILITIES

ITEM A. - OWENS CORNING (EXCLUDING FIBREBOARD)  (continued)

As  referenced  above,  Owens  Corning  also notes that in recent  months it has
received a number of settlement demands from non-NSP  plaintiffs'  counsel which
have exceeded historical settlement averages for like cases. In addition,  there
have been recent large  verdict  awards  against  other  asbestos  defendants in
several  jurisdictions,  including  Madison County,  Illinois and Orange County,
Texas.  While the impact of these events to date was  considered  in  connection
with the increase in Owens Corning's asbestos reserves during the second quarter
of 2000 (described above), these events, and the possibility that either or both
will  continue  at  the  same  or  worse  levels,  further  contributes  to  the
uncertainty surrounding Owens Corning's estimate of its liabilities for asbestos
claims.  Recent  bankruptcies  of two other  defendants  in the personal  injury
litigation may also have an adverse impact on future NSP claimants'  willingness
to accept agreed NSP values to resolve  their claims,  as well as on the cost of
resolving future non-NSP claims.

Owens  Corning  will  continue  to  review  the  adequacy  of its  estimates  of
liabilities  and insurance on a periodic basis and make such  adjustments as may
be appropriate.

Management Opinion
------------------

As  described  above,  Owens  Corning has agreed to make  payments  for asbestos
liabilities  through at least 2004. These payments will require  dedication of a
significant  portion of Owens  Corning's  sources of  liquidity  expected  to be
available  during this  period.  Depending  on  operational  cash flow and other
sources of cash, such as insurance recoveries,  divestitures and tax refunds, it
is possible  that Owens  Corning  will  require  additional  financing.  In this
respect, Owens Corning notes that its current $1.8 billion long-term bank credit
facility expires in June 2002. As a result,  such facility will become a current
liability in the second quarter of 2001. Prior to its expiration,  Owens Corning
will need to replace  it, in a similar  or larger  amount,  or obtain  alternate
financing,  on acceptable terms ("Refinancing").  Management believes that it is
likely  that such  Refinancing  will  place  limits  on  payments  for  asbestos
liabilities and may impose other  restrictive  terms and conditions.  Therefore,
accommodations  in addition to the Deferral  Program may be  required.  Although
Owens Corning intends to continue to work with the Executive Committee appointed
by the NSP firms, there can be no assurance that such additional  accommodations
or  other  conditions  of the  Refinancing  will be  acceptable  to  plaintiffs'
attorneys.

In addition to the foregoing risk factors,  Owens Corning notes that, in view of
the  variables  and  uncertainties  described  above,  additional  uninsured and
unreserved  costs may arise out of personal  injury  asbestos  claims,  and such
additional costs may be substantial over time.

11.   CONTINGENT LIABILITIES

ITEM A. - OWENS CORNING (EXCLUDING FIBREBOARD)  (continued)

Although  any  opinion  is  necessarily  judgmental  and  must  be  based  on an
assessment of the variables and  uncertainties  described  above,  provided that
Refinancing can be obtained on acceptable  terms,  NSP firms continue to support
the Deferral  Program and agree to any necessary  additional  accommodations  or
other  conditions  of the  Refinancing,  Owens  Corning is not  required to make
asbestos-related  payments  during  the  period  through  2004 in  excess of its
estimated payments described above under "Asbestos-Related  Payments", and Owens
Corning's  results of operations  do not  deteriorate  significantly  during the
period,  management  believes  that  asbestos-related  costs will not impair the
ability of Owens Corning to meets its obligations.  The process of obtaining the
Refinancing,  obtaining necessary additional accommodations,  and limiting total
asbestos-related  payments  will involve  complex  negotiations  among  numerous
parties with  varying  interests.  Moreover,  many factors not in the control of
Owens Corning affect the Company's financial performance. As a result, there can
be no assurance that the necessary steps will be successfully completed.

ITEM B. - FIBREBOARD (EXCLUDING OWENS CORNING)

Prior to 1972, Fibreboard  manufactured insulation products containing asbestos.
Fibreboard  has since been named as  defendant  in many  thousands  of  personal
injury  claims for  injuries  allegedly  caused by asbestos  exposure.  The vast
majority of these claims are being resolved through the NSP, as described below.

National Settlement Program
---------------------------

Fibreboard  is a  participant  in the NSP and is a party  to the NSP  Agreements
discussed in Item A. The NSP Agreements became effective as to Fibreboard in the
fourth quarter of 1999, when the Insurance  Settlement  (discussed below) became
effective.  The NSP Agreements  settle asbestos  personal injury claims that had
been filed against Fibreboard by participating  plaintiffs' law firms and claims
that could have been  filed  against  Fibreboard  by such  firms  following  the
lifting,  in the third quarter of 1999,  of an  injunction  which had barred the
filing of asbestos  personal  injury claims against  Fibreboard.  As of June 30,
2000,  Fibreboard has settled,  through the NSP,  approximately  200,000 Initial
Claims.  The NSP  Agreements  also provide for the  resolution  of Future Claims
against Fibreboard through the administrative  processing  arrangement described
in Item A. The  timing  of  payments  for  Initial  and  Future  Claims  against
Fibreboard  will be  consistent,  generally,  with the  timing of Owens  Corning
payments, described in Item A.

Insurance Settlement
--------------------

In  1993,  Fibreboard  and two of its  insurers,  Continental  Casualty  Company
("Continental")  and Pacific  Indemnity  Company  ("Pacific"),  entered into the
Insurance  Settlement.  The Insurance  Settlement became effective in the fourth
quarter of 1999 and is final and not subject to appeal.

11.   CONTINGENT LIABILITIES

ITEM B. - FIBREBOARD (EXCLUDING OWENS CORNING) (continued)

Since 1993,  Continental and Pacific paid,  either directly or through an escrow
account funded by them, for  substantially  all  settlements of asbestos  claims
reached  prior to the  initiation of the NSP.  Under the  Insurance  Settlement,
Continental  and Pacific  provided  $1,873  million during the fourth quarter of
1999 to fund Fibreboard's costs of resolving pending and future asbestos claims,
whether under the NSP, in the tort system, or otherwise.

The  Insurance  Settlement  funds  are held in and  invested  by the  Fibreboard
Settlement  Trust and are available to satisfy  Fibreboard's  pending and future
asbestos-related  liabilities.  As of June  30,  2000,  $1,249  million  (net of
outstanding  payables)  was held in the  Fibreboard  Settlement  Trust  and $150
million  was  held  in  Undistributed   Administrative  Deposits  on  behalf  of
Fibreboard.  On an ongoing basis, the funds held in the Trust will be subject to
investment   earnings/losses   and  will  be   reduced  as  applied  to  satisfy
Fibreboard's  asbestos-related  liabilities.  Generally,  it  is  expected  that
payments of Fibreboard's  asbestos-related  liabilities will be paid directly by
the Fibreboard  Settlement Trust on behalf of Fibreboard.  Any  asbestos-related
amounts  paid  directly  by  Fibreboard  are subject to  reimbursement  from the
Trust's assets. Under the terms of the Trust, any of such assets that ultimately
are  not  used  to  fund  Fibreboard's   asbestos-related  liabilities  must  be
distributed to charity.

Funds held in the Fibreboard  Settlement  Trust and  Fibreboard's  Undistributed
Administrative  Deposits are reflected on Owens Corning's  consolidated  balance
sheet as  restricted  assets.  These assets are  reflected as current  assets or
other  assets,  with each category  denoted  "Restricted  cash and  securities -
Fibreboard".  The funds held in the Trust must be expended  either in connection
with  Fibreboard's  asbestos-related  liabilities  or to satisfy the  obligation
under the Trust to  distribute to charity the assets,  if any,  remaining in the
Trust after satisfaction of all such liabilities.  Accordingly,  Owens Corning's
consolidated  balance sheet also  reflects  liabilities  in an aggregate  amount
equal  to  the  funds   held  in  the  Trust  and   Fibreboard's   Undistributed
Administrative  Deposits.   These  liabilities,   denoted  as  "Asbestos-related
liabilities  -  Fibreboard",  are  reflected  as current  or other  liabilities,
depending on the period in which  payment is expected.  At June 30, 2000,  Owens
Corning estimates Fibreboard's  asbestos-related  liabilities at $1,365 million.
This amount  includes an  increase of $99 million  during the second  quarter of
2000 as the result of Owens Corning's  review of  Fibreboard's  asbestos-related
liabilities.  See Note 12 for additional  information  concerning the Fibreboard
Settlement Trust.

Asbestos-Related Payments
-------------------------

In the second  quarter  of 2000,  gross  payments  for  asbestos-related  claims
against  Fibreboard  were   approximately  $249  million,   all  of  which  were
paid/reimbursed  by the Fibreboard  Settlement Trust. These payments fell within
four major categories, as follows:

11.   CONTINGENT LIABILITIES

ITEM B. - FIBREBOARD (EXCLUDING OWENS CORNING) (continued)

The payments for NSP  Settlements  include  Administrative  Deposits  during the
quarter on behalf of Fibreboard. At June 30, 2000, there were approximately $150
million of Undistributed  Administrative  Deposits made on behalf of Fibreboard.
As described above, these Undistributed  Administrative Deposits are included as
restricted  assets,   under  the  caption  "Restricted  cash  and  securities  -
Fibreboard", on Owens Corning's consolidated balance sheet.

In addition to the Deferral Program for Owens Corning asbestos-related  payments
(described in Item A), Owens Corning has requested that NSP participating  firms
agree to modify the Fibreboard NSP payment  obligations so as to slow early year
payments and allow  earnings in the Fibreboard  Settlement  Trust to accumulate.
Owens Corning is currently  working with the NSP Executive  Committee to develop
an acceptable  payment  schedule.  There can be no assurance  that an acceptable
schedule will be agreed upon. Owens Corning currently  estimates that Fibreboard
will incur total asbestos-related  payments (including  Administrative Deposits)
of approximately $700 million in 2000, all of which are  payable/reimbursable by
the Fibreboard  Settlement Trust as described above.  Fibreboard payments beyond
2000 will depend upon  whether an  acceptable  alternative  payment  schedule is
agreed upon.  Fibreboard  payments  will also depend on the same  variables  and
uncertainties as those described above affecting Owens Corning's payments.

Management Opinion
------------------

Owens  Corning  cautions  that its  estimate  of  Fibreboard's  asbestos-related
liabilities  is  influenced  by the same  types of  variables  and is subject to
similar  uncertainty  as in the case of Owens  Corning.  Although any opinion is
necessarily  judgmental  and must be based on an assessment of the variables and
uncertainties described above, Owens Corning believes the amounts available from
the Fibreboard  Settlement Trust will be adequate to fund  Fibreboard's  ongoing
defense and indemnity  costs  associated with  asbestos-related  personal injury
claims for the foreseeable future.

Other Liabilities
-----------------

Various other  lawsuits and claims  arising in the normal course of business are
pending  against  Owens  Corning,  some of  which  allege  substantial  damages.
Management  believes that the outcome of these lawsuits and claims will not have
a materially adverse effect on Owens Corning's  financial position or results of
operations.

12.   FIBREBOARD SETTLEMENT TRUST

Under  the  Insurance  Settlement  described  in Note  11,  two of  Fibreboard's
insurers  provided  $1.873  billion  during the  fourth  quarter of 1999 to fund
Fibreboard's  costs  of  resolving  pending  and  future  asbestos  claims.  The
Insurance Settlement funds are held in and invested by the Fibreboard Settlement
Trust (the "Trust") and are available to satisfy Fibreboard's pending and future
asbestos-related  liabilities.  On an ongoing basis, the funds held in the Trust
will be subject to investment  earnings/losses and will be reduced as applied to
satisfy  Fibreboard's  asbestos  liabilities.  Under the terms of the Trust, any
Trust  assets  which  ultimately  are not  used to  fund  Fibreboard's  asbestos
liabilities must be distributed to charity.

The Trust is a qualified settlement fund for federal income tax purposes, and is
taxed  separately from Owens Corning on its net taxable income,  after deduction
for related administrative expenses.

General Accounting Treatment
----------------------------

The  assets  of the  Trust  are  comprised  of cash  and  marketable  securities
(collectively,   the  "Trust  Assets")  and,  with  Fibreboard's   Undistributed
Administrative  Deposits,  are reflected on Owens Corning's consolidated balance
sheet as  restricted  assets.  These assets are  reflected as current  assets or
other  assets,  with each category  denoted  "Restricted  cash and  securities -
Fibreboard".  The funds held in the Trust must be expended  either in connection
with  Fibreboard's  asbestos-related  liabilities  or to satisfy the  obligation
under the Trust to  distribute to charity the assets,  if any,  remaining in the
Trust after satisfaction of all such liabilities.  Accordingly,  Owens Corning's
consolidated  balance sheet also  reflects  liabilities  in an aggregate  amount
equal  to  the  funds   held  in  the  Trust  and   Fibreboard's   Undistributed
Administrative  Deposits.   These  liabilities,   denoted  as  "Asbestos-related
liabilities  -  Fibreboard,"  are  reflected  as current  or other  liabilities,
depending on the period in which  payment is expected.  At June 30, 2000,  Owens
Corning estimates Fibreboard's  asbestos-related  liabilities at $1.365 billion,
with a residual  obligation  to charity of $34 million.  Payments from the Trust
and   distributions    from    Undistributed    Administrative    Deposits   for
asbestos-related  liabilities reduce both the assets and related  liabilities on
the consolidated balance sheet.

For accounting  purposes,  the Trust Assets are classified  from time to time as
"available  for sale" or "held to maturity"  and are  reported in the  Company's
consolidated  financial  statements in accordance with SFAS No. 115, "Accounting
for Certain Investments in Debt and Equity Securities." Accordingly,  marketable
securities  classified  as available  for sale are recorded at fair market value
and  marketable  securities  designated  as held to  maturity  are  recorded  at
amortized cost.

Any unrealized  increase/decrease  in fair market value is reflected as a change
in the carrying amount of the asset on the consolidated balance sheet as well as
an increase/decrease to other comprehensive income within stockholders'  equity,
net  of  tax.  The   residual   liability  to  be  paid  to  charity  will  also
increase/decrease,  with a  related  decrease/increase  to  other  comprehensive
income within stockholders' equity, net of tax.

Any earnings and realized  gains/losses  on the Trust Assets are reflected as an
increase/decrease  in the  carrying  amount of such  assets on the  consolidated
balance sheet as well as other  income/expense on the consolidated  statement of
income.

The residual liability to be paid to charity will also  increase/decrease,  with
related other expense/ income on the consolidated  statement of income. Cost for
purposes of computing  realized  gains/losses  is determined  using the specific
identification method.

Adjustments
-----------

Periodically,  the Company evaluates the amount of Fibreboard's asbestos-related
liabilities.  During the second  quarter of 2000,  the Company  determined  that
Fibreboard's  asbestos-related  liabilities  required an increase of $99 million
(see Note 11). Accordingly, the Company increased Fibreboard's  asbestos-related
liabilities  and reduced the amount payable to charity by this amount during the
second quarter of 2000.

Results for the Period Ending June 30, 2000
-------------------------------------------

Trust Assets generated  interest/dividend  earnings of approximately $18 million
in the second  quarter  of 2000 and $38  million  year to date,  which have been
recorded as an increase in the carrying  amount of the assets on Owens Corning's
consolidated balance sheet and as other income on the consolidated  statement of
income.  This  income,  however,  has been  offset  by an equal  charge to other
expense,  which represents the increase in the residual  liability to be paid to
charity.

Payments for  asbestos-related  claims from the Trust (including  Administrative
Deposits) during the second quarter of 2000 were  approximately $249 million and
total $634 million for the year.  Such  payments were funded by existing cash in
the  Trust  or  proceeds  from the sale of  securities.  The sale of  securities
resulted  in a net  realized  gain of less than $1  million  during  the  second
quarter of 2000 and  approximately  $1 million year to date.  Realized  gains or
losses from the sale of  securities  are  reflected on the  Company's  financial
statements  in the same  manner as actual  returns  on Trust  Assets,  described
above.

During  2000,  fair  market  value  adjustments  for  securities  designated  as
available  for sale have resulted in a net  unrealized  gain of $1 million since
their  valuation at December 31, 1999. As the investments had an unrealized loss
of  approximately  $1 million at December 31, 1999,  there is no net  unrealized
gain or loss on these investments at June 30, 2000. The gain in the current year
has been reflected in the Company's consolidated balance sheet as an increase to
the carrying amount of the asset and an increase to other comprehensive  income.
This gain has also been reflected as an increase to the charity liability,  with
a corresponding decrease to other comprehensive income.

At June 30, 2000, the fair value of Trust Assets was $1.399 billion,  net of $29
million in  outstanding  payables.  Total trust  assets of $1.278  billion  were
invested   in   marketable   securities.   The  fair   value  of   Undistributed
Administrative  Deposits was $150 million and was held as restricted  cash. $525
million  of these  assets  have been  classified  as a current  asset  while the
remaining securities have been classified as noncurrent assets.

The amortized cost, gross unrealized  holding gains and losses and fair value of
the investment  securities  available for sale at June 30, 2000 and December 31,
1999 are as follows:
