                                   OPERATIONS
 
NOTE: (All per share information in this Item is on a fully diluted basis.)
 
RESULTS OF OPERATIONS
 
 Six Months Ended June 30, 1994
 
  Net income for the second quarter of 1994 was $45 million, or $.95 per share,
an increase of 34% compared to net income of $33 million, or $.71 per share, in
the second quarter of 1993. Net sales were $852 million, a 13% increase
compared to $754 million a year ago.
 
  For the first six months of 1994, Owens-Corning reported net income before
special items of $63 million, or $1.35 per share, compared to net income of $47
million, or $1.04 per share, for the first six months of 1993. The 1994 special
items include an after-tax gain of $123 million, or $2.46 per share, reflecting
a change to the capital method of accounting for the rebuilding of glass
melting facilities, an after-tax charge of $85 million, or $1.70 per share, for
productivity initiatives and other actions, a non-cash, after-tax charge of $10
million, or $.20 per share, to reflect adoption of Statement of Financial
Accounting Standards (SFAS) No. 106, "Employers' Accounting for Postretirement
Benefits Other Than Pensions" (SFAS No. 106), for plans outside the United
States, and a non-cash, after-tax charge of $28 million, or $.56 per share, to
reflect adoption of SFAS No. 112, "Employers' Accounting for Postemployment
Benefits" (SFAS No. 112). The 1993 special items included an after-tax credit
of $26 million, or $.54 per share, for the cumulative effect of adopting SFAS
No. 109, "Accounting for Income Taxes" (SFAS No. 109), offset by an after-tax
charge of $23 million, or $.47 per share, for actions taken to improve the
competitive position of the Company's European businesses. Please see Notes 4,
5, 6, 7 and 8 to the Consolidated Financial Statements of the Company as of
June 30, 1994, incorporated herein by reference.
 
  Net sales were $1.529 billion in the first six months of 1994, compared to
$1.405 billion in the year earlier period. Gross margin for the second quarter
of 1994 increased to 24%, compared to 23% for the prior year's period,
reflecting improved pricing in many of the Company's worldwide markets.
 
  In North America, the Building Products segment benefitted from a 30%
increase in insulation sales compared to the second quarter of 1993. In Europe,
insulation sales continued to exceed the Company's manufacturing capacity in
the region. In order to meet the demand in Europe, the Company acquired the
United Kingdom-based insulation business and the Kitsons distribution business
of Pilkington plc (Pilkington) in June 1994. The Company is also adding a
second production line at its insulation plant in Vise, Belgium. The purchase
price of Pilkington was $110 million and was financed with borrowings from the
Company's newly established $110 million short-term bank credit facility. In
addition, the Company acquired UC Industries, Inc. (UCI), a privately held
United States producer of pink extruded polystyrene foam products for $44
million, consummated by the exchange of 855,556 shares of the Company's common
stock for all the capital stock of UCI. This purchase extends the Company's
line of building products. During the second quarter of 1994, the Company also
established a joint venture to manufacture insulation products in Guangzhou,
China. Please see Note 3 to the Consolidated Financial Statements of the
Company as of June 30, 1994, incorporated herein by reference.
 
  In the composites business, North American sales grew 10%, driven by the
automotive sector and an increase in activity across a broad range of the
Company's industrial markets. The Company activated its Jackson, Tennessee
plant in April 1994 to assist in meeting the demand for reinforcements. The
Company continues to import products from other worldwide operations, at an
added cost, as North American demand for the Company's reinforcements exceeds
capacity in its North American facilities. Volume held steady and pricing
stabilized in the Company's European composites business late in the quarter.
During the second quarter of 1994, the Company dedicated a new joint-venture
manufacturing plant for glass-reinforced plastic pipe in Mochau, Germany.

<PAGE>
 
  The Company's cost of borrowed funds for the second quarter of 1994 was $1
million higher than during the corresponding quarter of the prior year because
of increased borrowing and higher interest rates during the quarter compared to
a year ago.
 
 Fiscal Years 1993, 1992 and 1991
 
  The Company reported net income for 1993 of $131 million, or $2.81 per share,
compared to reported net income of $73 million, or $1.67 per share, and a net
loss of $742 million, or $18.13 per share, in 1992 and 1991, respectively. The
stronger earnings reflected the Company's ongoing productivity programs and
improving economic conditions in the United States. Excluding special items,
1993 net income from ongoing operations was $118 million, or $2.56 per share,
compared to $83 million, or $1.87 per share, in 1992, and $41 million, or $1.01
per share, in 1991.
 
  The special items for 1993 included a) a credit of $26 million, or $.53 per
share, for the cumulative effect of adopting the new accounting standard for
income taxes (SFAS No. 109), b) a one-time gain of $14 million, or $.29 per
share, reflecting a tax benefit resulting from a re-evaluation of deferred
taxes necessitated by the new federal tax law, offset, in part, by c) an $8
million charge, or $.10 per share, for the writedown of the Company's
hydrocarbon ventures to their net realizable value, and d) a $23 million, or
$.47 per share, charge for a restructuring to improve the competitive position
of the Company's European Composites business.
 
  The special items for 1992 included a) a charge of $16 million, or $.22 per
share, for costs related to the reorganization of the Building Products
businesses and centralization of the Company's accounting and information
systems, and b) a net extraordinary gain of $1 million, or $.02 per share,
resulting from the utilization of tax losses, partially offset by a loss on the
early retirement debt. The reorganization in Building Products was designed to
strengthen its focus on customers, enhance its competitive position, and
further improve its efficiency. Please see Notes 2, 4 and 5 to the Consolidated
Financial Statements of the Company as of December 31, 1993, incorporated
herein by reference.
 
  The 1991 special items included charges for uninsured asbestos litigation
claims and the adoption of the accounting standard for other postretirement
benefits (SFAS No. 106). Please see Notes 15 and 19 to the Consolidated
Financial Statements of the Company as of December 31, 1993, incorporated
herein by reference.
 
  Net sales were $2.9 billion in 1993, an increase of $66 million, or 2
percent, from 1992. Excluding the currency exchange impact of a stronger
dollar, 1993 sales increased 4 percent. Sales in 1991 were $2.8 billion.
 
  The Company's Building Products segment benefitted from an improving economy
in North America during 1993. Insulation sales were particularly strong,
increasing nearly ten percent from 1992 as a result of an increase in housing
starts and growth in the "do-it-yourself" market. In response to demand in
Europe, the Company has announced an expansion of its insulation facility in
Vise, Belgium, which is expected to be operational by early 1995. Roofing and
asphalt sales in 1993 were flat compared to 1992 when there was strong
reroofing activity and demand created by storm damage in Texas, Louisiana, and
Florida.
 
  In the second half of 1993, the Company launched a nationwide roll-out of
PINKPLUS (TM), a new Pink Fiberglas (R) insulation product wrapped in pink
polyethylene. In September 1993, the Company introduced AURA(TM), a high R-
value vacuum panel insulation concept.
 
  In 1993, the Company divested its rockwool insulation plant in Guararema,
Brazil, and closed its calcium silicate insulation facility in Berlin, New
Jersey. These businesses did not use core technologies and did not fit the
Company's long-term strategy for profitable growth.
 
  In the Industrial Materials segment, demand for reinforcements during 1993
was strong and exceeded capacity in the Company's North American facilities.

  Economic conditions remained weak in Europe during 1993. The Company does not
expect significant improvement in the European industrial economy in 1994. As a
result of the European restructuring, which is expected to reduce costs and
increase productivity beginning in 1994, Owens-Corning expects to be well
positioned to benefit when the economic upturn does begin.
 
  As part of its growth strategy, Owens-Corning established an Asia/Pacific
unit, headquartered in Hong Kong, with corporate-wide responsibility for
current operations and future developments in that market. The Company also
completed the acquisition of the assets of Vera A/S, a manufacturer of glass-
reinforced plastic pipe in Sandefjord, Norway.
 
  The Company's gross margin percentage of net sales was 22% for 1993, compared
to 21% in both 1992 and 1991. The increase was primarily due to volume and
price increases in the insulation market and productivity improvements,
partially offset by the effects of currency exchange and the cost of importing
products into the United States from the Company's worldwide operations.
Earnings before interest and taxes (EBIT) from ongoing operations increased to
$267 million in 1993, from $229 million in 1992 and $196 million in 1991. As a
percentage of sales, EBIT from ongoing operations increased to 9.1% in 1993,
compared to 8.0% and 7.0% in 1992 and 1991, respectively.
 
  Operating expenses were higher in 1993 due to the charge for the European
restructuring and the write-down of the Company's hydrocarbon ventures to net
realizable value. The Company continued to increase its research and
development spending for long-term projects, placing a greater emphasis on
developing new products and product applications. The decrease in "Other"
expenses in 1992 compared to 1991 reflects reduced charges for stock
appreciation rights, foreign exchange losses, and product liability expenses
related to the Company's non-asbestos products.
 
  The Company continues to evaluate actions to manage rising health care
expenses. During 1993, the Company approved changes in its postretirement
health care plans for retirees and active employees which reduced ongoing
expenses by $18 million for 1993. Approximately three-quarters of the reduction
was reflected in cost of sales and the balance in operating expenses. Please
see Note 15 to the Consolidated Financial Statements of the Company as of
December 31, 1993, incorporated herein by reference.
 
  In 1993, the Company changed its depreciable asset lives for certain assets
to be consistent with industry practice and actual experience. This change
reduced depreciation expense in 1993 and will result in lower ongoing
depreciation expense. Please see Note 6 to the Consolidated Financial
Statements of the Company as of December 31, 1993, incorporated herein by
reference.
 
  Cost of borrowed funds declined by $21 million in 1993 compared to 1992. The
decrease was due to a $95 million reduction in debt since December 31, 1992,
and lower interest rates on the Company's debt. The reduction in debt was
funded by the Company's cash flow from operations. Please see Note 2 to the
Consolidated Financial Statements of the Company as of December 31, 1993,
incorporated herein by reference.
 
  General corporate expenses, reported on a segment basis, increased slightly
in 1993 compared to 1992, but were $817 million lower in 1992 compared to 1991,
reflecting the charge of $824 million for uninsured asbestos personal injury
claims. Please see Notes 1 and 19 to the Consolidated Financial Statements of
the Company as of December 31, 1993, incorporated herein by reference.
 
  Effective January 1, 1993, the Company adopted the new accounting standard
for income taxes (SFAS No. 109). The standard changes the criteria for
measuring the provision for income taxes and recognizing deferred tax assets
and liabilities. As noted above, the cumulative effect of adopting SFAS No. 109
increased earnings by $26 million (or $.53 per share). As discussed in Note 4
to the Consolidated Financial Statements of the Company as of December 31,
1993, incorporated herein by reference, the Company's net deferred tax assets
arise primarily as a result of the temporary differences associated with its
provisions for asbestos litigation claims and other postretirement benefits.
Management fully expects to realize its net deferred tax assets through income
from future operations.

LIQUIDITY, CAPITAL RESOURCES AND OTHER RELATED MATTERS
 
 Six Months Ended June 30, 1994
 
  Cash flow from operations was a negative $6 million for the second quarter,
compared to $12 million for the second quarter of 1993. The decrease in cash
flow is primarily due to a $24 million increase in payments (net of insurance
proceeds) for uninsured asbestos litigation claims and increased working
capital needs compared to the prior year's quarter. Net inventories increased
from $221 million at year-end 1993 to $259 million at the end of the second
quarter primarily due to anticipated seasonal demand for building products and
the purchase of inventories from the above mentioned acquisitions. Total
receivables at June 30, 1994 were $447 million, $123 million higher than at
year-end 1993 because of acquisitions and high sales levels for building
products worldwide and composites in North America in the second quarter.
 
  At June 30, 1994, the Company's working capital was a negative $15 million
and its current ratio was .99, compared to a negative $49 million and .94,
respectively, at December 31, 1993.
 
  Total borrowings at June 30, 1994 were $332 million higher than at year-end
1993, primarily due to the Pilkington acquisition, capital expenditures, and
asbestos payments (net of tax). In connection with the Pilkington acquisition,
the Company established, effective June 1, 1994, a $110 million 364-day credit
facility with a syndicate of banks led by the Bank of New York. In addition,
effective July 18, 1994, the Company amended its long-term U.S. loan facility,
led by Credit Suisse, to increase the available lines of credit by $100
million. In July 1994, the Company established a Canadian credit facility with
a syndicate of banks, led by Credit Suisse Canada, serving as agent, replacing
the previous facility which expired in July 1994. The new facility has a
commitment of 95 million Canadian dollars (69 million U.S. dollars) and expires
in October 1997. As of July 31, 1994, the Company had unused lines of credit of
$186 million available under long-term bank loan facilities and an additional
$96 million under short-term facilities, compared to $376 million and $64
million, respectively, at year-end 1993. The decline in unused available lines
of credit reflects the Company's higher borrowings and an increase of
outstanding letters of credit, supporting appeals from asbestos trials, counted
against the Company's long-term U.S. loan facility.
 
  Capital spending for property, plant and equipment, excluding acquisitions,
was $64 million during the second quarter. At the end of the quarter, approved
capital projects, including furnace rebuilds, were $125 million. The Company
expects that funding for these expenditures will be from the Company's
operations and external sources as required.
 
  Payments for asbestos litigation claims during the second quarter of 1994,
including $15 million in defense costs, were $39 million. Proceeds from
insurance were $14 million. In the second quarter of 1994, the Company received
about 5,300 new asbestos personal injury cases and closed approximately 5,900
cases. Over the next twelve months, the Company's payments for asbestos
litigation claims, including defense costs, are expected to be approximately
$300 million and proceeds from insurance of $175 million are expected to be
available to cover these costs. Please see Note 12 to the Consolidated
Financial Statements of the Company as of June 30, 1994, incorporated herein by
reference.
 
  The Company expects funds generated from operations, together with funds
available under long and short term bank loan facilities, to be sufficient to
satisfy its debt service obligations under its existing indebtedness, as well
as its contingent liabilities for uninsured asbestos personal injury claims.
 
 Fiscal Years 1993, 1992 and 1991
 
  Cash flow from operations was $253 million for 1993, compared to $192 million
for 1992 and $253 million for 1991. The increase in cash flow from operations,
compared to 1992, was primarily due to an
 
                                       12
<PAGE>
 
increase in trade payables. Receivables were $324 million at December 31, 1993,
compared to $309 million at the end of 1992 and $308 million at the end of
1991. Net inventories were $221 million at year-end 1993 compared to $233
million and $219 million at year-end 1992 and 1991, respectively. Inventories
at December 31, 1993, as a percentage of the fourth quarter's annualized sales,
were 7%, a one percentage point decrease from the end of 1992 and 1991.
 
  During 1993, the Company adopted Financial Accounting Standards Board
Interpretation No. 39 (FIN 39). FIN 39 requires the Company to present
separately in the balance sheet its estimated contingent liabilities and
related insurance assets. Accordingly, the incorporated consolidated balance
sheet as of December 31, 1992 and consolidated statement of cash flows for the
years ended December 31, 1992 and 1991 have been restated to conform to the
1993 presentation. Please see Note 19 to the Consolidated Financial Statements
of the Company as of December 31, 1993 and the related Summary of Significant
Accounting Policies, both incorporated herein by reference.
 
  At year-end 1993, the Company's working capital was a negative $49 million
and its current ratio decreased to .94, compared to working capital of $123
million and a current ratio of 1.2 at year-end 1992, and $171 million and 1.2,
respectively, at year-end 1991. The 1992 and 1991 working capital and current
ratios have been restated to conform to FIN 39. The decrease in 1993 was
primarily due to the increase in trade payables and the timing of receipt of
the insurance proceeds for asbestos litigation claims. Please see Note 19 to
the Consolidated Financial Statements of the Company as of December 31, 1993
and the related Summary of Significant Accounting Policies, both incorporated
herein by reference.
 
  The Company's total borrowings at December 31, 1993, were $1.0 billion,
compared to $1.1 billion at December 31, 1992, and $1.2 billion at December 31,
1991. In the fourth quarter of 1993, the Company established a $375 million
credit facility with a syndicate of banks, replacing the previous facility due
to expire in July 1994. The facility agreement is for a four year term,
effective November 2, 1993. In 1992, the Company issued $300 million in 10 and
20 year debentures at an average interest rate of 9 1/8%. The majority of the
proceeds were used to redeem $240 million in higher cost debentures. Please see
Note 2 to the Consolidated Financial Statements of the Company as of December
31, 1993, incorporated herein by reference.
 
  General corporate identifiable assets have been restated in 1992 and 1991 to
conform to the 1993 reporting format with the adoption of FIN 39. General
corporate identifiable assets for 1993 and 1992 decreased compared to 1991,
primarily due to the consumption of the insurance for asbestos litigation
claims asset. Please see Notes 1 and 19 to the Consolidated Financial
Statements of the Company as of December 31, 1993 and the related Summary of
Significant Accounting Policies, both incorporated herein by reference.
 
  Capital spending for property, plant and equipment was $164 million in 1993,
compared to $130 million in 1992 and $96 million in 1991.
 
  Payments for asbestos litigation claims in 1993, including defense costs,
were $283 million as 22,300 claims were resolved. Proceeds from insurance were
$224 million. Please see Note 19 to the Consolidated Financial Statements of
the Company as of December 31, 1993, incorporated herein by reference.
 
GENERAL MATTERS
 
  The Company has been deemed by the Environmental Protection Agency (EPA) to
be a potentially responsible party (PRP) with respect to certain sites under
the Comprehensive Environmental Response, Compensation and Liability Act
(Superfund). The Company has also been deemed a PRP under similar state or
local laws. In other instances, other PRPs have brought suits or claims against
the Company as a PRP for contribution under such federal, state or local laws.
During the second quarter of 1994, the Company was designated as a PRP in such
federal, state, local or private proceedings for no additional sites. At June
30, 1994, a total of 38 such PRP designations remained unresolved by the
Company, some of which designations the Company believes to be erroneous. The
Company is also involved with environmental investigation or
 
                                       13
<PAGE>
 
remediation at a number of other sites at which it has not been designated a
PRP. The Company has established reserves for its Superfund (and similar state,
local and private action) contingent liabilities which are reflected in the
financial statements. The Company believes these reserves are adequate to cover
these liabilities and are not material to the financial position or results of
operations of the Company. In addition, based upon information presently
available to the Company, and without regard to the application of insurance,
the Company believes that, considered in the aggregate, the additional costs
associated with such contingent liabilities, including any related litigation
costs, will not have a materially adverse effect on the Company's financial
position or results of operations.
 
  The 1990 Clean Air Act Amendments (Act) provide that the EPA will issue
regulations on a number of air pollutants over a period of years. Until these
regulations are developed, the Company cannot determine the extent the Act will
affect it. The Company anticipates that its sources to be regulated will
include glass fiber manufacturing, resin manufacturing and asphalt processing
activities. The Company currently expects glass fiber manufacturing to be
regulated by 1997. Based on information now known to the Company, including the
nature and limited number of regulated materials it emits, the Company does not
expect the Act to have a material adverse effect on the Company's results of
operations, financial condition, or long-term liquidity.
 
                              ASBESTOS LITIGATION
 
  The following is a discussion of the status of the asbestos litigation; see
also "Management's Discussion and Analysis of Financial Condition and Results
of Operations--Liquidity, Capital Resources and Other Related Matters."
 
ASBESTOS LIABILITIES
 
  The Company is a co-defendant with other former manufacturers, distributors
and installers of products containing asbestos and with miners and suppliers of
asbestos fibers (collectively, the "Producers") in personal injury and property
damage litigation. The personal injury claimants generally allege injuries to
their health caused by inhalation of asbestos fibers from the Company's
products. Most of the claimants seek punitive damages as well as compensatory
damages. The property damage claims generally allege property damage to school,
public and commercial buildings resulting from the presence of products
containing asbestos. Virtually all of the asbestos-related lawsuits against the
Company arise out of its manufacture, distribution, sale or installation of an
asbestos-containing calcium silicate, high temperature insulation product, the
manufacture of which was discontinued in 1972.
 
 Status
 
  As of June 30, 1994, approximately 98,300 asbestos personal injury claims
were pending against the Company, 5,300 of which were received in the second
quarter of 1994. The Company received approximately 31,700 such claims in 1993,
and 26,600 in 1992.
 
  Through June 30, 1994, the Company had resolved (by settlement or otherwise)
approximately 131,100 asbestos personal injury claims. During 1992, 1993 and
the first two quarters of 1994, the Company resolved approximately 58,500 such
claims and incurred total indemnity payments of $560 million (an average of
about $10,000 per case). The Company's indemnity payments have varied
considerably over time and from case to case, and are affected by a multitude
of factors. These include the type and severity of the disease sustained by the
claimant (i.e., mesothelioma, lung cancer, other types of cancer, asbestosis or
pleural changes); the occupation of the claimant; the extent of the claimant's
exposure to asbestos-containing products manufactured, sold or installed by the
Company; the extent of the claimant's exposure to asbestos-containing products
manufactured, sold or installed by other Producers; the number and financial
resources of other Producer defendants; the jurisdiction of suit; the presence
or absence of other possible causes of the claimant's illness; the availability
or not of legal defenses such as the statute of limitations or state of the
art; whether
 
                                       14
<PAGE>
 
the claim was resolved on an individual basis or as part of a group settlement;
and whether the claim proceeded to an adverse verdict or judgment.
 
  Certain of the Company's principal co-defendants, the 20 members of the
Center for Claims Resolution, have entered into a proposed "global" settlement
which would require future claimants to satisfy certain medical criteria
indicative of significant asbestos-related impairment as a pre-condition to
their eligibility for settlement payments. The Company is using similar
criteria in the implementation of its own settlement and litigation strategy
and is also seeking to require more careful proof than in the past that
claimants had significant exposure to the Company's asbestos-containing product
or operations. The Company believes that this strategy will reduce the overall
cost of asbestos personal injury claims in the long run by channeling indemnity
payments to claimants who can establish significant asbestos-related impairment
and exposure to the Company's asbestos-containing product or operations and by
substantially reducing indemnity payments to individuals who are unimpaired or
who did not have significant such exposure. The Company's strategy has resulted
in an increased level of trial activity and an increase in the number and
amount of compensatory and punitive damage verdicts and judgments against the
Company. This strategy may have the effect of increasing average per-case
indemnity costs for claims resolved with payment, while also increasing the
number of claims dismissed without payment.
 
 Insurance
 
  As of June 30, 1994, the Company had approximately $401 million in
unexhausted products hazard coverage (net of deductibles and self-insured
retentions and excluding coverage issued by insolvent carriers) under its
liability insurance policies applicable to asbestos personal injury claims. Of
this amount, $144 million will not be available until the years 1996 through
2000 under an agreement with the carrier confirming such insurance. An
additional $48 million (out of the $401 million coverage) is presently the
subject of coverage litigation or alternate dispute resolution procedures. All
of the Company's liability insurance policies cover indemnity payments and
defense fees and expenses subject to applicable policy limits.
 
  In addition, the Company has substantial unexhausted non-products coverage
under such liability insurance policies; an as yet undetermined amount of such
non-products coverage is expected to be available for payment of asbestos
personal injury claims and associated defense fees and expenses. The Company
has commenced arbitration with its primary level insurance carrier seeking to
confirm the availability of certain of its non-products coverage for payment of
certain asbestos personal injury liabilities, involving the activities of the
Company's former insulation contracting business. The Company is seeking prompt
rulings on the issues presented, and the arbitration agreement contemplates a
schedule that would result in resolution (subject to appeal) in 1994. For
purposes of calculating the amount of insurance applicable to asbestos
liabilities, the Company has estimated its recoveries in respect of non-
products coverage for claims received through 1999 at approximately $310
million, which represents the Company's best estimate of such recoveries for
such claims. The Company cautions, however, that this coverage is unconfirmed
and that the actual amounts recovered by the Company could, depending upon the
outcome of the arbitration, be much higher or much lower.

 Reserve
 
  The Company's estimated total liabilities in respect of indemnity and defense
costs associated with pending and unasserted asbestos personal injury claims
that may be received through the year 1999 (the "Liabilities"), and its
estimated insurance recoveries in respect of such claims (the "Insurance"), are
reported separately as follows:

  Case filing rates were at historically high levels in 1992 and 1993
(approximately 26,600 new claims in 1992 and approximately 31,700 claims in
1993) and an additional 10,700 new claims were received during the first two
quarters of 1994. Many of these new claims appear to be the product of mass
screening programs and not to involve significant asbestos-related impairment.
The large number of recent filings and the uncertain value of these claims have
added to the uncertainties involved in estimating the Company's asbestos
Liabilities.
 
  The Company cautions that such factors as the number of future asbestos
personal injury claims received by it, the rate of receipt of such claims, and
the indemnity and defense costs associated with asbestos personal injury
claims, as well as the prospects for confirming additional, applicable
insurance coverage beyond the $401 million referenced above, are influenced by
numerous variables that are difficult to predict, and that estimates, such as
the Company's, which attempt to take account of such variables, are subject to
considerable uncertainty. Depending upon the outcome of the various
uncertainties described above, particularly as they relate to unimpaired
claims, it may be necessary at some point in the future for the Company to make
additional provision for the uninsured costs of asbestos personal injury claims
received through the year 1999 (although no such amounts are reasonably
estimable at this time). The Company remains confident that its estimate of
Liabilities and Insurance will be sufficient to provide for the costs of all
such claims that involve malignancies or significant asbestos-related
functional impairment. The Company has reviewed and will continue to review the
adequacy of its estimate of Liabilities and Insurance on a periodic basis and
make such adjustments as may be appropriate.
 
  The Company cannot estimate and is not providing for the cost of unasserted
claims which may be received by the Company after the year 1999 because
management is unable to predict the number of claims to be received after 1999,
the severity of disease which may be involved and other factors which would
affect the cost of such claims.
 
 Cash Expenditures
 
  The Company's anticipated cash expenditures for uninsured asbestos-related
costs of claims received through 1999 are expected to approximate $808 million,
the Company's Liabilities, net of Insurance. Cash payments will vary annually
depending upon a number of factors, including the pace of the Company's
resolution of claims and the timing of payment of its Insurance.

 Management Opinion
 
  Although any opinion is necessarily judgmental and must be based on
information now known to the Company, in the opinion of management, the
additional uninsured and unreserved costs which may arise out of pending
personal injury and property damage asbestos claims and additional similar
asbestos claims filed in the future will not have a materially adverse effect
on the Company's financial position. While such additional uninsured and
unreserved costs incurred in and after the year 2000 may be substantial over
time, management believes that any such additional costs will not impair the
ability of the Company to meet its obligations, to reinvest in its businesses
or to take advantage of attractive opportunities for growth.
 
NON-ASBESTOS LIABILITIES
 
  In October 1991, the Company and certain of its officers and directors were
named as defendants in a lawsuit captioned Gaetana Lavalle v. Owens-Corning
Fiberglas Corporation, et al. in the United States District Court for the
Northern District of Ohio. Lavalle purports to be a securities class action on
behalf of all purchasers of the Company's common stock during the period
November 1, 1988 through October 18, 1991. The complaint alleges that the
Company's disclosures during the alleged class period contained material
misstatements and omissions concerning its contingent liabilities for asbestos
claims. The complaint seeks an unspecified amount of damages (including
punitive damages) on the theory that such alleged misstatements and omissions
artificially inflated the price of the Company's stock. Various other lawsuits
and claims arising in the normal course of business are pending against the
Company, some of which allege substantial damages. Management believes that the
outcome of these lawsuits and claims will not have a materially adverse effect
on the Company's financial position or results of operations.
 
                          DESCRIPTION OF CAPITAL STOCK
 
  The Company's Certificate of Incorporation, as amended (the "Charter"),
currently authorizes the issuance of two classes of stock: (i) 100 million
shares of Common Stock, par value $0.10 per share, of which 43,662,236 shares
were issued and outstanding as of July 31, 1994 and (ii) 8 million shares of
Preferred Stock, without par value, of which no shares were issued and
outstanding on such date.
 
  The following descriptions of the classes of the Company's capital stock are
summaries, do not purport to be complete, and are subject, in all respects, to
the applicable provisions of the General Corporation Law of Delaware, the
Charter, the Certificate of Designation of Series A Participating Preferred
Stock (and the Certificate of Increase of Designation of Series A Participating
Preferred Stock (the "Certificate of Increase")) and the Rights Agreement (as
hereinafter defined) which, in the case of the Charter, the Certificate of
Designation (and the Certificate of Increase) and the Rights Agreement, are
included as Exhibits to the Registration Statement of which this Prospectus
forms a part.
 
COMMON STOCK
 
  Each holder of Common Stock is entitled to one vote for every share standing
in his or her name on the books of the Company. The Common Stock does not have
cumulative voting rights for the election of directors, which means that
holders of more than 50% of the shares voting for the election of directors can
elect 100% of the directors if they choose to do so, and, in such event, the
holders of the remaining shares voting for the election of directors will not
be able to elect any person or persons to the Board of Directors.
 
  Subject to the limitations contained in the Company's debt instruments and
after provision for the payment of dividends on any series of Preferred Stock
which might be issued and which has a preference with respect to the payment of
dividends, holders of Common Stock are entitled to receive such dividends as
may be declared by the Board. See "Price Range of Common Stock and Dividends"
above.
 
  The Common Stock has no conversion rights and is not redeemable. No holder of
Common Stock has any preemptive right to subscribe for any stock or other
securities of the Company which may be issued.
 
                                       17
<PAGE>
 
  In the event of dissolution, liquidation or winding up of the Company, or
upon any distribution of its assets, the holders of Common Stock are entitled
to receive pro rata all of the assets available for distribution to
stockholders, subject to any preferential right which may be accorded to any
series of Preferred Stock which might be issued.
 
  The Company's Common Stock is listed on the NYSE and the TSE. The outstanding
shares of Common Stock are validly issued, fully paid and non-assessable.
 
PREFERRED STOCK
 
  The Board of Directors of the Company has the authority, without further
action by stockholders, to determine the principal rights, preferences and
privileges of any unissued Preferred Stock. Provisions may be included in the
shares of Preferred Stock, such as extraordinary voting, dividend, redemption
or conversion rights, which could discourage an unsolicited tender offer or
takeover proposal.
 
  Out of the authorized Preferred Stock, the Company has designated 750,000
shares of Series A Participating Preferred Stock ("Series A Preferred Stock"),
the terms of which are summarized below under "Series A Preferred Stock." Each
outstanding share of Common Stock includes a right to purchase one one-
hundredth of a share of Series A Preferred Stock ("Preferred Share Purchase
Rights"), which Rights are registered on the New York Stock Exchange and the
terms of which are summarized below under "Preferred Share Purchase Rights."
 
SERIES A PREFERRED STOCK
 
 Dividends
 
  Holders of shares of Series A Preferred Stock are entitled to receive, when,
as and if declared by the Board of Directors out of funds legally available for
the purpose, dividends, payable in cash quarterly in arrears on January 1,
April 1, July 1 and October 1 of each year (each a "Quarterly Dividend Payment
Date"), at an annual rate per share of the greater of (i) $10.00 or (ii) 100
times the aggregate per share amount of all cash and non-cash dividends or
other distributions (other than dividends payable in Common Stock or
subdivisions of outstanding shares of Common Stock) declared on the Common
Stock since the last Quarterly Dividend Payment Date. Accrued but unpaid
dividends accumulate but do not bear interest.
 
  The Series A Preferred Stock will be junior as to dividends to any series or
class of Preferred Stock (or any similar stock) that ranks senior as to
dividends to the Series A Preferred Stock. The Series A Preferred Stock has
priority as to dividends over the Common Stock and any other series or class of
the Company's stock thereafter issued that ranks junior as to dividends to the
Series A Preferred Stock. If dividends or distributions payable on the Series A
Preferred Stock are in arrears, the Company (i) may not declare or pay
dividends or other distributions on the Common Stock (or any other stock of the
Company that ranks junior to the Series A Preferred Stock) and (ii) is
restricted in its declaration and payment of dividends or other distributions
on any stock of the Company that ranks on a parity with the Series A Preferred
Stock except for dividends paid ratably in accordance with the respective
preferential amounts payable on the Series A Preferred Stock and all such
parity stock.
 
 Liquidation Rights
 
  In the case of the voluntary or involuntary liquidation, dissolution or
winding-up of the Company, holders of shares of Series A Preferred Stock are
entitled to receive the liquidation preference of the higher of (i) $100.00 per
share, plus an amount equal to the accrued and unpaid dividends to the payment
date, or (ii) 100 times the aggregate per share amount to be distributed to
holders of shares of Common Stock, before any payment or distribution is made
to the holders of shares of Common Stock (or any other stock of the Company
that ranks junior to the Series A Preferred Stock). The holders of shares of
Series A Preferred Stock and of any other stock of the Company that ranks on a
parity with the Series A Preferred Stock are
 
                                       18
<PAGE>
 
entitled to share ratably, in accordance with the respective preferential
amounts payable on such stock, in any distribution that is not sufficient to
pay in full the aggregate of the amounts payable thereon.
 
 Consolidation and Merger Rights
 
  In case the Company enters into any consolidation, merger, combination or
other transaction in which the shares of Common Stock are changed into or
exchanged for other stock or securities, cash and/or any other property, each
share of Series A Preferred Stock at the same time will be similarly changed
into or exchanged for an amount per share equal to 100 times the aggregate
amount of stock or securities, cash and/or any other property into which or for
which each share of Common Stock is changed or exchanged.
 
 Limitation on Share Repurchase
 
  If dividends or distributions payable on the Series A Preferred Stock are in
arrears, the Company may not redeem, purchase or otherwise acquire for
consideration (i) any stock of the Company that ranks on a parity with the
Series A Preferred Stock, except in exchange for shares of any stock of the
Company ranking junior to the Series A Preferred Stock or (ii) any shares of
Series A Preferred Stock or any stock of the Company that ranks on a parity
with the Series A Preferred Stock, except through a purchase offer made in
writing or by publication to all holders of such shares on terms that the Board
of Directors determines will result in fair and equitable treatment among the
respective series or classes of shares.
 
 Voting Rights
 
  Each share of Series A Preferred Stock entitles the holder thereof to 100
votes on all matters submitted to a vote of the Company's stockholders, and the
holders of shares of Series A Preferred Stock and the holders of shares of
Common Stock and any other capital stock of the Company having general voting
rights will vote together as one class on all matters submitted to a vote of
the Company's stockholders.
 
  If, at the time of any annual stockholders' meeting for the election of
directors, the equivalent of at least six quarterly dividends payable on any
shares of Series A Preferred Stock are in default, the number of members of the
Company's Board of Directors will be increased by two, and the holders of the
Series A Preferred Stock, voting separately as a class, will be entitled at
such meeting (and each subsequent annual stockholders' meeting) to elect such
two additional directors. Such voting rights will terminate when all such
dividends in arrears have been paid or declared and set apart for payment. Upon
the termination of such voting rights, the terms of office of all directors so
elected will terminate immediately and the number of members of the Company's
Board of Directors will be reduced by two.
 
 Other Features
 
  The shares of Series A Preferred Stock are not redeemable. Unless otherwise
provided in the Company's Restated Certificate of Incorporation or the
designation of a subsequent series of Preferred Stock, the Series A Preferred
Stock will rank junior to all of the Company's other series of Preferred Stock
as to the payment of dividends and the distribution of assets on liquidation,
dissolution or winding-up, and senior to the Company's Common Stock. Series A
Preferred Stock may be issued in fractions of a share (in one one-hundredths
(1/100) of a share and integral multiples thereof).
 
PREFERRED SHARE PURCHASE RIGHTS
 
  Under a Rights Agreement, dated as of December 18, 1986 (the "Rights
Agreement"), between the Company and Chemical Bank (as successor by merger to
Manufacturers Hanover Trust Company), as Rights Agent, each outstanding share
of Common Stock is coupled with a Preferred Share Purchase Right. Each Right
entitles the holder to buy from the Company one one-hundredth of a share of
Series A Preferred Stock at a price of $50. The Board of Directors has
designated 750,000 shares of the Company's authorized preferred stock as Series
A Preferred Stock. There are currently no shares of Preferred Stock
outstanding.
 
                                       19
<PAGE>
 
  Rights become exercisable and detach from the Common Stock ten days after a
person or group acquires, or announces a tender offer for, 20% or more of the
Company's outstanding shares of Common Stock. The rights expire on December 30,
1996, unless redeemed earlier by the Company. The rights are redeemable by the
Company at one cent each at any time prior to ten days following public
announcement or notice to the Company that an acquiring person or group has
purchased 20% or more of the Company's outstanding Common Stock. If the Company
is acquired in a merger or other business combination at any time after the
rights become exercisable, each right would entitle its holder to buy shares of
the acquiring or surviving company having a market value of twice the exercise
price of the right. Until the Preferred Share Purchase Rights detach from the
Common Stock (or the earlier termination or redemption of the Preferred Share
Purchase Rights), an additional Preferred Share Purchase Right will be issued
with every share of newly issued Common Stock.
 
DELAWARE LAW AND CERTAIN CHARTER PROVISIONS
 
  The Company is subject to the provisions of Section 203 of the General
Corporation Law of Delaware. In general, this statute prohibits a publicly held
Delaware corporation from engaging in a "business combination" with an
"interested stockholder" for a period of three years after the date of the
transaction in which the person becomes an interested stockholder, unless the
business combination is approved in a prescribed manner. An "interested
stockholder" is a person who, together with affiliates and associates, owns (or
within the prior three years did own) 15% or more of the corporation's voting
stock.
 
  In addition to Section 203 of the General Corporation Law of Delaware and the
Preferred Share Purchase Rights, the Charter contains several provisions that
may discourage certain transactions involving an actual or threatened change of
control of the Company.
 
  For example, the Charter requires that certain business combinations and
other combinations involving the Company and a holder of 10% or more of its
voting securities be approved by at least 66% of all shares having voting
rights.
 
  The foregoing provisions of the General Corporation Law of Delaware and the
Charter are intended to encourage persons seeking to acquire control of the
Company to consult first with the Board of Directors to permit negotiation of
the terms of any proposed business combination or offer. They may, however,
also have the effect of discouraging a third party from attempting to acquire
control of the Company. In addition, since these provisions are designed to
discourage accumulations of large blocks of stock by third parties who wish to
gain control of the Company, such provisions may reduce the temporary market
price fluctuations caused by such accumulations.
 
TRANSFER AGENT AND REGISTRAR
 
  The primary Transfer Agent and Registrar for the Common Stock is Chemical
Bank, located in New York, New York.
 
                              PLAN OF DISTRIBUTION
 
  The distribution of the shares offered hereby by the Selling Stockholders may
be effected promptly after the effective date of the Registration Statement of

prevailing at the time of sale in accordance with the terms of the Common Stock
Registration Rights Agreement between the Company and the Selling Stockholders.
Such transactions may be effected on a stock exchange or the over-the-counter
market. The Selling Stockholders may effect such transactions by selling shares
to or through broker-dealers, including Goldman, Sachs & Co., and such broker-
dealers may receive compensation in the form of discounts or commissions from
the Selling Stockholders and commissions from purchasers of shares for whom
they may act as agent. Such discounts or commissions will not exceed
 
                                       20
<PAGE>
 
those customary for the types of transactions involved. The Company has agreed
to indemnify the Selling Stockholders and certain control and other related
persons in certain circumstances against certain liabilities, including
liabilities under the Securities Act. The Selling Stockholders have agreed to
indemnify the Company and certain control and related persons against certain
liabilities, including liabilities under the Securities Act, but only in
limited circumstances arising out of such Selling Stockholders having furnished
incorrect written information to the Company for use in this Registration
Statement. The Company and the Selling Stockholders may also indemnify any
broker-dealer, including Goldman, Sachs & Co., that participates in the
distribution of the shares offered hereby from certain liabilities, including
liabilities under the Securities Act.
 
 
  The Company is directly or indirectly bearing all costs relating to the
registration of the shares offered hereby, including any underwriting discounts
or commissions directly attributable to the sale of the shares offered hereby
by or on behalf of the Selling Stockholders. Any broker-dealer, including
Goldman, Sachs & Co., that participates in the distribution of the shares
offered hereby may be deemed to be an "underwriter" within the meaning of the
Securities Act, and any commissions and discounts received by such broker-
dealer and any profit on the resale of the shares offered hereby by such
broker-dealer might be deemed to be underwriting discounts and commissions
under the Securities Act.
 
                               VALIDITY OF SHARES
 
  The validity of the shares of Common Stock offered hereby and of the related

51,000 options to buy shares of Common Stock, 34,001 of which are currently

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  A. Reference is made to Section 102(b)(7) of the General Corporation Law of
the State of Delaware as to the limitation of personal liability of directors
and officers and to Section 145 of the General Corporation Law of the State of
Delaware as to indemnification by the Company of its directors and officers.
 
  B. Article FOURTEENTH of the Company's Certificate of Incorporation, as
amended, provides as follows with respect to the indemnification of the
Company's directors and officers and the limitation of personal liability of
its directors and officers:
 
    FOURTEENTH: The corporation shall indemnify to the full extent authorized
  or permitted by law any person made, or threatened to be made, a party to
  any action or proceeding (whether civil or criminal or otherwise) by reason
  of the fact that he, his testator or intestate, is or was a director or
  officer of the corporation or by reason of the fact that such director or
  officer, at the request of the corporation, is or was serving any other
  corporation, partnership, joint venture, trust, employee benefit plan or
  other enterprise, in any capacity. Nothing contained herein shall affect
  any rights to indemnification to which employees other than directors and
  officers may be entitled by law. No director of the corporation shall be
  personally liable to the corporation or its stockholders for monetary
  damages for any breach of fiduciary duty by such a director as a director.
  Notwithstanding the foregoing sentence, a director shall be liable to the
  extent provided by applicable law (i) for any breach of the director's duty
  of loyalty to the corporation or its stockholders, (ii) for acts or
  omissions not in good faith or which involve intentional misconduct or a
  knowing violation of law, (iii) pursuant to Section 174 of the Delaware
  General Corporation Law, or (iv) for any transaction from which such
  director derived an improper personal benefit. No amendment to or repeal of
  this Article FOURTEENTH shall apply to or have any effect on the liability
  or alleged liability of any director of the corporation for or with respect
  to any acts or omissions of such director occurring prior to such
  amendment.
 
  C. Article IX of the Company's By-Laws provides as follows with respect to
the indemnification of the Company's directors and officers:
 
                                   ARTICLE IX
 
                   INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  The Corporation shall, to the fullest extent permitted by applicable law from
time to time in effect (but, in the case of any amendment of such law, only to
the extent that such amendment permits the Corporation to provide broader
indemnification rights than such law permitted the Corporation to provide prior
to such
 
                                      II-1
<PAGE>
 
amendment), indemnify any and all persons who may serve or who have served at
any time as directors or officers of the Corporation, or who at the request of
the Corporation may serve or at any time have served as directors, officers,
employees or agents of another corporation (including subsidiaries of the
Corporation) or of any partnership, joint venture, trust or other enterprise,
and any directors or officers of the Corporation who at the request of the
Corporation may serve or at any time have served as agents or fiduciaries of an
employee benefit plan of the Corporation or any of its subsidiaries, from and
against any and all of the expenses, liabilities or other matters referred to
in or covered by law whether the basis of such proceeding is alleged action in
an official capacity as a director, officer, employee or agent or in any other
capacity while serving as a director, officer, employee or agent. The
Corporation may also indemnify any and all other persons whom it shall have
power to indemnify under any applicable law from time to time in effect to the
extent permitted by such law. The indemnification provided by this Article IX
shall not be deemed exclusive of any other rights to which any person may be
entitled under any provision of the Certificate of Incorporation, other By-Law,
agreement, vote of stockholders or disinterested directors, or otherwise, both
as to action in an official capacity and as to action in another capacity while
holding such office, and shall be contract rights and 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.
 
  If a claim under this Article IX is not paid in full by the Corporation
within sixty days after a written claim has been received by the Corporation,
except in the case of a claim for an advancement of expenses, in which case the
applicable period shall be twenty days, the director or officer may at any time
thereafter bring suit against the Corporation to recover the unpaid amount of
the claim. If successful in whole or in part in any such suit, or in a suit
brought by the Corporation to recover an advancement of expenses pursuant to
the terms of an undertaking, the director or officer shall be entitled to be
paid also the expense of prosecuting or defending such suit. In (i) any suit
brought by the director or officer to enforce a right to indemnification
hereunder (but not in a suit brought by the director or officer to enforce a
right to an advancement of expenses) it shall be a defense that, and (ii) any
suit by the Corporation to recover an advancement of expenses pursuant to the
terms of an undertaking, the Corporation shall be entitled to recover such
expenses upon a final adjudication that, the director or officer has not met
any applicable standard for indemnification set forth in the Delaware General
Corporation Law. Neither the failure of the Corporation (including its Board of
Directors, independent legal counsel, or its stockholders) to have made a
determination prior to the commencement of such suit that indemnification of
the director or officer is proper in the circumstances because the director or
officer has met the applicable standard of conduct set forth in the Delaware
General Corporation Law, nor an actual determination by the Corporation
(including its Board, independent legal counsel, or its stockholders) that the
director or officer has not met such applicable standard of conduct, shall
create a presumption that the director or officer has not met the applicable
standard of conduct or, in the case of such a suit brought by the director or
officer, be a defense to such suit. In any suit brought by the director or
officer to enforce a right to indemnification or to an advancement of expenses
hereunder, or by the Corporation to recover an advancement of expenses pursuant
to the terms of an undertaking, the burden of proving that the director or
officer is not entitled to be indemnified, or to such advancement of expenses,
under this Article IX or otherwise shall be on the Corporation.
 
  The indemnification provided in this Article IX shall inure to each person
referred to herein, whether or not the person is serving in any of the
enumerated capacities at the time such expenses (including attorneys' fees),
judgments, fines or amounts paid in settlement are imposed or incurred, and
whether or not the claim asserted against him is based on matters which
antedate the adoption of this Article IX. None of the provisions of this
Article IX shall be construed as a limitation upon the right of the Corporation
to exercise its general power to enter into a contract or understanding of
indemnity with a director, officer, employee, agent or any other person in any
proper case not provided for herein. Each person who shall act or have acted as
a director or officer of the Corporation shall be deemed to be doing so in
reliance upon such right of indemnification.
 
  For purposes of this Article IX, the term "Corporation" shall include
constituent corporations referred to in subsection (h) of Section 145 of the
General Corporation Law of the State of Delaware (or any similar provision of
applicable law at the time in effect).
 
                                      II-2
<PAGE>
 
  D. The Company has entered into an Indemnity Agreement with each member of
the Company's Board of Directors. Each Indemnity Agreement provides, among
other things, that in the event the director was, is or becomes a party,
witness or other participant in a Claim (as defined in the Indemnity Agreement)
by reason of (or arising in part out of) an Indemnifiable Event (as defined in
the Indemnity Agreement), the Company is required to indemnify the director to
the fullest extent authorized by the Company's By-Laws as in effect on the date
of the Indemnification Agreement notwithstanding any subsequent amendment,
repeal or modification of such By-Laws, against any and all expenses,
judgments, fines, penalties and amounts paid in settlement of such Claim. The
Indemnity Agreement requires that the Company advance to the director all
expenses relating to Claims and contains an undertaking by the director to
reimburse the Company for any such advances that are subsequently determined in
a final judicial determination to have been impermissible under applicable law.
 
  E. The directors and officers of the Company are covered by insurance
policies, maintained by the Company at its expense, insuring the directors and
officers against certain liabilities which might be incurred by them in such
capacities, including liabilities arising under the Securities Act of 1933.

ITEM 17. UNDERTAKINGS.
 
  (a) Filings Incorporating Subsequent Exchange Act Documents by Reference.
 
  The undersigned registrant hereby undertakes 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 15(d) of the Securities
Exchange Act 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 deemed to be the initial bona fide offering thereof.
 
  (b) Policy Regarding Indemnification.
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the
 
                                      II-3
<PAGE>
 
Registrant 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
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant 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 Registrant 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 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.
 
  (c) Rule 430A Offering.
 
  The undersigned hereby undertakes that:
 
  (1) For purposes of determining any liability under the Securities Act of
1933, the information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the Corporation pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this registration
statement as of the time it was declared effective.
 
  (2) For the purpose of determining any liability under the Securities Act of
1933, each post-effective amendment that contains a form of prospectus 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.

  appropriate form under the Securities Act, which form (i) shall be selected
  by the Company and (ii) shall comply as to form in all material respects
  with the requirements of the applicable form and include all financial
  statements required by the SEC to be filed therewith, and the Company shall
  use all reasonable efforts to cause such Registration Statement to become
  effective and remain effective in accordance with Section 2 hereof.
 
    (b) prepare and file with the SEC such amendments and post-effective
  amendments to each Registration Statement as may be necessary to keep such
  Registration Statement effective as provided in Section 2, cause each
  related Prospectus to be supplemented by any required prospectus supplement
  and, as so supplemented, to be filed pursuant to Rule 424 under the
  Securities Act;
 
    (c) furnish to each Holder of Registrable Securities, without charge, as

  any amendment or supplement thereto and such other documents as such Holder
  may reasonably request, in order to facilitate the public sale or other
  disposition of the Registrable Securities;
 
    (d) use all reasonable efforts to register or qualify the Registrable
  Securities under all applicable state securities or Blue Sky laws of such
  jurisdictions as any Holder thereof covered by a Registration Statement
  shall reasonably request in writing by the time the applicable Registration
  Statement is declared effective by the SEC, and do any and all other acts
  and things which may be reasonably necessary or advisable to enable such
  Holder to consummate the disposition in each such jurisdiction of such
  Registrable Securities owned by such Holder; provided, however, that the
  Company shall not be required to (i) qualify as a foreign corporation or as
  a dealer in securities in any jurisdiction where it would not otherwise be
  required to qualify but for this Section 4(d), (ii) file any general
  consent to service of process or (iii) subject itself to taxation in any
  such jurisdiction if it is not so subject;
 
    (e) notify each Holder of Registrable Securities (and the broker referred
  to in the second sentence of Section 2.2(f) of the Purchase Agreement)
  promptly and, if required by such Holder, confirm such
 
                                       3

  advice in writing (i) when a Registration Statement has become effective
  and when any post-effective amendments and supplements thereto become
  effective, (ii) of any request by the SEC or any state securities authority
  for amendments and supplements to a Registration Statement and Prospectus
  or for additional information after the Registration Statement has become
  effective, (iii) of the issuance by the SEC or any state securities
  authority of any stop order suspending the effectiveness of a Registration
  Statement or the initiation of any proceedings for that purpose, (iv) if,
  between the effective date of a Registration Statement and the closing of
  any sale of Registrable Securities covered thereby, if the Company receives
  any notification with respect to the suspension of the qualification of the
  Registrable Securities for sale in any jurisdiction or the initiation of
  any proceeding for such purpose and (v) of the happening of any event
  during the period a Registration Statement is effective which makes any
  statement made in such Registration Statement or the related Prospectus
  untrue in any material respect or which requires the making of any changes
  in such Registration Statement or Prospectus in order to make the
  statements therein not misleading;
 
    (f) make every reasonable effort to obtain the withdrawal of any order
  suspending the effectiveness of a Registration Statement at the earliest
  possible moment;
 
    (g) furnish to each Holder of Registrable Securities and to the
  Purchasers, without charge, at least one conformed copy of each
  Registration Statement and any post-effective amendment thereto (with
  documents incorporated therein by reference or exhibits thereto);
 
    (h) cooperate with the selling Holders of Registrable Securities to
  facilitate the timely preparation and delivery of certificates representing
  Registrable Securities to be sold pursuant to such Registration Statement
  and not bearing any restrictive legends and registered in such names as the
  selling Holders may reasonably request at least two Business Days prior to
  the closing of any sale of Registrable Securities;
 
    (i) upon the occurrence of any event contemplated by Section 4(e)(v)
  hereof, use reasonable efforts to prepare a supplement or post-effective
  amendment to a Registration Statement or the related Prospectus or any
  document incorporated therein by reference or file any other required
  document so that, as thereafter delivered to the purchasers of the
  Registrable Securities, such Prospectus will not contain any untrue
  statement of a material fact or omit to state a material fact necessary to
  make the statements therein, in light of the circumstances under which they
  were made, not misleading. The Company agrees to notify each Holder to
  suspend use of the Prospectus as soon as reasonably practicable and each
  Holder hereby agrees to suspend use of the Prospectus until the Company has
  amended or supplemented the Prospectus to correct such misstatement or
  omission. At such time as such public disclosure is otherwise made or the
  Company determines in good faith that such disclosure is not necessary, the
  Company agrees promptly to notify each Holder of such determination, to
  amend or supplement the Prospectus if necessary to correct any untrue
  statement or omission therein and to furnish each Holder such numbers of
  copies of the Prospectus as so amended or supplemented as each Holder may
  reasonably request;
 
    (j) a reasonable time prior to the filing of any Registration Statement,
  any Prospectus, any amendment to a Registration Statement or amendment or
  supplement to a Prospectus or any document which is to be incorporated by
  reference into a Registration Statement or a Prospectus after initial
  filing of a Registration Statement, provide copies of such documents to the
  Holders and make available for discussion of such document the
  representatives of the Company as shall be reasonably requested by the
  Holders of Registrable Securities;
 
    (k) obtain a CUSIP number for the Common Stock; and
 
    (l) shall use its best efforts to cause the Registrable Securities to be
  listed on the national securities exchange on which the Common Stock is
  then listed.
 
  The Company may, as a condition to such Holder's participation in any
Registration Statement, require each Holder of Registrable Securities to (i)
furnish to the Company such information regarding the Holder
 
                                       4
<PAGE>
 
and the proposed distribution by such Holder of such Registrable Securities as
the Company may from time to time reasonably request in writing and (ii) agree
in writing to be bound by this Agreement.
 
  5. Registration Expenses. (a) All fees and expenses incident to the
performance of or compliance with this Agreement by the Company shall be borne
by the Company, whether or not the Registration Statement is filed or becomes
effective, including, without limitation, (i) all registration and filing fees
(including, without limitation, (A) fees with respect to filings required to be
made with the National Association of Securities Dealers, Inc. in connection
with an underwritten offering and (B) fees and expenses of compliance with
state securities or Blue Sky laws (including, without limitation, reasonable
fees and disbursements of counsel in connection with Blue Sky qualifications of
the Registrable Securities and determination of the eligibility of the
Registrable Securities for investment under the laws of such jurisdictions),
(ii) printing expenses (including, without limitation, expenses of printing
certificates for Registrable Securities in a form eligible for deposit with The
Depository Trust Company and of printing prospectuses if the printing of
prospectuses is required by the managing underwriters, if any,) (iii)
messenger, telephone and delivery expenses, (iv) fees and disbursements of
counsel for the Company, and fees and disbursements of one special counsel for
the sellers of Registrable Securities (subject to Section 5(b) hereof), (v)
fees and disbursements of all independent certified public accountants for the
Company, (vi) Securities Act liability insurance, if the Company desires such
insurance, (vii) fees and expenses of all other Persons retained by the
Company, (viii) internal expenses of the Company (including, without
limitation, all salaries and expenses of officers and employees of the Company
performing legal or accounting duties), (ix) the expense of any annual audit,
(x) the fees and expenses incurred in connection with the listing of the
securities to be registered on any securities exchange and (xi) the expenses
relating to printing, word processing and distributing all Registration
Statements, underwriting agreements, securities sales agreements, indentures
and any other documents necessary in order to comply with this Agreement.
 
  (b) The Company shall reimburse the Holders of the Registrable Securities
being registered in a registration for the reasonable fees and disbursements of
any one firm chosen by the Holders of a Majority of the Registrable Securities
in connection with the registration of the Registrable Securities.
 
  6. Indemnification and Contribution. (a) The Company agrees to indemnify and
hold harmless each Holder and each person, if any, who controls such Holder
within the meaning of either Section 15 of the Securities Act or Section 20 of
the Exchange Act, or is under common control with, or is controlled by, such
Holder, and each of their respective directors, officers, partners, agents and
employees from and against all losses, claims, damages and liabilities
(including, without limitation, any legal or other expenses reasonably incurred
by any Holder or any such controlling or affiliated person, director, officer,
partner, agent or employee in connection with defending or investigating any
such action or claim) caused by any untrue statement or alleged untrue
statement of a material fact contained in any Registration Statement (or any
amendment thereto) pursuant to which Registrable Securities were registered
under the Securities Act, or caused by any omission or alleged omission to
state therein a material fact necessary to make the statements therein not
misleading, or caused by any untrue statement or alleged untrue statement of a
material fact contained in any Prospectus (as amended or supplemented if the
Company shall have furnished any amendments or supplements thereto), or caused
by any omission or alleged omission to state therein a material fact necessary
to make the statements therein in light of the circumstances under which they
were made not misleading, except insofar as such losses, claims, damages or
liabilities are caused by any such untrue statement or omission or alleged
untrue statement or omission based upon information relating to any Holder
furnished to the Company in writing by such Holder expressly for use in any
such Registration Statement or Prospectus.
 
  (b) Each Holder agrees, severally and not jointly, to indemnify and hold
harmless the Company, its directors, its officers and each person, if any, who
controls the Company within the meaning of either Section 15 of the Securities
Act or Section 20 of the Exchange Act to the same extent as the foregoing
indemnity from the Company to such Holder, but only with reference to
information relating to such Holder furnished
 
                                       5
<PAGE>
 
to the Company in writing by such Holder expressly for use in any Registration
Statement (or any amendment thereto) or any Prospectus (or any amendment or
supplement thereto).
 
  (c) In case any proceeding (including any governmental investigation) shall
be instituted involving any person in respect of which indemnity may be sought
pursuant to either paragraph (a) or (b) above, such person (the "indemnified
party") shall promptly notify the person against which such indemnity may be
sought (the "indemnifying party") in writing and the indemnifying party, upon
request of the indemnified party, shall retain counsel reasonably satisfactory
to the indemnified party to represent the indemnified party and any others the
indemnifying party may designate in such proceeding and shall pay the
reasonable fees and disbursements of such counsel relating to such proceeding.
In any such proceeding, any indemnified party shall have the right to retain
its own counsel, but the fees and expenses of such counsel shall be at the
expense of such indemnified party unless (i) the indemnifying party and the
indemnified party shall have mutually agreed in writing to the retention of
such counsel or (ii) the indemnifying party fails promptly to assume the
defense of such proceeding or fails to employ counsel reasonably satisfactory
to such indemnified party or parties or (iii) the named parties to any such
proceeding (including any impleaded parties) include both such indemnified
party or parties and the indemnifying parties or an affiliate of the
indemnifying parties or such indemnified parties, and there may be one or more
defenses available to such indemnified party or parties that are different from
or additional to those available to the indemnifying parties, in which case, if
such indemnified party or parties notifies the indemnifying parties in writing
that it elects to employ separate counsel of its choice at the expense of the
indemnifying parties, the indemnifying parties shall not have the right to
assume the defense thereof and such counsel shall be at the expense of the
indemnifying parties, it being understood, however, that unless there exists a
conflict among indemnified parties, the indemnifying parties shall not, in
connection with any one such proceeding or separate but substantially similar
or related proceedings in the same jurisdiction, arising out of the same
general allegations or circumstances, be liable for the fees and expenses of
more than one separate firm of attorneys (together with appropriate local
counsel) at any time for such indemnified party or parties. The indemnifying
party shall not be liable for any settlement of any proceeding effected without
its written consent but, if settled with such consent or if there be a final
judgment for the plaintiff, the indemnifying party agrees to indemnify the
indemnified party from and against any loss or liability by reason of such
settlement or judgment. No indemnifying party shall, without the prior written
consent of the indemnified party, effect any settlement of any pending or
threatened proceeding in respect of which any indemnified party is a party, and
indemnity could have been sought hereunder by such indemnified party, unless
such settlement includes an unconditional release of such indemnified party
from all liability on claims that are the subject matter of such proceeding.
 
  (d) To the extent the indemnification provided for in paragraph (a) or (b) of
this Section 6 is unavailable to an indemnified party or insufficient in
respect of any losses, claims, damages or liabilities, then each indemnifying
party under such paragraph, in lieu of indemnifying such indemnified party
thereunder, shall contribute to the amount paid or payable by such indemnified
party as a result of such losses, claims, damages or liabilities (i) in such
proportion as is appropriate to reflect the relative benefits received by, in
the case of a claim under paragraph (a) of this Section 6, the Company on the
one hand and the Holders on the other hand and, in the case of a claim under
paragraph (b) of this Section 6, by the Company on the one hand and each Holder
who may be an indemnifying party on the other hand from the offering of such
Registrable Securities or (ii) if the allocation provided by clause (i) above
is not permitted by applicable law, in such proportion as is appropriate to
reflect not only the relative benefits referred to in clause (i) above but also
the relative fault, in the case of a claim under paragraph (a) of this Section
6, of the Company on the one hand and the Holders on the other hand and, in the
case of a claim under paragraph (b) of this Section 6, by the Company on the
one hand and each Holder who may be an indemnifying party on the other hand in
connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative fault of the Company on the one hand and the
Holders on the other hand shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact
relates to information supplied by the Company or by the
 
                                       6
<PAGE>
 
Holders and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.
 
  (e) The Company and each Holder agrees that it would not be just or equitable
if contribution pursuant to this Section 6 were determined by pro rata
allocation or by any other method of allocation that does not take account of
the equitable considerations referred to in paragraph (d) above. The amount
paid or payable by an indemnified party as a result of the losses, claims,
damages and liabilities referred to in paragraph (d) above shall be deemed to
include, subject to the limitations set forth above, any legal or other
expenses reasonably incurred (and not otherwise reimbursed) by such indemnified
party in connection with investigating or defending any such action or claim.
No person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation. The remedies provided
for in this Section 6 are not exclusive and shall not limit any rights or
remedies which may otherwise be available to any indemnified party at law or in
equity.
 
  (f) At the request of the broker designated pursuant to Section 2.3 of the
Purchase Agreement, the Company shall enter into customary indemnification
arrangements with such broker.
 
  7. Limitation of Remedies. Notwithstanding anything to the contrary contained
herein, in the event that the Company fails to file a Registration Statement,
fails to keep such Registration Statement effective, or fails to take any other
action provided for herein, in each case to the extent required by the terms
hereof, the sole remedy of each Holder of Registrable Securities (except with
respect to any obligation of the Company under Section 5 or 6 hereof) shall be
to enforce its rights set forth in Section 2.2(f) of the Purchase Agreement.
 
  8. Miscellaneous.
 
  (a) NO INCONSISTENT AGREEMENTS. The Company has not entered into nor will the
Company on or after the date of this Agreement enter into any agreement which
is inconsistent with the rights granted to the Holders of Registrable
Securities in this Agreement or otherwise conflicts with the provisions hereof.
The rights granted to the Holders hereunder do not in any way conflict with and
are not inconsistent with the rights granted to the holders of the Company's
other issued and outstanding securities, if any, under any such agreements.
 
  (b) AMENDMENTS AND WAIVERS. The provisions of this Agreement, including the
provisions of this sentence, may not be amended, modified or supplemented, and
waivers or consents to departures from the provisions hereof may not be given
unless the Company has obtained the written consent of Holders of at least a
Majority of the outstanding Registrable Securities affected by such amendment,
modification, supplement, waiver or consent; provided, however, a waiver or
consent to departure from the provisions hereof that relates exclusively to the
rights of Holders of Registrable Securities whose securities are being sold
pursuant to a registration statement and that does not directly or indirectly
affect the rights of other Holders of Registrable Securities may be given by
the Holders of a majority of the Registrable Securities proposed to be sold.
 
  (c) NOTICES. All notices and other communications provided for or permitted
hereunder shall be made in writing by hand delivery, registered first-class
mail, telex, telecopier, or any courier guaranteeing overnight delivery (i) if
to a Holder, at the most current address given by such Holder to the Company by
means of a notice (with copies) given in accordance with the provisions of this
Section 8(c), which address initially is with respect to the Purchasers, the
addresses set forth in the Purchase Agreement; and (ii) if to the Company, at
the Company's address set forth in the Purchase Agreement.
 
  All such notices and communications shall be deemed to have been duly given:
at the time delivered by hand, if personally delivered, five Business Days
after being deposited in the mail, postage prepaid, if mailed;
 
                                       7
<PAGE>
 
when answered back, if telexed; when receipt is acknowledged, if telecopied;
and on the next Business Day, if timely delivered to an air courier
guaranteeing overnight delivery.
 
  (d) SUCCESSORS AND ASSIGNS. This Agreement shall inure to the benefit of and
be binding upon the successors, assigns and transferees of each of the parties,
including, without limitation and without the need for an express assignment,
any subsequent Holder; provided, however, that nothing herein shall be deemed
to permit any assignment, transfer or other disposition of Registrable
Securities in violation of the terms of the Purchase Agreement. If any
transferee of any Holder shall acquire Registrable Securities, in any manner,
whether by operation of law or otherwise, such Registrable Securities shall be
held subject to all of the terms of this Agreement, and by taking and holding
such Registrable Securities such person shall be conclusively deemed to have
agreed to be bound by and to perform all of the terms and provisions of this
Agreement and such person shall be entitled to receive the benefits hereof.
 
  (e) COUNTERPARTS. This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.
 
  (f) HEADINGS. The headings in this Agreement are for convenience of reference
only and shall not limit or otherwise affect the meaning hereof.
 
  (g) GOVERNING LAW. This Agreement shall be governed by and construed in
accordance with the laws of the State of New York, without regard to principles
of conflicts of laws.
 
  (h) SEVERABILITY. In the event that any one or more of the provisions
contained herein, or the application thereof in any circumstance, is held
invalid, illegal or unenforceable, the validity, legality and enforceability of
any such provision in every other respect and of the remaining provisions
contained herein shall not be affected or impaired thereby.

  This Certificate relates to     shares of Common Stock held by

  The Transferor has requested the Transfer Agent by written order to exchange
or register the transfer of a certificate or certificates representing shares

  In connection with such request, the Transferor does hereby certify that
Transferor is familiar with the Common Stock Registration Rights Agreement
("Agreement") relating to the shares of Common Stock and the restrictions on
transfers thereof as provided in Section 3 of such Agreement, and that the
transfers of shares of Common Stock requested hereby does not require

  [_] Such shares of Common Stock are being transferred pursuant to an
effective registration statement under the Securities Act.
 
  [_] Such shares of Common Stock are being transferred in reliance on and in
compliance with an exemption from the registration requirements of the
Securities Act. If this Certificate contains the restrictive legend required by
Section 3 of the Agreement, an opinion of counsel to the effect that such
transfer does not require registration under the Securities Act accompanies
this Certificate.
