          CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING STATEMENTS
 
  This Prospectus Supplement and the accompanying Prospectus and the documents
incorporated by reference therein contain forward-looking statements within
the meaning of Section 27A of the Securities Act of 1933, as amended (the
"Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"). These forward-looking statements are subject to
risks and uncertainties that could cause actual results to differ materially
from those projected in these statements. Some of the important factors that
may influence possible differences are continued competitive factors and
pricing pressures, construction activity, interest rate movements, issues
involving implementation of new business systems, achievement of expected cost
reductions and asbestos litigation. Further information on factors that could
affect the Company's financial and other results are included in the Company's
Annual Report on Form 10-K for the fiscal year ended December 31, 1997 (the
"1997 Form 10-K") and the Company's quarterly report on Form 10-Q for the
quarter ended March 31, 1998 filed with the Securities and Exchange Commission
and incorporated herein by reference.
 
                                  THE COMPANY
 
  Owens Corning is a world leader in building materials and high performance
glass fiber composites. The Company's products are used in industries such as
home improvement, new construction, transportation, marine, aerospace, energy,
appliance and electronics. The Company is a market leader in each of the North
American markets for insulation, roofing and vinyl siding, and is the world
leader in composites. In 1997, the Building Materials segment accounted for
74% of the Company's total sales and the Composite Materials segment accounted
for 26% of total sales.
 
BUILDING MATERIALS
 
  The Company's Building Materials business sells a variety of building and
home improvement products in three major categories: (i) glass fiber, foam and
mineral wool insulation, (ii) roofing materials, and (iii) exterior products
for the home, such as vinyl and metal siding and accessories, vinyl windows
and patio doors, rainware (gutters and downspouts), cast stone building
products and housewrap. The Owens Corning name, its trademarked color PINK and
licensed Pink Panther icon and its FIBERGLAS(R) trademark enjoy strong brand
recognition with homeowner consumers in the building materials market.
 
COMPOSITE MATERIALS
 
  The Company is the world's leading producer of glass fiber materials used in
composites. Composites are fabricated material systems made up of two or more
components (e.g., plastic resin and glass fiber) used in various applications
to replace traditional materials, such as aluminum, wood, and steel. The
global composites industry has expanded to include thousands of end-use
applications. The primary end-use markets that the Company serves are
construction, transportation, and electrical/electronics. In the construction
market, the major end-use application for glass fiber is asphalt roofing
shingles. In the transportation market, glass fiber is used mainly in
automotive and truck parts, a use that is continuing to grow as the amount of
composite materials per vehicle increases. Within the electrical/electronics
markets, glass fiber is used extensively in printed circuit boards made for
the consumer electronics, transportation and telecommunications industries.

GROWTH STRATEGY
 
  Owens Corning's growth agenda has focused on increasing sales and earnings
by (i) acquiring businesses with products that can be sold through existing or
complementary distribution channels, (ii) achieving productivity improvements
in existing and acquired businesses and (iii) entering new high-growth
markets. The Company is implementing two major initiatives, System Thinking
and Advantage 2000, to achieve productivity improvements across all
businesses. System Thinking for the Home(TM) leverages Owens Corning's broad
product offering and strong brand recognition to increase its share of the
building materials and home improvement markets. This systems approach
represents a shift from product-oriented selling to providing systems-driven
solutions that combine the Company's insulation, roofing, exterior and sound
control systems, to provide a high performance, cost-effective building
"envelope" for the home. In addition, Owens Corning is implementing Advantage
2000, a fully integrated business technology system designed to reduce costs
and improve business processes.
 
  The Company has grown its sales from nearly $3.4 billion in 1994 to
approximately $5.0 billion on a pro forma basis giving effect to acquisitions
made in 1997. Acquisitions have been a significant component of that growth.
Since 1994, the Company completed 17 acquisitions for an aggregate purchase
price of over $1.2 billion. The Company's acquisitions have broadened its
lines of business to include siding, accessories and other home exteriors and
have diversified its materials portfolio beyond fiber glass to include
polymers such as vinyl and styrene, and metal and stone. In 1997, the Company
completed its two largest acquisitions by acquiring Fibreboard Corporation
("Fibreboard") and AmeriMark Building Products, Inc. ("AmeriMark"), making
Owens Corning the leader in the U.S. vinyl siding, siding accessories and cast
stone markets, as well as a large speciality distributor in North America
through nearly 200 company-owned distribution centers.
 
PRICING ENVIRONMENT
 
  Despite improvements in the Company's strategic position in 1997, the
Company experienced a highly competitive pricing environment in several of its
product markets that negatively impacted financial results. In North America,
insulation pricing decreased by approximately 10 percent over the course of
1997 and worldwide composite pricing decreased by approximately 6 percent from
late 1996 through 1997. Income from operations for 1997 was adversely impacted
by approximately $87 million as a result of price declines in insulation
products and approximately $64 million as a result of price declines affecting
Composite Materials. Offset by small price increases in other businesses, the
net effect of price on 1997 income from operations was approximately $142
million.
 
  In the first and second quarters of 1998, the Company announced price
increases applicable to its residential and industrial insulation products and
certain residential roofing products.
 
                              RECENT DEVELOPMENTS
 
RESTRUCTURING TO IMPROVE PROFITABILITY
 
  As a result of the growth in Owens Corning's business through acquisitions
and the significant pricing pressure the Company experienced in 1997, the
Company has implemented a strategic restructuring program designed to improve
profitability. The restructuring program will streamline the organization,
reduce overhead, enhance manufacturing productivity and close high cost
manufacturing facilities, resulting in a 9 percent reduction (approximately
2,200 people) in the work force worldwide. The Company expects to decrease
operating costs by approximately $100 million in 1998, and by an additional
$75 million when the program is fully implemented in 1999, resulting in
ongoing pre-tax savings of approximately $175 million per year. In addition to
the restructuring savings of $100 million, the Company expects to achieve
approximately $30 million in additional synergies and cost savings in 1998
from integrating the Fibreboard and AmeriMark acquisitions.
 
  The restructuring program and other cost reduction initiatives are expected
to result in a pre-tax charge of $250 million. Approximately $143 million of
the charge was recorded in the fourth quarter of 1997, which is reflected in
the results of operations for the year ended December 31, 1997. Approximately
$95 million of the
 
                                      S-3
<PAGE>
 
charge was recorded in the first quarter of 1998 and the balance is expected
to be charged during the remainder of the year.
 
DIVESTITURE PROGRAM
 
  The Company is also focused on divesting certain non-strategic operations to
reduce debt and focus its efforts on core businesses. The divestiture program
is expected to result in net cash proceeds during 1998 of between $400 and
$500 million. In the first quarter of 1998, the Company completed the sale of
the assets of Pabco, a producer of molded calcium silicate insulation,
fireproofing board and metal jacketing, acquired as part of the Fibreboard
acquisition in 1997, and its 50 percent interest in Alpha/Owens Corning LLC, a
manufacturer and marketer of unsaturated polyester and vinylester resins, for
approximately $140 million. In the second quarter of 1998, the Company
announced that it is exploring the possible sale of its Glass Fiber Yarns and
Specialty Materials portion of its Composites Materials business. The Company
continues to evaluate other divestiture opportunities.
 
SECOND QUARTER 1998 RESULTS
 
  Net sales were $1,286 million, an increase of 26 percent over $1,017 million
recorded in the second quarter of 1997. Acquisitions made in the Company's
Exterior Systems Business during the second half of 1997 were the primary
contributors to the sales increase. Net income was $59 million, or $1.02 per
diluted share in the second quarter, compared to $63 million, or $1.11 per
diluted share reported for the second quarter of 1997.
 
  For the first six months of 1998, net sales were $2,423 million, up 28
percent from $1,892 million in the first half of 1997. Net income was $67
million or $1.20 per diluted share, compared to $105 million or $1.88 per
diluted share in the first half of 1997. Net income for the six months ended
June 30, 1998 included the following items from the first quarter of 1998: a
pre-tax charge of $95 million ($63 million after-tax) for restructuring and
other actions, a pre-tax gain of $84 million ($52 million after-tax) from the
sale of the Company's 50 percent interest in Alpha/Owens Corning LLC and a tax
credit of $13 million associated with Asia Pacific operations. Income from
operations for the six months ended June 30, 1998 was $173 million, compared
to $188 million in the first six months of 1997.
 
 BUILDING MATERIALS
 
  Sales in Building Materials were $995 million for the second quarter of
1998, up 40 percent over the second quarter of 1997. Excluding the Exterior
Systems acquisitions made in the second half of 1997, second quarter sales in
Building Materials were down slightly over the year-ago quarter primarily due
to price.
 
  Volume was basically flat in Building Materials, with an unfavorable
quarter-over-quarter price comparison in the Insulation Systems Business.
 
  Building Materials income from operations was $91 million in the second
quarter of 1998, up 23 percent compared to the second quarter of 1997, despite
the unfavorable price environment.
 
  Although vinyl siding prices were down, margins were maintained in the
Exterior Systems Business due to lower raw material costs, higher volume and
consolidation synergies.
 
 COMPOSITE MATERIALS
 
  Sales in Composite Materials were $291 million in the second quarter of
1998, down 4 percent from the second quarter of 1997, due primarily to volume
declines in the United States. Demand for electronic circuit boards slowed at
the end of the second quarter and sales were impacted by some order
cancellations due to the General Motors strike.
 
  Volume was up in Europe but prices have not recovered from the declines in
1997. Sales were down significantly in Latin America due to a furnace problem
in the Company's Brazilian operations, however Asia Pacific volumes were
stable and the Company continues to grow its share in the region.
 
  Composites income from operations increased to $59 million in the second
quarter of 1998, up 18 percent on slightly lower sales compared to the second
quarter of 1997 due to productivity improvements and cost reductions.

                                USE OF PROCEEDS
 
  The net proceeds from the sale of the Debentures offered hereby, after
payment of expenses related to the offering and underwriting discounts and
commissions, are expected to be approximately $395 million. The Company
intends to use the net proceeds to fund the cash tender offers commenced on
July 21, 1998 (the "Tender Offers") for $150,000,000 aggregate principal
amount of the Company's 8 7/8% Debentures due 2002 and $150,000,000 aggregate
principal amount of the Company's 9 3/8% Debentures due 2012 and $150,000,000
aggregate principal amount of O.C. Funding B.V.'s 10% Debentures due 2001 or
to repay a portion of the outstanding borrowings under its revolving credit
agreement dated as of June 26, 1997, as amended (the "Credit Agreement"). The
Company intends to draw $100 million under the Credit Agreement to repay the
principal of its 9.8% Debentures due August 15, 1998 when they mature on
August 15, 1998. The Credit Agreement has a maximum commitment of $1.8 billion
and provides for varying terms and interest rates. The weighted average
interest rate under the Credit Agreement was 6.0% at June 30, 1998. Borrowings
under the Credit Agreement were used to repay the Company's previous U.S. and
Canadian credit facilities and select short-term debt and to fund the
acquisition of Fibreboard.

  For purposes of the calculation of the ratio of earnings to fixed charges,
earnings represent net income before fixed charges, provision for taxes on
income, undistributed earnings of equity basis investments, extraordinary
losses from early retirement of debt and the cumulative effect of accounting
changes. Fixed charges include interest expense, the portion (one-third) of
rental expense deemed to be representative of interest and preferred stock
dividends requirements of consolidated subsidiaries. The Company's earnings in
1996 were insufficient to cover fixed charges by approximately $600 million.

                              ASBESTOS LITIGATION
 
  Owens Corning is a co-defendant with other former manufacturers,
distributors and installers of products containing asbestos and with miners
and suppliers of asbestos fibers in personal injury litigation. The personal
injury claimants generally allege injuries to their health caused by
inhalation of asbestos fibers from Owens Corning's products. Most of the
claimants seek punitive damages as well as compensatory damages. Virtually all
of the asbestos-related lawsuits against Owens Corning 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.
 
  For a discussion of the Company's asbestos liabilities, see Note 22 to the
Company's Consolidated Financial Statements for the year ended December 31,
1997 and Note 11 to the Company's Consolidated Financial Statements for the
quarter ended March 31, 1998 incorporated by reference in the accompanying
Prospectus.

payable, the transfer of Debentures will be registrable and the Debentures may
be presented for exchange, at the office of the Trustee located at 101 Barclay
Street, Floor 21W., New York, NY 10286, attention: Corporate Trust, Trustee
Administration. So long as the Debentures are represented by Book Entry
Securities, the interest payable on the Debentures will be paid to Cede & Co.,
the nominee of The Depository Trust Company ("DTC"), the Depositary for the
Debentures, or its registered assigns as the registered owner of the Book
Entry Securities, by wire transfer of immediately
 
                                      S-6
<PAGE>
 
available funds on each of the applicable interest payment dates, not later
than 2:30 p.m. Eastern Standard Time. If the Debentures are no longer
represented by Book Entry Securities, payment of interest may, at the option
of the Company, be made by check mailed to the address of the Person entitled
thereto.
 
  The Debentures will not be subject to any sinking fund.
 
OPTIONAL REDEMPTION
 
  The Debentures will be redeemable, in whole or in part, at the option of the
Company at any time at a redemption price equal to the greater of (i) 100% of
the principal amount of such Debentures or (ii) the sum of the present values
of the remaining scheduled payments of principal and interest thereon (not
including the portion of any such payments of interest accrued as of the
redemption date) discounted to the redemption date on a semiannual basis
(assuming a 360-day year consisting of twelve 30-day months) at the Adjusted
Treasury Rate (determined on the third Business Day preceding such redemption
date), plus, in each case, accrued and unpaid interest thereon to the
redemption date.
 
  "Adjusted Treasury Rate" means the arithmetic mean of the yields under the
heading "Week Ending" published in the Statistical Release most recently
published prior to the date of determination under the caption "Treasury
Constant Maturities" for the maturity (rounded to the nearest month)
corresponding to the remaining life to maturity, as of the redemption date, of
the principal being redeemed, plus 0.375%. If no maturity set forth under such
heading exactly corresponds to the maturity of such principal, yields for the
two published maturities most closely corresponding to the maturity of such
principal shall be calculated pursuant to the immediately preceding sentence,
and the Adjusted Treasury Rate shall be interpolated or extrapolated from such
yields on a straight-line basis, rounding in the relevant period to the
nearest month.
 
  "Statistical Release" means the statistical release designated "H.15(519)"
or any successor publication which is published weekly by the Federal Reserve
System and which establishes yields on actively-traded United States
government securities adjusted to constant maturities, or, if such statistical
release is not published at the time of any determination under the terms of
the Debentures, then such other reasonably comparable index which shall be
designated by the Company.
 
  Notice of any redemption will be mailed at least 30 days but not more than
60 days before the redemption date to each holder of the Debentures to be
redeemed.
 
  Unless the Company defaults in payment of the redemption price, on and after
the redemption date, interest will cease to accrue on the Debentures or
portions thereof called for redemption.
 
BOOK ENTRY, DELIVERY AND FORM
 
  The Debentures will be represented by Book Entry Securities that will be
deposited with, or on behalf of, DTC and registered in the name of Cede & Co.,
the nominee of DTC.
 
  DTC has advised the Company as follows: DTC is a limited-purpose trust
company organized under the New York Banking Law, a "banking organization"
within the meaning of the New York Banking Law, a member of the Federal
Reserve System, a "clearing corporation" within the meaning of the New York
Uniform Commercial Code and a "clearing agency" registered pursuant to the
provisions of Section 17A of the Exchange Act. DTC was created to hold
securities of its participating organizations ("participants") and to
facilitate the clearance and settlement of securities transactions, such as
transfers and pledges, among its participants in such securities through
electronic computerized book-entry changes in accounts of the participants,
thereby eliminating the need for physical movement of securities certificates.
Participants include securities brokers and dealers (including the
Underwriters), banks, trust companies, clearing corporations and certain other
organizations, some of whom (and/or their representatives) own DTC. Access to
DTC's book-entry system is also available to others, such as banks, brokers,
dealers and trust companies that clear through or maintain a
 
                                      S-7
<PAGE>
 
custodial relationship with a participant, either directly or indirectly.
Persons who are not participants may beneficially own securities held by DTC
only through participants.
 
  Unless and until they are exchanged in whole or in part for certificated
Debentures, in definitive form, the Book Entry Securities may not be
registered for transfer or exchange except as a whole by DTC to a nominee of
DTC or by a nominee of DTC to DTC or another nominee of DTC or by DTC or any
such nominee to a successor depository or a nominee of such successor
depository.
 
  A further description of DTC's procedures with respect to the Debentures is
set forth in the accompanying Prospectus under the heading "Description of
Debt Securities--Book Entry Debt Securities."
 
DEFEASANCE
 
  The provisions described under "Description of Debt Securities--Defeasance
of Offered Debt Securities or Certain Covenants in Certain Circumstances" in
the accompanying Prospectus are applicable to the Debentures.
 
                                 UNDERWRITING
 
  Under the terms and subject to the conditions contained in an Underwriting
Agreement dated July 22, 1998 (the "Underwriting Agreement") and the related
Pricing Agreement dated July 22, 1998 (the "Pricing Agreement"), the
Underwriters named below (the "Underwriters") have severally but not jointly
agreed to purchase from the Company the following respective principal amounts
of the Debentures:

</TABLE>
 
  The Underwriting Agreement provides that the obligations of the Underwriters
are subject to certain conditions precedent and that the Underwriters will be
obligated to purchase all the Debentures, if any are purchased. The
Underwriting Agreement provides that, in the event of a default by an
Underwriter, in certain circumstances the purchase commitments of non-
defaulting Underwriters may be increased or the Underwriting Agreement may be
terminated.
 
  The Company has been advised by the Underwriters that the Underwriters
propose to offer the Debentures to the public initially at the public offering
price set forth on the cover page of this Prospectus Supplement and to certain
dealers at such price less a concession of 0.50% of the principal amount per
Debenture, and the Underwriters and such dealers may allow a discount of 0.25%
of such principal amount per Debenture on sales to certain other dealers.
After the initial public offering, the public offering price and concession
and discount to dealers may be changed by the Underwriters.
 
  The Debentures are a new issue of securities with no established trading
market. The Underwriters have advised the Company that they intend to act as
market makers for the Debentures. However, the Underwriters are not obligated
to do so and may discontinue any market making at any time without notice. No
assurance can be given as to the liquidity of the trading market for the
Debentures.

  The Bank of New York, Royal Bank of Canada, Societe Generale, The Bank of
Nova Scotia and Credit Suisse First Boston are affiliates of BNY Capital
Markets, Inc., RBC Dominion Securities Corporation, SG Cowen, Scotia Capital
Markets (USA) Inc. and Credit Suisse First Boston Corporation, respectively,
and are lenders under the Credit Agreement and have in the past, and may in
the future, engage in other commercial banking transactions with the Company.
The Company may use a portion of the net proceeds of this offering to repay in
part amounts outstanding under the Credit Agreement, and such lenders may
receive in excess of 10% of such net proceeds (not including underwriting
compensation). Because more than 10% of the net proceeds of the offering may
be received by entities affiliated with members of the National Association of
Securities Dealers, Inc. (the "NASD") participating in the offering made
hereby, the offering is being conducted pursuant to Rule 2710(c)(8) of the
Conduct Rules of the NASD. In addition, Merrill Lynch, Pierce, Fenner & Smith
Incorporated is acting as dealer manager of the Tender Offers. The Bank of New
York is also Trustee under the Indenture.
 
  The Company has agreed to indemnify the Underwriters against certain
liabilities, including civil liabilities under the Securities Act, or
contribute to payments which the Underwriters may be required to make in
respect thereof.
 
  The Underwriters may engage in over-allotment, stabilizing transactions,
syndicate covering transactions and penalty bids. Over-allotment involves
syndicate sales in excess of the offering size, which creates a syndicate
short position. Stabilizing transactions permit bids to purchase the
underlying security so long as the stabilizing bids do not exceed a specified
maximum. Syndicate covering transactions involve purchases of the Debentures
in the open market after the distribution has been completed in order to cover
syndicate short positions. Penalty bids permit the Underwriters to reclaim a
selling concession from a broker-dealer when the Debentures originally sold by
such broker-dealer are purchased in a syndicate covering transaction to cover
syndicate short positions. Such stabilizing transactions, syndicate covering
transactions and penalty bids may cause the price of the Debentures to be
higher than it would otherwise be in the absence of such transactions.
 
                         NOTICE TO CANADIAN RESIDENTS
 
RESALE RESTRICTIONS
 
  The distribution of the Debentures in Canada is being made only on a private
placement basis exempt from the requirement that the Company prepare and file
a prospectus with the securities regulatory authorities in each province where
trades of Debentures are effected. Accordingly, any resale of the Debentures
in Canada must be made in accordance with applicable securities laws, which
will vary depending on the relevant jurisdiction, and which may require
resales to be made in accordance with available statutory exemptions or
pursuant to a discretionary exemption granted by the applicable Canadian
securities regulatory authority. Purchasers are advised to seek legal advice
prior to any resale of the Debentures.
 
REPRESENTATIONS OF PURCHASERS
 
  Each purchaser of Debentures in Canada who receives a purchase confirmation
will be deemed to represent to the Company and the dealer from whom such
purchase confirmation is received that (i) such purchaser is entitled under
applicable provincial securities laws to purchase such Debentures without the
benefit of a prospectus qualified under such securities laws, (ii) where
required by law, that such purchaser is purchasing as principal and not as
agent, and (iii) such purchaser has reviewed the text above under "Resale
Restrictions".
 
RIGHTS OF ACTION (ONTARIO PURCHASERS)
 
  The securities being offered are those of a foreign issuer and Ontario
purchasers will not receive the contractual right of action prescribed by
section 32 of the Regulation under the Securities Act (Ontario). As a result,
Ontario purchasers must rely on other remedies that may be available,
including common law rights of
 
                                      S-9
<PAGE>
 
action for damages or rescission or rights of action under the civil liability
provisions of the U.S. federal securities laws.
 
ENFORCEMENT OF LEGAL RIGHTS
 
  All of the issuer's directors and officers as well as the experts named
herein may be located outside of Canada and, as a result, it may not be
possible for Canadian purchasers to effect service of process within Canada
upon the issuer or such persons. All or a substantial portion of the assets of
the issuer and such persons may be located outside of Canada and, as a result,
it may not be possible to satisfy a judgment against the issuer or such
persons in Canada or to enforce a judgment obtained in Canadian courts against
such issuer or persons outside of Canada.
 
NOTICE TO BRITISH COLUMBIA RESIDENTS
 
  A purchaser of Debentures to whom the Securities Act (British Columbia)
applies is advised that such purchaser is required to file with the British
Columbia Securities Commission a report within ten days of the sale of any
Debentures acquired by such purchaser pursuant to this offering. Such report
must be in the form attached to British Columbia Securities Commission Blanket
Order BOR #95/17, a copy of which may be obtained from the Company. Only one
such report must be filed in respect of Debentures acquired on the same date
and under the same prospectus exemption.
 
TAXATION AND ELIGIBILITY FOR INVESTMENT
 
  Canadian purchasers of Debentures should consult their own legal and tax
advisors with respect to the tax consequences of an investment in the
Debentures in their particular circumstances and with respect to the
eligibility of the Debentures for investment by the purchaser under relevant
Canadian Legislation.
 
                          VALIDITY OF THE DEBENTURES
 
  The validity of the Debentures offered hereby will be passed upon for the
Company by Shearman & Sterling, New York, New York and for the Underwriters by

issue these Debt Securities in any currency other than U.S. dollars. (Section
301)
 
  Debt Securities may be sold at a substantial discount below their stated
principal amount, bearing no interest or interest at a rate which at the time
of issuance is below market rates. Material U.S. federal income tax
consequences and special considerations applicable to any such Debt Securities
will be described in the Applicable Prospectus Supplement.
 
  If any index is used to determine the amount of payments of principal of,
premium, if any, or interest, if any, on any series of Debt Securities,
material U.S. federal income tax, accounting and other considerations
applicable thereto will be described in the Applicable Prospectus Supplement.
 
BOOK ENTRY DEBT SECURITIES
 
  The following description of Book Entry Securities will apply to any series
of Debt Securities except as otherwise provided in the Prospectus Supplement
relating thereto.
 
  The Debt Securities of a series may be issued in the form of one or more
Book Entry Securities that will be deposited with or on behalf of a
Depositary, which will be a clearing agent registered under the Exchange Act.
Book Entry Securities will be registered in the name of the Depositary or a
nominee of the Depositary, will be deposited with such Depositary or nominee
or a custodian therefor and will bear a legend regarding the restrictions on
exchanges and registration of transfer thereof and any such other matters as
may be provided for pursuant to the Indenture. Unless and until it is
exchanged in whole or in part for Debt Securities in definitive certificated
form, a Book Entry Security may not be transferred or exchanged except as a
whole by the Depositary for such Book Entry Security to a nominee of such
Depositary or by a nominee of such Depositary to such Depositary or another
nominee of such Depositary or by such Depositary or any such nominee to a
successor Depositary for such series or a nominee of such successor
Depositary, or except in the circumstances described in the Applicable
Prospectus Supplement. (Section 305)
 
  Upon the issuance of any Book Entry Security, and the deposit of such Book
Entry Security with or on behalf of the Depositary for such Book Entry
Security, the Depositary will credit on its book-entry registration
 
                                       6
<PAGE>
 
and transfer system the respective principal amounts of the Debt Securities
represented by such Book Entry Security to the accounts of institutions
("Participants") that have accounts with the Depositary. The accounts to be
credited will be designated by the underwriters or agents engaging in the
distribution of such Debt Securities or by the Company, if such Debt
Securities are offered and sold directly by the Company. Ownership of
beneficial interests in a Book Entry Security will be limited to Participants
or persons that may hold interests through Participants. Ownership of
beneficial interests in a Book Entry Security will be shown on, and the
transfer of that ownership will be effected only through, records maintained
by the Depositary for such Book Entry Security or by its nominee. Ownership of
beneficial interests in such Book Entry Security by persons who hold through
Participants will be shown on, and the transfer of such beneficial interests
within such Participants will be effected only through, records maintained by
such Participants. The laws of some jurisdictions require that certain
purchasers of securities take physical delivery of such securities in
definitive form. Such laws may impair the ability to transfer beneficial
interests in such a Book Entry Security.
 
  So long as the Depositary for a Book Entry Security, or its nominee, is the
owner of such Book Entry Security, such Depositary or such nominee, as the
case may be, will be considered the sole owner or holder of the Debt Security
represented by such Book Entry Security for all purposes under the Indenture.
Accordingly, each person owning a beneficial interest in such Book Entry
Security must rely on the procedures of the Depositary and, if such person is
not a Participant, on the procedures of the Participant through which such
person owns its interest, to exercise any rights of a holder under such
Indenture. The Company understands that under existing industry practices, if
it requests any action of holders or if an owner of a beneficial interest in a
Book Entry Security desires to give or take any instruction or action which a
holder is entitled to give or take under the Indenture, the Depositary would
authorize the Participants holding the relevant beneficial interests to give
or take such instruction or action, and such Participants would authorize
beneficial owners owning through such Participants to give or take such
instruction or action or would otherwise act upon the instructions of
beneficial owners holding through them.
 
  Unless otherwise specified in the Applicable Prospectus Supplement, payments
with respect to principal, premium, if any, and interest, if any, on the Debt
Securities represented by a Book Entry Security registered in the name of the
Depositary or its nominee will be made to such Depositary or its nominee, as
the case may be, as the registered owner of such Book Entry Security. The
Company expects that the Depositary for any Debt Securities represented by a
Book Entry Security, upon receipt of any payment of principal or interest in
respect of such Book Entry Security, will credit immediately Participants'
accounts with payments in amounts proportionate to their respective beneficial
interests in the Book Entry Security as shown on the records of the
Depositary. The Company also expects that payments by Participants to owners
of beneficial interests in such Book Entry Security held through such
Participants will be governed by standing instructions and customary
practices, as is now the case with securities in bearer form held for the
accounts of customers or registered in "street name", and will be the
responsibility of such Participants. None of the Company, the Trustee or any
agent of the Company or the Trustee shall have any responsibility or liability
for any aspect of the records relating to or payments made on account of
beneficial interests in any Book Entry Security, or for maintaining,
supervising or reviewing any records relating to such beneficial interests.
 
  A Book Entry Security shall be exchangeable for Debt Securities in
certificated registered form, of like tenor and of an equal aggregate
principal amount, only if (a) the Depositary notifies the Company that it is
unwilling or unable to continue as Depositary for such Book Entry Security or
if at any time the Depositary ceases to be a clearing agency registered under
the Exchange Act, (b) the Company in its sole discretion determines that such
Book Entry Security shall be exchangeable for Debt Securities in certificated
registered form or (c) there shall have occurred and be continuing an Event of
Default with respect to the Debt Securities. Any Book Entry Security that is
exchangeable pursuant to the preceding sentence shall be exchangeable for Debt
Securities registered in the name or names of such person or persons as the
Depositary shall instruct the Trustee. It is expected that such instructions
may be based upon directions received by the Depositary from its participants
with respect to ownership of beneficial interests in such Book Entry Security.

CERTAIN COVENANTS OF THE COMPANY
 
 Restrictions on Secured Debt
 
  If subsequent to the date of the initial issuance of the Debt Securities of
any series, the Company or any Subsidiary shall incur, issue, assume or
guarantee any Debt secured by a Mortgage on any Principal Property owned by
the Company or any Restricted Subsidiary or on any shares of stock or Debt of
any Restricted Subsidiary, the Company will secure, or cause such Subsidiary
to secure, such Debt Securities equally and ratably with (or prior to) such
secured Debt, unless after giving effect thereto the aggregate amount of all
such Debt so secured together with all Attributable Debt in respect of sale
and leaseback transactions involving Principal Properties owned by the Company
or a Restricted Subsidiary and otherwise prohibited by the Indenture would not
exceed 10% of the Consolidated Net Tangible Assets. This restriction will not
apply to, and therefore the following shall be excluded in computing secured
Debt for the purpose of such restriction: Debt secured by (a) Mortgages on
property of, or on any shares of stock or Debt of, any corporation existing at
the time such corporation becomes a Restricted Subsidiary, (b) Mortgages in
favor of the Company or any Restricted Subsidiary, (c) Mortgages in favor of
the United States of America, or any agency, department or other
instrumentality thereof, to secure progress, advance or other payments
pursuant to any contract or provision of any statute, (d) Mortgages on
property, shares of stock or Debt existing at the time of acquisition thereof
(including acquisition through merger or consolidation) and purchase money
Mortgages and construction cost Mortgages (including those incurred within 120
days following the purchase or completion of the property in question) and (e)
any extension, renewal or replacement of any Mortgage referred to in the
foregoing clauses (a) through (d) inclusive. The Indenture will not restrict
the incurring of unsecured Debt by the Company or its Subsidiaries.
 
 Restrictions on Sales and Leasebacks
 
  Neither the Company nor any Restricted Subsidiary may enter into any sale
and leaseback transaction involving any Principal Property owned by the
Company or any Restricted Subsidiary, the acquisition of which, or completion
of construction and commencement of full operation of which, has occurred more
than 120 days prior to such sale and leaseback transaction, unless (a) the
Company or such Restricted Subsidiary could create Debt secured by a Mortgage
on such property in accordance with the immediately preceding paragraph in an
amount equal to the Attributable Debt with respect to the sale and leaseback
transaction without equally and ratably securing the Outstanding Debt
Securities or (b) the Company, within 120 days after the sale or transfer of
such property, applies to the retirement of its Funded Debt an amount equal to
the greater of (i) the net proceeds of the sale of the Principal Property sold
and leased back pursuant to such arrangement or (ii) the fair market value of
the Principal Property so sold and leased back, subject to credits for certain
voluntary retirements of Funded Debt. This restriction will not apply to any
sale and leaseback transaction (a) between the Company and a Restricted
Subsidiary or between Restricted Subsidiaries or (b) involving a lease for a
period of three years or less.
 
  Unless otherwise indicated in the Applicable Prospectus Supplement, the
Indenture does not contain covenants specifically designed to protect holders
of Debt Securities in the event of a highly leveraged transaction,
restructuring, change in control, merger or similar transaction involving the
Company that may adversely affect holders of Debt Securities.
 
EVENTS OF DEFAULT
 
  Any one of the following events will constitute an Event of Default under
the Indenture with respect to Debt Securities of any series: (a) failure to
pay any interest on any Debt Security of that series when due, continued for
30 days; (b) failure to pay principal of or any premium on any Debt Security
of that series when due; (c) failure to deposit any sinking fund payment, when
due, in respect of any Debt Security of that series; (d) failure to perform,
or breach of, any covenant or warranty of the Company in the Indenture with
respect to Debt Securities of that series continued for 60 days after written
notice as provided in the Indenture; (e) certain
 
                                       8
<PAGE>
 
events of bankruptcy, insolvency or reorganization of the Company; or (f) any
other Event of Default provided with respect to Debt Securities of that
series. (Section 501)
 
  If any Event of Default with respect to the Debt Securities of any series at
the time outstanding occurs and is continuing, either the Trustee or the
holders of at least 25% in aggregate principal amount of the Outstanding Debt
Securities of that series may declare the principal amount (or, if the Debt
Securities of that series are Original Issue Discount Securities, such portion
of the principal amount as may be specified in the terms thereof) of all the
Debt Securities of that series to be due and payable immediately. At any time
after a declaration of acceleration with respect to Debt Securities of any
series has been made, but before a judgment or decree based on acceleration
has been obtained, the holders of a majority in aggregate principal amount of
Outstanding Debt Securities of that series may, under certain circumstances,
rescind and annul such acceleration. (Section 502)
 
  Reference is made to the Applicable Prospectus Supplement relating to any
series of Offered Debt Securities that are Original Issue Discount Securities
for the particular provisions relating to acceleration of the Stated Maturity
of a portion of the principal amount of such series of Original Issue Discount
Debt Securities upon the occurrence of an Event of Default and the
continuation thereof.
 
  The Indenture provides that, subject to the duty of the Trustee during
default to act with the required standard of care, the Trustee will be under
no obligation to exercise any of its rights or powers under the Indenture at
the request or direction of any of the holders of Debt Securities, unless such
holders shall have offered to the Trustee reasonable indemnity. (Section 603)
Subject to such provisions for the indemnification of the Trustee and to
certain other conditions, the holders of a majority in aggregate principal
amount of the Outstanding Debt Securities of any series will have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee, or exercising any trust or power conferred on the
Trustee, with respect to the Debt Securities of that series. (Section 512)
 
  No holder of any series of Debt Securities will have any right to institute
any proceeding with respect to the Indenture or for any remedy thereunder,
unless such holder shall have previously given to the Trustee written notice
of a continuing Event of Default and unless the holders of at least 25% in
principal amount of the Outstanding Debt Securities of that series shall have
made written request, and offered reasonable indemnity, to the Trustee to
institute such proceeding as trustee, and the Trustee shall not have received
from the holders of a majority in aggregate principal amount of the
Outstanding Debt Securities of that series a direction inconsistent with such
request and shall have failed to institute such proceeding within 60 days.
(Section 507) However, such limitations do not apply to a suit instituted by a
holder of a Debt Security for enforcement of payment of the principal of and
premium, if any, or interest on such Debt Security on or after the respective
due dates expressed in such Debt Security. (Section 508)
 
  The Company is required to furnish to the Trustee annually a statement as to
the performance by the Company of certain of its obligations under the
Indenture and as to any default in such performance. (Section 1004)
 
MODIFICATION AND WAIVER
 
  Modifications and amendments of the Indenture may be made by the Company and
the Trustee without the consent of the holders of any of the Debt Securities
in order (i) to evidence the succession of another entity to the Company and
the assumption of the covenants and obligations of the Company under the Debt
Securities and the Indenture by such successor to the Company; (ii) to add to
the covenants of the Company for the benefit of the holders of all or any
series of Debt Securities or surrender any right or power conferred on the
Company by the Indenture; (iii) to add additional Events of Default with
respect to any series of Debt Securities; (iv) to add to or change any
provisions to such extent as necessary to facilitate the issuance of Debt
Securities in bearer form or to facilitate the issuance of Book Entry
Securities; (v) to add to, change or eliminate any provision
 
                                       9
<PAGE>
 
affecting only Debt Securities not yet issued; (vi) to secure the Debt
Securities; (vii) to establish the form or terms of Debt Securities of any
series; (viii) to evidence and provide for successor Trustees or to add or
change any provisions to such extent as necessary to provide for or facilitate
the appointment of a separate Trustee or Trustees for specific series of Debt
Securities; (ix) to permit payment in respect of Debt Securities in bearer
form in the United States to the extent allowed by law; (x) to cure any
ambiguity, to correct or supplement any mistaken or inconsistent provisions or
to make any other provisions with respect to matters or questions arising
under the Indenture, provided that any such action (other than in respect of a
mistaken provision) does not adversely affect in any material respect the
interests of any holder of Debt Securities of any series then outstanding.
(Section 901)
 
  Modifications and amendments of the Indenture also may be made by the
Company and the Trustee with the consent of the holders of not less than a
majority in aggregate principal amount of the Outstanding Debt Securities of
each series issued under the Indenture and affected by the modification or
amendments; provided, however, that no such modification or amendment may,
without the consent of the Holders of all Debt Securities affected thereby,
(i) change the Stated Maturity of the principal amount of, or any installment
of principal of or interest on, any Debt Security; (ii) reduce the principal
amount of, or the premium, if any, or (except as otherwise provided in the
Applicable Prospectus Supplement) interest on, any Debt Security (including in
the case of an Original Issue Discount Security the amount payable upon
acceleration of the maturity thereof); (iii) change the place or currency of
payment of principal of, premium, if any, or interest on any Debt Security;
(iv) impair the right to institute suit for the enforcement of any payment on
any Debt Security on or after the Stated Maturity thereof (or in the case of
redemption, on or after the Redemption Date); or (v) reduce the percentage in
principal amount of Outstanding Debt Securities of any series, the consent of
whose holders is required for modification or amendment of the Indenture or
for waiver of compliance with certain provisions of the Indenture or for
waiver of certain defaults. (Section 902)
 
  The holders of at least a majority in aggregate principal amount of the
Outstanding Debt Securities of any series may, on behalf of all holders of
Debt Securities of that series, waive compliance by the Company with certain
restrictive provisions of the Indenture. (Section 1010) The holders of not
less than a majority in aggregate principal amount of the Outstanding Debt
Securities of any series may, on behalf of all holders of Debt Securities of
that series, waive any past default under the Indenture, except a default in
the payment of principal, premium or interest or in respect of a covenant or
provision of the Indenture that cannot be modified or amended without the
consent of the holder of each Outstanding Debt Security of such series
affected thereby. (Section 513)
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
  The Company may not consolidate with or merge with or into any other entity
or transfer or lease its assets substantially as an entirety to any entity,
unless (i) either the Company is the continuing corporation, or any successor
or purchaser is a corporation, partnership or trust organized under the laws
of the United States of America, any State thereof or the District of
Columbia, and any such successor or purchaser expressly assumes the Company's
obligations on the Debt Securities under a supplemental indenture, (ii)
immediately after giving effect to the transaction, no Event of Default, and
no event which, after notice or lapse of time or both, would become an Event
of Default, shall have occurred and be continuing, (iii) if properties or
assets of the Company become subject to a Mortgage not permitted by the
Indenture, the Company or such successor entity, as the case may be, takes
such steps as shall be necessary effectively to secure the Debt Securities
equally and ratably with (or prior to) all Debt secured thereby, and (iv) if a
supplemental indenture is to be executed in connection with such
consolidation, merger, transfer or lease, the Company has delivered to the
Trustee an Officers' Certificate and an Opinion of Counsel stating compliance
with these provisions. (Section 801)
 
DEFEASANCE OF OFFERED DEBT SECURITIES OR CERTAIN COVENANTS IN CERTAIN
CIRCUMSTANCES
 
 Defeasance and Discharge
 
  The Indenture provides that the terms of any series of Debt Securities may
provide that the Company, at the Company's option, will be discharged from any
and all obligations in respect of the Debt Securities of such series
 
                                      10
<PAGE>
 
(except for certain obligations to register the transfer or exchange of Debt
Securities of such series, to replace stolen, lost or mutilated Debt
Securities of such series, to maintain paying agencies and to hold moneys for
payment in trust) upon the deposit with the Trustee, in trust, of money and/or
U.S. Government Obligations which, through the payment of interest and
principal thereof in accordance with their terms, will provide money in an
amount sufficient to pay any installment of principal (and premium, if any)
and interest on, and any mandatory sinking fund payments in respect of, the
Debt Securities of such series on the stated maturity of such payments in
accordance with the terms of the Indenture and such Debt Securities. Such
discharge may only occur if, among other things, the Company has delivered to
the Trustee an opinion of counsel to the effect that the Company has received
from, or there has been published by, the United States Internal Revenue
Service a ruling, or there has been a change in tax law, in either case to the
effect that such discharge will not be deemed, or result in, a taxable event
with respect to holders of the Debt Securities of such series. (Sections 1302
and 1304)
 
 Defeasance of Certain Covenants
 
  The Indenture provides that the terms of any series of Debt Securities may
provide the Company with the option to omit to comply with certain restrictive
covenants described in this Prospectus under "--Certain Covenants of the
Company--Restrictions on Secured Debt", "--Certain Covenants of the Company--
Restrictions on Sales and Leasebacks" and "--Consolidation, Merger and Sale of
Assets". The Company, in order to exercise such option, will be required to
deposit with the Trustee money and/or U.S. Government Obligations which,
through the payment of interest and principal thereof in accordance with their
terms, will provide money in an amount sufficient to pay principal (and
premium, if any) and interest on, and any mandatory sinking fund payments in
respect of, the Debt Securities of such series on the stated maturity of such
payments in accordance with the terms of the Indenture and such Debt
Securities. The Company will also be required to deliver to the Trustee an
opinion of counsel to the effect that the deposit and related covenant
defeasance will not cause the holder of the Debt Securities of such series to
recognize income, gain or loss for federal income tax purposes. (Sections 1303
and 1304)
 
  In the event the Company exercises this option and the Debt Securities of
such series are declared due and payable because of the occurrence of any
Event of Default, the amount of money and U.S. Government Obligations on
deposit with the Trustee will be sufficient to pay amounts due on the Debt
Securities of such series at the time of their stated maturity but may not be
sufficient to pay amounts due on the Debt Securities of such series at the
time of the acceleration resulting from such Event of Default. However, the
Company shall remain liable for such payments.
 
  The Applicable Prospectus Supplement will state if any defeasance provision
will apply to the Offered Debt Securities.
 
CONCERNING THE TRUSTEE
 
  The Bank of New York, a New York banking corporation, is the Trustee under
the Indenture and is also trustee under several other indentures with the
Company. The Company maintains banking and other business relationships in the
ordinary course of business with The Bank of New York. Pursuant to the
provisions of the Trust Indenture Act, upon the occurrence of certain events,
The Bank of New York may be deemed to have a conflicting interest, by virtue
of its acting as the Trustee under the Indenture, the several other indentures
and its other business relationships with the Company, thereby requiring it to
resign and be replaced by a successor trustee under any or all of the
Indenture or the several other indentures.
 
  The Trustee may resign at any time or may be removed by the holders of at
least a majority in aggregate principal amount of the Outstanding Debt
Securities. If the Trustee resigns, is removed or becomes incapable of acting
as Trustee or if a vacancy occurs in the office of the Trustee for any cause,
a successor Trustee shall be appointed in accordance with the provisions of
the Indenture.

                             PLAN OF DISTRIBUTION
 
  Any of the Debt Securities being offered hereby may be sold in any one or
more of the following ways from time to time: (i) through agents; (ii) to or
through underwriters; (iii) through dealers; and (iv) directly by the Company
to purchasers.
 
  The distribution of the Debt Securities may be effected from time to time in
one or more transactions at a fixed price or prices, which may be changed, at
market prices prevailing at the time of sale, at prices related to such
prevailing market prices or at negotiated prices.
 
  Offers to purchase Debt Securities may be solicited by agents designated by
the Company from time to time. Any such agent involved in the offer or sale of
the Debt Securities in respect of which this Prospectus is delivered will be
named, and any commissions payable by the Company to such agent will be set
forth, in the Applicable Prospectus Supplement. Unless otherwise indicated in
such Prospectus Supplement, any such agent will be acting on a reasonable best
efforts basis for the period of its appointment. Any such agent may be deemed
to be an underwriter, as that term is defined in the Securities Act, of the
Debt Securities so offered and sold.
 
  If Debt Securities are sold by means of an underwritten offering, the
Company will execute an underwriting agreement with an underwriter or
underwriters at the time an agreement for such sale is reached, and the names
of the specific managing underwriter or underwriters, as well as any other
underwriters, the respective amounts underwritten and the terms of the
transaction, including commissions, discounts and any other compensation of
the underwriters and dealers, if any, will be set forth in the Applicable
Prospectus Supplement which will be used by the underwriters to make resales
of the Debt Securities in respect of which this Prospectus is being delivered
to the public. If underwriters are utilized in the sale of any Debt Securities
in respect of which this Prospectus is being delivered, such Debt Securities
will be acquired by the underwriters for their own account and may be resold
from time to time in one or more transactions, including negotiated
transactions, at fixed public offering prices or at varying prices determined
by the underwriters at the time of sale. Debt Securities may be offered to the
public either through underwriting syndicates represented by managing
underwriters or directly by one or more underwriters. If any underwriter or
underwriters are utilized in the sale of Debt Securities, unless otherwise
indicated in the Applicable Prospectus Supplement, the underwriting agreement
will provide that the obligations of the underwriters are subject to certain
conditions precedent and that the underwriters with respect to a sale of such
Debt Securities will be obligated to purchase all such Debt Securities if any
are purchased.
 
  If a dealer is utilized in the sale of the Debt Securities in respect of
which this Prospectus is delivered, the Company will sell such Debt Securities
to the dealer as principal. The dealer may then resell such Debt Securities to
the public at varying prices to be determined by such dealer at the time of
resale. Any such dealer may be deemed to be an underwriter, as such term is
defined in the Securities Act, of the Debt Securities so offered and sold. The
name of the dealer and the terms of the transaction will be set forth in the
Prospectus Supplement relating thereto.
 
  Offers to purchase Debt Securities may be solicited directly by the Company
and the sale thereof may be made by the Company directly to institutional
investors or others, who may be deemed to be underwriters within the meaning
of the Securities Act with respect to any resale thereof. The terms of any
such sales will be described in the Prospectus Supplement relating thereto.
 
  If so indicated in the Applicable Prospectus Supplement, the Company may
authorize agents and underwriters to solicit offers by certain institutions to
purchase Debt Securities from the Company at the public offering price set
forth in the Applicable Prospectus Supplement pursuant to delayed delivery
contracts providing for payment and delivery on the date or dates stated in
the Applicable Prospectus Supplement. Such delayed delivery contracts will be
subject to only those conditions set forth in the Applicable Prospectus
Supplement. A commission indicated in the Applicable Prospectus Supplement
will be paid to underwriters and agents soliciting purchases of Debt
Securities pursuant to delayed delivery contracts accepted by the Company.
