         OFFER TO EXCHANGE ITS RATING ADJUSTABLE SENIOR NOTES DUE 2016
        WHICH HAVE BEEN REGISTERED UNDER THE SECURITIES ACT FOR ANY AND
         ALL OF ITS OUTSTANDING RATING ADJUSTABLE SENIOR NOTES DUE 2016
                            ------------------------
 
    The Exchange Offer will expire at 5:00 p.m., New York City time on November
8, 1996, unless extended.
 
    Stone Container Corporation, a Delaware corporation (the "Company"), hereby
offers (the "Exchange Offer"), upon the terms and subject to the conditions set
forth in this Prospectus (the "Prospectus") and the accompanying Letter of
Transmittal (the "Letter of Transmittal"), to exchange $1,000 principal amount
of its new Rating Adjustable Senior Notes due 2016 (the "New Notes") for each
$1,000 principal amount of its outstanding Rating Adjustable Senior Notes due
2016 (the "Old Notes" and, together with the New Notes, the "Notes"), of which
$125,000,000 aggregate principal amount is outstanding. The form and terms of
the New Notes are the same as the form and terms of the Old Notes, except that
the New Notes will have been registered under the Securities Act of 1933, as
amended (the "Securities Act"). The New Notes will evidence the same debt as the
Old Notes (which they replace) and will be issued under, and entitled to
benefits of, the Indenture governing the Old Notes dated as of July 24, 1996, as
supplemented and amended by the First Supplemental Indenture dated as of July
24, 1996 (the "Indenture"). All references herein to the "Notes" shall be
references to the Old Notes and/or the New Notes, whichever was, is or will be
outstanding in the particular context. See "The Exchange Offer" and "Description
of Notes."
 
    The Company will accept for exchange any and all Old Notes validly tendered
and not withdrawn prior to 5:00 p.m., New York City time, on November 8, 1996,
unless extended by the Company in its sole discretion (the "Expiration Date").
Tenders of Old Notes may be withdrawn at any time prior to the Expiration Date.
The Exchange Offer is subject to certain customary conditions. See "The Exchange
Offer." Old Notes may be tendered only in integral multiples of $1,000 principal
amount.
 
    The Old Notes were sold on July 24, 1996 in a transaction exempt from
registration under the Securities Act. The New Notes are being offered to
satisfy certain obligations of the Company under the Registration Rights
Agreement relating to the Old Notes. See "The Exchange Offer -- Purpose and
Effect of the Exchange Offer." New Notes issued pursuant to the Exchange Offer
in exchange for the Old Notes may be offered for resale, resold or otherwise
transferred by the holders thereof (other than any holder which is an affiliate
of the Company within the meaning of Rule 405 under the Securities Act), without
compliance with the registration and prospectus delivery requirements of the
Securities Act, provided that such New Notes are acquired in the ordinary course
of such holders' business and such holders have no arrangement with any person
to participate in the distribution of such New Notes. Each broker-dealer that
receives New Notes for its own account pursuant to the Exchange Offer must
acknowledge that it will deliver a prospectus in connection with any resale of
such New Notes. The Letter of Transmittal states that by acknowledging and by
delivering a prospectus, a broker-dealer will not be deemed to admit that it is
an "underwriter" within the meaning of the Securities Act. See "The Exchange
Offer -- Purpose and Effect of the Exchange Offer" and "Plan of Distribution."
 
    The Notes constitute securities for which there is no established trading
market. Any Old Notes not tendered and accepted in the Exchange Offer will
remain outstanding. To the extent that any Old Notes are tendered and accepted
in the Exchange Offer, a holder's ability to sell untendered Old Notes could be
adversely affected. The New Notes have been approved for listing on the New York
Stock Exchange ("NYSE"). No assurance can be given as to the liquidity of the
trading market for either the Old Notes or the New Notes.
 
    Interest on the New Notes shall accrue from the last February 1 or August 1
(an "Interest Payment Date") on which interest was paid on the Old Notes so
surrendered, or, if no interest has been paid on such Old Notes, from July 24,
1996.

                                  THE COMPANY
 
    The Company is a major international pulp and paper company engaged
principally in the production and sale of paper, packaging products, and market
pulp. The Company believes that it is the world's largest producer of unbleached
containerboard and kraft paper and the world's largest converter of those
products into corrugated containers and paper bags and sacks. The Company also
believes that it is one of the world's largest paper companies in terms of
annual tonnage, having produced approximately 8.0 million and 7.9 million total
tons of paper and pulp in 1995 and 1994, respectively. The Company produced
approximately 5.0 million and 5.2 million tons of unbleached containerboard and
kraft paper in 1995 and 1994, respectively, which accounted for approximately
63% and 66% of its total tonnage produced for 1995 and 1994, respectively. The
Company had net sales of approximately $7.4 billion and $5.7 billion in 1995 and
1994, respectively, and had net income of $255.5 million in 1995 and a net loss
of $204.6 million in 1994. The Company owns or has an interest in 130

PAPERBOARD AND PAPER PACKAGING
 
    The Company believes that its integrated unbleached paperboard and paper
packaging business is the largest in the world with 16 mills and 149 converting
plants located throughout the United States and Canada, and in Europe, Australia
and China. The major products in this business are containerboard and corrugated
containers, which are primarily sold to a broad range of manufacturers of
consumable and durable goods; kraft paper and paper bags and sacks, which are
sold primarily to supermarket chains, retailers of consumer products and, in the
case of multiwall shipping sacks, to the agricultural, chemical and cement
industries; and boxboard and folding cartons, which are sold to manufacturers of
consumable goods and other box manufacturers. The unbleached packaging business
of the Company has an annual capacity of approximately 5.5 million tons and is
more than 80% integrated. In 1995, total sales for the paperboard and paper
packaging business of the Company were approximately $5.4 billion, or
approximately 74% of total consolidated sales.
 
MARKET PULP
 
    The Company believes it is a major market producer of market pulp in North
America. The Company owns and operates five market pulp mills in North America,
including the Celgar mill in Castlegar, British Columbia in which the Company
has a 45% interest (the "Celgar mill"). These mills have the capacity to produce
1.2 million tons of market pulp annually and produced 1.1 million tons in 1995
(including 45% of the production at the Celgar mill). In addition,
Stone-Consolidated owns and operates the Fort Frances, Ontario mill, which has
an annual capacity of approximately 130 thousand tons of market pulp. The
geographic diversity of the Company's mills enables the Company to offer its
customers a product mix of bleached northern and southern hardwood and bleached
northern softwood pulp. Market pulp is sold to manufacturers of paper products,
including fine papers, photographic papers, tissue and newsprint.

<TABLE>
<S>                                  <C>
REGISTRATION RIGHTS AGREEMENT......  The Old Notes were sold July 24, 1996 (the "Closing Date")
                                     in a transaction exempt from registration under the
                                     Securities Act. In connection therewith, the Company
                                     executed and delivered, for the benefit of the holders of
                                     the Old Notes, a Registration Rights Agreement dated July
                                     24, 1996 (the "Registration Rights Agreement"), which grants
                                     the holders of Old Notes certain exchange and registration
                                     rights. See "The Exchange Offer -- Termination of Certain
                                     Rights." The Exchange Offer is intended to satisfy certain
                                     of such rights, which terminate upon the Consummation (as
                                     defined) of the Exchange Offer. Therefore, the holders of
                                     New Notes will not be entitled to any exchange or
                                     registration rights with respect to the New Notes.
THE EXCHANGE OFFER.................  $1,000 principal amount of New Notes in exchange for each
                                     $1,000 principal amount of Old Notes. As of the date hereof,
                                     $125,000,000 aggregate principal amount of Old Notes is
                                     outstanding. The terms of the New Notes are substantially
                                     identical in all respects (including principal amount,
                                     interest rate and maturity) to the terms of the Old Notes
                                     for which they may be exchanged pursuant to the Exchange
                                     Offer, except that the New Notes will have been registered
                                     under the Securities Act and will not bear legends
                                     restricting their transfer. See "The Exchange Offer -- Terms
                                     of the Exchange Offer" and "The Exchange Offer -- Procedures
                                     for Tendering."
                                     Based on an interpretation by the staff of the Commission
                                     set forth in no-action letters issued to third parties, the
                                     Company believes that New Notes issued pursuant to the
                                     Exchange Offer in exchange for Old Notes may be offered for
                                     resale, resold and otherwise transferred by any holder or
                                     beneficial owner thereof (other than any such holder or
                                     beneficial owner which is an "affiliate" of the Company
                                     within the meaning of Rule 405 under the Securities Act or a
                                     "broker" or "dealer" registered under the Exchange Act)
                                     without compliance with the registration and prospectus
                                     delivery provisions of the Securities Act, provided that
                                     such New Notes are acquired in the ordinary course of such
                                     holder's or beneficial owner's business and that such holder

 DELIVERY OF NEW NOTES.............  Subject to satisfaction or waiver of the conditions of the
                                     Exchange Offer set forth under "The Exchange Offer --

UNITED STATES FEDERAL INCOME TAX
 CONSEQUENCES......................  An exchange of Old Notes for New Notes pursuant to the
                                     Exchange Offer should not be treated as a sale, exchange or
                                     other taxable event for United States federal income tax
                                     purposes because the New Notes should not be considered to
                                     differ materially in kind or extent from the Old Notes. As a
                                     result, no material federal income tax consequences should
                                     result from an exchange of Old Notes for New Notes pursuant
                                     to the Exchange Offer. For federal income tax purposes, a
                                     New Note received by a beneficial owner of an Old Note
                                     should be treated as a continuation of the Old Note in the
                                     hands of such owner. See "United States Federal Income Tax
                                     Consequences."
EFFECT ON HOLDERS OF THE OLD
 NOTES.............................  As a result of the making of, and upon acceptance for
                                     exchange of all validly tendered Old Notes pursuant to the
                                     terms of, the Exchange Offer, the Company will have
                                     fulfilled certain of its obligations contained in the
                                     Registration Rights Agreement and, accordingly, there will
                                     be no increase in the interest rate on the Old Notes
                                     pursuant to the applicable terms of the Registration Rights
                                     Agreement. Holders of the Old Notes who do not tender their
                                     Old Notes will be entitled to all the rights and limitations
                                     applicable thereto under the Indenture and the Registration
                                     Rights Agreement, except for any rights under the Indenture
                                     or the Registration Rights Agreement which by their terms
                                     terminate or cease to have further effect as a result of the
                                     making of, and the acceptance for exchange of all validly
                                     tendered Old Notes pursuant to, the Exchange Offer. All
                                     untendered Old Notes will continue to be subject to the
                                     restrictions on transfer provided for in the Old Notes and
                                     in the Indenture. The Registration Rights Agreement provides
                                     that if a holder of $1,000,000 aggregate principal amount or

                                     such holder was prohibited by law or Commission policy from
                                     participating in the Exchange Offer or (B) such holder may
                                     not resell the Exchange Notes acquired by it in the Exchange

                                     under the Securities Act. To the extent that Old Notes are
                                     tendered and accepted in the Exchange Offer, the trading
                                     market for untendered Old Notes could be adversely affected.

                                  RISK FACTORS
 
    PROSPECTIVE INVESTORS SHOULD CAREFULLY CONSIDER THE RISK FACTORS SET FORTH
BELOW AND OTHER INFORMATION INCLUDED ELSEWHERE OR INCORPORATED BY REFERENCE IN
THIS PROSPECTUS.
 
ABILITY OF THE COMPANY TO MAKE PAYMENTS
 
    The Company's ability to make payments under the Notes depends upon the
Company's future performance, which is subject to many factors, several of which
are beyond the Company's control. While the Company expects to have funds
available sufficient to pay debt service with respect to the Notes when due, no
representation or assurance can be made that revenues will be realized by the
Company in amounts sufficient to make such payments. The future financial
condition of the Company could be adversely affected by, among other things,
demand for and sale prices of paper products, cost of raw materials and other
production costs, competition, general economic developments affecting the
Company, future access to credit markets to finance operations and refinance
existing indebtedness, environmental and other regulations and other
developments that cannot now be foreseen. Such factors may materially and
adversely affect the ability of the Company to make payments with respect to the
Notes.
 
SIGNIFICANT LEVERAGE AND DEBT SERVICE REQUIREMENTS
 
    The Company has significant payment obligations under the Notes, in addition
to the Company's other indebtedness. As a result of indebtedness incurred by the
Company to finance the acquisition of Stone Container (Canada) Inc. (formerly
known as Consolidated-Bathurst, Inc.) in 1989 and indebtedness incurred to fund
operating losses incurred during the cyclical downturn from 1991-1994, the
Company is highly leveraged. The Company's total long-term indebtedness and
long-term debt to total capitalization ratio were 3.9 billion and 73.0%,
respectively, at June 30, 1996, which does not include the Notes or the SCFC
Notes (as defined below). Capitalization, for purposes of these ratios, includes
long-term debt (which at June 30, 1996 includes $252.9 million of indebtedness
of certain consolidated affiliates that is non-recourse to the Company),
deferred income taxes, minority interest and stockholders' equity.
 
    Because it is highly leveraged, the Company will continue to require access
to significant funds in order to service its debt, including significant
amortization payments due beginning in 1997 and continuing thereafter. The
amounts of long-term debt (excluding capitalized lease obligations) outstanding
at June 30, 1996 maturing through 2001 and thereafter are as follows:

(3) Does not include the Notes or the Stone Container Finance Company of Canada
    11 1/2% Senior Notes due 2006 (the "SCFC Notes"), issued August 16, 1996,
    unconditionally guaranteed on a senior basis by the Company and of which
    $200 million is outstanding as of August 31, 1996, and does not give effect
    to the application of the proceeds therefrom.
 
    In order to meet its amortization obligations, the Company will be required
to raise sufficient funds from operations and/or other sources and/or refinance
or restructure maturing indebtedness. No assurance can be given that financial
resources available to the Company will be sufficient to meet its debt service
obligations, including those on the Notes. If the Company is unable to generate
sufficient cash flow to meet its debt obligations, it may be required to pursue
other alternatives, including cost reductions, sales of assets, deferral of
certain capital expenditures and obtaining additional sources of funds.
 
    The Company is a party to, and in certain instances is subject to the terms
and provisions of, various significant financial agreements, mortgages,
indentures, instruments, facilities, guarantees and other arrangements
(collectively, "Financial Obligations"). Certain of the Financial Obligations
evidence indebtedness that is secured by a substantial portion of the assets of
the Company. If such assets were utilized to support payment of or retire a
significant portion of the indebtedness evidenced by the Financial Obligations,
a substantial portion of the assets of the Company would be depleted. As of June
30, 1996, $1.8 billion or 45% of the Company's total indebtedness was secured by
pledges of, security interests in and mortgages of the Company's assets.
 
CYCLICALITY, OPERATING LOSSES AND PRICING
 
    The markets for paper, packaging products and market pulp sold by the
Company are highly sensitive to changes in capacity of the paper industry and
cyclical changes in the economy, all of which can significantly impact demand
for and selling prices of the Company's products and thereby the Company's
profitability. The Company's product lines generally experienced declining
product prices from 1990 through the third quarter of 1993, which contributed to
the net losses incurred by the Company in each of the four years from 1991
through 1994. Improved economic conditions and demand/supply characteristics in
the paper industry enabled the Company to implement price increases for most of
its products beginning in October 1993. Pricing continued to improve in 1994 and
1995 through the third quarter of 1995. However, due to imbalance in the
demand/supply relationship for containerboard, corrugated containers and market
pulp during the third and fourth quarters of 1995, industry containerboard and
market pulp inventories rose significantly during that time. As a result of that
imbalance, containerboard and market pulp prices began declining during the
fourth quarter of 1995 with such declines continuing through the second quarter
of 1996, during which quarter the Company experienced a net loss of $21.1
million. In addition, prices for newsprint, which is the primary product of
Stone-Consolidated have also declined during the first and second quarters of
1996. The Company took market-related downtime at certain of its mills for
inventory balancing purposes in the last half of 1995 and in the first half of
1996. No assurance can be given that additional market-related downtime will not
be taken during the remainder of 1996.
 
    As a consequence of these changes in the demand/supply characteristics for
the Company's products and recent decreases in the prices for those products,
operating results will be significantly reduced until demand increases as a
result of improvement in economic conditions. The Company's highly leveraged
capital structure makes it particularly vulnerable during industry down cycles,
which could adversely affect its financial flexibility and, as a result,
adversely affect its ability to service its debt obligations, including payment
with respect to the Notes.
 
FIBER SUPPLY AND PRICING
 
    Wood fiber and recycled fiber, the principal raw materials used in the
manufacture of the Company's products, are purchased in highly competitive,
price sensitive markets. These raw materials have historically exhibited price
and demand cyclicality. The Company purchases or cuts a variety of species of
timber from which the Company utilizes wood fiber. The supply and price of wood
fiber in particular is dependent upon a variety of factors over which the
Company has no control, including environmental and conservation regulations,
natural disasters, such as forest fires and hurricanes, and weather. In
 
                                       13
<PAGE>
addition, an increase in demand for the Company's and the paper industry's
products would result in greater demand for raw materials, and, coupled with
decreased sources of supply, could translate into higher raw material prices,
including a significant increase in the costs of recycled fiber.
 
    The cost of recycled fiber is highly volatile. Over the last 18 months,
prices of old corrugated containers ("OCC") had risen to levels as high as $250
per ton and dropped to levels as low as $25 per ton. Currently the price of OCC
is $30-$90 per ton. It is possible that the increase in capacity of mills
utilizing recycled fiber may cause the price of OCC to rise. In addition,
increased utilization of recycled fiber may cause decreased sources of supply.
While the Company has not experienced any significant difficulty in obtaining
wood fiber and recycled fiber for its mills, there can be no assurance that this
will continue to be the case for any or all of its mills. See "Business -- Fiber
Supply."
 
COMPETITION
 
    The paper, packaging products and market pulp produced by the Company are
sold in highly competitive markets. The Company faces competition from a variety
of sources, including other companies attempting to expand production through
the use of greater recycled fiber content products. The Company competes
directly with a number of such other producers, some of which have financial and
other resources greater than those of the Company. See "Business -- Markets and
Competition."
 
CREDIT AGREEMENT RESTRICTIONS
 
    Borrowings under the Credit Agreement are secured by a substantial portion
of the assets of the Company. The Credit Agreement contains covenants that
include, among other things, the maintenance of certain financial tests and
ratios consisting of an indebtedness ratio and a minimum interest coverage
ratio. The Credit Agreement also contains certain restrictions and limitations,
including those on capital expenditures, changes in control, payment of
dividends, sales of assets, lease payments, investments, additional
indebtedness, liens, repurchases or prepayment of certain indebtedness,
guarantees of indebtedness, mergers and purchases of stock and assets. The
Credit Agreement also contains cross-default provisions to indebtedness of $10
million or more of the Company and certain subsidiaries. Additionally, the term
loan portion of the Credit Agreement provides for mandatory prepayments from
sales of certain assets, certain debt financings and a percentage of Excess Cash
Flow (as defined in the Credit Agreement).
 
    The Company is required to maintain compliance with the prescribed financial
ratio tests, including indebtedness ratio and interest coverage ratio tests, and
other requirements contained in the Credit Agreement. Failure to maintain
compliance with such financial ratio tests or other requirements under the
Credit Agreement, in the absence of a waiver or amendment, would result in an
event of default and could lead to acceleration of the obligations under the
Credit Agreement. If waivers or amendments are requested by the Company, there
can be no assurance that the Company's bank lenders will grant such requests,
which, in turn, at the election of the holders of certain of the Company's other
indebtedness, could accelerate such other indebtedness. The failure to obtain
any such waivers or amendments would reduce the Company's flexibility to respond
to adverse industry conditions and could have a material adverse effect on the
Company. The Company is currently seeking an amendment with respect to certain
covenants under the Credit Agreement for periods including the fourth quarter of
1996 and the first three quarters of 1997. See "Credit Agreement -- Covenants."
 
LEGAL AND ADMINISTRATIVE PROCEEDINGS
 
    The Company is involved in various contract disputes, legal and
administrative proceedings and investigations of various types. Although any
litigation, proceeding or investigation has an element of uncertainty, the
Company believes that the outcome of any proceeding, lawsuit or claim that is
pending or threatened, or all of them combined, other than those described
specifically herein under "Business -- Legal Proceedings," would not have a
material adverse effect on its consolidated financial position, results of
operations or liquidity.
 
                                       14
<PAGE>
ENVIRONMENTAL MATTERS
 
    The Company's operations are subject to extensive environmental regulation
by federal, state and local authorities in the United States and regulatory
authorities with jurisdiction over its foreign operations. The Company has in
the past made significant capital expenditures to comply with water, air and
solid and hazardous waste regulations and expects to make significant
expenditures in the future. Capital expenditures for environmental control
equipment and facilities were approximately $36 million in 1995 and the Company
anticipates that 1996 and 1997 environmental capital expenditures will
approximate $61 million and $16 million, respectively (exclusive of any
potential expenditures which may be required if the proposed "cluster rules"
described below are adopted). Although capital expenditures for environmental
control equipment and facilities and compliance costs in future years will
depend on legislative and technological developments which cannot be predicted
at this time, the Company anticipates that these costs will increase when final
"cluster rules", as described below, are adopted and as other environmental
regulations are imposed on the Company. In addition to capital expenditures for
environmental control equipment and facilities, other expenditures incurred to
maintain environmental regulatory compliance (including any remediation)
represent ongoing costs to the Company.
 
    In December 1993, the U.S. Environmental Protection Agency (the "EPA")
issued a proposed rule affecting the pulp and paper industry. These proposed
regulations, informally known as the "cluster rules," would make more stringent
requirements for discharge of wastewaters under the Clean Water Act and would
impose new requirements on air emissions under the Clean Air Act. Pulp and paper
manufacturers (including the Company) have submitted extensive comments to the
EPA on the proposed regulations in support of the position that requirements
under the proposed regulations are unnecessarily complex, burdensome and
environmentally unjustified. The EPA reopened the comment period on the proposed
regulations to allow review and comment on new data that the industry submitted
to the agency on the industry's air toxic emissions. It cannot be predicted at
this time whether the EPA will modify the requirements in the final regulations
which are scheduled to be issued in 1996, with compliance required within three
years from such date. The Company is considering and evaluating the potential
impact of the rules, as proposed, on its operations and capital expenditures
over the next several years. Estimates, based on the currently proposed
regulations, indicate that the Company could be required to make capital
expenditures of $350 - $450 million during the period of 1996 through 1998 in
order to meet the requirements of the regulations, although it is possible this
range could decrease upon finalization of the rules. In addition, annual
operating expenses would increase by as much as $20 million beginning in 1998.
The ultimate financial impact of the regulations cannot be accurately estimated
at this time but will be affected by several factors, including the actual
requirements imposed under the final rules, advancements in control process
technologies, possible reconfiguration of mills and inflation.
 
    The Company is from time to time subject to litigation and governmental
proceedings regarding environmental matters in which injunctive and/or monetary
relief is sought. The Company has been named as a potentially responsible party
("PRP") at a number of sites which are the subject of remedial activity under
the federal Comprehensive Environmental Response, Compensation and Liability Act
of 1980 ("CERCLA" or "Superfund") or comparable state laws. Although the Company
is subject to joint and several liability imposed under Superfund, at most of
the multi-PRP sites there are organized groups of PRPs and costs are being
shared among PRPs. See "Business -- Legal Proceedings."
 
    Future environmental regulations, including the final "cluster rules," may
have an unpredictable adverse effect on the Company's operations and earnings,
but they are not expected to adversely affect the Company's competitive
position.
 
RANKING OF THE NOTES
 
    The Notes will be senior unsecured obligations of the Company and will rank
PARI PASSU in right of payment with all existing and future Senior Indebtedness
of the Company, including the indebtedness under the Credit Agreement and the
Company's $239 million outstanding principal amount of 11 7/8% Senior Notes due
1998, $150 million outstanding principal amount of 12 5/8% Senior Notes due
1998,
 
                                       15
<PAGE>
$574 million outstanding principal amount of 9 7/8% Senior Notes due 2001, $497
million outstanding principal amount of 10 3/4% First Mortgage Notes due 2002
(the "First Mortgage Notes"), $199 million outstanding principal amount of
11 1/2% Senior Notes due 2004 and the Company's guaranty of $200 million
outstanding principal amount of SCFC Notes. As of June 30, 1996, the total
amount of outstanding Senior Indebtedness of the Company was approximately $3.7
billion (which amount includes existing revolving credit commitments of the
Company but does not reflect the issuance of the Notes or the SCFC Notes, and
does not give effect to the application of the proceeds therefrom).
 
    A substantial portion of the Company's assets currently secure borrowings
outstanding under the Credit Agreement. At June 30, 1996, the Company had $767
million outstanding under the Credit Agreement. The Company's First Mortgage
Notes, of which there was $497 million outstanding as of June 30, 1996, are
secured by four of the Company's mills and related assets. In the event of the
Company's insolvency or liquidation, the claims of the lenders under the Credit
Agreement would have to be satisfied out of the collateral securing borrowings
under the Credit Agreement before any such assets would be available to pay
claims of holders of the Notes. Similarly, the holders of the First Mortgage
Notes would have to be satisfied out of the collateral under the indenture and
related security documents with respect to the First Mortgage Note before any
such assets would be available to pay claims of holders of the Notes. If the
lenders under the Credit Agreement and/or the First Mortgage Note trustee under
the First Mortgage Note indenture and the related security documents should
foreclose on their respective collateral, no assurance can be given that there
will be sufficient assets available in the Company to pay amounts due under the
Notes. In addition, obligations of the Company's Subsidiaries, including trade
payables of any such Subsidiaries, will represent prior claims with respect to
the assets and earnings of such Subsidiaries.
 
FUTURE ACCESS TO THE CAPITAL MARKETS
 
    Giving effect to the Offering, the Company will have sold securities on a
number of occasions in the last two years for total proceeds in excess of $2.3
billion. The recent issuance of a substantial amount of securities may make it
difficult, at least in the near future, for the Company to access the capital
markets for further financings and therefore may limit the Company's sources of
future liquidity.
 
CHANGE OF CONTROL
 
    Upon the occurrence of a Change of Control, and subject to the prior rights
of certain lenders under certain specified bank debt, the Company is required to
offer to purchase each holder's Notes at a purchase price equal to 101% of the
aggregate principal amount thereof, plus accrued and unpaid interest, if any, to
the date of purchase. Such Change of Control provisions in and of themselves may
not afford holders of the Notes protection in the event of a highly leveraged
transaction, reorganization, restructuring, merger or similar transaction
involving the Company that may adversely affect such holders if such transaction
is not the type of transaction included within the definition of Change of
Control. See "Description of Notes -- Change of Control." There can be no
assurance that the Company would have sufficient funds to pay the required
purchase price for all Notes tendered by the holders thereof in the event of a
Change of Control. Neither the Board of Directors of the Company nor the Trustee
under the Indenture (as defined) relating to the Notes may waive the Change of
Control provisions.
 
ABSENCE OF PUBLIC MARKET FOR THE NOTES
 
    The New Notes are being offered to the holders of the Old Notes. The Old
Notes were offered and sold to a small number of institutional investors and are
eligible for trading in the Private Offerings, Resale and Trading through
Automatic Linkages ("PORTAL") Market. Prior to the Exchange Offer, there has
been no market for the New Notes. The New Notes have been approved for listing
on the NYSE. Future trading prices of the New Notes will depend upon many
factors including prevailing interest rates, the Company's operating results and
the market for similar securities.

<PAGE>
                               THE EXCHANGE OFFER
 
PURPOSE AND EFFECT OF THE EXCHANGE OFFER
 
    As a condition to the obligations of the Initial Purchasers under the
Purchase Agreement relating to the offering of the Old Notes (the "Purchase
Agreement"), the Company and the Initial Purchasers entered into the
Registration Rights Agreement on July 24, 1996. Pursuant to the Registration
Rights Agreement the Company agreed (i) to file with the Commission a
registration statement under the Securities Act with respect to the New Notes
within 60 days after the Closing Date, (ii) to use its best efforts to cause
such registration statement to become effective under the Securities Act as soon
as practicable, but in no event later than 120 days after the Closing Date, and
(iii) unless the Exchange Offer would not be permitted by applicable law or
Commission policy, the Company will commence the Exchange Offer and use its best
efforts to issue on or prior to 60 business days after the date on which the
Exchange Offer Registration Statement was declared effective by the Commission,
New Notes in exchange for all Old Notes tendered prior thereto in the Exchange
Offer. A copy of the Registration Rights Agreement has been filed as an exhibit
to the Registration Statement of which this Prospectus is a part. This
Registration Statement is intended to satisfy certain of the Company's
obligations under the Registration Rights Agreement and the Purchase Agreement.
 
    Following the Consummation (as defined under "-- Termination of Certain
Rights") of the Exchange Offer, except as set forth below, holders of Old Notes
not tendered will not have any further registration rights or rights to receive
certain specified liquidated damages and the Old Notes will continue to be
subject to certain restrictions on transfer. See "-- Holders Prohibited from
Participating in Exchange Offer," "-- Termination of Certain Rights" and "--
Consequences of Failure to Exchange." Accordingly, the liquidity of the market
for the Old Notes could be adversely affected.
 
TERMS OF THE EXCHANGE OFFER
 
    Upon the terms and subject to the conditions set forth in this Prospectus
and in the Letter of Transmittal, the Company will accept any and all Old Notes
validly tendered and not withdrawn prior to the Expiration Date. The Company
will issue $1,000 principal amount of New Notes in exchange for each $1,000
principal amount of outstanding Old Notes accepted in the Exchange Offer.
Holders may tender some or all of their Old Notes pursuant to the Exchange
Offer. However, Old Notes may be tendered only in integral multiples of $1,000
principal amount.
 
    The form and terms of the New Notes are the same in all material respects as
the form and terms of the Old Notes except that (i) the New Notes will have been
registered under the Securities Act and hence will not bear legends restricting
their transfer pursuant to the Securities Act and (ii) holders of New Notes will
not be entitled to certain rights of holders of Old Notes under the Registration
Rights Agreement which will terminate upon the Consummation of the Exchange
Offer. The New Notes will evidence the same debt as the Old Notes (which they
replace) and will be issued under, and be entitled to the benefits of, the
Indenture governing the Old Notes.
 
    As of the date of this Prospectus, $125,000,000 aggregate principal amount
of the Old Notes was outstanding and registered in the name of Cede & Co., as
nominee for The Depository Trust Company (the "Depository" or "DTC"). Only a
registered holder of Old Notes (or such holder's legal representative or
attorney-in-fact) as reflected on the records of the Trustee under the Indenture
may participate in the Exchange Offer. There will be no fixed record date for
determining registered holders of Old Notes entitled to participate in the
Exchange Offer.
 
    Holders of Old Notes do not have any appraisal or dissenters' rights under
the Delaware General Corporation Law or the Indenture in connection with the
Exchange Offer. The Company intends to conduct the Exchange Offer in accordance
with the applicable requirements of the Exchange Act and the rules and
regulations of the Commission thereunder.
 
                                       17
<PAGE>
    The Company shall be deemed to have accepted validly tendered Old Notes
when, as and if the Company has given oral or written notice thereof to the
Exchange Agent. The Exchange Agent will act as agent for the tendering holders
of Old Notes for the purposes of receiving the New Notes from the Company.
 
    If any tendered Old Notes are not accepted for exchange because of an
invalid tender, the occurrence of certain other events set forth herein or
otherwise, certificates for any such unaccepted Old Notes will be returned (or,
in the case of Old Notes tendered by book-entry transfer through DTC, will be
credited to an account maintained with DTC), without expense, to the tendering
holder thereof as promptly as practicable after the Expiration Date. See "--
Procedures for Tendering."
 
    Holders who tender Old Notes in the Exchange Offer will not be required to
pay brokerage commissions or fees or, subject to the instructions in the Letter
of Transmittal, transfer taxes with respect to the exchange of Old Notes
pursuant to the Exchange Offer. The Company will pay all charges and expenses,
other than certain applicable taxes, in connection with the Exchange Offer. See
"-- Fees and Expenses."
 
HOLDERS PROHIBITED FROM PARTICIPATING IN EXCHANGE OFFER
 
    The Registration Rights Agreement provides that if a holder of $1,000,000
aggregate principal amount or more of Notes notifies the Company within 20
business days following Consummation of the Exchange Offer that (A) such holder
was prohibited by law or Commission policy from participating in the Exchange
Offer or (B) such holder may not resell the New Notes acquired by it in the
Exchange Offer to the public without delivering a prospectus and this Prospectus
is not appropriate or available for such resales by such holder or (C) such
holder is a broker or dealer registered under the Exchange Act and holds Notes
acquired directly from the Company or one of its affiliates, then the Company is
required to file the Shelf Registration Statement. The Registration Rights
Agreement also provides that the Company will use its best efforts to keep the
Shelf Registration Statement continuously effective, supplemented and amended to
the extent necessary to ensure that it is available for sales of Old Notes by
the holders thereof entitled to the benefit of the Registration Rights
Agreement, for a period expiring on the earlier of (i) the date that all holders
of Old Notes who have properly requested registration have sold such securities
pursuant to the Shelf Registration Statement and (ii) July 24, 1999.
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
    The term "Expiration Date" shall mean 5:00 p.m., New York City time, on
November 8, 1996, unless the Company, in its sole discretion, extends the
Exchange Offer, in which case the term "Expiration Date" shall mean the latest
date and time to which the Exchange Offer is extended.
 
    In order to extend the Exchange Offer, the Company will notify the Exchange
Agent of any extension by oral or written notice and will make a public
announcement thereof, each prior to 9:00 a.m., New York City time, on the next
business day after the previously scheduled Expiration Date.
 
    The Company reserves the right, in its sole discretion, (i) to delay
accepting any Old Notes, (ii) to extend the Exchange Offer, (iii) if any of the
conditions set forth below under "-- Conditions of the Exchange Offer" shall not
have been satisfied, to terminate the Exchange Offer by giving oral or written
notice of such delay, extension or termination to the Exchange Agent, or (iv) to
amend the terms of the Exchange Offer in any manner. Any such delay in
acceptance, extension, termination or amendment will be followed as promptly as
practicable by a public announcement thereof. If the Exchange Offer is amended
in a manner determined by the Company to constitute a material change, the
Company will promptly disclose such amendments by means of a prospectus
supplement that will be distributed to the registered holders of Old Notes, and
the Company will extend the Exchange Offer for a period of five to ten business
days, depending upon the significance of the amendment and the manner of
disclosure to the registered holders, if the Exchange Offer would otherwise
expire during such five to ten business day period.
 
                                       18
<PAGE>
    Without limiting the manner in which the Company may choose to make public
announcement of any delay, extension, termination or amendment of the Exchange
Offer, the Company shall not have an obligation to publish, advertise, or
otherwise communicate any such public announcement, other than by making a
timely release to the Dow Jones News Service.
 
PROCEDURES FOR TENDERING
 
    Only a registered holder of Old Notes may tender such Old Notes in the
Exchange Offer. To tender in the Exchange Offer, a holder must complete, sign
and date the Letter of Transmittal, or a facsimile thereof, have the signatures
thereon guaranteed if required by the Letter of Transmittal, and mail or
otherwise deliver such Letter of Transmittal or such facsimile, together with
the Old Notes and any other required documents, to the Exchange Agent at the
address set forth below under "-- Exchange Agent" for receipt prior to the
Expiration Date; provided, however, that in lieu of the foregoing, a holder may
either (i) tender the Old Notes pursuant to the procedure for book-entry tender
set forth below, or (ii) comply with the guaranteed delivery procedure set forth
below.
 
    The tender by a holder will constitute an agreement between such holder and
the Company in accordance with the terms and subject to the conditions set forth
herein and in the Letter of Transmittal.
 
    THE METHOD OF DELIVERY OF OLD NOTES AND THE LETTER OF TRANSMITTAL AND ALL
OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK OF
THE HOLDER. INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS USE AN
OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL CASES, SUFFICIENT TIME SHOULD BE
ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE AGENT BEFORE THE EXPIRATION DATE. NO
LETTER OF TRANSMITTAL OR OLD NOTES SHOULD BE SENT TO THE COMPANY. HOLDERS MAY
REQUEST THEIR RESPECTIVE BROKERS, DEALERS, COMMERCIAL BANKS, TRUST COMPANIES OR
NOMINEES TO EFFECT THE ABOVE TRANSACTION FOR SUCH HOLDERS.
 
    Any beneficial owner whose Old Notes are registered in the name of a broker,
dealer, commercial bank, trust company or other nominee and who wishes to tender
should contact the registered holder promptly and instruct such registered
holder to tender on such beneficial owner's behalf. See "Instruction to
Registered Holder from Beneficial Owner" included with the Letter of
Transmittal.
 
    Signatures on a Letter of Transmittal or a notice of withdrawal, as the case
may be, must be guaranteed by an Eligible Institution (as defined) unless the
Old Notes tendered pursuant thereto are tendered (i) by a registered holder who
has not completed the box entitled "Special Delivery Instructions" on the Letter
of Transmittal, or (ii) for the account of an Eligible Institution. In the event
that signatures on a Letter of Transmittal or a notice of withdrawal, as the
case may be, are required to be guaranteed, such guarantee must be by a member
of one of the following signature guarantee programs: the Securities Transfer
Agents Medallion Program (STAMP), the New York Stock Exchange Medallion
Signature Program (MSP) and the Stock Exchange Medallion Program (SEMP) (an
"Eligible Institution").
 
    If the Letter of Transmittal is signed by a person other than the registered
holder of any Old Notes listed therein, such Old Notes must be endorsed or
accompanied by a properly completed bond power, signed by such registered holder
as such registered holder's name appears on such Old Notes.
 
    If the Letter of Transmittal or any Old Notes or bond powers are signed by
trustees, executors, administrators, guardians, attorneys-in-fact, officers of
corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and evidence satisfactory to the
Company of their authority to so act must be submitted with the Letter of
Transmittal.
 
    All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of tendered Old Notes will be determined by
the Company, in its sole discretion, which determination will be final and
binding. The Company reserves the absolute right to reject any and all Old Notes
not properly tendered or any Old Notes the Company's acceptance of which would,
in the opinion of counsel for the Company, be unlawful. The Company also
reserves the right to waive any defects, irregularities or conditions of tender
as to particular Old Notes. The Company's interpretation of the
 
                                       19
<PAGE>
terms and conditions of the Exchange Offer (including the instructions in the
Letter of Transmittal) will be final and binding on all parties. Unless waived,
any defects or irregularities in connection with tenders of Old Notes must be
cured within such time as the Company shall determine. Although the Company
intends to notify holders of defects or irregularities with respect to tenders
of Old Notes, neither the Company, the Exchange Agent nor any other person shall
incur any liability for failure to give such notification. Tenders of Old Notes
will not be deemed to have been made until such defects or irregularities have
been cured or waived. Any Old Notes received by the Exchange Agent that are not
validly tendered and as to which the defects or irregularities have not been
cured or waived will be returned by the Exchange Agent to the tendering holders,
unless otherwise provided in the Letter of Transmittal, as soon as practicable
following the Expiration Date.
 
    By tendering, each registered holder will represent to the Company that,
among other things, (i) the New Notes to be acquired by the holder and any
beneficial owner(s) of Old Notes ("Beneficial Owner(s)") in connection with the
Exchange Offer are being acquired by the holder and any Beneficial Owner(s) in
the ordinary course of business of the holder and any Beneficial Owner(s), (ii)
the holder and each Beneficial Owner are not engaging in, do not intend to
engage in, and have no arrangement or understanding with any person to
participate, in the distribution of the New Notes, (iii) the holder and each
Beneficial Owner acknowledge and agree that any person participating in the
Exchange Offer for the purpose of distributing the New Notes must comply with
the registration and prospectus delivery requirements of the Securities Act in
connection with a secondary resale transaction of the New Notes acquired by such
person and cannot rely on the position of the Staff of the Commission set forth
in no-action letters that are discussed under "Plan of Distribution", (iv) the
holder and each Beneficial Owner understands that a secondary resale transaction
described in clause (iii) above should be covered by an effective registration
statement containing the selling securityholder information required by Item 507
or 508, as applicable, of Regulation S-K of the Commission, and (v) neither the
holder nor any Beneficial Owner(s) is an "affiliate," as defined under Rule 405
of the Securities Act, of the Company except as otherwise disclosed to the
Company in writing.
 
EXCHANGING BOOK-ENTRY OLD NOTES
 
    The Exchange Agent and DTC have confirmed that any financial institution
that has an account with DTC (a "Participant") may utilize DTC's Automated
Tender Offer Program ("ATOP") to tender Old Notes.
 
    The Exchange Agent will request that DTC establish an account with respect
to the Old Notes for purposes of the Exchange Offer within two business days
after the date of the Exchange Offer. Any Participant may make book-entry
delivery of Old Notes by causing DTC to transfer such Old Notes into such
Exchange Agent's account in accordance with DTC's ATOP procedures for transfer.
However, the exchange for the Old Notes so tendered will only be made after
timely confirmation (a "Book-Entry Confirmation") of such book-entry transfer of
Old Notes into the Exchange Agent's account, and timely receipt by the Exchange
Agent of an Agent's Message (as defined) and any other documents required by the
Letter of Transmittal. The term "Agent's Message" means a message, transmitted
by DTC and received by the Exchange Agent and forming part of a Book-Entry
Confirmation, which states that DTC has received an express acknowledgment from
a Participant tendering Old Notes which are the subject of such Book-Entry
Confirmation that such Participant has received and agrees to be bound by the
terms of the Letter of Transmittal, and that the Company may enforce such
agreement against such Participant.
 
    The method of delivery of Old Notes is at the option and risk of the
tendering holder and, except as otherwise provided in the Letter of Transmittal,
the delivery will be deemed to be made only when actually received by the
Exchange Agent.
 
GUARANTEED DELIVERY PROCEDURES
 
    Holders who wish to tender their Old Notes and (i) whose Old Notes are not
immediately available, or (ii) who cannot deliver their Old Notes, the Letter of
Transmittal or any other required documents to the Exchange Agent prior to the
Expiration Date or (iii) who cannot comply with the procedure for book-entry
tender on a timely basis, may effect a tender if:
 
                                       20
<PAGE>
        (a) The tender is made through an Eligible Institution;
 
        (b) Prior to the Expiration Date, the Exchange Agent receives from such
    Eligible Institution a properly completed and duly executed Notice of
    Guaranteed Delivery (by facsimile transmission, mail or hand delivery)
    setting forth the name and address of the holder, the certificate number(s)
    of such Old Notes and the principal amount of the Old Notes being tendered,
    stating that the tender is being made thereby and guaranteeing that, within
    five business days after the Expiration Date, the Letter of Transmittal (or
    facsimile thereof) together with the certificate(s) representing the Old
    Notes and any other documents required by the Letter of Transmittal will be
    deposited by the Eligible Institution with the Exchange Agent; and
 
        (c) Such properly completed and executed Letter of Transmittal (or
    facsimile thereof), as well as the certificate (s) representing all tendered
    Old Notes in proper form for transfer and all other documents required by
    the Letter of Transmittal, are received by the Exchange Agent within five
    business days after the Expiration Date.
 
    Upon request to the Exchange Agent, a Notice of Guaranteed Delivery will be
sent to holders who wish to tender their Old Notes according to the guaranteed
delivery procedures set forth above.
 
WITHDRAWAL OF TENDERS
 
    Except as otherwise provided herein, Old Notes tendered pursuant to the
Exchange Offer may be withdrawn at any time prior to the Expiration Date.
 
    To withdraw a tender of Old Notes in the Exchange Offer, a written or
facsimile transmission notice of withdrawal must be received by the Exchange
Agent at its address set forth herein prior to the Expiration Date. Any such
notice of withdrawal must (i) specify the name of the person having deposited
the Old Notes to be withdrawn (the "Depositor"), (ii) identify the Old Notes to
be withdrawn (including the certificate number or numbers (except in the case of
book-entry tenders) and principal amount at maturity (regardless of the means of
tendering) of such Old Notes), (iii) be signed by the holder in the same manner
as the original signature on the Letter of Transmittal by which such Old Notes
were tendered (including any required signature guarantees) or be accompanied by
documents of transfer sufficient to have the Trustee with respect to the Old
Notes register the transfer of such Old Notes into the name of the Depositor
withdrawing the tender, and (iv) specify the name in which any such Old Notes
are to be registered, if different from that of the Depositor. If the Old Notes
have been tendered pursuant to the procedure for book-entry tender set forth
above under "Exchanging Book-Entry Old Notes," a notice of withdrawal must
specify, in lieu of certificate numbers, the name and account number at DTC to
be credited with the withdrawn Old Notes. All questions as to the validity, form
and eligibility (including time of receipt) of such notices will be determined
by the Company in its sole discretion, which determination shall be final and
binding on all parties. Any Old Notes so withdrawn will be deemed not to have
been validly tendered for purposes of the Exchange Offer and no New Notes will
be issued with respect thereto unless the Old Notes so withdrawn are validly
retendered. Properly withdrawn Old Notes may be retendered by following one of
the procedures described above under "Procedures for Tendering" at any time
prior to the Expiration Date.
 
    Any Old Notes which have been tendered but which are not accepted for
exchange due to rejection of tender or termination of the Exchange Offer, or
which have been validly withdrawn, will be returned as soon as practicable to
the holder thereof without cost to such holder.
 
CONDITIONS OF THE EXCHANGE OFFER
 
    Notwithstanding any other term of the Exchange Offer, the Company shall not
be required to accept for exchange, or exchange New Notes for, any Old Notes,
and may terminate the Exchange Offer as provided herein before the acceptance of
such Old Notes, if:
 
        (a) any action or proceeding is instituted or threatened in any court or
    by or before any governmental agency with respect to the Exchange Offer
    which, in the sole judgment of the Company, might materially impair the
    ability of the Company to proceed with the Exchange Offer or
 
                                       21
<PAGE>
    materially impair the contemplated benefits of the Exchange Offer to the
    Company, or any material adverse development has occurred in any existing
    action or proceeding with respect to the Company or any of its subsidiaries;
    or
 
        (b) any change, or any development involving a prospective change, in
    the business or financial affairs of the Company or any of its subsidiaries
    has occurred which, in the sole judgment of the Company, might materially
    impair the ability of the Company to proceed with the Exchange Offer or
    materially impair the contemplated benefits of the Exchange Offer to the
    Company, or
 
        (c) any law, statute, rule or regulation is proposed, adopted or
    enacted, which, in the sole judgment of the Company, might materially impair
    the ability of the Company to proceed with the Exchange Offer or materially
    impair the contemplated benefits of the Exchange Offer to the Company; or
 
        (d) any governmental approval has not been obtained, which approval the
    Company shall, in its sole discretion, deem necessary for the consummation
    of the Exchange Offer as contemplated hereby.
 
    If the Company determines in its sole discretion that any of the conditions
are not satisfied, the Company may (i) refuse to accept any Old Notes and return
(or, in the case of Old Notes tendered by book-entry transfer through DTC,
promptly credit to an account maintained with DTC) all tendered Old Notes to the
tendering holders, (ii) extend the Exchange Offer and retain all Old Notes
tendered prior to the Expiration Date, subject, however, to the rights of
holders to withdraw such Old Notes (see "-- Withdrawal of Tenders") or (iii)
waive such unsatisfied conditions with respect to the Exchange Offer and accept
all validly tendered Old Notes which have not been withdrawn. If such waiver
constitutes a material change to the Exchange Offer, the Company will promptly
disclose such waiver by means of a prospectus supplement that will be
distributed to the registered holders, and the Company will extend the Exchange
Offer for a period of five to ten business days, depending upon the significance
of the waiver and the manner of disclosure to the registered holders, if the
Exchange Offer would otherwise expire during such five to ten business day
period.
 
TERMINATION OF CERTAIN RIGHTS
 
    Holders of the Old Notes to whom this Exchange Offer is made have special
rights under the Registration Rights Agreement that will terminate upon the
Consummation of the Exchange Offer. Under the Registration Rights Agreement, the
Exchange Offer shall be deemed consummated (the "Consummation") upon the
occurrence of (i) the filing and effectiveness under the Securities Act of a
registration statement relating to the New Notes to be issued in the Exchange
Offer, (ii) the maintenance of such registration statement continuously
effective and the keeping of the Exchange Offer open for a period of not less
than the minimum period required under applicable federal and state securities
law (provided that in no event shall such Exchange Offer remain open and the
registration statement relating thereto remain continuously effective, in each
case, for less than 20 business days), and (iii) the delivery by the Company to
the Trustee under the Indenture of New Notes in the same aggregate principal
amount as the aggregate principal amount of Old Notes tendered by holders
thereof pursuant to the Exchange Offer. Such special rights which will terminate
include the right to require the Company to comply with the following: (a) to
file with the Commission a registration statement under the Securities Act with
respect to the New Notes on or before 60 days following the Closing Date, (b) to
use its reasonable best efforts to cause such registration statement to become
effective under the Securities Act as soon as practicable, but in no event later
than 120 days following the Closing Date, and (c) on or prior to 60 business
days after effectiveness of the registration statement, to commence the Exchange
Offer and offer to the holders of the Old Notes the opportunity to exchange
their Old Notes for a like principal amount at maturity of New Notes.

FEES AND EXPENSES
 
    The expenses of soliciting tenders will be borne by the Company. The
principal solicitations are being made by mail; however, additional
solicitations may be made by telegraph, telephone or in person by officers and
regular employees of the Company and its affiliates.
 
    The Company has not retained any dealer-manager in connection with the
Exchange Offer and will not make any payments to brokers, dealers or others
soliciting acceptance of the Exchange Offer. The Company, however, will pay the
Exchange Agent reasonable and customary fees for its services and will reimburse
it for its reasonable out-of-pocket expenses in connection therewith.
 
    The cash expenses to be incurred in connection with the Exchange Offer will
be paid by the Company and are estimated in the aggregate to be approximately
$100,000. Such expenses include fees and expenses of the Exchange Agent and
Trustee, accounting and legal fees and printing costs, among others.
 
    The Company will pay all transfer taxes, if any, applicable to the exchange
of Old Notes pursuant to the Exchange Offer. If, however, a transfer tax is
imposed for any reason other than the exchange of Old Notes pursuant to the
Exchange Offer, then the amount of any such transfer taxes (whether imposed on
the registered holder or any other persons) will be payable by the tendering
holder. If satisfactory evidence of payment of such taxes or exemption therefrom
is not submitted with the Letter of Transmittal, the amount of such transfer
taxes will be billed directly to such tendering holder.
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
    Old Notes which are not exchanged for New Notes pursuant to the Exchange
Offer will remain restricted securities under the Securities Act. Accordingly,
such Old Notes may be resold only (i) to a person who the seller reasonably
believes is a "qualified institutional buyer" as defined in Rule 144A under the
Securities Act ("QIB") in a transaction meeting the requirements of Rule 144A,
in a transaction meeting the requirements of Rule 144 under the Securities Act,
outside the U.S. to a foreign person in a transaction meeting the requirements
of Rule 904 under the Securities Act or in accordance with another exemption
from the registration requirements of the Securities Act (and based upon an
opinion of counsel if the Company so requests), (ii) to the Company or (iii)
pursuant to an effective registration statement, and, in each case, in
accordance with any applicable securities laws of any State of the United States
or any other applicable jurisdiction. Holders prohibited from participating in
the Exchange Offer have certain further registration rights under the
Registration Rights Agreement. See "-- Holders Prohibited from Participating in
Exchange Offer."
 
ACCOUNTING TREATMENT
 
    The carrying value of the Old Notes is not expected to be materially
different from the fair value of the New Notes at the time of the exchange.
Accordingly, no gain or loss for accounting purposes will be recognized by the
Company. The expenses of the Exchange Offer will be amortized by the Company
over the term of the New Notes.

                                USE OF PROCEEDS
 
    The Company will receive no proceeds from the exchange of New Notes for Old
Notes.
 
    The net proceeds from the sale of Old Notes were $122,187,500, after
deducting fees and expenses of $2,812,500. The net proceeds were used to fund a
portion of the redemption of the Company's 11 1/2% Senior Subordinated Notes due
September 1, 1999, in an aggregate outstanding amount of $224 million as of June
30, 1996.

PAPERBOARD AND PAPER PACKAGING
 
    The Company believes that its integrated unbleached paperboard and paper
packaging business is the largest in the world with 16 mills and 149 converting
plants located throughout the United States and Canada, and in Europe, Australia
and China. The major products in this business are containerboard and corrugated
containers, which are primarily sold to a broad range of manufacturers of
consumable and durable goods; kraft paper and paper bags and sacks, which are
sold primarily to supermarket chains, retailers of consumer products and, in the
case of multiwall shipping sacks, to the agricultural, chemical and cement
industries; and boxboard and folding cartons, which are sold to manufacturers of
consumable goods and other box manufacturers. The unbleached packaging business
of the Company has an annual capacity of approximately 5.5 million tons and is
more than 80% integrated. In 1995, total sales for the paperboard and paper
packaging business of the Company were approximately $5.4 billion, or
approximately 74% of total consolidated sales.
 
    The paperboard and packaging business requires a large volume of recycled
fiber for its paperboard and paper packaging business. In 1995, the Company
processed approximately 2.6 million tons
 
                                       26

of recycled fiber. Recycled fiber is obtained from a variety of sources,
including through Paper Recycling International L.P. ("PRI"), a fifty
percent-owned joint venture. PRI is paid a fee by the Company for procuring
recycled fiber. See "-- Fiber Supply."
 
CONTAINERBOARD AND CORRUGATED SHIPPING CONTAINERS
 
    The Company believes it is the world's largest producer of containerboard,
of which more than 80% is converted by the Company into corrugated shipping
containers. The Company's total sales of corrugated shipping containers in 1995
were $3.1 billion.
 
    The Company's mills produce containerboard, including unbleached kraft
linerboard, recycled linerboard, medium and paper. Containerboard tons produced
and converted for the last three years were:

    Containerboard is produced at the Company's mills located in Snowflake,
Arizona; Jacksonville, Florida; Panama City, Florida; Port Wentworth, Georgia;
Hoya, Germany; Hodge, Louisiana; Missoula, Montana; New Richmond, Quebec;
Florence, South Carolina and Hopewell, Virginia. Corrugating medium is produced
at the Company's mills located in Uncasville, Connecticut; Hoya, Germany;
Viersen, Germany; Hodge, Louisiana; Ontonagon, Michigan; Bathurst, New
Brunswick; Coshocton, Ohio and York, Pennsylvania.
 
    The Company's containerboard and corrugated container operations are more
than 80% integrated and the Company believes this integration enhances its
ability to respond quickly and efficiently to customers and to fill orders on
short lead times. The Company believes it is the largest producer of corrugated
shipping containers in the U.S., with more than 100 containerboard converting
operations. Corrugated shipping containers, manufactured from containerboard in
converting plants, are used to ship such diverse products as home appliances,
electric motors, small machinery, grocery products, produce, books, tobacco and
furniture, and for many other applications. The Company stresses the value-added
aspects of its corrugated containers, such as labeling and multi-color graphics,
to differentiate its products and respond to customer requirements. The
Company's container plants serve local customers and large national accounts and
are located in the United States, Australia, Belgium, Canada, China, France,
Germany and Mexico, generally in or near large metropolitan areas. Corrugated
shipping container sales volume for 1995, 1994 and 1993 were 53.0, 54.1 and 52.5
billion square feet, respectively.
 
KRAFT PAPER AND BAGS AND SACKS
 
    The Company also has a highly integrated kraft paper and converted product
operation and is a net buyer of kraft paper from third parties. The Company
operates 18 paper converting facilities, which shipped approximately 574
thousand tons and 654 thousand tons of paper bags and sacks nationwide in 1995
and 1994, respectively. The Company believes it is the largest producer of
grocery bags and sacks. Kraft paper volume produced and converted for the last
three years was:

City, Florida; Hodge, Louisiana; Trois-Rivieres, Quebec and Florence, South
Carolina.
 
                                       27
<PAGE>
    Grocery bags and sacks are sold primarily to supermarket chains, and
merchandise bags are sold to retailers of consumer products. Multiwall shipping
sacks, considered a premium product, are sold to the agricultural, chemical and
cement industries, among other industries. The Company's total sales of bags and
sacks in 1995 were $743 million. In July 1996, the Company combined its retail
packaging business with that of Gaylord Container Corporation in a new joint
venture company.
 
MARKET PULP
 
    The Company believes it has a major market position in North America in the
production of market pulp. The Company owns and operates five market pulp mills
in North America, including mills in Panama City, Florida; Port Wentworth,
Georgia; Bathurst, New Brunswick; and Portage-du-Fort, Quebec and including the
Celgar mill in Castlegar, British Columbia in which the Company has a 45%
interest. These mills have the capacity to produce 1.2 million tons of market
pulp annually and produced 1.1 million tons in 1995 (including 45% of the
production at the Celgar mill). Total sales of market pulp (including 45% of the
Celgar mill) approximated $750 million in 1995. In addition, Stone-Consolidated
owns and operates the Fort Frances, Ontario mill, which has an annual capacity
of approximately 130 thousand tons of market pulp. The geographic diversity of
the Company's mills enables the Company to offer its customers a product mix of
bleached northern and southern hardwood and bleached northern softwood pulp.
Market pulp is sold to manufacturers of paper products, including fine papers,
photographic papers, tissue and newsprint.
 
NEWSPRINT AND UNCOATED GROUNDWOOD PAPER
 
    The Company has an equity interest of approximately 47% in
Stone-Consolidated, which is the resulting entity from the Amalgamation of the
Company's formerly 75% owned subsidiary of the same name and Rainy River Forest
Products, Inc. The Company accounts for Stone-Consolidated in accordance with
the equity method of accounting. The Company believes that Stone-Consolidated is
the largest producer of uncoated groundwood paper in North America and one of
the two largest in the world, and the second largest producer and largest
marketer of newsprint in the world. Stone-Consolidated has an annual production
capacity of 2.4 million tons of newsprint (including the Company's newsprint
mill in Snowflake, Arizona, the entire production of which is sold by
Stone-Consolidated on a commission basis, and Boise Cascade Corporation's
newsprint mill in DeRidder, Louisiana, the entire production of which is
purchased at a discount and sold by Stone-Consolidated) and 803 thousand tons of
uncoated groundwood paper. Newsprint is marketed to newspaper publishers and
commercial printers. Uncoated groundwood paper is sold for use primarily in
newspaper inserts, retail store advertising fliers, magazines, telephone
directories and as computer paper.
 
NEWSPRINT
 
    Stone-Consolidated owns and operates five newsprint mills located in
Shawinigan (Belgo mill) and Ville de La Baie (Port Alfred mill), Quebec; Kenora,
Ontario; West Tacoma, Washington and Ellesmere Port (Bridgewater mill), United
Kingdom. The Company owns and operates a fully integrated newsprint mill in
Snowflake, Arizona, the output of which Stone-Consolidated sells on a commission
basis. In addition, Stone-Consolidated also purchases at a discount and sells
the output of Boise Cascade Corporation's newsprint mill in DeRidder, Louisiana.
Stone-Consolidated's production of newsprint for 1995, on a pro forma basis
adjusted to reflect the effect of the Amalgamation as if it occurred January 1,
1995, was approximately 1.5 million tons. Sales of newsprint for
Stone-Consolidated on the same pro forma basis were approximately $1.2 billion.
Newsprint is primarily purchased by newspaper publishers and commercial
printers.
 
    The newsprint produced by the Company contains a significant percentage of
recycled fiber from de-inked pulp using flotation de-inking ("FDI") technology.
Management believes that the ability to produce newsprint with recycled content
has become an important competitive factor. Management anticipates that the
demand for newsprint with recycled content will continue to grow as a result of
further legislative activity and customer preferences, although at a slower rate
than in recent years. While an increasing number of producers are gaining the
ability to supply newsprint with recycled content, management believes its
de-inking facilities and the relative proximity of the mills to reliable sources
of
 
                                       28
<PAGE>
waste paper from urban centers will give the Company a competitive advantage
with customers who demand newsprint with recycled content, although there can be
no assurances that the Company will be able to maintain such a competitive
advantage.
 
UNCOATED GROUNDWOOD PAPERS
 
    The principal uncoated groundwood paper production facilities which are
owned by Stone-Consolidated include five paper machines located at the
Grand-Mere (Laurentide) and Trois-Rivieres (Wayagamack), Quebec mills and an
uncoated groundwood paper mill in Fort Frances, Ontario; smaller quantities of
uncoated groundwood papers are also produced on other machines located at the
Ellesmere Port (Bridgewater) and Shawinigan (Belgo) mills. Stone-Consolidated's
production of uncoated groundwood papers for 1995, on a pro forma basis adjusted
to reflect the effect of the Amalgamation as if it occurred January 1, 1995, was
approximately 815 thousand tons. Sales of uncoated groundwood papers from
Stone-Consolidated on the same pro forma basis were approximately $583 million.
 
    Uncoated groundwood papers are manufactured using production processes
similar to those used for newsprint but are generally of higher quality and
command higher prices and higher operating margins. The principal grades of
uncoated groundwood papers manufactured and sold by Stone-Consolidated are
directory papers, rotogravure and offset papers used in newspaper inserts,
retail store advertising fliers, Sunday magazines and other periodicals, bulky
book papers used for mass circulation paperback novels and form papers for use
in the manufacture of computer printout and other business forms. Major
customers for rotogravure and offset papers include major retailers, publishers
of Sunday magazines and other periodicals and major commercial printers. Major
customers for directory papers include telephone companies and independent
publishers of telephone directories and large commercial printers.
 
FIBER SUPPLY
 
    Wood fiber, particularly from wood chips, and waste paper constitute the
basic raw materials for linerboard, corrugating medium, unbleached kraft paper
and market pulp. Wood fiber resources are available within economic proximity of
the mills, and the Company has not experienced any significant difficulty in
obtaining such resources, although environmental concerns in the Pacific
Northwest (including the designation of the spotted owl as a threatened species)
and the Southwestern United States have reduced the supply of wood in those
regions. Consistent with its strategy to obtain long-term wood fiber sources
without the costs associated with land ownership, the Company sold approximately
329 thousand acres of timberland during the years 1988 through 1992. This
acreage had been owned by Southwest Forest Industries, Inc., which was acquired
by the Company in 1987. At December 31, 1995, the Company owned approximately 9
thousand and 137 thousand acres of private fee timberland in the United States
and Canada, respectively. The Company assists certain landowners in the
southeastern United States in managing approximately 2.0 million acres of
timberland.
 
    Wood fiber and recycled fiber are purchased in highly competitive, price
sensitive markets. These raw materials have historically exhibited price and
demand cyclicality. In addition, the supply and price of wood fiber, in
particular, are dependent upon a variety of factors over which the Company has
no control, including environmental and conservation regulations, natural
disasters, such as forest fires and hurricanes, and weather. The Company
purchases or cuts a variety of species of timber from which the Company utilizes
wood fiber depending upon the product being manufactured and each mill's
geographic location. A decrease in the supply of wood fiber has caused, and will
likely continue to cause, higher wood fiber costs in some of the regions in
which the Company procures wood.
 
    The increase in demand for products manufactured, in whole or in part, from
recycled fiber has caused a tightness in supply of recycled fiber and a
resulting significant increase in the cost of such fiber used in the manufacture
of recycled containerboard and other products. As a result, the Company's costs
for recycled fiber increased significantly in 1995 and, although they have
moderated from the peak levels of 1995, such costs are likely to continue to
fluctuate based upon demand/supply characteristics. Given the volatility of the
recycled fiber market, there can be no assurance that such costs will not reach
 
                                       29
<PAGE>
the peak levels of 1995. The Company's paperboard and paper packaging products
use a large volume of recycled fiber. While the Company has not experienced any
significant difficulty in obtaining wood fiber and recycled fiber in economic
proximity to its mills, there can be no assurances that this will continue to be
the case for any or all of its mills.
 
MARKETS AND COMPETITION
 
    The major markets in which the Company sells its principal products are
highly competitive. Its products compete with similar products manufactured by
others and, in some instances, with products manufactured from other materials.
Areas of competition include price, innovation, quality and service. The
Company's business is affected by cyclical industry conditions and economic
factors such as industry capacity, growth in the economy, interest rates,
unemployment levels and fluctuations in foreign currency exchange rates.
 
    The Company's products and the raw materials needed to manufacture those
products have historically exhibited price and demand cyclicality. Cyclical
economic factors such as growth in the economy generally, interest rates,
unemployment levels and fluctuations in currency exchange rates as well as
certain industry conditions, such as production capacity, have had a significant
impact on prices and sales of the Company's products. The availability and cost
of wood fiber, including wood chips, and waste paper may be subject to
substantial variation, depending upon economic, political and conservation
considerations.
 
    The Company's business is not dependent upon a single customer or upon a
small number of major customers. The loss of any one customer would not have a
material adverse effect on the Company.
 
    Backlogs are not a significant factor in the industry in which the Company
operates; most orders placed with the Company are for delivery within 60 days or
less.
 
    The Company owns patents, licenses, trademarks and tradenames on products.
The loss of any patent, license, trademark or tradename would not have a
material adverse effect on the Company's operations.
 
EMPLOYEES
 
    As of December 31, 1995, the Company had approximately 25,900 employees, of
whom approximately 21,700 were employees of U.S. operations and the remainder
were employees of foreign operations. Of those in the United States,
approximately 14,000 are union employees.
 
LEGAL PROCEEDINGS
 
    In November 1990, the U.S. Environmental Protection Agency ("EPA") announced
its decision to list two bodies of water in Arizona, Dry Lake and Twin Lakes, as
"waters of the United States" impacted by toxic pollutant discharges under
Section 304(l) of the federal Clean Water Act. These bodies of water have been
used by the Company's Snowflake, Arizona pulp and paper mill for the evaporation
of its process wastewater. The EPA is preparing a draft consent decree to
resolve the alleged past unpermitted discharges which will include the EPA's
proposal that the Company pay civil penalties in the amount of $900,000. The
Company has vigorously disputed the application of the Clean Water Act to these
two privately owned evaporation ponds. The Company has begun implementation of a
plan to use its wastewater to irrigate a biomass plantation and discontinue
using Dry Lake to evaporate wastewater. It is premature to predict the amount of
penalties, if any, that will eventually be assessed.
 
    On October 27, 1992, the Florida Department of Environmental Regulation,
predecessor to the Department of Environmental Protection ("DEP"), filed a civil
complaint in the Fourteenth Judicial Circuit Court of Bay County, Florida
against the Company seeking injunctive relief, an unspecified amount of fines
and civil penalties, and other relief based on alleged groundwater contamination
at the Company's Panama City, Florida pulp and paperboard mill. In addition, the
complaint alleges operation of a solid waste facility without a permit and
discrepancies in hazardous waste shipping manifests. Because of
 
                                       30
<PAGE>
uncertainties in the interpretation and application of DEP's rules, it is
premature to assess the Company's potential liability, if any, in the event of
an adverse ruling. At the parties' request, the case has been placed in abeyance
pending the conclusion of a related administrative proceeding petitioned by the
Company following DEP's proposal to deny to the Company a permit renewal to
continue operating its wastewater pretreatment facility at the mill site. The
administrative proceeding has been referred to a hearing officer for an
administrative hearing on the consolidated issues of compliance with a prior
consent order, denial of the permit renewal, completion of a contamination
assessment and denial of a sodium exemption. The consolidated cases were abated
at the parties' request and extensive settlement negotiations are being
conducted between the parties. The Company intends to vigorously assert its
entitlement to the permit renewal and to defend against the groundwater
contamination and unpermitted facility allegations in the event that a
settlement cannot be reached.
 
    On April 20, 1994, Carolina Power & Light ("CP&L") commenced proceedings
(the "FERC Proceeding") against the Company before the Federal Energy Regulatory
Commission ("FERC") and in the United States District Court for the Eastern
District of North Carolina (the "Federal Court Action"). Both proceedings relate
to the Company's electric cogeneration facility located at its Florence, South
Carolina mill (the "Facility") and the Company's Electric Power Purchase
Agreement (the "Agreement") with CP&L.
 
    In the FERC Proceeding, CP&L alleges that the Facility lost its qualifying
facility ("QF") certification under the Public Utility Regulatory Policy Act of
1978 on August 13, 1991, when the Agreement, pursuant to which CP&L purchases
electricity generated by the Facility, was amended to reflect the Company's
election under the Agreement to switch to a "buy-all/sell-all mode of
operation". As a result, CP&L alleges, the Company became a "public utility" on
August 13, 1991 subject to FERC regulation under the Federal Power Act. CP&L has
also requested that the FERC determine the "just and reasonable rate" for sales
of electric energy and capacity from the Facility since August 13, 1991 and
order the Company to refund any amounts paid in excess of that rate, plus
interest and penalties.
 
    In its answer filed with the FERC on June 2, 1994, the Company stated that
its power sales to CP&L fully complied with the FERC's regulations. The Company
also requested that the FERC waive compliance with any applicable FERC
regulations in the event that the FERC should determine, contrary to the
Company's position, that the Company has not complied with the FERC's
regulations in any respect. If the FERC were to determine that the Company had
become a "public utility," the Company's issuance of securities and incurrence
of debt after the date that it became a "public utility" could be subject to the
jurisdiction and approval of the FERC unless the FERC granted a waiver. In the
absence of such a waiver, certain other activities and contracts of the Company
after such date could also be subject to additional federal and state regulatory
requirements, and defaults might be created under certain existing agreements.
Based on the past administrative practice of the FERC in granting waivers of
certain other regulations, the Company believes that it is likely that such a
waiver would be granted by the FERC in the event that such a waiver became
necessary.
 
    In the Federal Court Action, CP&L has requested a declaratory judgment that
sales of electric energy and capacity under the Agreement since August 13, 1991
are subject to a just and reasonable rate to be determined by the FERC and that
the Agreement has been terminated as a result of the Company's failure to
maintain the Facility's QF status and the invalidity of the Agreement's rate
provisions. CP&L has also sought damages for breach of contract and for
purchases in excess of the just and reasonable rate to be determined by the
FERC. On June 9, 1994, the Company moved to dismiss CP&L's Federal Court Action
on the principal grounds that any proceedings in the United States District
Court are premature unless and until the FERC Proceeding is finally resolved. On
September 20, 1994, the United States District Court stayed the Federal Court
Action pending the outcome of the FERC proceeding.
 
    The two proceedings are in their preliminary stages and no assurance can be
provided as to the timing of the decisions or the outcome of either of them. The
Company intends to contest these actions vigorously.
 
                                       31
<PAGE>
    On September 30, 1994, the EPA, Region IV, issued an Administrative Order
(the "Order") to the Company's Panama City mill pursuant to Section 3008(h) of
the Federal Resource Conservation and Recovery Act ("RCRA"), 42
U.S.C.Section6928(h)(1). The Order requires the Company to perform a RCRA
Facility Investigation at the Panama City mill together with confirmatory
sampling, interim corrective measures and any other activities necessary to
correct alleged actual or threatened releases of hazardous substances or
hazardous constituents at or from the Panama City mill. The Company has filed a
protest and requested a hearing to contest the EPA's RCRA Section 3008(h)
jurisdiction over the Panama City mill and the parties have been engaged in
extensive settlement negotiations. The Company believes that the Panama City
mill is not currently a RCRA facility. The corrective measures mandated by the
Order would require the Company to conduct extensive groundwater and soil
sampling and analyses. The Company does not know at this time the likelihood of
success in challenging the Order. Notwithstanding the success in challenging the
Order, an owner of property adjacent to the Panama City mill is currently
subject to extensive clean-up under RCRA, and the EPA is empowered to require
clean-up for materials discharged from the property which may have migrated onto
the Panama City mill's property. The Company does not yet know the extent, if
any, of such adjacent property owner's responsibility to remediate
contamination, if any, at the Panama City mill site.
 
    On January 22, 1996, the United States of America filed a suit against the
Company in the United States District Court for the District of Montana seeking
injunctive relief and an unspecified amount in civil penalties based on the
alleged failure of the Company to comply with certain provisions of the Clean
Air Act ("CAA"), its implementing regulations, and the Montana State
Implementation Plan at the Company's Missoula, Montana kraft pulp mill (the
"Missoula Mill"). The complaint specifically alleges that the Company exceeded
the 20% opacity limitation for recovery boiler emissions, failed to properly set
the span on a recovery boiler continuous monitor, and concealed the emission of
an air contaminant by improperly venting non-condensible gases. The statutory
penalty for violations of the CAA is $25,000 per day for each day of violation.
The Company is reviewing the matter with counsel to assess its potential
liability. It is premature to predict the outcome of this matter at this time.
 
    In a related matter, on November 27, 1995, the Company received notice from
several environmental groups that they intended to file citizens suits under the
CAA, the Federal Water Pollution Control Act ("CWA") and the Emergency Planning
and Community Right-to-Know Act ("EPCRA") against the Company based on alleged
violations of those Acts at the Missoula Mill. In December, 1995,
representatives of the Company met with representatives of the groups that sent
the notice to discuss the Company's position that the majority of the alleged
violations were not in excess of applicable permit limits or were excused
because they occurred during reported malfunctions or start-up or shutdown
conditions. On January 29, 1996, a Complaint was filed by the Montana Coalition
for Health, Environmental and Economic Rights Inc., Cold Mountain, Cold Rivers,
Inc. and Native Forest Network, Inc. (collectively, "Plaintiffs") in the United
States District Court for the District of Montana alleging numerous violations
of the provisions of the CAA, the CWA and the EPCRA. On February 7, 1996,
Plaintiffs filed an Amended Complaint seeking (1) a declaratory judgment that
the Company has violated Section 301(a) of the CWA, Section 502(a) of the CAA
and Section 313 of the EPCRA; (2) injunctive relief enjoining the Company from
operating the Missoula Mill in a manner as will result in further violations of
the CAA, CWA and EPCRA; and (3) civil penalties of $25,000 per day for each day
of alleged violation. The Company intends to vigorously contest the allegations.
 
    In addition, the Company is involved in contractual disputes, administrative
and legal proceedings and investigations of various types other than those
described above. Although any such litigation, proceeding or investigation has
an element of uncertainty, the Company believes that the outcome of any such
proceeding, lawsuit or claim which is pending or threatened, or all of them
combined, other than those described above, would not have a material adverse
effect on its consolidated financial position, liquidity or results of
operations.

                                CREDIT AGREEMENT
 
CREDIT AGREEMENT
 
    In October 1994, the Company entered into a credit agreement which has been
amended and restated in August 1995 and March 1996 (as amended and restated the
"Credit Agreement"). The Credit Agreement consists of a $400 million senior
secured term loan maturing through April 1, 2000, $390 million senior secured
term loans maturing through October 1, 2003 and a $560 million senior secured
revolving credit facility commitment maturing May 15, 1999. The Credit Agreement
also provides for the issuance of letters of credit which, to the extent
utilized, will serve to reduce borrowing availability under the revolving credit
facility of the Credit Agreement.
 
    The following summaries of certain provisions of the Credit Agreement do not
purport to be complete and are subject to, and are qualified in their entirety
by express reference to, all the provisions of the Credit Agreement, including
the definitions therein of certain terms. Certain capitalized terms under this
caption are defined in the Credit Agreement.
 
MATURITIES AND MANDATORY PREPAYMENTS
 
    The initial $400 million term loan under the Credit Agreement will mature on
April 1, 2000. Amounts outstanding under the term loan amortize on a semi-annual
basis (April 1 and October 1) based upon the applicable percentage of the
principal amount of the initial term loan. Amortization amounts are .5% of
principal amount for the period from April 1, 1995 through April 1, 1999, 47.5%
on October 1, 1999 and 48.0% on April 1, 2000. The $390 million term loans will
mature on October 1, 2003. Amounts outstanding under the $390 million term loans
amortize on a semi-annual basis (April 1 and October 1) based upon the
applicable percentage of the initial principal amount of the additional term
loan. Amortization amounts for the $200 million term loan component are .5% of
principal amount for the period April 1, 1996 through October 1, 2002 and 46.5%
April 1 and October 1, 2003. Amortizations for the $190 million term loan
component are .5% of principal amount for the period from October 1, 1996
through October 1, 2002, 46.5% on April 1, 2003 and 47% on October 1, 2003. The
$560 million revolving credit facility will mature on May 15, 1999.
 
    Mandatory prepayments are required under the term loan and additional term
loan portions of the Credit Agreement as follows: (i) 50% (subject to
performance-related step downs to 25%) of Excess Cash Flow (as defined in the
Credit Agreement) for each fiscal quarter, excluding the first $50 million of
Excess Cash Flow in each fiscal year; (ii) 100% of the net proceeds of (a) the
issuance or incurrence of additional indebtedness (excluding certain specified
refinancings and $400 million (the "Debt Basket") of other debt), and (b)
certain non-ordinary course asset sales (excluding $300 million (the "Asset
Basket") of proceeds from such sales (other than sales of Collateral or
collateral under the Credit Agreement pledged to the lenders under the Credit
Agreement (the "Bank Collateral")), in each case for which substitute collateral
is not provided). The lenders under the Credit Agreement have waived the
mandatory prepayment from Excess Cash Flow requirement for the fiscal quarters
ending June 30, 1995 through and including March 31, 1996. Additionally, the
Company has no mandatory prepayments under the $190 million term loan facility
until September 30, 1997, and Lenders of approximately 81% of the principal
amount of the other term loans have waived mandatory payments until September
30, 1997. All mandatory prepayments (except mandatory redemptions related to
sales of Bank Collateral) will be allocated entirely against the term loan and
additional term loan amortization in inverse order of maturity. In addition,
mandatory prepayments from sales of Bank Collateral (unless substitute
collateral has been provided) will be allocated pro rata between the term loan
and additional term loan (and applied in inverse order of maturity) on the one
hand and the revolving credit facility, on the other, and, in the case of the
revolving credit facility, will result in a corresponding permanent commitment
reduction.
 
    At the Company's request, the holders of loans under the term loan or
additional term loan may, acting individually, waive their individual right to
any mandatory prepayment, in which case the amounts otherwise payable to such
holders may be retained by the Company. The cash flow in excess of the required
mandatory repayment, the net proceeds from the Debt Basket, the net proceeds
from the Asset
 
                                       33
<PAGE>
Basket, and waived prepayment obligations may be used for (i) general corporate
purposes, (ii) capital expenditures, acquisitions or investments in excess of
annual limitations (without reducing permitted basket amounts) and (iii)
prepayment of debt securities ("Permitted Uses").
 
    The Company is also permitted to voluntarily reduce the unutilized portion
of the revolving credit facility and voluntarily prepay the term loan and
additional term loan, with voluntary term loan and additional term loan
prepayments to be applied against amortization in inverse order of maturity.
Voluntary prepayments of the term loan and additional term loan must be
proportionate with one another.
 
INTEREST RATES
 
    The Credit Agreement permits the Company to choose among various interest
rate options for the revolving credit facility and the term loan and to specify
the interest rate period to which the interest rate options are to apply,
subject to certain parameters. The applicable interest rate options available to
the Company are: (i) under the revolving credit facility (a) the higher of (1)
Bankers Trust Company's prime rate and (2) the Federal Funds Effective Rate plus
1/2 of 1% (the alternative base rate ("ABR")) plus, in the case of (1) or (2),
1 5/8% per annum or (b) the London Interbank Offered Rate ("LIBOR") plus 2 5/8%
per annum; (ii) under the swing-line sub-facility, ABR plus 1 5/8% per annum;
(iii) under the term loan, ABR plus 2 1/8% per annum or LIBOR plus 3 1/8% per
annum; (iv) under the $200 million term loan and the $190 million term loan, ABR
plus 2 3/8% per annum or LIBOR plus 3 3/8% per annum. Upon achievement of
specified indebtedness ratios and cash flow coverage ratios or other performance
related tests, the interest rate margins for the revolving credit facility
(including the swing-line sub-facility) will be reduced. Additionally, the
Company pays a 1/2% commitment fee on the unused portions of the revolving
credit facility but without giving effect to reductions in availability for
swing-line loans and letters of credit outstanding. The Company will pay a fee
on the outstanding letters of credit issued under the revolving credit facility
at a rate equal to LIBOR plus 2 5/8%.
 
SECURITY
 
    All indebtedness under the Credit Agreement is secured by a significant
portion of the assets of the Company. Loans and letters of credit under the
Credit Agreement are secured by a mortgage on the following mills and box plants
owned or leased by the Company or its subsidiaries, as well as liens on the
machinery, equipment and inventory located at each mill or box plant:

</TABLE>
 
COVENANTS
 
    The Credit Agreement contains covenants that include, among other things,
the maintenance of certain financial tests and ratios. Additionally, the term
loan portions of the Credit Agreement provide for mandatory prepayments from
sales of certain assets, certain debt financings and a percentage of excess cash
flow (as defined). The Company's bank lenders, at the Company's optional
request, may at their option, waive the receipt of certain mandatory
prepayments. Any mandatory and voluntary prepayments are allocated against the
term loan amortization in inverse order of maturity. Mandatory prepayments from
sales of collateral, unless replacement collateral is provided, will be applied
ratably to the term loans and revolving credit facility, permanently reducing
the loan commitments under the Credit Agreement. The Credit Agreement also
contains cross-default provisions to the indebtedness of $10 million or more of
the Company and certain subsidiaries.

</TABLE>
 
    At June 30, 1996, the Company's interest coverage ratio was 2.55 to 1. The
Company is currently seeking an amendment with respect to certain covenants
under the Credit Agreement, including indebtedness ratio and interest coverage
ratio covenants, for periods including the fourth quarter of 1996 and the first
three quarters of 1997.
 
RESTRICTIONS ON INVESTMENTS IN SUBSIDIARIES AND GUARANTEES; CROSS-DEFAULTS
 
    The Credit Agreement contains restrictions on investments in
Stone-Consolidated and SVCPI. The Company is also not permitted to guarantee the
indebtedness of Stone-Consolidated or SVCPI and there are restrictions on other
guarantees. There are also restrictions on transactions with affiliates which
are not wholly-owned subsidiaries. Any event of default or default with respect
to the Company's or a Subsidiary's (as defined in the Credit Agreement)
indebtedness for money borrowed having an aggregate principal amount of $10
million or more constitutes an event of default under the Credit Agreement.
 
RESTRICTIONS ON DIVIDENDS
 
    The Credit Agreement provides that the Company's dividend payments,
distributions or purchases of any class of capital stock of the Company and its
subsidiaries cannot exceed the sum of an amount (the "Dividend Basket") equal to
(i) 75% of the Consolidated Net Income (as defined by the Credit Agreement) of
the Company from October 1, 1994 to the date of payment of such dividends, minus
(ii) 100% of the Consolidated Net Loss (as defined by the Credit Agreement) of
the Company from October 1, 1994 to the date of payment of such dividend plus
(iii) 100% of any net cash proceeds from sales of common stock or certain
preferred stock of the Company from the closing date to the date of payment of
such dividends, minus (iv) the total of certain permitted investments and
permitted capital expenditures, which the Company will be permitted to make in
lieu of dividends the Company would be permitted to pay pursuant to this
dividend formula. For purposes of calculating the Dividend Basket, Consolidated
Net Income is deemed not to include the charge to earnings related to the
purchases of the Company's 8 7/8% Convertible Notes and the non-cash
extraordinary loss due to the early extinguishment of debt resulting therefrom.
In addition, the Credit Agreement permits the Company to pay dividends on its
preferred stock outstanding on the date of the Credit Agreement to the extent
permitted by the Company's senior subordinated indenture dated as of March 1992.
 
RESTRICTIONS ON INCURRENCE OF INDEBTEDNESS
 
    The Credit Agreement restricts the incurrence of additional indebtedness,
subject to certain exceptions (including the refinancing of existing
indebtedness).

                              DESCRIPTION OF NOTES
 
    The Old Notes have been and the New Notes will be issued under an Indenture
dated as of July 24, 1996, as supplemented and amended by the First Supplemental
Indenture dated as of July 24, 1996 (the "Indenture"), between the Company and
The Bank of New York, as trustee (the "Trustee"). All references to "Securities"
shall refer to debt securities issued under the Indenture, as it may be
supplemented and amended from time to time. The following summaries of certain
provisions of the Notes and the Indenture do not purport to be complete and are
subject to, and are qualified in their entirety by express reference to, all the
provisions of the Indenture, including the definitions therein of certain terms.
Copies of the Indenture, are available from the Company. Certain capitalized
terms herein are defined in the Indenture.
 
GENERAL
 
    The Indenture does not limit the aggregate principal amount of Securities
which may be issued thereunder and provides that Securities may be issued
thereunder from time to time in one or more series. The Notes will be senior
unsecured obligations of the Company. The principal of, and any premium or
interest on, the Notes will be payable, and the Notes will be exchangeable and
transfers thereof will be registrable, at the Place of Payment set forth in the
Indenture, provided that, at the option of the Company, payment of interest may
be made by check mailed to the address of the person entitled thereto as it
appears in the Register relating to such Notes.
 
    The Notes will be issued in United States dollars in denominations of $1,000
or any integral multiple thereof. No service charge will be made for any
transfer or exchange of the Notes, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith.
 
    With respect to any Deficiency Offer, Change of Control Offer, Asset
Disposition Offer or Non-Investment Grade Repurchase Offer or optional
redemption of the Notes, the Company shall comply with the requirements of
Section 14(e) and Rule 14e-1 under the Exchange Act, as applicable.
 
RANKING
 
    The Notes will rank pari passu in right of payment with all existing and
future Senior Indebtedness of the Company and senior in right of payment and
rights upon liquidation to all existing and future Subordinated Indebtedness of
the Company.
 
    A significant portion of the Company's assets secure borrowings outstanding
under the Credit Agreement. See "Credit Agreement -- Credit Agreement --
Security." Likewise, the Company has issued $500 million of First Mortgage Notes
secured by four of the Company's mills and related assets and a special purpose
subsidiary of the Company has issued $260 million of floating rate receivables-
backed notes and a $50 million revolving receivables-backed note (collectively,
the "Receivables-Backed Notes"). In the event of the Company's insolvency or
liquidation, the claims of the lenders under the Credit Agreement, the holders
of the First Mortgage Notes and the holders of Receivables-Backed Notes would
have to be satisfied out of the collateral securing such obligations before any
such assets would be available to pay claims of holders of the Notes and other
holders of Senior Indebtedness of the Company (including such secured lenders to
the extent that they are not satisfied out of the proceeds of their collateral).
If the lenders under the Company's secured indebtedness should foreclose on
their respective collateral, no assurance can be given that there will be
sufficient assets available in the Company to pay amounts due on the Notes.
 
    The Notes are obligations exclusively of the Company. Because certain of the
operations of the Company are currently conducted by subsidiaries (primarily
Stone Canada and its subsidiaries), the Company's cash flow and consequent
ability to service debt, including the Notes, are dependent, in part, upon the
earnings of its subsidiaries and the distribution of those earnings or upon
loans or other payments of funds by those subsidiaries to the Company. The
subsidiaries of the Company are separate and distinct legal entities and have no
obligation, contingent or otherwise, to pay any amount due pursuant to the Notes
or to make any funds available therefor, whether by dividends, loans or other
 
                                       36
<PAGE>
payments. In addition, the payment of dividends and the making of loans and
advances to the Company by its subsidiaries may be subject to statutory or
contractual restrictions (as well as potential foreign tax withholding under
certain circumstances), are contingent upon the earnings of those subsidiaries
and are subject to various business considerations. See "Risk Factors -- Credit
Agreement Restrictions."
 
    Any right of the Company to receive assets of any of its subsidiaries upon
their liquidation or reorganization (and the consequent right of the holders of
the Notes to participate in the distribution of or proceeds from those assets)
will be structurally subordinated to the claims of such subsidiary's creditors
(including trade creditors and holders of debt issued by such subsidiary),
except to the extent that the Company is itself recognized as a creditor of such
subsidiary, in which case the claims of the Company would still be subordinate
to any security interests in the assets of such subsidiary and any indebtedness
of such subsidiary senior to that held by the Company.
 
PRINCIPAL, MATURITY AND INTEREST
 
    The Notes will mature on August 1, 2016. The Notes are not redeemable at the
option of the Company prior to August 1, 2001. Thereafter, if an Investment
Grade Triggering Event has not occurred, the Notes may be redeemed at the option
of the Company, in whole or in part from time to time on not less than 30 days,
nor more than 45 days, prior notice, mailed by first class mail to the Note
holders' last addresses as they shall appear in the note register, at the
following prices (expressed as percentages of the principal amount of the
Notes), if redeemed during the twelve months beginning August 1 of the year
indicated below, in each case together with interest accrued to the Redemption
Date:

<S>                                                                <C>

2004 and thereafter..............................................         100.00%
</TABLE>
 
    If an Investment Grade Triggering Event has occurred, the Notes will not be
redeemable at the option of the Company until the fifteenth day following the
date of the Investment Grade Triggering Event (the "Lock Determination Date").
If on the Lock Determination Date, (i) an Investment Grade Locking Event does
not occur, the Notes will be redeemable at the option of the Company as
described above, or (ii) an Investment Grade Locking Event occurs, the Notes
will not be redeemable at the option of the Company prior to August 1, 2011, and
thereafter the Notes may be redeemed at the option of the Company, in whole or
in part from time to time on not less than 30 days, nor more than 45 days, prior
notice, mailed by first class mail to the Note holders' last addresses as they
shall appear in the Note register, at 100% of the principal amount of the Notes,
together with interest accrued to the Redemption Date.
 
    Selection of Notes for redemption will be made by the Trustee, upon notice,
substantially pro rata, by lot, or by any other method that the Trustee
considers fair and appropriate. The Indenture provides that, if any Note is to
be redeemed in part only, the notice which relates to the redemption of such
Note shall state the portion of the principal amount to be redeemed, and shall
state that on or after the Redemption Date, upon surrender of such Note, a new
Note or Notes in principal amount equal to the unredeemed portion thereof will
be issued.
 
    The Notes will bear interest at the rate per annum shown on the cover page
of this Prospectus from the date of original issuance of the Notes or from the
most recent Interest Payment Date to which interest has been paid or provided
for, subject to adjustment as provided below, payable semi-annually in arrears
on February 1 and August 1 of each year, commencing February 1, 1997, to the
Holders in whose names the Notes are registered at the close of business on the
preceding January 15 and July 15, respectively.
 
    In the event that the Company is required but unable to make a Deficiency
Offer, the Reset Rate on the Notes will be the greater of (x) the Applicable
Rate then in effect and (y) the sum of (A) 400 basis points and (B) the higher
of the Seven Year Treasury Rate and the Ten Year Treasury Rate and shall
 
                                       37
<PAGE>
further increase by an additional 50 basis points on each succeeding Interest
Payment Date, provided, however that in no such event shall the interest rate at
any time exceed the Applicable Rate by more than 200 basis points. The Reset
Rate will be adjusted from time to time, if necessary, to reflect any change in
the Applicable Rate of the Notes.
 
INTEREST RATE ADJUSTMENT
 
    Unless and until an Investment Grade Locking Event has occurred, the
interest payable on the Notes shall be based upon the debt rating (the "Rating")
for the Notes as determined by Moody's or S&P or their successors (as described
below), and adjusted if necessary in response to changes in a Rating. On the
date of this Prospectus, the Moody's Rating is B1 and the S&P Rating is B+ for
the Notes. Based on these Ratings, the initial Applicable Rate (as hereinafter
defined) on the Notes will be 11.875% per annum. The Notes will bear interest at
the initial Applicable Rate from the date of issuance of the Notes until the
earlier of (a) the date the principal of the Notes is paid or made available for
payment or (b) the calendar day immediately preceding the calendar day on which
a change in Rating category (as set forth in the table below) takes effect in
either the Moody's Rating or S&P Rating for the Notes, except that in the case
of a change in Rating category that occurs between a Regular Record Date and an
Interest Payment Date, such day shall be such Interest Payment Date (each a
"Rating Adjustment Date"); provided, however, that prior to August 1, 1997, such
interest rate shall not be less than 11.875% per annum. Beginning on a Rating
Adjustment Date, if any, and to the earlier of the date the principal of the
Notes is paid or made available for payment or the calendar day immediately
preceding the next Rating Adjustment Date, if any, the Notes will bear interest
at the rate per annum (the "Applicable Rate") determined as follows: (i) in the
event of a change in Rating category that is an upward change, the Applicable
Rate shall be the interest rate set forth below opposite the higher of the
Moody's Rating or the S&P Rating assigned to the Notes in effect at the close of
business on that Rating Adjustment Date; (ii) in the event of a change in Rating
category that is a downward change, the Applicable Rate shall be the interest
rate set forth below opposite the lower of the Moody's Rating or the S&P Rating
assigned to the Notes in effect at the close of business on that Rating
Adjustment Date, PROVIDED, HOWEVER, that, for purposes of this clause (ii), if
after a downward change in Rating category the Moody's Rating and the S&P Rating
assigned to the Notes differ by more than one Rating category, the Applicable
Rate shall be the interest rate set forth opposite the Rating category that is
one Rating category below the higher of the two Ratings in effect at the close
of business on the Rating Adjustment Date. Notwithstanding the foregoing, if
both Moody's and S&P, on the same day, change their respective Ratings assigned
to the Notes and one such change is an upward change while the other such change
is a downward change, the Applicable Rate shall be determined in accordance with
clause (ii) above, including the proviso thereto. If only one Rating is
available on any Rating Adjustment Date, the Applicable Rate shall be determined
solely by reference to such one Rating.
 
    If neither Moody's nor S&P has a Rating in effect, then the Company shall,
with the approval of the Trustee, designate, as a substitute for Moody's or S&P,
as the case may be, a nationally recognized statistical rating organization (a
"Substitute Rating Agency"), and/or make adjustments in the relationship between
the Rating and the Applicable Rate, as are consistent with the table below. If,
for any period
 
                                       38
<PAGE>
prior to the occurrence of an Investment Grade Locking Event, no Substitute
Rating Agency shall have been so designated and a Substitute Rating Agency is
available, the Applicable Rate for such period shall be the highest Applicable
Rate set forth in the table below.

B3 or lower        B- or lower             13.080%
</TABLE>
 
    If any change in the Applicable Rate occurs during any interest payment
period, the Notes shall bear interest for such interest payment period at a rate
per annum equal to the weighted average of the Applicable Rates in effect during
such interest payment period, calculated by multiplying each Applicable Rate by
the number of days such Applicable Rate is in effect during each month of such
interest payment period, determining the sum of such products and dividing such
sum by the number of days in such interest payment period. All calculations
pursuant to the preceding sentence and of interest on the Notes will be computed
on the basis of a year of twelve 30-day months.
 
    If any change in the Applicable Rate occurs, the Company shall notify the
Trustee of the new Applicable Rate not later than five Business Days after the
applicable Rating Adjustment Date. Not later than five Business Days after the
Trustee has received such notice setting forth the new Applicable Rate, the
Trustee shall mail to each Holder of Notes such notice setting forth the new
Applicable Rate.
 
INTEREST RATE LOCK
 
    Upon the occurrence of an Investment Grade Locking Event, the interest rate
payable on the Notes will no longer be subject to adjustment and will be fixed
as described below. An "Investment Grade Locking Event" shall occur on the Lock
Determination Date -- the fifteenth day after the date of an Investment Grade
Triggering Event -- if, on such Lock Determination Date, the Rating assigned to
the Notes by S&P or Moody's or both is an Investment Grade Rating. An
"Investment Grade Triggering Event" shall occur on the first day on which the
Notes are assigned an Investment Grade Rating by either Moody's or S&P or both.
An "Investment Grade Rating" means a Moody's Rating of Baa3 or higher or an S&P
Rating of BBB- or higher. Upon the occurrence of an Investment Grade Locking
Event, the Notes will bear interest at the Applicable Rate set forth in the
table above opposite the higher of the Moody's Rating or the S&P Rating assigned
to the Notes in effect at the close of business on the date of the Investment
Grade Locking Event from such date until the principal of the Notes is paid or
made available for payment. Notwithstanding the foregoing, however, the interest
rate payable on the Notes prior to August 1, 1997 shall not be less than 11.875%
per annum.
 
NON-INVESTMENT GRADE REPURCHASE OFFER
 
    If an Investment Grade Locking Event has not occurred on or before August 1,
2006 (the "Put Date"), the Company will be required to offer to repurchase and
each Holder shall have the right, on or prior to the Put Payment Date (as
defined below), to require the Company to repurchase such Holder's Notes in
whole or in part pursuant to the offer described below (the "Non-Investment
Grade Repurchase Offer") at a purchase price equal to 100% of the aggregate
principal amount of such Notes plus accrued and unpaid interest, if any, to the
date of such repurchase. Notwithstanding the immediately preceding sentence, if
an Investment Grade Triggering Event occurs on or after the fifteenth day prior
to the Put Date (the "Delaying Event"), the Company shall not be required to
make the Non-Investment Grade Repurchase Offer until the fifteenth day following
the Delaying Event (the "Delayed Put Date"). If on the
 
                                       39
<PAGE>
Delayed Put Date, (i) an Investment Grade Locking Event occurs, the Company
shall not be required to make the Non-Investment Grade Repurchase Offer, or (ii)
if an Investment Grade Locking Event does not occur, the Company shall make the
Non-Investment Grade Repurchase Offer as described below.
 
    No later than the Put Date (or, if a Delaying Event has occurred, the
Delayed Put Date), the Company shall mail a notice to each Holder of Notes and
the Trustee in respect of the Non-Investment Grade Repurchase Offer (which
notice shall contain all instructions and materials necessary to enable such
Holders to tender Notes). All Notes tendered will be accepted for payment on a
date (the "Put Payment Date") which shall be no earlier than 30 days nor later
than 45 days from the date such notice is mailed.
 
    On the Put Payment Date, the Company shall (i) accept for payment all Notes
or portions thereof tendered pursuant to the Non-Investment Grade Repurchase
Offer, (ii) deposit with the Paying Agent money sufficient to pay the purchase
price of all Notes or portions thereof so tendered and accepted and (iii)
deliver or cause to be delivered to the Trustee Notes so accepted, together with
an Officer's Certificate stating the aggregate principal amount of the Notes or
portions thereof so accepted by the Company. The Paying Agent shall promptly
mail or deliver to the Holder of Notes so accepted payment in an amount equal to
the purchase price, and the Trustee shall promptly authenticate and mail or make
available for delivery to such Holder a new Note equal in principal amount to
any unpurchased portion of the Note surrendered. The Company will publicly
announce the results of the Non-Investment Grade Repurchase Offer.
 
CERTAIN NON-INVESTMENT GRADE COVENANTS
 
MAINTENANCE OF SUBORDINATED CAPITAL BASE
 
    The Indenture provides that until the occurrence of an Investment Grade
Locking Event, subject to the exception described in the fourth following
paragraph, in the event that the Company's Subordinated Capital Base is less
than $1 billion (the "Minimum Subordinated Capital Base") as at the end of each
of any two consecutive fiscal quarters (the last day of the second such fiscal
quarter, a "Deficiency Date"), then, with respect to the Notes, the Company
shall, no later than 60 days after the Deficiency Date (105 days if a Deficiency
Date is also the end of the Company's fiscal year), make an offer to all Holders
of Notes to purchase (a "Deficiency Offer") 10% of the principal amount of Notes
originally issued, or such lesser amount as may be Outstanding at the time such
Deficiency Offer is made (the "Deficiency Offer Amount"), at a purchase price
equal to 100% of principal amount, plus accrued and unpaid interest to the
Deficiency Payment Date (as defined below). Thereafter, semiannually the Company
shall make like Deficiency Offers for the then applicable Deficiency Offer
Amount of Notes until the Company's Subordinated Capital Base as at the end of
any subsequent fiscal quarter shall be equal to or greater than the Minimum
Subordinated Capital Base. Notwithstanding the foregoing, after any specified
Deficiency Date, the last day of any subsequent fiscal quarter shall not
constitute a Deficiency Date (giving rise to an additional obligation under the
first sentence of this paragraph) unless the Company's Subordinated Capital Base
was equal to or greater than the Minimum Subordinated Capital Base as at the end
of a fiscal quarter that followed such specified Deficiency Date and preceded
such subsequent quarter.
 
    Within 60 days (105 days if the Deficiency Date is also the end of the
Company's fiscal year) following a Deficiency Date, the Company shall mail a
notice to each Holder of Notes in respect of the Deficiency Offer (which notice
shall contain all instructions and materials necessary to enable such Holders to
tender Notes).
 
    Notes tendered pursuant to a Deficiency Offer will be accepted for payment,
in amounts as set forth below, on the date which shall be 20 Business Days from
the date such notice is mailed or, if acceptance for payment and payment is not
then lawful, on the earliest subsequent Business Day on which acceptance for
payment and payment is then lawful (a "Deficiency Payment Date").
 
                                       40
<PAGE>
    On a Deficiency Payment Date, the Company shall (i) accept for payment Notes
or portions thereof tendered pursuant to the Deficiency Offer in an aggregate
principal amount equal to the Deficiency Offer Amount or such lesser principal
amount of such Notes as shall have been tendered, (ii) deposit with the Paying
Agent money sufficient to pay the purchase price of all such Notes or portions
thereof so accepted, and (iii) deliver, or cause to be delivered to the Trustee,
Notes or portions thereof so accepted together with an Officer's Certificate
stating the Notes or portions thereof accepted by the Company. If the aggregate
principal amount of such Notes tendered exceeds the Deficiency Offer Amount, the
Company shall select the Notes to be purchased on a pro rata basis to the
nearest $1,000 of principal amount. The Paying Agent shall promptly mail or make
available for delivery to Holders of Notes so accepted payment in amounts equal
to the purchase prices therefor, and the Company shall execute and the Trustee
shall promptly authenticate and mail or make available for delivery to such
Holders new Notes equal in principal amounts to, any unpurchased portion of
Notes surrendered. The Company will publicly announce the results of the
Deficiency Offer.
 
    Notwithstanding the foregoing, in the event that (1) the making of a
Deficiency Offer by the Company or (2) the purchase of Notes by the Company in
respect of a Deficiency Offer would constitute a default (with the giving of
notice, the passage of time or both) with respect to any Specified Bank Debt at
the time outstanding, then, in lieu of the making of a Deficiency Offer in the
circumstances set forth above, (i) the interest rate on the Notes shall be reset
as of the first day of the second fiscal quarter following the Deficiency Date
(the "Reset Date") to a rate per annum (the "Reset Rate") specified above under
the heading "-- Principal, Maturity and Interest," (ii) on the first Interest
Payment Date following the Reset Date, the interest rate on the Notes as reset
on the Reset Date, shall increase by 50 basis points, and (iii) the interest
rate on the Notes shall further increase by an additional 50 basis points on
each succeeding Interest Payment Date; provided, however, that in no event shall
the interest rate on the Notes at any time exceed the Applicable Rate then in
effect by more than 200 basis points. The Reset Rate will be adjusted from time
to time, if necessary, to reflect any change in the Applicable Rate of the
Notes. If the Company's Subordinated Capital Base falls below $1 billion, it is
probable that the Company would also be in default under certain covenants
contained in the Credit Agreement.
 
    Once the interest rate on the Notes has been reset as set forth above, if
the Company's Subordinated Capital Base is equal to or greater than the Minimum
Subordinated Capital Base as of the last day of any fiscal quarter subsequent to
the Deficiency Date, interest on the Notes shall return, effective as of the
first day of the second following fiscal quarter, to the Applicable Rate in
effect on such day; provided, however, that the interest rate on the Notes shall
again be adjusted as set forth above if the Company's Subordinated Capital Base
shall thereafter be less than the Minimum Subordinated Capital Base as at the
last day of each of any two consecutive subsequent fiscal quarters and if the
making of a Deficiency Offer or the purchase of Notes by the Company in respect
of a Deficiency Offer would, at such time, constitute a default (with the giving
of notice, passage of time or both) with respect to any Specified Bank Debt at
the time outstanding.
 
    The Company shall notify the Trustee of the Reset Rate not later than two
Business Days after the Reset Date in the circumstances set forth in the second
preceding paragraph. Not later than five Business Days after the Trustee has
received such notice from the Company, the Trustee shall mail to each Holder of
Notes such notice setting forth the Reset Rate The Company shall notify the
Trustee and the Holders of Notes promptly when the interest rate on the Notes
returns to the Applicable Rate as set forth above.
 
    Notwithstanding the foregoing, the Indenture provides that this covenant
shall be of no further force or effect and shall cease to apply upon and after
the occurrence of an Investment Grade Locking Event.
 
LIMITATION ON FUTURE INCURRENCE OF INDEBTEDNESS
 
    The Indenture provides that until the occurrence of an Investment Grade
Locking Event the Company will not, and will not permit any Restricted
Subsidiary to, incur, create, assume, guarantee or in any other manner become
directly or indirectly liable with respect to or responsible for the payment of
any Indebtedness except: (1) Permitted Indebtedness; and (2) Indebtedness of the
Company if at the time
 
                                       41
<PAGE>
thereof and after giving effect thereto the Consolidated Interest Coverage Ratio
of the Company, on a pro forma basis for the then four most recent full fiscal
quarters, taken as a whole (giving effect to (i) such Indebtedness and (ii) the
effect on the Consolidated Cash Flow Available for Fixed Charges of the Company
for the then four most recent full fiscal quarters, taken as a whole, as a
result of any acquisition of a Person acquired by the Company or any Restricted
Subsidiary with the proceeds of such Indebtedness), would be greater than 1.75
to 1. Without limiting the foregoing, the Company shall not, and shall not
permit any Restricted Subsidiary to, guarantee, or in any other manner become
directly or indirectly liable with respect to or responsible for the payment of,
Indebtedness of any Unrestricted Subsidiary in an amount greater than, for all
guaranties and undertakings of responsibility by the Company and its Restricted
Subsidiaries, 20% of the aggregate amount of Indebtedness of such Unrestricted
Subsidiary.
 
    Notwithstanding the foregoing, the Indenture provides that this covenant
shall be of no further force or effect and shall cease to apply upon and after
the occurrence of an Investment Grade Locking Event.
 
RESTRICTIONS ON DIVIDENDS
 
    The Indenture provides that until the occurrence of an Investment Grade
Locking Event the Company will not, and will not permit any Subsidiary of the
Company to, directly or indirectly, (1) declare or pay any dividend or make any
distribution, in cash or otherwise, in respect of any shares of Capital Stock of
the Company or to the holders of Capital Stock of the Company as such (other
than dividends or distributions payable in shares of Capital Stock of the
Company (other than Redeemable Stock)) or (2) purchase, redeem or otherwise
acquire or retire for value any of the Capital Stock of the Company or options,
warrants or other rights to acquire any such Capital Stock, other than
acquisitions of Capital Stock or such options, warrants or other rights by any
Subsidiary of the Company from the Company (any such transaction included in
clause (1) or (2), a "Restricted Payment") if (i) at the time of such Restricted
Payment and after giving effect thereto, (a) an Event of Default shall have
occurred and be continuing or (b) the Consolidated Net Worth of the Company
shall be less than $750 million; or if (ii) after giving effect to such
Restricted Payment, the aggregate amount expended subsequent to November 1,
1991, for all such Restricted Payments (the amount of any Restricted Payment, if
other than cash, to be the fair market value of such payment as determined by
the Board of Directors of the Company, whose reasonable determination shall be
conclusive and evidenced by a Board Resolution) exceeds the algebraic sum of (w)
a number calculated as follows: (A) if the aggregate Consolidated Net Income of
the Company earned on a cumulative basis during the period subsequent to
September 30, 1991 through the end of the last fiscal quarter that is prior to
the declaration of any such dividend or distribution or the giving of notice of
such purchase, redemption or other acquisition or retirement and for which such
financial information is then available, is a positive number, then 100% of such
positive number, and (B) if the aggregate Consolidated Net Income of the Company
earned on a cumulative basis during the period subsequent to September 30, 1991
through the end of the last fiscal quarter that is prior to the declaration of
any such dividend or distribution or the giving of notice of such purchase,
redemption or other acquisition or retirement and for which such financial
information is then available, is a negative number, then 100% of such negative
number, (x) the aggregate net cash proceeds received by the Company from the
issuance and sale, other than to a Subsidiary of the Company, subsequent to
November 1, 1991, of Capital Stock (including Capital Stock issued upon the
conversion of, or in exchange for, securities other than Capital Stock and
options, warrants or other rights to acquire Capital Stock, but excluding
Redeemable Stock), (y) the aggregate net cash proceeds originally received by
the Company from the issuance and sale, other than to a Subsidiary of the
Company, of Indebtedness of the Company that is converted into Capital Stock of
the Company subsequent to November 1, 1991, and (z) $300 million; provided,
however, that the retirement of any shares of the Company's Capital Stock by
exchange for, or out of the proceeds of the substantially concurrent sale of,
other shares of Capital Stock of the Company other than Redeemable Stock shall
not constitute a Restricted Payment. If all of the conditions to the declaration
of a dividend or distribution that are described above are satisfied at the time
such dividend or distribution is declared, then such dividend or distribution
may be paid or made within sixty days after such declaration even if the payment
of such dividend, the making of such distribution or the declaration thereof
would not have been permitted at any time after such declaration.

    Notwithstanding the foregoing, the Indenture provides that this covenant
shall be of no further force or effect and shall cease to apply upon and after
the occurrence of an Investment Grade Locking Event.
 
LIMITATION ON FUTURE LIENS AND GUARANTIES
 
    Pursuant to the terms of the Indenture, until the occurrence of an
Investment Grade Locking Event if the Company or any Subsidiary of the Company
shall create, incur, assume or suffer to exist any Lien upon any of the assets
of the Company or a Subsidiary of the Company (whether such assets are owned at
November 1, 1991 or thereafter acquired) as security for (1) any Indebtedness or
other obligation (whether unconditional or contingent) of the Company that ranks
pari passu with the Notes or any Indebtedness or other obligation (whether
unconditional or contingent) of a Subsidiary of the Company, the Company will
secure or will cause such Subsidiary to guarantee and secure the Outstanding
Notes equally and ratably with (or, at the option of the Company, prior to) such
Indebtedness or other obligation, so long as such Indebtedness or other
obligation shall be so secured, or (2) any Subordinated Indebtedness, the
Company will secure the Outstanding Notes prior to such Subordinated
Indebtedness, so long as such Subordinated Indebtedness shall be so secured;
provided, however, that this covenant does not apply in the case of Permitted
Liens or Liens granted by any Unrestricted Subsidiary to secure Indebtedness or
other obligations of itself or of any Person other than the Company and its
Restricted Subsidiaries.
 
    Notwithstanding the foregoing, this covenant shall be of no further force or
effect and shall cease to apply upon and after the occurrence of an Investment
Grade Locking Event.
 
    In addition, pursuant to the terms of the Indenture, until the occurrence of
an Investment Grade Locking Event the Company will not guarantee the
Indebtedness of any Subsidiary of the Company and will not permit any such
Subsidiary to guarantee (i) any Indebtedness of the Company that ranks pari
passu with the Notes, (ii) any Indebtedness of a Subsidiary of the Company or
(iii) any Subordinated Indebtedness; provided, however, that this paragraph does
not apply to (1) any guaranty by a Subsidiary if such Subsidiary also guarantees
the Notes on a pari passu basis with respect to guaranties of Indebtedness
described in clauses (i) and (ii) and on a senior basis with respect to
guaranties of Indebtedness described in clause (iii); (2) any guaranty existing
on November 1, 1991 or any extension or renewal of such guaranty to the extent
such extension or renewal is for the same or a lesser amount; (3) any guaranty
which constitutes Indebtedness permitted by clause (v) or (vi) of the definition
of Permitted Indebtedness granted by a Person permitted to incur such
Indebtedness; (4) any guaranty by the Company of indebtedness of a Restricted
Subsidiary, provided that (A) incurrence of such Indebtedness of the Restricted
Subsidiary is not prohibited by the Indenture and (B) (x) such guaranty
constitutes Indebtedness of the Company incurred as Permitted Indebtedness
pursuant to clause (vii) or (viii) of the definition of Permitted Indebtedness
(it being understood that, for purposes of determining Permitted Indebtedness,
any such guaranty shall be deemed to constitute Indebtedness separate from, and,
in addition to, Indebtedness of a Restricted Subsidiary which is so guaranteed)
or (y) immediately prior to and (on a pro forma basis) after granting such
guaranty, the Company would be permitted to incur an additional dollar of
Indebtedness (not constituting Permitted Indebtedness) under the restrictions
described in "Limitation on Future Incurrence of Indebtedness" above; (5) any
guaranty by an Unrestricted Subsidiary of Indebtedness or other obligations of
any Person other than the Company and its Restricted Subsidiaries; (6) any
guaranty by the Company or any Subsidiary of Indebtedness or other obligations
constituting Indebtedness permitted by clause (i)(a) of the definition of
Permitted Indebtedness in a principal amount not exceeding the principal amount
outstanding or committed under the Credit Agreements (including any letter of
credit facility, but without duplication with respect to commitments for loans
the use of proceeds of which is restricted to repayment of other Indebtedness
under the Credit Agreements) as of November 1, 1991, plus $250 million and less
the proceeds from the sale of all Indebtedness under the 1991 Indenture issued
from time to time that are applied to repay Indebtedness under the Credit
Agreements); (7) any guaranty by the Company of Indebtedness of any Restricted
Subsidiary outstanding on November 1, 1991 which is not subordinated to any
Indebtedness of such Restricted Subsidiary, and any renewal extension or
refinancing of such Indebtedness permitted by the Indenture; (8) any guaranty by
the Company of Indebtedness of any Restricted Subsidiary that is
 
                                       43
<PAGE>
organized under the laws of a jurisdiction other than the United States or any
subdivision thereof, provided that the incurrence of such Indebtedness of such
Restricted Subsidiary is not prohibited by the Indenture; (9) any guaranty by a
Restricted Subsidiary that is organized under the laws of a jurisdiction other
than the United States or any subdivision thereof of the Indebtedness of any of
its Subsidiaries that is a Restricted Subsidiary and that is organized under the
laws of a jurisdiction other than the United States or any subdivision thereof,
provided that incurrence of such Indebtedness of such Restricted Subsidiary is
not prohibited by the Indenture; (10) any guaranty by the Company or a
Subsidiary of the Company of Indebtedness or other obligations in a principal
amount not exceeding $250,000; (11) any guaranty in the form of an endorsement
of negotiable instruments for deposit or collection and similar transactions;
(12) any guaranty arising under or in connection with performance bonds,
indemnity bonds, surety bonds or commercial letters of credit not exceeding $25
million in aggregate principal amount from time to time outstanding; (13) any
guaranty by a Subsidiary of the Company of Indebtedness or other obligations of
another Subsidiary in effect at the time of such guarantor becoming a Subsidiary
and not created in contemplation thereof; or (14) any guaranty by the Company or
a Restricted Subsidiary of any Interest Swap Obligation, Currency Agreement or
Commodities Agreement relating to Indebtedness that is guaranteed pursuant to
another clause of this paragraph.
 
    Notwithstanding the foregoing, this covenant shall be of no further force or
effect and shall cease to apply upon and after the occurrence of an Investment
Grade Locking Event.
 
LIMITATION ON ASSET DISPOSITIONS
 
    The Indenture provides that until the occurrence of an Investment Grade
Locking Event (i) the Company will not, and will not permit any Restricted
Subsidiary to, make any Asset Disposition unless the Company (or the Restricted
Subsidiary, as the case may be) receives consideration at the time of such Asset
Disposition at least equal to the fair market value for the assets sold or
otherwise disposed of (which shall be determined in good faith (x) in the case
of dispositions of assets having a fair market value of $10 million or more, by
the Board of Directors of the Company, whose reasonable determination shall be
conclusive and evidenced by a Board Resolution, or (y) in the case of
dispositions of assets having a fair market value of less than $10 million but
not less than $5 million, an Officer of the Company, whose reasonable
determination shall be conclusive and evidenced by a certificate of such
Officer) and (ii) the Company will apply the aggregate net proceeds in excess of
$300 million received by the Company or any Restricted Subsidiary from all Asset
Dispositions occurring subsequent to November 1, 1991 (but excluding for
purposes of this clause (ii), whether before or after the receipt of net
proceeds in excess of $300 million, (1) the net proceeds of any Asset
Disposition or series of related Asset Dispositions where the net proceeds are
less than $5 million and (2) the first $25 million of net proceeds in each
fiscal year without taking into account any amount excluded pursuant to (1)) as
follows: (a) to the payment or prepayment of any Senior Indebtedness within six
months of such Asset Disposition, or (b) to investment in the business of the
Company and its Restricted Subsidiaries (including, without limitation, by
acquiring equity, other than Redeemable Stock, of the transferee of such Asset
Disposition) within six months of such Asset Disposition or, if such investment
is with respect to a project to be completed within a period greater than six
months from such Asset Disposition, then within the period of time necessary to
complete such project; provided, however, that (x) in the case of applications
contemplated by clause (b), the Board of Directors has, within such six-month
period, adopted in good faith a resolution committing such excess proceeds to
such investment, (y) except as provided in the next sentence, none of such
excess proceeds shall be used to make any Restricted Payment or any payment in
respect of Subordinated Indebtedness and (z) to the extent not applied in
accordance with clauses (a) or (b) above, or if after being so applied there
remain excess net proceeds in an amount greater than $10 million, the Company
shall make a pro rata offer to all Holders to purchase Notes at 100% of
principal amount, plus accrued and unpaid interest to the Asset Disposition
Payment Date (as defined below), up to an aggregate principal amount equal to
such excess net proceeds (the "Asset Disposition Offer Amount"). If after being
applied in accordance with clauses (a), (b) and (z) above there remain excess
net proceeds, the Company will apply such excess net proceeds to the general
corporate purposes of the Company or any Subsidiary of the Company.
 
                                       44
<PAGE>
    Notwithstanding the foregoing, to the extent the Company or any of its
Restricted Subsidiaries receives securities or other non-cash property or assets
as proceeds of an Asset Disposition (other than equity in the transferee not
constituting Redeemable Stock), the Company shall not be required to make any
application required by the preceding paragraph until it receives cash proceeds
from a sale, repayment, exchange, redemption or retirement of or extraordinary
dividend or return of capital on such non-cash property, except that if and to
the extent the sum of all cash proceeds plus the fair market value of equity
(other than Redeemable Stock) in the transferee of such Asset Disposition
received at the time of such Asset Disposition is less than 70% of the fair
market value of the total proceeds of such Asset Disposition (with such fair
market value determined and evidenced in the same manner as stated in clause (i)
of the preceding paragraph), the amount of such deficiency (the "Deficiency
Amount") shall be applied as required by the preceding paragraph as if received
at the time of the Asset Disposition. Any amounts deferred pursuant to the
preceding sentence shall be applied in accordance with the preceding paragraph
when cash proceeds are thereafter received from a sale, repayment, exchange,
redemption or retirement of or extraordinary dividend or return of capital on
such non-cash property, provided, however, that the Company shall not be
required to apply with respect to any equity interest in a transferee an amount
exceeding the fair market value attributable to such equity interest at the time
of the Asset Disposition; and provided, further, that if a Deficiency Amount was
applied pursuant to the exception contained in the preceding sentence, then once
the cumulative amount of applications made pursuant to the preceding paragraph
and this paragraph (including any Deficiency Amounts) equals 100% of the fair
market value of the total proceeds of the Asset Disposition at the time of such
Asset Disposition, cash proceeds thereafter received from a sale, repayment,
exchange, redemption or retirement of or extraordinary dividend or return of
capital on such non-cash property shall not be required to be applied in
accordance with the preceding paragraph except to the extent such cash proceeds
exceed the Deficiency Amount.
 
    An offer to purchase Notes required to be made pursuant to this covenant is
an "Asset Disposition Offer" and the date on which the purchase of Notes
relating to any such Asset Disposition Offer is to be made is an "Asset
Disposition Payment Date."
 
    Notice of an Asset Disposition Offer shall be mailed on behalf of the
Company by the Trustee to all Holders of Notes at their last registered
addresses not less than 30 days nor more than 60 days before the Asset
Disposition Payment Date, which shall be a date not more than 210 days after the
Asset Disposition giving rise to such Asset Disposition Offer. The Asset
Disposition Offer shall remain open from the time of the mailing of such notice
until not more than five Business Days before the Asset Disposition Payment
Date.
 
    On the Asset Disposition Payment Date, the Company shall (i) accept for
payment Notes or portions thereof tendered pursuant to the Asset Disposition
Offer in an aggregate principal amount equal to the Asset Disposition Offer
Amount or such lesser amount of Notes as shall have been tendered, (ii) deposit
with the Paying Agent money sufficient to pay the purchase price of all Notes or
portions thereof so accepted, and (iii) deliver or cause to be delivered to the
Trustee, Notes so accepted together with an Officer's Certificate stating the
Notes or portions thereof accepted by the Company. If the aggregate principal
amount of Notes tendered exceeds the Asset Disposition Offer Amount, the Company
shall select the Notes to be purchased on a pro rata basis to the nearest $1,000
of principal amount. The Paying Agent shall promptly mail or deliver to Holders
of Notes so accepted payment in an amount equal to the purchase price, and the
Company shall execute and the Trustee shall promptly authenticate and mail or
make available for delivery to such Holders a new Note equal in principal amount
to any unpurchased portion of the Note surrendered. The Company will publicly
announce the results of the Asset Disposition Offer.
 
    The Company shall not make an "Asset Disposition Offer" (as defined)
required under the 1991 Indenture or the 1994 Indentures in connection with a
disposition of assets other than the Collateral (as defined in the First
Mortgage Note Indenture) unless the Company shall have made an Asset Disposition
Offer in respect of the Notes (and certain other Senior Indebtedness in
accordance with the following sentence) on a pro rata basis (in an aggregate
amount equal to the amount to be offered pursuant to the
 
                                       45
<PAGE>
Asset Disposition Offer under the 1991 Indenture and the 1994 Indentures (and in
accordance with Section 1009(g) of the 1994 Indentures)), the closing date of
which is prior to six months after the asset disposition triggering the
obligations of the Company under the 1991 Indenture. Notwithstanding the
previous sentence, if on or after the date of the Indenture, the Company issues
any Senior Indebtedness (including the Notes) containing a requirement that an
offer be made to repurchase such Senior Indebtedness under the same
circumstances and in the same manner (including the prescribed time periods
hereof) provided herein, then (i) the Company may apply the Asset Disposition
Offer Amount (before any adjustment pursuant to this sentence) to the pro rata
purchase of Notes tendered under the Indenture and the Senior Indebtedness
tendered thereunder and (ii) the Asset Disposition Offer Amount available to
repurchase the Notes shall be reduced by the amount applied to the purchase of
such Senior Indebtedness; provided, however, that this sentence shall only apply
to Senior Indebtedness issued on or after the Issue Date that explicitly permits
the pro rata purchase of Notes as described in the Indenture and refers to the
"Limitation on Asset Dispositions" covenant and any Indebtedness outstanding at
the Issue Date that is amended to explicitly permit the pro rata purchase of
Notes as described therein and refers to the "Limitation on Asset Dispositions"
covenant.
 
    In the event that the First Mortgage Notes are refinanced through a public
or private offering of Indebtedness constituting debt securities and the amount
of such refinancing Indebtedness is no greater than the principal amount of the
First Mortgage Notes Outstanding as of the date of such refinancing, the Company
need not comply with the first paragraph of this covenant in respect of an Asset
Disposition involving the collateral securing such Indebtedness (other than
collateral granted in respect of such Indebtedness pursuant to a negative pledge
or similar provision contained in the indenture or similar instrument relating
to such Indebtedness) to the extent that such compliance would constitute a
default under such indenture or similar instrument.
 
    Notwithstanding the foregoing, this covenant shall be of no further force or
effect and shall cease to apply upon and after the occurrence of an Investment
Grade Locking Event.
 
RESTRICTIONS ON MERGERS AND CONSOLIDATIONS AND SALES OF ASSETS
 
    The Indenture provides that until the occurrence of an Investment Grade
Locking Event the Company shall not consolidate with, or merge with or into any
other corporation (whether or not the Company shall be the surviving
corporation), or sell, assign, transfer or lease all or substantially all of its
properties and assets as an entirety or substantially as an entirety to any
Person or group of affiliated Persons, in one transaction or a series of related
transactions, unless: (1) either the Company shall be the continuing Person or
the Person (if other than the Company) formed by such consolidation or with
which or into which the Company is merged or the Person (or group of affiliated
Persons) to which all or substantially all the properties and assets of the
Company are sold, assigned, transferred or leased is a corporation (or
constitute corporations) organized under the laws of the United States of
America or any State thereof or the District of Columbia and expressly assumes,
by an indenture supplemental to the Indenture, all the obligations of the
Company under the Notes and the Indenture; (2) immediately before and after
giving effect to such transaction or series of related transactions, no Event of
Default, and no Default, shall have occurred and be continuing; (3) immediately
after giving effect to such transaction or series of related transactions, on a
pro forma basis, but prior to any purchase accounting adjustments resulting from
the transaction or series of related transactions, the Consolidated Net Worth of
the Company (or of the surviving, consolidated or transferee entity if the
Company is not continuing, treating such entity as the Company for purposes of
determining Consolidated Net Worth) shall be at least equal to the Consolidated
Net Worth of the Company immediately before such transaction; (4) immediately
after giving effect to such transaction or series of related transactions, the
Company (or the surviving, consolidated or transferee entity if the Company is
not continuing, but treating such entity as the Company for purposes of making
such determination) would be permitted to incur an additional dollar of
Indebtedness (not constituting Permitted Indebtedness) immediately prior to such
transaction or series of related transactions, under the covenant contained in
the Indenture restricting the incurrence of Indebtedness; provided, however,
that this clause (4) shall be inapplicable if (a) such transaction or series of
related transactions, would result in the occurrence of a Change of Control or
(b) immediately
 
                                       46
<PAGE>
prior to giving effect to such transaction or series of related transactions,
the Company would not be permitted to incur an additional dollar of Indebtedness
(not constituting Permitted Indebtedness) under such covenant, and immediately
after giving effect to such transaction or series of related transactions, on a
pro forma basis, but prior to any purchase accounting adjustments resulting from
the transaction or series of related transactions, the Consolidated Interest
Coverage Ratio of the Company (or the surviving, consolidated or transferee
entity if the Company is not continuing, treating such entity as the Company for
purposes of determining the Consolidated Interest Coverage Ratio) shall be at
least equal to the Consolidated Interest Coverage Ratio of the Company
immediately before such transaction or series of related transactions; and (5)
the Company shall have delivered to the Trustee an Officer's Certificate and an
Opinion of Counsel, each stating that such consolidation, merger or transfer and
such supplemental indenture comply with the Indenture and that all conditions
precedent to the consummation of the transaction or series of related
transactions under the Indenture have been met. Notwithstanding the foregoing,
if clause (4) of the preceding sentence is inapplicable by reason of clause (b)
of the proviso thereto, and at the date three months after the consummation of
such transaction or series of related transactions, the rating ascribed to the
Notes by S&P or Moody's shall be lower than the rating ascribed to the Notes
prior to the public announcement of such transaction, then the Company shall
make an offer for the Notes at the same price and following the same procedures
and obligations as required with respect to a Change of Control (as if such date
three months after the giving effect to such transaction were the "Change of
Control Date"). See "-- LIMITATION ON FUTURE INCURRENCE OF INDEBTEDNESS" above
and "-- Change of Control" below. Notwithstanding the foregoing, clauses (3) and
(4) shall be of no further force or effect and shall cease to apply upon and
after the occurrence of an Investment Grade Locking Event.
 
    If, upon any consolidation or merger, or upon any sale, assignment, transfer
or lease, as provided in the preceding paragraph, any material property of the
Company or any Restricted Subsidiary or any shares of Capital Stock or
Indebtedness of any Restricted Subsidiary, owned immediately prior thereto,
would thereupon become subject to any Lien securing any indebtedness for
borrowed money of, or guaranteed by, such other corporation or Person (other
than any Permitted Lien), the Company, prior to such consolidation, merger,
sale, assignment, transfer or lease, will, by an indenture supplemental to the
Indenture, secure the due and punctual payment of the principal of, and premium,
if any, and interest on the Notes then Outstanding (together with, if the
Company shall so determine, any other indebtedness of, or guaranteed by, the
Company or any Restricted Subsidiary and then existing or thereafter created)
equally and ratably with (or, at the option of the Company, prior to) the
Indebtedness secured by such Lien. Notwithstanding the foregoing, this covenant
shall be of no further force or effect and shall cease to apply upon and after
the occurrence of an Investment Grade Locking Event.
 
CERTAIN INVESTMENT GRADE COVENANTS
 
RESTRICTIONS ON SECURED INDEBTEDNESS
 
    Upon and after the occurrence of an Investment Grade Locking Event, if the
Company or any Restricted Subsidiary shall incur, issue, assume or guarantee any
Indebtedness secured by a Lien on any Principal Property of the Company or any
Restricted Subsidiary or on any share of stock or Indebtedness of any Restricted
Subsidiary, the Company will secure or cause such Restricted Subsidiary to
secure the Notes equally and ratably with (or, at the Company's option, prior
to) such secured Indebtedness so long as such Indebtedness shall be so secured,
unless the aggregate amount of all such secured Indebtedness, together with all
Attributable Indebtedness of the Company and its Restricted Subsidiaries with
respect to any sale and leaseback transactions involving Principal Properties
(with the exception of such transactions which are excluded as described in
clauses (i) through (v) under "-- RESTRICTIONS ON SALES AND LEASEBACKS" below),
would not exceed 10% of Consolidated Net Tangible Assets. The above restriction
does not apply to, and there will be excluded from secured Indebtedness in any
computation under such restriction, Indebtedness secured by: (i) Liens on
property of, or on any share of stock or Indebtedness of, any corporation
existing at the time such corporation becomes a Restricted Subsidiary and Liens
on any property acquired from a corporation which is merged with or into the
Company or a Subsidiary; (ii) Liens in favor of the Company or a Restricted
Subsidiary; (iii) Liens
 
                                       47
<PAGE>
in favor of governmental bodies to secure progress, advance or other payments;
(iv) Liens upon any property acquired after the date of the Indenture, securing
the purchase price thereof or created or incurred simultaneously with (or within
180 days after) such acquisition to finance the acquisition of such property or
existing on such property at the time of such acquisition, or Liens on
improvements after such date, in each case subject to certain conditions and
provided that the principal amount of the obligation or indebtedness secured by
such Lien shall not exceed 100% of the cost or fair value (as determined in good
faith by the Company), whichever shall be lower, of the property at the time of
the acquisition, construction or improvement thereof; (v) Liens securing
industrial revenue or pollution control bonds; (vi) Liens on timberlands or in
connection with arrangements under which the Company or any Restricted
Subsidiary is obligated to cut or pay for timber; (vii) Liens arising out of any
final judgment for the payment of money aggregating not in excess of $25 million
or Liens arising out of any judgments which are being contested in good faith;
(viii) Permitted Liens in existence on the date of the Investment Grade Locking
Event; or (ix) any extension, renewal, or replacement of any Lien referred to in
the foregoing clauses (i) through (viii) inclusive.
 
RESTRICTIONS ON SALES AND LEASEBACKS
 
    Upon and after the occurrence of an Investment Grade Locking Event, neither
the Company nor any Restricted Subsidiary may enter into any sale and leaseback
transaction involving any Principal Property, unless the aggregate amount of all
Attributable Indebtedness of the Company and its Restricted Subsidiaries with
respect to such transaction plus all secured Indebtedness (with the exception of
secured Indebtedness which is excluded as described in clauses (i) through (ix)
under "-- RESTRICTIONS ON SECURED INDEBTEDNESS" above) would not exceed 10% of
Consolidated Net Tangible Assets. This restriction does not apply to, and there
shall be excluded from Attributable Indebtedness in any computation under such
restriction, any sale and leaseback transaction if: (i) the lease is for a
period, including renewal rights, not in excess of three years; (ii) the sale of
the Principal Property is made within 180 days after its acquisition,
construction or improvement; (iii) the lease secures or relates to industrial
revenue or pollution control bonds; (iv) the transaction is between the Company
and a Restricted Subsidiary or between Restricted Subsidiaries; or (v) the
Company or such Restricted Subsidiary, within 180 days after the sale is
completed, applies to the retirement of Indebtedness of the Company or a
Restricted Subsidiary, or to the purchase of other property which will
constitute Principal Property, an amount not less than the greater of (1) the
net proceeds of the sale of the Principal Property leased or (2) the fair market
value (as determined by the Company in good faith) of the Principal Property
leased. The amount to be applied to the retirement of Indebtedness shall be
reduced by (x) the principal amount of any debentures or notes (including the
Notes) of the Company or a Restricted Subsidiary surrendered within 180 days
after such sale to the applicable trustee for retirement and cancellation, (y)
the principal amount of Indebtedness, other than the items referred to in the
preceding clause (x), voluntarily retired by the Company or a Restricted
Subsidiary within 180 days after such sale and (z) associated transaction
expenses.
 
CHANGE OF CONTROL
 
    Upon the occurrence of a Change of Control (the "Change of Control Date")
and subject to the requirements of the next succeeding sentence, each Holder
shall have the right to require that the Company repurchase such Holder's Notes
in whole or in part pursuant to the offer described below (the "Change of
Control Offer") at a purchase price equal to 101% of the aggregate principal
amount of such Notes plus accrued and unpaid interest, if any, to the date of
such repurchase. If such repurchase would constitute an event of default under
Specified Bank Debt, then, prior to giving the notice to Holders provided below,
the Indenture requires the Company to (1) repay in full in cash such Specified
Bank Debt or (2) obtain the requisite consent of holders of such Specified Bank
Debt to permit the repurchase of Notes without giving rise to an event of
default under such Specified Bank Debt.
 
    Promptly upon satisfaction of either one of the obligations, if then
applicable, described above, Company shall mail a notice to each Holder of Notes
and the Trustee in respect of the Change of Control Offer (which notice shall
contain all instructions and materials necessary to enable such Holders to
tender Notes). All Notes tendered will be accepted for payment on a date (the
"Change of Control
 
                                       48
<PAGE>
Payment Date") which shall be no earlier than 30 days nor later than 40 days
from the date such notice is mailed, but in any event prior to the date on which
any Subordinated Indebtedness is paid pursuant to the terms of a provision
similar to the Change of Control Offer covenant.
 
    On the Change of Control Payment Date, the Company shall (i) accept for
payment Notes or portions thereof tendered pursuant to the Change of Control
Offer, (ii) deposit with the Paying Agent money sufficient to pay the purchase
price of all Notes or portions thereof so accepted and (iii) deliver or cause to
be delivered to the Trustee Notes so accepted, together with an Officer's
Certificate stating the aggregate principal amount of the Notes or portions
thereof so accepted by the Company. The Paying Agent shall promptly mail or
deliver to the Holder of Notes so accepted payment in an amount equal to the
purchase price, and the Trustee shall promptly authenticate and mail or make
available for delivery to such Holder a new Note and equal in principal amount
to any unpurchased portion of the Note surrendered. The Company will publicly
announce the results of the Change of Control Offer.
 
    Whether a Change of Control has occurred depends entirely on the
accumulation of common stock of the Company and on certain changes in the
composition of the Company's Board of Directors. As a result, the Company can
enter into certain highly leveraged transactions, including certain
recapitalizations, mergers or stock repurchases, that would not result in the
application of the Change of Control provisions. Because the definitions of
"Change of Control" and "Acquiring Person" exclude the Company, any Subsidiary
of the Company and certain members of the Stone family, certain transactions in
which such entities and persons participate as beneficial owners of Common Stock
(including, among others, a leveraged buyout or recapitalization) would not
constitute a Change of Control.
 
EVENTS OF DEFAULT AND NOTICE THEREOF
 
    The following are Events of Default under the Indenture: (1) failure to pay
interest on any Note when due, continued for 30 days; (2) failure to pay the
principal of (or premium, if any, on) any Note when due and payable at Maturity,
upon redemption, upon repurchase pursuant to a Deficiency Offer as described
under "-- MAINTENANCE OF SUBORDINATED CAPITAL BASE" above, pursuant to an Asset
Disposition Offer described under "-- LIMITATION ON ASSET DISPOSITIONS," a
Change of Control Offer as described under
"-- Change of Control," a Non-Investment Grade Repurchase Offer as described
under "-- Non-Investment Grade Repurchase Offer" above or otherwise; (3) failure
to observe or perform any other applicable covenant, warranty or agreement
contained in the Notes or in the Indenture continued for a period of 60 days
after notice has been given to the Company by the Trustee or Holders of at least
25% in aggregate principal amount of the Outstanding Notes; (4) failure to pay
at final maturity, or acceleration of, Indebtedness of the Company having an
aggregate principal amount of not less than $25 million (or, if less, the least
amount contained in any similar provision of an instrument governing any
outstanding Subordinated Indebtedness of the Company, but in no event less than
$10 million), unless cured within 15 days after notice has been given to the
Company by the Trustee or Holders of at least 25% in aggregate principal amount
of the Outstanding Notes; (5) the entering against the Company of one or more
judgments or decrees involving an aggregate liability of $25 million or more
unless vacated, discharged, satisfied or stayed within 30 days of the entering
of such judgments or decrees; and (6) certain events of bankruptcy, insolvency
or reorganization relating to the Company.
 
    The Indenture provides that the Trustee shall, within 30 days after the
occurrence of any Default or Event of Default give the Holders of Notes notice

Notes upon the conditions provided in the Indenture.

series, other modification in the terms of payment of the principal of or
interest on any Securities of any series or reduction of the percentage required
for modification, will be effective against any Holder of any Outstanding
Securities of any series affected thereby without his consent.
 
    The Holders of at least a majority in principal amount of the Outstanding
Securities of any series may on behalf of the Holders of all Securities of that
series waive compliance by the Company with certain restrictive covenants of the
Indenture. The Holders of at least a majority in principal amount of the
Outstanding Securities of any series may on behalf of the Holders of all
Securities of that series waive any past Event of Default or Default under the
Indenture, except an Event of Default or a Default in the payment of the
principal of or premium, if any, or any interest on any Securities of that
series or in respect of a provision which under the Indenture cannot be modified

                 UNITED STATES FEDERAL INCOME TAX CONSEQUENCES
 
    The following summary describes the material United States federal income
tax consequences of the purchase, ownership and disposition of Notes to
beneficial owners purchasing Notes at their original issuance ("holders"). This
summary is based on the Internal Revenue Code of 1986, as amended (the "Code"),
legislative history, administrative pronouncements, judicial decisions and
final, temporary and proposed Treasury Regulations, changes to any of which
subsequent to the date of this Prospectus may affect the tax consequences
described herein. This summary does not address all of the tax consequences that
might be relevant to the holder in light of the holder's particular
circumstances or to holders subject to special rules. This summary assumes that
holders will hold the Notes as capital assets within the meaning of Section 1221
of the Code. This summary does not address any tax consequences to a holder who
or which is, for United States federal income tax purposes, a non-resident alien
individual, a foreign corporation, a foreign partnership or a foreign estate or
trust. Furthermore, this summary does not describe any aspect of the tax laws of
any state, local or foreign jurisdiction.
 
THE EXCHANGE
 
    An exchange of Old Notes for New Notes pursuant to the Exchange Offer should
not be treated as a sale, exchange or other taxable event for federal income tax
purposes because the New Notes should not be considered to differ materially in
kind or extent from the Old Notes. As a result, no material federal income tax
consequences should result from an exchange of Old Notes for New Notes pursuant
to the Exchange Offer.
 
    For federal income tax purposes, a New Note received by a beneficial owner
of an Old Note should be treated as a continuation of the Old Note in the hands
of such owner.
 
RECOGNITION OF INTEREST INCOME
 
    On June 11, 1996, the Internal Revenue Service issued final Treasury
Regulations governing the treatment of debt instruments issued on or after
August 13, 1996 that provide for one or more contingent
 
                                       64
<PAGE>
payments. Although the interest payments on the Notes will be treated as
contingent payments, the Old Notes were issued prior to August 13, 1996 and
therefore the final Treasury Regulations will not apply to the Notes. With
respect to debt instruments issued prior to August 13, 1996, the preamble to the
final Treasury Regulations states that a taxpayer, which would include the
Company or a holder of Notes, may use any reasonable method to account for
contingent payments.
 
    Under general principles of federal income tax law, interest on the Notes
may be taken into income by a holder that uses the cash method of accounting
when actually or constructively received, and may be taken into income by a
holder that uses an accrual method of accounting when the right to receive such
interest is fixed and the amount thereof is determinable with reasonable
accuracy. Alternatively, the preamble to the final Treasury Regulations states
that a reasonable method would include the method set forth in the proposed
Treasury Regulations which have been finalized through the issuance of the final
Treasury Regulations. Under those proposed Treasury Regulations, a payment
schedule must be projected for the contingent payment debt instrument and
holders generally must recognize interest income on a constant-yield basis based
on the projected schedule, with certain adjustments if payments are not made in
accordance with such schedule. The method set forth in the proposed Treasury
Regulations might result in the inclusion of interest in income earlier or later
than under the general principles of federal income tax law described above
depending upon the projected payment schedule and might result in the inclusion
in income before the receipt of cash attributable thereto. Under the proposed
Treasury Regulations, certain amounts realized upon disposition of a Note which
would otherwise be treated as capital gain or loss may be recharacterized as
interest income or ordinary loss.
 
    The Company believes the general principles of federal income tax law
discussed above constitute a reasonable method, and consequently the Company
intends to accrue interest expense on the Notes and to provide tax reporting
information to holders and the Internal Revenue Service, consistent with these
principles.
 
SALE, EXCHANGE OR RETIREMENT OF NOTES
 
    A holder generally recognizes gain or loss upon the sale, exchange or
retirement of a Note equal to the difference between the amount realized upon
such sale, exchange or retirement (excluding any amount attributable to accrued
but unpaid interest) and the holder's adjusted basis in the Note. In general, a
holder's tax basis in the Note will be equal to the holder's cost for the Note
decreased by any principal payments on the Note. To the extent attributable to
accrued but unpaid interest, the amount realized by the holder will be treated
as payment of interest. Except as noted above under "-- Recognition of Interest
Income", any gain or loss generally will be capital gain or loss and will be
long-term capital gain or loss if the Notes have been held for more than one
year at the time of such sale, exchange or retirement.
 
BACKUP WITHHOLDING AND INFORMATION REPORTING
 
    Information reporting requirements apply to interest and principal payments
made to, and to the proceeds of sales before maturity by, certain non-corporate
holders. In addition, a 31% backup withholding tax applies if the non-corporate
holder fails to provide certain identifying information (such as the holder's
taxpayer identification number) in the required manner. Backup withholding does
not apply with respect to payments made to certain exempt recipients, such as
corporations and tax-exempt organizations. Any amounts withheld from a payment
to a holder under the backup withholding rules are allowed as a refund or a
credit against such holder's United States federal income tax, provided that the
required information is furnished to the Internal Revenue Service.
 
                                       65
<PAGE>
    THE FOREGOING DISCUSSION OF CERTAIN FEDERAL INCOME TAX CONSEQUENCES IS NOT
TAX ADVICE. ACCORDINGLY, EACH PERSON CONSIDERING THE ACQUISITION OF NEW NOTES
SHOULD CONSULT A TAX ADVISOR WITH RESPECT TO THE TAX CONSEQUENCES TO HIM, HER OR
IT OF THE ACQUISITION, OWNERSHIP AND DISPOSITION OF THE NEW NOTES, INCLUDING THE
APPLICABILITY AND EFFECT OF STATE, LOCAL AND FOREIGN TAX LAWS AND OF CHANGES IN
APPLICABLE TAX LAWS.
 
                              PLAN OF DISTRIBUTION
 
    Prior to the Exchange Offer, there has been no market for any of the New
Notes. The New Notes have been approved for listing on the NYSE. The Old Notes
are eligible for trading in the Private Offerings, Resales and Trading through
Automatic Linkages ("PORTAL") market. There can be no assurance that an active
trading market will develop for, or as to the liquidity of, any of the Notes.
 
    With respect to resales of New Notes, based on an interpretation by the
staff of the Commission set forth in no-action letters issued to third parties,
the Company believes that any holder or beneficial owner (other than a person
that is an affiliate of the Company within the meaning of Rule 405 under the
Securities Act or a "broker" or "dealer" registered under the Exchange Act) who
exchanges Old Notes for New Notes in the ordinary course of business and who is
not participating, does not intend to participate, and has no arrangement or
understanding with any person to participate, in the distribution of the New
Notes, will be allowed to resell the New Notes to the public without further
registration under the Securities Act and without delivering to the purchasers
of the New Notes a prospectus that satisfies the requirements of Section 10
thereof. However, if any holder or beneficial owner acquires New Notes in the
Exchange Offer for the purpose of distributing or participating in a
distribution of the New Notes, such holder or beneficial owner cannot rely on
the position of the staff of the Commission enunciated in Exxon Capital Holdings
Corporation (available May 13, 1988) or similar no-action letters or any similar
interpretive letters and must comply with the registration and prospectus
delivery requirements of the Securities Act in connection with a secondary
resale transaction, unless an exemption from registration is otherwise
available.
 
    As contemplated by the above no-action letters and the Registration Rights
Agreement, each holder accepting the Exchange Offer is required to represent to
the Company in the Letter of Transmittal that (i) the New Notes to be acquired
by the holder and any Beneficial Owners of Old Notes in connection with the
Exchange Offer are being acquired in the ordinary course of business of the
holder and any Beneficial Owners, (ii) the holder and each Beneficial Owner are
not engaging, do not intend to engage and have no arrangements or understanding
with any person to participate in the distribution of the New Notes, (iii) the
holder and each Beneficial Owner acknowledge and agree that any person
participating in the Exchange Offer for the purpose of distributing the New
Notes must comply with the registration and prospectus delivery requirements of
the Securities Act in connection with a secondary resale transaction of the New
Notes acquired by such person and cannot rely on the position of the Staff of
the Commission set forth in no-action letters that are discussed herein above,
(iv) the holder and each Beneficial Owner understands that a secondary resale
transaction described in clause (iii) above should be covered by an effective
registration statement containing the selling securityholder information
required by Item 507 or 508, as applicable, of Regulation S-K of the Commission,
and (v) neither the holder nor any Beneficial Owner(s) is an "affiliate," as
defined under Rule 405 of the Securities Act, of the Company except as otherwise
disclosed to the Company in writing.
 
    Any broker or dealer registered under the Exchange Act (each a
"Broker-Dealer") who holds Old Notes that were acquired for its own account as a
result of market-making activities or other trading activities (other than Old
Notes acquired directly from the Company or any affiliate of the Company) may
exchange such Old Notes for New Notes pursuant to the Exchange Offer; however,
such Broker-Dealer may be deemed an underwriter within the meaning of the
Securities Act and, therefore, must deliver a prospectus meeting the
requirements of the Securities Act in connection with any resales of the New
Notes received by it in the Exchange Offer, which prospectus delivery
requirement may be satisfied by the delivery by such Broker-Dealer of this
Prospectus. Any Broker-Dealer participating in the Exchange
 
                                       66
<PAGE>
Offer will be required to acknowledge that it will deliver a prospectus meeting
the requirements of the Securities Act in connection with any resales of New
Notes received by it in the Exchange Offer. However only Broker-Dealers who
exchange Old Notes that were acquired for their own account as a result of
market-making activities or other trading activities (other than Old Notes
acquired directly from the Company or any affiliate of the Company), may use
this Prospectus to satisfy the prospectus delivery requirements of the
Securities Act. The delivery by a Broker-Dealer of a prospectus in connection
with resales of New Notes shall not be deemed to be an admission by such
Broker-Dealer that it is an underwriter within the meaning of the Securities
Act.
 
                                 LEGAL MATTERS
 
    Certain legal matters will be passed upon for the Company by Leslie T.
Lederer, Vice President, Secretary and Counsel of the Company (who owns Common
Stock of the Company).
 
                                    EXPERTS
 
    The financial statements incorporated in this Prospectus by reference to the
Company's Annual Report on Form 10-K for the year ended December 31, 1995 have
been so incorporated in reliance on the report of Price Waterhouse LLP,
independent accountants, given on the authority of said firm as experts in
auditing and accounting.
