This prospectus supplement relates to the offering by us of $65 million of

The notes will mature on June 15, 2008. Interest is fixed at an annual rate of
8% and is payable on June 15 and December 15 of each year, beginning on
December 15, 2001. We may redeem some or all of the notes at any time at the
principal amount thereof, plus accrued interest, plus the applicable make-whole

all or substantially all of our assets or experience specific kinds of changes
in control, we must offer to repurchase the notes.

The notes will be unsecured and will rank equally with all of our existing and
future senior debt and will rank senior to all of our existing and future
subordinated debt.

you should consider in connection with an investment in the notes.

                                  Our Company

    We are an independent oil and gas company engaged in the exploration,
development, acquisition, production and marketing of natural gas and liquids.
We were incorporated in New York in 1924, the successor to a company formed in
1916, and have been a publicly held company since 1969. At March 1, 2001, The
Anschutz Corporation, a private Denver-based corporation, owned approximately
31% of our outstanding common stock. We operate from production offices located
in Lafayette and Metairie, Louisiana; Denver, Colorado; Anchorage, Alaska; and
Calgary, Alberta and operate our international business (other than Canada) from
an office located in Houston, Texas. Our principal executive offices are located
in Denver, Colorado. On June 30, 2001 we employed 491 employees, of whom 340
were salaried and 151 were hourly. See "Business" for a more detailed
description of our Company.

                                  The Offering

    THE NOTES THAT WE ARE OFFERING HEREBY WILL BE IDENTICAL TO OUR OUTSTANDING
8% SENIOR NOTES DUE 2008. THE NOTES WILL EVIDENCE THE SAME DEBT AS THE
OUTSTANDING NOTES, AND THE SAME INDENTURE WILL GOVERN THE NOTES AND THE
OUTSTANDING NOTES. SEE "DESCRIPTION OF THE NOTES" FOR A DISCUSSION OF THE
INDENTURE. THE NOTES OFFERED HEREBY WILL TRADE WITH THE OUTSTANDING NOTES AS A
SINGLE CLASS OF NOTES.

    THE FOLLOWING SUMMARY CONTAINS BASIC INFORMATION ABOUT THE NOTES AND IS NOT
INTENDED TO BE COMPLETE. IT DOES NOT CONTAIN ALL INFORMATION THAT IS IMPORTANT
TO YOU. FOR A MORE COMPLETE UNDERSTANDING OF THE NOTES, PLEASE REFER TO THE
SECTION OF THIS DOCUMENT ENTITLED "DESCRIPTION OF THE NOTES."


                                      
Issuer.................................  Forest Oil Corporation.

Securities.............................  $65 million aggregate principal amount of 8% Senior Notes
                                         due 2008.

Maturity...............................  June 15, 2008.

Interest...............................  Interest on the notes will be payable semi-annually on
                                         June 15 and December 15 of each year, commencing on
                                         December 15, 2001. The notes will accrue interest from
                                         June 21, 2001.

Sinking Fund...........................  None.


                                      S-3



                                      
Optional Redemption....................  The notes will be redeemable at our option, in whole or in
                                         part, at any time at the principal amount thereof, plus
                                         accrued interest, plus the applicable make-whole premium.

Ranking................................  The notes will be general unsecured senior obligations of
                                         Forest, which will be equal in right of payment with all
                                         of our existing and future senior debt, and senior in
                                         right of payment to all of our existing and future
                                         subordinated debt. The notes will effectively rank behind
                                         all of our secured obligations to the extent of the value
                                         of the assets securing those obligations. The indenture
                                         governing the notes permits us to incur additional debt.

Specified Covenants....................  We will issue the notes under our existing indenture with
                                         State Street Bank and Trust Company, as trustee. The
                                         indenture will, among other things, limit our ability and
                                         the ability of our subsidiaries to:

                                             - incur additional debt;

                                             - pay dividends on stock, redeem stock or redeem
                                               subordinated debt;

                                             - make investments;

                                             - create liens on our assets;

                                             - sell assets;

                                             - sell capital stock of subsidiaries;

                                             - guarantee other indebtedness;

                                             - enter into agreements that restrict dividends from
                                               subsidiaries;

                                             - merge or consolidate; and

                                             - enter into transactions with affiliates.

                                         The indenture will provide that most of these covenants
                                         will terminate if:

                                             - at least one rating agency assigns the notes an
                                             investment grade rating; and

                                             - our bank credit facilities are no longer secured.

Mandatory Offers to Purchase...........  Upon the occurrence of a change of control, holders of the
                                         notes will have the right to require us to repurchase all
                                         or a portion of the notes at a price equal to 101% of the
                                         principal amount, together with any accrued and unpaid
                                         interest, if any, to the date of purchase. In connection
                                         with certain asset dispositions, we will be required to
                                         use the proceeds of the asset dispositions to make an
                                         offer to purchase the notes at 100% of the principal
                                         amount, together with accrued and unpaid interest, if any,
                                         to the date of purchase.

Use of Proceeds........................  We intend to apply all of the net proceeds from this
                                         offering initially to repay indebtedness under our U.S.
                                         credit facility. We expect to make additional borrowings
                                         under our U.S. credit facility to repurchase a portion of
                                         our subordinated indebtedness, including 8 3/4% senior
                                         subordinated notes of our subsidiary, Canadian Forest Oil
                                         Ltd.

No Listing.............................  We do not intend to apply for a listing of the notes on
                                         any securities exchange or any automated dealer quotation
                                         system.

                                  Risk Factors

    Investing in the notes involves substantial risks. You should carefully
consider all the information contained in this prospectus supplement and the
accompanying prospectus, including information in documents incorporated by
reference, prior to investing in the notes. In particular, we urge you to
consider carefully the factors set forth under "Risk Factors" beginning on
page S-8 of this prospectus supplement, including those incorporated by
reference to Forest's Annual Report on Form 10-K for the year ended
December 31, 2000.

                           Forward-Looking Statements

    The information in this prospectus supplement and the accompanying
prospectus, including information in documents incorporated by reference,
includes "forward-looking statements" within the meaning of Section 27A of the
Securities Act and Section 21E of the Exchange Act. All statements, other than
statements of historical or present facts, that address activities, events,
outcomes and other matters that Forest plans, expects, intends, assumes,
believes, budgets, predicts, forecasts, projects, estimates or anticipates (and
other similar expressions) will, should or may occur in the future are
forward-looking statements. These forward-looking statements are based on
management's current belief, based on currently available information, as to the
outcome and timing of future events. When considering forward-looking
statements, you should keep in mind the risk factors and other cautionary
statements in this prospectus supplement and the accompanying prospectus,
including those incorporated by reference to our Annual Report on Form 10-K for
the year ended December 31, 2000 as filed with the SEC.

    Forward-looking statements appear in a number of places and include
statements with respect to, among other things:

    - estimates of our future natural gas and liquids production, including
      estimates of any increases in oil and gas production;

    - planned capital expenditures and availability of capital resources to fund
      capital expenditures;

    - our outlook on oil and gas prices;

    - estimates of our oil and gas reserves;

    - the impact of political and regulatory developments;

    - our future financial condition or results of operations and our future
      revenues and expenses; and

    - our business strategy and other plans and objectives for future
      operations.

    We caution you that these forward-looking statements are subject to all of
the risks and uncertainties, many of which are beyond our control, incident to
the exploration for and development, production and sale of oil and gas. These
risks include, but are not limited to, commodity price volatility, inflation,
lack of availability of goods and services, environmental risks, drilling and
other operating risks, regulatory changes, the uncertainty inherent in
estimating proved oil and natural gas reserves and in projecting future rates of
production and timing of development expenditures and the other risks described
in our 2000 Form 10-K. The financial results of our foreign operations are also
subject to currency exchange rate risks.

    Reserve engineering is a subjective process of estimating underground
accumulations of oil and natural gas that cannot be measured in an exact way.
The accuracy of any reserve estimate depends on

                                      S-6

the quality of available data and the interpretation of that data by geological
engineers. As a result, estimates made by different engineers often vary from
one another. In addition, the results of drilling, testing and production
activities may justify revisions of estimates that were made previously. If
significant, these revisions would change the schedule of any further production
and development drilling. Accordingly, reserve estimates are generally different
from the quantities of oil and natural gas that are ultimately recovered.

    Should one or more of the risks or uncertainties described above or
elsewhere in this prospectus supplement or the accompanying prospectus occur, or
should underlying assumptions prove incorrect, our actual results and plans
could differ materially from those expressed in any forward-looking statements.

    All forward-looking statements attributable to Forest are expressly
qualified in their entirety by this cautionary statement.

                      Ratios of Earnings to Fixed Charges

    For purposes of calculating the ratio of earnings to fixed charges, earnings
consist of net earnings (loss) before minority interests in consolidated
subsidiaries, income taxes, extraordinary items, amortization of capitalized
interest, net equity in undistributed earnings of subsidiaries and fixed
charges, less capitalized interest. Fixed charges consist of interest (whether
expensed or capitalized), amortization of debt expenses and discount or premium
relating to any indebtedness and that portion of rental cost equivalent to
interest (estimated to be one-third of rental cost).

    YOU SHOULD CAREFULLY CONSIDER THE RISKS DESCRIBED BELOW AS WELL AS OTHER
INFORMATION AND DATA INCLUDED IN THIS PROSPECTUS SUPPLEMENT AND THE ACCOMPANYING
PROSPECTUS AND IN THE DOCUMENTS INCORPORATED BY REFERENCE AND THOSE TO WHICH WE
HAVE REFERRED YOU BEFORE MAKING AN INVESTMENT DECISION. IN ADDITION, YOU SHOULD
READ THE RISK FACTORS BEGINNING ON PAGE 10 OF OUR ANNUAL REPORT ON FORM 10-K FOR
THE YEAR ENDED DECEMBER 31, 2000, FILED WITH THE SECURITIES AND EXCHANGE
COMMISSION, WHICH ARE INCORPORATED HEREIN BY REFERENCE.

Risks Relating to the Notes

    FOLLOWING THIS OFFERING, WE COULD INCUR SUBSTANTIAL ADDITIONAL DEBT, WHICH
    COULD NEGATIVELY IMPACT OUR FINANCIAL CONDITION, RESULTS OF OPERATIONS AND
    BUSINESS PROSPECTS AND PREVENT US FROM FULFILLING OUR OBLIGATIONS UNDER THE
    NOTES.

    As of June 30, 2001, we had approximately $558 million in outstanding
indebtedness. Following this offering, we will be permitted to incur additional
indebtedness, provided we meet certain requirements both in the indenture
governing the notes and our other indentures and credit agreements. Our level of
indebtedness could have important consequences on our operations, including:

    - making it more difficult for us to satisfy our obligations under the notes
      or other debt and, if we fail to comply with the requirements of any of
      our debt, could result in an event of default;

    - requiring us to dedicate a substantial portion of our cash flow from
      operations to required payments on debt, thereby reducing the availability
      of cash flow for working capital, capital expenditures and other general
      business activities;

    - limiting our ability to obtain additional financing in the future for
      working capital, capital expenditures and other general corporate
      activities;

    - limiting our flexibility in planning for, or reacting to, changes in our
      business and the industry in which we operate;

    - detracting from our ability to withstand successfully a downturn in our
      business or the economy generally; and

    - placing us at a competitive disadvantage against other less leveraged
      competitors.

    The occurrence of any one of these events could have a material adverse
effect on our business, financial condition, results of operations, prospects
and ability to satisfy our obligations under the notes.

    WE MAY NOT BE ABLE TO REPURCHASE THE NOTES UPON A CHANGE OF CONTROL.

    Upon the occurrence of certain change of control events, holders of the
notes may require us to offer to repurchase all or any part of their notes. We
may not have sufficient funds at the time of the change of control to make the
required repurchases of the notes. Additionally, certain events that would
constitute a "change of control" (as defined in the indenture) would constitute
an event of default under our credit facility that would, if it should occur,
permit the lenders to accelerate the debt outstanding under our credit facility
and that, in turn, would cause an event of default under the indenture.

    The source of funds for any repurchase required as a result of any change of
control will be our available cash or cash generated from oil and gas operations
or other sources, including borrowings,

                                      S-8

sales of assets, sales of equity or funds provided by a new controlling entity.
We cannot assure you, however, that sufficient funds would be available at the
time of any change of control to make any required repurchases of the notes
tendered and to repay debt under our credit facility. Furthermore, using
available cash to fund the potential consequences of a change of control may
impair our ability to obtain additional financing in the future. Any future
credit agreements or other agreements relating to debt to which we may become a
party will most likely contain similar restrictions and provisions.

    YOU MAY BE UNABLE TO SELL THE NOTES OR TO SELL THE NOTES AT A PRICE THAT YOU
    DEEM SUFFICIENT.

    Although we have registered the notes under the Securities Act, we do not
intend to apply for listing of the notes on any securities exchange or for
quotation of the notes in any automated dealer quotation system. In addition,
the underwriter has advised us that it intends to make a market in the notes
after this offer as permitted by applicable laws and regulations; however, the
underwriter is not obligated to make a market in the notes, and it may
discontinue its market-making activities at any time without notice. Therefore,
we cannot assure you that there will be an active market for the notes.

                      RATIOS OF EARNINGS TO FIXED CHARGES

    For purposes of calculating the ratio of earnings to fixed charges, earnings
consist of net earnings (loss) before minority interests in consolidated
subsidiaries, income taxes, extraordinary items, amortization of capitalized
interest, net equity in undistributed earnings of subsidiaries and fixed
charges, less capitalized interest. Fixed charges consist of interest (whether
expensed or capitalized), amortization of debt expenses and discount or premium
relating to any indebtedness and that portion of rental cost equivalent to
interest (estimated to be one-third of rental cost).

*  The earnings for the year ended December 31, 1998 were inadequate to cover
    fixed charges. The coverage deficiency was $224,316,000.

                                USE OF PROCEEDS

    We estimate that the proceeds from this offering will be approximately
$63.6 million, after deducting fees and estimated expenses and excluding accrued
interest. We intend to apply all of the net proceeds from this offering
initially to repay indebtedness under our U.S. credit facility. Our U.S. bank
credit facility matures on October 10, 2005; as of October 15, 2001, the
weighted average interest rate on that facility was 3.73% per year. We expect to
make additional borrowings under our U.S. credit facility to repurchase a
portion of our subordinated indebtedness, including 8 3/4% senior subordinated
notes of our subsidiary, Canadian Forest Oil Ltd.

    the use of the net proceeds to reduce outstanding indebtedness under our
    U.S. credit facility. We expect to make additional borrowings under our U.S.

                                    BUSINESS

    We are an independent oil and gas company engaged in the exploration,
development, acquisition, production and marketing of natural gas and liquids.
We were incorporated in New York in 1924, the successor to a company formed in
1916, and have been a publicly held company since 1969. At March 1, 2001, The
Anschutz Corporation, a private Denver-based corporation, owned approximately
31% of our outstanding common stock. We operate from production offices located
in Lafayette and Metairie, Louisiana; Denver, Colorado; Anchorage, Alaska; and
Calgary, Alberta and operate our international business (other than Canada) from
an office located in Houston, Texas. Our principal executive offices are located
in Denver, Colorado. On June 30, 2001 we employed 491 employees, of whom 340
were salaried and 151 were hourly.

    Additional information concerning Forest is included in the reports and
other documents incorporated by reference in this prospectus supplement and the
accompanying prospectus. See "Where You Can Find More Information."

                                      S-10

                            DESCRIPTION OF THE NOTES

    We will issue the notes under our existing indenture (the "Indenture")
between us and State Street Bank and Trust Company, as trustee (the "Trustee").
This is the same Indenture pursuant to which we issued the outstanding 8% Senior
Notes due 2008. The terms of the notes include those stated in the Indenture and
those made part of the Indenture by reference to the Trust Indenture Act of 1939
(the "1939 Act"). The notes offered hereby have the same terms as the
outstanding notes and will trade with the outstanding notes as a single class of
notes. The following description is a summary of the material provisions of the
Indenture. It does not restate the Indenture in its entirety. We urge you to
read the Indenture because it, and not this description, defines your rights as
holders of these notes. The Indenture will be filed with the SEC as an exhibit
to the registration statement of which this prospectus supplement is a part. The
following description of the notes supplements, and, to the extent inconsistent
therewith, supercedes, the description of the general terms and provisions of
Debt Securities contained in the section "Description of Debt Securities" in the
accompanying prospectus.

    You will find the definitions of capitalized terms used in this description
under the heading "Certain Definitions." For purposes of this description,
references to "the Company," "we" and "us" refer only to Forest Oil Corporation
and not to its subsidiaries. References in this section to the "notes" or the
"Notes" refer to both the notes offered hereby and the outstanding 8% Senior
Notes due 2008.

    Holders of the notes offered hereby will vote together with holders of the
outstanding 8% Senior Notes due 2008 for all relevant purposes under the
Indenture. In that regard, the Indenture requires that certain actions by the
holders thereunder must be taken, and certain rights must be exercised, by
specified minimum percentages of the aggregate principal amount of the
outstanding securities issued under the Indenture. In determining whether
holders of the requisite percentage in principal amount have given any notice,
consent or waiver or taken any other action permitted under the Indenture, any
outstanding notes will be aggregated with the notes offered hereby, and the
holders of such outstanding notes and the notes will vote together as a single
class for all such purposes. Accordingly, all references herein to specified
percentages in aggregate principal amount of the notes outstanding shall be
deemed to mean, at any time after this offer is consummated, such percentages in
aggregate principal amount of the outstanding notes and the notes offered hereby
that are outstanding at that time.

Principal, Maturity and Interest

    The Notes:

    - will be general unsecured senior obligations of the Company;

    - issued in this offering will be in an aggregate principal amount of
      $65.0 million;

    - may be issued in an unlimited principal amount, subject to compliance with
      the provisions of the indenture described below under "Limitation on
      Indebtedness";

    - will mature on June 15, 2008;

    - will be issued in denominations of $1,000 and integral multiples of
      $1,000;

    - will be represented by one or more registered notes in global form, but in
      certain limited circumstances may be represented by notes in definitive
      form (see "Book Entry; Delivery and Form");

                                      S-11

    - will rank equally in right of payment with all existing and future Senior
      Indebtedness of the Company; and

    - will be senior in right of payment to any existing and future Subordinated
      Indebtedness of the Company.

    Interest on the Notes:

    - will accrue at the rate of 8% per annum;

    - will be payable semiannually in arrears on June 15 and December 15,
      commencing on December 15, 2001;

    - will be payable to the holders of record on the June 1 or December 1
      immediately preceding the related interest payment date;

    - will accrue from June 21, 2001 for the first interest payment date and
      from the most recent interest payment date for each interest payment date
      thereafter; and

    - will be computed on the basis of a 360-day year comprised of twelve
      30-day months.

    We will pay principal, premium, if any, and interest on the Notes and the
Notes will be transferable, at the office or agency designated by the Company
within the City and State of New York. In addition, in the event the Notes do
not remain in book-entry form, we may pay interest, at our option, by check
mailed to the registered holders of the Notes at their registered addresses as
set forth in the Note Register. No service charge will be made for any transfer
or exchange of Notes, but the Company or the Trustee may require payment of a
sum sufficient to cover any tax or other governmental charge that may be payable
in connection therewith.

Subsidiary Guarantees

    Under the circumstances described below under "--Certain Covenants--Future
Subsidiary Guarantors," one or more Subsidiary Guarantors will jointly and
severally guarantee the Company's payment obligations under the Notes. The
Subsidiary Guarantee of each Subsidiary Guarantor will be an unsecured senior
obligation of such Subsidiary Guarantor.

    Certain mergers, consolidations and dispositions of Property may result in
the addition of additional Subsidiary Guarantors or the release of Subsidiary
Guarantors. See "--Merger, Consolidation and Sale of Substantially All Assets."
Any Subsidiary Guarantor that is designated an Unrestricted Subsidiary in
accordance with the terms of the Indenture shall be released from and relieved
of its obligations under its Subsidiary Guarantee upon execution and delivery of
a supplementary indenture satisfactory to the Trustee.

    Each of the Company and any Subsidiary Guarantor will agree to contribute to
any Subsidiary Guarantor which makes payments pursuant to its Subsidiary
Guarantee, as applicable, an amount equal to the Company's or such Subsidiary
Guarantor's proportionate share of such payment, based on the net worth of the
Company or such Subsidiary Guarantor relative to the aggregate net worth of the
Company and the Subsidiary Guarantors.

                                      S-12

Optional Redemption

    The Notes will be redeemable, at the Company's option, at any time in whole,
or from time to time in part, at a price equal to the greater of:

    - 100% of the principal amount of the Notes to be redeemed; or

    - the sum of the present values of the remaining scheduled payments of
      principal and interest (at the rate in effect on the date of calculation
      of the redemption price) on the Notes (exclusive of interest accrued to
      the date of redemption) discounted to the date of redemption on a
      semi-annual basis (assuming a 360-day year consisting of twelve
      30-day months) at the applicable Treasury Yield plus 50 basis points;

plus, in either case, accrued interest to the date of redemption.

    Notes called for redemption become due on the date fixed for redemption.
Notices of redemption will be mailed at least 30 but not more than 60 days
before the redemption date to each holder of record of the Notes to be redeemed
at its registered address. The notice of redemption for the Notes will state,
among other things, the amount of Notes to be redeemed, the redemption date, the
redemption price and the place(s) that payment will be made upon presentation
and surrender of Notes to be redeemed. Unless the Company defaults in payment of
the redemption price, interest will cease to accrue on any Notes that have been
called for redemption at the redemption date. If less than all the Notes are
redeemed at any time, the Trustee will select the Notes to be redeemed on a pro
rata basis or by any other method the Trustee deems fair and appropriate.

    For purposes of determining the optional redemption price, the following
definitions are applicable:

    "TREASURY YIELD" means, with respect to any redemption date applicable to
the Notes, the rate per annum equal to the semi-annual equivalent yield to
maturity (computed as of the third business day immediately preceding the
redemption date) of the Comparable Treasury Issue, assuming a price for the
Comparable Treasury Issue (expressed as a percentage of its principal amount)
equal to the applicable Comparable Treasury Price for the redemption date.

    "COMPARABLE TREASURY ISSUE" means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to
the remaining term of the Notes that would be utilized, at the time of selection
and in accordance with customary financial practice, in pricing new issues of
corporate debt securities of comparable maturity to the remaining terms of the
Notes.

    "INDEPENDENT INVESTMENT BANKER" means J.P. Morgan Securities Inc. (and its
successors), or, if such firm is unwilling or unable to select the applicable
Comparable Treasury Issue, an independent investment banking institution of
national standing appointed by the Trustee and reasonably acceptable to us.

    "COMPARABLE TREASURY PRICE" means, with respect to any redemption date,
(a) the bid price for the Comparable Treasury Issue (expressed as a percentage
of its principal amount) at 4:00 p.m. on the third business day preceding the
redemption date, as set forth on "Telerate Page 500" (or such other page as may
replace Telerate Page 500), or (b) if such page (or any successor page) is not
displayed or does not contain such bid prices at such time (i) the average of
the Reference Treasury Dealer Quotations obtained by the Trustee for the
redemption date, after excluding the highest and lowest of all Reference
Treasury Dealer Quotations obtained, or (ii) if the Trustee obtains fewer than
four such Reference Treasury Dealer Quotations, the average of all Reference
Treasury Dealer Quotations obtained by the Trustee.

                                      S-13

    "REFERENCE TREASURY DEALER" means (i) J.P. Morgan Securities Inc. and its
successors, unless it ceases to be a primary U.S. government securities dealer
in New York City (a "Primary Treasury Dealer"), in which case we will substitute
therefor another Primary Treasury Dealer, and (ii) any other Primary Treasury
Dealer selected by us.

    "REFERENCE TREASURY DEALER QUOTATIONS" means, with respect to each Reference
Treasury Dealer and any redemption date for the Notes, an average, as determined
by the Trustee, of the bid and asked prices for the Comparable Treasury Issue
for the Notes (expressed in each case as a percentage of its principal amount)
quoted in writing to the Trustee by the Reference Treasury Dealer at 5:00 p.m.,
New York City time, on the third business day preceding such redemption date.

Sinking Fund

    There will be no mandatory sinking fund payments for the Notes.

Repurchase at the Option of Holders upon a Change of Control

    If a Change of Control occurs, each Holder of Notes will have the right to
require the Company to repurchase all or any part (equal to $1,000 in principal
amount or an integral multiple thereof) of that Holder's Notes pursuant to a
Change of Control Offer. In the Change of Control Offer, the Company will offer
a Change of Control Payment equal to 101% of the principal amount of the Notes
repurchased. The Company will also pay Holders of Notes being redeemed accrued
and unpaid interest, if any, to the date of purchase (subject to the right of
Holders of record on the relevant record date to receive interest due on the
relevant interest payment date).

    Within 30 days following any Change of Control, the Company will mail a
notice to each Holder stating, among other things:

    - that a Change of Control has occurred and a Change of Control Offer is
      being made pursuant to the Indenture and that all Notes (or portions
      thereof) properly tendered will be accepted for payment;

    - the purchase price and the purchase date, which shall be, subject to any
      contrary requirements of applicable law, no fewer than 30 days nor more
      than 60 days from the date the Company mails such notice (the "Change of
      Control Payment Date");

    - that any Note (or portion thereof) accepted for payment (and duly paid on
      the Change of Control Payment Date) pursuant to the Change of Control
      Offer shall cease to accrue interest on the Change of Control Payment
      Date;

    - that any Notes (or portions thereof) not properly tendered will continue
      to accrue interest;

    - a description of the transaction or transactions constituting the Change
      of Control;

    - the procedures that Holders of Notes must follow in order to tender their
      Notes (or portions thereof) for payment and the procedures that Holders of
      Notes must follow in order to withdraw an election to tender Notes (or
      portions thereof) for payment; and

    - all other instructions and materials necessary to enable Holders to tender
      Notes pursuant to the Change of Control Offer.

                                      S-14

Prior to the mailing of the notice to Holders of Notes described above, but in
any event within 30 days following any Change of Control, the Company covenants
to:

    (1) repay or cause to be repaid in full all Indebtedness of the Company and
any Subsidiary Guarantor that would prohibit the repurchase of the Notes
pursuant to such Change of Control Offer; or

    (2) obtain any requisite consents under instruments governing any such
Indebtedness of the Company and any Subsidiary Guarantor to permit the
repurchase of the Notes.

The Company shall first comply with the covenant in the preceding sentence
before it shall repurchase Notes pursuant to this "Repurchase at the Option of
Holders Upon a Change of Control" covenant.

    If the Company is unable to repay or cause to be repaid all Indebtedness
that would prohibit the repurchase of the Notes or is unable to obtain the
consents of the holders of Indebtedness, if any, outstanding at the time of a
Change of Control whose consent would be so required to permit the repurchase of
the Notes validly tendered, or if the Company for any other reason fails to
commence the Change of Control Offer when required to do so by the terms of this
covenant, then the Company will have breached such covenant. This failure to
commence the Change of Control Offer will constitute an Event of Default under
the Indenture if it continues for a period of 30 consecutive days after written
notice is given to the Company by the Trustee or the Holders of at least 25% in
aggregate principal amounts of the Notes outstanding. In addition, the failure
by the Company to repurchase Notes at the conclusion of the Change of Control
Offer will constitute an Event of Default under the Indenture without any
waiting period or notice requirements. Such Event of Default would, in turn,
constitute a default under the existing Bank Credit Facilities and may
constitute a default under the terms of any other Indebtedness of the Company or
any Subsidiary Guarantor then outstanding.

    The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations to the extent such
laws and regulations are applicable in connection with the repurchase of Notes
as a result of a Change of Control. To the extent that the provisions of any
securities laws or regulations conflict with the provisions of the covenant
described hereunder, the Company will comply with the applicable securities laws
and regulations and will not be deemed to have breached any covenant.

    The Company's obligation to repurchase the Notes upon a Change of Control
will be guaranteed on an unsecured senior basis, to the extent any Restricted
Subsidiary becomes a Subsidiary Guarantor, by such Subsidiary Guarantor pursuant
to its Subsidiary Guarantee.

    If a Change of Control were to occur, there can be no assurance that the
Company and the Subsidiary Guarantors, if any, would have sufficient financial
resources, or would be able to arrange financing and pay the purchase price for
all Notes tendered by the Holders thereof. The provisions under the Indenture
related to the Company's obligations to make an offer to repurchase the Notes as
a result of a Change of Control may be waived or modified (at any time prior to
the occurrence of such Change of Control) with the written consent of the
Holders of a majority in principal amount of the Notes.

    The Company will not be required to make a Change of Control Offer upon a
Change of Control if a third party (including any Subsidiary of the Company)
makes the Change of Control Offer in the manner, at the times and otherwise in
compliance with the requirements set forth in the Indenture applicable to a
Change of Control Offer made by the Company and purchases all Notes validly
tendered and not withdrawn under such Change of Control Offer.

                                      S-15

    A "Change of Control" shall be deemed to occur if:

    (1) any "person" or "group" (within the meaning of Sections 13(d)(3) and
14(d)(2) of the Exchange Act or any successor provision to either of the
foregoing, including any group acting for the purpose of acquiring, holding or
disposing of securities within the meaning of Rule 13d-5(b)(1) under the
Exchange Act), becomes the "beneficial owner" (as defined in Rules 13d-3 and
13d-5 under the Exchange Act, except that a Person will be deemed to have
"beneficial ownership" of all shares that any such Person has the right to
acquire, whether such right is exercisable immediately or only after the passage
of time) of more than 50% of the total voting power of all classes of the Voting
Stock of the Company outstanding or subject to currently exercisable warrants or
options to acquire such Voting Stock;

    (2) the sale, lease, conveyance or transfer of all or substantially all the
assets of the Company and the Restricted Subsidiaries taken as a whole (other
than to any Wholly Owned Subsidiary) shall have occurred;

    (3) the shareholders of the Company shall have approved any plan of
liquidation or dissolution of the Company;

    (4) the Company consolidates with or merges into another Person or any
Person consolidates with or merges into the Company in any such event pursuant
to a transaction in which the outstanding Voting Stock of the Company is
reclassified into or exchanged for cash, securities or other property, other
than any such transaction where the outstanding Voting Stock of the Company is
reclassified into or exchanged for Voting Stock of the surviving corporation
that is Capital Stock and the holders of the Voting Stock of the Company
immediately prior to such transaction own, directly or indirectly, not less than
a majority of the Voting Stock of the surviving corporation immediately after
such transaction in substantially the same proportion as before the transaction
(for the purposes of this clause (4), the holders of the Voting Stock
immediately prior to such transaction shall be deemed to beneficially own any
Voting Stock of a specified corporation held by a parent corporation, if the
holders of the Voting Stock immediately prior to such transaction are the
beneficial owners (as defined in clause 1 above), directly or indirectly, of
more than 50% of the voting power of the Voting Stock of such parent
corporation); or

    (5) during any period of two consecutive years, individuals who at the
beginning of such period constituted the Company's Board of Directors (together
with any new directors whose election or appointment by such Board or whose
nomination for election by the shareholders of the Company was approved by a
vote of a majority of the directors then still in office who were either
directors at the beginning of such period or whose election or nomination for
election was previously so approved) cease for any reason to constitute a
majority of the Company's Board of Directors then in office.

    The definition of Change of Control includes a phrase relating to the sale,
lease, conveyance or transfer of "all or substantially all" the Company's and
its Restricted Subsidiaries' assets taken as a whole. The Indenture is governed
by New York law, and there is no established quantitative definition under New
York law of "substantially all" the assets of a corporation. Accordingly, the
ability of a Holder of Notes to require the Company to repurchase such Notes as
a result of a sale, lease, conveyance or transfer of less than all the assets of
the Company and its Restricted Subsidiaries taken as a whole may be uncertain.

    Except as described above with respect to a Change of Control, the Indenture
does not contain any other provision that permits the Holders of the Notes to
require that the Company repurchase or redeem the Notes in the event of a
takeover, recapitalization or similar restructuring.

                                      S-16

      under Bank Credit Facilities and not subsequently reinvested in Additional
      Assets or used to permanently reduce other Indebtedness to the extent
      permitted pursuant to the provisions of the Indenture described under
      "--Limitation on Asset Sales;" and

    - an amount equal to the sum of (a) $150.0 million and (b) 25% of Adjusted

obligations issued by or for the account of the Company or any Restricted
Subsidiary in the ordinary course of business,

immediately preceding paragraph), PROVIDED that the aggregate principal amount
of all Indebtedness Incurred pursuant to this clause (9), together with all
Indebtedness Incurred pursuant to clause (10) of this paragraph in respect of
Indebtedness previously Incurred pursuant to this clause (9), at any one time
outstanding does not exceed $75.0 million;

    (10) Indebtedness Incurred in exchange for, or the proceeds of which are

(8) and (9) of this paragraph (including Indebtedness previously Incurred
pursuant to this clause (10)) and (b) Indebtedness Incurred pursuant to
clause (1) of the immediately preceding paragraph, PROVIDED that, in the case of
each of the foregoing clauses (a) and (b), such Indebtedness is Permitted
Refinancing Indebtedness; and

    (11) Indebtedness consisting of obligations in respect of purchase price
adjustments, indemnities or Guarantees of the same or similar matters in
connection with the acquisition or disposition of Property.

    For purposes of determining compliance with the foregoing covenant:

    - in the event that an item of Indebtedness (including Indebtedness Incurred
      by the Company to banks or other lenders) could be Incurred pursuant to
      more than one of the above provisions, the Company, in its sole
      discretion, will classify such item of Indebtedness and only be required
      to include the amount and type of such Indebtedness in (and to have
      Incurred such Indebtedness pursuant to) one of the above clauses; and

    - an item of Indebtedness (including Indebtedness Incurred by the Company to
      banks or other lenders) may for this purpose be divided into more than one
      of the types of Indebtedness described above.

    LIMITATION ON LIENS.  The Company will not, and will not permit any
Restricted Subsidiary to, directly or indirectly, enter into, create, Incur,
assume or suffer to exist any Lien on or with respect to any Property of the
Company or such Restricted Subsidiary, whether owned on the Issue Date or
acquired thereafter, or any interest therein or any income or profits therefrom,
unless the Notes or any Subsidiary Guarantee of such Restricted Subsidiary, as
applicable, are secured equally and ratably with (or prior to) any and all other
obligations secured by such Lien, except that the Company and its Restricted
Subsidiaries may enter into, create, incur, assume or suffer to exist Permitted
Liens.

    LIMITATION ON RESTRICTED PAYMENTS.  The Company will not, and will not
permit any Restricted Subsidiary to, directly or indirectly, make any Restricted
Payment if, at the time of and after giving effect to the proposed Restricted
Payment:

    (1) any Default or Event of Default would have occurred and be continuing;

                                      S-18

    (2) the Company could not Incur at least $1.00 of additional Indebtedness
pursuant to clause (1) of the first paragraph under "--Limitation on
Indebtedness;" or

    (3) the aggregate amount expended or declared for all Restricted Payments
from September 30, 2000 would exceed the sum (without duplication) of the
following:

        (a) 50% of the aggregate Consolidated Net Income of the Company accrued
    on a cumulative basis commencing on the last day of the fiscal quarter
    immediately preceding September 30, 2000 and ending on the last day of the
    fiscal quarter ending on or immediately preceding the date of such proposed
    Restricted Payment (or, if such aggregate Consolidated Net Income shall be a
    loss, minus 100% of such loss), plus

        (b) the aggregate net cash proceeds, or the Fair Market Value of
    Property other than cash, received by the Company on or after September 30,
    2000 from the issuance or sale (other than to a Subsidiary of the Company)
    of Capital Stock of the Company or any options, warrants, or rights to
    purchase Capital Stock of the Company, plus

        (c)  the aggregate net cash proceeds, or the Fair Market Value of
    Property other than cash, received by the Company as capital contributions
    to the Company (other than from a Subsidiary of the Company) on or after
    September 30, 2000, plus

        (d) the aggregate net cash proceeds received by the Company from the
    issuance or sale (other than to any Subsidiary of the Company) on or after

    cash received by the Company at the time of such conversion or exchange or
    received by the Company from any such conversion or exchange of convertible
    Indebtedness issued or sold (other than to any Subsidiary of the Company)

        (e) to the extent not otherwise included in the Company's Consolidated
    Net Income, an amount equal to the net reduction in Investments made by the
    Company and its Restricted Subsidiaries subsequent to September 30, 2000 in
    any Person resulting from (i) payments of interest on debt, dividends,

    not to exceed the book value of such Investments previously made in such
    Person that were treated as Restricted Payments, or (ii) the designation of
    any Unrestricted Subsidiary as a Restricted Subsidiary, and in an amount not

As of June 30, 2001, the Company had total availability to make Restricted
Payments under clause (3) above of approximately $135.4 million.

    The limitations set forth in the preceding paragraph will not prevent the
following Restricted Payments so long as, at the time thereof, no Default or
Event of Default shall have occurred and be continuing (except in the case of
clause (1) below under which the payment of a dividend is permitted):

    (1) the payment of any dividend on Capital Stock or Redeemable Stock of the
Company or any Restricted Subsidiary within 60 days after the declaration
thereof, if at such declaration date such dividend could have been paid in
compliance with the preceding paragraph;

                                      S-19

    (2) the repurchase, redemption or other acquisition or retirement for value
of any Capital Stock of the Company or any of its Subsidiaries held by any
current or former officers, directors, or employees of the Company or any of its
Subsidiaries pursuant to the terms of agreements (including employment
agreements) or plans approved by the Company's Board of Directors, including any
such repurchase, redemption, acquisition or retirement of shares of such Capital
Stock that is deemed to occur upon the exercise of stock options or similar
rights if such shares represent all or a portion of the exercise price or are
surrendered in connection with satisfying United States or Canadian Federal
income tax obligations; PROVIDED, HOWEVER, that the aggregate amount of such
repurchases, redemptions, acquisitions and retirements shall not exceed the sum

Permitted Refinancing Indebtedness and (a) has an Average Life that is longer
than the Average Life of the Notes and (b) has a Stated Maturity for its final

stock of the Company in connection with a restricted stock or employee stock
purchase plan, or to exercise stock options received pursuant to an employee or
director stock option plan or other incentive plan, in a principal amount not to
exceed the exercise price of such

                                      S-20

stock options or (b) to refinance loans, together with accrued interest thereon,
made pursuant to item (a) of this clause (7).

    The actions described in clauses (1) and (2) of this paragraph shall be
included in the calculation of the amount of Restricted Payments. The actions
described in clauses (3), (4), (5), (6) and (7) of this paragraph shall be
excluded in the calculation of the amount of Restricted Payments, PROVIDED that
the net cash proceeds from any issuance or sale of Capital Stock of the Company
pursuant to such clauses (3), (4) or (7) shall be excluded from any calculations
pursuant to clauses (b) or (c) under the immediately preceding paragraph.

    LIMITATION ON ISSUANCE AND SALE OF CAPITAL STOCK OF RESTRICTED
SUBSIDIARIES.  The Company will not (a) permit any Restricted Subsidiary to
issue any Capital Stock or Redeemable Stock other than to the Company or one of
its Wholly Owned Subsidiaries or (b) permit any Person other than the Company or
a Wholly Owned Subsidiary to own any Capital Stock or Redeemable Stock of any
other Restricted Subsidiary (other than directors' qualifying shares), except,
in each case, for:

    (1) the sale of the Capital Stock or Redeemable Stock of a Restricted
Subsidiary owned by the Company or any other Restricted Subsidiary effected in
accordance with the provisions of the Indenture described under "--Limitation on
Asset Sales;"

    (2) the issuance of Capital Stock or Redeemable Stock by a Restricted
Subsidiary to a Person other than the Company or a Restricted Subsidiary; and

    (3) the Capital Stock or Redeemable Stock of a Restricted Subsidiary owned
by a Person at the time such Restricted Subsidiary became a Restricted
Subsidiary or acquired by such Person in connection with the formation of the
Restricted Subsidiary, or transfers thereof;

PROVIDED, that any sale or issuance of Capital Stock of a Restricted Subsidiary
shall be deemed to be an Asset Sale to the extent the percentage of the total
outstanding Voting Stock of such Restricted Subsidiary owned directly and
indirectly by the Company is reduced as a result of such sale or issuance;
PROVIDED, FURTHER that if a Person whose Capital Stock was issued or sold in a
transaction described in this paragraph is, as a result of such transaction, no
longer a Restricted Subsidiary, then the Fair Market Value of Capital Stock of
such Person retained by the Company and the other Restricted Subsidiaries shall
be treated as an Investment for purposes of the provisions of the Indenture
described under "--Limitation on Restricted Payments." In the event of the
consummation of a sale of all the Capital Stock of a Restricted Subsidiary
pursuant to the foregoing clause (1) and the execution and delivery of a
supplemental indenture in form satisfactory to the Trustee, any such Restricted
Subsidiary that is also a Subsidiary Guarantor shall be released from all its
obligations under its Subsidiary Guaranty.

    LIMITATION ON ASSET SALES.  The Company will not, and will not permit any
Restricted Subsidiary to, consummate any Asset Sale unless:

     (1) the Company or such Restricted Subsidiary, as the case may be, receives
consideration at the time of such Asset Sale at least equal to the Fair Market
Value of the Property subject to such Asset Sale; and

     (2) all of the consideration paid to the Company or such Restricted
Subsidiary in connection with such Asset Sale is in the form of cash, cash
equivalents, Liquid Securities, Exchanged Properties or the assumption by the
purchaser of liabilities of the Company (other than liabilities of the Company
that are by their terms subordinated to the Notes) or liabilities of any
Restricted Subsidiary that made such Asset Sale (other than liabilities of any
Subsidiary Guarantor that are by their terms subordinated to such

                                      S-21

Subsidiary Guarantor's Subsidiary Guarantee), in each case as a result of which
the Company and its remaining Restricted Subsidiaries are no longer liable for
such liabilities ("Permitted Consideration"); PROVIDED, HOWEVER, that the
Company and its Restricted Subsidiaries shall be permitted to receive Property
other than Permitted Consideration, so long as the aggregate Fair Market Value
of all such Property other than Permitted Consideration received from Asset
Sales and held by the Company and the Restricted Subsidiaries at any one time
shall not exceed 10.0% of Adjusted Consolidated Net Tangible Assets.

    The Net Available Cash from Asset Sales by the Company or a Restricted
Subsidiary may be applied by the Company, such Restricted Subsidiary or another
Restricted Subsidiary, to the extent the Company elects (or is required by the
terms of any Pari Passu Indebtedness of the Company or a Restricted Subsidiary),
to:

     (1) prepay, repay or purchase Pari Passu Indebtedness of the Company or a
Subsidiary Guarantor or any Indebtedness of a Restricted Subsidiary that is not
a Subsidiary Guarantor (in each case excluding Indebtedness owed to the Company
or an Affiliate of the Company);

     (2) to reinvest in Additional Assets (including by means of an Investment
in Additional Assets by a Restricted Subsidiary with Net Available Cash received
by the Company or another Restricted Subsidiary); or

     (3) purchase Notes or purchase both Notes and one or more series or issues
of other Pari Passu Indebtedness on a pro rata basis (excluding Notes and Pari
Passu Indebtedness owned by the Company or an Affiliate of the Company).

    Any Net Available Cash from an Asset Sale not applied in accordance with the
preceding paragraph within 365 days from the date of such Asset Sale will
constitute "Excess Proceeds." When the aggregate amount of Excess Proceeds
exceeds $50.0 million, an offer to purchase Notes having an aggregate principal
amount equal to the aggregate amount of Excess Proceeds (the "Prepayment Offer")
must be made by the Company at a purchase price equal to 100% of the principal
amount of such Notes plus accrued and unpaid interest, if any, to the Purchase
Date (as defined) in accordance with the procedures (including prorating in the
event of oversubscription) set forth in the Indenture, but, if the terms of any
Pari Passu Indebtedness require that a Pari Passu Indebtedness Offer be made
contemporaneously with the Prepayment Offer, then the Excess Proceeds shall be
prorated between the Prepayment Offer and such Pari Passu Offer in accordance
with the aggregate outstanding principal amounts of the Notes and such Pari
Passu Indebtedness, and the aggregate principal amount of Notes for which the
Prepayment Offer is made shall be reduced accordingly. If the aggregate
principal amount of Notes tendered by Holders thereof exceeds the amount of
available Excess Proceeds, then such Excess Proceeds will be allocated pro rata
according to the principal amount of the Notes tendered and the Trustee will
select the Notes to be purchased in accordance with the Indenture. To the extent
that any portion of the amount of Excess Proceeds remains after compliance with
the second sentence of this paragraph and PROVIDED that all Holders of Notes
have been given the opportunity to tender their Notes for purchase as described
in the following paragraph in accordance with the Indenture, the Company and its
Restricted Subsidiaries may use such remaining amount for purposes permitted by
the Indenture and the amount of Excess Proceeds will be reset to zero.

                                      S-22

    Within 30 days after the 365th day following the date of an Asset Sale, the
Company shall, if it is obligated to make an offer to purchase the Notes
pursuant to the preceding paragraph, send a written Prepayment Offer notice, by
first-class mail, to the Holders of the Notes (the "Prepayment Offer Notice"),
accompanied by such information regarding the Company and its Subsidiaries as
the Company believes will enable such Holders of the Notes to make an informed
decision with respect to the Prepayment Offer. The Prepayment Offer Notice will
state, among other things:

    - that the Company is offering to purchase Notes pursuant to the provisions
      of the Indenture;

    - that any Note (or any portion thereof) accepted for payment (and duly paid
      on the Purchase Date) pursuant to the Prepayment Offer shall cease to
      accrue interest on the Purchase Date;

    - that any Notes (or portions thereof) not properly tendered will continue
      to accrue interest;

    - the purchase price and purchase date, which shall be, subject to any
      contrary requirements of applicable law, no less than 30 days nor more
      than 60 days after the date the Prepayment Offer Notice is mailed (the
      "Purchase Date");

    - the aggregate principal amount of Notes to be purchased;

    - a description of the procedure which Holders of Notes must follow in order
      to tender their Notes and the procedures that Holders of Notes must follow
      in order to withdraw an election to tender their Notes for payment; and

    - all other instructions and materials necessary to enable Holders to tender
      Notes pursuant to the Prepayment Offer.

    The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations to the extent such
laws and regulations are applicable in connection with the purchase of Notes as
described above. To the extent that the provisions of any securities laws or
regulations conflict with the provisions relating to the Prepayment Offer, the
Company will comply with the applicable securities laws and regulations and will
not be deemed to have breached any covenant.

    LIMITATION ON TRANSACTIONS WITH AFFILIATES.  The Company will not, and will
not permit any of its Restricted Subsidiaries to, directly or indirectly,
conduct any business or enter into any transaction or series of transactions
(including the sale, transfer, disposition, purchase, exchange or lease of
Property, the making of any Investment, the giving of any Guarantee or the
rendering of any service) with or for the benefit of any Affiliate of the
Company (other than the Company or a Restricted Subsidiary), unless:

     (1) such transaction or series of transactions is on terms no less
favorable to the Company or such Restricted Subsidiary than those that could be
obtained in a comparable arm's-length transaction with a Person that is not an
Affiliate of the Company or such Restricted Subsidiary; and

     (2) with respect to a transaction or series of transactions involving
aggregate payments by or to the Company or such Restricted Subsidiary having a
Fair Market Value equal to or in excess of:

        (a) $5.0 million but less than $10.0 million, an officer of the Company
    certifies that such transaction or series of transactions complies with
    clause (1) of this paragraph, as evidenced by an Officer's Certificate
    delivered to the Trustee;

        (b) $10.0 million but less than $50.0 million, the Board of Directors of
    the Company (including a majority of the disinterested members of such Board

    RESTRICTED AND UNRESTRICTED SUBSIDIARIES.  Unless defined or designated as
an Unrestricted Subsidiary, any Person that becomes a Domestic Subsidiary or a
Canadian Subsidiary of the Company or any of its Restricted Subsidiaries shall
be classified as a Restricted Subsidiary subject to the provisions of the next
paragraph. The Company may designate a Subsidiary (including a newly formed or
newly acquired Subsidiary) of the Company or any of its Restricted Subsidiaries
as an Unrestricted Subsidiary if:

     (1) such Subsidiary does not at such time own any Capital Stock or
Indebtedness of, or own or hold any Lien on any Property of, the Company or any
other Restricted Subsidiary;

     (2) such Subsidiary does not at such time have any Indebtedness or other
obligations which, if in default, would result (with the passage of time or
notice or otherwise) in a default on any Indebtedness of the Company or any
Restricted Subsidiary; and

     (3) (a)  such designation is effective immediately upon such Subsidiary
becoming a Subsidiary of
    the Company or of a Restricted Subsidiary;

        (b) the Subsidiary to be so designated has total assets of $1,000 or
    less; or

        (c)  if such Subsidiary has assets greater than $1,000, then such
    redesignation as an Unrestricted Subsidiary is deemed to constitute a
    Restricted Payment in an amount equal to the Fair Market Value of the
    Company's direct and indirect ownership interest in such Subsidiary and such
    Restricted Payment would be permitted to be made at the time of such
    designation under the provisions of the Indenture described under
    "--Limitation on Restricted Payments."

Except as provided in the second sentence of this paragraph, no Restricted
Subsidiary may be redesignated as an Unrestricted Subsidiary. The designation of
an Unrestricted Subsidiary or removal of such designation shall be made by the
Board of Directors of the Company or a committee thereof pursuant to a certified
resolution delivered to the Trustee and shall be effective as of the date
specified in the applicable certified resolution, which shall not be prior to
the date such certified resolution is delivered to the Trustee.

    The Company will not, and will not permit any of its Restricted Subsidiaries
to, take any action or enter into any transaction or series of transactions that
would result in a Person becoming a Restricted Subsidiary (whether through an
acquisition or otherwise) unless, after giving effect to such action,
transaction or series of transactions, on a pro forma basis, the Company could
Incur at least $1.00 of additional Indebtedness pursuant to clause (1) of the
first paragraph under "--Limitation on Indebtedness;" and no Default or Event of
Default would occur or be continuing.

Merger, Consolidation and Sale of Substantially All Assets

    (1) the resulting, surviving or transferee person (the "Successor Company")
shall be a Person organized or existing under the laws of:

    - the United States of America, any State thereof or the District of
      Columbia; or

    - Canada or any province thereof;

    (2) a supplemental indenture is executed and delivered to the Trustee, in
form satisfactory to the Trustee, by the Successor Company expressly assuming,
if the Successor Company is not the Company,

                                      S-26

the obligations of the Company to pay the principal of and interest on the Notes
and to perform all the covenants of the Company under the Indenture (in which
case the Successor Company shall be considered the issuer of the Notes);

    (3) each Subsidiary Guarantor shall execute and deliver to the Trustee a
supplemental indenture, in form satisfactory to the Trustee, confirming the
obligation of such Subsidiary Guarantor to pay the principal of and interest on
the Notes pursuant to such Subsidiary Guarantor's Subsidiary Guarantee;

    (4) in the case of a conveyance, transfer or lease of all or substantially
all the Property of the Company and its Restricted Subsidiaries, taken as a
whole, such Property shall have been so conveyed, transferred or leased as an
entirety or virtually as an entirety to one Person;

    (5) immediately after giving effect to such transaction (and treating, for
purposes of this clause (5) and clauses (6) and (7) below, any Indebtedness
which becomes or is anticipated to become an obligation of the Successor Company
or any Restricted Subsidiary as a result of such transaction as having been
Incurred by such Successor Company or such Restricted Subsidiary at the time of
such transaction), no Default or Event of Default shall have occurred and be
continuing;

    (6) other than with respect to the consolidation of the Company with or
merger of the Company with or into, or the conveyance, transfer or lease of all
or substantially all the Property of the Company and its Restricted
Subsidiaries, taken as a whole, to, a Wholly Owned Subsidiary, immediately after
giving effect to such transaction, the Successor Company would be able to Incur
an additional $1.00 of Indebtedness pursuant to clause (1) of the first
paragraph under "--Limitation on Indebtedness;"

    (7) other than with respect to the consolidation of the Company with or
merger of the Company with or into, or the conveyance, transfer or lease of all
or substantially all the Property of the Company and its Restricted
Subsidiaries, taken as a whole, to, a Wholly Owned Subsidiary, immediately after
giving effect to such transaction, the Successor Company shall have Consolidated
Net Worth in an amount that is not less than the Consolidated Net Worth of the
Company immediately prior to such transaction; and

    (8) the Company shall have delivered to the Trustee an Officer's
Certificate, stating that such consolidation, merger or transfer and such
supplemental indenture (if any) comply with the Indenture.

    The Successor Company shall be the successor to the Company and shall
succeed to, and be substituted for, and may exercise every right and power of
the Company under the Indenture, and, except in the case of the lease of all or
substantially all the Property of the Company and its Restricted Subsidiaries,
taken as a whole, the Company shall be released from its obligations under the
Indenture.

    Commission guidelines, attributable to reserves subject to

    Restricted Subsidiaries in respect of any Sale and Leaseback Transaction
    that is Indebtedness allocable to interest expense (determined as if such

    The Company and the Subsidiary Guarantors will, at the election of the

the Notes ("Legal Defeasance") except for obligations:

    (1) to exchange or register the transfer of Notes;

    (2) to replace stolen, lost or mutilated Notes;

    (3) to maintain paying agencies; and

    (4) to hold moneys for payment in trust.

    In addition, the Company may omit to comply with certain covenants,
including those described under "--Repurchase at the Option of Holders Upon a
Change of Control," "--Certain Covenants" and in clauses (6) and (7) under the
first paragraph of "--Merger, Consolidation and Sale of Substantially All
Assets"("Covenant Defeasance") and the occurrence of the Events of Default
described below in clauses (3) and (4) (with respect to such covenants) and
clauses (5), (6), (7) (with respect to Significant Subsidiaries) and (8)), under
"--Events of Default and Notice" will be deemed not to be or result in an Event
of Default.

    Such Legal Defeasance or Covenant Defeasance may occur only if, among other
things, the Company:

    (1) deposits in trust for the benefit of the Holders of the Notes money or
U.S. Government Obligations, or a combination thereof, which, through the
payment of principal, interest and any premium in respect thereof in accordance
with their terms, will provide money in an amount sufficient to pay the
principal of and any premium and interest on the Notes at Stated Maturity
thereof or on earlier redemption in accordance with the terms of the Indenture
and the Notes;

    (2) in the case of Legal Defeasance, delivers to the Trustee an Opinion of
United States Counsel to the effect that:

        (a) the Company has received from, or there has been published by, the
    United States Internal Revenue Service a ruling or since the date of
    Indenture there has been a change in the applicable federal income tax law,
    in either case to the effect that Holders of the Notes will not recognize
    income, gain or loss for federal income tax purposes as a result of such
    deposit, defeasance and discharge and will be subject to federal income tax
    on the same amount, in the same manner and at the same times as would have
    been the case if such deposit, defeasance and discharge were not to occur;
    and

        (b) the resulting trust will not be an "Investment Company" within the
    meaning of the Investment Company Act of 1940 or that such trust is
    qualified thereunder or exempt from regulation thereunder;

                                      S-49

    (3) in the case of Covenant Defeasance, delivers to the Trustee an Opinion
of United States Counsel to the effect that:

        (a) Holders of the Notes will not recognize income, gain or loss for
    federal income tax purposes as a result of such deposit and defeasance of
    certain obligations and will be subject to federal income tax on the same
    amount, in the same manner and at the same times as would have been the case
    if such deposit and defeasance were not to occur; and

        (b) that the resulting trust will not be an "Investment Company" within
    the meaning of the Investment Company Act of 1940 or that such trust is
    qualified thereunder or exempt from regulation thereunder.

    If the Company were to exercise this option and the Notes were declared due
and payable because of the occurrence of any Event of Default, the amount of
money and U.S. Government Obligations so deposited in trust would be sufficient
to pay amounts due on the Notes at the time of their Stated Maturity but might
not be sufficient to pay amounts due on the Notes upon any acceleration
resulting from such Event of Default. In such case, the Company would remain
liable for such payments.

    If the Company exercises either of the options described above, each
Subsidiary Guarantor will be released from all its obligations under its
Subsidiary Guarantee.

Events of Default and Notice

    The following are summaries of Events of Default under the Indenture with
respect to the Notes:

    (1) failure to pay any interest on the Notes when due, continued for

    (3) failure to comply with the provisions of the Indenture described under
"Merger, Consolidation and Sale of Substantially All Assets;"

    (4) failure to perform any other covenant of the Company or any Subsidiary
Guarantor in the Indenture, continued for 60 days after written notice to the
Company from the Trustee or the Holders of at least 25% in aggregate principal
amount of the outstanding Notes;

    (5) a default by the Company or any Restricted Subsidiary under any
Indebtedness for borrowed money (other than Non-recourse Purchase Money
Indebtedness) which results in acceleration of the maturity of such
Indebtedness, or failure to pay any such Indebtedness at maturity, in an amount
greater than $10.0 million if such Indebtedness is not discharged or such
acceleration is not rescinded or annulled within 10 days after written notice as
provided in the Indenture;

    (6) one or more final judgments or orders by a court of competent
jurisdiction are entered against the Company or any Restricted Subsidiary in an
uninsured or unindemnified aggregate amount outstanding at any time in excess of
$10.0 million and such judgment or orders are not discharged, waived, stayed,
satisfied or bonded for a period of 60 consecutive days;

    (7) certain events of bankruptcy, insolvency or reorganization with respect
to the Company or any Significant Subsidiary; or

    (8) a Subsidiary Guarantee ceases to be in full force and effect (other than
in accordance with the terms of the Indenture and such Subsidiary Guarantee) or
a Subsidiary Guarantor denies or disaffirms its obligations under its Subsidiary
Guarantee.

    If an Event of Default (other than an Event of Default described in
clause (7) above) occurs and is continuing, either the Trustee or the Holders of
at least 25% in aggregate principal amount of the outstanding Notes by notice as
provided in the Indenture may declare the principal amount of the Notes to be
due and payable immediately. If an Event of Default described in
clause (7) above occurs, the principal amount of all the Notes will
automatically, and without any action by the Trustee or any Holder, become
immediately due and payable. After any such acceleration, but before a judgment
or decree based on acceleration, the Holders of at least a majority in aggregate
principal amount of the outstanding Notes may, under certain circumstances,
rescind and annul such acceleration if all Events of Default, other than the
nonpayment of accelerated principal (or other specified amount), have been cured
or waived as provided in the Indenture.

    Subject to the provisions of the Indenture relating to the duties of the
Trustee, in case an Event of Default occurs and is continuing, the Trustee will
be under no obligation to exercise any of its rights or powers under the
Indenture at the request or direction of any of the Holders of the Notes, unless
such Holders shall have offered to the Trustee reasonable indemnity. Subject to
such provisions for the indemnification of the Trustee, the Holders of at least
a majority in aggregate principal amount of the outstanding Notes will have the
right to direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee or exercising any trust or power conferred on
the Trustee with respect to the Notes.

    No Holder of Notes will have any right to institute any proceeding with
respect to the Indenture, or for the appointment of a receiver or a trustee, or
for any other remedy thereunder, unless:

    (1) such Holder has previously given to the Trustee written notice of a
continuing Event of Default with respect to the Notes;

    (2) the Holders of at least 25% in aggregate principal amount of the
outstanding Notes have made written request, and such Holder or Holders have
offered reasonable indemnity, to the Trustee to institute such proceeding as
trustee; and

    (3) the Trustee has failed to institute such proceeding and has not received
from the Holders of at least a majority in aggregate principal amount of the
outstanding Notes a direction inconsistent with such request, within 60 days
after such notice, request and offer.

    However, such limitations do not apply to a suit instituted by a Holder of
Notes for the enforcement of payment of the principal of or any premium or
interest on such Notes on or after the applicable due date specified in such
Notes.

Modification of the Indenture; Waiver

    Modifications and amendments of the Indenture may be made by the Company,
the Subsidiary Guarantors and the Trustee without the consent of any Holders of
Notes in certain limited circumstances, including:

    (1) to cure any ambiguity, omission, defect or inconsistency;

    (2) to provide for the assumption of the obligations of the Company under
the Indenture upon the merger, consolidation or sale or other disposition of all
or substantially all the assets of the Company and the Restricted Subsidiaries
taken as a whole and certain other events specified in the provisions of the
Indenture described under "--Merger, Consolidation and Sale of Substantially All
Assets;"

                                      S-51

    (3) to provide for uncertificated Notes in addition to or in place of
certificated Notes;

    (4) to comply with any requirement of the Commission in order to effect or
maintain the qualification of the Indenture under the 1939 Act;

    (5) to make any change that does not adversely affect the rights of any
Holder of Notes in any material respect;

    (6) to add or remove Subsidiary Guarantors pursuant to the procedure set
forth in the Indenture; and

    (7) to make certain other modifications and amendments as set forth in the
Indenture.

    The Company, the Subsidiary Guarantors and the Trustee may, with the written
consent of the Holders of not less than a majority in aggregate principal amount
of the outstanding Notes, execute supplemental indentures or amendments adding
any provisions to or changing or eliminating any of the provisions of the
Indenture or modifying the rights of the Holders of the Notes, except that no
such supplemental indenture, amendment or waiver may, without the consent of all
the Holders of outstanding Notes, among other things:

    (1) reduce the principal amount of Notes whose Holders must consent to an
amendment or waiver;

    (2) reduce the rate of or change the time for payment of interest on any
Notes;

    (3) change the currency in which any amount due in respect of the Notes is
payable;

    (4) reduce the principal of or any premium on or change the Stated Maturity
of any Notes or alter the redemption or repurchase provisions with respect
thereto;

    (5) reduce the relative ranking of any Notes;

    (6) release any security that may have been granted to the Trustee in
respect of the Notes;

    (7) at any time after a Change of Control or an Asset Sale has occurred,
change the time at which the Change of Control Offer or Prepayment Offer
relating thereto must be made or at which the Notes must be repurchased pursuant
to such Change of Control Offer or Prepayment Offer;

    (8) cause the Company or any Subsidiary Guarantor to be required to make any
deduction or withholding from payments made under or with respect to the Notes;
or

    (9) make certain other significant amendments or modifications as specified
in the Indenture.

    The Holders of at least a majority in principal amount of the outstanding
Notes may waive compliance by the Company with certain restrictive provisions of
the Indenture. The Holders of at least a majority in principal amount of the
outstanding Notes may waive any past default under the Indenture, except a
default in the payment of principal, premium or interest and certain covenants
and provisions of the Indenture which cannot be amended without the consent of
the Holders of each outstanding Note.

                                      S-52

Notices

    Notices to Holders of the Notes will be given by mail to the addresses of
such Holders as they may appear in the Security Register.

Governing Law

    The Indenture and the Notes are governed by and construed in accordance with
the laws of the State of New York.

Book-Entry, Delivery and Form

    The notes will be issued in the form of one or more global securities. The
global securities will be deposited with, or on behalf of The Depository Trust
Company, or DTC, and registered in the name of Cede & Co., as nominee of DTC, or
will remain in the custody of the trustee pursuant to the FAST Balance
Certificate Agreement between DTC and the trustee. Except as set forth below,
the global securities may be transferred, in whole and not in part, only to DTC
or another nominee of DTC. Investors may hold their beneficial interests in the
global securities directly through DTC if they have an account with DTC or
indirectly through organizations which have accounts with DTC.

    Notes that are issued as described below under "--Certificated Notes" will
be issued in definitive form. Upon the transfer of notes in definitive form,
such notes will, unless the global securities have previously been exchanged for
notes in definitive form, be exchanged for an interest in the global securities
representing the aggregate principal amount of notes being transferred.

    The description of the operations and procedures of DTC set forth below is
provided solely as a matter of convenience. These operations and procedures are
solely within the control of DTC and are subject to change by DTC from time to
time. The Company takes no responsibility for these operations or procedures,
and investors are urged to contact DTC or its participants directly to discuss
these matters.

    DTC has advised us that it is:

    - a limited purpose trust company organized under the laws of the State of
      New York;

    - a "banking organization" within the meaning of the New York Banking Law;

    - a member of the Federal Reserve System;

    - a "clearing corporation" within the meaning of the New York Uniform
      Commercial Code, as amended; and

    - a "clearing agency" registered under Section 17A of the Exchange Act.

    DTC was created to hold securities for its participants and facilitates the
clearance and settlement of securities transactions between its participants
through electronic book-entry changes to the accounts of its participants, which
eliminates the need for physical transfer and delivery of certificates. DTC's
participants include securities brokers and dealers, including the underwriter;
banks and trust companies; clearing corporations and some other organizations.
Indirect access to DTC's system is also available to other entities such as
banks, brokers, dealers and trust companies; these indirect participants clear
through or maintain a custodial relationship with a participant in DTC, either
directly or indirectly. Investors who are not DTC participants may beneficially
own securities held by or on behalf of DTC only through participants or indirect
participants in DTC.

                                      S-53

    We expect that pursuant to procedures established by DTC:

    - upon the issuance and deposit of the global securities, DTC will credit,
      on its book-entry registrations and transfer system, the aggregate
      principal amount of notes represented by such global securities to the
      accounts of participants in DTC designated by the underwriter with an
      interest in the global securities; and

    - ownership of the notes will be shown on, and the transfer of ownership of
      the notes will be effected only through, records maintained by DTC, with
      respect to the interests of participants in DTC, and the records of
      participants and indirect participants, with respect to the interests of
      persons other than participants in DTC.

    The laws of some jurisdictions may require that some purchasers of
securities take physical delivery of the securities in definitive form.
Accordingly, the ability to transfer interests in the notes represented by a
global note to these persons may be limited. In addition, because DTC can act
only on behalf of its participants, who in turn act on behalf of persons who
hold interests through participants, the ability of a person having an interest
in notes represented by a global note to pledge or transfer that interest to
persons or entities that do not participate in DTC's system, or to otherwise
take actions in respect of that interest, may be affected by the lack of a
physical definitive security in respect of the interest.

    So long as DTC or its nominee is the registered owner of a global note, DTC
or the nominee, as the case may be, will be considered the sole owner or holder
of the notes represented by the global note for all purposes under the
indenture. Except as provided below, owners of beneficial interests in a global
note:

    - will not be entitled to have notes represented by the global note
      registered in their names;

    - will not receive or be entitled to receive physical delivery of
      certificated notes; and

    - will not be considered the owners or holders of the notes under the
      indenture for any purpose, including with respect to the giving of any
      direction, instruction or approval to the trustee under the indenture.

    Accordingly, each holder owning a beneficial interest in a global note must
rely on the procedures of DTC and, if the holder is not a participant or an
indirect participant in DTC, on the procedures of the DTC participant through
which the holder owns its interest, to exercise any rights of a holder of notes
under the indenture or the global note. We understand that under existing
industry practice, if we request any action of holders of notes, or a holder
that is an owner of a beneficial interest in a global note desires to take any
action that DTC, as the holder of the global note, is entitled to take, then DTC
would authorize its participants to take the action and the participants would
authorize holders owning through participants to take the action or would
otherwise act upon the instruction of such holders. Neither the Company nor the
trustee will have any responsibility or liability for any aspect of the records
relating to or payments made on account of notes by DTC, or for maintaining,
supervising or reviewing any records of DTC relating to the notes.

    Payments with respect to the principal of, and premium, if any, and interest
on, any notes represented by a global note registered in the name of DTC or its
nominee on the applicable record date will be payable by the trustee to or at
the direction of DTC or its nominee in its capacity as the registered holder of
the global note representing those notes under the indenture. Under the terms of
the indenture, the Company and the trustee may treat the persons in whose names
the notes, including the global notes, are registered as the owners of the notes
for the purpose of receiving payment on the notes and for any and all other
purposes whatsoever. Accordingly, neither the Company nor the trustee

                                      S-54

has or will have any responsibility or liability for the payment of amounts to
owners of beneficial interests in a global note, including principal, premium,
if any, and interest. Payments by the participants and the indirect participants
in DTC to the owners of beneficial interests in a global note will be governed
by standing instructions and customary industry practice and will be the
responsibility of the participants or the indirect participants and DTC.

    Transfers between participants in DTC will be effected in accordance with
DTC's procedures, and will be settled in same-day funds.

    Although DTC has agreed to the above procedures to facilitate transfers of
interests in the global notes among participants in DTC, it is under no
obligation to perform or to continue to perform the procedures, and the
procedures may be discontinued at any time. Neither the Company nor the trustee
will have any responsibility for the performance by DTC or its participants or
indirect participants of their respective obligations under the rules and
procedures governing their operations.

Certificated Notes

    If:

    - DTC notifies the Company that DTC is at any time unwilling or unable to
      continue as a depositary or DTC ceases to be registered as a clearing
      agency under the Exchange Act and a successor depositary is not appointed
      within 90 days of such notice or cessation;

    - the Company, at its option, notifies the trustee in writing that it elects
      to cause the issuance of notes in definitive form under the indenture; or

    - upon the occurrence of some other events as provided in the indenture;

then, upon surrender by DTC of the global notes, certificated notes will be
issued to each person that DTC identifies as the beneficial owner of the notes
represented by the global notes. Upon the issuance of certificated notes, the
trustee is required to register the certificated notes in the name of that
person or persons, or their nominee, and cause the certificated notes to be
delivered thereto.

    Neither the Company nor the trustee will be liable for any delay by DTC or
any participant or indirect participant in DTC in identifying the beneficial
owners of the related notes and each of those persons may conclusively rely on,
and will be protected in relying on, instructions from DTC for all purposes,
including with respect to the registration and delivery, and the respective
principal amounts, of the notes to be issued.

                                      S-55

                                  UNDERWRITING

    Subject to the terms and conditions set forth in the underwriting agreement
dated October 11, 2001, we have agreed to sell to the underwriter named below,
and the underwriter has agreed to purchase, the principal amount of the notes
set forth opposite its name below:



Underwriter                                                   Principal Amount of Notes
-----------                                                   -------------------------
                                                           
J.P. Morgan Securities Inc..................................         $65,000,000
                                                                     -----------
  Total.....................................................         $65,000,000
                                                                     ===========


    Under the terms and conditions of the underwriting agreement, if the
underwriter takes any of the notes, then the underwriter is obligated to take
and pay for all of the notes.

    The notes will not have an established trading market and will not be listed
on any national securities exchange. The underwriter has advised us that it
intends to make a market in the notes, but it has no obligation to do so and may
discontinue market making at any time without providing notice. No assurance can
be given as to the liquidity of any trading market for the notes.

    The underwriter initially proposes to offer part of the notes directly to
the public at the offering price described on the cover page and part to certain
dealers at a price that represents a concession not in excess of .375% of the
principal amount of the notes. The underwriter may allow, and any such dealer
may reallow, a concession not in excess of .20% of the principal amount of the
notes to certain other dealers. After the initial offering of the notes, the
underwriter may from time to time vary the offering price and other selling
terms.

    We have also agreed to indemnify the underwriter against certain
liabilities, including liabilities under the Securities Act of 1933, as amended,
or to contribute to payments which the underwriter may be required to make
respect of any such liabilities.

    The underwriter will represent and agree that: (i) it has not offered or
sold and will not offer or sell any notes to persons in the United Kingdom
except to persons whose ordinary activities involve them in acquiring, holding,
managing or disposing of investments (as principal or agent) for the purpose of
their businesses or otherwise in circumstances which have not resulted and will
not result in an offer to the public in the United Kingdom with the meaning of
the Public Offers of Securities Regulations 1995; (ii) it has complied and will
comply with all applicable provisions of the Financial Services Act 1986 with
respect to anything done by it in relation to the notes in, from or otherwise
involving the United Kingdom; and (iii) it has only issued or passed on and will
only issue or pass on to any person in the United Kingdom any document received
by it in connection with the offer of the notes if that person is of the kind
described in Article 11(3) of the Financial Services Act 1986 (Investment
Advertisements) (Exemptions) Order 1996, as amended or is a person to whom the
document may otherwise lawfully be issued or passed on.

    In connection with the offering of the notes, the underwriter may engage in
overallotment, stabilizing transactions and syndicate covering transactions.
Overallotment involves sales in excess of the offering size, which creates a
short position for the underwriter. Stabilizing transactions involve bids to
purchase the notes in the open market for the purpose of pegging, fixing or
maintaining the price of the notes. Syndicate covering transactions involve
purchases of the notes in the open market after the distribution has been
completed in order cover short positions. Stabilizing transactions and syndicate
covering transactions may cause the price of notes to be higher than it would
otherwise be in the

                                      S-56

absence of those transactions. If the underwriter engages in stabilizing or
syndicate covering transactions, it may discontinue them at any time.

    The distribution of this prospectus supplement and the accompanying
prospectus and the offering of the notes may, in certain jurisdictions, be
restricted by law. We and the underwriter require from the persons who receive
this prospectus supplement and the accompanying prospectus to inform themselves
of and observe all those restrictions. Neither we nor the underwriter accepts
any legal responsibility for any violation by any person.

    The underwriter and its affiliates have performed and expect to perform in
the future various financial advisory, investment banking and commercial banking
services for us and our affiliates. J.P. Morgan Securities Inc. is an affiliate
of The Chase Manhattan Bank, which is global administrative agent and a lender
to us under our U.S. credit facility and global administrative agent under our
Canadian credit facility; it is an affiliate of The Chase Manhattan Bank of
Canada, which is Canadian administrative agent under our Canadian credit
facility; and it is an affiliate of The Chase Manhattan Bank, Toronto Branch,
which is a lender to us under our Canadian credit facility.

                 CERTAIN UNITED STATES FEDERAL TAX CONSEQUENCES

    The following is a summary of certain United States federal income and
estate tax considerations relating to the purchase, ownership and disposition of
the notes, but does not purport to be a complete analysis of all the potential
tax considerations relating thereto. This summary is based upon the Internal
Revenue Code of 1986 as amended (the "Code") and regulations, rulings and
decisions thereunder now in effect (or, in the case of certain United States
Treasury Regulations, now in proposed form), all of which are subject to change,
possibly on a retroactive basis. This summary deals only with holders that will
hold the notes as "capital assets" (generally, property held for investment) and
does not address tax considerations applicable to investors that may be subject
to special tax rules, including financial institutions, tax-exempt
organizations, insurance companies, dealers in securities or currencies, traders
in securities that elect to use a mark-to-market method of accounting for their
securities holdings, persons that will hold the notes as a position in a hedging
transaction, "straddle" or "conversion transaction" for tax purposes, regulated
investment companies, real estate investment trusts, or persons that have a
"functional currency" other than the U.S. dollar. If a partnership holds the
notes, the tax treatment of a partner will generally depend upon the status of
the partner and the activities of the partnership. If you are a partner of a
partnership holding our notes, you should consult your tax advisor. This summary
discusses the tax considerations applicable only to those purchasers who
purchase the notes in the initial offering at their "issue price" and does not
discuss the tax considerations applicable to other purchasers of the notes.
Moreover, this summary does not discuss alternative minimum tax consequences, if
any, or any state, local or foreign tax consequences to holders of the notes. We
have not sought any ruling from the Internal Revenue Service (the "IRS") with
respect to the statements made and the conclusions reached in the following
summary, and there can be no assurance that the IRS will agree with these
statements and conclusions. INVESTORS CONSIDERING THE PURCHASE OF NOTES SHOULD
CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE UNITED
STATES FEDERAL INCOME AND ESTATE TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL
AS ANY TAX CONSEQUENCES ARISING UNDER THE LAWS OF ANY STATE, LOCAL OR FOREIGN
TAXING JURISDICTION OR UNDER ANY APPLICABLE TAX TREATY.

                                      S-57

United States Holders

    As used in this tax discussion, a "United States Holder" means the
beneficial owner of a note that for United States federal income tax purposes
is:

    (1) a citizen or resident of the United States,

    (2) treated as a domestic corporation,

    (3) an estate the income of which is subject to United States federal income
taxation regardless of its source or

    (4) a trust (i) if it is subject to the supervision of a court within the
United States and one or more United States persons have the authority to
control all substantial decisions of the trust or (ii) that has a valid election
in effect under applicable United States Treasury Regulations to be treated as a
United States person.

PRE-ISSUANCE ACCRUED INTEREST

    A portion of the purchase price of the notes is attributable to the amount
of interest accrued prior to the issue date of the notes. Consequently, the
notes should be treated as having been sold for an amount that excludes any
pre-issuance accrued interest. If the notes are so treated, a portion of the
first stated interest payment equal to any excluded pre-issuance accrued
interest will be treated as a return of such pre-issuance accrued interest and
will not be taxable as interest on the notes.

PAYMENT OF INTEREST

    Interest on a note generally will be includable in your income as ordinary
income at the time the interest is received or accrued, in accordance with your
method of accounting for United States federal income tax purposes.

SALE, EXCHANGE OR REDEMPTION OF THE NOTES

    Upon the sale, exchange or redemption of a note, you generally will
recognize capital gain or loss equal to the difference between:

    (1) the amount of cash proceeds and the fair market value of any property
received on the sale, exchange or redemption (except to the extent this amount
is attributable to accrued interest income, which, except as described above, is
taxable as ordinary income) and

    (2) your adjusted tax basis in the note.

    Your adjusted tax basis in a note generally will equal the amount you paid
for the note, less any principal payments received by you. The gain or loss will
be long-term capital gain or loss if you held the note for more than one year.
Long-term capital gains of individuals, estates and trusts are generally taxed
at a maximum rate of 20%. The deductibility of capital losses is subject to
certain limitations.

INFORMATION REPORTING AND BACKUP WITHHOLDING TAX

    In general, information reporting requirements will apply to certain
non-corporate United States Holders with respect to payments of principal and
interest on a note and to the proceeds of the sale of a note, and a backup
withholding tax also may apply to these payments. If you are such a United
States Holder, you generally will be subject to backup withholding unless you
provide to us or our paying

                                      S-58

agent a correct taxpayer identification number and certain other information,
certified under penalties of perjury, or you otherwise establish an exemption.

    Any amounts withheld from a payment under the backup withholding rules may
be allowed as a credit against your United States federal income tax liability
and may entitle you to a refund, provided that the required information is
furnished to the IRS.

Non-United States Holders

    As used in this tax discussion, a non-United States Holder means any
beneficial owner of a note that is not a United States Holder. The rules
governing the United States federal income and estate taxation of a non-United
States Holder are complex, and no attempt will be made herein to provide more
than a summary of those rules. Special rules may apply to a non-United States
Holder that is a controlled foreign corporation, passive foreign investment
company or foreign personal holding company and therefore subject to special
treatment under the Code. NON-UNITED STATES HOLDERS SHOULD CONSULT WITH THEIR
OWN TAX ADVISORS TO DETERMINE THE EFFECT OF FEDERAL, STATE, LOCAL AND FOREIGN
TAX LAWS WITH REGARD TO AN INVESTMENT IN THE NOTES, INCLUDING ANY REPORTING
REQUIREMENTS.

PAYMENT OF INTEREST

    Generally, payments of interest on a note will qualify for the "portfolio
interest" exemption and, therefore, will not be subject to United States federal
income tax or withholding tax, provided that this interest income is not
effectively connected with a United States trade or business conducted by you
and provided that you:

    (1) do not actually or constructively own 10% or more of the combined voting
power of all classes of our stock entitled to vote,

    (2) are not, for United States federal income tax purposes, a controlled
foreign corporation related to us through stock ownership,

    (3) are not a bank receiving interest on a loan entered into in the ordinary
course of your business within the meaning of Section 881(c)(3)(A) of the Code,
and

    (4) you appropriately certify as to your foreign status.

    You can generally meet the certification requirement by providing a properly
executed Form W-8BEN or appropriate substitute form to us, or our paying agent.
If you hold the notes through a financial institution or other agent acting on
your behalf, you may be required to provide appropriate certifications to the
agent. Your agent will then generally be required to provide appropriate
certifications to us or our paying agent, either directly or through other
intermediaries. Special rules apply to foreign partnerships, estates and trusts,
and in certain circumstances certifications as to the foreign status of
partners, trust owners or beneficiaries may have to be provided to us or our
paying agent. In addition, special rules apply to qualified intermediaries that
enter into withholding agreements with the IRS, and such intermediaries
generally are not required to forward any certification forms received from
Non-U.S. Holders.

    Except to the extent that an applicable treaty otherwise provides, a
non-United States Holder generally will be taxed in the same manner as a United
States Holder with respect to interest if the interest income is effectively
connected with a United States trade or business of the non-United States
Holder. Effectively connected interest received by a corporate non-United States
Holder may also, under

                                      S-59

certain circumstances, be subject to an additional "branch profits tax" at a 30%
rate (or, if applicable, a lower treaty rate). Even though this effectively
connected interest is subject to income tax, and may be subject to the branch
profits tax, it is not subject to withholding tax (unless derived through a
partnership) if the non-United States Holder delivers IRS Form W-8ECI (or
successor form) annually to us or our agent.

    Interest income of a non-United States Holder that is not effectively
connected with a United States trade or business and that does not qualify for
the portfolio interest exemption described above will generally be subject to a
withholding tax at a 30% rate (or, if applicable, a lower treaty rate).

SALE, EXCHANGE OR REDEMPTION OF THE NOTES

    You will generally not be subject to United States federal income tax or
withholding tax on any gain realized on the sale, exchange, redemption or other
disposition of a note unless:

    (1) the gain is effectively connected with your conduct of a United States
trade or business,

    (2) you are an individual who has been present in the United States for a
period or periods aggregating 183 days or more during the taxable year of the
disposition, and certain other requirements are met or

    (3) you are subject to tax pursuant to the provisions of the Code applicable
to certain United States expatriates.

CERTAIN U.S. FEDERAL ESTATE TAX CONSIDERATIONS FOR NON-UNITED STATES HOLDERS

    A note beneficially owned by an individual who is not a citizen or resident
of the United States at the time of death will generally not be includable in
the decedent's gross estate for United States federal estate tax purposes,
provided that the beneficial owner did not at the time of death actually or
constructively own 10% or more of the combined voting power of all classes of
our stock entitled to vote, and provided that, at the time of the holder's
death, payments with respect to that note would not have been effectively
connected with the holder's conduct of a trade or business within the United
States.

INFORMATION REPORTING AND BACKUP WITHHOLDING TAX

    United States information reporting requirements and backup withholding tax
generally will not apply to payments of interest and principal on a note to a
non-United States Holder if the statement described in "Non-United States
Holders--Payment of Interest" is duly provided by the holder or the holder
otherwise establishes an exemption, provided that we do not have actual
knowledge that the holder is a United States person.

    Information reporting requirements and backup withholding tax generally will
not apply to any payment of the proceeds of the sale of a note effected outside
the United States by a foreign office of a "broker" (as defined in applicable
United States Treasury Regulations). However, if the broker:

    (1) is a United States person,

    (2) derives 50% or more of its gross income from all sources for certain
periods from the conduct of a United States trade or business,

    (3) is a controlled foreign corporation as to the United States, or

                                      S-60

    (4) is a foreign partnership in which one or more United States persons, in
the aggregate, own more than 50% of the income or capital interests in the
partnership or is a foreign partnership that is engaged in a trade or business
in the United States,

payment of the proceeds will be subject to information reporting requirements
unless the broker has documentary evidence in its records that the beneficial
owner is a non-United States Holder and certain other conditions are met, or the
beneficial owner otherwise establishes an exemption.

    Payment of the proceeds of any sale of a note to or through the United
States office of a foreign or U.S. broker is subject to information reporting
and backup withholding requirements, unless the beneficial owner of the note
provides the statement described in "Non-United States Holders--Payment of
Interest" or otherwise establishes an exemption and the broker does not have
actual knowledge that the payee is a United States person or that the exemption
conditions are not satisfied.

    Any amounts withheld from a payment to a non-United States Holder under the
backup withholding rules generally will be allowed as a credit against the
non-United States Holder's United States federal income tax liability and may
entitle the non-United States Holder to a refund, provided that the required
information is provided to the IRS.

    THE FEDERAL TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL
INFORMATION ONLY AND MAY NOT BE APPLICABLE DEPENDING UPON A HOLDER'S PARTICULAR
SITUATION. HOLDERS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE TAX
CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE NOTES,
INCLUDING THE TAX CONSEQUENCES UNDER STATE, LOCAL, FOREIGN AND OTHER TAX LAWS
AND THE POSSIBLE EFFECTS OF CHANGES IN FEDERAL OR OTHER TAX LAWS.

             CAUTIONARY STATEMENT ABOUT FORWARD-LOOKING STATEMENTS

    This prospectus and the documents we incorporate by reference contain
statements that constitute "forward-looking statements" within the meaning of
Section 27A of the Securities Act and Section 21E of the Securities Exchange
Act. These statements appear in a number of places in this prospectus and the
documents we incorporate by reference and include statements regarding our
plans, beliefs or current expectations, including those plans, beliefs and
expectations of our officers and directors with respect to, among other things:

    - budgeted capital expenditures;

    - increases in oil and gas production;

    - our outlook on oil and gas prices;

    - estimates of our oil and gas reserves;

    - our future financial condition or results of operations; and

    - our business strategy and other plans and objectives for future
      operations.

    Although we believe that the expectations reflected in such forward-looking
statements are reasonable, any such forward-looking statements are not
assurances of future performance and involve risks and uncertainties. Certain
risks and uncertainties could cause our actual results to differ materially from
anticipated results contained in any forward-looking statements. Prices for oil
and natural gas fluctuate widely. Numerous uncertainties are inherent in
estimating proved oil and natural gas reserves and in projecting future rates of
production and timing of development expenditures. Many of these uncertainties
are beyond our control. Reserve engineering is a subjective process of
estimating underground accumulations of oil and natural gas that cannot be
measured in an exact way. The accuracy of any reserve estimate depends on the
quality of available data and the interpretation of such data by geological
engineers. As a result, estimates made by different engineers often vary from
one another. In addition, the results of drilling, testing and production
activities may justify revisions of estimates that were made previously. If
significant, such revisions would change the schedule of any further production
and development drilling. Accordingly, reserve estimates are generally different
from the quantities of oil and natural gas that are ultimately recovered. Other
factors include:

    - drilling results;

    - oil and gas prices;

    - industry conditions;

    - the prices of goods and services;

    - the availability of drilling rigs and other support services; and

    - the availability of capital resources.

    The information contained in this prospectus, and the documents incorporated
by reference into this prospectus, identify additional factors that could affect
our operating results and performance. We urge you to carefully consider those
factors.

    All forward-looking statements attributable to our company are expressly
qualified in their entirety by this cautionary statement.

                                  THE COMPANY

    Forest Oil Corporation is an independent oil and gas company. We are engaged
in the acquisition, exploration, development, production and marketing of
natural gas and liquids. Forest was incorporated in New York in 1924, the
successor to a company formed in 1916, and has been a publicly held company
since 1969. The Anschutz Corporation, a private Denver-based corporation
currently owns approximately 37% of our common stock. Forest's principal
reserves and producing properties are located in North America. In the United
States, we have business units operating in three areas: offshore Gulf of
Mexico, onshore Gulf of Mexico, and the Western United States. Our fourth
business unit is in Canada, where our oil and gas operations are conducted by
our wholly owned subsidiary, Canadian Forest Oil Ltd. Our fifth business unit
consists of interests in various other countries, including Thailand, South
Africa, Italy, Switzerland and Tunisia; activity in these areas has, to date,
been exploratory in nature and is conducted by our wholly owned subsidiary,
Forest Oil International.

    Our principal executive offices are located at 1600 Broadway, Suite 2200,
Denver Colorado, 80202, and our telephone number at our offices is
(303) 812-1400.

                                USE OF PROCEEDS

    Unless otherwise provided in a prospectus supplement, we will use the net
proceeds from the sale of the securities offered by this prospectus and any
prospectus supplement for general corporate purposes, which may include
repayment of indebtedness, the financing of capital expenditures, future
acquisitions and additions to our working capital.

                       RATIO OF EARNINGS TO FIXED CHARGES

    A description of our company's ratio of earnings to fixed charges or
earnings to combined fixed charges and preferred stock dividends, as applicable,
on a consolidated basis, will appear in an applicable Prospectus Supplement.

                         DESCRIPTION OF DEBT SECURITIES

    Any debt securities issued using this prospectus ("Debt Securities") will be
our direct unsecured general obligations. The Debt Securities will be either
senior debt securities ("Senior Debt Securities") or subordinated debt
securities ("Subordinated Debt Securities").

    The Senior Debt Securities and the Subordinated Debt Securities will be
issued under separate indentures between our company and a U.S. banking
institution (a "Trustee"). The Trustee for each series of Debt Securities will
be identified in the applicable prospectus supplement. Senior Debt Securities
will be issued under a "Senior Indenture" and Subordinated Debt Securities will
be issued under a "Subordinated Indenture." Together the Senior Indenture and
the Subordinated Indenture are called "Indentures."

    The Debt Securities may be issued from time to time in one or more series.
The particular terms of each series that is offered by a prospectus supplement
will be described in the prospectus supplement.

    We have summarized selected provisions of the Indentures below. The summary
is not complete. The forms of the Indentures have been filed as exhibits to the
registration statement and you should read the Indentures for provisions that
may be important to you. In the summary below, we have included references to
section numbers of the applicable Indentures so that you can easily locate these
provisions. Whenever we refer in this prospectus or in the prospectus supplement
to particular sections or defined terms of the Indentures, such sections or
defined terms are incorporated by reference herein

                                       5

or therein, as applicable. Capitalized terms used in this summary have the
meanings specified in the Indentures.

General

    The Indentures provide that Debt Securities in separate series may be issued
from time to time without limitation as to aggregate principal amount. We may
specify a maximum aggregate principal amount for the Debt Securities of any
series. (Section 301) We will determine the terms and conditions of the Debt
Securities, including the maturity, principal and interest, but those terms must
be consistent with the applicable Indenture.

    The Senior Debt Securities will rank equally with all of our other senior
unsecured and unsubordinated debt ("Senior Debt"). The Subordinated Debt
Securities will be subordinated in right of payment to the prior payment in full
of all of our Senior Debt as described under "--Subordination of Subordinated
Debt Securities" and in the prospectus supplement applicable to any Subordinated
Debt Securities.

    A prospectus supplement and a supplemental indenture relating to any series
of Debt Securities being offered will include specific terms related to the
offering, including the price or prices at which the Debt Securities to be
offered will be issued. These terms will include some or all of the following:

    - the title of the Debt Securities;

    - whether the Debt Securities are Senior Debt Securities or Subordinated
      Debt Securities;

    - the total principal amount of the Debt Securities;

    - the dates on which the principal of the Debt Securities will be payable;

    - the interest rate of the Debt Securities and the interest payment dates
      for the Debt Securities;

    - the places where payments on the Debt Securities will be payable;

    - any terms upon which the Debt Securities may be redeemed at our option;

    - any sinking fund or other provisions that would obligate our company to
      repurchase or otherwise redeem the Debt Securities;

    - whether the Debt Securities are defeasible;

    - any addition to or change in the Events of Default;

    - if convertible into our common stock or any of our other securities, the
      terms on which such Debt Securities are convertible;

    - any addition to or change in the covenants in the applicable Indenture;
      and

    - any other terms of the Debt Securities not inconsistent with the
      provisions of the applicable Indenture. (Section 301)

    The Indentures do not limit the amount of Debt Securities that may be
issued. Each Indenture allows Debt Securities to be issued up to the principal
amount that may be authorized by our company and may be in any currency or
currency unit designated by us.

    If so provided in the applicable prospectus supplement, we may issue the
Debt Securities at a discount below their principal amount and pay less than the
entire principal amount of the Debt Securities upon declaration of acceleration
of their maturity ("Original Issue Discount Securities"). The

                                       6

applicable prospectus supplement will describe all material U.S. federal income
tax, accounting and other considerations applicable to Original Issue Discount
Securities.

Senior Debt Securities

    The Senior Debt Securities will be unsecured senior obligations and will
rank equally with all other senior unsecured and unsubordinated debt. The Senior
Debt Securities will, however, be subordinated in right of payment to all our
secured indebtedness to the extent of the value of the assets securing such
indebtedness. Except as provided in the applicable Senior Indenture or specified
in any authorizing resolution or supplemental indenture relating to a series of
Senior Debt Securities to be issued, no Senior Indenture will limit the amount
of additional indebtedness that may rank equally with the Senior Debt Securities
or the amount of indebtedness, secured or otherwise, that may be incurred or
preferred stock that may be issued by any of our subsidiaries.

Subordination of Subordinated Debt Securities

    Under the Subordinated Indenture, payment of the principal, interest and any
premium on the Subordinated Debt Securities will generally be subordinated in
right of payment to the prior payment in full of all of our Senior Debt,
including any Senior Debt Securities. The prospectus supplement relating to any
Subordinated Debt Securities will summarize the subordination provisions of the
Subordinated Indenture applicable to that series, including:

    - the applicability and effect of such provisions upon any payment or
      distribution of our assets to creditors upon any liquidation, bankruptcy,
      insolvency or similar proceedings;

    - the applicability and effect of such provisions in the event of specified
      defaults with respect to Senior Debt, including the circumstances under
      which and the periods in which we will be prohibited from making payments
      on the Subordinated Debt Securities; and

    - the definition of Senior Debt applicable to the Subordinated Debt
      Securities of that series.

    The failure to make any payment on any of the Subordinated Debt Securities
due to the subordination provisions of the Subordinated Indenture described in
the prospectus supplement will not prevent the occurrence of an Event of Default
under the Subordinated Debt Securities.

Conversion Rights

    The Debt Securities may be converted into other securities of our company,
if at all, according to the terms and conditions of an applicable prospectus
supplement. Such terms will include the conversion price, the conversion period,
provisions as to whether conversion will be at the option of the holders of such
series of Debt Securities or at the option of our company, the events requiring
an adjustment of the conversion price and provisions affecting conversion in the
event of the redemption of such series of Debt Securities.

Form, Exchange and Transfer

    The Debt Securities of each series will be issuable only in fully registered
form, without coupons. Unless otherwise indicated in the applicable prospectus
supplement, the securities will be issued in denominations of $1,000 each or
multiples thereof. (Section 302)

    Subject to the terms of the applicable Indenture and the limitations
applicable to global securities, Debt Securities may be transferred or exchanged
at the corporate trust office of the Trustee or at any

                                       7

other office or agency maintained by our company for such purpose, without the
payment of any service charge except for any tax or governmental charge.
(Sections 305 and 1002)

Global Securities

    The Debt Securities of any series may be issued, in whole or in part, by one
or more global certificates that will be deposited with a depositary identified
in the applicable prospectus supplement.

    No global security may be exchanged in whole or in part for Debt Securities
registered in the name of any person other than the depositary for such global
security or any nominee of such depositary unless:

    - the depositary is unwilling or unable to continue as depositary;

    - an Event of Default has occurred and is continuing; or

    - as otherwise provided in a prospectus supplement.

    Unless otherwise stated in any prospectus supplement, The Depository Trust
Company ("DTC") will act as depository. Beneficial interests in global
certificates will be shown on, and transfers of global certificates will be
affected only through records maintained by DTC and its participants.

Payment

    Unless otherwise indicated in the applicable prospectus supplement, payment
of interest on a Debt Security on any interest payment date will be made to the
person in whose name such Debt Security is registered at the close of business
on the regular record date for such interest. (Section 307)

    Unless otherwise indicated in the applicable prospectus supplement,
principal interest and any premium on the Debt Securities will be paid at
designated places. However, at our option, payment may be made by check mailed
to the persons in whose names the Debt Securities are registered on days
specified in the Indenture or any prospectus supplement. (Sections 1002 and
1003)

Consolidation, Merger and Sale of Assets

    We may consolidate with or merge into, or sell or lease substantially all of
our properties to any person if:

    - the successor person (if any) is a corporation, partnership, trust or
      other entity organized and validly existing under the laws of any domestic
      jurisdiction and assumes our obligations on the Debt Securities and under
      the Indentures;

    - immediately after giving effect to the transaction, no Event of Default,
      and no event which, after notice or lapse of time or both, would become an
      Event of Default, shall have occurred and be continuing; and

    - any other conditions specified in the applicable prospectus supplement are
      met. (Section 801)

Events of Default

    Unless otherwise specified in the prospectus supplement, each of the
following will constitute an event of default ("Event of Default") under the
Indentures:

    - failure to pay principal or premium on any Debt Security of that series
      when due;

    - failure to pay any interest on any Debt Security of that series when due,
      continued for 30 days;

                                       8

    - failure to deposit any sinking fund payment, when due, on any Debt
      Security of that series;

    - failure to perform any other covenant or the breach of any warranty in the
      Indenture for 90 days after being given written notice;

    - certain events of bankruptcy, insolvency or reorganization affecting us;
      and

    - any other Event of Default included in the applicable Indenture or
      supplemental indenture. (Section 501)

    If an Event of Default (other than as a result of bankruptcy, insolvency or
reorganization) for any series of Debt Securities occurs and continues, the
Trustee or the holders of at least 25% in aggregate principal amount of the
outstanding Debt Securities of that series may declare the principal amount of
the Debt Securities of that series (or, such portion of the principal amount of
such Debt Securities, as may be specified in a prospectus supplement) to be due
and payable immediately. If an Event of Default results from bankruptcy,
insolvency or reorganization, the principal amount of all the Debt Securities of
a series (or, such portion of the principal amount of such Debt Securities as
may be specified in a prospectus supplement) will automatically become
immediately due and payable. If an acceleration occurs, subject to certain
conditions, the holders of a majority of the aggregate principal amount of the
Debt Securities of that series can rescind the acceleration. (Section 502)

    Other than its duties in case of an Event of Default, a Trustee is not
obligated to exercise any of its rights or powers under the applicable Indenture
at the request of any of the holders, unless the holders offer the Trustee
reasonable indemnity. (Section 603) Subject to the indemnification of the
Trustees, the holders of a majority in aggregate principal amount of the
outstanding Debt Securities of any series may direct the time, method and place
of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power conferred on the Trustee with respect to the Debt
Securities of that series. (Section 512)

    The holders of Debt Securities of any series will not have any right to
institute any proceeding with respect to the applicable Indenture, unless:

    - the holder has given written notice to the Trustee of an Event of Default;

    - the holders of at least 25% in aggregate principal amount of the
      outstanding Debt Securities of that series have made written request, and
      such holder or holders have offered reasonable indemnity, to the Trustee
      to institute such proceeding as trustee; and

    - the Trustee fails to institute such proceeding, and has not received from
      the holders of a majority in aggregate principal amount of the outstanding
      Debt Securities of that series a direction inconsistent with such request,
      within 60 days after such notice, request and offer. (Section 507)

    Such limitations do not apply, however, to a suit instituted by a holder of
a Debt Security for the enforcement of payment of the principal, interest or
premium on such Debt Security on or after the applicable due date specified in
such Debt Security. (Section 508)

    We will be required to furnish to each Trustee annually within 120 days of
the end of each fiscal year a statement by certain of our officers as to whether
or not we are in default in the performance of any of the terms of the
applicable Indenture. (Section 1004)

Modification and Waiver

    Under each Indenture, our rights and obligations and the rights of holders
may be modified with the consent of the holders of a majority in aggregate
principal amount of the outstanding Debt

                                       9

Securities of each series affected by the modification. No modification of the
principal or interest payment terms, and no modification reducing the percentage
required for modifications, is effective against any holder without its consent.

Defeasance and Covenant Defeasance

    If, and to the extent, indicated in the applicable prospectus supplement, we
may elect, at our option at any time, to have the provisions of the Indentures,
relating to defeasance and discharge of indebtedness and to defeasance of
certain restrictive covenants, applied to the Debt Securities of any series, or
to any specified part of a series. (Section 1301)

    DEFEASANCE AND DISCHARGE.  The Indentures provide that, upon the exercise of
our option (if any), we will be discharged from all our obligations with respect
to the applicable Debt Securities upon the deposit in trust for the benefit of
the holders of such Debt Securities of money or U.S. government obligations, or
both, which, through the payment of principal and interest in respect thereof in
accordance with their terms, will provide money in an amount sufficient to pay
the principal of and any premium and interest on such Debt Securities on the
respective stated maturities in accordance with the terms of the applicable
Indenture and such Debt Securities. Any additional conditions to the discharge
of our obligations with respect to a series of Debt Securities will be described
in an applicable prospectus supplement.

    DEFEASANCE OF CERTAIN COVENANTS.  The Indentures provide that, upon the
exercise of our option (if any), we may omit to comply with certain restrictive
covenants described in an applicable prospectus supplement, the occurrence of
certain Events of Default as described in an applicable prospectus supplement
will not be deemed to either be or result in an Event of Default and, if such
Debt Securities are Subordinated Debt Securities, the provisions of the
Subordinated Indenture relating to subordination will cease to be effective, in
each case with respect to such Debt Securities. In order to exercise such
option, we must deposit, in trust for the benefit of the holders of such Debt
Securities, money or U.S. government obligations, or both, which, through the
payment of principal and interest in respect thereof in accordance with their
terms, will provide money in an amount sufficient to pay the principal of and
any premium and interest on such Debt Securities on the respective stated
maturities in accordance with the terms of the applicable Indenture and such
Debt Securities. Any additional conditions to exercising this option with
respect to a series of Debt Securities will be described in an applicable
prospectus supplement. (Sections 1303 and 1304)

Notices

    Notices to holders of Debt Securities will be given by mail to the addresses
of such holders as they may appear in the security register. (Sections 101 and
106)

Title

    We, the Trustees and any agent of ours or a Trustee may treat the person in
whose name a Debt Security is registered as the absolute owner of the Debt
Security, whether or not such Debt Security may be overdue, for the purpose of
making payment and for all other purposes. (Section 308)

Governing Law

    The Indentures and the Debt Securities will be governed by, and construed in
accordance with, the law of the State of New York. (Section 112)

                                       10

                          DESCRIPTION OF CAPITAL STOCK

    Pursuant to our restated certificate of incorporation, our authorized
capital stock consists of 200,000,000 shares of common stock and 10,000,000
shares of preferred stock. As of December 31, 1999, we had 53,809,159 shares of
common stock outstanding, and no shares of preferred stock outstanding.

Common Stock

    Our outstanding shares of common stock are listed on the New York Stock
Exchange under the symbol "FST". Any additional common stock we issue will also
be listed on the NYSE.

    All outstanding shares of common stock are fully paid and non-assessable.
Any additional common stock we issue will also be fully paid and non-assessable.

    Our common shareholders are entitled to one vote per share in the election
of directors and on all other matters submitted to a vote of our common
shareholders. Our common shareholders do not have preemptive or cumulative
voting rights.

    Our common shareholders are entitled to receive ratably any dividends
declared by our board of directors out of funds legally available for the
payment of dividends. Dividends on our common stock are, however, subject to any
preferential dividend rights of outstanding preferred stock. We do not intend to
pay cash dividends on our common stock in the foreseeable future. Upon our
liquidation, dissolution or winding up, our common shareholders are entitled to
receive ratably our net assets available after payment of all of our debts and
other liabilities. Any payment is, however, subject to the prior rights of any
outstanding preferred stock. Our common shareholders do not have any preemptive,
subscription, redemption or conversion rights.

    We will notify common shareholders of any shareholders' meetings according
to applicable law. If we liquidate, dissolve or wind-up our business, either
voluntarily or not, common shareholders will share equally in the assets
remaining after we pay our creditors and preferred shareholders.

Preferred Stock

    The following summary describes certain general terms and provisions of our
authorized preferred stock. If we offer preferred stock, a description will be
filed with the SEC and the specific terms of the preferred stock will be
described in the prospectus supplement, including the following terms:

    - the series, the number of shares offered and the liquidation value of the
      preferred stock;

    - the price at which the preferred stock will be issued;

    - the dividend rate, the dates on which the dividends will be payable and
      other terms relating to the payment of dividends on the preferred stock;

    - the liquidation preference of the preferred stock;

    - the voting rights of the preferred stock;

    - whether the preferred stock is redeemable or subject to a sinking fund,
      and the terms of any such redemption or sinking fund;

    - whether the preferred stock is convertible or exchangeable for any other
      securities, and the terms of any such conversion; and

                                       11

    - any additional rights, preferences, qualifications, limitations and
      restrictions of the preferred stock.

    Our restated certificate of incorporation allows our board of directors to
issue preferred stock from time to time in one or more series, without any
action being taken by our shareholders. The board can also determine the number
of shares of each series. Subject to the provisions of our restated certificate
of incorporation and limitations prescribed by law, our board of directors may
adopt resolutions to issue shares of a series of our preferred stock, and
establish their terms. These terms may include:

    - voting powers;

    - designations;

    - preferences;

    - dividend rights;

    - dividend rates;

    - terms of redemption;

    - redemption process;

    - conversion rights; and

    - any other terms permitted to be established by our certificate of
      incorporation and by applicable law.

    In some cases, the issuance of preferred stock could delay a change in
control of the company and make it harder to remove present management. Under
certain circumstances, preferred stock could also restrict dividend payments to
holders of our common stock.

    The preferred stock will, when issued, be fully paid and non-assessable.

Anti-Takeover Provisions

    Certain provisions in our restated certificate of incorporation, by-laws,
shareholders' rights plan and the New York Business Corporation Law ("NYBCL")
may have the effect of encouraging persons considering unsolicited tender offers
or other unilateral takeover proposals to negotiate with our board of directors
rather than pursue non-negotiated takeover attempts.

    BLANK CHECK PREFERRED STOCK.  Our restated certificate of incorporation
authorizes the issuance of blank check preferred stock. Our board of directors
can set the voting, redemption, conversion and other rights relating to such
preferred stock and can issue such stock in either a private or public
transaction. The issuance of preferred stock, while providing desired
flexibility in connection with possible acquisitions and other corporate
purposes, could adversely affect the voting power of holders of common stock and
the likelihood that holders will receive dividend payments and payments upon
liquidation and could have the effect of delaying, deferring or preventing a
change in control of our company. In some circumstances, the blank check
preferred stock could be issued and have the effect of preventing a merger,
tender offer or other takeover attempt which our board of directors opposes.

    SHAREHOLDERS' RIGHTS AGREEMENT.  Our board of directors has adopted a
shareholders' rights plan. Under the rights plan, each share of common stock
includes a preferred stock purchase right (the Rights). Each right entitles the
registered holder under the circumstances described below to purchase from our
company one one-hundredth of a share of our First Series Junior Preferred Stock,
par value $0.01 per share (the "preferred shares"), at a price of $30 per one
one-hundredth of a preferred share,

                                       12

subject to adjustment. The following is a summary of certain terms of the rights
agreement. The rights agreement is filed as an exhibit to the registration
statement of which this prospectus is a part, and this summary is qualified by
reference to the specific terms of the rights agreement.

    Until the distribution date, the rights attach to all common stock
certificates representing outstanding shares. No separate right certificate will
be distributed. A right is issued for each share of common stock issued. The
rights will separate from the common stock and a distribution date will occur
upon the earlier of

    - 10 business days following a public announcement that a person or group of
      affiliated or associated persons has acquired beneficial ownership of 20%
      or more of our outstanding common stock; or

    - 10 business days following the commencement or announcement of an
      intention to commence a tender offer or exchange offer the completion of
      which would result in the beneficial ownership by a person or group of 20%
      or more of our outstanding common stock.

    Until the distribution date or the earlier of redemption or expiration of
the rights, the rights will be evidenced by the certificates representing the
common stock with a copy of a summary of such rights attached thereto. As soon
as practicable following the distribution date, separate certificates evidencing
the rights will be mailed to holders of record of the common stock as of the
close of business on the distribution date and such separate rights certificates
alone will thereafter evidence the rights.

    The rights are not exercisable until the distribution date. The rights will
expire on October 29, 2003, unless the expiration date is extended or the rights
are earlier redeemed or exchanged.

    If a person or group acquires 20% or more of our voting stock, each right
then outstanding, other than rights beneficially owned by the acquiring persons,
which would become null and void, becomes a right to buy that number of shares
of common stock, or under certain circumstances, the equivalent number of one
one-hundredths of a preferred share, that at the time of such acquisition has a
market value of two times the purchase price of the right.

    If we are acquired in a merger or other business combination transaction or
assets constituting more than 50% of our consolidated assets or producing more
than 50% of our earning power or cash flow are sold, proper provision will be
made so that each holder of a right will thereafter have the right to receive,
upon the exercise thereof at the then current purchase price of the right, that
number of shares of common stock of the acquiring company that at the time of
such transaction has a market value of two times the exercise price of the
right.

    The dividend and liquidation rights, and the non-redemption feature, of the
preferred shares are designed so that the value of one one-hundredth of a
preferred share purchasable upon exercise of each right will approximate the
value of one share of common stock. The preferred shares issuable upon exercise
of the rights will be non-redeemable and rank junior to all other series of our
preferred stock. Each whole preferred share will be entitled to receive a
quarterly preferential dividend in an amount per share equal to the greater of
(a) $1.00 in cash, or (b) 100 times the aggregate per share dividend declared on
the common stock. In the event of liquidation, the holders of preferred shares
will be entitled to receive a preferential liquidation payment per whole share
equal to the greater of (a) $100 per share, or (b) 100 times the aggregate
amount to be distributed per share of common stock. In the event of any merger,
consolidation or other transaction in which the shares of common stock are
exchanged for or changed into other stock or securities, cash or other property,
each whole preferred share will be entitled to 100 times the amount received per
share of common stock. Each whole

                                       13

preferred share will be entitled to 100 votes on all matters submitted to a vote
of our shareholders', and preferred shares will generally vote together as one
class with the common stock and any other capital stock on all matters submitted
to a vote of our shareholders'.

    The purchase price and the number of one one-hundredths of a preferred share
or other securities or property issuable upon exercise of the rights may be
adjusted from time to time to prevent dilution.

    At any time after a person or group of affiliated or associated persons
acquires beneficial ownership of 20% or more of our outstanding voting stock and
before a person or group acquires beneficial ownership of 50% or more of our
outstanding voting stock, our board of directors may, at its option, issue
common stock in mandatory redemption of, and in exchange for, all or part of the
then outstanding exercisable rights, other than rights owned by such person or
group, which would become null and void, at an exchange ratio of one share of
common stock, or one one-hundredth of a preferred share, for each two shares of
common stock for which each right is then exercisable, subject to adjustment.

    At any time prior to the acquisition by a person or group of beneficial
ownership of 20% or more of the outstanding common stock, our board of directors
may redeem all, but not less than all, the then outstanding rights at a price of
$0.01 per right. The redemption of the rights may be made effective at such
time, on such basis and with such conditions as our board of directors in its
sole discretion may establish. Immediately upon the action of our board of
directors ordering redemption of the rights, the right to exercise the rights
will terminate and the only right of the holders of rights will be to receive
the redemption price.

    BUSINESS COMBINATIONS UNDER NEW YORK LAW.  We are a New York corporation and
are subject to the New York Business Corporation Law ("NYBCL"). The business
combination provisions of Section 912 of the NYBCL could prohibit or delay
mergers or other takeovers or change in control attempts with respect to our
company and, accordingly, may discourage attempts to acquire our company. In
general such provisions prohibit an interested shareholder (i.e., a person who
owns 20% or more of our outstanding voting stock) from engaging in various
business combination transactions with our company, unless (a) the business
combination transaction, or the transaction in which the interested shareholder
became an interested shareholder, was approved by the board of directors prior
to the interested shareholder's stock acquisition date, (b) the business
combination transaction was approved by the disinterested shareholders at a
meeting called no earlier than five years after the interested shareholder's
stock acquisition date, or (c) if the business combination transaction takes
place no earlier than five years after the interested shareholder's stock
acquisition date, the price paid to all the shareholders under such transaction
meets statutory criteria.

    A business combination is defined by Section 912 of the NYBCL as including
various transactions between the corporation and an interested shareholder,
including mergers, consolidations, transfers of assets (whether by sale, lease,
exchange, mortgage, pledge, transfer or otherwise), certain share issuances,
liquidation or dissolution, certain reclassifications of securities and other
transactions resulting in financial benefit to a shareholder.

    A business combination transaction with The Anschutz Corporation is not
prohibited by Section 912 of the NYBCL because the transaction in which The
Anschutz Corporation became the holder of more than 20% of Forest's common stock
was approved by the board of directors.

                       DESCRIPTION OF SECURITIES WARRANTS

    We may issue securities warrants for the purchase of debt securities,
preferred stock, common stock or other securities. Securities warrants may be
issued independently or together with debt securities, preferred stock, or
common stock offered by any prospectus supplement and may be attached to or
separate from any such offered securities. Each series of securities warrants
will be issued under a separate warrant agreement to be entered into between our
company and a bank or trust company, as warrant agent, all as set forth in the
prospectus supplement relating to the particular issue of securities warrants.
The securities warrant agent will act solely as an agent of our company in
connection with the securities warrants and will not assume any obligation or
relationship of agency or trust for or with any holders of securities warrants

    The following summary of certain provisions of the securities warrants does
not purport to be complete and is subject to, and is qualified in its entirety

      price at which such number of units of such other securities may be
      purchased upon such exercise;

    - the date on which the right to exercise such securities warrants shall
      commence and the date on which such right shall expire;

    - United States federal income tax consequences applicable to such
      securities warrants;

    - the amount of securities warrants outstanding as of the most recent
      practicable date; and

    - any other terms of such securities warrants.

for securities warrants will be subject to adjustment in accordance with the
applicable prospectus supplement.

                                       15

    Each securities warrant will entitle the holder thereof to purchase such
principal amount of debt securities or such number of shares of preferred stock,
common stock or other securities at such exercise price as shall in each case be
set forth in, or calculable from, the prospectus supplement relating to the
securities warrants, which exercise price may be subject to adjustment upon the
occurrence of certain events as set forth in such prospectus supplement. After
the close of business on the expiration date, or such later date to which such
expiration date may be extended by us, unexercised securities warrants will
become void. The place or places where, and the manner in which, securities
warrants may be exercised shall be specified in the prospectus supplement
relating to such securities warrants.

    Prior to the exercise of any securities warrants to purchase debt
securities, preferred stock, common stock or other securities, holders of such
securities warrants will not have any of the rights of holders of debt
securities, preferred stock, common stock or other securities, as the case may
be, purchasable upon such exercise, including the right to receive payments of
principal of, premium, if any, or interest, if any, on the debt securities
purchasable upon such exercise or to enforce covenants in the applicable
Indenture, or to receive payments of dividends, if any, on the preferred stock,
or common stock purchasable upon such exercise, or to exercise any applicable
right to vote.

acquired by the underwriters for their own account. The underwriters may resell
the securities in one or more transactions, including negotiated transactions,
at a fixed public offering price or at varying prices determined at the time of
sale. The obligations of the underwriters to purchase the securities will be
subject to certain conditions. Unless indicated in the prospectus supplement the

offering price and any discounts or concessions allowed or re-allowed or paid to
dealers may be changed from time to time.

under such delayed delivery and payment arrangements will be subject to the
condition that the purchase of the offered securities will not at the time of

will not have any responsibility with respect to the validity or performance of
such contracts.

General Information
