(1) This estimate is made pursuant to Rule 457(c) under the Securities Act solely for the purpose of calculating the registration fee. The calculation is based on the average of the bid and asked prices for the LYONs of $853.75 in the PORTAL System on February 12, 2003.
(2) Reflects the number of shares of common stock issuable upon conversion of the LYONs. Each $1,000 principal amount at maturity of a LYON may be converted into 4.7301 shares of common stock, subject to adjustment. Pursuant to Rule 416 under the Securities Act, the number of shares of common stock registered hereby shall include an indeterminate number of shares of common stock that may be issued in connection with a stock split, stock dividend, recapitalization or similar event. No additional registration fee is required pursuant to Rule 457(i) under the Securities Act.
(3) Computed in accordance with Section 6(b) of the Securities Act of 1933, as amended, by multiplying 0.000092 by the proposed maximum aggregate offering price.

The registrant hereby amends this registration statement on such date or dates as may be necessary to delay its effective date until the registrant shall file a further amendment which specifically states that this registration statement shall thereafter become effective in accordance with Section 8(a) of the Securities Act of 1933 or until the registration statement shall become effective on such date as the Commission, acting pursuant to said Section 8(a), may determine.



The information in this prospectus is not complete and may be changed. The selling security holders may not sell these securities until the registration statement filed with the Securities and Exchange Commission is effective. This prospectus is not an offer to sell these securities and it is not soliciting an offer to buy these securities in any state where the offer or sale is not permitted.

PROSPECTUS

$639,000,000

3M COMPANY

LIQUID YIELD OPTION(TM) NOTES DUE 2032
(ZERO COUPON -- SENIOR)

AND SHARES OF COMMON STOCK ISSUABLE UPON CONVERSION
OF THE LIQUID YIELD OPTION(TM) NOTES


THE OFFERING:

We issued $639,000,000 aggregate principal amount at maturity of our Liquid Yield Option Notes due 2032 (Zero Coupon - Senior), or "LYONs", in a private placement on November 21, 2002 at an issue price of $860.87 per LYON (86.087% of the principal amount at maturity). This prospectus covers the resale by holders of the LYONs and shares of our common stock into which the LYONs are convertible. We will not pay interest on the LYONs prior to maturity unless contingent interest becomes payable as described below. Instead, on November 13, 2032, the maturity date of the LYONs, each holder will receive $1,000 per LYON. The issue price of each LYON represents a yield to maturity of 0.5% per year calculated from November 21, 2002, excluding any contingent interest. The LYONs rank equally with all of our existing and future unsecured and unsubordinated indebtedness. We will not receive any proceeds from the resale of the LYONs or the common stock sold under this prospectus.

CONVERTIBILITY OF THE LYONS:

Holders may convert each LYON into 4.7301 shares of our common stock, subject to adjustment, which we refer to as the conversion rate, only (1) if the sale price of our common stock reaches specified thresholds, (2) during any period in which the credit rating assigned to the LYONs is below a specified level, (3) if the LYONs are called for redemption or (4) if specified corporate transactions have occurred. Upon conversion, we will have the right to deliver, in lieu of our common stock, cash or a combination of cash and common stock in an amount described herein. Our common stock is listed on the New York Stock Exchange under the symbol "MMM." On February 13, 2003, the last reported sale price of our common stock on the New York Stock Exchange was $122.41 per share.

CONTINGENT INTEREST:

We will pay contingent cash interest on the LYONs during any six-month period from November 22 to May 21 and from May 22 to November 21, with the initial six-month period commencing November 22, 2007, if the average market price of a LYON for a five day trading measurement period preceding such six-month period equals 130% or more of the sum of the issue price and accrued original issue discount for such LYON as of the day immediately preceding the relevant six-month period. The contingent interest payable per LYON in respect of any quarterly period will be equal to the greater of (1) any regular cash dividends paid by us per share on our common stock during that quarterly period multiplied by the then applicable conversion rate or (2) $0.62 multiplied by
4.7301. For United States Federal income tax purposes, the LYONs will constitute contingent payment debt instruments. You should read the discussion of selected United States Federal income tax considerations relevant to the LYONs beginning on page 25.

PURCHASE OF THE LYONS BY 3M AT THE OPTION OF THE HOLDER:

Holders may require us to purchase all or a portion of their LYONs on November 21, 2005, 2007, 2012, 2017, 2022 and 2027 at prices set forth in "Description of LYONs--Purchase of LYONs by 3M at the Option of the Holder." We may choose to pay the purchase price in cash, our common stock or a combination of cash and our common stock. In addition, upon a change in control, as defined in the indenture, of 3M occurring on or before November 21, 2007, holders may require us to repurchase for cash all or a portion of their LYONs.

REDEMPTION OF THE LYONS AT THE OPTION OF 3M:

We may redeem for cash all or a portion of the LYONs at any time on or after November 21, 2007 at the prices set forth in "Description of LYONs-- Redemption of LYONs at the Option of 3M."

Prior to this offering, the LYONs have been eligible for trading in the Private Offerings, Resales and Trading through Automated Linkages ("PORTAL") system of the National Association of Securities Dealers, Inc. LYONs sold by means of this prospectus are not expected to remain eligible for trading on the PORTAL system. We do not intend to list the LYONs for trading on any national securities exchange or on the Nasdaq National Market.


INVESTING IN THE LYONS INVOLVES RISKS, SOME OF WHICH ARE DESCRIBED IN

THE "RISK FACTORS" SECTION BEGINNING ON PAGE 7 OF THIS PROSPECTUS.

SUMMARY

THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY THE MORE DETAILED INFORMATION INCLUDED ELSEWHERE OR INCORPORATED BY REFERENCE IN THIS PROSPECTUS. BECAUSE THIS IS A SUMMARY, IT MAY NOT CONTAIN ALL THE INFORMATION THAT MAY BE IMPORTANT TO YOU. YOU SHOULD READ THE ENTIRE PROSPECTUS, AS WELL AS THE INFORMATION INCORPORATED BY REFERENCE, BEFORE MAKING AN INVESTMENT DECISION. WHEN USED IN THIS PROSPECTUS, THE TERMS "3M," "3M COMPANY," "WE," "OUR" AND "US" REFER TO 3M COMPANY AND ITS CONSOLIDATED SUBSIDIARIES, UNLESS OTHERWISE SPECIFIED.

3M COMPANY

3M was incorporated in 1929 under the laws of the State of Delaware to continue operations, begun in 1902, of a Minnesota corporation originally named Minnesota Mining and Manufacturing Company. On April 8, 2002, the company's name was changed to 3M Company. 3M's principal executive offices are located at 3M Center, St. Paul, Minnesota 55144 (telephone: 651-733-1110).

3M is an integrated enterprise characterized by substantial intercompany cooperation in research, manufacturing and marketing of products. 3M's business has developed from its research and technology in coating and bonding for coated abrasives, the company's original product. Coating and bonding is the process of applying one material to another, such as abrasive granules to paper or cloth (coated abrasives), adhesives to a backing (pressure-sensitive tapes), ceramic coating to granular mineral (roofing granules), glass beads to plastic backing (reflective sheeting) and low-tack adhesives to paper (repositionable notes).

3M is among the leading manufacturers of products for many of the markets it serves. In all cases, 3M products are subject to direct or indirect competition. Most 3M products involve expertise in product development, manufacturing and marketing, and are subject to competition from products manufactured and sold by other technically oriented companies.

Our strategic business units have been aggregated into six reportable segments: Industrial Markets, Health Care Markets, Transportation, Graphics and Safety Markets, Consumer and Office Markets, Electro and Communications Markets and Specialty Material Markets. These segments bring together common or related 3M technologies, enhancing the development of innovative products and services and providing for efficient sharing of business resources. These segments have worldwide responsibility for virtually all 3M product lines. A few miscellaneous businesses and staff-sponsored products, as well as various corporate assets and corporate overhead expenses, are not assigned to the segments.

THE OFFERING

LYONs..........................    $639,000,000 aggregate principal amount at
                                   maturity of LYONs due November 21, 2032. We
                                   will not pay interest on the LYONs prior to
                                   maturity unless contingent interest becomes
                                   payable as described below. Each LYON was
                                   issued at a price of $860.87 per LYON and has
                                   a principal amount at maturity of $1,000.

Maturity of LYONs..............    November 21, 2032.

Yield to Maturity of LYONs.....    0.5% per year (computed on a semi-annual bond
                                   equivalent basis) calculated from
                                   November 21, 2002, excluding any contingent
                                   interest.

Ranking........................    The LYONs are unsecured and unsubordinated
                                   obligations of 3M and rank equally in right
                                   of payment to all our existing and future
                                   unsecured and unsubordinated indebtedness.
                                   However, a significant portion of 3M's
                                   business is conducted through subsidiaries;
                                   and, because claims by creditors of those
                                   subsidiaries would be senior to 3M's equity
                                   interests in such subsidiaries, indebtedness
                                   of 3M, including the LYONs, is structurally
                                   subordinated to the claims of such creditors.
                                   As of December 31, 2002 we had approximately
                                   $3,377 million of consolidated senior
                                   indebtedness outstanding.

Original Issue Discount........    We offered the LYONs at an issue price
                                   significantly below the principal amount at
                                   maturity of the LYONs. The difference between
                                   the issue price and the principal amount at
                                   maturity of a LYON is referred to as original
                                   issue discount. This original issue discount
                                   accrues daily at a rate of 0.5% per year
                                   beginning on November 21, 2002, calculated on
                                   a semi-annual bond equivalent basis, using a
                                   360-day year comprised of twelve 30-day
                                   months. The accrual of imputed interest
                                   income, also referred to as tax original
                                   issue discount, as calculated for United
                                   States Federal income tax purposes, is
                                   expected to exceed the accrued original issue
                                   discount. See "Certain United States Federal
                                   Income Tax Considerations--Accrual of
                                   Interest on the LYONs."

Conversion Rights..............    For each LYON surrendered for conversion, if
                                   the conditions for conversion are satisfied,
                                   a holder will receive 4.7301 shares of our
                                   common stock. Upon conversion, we will have
                                   the right to deliver, in lieu of our common
                                   stock, cash or a combination of cash and
                                   common stock. If we elect to pay holders cash
                                   for their LYONs, the payment will be based on
                                   the average sale price of our common stock\
                                   for the five consecutive trading days
                                   immediately following either:

                                   o    the date of our notice of our election
                                        to deliver cash, which we must give
                                        within two business days after receiving
                                        a conversion notice, unless we have
                                        earlier given notice of redemption as
                                        described in this prospectus; or

                                   o    the conversion date, if we have given
                                        notice of redemption specifying that we
                                        intend to deliver cash upon conversion
                                        thereafter.`

                                   The conversion rate will be adjusted for
                                   reasons specified in the indenture but will
                                   not be adjusted for accrued original issue
                                   discount. Upon conversion, a holder will not
                                   receive any cash payment representing accrued
                                   original issue discount, contingent interest
                                   or accrued tax original issue discount.
                                   Instead, such amounts will be deemed paid by
                                   the shares of common stock, cash or a
                                   combination of cash and common stock received
                                   by the holder on conversion. See "Description
                                   of LYONs--Conversion Rights."

                                   Holders may surrender LYONs for conversion in
                                   any calendar quarter commencing after
                                   March 31, 2003 if the closing sale price of
                                   our common stock for at least 20 trading days
                                   in a period of 30 consecutive trading days
                                   ending on the last trading day of the
                                   preceding calendar quarter is more than 130%
                                   of the accreted conversion price per share of
                                   common stock on the last day of such
                                   preceding quarter. The accreted conversion
                                   price per share as of any day will equal the
                                   issue price of a LYON plus the accrued
                                   original issue discount to that day, divided
                                   by the conversion rate on that day.

                                   Holders may also surrender a LYON for
                                   conversion at any time when the credit rating
                                   assigned to the LYONs is Baa1 or lower by
                                   Moody's Investors Service ("Moody's") or BBB+
                                   or lower by Standard & Poor's Credit Market
                                   Services, a division of The McGraw-Hill
                                   Companies ("Standard & Poor's").

                                   LYONs or portions of LYONs in integral
                                   multiples of $1,000 principal amount at
                                   maturity called for redemption may also be
                                   surrendered for conversion until the close of
                                   business on the second business day prior to
                                   the redemption date. In addition, if we make
                                   certain distributions to our shareholders or
                                   if we are a party to certain consolidations,
                                   mergers or binding share exchanges, LYONs may
                                   be surrendered for conversion as provided in
                                   "Description of LYONs--Conversion Rights."
                                   The ability to surrender LYONs for conversion
                                   will expire at the close of business on
                                   November 20, 2032.

Contingent Interest............    We will pay contingent interest to the
                                   holders of LYONs during any six-month period
                                   from November 22 to May 21, and from May 22
                                   to November 21, with the initial six-month
                                   period commencing November 22, 2007, if the
                                   average market price of a LYON for the
                                   Applicable Five Trading Day Period equals
                                   130% or more of the sum of the issue price
                                   and accrued original issue discount for such
                                   LYON as of the day immediately preceding the
                                   relevant six-month period. "Applicable Five
                                   Trading Day Period" means the five trading
                                   days ending on the second trading day
                                   immediately preceding the relevant six-month
                                   period, unless we declare a regular cash
                                   dividend for which the record date falls
                                   prior to the first day of a six-month period
                                   but the payment date falls within such
                                   six-month period, in which case the
                                   "Applicable Five Trading Day Period" means
                                   the five trading days ending on the second
                                   trading day immediately preceding such record
                                   date.

                                   The amount of contingent interest payable per
                                   LYON in respect of any quarterly period
                                   within a six-month period in which contingent
                                   interest is payable will be equal to the
                                   greater of (1) any regular cash dividends
                                   paid by us per share on our common stock
                                   during that quarterly period multiplied by
                                   the then applicable conversion rate or
                                   (2) $0.62 multiplied by 4.7301.

                                   Contingent interest, if any, will accrue and
                                   be payable to holders of LYONs as of the
                                   record date for the related regular cash
                                   dividend or, if we do not pay a regular cash
                                   dividend on our common stock during a quarter
                                   within the relevant six-month period, to
                                   holders of LYONs as of the 15th day preceding
                                   the last day of the relevant six-month
                                   period. Such payments will be paid on the
                                   payment date of the related regular cash
                                   dividend or, if no regular cash dividend is
                                   paid by us during a quarter within the
                                   relevant six-month period, on the last day of
                                   the relevant six-month period. The original
                                   issue discount will continue to accrue at the
                                   yield to maturity whether or not contingent
                                   interest is paid.

Tax Original Issue Discount....    The LYONs are debt instruments subject to the
                                   United States Federal income tax contingent
                                   payment debt regulations. You should be aware
                                   that, even if we do not pay any contingent
                                   interest on the LYONs, you will be required
                                   to include interest in your gross income for
                                   United States Federal income tax purposes.
                                   This imputed interest, also referred to as
                                   tax original issue discount, will accrue at a
                                   rate equal to 4.55% per year, computed on a
                                   semi-annual bond equivalent basis, which
                                   represents the yield we believe we would have
                                   paid, as of the original issue date of the
                                   LYONs, on our noncontingent, nonconvertible,
                                   fixed-rate debt with terms otherwise similar
                                   to the LYONs, subject to a minimum yield
                                   equal to the applicable Federal rate (based
                                   on the overall maturity of the LYONs). The
                                   rate at which the tax original issue discount
                                   will accrue for United States Federal income
                                   tax purposes (which we believe will equal the
                                   minimum yield equal to the applicable Federal
                                   rate described above) will exceed the stated
                                   yield of 0.5% for the accrued original issue
                                   discount. Your adjusted tax basis in a LYON
                                   will be increased over time to reflect the
                                   accrual of the tax original issue discount
                                   and will be decreased to reflect certain
                                   projected payments on a LYON.

                                   You will also recognize gain or loss on the
                                   sale, exchange, conversion or redemption of a
                                   LYON in an amount equal to the difference
                                   between the amount realized on the sale,
                                   exchange, conversion or redemption, including
                                   the fair market value of any common stock
                                   received upon conversion or otherwise, and
                                   your adjusted tax basis in the LYON. Any gain
                                   recognized by you on the sale, exchange,
                                   conversion or redemption of a LYON generally
                                   will be ordinary interest income; any loss
                                   will be ordinary loss to the extent of the
                                   interest previously included in income, and
                                   thereafter, capital loss. See "Certain United
                                   States Federal Income Tax Considerations."

Redemption of LYONs at the
   Option of 3M ...............    We may redeem all or a portion of the LYONs
                                   for cash at any time on or after
                                   November 21, 2007 at the redemption prices
                                   set forth in "Description of
                                   LYONs--Redemption of LYONs at the Option
                                   of 3M."

                                   original issue discount to the purchase date.
                                   We may choose to pay the purchase price in
                                   cash or in common stock (based on the
                                   prevailing market price thereof) or a
                                   combination of cash and common stock. See
                                   "Description of LYONs--Purchase of LYONs by
                                   3M at the Option of the Holder."

Change in Control..............    Upon a change in control (as defined in the
                                   indenture) of 3M occurring on or before
                                   November 21, 2007, each holder may require us
                                   to repurchase all or a portion of such
                                   holder's LYONs for cash at a price equal to
                                   100% of the issue price for such LYONs plus
                                   accrued original issue discount to the date
                                   of repurchase. See "Description of
                                   LYONs--Change in Control Permits Purchase of
                                   LYONs by 3M at the Option of the Holder."

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

Trading Symbol of Our
   Common Stock................    Our common stock is traded on the New York
                                   Stock Exchange under the symbol "MMM."

RISK FACTORS

An investment in the LYONs involves a number of risks, some of which could be substantial and are inherent in our businesses. You should consider the following factors carefully before deciding to purchase LYONs. Additional risks not presently known to 3M or that 3M currently deems immaterial may also impair 3M's business operations. Actual future results and trends may differ materially from historical results or those anticipated depending on a variety of factors, including, but not limited to, those described below.

RISKS RELATED TO THIS OFFERING

AN ACTIVE TRADING MARKET FOR THE LYONS MAY NOT DEVELOP.

The LYONs comprise a new issue of securities for which there is currently no public market. The LYONs will not be listed on any securities exchange or included in any automated quotation system. We do not know whether an active trading market will develop for the LYONs. If the LYONs are traded after their initial issuance, they may trade at a discount from their initial offering price depending on prevailing interest rates, the market for similar securities, the price of our common stock, its and our performance and other factors.

IN CERTAIN CIRCUMSTANCES, YOUR CLAIMS AS A HOLDER OF A LYON COULD BE SUBORDINATED IN THE EVENT OF OUR BANKRUPTCY.

If a holder elects to convert a LYON for common stock of 3M and we thereafter become the subject of bankruptcy proceedings, if we have failed to deliver our common stock, a holder's claim in respect of the LYONs could be subordinated to all of our existing and future obligations. Furthermore, it is unclear how such a subordinated claim would be valued.

WE MAY NOT HAVE THE FUNDS NECESSARY TO PURCHASE LYONS AT THE OPTION OF THE HOLDERS OR UPON A CHANGE IN CONTROL.

On specified dates and upon the occurrence of specific kinds of change in control events occurring on or before November 21, 2007, holders of LYONs may require us to purchase all or a portion of their LYONs.

However, it is possible that upon a change in control we would not have sufficient funds to make the required purchase of LYONs or that restrictions in our other indebtedness would not allow those purchases. In addition, certain important corporate

7

events, such as leveraged recapitalizations that would increase the level of our indebtedness, would not constitute a "change in control" under the indenture. See "Description of LYONs --Change in Control Permits Purchase of LYONs by 3M at the Option of the Holder."

YOU SHOULD CONSIDER THE UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

OF OWNING LYONS.

The LYONs will be characterized as indebtedness of ours for United States federal income tax purposes. Accordingly, you will be required to include interest with respect to the LYONs in your gross income.

The LYONs constitute contingent payment debt instruments. As a result, you will be required to include amounts in income, as ordinary income, in advance of the receipt of the cash attributable thereto, and to accrue interest on a constant yield to maturity basis at a rate comparable to the rate at which we would have issued a noncontingent, nonconvertible, fixed-rate debt instrument with terms otherwise similar to the LYONs, subject to a minimum yield equal to the applicable Federal rate (based on the overall maturity of the LYONs). This rate (which will equal the required minimum rate equal to the applicable Federal rate described above) will be 4.55% per year on a semiannual compounding basis. The amount of interest income required to be included by you for each year will be in excess of the yield to maturity of the LYONs. You will recognize gain or loss on the sale, exchange, conversion or redemption of a LYON in an amount equal to the difference between the amount realized on such sale, exchange, conversion or redemption, including the fair market value of any common stock received upon conversion or otherwise, and your adjusted tax basis in the LYON. Any gain recognized by you on the sale, exchange, conversion or redemption of a LYON generally will be ordinary interest income; any loss will be ordinary loss to the extent of the interest previously included in income, and thereafter, capital loss. A summary of the United States federal income tax consequences of ownership of the LYONs is described in this prospectus under the heading "Certain United States Federal Income Tax Considerations."

RISKS RELATED TO OUR BUSINESS

3M'S BUSINESS MAY BE AFFECTED BY THE EFFECTS OF, AND CHANGES IN, WORLDWIDE ECONOMIC CONDITIONS.

3M operates in more than 60 countries and derives more than half of its revenues from sales outside the United States. 3M's business may be affected by factors in other countries that are beyond its control, such as downturns in economic activity in a specific country or region; social, political or labor conditions in a specific country or region; or potential adverse foreign tax consequences.

FOREIGN CURRENCY EXCHANGE RATES AND FLUCTUATIONS IN THOSE RATES MAY AFFECT 3M'S ABILITY TO REALIZE PROJECTED GROWTH RATES IN ITS SALES AND NET EARNINGS AND ITS RESULTS OF OPERATIONS.

Because 3M derives more than half of its revenues from sales outside the United States, 3M's ability to realize projected growth rates in its sales and net earnings and its results of operations could be adversely affected if the United States dollar strengthens significantly against foreign currencies.

3M'S GROWTH OBJECTIVES ARE LARGELY DEPENDENT ON THE TIMING AND MARKET ACCEPTANCE OF ITS NEW PRODUCT OFFERINGS.

3M's growth objectives are largely dependent on its ability to renew its pipeline of new products and to bring those products to market. This ability may be adversely affected by difficulties or delays in product development, such as the inability to:

o identify viable new products;

o successfully complete clinical trials and obtain regulatory approvals;

o obtain adequate intellectual property protection; or

o gain market acceptance of new products.

3M'S FUTURE RESULTS ARE SUBJECT TO FLUCTUATIONS IN THE COSTS OF PURCHASED COMPONENTS AND MATERIALS DUE TO MARKET DEMAND, CURRENCY EXCHANGE RISKS, SHORTAGES AND OTHER FACTORS.

3M depends on various components and materials for the manufacturing of its products. Although 3M has not experienced any difficulty in obtaining components and materials, it is possible that any of its supplier relationships could be terminated in the future. Any sustained interruption in 3M's receipt of adequate supplies could have a material adverse effect on it. In addition, while 3M has a process to minimize volatility in component and material pricing, no assurance can be given that 3M will be able to successfully manage price fluctuations due to market demand, currency risks, or shortages or that future price fluctuations will not have a material adverse effect on it.

8

3M'S ACQUISITIONS, DIVESTITURES AND STRATEGIC ALLIANCES MAY NOT BE BENEFICIAL TO
3M.

As part of 3M's strategy for growth, it has made and may continue to make acquisitions, divestitures and strategic alliances. However, there can be no assurance that any of these will be completed or beneficial to 3M.

3M IS THE SUBJECT OF VARIOUS LEGAL PROCEEDINGS.

The current estimates of the potential impact on 3M's consolidated financial position, results of operations and cash flows for its legal proceedings are predictions made by 3M about the future and should be considered forward-looking statements. These estimates could change in the future. 3M and some of its subsidiaries are named as defendants in a number of actions, governmental proceedings and claims, including environmental proceedings and products liability claims involving products now or formerly manufactured and sold by 3M.

As for products liability claims, as reported in our annual report on Form 10-K for the year ended December 31, 2001, 3M and various other companies have been named as defendants in a number of claims and lawsuits, the vast majority of which purportedly relate to the alleged use of company's mask and respirator products and seek damages from the company and other defendants for alleged personal injury from occupational exposure to asbestos or, less frequently, silica found in products manufactured by other defendants. The remaining lawsuits and claims generally allege personal injury from occupational exposure to asbestos from unspecified products claimed to have been manufactured by 3M or other defendants and/or from specialty products containing asbestos manufactured by the company and/or other defendants many years ago. In some actions, the claimants seek damages as well as other relief, which, if granted, would require substantial expenditures. 3M has accrued various liabilities, which represent reasonable estimates of its probable liabilities for these matters. 3M also has recorded receivables for the probable amount of insurance recoveries with respect to these matters.

For a more detailed discussion of legal proceedings involving 3M, see the discussion of "Legal Proceedings" in Part II, Item 1 of 3M's Quarterly Report on Form 10-Q for the period ended September 30, 2002, which is incorporated by reference into this prospectus.

RATIO OF EARNINGS TO FIXED CHARGES

The following table sets forth the ratio of earnings to fixed charges for the periods indicated:

---------------------------

(1) The ratio for the year ended December 31, 1997 includes a pre-tax gain on the sale of National Advertising Company of $803 million.
(2) The ratio for the year ended December 31, 1998 includes a pre-tax restructuring charges of $493 million.
(3) The ratio for the year ended December 31, 1999 includes a non-recurring net pre-tax gain of $100 million relating to gain on divestitures, litigation expense, an investment valuation adjustment, and a change in estimate that reduced the 1998 restructuring charges.
(4) The ratio for the year ended December 31, 2000 includes non-recurring net pre-tax losses of $23 million.
(5) The ratio for the nine months ended September 30, 2002, and year 2001, includes non-recurring net pre-tax losses of $202 million and $504 million, respectively, primarily related to the 2001 restructuring plan.

o For purposes of calculating the ratio, fixed charges consist of:

o gross interest, including the interest component of ESOP benefit expense;

o amortization of debt expense and discount or premium relating to any indebtedness; and

o the portion of rental expense on operating leases considered to be representative of the interest factor therein.

o The ratio of earnings to fixed charges is calculated as follows:

       (income from continuing operations        +     (fixed     +      (amortization of      -    (capitalized
   before income taxes and minority interest)         charges)         capitalized interest           interest)

DESCRIPTION OF LYONS

We issued the LYONs under an indenture between 3M Company and Citibank, N.A., as trustee, dated as of November 21, 2002. The following summarizes some, but not all, of the provisions of the LYONs and the indenture. The following summary does not purport to be complete and is subject to, and qualified by reference to, all of the provisions of the indenture, which we urge you to read because they define your rights as a LYONs holder. As used in this description, the words "we," "us," "3M," "3M Company," or "our" do not include any current or future subsidiary of 3M.

GENERAL

The LYONs are limited to $639,000,000 aggregate principal amount at maturity. The LYONs will mature on November 21, 2032. The principal amount at maturity of each LYON is $1,000. The LYONs are payable at the office of the paying agent, which initially will be an office or agency of the trustee, or an office or agency maintained by us for such purpose, in the Borough of Manhattan, The City of New York.

The LYONs were offered at an issue price of $860.87 per LYON, which represents a substantial discount from their principal amount at maturity. Except as described below under "--Contingent Interest", we will not make periodic payments of interest on the LYONs. However, the LYONs will accrue original issue discount while they remain outstanding. Original issue discount is the difference between the issue price and the principal amount at maturity of a LYON. Original issue discount will be calculated on a semi-annual bond equivalent basis at the yield to maturity of the LYONs, using a 360-day year comprised of twelve 30-day months. The issue date for the LYONs and the commencement date for the accrual of original issue discount were November 21, 2002.

10

The LYONs are debt instruments subject to the contingent payment debt regulations. The LYONs were issued with original issue discount for United States Federal income tax purposes. Even if we do not pay any cash interest (including any contingent interest) on the LYONs, holders will be required to include accrued tax original issue discount in their gross income for United States Federal income tax purposes. The rate at which the tax original issue discount will accrue will exceed the stated yield of 0.5% for the accrued original issue discount described above. See "Certain United States Federal Income Tax Considerations."

Maturity, conversion, purchase by us at the option of a holder or redemption of a LYON at our option will cause original issue discount and contingent interest, if any, to cease to accrue on such LYON. We may not reissue a LYON that has matured or been converted, purchased by us at your option, redeemed or otherwise cancelled, except for registration of transfer, exchange or replacement of such LYON.

LYONs may be presented for conversion at the office of the conversion agent, and for exchange or registration of transfer at the office of the registrar, each such agent initially being the trustee. We will not charge a service fee for any registration of transfer or exchange of LYONs.

RANKING OF LYONS

The LYONs are unsecured and unsubordinated obligations of ours. The LYONs rank equal in right of payment to all of our existing and future unsecured and unsubordinated indebtedness. However, a significant portion of 3M's business is conducted through subsidiaries; and, because claims by creditors of those subsidiaries would be senior to 3M's equity interests in such subsidiaries, indebtedness of 3M, including LYONs, is structurally subordinated to the claims of such creditors.

In addition, if a holder surrenders LYONs for conversion and we fail to deliver such common stock, and we then become the subject of bankruptcy proceedings, a holder's claim in respect of the LYONs could be subordinated to all of our existing and future obligations. Furthermore, it is unclear how such a subordinated claim would be valued.

As of December 31, 2002, we had approximately $3,377 million of consolidated senior indebtedness outstanding.

CONVERSION RIGHTS

Holders may surrender LYONs for conversion into shares of our common stock only if at least one of the conditions described below is satisfied. In addition, a LYON for which a holder has delivered a purchase notice or a change in control purchase notice requiring us to purchase the LYONs may be surrendered for conversion only if such notice is withdrawn in accordance with the indenture.

The initial conversion rate is 4.7301 shares of common stock per LYON, subject to adjustment upon the occurrence of certain events described below. A holder of a LYON otherwise entitled to a fractional share will receive cash equal to the applicable portion of the then current sale price of our common stock on the trading day immediately preceding the conversion date. Upon a conversion, we will have the right to deliver cash or a combination of cash and common stock, as described below.

The ability to surrender LYONs for conversion will expire at the close of business on November 20, 2032.

The conversion agent will, on our behalf, determine if the LYONs are convertible and notify the trustee and us accordingly. If one or more of the conditions to the conversion of the LYONs has been satisfied, we will promptly notify the holders of the LYONs thereof and use our reasonable best efforts to post this information on our website or otherwise publicly disclose this information.

CONVERSION BASED ON COMMON STOCK PRICE. Holders may surrender LYONs for conversion in any calendar quarter commencing after March 31, 2003, if the sale price (as defined below) of our common stock for at least 20 trading days in a period of 30 consecutive trading days ending on the last trading day of the preceding calendar quarter is more than 130% of the accreted conversion price per share of common stock on the last day of such preceding calendar quarter. The accreted conversion price per share as of any day will equal the issue price of a LYON plus the accrued original issue discount to that day, divided by the number of shares of common stock issuable upon conversion of a LYON on that day.

The table below shows the conversion trigger price per share of our common stock in respect of each of the first 20 calendar quarters following March 31, 2003. These conversion trigger prices reflect the accreted conversion price per share of common stock multiplied by 130%. Thereafter, the accreted conversion price per share of common stock increases each calendar quarter by the accreted original issue discount for the calendar quarter, and the applicable percentage remains at 130%. The conversion trigger price for the calendar quarter beginning October 1, 2032 is $274.65.

---------------------------

* This table assumes no events have occurred that would require an adjustment to the conversion rate.

CONVERSION BASED ON CREDIT RATING DOWNGRADE. Holders may also surrender a LYON for conversion during any period that the rating assigned to the LYONs by Moody's is Baa1 or lower or Standard & Poor's is BBB+ or lower.

CONVERSION BASED UPON NOTICE OF REDEMPTION. A holder may surrender for conversion a LYON called for redemption at any time prior to the close of business on the second business day immediately preceding the redemption date, even if it is not otherwise convertible at such time. A LYON for which a holder has delivered a purchase notice or a change in control purchase notice, as described below, requiring us to purchase such LYON, may be surrendered for conversion only if such notice is withdrawn in accordance with the indenture.

A "business day" is any weekday that is not a day on which banking institutions in The City of New York are authorized or obligated to close. A "trading day" is any day on which the NYSE is open for trading or, if the applicable security is quoted on the Nasdaq National Market, a day on which trades may be made on such market or, if the applicable security is not so listed, admitted for trading or quoted, any business day.

CONVERSION BASED UPON OCCURRENCE OF CERTAIN CORPORATE TRANSACTIONS. If we are party to a consolidation, merger or binding share exchange or a transfer of all or substantially all of our assets, a LYON may be surrendered for conversion at any time from and after the date which is 15 days prior to the anticipated effective date of the transaction until 15 days after the actual effective date of such transaction, and at the effective date, the right to convert a LYON into common stock will be changed into a right to convert it into the kind and amount of securities, cash or other assets of 3M or another person which the holder would have received if the holder had converted the holder's LYONs immediately prior to the transaction. If such transaction also constitutes a change in control of 3M, as defined in the indenture, the holder will be able to require us to purchase all or

12

a portion of such holder's LYONs as described under "--Change in Control Permits Purchase of LYONs by 3M at the Option of the Holder."

CONVERSION ADJUSTMENTS AND DELIVERY OF COMMON STOCK. On conversion of a LYON, a holder will not receive any cash payment representing accrued original issue discount, and accrued tax original issue discount or, except as described below, contingent cash interest. Delivery to the holder of the full number of shares of common stock into which the LYON is convertible together with any cash payment of such holder's fractional shares, or cash, or a combination of cash and common stock will be deemed:

o to satisfy our obligation to pay the principal amount at maturity of the LYON; and

o to satisfy our obligation to pay accrued original issue discount and accrued tax original issue discount, attributable to the period from the issue date through the conversion date and, except as described below, any accrued and unpaid contingent interest.

As a result, accrued original issue discount and accrued tax original issue discount are deemed paid in full rather than cancelled, extinguished or forfeited.

We and each holder of a LYON also agree that delivery to the holder of the full number of shares of common stock into which the LYON is convertible together with any cash payment of such holder's fractional shares, or cash, or a combination of cash and common stock will be treated as a payment (in an amount equal to the sum of the then fair market value of such shares and/or such cash payment, if any) on the LYON for purposes of the Treasury regulations applicable to debt instruments with contingent payments. See "Certain United States Federal Income Tax Considerations."

In lieu of delivery of shares of our common stock upon notice of conversion of any LYONs (for all or any portion of the LYONs), we may elect to pay holders surrendering LYONs an amount in cash per LYON (or a portion of a LYON) equal to the average sale price of our common stock for the five consecutive trading days immediately following either (1) the date of our notice of our election to deliver cash as described below if we have not given notice of redemption, or (2) the conversion date, in the case of conversion following our notice of redemption specifying that we intend to deliver cash upon conversion, in either case multiplied by the conversion rate in effect on that date. We will inform the holders through the trustee no later than two business days following the conversion date of our election to deliver shares of our common stock or to pay cash in lieu of delivery of the shares, unless we have already informed holders of our election in connection with our optional redemption of the LYONs as described under "--Redemption of LYONs at the Option of 3M." If we elect to deliver all of such payment in shares of our common stock, the shares will be delivered through the conversion agent no later than the fifth business day following the conversion date. If we elect to pay all or a portion of such payment in cash, the payment, including any delivery of our common stock, will be made to holders surrendering LYONs no later than the tenth business day following the applicable conversion date. If an event of default, as described under "--Events of Default" below (other than a default in a cash payment upon conversion of the LYONs), has occurred and is continuing, we may not pay cash upon conversion of any LYONs or portion of a LYON (other than cash for fractional shares).

If contingent cash interest is payable to holders of LYONs during any particular six-month period, and such LYONs are converted after the applicable record date therefor and prior to the next succeeding interest payment date, holders of such LYONs at the close of business on the record date will receive the contingent cash interest payable on such LYONs on the corresponding interest payment date notwithstanding the conversion. Such LYONs, upon surrender for conversion, must be accompanied by funds equal to the amount of contingent cash interest payable on the LYONs so converted, unless such LYONs have been called for redemption, in which case no such payment shall be required.

The conversion rate will not be adjusted for accrued original issue discount, if any, or any contingent cash interest. A certificate for the number of full shares of common stock into which any LYON is converted or cash delivered in lieu thereof, together with any cash payment for fractional shares, will be delivered through the conversion agent as soon as practicable following the conversion date. For a discussion of the tax treatment of a holder receiving shares of our common stock upon surrendering LYONs for conversion, see "Certain United States Federal Income Tax Considerations--Sale, Exchange, Conversion or Redemption."

We will adjust the conversion rate for:

o dividends or distributions on our common stock payable in our common stock or our other capital stock;

o subdivisions, combinations or certain reclassifications of our common stock;

o distributions to all holders of our common stock of certain rights to purchase our common stock for a period expiring within 60 days at less than the then current sale price; and

13

o distributions to the holders of our common stock of our assets (including shares of capital stock of a subsidiary) or debt securities or certain rights to purchase our securities (excluding cash dividends or other cash distributions from current or retained earnings, unless the amount thereof, together with all other cash dividends paid in the preceding 12 month period, per share exceeds the sum of (i) 5% of the sale price of our common stock on the day preceding the date of declaration of such dividend or other distribution and (ii) the quotient of the amount of any contingent interest paid during such period divided by the number of shares of common stock issuable upon conversion of a LYON at the conversion rate in effect on the contingent interest payment date).

In the event that we pay a dividend or make a distribution on shares of our common stock consisting of capital stock of, or similar equity interests in, a subsidiary or other business unit of ours, the conversion rate will be adjusted based on the market value of the securities so distributed relative to the market value of our common stock, in each case based on the average closing prices of those securities for the 10 trading days commencing on and including the fifth trading day after the date on which "ex-dividend trading" commences for such dividend or distribution on the NYSE or such other national or regional securities exchange or market on which the securities are then listed or quoted.

In the event we elect to make a distribution described in the third or fourth bullet of the preceding paragraph which, in the case of the fourth bullet, has a per share value equal to more than 15% of the sale price of our shares of common stock on the day preceding the declaration date for such distribution, we will be required to give notice to the holders of LYONs at least 20 days prior to the ex-dividend date for such distribution and, upon the giving of such notice, the LYONs may be surrendered for conversion at any time until the close of business on the business day prior to the ex-dividend date or until we announce that such distribution will not take place.

No adjustment to the conversion rate need be made if holders of the LYONs may participate in the transaction or in certain other cases.

If we were to implement a stockholders' rights plan providing that, upon conversion of the LYONs, the holders of such LYONs will receive, in addition to the shares of common stock issuable upon such conversion, the rights related to such common stock, there shall not be any adjustment to the conversion privilege or conversion rate as a result of:

o the issuance of the rights;

o the distribution of separate certificates representing the rights;

o the exercise or redemption of such rights in accordance with any rights agreement; or

o the termination or invalidation of the rights.

The indenture permits us to increase the conversion rate from time to time. We are not required to adjust the conversion rate until adjustments greater than 1% have occurred.

Holders of the LYONs may, in certain circumstances, be deemed to have received a distribution subject to federal income tax as a dividend upon:

o a taxable distribution to holders of common stock which results in an adjustment of the conversion rate;

o an increase in the conversion rate at our discretion; or

o failure to adjust the conversion rate in some instances.

See "Certain United States Federal Income Tax Considerations--Constructive Dividends."

CONTINGENT INTEREST

Subject to the accrual and record date provisions described below, we will pay contingent cash interest to the holders of LYONs during any six-month period from November 22 to May 21 and from May 22 to November 21, with the initial six-month period commencing November 22, 2007, if the average market price of a LYON for the Applicable Five Trading Day Period equals 130% or more of the sum of the issue price and accrued original issue discount for such LYON as of the day immediately preceding the relevant six-month period. "Applicable Five Trading Day Period" means the five trading days ending on the second trading day immediately preceding the first day of the relevant six-month period, unless we declare a regular cash dividend for which the record date falls prior to the first day of a six-month period but the payment date falls within such six-month period, in

14

which case the "Applicable Five Trading Day Period" means the five trading days ending on the second trading day immediately preceding such record date.

The amount of contingent interest payable per LYON in respect of any quarterly period within a six-month period in which contingent interest is payable will equal the greater of (1) any regular cash dividends paid by us per share on our common stock during that quarterly period multiplied by the then applicable conversion rate or (2) $0.62 multiplied by 4.7301.

Contingent interest, if any, will accrue and be payable to holders of LYONs as of the record date for the related common stock dividend or, if we do not pay a regular cash dividend on our common stock during the relevant six- month period, to holders of LYONs as of the 15th day preceding the last day of the relevant six-month period. We will make contingent interest payments on the payment date of the related common stock dividend or, if we do not pay a regular cash dividend on our common stock during the relevant six-month period, on the last day of the relevant six-month period. The original issue discount will continue to accrue at the yield to maturity whether or not contingent interest is paid.

Regular cash dividends are quarterly or other periodic cash dividends on our common stock as declared by our Board of Directors as part of its cash dividend payment practices and that are not designated by them as extraordinary or special or other nonrecurring dividends.

The market price of a LYON on any date of determination means the average of the secondary market bid quotations per LYON obtained by the bid solicitation agent for $10 million principal amount at maturity of LYONs at approximately 4:00 p.m., New York City time, on such determination date from three independent nationally recognized securities dealers we select, provided that if:

o at least three such bids are not obtained by the bid solicitation agent; or

o in our reasonable judgment, the bid quotations are not indicative of the secondary market value of the LYONs, then the market price of the LYON will equal (1) the then applicable conversion rate of the LYONs multiplied by (2) the average sale price of our common stock on the five trading days ending on such determination date, appropriately adjusted.

The bid solicitation agent is Citibank, N.A. We may change the bid solicitation agent, but the bid solicitation agent will not be our affiliate. The bid solicitation agent will solicit bids from securities dealers that are believed by us to be willing to bid for the LYONs.

Upon determination that LYON holders will be entitled to receive contingent interest during a relevant six-month period, on or prior to the start of such six-month period, we will issue a press release and publish such information on our website as soon as practicable.

PURCHASE OF LYONS BY 3M AT THE OPTION OF THE HOLDER

On the purchase dates of November 21, 2005, November 21, 2007, November 21, 2012, November 21, 2017, November 21, 2022, and November 21, 2027, holders may require us to purchase any outstanding LYON for which the holder has properly delivered and not withdrawn a written purchase notice, subject to certain additional conditions. We may, in our sole discretion, provide the holders with additional rights to require us to purchase the LYONs on additional purchase dates. We will notify the holders if we elect to provide any such additional rights. Holders may submit their LYONs for purchase to the paying agent at any time from the opening of business on the date that is 20 business days prior to the purchase date until the close of business on the business day immediately preceding the purchase date.

The purchase price of a LYON will be:

o $873.86 per LYON on November 21, 2005;

o $882.64 per LYON on November 21, 2007;

o $904.95 per LYON on November 21, 2012;

o $927.83 per LYON on November 21, 2017;

o $951.29 per LYON on November 21, 2022; and

o $975.34 per LYON on November 21, 2027.

15

The purchase prices shown above are equal to the issue price plus accrued original discount to the purchase date. We may, at our option, elect to pay the purchase price in cash, shares of common stock, or any combination thereof. For a discussion of the tax treatment of a holder receiving cash, shares of common stock or any combination thereof, see "Certain United States Federal Income Tax Considerations--Sale, Exchange, Conversion or Redemption."

We will be required to give notice on a date not less than 20 business days prior to each purchase date to all holders at their addresses shown in the register of the registrar, and to beneficial owners as required by applicable law, stating among other things:

o whether we will pay the purchase price of LYONs in cash or common stock or any combination thereof, specifying the percentages of each;

o if we elect to pay in common stock, the method of calculating the market price of the common stock; and

o the procedures that holders must follow to require us to purchase their LYONs.

The purchase notice given by each holder electing to require us to purchase LYONs shall be given to the paying agent no later than the close of business on the business day immediately preceding the purchase date and must state:

o the certificate numbers of the holder's LYONs to be delivered for purchase;

o the portion of the principal amount at maturity of LYONs to be purchased, which must be $1,000 or an integral multiple of $1,000;

o that the LYONs are to be purchased by us pursuant to the applicable provisions of the LYONs; and

o in the event we elect, pursuant to the notice that we are required to give, to pay the purchase price in common stock, in whole or in part, but the purchase price is ultimately to be paid to the holder entirely in cash because any of the conditions to payment of the purchase price or portion of the purchase price in common stock is not satisfied prior to the close of business on the purchase date, as described below, whether the holder elects:

(1) to withdraw the purchase notice as to some or all of the LYONs to which it relates, or

(2) to receive cash in such event in respect of the entire purchase price for all LYONs or portions of LYONs subject to such purchase notice.

If the holder fails to indicate the holder's choice with respect to the election described in the final bullet point above, the holder shall be deemed to have elected to receive cash in respect of the entire purchase price for all LYONs subject to the purchase notice in these circumstances.

A holder may withdraw any purchase notice by delivering a written notice of withdrawal to the paying agent prior to the close of business on the purchase date.

The notice of withdrawal shall state:

o the principal amount at maturity of the LYONs being withdrawn;

o the certificate numbers of the LYONs being withdrawn; and

o the principal amount at maturity, if any, of the LYONs that remain subject to the purchase notice.

If we elect to pay the purchase price, in whole or in part, in shares of our common stock, the number of shares of our common stock to be delivered by us shall be equal to the portion of the purchase price to be paid in common stock divided by the market price of one share of common stock. We will pay cash based on the market price for all fractional shares of our common stock in the event we elect to deliver our common stock in payment, in whole or in part, of the purchase price.

We will pay cash based on the market price for all fractional shares of common stock in the event we elect to deliver common stock in payment, in whole or in part, of the purchase price. See "Certain United States Federal Income Tax Considerations--Sale, Exchange, Conversion or Redemption."

The "market price" means the average of the sale prices of our common stock for the five trading day period ending on the third business day prior to the applicable purchase date. If the third business day prior to the applicable purchase date is not a

16

trading day, the five trading day period shall end on the last trading day prior to such third business day. We will appropriately adjust the market price to take into account the occurrence, during the period commencing on the first of such trading days during such five trading day period and ending on such purchase date, of certain events that would result in an adjustment of the conversion rate with respect to the common stock.

The "sale price" of our common stock on any date means the closing per share sale price (or if no closing sale price is reported, the average of the bid and ask prices or, if more than one in either case, the average of the average bid and the average ask prices) on such date on the New York Stock Exchange or such other principal United States securities exchange on which the common stock is traded or, if the common stock is not listed on a United States national or regional securities exchange, as reported by the National Association of Securities Dealers Automated Quotation System or by the National Quotation Bureau Incorporated. In the absence of a quotation, we will determine the sale price on the basis of such quotations as we consider appropriate.

Because the market price of our common stock is determined prior to the applicable purchase date, holders of LYONs bear the market risk with respect to the value of the common stock to be received from the date such market price is determined to such purchase date. We may pay the purchase price or any portion of the purchase price in common stock only if the information necessary to calculate the market price is published in a daily newspaper of national circulation or by other appropriate means.

Upon determination of the actual number of shares of common stock to be issued for each $1,000 principal amount at maturity of LYONs in accordance with the foregoing provisions, we promptly will issue a press release and publish such information on our website.

In addition to the above conditions, our right to purchase LYONs, in whole or in part, with common stock is subject to our satisfying various conditions, including:

o listing such common stock on the principal United States securities exchange on which our common stock is then listed;

o the registration of the common stock under the Securities Act and the Exchange Act, if required; and

o any necessary qualification or registration under applicable state securities law or the availability of an exemption from such qualification and registration.

If such conditions are not satisfied with respect to a holder prior to the close of business on the purchase date, we will pay the purchase price of the LYONs of the holder entirely in cash. We may not change the form or components or percentages of components of consideration to be paid for the LYONs once we have given the notice that we are required to give to holders of the LYONs, except as described in the first sentence of this paragraph.

In connection with any purchase offer, we will to the extent applicable:

o comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act which may then be applicable;

o file Schedule TO or any other required schedule under the Exchange Act; and

o otherwise comply with all federal and state securities laws as necessary under the indenture to effect a purchase of LYONs by us at the option of a holder.

Our obligation to pay the purchase price of a LYON for which a purchase notice has been delivered and not validly withdrawn is conditioned upon the holder delivering the LYON, together with necessary endorsements, to the paying agent at any time after delivery of the purchase notice. We will cause the purchase price plus accrued and unpaid contingent interest, if any, of the LYON to be paid promptly following the later of the purchase date or the time of delivery of the LYON.

If the paying agent holds money or securities sufficient to pay the purchase price of the LYON on the business day following the purchase date in accordance with the terms of the indenture, then, immediately after the purchase date, the LYON will cease to be outstanding and original issue discount on such LYON will cease to accrue, whether or not the LYON is delivered to the paying agent. Thereafter, all other rights of the holder shall terminate, other than the right to receive the purchase price upon delivery of the LYON.

Our ability to purchase LYONs with cash may be limited by the terms of our then existing borrowing agreements, as well as the amount of funds available to us to fund any such purchases.

17

We may not purchase any LYONs for cash at the option of holders if an event of default with respect to the LYONs has occurred and is continuing, other than a default in the payment of the purchase price with respect to such LYONs.

REDEMPTION OF LYONS AT THE OPTION OF 3M

No sinking fund is provided for the LYONs. Prior to November 21, 2007, we will not have the option to redeem the LYONs. Beginning on November 21, 2007, we may redeem the LYONs for cash as a whole at any time, or in part from time to time. We will give not less than 30 days nor more than 60 days notice of redemption by mail to holders of LYONs. LYONs or portions of LYONs called for redemption will be convertible by the holder until the close of business on the second business day prior to the redemption date.

The table below shows the redemption prices of a LYON on November 21, 2007, at each November 21 thereafter prior to maturity and at stated maturity on November 21, 2032. These prices reflect the issue price plus accrued original issue discount to the redemption date. The redemption price of a LYON redeemed between such dates would include an additional amount reflecting the additional original issue discount accrued since the next preceding date in the table and until, but not including, the redemption date.

If a redemption date occurs during a period when contingent interest is payable with respect to the LYONs, accrued and unpaid contingent interest to but excluding the date of redemption will be paid in addition to the redemption price.

If we redeem less than all of the outstanding LYONs, the trustee will select the LYONs to be redeemed on a pro rata basis in principal amounts at maturity of $1,000 or integral multiples of $1,000 by lot, pro rata, based on the ownership thereof, or by any other method the trustee considers fair and appropriate. If a portion of a holder's LYONs is selected for partial redemption and the holder converts a portion of the LYONs, the converted portion will be deemed to be the portion selected for redemption.

CHANGE IN CONTROL PERMITS PURCHASE OF LYONS BY 3M AT THE OPTION OF THE HOLDER

In the event of a change in control, as defined below, occurring on or prior to November 21, 2007 with respect to 3M, each holder will have the right, at its option, subject to the terms and conditions of the indenture, to require us to purchase for cash all or any portion of the holder's LYONs in integral multiples of $1,000 principal amount at maturity, at a price for each $1,000 principal amount at maturity of such LYONs equal to the issue price plus accrued original issue discount to the purchase date.

We are required to purchase the LYONs no later than 35 business days after the occurrence of such change in control (a "change in control purchase date") at a cash price equal to the issue price plus accrued original issue discount to the change of control purchase date.

Within 15 business days after the occurrence of a change in control, we must mail to the trustee and to all holders of LYONs at their addresses shown in the register of the registrar and to beneficial owners as required by applicable law a notice regarding the change in control, which notice shall state, among other things:

o the events causing a change in control;

o the date of such change in control;

o the last date on which a holder may exercise the purchase right;

o the change in control purchase price;

o the change in control purchase date;

o the name and address of the paying agent and the conversion agent;

o the conversion rate and any adjustments to the conversion rate;

o that LYONs with respect to which a change in control purchase notice is given by the holder may be converted, if otherwise convertible, only if the change in control purchase notice has been withdrawn in accordance with the terms of the indenture; and

o the procedures that holders must follow to exercise these rights.

To exercise this right, the holder must deliver a written notice to the paying agent no later than the close of business on the change in control purchase date. The required purchase notice upon a change in control must state:

o the certificate numbers of the LYONs to be delivered by the holder;

o the portion of the principal amount at maturity of LYONs to be purchased, which portion must be $1,000 or an integral multiple of $1,000; and

o that we are to purchase the LYONs pursuant to the applicable provisions of the LYONs.

A holder may withdraw any change in control purchase notice by delivering to the paying agent a written notice of withdrawal prior to the close of business on the change in control purchase date. The notice of withdrawal must state:

o the principal amount at maturity of the LYONs being withdrawn;

o the certificate numbers of the LYONs being withdrawn; and

o the principal amount at maturity, if any, of the LYONs that remain subject to a change in control purchase notice.

Our obligation to pay the change in control purchase price for a LYON for which a change in control purchase notice has been delivered and not validly withdrawn is conditioned upon delivery of the LYON, together with necessary endorsements, to the paying agent at any time after the delivery of such change in control purchase notice. We will cause the change in control purchase price for such LYON to be paid promptly following the later of the change in control purchase date or the time of delivery of such LYON.

If the paying agent holds money sufficient to pay the change in control purchase price of the LYON on the change in control purchase date in accordance with the terms of the indenture, then, immediately after the change in control purchase date,

19

original issue discount on such LYON will cease to accrue, whether or not the LYON is delivered to the paying agent. Thereafter, all other rights of the holder shall terminate, other than the right to receive the change in control purchase price upon delivery of the LYON.

Under the indenture, a "change in control" of 3M is deemed to have occurred at such time as:

o any person, including its respective affiliates and associates, other than 3M, its subsidiaries or their employee benefit plans, files a Schedule 13D or Schedule TO (or any successor schedule, form or report under the Exchange Act) disclosing that such person has become the beneficial owner of 50% or more of the aggregate voting power of our common stock and other capital stock with equivalent voting rights, or other capital stock into which the common stock is reclassified or changed, with certain exceptions; or

o there shall be consummated any share exchange, consolidation or merger of 3M pursuant to which the common stock would be converted into cash, securities or other property in which the holders of our common stock and other capital stock with equivalent voting rights immediately prior to the share exchange, consolidation or merger, have, directly or indirectly, less than a majority of the total voting power in the aggregate of all classes of capital stock of the continuing or surviving corporation immediately after the share exchange, consolidation or merger.

For purposes of defining a change in control:

o the term "person" and the term "group" have the meanings given by Section 13(d) and 14(d) of the Exchange Act or any successor provisions;

o the term "group" includes 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 or any successor provision; and

o the term "beneficial owner" is determined in accordance with Rules 13d-3 and 13d-5 under the Exchange Act or any successor provisions, except that a person will be deemed to have beneficial ownership of all shares that person has the right to acquire irrespective of whether that right is exercisable immediately or only after the passage of time.

The indenture does not permit our board of directors to waive our obligation to purchase LYONs at the option of holders in the event of a change in control.

In connection with any purchase offer in the event of a change in control, we will to the extent applicable:

o comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act which may then be applicable;

o file Schedule TO or any other required schedule under the Exchange Act; and

o otherwise comply with all federal and state securities laws as necessary under the indenture to effect a change in control purchase of LYONs by us at the option of a holder.

The change in control purchase feature of the LYONs may in certain circumstances make more difficult or discourage a takeover of 3M. The change in control purchase feature, however, is not the result of our knowledge of any specific effort:

o to accumulate shares of our common stock;

o to obtain control of 3M by means of a merger, tender offer, solicitation or otherwise; or

o part of a plan by management to adopt a series of anti-takeover provisions.

Instead, the change in control purchase feature is a standard term contained in other LYONs offerings that have been marketed by Merrill Lynch. The terms of the change in control purchase feature resulted from negotiations between Merrill Lynch and us.

We could, in the future, enter into certain transactions, including certain recapitalizations, that would not constitute a change in control with respect to the change in control purchase feature of the LYONs but that would increase the amount of our (or our subsidiaries') outstanding indebtedness.

20

We may not purchase LYONs at the option of holders upon a change in control if there has occurred and is continuing an event of default with respect to the LYONs, other than a default in the payment of the change in control purchase price with respect to the LYONs.

MERGER AND SALES OF ASSETS BY 3M

The indenture provides that we may consolidate with or merge into any other person or convey, transfer or lease our properties and assets substantially as an entirety to another person, provided that:

o the resulting, surviving or transferee person (if other than
3M) is organized and existing under the laws of the United States, any state thereof or the District of Columbia;

o such person assumes all obligations of 3M under the LYONs and the indenture; and

o 3M or such successor person is not immediately thereafter in default under the indenture.

Upon the assumption of the obligations of 3M by such a person in such circumstances, subject to certain exceptions, 3M will be discharged from all obligations under the LYONs and the indenture. Although such transactions are permitted under the indenture, certain of the foregoing transactions occurring on or prior to November 21, 2007 could constitute a change in control of 3M permitting each holder to require 3M or such successor person to purchase the LYONs of such holder as described above.

EVENTS OF DEFAULT

The following are events of default for the LYONs:

(1) default in payment of the principal amount at maturity, redemption price, purchase price or change in control purchase price with respect to any LYONs when such becomes due and payable;

(2) default in payment of any contingent interest, which default continues for 30 days;

(3) our failure to comply with any of our other agreements in the LYONs or the indenture upon our receipt of notice of such default from the trustee or from holders of not less than 25% in aggregate principal amount at maturity of the LYONs then outstanding, and our failure to cure (or obtain a waiver of) such default within 90 days after we receive such notice;

(4) default under any indebtedness for borrowed money, including other series of debt securities, or under any mortgage, lien or other similar encumbrance, indenture or instrument ("Indebtedness"), including the indenture, which secures any Indebtedness for borrowed money, and which results in acceleration of the maturity of an outstanding principal amount of Indebtedness greater than $20 million, unless this acceleration is rescinded (or the Indebtedness is discharged) within 10 days after we have received written notice of the default in the manner specified in the indenture; or

(5) certain events of bankruptcy or insolvency affecting us or any of our "significant subsidiaries" (as such term is defined under Regulation S-X under the Securities Act).

If an event of default shall have happened and be continuing, either the trustee or the holders of not less than 25% in aggregate principal amount at maturity of the LYONs then outstanding may declare the issue price of the LYONs plus the original issue discount on the LYONs accrued through the date of such declaration, and any accrued and unpaid contingent interest through the date of such declaration, to be immediately due and payable. In the case of certain events of bankruptcy or insolvency, the issue price of the LYONs plus the original issue discount and any unpaid contingent interest accrued thereon through the occurrence of such event shall automatically become and be immediately due and payable.

BOOK-ENTRY SYSTEM

The LYONs are issued only in the form of global securities held in book-entry form. DTC or its nominee is the sole registered holder of the LYONs for all purposes under the indenture. Owners of beneficial interests in the LYONs represented by the global securities hold their interests pursuant to the procedures and practices of DTC. As a result, beneficial interests in any such securities are shown on, and transfers are effected only through, records maintained by DTC and its direct and indirect participants and any such interest may not be converted for certificated securities, except in limited circumstances. Owners of beneficial interests must exercise any rights in respect of their interests, including any right to convert or require purchase of their interests in the LYONs, in accordance with the procedures and practices of DTC. Beneficial owners are not holders and will not

21

be entitled to any rights provided to the holders of LYONs under the global securities or the indenture. 3M and the trustee, and any of their respective agents, may treat DTC as the sole holder and registered owner of the global securities.

ISSUANCE OF CERTIFICATED SECURITIES FOR GLOBAL SECURITIES

LYONs represented by one or more global securities are exchangeable for LYONs represented by certificated securities in registered form with the same terms only if:

o DTC is unwilling or unable to continue as depositary or if DTC ceases to be a clearing agency registered under the Exchange Act and a successor depositary is not appointed by us within 90 days;

o we decide to discontinue use of the system of book-entry transfer through DTC (or any successor depositary); or

o a default under the indenture occurs and is continuing.

DTC has advised us as follows: DTC is a limited-purpose trust company organized under the New York Banking Law, a "banking organization" within the meaning of the New York Uniform Commercial Code, and a "clearing agency" registered pursuant to the provisions of Section 17A of the Exchange Act. DTC facilitates the settlement of transactions among its participants through electronic computerized book-entry changes in participants' accounts, eliminating the need for physical movement of securities certificates. DTC participants include securities brokers and dealers, including Merrill Lynch, banks, trust companies, clearing corporations and other organizations, some of whom and/or their representatives own DTC. Access to DTC's book-entry system is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly.

MODIFICATION

We and the trustee may enter into supplemental indentures that add, change or eliminate provisions of the indenture or modify the rights of the holders of the LYONs with the consent of the holders of at least a majority in principal amount at maturity of the LYONs then outstanding. However, without the consent of each holder affected thereby, no supplemental indenture may:

o alter the manner of calculation or rate of accrual of original issue discount or contingent interest on any LYON or extend the time of payment;

o make any LYON payable in money or securities other than that stated in the LYON;

o change the stated maturity of any LYON;

o reduce the principal amount at maturity, issue price, redemption price, purchase price or change in control purchase price with respect to any LYON;

o make any change that adversely affects the right of a holder to convert any LYON;

o make any change that adversely affects the right to require us to purchase a LYON;

o impair the right to receive payment with respect to the LYONs or the right to institute suit for the enforcement of any payment with respect to, or conversion of, the LYONs; or

o change the provisions in the indenture that relate to modifying or amending the indenture.

Without the consent of any holder of LYONs, we and the trustee may enter into supplemental indentures for any of the following purposes:

o to evidence a successor to us and the assumption by that successor of our obligations under the indenture and the LYONs;

o to add to our covenants for the benefit of the holders of the LYONs or to surrender any right or power conferred upon us;

o to secure our obligations in respect of the LYONs and the indenture;

22

o to make any changes or modifications to the indenture necessary in connection with the registration of the LYONs under the Securities Act and the qualification of the LYONs under the Trust Indenture Act as contemplated by the indenture;

o to cure any ambiguity, omission, defect or inconsistency in the indenture; and

o to provide the holders with additional rights to require us to purchase the LYONs on additional purchase dates.

The holders of a majority in principal amount at maturity of the outstanding LYONs may, on behalf of the holders of all LYONs, (i) waive compliance by us with restrictive provisions of the indenture, as detailed in the indenture and (ii) waive any past default under the indenture and its consequences, except a default in the payment of the principal amount at maturity, issue price, accrued and unpaid contingent interest, accrued original issue discount, redemption price, purchase price or change in control purchase price or obligation to deliver shares of common stock upon conversion with respect to any LYON or in respect of any provision which under the indenture cannot be modified or amended without the consent of the holder of each outstanding LYON affected.

DISCHARGE OF THE INDENTURE

We may satisfy and discharge our obligations under the indenture by delivering to the trustee for cancellation all outstanding LYONs or by depositing with the trustee, the paying agent or the conversion agent, if applicable after the LYONs have become due and payable, whether at stated maturity, or any redemption date, any purchase date, or a change in control purchase date, or upon conversion or otherwise, cash or shares of our common stock or government obligations (as applicable under the terms of the indenture) sufficient to pay all of the outstanding LYONs and paying all other sums payable under the indenture by us.

LIMITATIONS OF CLAIMS IN BANKRUPTCY

If a bankruptcy proceeding is commenced in respect of 3M, the claim of the holder of a LYON is, under Title 11 of the United States Code, limited to the issue price of the LYON plus that portion of the original issue discount that has accrued from the date of issue to the commencement of the proceeding, plus accrued and unpaid contingent interest, if any.

INFORMATION CONCERNING THE TRUSTEE

Citibank, N.A. is the trustee, registrar, paying agent and conversion agent under the indenture. We may maintain deposit accounts and conduct other banking transactions with the trustee in the normal course of business.

GOVERNING LAW

The indenture and the LYONs are governed by, and construed in accordance with, the law of the State of New York.

DESCRIPTION OF OUR CAPITAL STOCK

GENERAL

The following description of our capital stock is subject to and qualified in its entirety by our certificate of incorporation and bylaws, which have been publicly filed with the SEC, and by the provisions of applicable Delaware law. See "Where You Can Find More Information."

Our authorized capital stock consists of:

o 1,500,000,000 shares of common stock, $0.01 par value; and

o 10,000,000 shares of preferred stock, no par value.

Each holder of our common stock is entitled to one vote per share on all matters to be voted upon by the stockholders. Subject to preferences that may be applicable to any outstanding preferred stock, the holders of our common stock are entitled to receive ratably such dividends, if any, as may be declared from time to time by the board of directors out of funds legally available for that purpose. In the event of our liquidation, dissolution or winding up, the holders of our common stock are entitled to share ratably in all assets remaining after payment of liabilities, subject to prior distribution rights of preferred stock, if any, then outstanding. The holders of our common stock have no preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund provisions applicable to the common stock.

23

PREFERRED STOCK

The board of directors has the authority, without action by the stockholders, to designate and issue preferred stock in one or more series and to designate the rights, preferences and privileges of each series, which may be greater than the rights of the common stock. It is not possible to state the actual effect of the issuance of any shares of preferred stock upon the rights of holders of the common stock until the board of directors determines the specific rights of the holders of such preferred stock. However, the effects might include, among other things:

o restricting dividends on the common stock;

o diluting the voting power of the common stock;

o impairing the liquidation rights of the common stock; or

o delaying or preventing a change in control of us without further action by the stockholders.

Certain other provisions of our certificate of incorporation and bylaws could also delay or prevent a change in control. These include a provision of our certificate of incorporation that requires, absent prior board approval, the approval of any merger, sale or certain other business combinations by holders of at least 80% of our outstanding common stock.

No shares of preferred stock are outstanding, and we have no present plans to issue any shares of preferred stock.

TRANSFER AGENT AND REGISTRAR

The transfer agent and registrar for our common stock is Wells Fargo Bank N.A. Shareowner Services.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

GENERAL

This is a summary of certain United States federal income tax consequences relevant to holders of LYONs. This summary is based upon laws, regulations, rulings and decisions now in effect, all of which are subject to change (including retroactive changes) or possible differing interpretations. The discussion below deals only with LYONs held as capital and does not purport to deal with persons in special tax situations, such as financial institutions, insurance companies, regulated investment companies, dealers in securities or currencies, tax-exempt entities, persons holding LYONs in a tax-deferred or tax-advantaged account, or persons holding LYONs as a hedge against currency risks, as a position in a "straddle" or as part of a "hedging" or "conversion" transaction for tax purposes.

We do not address all of the tax consequences that may be relevant to an investor in LYONs. In particular, we do not address:

o the United States federal income tax consequences to shareholders in, or partners or beneficiaries of, an entity that is a holder of LYONs;

o the United States federal estate, gift or alternative minimum tax consequences of the purchase, ownership or disposition of LYONs;

o U.S. holders (as defined below) whose functional currency is not the United States dollar;

o any state, local or foreign tax consequences of the purchase, ownership or disposition of LYONs; or

o any United States federal, state, local or foreign tax consequences of owning or disposing of 3M common stock.

Persons considering the purchase of the LYONs should consult their own tax advisors concerning the application of the United States federal income tax laws to their particular situations as well as any consequences of the purchase, ownership and disposition of the LYONs arising under the laws of any other taxing jurisdiction.

A U.S. holder is a beneficial owner of the LYONs who or which is:

o a citizen or individual resident of the United States, as defined in section 7701(b) of the Internal Revenue Code of 1986, as amended (which we refer to as the Code);

24

o a corporation or partnership, including any entity treated as a corporation or partnership for United States federal income tax purposes, created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

o an estate if its income is subject to United States federal income taxation regardless of its source; or

o a trust if (1) a United States court can exercise primary supervision over its administration, and (2) one or more United States persons have the authority to control all of its substantial decisions.

Notwithstanding the preceding sentence, certain trusts in existence on August 20, 1996, and treated as U.S. persons prior to such date, may also be treated as U.S. holders. A Non-U.S. holder is a beneficial owner of LYONs other than a U.S. holder.

WE URGE PROSPECTIVE INVESTORS TO CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE LYONS AND 3M COMMON STOCK IN LIGHT OF THEIR OWN PARTICULAR CIRCUMSTANCES, INCLUDING THE TAX CONSEQUENCES UNDER STATE, LOCAL, FOREIGN AND OTHER TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN UNITED STATES FEDERAL OR OTHER TAX LAWS.

CLASSIFICATION OF THE LYONS

We have received an opinion from our Tax Counsel, Henry W. Gjersdal, Jr., that the LYONs will be treated as indebtedness for United States federal income tax purposes and that the LYONs will be subject to the special regulations governing contingent payment debt instruments (which we refer to as the "CPDI" regulations). Pursuant to the terms of the indenture, we and each holder of the LYONs agree, for United States federal income tax purposes, to treat the LYONs as debt instruments that are subject to the CPDI regulations. In addition, under the indenture, each holder will be deemed to have agreed to treat the fair market value of our common stock received by such holder upon conversion as a contingent payment and to accrue interest with respect to the LYONs as original issue discount for United States federal income tax purposes according to the "noncontingent bond method," set forth in section 1.1275-4(b) of the Treasury Regulations, using the comparable yield (as defined below) compounded semiannually and the projected payment schedule (as defined below) determined by us.

Recently, the Internal Revenue Service (which we refer to as the "IRS") issued Revenue Ruling 2002-31 and Notice 2002-36 addressing the United States federal income tax classification and treatment of instruments substantially similar to the LYONs, and concluded that the instruments addressed in that published guidance were subject to the CPDI regulations. In addition, the IRS clarified various aspects of the potential applicability of certain other provisions of the Code to instruments addressed in that published guidance. However, Revenue Ruling 2002-31 is limited to its particular facts. In addition, no rulings have been sought or are expected to be sought from the IRS with respect to any of the United States federal income tax consequences discussed below. As a result, no assurance can be given that the IRS or a court will agree with the tax characterizations and the tax treatment described below. The remainder of this discussion assumes that the LYONs are subject to the CPDI regulations. Any differing treatment could affect the amount, timing and character of income, gain or loss in respect of an investment in the LYONs. In particular, a holder might be required to accrue interest income at a higher or lower rate, might not recognize income, gain or loss upon conversion of the LYONs into common stock, and might recognize capital gain or loss upon a taxable disposition of the LYONs. Holders should consult their tax advisors concerning the tax treatment of holding the LYONs.

ACCRUAL OF INTEREST ON THE LYONS

Pursuant to the CPDI regulations, a U.S. holder will be required to accrue interest income on the LYONs, in the amounts described below, regardless of whether the U.S. holder uses the cash or accrual method of tax accounting. Accordingly, U.S. holders will be required to include interest in taxable income in each year in excess of the accruals on the LYONs for non-tax purposes and in excess of any contingent interest payments actually received in that year.

The CPDI regulations provide that a U.S. holder must accrue an amount of ordinary interest income, as original issue discount for United States federal income tax purposes, for each accrual period prior to and including the maturity date of the LYONs that equals:

(1) the product of (i) the adjusted issue price (as defined below) of the LYONs as of the beginning of the accrual period, and (ii) the comparable yield to maturity (as defined below) of the LYONs, adjusted for the length of the accrual period;

(2) divided by the number of days in the accrual period; and

25

(3) multiplied by the number of days during the accrual period that the U.S. holder held the LYONs.

A LYON's issue price is the first price at which a substantial amount of the LYONs is sold to the public, excluding sales to bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers. The adjusted issue price of a LYON is its issue price increased by any interest income previously accrued, determined without regard to any adjustments to interest accruals described below, and decreased by the amount of any projected payments, as defined below, previously made on the LYONs.

Henry W. Gjersdal, Jr., our Tax Counsel, has advised us that the term "comparable yield" means the annual yield we would pay, as of the initial issue date, on a noncontingent, nonconvertible, fixed-rate debt security with terms and conditions otherwise comparable to those of the LYONs. Moreover, Henry W. Gjersdal, Jr., our Tax Counsel, has advised us that the comparable yield must be a reasonable yield for us and must not be less than the applicable Federal rate (based on the overall maturity of the LYONs). Based in part on that advice, we intend to take the position that the comparable yield for the LYONs is 4.55%, compounded semiannually (which equals the required minimum yield equal to the applicable Federal rate described above). The precise manner of calculating the comparable yield is not entirely clear. If the comparable yield were successfully challenged by the IRS, the redetermined yield could be materially greater or less than the comparable yield provided by us. Moreover, in such event, the projected payment schedule could differ materially from the projected payment schedule provided by us.

The CPDI regulations require that we provide to U.S. holders, solely for United States federal income tax purposes, a schedule of the projected amounts of payments, which we refer to as projected payments, on the LYONs. This schedule must produce the comparable yield. The projected payment schedule includes estimates for certain contingent interest payments and an estimate for a payment at maturity taking into account the conversion feature. In this connection, the fair market value of any common stock (and cash, if any) received by a holder upon conversion will be treated as a contingent payment.

The comparable yield and the schedule of projected payments will be set forth in the indenture. U.S. holders may also obtain the projected payment schedule by submitting a written request for such information to: 3M Company, 3M Center. St. Paul, Minnesota 55144, Attention: Corporate Secretary.

For United States federal income tax purposes, a U.S. holder must use the comparable yield and the schedule of projected payments in determining its interest accruals, and the adjustments thereto described below, in respect of the LYONs, unless such U.S. holder timely discloses and justifies the use of other estimates to the IRS. A U.S. holder that determines its own comparable yield or schedule of projected payments must also establish that our comparable yield or schedule of projected payments is unreasonable.

THE COMPARABLE YIELD AND THE SCHEDULE OF PROJECTED PAYMENTS ARE NOT DETERMINED FOR ANY PURPOSE OTHER THAN FOR THE DETERMINATION OF A U.S. HOLDER'S INTEREST ACCRUALS AND ADJUSTMENTS THEREOF IN RESPECT OF THE LYONS FOR UNITED STATES FEDERAL INCOME TAX PURPOSES AND DO NOT CONSTITUTE A PROJECTION OR REPRESENTATION REGARDING THE ACTUAL AMOUNTS PAYABLE ON THE LYONS.

Amounts treated as interest under the CPDI regulations are treated as original issue discount for all purposes of the Code.

ADJUSTMENTS TO INTEREST ACCRUALS ON THE LYONS

If, during any taxable year, a U.S. holder receives actual payments with respect to the LYONs for that taxable year that in the aggregate exceed the total amount of projected payments for that taxable year, the U.S. holder will incur a "net positive adjustment" under the CPDI regulations equal to the amount of such excess. The U.S. holder will treat a "net positive adjustment" as additional interest income for the taxable year. For this purpose, the payments in a taxable year include the fair market value of property received in that year, including the fair market value of our common stock received upon conversion or redemption.

If a U.S. holder receives in a taxable year actual payments with respect to the LYONs for that taxable year that in the aggregate are less than the amount of projected payments for that taxable year, the U.S. holder will incur a "net negative adjustment" under the CPDI regulations equal to the amount of such deficit. This adjustment will (a) first reduce the U.S. holder's interest income on the LYONs for that taxable year, and (b) to the extent of any excess after the application of (a), give rise to an ordinary loss to the extent of the U.S. holder's interest income on the LYONs during prior taxable years, reduced to the extent such interest was offset by prior net negative adjustments. A negative adjustment is not subject to the two percent floor limitation imposed on miscellaneous itemized deductions under section 67 of the Code. Any negative adjustment in excess of the amounts described in (a) or (b) will be carried forward to offset future interest income accruals in respect of the LYONs or to reduce the amount realized on the sale, exchange, conversion or retirement of the LYONs.

If a U.S. holder purchases LYONs at a discount or premium to the adjusted issue price, the discount will be treated as a positive adjustment and the premium will be treated as a negative adjustment. The U.S. holder must reasonably allocate the

26

adjustment over the remaining term of the LYONs by reference to the accruals of original issue discount at the comparable yield or to the projected payments. It may be reasonable to allocate the adjustment over the remaining term of the LYONs pro rata with the accruals of original issue discount at the comparable yield. Holders should consult their tax advisors regarding those allocations.

SALE, EXCHANGE, CONVERSION OR REDEMPTION

Generally, the sale or exchange of a LYON, or the redemption of a LYON for cash, will result in taxable gain or loss to a U.S. holder. As described above, our calculation of the comparable yield and the schedule of projected payments for the LYONs includes the receipt of common stock upon conversion as a contingent payment with respect to the LYONs. Accordingly, we intend to treat the receipt of our common stock by a U.S. holder upon the conversion of a LYON, or upon the U.S. holder's exercise of a put right where we elect to pay in common stock, as a contingent payment under the CPDI regulations. Under this treatment, conversion or such an exercise of the U.S. holder's put right also would result in taxable gain or loss to the U.S. holder. As described above, holders will be deemed to have agreed to be bound by our determination of the comparable yield and the schedule of projected payments.

The amount of gain or loss on a taxable sale, exchange, conversion or redemption will be equal to the difference between (a) the amount of cash plus the fair market value of any other property received by the U.S. holder, including the fair market value of any of our common stock received, and (b) the U.S. holder's adjusted tax basis in the LYON. A U.S. holder's adjusted tax basis in a LYON will generally be equal to the U.S. holder's original purchase price for the LYON, increased by any interest income previously accrued by the U.S. holder (determined without regard to any adjustments to interest accruals described above, other than adjustments to reflect a discount or premium to the adjusted issue price, if any), and decreased by the amount of any projected payments, as defined above, previously made on the LYONs to the U.S. Holder through such date (without regard to the actual amount paid). Gain recognized upon a sale, exchange, conversion or redemption of a LYON will generally be treated as ordinary interest income; any loss will be ordinary loss to the extent of interest previously included in income, and thereafter, capital loss (which will be long-term if the LYON is held for more than one year). The deductibility of net capital losses by individuals and corporations is subject to limitations.

A U.S. holder's tax basis in our common stock received upon a conversion of a LYON or upon a U.S. holder's exercise of a put right that we elect to pay in our common stock will equal the then current fair market value of such common stock. The U.S. holder's holding period for the common stock received will commence on the day immediately following the date of conversion or redemption.

CONSTRUCTIVE DIVIDENDS

If at any time we were to make a distribution of property to our stockholders that would be taxable to the stockholders as a dividend for United States federal income tax purposes and, in accordance with the anti-dilution provisions of the LYONs, the conversion rate of the LYONs were increased, such increase may be deemed to be the payment of a taxable dividend to holders of the LYONs.

For example, an increase in the conversion rate in the event of distributions of our evidences of indebtedness, or our assets, or an increase in the event of an extraordinary cash dividend may result in deemed dividend treatment to holders of the LYONs, but generally an increase in the event of stock dividends or the distribution of rights to subscribe for common stock would not be so treated.

TREATMENT OF NON-U.S. HOLDERS

Payments of contingent interest made to Non-U.S. holders in excess of the floor amount (i.e., an amount equal to $0.62 multiplied by 4.7301), if any, will not be exempt from United States federal income or withholding tax and, therefore, Non-U.S. holders will be subject to withholding on such payments of contingent interest at a rate of 30%, subject to reduction by an applicable treaty or upon the receipt of a Form W-8ECI from a Non-U.S. holder claiming that the payments are effectively connected with the conduct of a United States trade or business. A Non-U.S. holder that is subject to the withholding tax should consult its tax advisor as to whether it can obtain a refund for a portion of the withholding tax, either on the grounds that some portion of the contingent interest represents a return of principal under the CPDI regulations, or on other grounds.

All other payments on the LYONs made to a Non-U.S. holder, including the portion of any payment of contingent cash interest equal to the floor amount (i.e., the amount equal to $0.62 multiplied by 4.7301), a payment in our common stock pursuant to a conversion, and any gain realized on a sale, exchange, redemption or conversion of the LYONs (other than income or gain attributable to accrued contingent interest payments), will be exempt from United States income or withholding tax PROVIDED that: (i) such Non-U.S. holder does not own, actually, indirectly or constructively, 10% or more of the total combined voting power of all classes of our stock entitled to vote, is not a controlled foreign corporation related, directly or indirectly, to us through stock ownership and is not a bank receiving interest described in section 881(c)(3)(A) of the Code,
(ii) the statement requirement set

27

forth in section 871(h) or section 881(c) of the Code has been fulfilled with respect to the beneficial owner, as discussed below; (iii) such payments and gain are not effectively connected with the conduct by such Non-U.S. holder of a trade or business in the United States; (iv) our common stock continues to be actively traded within the meaning of section 871(h)(4)(C)(v)(I) of the Code (which, for these purposes and subject to certain exceptions, includes trading on the NYSE); and (v) we are not a "United States real property holding corporation." We believe that we are not and do not anticipate becoming a "United States real property holding corporation." However, if a Non-U.S. holder were deemed to have received a constructive dividend (see "--Constructive Dividends" above), the Non-U.S. holder will generally be subject to United States federal withholding tax at a 30% rate on the taxable amount of such dividend, subject to reduction by an applicable treaty or upon the receipt of a Form W-8ECI from the Non-U.S. holder claiming that the deemed receipt of the constructive dividend is effectively connected with the conduct of a United States trade or business.

The statement requirement referred to in the preceding paragraph will be fulfilled if the beneficial owner of a LYON certifies on IRS Form W-8BEN, under penalties of perjury, that it is not a United States person and provides its name and address or otherwise satisfies applicable documentation requirements. If a Non-U.S. holder of the LYONs is engaged in a trade or business in the United States, and if interest on the LYONs is effectively connected with the conduct of such trade or business, the Non-U.S. holder, although exempt from the withholding tax discussed in the preceding paragraphs, will generally be subject to regular United States federal income tax on interest and on any gain realized on the sale, exchange, redemption or conversion of the LYONs in the same manner as if it were a U.S. holder. In lieu of the certificate described in the preceding paragraph, such a Non-U.S. holder will be required to provide to the withholding agent a properly executed IRS Form W-8ECI (or successor form) in order to claim an exemption from withholding tax. In addition, if such a Non-U.S. holder is a foreign corporation, such Non-U.S. holder may be subject to a branch profits tax equal to 30% (or such lower rate provided by an applicable treaty) of its effectively connected earnings and profits for the taxable year, subject to certain adjustments.

BACKUP WITHHOLDING TAX AND INFORMATION REPORTING

Payments of principal, premium, if any, and interest (including original issue discount, tax original issue discount and a payment in common stock pursuant to a conversion of the LYONs) on, and the proceeds of dispositions of, the LYONs may be subject to information reporting and United States federal backup withholding tax if the U.S. holder thereof fails to supply an accurate taxpayer identification number or otherwise fails to comply with applicable United States information reporting or certification requirements. A Non-U.S. holder may be subject to United States backup withholding tax on payments on the LYONs and the proceeds from a sale or other disposition of the LYONs unless the Non-U.S. holder complies with certification procedures to establish that it is not a United States person. Any amounts so withheld will be allowed as a credit against a U.S. holder's United States federal income tax liability and may entitle a holder to a refund, provided the required information is timely furnished to the IRS.

SELLING SECURITY HOLDERS

The LYONs were originally issued by us to Merrill Lynch in a transaction exempt from the registration requirements of the Securities Act and were immediately resold by Merrill Lynch in reliance on Rule 144A to persons who represented to Merrill Lynch that they were qualified institutional buyers. When we refer to "selling security holders" in this prospectus, we mean those persons listed in the table below, as well as the pledgees, donees, assignees, transferees, successors and others who later hold any of the selling security holders interests. The selling security holders may from time to time offer and sell pursuant to this prospectus or a supplement hereto any or all of the LYONs held by that selling security holder and the common stock into which the LYONs are convertible.

The following table sets forth information as of February 13, 2003, with respect to the selling security holders and the principal amounts of LYONs beneficially owned by each selling security holder that may be offered under this prospectus. This information is based on information required to be provided to us by or on behalf of the selling security holders pursuant to questionnaires. No holder of the LYONs may sell the LYONs or shares without furnishing to us a questionnaire setting forth the information specified below. However, as of the date of this prospectus, not every holder has provided to us a questionnaire. Therefore, the heading "Other" in the "Name" column below represents the LYONs and shares held by holders who have not yet returned to us their questionnaire.

The selling security holders may offer all, some or none of the LYONs or common stock into which the LYONs are convertible. In addition, the selling security holders may have sold, transferred or otherwise disposed of all or a portion of their notes since the date on which they provided the information regarding their LYONs in transactions exempt from the registration requirements of the Securities Act. No selling security holder beneficially owns one percent or more of our common stock, assuming conversion of the selling security holders' LYONs.

28

Information concerning the selling security holders may change from time to time and any changed information will be set forth in supplements to this prospectus if and when necessary. In addition, the conversion rate and, therefore, the number of shares of common stock issuable upon conversion of the LYONs, is subject to adjustment under certain circumstances.

(1) Represents shares of common stock issuable upon conversion of LYONs, at the rate of 4.7301 shares of common stock per $1,000 principal amount at maturity of LYONs, that are beneficially owned and offered by the selling security holder. This conversion rate is subject to adjustment, however, as described under "Description of LYONs--Conversion Rights--Conversion Adjustments and Delivery of Common Stock." As a result, the number of shares of common stock issuable upon conversion of the LYONs may increase or decrease in the future.
(2) Assumes that all the LYONs and/or all of the common stock into which the LYONs are convertible are sold. No selling security holder will own more than 1% of the common stock after the offering by the selling stock holder.
(3) Includes any position, office or other material relationship which the selling security holder has had within the past three years with 3M or any of its affiliates.
(4) Assumes that none of the holders of LYONs who have not yet returned their questionnaire beneficially own any other shares of our common stock.

PLAN OF DISTRIBUTION

The LYONs and the common stock are being registered to permit resale of these securities by the selling security holders from time to time after the date of this prospectus. We have agreed, among other things, to bear the expenses incurred in connection with the registration of the LYONs and the common stock covered by this prospectus. We will not receive any of the proceeds from the offering of the LYONs or the common stock by the selling security holders.

The selling security holders and their successors, including their transferees, pledgees or donees or their successors, may sell the LYONs and the common stock into which the LYONs are convertible directly to purchasers or through underwriters, broker-dealers or agents, who may receive compensation in the form of discounts, concessions or commissions from the selling security holders or the purchasers. These discounts, concessions or commissions as to any particular underwriter, broker-dealer or agent may be in excess of those customary in the types of transactions involved.

The LYONs and the common stock into which the LYONs are convertible may be sold in one or more transactions at fixed prices, at prevailing market prices, at prices related to the prevailing market prices, at varying prices determined at the time of sale, or at negotiated prices. These sales may be effected in cross, block or other types of transactions:

* on any national securities exchange or U.S. inter-dealer system of a registered national securities association on which the LYONs or the common stock may be listed or quoted at the time of sale;

* in the over-the-counter market;

* in transactions otherwise than on these exchanges or systems or in the over-the-counter market;

* through the writing of options, whether the options are listed on an options exchange or otherwise;

* through the settlement of short sales; or

* through any other legally available means.

In no event will such method(s) of distribution take the form of an underwritten offering of the LYONs or the common stock into which the LYONs are convertible without our prior written consent. Our common stock is traded on the New York Stock Exchange under the symbol "MMM."

In connection with the sale of the LYONs and the common stock into which the LYONs are convertible, the selling security holders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the LYONs or the common stock into which the LYONs are convertible in the course of hedging the positions they assume. The selling security holders may also sell the LYONs or the common stock into which the LYONs are convertible short and deliver these securities to close out their short positions, or loan or pledge the LYONs or the common stock into which the LYONs are convertible to broker-dealers that in turn may sell these securities.

The aggregate proceeds to the selling security holders from the sale of the LYONs or common stock into which the LYONs are convertible offered by them will be the purchase price of the LYONs or common stock less discounts and commissions, if any. Each of the selling security holders reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of LYONs or common stock to be made directly or through agents. We will not receive any of the proceeds from the sale of the LYONs or the common stock issuable upon conversion of the LYONs.

In order to comply with the securities laws of some states, if applicable, the LYONs and common stock into which the LYONs are convertible may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the LYONs and common stock into which the LYONs are convertible may not be sold unless they have been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.

The selling security holders and any underwriters, broker-dealers or agents that participate in the sale of the LYONs and common stock into which the LYONs are convertible may be "underwriters" within the meaning of Section 2(11) of the Securities Act. Any discounts, commissions, concessions or profit they earn on any resale of the shares may be underwriting discounts and commissions under the Securities Act. Selling security holders who are "underwriters" within the meaning of Section 2(11) of the Securities Act will be subject to the prospectus delivery requirements of the Securities Act. The selling security holders have acknowledged that they understand their obligations to comply with the provisions of the Exchange Act and the rules thereunder relating to stock manipulation, particularly Regulation M.

In addition, any securities covered by this prospectus that qualify for sale pursuant to Rule 144 or Rule 144A of the Securities Act may be sold under Rule 144 or Rule 144A rather than pursuant to this prospectus.

32

To the extent required, the specific LYONs or common stock to be sold, the names of the selling security holders, the respective purchase prices and public offering prices, the names of any agent, dealer or underwriter, and any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement of which this prospectus is a part.

We entered into a registration rights agreement for the benefit of holders of the LYONs to register their LYONs and common stock under applicable federal and state securities laws under specific circumstances and at specific times. The registration rights agreement provides for cross-indemnification of the selling security holders and us and their and our respective directors, officers and controlling persons against specific liabilities in connection with the offer and sale of the LYONs and the common stock, including liabilities under the Securities Act.

LEGAL MATTERS

Certain legal matters relating to the validity of the LYONs and shares of common stock issuable upon conversion of the LYONs have been passed upon for us by Gregg M. Larson, Assistant General Counsel of 3M. Certain matters relating to United States federal taxation have been passed upon for us by Henry W. Gjersdal, Jr., Tax Counsel for 3M.

EXPERTS

The audited financial statements incorporated into this prospectus by reference to our annual report on Form 10-K for the year ended December 31, 2001 have been so incorporated in reliance on the report of PricewaterhouseCoopers LLP, independent accountants, given on the authority of that firm as experts in auditing and accounting.

INDEPENDENT ACCOUNTANTS

With respect to our unaudited interim financial information for the three-month periods ended March 31, 2002 and 2001, the three- and six-month periods ended June 30, 2002 and 2001, and the three- and nine-month periods ended September 30, 2002 and 2001, incorporated by reference in this prospectus, PricewaterhouseCoopers LLP have reported that they have applied limited procedures in accordance with professional standards for a review of such information. However their separate reports dated April 22, 2002, July 22, 2002, and October 21, 2002, and incorporated by reference herein, state that they did not audit and they do not express an opinion on that unaudited interim financial information. Accordingly, the degree of reliance on their report on such information should be restricted in light of the limited nature of the review procedures applied. PricewaterhouseCoopers LLP is not subject to the liability provisions of Section 11 of the Securities Act for their report on the unaudited interim financial information because that report is not a "report" or a "part" of the registration statement prepared or certified by PricewaterhouseCoopers LLP within the meaning of Sections 7 and 11 of the Securities Act.

WE HAVE NOT AUTHORIZED ANY PERSON TO MAKE A STATEMENT THAT DIFFERS FROM WHAT IS IN THIS PROSPECTUS. IF ANY PERSON DOES MAKE A STATEMENT THAT DIFFERS FROM WHAT IS IN THIS PROSPECTUS, YOU SHOULD NOT RELY ON IT. THIS PROSPECTUS IS NOT AN OFFER TO SELL, NOR IS IT SEEKING AN OFFER TO BUY, THESE SECURITIES IN ANY STATE IN WHICH THE OFFER OR SALE IS NOT PERMITTED. THE INFORMATION IN THIS PROSPECTUS IS COMPLETE AND ACCURATE AS OF ITS DATE, BUT THE INFORMATION MAY CHANGE AFTER THAT DATE.

Item 17. Undertakings.

(a) The undersigned Registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by
Section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement, or the most recent post-effective amendment thereof, which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement;

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or 15(d) of the Exchange Act that are incorporated by reference in the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof;

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering;

(b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act of 1934 that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange

II-2


Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

SIGNATURES

"indenture to be qualified" means this Indenture.

"indenture trustee" or "institutional trustee" means the Trustee.

"obligor" on the indenture securities means the Company.

All other TIA terms used in this Indenture that are defined by the TIA, defined by TIA reference to another statute or defined by SEC rule have the meanings assigned to them by such definitions.

SECTION 1.04. Rules of Construction.

Unless the context otherwise requires:

(1) a term has the meaning assigned to it;

6

(2) an accounting term not otherwise defined has the meaning assigned to it in accordance with United States generally accepted accounting principles as in effect from time to time;

(3) "or" is not exclusive;

(4) "including" means including, without limitation; and

(5) words in the singular include the plural, and words in the plural include the singular.

SECTION 1.05. Acts of Holders.

Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments (which may take the form of an electronic writing or messaging or otherwise be in accordance with customary procedures of the Depositary or the Trustee) of substantially similar tenor signed by such Holders in person or by agent duly appointed in writing (which may be in electronic form); and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the "Act" of Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent (either of which may be in electronic form) shall be sufficient for any purpose of this Indenture and conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section.

(a) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution (or electronic delivery) or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing or delivering such instrument or writing acknowledged to such officer the execution thereof (or electronic delivery). Where such execution is by a signer acting in a capacity other than such signer's individual capacity, such certificate or affidavit shall also constitute sufficient proof of such signer's authority. The fact and date of the execution of any such instrument or writing (electronic or otherwise), or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient.

(b) The ownership of Securities shall be proved by the register for the Securities maintained by the Registrar.

(c) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every future Holder of the same Security and the holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Security.

7

(d) If the Company shall solicit from the Holders any request, demand, authorization, direction, notice, consent, waiver or other Act, the Company may, at its option, by or pursuant to a resolution of the Board of Directors, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Company shall have no obligation to do so. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of outstanding Securities have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the outstanding Securities shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date.

ARTICLE 2

THE SECURITIES

SECTION 2.01. Form and Dating.

The Securities and the Trustee's certificate of authentication shall be substantially in the form of Exhibits A-1 and A-2, which are parts of this Indenture. The Securities may have notations, legends or endorsements required by law, stock exchange rule or usage (provided that any such notation, legend or endorsement required by usage is in a form acceptable to the Company). The Company shall provide any such notations, legends or endorsements to the Trustee in writing. Each Security shall be dated the date of its authentication.

(a) Rule 144A Global Securities. Securities offered and sold to qualified institutional buyers as defined in Rule 144A ("QIBs") in reliance on Rule 144A shall be issued, initially in the form of a Rule 144A Global Security, which shall be deposited with the Trustee at its Corporate Trust Office, as custodian for the Depositary and registered in the name of The Depository Trust Company ("DTC") or the nominee thereof (such depositary, or any successor thereto, and any such nominee being hereinafter referred to as the "Depositary"), duly executed by the Company and authenticated by the Trustee as hereinafter provided. The aggregate Principal Amount at Maturity of the Rule 144A Global Securities may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Depositary as hereinafter provided.

(b) IAI Global Securities. Securities transferred by QIBs to institutional accredited investors as defined in Rule 501(a)(1), (2) (3) or (7) under the Securities Act ("Institutional Accredited Investors") shall be issued in the form of an "IAI Global Security", which shall be deposited with the Trustee at its Corporate Trust Office, as custodian for the Depositary and registered in the name of the Depositary, duly executed by the Company and authenticated by the Trustee as hereinafter provided. The aggregate principal amount at maturity of the IAI Global Securities may from time to time be increased or decreased by adjustments made on the records of the Trustee as Depositary as hereinafter provided.

8

(c) Global Securities in General. Each Global Security shall represent such of the outstanding Securities as shall be specified therein and each shall provide that it shall represent the aggregate Principal Amount at Maturity of outstanding Securities from time to time endorsed thereon and that the aggregate Principal Amount at Maturity of outstanding Securities represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, redemptions and conversions. Except as provided in this
Section 2.01, 2.06 or 2.12, owners of beneficial interests in Global Securities will not be entitled to receive physical delivery of Certificated Securities.

Any adjustment of the aggregate Principal Amount at Maturity of a Global Security to reflect the amount of any increase or decrease in the Principal Amount at Maturity of outstanding Securities represented thereby shall be made by the Trustee in accordance with instructions given by the Holder thereof as required by Section 2.12 hereof and shall be made on the records of the Trustee and the Depositary.

(d) Book-Entry Provisions. This Section 2.01(d) shall apply only to Global Securities deposited with or on behalf of the Depositary.

The Company shall execute and the Trustee shall, in accordance with this Section 2.01(d), authenticate and deliver initially one or more Global Securities that (a) shall be registered in the name of the Depositary, (b) shall be delivered by the Trustee to the Depositary or pursuant to the Depositary's instructions and (c) shall bear legends substantially to the following effect:

"UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY TO THE ISSUER OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (AND ANY PAYMENT HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN. TRANSFERS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS, IN WHOLE BUT NOT IN PART, TO NOMINEES OF THE DEPOSITORY TRUST COMPANY OR TO A SUCCESSOR THEREOF OR SUCH SUCCESSOR'S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE RESTRICTIONS SET FORTH IN

9

ARTICLE TWO OF THE INDENTURE REFERRED TO ON THE REVERSE
HEREOF."

(e) Certificated Securities. Securities not issued as interests in the Global Securities will be issued in certificated form substantially in the form of Exhibit A-2 attached hereto.

SECTION 2.02. Execution and Authentication.

The Securities shall be executed on behalf of the Company by any Officer. The signature of the Officer on the Securities may be manual or facsimile.

Securities bearing the manual or facsimile signatures of an individual who was at the time of the execution of the Securities the proper Officer of the Company shall bind the Company, notwithstanding that such individual has ceased to hold such office prior to the authentication and delivery of such Securities or did not hold such office at the date of authentication of such Securities.

No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein duly executed by the Trustee by manual signature of an authorized officer of the Trustee, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder.

Subject to the terms of Section 12.04 and 12.05 hereof, the Trustee shall authenticate and deliver Securities for original issue in an aggregate Principal Amount at Maturity of up to $639,000,000 (subject to Section 2.07 hereof) upon a Company Order without any further action by the Company. The aggregate Principal Amount at Maturity of Securities outstanding at any time may not exceed the amount set forth in the foregoing sentence, except as provided in
Section 2.07.

The Securities shall be issued only in registered form without coupons and only in denominations of $1,000 of Principal Amount at Maturity and any integral multiple thereof.

The Trustee shall have the right to decline to authenticate and deliver any securities under this Section if the Trustee, being advised by counsel, determines that such action may not be lawfully taken or if the Trustee in good faith shall determine that such action would expose the Trustee to personal liability to existing Holders.

SECTION 2.03. Registrar, Paying Agent, Conversion Agent and Bid Solicitation Agent.

The Company shall maintain an office or agency where Securities may be presented for registration of transfer or for exchange for other Securities ("Registrar"), an office or agency where Securities may be presented for purchase or payment ("Paying Agent") and an office or agency where Securities may be presented for conversion into Common Stock ("Conversion Agent"). The Company shall also appoint a bid solicitation agent (the "Bid

10

Solicitation Agent") to act pursuant to Paragraph 5 of the Securities. The Registrar shall keep a register of the Securities and of their transfer and exchange. The Company may have one or more co-registrars, one or more additional paying agents and one or more additional conversion agents. The term Paying Agent includes any additional paying agent, including any named pursuant to
Section 4.05. The term Conversion Agent includes any additional conversion agent, including any named pursuant to Section 4.05.

The Company shall enter into an appropriate agency agreement with any Registrar or co-registrar, Paying Agent, Conversion Agent or Bid Solicitation Agent (other than the Trustee). The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of the name and address of any such agent. If the Company fails to maintain a Registrar, Paying Agent, Conversion Agent or Bid Solicitation Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.07. The Company or any Subsidiary or an Affiliate of either of them may act as Paying Agent, Registrar, Conversion Agent or co-registrar. None of the Company or any Subsidiary or any Affiliate of either of them may act as Bid Solicitation Agent.

The Company initially appoints the Trustee as Registrar, Conversion Agent, Paying Agent and Bid Solicitation Agent in connection with the Securities. The Trustee reserves the right to resign its capacity as Bid Solicitation Agent pursuant to the terms of this Indenture upon not less than sixty (60) days' notice.

SECTION 2.04. Paying Agent to Hold Money and Securities in Trust.

Except as otherwise provided herein, by no later than 10:00
a.m., New York City time, on or prior to each due date of payments in respect of any Security, the Company shall deposit with the Paying Agent a sum of money (in immediately available funds if deposited on the due date) or Common Stock sufficient to make such payments when so becoming due. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Securityholders or the Trustee all money and Common Stock held by the Paying Agent for the making of payments in respect of the Securities and shall notify the Trustee of any default by the Company in making any such payment. At any time during the continuance of any such default, the Paying Agent shall, upon the written request of the Trustee, forthwith pay to the Trustee all money and Common Stock so held in trust. If the Company, a Subsidiary or an Affiliate of either of them acts as Paying Agent, it shall segregate the money and Common Stock held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money and Common Stock held by it to the Trustee and to account for any funds and Common Stock disbursed by it. Upon doing so, the Paying Agent shall have no further liability for the money or Common Stock.

SECTION 2.05. Securityholder Lists.

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Securityholders. If the Trustee is not the Registrar, the Company shall cause to be furnished to the Trustee at least semiannually on November 21 and May 21 a listing of Securityholders dated within 15 days of the date on which the list is furnished and at such other times as the Trustee may request in writing a list in such

11

form and as of such date as the Trustee may reasonably require of the names and addresses of Securityholders.

SECTION 2.06. Transfer and Conversion.

Subject to Section 2.12 hereof,

(a) upon surrender for registration of transfer of any Security, together with a written instrument of transfer satisfactory to the Registrar duly executed by the Securityholder or such Securityholder's attorney duly authorized in writing, at the office or agency of the Company designated as Registrar or co-registrar pursuant to Section 2.03, the Company shall execute, and the Trustee upon receipt of a Company Order shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of any authorized denomination or denominations, of a like aggregate Principal Amount at Maturity. The Company shall not charge a service charge for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to pay all taxes, assessments or other governmental charges that may be imposed in connection with the registration of transfer or exchange of the Securities from the Securityholder requesting such registration of transfer or exchange.

(b) Notwithstanding any provision to the contrary herein, so long as a Global Security remains outstanding and is held by or on behalf of the Depositary, transfers of a Global Security, in whole or in part, shall be made only in accordance with Section 2.12 and this Section 2.06(b). Transfers of a Global Security shall be limited to transfers of such Global Security in whole, or in part, to nominees of the Depositary or to a successor of the Depositary or such successor's nominee.

(c) Successive registrations and registrations of transfers and exchanges as aforesaid may be made from time to time as desired, and each such registration shall be noted on the register for the Securities.

(d) Any Registrar appointed pursuant to Section 2.03 hereof shall provide to the Trustee such information as the Trustee may reasonably require in connection with the delivery by such Registrar of Securities upon registration of transfer or exchange of Securities.

(e) No Registrar shall be required to make registrations of transfer or exchange of Securities during any periods designated in the text of the Securities or in this Indenture as periods during which such registration of transfers and exchanges need not be made.

(f) If Securities are issued upon the registration of transfer, exchange or replacement of Securities subject to restrictions on transfer and bearing the legends set forth on the form of Security attached hereto as Exhibits A-1 and A-2 setting forth such restrictions (collectively, the "Legend"), or if a request is made to remove the Legend on a Security, the Securities so issued shall bear the Legend, or the Legend shall not be removed, as the case may be, unless there is delivered to the Company and the Registrar such satisfactory evidence, which shall include an opinion of counsel, as may be reasonably required by the Company and the Registrar, that neither the Legend nor the restrictions on transfer set forth therein are required to ensure that transfers thereof comply with the provisions of Rule 144A or Rule 144 under

12

the Securities Act or that such Securities are not "restricted" within the meaning of Rule 144 under the Securities Act. Upon (i) provision of such satisfactory evidence, or (ii) notification by the Company to the Trustee and Registrar of the sale of such Security pursuant to a registration statement that is effective at the time of such sale, the Trustee, at the written direction of the Company, shall authenticate and deliver a Security that does not bear the Legend. If the Legend is removed from the face of a Security and the Security is subsequently held by an Affiliate of the Company, the Company shall use its reasonable best efforts to reinstate the Legend.

The Trustee and the Registrar shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among Depositary participants or beneficial owners of interests in any Global Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

SECTION 2.07. Replacement Securities.

(a) If (i) any mutilated Security is surrendered to the Trustee, or (ii) the Company and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Security, and there is delivered to the Company and the Trustee such security or indemnity as may be required by them to save each of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a protected purchaser within the meaning of Article 8 of the Uniform Commercial Code as in effect from time to time in the State of New York (a "Protected Purchaser"), the Company shall execute and upon its written request the Trustee shall authenticate and deliver, in exchange for any such mutilated Security or in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and Principal Amount at Maturity, bearing a number not contemporaneously outstanding.

(b) In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, or is about to be purchased by the Company pursuant to Article 3 hereof, the Company in its discretion may, instead of issuing a new Security, pay or purchase such Security, as the case may be.

(c) Upon the issuance of any new Securities under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

(d) Every new Security issued pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the mutilated, destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and proportionately with any and all other Securities duly issued hereunder.

13

(e) The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

SECTION 2.08. Outstanding Securities; Determinations of Holders' Action.

(a) Securities outstanding at any time are all the Securities authenticated by the Trustee except for those cancelled by it, those paid pursuant to Section 2.07 and delivered to it for cancellation and those described in this Section 2.08 as not outstanding. A Security does not cease to be outstanding because the Company or an Affiliate thereof holds the Security; provided, however, that in determining whether the Holders of the requisite Principal Amount at Maturity of Securities have given or concurred in any request, demand, authorization, direction, notice, consent or waiver hereunder, Securities owned by the Company or any other obligor upon the Securities or any Affiliate of the Company or such other obligor shall be disregarded and deemed not to be outstanding, except that, in determining whether the Trustee shall be protected in relying upon any such request, demand, authorization, direction, notice, consent or waiver, only Securities which a Responsible Officer of the Trustee actually knows to be so owned shall be so disregarded. Subject to the foregoing, only Securities outstanding at the time of such determination shall be considered in any such determination (including, without limitation, determinations pursuant to Articles 6 and 9).

(b) If a Security is replaced pursuant to Section 2.07, the replaced Security ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to each of them that the replaced Security is held by a Protected Purchaser.

(c) If the Paying Agent holds, in accordance with this Indenture, on a Redemption Date, or on the Business Day following the Purchase Date or a Change in Control Purchase Date, or on Stated Maturity, money or securities, if permitted hereunder, sufficient to pay Securities payable on that date, then immediately after such Redemption Date, Purchase Date, Change in Control Purchase Date or Stated Maturity, as the case may be, such Securities shall cease to be outstanding and Original Issue Discount and interest (including contingent interest), if any, on such Securities shall cease to accrue whether or not the Security is delivered to the Paying Agent; provided, that if such Securities are to be redeemed, notice of such redemption has been duly given pursuant to this Indenture.

(d) If a Security is converted in accordance with Article 10, then from and after the time of conversion on the Conversion Date, such Security shall cease to be outstanding and Original Issue Discount and interest (including contingent interest), if any, shall cease to accrue on such Security.

SECTION 2.09. Temporary Securities.

(a) Pending the preparation of definitive Securities, the Company may execute, and the Trustee upon receipt of a Company Order shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and

14

other variations as the officers executing such Securities may determine, as conclusively evidenced by their execution of such Securities.

(b) If temporary Securities are issued, the Company will cause definitive Securities to be prepared without unreasonable delay. After the preparation of definitive Securities, the temporary Securities shall be exchangeable for definitive Securities upon surrender of the temporary Securities at the office or agency of the Company designated for such purpose pursuant to Section 2.03, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities, the Company shall execute and the Trustee upon receipt of a Company Order shall authenticate and deliver in exchange therefor a like Principal Amount at Maturity of definitive Securities of authorized denominations. Until so exchanged the temporary Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Securities.

SECTION 2.10. Cancellation.

All Securities surrendered for payment, purchase by the Company pursuant to Article 3, conversion, redemption or registration of transfer or exchange shall, if surrendered to any person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly cancelled by the Trustee. The Company may not issue new Securities to replace Securities it has paid or delivered to the Trustee for cancellation or that any Holder has converted pursuant to Article 10. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall be disposed of by the Trustee in accordance with the Trustee's customary procedure.

SECTION 2.11. Persons Deemed Owners.

Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of the Security or the payment of any Redemption Price, Purchase Price or Change in Control Purchase Price in respect thereof, and interest (including contingent interest, if any) thereon, for the purpose of conversion and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

SECTION 2.12. Global Securities.

(a) Notwithstanding any other provisions of this Indenture or the Securities, (A) transfers of a Global Security, in whole or in part, shall be made only in accordance with Section 2.06 and

15

Section 2.12(a)(i), (B) transfer of a beneficial interest in a Rule 144A Global Security for a beneficial interest in an IAI Global Security shall comply with
Section 2.06 and Section 2.12(a)(ii) below, and (C) transfers of beneficial interests in an IAI Global Security shall comply with Section 2.06 and Section 2.12(a)(iii) and (iv) below.

(i) TRANSFER OF GLOBAL SECURITY. A Global Security may not be transferred, in whole or in part, to any Person other than the Depositary or a nominee or any successor thereof, and no such transfer to any such other Person may be registered; provided that this clause (i) shall not prohibit any transfer of a Security that is issued in exchange for a Global Security but is not itself a Global Security. No transfer of a Security to any Person shall be effective under this Indenture or the Securities unless and until such Security has been registered in the name of such Person. Nothing in this Section 2.12(a)(i) shall prohibit or render ineffective any transfer of a beneficial interest in a Global Security effected in accordance with the other provisions of this Section 2.12(a).

(ii) RESTRICTIONS ON TRANSFER OF A BENEFICIAL INTEREST IN A RULE 144A GLOBAL SECURITY FOR A BENEFICIAL INTEREST IN AN IAI GLOBAL SECURITY. A beneficial interest in a Rule 144A Global Security may not be exchanged for a beneficial interest in an IAI Global Security except upon satisfaction of the requirements set forth below. Upon receipt by the Trustee of a request for transfer of a beneficial interest in a Rule 144A Global Security in accordance with Applicable Procedures for a beneficial interest in an IAI Global Security in the form satisfactory to the Trustee, together with:

(a) so long as the Securities are Restricted Securities, certification, in the form set forth in Exhibit B-1, and, if requested by the Company or the Registrar, certification in the form set forth in Exhibit B-2, that such beneficial interest in the Rule 144A Global Security is being transferred to an Institutional Accredited Investor in accordance with subparagraphs (a)(1), (2),
(3) or (7) of Rule 501 under the Securities Act;

(b) written instructions to the Trustee to make an adjustment on its books and records with respect to such Rule 144A Global Security to reflect a decrease in the aggregate Principal Amount at Maturity of the Securities represented by the Rule 144A Global Security, and a corresponding adjustment on such books and records to reflect a corresponding increase in the aggregate Principal Amount at Maturity of the Securities represented by the IAI Global Security, such instructions to contain information regarding the Depositary accounts to be credited with such decrease and increase, respectively; and

(c) if the Company or Trustee so requests, an opinion of counsel or other evidence reasonably satisfactory to them as to the compliance with the restrictions set forth in the Legend,

16

then the Trustee shall (y) debit or cause to be debited from the account of the Person who has transferred their beneficial interest in such Rule 144A Global Security a beneficial interest in the Rule 144A Global Security equal to the Principal Amount at Maturity of the increase in the beneficial interest in the IAI Global Security and (z) shall credit or cause to be credited to the account of the Person who is the transferee of such beneficial interest a corresponding beneficial interest in the IAI Global Security.

(iii) TRANSFER OF BENEFICIAL INTERESTS IN IAI GLOBAL SECURITIES. Upon a request to the Trustee to transfer a beneficial interest in an IAI Global Security other than into an interest in a Rule 144A Global Security, such transfer may only be effected if such transfer is pursuant to an effective registration statement under the Securities Act or pursuant to clause (A) or (B) below, and, upon request by the Company or the Trustee, are accompanied by the following additional information and documents, as applicable:

(A) if such beneficial interests are being transferred to the Company, a certification to that effect; or

(B) if such beneficial interests are being transferred pursuant to an exemption from registration (i) a certification to that effect (in the form set forth in Exhibit B-1 and B-2, if applicable) and (ii) if the Company or Trustee so request, an opinion of counsel or other evidence reasonably satisfactory to them as to the compliance with the restrictions set forth in the Legend.

(iv) RESTRICTIONS ON TRANSFER OF A BENEFICIAL INTEREST IN AN IAI GLOBAL SECURITY FOR A BENEFICIAL INTEREST IN A RULE 144A GLOBAL SECURITY. A beneficial interest in an IAI Global Security may not be exchanged for a beneficial interest in a Rule 144A Global Security except upon satisfaction of the requirements set forth below.

Upon request to the Trustee for transfer of a beneficial interest in an IAI Global Security for a beneficial interest in a Rule 144A Global, together with, if required by the Trustee:

(a) so long as the Securities are Restricted Securities, certification, in the form set forth in Exhibit B-1, that such beneficial interest in an IAI Global Security is being transferred to a QIB in accordance with Rule 144A; and

(b) written instructions directing the Trustee to make an adjustment on its books and records with respect to such Rule 144A Global Security to reflect an increase in the aggregate Principal Amount at Maturity of the Securities represented by the Rule 144A Global Security, and a corresponding adjustment on such books and

17

records to reflect a corresponding decrease in the aggregate Principal Amount at Maturity of the Securities represented by the IAI Global Security, such instructions to contain information regarding the Depositary accounts to be credited with such increase and decrease, respectively,

then the Trustee shall (y) credit or cause to be credited to the account of the Person who has transferred their beneficial interest in such IAI Global Security a beneficial interest in the Rule 144A Global Security equal to the Principal Amount at Maturity of the beneficial interest in the IAI Global Security so transferred and (z) shall debit or cause to be debited from the account of the Person who is the transferee of such beneficial interest a corresponding beneficial interest in the IAI Global Security so transferred. If no Global Securities are then outstanding, the Company shall issue and the Trustee upon receipt of a Company Order shall authenticate a new Global Security in the appropriate Principal Amount at Maturity.

(b) Subject to the succeeding paragraph, every Security shall be subject to the restrictions on transfer provided in the Legend including the delivery of an Opinion of Counsel, if so provided. Whenever any Restricted Security is presented or surrendered for registration of transfer or for exchange for a Security registered in a name other than that of the Holder, such Security must be accompanied by a certificate in substantially the form set forth in Exhibit B-1, dated the date of such surrender and signed by the Holder of such Security, as to compliance with such restrictions on transfer. The Registrar shall not be required to accept for such registration of transfer or exchange any Security not so accompanied by a properly completed certificate.

(c) The restrictions imposed by the Legend upon the transferability of any Security shall cease and terminate when such Security has been sold pursuant to an effective registration statement under the Securities Act or transferred in compliance with Rule 144 under the Securities Act (or any successor provision thereto) or, if earlier, upon the expiration of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision). Any Security as to which such restrictions on transfer shall have expired in accordance with their terms or shall have terminated may, upon a surrender of such Security for exchange to the Registrar in accordance with the provisions of this Section 2.12 (accompanied, in the event that such restrictions on transfer have terminated by reason of a transfer in compliance with Rule 144 or any successor provision, by an opinion of counsel having substantial experience in practice under the Securities Act and otherwise reasonably acceptable to the Company, addressed to the Company, the Trustee and the Registrar and in form acceptable to the Company, to the effect that the transfer of such Security has been made in compliance with Rule 144 or such successor provision), be exchanged for a new Security, of like tenor and aggregate Principal Amount at Maturity, which shall not bear the restrictive Legend. The Company shall inform the Trustee of the effective date of any registration statement registering the Securities under the Securities Act. The Trustee and the Registrar shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the aforementioned Opinion of Counsel or registration statement.

18

(d) As used in the preceding two paragraphs of this Section 2.12, the term "transfer" encompasses any sale, pledge, transfer, hypothecation or other disposition of any Security.

(e) The provisions of clauses (1), (2), (3) and (4) below shall apply only to Global Securities:

(1) Notwithstanding any other provisions of this Indenture or the Securities, except as provided in Section 2.12(a)(ii), a Global Security shall not be exchanged in whole or in part for a Security registered in the name of any Person other than the Depositary or one or more nominees thereof, provided that a Global Security may be exchanged for Securities registered in the names of any person designated by the Depositary in the event that (i) the Depositary has notified the Company that it is unwilling or unable to continue as Depositary for such Global Security or such Depositary has ceased to be a "clearing agency" registered under the Exchange Act, and a successor Depositary is not appointed by the Company within 90 days, (ii) the Company decides to discontinue use of the system of book-entry transfer through DTC (or any successor depositary); or (iii) an Event of Default has occurred and is continuing with respect to the Securities. Any Global Security exchanged pursuant to clause (i) or (ii) above shall be so exchanged in whole and not in part, and any Global Security exchanged pursuant to clause (iii) above may be exchanged in whole or from time to time in part as directed by the Depositary. Any Security issued in exchange for a Global Security or any portion thereof shall be a Global Security; provided that any such Security so issued that is registered in the name of a Person other than the Depositary or a nominee thereof shall not be a Global Security.

(2) Securities issued in exchange for a Global Security or any portion thereof shall be issued in definitive, fully registered form, without interest coupons, shall have an aggregate Principal Amount at Maturity equal to that of such Global Security or portion thereof to be so exchanged, shall be registered in such names and be in such authorized denominations as the Depositary shall designate and shall bear the applicable legends provided for herein. Any Global Security to be exchanged in whole shall be surrendered by the Depositary to the Trustee, as Registrar. With regard to any Global Security to be exchanged in part, either such Global Security shall be so surrendered for exchange or, if the Trustee is acting as custodian for the Depositary or its nominee with respect to such Global Security, the Principal Amount at Maturity thereof shall be reduced, by an amount equal to the portion thereof to be so exchanged, by means of an appropriate

19

adjustment made on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and deliver the Security issuable on such exchange to or upon the order of the Depositary or an authorized representative thereof.

(3) Subject to the provisions of clause (5) below, the registered Holder may grant proxies and otherwise authorize any Person, including Agent Members (as defined below) and persons that may hold interests through Agent Members, to take any action which a holder is entitled to take under this Indenture or the Securities.

(4) In the event of the occurrence of any of the events specified in clause (1) above, the Company will promptly make available to the Trustee a reasonable supply of Certificated Securities in definitive, fully registered form, without interest coupons.

(5) Neither any members of, or participants in, the Depositary (collectively, the "Agent Members") nor any other Persons on whose behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Security registered in the name of the Depositary or any nominee thereof, or under any such Global Security, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and holder of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or such nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any other person on whose behalf an Agent Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a holder of any Security.

SECTION 2.13. CUSIP Numbers.

The Company in issuing the Securities may use "CUSIP" numbers (if then generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the CUSIP numbers.

20

ARTICLE 3

REDEMPTION AND PURCHASES

SECTION 3.01. Right to Redeem; Notices to Trustee.

The Company, at its option, may redeem the Securities in accordance with the provisions of paragraphs 6 and 8 of the Securities. If the Company elects to redeem Securities pursuant to paragraph 6 of the Securities, it shall notify the Trustee in writing of the Redemption Date, the Principal Amount at Maturity of Securities to be redeemed, the CUSIP number of Securities to be redeemed, the Redemption Price and the amount of contingent interest, if any, payable on the Redemption Date.

The Company shall give the notice to the Trustee provided for in this Section 3.01 by a Company Order, at least 30 days before the Redemption Date (unless a shorter notice shall be satisfactory to the Trustee).

SECTION 3.02. Selection of Securities to Be Redeemed.

If less than all the Securities are to be redeemed, the Trustee shall select the Securities to be redeemed pro rata or by lot or by any other method selected by the Trustee in its sole discretion (so long as such method is not prohibited by the rules of any stock exchange on which the Securities are then listed). The Trustee shall make the selection at least 30 days but not more than 60 days before the Redemption Date from outstanding Securities not previously called for redemption.

Securities and portions of them the Trustee selects shall be in Principal Amounts at Maturity of $1,000 or an integral multiple of $1,000. Provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption. The Trustee shall notify the Company promptly of the Securities or portions of Securities to be redeemed.

If any Security selected for partial redemption is converted in part before termination of the conversion right with respect to the portion of the Security so selected, the converted portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption. Securities which have been converted during a selection of Securities to be redeemed may be treated by the Trustee as outstanding for the purpose of such selection.

SECTION 3.03. Notice of Redemption.

At least 30 days but not more than 60 days before a Redemption Date, the Company shall mail a notice of redemption by first-class mail, postage prepaid, to each Holder of Securities to be redeemed.

The notice shall identify the Securities to be redeemed and shall state:

(1) the Redemption Date;

21

(2) the Redemption Price and, to the extent known at the time of such notice, the amount of contingent interest, if any, payable on the Redemption Date;

(3) the Conversion Rate;

(4) the name and address of the Paying Agent and Conversion Agent;

(5) that Securities called for redemption may be converted at any time before the close of business on the second Business Day immediately preceding the Redemption Date;

(6) that Holders who want to convert Securities must satisfy the requirements set forth in paragraph 9 of the Securities;

(7) that Securities called for redemption must be surrendered to the Paying Agent to collect the Redemption Price and contingent interest, if any; (8) if fewer than all the outstanding Securities are to be redeemed, the certificate number and Principal Amounts at Maturity of the particular Securities to be redeemed;

(9) that, unless the Company defaults in making payment of such Redemption Price and contingent interest, if any, Original Issue Discount and contingent interest, if any, on Securities called for redemption will cease to accrue on and after the Redemption Date and the Securities will cease to be convertible; and

(10) the CUSIP number of the Securities.

At the Company's request, the Trustee shall give the notice of redemption in the Company's name and at the Company's expense, provided that the Company makes such request at least five Business Days (unless a shorter period shall be satisfactory to the Trustee) prior to the date such notice of redemption must be mailed.

SECTION 3.04. Effect of Notice of Redemption.

Once notice of redemption is given, Securities called for redemption become due and payable on the Redemption Date and at the Redemption Price (together with accrued contingent interest, if any, to but not including the date of redemption) stated in the notice except for Securities which are converted in accordance with the terms of this Indenture. Upon surrender to the Paying Agent, such Securities shall be paid at the Redemption Price (together with accrued contingent interest, if any, to but not including the date of redemption) stated in the notice.

22

SECTION 3.05. Deposit of Redemption Price.

Prior to 10:00 a.m. (New York City time) on any Redemption Date, the Company shall deposit with the Paying Agent (or if the Company or a Subsidiary or an Affiliate of either of them is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the Redemption Price of, and any accrued and unpaid contingent interest to but not including the date of redemption with respect to, all Securities to be redeemed on that date other than Securities or portions of Securities called for redemption which on or prior thereto have been delivered by the Company to the Trustee for cancellation or have been converted. The Paying Agent shall as promptly as practicable return to the Company any money, not required for that purpose because of conversion of Securities pursuant to Article 10. If such money is then held by the Company in trust and is not required for such purpose it shall be discharged from such trust.

SECTION 3.06. Securities Redeemed in Part.

Upon surrender of a Security that is redeemed in part, the Company shall execute and the Trustee shall authenticate and deliver to the Holder a new Security in an authorized denomination equal in Principal Amount at Maturity to the unredeemed portion of the Security surrendered.

SECTION 3.07. Conversion Arrangement on Call for Redemption.

In connection with any redemption of Securities, the Company may arrange for the purchase and conversion of any Securities called for redemption by an agreement with one or more investment banks or other purchasers to purchase such Securities by paying to the Trustee in trust for the Securityholders, on or prior to 10:00 a.m. New York City time on the Redemption Date, an amount that, together with any amounts deposited with the Trustee by the Company for the redemption of such Securities, is not less than the Redemption Price of, and any accrued and unpaid contingent interest with respect to, such Securities. Notwithstanding anything to the contrary contained in this Article 3, the obligation of the Company to pay the Redemption Prices of such Securities shall be deemed to be satisfied and discharged to the extent such amount is so paid by such purchasers. If such an agreement is entered into, any Securities not duly surrendered for conversion by the Holders thereof may, at the option of the Company, be deemed, to the fullest extent permitted by law, acquired by such purchasers from such Holders and (notwithstanding anything to the contrary contained in Article 10) surrendered by such purchasers for conversion, all as of immediately prior to the close of business on the Business Day prior to the Redemption Date, subject to payment of the above amount as aforesaid. The Trustee shall hold and pay to the Holders whose Securities are selected for redemption any such amount paid to it for purchase and conversion in the same manner as it would moneys deposited with it by the Company for the redemption of Securities. Without the Trustee's prior written consent, no arrangement between the Company and such purchasers for the purchase and conversion of any Securities shall increase or otherwise affect any of the powers, duties, responsibilities or obligations of the Trustee as set forth in this Indenture, and the Company agrees to indemnify the Trustee from, and hold it harmless against, any loss, liability or expense arising out of or in connection with any such arrangement for the purchase and conversion of any Securities between the Company and such purchasers, including the costs and expenses incurred by the Trustee in the defense of any claim or liability arising out of or in connection with the

23

exercise or performance of any of its powers, duties, responsibilities or obligations under this Indenture.

SECTION 3.08. Purchase of Securities at Option of the Holder.

(a) General. Securities shall be purchased by the Company pursuant to paragraph 7 of the Securities at the option of the Holder thereof, upon:

(1) delivery to the Paying Agent by the Holder of a written notice of purchase (a "Purchase Notice") at any time from the opening of business on the date that is 20 Business Days prior to a Purchase Date until the close of business on the Business Day immediately preceding such Purchase Date stating:

(A) the certificate number of the Security which the Holder will deliver to be purchased,

(B) the portion of the Principal Amount at Maturity of the Security which the Holder will deliver to be purchased, which portion must be a Principal Amount at Maturity of $1,000 or an integral multiple thereof,

(C) that such Security shall be purchased as of the Purchase Date pursuant to the terms and conditions specified in paragraph 7 of the Securities and in this Indenture, and

(D) in the event the Company elects, pursuant to
Section 3.08(b), to pay the Purchase Price to be paid as of such Purchase Date, in whole or in part, in shares of Common Stock but such portion of the Purchase Price shall ultimately be payable to such Holder entirely in cash because any of the conditions to payment of the Purchase Price in Common Stock is not satisfied prior to the close of business on such Purchase Date, as set forth in Section 3.08(d), whether such Holder elects (i) to withdraw such Purchase Notice as to some or all of the Securities to which such Purchase Notice relates (stating the Principal Amount at Maturity and certificate numbers of the Securities as to which such withdrawal shall relate), or (ii) to receive cash in respect of the entire Purchase Price for all Securities (or portions thereof) to which such Purchase Notice relates; and

(2) delivery of such Security to the Paying Agent prior to, on or after the Purchase Date (together with all necessary endorsements) at the offices of the Paying Agent, such delivery being a condition to receipt by the Holder of the Purchase Price therefor; provided, however, that such Purchase Price shall be so paid pursuant to this
Section 3.08 only if the Security so delivered to the Paying Agent shall conform in all respects to the description thereof in the related Purchase Notice, as determined by the Company.

If a Holder, in such Holder's Purchase Notice and in any written notice of withdrawal delivered by such Holder pursuant to the terms of
Section 3.10, fails to indicate such Holder's choice with respect to the election set forth in clause (D) of Section 3.08(a)(1), such

24

Holder shall be deemed to have elected to receive cash in respect of the Purchase Price for all Securities subject to such Purchase Notice in the circumstances set forth in such clause (D).

The Company shall purchase from the Holder thereof, pursuant to this Section 3.08, a portion of a Security if the Principal Amount at Maturity of such portion is $1,000 or an integral multiple of $1,000. Provisions of this Indenture that apply to the purchase of all of a Security also apply to the purchase of such portion of such Security.

Any purchase by the Company contemplated pursuant to the provisions of this Section 3.08 shall be consummated by the delivery of the consideration to be received by the Holder (including accrued and unpaid contingent interest, if any) promptly following the later of the Purchase Date and the time of delivery of the Security.

Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Purchase Notice contemplated by this Section 3.08(a) shall have the right to withdraw such Purchase Notice at any time prior to the close of business on the Purchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 3.10.

The Paying Agent shall promptly notify the Company of the receipt by it of any Purchase Notice or written notice of withdrawal thereof.

(b) Company's Right to Elect Manner of Payment of Purchase Price. The Securities to be purchased pursuant to Section 3.08(a) may be paid for, at the election of the Company, in U.S. legal tender ("cash") or Common Stock, or in any combination of cash and Common Stock, subject to the conditions set forth in Sections 3.08(c) and (d). The Company shall designate, in the Company Notice delivered pursuant to Section 3.08(e), whether the Company will purchase the Securities for cash or Common Stock, or, if a combination thereof, the percentages of the Purchase Price of Securities in respect of which it will pay in cash or Common Stock; provided that the Company will pay cash for fractional interests in Common Stock. For purposes of determining the existence of potential fractional interests, all Securities subject to purchase by the Company held by a Holder shall be considered together (no matter how many separate certificates are to be presented). Each Holder whose Securities are purchased pursuant to this Section 3.08 shall receive the same percentage of cash or Common Stock in payment of the Purchase Price for such Securities, except (i) as provided in Section 3.08(d) with regard to the payment of cash in lieu of fractional shares of Common Stock and (ii) in the event that the Company is unable to purchase the Securities of a Holder or Holders for Common Stock because any necessary qualifications or registrations of the Common Stock under applicable state securities laws cannot be obtained, the Company may purchase the Securities of such Holder or Holders for cash. The Company may not change its election with respect to the consideration (or components or percentages of components thereof) to be paid once the Company has given its Company Notice to Securityholders except pursuant to this Section 3.08(b) or pursuant to Section 3.08(d) in the event of a failure to satisfy, prior to the close of business on the Purchase Date, any condition to the payment of the Purchase Price, in whole or in part, in Common Stock.

At least three Business Days before the Company Notice Date, the Company shall deliver an Officers' Certificate to the Trustee specifying:

25

(i) the manner of payment selected by the Company,

(ii) the information required by Section 3.08(e),

(iii) if the Company elects to pay the Purchase Price, or a specified percentage thereof, in Common Stock, that the conditions to such manner of payment set forth in
Section 3.08(d) have been or will be complied with, and

(iv) whether the Company desires the Trustee to give the Company Notice required by Section 3.08(e).

(c) Purchase with Cash. On each Purchase Date, at the option of the Company, the Purchase Price of Securities in respect of which a Purchase Notice pursuant to Section 3.08(a) has been given, or a specified percentage thereof, may be paid by the Company with cash equal to the aggregate Purchase Price of such Securities. If the Company elects to purchase Securities with cash, the Company Notice, as provided in Section 3.08(e), shall be sent to Holders (and to beneficial owners as required by applicable law) not less than 20 Business Days prior to such Purchase Date (the "Company Notice Date").

(d) Payment by Issuance of Common Stock. On each Purchase Date, at the option of the Company, the Purchase Price of Securities in respect of which a Purchase Notice pursuant to Section 3.08(a) has been given, or a specified percentage thereof, may be paid by the Company by the issuance of a number of shares of Common Stock equal to the quotient obtained by dividing (i) the amount of cash to which the Securityholders would have been entitled had the Company elected to pay all or such specified percentage, as the case may be, of the Purchase Price of such Securities in cash by (ii) the Market Price of a share of Common Stock, subject to the next succeeding paragraph.

The Company will not issue a fractional share of Common Stock in payment of the Purchase Price. Instead the Company will pay cash for the current market value of the fractional share. The current market value of a fraction of a share shall be determined by multiplying the Market Price by such fraction and rounding the product to the nearest whole cent. It is understood that if a Holder elects to have more than one Security purchased, the number of shares of Common Stock shall be based on the aggregate amount of Securities to be purchased.

If the Company elects to purchase the Securities by the issuance of shares of Common Stock, the Company Notice, as provided in Section 3.08(e), shall be sent to the Holders (and to beneficial owners as required by applicable law) not later than the Company Notice Date.

The Company's right to exercise its election to purchase the Securities pursuant to Section 3.08 through the issuance of shares of Common Stock shall be conditioned upon:

(i) the Company's not having given its Company Notice of an election to pay entirely in cash and its giving of timely Company Notice of election to purchase all or a specified percentage of the Securities with Common Stock as provided herein;

26

(ii) the shares of Common Stock having been admitted for listing or admitted for listing subject to notice of issuance on the principal United States securities exchange on which the Common Stock is then listed or causing such shares of Common Stock to be quoted on the Nasdaq National Market System if not so quoted;

(iii) the registration of the shares of Common Stock to be issued in respect of the payment of the Purchase Price under the Securities Act of 1933, as amended (the "Securities Act"), or the Securities Exchange Act of 1934, as amended (the "Exchange Act"), in each case, if required;

(iv) any necessary qualification or registration under applicable state securities laws or the availability of an exemption from such qualification and registration; and

(v) the receipt by the Trustee of an Officers' Certificate and an Opinion of Counsel each stating that (A) the terms of the issuance of the Common Stock are in conformity with this Indenture and (B) the shares of Common Stock to be issued by the Company in payment of the Purchase Price in respect of Securities have been duly authorized and, when issued and delivered pursuant to the terms of this Indenture in payment of the Purchase Price in respect of the Securities, will be validly issued, fully paid and non-assessable and, to the best of such counsel's knowledge, free from preemptive rights, and, in the case of such Officers' Certificate, stating that conditions (i), (ii),
(iii) and (iv) above and the condition set forth in the second succeeding sentence have been satisfied and, in the case of such Opinion of Counsel, stating that conditions (ii), (iii) and (iv) above have been satisfied.

Such Officers' Certificate shall also set forth the number of shares of Common Stock to be issued for each $1,000 Principal Amount at Maturity of Securities and the Sale Price of a share of Common Stock on each Trading Day during the period for which the Market Price is calculated. The Company may pay the Purchase Price (or any portion thereof) in Common Stock only if the information necessary to calculate the Market Price is published in a daily newspaper of national circulation. If the foregoing conditions are not satisfied with respect to a Holder or Holders prior to the close of business on the Purchase Date and the Company has elected to purchase the Securities pursuant to this Section 3.08 through the issuance of shares of Common Stock, the Company shall pay the entire Purchase Price of the Securities of such Holder or Holders in cash.

The "Market Price" means the average of the Sale Prices of the Common Stock for the five Trading Day period ending on the third Business Day prior to the applicable Purchase Date (if the third Business Day prior to the applicable Purchase Date is a Trading Day, otherwise the Five Trading Day period shall end on the last Trading Day prior to such third Business Day), appropriately adjusted to take into account the occurrence, during the period commencing on the first of such Trading Days during such five Trading Day period and ending on such Purchase Date, of any event described in Section 10.06, 10.07 or 10.08; subject, however, to the conditions set forth in Sections 10.09 and 10.10.

27

The "Sale Price" of the Common Stock on any date means the closing per share sale price (or, if no closing sale price is reported, the average of the bid and ask prices or, if more than one in either case, the average of the average bid and average ask prices) on such date as reported in composite transactions on the New York Stock Exchange or such other principal United States securities exchange on which the Common Stock is traded or, if the Common Stock is not listed on a United States national or regional securities exchange, (i) as reported by the National Association of Securities Dealers Automated Quotation System or by the National Quotation Bureau Incorporated, or
(ii) if such bid and ask prices are not reported by the National Association of Securities Dealers Automated Quotation System or by the National Quotation Bureau Incorporated, in a manner to be determined by the Company on the basis of such quotation as the Company considers appropriate in its sole and absolute discretion.

(e) Notice of Election. The Company's notice of election to purchase with cash or Common Stock or any combination thereof shall be sent to the Holders (and to beneficial owners as required by applicable law) in the manner provided in Section 12.02 at the time specified in Section 3.08(c) or
(d), as applicable (the "Company Notice"). Such Company Notice shall state the manner of payment elected and shall contain the following information: In the event the Company has elected to pay the Purchase Price (or a specified percentage thereof) with Common Stock, the Company Notice shall:

(1) state that each Holder will receive Common Stock with a Market Price determined as of a specified date prior to the Purchase Date equal to such specified percentage of the Purchase Price of the Securities held by such Holder (except any cash amount to be paid in lieu of fractional shares);

(2) set forth the method of calculating the Market Price of the Common Stock; and

(3) state that because the Market Price of Common Stock will be determined prior to the Purchase Date, Holders will bear the market risk with respect to the value of the Common Stock to be received from the date such Market Price is determined to the Purchase Date.

In any case, each Company Notice shall include a form of Purchase Notice to be completed by a Securityholder and shall state:

(i) the Purchase Price, the Conversion Rate and, to the extent known at the time of such notice, the amount of contingent interest, if any, that will be accrued and payable with respect to the Securities as of the Purchase Date;

(ii) the name and address of the Paying Agent and the Conversion Agent;

(iii) that Securities as to which a Purchase Notice has been given may be converted pursuant to Article 10 hereof only if the applicable Purchase Notice has been withdrawn in accordance with the terms of this Indenture;

28

(iv) that Securities must be surrendered to the Paying Agent to collect payment of the Purchase Price and contingent interest, if any;

(v) that the Purchase Price for any Security as to which a Purchase Notice has been given and not withdrawn, together with any accrued contingent interest payable with respect thereto, will be paid promptly following the later of the Purchase Date and the time of surrender of such Security as described in (iv);

(vi) the procedures the Holder must follow to exercise rights under Section 3.08 and a brief description of those rights;

(vii) briefly, the conversion rights of the Securities;

(viii) the procedures for withdrawing a Purchase Notice (including, without limitation, for a conditional withdrawal pursuant to the terms of Section 3.08(a)(1)(D) or
Section 3.10);

(ix) that, unless the Company defaults in making payment of such Purchase Price and contingent interest, if any, Original Issue Discount and contingent interest, if any, on Securities surrendered for purchase will cease to accrue on and after the Purchase Date; and

(x) the CUSIP number of the Securities.

At the Company's request, the Trustee shall give such Company Notice in the Company's name and at the Company's expense; provided, however, that, in all cases, the text of such Company Notice shall be prepared by the Company.

Upon determination of the actual number of shares of Common Stock to be delivered for each $1,000 Principal Amount at Maturity of Securities, the Company will issue a press release and publish such determination on the Company's web site on the World Wide Web or through such other public medium as the Company may use at that time.

(f) Covenants of the Company. All shares of Common Stock delivered upon purchase of the Securities shall be newly issued shares or treasury shares, shall be duly authorized, validly issued, fully paid and nonassessable and shall be free from preemptive rights and free of any lien or adverse claim.

(g) Procedure upon Purchase. The Company shall deposit cash (in respect of a cash purchase under Section 3.08(c) or for fractional interests or contingent interest, as applicable) or shares of Common Stock, or a combination thereof, as applicable, at the time and in the manner as provided in
Section 3.11, sufficient to pay the aggregate Purchase Price of, and any accrued and unpaid contingent interest with respect to, all Securities to be purchased pursuant to this Section 3.08. As soon as practicable after the Purchase Date, the Company shall deliver to each Holder entitled to receive Common Stock through the Paying Agent, a certificate for the number of full shares of Common Stock issuable in payment of the Purchase Price and cash in lieu of any fractional interests. The person in whose name the certificate for Common Stock is registered shall be treated as a holder of record of shares of Common Stock on the

29

Business Day following the Purchase Date. No payment or adjustment will be made for dividends on the Common Stock the record date for which occurred on or prior to the Purchase Date.

(h) Taxes. If a Holder of a Security is paid in Common Stock, the Company shall pay any documentary, stamp or similar issue or transfer tax due on such issue of shares of Common Stock. However, the Holder shall pay any such tax which is due because the Holder requests the shares of Common Stock to be issued in a name other than the Holder's name. The Paying Agent may refuse to deliver the certificates representing the Common Stock being issued in a name other than the Holder's name until the Paying Agent receives a sum sufficient to pay any tax which will be due because the shares of Common Stock are to be issued in a name other than the Holder's name. Nothing herein shall preclude any income tax withholding required by law or regulations.

SECTION 3.09. Purchase of Securities at Option of the Holder upon Change in Control.

(a) If on or prior to the date specified in paragraph 7 of the Securities, there shall have occurred a Change in Control, Securities shall be purchased by the Company, at the option of the Holder thereof, at a purchase price specified in paragraph 7 of the Securities (the "Change in Control Purchase Price"), as of the date that is no later than 35 Business Days after the occurrence of the Change in Control but in no event prior to the date on which such Change in Control occurs (the "Change in Control Purchase Date"), subject to satisfaction by or on behalf of the Holder of the requirements set forth in Section 3.09(c).

A "Change in Control" shall be deemed to have occurred at such time as either of the following events shall occur:

(1) any person, including its respective Affiliates and associates, other than the Company, its Subsidiaries or any employee benefits plan of the Company or its Subsidiaries, files a Schedule 13D or Schedule TO (or any successor schedule, form or report) pursuant to the Exchange Act, disclosing that such person has become the beneficial owner of 50% or more of the voting power of the Common Stock then outstanding or other capital stock into which the Common Stock is reclassified or changed; provided, however, that a person shall not be deemed beneficial owner of, or to own beneficially, (A) any securities tendered pursuant to a tender or exchange offer made by or on behalf of such person or any of such person's Affiliates until such tendered securities are accepted for purchase or exchange thereunder, or (B) any securities if such beneficial ownership (1) arises solely as a result of a revocable proxy delivered in response to a proxy or consent solicitation made pursuant to the applicable rules and regulations under the Exchange Act, and (2) is not also then reportable on Schedule 13D (or any successor schedule) under the Exchange Act; or

(2) the Company consolidates with or merges with or into another person, or sells, conveys, transfers or leases all or substantially all of its properties and assets to any person or any person consolidates with or merges with or into the

30

Company, and the outstanding Voting Stock of the Company is reclassified into, converted for or converted into the right to receive any cash, securities or other property, provided that none of these circumstances will be a change in control if the persons that beneficially own the Voting Stock of the Company immediately prior to the transaction own, directly or indirectly, shares with a majority of the total voting power of all outstanding Voting Stock of the surviving or transferee person that are entitled to vote generally in the election of that person's board of directors, managers or trustees immediately after the transaction.

For purposes of defining a change in control:

(x) the term "person" and the term "group" have the meanings given by Section 13(d) and 14(d) of the Exchange Act or any successor provisions;

(y) the term "group" includes 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 or any successor provision; and

(z) the term "beneficial owner" is determined in accordance with Rules 13d-3 and 13d-5 under the Exchange Act or any successor provisions, except that a person will be deemed to have beneficial ownership of all shares that person has the right to acquire irrespective of whether that right is exercisable immediately or only after the passage of time.

(b) Within 15 Business Days after the occurrence of a Change in Control, the Company shall mail a written notice of Change in Control by first-class mail to the Trustee and to each Holder (and to beneficial owners as required by applicable law). The notice shall include a form of Change in Control Purchase Notice to be completed by the Securityholder and shall state:

(1) briefly, the events causing a Change in Control and the date of such Change in Control;

(2) the date by which the Change in Control Purchase Notice pursuant to this Section 3.09 must be given;

(3) the Change in Control Purchase Date;

(4) the Change in Control Purchase Price and, to the extent known at the time of such notice, the amount of contingent interest, if any, that will be accrued and payable with respect to the Securities as of the Change in Control Purchase Date;

(5) the name and address of the Paying Agent and the Conversion Agent;

(6) the Conversion Rate and any adjustments thereto;

(7) that Securities as to which a Change in Control Purchase Notice has been given may be converted pursuant to Article 10 hereof only if the Change in

31

Control Purchase Notice has been withdrawn in accordance with the terms of this Indenture;

(8) that Securities must be surrendered to the Paying Agent to collect payment of the Change in Control Purchase Price and contingent interest, if any;

(9) that the Change in Control Purchase Price for any Security as to which a Change in Control Purchase Notice has been duly given and not withdrawn, together with any accrued contingent interest payable with respect thereto, will be paid promptly following the later of the Change in Control Purchase Date and the time of surrender of such Security as described in (8);

(10) briefly, the procedures the Holder must follow to exercise rights under this Section 3.09;

(11) briefly, the conversion rights of the Securities;

(12) the procedures for withdrawing a Change in Control Purchase Notice;

(13) that, unless the Company defaults in making payment of such Change in Control Purchase Price and contingent interest, if any, Original Issue Discount and contingent interest, if any, on Securities surrendered for purchase will cease to accrue on and after the Change in Control Purchase Date; and

(14) the CUSIP number of the Securities.

(c) A Holder may exercise its rights specified in Section 3.09(a) upon delivery of a written notice of purchase (a "Change in Control Purchase Notice") to the Paying Agent at any time prior to the close of business on the Change in Control Purchase Date, stating:

(1) the certificate number of the Security which the Holder will deliver to be purchased;

(2) the portion of the Principal Amount at Maturity of the Security which the Holder will deliver to be purchased, which portion must be $1,000 or an integral multiple thereof; and

(3) that such Security shall be purchased pursuant to the terms and conditions specified in paragraph 7 of the Securities.

The delivery of such Security to the Paying Agent prior to, on or after the Change in Control Purchase Date (together with all necessary endorsements) at the offices of the Paying Agent shall be a condition to the receipt by the Holder of the Change in Control Purchase Price therefor; provided, however, that such Change in Control Purchase Price shall be so paid pursuant to this Section 3.09 only if the Security so delivered to the Paying Agent shall conform in all respects to the description thereof set forth in the related Change in Control Purchase Notice.

32

The Company shall purchase from the Holder thereof, pursuant to this Section 3.09, a portion of a Security if the Principal Amount at Maturity of such portion is $1,000 or an integral multiple of $1,000. Provisions of this Indenture that apply to the purchase of all of a Security also apply to the purchase of such portion of such Security.

Any purchase by the Company contemplated pursuant to the provisions of this Section 3.09 shall be consummated by the delivery of the consideration to be received by the Holder (together with accrued and unpaid contingent interest, if any) promptly following the later of the Change in Control Purchase Date and the time of delivery of the Security to the Paying Agent in accordance with this Section 3.09.

Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Change in Control Purchase Notice contemplated by this Section 3.09(c) shall have the right to withdraw such Change in Control Purchase Notice at any time prior to the close of business on the Change in Control Purchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 3.10.

The Paying Agent shall promptly notify the Company of the receipt by it of any Change in Control Purchase Notice or written withdrawal thereof.

The Company shall not be required to comply with this Section 3.09 if a third party mails a written notice of Change in Control in the manner, at the times and otherwise in compliance with this Section 3.09 and repurchases all Securities for which a Change in Control Purchase Notice shall be delivered and not withdrawn.

SECTION 3.10. Effect of Purchase Notice or Change in Control Purchase Notice.

Upon receipt by the Paying Agent of the Purchase Notice or Change in Control Purchase Notice specified in Section 3.08(a) or Section 3.09(c), as applicable, the Holder of the Security in respect of which such Purchase Notice or Change in Control Purchase Notice, as the case may be, was given shall (unless such Purchase Notice or Change in Control Purchase Notice is withdrawn as specified in the following two paragraphs) thereafter be entitled to receive solely the Purchase Price or Change in Control Purchase Price, as the case may be, and any accrued and unpaid contingent interest, with respect to such Security. Such Purchase Price or Change in Control Purchase Price and contingent interest, if any, shall be paid to such Holder, subject to receipt of funds and/or securities by the Paying Agent, promptly following the later of (x) the Purchase Date or the Change in Control Purchase Date, as the case may be, with respect to such Security (provided the conditions in Section 3.08(a) or
Section 3.09(c), as applicable, have been satisfied) and (y) the time of delivery of such Security to the Paying Agent by the Holder thereof in the manner required by Section 3.08(a) or Section 3.09(c), as applicable. Securities in respect of which a Purchase Notice or Change in Control Purchase Notice, as the case may be, has been given by the Holder thereof may not be converted pursuant to Article 10 hereof on or after the date of the delivery of such Purchase Notice or Change in Control Purchase Notice, as the case may be, unless such Purchase Notice or Change in Control Purchase Notice, as the case may be, has first been validly withdrawn as specified in the following two paragraphs.

33

A Purchase Notice or Change in Control Purchase Notice, as the case may be, may be withdrawn by means of a written notice of withdrawal delivered to the office of the Paying Agent in accordance with the Purchase Notice or Change in Control Purchase Notice, as the case may be, at any time prior to the close of business on the Purchase Date or the Change in Control Purchase Date, as the case may be, specifying:

(1) the certificate number of the Security in respect of which such notice of withdrawal is being submitted,

(2) the Principal Amount at Maturity of the Security with respect to which such notice of withdrawal is being submitted, and

(3) the Principal Amount at Maturity, if any, of such Security which remains subject to the original Purchase Notice or Change in Control Purchase Notice, as the case may be, and which has been or will be delivered for purchase by the Company.

A written notice of withdrawal of a Purchase Notice may be in the form set forth in the preceding paragraph or may be in the form of (i) a conditional withdrawal contained in a Purchase Notice pursuant to the terms of
Section 3.08(a)(1)(D) or (ii) a conditional withdrawal containing the information set forth in Section 3.08(a)(1)(D) and the preceding paragraph and contained in a written notice of withdrawal delivered to the Paying Agent as set forth in the preceding paragraph.

There shall be no purchase of any Securities pursuant to
Section 3.08 (other than through the issuance of Common Stock in payment of the Purchase Price, including cash in lieu of fractional shares) or 3.09 if there has occurred (prior to, on or after, as the case may be, the giving, by the Holders of such Securities, of the required Purchase Notice or Change in Control Purchase Notice, as the case may be) and is continuing an Event of Default (other than a default in the payment of the Purchase Price or Change in Control Purchase Price, as the case may be, and any accrued and unpaid contingent interest with respect to such Securities). The Paying Agent will promptly return to the respective Holders thereof any Securities (x) with respect to which a Purchase Notice or Change in Control Purchase Notice, as the case may be, has been withdrawn in compliance with this Indenture, or (y) held by it during the continuance of an Event of Default (other than a default in the payment of the Purchase Price or Change in Control Purchase Price, as the case may be, and any accrued and unpaid contingent interest with respect to such Securities) in which case, upon such return, the Purchase Notice or Change in Control Purchase Notice with respect thereto shall be deemed to have been withdrawn.

SECTION 3.11. Deposit of Purchase Price or Change in Control Purchase Price.

Prior to 10:00 a.m. (local time in The City of New York) on the Business Day following the Purchase Date or the Change in Control Purchase Date, as the case may be, the Company shall deposit with the Trustee or with the Paying Agent (or, if the Company or a Subsidiary or an Affiliate of either of them is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 2.04) an amount of money (in immediately available funds if

34

deposited on such Business Day) or Common Stock, if permitted hereunder, sufficient to pay the aggregate Purchase Price or Change in Control Purchase Price, as the case may be, of, and any accrued and unpaid contingent interest with respect to, all the Securities or portions thereof which are to be purchased as of the Purchase Date or Change in Control Purchase Date, as the case may be.

SECTION 3.12. Securities Purchased in Part.

Any Security which is to be purchased only in part shall be surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder's attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security, without service charge, a new Security or Securities, of any authorized denomination as requested by such Holder in aggregate Principal Amount at Maturity equal to, and in exchange for, the portion of the Principal Amount at Maturity of the Security so surrendered which is not purchased.

SECTION 3.13. Covenant to Comply With Securities Laws Upon Purchase of Securities.

In connection with any offer to purchase or purchase of Securities under Section 3.08 or 3.09 hereof (provided that such offer or purchase constitutes an "issuer tender offer" for purposes of Rule 13e-4 (which term, as used herein, includes any successor provision thereto) under the Exchange Act at the time of such offer or purchase), the Company shall, to the extent required by law, (i) comply with Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act which may then apply, (ii) file the related Schedule TO (or any other required schedule) under the Exchange Act, and
(iii) otherwise comply with all Federal and state securities laws so as to permit the rights and obligations under Sections 3.08 and 3.09 to be exercised in the time and in the manner specified in Sections 3.08 and 3.09.

SECTION 3.14. Repayment to the Company.

The Trustee and the Paying Agent shall return to the Company any cash or shares of Common Stock that remain unclaimed as provided in paragraph 15 of the Securities, together with interest or dividends, if any, thereon (subject to the provisions of Section 7.01(f)), held by them for the payment of the Purchase Price or Change in Control Purchase Price, as the case may be, or contingent interest, if any; provided, however, that to the extent that the aggregate amount of cash or shares of Common Stock deposited by the Company pursuant to Section 3.11 exceeds the aggregate Purchase Price or Change in Control Purchase Price, as the case may be, of, and the accrued and unpaid contingent interest with respect to, the Securities or portions thereof which the Company is obligated to purchase as of the Purchase Date or Change in Control Purchase Date, as the case may be, whether as a result of withdrawal or otherwise, then promptly after the Business Day following the Purchase Date or Change in Control Purchase Date, as the case may be, the Trustee shall return any such excess to the Company together with interest or dividends, if any, thereon (subject to the provisions of Section 7.01(f)).

Principal Amount at Maturity, Issue Price plus accrued Original Issue Discount, Redemption Price, Purchase Price, Change in Control Purchase Price, and contingent interest, if any, shall be considered paid on the applicable date due if on such date (or, in the case of a Purchase Price or Change in Control Purchase Price, on the Business Day following the applicable Purchase Date or Change in Control Purchase Date, as the case may be) the Trustee or the Paying Agent holds, in accordance with this Indenture, money or securities, if permitted hereunder, sufficient to pay all such amounts then due.

The Company shall, to the extent permitted by law, pay interest on overdue amounts at the rate per annum set forth in paragraph 1 of the Securities, compounded semiannually, which interest shall accrue from the date such overdue amount was originally due to the date payment of such amount, including interest thereon, has been made or duly provided for. All such interest shall be payable on demand. The accrual of such interest on overdue amounts shall be in lieu of, and not in addition to, the continued accrual of Original Issue Discount.

SECTION 4.02. SEC and Other Reports.

If requested by the Trustee, the Company shall deliver to the Trustee, within 15 days after it files such annual and quarterly reports, information, documents and other reports with the SEC, copies of its annual report and of the information, documents and other reports (or copies of such portions of any of the foregoing as the SEC may by rules and regulations prescribe) which the Company is required to file with the SEC pursuant to
Section 13 or 15(d) of the Exchange Act. In the event the Company is at any time no longer subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, it shall continue to provide the Trustee with reports containing substantially the same information as would have been required to be filed with the SEC had the Company continued to have been subject to such reporting requirements. In such event, such reports shall be provided at the times the Company would have been required to provide reports had it continued to have been subject to such reporting requirements. The Company also shall comply with the other provisions of TIA Section 314(a). Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee's receipt of the same shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company's compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers' Certificates).

36

SECTION 4.03. Compliance Certificate.

The Company shall deliver to the Trustee within 120 days after the end of each fiscal year of the Company (beginning with the fiscal year ending on December 31, 2003) an Officers' Certificate, stating whether or not to the knowledge of the signers thereof the Company is in default in the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and if the Company shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge.

The Company shall give prompt written notice to the Trustee of the location, and of any change in the location, of any such office or agency (other than a change in the location of the office of the Trustee). If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the address of the Trustee set forth in Section 12.02.

The Company may also from time to time designate one or more other offices or agencies where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such designations.

At any time when the Company is not subject to Section 13 or 15(d) of the Exchange Act, upon the request of a Holder or any beneficial holder of Securities or shares of Common Stock that are restricted securities issued upon conversion thereof, the Company will promptly furnish or cause to be furnished Rule 144A Information (as defined below) to such Holder or any beneficial holder of Securities or holder of shares of Common Stock issued upon conversion of Securities, or to a prospective purchaser of any such security designated by any such holder, as the case may be, to the extent required to permit compliance by such Holder or holder with Rule 144A under the Securities Act in connection with the resale of any such security. "Rule 144A Information" shall be such information as is specified pursuant to Rule 144A(d)(4) under the Securities Act.

37

SECTION 4.07. Calculation of Tax Original Issue Discount.

The Company agrees, and each Holder and any beneficial owner of a Security by its purchase thereof shall be deemed to agree, to treat, for United States federal income tax purposes, the Securities as debt instruments that are subject to Treasury Regulation Section 1.1275-4(b). For United States federal income tax purposes, the Company agrees, and each Holder and any beneficial owner of a Security by its purchase thereof shall be deemed to agree, to treat the fair market value of the Common Stock received upon the conversion of a Security, or upon the Holder's or beneficial owner's exercise of a put right where the Company elects to pay in Common Stock, as a contingent payment for purposes of Treasury Regulation Section 1.1275-4(b) and to accrue interest with respect to outstanding Securities as original issue discount for United States federal income tax purposes ("Tax OID") according to the "noncontingent bond method," set forth in Section 1.1275-4(b) of the Treasury Regulations, using the comparable yield set forth in Annex C to this Indenture compounded semiannually and the projected payment schedule attached as Annex C to this Indenture.

The Company acknowledges and agrees, and each Holder and any beneficial owner of a Security by its purchase thereof shall be deemed to acknowledge and agree, that (i) the comparable yield means the annual yield the Company would pay, as of the Issue Date, on a noncontingent, nonconvertible, fixed-rate debt security with terms and conditions otherwise comparable to those of the Securities, (ii) the schedule of projected payments is determined on the basis of an assumption of linear growth of the stock price and a constant dividend yield and is not determined for any purpose other than for the determination of interest accruals and adjustments thereof in respect of the Securities for United States federal income tax purposes and (iii) the comparable yield and the schedule of projected payments do not constitute a projection or representation regarding the amounts payable on the Securities.

(3) default in the performance, or breach, of any covenant or warranty of the Company in this Indenture (other than a covenant or warranty a default in whose performance or whose breach is elsewhere in this Section specifically dealt with), and continuance of such default or breach for a period of 90 days after there has been given by registered or certified mail, to the Company by the Trustee, or to the Company and the Trustee by the Holders of at least 25% in Principal Amount at Maturity of the outstanding Securities, a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a "Notice of Default" hereunder, or

(4) a default under any Indebtedness for money borrowed by the Company or any Subsidiary or under any Mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any Subsidiary (including this Indenture), whether such Indebtedness now exists or shall hereafter be created, which default shall have resulted in such Indebtedness in an outstanding principal amount in excess of $20 million becoming or being declared due and payable prior to the date on which it would otherwise have become due and payable, without such acceleration having been rescinded or annulled, or such Indebtedness having been discharged, within a period of 10 days after there shall have been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in Principal Amount at Maturity of the outstanding Securities a written notice specifying such default and requiring the Company to cause such acceleration to be rescinded or annulled or cause such Indebtedness to be discharged and stating that such notice is a "Notice of Default" hereunder; or

(5) the entry by a court having jurisdiction in the premises of (A) a decree or order for relief in respect of the Company in an involuntary case or proceeding under any applicable Federal or state bankruptcy, insolvency, reorganization or other similar law or (B) a decree or order adjudging the Company a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Company under any applicable Federal or State law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or of any substantial part of its property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order for relief or any such other decree or order unstayed and in effect for a period of 90 consecutive days; or

(6) the commencement by the Company of a voluntary case or proceeding under any applicable Federal or state bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by it to the entry of a decree or order for relief in respect of the Company in an involuntary case or proceeding under any applicable Federal or state bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against it, or the filing by it of a petition or answer or consent seeking reorganization or relief under any applicable Federal or State law, or the consent by it to the filing of such petition or to the appointment of or taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or

40

similar official of the Company or of any substantial part of it in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by the Company in furtherance of any such action.

A Default under clause (3) or clause (4) above is not an Event of Default until the Trustee notifies the Company, or the Holders of at least 25% in aggregate Principal Amount at Maturity of the Securities at the time outstanding notify the Company and the Trustee, of the Default and the Company does not cure such Default (and such Default is not waived) within the time specified in clause (3) or clause (4) above after actual receipt of such notice. Any such notice must specify the Default, demand that it be remedied and state that such notice is a "Notice of Default".

The Company shall deliver to the Trustee, within 30 days after it becomes aware of the occurrence thereof, written notice of any event which with the giving of notice or the lapse of time, or both, would become an Event of Default under clause (3) or clause (4) above, its status and what action the Company is taking or proposes to take with respect thereto.

SECTION 6.02. Acceleration.

If an Event of Default (other than an Event of Default specified in Section 6.01(5) or (6) in respect of the Company) occurs and is continuing, the Trustee by Notice to the Company, or the Holders of at least 25% in aggregate Principal Amount at Maturity of the Securities at the time outstanding by notice to the Company and the Trustee, may declare the Issue Price plus accrued Original Issue Discount through the date of declaration, and any accrued and unpaid contingent interest through the date of such declaration, on all the Securities to be immediately due and payable. Upon such a declaration, such Issue Price plus accrued Original Issue Discount, and such accrued and unpaid contingent interest, if any, shall be due and payable immediately. If an Event of Default specified in Section 6.01(5) or (6) in respect of the Company occurs and is continuing, the Issue Price plus accrued Original Issue Discount plus any accrued and unpaid contingent interest, on all the Securities shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Securityholders. The Holders of a majority in aggregate Principal Amount at Maturity of the Securities at the time outstanding, by notice to the Trustee (and without notice to any other Securityholder) may rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of the Issue Price plus accrued Original Issue Discount plus accrued and unpaid contingent interest that have become due solely as a result of acceleration and if all amounts due to the Trustee under Section 7.07 have been paid. No such rescission shall affect any subsequent Default or impair any right consequent thereto.

SECTION 6.03. Other Remedies.

If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of the Issue Price plus accrued Original Issue Discount plus any accrued and unpaid contingent interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture.

41

The Trustee may maintain a proceeding even if the Trustee does not possess any of the Securities or does not produce any of the Securities in the proceeding. A delay or omission by the Trustee or any Securityholder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of, or acquiescence in, the Event of Default. Except as set forth in Section 2.07 hereof, no remedy is exclusive of any other remedy. All available remedies are cumulative.

SECTION 6.04. Waiver of Past Defaults.

Subject to Section 6.02, the Holders of a majority in aggregate Principal Amount at Maturity of the Securities at the time outstanding, by notice to the Trustee (and without notice to any other Securityholder), may waive an existing Default and its consequences except (1) an Event of Default described in Section 6.01(1) or (2), (2) a Default in respect of a provision that under Section 9.02 cannot be amended without the consent of each Securityholder affected or (3) a Default which constitutes a failure to convert any Security in accordance with the terms of Article 10. When a Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or impair any consequent right. This Section 6.04 shall be in lieu of Section 316(a)1(A) of the TIA and such Section 316(a)1(A) is hereby expressly excluded from this Indenture, as permitted by the TIA.

SECTION 6.05. Control by Majority.

The Holders of a majority in aggregate Principal Amount at Maturity of the Securities at the time outstanding may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines in good faith is unduly prejudicial to the rights of other Securityholders or could, in reasonable likelihood, impose personal liability upon the Trustee unless the Trustee is offered indemnity satisfactory to it. This Section 6.05 shall be in lieu of Section 316(a)1(B) of the TIA and such Section 316(a)1(B) is hereby expressly excluded from this Indenture, as permitted by the TIA.

SECTION 6.06. Limitation on Suits.

A Securityholder may not pursue any remedy with respect to this Indenture or the Securities unless:

(1) the Holder gives to the Trustee written notice stating that an Event of Default is continuing;

(2) the Holders of at least 25% in aggregate Principal Amount at Maturity of the Securities at the time outstanding make a written request to the Trustee to pursue the remedy;

(3) such Holder or Holders offer to the Trustee security or indemnity satisfactory to the Trustee against any loss, liability or expense;

42

(4) the Trustee does not comply with the request within 60 days after receipt of such notice, request and offer of security or indemnity; and

(5) the Holders of a majority in aggregate Principal Amount at Maturity of the Securities at the time outstanding do not give the Trustee a direction inconsistent with the request during such 60-day period.

A Securityholder may not use this Indenture to prejudice the rights of any other Securityholder or to obtain a preference or priority over any other Securityholder.

SECTION 6.07. Rights of Holders to Receive Payment.

Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of the Principal Amount at Maturity, Issue Price plus accrued Original Issue Discount, Redemption Price, Purchase Price, Change in Control Purchase Price, and contingent interest, if any, in respect of the Securities held by such Holder, on or after the respective due dates expressed in the Securities or any Redemption Date, and to convert the Securities in accordance with Article 10, or to bring suit for the enforcement of any such payment on or after such respective dates or the right to convert, shall not be impaired or affected adversely without the consent of such Holder.

SECTION 6.08. Collection Suit by Trustee.

If an Event of Default described in Section 6.01(1) or (2) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount owing with respect to the Securities and the amounts provided for in Section 7.07.

SECTION 6.09. Trustee May File Proofs of Claim.

In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the Principal Amount at Maturity, Issue Price plus accrued Original Issue Discount, Redemption Price, Purchase Price, Change in Control Purchase Price, and contingent interest, if any, in respect of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of any such amount) shall be entitled and empowered, by intervention in such proceeding or otherwise,

(a) to file and prove a claim for the whole amount of the Principal Amount at Maturity, Issue Price plus accrued Original Issue Discount, Redemption Price, Purchase Price, Change in Control Purchase Price as the case may be, or contingent interest, if any, and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel or any other amounts due the Trustee under Section 7.07) and of the Holders allowed in such judicial proceeding, and

43

(b) to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07.

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

SECTION 6.10. Priorities.

If the Trustee collects any money pursuant to this Article 6, it shall pay out the money in the following order:

FIRST: to the Trustee for amounts due under Section 7.07;

SECOND: to Securityholders for amounts due and unpaid on the Securities for the Principal Amount at Maturity, Issue Price plus accrued Original Issue Discount, Redemption Price, Purchase Price, Change in Control Purchase Price, as the case may be, and contingent interest, if any, ratably, without preference or priority of any kind, according to such amounts due and payable on the Securities; and

THIRD: the balance, if any, to the Company.

The Trustee may fix a record date and payment date for any payment to Securityholders pursuant to this Section 6.10. At least 15 days before such record date, the Trustee shall mail to each Securityholder and the Company a notice that states the record date, the payment date and the amount to be paid.

SECTION 6.11. Undertaking for Costs.

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit (other than the Trustee) of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys' fees and expenses, against any party litigant in the suit (other than the Trustee), having due regard to the merits and good faith of the claims or defenses made by the party litigant. This
Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of more than 10% in aggregate Principal Amount at Maturity of the Securities at the time outstanding. This
Section 6.11 shall be in lieu of

44

Section 315(e) of the TIA and such Section 315(e) is hereby expressly excluded from this Indenture, as permitted by the TIA.

SECTION 6.12. Waiver of Stay, Extension or Usury Laws.

The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury or other law wherever enacted, now or at any time hereafter in force, which would prohibit or forgive the Company from paying all or any portion of the Principal Amount at Maturity, Issue Price plus accrued Original Issue Discount, Redemption Price, Purchase Price, Change in Control Purchase Price, as the case may be, and contingent interest, if any, in respect of Securities, or any interest on such amounts, as contemplated herein, or which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

ARTICLE 7

TRUSTEE

SECTION 7.01. Duties of Trustee.

(a) If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise as a prudent person would exercise or use under the circumstances in the conduct of such person's own affairs.

The Trustee (acting in any capacity hereunder) shall be under no liability for interest on any money received by it hereunder unless otherwise agreed in writing with the Company.

SECTION 7.02. Rights of Trustee.

Subject to its duties and responsibilities under the provisions of Section 7.01, and, except as expressly excluded from this Indenture pursuant to said Section 7.01, subject also to its duties and responsibilities under the TIA:

(a) the Trustee may conclusively rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties;

(b) whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, conclusively rely upon an Officers' Certificate;

(c) the Trustee and the Bid Solicitation Agent may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder;

47

SECTION 7.03. Individual Rights of Trustee.

The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent, Registrar, Conversion Agent or co-registrar may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11.

SECTION 7.04. Trustee's Disclaimer.

The Trustee makes no representation as to the validity or adequacy of this Indenture or the Securities, it shall not be accountable for the Company's use or application of the proceeds from the Securities, it shall not be responsible for any statement in the registration statement for the Securities under the Securities Act or in the Indenture or the Securities (other than its certificate of authentication), or the determination as to which beneficial owners are entitled to receive any notices hereunder.

SECTION 7.05. Notice of Defaults.

If a Default occurs and if it is known to the Trustee, the Trustee shall give to each Securityholder notice of the Default within 90 days after the Trustee gains knowledge of the Default unless such Default shall have been cured or waived before the giving of such notice. Except in the case of a Default described in Section 6.01(1) or (2), the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of Securityholders. The second sentence of this Section 7.05 shall be in lieu of the proviso to
Section 315(b) of the TIA and such proviso is hereby expressly excluded from this Indenture, as permitted by the TIA. The Trustee shall not be deemed to have knowledge of a Default unless a Responsible Officer of the Trustee has received written notice of such Default in the manner described in Section 7.02(i).

SECTION 7.06. Reports by Trustee to Holders.

Within 60 days after each May15 beginning with the May 15 following the date of this Indenture, the Trustee shall transmit to each Securityholder requesting such, in the manner and to the extent provided in
Section 12.02, a brief report, dated as of such May 15, with respect to:

(1) any change to its eligibility under Section 7.10;

(2) the character and amount of any advances made by the Trustee, as Trustee, which remain unpaid on the date of such report, and for the reimbursement of which it claims or may claim a lien or charge, prior to that of the Securityholders, on the trust estate or on property or funds held or collected by it, if such advances so remaining unpaid aggregate more than one-half of one percent of the aggregate Principal Amount at Maturity of Securities outstanding on such date;

(3) any change to the property and funds physically in the Trustee's possession as Trustee on the date of such report; and

48

(4) any action taken by it in the performance of its duties under this Indenture which it has not previously reported and which in its opinion materially affects the Securities or the trust estate, except action in respect of a Default, notice of which has been or is to be withheld by it in accordance with
Section 7.05.

SECTION 7.07. Compensation and Indemnity.

The Company agrees:

(a) to pay to the Trustee from time to time such reasonable compensation as the Company and the Trustee shall from time to time agree in writing for all services rendered by it hereunder (which compensation shall not be limited (to the extent permitted by law) by any provision of law in regard to the compensation of a trustee of an express trust);

(b) to reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses, advances and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to its negligence or bad faith; and

(c) to indemnify the Trustee or any predecessor Trustee and their agents for, and to hold them harmless against, any loss, damage, claim, liability, cost or expense (including reasonable attorney's fees and expenses and taxes (other than taxes based upon, measured by or determined by the income of the Trustee)) reasonably incurred without negligence or bad faith on its part, arising out of or in connection with the acceptance or administration of this trust, including the reasonable costs and expenses of defending itself against any claim (whether asserted by the Company or any Holder or any other Person) or liability in connection with the acceptance, exercise or performance of any of its powers or duties hereunder.

To secure the Company's payment obligations in this Section 7.07, Holders shall have been deemed to have granted to the Trustee a lien prior to the Securities on all money or property held or collected by the Trustee, except that held in trust to pay the Principal Amount at Maturity, Issue Price plus accrued Original Issue Discount, Redemption Price, Purchase Price, Change in Control Purchase Price, contingent interest or interest, if any, as the case may be, on particular Securities.

The Company's payment obligations pursuant to this Section 7.07 shall survive the discharge of this Indenture and the resignation or removal of the Trustee. When the Trustee incurs expenses after the occurrence of a Default specified in Section 6.01(5) or (6), the expenses including the reasonable charges and expenses of its counsel, are intended to constitute expenses of administration under any Bankruptcy Law.

SECTION 7.08. Replacement of Trustee.

The Trustee may resign by so notifying the Company; provided, however, no such resignation shall be effective until a successor Trustee has accepted its appointment pursuant to this Section 7.08. The Holders of a majority in aggregate Principal Amount at Maturity of the

49

Securities at the time outstanding may remove the Trustee by so notifying the Trustee and the Company. The Company shall remove the Trustee if:

(1) the Trustee fails to comply with Section 7.10;

(2) the Trustee is adjudged bankrupt or insolvent;

(3) a receiver or public officer takes charge of the Trustee or its property; or

(4) the Trustee otherwise becomes incapable of acting.

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint, by resolution of the Board of Directors, a successor Trustee.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company satisfactory in form and substance to the retiring Trustee and the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Securityholders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in
Section 7.07.

If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of a majority in aggregate Principal Amount at Maturity of the Securities at the time outstanding may petition any court of competent jurisdiction at the expense of the Company for the appointment of a successor Trustee.

If the Trustee fails to comply with Section 7.10, any Securityholder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

The resignation or removal of a Trustee shall not diminish, impair or terminate its rights to indemnification pursuant to Section 7.07 as they relate to periods prior to such resignation or removal.

SECTION 7.09. Successor Trustee by Merger.

If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee.

SECTION 7.10. Eligibility; Disqualification.

There shall at all times be a Trustee hereunder which shall be eligible to act as Trustee and shall have a combined capital and surplus of at least $50,000,000. If such corporation publishes reports of condition at least annually, pursuant to law or to the

50

requirements of federal, state, territorial or District of Columbia supervising or examining authority, then, for the purposes of this Section 7.10, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 7.10, it shall resign immediately in the manner and with the effect hereinafter specified in this Article 7.

ARTICLE 8

DISCHARGE OF INDENTURE

SECTION 8.01. Discharge of Liability on Securities.

When (i) the Company delivers to the Trustee all outstanding Securities (other than Securities replaced pursuant to Section 2.07) for cancellation or (ii) all outstanding Securities have become due and payable and the Company deposits with the Trustee, the Paying Agent (if the Paying Agent is not the Company or any Subsidiary or any Affiliate of either of them) or the Conversion Agent cash or, if expressly permitted by the terms of the Securities or the Indenture, Common Stock or governmental obligations sufficient to pay all amounts due and owing on all outstanding Securities (other than Securities replaced pursuant to Section 2.07), and if in either case the Company pays all other sums payable hereunder by the Company, then this Indenture shall, subject to Section 7.07, cease to be of further effect. The Trustee shall join in the execution of a document prepared by the Company acknowledging satisfaction and discharge of this Indenture on demand of the Company accompanied by an Officers' Certificate and Opinion of Counsel and at the cost and expense of the Company.

SECTION 8.02. Repayment to the Company.

The Trustee and the Paying Agent shall return to the Company upon written request any money or securities held by them for the payment of any amount with respect to the Securities that remains unclaimed for two years, subject to applicable unclaimed property law. After return to the Company, Holders entitled to the money or securities must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person and the Trustee and the Paying Agent shall have no further liability to the Securityholders with respect to such money or securities for that period commencing after the return thereof.

ARTICLE 9

AMENDMENTS

SECTION 9.01. Without Consent of Holders.

The Company and the Trustee may amend this Indenture or the Securities without the consent of any Securityholder:

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

51

(2) to comply with Article 5 or Section 10.14;

(3) to secure the Company's obligations under the Securities and this Indenture;

(4) to add to the Company's covenants for the benefit of the Securityholders or to surrender any right or power conferred upon the Company;

(6) to make any change that does not adversely affect the rights of any Holder;

(7) to declare additional Purchase Dates and corresponding Purchase Prices under Section 7 of the Securities; or

(8) to make any changes necessary or appropriate for the issuance of Certificated Securities pursuant to Section 2.12(e).

Any amendment described in clause (1) above made solely to conform this Indenture to the final offering memorandum provided to investors in connection with the initial offering of the Securities by the Company will not be deemed to materially and adversely affect the interests of the Holders.

SECTION 9.02. With Consent of Holders.

With the written consent of the Holders of at least a majority in aggregate Principal Amount at Maturity of the Securities at the time outstanding, the Company and the Trustee may amend this Indenture or the Securities. However, without the consent of each Securityholder affected, an amendment to this Indenture or the Securities may not:

(1) change the provisions of this Indenture that relate to modifying or amending this Indenture;

(2) make any change in the manner of calculation or rate of accrual of, or that adversely affects the right to receive, Original Issue Discount; make any change in the manner of calculation or rate of accrual of, or that adversely affects the right to receive, contingent interest; reduce the rate of interest referred to in paragraph 1 of the Securities; or extend the time for payment of Original Issue Discount or contingent interest, if any, on any Security;

(3) reduce the Principal Amount at Maturity or the Issue Price of or change the Stated Maturity of any Security;

52

(4) reduce the Redemption Price, Purchase Price or Change in Control Purchase Price of any Security;

(8) make any change that adversely affects the right to require the Company to purchase the Securities in accordance with the terms thereof and this Indenture; or

(9) impair the right to receive payment with respect to, a Security, or right to institute suit for the enforcement of any payment with respect to, or conversion of, the Securities.

It shall not be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment, but it shall be sufficient if such consent approves the substance thereof.

After an amendment under this Section 9.02 becomes effective, the Company shall mail to each Holder a notice briefly describing the amendment. Failure to mail such notice or a defect in the notice shall not affect the validity of the amendment.

Every supplemental indenture executed pursuant to this Article shall comply with the TIA.

SECTION 9.04. Revocation and Effect of Consents, Waivers and Actions.

Until an amendment, waiver or other action by Holders becomes effective, a consent thereto by a Holder of a Security hereunder is a continuing consent by the Holder and every subsequent Holder of that Security or portion of the Security that evidences the same obligation as the consenting Holder's Security, even if notation of the consent, waiver or action is not made on the Security. However, any such Holder or subsequent Holder may revoke the consent, waiver or action as to such Holder's Security or portion of the Security if the Trustee receives the notice of revocation before the date the amendment, waiver or action becomes effective. After an amendment, waiver or action becomes effective, it shall bind every Securityholder.

SECTION 9.05. Notation on or Exchange of Securities.

SECTION 9.06. Trustee to Sign Supplemental Indentures.

The Trustee shall sign any supplemental indenture authorized pursuant to this Article 9 if the amendment contained therein does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, but need not, sign such supplemental indenture. In signing such supplemental indenture the Trustee shall receive, and (subject to the provisions of Section 7.01) shall be fully protected in relying upon, in addition to the documents required by Section 12.04, an Officers' Certificate and an Opinion of Counsel stating that such amendment is authorized or permitted by this Indenture.

SECTION 9.07. Effect of Supplemental Indentures.

Upon the execution of any supplemental indenture under this Article, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Securities theretofore or thereafter authenticated and delivered hereunder shall be bound thereby.

ARTICLE 10

CONVERSION

SECTION 10.01. Conversion Privilege.

A Holder of a Security may convert such Security into Common Stock at any time during the period stated in paragraph 9 of the Securities subject to the provisions of this Article 10. The number of shares of Common Stock issuable upon conversion of a Security per $1,000 of Principal Amount at Maturity thereof (the "Conversion Rate") shall be that set forth in paragraph 9 in the Securities, subject to adjustment as herein set forth.

A Holder may convert a portion of the Principal Amount at Maturity of a Security if the portion is $1,000 or an integral multiple of $1,000. Provisions of this Indenture that apply to conversion of all of a Security also apply to conversion of a portion of a Security.

"Average Sale Price" means the average of the Sale Prices of the Common Stock for the shorter of

(i) 30 consecutive Trading Days ending on the last full Trading Day prior to the Time of Determination with respect to the rights, warrants or options or distribution in respect of which the Average Sale Price is being calculated, or

(ii) the period (x) commencing on the date next succeeding the first public announcement of (a) the issuance of rights, warrants or options or (b) the distribution, in each case, in respect of which the Average Sale Price is being

54

calculated and (y) proceeding through the last full Trading Day prior to the Time of Determination with respect to the rights, warrants or options or distribution in respect of which the Average Sale Price is being calculated (excluding days within such period, if any, which are not Trading Days), or

(iii) the period, if any, (x) commencing on the date next succeeding the Ex-Dividend Time with respect to the next preceding (a) issuance of rights, warrants or options or (b) distribution, in each case, for which an adjustment is required by the provisions of Section 10.06(4), 10.07 or 10.08 and (y) proceeding through the last full Trading Day prior to the Time of Determination with respect to the rights, warrants or options or distribution in respect of which the Average Sale Price is being calculated (excluding days within such period, if any, which are not Trading Days).

In the event that the Ex-Dividend Time (or in the case of a subdivision, combination or reclassification, the effective date with respect thereto) with respect to a dividend, subdivision, combination or reclassification to which Section 10.06(1), (2), (3) or (5) applies occurs during the period applicable for calculating "Average Sale Price" pursuant to the definition in the preceding sentence, "Average Sale Price" shall be calculated for such period in a manner determined by the Board of Directors to reflect the impact of such dividend, subdivision, combination or reclassification on the Sale Price of the Common Stock during such period.

"Time of Determination" means the time and date of the earlier of (i) the determination of stockholders entitled to receive rights, warrants or options or a distribution, in each case, to which Section 10.07 or 10.08 applies and (ii) the time ("Ex-Dividend Time") immediately prior to the commencement of "ex-dividend" trading for such rights, warrants or options or distribution on the New York Stock Exchange or such other national or regional exchange or market on which the Common Stock is then listed or quoted.

SECTION 10.02. Conversion Procedure.

To convert a Security a Holder must satisfy the requirements in paragraph 9 of the Securities. The date on which the Holder satisfies all those requirements is the conversion date (the "Conversion Date"). The Conversion Agent shall notify the Company of the Conversion Date within one Business Day of the Conversion Date. Within two Business Days following the Conversion Date, the Company shall deliver to the Holder, through the Conversion Agent, written notice of whether such Securities shall be converted into Common Stock or paid in cash or a combination of cash and Common Stock, unless the Company shall have delivered to the Holder a notice of redemption pursuant to
Section 3.03 hereof and the Conversion Date occurs before the Redemption Date set forth in such notice. If the Company shall have notified the Holder that all of such Securities shall be converted into Common Stock, the Company shall deliver to such Holder, through the Conversion Agent, as soon as practicable but in any event no later than the fifth Business Day following the Conversion Date, a certificate for the number of full shares of Common Stock issuable upon the conversion and cash in lieu of any fractional share determined pursuant to
Section 10.03 hereof. Except as otherwise provided in this Article 10, if the Company shall have notified the Holder that all or a portion of such Securities shall be paid in cash, the Company shall deliver to the Holder surrendering such Securities the

55

amount of cash payable with respect to such Securities no later than the tenth Business Day following such Conversion Date, together with a certificate for the number of full shares of Common Stock deliverable upon the conversion and cash in lieu of any fractional shares determined pursuant to Section 10.03 hereof. Except as otherwise provided in this Article 10, the Company may not change its election with respect to the consideration to be delivered upon conversion of Securities once the Company has notified the Holder in accordance with this paragraph.

The person in whose name the certificate representing such shares is registered shall be treated as a stockholder of record on and after the Conversion Date; provided, however, that no surrender of a Security on any date when the stock transfer books of the Company shall be closed shall be effective to constitute the person or persons entitled to receive the shares of Common Stock upon such conversion as the record holder or holders of such shares of Common Stock on such date, but such surrender shall be effective to constitute the person or persons entitled to receive such shares of Common Stock as the record holder or holders thereof for all purposes at the close of business on the next succeeding day on which such stock transfer books are open; such conversion shall be at the Conversion Rate in effect on the date that such Security shall have been surrendered for conversion, as if the stock transfer books of the Company had not been closed. Upon conversion of a Security, such person shall no longer be a Holder of such Security.

No payment or adjustment will be made for dividends on, or other distributions with respect to, any Common Stock except as provided in this Article 10. On conversion of a Security, accrued Original Issue Discount attributable to the period from the Issue Date of the Security through but not including the Conversion Date, accrued Tax OID and (except as provided below) accrued contingent interest, if any, with respect to the converted Security shall not be cancelled, extinguished or forfeited, but rather shall be deemed to be paid in full to the Holder thereof through delivery of the Common Stock (together with the cash payment, if any, in lieu of fractional shares), or cash or a combination of cash and Common Stock in lieu thereof, in exchange for the Security being converted pursuant to the provisions hereof; and the fair market value of such shares of Common Stock (together with any such cash payment in lieu of fractional shares), or cash or a combination of cash and Common Stock in lieu thereof, shall be treated as delivered, to the extent thereof, first in exchange for Original Issue Discount and Tax OID accrued through the Conversion Date and accrued contingent interest, if any, and the balance, if any, of the fair market value of such Common Stock (and any such cash payment in lieu of fractional shares), or cash in lieu thereof, shall be treated as delivered in exchange for the Issue Price of the Security being converted pursuant to the provisions hereof.

The Company agrees, and each Holder and any beneficial owner of a Security by its purchase thereof shall be deemed to agree, to treat, for United States federal income tax purposes, the fair market value of the Common Stock received upon the conversion of a security (together with any cash payment in lieu of fractional shares) or cash, or a combination of cash and Common Stock as a contingent payment on the Security for purposes of Treasury Regulation
Section 1.1275-4(b).

56

If the Holder converts more than one Security at the same time, the number of shares of Common Stock issuable upon the exchange shall be based on the total Principal Amount at Maturity of the Securities converted.

If the last day on which a Security may be converted is a Legal Holiday, the Security may be surrendered on the next succeeding day that is not a Legal Holiday.

Upon surrender of a Security that is converted in part, the Company shall execute, and the Trustee shall authenticate and deliver to the Holder, a new Security in an authorized denomination equal in Principal Amount at Maturity to the unconverted portion of the Security surrendered.

The Holders' rights to convert the Securities into Common Stock are subject to the Company's right to elect instead to pay each such Holder the amount of cash set forth in the next succeeding sentence (or an equivalent amount in a combination of cash and shares of Common Stock), in lieu of delivering such Common Stock; provided, however, that if an Event of Default (other than a default in a cash payment upon conversion of the Securities) shall have occurred and be continuing, the Company shall deliver Common Stock in accordance with this Article 10, whether or not the Company has delivered a notice pursuant to Section 10.02 hereof to the effect that the Securities would be paid in cash or a combination of cash and Common Stock. The amount of cash to be paid pursuant to Section 10.02 hereof for each $1,000 of Principal Amount at Maturity of Securities (or portion thereof) upon conversion shall be equal to the average Sale Price of the Common Stock for the five consecutive trading days immediately following (i) the date of the Company's notice of its election to deliver cash upon conversion, if the Company has not given a notice of redemption pursuant to Section 3.03 hereof, or (ii) the Conversion Date, in the case of a conversion following such a notice of redemption specifying an intent to deliver cash upon conversion, in either case multiplied by the Conversion Rate (or appropriate fraction of such Conversion Rate) in effect on such Conversion Date.

SECTION 10.03. Fractional Shares.

The Company will not issue a fractional share of Common Stock upon conversion of a Security. Instead, the Company will deliver cash for the current market value of the fractional share. The current market value of a fractional share shall be determined, to the nearest 1/1,000th of a share, by multiplying the Sale Price of the Common Stock, on the last Trading Day prior to the Conversion Date, of a full share by the fractional amount and rounding the product to the nearest whole cent.

SECTION 10.04. Taxes on Conversion.

If a Holder converts a Security, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue of shares of Common Stock upon the conversion. However, the Holder shall pay any such tax which is due because the Holder requests the shares to be issued in a name other than the Holder's name. The Conversion Agent may refuse to deliver the certificates representing the Common Stock being issued in a name other than the Holder's name until the Conversion Agent receives a sum sufficient to pay any tax which will be

57

due because the shares are to be delivered in a name other than the Holder's name. Nothing herein shall preclude any tax withholding required by law or regulations.

SECTION 10.05. Company to Provide Stock.

The Company shall, prior to issuance of any Securities under this Article 10, and from time to time as may be necessary, reserve out of its authorized but unissued Common Stock a sufficient number of shares of Common Stock to permit the conversion of the Securities.

All shares of Common Stock delivered upon conversion of the Securities shall be newly issued shares or treasury shares, shall be duly and validly issued and fully paid and nonassessable and shall be free from preemptive rights and free of any lien or adverse claim.

The Company will comply with all federal and state securities laws regulating the offer and delivery of shares of Common Stock upon conversion of Securities, if any, and will list or cause to have quoted such shares of Common Stock on each national securities exchange or in the over-the-counter market or such other market on which the Common Stock is then listed or quoted.

SECTION 10.06. Adjustment for Change In Capital Stock.

If, after the Issue Date of the Securities, the Company:

(1) pays a dividend or makes a distribution on its Common Stock payable in shares of its Common Stock or shares of other Capital Stock;

(2) subdivides its shares of Common Stock;

(3) combines its shares of Common Stock; or

(4) issues by reclassification of its Common Stock any shares of its Capital Stock (other than rights, warrants or options for its Capital Stock);

then the conversion privilege and the Conversion Rate in effect immediately prior to such action shall be adjusted so that the Holder of a Security thereafter converted may receive the number of shares of Capital Stock of the Company which such Holder would have owned immediately following such action if such Holder had converted the Security immediately prior to such action.

The adjustment shall become effective immediately after the record date in the case of a dividend or distribution and immediately after the effective date in the case of a subdivision, combination or reclassification.

If after an adjustment a Holder of a Security upon conversion of such Security may receive shares of two or more classes of Capital Stock of the Company, the Conversion Rate shall thereafter be subject to adjustment upon the occurrence of an action taken with respect to any such class of Capital Stock as is contemplated by this Article 10 with respect to the Common Stock, on terms comparable to those applicable to Common Stock in this Article 10.

58

SECTION 10.07. Adjustment for Rights Issue.

If after the Issue Date of the Securities, the Company distributes any rights, warrants or options to all holders of its Common Stock entitling them, for a period expiring within 60 days after the record date for such distribution, to purchase shares of Common Stock at a price per share less than the Sale Price of the Common Stock as of the Time of Determination, the Conversion Rate shall be adjusted in accordance with the formula:

R' = R x (O + N) (O + (N x P)/M

where:

R' = the adjusted Conversion Rate.

R = the current Conversion Rate.

O = the number of shares of Common Stock outstanding on the record date for the distribution to which this Section 10.07 is being applied.

N = the number of additional shares of Common Stock offered pursuant to the distribution.

P = the offering price per share of the additional shares.

M = the Average Sale Price, minus, in the case of (i) a distribution to which Section 10.06(4) applies or (ii) a distribution to which
Section 10.08 applies, for which, in each case, (x) the record date shall occur on or before the record date for the distribution to which this Section 10.07 applies and (y) the Ex-Dividend Time shall occur on or after the date of the Time of Determination for the distribution to which this Section 10.07 applies, the fair market value (on the record date for the distribution to which this
Section 10.07 applies) of the

(1) Capital Stock of the Company distributed in respect of each share of Common Stock in such Section 10.06(4)distribution and

(2) assets of the Company or debt securities or any rights, warrants or options to purchase securities of the Company distributed in respect of each share of Common Stock in such Section 10.08 distribution.

The Board of Directors shall determine fair market values for the purposes of this Section 10.07.

The adjustment shall become effective immediately after the record date for the determination of shareholders entitled to receive the rights, warrants or options to which this Section 10.07 applies. If all of the shares of Common Stock subject to such rights, warrants or options have not been issued when such rights, warrants or options expire, then the Conversion Rate shall promptly be readjusted to the Conversion Rate which would then be in effect had the adjustment upon the issuance of such rights, warrants or options been made on the basis of the

59

actual number of shares of Common Stock issued upon the exercise of such rights, warrants or options.

No adjustment shall be made under this Section 10.07 if the application of the formula stated above in this Section 10.07 would result in a value of R' that is equal to or less than the value of R.

SECTION 10.08. Adjustment for Other Distributions.

(a) Subject to Section 10.08(b) if, after the Issue Date of the Securities, the Company distributes to all holders of its Common Stock any of its assets excluding distributions of Capital Stock or equity interests referred to in Section 10.08(b), or debt securities or any rights, warrants or options to purchase securities of the Company (including securities or cash, but excluding (x) distributions of Capital Stock referred to in Section 10.06 and distributions of rights, warrants or options referred to in Section 10.07 and
(y) cash dividends or other cash distributions that are paid out of consolidated current net earnings or earnings retained in the business as shown on the books of the Company, unless such cash dividends or other cash distributions are Extraordinary Cash Dividends), the Conversion Rate shall be adjusted, subject to the provisions of Section 10.08(c), in accordance with the formula:

R' = (R x M) M-F
where:

R' = the adjusted Conversion Rate.

R = the current Conversion Rate.

M = the Average Sale Price, minus, in the case of a distribution to which Section 10.06(4) applies, for which (i) the record date shall occur on or before the record date for the distribution to which this
Section 10.08 applies and (ii) the Ex-Dividend Time shall occur on or after the date of the Time of Determination for the distribution to which this Section 10.08(a) applies, the fair market value (on the record date for the distribution to which this Section 10.08(a) applies) of any Capital Stock of the Company distributed in respect of each share of Common Stock in such Section 10.06(4) distribution.

F = the fair market value (on the record date for the distribution to which this Section 10.08(a) applies) of the assets, securities, rights, warrants or options to be distributed in respect of each share of Common Stock in the distribution to which this Section 10.08(a) is being applied (including, in the case of cash dividends or other cash distributions giving rise to an adjustment, all such cash distributed concurrently).

The Board of Directors shall determine fair market values for the purposes of this Section 10.08(a).

The adjustment shall become effective immediately after the record date for the determination of shareholders entitled to receive the distribution to which this Section 10.08(a) applies.

60

For purposes of this Section 10.08(a), the term "Extraordinary Cash Dividend" shall mean any cash dividend with respect to the Common Stock the amount of which, together with the aggregate amount of cash dividends on the Common Stock to be aggregated with such cash dividend in accordance with the provisions of this paragraph, equals or exceeds the threshold percentage set forth in item (i) below. For purposes of item (i) below, the "Ex-Dividend Measurement Period" with respect to a cash dividend on the Common Stock shall mean the 365 consecutive day period ending on the date prior to the Ex-Dividend Time with respect to such cash dividend, and the "Relevant Cash Dividends" with respect to a cash dividend on the Common Stock shall mean the cash dividends on the Common Stock with Ex-Dividend Times occurring in the Ex-Dividend Measurement Period.

(i) If, upon the date prior to the Ex-Dividend Time with respect to a cash dividend on the Common Stock, the aggregate amount of such cash dividend together with the amounts of all Relevant Cash Dividends equals or exceeds on a per share basis the sum of (a) 5% of the Sale Price of the Common Stock on the last Trading Day preceding the date of declaration by the Board of Directors of the cash dividend or distribution with respect to which this provision is being applied, and (b) the quotient of the amount of any contingent interest paid on a Security during the Ex-Dividend Measurement Period and divided by the conversion rate in effect on the payment date of such relevant contingent interest payment date, then such cash dividend together with all Relevant Cash Dividends, shall be deemed to be an Extraordinary Cash Dividend and for purposes of applying the formula set forth above in this Section 10.08(a), the value of "F" shall be equal to (y) the aggregate amount of such cash dividend together with the amount of all Relevant Cash Dividends, minus (z) the aggregate amount of all Relevant Cash Dividends for which a prior adjustment in the Conversion Rate was previously made under this Section 10.08(a).

In making the determinations required by item (i) above, the amount of cash dividends paid on a per share basis and the amount of any Relevant Cash Dividends specified in item (i) above, shall be appropriately adjusted to reflect the occurrence during such period of any event described in
Section 10.06.

(b) If, after the Issue Date of the Securities, the Company pays a dividend or makes a distribution to all holders of its Common Stock consisting of Capital Stock of any class or series, or similar equity interests, of or relating to a Subsidiary or other business unit of the Company, then the Conversion Rate shall be adjusted in accordance with the formula:

R' = R x (1 + F/M) where:

R' = the adjusted Conversion Rate.

R = the current Conversion Rate.

M = the average of the Post-Distribution Prices of the Common Stock for the 10 Trading Days commencing on and including the fifth Trading Day after the date on which

61

"ex-dividend trading" commences for such dividend or distribution on the principal United States exchange or market which such securities are then listed or quoted (the "Ex-Dividend Date").

F = the fair market value of the securities distributed in respect of each share of Common Stock for which this Section 10.08(b) applies shall mean the number of securities distributed in respect of each share of Common Stock multiplied by the average of the Post-Distribution Prices of those securities distributed for the 10 Trading Days commencing on and including the fifth Trading Day after the Ex-Dividend Date.

"Post-Distribution Price" of Capital Stock or any similar equity interest on any date means the closing per unit sale price (or, if no closing sale price is reported, the average of the bid and ask prices or, if more than one in either case, the average of the average bid and the average ask prices) on such date for trading of such units on a "when issued" basis without due bills (or similar concept) as reported in the composite transactions for the principal United States securities exchange on which such Capital Stock or equity interest is traded or, if the Capital Stock or equity interest, as the case may be, is not listed on a United States national or regional securities exchange, as reported by the National Association of Securities Dealers Automated Quotation System or by the National Quotation Bureau Incorporated; provided that if on any date such units have not traded on a "when issued" basis, the Post-Distribution Price shall be the closing per unit sale price (or, if no closing sale price is reported, the average of the bid and ask prices or, if more than one in either case, the average of the average bid and the average ask prices) on such date for trading of such units on a "regular way" basis without due bills (or similar concept) as reported in the composite transactions for the principal United States securities exchange on which such Capital Stock or equity interest is traded or, if the Capital Stock or equity interest, as the case may be, is not listed on a United States national or regional securities exchange, as reported by the National Association of Securities Dealers Automated Quotation System or by the National Quotation Bureau Incorporated. In the absence of such quotation, the Company shall be entitled to determine the Post-Distribution Price on the basis of such quotations which reflect the post-distribution value of the Capital Stock or equity interests as it considers appropriate.

(c) In the event that, with respect to any distribution to which Section 10.08(a) or (b) would otherwise apply, the difference "M-F" is less than $1.00 or "F" is equal to or greater than "M", then the adjustment provided by Section 11.08(b) shall not be made and in lieu thereof the provisions of Section 10.14 shall apply to such distribution.

SECTION 10.09. When Adjustment May Be Deferred.

No adjustment in the Conversion Rate need be made unless the adjustment would require an increase or decrease of at least 1% in the Conversion Rate. Any adjustments that are not made shall be carried forward and taken into account in any subsequent adjustment.

All calculations under this Article 10 shall be made to the nearest cent or to the nearest 1/1,000th of a share, as the case may be (with one-half cent and 5/10,000ths of a share being rounded upward).

62

SECTION 10.10. When No Adjustment Required.

No adjustment need be made for a transaction referred to in
Section 10.06, 10.07, 10.08 or 10.14 if Securityholders are to participate in the transaction on a basis and with notice that the Board of Directors determines to be fair and appropriate in light of the basis and notice on which holders of Common Stock participate in the transaction. Such participation by Securityholders may include participation upon conversion provided that an adjustment shall be made at such time as the Securityholders are no longer entitled to participate.

No adjustment need be made for rights to purchase Common Stock pursuant to a Company plan for reinvestment of dividends or interest.

No adjustment need be made for a change in the par value or no par value of the Common Stock.

To the extent the Securities become convertible pursuant to this Article 10 into cash, no adjustment need be made thereafter as to the cash. Interest will not accrue on the cash.

SECTION 10.11. Notice of Adjustment.

Whenever the Conversion Rate is adjusted, the Company shall promptly mail to Securityholders a notice of the adjustment. The Company shall file with the Trustee and the Conversion Agent such notice and a certificate from the Company's independent public accountants briefly stating the facts requiring the adjustment and the manner of computing it. The certificate shall be conclusive evidence that the adjustment is correct. Neither the Trustee nor any Conversion Agent shall be under any duty or responsibility with respect to any such certificate except to exhibit the same to any Holder desiring inspection thereof.

SECTION 10.12. Voluntary Increase.

The Company from time to time may increase the Conversion Rate by any amount for any period of time. Whenever the Conversion Rate is increased, the Company shall mail to Securityholders and file with the Trustee and the Conversion Agent a notice of the increase. The Company shall mail the notice at least 15 days before the date the increased Conversion Rate takes effect. The notice shall state the increased Conversion Rate and the period it will be in effect.

A voluntary increase of the Conversion Rate does not change or adjust the Conversion Rate otherwise in effect for purposes of Section 10.06, 10.07 or 10.08.

SECTION 10.13. Notice of Certain Transactions.

If:

(1) the Company takes any action that would require an adjustment in the Conversion Rate pursuant to Section 10.06, 10.07 or
10.08 (unless no adjustment is to occur pursuant to Section 10.10); or

63

(2) the Company takes any action that would require a supplemental indenture pursuant to Section 10.14; or

(3) there is a liquidation or dissolution of the Company;

then the Company shall mail to Securityholders and file with the Trustee and the Conversion Agent a notice stating the proposed record date for a dividend or distribution or the proposed effective date of a subdivision, combination, reclassification, consolidation, merger, binding share exchange, transfer, liquidation or dissolution. The Company shall file and mail the notice at least 15 days before such date. Failure to file or mail the notice or any defect in it shall not affect the validity of the transaction.

In the event the Company makes a distribution pursuant to
Section 10.07 or 10.08, which, in the case of Section 10.08, has a per share value equal to more than 15% of the Sale Price of shares of its Common Stock on the day preceding the declaration date for such distribution, the Company will be required to give notice to the holders of LYONs at least 20 days prior to the Ex-Dividend Date for such distribution.

SECTION 10.14. Reorganization of Company; Special Distributions.

If the Company is a party to a transaction subject to Section
5.01 (other than a sale of all or substantially all of the assets of the Company in a transaction in which the holders of Common Stock immediately prior to such transaction do not receive securities, cash or other assets of the Company or any other person) or a merger or binding share exchange which reclassifies or changes the outstanding Common Stock of the Company, the person obligated to deliver securities, cash or other assets upon conversion of Securities shall enter into a supplemental indenture. If the issuer of securities deliverable upon conversion of Securities is an Affiliate of the successor Company, that issuer shall join in the supplemental indenture.

The supplemental indenture shall provide that the Holder of a Security may convert it into the kind and amount of securities, cash or other assets which such Holder would have received immediately after the consolidation, merger, binding share exchange or transfer if such Holder had converted the Security immediately before the effective date of the transaction, assuming (to the extent applicable) that such Holder (i) was not a constituent person or an Affiliate of a constituent person to such transaction; (ii) made no election with respect thereto; and (iii) was treated alike with the plurality of non-electing Holders. The supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practical to the adjustments provided for in this Article 10. The successor Company shall mail to Securityholders a notice briefly describing the supplemental indenture.

If this Section applies, neither Section 10.06 nor 10.07 applies.

If the Company makes a distribution to all holders of its Common Stock of any of its assets, or debt securities or any rights, warrants or options to purchase securities of the Company that, but for the provisions of
Section 10.08(c), would otherwise result in an adjustment in the Conversion Rate pursuant to the provisions of Section 10.08, then, from and after the record date for determining the holders of Common Stock entitled to receive the distribution, a Holder of a Security that converts such Security in accordance with the provisions

64

of this Indenture shall upon such conversion be entitled to receive, in addition to the shares of Common Stock into which the Security is convertible, the kind and amount of securities, cash or other assets comprising the distribution that such Holder would have received if such Holder had converted the Security immediately prior to the record date for determining the holders of Common Stock entitled to receive the distribution.

SECTION 10.15. Company Determination Final.

Any determination that the Company or the Board of Directors must make pursuant to Section 10.03, 10.06, 10.07, 10.08, 10.09, 10.10, 10.14 or 10.17 is conclusive.

SECTION 10.16. Trustee's Adjustment Disclaimer.

The Trustee has no duty to determine when an adjustment under this Article 10 should be made, how it should be made or what it should be. The Trustee has no duty to determine whether a supplemental indenture under Section 10.14 need be entered into or whether any provisions of any supplemental indenture are correct. The Trustee shall not be accountable for and makes no representation as to the validity or value of any securities or assets issued upon conversion of Securities. The Trustee shall not be responsible for the Company's failure to comply with this Article 10. Each Conversion Agent shall have the same protection under this Section 10.16 as the Trustee.

SECTION 10.17. Simultaneous Adjustments.

In the event that this Article 10 requires adjustments to the Conversion Rate under more than one of Sections 10.06(4), 10.07 or 10.08, and the record dates for the distributions giving rise to such adjustments shall occur on the same date, then such adjustments shall be made by applying, first, the provisions of Section 10.06, second, the provisions of Section 10.08 and, third, the provisions of Section 10.07.

SECTION 10.18. Successive Adjustments.

After an adjustment to the Conversion Rate under this Article 10, any subsequent event requiring an adjustment under this Article 10 shall cause an adjustment to the Conversion Rate as so adjusted.

SECTION 10.19. Rights Issued in Respect of Common Stock Issued Upon Conversion.

Each share of Common Stock issued upon conversion of Securities pursuant to this Article 10 shall be entitled to receive the appropriate number of rights ("Rights"), if any, and the certificates representing the Common Stock issued upon such conversion shall bear such legends, if any, in each case as may be provided by the terms of any shareholders rights agreement adopted by the Company, as the same may be amended form time to time (in each case, a "Rights Agreement"). Provided that such Rights Agreement requires that each share of Common Stock issued upon conversion of Securities at any time prior to the distribution of separate certificates representing the Rights be entitled to receive such Rights, then, notwithstanding anything else to the contrary in this Article 10, there shall not be any adjustment

65

to the conversion privilege or Conversion Rate as a result of the issuance of Rights, the distribution of separate certificates representing the Rights, the exercise or redemption of such Rights in accordance with any Rights Agreement, or the termination or invalidation of such Rights.

ARTICLE 11

PAYMENT OF INTEREST

SECTION 11.01. Interest Payments.

Contingent interest on any Security that is payable, and is punctually paid or duly provided for, on any applicable payment date shall be paid to the person in whose name that Security is registered at the close of business on the accrual date for such interest, as described in Paragraph 5 of the Securities, at the office or agency of the Company maintained for such purpose. Each installment of contingent interest payable in cash on any Security shall be paid in same-day funds by transfer to an account maintained by the payee located inside the United States, if the Trustee shall have received proper wire transfer instructions from such payee not later than the related accrual date or, if no such instructions have been received by check drawn on a bank in the City of New York mailed to the payee at its address set forth on the Registrar's books. In the case of a permanent Global Security, contingent interest payable on any applicable payment date will be paid to the Depositary, with respect to that portion of such permanent Global Security held for its account by Cede & Co. for the purpose of permitting such party to credit the interest received by it in respect of such permanent Global Security to the accounts of the beneficial owners thereof.

SECTION 11.02. Defaulted Interest.

Except as otherwise specified with respect to the Securities, any contingent interest on any Security that is payable, but is not punctually paid or duly provided for, within 30 days following any applicable payment date (herein called "Defaulted Interest", which term shall include any accrued and unpaid interest that has accrued on such defaulted amount in accordance with paragraph 1 of the Securities), shall forthwith cease to be payable to the registered Holder thereof on the relevant accrual date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (1) or (2) below:

(1) The Company may elect to make payment of any Defaulted Interest to the persons in whose names the Securities are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security and the date of the proposed payment (which shall not be less than 20 days after such notice is received by the Trustee), and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed

66

payment, such money when deposited to be held in trust for the benefit of the persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a special record date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment (the "Special Record Date"). The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder of Securities at his address as it appears on the list of Securityholders maintained pursuant to Section 2.05 not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the persons in whose names the Securities are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2).

(2) The Company may make payment of any Defaulted Interest on the Securities in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

SECTION 11.03. Interest Rights Preserved.

Subject to the foregoing provisions of this Article 11 and
Section 2.06, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to any contingent interest accrued and unpaid, and to accrue, which were carried by such other Security.

Liquid Yield Option(TM) Note due 2032
(Zero Coupon-Senior)

1. Interest.

This Security shall not bear interest, except as specified in this paragraph or in paragraph 5 hereof. If the Principal Amount at Maturity hereof or any portion of such Principal Amount at Maturity is not paid when due (whether upon acceleration pursuant to Section 6.02 of the Indenture, upon the date set for payment of the Redemption Price pursuant to paragraph 6 hereof, upon the date set for payment of the Purchase Price or Change in Control Purchase Price pursuant to paragraph 7 hereof or upon the Stated Maturity of this Security) or if any contingent interest due hereon is not paid when due in accordance with paragraph 5 hereof, then in each such case the overdue amount shall, to the extent permitted by law, bear interest at the rate of 0.5% per annum, compounded semiannually, which interest shall accrue from the date such overdue amount was originally due to the date payment of such amount, including interest thereon, has been made or duly provided for. All such interest shall be payable on demand. The accrual of such interest on overdue amounts shall be in lieu of, and not in addition to, the continued accrual of Original Issue Discount.

Original Issue Discount (the difference between the Issue Price and the Principal Amount at Maturity of the Security), in the period during which a Security remains outstanding, shall accrue at 0.5% per annum, on a semiannual bond equivalent basis using a 360-day year composed of twelve 30-day months, from the Issue Date of this Security.

2. Method of Payment.

Subject to the terms and conditions of the Indenture, the Company will make payments in respect of Redemption Prices, Purchase Prices, Change in Control Purchase Prices and Principal Amount at Maturity to Holders who surrender Securities to a Paying Agent to collect such payments in respect of the Securities. The Company will pay any cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. However, the Company may make such cash payments by check payable in such money.

3. Paying Agent, Conversion Agent, Registrar and Bid Solicitation Agent.

Initially, Citibank, N.A. (the "Trustee"), will act as Paying Agent, Conversion Agent, Registrar and Bid Solicitation Agent. The Company may appoint and change any Paying Agent, Conversion Agent, Registrar or co-registrar or Bid Solicitation Agent without notice, other than notice to the Trustee. The Company or any of its Subsidiaries or any of their Affiliates may act as Paying Agent, Conversion Agent, Registrar or co-registrar. None of the Company, any of its Subsidiaries or any of their Affiliates shall act as Bid Solicitation Agent.

4. Indenture.

The Company issued the Securities under an Indenture dated as of November 21, 2002 (the "Indenture"), between the Company and the Trustee. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust

A-1-5


Indenture Act of 1939, as in effect from time to time (the "TIA"). Capitalized terms used herein and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all such terms, and Securityholders are referred to the Indenture for a statement of those terms.

The Securities are general unsecured and unsubordinated obligations of the Company limited to $639,000,000 aggregate Principal Amount at Maturity (subject to Section 2.07 of the Indenture). The Indenture does not limit other indebtedness of the Company, secured or unsecured.

5. Contingent Interest.

Subject to the accrual and record date provisions specified in this Paragraph 5, the Company shall pay contingent cash interest to the Holders during any six-month period (a "Contingent Interest Period") from November 22 to May 21 and from May 22 to November 21, commencing on or after November 22, 2007, if the average LYON Market Price for the Applicable Five Trading Day Period with respect to such Contingent Interest Period equals 130% or more of the sum of the Issue Price of a Security and Original Issue Discount accrued thereon to the day immediately preceding the first day of the relevant Contingent Interest Period.

The amount of contingent interest payable per $1,000 Principal Amount at Maturity hereof in respect of any Quarterly Period within a Contingent Interest Period shall equal the greater of (x) Regular Cash Dividends paid by the Company per share of Common Stock during that Quarterly Period multiplied by the number of shares of Common Stock into which $1,000 Principal Amount at Maturity hereof is convertible pursuant to paragraph 9 hereof as of the accrual date for such contingent interest or (y) $0.62 multiplied by 4.7301, provided that if the Company does not pay cash dividends during a semiannual period, the Company will pay contingent interest semiannually at a rate of 0.5% of the average LYON Market Price for the Applicable Five Trading Day Period.

Contingent interest, if any, will accrue and be payable to Holders as of the record date for the related Regular Cash Dividend or, if no Regular Cash Dividend is paid by the Company during a Quarterly Period, to Holders as of the 15th day (whether or not a Business Day) preceding the last day of the relevant Contingent Interest Period. Such payments shall be paid on the payment date of the related Regular Cash Dividend or, if no Regular Cash Dividend is paid by the Company during any Quarterly Period, on the last day of the relevant Contingent Interest Period. Original Issue Discount will continue to accrue at 0.5% per annum whether or not contingent interest is paid.

"Applicable Five Trading Day Period" means, with respect to any Contingent Interest Period, the five Trading Days ending on the second Trading Day immediately preceding the first day of such Contingent Interest Period; provided, however, if the Company shall have declared a Regular Cash Dividend on its Common Stock that is payable during such Contingent Interest Period but for which the record date for determining stockholders entitled thereto precedes the first day of such Contingent Interest Period, then "Applicable Five Trading Day Period" shall mean, with respect to such Contingent Interest Period, the five Trading Days ending on the second Trading Day immediately preceding such record date.

A-1-6


"Regular Cash Dividends" means quarterly or other periodic cash dividends on the Company's Common Stock as declared by the Company's Board of Directors as part of its cash dividend payment practices and that are not designated by them as extraordinary or special or other nonrecurring dividends.

"LYON Market Price" means, as of any date of determination, the average of the secondary market bid quotations per $1,000 Principal Amount at Maturity obtained by the Bid Solicitation Agent for $10 million Principal Amount at Maturity of Securities at approximately 4:00 p.m., New York City time, on such determination date from three recognized securities dealers in The City of New York (none of which shall be an Affiliate of the Company) (which shall be J.P. Morgan Securities Inc., Goldman Sachs & Co. and Merrill Lynch, Pierce, Fenner & Smith Incorporated, unless instructed otherwise by the Company) selected by the Company; provided, however, if (a) at least three such bids are not obtained by the Bid Solicitation Agent or (b) in the Company's reasonable judgment, the bid quotations are not indicative of the secondary market value of the Securities as of such determination date, then the LYON Market Price for such determination date shall equal (i) the Conversion Rate in effect as of such determination date multiplied by (ii) the average Sale Price of the Common Stock for the five Trading Days ending on such determination date, appropriately adjusted to take into account the occurrence, during the period commencing on the first of such Trading Days during such five Trading Day period and ending on such determination date, of any event described in Section 10.06, 10.07 or 10.08 (subject to the conditions set forth in Sections 10.09 and 10.10) of the Indenture.

The term "Quarterly Period" shall mean, with respect to any Contingent Interest Period, any quarterly period within such Contingent Interest Period extending from November 22 to February 21, from February 22 to May 21, from May 22 to August 21 or from August 22 to November 21.

Upon determination that Holders will be entitled to receive contingent interest which may become payable during a Contingent Interest Period, on or prior to the first day of such Contingent Interest Period, the Company shall promptly notify the Trustee of such determination and shall issue a press release and publish such information on its web site on the World Wide Web or through such other public medium as the Company may use at that time as soon as practicable. The Company shall also notify the Trustee of the declaration of any Regular Cash Dividends and the related record and payment dates.

The determination of the amount of contingent interest, if any, and the payment thereof is the sole responsibility of the Company.

6. Redemption at the Option of the Company.

No sinking fund is provided for the Securities. The Securities are redeemable for cash as a whole, at any time, or in part from time to time at the option of the Company in accordance with the Indenture at the Redemption Prices set forth below, provided that the Securities are not redeemable prior to November 21, 2007.

A-1-8


7. Purchase by the Company at the Option of the Holder.

Subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase, at the option of the Holder, the Securities held by such Holder on the following Purchase Dates and at the following Purchase Prices per $1,000 Principal Amount at Maturity, upon delivery of a Purchase Notice containing the information set forth in the Indenture, at any time from the opening of business on the date that is 20 Business Days prior to such Purchase Date until the close of business on the Business Day immediately preceding such Purchase Date and upon delivery of the Securities to the Paying Agent by the Holder as set forth in the Indenture.

November 21, 2005                          $873.86
November 21, 2007                           882.64
November 21, 2012                           904.95
November 21, 2017                           927.83
November 21, 2022                           951.29
November 21, 2027                           975.34

The Company may, from time to time, declare additional Purchase Dates and corresponding Purchase Prices.

The Purchase Price (equal to the Issue Price plus accrued Original Issue Discount to the Purchase Date) may be paid, at the option of the Company, in cash or by the issuance and delivery of shares of Common Stock of the Company, or in any combination thereof.

At the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase the Securities held by such Holder no later than 35 Business Days after the occurrence of a Change in Control of the Company, but in no event prior to the date on which such Change in Control occurs, on or prior to November 21, 2007 for a Change in Control Purchase Price equal to the Issue Price plus accrued Original Issue Discount to the Change in Control Purchase Date, which Change in Control Purchase Price shall be paid in cash.

A third party may make the offer and purchase of the Securities in lieu of the Company in accordance with the Indenture.

In addition to the Purchase Price or Change in Control Purchase Price, as the case may be, payable with respect to all Securities or portions thereof to be purchased as of the Purchase Date or the Change in Control Purchase Date, as the case may be, the Holders of such Securities (or portions thereof) shall be entitled to receive any accrued and unpaid contingent interest with respect thereto, which shall be paid in cash promptly following the later of the Purchase Date or the Change in Control Purchase Date, as the case may be and the time of delivery of such Securities to the Paying Agent pursuant to the Indenture.

A-1-9


Holders have the right to withdraw any Purchase Notice or Change in Control Purchase Notice, as the case may be, by delivering to the Paying Agent a written notice of withdrawal in accordance with the provisions of the Indenture.

If cash (and/or securities if permitted under the Indenture) sufficient to pay the Purchase Price or Change in Control Purchase Price, as the case may be, of, together with any accrued and unpaid contingent interest with respect to, all Securities or portions thereof to be purchased as of the Purchase Date or the Change in Control Purchase Date, as the case may be, is deposited with the Paying Agent on the Business Day following the Purchase Date or the Change in Control Purchase Date, as the case may be, Original Issue Discount and any contingent interest shall cease to accrue on such Securities (or portions thereof) immediately after such Purchase Date or Change in Control Purchase Date, as the case may be, and the Holder thereof shall have no other rights as such (other than the right to receive the Purchase Price or Change in Control Purchase Price, as the case may be, and any accrued and unpaid contingent interest upon surrender of such Security).

8. Notice of Redemption.

Notice of redemption will be mailed at least 30 days but not more than 60 days before the Redemption Date to each Holder of Securities to be redeemed at the Holder's registered address. If money sufficient to pay the Redemption Price of, and accrued and unpaid contingent interest, if any, with respect to, all Securities (or portions thereof) to be redeemed on the Redemption Date is deposited with the Paying Agent prior to or on the Redemption Date, on such Redemption Date, Original Issue Discount and contingent interest, if any, shall cease to accrue on such Securities or portions thereof. Securities in denominations larger than $1,000 of Principal Amount at Maturity may be redeemed in part but only in integral multiples of $1,000 of Principal Amount at Maturity.

9. Conversion.

Subject to the provisions of this Paragraph 9, a Holder of a Security may convert it into Common Stock of the Company at any time before the close of business on November 20, 2032. If the Security is called for redemption, the Holder may convert it only until the close of business on the second Business Day immediately preceding the Redemption Date. A Security in respect of which a Holder has delivered a Purchase Notice or Change in Control Purchase Notice exercising the option of such Holder to require the Company to purchase such Security may be converted only if such notice of exercise is withdrawn in accordance with the terms of the Indenture.

The initial Conversion Rate is 4.7301 shares of Common Stock per $1,000 Principal Amount at Maturity, subject to adjustment in certain events described in the Indenture. The Company will deliver cash or a check in lieu of any fractional share of Common Stock.

(a) CONVERSION BASED ON COMMON STOCK PRICE. Subject to the provisions of this Paragraph 9, Holders may convert the Securities into Common Stock in any calendar quarter commencing after March 31, 2003, if, as of the last day of the preceding calendar quarter, the Sale Price of the Common Stock for at least 20 Trading Days in a period of 30 consecutive

A-1-10


Trading Days ending on the last Trading Day of such preceding calendar quarter is more than 130% of the accreted conversion price per share of Common Stock on the last day of such preceding calendar quarter.

The "accreted conversion price" per share of Common Stock as of any day equals the quotient of:

o the Issue Price of a Security and Accrued Original Issue Discount to that day, divided by

o the number of shares of Common Stock issuable upon conversion of $1,000 Principal Amount at Maturity of Securities on that day.

(b) CONVERSION BASED ON CREDIT RATING DOWNGRADE. Subject to the provisions of this Paragraph 9, Holders may convert the Securities into Common Stock on a Conversion Date during any period in which the credit rating assigned to the Securities by a Rating Agency is at or below the Applicable Rating. "Rating Agency" means Standard & Poor's Ratings Services, a division of The McGraw-Hill Companies Inc., and its successors ("Standard & Poor's"), or Moody's Investors Service ("Moody's"), or if neither Standard & Poor's nor Moody's are making ratings of the Securities publicly available, a nationally recognized U.S. rating agency or agencies, as the case may be, selected by the Company, which will be substituted for Standard & Poor's or Moody's, as the case may be. "Applicable Rating" means, in the case of Standard & Poor's, BBB+, or in the case of Moody's, Baa1 (or their respective equivalents under any successor ratings categories of Standard & Poor's or Moody's), or the equivalent in respect of ratings categories of any Rating Agencies substituted for Standard & Poor's or Moody's.

(c) CONVERSION BASED ON REDEMPTION. Subject to the provisions of this Paragraph 9, a Holder may convert into Common Stock a Security or portion of a Security which has been called for redemption pursuant to Paragraph 6 hereof, even if the Securities are not otherwise convertible at such time, but such Securities may be surrendered for conversion only until the close of business on the second Business Day immediately preceding the Redemption Date.

(d) CONVERSION UPON OCCURRENCE OF CERTAIN CORPORATE TRANSACTIONS. Subject to the provisions of this Paragraph 9, in the event the Company is a party to a consolidation, merger or binding share exchange or a transfer of all or substantially all assets of the Company pursuant to which the Common Stock would be converted into cash, securities or other property as set forth in
Section 10.14 of the Indenture, the Securities may be surrendered for conversion at any time from and after the date which is 15 days prior to the anticipated effective date until 15 days after the actual effective date of such transaction, and at the effective date of such transaction the right to convert a Security into Common Stock will be deemed to have changed into a right to convert it into the kind and amount of cash, securities or other assets of the Company or another person which the holder would have received if the holder had converted its Security immediately prior to the transaction.

A-1-11


A Holder's right to convert the Securities into Common Stock of the Company is also subject to the Company's right to elect to pay such Holder the amount of cash set forth in the next succeeding sentence (or an equivalent amount in a combination of cash and shares of Common Stock), in lieu of delivering all or part of such Common Stock; provided, however, that if such payment of cash is not permitted pursuant to the provisions of the Indenture, the Company shall deliver Common Stock (and cash in lieu of fractional shares of Common Stock) in accordance with the Indenture, whether or not the Company has delivered a notice pursuant to the Indenture to the effect that the Securities will be paid in cash. The amount of cash to be paid for each $1,000 Principal Amount at Maturity of Securities shall be equal to the average Sale Price of a share of Common Stock of the Company for the five consecutive Trading Days immediately following (i) the date of the Company's notice of its election to deliver cash upon conversion, if the Company has not given a notice of redemption pursuant to the Indenture, or (ii) the Conversion Date, in the case of a conversion following such a notice of redemption specifying an intent to deliver cash or a combination of cash and Common Stock upon conversion, in either case multiplied by the Conversion Rate in effect on such Conversion Date. If the Company shall elect to make such payment wholly in shares of Common Stock, then such shares shall be delivered through the Conversion Agent to Holders surrendering Securities as promptly as practicable but in any event no later than the fifth Business Day following the Conversion Date. If, however, the Company elects to make any portion of such payment in cash, then the payment, including any delivery of shares of Common Stock, shall be made to Holders surrendering Securities no later than the tenth Business Day following the Conversion Date.

The Company may not pay cash in lieu of delivering all or part of such share of Common Stock upon the conversion of any Securities pursuant to the terms of the Indenture (other than cash in lieu of fractional shares) if there has occurred (prior to, on or after, as the case may be, the Conversion Date or the date on which the Company delivers its notice specifying whether each Conversion shall be converted into shares of Common Stock or cash) and is continuing an Event of Default (other than a default in such payment on such Securities).

Accrued and unpaid contingent interest will not be paid in cash on Securities that are converted but will be paid in the manner provided in the following paragraph; provided, however that Securities surrendered for conversion during the period from the close of business on any date on which contingent interest accrues to the opening of business on the date on which such contingent interest is payable, shall be entitled to receive such contingent interest payable on such Securities on the corresponding Interest Payment Date or the date on which such contingent interest is payable and (except Securities with respect to which the Company has mailed a notice of redemption) Securities surrendered for conversion during such periods must be accompanied by payment of an amount equal to the contingent interest with respect thereto that the registered Holder is to receive.

A Holder may convert a portion of a Security if the Principal Amount at Maturity of such portion is $1,000 or an integral multiple of $1,000. No payment or adjustment will be made for dividends on the Common Stock except as provided in the Indenture. On conversion of a Security, accrued Original Issue Discount attributable to the period from the Issue Date through the Conversion Date, accrued Tax OID and (except as provided above) accrued contingent interest with respect to the converted Security shall not be cancelled, extinguished or forfeited, but rather shall be deemed to be paid in full to the Holder thereof through the delivery of the

A-1-12


Common Stock (together with the cash payment, if any, in lieu of fractional shares), or cash or a combination of cash and Common Stock in lieu thereof, in exchange for the Security being converted pursuant to the terms hereof; and the fair market value of such shares of Common Stock (together with any such cash payment in lieu of fractional shares), or cash or a combination of cash and Common Stock in lieu thereof, shall be treated as delivered, to the extent thereof, first in exchange for Original Issue Discount and Tax OID accrued through the Conversion Date and accrued contingent interest, if any, and the balance, if any, of such cash and/or the fair market value of such Common Stock (and any such cash payment in lieu of fractional shares), or cash in lieu thereof, shall be treated as delivered in exchange for the Issue Price of the Security being converted pursuant to the provisions hereof.

The Company agrees, and each Holder and any beneficial owner of a Security by its purchase thereof shall be deemed to agree, to treat, for United States federal income tax purposes, the fair market value of the Common Stock received upon the conversion of a Security (together with any cash payment in lieu of fractional shares) or cash, or a combination of cash and Common Stock as a contingent payment on the Security for purposes of Treasury Regulation Section 1.1275-4(b).

To convert a Security, a Holder must (1) complete and manually sign the conversion notice below (or complete and manually sign a facsimile of such notice) and deliver such notice to the Conversion Agent, (2) surrender the Security to the Conversion Agent, (3) furnish appropriate endorsements and transfer documents if required by the Conversion Agent, the Company or the Trustee and (4) pay any transfer or similar tax, if required.

The Conversion Rate will be adjusted for dividends or distributions on Common Stock payable in Common Stock or other Capital Stock; subdivisions, combinations or certain reclassifications of Common Stock; distributions to all holders of Common Stock of certain rights to purchase Common Stock for a period expiring within 60 days of the record date for such distribution at less than the Sale Price of the Common Stock at the Time of Determination; and distributions to such holders of assets (including shares of Capital Stock of a Subsidiary) or debt securities of the Company or certain rights to purchase securities of the Company (excluding certain cash dividends or distributions). However, no adjustment need be made if Securityholders may participate in the transaction or in certain other cases. The Company from time to time may voluntarily increase the Conversion Rate.

If the Company is a party to a consolidation, merger or binding share exchange or a transfer of all or substantially all of its assets, or upon certain distributions described in the Indenture, the right to convert a Security into Common Stock may be changed into a right to convert it into the kind and amount of securities, cash or other assets of the Company or another person which the Holder would have received if the Holder had converted its Securities immediately prior to the transaction.

10. Conversion Arrangement on Call for Redemption.

Any Securities called for redemption, unless surrendered for conversion before the close of business on the Redemption Date, may be deemed to be purchased from the Holders of such Securities at an amount not less than the Redemption Price, by one or more investment bankers

A-1-13


or other purchasers who may agree with the Company to purchase such Securities from the Holders, to convert them into Common Stock of the Company and to make payment for such Securities to the Trustee in trust for such Holders.

11. Defaulted Interest.

Except as otherwise specified with respect to the Securities, any Defaulted Interest on any Security shall forthwith cease to be payable to the registered Holder thereof on the relevant accrual date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company as provided for in Section 11.02 of the Indenture.

12. Denominations; Transfer; Exchange.

The Securities are in fully registered form, without coupons, in denominations of $1,000 of Principal Amount at Maturity and integral multiples of $1,000. A Holder may transfer or exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not register the transfer or exchange of any Securities selected for redemption (except, in the case of a Security to be redeemed in part, the portion of the Security not to be redeemed) or any Securities in respect of which a Purchase Notice or Change in Control Purchase Notice has been given and not withdrawn (except, in the case of a Security to be purchased in part, the portion of the Security not to be purchased) or any Securities for a period of 15 days before the mailing of a notice of redemption of Securities to be redeemed.

13. Persons Deemed Owners.

The registered Holder of this Security may be treated as the owner of this Security for all purposes.

14. Unclaimed Money or Securities.

The Trustee and the Paying Agent shall return to the Company upon written request any money or securities held by them for the payment of any amount with respect to the Securities that remains unclaimed for two years, subject to applicable unclaimed property laws. After return to the Company, Holders entitled to the money or securities must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person.

15. Amendment; Waiver.

Subject to certain exceptions set forth in the Indenture, (i) the Indenture or the Securities may be amended with the written consent of the Holders of at least a majority in aggregate Principal Amount at Maturity of the Securities at the time outstanding and (ii) certain Defaults may be waived with the written consent of the Holders of a majority in aggregate Principal Amount at Maturity of the Securities at the time outstanding. Subject to certain exceptions set forth in the Indenture, without the consent of any Securityholder, the Company and the Trustee may amend the Indenture or the Securities to cure any ambiguity, omission, defect or

A-1-14


inconsistency, or to comply with Article 5 or Section 10.14 of the Indenture, to secure the Company's obligations under this Security or to add to the Company's covenants for the benefit of the Securityholders or to surrender any right or power conferred, or to comply with any requirement of the SEC in connection with the qualification of the Indenture under the Trust Indenture Act of 1939 and any amendment thereof, or as necessary in connection with the registration of the Securities under the Securities Act or to make any change that does not adversely affect the rights of any Holders.

16. Defaults and Remedies.

Under the Indenture, Events of Default include (i) default in the payment of contingent interest when the same becomes due and payable, which default continues for 30 days; (ii) default in payment of the Principal Amount at Maturity, Issue Price plus accrued Original Issue Discount, Redemption Price, Purchase Price or Change in Control Purchase Price, as the case may be, in respect of the Securities when the same becomes due and payable; (iii) failure by the Company to comply with other agreements in the Indenture or the Securities, subject to notice and lapse of time; (iv) the acceleration of Debt in an amount in excess of $20,000,000 because of a default with respect to such Debt without such Debt having been discharged or such acceleration having been cured, waived, rescinded or annulled, subject to notice and lapse of time; provided, however, that if any such failure or acceleration referred to above shall cease or be cured, waived, rescinded or annulled, then the Event of Default by reason thereof shall be deemed not to have occurred; and (v) certain events of bankruptcy or insolvency. If an Event of Default occurs and is continuing, the Trustee, or the Holders of at least 25% in aggregate Principal Amount at Maturity of the Securities at the time outstanding, may declare the Issue Price plus the Original Issue Discount through the date of such declaration, and any accrued and unpaid interest (including contingent interest) if any, through the date of such declaration, on all the Securities to be due and payable immediately. Certain events of bankruptcy or insolvency are Events of Default which will result in the Issue Price plus the Original Issue Discount on the Securities, and any accrued and unpaid interest (including contingent interest) if any, through the occurrence of such event, becoming due and payable immediately upon the occurrence of such Events of Default.

Securityholders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Securities unless it receives indemnity or security reasonably satisfactory to it. Subject to certain limitations, Holders of a majority in aggregate Principal Amount at Maturity of the Securities at the time outstanding may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Securityholders notice of any continuing Default (except a Default in payment of amounts specified in clause (i) or (ii) above) if it determines that withholding notice is in their interests.

17. Trustee Dealings with the Company.

Subject to certain limitations imposed by the TIA, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.

A-1-15


18. No Recourse Against Others.

A director, officer, employee or stockholder, as such, of the Company shall not have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security, each Securityholder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities.

19. Authentication.

This Security shall not be valid until an authorized officer of the Trustee manually signs the Trustee's Certificate of Authentication on the other side of this Security.

20. Abbreviations.

Customary abbreviations may be used in the name of a Securityholder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with right of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act).

[FORM OF REVERSE SIDE OF LYON]
Liquid Yield OptionTM Note due 2032
(Zero Coupon-Senior)

1. Interest.

This Security shall not bear interest, except as specified in this paragraph or in paragraph 5 hereof. If the Principal Amount at Maturity hereof or any portion of such Principal Amount at Maturity is not paid when due (whether upon acceleration pursuant to Section 6.02 of the Indenture, upon the date set for payment of the Redemption Price pursuant to paragraph 6 hereof, upon the date set for payment of the Purchase Price or Change in Control Purchase Price pursuant to paragraph 7 hereof or upon the Stated Maturity of this Security) or if any contingent interest due hereon is not paid when due in accordance with paragraph 5 hereof, then in each such case the overdue amount shall, to the extent permitted by law, bear interest at the rate of 0.5% per annum, compounded semiannually, which interest shall accrue from the date such overdue amount was originally due to the date payment of such amount, including interest thereon, has been made or duly provided for. All such interest shall be payable on demand. The accrual of such interest on overdue amounts shall be in lieu of, and not in addition to, the continued accrual of Original Issue Discount.

Original Issue Discount (the difference between the Issue Price and the Principal Amount at Maturity of the Security), in the period during which a Security remains outstanding, shall accrue at [ ]% per annum, on a semiannual bond equivalent basis using a 360-day year composed of twelve 30-day months, from the Issue Date of this Security.

2. Method of Payment.

Subject to the terms and conditions of the Indenture, the Company will make payments in respect of Redemption Prices, Purchase Prices, Change in Control Purchase Prices and Principal Amount at Maturity to Holders who surrender Securities to a Paying Agent to collect such payments in respect of the Securities. The Company will pay any cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. However, the Company may make such cash payments by check payable in such money.

3. Paying Agent, Conversion Agent, Registrar and Bid Solicitation Agent.

Initially, Citibank, N.A. (the "Trustee"), will act as Paying Agent, Conversion Agent, Registrar and Bid Solicitation Agent. The Company may appoint and change any Paying Agent, Conversion Agent, Registrar or co-registrar or Bid Solicitation Agent without notice, other than notice to the Trustee. The Company or any of its Subsidiaries or any of their Affiliates may act as Paying Agent, Conversion Agent, Registrar or co-registrar. None of the Company, any of its Subsidiaries or any of their Affiliates shall act as Bid Solicitation Agent.

4. Indenture.

The Company issued the Securities under an Indenture dated as of November 21, 2002 (the "Indenture"), between the Company and the Trustee. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust

A-2-5


Indenture Act of 1939, as in effect from time to time (the "TIA"). Capitalized terms used herein and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all such terms, and Securityholders are referred to the Indenture for a statement of those terms.

The Securities are general unsecured and unsubordinated obligations of the Company limited to $639,000,000 aggregate Principal Amount at Maturity (subject to Section 2.07 of the Indenture). The Indenture does not limit other indebtedness of the Company, secured or unsecured.

5. Contingent Interest.

Subject to the accrual and record date provisions specified in this paragraph 5, the Company shall pay contingent cash interest to the Holders during any six-month period (a "Contingent Interest Period") from November 22 to May 21 and from May 22 to November 21, commencing on or after November 22, 2007, if the average LYON Market Price for the Applicable Five Trading Day Period with respect to such Contingent Interest Period equals 130% or more of the sum of the Issue Price of a Security and Original Issue Discount accrued thereon to the day immediately preceding the first day of the relevant Contingent Interest Period.

The amount of contingent interest payable per $1,000 Principal Amount at Maturity hereof in respect of any Quarterly Period within a Contingent Interest Period shall equal the greater of (x) Regular Cash Dividends paid by the Company per share of Common Stock during that Quarterly Period multiplied by the number of shares of Common Stock into which $1,000 Principal Amount at Maturity hereof is convertible pursuant to paragraph 9 hereof as of the accrual date for such contingent interest or (y) $0.62 multiplied by 4.7301, provided that if the Company does not pay cash dividends during a semiannual period, the Company will pay contingent interest semiannually at a rate of [0.125]% of the average LYON Market Price for the Applicable Five Trading Day Period.

Contingent interest, if any, will accrue and be payable to Holders as of the record date for the related Regular Cash Dividend or, if no Regular Cash Dividend is paid by the Company during a Quarterly Period, to Holders as of the 15th day (whether or not a Business Day) preceding the last day of the relevant Contingent Interest Period. Such payments shall be paid on the payment date of the related Regular Cash Dividend or, if no Regular Cash Dividend is paid by the Company during any Quarterly Period, on the last day of the relevant Contingent Interest Period. Original Issue Discount will continue to accrue at 1.125% per annum whether or not contingent interest is paid.

"Applicable Five Trading Day Period" means, with respect to any Contingent Interest Period, the five Trading Days ending on the second Trading Day immediately preceding the first day of such Contingent Interest Period; provided, however, if the Company shall have declared a Regular Cash Dividend on its Common Stock that is payable during such Contingent Interest Period but for which the record date for determining stockholders entitled thereto precedes the first day of such Contingent Interest Period, then "Applicable Five Trading Day Period" shall mean, with respect to such Contingent Interest Period, the five Trading Days ending on the second Trading Day immediately preceding such record date.

A-2-6


"Regular Cash Dividends" means quarterly or other periodic cash dividends on the Company's Common Stock as declared by the Company's Board of Directors as part of its cash dividend payment practices and that are not designated by them as extraordinary or special or other nonrecurring dividends.

"LYON Market Price" means, as of any date of determination, the average of the secondary market bid quotations per $1,000 Principal Amount at Maturity obtained by the Bid Solicitation Agent for $10 million Principal Amount at Maturity of Securities at approximately 4:00 p.m., New York City time, on such determination date from three recognized securities dealers in The City of New York (none of which shall be an Affiliate of the Company) (which shall be J.P. Morgan Securities Inc., Goldman Sachs & Co. and Merrill Lynch, Pierce, Fenner & Smith Incorporated, unless instructed otherwise by the Company) selected by the Company; provided, however, if (a) at least three such bids are not obtained by the Bid Solicitation Agent or (b) in the Company's reasonable judgment, the bid quotations are not indicative of the secondary market value of the Securities as of such determination date, then the LYON Market Price for such determination date shall equal (i) the Conversion Rate in effect as of such determination date multiplied by (ii) the average Sale Price of the Common Stock for the five Trading Days ending on such determination date, appropriately adjusted to take into account the occurrence, during the period commencing on the first of such Trading Days during such five Trading Day period and ending on such determination date, of any event described in Section 10.06, 10.07 or 10.08 (subject to the conditions set forth in Sections 10.09 and 10.10) of the Indenture.

The term "Quarterly Period" shall mean, with respect to any Contingent Interest Period, any quarterly period within such Contingent Interest Period extending from November 22 to February 21, from February 22 to May 21, from May 22 to August 21 or from August 22 to November 21.

Upon determination that Holders will be entitled to receive contingent interest which may become payable during a Contingent Interest Period, on or prior to the first day of such Contingent Interest Period, the Company shall promptly notify the Trustee of such determination and shall issue a press release and publish such information on its web site on the World Wide Web or through such other public medium as the Company may use at that time as soon as practicable. The Company shall also notify the Trustee of the declaration of any Regular Cash Dividends and the related record and payment dates.

The determination of the amount of contingent interest, if any, and the payment thereof is the sole responsibility of the Company.

6. Redemption at the Option of the Company.

No sinking fund is provided for the Securities. The Securities are redeemable for cash as a whole, at any time, or in part from time to time at the option of the Company in accordance with the Indenture at the Redemption Prices set forth below, provided that the Securities are not redeemable prior to November 21, 2007.

A-2-7


The table below shows Redemption Prices of a Security per $1,000 Principal Amount at Maturity on the dates shown below and at Stated Maturity, which prices reflect accrued Original Issue Discount calculated to each such date. The Redemption Price of a Security redeemed between such dates shall include an additional amount reflecting the additional Original Issue Discount accrued since the preceding date in the table and until, but not including, the Redemption Date.

  Purchase Date                   Purchase Price
-----------------                 --------------
November 21, 2005                     $873.86
November 21, 2007                      882.64

November 21, 2027                      975.34

The Company may, from time to time, declare additional Purchase Dates and corresponding Purchase Prices.

The Purchase Price (equal to the Issue Price plus accrued Original Issue Discount to the Purchase Date) may be paid, at the option of the Company, in cash or by the issuance and delivery of shares of Common Stock of the Company, or in any combination thereof.

At the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase the Securities held by such Holder no later than 35 Business Days after the occurrence of a Change in Control of the Company, but in no event prior to the date on which such Change in Control occurs, on or prior to November 21, 2007 for a Change in Control Purchase Price equal to the Issue Price plus accrued Original Issue Discount to the Change in Control Purchase Date, which Change in Control Purchase Price shall be paid in cash.

A third party may make the offer and purchase of the Securities in lieu of the Company in accordance with the Indenture.

In addition to the Purchase Price or Change in Control Purchase Price, as the case may be, payable with respect to all Securities or portions thereof to be purchased as of the Purchase Date or the Change in Control Purchase Date, as the case may be, the Holders of such Securities (or portions thereof) shall be entitled to receive any accrued and unpaid contingent interest with respect thereto, which shall be paid in cash promptly following the later of the Purchase Date or the Change in Control Purchase Date, as the case may be and the time of delivery of such Securities to the Paying Agent pursuant to the Indenture.

A-2-9


Holders have the right to withdraw any Purchase Notice or Change in Control Purchase Notice, as the case may be, by delivering to the Paying Agent a written notice of withdrawal in accordance with the provisions of the Indenture.

If cash (and/or securities if permitted under the Indenture) sufficient to pay the Purchase Price or Change in Control Purchase Price, as the case may be, of, together with any accrued and unpaid contingent interest with respect to, all Securities or portions thereof to be purchased as of the Purchase Date or the Change in Control Purchase Date, as the case may be, is deposited with the Paying Agent on the Business Day following the Purchase Date or the Change in Control Purchase Date, as the case may be, Original Issue Discount and any contingent interest shall cease to accrue on such Securities (or portions thereof) immediately after such Purchase Date or Change in Control Purchase Date, as the case may be, and the Holder thereof shall have no other rights as such (other than the right to receive the Purchase Price or Change in Control Purchase Price, as the case may be, and any accrued and unpaid contingent interest upon surrender of such Security).

8. Notice of Redemption.

Notice of redemption will be mailed at least 30 days but not more than 60 days before the Redemption Date to each Holder of Securities to be redeemed at the Holder's registered address. If money sufficient to pay the Redemption Price of, and accrued and unpaid contingent interest, if any, with respect to, all Securities (or portions thereof) to be redeemed on the Redemption Date is deposited with the Paying Agent prior to or on the Redemption Date, on such Redemption Date, Original Issue Discount and contingent interest, if any, shall cease to accrue on such Securities or portions thereof. Securities in denominations larger than $1,000 of Principal Amount at Maturity may be redeemed in part but only in integral multiples of $1,000 of Principal Amount at Maturity.

9. Conversion.

Subject to the provisions of this Paragraph 9, a Holder of a Security may convert it into Common Stock of the Company at any time before the close of business on November 20, 2032. If the Security is called for redemption, the Holder may convert it only until the close of business on the second Business Day immediately preceding the Redemption Date. A Security in respect of which a Holder has delivered a Purchase Notice or Change in Control Purchase Notice exercising the option of such Holder to require the Company to purchase such Security may be converted only if such notice of exercise is withdrawn in accordance with the terms of the Indenture.

The initial Conversion Rate is 4.7301 shares of Common Stock per $1,000 Principal Amount at Maturity, subject to adjustment in certain events described in the Indenture. The Company will deliver cash or a check in lieu of any fractional share of Common Stock.

(a) CONVERSION BASED ON COMMON STOCK PRICE. Subject to the provisions of this Paragraph 9, Holders may convert the Securities into Common Stock in any calendar quarter commencing after March 31, 2003, if, as of the last day of the preceding calendar quarter, the Sale Price of the Common Stock for at least 20 Trading Days in a period of 30 consecutive

A-2-10


Trading Days ending on the last Trading Day of such preceding calendar quarter is more than 130% of the accreted conversion price per share of Common Stock on the last day of such preceding calendar quarter.

The "accreted conversion price" per share of Common Stock as of any day equals the quotient of:

o the Issue Price of a Security and Accrued Original Issue Discount to that day, divided by

o the number of shares of Common Stock issuable upon conversion of $1,000 Principal Amount at Maturity of Securities on that day.

(b) CONVERSION BASED ON CREDIT RATING DOWNGRADE. Subject to the provisions of this Paragraph 9, Holders may convert the Securities into Common Stock on a Conversion Date during any period in which the credit rating assigned to the Securities by a Rating Agency is at or below the Applicable Rating. "Rating Agency" means Standard & Poor's Ratings Services, a division of The McGraw-Hill Companies Inc., and its successors ("Standard & Poor's"), or Moody's Investors Service ("Moody's"), or if neither Standard & Poor's nor Moody's are making ratings of the Securities publicly available, a nationally recognized U.S. rating agency or agencies, as the case may be, selected by the Company, which will be substituted for Standard & Poor's or Moody's, as the case may be. "Applicable Rating" means, in the case of Standard & Poor's, BBB+, or in the case of Moody's, Baa1 (or their respective equivalents under any successor ratings categories of Standard & Poor's or Moody's), or the equivalent in respect of ratings categories of any Rating Agencies substituted for Standard & Poor's or Moody's.

(c) CONVERSION BASED ON REDEMPTION. Subject to the provisions of this Paragraph 9, a Holder may convert into Common Stock a Security or portion of a Security which has been called for redemption pursuant to Paragraph 6 hereof, even if the Securities are not otherwise convertible at such time, but such Securities may be surrendered for conversion only until the close of business on the second Business Day immediately preceding the Redemption Date.

(d) CONVERSION UPON OCCURRENCE OF CERTAIN CORPORATE TRANSACTIONS. Subject to the provisions of this Paragraph 9, in the event the Company is a party to a consolidation, merger or binding share exchange or a transfer of all or substantially all assets of the Company pursuant to which the Common Stock would be converted into cash, securities or other property as set forth in Section 10.14 of the Indenture, the Securities may be surrendered for conversion at any time from and after the date which is 15 days prior to the anticipated effective date until 15 days after the actual effective date of such transaction, and at the effective date of such transaction the right to convert a Security into Common Stock will be deemed to have changed into a right to convert it into the kind and amount of cash, securities or other assets of the Company or another person which the holder would have received if the holder had converted its Security immediately prior to the transaction.

A-2-11


A Holder's right to convert the Securities into Common Stock of the Company is also subject to the Company's right to elect to pay such Holder the amount of cash set forth in the next succeeding sentence (or an equivalent amount in a combination of cash and shares of Common Stock), in lieu of delivering all or part of such Common Stock; provided, however, that if such payment of cash is not permitted pursuant to the provisions of the Indenture, the Company shall deliver Common Stock (and cash in lieu of fractional shares of Common Stock) in accordance with the Indenture, whether or not the Company has delivered a notice pursuant to the Indenture to the effect that the Securities will be paid in cash. The amount of cash to be paid for each $1,000 Principal Amount at Maturity of Securities shall be equal to the average Sale Price of a share of Common Stock of the Company for the five consecutive Trading Days immediately following (i) the date of the Company's notice of its election to deliver cash upon conversion, if the Company has not given a notice of redemption pursuant to the Indenture, or (ii) the Conversion Date, in the case of a conversion following such a notice of redemption specifying an intent to deliver cash or a combination of cash and Common Stock upon conversion, in either case multiplied by the Conversion Rate in effect on such Conversion Date. If the Company shall elect to make such payment wholly in shares of Common Stock, then such shares shall be delivered through the Conversion Agent to Holders surrendering Securities as promptly as practicable but in any event no later than the fifth Business Day following the Conversion Date. If, however, the Company elects to make any portion of such payment in cash, then the payment, including any delivery of shares of Common Stock, shall be made to Holders surrendering Securities no later than the tenth Business Day following the Conversion Date.

The Company may not pay cash in lieu of delivering all or part of such share of Common Stock upon the conversion of any Securities pursuant to the terms of the Indenture (other than cash in lieu of fractional shares) if there has occurred (prior to, on or after, as the case may be, the Conversion Date or the date on which the Company delivers its notice specifying whether each Conversion shall be converted into shares of Common Stock or cash) and is continuing an Event of Default (other than a default in such payment on such Securities).

Accrued and unpaid contingent interest will not be paid in cash on Securities that are converted but will be paid in the manner provided in the following paragraph; provided, however that Securities surrendered for conversion during the period from the close of business on any date on which contingent interest accrues to the opening of business on the date on which such contingent interest is payable, shall be entitled to receive such contingent interest payable on such Securities on the corresponding Interest Payment Date or the date on which such contingent interest is payable and (except Securities with respect to which the Company has mailed a notice of redemption) Securities surrendered for conversion during such periods must be accompanied by payment of an amount equal to the contingent interest with respect thereto that the registered Holder is to receive.

A Holder may convert a portion of a Security if the Principal Amount at Maturity of such portion is $1,000 or an integral multiple of $1,000. No payment or adjustment will be made for dividends on the Common Stock except as provided in the Indenture. On conversion of a Security, accrued Original Issue Discount attributable to the period from the Issue Date through the Conversion Date, accrued Tax OID and (except as provided above) accrued contingent interest with respect to the converted Security shall not be cancelled, extinguished or forfeited, but rather shall be deemed to be paid in full to the Holder thereof through the delivery of the

A-2-12


Common Stock (together with the cash payment, if any, in lieu of fractional shares), or cash or a combination of cash and Common Stock in lieu thereof, in exchange for the Security being converted pursuant to the terms hereof; and the fair market value of such shares of Common Stock (together with any such cash payment in lieu of fractional shares), or cash or a combination of cash and Common Stock in lieu thereof, shall be treated as delivered, to the extent thereof, first in exchange for Original Issue Discount and Tax OID accrued through the Conversion Date and accrued contingent interest, and the balance, if any, of such cash and/or the fair market value of such Common Stock (and any such cash payment in lieu of fractional shares), or cash in lieu thereof, shall be treated as delivered in exchange for the Issue Price of the Security being converted pursuant to the provisions hereof.

The Company agrees, and each Holder and any beneficial owner of a Security by its purchase thereof shall be deemed to agree, to treat, for United States federal income tax purposes, the fair market value of the Common Stock received upon the conversion of a Security (together with any cash payment in lieu of fractional shares) or cash, or a combination of cash and Common Stock as a contingent payment on the Security for purposes of Treasury Regulation Section 1.1275-4(b).

To convert a Security, a Holder must (1) complete and manually sign the conversion notice below (or complete and manually sign a facsimile of such notice) and deliver such notice to the Conversion Agent, (2) surrender the Security to the Conversion Agent, (3) furnish appropriate endorsements and transfer documents if required by the Conversion Agent, the Company or the Trustee and (4) pay any transfer or similar tax, if required.

The Conversion Rate will be adjusted for dividends or distributions on Common Stock payable in Common Stock or other Capital Stock; subdivisions, combinations or certain reclassifications of Common Stock; distributions to all holders of Common Stock of certain rights to purchase Common Stock for a period expiring within 60 days of the record date for such distribution at less than the Sale Price of the Common Stock at the Time of Determination; and distributions to such holders of assets (including shares of Capital Stock of a Subsidiary) or debt securities of the Company or certain rights to purchase securities of the Company (excluding certain cash dividends or distributions). However, no adjustment need be made if Securityholders may participate in the transaction or in certain other cases. The Company from time to time may voluntarily increase the Conversion Rate.

If the Company is a party to a consolidation, merger or binding share exchange or a transfer of all or substantially all of its assets, or upon certain distributions described in the Indenture, the right to convert a Security into Common Stock may be changed into a right to convert it into the kind and amount of securities, cash or other assets of the Company or another person which the Holder would have received if the Holder had converted its Securities immediately prior to the transaction.

10. Conversion Arrangement on Call for Redemption.

Any Securities called for redemption, unless surrendered for conversion before the close of business on the Redemption Date, may be deemed to be purchased from the Holders of such Securities at an amount not less than the Redemption Price, by one or more investment bankers

A-2-13


or other purchasers who may agree with the Company to purchase such Securities from the Holders, to convert them into Common Stock of the Company and to make payment for such Securities to the Trustee in trust for such Holders.

11. Defaulted Interest.

Except as otherwise specified with respect to the Securities, any Defaulted Interest on any Security shall forthwith cease to be payable to the registered Holder thereof on the relevant accrual date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company as provided for in Section 11.02 of the Indenture.

12. Denominations; Transfer; Exchange.

The Securities are in fully registered form, without coupons, in denominations of $1,000 of Principal Amount at Maturity and integral multiples of $1,000. A Holder may transfer or exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not register the transfer or exchange of any Securities selected for redemption (except, in the case of a Security to be redeemed in part, the portion of the Security not to be redeemed) or any Securities in respect of which a Purchase Notice or Change in Control Purchase Notice has been given and not withdrawn (except, in the case of a Security to be purchased in part, the portion of the Security not to be purchased) or any Securities for a period of 15 days before the mailing of a notice of redemption of Securities to be redeemed.

13. Persons Deemed Owners.

The registered Holder of this Security may be treated as the owner of this Security for all purposes.

14. Unclaimed Money or Securities.

The Trustee and the Paying Agent shall return to the Company upon written request any money or securities held by them for the payment of any amount with respect to the Securities that remains unclaimed for two years, subject to applicable unclaimed property laws. After return to the Company, Holders entitled to the money or securities must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person.

15. Amendment; Waiver.

Subject to certain exceptions set forth in the Indenture, (i) the Indenture or the Securities may be amended with the written consent of the Holders of at least a majority in aggregate Principal Amount at Maturity of the Securities at the time outstanding and (ii) certain Defaults may be waived with the written consent of the Holders of a majority in aggregate Principal Amount at Maturity of the Securities at the time outstanding. Subject to certain exceptions set forth in the Indenture, without the consent of any Securityholder, the Company and the Trustee may amend the Indenture or the Securities to cure any ambiguity, omission, defect or

A-2-14


inconsistency, or to comply with Article 5 or Section 10.14 of the Indenture, to secure the Company's obligations under this Security or to add to the Company's covenants for the benefit of the Securityholders or to surrender any right or power conferred, or to comply with any requirement of the SEC in connection with the qualification of the Indenture under the Trust Indenture Act of 1939 and any amendment thereof, or as necessary in connection with the registration of the Securities under the Securities Act or to make any change that does not adversely affect the rights of any Holders.

16. Defaults and Remedies.

Under the Indenture, Events of Default include (i) default in the payment of contingent interest when the same becomes due and payable, which default continues for 30 days; (ii) default in payment of the Principal Amount at Maturity, Issue Price plus accrued Original Issue Discount, Redemption Price, Purchase Price or Change in Control Purchase Price, as the case may be, in respect of the Securities when the same becomes due and payable; (iii) failure by the Company to comply with other agreements in the Indenture or the Securities, subject to notice and lapse of time; (iv) the acceleration of Debt in an amount in excess of $20,000,000 because of a default with respect to such Debt without such Debt having been discharged or such acceleration having been cured, waived, rescinded or annulled, subject to notice and lapse of time; provided, however, that if any such failure or acceleration referred to above shall cease or be cured, waived, rescinded or annulled, then the Event of Default by reason thereof shall be deemed not to have occurred; and (v) certain events of bankruptcy or insolvency. If an Event of Default occurs and is continuing, the Trustee, or the Holders of at least 25% in aggregate Principal Amount at Maturity of the Securities at the time outstanding, may declare the Issue Price plus the Original Issue Discount through the date of such declaration, and any accrued and unpaid interest (including contingent interest) if any, through the date of such declaration, on all the Securities to be due and payable immediately. Certain events of bankruptcy or insolvency are Events of Default which will result in the Issue Price plus the Original Issue Discount on the Securities, and any accrued and unpaid interest (including contingent interest) if any, through the occurrence of such event, becoming due and payable immediately upon the occurrence of such Events of Default.

Securityholders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Securities unless it receives indemnity or security reasonably satisfactory to it. Subject to certain limitations, Holders of a majority in aggregate Principal Amount at Maturity of the Securities at the time outstanding may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Securityholders notice of any continuing Default (except a Default in payment of amounts specified in clause (i) or (ii) above) if it determines that withholding notice is in their interests.

17. Trustee Dealings with the Company.

Subject to certain limitations imposed by the TIA, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.

A-2-15


18. No Recourse Against Others.

A director, officer, employee or stockholder, as such, of the Company shall not have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security, each Securityholder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities.

19. Authentication.

This Security shall not be valid until an authorized officer of the Trustee manually signs the Trustee's Certificate of Authentication on the other side of this Security.

20. Abbreviations.

Customary abbreviations may be used in the name of a Securityholder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with right of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act).

21. Original Issue Discount Information Reporting Requirements.

In accordance with the United States Treasury Regulation Section 1.1275-3, a Holder may obtain the projected payment schedule by submitting a written request for such information to the following representative of the Company: Corporate Secretary, 3M Office of General Counsel, 3M Center, St. Paul, MN 55133.

Ladies and Gentlemen:

We are delivering this letter in connection with the proposed transfer of beneficial interests in an amount equal to $__________ Principal Amount at Maturity of the Liquid Yield Option Notes due November 21, 2032 ("LYONs") of 3M Company (the "Company"), a Delaware corporation, which are convertible into shares of the Common Stock, $.01 par value per share (the "Common Stock"), of the Company.

We hereby confirm that:

(i) we are an "accredited investor" within the meaning of Rule
501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended (the "Securities Act") (an "Institutional Accredited Investor");

(ii) the purchase of beneficial interests in LYONs by us is for our own account or for the account of one or more other Institutional Accredited Investors or as fiduciary for the account of one or more trusts, each of which is an "accredited investor" within the meaning of Rule 501(a)(7) under the Securities Act and for each of which we exercise sole investment discretion, or (B) we are a "bank," within the meaning of Section 3(a)(2) of the Securities Act, or a "savings and loan association" or other institution described in
Section 3(a)(5)(A) of the Securities Act that is acquiring beneficial interests in LYONs as fiduciary for the account of one or more institutions for which we exercise sole investment discretion;

B-2-1


(iii) we will acquire beneficial interests in LYONs having a minimum principal amount at maturity of not less than $250,000 for our own account or for any separate account for which we are acting;

(iv) we have such knowledge and experience in financial and business matters that we are capable of evaluating the merits and risks of purchasing beneficial interests in LYONs;

(v) on each day from the date on which we acquire the beneficial interests in LYONs through and including the date on which we dispose of our beneficial interests in such LYONs or the LYONs are exchanged for the Common Stock, either: (i) we are not (A) an "employee benefit plan" subject to the fiduciary responsibility provisions of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), (B) a "plan" subject to Section 4975 of the Internal Revenue Code of 1986, as amended (the "Code"), (C) an entity whose underlying assets include the assets of any such employee benefit plan or plan by reason of Department of Labor Regulation Section 2510.3-101 or otherwise, or (D) a governmental plan that is subject to any federal, state or local law which is substantially similar to the provisions of Section 406 of ERISA or Section 4975 of the Code, or (ii) our acquisition, holding and subsequent disposition of LYONs or interest therein will not result in a prohibited transaction under Section 406 of ERISA or Section 4975 of the Code (or, in the case of a governmental plan, any substantially similar federal, state or local law) for which an exemption is not available, all the conditions of which are satisfied; and

(vi) we are not acquiring beneficial interests in LYONs with a view to distribution thereof or with any present intention of offering or selling beneficial interests in LYONs or the Common Stock deliverable upon exchange thereof, except as permitted below; provided that the disposition of our property and property of any accounts for which we are acting as fiduciary shall remain at all times within our control.

We understand that the LYONs were originally offered and sold in a transaction not involving any public offering within the United States within the meaning of the Securities Act and that the LYONs and the shares of Common Stock (the "Securities") deliverable upon exchange thereof have not been registered under the Securities Act, and we agree, on our own behalf and on behalf of each account for which we acquire any beneficial interests in LYONs, that if in the future we decide to resell or otherwise transfer such Securities prior to the Resale Restriction Termination Date (as defined below), such Securities may be resold or otherwise transferred only (i) to the Company or any Subsidiary thereof, (ii) for as long as the LYONs are eligible for resale pursuant to Rule 144A under the Securities Act ("Rule 144A"), to a person it reasonably believes is a "qualified institutional buyer" (as defined in Rule 144A) that purchases for its own account or for the account of a qualified institutional buyer to which notice is given that the transfer is being made in reliance on Rule 144A, (iii) to an Institutional Accredited Investor that is acquiring the Security for its own account, or for the account of such Institutional Accredited Investor for investment purposes and not with a view to, or for offer or sale in connection with, any distribution in violation of the Securities Act, (iv) pursuant to another available exemption from registration under the Securities Act (if applicable) or (v) pursuant to a registration statement which has been declared effective under the Securities Act and, in each

B-2-2


case, in accordance with any applicable securities laws of any State of the United States or any other applicable jurisdiction and in accordance with the legends set forth on the Securities. We further agree to provide any person purchasing any of the Securities other than pursuant to clause (v) above from us a notice advising such purchaser that resales of such securities are restricted as stated herein. We understand that the trustee or the transfer agent, as the case may be, for the Securities will not be required to accept for registration of transfer any Securities pursuant to (iii) or (iv) above except upon presentation of evidence satisfactory to the Company that the foregoing restrictions on transfer have been complied with. We further understand that the global security representing the Securities will bear a legend reflecting the substance of this paragraph until the Resale Restriction Termination Date other than certificates representing Securities transferred pursuant to clause (v) above. As used herein, "Resale Restriction Termination Date" means (a) with respect to any LYONs, the date that is two years after the later of the date of the original issuance of the LYONs and the last date on which the Company or any affiliate of the Company was the owner of such LYONs and (b) with respect to Common Stock delivered upon exchange of a LYON, the date that is two years after the later of the date on which such shares were so delivered upon exchange and the last date on which the Company or any affiliate of the Company was the owner of such shares of Common Stock. We understand that we may not, directly or indirectly, engage in any hedging transaction with regard to the LYONs except as permitted by the Securities Act.

We acknowledge that the Company, others and you will rely upon our confirmations, acknowledgments and agreements set forth herein, and we agree to notify you promptly in writing if any of our representations or warranties herein ceases to be accurate and complete.

THIS LETTER SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE

INTERNAL LAWS OF THE STATE OF NEW YORK.

* The comparable yield means the annual yield the Company would pay, as of the Issue Date, on a noncontingent, nonconvertible, fixed-rate debt security with terms and conditions otherwise comparable to those of the Securities. The schedule of projected payments has been determined on the basis of an assumption of linear growth of the stock price and a constant dividend yield and has not been determined for any purpose other than for the determination of interest accruals and adjustments thereof in respect of the Securities for United States federal income tax purposes. The comparable yield and the schedule of projected payments do not constitute a projection or representation regarding the amounts payable on the Securities.

REVERSE SIDE OF LYON
Liquid Yield Option(TM) Note due 2032
(Zero Coupon-Senior)

1. Interest.

This Security shall not bear interest, except as specified in this paragraph or in paragraph 5 hereof. If the Principal Amount at Maturity hereof or any portion of such Principal Amount at Maturity is not paid when due (whether upon acceleration pursuant to Section 6.02 of the Indenture, upon the date set for payment of the Redemption Price pursuant to paragraph 6 hereof, upon the date set for payment of the Purchase Price or Change in Control Purchase Price pursuant to paragraph 7 hereof or upon the Stated Maturity of this Security) or if any contingent interest due hereon is not paid when due in accordance with paragraph 5 hereof, then in each such case the overdue amount shall, to the extent permitted by law, bear interest at the rate of 0.5% per annum, compounded semiannually, which interest shall accrue from the date such overdue amount was originally due to the date payment of such amount, including interest thereon, has been made or duly provided for. All such interest shall be payable on demand. The accrual of such interest on overdue amounts shall be in lieu of, and not in addition to, the continued accrual of Original Issue Discount.

Original Issue Discount (the difference between the Issue Price and the Principal Amount at Maturity of the Security), in the period during which a Security remains outstanding, shall accrue at 0.5% per annum, on a semiannual bond equivalent basis using a 360-day year composed of twelve 30-day months, from the Issue Date of this Security.

2. Method of Payment.

Subject to the terms and conditions of the Indenture, the Company will make payments in respect of Redemption Prices, Purchase Prices, Change in Control Purchase Prices and Principal Amount at Maturity to Holders who surrender Securities to a Paying Agent to collect such payments in respect of the Securities. The Company will pay any cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. However, the Company may make such cash payments by check payable in such money.

3. Paying Agent, Conversion Agent, Registrar and Bid Solicitation Agent.

Initially, Citibank, N.A. (the "Trustee"), will act as Paying Agent, Conversion Agent, Registrar and Bid Solicitation Agent. The Company may appoint and change any Paying Agent, Conversion Agent, Registrar or co-registrar or Bid Solicitation Agent without notice, other than notice to the Trustee. The Company or any of its Subsidiaries or any of their Affiliates may act as Paying Agent, Conversion Agent, Registrar or co-registrar. None of the Company, any of its Subsidiaries or any of their Affiliates shall act as Bid Solicitation Agent.

4. Indenture.

The Company issued the Securities under an Indenture dated as of November 21, 2002 (the "Indenture"), between the Company and the Trustee. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust

4

Indenture Act of 1939, as in effect from time to time (the "TIA"). Capitalized terms used herein and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all such terms, and Securityholders are referred to the Indenture for a statement of those terms.

The Securities are general unsecured and unsubordinated obligations of the Company limited to $639,000,000 aggregate Principal Amount at Maturity (subject to Section 2.07 of the Indenture). The Indenture does not limit other indebtedness of the Company, secured or unsecured.

5. Contingent Interest.

Subject to the accrual and record date provisions specified in this Paragraph 5, the Company shall pay contingent cash interest to the Holders during any six-month period (a "Contingent Interest Period") from November 22 to May 21 and from May 22 to November 21, commencing on or after November 22, 2007, if the average LYON Market Price for the Applicable Five Trading Day Period with respect to such Contingent Interest Period equals 130% or more of the sum of the Issue Price of a Security and Original Issue Discount accrued thereon to the day immediately preceding the first day of the relevant Contingent Interest Period.

The amount of contingent interest payable per $1,000 Principal Amount at Maturity hereof in respect of any Quarterly Period within a Contingent Interest Period shall equal the greater of (x) Regular Cash Dividends paid by the Company per share of Common Stock during that Quarterly Period multiplied by the number of shares of Common Stock into which $1,000 Principal Amount at Maturity hereof is convertible pursuant to paragraph 9 hereof as of the accrual date for such contingent interest or (y) $0.62 multiplied by 4.7301, provided that if the Company does not pay cash dividends during a semiannual period, the Company will pay contingent interest semiannually at a rate of 0.5% of the average LYON Market Price for the Applicable Five Trading Day Period.

Contingent interest, if any, will accrue and be payable to Holders as of the record date for the related Regular Cash Dividend or, if no Regular Cash Dividend is paid by the Company during a Quarterly Period, to Holders as of the 15th day (whether or not a Business Day) preceding the last day of the relevant Contingent Interest Period. Such payments shall be paid on the payment date of the related Regular Cash Dividend or, if no Regular Cash Dividend is paid by the Company during any Quarterly Period, on the last day of the relevant Contingent Interest Period. Original Issue Discount will continue to accrue at 0.5% per annum whether or not contingent interest is paid.

"Applicable Five Trading Day Period" means, with respect to any Contingent Interest Period, the five Trading Days ending on the second Trading Day immediately preceding the first day of such Contingent Interest Period; provided, however, if the Company shall have declared a Regular Cash Dividend on its Common Stock that is payable during such Contingent Interest Period but for which the record date for determining stockholders entitled thereto precedes the first day of such Contingent Interest Period, then "Applicable Five Trading Day Period" shall mean, with respect to such Contingent Interest Period, the five Trading Days ending on the second Trading Day immediately preceding such record date.

5

"Regular Cash Dividends" means quarterly or other periodic cash dividends on the Company's Common Stock as declared by the Company's Board of Directors as part of its cash dividend payment practices and that are not designated by them as extraordinary or special or other nonrecurring dividends.

"LYON Market Price" means, as of any date of determination, the average of the secondary market bid quotations per $1,000 Principal Amount at Maturity obtained by the Bid Solicitation Agent for $10 million Principal Amount at Maturity of Securities at approximately 4:00 p.m., New York City time, on such determination date from three recognized securities dealers in The City of New York (none of which shall be an Affiliate of the Company) selected by the Company; provided, however, if (a) at least three such bids are not obtained by the Bid Solicitation Agent or (b) in the Company's reasonable judgment, the bid quotations are not indicative of the secondary market value of the Securities as of such determination date, then the LYON Market Price for such determination date shall equal (i) the Conversion Rate in effect as of such determination date multiplied by (ii) the average Sale Price of the Common Stock for the five Trading Days ending on such determination date, appropriately adjusted to take into account the occurrence, during the period commencing on the first of such Trading Days during such five Trading Day period and ending on such determination date, of any event described in Section 10.06, 10.07 or 10.08 (subject to the conditions set forth in Sections 10.09 and 10.10) of the Indenture.

The term "Quarterly Period" shall mean, with respect to any Contingent Interest Period, any quarterly period within such Contingent Interest Period extending from November 22 to February 21, from February 22 to May 21, from May 22 to August 21 or from August 22 to November 21.

Upon determination that Holders will be entitled to receive contingent interest which may become payable during a Contingent Interest Period, on or prior to the first day of such Contingent Interest Period, the Company shall promptly notify the Trustee of such determination and shall issue a press release and publish such information on its web site on the World Wide Web or through such other public medium as the Company may use at that time as soon as practicable. The Company shall also notify the Trustee of the declaration of any Regular Cash Dividends and the related record and payment dates.

The determination of the amount of contingent interest, if any, and the payment thereof is the sole responsibility of the Company.

6. Redemption at the Option of the Company.

No sinking fund is provided for the Securities. The Securities are redeemable for cash as a whole, at any time, or in part from time to time at the option of the Company in accordance with the Indenture at the Redemption Prices set forth below, provided that the Securities are not redeemable prior to November 21, 2007.

The table below shows Redemption Prices of a Security per $1,000 Principal Amount at Maturity on the dates shown below and at Stated Maturity, which prices reflect accrued Original Issue Discount calculated to each such date. The Redemption Price of a Security redeemed

between such dates shall include an additional amount reflecting the additional Original Issue Discount accrued since the preceding date in the table and until, but not including, the Redemption Date.

In addition to the Redemption Price payable with respect to all Securities or portions thereof to be redeemed as of a Redemption Date, the Holders of such Securities (or portions thereof) shall be entitled to receive accrued and unpaid contingent interest, if any, with respect thereto, which interest shall be paid in cash on the Redemption Date.

7

Maturity, upon delivery of a Purchase Notice containing the information set forth in the Indenture, at any time from the opening of business on the date that is 20 Business Days prior to such Purchase Date until the close of business on the Business Day immediately preceding such Purchase Date and upon delivery of the Securities to the Paying Agent by the Holder as set forth in the Indenture.

November 21, 2005                           $873.86
November 21, 2007                            882.64

November 21, 2027                            975.34

The Company may, from time to time, declare additional Purchase Dates and corresponding Purchase Prices.

The Purchase Price (equal to the Issue Price plus accrued Original Issue Discount to the Purchase Date) may be paid, at the option of the Company, in cash or by the issuance and delivery of shares of Common Stock of the Company, or in any combination thereof.

At the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase the Securities held by such Holder no later than 35 Business Days after the occurrence of a Change in Control of the Company, but in no event prior to the date on which such Change in Control occurs, on or prior to November 21, 2007 for a Change in Control Purchase Price equal to the Issue Price plus accrued Original Issue Discount to the Change in Control Purchase Date, which Change in Control Purchase Price shall be paid in cash.

A third party may make the offer and purchase of the Securities in lieu of the Company in accordance with the Indenture.

In addition to the Purchase Price or Change in Control Purchase Price, as the case may be, payable with respect to all Securities or portions thereof to be purchased as of the Purchase Date or the Change in Control Purchase Date, as the case may be, the Holders of such Securities (or portions thereof) shall be entitled to receive any accrued and unpaid contingent interest with respect thereto, which shall be paid in cash promptly following the later of the Purchase Date or the Change in Control Purchase Date, as the case may be and the time of delivery of such Securities to the Paying Agent pursuant to the Indenture.

Holders have the right to withdraw any Purchase Notice or Change in Control Purchase Notice, as the case may be, by delivering to the Paying Agent a written notice of withdrawal in accordance with the provisions of the Indenture.

8

If cash (and/or securities if permitted under the Indenture) sufficient to pay the Purchase Price or Change in Control Purchase Price, as the case may be, of, together with any accrued and unpaid contingent interest with respect to, all Securities or portions thereof to be purchased as of the Purchase Date or the Change in Control Purchase Date, as the case may be, is deposited with the Paying Agent on the Business Day following the Purchase Date or the Change in Control Purchase Date, as the case may be, Original Issue Discount and any contingent interest shall cease to accrue on such Securities (or portions thereof) immediately after such Purchase Date or Change in Control Purchase Date, as the case may be, and the Holder thereof shall have no other rights as such (other than the right to receive the Purchase Price or Change in Control Purchase Price, as the case may be, and any accrued and unpaid contingent interest upon surrender of such Security).

8. Notice of Redemption.

Notice of redemption will be mailed at least 30 days but not more than 60 days before the Redemption Date to each Holder of Securities to be redeemed at the Holder's registered address. If money sufficient to pay the Redemption Price of, and accrued and unpaid contingent interest, if any, with respect to, all Securities (or portions thereof) to be redeemed on the Redemption Date is deposited with the Paying Agent prior to or on the Redemption Date, on such Redemption Date, Original Issue Discount and contingent interest, if any, shall cease to accrue on such Securities or portions thereof. Securities in denominations larger than $1,000 of Principal Amount at Maturity may be redeemed in part but only in integral multiples of $1,000 of Principal Amount at Maturity.

9. Conversion.

Subject to the provisions of this Paragraph 9, a Holder of a Security may convert it into Common Stock of the Company at any time before the close of business on November 20, 2032. If the Security is called for redemption, the Holder may convert it only until the close of business on the second Business Day immediately preceding the Redemption Date. A Security in respect of which a Holder has delivered a Purchase Notice or Change in Control Purchase Notice exercising the option of such Holder to require the Company to purchase such Security may be converted only if such notice of exercise is withdrawn in accordance with the terms of the Indenture.

The initial Conversion Rate is 4.7301 shares of Common Stock per $1,000 Principal Amount at Maturity, subject to adjustment in certain events described in the Indenture. The Company will deliver cash or a check in lieu of any fractional share of Common Stock.

(a) CONVERSION BASED ON COMMON STOCK PRICE. Subject to the provisions of this Paragraph 9, Holders may convert the Securities into Common Stock in any calendar quarter commencing after March 31, 2003, if, as of the last day of the preceding calendar quarter, the Sale Price of the Common Stock for at least 20 Trading Days in a period of 30 consecutive Trading Days ending on the last Trading Day of such preceding calendar quarter is more than 130% of the accreted conversion price per share of Common Stock on the last day of such preceding calendar quarter.

9

The "accreted conversion price" per share of Common Stock as of any day equals the quotient of:

o the Issue Price of a Security and Accrued Original Issue Discount to that day, divided by

o the number of shares of Common Stock issuable upon conversion of $1,000 Principal Amount at Maturity of Securities on that day.

(b) CONVERSION BASED ON CREDIT RATING DOWNGRADE. Subject to the provisions of this Paragraph 9, Holders may convert the Securities into Common Stock on a Conversion Date during any period in which the credit rating assigned to the Securities by a Rating Agency is at or below the Applicable Rating. "Rating Agency" means Standard & Poor's Ratings Services, a division of The McGraw-Hill Companies Inc., and its successors ("Standard & Poor's"), or Moody's Investors Service ("Moody's"), or if neither Standard & Poor's nor Moody's are making ratings of the Securities publicly available, a nationally recognized U.S. rating agency or agencies, as the case may be, selected by the Company, which will be substituted for Standard & Poor's or Moody's, as the case may be. "Applicable Rating" means, in the case of Standard & Poor's, BBB+, or in the case of Moody's, Baa1 (or their respective equivalents under any successor ratings categories of Standard & Poor's or Moody's), or the equivalent in respect of ratings categories of any Rating Agencies substituted for Standard & Poor's or Moody's.

(c) CONVERSION BASED ON REDEMPTION. Subject to the provisions of this Paragraph 9, a Holder may convert into Common Stock a Security or portion of a Security which has been called for redemption pursuant to Paragraph 6 hereof, even if the Securities are not otherwise convertible at such time, but such Securities may be surrendered for conversion only until the close of business on the second Business Day immediately preceding the Redemption Date.

(d) CONVERSION UPON OCCURRENCE OF CERTAIN CORPORATE TRANSACTIONS. Subject to the provisions of this Paragraph 9, in the event the Company is a party to a consolidation, merger or binding share exchange or a transfer of all or substantially all assets of the Company pursuant to which the Common Stock would be converted into cash, securities or other property as set forth in
Section 10.14 of the Indenture, the Securities may be surrendered for conversion at any time from and after the date which is 15 days prior to the anticipated effective date until 15 days after the actual effective date of such transaction, and at the effective date of such transaction the right to convert a Security into Common Stock will be deemed to have changed into a right to convert it into the kind and amount of cash, securities or other assets of the Company or another person which the holder would have received if the holder had converted its Security immediately prior to the transaction.

A Holder's right to convert the Securities into Common Stock of the Company is also subject to the Company's right to elect to pay such Holder the amount of cash set forth in the next succeeding sentence (or an equivalent amount in a combination of cash and shares of Common Stock), in lieu of delivering all or part of such Common Stock; provided, however, that if such payment of cash is not permitted pursuant to the provisions of the Indenture, the

10

Company shall deliver Common Stock (and cash in lieu of fractional shares of Common Stock) in accordance with the Indenture, whether or not the Company has delivered a notice pursuant to the Indenture to the effect that the Securities will be paid in cash. The amount of cash to be paid for each $1,000 Principal Amount at Maturity of Securities shall be equal to the average Sale Price of a share of Common Stock of the Company for the five consecutive Trading Days immediately following (i) the date of the Company's notice of its election to deliver cash upon conversion, if the Company has not given a notice of redemption pursuant to the Indenture, or (ii) the Conversion Date, in the case of a conversion following such a notice of redemption specifying an intent to deliver cash or a combination of cash and Common Stock upon conversion, in either case multiplied by the Conversion Rate in effect on such Conversion Date. If the Company shall elect to make such payment wholly in shares of Common Stock, then such shares shall be delivered through the Conversion Agent to Holders surrendering Securities as promptly as practicable but in any event no later than the fifth Business Day following the Conversion Date. If, however, the Company elects to make any portion of such payment in cash, then the payment, including any delivery of shares of Common Stock, shall be made to Holders surrendering Securities no later than the tenth Business Day following the Conversion Date.

The Company may not pay cash in lieu of delivering all or part of such share of Common Stock upon the conversion of any Securities pursuant to the terms of the Indenture (other than cash in lieu of fractional shares) if there has occurred (prior to, on or after, as the case may be, the Conversion Date or the date on which the Company delivers its notice specifying whether each Conversion shall be converted into shares of Common Stock or cash) and is continuing an Event of Default (other than a default in such payment on such Securities).

Accrued and unpaid contingent interest will not be paid in cash on Securities that are converted but will be paid in the manner provided in the following paragraph; provided, however that Securities surrendered for conversion during the period from the close of business on any date on which contingent interest accrues to the opening of business on the date on which such contingent interest is payable, shall be entitled to receive such contingent interest payable on such Securities on the corresponding Interest Payment Date or the date on which such contingent interest is payable and (except Securities with respect to which the Company has mailed a notice of redemption) Securities surrendered for conversion during such periods must be accompanied by payment of an amount equal to the contingent interest with respect thereto that the registered Holder is to receive.

A Holder may convert a portion of a Security if the Principal Amount at Maturity of such portion is $1,000 or an integral multiple of $1,000. No payment or adjustment will be made for dividends on the Common Stock except as provided in the Indenture. On conversion of a Security, accrued Original Issue Discount attributable to the period from the Issue Date through the Conversion Date, accrued Tax OID and (except as provided above) accrued contingent interest with respect to the converted Security shall not be cancelled, extinguished or forfeited, but rather shall be deemed to be paid in full to the Holder thereof through the delivery of the Common Stock (together with the cash payment, if any, in lieu of fractional shares), or cash or a combination of cash and Common Stock in lieu thereof, in exchange for the Security being converted pursuant to the terms hereof; and the fair market value of such shares of Common Stock (together with any such cash payment in lieu of fractional shares), or cash or a combination of cash and Common Stock in lieu thereof, shall be treated as delivered, to the

11

extent thereof, first in exchange for Original Issue Discount and Tax OID accrued through the Conversion Date and accrued contingent interest, if any, and the balance, if any, of such cash and/or the fair market value of such Common Stock (and any such cash payment in lieu of fractional shares), or cash in lieu thereof, shall be treated as delivered in exchange for the Issue Price of the Security being converted pursuant to the provisions hereof.

The Company agrees, and each Holder and any beneficial owner of a Security by its purchase thereof shall be deemed to agree, to treat, for United States federal income tax purposes, the fair market value of the Common Stock received upon the conversion of a Security (together with any cash payment in lieu of fractional shares) or cash, or a combination of cash and Common Stock as a contingent payment on the Security for purposes of Treasury Regulation Section 1.1275-4(b).

To convert a Security, a Holder must (1) complete and manually sign the conversion notice below (or complete and manually sign a facsimile of such notice) and deliver such notice to the Conversion Agent, (2) surrender the Security to the Conversion Agent, (3) furnish appropriate endorsements and transfer documents if required by the Conversion Agent, the Company or the Trustee and (4) pay any transfer or similar tax, if required.

The Conversion Rate will be adjusted for dividends or distributions on Common Stock payable in Common Stock or other Capital Stock; subdivisions, combinations or certain reclassifications of Common Stock; distributions to all holders of Common Stock of certain rights to purchase Common Stock for a period expiring within 60 days of the record date for such distribution at less than the Sale Price of the Common Stock at the Time of Determination; and distributions to such holders of assets (including shares of Capital Stock of a Subsidiary) or debt securities of the Company or certain rights to purchase securities of the Company (excluding certain cash dividends or distributions). However, no adjustment need be made if Securityholders may participate in the transaction or in certain other cases. The Company from time to time may voluntarily increase the Conversion Rate.

If the Company is a party to a consolidation, merger or binding share exchange or a transfer of all or substantially all of its assets, or upon certain distributions described in the Indenture, the right to convert a Security into Common Stock may be changed into a right to convert it into the kind and amount of securities, cash or other assets of the Company or another person which the Holder would have received if the Holder had converted its Securities immediately prior to the transaction.

10. Conversion Arrangement on Call for Redemption.

Any Securities called for redemption, unless surrendered for conversion before the close of business on the Redemption Date, may be deemed to be purchased from the Holders of such Securities at an amount not less than the Redemption Price, by one or more investment bankers or other purchasers who may agree with the Company to purchase such Securities from the Holders, to convert them into Common Stock of the Company and to make payment for such Securities to the Trustee in trust for such Holders.

12

11. Defaulted Interest.

Except as otherwise specified with respect to the Securities, any Defaulted Interest on any Security shall forthwith cease to be payable to the registered Holder thereof on the relevant accrual date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company as provided for in Section 11.02 of the Indenture.

12. Denominations; Transfer; Exchange.

The Securities are in fully registered form, without coupons, in denominations of $1,000 of Principal Amount at Maturity and integral multiples of $1,000. A Holder may transfer or exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not register the transfer or exchange of any Securities selected for redemption (except, in the case of a Security to be redeemed in part, the portion of the Security not to be redeemed) or any Securities in respect of which a Purchase Notice or Change in Control Purchase Notice has been given and not withdrawn (except, in the case of a Security to be purchased in part, the portion of the Security not to be purchased) or any Securities for a period of 15 days before the mailing of a notice of redemption of Securities to be redeemed.

13. Persons Deemed Owners.

The registered Holder of this Security may be treated as the owner of this Security for all purposes.

14. Unclaimed Money or Securities.

The Trustee and the Paying Agent shall return to the Company upon written request any money or securities held by them for the payment of any amount with respect to the Securities that remains unclaimed for two years, subject to applicable unclaimed property laws. After return to the Company, Holders entitled to the money or securities must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person.

15. Amendment; Waiver.

Subject to certain exceptions set forth in the Indenture, (i) the Indenture or the Securities may be amended with the written consent of the Holders of at least a majority in aggregate Principal Amount at Maturity of the Securities at the time outstanding and (ii) certain Defaults may be waived with the written consent of the Holders of a majority in aggregate Principal Amount at Maturity of the Securities at the time outstanding. Subject to certain exceptions set forth in the Indenture, without the consent of any Securityholder, the Company and the Trustee may amend the Indenture or the Securities to cure any ambiguity, omission, defect or inconsistency, or to comply with Article 5 or Section 10.14 of the Indenture, to secure the Company's obligations under this Security or to add to the Company's covenants for the benefit of the Securityholders or to surrender any right or power conferred, or to comply with any requirement of the SEC in connection with the qualification of the Indenture under the Trust

13

Indenture Act of 1939 and any amendment thereof, or as necessary in connection with the registration of the Securities under the Securities Act or to make any change that does not adversely affect the rights of any Holders.

16. Defaults and Remedies.

Under the Indenture, Events of Default include (i) default in the payment of contingent interest when the same becomes due and payable, which default continues for 30 days; (ii) default in payment of the Principal Amount at Maturity, Issue Price plus accrued Original Issue Discount, Redemption Price, Purchase Price or Change in Control Purchase Price, as the case may be, in respect of the Securities when the same becomes due and payable; (iii) failure by the Company to comply with other agreements in the Indenture or the Securities, subject to notice and lapse of time; (iv) the acceleration of Debt in an amount in excess of $20,000,000 because of a default with respect to such Debt without such Debt having been discharged or such acceleration having been cured, waived, rescinded or annulled, subject to notice and lapse of time; provided, however, that if any such failure or acceleration referred to above shall cease or be cured, waived, rescinded or annulled, then the Event of Default by reason thereof shall be deemed not to have occurred; and (v) certain events of bankruptcy or insolvency. If an Event of Default occurs and is continuing, the Trustee, or the Holders of at least 25% in aggregate Principal Amount at Maturity of the Securities at the time outstanding, may declare the Issue Price plus the Original Issue Discount through the date of such declaration, and any accrued and unpaid interest (including contingent interest) if any, through the date of such declaration, on all the Securities to be due and payable immediately. Certain events of bankruptcy or insolvency are Events of Default which will result in the Issue Price plus the Original Issue Discount on the Securities, and any accrued and unpaid interest (including contingent interest) if any, through the occurrence of such event, becoming due and payable immediately upon the occurrence of such Events of Default.

Securityholders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Securities unless it receives indemnity or security reasonably satisfactory to it. Subject to certain limitations, Holders of a majority in aggregate Principal Amount at Maturity of the Securities at the time outstanding may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Securityholders notice of any continuing Default (except a Default in payment of amounts specified in clause (i) or (ii) above) if it determines that withholding notice is in their interests.

17. Trustee Dealings with the Company.

Subject to certain limitations imposed by the TIA, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.

14

18. No Recourse Against Others.

A director, officer, employee or stockholder, as such, of the Company shall not have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security, each Securityholder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities.

19. Authentication.

This Security shall not be valid until an authorized officer of the Trustee manually signs the Trustee's Certificate of Authentication on the other side of this Security.

20. Abbreviations.

Customary abbreviations may be used in the name of a Securityholder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with right of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act).

SECTION 2. Shelf Registration.

(a) The Company shall prepare and file or cause to be prepared and filed with the SEC no later than a date which is ninety (90) days after the Issue Date (the "Filing Deadline Date") a Registration Statement for an offering to be made on a delayed or continuous basis pursuant to Rule 415 of the Securities Act (a "Shelf Registration Statement") registering the resale from time to time by Holders thereof of all of the Registrable Securities (the "Initial Shelf Registration Statement"). The Initial Shelf Registration Statement shall be on Form S-3 or another appropriate form permitting registration of such Registrable Securities for resale by such Holders in accordance with the methods of distribution reasonably elected by the Holders and set forth in the Initial Shelf Registration Statement; provided, that in no event will such method(s) of distribution take the form of an underwritten offering of the Registrable Securities without the prior agreement of the Company. The Company shall use reasonable efforts to cause the Initial Shelf Registration Statement to be declared effective under the Securities Act by the date (the "Effectiveness Deadline Date") that is one hundred and eighty (180) days after the Issue Date, and to keep the Initial Shelf Registration Statement (or any Subsequent Shelf Registration Statement) continuously effective under the Securities Act until the expiration of the Effectiveness Period subject to the rights of the Company under Section 3(i) to create a Deferral Period. At the time the Initial Shelf Registration Statement is declared effective, each Holder that became a Notice Holder on or prior to the date 10 Business Days prior to such time of effectiveness shall be named as a selling securityholder in the Initial Shelf Registration Statement and the related Prospectus in such a manner as to permit such Holder to deliver such Prospectus to purchasers of Registrable Securities in accordance with applicable law under ordinary circumstances, subject to compliance with blue sky laws. None of the Company's securityholders (other than the Holders of Registrable Securities) shall have the right to include any of the Company's securities in the Shelf Registration Statement.

(b) If the Initial Shelf Registration Statement or any Subsequent Shelf Registration Statement ceases to be effective other than during a Deferral Period for any reason at any time during the Effectiveness Period, the Company shall use reasonable efforts to obtain the prompt withdrawal of any order suspending the effectiveness thereof, and in any event shall within thirty (30) days of such cessation of effectiveness amend the Shelf Registration Statement

4

in a manner reasonably expected by the Company to obtain the withdrawal of the order suspending the effectiveness thereof, or file an additional Shelf Registration Statement covering all of the Securities that as of the date of such filing are Registrable Securities (a "Subsequent Shelf Registration Statement"). If a Subsequent Shelf Registration Statement is filed, the Company shall use reasonable efforts to cause the Subsequent Shelf Registration Statement to become effective as promptly as reasonably practicable after such filing, unless during a Deferral Period, or, if filed during a Deferral Period, after the expiration of a Deferral Period, and to keep such Registration Statement (or subsequent Shelf Registration Statement) continuously effective until the end of the Effectiveness Period.

(c) The Company shall supplement and amend the Shelf Registration Statement if required by the rules, regulations or instructions applicable to the registration form used by the Company for such Shelf Registration Statement, if required by the Securities Act or, to the extent to which the Company does not reasonably object, as reasonably requested by the Initial Purchaser or by the Trustee on behalf of the registered Holders.

(d) Each Holder of Registrable Securities agrees that if such Holder wishes to sell Registrable Securities pursuant to a Shelf Registration Statement and related Prospectus, it will do so only in accordance with this
Section 2(d) and Section 3(i). Each Holder of Registrable Securities wishing to sell Registrable Securities pursuant to a Shelf Registration Statement and related Prospectus agrees to deliver a Notice and Questionnaire to the Company at least ten (10) Business Days prior to any intended distribution of Registrable Securities under the Shelf Registration Statement. From and after the date the Initial Shelf Registration Statement is declared effective, the Company shall, as promptly as reasonably practicable after the date a Notice and Questionnaire is delivered, (i) if required by applicable law, file with the SEC a post-effective amendment to the Shelf Registration Statement or prepare and, if required by applicable law, file a supplement to the related Prospectus or a supplement or amendment to any document incorporated therein by reference or file any other document required by the SEC so that the Holder delivering such Notice and Questionnaire is named as a selling securityholder in the Shelf Registration Statement and the related Prospectus in such a manner as to permit such Holder to deliver such Prospectus to purchasers of the Registrable Securities in accordance with applicable law and, if the Company shall file a post-effective amendment to the Shelf Registration Statement, use reasonable efforts to cause such post-effective amendment to be declared effective under the Securities Act as promptly as reasonably practicable; (ii) provide such Holder copies of any documents filed pursuant to Section 2(d)(i); and (iii) notify such Holder as promptly as reasonably practicable after the effectiveness under the Securities Act of any post-effective amendment filed pursuant to
Section 2(d)(i); provided, that if such Notice and Questionnaire is delivered during a Deferral Period, the Company shall so inform the Holder delivering such Notice and Questionnaire and shall take the actions set forth in clauses (i),
(ii) and (iii) above upon expiration of the Deferral Period in accordance with
Section 3(i), provided, further, that if under applicable law the Company has more than one option as to the type or manner of making any such filing, as set forth in an opinion of nationally-recognized counsel experienced in such matters delivered by the Holder to the Company, it will make the required filing or filings in the manner or of a type that is reasonably expected to result in the earliest availability of the Prospectus for effecting resales of Registrable Securities unless such option would be adverse to the Company or result in increased costs. Notwithstanding anything contained herein to the contrary, the Company shall be under no obligation to name any Holder

5

that is not a Notice Holder as a selling securityholder in any Registration Statement or related Prospectus; provided, however, that any Holder that becomes a Notice Holder pursuant to the provisions of Section 2(d) of this Agreement (whether or not such Holder was a Notice Holder at the time the Registration Statement was initially declared effective) shall be named as a selling securityholder in the Registration Statement or related Prospectus subject to and in accordance with the requirements of this Section 2(d).

(e) The parties hereto agree that the Holders of Registrable Securities will suffer damages, and that it would not be feasible to ascertain the extent of such damages with precision, if (i) the Initial Shelf Registration Statement has not been filed on or prior to the Filing Deadline Date, (ii) the Initial Shelf Registration Statement has not been declared effective under the Securities Act on or prior to the Effectiveness Deadline Date, or (iii) the aggregate duration of Deferral Periods in any period exceeds the number of days permitted in respect of such period pursuant to Section 3(i) hereof (each of the events of a type described in any of the foregoing clauses (i) through (iii) are individually referred to herein as an "Event," and the Filing Deadline Date in the case of clause (i), the Effectiveness Deadline Date in the case of clause
(ii), and the date on which the aggregate duration of Deferral Periods in any period exceeds the number of days permitted by Section 3(i) hereof in the case of clause (iii), being referred to herein as an "Event Date"). Events shall be deemed to continue until the "Event Termination Date," which shall be the following dates with respect to the respective types of Events: the date the Initial Shelf Registration Statement is filed in the case of an Event of the type described in clause (i), the date the Initial Shelf Registration Statement is declared effective under the Securities Act in the case of an Event of the type described in clause (ii), termination of the Deferral Period that caused the limit on the aggregate duration of Deferral Periods in a period set forth in
Section 3(i) to be exceeded in the case of the commencement of an Event of the type described in clause (iii).

Accordingly, commencing on (and including) any Event Date and ending on (but excluding) the next date on which there are no Events that have occurred and are continuing (a "Damages Accrual Period"), the Company agrees to pay, as liquidated damages and not as a penalty, an amount (the "Liquidated Damages Amount"), payable on the Damages Payment Dates to Record Holders of then outstanding LYONs that are Registrable Securities or of then outstanding shares of Underlying Common Stock issued upon conversion of LYONs that are Registrable Securities, if any, as the case may be, accruing, for each portion of such Damages Accrual Period beginning on and including a Damages Payment Date (or, in respect of the first time that the Liquidation Damages Amount is to be paid to Holders on a Damages Payment Date as a result of the occurrence of any particular Event occurring since the most recent Damages Payment Event, from the Event Date) and ending on but excluding the first to occur of (A) the date of the end of the Damages Accrual Period or (B) the next Damages Payment Date, at a rate per annum equal to one-quarter of one percent (0.25%) for the first 90-day period from the Event Date, and thereafter at a rate per annum equal to one-half of one percent (0.5%) of the aggregate Applicable Principal Amount of such LYONs to the Record Holder of the then outstanding LYONs that are Registrable Securities or the aggregate Applicable Conversion Price of the shares of Underlying Common Stock to the Record Holder of the then outstanding shares of Underlying Common Stock that are Registrable Securities, as the case may be, in each case determined as of the Business Day immediately preceding the next Damages Payment Date; provided, that any Liquidated Damages Amount accrued with respect to any LYON or portion thereof called for redemption on a redemption date or converted into Underlying Common Stock

6

on a conversion date prior to the Damages Payment Date, shall, in any such event, be paid instead to the Holder who submitted such LYON or portion thereof for redemption or conversion on the applicable redemption date or conversion date, as the case may be, on such date (or promptly following the conversion date, in the case of conversion). Notwithstanding the foregoing, no Liquidated Damages Amounts shall accrue as to any Registrable Security from and after the earlier of (x) the date such security is no longer a Registrable Security and
(y) expiration of the Effectiveness Period. The rate of accrual of the Liquidated Damages Amount with respect to any period shall not exceed the rate provided for in this paragraph notwithstanding the occurrence of multiple concurrent Events. Following the cure of all Events requiring the payment by the Company of Liquidated Damages Amounts to the Holders of Registrable Securities pursuant to this Section, the accrual of Liquidated Damages Amounts will cease (without in any way limiting the effect of any subsequent Event requiring the payment of the Liquidated Damages Amount by the Company ) and accrued and unpaid Liquidated Damages will be paid in cash to the date of such cure to the Holder of record as of the date of such cure on the immediately succeeding Damages Payment Date.

The Trustee shall be entitled, on behalf of Holders of LYONs or Underlying Common Stock, to seek any available remedy for the enforcement of this Agreement, including for the payment of any Liquidated Damages Amount. Notwithstanding the foregoing, the parties agree that the sole remedy for a violation of the terms of this Agreement with respect to which liquidated damages are expressly provided shall be such liquidated damages.

All of the Company's obligations set forth in this Section 2(e) that are outstanding with respect to any Registrable Security at the time such Security ceases to be a Registrable Security shall survive until such time as all such obligations with respect to such security have been satisfied in full (notwithstanding termination of this Agreement pursuant to Section 8(j)).

The parties hereto agree that the liquidated damages provided for in this Section 2(e) constitute a reasonable estimate of the damages that may be incurred by Holders of Registrable Securities by reason of the failure of the Shelf Registration Statement to be filed or declared effective or available for effecting resales of Registrable Securities in accordance with the provisions hereof.

SECTION 3. Registration Procedures. In connection with the registration obligations of the Company under Section 2 hereof, the Company shall:

(a) Before filing any Registration Statement or Prospectus or any amendments or supplements thereto with the SEC, furnish to the Initial Purchaser copies of all such documents proposed to be filed and use reasonable efforts to reflect in each such document when so filed with the SEC such comments as the Initial Purchaser reasonably shall propose.

(b) Prepare and file with the SEC such amendments and post-effective amendments to each Registration Statement as may be necessary to keep such Registration Statement continuously effective for the applicable period specified in Section 2(a); cause the related Prospectus to be supplemented by any required Prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 (or any similar provisions then in force) under the Securities Act; and use reasonable efforts to comply with the provisions of the Securities Act

7

applicable to it with respect to the disposition of all securities covered by such Registration Statement during the Effectiveness Period in accordance with the intended methods of disposition by the sellers thereof set forth in such Registration Statement as so amended or such Prospectus as so supplemented.

(c) As promptly as reasonably practicable give notice to the Notice Holders and the Initial Purchaser (i) when any Prospectus, Prospectus supplement (except a Prospectus Supplement filed with the SEC solely to amend the selling security holder table), Registration Statement or post-effective amendment to a Registration Statement has been filed with the SEC and, with respect to a Registration Statement or any post-effective amendment, when the same has been declared effective, by release made to Reuters Economic Services and Bloomberg Business News or other reasonable means of distribution, including by notice posted on the Company's website on the worldwide web, (ii) of any request, following the effectiveness of the Initial Shelf Registration Statement under the Securities Act, by the SEC or any other federal or state governmental authority for amendments or supplements to any Registration Statement or related Prospectus or for additional information, (iii) of the issuance by the SEC or any other federal or state governmental authority of any stop order suspending the effectiveness of any Registration Statement or the initiation or threatening of any proceedings for that purpose, (iv) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose, (v) of the occurrence of (but not the nature of or details concerning) a Material Event (provided, however, that no notice by the Company shall be required pursuant to this clause (v) in the event that the Company either promptly files a Prospectus supplement to update the Prospectus or a Form 8-K or other appropriate Exchange Act report that is incorporated by reference into the Registration Statement, which, in either case, contains the requisite information with respect to such Material Event that results in such Registration Statement no longer containing any untrue statement of material fact or omitting to state a material fact necessary to make the statements contained therein not misleading) and (vi) of the determination by the Company that a post-effective amendment to a Registration Statement will be filed with the SEC, which notice may, at the discretion of the Company (or as required pursuant to Section 3(i)), state that it constitutes a Deferral Notice, in which event the provisions of Section 3(i) shall apply.

(d) Use reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of a Registration Statement or the lifting of any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction in which they have been qualified for sale, in either case at the earliest possible moment or, if a Deferral Period is in effect, at the earliest possible moment after the Deferral Period.

(e) If reasonably requested by the Initial Purchaser or any Notice Holder, as promptly as reasonably practicable incorporate in a Prospectus supplement or post-effective amendment to a Registration Statement such information as the Initial Purchaser or such Notice Holder shall, on the basis of an opinion of nationally-recognized counsel experienced in such matters, determine to be required to be included therein by applicable law and make any required filings of such Prospectus supplement or such post-effective amendment; provided, that the Company shall not be required to take any actions under this
Section 3(e) that are not, in the reasonable opinion of counsel for the Company, in compliance with applicable law.

8

(f) As promptly as reasonably practicable furnish to each Notice Holder and the Initial Purchaser, upon their request and without charge, at least one (1) conformed copy of the Registration Statement and any amendment thereto, including financial statements, but excluding schedules, all documents incorporated or deemed to be incorporated therein by reference and all exhibits (unless requested in writing to the Company by such Notice Holder or the Initial Purchaser, as the case may be).

(g) During the Effectiveness Period, deliver to each Notice Holder in connection with any sale of Registrable Securities pursuant to a Registration Statement, without charge, as many copies of the Prospectus or Prospectuses relating to such Registrable Securities (including each preliminary prospectus) and any amendment or supplement thereto as such Notice Holder may reasonably request; and the Company hereby consents (except during such periods that a Deferral Notice is outstanding and has not been revoked) to the use of such Prospectus or each amendment or supplement thereto by each Notice Holder in connection with any offering and sale of the Registrable Securities covered by such Prospectus or any amendment or supplement thereto in the manner set forth therein.

(h) Subject to Section 3(i), prior to any public offering of the Registrable Securities pursuant to the Shelf Registration Statement, use reasonable efforts to register or qualify or cooperate with the Notice Holders in connection with the registration or qualification (or exemption from such registration or qualification) of such Registrable Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions within the United States as any Notice Holder reasonably requests in writing (which request may be included in the Notice and Questionnaire) it being agreed that no such registration or qualification will be made unless so requested; prior to any public offering of the Registrable Securities pursuant to the Shelf Registration Statement, use reasonable efforts to keep each such registration or qualification (or exemption therefrom) effective during the Effectiveness Period in connection with such Notice Holder's offer and sale of Registrable Securities pursuant to such registration or qualification (or exemption therefrom) and do any and all other acts or things necessary to enable the disposition in such jurisdictions of such Registrable Securities in the manner set forth in the relevant Registration Statement and the related Prospectus; provided, that the Company will not be required to (i) qualify as a foreign corporation or as a dealer in securities in any jurisdiction where it is not otherwise qualified but for this Agreement or (ii) take any action that would subject it to general service of process in suits or to taxation in any such jurisdiction where it is not then so subject.

(i) Upon (A) the issuance by the SEC of a stop order suspending the effectiveness of the Shelf Registration Statement or the initiation of proceedings with respect to the Shelf Registration Statement under Section 8(d) or 8(e) of the Securities Act, (B) the occurrence of any event or the existence of any fact (a "Material Event") as a result of which any Registration Statement shall contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, or any Prospectus shall contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or (C) the occurrence or existence of any corporate development that, in the discretion of the Company, makes it appropriate to suspend the availability of the Shelf Registration Statement and the

9

related Prospectus, (i) in the case of clause (B) above, subject to the next sentence, as promptly as reasonably practicable prepare and file a post-effective amendment to such Registration Statement or a supplement to the related Prospectus or any document incorporated therein by reference or file any other required document that would be incorporated by reference into such Registration Statement and Prospectus so that such Registration Statement does not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and such Prospectus does not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, as thereafter delivered to the purchasers of the Registrable Securities being sold thereunder, and, in the case of a post-effective amendment to a Registration Statement, subject to the next sentence, use reasonable efforts to cause it to be declared effective as promptly as is reasonably practicable, and (ii) give notice to the Notice Holders that the availability of the Shelf Registration Statement is suspended (a "Deferral Notice") and, upon receipt of any Deferral Notice, each Notice Holder agrees not to sell any Registrable Securities pursuant to the Registration Statement until such Notice Holder's receipt of copies of the supplemented or amended Prospectus provided for in clause (i) above, or until it is advised in writing by the Company that the Prospectus may be used, and has received copies of any additional or supplemental filings that are incorporated or deemed incorporated by reference in such Prospectus. The Company will use all reasonable efforts to ensure that the use of the Prospectus may be resumed (x) in the case of clause (A) above, as promptly as reasonably practicable, (y) in the case of clause (B) above, as soon as, in the sole judgment of the Company, public disclosure of such Material Event would not be prejudicial to or contrary to the interests of the Company or, if necessary to avoid unreasonable burden or expense, as soon as reasonably practicable thereafter and (z) in the case of clause (C) above, as soon as, in the discretion of the Company, such suspension is no longer appropriate. The period during which the availability of the Registration Statement and any Prospectus is suspended (the "Deferral Period") shall, without the Company incurring any obligation to pay liquidated damages pursuant to Section 2(e), not exceed forty-five (45) days in any three (3) month period or ninety (90) days in any twelve (12) month period.

(j) If reasonably requested in writing in connection with a disposition of Registrable Securities in an underwritten offering pursuant to a Registration Statement, make reasonably available for inspection during normal business hours by a representative for the Notice Holders of such Registrable Securities and any broker-dealers, attorneys and accountants retained by such Notice Holders, all relevant financial and other records, pertinent corporate documents and properties of the Company and its subsidiaries, and cause the appropriate executive officers, directors and designated employees of the Company and its subsidiaries to make reasonably available for inspection during normal business hours all relevant information reasonably requested by such representative for the Notice Holders or any such broker-dealers, attorneys or accountants in connection with such disposition, in each case as is customary for similar "due diligence" examinations; provided, however, that such persons shall first agree in writing with the Company that any information that is reasonably designated by the Company in writing as confidential at the time of delivery of such information shall be kept confidential by such persons and shall be used solely for the purposes of exercising rights under this Agreement and such person shall comply with applicable securities laws, unless (i) disclosure of such information is required by court or administrative order or is necessary to respond to inquiries of

10

regulatory authorities, (ii) disclosure of such information is required by law (including any disclosure requirements pursuant to federal securities laws in connection with the filing of any Registration Statement or the use of any Prospectus referred to in this Agreement), (iii) such information becomes generally available to the public other than as a result of a disclosure or failure to safeguard by any such person or (iv) such information becomes available to any such person from a source other than the Company and such source is not bound by a confidentiality agreement; and provided further, that the foregoing inspection and information gathering shall, to the greatest extent possible, be coordinated on behalf of all the Notice Holders and the other parties entitled thereto by the counsel referred to in Section 5.

(k) Comply with all applicable rules and regulations of the SEC and make generally available to its securityholders earning statements (which need not be audited) satisfying the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any similar rule promulgated under the Securities Act) no later than 90 days after the end of the first 12-month period constituting a fiscal year commencing on the first day of the first fiscal quarter of the first fiscal year of the Company commencing after the effective date of a Registration Statement, which statements shall cover said 12-month periods.

(l) Cooperate with each Notice Holder to facilitate the timely preparation and delivery of certificates representing Registrable Securities sold pursuant to a Registration Statement, and cause such Registrable Securities to be in such denominations as are permitted by the Indenture and registered in such names as such Notice Holder may request in writing at least two Business Days prior to any sale of such Registrable Securities.

(m) Provide a CUSIP number for all Registrable Securities covered by each Registration Statement not later than the effective date of such Registration Statement and provide the Trustee for the LYONs and the transfer agent for the Common Stock with certificates for the Registrable Securities that are in a form eligible for deposit with The Depository Trust Company.

(n) Make reasonable effort to provide such information as is required for any filings required to be made with the National Association of Securities Dealers, Inc.

(o) Upon (i) the filing of the Initial Shelf Registration Statement and (ii) the effectiveness of the Initial Shelf Registration Statement, announce the same, in each case by release to Reuters Economic Services and Bloomberg Business News or other reasonable means of distribution.

(p) Enter into such customary agreements and take all such other reasonable necessary actions in connection therewith (including those reasonably requested by the holders of a majority of the Registrable Securities being sold) in order to expedite or facilitate disposition of such Registrable Securities; provided that the Company shall not be required to take any action in connection with an underwritten offering without its consent; and

(q) Cause the Indenture to be qualified under the TIA not later than the effective date of any Registration Statement; and in connection therewith, cooperate with the Trustee to effect such changes to the Indenture as may be required for the Indenture to be so

11

qualified in accordance with the terms of the TIA and execute, and use reasonable efforts to cause the Trustee to execute, all documents as may be required to effect such changes, and all other forms and documents required to be filed with the SEC to enable the Indenture to be so qualified in a timely manner.

SECTION 4. Holder's Obligations. Each Holder agrees, by acquisition of the Registrable Securities, that no Holder of Registrable Securities shall be entitled to sell any of such Registrable Securities pursuant to a Registration Statement or to receive a Prospectus relating thereto, unless such Holder has furnished the Company with a Notice and Questionnaire as required pursuant to
Section 2(d) hereof (including the information required to be included in such Notice and Questionnaire) and the information set forth in the next sentence. Each Notice Holder agrees promptly to furnish to the Company all information required to be disclosed in order to make the information previously furnished to the Company by such Notice Holder not misleading and any other information regarding such Notice Holder and the distribution of such Registrable Securities as may be required to be disclosed in the Registration Statement under applicable law or pursuant to SEC comments. Each Holder further agrees, following termination of the Effectiveness Period, to notify the Company within 10 business days of request, of the amount of Registrable Securities sold pursuant to the Registration Statement and, in the absence of a response, the Company may assume that all of the Holder's Registrable Securities were so sold.

SECTION 5. Registration Expenses. The Company shall bear all fees and expenses incurred in connection with the performance by the Company of its obligations under Sections 2 and 3 of this Agreement whether or not any of the Registration Statements are declared effective.

(v) reasonable fees and disbursements of the Trustee and its counsel and of the registrar and transfer agent for the Common Stock. In addition, the Company shall bear or reimburse the Notice Holders for the fees and disbursements of one firm of legal counsel for the Holders, which shall be Sidley Austin Brown & Wood LLP or another nationally recognized law firm experienced in securities law matters designated by the Company and consented to by the Initial Purchaser (which consent shall not be unreasonably withheld). In addition, the Company shall pay the internal expenses of the Company (including, without limitation, all salaries and expenses of officers and employees performing legal or accounting duties), the expense of any annual audit, the fees and expenses incurred in connection with the listing of the Registrable Securities on any securities exchange on which the same securities of

12

the Company are then listed and the fees and expenses of any person, including special experts, retained by the Company.

SECTION 6. Indemnification; Contribution.

(a) The Company agrees to indemnify and hold harmless the Initial Purchaser and each Holder of Registrable Securities and each person, if any, who controls the Initial Purchaser or any Holder of Registrable Securities within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included in any preliminary prospectus or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, provided that (subject to Section 6(d) below) any such settlement is effected with the prior written consent of the Company; and

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by the Initial Purchaser), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by the Initial Purchaser, such Holder of Registrable Securities (which also acknowledges the indemnity provisions herein) or any person, if any, who controls the Initial Purchaser or any such Holder of Registrable Securities expressly for use in the Registration Statement (or any amendment thereto), or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto); provided, further, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense (1) arising from an offer or sale of Registrable Securities occurring during a Deferral Period, if a Deferral Notice

13

was given to such Notice Holder in accordance with Section 8(b), or (2) if the Holder fails to deliver at or prior to the written confirmation of sale, the most recent Prospectus, as amended or supplemented, and such Prospectus, as amended or supplemented, would have corrected such untrue statement or omission or alleged untrue statement or omission of a material fact.

(b) In connection with any Shelf Registration in which a Holder, including, without limitation, the Initial Purchaser, of Registrable Securities is participating, in furnishing information relating to such Holder of Registrable Securities to the Company in writing expressly for use in such Registration Statement, any preliminary prospectus, the Prospectus or any amendments or supplements thereto, the Holders of such Registrable Securities agree, severally and not jointly, to indemnify and hold harmless the Initial Purchaser and each person, if any, who controls the Initial Purchaser within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and the Company, and each person, if any, who controls the Company within the meaning of either such Section, against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Holder of Registrable Securities (which also acknowledges the indemnity provisions herein) or any person, if any, who controls any such Holder of Registrable Securities expressly for use in the Registration Statement (or any amendment thereto) or such preliminary prospectus or the Prospectus (or any amendment or supplement thereto).

The Initial Purchaser agrees to indemnify and hold harmless the Company, the Holders of Registrable Securities, and each person, if any, who controls the Company or any Holder of Registrable Securities within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by the Initial Purchaser expressly for use in the Registration Statement (or any amendment thereto) or such preliminary prospectus or the Prospectus (or any amendment or supplement thereto).

(c) Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. The indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified

14

party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (a) the fees and expenses of more than one separate firm (in addition to any local counsel), whose fees must be reasonable, for the Initial Purchaser, Holders of Registrable Securities, and all persons, if any, who control the Initial Purchaser or Holders of Registrable Securities within the meaning of either
Section 15 of the Securities Act or Section 20 of the Exchange Act, collectively
(b) the fees and expenses of more than one separate firm (in addition to any local counsel), whose fees must be reasonable, for the Company and each person, if any, who controls the Company within the meaning of either such Section, and that all fees and expenses payable under (a) and (b) above shall be reimbursed as they are incurred. In the case of any such separate firm for the Initial Purchaser, Holders of Registrable Securities, and control persons of the Initial Purchaser and Holders of Registrable Securities, such firm shall be designated in writing by the Initial Purchaser. In the case of any such separate firm for the Company and control persons of the Company, such firm shall be designated in writing by the Company. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final non-appealable judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this
Section 6 (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement; provided, that an indemnifying party shall not be liable for any such settlement effected without its consent if such indemnifying party (1) reimburses such indemnified party in accordance with such request to the extent it considers such request to be reasonable and
(2) provides written notice to the indemnified party substantiating the unpaid balance as unreasonable, in each case prior to the date of such settlement.

15

(e) If the indemnification to which an indemnified party is entitled under this Section 6 is for any reason unavailable to or insufficient although applicable in accordance with its terms to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, in such proportion as is appropriate to reflect the relative fault of the indemnifying party or parties on the one hand and of the indemnified party on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative fault of the Company on the one hand and the Holders of the Registrable Securities or the Initial Purchaser on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Holder of the Registrable Securities or the Initial Purchaser and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 6(e) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 6(e). The aggregate amount of losses, liabilities, claims, damages, and expenses incurred by an indemnified party and referred to above in this Section 6(e) shall be deemed to include any out-of-pocket legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 6, neither the Holder of any Registrable Securities nor the Initial Purchaser, shall be required to indemnify or contribute any amount in excess of the amount by which the total price at which the Registrable Securities sold by such Holder of Registrable Securities or by the Initial Purchaser, as the case may be, and distributed to the public were offered to the public exceeds the amount of any damages that such Holder of Registrable Securities or the Initial Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 6(e), each person, if any, who controls the Initial Purchaser or any Holder of Registrable Securities within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Initial Purchaser or such Holder, and each person, if any, who controls the Company within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company, as the case may be.

16

SECTION 7. Information Requirements. The Company covenants that, if at any time before the end of the Effectiveness Period the Company is not subject to the reporting requirements of the Exchange Act, the Company will cooperate with any Holder of Registrable Securities and take such further reasonable action as any Holder of Registrable Securities may reasonably request in writing (including, without limitation, making such reasonable representations as any such Holder may reasonably request), all to the extent required from time to time to enable such Holder to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 and Rule 144A under the Securities Act and customarily taken in connection with sales pursuant to such exemptions. Upon the written request of any Holder of Registrable Securities, the Company shall deliver to such Holder a written statement as to whether the Company has complied with such filing requirements, unless such a statement has been included in the Company's most recent report required to be filed and filed pursuant to Section 13 or Section 15(d) of Exchange Act. Notwithstanding the foregoing, nothing in this Section 7 shall be deemed to require the Company to register any of its securities under any section of the Exchange Act.

SECTION 8. Miscellaneous; No Conflicting Agreements. The Company is not, as of the date hereof, a party to, nor shall the Company, on or after the date of this Agreement, enter into, any agreement with respect to its securities that conflicts with the rights granted to the Holders of Registrable Securities in this Agreement. The Company represents and warrants that the rights granted to the Holders of Registrable Securities hereunder do not in any way conflict with the rights granted to the holders of the Company's other issued and outstanding securities under any other agreements.

(a) Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the Company has obtained the written consent of Holders of a majority of the then outstanding Underlying Common Stock constituting Registrable Securities (with Holders of LYONs deemed to be the Holders, for purposes of this Section, of the number of outstanding shares of Underlying Common Stock into which such LYONs are or would be convertible or exchangeable as of the date on which such consent is requested). Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders of Registrable Securities whose securities are being sold pursuant to a Registration Statement and that does not directly or indirectly affect the rights of other Holders of Registrable Securities may be given by Holders of at least a majority of the Registrable Securities being sold by such Holders pursuant to such Registration Statement; provided, that the provisions of this sentence may not be amended, modified, or supplemented except in accordance with the provisions of the immediately preceding sentence. Each Holder of Registrable Securities outstanding at the time of any such amendment, modification, supplement, waiver or consent or thereafter shall be bound by any such amendment, modification, supplement, waiver or consent effected pursuant to this Section 8(a), whether or not any notice, writing or marking indicating such amendment, modification, supplement, waiver or consent appears on the Registrable Securities or is delivered to such Holder.

(b) Notices. All notices and other communications provided for or permitted hereunder shall be made in writing by hand delivery, by telecopier, by courier guaranteeing

17

overnight delivery or by first-class mail, return receipt requested, and shall be deemed given (i) when made, if made by hand delivery, (ii) upon confirmation, if made by telecopier, (iii) one (1) Business Day after being deposited with such courier, if made by overnight courier or (iv) on the date indicated on the notice of receipt, if made by first-class mail, to the parties as follows:

(w) if to a Holder of Registrable Securities that is not a Notice Holder, at the address for such Holder then appearing in the Registrar (as defined in the Indenture);

(x) if to a Notice Holder, at the most current address given by such Holder to the Company in a Notice and Questionnaire or any amendment thereto;

(y) if to the Company, to:

or to such other address as such person may have furnished to the other persons identified in this Section 8(c) in writing in accordance herewith.

(c) Approval of Holders. Whenever the consent or approval of Holders of a specified percentage of Registrable Securities is required hereunder, Registrable Securities held by the Company or its affiliates (as such term is defined in Rule 405 under the Securities Act) (other than the Initial Purchaser or subsequent Holders of Registrable Securities if such subsequent Holders are deemed to be such affiliates solely by reason of their holdings of such Registrable Securities) shall not be counted in determining whether such consent or approval was given by the Holders of such required percentage.

(d) Successors and Assigns. Any person who purchases any Registrable Securities from the Initial Purchaser shall be deemed, for purposes of this Agreement, to be an assignee of the Initial Purchaser. This Agreement shall inure to the benefit of and be binding upon the successors and assigns of each of the parties and shall inure to the benefit of and be binding upon each Holder of any Registrable Securities.

18

(e) Counterparts. This Agreement may be executed in any number of counterparts and by the parties hereto in separate counterparts, each of which when so executed shall be deemed to be original and all of which taken together shall constitute one and the same agreement.

(f) Headings. The headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning hereof.

(g) Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

(h) Severability. If any term, provision, covenant or restriction of this Agreement is held to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated thereby, and the parties hereto shall use their best efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction, it being intended that all of the rights and privileges of the parties shall be enforceable to the fullest extent permitted by law.

(i) Entire Agreement. This Agreement is intended by the parties as a final expression of their agreement and is intended to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein and the registration rights granted by the Company with respect to the Registrable Securities. Except as provided in the Purchase Agreement, there are no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein, with respect to the registration rights granted by the Company with respect to the Registrable Securities. This Agreement supersedes all prior agreements and undertakings among the parties solely with respect to such registration rights.

(j) Termination. This Agreement and the obligations of the parties hereunder shall terminate upon the end of the Effectiveness Period, except for any liabilities or obligations under Sections 4, 5 or 6 hereof and the obligations to make payments of and provide for Liquidated Damages under
Section 2(e) hereof to the extent such damages accrue prior to the end of the Effectiveness Period, each of which shall remain in effect in accordance with its terms.

Re: 3M Company Liquid Yield Option(TM) Notes due 2032 and common stock issuable upon conversion

Ladies and Gentlemen:

I am Assistant General Counsel of 3M Company, a Delaware corporation (the "Company"), and as such I have acted as counsel in connection with the registration of $639,000,000 aggregate principal amount of the Company's Liquid Yield Option(TM) Notes due 2032 (the "LYONs") and the shares of common stock issuable upon conversion of the LYONs (the "Common Stock" and, together with the LYONs, the "Securities") by the Company under the Securities Act of 1933, as amended (the "Act"), on Form S-3 to be filed with the Securities and Exchange Commission on the date hereof (the "Registration Statement"). Capitalized terms used herein but not otherwise defined shall have the meaning assigned to them in the Registration Statement.

In connection with the foregoing, I have examined, or am familiar with, originals, or copies, certified or otherwise, identified to my satisfaction, of such documents, corporate records and other instruments as I have deemed necessary for the purpose of this opinion. Based up such review of law and facts as I have deemed appropriate under the circumstances, I am of the opinion that:

(i) The LYONs have been duly authorized by all necessary corporate action of the Company and constitute legal, valid and binding obligations of the Company, enforceable against the Company in accordance with their terms and the terms of the Indenture, except as the enforcement thereof may be limited by (i) bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfers), reorganization, moratorium or other similar laws relating to or affecting enforcement of creditors' rights generally, or (ii) by general principles of equity (regardless of whether enforcement is considered in a proceeding in equity or at law).

(ii) The shares of Common Stock issuable upon conversion of the LYONs have been duly authorized and reserved for issuance upon such conversion by all necessary corporate action and such shares, when issued upon such conversion in accordance with the terms of the Indenture, will be legally issued and will be fully paid and non-assessable.

1

In rendering such opinions, I may rely as to matters of fact, to the extent I deem proper, on certificates of responsible officers of the Company and certificates or other written statements of officials of jurisdictions having custody of documents respecting the corporate existence or good standing of the Company. This opinion is limited to the Federal laws of the United States and the laws of the State of New York and the General Corporate Laws of the State of Delaware (including the statutory provisions and all applicable provisions of the Delaware Constitution and reported judicial decisions interpreting the General Corporate Laws of the State of Delaware).

I consent to the filing of this opinion by the Company as an exhibit to the Registration Statement and to the use of my name under the heading "Legal Matters" in the Registration Statement. In giving the foregoing consent, however, I do not admit that I come within the category of person whose consent is required under Section 7 of the Act or the rules and regulations of the Commission promulgated thereunder.

Sincerely yours,

Re: 3M Company Liquid Yield Option(TM) Notes due 2032

Ladies & Gentlemen:

I am tax counsel to 3M Company, a Delaware corporation (the "Company"), and have advised the Company in connection with the registration of $639,000,000 aggregate principal amount at maturity of the Company's Liquid Yield Option(TM) Notes due November 21, 2032 (the "Securities") by the Company under the Securities Act of 1933, as amended (the "Act"), on Form S-3, of which the preliminary Prospectus forms a part (the "Prospectus"), to be filed with the Securities and Exchange Commission on the date hereof (the "Registration Statement"). The Securities were issued pursuant to an Indenture, dated as of November 21, 2002 (the "Indenture"), between the Company and Citibank, N.A., as trustee.

As tax counsel to the Company, I have made such legal and factual examinations and inquiries and obtained such advice, assurances, and certificates as I have deemed necessary and advisable under the circumstances in order to render this opinion, including, but not limited to, an examination of originals or copies of the following:

(a) the Registration Statement and Prospectus;

(b) the Purchase Agreement, dated as of November 15, 2002 (the "Purchase Agreement"), between the Company and Merrill Lynch & Co., Merrill Lynch Pierce Fenner & Smith Incorporated (the "Initial Purchaser"), with respect to the issue and sale by the Company and the purchase by the Initial Purchaser of the Securities;

(c) the Indenture;

(d) the forms of the Securities, as attached as exhibits to the Indenture; and


(TM) Trademark of Merrill Lynch & Co., Inc.

(e) the Registration Rights Agreement, dated as of November 21, 2002, between the Company and the Initial Purchaser.

The term "Documents" as used in this opinion letter refers to the documents listed in paragraphs (b) through (e) above.

In my examinations, I have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of original and certified documents, and the conformity to original or certified documents of all copies submitted as conformed or reproduced copies. To the extent it may be relevant to the opinions expressed herein, I have assumed that parties to the Documents other than the Company have the power to enter into and perform such agreements and that such agreements have been duly authorized, executed, and delivered by such other parties and constitute legal, valid, and binding obligations of such other parties, enforceable against such parties in accordance with their terms, and that such parties will comply with all other obligations under the Documents and all laws applicable thereto.

On the basis of the foregoing, and in reliance thereon, and subject to the assumptions, qualifications, and limitations set forth herein, I am of the opinion that:

The Securities will be treated as indebtedness of the Company for United States federal income tax purposes that are subject to the regulations governing contingent payment debt instruments that are contained in Treasury Regulation section 1.1275-4(b); and the statements in the Prospectus under the caption "Certain United States Federal Income Tax Considerations", insofar as such statements constitute a summary of the United States federal tax laws referred to therein, accurately summarize in all material respects the United States federal tax laws referred to therein.

The opinions expressed herein are given as of the date hereof, and I undertake no obligation to supplement this letter if any applicable laws change after the date hereof or if I become aware of any facts that might change the opinions expressed herein after the date hereof or for any other reason. This opinion is provided to you as a legal opinion only and not as a guaranty or warranty of the matters discussed herein.

I consent to the filing of this opinion by the Company as an exhibit to the Registration Statement and to the use of my name under the captions " Certain United States Federal Income Tax Considerations"and "Legal Matters" in the Prospectus.
