UNDERWRITING AGREEMENT

Dated: May 30, 2001


Markel Corporation

Debt Securities

Underwriting Agreement

May 30, 2001

To the Representatives of the several
Underwriters named in the respective
Pricing Agreements hereinafter described.

Ladies and Gentlemen:

From time to time Markel Corporation, a Virginia corporation (the "Company"), proposes to enter into one or more Pricing Agreements (each a "Pricing Agreement") to be attached as Annex I hereto, subject to the terms and conditions stated herein and therein, to issue and sell to the firm or firms named in Schedule I to the applicable Pricing Agreement (such firm or firms constituting the "Underwriters" with respect to such Pricing Agreement and the securities specified therein) certain of its debt securities (the "Securities"), specified in Schedule II to such Pricing Agreement (with respect to such Pricing Agreement, the "Firm Securities"). If specified in such Pricing Agreement, the Company may grant to the Underwriters the right to purchase at their election an additional aggregate principal amount of debt securities, specified in such Pricing Agreement as provided in Section 3 hereof (the "Optional Securities").

The Firm Securities and the Optional Securities, if any, which the Underwriters elect to purchase pursuant to Section 3 hereof are herein collectively called the "Designated Securities."

The Designated Securities are to be issued pursuant to an indenture dated as of June 5, 2001 between the Company and The Chase Manhattan Bank as trustee (the "Trustee"), as amended by the first supplemental indenture thereto (the "Indenture"). The Designated Securities issued in book-entry form will be issued to Cede & Co., as nominee of the Depository Trust Company ("DTC") pursuant to a letter agreement, to be dated as of the Time of Delivery (as defined in Section 4 below), among the Company, the Trustee and DTC. The Designated Securities and the Indenture are more fully described in the Prospectus referred to below.

The terms and rights of any particular issuance of Designated Securities shall be as specified in the Pricing Agreement relating thereto.

1. Particular sales of Designated Securities may be made from time to time to the Underwriters of such Securities, for whom the firms designated as representatives of the Underwriters of such Securities in the Pricing Agreement relating thereto will act as representatives (the "Representatives"). The term "Representatives" also refers to a single firm acting as sole representative of the Underwriters and to Underwriters who act without any firm


being designated as their representative. This Underwriting Agreement shall not be construed as an obligation of the Company to sell any of the Securities or as an obligation of any of the Underwriters to purchase any of the Securities. The obligation of the Company to issue and sell any of the Securities and the obligation of any of the Underwriters to purchase any of the Securities shall be evidenced by the Pricing Agreement with respect to the Designated Securities specified therein. Each Pricing Agreement shall specify the aggregate principal amount of Firm Securities, the maximum principal amount of Optional Securities, if any, the initial public offering price of such Designated Securities or the manner of determining such price, the purchase price to the Underwriters of such Designated Securities, the names of the Underwriters of such Designated Securities, the names of the Representatives of such Underwriters, the number of such Designated Securities to be purchased by each Underwriter and the commission, if any, payable to the Underwriters with respect thereto and shall set forth the date, time and manner of delivery of such Designated Securities, and payment therefor. The Pricing Agreement shall also specify (to the extent not set forth in the registration statement and prospectus with respect thereto) the terms of such Designated Securities. A Pricing Agreement shall be in the form of an executed writing (which may be in counterparts), and may be evidenced by an exchange of telegraphic communications or any other rapid transmission device designed to produce a written record of communications transmitted. The obligations of the Underwriters under this Agreement and each Pricing Agreement shall be several and not joint.

2. (a) The Company represents and warrants to, and agrees with, each of the Underwriters that:

(i) A registration statement on Form S-3 (File No. 333-52544) as amended by Amendment No. 1 thereto (the "Registration Statement") in respect of the Securities has been filed with the Securities and Exchange Commission (the "Commission"); the Registration Statement and any post- effective amendment thereto, each in the form heretofore delivered or to be delivered to (i) the Representatives and (ii) excluding exhibits to the Registration Statement, but including all documents incorporated by reference in the prospectus included therein, to the Representatives for each of the other Underwriters, have been declared effective by the Commission in such form; the Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended (the "1934 Act"); other than a registration statement, if any, increasing the size of the offering (a "Rule 462(b) Registration Statement"), filed pursuant to Rule 462(b) under the Securities Act of 1933, as amended (the "Act"), which became effective upon filing, no other document with respect to the Registration Statement or document incorporated by reference therein has heretofore been filed, or transmitted for filing, with the Commission (other than prospectuses filed pursuant to Rule 424(b) of the rules and regulations of the Commission under the Act, each in the form heretofore delivered to the Representatives); and no stop order suspending the effectiveness of the Registration Statement, any post-effective amendment thereto or the Rule
462(b) Registration Statement, if any, has been issued and no proceeding for that purpose has been initiated or threatened by the Commission; the prospectus relating to the Securities, in the form in which it has most recently been filed, or transmitted for filing, with the Commission on or prior to the date of this Underwriting Agreement, is hereinafter called the "Prospectus"; any reference herein to the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to the applicable form under the Act, as of the

2

date of such Prospectus; any reference to any amendment or supplement to the Prospectus shall be deemed to refer to and include any documents filed after the date of such Prospectus, as the case may be, under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and incorporated by reference in such Prospectus; any reference to any amendment to the Registration Statement shall be deemed to refer to and include any annual report of the Company filed pursuant to Section 13(a) or 15(d) of the Exchange Act after the effective date of the Registration Statement; and any reference to the Prospectus as amended or supplemented shall be deemed to refer to the Prospectus as amended or supplemented in relation to the applicable Designated Securities in the form in which it is filed with the Commission pursuant to Rule 424(b) under the Act in accordance with Section 5(a) hereof, including any documents incorporated by reference therein as of the date of such filing);

(iii) The Registration Statement and the Prospectus conform, and any further amendments or supplements to the Registration Statement or the Prospectus will conform, in all material respects to the requirements of the Act and the rules and regulations of the Commission thereunder and do not and will not, as of the applicable effective date as to the Registration Statement and any amendment thereto and as of the applicable filing date as to the Prospectus and any amendment or supplement thereto, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; provided, however, that this representation and warranty shall not apply to any statements or omissions made in reliance upon and in conformity with information furnished in writing to the Company by an Underwriter of Designated Securities through the Representatives expressly for use in the Prospectus as amended or supplemented relating to such Securities;

3

(ii) any statute or any order, rule or regulation of any court or governmental agency or body having jurisdiction over the Company or any of its properties, except, in the case of clause (ii), for such violations as could not reasonably be expected, individually or in the aggregate, to have a Material Adverse Effect; and no consent, approval, authorization, order, registration or qualification of or with any such court or governmental agency or body is required for the issue and sale of the Firm Securities and the Optional Securities or the consummation by the Company of the transactions contemplated by this Agreement or any Pricing Agreement or any Over-allotment Option, except such as have been, or will have been prior to each Time of Delivery (as defined in Section 4 hereof), obtained under the Act, such consents, approvals, authorizations, registrations or qualifications as may be required under state securities or Blue Sky laws in connection with the purchase and distribution of the Securities by the Underwriters and such consents, approvals, authorizations, registrations or qualifications the failure to obtain which could not reasonably be expected to have a Material Adverse Effect;

3. Upon the execution of the Pricing Agreement applicable to any Designated Securities and authorization by the Representatives of the release of the Firm Securities, the several Underwriters propose to offer the Firm Securities for sale upon the terms and conditions set forth in the Prospectus as amended or supplemented.

The Company may specify in the Pricing Agreement applicable to any Designated Securities that the Company thereby grants to the Underwriters the right (an "Overallotment Option") to purchase at their election up to the maximum aggregate principal amount of Optional Securities set forth in such Pricing Agreement, on the terms set forth in the paragraph above, for the sole purpose of covering over-allotments in the sale of the Firm Securities. Any such election to purchase Optional Securities may be exercised by written notice from the Representatives to the Company, given within a period specified in the Pricing Agreement, setting forth the aggregate principal amount of Optional Securities to be purchased and the date on which such Optional Securities are to be delivered, as determined by the Representatives but in no event earlier than the First Time of Delivery (as defined in Section 4 hereof) or, unless the Representatives and the Company otherwise agree in writing, earlier than or later than the respective number of business days after the date of such notice set forth in such Pricing Agreement.

The aggregate principal amount of Optional Securities to be added to the aggregate principal amount of Firm Securities to be purchased by each Underwriter, as set forth in Schedule I to the Pricing Agreement applicable to such Designated Securities, shall be, in each

6

case, the aggregate principal amount of Optional Securities which the Company has been advised by the Representatives have been attributed to such Underwriter; provided that, if the Company has not been so advised, the aggregate principal amount of Optional Securities to be so added shall be, in each case, that proportion of Optional Securities which the aggregate principal amount of Firm Securities to be purchased by such Underwriter under such Pricing Agreement bears to the aggregate principal amount of Firm Securities. The total aggregate principal amount of Designated Securities to be purchased by all the Underwriters pursuant to such Pricing Agreement shall be the aggregate principal amount of Firm Securities set forth in Schedule I to such Pricing Agreement plus the aggregate principal amount of Optional Securities which the Underwriters elect to purchase.

4. Certificates for the Firm Securities and the Optional Securities to be purchased by each Underwriter pursuant to the Pricing Agreement relating thereto, in the form specified in such Pricing Agreement and in such authorized denominations and registered in such names as the Representatives may request upon at least forty-eight hours' prior notice to the Company, shall be delivered by or on behalf of the Company to the Representatives for the account of such Underwriter, against payment by such Underwriter or on its behalf of the purchase price therefor by wire transfer of Federal (same-day) funds to the account specified by the Company to the Representatives at least forty-eight hours in advance, as specified in such Pricing Agreement, (i) with respect to the Firm Securities, all in the manner and at the place and time and date specified in such Pricing Agreement or at such other place and time and date as the Representatives and the Company may agree upon in writing, such time and date being herein called the "First Time of Delivery" and (ii) with respect to the Optional Securities, if any, in the manner and at the time and date specified by the Representatives in the written notice given by the Representatives of the Underwriters' election to purchase such Optional Securities, or at such other time and date as the Representatives and the Company may agree upon in writing, such time and date, if not the First Time of Delivery, herein called the "Second Time of Delivery". Each such time and date for delivery is herein called a "Time of Delivery".

5. The Company agrees with each of the Underwriters of any Designated Securities:

(a) To prepare the Prospectus as amended and supplemented in relation to the applicable Designated Securities in a form approved by the Representatives and to file such Prospectus pursuant to Rule 424(b) under the Act not later than the Commission's close of business on the second business day following the execution and delivery of the Pricing Agreement relating to the applicable Designated Securities or, if applicable, such earlier time as may be required by Rule 424(b); to make no further amendment or any supplement to the Registration Statement or Prospectus as amended or supplemented after the date of the Pricing Agreement relating to such Designated Securities and prior to any Time of Delivery for such Designated Securities which shall be disapproved by the Representatives for such Designated Securities promptly after reasonable notice thereof; to advise the Representatives promptly of any such amendment or supplement after any Time of Delivery for such Designated Securities and furnish the Representatives with copies thereof; to file promptly all reports and any definitive proxy or information statements required to be filed by the Company with the Commission pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act for so long as the delivery of a

7

prospectus is required in connection with the offering or sale of such Designated Securities, and during such same period to advise the Representatives, promptly after it receives notice thereof, of the time when any amendment to the Registration Statement has been filed or becomes effective or any supplement to the Prospectus or any amended Prospectus has been filed with the Commission, of the issuance by the Commission of any stop order or of any order preventing or suspending the use of any prospectus relating to the Securities, of the suspension of the qualification of such Securities for offering or sale in any jurisdiction, of the initiation or threatening of any proceeding for any such purpose, or of any request by the Commission for the amending or supplementing of the Registration Statement or Prospectus or for additional information; and, in the event of the issuance of any such stop order or of any such order preventing or suspending the use of any prospectus relating to the Securities or suspending any such qualification, promptly to use its best efforts to obtain the withdrawal of such order;

(b) Promptly from time to time to take such action as the Representatives may reasonably request to qualify such Securities for offering and sale under the securities laws of such jurisdictions as the Representatives may request and to comply with such laws so as to permit the continuance of sales and dealings therein in such jurisdictions for as long as may be necessary to complete the distribution of such Securities, provided that in connection therewith the Company shall not be required to qualify as a foreign corporation or to file a general consent to service of process in any jurisdiction;

(c) Promptly as practicable after the date of the Pricing Agreement applicable to the Designated Securities and from time to time, to furnish the Underwriters with written and electronic copies of the Prospectus as amended or supplemented in New York City in such quantities as the Representatives may reasonably request, and, if the delivery of a prospectus is required at any time in connection with the offering or sale of the Securities and if at such time any event shall have occurred as a result of which the Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made when such Prospectus is delivered, not misleading, or, if for any other reason it shall be necessary during such same period to amend or supplement the Prospectus or to file under the Exchange Act any document incorporated by reference in the Prospectus in order to comply with the Act or the Exchange Act, to notify the Representatives and upon their request to file such document and to prepare and furnish without charge to each Underwriter and to any dealer in securities as many written and electronic copies as the Representatives may from time to time reasonably request of an amended Prospectus or a supplement to the Prospectus which will correct such statement or omission or effect such compliance;

(d) To make generally available to its security holders as soon as practicable, but in any event not later than eighteen months after the effective date of the Registration Statement (as defined in Rule 158(c) under the Act), an earnings statement of the Company and its subsidiaries (which need not be audited) complying with Section 11(a) of the Act and the rules and regulations of the Commission thereunder (including, at the option of the Company, Rule 158);

8

(e) During the period beginning from the date of the Pricing Agreement for such Designated Securities and continuing to and including 90 days after the date of the Prospectus, not to offer, sell, contract to sell or otherwise dispose of, except as provided hereunder, any securities of the Company that are substantially similar to the common shares of the Company, no par value ("Common Shares"), including but not limited to any securities that are convertible into or exchangeable for, or that represent the right to receive, Common Shares or any such substantially similar securities (other than pursuant to (i) employee stock purchase plans existing on, or (ii) employee stock option plans existing on, or (iii) the contingent value rights existing on, the date of the Pricing Agreement for such Designated Securities) without the prior written consent of the Representatives;

(f) To apply the net proceeds from the sale of the Designated Securities sold by the Company substantially in accordance with the description set forth in the Prospectus; and not to use any such net proceeds for reserves or payments relating to any insurance claims of Markel International Limited;

(g) If the Company elects to rely upon Rule 462(b), the Company shall file a Rule 462(b) Registration Statement with the Commission in compliance with Rule 462(b) by 10:00 P.M., Washington, D.C. time, on the date of this Agreement, and the Company shall at the time of filing either pay the Commission the filing fee for the Rule 462(b) Registration Statement or give irrevocable instructions for the payment of such fee pursuant to Rule 111(b) under the Act;

(h) To reserve and keep available at all times, free of preemptive or other similar rights, a sufficient number of Common Shares for the purpose of satisfying any obligations to issue Common Shares upon conversion of Designated Securities; and

(i) Upon request of any Underwriter, to furnish, or cause to be furnished, to such Underwriter an electronic version of the Company's trade names and corporate logo for use on the website, if any, operated by such Underwriter for the purpose of facilitating the on-line offering of the Securities (the "License"); provided, however, that the License shall be used solely for the purpose described above for a period not to exceed 120 days, is granted without any fee and may not be assigned or transferred.

6. The Company hereby covenants and agrees with the several Underwriters that the Company will pay or cause to be paid the following: (i) the fees, disbursements and expenses of the Company's counsel and accountants in connection with the registration of the Securities under the Act and all other expenses in connection with the preparation, printing and filing of the Registration Statement, any Preliminary Prospectus and the Prospectus and amendments and supplements thereto and the mailing and delivering of copies thereof to the Underwriters and dealers; (ii) the cost of printing or producing any Agreement among Underwriters, this Agreement, any Pricing Agreement, any Blue Sky Memorandum, closing documents (including compilations thereof) and any other documents in connection with the offering, purchase, sale and delivery of the Securities; (iii) all expenses in connection with the qualification of the Securities for offering and sale under state securities laws as provided in
Section 5(b) hereof, including the fees and disbursements of counsel for the Underwriters in

9

connection with such qualification and in connection with the Blue Sky survey(s); (iv) any filing fees incident to, and the fees and disbursements of counsel for the Underwriters in connection with, any required reviews by the National Association of Securities Dealers, Inc. of the terms of the sale of the Securities; (v) the cost of preparing certificates for the Securities; and (vi) the cost and charges of any transfer agent or registrar or dividend disbursing agent. It is understood, however, that, except as provided in this Section, and Sections 8 and 11 hereof, the Underwriters will pay all of their own costs and expenses, including the fees of their counsel, transfer taxes on resale of any of the Securities by them, and any advertising expenses connected with any offers they may make.

(ix) The statements set forth in the Prospectus under the caption "Description of LYONs", insofar as they purport to constitute a summary of the terms of the Designated Securities, under the caption "Description of Capital Stock", insofar as they purport to constitute a summary of the terms of the Securities, and under the captions "Plan of Distribution", insofar as they purport to describe the provisions of the laws and documents referred to therein, are accurate and complete in all material respects;

12

(xi) The documents incorporated by reference in the Prospectus as amended or supplemented (other than the financial statements and related schedules and other financial data therein, as to which such counsel need express no opinion), when they became effective or were filed with the Commission, as the case may be, complied as to form in all material respects with the requirements of the Act or the Exchange Act, as applicable, and the rules and regulations of the Commission thereunder;

(xii) The Registration Statement and the Prospectus as amended or supplemented, and any further amendments and supplements thereto made by the Company prior to such Time of Delivery (other than the financial statements and related schedules and other financial data therein, as to which such counsel need express no opinion), comply as to form in all material respects with the requirements of the Act and the rules and regulations thereunder. Such counsel shall also state that, although they are not passing upon, do not assume any responsibility for, and have not independently verified, the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Prospectus and any further amendments or supplements to the Prospectus made by the Company prior to such Time of Delivery, except for those referred to in the opinion in subsection
(viii) of this Section 7(c), in the course of their review and discussion of the contents of the Registration Statement and the Prospectus with certain officers and employees of the Company, nothing has come to their attention that causes them to believe that, as of its effective date, the Registration Statement or any further amendment thereto made by the Company prior to such Time of Delivery (other than the financial statements and related schedules and other financial data therein, as to which such counsel need make no statement) contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading or that, as of its date, the Prospectus as amended or supplemented or any further amendment or supplement thereto made by the Company prior to such Time of Delivery (other than the financial statements and related schedules and other financial data therein, as to which such counsel need make no statement) contained an untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading or that, as of such Time of Delivery, either the Registration Statement or the Prospectus as amended or supplemented or any further amendment or supplement thereto made by the Company prior to such Time of Delivery (other than the financial statements and related schedules and other financial data therein, as to which such counsel need make no statement) contains an untrue statement of a material fact or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; and they do not know of any amendment to the Registration Statement required to be filed or any contracts or other documents of a character required to be filed as an exhibit to the Registration Statement or required to be incorporated by reference into the Prospectus as amended or supplemented or required to be described in the

13

Registration Statement or the Prospectus as amended or supplemented which are not filed or incorporated by reference or described as required;

(xiii) The issuance of the shares of common stock upon conversion of the Designated Securities is not subject to (a) any preemptive rights under the Articles of Incorporation or By-laws of the Company or (b) to our knowledge, other similar rights of any securityholder of the Company.

(xiv) The Designated Securities will be treated as indebtedness for United States federal income tax purposes 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, are accurate and fairly summarize the United States federal tax laws referred to therein.

(d) On the date of the Pricing Agreement for such Designated Securities and at each Time of Delivery for such Designated Securities, the independent accountants of the Company who have certified the financial statements of the Company and its subsidiaries included or incorporated by reference in the Registration Statement shall have furnished to the Representatives a letter, dated the date of the Pricing Agreement, and a letter dated such Time of Delivery, respectively (a draft of the form of letter to be delivered on the date of the Pricing Agreement for such Designated Securities is attached as Annex II hereto), and with respect to such letter dated such Time of Delivery, as to such other matters as the Representatives may reasonably request and in form and substance satisfactory to the Representatives;

(e) (i) Neither the Company nor any of its Significant Subsidiaries shall have sustained since the date of the latest audited financial statements included or incorporated by reference in the Prospectus as amended prior to the date of the Pricing Agreement relating to the Designated Securities any loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree, otherwise than as set forth or contemplated in the Prospectus as amended prior to the date of the Pricing Agreement relating to the Designated Securities, and (ii) since the respective dates as of which information is given in the Prospectus as amended prior to the date of the Pricing Agreement relating to the Designated Securities there shall not have been any change in the capital stock (other than pursuant to (i) the Company's employee stock purchase plans existing on the date hereof, or (ii) the exercise of certain employee stock options existing on the date hereof), or long-term debt of the Company or any of its subsidiaries or any change, or any development involving a prospective change, in or affecting the general affairs, management, financial position, shareholders' equity or results of operations of the Company and its subsidiaries, otherwise than as set forth or contemplated in the Prospectus as amended prior to the date of the Pricing Agreement relating to the Designated Securities, the effect of which, in any such case described in clause (i) or (ii), is in the judgment of the Representatives so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of

14

the Designated Securities on the terms and in the manner contemplated in the Prospectus as amended relating to the Designated Securities;

(f) On or after the date of the Pricing Agreement relating to the Designated Securities no downgrading shall have occurred in the rating accorded the Company's debt securities or the Company's financial strength or claims paying ability by any "nationally recognized statistical rating organization", as that term is defined by the Commission for purposes of Rule 436(g)(2) under the Act, and on or after the date of the Pricing Agreement relating to the Designated Securities no such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any of the Company's debt securities or the Company's financial strength or claims paying ability;

(g) On or after the date of the Pricing Agreement relating to the Designated Securities there shall not have occurred any of the following:
(i) a suspension or material limitation in trading in securities generally on the New York Stock Exchange; (ii) a suspension or material limitation in trading in the Company's securities on the New York Stock Exchange; (iii) a general moratorium on commercial banking activities declared by either Federal or New York State authorities; or (iv) the outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency or war, if the effect of any such event specified in this clause (iv) in the judgment of the Representatives makes it impracticable or inadvisable to proceed with the public offering or the delivery of the Firm Securities or Optional Securities or both on the terms and in the manner contemplated in the Prospectus as first amended or supplemented relating to the Designated Securities;

(h) The Company shall have complied with the provisions of Section 5(c) hereof with respect to the furnishing of prospectuses on the New York Business Day next succeeding the date of the Pricing Agreement relating to such Designated Securities; and

(i) The Company shall have furnished or caused to be furnished to the Representatives at each Time of Delivery for the Designated Securities certificates of officers of the Company satisfactory to the Representatives as to the accuracy of the representations and warranties of the Company herein at and as of such Time of Delivery, as to the performance by the Company of all of its obligations hereunder to be performed at or prior to such Time of Delivery, as to the matters set forth in subsections (a) and
(e) of this Section and as to such other matters as the Representatives may reasonably request.

8. (a) The Company will indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Prospectus as amended or supplemented and any other prospectus relating to the Securities, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein

15

not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Prospectus as amended or supplemented and any other prospectus relating to the Securities, or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company by any Underwriter of Designated Securities through the Representatives expressly for use in the Prospectus as amended or supplemented relating to such Securities.

(b) Each Underwriter will indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Prospectus as amended or supplemented and any other prospectus relating to the Securities, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Prospectus as amended or supplemented and any other prospectus relating to the Securities, or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives expressly for use therein; and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred.

(c) Promptly after receipt by an indemnified party under subsection
(a), (b) or (c) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such

16

action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include any statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a), (b) or (c) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters of the Designated Securities on the other from the offering of the Designated Securities to which such loss, claim, damage or liability (or action in respect thereof) relates. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (d) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company one hand and the Underwriters of the Designated Securities on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and such Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from such offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by such Underwriters. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or such Underwriters on the other and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this subsection (e) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (e) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (e), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the applicable Designated Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter 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 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The obligations of the Underwriters of Designated Securities in this subsection (e) to contribute are several in proportion to their respective underwriting obligations with respect to such Securities and not joint.

17

(e) The obligations of the Company under this Section 8 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Act; and the obligations of the Underwriters under this Section 8 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company and to each person, if any, who controls the Company within the meaning of the Act.

9. (a) If any Underwriter shall default in its obligation to purchase the Firm Securities or Optional Securities which it has agreed to purchase under the Pricing Agreement relating to such Securities, the Representatives may in their discretion arrange for themselves or another party or other parties to purchase such Securities on the terms contained herein. If within thirty-six hours after such default by any Underwriter the Representatives do not arrange for the purchase of such Firm Securities or Optional Securities, as the case may be, then the Company shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to the Representatives to purchase such Securities on such terms. In the event that, within the respective prescribed period, the Representatives notify the Company that they have so arranged for the purchase of such Securities, or the Company notifies the Representatives that it has so arranged for the purchase of such Securities, the Representatives or the Company shall have the right to postpone a Time of Delivery for such Securities for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus as amended or supplemented, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in the opinion of the Representatives may thereby be made necessary. The term "Underwriter" as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to the Pricing Agreement with respect to such Designated Securities.

(b) If, after giving effect to any arrangements for the purchase of the Firm Securities or Optional Securities, as the case may be, of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate number of such Securities which remains unpurchased does not exceed one-eleventh of the aggregate number of the Firm Securities or Optional Securities, as the case may be, to be purchased at the respective Time of Delivery, then the Company shall have the right to require each non-defaulting Underwriter to purchase the number of Firm Securities or Optional Securities, as the case may be, which such Underwriter agreed to purchase under the Pricing Agreement relating to such Designated Securities and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of Firm Securities or Optional Securities, as the case may be, which such Underwriter agreed to purchase under such Pricing Agreement) of the Firm Securities or Optional Securities, as the case may be, of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Firm Securities or Optional Securities, as the case may be, of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate

18

number of Firm Securities or Optional Securities, as the case may be, which remains unpurchased exceeds one-eleventh of the aggregate number of the Firm Securities or Optional Securities, as the case may be, to be purchased at the respective Time of Delivery, as referred to in subsection (b) above, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Firm Securities or Optional Securities, as the case may be, of a defaulting Underwriter or Underwriters, then the Pricing Agreement relating to such Firm Securities or the Over- allotment Option relating to such Optional Securities, as the case may be, shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company and the Underwriters as provided in Section 6 hereof and the indemnity and contribution agreements in Section 8 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

10. The respective indemnities, agreements, representations, warranties and other statements of the Company and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter, or the Company, or any officer or director or controlling person of the Company and shall survive delivery of and payment for the Securities.

11. If any Pricing Agreement or Over-allotment Option shall be terminated pursuant to Section 9 hereof, the Company shall not then be under any liability to any Underwriter with respect to the Firm Securities or Optional Securities with respect to which such Pricing Agreement shall have been terminated except as provided in Sections 6 and 8 hereof; but, if for any other reason, Designated Securities are not delivered by or on behalf of the Company as provided herein, the Company will reimburse the Underwriters through the Representatives for all out-of-pocket expenses approved in writing by the Representatives, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of such Designated Securities, but the Company shall then be under no further liability to any Underwriter with respect to such Designated Securities except as provided in Sections 6 and 8 hereof.

12. In all dealings hereunder, the Representatives of the Underwriters of Designated Securities shall act on behalf of each of such Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by such Representatives jointly or by such of the Representatives, if any, as may be designated for such purpose in the Pricing Agreement.

All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail, telex or facsimile transmission to the address of the Representatives as set forth in the Pricing Agreement; and if to the Company shall be delivered or sent by mail, telex or facsimile transmission to the address of the Company set forth in the Registration Statement, Attention: Secretary; provided, however, that any notice to an Underwriter pursuant to Section 8(d) hereof shall be delivered or sent by mail, telex or facsimile transmission to such Underwriter at its address set forth in its Underwriters' Questionnaire, or telex constituting such Questionnaire, which address will be supplied to the

19

Company by the Representatives upon request. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

13. This Agreement and each Pricing Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters and the Company to the extent provided in Sections 8 and 10 hereof, the officers and directors of the Company and each person who controls the Company or any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement or any such Pricing Agreement. No purchaser of any of the Securities from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

14. Time shall be of the essence of each Pricing Agreement. As used herein, the term "business day" shall mean any day when the Commission's office in Washington, D.C. is open for business.

15. This Agreement and each Pricing Agreement shall be governed by and construed in accordance with the laws of the State of New York.

16. This Agreement and each Pricing Agreement may be executed by any one or more of the parties hereto and thereto in any number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument.

20

If the foregoing is in accordance with your understanding, please sign and return to us eight counterparts hereof.

Very truly yours,

Ladies and Gentlemen:

Markel Corporation, a Virginia corporation (the "Company"), proposes, subject to the terms and conditions stated herein and in the Underwriting Agreement, dated May 30, 2001 (the "Underwriting Agreement"), between the Company and Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated, to issue and sell to the Underwriter named in Schedule I hereto (the "Underwriter") the Securities specified in Schedule II hereto (the "Designated Securities," consisting of Firm Securities and any Optional Securities the Underwriter may elect to purchase). Each of the provisions of the Underwriting Agreement is incorporated herein by reference in its entirety, and shall be deemed to be a part of this Agreement to the same extent as if such provisions had been set forth in full herein; and each of the representations and warranties set forth therein shall be deemed to have been made at and as of the date of this Pricing Agreement, except that each representation and warranty which refers to the Prospectus in Section 2 of the Underwriting Agreement shall be deemed to be a representation or warranty as of the date of the Underwriting Agreement in relation to the Prospectus (as therein defined), and also a representation and warranty as of the date of this Pricing Agreement in relation to the Prospectus as amended or supplemented relating to the Designated Securities which are the subject of this Pricing Agreement. Each reference to the Representatives herein and in the provisions of the Underwriting Agreement so incorporated by reference shall be deemed to refer to you. Unless otherwise defined herein, terms defined in the Underwriting Agreement are used herein as therein defined. The Representatives designated to act on behalf of the Representatives and on behalf of each of the Underwriters of the Designated Securities pursuant to Section 12 of the Underwriting Agreement and the address of the Representatives referred to in such Section 12 are set forth in Schedule II hereto.

An amendment to the Registration Statement, or a supplement to the Prospectus, as the case may be, relating to the Designated Securities, in the form heretofore delivered to you is now proposed to be filed with the Commission.

Subject to the terms and conditions set forth herein and in the Underwriting Agreement incorporated herein by reference, (a) the Company agrees to issue and sell to the Underwriter, and the Underwriter agrees to purchase from the Company, at the time and place and at the purchase price to the Underwriter set forth in Schedule II hereto, the aggregate

1

principal amount of Firm Securities set forth opposite the name of the Underwriter in Schedule I hereto and, (b) in the event and to the extent that the Underwriter shall exercise the election to purchase Optional Securities, as provided below, the Company agrees to issue and sell to the Underwriter, and the Underwriter agrees to purchase from the Company at the purchase price to the Underwriter set forth in Schedule II hereto that portion of the aggregate principal amount at maturity of Optional Securities as to which such election shall have been exercised.

The Company hereby grants to the Underwriter the right to purchase at its election up to the aggregate principal amount at maturity of Optional Securities set forth opposite the name of such Underwriter in Schedule I hereto on the terms referred to in the paragraph above for the sole purpose of covering over-allotments in the sale of Firm Securities. Any such election to purchase Optional Securities may be exercised by written notice from the Representatives to the Company given within a period of 30 calendar days after the date of this Pricing Agreement, setting forth the aggregate principal amount at maturity of Optional Securities to be purchased and the date on which such Optional Securities are to be delivered, as determined by the Representatives, but in no event earlier than the First Time of Delivery or, unless the Representatives and the Company otherwise agree in writing, no earlier than two or later than ten business days after the date of such notice.

Each of Alan I. Kirshner, Anthony F. Markel, Steven A. Markel and Darrell D. Martin shall execute a "lock-up" agreement substantially in the form attached hereto as Schedule III, such execution by each person being a condition to the Underwriter's obligations hereunder, as though fully set forth in the
Section 7 of the Underwriting Agreement incorporated by reference herein.

If the foregoing is in accordance with your understanding, please sign and return to us eight counterparts hereof, and upon acceptance hereof by you, this letter and such acceptance hereof, including the provisions of the Underwriting Agreement incorporated herein by reference, shall constitute a binding agreement between the Underwriter and the Company.

SCHEDULE III - LOCK-UP AGREEMENT

June [ ], 2001

Merrill Lynch & Co.
Merrill Lynch, Pierce, Fenner & Smith
Incorporated
World Financial Center - North Tower
250 Vesey Street
New York, NY 10281

Re: Markel Corporation - Lock-Up Agreement

Ladies and Gentlemen:

The undersigned understands that you have entered into an Underwriting Agreement and Pricing Agreement constituting a part thereof (together, the "Underwriting Agreement") on behalf of the Underwriter named in Schedule I to the Pricing Agreement (the "Underwriter"), with Markel Corporation, a Virginia corporation (the "Company"), providing for a public offering of Liquid Yield Option(TM) Notes of the Company (the "LYONs"), convertible into common stock of the Company, no par value (the "Common Shares") pursuant to a Registration Statement on Form S-3 (File No. 333-52544) filed with the Securities and Exchange Commission (the "SEC").

In consideration of the agreement by the Underwriter to offer and sell the LYONs, and of other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the undersigned agrees that, during the period beginning from the date of the Prospectus Supplement covering the public offering of the LYONs and continuing to and including the date 90 days after the date of such final Prospectus Supplement, the undersigned will not offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose of any of the Common Shares of the Company, or any options or warrants to purchase any of the Common Shares of the Company, or any securities convertible into, exchangeable for or that represent the right to receive Common Shares of the Company, whether now owned or hereinafter acquired, owned directly by the undersigned (including holding as a custodian) or with respect to which the undersigned has pecuniary interest and investment control within the rules and regulations of the SEC (collectively the "Undersigned's Shares").

7

The foregoing restriction is expressly agreed to preclude the undersigned from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of the Undersigned's Shares even if such Undersigned's Shares would be disposed of by someone other than the undersigned. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put or call option) with respect to any of the Undersigned's Shares or with respect to any security that includes, relates to, or derives any significant part of its value from such Undersigned's Shares.

Notwithstanding the foregoing, the undersigned may transfer the Undersigned's Shares (i) as a bona fide gift or gifts, provided that the donee

or donees thereof agree to be bound in writing by the restrictions set forth herein, (ii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, provided that the trustee of the trust agrees to be bound in writing by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value, or (iii) with the prior written consent of the Underwriter, pledge the shares to the Company. In addition, notwithstanding any other provision of this Lock-Up Agreement, Alan I. Kirshner may transfer his Undersigned's Shares to any charitable trust (as such term is defined in the Internal Revenue Code) and Steven A. Markel may transfer his Undersigned's Shares, including any transfers effected prior to the date of the Prospectus Supplement covering the public offering of the LYONs, to any charitable trust (as such term is defined in the Internal Revenue Code) and no such charitable trusts shall be subject to the terms and restrictions of this Lock-Up Agreement. For purposes of this Lock-Up Agreement, "immediate family" shall mean any relationship by blood, marriage or adoption, not more remote than first cousin. In addition, notwithstanding the foregoing, if the undersigned is a corporation, the corporation may transfer the Common Shares of the Company to any wholly-owned subsidiary of such corporation; provided, however, that in any such case, it shall be a condition to the transfer that the transferee execute an agreement stating that the transferee is receiving and holding such Common Shares subject to the provisions of this Agreement and there shall be no further transfer of such Common Shares except in accordance with this Agreement, and provided further that any such transfer shall not involve a disposition for value. Except for encumbrances in effect as of the date of this letter, the undersigned now has, and, except as contemplated by clause (i), (ii), or (iii) above, for the duration of this Lock-Up Agreement will have, good and marketable title to the Undersigned's Shares, free and clear of all liens, encumbrances, and claims whatsoever. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company's transfer agent and registrar against the transfer of the Undersigned's Shares except in compliance with the foregoing restrictions.

8

The undersigned understands that the Company and the Underwriters are relying upon this Lock-Up Agreement in proceeding toward consummation of the offering. The undersigned further understands that this Lock-Up Agreement is irrevocable and shall be binding upon the undersigned's heirs, legal representatives, successors, and assigns.

Very truly yours,


Name:

ANNEX II

Pursuant to Section 7(d) of the Underwriting Agreement, the accountants shall furnish letters to the Underwriters to the effect that:

(i) They are independent certified public accountants with respect to the Company and its subsidiaries within the meaning of the Act and the applicable published rules and regulations thereunder;

(ii) In their opinion, the financial statements and any supplementary financial information and schedules (and, if applicable, financial forecasts and/or pro forma financial information) examined by them and included or incorporated by reference in the Registration Statement or the Prospectus comply as to form in all material respects with the applicable accounting requirements of the Act or the Exchange Act, as applicable, and the related published rules and regulations thereunder; and, if applicable, they have made a review in accordance with standards established by the American Institute of Certified Public Accountants of the consolidated interim financial statements, selected financial data, pro forma financial information, financial forecasts and/or condensed financial statements derived from audited financial statements of the Company for the periods specified in such letter, as indicated in their reports thereon, copies of which have been furnished to the representatives of the Underwriters (the "Representatives") and are attached hereto;

(iii) They have made a review in accordance with standards established by the American Institute of Certified Public Accountants of the unaudited condensed consolidated statements of income, consolidated balance sheets and consolidated statements of cash flows included in the Prospectus and/or included in the Company's quarterly reports on Form 10-Q incorporated by reference into the Prospectus as indicated in their reports thereon copies of which are attached hereto; and on the basis of specified procedures including inquiries of officials of the Company who have responsibility for financial and accounting matters regarding whether the unaudited condensed consolidated financial statements referred to in paragraph (vi)(A)(i) below comply as to form in all material respects with the applicable accounting requirements of the Exchange Act and the related published rules and regulations, nothing came to their attention that caused them to believe that the unaudited condensed consolidated financial statements do not comply as to form in all material respects with the applicable accounting requirements of the Exchange Act and the related published rules and regulations;

(iv) The unaudited selected financial information with respect to the consolidated results of operations and financial position of the Company for the five most recent fiscal years included in the Prospectus and included or incorporated by reference in Item 6 of the Company's Annual Report on Form 10-K for the most recent fiscal year agrees with the corresponding amounts (after restatement where applicable) in the audited consolidated financial statements for such five fiscal years which were included or incorporated by reference in the Company's Annual Reports on Form 10-K for such fiscal years;

1

(v) On the basis of limited procedures, not constituting an examination in accordance with generally accepted auditing standards, consisting of a reading of the unaudited financial statements and other information referred to below, a reading of the latest available interim financial statements of the Company and its subsidiaries, inspection of the minute books of the Company and its subsidiaries since the date of the latest audited financial statements included or incorporated by reference in the Prospectus, inquiries of officials of the Company and its subsidiaries responsible for financial and accounting matters and such other inquiries and procedures as may be specified in such letter, nothing came to their attention that caused them to believe that:

(A) (i) the unaudited condensed consolidated statements of income, consolidated balance sheets and consolidated statements of cash flows included in the Prospectus and/or included or incorporated by reference in the Company's Quarterly Reports on Form 10-Q incorporated by reference in the Prospectus do not comply as to form in all material respects with the applicable accounting requirements of the Exchange Act and the related published rules and regulations, or (ii) any material modifications should be made to the unaudited condensed consolidated statements of income, consolidated balance sheets and consolidated statements of cash flows included in the Prospectus or included in the Company's Quarterly Reports on Form 10-Q incorporated by reference in the Prospectus, for them to be in conformity with generally accepted accounting principles;

(B) any other unaudited income statement data and balance sheet items included in the Prospectus do not agree with the corresponding items in the unaudited consolidated financial statements from which such data and items were derived, and any such unaudited data and items were not determined on a basis substantially consistent with the basis for the corresponding amounts in the audited consolidated financial statements included or incorporated by reference in the Company's Annual Report on Form 10-K for the most recent fiscal year;

(C) the unaudited financial statements which were not included in the Prospectus but from which were derived the unaudited condensed financial statements referred to in clause (A) and any unaudited income statement data and balance sheet items included in the Prospectus and referred to in clause (B) were not determined on a basis substantially consistent with the basis for the audited financial statements included or incorporated by reference in the Company's Annual Report on Form 10-K for the most recent fiscal year; and

(D) any unaudited pro forma consolidated condensed financial statements included or incorporated by reference in the Prospectus do not comply as to form in all material respects with the applicable accounting requirements of the Act and the published rules and regulations thereunder or the pro forma adjustments have not been properly applied to the historical amounts in the compilation of those statements.

(E) as of a specified date not more than five days prior to the date of such letter, there have been any changes in the consolidated capital stock (other

2

than issuances of capital stock upon exercise of options and stock appreciation rights, upon earn-outs of performance shares and upon conversions of convertible securities, in each case which were outstanding on the date of the latest balance sheet included or incorporated by reference in the Prospectus) or any increase in the consolidated long-term debt of the Company and its subsidiaries, or any stockholders' equity or other items specified by the Representatives, or any increases in any items specified by the Representatives, in each case as compared with amounts shown in the latest balance sheet included or incorporated by reference in the Prospectus, except in each case for changes, increases or decreases which the Prospectus discloses have occurred or may occur or which are described in such letter; and

(F) for the period from the date of the latest financial statements included or incorporated by reference in the Prospectus to the specified date referred to in clause (E) there were any decreases in earned premiums or the total or per share amounts of consolidated net income or other items specified by the Representatives, or any increases in any items specified by the Representatives, in each case as compared with the comparable period of the preceding year and with any other period of corresponding length specified by the Representatives, except in each case for increases or decreases which the Prospectus discloses have occurred or may occur or which are described in such letter; and

(vi) In addition to the examination referred to in their report(s) included or incorporated by reference in the Prospectus and the limited procedures, inspection of minute books, inquiries and other procedures referred to in paragraphs (iii) and (vi) above, they have carried out certain specified procedures, not constituting an examination in accordance with generally accepted auditing standards, with respect to certain amounts, percentages and financial information specified by the Representatives which are derived from the general accounting records of the Company and its subsidiaries, which appear in the Prospectus (excluding documents incorporated by reference), or in Part II of, or in exhibits and schedules to, the Registration Statement specified by the Representatives or in documents incorporated by reference in the Prospectus specified by the Representatives, and have compared certain of such amounts, percentages and financial information with the accounting records of the Company and its subsidiaries and have found them to be in agreement.

All references in this Annex II to the Prospectus shall be deemed to refer to the Prospectus (including the documents incorporated by reference therein) as defined in the Underwriting Agreement as of the date of the letter delivered on the date of the Pricing Agreement for purposes of such letter and to the Prospectus as amended or supplemented (including the documents incorporated by reference therein) in relation to the applicable Designated Securities for purposes of the letter delivered at the Time of Delivery for such Designated Securities.

Section 103. Form of Documents Delivered to Trustee.

In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents.

Any certificate or opinion of an officer of the Company may be based, insofar as it relates to legal matters, upon an Opinion of Counsel, unless such officer knows, or in the exercise of reasonable care should know, that the opinion with respect to the matters upon which his certificate or opinion is based are erroneous. Any such Opinion of Counsel may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an officer or officers of the Company stating that the information with respect to such factual matters is in the possession of the Company unless such counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to such matters are erroneous.

18

Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture or any Security, they may, but need not, be consolidated and form one instrument.

Whenever, subsequent to the receipt by the Trustee of any Company Resolution, Officers' Certificate, Opinion of Counsel or other document or instrument, a clerical, typographical or other inadvertent or unintentional error or omission shall be discovered therein, a new document or instrument may be substituted therefor in corrected form with the same force and effect as if originally filed in the corrected form and, irrespective of the date or dates of the actual execution and/or delivery thereof, such substitute document or instrument shall be deemed to have been executed and/or delivered as of the date or dates required with respect to the document or instrument for which it is substituted. Anything in this Indenture to the contrary notwithstanding, if any such corrective document or instrument indicates that action has been taken by or at the request of the Company that could not have been taken had the original document or instrument not contained such error or omission, the action so taken shall not be invalidated or otherwise rendered ineffective but shall be and remain in full force and effect, except to the extent that such action was a result of willful misconduct or bad faith. Without limiting the generality of the foregoing, any Securities issued under the authority of such defective document or instrument shall nevertheless be the valid obligations of the Company entitled to the benefits of this Indenture equally and ratably with all other Outstanding Securities, except as aforesaid.

Section 104. Acts of Holders; Record Dates.

(1) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by or pursuant to this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing. Any request, demand, authorization, direction, notice, consent, waiver or other action provided in or pursuant to this Indenture to be given or taken by Holders of Securities of such series may, alternatively, be embodied in and evidenced by the record of Holders of Securities of such series voting in favor thereof, either in person or by proxies duly appointed in writing, at any meeting of Holders of Securities of such series duly called and held in accordance with the provisions of Article Fifteen or a combination of such instruments and any such record. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments or record or both are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments and any such record (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the "Act" of the Holders signing such instrument or instruments or so voting at any such meeting. Proof of execution of any such instrument or of a writing appointing any such agent, or of the holding by any Person of a Security, shall be sufficient for any purpose of this Indenture and (subject to
Section 315 of the Trust Indenture Act) conclusive in favor of the Trustee and the Company and any agent of the Trustee or the Company, if made in the manner provided in this Section. The record of any meeting of Holders of Securities shall be proved in the manner provided in Section 1506.

19

Without limiting the generality of this Section 104, unless otherwise provided in or pursuant to this Indenture, a Holder, including a U.S. Depositary that is a Holder of a Global Security, may make, give or take, by a proxy, or proxies, duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other Act provided in or pursuant to this Indenture or the Securities to be made, given or taken by Holders, and a U.S. Depositary that is a Holder of a Global Security may provide its proxy or proxies to the direct or indirect participants therein or the beneficial owners of interests in any such Global Security through such U.S. Depositary's standing instructions and customary practices.

(2) The fact and date of the execution by any Person of any such instrument or writing may be proved in any reasonable manner which the Trustee deems sufficient and in accordance with such reasonable rules as the Trustee may determine; and the Trustee may in any instance require further proof with respect to any of the matters referred to in this Section.

(3) The ownership, principal amount and serial numbers of Registered Securities held by any Person, and the date of the commencement and the date of the termination of holding the same, shall be proved by the Security Register.

(4) The ownership, principal amount and serial numbers of Bearer Securities held by any Person, and the date of the commencement and the date of the termination of holding the same, may be proved by the production of such Bearer Securities or by a certificate executed, as depositary, by any trust company, bank, banker or other depositary reasonably acceptable to the Company, wherever situated, if such certificate shall be deemed by the Company and the Trustee to be satisfactory, showing that at the date therein mentioned such Person had on deposit with such depositary, or exhibited to it, the Bearer Securities therein described; or such facts may be proved by the certificate or affidavit of the Person holding such Bearer Securities, if such certificate or affidavit is deemed by the Company and the Trustee to be satisfactory. The Trustee and the Company may assume that such ownership of any Bearer Security continues until (A) another certificate or affidavit bearing a later date issued in respect of the same Bearer Security is produced, or (B) such Bearer Security is produced to the Trustee by some other Person, or (C) such Bearer Security is surrendered in exchange for a Registered Security, or (D) such Bearer Security is no longer Outstanding. The ownership, principal amount and serial numbers of Bearer Securities held by the Person so executing such instrument or writing and the date of the commencement and the date of the termination of holding the same may also be proved in any other manner which the Company and the Trustee deem sufficient.

(5) Any request, demand, authorization, direction, notice, consent, waiver or other Act by 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 or suffered to be done by the Trustee, any Security Registrar, any Paying Agent or the Company in reliance thereon, whether or not notation of such Act is made upon such Security.

The Company may set any day as a record date for the purpose of determining the Holders of Outstanding Registered Securities of any series entitled to give, make or take any request,

20

demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders of Securities of such series; provided that the Company may not set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or making of any notice, declaration, request or direction referred to in the next paragraph. If any record date is set pursuant to this paragraph, the Holders of Outstanding Registered Securities of the relevant series on such record date, and no other Holders, shall be entitled to take or revoke the relevant action, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Company from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be canceled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Trustee in writing and to each Holder of Securities of the relevant series in the manner set forth in
Section 106.

The Trustee may set any day as a record date for the purpose of determining the Holders of Outstanding Registered Securities of any series entitled to join in the giving or making of (i) any Notice of Default, (ii) any declaration of acceleration referred to in Section 502, (iii) any request to institute proceedings referred to in Section 507(2) or (4) any direction referred to in
Section 512, in each case with respect to Securities of such series. If any record date is set pursuant to this paragraph, the Holders of Outstanding Registered Securities of such series on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction or to revoke the same, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be canceled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the Company's expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be sent to the Company in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 106.

With respect to any record date set pursuant to this Section, the party hereto that sets such record dates may designate any day as the "Expiration Date" and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the other party hereto in writing, and

21

to each Holder of Registered Securities of the relevant series in the manner set forth in Section 106, on or prior to the existing Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to this Section, the party hereto that sets such record date shall be deemed to have initially designated the 180th day after such record date as the Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be later than the 180th day after the applicable record date.

Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Security may do so with regard to all or any part of the principal amount of such Security or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such principal amount.

Section 105. Notices, Etc. To Trustee and Company.

Any request, demand, authorization, direction, notice, consent, waiver or other Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with,

Institutional Trust Services, or

(2) the Company by the Trustee or any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the Company addressed to the attention of its Treasurer at the address of its principal office specified in the first paragraph of this instrument or at any other address previously furnished in writing to the Trustee by the Company.

Section 106. Notice to Holders of Securities; Waiver.

Except as otherwise expressly provided in or pursuant to this Indenture, where this Indenture provides for notice to Holders of Securities of any event,

(2) such notice shall be sufficiently given to Holders of Bearer Securities, if any, if published in an Authorized Newspaper in The City of New York and, if such Securities are then listed on any stock exchange outside the United States, in an Authorized Newspaper in such city as the Company shall advise the Trustee that such stock exchange so requires, on a Business Day at least twice, the first such publication to be

22

not earlier than the earliest date and the second such publication not later than the latest date prescribed for the giving of such notice.

In any case where notice to Holders of Registered Securities is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder of a Registered Security shall affect the sufficiency of such notice with respect to other Holders of Registered Securities or the sufficiency of any notice to Holders of Bearer Securities given as provided herein. Any notice which is mailed in the manner herein provided shall be conclusively presumed to have been duly given or provided. In the case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

In case by reason of the suspension of publication of any Authorized Newspaper or Authorized Newspapers or by reason of any other cause it shall be impracticable to publish any notice to Holders of Bearer Securities as provided above, then such notification to Holders of Bearer Securities as shall be given with the approval of the Trustee shall constitute sufficient notice to such Holders for every purpose hereunder. Neither failure to give notice by publication to Holders of Bearer Securities as provided above, nor any defect in any notice so published, shall affect the sufficiency of any notice mailed to Holders of Registered Securities as provided above.

Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders of Securities shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

Section 107. Language of Notices.

Any request, demand, authorization, direction, notice, consent, election or waiver required or permitted under this Indenture shall be in the English language, except that, if the Company so elects, any published notice may be in an official language of the country of publication.

Section 108. Conflict with Trust Indenture Act.

If any provision hereof limits, qualifies or conflicts with any duties under any required provision of the Trust Indenture Act imposed hereon by
Section 318(c) thereof, such required provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act which may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be.

the Securities of this series, the Holders of not less than a majority in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed or provided for herein.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Securities of this series are issuable only in registered form without coupons in denominations of $1,000 and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series having the same Stated Maturity and of like tenor of any authorized denominations as requested by the Holder upon surrender of the Note or Notes to be exchanged at the office or agency of the Company.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this 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 this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

All terms used in this Security that are defined in the Indenture shall have the meanings assigned to them in the Indenture.

Section 204. Securities in Global Form.

30

Unless otherwise provided in or pursuant to this Indenture or any Securities, the Securities shall not be issuable in global form. If Securities of a series shall be issuable in temporary or permanent global form, any such Security may provide that it or any number of such Securities shall represent the aggregate amount of all Outstanding Securities of such series (or such lesser amount as is permitted by the terms thereof) from time to time endorsed thereon and may also provide that the aggregate amount of Outstanding Securities represented thereby may from time to time be increased or reduced to reflect exchanges. Any endorsement of any Security in global form to reflect the amount, or any increase or decrease in the amount, or changes in the rights of Holders, of Outstanding Securities represented thereby shall be made in such manner and by such Person or Persons as shall be specified therein or in the Company Order to be delivered pursuant to Section 303 or 304 with respect thereto. Subject to the provisions of Section 303 and, if applicable, Section 304, the Trustee shall deliver and redeliver any Security in permanent global form in the manner and upon instructions given by the Person or Persons specified therein or in the applicable Company Order. If a Company Order pursuant to Section 303 or 304 has been, or simultaneously is, delivered, any instructions by the Company with respect to a Security in global form shall be in writing but need not be accompanied by or contained in an Officers' Certificate and need not be accompanied by an Opinion of Counsel.

Notwithstanding the provisions of Section 307, unless otherwise specified in or pursuant to this Indenture or any Securities, payment of principal of, any premium and interest on, and any Additional Amounts in respect of any Security in temporary or permanent global form shall be made to the Person or Persons specified therein.

Notwithstanding the provisions of Section 308 and except as provided in the preceding paragraph, the Company, the Trustee and any agent of the Company and the Trustee shall treat as the Holder of such principal amount of Outstanding Securities represented by a Global Security in the case of a Global Security in registered form, the Holder of such Global Security in registered form.

Section 205. Form of Legend for Global Securities.

Unless otherwise specified as contemplated by Section 301 for the Securities evidenced thereby, every Global Security authenticated and delivered hereunder shall bear a legend in substantially the following form:

THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITARY OR A NOMINEE THEREOF. THIS SECURITY MAY NOT BE EXCHANGED IN WHOLE OR IN PART FOR A SECURITY REGISTERED, AND NO TRANSFER OF THIS SECURITY IN WHOLE OR IN PART MAY BE REGISTERED, IN THE NAME OF ANY PERSON OTHER THAN SUCH DEPOSITARY OR A NOMINEE THEREOF, EXCEPT IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE.

Section 206. Form of Trustee's Certificate of Authentication.

Subject to Section 612, the Trustee's certificate of authentication shall be in substantially the following form:

Section 207. Securities Repayable at the Option of Holders.

If the Company shall establish pursuant to Section 301 that the Securities of a particular series are to be repaid before their Stated Maturity at the option of Holders thereof, then the face of such Securities may indicate the applicable Repayment Date(s) and Repayment Price(s), and such Securities may include the following provisions:

If so indicated on the face of this Security, the Company may be required to repurchase this Security at the option of the Holder, in whole or in part, on the Repayment Date(s) and at the applicable Repayment Price(s) so indicated on the face hereof, plus accrued interest, if any, to the applicable Repayment Date. On or before the applicable Repayment Date, the Company shall deposit with the Trustee money sufficient to pay the applicable Repayment Price and any interest accrued on the portion of this Security to be tendered for repayment. On and after such Repayment Date, interest will cease to accrue on this Security or any portion hereof tendered for repayment.

The repayment option may be exercised by the Holder of this Security for less than the entire principal amount hereof, but in that event, the principal amount hereof remaining outstanding after repayment must be in an authorized denomination. In the event of repurchase of this Security in part only, a new Security or Securities of this series and of like tenor for the unpurchased portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

In order for this Security to be repaid, the Trustee must receive at least 30 days but not more than 60 days prior to the Repayment Date (i) this Security with the form entitled "Option to Elect Repayment" attached to this Security duly completed or (ii) a facsimile transmission or a letter from a member of a national securities exchange or the National Association of Securities Dealers, Inc. or a commercial bank or trust company in the United States setting forth the name of the Holder of this Security, the principal amount of this Security, the principal amount of this Security to be repaid, the certificate number or a description of the tenor and terms of this Security, a statement that the option to elect repayment is being exercised thereby, and a guarantee that this Security to be repaid, together with the duly completed form entitled "Option to Elect Repayment" attached to this Security, will be received by the Trustee not later than the fifth Business Day after the date of such facsimile transmission or letter; however, such facsimile

32

transmission or letter shall only be effective if this Security and duly completed form are received by the Trustee by such fifth Business Day. Such notice, once given, will be irrevocable unless waived by the Company.

Unless otherwise indicated on the face hereof, this Security will not be subject to repayment at the option of the Holder.

36

denomination and the rate of interest, or method of determining the rate of interest, if any, Maturity, and the date from which interest, if any, shall accrue and except as may otherwise be provided by the Company in or pursuant to the Company Resolution and set forth in, or determined in the manner provided, in the Officers' Certificate or in any indenture or indentures supplemental hereto pertaining to such series of Securities.

Unless otherwise provided in or pursuant to this Indenture, the principal of, any premium and interest on and any Additional Amounts with respect to the Securities shall be payable in Dollars. Unless otherwise provided in or pursuant to this Indenture, Registered Securities denominated in Dollars shall be issuable in registered form without Coupons in denominations of $1,000 and any integral multiple thereof, and the Bearer Securities denominated in Dollars shall be issuable in the denomination of $5,000. Securities not denominated in Dollars shall be issuable in such denominations as are established with respect to such Securities in or pursuant to this Indenture.

Section 303. Execution, Authentication, Delivery and Dating.

Securities shall be executed on behalf of the Company by any Officer. Coupons shall be executed on behalf of the Company by the Corporate Secretary or one of the Assistant Corporate Secretaries of the Company. The signature of such Officer on the Securities or any Coupons appertaining thereto may be manual or facsimile.

Securities and any Coupons appertaining thereto bearing the manual or facsimile signature of an individual who was at any time a proper Officer of the Company shall bind the Company, notwithstanding that such individual ceased to hold such office prior to the authentication and delivery of such Securities or did not hold such office at the date of such Securities or Coupons.

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities, together with any Coupons appertaining thereto, executed by the

37

Company, to the Trustee for authentication and, provided that the Company Resolution and Officers' Certificate or supplemental indenture or indentures with respect to such Securities referred to in Section 301 and a Company Order for the authentication and delivery of such Securities have been delivered to the Trustee, the Trustee in accordance with the Company Order and subject to the provisions hereof and of such Securities shall authenticate and deliver such Securities; provided, however, that in the case of Securities offered in a Periodic Offering, the Trustee shall authenticate and deliver such Securities from time to time in accordance with such other procedures (including, without limitation, the receipt by the Trustee of oral or electronic instructions from the Company or its duly authorized agents, promptly confirmed in writing) acceptable to the Trustee as may be specified by or pursuant to a Company Order delivered to the Trustee prior to the time of the first authentication of Securities of such series. If the form or terms of the Securities of the series have been established by or pursuant to one or more Company Resolutions as permitted by Sections 201 and 301, in authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities and any Coupons appertaining thereto, the Trustee shall be entitled to receive, and (subject to Sections 315(a) through 315(d) of the Trust Indenture Act) shall be fully protected in relying upon,

(1) an Opinion of Counsel to the effect that:

(a) the form or forms and terms, or if all Securities of such series are not to be issued at one time, the manner of determining the terms of such Securities and Coupons, if any, have been established in conformity with the provisions of this Indenture;

(b) all conditions precedent provided for in this Indenture to the authentication and delivery of such Securities and Coupons, if any, appertaining thereto have been complied with and that such Securities, and Coupons, when completed by appropriate insertions, executed by a duly authorized Officer of the Company, and delivered by a duly authorized Officer of the Company to the Trustee for authentication pursuant to this Indenture, and authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute legally valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, subject to bankruptcy, insolvency, reorganization, moratorium, arrangement, fraudulent conveyance, fraudulent transfer or other similar laws relating to or affecting creditors' rights generally, and subject to general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law); and

(c) this Indenture has been qualified under the Trust Indenture Act; and

(2) an Officers' Certificate stating that, to the best knowledge of the Persons executing such certificate, no event which is, or after notice or lapse of time would become, an Event of Default with respect to any of the Securities shall have occurred and be continuing.

38

If all the Securities of any series are not to be issued at one time, it shall not be necessary to deliver an Opinion of Counsel at the time of issuance of each Security, but such opinion shall be delivered at or before the time of issuance of the first Security of such series. After any such first delivery, any separate request by the Company that the Trustee authenticate Securities of such series for original issue will be deemed to be a certification by the Company that all conditions precedent provided for in this Indenture relating to authentication and delivery of such Securities continue to have been complied with.

The Trustee shall not be required to authenticate or to cause an Authenticating Agent to authenticate any Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee's own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee or if the Trustee, being advised by counsel, determines that such action may not lawfully be taken.

With respect to Securities of a series offered in a Periodic Offering, the Trustee may rely, as to the authorization by the Company of any of such Securities, the form and terms thereof and the legality, validity, binding effect and enforceability thereof, upon the Opinion of Counsel and the other documents delivered pursuant to Sections 201 and 301 and this Section, as applicable, in connection with the first authentication of Securities of such series.

Each Registered Security shall be dated the date of its authentication. Each Bearer Security and any temporary Bearer Security in global form shall be dated as of the date specified in or pursuant to this Indenture.

No Security or Coupon appertaining thereto 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 in Section 206 or 612 executed by or on behalf of the Trustee or by the Authenticating Agent by the manual signature of one of its authorized officers. Such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. Except as permitted by Section 306 or 307, the Trustee shall not authenticate and deliver any Bearer Security unless all Coupons appertaining thereto then matured have been detached and canceled.

Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 309, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture.

Section 304. Temporary Securities.

Pending the preparation of definitive Securities, the Company may execute and deliver to the Trustee and, upon Company Order, the Trustee shall authenticate and deliver, in the manner provided in Section 303, temporary Securities in lieu thereof which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially

39

of the tenor of the definitive Securities in lieu of which they are issued, in registered form or, if authorized in or pursuant to this Indenture, in bearer form with one or more Coupons or without Coupons and with such appropriate insertions, omissions, substitutions and other variations as the officers of the Company executing such Securities may determine, as conclusively evidenced by their execution of such Securities. Such temporary Securities may be in global form.

Except in the case of temporary Securities in global form, which shall be exchanged in accordance with the provisions thereof, if temporary Securities are issued, the Company shall cause definitive Securities to be prepared without unreasonable delay. After the preparation of definitive Securities of the same series and containing terms and provisions that are identical to those of any temporary Securities, such temporary Securities shall be exchangeable for such definitive Securities upon surrender of such temporary Securities at an Office or Agency for such Securities, without charge to any Holder thereof. Upon surrender for cancellation of any one or more temporary Securities (accompanied by any unmatured Coupons appertaining thereto), the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Securities of authorized denominations of the same series and containing identical terms and provisions; provided, however, that no definitive Bearer Security, except as provided in or pursuant to this Indenture, shall be delivered in exchange for a temporary Registered Security; and provided, further, that a definitive Bearer Security shall be delivered in exchange for a temporary Bearer Security only in compliance with the conditions set forth in or pursuant to this Indenture. Unless otherwise provided in or pursuant to this Indenture with respect to a temporary Global Security, until so exchanged the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series.

Section 305. Registration, Transfer and Exchange.

With respect to the Registered Securities of each series, if any, the Company shall cause to be kept a register (each such register being herein sometimes referred to as the "Security Register") at an Office or Agency for such series in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of the Registered Securities of such series and of transfers of the Registered Securities of such series. Such Office or Agency shall be the "Security Registrar" for that series of Securities. Unless otherwise specified in or pursuant to this Indenture or the Securities, the Trustee shall be the initial Security Registrar for each series of Securities. The Company shall have the right to remove and replace from time to time the Security Registrar for any series of Securities; provided that no such removal or replacement shall be effective until a successor Security Registrar with respect to such series of Securities shall have been appointed by the Company and shall have accepted such appointment. In the event that the Trustee shall not be or shall cease to be Security Registrar with respect to a series of Securities, it shall have the right to examine the Security Register for such series at all reasonable times. There shall be only one Security Register for each series of Securities.

Upon surrender for registration of transfer of any Registered Security of any series at any Office or Agency for such series, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Registered

40

Securities of the same series denominated as authorized in or pursuant to this Indenture, of a like aggregate principal amount bearing a number not contemporaneously outstanding and containing identical terms and provisions.

At the option of the Holder, Registered Securities of any series may be exchanged for other Registered Securities of the same series containing identical terms and provisions, in any authorized denominations, and of a like aggregate principal amount, upon surrender of the Securities to be exchanged at any Office or Agency for such series. Whenever any Registered Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Registered Securities which the Holder making the exchange is entitled to receive.

If provided in or pursuant to this Indenture, with respect to Securities of any series, at the option of the Holder, Bearer Securities of such series may be exchanged for Registered Securities of such series containing identical terms, denominated as authorized in or pursuant to this Indenture and in the same aggregate principal amount, upon surrender of the Bearer Securities to be exchanged at any Office or Agency for such series, with all unmatured Coupons and all matured Coupons in default thereto appertaining. If the Holder of a Bearer Security is unable to produce any such unmatured Coupon or Coupons or matured Coupon or Coupons in default, such exchange may be effected if the Bearer Securities are accompanied by payment in funds acceptable to the Company and the Trustee in an amount equal to the face amount of such missing Coupon or Coupons, or the surrender of such missing Coupon or Coupons may be waived by the Company and the Trustee if there is furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Bearer Security shall surrender to any Paying Agent any such missing Coupon in respect of which such a payment shall have been made, such Holder shall be entitled to receive the amount of such payment; provided, however, that, except as otherwise provided in Section 1002, interest represented by Coupons shall be payable only upon presentation and surrender of those Coupons at an Office or Agency for such series located outside the United States. Notwithstanding the foregoing, in case a Bearer Security of any series is surrendered at any such Office or Agency for such series in exchange for a Registered Security of such series and like tenor after the close of business at such Office or Agency on (i) any Regular Record Date and before the opening of business at such Office or Agency on the relevant Interest Payment Date, or (ii) any Special Record Date and before the opening of business at such Office or Agency on the related date for payment of Defaulted Interest, such Bearer Security shall be surrendered without the Coupon relating to such Interest Payment Date or proposed date of payment, as the case may be (or, if such Coupon is so surrendered with such Bearer Security, such Coupon shall be returned to the Person so surrendering the Bearer Security), and interest or Defaulted Interest, as the case may be, shall not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of the Registered Security issued in exchange for such Bearer Security, but shall be payable only to the Holder of such Coupon when due in accordance with the provisions of this Indenture.

If provided in or pursuant to this Indenture with respect to Securities of any series, at the option of the Holder, Registered Securities of such series may be exchanged for Bearer Securities

41

upon such terms and conditions as may be provided in or pursuant to this Indenture with respect to such series.

Whenever any Securities are surrendered for exchange as contemplated by the immediately preceding two paragraphs, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive.

Notwithstanding the foregoing, except as otherwise provided in or pursuant to this Indenture, any Global Security shall be exchangeable for definitive Securities only if (i) the Depositary is at any time unwilling, unable or ineligible to continue as Depositary and a successor depositary is not appointed by the Company within 90 days of the date the Company is so informed in writing,
(ii) the Company executes and delivers to the Trustee a Company Order to the effect that such Global Security shall be so exchangeable, or (iii) an Event of Default has occurred and is continuing with respect to the Securities. If the beneficial owners of interests in a Global Security are entitled to exchange such interests for definitive Securities as the result of an event described in clause (i), (ii) or (iii) of the preceding sentence, then without unnecessary delay but in any event not later than the earliest date on which such interests may be so exchanged, the Company shall deliver to the Trustee definitive Securities in such form and denominations as are required by or pursuant to this Indenture, and of the same series, containing identical terms and in aggregate principal amount equal to the principal amount of such Global Security, executed by the Company. On or after the earliest date on which such interests may be so exchanged, such Global Security shall be surrendered from time to time by the U.S. Depositary or such other Depositary as shall be specified in the Company Order with respect thereto, and in accordance with instructions given to the Trustee and the U.S. Depositary or such other Depositary, as the case may be (which instructions shall be in writing but need not be contained in or accompanied by an Officers' Certificate or be accompanied by an Opinion of Counsel), as shall be specified in the Company Order with respect thereto to the Trustee, as the Company's agent for such purpose, to be exchanged, in whole or in part, for definitive Securities as described above without charge. The Trustee shall authenticate and make available for delivery, in exchange for each portion of such surrendered Global Security, a like aggregate principal amount of definitive Securities of the same series of authorized denominations and of like tenor as the portion of such Global Security to be exchanged, which (unless such Securities are not issuable both as Bearer Securities and as Registered Securities, in which case the definitive Securities exchanged for the Global Security shall be issuable only in the form in which the Securities are issuable, as provided in or pursuant to this Indenture) shall be in the form of Bearer Securities or Registered Securities, or any combination thereof, as shall be specified by the beneficial owner thereof, but subject to the satisfaction of any certification or other requirements to the issuance of Bearer Securities; provided, however, that no such exchanges may occur during a period beginning at the opening of business 15 days before any selection of Securities of the same series to be redeemed and ending on the relevant Redemption Date; and provided, further, that (unless otherwise provided in or pursuant to this Indenture) no Bearer Security delivered in exchange for a portion of a Global Security shall be mailed or otherwise delivered to any location in the United States. Promptly following any such exchange in part, such Global Security shall be returned by the Trustee to such Depositary or the U.S. Depositary, as the case may be, or such other Depositary or U.S. Depositary referred to above in accordance with the instructions of the Company referred to

42

above. If a Registered Security is issued in exchange for any portion of a Global Security after the close of business at the Office or Agency for such Security where such exchange occurs on or after (i) any Regular Record Date for such Security and before the opening of business at such Office or Agency on the next Interest Payment Date, or (ii) any Special Record Date for such Security and before the opening of business at such Office or Agency on the related proposed date for payment of interest or Defaulted Interest, as the case may be, interest shall not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such Registered Security, but shall be payable on such Interest Payment Date or proposed date for payment, as the case may be, only to the Person to whom interest in respect of such portion of such Global Security shall be payable in accordance with the provisions of this Indenture.

All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company evidencing the same debt and entitling the Holders thereof to the same benefits under this Indenture as the Securities surrendered upon such registration of transfer or exchange.

Every Registered Security presented or surrendered for registration of transfer or for exchange or redemption shall (if so required by the Company or the Security Registrar for such Security) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar for such Security duly executed by the Holder thereof or his attorney duly authorized in writing.

No service charge shall be made for any registration of transfer or exchange, or redemption of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge and any other expenses (including fees and expenses of the Trustee) that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 304, 905 or 1107, upon repayment in part of any Registered Security pursuant to Article Thirteen, or upon surrender in part of any Registered Security for conversion or exchange into Capital Stock or other securities pursuant to its terms, in each case not involving any transfer.

Except as otherwise provided in or pursuant to this Indenture, the Company shall not be required (i) to issue, register the transfer of or exchange any Securities during a period beginning at the opening of business 15 days before the day of the selection for redemption of Securities of like tenor and the same series under Section 1103 and ending at the close of business on the day of such selection, or (ii) to register the transfer of or exchange any Registered Security so selected for redemption in whole or in part, except in the case of any Security to be redeemed in part, the portion thereof not to be redeemed, or
(iii) to exchange any Bearer Security so selected for redemption except, to the extent provided with respect to such Bearer Security, that such Bearer Security may be exchanged for a Registered Security of like tenor and the same series, provided that such Registered Security shall be immediately surrendered for redemption with written instruction for payment consistent with the provisions of this Indenture or (iv) to issue, register the transfer of or exchange any Security which, in accordance with its terms, has been surrendered for repayment at the option of the Holder, except the portion, if any, of such Security not to be so repaid.

43

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

(1) Each Registered Global Security authenticated under this Indenture shall be registered in the name of the Depositary designated for such Global Security or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single Security for all purposes of this Indenture.

(2) Any exchange or transfer of a Registered Global Security for other Securities may be made in whole or in part, and all Securities issued in exchange for or upon transfer of a Global Security or any portion thereof shall be registered in such names as the Depositary for such Global Security shall direct.

(3) Every Security authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Security or any portion thereof, whether pursuant to this Section, Section 304, 306, 905 or 1107 or otherwise, shall be authenticated and delivered in the form of, and shall be, a Global Security, unless such Security is registered in the name of a Person other than the Depositary for such Global Security or a nominee thereof.

Section 306. Mutilated, Destroyed, Lost and Stolen Securities.

If any mutilated Security or a Security with a mutilated Coupon appertaining to it is surrendered to the Trustee, subject to the provisions of this Section 306, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series containing identical terms and of like principal amount and bearing a number not contemporaneously outstanding, with Coupons appertaining thereto corresponding to the Coupons, if any, appertaining to the surrendered Security.

If there be delivered to the Company and to the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security or Coupon, and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security or Coupon has been acquired by a protected purchaser (as defined in the UCC), the Company shall execute and, upon the Company's request the Trustee shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Security or in exchange for the Security to which a destroyed, lost or stolen Coupon appertains with all appurtenant Coupons not destroyed, lost or stolen, a new Security of the same series containing identical terms and of like principal amount and bearing a number not contemporaneously outstanding, with Coupons corresponding to the Coupons, if any, appertaining to such destroyed, lost or stolen Security or to the Security to which such destroyed, lost or stolen Coupon appertains.

Notwithstanding the foregoing provisions of this Section 306, in case any mutilated, destroyed, lost or stolen Security or Coupon has become or is about to become due and payable,

44

the Company in its discretion may, instead of issuing a new Security, pay such Security or Coupon; provided, however, that payment of principal of, any premium or interest on or any Additional Amounts with respect to any Bearer Securities shall, except as otherwise provided in Section 1002, be payable only at an Office or Agency for such Securities located outside the United States and, unless otherwise provided in or pursuant to this Indenture (including this paragraph), any interest on Bearer Securities and any Additional Amounts with respect to such interest shall be payable only upon presentation and surrender of the Coupons appertaining thereto.

Upon the issuance of any new Security 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.

Every new Security, with any Coupons appertaining thereto issued pursuant to this Section in lieu of any destroyed, lost or stolen Security, or in exchange for a Security to which a destroyed, lost or stolen Coupon appertains shall constitute a separate obligation of the Company, whether or not the destroyed, lost or stolen Security and Coupons appertaining thereto or the destroyed, lost or stolen Coupon shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of such series and any Coupons, if any, duly issued hereunder.

The provisions of this Section, as amended or supplemented pursuant to this Indenture with respect to particular Securities or generally, shall be 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 or Coupons.

Section 307. Payment of Interest and Certain Additional Amounts; Rights to Interest and Certain Additional Amounts Preserved

Unless otherwise provided in or pursuant to this Indenture, any interest on and any Additional Amounts with respect to any Registered Security which shall be payable, and are punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name such Security (or one or more Predecessor Securities) is registered as of the close of business on the Regular Record Date for such interest. Unless otherwise provided in or pursuant to this Indenture, in case a Bearer Security is surrendered in exchange for a Registered Security after the close of business at an Office or Agency for such Security on any Regular Record Date therefor and before the opening of business at such Office or Agency on the next succeeding Interest Payment Date therefor, such Bearer Security shall be surrendered without the Coupon relating to such Interest Payment Date and interest shall not be payable on such Interest Payment Date in respect of the Registered Security issued in exchange for such Bearer Security, but shall be payable only to the Holder of such Coupon when due in accordance with the provisions of this Indenture.

45

Unless otherwise provided in or pursuant to this Indenture, any interest on and any Additional Amounts with respect to any Registered Security which shall be payable, but shall not be punctually paid or duly provided for, on any interest Payment Date for such Registered Security (herein called "Defaulted Interest") shall forthwith cease to be payable to the Holder thereof on the relevant Regular Record 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 Person in whose name such Registered Security (or a Predecessor Security thereof) shall be 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 such Registered Security and the date of the proposed payment, 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 payment, such money when so deposited to be held in trust for the benefit of the Person 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 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 the Holder of such Registered Security (or a Predecessor Security thereof) at his address as it appears in the Security Register not less than 10 days prior to such Special Record Date. The Trustee may, in its discretion, in the name and at the expense of the Company cause a similar notice to be published at least once in an Authorized Newspaper of general circulation in the Borough of Manhattan, The City of New York, but such publication shall not be a condition precedent to the establishment of 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 Person in whose name such Registered Security (or a Predecessor Security thereof) shall be registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2). In case a Bearer Security is surrendered at the Office or Agency for such Security in exchange for a Registered Security after the close of business at such Office or Agency on any Special Record Date and before the opening of business at such Office or Agency on the related proposed date for payment of Defaulted Interest, such Bearer Security shall be surrendered without the Coupon relating to such Defaulted Interest and Defaulted Interest shall not be payable on such proposed date of payment in respect of the Registered Security issued in exchange

46

for such Bearer Security, but shall be payable only to the Holder of such Coupon when due in accordance with the provisions of this Indenture.

(2) The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Security 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 payment shall be deemed practicable by the Trustee.

Unless otherwise provided in or pursuant to this Indenture or the Securities of any particular series, at the option of the Company, interest on Registered Securities that bear interest may be paid by mailing a check to the address of the Person entitled thereto as such address shall appear in the Security Register or by transfer to an account maintained by the payee with a bank located in the United States, provided that appropriate wire transfer instructions shall have been delivered by such payee to the Paying Agent at least five Business Days prior to the applicable date for payment of interest.

Subject to the foregoing provisions of this Section and Section 305, 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 interest accrued and unpaid, and to accrue, which were carried by such other Security.

Section 308. Persons Deemed Owners.

Prior to due presentment of a Registered 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 Registered Security is registered in the Security Register as the owner of such Registered Security for the purpose of receiving payment of principal of, any premium and (subject to Sections 305 and 307) interest on and any Additional Amounts with respect to such Registered Security and for all other purposes whatsoever, whether or not any payment with respect to such Registered Security shall be overdue, and neither the Company, the Trustee or any agent of the Company or the Trustee shall be affected by notice to the contrary.

The Company, the Trustee and any agent of the Company or the Trustee may treat the bearer of any Bearer Security or the bearer of any Coupon as the absolute owner of such Security or Coupon for the purpose of receiving payment thereof or on account thereof and for all other purposes whatsoever, whether or not any payment with respect to such Security or Coupon shall be overdue, and neither the Company, the Trustee or any agent of the Company or the Trustee shall be affected by notice to the contrary.

No holder of any beneficial interest in any Global Security held on its behalf by a U.S. Depositary or Depositary shall have any rights under this Indenture with respect to such Global Security, and such U.S. Depositary or Depositary may be treated by the Company, the Trustee, and any agent of the Company or the Trustee as the owner of such Global Security for all purposes

47

whatsoever. None of the Company, the Trustee, any Paying Agent or the Security Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

Section 309. Cancellation.

All Securities and Coupons surrendered for payment, redemption, registration of transfer, exchange or conversion or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee, and any such Securities and Coupons, as well as Securities and Coupons surrendered directly to the Trustee for any such purpose, shall be canceled promptly by the Trustee. 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 canceled promptly by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities canceled as provided in this Section, except as expressly permitted by or pursuant to this Indenture. All canceled Securities and Coupons held by the Trustee shall be disposed of by the Trustee in accordance with its customary procedures, unless by a Company Order the Company directs their return to it.

Section 310. Computation of Interest.

Except as otherwise provided in or pursuant to this Indenture or in the Securities of any series, interest on the Securities shall be computed on the basis of a 360-day year of twelve 30-day months.

Section 311. CUSIP, CINS or ISIN Numbers.

The Company in issuing the Securities may use "CUSIP", "CINS" or "ISIN" numbers (if then generally in use), and, if so, the Trustee or the Company shall use "CUSIP", "CINS" or "ISIN" numbers in notices of redemption or repurchase 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 or repurchase and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption or repurchase shall not be affected by any defect in or omission of such numbers. The Company shall promptly notify the Trustee of any change in "CUSIP", "CINS" or "ISIN" numbers.

ARTICLE FOUR

SATISFACTION AND DISCHARGE OF INDENTURE

Section 401. Satisfaction and Discharge.

48

Upon the direction of the Company by a Company Order, this Indenture shall cease to be of further effect with respect to any series of Securities specified in such Company Order and any Coupons appertaining thereto, and the Trustee, on receipt of a Company Order, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture as to such series, when

(1) either

(a) all Securities of such series theretofore authenticated and delivered and all Coupons appertaining thereto (other than (i) Coupons appertaining to Bearer Securities of such series surrendered in exchange for Registered Securities of such series and maturing after such exchange whose surrender is not required or has been waived as provided in Section 305, (ii) Securities and Coupons of such series which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 306,
(iii) Coupons appertaining to Securities of such series called for redemption and maturing after the relevant Redemption Date whose surrender has been waived as provided in Section 1106, and (iv) Securities and Coupons of such series for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 1003) have been delivered to the Trustee for cancellation; or

(b) all such Securities of such series and, in the case of (i) or (ii) below, any Coupons appertaining thereto not theretofore delivered to the Trustee for cancellation

(i) have become due and payable, or

(ii) will become due and payable at their Stated Maturity within one year, or

(iii) if redeemable at the option of the Company, are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, and the Company, in the case of (i), (ii) or
(iii) above, has deposited or caused to be deposited with the Trustee as trust funds in trust for such purpose, money in the Currency in which such Securities are payable in an amount sufficient to pay and discharge the entire indebtedness on such Securities and any Coupons appertaining thereto not theretofore delivered to the Trustee for cancellation, including the principal of, any premium and interest on, and, to the extent that the Securities of such series provide for the payment of Additional Amounts thereon and the amount of any such Additional Amounts is at the time of deposit reasonably determinable by the Company (in the exercise by the Company of its sole and absolute discretion), any Additional Amounts with respect to, such Securities and any Coupons appertaining thereto, to the date of such deposit (in the case of Securities which have become due and payable) or to the Maturity thereof, as the case may be;

49

(2) the Company has paid or caused to be paid all other sums payable hereunder by the Company with respect to the Outstanding Securities of such series and any Coupons appertaining thereto; and

(3) the Company has delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture as to such series have been complied with.

In the event there are Securities of two or more series hereunder, the Trustee shall be required to execute an instrument acknowledging satisfaction and discharge of this Indenture only if requested to do so with respect to Securities of such series as to which it is Trustee and if the other conditions thereto are met.

Notwithstanding the satisfaction and discharge of this Indenture with respect to any series of Securities, the obligations of the Company to the Trustee under Section 607 and, if money shall have been deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section, the obligations of the Company and the Trustee with respect to the Securities of such series under Sections 305, 306, 403, 1002 and 1003, with respect to the payment of Additional Amounts, if any, with respect to such Securities as contemplated by
Section 1004 (but only to the extent that the Additional Amounts payable with respect to such Securities exceed the amount deposited in respect of such Additional Amounts pursuant to Section 401(1)(b)), and with respect to any rights to convert or exchange such Securities into Capital Stock or other securities, shall survive.

Section 402. Defeasance and Covenant Defeasance.

(1) Unless, pursuant to Section 301, either or both of (i) defeasance of the Securities of or within a series under clause (2) of this Section 402 or (ii) covenant defeasance of the Securities of or within a series under clause (3) of this Section 402 shall not be applicable with respect to the Securities of such series, then such provisions, together with the other provisions of this Section 402 (with such modifications thereto as may be specified pursuant to Section 301 with respect to any Securities), shall be applicable to such Securities and any Coupons appertaining thereto, and the Company may at its option by Company Resolution, at any time, with respect to such Securities and any Coupons appertaining thereto, elect to have Section 402(2) or
Section 402(3) be applied to such Outstanding Securities and any Coupons appertaining thereto upon compliance with the conditions set forth below in this Section 402.

(2) Upon the Company's exercise of the above option applicable to this
Section 402(2) with respect to any Securities of or within a series, the Company shall be deemed to have been discharged from its obligations with respect to such Outstanding Securities and any Coupons appertaining thereto on the date the conditions set forth in clause (4) of this Section 402 are satisfied (hereinafter, "defeasance"). For this purpose, such defeasance means that the Company shall be deemed to have paid

50

and discharged the entire indebtedness represented by such Outstanding Securities and any Coupons appertaining thereto, which shall thereafter be deemed to be "Outstanding" only for the purposes of clause (5) of this Section 402 and the other Sections of this Indenture referred to in clauses (i) and (ii) below, and to have satisfied all of its other obligations under such Securities and any Coupons appertaining thereto and this Indenture insofar as such Securities and any Coupons appertaining thereto are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (i) the rights of Holders of such Outstanding Securities and any Coupons appertaining thereto to receive, solely from the trust fund described in clause (4) of this Section 402 and as more fully set forth in such Section, payments in respect of the principal of (and premium, if any) and interest, if any, on, and Additional Amounts, if any, with respect to, such Securities and any Coupons appertaining thereto when such payments are due, and any rights of such Holder to convert or exchange such Securities into Capital Stock or other securities, (ii) the obligations of the Company and the Trustee with respect to such Securities under Sections 305, 306, 1002 and 1003, with respect to the payment of Additional Amounts, if any, on such Securities as contemplated by Section 1004 (but only to the extent that the Additional Amounts payable with respect to such Securities exceed the amount deposited in respect of such Additional Amounts pursuant to
Section 401(4)(a) below), and with respect to any rights to convert or exchange such Securities into Capital Stock or other securities, (iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder (including under Section 607) and (iv) this Section 402. The Company may exercise its option under this Section 402(2) notwithstanding the prior exercise of its option under clause (3) of this Section 402 with respect to such Securities and any Coupons appertaining thereto.

(3) Upon the Company's exercise of the above option applicable to this
Section 402(3) with respect to any Securities of or within a series, the Company shall be released from any covenant applicable to such Securities specified pursuant to Section 301(19), with respect to such Outstanding Securities and any Coupons appertaining thereto on and after the date the conditions set forth in clause (4) of this Section 402 are satisfied (hereinafter, "covenant defeasance"), and such Securities and any Coupons appertaining thereto shall thereafter be deemed to be not "Outstanding" for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in connection with any such covenant, but shall continue to be deemed "Outstanding" for all other purposes hereunder. For this purpose, such covenant defeasance means that, with respect to such Outstanding Securities and any Coupons appertaining thereto, the Company may omit to comply with, and shall have no liability in respect of, any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a default or an Event of Default under

51

Section 501(4) or 501(7) or otherwise, as the case may be, but, except as specified above, the remainder of this Indenture and such Securities and Coupons appertaining thereto shall be unaffected thereby.

(4) The following shall be the conditions to application of clause (2) or
(3) of this Section 402 to any Outstanding Securities of or within a series and any Coupons appertaining thereto:

(a) The Company shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee satisfying the requirements of Section 608 who shall agree to comply with the provisions of this Section 402 applicable to it) as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of such Securities and any Coupons appertaining thereto, (1) an amount in Dollars or in such Foreign Currency in which such Securities and any Coupons appertaining thereto are then specified as payable at Stated Maturity, or (2) Government Obligations applicable to such Securities and Coupons appertaining thereto (determined on the basis of the Currency in which such Securities and Coupons appertaining thereto are then specified as payable at Stated Maturity) which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment of principal of (and premium, if any) and interest, if any, on such Securities and any Coupons appertaining thereto, money in an amount, or (3) a combination thereof, in any case, in an amount, sufficient, without consideration of any reinvestment of such principal and interest, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee (or other qualifying trustee) to pay and discharge, (y) the principal of (and premium, if any) and interest, if any, on, and, to the extent that such Securities provide for the payment of Additional Amounts thereon and the amount of any such Additional Amounts is at the time of deposit reasonably determinable by the Company (in the exercise by the Company of its sole and absolute discretion), any Additional Amounts with respect to, such Outstanding Securities and any Coupons appertaining thereto to and including the Stated Maturity of such principal or installment of principal or interest or the Redemption Date established pursuant to clause (d) below, if any, and (z) any mandatory sinking fund payments or analogous payments applicable to such Outstanding Securities and any Coupons appertaining thereto on the day on which such payments are due and payable in accordance with the terms of this Indenture and of such Securities and any Coupons appertaining thereto.

(b) Such defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a default under, this Indenture or any other material

52

agreement or instrument to which the Company is a party or by which it is bound.

(c) Solely in the case of an election under clause (2) of this
Section 402, no Event of Default or event which with notice or lapse of time or both would become an Event of Default with respect to such Securities and any Coupons appertaining thereto shall have occurred and be continuing on the date of such deposit and, with respect to defeasance only, at any time during the period ending on the 91st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period).

(d) If the Securities are to be redeemed prior to Stated Maturity (other than from mandatory sinking fund payments or analogous payments), notice of such redemption shall have been duly given pursuant to this Indenture or provision therefor satisfactory to the Trustee shall have been made.

(e) The Company shall have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance or covenant defeasance under clause (2) or (3) of this Section 402 (as the case may be) have been complied with.

(f) Notwithstanding any other provisions of this Section 402(4), such defeasance or covenant defeasance shall be effected in compliance with any additional or substitute terms, conditions or limitations which may be imposed on the Company in connection therewith pursuant to Section 301.

(5) Subject to the provisions of the last paragraph of Section 1003, all money and Government Obligations (or other property as may be provided pursuant to Section 301) (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 402(5) and Section 403, the "Trustee") pursuant to clause (4) of Section 402 in respect of any Outstanding Securities of any series and any Coupons appertaining thereto shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and any Coupons appertaining thereto and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders of such Securities and any Coupons appertaining thereto of all sums due and to become due thereon in respect of principal (and premium, if any) and interest and Additional Amounts, if any, but such money need not be segregated from other funds except to the extent required by law.

Unless otherwise specified in or pursuant to this Indenture or any Securities, if, after a deposit referred to in Section 402(4)(a) has been made,
(a) the Holder of a Security in respect of which such deposit was made is entitled to, and does, elect pursuant to Section 301 or the terms of such Security to receive payment in a Currency other than that in which the deposit pursuant to

53

Section 402(4)(a) has been made in respect of such Security, or (b) a Conversion Event occurs in respect of the Foreign Currency in which the deposit pursuant to

In no event shall the Trustee be liable for any acts or omissions of said trustee.

Section 405. Reinstatement.

If the Trustee (or other qualifying trustee) is unable to apply any money or Government Obligations in accordance with Section 401 or 402, as applicable, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company's obligations under this Indenture, the Securities and the Coupons, if any, appertaining thereto shall be revived and reinstated as though no deposit had occurred pursuant to Section 401 or 402 until such time as the Trustee (or other qualifying trustee) is permitted to apply all such money or Government Obligations in accordance with Section 401 or 402, as applicable; provided, however, that if the Company has made any payment of principal of or any premium or interest on any Securities or Coupons because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities or Coupons to receive such payment from the money or Government Obligations held by the Trustee (or other qualifying trustee).

At any time after Securities of any series have been accelerated and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of not less than a majority in principal amount of the Outstanding Securities of such series, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if

No such rescission shall affect any subsequent default or impair any right consequent thereon.

Section 503. Collection of Indebtedness and Suits for Enforcement by Trustee.

The Company covenants that if

due and unpaid, and may prosecute such proceeding to judgment or final decree, and may enforce the same against the Company or any other obligor upon such Securities and any Coupons appertaining thereto and collect the monies adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such Securities and any Coupons appertaining thereto, wherever situated.

If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series and any Coupons appertaining thereto by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or such Securities or in aid of the exercise of any power granted herein or therein, or to enforce any other proper remedy.

(2) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder of Securities or any Coupons 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 of Securities or any Coupons, to pay to the Trustee any amount due to 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 607.

59

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder of a Security or any Coupon any plan of reorganization, arrangement, adjustment or composition affecting the Securities or Coupons or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder of a Security or any Coupon in any such proceeding; provided, however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors' or other similar committee.

and in every such case the Company, the Trustee and each such Holder shall, subject to any determination in such proceeding, be restored severally and respectively to their former positions hereunder, and thereafter all rights and remedies of the Trustee and each such Holder shall continue as though no such proceeding had been instituted.

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities or Coupons in the last paragraph of Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to each and every Holder of a Security or a Coupon is intended to be exclusive of any other right or remedy, and every right and remedy, to the extent permitted by law, shall be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not, to the extent permitted by law, prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 511. Delay or Omission not Waiver.

No delay or omission of the Trustee or of any Holder of any Security or Coupon to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to any Holder of a Security or a Coupon may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by such Holder, as the case may be.

(c) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then, in any such case, (i) the Company, by or pursuant to a Company Resolution, may remove the Trustee with respect to all Securities or the Securities of such series, or (ii) subject to Section 315(e) of the Trust Indenture Act, any Holder of a Security who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities of such series and the appointment of a successor Trustee or Trustees.

Any Corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any Corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any Corporation succeeding to all or substantially all of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, without the

70

execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated but not delivered by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities.

Section 612. Appointment of Authenticating Agent.

The Trustee may appoint one or more Authenticating Agents acceptable to the Company with respect to one or more series of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of that or those series issued upon original issue, exchange, registration of transfer, partial redemption or partial repayment, or pursuant to Section 306, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee's certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent.

Each Authenticating Agent shall be acceptable to the Company and, except as provided in or pursuant to this Indenture, shall at all times be a corporation that would be permitted by the Trust Indenture Act to act as trustee under an indenture qualified under the Trust Indenture Act, is authorized under applicable law and by its charter to act as an Authenticating Agent and has a combined capital and surplus (computed in accordance with Section 310(a)(2) of the Trust Indenture Act) of at least $50,000,000 and subject to supervision or examination by Federal or State authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent 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 an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect specified in this Section.

Any Corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any Corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any Corporation succeeding to all or substantially all of the corporate agency or corporate trust business of an Authenticating Agent, shall be the successor of such Authenticating Agent hereunder, provided such Corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.

An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such

71

Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall (i) mail written notice of such appointment by first-class mail, postage prepaid, to all Holders of Registered Securities, if any, of the series with respect to which such Authenticating Agent shall serve, as their names and addresses appear in the Security Register, and (ii) if Securities of the series are issued as Bearer Securities, publish notice of such appointment at least once in an Authorized Newspaper in the place where such successor Authenticating Agent has its principal office if such office is located outside the United States. Any successor Authenticating Agent, upon acceptance of its appointment hereunder, shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

The Company agrees to pay each Authenticating Agent from time to time reasonable compensation for its services under this Section. If the Trustee makes such payments, it shall be entitled to be reimbursed for such payments, subject to the provisions of Section 607.

The provisions of Sections 308, 604 and 605 shall be applicable to each Authenticating Agent.

If an Authenticating Agent is appointed with respect to one or more series of Securities pursuant to this Section, the Securities of such series may have endorsed thereon, in addition to or in lieu of the Trustee's certificate of authentication, an alternate certificate of authentication in substantially the following form:

This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

THE CHASE MANHATTAN BANK,
As Trustee

By: _____________________________________ As Authenticating Agent

By: ______________________________________ Authorized Signatory

If all of the Securities of any series may not be originally issued at one time, and if the Trustee does not have an office capable of authenticating Securities upon original issuance located in a Place of Payment where the Company wishes to have Securities of such series authenticated upon original issuance, the Trustee, if so requested in writing (which writing need not be accompanied by or contained in an Officers' Certificate by the Company), shall appoint in accordance with this Section and such procedures as shall be acceptable to the Trustee an

72

Authenticating Agent having an office in a Place of Payment designated by the Company with respect to such series of Securities.

Section 613. Conflicting Interests.

If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. To the extent permitted by such Act, the Trustee shall not be deemed to have a conflicting interest by virtue of being a trustee under this Indenture with respect to Securities of more than one series; the Indenture (for 8.71% Junior Subordinated Deferrable Interest Debentures) dated as of January 13, 1997 between Markel Corporation and The Chase Manhattan Bank; the Indenture dated as of May 18, 1998, among Terra Nova Insurance (UK) Holdings PLC, Terra Nova (Bermuda) Holdings Ltd., and The Chase Manhattan Bank; the Indenture dated as of August 26, 1997, among Terra Nova Insurance (UK) Holdings PLC, Terra Nova (Bermuda) Holdings Ltd., and The Chase Manhattan Bank; and the Indenture dated as of October 26, 1993, between Markel Corporation and The Chase Manhattan Bank, including the 7.25% Notes due November 1, 2003 issued thereunder.

The Company may also from time to time designate one or more other Offices or Agencies where the Securities of one or more series may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an Office or Agency in each Place of Payment for Securities of any series for such purposes. The Company shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other Office or Agency. Unless otherwise provided in or pursuant to this Indenture, the Company hereby designates as the Place of Payment for each series of Securities the Borough of Manhattan, The City of New York, and initially appoints the Corporate Trust Office of the Trustee as the Company's Office or Agency in the Borough of Manhattan, The City of New York for such purpose. The Company may subsequently appoint a different Office or Agency in the Borough of Manhattan, The City of New York for the Securities of any series.

Section 1003. Money for Securities Payments to be Held in Trust.

If the Company shall at any time act as its own Paying Agent with respect to any series of Securities, it shall, on or before each due date of the principal of, any premium or interest on or Additional Amounts with respect to any of the Securities of such series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum in the Currency or Currencies in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series) sufficient to pay the principal or any premium, interest or Additional

81

Amounts so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided, and shall promptly notify the Trustee of its action or failure so to act.

Whenever the Company shall have one or more Paying Agents for any series of Securities, it shall, on or prior to each due date of the principal of, any premium or interest on or any Additional Amounts with respect to any Securities of such series, deposit with any Paying Agent a sum (in the Currency or Currencies described in the preceding paragraph) sufficient to pay the principal or any premium, interest or Additional Amounts so becoming due, such sum to be held in trust for the benefit of the Persons entitled thereto, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act.

The Company shall cause each Paying Agent for any series of Securities other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent shall:

(1) hold all sums held by it for the payment of the principal of, any premium or interest on or any Additional Amounts with respect to Securities of such series in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as provided in or pursuant to this Indenture;

(2) give the Trustee notice of any default by the Company (or any other obligor upon the Securities of such series) in the making of any payment of principal, any premium or interest on or any Additional Amounts with respect to the Securities of such series; and

(3) at any time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent.

The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same terms as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such sums.

Except as otherwise provided herein or pursuant hereto, any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, any premium or interest on or any Additional Amounts with respect to any Security of any series or any Coupon appertaining thereto and remaining unclaimed for two years after such principal or any such premium or interest or any such Additional Amounts shall have become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security or any Coupon appertaining thereto shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust

82

money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in an Authorized Newspaper in each Place of Payment for such series or to be mailed to Holders of Registered Securities of such series, or both, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication or mailing nor shall it be later than two years after such principal and any premium or interest or Additional Amounts shall have become due and payable, any unclaimed balance of such money then remaining will be repaid to the Company.

Section 1004. Additional Amounts.

If any Securities of a series provide for the payment of Additional Amounts, the Company agrees to pay to the Holder of any such Security or any Coupon appertaining thereto Additional Amounts as provided in or pursuant to this Indenture or such Securities. Whenever in this Indenture there is mentioned, in any context, the payment of the principal of or any premium or interest on, or in respect of, any Security of any series or any Coupon or the net proceeds received on the sale or exchange of any Security of any series, such mention shall be deemed to include mention of the payment of Additional Amounts provided by the terms of such series established hereby or pursuant hereto to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to such terms, and express mention of the payment of Additional Amounts (if applicable) in any provision hereof shall not be construed as excluding Additional Amounts in those provisions hereof where such express mention is not made.

Except as otherwise provided in or pursuant to this Indenture or the Securities of any series, if the Securities of a series provide for the payment of Additional Amounts, at least 10 days prior to the first Interest Payment Date with respect to such series of Securities (or if the Securities of such series shall not bear interest prior to Maturity, the first day on which a payment of principal is made), and at least 10 days prior to each date of payment of principal or interest if there has been any change with respect to the matters set forth in the below-mentioned Officers' Certificate, the Company shall furnish to the Trustee and the principal Paying Agent or Paying Agents, if other than the Trustee, an Officers' Certificate instructing the Trustee and such Paying Agent or Paying Agents whether such payment of principal of and premium, if any, or interest, if any, on the Securities of such series shall be made to Holders of Securities of such series or the Coupons appertaining thereto who are United States Aliens without withholding for or on account of any tax, assessment or other governmental charge described in the Securities of such series. If any such withholding shall be required, then such Officers' Certificate shall specify by country the amount, if any, required to be withheld on such payments to such Holders of Securities or Coupons, and the Company agrees to pay to the Trustee or such Paying Agent the Additional Amounts required by the terms of such Securities. The Company covenants to indemnify the Trustee and any Paying Agent for, and to hold them harmless against, any loss, liability or expense reasonably incurred without negligence or bad faith on their part arising out of or in connection with actions taken or omitted by any of them in reliance on any Officers' Certificate furnished pursuant to this Section.

83

Section 1005. Corporate Existence.

Subject to Article Eight, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and the rights (charter and statutory) and franchises of the Company; provided, however, that the Company shall not be required to preserve any such right or franchise if the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company, and that the loss thereof is not disadvantageous in any material respect to the Holders.

Section 1006. Company Statement as to Compliance.

The Company will deliver to the Trustee, within 120 days after the end of each fiscal year, an Officers' Certificate (which need not comply with Section 102), stating as to each signer, that

(1) a review of the activities of the Company during such year and of performance under this Indenture has been made under his or her supervision; and

(2) to the best of his or her knowledge, based on such review, (a) the Company has fulfilled all its obligations under and complied with all covenants and conditions contained in this Indenture throughout such year, or, if there has been a default in the fulfillment of any such covenant, condition or obligation, specifying each such default known to him or her and the nature and status thereof, and (b) no event has occurred and is continuing which is, or after notice or lapse of time or both would become, an Event of Default under Section 501, or, if such an event has occurred and is continuing, specifying each such event known to him or her and the nature and status thereof.

At least one of the Person's signing such Officers' Certificate shall be the Company's principal executive officer, principal financial officer or principal accounting officer.

Section 1007. Calculation of Original Issue Discount.

The Company shall file with the Trustee promptly after the end of each calendar year a written notice specifying the amount of original issue discount (including daily rates and accrual periods) accrued on Outstanding Securities, if any, as of the end of such year.

ARTICLE ELEVEN

REDEMPTION OF SECURITIES

Section 1101. Applicability of Article.

84

Redemption of Securities of any series at the option of the Company as permitted or required by the terms of such Securities shall be made in accordance with the terms of such Securities and (except as otherwise provided herein or pursuant hereto) this Article.

Section 1102. Election to Redeem; Notice to Trustee.

The election of the Company to redeem any Securities shall be evidenced by or pursuant to a Company Resolution. In case of any redemption at the election of the Company of less than all of the Securities of any series, the Company shall, at least 60 days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date and of the principal amount of Securities of such series to be redeemed and, in the event that the Company shall determine that the Securities of any series to be redeemed shall be selected from Securities of such series having the same issue date, interest rate or interest rate formula, Stated Maturity and other terms (the "Equivalent Terms"), the Company shall notify the Trustee of such Equivalent Terms. In the case of any redemption of Securities (a) prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture or (b) pursuant to an election of the Company which is subject to a condition specified in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers' Certificate evidencing compliance with such restriction or condition.

Section 1103. Selection by Trustee of Securities to be Redeemed.

If less than all of the Securities of any series are to be redeemed, the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee from the Outstanding Securities of such series not previously called for redemption, by such method as the Trustee shall deem fair and appropriate and which may provide for the selection for redemption of portions of the principal amount of Registered Securities of such series; provided, however, that no such partial redemption shall reduce the portion of the principal amount of a Registered Security of such series not redeemed to less than the minimum denomination for a Security of such series established herein or pursuant hereto.

The Trustee shall promptly notify the Company and the Security Registrar (if other than itself) in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed.

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which has been or is to be redeemed.

Unless otherwise specified in or pursuant to this Indenture or the Securities of any series, if any Security selected for partial redemption is converted or exchanged for Capital Stock or other securities in part before termination of the conversion or exchange right with respect to the portion of the Security so selected, the converted or exchanged portion of such Security shall be deemed

85

(so far as may be) to be the portion selected for redemption. Securities which have been converted or exchanged during a selection of Securities to be redeemed shall be treated by the Trustee as Outstanding for the purpose of such selection.

Section 1104. Notice of Redemption.

Notice of redemption shall be given in the manner provided in Section 106, not less than 20 nor more than 60 days prior to the Redemption Date, unless a shorter period is specified in the Securities to be redeemed, to the Holders of Securities to be redeemed. Failure to give notice by mailing in the manner herein provided to the Holder of any Registered Securities designated for redemption as a whole or in part, or any defect in the notice to any such Holder, shall not affect the validity of the proceedings for the redemption of any other Securities or portion thereof. Any notice that is mailed to the Holder of any Registered Securities in the manner herein provided shall be conclusively presumed to have been duly given, whether or not such Holder receives the notice.

All notices of redemption shall state:

(1) the Redemption Date,

(2) the Redemption Price, or if not then ascertainable, the manner of calculation thereof,

(3) if less than all Outstanding Securities of any series are to be redeemed, the identification (and, in the case of partial redemption, the principal amount) of the particular Security or Securities to be redeemed,

(4) in case any Security is to be redeemed in part only, the notice which relates to such Security shall state that on and after the Redemption Date, upon surrender of such Security, the Holder of such Security will receive, without charge, a new Security or Securities of authorized denominations for the principal amount thereof remaining unredeemed,

(5) that, on the Redemption Date, the Redemption Price shall become due and payable upon each such Security or portion thereof to be redeemed, and, if applicable, that interest thereon shall cease to accrue on and after said date,

(6) the place or places where such Securities, together (in the case of Bearer Securities) with all Coupons appertaining thereto, if any, maturing after the Redemption Date, are to be surrendered for payment of the Redemption Price and any accrued interest and Additional Amounts pertaining thereto,

(7) that the redemption is for a sinking fund, if such is the case,

(8) that, unless otherwise specified in such notice, Bearer Securities of any series, if any, surrendered for redemption must be accompanied by all Coupons maturing

86

subsequent to the date fixed for redemption or the amount of any such missing Coupon or Coupons will be deducted from the Redemption Price, unless security or indemnity satisfactory to the Company, the Trustee and any Paying Agent is furnished,

(9) if Bearer Securities of any series are to be redeemed and any Registered Securities of such series are not to be redeemed, and if such Bearer Securities may be exchanged for Registered Securities not subject to redemption on the Redemption Date pursuant to Section 305 or otherwise, the last date, as determined by the Company, on which such exchanges may be made,

(10) in the case of Securities of any series that are convertible or exchangeable into Capital Stock or other securities, the conversion or exchange price or rate, the date or dates on which the right to convert or exchange the principal of the Securities of such series to be redeemed will commence or terminate and the place or places where such Securities may be surrendered for conversion or exchange, and

(11) the CUSIP number or the Euroclear or the Cedel reference numbers of such Securities, if any (or any other numbers used by a U.S. Depositary or Depositary to identify such Securities).

A notice of redemption published as contemplated by Section 106 need not identify particular Registered Securities to be redeemed.

Unless otherwise specified with respect to any Securities in accordance with Section 301, with respect to any redemption of Securities at the election of the Company, unless, upon the giving of notice of such redemption, defeasance shall have been effected with respect to such Securities pursuant to Section 402, such notice may state that such redemption shall be conditional upon the receipt by the Trustee or the Paying Agent(s) for such Securities, on or prior to the date fixed for such redemption, of money sufficient to pay the principal of and any premium and interest on such Securities and that if such money shall not have been so received such notice shall be of no force or effect and the Company shall not be required to redeem such Securities. In the event that such notice of redemption contains such a condition and such money is not so received, the redemption shall not be made and within a reasonable time thereafter notice shall be given, in the manner in which the notice of redemption was given, that such money was not so received and such redemption was not required to be made, and the Trustee or Paying Agent(s) for the Securities otherwise to have been redeemed shall promptly return to the Holders thereof any of such Securities which had been surrendered for payment upon such redemption.

Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, on Company Request, by the Trustee in the name and at the expense of the Company.

The Company shall give the Trustee notice of the amount of any Redemption Price that is subject to calculation, promptly after the calculation thereof.

87

Section 1105. Deposit of Redemption Price.

On or prior to any Redemption Date, the Company shall deposit, with respect to the Securities of any series called for redemption pursuant to Section 1104, with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money in the applicable Currency sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date, unless otherwise specified pursuant to Section 301 for or in the Securities of such series) any accrued interest on and Additional Amounts with respect thereto, all such Securities or portions thereof which are to be redeemed on that date.

Section 1106. Securities Payable on Redemption Date.

Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, subject to the fourth paragraph of Section 1104, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest and the Coupons for such interest appertaining to any Bearer Securities so to be redeemed, except to the extent provided below, shall be void. Upon surrender of any such Security for redemption in accordance with said notice, together with all Coupons, if any, appertaining thereto maturing after the Redemption Date, such Security shall be paid by the Company at the Redemption Price, together with any accrued interest and Additional Amounts to the Redemption Date; provided, however, that, except as otherwise provided in or pursuant to this Indenture or the Bearer Securities of such series, installments of interest on Bearer Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable only upon presentation and surrender of Coupons for such interest (at an Office or Agency located outside the United States except as otherwise provided in Section 1002), and provided, further, that, except as otherwise specified in or pursuant to this Indenture or the Registered Securities of such series, installments of interest on Registered Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the Regular Record Dates therefor according to their terms and the provisions of Section 307.

If any Bearer Security surrendered for redemption shall not be accompanied by all appurtenant Coupons maturing after the Redemption Date, such Security may be paid after deducting from the Redemption Price an amount equal to the face amount of all such missing Coupons, or the surrender of such missing Coupon or Coupons may be waived by the Company and the Trustee if there be furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to the Trustee or any Paying Agent any such missing Coupon in respect of which a deduction shall have been made from the Redemption Price, such Holder shall be entitled to receive the amount so deducted; provided, however, that any interest or Additional Amounts represented by Coupons shall be payable only upon presentation and surrender of those Coupons

88

at an Office or Agency for such Security located outside of the United States except as otherwise provided in Section 1002.

If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal and any premium, until paid, shall bear interest from the Redemption Date at the rate prescribed therefor in the Security.

Section 1107. Securities Redeemed in Part.

Any Registered Security which is to be redeemed only in part shall be surrendered at any Office or Agency for such Security (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 his 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 Registered Security or Securities of the same series, containing identical terms and provisions, of any authorized denomination as requested by such Holder in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered. If a Security in global form is so surrendered, the Company shall execute, and the Trustee shall authenticate and deliver to the U.S. Depositary or other Depositary for such Security in global form as shall be specified in the Company Order with respect thereto to the Trustee, without service charge, a new Security in global form in a denomination equal to and in exchange for the unredeemed portion of the principal of the Security in global form so surrendered.

ARTICLE TWELVE

SINKING FUNDS

Section 1201. Applicability of Article.

The provisions of this Article shall be applicable to any sinking fund for the retirement of Securities of a series, except as otherwise permitted or required in or pursuant to this Indenture or any Security of such series issued pursuant to this Indenture.

The minimum amount of any sinking fund payment provided for by the terms of Securities of any series is herein referred to as a "mandatory sinking fund payment", and any payment in excess of such minimum amount provided for by the terms of Securities of such series is herein referred to as an "optional sinking fund payment". If provided for by the terms of Securities of any series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 1202. Each sinking fund payment shall be applied to the redemption of Securities of any series as provided for by the terms of Securities of such series and this Indenture.

Section 1202. Satisfaction of Sinking Fund Payments with Securities.

89

The Company may, in satisfaction of all or any part of any sinking fund payment with respect to the Securities of any series to be made pursuant to the terms of such Securities (1) deliver Outstanding Securities of such series (other than any of such Securities previously called for redemption or any of such Securities in respect of which cash shall have been released to the Company), together in the case of any Bearer Securities of such series with all unmatured Coupons appertaining thereto, and (2) apply as a credit Securities of such series which have been redeemed either at the election of the Company pursuant to the terms of such series of Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, provided that such Securities have not been previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such Securities for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly. If as a result of the delivery or credit of Securities of any series in lieu of cash payments pursuant to this Section 1202, the principal amount of Securities of such series to be redeemed in order to exhaust the aforesaid cash payment shall be less than $100,000, the Trustee need not call Securities of such series for redemption, except upon Company Request, and such cash payment shall be held by the Trustee or a Paying Agent and applied to the next succeeding sinking fund payment, provided, however, that the Trustee or such Paying Agent shall at the request of the Company from time to time pay over and deliver to the Company any cash payment so being held by the Trustee or such Paying Agent upon delivery by the Company to the Trustee of Securities of that series purchased by the Company having an unpaid principal amount equal to the cash payment requested to be released to the Company.

Section 1203. Redemption of Securities for Sinking Fund.

Not less than 75 days prior to each sinking fund payment date for any series of Securities, the Company shall deliver to the Trustee an Officers' Certificate specifying the amount of the next ensuing mandatory sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and crediting of Securities of that series pursuant to Section 1202, the basis for such credit, that such Securities have not been previously so credited and the optional amount, if any, to be added in cash to the next ensuing mandatory sinking fund payment, and will also deliver to the Trustee any Securities to be so credited and not theretofore delivered. If such Officers' Certificate shall specify an optional amount to be added in cash to the next ensuing mandatory sinking fund payment, the Company shall thereupon be obligated to pay the amount therein specified. Not less than 45 days before each such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 1103 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 1104. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 1106 and 1107.

REPAYMENT AT THE OPTION OF HOLDERS

Section 1301. Applicability of Article.

Repayment of Securities of any series before their Stated Maturity at the option of Holders thereof shall be made in accordance with the terms of such Securities and (except as otherwise specified by the terms of such series established pursuant to Section 301) in accordance with this Article.

Section 1302. Repayment of Securities.

Securities of any series subject to repayment in whole or in part at the option of the Holders thereof will, unless otherwise provided in the terms of such Securities, be repaid at a price equal to the principal amount thereof, together with interest, if any, thereon accrued to the Repayment Date specified in or pursuant to the terms of such Securities. The Company covenants that on or before the Repayment Date it will deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the principal (or, if so provided by the terms of the Securities of any series, a percentage of the principal) of, and (except if the Repayment Date shall be an Interest Payment Date) accrued interest on, all the Securities or portions thereof, as the case may be, to be repaid on such date.

Section 1303. Exercise of Option.

Securities of any series subject to repayment at the option of the Holders thereof will contain an "Option to Elect Repayment" form on such Securities. In order for any Security to be repaid at the option of the Holder, the Trustee must receive at the Place of Payment therefor specified in the terms of such Security (or at such other place or places of which the Company shall from time to time notify the Holders of such Securities) not earlier than 60 days nor later than 30 days prior to the Repayment Date (1) the Security so providing for such repayment together with the "Option to Elect Repayment" form duly completed by the Holder (or by the Holder's attorney duly authorized in writing) or (2) a facsimile transmission or a letter from a member of a national securities exchange, or the National Association of Securities Dealers, Inc. ("NASD"), or a commercial bank or trust company in the United States setting forth the name of the Holder of Security, the principal amount of the Security, the amount of the Security to be repaid, the certificate number or a description of the tenor and terms of the Security, a statement that the option to elect repayment is being exercised thereby and a guarantee that the Security to be repaid, together with the duly completed form entitled "Option to Elect Repayment", will be received by the Trustee not later than the fifth Business Day after the date of such facsimile transmission or letter; provided, however, that such facsimile transmission or letter shall only be effective if such Security and form duly completed are received by the Trustee by such fifth Business Day. If less than the entire principal amount of such Security is to be repaid in accordance with the terms of such Security, the principal amount of such Security to be repaid, in increments of the minimum denomination for Securities of such series, and the denomination or denominations of the Security or Securities to be issued to the Holder for the portion of the

91

principal amount of such Security surrendered that is not to be repaid, must be specified. The principal amount of any Security providing for repayment at the option of the Holder thereof may not be repaid in part if, following such repayment, the unpaid principal amount of such Security would be less than the minimum authorized denomination of Securities of the series of which such Security to be repaid is a part. Except as otherwise may be provided by the terms of any Security providing for repayment at the option of the Holder thereof, exercise of the repayment option by the Holder shall be irrevocable unless waived by the Company.

Section 1304. When Securities Presented for Repayment Become Due and Payable.

If the Securities of any series providing for repayment at the option of the Holders thereof shall have been surrendered as provided in this Article and as provided by or pursuant to the terms of such Securities, such Securities or the portions thereof, as the case may be, to be repaid shall become due and payable and shall be paid by the Company on the Repayment Date therein specified, and on and after such Repayment Date (unless the Company shall default in the payment of such Securities on such Repayment Date) such Securities so to be repaid shall cease to bear interest. Upon surrender of any such Security for repayment in accordance with such provisions, the principal amount of such Security so to be repaid shall be paid by the Company, together with accrued interest, if any, to the Repayment Date; provided that, installments of interest, if any, whose Stated Maturity is on or prior to the Repayment Date shall be payable (but without interest thereon, unless the Company shall default in the payment thereof) to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 307.

If the principal amount of any Security surrendered for repayment shall not be so repaid upon surrender thereof, such principal amount (together with interest, if any, thereon accrued to such Repayment Date) shall, until paid, bear interest from the Repayment Date at the rate of interest set forth in such Security.

Section 1305. Securities Repaid in Part.

Upon surrender of any Registered Security which is to be repaid in part only (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 Security Registrar duly executed by, the Holder thereof or his attorney duly authorized in writing), the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security, without service charge and at the expense of the Company, a new Registered Security or Securities of the same series, Stated Maturity and original issue date of any authorized denomination specified by the Holder, in an aggregate principal amount equal to and in exchange for the portion of the principal of such Security so surrendered which is not to be repaid.

Section 1306. Compliance with Exchange Act.

92

In connection with any repayment of Securities pursuant to this Article, the Company will comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act, if required, and will file Schedule 13E-4 or any other schedule, if required.

SECTION 205 Transfer and Exchange. (a) Notwithstanding any provision to the contrary herein, so long as a Global Note remains Outstanding and is held by or on behalf of the Depositary, transfers of a Global Note, in whole or in part, shall be made only in accordance with Section 208(a)(i) and this Section 205.

(b) Transfers of a Global Note shall be limited to transfers of such Global Note in whole, or in part, to nominees of the Depositary or to a successor of the Depositary or such successor's nominee.

SECTION 206 Registrar, Paying Agent, Conversion Agent and Bid Solicitation Agent. The Company shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange ("Registrar"), an office or agency where Notes may be presented for purchase or payment ("Paying Agent") and an office or agency where Notes may be presented for conversion ("Conversion Agent"). The Company shall also appoint a bid solicitation agent (the "Bid Solicitation Agent") to act pursuant to paragraph 3 in the Notes. The Registrar shall keep a register of the Notes 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. The term Conversion Agent includes any additional conversion agent.

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 the 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 therefore pursuant to Section 607 of the Original Indenture. The Company or any Subsidiary or an Affiliate of either of them may act as Paying Agent, Registrar, Conversion Agent or co-registrar.

or prior to each due date of payments in respect of any Notes, 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 Noteholders or the Trustee all money and Common Stock held by the Paying Agent for the making of payments in respect of the Notes 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 208 Restrictions on Transfers. (a) Notwithstanding any other provisions of this Supplemental Indenture or the Notes, (A) transfers of a Global Note, in whole or in part, shall be made only in accordance with Sections 205 and 208(a)(i), (B) transfer of a beneficial interest in a Global Note for a Certificated Note shall comply with Section 208(a)(ii) below, and (C) transfers of a Certificated Note shall comply with Section 208(a)(iii) and (iv) below.

(i) Transfer of Global Note. A Global Note may not be transferred, in whole or in part, to any Person other than the Depositary or a nominee 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 Note that is issued in exchange for a Global Note but is not itself a Global Note. No transfer of a Note to any Person shall be effective under the Indenture or the Notes unless and until such Note has been registered in the name of such Person. Nothing in this Section 208(a)(i) shall prohibit or render ineffective any transfer of a beneficial interest in a Global Note effected in accordance with the other provisions of this Section 208(a).

(ii) Restrictions on Transfer of a Beneficial Interest in a Global Note for a Certificated Note. A beneficial interest in a Global Note may not be exchanged for a Certificated Note 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 Global Note in accordance with Applicable Procedures for a Certificated Note in the form satisfactory to the Trustee, together with written instructions to the Trustee to make, or direct the Registrar to make, an adjustment on its books and records with respect to such Global Note to reflect a decrease in the aggregate Principal Amount at Maturity of the Notes represented by the Global Note, such instructions to contain information regarding the Depositary account to be credited with such decrease, then the Trustee shall cause, or direct the Registrar to cause, in accordance with the standing instructions and procedures existing between the Depositary and the Registrar, the aggregate Principal Amount at Maturity of Notes represented by the Global Note to be decreased by the aggregate Principal Amount at Maturity of the Certificated Note to be issued, shall issue such Certificated Note and shall

10

debit or cause to be debited to the account of the Person specified in such instructions a beneficial interest in the Global Note equal to the Principal Amount at Maturity of the Certificated Note so issued.

(iii) Transfer and Exchange of Certificated Notes. When Certificated Notes are presented to the Registrar with a request:

(x) to register the transfer of such Certificated Notes; or

(y) to exchange such Certificated Notes for an equal Principal Amount at Maturity of Certificated Notes of other authorized denominations,

the Registrar shall register the transfer or make the exchange as requested if its reasonable requirements for such transaction are met; provided, however, that the Certificated Notes surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer in form reasonably satisfactory to the Company and the Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing.

(iv) Restrictions on Transfer of a Certificated Note for a Beneficial Interest in a Global Note. A Certificated Note may not be exchanged for a beneficial interest in a Global Note except upon satisfaction of the requirements set forth below.

Upon receipt by the Trustee of a Certificated Note, duly endorsed or accompanied by appropriate instruments of transfer, in form satisfactory to the Trustee, together with written instructions directing the Trustee to make, or to direct the Registrar to make, an adjustment on its books and records with respect to such Global Note to reflect an increase in the aggregate Principal Amount at Maturity of the Notes represented by the Global Note, such instructions to contain information regarding the Depositary account to be credited with such increase, then the Trustee shall cancel such Certificated Note and cause, or direct the Registrar to cause, in accordance with the standing instructions and procedures existing between the Depositary and the Registrar, the aggregate Principal Amount at Maturity of Notes represented by the Global Note to be increased by the aggregate Principal Amount at Maturity of the Certificated Note to be exchanged, and shall credit or cause to be credited to the account of the Person specified in such instructions a beneficial interest in the Global Note equal to the Principal Amount at Maturity of the Certificated Note so cancelled. If no Global Notes are then outstanding, the Company shall issue and the Trustee shall authenticate, upon receipt of a Company Order, a new Global Note in the appropriate Principal Amount at Maturity.

(b) The provisions of clauses (i), (ii), (iii), (iv) and (v) below shall apply only to Global Notes:

(i) Notwithstanding any other provisions of the Indenture or the Notes, except as provided in Section 208(a)(ii), a Global Note shall not be exchanged in whole or in part for a Note registered in the name of any Person other than the Depositary or one or more nominees thereof, provided that a Global Note may be exchanged for Notes registered in the names of any person

11

designated by the Depositary in the event that (A) the Depositary has notified the Company that it is unwilling or unable to continue as depositary for such Global Note or the 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, (B) an Event of Default has occurred and is continuing with respect to the Notes or (C) if the Company executes and delivers a Company Order to the effect that the Global Note shall be exchangeable. Any Global Note exchanged pursuant to clause (A) above shall be so exchanged in whole and not in part, and any Global Note exchanged pursuant to clause (B) above may be exchanged in whole or from time to time in part as directed by the Depositary.

(ii) Notes issued in exchange for a Global Note 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 Note or portion thereof to be so exchanged and shall be registered in such names and be in such authorized denominations as the Depositary shall designate. Any Global Note to be exchanged in whole shall be surrendered by the Depositary to the Trustee, as Registrar. With regard to any Global Note to be exchanged in part, either such Global Note 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 Note, 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 adjustment made on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and deliver the Note issuable on such exchange to or upon the order of the Depositary or an authorized representative thereof.

(iii) Subject to the provisions of clause (v) 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 the Indenture or the Notes.

(iv) In the event of the occurrence of any of the events specified in clause (i) above, the Company will promptly make available to the Trustee a reasonable supply of Certificated Notes.

(v) 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 the Indenture with respect to any Global Note registered in the name of the Depositary or any nominee thereof, or under any such Global Note, 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 Note 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 Note.

ARTICLE 3

CONTINGENT CASH INTEREST

SECTION 301 Contingent Cash Interest. Commencing after June 5, 2006, the Company shall make Contingent Cash Interest payments to the Holders of Notes, as set forth in Section 302 below, during any six month period from June 6 to December 5 and from December 6 to June 5 (each a "Semiannual Period") if, but only if, the average LYONs Market Price of one Note for the five Trading Days in the relevant Five-Trading-Day Measurement Period equals 120% or more of the Relevant Value of such Note. During any Semiannual Period when Contingent Cash Interest is payable pursuant to this section, each Contingent Cash Interest payment due and payable on each $1,000 Principal Amount at Maturity of Note shall be calculated for any quarterly period of the applicable Semiannual Period, and in each instance shall equal the greater of (i) 0.0625% of the average LYONs Market Price for the relevant Five-Trading Day Measurement Period or (ii) the sum of all Regular Cash Dividends paid by the Company per share on the Common Stock during the applicable quarter of such Semiannual Period multiplied by the Conversion Rate. Contingent Cash Interest shall accrue as of the 15th day preceding the last day of the relevant Semiannual Period.

As used in this Article 3, "Five-Trading-Day Measurement Period" means the five Trading Days ending on the third Trading Day immediately preceding the first day of the applicable Semiannual Period; provided, however, that if the Company declares a Common Stock dividend for which the record date for such dividend (the "Common Stock Record Date") falls prior to the first day of the next Semiannual Period, but the payment date for such dividend for the Common Stock falls within such Semiannual Period, then, the "Five-Trading-Day Measurement Period" shall mean the five Trading Days ending on the third Trading Day immediately preceding such Common Stock Record Date. "Relevant Value" means the sum of the Issue Price, the accrued Original Issue Discount and accrued Contingent Additional Principal, if any, on such Note to the day of determination. "LYONs Market Price" means, as of any date of determination, the average of the secondary market bid quotations per $1,000 Principal Amount at Maturity of Notes obtained by the Bid Solicitation Agent for $10 million Principal Amount at Maturity of Notes at approximately 4:00 p.m., New York City time, on such determination date from three independent nationally recognized securities dealers (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 Notes as of such determination date, then the LYONs Market Price for such determination date shall equal the product of (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 406, 407 or 408 (subject to the conditions set forth in Sections 409 and 410).

The Original Issue Discount of the Notes will continue to accrue whether or not Contingent Cash Interest payments are made or any Contingent Additional Principal accrues.

13

SECTION 302 Payment of Contingent Cash Interest; Contingent Cash Interest Rights Preserved. If payable, Contingent Cash Interest shall be paid on the last day of such Semiannual Period (in each case, a "Contingent Cash Interest Payment Date") or, if the Company pays a Regular Cash Dividend on the Common Stock during a Semiannual Period, on the payment date for the related Common Stock dividend. Contingent Cash Interest payments on any Note that are payable, and are punctually paid or duly provided for, on any Contingent Cash Interest Payment Date shall be paid to the Person who is the Holder of that Note on the 15th day preceding the last day of such Semiannual Period (the "Contingent Cash Interest Record Date") or, if the Company pays regular cash dividends on the Common Stock during one quarter within such Semiannual Period, the Common Stock Record Date. Each payment of Contingent Cash Interest on any Note shall be paid (A) if such Note is held in the form of a Global Note, in same-day funds by transfer to an account maintained by the payee located inside the United States, or (B) if such Note is held in the form of a Certificated Note, by check, mailed to the address of such Holder as set forth in the Security Register. In the case of a Global Note, interest payable on any Contingent Cash Interest Payment Date will be paid to the Depositary for the purpose of permitting DTC to credit the interest received by it in respect of such Global Note to the accounts of the beneficial owners thereof. If the Company only pays a Regular Cash Dividend on the Common Stock during one quarter within such Semiannual Period, the remaining Contingent Cash Interest payments will accrue and be payable as of the 15th day preceding the last day of such Semiannual Period.

Upon determination that Holders of Notes will be entitled to receive Contingent Cash Interest during a Semiannual Period, prior to the start of such Semiannual Period, the Company will issue a press release and publish such information on its website as soon as practicable.

SECTION 303 Bid Solicitation Agent. The Bid Solicitation Agent shall solicit bids from securities dealers which the Company indicates that it believes are willing to bid for the Notes. The Company initially appoints the Trustee to act as the Bid Solicitation Agent. The Company may change the Bid Solicitation Agent at its discretion; provided, however, the Bid Solicitation Agent may not be an Affiliate of the Company.

ARTICLE 4

CONVERSION

SECTION 401 Conversion Privilege. A Holder of a Note may convert such Note into shares of Common Stock at any time during the periods and subject to the conditions stated in paragraph 9 in the Notes, subject to the provisions of this Article 4. The number of shares of Common Stock issuable upon conversion of a Note per $1,000 of Principal Amount at Maturity thereof (the "Conversion Rate") shall be determined in accordance with the provisions of paragraph 9 in the Notes.

A Holder may convert a portion of the Principal Amount at Maturity of a Note 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 Note also apply to conversion of a portion of a Note.

14

"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 407 or 408 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 402 Conversion Procedure. To convert a Note, a Holder must satisfy the requirements in paragraph 9 in the Notes. The date on which the Holder satisfies all those requirements is the conversion date (the "Conversion Date"). As soon as practicable after the Conversion Date, the Company shall deliver to the Holder, through the Conversion Agent, 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 403. The Company shall determine such full number of shares and the amounts of the required cash with respect to any fractional share, and shall set forth such information in an Officer's certificate delivered to the Conversion Agent. The Conversion Agent shall have no duties under this paragraph unless and until it has received such certificate.

The Person in whose name the certificate is registered shall be treated as a stockholder of record on and after the Conversion Date; provided, however, that no surrender of a Note 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 Note shall have been surrendered for conversion, as if the stock transfer books of the Company had not been closed. Upon conversion of a Note, such Person shall no longer be a Holder of such Note.

Holders may surrender a Note for conversion by means of book-entry delivery in accordance with paragraph 9 in the Notes and the regulations of the applicable book entry facility.

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 4. On conversion of a Note, that portion of accrued Tax Original Issue Discount, accrued Original Issue Discount and accrued Contingent Additional Principal, if any, attributable to the period from the Issue Date of the Note through the Conversion Date and (except as provided below) accrued Contingent Cash Interest, if any, with respect to the converted Note 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) in exchange for the Note 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) shall be treated as issued, to the extent thereof, first in exchange for accrued Tax Original Issue Discount, accrued Original Issue Discount and accrued Contingent Additional Principal, if any, through the Conversion Date and accrued Contingent Cash Interest, and the balance, if any,

15

of such fair market value of such Common Stock (and any such cash payment) shall be treated as issued in exchange for the Issue Price of the Note being converted pursuant to the provisions hereof.

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

A Note surrendered for conversion based on (a) the Common Stock price may be surrendered for conversion until the close of business on the Business Day immediately preceding June 5, 2031, (b) a credit downgrade may be surrendered for conversion until the close of business on any Business Day during the period of the continuance of the credit downgrade as more fully described in paragraph 9 in the Note, (c) the Note being called for redemption may be surrendered for conversion 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, and (d) upon the occurrence of certain corporate transactions more fully described in paragraph 9 in the Note may be surrendered for conversion at any time from and after the date which is 15 days prior to the anticipated effective date of such transaction until 15 days after the actual date of such transaction, and if such day is not a Business Day, the next occurring Business Day following such day.

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

SECTION 403 Fractional Shares. The Company will not issue a fractional share of Common Stock upon conversion of a Note. 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 per share Sale Price of the Common Stock, on the last Trading Day prior to the Conversion Date, by the fractional amount and rounding the product to the nearest whole cent.

SECTION 404 Taxes on Conversion. If a Holder converts a Note, 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 due because the shares are to be issued in a name other than the Holder's name. Nothing herein shall preclude the Company from any tax withholding or directing the withholding of any tax required by law or regulations.

SECTION 405 Company to Provide Stock. The Company shall, prior to issuance of any Notes under this Article 4, 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 Notes.

16

All shares of Common Stock delivered upon conversion of the Notes 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 created by the Company.

The Company will endeavor promptly to comply with all federal and state securities laws regulating the offer and delivery of shares of Common Stock upon conversion of Notes, 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 406 Adjustment for Change in Capital Stock. If, after the Issue Date of the Notes, the Company:

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

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

(c) subdivides its outstanding shares of Common Stock into a greater number of shares;

(d) combines its outstanding shares of Common Stock into a smaller number of shares;

(e) 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 Note thereafter converted may receive the number of shares or other units of Capital Stock of the Company which such Holder would have owned immediately following such action if such Holder had converted the Note 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.

SECTION 407 Adjustment for Rights Issue. Except as set forth in Section 419, if after the Issue Date, 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 (O + N)
     ----------------------
        (O + [(N x P)/M)]

17

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 407 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 406(b) applies or (ii) a distribution to which Section 408 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 407 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 407 applies, the fair market value (on the record date for the distribution to which this Section 407 applies) of:

(i) the Capital Stock of the Company distributed in respect of each share of Common Stock in such Section 406(b) distribution; and

(ii) the 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 408 distribution.

The Board of Directors shall determine fair market values for the purposes of this Section 407.

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 407 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 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 407 if the application of the formula stated above in this Section 407 would result in a value of R' that is equal to or less than the value of R.

SECTION 408 Adjustment for Other Distributions.(a) Subject to
408(b), if, after the Issue Date of the Notes, the Company distributes to all holders of its Common Stock any of its assets excluding distributions of Capital Stock or debt securities or any rights, warrants or options to purchase

18

securities of the Company (including securities or cash, but excluding (x) distributions of Capital Stock referred to in Section 406 and distributions of rights, warrants or options referred to in Section 407 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, 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 406(b) applies, for which (i) the record date shall occur on or before the record date for the distribution to which this Section 408 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 408 applies, the fair market value (on the record date for the distribution to which this Section 408 applies) of any Capital Stock of the Company distributed in respect of each share of Common Stock in such Section 406(b) distribution.

F = the fair market value (on the record date for the distribution to which this Section 408 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 408 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 408.

The adjustment shall become effective immediately after the record date for the determination of shareholders entitled to receive the distribution to which this Section 408 applies.

For purposes of this Section 408, the term "Extraordinary Cash Dividend" shall mean any cash dividend or distribution 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 Measurement Period.

19

(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 Cash Interest paid on a Note during the Ex-Dividend Measurement Period and divided by the conversion rate in effect on the payment date of such relevant Contingent Cash 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 408, 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 408.

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 406.

(b) If, after the Issue Date, 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, 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 Sale Prices of the Common Stock for the ten (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 New York Stock Exchange or such other national or regional 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 408(a) applies shall mean the number of securities distributed in respect of each share of Common Stock multiplied by the average of the Sale Prices of those securities distributed for the ten (10) Trading Days commencing on and including the fifth Trading Day after the effectiveness of the Ex-Dividend Date.

SECTION 409 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 and all adjustments that are made and carried forward shall be taken in the aggregate in order to determine if the 1% threshold is met.

All calculations under this Article 4 shall be made to the nearest cent or to the nearest 1/1,000th of a share, as the case may be.

SECTION 410 When No Adjustment Required. No adjustment need be made for a transaction referred to in Section 406, 407, 408 or 414 if Noteholders 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 Noteholders may include participation upon conversion provided that an adjustment shall be made at such time as the Noteholders 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 Notes become convertible pursuant to this Article 4 into cash, no adjustment need be made thereafter as to the cash. Interest will not accrue on the cash.

Notwithstanding any provision to the contrary in this Indenture, no adjustment shall be made in the Conversion Rate to the extent, but only to the extent, such adjustment results in the following quotient being less than the par value of the Common Stock: (i) the Issue Price plus accrued Original Issue Discount and Contingent Additional Principal, if any, as of the date such adjustment would otherwise be effective divided by (ii) the Conversion Rate as so adjusted.

No adjustment will be made pursuant to this Section 4 that would result, through the application of two or more provisions hereof, in the duplication of any adjustment.

SECTION 411 Notice of Adjustment. Whenever the Conversion Rate is adjusted, the Company shall promptly mail to Noteholders 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. Upon receipt by it of such notice, the Conversion Agent will promptly mail such notice to Noteholders at the Company's expense. 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 412 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 Noteholders and file with the Trustee and the Conversion Agent a notice of the increase. The Company

21

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 406, 407 or 408.

SECTION 413 Notice of Certain Transactions. If:

(a) the Company takes any action that would require an adjustment in the Conversion Rate pursuant to Section 406, 407 or 408 (unless no adjustment is to occur pursuant to Section 410); or

(b) the Company takes any action that would require a supplemental indenture pursuant to Section 414; or

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

then the Company shall mail to Noteholders 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.

SECTION 414 Reorganization of Company; Special Distributions. If the Company is a party to a transaction subject to Section 801 of the Original Indenture (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, property or other assets of the Company or any other Person) or a merger or binding share exchange which reclassifies or changes its outstanding Common Stock, the Person obligated to deliver securities, cash or other assets upon conversion of Notes shall enter into a supplemental indenture. If the issuer of securities deliverable upon conversion of Notes 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 Note 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 Note 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 4. The successor Company shall mail to Noteholders a notice briefly describing the supplemental indenture.

If this Section applies, neither Section 406 nor 407 applies.

22

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 would otherwise result in an adjustment in the Conversion Rate pursuant to the provisions of Section 408, then, from and after the record date for determining the holders of Common Stock entitled to receive the distribution, a Holder of a Note that converts such Note in accordance with the provisions of this Indenture shall upon such conversion be entitled to receive, in addition to the shares of Common Stock into which the Note 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 Note immediately prior to the record date for determining the holders of Common Stock entitled to receive the distribution.

SECTION 415 Company Determination Final. Any determination that the Company or the Board of Directors must make pursuant to Section 403, 406, 407, 408, 409, 410, 414 or 417 is conclusive.

SECTION 416 Trustee's Adjustment Disclaimer. The Trustee has no duty to determine when an adjustment under this Article 4 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 414 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 Notes. The Trustee shall not be responsible for the Company's failure to comply with this Article 4. Each Conversion Agent (other than the Company or an Affiliate of the Company) shall have the same protection under this Section 416 as the Trustee.

SECTION 417 Simultaneous Adjustments. In the event that this Article 4 requires adjustments to the Conversion Rate under more than one of Sections 406, 407 or 408, 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 406, second, the provisions of
Section 408 and, third, the provisions of Section 407.

SECTION 418 Successive Adjustments. After an adjustment to the Conversion Rate under this Article 4, any subsequent event requiring an adjustment under this Article 4 shall cause an adjustment to the Conversion Rate as so adjusted.

SECTION 419 Rights Issued in Respect of Common Stock Issued Upon Conversion. Each share of Common Stock issued upon conversion of Notes pursuant to this Article 4 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 shareholder rights agreement adopted by the Company, as the same may be amended from 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 Notes 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 4, there shall not be any adjustment to the conversion privilege or

23

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 such Rights Agreement, or the termination or invalidation of such Rights.

ARTICLE 5

PAYMENT OF CONTINGENT CASH INTEREST

SECTION 501 Contingent Cash Interest Payments. If applicable, Contingent Cash Interest on any Note that is payable, and is punctually paid or duly provided for, on any Contingent Cash Interest Payment Date shall be paid to the person in whose name that Note is registered on the Record Date or the Contingent Cash Interest Record Date, as applicable, at the office or agency of the Company maintained for such purpose. Each payment of Contingent Cash Interest on any Note shall be paid (A) if such Note is held in the form of a Global Note, in same-day funds by transfer to an account maintained by the payee located inside the United States, or (B) if such Note is held in the form of a Certificated Note, by check, mailed to the address of such Holder as set forth in the Security Register. In the case of a Global Note, Contingent Cash Interest payable on any applicable payment date will be paid to the Depositary, with respect to that portion of such Global Note 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 Global Note to the accounts of the beneficial owners thereof.

SECTION 502 Defaulted Interest. Any Contingent Cash Interest on any Note that is payable, but is not punctually paid or duly provided for, within 30 days following any Contingent Cash Interest 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 in the Notes), shall forthwith cease to be payable to the registered Holder thereof on the relevant Record Date or Contingent Cash Interest Record Date, as applicable, 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 (a) or (b) below:

(a) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes 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 Note 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 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 (the "Special Record Date") for the payment of such Defaulted Interest which shall be not more than 15 days and not less than ten (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 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 Notes at his address as it appears on the list of Noteholders maintained pursuant to Section 305 of the Original Indenture, as amended by Article 7 of this Supplemental Indenture, not less than 10 days prior to such Special Record Date. The Trustee may, in its discretion, in the name and at the expense of the Company, cause a similar notice to be published at least once in The Wall Street

24

Journal, but such publications shall not be a condition precedent to the establishment of 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 Notes are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (b).

(b) The Company may make payment of any Defaulted Interest on the Notes in any lawful manner not inconsistent with the requirements of any securities exchange on which such Notes 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 503 Interest Rights Preserved. Subject to Sections 205 and 208, the foregoing provisions of this Article 5 and Section 305 of the Original Indenture, as amended by Article 7 of this Supplemental Indenture, each Note delivered under this Supplemental Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to Contingent Additional Principal and Contingent Cash Interest accrued and unpaid, which were carried by such other Note.

ARTICLE 6

SECTION 603 Notice. In the event that any Contingent Additional Principal accrues on the Notes, the Company shall issue a press release to that effect. In addition, the Company shall publish such information on its website or through such other comparable public medium as may be widely in use at that time. The Company shall also notify the Trustee annually in writing, at such time that the Company files with the Trustee its annual reports or other information or documents pursuant to Section 704 of the Original Indenture, of any accrual of Contingent Additional Principal and the resulting increase in the Principal Amount at Maturity per Note. Following its receipt of such notice, the Trustee shall provide such information to DTC for dissemination to the participants of DTC.

ARTICLE 7

AMENDMENT OF CERTAIN PROVISIONS
OF THE ORIGINAL INDENTURE

SECTION 701 Amendments Relating to the Notes. The Original Indenture is hereby amended, solely with respect to the Notes (and not with respect to any other series of Securities that may be issued under the Original Indenture), as follows:

(a) Sections 202, 203, 204, 205 and 207 of the Original Indenture are hereby deleted in their entirety.

(b) Sections 304, 305 and 306 of the Original Indenture are hereby amended by replacing the words therein "principal amount" with "Principal Amount at Maturity," and the second paragraph of Section 307 of the Original Indenture is hereby deleted in its entirety.

26

(c) Article Four of the Original Indenture is hereby amended by replacing it in its entirety with the following:

ARTICLE FOUR

DISCHARGE OF INDENTURE

SECTION 401. Discharge of Liability on Notes. When (i) the Company delivers to the Trustee all outstanding Notes (other than Notes replaced pursuant to
Section 306 of the Original Indenture, as amended by Article 7 of the Supplemental Indenture) for cancellation or (ii) all outstanding Notes have become due and payable and the Company deposits with the Trustee cash or, if expressly permitted by the terms of the Notes, Common Stock sufficient to pay all amounts due and owing on all outstanding Notes (other than Notes replaced pursuant to Section 306 of the Original Indenture, as amended by Article 7 of the Supplemental Indenture), and if in either case the Company pays all other sums payable hereunder by the Company, then the Original Indenture and the Supplemental Indenture shall, subject to Section 607 of the Original Indenture, cease to be of further effect with respect to the Notes. The Trustee shall join in the execution of a document prepared by the Company acknowledging satisfaction and discharge of the Original Indenture and this Supplemental 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 402. 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 Notes that remains unclaimed for two years, subject to applicable unclaimed property law. After such 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 Noteholders with respect to such money or securities for that period commencing after the return thereof.

(d) Article Five of the Original Indenture is hereby amended by replacing it in its entirety with the following:

ARTICLE FIVE

REMEDIES

SECTION 501. Events of Default. An "Event of Default" means any one of the following events:

(a) a default in the payment of the Principal Amount at Maturity, Redemption Price, Purchase Price or Change in Control Purchase Price or Contingent Additional Principal, if any, on any Note when the same becomes due and payable pursuant to the terms hereof;

27

(b) a default in the payment of any Contingent Cash Interest when the same becomes due and payable pursuant to the terms of Article 3 of the Supplemental Indenture, which default continues for a period of 30 days;

(c) the failure of the Company to comply with any of its agreements in the Notes or this Supplemental Indenture (other than those referred to in clauses (a) or (b) above) upon the 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 Notes then outstanding and such failure (or the failure to obtain a waiver thereof) continues for 60 days after receipt by the Company of a Notice of Default;

(d) (i) The failure of the Company or any Subsidiary to make any payment by the end of any applicable grace period after maturity of indebtedness, which terms as used in this Supplemental Indenture means obligations (other than nonrecourse obligations) of the Company for borrowed money or evidenced by bonds, debentures, notes or similar instruments in an aggregate principal amount in excess of $20,000,000 and continuance of such failure, or (ii) the acceleration of indebtedness because of a default with respect to such indebtedness without such indebtedness having been discharged or such acceleration having been cured, waived, rescinded or annulled in case of (i) above, for a period of 10 days after written notice to the Company by the Trustee or to the Company and the Trustee by the Holders of not less than 25% in aggregate Principal Amount at Maturity of the Notes then outstanding; however, if any such failure or acceleration referred to in (i) or (ii) 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;

(e) the Company pursuant to or under or within the meaning of any Bankruptcy Law:

(i) commences a voluntary case or proceeding;

(ii) consents to the entry of an order for relief against it in an involuntary case or proceeding or the commencement of any case against it;

(iii) consents to the appointment of a Custodian of it or for any substantial part of its property;

(iv) makes a general assignment for the benefit of its creditors;

(v) files a petition in bankruptcy or answer or consent seeking reorganization or relief; or

(vi) consents to the filing of such petition or the appointment of or taking possession by a Custodian; or

(f) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

28

(i) is for relief against the Company in an involuntary case or proceeding, or adjudicates the Company insolvent or bankrupt;

(ii) appoints a Custodian of the Company or for any substantial part of its property; or

(iii) orders the winding up or liquidation of the Company and the order or decree remains unstayed and in effect for 60 days.

"Bankruptcy Law" means Title 11, United States Code, or any similar federal or state law for the relief of debtors.

"Custodian" means any receiver, trustee, assignee, liquidator, custodian or similar official under any Bankruptcy Law.

Notwithstanding anything herein to the contrary, a default 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 Notes at the time outstanding of the default and the Company does not cure such default (and such default is not waived) within the time specified in clause (b) or clause (c) 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 five (5) days after it becomes aware of the occurrence thereof, written notice of any Event of Default and any event which with the giving of notice or the lapse of time, or both, would become an Event of Default under clause (b) or clause (c) above, its status and what action the Company is taking or proposes to take with respect thereto.

SECTION 502. Acceleration. If an Event of Default (other than an Event of Default specified in Section 501(e) or (f) of the Original Indenture, as amended by Article 7 of the Supplemental Indenture) 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 Notes 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 such declaration, and any accrued and unpaid Contingent Cash Interest and any accrued Contingent Additional Principal through the date of such declaration, on all the Notes to be immediately due and payable. Upon such a declaration, such Issue Price plus accrued Original Issue Discount, such accrued and unpaid Contingent Cash Interest, if any, and accrued Contingent Additional Principal, if any, shall be due and payable immediately. If an Event of Default specified in Section 501(e) or (f) of the Original Indenture, as amended by Article 7 of the Supplemental Indenture, occurs and is continuing, the Issue Price plus accrued Original Issue Discount, and any accrued and unpaid Contingent Cash Interest and any accrued Contingent Additional Principal, on all the Notes to the date of the occurrence of such Event of Default shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Noteholders. The Holders of a majority in aggregate Principal Amount at Maturity of the Notes at

29

the time outstanding, by notice to the Trustee (and without notice to any other Noteholder) 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 and Contingent Additional Principal and any accrued and unpaid Contingent Cash Interest that have become due solely as a result of acceleration and if all amounts due to the Trustee under Section 607 of the Original Indenture have been paid. No such rescission shall affect any subsequent Default or impair any right consequent thereto.

SECTION 503. 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, accrued Original Issue Discount, Contingent Cash Interest, if any, and Contingent Additional Principal, if any, on the Notes or to enforce the performance of any provision of the Notes or the Original Indenture.

The Trustee may maintain a proceeding even if the Trustee does not possess any of the Notes or does not produce any of the Notes in the proceeding. A delay or omission by the Trustee or any Noteholder 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. No remedy is exclusive of any other remedy. All available remedies are cumulative.

SECTION 504. Waiver of Past Defaults. Subject to Section 502 of the Original Indenture, as amended by Article 7 of the Supplemental Indenture, the Holders of a majority in aggregate Principal Amount at Maturity of the Notes at the time outstanding, by notice to the Trustee (and without notice to any other Noteholder), may waive an existing Default and its consequences except (a) an Event of Default described in Section 501(a) of the Original Indenture, as amended by Article 7 of the Supplemental Indenture, (b) a Default in respect of a provision that under Section 902 of the Original Indenture, as amended by Article 7 of the Supplemental Indenture, cannot be amended without the consent of each Noteholder affected or (c) a Default which constitutes a failure to convert any Note in accordance with the terms of Article 4 of the Original Indenture, as amended by Article 7 of the Supplemental Indenture. 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 504 shall be in lieu of Section 316(a)1(B) of the Trust Indenture Act and such Section 316(a)1(B) is hereby expressly excluded from the Original Indenture, as permitted by the Trust Indenture Act.

SECTION 505. Control by Majority. The Holders of a majority in aggregate Principal Amount at Maturity of the Notes 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 Noteholders or would involve the Trustee in personal liability unless the Trustee is offered indemnity satisfactory to it. This Section 505 shall be in lieu of Section 316(a)1(A) of the Trust Indenture Act and such Section 316(a)1(A) is hereby expressly excluded from this Indenture, as permitted by the Trust Indenture Act.

SECTION 506. Limitation on Suits. A Noteholder may not pursue any remedy with respect to this Indenture or the Notes unless:

30

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

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

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

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

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

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

SECTION 507. Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Noteholder to receive payment of the Principal Amount at Maturity, Contingent Additional Principal, if any, Issue Price plus accrued Original Issue Discount, Redemption Price, Purchase Price, Change in Control Purchase Price or Contingent Cash Interest, if any, in respect of the Notes held by such Noteholder, on or after the respective due dates expressed in the Notes or any Redemption Date, and to convert the Notes in accordance with Article 4 of the Original Indenture, as amended by Article 7 of the Supplemental Indenture, 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 Noteholder.

SECTION 508. Collection Suit by Trustee. If an Event of Default described in Section 501(a) or (b) of the Original Indenture, as amended by Article 7 of the Supplemental Indenture, 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 Notes and the amounts provided for in Section 607 of the Original Indenture.

SECTION 509. 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 Notes or the property of the Company or of such other obligor or its creditors, the Trustee (irrespective of whether the Principal Amount at Maturity, Contingent Additional Principal, if any, Issue Price plus accrued Original Issue Discount, Redemption Price, Purchase Price, Change in Control Purchase Price or Contingent Cash Interest, if any, in respect of the Notes 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,

31

(a) to file and prove a claim for the whole amount of the Principal Amount at Maturity, Contingent Additional Principal, if any, Issue Price plus accrued Original Issue Discount, Redemption Price, Purchase Price, Change in Control Purchase Price or Contingent Cash 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 607 of the Original Indenture) and of the Noteholders allowed in such judicial proceeding, and

(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 Noteholder 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 Noteholders, 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 607 of the Original Indenture.

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

SECTION 510. Priorities. If the Trustee collects any money pursuant to this Article 5, it shall pay out the money in the following order:

FIRST: to the Trustee for amounts due under Section 607 of the Original Indenture;

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

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

The Trustee may fix a record date and payment date for any payment to Noteholders pursuant to this Section 510. At least 15 days before such record date, the Trustee shall mail to each Noteholder and the Company a notice that states the record date, the payment date and the amount to be paid.

SECTION 511. Undertaking for Costs. In any suit for the enforcement of any right or remedy under the Original 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 (other than the Trustee)

32

in the suit 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, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 511 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 507 of the Original Indenture, as amended by Article 7 of the Supplemental Indenture, or a suit by Holders of more than 10% in aggregate Principal Amount at Maturity of the Notes at the time outstanding. This Section 511 shall be in lieu of Section 315(e) of the Trust Indenture Act and such
Section 315(e) is hereby expressly excluded from the Original Indenture, as permitted by the Trust Indenture Act.

SECTION 512. 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 similar 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, Contingent Additional Principal, if any, Issue Price plus accrued Original Issue Discount, Redemption Price, Purchase Price, Change in Control Purchase Price or Contingent Cash Interest, if any, delivering Common Stock upon a conversion pursuant to Article 4 or paying the cash equivalent thereof, in respect of Notes, 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."

(e) (i) Section 901(3) of the Original Indenture is hereby amended by deleting the words therein "of principal of, any premium or interest on or any Additional Amounts."

(ii) Section 902 of the Original Indenture is hereby supplemented with the following:

"SECTION 902. Modification of Indenture with Consent of Holders of Notes. With the written consent of the Holders of at least a majority in aggregate Principal Amount at Maturity of the Notes at the time outstanding, the Company and the Trustee may amend the Original Indenture, the Supplemental Indenture or the Notes. However, without the consent of each Noteholder affected, an amendment to the Original Indenture, the Supplemental Indenture or the Notes may not:

(a) reduce the percentage in Principal Amount at Maturity of Notes whose Holders must consent to an amendment;

(b) make any change in the manner or rate of accrual of Original Issue Discount, Contingent Cash Interest or Contingent Additional Principal, reduce the rate of Contingent Cash Interest referred to in paragraph 1 in the Notes or extend the time for payment of Original Issue Discount, Contingent Cash Interest or Contingent Additional Principal on any Note;

33

(c) reduce the Principal Amount at Maturity, accrued Original Issue Discount, Contingent Additional Principal, if any, with respect to any Note, of or extend the Stated Maturity of any Note;

(d) reduce the Redemption Price, Purchase Price or Change in Control Purchase Price of any Note;

(e) make any Note payable in money or securities other than that stated in the Note;

(f) make any change in Section 506 of the Original Indenture, as amended by Article 7 of the Supplemental Indenture, or this Section 902, except to increase any percentage set forth therein;

(g) make any change that adversely affects the right to convert any Note;

(h) make any change that adversely affects the right to require the Company to purchase the Notes in accordance with the terms thereof and the terms of the Original Indenture, as amended by Article 7 of the Supplemental Indenture, or the Supplemental Indenture;

(i) reduce the percentage of Holders of the Notes whose consent is needed to modify or amend the Original Indenture, as amended by Article 7 of the Supplemental Indenture;

(j) impair the right to institute suit for the enforcement of any payment with respect to, or conversion of, the Notes; or

(k) reduce the amount of principal payable upon acceleration of maturity of the Notes, following an Event of Default.

It shall not be necessary for the consent of the Holders under this
Section 902 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 902 becomes effective, the Company shall mail to each Holder a notice briefly describing the amendment."

(f) Section 1001 of the Original Indenture is hereby amended by replacing it in its entirety with the following:

"SECTION 1001. Payment of Notes. The Company shall promptly make all payments in respect of the Notes on the dates and in the manner provided in the Notes, pursuant to the Original Indenture or the Supplemental Indenture. Any amounts to be given to the Trustee or Paying Agent, shall be deposited with the Trustee or Paying Agent by 10:00 a.m. (New York City time) by the Company. Principal Amount at Maturity, Issue Price plus accrued Original Issue Discount, Redemption Price, Purchase Price, Change in Control Purchase Price, Contingent Cash Interest and Contingent Additional Principal 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

34

Purchase Date or Change in Control Purchase Date, as the case may be) the Trustee or the Paying Agent holds, in accordance with the Original Indenture or the Supplemental 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 cash interest on overdue amounts at the rate per annum set forth in paragraph 1 in the Notes, 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 and Contingent Additional Principal, if any."

(g) Article Eleven of the Original Indenture is hereby amended by replacing it in its entirety with the following:

"ARTICLE ELEVEN

Redemption and Repurchases of Notes

SECTION 1101. Right to Redeem; Notices to Trustee. The Company, at its option, may redeem the Notes in accordance with the provisions of paragraphs 6 of the Notes. Prior to June 5, 2006, the Company cannot redeem the Notes at its option. Beginning on June 5, 2006, the Company may redeem the Notes for cash as a whole at any time, or in part from time to time. If the Company elects to redeem Notes pursuant to paragraph 6 in the Notes, it shall notify the Trustee in writing of the Redemption Date, the Principal Amount at Maturity of Notes to be redeemed and the Redemption Price.

The Company shall give the notice to the Trustee by a Company Order at least 60 days before the Redemption Date (unless a shorter notice shall be satisfactory to the Trustee). If fewer than all the Notes are to be redeemed, the record date relating to such redemption shall be selected by the Company and given to the Trustee, which record date shall not be less than ten days after the date of notice to the Trustee.

SECTION 1102. Selection of Notes to Be Redeemed. If less than all the Notes are to be redeemed, the Trustee shall select the Notes to be redeemed pro rata based on ownership thereof or by lot or by any other method the Trustee considers fair and appropriate (so long as such method is not prohibited by the rules of any stock exchange on which the Notes 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 Notes not previously called for redemption. The Trustee may select for redemption portions of the Principal Amount at Maturity of Notes that have denominations larger than $1,000.

Notes and any portions thereof that 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 Notes called for redemption also apply to portions of Notes called for redemption. The Trustee shall notify the Company promptly of the Notes or portions of Notes to be redeemed.

35

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

Nothing in this Section 1102 shall affect the right of any Holder to convert any Note pursuant to Article 4 of the Supplemental Indenture before the termination of the conversion right with respect thereto.

SECTION 1103. Notice of Redemption. At least 30 days but not more than 60 days before a Redemption Date, the Company shall give notice of redemption to each Holder of Notes to be redeemed in the manner provided in
Section 106 of the Original Indenture.

Failure to give notice by mailing in the manner herein provided to the Holder of any Notes designated for redemption as a whole or in part, or any defect in the notice to any such Holder, shall not affect the validity of the proceedings for the redemption of any other Notes or portion thereof. Any notice that is mailed to the Holder of any Notes in the manner herein provided shall be conclusively presumed to have been duly given, whether or not such Holder receives the notice.

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

(a) the Redemption Date;

(b) the Redemption Price;

(c) the Conversion Rate;

(d) the name and address of the Paying Agent and Conversion Agent and of the office or agency referred to in Section 1002 of the Original Indenture;

(e) that Notes called for redemption may be converted at any time before the close of business on the second Business Day immediately preceding the Redemption Date, even if not otherwise convertible at such time;

(f) that Holders who want to convert Notes must satisfy the requirements set forth in paragraph 9 in the Notes;

(g) that Notes called for redemption must be surrendered to the Paying Agent or at the office or agency referred to in Section 1002 of the Original Indenture to collect the Redemption Price;

(h) if fewer than all the outstanding Notes are to be redeemed, the certificate numbers and Principal Amounts at Maturity of the particular Notes to be redeemed;

36

(i) that, unless the Company defaults in making payment of such Redemption Price on Notes called for redemption, Original Issue Discount and Contingent Cash Interest (if any) will cease to accrue on and after the Redemption Date; and

(j) the CUSIP number of the Notes.

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 15 days (unless a shorter period shall be acceptable to the Trustee) prior to the date such notice of redemption must be mailed.

SECTION 1104. Effect of Notice of Redemption. Once notice of redemption is given, Notes called for redemption become due and payable on the Redemption Date and at the Redemption Price stated in the notice except for Notes which are converted in accordance with the terms of the Supplemental Indenture. Upon surrender to the Paying Agent, such Notes shall be paid at the Redemption Price stated in the notice.

SECTION 1105. Deposit of Redemption Price. Prior to 10:00 a.m. (New York City time), on the Redemption Date, the Company shall deposit with the Paying Agent (or if the Company or a Subsidiary of the Company or an Affiliate of any of them is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the Redemption Price of all Notes to be redeemed on that date other than Notes or portions of Notes 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 Notes pursuant to Article 4 of the Supplemental Indenture. If such money is then held by the Company or a Subsidiary or an Affiliate of the Company in trust and is not required for such purpose it shall be discharged from such trust. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon complying with this Section, the Paying Agent shall have no further liability for the money delivered to the Trustee.

SECTION 1106. Notes Redeemed in Part. Upon surrender of a Note that is redeemed in part, the Company shall execute and the Trustee shall authenticate and deliver to the Holder a new Note in an authorized denomination equal in Principal Amount to the unredeemed portion of the Note surrendered.

SECTION 1107. Purchase of Notes at the Option of the Holder. (a) General. If a Holder exercises its right to require the Company to repurchase the Notes, the Notes shall be purchased by the Company on June 5, 2002, June 5, 2004, June 5, 2006, June 5, 2011, June 5, 2016, June 5, 2021, and June 5, 2026 (each, a "Purchase Date"), at the purchase price of:

o $295.35 per $1,000 of Principal Amount at Maturity on June 5, 2002;

o $321.27 per $1,000 of Principal Amount at Maturity on June 5, 2004;

o $349.46 per $1,000 of Principal Amount at Maturity on June 5, 2006;

37

o $431.24 per $1,000 of Principal Amount at Maturity on June 5, 2011;

o $532.16 per $1,000 of Principal Amount at Maturity on June 5, 2016;

o $656.69 per $1,000 of Principal Amount at Maturity on June 5, 2021; and

o $810.36 per $1,000 of Principal Amount at Maturity on June 5, 2026

plus, if applicable, Contingent Additional Principal (each, a "Purchase Price," as applicable), at the option of the Holder thereof, upon:

(i) 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 at least 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 Note which the Holder will deliver to be purchased,

(B) the portion of the Principal Amount at Maturity of the Note 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 Note shall be purchased as of the Purchase Date pursuant to the terms and conditions specified in the Notes, and

(D) in the event the Company elects, pursuant to Section 1107(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 (or a portion thereof) in Common Stock is not satisfied prior to the close of business on such Purchase Date, as set forth in Section 1107(d), whether such Holder elects (x) to withdraw such Purchase Notice as to some or all of the Notes to which such Purchase Notice relates (stating the Principal Amount at Maturity and certificate numbers of the Notes as to which such withdrawal shall relate), or (y) to receive cash in respect of the entire Purchase Price for all Notes (or portions thereof) to which such Purchase Notice relates; and

(ii) book-entry transfer or delivery of such Note 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 1107 only if the Note so delivered to the Paying Agent shall conform in all respects to the description thereof in the related Purchase Notice.

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 1109 of the Original Indenture, as supplemented by Article 7 of the Supplemental Indenture, fails to indicate such Holder's choice with respect to the election set forth in clause (D) of Section 1107(a)(i), such Holder shall be deemed to

38

have elected to receive cash in respect of the Purchase Price for all Notes 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 1107, a portion of a Note 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 Note also apply to the purchase of such portion of such Note.

Any purchase by the Company contemplated pursuant to the provisions of this Section 1107 shall be consummated by the delivery of the consideration to be received by the Holder as promptly as practicable following the later of the Purchase Date and the time of delivery of the Note.

Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Purchase Notice contemplated by this Section 1107(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 1109 of the Original Indenture, as amended by Article 7 of the Supplemental Indenture.

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 Notes to be purchased pursuant to Section 1107(a) may be paid for, at the election of the Company, in cash or Common Stock, or in any combination of cash and Common Stock, subject to the conditions set forth in Sections 1107(c) and
(d). The Company shall designate, in the Company Notice delivered pursuant to
Section 1107(e), whether the Company will purchase the Notes for cash or Common Stock, or, if a combination thereof, the percentages of the Purchase Price of Notes 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 Notes 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 Notes are purchased pursuant to this Section 1107 shall receive the same percentage of cash or Common Stock in payment of the Purchase Price for such Notes, except (i) as provided in Section 1107(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 Notes of a Holder or Holders for Common Stock because any of the conditions specified in Section 1107(d) have not been satisfied, the Company may purchase the Notes 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 Noteholders except pursuant to this Section 1107(b) or pursuant to Section 1107(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:

39

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

(ii) the information required by Section 1107(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 1107(d) have been or will be complied with, and

(iv) whether the Company desires the Trustee to give the Company Notice required by Section 1107(e).

(c) Purchase with Cash. On each Purchase Date, at the option of the Company, the Purchase Price of Notes in respect of which a Purchase Notice pursuant to Section 1107(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 Notes.

(d) Payment by Issuance of Common Stock. On each Purchase Date, at the option of the Company, the Purchase Price of Notes in respect of which a Purchase Notice pursuant to Section 1107(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 Noteholders 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 Notes 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 Note purchased, the number of shares of Common Stock shall be based on the aggregate amount of Notes to be purchased.

Upon a payment by Common Stock pursuant to the terms hereof, that portion of accrued Original Issue Discount, accrued Contingent Additional Principal, if any, and accrued Tax Original Issue Discount attributable to the period from the Issue Date to the Purchase Date with respect to the purchased Note shall not be cancelled, extinguished or forfeited but rather shall be deemed paid in full to the Holder through the delivery of the Common Stock in exchange for the Note being purchased pursuant to the terms hereof, and the fair market value of such Common Stock (together with any cash payments in lieu of fractional shares of Common Stock) shall be treated as issued, to the extent thereof, first in exchange for the accrued Tax Original Issue Discount, accrued Original Issue Discount and accrued Contingent Additional Principal, if any, through the Purchase Date, and the balance, if any, of the fair market value of such shares of Common Stock shall be treated as issued in exchange for the Issue Price of the Note being purchased pursuant to the provisions hereof. If the Company elects to purchase the Notes by the issuance of shares of Common Stock, the Company Notice, as provided in Section 1107(e), shall be sent to the Holders (and to beneficial owners as required by applicable law) not later than the Company Notice Date.

40

The Company's right to exercise its election to purchase the Notes pursuant to Section 1107 through the issuance of shares of Common Stock shall be conditioned upon:

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

(2) 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, if the Common Stock is not then listed on a national or regional securities exchange, admitted for quotation on the National Association of Securities Dealers Automated Quotation System;

(3) the registration of the shares of Common Stock to be issued in respect of the payment of the Purchase Price under the Securities Act and the Exchange Act, in each case, if required;

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

(5) 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 Notes 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 Notes, will be validly issued, fully paid and nonassessable and shall be free of any preemptive rights and any lien or adverse claim (provided that such Opinion of Counsel may state that, insofar as it relates to the absence of such preemptive rights, liens and adverse claims, it is given upon the best knowledge of such counsel), and, in the case of such Officers' Certificate, stating that conditions (1),
(2), (3) and (4) 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 (2), (3) and (4) 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 Notes 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 or by other appropriate means. 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 Notes pursuant to this Section 1107 through the issuance of shares of Common Stock, the Company shall pay the entire Purchase Price of the Notes of such Holder or Holders in cash.

41

(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 106 of the Original Indenture (the "Company Notice"). The Company Notice shall be sent to the Holders (and to beneficial owners as required by applicable law) not less than 20 Business Days prior to the applicable Purchase Date (the "Company Notice Date"). 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 Notes 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 Noteholder that wishes to exercise its option to have the Company repurchase the Notes 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 Cash Interest, if any, that will be accrued and payable with respect to the Notes as of the Purchase Date;

(ii) whether the Company will pay the Purchase Price in cash or in Common Stock or any combination thereof, specifying the percentage of each;

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

(iv) that Notes as to which a Purchase Notice has been given may be converted pursuant to Article Eleven of the Original Indenture, as amended by Article 7 of the Supplemental Indenture, only if any applicable Purchase Notice has been withdrawn in accordance with the terms of the Original Indenture, as amended by Article 7 of the Supplemental Indenture;

42

(v) that Notes must be surrendered to the Paying Agent to collect payment of the Purchase Price;

(vi) that the Purchase Price for any Note as to which a Purchase Notice has been given and not withdrawn will be paid as promptly as practicable following the later of the Purchase Date and the time of surrender of such Note as described in (v);

(vii) the procedures the Holder must follow to exercise rights under this Section 1107 and a brief description of those rights;

(viii) briefly, the conversion rights of the Notes and that Holders who want to convert Notes must satisfy the requirements set forth in paragraph 9 in the Notes;

(ix) the procedures for withdrawing a Purchase Notice (including, without limitation, for a conditional withdrawal pursuant to the terms of
Section 1107(a)(i)(D) or Section 1109 of the Original Indenture, as amended by Article 7 of the Supplemental Indenture);

(x) that, unless the Company defaults in making payment of such Purchase Price on Notes surrendered for purchase, Original Issue Discount, Contingent Additional Principal, if any, and Contingent Cash Interest, if any, will cease to accrue on and after the Purchase Date; and

(xi) the CUSIP number of the Notes.

At the Company's request and upon being provided with a copy of such Company Notice, the Trustee shall give such Company Notice in the Company's name and at the Company's expense, provided that the Company makes such request at least 15 days (unless a shorter period shall be acceptable to the Trustee) prior to the date such Company Notice must be mailed; and provided, further, 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 issued for each $1,000 Principal Amount at Maturity of Notes, the Company will issue a press release and publish such determination on the Company's web site or, at the Company's option, otherwise publicly disclose such information.

(f) Covenants of the Company. All shares of Common Stock delivered upon purchase of the Notes 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 created by the Company.

The Company shall use its reasonable efforts to list or cause to have quoted any shares of Common Stock to be issued to purchase Notes on the principal United States securities exchange or over-the-counter or other

43

domestic market on which any other shares of the Common Stock are then listed or quoted. The Company will promptly inform the Trustee in writing of any such listing.

(g) Procedure upon Purchase. On or before the Purchase Date, the Company shall deposit cash (in respect of a cash purchase under Section 1107(c) or for fractional interests, as applicable) or shares of Common Stock, or a combination thereof, as applicable, at the time and in the manner as provided in
Section 1110 of the Original Indenture, as amended by Article 7 of the Supplemental Indenture, sufficient to pay the aggregate Purchase Price of all Notes to be purchased pursuant to this Section 1107. 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 Business Day following the Purchase Date. Subject to
Section 1107(d), 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 Note 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 the Company from withholding or directing the withholding of any tax required by law or regulations.

SECTION 1108. Purchase of Notes at Option of the Holder upon Change in Control. (a) If on or prior to June 5, 2006 there shall have occurred a Change in Control, Notes shall be purchased by the Company, at the option of the Holder thereof, at a purchase price specified in paragraph 7 in the Notes (the "Change in Control Purchase Price"), as of the date that is 35 Business Days after the occurrence of the Change in Control (the "Change in Control Purchase Date"), subject to satisfaction by or on behalf of the Holder of the requirements set forth in Section 1108(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 any Affiliate or Associate of the Company, other than the Company, 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 the Common Stock and other Capital Stock with equivalent voting rights, or other capital stock into which the Common Stock is reclassified or changed, provided, however, that a person shall not be deemed a 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

44

Affiliates or Associates 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) there shall be consummated any share exchange, consolidation or merger of the Company pursuant to which the Common Stock would be converted into cash, securities or other property in which the holders of the Common Stock and other Capital Stock with equivalent voting rights immediately prior to such 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 and surviving corporation immediately after such share exchange, consolidation or merger of the Company.

Notwithstanding the foregoing provisions of this Section 1108, a Change in Control shall not be deemed to have occurred by virtue of the Company, any Subsidiary, any employee stock ownership plan or any other employee benefit plan of the Company or any Subsidiary, or any person holding Common Stock for or pursuant to the terms of any such employee benefit plan, filing or becoming obligated to file a report under or in response to Schedule 13D or Schedule TO (or any successor schedule, form or report) under the Exchange Act disclosing beneficial ownership by it of shares of Common Stock, whether in excess of 50% or otherwise.

"Associate" shall have the meaning ascribed to such term in Rule 12b-2 of the General Rules and Regulations under the Exchange Act, as in effect on the date hereof.

(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 Noteholder 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 1108 must be given;

(3) the Change in Control Purchase Date;

(4) the Change in Control Purchase Price;

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

(6) the Conversion Rate and any adjustments thereto;

(7) that Notes as to which a Change in Control Purchase Notice is given by the Holder may be converted, if otherwise convertible, only if the

45

Change in Control Purchase Notice has been withdrawn in accordance with the terms of the Original Indenture, as amended by Article 7 of the Supplemental Indenture;

(8) that Notes must be surrendered to the Paying Agent to collect payment of the Change in Control Purchase Price;

(9) that the Change in Control Purchase Price for any Note as to which a Change in Control Purchase Notice has been duly given and not withdrawn will be paid as promptly as practicable following the later of the Change in Control Purchase Date and the time of surrender of such Note as described in clause (8), above;

(10) the procedures the Holder must follow to exercise rights under this Section 1108 and a brief description of those rights;

(11) briefly, the conversion rights of the Notes (including whether the Notes are then currently convertible);

(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 on Notes surrendered for purchase, Original Issue Discount and Contingent Cash Interest, if any, will cease to accrue on and after the Change in Control Purchase Date; and

(14) the CUSIP number of the Notes.

(c) A Holder may exercise its rights specified in Section 1108(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 Note which the Holder will deliver to be purchased;

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

(3) that such Note shall be purchased pursuant to the terms and conditions specified in the Notes.

The delivery of such Note 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 1108 only if the Note so delivered to the Paying Agent or such office or agency shall conform in all respects to the description thereof set forth in the related Change in Control Purchase Notice and such Change in Control Purchase Notice shall not be validly withdrawn by the Holder.

46

The Company shall purchase from the Holder thereof, pursuant to this
Section 1108, a portion of a Note if the Principal Amount at Maturity of such portion is $1,000 or an integral multiple of $1,000. Provisions of the Original Indenture, as amended by Article 7 of the Supplemental Indenture, that apply to the purchase of all of a Note also apply to the purchase of such portion of such Note.

Any purchase by the Company contemplated pursuant to the provisions of this Section 1108 shall be consummated by the delivery of the consideration to be received by the Holder as promptly as practicable following the later of the Change in Control Purchase Date and the time of delivery of the Note to the Paying Agent in accordance with this Section 1108.

Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Change in Control Purchase Notice contemplated by this
Section 1108(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 1109 of the Original Indenture, as amended by Article 7 of the Supplemental Indenture.

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

SECTION 1109. 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 1108(a) or Section 1108(c) of the Original Indenture, as amended by Article 7 of the Supplemental Indenture, as applicable, the Holder of the Note 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, with respect to such Note to the Purchase Date or Change in Control Purchase Date, as the case may be. Such Purchase Price or Change in Control Purchase Price shall be paid to such Holder, subject to receipts of funds and/or Common Stock by the Paying Agent, as promptly as practicable following the later of (x) the Purchase Date or the Change in Control Purchase Date, as the case may be, with respect to such Note (provided the conditions in Section 1107(a) or Section 1108(c) of the Original Indenture, as amended by Article 7 of the Supplemental Indenture, as applicable, have been satisfied) and (y) the time of delivery of such Note to the Paying Agent by the Holder thereof in the manner required by
Section 1107(a) or Section 1108(c) of the Original Indenture, as amended by Article 7 of the Supplemental Indenture, as applicable. Notes 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 Eleven of the Original Indenture, as amended by Article 7 of the Supplemental Indenture, 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.

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

46

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 Principal Amount at Maturity of the Notes with respect to which such notice of withdrawal is being submitted,

(2) the certificate number of the Notes in respect of which such notice of withdrawal is being submitted, and

(3) the Principal Amount at Maturity, if any, of any such Notes which remain 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 1107(a)(i)(D) of the Original Indenture, as amended by Article 7 of the Supplemental Indenture, or (ii) a conditional withdrawal containing the information set forth in Section 1107(a)(i)(D) of the Original Indenture, as amended by Article 7 of the Supplemental Indenture, 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 Notes pursuant to Section 1107 of the Original Indenture, as amended by Article 7 of the Supplemental Indenture (other than through the issuance of Common Stock in payment of the Purchase Price, including cash in lieu of fractional shares) or 1108 the Original Indenture, as amended by Article 7 of the Supplemental Indenture, if there has occurred (prior to, on or after, as the case may be, the giving, by the Holders of such Notes, 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, with respect to such Notes). The Paying Agent will promptly return to the respective Holders thereof any Notes (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 the Original Indenture, as amended by Article 7 of the Supplemental 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, with respect to such Notes) 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 1110. Deposit of Purchase Price or Change in Control Purchase Price. Prior to 10:00 a.m. New York City time 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 1003 of the Original Indenture) an amount of money (in immediately available funds if deposited on such Business Day) or Common Stock, if permitted hereunder, sufficient to pay the aggregate Purchase Price or Change in Control Purchase

49

Price, as the case may be, of all the Notes or portions thereof which are to be purchased as of the Purchase Date or Change in Control Purchase Date, as the case may be. After the Purchase Date or the Change in Control Purchase Date, Original Issue Discount, Tax Original Issue Discount, and Contingent Cash Interest, if any, shall cease to accrue on such Note, whether or not such Note is delivered to the Paying Agent.

SECTION 1111. Notes Purchased in Part. Any Note 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 Note, without service charge, a new Note or Notes, of any authorized denomination as requested by such Holder in aggregate Principal Amount equal to, and in exchange for, the portion of the Principal Amount at Maturity of the Note so surrendered which is not purchased.

SECTION 1112. Covenant to Comply with Securities Laws upon Purchase of Notes. (a) In connection with any offer to purchase or purchase of Notes under Section 1107 or 1108 of the Original Indenture, as amended by Article 7 of the Supplemental Indenture (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 (i) comply with Rule 13e-4 and Rule 14e-1 under the Exchange Act and any other then applicable tender offer rules,
(ii) file the related Schedule TO (or any successor schedule, form or report) 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 1107 and 1108 of the Original Indenture, as amended by Article 7 of the Supplemental Indenture, to be exercised in the time and in the manner specified in Sections 1107 and 1108 of the Original Indenture, as amended by Article 7 of the Supplemental Indenture.

(b) The Company may not waive its obligation to purchase the Notes at the option of Holders in the event of a Change in Control.

SECTION 1113. 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 13 in the Notes, together with interest or dividends, if any, thereon (subject to the provisions of Sections 606 and 1003 of the Original Indenture), held by them for the payment of the Purchase Price or Change in Control Purchase Price, as the case may be; provided, however, that to the extent that the aggregate amount of cash or shares of Common Stock deposited by the Company pursuant to Section 1110 of the Original Indenture, as amended by Article 7 of the Supplemental Indenture, exceeds the aggregate Purchase Price or Change in Control Purchase Price, as the case may be, of the Notes 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, then as promptly as practicable 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 Sections 606 and 1003 of the Original Indenture of the Original Indenture).

49

Notwithstanding anything in the Original Indenture to the contrary, all moneys delivered to the Trustee (in any capacity) for payment to Holders shall remain uninvested unless otherwise agreed to in writing between the Company and the Trustee."

(h) Article Twelve of the Original Indenture is hereby deleted in its entirety.

(i) Article Thirteen of the Original Indenture is hereby deleted in its entirety.

SECTION 702 Interpretation of Original Indenture. Except as otherwise specifically provided in this Supplemental Indenture, whenever in the Original Indenture there is mentioned, in any context, the principal of or principal amount of any Security of any series or a percentage in principal amount of the Outstanding Securities of any series, such mention shall be deemed to be, solely with respect to the Notes, the Principal Amount at Maturity of the Notes or a percentage of the aggregate Principal Amount at Maturity of the Notes at the time Outstanding.

ARTICLE 8

TAX MATTERS

SECTION 801 Tax Treatment. The parties hereto hereby agree, and each Holder and any beneficial holder of a Note by its purchase of a Note hereby agrees:

(a) to treat the Notes as indebtedness of the Company for all tax purposes;

(b) to treat the Notes as debt instruments that are subject to U.S. Treasury Regulation section 1.1275-4(b); and

(c) to treat any payment to and receipt by a Holder of Common Stock upon conversion of a Note, or upon a redemption of a Note where the Company elects to pay in Common Stock, as a contingent payment under U.S. Treasury Regulation section 1.1275-4(b).

SECTION 802 Comparable Yield and Projected Payment Schedule. Solely for purposes of applying U.S. Treasury Regulation section 1.1275-4 to the Notes:

(a) for United States Federal income tax purposes, the Company shall accrue interest with respect to outstanding Notes as original issue discount according to the "noncontingent bond method," as set forth in U.S. Treasury Regulation Section 1.1275-4(b) using a comparable yield of 8.30%, compounded semiannually, and the projected payment schedule attached as Annex 1 to this Supplemental Indenture;

(b) the Company shall file with the Trustee promptly at the end of each calendar year (i) a written notice specifying the amount of original issue discount for United States federal income tax purposes (including daily rates and accrual periods) accrued on outstanding Notes as of the end of such year and (ii) such other specific information relating to such original issue discount as may then be relevant under the Internal Revenue Code of 1986, as

50

amended from time to time, including the amount of any adjustment made under the noncontingent bond method to account for the amount of any difference between the amount of an actual payment and the amount of a projected payment; and

(c) the Company acknowledges and agrees, and each Holder and any beneficial holder of a Note, by its purchase of a Note shall be deemed to acknowledge and agree, that (i) the comparable yield and the projected payment schedule are determined on the basis of an assumption of linear growth of stock price and a constant dividend yield, (ii) the comparable yield and the projected payment schedule are not determined for any purpose other than for the purpose of applying U.S. Treasury Regulation section 1.1275-4(b)(4) to the Note and (iii) the comparable yield and the projected payment schedule do not constitute a projection or representation regarding the actual amounts payable on the Notes.

[REVERSE SIDE OF GLOBAL NOTE]

Liquid Yield Option(TM) Note due 2031
(Zero Coupon-Senior)

1. Interest.

This Note shall not bear interest, except as specified in this paragraph or in paragraph 5.A 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 502 of the Original Indenture, as amended by Article 7 of the Supplemental 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 Note) or if Contingent Cash Interest, if any, due hereon or any portion of such Contingent Cash Interest is not paid when due in accordance with paragraph 5.A hereof, or if Contingent Additional Principal, if any, due hereon or any portion of such Contingent Additional Principal is not paid when due in accordance with paragraph 5.B hereof, then in each such case the overdue amount shall, to the extent permitted by law, bear interest at the rate of 4.25% per annum, compounded semi-annually, 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 Note), in the period during which a Note remains outstanding, shall accrue at 4.25% per annum on the Issue Price, plus any previously accrued Original Issue Discount plus the amount of any Contingent Additional Principal, on a semi-annual bond equivalent basis using a 360-day year comprised of twelve 30-day months, from the Issue Date of this Note.

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 at Stated Maturity to Holders who surrender Notes to a Paying Agent to collect such payments in respect of the Notes. In addition, the Company will pay Contingent Cash Interest and Contingent Additional Principal, if any. The Company will pay 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, The Chase Manhattan Bank, a banking corporation organized and existing under the laws of the State of New York (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, except that the Company will maintain at least one Paying Agent in the

A-1-3


State of New York, City of New York, Borough of Manhattan, which shall initially be an office or agency of 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 has issued the Notes under an Indenture dated as of June 5, 2001 (the "Original Indenture"), between the Company and the Trustee, as supplemented by a first supplemental indenture, dated as of June 5, 2001 (the "Supplemental Indenture," and together with the Original Indenture, the "Indenture"). The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Notes themselves and the Trust 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 Notes are subject to all such terms, and Noteholders are referred to the Indenture and the TIA for a statement of those terms.

The Notes are unsecured and unsubordinated obligations of the Company limited to $408,000,000 aggregate Principal Amount at Maturity (not including Contingent Additional Principal, if any, and subject to Article 2 of the Supplemental Indenture) and will rank equally in right of payment to all the Company's present and future unsecured and unsubordinated indebtedness. The Indenture does not limit other indebtedness of the Company, secured or unsecured.

5.A Contingent Cash Interest.

Subject to the conditions of the Indenture and the accrual and record date provisions specified in this paragraph 5.A, the Company shall pay Contingent Cash Interest to the Holders during any six-month period (a "Contingent Cash Interest Period") from June 6 to December 5 and from December 6 to June 5, with the initial six-month period commencing after June 5, 2006, if the average LYONs Market Price for the Five-Trading-Day Measurement Period with respect to such Contingent Cash Interest Period equals 120% or more of the sum of the Issue Price of a Note, Original Issue Discount accrued thereon to the day immediately preceding the first day of the relevant Contingent Interest Period and Contingent Additional Principal, if any, for such Note to the day immediately preceding the first day of the applicable six-month period.

Contingent Cash Interest, if any, will accrue and be payable to holders of this Note as of the 15th day preceding the last day of the applicable six-month period. Original Issue Discount will continue to accrue at 4.25% whether or not Contingent Cash Interest is paid.

The amount of Contingent Cash Interest payable per $1,000 Principal Amount at Maturity hereof in respect of any quarterly period of the applicable Contingent Cash Interest Period shall equal the greater of (x) 0.0625% of the average LYONs Market Price for the relevant Five-Trading-Day Measurement Period and (y) the sum of all Regular Cash Dividends paid by the Company per share of Common Stock during that three-month period of the applicable Contingent Cash Interest Period multiplied by the number of shares of Common Stock into which

A-1-4


$1,000 Principal Amount at Maturity hereof is convertible pursuant to paragraph 9 hereof as of the accrual date for such Contingent Cash Interest.

Upon determination that Holders will be entitled to receive Contingent Cash Interest during a Contingent Cash Interest Period the Company shall issue a press release and publish such information on its web site on the World Wide Web as soon as practicable.

5.B Contingent Additional Principal

Subject to the conditions set forth in the Indenture, on June 5, 2002 and June 5, 2004, if the Sale Price of the Common Stock is at or below the Threshold Price (as set forth in Section 601 of the Supplemental Indenture) for the Thirty-Trading-Day Measurement Period prior to that date, Contingent Additional Principal on the Notes shall accrue commencing on such date at a rate of either 0.50% or 1.00% per annum for a period of two years, in accordance with the schedule set forth in Section 601 of the Supplemental Indenture. No Contingent Additional Principal will accrue after June 5, 2006.

Contingent Additional Principal, if any, shall be payable on the Stated Maturity date of the Notes. Contingent Additional Principal shall be calculated on a semiannual bond equivalent basis, using a 360-day year consisting of twelve 30-day months.

In the event that any Contingent Additional Principal accrues on the Notes, the Company shall issue a press release to that effect. In addition, the Company shall publish such information on its website or through such other comparable public medium as may be widely in use at that time. The Company shall also notify the Trustee annually in writing, at such time that the Company files with the Trustee its annual reports or other information or documents pursuant to Section 704 of the Original Indenture, of any accrual of Contingent Additional Principal and the resulting increase in the Principal Amount at Maturity per Note. Following its receipt of such notice, the Trustee shall provide such information to DTC for dissemination to the participants of DTC.

Subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase, at the option of the Holder, the Notes held by such Holder on the following Purchase Dates and at the following Purchase Prices, plus Contingent Additional Principal, if any, 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 at least 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 Notes to the Paying Agent by the Holder as set forth in the Indenture.

Purchase Date              Purchase Price
-------------              --------------
June 5, 2002                   $295.35
June 5, 2004                   $321.27
June 5, 2006                   $349.46
June 5, 2011                   $431.24
June 5, 2016                   $532.16
June 5, 2021                   $659.69
June 5, 2026                   $810.36

The Purchase Price 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 all or a portion of the Notes in integral multiples of $1,000 Principal Amount at Maturity held by such Holder no later than 35 Business Days after the occurrence of a Change in Control of the Company occurring on or prior to June 5, 2006 for a Change in Control Purchase Price for each $1,000 Principal Amount at Maturity of such Notes 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.

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 within the times and otherwise 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 all Notes 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, Contingent Cash Interest, if any, and Contingent Additional Principal, if any, shall cease to accrue on such Notes (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, if any, upon surrender of such Note).

A-1-7


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 Notes to be redeemed at the Holder's registered address. If money sufficient to pay the Redemption Price of all Notes (or portions thereof) to be redeemed on the Redemption Date is deposited with the Paying Agent prior to or on the Redemption Date, immediately after such Redemption Date, Original Issue Discount and Contingent Cash Interest, if any, shall cease to accrue on such Notes or portions thereof. Notes 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 and the terms of the Indenture and notwithstanding the fact that any other condition to conversion has not been satisfied, Holders may surrender this Note for conversion into shares of Common Stock at any time at their option until the close of business on the Business Day immediately preceding June 5, 2031 if, as of the last day of any calendar quarter beginning with the quarter ending on September 30, 2001, 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 quarter is more than the conversion trigger price. The "conversion trigger price" is a reference percentage beginning at 120% and declining 0.08474% per quarter thereafter to approximately 110% on the last day of the quarter ending March 31, 2031, of the accreted conversion price per share of Common Stock on the last day of such quarter. Notes subject to conversion pursuant to the condition to conversion contained in this paragraph will remain convertible notwithstanding changes to the Sale Price of the Common Stock after such Notes are deemed convertible.

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

o the Issue Price plus accrued Original Issue Discount to that day and any accrued Contingent Additional Principal, divided by

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

The table below shows the conversion trigger price per share of Common Stock in respect of each of the first 20 calendar quarters. These prices reflect the accreted conversion price per share of Common Stock (assuming that no events occurred requiring an adjustment to the initial Conversion Rate of 1.1629 shares of Common Stock per $1,000 Principal Amount at Maturity) multiplied by the applicable percentage for the respective calendar quarter. Thereafter, the accreted conversion price per share of Common Stock increases each calendar quarter by the accrued Original Issue Discount and any Contingent Additional Principal for the quarter and the applicable percentage declines by 0.08474% per quarter. The conversion trigger price for the calendar quarter beginning April 1, 2031 is $938.92.

* This table assumes no events have occurred that would require an adjustment to the conversion rate. Also assumes that no Contingent Additional Principal has been accrued.

Subject to the provisions of this paragraph 9 and the Indenture and notwithstanding the fact any other condition to conversion has not been satisfied, Holders may convert the Notes into Common Stock on a Conversion Date during any period in which the credit rating assigned to the Notes by a Rating Agency is reduced to or below the Applicable Rating. "Rating Agency" means (1) Moody's Investors Service, Inc. and its successors ("Moody's") and (2) Standard & Poor's Credit Market Services, a division of The McGraw-Hill Companies Inc., and its successors ("Standard & Poor's"). "Applicable Rating" means (1) Ba3, in the case of Moody's (or its equivalent under any successor ratings categories of Moody's), (2) BB-, in the case of Standard & Poor's (or its equivalent under any successor ratings categories of Standard & Poor's) or (3) the equivalent in respect of ratings categories of any Rating Agencies which are successors to Moody's or Standard & Poor's.

A-1-9


Subject to the provisions of this paragraph 9 and the Indenture and notwithstanding the fact that any other condition to conversion has not been satisfied, a Holder may convert into Common Stock a Note or portion of a Note which has been called for redemption pursuant to paragraph 6 hereof, even if the Note, or any portion thereof, is not subject to conversion by the Holder, provided such Notes are surrendered for conversion prior to the close of business on the second Business Day immediately preceding the Redemption Date.

Subject to the provisions of this paragraph 9 and the Indenture and notwithstanding the fact that any other condition to conversion has not been satisfied, in the event that the Company declares a dividend or distribution described in Section 407 of the Supplemental Indenture, or a dividend or a distribution described in Section 408 of the Supplemental Indenture where the fair market value of such dividend or distribution per share of Common Stock, as determined in the Indenture, exceeds 15% of the Sale Price of the Common Stock on the Trading Day immediately preceding the date of declaration for such dividend or distribution, the Notes may be surrendered for conversion beginning on the date the Company gives notice to the Holders of such right, which shall not be less than 20 days prior to the Ex-Dividend Time for such dividend or distribution, and Notes may be surrendered for conversion at any time thereafter until the close of business on the Business Day prior to the Ex-Dividend Time or until the Company announces that such dividend or distribution will not take place.

Subject to the provisions of this paragraph 9 and the Indenture and notwithstanding the fact that any other condition to conversion has not been satisfied, in the event the Company is a party to a consolidation, merger or binding share exchange pursuant to which the Common Stock would be converted into cash, securities or other property as set forth in Section 414 of the Supplemental Indenture, the Notes may be surrendered for conversion at any time from and after the date which is 15 days prior to the date of the anticipated effective time of such transaction announced by the Company until 15 days after the actual effective date of such transaction, and at the effective time of such transaction the right to convert a Note 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 property which the holder would have received if the holder had converted its Note immediately prior to the transaction.

A Note 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 Note may be converted only if such notice of exercise is withdrawn in accordance with the terms of the Indenture.

The initial Conversion Rate is 1.1629 shares of Common Stock per $1,000 Principal Amount at Maturity, subject to adjustment for certain events described in the Indenture or this paragraph 9. The Company will deliver cash or a check in lieu of any fractional share of Common Stock.

Contingent Additional Principal, if any, will not be paid on Notes that are converted. Contingent Cash Interest, if any, will not be paid on Notes that are converted; provided, however, that Notes surrendered for conversion during the period from the close of business on any date on which Contingent Cash Interest accrues to the opening of business on the date on which such Contingent Cash Interest is payable shall be entitled to receive such Contingent Cash Interest payable on such Notes on the date on which such Contingent Cash Interest is

A-1-10


payable and (except Notes with respect to which the Company has mailed a notice of redemption) Notes surrendered for conversion during such periods must be accompanied by payment of an amount equal to the Contingent Cash Interest with respect thereto that the registered Holder is to receive.

To convert a Note, 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 Note 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.

A Holder may only convert a portion of a Note pursuant to the terms of this paragraph 9 and in accordance with the Indenture 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 herein and in the Indenture. On conversion of a Note, that portion of accrued Tax Original Issue Discount, accrued Original Issue Discount and Contingent Additional Principal, if any, attributable to the period from the Issue Date through the Conversion Date and (except as provided above) accrued Contingent Cash Interest with respect to the converted Note 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) in exchange for the Note 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) shall be treated as issued, to the extent thereof, first in exchange for accrued Tax Original Issue Discount, Original Issue Discount and accrued Contingent Additional Principal, if any, through the Conversion Date and accrued Contingent Cash Interest, and the balance, if any, of such fair market value of such Common Stock (and any such cash payment) shall be treated as issued in exchange for the Issue Price of the Note being converted pursuant to the provisions hereof.

Pursuant to the terms and conditions of the Indenture, 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 at less than the Sale Price of the Common Stock at the Time of Determination; and distributions to such holders of assets 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 Noteholders 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 Note into Common Stock may be changed into a right to convert it into securities, cash or other assets of the Company or another person.

The Conversion Rate will not be adjusted for accrued Original Issue Discount, any Contingent Additional Principal or any Contingent Cash Interest.

A-1-11


10. Defaulted Interest.

Except as otherwise specified with respect to the Notes, any Contingent Cash Interest on any Note shall forthwith cease to be payable to the registered Holder thereof on the relevant Regular Record Date or accrual date, as the case may be, by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company as provided for in Section 502 of the Supplemental Indenture.

11. Denominations; Transfer; Exchange.

The Notes 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 Notes 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 of or exchange any Notes selected for redemption (except, in the case of a Note to be redeemed in part, the portion of the Note not to be redeemed) or any Notes 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 Note to be purchased in part, the portion of the Note not to be purchased) or any Notes for a period of 15 days before the mailing of a notice of redemption of Notes to be redeemed.

12. Persons Deemed Owners.

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

13. 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 Notes 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.

14. Amendment; Waiver.

Subject to certain exceptions set forth in the Indenture, (i) the Indenture or the Notes may be amended with the written consent of the Holders of at least a majority in aggregate Principal Amount at Maturity of the Notes 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 Notes at the time outstanding. Subject to certain exceptions set forth in the Indenture, without the consent of any Noteholder, the Company and the Trustee may amend the Indenture or the Notes to cure any ambiguity, omission, defect or inconsistency, or to comply with certain provisions of the Indenture, to secure the Company's obligations under this Note, to add to the Company's covenants for the benefit of the Noteholders, to surrender any right or power conferred, to make any change that does not adversely affect the rights of any Noteholder, or to comply with any requirement of the SEC in connection with the qualification of the Indenture under the TIA, or as necessary in connection with the registration of the Notes under the Securities Act.

A-1-12


15. Defaults and Remedies.

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 Notes at the time outstanding, may declare all the Notes to be due and payable immediately. Certain events of bankruptcy or insolvency are Events of Default that will result in the Notes becoming due and payable immediately upon the occurrence of such Events of Default.

Noteholders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Notes 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 Notes at the time outstanding may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Noteholders notice of any continuing Event of Default (except an Event of Default in payment of amounts specified in Section 501(a) or Section 501(b) of the Original Indenture, as amended by Article 7 of the Supplemental Indenture) if it determines that withholding notice is in their interests.

16. 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 Notes and may otherwise deal with and collect obligations owed to it by the Company or its respective Affiliates and may otherwise deal with the Company or its respective Affiliates with the same rights it would have if it were not Trustee.

17. 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 Notes or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Note, each Noteholder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Notes.

18. Authentication.

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

19. Abbreviations.

Customary abbreviations may be used in the name of a Noteholder 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).

[REVERSE SIDE OF CERTIFICATED NOTE]

Liquid Yield Option(TM) Note due 2031
(Zero Coupon-Senior)

1. Interest.

This Note shall not bear interest, except as specified in this paragraph or in paragraph 5.A 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 502 of the Original Indenture, as amended by Article 7 of the Supplemental 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 Note) or if Contingent Cash Interest, if any, due hereon or any portion of such Contingent Cash Interest is not paid when due in accordance with paragraph 5.A hereof, or if Contingent Additional Principal, if any, due hereon or any portion of such Contingent Additional Principal is not paid when due in accordance with paragraph 5.B hereof, then in each such case the overdue amount shall, to the extent permitted by law, bear interest at the rate of 4.25% per annum, compounded semi-annually, 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 Note), in the period during which a Note remains outstanding, shall accrue at 4.25% per annum on the Issue Price, plus any previously accrued Original Issue Discount plus the amount of any Contingent Additional Principal, on a semi-annual bond equivalent basis using a 360-day year comprised of twelve 30-day months, from the Issue Date of this Note.

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 at Stated Maturity to Holders who surrender Notes to a Paying Agent to collect such payments in respect of the Notes. In addition, the Company will pay Contingent Cash Interest and Contingent Additional Principal, if any. The Company will pay 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, The Chase Manhattan Bank, a banking corporation organized and existing under the laws of the State of New York (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, except that the Company will maintain at least one Paying Agent in the

A-2-3


State of New York, City of New York, Borough of Manhattan, which shall initially be an office or agency of 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 has issued the Notes under an Indenture dated as of June 5, 2001 (the "Original Indenture"), between the Company and the Trustee, as supplemented by a first supplemental indenture, dated as of June 5, 2001 (the "Supplemental Indenture," and together with the Original Indenture, the "Indenture"). The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Notes themselves and the Trust 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 Notes are subject to all such terms, and Noteholders are referred to the Indenture and the Trust Indenture Act for a statement of those terms.

The Notes are unsecured and unsubordinated obligations of the Company limited to $408,000,000 aggregate Principal Amount at Maturity (not including Contingent Additional Principal, if any, and subject to Article 2 of the Supplemental Indenture) and will rank equally in right of payment to all the Company's present and future unsecured and unsubordinated indebtedness. The Indenture does not limit other indebtedness of the Company, secured or unsecured.

5.A Contingent Cash Interest.

Subject to the conditions of the Indenture and the accrual and record date provisions specified in this paragraph 5.A, the Company shall pay Contingent Cash Interest to the Holders during any six-month period (a "Contingent Cash Interest Period") from June 6 to December 5 and from December 6 to June 5, with the initial six-month period commencing after June 5, 2006, if the average LYONs Market Price for the Five-Trading-Day Measurement Period with respect to such Contingent Cash Interest Period equals 120% or more of the sum of the Issue Price of a Note, Original Issue Discount accrued thereon to the day immediately preceding the first day of the relevant Contingent Interest Period and Contingent Additional Principal, if any, for such Note to the day immediately preceding the first day of the applicable six-month period.

Contingent Cash Interest, if any, will accrue and be payable to holders of this Note as of the 15th day preceding the last day of the applicable six-month period. Original Issue Discount will continue to accrue at 4.25% whether or not Contingent Cash Interest is paid.

The amount of Contingent Cash Interest payable per $1,000 Principal Amount at Maturity hereof in respect of any quarterly period of the applicable Contingent Cash Interest Period shall equal the greater of (x) 0.0625% of the average LYONs Market Price for the relevant Five-Trading-Day Measurement Period and (y) the sum of all Regular Cash Dividends paid by the Company per share of Common Stock during that three-month period of the applicable Contingent Cash

A-2-4


Interest 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 Cash Interest.

Upon determination that Holders will be entitled to receive Contingent Cash Interest during a Contingent Cash Interest Period the Company shall issue a press release and publish such information on its web site on the World Wide Web as soon as practicable.

5.B Contingent Additional Principal

Subject to the conditions set forth in the Indenture, on June 5, 2002 and June 5, 2004, if the Sale Price of the Common Stock is at or below the Threshold Price (as set forth in Section 601 of the Supplemental Indenture) for the Thirty-Trading-Day Measurement Period prior to that date, Contingent Additional Principal on the Notes shall accrue commencing on such date at a rate of either 0.50% or 1.00% per annum for a period of two years, in accordance with the schedule set forth in Section 601 of the Supplemental Indenture. No Contingent Additional Principal will accrue after June 5, 2006.

Contingent Additional Principal, if any, shall be payable on the Stated Maturity date of the Notes. Contingent Additional Principal shall be calculated on a semiannual bond equivalent basis, using a 360-day year consisting of twelve 30-day months.

In the event that any Contingent Additional Principal accrues on the Notes, the Company shall issue a press release to that effect. In addition, the Company shall publish such information on its website or through such other comparable public medium as may be widely in use at that time. The Company shall also notify the Trustee annually in writing, at such time that the Company files with the Trustee its annual reports or other information or documents pursuant to Section 704 of the Original Indenture, of any accrual of Contingent Additional Principal and the resulting increase in the Principal Amount at Maturity per Note. Following its receipt of such notice, the Trustee shall provide such information to DTC for dissemination to the participants of DTC.

6. Redemption at the Option of the Company.

No sinking fund is provided for the Notes. The Notes are redeemable as a whole, or from time to time in part, at any time at the option of the Company at the Redemption Prices set forth below, provided that the Notes are not redeemable prior to June 5, 2006.

The table below shows Redemption Prices of a Note per $1,000 Principal Amount at Maturity on the dates shown below and at Stated Maturity, which prices reflect the Issue Price plus accrued Original Issue Discount calculated to each such date and assumes that no Contingent Additional Principal is payable. The Redemption Price of a Note redeemed between such dates shall include an additional amount reflecting the additional Original Issue Discount accrued since the next preceding date in the table and accrued Contingent Additional Principal, if applicable.

Purchase Date       Purchase Price
-------------       --------------
June 5, 2002           $295.35
June 5, 2004           $321.27
June 5, 2006           $349.46
June 5, 2011           $431.24
June 5, 2016           $532.16
June 5, 2021           $659.69
June 5, 2026           $810.36

The Purchase Price 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 all or a portion of the Notes in integral multiples of $1,000 Principal Amount at Maturity held by such Holder no later than 35 Business Days after the occurrence of a Change in Control of the Company occurring on or prior to June 5, 2006 for a Change in Control Purchase Price for each $1,000 Principal Amount at Maturity of such Notes 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.

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 within the times and otherwise 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 all Notes 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, Contingent Cash Interest, if any, and Contingent Additional Principal, if any, shall cease to accrue on such Notes (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, if any, upon surrender of such Note).

A-2-7


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 Notes to be redeemed at the Holder's registered address. If money sufficient to pay the Redemption Price of all Notes (or portions thereof) to be redeemed on the Redemption Date is deposited with the Paying Agent prior to or on the Redemption Date, immediately after such Redemption Date, Original Issue Discount and Contingent Cash Interest, if any, shall cease to accrue on such Notes or portions thereof. Notes 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 and the terms of the Indenture and notwithstanding the fact that any other condition to conversion has not been satisfied, Holders may surrender this Note for conversion into shares of Common Stock at any time at their option until the close of business on the Business Day immediately preceding June 5, 2031 if, as of the last day of any calendar quarter beginning with the quarter ending on September 30, 2001, 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 quarter is more than the conversion trigger price. The "conversion trigger price" is a reference percentage beginning at 120% and declining 0.08474% per quarter thereafter to approximately 110% on the last day of the quarter ending March 31, 2031, of the accreted conversion price per share of Common Stock on the last day of such quarter. Notes subject to conversion pursuant to the condition to conversion contained in this paragraph will remain convertible notwithstanding changes to the Sale Price of the Common Stock after such Notes are deemed convertible.

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

o the Issue Price plus accrued Original Issue Discount to that day and any accrued Contingent Additional Principal, divided by

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

The table below shows the conversion trigger price per share of Common Stock in respect of each of the first 20 calendar quarters. These prices reflect the accreted conversion price per share of Common Stock (assuming that no events occurred requiring an adjustment to the initial Conversion Rate of 1.1629 shares of Common Stock per $1,000 Principal Amount at Maturity) multiplied by the applicable percentage for the respective calendar quarter. Thereafter, the accreted conversion price per share of Common Stock increases each calendar quarter by the accrued Original Issue Discount and any Contingent Additional Principal for the quarter and the applicable percentage declines by 0.08474% per quarter. The conversion trigger price for the calendar quarter beginning April 1, 2031 is $938.92.

Subject to the provisions of this paragraph 9 and the Indenture and notwithstanding the fact that any other condition to conversion has not been satisfied, a Holder may convert into Common Stock a Note or portion of a Note which has been called for redemption pursuant to paragraph 6 hereof, even if the Note, or any portion thereof, is not subject to conversion by the Holder, provided such Notes are surrendered for conversion prior to the close of business on the second Business Day immediately preceding the Redemption Date.

Subject to the provisions of this paragraph 9 and the Indenture and notwithstanding the fact that any other condition to conversion has not been satisfied, in the event that the Company declares a dividend or distribution described in Section 407 of the Supplemental Indenture, or a dividend or a distribution described in Section 408 of the Supplemental Indenture where the fair market value of such dividend or distribution per share of Common Stock, as determined in the Indenture, exceeds 15% of the Sale Price of the Common Stock on the Trading Day immediately preceding the date of declaration for such dividend or distribution, the Notes may be surrendered for conversion beginning on the date the Company gives notice to the Holders of such right, which shall not be less than 20 days prior to the Ex-Dividend Time for such dividend or distribution, and Notes may be surrendered for conversion at any time thereafter until the close of business on the Business Day prior to the Ex-Dividend Time or until the Company announces that such dividend or distribution will not take place.

Subject to the provisions of this paragraph 9 and the Indenture and notwithstanding the fact that any other condition to conversion has not been satisfied, in the event the Company is a party to a consolidation, merger or binding share exchange pursuant to which the Common Stock would be converted into cash, securities or other property as set forth in Section 414 of the Supplemental Indenture, the Notes may be surrendered for conversion at any time from and after the date which is 15 days prior to the date of the anticipated effective time of such transaction announced by the Company until 15 days after the actual effective date of such transaction, and at the effective time of such transaction the right to convert a Note 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 property which the holder would have received if the holder had converted its Note immediately prior to the transaction.

A Note 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 Note may be converted only if such notice of exercise is withdrawn in accordance with the terms of the Indenture.

The initial Conversion Rate is 1.1629 shares of Common Stock per $1,000 Principal Amount at Maturity, subject to adjustment for certain events described in the Indenture or this paragraph 9. The Company will deliver cash or a check in lieu of any fractional share of Common Stock.

Contingent Additional Principal, if any, will not be paid on Notes that are converted. Contingent Cash Interest, if any, will not be paid on Notes that are converted; provided, however, that Notes surrendered for conversion during the period from the close of business on any date on which Contingent Cash Interest accrues to the opening of business on the date on which such Contingent Cash

A-2-10


Interest is payable shall be entitled to receive such Contingent Cash Interest payable on such Notes on the date on which such Contingent Cash Interest is payable and (except Notes with respect to which the Company has mailed a notice of redemption) Notes surrendered for conversion during such periods must be accompanied by payment of an amount equal to the Contingent Cash Interest with respect thereto that the registered Holder is to receive.

To convert a Note, 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 Note 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.

A Holder may only convert a portion of a Note pursuant to the terms of this paragraph 9 and in accordance with the Indenture 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 herein and in the Indenture. On conversion of a Note, that portion of accrued Tax Original Issue Discount, accrued Original Issue Discount and Contingent Additional Principal, if any, attributable to the period from the Issue Date through the Conversion Date and (except as provided above) accrued Contingent Cash Interest with respect to the converted Note 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) in exchange for the Note 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) shall be treated as issued, to the extent thereof, first in exchange for accrued Tax Original Issue Discount, accrued Original Issue Discount and accrued Contingent Additional Principal, if any, through the Conversion Date and accrued Contingent Cash Interest, and the balance, if any, of such fair market value of such Common Stock (and any such cash payment) shall be treated as issued in exchange for the Issue Price of the Note being converted pursuant to the provisions hereof.

Pursuant to the terms and conditions of the Indenture, 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 at less than the Sale Price of the Common Stock at the Time of Determination; and distributions to such holders of assets 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 Noteholders 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 Note into Common Stock may be changed into a right to convert it into securities, cash or other assets of the Company or another person.

The Conversion Rate will not be adjusted for accrued Original Issue Discount, any Contingent Additional Principal or any Contingent Cash Interest.

A-2-11


10. Defaulted Interest.

Except as otherwise specified with respect to the Notes, any Contingent Cash Interest on any Note shall forthwith cease to be payable to the registered Holder thereof on the relevant Regular Record Date or accrual date, as the case may be, by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company as provided for in Section 502 of the Supplemental Indenture.

11. Denominations; Transfer; Exchange.

The Notes 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 Notes 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 of or exchange any Notes selected for redemption (except, in the case of a Note to be redeemed in part, the portion of the Note not to be redeemed) or any Notes 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 Note to be purchased in part, the portion of the Note not to be purchased) or any Notes for a period of 15 days before the mailing of a notice of redemption of Notes to be redeemed.

12. Persons Deemed Owners.

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

13. 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 Notes 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.

14. Amendment; Waiver.

Subject to certain exceptions set forth in the Indenture, (i) the Indenture or the Notes may be amended with the written consent of the Holders of at least a majority in aggregate Principal Amount at Maturity of the Notes 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 Notes at the time outstanding. Subject to certain exceptions set forth in the Indenture, without the consent of any Noteholder, the Company and the Trustee may amend the Indenture or the Notes to cure any ambiguity, omission, defect or inconsistency, or to comply with certain provisions of the Indenture, to secure the Company's obligations under this Note, to add to the Company's covenants for the benefit of the Noteholders, to surrender any right or power conferred, to make any change that does not adversely affect the rights of any Noteholder, or to comply with any requirement of the SEC in connection with the qualification of the Indenture under the TIA, or as necessary in connection with the registration of the Notes under the Securities Act.

A-2-12


15. Defaults and Remedies.

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 Notes at the time outstanding, may declare all the Notes to be due and payable immediately. Certain events of bankruptcy or insolvency are Events of Default that will result in the Notes becoming due and payable immediately upon the occurrence of such Events of Default.

Noteholders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Notes 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 Notes at the time outstanding may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Noteholders notice of any continuing Event of Default (except an Event of Default in payment of amounts specified in Section 501(a) or Section 501(b) of the Original Indenture, as amended by Article 7 of the Supplemental Indenture) if it determines that withholding notice is in their interests.

16. 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 Notes and may otherwise deal with and collect obligations owed to it by the Company or its respective Affiliates and may otherwise deal with the Company or its respective Affiliates with the same rights it would have if it were not Trustee.

17. 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 Notes or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Note, each Noteholder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Notes.

18. Authentication.

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

19. Abbreviations.

Customary abbreviations may be used in the name of a Noteholder 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).

Ladies and Gentlemen:

We have advised Markel Corporation, a Virginia corporation (the "Company"), in connection with (i) the Registration on Form S-3 as amended (File No. 333- 52544) (the "Registration Statement") filed by the Company with the Securities and Exchange Commission for the purpose of offering under the Securities Act of 1933, as amended, the Company's debt securities, debt warrants, common stock, common stock warrants, preferred stock, preferred stock warrants and depositary shares to be offered from time to time by the Company on terms to be determined at the time of the offering and (ii) the issuance of the Company of up to $408,000,000 aggregate principal amount, including the underwriters overallotment of $53,000,000, of the Company's 4.25% Liquid Yield Option Notes due 2031 (the "Notes") as described in the Company's Prospectus Supplement, dated May 30, 2001 (the "Prospectus Supplement"), and pursuant to an indenture, dated June 5, 2001, between the Company and The Chase Manhattan Bank, as trustee (the "Trustee"), as supplemented by a First Supplemental Indenture, dated as of June 5, 2001 (the "Indenture"), and the public offering of the Notes pursuant to an Underwriting Agreement, dated May 30, 2001 (the "Underwriting Agreement"), between the Company and Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated. Capitalized terms used and not defined herein shall have the meanings assigned to them in the Prospectus Supplement or the Indenture.

We have examined such corporate records, certificates and other documents, and reviewed such questions of law, as we have considered necessary or appropriate for the purpose of this opinion.

On the basis of such examination and review, we advise you that, in our opinion, when the Notes have been duly issued and sold in the manner contemplated by the Registration Statement and the Prospectus Supplement, and assuming due authentication thereof by the Trustee in accordance with the provision of the Indenture, the Notes will constitute valid and legally binding obligations of the Company, enforceable against the Company in accordance with their terms, subject to bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfers), reorganization, moratorium or similar laws affecting creditor's rights generally and to general principles of equity (regardless of whether enforcement is considered in a proceeding in equity or at law).


We hereby consent to the filing as exhibits to the Company's Current Report on Form 8-K of this opinion and our opinion dated the date hereof with respect to tax matters filed as Exhibit 8 to such Current Report on Form 8-K and to their incorporation by reference in the Registration Statement. We also hereby consent to the references to us under the heading "Legal Matters" in the Registration Statement and the heading "Validity of the LYONs" in the Prospectus Supplement. In giving this consent, we do not admit that we are in the category of persons whose consent is required by Section 7 of the Securities Act of 1933, as amended, or the rules and regulations promulgated thereunder by the Securities and Exchange Commission.

Very truly yours,

/s/ McGuireWoods LLP

Liquid Yield Option Notes Due 2031

Ladies and Gentlemen:

We have acted as counsel to Markel Corporation ("Markel") in connection with the issuance by it of its Liquid Yield Option Notes due 2031 (the "LYONs") in an aggregate principal amount at maturity of up to $408,000,000 as described in Markel's prospectus supplement dated May 30, 2001 (the Prospectus Supplement"). The LYONs will be issued pursuant to an indenture and supplemental indenture, each dated as of June 5, 2001 (collectively, the "Indenture"), between Markel and the Chase Manhattan Bank as indenture trustee.

You have asked that we render this opinion to you regarding certain aspects of the United States federal income tax classification of the LYONs and certain other United States federal income tax matters. Capitalized terms used in this opinion and not otherwise defined shall have the meanings specified in the Prospectus Supplement.

In preparing this opinion, we have examined, and with your permission relied on, such documents as we have deemed appropriate, including, inter alia, the Prospectus Supplement, the Indenture, a specimen of the LYONs, a representation letter from Markel setting forth certain factual matters relating to the above-referenced transaction and attached to this letter as Exhibit A, the originals or copies, certified or otherwise identified to our satisfaction, of all such corporate records of Markel and such other instruments, certificates and other documents of public officials and such other persons (the "Opinion Documents"), and we have made such investigations of law, as we have deemed appropriate as a basis for the opinion expressed below.

In rendering this opinion, with your permission, we have not undertaken any independent investigation or verification of any fact or other matter set forth in the documents and other materials on which we have relied or the assumptions set forth in this opinion, and we expressly disclaim any intent, undertaking, or obligation to make any such investigation or verification. We express no opinion with respect to the accuracy of the assumptions, certificates, or items upon which we have relied.

This opinion is expressly conditioned on the accuracy and completeness of the information listed in the preceding paragraphs, and is based upon the following additional assumptions:

(1) All documents and other materials submitted to us as originals and the signatures thereon are authentic, and those submitted to us as certified, conformed, photostatic, or telefaxed copies conform to the originals thereof. Each document required to be executed in connection with the issuance of the LYONs will be timely executed and a copy thereof delivered to us in final form which will not differ in any material respect from the form which was examined by us.

(2) All Persons signing each of the Opinion Documents were validly authorized to do so, and each document constitutes the legal, valid and binding obligation of each party to such document, and each is enforceable against the parties thereto in accordance with its terms.

(3) The LYONs will be issued in compliance with the requirements and terms of the Indenture and the other documents, and the affairs of the parties to the documents have been and will be conducted in a manner consistent with the requirements and terms of such documents.

(4) All representations contained in the Opinion Documents and other materials upon which we have relied are and will be true, correct and complete, and all representations contained therein that are made "to the best knowledge" of any person or party, or with similar qualification, are and will be true, correct and complete as if made without such qualification.

(5) In the initial sale of the LYONs, no more than 10% of the LYONs will be issued or transferred to or for the benefit of any stockholders of Markel who collectively own, actually or beneficially, more than 10% of the stock of Markel, or to persons that have a plan or intention to resell or transfer the LYONs to such stockholders of Markel.

Based on the foregoing; considerations of such other matters as we have deemed appropriate; Markel's representations, including without limitation that, as of the issue date, the likelihood that the contingent interest payments will be made during the term of the LYONs is not remote, and that, as of the issue

date, the likelihood that the contingent interest payments will not be made during the term of the LYONs is not remote; and certain estimates made by Markel and Merrill Lynch Pierce Fenner & Smith Incorporated regarding the present value of contingent payments, we are of the opinion that:

(1) the LYONs will be treated as indebtedness for United States federal income tax purposes;

(2) the statements in the Prospectus Supplement under the caption "Certain United States Federal Income Tax Consequences" insofar as such statements constitute a summary of the United States federal income tax laws referred to therein are accurate and fairly summarize the United States federal income tax laws referred to therein;

(3) the LYONs will be subject to the noncontingent bond method of the original issue discount regulations governing contingent payment debt instruments (section 1.1275-4(b) of the U. S. Treasury Regulations); and

(4) the term "comparable yield" means the annual yield Markel would pay, as of the initial issue date, on a fixed-rate nonconvertible debt security, with no contingent payments, but with terms and conditions otherwise comparable to those of the LYONs; however, the precise manner of calculating the comparable yield is not absolutely clear.

Depending on the identity of the persons to whom the LYONs were marketed or sold, there may be a presumption that the comparable yield is the applicable federal rate based on the overall maturity of the LYONs. This presumption may only be overcome with clear and convincing evidence that the comparable yield should be some yield other than the applicable federal rate.

Our opinion is based on the relevant provisions of the Internal Revenue Code of 1986, as amended (the "Code"), administrative rulings and pronouncements issued by the IRS, judicial decisions rendered by United States federal courts of competent jurisdiction, and Treasury Regulations in effect on the date of this opinion. These authorities are subject to change, possibly on a retroactive basis. This opinion will not be updated for subsequent changes or modifications to the law and regulations or to the judicial and administrative interpretations thereof unless we are specifically engaged to do so. Our opinion neither relates to nor purports to cover the laws, regulations, or other legal authorities of any state, local, or foreign governmental authority, nor any tax or other governmental charge, other than United States federal income tax.

No ruling has or will be sought or obtained from the IRS regarding any of the matters on which we have opined. Moreover, an opinion of counsel is not binding upon the IRS or the courts and as such does not provide a guarantee of result. Thus, no assurance can be given that the IRS will not take positions contrary to those stated herein or that a court would not uphold such contrary positions, potentially with adverse tax consequences.

We express no opinions other than those expressed in this opinion. This opinion is rendered only to those to whom it is addressed and may not be relied on in connection with any transactions other than those contemplated in this letter. The opinion may not be relied on for any other purpose or used, circulated, quoted or otherwise referred to or relied on by any other person, firm, or corporation for any purpose, without our prior written consent, except that we hereby consent to the reference to our firm under the captions "Certain United States Federal Income Tax Considerations" and "Validity of the LYONs" in the Prospectus Supplement and to the filing of this opinion as an exhibit thereto. In giving this consent, we do not admit that we are in the category of persons whose consent is required by Section 7 of the Securities Act of 1933 or the rules and regulations promulgated thereunder by the Securities and Exchange Commission.
