Ladies and Gentlemen:

    Boise Cascade Corporation, a Delaware corporation (the "Company"), and the several Underwriters named in Schedule I hereto (the "Underwriters") propose, subject to the terms and conditions stated herein, to enter into the Purchase Contracts (the "Purchase Contracts") referred to in the Purchase Contract Agreement to be dated as of December 5, 2001 (the "Purchase Contract Agreement") between the Company and BNY Western Trust Company, as Purchase Contract Agent (the "Purchase Contract Agent"), underlying an aggregate of 3,000,000 7.50% Adjustable Conversion-rate Equity Security Units (the "Firm Securities"). In connection therewith, Boise Cascade Trust I (the "Trust"), a statutory business trust created under the Business Trust Act of the State of Delaware (the "Delaware Business Trust Act"), and the Company propose, subject to the terms and conditions herein, that the Trust issue and sell to the Underwriters 3,000,000 7.50% Preferred Securities (liquidation amount $50) (the "Preferred Securities") representing undivided preferred beneficial interests in the assets of the Trust, which will be guaranteed by the Company (the "Guarantee") as to the payment of distributions, and as to payments on liquidation or redemption, to the extent that the Trust has funds on hand legally available therefor, as set forth in a guarantee agreement (the "Guarantee Agreement") between the Company and BNY Western Trust Company, as trustee (the "Guarantee Trustee"). In connection with the Purchase Contract Agreement and pursuant to the Pledge Agreement, to be dated as of December 5, 2001 (the "Pledge Agreement"), among the Company, the Purchase Contract Agent and JPMorgan Chase Bank, as collateral agent, custodial agent and securities intermediary (the "Collateral Agent"), the Preferred Securities underlying the Units (as defined below) will be pledged by the Purchase Contract Agent on behalf of the holders of the Units to secure the holders' obligations to the Company under the Purchase Contract underlying such Unit. The rights to purchase newly issued common stock, par value $2.50 per share, of the Company (the "Common Stock") under a Purchase Contract, together with the Preferred Securities or other pledged securities securing such Purchase Contract, subject to (i) the obligations owed to the Company under such Purchase Contract and (ii) the pledge arrangements under the Pledge Agreement securing the foregoing obligations, collectively constitute an Adjustable Conversion-rate Equity Security Unit (each, a "Unit"). In addition, subject to the terms and conditions herein, the Company proposes to grant the Underwriters an option to enter into Purchase Contracts underlying up to 450,000 additional Units, and the Trust and the Company propose to grant the Underwriters an option to purchase up to 450,000 additional Preferred Securities, and, in the event the Underwriters enter into any such additional Purchase Contracts, the Underwriters propose to purchase a number of additional Preferred Securities equal to such number of additional Purchase Contracts, pledge such Preferred Securities to the Collateral Agent (the Units resulting therefrom being the "Optional Securities"). The Firm Securities and any Optional Securities purchased by the Underwriters are herein called the "Securities".

    The proceeds of the sale of the Preferred Securities and of the common securities of the Trust (the "Common Trust Securities" and, together with the Preferred Securities, the "Trust Securities") to be sold by the Trust to the Company are to be invested in 7.50% Senior Debentures (the "Senior Debentures") of the Company to be issued pursuant to an Indenture (the "Original Indenture") between the Company and U.S. Bank Trust National Association (as successor in interest to Morgan Guaranty Trust Company of New York), as trustee (the "Original Trustee"), dated as of October 1, 1985, as supplemented by the First Supplemental Indenture between the Company and the Original Trustee, dated as of December 20, 1998 (the "First Supplement") and the Second Supplemental Indenture between the Company and the Original Trustee, dated as of August 1, 1990 (the "Second Supplement", and, together with the Original Indenture and the First Supplement, the "Base Indenture"), as further supplemented for this transaction by the Third Supplemental Indenture, to be dated as of December 5, 2001 (the "Third Supplemental Indenture", and, together with the Base Indenture, the "Indenture"), among the Company, the Original Trustee and BNY Western Trust Company, as series trustee (the "Debenture Trustee"). The Trust Securities will be issued pursuant to, and will be governed by the Amended and Restated Declaration of Trust, dated as of December 5, 2001, (the "Declaration") among the Company, BNY Western Trust Company, as property trustee (the "Property Trustee"), The Bank of New York (Delaware), as Delaware Trustee (the "Delaware Trustee"), the Administrative Trustees named therein and the holders from time to time of the beneficial interests in the assets of the Trust. The Declaration, the Indenture and the Guarantee Agreement will be qualified under the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act").

    Pursuant to a Remarketing Agreement (the "Remarketing Agreement") to be entered into among the Company, the Purchase Contract Agent and a financial institution to be selected by the Company to act as reset agent and remarketing agent (together, the "Remarketing Agent"), the Preferred Securities or Senior Debentures will be remarketed, subject to certain terms and conditions.

13

Delivery, Arthur Andersen LLP shall have furnished to you a letter or letters, dated the respective dates of delivery thereof, in form and substance satisfactory to you;

14

    8.  (a) Each of the Company and the Trust, jointly and severally, 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 any Preliminary Prospectus, the Registration Statement or the Prospectus, 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, 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 neither the Company nor the Trust shall 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 any Preliminary Prospectus, the Registration Statement or the Prospectus or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company by any Underwriter through Goldman, Sachs & Co. expressly for use therein.

    (b) Each Underwriter will indemnify and hold harmless the Company and the Trust against any losses, claims, damages or liabilities to which the Company and the Trust 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 any Preliminary Prospectus, the Registration Statement or the Prospectus, 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 any Preliminary Prospectus, the Registration Statement or the Prospectus or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company by such Underwriter through Goldman, Sachs & Co. 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) or (b) 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 action or

15

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 a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

    (d) If the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) 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 and the Trust on the one hand and the Underwriters on the other from the offering of the Securities. 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 (c) 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 and the Trust on the one hand and the Underwriters 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 and the Trust on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company and the Trust bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. 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 or the Trust on the one hand or the 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, the Trust and the Underwriters agree that it would not be just and equitable if contribution pursuant to this subsection (d) 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 (d). 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 (d) 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 (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the 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 Underwriters' obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint.

    (e) The obligations of the Company and the Trust under this Section 8 shall be in addition to any liability which the Company or the Trust 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

16

terms and conditions, to each officer and director of the Company and to each person, if any, who controls the Company or the Trust within the meaning of the Act.

    9.  (a) If any Underwriter shall default in its obligation to purchase the Securities which it has agreed to purchase hereunder, you may in your discretion arrange for you or another party or other parties reasonably acceptable to the Company to purchase such Securities on the terms contained herein at a Time of Delivery. If within thirty-six hours after such default by any Underwriter you do not arrange for the purchase of such Securities, 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 you to purchase such Securities on such terms. In the event that, within the respective prescribed periods, you notify the Company that you have so arranged for the purchase of such Securities, or the Company notifies you that it has so arranged for the purchase of such Securities, you or the Company shall have the right to postpone such Time of Delivery 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, or in any other documents or arrangements, and the Company agrees to file promptly any amendments to the Registration Statement or the Prospectus which in your opinion 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 this Agreement with respect to such Securities.

    (b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by you and the Company as provided in subsection (a) above, the aggregate principal amount of such Securities which remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities to be purchased at such Time of Delivery, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Securities which such Underwriter agreed to purchase hereunder at such Time of Delivery and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the principal amount of Securities which such Underwriter agreed to purchase hereunder) of the Securities 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 Securities of a defaulting Underwriter or Underwriters by you and the Company as provided in subsection (a) above, the aggregate principal amount of Securities which remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities to be purchased at such Time of Delivery, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Securities of a defaulting Underwriter or Underwriters, then this Agreement (or, with respect to the Second Time of Delivery, the obligation of the Underwriters to purchase and of the Company to sell the Optional Securities) 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.

(iii)	to use its best efforts to cause the Trust to remain classified as a grantor trust and not an association taxable as a corporation for United States federal income tax purposes;

(v)	to use its best efforts to cause the Trust to remain a business trust under the Delaware Business Trust Act, as the same may be amended from time to time, except (a) in connection with a distribution of the Series Securities to the Holders of Preferred Securities in the event of an Early Termination Event or (b) in connection with such mergers, consolidations and amalgamations as are permitted by the Declaration;

(viii)	in the event that the Trust is dissolved and the Series Securities distributed to the holders of the Preferred Securities, to use its reasonable efforts to cause the Series Securities to be listed on a national securities exchange in the event that trading in and distribution of the Series Securities meets the minimum requirements with respect to listing.

The Company shall promptly notify the Trustee of any change in the CUSIP numbers.

The interest rate will be reset on the fourth Business Day preceding September 16, 2004 to the Reset Rate (as determined by the Reset Agent); provided, however, if there has been a Failed Remarketing, the Reset Rate will be equal to the Interest Rate until the Preferred Securities are successfully remarketed pursuant to the Purchase Contract Agreement. The amount of interest payable on any Interest Payment Date shall be computed on the basis of a 360-day year consisting of twelve 30-day months. In the event that any date on which interest is payable on this Debenture is not a Business Day, then payment of interest payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay), except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date. The interest installment so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to the person in whose name this Debenture is registered at the close of business on the regular record date for such interest installment, which in the case of a Global Debenture shall be the close of business on the Business Day next preceding such Interest Payment Date; provided, however, if pursuant to the terms of the Indenture the Debentures are no longer represented by a Global Debenture, the Company may select such regular record date for such interest installment which shall be more than one Business Day but less than 60 Business Days prior to an Interest Payment Date. Any such interest installment not punctually paid or duly provided for shall forthwith cease to be payable to the registered Holders on such regular record date and may be paid to the Person in whose name this Debenture is registered at the close of business on a special record date to be fixed by the Trustee for the payment of such defaulted interest, notice whereof shall be given to the registered Holders of this series of Debentures not less than 10 days prior to such special record date, or may be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Debentures may be listed, and upon such notice as may be required by such exchange all as more fully provided in the Indenture. The principal of and the interest on this Debenture shall be payable at the office or agency of the Trustee maintained for that purpose in any coin or currency of the United States of America that at the time of payment is legal tender for payment of public and private debts; provided, however, that payment of interest may be made at the option of the Company by check mailed to the registered Holder at such address as shall appear in the Register or by wire transfer to an account appropriately designated by the Holder entitled thereto. Notwithstanding the foregoing, so long as the Holder of this Debenture is the Property

12

Trustee or the Collateral Agent, the payment of the principal of and interest on this Debenture will be made at such place and to such account as may be designated in writing by the Property Trustee.

    This Debenture shall not be entitled to any benefit under the within mentioned Indenture, be valid or become obligatory for any purpose, until the Certificate of Authentication hereon shall have been executed by the Trustee.

    The provisions of this Debenture are continued on the reverse side hereof and such continued provisions shall for all purposes have the same effect as though fully set forth at this place.

(FORM OF REVERSE OF DEBENTURE)

    This Debenture is one of a duly authorized series of the debentures of the Company (herein sometimes referred to as the "Series Securities"), all issued or to be issued in one or more series under and pursuant to an Indenture, dated as of October 1, 1985 (the "Original Indenture"), between the Company and Morgan Guaranty Trust Company of New York (the "Original Trustee") as amended and supplemented by the First Supplemental Indenture (the "First Supplement"), dated as of December 20, 1989 between the Company and the Original Trustee, the Second Supplemental Indenture (the "Second Supplement"), dated as of August 1, 1990 between the Company and the Original Trustee and the Third Supplemental Indenture (the "Third Supplemental Indenture", and together with the Original Indenture and the First Supplement and the Second Supplement, the "Indenture"), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Securities. By the terms of the Indenture, the Series Securities are issuable in series that may vary as to amount, date of maturity, rate of interest and in other respects as provided in the Indenture. This series of Securities is limited in aggregate principal amount as specified in said Third Supplemental Indenture.

    The Debentures are not entitled to the benefit of any sinking fund.

    In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of all of the Debentures may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

    The Indenture contains provisions permitting the Company and the Trustee, with the consent of the Holders of not less than a majority in aggregate principal amount of the Series Securities of each series affected at the time outstanding, as defined in the Indenture, to execute supplemental indentures for the purpose of, among other things, adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or of modifying in any manner the rights of the Holders of the Series Securities; provided, however, that, among other things, no such supplemental indenture shall (i) reduce the principal amount thereof, or reduce the rate or extend the time of payment of interest thereon without the consent of the Holder of each Series Security so affected, or (ii) reduce the aforesaid percentage of Series Securities, the Holders of which are required to consent to any such supplemental indenture, without the consent of the Holders of each Series Security then outstanding and affected thereby. The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of the Series Securities of any series at the time outstanding affected thereby, on behalf of all of the Holders of the Series Securities of such series, to waive a default or Event of Default with respect to such series, and its consequences, except a default or Event of Default in the payment of the principal of or interest on any of the Series Securities of such series or a default in respect of a provision that under Article Nine of the Indenture cannot be amended without the consent of each holder affected thereby. Any such consent or waiver by the registered Holder of this Debenture (unless revoked as provided in the Indenture) shall be conclusive and binding upon such Holder and upon all future Holders and owners of this Debenture and of any Debenture issued in exchange for or in place hereof (whether by registration of transfer or otherwise), irrespective of whether or not any notation of such consent or waiver is made upon this Debenture.

    No reference herein to the Indenture and no provision of this Debenture or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Debenture at the time and place and at the rate and in the money herein prescribed.

    As provided in the Indenture and subject to certain limitations therein set forth, this Debenture is transferable by the registered Holder hereof on the Security Register of the Company, upon surrender

15

of this Debenture for registration of transfer at the office or agency of the Trustee in The City of New York and State of New York accompanied by a written instrument or instruments of transfer in form satisfactory to the Company or the Trustee duly executed by the registered Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Debentures of authorized denominations and for the same aggregate principal amount and series will be issued to the designated transferee or transferees. No service charge will be made for any such transfer, but the Company may require payment of a sum sufficient to cover any tax, assessment or other governmental charge payable in relation thereto.

    Prior to due presentment for registration of transfer of this Debenture, the Company, the Trustee, any paying agent and the Security Registrar may deem and treat the registered holder hereof as the absolute owner hereof (whether or not this Debenture shall be overdue and notwithstanding any notice of ownership or writing hereon made by anyone other than the Security Registrar) for the purpose of receiving payment of or on account of the principal hereof and interest due hereon and for all other purposes, and neither the Company nor the Trustee nor any paying agent nor any Security Registrar shall be affected by any notice to the contrary.

    No recourse shall be had for the payment of the principal of or the interest on this Debenture, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture, against any incorporator, shareholder, officer or director, past, present or future, as such, of the Company or of any predecessor or successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issuance hereof, expressly waived and released.

    The Indenture imposes certain limitations on the ability of the Company to, among other things, merge or consolidate with any other Person or sell, assign, transfer, lease or convey all or substantially all of its properties and assets. All such covenants and limitations are subject to a number of important qualifications and exceptions. The Company must report periodically to the Series Trustee on compliance with the covenants in the Indenture.

    The Debentures of this series are issuable only in registered form without coupons, in denominations of $50 and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, Debentures of this series so issued are exchangeable for a like aggregate principal amount of Debentures of this series of a different authorized denomination, as requested by the Holder surrendering the same.

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

    This Debenture shall be governed by and construed in accordance with the laws of the State of New York, without regard to its principles of conflicts of laws.

    The Certificates shall be issuable only in registered form and only in denominations of a single Unit and any integral multiple thereof.

    Section 3.2.  Rights and Obligations Evidenced by the Certificates.  Each Normal Units Certificate shall evidence the number of Normal Units specified therein, with each such Normal Unit representing the ownership by the Holder thereof of a beneficial interest in a Preferred Security or the appropriate Treasury Consideration, as the case may be, subject to the Pledge of such Preferred Security or such Treasury Consideration, as the case may be, by such Holder pursuant to the Pledge Agreement, and the rights and obligations of the Holder thereof and the Company under one Purchase Contract. The Agent as attorney-in-fact for, and on behalf of, the Holder of each Normal Unit shall pledge, pursuant to the Pledge Agreement, the Preferred Security or the appropriate Treasury Consideration, as the case may be, forming a part of such Normal Unit, to the Collateral Agent and grant to the Collateral Agent

13

a security interest in the right, title, and interest of such Holder in such Preferred Security or such Treasury Consideration, as the case may be, for the benefit of the Company, to secure the obligation of the Holder under each Purchase Contract to purchase the Common Stock of the Company. Prior to the purchase of shares of Common Stock under each Purchase Contract, such Purchase Contracts shall not entitle the Holders of Normal Units Certificates to any of the rights of a holder of shares of Common Stock, including, without limitation, the right to vote or receive any dividends or other payments or to consent or to receive notice as stockholders in respect of the meetings of stockholders or for the election of directors of the Company or for any other matter, or any other rights whatsoever as stockholders of the Company.

    Each Stripped Units Certificate shall evidence the number of Stripped Units specified therein, with each such Stripped Unit representing the ownership by the Holder thereof of a ¹/20 undivided beneficial interest in a Treasury Security, subject to the Pledge of such interest in such Treasury Security by such Holder pursuant to the Pledge Agreement, and the rights and obligations of the Holder thereof and the Company under one Purchase Contract. Prior to the purchase of shares of Common Stock under each Purchase Contract, such Purchase Contracts shall not entitle the Holders of Stripped Units Certificates to any of the rights of a holder of shares of Common Stock, including, without limitation, the right to vote or receive any dividends or other payments or to consent or to receive notice as stockholders in respect of the meetings of stockholders or for the election of directors of the Company or for any other matter, or any other rights whatsoever as stockholders of the Company.

    Section 3.3.  Execution, Authentication, Delivery and Dating.  Subject to the provisions of Sections 3.13 and 3.14, upon the execution and delivery of this Agreement, and at any time and from time to time thereafter, the Company may deliver Certificates executed by the Company to the Agent for authentication, execution on behalf of the Holders and delivery, together with its Issuer Order for authentication of such Certificates, and the Agent in accordance with such Issuer Order shall authenticate, execute on behalf of the Holders and deliver such Certificates.

    The Certificates shall be executed on behalf of the Company by the Chairman of the Board, the President, any Vice President, the Controller, the Treasurer or the Corporate Secretary (or other officer performing similar functions) of the Company and delivered to the Agent. The signature of any of these officers on the Certificates may be manual or facsimile.

    Certificates bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Certificates or did not hold such offices at the date of such Certificates.

    No Purchase Contract evidenced by a Certificate shall be valid until such Certificate has been executed on behalf of the Holder by the manual signature of an authorized signatory of the Agent, as such Holder's attorney-in-fact. Such signature by an authorized signatory of the Agent shall be conclusive evidence that the Holder of such Certificate has entered into the Purchase Contracts evidenced by such Certificate.

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

    Section 3.4.  Temporary Certificates.  Pending the preparation of definitive Certificates, the Company shall execute and deliver to the Agent, and the Agent shall authenticate, execute on behalf of the Holders, and deliver, in lieu of such definitive Certificates, temporary Certificates which are in

14

substantially the forms set forth in Exhibit A and Exhibit B hereto, as the case may be, with such letters, numbers or other marks of identification or designation and such legends or endorsements printed, lithographed or engraved thereon as may be required by the rules of any securities exchange on which the Normal Units or Stripped Units, as the case may be, are listed, or as may, consistently herewith, be determined by the officers of the Company executing such Certificates, as evidenced by their execution of the Certificates.

    If temporary Certificates are issued, the Company will cause definitive Certificates to be prepared without unreasonable delay. After the preparation of definitive Certificates, the temporary Certificates shall be exchangeable for definitive Certificates upon surrender of the temporary Certificates at the Corporate Trust Office, at the expense of the Company and without charge to the Holder. Upon surrender for cancellation of any one or more temporary Certificates, the Company shall execute and deliver to the Agent, and the Agent shall authenticate, execute on behalf of the Holder, and deliver in exchange therefor, one or more definitive Certificates of like tenor and denominations and evidencing a like number of Normal Units or Stripped Units, as the case may be, as the temporary Certificate or Certificates so surrendered. Until so exchanged, the temporary Certificates shall in all respects evidence the same benefits and the same obligations with respect to the Normal Units or Stripped Units, as the case may be, evidenced thereby as definitive Certificates.

    Section 3.5.  Registration; Registration of Transfer and Exchange.  The Agent shall keep at the Corporate Trust Office a register (the "Normal Units Register") in which, subject to such reasonable regulations as it may prescribe, the Agent shall provide for the registration of Normal Units Certificates and of transfers of Normal Units Certificates (the Agent, in such capacity, the "Normal Units Registrar") and a register (the "Stripped Units Register") in which, subject to such reasonable regulations as it may prescribe, the Agent shall provide for the registration of the Stripped Units Certificates and transfers of Stripped Units Certificates (the Agent, in such capacity, the "Stripped Units Registrar").

    Upon surrender for registration of transfer of any Certificate at the Corporate Trust Office, the Company shall execute and deliver to the Agent, and the Agent shall authenticate, execute on behalf of the designated transferee or transferees, and deliver, in the name of the designated transferee or transferees, one or more new Certificates of like tenor and denominations, and evidencing a like number of Normal Units or Stripped Units, as the case may be.

    At the option of the Holder, Certificates may be exchanged for other Certificates, of like tenor and denominations and evidencing a like number of Normal Units or Stripped Units, as the case may be, upon surrender of the Certificates to be exchanged at the Corporate Trust Office. Whenever any Certificates are so surrendered for exchange, the Company shall execute and deliver to the Agent, and the Agent shall authenticate, execute on behalf of the Holder, and deliver the Certificates which the Holder making the exchange is entitled to receive.

    All Certificates issued upon any registration of transfer or exchange of a Certificate shall evidence the ownership of the same number of Normal Units or Stripped Units, as the case may be, and be entitled to the same benefits and subject to the same obligations, under this Agreement as the Normal Units or Stripped Units, as the case may be, evidenced by the Certificate surrendered upon such registration of transfer or exchange.

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

    No service charge shall be made for any registration of transfer or exchange of a Certificate, but the Company and the Agent may require payment from the Holder of a sum sufficient to cover any tax

15

or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Certificates, other than any exchanges pursuant to Sections 3.6, 3.9 and 8.5 not involving any transfer.

    Notwithstanding the foregoing, the Company shall not be obligated to execute and deliver to the Agent, and the Agent shall not be obligated to authenticate, execute on behalf of the Holder and deliver, any Certificate presented or surrendered for registration of transfer or for exchange on or after the Business Day immediately preceding the earlier of the Stock Purchase Date or the Termination Date. In lieu of delivery of a new Certificate, upon satisfaction of the applicable conditions specified above in this Section and receipt of appropriate registration or transfer instructions from such Holder, the Agent shall (i) if the Stock Purchase Date has occurred, deliver the shares of Common Stock issuable in respect of the Purchase Contracts forming a part of the Units evidenced by such Certificate, (ii) in the case of Normal Units, if a Termination Event shall have occurred prior to the Stock Purchase Date, transfer the Preferred Securities or the appropriate Treasury Consideration, as applicable, relating to such Normal Units, or (iii) in the case of Stripped Units, if a Termination Event shall have occurred prior to the Stock Purchase Date, transfer the Treasury Securities relating to such Stripped Units, in each case subject to the applicable conditions and in accordance with the applicable provisions of Article Five.

    Section 3.6.  Book-Entry Interests.  The Certificates, on original issuance, will be issued in the form of one or more fully registered Global Certificates, to be delivered to the Depositary by, or on behalf of, the Company. Each such Global Certificate shall initially be registered on the books and records of the Company in the name of Cede & Co., the nominee of the Depositary, and no Beneficial Owner will receive a definitive Certificate representing such Beneficial Owner's interest in such Global Certificate, except as provided in Section 3.9. The Agent shall enter into an agreement with the Depositary if so requested by the Company. Unless and until definitive, fully registered Certificates have been issued to Beneficial Owners pursuant to Section 3.9:

    (a) the provisions of this Section 3.6 shall be in full force and effect;

    (b) the Company shall be entitled to deal with the Clearing Agency for all purposes of this Agreement (including receiving approvals, votes or consents hereunder) as the Holder of the Units and the sole holder of the Global Certificate(s) and shall have no obligation to the Beneficial Owners;

    (c) to the extent that the provisions of this Section 3.6 conflict with any other provisions of this Agreement, the provisions of this Section 3.6 shall control; and

    (d) the rights of the Beneficial Owners shall be exercised only through the Clearing Agency and shall be limited to those established by law and agreements between such Beneficial Owners and the Clearing Agency and/or the Clearing Agency Participants. The Clearing Agency will make book-entry transfers among Clearing Agency Participants.

    Section 3.7.  Notices to Holders.  Whenever a notice or other communication to the Holders is required to be given under this Agreement, the Company or the Company's agent shall give such notices and communications to the Holders and, with respect to any Units registered in the name of a Clearing Agency or the nominee of a Clearing Agency, the Company or the Company's agent shall, except as set forth herein, have no obligations to the Beneficial Owners.

16

    Section 3.8.  Appointment of Successor Clearing Agency.  If any Clearing Agency elects to discontinue its services as securities depositary with respect to the Units, the Company may, in its sole discretion, appoint a successor Clearing Agency with respect to the Units.

    Section 3.9.  Definitive Certificates.  If (i) a Clearing Agency elects to discontinue its services as securities depositary with respect to the Units and a successor Clearing Agency is not appointed within 90 days after such discontinuance pursuant to Section 3.8, (ii) the Company elects to terminate the book-entry system through the Clearing Agency with respect to the Units, or (iii) there shall have occurred and be continuing a default by the Company in respect of its obligations under one or more Purchase Contracts, then upon surrender of the Global Certificates representing the Book-Entry Interests with respect to the Units by the Clearing Agency, accompanied by registration instructions, the Company shall cause definitive Certificates to be delivered to Beneficial Owners in accordance with the instructions of the Clearing Agency. The Company shall not be liable for any delay in delivery of such instructions and may conclusively rely on and shall be protected in relying on, such instructions.

    Section 3.10.  Mutilated, Destroyed, Lost and Stolen Certificates.  If any mutilated Certificate is surrendered to the Agent, the Company shall execute and deliver to the Agent, and the Agent shall authenticate, execute on behalf of the Holder, and deliver in exchange therefor, a new Certificate at the cost of the Holder, evidencing the same number of Normal Units or Stripped Units, as the case may be, and bearing a Certificate number not contemporaneously outstanding.

    If there shall be delivered to the Company and the Agent (i) evidence to their satisfaction of the destruction, loss or theft of any Certificate, and (ii) such security or indemnity at the cost of the Holder as may be required by them to hold each of them and any agent of any of them harmless, then, in the absence of notice to the Company or the Agent that such Certificate has been acquired by a bona fide purchaser, the Company shall execute and deliver to the Agent, and the Agent shall authenticate, execute on behalf of the Holder, and deliver to the Holder, in lieu of any such destroyed, lost or stolen Certificate, a new Certificate, evidencing the same number of Normal Units or Stripped Units, as the case may be, and bearing a Certificate number not contemporaneously outstanding.

    Notwithstanding the foregoing, the Company shall not be obligated to execute and deliver to the Agent, and the Agent shall not be obligated to authenticate, execute on behalf of the Holder, and deliver to the Holder, a Certificate on or after the Business Day immediately preceding the earlier of the Stock Purchase Date or the Termination Date. In lieu of delivery of a new Certificate, upon satisfaction of the applicable conditions specified above in this Section and receipt of appropriate registration or transfer instructions from such Holder, the Agent shall (i) if the Stock Purchase Date has occurred, deliver the shares of Common Stock issuable in respect of the Purchase Contracts forming a part of the Units evidenced by such Certificate, or (ii) if a Termination Event shall have occurred prior to the Stock Purchase Date, transfer the Preferred Securities, the appropriate Treasury Consideration or the Treasury Securities, as the case may be, evidenced thereby, in each case subject to the applicable conditions and in accordance with the applicable provisions of Article Five.

    Upon the issuance of any new Certificate under this Section, the Company and the Agent may require the payment by the Holder 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 Agent) connected therewith.

    Every new Certificate issued pursuant to this Section in lieu of any destroyed, lost or stolen Certificate shall constitute an original additional contractual obligation of the Company and of the Holder in respect of the Unit evidenced thereby, whether or not the destroyed, lost or stolen Certificate (and the Units evidenced thereby) shall be at any time enforceable by anyone, and shall be entitled to all the benefits and be subject to all the obligations of this Agreement equally and proportionately with any and all other Certificates delivered hereunder.

17

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

    Section 3.11.  Persons Deemed Owners.  Prior to due presentment of a Certificate for registration of transfer, the Company and the Agent, and any agent of the Company or the Agent, may treat the Person in whose name such Certificate is registered as the owner of the Units evidenced thereby, for the purpose of receiving distributions on the Preferred Securities, performance of the Purchase Contracts and for all other purposes whatsoever, whether or not any such distributions constituting a part of the Units evidenced thereby shall be overdue and notwithstanding any notice to the contrary, and neither the Company nor the Agent, nor any agent of the Company or the Agent, shall be affected by notice to the contrary.

    Notwithstanding the foregoing, with respect to any Global Certificate, nothing herein shall prevent the Company, the Agent or any agent of the Company or the Agent, from giving effect to any written certification, proxy or other authorization furnished by any Clearing Agency (or its nominee), as a Holder, with respect to such Global Certificate or impair, as between such Clearing Agency and owners of beneficial interests in such Global Certificate, the operation of customary practices governing the exercise of rights of such Clearing Agency (or its nominee) as Holder of such Global Certificate.

    Section 3.12.  Cancellation.  All Certificates surrendered (i) for delivery of shares of Common Stock on or after any Settlement Date; (ii) upon the transfer of Preferred Securities, the appropriate Treasury Consideration or Treasury Securities, as the case may be, after the occurrence of a Termination Event; (iii) upon the registration of a transfer or exchange of a Unit shall, if surrendered to any Person other than the Agent, be delivered to the Agent and, if not already cancelled, shall be promptly cancelled by it. The Company may at any time deliver to the Agent for cancellation any Certificates previously authenticated, executed and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Certificates so delivered shall, upon Issuer Order, be promptly cancelled by the Agent. No Certificates shall be authenticated, executed on behalf of the Holder and delivered in lieu of or in exchange for any Certificates cancelled as provided in this Section, except as expressly permitted by this Agreement. All cancelled Certificates held by the Agent shall be disposed of by the Agent in accordance with its customary procedures.

    If the Company or any Affiliate of the Company shall acquire any Certificate, such acquisition shall not operate as a cancellation of such Certificate unless and until such Certificate is delivered to the Agent cancelled or for cancellation.

    Section 3.13.  Establishment of Stripped Units.  A Holder may separate the Pledged Preferred Securities or Treasury Consideration, as applicable, from the related Purchase Contracts in respect of the Normal Units held by such Holder by substituting for such Pledged Preferred Securities or Pledged Treasury Consideration, as the case may be, Treasury Securities as set forth below (a "Collateral Substitution"), at any time from and after the date of this Agreement and on or prior to the second Business Day immediately preceding the Stock Purchase Date. To effect a Collateral Substitution, a Holder should (a) deposit with the Collateral Agent Treasury Securities having an aggregate principal amount equal to the aggregate Stated Amount of such Normal Units, and (b) transfer the related Normal Units to the Agent accompanied by a notice to the Agent, substantially in the form of Exhibit D hereto, stating that the Holder has transferred the relevant amount of Treasury Securities to the Collateral Agent and requesting that the Agent instruct the Collateral Agent to release the Preferred Securities or Pledged Treasury Consideration, as the case may be, underlying such Normal Units, whereupon the Agent shall promptly give such instruction to the Collateral Agent, substantially in the form of Exhibit C hereto. Notwithstanding the foregoing, a Holder may not separate the Pledged Preferred Securities or Pledged Treasury Consideration, as the case may be, from the related Purchase Contracts in respect of the Normal Units held by such Holder after the fifth Business Day before the

18

Remarketing Date or any Subsequent Remarketing Date. Upon receipt of the Treasury Securities described in clause (a) above and the instruction described in clause (b) above, in accordance with the terms of the Pledge Agreement, the Collateral Agent will release to the Agent, on behalf of the Holder, such Pledged Preferred Securities or Pledged Treasury Consideration, as the case may be, from the Pledge, free and clear of the Company's security interest therein, and upon receipt thereof the Agent shall promptly:

     (i) cancel the related Normal Units;

    (ii) transfer the Pledged Preferred Securities or Pledged Treasury Consideration, as the case may be, to the Holder; and

    (iii) authenticate, execute on behalf of such Holder and deliver a Stripped Units Certificate executed by the Company in accordance with Section 3.3 evidencing the same number of Purchase Contracts as were evidenced by the cancelled Normal Units.

    Holders who elect to separate the Pledged Preferred Securities or Pledged Treasury Consideration, as the case may be, from the related Purchase Contract and to substitute Treasury Securities for such Pledged Preferred Securities or Pledged Treasury Consideration, as the case may be, shall be responsible for any fees or expenses payable to the Collateral Agent for its services as Collateral Agent in respect of the substitution, and the Company shall not be responsible for any such fees or expenses.

    Holders may make Collateral Substitutions (i) if Treasury Securities are being substituted for Pledged Preferred Securities, only in integral multiples of 20 Normal Units, or (ii) if the Collateral Substitutions occur after the Remarketing Date or any Subsequent Remarketing Date, as the case may be, only in integral multiples of Normal Units such that the Treasury Securities to be deposited and the Treasury Consideration to be released are in integral multiples of $1,000.

    In the event a Holder making a Collateral Substitution pursuant to this Section 3.13 fails to effect a book-entry transfer of the Normal Units or fails to deliver a Normal Units Certificate to the Agent after depositing Treasury Securities with the Collateral Agent, the Pledged Preferred Securities or Pledged Treasury Consideration, as the case may be, constituting a part of such Normal Units, and any distributions on such Pledged Preferred Securities or Pledged Treasury Consideration, as the case may be, shall be held in the name of the Agent or its nominee in trust for the benefit of such Holder, until such Normal Units are so transferred or the Normal Units Certificate is so delivered, as the case may be, or, with respect to a Normal Units Certificate, such Holder provides evidence satisfactory to the Company and the Agent that such Normal Units Certificate has been destroyed, lost or stolen, together with any indemnity that may be required by the Agent and the Company.

    Except as described in this Section 3.13, for so long as the Purchase Contract underlying a Normal Unit remains in effect, such Normal Unit shall not be separable into its constituent parts, and the rights and obligations of the Holder of such Normal Unit in respect of the Preferred Security or the appropriate Treasury Consideration, as the case may be, and the Purchase Contract comprising such Normal Unit may be acquired, and may be transferred and exchanged, only as a Normal Unit.

    Section 3.14.  Reestablishment of Normal Units.  A Holder of Stripped Units may reestablish Normal Units at any time (i) on or prior to the fifth Business Day immediately preceding the Stock Purchase Date, if a Tax Event Redemption has not occurred, and (ii) on or prior to the second Business Day immediately preceding the Stock Purchase Date, if a Tax Event Redemption has occurred, in each case, by (a) depositing with the Collateral Agent the Preferred Securities or the appropriate Treasury Consideration (and identified by reference to the Treasury Consideration then comprising Normal Units), as the case may be, then comprising such number of Normal Units as is equal to such Stripped Units and (b) transferring such Stripped Units to the Agent accompanied by a notice to the Agent, substantially in the form of Exhibit D hereto, stating that the Holder has transferred the relevant amount of Preferred Securities or the appropriate Treasury Consideration, as

19

the case may be, to the Collateral Agent and requesting that the Agent instruct the Collateral Agent to release the Pledged Treasury Securities underlying such Stripped Unit, whereupon the Agent shall promptly give such instruction to the Collateral Agent, substantially in the form of Exhibit C hereto. Notwithstanding the foregoing, a Holder may not reestablish Normal Units during the period beginning on the fourth Business Day prior to the Remarketing Date or any Subsequent Remarketing Date, as the case may be, and ending at 5:00 p.m., New York City time, on the third Business Day following such dates. Upon receipt of the Preferred Securities or the appropriate Treasury Consideration, as the case may be, described in clause (a) above and the instruction described in clause (b) above, in accordance with the terms of the Pledge Agreement, the Collateral Agent will release to the Agent, on behalf of the Holder, such Pledged Treasury Securities from the Pledge, free and clear of the Company's security interest therein, and upon receipt thereof the Agent shall promptly:

     (i) cancel the related Stripped Units;

    (ii) transfer the Pledged Treasury Securities to the Holder; and

    (iii) authenticate, execute on behalf of such Holder and deliver a Normal Units Certificate executed by the Company in accordance with Section 3.3 evidencing the same number of Purchase Contracts as were evidenced by the cancelled Stripped Units.

    Holders of Stripped Units may reestablish Normal Units (i) only in integral multiples of 20 Stripped Units for 20 Normal Units or (ii) if the reestablishment occurs after a Tax Event Redemption has occurred or after the Remarketing Date or any Subsequent Remarketing Date, only in integral multiples of Stripped Units such that the Treasury Consideration to be deposited and the Treasury Securities to be released are in integral multiples of $1,000.

    Except as provided in this Section 3.14, for so long as the Purchase Contract underlying a Stripped Unit remains in effect, such Stripped Unit shall not be separable into its constituent parts, and the rights and obligations of the Holder of such Stripped Unit in respect of the Treasury Security and Purchase Contract comprising such Stripped Unit may be acquired, and may be transferred and exchanged, only as a Stripped Unit.

    Section 3.15.  Transfer of Collateral upon Occurrence of Termination Event.  Upon the occurrence of a Termination Event and the transfer to the Agent of the Preferred Securities, the appropriate Treasury Consideration or the Treasury Securities, as the case may be, underlying the Normal Units and the Stripped Units pursuant to the terms of the Pledge Agreement, the Agent shall request transfer instructions with respect to the Preferred Securities, the appropriate Treasury Consideration or the Treasury Securities, as the case may be, from each Holder by written request mailed to such Holder at its address as it appears in the Normal Units Register or the Stripped Units Register, as the case may be. Upon book-entry transfer of the Normal Units or Stripped Units or delivery of a Normal Units Certificate or Stripped Units Certificate to the Agent with such transfer instructions, the Agent shall transfer the Preferred Securities, the appropriate Treasury Consideration or the Treasury Securities, as the case may be, underlying such Normal Units or Stripped Units, as the case may be, to such Holder by book-entry transfer, or other appropriate procedures, in accordance with such instructions. In the event a Holder of Normal Units or Stripped Units fails to effect such transfer or delivery, the Preferred Securities, the appropriate Treasury Consideration or the Treasury Securities, as the case may be, underlying such Normal Units or Stripped Units, as the case may be, and any distributions thereon, shall be held in the name of the Agent or its nominee in trust for the benefit of such Holder, until such Normal Units or Stripped Units are transferred or the Normal Units Certificate or Stripped Units Certificate is surrendered or such Holder provides satisfactory evidence that such Normal Units Certificate or Stripped Units Certificate has been destroyed, lost or stolen, together with any indemnity that may be required by the Agent and the Company.

20

    Section 3.16.  No Consent to Assumption.  Each Holder of a Unit, by acceptance thereof, shall be deemed expressly to have withheld any consent to the assumption under Section 365 of the Bankruptcy Code or otherwise, of the Purchase Contract by the Company, any receiver, liquidator or person or entity performing similar functions or its trustee in the event that the Company becomes the debtor under the Bankruptcy Code or subject to other similar state or federal law providing for reorganization or liquidation.

    Section 3.17  CUSIP Numbers.  The Trust in issuing the Preferred Securities may use "CUSIP" numbers (if then generally in use), and, if so, the Property Trustee shall use "CUSIP" numbers in notices of redemption as a convenience to holders of the Preferred Securities; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Preferred Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Preferred Securities, and any such redemption shall not be affected by any defect in or omission of such numbers.

ARTICLE IV
THE PREFERRED SECURITIES

    Section 4.1.  Payment of Distributions; Rights to Distributions Preserved; Notice.  A distribution on any Preferred Security or a payment on any Treasury Consideration, as the case may be, which is paid on any Payment Date shall, subject to receipt thereof by the Agent from the Collateral Agent as provided by the terms of the Pledge Agreement, be paid to the Person in whose name the Normal Units Certificate (or one or more Predecessor Normal Units Certificates) of which such Preferred Security or the appropriate Treasury Consideration, as the case may be, is a part is registered at the close of business on the Record Date for such Payment Date.

    Each Normal Units Certificate evidencing Preferred Securities delivered under this Agreement upon registration of transfer of or in exchange for or in lieu of any other Normal Units Certificate shall carry the rights to distributions accumulated and unpaid, and to accumulate distributions, which were carried by the Preferred Securities underlying such other Normal Units Certificate.

    In the case of any Normal Unit with respect to which Early Settlement of the underlying Purchase Contract is effected on an Early Settlement Date, or with respect to which Merger Early Settlement of the underlying Purchase Contract is effected on a Merger Early Settlement Date, or with respect to which a Collateral Substitution is effected, in each case on a date that is after any Record Date and on or prior to the next succeeding Payment Date, distributions on the Preferred Security or payments on the appropriate Treasury Consideration, as the case may be, underlying such Normal Unit otherwise payable on such Payment Date shall be payable on such Payment Date notwithstanding such Early Settlement, Merger Early Settlement or Collateral Substitution, as the case may be, and such distributions shall, subject to receipt thereof by the Agent, be payable to the Person in whose name the Normal Units Certificate (or one or more Predecessor Normal Unit Certificates) was registered at the close of business on the Record Date. Except as otherwise expressly provided in the immediately preceding sentence, in the case of any Normal Unit with respect to which Early Settlement or Merger Early Settlement of the underlying Purchase Contract is effected, or with respect to which a Collateral Substitution has been effected, distributions on the related Preferred Securities or payments on the appropriate Treasury Consideration, as the case may be, that would otherwise be payable after the applicable Settlement Date or after such Collateral Substitution, as the case may be, shall not be payable hereunder to the Holder of such Normal Unit; provided, that to the extent that such Holder continues to hold the Separate Preferred Securities that formerly comprised a part of such Holder's Normal Units, such Holder shall be entitled to receive the distributions on such Separate Preferred Securities.

21

    Section 4.2.  Notice and Voting.  Under the terms of the Pledge Agreement, the Agent will be entitled to exercise the voting and any other consensual rights pertaining to the Pledged Preferred Securities but only to the extent instructed by the Holders as described below. Upon receipt of notice of any meeting at which holders of Preferred Securities are entitled to vote or upon any solicitation of consents, waivers or proxies of holders of Preferred Securities, the Agent shall, as soon as practicable thereafter, mail to the Holders of Normal Units a notice (a) containing such information as is contained in the notice or solicitation, (b) stating that each Holder on the record date set by the Agent therefor (which, to the extent possible, shall be the same date as the record date for determining the holders of Preferred Securities entitled to vote) shall be entitled to instruct the Agent as to the exercise of the voting rights pertaining to the Pledged Preferred Securities underlying their Normal Units and (c) stating the manner in which such instructions may be given. Upon the written request of the Holders of Normal Units on such record date, the Agent shall endeavor insofar as practicable to vote or cause to be voted, in accordance with the instructions set forth in such requests, the maximum number of Pledged Preferred Securities as to which any particular voting instructions are received. In the absence of specific instructions from the Holder of a Normal Unit, the Agent shall abstain from voting the Pledged Preferred Security underlying such Normal Unit. The Company hereby agrees, if applicable, to solicit Holders of Normal Units to timely instruct the Agent in order to enable the Agent to vote such Pledged Preferred Securities and the Trust shall covenant to such effect in the Declaration.

    Section 4.3.  Distribution of Senior Debentures.  Upon a voluntary or involuntary dissolution of the Trust in accordance with the Declaration, the Liquidation Distribution (as defined in the Declaration) shall be delivered to the Collateral Agent in exchange for the Pledged Preferred Securities. Thereafter, the applicable part of the Liquidation Distribution (as defined in the Declaration) will be substituted for the Pledged Preferred Securities, and will be held by the Collateral Agent in accordance with the terms of the Pledge Agreement to secure the obligations of each Holder of Normal Units to purchase the Common Stock of the Company under the Purchase Contracts constituting a part of such Normal Units. The remaining portion of the Liquidation Distribution shall be distributed to the Holders of Separate Preferred Securities (as defined in the Pledge Agreement). Following a voluntary or involuntary dissolution of the Trust, the Holders and the Collateral Agent shall have such security interests, rights and obligations with respect to the Liquidation Distribution as the Holders and the Collateral Agent had in respect of the Pledged Preferred Securities as provided in Articles II, III, IV, V and VI of the Pledge Agreement, and, unless the context otherwise requires, any reference herein to the Preferred Securities or Pledged Preferred Securities shall be deemed to be a reference to such Senior Debentures. The Company may cause to be made in any Normal Units Certificates thereafter to be issued such change in phraseology and form (but not in substance) as may be appropriate to reflect the liquidation of the Trust and the substitution of Senior Debentures for Preferred Securities as Collateral.

    Section 4.4.  Tax Event Redemption.  Upon the occurrence of a Tax Event Redemption prior to the Stock Purchase Date or any Remarketing Date, the Redemption Amount payable to the Agent on behalf of the Holders of Normal Units on the Redemption Date with respect to the Preferred Securities shall be delivered by the Agent to the Collateral Agent in exchange for the Pledged Preferred Securities. Pursuant to the terms of the Pledge Agreement, the Collateral Agent will apply an amount equal to the Redemption Amount to purchase on behalf of the Holders of Normal Units, on a pro rata basis, the Redemption Treasury Portfolio and promptly remit the remaining portion of such Redemption Amount, if any, to the Agent for payment to the Holders of such Normal Units on a pro rata basis. The Redemption Treasury Portfolio will be substituted for the Pledged Preferred Securities, and will be held by the Collateral Agent in accordance with the terms of the Pledge Agreement to secure the obligation of each Holder of a Normal Unit to purchase the Common Stock of the Company under the Purchase Contract constituting a part of such Normal Unit. Following the occurrence of a Tax Event Redemption prior to the Stock Purchase Date or any Remarketing Date, the Holders of Normal Units and the Collateral Agent shall have such security interests, rights and

22

obligations with respect to the Redemption Treasury Portfolio as the Holder of Normal Units and the Collateral Agent had in respect of the Preferred Securities subject to the Pledge thereof as provided in Articles II, III, IV, V, and VI of the Pledge Agreement, and any reference herein to the Preferred Securities shall be deemed to be reference to such Redemption Treasury Portfolio. The Company may cause to be made in any Normal Unit Certificates thereafter to be issued such change in phraseology and form (but not in substance) as may be appropriate to reflect the liquidation of the Trust and the substitution of the Redemption Treasury Portfolio for Preferred Securities as collateral.

    Section 4.5  Consent to Treatment for Tax Purposes.  Each Holder of a Unit, by its acceptance thereof, covenants and agrees to treat itself as the owner, for United States federal, state and local income and franchise tax purposes, of (i) the related Preferred Securities or the appropriate Treasury Consideration, in the case of the Normal Units, or (ii) the Treasury Securities, in the case of the Stripped Units. Each Holder of Normal Units, by its acceptance thereof, further covenants and agrees to treat the Preferred Securities as indebtedness of the Company for United States federal, state and local income and franchise tax purposes.

ARTICLE V
THE PURCHASE CONTRACTS; THE REMARKETING

    Section 5.1.  Purchase of Shares of Common Stock.  Each Purchase Contract shall, unless an Early Settlement has occurred in accordance with Section 5.7, or a Merger Early Settlement has occurred in accordance with Section 5.8, obligate the Holder of the related Unit to purchase, and the Company to sell, on the Stock Purchase Date at a price equal to $50 (the "Purchase Price"), a number of newly issued shares of Common Stock equal to the Settlement Rate unless, on or prior to the Stock Purchase Date, there shall have occurred a Termination Event with respect to the Unit of which such Purchase Contract is a part. The "Settlement Rate" is equal to (a) if the Average Trading Price (as defined below) is equal to or greater than $38.88 (the "Threshold Appreciation Price"), 1.2860 shares of Common Stock per Purchase Contract, (b) if the Average Trading Price is less than the Threshold Appreciation Price, but is greater than $31.87, the number of shares of Common Stock per Purchase Contract equal to the Stated Amount of the related Unit divided by the Average Trading Price and (c) if the Average Trading Price is less than $31.87, 1.5689 shares of Common Stock per Purchase Contract, in each case subject to adjustment as provided in Section 5.4 (and in each case rounded upward or downward to the nearest 1/10,000th of a share). As provided in Section 5.10, no fractional shares of Common Stock will be issued upon settlement of Purchase Contracts.

    The "Average Trading Price" means the average of the Closing Price per share of Common Stock on each of the 20 consecutive Trading Days ending on the third Trading Day immediately preceding the Stock Purchase Date. The "Closing Price" of the Common Stock on any date of determination means the closing sale price (or, if no closing price is reported, the last reported sale price) of the Common Stock on the New York Stock Exchange (the "NYSE") on such date or, if the Common Stock is not listed for trading on the NYSE on any such date, as reported in the composite transactions for the principal United States securities exchange on which the Common Stock is so listed, or if the Common Stock is not so listed on a United States national or regional securities exchange, as reported by The Nasdaq Stock Market, or, if the Common Stock is not so reported, the last quoted bid price for the Common Stock in the over-the-counter market as reported by the National Quotation Bureau or similar organization, or, if such bid price is not available, the market value of the Common Stock on such date as determined by a nationally recognized independent investment banking firm retained for this purpose by the Company.

    Each Holder of a Unit, by its acceptance thereof, irrevocably authorizes the Agent to enter into and perform the related Purchase Contract on its behalf as its attorney-in-fact (including the execution of Certificates on behalf of such Holder), agrees to be bound by the terms and provisions thereof,

23

covenants and agrees to perform its obligations under such Purchase Contracts, and consents to the provisions hereof, irrevocably authorizes the Agent as its attorney-in-fact to enter into and perform the Pledge Agreement on its behalf as its attorney-in-fact, and consents to and agrees to be bound by the Pledge of the Preferred Securities, the appropriate Treasury Consideration or the Treasury Securities pursuant to the Pledge Agreement; provided that upon a Termination Event, the rights of the Holder of such Unit under the Purchase Contract may be enforced without regard to any other rights or obligations. Each Holder of a Unit, by its acceptance thereof, further covenants and agrees, that, to the extent and in the manner provided in Section 5.2 and the Pledge Agreement, but subject to the terms thereof, payments in respect of the Preferred Securities, the appropriate Treasury Consideration or the Treasury Securities to be paid upon settlement of such Holder's obligations to purchase Common Stock under the Purchase Contract, shall be paid on the Stock Purchase Date by the Collateral Agent to the Company in satisfaction of such Holder's obligations under such Purchase Contract.

    Upon registration of transfer of a Certificate, the transferee shall be bound (without the necessity of any other action on the part of such transferee) under the terms of this Agreement, the Purchase Contracts underlying such Certificate and the Pledge Agreement, and the transferor shall be released from the obligations under this Agreement, the Purchase Contracts underlying the Certificates so transferred and the Pledge Agreement. The Company covenants and agrees, and each Holder of a Certificate, by its acceptance thereof, likewise covenants and agrees, to be bound by the provisions of this paragraph.

    Section 5.2.  Payment of Purchase Price; Remarketing.  (a)   Unless a Tax Event Redemption, Termination Event, Early Settlement or Merger Early Settlement has occurred, the settlement of the Purchase Contract underlying a Unit will be made in accordance with this Section 5.2.

    (b)(i)The Company shall engage a nationally recognized investment bank (the "Remarketing Agent") pursuant to the Remarketing Agreement (substantially in the form attached hereto as Exhibit E, with such changes and modifications as the parties thereto may agree on) to sell the Preferred Securities of Holders of Normal Units, other than Holders that have elected not to participate in the remarketing pursuant to (iv) below, and holders of Separate Preferred Securities that have elected to participate in the remarketing pursuant to (iv) below and the procedures set forth in Section 4.5(c) of the Pledge Agreement. On the seventh Business Day prior to September 16, 2004, the Agent shall give Holders of Normal Units and holders of Separate Preferred Securities notice of remarketing in The Wall Street Journal, or if such publication ceases to publish notices of such type, or if it is otherwise impractical to publish such notice therein, in such other daily newspaper of general circulation in The City of New York, published in the English language, as the Company may reasonably determine, including the specific U.S. Treasury security or securities (including the CUSIP number and/or the principal terms of such Treasury security or securities), described in clause (iv) below, that must be delivered by Holders of Normal Units that elect not to participate in the remarketing pursuant to (iv) below, no later than 10:00 a.m., New York City time, on the Remarketing Date. The Agent shall notify the Remarketing Agent and the Collateral Agent of the aggregate number of Preferred Securities of Normal Unit Holders to be remarketed no later than 10:00 a.m., New York City time, on the Remarketing Date. On the Remarketing Date, no later than 10:00 a.m., New York City time, pursuant to the terms of the Pledge Agreement, the Custodial Agent will notify the Remarketing Agent of the aggregate number of Separate Preferred Securities to be remarketed. No later than 10:00 a.m., New York City time, on the Remarketing Date, the Collateral Agent and the Custodial Agent, pursuant to the terms of the Pledge Agreement, will deliver for remarketing to the Remarketing Agent all Preferred Securities to be remarketed. The Remarketing Agent will use the proceeds from a successful remarketing to purchase the appropriate U.S. Treasury securities (the "Agent-purchased Security Treasury Consideration") described in clauses (i)(1) and (ii)(1) of the definition of Remarketing Value in respect of the Preferred Securities of Holders of Normal Units

24

that were remarketed. On or prior to the third Business Day following the Remarketing Date, the Remarketing Agent shall deliver such Agent-purchased Treasury Consideration to the Agent, which shall thereupon deliver such Agent-purchased Treasury Consideration to the Collateral Agent. The Collateral Agent, for the benefit of the Company, will thereupon apply such Agent-purchased Treasury Consideration, in accordance with the Pledge Agreement, to secure such Holders' obligations under the Purchase Contracts. The Remarketing Agent will deduct as a remarketing fee an amount not exceeding 25 basis points (.25%) of the total proceeds from the remarketing. The Remarketing Agent will remit (1) the portion of the proceeds from the remarketing attributable to the Separate Preferred Securities to the holders of Separate Preferred Securities that were remarketed and (2) the remaining portion of the proceeds, less those proceeds used to purchase the Agent-purchased Treasury Consideration, to the Agent for the benefit of the Holders of the Normal Units that were remarketed, all determined on a pro rata basis, in each case, on or prior to the third Business Day following the Remarketing Date. Holders whose Preferred Securities are so remarketed will not otherwise be responsible for the payment of any Remarketing Fee in connection therewith.

    The "Remarketing Value" means the sum of (i) the value at the Remarketing Date or the Subsequent Remarketing Date, as the case may be, of U.S. Treasury securities that will pay, on or prior to the Quarterly Payment Date falling on the Stock Purchase Date, an amount of cash equal to the aggregate distributions that are scheduled to be payable on that Quarterly Payment Date, on (1) the Preferred Securities which are included in Normal Units and (2) no distribution payment on the Preferred Securities will then have been deferred and the distribution rate on the Preferred Securities is equal to the Coupon Rate, and (ii) the value at the Remarketing Date or the Subsequent Remarketing Date, as the case may be, of U.S. Treasury securities that will pay, on or prior to the Stock Purchase Date, an amount of cash equal to the Stated Amount of (1) such Preferred Securities that are included in Normal Units and (2) the Separate Preferred Securities, in each case, which are participating in the remarketing; provided that for purposes of clauses (i) and (ii), above, the Remarketing Value shall be calculated on the assumptions that the U.S. Treasury securities are highly liquid and mature on or within 35 days prior to the Stock Purchase Date, as determined in good faith by the Remarketing Agent in a manner intended to minimize the Remarketing Value, and the U.S. Treasury securities are valued based on the ask-side price of the Treasury securities at a time between 9:00 a.m. and 11:00 a.m., New York City time, selected by the Remarketing Agent, on the Remarketing Date or Subsequent Remarketing Date, as the case may be, as determined on a third-day settlement basis by a reasonable and customary means selected in good faith by the Remarketing Agent, plus accrued interest to that date.

25

    (ii) If, in spite of using its commercially reasonable best efforts, the Remarketing Agent cannot remarket the Preferred Securities included in the remarketing at a price equal to at least 100.5% of the Remarketing Value, the remarketing will be deemed to have failed (a "Failed Remarketing"). If the Remarketing Agent cannot remarket the Preferred Securities on the Remarketing Date, the Remarketing Agent shall use its commercially reasonable best efforts to attempt to remarket Preferred Securities on each of the two Business Days immediately following the Remarketing Date and, if necessary, on each of the three Business Days immediately preceding November 1, 2004, and if necessary, on each of the three Business Days immediately preceding the Stock Purchase Date in accordance with the remarketing procedures described in this Section 5.2(b) and the Pledge Agreement. Any Subsequent Remarketing shall be conducted in accordance with the dates and procedures set forth in this Section 5.2(b) and the Remarketing Agreement, provided that (i) the notice of any Subsequent Remarketing cannot be given until the Failed Remarketing notice (referred to below) has been published in respect of any immediately preceding Failed Remarketing and (ii) the settlement date in respect of any Subsequent Remarketing must fall no later than on the Business Day immediately preceding the Stock Purchase Date. If by the Stock Purchase Date the Remarketing Agent has failed to remarket the Preferred Securities at 100.5% of the Remarketing Value, in accordance with the terms of the Pledge Agreement, the Collateral Agent, for the benefit of the Company, may exercise its rights as a secured party with respect to such Preferred Securities, including those actions specified in (b)(iii) below; provided, that if upon a Failed Remarketing the Collateral Agent exercises such rights for the benefit of the Company with respect to such Preferred Securities, any accumulated and unpaid distributions on such Preferred Securities will become payable by the Company to the Agent for payment to the Holder of the Normal Units to which such Preferred Securities relates. Such payment will be made by the Company on or prior to 11:00 a.m., New York City time, on the Stock Purchase Date in lawful money of the United States by certified or cashiers' check or wire transfer in immediately available funds payable to or upon the order of the Agent. The Company will cause a notice of any Failed Remarketing to be published on the second Business Day following any Failed Remarketing in The Wall Street Journal, or if such publication ceases to publish notices of such type or if it is otherwise impractical to publish such notice therein, in such other daily newspaper of general circulation in The City of New York, published in the English language, as the Company may reasonably determine.

(iii)

With respect to any Preferred Securities which constitute part of Normal Units which are subject to a Failed Remarketing, the Collateral Agent for the benefit of the Company reserves all of its rights as a secured party with respect thereto and, subject to applicable law and paragraph (e) below, may, among other things, (x) retain such Trust Preferred Securities in full satisfaction of the Holders' obligations under the Purchase Contracts or (y) sell such Trust Preferred Securities in one or more public or private sales.



(iv)

A Holder of Normal Units may elect not to participate in the remarketing and retain the Preferred Securities underlying such Units by notifying the Agent of such election and delivering the specific U.S. Treasury security or securities (including the CUSIP number and/or the principal terms of such security or securities) identified by the Agent that constitute the U.S. Treasury securities described in clauses (i) and (ii) of the definition of Remarketing Value relating to the retained Preferred Securities (as if only such Preferred Securities were being remarketed) (the "Opt-out Treasury Consideration") to the Agent not later than 10:00 a.m. on the fourth Business Day prior to September 16, 2004 (or, in the case of a Failed Remarketing, not later than 10:00 a.m. on the Business Day immediately prior to the Subsequent Remarketing Date). Upon receipt thereof by the Agent, the Agent shall deliver such Opt-out Treasury Consideration to the Collateral Agent, which will, for the benefit of the Company, thereupon apply such Opt-out Treasury Consideration to secure such Holder's obligations under the Purchase Contracts. On the fourth Business Day immediately preceding

26

September 16, 2004, the Collateral Agent, pursuant to the terms of the Pledge Agreement, will deliver the Pledged Preferred Securities of such Holder to the Agent. Within three Business Days following the Remarketing Date, (i) if the remarketing was successful, the Agent shall distribute such Preferred Securities to the Holders thereof, and (ii) if there was a Failed Remarketing on such date, the Agent will deliver such Preferred Securities to the Collateral Agent, which will, for the benefit of the Company, thereupon apply such Preferred Securities to secure such Holders' obligations under the Purchase Contract and return the Opt-out Treasury Consideration delivered by such Holders to such Holders. A Holder that does not so deliver the Opt-out Treasury Consideration pursuant to this clause (iv) shall be deemed to have elected to participate in the remarketing. Pursuant to the procedures set forth in Section 4.5(c) of the Pledge Agreement, a Holder of Separate Preferred Securities, on or prior to the fifth Business Day immediately preceding September 16, 2004, but no earlier than the Payment Date immediately preceding September 16, 2004, may elect to have its Separate Preferred Securities remarketed by delivering the Separate Preferred Securities, together with a notice of such election, to the Custodial Agent.

(c)

Upon the maturity of the Pledged Treasury Securities underlying the Stripped Units and the Pledged Treasury Consideration underlying the Normal Units, on the Stock Purchase Date, the Collateral Agent shall remit to the Company an amount equal to the aggregate Purchase Price applicable to such Units, as payment for the Common Stock issuable upon settlement thereof without receiving any instructions from the Holders of such Units. In the event the payments in respect of the Pledged Treasury Securities or the Pledged Treasury Consideration, underlying a Unit is in excess of the Purchase Price of the Purchase Contract being settled thereby, the Collateral Agent will distribute such excess to the Agent for the benefit of the Holder of such Unit when received.



(d)

Any distribution to Holders of excess funds and interest described in paragraphs (b) and (c) above shall be payable at the office of the Agent in The City of New York maintained for that purpose or, at the option of the Holder or the holder of separate Preferred Securities, as applicable, by check mailed to the address of the Person entitled thereto at such address as it appears on the Register or by wire transfer to an account specified by the Holder or the holder of separate Preferred Securities, as applicable.



(e)

The obligations of each Holder to pay the Purchase Price are non-recourse obligations and except to the extent paid by Early Settlement or Merger Early Settlement, are payable solely out of the proceeds of any Collateral pledged to secure the obligations of the Holders and in no event will Holders be liable for any deficiency between such payments and the Purchase Price.



(f)

Notwithstanding anything to the contrary herein, the Company shall not be obligated to issue any Common Stock in respect of a Purchase Contract or deliver any certificates therefor to the Holder of the related Unit unless the Company shall have received payment in full of the aggregate Purchase Price for the shares of Common Stock to be purchased thereunder by such Holder in the manner herein set forth.

    Section 5.3.  Issuance of Shares of Common Stock.  Unless a Termination Event shall have occurred on or prior to the Stock Purchase Date or an Early Settlement or a Merger Early Settlement shall have occurred, on the Stock Purchase Date, upon its receipt of payment in full of the Purchase Price for the shares of Common Stock purchased by the Holders pursuant to the foregoing provisions of this Article and subject to Section 5.4(b), the Company shall issue and deposit with the Agent, for the benefit of the Holders of the Outstanding Units, one or more certificates representing the newly issued shares of Common Stock registered in the name of the Agent (or its nominee) as custodian for the Holders (such certificates for shares of Common Stock, together with any dividends or distributions

27

for which a record date and payment date for such dividend or distribution has occurred after the Stock Purchase Date, being hereinafter referred to as the "Purchase Contract Settlement Fund") to which the Holders are entitled hereunder. Subject to the foregoing, upon surrender of a Certificate to the Agent on or after the Stock Purchase Date, together with settlement instructions thereon duly completed and executed, the Holder of such Certificate shall be entitled to receive in exchange therefor a certificate representing that number of whole shares of Common Stock which such Holder is entitled to receive pursuant to the provisions of this Article V (after taking into account all Units then held by such Holder) together with cash in lieu of fractional shares as provided in Section 5.10 and any dividends or distributions with respect to such shares constituting part of the Purchase Contract Settlement Fund, but without any interest thereon, and the Certificate so surrendered shall forthwith be cancelled. Such shares shall be registered in the name of the Holder or the Holder's designee as specified in the settlement instructions provided by the Holder to the Agent. If any shares of Common Stock issued in respect of a Purchase Contract are to be registered to a Person other than the Person in whose name the Certificate evidencing such Purchase Contract is registered, no such registration shall be made unless the Person requesting such registration has paid any transfer and other taxes required by reason of such registration in a name other than that of the registered Holder of such Certificate or has established to the satisfaction of the Company that such tax either has been paid or is not payable.

    Section 5.4.  Adjustment of Settlement Rate.  (a) Adjustments for Dividends, Distributions, Stock Splits, Spin-Offs, Etc. (1) In case the Company shall pay or make a dividend or other distribution on the Common Stock in Common Stock, the Settlement Rate, as in effect at the opening of business on the day following the date fixed for the determination of stockholders entitled to receive such dividend or other distribution shall be increased by dividing such Settlement Rate by a fraction of which the numerator shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination and the denominator shall be the sum of such number of shares and the total number of shares constituting such dividend or other distribution, such increase to become effective immediately after the opening of business on the day following the date fixed for such determination. For the purposes of this paragraph (1), the number of shares of Common Stock at the time outstanding shall not include shares held in the treasury of the Company but shall include any shares issuable in respect of any scrip certificates issued in lieu of fractions of shares of Common Stock. The Company will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company.

    (2) In case the Company shall issue rights, options or warrants to all holders of its Common Stock (not being available on an equivalent basis to Holders of the Units upon settlement of the Purchase Contracts underlying such Units) entitling them, for a period expiring within 45 days after the record date for the determination of stockholders entitled to receive such rights, options or warrants, to subscribe for or purchase shares of Common Stock at a price per share less than the Current Market Price per share of the Common Stock on the date fixed for the determination of stockholders entitled to receive such rights, options or warrants (other than pursuant to a dividend reinvestment plan), the Settlement Rate in effect at the opening of business on the day following the date fixed for such determination shall be increased by dividing such Settlement Rate by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination plus the number of shares of Common Stock which the aggregate of the offering price of the total number of shares of Common Stock so offered for subscription or purchase would purchase at such Current Market Price and the denominator of which shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination plus the number of shares of Common Stock so offered for subscription or purchase, such increase to become effective immediately after the opening of business on the day following the date fixed for such determination. For the purposes of this paragraph (2), the number of shares of Common Stock at

28

any time outstanding shall not include shares held in the treasury of the Company but shall include any shares issuable in respect of any scrip certificates issued in lieu of fractions of shares of Common Stock. The Company shall not issue any such rights, options or warrants in respect of shares of Common Stock held in the treasury of the Company.

    (3) In case outstanding shares of Common Stock shall be subdivided or split into a greater number of shares of Common Stock, the Settlement Rate in effect at the opening of business on the day following the day upon which such subdivision or split becomes effective shall be proportionately increased, and, conversely, in case outstanding shares of Common Stock shall each be combined into a smaller number of shares of Common Stock, the Settlement Rate in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately reduced, such increase or reduction, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision, split or combination becomes effective.

    (4) (i) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock evidences of its indebtedness or assets (including securities, but excluding any rights or warrants referred to in paragraph (2) of this Section, any dividend or distribution paid exclusively in cash, any distribution of shares of capital stock of any class or series, or similar equity interests, of or relating to a subsidiary or other business unit in the case of a Spin-Off referred to in clause (ii) of this paragraph and any dividend or distribution referred to in paragraph (1) of this Section), the Settlement Rate shall be adjusted so that the same shall equal the rate determined by dividing the Settlement Rate in effect immediately prior to the close of business on the date fixed for the determination of stockholders entitled to receive such distribution by a fraction, the numerator of which shall be the Current Market Price per share of the Common Stock on the date fixed for such determination less the then fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution filed with the Agent) of the portion of the assets or evidences of indebtedness so distributed applicable to one share of Common Stock and the denominator of which shall be such Current Market Price per share of the Common Stock, such adjustment to become effective immediately prior to the opening of business on the day following the date fixed for the determination of stockholders entitled to receive such distribution. In any case in which this paragraph (4) is applicable, paragraph (2) of this Section shall not be applicable.

(ii)

In the case of a Spin-Off, the Settlement Rate in effect immediately before the close of business on the record date fixed for determination of stockholders entitled to receive that distribution will be increased by multiplying the Settlement Rate by a fraction, the numerator of which is the Current Market Price per share of the Common Stock plus the Fair Market Value of the portion of those shares of Capital Stock or similar equity interests so distributed applicable to one share of Common Stock and the denominator of which is the Current Market Price per share of the Common Stock. Any adjustment to the settlement rate under this paragraph 4(ii) will be determined at the earlier of (1) the tenth Trading Day from, and including, the effective date of the Spin-Off and (2) the date of the Initial Public Offering of the securities subject of the Spin-Off, if that Initial Public Offering is effected simultaneously with the Spin-Off, and shall be given retroactive effect to the opening of business on the day following the date fixed for determination of stockholders entitled to receive the Spin-Off Distribution.

    (5) In case the Company shall, (i) by dividend or otherwise, distribute to all holders of its Common Stock cash (excluding any cash that is distributed in a Reorganization Event to which Section 5.4(b) applies or as part of a distribution referred to in paragraph (4) of this Section) in an aggregate amount that, combined together with (ii) the aggregate amount of any other distributions to all holders of its Common Stock made exclusively in cash within the 12 months

29

preceding the date of payment of such distribution and in respect of which no adjustment pursuant to this paragraph (5) or paragraph (6) of this Section has been made and (iii) the aggregate of any cash plus the fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution) of consideration payable in respect of any tender or exchange offer by the Company or any of its subsidiaries for all or any portion of the Common Stock concluded within the 12 months preceding the date of payment of the distribution described in clause (i) above and in respect of which no adjustment pursuant to this paragraph (5) or paragraph (6) of this Section has been made, exceeds 15% of the product of the Current Market Price per share of the Common Stock on the date for the determination of holders of shares of Common Stock entitled to receive such distribution times the number of shares of Common Stock outstanding on such date, then, and in each such case, immediately after the close of business on such date for determination, the Settlement Rate shall be increased so that the same shall equal the rate determined by dividing the Settlement Rate in effect immediately prior to the close of business on the date fixed for determination of the stockholders entitled to receive such distribution by a fraction (i) the numerator of which shall be equal to the Current Market Price per share of the Common Stock on the date fixed for such determination less an amount equal to the quotient of (x) the combined amount distributed or payable in the transactions described in clauses (i), (ii) and (iii) above and (y) the number of shares of Common Stock outstanding on such date for determination and (ii) the denominator of which shall be equal to the Current Market Price per share of the Common Stock on such date for determination.

    (6) In case (i) a tender or exchange offer made by the Company or any subsidiary of the Company for all or any portion of the Common Stock shall expire and such tender or exchange offer (as amended upon the expiration thereof) shall require the payment to stockholders (based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of Purchased Shares) of an aggregate consideration having a fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution) that combined together with (ii) the aggregate of the cash plus the fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution), as of the expiration of such tender or exchange offer, of consideration payable in respect of any other tender or exchange offer, by the Company or any subsidiary of the Company for all or any portion of the Common Stock expiring within the 12 months preceding the expiration of such tender or exchange offer and in respect of which no adjustment pursuant to paragraph (5) of this Section or this paragraph (6) has been made and (iii) the aggregate amount of any distributions to all holders of the Company's Common Stock made exclusively in cash within the 12 months preceding the expiration of such tender or exchange offer and in respect of which no adjustment pursuant to paragraph (5) of this Section or this paragraph (6) has been made, exceeds 15% of the product of the Current Market Price per share of the Common Stock as of the last time (the "Expiration Time") tenders could have been made pursuant to such tender or exchange offer (as it may be amended) times the number of shares of Common Stock outstanding (including any tendered shares) on the Expiration Time, then, and in each such case, immediately prior to the opening of business on the day after the date of the Expiration Time, the Settlement Rate shall be adjusted so that the same shall equal the rate determined by dividing the Settlement Rate immediately prior to the close of business on the date of the Expiration Time by a fraction (i) the numerator of which shall be equal to (a) the product of (i) the Current Market Price per share of the Common Stock on the date of the Expiration Time and (ii) the number of shares of Common Stock outstanding (including any tendered shares) on the Expiration Time less (b) the amount of cash plus the fair market value (determined as aforesaid) of the aggregate consideration payable to stockholders based on the transactions described in clauses (i), (ii) and (iii) above (assuming in the case of clause (i) the acceptance, up to any maximum specified in the terms of the tender or exchange offer, of Purchased Shares), and (ii) the denominator of which shall be

30

equal to the product of (a) the Current Market Price per share of the Common Stock as of the Expiration Time and (b) the number of shares of Common Stock outstanding (including any tendered shares) as of the Expiration Time less the number of all shares validly tendered and not withdrawn as of the Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the "Purchased Shares").

    (7) The reclassification of Common Stock into securities including securities other than Common Stock (other than any reclassification upon a Reorganization Event to which Section 5.4(b) applies) shall be deemed to involve (a) a distribution of such securities other than Common Stock to all holders of Common Stock (and the effective date of such reclassification shall be deemed to be "the date fixed for the determination of stockholders entitled to receive such distribution" and the "date fixed for such determination" within the meaning of paragraph (4) of this Section), and (b) a subdivision, split or combination, as the case may be, of the number of shares of Common Stock outstanding immediately prior to such reclassification into the number of shares of Common Stock outstanding immediately thereafter (and the effective date of such reclassification shall be deemed to be "the day upon which such subdivision or split becomes effective" or "the day upon which such combination becomes effective," as the case may be, and "the day upon which such subdivision, split or combination becomes effective" within the meaning of paragraph (3) of this Section).

    (8) "Current Market Price." The "Current Market Price" of the Common Stock means (a) on any day the average of the Sales Prices for the 5 consecutive Trading Days preceding the earlier of the day preceding the day in question and the day before the "ex date" with respect to the issuance or distribution requiring computation, (b) in the case of any Spin-Off that is effected simultaneously with an Initial Public Offering of the securities being distributed in the Spin-Off, the Sale Price of the Common Stock on the Trading Day on which the initial public offering price of the securities being distributed in the Spin-Off is determined, and (c) in the case of any other Spin-Off, the average of the Sale Prices of the Common Stock over the first 10 Trading Days after the effective date of such Spin-Off. For purposes of this paragraph, the term "ex date," when used with respect to any issuance or distribution, shall mean the first date on which the Common Stock trades regular way on such exchange or in such market without the right to receive such issuance or distribution.

    (9) All adjustments to the Settlement Rate shall be calculated to the nearest 1/10,000th of a share of Common Stock (or if there is not a nearest 1/10,000th of a share to the next lower 1/10,000th of a share). No adjustment in the Settlement Rate shall be required unless such adjustment would require an increase or decrease of at least one percent therein; provided, however, that any adjustments which by reason of this subparagraph are not required to be made shall be carried forward and taken into account in any subsequent adjustment. If an adjustment is made to the Settlement Rate pursuant to paragraph (1), (2), (3), (4), (5), (6), (7) or (10) of this Section 5.4(a), an adjustment shall also be made to the Average Trading Price solely to determine which of clauses (a), (b) or (c) of the definition of Settlement Rate in Section 5.1 will apply on the Stock Purchase Date. Such adjustment shall be made by multiplying the Average Trading Price by a fraction, the numerator of which shall be the Settlement Rate immediately after such adjustment pursuant to paragraph (1), (2), (3), (4), (5), (6), (7) or (10) of this Section 5.4(a) and the denominator of which shall be the Settlement Rate immediately before such adjustment; provided, that if such adjustment to the Settlement Rate is required to be made pursuant to the occurrence of any of the events contemplated by paragraph (1), (2), (3), (4), (5), (7) or (10) of this Section 5.4(a) during the period taken into consideration for determining the Average Trading Price, appropriate and customary adjustments shall be made to the Settlement Rate.

    (10) The Company may make such increases in the Settlement Rate, in addition to those required by this Section, as it considers to be advisable in order to avoid or diminish the effect of

31

any income tax to any holders of shares of Common Stock resulting from any dividend or distribution of stock or issuance of rights or warrants to purchase or subscribe for stock or from any event treated as such for income tax purposes or for any other reasons.

    (b) Adjustment for Consolidation, Merger or Other Reorganization Event. In the event of (i) any consolidation or merger of the Company with or into another Person (other than a merger or consolidation in which the Company is the continuing corporation and in which the Common Stock outstanding immediately prior to the merger or consolidation is not exchanged for cash, securities or other property of the Company or another corporation), (ii) any sale, transfer, lease or conveyance to another Person of the property of the Company as an entirety or substantially as an entirety, (iii) any statutory exchange of securities of the Company with another Person (other than in connection with a merger or acquisition) or (iv) any liquidation, dissolution or winding up of the Company other than as a result of or after the occurrence of a Termination Event (any such event, a "Reorganization Event") each share of Common Stock covered by each Purchase Contract forming a part of a Unit immediately prior to such Reorganization Event shall, after such Reorganization Event, be converted for purposes of the Purchase Contract into the kind and amount of securities, cash and other property receivable in such Reorganization Event (without any interest thereon, and without any right to dividends or distribution thereon which have a record date that is prior to the Stock Purchase Date) per share of Common Stock by a holder of Common Stock that (i) is not a Person with which the Company consolidated or into which the Company merged or which merged into the Company or to which such sale or transfer was made, as the case may be (any such Person, a "Constituent Person"), or an Affiliate of a Constituent Person to the extent such Reorganization Event provides for different treatment of Common Stock held by Affiliates of the Company and non-Affiliates, and (ii) failed to exercise his rights of election, if any, as to the kind or amount of securities, cash and other property receivable upon such Reorganization Event (provided that if the kind or amount of securities, cash and other property receivable upon such Reorganization Event is not the same for each share of Common Stock held immediately prior to such Reorganization Event by other than a Constituent Person or an Affiliate thereof and in respect of which such rights of election shall not have been exercised ("Non-electing Share"), then for the purpose of this Section the kind and amount of securities, cash and other property receivable upon such Reorganization Event by each Non-electing Share shall be deemed to be the kind and amount so receivable per share by a plurality of the Non-electing Shares). On the Stock Purchase Date, the Settlement Rate then in effect will be applied to the value on the Stock Purchase Date of such securities, cash or other property.

The Company covenants to and agrees with the Holders that it shall not cause or permit to occur any Reorganization Event and no Reorganization Event shall become effective unless and until the Person formed by such consolidation, merger, or exchange or the Person which acquires the assets of the Company or, in the event of a liquidation or dissolution of the Company, the Company or a liquidating trust created in connection therewith, shall execute and deliver to the Agent an agreement supplemental hereto providing that the Holder of each Outstanding Unit shall have the rights provided by this Section 5.4. Such supplemental agreement shall provide for adjustments which, for events subsequent to the effective date of such supplemental agreement, shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section. The above provisions of this Section shall similarly apply to successive Reorganization Events.

    Section 5.5.  Notice of Adjustments and Certain Other Events.  (a) Whenever the Settlement Rate is adjusted as herein provided, the Company shall:

(i)

forthwith compute the Settlement Rate in accordance with Section 5.4 and prepare and transmit to the Agent an Officer's Certificate setting forth the Settlement Rate, the method of calculation thereof in reasonable detail, and the facts requiring such adjustment and upon which such adjustment is based; and

32

(ii)

within 10 Business Days following the occurrence of an event that requires an adjustment to the Settlement Rate pursuant to Section 5.4 (or if the Company is not aware of such occurrence, as soon as practicable after becoming so aware), provide a written notice to the Holders of the Units of the occurrence of such event and a statement in reasonable detail setting forth the method by which the adjustment to the Settlement Rate was determined and setting forth the adjusted Settlement Rate.

    (b) The Agent shall not at any time be under any duty or responsibility to any Holder of Units to determine whether any facts exist which may require any adjustment of the Settlement Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed in making the same. The Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities or property, which may at the time be issued or delivered with respect to any Purchase Contract; and the Agent makes no representation with respect thereto. The Agent shall not be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock pursuant to a Purchase Contract or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article.

    Section 5.6.  Termination Event; Notice.  The Purchase Contracts and all obligations and rights of the Company and the Holders thereunder, including the rights and obligations of Holders to purchase Common Stock, shall immediately and automatically terminate, without the necessity of any notice or action by any Holder, the Agent or the Company, if, on or prior to the Stock Purchase Date, a Termination Event shall have occurred. Upon and after the occurrence of a Termination Event, the Normal Units shall thereafter represent the right to receive the Preferred Securities or the appropriate Treasury Consideration, as the case may be, forming a part of such Normal Units, and the Stripped Units shall thereafter represent the right to receive the Treasury Securities forming a part of such Stripped Units, in each case in accordance with the provisions of Section 4.3 of the Pledge Agreement. Upon the occurrence of a Termination Event, the Company shall promptly but in no event later than two Business Days thereafter give written notice to the Agent, the Collateral Agent and to the Holders, at their addresses as they appear in the Register.

33

    Section 5.7.  Early Settlement.  (a) Subject to and upon compliance with the provisions of this Section 5.7, Purchase Contracts underlying Units having an aggregate Stated Amount equal to $1,000 or an integral multiple thereof may, at the option of the Holder thereof, be settled early ("Early Settlement") on or prior to the seventh Business Day immediately preceding December 16, 2004 or any Subsequent Remarketing Date; provided however, that if a Tax Event Redemption has occurred and the Treasury Consideration has become a component of the Normal Units, Purchase Contracts underlying Normal Units may be settled early, on or prior to the second Business Day immediately preceding the Stock Purchase Date, but only in an aggregate amount of $1,000 or in an integral multiple thereof. In order to exercise the right to effect Early Settlement with respect to any Purchase Contracts, the Holder of the Certificate evidencing the related Units shall deliver such Certificate to the Agent at the Corporate Trust Office duly endorsed for transfer to the Company or in blank with the form of Election to Settle Early on the reverse thereof duly completed and accompanied by payment (payable to the Company in immediately available funds in an amount (the "Early Settlement Amount") equal to the product of (a) the Stated Amount of such Units times (b) the number of Purchase Contracts with respect to which the Holder has elected to effect Early Settlement. No payment or adjustment shall be made upon Early Settlement of any Purchase Contract on account of dividends on the Common Stock issued upon such Early Settlement. If the foregoing requirements are first satisfied with respect to Purchase Contracts underlying any Unit at or prior to 5:00 p.m., New York City time, on a Business Day, such day shall be the "Early Settlement Date" with respect to such Unit and if such requirements are first satisfied after 5:00 p.m., New York City time, on a Business Day or on a day that is not a Business Day, the "Early Settlement Date" with respect to such Units shall be the next succeeding Business Day.

    (b) Upon Early Settlement of any Purchase Contract by the Holder of the related Units, the Company shall issue, and the Holder shall be entitled to receive, 1.2860 shares of Common Stock on account of such Purchase Contract (the "Early Settlement Rate"). The Early Settlement Rate shall be adjusted in the same manner and at the same time as the Settlement Rate is adjusted. As promptly as practicable after Early Settlement of Purchase Contracts in accordance with the provisions of this Section 5.7, the Company shall issue and shall deliver to the Agent at the Corporate Trust Office a certificate or certificates for the full number of shares of Common Stock issuable upon such Early Settlement together with payment in lieu of any fraction of a share, as provided in Section 5.10.

    (c) No later than the third Business Day after the applicable Early Settlement Date the Company shall cause (i) the shares of Common Stock issuable upon Early Settlement of Purchase Contracts to be issued and delivered, and (ii) the related Pledged Preferred Securities or Pledged Treasury Consideration, in the case of Normal Units, or the related Pledged Treasury Securities, in the case of Stripped Units, to be released from the Pledge by the Collateral Agent and transferred, in each case, to the Agent for delivery to the Holder thereof or the Holder's designee.

    (d) Upon Early Settlement of any Purchase Contracts, and subject to receipt of shares of Common Stock from the Company and the Pledged Preferred Securities, Pledged Treasury Consideration or Pledged Treasury Securities, as the case may be, from the Collateral Agent, as applicable, the Agent shall, in accordance with the instructions provided by the Holder thereof on the applicable form of Election to Settle Early on the reverse of the Certificate evidencing the related Units, (i) transfer to the Holder the Pledged Preferred Securities, Pledged Treasury Consideration or Pledged Treasury Securities, as the case may be, forming a part of such Units, and (ii) deliver to the Holder a certificate or certificates for the full number of shares of Common Stock issuable upon such Early Settlement together with payment in lieu of any fraction of a share, as provided in Section 5.10.

    (e) In the event that Early Settlement is effected with respect to Purchase Contracts underlying less than all the Units evidenced by a Certificate, upon such Early Settlement the

34

Company shall execute and the Agent shall authenticate, countersign and deliver to the Holder thereof, at the expense of the Company, a Certificate evidencing the Units as to which Early Settlement was not effected.

    Section 5.8.  Early Settlement Upon Merger.  (a) In the event of a merger or consolidation of the Company of the type described in clause (i) of Section 5.4(b) in which the Common Stock outstanding immediately prior to such merger or consolidation is exchanged for consideration consisting of at least 30% cash or cash equivalents (any such event a "Cash Merger"), then the Company (or the successor to the Company hereunder) shall be required to offer the Holder of each Unit the right to settle the Purchase Contract underlying such Unit prior to the Stock Purchase Date ("Merger Early Settlement") as provided herein. On or before the fifth Business Day after the consummation of a Cash Merger, the Company or, at the request and expense of the Company, the Agent, shall give all Holders notice of the occurrence of the Cash Merger and of the right of Merger Early Settlement arising as a result thereof. The Company shall also deliver a copy of such notice to the Agent and the Collateral Agent.

    Each such notice shall contain:

(i)

the date, which shall be not less than 20 nor more than 30 calendar days after the date of such notice, on which the Merger Early Settlement will be effected (the "Merger Early Settlement Date");



(ii)

the date, which shall be one Business Day prior to the Merger Early Settlement Date, by which the Merger Early Settlement right must be exercised;



(iii)

the Settlement Rate in effect as a result of such Cash Merger and the kind and amount of securities, cash and other property receivable by the Holder upon settlement of each Purchase Contract pursuant to Section 5.4(b);



(iv)

a statement to the effect that all or a portion of the Purchase Price payable by the Holder to settle the Purchase Contract will be offset against the amount of cash so receivable upon exercise of Merger Early Settlement, as applicable; and



(v)

the instructions a Holder must follow to exercise the Merger Early Settlement right.

    (b) To exercise a Merger Early Settlement right, a Holder shall deliver to the Agent at the Corporate Trust Office on or before 5:00 p.m., New York City time, on the date specified in the notice the Certificate(s) evidencing the Units with respect to which the Merger Early Settlement right is being exercised duly endorsed for transfer to the Company or in blank with the form of Election to Settle Early on the reverse thereof duly completed and accompanied by payment (payable to the Company in immediately available funds in an amount equal to the Early Settlement Amount less the amount of cash that otherwise would be deliverable by the Company or its successor upon settlement of the Purchase Contract in lieu of Common Stock pursuant to Section 5.4(b) and as described in the notice to Holders (the "Merger Early Settlement Amount").

    (c) On the Merger Early Settlement Date, the Company shall deliver or cause to be delivered (i) the net cash, securities and other property to be received by such exercising Holder, equal to the Settlement Rate as adjusted pursuant to Section 5.4, in respect of the number of Purchase Contracts for which such Merger Early Settlement right was exercised, and (ii) the related Pledged Preferred Securities or Pledged Treasury Consideration, in the case of Normal Units, or Pledged Treasury Securities, in the case of Stripped Units, to be released from the Pledge by the Collateral Agent and transferred, in each case, to the Agent for delivery to the Holder thereof or its designee. In the event a Merger Early Settlement right shall be exercised by a Holder in accordance with the terms hereof, all references herein to Stock Purchase Date shall be deemed to refer to such Merger Early Settlement Date.

35

    (d) Upon Merger Early Settlement of any Purchase Contracts, and subject to receipt of such net cash, securities or other property from the Company and the Pledged Preferred Securities, Pledged Treasury Consideration or Pledged Treasury Securities, as the case may be, from the Collateral Agent, as applicable, the Agent shall, in accordance with the instructions provided by the Holder thereof on the applicable form of Election to Settle Early on the reverse of the Certificate evidencing the related Units, (i) transfer to the Holder the Pledged Preferred Securities, Pledged Treasury Consideration or Pledged Treasury Securities, as the case may be, forming a part of such Units, and (ii) deliver to the Holder such net cash, securities or other property issuable upon such Merger Early Settlement together with payment in lieu of any fraction of a share, as provided in Section 5.10.

    (e) In the event that Merger Early Settlement is effected with respect to Purchase Contracts underlying less than all the Units evidenced by a Certificate, upon such Merger Early Settlement the Company (or the successor to the Company hereunder) shall execute and the Agent shall authenticate, countersign and deliver to the Holder thereof, at the expense of the Company, a Certificate evidencing the Units as to which Merger Early Settlement was not effected.

    Section 5.9.  Charges and Taxes.  The Company will pay all stock transfer and similar taxes attributable to each issuance and delivery of the shares of Common Stock pursuant to the Purchase Contracts; provided, that the Company shall not be required to pay any such tax or taxes which may be payable in respect of any exchange of or substitution for a Certificate evidencing a Unit or any issuance of a share of Common Stock in a name other than that of the registered Holder of a Certificate surrendered in respect of the Units evidenced thereby, other than in the name of the Agent, as custodian for such Holder, and the Company shall not be required to issue or deliver such share certificates or Certificates unless and until the Person or Persons requesting the transfer or issuance thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid.

    Section 5.10.  No Fractional Shares.  No fractional shares or scrip or book-entry notations representing fractional shares of Common Stock shall be issued, delivered or recorded upon settlement on the Stock Purchase Date or upon Early Settlement or Merger Early Settlement of any Purchase Contracts. If Certificates evidencing more than one Purchase Contract shall be surrendered for settlement at one time by the same Holder, the number of full shares of Common Stock which shall be delivered upon settlement shall be computed on the basis of the aggregate number of Purchase Contract or Purchase Contracts evidenced by the Certificates so surrendered. Instead of any fractional share of Common Stock which would otherwise be deliverable upon settlement of any Purchase Contracts on the applicable Settlement Date or upon Early Settlement or Merger Early Settlement, the Company shall, through the Agent, make a cash payment to the Holder in respect of such fractional shares in an amount equal to the product of such fraction of a share times the Average Trading Price. The Company shall provide the Agent from time to time with sufficient funds to permit the Agent to make all cash payments required by this Section 5.10 on or prior to the applicable Settlement date.

ARTICLE VI
REMEDIES

    Section 6.1.  Unconditional Right of Holders to Purchase Common Stock.  The Holder of any Unit shall have the right, which is absolute and unconditional to purchase Common Stock pursuant to the Purchase Contract constituting a part of such Unit and to institute suit for the enforcement of any such right to purchase Common Stock, and such rights shall not be impaired without the consent of such Holder.

    Section 6.2.  Restoration of Rights and Remedies.  If any Holder has instituted any proceeding to enforce any right or remedy under this Agreement and such proceeding has been discontinued or

36

abandoned for any reason, or has been determined adversely to such Holder, then and in every such case, subject to any determination in such proceeding, the Company and such Holder shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of such Holder shall continue as though no such proceeding had been instituted.

    Section 6.3.  Rights and Remedies Cumulative.  Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Certificates in the last paragraph of Section 3.10, no right or remedy herein conferred upon or reserved to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, 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 prevent the concurrent assertion or employment of any other appropriate right or remedy.

    Section 6.4.  Delay or Omission Not Waiver.  No delay or omission of any Holder to exercise any right or remedy upon a default shall impair any such right or remedy or constitute a waiver of any such right. Every right and remedy given by this Article or by law to the Holders may be exercised from time to time, and as often as may be deemed expedient, by such Holders.

    Section 6.5.  Undertaking for Costs.  All parties to this Agreement agree, and each Holder of a Unit, by its acceptance of such Unit shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Agreement, or in any suit against the Agent for any action taken, suffered or omitted by it as Agent, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys' fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided, that the provisions of this Section shall not apply to any suit instituted by the Company, to any suit instituted by the Agent, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% of the Outstanding Units, or to any suit instituted by any Holder for the enforcement of distributions on any Preferred Securities on or after the respective Payment Date therefor in respect of any Unit held by such Holder, or for enforcement of the right to purchase shares of Common Stock under the Purchase Contract constituting part of any Unit held by such Holder.

    Section 6.6.  Waiver of Stay or Extension 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 wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Agreement; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, but will suffer and permit the execution of every such power as though no such law had been enacted.

Form of Face of Normal Units Certificate

    This Normal Units Certificate certifies that Cede & Co. is the registered Holder of the number of Normal Units set forth above. Each Normal Unit represents (i) either (a) beneficial ownership by the Holder of one 7.50% Preferred Security (the "Preferred Security") of Boise Cascade Trust I, a Delaware statutory business trust (the "Trust"), having a stated liquidation amount of $50, subject to the Pledge of such Preferred Security by such Holder pursuant to the Pledge Agreement, or (b) if a Tax Event Redemption has occurred or the Preferred Security has been remarketed by the Remarketing Agent (or if the Holder has elected not to have the Preferred Security remarketed by delivering the appropriate Treasury Consideration specified by the Remarketing Agent), the appropriate Treasury Consideration, subject to the Pledge of such Treasury Consideration by such Holder pursuant to the Pledge Agreement, and (ii) the rights and obligations of the Holder under one Purchase Contract with Boise Cascade Corporation, a Delaware corporation (the "Company"). All capitalized terms used herein which are defined in the Purchase Contract Agreement have the meaning set forth therein.

    Pursuant to the Pledge Agreement, the Preferred Security or the appropriate Treasury Consideration, as the case may be, constituting part of each Normal Unit evidenced hereby has been pledged to the Collateral Agent, for the benefit of the Company, to secure the obligations of the Holder under the Purchase Contract comprising a part of such Normal Unit.

    The Pledge Agreement provides that all payments in respect of the Pledged Preferred Securities or Pledged Treasury Consideration received by the Collateral Agent shall be paid by the Collateral Agent by wire transfer in same day funds (i) in the case of (a) quarterly cash distributions on Normal Units which include Pledged Preferred Securities or Pledged Treasury Consideration and (b) any payments of the Preferred Securities or Treasury Consideration, as the case may be, that have been released from the Pledge pursuant to the Pledge Agreement, to the Agent to the account designated by the Agent, no later than 10:00 a.m., New York City time, on the Business Day such payment is received by the Collateral Agent (provided that in the event such payment is received by the Collateral Agent on a day that is not a Business Day or after 9:00 a.m., New York City time, on a Business Day, then such

A–1

payment shall be made no later than 9:30 a.m., New York City time, on the next succeeding Business Day) and (ii) in the case of payments in respect of any Pledged Preferred Securities or Pledged Treasury Consideration, as the case may be, to be paid upon settlement of such Holder's obligations to purchase Common Stock under the Purchase Contract, to the Company on the Stock Purchase Date (as defined herein) in accordance with the terms of the Pledge Agreement, in full satisfaction of the respective obligations of the Holders of the Normal Units of which such Pledged Preferred Securities or Pledged Treasury Consideration, as the case may be, are a part under the Purchase Contracts forming a part of such Normal Units. Quarterly distributions on Normal Units which include Pledged Preferred Securities or Pledged Treasury Consideration, as the case may be, which are payable quarterly in arrears on March 16, June 16, September 16, and December 16 each year, commencing March 16, 2002 (a "Payment Date"), shall, subject to receipt thereof by the Agent from the Collateral Agent, be paid to the Person in whose name this Normal Units Certificate (or a Predecessor Normal Units Certificate) is registered at the close of business on the Record Date for such Payment Date.

    Each Purchase Contract evidenced hereby obligates the Holder of this Normal Units Certificate to purchase, and the Company to sell, on December 16, 2004 (the "Stock Purchase Date"), at a price equal to $50 (the "Stated Amount"), a number of shares of common stock, $2.50 par value per share ("Common Stock"), of the Company, equal to the Settlement Rate, unless on or prior to the Stock Purchase Date there shall have occurred a Termination Event or an Early Settlement or Merger Early Settlement with respect to the Normal Units of which such Purchase Contract is a part, all as provided in the Purchase Contract Agreement and more fully described on the reverse hereof.

By: BNY WESTERN TRUST COMPANY, as Purchase Contract Agent
By:
	Authorized Signatory

A–4

(Form of Reverse of Normal Units Certificate)

    Each Purchase Contract evidenced hereby is governed by a Purchase Contract Agreement, dated as of December 5, 2001 (as may be supplemented from time to time, the "Purchase Contract Agreement"), between the Company and BNY Western Trust Company, as Purchase Contract Agent (including its successors thereunder, herein called the "Agent"), to which Purchase Contract Agreement and supplemental agreements thereto reference is hereby made for a description of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Agent, the Company, and the Holders and of the terms upon which the Normal Units Certificates are, and are to be, executed and delivered.

    Each Purchase Contract evidenced hereby obligates the Holder of this Normal Units Certificate to purchase, and the Company to sell, on the Stock Purchase Date at a price equal to $50 (the "Purchase Price"), a number of shares of Common Stock of the Company equal to the Settlement Rate, unless, on or prior to the Stock Purchase Date, there shall have occurred a Termination Event or an Early Settlement or Merger Early Settlement with respect to the Unit of which such Purchase Contract is a part. The "Settlement Rate" is equal to (a) if the Average Trading Price (as defined below) is greater than $38.88 (the "Threshold Appreciation Price"), 1.2860 shares of Common Stock per Purchase Contract, (b) if the Average Trading Price is less than the Threshold Appreciation Price but is greater than $31.87, the number of shares of Common Stock per Purchase Contract equal to the Stated Amount divided by the Average Trading Price and (c) if the Average Trading Price is less than $31.87, 1.5689 shares of Common Stock per Purchase Contract, in each case subject to adjustment as provided in the Purchase Contract Agreement. No fractional shares of Common Stock will be issued upon settlement of Purchase Contracts, as provided in the Purchase Contract Agreement.

    The "Average Trading Price" means the average of the Closing Price per share of Common Stock on each of the 20 consecutive Trading Days ending on the third Trading Day immediately preceding the Stock Purchase Date.

    The "Closing Price" of the Common Stock on any date of determination means the closing sale price (or, if no closing price is reported, the last reported sale price) of the Common Stock on the New York Stock Exchange (the "NYSE") on such date or, if the Common Stock is not listed for trading on the NYSE on any such date, as reported in the composite transactions for the principal United States securities exchange on which the Common Stock is so listed, or if the Common Stock is not so listed on a United States national or regional securities exchange, as reported by The Nasdaq Stock Market, or, if the Common Stock is not so reported, the last quoted bid price for the Common Stock in the over-the-counter market as reported by the National Quotation Bureau or similar organization, or, if such bid price is not available, the market value of the Common Stock on such date as determined by a nationally recognized independent investment banking firm retained for this purpose by the Company.

    A "Trading Day" means a day on which the Common Stock (a) is not suspended from trading on any national or regional securities exchange or association or over-the-counter market at the close of business and (b) has traded at least once on the national or regional securities exchange or association or over-the-counter market that is the primary market for the trading of the Common Stock.

    Each Purchase Contract evidenced hereby may be settled prior to the Stock Purchase Date through Early Settlement or Merger Early Settlement, in accordance with the terms of the Purchase Contract Agreement.

    In accordance with the terms of the Purchase Contract Agreement, the Holder of this Normal Units Certificate shall pay the Purchase Price for the shares of Common Stock purchased pursuant to each Purchase Contract evidenced hereby (i) by effecting an Early Settlement or Merger Early Settlement, (ii) by application of payments received in respect of the Pledged Treasury Consideration acquired from the proceeds of a remarketing of the related Pledged Preferred Securities underlying the

A–5

Normal Units represented by this Normal Units Certificate or (iii) if the Holder has elected not to participate in the remarketing, by application of payments received in respect of the Pledged Treasury Consideration deposited by such Holder in respect of such Purchase Contract. If, as provided in the Purchase Contract Agreement, upon the occurrence of a Failed Remarketing the Collateral Agent, for the benefit of the Company, exercises its rights as a secured creditor with respect to the Pledged Preferred Securities related to this Normal Units Certificate, any accumulated and unpaid distributions on such Pledged Preferred Securities will become payable by the Company to the Holder of this Normal Units Certificate in the manner provided for in the Purchase Contract Agreement.

    The Company shall not be obligated to issue any shares of Common Stock in respect of a Purchase Contract or deliver any certificates therefor to the Holder unless it shall have received payment in full of the aggregate Purchase Price for the shares of Common Stock to be purchased thereunder in the manner herein set forth.

    Under the terms of the Pledge Agreement, the Agent will be entitled to exercise the voting and any other consensual rights pertaining to the Pledged Preferred Securities. Upon receipt of notice of any meeting at which holders of Preferred Securities are entitled to vote or upon the solicitation of consents, waivers or proxies of holders of Preferred Securities, the Agent shall, as soon as practicable thereafter, mail to the Holders of Normal Units a notice (a) containing such information as is contained in the notice or solicitation, (b) stating that each such Holder on the record date set by the Agent therefor (which, to the extent possible, shall be the same date as the record date for determining the holders of Preferred Securities entitled to vote) shall be entitled to instruct the Agent as to the exercise of the voting rights pertaining to the Pledged Preferred Securities constituting a part of such Holder's Normal Units and (c) stating the manner in which such instructions may be given. Upon the written request of the Holders of Normal Units on such record date, the Agent shall endeavor insofar as practicable to vote or cause to be voted, in accordance with the instructions set forth in such requests, the maximum number of Pledged Preferred Securities as to which any particular voting instructions are received. In the absence of specific instructions from the Holder of a Normal Unit, the Agent shall abstain from voting the Pledged Preferred Security evidenced by such Normal Unit.

    Upon the occurrence of a Tax Event Redemption prior to the Stock Purchase Date, the Redemption Price payable on the Redemption Date with respect to the Preferred Securities shall be delivered to the Collateral Agent in exchange for the Preferred Securities. Thereafter, pursuant to the terms of the Pledge Agreement, the Collateral Agent for the benefit of the Company will apply an amount equal to the Redemption Amount of such Redemption Price to purchase, the Treasury Consideration and promptly remit the remaining portion of such Redemption Price to the Agent for payment to the Holders of such Normal Units.

    Following the occurrence of a Tax Event Redemption prior to the Stock Purchase Date, the Holders of Normal Units and the Collateral Agent shall have such security interests rights and obligations with respect to the Treasury Consideration as the Holder of Normal Units and the Collateral Agent had in respect of the Preferred Securities, as the case may be, subject to the Pledge thereof as provided in Articles II, III, IV, V and VI, of the Pledge Agreement and any reference herein to the Preferred Securities shall be deemed to be reference to such Treasury Consideration.

    Upon a voluntary or involuntary dissolution of the Trust, a principal amount of the Senior Debentures constituting the assets of the Trust and underlying the Pledged Preferred Securities equal to the aggregate Stated Amount of the Pledged Preferred Securities shall be delivered to the Collateral Agent in exchange for Pledged Preferred Securities. Thereafter, the Senior Debentures shall be held by the Collateral Agent to secure the obligations of each Holder of Normal Units to purchase shares of Common Stock under the Purchase Contracts constituting a part of such Normal Units. Following a voluntary or involuntary dissolution of the Trust, the Holders and the Collateral Agent shall have such security interests, rights and obligations with respect to the Senior Debentures as the Holders and the

A–6

Collateral Agent had in respect of the Pledged Preferred Securities, and any reference in the Purchase Contract Agreement or Pledge Agreement to the Preferred Securities or Pledged Preferred Securities shall be deemed to be a reference to the Senior Debentures.

    The Normal Units Certificates are issuable only in registered form and only in denominations of a single Normal Unit and any integral multiple thereof. The transfer of any Normal Units Certificate will be registered and Normal Units Certificates may be exchanged as provided in the Purchase Contract Agreement. The Normal Units Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents permitted by the Purchase Contract Agreement. No service charge shall be required for any such registration of transfer or exchange, but the Company and the Agent may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. The Holder of a Normal Unit may substitute for the Pledged Preferred Securities or Pledged Treasury Consideration securing its obligations under the related Purchase Contract Treasury Securities in accordance with the terms of the Purchase Contract Agreement and the Pledge Agreement. From and after such Collateral Substitution, the Unit for which such Pledged Treasury Securities secures the Holder's obligation under the Purchase Contract shall be referred to as a "Stripped Unit." A Holder that elects to substitute a Treasury Security for Pledged Preferred Securities or Pledged Treasury Consideration, thereby creating Stripped Units, shall be responsible for any fees or expenses payable in connection therewith. Except as provided in the Purchase Contract Agreement, for so long as the Purchase Contract underlying a Normal Unit remains in effect, such Normal Unit shall not be separable into its constituent parts, and the rights and obligations of the Holder of such Normal Units in respect of the Pledged Preferred Security or Pledged Treasury Consideration, as the case may be, and Purchase Contract constituting such Normal Unit may be transferred and exchanged only as a Normal Unit.

    A Holder of Stripped Units may reestablish Normal Units by delivering to the Collateral Agent Preferred Securities or the appropriate Treasury Consideration in exchange for the release of the Pledged Treasury Securities in accordance with the terms of the Purchase Contract Agreement and the Pledge Agreement.

    The Purchase Contracts and all obligations and rights of the Company and the Holders thereunder shall immediately and automatically terminate, without the necessity of any notice or action by any Holder, the Agent or the Company, if, on or prior to the Stock Purchase Date, a Termination Event shall have occurred. Upon the occurrence of a Termination Event, the Company shall promptly but in no event later than two Business Days thereafter give written notice to the Agent, the Collateral Agent and to the Holders, at their addresses as they appear in the Normal Units Register. Upon and after the occurrence of a Termination Event, the Collateral Agent shall release the Pledged Preferred Securities or Pledged Treasury Consideration, as the case may be, from the Pledge in accordance with the provisions of the Pledge Agreement.

    Subject to and upon compliance with the provisions of the Purchase Contract Agreement, at the option of the Holder thereof, Purchase Contracts underlying Securities having an aggregate Stated Amount equal to $1,000 or an integral multiple thereof may be settled early ("Early Settlement") as provided in the Purchase Contract Agreement; provided, however, that if a Tax Event Redemption has occurred and the Treasury Consideration has become a component of the Normal Units, Holders may early settle Normal Units only in integral multiples of 20 Normal Units. In order to exercise the right to effect Early Settlement with respect to any Purchase Contracts evidenced by this Normal Unit Certificate, the Holder of this Normal Unit Certificate shall deliver this Normal Unit Certificate to the Agent at the Corporate Trust Office duly endorsed for transfer to the Company or in blank with the form of Election to Settle Early set forth below duly completed and accompanied by payment in the form of immediately available funds payable to the order of the Company in an amount (the "Early Settlement Amount") equal to the product of (A) the Stated Amount times (B) the number of Purchase Contracts with respect to which the Holder has elected to effect Early Settlement. Upon

A–7

Early Settlement of Purchase Contracts by a Holder of the related Units, the Pledged Preferred Securities or the Pledged Treasury Consideration shall be released from the Pledge as provided in the Pledge Agreement and the Holder shall be entitled to receive a number of shares of Common Stock on account of each Purchase Contract forming part of a Normal Unit as to which Early Settlement is effected equal to the Early Settlement Rate. The Early Settlement Rate shall initially be equal to shares of Common Stock and shall be adjusted in the same manner and at the same time as the Settlement Rate is adjusted as provided in the Purchase Contract Agreement.

    Upon registration of transfer of this Normal Units Certificate, the transferee shall be bound (without the necessity of any other action on the part of such transferee, except as may be required by the Agent pursuant to the Purchase Contract Agreement), under the terms of the Purchase Contract Agreement and the Purchase Contracts evidenced hereby and the transferor shall be released from the obligations under the Purchase Contracts evidenced by this Normal Units Certificate. The Company covenants and agrees, and the Holder, by its acceptance hereof, likewise covenants and agrees, to be bound by the provisions of this paragraph.

    The Holder of this Normal Units Certificate, by its acceptance hereof, authorizes the Agent to enter into and perform the related Purchase Contracts forming part of the Normal Units evidenced hereby on his behalf as his attorney-in-fact, expressly withholds any consent to the assumption (i.e., affirmance) of the Purchase Contracts by the Company or its trustee in the event that the Company becomes the subject of a case under the Bankruptcy Code, agrees to be bound by the terms and provisions thereof, covenants and agrees to perform such Holder's obligations under such Purchase Contracts, consents to the provisions of the Purchase Contract Agreement, authorizes the Agent to enter into and perform the Pledge Agreement on such Holder's behalf as attorney-in-fact, and consents to the Pledge of the Preferred Securities or the appropriate Treasury Consideration, as the case may be, underlying this Normal Units Certificate pursuant to the Pledge Agreement. The Holder further covenants and agrees, that, to the extent and in the manner provided in the Purchase Contract Agreement and the Pledge Agreement, but subject to the terms thereof, payments in respect of the Pledged Preferred Securities or the Pledged Treasury Consideration, as the case may be, to be paid upon settlement of such Holder's obligations to purchase Common Stock under the Purchase Contract, shall be paid on the Stock Purchase Date by the Collateral Agent to the Company in satisfaction of such Holder's obligations under such Purchase Contract and such Holder shall acquire no right, title or interest in such payments.

    Each Holder of any Unit, and each Beneficial Owner thereof, by its acceptance thereof or of its interest therein, further agrees to treat (i) itself as the owner of the related Preferred Securities, Treasury Consideration or Treasury Securities, as the case may be, and (ii) the Senior Debentures as indebtedness of the Company, in each case, for United States federal, state and local income and franchise tax purposes.

    Subject to certain exceptions, the provisions of the Purchase Contract Agreement may be amended with the consent of the Holders of a majority of the Purchase Contracts.

    The Purchase Contracts shall for all purposes be governed by, and construed in accordance with, the laws of the State of New York, without regard to its principles of conflicts of laws.

    The Company, the Agent and its Affiliates and any agent of the Company or the Agent may treat the Person in whose name this Normal Units Certificate is registered as the owner of the Normal Units evidenced hereby for the purpose of receiving payments of distributions payable quarterly on the Preferred Securities or the Treasury Portfolio, as the case may be, performance of the Purchase Contracts and for all other purposes whatsoever, whether or not any payments in respect thereof be overdue and notwithstanding any notice to the contrary, and neither the Company, the Agent, such Affiliates nor any such agent shall be affected by notice to the contrary.

    The Purchase Contracts shall not, prior to the settlement thereof, entitle the Holder to any of the rights of a holder of shares of Common Stock.

    A copy of the Purchase Contract Agreement is available for inspection at the offices of the Agent.

(Reverse of Stripped Units Certificate)

    Each Purchase Contract evidenced hereby is governed by a Purchase Contract Agreement, dated as of December 5, 2001 (as may be supplemented from time to time, the "Purchase Contract Agreement"), between the Company and BNY Western Trust Company, as Purchase Contract Agent (including its successors thereunder, herein called the "Agent"), to which the Purchase Contract Agreement and supplemental agreements thereto reference is hereby made for a description of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Agent, the Company and the Holders and of the terms upon which the Stripped Units Certificates are, and are to be, executed and delivered.

    Each Purchase Contract evidenced hereby obligates the Holder of this Stripped Units Certificate to purchase, and the Company to sell, on the Stock Purchase Date at a price equal to the Stated Amount (the "Purchase Price"), a number of shares of Common Stock of the Company equal to the Settlement Rate, unless, on or prior to the Stock Purchase Date, there shall have occurred a Termination Event or an Early Settlement or Merger Early Settlement with respect to the Unit of which such Purchase Contract is a part. The "Settlement Rate" is equal to (a) if the Average Trading Price (as defined below) is greater than $38.88 (the "Threshold Appreciation Price"), 1.2860 shares of Common Stock per Purchase Contract, (b) if the Average Trading Price is less than the Threshold Appreciation Price but is greater than $31.87, the number of shares of Common Stock per Purchase Contract equal to the Stated Amount divided by the Average Trading Price and (c) if the Average Trading Price is less than $31.87, 1.5689 shares of Common Stock per Purchase Contract, in each case subject to adjustment as provided in the Purchase Contract Agreement. No fractional shares of Common Stock will be issued upon settlement of Purchase Contracts, as provided in the Purchase Contract Agreement.

    The "Average Trading Price" means the average of the Closing Prices per share of Common Stock on each of the 20 consecutive Trading Days ending on the third Trading Day immediately preceding the Stock Purchase Date.

    The "Closing Price" of the Common Stock on any date of determination means the closing sale price (or, if no closing price is reported, the last reported sale price) of the Common Stock on the New York Stock Exchange (the "NYSE") on such date or, if the Common Stock is not listed for trading on the NYSE on any such date, as reported in the composite transactions for the principal United States securities exchange on which the Common Stock is so listed, or if the Common Stock is not so listed on a United States national or regional securities exchange, as reported by The Nasdaq Stock Market, or, if the Common Stock is not so reported, the last quoted bid price for the Common Stock in the over-the-counter market as reported by the National Quotation Bureau or similar organization, or, if such bid price is not available, the market value of the Common Stock on such date as determined by a nationally recognized independent investment banking firm retained for this purpose by the Company.

    A "Trading Day" means a day on which the Common Stock (a) is not suspended from trading on any national or regional securities exchange or association or over-the-counter market at the close of business and (b) has traded at least once on the national or regional securities exchange or association or over-the-counter market that is the primary market for the trading of the Common Stock.

    Each Purchase Contract evidenced hereby may be settled prior to the Stock Purchase Date through Early Settlement or Merger Early Settlement, in accordance with the terms of the Purchase Contract Agreement.

    In accordance with the terms of the Purchase Contract Agreement, the Holder of this Stripped Units Certificate shall pay the Purchase Price for the shares of Common Stock purchased pursuant to each Purchase Contract evidenced hereby (i) by effecting an Early Settlement or Merger Early

B–4

Settlement or (ii) by application of payments received in respect of the Pledged Treasury Securities underlying the Stripped Units represented by this Stripped Units Certificate.

    The Company shall not be obligated to issue any shares of Common Stock in respect of a Purchase Contract or deliver any certificates therefor to the Holder unless it shall have received payment in full of the aggregate Purchase Price for the shares of Common Stock to be purchased thereunder in the manner herein set forth.

    The Stripped Units Certificates are issuable only in registered form and only in denominations of a single Stripped Unit and any integral multiple thereof. The transfer of any Stripped Units Certificate will be registered and Stripped Units Certificates may be exchanged as provided in the Purchase Contract Agreement. The Stripped Units Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents permitted by the Purchase Contract Agreement. No service charge shall be required for any such registration of transfer or exchange, but the Company and the Agent may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. The Holder of a Stripped Unit may substitute for the Pledged Treasury Securities securing its obligations under the related Purchase Contract Preferred Securities or the appropriate Treasury Consideration in accordance with the terms of the Purchase Contract Agreement and the Pledge Agreement. From and after such substitution, the Unit for which such Pledged Preferred Securities or Pledged Treasury Consideration secures the Holder's obligation under the Purchase Contract shall be referred to as a "Normal Unit." A Holder that elects to substitute Preferred Securities or the appropriate Treasury Consideration, as the case may be, for Pledged Treasury Securities, thereby reestablishing Normal Units, shall be responsible for any fees or expenses payable in connection therewith. Except as provided in the Purchase Contract Agreement, for so long as the Purchase Contract underlying a Stripped Unit remains in effect, such Stripped Unit shall not be separable into its constituent parts, and the rights and obligations of the Holder of such Stripped Unit in respect of the Pledged Treasury Security and the Purchase Contract constituting such Stripped Unit may be transferred and exchanged only as a Stripped Unit.

    The Purchase Contracts and all obligations and rights of the Company and the Holders thereunder, shall immediately and automatically terminate, without the necessity of any notice or action by any Holder, the Agent or the Company, if, on or prior to the Stock Purchase Date, a Termination Event shall have occurred. Upon the occurrence of a Termination Event, the Company shall promptly but in no event later than two Business Days thereafter give written notice to the Agent, the Collateral Agent and to the Holders, at their addresses as they appear in the Stripped Units Register. Upon and after the occurrence of a Termination Event, the Collateral Agent shall release the Pledged Treasury Securities from the Pledge in accordance with the provisions of the Pledge Agreement.

    Subject to and upon compliance with the provisions of the Purchase Contract Agreement, at the option of the Holder thereof, Purchase Contracts underlying Securities having an aggregate Stated Amount equal to $1,000 or an integral multiple thereof may be settled early ("Early Settlement") as provided in the Purchase Contract Agreement. In order to exercise the right to effect Early Settlement with respect to any Purchase Contracts evidenced by this Stripped Unit Certificate, the Holder of this Stripped Unit Certificate shall deliver this Stripped Unit Certificate to the Agent at the Corporate Trust Office duly endorsed for transfer to the Company or in blank with the form of Election to Settle Early set forth below duly completed and accompanied by payment in the form of immediately available funds payable to the order of the Company in an amount (the "Early Settlement Amount") equal to the product of (A) the Stated Amount times (B) the number of Purchase Contracts with respect to which the Holder has elected to effect Early Settlement. Upon Early Settlement of Purchase Contracts by a Holder of the related Units, the Pledged Treasury Consideration shall be released from the Pledge as provided in the Pledge Agreement and the Holder shall be entitled to receive, a number of shares of common Stock on account of each Purchase Contract forming part of a Stripped Unit as

    This Remarketing Agreement (this "Agreement") is being entered into pursuant to the Purchase Contract Agreement between the Company and BNY Western Trust Company, as purchase contract agent (the "Purchase Contract Agent"), dated as of December 5, 2001 (the "Purchase Contract Agreement"). The Debentures have been issued by the Company pursuant to Indenture, dated as of October 1, 1985, between the Company and U.S. Bank Trust National Association (as successor in interest to Morgan Guaranty Trust Company of New York), as trustee (the "Original Trustee") (the "Original Indenture"), as supplemented by the First Supplemental Indenture between the Company and the Original Trustee, dated as of December 20, 1989 (the "First Supplement"), the Second Supplemental Indenture between the Company and the Original Trustee, dated as of August 1, 1990 (the "Second Supplement"), and the Third Supplemental Indenture, dated as of December 5, 2001, among the Company, the Original Trustee and BNY Western Trust Company, as series trustee (the "Trustee") (the "Third Supplement," and, together with the Original Indenture, the First Supplement and the Second Supplement, the "Indenture").

    Each Debenture was issued by the Company to Boise Cascade I (the "Trust") to underlying preferred securities ("Preferred Securities") issued as part of an equity security unit (each, a "Unit") that initially also included a contract (a "Purchase Contract") under which the holder of the related Unit will purchase from the Company on December 26, 2004, a number of shares (the "Issuable Common Stock") of common stock, par value $2.50 per share, of the Company (the "Common Stock") equal to the Settlement Rate as set forth in the Purchase Contract Agreement. In connection with the liquidation of the Trust, the Debentures were issued to the holders of the Preferred Securities, and the Normal Units include Debentures in lieu of Preferred Securities. In accordance with the terms of the Purchase Contract Agreement, the Debentures constituting a part of the Units have been pledged by the Purchase Contract Agent, on behalf of the holders of the Units, to JPMorgan Chase Bank, as collateral agent, custodial agent and securities intermediary (the "Collateral Agent"), pursuant to the Pledge Agreement, dated as of December 5, 2001 (the "Pledge Agreement"), among the Company, the Purchase Contract Agent and the Collateral Agent to secure the holders' obligation to purchase the Issuable Common Stock under the Purchase Contracts.

*This form of Remarketing Agreement is to be used if the Preferred Securities have been redeemed in whole.

    The Remarketing (as defined below) of the Debentures is provided for in the Purchase Contract Agreement. As used in this Agreement, "Transaction Documents" shall mean, collectively, the Indenture, the Purchase Contract Agreement, the Declaration, the Pledge Agreement and this Agreement; the term "Remarketed Debentures" means the Debentures subject to the Remarketing as notified to the Remarketing Agent by the Purchase Contract Agent and the Custodial Agent, on or prior to the first Business Day prior to a Remarketing Date; the term "Remarketing Procedures" means the procedures in connection with the Remarketing of the Debentures, as described herein and in the Purchase Contract Agreement and the Pledge Agreement; the term "Remarketing" means the remarketing of the Remarketed Debentures pursuant to the Remarketing Procedures; the term "Remarketing Date" means the third Business Day immediately preceding September 16, 2004; and the term "Instruments" means the Remarketed Debentures, the Purchase Contracts, the Units, the Preferred Securities, the Debentures and the Issuable Common Stock.

In this case, the Remarketing Agent shall so advise by telephone the Depositary, the Purchase Contract Agent Trustee, the Company, the Trust and the Collateral Agent. On the third Business Day following the Last Failed Remarketing, the Remarketing Agent shall remit (i) to the Custodial Agent the Remarketed Debentures comprised of the Separate Debentures and (ii) to the Collateral Agent the balance of the Remarketed Debentures.

    (ii) The unissued Shares to be issued and sold by the Company pursuant to the Purchase Contracts and the Purchase Contract Agreement have been duly authorized and reserved for issuance and, when issued and delivered against payment therefor as provided in the Purchase Contracts and the Purchase Contract Agreement, will be duly and validly issued, fully paid and non-assessable and the outstanding shares of Common Stock conform in all material respects to the description thereof contained in the Prospectus and Remarketing Materials; and the stockholders of the Company have no preemptive rights with respect to the Securities or the shares of Common Stock issuable upon settlement of the Purchase Contracts; it being understood that such counsel need express no opinion or belief as to the validity of the common stock purchase rights distributed by the Company to its shareholders on September 25, 1998;

    (iii) This Agreement has been duly authorized, executed and delivered by the Company;

    (iv) The Purchase Contract Agreement, the Purchase Contracts underlying the Units and the Pledge Agreement have each been duly authorized, executed and delivered by the Company and, assuming due authorization, execution and delivery by the other parties thereto, constitute a valid and legally binding agreement of the Company (and together they create, to the extent provided therein, a valid interest of the holders of the Securities in the Preferred Securities) enforceable against the Company in accordance with its terms, subject, as to enforcement, to bankruptcy, insolvency, reorganization, fraudulent transfer, fraudulent conveyance, moratorium and similar laws of general applicability relating to or affecting creditors' rights and to general equity principles (whether such principles are considered in a proceeding in equity or in law), the Pledge Agreement creates, as collateral security for the performance when due by the holders from time to time of the Securities of their respective obligations under the Purchase Contracts constituting part of such Securities, a legal, valid and perfected security interest (as that term is defined in the Uniform Commercial Code, as adopted and in effect in the State of New York), in favor of the

9

Collateral Agent, in the right, title and interest of such holders in the Pledged Securities (as defined in the Pledge Agreement) constituting a part of such Securities;

    (v) The Declaration, the Indenture and the Debentures, each have been duly authorized and constitute a valid and legally binding instrument, enforceable against the Company in accordance with its terms, subject, as to enforcement, to bankruptcy, insolvency, reorganization, fraudulent transfer, fraudulent conveyance, moratorium and similar laws of general applicability relating to or affecting creditors' rights and to general equity principles (whether such principles are considered in a proceeding in equity or in law); the Indenture has been duly qualified under the Trust Indenture Act; and the Senior Debentures are entitled to the benefits of the Indenture;

    (vi) The Registration Statement has become effective under the Act, and, to the best of the knowledge of such counsel, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or are pending or contemplated by the Commission;

   (vii) When each part of the Registration Statement became effective, such part, the Prospectus and the Remarketing Materials included therein complied as to form in all material respects with the requirements of the Act and the Rules and Regulations, and while such counsel has not independently verified the accuracy, completeness or fairness of such statements and takes no responsibility therefor, such counsel has no reason to believe that such documents contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary to make the statements therein not misleading; and on the date hereof and at Remarketing, the Registration Statement, the Prospectus and the Remarketing Materials as then amended or supplemented complied or complies, as the case may be, as to form in all material respects with the requirements of the Act and the Rules and Regulations and while such counsel has not independently verified the accuracy, completeness or fairness of such statements and takes no responsibility therefor, such counsel has no reason to believe that such documents contained or contain, as the case may be, any untrue statement of a material fact or omitted or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading; it being understood that such counsel need express no opinion or belief as to the financial statements or financial data contained in the Registration Statement, the Prospectus or the Remarketing Materials or any such amendment or supplement; and

   (viii) The discussion set forth in the Prospectus under the heading "U.S. Federal Income Tax Consequences", insofar as it relates to matters of United States federal income tax law, is accurate in all material respects; provided that such counsel need express no opinion as to statements in such discussion concerning the Company's expectations or determinations.

    In rendering such opinion, such counsel may state that he expresses no opinion as to the laws of any jurisdiction other than the United States and the State of Delaware and such counsel may rely as to all matters governed by the laws of the State of New York upon the opinion of [                            ] referred to in Section 5(c).

    (e) John W. Holleran, Senior Vice-President and General Counsel of the Company, shall have furnished to you his written opinion, dated the Remarketing Date, in form and substance reasonably satisfactory to the Remarketing Agent, to the effect that:

     (i) Each document incorporated by reference in the Registration Statement, Prospectus or Remarketing Materials or any amendment or supplement thereto, at the time such document was filed or became effective under the Act, as the case may be, complied as to form in all material respects with the requirements of the Exchange Act and the rules and regulations of the Commission thereunder;

10

    (ii) The Units, the Purchase Contract Agreement, the Purchase Contracts, the Indenture, the Senior Debentures and the Pledge Agreement conform in all material respects to the descriptions thereof contained in the Prospectus and the Remarketing Materials;

    (iii) The descriptions in the Registration Statement, Prospectus and the Remarketing Materials of statutes, legal and governmental proceedings and contracts and other documents are accurate and fairly present the information required to be shown and such counsel does not know of any legal or governmental proceedings required to be described in the Prospectus which are not described as required in all material respects, nor of any contract or documents of a character required to be described in the Registration Statement, Prospectus or Remarketing Materials which are not described as required in all material respects; and

    (iv) No holders of securities of the Company have rights to the registration of such securities under the Registration Statement.

    In rendering such opinion, such counsel may state that they express no opinion as to the laws of any jurisdiction other than the United States and the State of Delaware and such counsel may rely as to all matters governed by the laws of the State of New York upon the opinion of [                            ] referred to in Section 5(c).

    (f)  The Company will furnish the Remarketing Agent with such conformed copies of such opinions, certificates, letters and documents as the Remarketing Agent reasonably requests.

    (g) On the Remarketing Date at 9:30 a.m., New York City time Arthur Andersen LLP, the independent auditors, or another independent accounting firm with a nationally recognized reputation, that have audited the consolidated financial statements of the Company, shall have furnished to the Remarketing Agent a letter or letters, dated the respective dates of delivery thereof, in form and substance reasonably satisfactory to the Remarketing Agent, containing statements and information of the type ordinarily included in accountants' "comfort letters" with respect to certain financial information contained in the Prospectus and in the Remarketing Materials.

    (h) (i) Neither the Company nor any of its subsidiaries shall have sustained since the date of the latest audited financial statements included or incorporated by reference in the Prospectus and the Remarketing Materials 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 and the Remarketing Materials, and (ii) since the respective dates as of which information is given in the Prospectus and the Remarketing Materials there shall not have been any change in the capital stock 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 and the Remarketing Materials, 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 the Securities being issued at such Remarketing Date on the terms and in the manner contemplated in the Prospectus and the Remarketing Materials;

    (i)  On or after the date hereof (i) no downgrading shall have occurred in the rating accorded the Company's debt securities or preferred stock 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 (ii) 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 preferred stock;

11

    (j)  On or after the date hereof, there shall not have occurred any of the following: (i) a change in U.S. or international financial, political or economic conditions or currency exchange rates or exchange controls as would, in the judgment of the Remarketing Agent, be likely to prejudice materially the success of the proposed issue, sale or distribution of the Debentures whether in the primary market or in respect of dealings in the secondary market; (ii) a suspension or material limitation in trading in securities generally on the Exchange; (iii) a suspension or material limitation in trading in the Company's securities on the Exchange; (iv) a general moratorium on commercial banking activities declared by either Federal or New York State authorities or a material disruption in commercial banking or securities settlement or material disruption in commercial banking or securities settlement or clearance services in the United States; (v) the outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency or war; or (vi) the occurrence of any other calamity or crisis or any change in financial, political or economic conditions in the United States or elsewhere, if the effect of any such event specified in clause (v) or (vi) in the judgment of the Remarketing Agent makes it impracticable or inadvisable to proceed with the Remarketing on the terms and in the manner contemplated in the Prospectus and Remarketing Materials;

    (k) The Company shall have complied with the provisions of Section 4(c) hereof with respect to the furnishing of copies of the Prospectus and the Remarketing Materials on the New York Business Day next succeeding the date of this Agreement;

    (l)  The Company shall have furnished or caused to be furnished to the Remarketing Agent at the Remarketing Date certificates of officers of the Company satisfactory to the Remarketing Agent as to the accuracy of the representations and warranties of the Company herein at and as of the Remarketing, as to the performance by the Company, of all of its obligations hereunder to be performed at or prior to the Remarketing, as to the matters set forth in subsections (a) and (j) of this Section 5 and as to such other matters as you may reasonably request.

    (m) The Remarketing Agent shall have received assurances reasonably satisfactory to it from each "plan," as such term is defined under the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), participating in the remarketing program to the effect that such participation will not constitute a prohibited transaction under ERISA or Section 4975 of the Internal Revenue Code of 1986, as amended, or other similar laws, for which an exemption is not available.

    All opinions, letters, evidence and certificates mentioned above or elsewhere in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in form and substance reasonably satisfactory to the Remarketing Agent.

    SECTION 6.  Indemnification and Contribution.

    (a) The Company will indemnify and hold harmless the Remarketing Agent against any losses, claims, damages or liabilities, joint or several, to which the Remarketing Agent may become subject, under the Securities 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 any Preliminary Prospectus, [the Registration Statement,] the Prospectus or the Remarketing Materials, 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, and will reimburse the Remarketing Agent for any legal or other expenses reasonably incurred by the Remarketing Agent 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

12

any Preliminary Prospectus, [the Registration Statement,] the Prospectus or the Remarketing Materials, or any such amendment or supplement(s) in reliance upon and in conformity with written information furnished to the Company by the Remarketing Agent expressly for use therein.

    (b) The Remarketing Agent will indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Securities 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 any Preliminary Prospectus, [the Registration Statement,] the Prospectus or the Remarketing Materials 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 any Preliminary Prospectus, [the Registration Statement,] the Prospectus or the Remarketing Materials or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company by the Remarketing Materials 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) or (b) 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 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 a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

    (d) If the indemnification provided for in this Section 6 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) 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 Remarketing Agent on the other from the Remarketing. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the

13

indemnified party failed to give the notice required under subsection (c) 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 on the one hand and the Remarketing Agent 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 the Remarketing Agent on the other shall be deemed to be in the same proportion as the aggregate principal amount of the Remarketed Debentures bears to the remarketing fees received by the Remarketing Agent under this Agreement. 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 the Remarketing Agent 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 Remarketing Agent agree that it would not be just and equitable if contributions pursuant to this subsection (d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d). 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 (d) 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 (d), the Remarketing Agent shall not be required to contribute any amount in excess of the amount by which the aggregate principal amount of the Remarketed Debentures exceeds the amount of any damages which the Remarketing Agent has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

    (e) The obligations of the Company under this Section 6 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 the Remarketing Agent within the meaning of the Securities Act. The obligations of the Remarketing Agent under this Section 6 shall be in addition to any liability which the Remarketing Agent 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 Securities Act.

    SECTION 7.  Resignation and Removal of the Remarketing Agent.  The Remarketing Agent may resign and be discharged from its duties and obligations hereunder, and the Company may remove the Remarketing Agent, by giving 60 days prior written notice to the Purchase Contract Agent, the Property Trustee and the Indenture Trustee and, in the case of a removal, the removed Remarketing Agent; provided that no such resignation nor any such removal shall become effective until the Company shall have appointed at least one nationally recognized broker-dealer as successor Remarketing Agent and such successor Remarketing Agent shall have entered into a remarketing agreement with the Company in which it shall have agreed to conduct the Remarketing in accordance with the Remarketing Procedures. In any such case, the Company will use its best reasonable efforts to appoint a successor Remarketing Agent and enter into such a remarketing agreement with such person as soon as reasonably practicable. The provisions of Sections 4 and 6 shall survive the resignation or removal of any Remarketing Agent pursuant to this Agreement.

    SECTION 8.  Dealing in the Remarketed Debentures.  The Remarketing Agent, when acting as a Remarketing Agent or in its individual or any other capacity, may, to the extent permitted by law, buy,

14

sell, hold and deal in any of the Remarketed Debentures. The Remarketing Agent may exercise any vote or join in any action which any beneficial owner of Remarketed Debentures may be entitled to exercise or take pursuant to the Indenture or the Indenture with like effect as if it did not act in any capacity hereunder. The Remarketing Agent, in its individual capacity, either as principal or agent, may also engage in or have an interest in any financial or other transaction with the Company, as freely as if it did not act in any capacity hereunder.

    SECTION 9.  Remarketing Agent's Performance; Duty of Care; Supervising Obligations.  The duties and obligations of the Remarketing Agent shall be determined solely by the express provisions of this Agreement and the Purchase Contract Agreement. No implied covenants or obligations of or against the Remarketing Agent shall be read into this Agreement or the Purchase Contract Agreement. In the absence of bad faith on the part of the Remarketing Agent, the Remarketing Agent may conclusively rely upon any document furnished to it, which purports to conform to the requirements of this Agreement or the Purchase Contract Agreement as to the truth of the statements expressed in any of such documents. The Remarketing Agent shall be protected in acting upon any document or communication reasonably believed by it to have been signed, presented or made by the proper party or parties. The Remarketing Agent, acting under this Agreement, shall incur no liability to the Company or to any holder of Remarketed Debentures in its individual capacity or as Remarketing Agent for any action or failure to act, on its part in connection with a Remarketing or otherwise, except if such liability is judicially determined to have resulted from the bad faith, negligence or willful misconduct on its part. The Remarketing Agent may, but shall not be obligated to, purchase Remarketed Debentures for its own account.

    If at any time during the term of this Agreement, any event of default under the Indenture or any event that with the passage of time or the giving of notice or both would become an event of default under the Indenture has occurred and is continuing under the Indenture, then the obligations and duties of the Remarketing Agent under this Agreement shall be suspended until such default or event has been cured. The Company will cause the Indenture Trustee and the Purchase Contract Agent to give the Remarketing Agent notice of all such defaults and events of which such trustee or agent is aware.

    SECTION 10.  Termination.  This Agreement shall terminate as to the Remarketing Agent on the effective date of the resignation or removal of the Remarketing Agent pursuant to Section 7. In addition, the obligations of the Remarketing Agent hereunder may be terminated by it by notice given to the Company prior to 10:00 A.M., New York City time, on the Remarketing Date if, prior to that time, any of the events described in Sections 5(g), (h) or (i) shall have occurred.

    SECTION 11.  Notices.  Except as otherwise stated herein, all statements, requests, notices and agreements hereunder shall be in writing, and if to the Remarketing Agent shall be delivered or sent by mail or facsimile transmission to                            ; if to the Company shall be delivered or sent by mail to 1111 West Jefferson Street, P.O. Box 50, Boise, Idaho, 83728-0001 or by facsimile transmission to (208) 384-4912, Attention: General Counsel; if to the Trust shall be delivered or sent by mail to c/o Boise Cascade Corporation, 1111 West Jefferson Street, P.O. Box 50, Boise, Idaho, 83728-0001, or by facsimile transmission to (208) 384-4912, Attention: General Counsel, with a copy sent to the Company; if to the Property Trustee shall be delivered or sent by mail to BNY Western Trust Company, 601 Union Street, Suite 1720, Seattle, Washington, 98101, Attention: Corporate Trust; if to the Indenture Trustee shall be sent by mail to BNY Western Trust Company, 601 Union Street, Suite 1720, Seattle, Washington, 98101, Attention: Corporate Trust; if to the Purchase Contract Agent shall be delivered or sent by mail to BNY Western Trust Company, 601 Union Street, Suite 1720, Seattle, Washington, 98101, Attention: Corporate Trust; and if to the Collateral Agent or the Custodial Agent shall be delivered or sent by mail to JPMorgan Chase Bank, 450 West 33rd Street, New York, New York 10001, Attention: Institutional Trust Services.

15

    Any such statements, requests, notices or agreements shall take effect at the time of receipt thereof.

    SECTION 12.  Successors and Assigns.  This Agreement shall be binding upon, and inure solely to the benefit of, the Remarketing Agent, the Company to the extent provided in Section 6 hereof, the officers and directors of the Company, each person who controls the Company or the Remarketing Agent, 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.

The Debentures have been issued by the Company pursuant to Indenture, dated as of October 1, 1985, between the Company and U.S. Bank Trust National Association (as successor in interest to Morgan Guaranty Trust Company of New York), as trustee (the "Original Trustee") (the "Original Indenture"), as supplemented by the First Supplemental Indenture between the Company and the Original Trustee, dated as of December 20, 1989 (the "First Supplement"), the Second Supplemental Indenture between the Company and the Original Trustee, dated as of August 1, 1990 (the "Second Supplement"), and the Third Supplemental Indenture, dated as of December 5, 2001, among the Company, the Original Trustee and BNY Western

    (c) [                            ], counsel for the Remarketing Agent, shall have furnished to the Remarketing Agent such written opinion or opinions, dated the Remarketing Date, with respect to the incorporation of the Company, the validity of the Debentures, the Issuable Common Stock, the Guarantee, [the Registration Statement,] Prospectus, the Remarketing Materials and such other related matters as the Remarketing Agent may reasonably request, and such counsel shall have received such papers and information as they may reasonably request to enable them to pass upon such matters.

    (d) Bell, Boyd & Lloyd LLC, counsel for the Company, shall have furnished to the Remarketing Agent their written opinion, dated the Remarketing Date, in form and substance reasonably satisfactory to Remarketing Agent, to the effect that:

     (i) The Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of the State of Delaware, with corporate power and authority under such laws to own its properties and conduct its business as described in the Prospectus and the Remarketing Materials;

    (ii) The unissued Shares to be issued and sold by the Company pursuant to the Purchase Contracts and the Purchase Contract Agreement have been duly authorized and reserved for issuance and, when issued and delivered against payment therefor as provided in the Purchase Contracts and the Purchase Contract Agreement, will be duly and validly issued, fully paid and non-assessable and the outstanding shares of Common Stock conform in all material respects to the description thereof contained in the Prospectus and Remarketing Materials; and the stockholders of the Company have no preemptive rights with respect to the Securities or the shares of Common Stock issuable upon settlement of the Purchase Contracts; it being understood that such counsel need express no opinion or belief as to the validity of the common stock purchase rights distributed by the Company to its shareholders on September 25, 1998;

    (iii) This Agreement has been duly authorized, executed and delivered by the Company and the Trust;

    (iv) The Purchase Contract Agreement, the Purchase Contracts underlying the Units and the Pledge Agreement have each been duly authorized, executed and delivered by the Company and, assuming due authorization, execution and delivery by the other parties thereto, constitute a valid and legally binding agreement of the Company (and together they create, to the extent provided therein, a valid interest of the holders of the Securities in the Preferred Securities) enforceable against the Company in accordance with its terms, subject, as to enforcement, to bankruptcy, insolvency, reorganization, fraudulent transfer, fraudulent conveyance, moratorium and similar laws of general applicability relating to or affecting creditors' rights and to general equity principles (whether such principles are considered in a proceeding in equity or in law), the Pledge Agreement creates, as collateral security for the performance when due by the holders from time to time of the Securities of their respective obligations under the Purchase Contracts constituting

10

part of such Securities, a legal, valid and perfected security interest (as that term is defined in the Uniform Commercial Code, as adopted and in effect in the State of New York), in favor of the Collateral Agent, in the right, title and interest of such holders in the Pledged Securities (as defined in the Pledge Agreement) constituting a part of such Securities;

    (v) The Guarantee Agreement, the Declaration, the Indenture and the Debentures, each have been duly authorized and constitute a valid and legally binding instrument, enforceable against the Company in accordance with its terms, subject, as to enforcement, to bankruptcy, insolvency, reorganization, fraudulent transfer, fraudulent conveyance, moratorium and similar laws of general applicability relating to or affecting creditors' rights and to general equity principles (whether such principles are considered in a proceeding in equity or in law); the Declaration, the Indenture and the Guarantee Agreement have been duly qualified under the Trust Indenture Act; and the Debentures are entitled to the benefits of the Indenture;

    (vi) The Registration Statement has become effective under the Act, and, to the best of the knowledge of such counsel, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or are pending or contemplated by the Commission;

   (vii) When each part of the Registration Statement became effective, such part, the Prospectus and the Remarketing Materials included therein complied as to form in all material respects with the requirements of the Act and the Rules and Regulations, and while such counsel has not independently verified the accuracy, completeness or fairness of such statements and takes no responsibility therefor, such counsel has no reason to believe that such documents contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary to make the statements therein not misleading; and on the date hereof and at Remarketing, the Registration Statement, the Prospectus and the Remarketing Materials as then amended or supplemented complied or complies, as the case may be, as to form in all material respects with the requirements of the Act and the Rules and Regulations and while such counsel has not independently verified the accuracy, completeness or fairness of such statements and takes no responsibility therefor, such counsel has no reason to believe that such documents contained or contain, as the case may be, any untrue statement of a material fact or omitted or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading; it being understood that such counsel need express no opinion or belief as to the financial statements or financial data contained in the Registration Statement, the Prospectus or the Remarketing Materials or any such amendment or supplement; and

   (viii) The discussion set forth in the Prospectus under the heading "U.S. Federal Income Tax Consequences", insofar as it relates to matters of United States federal income tax law, is accurate in all material respects; provided that such counsel need express no opinion as to statements in such discussion concerning the Company's expectations or determinations.

    In rendering such opinion, such counsel may state that he expresses no opinion as to the laws of any jurisdiction other than the United States and the State of Delaware and such counsel may rely as to all matters governed by the laws of the State of New York upon the opinion of [            ] referred to in Section 5(c).

    (e) John W. Holleran, Senior Vice-President and General Counsel of the Company, shall have furnished to you his written opinion, dated the Remarketing Date, in form and substance reasonably satisfactory to the Remarketing Agent, to the effect that:

     (i) Each document incorporated by reference in the Registration Statement, Prospectus or Remarketing Materials or any amendment or supplement thereto, at the time such document was filed or became effective under the Act, as the case may be, complied as to form in all material

11

respects with the requirements of the Exchange Act and the rules and regulations of the Commission thereunder;

    (ii) The Units, the Purchase Contract Agreement, the Purchase Contracts, the Declaration, the Preferred Securities, the Indenture, the Debentures, the Guarantee Agreement, the Guarantee and the Pledge Agreement conform in all material respects to the descriptions thereof contained in the Prospectus and the Remarketing Materials;

    (iii) The descriptions in the Registration Statement, Prospectus and the Remarketing Materials of statutes, legal and governmental proceedings and contracts and other documents are accurate and fairly present the information required to be shown and such counsel does not know of any legal or governmental proceedings required to be described in the Prospectus which are not described as required in all material respects, nor of any contract or documents of a character required to be described in the Registration Statement, Prospectus or Remarketing Materials which are not described as required in all material respects; and

    (iv) No holders of securities of the Company have rights to the registration of such securities under the Registration Statement.

    In rendering such opinion, such counsel may state that they express no opinion as to the laws of any jurisdiction other than the United States and the State of Delaware and such counsel may rely as to all matters governed by the laws of the State of New York upon the opinion of [                            ] referred to in Section 5(c).

    (f)  Counsel to the Trust shall have furnished to the Remarketing Agent a written opinion in form and substance equivalent to the opinion delivered by counsel to the Trust pursuant to the Underwriting Agreement.

    (g) The Company and the Trust will furnish the Remarketing Agent with such conformed copies of such opinions, certificates, letters and documents as the Remarketing Agent reasonably requests.

    (h) On the Remarketing Date at 9:30 a.m., New York City time Arthur Andersen LLP, the independent auditors, or another independent accounting firm with a nationally recognized reputation, that have audited the consolidated financial statements of the Company, shall have furnished to the Remarketing Agent a letter or letters, dated the respective dates of delivery thereof, in form and substance reasonably satisfactory to the Remarketing Agent, containing statements and information of the type ordinarily included in accountants' "comfort letters" with respect to certain financial information contained in the Prospectus and in the Remarketing Materials.

    (i)  (i) Neither the Company nor any of its subsidiaries shall have sustained since the date of the latest audited financial statements included or incorporated by reference in the Prospectus and the Remarketing Materials 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 and the Remarketing Materials, and (ii) since the respective dates as of which information is given in the Prospectus and the Remarketing Materials there shall not have been any change in the capital stock 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 and the Remarketing Materials, 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

12

with the public offering or the delivery of the Securities being issued at such Remarketing Date on the terms and in the manner contemplated in the Prospectus and the Remarketing Materials;

    (j)  On or after the date hereof (i) no downgrading shall have occurred in the rating accorded the Company's debt securities or preferred stock 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 (ii) 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 preferred stock;

    (k) On or after the date hereof, there shall not have occurred any of the following: (i) a change in U.S. or international financial, political or economic conditions or currency exchange rates or exchange controls as would, in the judgment of the Remarketing Agent, be likely to prejudice materially the success of the proposed issue, sale or distribution of the Preferred Securities whether in the primary market or in respect of dealings in the secondary market; (ii) a suspension or material limitation in trading in securities generally on the Exchange; (iii) a suspension or material limitation in trading in the Company's securities on the Exchange; (iv) a general moratorium on commercial banking activities declared by either Federal or New York State authorities or a material disruption in commercial banking or securities settlement or material disruption in commercial banking or securities settlement or clearance services in the United States; (v) the outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency or war; or (vi) the occurrence of any other calamity or crisis or any change in financial, political or economic conditions in the United States or elsewhere, if the effect of any such event specified in clause (v) or (vi) in the judgment of the Remarketing Agent makes it impracticable or inadvisable to proceed with the Remarketing on the terms and in the manner contemplated in the Prospectus and Remarketing Materials;

    (l)  The Company and the Trust shall have complied with the provisions of Section 4(c) hereof with respect to the furnishing of copies of the Prospectus and the Remarketing Materials on the New York Business Day next succeeding the date of this Agreement;

    (m) The Company shall have furnished or caused to be furnished to the Remarketing Agent at the Remarketing Date certificates of officers of the Company satisfactory to the Remarketing Agent as to the accuracy of the representations and warranties of the Company and the Trust herein at and as of the Remarketing, as to the performance by the Company and the Trust, as the case may be, of all of their respective obligations hereunder to be performed at or prior to the Remarketing, as to the matters set forth in subsections (a) and (i) of this Section 5 and as to such other matters as you may reasonably request.

    (n) The Remarketing Agent shall have received assurances reasonably satisfactory to it from each "plan," as such term is defined under the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), participating in the remarketing program to the effect that such participation will not constitute a prohibited transaction under ERISA or Section 4975 of the Internal Revenue Code of 1986, as amended, or other similar laws, for which an exemption is not available.

    (o) The Trust shall have furnished or caused to be furnished to the Remarketing Agent at the Remarketing Date certificates of the Administrative Trustees of the Trust satisfactory to the Remarketing Agent as to the accuracy of the representations and warranties of the Trust herein at and as of the Remarketing, as to the performance by the Company and the Trust, as the case may be, of all its obligations hereunder to be performed at or prior to the Remarketing, as to the matters set forth in subsections (a) and (l) of this Section 5 and as to such other matters as you may reasonably request.

13

    All opinions, letters, evidence and certificates mentioned above or elsewhere in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in form and substance reasonably satisfactory to the Remarketing Agent.

    SECTION 6.  Indemnification and Contribution.  (a) The Company and the Trust will, jointly and severally, indemnify and hold harmless the Remarketing Agent against any losses, claims, damages or liabilities, joint or several, to which the Remarketing Agent may become subject, under the Securities 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 any Preliminary Prospectus, [the Registration Statement,] the Prospectus or the Remarketing Materials, 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, and will reimburse the Remarketing Agent for any legal or other expenses reasonably incurred by the Remarketing Agent in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company and the Trust 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 any Preliminary Prospectus, [the Registration Statement,] the Prospectus or the Remarketing Materials, or any such amendment or supplement(s) in reliance upon and in conformity with written information furnished to the Company by the Remarketing Agent expressly for use therein.

    (b) The Remarketing Agent will indemnify and hold harmless the Company and the Trust against any losses, claims, damages or liabilities to which the Company or the Trust may become subject, under the Securities 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 any Preliminary Prospectus, [the Registration Statement,] the Prospectus or the Remarketing Materials 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 any Preliminary Prospectus, [the Registration Statement,] the Prospectus or the Remarketing Materials or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company by the Remarketing Materials expressly for use therein; and will reimburse the Company and the Trust for any legal or other expenses reasonably incurred by the Company and the Trust 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) or (b) 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,

14

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 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 a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

    (d) If the indemnification provided for in this Section 6 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) 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 and the Trust on the one hand and the Remarketing Agent on the other from the Remarketing. 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 (c) 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 and the Trust on the one hand and the Remarketing Agent 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 and the Trust on the one hand and the Remarketing Agent on the other shall be deemed to be in the same proportion as the aggregate principal amount of the Remarketed Preferred Securities bears to the remarketing fees received by the Remarketing Agent under this Agreement. 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 and the Trust on the one hand or the Remarketing Agent on the other and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Trust and the Remarketing Agent agree that it would not be just and equitable if contributions pursuant to this subsection (d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d). 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 (d) 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 (d), the Remarketing Agent shall not be required to contribute any amount in excess of the amount by which the aggregate principal amount of the Remarketed Preferred Securities exceeds the amount of any damages which the Remarketing Agent has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

15

    (e) The obligations of the Company and the Trust under this Section 6 shall be in addition to any liability which the Company and the Trust may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls the Remarketing Agent within the meaning of the Securities Act. The obligations of the Remarketing Agent under this Section 6 shall be in addition to any liability which the Remarketing Agent may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company, each Administrative Trustee of the Trust and to each person, if any, who controls the Company and the Trust within the meaning of the Securities Act.

    SECTION 7.  Resignation and Removal of the Remarketing Agent.  The Remarketing Agent may resign and be discharged from its duties and obligations hereunder, and the Company may remove the Remarketing Agent, by giving 60 days prior written notice to the Purchase Contract Agent, the Property Trustee and the Trustee and, in the case of a removal, the removed Remarketing Agent; provided that no such resignation nor any such removal shall become effective until the Company shall have appointed at least one nationally recognized broker-dealer as successor Remarketing Agent and such successor Remarketing Agent shall have entered into a remarketing agreement with the Company and the Trust in which it shall have agreed to conduct the Remarketing in accordance with the Remarketing Procedures. In any such case, the Company will use its best reasonable efforts to appoint a successor Remarketing Agent and enter into such a remarketing agreement with such person as soon as reasonably practicable. The provisions of Sections 4 and 6 shall survive the resignation or removal of any Remarketing Agent pursuant to this Agreement.

    SECTION 8.  Dealing in the Remarketed Preferred Securities.  The Remarketing Agent, when acting as a Remarketing Agent or in its individual or any other capacity, may, to the extent permitted by law, buy, sell, hold and deal in any of the Remarketed Preferred Securities. The Remarketing Agent may exercise any vote or join in any action which any beneficial owner of Remarketed Preferred Securities may be entitled to exercise or take pursuant to the Purchase Contract Agreement or the Indenture with like effect as if it did not act in any capacity hereunder. The Remarketing Agent, in its individual capacity, either as principal or agent, may also engage in or have an interest in any financial or other transaction with the Trust, as freely as if it did not act in any capacity hereunder.

    SECTION 9.  Remarketing Agent's Performance; Duty of Care; Supervising Obligations.  The duties and obligations of the Remarketing Agent shall be determined solely by the express provisions of this Agreement and the Purchase Contract Agreement. No implied covenants or obligations of or against the Remarketing Agent shall be read into this Agreement or the Purchase Contract Agreement. In the absence of bad faith on the part of the Remarketing Agent, the Remarketing Agent may conclusively rely upon any document furnished to it, which purports to conform to the requirements of this Agreement or the Purchase Contract Agreement as to the truth of the statements expressed in any of such documents. The Remarketing Agent shall be protected in acting upon any document or communication reasonably believed by it to have been signed, presented or made by the proper party or parties. The Remarketing Agent, acting under this Agreement, shall incur no liability to the Company, the Trust or to any holder of Remarketed Preferred Securities in its individual capacity or as Remarketing Agent for any action or failure to act, on its part in connection with a Remarketing or otherwise, except if such liability is judicially determined to have resulted from the bad faith, negligence or willful misconduct on its part. The Remarketing Agent may, but shall not be obligated to, purchase Remarketed Preferred Securities for its own account.

    If at any time during the term of this Agreement, any event of default under the Indenture, Declaration or the Guarantee or any event that with the passage of time or the giving of notice or both would become an event of default under the Indenture, the Declaration or the Guarantee has occurred and is continuing under the Indenture, the Declaration or the Guarantee, as the case may be, then the obligations and duties of the Remarketing Agent under this Agreement shall be suspended until such default or event has been cured. The Company will cause the Trustee, the Property Trustee and the

16

Guarantee Trustee and the Purchase Contract Agent to give the Remarketing Agent notice of all such defaults and events of which such trustee or agent is aware.

    SECTION 10.  Termination.  This Agreement shall terminate as to the Remarketing Agent on the effective date of the resignation or removal of the Remarketing Agent pursuant to Section 7. In addition, the obligations of the Remarketing Agent hereunder may be terminated by it by notice given to the Company prior to 10:00 A.M., New York City time, on the Remarketing Date if, prior to that time, any of the events described in Sections 5(h), (i) or (j) shall have occurred.

    SECTION 11.  Notices.  Except as otherwise stated herein, all statements, requests, notices and agreements hereunder shall be in writing, and if to the Remarketing Agent shall be delivered or sent by mail or facsimile transmission to            ; if to the Company shall be delivered or sent by mail to 1111 West Jefferson Street, P.O. Box 50, Boise, Idaho, 83728-0001 or by facsimile transmission to (208) 384-4912, Attention:General Counsel; if to the Trust shall be delivered or sent by mail to c/o Boise Cascade Corporation, 1111 West Jefferson Street, P.O. Box 50, Boise, Idaho, 83728-0001, or by facsimile transmission to (208) 384-4912, Attention: General Counsel, with a copy sent to the Company; if to the Property Trustee shall be delivered or sent by mail to BNY Western Trust Company, 601 Union Street, Suite 1720, Seattle, Washington, 98101, Attention: Corporate Trust; if to the Indenture Trustee shall be sent by mail to BNY Western Trust Company, 601 Union Street, Suite 1720, Seattle, Washington, 98101, Attention:Corporate Trust; if to the Purchase Contract Agent shall be delivered or sent by mail to BNY Western Trust Company, 601 Union Street, Suite 1720, Seattle, Washington, 98101, Attention: Corporate Trust; and if to the Collateral Agent or the Custodial Agent shall be delivered or sent by mail to JPMorgan Chase Bank, 450 West 33rd Street, New York, New York 10001, Attention: Institutional Trust Services.

    Any such statements, requests, notices or agreements shall take effect at the time of receipt thereof.

    SECTION 12.  Successors and Assigns.  This Agreement shall be binding upon, and inure solely to the benefit of, the Remarketing Agent, the Company and the Trust to the extent provided in Section 6 hereof, the officers and directors of the Company, the trustees of the Trust and each person who controls the Company, the Trust or the Remarketing Agent, 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. No purchaser of any of the Preferred Securities from the Remarketing Agent shall be deemed a successor or assign by reason merely of such purchase.

    SECTION 13.  Governing Law.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW.

    SECTION 14.  Jurisdiction.  The Company and the Trust hereby submit to the nonexclusive jurisdiction of the Federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

    SECTION 15.  Counterparts.  This Agreement may be executed in one or more separate counterparts and, if executed in more than one counterpart, the executed counterparts shall each be deemed to be an original but all such counterparts shall together constitute one and the same instrument.

    SECTION 16.  Headings.  The headings herein are inserted for convenience of reference only and are not intended to be part of, or to affect the meaning or interpretation of, this Agreement.

The Trust shall not borrow money, issue debt or reinvest proceeds derived from investments, pledge any of its assets or otherwise undertake (or permit to be undertaken) any activity that would cause the Trust not to be classified for United States federal income tax purposes as a grantor trust. The Depositor hereby appoints the Trustees as trustees of the Trust, to have all the rights, powers and duties to the extent set forth herein, and the Trustees hereby accept such appointment. The Property Trustee hereby declares that it will hold the Trust Property in trust upon and subject to the conditions set forth herein for the benefit of the Trust and the Securityholders.

    (I) after an Event of Default, the taking of any action incidental to the foregoing as the Property Trustee may from time to time determine is necessary or advisable to give effect to the terms of this Declaration of Trust and protect and conserve the Trust Property for the benefit of the Securityholders (without consideration of the effect of any such action on any particular Securityholder);

    (J) subject to this Section 2.7(a)(ii), the Property Trustee shall have none of the duties, liabilities, powers or the authority of the Administrative Trustees set forth in Section 2.7(a)(i); and

    (K) to act as Paying Agent and/or Securities Registrar to the extent appointed as such hereunder.

    (b) So long as this Declaration of Trust remains in effect, the Trust (or the Trustees acting on behalf of the Trust) shall not undertake any business, activities or transaction except as expressly provided herein or contemplated hereby. In particular, the Trust shall not, and the Trustees shall not and shall cause the Trust not to (i) invest any proceeds received by the Trust from holding the Debentures (rather, the Trustees shall distribute all such proceeds to the Securityholders pursuant to the terms of this Declaration of Trust and the Trust Securities), acquire any investments or engage in any activities not authorized by this Declaration of Trust, (ii) sell, assign, transfer, exchange, mortgage, pledge, set-off or otherwise dispose of any of the Trust Property or interests therein, including to Securityholders, except as expressly provided herein, (iii) take any action that would cause the Trust to fail or cease to qualify as a "grantor trust" for United States federal income tax purposes, (iv) make any loans or incur any indebtedness for borrowed money or issue any other debt, (v) take or consent to any action that would result in the placement of a Lien on any of the Trust Property, (vi) possess any power or otherwise act in such a way as to vary the Trust assets or the terms of the Trust Securities in any way whatsoever except as permitted by the terms of this Declaration of Trust, or (vii) issue any securities or other evidences of beneficial ownership of, or beneficial interest in, the Trust other than the Trust Securities. The Administrative Trustees shall defend all claims and demands of all Persons at any time claiming any Lien on any of the Trust Property adverse to the interest of the Trust or the Securityholders in their capacity as Securityholders.

    (c) In connection with the issue and sale of the Preferred Securities, the Depositor shall have the right and responsibility to assist the Trust with respect to, or effect on behalf of the Trust, the following actions (and any actions taken by the Depositor in furtherance of the following prior to the date of this Declaration of Trust are hereby ratified and confirmed in all respects):

     (i) to cause the Trust to enter into, and to execute, deliver and perform on behalf of the Trust, the Underwriting Agreement and the Certificate Depositary Agreement and such other agreements as may be necessary or incidental to the purposes and functions of the Trust;

11

Depositor deems necessary or advisable in order to comply with the applicable laws of any such States and foreign jurisdictions;

    (iv) to the extent necessary, to prepare for filing by the Trust with the Commission and to execute on behalf of the Trust a registration statement on Form 8-A relating to the registration of the Preferred Securities under Section 12(b) or 12(g) of the Securities Exchange Act of 1934, as amended, including any amendments thereto, and to assist in the listing of the Preferred Securities upon such securities exchange or exchanges as shall be determined by the Depositor;

    (vi) any other actions necessary or incidental to carry out any of the foregoing activities.

    (d) Notwithstanding anything herein to the contrary, the Administrative Trustees are authorized and directed to conduct the affairs of the Trust and to operate the Trust so that the Trust will not be deemed to be an "investment company" required to be registered under the 1940 Act, or taxed as a corporation for United States federal income tax purposes and so that the Debentures will be treated as indebtedness of the Depositor for United States federal income tax purposes. In this connection, the Depositor and the Administrative Trustees are authorized to take any action, not inconsistent with applicable law, the Certificate of Trust or this Declaration of Trust, that each of the Depositor and the Administrative Trustees determines in their discretion to be necessary or desirable for such purposes, so long as such action does not adversely affect in any material respect the interests of the Holders of the Preferred Securities except as otherwise provided in Section 10.2(a).

SECTION 2.8.  Assets of Trust.  The assets of the Trust shall consist of only the Trust Property.

SECTION 2.9.  Title to Trust Property.  Legal title to all Trust Property shall be vested at all times in the Property Trustee (in its capacity as such) and shall be held and administered by the Property Trustee for the benefit of the Trust and the Securityholders in accordance with this Declaration of Trust. Each Securityholder shall not have legal title to any part of the assets of the Trust, but shall have an undivided beneficial interest in the assets of the Trust.

ARTICLE 3

    (a) On or prior to the Closing Date, the Property Trustee shall establish the Payment Account. The Property Trustee and any agent of the Property Trustee shall have exclusive control and sole right of withdrawal with respect to the Payment Account for the purpose of making deposits in and withdrawals from the Payment Account in accordance with this Declaration of Trust. All monies and other property deposited or held from time to time in the Payment Account shall be held by the Property Trustee in the Payment Account for the exclusive benefit of the Securityholders and for distribution as herein provided, including (and subject to) any priority of payments provided for herein.

    (b) The Property Trustee shall deposit in the Payment Account, promptly upon receipt, all payments of principal of or interest on, and any other payments or proceeds with respect to, the Debentures.

ARTICLE 4

DISTRIBUTIONS; REDEMPTION; EXCHANGE

SECTION 4.1.  Distributions.

    (a) Distributions on the Trust Securities shall be cumulative, and shall accrue from the date of original issuance, or the most recent Distribution Date (as defined herein) and shall be payable quarterly in arrears on March 16, June 16, September 16 and December 16 of each year, commencing on March 16, 2002 when, as and if available for payment by the Property Trustee, as further described in paragraph (c) of this Section 4.1.

    (b) The Trust Securities represent undivided beneficial interests in the Trust Property, and the Distributions on the Trust Securities shall be payable initially at a rate of 7.50% per annum (the "Coupon Rate") of the Liquidation Amount of the Trust Securities, through and including September 16, 2004, and at the Reset Rate thereafter. The term "Distributions" as used herein includes such cash distributions and any Additional Sums payable unless otherwise stated. The amount of Distributions payable for any period shall be computed on the basis of a 360-day year of twelve 30-day months. For periods less than a full month, Distributions shall be computed on the basis of the actual number of elapsed days.

    (c) Distributions on the Trust Securities shall be made by the Property Trustee from the Payment Account and shall be payable on each Distribution Date only to the extent that the Trust has funds then on hand and available in the Payment Account for the payment of such Distributions.

    (d) Distributions on the Trust Securities with respect to a Distribution Date shall be payable to the Holders thereof as they appear on the Securities Register for the Trust Securities on the relevant record date, which, for so long as the Preferred Securities are in the form of a Global Certificate, shall be the date which is the Business Day next preceding such Distribution Date. The relevant record dates for the Common Securities shall be the same record date as for the Preferred Securities. If the Preferred Securities shall not continue to remain in book-entry only form or are not in book-entry only form at issuance, the relevant record dates for the Preferred Securities shall conform to the rules of any securities exchange on which the Preferred Securities are listed and, if none, as shall be selected by the Administrative Trustees, which dates shall be at least more than one, but less than 60 Business Days before the relevant Distribution Dates. Distributions payable on any Trust Securities that are not punctually paid on any Distribution Date, as a result of the Depositor having failed to make a payment under the Debentures, will cease to be payable to the Person in whose name such Trust Securities are registered on the relevant record date, and such defaulted Distribution will instead be payable to the Person in whose name such Trust Securities are registered on the special record date or other specified date determined in accordance with the Indenture in respect of a corresponding payment on the Debentures. If any date on which Distributions are payable on the Trust Securities is not a Business Day, then payment of the Distribution payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay) except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date (each such date on which Distributions are payable under this Section 4.1, a "Distribution Date"). So long as the Collateral Agent is a Holder of any Preferred Securities, the payment of distributions on such Preferred Securities held by the Collateral Agent will be made at such place and to such account as may be designated by the Collateral Agent.

13

    (e) The Depositor shall advise, or cause the Reset Agent to advise, by telephone promptly confirmed in writing, the Depositary, the Property Trustee, the Purchase Contract Agent and the Debenture Trustee of the Reset Rate determined in accordance with the Remarketing Agreement. The Depositor will cause a notice of the Reset Rate to be published on the second Business Day following the Remarketing Date and any such Subsequent Remarketing Date in The Wall Street Journal, or if such publication ceases to publish notices of such type, or if it is otherwise impractical to publish such notice therein, in such other daily newspaper of general circulation in The City of New York published in the English language, as the Depositor may reasonably determine.

    (f)  In the event that there is any money or other property held by or for the Trust that is not accounted for hereunder, such property shall be distributed on a pro rata basis (based upon Liquidation Amounts) among the Holders of the Securities, subject to Section 4.5.

SECTION 4.2.  [INTENTIONALLY OMITTED]

SECTION 4.3.  [INTENTIONALLY OMITTED]

SECTION 4.4.  Tax Event Redemption.

    (a) On the Redemption Date the Property Trustee shall redeem each Outstanding Trust Security and distribute in respect of each Trust Security the "redemption amount" applicable thereto, as determined below, from the proceeds of the Tax Event Redemption.

     (i) In the event the Tax Event Redemption occurs after (I) a successful remarketing of the Preferred Securities under the Remarketing Agreement or (II) the Stock Purchase Date, the "redemption amount" with respect to each Outstanding Trust Security shall be the Liquidation Amount thereof, together with accrued and unpaid Distributions thereon;

    (ii) In the event the Tax Event Redemption occurs prior to (I) a successful remarketing of the Preferred Securities under the Remarketing Agreement or (II) the Stock Purchase Date, the "redemption amount" with respect to (I) each Common Security and each Preferred Security not held as part of a Normal Unit, shall be the Liquidation Amount thereof, together with accrued and unpaid Distributions thereon, and (II) each Preferred Security held as part of a Normal Unit, shall be the pro rata portion of the price of the Treasury Redemption Portfolio distributed by the Debenture Trustee to the Property Trustee on the Tax Redemption Date.

    (b) The redemption amount payable in respect of each Common Security and each Preferred Security not held as part of a Normal Unit shall be payable in cash to the record Holder thereof. The redemption amount payable in respect of each Preferred Security held as part of a Normal Unit shall be payable in cash and distributed to the Collateral Agent on behalf of such Holder to be held as security for such Holder's obligations to the Depositor under the Purchase Contracts with respect to such Normal Unit.

    (c) In the event of a Tax Event Redemption the Depositor shall irrevocably notify the Property Trustee of the Redemption Date not more than 60 nor less than 30 days prior to the Redemption Date, and shall cooperate with the Property Trustee in providing all required notices to the Holders hereunder. The Property Trustee shall provide a written notice (a "Tax Event Redemption Notice") by first-class mail to each record Holder not more than 60 nor less than 30 days prior to the Redemption Date. For purposes of the calculation of the date of redemption and the dates on which notices are given pursuant to this paragraph (c), a Tax Event Redemption Notice shall be deemed to be given on the day such notice is first mailed by first-class mail, postage prepaid, to each Holder. Each Tax Event Redemption Notice shall be addressed to each Holder of Trust Securities at the address of such Holder appearing in the books and records of the

14

Trust. Each Tax Event Redemption Notice shall state: (A) the Redemption Date; (B) the aggregate Liquidation Amount and any unpaid Distributions (including any Additional Sums) on the Trust Securities to be redeemed; (C) that on the Redemption Date the Trust Securities shall be redeemed for the redemption amount and that Distributions on the Trust Securities so redeemed will cease to accumulate on and after said date; and (D) the place or places where each Trust Certificate to be redeemed is to be surrendered for redemption. No defect in the Redemption Notice or in the mailing thereof with respect to any Trust Security shall affect the validity of the redemption proceedings for any other Trust Security.

    (d) Nothing in this Section 4.4 shall limit the requirement of the Trust to withhold taxes pursuant to the terms of the Trust Securities, as set forth in this Agreement or under applicable law or otherwise require the Property Trustee or the Trust to pay any amounts on account of such withholdings.

SECTION 4.5.  Subordination of Common Securities.  Payment of Distributions (including Additional Amounts, if applicable) on the Trust Securities shall be made pro rata based on the Liquidation Amount of the Trust Securities; provided, however, that if on any Distribution Date an Event of Default shall have occurred and be continuing, no payment of any Distribution (including Additional Amounts, if applicable) on any Common Security, and no other payment on account of the redemption, liquidation or other acquisition of Common Securities, shall be made unless payment in full in cash of all accumulated and unpaid Distributions (including Additional Amounts, if applicable) on all Outstanding Preferred Securities for all Distribution periods terminating on or prior thereto shall have been made or provided for, and all funds immediately available to the Property Trustee shall first be applied to the payment in full in cash of all Distributions (including Additional Amounts, if applicable) on Preferred Securities then due and payable.

SECTION 4.6.  Payment Procedures.  Payments in respect of the Preferred Securities shall be made by check mailed to the address of the Person entitled thereto as such address shall appear on the Securities Register or, if the Preferred Securities are held by a Clearing Agency, such Distributions shall be made to the Clearing Agency in immediately available funds, in accordance with the Certificate Depositary Agreement on the applicable Distribution Dates. Payments in respect of the Common Securities shall be made in such manner as shall be mutually agreed between the Property Trustee and the Holder of the Common Securities.

SECTION 4.7.  Tax Returns and Reports.  The Administrative Trustees shall prepare (or cause to be prepared), at the Depositor's expense, and file (or cause to be filed) all United States federal, state and local tax and information returns and reports required to be filed by or in respect of the Trust. In this regard, the Administrative Trustees shall (a) prepare and file (or cause to be prepared or filed) Form 1041 or the appropriate Internal Revenue Service form required to be filed in respect of the Trust in each taxable year of the Trust and (b) prepare and furnish (or cause to be prepared and furnished) to each Security holder a Form 1099 or the appropriate Internal Revenue Service form required to be furnished to such Securityholder or the information required to be provided on such form. The Administrative Trustees shall provide (or cause to be provided) the Depositor and the Property Trustee with a copy of all such returns, reports and schedules promptly after such filing or furnishing. The Administrative Trustees shall comply with United States federal withholding and backup withholding tax laws and information reporting requirements with respect to any payments to Securityholders under the Trust Securities.

SECTION 4.8.  Payment of Taxes, Duties, Etc. of the Trust.  Upon receipt under the Debentures of Additional Sums, the Property Trustee, upon receipt of written notice from the Depositor or the Administrative Trustees, shall promptly pay from such Additional Sums any taxes, duties or governmental charges of whatever nature (other than withholding taxes), as indicated in such notice, imposed on the Trust by the United States or any other taxing authority.

15

SECTION 4.9.  Payments under Indenture.  Any amount payable hereunder to any Holder of Preferred Securities (and any Owner with respect thereto) shall be reduced by the amount of any corresponding payment such Holder (or Owner) has directly received pursuant to Article V of the Indenture in accordance with the terms of Section 6.8 hereof.

ARTICLE 5

TRUST SECURITIES CERTIFICATES

SECTION 5.1.  Initial Ownership.  Upon the formation of the Trust and until the issuance of the Trust Securities, and at any time during which no Trust Securities are Outstanding, the Depositor shall be the sole beneficial owner of the Trust.

SECTION 5.2.  The Trust Securities Certificates.  The Preferred Securities Certificates shall be issued in minimum authorized denominations of $50 Liquidation Amount and integral multiples of $50 in excess thereof, and the Common Securities Certificates shall be issued in denominations of $50 Liquidation Amount and integral multiples thereof. The consideration received by the Trust for the issuance of the Trust Securities shall constitute a contribution to the capital of the Trust and shall not constitute a loan to the Trust. Initially the Preferred Securities will be represented by one certificate registered in the name of BNY Western Trust Company, as Purchase Contract Agent and one zero balance certificate registered in the Securities Register in the name of a Clearing Agency or a nominee thereof, in global form (the "Global Certificate"). The Trust Securities Certificates shall be executed on behalf of the Trust by manual or facsimile signature of at least one Administrative Trustee and the Preferred Securities Certificates shall be authenticated by the Property Trustee. Trust Securities Certificates bearing the manual or facsimile signatures of individuals who were, at the time when such signatures shall have been affixed, authorized to sign on behalf of the Trust, shall be validly issued and entitled to the benefit of this Declaration of Trust, notwithstanding that such individuals or any of them shall have ceased to be so authorized prior to the delivery of such Trust Securities Certificates or did not hold such offices at the date of delivery of such Trust Securities Certificates. A transferee of a Trust Securities Certificate shall become a Securityholder, and shall be entitled to the rights and subject to the obligations of a Securityholder hereunder, upon due registration of such Trust Securities Certificate in such transferee's name pursuant to Section 5.4.

SECTION 5.3.  Delivery of Trust Securities Certificates.  On the Closing Date, the Administrative Trustees shall cause Trust Securities Certificates, in an aggregate Liquidation Amount as provided in Sections 2.4 and 2.5, to be executed (which execution may be manual or by facsimile) on behalf of the Trust and delivered to or upon the written order of the Depositor, signed by its Chairman of the Board, any Vice Chairman, its President, or any Vice President, Treasurer or Assistant Treasurer or Controller without further corporate action by the Depositor, in authorized denominations.

    A Common Securities Certificate shall not be valid until executed by at least one Administrative Trustee. A Preferred Securities Certificate shall not be valid until authenticated by the manual signature of an authorized signatory of the Property Trustee. The signature shall be conclusive evidence that the Preferred Securities Certificate has been authenticated under this Declaration of Trust. Upon a written order of the Trust signed by one Administrative Trustee, the Property Trustee shall authenticate the Preferred Securities Certificates for original issue.

    The Property Trustee may appoint an authenticating agent acceptable to the Administrative Trustees to authenticate Preferred Securities Certificates. An authenticating agent may authenticate Preferred Securities Certificates whenever the Property Trustee may do so. Each reference in this Declaration of Trust to authentication by the Property Trustee includes authentication by such agent. An authenticating agent has the same rights as the Property Trustee to deal with the Depositor or an Affiliate with respect to the authentication of Preferred Securities.

16

SECTION 5.4.  Registration of Transfer and Exchange of Preferred Securities.  The Administrative Trustees shall appoint a securities registrar (the "Securities Registrar"). The Securities Registrar shall keep or cause to be kept, at the office or agency maintained pursuant to Section 5.8, a securities register (the "Securities Register") in which, subject to such reasonable regulations as it may prescribe, the Securities Registrar shall provide for the registration of Preferred Securities Certificates and Common Securities Certificates (subject to Section 5.10 in the case of the Common Securities Certificates) and registration of transfers and exchanges of Preferred Securities Certificates as herein provided. The Property Trustee shall be the initial Securities Registrar.

    Upon surrender for registration of transfer of any Preferred Security at an office or agency of the Depositor designated pursuant to Section 5.8 for such purpose, the Depositor shall execute, and the Property Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Preferred Securities of any authorized denominations and of a like aggregate principal amount.

    At the option of the Holder, and subject to the other provisions of this Section 5.4, Preferred Securities may be exchanged for other Preferred Securities of any authorized denomination and of a like Liquidation Amount, upon surrender of the Preferred Securities to be exchanged at any such office or agency. Whenever any Preferred Securities are so surrendered for exchange, the Depositor shall execute, and the Property Trustee shall authenticate and deliver, the Preferred Securities which the Holder making the exchange is entitled to receive.

    All Preferred Securities issued upon any registration of transfer or exchange of Preferred Securities shall be the valid obligations of the Trust, evidencing the same rights, and entitled to the same benefits under this Declaration of Trust, as the Securities surrendered upon such registration of transfer or exchange.

    Every Preferred Security presented or surrendered for registration of transfer or for exchange shall (if so requested by the Securities Registrar) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Securities Registrar duly executed, by the Holder thereof or such Holder's attorney duly authorized in writing.

    No service charge shall be made for any registration of transfer or exchange of Preferred Securities Certificates, but the Securities Registrar may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer or exchange of Preferred Securities Certificates.

SECTION 5.5.  Mutilated, Destroyed, Lost or Stolen Trust Securities Certificates.  If (a) any mutilated Trust Securities Certificate shall be surrendered to the Securities Registrar, or if the Securities Registrar shall receive evidence to its satisfaction of the destruction, loss or theft of any Trust Securities Certificate and (b) there shall be delivered to the Securities Registrar and the Administrative Trustees such security or indemnity as may be required by them to save each of them harmless, then in the absence of notice that such Trust Securities Certificate shall have been acquired by a protected purchaser, the Administrative Trustees, or any one of them, on behalf of the Trust shall execute and make available for authentication, where applicable, and delivery, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Trust Securities Certificate, a new Trust Securities Certificate of like denomination. In connection with the issuance of any new Trust Securities Certificate under this Section, the Securities Registrar may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith. Any duplicative Trust Securities Certificate issued pursuant to this Section shall constitute conclusive evidence of an undivided beneficial interest in the assets of the Trust, as if originally issued, whether or not the lost, stolen or destroyed Trust Securities Certificate shall be found at any time.

17

SECTION 5.6.  Persons Deemed Securityholders.  The Property Trustee and the Securities Registrar shall treat the Person in whose name any Trust Securities Certificate shall be registered in the Securities Register as the owner of such Trust Securities Certificate for the purpose of receiving Distributions and for all other purposes whatsoever, and neither the Property Trustee nor the Securities Registrar shall be bound by any notice to the contrary.

SECTION 5.7.  Access to List of Securityholders' Names and Addresses.  The Administrative Trustees or the Depositor shall furnish or cause to be furnished (unless the Property Trustee is acting as Securities Registrar with respect to the Trust Securities under the Declaration of Trust) a list, in such form as the Property Trustee may reasonably require, of the names and addresses of the Securityholders as of the most recent record date (a) to the Property Trustee, quarterly at least 5 Business Days before each Distribution Date, and (b) to the Property Trustee, as promptly as practicable after receipt by the Depositor of a request therefor from the Property Trustee in order to enable the Property Trustee to discharge its obligations under this Declaration of Trust, in each case to the extent such information is in the possession or control of the Administrative Trustees or the Depositor and is not identical to a previously supplied list or has not otherwise been received by the Property Trustee in its capacity as Securities Registrar. The rights of Securityholders to communicate with other Securityholders with respect to their rights under this Declaration of Trust or under the Trust Securities, and the corresponding rights of the Trustee shall be as provided in the Trust Indenture Act, except to the extent Section 3819 of the Delaware Business Trust Act would require greater access to such information, in which case the latter shall apply. Each Holder, by receiving and holding a Trust Securities Certificate, and each Owner shall be deemed to have agreed not to hold the Depositor, the Property Trustee or the Administrative Trustees accountable by reason of the disclosure of its name and address, regardless of the source from which such information was derived.

SECTION 5.8.  Maintenance of Office or Agency.  The Securities Registrar shall maintain in The City of New York an office or offices or agency or agencies where Preferred Securities Certificates may be surrendered for registration of transfer, exchange or conversion and where notices and demands to or upon the Trustees in respect of the Trust Securities Certificates may be served. The Securities Registrar initially designates BNY Western Trust Company, c/o The Bank of New York, Corporate Trust Window, 15 Broad Street, New York, New York 10007, as its principal corporate trust office for such purposes. The Securities Registrar shall give prompt written notice to the Depositor and to the Securityholders of any change in the location of the Securities Register or any such office or agency.

SECTION 5.9.  Appointment of Paying Agent.  In the event that the Preferred Securities are not in book-entry form only, the Trust shall maintain in the Borough of Manhattan, The City of New York, an office or agency (the "Paying Agent") where the Preferred Securities may be presented for payment. The Paying Agent shall make Distributions to Securityholders from the Payment Account and shall report the amounts of such Distributions to the Property Trustee and the Administrative Trustees. Any Paying Agent shall have the revocable power to withdraw funds from the Payment Account for the purpose of making the Distributions referred to above. The Administrative Trustees may revoke such power and remove the Paying Agent if such Trustees determine in their sole discretion that the Paying Agent shall have failed to perform its obligations under this Declaration of Trust in any material respect. The Paying Agent shall initially be the Property Trustee, and any co-paying agent chosen by the Property Trustee and acceptable to the Administrative Trustees and the Depositor in their sole discretion. Any Person acting as Paying Agent shall be permitted to resign as Paying Agent upon 30 days' written notice to the Property Trustee and the Depositor. In the event that the Property Trustee shall no longer be the Paying Agent or a successor Paying Agent shall resign or its authority to act be revoked, the Administrative Trustees shall appoint a successor that is reasonably acceptable to the Property Trustee and the Depositor to act as Paying Agent (which shall be a bank or trust company). Each successor Paying Agent or any additional Paying Agent shall agree with the Trustees that, as Paying Agent, such successor Paying Agent or additional Paying Agent will hold all sums, if

18

any, held by it for payment to the Securityholders in trust for the benefit of the Securityholders entitled thereto until such sums shall be paid to each Securityholder. The Paying Agent shall return all unclaimed funds to the Property Trustee and upon removal of a Paying Agent such Paying Agent shall also return all funds in its possession to the Property Trustee. The provisions of Sections 8.1, 8.3 and 8.6 shall apply to the Property Trustee also in its role as Paying Agent, for so long as the Property Trustee shall act as Paying Agent and, to the extent applicable, to any other paying agent appointed hereunder. Any reference in this Agreement to the Paying Agent shall include any co-paying agent unless the context requires otherwise.

SECTION 5.10.  Ownership of Common Securities by Depositor.  On the Closing Date, the Depositor shall acquire and retain beneficial and record ownership of the Common Securities. To the fullest extent permitted by law, and except as provided in the following sentence, any attempted transfer of the Common Securities shall be void. Subject to this Article 5, the Depositor and any Related Party may only transfer Common Securities to the Depositor or a Related Party of the Depositor; provided that, any such transfer is subject to the condition precedent that the transferor obtain the written opinion of nationally recognized independent counsel experienced in such matters that such transfer would not cause more than an insubstantial risk that:

     (i) the Trust would not be classified for United States federal income tax purposes as a grantor trust; and

    (ii) the Trust would be an Investment Company or the transferee would become an Investment Company.

The Administrative Trustees shall cause each Common Securities Certificate issued to the Depositor to contain a legend stating "THIS CERTIFICATE IS NOT TRANSFERABLE EXCEPT AS SPECIFICALLY PERMITTED UNDER THE AMENDED AND RESTATED DECLARATION OF TRUST OF BOISE CASCADE TRUST I."

SECTION 5.11.  Global Securities; Non-Global Securities; Common Securities Certificate.

    (a) Each Global Certificate authenticated under this Declaration of Trust in addition to being issued in the form of one or more definitive, fully registered Preferred Securities Certificates registered initially in the books and records of the Trust in the name of BNY Western Trust Company, as Purchase Contract Agent, may, at the option of the Depositor, be registered in the name of the Clearing Agency designated by the Depositor for such Global Certificate or a nominee thereof and delivered to such Clearing Agency or a nominee thereof or custodian therefor, and each such Global Certificate shall constitute a Preferred Security for all purposes of this Declaration of Trust.

    (b) If a Global Certificate is to be exchanged for Certificated Preferred Securities or cancelled in whole, it shall be surrendered by or on behalf of the Clearing Agency, its nominee or custodian to the Property Trustee, as Securities Registrar, for exchange or cancellation as provided in this Article 5. If any Global Certificate is to be exchanged for Certificated Preferred Securities or cancelled in part, or if another Preferred Security is to be exchanged in whole or in part for a beneficial interest in any Global Certificate, in each case, as provided in Section 5.4, then either (i) such Global Certificate shall be so surrendered for exchange or cancellation as provided in this Article 5 or (ii) the Liquidation Amount thereof shall be reduced or increased by an amount equal to the portion thereof to be so exchanged or cancelled, or equal to the principal amount of such Certificated Preferred Security to be so exchanged for a beneficial interest therein, as the case may be, by means of an appropriate adjustment made on the records of the Property Trustee, as Securities Registrar, whereupon the Property Trustee, in accordance with the Applicable Procedures, shall instruct the Clearing Agency or its authorized representative to make a corresponding adjustment to its records. Upon any such surrender or adjustment of a Global

19

Certificate, the Property Trustee shall, subject to Section 5.4 and as otherwise provided in this Article 5, authenticate and deliver any Preferred Securities issuable in exchange for such Global Certificate (or any portion thereof) to or upon the order of, and registered in such names as may be directed by, the Clearing Agency or its authorized representative.

    Upon the request of the Property Trustee in connection with the occurrence of any of the events specified in the preceding paragraph, the Depositor shall cause as promptly as practicable to be made available to the Property Trustee a reasonable supply of Preferred Securities that are not in the form of Global Certificates. The Property Trustee shall be entitled to conclusively rely upon any order, direction or request of the Clearing Agency or its authorized representative which is given or made pursuant to this Article 5 if such order, direction or request is given or made in accordance with the Applicable Procedures.

    (c) Every Preferred Security authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Certificate or any portion thereof, whether pursuant to this Article 5 or otherwise, shall be authenticated and delivered in the form of, and shall be, a Global Certificate, unless such Preferred Security is registered in the name of a Person other than the Clearing Agency for such Global Certificate or a nominee thereof.

    (d) The Clearing Agency or its nominee, as registered owner of a Global Certificate, shall be the holder of such Global Certificate for all purposes under the Declaration of Trust and the Preferred Securities, and owners of beneficial interests in a Global Certificate shall hold such interests pursuant to the Applicable Procedures. Accordingly, any such Owner's beneficial interest in a Global Certificate will be shown only on, and the transfer of such interest shall be effected only through, records maintained by the Clearing Agency or its nominee or its participants and such owners of beneficial interests in a Global Certificate will not be considered the owners or holders of such Global Certificate for any purpose of this Declaration of Trust or the Preferred Securities.

    (e) A single Common Securities Certificate representing the Common Securities shall be registered in the name of and issued to the Depositor in the form of a definitive Common Securities Certificate.

SECTION 5.12.  Notices to Clearing Agency.  To the extent that a notice or other communication to the Owners is required under this Declaration of Trust, unless and until Definitive Preferred Securities Certificates shall have been issued to Owners pursuant to Section 5.13, the Administrative Trustees and the Property Trustee shall give all such notices and communications specified herein to be given to Owners to the Clearing Agency, and shall have no obligations to provide notices directly to the Owners.

SECTION 5.13.  Definitive Preferred Securities Certificates.  Notwithstanding any other provision in this Declaration of Trust, no Global Certificate may be exchanged in whole or in part for Preferred Securities registered, and no transfer of a Global Certificate in whole or in part may be registered, in the name of any Person other than the Clearing Agency for such Global Certificate or a nominee thereof unless (i) such Clearing Agency (A) has notified the Depositor that it is unwilling or unable to continue as Clearing Agency for such Global Certificate or (B) has ceased to be a clearing agency registered as such under the Securities Exchange Act of 1934, as amended, and in either case the Trust and the Depositor thereupon fails to appoint a successor Clearing Agency, (ii) the Depositor, at its option, notifies the Property Trustee in writing that it elects to cause the issuance of the Preferred Securities in certificated form, or (iii) there shall have occurred and be continuing an Event of Default or any event which after notice or lapse of time or both would be an Event of Default. In all cases, Certificated Preferred Securities delivered in exchange for any Global Certificate or beneficial interests therein will be registered in the names, and issued in any authorized denominations, requested by or on behalf of the Clearing Agency (in accordance with its customary procedures).

20

SECTION 5.14.  Rights of Securityholders.  The legal title to the Trust Property is vested exclusively in the Property Trustee (in its capacity as such) in accordance with Section 2.9, and the Securityholders shall not have any right or title therein other than the undivided beneficial interest in the assets of the Trust conferred by their Trust Securities and they shall have no right to call for any partition or division of property, profits or rights of the Trust except as described below. The Trust Securities shall be personal property giving only the rights specifically set forth therein and in this Declaration of Trust. The Trust Securities shall have no preemptive or similar rights and, when issued and delivered to Securityholders against payment of the purchase price therefor, will be fully paid and nonassessable by the Trust. The Holders of the Trust Securities, in their capacities as such, shall be entitled to the same limitation of personal liability extended to stockholders of private corporations for profit organized under the General Corporation Law of the State of Delaware. Except as expressly set forth in this Declaration of Trust, the Debentures, the Securities Guarantees and the terms of the Securities, the Depositor shall not be:

     (i) personally liable for the return of any portion of the capital contributions (or any return thereon) of the Holders of the Securities, which shall be made solely from assets of the Trust; or

    (ii) required to pay to the Trust or to any Holder of Securities any deficit upon dissolution of the Trust or otherwise.

SECTION 5.15.  CUSIP Numbers.  The Trust in issuing the Trust Securities may use "CUSIP" numbers (if then generally in use), and, if so, the Property Trustee shall use "CUSIP" numbers in notices of redemption as a convenience to Securityholders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Trust Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Trust Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Depositor will promptly notify the Trustees of any change in the "CUSIP" numbers.

ARTICLE 6

ACT OF SECURITYHOLDERS; MEETINGS; VOTING

SECTION 6.1.  Limitations on Voting Rights.

    (a) Except as provided in this Section, in Sections 8.2 and 10.2 and in the Indenture and as otherwise required by law, no Holder of Preferred Securities shall have any right to vote or in any manner otherwise control the administration, operation and management of the Trust or the obligations of the parties hereto, nor shall anything herein set forth, or contained in the terms of the Trust Securities Certificates, be construed so as to constitute the Securityholders from time to time as partners or members of an association.

    (b) Subject to Section 8.2 hereof and the requirements set forth in this paragraph, the Holders of a majority in Liquidation Amount of Preferred Securities, voting separately as a class may direct the time, method, and place of conducting any proceeding for any remedy available to the Property Trustee, or the exercise of any trust or power conferred upon the Property Trustee under the Declaration of Trust, including (i) directing the time, method and place of conducting any proceeding for any remedy available to the Debenture Trustee, or exercising any trust or power conferred on the Debenture Trustee with respect to the Debentures, (ii) waiving any past default and its consequences that is waivable under the Indenture, (iii) exercising any right to rescind or annul a declaration that the principal of all the Debentures shall be due and payable, or (iv) consenting to any amendment, modification or termination of the Indenture or the Debentures where such consent shall be required, provided, however, that, where a consent or action under the

21

Indenture specifically would require the consent or act of the Holders of greater than a majority of the holders in principal amount of Debentures affected thereby (a "Super Majority"), the Property Trustee may only give such consent or take such action at the written direction of the Holders of at least the proportion in Liquidation Amount of the Preferred Securities which the relevant Super Majority represents of the aggregate principal amount of the Debentures outstanding. The Property Trustee shall not revoke any action previously authorized or approved by a vote of the Holders of the Preferred Securities. Other than with respect to directing the time, method and place of conducting any remedy available to the Property Trustee or the Debenture Trustee as set forth above, the Property Trustee shall not take any action in accordance with the directions of the Holders of the Preferred Securities under this paragraph unless the Property Trustee has obtained an opinion of tax counsel to the effect that for the purposes of United States federal income tax the Trust will not be classified as other than a grantor trust on account of such action.

    (c) Except as provided under this Section, Sections 8.2, 8.9 and 10.2 and as otherwise required by law and the Declaration of Trust, the Holders of the Common Securities will have no voting rights.

    (d) Subject to Section 8.2 of the Declaration of Trust and only after any Event of Default with respect to the Preferred Securities has been cured, waived, or otherwise eliminated, the Property Trustee shall not (i) direct the time, method, and place of conducting any proceeding for any remedy available to the Debenture Trustee, or exercising any trust or power conferred on the Debenture Trustee with respect to the Debentures, (ii) waive any past default and its consequences that is waivable under the Indenture, or (iii) exercise any right to rescind or annul a declaration that the principal of all the Debentures shall be due and payable, without in each case, obtaining the prior approval of the Holders of a majority in Liquidation Amount of Common Securities, provided that, where a consent under the Indenture specifically would require the consent of the Holders of a Super Majority, the Property Trustee may only give such consent at the written direction of the Holders of at least the proportion in Liquidation Amount of the Common Securities which the relevant Super Majority represents of the aggregate principal amount of the Debentures outstanding. Pursuant to this Section 6.1(d), the Property Trustee shall not revoke any action previously authorized or approved by a vote of the Holders of the Preferred Securities. The Property Trustee Shall not take any of the foregoing actions under this paragraph unless the Property Trustee has obtained an opinion of tax counsel to the effect that for the purposes of United States federal income tax the Trust will not be classified as other than a grantor trust on account of such action. If the Property Trustee fails to enforce its rights under the Declaration of Trust, any Holder of Common Securities may, to the fullest extent permitted by law, institute a legal proceeding directly against any Person to enforce the Property Trustee's rights under the Declaration of Trust, without first instituting a legal proceeding against the Property Trustee or any other Person.

    Any approval or direction of the Holders of Common Securities may be given at a separate meeting of Holders of Common Securities convened for such purposes, at a meeting of all of the Holders of Securities in the Trust or pursuant to written consent. The Administrative Trustees will cause a notice of any meeting at which Holders of Common Securities are entitled to vote to be mailed to each Holder of record of Common Securities, Each such notice will include a statement setting forth (i) the date of such meeting, (ii) a description of any resolution proposed for adoption at such meeting on which such Holders are entitled to vote and (iii) instructions for the delivery of proxies.

    (e) If any proposed amendment to the Declaration of Trust provides for, or the Trustees otherwise propose to effect, the dissolution, winding-up or termination of the Trust, other than pursuant to the terms of this Declaration of Trust, then the Holders of Outstanding Preferred Securities as a class will be entitled to vote on such amendment or proposal and such amendment

22

or proposal shall not be effective except with the approval of the Holders of a majority in aggregate Liquidation Amount of the Outstanding Preferred Securities.

SECTION 6.2.  Notice of Meetings.  Notice of all meetings of the Holders of the Preferred Securities, stating the time, place and purpose of the meeting, shall be given by the Property Trustee pursuant to Section 10.8 to each Preferred Securityholder of record, at its registered address, at least 7 days and not more than 60 days before the meeting. At any such meeting, any business properly before the meeting may be so considered whether or not stated in the notice of the meeting. Any adjourned meeting may be held as adjourned without further notice.

SECTION 6.3.  Meetings of Preferred Securityholders.  No annual meeting of Securityholders is required to be held. The Administrative Trustees, however, shall call a meeting of Securityholders to vote on any matter upon the written request of the Preferred Securityholders of record of 10% of the Preferred Securities (based upon their Liquidation Amount) and the Administrative Trustees or the Property Trustee may, at any time in their discretion, call a meeting of the Holders of Preferred Securities to vote on any matters as to which such Holders are entitled to vote.

    Holders of record of 50% of the Preferred Securities (based upon their Liquidation Amount), present in person or by proxy, shall constitute a quorum at any meeting of Securityholders.

    If a quorum is present at a meeting, an affirmative vote by the Holders of record of Preferred Securities present, in person or by proxy, holding more than a majority of the Preferred Securities (based upon their Liquidation Amount) held by Holders of record of Preferred Securities present, either in person or by proxy, at such meeting shall constitute the action of the Securityholders, unless this Declaration of Trust requires a greater number of affirmative votes.

SECTION 6.4.  Voting Rights.  Securityholders shall be entitled to one vote for each $50 of Liquidation Amount represented by their Trust Securities in respect of any matter as to which such Securityholders are entitled to vote. Notwithstanding that holders of Preferred Securities are entitled to vote or consent under any of the circumstances described above, any of the Preferred Securities that are owned at such time by the Depositor, the Trustees or any affiliate of any Trustee shall, for purposes of such vote or consent, be treated as if such Preferred Securities were not outstanding.

SECTION 6.5.  Proxies, Etc.  At any meeting of Securityholders, any Securityholders entitled to vote thereat may vote by proxy, provided that no proxy shall be voted at any meeting unless it shall have been placed on file with the Administrative Trustees, or with such other officer or agent of the Trust as the Administrative Trustees may direct, for verification prior to the time at which such vote shall be taken. Pursuant to a resolution of the Property Trustee, proxies may be solicited in the name of the Property Trustee or one or more officers of the Property Trustee. Only Securityholders of record shall be entitled to vote. When Trust Securities are held jointly by several Persons, any one of them may vote at any meeting in person or represented by proxy in respect of such Trust Securities, but if more than one of them shall be present at such meeting in person or by proxy, and such joint owners or their proxies so present disagree as to any vote to be cast, such vote shall not be received in respect of such Trust Securities. A proxy purporting to be executed by or on behalf of a Securityholder shall be deemed valid unless challenged at or prior to its exercise, and the burden of proving invalidity shall rest on the challenger. No proxy shall be valid more than 11 months after its date of execution.

SECTION 6.6.  Securityholder Action by Written Consent.  Any action which may be taken by Securityholders at a meeting may be taken without a meeting if Securityholders holding more than a majority of all Outstanding Trust Securities (based upon their Liquidation Amount) entitled to vote in respect of such action (or such larger proportion thereof as shall be required by any express provision of this Declaration of Trust) shall consent to the action in writing.

SECTION 6.7.  Record Date for Voting and Other Purposes.  For the purposes of determining the Securityholders who are entitled to notice of and to vote at any meeting or by written consent, or to

23

participate in any Distribution on the Trust Securities in respect of which a record date is not otherwise provided for in this Declaration of Trust, or for the purpose of any other action, the Property Trustee may from time to time fix a date, not more than 60 days prior to the date of any meeting of Securityholders or the payment of Distributions or other action, as the case may be, as a record date for the determination of the identity of the Securityholders of record for such purposes.

SECTION 6.8.  Acts of Securityholders.  Any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Declaration of Trust to be given, made or taken by Securityholders or Owners may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Securityholders or Owners in person or by an agent duly appointed in writing; and, except as otherwise expressly provided herein, such action shall become effective when such instrument or instruments are delivered to an Administrative Trustee. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the "Act" of the Securityholders or Owners signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Declaration of Trust and (subject to Section 8.1) conclusive in favor of the Trustees, if made in the manner provided in this Section.

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

    The ownership of Preferred Securities shall be proved by the Securities Register.

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

    Without limiting the foregoing, a Securityholder entitled hereunder to take any action hereunder with regard to any particular Trust Security may do so with regard to all or any part of the Liquidation Amount of such Trust 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 Liquidation Amount.

    If any dispute shall arise between the Securityholders and the Administrative Trustees or among such Securityholders or Trustees with respect to the authenticity, validity or binding nature of any request, demand, authorization, direction, consent, waiver or other Act of such Securityholder or Trustee under this Article 6, then the determination of such matter by the Property Trustee shall be conclusive with respect to such matter.

    Upon the occurrence and continuation of an Event of Default, the holders of Preferred Securities shall rely on the enforcement by the Property Trustee of its rights as holder of the Debentures against the Depositor. If the Property Trustee fails to enforce its rights as holder of the Debentures after a request therefor and offer of indemnification satisfactory to the Property Trustee by a holder of Preferred Securities, such holder may, to the fullest extent permitted by law, proceed to enforce such rights directly against the Depositor. Notwithstanding the foregoing, if an Event of Default has occurred and is continuing and such event is attributable to the failure of the Depositor to pay interest

24

or principal on the Debentures on the date such interest or principal is otherwise payable, then a holder of Preferred Securities shall have the right to institute a proceeding directly against the Depositor, for enforcement of payment to such holder of the principal amount of or interest on Debentures having a principal amount equal to the aggregate Liquidation Amount of the Preferred Securities of such holder after the respective due date specified in the Debentures (a "Direct Action"). In connection with such Direct Action, the rights of the holders of Common Securities will be subordinate to the rights of such holder of Preferred Securities. In connection with any such Direct Action, the rights of the Depositor will be subrogated to the rights of any holder of the Preferred Securities to the extent of any payment made by the Depositor to such holder of Preferred Securities as a result of such Direct Action.

    A Securityholder may institute a legal proceeding directly against the Depositor under the Guarantee to enforce its rights under the Guarantee without first instituting a legal proceeding against the Guarantee Trustee (as defined in the Guarantee), the Trust or any Person or entity.

SECTION 6.9.  Inspection of Records.  Upon reasonable notice to the Administrative Trustees and the Property Trustee, the records of the Trust shall be open to inspection by Securityholders during normal business hours for any purpose reasonably related to such Securityholder's interest as a Securityholder.

ARTICLE 8

THE TRUSTEES

SECTION 8.1.  Certain Duties and Responsibilities.

    (a) The duties and responsibilities of the Trustees shall be as provided by this Declaration of Trust and, in the case of the Property Trustee, by the Trust Indenture Act. The Property Trustee, before the occurrence of any Event of Default and after the curing or waiving of all Events of Default that may have occurred, shall undertake to perform only such duties and obligations as are specifically set forth in this Declaration of Trust and the Trust Indenture Act and no implied covenants shall be read into this Declaration of Trust against the Property Trustee. In case an Event of Default has occurred (that has not been cured or waived pursuant to Section 8.2) of which a responsible officer of the Property Trustee has actual knowledge, the Property Trustee shall exercise such rights and powers vested in it by this Declaration of Trust and the Trust Indenture Act, and use the same degree of care and skill in its exercise, as a prudent individual would exercise or use under the circumstances in the conduct of his or her own affairs. Notwithstanding the foregoing, no provision of this Declaration of Trust shall require the Trustees to expend or risk their own funds or otherwise incur any financial liability in the performance of any of their duties hereunder, or in the exercise of any of their rights or powers, if they shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. Whether or not therein expressly so provided, every provision of this Declaration of Trust relating to the conduct or affecting the liability of or affording protection to the Trustees shall be subject to the provisions of this Section. Nothing in this Declaration of Trust shall be construed to release the Administrative Trustees or the Delaware Trustee from liability for their own grossly negligent action, their own grossly negligent failure to act, or their own willful misconduct. To the extent that, at law or in equity, an Administrative Trustee has duties (including fiduciary duties) and liabilities relating thereto to the Trust or to the Securityholders, such Administrative Trustee shall not be liable to the Trust or to any Securityholder for such Administrative Trustee's good faith reliance on the provisions of this Declaration of Trust or advice of counsel. The provisions of this Declaration of Trust, to the extent that they restrict the duties and liabilities of the Administrative Trustees otherwise existing at law or in equity, are agreed by the Depositor and the Securityholders to replace such other duties and liabilities of the Administrative Trustees.

    (b) All payments made by the Property Trustee or a Paying Agent in respect of the Trust Securities shall be made only from the revenue and proceeds from the Trust Property and only to the extent that there shall be sufficient revenue or proceeds from the Trust Property to enable the Property Trustee or a Paying Agent to make payments in accordance with the terms hereof. Each Securityholder, by its acceptance of a Trust Security, agrees that it will look solely to the revenue and proceeds from the Trust Property to the extent legally available for distribution to it as herein provided and that the Trustees are not personally liable to it for any amount distributable in

27

respect of any Trust Security or for any other liability in respect of any Trust Security. This Section 8.1(b) does not limit the liability of the Trustees expressly set forth elsewhere in this Declaration of Trust or, in the case of the Property Trustee, in the Trust Indenture Act.

    (c) No provision of this Declaration of Trust shall be construed to relieve the Property Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that:

     (i) the Property Trustee shall not be liable for any error of judgment made in good faith by an authorized officer of the Property Trustee, unless it shall be proved that the Property Trustee was negligent in ascertaining the pertinent facts;

    (ii) the Property Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of a majority in Liquidation Amount of the Trust Securities relating to the time, method and place of conducting any proceeding for any remedy available to the Property Trustee, or exercising any trust or power conferred upon the Property Trustee under this Declaration of Trust;

    (iii) the Property Trustee's sole duty with respect to the custody, safekeeping and physical preservation of the Debentures and the Payment Account shall be to deal with such property as fiduciary assets, subject to the protections and limitations on liability afforded to the Property Trustee under this Declaration of Trust and the Trust Indenture Act;

    (iv) the Property Trustee shall not be liable for any interest on any money received by it except as it may otherwise agree in writing with the Depositor and money held by the Property Trustee need not be segregated from other funds held by it except in relation to the Payment Account maintained by the Property Trustee pursuant to Section 3.1 and except to the extent otherwise required by law; and

    (v) neither the Property Trustee nor the Administrative Trustees shall be responsible for monitoring each other's compliance or the compliance of the Depositor with their respective duties under this Declaration of Trust, nor shall the Property Trustee or the Administrative Trustees be liable for each other's default or misconduct or that of the Depositor.

SECTION 8.2.  Notice of Defaults.

    (a) Within 90 days after the occurrence of any Event of Default actually known to the Property Trustee, the Property Trustee shall transmit, in the manner and to the extent provided in Section 10.8, notice of such Event of Default to the holders of Preferred Securities, the Administrative Trustees and the Depositor, unless such Event of Default shall have been cured or waived, provided that, except for a default in the payment of principal of (or premium, if any) or interest on any of the Debentures, the Property Trustee shall be protected in withholding such notice if and so long as its board of directors, the executive committee, or a trust committee of directors and/or responsible officers of the Property Trustee in good faith determines that the withholding of such notice is in the interests of the Holders of the Preferred Securities.

    (b) [INTENTIONALLY OMITTED]

    (c) The Holders of a majority in Liquidation Amount of Preferred Securities may, by vote, on behalf of the Holders of all of the Preferred Securities, waive any Event of Default in respect of the Preferred Securities and its consequences, provided that, if the underlying Debenture Event of Default:

     (i) is not waivable under the Indenture, the Event of Default under the Declaration of Trust shall also not be waivable; or

28

    (ii) requires the consent or vote of greater than a majority in principal amount of the holders of the Debentures (a "Super Majority") to be waived under the Indenture, the Event of Default under the Declaration of Trust may only be waived by the vote of the Holders of the same proportion in Liquidation Amount of the Preferred Securities that the relevant Super Majority represents of the aggregate principal amount of the Debentures outstanding.

    The provisions of Section 6.1(b) and this Section 8.2(c) shall be in lieu of Section 316(a)(1)(B) of the Trust Indenture Act and such Section 316(a)(1)(B) of the Trust Indenture Act is hereby expressly excluded from this Declaration of Trust and the Preferred Securities, as permitted by the Trust Indenture Act. Upon such waiver, any such default shall cease to exist, and any Event of Default with respect to the Preferred Securities arising therefrom shall be deemed to have been cured, for every purpose of this Declaration of Trust, but no such waiver shall extend to any subsequent or other default or an Event of Default with respect to the Preferred Securities or impair any right consequent thereon. Any waiver by the Holders of the Preferred Securities of an Event of Default with respect to the Preferred Securities shall also be deemed to constitute a waiver by the Holders of the Common Securities of any such Event of Default with respect to the Common Securities for all purposes of this Declaration of Trust without any further act, vote, or consent of the Holders of the Common Securities.

    (d) The Holders of a majority in Liquidation Amount of the Common Securities may, by vote, on behalf of the Holders of all of the Common Securities, waive any Event of Default with respect to the Common Securities and its consequences, provided that, if the underlying Debenture Event of Default:

     (i) is not waivable under the Indenture, except where the Holders of the Common Securities are deemed to have waived such Event of Default under the Declaration of Trust as provided below in this Section 8.2(d), the Event of Default under the Declaration of Trust shall also not be waivable; or

    (ii) requires the consent or vote of a Super Majority to be waived, except where the Holders of the Common Securities are deemed to have waived such Event of Default under the Declaration of Trust as provided below in this Section 8.2(d), the Event of Default under the Declaration of Trust may only be waived by the vote of the Holders of the same proportion in Liquidation Amount of the Common Securities that the relevant Super Majority represents of the aggregate principal amount of the Debentures outstanding;

provided further, that each Holder of Common Securities will be deemed to have waived any such Event of Default and all Events of Default with respect to the Common Securities and its consequences until all Events of Default with respect to the Preferred Securities have been cured, waived or otherwise eliminated, and until such Events of Default have been so cured, waived or otherwise eliminated, the Property Trustee will be deemed to be acting solely on behalf of the Holders of the Preferred Securities and only the Holders of the Preferred Securities will have the right to direct the Property Trustee in accordance with the terms of the Securities. The provisions of Section 6.1(b) and this Section 8.2(d) shall be in lieu of Section 316(a)(1)(B) of the Trust Indenture Act and such Section 316(a)(1)(B) of the Trust Indenture Act is hereby expressly excluded from this Declaration of Trust and the Preferred Securities, as permitted by the Trust Indenture Act. Subject to the foregoing provisions of this Section 8.2(d), upon such waiver, any such default shall cease to exist and any Event of Default with respect to the Common Securities arising therefrom shall be deemed to have been cured for every purpose of this Declaration of Trust, but no such waiver shall extend to any subsequent or other default or Event of Default with respect to the Common Securities or impair any right consequent thereon.

    (e) A waiver of a Debenture Event of Default under the Indenture by the Property Trustee at the direction of the Holders of the Preferred Securities constitutes a waiver of the

29

corresponding Event of Default under this Declaration of Trust. The foregoing provisions of this Section 8.2(e) shall be in lieu of Section 316(a)(1)(B) of the Trust Indenture Act and such Section 316(a)(1)(B) of the Trust Indenture Act is hereby expressly excluded from this Declaration of Trust and the Preferred Securities, as permitted by the Trust Indenture Act.

    (f)  The Holders of a majority in Liquidation Amount of Preferred Securities will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Property Trustee or to direct the exercise of any trust or power conferred upon the Property Trustee, including the right to direct the Property Trustee to exercise the remedies available to it as holder of the Debentures; provided, however, that the Property Trustee shall have the right to decline to follow any such direction if the Property Trustee shall determine that the action so directed would be unjustly prejudicial to the Holders not taking part in such direction or if the Property Trustee, being advised by counsel, determines that the action or proceeding so directed may not lawfully be taken or if the Property Trustee, in good faith, by its board of directors or trustees, executive committee, or a trust committee of directors or trustees and/or responsible officers, shall determine that the action or proceedings so directed would involve the Property Trustee in personal liability. If the Property Trustee fails to enforce its rights under the Debentures after the Holders of a majority in Liquidation Amount of the Preferred Securities have so directed the Property Trustee, a holder of record of such Preferred Securities may, to the fullest extent permitted by law, institute a legal proceeding against the Depositor to enforce the Property Trustee's rights under the Debentures without first instituting first instituting any legal proceeding against the Property Trustee or any other Person.

    (h) the Property Trustee shall not be bound to make any investigation into the facts or matters stated in any resolutions, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond, debenture, note or other evidence of indebtedness or other paper or document, unless requested in writing to do so by Holders of record of 25% or more of the Preferred Securities (based upon their Liquidation Amount), but the Property Trustee may make such further inquiry or investigation into such facts or matters as it may see fit;

    (i)  the Property Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through its agents or attorneys or an Affiliate, provided that the Property Trustee shall be responsible for its own negligence, recklessness or bad faith with respect to selection of any agent or attorney appointed by it hereunder;

    (a) If an Early Termination Event specified in clause (a), (d) or (e) of Section 9.2 occurs or upon the Expiration Date, the Trust shall be liquidated by the Administrative Trustees and the Property Trustee as expeditiously as the Trustees determine to be possible by distributing, after satisfaction of liabilities to creditors of the Trust as provided by applicable law, to each Securityholder an aggregate principal amount of Debentures equal to the aggregate Liquidation Amount of Trust Securities held by such Holder, subject to paragraphs (d) and (e) of Section 9.4. Notice of liquidation shall be given by the Property Trustee by first-class mail, postage prepaid, mailed not later than 30 nor more than 60 days prior to the Liquidation Date to each Holder of Trust Securities at such Holder's address as it appears in the Securities Register. All notices of liquidation shall:

     (i) state the Liquidation Date;

    (ii) state that, from and after the Liquidation Date, the Trust Securities will no longer be deemed to be Outstanding and any Trust Securities Certificates not surrendered for exchange will be deemed to represent an aggregate principal amount of Debentures equal to the aggregate Liquidation Amount of Preferred Securities held by such Holder; and

    (iii) provide such information with respect to the mechanics by which Holders may exchange Trust Securities Certificates for Debentures, or, if Section 9.4(e) applies, receive a Liquidation Distribution, as the Administrative Trustees or the Property Trustee shall deem appropriate.

    (b) Except where Section 9.4(d) applies, in order to effect the liquidation of the Trust and distribution of the Debentures to Securityholders, the Property Trustee shall establish a record date for such distribution (which shall be not more than 45 days prior to the Liquidation Date) and, either itself acting as exchange agent or through the appointment of a separate exchange agent, shall establish such procedures as it shall deem appropriate to effect the distribution of Debentures in exchange for the Outstanding Trust Securities Certificates.

    (c) Except where Section 9.4(d) applies, after the Liquidation Date, (i) the Trust Securities will no longer be deemed to be Outstanding, (ii) the Clearing Agency or its nominee, as the record holder of such Trust Securities, will receive a registered global certificate or certificates representing the Debentures to be delivered upon such distribution, and (iii) any Trust Securities Certificates not held by the Clearing Agency will be deemed to represent an aggregate principal amount of Debentures equal to the aggregate Liquidation Amount of Preferred Securities held by such Holders, and bearing accrued and unpaid interest in an amount equal to the accrued and unpaid Distributions on such Trust Securities until such certificates are presented to the Property Trustee for transfer or reissuance.

    (d) In the event that, notwithstanding the other provisions of this Section 9.4, whether because of an order for dissolution entered by a court of competent jurisdiction or otherwise, distribution of the Debentures in the manner provided herein is determined by the Property Trustee not to be practicable, the Trust Property shall be liquidated, and the Trust shall be dissolved, wound-up or terminated, by the Property Trustee in such manner as the Property Trustee determines in good faith. In such event, on the date of the dissolution, winding up or other termination of the Trust, Securityholders will be entitled to receive out of the assets of the Trust available for distribution to Securityholders, after satisfaction of liabilities to creditors of the Trust as provided by applicable law, an amount equal to the Liquidation Amount per Trust Security plus accrued and unpaid Distributions thereon to the date of payment (such amount being the "Liquidation Distribution"). If, upon any such dissolution, winding-up or termination, the Liquidation Distribution can be paid only in part because the Trust has insufficient assets available

38

to pay in full the aggregate Liquidation Distribution, then, subject to the next succeeding sentence, the amounts payable by the Trust on the Trust Securities shall be paid on a pro rata basis (based upon Liquidation Amounts). The Holder of the Common Securities will be entitled to receive Liquidation Distributions upon any such dissolution, winding-up or termination pro rata (determined as aforesaid) with Holders of Preferred Securities, except that, if a Debenture Event of Default has occurred and is continuing, the Preferred Securities shall have a priority over the Common Securities.

    (e) Subject to Section 4.4, upon the redemption of the Debentures in whole (but not in part), at maturity, the proceeds from such redemption shall, after satisfaction of liabilities to creditors, be simultaneously applied to redeem Securities having an aggregate Liquidation Amount equal to the aggregate principal amount of the Debentures so redeemed at a redemption price of $50 per Security plus an amount equal to accrued and unpaid Distributions thereon at the date of the repayment, payable in cash.

SECTION 9.5.  Mergers, Consolidations, Amalgamations, Conversions or Replacements of the Trust.  The Trust may not merge with or into, consolidate, amalgamate, convert into, or be replaced by, or convey, transfer or lease its properties and assets substantially as an entirety to any corporation or other Person, except pursuant to this Section 9.5. At the request of the Depositor, with the consent of the Administrative Trustees and without the consent of the Property Trustee, the Delaware Trustee or the Holders of the Preferred Securities, the Trust may merge with or into, consolidate, amalgamate, convert into, be replaced by or convey, transfer or lease its properties and assets substantially as an entirety to a trust organized as such under the laws of any State; provided, that (i) such successor entity either (a) expressly assumes all of the obligations of the Trust with respect to the Preferred Securities or (b) substitutes for the Preferred Securities other securities having substantially the same terms as the Preferred Securities (the "Successor Securities") so long as the Successor Securities rank the same as the Preferred Securities rank in priority with respect to Distributions and payments upon liquidation, redemption and otherwise, (ii) the Depositor expressly appoints a trustee of such successor entity, possessing the same powers and duties as the Property Trustee, as the holder of the Debentures, (iii) the Successor Securities are listed, or any Successor Securities will be listed upon notification of issuance, on any national securities exchange or other organization on which the Preferred Securities are then listed, if any, (iv) such merger, consolidation, amalgamation, conversion, replacement, conveyance, transfer or lease does not cause the Preferred Securities (including any Successor Securities) to be downgraded by any nationally recognized statistical rating organization, (v) such merger, consolidation, amalgamation, conversion, replacement, conveyance, transfer or lease does not adversely affect the rights, preferences and privileges of the Holders of the Preferred Securities (including any Successor Securities) in any material respect, (vi) such successor entity has a purpose substantially identical to that of the Trust, (vii) prior to such merger, consolidation, amalgamation, conversion, replacement, conveyance, transfer or lease the Depositor has received an Opinion of Counsel to the effect that (a) such merger, consolidation, amalgamation, conversion, replacement, conveyance, transfer or lease does not adversely affect the rights, preferences and privileges of the Holders of the Preferred Securities (including any Successor Securities) in any material respect (other than with respect to any dilution of the Holder's interest in the new entity), (b) following such merger, consolidation, amalgamation, conversion, replacement, conveyance, transfer or lease neither the Trust nor such successor entity will be required to register as an "investment company" under the 1940 Act, and (c) following such merger, consolidation, amalgamation, conversion or replacement, the Trust or such successor entity will be treated as a grantor trust for United States federal income tax purposes, and (viii) the Depositor or any permitted successor or assignee owns all of the Common Securities of such successor entity and guarantees the obligations of such successor entity under the Successor Securities at least to the extent provided by the Guarantee. Notwithstanding the foregoing, the Trust shall not, except with the consent of Holders of 100% in aggregate Liquidation Amount of the Preferred Securities, consolidate, amalgamate, convert into, merge with or into, be replaced by or

39

convey, transfer or lease its properties and assets substantially as an entirety to any other entity or permit any other entity to consolidate, amalgamate, convert into, merge with or into, or replace it if such consolidation, amalgamation, conversion, merger, replacement, conveyance, transfer or lease would cause the Trust or the successor entity to be classified as other than a grantor trust for United States federal income tax purposes.

ARTICLE 10

MISCELLANEOUS PROVISIONS

SECTION 10.1.  Limitation of Rights of Securityholders.  The death or incapacity of any person having an interest, beneficial or otherwise, in Trust Securities shall not operate to terminate this Declaration of Trust, nor entitle the legal representatives or heirs of such person or any Securityholder for such person to claim an accounting, take any action or bring any proceeding in any court for a partition or winding-up of the arrangements contemplated hereby, nor otherwise affect the rights, obligations and liabilities of the parties hereto or any of them.

SECTION 10.2.  Amendment.

    (a) This Declaration of Trust may be amended from time to time by the Trustees and the Depositor, without the consent of any Securityholders, (i) to cure any ambiguity, correct or supplement any provision herein which may be inconsistent with any other provision herein, or to make any other provisions with respect to matters or questions arising under this Declaration of Trust, which shall not be inconsistent with the other provisions of this Declaration of Trust, (ii) to modify, eliminate or add to any provisions of this Declaration of Trust to such extent as shall be necessary to ensure that the Trust will be classified for United States federal income tax purposes as a grantor trust at all times that any Trust Securities are Outstanding or to ensure that the Trust will not be required to register as an "investment company" under the 1940 Act, or be classified as other than a grantor trust for United States federal income tax purposes, or (iii) to maintain the qualification of this Declaration of Trust under the Trust Indenture Act; provided, however, that in the case of clause (i), such action shall not adversely affect in any material respect the interests of any Securityholder, and any amendments of this Declaration of Trust shall become effective when notice thereof is given to the Securityholders.

    (b) Except as provided in Section 10.2(c) hereof, any provision of this Declaration of Trust may be amended by the Trustees and the Depositor with (i) the consent of Holders representing not less than a majority (based upon Liquidation Amounts) of the Trust Securities then Outstanding, acting as a single class, and (ii) receipt by the Trustees of an Opinion of Counsel to the effect that such amendment or the exercise of any power granted to the Trustees in accordance with such amendment will not affect the Trust's status as a grantor trust for United States federal income tax purposes or the Trust's not being required to register as an "investment company" under the 1940 Act, provided, however, if any amendment or proposal that would adversely affect the powers, preferences or special rights of the Trust Securities, whether by way of amendment or otherwise, would adversely affect only the Preferred Securities or only the Common Securities, then only the affected class will be entitled to vote on such amendment or proposal and such amendment or proposal shall not be effective except with the approval of a majority in Liquidation Amount of such class of Trust Securities.

    (c) In addition to and notwithstanding any other provision in this Declaration of Trust, without the consent of each affected Securityholder (such consent being obtained in accordance with Section 6.3 or 6.6 hereof), this Declaration of Trust may not be amended to (i) change the amount or timing of any Distribution on the Trust Securities or otherwise adversely affect the amount of any Distribution required to be made in respect of the Trust Securities as of a specified date or (ii) restrict the right of a Securityholder to institute suit for the enforcement of any such

40

payment on or after such date; notwithstanding any other provision herein, without the unanimous consent of the Securityholders (such consent being obtained in accordance with Section 6.3 or 6.6 hereof), this paragraph (c) of this Section 10.2 may not be amended.

    (d) Notwithstanding any other provisions of this Declaration of Trust, no Trustee shall enter into or consent to any amendment to this Declaration of Trust which would cause the Trust to be required to register as an "investment company" under the 1940 Act, or to be classified as other than a grantor trust for United States federal income tax purposes or to reduce or otherwise adversely affect the powers of the Property Trustee.

    (e) Notwithstanding anything in this Declaration of Trust to the contrary, without the consent of the Depositor, this Declaration of Trust may not be amended in a manner which imposes any additional obligation on the Depositor.

    (f)  In the event that any amendment to this Declaration of Trust is made, the Administrative Trustees shall promptly provide to the Depositor a copy of such amendment.

    (g) Neither the Property Trustee nor the Delaware Trustee shall be required to enter into any amendment to this Declaration of Trust which affects its own rights, duties or immunities under this Declaration of Trust.

    (h) The Property Trustee shall be entitled to receive an Opinion of Counsel and an Officers' Certificate stating that any amendment to this Declaration of Trust is in compliance with this Declaration of Trust.

SECTION 10.3.  Separability.  In case any provision in this Declaration of Trust or in the Trust Securities Certificates shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

SECTION 10.4.  Governing Law.  This declaration of trust and the rights and obligations of each of the Securityholders, the trust, and trustees with respect to this declaration of trust in the trust securities shall be construed in accordance with and governed by the internal laws of the state of Delaware.

SECTION 10.5.  Payments Due on Non-Business Day.  If the date fixed for any payment on any Trust Security shall be a day which is not a Business Day, then such payment need not be made on such date but may be made on the next succeeding day which is a Business Day except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as though made on the date fixed for such payment, and no interest shall accrue thereon for the period after such date.

SECTION 10.6.  Successors.  This Declaration of Trust shall be binding upon and shall inure to the benefit of any successor to the Depositor, the Trust or the Relevant Trustee, including any successor by operation of law. Except in connection with a consolidation, merger or sale involving the Depositor that is permitted under Article 8 of the Indenture and pursuant to which the assignee agrees in writing to perform the Depositor's obligations hereunder, the Depositor shall not assign its obligations hereunder.

SECTION 10.7.  Headings.  The Article and Section headings are for convenience only and shall not affect the construction of this Declaration of Trust.

SECTION 10.8.  Reports, Notices and Demands.  Any report, notice, demand or other communication which by any provision of this Declaration of Trust is required or permitted to be given or served to or upon any Securityholder or the Depositor may be given or served in writing by deposit thereof, first-class postage prepaid, in the United States mail, hand delivery or facsimile transmission, in each case, addressed, (a) in the case of a Holder of Preferred Securities, to such Holder as such

Holder's name and address may appear on the Securities Register; and (b) in the case of the Holder of the Common Securities, to Boise Cascade Corporation, 1111 West Jefferson Street, P.O. Box 50, Boise, Idaho 83728-0001, Attention: General Counsel.

    Any notice to Preferred Securityholders shall also be given to such Owners as have, within two years preceding the giving of such notice, filed their names and addresses with the Property Trustee for that purpose. Such notice, demand or other communication to or upon a Securityholder shall be deemed to have been sufficiently given, or made, for all purposes, upon hand delivery, mailing or transmission.

    Any notice, demand or other communication which by any provision of this Declaration of Trust is required or permitted to be given or served to or upon the Trust, the Property Trustee, the Delaware Trustee or the Administrative Trustees shall be given in writing addressed (until another address is published by the Trust) as follows: (a) with respect to the Property Trustee, to BNY Western Trust Company, 601 Union Street, Suite 1720, Seattle, Washington 98101, Attention: Corporate Trust Department, (b) with respect to the Delaware Trustee, to The Bank of New York, (Delaware), White Clay Center, Route 273, Newark, Delaware 19711, Attention: Corporate Trust Department, with a copy of any such notice to the Property Trustee at its address above, and (c) with respect to the Administrative Trustees, to them at the address for notices to the Depositor, marked "Attention: General Counsel." Such notice, demand or other communication to or upon the Trust or the Property Trustee shall be deemed to have been sufficiently given or made only upon actual receipt of the writing by the Trust or the Property Trustee.

SECTION 10.9.  Agreement Not to Petition.  Each of the Trustees and the Depositor agrees for the benefit of the Securityholders that, until at least one year and one day after the Trust has been terminated in accordance with Article 9, it shall not file, or join in the filing of, a petition against the Trust under any bankruptcy, insolvency, reorganization or other similar law (including, without limitation, the United States Bankruptcy Code) (collectively, "Bankruptcy Laws") or otherwise join in the commencement of any proceeding against the Trust under any Bankruptcy Law. In the event the Depositor takes action in violation of this Section 10.9, the Property Trustee agrees, for the benefit of Securityholders, that, at the expense of the Depositor, it shall file an answer with the bankruptcy court or otherwise properly contest the filing of such petition by the Depositor against the Trust or the commencement of such action and raise the defense that the Depositor has agreed in writing not to take such action and should be stopped and precluded therefrom and such other defenses, if any, as counsel for the Trustee or the Trust may assert. The provisions of this Section 10.9 shall survive the termination of this Declaration of Trust.

SECTION 10.10.  Trust Indenture Act; Conflict with Trust Indenture Act.

    (a) This Declaration of Trust is subject to the provisions of the Trust Indenture Act that are required to be part of this Declaration of Trust and shall, to the extent applicable, be governed by such provisions.

    (b) The Property Trustee shall be the only Trustee which is the trustee for the purposes of the Trust Indenture Act.

    (c) If any provision hereof limits, qualifies or conflicts with another provision hereof which is required to be included in this Declaration of Trust by any of the provisions of the Trust Indenture Act, such required provision shall control. If any provision of this Declaration of Trust 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 Declaration of Trust as so modified or to be excluded, as the case may be.

42

    (d) The application of the Trust Indenture Act to this Declaration of Trust shall not affect the nature of the Trust Securities as equity securities representing undivided beneficial interests in the assets of the Trust.

SECTION 10.11.  Acceptance of Terms of Declaration of Trust, Guarantee and Indenture.  The receipt and acceptance of a Trust Security or any interest therein by or on behalf of a Securityholder or beneficial owner, without any signature or further manifestation of assent, shall constitute the unconditional acceptance by the securityholder and all others having a beneficial interest in such Trust Security of all the terms and provisions of this Declaration of Trust and the terms of the Guarantee and the Indenture, and shall constitute the agreement of the Trust, such securityholder and such others that the terms and provisions of this Declaration of Trust shall be binding, operative and effective as to the Trust and such securityholder and such others.

SECTION 10.12.  Counterparts.  This Declaration of Trust may contain more than one counterpart of the signature page and this Declaration of Trust may be executed by the affixing of the signature of each of the Trustees to one of such counterpart signature pages. All of such counterpart signature pages shall be read as though one, and they shall have the same force and effect as though all of the signers had signed a single signature page.

SECTION 10.13.  Purchases of Trust Securities.  Subject to applicable law (including, without limitation, United States federal securities law), the Depositor or its subsidiaries or Affiliates may at any time and from time to time purchase outstanding Preferred Securities by tender, in the open market or by private agreement. Any Preferred Securities so purchased may be cancelled along with a corresponding amount of the Debentures upon surrender of the Preferred Securities Certificates to the Property Trustee (or a reduction in the balance of the Global Certificate).

The right, title and interest of the Guarantee Trustee shall automatically vest in any Successor Guarantee Trustee, upon acceptance by such Successor Guarantee Trustee of its appointment hereunder, and such vesting and cessation of title shall be

4

effective whether or not conveyancing documents have been executed and delivered pursuant to the appointment of such Successor Guarantee Trustee.

    (b) If an Event of Default actually known to the Responsible Officer of the Guarantee Trustee has occurred and is continuing, the Guarantee Trustee shall enforce this Guarantee Agreement for the benefit of the Holders.

    (c) The Guarantee Trustee, before the occurrence of any Event of Default and after the curing of all Events of Default that may have occurred, shall undertake to perform only such duties as are specifically set forth in this Guarantee Agreement, and no implied covenants shall be read into this Guarantee Agreement against the Guarantee Trustee. In case an Event of Default has occurred (that has not been cured or waived pursuant to Section 2.6) and is actually known to the Responsible Officer of the Guarantee Trustee, the Guarantee Trustee shall exercise such of the rights and powers vested in it by this Guarantee Agreement, and use the same degree of care and skill in its exercise thereof, as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs.

    (d) No provision of this Guarantee Agreement shall be construed to relieve the Guarantee Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that:

     (i) prior to the occurrence of any Event of Default and after the curing or waiving of all such Events of Default that may have occurred;

    (A) the duties and obligations of the Guarantee Trustee shall be determined solely by the express provisions of this Guarantee Agreement, and the Guarantee Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Guarantee Agreement; and

    (B) in the absence of bad faith on the part of the Guarantee Trustee, the Guarantee Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Guarantee Trustee and conforming to the requirements of this Guarantee Agreement; but in the case of any such certificates or opinions that by any provision hereof or of the Trust Indenture Act are specifically required to be furnished to the Guarantee Trustee, the Guarantee Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Guarantee Agreement;

    (ii) the Guarantee Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer of the Guarantee Trustee, unless it shall be proved that the Guarantee Trustee was negligent in ascertaining the pertinent facts upon which such judgment was made;

    (iii) the Guarantee Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of not less than a Majority in Liquidation Preference of the Preferred Securities relating to the time, method and place of conducting any proceeding for any remedy available to the Guarantee Trustee, or exercising any trust or power conferred upon the Guarantee Trustee under this Guarantee Agreement; and

    (iv) no provision of this Guarantee Agreement shall require the Guarantee Trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers, if the Guarantee Trustee shall have reasonable grounds for believing that the repayment of such funds or liability is not

5

reasonably assured to it under the terms of this Guarantee Agreement or adequate indemnity against such risk or liability is not reasonably assured to it.

    (iv) The Guarantee Trustee may consult with legal counsel of its selection, and the advice or opinion of such legal counsel with respect to legal matters shall be full and complete authorization and protection in respect of any action taken, suffered or omitted to be taken by it hereunder in good faith and in accordance with such advice or opinion.

    (b) No provision of this Guarantee Agreement shall be deemed to impose any duty or obligation on the Guarantee Trustee to perform any act or acts or exercise any right, power, duty or obligation conferred or imposed on it in any jurisdiction in which it shall be illegal, or in which the Guarantee Trustee shall be unqualified or incompetent in accordance with applicable law, to perform any such act or acts or to exercise any such right, power, duty or obligation.

Upon such separation, the Normal Units will become Stripped Units. Each Stripped Unit will be comprised of (a) a Purchase Contract under which the holder will purchase from the Company not later than the Stock Purchase Date, for $50.00, a number of shares of Common Stock of the Company equal to the Settlement Rate and (b) a ¹/20 undivided beneficial interest in a zero-coupon U.S. Treasury Security (CUSIP No. 912803AB9) maturing on November 15, 2004 that will pay $1,000 on such maturity date (the "Treasury Securities").

    Pursuant to the terms of the Declaration (as defined below), Boise Cascade Trust I, a statutory business trust formed under the laws of the State of Delaware (the "Trust"), will issue 3,000,000 (3,450,000 if the Underwriters' over-allotment option pursuant to the Underwriting Agreement is exercised in full) 7.50% Preferred Securities, (the "Preferred Securities") and 7.50% common securities to the Company (the "Common Securities"), in each case having a stated liquidation value equal to the Stated Amount.

    Pursuant to the terms of the Purchase Contract Agreement and the Purchase Contracts, the Holders, from time to time, of the Units have irrevocably authorized the Purchase Contract Agent, as attorney-in-fact of such Holders, among other things, to execute and deliver this Agreement on behalf of such Holders and to grant the pledge provided hereby of the Preferred Securities, any Treasury Consideration and any Treasury Securities delivered in exchange therefor to secure each Holder's

obligations under the related Purchase Contract, as provided herein and subject to the terms hereof.

PLEDGE; CONTROL AND PERFECTION

    Section 2.1  The Pledge.  The Holders from time to time acting through the Purchase Contract Agent, as their attorney-in-fact, and the Purchase Contract Agent, as such attorney-in-fact, hereby pledge and grant to the Collateral Agent, for the benefit of the Company, as collateral security for the performance when due by such Holders of their respective obligations under the related Purchase Contracts, a security interest in all of the right, title and interest of the Purchase Contract Agent and such Holders (a) in (i) the Preferred Securities, Treasury Consideration and Treasury Securities constituting a part of the Units, (ii) any Treasury Securities delivered in exchange for any Preferred Securities or Treasury Consideration, as applicable, in accordance with Section 4.1 hereof, and (iii) any Preferred Securities or Treasury Consideration, as applicable, delivered in exchange for any Treasury Securities in accordance with Section 4.2 hereof, in each case that have been Transferred to or otherwise received by the Collateral Agent and not released by the Collateral Agent to such Holders under the provisions of this Agreement; (b) in the Collateral Account and all securities, financial assets, security entitlements, cash and other property credited thereto and all Security Entitlements related thereto; (c) in any Senior Debentures delivered to the Collateral Agent upon the occurrence of a liquidation of the Trust as provided in Section 6.2; (d) in the Treasury Consideration purchased on behalf of the Holders of Normal Units by the Collateral Agent upon the occurrence of a Tax Event Redemption as provided in Section 6.2; and (e) all Proceeds of the foregoing (all of the foregoing, collectively, the "Collateral"). Prior to or concurrently with the execution and delivery of this Agreement, the Purchase Contract Agent, on behalf of the initial Holders of the Units, shall cause the Preferred Securities comprising a part of the Normal Units to be Transferred to the Collateral Agent for the benefit of the Company. Such Preferred Securities shall be Transferred by physically delivering such securities to the Securities Intermediary indorsed in blank and causing the Securities Intermediary to credit the Collateral Account with such securities and sending the Collateral Agent a confirmation of the deposit of such securities. Treasury Securities and Treasury Consideration, as applicable, shall be Transferred to the Collateral Account maintained by the Collateral Agent at the Securities Intermediary by book-entry transfer to the Collateral Account in accordance with the TRADES Regulations and other applicable law and by the notation by the Securities Intermediary on its books that a Security

4

Entitlement with respect to such Treasury Securities or Treasury Consideration has been credited to the Collateral Account. For purposes of perfecting the pledge under applicable law, including, to the extent applicable, the TRADES Regulations or the Uniform Commercial Code as adopted and in effect in any applicable jurisdiction, the Collateral Agent shall be the agent of the Company as provided herein. The pledge provided in this Section 2.1 is herein referred to as the "Pledge" and the Preferred Securities (or the Senior Debentures that are delivered pursuant to Section 6.2 hereof), Treasury Consideration or Treasury Securities subject to the Pledge, excluding any Preferred Securities (or the Senior Debentures that are delivered pursuant to Section 6.2 hereof), Treasury Consideration or Treasury Securities released from the Pledge as provided in Sections 4.1 and 4.2 hereof, respectively, are hereinafter referred to as "Pledged Preferred Securities," "Pledged Treasury Consideration" or the "Pledged Treasury Securities," respectively and collectively the "Pledged Securities." Subject to the Pledge and the provisions of Section 2.2 hereof, the Holders from time to time shall have full beneficial ownership of the Collateral. Whenever directed by the Collateral Agent acting on behalf of the Company, the Securities Intermediary shall have the right to reregister the Preferred Securities or any other securities held in physical form in its name.

    Except as may be required in order to release Preferred Securities (or if a Tax Event Redemption has occurred, the Treasury Consideration) or Treasury Securities, as applicable, in connection with a Holder's election to convert its investment from a Normal Unit to a Stripped Unit, or except as otherwise required to release Preferred Securities as specified herein, neither the Collateral Agent, the Custodial Agent nor the Securities Intermediary shall relinquish physical possession of any certificate evidencing a Preferred Security (or if a Tax Event Redemption has occurred, the Treasury Consideration) or Treasury Securities prior to the termination of this Agreement. If it becomes necessary for the Securities Intermediary to relinquish physical possession of a certificate in order to release a portion of the Preferred Securities evidenced thereby from the Pledge, the Securities Intermediary shall use its best efforts to obtain physical possession of a replacement certificate evidencing any Preferred Securities remaining subject to the Pledge hereunder registered to it or endorsed in blank within fifteen days of the date it relinquished possession. The Securities Intermediary shall promptly notify the Company and the Collateral Agent of the Securities Intermediary's failure to obtain possession of any such replacement certificate as required hereby.

    Section 2.2  Control and Perfection.  (a) In connection with the Pledge granted in Section 2.1, and subject to the other provisions of this Agreement, the Holders from time to time acting through the Purchase Contract Agent, as their attorney-in-fact, hereby authorize and direct the Securities Intermediary (without the necessity of obtaining the further consent of the Purchase Contract Agent or any of the Holders), and the Securities Intermediary agrees, to comply with and follow any instructions and entitlement orders (as defined in Section 8-102(a)(8) of the Code) that the Collateral Agent may deliver pursuant to this Agreement or upon the written direction of the Company with respect to the Collateral Account, the Collateral credited thereto and any Security Entitlements with respect to any thereof. In the event the Securities Intermediary receives from the Holders or the Purchase Contract Agent entitlement orders which conflict with entitlement orders received from the Collateral Agent, the Securities Intermediary shall follow the entitlement orders received from the Collateral Agent. Such instructions and entitlement orders may, without limitation, direct the Securities Intermediary to transfer, redeem, assign, or otherwise deliver the Preferred Securities, the Treasury Consideration, the Treasury Securities, and any Security Entitlements with respect thereto or sell, liquidate or dispose of such assets through a broker designated by the Company, and to pay and deliver any income, proceeds or other funds derived therefrom to the Company. The Holders from time to time acting through the Purchase Contract Agent hereby further authorize and direct the Collateral Agent, as agent of the Company, to, upon written direction of the Company, itself issue instructions and entitlement orders, and to otherwise take action, with respect to the Collateral Account, the Collateral credited thereto and any Security Entitlements with respect thereto, pursuant to the terms and provisions hereof, all without the necessity of obtaining the further consent of the Purchase Contract Agent or any of the

5

Holders. The Collateral Agent shall be the agent of the Company and shall act as directed in writing by the Company. Without limiting the generality of the foregoing, the Collateral Agent shall issue entitlement orders to the Securities Intermediary when and as required by the terms hereof or as directed in writing by the Company.

    (b)  The Securities Intermediary hereby confirms and agrees that: (i) all securities or other property underlying any financial assets credited to the Collateral Account shall be registered in the name of the Securities Intermediary, or its nominee, indorsed to the Securities Intermediary, or its nominee, or in blank or credited to another Collateral Account maintained in the name of the Securities Intermediary and in no case will any financial asset credited to the Collateral Account be registered in the name of the Purchase Contract Agent, the Collateral Agent, the Company or any Holder, payable to the order of, or specially indorsed to, the Purchase Contract Agent, the Collateral Agent, the Company or any Holder except to the extent the foregoing have been specially indorsed to the Securities Intermediary or in blank; (ii) all property delivered to the Securities Intermediary pursuant to this Pledge Agreement (including, without limitation, any Preferred Securities, the Treasury Consideration or Treasury Securities) will be promptly credited to the Collateral Account; (iii) the Collateral Account is an account to which financial assets are or may be credited, and the Securities Intermediary shall, subject to the terms of this Agreement, treat the Purchase Contract Agent as entitled to exercise the rights of any financial asset credited to the Collateral Account; (iv) the Securities Intermediary has not entered into, and until the termination of this Agreement will not enter into, any agreement with any other Person relating to the Collateral Account and/or any financial assets credited thereto pursuant to which it has agreed to comply with entitlement orders (as defined in Section 8-102(a)(8) of the Code) of such other Person; and (v) the Securities Intermediary has not entered into, and until the termination of this Agreement will not enter into, any agreement with the Company, the Collateral Agent or the Purchase Contract Agent purporting to limit or condition the obligation of the Securities Intermediary to comply with entitlement orders as set forth in this Section 2.2 hereof.

    (c)  The Securities Intermediary hereby agrees that each item of property (whether investment property, financial asset, security, instrument or cash) credited to the Collateral Account shall be treated as a "financial asset" within the meaning of Section 8-102(a)(9) of the Code.

    (d)  In the event of any conflict between this Agreement (or any portion thereof) and any other agreement now existing or hereafter entered into, the terms of this Agreement shall prevail.

    (e)  The Purchase Contract Agent hereby irrevocably constitutes and appoints the Collateral Agent and the Company, with full power of substitution, as the Purchase Contract Agent's attorney-in-fact to take on behalf of, and in the name, place and stead of, the Purchase Contract Agent and the Holders, any action necessary or desirable to perfect and to keep perfected the security interest in the Collateral referred to in Section 2.1. The grant of such power-of-attorney shall not be deemed to require of the Collateral Agent any specific duties or obligations not otherwise assumed by the Collateral Agent hereunder. Notwithstanding the foregoing, in no event shall the Collateral Agent or Securities Intermediary be responsible for the preparation or filing of any financing or continuation statements in the appropriate jurisdictions or responsible for the maintenance or perfection of any security interest hereunder.

ARTICLE III

DISTRIBUTIONS ON PLEDGED COLLATERAL

    So long as the Purchase Contract Agent is the registered owner of the Pledged Preferred Securities or Pledged Treasury Consideration, it shall receive all payments thereon. If the Pledged Preferred Securities are reregistered, such that the Collateral Agent becomes the registered holder, all payments of the Stated Amount of or cash distributions on the Pledged Preferred Securities and all payments of

6

the principal of, or cash distributions on, any Pledged Treasury Consideration or Pledged Treasury Securities, that are received by the Collateral Agent and that are properly payable hereunder shall be paid by the Collateral Agent by wire transfer in same day funds (provided the Collateral Agent has received payment in same day funds):

     (i) In the case of (A) quarterly cash distributions on Normal Units which include Pledged Preferred Securities or Pledged Treasury Consideration and (B) any payments with respect to any Preferred Securities or Treasury Consideration, as the case may be, that have been released from the Pledge pursuant to Section 4.3 hereof, to the Purchase Contract Agent, for the benefit of the relevant Holders of the Normal Units, to the account designated by the Purchase Contract Agent for such purpose, no later than 2:00 p.m., New York City time, on the Business Day such payment is received by the Collateral Agent (provided that in the event such payment is received by the Collateral Agent on a day that is not a Business Day or after 10:00 a.m., New York City time, on a Business Day, then such payment shall be made no later than 10:30 a.m., New York City time, on the next succeeding Business Day);

    (ii) In the case of any payments with respect to any Treasury Securities that have been released from the Pledge pursuant to Section 4.3 hereof, to the Holders of the Stripped Units to the accounts designated by them in writing for such purpose no later than 2:00 p.m., New York City time, on the Business Day such payment is received by the Collateral Agent (provided that in the event such payment is received by the Collateral Agent on a day that is not a Business Day or after 10 a.m., New York City time, on a Business Day, then such payment shall be made no later than 10:30 a.m., New York City time, on the next succeeding Business Day); and

    (iii) In the case of payments in respect of any Pledged Preferred Securities, Pledged Treasury Consideration or Pledged Treasury Securities, to be paid upon settlement of such Holder's obligations to purchase Common Stock under the Purchase Contract, to the Company on the Stock Purchase Date in accordance with the procedure set forth in Section 4.5(a) or 4.5(b) hereof, in full satisfaction of the respective obligations of the Holders under the related Purchase Contracts.

    All payments received by the Purchase Contract Agent as provided herein shall be applied by the Purchase Contract Agent pursuant to the provisions of the Purchase Contract Agreement. If, notwithstanding the foregoing, the Purchase Contract Agent shall receive any payments of the Stated Amount on account of any Preferred Security or principal of any Treasury Consideration, as applicable, that, at the time of such payment, is a Pledged Preferred Security or Pledged Treasury Consideration, as the case may be, or a Holder of a Stripped Unit shall receive any payments of principal on account of any Treasury Securities that, at the time of such payment, are Pledged Preferred Securities, the Purchase Contract Agent or such Holder shall hold the same as trustee of an express trust for the benefit of the Company (and promptly deliver the same over to the Company) for application to the obligations of the Holders under the related Purchase Contracts, and the Holders shall acquire no right, title or interest in any such payments of Stated Amount or principal so received.

7

multiples of Normal Units such that Treasury Securities to be deposited and the applicable Treasury Consideration to be released are in integral multiples of $1,000, by (a) Transferring to the Collateral Agent Treasury Securities having an aggregate principal amount equal to the aggregate Stated Amount of such Normal Units and (b) delivering such Normal Units to the Purchase Contract Agent, accompanied by a notice, substantially in the form of Exhibit B hereto, to the Purchase Contract Agent stating that such Holder has Transferred Treasury Securities to the Collateral Agent pursuant to clause (a) above (stating the principal amount, the maturities and the CUSIP numbers of the Treasury Securities Transferred by such Holder) and requesting that the Purchase Contract Agent instruct the Collateral Agent to release from the Pledge the Pledged Preferred Securities or Pledged Treasury Consideration, as the case may be, related to such Normal Units, whereupon the Purchase Contract Agent shall promptly give such instruction to the Collateral Agent in the form provided in Exhibit A; provided, however, that if a Tax Event Redemption has occurred and the Treasury Consideration has become a component of the Normal Units, Holders of Normal Units may make such substitution only in integral multiples of $1,000 at any time on or prior to the second Business Day immediately preceding the Stock Purchase Date. Upon receipt of Treasury Securities from a Holder of Normal Units and the related instruction from the Purchase Contract Agent, the Collateral Agent shall release the Pledged Preferred Securities or Pledged Treasury Consideration, as the case may be, and shall promptly Transfer such Pledged Preferred Securities or Pledged Treasury Consideration, as the case may be, free and clear of any lien, pledge or security interest created hereby, to the Purchase Contract Agent. All items Transferred and/or substituted by any Holder pursuant to this Section 4.1, Section 4.2 or any other Section of this Agreement shall be Transferred and/or substituted free and clear of all liens, claims and encumbrances.

    Section 4.2  Substitution for Treasury Securities and the Creation of Normal Units.  At any time (i) on or prior to the fifth Business Day immediately preceding the Stock Purchase Date (unless a Tax Event Redemption has occurred in), a Holder of Stripped Units shall have the right to reestablish Normal Units (a) consisting of the Purchase Contracts and Preferred Securities in integral multiples of 20 Normal Units, or (b) after a remarketing of the Preferred Securities pursuant to the Purchase Contract Agreement, consisting of the Purchase Contracts and the appropriate Treasury Consideration (identified and calculated by reference to the Treasury Consideration then comprising Normal Units) in integral multiples of Stripped Units such that the Treasury Consideration to be deposited and the Treasury Securities to be released are in integral multiples of $1,000, by (x) Transferring to the Collateral Agent Preferred Securities or the appropriate Treasury Consideration, as the case may be, then comprising such number of Normal Units as is equal to such Stripped Units and (y) delivering such Stripped Units to the Purchase Contract Agent, accompanied by a notice, substantially in the form of Exhibit B hereto, to the Purchase Contract Agent stating that such Holder has transferred Preferred Securities or Treasury Consideration to the Collateral Agent pursuant to clause (a) above and requesting that the Purchase Contract Agent instruct the Collateral Agent to release from the Pledge the Pledged Treasury Securities related to such Stripped Units, whereupon the Purchase Contract Agent shall give such instruction to the Collateral Agent in the form provided in Exhibit A; provided, however, that if a Tax Event Redemption has occurred and the Treasury Consideration has become a component of the Normal Units, Holders of Stripped Units may make such substitution only in integral multiples of 20 Stripped Units, at any time on or prior to the second Business Day immediately preceding the Stock Purchase Date; and further provided that Holders of Stripped Units may not reestablish Normal Units during the period beginning on the fourth Business Day prior to any Remarketing Date or Subsequent Remarketing Date, as the case may be, and ending at 5:00 p.m., New York City time, on the third Business Day following such dates. Upon receipt of the Preferred Securities or the appropriate Treasury Consideration, as the case may be, from such Holder and the instruction from the Purchase Contract Agent, the Collateral Agent shall release the Pledged Treasury Securities and shall promptly Transfer such Treasury Securities, free and clear of any lien, pledge or security interest created hereby, to the Purchase Contract Agent.

    Section 4.3  Termination Event.  Upon receipt by the Collateral Agent of written notice from the Company or the Purchase Contract Agent that there has occurred a Termination Event, the Collateral Agent shall release all Collateral from the Pledge and shall promptly Transfer any Pledged Preferred Securities (or the applicable interest in the Treasury Consideration if a Tax Event Redemption has occurred) and Pledged Treasury Securities to the Purchase Contract Agent for the benefit of the Holders of the Normal Units and the Stripped Units, respectively, free and clear of any lien, pledge or security interest or other interest created hereby.

    If such Termination Event shall result from the Company's becoming a debtor under the Bankruptcy Code, and if the Collateral Agent shall for any reason fail promptly to effectuate the release and Transfer of all Pledged Preferred Securities, Pledged Treasury Consideration or of the Pledged Treasury Securities, as the case may be, as provided by this Section 4.3, the Purchase Contract Agent shall (i) use its best efforts to obtain an opinion of a nationally recognized law firm reasonably acceptable to the Collateral Agent to the effect that, as a result of the Company's being the debtor in such a bankruptcy case, the Collateral Agent will not be prohibited from releasing or Transferring the Collateral as provided in this Section 4.3, and shall deliver such opinion to the Collateral Agent within ten days after the occurrence of such Termination Event, and if (y) the Purchase Contract Agent shall be unable to obtain such opinion within ten days after the occurrence of such Termination Event or (z) the Collateral Agent shall continue, after delivery of such opinion, to refuse to effectuate the release and Transfer of all Pledged Preferred Securities, Pledged Treasury Consideration or Pledged Treasury Securities, as the case may be, as provided in this Section 4.3, then the Purchase Contract Agent shall within fifteen days after the occurrence of such Termination Event commence an action or proceeding in the court with jurisdiction of the Company's case under the Bankruptcy Code seeking an order requiring the Collateral Agent to effectuate the release and transfer of all Pledged Preferred Securities, Pledged Treasury Consideration or Pledged Treasury Securities, as the case may be, as provided by this Section 4.3 or (ii) commence an action or proceeding like that described in subsection (i)(z) hereof within ten days after the occurrence of such Termination Event.

    Section 4.4  Early Settlement; Merger Early Settlement.  Upon written notice to the Collateral Agent by the Purchase Contract Agent that one or more Holders of Units have elected to effect Early Settlement or Merger Early Settlement of their respective obligations under the Purchase Contracts forming a part of such Units in accordance with the terms of the Purchase Contracts and the Purchase Contract Agreement (setting forth the number of such Purchase Contracts as to which such Holders have elected to effect Early Settlement or Merger Early Settlement), and that the Purchase Contract Agent has received from such Holders, and paid to the Company as confirmed in writing by the Company, the related Early Settlement Amounts or Merger Early Settlement Amounts, as the case may be, pursuant to the terms of the Purchase Contracts and the Purchase Contract Agreement and that all conditions to such Early Settlement or Merger Early Settlement, as the case may be, have been satisfied, then the Collateral Agent shall release from the Pledge, (a) Pledged Preferred Securities or Pledged Treasury Consideration, as the case may be, in the case of a Holder of Normal Units or (b) Pledged Treasury Securities, in the case of a Holder of Stripped Units, relating to such Purchase Contracts as to which such Holders have elected to effect Early Settlement or Merger Early Settlement, and shall Transfer all such Pledged Preferred Securities, Pledged Treasury Consideration or Pledged Treasury Securities, as the case may be, free and clear of the Pledge created hereby, to the Purchase Contract Agent for the benefit of the Holders.

    Section 4.5  Remarketing; Application of Proceeds; Settlement.  (a) Pursuant to the Purchase Contract Agreement, the Purchase Contract Agent shall notify, by 10:00 a.m., New York City time, on the fourth Business Day immediately preceding September 16, 2004 or any Subsequent Remarketing Date, as the case may be, the Remarketing Agent and the Collateral Agent of the aggregate number of Preferred Securities comprising part of Normal Units to be remarketed. The Collateral Agent shall, by 10:00 a.m., New York City time, on the fourth Business Day immediately preceding September 16, 2004

9

or any Subsequent Remarketing Date, as the case may be, without any instruction from Holders of Normal Units, deliver (i) the Pledged Preferred Securities to be remarketed to the Remarketing Agent for remarketing and (ii) the remaining Pledged Preferred Securities to the Purchase Contract Agent for distribution to the Holders that have elected not to participate in the remarketing in accordance with the Purchase Contract Agreement. On or prior to the third Business Day following the Remarketing Date or Subsequent Remarketing Date, as the case may be, the Remarketing Agent will deliver the Agent-purchased Treasury Consideration (as defined in the Purchase Contract Agreement) purchased from the proceeds of the remarketing to the Purchase Contract Agent, which shall thereupon deliver such Agent-purchased Treasury Consideration to the Collateral Agent. Upon receipt of the Agent-purchased Treasury Consideration from the Purchase Contract Agent following a successful remarketing, the Collateral Agent, for the benefit of the Company, shall thereupon apply such Treasury Consideration to secure such Holders' obligations under the Purchase Contracts. On the Stock Purchase Date, the Collateral Agent shall apply that portion of the payments received in respect of the Pledged Treasury Consideration equal to the aggregate Stated Amount of the related Normal Units to satisfy in full the obligations of such Holders of Normal Units to pay the Purchase Price under the related Purchase Contracts. The remaining portion of such Proceeds, if any, shall be distributed by the Collateral Agent to the Purchase Contract Agent for payment to such Holders.

    Within three Business Days following a Failed Remarketing, the Preferred Securities delivered to the Remarketing Agent and the Purchase Contract Agent pursuant to Section 4.5(a) shall be returned to the Collateral Agent, together with written notice from the Remarketing Agent of the Failed Remarketing. The Collateral Agent, for the benefit of the Company, shall thereupon apply such Preferred Securities to secure the Normal Units Holders' obligations under the Purchase Contracts. If the Remarketing Agent cannot remarket the Preferred Securities on the Remarketing Date, the Remarketing Agent shall use its commercially reasonable best efforts to attempt to remarket Preferred Securities on each of the two Business Days immediately following the Remarketing Date and, if necessary, on each of the three Business Days immediately preceding November 1, 2004, and if necessary, on each of the three Business Days immediately preceding the Stock Purchase Date in accordance with the remarketing procedures described in Section 5.2(b) of the Purchase Contract Agreement and this Pledge Agreement. If by the Stock Purchase Date the Remarketing Agent has failed to remarket the Preferred Securities at 100.5% of the Remarketing Value (as described in the Purchase Contract Agreement), the Remarketing Agent shall advise the Collateral Agent in writing that it cannot remarket the related Pledged Preferred Securities of such Holders of Normal Units. The Collateral Agent, for the benefit of the Company will, at the written direction of the Company, retain or dispose of the Pledged Preferred Securities in accordance with applicable law and satisfy in full, from any such disposition or retention, such Holders' obligations to pay the Purchase Price for the Common Stock; provided, that if upon a Failed Remarketing, the Collateral Agent exercises such rights for the benefit of the Company with respect to such Pledged Preferred Securities, any accumulated and unpaid distributions on such Pledged Preferred Securities will become payable by the Company to the Purchase Contract Agent for payment to the Holder of the Normal Units to which such Pledged Preferred Securities relates in accordance with the Purchase Contract Agreement.

    (b) In the event a Holder of Stripped Units (if a Tax Event Redemption has not occurred) has not made an Early Settlement or Merger Early Settlement of the Purchase Contracts underlying its Stripped Units, such Holder shall be deemed to have elected to pay for the shares of Common Stock to be issued under such Purchase Contracts from the payments received in respect of the related Pledged Treasury Securities. Without receiving any instruction from any such Holder of Stripped Units, the Collateral Agent shall apply such payments to the settlement of such Purchase Contracts on the Stock Purchase Date. In the event the payments received in respect of the related Pledged Treasury Securities are in excess of the aggregate Purchase Price of the Purchase Contracts being settled thereby, the Collateral Agent shall distribute such excess, when received, to the Purchase Contract Agent for the benefit of the Holders.

10

    (c) Pursuant to the Remarketing Agreement, on or prior to the fifth Business Day immediately preceding September 16, 2004, but no earlier than the Payment Date immediately preceding September 16, 2004, holders of Separate Preferred Securities may elect to have their Separate Preferred Securities remarketed by delivering their Separate Preferred Securities, together with a notice of such election, substantially in the form of Exhibit C hereto, to the Custodial Agent. On the fourth Business Day prior to September 16, 2004, by 10:00 a.m., New York City time, the Custodial Agent shall notify the Remarketing Agent of the number of such Separate Preferred Securities to be remarketed. The Custodial Agent will hold such Separate Preferred Securities in an account separate from the Collateral Account. A holder of Separate Preferred Securities electing to have its Separate Preferred Securities remarketed will also have the right to withdraw such election by written notice to the Custodial Agent, substantially in the form of Exhibit D hereto, no later than 5:00 p.m., New York City time, on the fifth Business Day immediately preceding September 16, 2004, and any Subsequent Remarketing Date, upon which notice the Custodial Agent will return such Separate Preferred Securities to such holder. No later than 10:00 a.m., New York City, time on the fourth Business Day immediately preceding September 16, 2004, and any Subsequent Remarketing Date, the Custodial Agent will deliver to the Remarketing Agent for remarketing all Separate Preferred Securities delivered to the Custodial Agent pursuant to this Section 4.5(c) and not withdrawn pursuant to the terms hereof prior to such date. The portion of the proceeds from such remarketing equal to the amount calculated in respect of such Separate Preferred Securities as set forth in Section 5.2(b) of the Purchase Contract Agreement will automatically be remitted by the Remarketing Agent to the Custodial Agent for the benefit of the holders of such Separate Preferred Securities. In addition, after deducting as the remarketing fee an amount not exceeding 25 basis points (.25%) of the total proceeds of such remarketing, the Remarketing Agent will remit to the Custodial Agent the remaining portion of the proceeds, if any, for the benefit of such holders. If, despite using its reasonable best efforts, the Remarketing Agent advises the Custodial Agent in writing that there has been a Failed Remarketing, the Remarketing Agent will promptly return such Preferred Securities to the Custodial Agent for redelivery to such holders. In the event of a dissolution of the Trust and the distribution of the Senior Debentures as described in the Declaration, all references to "Separate Preferred Securities" in this Section 4.5(c) shall be deemed to be references to Senior Debentures which are not pledged hereunder or required to be part of the Collateral.

ARTICLE V

VOTING RIGHTS—PREFERRED SECURITIES

    The Purchase Contract Agent may exercise, or refrain from exercising, any and all voting and other consensual rights pertaining to the Pledged Preferred Securities or any part thereof for any purpose not inconsistent with the terms of this Agreement and in accordance with the terms of the Purchase Contract Agreement; provided, that the Purchase Contract Agent shall not exercise or, as the case may be, shall not refrain from exercising such right if the Company notifies the Purchase Contract Agent in writing that in its judgment such action would impair or otherwise have a material adverse effect on the value of all or any of the Pledged Preferred Securities; and provided, further, that the Purchase Contract Agent shall give the Company and the Collateral Agent at least five days' prior written notice of the manner in which it intends to exercise, or its reasons for refraining from exercising, any such right. Upon receipt of any notices and other communications in respect of any Pledged Preferred Securities, including notice of any meeting at which holders of Preferred Securities are entitled to vote or solicitation of consents, waivers or proxies of holders of Preferred Securities, the Collateral Agent shall use reasonable efforts to send promptly to the Purchase Contract Agent such notice or communication, and as soon as reasonably practicable after receipt of a written request therefor from the Purchase Contract Agent, execute and deliver to the Purchase Contract Agent such proxies and other instruments in respect of such Pledged Preferred Securities (in form and substance

11

satisfactory to the Collateral Agent) as are prepared by the Purchase Contract Agent with respect to the Pledged Preferred Securities.

ARTICLE VI

RIGHTS AND REMEDIES; TAX EVENT REDEMPTION; DISTRIBUTION OF THE SENIOR DEBENTURES

    Section 6.1  Rights and Remedies of the Collateral Agent.  (a) In addition to the rights and remedies available at law or in equity, after an event of default under the Purchase Contract, the Collateral Agent shall have all of the rights and remedies with respect to the Collateral of a secured party under the Uniform Commercial Code (or any successor thereto) as in effect in the State of New York from time to time (the "Code") (whether or not the Code is in effect in the jurisdiction where the rights and remedies are asserted) and the TRADES Regulations and such additional rights and remedies to which a secured party is entitled under the laws in effect in any jurisdiction where any rights and remedies hereunder may be asserted. Wherever reference is made in this Agreement to any section of the Code, such reference shall be deemed to include a reference to any provision of the Code which is a successor to, or amendment of, such section. Without limiting the generality of the foregoing, such remedies may include, to the extent permitted by applicable law, (i) retention of the Pledged Preferred Securities or other Collateral in full satisfaction of the Holders' obligations under the Purchase Contracts or (ii) sale of the Pledged Preferred Securities or other Collateral in one or more public or private sales at the written direction of the Company.

    (b) Without limiting any rights or powers otherwise granted by this Agreement to the Collateral Agent, in the event the Collateral Agent is unable to make payments to the Company on account of any Pledged Treasury Consideration or Pledged Treasury Securities as provided in Article III hereof in satisfaction of the obligations of the Holder of the Units of which such Pledged Treasury Consideration or Pledged Treasury Securities, as applicable, is a part under the related Purchase Contracts, the inability to make such payments shall constitute an event of default hereunder and the Collateral Agent shall have and may exercise, with reference to such Pledged Treasury Securities or such Pledged Treasury Consideration, as applicable, and such obligations of such Holder, any and all of the rights and remedies available to a secured party under the Code and the TRADES Regulations after default by a debtor, and as otherwise granted herein or under any other law.

    (c) Without limiting any rights or powers otherwise granted by this Agreement to the Collateral Agent, the Collateral Agent is hereby irrevocably authorized to receive and collect all payments of (i) the Stated Amount of or, cash distributions on, the Pledged Preferred Securities, or (ii) the principal amount of the Pledged Treasury Consideration or Pledged Treasury Securities, subject, in each case, to the provisions of Article III, and as otherwise granted herein.

    (d) The Purchase Contract Agent, individually and as attorney-in-fact for each Holder of Units, agrees that, from time to time, upon the written request of the Company or the Collateral Agent (acting upon the written request of the Company), the Purchase Contract Agent or such Holder shall execute and deliver such further documents and do such other acts and things as the Company or the Collateral Agent (acting upon the written request of the Company) may reasonably request in order to maintain the Pledge, and the perfection and priority thereof, and to confirm the rights of the Collateral Agent hereunder. The Purchase Contract Agent shall have no liability to any Holder for executing any documents or taking any such acts requested by the Company or the Collateral Agent (acting upon the written request of the Company) hereunder, except for liability for its own negligent act, its own negligent failure to act, its bad faith or its own willful misconduct.

    Section 6.2  Tax Event Redemption.  Upon the occurrence of a Tax Event Redemption prior to (i) a successful remarketing of the Preferred Securities pursuant to the Remarketing Agreement or (ii) the Stock Purchase Date, the Collateral Agent will, upon the written instruction of the Company

12

and the Purchase Contract Agent, deliver the Pledged Preferred Securities to the Property Trustee on behalf of the Purchase Contract Agent for payment of the Redemption Amount. The Collateral Agent shall, or in the event the Pledged Preferred Securities are registered in the name of the Purchase Contract Agent, the Purchase Contract Agent shall, direct the Property Trustee to pay the Redemption Amount therefor payable on the Redemption Date on or prior to 12:30 p.m., New York City time, such Redemption Amount to be paid by check or wire transfer in immediately available funds at such place and at such account as may be designated by the Collateral Agent. In the event the Collateral Agent receives such Redemption Amount, the Collateral Agent will, at the written direction of the Company, apply the Redemption Amount to purchase, from or at the direction of the Quotation Agent, the Redemption Treasury Portfolio and promptly remit the remaining portion of such Redemption Amount to the Purchase Contract Agent for payment to the Holders of Normal Units. The Collateral Agent shall Transfer the Redemption Treasury Portfolio to the Collateral Account in the manner specified herein for Pledged Preferred Securities to secure the obligation of all Holders of Normal Units to purchase Common Stock of the Company under the Purchase Contracts constituting a part of such Normal Units, in substitution for the Pledged Preferred Securities. Thereafter, the Collateral Agent shall have such security interests, rights and obligations with respect to the Treasury Consideration as it had in respect of the Pledged Preferred Securities, as provided in Articles II, III, IV, V and VI and any reference herein to the Pledged Preferred Securities shall be deemed to be a reference to such Treasury Consideration.

    Section 6.3  Distribution of the Senior Debentures.  Upon the occurrence of a voluntary or involuntary dissolution of the Trust, a principal amount of the Senior Debentures constituting the assets of the Trust and underlying the Preferred Securities equal to the aggregate Stated Amount of the Pledged Preferred Securities shall be delivered to the Collateral Agent in exchange for the Pledged Preferred Securities. In the event the Collateral Agent receives such Senior Debentures in respect of Pledged Preferred Securities upon the occurrence of a voluntary or involuntary dissolution of the Trust, the Collateral Agent shall Transfer such Senior Debentures to the Collateral Account in the manner specified herein (including, without limitation, physical delivery thereof as set forth in Section 2.1) for Pledged Preferred Securities to secure the obligations of the Holders of Normal Units to purchase the Company's Common Stock under the related Purchase Contracts. Thereafter, the Collateral Agent shall have such security interests, rights and obligations with respect to such Senior Debentures as it had in respect of the Pledged Preferred Securities as provided in Articles II, III, IV, V and VI hereof, and any reference herein to the Preferred Securities or Pledged Preferred Securities shall be deemed to be referring to such Senior Debentures.

    Section 6.4  Substitutions.  Whenever a Holder has the right to substitute Treasury Securities, Preferred Securities or Treasury Consideration, as the case may be, for Collateral held by the Collateral Agent, such substitution shall not constitute a novation of the security interest created hereby.

ARTICLE VII

REPRESENTATIONS AND WARRANTIES; COVENANTS

    (d) the execution and performance by the Holder of its obligations under this Agreement will not result in the creation of any security interest, lien or other encumbrance on the Collateral other than the security interest and lien granted under Section 2.1 hereof or violate any provision of any existing law or regulation applicable to it or of any mortgage, charge, pledge, indenture, contract or undertaking to which it is a party or which is binding on it or any of its assets.

    Section 7.2  Covenants.  The Holders from time to time, acting through the Purchase Contract Agent as their attorney-in-fact (it being understood that the Purchase Contract Agent shall not be liable for any covenant made by or on behalf of a Holder), hereby covenant to the Collateral Agent that for so long as the Collateral remains subject to the Pledge:

    (a) neither the Purchase Contract Agent nor such Holders will create or purport to create or allow to subsist any mortgage, charge, lien, pledge or any other security interest whatsoever over the Collateral or any part of it other than pursuant to this Agreement; and

    (b) neither the Purchase Contract Agent nor such Holders will sell or otherwise dispose (or attempt to dispose) of the Collateral or any part of it except for the beneficial interest therein, subject to the pledge hereunder, transferred in connection with the Transfer of the Units.

The Collateral Agent and

16

the Custodial Agent shall be entitled to refuse to act until either (i) such conflicting or adverse claims or demands shall have been finally determined by a court of competent jurisdiction or settled by agreement between the conflicting parties as evidenced in a writing, satisfactory to the Collateral Agent or the Custodial Agent, as the case may be, or (ii) the Collateral Agent or the Custodial Agent, as the case may be, shall have received security or an indemnity satisfactory to the Collateral Agent or the Custodial Agent, as the case may be, sufficient to save the Collateral Agent or the Custodial Agent, as the case may be, harmless from and against any and all loss, liability or reasonable out-of-pocket expense which the Collateral Agent or the Custodial Agent, as the case may be, may incur by reason of its acting without bad faith, willful misconduct or gross negligence. The Collateral Agent or the Custodial Agent may in addition elect to commence an interpleader action or seek other judicial relief or orders as the Collateral Agent or the Custodial Agent, as the case may be, may deem necessary. Notwithstanding anything contained herein to the contrary, neither the Collateral Agent nor the Custodial Agent shall be required to take any action that is in its opinion contrary to law or to the terms of this Agreement, or which would in its opinion subject it or any of its officers, employees or directors to liability.

    Section 8.8  Resignation of Collateral Agent.  Subject to the appointment and acceptance of a successor Collateral Agent or Custodial Agent as provided below, (a) the Collateral Agent and the Custodial Agent may resign at any time by giving notice thereof to the Company and the Purchase Contract Agent as attorney-in-fact for the Holders of Units, (b) the Collateral Agent and the Custodial Agent may be removed at any time for any reason by the Company and (c) if the Collateral Agent or the Custodial Agent fails to perform any of its material obligations hereunder in any material respect for a period of not less than 20 days after receiving written notice of such failure by the Purchase Contract Agent and such failure shall be continuing, the Collateral Agent or the Custodial Agent may be removed by the Purchase Contract Agent. The Purchase Contract Agent shall promptly notify the Company of any removal of the Collateral Agent pursuant to clause (c) of the immediately preceding sentence. Upon any such resignation or removal, the Company shall have the right to appoint a successor Collateral Agent or Custodial Agent, as the case may be. If no successor Collateral Agent or Custodial Agent, as the case may be, shall have been so appointed and shall have accepted such appointment within 30 days after the retiring Collateral Agent's or Custodial Agent's giving of notice of resignation or such removal, then the retiring Collateral Agent or Custodial Agent, as the case may be, may at the Company's expense petition any court of competent jurisdiction for the appointment of a successor Collateral Agent or Custodial Agent, as the case may be. Each of the Collateral Agent and the Custodial Agent shall be a bank which has an office in New York, New York with a combined capital and surplus of at least $50,000,000. Upon the acceptance of any appointment as Collateral Agent or Custodial Agent, as the case may be, hereunder by a successor Collateral Agent or Custodial Agent, as the case may be, such successor shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Collateral Agent or Custodial Agent, as the case may be, and the retiring Collateral Agent or Custodial Agent, as the case may be, shall take all appropriate action to transfer any money and property held by it hereunder (including the Collateral) to such successor. The retiring Collateral Agent or Custodial Agent shall, upon such succession, be discharged from its duties and obligations as Collateral Agent or Custodial Agent hereunder. After any retiring Collateral Agent's or Custodial Agent's resignation hereunder as Collateral Agent or Custodial Agent, the provisions of this Section 8.8 shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as the Collateral Agent or Custodial Agent. Any resignation or removal of the Collateral Agent hereunder shall be deemed for all purposes of this Agreement as the simultaneous resignation or removal of the Custodial Agent and the Securities Intermediary.

    Section 8.9  Right to Appoint Agent or Advisor.  The Collateral Agent shall have the right to appoint agents or advisors in connection with any of its duties hereunder, and the Collateral Agent shall not be liable for any action taken or omitted by, or in reliance upon the advice of, such agents or

17

advisors selected in good faith. The appointment of agents (other than legal counsel) pursuant to this Section 8.9 shall be subject to prior consent of the Company, which consent shall not be unreasonably withheld.

    Section 8.10  Survival.  The provisions of this Article VIII shall survive termination of this Agreement and the resignation or removal of the Collateral Agent or the Custodial Agent.

    Section 8.11  Exculpation.  Anything in this Agreement to the contrary notwithstanding, in no event shall any of the Collateral Agent, the Custodial Agent or the Securities Intermediary or their officers, employees or agents be liable under this Agreement to any third party for indirect, special, punitive or consequential loss or damage of any kind whatsoever, including lost profits, whether or not the likelihood of such loss or damage was known to the Collateral Agent, the Custodial Agent or the Securities Intermediary, or any of them, incurred without any act or deed that is found to be attributable to gross negligence, bad faith or willful misconduct on the part of the Collateral Agent, the Custodial Agent or the Securities Intermediary.

ARTICLE IX

AMENDMENT

    Section 9.1  Amendment Without Consent of Holders.  Without the consent of any Holders or the holders of any Separate Preferred Securities, the Company, the Collateral Agent, the Custodial Agent, the Securities Intermediary and the Purchase Contract Agent, at any time and from time to time, may amend this Agreement, in form satisfactory to the Company, the Collateral Agent, the Custodial Agent, the Securities Intermediary and the Purchase Contract Agent, for any of the following purposes:

    (a) to evidence the succession of another Person to the Company, and the assumption by any such successor of the covenants of the Company; or

    (b) to add to the covenants of the Company for the benefit of the Holders, or to surrender any right or power herein conferred upon the Company so long as such covenants or such surrender do not adversely affect the validity, perfection or priority of the security interests granted or created hereunder; or

    (c) to evidence and provide for the acceptance of appointment hereunder by a successor Collateral Agent, Securities Intermediary or Purchase Contract Agent; or

    (d) to cure any ambiguity, to correct or supplement any provisions herein which may be inconsistent with any other such provisions herein, or to make any other provisions with respect to such matters or questions arising under this Agreement, provided such action shall not adversely affect the interests of the Holders.

    Section 9.2  Amendment with Consent of Holders.  With the consent of the Holders of not less than a majority of the Units at the time outstanding, by Act of said Holders delivered to the Company, the Purchase Contract Agent or the Collateral Agent, as the case may be, the Company, when duly authorized, the Purchase Contract Agent, the Collateral Agent, the Custodial Agent and the Securities Intermediary may amend this Agreement for the purpose of modifying in any manner the provisions of this Agreement or the rights of the Holders in respect of the Units; provided, however, that no such supplemental agreement shall, without the consent of the Holder of each Outstanding Unit adversely affected thereby, (a) change the amount or type of Collateral underlying a Unit (except for the rights of holders of Normal Units to substitute the Treasury Securities for the Pledged Preferred Securities or the Pledged Treasury Consideration, as the case may be, or the rights of Holders of Stripped Units to substitute Preferred Securities or the appropriate Treasury Consideration, as applicable, for the Pledged Treasury Securities), impair the right of the Holder of any Unit to receive distributions on the underlying Collateral or otherwise adversely affect the Holder's rights in or to such Collateral; or

18

(b) otherwise effect any action that would require the consent of the Holder of each Outstanding Unit affected thereby pursuant to the Purchase Contract Agreement if such action were effected by an agreement supplemental thereto; or (c) reduce the percentage of Purchase Contracts the consent of whose Holders is required for any such amendment.

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

    Section 9.3  Execution of Amendments.  In executing any amendment permitted by this Article IX, the Collateral Agent, the Custodial Agent, the Securities Intermediary and the Purchase Contract Agent shall receive and (subject to Section 6.1 hereof, with respect to the Collateral Agent, and Section 7.1 of the Purchase Contract Agreement, with respect to the Purchase Contract Agent) shall be fully protected in relying upon, an Opinion of Counsel stating that the execution of such amendment is authorized or permitted by this Agreement and that all conditions precedent, if any, to the execution and delivery of such amendment have been satisfied and, in the case of an amendment pursuant to Section 9.1, that such amendment does not adversely affect the validity, perfection or priority of the security interests granted or created hereunder.

    Section 9.4  Effect of Amendments.  Upon the execution of any amendment under this Article IX, this Agreement shall be modified in accordance therewith, and such amendment shall form a part of this Agreement for all purposes; and every Holder of Units theretofore or thereafter authenticated, executed on behalf of the Holders and delivered under the Purchase Contract Agreement shall be bound thereby.

    Section 9.5  Reference to Amendments.  Unit certificates authenticated, executed on behalf of the Holders and delivered after the execution of any amendment pursuant to this Section may, and shall if required by the Collateral Agent or the Purchase Contract Agent, bear a notation in form approved by the Purchase Contract Agent and the Collateral Agent as to any matter provided for in such amendment. If the Company shall so determine, new Unit certificates so modified as to conform, in the opinion of the Collateral Agent, the Purchase Contract Agent and the Company, to any such amendment may be prepared and executed by the Company and authenticated, executed on behalf of the Holders and delivered by the Purchase Contract Agent in accordance with the Purchase Contract Agreement in exchange for outstanding Unit certificates.
