From time to time, U.S. Bancorp, a Delaware corporation (the “Guarantor”), and each of USB Capital IV (“USB IV”), USB Capital V (“USB V”), USB Capital VI (“USB VI”) or USB Capital VII (“USB VII”), each a statutory business trust formed under the laws of the State of Delaware, may enter into one or more underwriting agreements (each such agreement, an “Underwriting Agreement”) that provide for the sale of designated capital securities to the several underwriters (the “Underwriters”) named therein.

The standard provisions hereof may be incorporated by reference in any Underwriting Agreement. As used herein, the term “Trust” means the statutory business trust named in the first sentence of the Underwriting Agreement. The term “Agreement” means the Underwriting Agreement, including the provisions hereof incorporated therein by reference. Unless otherwise defined herein, all other defined terms have the meanings ascribed thereto in the Underwriting Agreement.

The Guarantor and each of USB IV, USB V, USB VI and USB VII propose that USB IV, USB V, USB VI and USB VII, severally and not jointly, issue from time to time, in one or more series, capital securities (the “Securities”) pursuant to the provisions of the registration statement on Form S-3 filed on July 18, 2001, Registration No. 333-65358. Such Securities may be issued in amounts, at prices and other terms to be determined in light of market conditions at the time of sale. The specific number of the Securities, title and liquidation preference of each Security, issuance price, distribution rate or rates (or method of calculation), distribution periods, distribution payment dates, redemption provisions, and any other specific terms of the Securities shall be set forth in a prospectus supplement.

The Securities specified in Schedule I to the Underwriting Agreement are the “Firm Securities.” If specified in such Underwriting Agreement, the Guarantor and the Trust may grant to the Underwriters the right to purchase at their election an additional number of the Securities specified in such Underwriting Agreement as provided in Article III hereof (the “Optional Securities”). The Firm Securities and the Optional Securities, if any, which the Underwriters elect to purchase pursuant to Article III hereof are herein collectively called the “Offered Securities.”

The Guarantor and USB IV, USB V, USB VI and USB VII have filed with the Securities and Exchange Commission (the “Commission”) a registration statement in respect of the Securities, the Guarantee and the Junior Subordinated Debentures (collectively, the “Registered Securities”), including a prospectus relating to the Registered Securities, and will file with, the

Commission a prospectus supplement specifically relating to the Offered Securities pursuant to Rule 424 under the Securities Act of 1933, as amended (the “Securities Act”). The term “Registration Statement” means the registration statement as amended to the date of the Underwriting Agreement and includes any registration statement filed pursuant to Rule 462(b) under the Securities Act. The term “Basic Prospectus” means a prospectus included in the Registration Statement. The term “Prospectus” means the Basic Prospectus together with the prospectus supplement specifically relating to the Offered Securities (the “Prospectus Supplement”), as filed with, the Commission pursuant to Rule 424. The term “preliminary prospectus” means a preliminary prospectus supplement specifically relating to the Offered Securities together with the Basic Prospectus. As used herein, the terms “Registration Statement,” “Basic Prospectus,” “Prospectus” and “preliminary prospectus” shall include in each case the material, if any, incorporated by reference therein as of its effective time, in the case of the Registration Statement, and as of the date of such prospectus, in the case of any Basic Prospectus, Prospectus or preliminary prospectus. Any reference to any amendment or supplement to any Basic Prospectus, Prospectus or preliminary prospectus shall be deemed to refer to and include any document incorporated by reference after the date of such Basic Prospectus, Prospectus or preliminary prospectus, as the case may be. Any reference to any amendment to the Registration Statement shall be deemed to include any document incorporated by reference after the effective time of such Registration Statement.

The terms of the public offering of the Firm Securities are set forth in the Prospectus.

III

The Guarantor and the Trust may specify in the Underwriting Agreement applicable to any Securities that the Guarantor and the Trust thereby grant to the Underwriters the right (an “Overallotment Option”) to purchase at their election up to the number of Optional Shares set forth in such Underwriting Agreement, on the terms set forth in the Underwriting Agreement, for the sole purpose of covering over-allotments in the sale of the Firm Securities. Any such election to purchase Optional Securities may be exercised by written notice from each of the Representatives (as defined in the Underwriting Agreement) to the Guarantor and the Trust, given within a period specified in the Underwriting Agreement, setting forth the aggregate number of Optional Securities to be purchased and the date on which such Optional Securities are to be delivered, as determined by the Representatives but in no event earlier than the first Closing Date or, unless the Representatives, the Guarantor and the Trust otherwise agree in writing, earlier than or later than the respective number of business days after the date of such notice set forth in such Underwriting Agreement.

The number of Optional Securities to be added to the number of Firm Securities to be purchased by each Underwriter as set forth in Schedule I to the Underwriting Agreement applicable to such Securities shall be, in each case, the number of Optional Securities which the Guarantor has been advised by the Representatives have been attributed to such Underwriter; provided, that, if the Guarantor and the Trust have not been so advised, the number of Optional Securities to be so added shall be, in each case, that proportion of Optional Securities which the

number of Firm Securities to be purchased by such Underwriter under such Underwriting Agreement bears to the aggregate number of Firm Securities (rounded as the Representatives may determine to the nearest 10 shares). The total number of Offered Securities to be purchased by all Underwriters pursuant to such Underwriting Agreement shall be the aggregate number of Firm Securities set forth in Schedule I to such Underwriting Agreement plus the aggregate number of Optional Securities which the Underwriters elect to purchase.

Payment for the Securities shall be made in federal (same day) funds at the time, date and place set forth in the Underwriting Agreement, upon delivery to the Representatives, through the facilities of The Depository Trust Company (“DTC”), for the respective accounts of the several Underwriters of the Securities. Each time and date of such payment and delivery of the Securities, including any payment and delivery pursuant to the exercise of the Overallotment Option by the Underwriters, is herein referred to as a “Closing Date.” The Trust will cause the certificates representing the Securities to be made available for checking and packaging at least one day prior to the Closing Date at the office of DTC or its designated custodian.

The several obligations of the Underwriters hereunder are subject to the condition that all representations and warranties and other statements of the Guarantor and the Trust in or incorporated by reference in the Underwriting Agreement are, at and as of each Closing Date, true and correct, the condition that the Guarantor and the Trust shall have performed all of their respective obligations hereunder theretofore to be performed, and to the following additional conditions:

VIII

(a) The Guarantor and the Trust agree, jointly and severally, to indemnify and hold harmless each Underwriter and each person, if any, who controls such Underwriter (each an “Indemnified Person”) within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or supplement thereto or any related preliminary prospectus or preliminary prospectus supplement) or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, unless such untrue statement or omission was made in reliance upon and in conformity with written information relating to such Indemnified Person furnished to the Guarantor or the Trust by the Representatives expressly for use in the Registration Statement (or any amendment thereto) or the Prospectus (or any amendment or supplement thereto or any related preliminary prospectus or preliminary prospectus supplement);

(ii) against any and all loss, liability, claim, damage and expense whatsoever to the extent of the aggregate amount paid in settlement of any litigation, or investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission (except as made in reliance upon and in conformity with information relating to such Indemnified Person furnished by the Representatives as aforesaid) if such settlement is effected with the written consent of the Guarantor or the Trust (which consent shall not be unreasonably withheld or delayed); and

(iii) against any and all expense whatsoever (including the fees and disbursements of counsel chosen by such Indemnified Person), as incurred, reasonably incurred in investigating, preparing or defending against any litigation, or investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission (except as made in reliance upon and in conformity with information relating to such Indemnified Person furnished by the Representatives as aforesaid), to the extent that any such expense is not paid under (i) or (ii) above.

(b) Each Underwriter, severally and not jointly, will indemnify and hold harmless the Guarantor and the Trust, each of their respective directors or trustees, each of their officers who

signed the Registration Statement, and each person, if any, who controls the Guarantor or the Trust within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto) or the Prospectus (or any amendment or supplement thereto or any related preliminary prospectus or preliminary prospectus supplement) in reliance upon and in conformity with written information relating to such Underwriter furnished to the Guarantor or the Trust by the Representatives expressly for use in the Registration Statement (or any amendment thereto) or the Prospectus (or any amendment or supplement thereto or any related preliminary prospectus or preliminary prospectus supplement).

(c) Each indemnified party shall give prompt notice to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder but failure to so notify an indemnifying party shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. An indemnifying party may participate at its own expense in the defense of such action. In no event shall the indemnifying parties be liable for the fees and expenses of more than one counsel (in addition to any local counsel) for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances; provided, however, that when more than one of the Underwriters is an indemnified party each such Underwriter shall be entitled to separate counsel (in addition to any local counsel) in each such jurisdiction to the extent such Underwriter may have interests conflicting with those of the other Underwriter or Underwriters because of the participation of one Underwriter in a transaction hereunder in which the other Underwriter or Underwriters did not participate. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(d) In order to provide for just and equitable contribution in circumstances in which the indemnity agreement provided for in this Section VIII is for any reason held to be unavailable to the Underwriters in accordance with its terms, the Guarantor, the Trust and the Underwriters shall contribute to the aggregate losses, liabilities, claims, damages and expenses of the nature contemplated by said indemnity agreement incurred by the Guarantor and the Trust on the one hand and the Underwriters on the other with respect to Securities sold to the Underwriters in such proportions as is appropriate to reflect the relative benefits received by the Guarantor and the Trust on the one hand and the Underwriters on the other. The relative benefits received by the Guarantor and the Trust on the one hand and the Underwriters on the other shall be deemed to be in such proportion represented by the percentage that the total commissions and underwriting discounts received by the Underwriters to the date of such liability bears to the total sales price (before deducting expenses) received by the Trust from the sale of the Offered Securities made to the Underwriters to the date of such liability, and the Guarantor and the Trust are responsible for the balance. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the Underwriters failed to give the

notice required under (c), then the Guarantor and the Trust on the one hand and the Underwriters on the other shall contribute to such aggregate losses, liabilities, claims, damages and expenses in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Guarantor and the Trust on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such liabilities, claims, damages and expenses, as well as any other relevant equitable considerations. 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 Guarantor and the Trust or the Representatives and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Guarantor, the Trust and the Underwriters agree that it would not be just and equitable if contributions pursuant to this paragraph were determined pro rata (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 in this paragraph. Notwithstanding the provisions of this paragraph, the Underwriters shall not be required to contribute any amount in excess of the amount by which the total price at which the Securities referred to in the second sentence of this paragraph that were offered and sold to the public through the Underwriters exceeds the amount of any damages that the Underwriters have 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 under this paragraph to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section, each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Underwriter, and each director of the Guarantor, each trustee of the Trust, each officer of the Guarantor and the Trust who signed the Registration Statement, and each person, if any, who controls the Guarantor or the Trust within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Guarantor and the Trust.

The indemnity and contribution agreements contained in Section VIII hereof and the representations and warranties of the Guarantor and the Trust in this Agreement or in any certificate submitted pursuant hereto shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by any Underwriter or on behalf of any Underwriter or any person controlling any Underwriter or by or on behalf of the Guarantor and the Trust or each of their respective directors or trustees or each of their officers or any person controlling the Guarantor and the Trust and (iii) acceptance of any payment for any of the Offered Securities, if any.

If any Underwriter shall default in its obligation to purchase the Offered Securities, which it has agreed to purchase hereunder, the Representatives may in their discretion arrange for themselves or another party or other parties to purchase such Offered Securities on the terms

contained herein. If within thirty-six hours after such default by any Underwriter the Representatives do not arrange for the purchase of such Offered Securities then the Guarantor and the Trust shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to the Representatives to purchase such Offered Securities on such terms. In the event that, within the respective prescribed period, the Representatives notify the Guarantor and the Trust that they have so arranged for the purchase of such Offered Securities or the Guarantor or the Trust notify the Representatives that it has so arranged for the purchase of such Offered Securities, the Representatives, the Guarantor or the Trust shall have the right to postpone the Closing Date 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 Guarantor and the Trust agree to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in the reasonable opinion of the Representatives may thereby be made necessary. The term “Underwriters” as used in this Agreement shall include any person substituted under this Section X with like effect as if such person had originally been a party to this Agreement with respect to such Offered Securities.

If, after giving effect to any arrangements for the purchase of the Offered Securities of a defaulting Underwriter or Underwriters by the Representatives and the Guarantor and the Trust as provided in the immediately preceding paragraph hereof, the aggregate principal amount of such Offered Securities which remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Offered Securities then the Guarantor and the Trust shall have the right to require each non-defaulting Underwriter to purchase the Offered Securities which such Underwriter agreed to purchase hereunder and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the principal amount of Offered Securities which such Underwriter agreed to purchase hereunder) of the Offered 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.

If, after giving effect to any arrangements for the purchase of the Offered Securities of a defaulting Underwriter or Underwriters by the Representatives and the Guarantor and the Trust as provided in the first paragraph of this Section X, the aggregate principal amount of Offered Securities which remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Offered Securities or if the Guarantor and the Trust shall not exercise the right described in the immediately preceding paragraph to require non-defaulting Underwriters to purchase Offered Securities of a defaulting Underwriter or Underwriters, then this Agreement shall thereupon terminate, without liability on the part of any non-defaulting Underwriters, the Guarantor or the Trust, except for the expenses to be borne by the Guarantor, the Trust and the Underwriters as provided in Section XI hereof and the indemnity and contribution agreements in Section VIII hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

The Guarantor covenants and agrees with the several Underwriters that the Guarantor will pay or cause to be paid the following: (i) the fees, disbursements and expenses of the

Guarantor’s and the Trust’s counsel and accountants in connection with the registration of the Securities under the Securities Act and all other expenses in connection with the preparation, printing and filing of the Registration Statement and the Prospectus and amendments and supplements thereto and the mailing and delivering of copies thereof to the Underwriters and to dealers; (ii) the cost of printing this Agreement and any Blue Sky and legal investment memoranda; (iii) all expenses in connection with the qualification of the Offered Securities for offering and sale under state securities laws as provided in Section VI hereof, including the fees and disbursements of counsel in connection with such qualification and in connection with the preparation of any Blue Sky memorandum or any Blue Sky and legal investment surveys; (iv) any fees charged by securities rating services for rating the Securities; (v) the cost of preparing the Securities; (vi) the fees and expenses of the Trustee and any agent of the Trustee and the fees and disbursements of counsel for the Trustee in connection with the Indenture, the Trust Agreement and the Securities; (vii) the fees and expenses incident to any Overallotment Options which are not otherwise specifically provided for in this section; and (viii) all other costs and expenses incident to the performance of its obligations hereunder which are not otherwise specifically provided for in this Section XI. It is understood, however, that, except as provided in this Section XI and Sections VIII and XII hereof, the Underwriters will pay all of their own costs and expenses, including the fees of their counsel, transfer taxes on resale of any of the Offered Securities by them and any advertising expenses connected with any offers they may make.

XII

If the Underwriting Agreement shall be terminated by the Underwriters or any of them, because of any failure or refusal on the part of the Guarantor or the Trust to comply with the terms or to fulfill any of the conditions of the Underwriting Agreement, or if for any reason the Guarantor or the Trust shall be unable to perform its obligations under the Underwriting Agreement except pursuant to Article X hereof, the Guarantor will reimburse the Underwriters or such Underwriters as have so terminated the Underwriting Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with the Offered Securities.

XIII

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

All statements, requests, notices and agreements hereunder shall be in writing or by telegram if promptly confirmed in writing, and if to the Underwriters shall be sufficient in all respects if delivered or sent by registered mail to the address of the principal offices of the Representatives and if to the Guarantor or the Trust shall be sufficient in all respects if delivered or sent by registered mail to the address of the Guarantor set forth in the Underwriting Agreement, Attention: Treasurer; provided, however, that any notice to an Underwriter pursuant

to Section VIII hereof shall be delivered or sent by registered mail to such Underwriter at its address set forth in its Underwriters’ Questionnaire, or telex constituting such Underwriters’ Questionnaire, which address will be supplied to the Guarantor by the Representatives upon request.

XIV

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

Time shall be of the essence of this Agreement.

This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

This Agreement and the rights and obligations of the parties created hereby shall be governed by the laws of the State of New York.
