If the firm or firms listed in Schedule II hereto include only the firm or firms listed in Schedule I hereto, then the terms “Underwriters” and “Representative”, as used herein, shall each be deemed to refer to such firm or firms.

The Normal PPS will be guaranteed (the “Guarantee”) by ▇▇▇▇▇ Fargo & Company, a Delaware corporation (“▇▇▇▇▇ Fargo” or the “Guarantor”), to the extent described in a Guarantee Agreement to be dated as of May 19, 2008 (the “Guarantee Agreement”) between the Guarantor and The Bank of New York Trust Company, N.A., as trustee (the “Guarantee Trustee”). The Trust will use the proceeds from the sale of the Normal PPS and the sale of the Trust Common Securities (as defined below) pursuant to the Note Purchase Agreement to be dated as of May 19, 2008 between the Trust and the Guarantor (the “Note Purchase Agreement”), to purchase from the Guarantor $2,500,100,000 aggregate principal amount of its Remarketable 7.50% Junior Subordinated Notes due 2044 (the “Notes”) to be issued under an Indenture dated as of August 1, 2005 between the Guarantor and The Bank of New York Trust Company, N.A.

The Trust will contemporaneously enter into (i) a Stock Purchase Contract Agreement (the “Stock Purchase Contract Agreement”) with the Guarantor, pursuant to which the Trust will agree to purchase 25,001 Stock Purchase Contracts (each a “Stock Purchase Contract”), each having a stated amount of $100,000 and obligating the Trust to purchase from the Guarantor, and the Guarantor to sell to the Trust, subject to the terms thereof, one share of the Guarantor’s Non-Cumulative Perpetual Preferred Stock, Series A, $100,000 liquidation preference per share (the “Preferred Stock”), on the Stock Purchase Date provided for (and as defined) in the Stock Purchase Contract Agreement, and (ii) a Collateral Agreement (the “Collateral Agreement”) with Wilmington Trust Company, as collateral agent (the “ Collateral Agent “), registrar and transfer agent (the “Transfer Agent”) and custodial agent (the “Custodial Agent”), under which the Trust will initially pledge the Notes to secure its obligation to purchase Preferred Stock under the Stock Purchase Contracts.

The Trust was created under Delaware law pursuant to a Declaration of Trust and Trust Agreement dated as of April 22, 2004 executed by ▇▇▇▇▇ Fargo, as depositor, and by ▇▇▇▇▇▇▇ ▇. ▇▇▇▇ and ▇▇▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇, as administrative trustees of the Trust and by Wilmington Trust Company, as Delaware trustee (the “Delaware Trustee”), as amended by the Amended and Restated Declaration of Trust and Trust Agreement (the “Trust Agreement”) among ▇▇▇▇▇ Fargo, the administrative trustees named therein (the “Administrative Trustees”), the Delaware Trustee and the property trustee named therein (the “Property Trustee”) to be dated as of May 19, 2008.

1. Representations and Warranties.

Each of the Trust and the Guarantor jointly and severally represent and warrant to, and agree with, each Underwriter that:

(a) The Trust and the Guarantor meet the requirements for use of Form S-3 under the Securities Act of 1933, as amended (the “Act”“) and have filed with the Securities and Exchange Commission (the “Commission”) an automatic shelf registration statement on such Form as defined in Rule 405 under the Act (the file number of which is set forth in Schedule I hereto) for the registration under the Act of the Normal PPS and the related securities (including the Capital PPS, the Stripped PPS, the Notes, the Guarantee, the Stock Purchase Contracts and the Preferred Stock (collectively, the “Related Securities”)). Such registration statement, including any amendments thereto, became effective upon filing. The Trust and the Guarantor propose to file with the Commission pursuant to Rule 424 under the Act a supplement to the form of prospectus included in such registration statement relating to the Normal PPS and the Related Securities in substantially the form heretofore delivered to you. Such registration statement, including all exhibits thereto (but excluding the Statements of Eligibility on Form T-1), as amended at the date of this Agreement, and including any prospectus

supplement relating to the Normal PPS and the Related Securities that is filed with the Commission pursuant to Rule 424(b) under the Act and deemed part of such registration statement pursuant to Rule 430B under the Act, is hereinafter called the “Registration Statement”; such prospectus relating to the Normal PPS and the Related Securities in the form in which it appears in the Registration Statement is hereinafter called the “Basic Prospectus” and such supplemented form of prospectus, in the form in which it shall be filed with the Commission pursuant to Rule 424(b) (including the Basic Prospectus as so supplemented) is hereinafter called the “Final Prospectus”. Any preliminary form of the Final Prospectus which has been or will be filed pursuant to Rule 424 is hereinafter called the “Preliminary Final Prospectus”. Any reference herein to the Registration Statement, the Basic Prospectus, any Preliminary Final Prospectus or the Final Prospectus shall be deemed to refer to and include the documents incorporated by reference therein, pursuant to Item 12 of Form S-3, which were filed under the Securities Exchange Act of 1934 (the “Exchange Act”) on or before the date of this Agreement, or the issue date of the Basic Prospectus, any Preliminary Final Prospectus or the Final Prospectus, as the case may be; and any reference herein to the terms “amend”, “amendment” or “supplement” with respect to the Registration Statement, the Basic Prospectus, any Preliminary Final Prospectus or the Final Prospectus shall be deemed to refer to and include the filing of any document under the Exchange Act after the date of this Agreement, or the issue date of the Basic Prospectus, any Preliminary Final Prospectus or the Final Prospectus, as the case may be, and deemed to be incorporated therein by reference.

(b) As of the date hereof, when the Final Prospectus is first filed pursuant to Rule 424(b) under the Act, when, prior to the Closing Date (as hereinafter defined), any amendment to the Registration Statement becomes effective (including the filing of any document incorporated by reference in the Registration Statement), when any supplement to the Final Prospectus is filed with the Commission and at the Closing Date (as hereinafter defined), (i) the Registration Statement, as amended as of any such time, and the Final Prospectus, as amended or supplemented as of any such time, the Indenture, the Trust Agreement and the Guarantee Agreement will comply in all material respects with the applicable requirements of the Act, the Trust Indenture Act of 1939 (the “Trust Indenture Act”) and the Exchange Act and the respective rules thereunder and (ii) neither the Registration Statement, as amended as of any such time, nor the Final Prospectus, as amended or supplemented as of any such time, will contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading; provided, however, that the Trust and the Guarantor make no representations or warranties as to (i) that part of the Registration Statement which shall constitute the Statements of Eligibility on Form T-1 under the Trust Indenture Act of the Note Trustee, the Guarantee Trustee and the Property Trustee, or (ii) the information contained in or omitted from the Registration Statement or the Final Prospectus or any amendment thereof or supplement thereto in reliance upon and in conformity with information furnished in writing

to the Trust or the Guarantor by or on behalf of any Underwriter through the Representative specifically for use in connection with the preparation of the Registration Statement and the Final Prospectus (it being understood and agreed that the only such information contained in the Registration Statement or Final Prospectus furnished by any Underwriter consists of such information described as such in a letter dated the Closing Date the (“Blood Letter”) delivered by the Representative to the Trust and the Guarantor).

(c) At the Applicable Time, the Disclosure Package does not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from the Disclosure Package based upon and in conformity with written information furnished to the Trust or the Guarantor by any Underwriter through the Representative specifically for use therein, it being understood and agreed that the only such information furnished by or on behalf of any Underwriter consists of the information described as such in the Blood Letter.

(d)(i) At the time of filing the Registration Statement, (ii) at the time of the most recent amendment thereto for the purposes of complying with Section 10(a)(3) of the Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Sections 13 or 15(d) of the Exchange Act or form of prospectus) and (iii) at the time the Trust or the Guarantor or any person acting on their behalf (within the meaning, for this clause only, of Rule 163(c) under the Act) made any offer relating to the Normal PPS and the Related Securities in reliance on the exemption in Rule 163 under the Act, the Trust and the Guarantor were or are (as the case may be) each a “well-known seasoned issuer” as defined in Rule 405 under the Act. The Guarantor agrees to pay the fees required by the Commission relating to the Normal PPS and the Related Securities within the time required by Rule 456(b)(1) under the Act without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r) under the Act.

(e) At the earliest time after the filing of the Registration Statement that the Trust, the Guarantor or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2) under the Act) of the Normal PPS and the Related Securities, each of the Trust and the Guarantor was not and is not an Ineligible Issuer (as defined in Rule 405 under the Act), without taking account of any determination by the Commission pursuant to Rule 405 that it is not necessary that the Trust and the Guarantor be considered an Ineligible Issuer.

(f) Each Issuer Free Writing Prospectus does not include any information that conflicts with the information contained in the Registration Statement, including any document incorporated therein and any prospectus supplement deemed to be a part thereof that has not been superseded or modified. The foregoing sentence does not apply to statements in or omissions from any Issuer Free Writing Prospectus based upon and in conformity with written

information furnished to the Trust or the Guarantor by any Underwriter through the Representative specifically for use therein, it being understood and agreed that the only such information furnished by or on behalf of any Underwriter consists of the information described as such in the Blood Letter.

(g) The provisions of the Collateral Agreement are effective to create in favor of the Collateral Agent for the benefit of the Guarantor a valid security interest under the Uniform Commercial Code as in effect in the State of New York on the date hereof (the “UCC”) in all “security entitlements” (as defined in Section 8-102(a)(17) of the UCC and the Federal Book-Entry Regulations) with respect to those Notes (other than the Notes excluded from the definition of “Collateral” in the Collateral Agreement) or treasury securities included in the collateral account established pursuant to the Collateral Agreement (the “Pledged Securities Entitlements”); and the provisions of the Collateral Agreement are effective under the UCC and the Federal Book-Entry Regulations to perfect the security interest of the Collateral Agent for the benefit of the Guarantor in the Pledged Security Entitlements.

(d) If, at any time when a prospectus relating to the Normal PPS and the Related Securities is required to be delivered under the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172 under the Act), any event occurs as a result of which the Final Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made not misleading, or if it shall be necessary to amend or supplement the Final Prospectus to comply with the Act or the Exchange Act or the respective rules thereunder, including in connection with the use or delivery of the Final Prospectus, the Trust or the Guarantor will promptly notify you and, upon your request, the Trust and the Guarantor will prepare and file with the Commission an amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance.

The Guarantor will pay the expenses of printing or other production of all documents relating to the offering and the expenses incurred in distributing the Final Prospectus to the Underwriters.

(g) The Trust and the Guarantor will arrange for the qualification of the Normal PPS and the Related Securities for sale under the laws of such jurisdictions as the Representative may designate and will maintain such qualifications in effect so long as required to complete the distribution of the Normal PPS; provided, however, that each of the Trust and the Guarantor shall not be required to qualify to do business in any jurisdiction where it is not now so qualified or to take any action which would subject it to general or unlimited service of process in any jurisdiction where it is not now so subject or subject itself to taxation in any jurisdiction where it is not now so subject.

In the event the Notes are distributed to the holders of the Normal PPS, the Trust and the Guarantor agree to use all commercially reasonable efforts to obtain and maintain the listing of the Notes on the New York Stock Exchange or any other stock exchange on which the Normal PPS are then listed until such time as none of the Notes are outstanding.

(j) The Trust and the Guarantor each agree that, unless it obtains the prior written consent of the Representative, and each Underwriter, severally and not jointly, agrees with the Trust and the Guarantor that, unless it has obtained or will obtain, as the case may be, the prior written consent of the Trust and the Guarantor, it has not made and will not make any offer relating to the Normal PPS and the Related Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a Free Writing Prospectus required to be filed with the Commission or retained by the Trust or the Guarantor under Rule 433 under the Act; provided that the prior written consent of the parties hereto shall be deemed to have been given in respect of the Free Writing Prospectuses included in Schedule III hereto. Any such Free Writing Prospectus consented to by the Representative or the Trust and the Guarantor is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Trust and the Guarantor each agree that (A) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (B) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 under the Act applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.

7. Indemnification and Contribution.

(a) The Trust and the Guarantor jointly and severally agree to indemnify and hold harmless each Underwriter and each person who controls any Underwriter within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement for the registration of the Normal PPS and the Related Securities as originally filed or in any amendment thereof, or in the Basic Prospectus, any Preliminary Final Prospectus, the Final Prospectus, any Issuer Free Writing Prospectus or in any amendment thereof 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 agrees to reimburse each such indemnified party to the extent set forth below, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Trust and the Guarantor will 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 any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Trust or the Guarantor by or on behalf of any Underwriter through the Representative specifically for use therein (it being understood and agreed that the only such information furnished by any Underwriter consists of such information described as such in the Blood Letter). This indemnity agreement will be in addition to any liability which the Trust or the Guarantor may otherwise have.

(b) Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless the Trust, the Administrative Trustees, the Guarantor, each of their directors, each of the Guarantor’s officers and the Trust’s representative who signs the Registration Statement, and each person who controls the Trust or the Guarantor within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Trust and the Guarantor to each Underwriter, but only with reference to written information relating to such Underwriter furnished to the Trust or the Guarantor by or on behalf of such Underwriter through the Representative for use in the preparation of the documents referred to in the foregoing indemnity (it being understood and agreed that the only such information furnished by any Underwriter consists of such information described as such in the Blood Letter). This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have.

(c) Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any action (including any governmental investigation), such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 7, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party otherwise than under this Section 7. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will 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 reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party). In any such proceeding, any indemnified party shall have the right to obtain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnified party and the indemnifying party and representation of both parties by the same counsel would be inappropriate due to actual or potential conflicts of interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate identified firm (in addition to any identified local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by the Representative in the case of parties to be indemnified pursuant to paragraph (a) of this Section 7 and by the Guarantor in the case of parties to be indemnified pursuant to paragraph (b) of this Section 7. An indemnifying party

shall not be liable for any settlement of any proceeding effected without its prior written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party (which consent shall not be unreasonably withheld or delayed), effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding 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 the indemnified party.

(d) To the extent the indemnification provided for in Section 7(a) or 7(b) hereof is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Trust and the Guarantor, on the one hand, and each Underwriter, on the other hand, from the offering of such Normal PPS or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Trust and the Guarantor, on the one hand, and each Underwriter, on the other hand, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Trust and the Guarantor, on the one hand, and each Underwriter, on the other hand, in connection with the offering of such Normal PPS shall be deemed to be in the same respective proportions as the total net proceeds from the offering of such Normal PPS (before deducting expenses) received by the Trust bear to the total discounts and commissions received by each Underwriter in respect thereof. The relative fault of the Trust and the Guarantor, on the one hand, and each Underwriter, on the other hand, 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 Trust and the Guarantor or by such Underwriter and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. Each Underwriter’s obligation to contribute pursuant to this Section 7 shall be several in the proportion that the number of Normal PPS the sale of which by such Underwriter gave rise to such losses, claims, damages or liabilities bears to the aggregate number of Normal PPS the sale of which by all Underwriters gave rise to such losses, claims, damages or liabilities, and not joint.

(e) The Trust and the Guarantor and the Underwriters agree that it would not be just or equitable if contribution pursuant to Section 7(d) hereof 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 that does not take account of the equitable considerations referred to in Section 7(d) hereof. The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 7(d) hereof shall be deemed to include, subject to the limitations set forth above, 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 Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Normal PPS referred to in Section 7(d) hereof that were offered and sold to the public through such Underwriter exceeds the amount of any damages that 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.

8. Default by an Underwriter. If any one or more Underwriters shall fail to purchase and pay for any of the Normal PPS agreed to be purchased by such Underwriter or Underwriters hereunder, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the number of Normal PPS set forth opposite their names in Schedule II hereto bear to the aggregate number of Normal PPS set forth opposite the names of all the remaining Underwriters) the Normal PPS which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate number of Normal PPS which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate number of Normal PPS set forth in Schedule II hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of such Normal PPS; provided further, that if the remaining Underwriters do not exercise their right to purchase such Normal PPS and arrangements for the purchase of such Normal PPS satisfactory to the Trust and the Guarantor and the Representative are not made within 36 hours after such default, then this Agreement will terminate without liability to any nondefaulting Underwriter, the Trust and the Guarantor. In the event of a default by any Underwriter as set forth in this Section 8, the Closing Date shall be postponed for such period, not exceeding seven days, as the Representative shall determine in order that the required changes in the Registration Statement and the Final Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Trust or the Guarantor and any nondefaulting Underwriter for damages occasioned by its default hereunder.

9. Underwriter Representations and Agreements.
