Ladies and Gentlemen:

WPS Resources Corporation, a Wisconsin corporation (the "Company") confirms its agreement (the "Agreement") with the underwriters named in Schedule A (collectively, the "Underwriters," which term shall also include any underwriter substituted as hereinafter provided in Section 10 hereof), for whom you are acting as representatives (the "Representatives"), with respect to (a) the issue and sale by the Company and the purchase by the Underwriters, acting severally and not jointly, of the number of shares of common stock, par value $1.00 per share, of the Company (the "Common Stock"), including the related common stock purchase rights (the "Rights") provided for in the Rights Agreement dated December 12, 1996, between the Company and Firstar Trust Company, as rights agent (the "Rights Agreement") (all references herein to the Common Stock shall include the Rights unless the context indicates otherwise) indicated in Schedule A hereto at the public offering price and on the other terms and conditions set forth on Schedule B, and (b) the grant by the Company to the Underwriters, acting severally and not jointly, of an option to purchase all or any part of up to 300,000 additional shares, in the aggregate, to cover over-allotments, as more fully set forth in Section 2(b). The 2,000,000 shares of Common Stock referred to in Schedule A are collectively referred to herein as the "Firm Shares," the 300,000 additional shares to be issued and sold to the Underwriters upon exercise of the option described in the preceding sentence are collectively referred to herein as the "Option Shares," and the Firm Shares and the Option Shares are collectively referred to herein as the "Shares." If the firm or firms listed in Schedule A hereto include only the firm or firms described above as Representatives, then the terms "Underwriters" and "Representatives", as used herein, shall each be deemed to refer to such firm or firms. The Shares are more fully described in the Final Prospectus (as defined below).

The Company has filed with the Securities and Exchange Commission (the "Commission") a registration statement on Form S-3 (No. 333-88525) relating to the Shares and the offering thereof from time to time in accordance with Rule 415 under the Securities Act of 1933, as amended (the "1933 Act"), and has filed such amendments thereto as may have been required to the date hereof. Such registration statement, as amended, has been declared effective by the Commission. The Company has filed with the Commission pursuant to Rule 424(b) under the 1933 Act any preliminary prospectus used in connection with the offering of the Shares prior to the date hereof and required to be so filed. The Company proposes to file with the Commission pursuant to Rule 424(b) under the 1933 Act a supplement to the form of prospectus included in such registration statement relating to the Shares and the plan of distribution thereof. Such registration statement, including the exhibits thereto, as amended at the date of this Agreement, is hereinafter called the "Registration Statement;" such prospectus in the form in which it appears in the Registration Statement is hereinafter called the "Base 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 Base Prospectus as so supplemented) is hereinafter called the "Final Prospectus." Any preliminary form of the Final Prospectus which has heretofore been filed pursuant to Rule 424(b) is hereinafter called the "Preliminary Prospectus." Any reference herein to the Registration Statement, the Base Prospectus, any Preliminary 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, as amended (the "1934 Act"), on or before the date of this Agreement, or the issue date of the Base Prospectus, any Preliminary Prospectus or the Final Prospectus, as the case may be; provided that if the Company files a registration statement with the Commission pursuant to Rule 462(b) under the Act (the "Rule 462(b) Registration Statement"), then, after such filing, all references to the "Registration Statement" shall also be deemed to include the Rule 462 Registration Statement; and any reference herein to the terms "amend", "amendment" or "supplement" with respect to the Registration Statement, the Base Prospectus, any Preliminary Prospectus or the Final Prospectus shall be deemed to refer to and include the filing of any document under the 1934 Act after the date of this Agreement, or the issue date of the Base Prospectus, any Preliminary Prospectus or the Final Prospectus, as the case may be, deemed to be incorporated therein by reference. All references in this Agreement to financial statements and schedules and other information which is "contained," "included" or "stated" in the Registration Statement or the Final Prospectus (and all other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information that are or are deemed to be incorporated by reference in the Registration Statement or the Final Prospectus, as the case may be.

For purposes of this Agreement, all references to the Registration Statement, the Base Prospectus, any Preliminary Prospectus, the Final Prospectus or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System ("▇▇▇▇▇").

     (xvi) Public Utility Holding Company Act Compliance. The Company is not currently required to register as a "holding company" under the Public Utilities Holding Company Act of 1935, as amended.

    (xviii) Exhibits. There are no contracts or other documents of the Company or any of its subsidiaries which are required to be described in the Registration Statement, any Preliminary Prospectus, the Final Prospectus, or the documents incorporated by reference therein or to be filed as exhibits thereto which have not been so described and filed as required.

    (xix) Licenses and Authorizations.

Except as set forth in the Registration Statement and Final Prospectus, neither the Company nor any of its subsidiaries has been named as a "potentially responsible party" under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended, except in such instances which would not, individually or in the aggregate, have a Material Adverse Effect.

    (xxiii) Investment Company Act. The Company is not an "investment company or a company "controlled" by an "investment company" within the meaning of the Investment Company Act of 1940, as amended (the "Investment Company Act"), and is not required to register or take any other action with respect to or under the Investment Company Act by reason of the issuance of the Shares by the Company.

    (xxiv) Listing of the Securities. The Shares have been approved for listing on the New York Stock Exchange.

(b) Officer Certificates. Any certificate signed by any officer of the Company or any of its subsidiaries that is delivered to the Underwriters shall be deemed a representation and warranty by the Company to each Underwriter as to the matters stated therein.

SECTION 2. SALE AND DELIVERY TO UNDERWRITERS; CLOSING.

Purchase and Sale. (a) Firm Shares. Subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, the Company agrees to issue and sell to each Underwriter, and each Underwriter, severally and not jointly, agrees to purchase from the Company, at the public offering price and upon the terms and conditions set forth in Schedule B hereto the number of Firm Shares set forth opposite such Underwriter's name in Schedule A hereto.

(b) Option Shares. In addition, subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, the Company hereby grants an option to the Underwriters, severally and not jointly, to purchase, in the aggregate, up to an additional 300,000 shares of Common Stock at the public offering price per share set forth in Schedule B, less an amount per share equal to any dividends or distributions declared by the Company and payable on the Firm Shares but not payable on the Option Shares. The option hereby granted will expire 30 days after the date hereof and may be exercised in whole or in part from time to time only for the purpose of covering over-allotments which may be made in connection with the offering and distribution of the Firm Shares upon notice by the Representatives to the Company setting forth the number of Option Shares as to which the several Underwriters are then exercising the option and the time and date of payment and delivery of such Option Shares. Any such time and date of delivery (a "Date of Delivery") shall be determined by the Representatives, but shall not be later than seven full business days after the exercise of the option nor in any event prior to the Closing Time (as defined in Section 2(d)). If the option is exercised as to all or any portion of the Option Shares, each of the Underwriters, acting severally and not jointly, shall purchase that proportion of the total number of Option Shares then being purchased which the number of Firm Shares set forth opposite such Underwriter's name in Schedule A bears to the total number of Firm Shares, subject in each case to such adjustments as the Representatives in their discretion shall make to eliminate fractional shares.

(c) Underwriting Commission. As compensation for their commitments hereunder, the Company will pay to the Representatives, for the account of the Underwriters, at the Closing Time or on each Date of Delivery, if any, an amount equal to the total underwriting commission specified in Schedule B for the Firm Shares or the Option Shares sold and delivered by the Company at the Closing Time or such Date of Delivery, as applicable.

(d) Delivery and Payment. Delivery of the Shares shall be made at the office of The Depository Trust Company ("DTC"). The closing of the sale of the Firm Shares shall take place at the offices of ▇▇▇▇▇ & ▇▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇ or at such other place as shall be agreed upon by the Company and the Underwriters, at 9:00 A.M. (central time) on the third (fourth, if the pricing occurs after 4:30 P.M. (Eastern time) on any given day) business day after the date hereof (unless postponed in accordance with the provisions of Section 10), or such other time not later than ten business days after such date as shall be agreed upon by the Underwriters and the Company (such time and date being herein called the "Closing Time"). In the event that any or all of the Option Securities are purchased by the Underwriters, the closing of the sale of the Option Shares shall take place at the above-mentioned offices or at such other place as shall be agreed upon by the Company and the Representatives on each Date of Delivery specified in the notice from the Underwriters to the Company.

At the Closing Time and on each Date of Delivery, the Company will deliver the Firm Shares or the Option Shares, as applicable, to the Representatives, for the account of each Underwriter, against payment by and on behalf of such Underwriter, of a purchase price equal to the purchase price specified in Section 2(a) or 2(b), as applicable. If the Firm Shares or the Option Shares are to be issued in book-entry form, such delivery shall be made by causing DTC to credit the Firm Shares or the Option Shares, as applicable, to the account of the Representatives at DTC. Payment of the purchase price shall be made to the Company by wire transfer of immediately available funds to a bank account designated by the Company. It is understood that each Underwriter has authorized the Representatives, for its account, to accept delivery of, issue receipt for, and make payment of the purchase price for, the Firm Shares and the Option Shares which it has agreed to purchase.

At the Closing Time or on each Date of Delivery, the Company will pay, or cause to be paid, the total underwriting commission payable to the Underwriters at such time under Section 2(c) with respect to the Firm Shares or the Option Shares, as applicable, to a bank account designated by the Representatives, on behalf of the Underwriters, by wire transfer of immediately available funds. If mutually agreed by the Company and the Underwriters, the amount of the total underwriting commission due to the Underwriters may be offset by the Underwriters against the amount of the purchase price for the Firm Shares or the Option Shares, as applicable, payable by the Underwriters to the Company pursuant to Section 2(a) or 2(b), as applicable.

SECTION 3. COVENANTS OF THE COMPANY. The Company covenants with each Underwriter as follows:

(a) Compliance with Securities Regulations and Commission Requests. Immediately following the execution of this Agreement, the Company will prepare a Final Prospectus setting forth the number of Shares covered thereby, the names of the Underwriters and the number of Shares which each severally has agreed to purchase, the names of the Representatives, the price at which the Shares are to be purchased by the Underwriters from the Company, the initial public offering price, the selling concession and reallowance, if any, and such other information as the Representatives and the Company deem appropriate in connection with the offering of the Shares. The Company will promptly transmit copies of the Final Prospectus to the Commission for filing pursuant to Rule 424 of the 1933 Act and will furnish to the Underwriters named therein as many copies of the Final Prospectus and any Preliminary Prospectus as such Underwriters shall reasonably request.

(b) Amendments. The Company will notify the Representatives immediately, and promptly confirm the notice in writing, (i) when any post-effective amendment to the Registration Statement shall become effective, or (ii) of the mailing or the delivery to the Commission for filing, after the date of this Agreement and prior to the Closing Time, of any supplement to the Final Prospectus or any document to be filed pursuant to the 1934 Act which will be incorporated by reference into the Registration Statement or Final Prospectus, (iii) of the receipt of any comments or other communications from the Commission with respect to the Registration Statement, the Base Prospectus, any Preliminary Prospectus or the Final Prospectus, (iv) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Base Prospectus, any Preliminary Prospectus or the Final Prospectus or for additional information, and (v) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement, of any order preventing or suspending the use of any Preliminary Prospectus, or of the suspension of the qualification of the Shares for offering or sale in any jurisdiction, or of the initiation or threatening of any proceedings for any of such purposes. The Company will promptly effect the filings necessary pursuant to Rule 424 (b) and will take such steps as it deems necessary to ascertain promptly whether the form of prospectus transmitted for filing under Rule 424(b) was received for filing by the Commission and, in the event that it was not, it will promptly file such prospectus. The Company will make every reasonable effort to prevent the issuance of any stop order and, if any stop order is issued, to obtain the lifting thereof at the earliest possible moment.

The Company will give the Underwriters notice of its intention to file or prepare any amendment to the Registration Statement or any amendment, supplement or revision to either the prospectus included in the Registration Statement at the time it became effective or to the Final Prospectus, whether pursuant to the 1933 Act, the 1934 Act or otherwise, will furnish the Underwriters with copies of any such documents a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file or use any such document (excluding documents incorporated by reference in the Registration Statement) to which the Underwriters or counsel for the Underwriters shall reasonably object.

(c) Delivery of Registration Statements. The Company has furnished or will deliver to the Underwriters and counsel for the Underwriters, without charge, such number of signed and conformed copies of the Registration Statement as originally filed and of each amendment thereto (including exhibits filed therewith or incorporated by reference therein and documents incorporated or deemed to be incorporated by reference therein) and signed copies of all consents and certificates of experts. The copies of the Registration Statement and each amendment thereto furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to ▇▇▇▇▇, except to the extent permitted by Regulation S-T.

(d) Delivery of Prospectuses. The Company will furnish to each Underwriter, without charge, during the period when the Final Prospectus is required to be delivered under the 1933 Act or the 1934 Act, such number of copies of the Final Prospectus (as amended or supplemented following the date of this Agreement) as such Underwriter may reasonably request.

(e) Continued Compliance with Securities Laws. The Company will comply with the 1933 Act and the 1933 Act Regulations and the 1934 Act and the 1934 Act Regulations so as to permit the completion of the distribution of the Securities as contemplated in this Agreement and in the Final Prospectus. If at any time when a prospectus is required by the 1933 Act to be delivered in connection with sales of the Shares, any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Underwriters or for the Company, to amend the Registration Statement or amend or supplement the Final Prospectus in order that the Final Prospectus will not include any untrue statements of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a purchaser, or if it shall be necessary, in the opinion of such counsel, at any such time to amend the Registration Statement or amend or supplement the Final Prospectus in order to comply with the requirements of the 1933 Act or the 1933 Act Regulations, the Company will promptly prepare and file with the Commission, subject to Section 3(b), such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement or the Final Prospectus comply with such requirements, and the Company will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request.

(f) Rule 158. The Company will timely file such reports pursuant to the 1934 Act as are necessary in order to make generally available to its securityholders as soon as practicable an earnings statement for the purposes of, and to provide the benefits contemplated by, the last paragraph of Section 11(a) of the 1933 Act.

(g) Use of Proceeds. The Company will use the proceeds received by it from the sale of the Shares in the manner specified in the Final Prospectus under "Use of Proceeds."

(h) Restriction on Sale of Common Stock. For the period beginning on the date of this Agreement and ending on the date specified in Schedule B, the Company will not, without the Representatives' prior written consent, directly or indirectly, sell, offer to sell, grant any option for the sale of, enter into an agreement to sell, or otherwise dispose of, any shares of Common Stock or any securities convertible into or exercisable for shares of Common Stock, except for shares of Common Stock sold pursuant to this Agreement and shares of Common Stock offered and sold under the Company's Stock Investment Plan or employee or director benefit or compensation plans of the Company or its wholly-owned subsidiaries described in, or filed or incorporated by reference as an exhibit to, the documents incorporated or deemed incorporated by reference in the Registration Statement and Final Prospectus and the Company will not file a registration statement under the 1933 Act with respect to any such securities or any such securities of the Company held by others.

(j) Listing of Shares. The Company will file all documents and notices and take such further actions as may be required to list the Shares on the New York Stock Exchange.

The Company will pay all expenses incident to the performance of the Company's obligations under this Agreement, including, but not limited to, (i) the preparation, reproduction and filing of the Registration Statement (including financial statements and exhibits) as originally filed and of each amendment thereto, (ii) the preparation, issuance and delivery of the certificates for the Shares to the Underwriters, including any transfer taxes and any stamp or other duties payable upon the sale, issuance, or delivery of the Securities, (iii) all fees and expenses in connection with the listing of the Shares on the New York Stock Exchange, (iv) the printing and delivery to the Underwriters of copies of each Preliminary Prospectus, the Final Prospectus, and any amendments or supplements thereto, (v) the fees and expenses of any transfer agent or registrar for the Shares, and (vi) the cost, if any, of qualifying the Shares with The Depository Trust Company.

(b) Termination of Agreement. If this Agreement is terminated by the Underwriters in accordance with the provisions of Section 5 or Section 10(b) hereof, the Company shall reimburse the Underwriters for all of their reasonable out-of-pocket expenses, including the fees and disbursements of counsel for the Underwriters.

SECTION 5. CONDITIONS OF UNDERWRITERS' OBLIGATIONS. (a) The obligations of the several Underwriters hereunder to purchase the Firm Share are subject to the accuracy of the representations and warranties of the Company contained in Section 1 hereof or in certificates of any officer of the Company or any subsidiary delivered pursuant to the provisions hereof, to the performance by the Company of its covenants and other obligations hereunder, and to the following further conditions:

    (i) Effectiveness of Registration Statement. The Final Prospectus shall have been filed with the Commission pursuant to Rule 424(b) within the applicable time period prescribed for such filing by the 1933 Act Regulations, and no stop order suspending the effectiveness of the Registration Statement or any part thereof shall have been issued and no proceeding for that purpose shall have been initiated or threatened by the Commission.

    (ii) Opinion of Counsel for the Company. At Closing Time, the Underwriters shall have received the favorable opinion, dated as of Closing Time, of ▇▇▇▇▇ & ▇▇▇▇▇▇▇, counsel for the Company, in form and substance satisfactory to counsel for the Underwriters, to the effect set forth in Exhibit A hereto.

    (iii) Opinion of Counsel for Underwriters. At Closing Time, the Underwriters shall have received the favorable opinion, dated as of Closing Time, of ▇▇▇▇▇▇ ▇▇▇▇▇▇ & ▇▇▇▇▇, counsel for the Underwriters, with respect to the validity of the Shares, the Registration Statement, the Final Prospectus and other related matters as the Underwriters may reasonably request (it being understood that such counsel may rely as to all matters of Wisconsin law and legal conclusions based thereon upon the opinion of counsel for the Company referred to in Section 5(b)). Such counsel may also state that, insofar as such opinion involves factual matters, they have relied, to the extent they deem proper, upon certificates of officers of the Company and its subsidiaries and certificates of public officials.

    (iv) Officer Certificates. At Closing Time, there shall not have been, since the date hereof or since the respective dates as of which information is given in the Final Prospectus, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries, considered as one enterprise, whether or not arising in the ordinary course of business, and the Underwriters shall have received certificates of the President or a Vice President of the Company and of the chief financial or chief accounting officer of the Company, dated as of Closing Time, to the effect that (A) there has been no such material adverse change, (B) the representations and warranties in Section 1(a) hereof are true and correct with the same force and effect as though expressly made at and as of Closing Time, (C) the Company has complied with all agreements and satisfied all conditions on its part to be performed or satisfied at or prior to Closing Time, and (D) 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, to the best knowledge of the Company, are threatened by the Commission.

    (v) Accountant's Comfort Letter. At the time of the execution of this Agreement, the Underwriters shall have received from ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ LLP a letter, dated as of the date hereof, in form and substance reasonably satisfactory to the Underwriters, to the effect that:

    (A) they are independent public accountants with respect to the Company and its subsidiaries within the meaning of the 1933 Act and the applicable 1933 Act Regulations;

    (B) in their opinion, the audited consolidated financial statements and financial statement schedule(s) incorporated by reference in the Registration Statement and the Final Prospectus and included in the Company's most recent Annual Report on Form 10-K (the "Form 10-K") comply as to form in all material respects with the applicable accounting requirements of the 1933 Act, the 1933 Act Regulations, the ▇▇▇▇ ▇▇▇ and the applicable 1934 Act Regulations;

    (C) on the basis of (I) the performance of procedures specified by the American Institute of Public Accountants for a review of interim financial information as described in Statement on Auditing Standards No. 71, Interim Financial Information, on the unaudited consolidated balance sheets, the unaudited consolidated statements of income and retained earnings, and the unaudited consolidated statements of cash flows, of the Company and its subsidiaries included in the Company and WPSC's quarterly reports on Form 10-Q filed with the Commission under Section 13 of the 1934 Act (the "Form 10-Q's") subsequent to the Form 10-K, (II) a reading of the latest available unaudited financial statements of the Company and its subsidiaries, (III) a reading of the minutes of the Annual Meeting of Shareholders and the latest minutes of meetings of the Board of Directors of the Company as set forth in the minute books for the current year, and (IV) inquiries of the officers of the Company who have responsibility for financial and accounting matters (it being understood that the foregoing procedures do not constitute an audit made in accordance with generally accepted accounting procedures and would not necessarily reveal matters of significance with respect to the comments made in such letter, and accordingly that ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ LLP makes no representation as to the sufficiency of such procedures for the purposes of the several Underwriters), nothing has come to their attention which caused them to believe that (1) any material modifications should be made to the unaudited consolidated financial statements included in the Form 10-Q's for them to be in conformity with generally accepted accounting procedures; (2) the unaudited consolidated financial statements included in the Form 10-Q's do not comply as to form in all material respects with the applicable accounting requirements of the 1934 Act and the 1934 Act Regulations, as they apply to Form 10-Q, or (3) at the date of the latest available consolidated financial statements and at a specified date not more than three business days prior to the date of such letter, there was any change in the consolidated capital stock or increase in the consolidated long-term debt of the Company and its subsidiaries or any decrease in the consolidated net assets or shareholders' equity of the Company, in each case as compared with the amounts shown in the most recent consolidated balance sheet of the Company incorporated by reference into the Registration Statement and the Final Prospectus or, during the period from the date of such balance sheet to a specified date not more than three business days prior to the date of such letter, based upon inquiries of the appropriate officers of the Company, there were any decreases, as compared with the corresponding period in the preceding year, in consolidated operating revenues, consolidated net income or net income per share, except in each case as set forth in or contemplated by the Registration Statement and the Final Prospectus or except for such exceptions enumerated in such letter as shall have been agreed to by the Underwriters and the Company; and

    (D) in addition to the audits referred to in their report appearing in the Form 10-K incorporated by reference in the Registration Statement and the Final Prospectus and the limited procedures referred to in clause (C) above, they have carried out certain other specified procedures, not constituting an audit, with respect to certain amounts, percentages, and financial information which are included or incorporated by reference in the Registration Statement and the Final Prospectus and which are specified by the Underwriters, and have found such amounts, percentages, and financial information to be in agreement with the relevant accounting, financial and other records of the Company and its subsidiaries identified in such letter.

    (vi) Bring-down Comfort Letter. At Closing Time, the Underwriters shall have received from ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ LLP a letter, dated as of Closing Time, to the effect that they reaffirm the statements made in the letter furnished pursuant to subsection (v) of this Section, except that the specified date referred to shall be a date not more than three calendar days prior to Closing Time.

     (vii) Approval of Listing. The Shares shall have been duly listed, subject to official notice of issuance, on The New York Stock Exchange.

(b) In the event that the Underwriters exercise their option to acquire the Option Shares, their several obligations to purchase the Option Shares are subject to the accuracy of the representations and warranties of the Company contained in Section 1 hereof or in certificates of any officer of the Company or any subsidiary delivered pursuant to the provisions hereof, in each case on and as of the Date of Delivery, and to the satisfaction as of the Date of Delivery of each of the conditions set forth in Section 5(a) (i) through (vii), except that (i) the opinions called for in Section 5(a)(ii) and (iii) shall be revised to reflect the sale of the Option Shares and shall be dated the Date of Delivery, if different from the Closing Time, and (ii) the bring-down comfort letter called for in Section 5(a)(vi) shall be dated the Date of Delivery, if different from the Closing Time, and the specified date referred to shall be a date not more than three calendar days prior to the Date of Delivery, if different from the Closing Time.

(c) Additional Documents. At Closing Time and on each Date of Delivery, if any, counsel for the Underwriters shall have been furnished with such documents and opinions as they may require for the purpose of enabling them to pass upon the issuance and sale of the Shares as herein contemplated, or in order to evidence the accuracy of any of the representations or warranties, or the fulfillment of any of the conditions, herein contained; and all proceedings taken by the Company in connection with the issuance and sale of the Shares as herein contemplated shall be satisfactory in form and substance to the Underwriters and their counsel.

If any condition specified in this Section shall not have been fulfilled when and as required to be fulfilled, this Agreement may be terminated by the Representatives, on behalf of the Underwriters, by notice to the Company at any time at or prior to Closing Time, or, in the case of any condition to the purchase of Option Shares, at any time at or prior to a Date of Delivery which is after the Closing Date, and such termination shall be without liability of any party to any other party, except as provided in Section 4 and except that Sections 1, 6, 7 and 8 shall survive any such termination and remain in full force and effect.

SECTION 6. INDEMNIFICATION

(a) Indemnification of Underwriters. The Company agrees to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

    (i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto) or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included in any Preliminary Prospectus or the Final Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

    (ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that any such settlement is effected with the written consent of the Company; and

    (iii) against any and all expense whatsoever (including the fees and disbursements of counsel chosen by the Representatives) reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, at the time that such expense is incurred, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment or supplement thereto) or the Base Prospectus, any Preliminary Prospectus or the Final Prospectus (or any amendment or supplement thereto); and provided further, that the foregoing indemnity with respect to any untrue statement or omission from a Preliminary Prospectus shall not inure to the benefit of any Underwriter (or any person controlling such Underwriter) from whom the person asserting such loss, liability, claim, damage or expense purchased any of the Shares that are the subject thereof if the Company shall sustain the burden of proving that: (i) the untrue statement or omission contained in the Preliminary Prospectus (excluding documents incorporated by reference) was corrected, (ii) such person was not sent or given a copy of the Final Prospectus (excluding documents incorporated by reference) which corrected the untrue statement or omission at or prior to the written confirmation of the sale of such Shares to such person if required by applicable law, and (iii) the Company satisfied its obligation to provide a sufficient number of copies of the Final Prospectus to such Underwriter.

(b) Indemnification of Company, Officers and Directors. Each Underwriter severally agrees to indemnify and hold harmless the Company, the Company's directors, each of the Company's officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto) or any Preliminary Prospectus or the Final Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto) or in such Preliminary Prospectus or the Final Prospectus (or any amendment or supplement thereto).

(c) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 6(a) above, counsel to the indemnified parties shall be selected by ▇. ▇. ▇▇▇▇▇▇▇ & Sons, Inc., in consultation with the other Representatives, and, in the case of parties indemnified pursuant to Section 6(b) above, counsel to the indemnified parties shall be selected by the Company, in each case reasonably acceptable to the indemnifying party. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own 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. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim, and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

SECTION 7. CONTRIBUTION. If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Shares pursuant to this Agreement or (ii) if the allocation provided by clause (i) 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 Company on the one hand and of the Underwriters on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the offering of the Shares pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Shares pursuant to this Agreement (before deducting expenses) received by the Company and the total underwriting commission received by the Underwriters, in each case as set forth on the cover of the Final Prospectus, bear to the aggregate initial public offering price of the Shares as set forth on such cover.

The relative fault of the Company on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 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 Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares 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 ▇▇▇▇ ▇▇▇) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company, within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The Underwriters' respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of Shares set forth opposite their respective names in Schedule A hereto and not joint.

SECTION 8. REPRESENTATIONS AND WARRANTIES TO SURVIVE DELIVERY. All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of its subsidiaries submitted pursuant hereto shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or controlling person, or by or on behalf of the Company, and shall survive delivery of the Shares to the Underwriters.

SECTION 9. TERMINATION OF AGREEMENT

(a) Termination; General. The Representatives may terminate this Agreement, by notice to the Company, at any time at or prior to the Closing Time (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Final Prospectus, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries, considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable to market the Shares or to enforce contracts for the sale of the Shares, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the New York Stock Exchange, or if trading generally on the New York Stock Exchange has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, the National Association of Securities Dealers, Inc. or any governmental authority, or if a banking moratorium has been declared by either Federal, New York or Wisconsin authorities.

(b) Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7 and 8 shall survive such termination and remain in full force and effect.

SECTION 10. DEFAULT BY ONE OR MORE UNDERWRITERS. If one or more of the Underwriters shall fail at Closing Time to purchase the Shares (other than for some reason to justify, in accordance with the provisions hereof, the cancellation or termination of its or their obligations hereunder) which it or they are obligated to purchase under this Agreement (the "Defaulted Shares"), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Shares in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:

(a) if the number of Defaulted Shares does not exceed 10% of the number of Shares to be purchased on such date, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(b) if the number of Defaulted Shares exceeds 10% of the number of Shares to be purchased on such date, this Agreement or, with respect to any Date of Delivery which occurs after Closing Time, the obligation of the Underwriters to purchase and of the Company to sell the Option Shares to be purchased and sold on such Date of Delivery, shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement, or, in the case of a Date of Delivery which is after Closing Time, which does not result in a termination of the obligation of the Underwriters to purchase and the Company to sell the relevant Option Shares, as the case may be, either the Representatives or the Company shall have the right to postpone the Closing Time or the relevant Date of Delivery for a period not exceeding seven days in order to effect any required changes in the Registration Statement or Final Prospectus or in any other documents or arrangements.

SECTION 11. NOTICES. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the Underwriters shall be directed to ▇. ▇. ▇▇▇▇▇▇▇ & Sons, Inc. at ▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇. ▇▇▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇▇, attention Equity Syndicate Manager, (fax no.: ▇▇▇-▇▇▇-▇▇▇▇) and notices to the Company shall be directed to it at ▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇, P.

SECTION 12. PARTIES. This Agreement shall inure to the benefit of and be binding upon the Underwriters and the Company, and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters and the Company, and their respective successors and the controlling persons, officers and directors referred to in Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriters and the Company and their respective successors, and said controlling persons, officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Shares from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

SECTION 13. GOVERNING LAW AND TIME. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. SPECIFIED TIMES OF DAY REFER TO CENTRAL TIME.

SECTION 14. EFFECT OF HEADINGS. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

SECTION 15. SEVERABILITY OF PROVISIONS. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof or affecting the validity or enforceability of such provision in any other jurisdiction.

EXHIBIT A

Form of Opinion of Company's Counsel
(To Be Delivered pursuant to Section 5(a)(ii))

(i) The Company has been duly incorporated and is validly existing as a corporation under the laws of the State of Wisconsin; based solely on a certificate of the Department of Financial Institutions of the State of Wisconsin, the Company has filed its most recent required annual report and, as of the applicable date specified in such certificates, (a) the Company has not filed articles of dissolution with the Department of Financial Institutions of the State of Wisconsin, and (b) the Department of Financial Institutions of the State of Wisconsin has not commenced proceedings for the dissolution of the Company and has made no determination that grounds exist for such action against the Company.
