(c) In addition, on the basis of the representations, warranties and agreements herein contained, and subject to the terms and conditions herein set forth, the Selling Shareholders specified as sellers of Option Shares on Schedule I annexed hereto hereby agree to sell to the Underwriters, and the Underwriters, severally and not jointly, shall have the right at any time within 30 days after the date of the Prospectus to purchase up to the number of Option Shares from such Selling Shareholders at the purchase price per share to be paid for the Firm Shares, for use solely in covering any over-allotments made by the Underwriters in the sale and distribution of the Firm Shares. The option granted hereunder may be exercised upon notice by the Representative to the Attorneys-in-Fact, or either of them, within 30 days after the date of the Prospectus setting forth the aggregate number of Option Shares to be purchased by the Underwriters and sold by such Selling Shareholders, the names and denominations in which the certificates for such shares are to be registered and the date and place at which such certificates will be delivered. Such date of delivery ("Option Closing Date") shall be determined by the Representative, provided that the Option Closing Date, which may be the same as the Firm Closing Date, shall not be earlier than the Firm Closing Date and, if after 24 25 the Firm Closing Date, shall not be earlier than three nor later than ten full business days after delivery of such notice to exercise. Certificates for the Option Shares will be made available for checking and packaging at 9 a.m., Milwaukee, Wisconsin time, on the first full business day preceding the Option Closing Date at a location to be designated by the Representative. The manner of payment for and delivery of (including the denominations of and the names in which certificates are to be registered) the Option Shares shall be the same as for the Firm Shares. (d) The Representative has advised the Attorneys-in-Fact that each Underwriter has authorized the Representative to accept delivery of the Shares and to make payment therefor. It is understood that the Representative, individually and not as representatives of the Underwriters, may (but shall not be obligated to) make payment for any Shares to be purchased by any Underwriter whose funds shall not have been received by the Representative by the Firm Closing Date or the Option Closing Date, as the case may be, for the account of such Underwriter, but any such payment shall not relieve such Underwriter from any obligation under this Agreement. As referred to in this Agreement, "Closing Date" shall mean either the Firm Closing Date or the Option Closing Date. 4. Representation of Underwriters. The Representative will act as the representative for the several Underwriters in connection with the public offering of the Shares, and any action under or in respect of this Agreement taken by the Representative will be binding upon all of the Underwriters. 25 26 5. Information Furnished by the Underwriters. The information set forth in the last paragraph on the outside front cover page of the Prospectus concerning the terms of the offering by the Underwriters, the paragraphs on the inside front cover page of the Prospectus relating to stabilization practices and passive market making, and the concession and reallowance amounts appearing under the caption "Underwriting" in the Prospectus constitute all of the information furnished to the Company by and on behalf of the Underwriters for use in connection with the preparation of the Registration Statement and the Prospectus, as such information is referred to in this Agreement. 6. Covenants of the Company. The Company covenants and agrees with the several Underwriters that: (a) If the effective time of the Registration Statement is not prior to the execution and delivery of this Agreement, then the Company will use its best efforts to cause the Registration Statement to become effective at the earliest possible time and, upon notification from the Commission that the Registration Statement has become effective, will so advise the Representative and counsel to the Underwriters promptly. If the effective time of the Registration Statement is prior to the execution and delivery of this Agreement and any information shall have been omitted therefrom in reliance upon Rule 430A, the Company, at the earliest possible time, will furnish the Representative with a copy of the Prospectus to be filed by the Company with the Commission to comply with Rule 424(b) and Rule 430A under the Act and, if the Representative does not object to the contents thereof, will comply with such Rules. Upon compliance with such Rules, the Company will so advise the Representative promptly. The 26 27 Company will advise the Representative and counsel to the Underwriters and the Attorneys-in-Fact promptly of the issuance by the Commission or any state securities commission of any stop order suspending the effectiveness of the Registration Statement or of the institution of any proceedings for that purpose, or of any notification of the suspension of qualification of the Shares for sale in any jurisdiction or the initiation or threatening of any proceedings for that purpose, and will also advise the Representative and counsel to the Underwriters and the Attorneys-in-Fact promptly of any request of the Commission for amendment or supplement of the Registration Statement, of any Preliminary Prospectus or of the Prospectus, or for additional information, and the Company will not file any amendment or supplement to the Registration Statement (either before or after it becomes effective), to any Preliminary Prospectus or to the Prospectus (including a prospectus filed pursuant to Rule 424(b)), or file any document under the Exchange Act before the termination of the public offering of the Shares by the Underwriters if such document would be deemed to be incorporated by reference in the Registration Statement, if the Representative has not been furnished with a copy prior to such filing (with a reasonable opportunity to review such amendment or supplement) or if the Representative objects to such filing. (b) If, at any time when a prospectus relating to the Shares is required by law to be delivered in connection with sales by an Underwriter or dealer, any event occurs as a result of which the Prospectus would include an untrue statement of a material fact, or would omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were 27 28 made, not misleading, or if it is necessary at any time to supplement the Prospectus to comply with the Act or to file under the Exchange Act any document that would be deemed to be incorporated by reference in the Registration Statement to comply with the Act or the Exchange Act, the Company promptly will advise the Representative and counsel to the Underwriters and the Attorneys-in-Fact thereof and will promptly prepare and file with the Commission, at its expense, an amendment to the Registration Statement or file such document that will correct such statement or omission or an amendment that will effect such compliance; and, if any Underwriter is required to deliver a prospectus after the effective date of the Registration Statement, the Company, upon request of the Representative, will prepare promptly such prospectus or prospectuses as may be necessary to permit compliance with the requirements of Section 10(a)(3) of the Act. The Company consents to the use, in accordance with the provisions of the Act and with the Blue Sky Laws of the jurisdictions in which the Shares are offered by the several Underwriters and by dealers, of each Preliminary Prospectus. (c) Neither the Company nor any Subsidiary will, prior to the Option Closing Date, if any, incur any liability or obligation, direct or contingent, or enter into any material transaction, other than in the ordinary course of business, or enter into any transaction with an "affiliate," as defined in Rule 405 under the Act, that is required to be described in the Prospectus pursuant to Item 404 of Regulation S-K under the Act, except as described in the Prospectus. (d) Neither the Company nor any Subsidiary will, prior to the Option Closing Date, if any, acquire any of the Common Stock 28 29 nor will the Company declare or pay any dividend or make any other distribution upon its Common Stock payable to shareholders of record on a date prior to the Option Closing Date, except as described in the Prospectus. (e) The Company will make generally available to its security holders and the Representative an earnings statement as soon as practicable, but in no event later than 60 days after the end of its fiscal quarter in which the first anniversary of the effective date of the Registration Statement occurs, covering a period of 12 consecutive calendar months beginning after the effective date of the Registration Statement, which will satisfy the provisions of the last paragraph of Section 11(a) of the Act and Rule 158 promulgated thereunder. (f) During such period as a prospectus is required by law to be delivered in connection with sales by an Underwriter or dealer, the Company will furnish to the Representative, at the expense of the Company, copies of the Registration Statement, the Prospectus, any Preliminary Prospectus and all amendments and supplements to any such documents, including any document filed under the Exchange Act and deemed to be incorporated by reference in the Registration Statement, in each case as soon as available and in such quantities as the Representative may reasonably request. (g) The Company will cooperate with the Representative and counsel to the Underwriters in qualifying or registering the Shares for sale under the Blue Sky Laws of such jurisdictions as the Representative designates and will continue such qualifications or 29 30 registrations in effect so long as reasonably requested by the Representative to effect the distribution of the Shares, except that the Company shall not be required to qualify as a foreign corporation or to file a general consent to service of process in any such jurisdiction where it is not presently qualified. In each jurisdiction where any of the Shares shall have been qualified as provided above, the Company will file such reports and statements as may be required to continue such qualification for a period of not less than one year from the date of the Prospectus. The Company shall promptly prepare and file with the Commission, from time to time, such reports as may be required to be filed by the Act and the Exchange Act, and the Company shall comply in all respects with the undertakings given by the Company in connection with the qualification or registration of the Shares for offering and sale under the Blue Sky Laws. (h) During the period of three years from the date of the Prospectus, the Company will furnish to the Representative and to each of the other Underwriters who may so request, as soon as available, each report, statement or other document of the Company or its Board of Directors mailed to its shareholders or filed with the Commission, and such other information concerning the Company as the Representative may reasonably request. (i) The Company shall take all necessary or appropriate action within its power to maintain the authorization for trading of the Common Stock as a New York Stock Exchange security, or take such action to authorize the Common Stock for listing on the New York Stock Exchange or the American Stock Exchange, for a period of at least 36 months after the date of the Prospectus. 30 31 (j) Except for the issuance and sale by the Company of Common Stock upon exercise of presently existing outstanding stock options or pursuant to the 1995 Employee Stock Purchase Plan and the grant of employee stock options pursuant to the Company's 1993 Stock Option Plan (provided that none of such options shall be exercisable for a period of 90 days after the date of the Prospectus), the Company shall not, for a period of 90 days after the date of the Prospectus, without the prior written consent of Cleary Gull, directly or indirectly, offer, sell or otherwise dispose of, contract to sell or otherwise dispose of, or cause or in any way permit to be sold or otherwise disposed of, any: (i) shares of Common Stock; (ii) rights to purchase shares of Common Stock; or (iii) securities that are convertible or exchangeable into shares of Common Stock. (k) The Company will maintain a transfer agent and, if required by law or the rules of the New York Stock Exchange or any national securities exchange on which the Common Stock is listed, a registrar (which, if permitted by applicable laws and rules, may be the same entity as the transfer agent) for its Common Stock. (l) If at any time when a prospectus relating to the Shares is required to be delivered under the Act, any rumor, publication or event relating to or affecting the Company shall occur as a result of which, in the opinion of Cleary Gull, the market price of the Common Stock has been or is likely to be materially affected (regardless of whether such rumor, publication or event necessitates a supplement to the Prospectus), the Company will, after written notice from Cleary Gull advising the Company of any of the matters set forth above, promptly consult with 31 32 Cleary Gull concerning the advisability and substance of, and, if the Company and Cleary Gull determine that it is appropriate, disseminate, a press release or other public statement responding to or commenting on, such rumor, publication or event. (m) The Company will comply or cause to be complied with the conditions to the obligations of the Underwriters in Section 9 hereof. 7. Covenants Of The Selling Shareholders. Each of the Selling Shareholders, severally and not jointly, covenant and agree with the several Underwriters and the Company as follows: (a) If the effective time of the Registration Statement is not prior to the execution and delivery of this Agreement, the Selling Shareholder will cooperate to the extent necessary to cause the Registration Statement to become effective at the earliest possible time; and the Selling Shareholder will do and perform all things to be done and performed by such Selling Shareholder prior to each Closing Date, pursuant to this Agreement or the Power of Attorney and Custody Agreement. (b) The Selling Shareholder agrees to deliver to the Custodian on or prior to the First Closing Date a properly completed and executed United States Treasury Department Form W-9 (or other applicable substitute form or statement specified by Treasury Department regulations in lieu thereof).

(e) The Selling Shareholder will furnish any documents, instruments or other information that the Representative may reasonably request in connection with the sale and transfer of the Shares to the Underwriters. (f) If the sale to the Underwriters of the Firm Shares is not consummated for any reason other than termination of this Agreement pursuant to Section 12 hereof or pursuant to Section 14(b) or 14(d) hereof, without limiting any other rights the Underwriters may have, the Company and/or the Selling Shareholders agree to reimburse the Underwriters upon demand for all out-of-pocket expenses (including reasonable fees and expenses of counsel for the Underwriters) that shall have been incurred by the Underwriters in connection with the proposed purchase and sale of the Shares, and the provisions of Sections 8 and 11 hereof shall at all times be effective and apply. The Selling Shareholders 33 34 agree to cover the first $50,000 of such expenses (together with the expenses provided in section 8 hereof) and the Company shall be responsible for all of such expenses in excess of that amount. (g) If the sale to the Underwriters of the Firm Shares is not consummated for any reason other than termination of this Agreement by the Underwriters pursuant to Section 14 hereof and the Representative has not been reimbursed for its expenses in connection with the transactions contemplated hereby under section 7(f) or otherwise, then the Company and/or the Selling Shareholders, as the case may be, shall offer to hire, on customary terms and conditions, the Representative as financial advisor in connection with the first sale, subsequent to the date hereof, of a material amount of securities of the Company by the Company and/or the Selling Shareholders, as the case may be, in a private or public transaction. The Company and/or the Selling Shareholders can avoid the obligation imposed on each of them under this Section 7(g) as to the Representative by reimbursing the Representative for its expenses relating to the transactions contemplated hereby. 8.

Lee Runzheimer, Chief Financial Officer, of the Company, to the effect that: (i) The representations and warranties of the Company and the Selling Shareholders set forth in Section 2(a) hereof are 45 46 true and correct as of the date of this Agreement and as of the date of such certificate, and the Company has complied with all the agreements and satisfied all the conditions to be performed or satisfied by it at or prior to the date of such certificate; (ii) The Commission has not issued an order preventing or suspending the use of the Prospectus or any Preliminary Prospectus or any amendment or supplement thereto; no stop order suspending the effectiveness of the Registration Statement has been issued; and to the knowledge of the respective signatories, no proceedings for that purpose have been initiated or are pending or contemplated under the Act or under the Blue Sky Laws of any jurisdiction; (iii) Each of the respective signatories has carefully examined the Registration Statement and the Prospectus, and any amendment or supplement thereto, including any documents filed under the Exchange Act and deemed to be incorporated by reference in the Registration Statement, and such documents contain all statements required to be stated therein, and do not include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and since the date on which the Registration Statement was initially filed, no event has occurred that was required to be set forth in an amendment or supplement to the Prospectus or in an amendment to the Registration Statement that has not been so set forth, and there has been no document required to be filed under the Exchange Act that upon such filing would be deemed to be incorporated by reference in the Registration Statement that has not been so filed; and 46 47 (iv) Since the date on which the Registration Statement was initially filed with the Commission, there has not occurred any Material Adverse Change or development involving, or which could be expected to involve, a Material Adverse Change, whether or not arising from transactions in the ordinary course of business, except as disclosed in the Prospectus and the Registration Statement as heretofore amended or (but only if the Representative expressly consent thereto in writing) as disclosed in an amendment or supplement thereto filed with the Commission and delivered to the Representative after the execution of this Agreement; since such date and except as so disclosed or in the ordinary course of business, the Company has not incurred any liability or obligation, direct or indirect, or entered into any transaction which is material to the Company; since such date and except as so disclosed, there has not been any change in the outstanding capital stock of the Company, or any change that is material to the Company in the short-term debt or long-term debt of the Company; since such date and except as so disclosed, the Company has not acquired any of the Common Stock or other capital stock of the Company nor has the Company declared or paid any dividend, or made any other distribution, upon its outstanding Common Stock payable to shareholders of record on a date prior to such Closing Date; since such date and except as so disclosed, the Company has not incurred any material contingent obligations, and no material litigation has commenced or been threatened against the Company; and, since such date and except as so disclosed, the Company has not sustained any material loss or interference from any strike, fire, flood, windstorm, accident or other calamity (whether or not insured) or from any court or governmental action, order or decree. 47 48 The delivery of the certificate provided for in this subsection (g) shall be and constitute a representation and warranty of the Company as to the facts required in the immediately foregoing clauses (i), (ii), (iii) and (iv) to be set forth in said certificate. (h) The Representative shall have received a certificate from each of the Selling Shareholders (which may be signed by such Selling Shareholder's Attorneys-in-Fact, or either of them), dated the Firm Closing Date or the Option Closing Date, as applicable, to the effect that: (i) the representations and warranties of such Selling Shareholder in Sections 2 and 3 of this Agreement are true and correct as of the date of this Agreement and as of the date of such certificate, as if again made on and as of such Closing Date, and the Selling Shareholder has complied with all of the agreements and satisfied all of the conditions to be performed or satisfied by the Selling Shareholder at or prior to such Closing Date; and (ii) the Selling Shareholder has no reason to believe that the Registration Statement or any amendment thereto, including any documents filed under the Exchange Act and deemed to be incorporated by reference in the Registration Statement, at the time it was declared effective by the Commission contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary to make the statements therein not misleading, or that the Prospectus, as amended or supplemented, including any documents filed under the Exchange Act and deemed to be incorporated by reference in the Registration Statement, contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. 48 49 (i) At the time this Agreement is executed and also on each Closing Date, there shall be delivered to the Representative a letter addressed to the Representative, as representatives of the Underwriters, from Deloitte & Touche LLP, the Company's independent accountants, the first letter to be dated the date of this Agreement, the second letter to be dated the Firm Closing Date and the third letter (if applicable) to be dated the Option Closing Date, which shall be in form and substance satisfactory to the Representative and shall, without limitation, contain financial information concerning the Company and the Subsidiaries as of a date within five days of the date of such letter. There shall not have been any change or decrease set forth in any of the letters referred to in this subsection (i) that makes it impracticable or inadvisable in the judgment of the Representative to proceed with the public offering or purchase of the Shares as contemplated hereby. (j) The Shares shall have been qualified or registered for sale under the Blue Sky Laws of such jurisdictions as shall have been specified by the Representative, and the underwriting terms and arrangements for the offering shall have been cleared by the NASD. (k) Such further certificates and documents as the Representative may reasonably request (including certificates of officers of the Company). All such opinions, certificates, letters and documents shall be in compliance with the provisions hereof only if they are satisfactory to the Representative and to Reinhart, Boerner, Van Deuren, Norris & Rieselbach, s.c., counsel for the Underwriters, which 49 50 Representative and Firm agree to act reasonably in so determining. The Company and the Selling Shareholders shall furnish the Representative with such manually signed or conformed copies of such opinions, certificates, letters and documents as the Representative may reasonably request. If any condition to the Underwriters' obligations hereunder to be satisfied prior to or at either Closing Date is not so satisfied, this Agreement at the election of the Representative will terminate upon notification to the Company and the Attorneys-in-Fact, or any one of them, for the Selling Shareholders, without liability on the part of any Underwriter, including the Representative, the Company or the Selling Shareholders except for the provisions of Section 7(f) hereof, the expenses to be paid by the Company and/or the Selling Shareholders pursuant to Section 8 hereof and except to the extent provided in Section 11 hereof. 10. Maintain Effectiveness of Registration Statement. The Company will use its best efforts and the Selling Shareholders will use their best efforts to prevent the issuance of any stop order suspending the effectiveness of the Registration Statement and, if such stop order is issued, to obtain as soon as possible the lifting thereof. 11. Indemnification. (a) The Company and the Selling Shareholders, jointly and severally, agree to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of the Act or the Exchange Act from and against any losses, claims, damages, expenses, liabilities or actions in respect thereof ("Claims"), joint or several, to which such Underwriter or each such 50 51 controlling person may become subject under the Act, the Exchange Act, Blue Sky Laws or other federal or state statutory laws or regulations, at common law or otherwise (including payments made in settlement of any litigation), insofar as such Claims arise out of or are based upon any breach of any representation, warranty or covenant made by the Company and/or the Selling Shareholders in this Agreement, or any untrue statement or Statement, any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto, or in any application filed under any Blue Sky Law or other document executed by the Company for that purpose or based upon written information furnished by the Company and filed in any state or other jurisdiction to qualify any or all of the Shares under the securities laws thereof (any such document, application or information being hereinafter called a "Blue Sky Application") 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. The Company and the Selling Shareholders, jointly and severally, agree to reimburse each Underwriter and each such controlling person for any legal fees or other expenses incurred by such Underwriter or any such controlling person in connection with investigating or defending any such Claim; provided, however, that the Company and the Selling Shareholders will not be liable in any such case to the extent that any such Claim arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, the Prospectus or supplement thereto or in any Blue Sky Application in reliance upon and in conformity with the written information furnished to the Company pursuant to Section 5 of this Agreement and provided, further, that with respect to any 51 52 untrue statement or omission, or alleged untrue statement or omission, made in any Preliminary Prospectus, the indemnity agreement contained in this subsection 11(a) shall not inure to the benefit of any Underwriter from whom the person asserting any such losses, claims, damages or liabilities purchased shares if such untrue statement or omission or alleged untrue statement or omission made in such Preliminary Prospectus is eliminated or remedied in the Prospectus (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto to the Underwriters) and such loss, claim, damage or liability of such Underwriter results from the fact that there was not furnished to such person, at or prior to the written confirmation of the sale of such Shares to such person, a copy of the Prospectus (as so amended or supplemented) if the Company had previously furnished copies thereof to such Underwriter. The indemnification obligations of the Company and the Selling Shareholders as provided above are in addition to and in no way limit any liabilities the Company and the Selling Shareholders may otherwise have. (b) Each Underwriter, severally and not jointly, will indemnify and hold harmless the Company, each of its directors and each of its officers who signs the Registration Statement, and each person, if any, who controls the Company within the meaning of the Act or the Exchange Act and the Selling Shareholders against any Claim to which the Company, or any such director, officer, controlling person or the Selling Shareholders may become subject under the Act, the Exchange Act, Blue Sky Laws or other federal or state statutory laws or regulations, at common law or otherwise (including payments made in settlement of any litigation, if such settlement is effected with the written consent of such Underwriter and 52 53 Cleary Gull), insofar as such Claim arises out of or is based upon any untrue or alleged untrue statement of any material fact contained in the Registration Statement, any Preliminary Prospectus, the Prospectus, or any amendment or supplement thereto, or in any Blue Sky Application, or arises out of or is based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, any Preliminary Prospectus, the Prospectus, or any amendment or supplement thereto, or in any Blue Sky Application, in reliance solely upon and in conformity with the written information furnished by the Representative to the Company solely as specified in Section 5 of this Agreement. Each Underwriter will severally reimburse any legal fees or other expenses incurred by the Company, or any such director, officer, controlling person or the Selling Shareholders in connection with investigating or defending any such Claim, and from any and all Claims solely resulting from failure of an Underwriter to deliver a Prospectus, if the person asserting such Claim purchased Shares from such Underwriter and a copy of the Prospectus (as then amended if the Company shall have furnished any amendments thereto) was not sent or given by or on behalf of such Underwriter to such person, if required by law so to have been delivered, at or prior to the written confirmation of the sale of the Shares to such person, and if the Prospectus (as so amended) would have cured the defect giving rise to such Claim. The indemnification obligations of each Underwriter as provided above are in addition to any liabilities any such Underwriter may otherwise have. Notwithstanding the provisions of this section, no 53 54 Underwriter shall be required to indemnify or reimburse the Company, or any officer, director, controlling person or Selling Shareholders in an aggregate amount in excess of the total price at which the Shares purchased by any such Underwriter hereunder were offered to the public, less the amount of any damages such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. (c) Promptly after receipt by an indemnified party under this section of notice of the commencement of any action in respect of a Claim, such indemnified party will, if a Claim in respect thereof is to be made against an indemnifying party under this section, notify the indemnifying party in writing of the commencement thereof, but the omission so to notify the indemnifying party will not relieve an indemnifying party from any liability it may have to any indemnified party under this section or otherwise, except to the extent the indemnifying party is actually prejudiced by the failure to give such notice. In case any such action is brought against any indemnified party, and such indemnified party notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate in and, to the extent that he, she or it may wish, jointly with all other indemnifying parties, similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and any indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to the indemnified party and/or other indemnified parties which are different from or additional to those available to any 54 55 indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action 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 any claims that are the subject matter of such action. (d) Upon receipt of notice from the indemnifying party to such indemnified party of the indemnifying party's election to assume the defense of such action and upon approval by the indemnified party of counsel selected by the indemnifying party, the indemnifying party will not be liable to such indemnified party under this section for any legal fees or other expenses subsequently incurred by such indemnified party in connection with the defense thereof, unless: (i) The indemnified party shall have employed separate counsel in connection with the assumption of legal defenses in accordance with the proviso to the last sentence of subsection (c) of this Section (it being understood, however, that the indemnifying party shall not be liable for the legal fees and expenses of more than one separate counsel, approved by the Representative, if one or more of the Underwriters or their controlling persons are the indemnified parties); 55 56 (ii) The indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after the indemnified party's notice to the indemnifying party of commencement of the action; or (iii) The indemnifying party has authorized the employment of counsel at the expense of the indemnifying party. (e) If the indemnification provided for in this section is unavailable to an indemnified party under subsection (a) or (b) hereof in respect of any Claim referred to therein, then each indemnifying party, in lieu of indemnifying such indemnified party, shall, subject to the limitations hereinafter set forth, contribute to the amount paid or payable by such indemnified party as a result of such Claim: (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, the Selling Shareholders and the Underwriters from the offering of the Shares; 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 Company, the Selling Shareholders and the Underwriters in connection with the statements or omissions which resulted in such Claim, as well as any other relevant equitable considerations. 56 57 The relative benefits received by each of the Company, the Selling Shareholders and the Underwriters shall be deemed to be in such proportion so that the Underwriters are responsible for that portion represented by the percentage that the amount of the underwriting discounts and commissions per share appearing on the cover page of the Prospectus bears to the public offering price per share appearing thereon, and the Company (including its officers and directors and controlling persons), and the Selling Shareholders is responsible for the remaining portion. The relative fault of the Company, the Selling Shareholders and the Underwriters shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company, the Selling Shareholders or the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the Claims referred to above shall be deemed to include, subject to the limitations set forth in subsections (c) and (d) of this section, any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. (f) The Company, the Selling Shareholders and the Underwriters agree that it would not be just and equitable if contribution pursuant to this section were determined by pro rata or per capita allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method or allocation which does not take into account the equitable considerations referred to in subsection (e) of this Section. 57 58 Notwithstanding the other provisions of this section, no Underwriter shall be required to contribute any amount that is greater than 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 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters' obligations to contribute pursuant to this section are several in proportion to their respective underwriting commitments and not joint. 12. Default of Underwriters. It shall be a condition to the obligations of each Underwriter to purchase the Shares in the manner as described herein, that, except as hereinafter provided in this section, each of the Underwriters shall purchase and pay for all the Shares agreed to be purchased by such Underwriter hereunder upon tender to the Representative of all such Shares in accordance with the terms hereof. If any Underwriter or Underwriters default in their obligations to purchase Shares hereunder on either the Firm Closing Date or the Option Closing Date and the aggregate number of Shares which such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total number of Shares which the Underwriters are obligated to purchase on such Closing Date, the Representative may make arrangements for the purchase of such Shares by other persons, including any of the Underwriters, but if no such arrangements are made by such Closing Date the nondefaulting Underwriters shall be obligated severally, in proportion to their respective 58 59 commitments hereunder, to purchase the Shares which such defaulting Underwriters agreed but failed to purchase on such Closing Date. If any Underwriter or Underwriters so default and the aggregate number of Shares with respect to which such default or defaults occur is greater than 10% of the total number of Shares which the Underwriters are obligated to purchase on such Closing Date, and arrangements satisfactory to the Representative for the purchase of such Shares by other persons are not made within 36 hours after such default, then this Agreement will terminate without liability on the part of any nondefaulting Underwriter, the Company or the Selling Shareholders, except for the expenses to be paid by the Company and the Selling Shareholders pursuant to Section 8 hereof and except to the extent provided in Section 11 hereof. In the event that Shares to which a default relates are to be purchased by the nondefaulting Underwriters or by another party or parties, the Representative shall have the right to postpone the Firm Closing Date or the Option Closing Date, as the case may be, for not more than seven business days in order that the necessary changes in the Registration Statement, Prospectus and any other documents, as well as any other arrangements, may be effected. As used in this Agreement, the term "Underwriter" includes any person substituted for an Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default. 13. Effective Date. This Agreement shall become effective upon the execution and delivery of this Agreement by the parties hereto. Such execution and delivery shall include an executed copy of this 59 60 Agreement sent by telecopier, facsimile transmission or other means of transmitting written documents. 14. Termination. Without limiting the right to terminate this Agreement pursuant to any other provision hereof, this Agreement may be terminated by the Representative prior to or on the Firm Closing Date and the over-allotment option from the Selling Shareholders referred to in Section 3(c) hereof, if exercised, may be cancelled by the Representative at any time prior to or on the Option Closing Date, if in the judgment of the Representative, payment for and delivery of the Shares is rendered impracticable or inadvisable because: (a) Trading in the Common Stock shall have been suspended by the Commission or the New York Stock Exchange; additional restrictions, not in force and effect on the date hereof, shall have been imposed upon trading in securities generally; minimum or maximum prices shall have been established on the New York Stock Exchange, the American Stock Exchange or NASDAQ; or trading in securities generally shall have been suspended or materially limited on either such exchange or on NASDAQ; (b) A general banking moratorium shall have been established by either federal or state authorities in New York, Minnesota or Wisconsin; (c) Any event shall have occurred or shall exist which makes untrue or incorrect in any material respect any statement or information contained in the Registration Statement or which is not reflected in the Registration Statement but should be reflected therein to 60 61 make the statements or information contained therein not misleading in any material respect; or (d) An outbreak or escalation of hostilities or other national or international calamity, crisis or emergency or any substantial change in political, financial or economic conditions shall have occurred or shall have accelerated to such extent, in the judgment of the Representative, as to have a material adverse effect on the financial markets of the United States, or to make it impracticable or inadvisable to proceed with completion of the sale of and payment for the Shares as provided in this Agreement. Any termination pursuant to this Section shall be without liability on the part of any Underwriter to the Company or the Selling Shareholders, or on the part of the Company or the Selling Shareholders to any Underwriter, except for expenses to be paid by the Company and/or the Selling Shareholders pursuant to Section 8 hereof or reimbursed by the Company and/or the Selling Shareholders pursuant to Section 7(f) hereof and except as to indemnification to the extent provided in Section 11 hereof. 15. Representations and Indemnities to Survive Delivery. The respective indemnities, agreements, representations, warranties, covenants and other statements of the Company, of its officers or directors, of the Selling Shareholders and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, the Selling Shareholders or the Company or any of its or their partners, 61 62 officers, directors or any controlling person, as the case may be, and will survive delivery of and payment for the Shares sold hereunder. 16. Notices. All communications hereunder will be in writing and, if sent to the Representative, will be mailed, delivered, telecopied (with receipt confirmed) or telegraphed and confirmed to Cleary Gull Reiland & McDevitt Inc. at 100 East Wisconsin Avenue, Milwaukee, Wisconsin 53202, Attention: Joseph F.

Lederman, Esq., Maslon Edelman Borman & Brand, 3300 Norwest Center, 90 South Seventh Street, Minneapolis, MN 55402-4140. 17. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors, personal representatives and assigns, and to the benefit of the officers and directors and controlling persons referred to in Section 11 hereof and no other person will have any right or obligation hereunder. The term 62 63 "successors" shall not include any purchaser of the Shares as such from any of the Underwriters merely by reason of such purchase. 18. Partial Unenforceability. If any section, paragraph, clause or provision of this Agreement is for any reason determined to be invalid or unenforceable, such determination shall not affect the validity or enforceability of any other section, paragraph clause or provision hereof. 19. Applicable Law; Counterparts. This Agreement shall be governed by and construed in accordance with the internal laws of the State of Wisconsin without reference to conflict of law principles thereunder. This Agreement may be signed in various counterparts which together shall constitute one and the same instrument, and shall be effective when at least one counterpart hereof shall have been executed by or on behalf of each party hereto.
