The Company also proposes to issue and sell to the Underwriter up to an additional 630,000 shares of common stock, par value $0.01 per share, of the Company (the “Additional Shares”), if and to the extent that the Underwriter shall have determined to exercise the right to purchase such shares of common stock granted to the Underwriter in Section 2 hereof. The Firm Shares and the Additional Shares are hereinafter collectively referred to as the “Shares.” The shares of Common Stock ($0.01 par value per share) of the Company to be outstanding after giving effect to the sales contemplated hereby are hereinafter referred to as the “Common Stock.”

The Company has prepared and filed, in accordance with the Securities Act of 1933, as amended (the “Securities Act”), and the rules and regulations thereunder, with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (file number 333-147511), including a prospectus, relating to the Shares, which registration statement and prospectus incorporate or are deemed to incorporate by reference documents that the Company has filed, or will file, with the Commission in accordance with the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations thereunder. The registration statement as amended at the time it became effective for purposes of Section 11 of the Securities Act (as such section applies to the Underwriter), including the documents filed as part thereof and information contained or incorporated by reference in the prospectus or otherwise deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430A or Rule 430B under the Securities Act, is hereinafter referred to as the “Registration Statement.” If the Company files an abbreviated registration statement to register additional shares of Common Stock pursuant to Rule 462(b) under the Securities Act (the “Rule 462 Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462 Registration Statement. The Company has also filed with, or transmitted for filing to, or shall promptly after the date of this Agreement file with or transmit for filing to, the Commission a prospectus supplement (in the form first used to confirm sales of the Shares (or in the form first made available to the Underwriter by the Company to meet requests of purchasers pursuant to Rule 173 under the Securities Act), the “Prospectus Supplement”) pursuant to Rule 424 under the Securities Act. The

term “Base Prospectus” means the prospectus dated December 3, 2007, relating to the Shares, in the form in which it has most recently been filed with the Commission as part of the Registration Statement on or prior to the date of this Agreement. The term “Prospectus” means the Base Prospectus as supplemented by the Prospectus Supplement. The term “Preliminary Prospectus” means any preliminary form of Prospectus, including, without limitation, the preliminary Prospectus Supplement dated April 13, 2010 filed with the Commission pursuant to Rule 424 (the “Preliminary Prospectus Supplement”).

For purposes of this Agreement, “free writing prospectus” has the meaning set forth in Rule 405 under the Securities Act; “Time of Sale Prospectus” means the Base Prospectus and the Preliminary Prospectus, together with the free writing prospectuses, if any, each identified in Schedule II hereto (each, a “Permitted Free Writing Prospectus”), and other information conveyed to purchasers of the Shares at or prior to the Time of Sale as set forth in Schedule II hereto; “Time of Sale” means 9:00 p.m. (Central Time) on the date of this Agreement; and “road show” has the meaning set forth in Rule 433(h)(4) under the Securities Act. As used herein, the terms “Registration Statement,” “Base Prospectus,” “Preliminary Prospectus,” “Time of Sale Prospectus” and “Prospectus” shall include the documents, if any, deemed to be incorporated by reference therein, including, unless the context otherwise requires, the documents, if any, filed as exhibits to such incorporated documents. The terms “supplement,” “amendment” and “amend” as used herein with respect to the Registration Statement, the Base Prospectus, any Preliminary Prospectus, the Time of Sale Prospectus, the Prospectus or any free writing prospectus shall include all documents subsequently filed by the Company with the Commission pursuant to the Exchange Act that are deemed to be incorporated by reference therein.

in the underwriter table, under the heading “Offering Price”, the first two sentences under the heading “Commissions and Expenses” and under the heading “Stabilization” in the “Underwriting” section of the Prospectus Supplement and the Preliminary Prospectus Supplement.

(d) Prior to the execution of this Agreement, the Company has not, directly or indirectly, offered or sold any Shares by means of any “prospectus” (within the meaning of the Securities Act) or used any “prospectus” (within the meaning of the Securities Act) in connection with the offer or sale of the Shares, in each case other than the Preliminary Prospectus Supplement and/or the Permitted Free Writing Prospectuses; the Company has not, directly or indirectly, prepared, used or referred to any free writing prospectuses, without the prior written consent of the Underwriter, other than the Permitted Free Writing Prospectuses and Road Show Information furnished or presented to the Underwriter before first use.

(jj) Except as described in the Time of Sale Prospectus and the Prospectus, the Company is not a party to any contract, agreement or understanding with any person (other than this Agreement) that would give rise to a valid claim against the Company or the Underwriter for a brokerage commission, finder’s fee or like payment in connection with the offering and sale of the Shares.

The Company hereby agrees to issue and sell 4,200,000 Firm Shares to the Underwriter at a price of $4.23 per share (the “Purchase Price”), and the Underwriter, upon the basis of the representations and warranties herein contained, but subject to the conditions herein set forth, agrees to purchase from the Company at the Purchase Price the Firm Shares.

Moreover, the Company hereby agrees to issue and sell up to 630,000 Additional Shares to the Underwriter at the Purchase Price, and the Underwriter, upon the basis of the representations and warranties contained herein, but subject to the terms and conditions herein set forth, shall have the right (but not the obligation) to purchase up to the Additional Shares at the Purchase Price. The Underwriter may exercise this right in whole or from time to time in part by giving written notice not later than 30 days after the date of this Agreement. Any exercise notice shall specify the number of Additional Shares to be purchased by the Underwriter and the date on which such shares are to be purchased. Each purchase date must be at least one business day after the written notice is given and may not be earlier than the closing date for the Firm Shares or later than ten business days after the date such notice is given. Additional Shares may be purchased as provided in Section 4 hereof solely for the purpose of covering over-allotments made in connection with the offering of the Firm Shares. On each day, if any, that Additional Shares are to be purchased (an “Option Closing Date”), the Underwriter agrees to purchase the number of Additional Shares set forth in the exercise notice.

3. Terms of Public Offering. The Company is advised by the Underwriter that the Underwriter proposes to make a public offering of the Shares as soon after

this Agreement has become effective as in the Underwriter’s judgment is advisable. The Company is further advised by the Underwriter that the Shares are to be offered to the public initially at $4.50 per share (the “Public Offering Price”) and to certain dealers selected by the Underwriter at a price that represents a concession not in excess of $0.1458 per share under the Public Offering Price, and that the Underwriter may allow, and such dealers may reallow a concession, not in excess of $0.10 per share, to the Underwriter or to certain other dealers.

4. Payment and Delivery. Payment for the Firm Shares to be sold by the Company shall be made to the Company in Federal or other funds immediately available in Milwaukee, Wisconsin against delivery of such Firm Shares for the account of the Underwriter at 10:00 a.m., Central Time, on April 19, 2010 or at such other time on the same or such other date, not later than April 26, 2010, as shall be designated in writing by the Underwriter. The time and date of such payment are hereinafter referred to as the “Closing Date.”

Payment for any Additional Shares shall be made to the Company in Federal or other funds immediately available in Milwaukee, Wisconsin against delivery of such Additional Shares for the account of the Underwriter at 10:00 a.m., Central Time, on the date specified in the corresponding notice described in Section 2 or at such other time on the same or on such other date, in any event not later than ten business days after the expiration of the notice as shall be designated in writing by the Underwriter.

The Firm Shares and Additional Shares shall be delivered to the Underwriter on the Closing Date or an Option Closing Date, as the case may be, for the account of the Underwriter, with any transfer taxes payable in connection with the transfer of the Shares to the Underwriter duly paid, against payment of the Purchase Price therefor.

(e) To advise the Underwriter promptly of any request by the Commission for amendments or supplements to the Registration Statement, the Base Prospectus, any Preliminary Prospectus, any Permitted Free Writing Prospectus, any Prospectus Supplement or the Prospectus or for additional information with respect thereto, or of notice of institution of proceedings for, or the entry of a stop order, suspending the effectiveness of the Registration Statement or preventing or suspending the use of any Preliminary Prospectus, the Time of Sale Prospectus or the Prospectus; and if the Commission should enter such a stop order, to use its best efforts to obtain the lifting or removal of such order as soon as possible.

(f) If the Time of Sale Prospectus is being used to solicit offers to buy the Shares at a time when the Prospectus is not yet available to prospective purchasers and any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Time of Sale Prospectus in order to make the statements therein, in the light of the circumstances, not misleading, or if any event shall occur or condition exist as a result of which the Time of Sale Prospectus conflicts with the information contained in the Registration Statement then on file, or if, in the opinion of counsel for the Underwriter, it is necessary to amend or supplement the Time of Sale Prospectus to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriter and to any dealer upon request, either amendments or supplements to the Time of Sale Prospectus so that the statements in the Time of Sale Prospectus as so amended or supplemented will not, in the light of the circumstances when delivered to a prospective purchaser, be misleading or so that the Time of Sale

Prospectus, as amended or supplemented, will no longer conflict with the Registration Statement, or so that the Time of Sale Prospectus, as amended or supplemented, will comply with applicable law.

(g) If, during such period after the first date of the public offering of the Shares as in the opinion of counsel for the Underwriter after consultation with counsel for the Company the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) under the Securities Act) is required by law to be delivered in connection with sales by the Underwriter or a dealer, any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) under the Securities Act) is delivered to a purchaser, not misleading, or if, in the opinion of counsel for the Underwriter after consultation with counsel for the Company, it is necessary to amend or supplement the Prospectus to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriter and to any dealers (whose names and addresses the Underwriter will furnish to the Company) to which Shares may have been sold by the Underwriter and to any other dealers upon request, either amendments or supplements to the Prospectus so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) under the Securities Act) is delivered to a purchaser, be misleading or so that the Prospectus, as amended or supplemented, will comply with applicable law.

(h) If, at the time this Agreement is executed and delivered, it is necessary or appropriate for a post-effective amendment to the Registration Statement, or a Registration Statement under Rule 462(b) under the Securities Act, to be filed with the Commission and become effective before the Shares may be sold, the Company will use its best efforts to cause such post-effective amendment or such Registration Statement to be filed and become effective, and will pay any applicable fees in accordance with the Securities Act, as soon as possible; and the Company will advise the Underwriter promptly and, if requested by the Underwriter, will confirm such advice in writing, (i) when such post-effective amendment or such Registration Statement has become effective, and (ii) if Rule 430A under the Securities Act is used, when the Prospectus is filed with the Commission pursuant to Rule 424(b) under the Securities Act (which the Company agrees to file in a timely manner in accordance with such Rules).

(i) If, at any time during the period when a prospectus is required by the Securities Act to be delivered (whether physically or through compliance with Rule 172 under the Securities Act or any similar rule) in connection with any sale of Shares, the Registration Statement shall cease to comply with the requirements of the Securities Act with respect to eligibility for the use of the form on which the Registration Statement was filed with the Commission, to (i) promptly notify the Underwriter, (ii) promptly file with the Commission a new registration statement under the Securities Act, relating to the Shares, or a post-effective amendment to the Registration Statement, which new registration statement or post-effective amendment shall comply with the requirements of the Securities Act and shall be in

(l) Promptly to furnish such information or to take such action as the Underwriter may reasonably request and otherwise to qualify the Shares for offer and sale under the securities or “blue sky” laws of such jurisdictions as the Underwriter shall reasonably request, and to comply with such laws so as to permit the continuance of sales and dealings therein in such jurisdictions for as long as may be necessary to complete the distribution of the Shares; provided, however, that the Company shall not be required to qualify as a foreign corporation, to file a consent to service of process in any jurisdiction (excluding service of process with respect to the offer and sale of the Shares), or to subject itself to taxation in any jurisdiction in which it would not otherwise be subject; and to promptly advise the Underwriter of the receipt by the Company of any notification with respect to the suspension of the qualification of the Shares for offer or sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose.

(m) To make generally available to the Company’s security holders and to the Underwriter as soon as practicable an earning statement covering a period of at least twelve months beginning after the effective date of the Registration Statement (as defined in Rule 158(c) under the Securities Act), which shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder.

(r) Not to take, directly or indirectly, any action designed, or which will constitute, or has constituted, or might reasonably be expected to cause or result in the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Shares.

(s) Not, at any time at or after the execution of this Agreement, to offer or sell any Shares by means of any “prospectus” (within the meaning of the Securities Act) or use any “prospectus” (within the meaning of the Securities Act) in connection with the offer or sale of the Shares, except in each case other than the Prospectus.

8. Indemnity and Contribution. (a) The Company agrees to indemnify and hold harmless the Underwriter, each person, if any, who controls the Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each affiliate of the Underwriter within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by, arising out of or based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Time of Sale Prospectus, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any issuer information that the Company has filed, or is required to file, pursuant to Rule 433(d) of the Securities Act, any Road Show Information not constituting a free writing prospectus, or the Prospectus or any amendment or supplement thereto, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which there were made, not misleading; provided, however, that the Company shall

not be liable under this Section 8(a) to the extent that such losses, claims, damages or liabilities are caused by, arise out of or are based upon any such untrue statement or omission or alleged untrue statement or omission made therein in reliance upon and in conformity with information relating to the Underwriter furnished to the Company in writing by the Underwriter expressly for use therein.

(b) The Underwriter agrees to indemnify and hold harmless the Company, the directors of the Company, the officers of the Company who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by, arising from or based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Time of Sale Prospectus, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) of the Securities Act, any road show not constituting a free writing prospectus, or the Prospectus or any amendment or supplement thereto, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which there were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or omission or alleged untrue statement or omission was made therein in reliance upon and in conformity with information relating to the Underwriter furnished to the Company in writing by the Underwriter expressly for use therein.

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 8(a) or 8(b), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be, in the reasonable judgment of counsel to the indemnified party, inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in

connection with any proceeding or related proceedings in the same jurisdiction, be liable for (i) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Underwriter and all persons, if any, who control the Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or who are affiliates of the Underwriter within the meaning of Rule 405 under the Securities Act, and (ii) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either such Section, and that all such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Underwriter and such control persons and affiliates of the Underwriter, such firm shall be designated in writing by the Underwriter. In the case of any such separate firm for the Company, and such directors, officers and control persons of the Company, such firm shall be designated in writing by the Company. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(d) To the extent the indemnification provided for in 8(a) or 8(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party or parties on the other hand 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 indemnifying party or parties on the one hand and of the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriter on the other hand in connection with the offering of the Shares

shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriter, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate Public Offering Price of the Shares. The relative fault of the Company on the one hand and the Underwriter on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriter and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) The Company and the Underwriter agree that it would not be just or equitable if contribution pursuant to this Section 8 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in Section 8(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 8(d) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8, the Underwriter shall not 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 that the 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 Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(f) The indemnity and contribution provisions contained in this Section 8 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of the Underwriter, any person controlling the Underwriter or any affiliate of the Underwriter, or the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Shares.

9. Termination. The Underwriter may terminate this Agreement by notice given by the Underwriter to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (a) trading generally shall have been suspended or materially limited or minimum prices shall have been established on, or by, as the case may be, any of the New York Stock Exchange, the NYSE Amex, or NASDAQ, (b) trading of any securities of the Company shall have been suspended or materially limited on any exchange or in any over-the-counter market, (c) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (d) any moratorium or material limitation on commercial banking activities shall have been declared by Federal, Wisconsin or

New York state authorities, (e) there shall have occurred any outbreak or escalation of hostilities, act of terrorism involving the United States or declaration by the United States of a national emergency or war, or (f) any other calamity or crisis or any change in financial, political or economic conditions in the United States or elsewhere, if the effect of any such event specified in clause (e) or (f), makes it, in the Underwriter’s judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Shares on the terms and in the manner contemplated in the Time of Sale Prospectus or the Prospectus (exclusive of any supplement thereto).

10. Effectiveness. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company and the Underwriter set forth or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of the Underwriter or the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Shares. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement.

12. Entire Agreement. (a) This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Shares, represents the entire agreement between the Company, on the one hand, and the Underwriter, on the other, with respect to the preparation of any Preliminary Prospectus, the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Shares.

(b) The Company acknowledges that in connection with the offering of the Shares: (i) the Underwriter has acted at arm’s length and is not an agent of, and owes no fiduciary duties to, the Company or any other person in respect of the transactions contemplated by this Agreement irrespective of whether the Underwriter has advised or is advising the Company on other matters; (ii) the Underwriter owes the Company only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any; (iii) the Underwriter may have interests that differ from those of the Company; and (iv) the Purchase Price and the Public Offering Price of the Shares set forth in this Agreement were established and agreed to by the Company following arm’s length discussions with the Underwriter, and the Company understands and accepts the terms, risks and conditions of the transactions contemplated by this Agreement. The Company waives to the full extent permitted by applicable law any claims it may have against the Underwriter arising from an alleged breach of fiduciary duty in connection with the offering of the Shares.

13. Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which shall be deemed to be an original, but all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart by facsimile or

electronic transmission shall be equally as effective as delivery of an original counterpart of this Agreement. The failure by a party to deliver an original executed counterpart to this Agreement shall not affect the validity, enforceability and binding effect of this Agreement.

14. Applicable Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of Wisconsin.

15. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

16. Amendments or Waivers. No amendment or waiver of any provision of this Agreement or any exhibit or schedule hereto (including, without limitation, the matters disclosed on Exhibit C or Exhibit D hereto), nor any consent or approval to any departure therefrom, shall in any event be effective unless the same shall be in writing and signed by both of the parties hereto.
