2010 INCENTIVE COMPENSATION PLAN

NON-QUALIFIED STOCK OPTION AGREEMENT

In accordance with and subject to the terms of the Associated Banc-Corp 2010 Incentive Compensation Plan (the “Plan”) and this Agreement, the Committee granted to the person named as grantee (the “Grantee”) on the cover page attached to this Non-Qualified Stock Option Agreement (the “Cover Page”) an option to purchase shares of common stock, par value $0.01 per share, of the Company (the Cover Page and this Non-Qualified Stock Option Agreement hereinafter referred to as the “Agreement”).

To evidence the Option and to set forth its terms, the Company and the Grantee agree as follows. All capitalized terms used, but otherwise not defined herein, shall have the meanings set forth in the Plan.

1. Grant of Option. Subject to and upon the terms and conditions set forth in this Agreement and the Plan, the Committee granted to the Grantee an option (the “Option”) to purchase the number of shares of Common Stock set forth on the Cover Page (subject to adjustment as provided in Section 4.2 of the Plan), effective as of the grant date set forth on the Cover Page (the “Grant Date”), and the Grantee hereby accepts the grant of the Option as set forth herein. The Option granted hereby is not intended to constitute an Incentive Stock Option, within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended.

2. Option Price. The purchase price of this Option shall be equal to the per-Share price set forth on the Cover Page (the “Option Price”) (subject to adjustment as provided in Section 4.2 of the Plan). The Option Price is equal to 100% of the Fair Market Value of one Share of Common Stock on the Grant Date.

3. Term and Vesting of the Option. The Option’s Term shall expire on the tenth anniversary of the Grant Date, and, except as otherwise provided herein, any portion of this Option may be exercised upon or following the date on which such portion vests, as long as such exercise occurs prior to the expiration of this Option as provided in this Agreement and the Plan. Subject to Paragraphs 4 and 5 below, this Option shall vest in accordance with the following schedule:

Notwithstanding the foregoing provisions of this Paragraph 3, and except as otherwise determined by the Committee, as provided in the Plan or as provided herein, any portion of this Option that is not vested (or otherwise not exercisable) at the time of the Grantee’s Termination of Service shall not become exercisable after such termination and shall be immediately cancelled and forfeited to the Company.

1

4. Termination of Service. Subject to Paragraph 5 below, the provisions of this Paragraph 4 shall apply in the event the Grantee incurs a Termination of Service at any time prior to this Option becoming fully vested pursuant to Paragraph 3 above:

(a) If the Grantee incurs a Termination of Service because of his or her Early Retirement or Normal Retirement, (i) any unvested portion of this Option shall be immediately forfeited to the Company, and (ii) any vested and exercisable portion of this Option shall remain exercisable for one year following such Termination of Service. Any such vested portion of this Option that is not exercised prior to the end of such one-year period shall be forfeited to the Company.

(b) If the Grantee incurs a Termination of Service because of his or her death or Disability, this Option shall (i) become fully vested and exercisable and (ii) remain exercisable for one year following such Termination of Service. Any portion of this Option that is not exercised prior to the end of such one-year period shall be forfeited to the Company.

(c) If the Grantee incurs a Termination of Service by an Employer without Cause or voluntarily on his or her part (but not on account of the Grantee’s death, Disability, Early Retirement or Normal Retirement), (i) any vested portion of this Option shall remain exercisable for 30 days following such Termination of Service and (ii) any unvested portion of this Option shall be immediately forfeited to the Company. Any portion of this Option that is not exercised prior to the end of such 30-day period shall be forfeited to the Company.

(d) If the Grantee incurs a Termination of Service for Cause, this Option shall be immediately forfeited to the Company.

5. Change in Control. Notwithstanding Paragraph 4 above, if the Grantee incurs an involuntary Termination of Service (other than due to Cause) during the two year period immediately following a Change in Control, any unvested portion of this Option prior to the date of such Termination of Service shall become vested and exercisable, and this Option shall remain exercisable for 30 days following such Termination of Service. Any portion of this option that is not exercised prior to the end of such 30-day period shall be forfeited to the Company. In addition, upon a Change in Control, the Grantee will have such rights with respect to this Option as are provided for in the Plan.

6. Exercise of Option. On or after the date any portion of this Option becomes exercisable, but prior to the expiration of this Option in accordance with Paragraphs 3, 4 or 5 above, the portion of this Option that has become exercisable may be exercised in whole or in part by the Grantee (or, pursuant to this Paragraph 6, by his or her permitted successor) upon delivery of the following to the Company:

(a) a written notice of exercise which identifies this Agreement and states the number of whole Shares then being purchased; and

(b) any combination of cash (or by personal check or wire transfer payable to the Company), and/or (i) with the approval of the Committee, Shares or Shares of Restricted Stock then owned by the Grantee in an amount having a combined Fair Market Value on the exercise date equal to the aggregate Option Price of the Shares then being purchased, or

2

(ii) unless otherwise prohibited by law or Company policy, an irrevocable authorization of a third party to sell Shares acquired upon the exercise of this Option and prompt remittance to the Company of a sufficient portion of the sale proceeds to pay the entire Option Price and any tax withholdings resulting from such exercise.

Notwithstanding the foregoing, the Grantee (or any permitted successor) shall take whatever additional actions, including, without limitation, the furnishing of an opinion of counsel, and execute whatever additional documents the Company may, in its sole discretion, deem necessary or advisable in order to carry out or effect one or more of the obligations or restrictions imposed by the Plan, this Agreement or applicable law.

No Shares shall be issued upon exercise of this Option until full payment has been made. Upon satisfaction of the conditions and requirements of this Paragraph 6 and the Plan, the Company shall credit, in a book entry on the records kept by the Company’s transfer agent, the number of Shares in respect of which this Option shall have been exercised. Upon exercise of this Option (or a portion thereof), the Company shall have a reasonable time to so credit the Common Stock for which this Option has been exercised, and the Grantee shall not be treated as a shareholder for any purposes whatsoever prior to such credit. No adjustment shall be made for cash dividends or other rights for which the record date is prior to the date such Common Stock is recorded as issued and transferred in book entry of the Company’s transfer agent, except as otherwise provided in the Plan or this Agreement. As a further condition to the Company’s obligations under this Agreement, the Company may require the Grantee’s spouse (if any) to execute and deliver to the Company the Consent of Spouse attached hereto as Exhibit A.

7. Limitation Upon Transfer. This Option and all rights granted hereunder shall not (a) be transferred by the Grantee, other than by will, by the laws of descent and distribution, or to a Permitted Transferee; (b) be otherwise assigned, pledged or hypothecated in any way; and (c) be subject to execution, attachment or similar process. Any attempt to transfer this Option, other than by will or by the laws of descent and distribution or to a Permitted Transferee, or to assign, pledge, hypothecate or otherwise dispose of this Option or of any rights granted hereunder contrary to the provisions hereof, or upon the levy of any attachment or similar process upon this Option or such rights, shall be void and unenforceable against the Company or any Subsidiary; provided, however, that the Grantee may designate a Beneficiary to receive benefits in the event of the Grantee’s death. This Option shall be exercised during the Grantee’s lifetime only by the Grantee, the Grantee’s guardian, the Grantee’s legal representative or a Permitted Transferee.

8. Restrictive Covenants.

(a) Confidential Information. The parties hereto acknowledge that the Company has created and maintains at great expense strategic plans, sales data and sales strategy, methods, products, procedures, processes, techniques, financial information, customer and supplier lists, personal customer data, pricing policies, personnel data and other similar confidential and proprietary information, and has received from its customers certain confidential and proprietary information (collectively, the “Confidential Information”). The parties hereto further acknowledge that the Company has taken and will continue to take actions to protect the Confidential Information. Accordingly, the Grantee agrees that during the term of the Grantee’s

3

employment with the Company, and until the sooner of (i) such time as the Confidential Information becomes generally available to the public through no fault of the Grantee or other person under the duty of confidentiality to the Company, (ii) such time as the Confidential Information no longer provides a benefit to the Company, or (iii) two (2) years after the termination of the Grantee’s employment with the Company, the Grantee will not, in any capacity, use or disclose, or cause to be used or disclosed, in any geographic territory in which the Company or any of the Company’s customers do business, any Confidential Information the Grantee acquired while employed by the Company. The requirements of confidentiality and the limitations on use and disclosure described in this Agreement shall not apply to Confidential Information that the Grantee can demonstrate by clear and convincing evidence, at the time of disclosure by the Company to the Grantee, was known to the Grantee as evidenced by the Grantee’s contemporaneous written records. The parties hereto agree that nothing in this Agreement shall be construed to limit or negate the law of torts or trade secrets where it provides the Company with broader protection than that provided herein.

(b) Return of Company Property. The parties hereto acknowledge that any material (in computerized or written form) that the Grantee obtained in the course of performing the Grantee’s employment duties are the sole and exclusive property of the Company, the Grantee agrees to immediately return any and all records, files, computerized data, documents, confidential or proprietary information, or any other property owned or belonging to the Company in the Grantee’s possession or under his or her control, without any originals or copies being kept by the Grantee or conveyed to any other person, upon the Grantee’s separation from employment or upon the Company’s request.

(c) Non-Interference with Customers, Employees. For a period of six (6) months following the termination of the Grantee’s employment with the Company for any reason, the Grantee will not, directly or indirectly, on behalf of him/herself or any other person, entity or enterprise, do any of the following:

(i) solicit or accept business from any person or entity who is an Active Customer (as defined below) of the Company, a Subsidiary, or any of their affiliates, with whom the Grantee has had business contact during the twelve (12) month period prior to the termination of the Grantee’s employment with the Company (the “Reference Period”) for the purpose of providing competitive products or services similar to those provided by the Grantee during the Reference Period;

(ii) request or advise any of the Active Customers, suppliers or other business contacts of the Company who have business relationships with the Company and with whom the Grantee had business contact during his/her employment with the Company to withdraw, curtail or cancel any of their business relations with the Company;

(iii) induce or attempt to induce any employee or other personnel of the Company to terminate his or her relationship or breach his/her employment relationship or other contractual relationship, whether oral or written, with the Company; provided, however, that nothing shall prevent a future employer of the Grantee from hiring such employee or other personnel if the Grantee does not otherwise violate this provision.

4

“Active Customer” shall mean any customer or prospective customer of the Company which, within the Reference Period, either received any products or services supplied by or on behalf of the Company or was the recipient of at least two (2) business contacts by any personnel of the Company (including the Grantee).

(e) Remedies. Notwithstanding any other provision of this Agreement, if the Grantee breaches any provision of this Paragraph 8, the Option shall be immediately forfeited to the Company. In addition, the Company shall be entitled to injunctive and other equitable relief (without the necessity of showing actual monetary damages or of posting any bond or other security): (i) restraining and enjoining any act which would constitute a breach, or (ii) compelling the performance of any obligation which, if not performed, would constitute a breach, as well as any other remedies available to the Company, including monetary damages. Upon the Company’s request, the Grantee shall provide reasonable assurances and evidence of compliance with the restrictive covenants set forth in this Paragraph 8. If any court of competent jurisdiction shall deem any provision in this Paragraph 8 too restrictive, the other provisions shall stand, and the court shall modify the unduly restrictive provision to the point of greatest restriction permissible by law. The restrictive covenants set forth in this Paragraph 8 shall survive the termination of this Agreement, the forfeiture of the Option, and the Grantee’s termination of employment for any reason, and the Grantee shall continue to be bound by the terms of this Paragraph 8 as if this Agreement was still in effect.

9. Liability of the Company. The inability of the Company to obtain approval from any regulatory body having authority deemed by the Company to be necessary to the lawful issuance and transfer of any Shares pursuant to this Agreement shall relieve the Company of any liability with respect to the non-issuance or transfer of the Shares as to which such approval shall not have been obtained. However, the Company shall use commercially reasonable efforts to obtain all such approvals.

10. Adjustment in Option. This Option is subject to adjustment as provided under Section 4.2 of the Plan.

11. Plan and Agreement Amendment.

(a) No discontinuation, modification, or amendment of the Plan may, without the written consent of the Grantee, adversely affect the rights of the Grantee under this Agreement, except as otherwise provided under the Plan.

(b) This Agreement may be amended as provided under the Plan, but no such amendment shall adversely affect the Grantee’s rights under this Agreement without the Grantee’s written consent, unless otherwise permitted by the Plan.

12. Shareholder Rights. The Grantee shall have the rights of a shareholder with respect to the Shares subject to this Option only upon becoming the holder of such Shares.

13. Employment Rights. This Agreement is not a contract of employment, and the terms of employment of the Grantee or other relationship of the Grantee with an Employer shall not be affected in any way by this Agreement except as specifically provided herein. The execution of this Agreement shall not be construed as conferring any legal rights upon the

5

Grantee for a continuation of an employment or other relationship with an Employer, nor shall it interfere with the right of an Employer to discharge the Grantee and to treat him or her without regard to the effect which such treatment might have upon him or her as a Grantee.

14. Disclosure Rights. Except as required by applicable law, the Company (or any of its affiliates) shall not have any duty or obligation to disclose affirmatively to a record or beneficial holder of Common Stock or an option to purchase such stock, and such holder shall have no right to be advised of, any material information regarding the Company at any time prior to, upon or in connection with receipt of the Shares.

15. Governing Law. This Agreement shall be governed by the internal substantive laws, but not the choice of law rules, of the State of Wisconsin. This Agreement, subject to the terms and conditions of the Plan, represents the entire agreement between the parties with respect to the grant of this Option to the Grantee. The parties hereto each submit and consent to the jurisdiction of the courts in the State of Wisconsin, Brown County, in any action brought to enforce or otherwise relating to this Agreement.

16. Compliance with Laws and Regulations. Notwithstanding anything herein to the contrary:

(b) the Company may require, as a condition of such a book entry, and in order to ensure compliance with such laws, regulations and requirements, that the Grantee make whatever covenants, agreements, and representations, or execute whatever documents or instruments, the Company, in its sole discretion, considers necessary or desirable;

(c) no payment or benefit under this Agreement shall be provided to the Grantee if it would violate any applicable Compensation Limitation; and

(d) Notwithstanding anything to the contrary in this Agreement, the Option (including any proceeds, gains, or other economic benefit actually or constructively received by the Grantee thereof upon the receipt, vesting, or exercise thereof, or the receipt or resale of Shares upon or after exercise of this Award) shall be subject to the provisions of any clawback or recoupment policy adopted by the Board and/or the Committee, including any such policy adopted to comply with the Dodd-Frank Wall Street Reform and Consumer Protection Act, any rules or regulations promulgated and in effect thereunder, or any SEC or securities exchange rule.

17. Successors and Assigns. Except as otherwise expressly set forth in this Agreement, the provisions of this Agreement shall inure to the benefit of, and be binding upon, the succeeding administrators, heirs and legal representatives of the Grantee and the successors and assigns of the Company.

18. No Limitation on Rights of the Company.

The interpretation and construction by the Committee of the Plan, this Agreement and any such rules and regulations adopted by the Committee for purposes of administering the Plan shall be final and binding upon the Grantee and all other persons.

21. Entire Agreement. This Agreement, together with the Plan, constitutes the entire obligation of the parties hereto with respect to the subject matter hereof and shall supersede any prior expressions of intent or understanding with respect to this transaction.

22. Waiver; Cumulative Rights. The failure or delay of either party to require performance by the other party of any provision hereof shall not affect its right to require performance of such provision unless and until such performance has been waived in writing. Each and every right hereunder is cumulative and may be exercised in part or in whole from time to time.

23. Counterparts. This Agreement may be signed in two counterparts, each of which shall be an original, but both of which shall constitute but one and the same instrument.

24. Headings. The headings contained in this Agreement are for reference purposes only and shall not affect the meaning or interpretation of this Agreement.

25. Severability. If any provision of this Agreement shall for any reason be held to be invalid or unenforceable, such invalidity or unenforceability shall not affect any other provision hereof, and this Agreement shall be construed as if such invalid or unenforceable provision were omitted.
