The Agreement is described in further detail in Item 6 hereof, which description is incorporated herein by reference.

Item 5 of the Schedule 13D is hereby amended and restated as follows:

(a) The aggregate percentage of Shares reported owned by each person named herein is based upon 7,506,757 Shares outstanding as of October 29, 2012, according to the Issuer’s Quarterly Report on Form 10-Q, for the quarterly period ended September 30, 2012, filed with the Commission on November 2, 2012.

As of the close of business on March 4, 2013, Atlas Fund directly owned 671,685 Shares, constituting approximately 8.95% of the Shares outstanding; Master Fund directly owned 31,801 Shares, constituting approximately 0.42% of the Shares outstanding; and Mr. Walsh directly owned 39,000 Shares, constituting 0.52% of the Shares outstanding.

Mr. Walsh, by virtue of his relationship to each of the other Reporting Persons and his direct beneficial ownership of 39,000 Shares, may be deemed to beneficially own, in the aggregate, 742,486 Shares, representing approximately 9.89% of the Issuer’s outstanding Shares.

PW Capital Management, by virtue of its relationship to each of Atlas Fund and Master Fund, may be deemed to indirectly beneficially own the 703,486 Shares that Atlas Fund and Master Fund directly beneficially own in the aggregate.

Master Fund GP, by virtue of its relationship to Master Fund, may be deemed to indirectly beneficially own the 31,801 Shares that Master Fund directly beneficially owns.

(d) No person other than the Reporting Persons is known to have the right to receive, or the power to direct the receipt of dividends from, or proceeds from the sale of, the Shares.

(e) Not applicable.

The filing of this Schedule 13D shall not be construed as an admission that the Reporting Persons are, for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended, the beneficial owners of any of the Shares reported herein. Each of the Reporting Persons specifically disclaims beneficial ownership of the Shares reported herein that are not directly owned by such Reporting Person.

Item 6 of the Schedule 13D is hereby amended by the addition of the following information:

On March 1, 2013, the Issuer entered into the Agreement with the Reporting Persons. Pursuant to the Agreement, Atlas Fund has withdrawn its letter previously submitted to the Issuer stating its intention to nominate Patrick Walsh for election to the Board of Directors at the Issuer’s 2013 annual shareholders’ meeting, and the Issuer has agreed to include Mr. Walsh in the Issuer’s slate of director nominees for election at that meeting. Due to a recent change in Issuer management, one of the Issuer’s existing directors, Christopher O’Donnell, will not be standing for re-election at the 2013 annual shareholders’ meeting and Mr. Walsh will be nominated to fill that position. If elected, Mr. Walsh will be appointed to serve on the Issuer’s Audit and Strategic Planning Committees.

If a vacancy on the Board of Directors is created as a result of Mr. Walsh’s death, resignation, disqualification or removal prior to ten days before the deadline for shareholders to submit director nominations for the Issuer’s 2014 annual shareholders’ meeting, the Issuer has agreed to work in good faith with the Reporting Persons to appoint a mutually acceptable replacement so long as the Reporting Persons then own at least 5% of the Issuer’s outstanding stock. The Issuer’s nomination obligations under the Agreement will cease, and Mr. Walsh (or his replacement) must offer to resign from the Board of Directors, if the Reporting Persons cease to hold at least 5% of the Issuer’s common stock.

The Reporting Persons have agreed to standstill restrictions prohibiting them from acquiring, offering or proposing to acquire, or agreeing to acquire, directly or indirectly, any securities of the Issuer that would result in the Reporting Persons owning more than 12.9% of the Issuer’s shares or engaging in various proxy or other solicitation activities. The standstill restrictions do not limit actions that Mr. Walsh (or his replacement) may take acting solely as a director of the Issuer consistent with fiduciary duties as a director. The standstill provisions will continue until the date that is ten days prior to the deadline for shareholders to submit director nominations for the Issuer’s 2014 annual shareholders’ meeting (the “Initial Period”), or, if longer as applicable pursuant to the terms of the Agreement, until the earlier of (A) 30 calendar days prior to the date of the Issuer’s 2014 annual shareholders’ meeting, and (B) 30 calendar days following the date on which Mr. Walsh (or his replacement) no longer remains a director serving on the Board of Directors. However, the Reporting Persons will be permitted, following expiration of the Initial Period and prior to the deadline for shareholders to submit director nominations for the Issuer’s 2014 annual shareholders’ meeting, to submit such nominations if Mr. Walsh (or his replacement) resigns from the Board of Directors prior to or contemporaneously with such submission and, in such event, the standstill period will terminate immediately.

Each of the Reporting Persons, on the one hand, and the Issuer, on the other hand, has agreed that, during the standstill period, it will not make disparaging or unfavorable remarks, comments or criticisms with regard to the other party, its business, or any of its current, future and former personnel, agents and representatives.

Each of the Reporting Persons has agreed to use its commercially reasonable efforts to cause its Shares to be present for quorum purposes and voted in support of Issuer-nominated directors at the 2013 annual shareholders’ meeting and at any other special shareholders’ meeting during the standstill period. The Issuer has agreed that the number of directors constituting the Board of Directors will be fixed at six during the standstill period.

The Issuer has agreed to reimburse the Reporting Persons for their reasonable out-of-pocket fees and expenses in connection with the Agreement and matters related to the 2013 annual shareholders’ meeting, up to a maximum of $25,000.

A copy of the Agreement is attached hereto as Exhibit 99.3. The foregoing description of the Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Agreement.

WHEREAS, the Nominating Committee has recommended that the Board nominate the PW Designee for election as a director of the Company at the Company’s 2013 annual shareholders’ meeting and any adjournments and postponements thereof (the “2013 Annual Meeting”) and the Board has determined that it is in the best interests of the Company to do so on the terms set forth in this Agreement;

The PW Designee shall serve as a director nominee in the place of incumbent director Christopher O’Donnell who shall not be re-nominated for election as a director by the Company and whose term as a director shall expire at the 2013 Annual Meeting. The Board will publicly recommend and solicit proxies for the election of the PW Designee at the 2013 Annual Meeting in the same manner as it does for all the other members of the Company Slate.

The Company has furnished to the PW Designee, prior to the execution of this Agreement, copies of all such policies, procedures, processes, codes, rules, standards and guidelines that are currently in effect.

(e) So long as the PW Group collectively beneficially owns, in the aggregate, at least 5.0% of the outstanding Common Stock, if, during the Initial Period (as defined below), a vacancy on the Board is created as a result of the PW Designee’s death, resignation, disqualification or removal, or the nomination of the PW Designee at the 2013 Annual Meeting is withdrawn for any reason, then the PW Group and the Company (acting through the Board) shall work together in good faith to fill such vacancy or replace such nominee with an individual who (i) meets the disclosure conditions set forth in clause (b) above, (ii) meets the historical standards and criteria applied by the Company in nominating and appointing directors, and (iii) is otherwise mutually acceptable (in each of their sole discretion) to the PW Group and the Company, and thereafter such individual shall serve and/or be nominated as the “PW Designee” under this Agreement.

(f) The Company’s obligations under this Section 1 shall terminate immediately, and the PW Designee shall promptly offer to resign from the Board (and, if requested by the Company, promptly deliver his written resignation to the Board (which shall provide for his immediate resignation) it being understood that it shall be in the Board’s sole discretion whether to accept or reject such resignation) if the members of the PW Group, collectively, cease to beneficially own at least 5.0% of the Company’s outstanding Common Stock. The PW Group agrees to cause the PW Designee to resign from the Board if the PW Designee fails to resign if and when requested pursuant to this clause (f).

(g) The percentage thresholds set forth in clauses (e) and (f) above shall not be deemed unsatisfied to the extent a failure to maintain the specified ownership thresholds is caused by share issuances or similar Company actions that increase the number of outstanding shares of Common Stock.

(h) The Company will use its commercially reasonable efforts to hold the 2013 Annual Meeting no later than May 7, 2013.

(i) During the Covered Period (as defined below), the number of directors constituting the Board will be fixed at six.

(j) If the PW Designee is elected at the 2013 Annual Meeting, (i) the Board will promptly appoint him to the Audit Committee and Strategic Planning Committee and will not remove him from serving as a member of each such committee during the Covered Period as long as the rules of the NASDAQ Stock Market and the Securities and Exchange Commission (“SEC”) and applicable provisions of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations promulgated thereunder would allow for such continued service on each such committee, (ii) the PW Designee will receive the same benefits of directors’ and officers’ insurance and any indemnity and exculpation arrangements available generally to the other Board members and the same compensation for his service as a director as the compensation received by the other Board members, and (iii) the PW Designee will comply with the same requirements as those generally applicable to the other Board members. Without limiting the generality of the foregoing, the PW Designee will not serve as a member of the Audit Committee to the extent he beneficially owns in excess of 10% of the shares of Common Stock outstanding.

Each member of the PW Group agrees that the Confidential Information will be kept confidential by the PW Designee and that the PW Designee will not disclose any of the Confidential Information in any manner whatsoever, including without limitation to other members of the PW Group, without the specific prior written consent of the Company unless disclosure is required by applicable laws or regulations or in connection with any judicial or regulatory proceedings (including by oral questions, interrogatories, requests for information or documents, subpoena, civil investigative demand or similar process); provided, however, that the term “Confidential Information” shall not include information that (a) was in or enters the public domain, or was or becomes generally available to the public, other than as a result of disclosure by the PW Designee in violation of this Agreement, or (b) was independently acquired or developed by the PW Designee without violating any of the obligations of the PW Designee or any other confidentiality agreement, or under any other contractual, legal, fiduciary or binding obligation of the PW Designee. Notwithstanding the foregoing, the PW Designee may disclose Confidential Information to his attorneys and, with the advance written permission of the Company, to his other Representatives, in each case who are instructed to keep such information confidential in accordance with the provisions of this Agreement and the PW Designee will be responsible for any failure by such Representatives to keep such information confidential. The PW Designee agrees to undertake reasonable precautions to safeguard and protect the confidentiality of the Confidential Information. Each member of the PW Group acknowledges that the U.S. securities laws prohibit any person who has received from an issuer material, non-public information concerning such issuer from purchasing or selling securities of such issuer or from communicating such information to any other person under circumstances in which it is reasonably foreseeable that such person is likely to purchase or sell such securities.

8. Release of Claims. On behalf of themselves and each of their respective directors, officers, managers, members and employees, the Company and each member of the PW Group hereby release and forever discharge each other, and each of their respective successors, assigns, parent and subsidiary companies, joint ventures, partnerships, owners, directors, officers, partners, principals, managers, members, employees, attorneys, consultants, financial advisors, shareholders, insurers and agents (collectively, “Released Persons”) from all claims and demands, rights and causes of action of any kind arising out of or relating to this Agreement and the election of directors at the 2013 Annual Meeting from the beginning of time through the date of this release. Notwithstanding anything to the contrary in this Section 8, the Company and each member of the PW Group do not release any obligations or claims related to the enforcement of the terms and provisions of this Agreement.

9. Miscellaneous. The parties agree that irreparable damage would occur in the event any of the provisions of this Agreement were not performed in accordance with the terms hereof and that such damage would not be adequately compensable in monetary damages. Accordingly, the parties hereto shall be entitled to an injunction or injunctions to prevent breaches of this Agreement, to enforce specifically the terms and provisions of this Agreement exclusively in the United States District Court for the District of Minnesota located in Hennepin County, or, if jurisdiction in such court is not available, the Hennepin County District Court in the State of Minnesota, in addition to any other remedies at law or in equity. Each of the parties hereto agrees to waive any bonding requirement under any applicable law, in the case any other party seeks to enforce the terms by way of equitable relief. Furthermore, each of the parties hereto

10. Expenses. Within five business days following receipt of reasonably satisfactory documentation thereof, the Company will reimburse the PW Group for its reasonable out-of-pocket fees and expenses incurred through the date of the execution and performance of this Agreement in connection with its activities relating to the 2013 Annual Meeting, including, without limitation, the nomination of Patrick Walsh, any acts or filings in connection therewith and the negotiation and execution of this Agreement in an amount not to exceed $25,000.

11. Entire Agreement; Amendment. This Agreement contains the entire agreement and understanding of the parties with respect to the subject matter hereof and supersedes any and all prior and contemporaneous agreements, memoranda, arrangements and understandings, both written and oral, between the parties, or any of them, with respect to the subject matter hereof. This Agreement may be amended only by an agreement in writing executed by the parties hereto, and no waiver of compliance with any provision or condition of this Agreement and no consent provided for in this Agreement shall be effective unless evidenced by a written instrument executed by the party against whom such waiver or consent is to be effective. No failure or delay by a party in exercising any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any right, power or privilege hereunder.

12. Notices. All notices, consents, requests, instructions, approvals and other communications provided for herein and all legal process in regard hereto shall be in writing and shall be deemed validly given, made or served when delivered in person or sent by overnight courier, when actually received during normal business hours at the address specified in this subsection:

13. Severability. If at any time subsequent to the date hereof, any provision of this Agreement shall be held by any court of competent jurisdiction to be illegal, void or unenforceable, such provision shall be of no force and effect, but the illegality or unenforceability of such provision shall have no effect upon the legality or enforceability of any other provision of this Agreement.

14. Counterparts. This Agreement may be executed in two or more counterparts either manually or by electronic or digital signature (including by facsimile or electronic mail transmission), each of which shall be deemed to be an original and all of which together shall constitute a single binding agreement on the parties, notwithstanding that not all parties are signatories to the same counterpart.

15. No Third Party Beneficiaries; Assignment. This Agreement is solely for the benefit of the parties hereto and is not binding upon or enforceable by any other persons. No party to this Agreement may assign its rights or delegate its obligations under this Agreement, whether by operation of law or otherwise, and any assignment in contravention hereof shall be null and void. Nothing in this Agreement, whether express or implied, is intended to or shall confer any rights, benefits or remedies under or by reason of this Agreement on any persons other than the parties hereto, nor is anything in this Agreement intended to relieve or discharge the obligation or liability of any third persons to any party.

16. Interpretation and Construction. When a reference is made in this Agreement to a Section, such reference shall be to a Section of this Agreement, unless otherwise indicated. The headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Whenever the words “include,” “includes” and “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The words “hereof, “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. The word “will” shall be construed to have the same meaning as the word “shall.” The words “dates hereof” will refer to the date of this Agreement. The word “or” is not exclusive.

Each of the parties hereto acknowledges that it has been represented by counsel of its choice throughout all negotiations that have preceded the execution of this Agreement, and that it has executed the same with the advice of said independent counsel. Each party cooperated and participated in the drafting and preparation of this Agreement and the documents referred to herein, and any and all drafts relating thereto exchanged among the parties shall be deemed the work product of all of the parties and may not be construed against any party by reason of its drafting or preparation. Accordingly, any rule of law or any legal decision that would require interpretation of any ambiguities in this Agreement against any party that drafted or prepared it is of no application and is hereby expressly waived by each of the parties hereto, and any controversy over interpretations of this Agreement shall be decided without regards to events of drafting or preparation.
