Exhibit 10.1

EXECUTION COPY

AGREEMENT

This AGREEMENT (this “Agreement”) is entered into as of this 27^th day of January, 2012, by and among Red Oak Partners, LLC, a New York limited liability company, and the persons and entities affiliated with it and listed on the signature page hereof (“Red Oak”), and Planar Systems, Inc., an Oregon corporation (the “Company”).

WHEREAS, the Company has been discussing with David Sandberg, an affiliate of Red Oak, a shareholder of the Company, the merits of making certain corporate governance changes to more closely align the Company’s posture with current best practices as supported by a growing number of shareholder advocacy organizations;

WHEREAS, the Company is undertaking actions to obtain shareholder approval to remove the staggered director term structure presently in place, a change that the Company and Mr. Sandberg agree is in the best interests of the Company and its shareholders;

WHEREAS, the Company’s board of directors (the “Board”) invited Mr. Sandberg to consider serving as one of the Company’s nominees for election to the Board at the Company’s 2012 Annual Meeting of Shareholders (“2012 Annual Meeting”), and he agreed to do so; and

WHEREAS, the Company and Mr. Sandberg and his affiliates desire to memorialize their agreements relating to eliminating the staggered director term structure of the Board and Mr. Sandberg’s nomination for election to the Board.

NOW, THEREFORE, in consideration of the foregoing, the parties hereto agree as follows:

1. Director Nominees. The Company and Red Oak agree that the nominees for director to be proposed by the Board for election at the 2012 Annual Meeting shall be Gerald K. Perkel and David Sandberg, each for a three-year term. The Company’s Proxy Statement will recommend election of both the nominees.

2. Number of Directors. There shall be no restrictions on the number of directors authorized by the Board in accordance with the Bylaws of the Company. The parties understand that Oregon law provides that the term of any director elected by the Board to fill a vacancy on the Board expires at the next meeting of shareholders at which directors are elected. The Company acknowledges the merits of reasonable periodic rotation of Board membership.

3. Board Committees.

(a) David Sandberg, if elected, shall be appointed to serve on the Compensation Committee and the Governance Committee, with such appointments to extend at least until the day after the 2013 Annual Meeting. Mr. Sandberg shall be permitted to serve on not less than two committees, and shall be permitted to serve on the same number of committees as the director serving on the most committees of the Board, provided that he is eligible to serve on each such committee.

1

(b) In order to provide an opportunity for Mr. Sandberg, prospectively a newly appointed member of the Compensation Committee, to better understand the Company’s equity incentive programs and to share his thoughts about such incentive programs, the Company agrees that, prior to the first meeting of the Compensation Committee after the appointment of David Sandberg to the Committee, no additional equity awards will be granted to the Company’s directors or its three executive officers.

(c) The Company hereby represents that the Board has not appointed an Executive Committee or other committee with similar Board authority, and hereby agrees that from the date of this Agreement until the day after the 2013 Annual Meeting, no such committee shall be appointed, except by unanimous approval of all members of the Board.

4. Amendment to Articles of Incorporation. The Board will adopt and recommend to the shareholders of the Company for approval at the 2012 Annual Meeting an amendment to Article VI of the Company’s Second Amended and Restated Articles of Incorporation (the “Articles of Incorporation”) in substantially the form of the draft provided to Red Oak on January 23, 2012 (the “Articles Amendment”).

5. Voting Agreement and Solicitation.

(a) Red Oak agrees that it will cause all shares of voting stock beneficially owned by it and its affiliates to be present for quorum purposes and to be voted at the 2012 Annual Meeting (i) in favor of each of those individuals nominated as directors as set forth in Section 1 above, (ii) in favor of approval of the Articles Amendment, (iii) in favor of approval of the ratification of the appointment of the Company’s independent registered public accounting firm, and (iv) in favor of each other proposal consistent with the terms hereof contained in the Proxy Statement in the manner that the Board recommends in the Proxy Statement (the “Proposals”).

(b) The Company’s proxy statement for the 2012 Annual Meeting (the “Proxy Statement”) shall include the Board’s recommendation for approval of the Proposals. The Company shall permit Mr. Sandberg to review the Company’s Proxy Statement before it is mailed to shareholders and shall reasonably consider any changes requested by Mr. Sandberg. The Company shall retain The Proxy Advisory Group, LLC to assist in the Board’s solicitation of proxies for approval of the Proposals, and shall use its best efforts to obtain approval of the Proposals.

(c) Mr. Sandberg agrees that if the Articles Amendment is adopted at the Company’s 2012 Annual meeting, he will, to the extent necessary to implement such Articles Amendment, resign from the Company’s board of directors on the date of the 2013 Annual Meeting, subject to the right of the Company to nominate, and its shareholders to elect, him for a one-year term commencing on the date of the 2013 Annual Meeting.

No delay or omission on the part of any party in exercising any right, power or remedy under this Agreement shall operate as a waiver thereof.

This Agreement shall become effective when duly executed by each party hereto.

16. Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. In the event that any provision hereof would, under applicable law, be invalid or unenforceable in any respect, each party hereto intends that such provision shall be construed by modifying or limiting it so as to be valid and enforceable to the maximum extent compatible with, and possible under, applicable law.

17. Governing Law. This Agreement, the rights of the parties and all actions arising in whole or in part under or in connection herewith, shall be governed by and construed in all respects, including validity, interpretation and effect, in accordance with the laws of Oregon, applicable to contracts executed and to be performed wholly within such state without giving

6

effect to any choice or conflict of law provision or rule that would cause the application of the laws of any other jurisdiction. Each of the parties hereto (a) consents to submit itself to the personal jurisdiction of the state and federal courts in Oregon in the event any dispute arises out of this Agreement or the transactions contemplated by this Agreement, (b) agrees that it shall not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court, (c) agrees that it shall not bring any action relating to this Agreement or the transactions contemplated by this Agreement in any court other than the state or federal courts in Oregon, (d) 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 and (e) each of the parties irrevocably consents to service of process by first class certified mail, return receipt requested, postage prepaid, to the address of such parties’ principal place of business or as otherwise provided by applicable law.

18. Construction. Each party cooperated and participated in the drafting and preparation of this Agreement and the documents referred to herein. 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 regard to events of drafting or preparation.
