On November 10, 2011, the Board of Directors (the “Board”) of SigmaTron International, Inc. (the “Company”), adopted (a) the SigmaTron International, Inc. 2012 Employee Bonus Plan (the “Employee Plan”), a copy of which is attached hereto as Exhibit 10.1 and is incorporated herein by reference, and (b) the SigmaTron International, Inc. 2012 Officer Bonus Plan (the “Officer Plan” and, collectively with the Employee Plan, the “Plans”), a copy of which is attached hereto as Exhibit 10.2 and is incorporated herein by reference. The following is only a summary of the Plans, and in the event of any inconsistencies between the summary below and the Plans themselves, the Plans shall control. The stated purposes of the Plans are to align stockholder, employee and officer objectives, to motivate employees and officers of the Company and to increase shareholder value. Each of the Plans will be administered and interpreted by the Board. Each Plan, as a whole, is also subject to amendment, suspension or termination by the Board.

The Employee Plan.

The Employee Plan applies to all U.S. payroll non-union employees of the Company (“Employee Participants”), all full-time employees of the Company with a corporate position of vice president or higher (“Officers”) and all employees designated by the Company as an executive officer pursuant to the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (“Executive Officers”).

Pursuant to the Employee Plan, a Bonus Pool shall be created under the Employee Plan shall be calculated as a percentage of Pre-Tax Income (as defined in the Employee Plan) pursuant to the scale set forth in the Employee Plan. The Company’s Chief Executive Officer will submit to the Company’s Compensation Committee a recommendation (i) of target objectives for each Executive Officer and (ii) for a specified percentage or dollar allocation of the Bonus Pool for each Executive Officer and Officer, individually, and all of the Employee Participants, in the aggregate. The Compensation Committee will review such submissions for recommendation to the Board. Awards to Executive Officers under the Employee Plan will be based, in part, on the Executive Officer achieving the Executive Officer’s specified target objectives and, in any event, will be subject to the sole discretion of the Board. Awards to Employee Participants under the Employee Plan will be contingent upon the Company being in compliance with all of the Company’s covenants under its primary credit facility (currently with Wells Fargo Bank, N.A.), or having obtained a waiver thereof, at the end of the Company’s 2012 fiscal year.

The Officer Plan.

The Officer Plan applies to all full-time employees of the Company with a corporate position of vice president or higher (“Participants”), and establishes the terms and conditions upon which the Company intends to pay cash bonuses in the aggregate totaling $170,000 (the “Officer Plan Bonus Pool”) to eligible Participants for the Company’s 2012 fiscal year. Bonuses under the Officer Plan will be paid only if (1) the Company’s Pre-Tax Income (as defined in the Officer Plan) for the 2012 fiscal year equals or exceeds $340,000, (2) the Company is in compliance with all of the covenants under the Company’s primary credit facility (currently with Wells Fargo Bank, N.A.), or has obtained a waiver thereof, at the end of the Company’s 2012 fiscal

year and (3) the Company has achieved the Operational Objectives (as defined in the Officer Plan) approved by the Board of Directors. The Company’s Chief Executive Officer is responsible for submitting a proposed allocation of the Officer Plan Bonus Pool amongst the eligible Participants to the Committee, which shall review such proposal and is responsible for making a Bonus Pool allocation recommendation to the Board.
