National Technical Systems Adopts Shareholder Rights Plan

Calabasas, CA (September 22, 2010)…National Technical Systems, Inc. (the "Company") (Nasdaq: NTSC) announced today that its Board of Directors (the "Board") has approved the adoption of a Shareholder Rights Plan (the “Rights Plan”) under which shareholders will receive rights to purchase shares of a new series of preferred stock of the Company in certain circumstances.

The Board adopted the Rights Plan in response to the filing of a Schedule 13D with the Securities and Exchange Commission by certain shareholders of the Company, including Jack Lin, a director of the Company, in which they disclosed, among other things, that they have engaged a financial advisor in connection with the potential sale of their shares of common stock of the Company, which they disclosed may involve a change in the financial structure, control or ownership of all or a portion of the company. The Rights Plan is intended to protect the Company and its shareholders from efforts to obtain control of the Company that are inconsistent with the best interests of the Company and its shareholders.

The rights will be exercisable ten days following the earlier of the public announcement that a shareholder has acquired 15% or more of the Company's common stock without Board approval and the announcement of a tender offer which results in the ownership of 15% or more of the Company's common stock.  The rights also will become exercisable if a person or group that already owns 15% or more of the Company's common stock, without Board approval, acquires any additional shares (other than pursuant to the Company's employee benefit plans). If the rights become exercisable, all rights holders (other than the person triggering the rights) will be entitled to acquire Company securities at a 50% discount.

Donald J. Tringali, the Company’s Chairman of the Board, commented, “We are implementing this Rights Plan to ensure that, should the Company receive an unsolicited offer, our directors will have adequate time to evaluate any such offer carefully and diligently.  Exclusive of Jack Lin, board members with holdings representing approximately18 percent of outstanding shares voted unanimously to put this plan in place, and are focused on continuing to deliver value to our shareholders and quality services to our customers. We will review this Rights Plan annually.”

The rights will trade with the Company's common stock, unless and until they are separated upon the occurrence of certain future events.  The rights expire September 20, 2020, unless redeemed for $0.001 per right or exchanged earlier by the Board.  The Board may terminate the Rights Plan prior to the time the rights are triggered. Further details of the Rights Plan will be contained in a Form 8-K to be filed with the Securities and Exchange Commission.
