Item 4.

Purpose of Transaction.

Item 4 of the Initial Statement is hereby replaced in its entirety with the following:

The Reporting Persons have acquired the Common Stock reported herein for investment purposes. Consistent with such purpose, the Reporting Persons have had, and may have in the future, discussions with management of the Company and may make suggestions concerning the Company’s operations, prospects, business and financial strategies, assets and liabilities, business and financing alternatives and such other matters as the Reporting Persons may deem relevant to their investments in the Common Stock and other securities of the Company. Each Reporting Person expects that he or it will, from time to time, review his or its investment position in the Company and may, depending on market or other conditions, increase or decrease his or its investment position in the Common Stock or other securities of the Company.

Whether the Reporting Persons purchase any additional Common Stock or other securities of the Company or dispose of any Common Stock or other securities of the Company, and the amount and timing of any such transactions, will depend upon the Reporting Persons’ individual continuing assessments of relevant factors, including the availability of Common Stock or other securities of the Company for purchase at particular price levels, the Company’s and the particular Reporting Person’s business and prospects, other business opportunities available to the particular Reporting Person, economic conditions, stock market conditions, money market conditions, the attitudes and actions of the board of directors and management of the Company, the availability and nature of opportunities to dispose of the particular Reporting Person’s interest in the Company, to realize trading profits or minimize trading losses, and other plans and requirements of the particular Reporting Person. Depending upon individual assessments of these factors from time to time, each Reporting Person may change the present intentions as stated above, including determining to purchase additional Common Stock or other securities of the Company (by means of open market or privately negotiated purchases) or to dispose of some or all of the Common Stock or other securities of the Company held by or under the control of such Reporting Person. In addition, each Reporting Person may from time to time enter into equity swap and other derivative transactions with respect to his or its investment in Common Stock or other securities of the Company.

Mr. Hernandez is a significant shareholder of the Company. In the past, Mr. Hernandez has proposed, both at the Company’s annual meeting of shareholders and in correspondence directed to the board of directors, that the Company conduct a sales process.

Dr. Lin is a member of the board of directors of the Company. As a director and a significant shareholder, Dr. Lin regularly interacts with management and the other directors to discuss operational, strategic and business issues affecting the Company. In the past, Dr. Lin has proposed that the Company conduct a sales process and has proposed that the Company purchase his shares of Common Stock. Dr. Lin intends to implement a 10b5-1 trading plan to dispose of shares of Common Stock on terms that have not yet been determined.

On September 8, 2010, the Reporting Persons entered into a financial advisory engagement letter (the “Engagement Letter”) with M&A Capital, LLC (“M&A Capital”), pursuant to which the Reporting Persons retained M&A Capital as their exclusive financial advisor in connection with any potential direct or indirect sale, exchange or other disposition of all or a portion of the Reporting Persons’ shares of Common Stock, whether accomplished by a sale of assets, securities or other interests, and whether effected in one transaction or multiple transactions, and including, without limitation, any negotiated purchase, merger or consolidation, reorganization, recapitalization or restructuring, tender or exchange offer, joint venture, partnership, equity or debt investment, or any other transaction that results in a change in the financial structure, control or ownership of all or a portion of the Company (a “Sale Transaction”). The Engagement Letter had a three-month term and, thereafter, has continued until such time as it is terminated by either M&A Capital or the Reporting Persons upon 30 days’ prior written notice.

On April 6, 2011, the Reporting Persons notified the Company that the Reporting Persons were exercising their rights to nominate three directors as Class III Directors for election by the shareholders of the Company at the 2011 annual meeting of the shareholders of the Company. The Reporting Persons nominated the following individuals:

Jack Lin, Ph.D. founded the Company and served as its Chief Executive Officer until May 2005. Dr. Lin served as Chairman of the Company until May 2010. He has been Chairman Emeritus of NTS since May 2010. Dr. Lin has been Director of the Company since 1975.

Harry S. Derbyshire is a business consultant who served as executive vice president and chief financial officer of Whittaker Corp. prior to his retirement in July 1985. Mr. Derbyshire has previously served on the board of National Technical Systems and Western Waste Industries.

Jeff Kaplan was President and Founder of Giant Merchandising, a $170 million in revenue worldwide entertainment based merchandising company. The Company was sold to Time Warner-Warner Music Group in 1995, with Mr. Kaplan staying on as President until 2005.

These nominees are aligned with the Reporting Persons’ desire to explore a Sale Transaction.

On April 6, 2011, the Reporting Persons also notified the Company that the Reporting Persons were exercising their rights to submit a proposal to amend the Bylaws of the Company (the “Bylaws”) for consideration at the 2011 annual meeting of the shareholders of the Company. The Reporting Persons propose to amend the first sentence of Section 3.2 of the Bylaws to eliminate the range of directors (currently from 9 to 17) and fix the number of authorized directors at 9. In addition, the Reporting Persons propose to amend Section 9.2 of the Bylaws to provide that if the first sentence of Section 3.2 is so amended and approved by the shareholders as provided in the preceding sentence, the first sentence of Section 3.2, as amended, and the related portion of Section 9.2 may be amended further or repealed only by approval of the outstanding shares and not by the directors.

Except as set forth in this Item 4, the Reporting Persons have no present plans or proposals that relate to or that would result in any of the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D of the Act.

Item 5.

Interest in Securities of the Issuer.

(a)-(b) The responses to Items 7-13 of the cover pages of this Statement are incorporated herein by reference.

(d) To the knowledge of the Reporting Person, no other person is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of the Common Stock.

(e) Not applicable.

Item 6.

Contracts, Arrangements, Undertakings or Relationships with Respect to Securities of the Issuer.

Except as set forth herein, there are no contracts, arrangements, understandings or relationships of the type required to be disclosed in response to Item 6 of Schedule 13D of the Act with respect to the Common Stock owned by the Reporting Persons.
