PRELIMINARY PROXY STATEMENT—SUBJECT TO COMPLETION, DATED SEPTEMBER 16, 2013

NATIONAL TECHNICAL SYSTEMS, INC.

24007 VENTURA BOULEVARD

CALABASAS, CALIFORNIA 91302

You are cordially invited to attend a special meeting of the shareholders of National Technical Systems, Inc., a California corporation (“NTS,” the “Company,” “we,” “our” or “us”), which we will hold on [    ], 2013, at [    ], at [    ], local time.

On August 15, 2013, the Company entered into an Agreement and Plan of Merger (the “merger agreement”) providing for the acquisition of the Company by Nest Parent, Inc. (“Parent”). Pursuant to the merger agreement, Nest Merger Sub, Inc., a California corporation and a wholly-owned subsidiary of Parent (“Merger Sub”), will merge with and into NTS, with NTS surviving the merger as a wholly-owned subsidiary of Parent (the “merger”). Following the merger, NTS will cease to be a publicly traded company. Parent and Merger Sub are affiliates of Aurora Capital Group.

At the special meeting, you will be asked to consider and vote upon the following: (i) a proposal to approve the merger agreement and the transactions contemplated thereby, including the merger (which we refer to as the “merger agreement proposal”); (ii) an advisory (non-binding) proposal to approve specified compensation that may become payable to the named executive officers of NTS in connection with the merger; and (iii) a proposal to approve the adjournment of the special meeting to solicit additional proxies, if necessary or appropriate, if there are insufficient votes at the time of the special meeting to approve the merger agreement proposal.

If the merger is completed, each share of NTS common stock issued and outstanding immediately prior to the effective time of the merger (other than shares owned by NTS, Parent and Merger Sub and any of their respective direct and indirect subsidiaries and by holders who are entitled to and properly exercise dissenters’ rights under California law) will be cancelled and converted into the right to receive $23.00 in cash (the “per share merger consideration”), without interest and less applicable withholding taxes. The per share merger consideration represents a premium of approximately 39% to NTS’s closing stock price on August 15, 2013, the last full trading day before the public announcement of the merger.

The NTS board of directors formed a special committee of three disinterested and independent directors to, among other things, review and evaluate the merger agreement proposal. The NTS board of directors has unanimously, and in accordance with the unanimous recommendation of the special committee, approved the merger agreement and determined that the merger agreement and the transactions contemplated thereby are advisable, fair to and in the best interests of NTS and its shareholders. The NTS board of directors unanimously recommends that NTS shareholders vote “FOR” the merger agreement proposal. Additionally, the NTS board of directors unanimously recommends that NTS shareholders vote “FOR” the advisory (non-binding) proposal to approve specified compensation that may become payable to the named executive officers of NTS in connection with the merger, and “FOR” the proposal to adjourn the special meeting to solicit additional proxies, if necessary or appropriate, if there are insufficient votes at the time of the special meeting to approve the merger agreement proposal.

In considering the recommendation of the NTS board of directors, you should be aware that some of NTS’s directors and executive officers have interests in the merger that are different from, or in addition to, shareholders generally.

The enclosed proxy statement describes the merger agreement, the merger and related agreements and provides specific information concerning the special meeting. In addition, you may obtain information about us from documents filed with the Securities and Exchange Commission (the “SEC”). You should read the entire proxy statement carefully, including the appendices, because it sets forth the details of the merger agreement and other important information related to the merger.

In connection with the entry into the merger agreement, on August 15, 2013, all of our executive officers and directors (other than Mr. Justin C. Jacobs), representing approximately 18% of our outstanding common stock as of the date thereof, entered into a voting agreement with Parent, agreeing to, among other things, vote all shares of our common stock owned of record and beneficially by such officers and directors in favor of the merger, the merger agreement and any other matters relating to and/or necessary for consummation of the merger and the other transactions contemplated in the merger agreement.

Your vote is very important. NTS cannot complete the merger unless the merger agreement proposal is approved by the affirmative vote of the holders of a majority of the outstanding shares of NTS common stock entitled to vote at the special meeting. The advisory (non-binding) proposal to approve specified compensation that may become payable to the named executive officers of NTS in connection with the merger, is subject to a separate shareholder vote, and approval of that proposal is not a condition to the completion of the merger. If you fail to vote on the merger agreement proposal, the effect will be the same as a vote “AGAINST” this proposal. Whether or not you plan to attend the special meeting, please complete, sign, date and return the enclosed proxy card or submit your proxy by telephone or on the Internet as soon as possible. If you hold your shares in “street name,” you should instruct your broker, bank or other nominee how to vote in accordance with your voting instruction card. If you do not submit your proxy, instruct your broker, bank or other nominee how to vote your shares, or vote in person at the special meeting, it will have the same effect as a vote “AGAINST” the merger agreement proposal.

If you have any questions or need assistance in voting your shares, please contact our proxy solicitor, [    ], by calling [    ] (toll free).

On behalf of the NTS board of directors, I thank you for your support and appreciate your consideration of this matter.

Sincerely,

William McGinnis

Chief Executive Officer and President

Neither the Securities and Exchange Commission nor any state securities regulatory agency has approved or disapproved the merger, passed upon the merits or fairness of the merger or passed upon the adequacy or accuracy of the disclosure in this document. Any representation to the contrary is a criminal offense.

This proxy statement and the form of the proxy are first being sent to NTS shareholders on or about [    ], 2013.

If you do not submit your proxy, instruct your broker, bank or other nominee how to vote your shares, or vote in person at the special meeting, it will have the same effect as a vote “AGAINST” the merger agreement proposal.

SUMMARY

This Summary highlights selected information contained in this proxy statement. You should carefully read this entire proxy statement, its annexes and the documents referred to or incorporated by reference in this proxy statement (see “Where You Can Find Additional Information” on page 88), as this Summary may not contain all of the information that may be important to you in considering the proposed merger. The items in this Summary include page references directing you to a more complete description of that topic in this proxy statement.

Parties to the Merger (Page 26)

National Technical Systems, Inc. National Technical Systems, Inc., referred to as “NTS,” the “Company,” “we,” “our” or “us,” is a California corporation. NTS is a leading independent provider of testing, inspection and certification services in the United States, serving a number of end markets. NTS’s corporate headquarters are located in Calabasas, California. See “Parties to the Merger — National Technical Systems, Inc.” on page 26. Additional information about NTS is contained in its public filings, which are incorporated by reference in this proxy statement. See “Where You Can Find Additional Information” on page 88.

Nest Parent, Inc. Nest Parent, Inc., referred to as “Parent,” is a Delaware corporation. Parent was formed in connection with the transactions contemplated by the merger agreement. Parent has not engaged in any business except in furtherance of this purpose. Parent is an affiliate of Aurora Capital Group, a Los Angeles-based private equity firm. See “Parties to the Merger — Nest Parent, Inc.” on page 26.

Nest Merger Sub, Inc. Nest Merger Sub, Inc., referred to as “Merger Sub,” is a California corporation and a wholly-owned subsidiary of Parent that was formed in connection with the transactions contemplated by the merger agreement. Upon the consummation of the merger, Merger Sub will be merged with and into NTS and will cease to exist. See “Parties to the Merger — Nest Merger Sub, Inc.” on page 26.

The Merger (Page 27)

Parent and NTS agreed to the acquisition of NTS by Parent under the terms of the merger agreement that is described in this proxy statement. Pursuant to the merger agreement, Merger Sub will merge with and into NTS, with NTS surviving the merger and continuing as a wholly-owned subsidiary of Parent. The merger agreement is attached as Annex A to this proxy statement. We encourage you to read carefully the merger agreement in its entirety because it is the legal document governing the merger.

Merger Consideration (Page 28)

If the merger is completed, you will receive $23.00 in cash, without interest and less applicable withholding taxes, for each share of NTS common stock that you owned immediately prior to the effective time and for which you did not properly exercise dissenters’ rights. After the merger is completed, you will have the right to receive the per share merger consideration, but you will no longer have any rights as a NTS shareholder. NTS shareholders will receive the per share merger consideration after exchanging their NTS stock certificates in accordance with the instructions contained in the letter of transmittal to be sent to all NTS shareholders promptly after the effective time of the merger. See “The Merger Agreement — Payment Procedures” on page 66.

Treatment of Equity Awards and Treatment of Warrants (Page 67)

Pursuant to the merger agreement, at the effective time of the merger, and as a result of the merger:

• each option to acquire NTS common stock (whether vested or unvested) that is outstanding at the effective time of the merger will become vested in full and will be cancelled in exchange for the right to receive (subject to any applicable withholding taxes) the per share merger consideration minus the

1

exercise price per share of the option; provided that if the exercise price per share of an option is equal to or greater than the per share merger consideration, then the option will be cancelled without any cash payment being made in respect of such option;

• each restricted share of NTS common stock (whether vested or unvested) that is outstanding at the effective time of the merger will vest in full and will be cancelled and convert into solely the right to receive (subject to any applicable withholding taxes) the per share merger consideration; and

• each warrant to purchase NTS common stock that is outstanding at the effective time of the merger will be cancelled in exchange for the right to receive the per share merger consideration minus the exercise price per share of the warrant; provided that if the exercise price per share of a warrant is equal to or greater than the per share merger consideration, then the warrant will be cancelled without any cash payment being made in respect of such warrant.

In addition, pursuant to NTS’s 2010 Long-Term Incentive Plan (the “LTIP”), each vested phantom stock appreciation right will be cancelled in the merger in exchange for the right to receive an amount in cash (subject to any applicable withholding taxes) equal to the product of the excess of the per share merger consideration over the applicable grant price per phantom stock appreciation right. On October 23, 2012, the compensation committee of the NTS board of directors exercised its discretion to accelerate the vesting of all phantom stock appreciation rights in connection with a change of control occurring before October 23, 2014. Accordingly, all outstanding and unvested phantom stock appreciation rights are expected to vest in the merger and be cancelled in exchange for the aforementioned consideration.

Market Prices and Dividend Data (Page 20)

NTS common stock is quoted on the NASDAQ Global Market under the symbol “NTSC.” On August 15, 2013, the last full trading day before the public announcement of the merger, the closing price for our common stock was $16.58 per share and on [    ], 2013, the latest practicable trading day before the printing of this proxy statement, the closing price for our common stock was $[    ] per share.

Material U.S. Federal Income Tax Consequences of the Merger (Page 49)

U.S. Holders (as defined on page 49) of NTS common stock that exchange all of their shares of NTS common stock for cash (pursuant to the merger agreement) will recognize gain or loss on the exchange in an amount equal to difference between the amount of the cash received and that holder’s adjusted tax basis in the shares of NTS common stock exchanged therefor. Shareholders, including non-U.S. Holders (as defined on page 50) should consult their own tax advisors concerning the U.S. federal income tax consequences relating to the merger in light of their particular circumstances and any consequences arising under the laws of any state, local or foreign taxing jurisdiction.

Reasons for the Merger and Recommendation of the NTS Board of Directors (Pages 36 and 38)

The NTS board of directors consulted with management, the NTS special committee and the special committee’s legal and financial advisors in connection with its evaluation of the merger agreement and the merger. After careful consideration of the various factors described in the section entitled “The Merger — Reasons for the Merger,” at a special meeting of the NTS board of directors on August 15, 2013, upon the unanimous recommendation of the NTS special committee, the NTS board of directors unanimously (i) determined that the terms of the merger agreement, the merger and the other transactions contemplated thereby are fair to and in the best interests of NTS shareholders, (ii) approved and declared advisable the merger agreement and the transactions contemplated thereby, including the merger, (iii) directed that the merger agreement be submitted to the shareholders of NTS for adoption and approval and (iv) recommended that NTS’s shareholders vote in favor of the adoption and approval of the merger agreement and the transactions contemplated thereby, including the merger.

2

In considering the recommendation of the NTS board of directors, you should be aware that some of NTS’s directors and executive officers have interests in the merger that are different from, or in addition to, shareholders generally. See “The Merger — Interests of NTS Executive Officers and Directors in the Merger” beginning on page 52.

The NTS board of directors unanimously recommends that you vote “FOR” the merger agreement proposal; “FOR” the advisory (non-binding) proposal to approve specified compensation that may become payable to the named executive officers of NTS in connection with the merger; and “FOR” the proposal to adjourn the special meeting to solicit additional proxies, if necessary or appropriate, if there are insufficient votes at the time of the special meeting to approve the merger agreement proposal.

Opinion of Financial Advisor to the NTS Special Committee (Page 39)

On August 15, 2013, the NTS special committee’s financial advisor, Houlihan Lokey Capital, Inc., or “Houlihan Lokey,” rendered an oral opinion to the NTS special committee (which was confirmed in writing by delivery of Houlihan Lokey’s written opinion dated August 15, 2013), as to, as of August 15, 2013, the fairness, from a financial point of view, of the $23.00 per share consideration to be received by the holders of NTS common stock in the merger pursuant to the merger agreement.

Houlihan Lokey’s opinion was directed to the NTS special committee and only addressed the fairness from a financial point of view of the $23.00 per share consideration to be received by the holders of NTS common stock in the merger pursuant to the merger agreement and does not address any other aspect or implication of the merger. The summary of Houlihan Lokey’s opinion in this proxy statement is qualified in its entirety by reference to the full text of its written opinion, which is attached as Annex B to this proxy statement and sets forth the procedures followed, assumptions made, qualifications and limitations on the review undertaken and other matters considered by Houlihan Lokey in preparing its opinion. NTS encourages its shareholders to carefully read the full text of Houlihan Lokey’s written opinion. However, neither Houlihan Lokey’s opinion nor the summary of its opinion and the related analyses set forth in this proxy statement are intended to be, and do not constitute, advice or a recommendation to the special committee, the board of directors, NTS or any shareholder as to how to act or vote with respect to the merger or related matters. See “The Merger — Opinion of Financial Advisor to the NTS Special Committee” on page 39.

Financing of the Merger (Page 47)

Parent has received an equity commitment letter, dated August 15, 2013, from Aurora Pacific Equity Partners, Inc., pursuant to which Aurora Pacific Equity Partners, Inc. has committed to make, or cause its affiliates to make, an equity contribution of $177.0 million to Parent. Parent has also received a debt commitment letter, dated August 15, 2013, from GCI Capital Markets LLC, referred to as “Golub,” pursuant to which Golub has committed to provide $152.5 million of first lien senior secured credit facilities and $55.0 million of second lien senior secured credit facilities. We refer to the equity and debt commitment letters as the “financing commitments.” We believe the aggregate proceeds to be distributed pursuant to the financing commitments, together with cash and cash equivalents available to Parent, will, in the aggregate, be sufficient for Parent to:

• consummate the merger;

• pay the merger consideration to NTS shareholders and to the holders of NTS options, warrants and phantom stock appreciation rights;

• repay at the closing of the merger certain indebtedness of NTS and its subsidiaries;

• pay certain fees, costs and expenses associated with closing the merger and the credit facilities; and

• provide for working capital, capital expenditures and other corporate purposes following the merger.

3

Although consummation of the merger is not subject to a financing condition, the funding under the financing commitments is subject to conditions, including conditions that do not relate directly to the conditions to closing in the merger agreement. See “The Merger — Financing of the Merger” on page 47.

In addition, pursuant to the merger agreement, as an alternative to the credit facilities provided for in the debt commitment letter, Parent and Merger Sub may obtain substitute financing in the form of a single lien senior secured credit facility so long as the replacement of the credit facilities with the substitute financing would not be adverse in any material respect to NTS, taking the credit facilities and substitute financing as a whole. Parent and Merger Sub currently intend to utilize such substitute financing, and expect it to be in the form of a $183.0 million senior secured credit facility, comprised of a (i) $143.0 million term loan, advanced in full on the closing date, (ii) a $30.0 million delayed draw term loan, and (iii) a $10.0 million revolving loan facility.

Special Meeting of Shareholders; Voting by NTS Executive Officers and Directors (Pages 22 and 24)

Date, Time and Place. The special meeting of NTS shareholders will be held on [    ], 2013, at [    ], at [    ] local time to:

• consider and vote upon the merger agreement proposal;

• consider and vote, on an advisory (non-binding) basis, upon specified compensation that may become payable to the named executive officers of NTS in connection with the merger;

• consider and vote upon a proposal to adjourn the special meeting to a later date, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the merger agreement proposal; and

• transact such other business as may properly come before the special meeting or any adjournment of the special meeting.

Record Date and Voting Power. You are entitled to vote at the special meeting if you held shares of NTS common stock at the close of business on September 20, 2013, the record date for the special meeting. You will have one vote at the special meeting for each share of NTS common stock you owned at the close of business on the record date. [    ] shares of NTS common stock are entitled to be voted at the special meeting.

Vote Required. In order to approve the merger agreement proposal, holders of at least a majority of the outstanding shares of NTS common stock entitled to vote at the special meeting must vote in favor of this proposal. Approval, on a non-binding advisory basis, of specified compensation that may become payable to the named executive officers of NTS in connection with the merger requires the affirmative vote of a majority of the shares represented and voting at the special meeting (which shares voting affirmatively also constitute at least a majority of the required quorum). Approval of the proposal to adjourn the special meeting to a later date, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the merger agreement proposal requires approval of a majority of the shares represented at the special meeting, either in person or by proxy, whether or not a quorum is present.

Voting Agreement. Each NTS executive officer and director other than Mr. Justin C. Jacobs (collectively, the “covered directors and officers”) has entered into a voting agreement with Parent (the “voting agreement”) with respect to all shares of NTS common stock owned of record and beneficially by the covered directors and officers, as set forth in the voting agreement, and any additional shares of common stock and any other voting securities of NTS which the covered directors and officers acquire record and/or beneficial ownership of after the date of the voting agreement (collectively, the “voting agreement shares”). The covered directors and officers collectively own approximately 18% of the outstanding shares of NTS common stock and have agreed to take the following actions, among others, during the term of the voting agreement: (1) vote all voting agreement shares in favor of the merger, the merger agreement and any other matters relating to and/or necessary for consummation of the merger and the other transactions contemplated in the merger agreement; (2) vote all voting agreement

4

shares against any “acquisition proposal” as defined below on page 74; (3) vote all voting agreement shares against any other actions that would or could reasonably be expected to adversely affect or delay the merger; and (4) vote all voting agreement shares in favor of any proposal to adjourn the special meeting to a later date if a quorum is not present or if there are not sufficient votes for the adoption of the merger agreement. In addition, each covered director and officer has granted to Parent (and its executive officers and designees), pursuant to the voting agreement, an irrevocable proxy to vote the voting agreement shares in accordance with the foregoing.

Interests of NTS Executive Officers and Directors in the Merger (Page 52)

When considering the recommendation of the NTS board of directors that NTS shareholders vote in favor of the merger agreement proposal, you should be aware that NTS executive officers and directors have interests in the merger that are different from, or in addition to, the interests of NTS’s shareholders generally. See “The Merger — Interests of NTS Executive Officers and Directors in the Merger” for a description of such interests that may be different from, or in addition to, the interests of NTS shareholders generally.

The NTS board of directors knew about these interests and considered them, among other matters, when it determined that the merger agreement and the merger are fair to, advisable and in the best interests of NTS and its shareholders.

The following is a summary of certain interests of NTS executive officers and directors in the merger:

• Positions with Surviving Corporation. Following the consummation of the merger, it is expected that the members of NTS’s senior management will hold substantially similar positions with NTS, as the surviving corporation in the merger. It is anticipated that following the merger, NTS’s executive officers will enter into employment agreements with NTS.

• Stock Ownership. Certain NTS executive officers and directors beneficially own shares of NTS common stock. At the effective time of the merger, all shares of NTS common stock, including shares of restricted stock, held by NTS’s executive officers and directors will be cancelled in exchange for a right to receive an amount in cash (subject to any applicable withholding taxes) equal to the per share merger consideration of $23.00 per share.

• Stock Options. Certain NTS executive officers and directors hold stock options granted pursuant to NTS’s 2002 Stock Option Plan, which was subsequently replaced by the 2006 Equity Incentive Plan. Each stock option that is outstanding and unexercised as of immediately prior to the effective time of the merger will be cancelled in the merger in exchange for the right to receive an amount in cash (without interest and subject to any applicable withholding taxes) equal to the product of (1) the excess, if any, of the per share merger consideration over the applicable exercise price per share of such stock option, and (2) the aggregate number of shares of common stock issuable upon exercise of such stock option. Each stock option that is currently outstanding, including those held by NTS directors and executive officers, has a per share exercise price below the per share merger consideration of $23.00 per share.

• Restricted Stock. Certain NTS directors hold shares of restricted stock subject to stock awards granted pursuant to NTS’s 2006 Equity Incentive Plan. Pursuant to the terms of the merger agreement, each share of restricted stock will become fully vested. At the effective time of the merger, all shares of Company common stock will be cancelled in exchange for a right to receive an amount in cash (subject to any applicable withholding taxes) equal to the per share merger consideration of $23.00 per share.

• Phantom Stock Appreciation Rights. Certain NTS executive officers hold phantom stock appreciation rights granted pursuant to NTS’s 2010 Long-Term Incentive Plan (the “LTIP”). Pursuant to the LTIP, each vested phantom stock appreciation right will be cancelled in the merger in exchange for the right to receive an amount in cash (subject to any applicable withholding taxes) equal to the product of the excess of the $23.00 per share merger consideration over the applicable grant price per phantom stock

5

appreciation right. On October 23, 2012, the compensation committee of the NTS board of directors exercised its discretion to accelerate the vesting of all phantom stock appreciation rights in connection with a change of control occurring before October 23, 2014. Accordingly, all outstanding and unvested phantom stock appreciation rights are expected to vest in the merger and be cancelled in exchange for the aforementioned consideration.

• Supplemental Employee Retirement Plan. Certain NTS executive officers are participants in NTS’s 2006 Amended and Restated Supplemental Executive Retirement Plan, as Amended and Restated effective as of December 31, 2008 (the “SERP”). All unvested benefits of the executive officers in benefits granted under the SERP will become fully vested for participants with ten or more years of service with NTS upon the closing of the merger. Douglas Briskie (Chief Strategy Officer), Derek Coppinger (Chief Operations Officer), William McGinnis (Chief Executive Officer) and Dwight Moore (Chief Marketing and Sales Officer) have ten or more years of service with NTS, and the benefits granted to them under the SERP will become fully vested in connection with the merger. All vested benefits under the SERP will become payable in connection with the closing of the merger pursuant to the terms of the SERP.

• Change in Control Agreements. NTS has entered into change in control agreements with certain of its executive officers. The agreements provide that the executive officers could be entitled to certain severance benefits following a change in control of NTS, if either their employment is terminated by NTS without cause or they resign from their employment for good reason following certain adverse material changes to the terms of their employment. The merger qualifies as a change in control of NTS pursuant to the change in control agreements. Pursuant to the change in control agreement, if an executive officer experiences a qualifying termination of employment within twelve months following a change in control of NTS, he will receive a payment equal to two times his “annual compensation” (as defined in the change in control agreement), the same percentage of Company-paid health insurance benefits as were provided before the change in control for two years after termination of employment, and full accelerated vesting of all outstanding stock options. If the qualifying termination of employment occurs between twelve and twenty-four months following a change in control of NTS, the executive officer will receive a payment equal to one times his annual compensation, the same percentage of Company-paid health insurance benefits as were provided before the change in control for one year after termination of employment, and full accelerated vesting of all outstanding stock options. With respect to Michael El-Hillow, however, NTS’s Chief Financial Officer, upon a qualifying termination of employment within twelve months following a change in control of NTS, he will receive a payment equal to one times his “annual compensation” (as defined in the change in control agreement) and the same percentage of Company-paid health insurance benefits as were provided before the change in control for one year after termination of employment.

• Raffy Lorentzian Letter Agreement. NTS entered into a Letter Agreement dated April 5, 2012 (the “Letter Agreement”) with Raffy Lorentzian, former Chief Financial Officer of NTS, regarding his separation from NTS, which occurred on July 31, 2012 (the “termination date”). Under the Letter Agreement, if a change in control event occurs within eighteen months following the termination date, Mr. Lorentzian will be entitled to payment of $220,420 (which is equal to one year’s base salary), or a prorated portion of that amount if the change in control event occurs between 19 and 36 months following the termination date. The merger qualifies as a change in control of NTS pursuant to the Letter Agreement. Based on a change in control occurring before February 2014, Mr. Lorentzian will receive a lump sum payment of $220,420 within 30 days of the closing of the merger.

• In addition, pursuant to the terms of the merger agreement, Parent has agreed to cause the surviving corporation to indemnify NTS’s current and former directors and officers for six years following the effective time of the merger and to provide for director and officer liability insurance coverage for six years following the effective time. Parent has also agreed to cause the surviving corporation to provide certain post-closing employee benefits to continuing employees of NTS for twelve months following the effective time.

Conditions to the Merger (Page 78)

A number of conditions must be satisfied before the merger will be completed. These include, among others:

• any applicable waiting period (and any extension thereof) under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, referred to as the “HSR Act,” shall have expired or been terminated;

• the receipt of the approval of the merger agreement proposal by NTS shareholders;

• the absence of any injunction or other court order or legal or regulatory restraint that prevents the consummation of the merger or any law or order that prohibits or makes the merger illegal;

• the absence of any action by any governmental authority or by any other person that has a reasonable likelihood of success and that, if successful, would result in a material adverse effect (as defined in 67);

• each party’s respective representations and warranties in the merger agreement being true and correct as of the date of the merger agreement and as of the closing date (or, if made as of an earlier date, as of such earlier date) in the manner described in “The Merger Agreement — Conditions to the Merger”;

• each party’s respective performance of its covenants in the manner described in “The Merger Agreement — Conditions to the Merger”; and

• the absence since August 15, 2013 of any event or circumstance that has had or would reasonably be expected to have a material adverse effect.

Each of Parent, Merger Sub and NTS may waive any of the conditions to its respective obligation to consummate the merger at or prior to the effective time and complete the merger even though one or more of these conditions have not been met. Neither Parent nor NTS can give any assurance that all of the conditions of the merger will be either satisfied or waived or that the merger will occur. Consummation of the merger is not subject to a financing condition.

Restrictions on Soliciting Other Acquisition Proposals (Page 72)

Under the merger agreement, NTS has agreed that it will not, and shall not permit or authorize any of its subsidiaries or representatives to, directly or indirectly:

• initiate, solicit, endorse, propose, encourage or take any other action to facilitate (including by way of furnishing information) any proposals, offers or inquiries with respect to, that constitute, or would reasonably be expected to lead to, an “acquisition proposal” (as defined on page 74);

• enter into, engage, continue or participate in any negotiations concerning, or provide any confidential information or data to, or have any discussions with, any person relating to an acquisition proposal or any proposal or offer that would reasonably be expected to lead to an acquisition proposal;

• approve, endorse or recommend or propose to approve, endorse or recommend, any acquisition proposal;

• approve, endorse or recommend, or propose to approve, endorse or recommend, or execute or enter into, any letter of intent, agreement in principle, merger agreement, acquisition agreement, option agreement or other similar agreement relating to any acquisition proposal or any proposal or offer that has a primary purpose of effectuating, or would reasonably be expected to lead to, an acquisition proposal;

• make or authorize any statement, propose, resolve or agree to do any of the foregoing relating to any acquisition proposal;

• make a “change in board recommendation” (as defined on page 74); or

7

• terminate, waive, amend, release or modify any provision of any existing confidentiality agreement or standstill agreement to which we or any of our subsidiaries is a party with respect to any acquisition proposal or potential acquisition proposal.

Notwithstanding these restrictions, at any time prior to obtaining shareholder approval of the merger agreement proposal, NTS may provide information to a person making an acquisition proposal and also engage in negotiations and discussions with any such person if:

• the NTS board of directors determines in good faith, after consultation with outside legal counsel, that failure to take such action would be inconsistent with its fiduciary duties under applicable law;

• the NTS board of directors determines, in good faith, based on the information then available and upon the recommendation of the special committee (after consultation with the special committee’s independent financial advisor and outside legal counsel), that such acquisition proposal constitutes a “superior proposal” (as defined on page 74);

• such acquisition proposal is bona fide, written and not a result of a breach or violation of any of the restrictions in the merger agreement relating to acquisition proposals; and

• NTS follows certain procedures set forth in the merger agreement.

Ability to Change Board Recommendation / Acquisition Proposals (Page 74)

The merger agreement provides that, subject to certain exceptions, the NTS board of directors may not take any of the following actions (any such action being referred to as a “change in board recommendation”):

• withhold, withdraw, modify or qualify, or propose publicly to withhold, withdraw, modify or qualify, in a manner adverse to Parent or Merger Sub, the approval of the merger agreement and the merger or the recommendation of the NTS board in favor thereof (the “board recommendation”) or take any action or make any statement in connection with the special meeting inconsistent with such approval or board recommendation;

• adopt, approve, endorse, recommend, or otherwise declare advisable or propose to adopt, approve, endorse, recommend, or otherwise declare advisable, publicly or otherwise, any acquisition proposal;

• fail to publicly reaffirm the board recommendation within three business days after Parent or Merger Sub so requests in writing;

• fail to recommend against any acquisition proposal within five business days (other than an acquisition proposal described in next bullet below for which the Company shall have ten business days);

• fail to recommend, in a Solicitation/Recommendation Statement on Schedule 14D-9, against any acquisition proposal subject to Regulation 14D under the Exchange Act, within ten business days after the commencement of any such acquisition proposal;

• fail to include the board recommendation in the proxy statement to be distributed to shareholders in connection with the merger;

• cause or permit NTS or any of its subsidiaries to enter into any letter of intent, memorandum of understanding, agreement in principle or similar document or contract constituting or relating to any acquisition proposal (other than a confidentiality agreement entered into in accordance with, and meeting the requirements described above under “The Merger Agreement — Restrictions on Soliciting Other Acquisition Proposals”);

• make any other public statement that is inconsistent with the board recommendation; or

• resolve, agree or propose to take any of the foregoing actions.

8

However, prior to obtaining shareholder approval of the merger agreement proposal, the NTS board of directors may, under specified circumstances change, its recommendation with respect to the merger agreement and, with respect to a “superior proposal” (as defined on page 74), terminate the merger agreement.

In general, the NTS board of directors may effect a change in board recommendation in response to either a superior proposal or an “intervening event” (as defined on page 76) if: (i) the NTS board of directors determines in good faith after consultation with outside legal counsel that the failure to do so would be inconsistent with its fiduciary duties; and (ii) NTS follows certain procedures set forth in the merger agreement, including providing Parent with the matching and negotiation right provided for therein.

Additionally, at any time prior to obtaining shareholder approval of the merger agreement proposal, the NTS board of directors may terminate the merger agreement and concurrently enter into a definitive acquisition agreement with respect to a superior proposal if: (i) NTS receives an unsolicited bona fide written acquisition proposal from any person that is not withdrawn and that the NTS board of directors concludes in good faith constitutes a superior proposal and did not otherwise result from a breach of any of the restrictions in the merger agreement relating to acquisition proposals; (ii) NTS follows certain procedures set forth in the merger agreement, including providing Parent with the matching and negotiation right provided for therein; and (iii) concurrently with termination of the merger agreement, NTS pays Parent an $11.0 million termination fee.

Termination of the Merger Agreement (Page 79)

In general, the merger agreement may be terminated at any time prior to the effective time of the merger, whether before or after the approval of the merger agreement proposal by NTS shareholders, in the following ways:

• by mutual written consent of NTS and Parent;

• by either NTS or Parent if:

• the closing of the merger agreement shall not have been consummated by 5:00 p.m. Eastern time on February 15, 2014, referred to as the “end date,” except that such right to terminate is not available (i) to any party whose breach of any covenant or obligation under the merger agreement has been the proximate cause of, or resulted in, the failure of the closing to occur by the end date or (ii) to NTS if, at the time of such intended termination by NTS, either Parent or NTS could terminate the merger agreement because NTS shareholders shall have failed to approve the merger agreement proposal at the special meeting (after giving effect to all adjournments or postponements thereof);

• NTS shareholders shall have failed to approve the merger agreement proposal at the special meeting (after giving effect to all adjournments or postponements thereof);

• a (i) court or other governmental authority shall have issued a judgment, order or taken other action enjoining or otherwise prohibiting any of the transactions contemplated in the merger agreement and such judgment, order or other action shall have become final and nonappealable or (ii) if there shall be any applicable law that makes consummation of the merger illegal or otherwise prohibits it, provided that such right to terminate is not available to any party that does not use reasonable best efforts to contest, appeal and remove such judgment, order or other action;

• by NTS if:

• Parent or Merger Sub has breached any representation, warranty, covenant or agreement contained in the merger agreement, or if any representation or warranty of Parent or Merger Sub shall have become untrue or incorrect, such that the closing conditions applicable to Parent or Merger Sub would not be satisfied, if occurring or continuing at the effective time, and such breach or failure to be true and correct is not cured by the earlier of the end date or 30 calendar days following

9

receipt of written notice of such breach or failure (or such longer period to which NTS may agree), except that such right to terminate is not available to NTS if, at the time of such termination, there exists a material breach of any representation, warranty, covenant or agreement of NTS contained in the merger agreement;

• before receipt of the approval of the merger agreement proposal by NTS shareholders, (i) the NTS board of directors authorizes NTS to enter into a definitive acquisition agreement with respect to a superior proposal, (ii) NTS has complied with each of its obligations concerning the consideration of other acquisition proposals and (iii) NTS simultaneously enters into a definitive acquisition agreement with respect to such superior proposal and pays the $11.0 million termination fee to Parent; or

• all of the following three events have occurred: (i) NTS has satisfied (or Parent has waived) each of the conditions to Parent’s and Merger Sub’s obligations to consummate the merger, (ii) NTS has indicated in writing that it is ready, willing and able to consummate the merger on the second business day after the satisfaction or waiver of all conditions to the merger, and (iii) Parent and Merger Sub fail to consummate the merger within two business days of such date;

• by Parent if:

• the NTS board of directors effects a change in board recommendation (see “The Merger Agreement — Ability to Change Board Recommendation / Acquisition Proposals” above), NTS breaches or fails to perform any of its material obligations relating to the calling the special meeting of shareholders or the consideration of other acquisition proposals, or NTS or the NTS board of directors shall have formally resolved or publicly authorized or proposed to take any of the foregoing actions; or

• excluding breaches covered by the previous bullet point, NTS has breached any representation, warranty, covenant or agreement contained in the merger agreement, or if any representation or warranty of NTS shall have become untrue or incorrect, such that the closing conditions applicable to NTS would not be satisfied, if occurring or continuing at the effective time, and such breach or failure to be true and correct is not cured by the earlier of the end date or 30 calendar days following receipt of written notice of such breach or failure (or such longer period to which Parent may agree), except that such right to terminate is not available to Parent if, at the time of such termination, there exists a material breach of any representation, warranty, covenant or agreement of Parent contained in the merger agreement.

Fees and Expenses (Page 80)

If the merger agreement is terminated in certain circumstances described under “The Merger Agreement — Fees and Expenses”:

• NTS may be obligated to pay to Parent a termination fee of $11.0 million;

• NTS may be obligated to reimburse Parent and its affiliates for all of the reasonable out of pocket fees and expenses incurred by Parent or Merger Sub or on their behalf in connection with the merger agreement, up to a maximum of $7.5 million; or

• Parent may be obligated to pay to NTS a “reverse” termination fee of $19.0 million.

Limited Guaranty (Page 81)

Concurrently with the execution of the merger agreement, Aurora Equity Partners IV L.P. and Aurora Overseas Equity Partners IV L.P. (each, a “guarantor” and, collectively, the “guarantors”) entered into a Limited Guaranty with NTS pursuant to which, among other things, each such guarantor has unconditionally agreed to guarantee, on a several and not joint basis, subject to the terms and conditions set forth in the Limited Guaranty,

10

the obligations of Parent to make any payments required to be made by Parent under the merger agreement (other than payment of the merger consideration), up to a maximum amount equal to the guarantors’ respective pro rata portions of the $19.0 million “reverse” termination fee described above. The guarantors are affiliates of Parent.

Specific Performance (Page 81)

Parent and Merger Sub may sue in equity for specific performance and/or to obtain an injunction to prevent breaches of the merger agreement by NTS and to enforce specifically the terms and provisions of the merger agreement.

NTS is only entitled to specific performance (i) to cause Parent or Merger Sub to draw down the financing under the equity commitment letter, or to consummate the merger, provided certain conditions are satisfied (see “The Merger Agreement — Specific Performance”); and (ii) to cause Parent to draw down the debt financing (or, if substitute financing is obtained, to draw down on such substitute financing), provided certain conditions are satisfied (see “The Merger Agreement — Specific Performance”). Parent is under no obligation to bring an action against any of the parties to the debt commitment letter to fund the debt financing.

If the “reverse” termination fee has been paid by or on behalf of Parent, Merger Sub or the guarantors, then neither the Company nor any of its affiliates will be entitled to seek or obtain equitable relief, including specific performance to cause Parent to draw down on its financing commitments in the manner described above.

Regulatory Matters (Page 52)

While one of the mutual conditions to closing is that any applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (“HSR Act”) shall have expired or been terminated, Parent and NTS have determined that no filing is required under the HSR Act in connection with the transactions contemplated by the merger agreement.

Effect of the Merger (Page 27)

If the merger is completed, NTS common stock will no longer be listed on the NASDAQ Global Market and will be deregistered under the Securities Exchange Act of 1934, as amended, referred to as the “Exchange Act,” and NTS will no longer file periodic reports with the SEC.

Dissenting Shareholder Rights (Page 63)

If you do not wish to accept the $23.00 per share merger consideration in the merger, you have the right under California law to demand that NTS repurchase your shares at the fair market value as determined under Section 13 of the California General Corporation Law. The shares subject to such purchase are called “dissenting shares.” In general, to preserve your dissenters’ rights, you must:

• vote your shares of NTS common stock “AGAINST” approval of the merger agreement proposal;

• deliver a written demand to NTS or its transfer agent for purchase of your shares, no later than the date of the special meeting;

• submit the dissenting shares for endorsement in accordance with Section 1302 of the California General Corporation Law; and

• comply with the other provisions of Chapter 13 of the California General Corporation Law.

The text of the California General Corporation Law governing dissenters’ rights is attached to this proxy statement as Annex C. Your failure to comply with the procedures described in Annex C will result in the loss of your dissenters’ rights.

Litigation Relating to the Merger (Page 62)

On August 23, 2013, one week after the announcement of the merger, a putative shareholder class action lawsuit, entitled Elias v. National Technical Systems, Inc., Case No. BC519271, was filed in the Superior Court of the State of California, Los Angeles County, against NTS, the members of NTS’s board of directors, Aurora Capital Group, Parent, and Nest Merger Sub, Inc. (“Merger Sub”). The lawsuit asserts a claim for breach of fiduciary duty against the members of NTS’s board of directors. The lawsuit also alleges that NTS has not provided sufficient information about the merger to shareholders. The lawsuit further asserts that NTS, Aurora Capital Group, Parent, and Merger Sub aided and abetted the alleged breaches of fiduciary duty. The lawsuit seeks to enjoin the consummation of the merger, damages, costs, attorneys’ and experts’ fees, and any other relief the court may deem proper. Each of the defendants believes that the lawsuit is without merit and intends to defend it vigorously. A status conference has been scheduled for November 6, 2013.

QUESTIONS AND ANSWERS ABOUT THE SPECIAL MEETING AND THE MERGER

The following questions and answers briefly address some questions you may have regarding the special meeting, the merger agreement and the merger. These questions and answers may not address all questions that may be important to you. Please refer to the more detailed information contained elsewhere in this proxy statement, the appendices to this proxy statement and the other documents NTS refers to in this proxy statement.

Q: Why am I receiving this proxy statement?

A: The NTS board of directors has agreed to the acquisition of NTS by Parent under the terms of the merger agreement that is described in this proxy statement. A copy of the merger agreement is attached to this proxy statement as Annex A. In order to complete the merger, NTS shareholders must vote to approve the proposal to approve the merger agreement and the transactions contemplated thereby, including the merger (which we refer to as the “merger agreement proposal”). NTS will hold a special meeting of its shareholders to obtain this vote. You are receiving this proxy statement in connection with the solicitation of proxies to be voted at the special meeting or at any adjournments thereof to approve the merger agreement.

You should carefully read this proxy statement, including its annexes and the other documents we refer to in this proxy statement, because they contain important information about the merger, the merger agreement and the special meeting of NTS shareholders. The enclosed voting materials allow you to vote your shares without attending the special meeting.

Your vote is very important. We encourage you to vote as soon as possible.

Q: What am I being asked to vote on?

A: You are being asked to vote to approve the merger agreement proposal. As a result of the merger, NTS will become a wholly-owned subsidiary of Parent, and NTS common stock will cease to be listed on the NASDAQ Global Market, will not be publicly traded and will be deregistered under the Securities Exchange Act of 1934, as amended.

You are also being asked to vote, on an advisory (non-binding) basis, upon specified compensation that may become payable to the named executive officers of NTS in connection with the merger, and to vote upon a proposal to adjourn the special meeting to a later date, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the merger agreement proposal.

Q: How does the NTS board of directors recommend that I vote?

A: The NTS board of directors unanimously recommends that you vote:

• “FOR” the merger agreement proposal;

• “FOR” the advisory (non-binding) proposal to approve specified compensation that may become payable to the named executive officers of NTS in connection with the merger; and

• “FOR” the proposal to adjourn the special meeting to a later date, if necessary or appropriate.

Q: What should I do now?

A: After carefully reading and considering the information contained in this proxy statement, including the appendices, please vote your shares of NTS common stock by either marking, signing and dating the enclosed proxy card and returning it in the postage prepaid envelope provided as soon as possible or promptly submitting your proxy by telephone or over the Internet following the instructions on the proxy card.

13

Q: What happens if I abstain from voting?

A: If you abstain from voting on the merger agreement proposal, it will have the same effect as a vote “AGAINST” this proposal.

Abstentions will have no effect on the outcome of the vote on the proposal to approve, on an advisory (non-binding) basis, the specified compensation that may become payable to the named executive officers of NTS in connection with the merger; however, approval of this proposal also requires the affirmative vote of a majority of the shares necessary to constitute a quorum and, therefore, abstentions could prevent the approval of the proposal because they do not count as affirmative votes.

Abstentions will have the same effect as a vote “AGAINST” the proposal to adjourn the special meeting.

Q: Will my shares be voted if I do not provide my proxy?

A: Under stock market rules currently in effect, brokerage firms and nominees have the authority to vote their customers’ unvoted shares on certain “routine” matters if the customers have not furnished voting instructions within a specified period prior to the special meeting. However, the proposals to be voted upon at the special meeting are not considered “routine” matters and hence brokerage firms and nominees will not be able to vote the shares of customers from whom they have not received voting instructions.

If you hold your shares directly in your own name, they will not be counted as shares present for the purposes of determining the presence of a quorum or be voted if you do not provide a proxy or attend the special meeting and vote the shares yourself.

Q: If my shares are held in “street name” by my broker, how do I vote?

A: Your broker will vote your shares for you provided you instruct your broker how to vote your shares. You should follow the procedures provided to you by your broker regarding how to instruct your broker to vote your shares. Failure to instruct your broker how to vote your shares will result in a broker non-vote.

Q: What is a broker non-vote?

A: Broker non-votes occur when shares held by a broker are not voted with respect to a proposal because (i) the broker has not received voting instructions from the beneficial owner of the shares and (ii) the broker lacks the authority to vote the shares at the broker’s discretion. Broker non-votes will be counted as shares present and entitled to vote for the purposes of determining the presence of a quorum on each of the proposals to be voted on at the special meeting. With respect to the merger agreement proposal, the shares represented by broker non-votes will have the same effect as a vote “AGAINST” the proposal because holders of a majority of the outstanding shares of NTS common stock entitled to vote must vote in favor of this proposal. “Broker non-votes” will have no effect on the proposal to approve, on an advisory (non-binding) basis specified compensation that may become payable to the named executive officers of NTS in connection with the merger because the affirmative vote of a majority of the shares represented at the meeting and voting is required to pass the proposal. Broker non-votes will have the same effect as a vote “AGAINST” the proposal to adjourn the special meeting to a later date, if necessary or appropriate, if the shares held by the broker are voted on one or both of the other proposals but not on this proposal, but broker non-votes will have no effect on the outcome of this proposal if the shares held by the broker are not voted on any of the proposals.

Q: What will I receive in the merger?

A: As a result of the merger, NTS shareholders will receive $23.00 in cash, without interest and less applicable withholding taxes, for each share of NTS common stock they own immediately prior to the effective time of the merger, except for shareholders who properly exercise dissenters’ rights.

Q: How does the per share merger consideration compare to the market price of NTS’s common stock prior to announcement of the merger?

A: The per share merger consideration represents a premium of approximately 39% to NTS’s closing stock price on August 15, 2013, the last full trading day before the public announcement of the merger.

14

Q: Will the merger be taxable to me?

A: Yes. The exchange of shares of NTS common stock for cash by a U.S. Holder (as defined on page 49) will be taxable to such U.S. Holder. A U.S. Holder will recognize gain or loss for federal income tax purposes in an amount equal to the difference between the cash it receives pursuant to the merger and its adjusted tax basis in its shares of NTS common stock exchanged therefor. The exchange of shares of NTS common stock by a non-U.S. Holder (as defined on page 50) could be subject to U.S. federal income tax under certain circumstances. See “The Merger — Material U.S. Federal Income Tax Consequences of the Merger” on page 50. Shareholders should consult their own tax advisors regarding the U.S. federal income tax consequences relating to the merger in light of their particular circumstances and any consequences arising under the laws of any state, local or foreign taxing jurisdiction.

Q: Do any of the Company’s directors or executive officers have interests in the merger that may differ from, or be in addition to, my interests as a shareholder?

A: Yes. In considering the recommendation of the board of directors with respect to the merger agreement proposal, you should be aware that the Company’s directors and executive officers may have interests in the merger that are different from, or in addition to, the interests of our shareholders generally. The board of directors was aware of and considered these interests, among other matters, in evaluating and negotiating the principal terms of the merger agreement and in unanimously recommending that the merger agreement be approved by the shareholders of the Company. See “The Merger — Interests of NTS Executive Officers and Directors in the Merger” beginning on page 52.

Q: When do NTS and Parent expect the merger to be completed?

A: NTS and Parent are working to complete the merger as quickly as practicable. However, we cannot predict the exact timing of the completion of the merger because it is subject to a number of conditions. See “The Merger Agreement — Conditions to the Merger” beginning on page 78. We hope to complete the merger before the end of 2013.

Q: When and where is the special meeting?

A: The special meeting will be held on [                    ], 2013, at [            ], at [            ] local time.

Q: Who may attend the special meeting?

A: Only shareholders of record who owned our common stock as of the close of business on September 20, 2013, the record date for the special meeting, or their duly authorized proxies have the right to attend the special meeting. To gain admittance, you must present a valid photo identification, such as a driver’s license or passport. If your shares of NTS common stock are held through a broker, bank or other nominee, please bring to the special meeting a copy of your brokerage statement evidencing your beneficial ownership of NTS common stock and a valid photo identification. Please note that cameras, recording devices and other electronic devices will not be permitted at the special meeting.

Q: Who may vote at the special meeting?

A: Only holders of record of NTS common stock as of the close of business on September 20, 2013, the record date for the special meeting, may vote at the special meeting. As of the record date, NTS had [                    ] outstanding shares of NTS’s common stock entitled to vote on the transaction.

Q: What vote is required to approve the merger agreement proposal?

A: In order to approve the merger agreement proposal, holders of at least a majority of the outstanding shares of NTS common stock entitled to vote thereon must vote in favor of this proposal.

15

Q: What vote is required to approve, on an advisory (non-binding basis), specified compensation that may become payable to the named executive officers of NTS in connection with the merger?

A: In order to approve, on an advisory (non-binding basis), the specified compensation that may become payable to the named executive officers of NTS in connection with the merger, a majority of the shares represented and voting at the special meeting (which shares voting affirmatively also constitute at least a majority of the required quorum) must approve the proposal.

Q: What vote is required to approve the proposal to adjourn the special meeting to a later date, if necessary or appropriate?

A: Approval of the proposal to adjourn the special meeting to a later date, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the merger agreement proposal requires approval of a majority of the shares represented at the special meeting, either in person or by proxy, whether or not a quorum is present.

Q: Who is soliciting my proxy?

A: This proxy solicitation is being made and paid for by NTS. In addition, we have retained [            ] to assist in the solicitation of proxies for a base fee not to exceed $[            ] plus reasonable out-of-pocket expenses. We have also agreed to indemnify [            ] for specified liabilities and expenses. Our directors, officers and employees may also solicit proxies by mail, in person or by telephone or other means of electronic communication. We will not pay these individuals for their solicitation activities but will reimburse them for their reasonable out-of-pocket expenses. Brokers and other custodians, nominees and fiduciaries will be requested to forward proxy-soliciting material to the owners of stock held in their names, and NTS will reimburse such brokers and other custodians, nominees and fiduciaries for their reasonable out-of-pocket costs.

Q: What does it mean if I get more than one proxy card?

A: If your shares are registered in multiple accounts with one or more brokers and/or our transfer agent, you will receive more than one proxy card. If you are submitting your proxy by completing and returning your proxy card, please complete and return each of the proxy cards you receive to ensure that all of your shares are voted.

Q: What is a “quorum”?

A: A “quorum” will be present at the special meeting if the holders of a majority of the outstanding shares of NTS common stock entitled to vote on the record date are represented in person or by proxy. This quorum of NTS shares must be present at the special meeting, in person or by proxy, in order for the special meeting to be held.

Q: If I have given a proxy, may I subsequently change my vote?

A: Yes. Until your proxy is voted at the special meeting, you can revoke your proxy and change your vote in any of the following ways:

• by giving written notice of the revocation to the Secretary of NTS;

• by properly submitting another proxy by mail, telephone or the Internet, with a later date; or

• by voting in person at the special meeting (if your shares are registered directly on the books of NTS and not held through a broker, bank or other nominee).

16

Your attendance at the special meeting will not in and of itself constitute a revocation of your proxy.

If you have instructed a broker, bank or other nominee to vote your shares, you must follow the procedures provided by your broker, bank or nominee to change those instructions.

Q: Will I have dissenters’ rights as a result of the merger?

A: Yes. You have the right to demand that NTS repurchase your shares at the fair market value determined under Section 13 of the California General Corporation Law. The shares subject to such purchase are called “dissenting shares.” In general, to preserve your dissenters’ rights, you must:

• vote your shares of NTS common stock “AGAINST” approval of the merger agreement proposal;

• deliver a written demand to NTS or its transfer agent for purchase of your shares, no later than the date of the special meeting;

• submit the dissenting shares for endorsement in accordance with Section 1302 of the California General Corporation Law; and

• comply with the other provisions of Chapter 13 of the California General Corporation Law.

The text of the California General Corporation Law governing dissenters’ rights is attached to this proxy statement as Annex C. Your failure to comply with the procedures described in Annex C will result in the loss of your dissenters’ rights.

Q: What happens if I sell my shares of common stock before the special meeting?

A: The record date for the special meeting is September 20, 2013, which is earlier than the date of the special meeting. If you held your shares of NTS common stock on the record date for the special meeting, you will retain your right to vote at the special meeting. If you transfer your shares of NTS common stock after the record date for the special meeting but prior to the date on which the merger is consummated, you will lose the right to receive the per share merger consideration for the shares of NTS’s common stock you have sold. The right to receive the per share merger consideration will pass to the person who owns your shares of NTS common stock when the merger is consummated.

Q: What will happen to NTS. if the merger agreement is proposal is not approved?

A: If the merger agreement proposal is not approved, the merger will not be consummated and NTS shareholders will not receive any payment for their shares. NTS will remain an independent public company, and NTS would expect to be operated by management in a manner similar to that in which NTS is being operated today. See “The Merger — Effect on NTS if the Merger is Not Completed.”

Q. After the special meeting, how can I determine whether the merger agreement proposal has been approved by NTS shareholders?

A. Promptly after the special meeting, NTS will issue a press release announcing whether the merger agreement proposal has been approved by holders of a sufficient number of outstanding shares of NTS common stock.

Q: Should I send in my stock certificates now?

A: No. After the effective time, you will receive written instructions informing you how to send in your stock certificates in order to receive the per share merger consideration. You will receive your cash payment as soon as practicable after receipt of the stock certificates representing the shares of NTS’s common stock that you own, together with the properly completed documents requested in the instructions. Please do not send any stock certificates with your proxy card.

17

Q: Why am I being asked to approve specified merger-related compensation that may become payable to the named executive officers of NTS?

A: The SEC recently approved new rules that require us to seek a vote, on an advisory (non-binding) basis, with respect to certain merger-related executive compensation arrangements, or “golden parachute” compensation that will be paid or may become payable to the Company’s named executive officers.

Q: What will happen if the shareholders do not approve the “golden parachute” compensation at the special meeting?

A: Approval of “golden parachute” compensation that the Company’s named executive officers will or may receive in connection with the merger is not a condition to completion of the merger. The vote with respect to “golden parachute” compensation is on an advisory basis and will not be binding on the Company. Therefore, regardless of whether shareholders approve the “golden parachute” compensation, if the merger agreement is approved by the shareholders and the merger is completed, the “golden parachute” compensation will be paid or may become payable to the Company named executive officers to the extent provided in the merger agreement and in our related compensation plans and agreements.

Q: Who can help answer my questions?

Under the merger agreement, NTS is prohibited from paying any dividend or other distribution on NTS’s common stock prior to the completion of the merger.

The credit facilities of NTS contain restrictions on its ability to make dividend distributions. Those restrictions include a requirement that any dividend or distribution would not trigger a default under any of the financial covenants and would amount to no more than 75% of our consolidated net income for the year in which the dividend distribution is being made.

In fiscal 2013, as part of NTS’s purchase of the 49.9% minority interest that it did not previously own of Unitek Technical Services, Inc., National Quality Assurance, Inc. paid a dividend of $4.5 million on a pro-rata basis to NTS and Ascertiva Group Limited.

Following the consummation of the merger, there will be no further public market for NTS’s common stock.

SPECIAL MEETING OF SHAREHOLDERS

The enclosed proxy is solicited on behalf of the NTS board of directors for use at the special meeting of shareholders or at any adjournment or postponement thereof.

Date, Time and Place

The special meeting will be held on [                    ], 2013, at [        ], at [        ] local time.

Purpose of the Special Meeting

At the special meeting, we will ask the holders of NTS common stock to consider and vote on the following proposals:

1. The merger agreement proposal;

2. An advisory (non-binding) resolution, to approve specified compensation that may become payable to the named executive officers of NTS in connection with the merger; and

3. A proposal to adjourn the special meeting to a later date, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the merger agreement proposal.

At the special meeting, NTS may also transact such other business as may properly come before the special meeting or any adjournment thereof.

Record Date, Shares Entitled to Vote and Quorum

Only holders of record of NTS common stock at the close of business on September 20, 2013, the record date for the special meeting, are entitled to notice of, and to vote at, the special meeting. On the record date, [            ] shares of NTS common stock were issued and outstanding and held by approximately [            ] holders of record.

A quorum of shareholders is necessary to hold a valid special meeting. Under our bylaws, the presence in person or by proxy of the holders of a majority of the shares entitled to vote on the record date shall constitute a quorum for the transaction of business at the special meeting. Broker non-votes and abstentions are counted for purposes of determining whether a quorum is present.

If a quorum is not present at the special meeting, the approval of the proposal to adjourn the special meeting, if necessary or appropriate, requires the affirmative vote of a majority of the shares of NTS common stock represented, in person or by proxy, at the special meeting.

Attendance

Only shareholders of record or their duly authorized proxies have the right to attend the special meeting. To gain admittance, you must present a valid photo identification, such as a driver’s license or passport. If your shares of NTS common stock are held through a broker, bank or other nominee, please bring to the special meeting a copy of your brokerage statement evidencing your beneficial ownership of NTS common stock and a valid photo identification. Please note that cameras, recording devices and other electronic devices will not be permitted at the special meeting.

Vote Required; Abstentions and Broker Non-Votes

Each holder of NTS common stock is entitled to one vote for each share held of record on the record date.

22

Approval of the merger agreement proposal requires the affirmative vote of a majority of the outstanding shares of NTS common stock entitled to vote on the proposal. Broker non-votes and abstentions will have the same effect as a vote “AGAINST” the proposal to approve the merger agreement proposal.

Approval, by non-binding, advisory vote, of specified compensation that may become payable to the named executive officers of NTS in connection with the merger requires the affirmative vote of a majority of the shares of common stock represented either in person or by proxy and voting upon the proposal, which shares voting affirmatively must also constitute at least a majority of the required quorum. Broker non-votes and abstentions have no effect on determining whether the affirmative vote constitutes a majority of the shares represented either in person or by proxy and voting upon the proposal. However, approval of this proposal also requires the affirmative vote of a majority of the shares necessary to constitute a quorum and, therefore, broker non-votes and abstentions could prevent the approval of the proposal because they do not count as affirmative votes.

Approval of the proposal to adjourn the special meeting, whether or not a quorum is present, requires the affirmative vote of the majority of the shares of common stock represented either in person or by proxy. Abstentions will have the same effect as a vote “AGAINST” this proposal. Broker non-votes will have the same effect as a vote “AGAINST” this proposal if the shares held by the broker are voted on one or both of the other proposals but not on this proposal, but broker non-votes will have no effect on the outcome of this proposal if the shares held by the broker are not voted on any of the proposals.

Voting of Proxies

After carefully reading and considering the information contained in this proxy statement, you should either complete, date and sign the enclosed proxy card and mail the proxy card in the enclosed return envelope as soon as possible or promptly submit your proxy by telephone or over the Internet following the instructions on the proxy card so that your shares of common stock are represented at the special meeting, even if you plan to attend the special meeting in person. If you elect to submit your proxy by telephone or via the Internet, you will need to provide the control number set forth on the enclosed proxy card upon which you will be provided the option to vote “FOR,” “AGAINST” or “ABSTAIN” with respect to each of the proposals. If no specification is indicated, all of your shares of common stock represented by valid proxies that have been submitted will be voted “FOR” the proposal to approve the merger agreement proposal, “FOR” the proposal to approve, by non-binding, advisory vote, specified compensation that may become payable to the named executive officers of NTS in connection with the merger and “FOR” any proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies.

Revocability of Proxies

The grant of a proxy on the enclosed form of proxy or submission of a proxy by telephone or over the Internet pursuant to the instructions on the proxy card does not preclude a shareholder from voting in person at the special meeting. Until your proxy is voted at the special meeting, you can revoke your proxy and change your vote in any of the following ways:

• by giving written notice of the revocation to the Secretary of NTS;

• by properly submitting another proxy by mail, telephone or the Internet, with a later date; or

• by voting in person at the special meeting (if your shares are registered directly on our books and not held through a broker, bank or other nominee).

Your attendance at the special meeting will not in and of itself constitute a revocation of your proxy.

If you have instructed a broker to vote your shares, the above-described options for changing your vote do not apply; instead, you must follow the instructions received from your broker to change your vote.

23

Recommendation of the NTS Board of Directors

The NTS board of directors unanimously recommends that you vote:

• “FOR” the merger agreement proposal;

• “FOR” the advisory (non-binding) proposal to approve specified compensation that may become payable to the named executive officers of NTS in connection with the merger; and

• “FOR” the proposal to adjourn the special meeting to a later date, if necessary or appropriate.

Voting by NTS Executive Officers and Directors

As of the record date, NTS executive officers and directors as a group owned and were entitled to vote [        ] shares of NTS’s common stock, which represents approximately [    ]% of NTS’s total common stock outstanding on that date.

Each NTS executive officer and director other than Mr. Justin C. Jacobs (collectively referred to as the “covered directors and officers”) has entered into a voting agreement with Parent, referred to as the “voting agreement,” with respect to all shares of NTS common stock owned of record and beneficially by the covered directors and officers, as set forth in the voting agreement, and any additional shares of common stock and any other voting securities of NTS which the covered directors and officers acquire record and/or beneficial ownership of after the date of the voting agreement (collectively referred to as the “voting agreement shares”). The covered directors and officers collectively own approximately 18% of the outstanding shares of NTS common stock and have agreed to take the following actions, among others, during the term of the voting agreement: (1) vote all voting agreement shares in favor of the merger, the merger agreement and any other matters relating to and/or necessary for consummation of the merger and the other transactions contemplated in the merger agreement; (2) vote all voting agreement shares against any acquisition proposal; (3) vote all voting agreement shares against any other actions that would or could reasonably be expected to adversely affect or delay the merger; and (4) vote all voting agreement shares in favor of any proposal to adjourn the special meeting to a later date if a quorum is not present or if there are not sufficient votes for the adoption of the merger agreement. In addition, each covered director and officer has granted to Parent (and its executive officers and designees), pursuant to the voting agreement, an irrevocable proxy to vote the voting agreement shares in accordance with the foregoing.

Solicitation of Proxies

NTS will bear the cost of solicitation of proxies by us. In addition to soliciting shareholders by mail, NTS directors, officers and employees, without additional remuneration, may solicit proxies in person or by telephone or other means of electronic communication. NTS will not pay these individuals for their solicitation activities but will reimburse them for their reasonable out-of-pocket expenses. Brokers and other custodians, nominees and fiduciaries will be requested to forward proxy-soliciting material to the owners of stock held in their names, and NTS will reimburse such brokers and other custodians, nominees and fiduciaries for their reasonable out-of-pocket costs. Solicitation by NTS directors, officers and employees may also be made of some shareholders in person or by mail, telephone or other means of electronic communication following the original solicitation.

NTS has retained the firm of [            ] to assist in the solicitation of proxies for a base fee not to exceed $[            ] plus reasonable out-of-pocket expenses, and have agreed to indemnify [            ] for specified liabilities and expenses.

Other Matters

NTS does not expect that any matter other than the proposals described in this proxy statement will be brought before the special meeting. If, however, the NTS board of directors properly presents other matters, each

24

of the persons named as a proxy will vote in accordance with his judgment as to matters that he believes to be in the best interests of NTS shareholders. A proxy in the accompanying form or properly submitted by telephone or over the Internet will give authority to William C. McGinnis, our Chief Executive Officer, and Michael El-Hillow, our Chief Financial Officer, to vote on such matters at their respective discretion and they intend to do so in accordance with their best judgment on any such matter.

Adjournment of Special Meeting

Although it is not expected, the special meeting may be adjourned for the purpose of soliciting additional proxies or if a quorum is not present. Our bylaws provide that the special meeting, whether or not a quorum is present, may be adjourned by the affirmative vote of the majority of the shares represented at such meeting, either in person or by proxy. If the special meeting is adjourned to another time or place, notice need not be given of the adjourned meeting if the time and place thereof are announced at the special meeting, unless a new record date for the adjourned meeting is fixed, or unless the adjournment is for more than 45 days from the date set for the special meeting, in which case the NTS board of directors shall set a new record date; notice of any such adjourned meeting shall be given to each shareholder of record entitled to vote at the adjourned meeting in accordance with our bylaws. At any adjourned meeting, NTS may transact any business which might have been transacted at the special meeting.

Householding of Special Meeting Materials

If you share an address with another shareholder, each shareholder at the same address may not receive a separate copy of this proxy statement, though each shareholder in the household will receive a separate proxy card. This process, known as “householding,” reduces the volume of duplicate information received at your household and helps to reduce our expenses.

If you would like to receive your own set of our disclosure documents this year or in future years, follow the instructions described below. Upon such request, we will promptly deliver a separate copy of the proxy materials to you. Similarly, if you share an address with another shareholder and together both of you would like to receive only a single set of our disclosure documents, follow these instructions:

• If your shares are registered in your own name, please contact us at Investor Relations at National Technical Systems, Inc., 24007 Ventura Boulevard, Calabasas, CA 91302 or by calling (818) 591-0776 to inform us of your request.

• If a bank, broker or other nominee holds your shares, please contact your bank, broker or other nominee directly.

26

THE MERGER

This section describes material aspects of the merger agreement and the merger. While NTS believes that the description covers the material terms of the merger agreement and the merger, it may not contain all of the information that is important to you. You should read carefully this entire proxy statement and the other documents referred to in this proxy statement, including the full text of the merger agreement, a copy of which is attached as Annex A hereto, for a more complete understanding of the merger agreement and the merger.

Effect of the Merger

Upon the terms and subject to the conditions of the merger agreement, Merger Sub will merge with and into NTS, with NTS continuing as the surviving corporation. As a result of the merger, NTS will become a wholly-owned subsidiary of Parent, and NTS common stock will no longer be publicly traded. In addition, NTS common stock will be delisted from the NASDAQ Global Market and deregistered under the Securities Exchange Act of 1934, as amended, referred to as the “Exchange Act,” and we will no longer file periodic reports with the SEC on account of NTS common stock. If the merger is completed, you will not own any shares of the capital stock of the surviving corporation.

The time at which the merger will become effective, referred to as the “effective time,” will occur upon the filing of a certificate of merger with the Secretary of State of the State of California (or at such later time as we, Parent and Merger Sub may agree and specify in the certificate of merger).

Effect on NTS if the Merger is Not Completed

If the merger agreement proposal is not approved by NTS’s shareholders or if the merger is not completed for any other reason, NTS shareholders will not receive any payment for their shares of common stock. Instead, NTS will remain an independent public company, our common stock will continue to be listed and traded on the NASDAQ Global Market and registered under the Exchange Act and we will continue to file periodic reports with the SEC on account of our common stock. In addition, if the merger is not completed, NTS expects that management will operate the business in a manner similar to that in which it is being operated today and that NTS shareholders will continue to be subject to the same risks and opportunities to which they are currently subject.

Furthermore, if the merger is not completed, and depending on the circumstances that would have caused the merger not to be completed, it is likely that the price of our common stock will decline significantly. If that were to occur, it is uncertain when, if ever, the price of our common stock would return to the price at which it traded as of the date of this proxy statement.

Accordingly, if the merger is not completed, there can be no assurance as to the effect of these risks and opportunities on the future value of your shares of our common stock. If the merger is not completed, the NTS board of directors will continue to evaluate and review our business operations, properties and capitalization, among other things, make such changes as are deemed appropriate and continue to seek to identify strategic alternatives to enhance shareholder value. If the merger agreement proposal is not approved by NTS shareholders or if the merger is not completed for any other reason, there can be no assurance that any other transaction acceptable to NTS will be offered or that our business, prospects or results of operation will not be adversely impacted.

In addition, under specified circumstances, NTS may be required to reimburse Parent’s expenses or pay Parent a termination fee, or may be entitled to receive a “reverse” termination fee from Parent, upon the termination of the merger agreement, as described under “The Merger Agreement — Effect of Termination of the Merger Agreement” beginning on page 80.

27

Merger Consideration

If the merger is completed, you will receive $23.00 in cash, without interest and less applicable withholding taxes, for each share of NTS common stock that you own immediately prior to the effective time and for which you have not properly exercised dissenters’ rights. After the merger is completed, you will have the right to receive the per share merger consideration, but you will no longer have any rights as a NTS shareholder. NTS shareholders will receive the per share merger consideration after exchanging their NTS stock certificates in accordance with the instructions contained in the letter of transmittal to be sent to all NTS shareholders promptly after the effective time of the merger.

Background of the Merger

The NTS board of directors (also referred to as the “board of directors” or the “board”), with input from senior management, regularly reviews and assesses opportunities to increase shareholder value as part of its ongoing evaluation of NTS’s business. In fiscal 2010, the board adopted a five year strategic plan for NTS designed to deliver shareholder value through growth in the Company’s revenues and net income. The plan contemplated both organic revenue growth from existing businesses, as well as from strategic add-on acquisitions. Following the adoption of the plan, we aggressively pursued acquisitions, acquiring Mechtronic Solutions, Inc. (2010), Lightning Technologies, Inc. (2011), Ingenium Testing, LLC (2011), Garwood Laboratories Inc. (2012) and Unitek Systems, Inc. (in which we acquired a 50.1% interest in 2009 and the remaining 49.9% interest in 2012). The plan also contemplated leveraging economies of scale and market position from our growth in revenue to increase gross margins and profitability.

From time to time, NTS has also received inquiries from financial sponsors and industry participants regarding possible business combination transactions with the Company. On or about June 28, 2010, a director of a private equity fund (referred to as “Financial Buyer A”), at a meeting with our Chairman Don Tringali, orally expressed interest to Mr. Tringali in engaging in exclusive negotiations to acquire all of NTS’s outstanding common stock at a price of $8.70 per share. The trading price for our common stock on the NASDAQ Global Market had ranged from $5.20 to $5.65 for most of the three months leading up to the offer, and over the 10 trading days prior to June 28, 2010 rose to a closing price of $6.89 on June 25, 2010 (the last trading day before the oral offer from Financial Buyer A).

The board of directors considered the oral offer proposed by Financial Buyer A at a special meeting of the board on July 6, 2010 and determined that the offer was not in the best interest of our shareholders. The board believed that the shareholders would recognize better value if the Company continued to execute its five year strategic plan. On July 7, 2010, the board of directors sent a letter to Financial Buyer A thanking it for its interest in the Company, but declining to enter negotiations.

Despite the board of directors’ decision not to enter negotiations, on July 13, 2010 Financial Buyer A sent a written non-binding term sheet to the board proposing to enter into exclusive negotiations to acquire all of the Company’s outstanding common stock at a price of $9.00 per share. The board of directors elected not to enter exclusive negotiations, but given the persistent interest of Financial Buyer A in the Company, the board determined that it would be advisable to explore the opportunities Financial Buyer A presented for NTS and its shareholders. Over the next several months, NTS board members engaged in periodic discussions and meetings with Financial Buyer A.

At about the time NTS received the non-binding term sheet from Financial Buyer A, certain of NTS’s larger shareholders also began expressing their interest in a sale of the Company to the NTS board. On July 16, 2010, at the annual meeting of shareholders, a number of shareholders attended the meeting to express their dissatisfaction with both the price at which the Company’s common stock was trading as well as the limited liquidity of its trading market. They encouraged the board to evaluate options to sell the Company.

On September 8, 2010, a group of our shareholders (referred to collectively as the “13D Group”), including Dr. Jack Lin, who was one of our founders and a director at the time, filed a Schedule 13D with the SEC. The

28

Schedule 13D disclosed the 13D Group’s beneficial ownership of approximately 23% of our common stock and made reference to the 13D Group’s past recommendations to the board to commence a sale process. In this regard, the Schedule 13D also disclosed the 13D Group’s retention of M&A Capital, LLC as its exclusive financial advisor in connection with a potential sale of the shares held by the group “whether effected in one transaction or multiple transactions, and including, without limitation . . . .in a change of the financial structure, control or ownership of all or a portion of the Company.”

On September 21 and 22, 2010, the board of directors met at a regularly scheduled meeting. On the first day of the meeting, the board continued its evaluation of Financial Buyer A’s July proposal. On the following day, the board reviewed an update of management’s five year strategic plan, discussing organic growth expectations and growth by acquisitions and the basis for the underlying assumptions. They also evaluated potential gross margins, the impact of executive compensation on the plan and possible risks to the plan.

On November 19, 2010, NTS received correspondence from Tom Murphy, an investment banker with M&A Capital LLC, indicating that since the 13D Group had filed its Schedule 13D with the SEC on September 9, 2010, he had been approached by other NTS shareholders who favored a sale of the Company and who, together with the 13D Group, owned in excess of a majority of our common stock outstanding at the time. Mr. Murphy stated in his letter that “based upon the unsolicited communications from these other shareholders, we are convinced that an overwhelming majority of NTS’s shareholders support a sale of the Company for at least $9.50 per share.”

At a special meeting of the board of directors that took place on December 7 and 8, 2010, the board of directors continued its evaluation of Financial Buyer A’s July proposal as well as the request from shareholders that the board evaluate a sale of the Company. The directors considered the Company’s prospective value under alternative growth scenarios. Ultimately, after extensive discussion, the board determined that a sale to Financial Buyer A was not in the best interests of NTS’s shareholders at that time and that the shareholders would be better served by the Company continuing to focus on maximizing shareholder value through pursuit of margin expansion and add-on acquisitions as outlined in the Company’s five year strategic plan. The board adopted resolutions formally rejecting the terms proposed by Financial Buyer A in its term sheet. Dr. Jack Lin was the only director to vote in favor of pursuing a potential sale to Financial Buyer A.

On April 7, 2011, Dr. Jack Lin resigned from the NTS board of directors. That same day, the 13D Group filed soliciting material with the SEC disclosing that it intended to nominate an alternate slate of director nominees at the upcoming 2011 annual meeting of shareholders. The soliciting material also stated that the nominees were aligned with the 13D Group in desiring to explore strategic alternatives, including a strategic sale of the Company in order to maximize shareholder value.

In order to infuse the Company with additional capital to pursue its acquisition strategy, on June 27, 2011, the Company entered into a securities purchase agreement with Mill Road Capital, L.P. whereby, in exchange for $14 million, the Company issued to Mill Road Capital L.P.: (i) 933,333 shares of the Company’s common stock; (ii) a 5-year 15% subordinated note in the original principal amount of $7 million; and (iii) a warrant to purchase up to 300,000 shares of the Company’s common stock. In connection with the financing, the Company agreed to grant Mill Road Capital L.P. the right to nominate a director to the Company’s board of directors provided it maintained a minimum ownership of 5% the Company’s common stock. Mill Road Capital, L.P. designated Mr. Justin C. Jacobs as its initial representative on the board of directors. The Company used the net proceeds from the financing for additional strategic acquisitions (including Ingenium Testing in July 2011).

On August 11, 2011, NTS mailed its definitive proxy statement for the 2011 annual meeting of shareholders, which was scheduled to be held on September 27, 2011. The proxy statement included three shareholder proposals, each of which the NTS board recommended a vote “against.” Two of the shareholder proposals were submitted by the 13D Group: a bylaw amendment to fix the size of NTS’ board of directors at nine members, and a second bylaw amendment to provide that the size of NTS’s board of directors could only be modified by a shareholder vote. The third proposal, proposed that the board of directors hire an investment

29

banker to search for a potential buyer of NTS to maximize shareholder value, was submitted by a shareholder who was not a member of the 13D Group. The 13D Group waged a proxy contest in connection with the meeting, nominating an alternative slate of three directors and urging all shareholders to support each of the three aforementioned shareholder proposals.

On September 1, 2011, the Company acquired Lightning Technologies, Inc. (LTI), a provider of testing and engineering services located in Pittsfield, Massachusetts. LTI operated an engineering services and testing laboratory, specializing in the field of lightning protection. The acquisition expanded the Company’s non-defense industry businesses, particularly its aerospace business.

The 2011 annual meeting of shareholders was held on September 27, 2011. The board of directors’ slate of nominees was elected at this meeting, and each of the three shareholder proposals was defeated. However, the proxy holder for the 13D Group did not arrive at the annual meeting until after the polls had closed, and had not previously delivered the proxies he held to the inspector of elections. If the 13D Group had delivered all of its proxies to the inspector of elections prior to the polls closing, the shareholder advisory proposal urging management to retain an investment banking firm and evaluate the potential sale of NTS would have been approved. Following the meeting, NTS issued a press release reporting the voting results of the meeting, in which it stated that the board of directors was “committed to addressing the liquidity concerns brought to [it] by shareholders” and “was open to any strategic options that can maximize value and provide shareholders with the liquidity they desire.”

On December 7, 2011, the board of directors held a regular meeting. At that meeting the board discussed elements of the Company’s strategic growth plan: organic growth, innovation and strategic acquisitions. The board reviewed initiatives in the Company’s innovation program aimed at increasing high gross margin businesses. They also reviewed the acquisition portion of the strategy and discussed the timing and size of acquisitions needed to meet the five year strategic plan. The directors also acknowledged the shareholder request to evaluate the engagement of an investment banker, and requested that Mr. Bill McGinnis, a director and NTS’s Chief Executive Officer, along with Messrs. John M. Gibbons and Justin C. Jacobs identify six prospective investment banking firms with relevant experience in the testing and certification, or aerospace and defense industries for the board of directors to interview.

On January 31 and February 1, 2012, the board of directors met with management for a strategic planning session. During these meetings, the board reviewed and evaluated such things as market dynamics, competition, merger and acquisition activity in the testing and certification industry, business and execution risks, and shareholder communications to the board. The board also discussed with management questions concerning the Company’s opportunities, challenges and goals for fiscal 2013.

On February 2, 2012, the board of directors held a regular meeting. The directors reviewed the key information and strategic initiatives discussed at the strategic planning session. The board also discussed the potential retention of an investment banking firm. Mr. McGinnis reported that he, along with Messrs. Gibbons and Jacobs, had started the process of identifying potential financial advisors for the full board to interview. They were asked to continue with the evaluation and request that the candidates attend upcoming board of director meetings, to allow the full board to evaluate the candidates and obtain current information regarding market dynamics and other views on strategic alternatives for the Company.

Between February and June 2012, the board of directors held preliminary discussions with six prospective financial advisors. The board asked the financial advisors to review the Company’s current position and to discuss potential strategic alternatives for the Company, including strategic growth, a secondary offering of our common stock and a sale of the Company. Each of the prospective financial advisors had substantially similar observations regarding the Company’s strategic alternatives: (i) continuing the Company’s growth strategy would require additional equity capital to finance acquisitions, which may be dilutive to existing shareholders; (ii) in order to address the shareholder liquidity issues the Company would likely have to increase its public float either through a secondary public offering or a series a private placements, each of which presented risks related

30

to the prospective pricing and terms because of the thin trading market and low historical trading prices for the Company’s common stock; and (iii) based on preliminary analysis of prior sale transactions in the industry, a sale of the Company could provide shareholders with a substantial premium to current trading prices. Following those meetings, the board began to focus its strategic efforts on a sale of the Company.

On April 17, 2012, the Company acquired all of the outstanding common stock of Garwood Laboratories, Inc., with testing facilities in Pico Rivera and San Clemente, CA. The acquisition expanded the Company’s client relationships and market share in Southern California as well as the greater Western U.S. region.

On or about April 20, 2012, Mr. Bill McGinnis, was contacted by Aurora Capital Group partners, Messrs. John Mapes and Michael Marino. Messrs. Mapes and Marino briefly introduced their firm and its activity in the aerospace and defense industry to Mr. McGinnis. They suggested that the group meet in person, noting both firms being based in the greater Los Angeles area. On April 30, 2012, Mr. McGinnis and Mr. Doug Briskie, NTS’s Chief Strategy Officer, met with Messrs. Mapes and Marino. At this meeting, the group discussed aerospace and defense industry trends and NTS’s business generally. Messrs. Mapes and Marino also noted at this meeting Aurora Capital Group’s general interest in exploring potential investment opportunities in the aerospace and defense industry.

Over the course of the next month, representatives of Aurora Capital Group expressed further interest to Mr. McGinnis in learning more about the Company and from time to time contacted Mr. McGinnis to further discuss industry trends and NTS’s business generally.

On or about May 22, 2012, Mr. McGinnis received a request from Aurora Capital Group to enter into a non-disclosure agreement in order to allow for a more fulsome review of NTS’s business operations, including access to material non-public information relating to NTS. Representatives of Aurora Capital Group noted to Mr. McGinnis that they were impressed with the Company and interested in a potential acquisition of NTS.

That same day, Mr. McGinnis informed Mr. Donald Tringali, Chairman of the NTS board of directors, of Aurora Capital Group’s request to enter into a non-disclosure agreement with the Company. Mr. Tringali discussed the request with other directors, and the consensus of the directors was that it would be in the best interest of the Company and its shareholders to defer entering into a non-disclosure agreement with Aurora Capital Group until the Company was actively engaged in a process with other potential bidders to solicit interest in a sale of the Company. Accordingly, the Company denied Aurora Capital Group’s request to enter into a non-disclosure agreement, and similarly denied it access to any non-public information relating to the Company.

On July 19, 2012, the board of directors received a preliminary non-binding indication of interest from Aurora Capital Group to acquire the Company for $9.50 per share, in cash, together with a request from Aurora Capital Group for NTS to enter into exclusive negotiations with it for a potential sale of the Company. Aurora Capital Group indicated in its preliminary non-binding indication of interest that it had been following the Company, was impressed with its leadership position and technical capabilities in engineering and testing services and believed that Aurora Capital Group was uniquely positioned to support further growth and development of the Company and to also expeditiously consummate a transaction that provided for certainty and shareholder value. For the three months prior to July 19, 2012, NTS’s common stock had traded in a range of $5.19 to $7.15 on the NASDAQ Global Market, closing at $7.15 on July 18, 2012, the day before the proposal.

The NTS board of directors reviewed Aurora Capital Group’s proposal at its regularly scheduled board meeting on July 24 and July 25, 2012. In connection with that review, and the board’s evaluation of a possible strategic transaction, the board discussed with legal counsel the fiduciary duties of directors in the context of a possible sale or other change of control transactions. The agenda for this meeting also included a further review of potential strategic alternatives for the Company and further meetings with the six prospective financial advisors that the board had met with previously. Following further discussion with each of the six prospective financial advisors, the board narrowed the field to two, one of which was Houlihan Lokey Capital, Inc., referred to as “Houlihan Lokey.” The directors instructed management to meet again with the two remaining prospective

31

financial advisors before the board of directors made a final selection. The board also declined to pursue negotiations with Aurora Capital Group, electing instead to evaluate any sale of the Company in the context of a marketed auction process.

On October 24, 2012, the board of directors held its next regular meeting. At that meeting, the board of directors again evaluated whether to investigate a possible sale of the Company. The directors received a report from management concerning the Company’s progress against its operating budget for the fiscal year, as well as its progress against the five year strategic plan. They discussed the Company’s expected organic growth and acquisition growth, and the assumptions underlying that growth, including the size of available acquisition targets and the capital that would be required to complete such acquisitions. The board also reviewed its prior discussions with the prospective financial advisors at recent board meetings regarding the prospects of a sale transaction. Following discussion regarding the same, the board determined that it would be advisable to form a special committee of disinterested and independent directors (referred to as the “special committee”) whose purpose would be to (i) manage the process of seeking strategic alternatives for the Company, (ii) review and evaluate any potential transaction between the Company and a third party and (iii) take such other actions with respect thereto as authorized by its charter. A special committee was so formed later in the meeting and two disinterested and independent directors of the board were appointed as its initial members: John M. Gibbons and Donald J. Tringali. Those members were given authority to select a third member from the Company’s other disinterested and independent directors, and subsequently appointed John Foster to serve as the third member of the special committee. Pursuant to its charter, the special committee was granted broad authority to, among other things, (i) manage the Company’s efforts to seek and evaluate strategic alternatives, (ii) review and evaluate the terms and conditions, and determine the advisability of, any potential transaction, (iii) negotiate the terms and conditions of a potential transaction, and (iv) recommend to the full board of directors what action, if any, should be taken with respect to a potential transaction. The special committee charter also authorized the special committee to retain counsel and a financial advisor to advise and assist the special committee. At the meeting, Mr. Jacobs, the director representative of Mill Road Capital, L.P., indicated that Mill Road Capital, L.P. wished to preserve its rights as a possible bidder in any sale transaction. As a result, Mr. Jacobs asked not to be considered as a potential member of the special committee and indicated that he planned to recuse himself from portions of any board meetings in which discussions of a sale of NTS were to take place. The special committee subsequently engaged Houlihan Lokey to serve as its financial advisor to assist with exploring a sale of the Company.

On November 8, 2012, the Company purchased the 49.9% minority interest that it did not previously own of Unitek Technical Services, Inc., a consolidated subsidiary. The initial 50.1% interest in Unitek was obtained on November 30, 2009 to broaden the Company’s service offerings to include supply chain management.

During November and December 2012, meetings occurred among Houlihan Lokey, NTS management and the special committee and preparation commenced of the marketing materials that would be used in the solicitation of indications of interest for a sale of the Company. The special committee had initially intended to commence a sale process early in 2013. However, uncertainty over the federal budget and the impact of sequestration on NTS’s aerospace and defense business resulted in a determination by the special committee on January 23, 2013 to delay the solicitation process until the impact of sequestration became more clear.

In May 2013, the special committee met and determined that since market conditions were stabilizing, it was time to initiate the solicitation process. The special committee worked with Houlihan Lokey and management to develop a list of prospective bidders, including both potential strategic bidders comprised of companies that were in the testing and certification industry, or for whom expansion into the testing and certification industry would be a logical extension of their core business, and prospective financial buyers that might have an interest in the Company’s business and had the financial resources to complete a transaction of the size contemplated.

32

In June 2013, in accordance with the special committee’s directives, Houlihan Lokey contacted 194 prospective bidders, consisting of 53 strategic buyers and 141 financial buyers, including Aurora Capital Group and Financial Buyer A. A “teaser” memorandum was distributed to the 114 prospective bidders that expressed interest. The teaser did not identify NTS by name but invited interested parties to enter into a confidentiality agreement and receive a confidential information memorandum concerning the Company’s business and prospects. Confidentiality agreements were secured with 114 prospective bidders (21 of which were strategic buyers and 93 of which were financial buyers), including Aurora Capital Group who entered into a confidentiality agreement on June 5, 2013. The confidential information memorandum was distributed to prospective bidders beginning in June 2013.

Interested bidders were invited to submit indications of interest by July 15, 2013. In the indications of interest, bidders were asked to state an anticipated purchase price based on a cash-free, debt -free enterprise value. Eighteen prospective bidders (4 of which were strategic and 14 of which were financial) submitted indications of interest. The average of the indications submitted by this group, in the special committee’s view, translated to a per share price of approximately $16.45 per share.

The special committee reviewed each of the indications of interest with Houlihan Lokey on July 18, 2013. After discussion, the special committee elected to proceed with seven prospective bidders, one of which was strategic and the other six of which were financial, including Aurora Capital Group. Financial Buyer A submitted an indication of interest in connection with the process, but the bid price was among the lower bids received and Financial Buyer A was not among the seven bidders selected to participate in the next round. The decision on which bidders progressed to the next round was based primarily on the value provided in the indication of interest, with additional consideration given to the bidder’s ability to fund and close the transaction, including financial resources, reputation and experience in completing deals of this size. The seven bidders who were selected to proceed to the next round submitted indications which translated in the special committee’s view to per shares prices of approximately $16.45 to $20.53 per share. Aurora Capital Group submitted the highest initial indication of interest among the 18 that were received, with a proposal which translated in the special committee’s view to a per share purchase price of $20.53 per share, a 216% increase to the per share price proposed by Aurora Capital Group in July 2012.

In connection with its indication of interest, Aurora Capital Group requested that the Company enter into immediate negotiations on an exclusive basis. As an inducement, in addition to its leading price, Aurora Capital Group stated that it was willing and able to sign a definitive agreement and consummate a transaction on an expedited basis. The special committee discussed this request with its legal and financial advisors. After careful consideration, the special committee determined that even though Aurora Capital Group’s indication of interest offered certain advantages in terms of price and timing over the others received, it would be in the best interest of NTS and its shareholders to allow the other 6 bidders to continue in the process and move forward with their due diligence. The special committee denied Aurora Capital Group’s request for exclusivity. The special committee, however, believed that it would be advisable for the Company to commence negotiations regarding a transaction on a non-exclusive basis with Aurora Capital Group.

On July 19, 2013, in accordance with the special committee’s directives, Houlihan Lokey informed Aurora Capital Group of the Company’s willingness to commence negotiations on a non-exclusive basis but also that for an agreement on a transaction to be reached, Aurora Capital Group would be required by the special committee to substantially increase its already leading price and there could be no financing contingency in the definitive merger agreement.

Beginning on July 19, 2013, Parent, a wholly-owned subsidiary of Aurora Pacific Equity Partners, Inc. and an affiliate of Aurora Capital Group, commenced its confirmatory due diligence review of NTS. Parent’s review included legal, accounting, and financial due diligence, more directed and targeted interactions with, and inquiries of, management regarding the business, and a management presentation beginning on July 23, 2013. The other six bidders were also offered the opportunity to schedule management presentations with NTS. Those presentations commenced on July 24, 2013. The other bidders were also provided access to the same diligence materials as Parent.

33

On July 25, 2013, Sheppard Mullin Richter & Hampton, LLP (also referred to as “Sheppard Mullin”), counsel to the special committee, reviewed with the special committee a draft merger agreement to be used in connection with the sale process. Following such review, the special committee approved the delivery of the draft merger agreement to Gibson, Dunn & Crutcher LLP (also referred to as “Gibson Dunn”), counsel to Parent. Later that day, representatives from Sheppard Mullin delivered the draft merger agreement to Gibson Dunn.

On August 2, 2013, Gibson Dunn returned a mark-up of the draft merger agreement to Sheppard Mullin.

On August 4, 2013, the special committee met telephonically with representatives of Sheppard Mullin and Houlihan Lokey to review Gibson Dunn’s mark-up of the draft merger agreement. At the meeting, representatives of Sheppard Mullin reviewed the key terms of the draft merger agreement, and received instruction from the special committee on its position with respect to such terms, including the fiduciary out, conditions to closing, termination rights and termination fee.

Between August 5, 2013 and August 15, 2013, the parties continued to negotiate the terms of the draft merger agreement and the related ancillary agreements, with Gibson Dunn and Sheppard Mullin exchanging multiple drafts and holding telephonic conference calls almost on a daily basis to discuss open terms in the draft merger agreement and their client’s respective positions. Among the provisions most highly negotiated were the fiduciary out, conditions to closing, termination rights and termination fee. During this period, Sheppard Mullin kept the special committee and full board of directors fully apprised of the status of its negotiations and received direction and input from the special committee on all key terms in the draft merger agreement.

On August 9, 2013, the one strategic bidder withdrew from the process, citing a lack of fit with its core business. The remaining six bidders, including Parent (all of which were financial buyers) continued to diligence the Company and, in the case of Parent, continued negotiations on the draft merger agreement.

On August 9, 2013, the board of directors (other than Mr. Jacobs) met to receive an update from the special committee. Mike El-Hillow, Chief Financial Officer, was in attendance as well as representatives of Sheppard Mullin and Houlihan Lokey. The special committee reviewed the status of the sale process in general, including the decision of the sole remaining strategic bidder to withdraw. Messrs. McGinnis and El-Hillow, along with the representatives of Houlihan Lokey, discussed each of the remaining bidders, including the results of management meetings and the level of activity in the due diligence process. The board, in consultation with Houlihan Lokey, discussed whether any of the remaining bidders was likely to offer a higher price than Parent. They discussed the values in the initial indications of interest relative to prior sale transactions in the industry. The board considered the financial position and prior acquisition history of the bidders. The board also weighed the risk of deferring a potential sale to Parent while the remaining bidders continued their due diligence, including the risk that Parent would withdraw its offer, that the business could encounter unforeseen difficulties, and that changes in the capital markets would make it more difficult or costly for a financial buyer to finance a transaction. Representatives of Sheppard Mullin then reviewed with the board the latest draft merger agreement, highlighting key terms, the status of the negotiations, including a comparison of the special committee’s position to the terms agreed to or in the case of open items, Parent’s position as compared to the special committee’s position. The board provided Sheppard Mullin with input on the open issues and asked Sheppard Mullin to revise the merger agreement in accordance with its directive.

On August 11, 2013, Parent indicated to Houlihan Lokey its preliminary proposal to raise its bid to $22.04 per share. Over the course of the day, Houlihan Lokey (with input from the special committee) and Parent engaged in discussions regarding the amount per share to be paid by Parent. The special committee directed Houlihan Lokey to request that Parent increase the proposed merger consideration to $23.00 per share, and this request was relayed in accordance with the special committee’s directives.

On August 12, 2013, Parent informed Houlihan Lokey that it had received authorization to increase its proposed merger consideration to $23.00 per share, subject to reaching agreement on final terms in the draft

34

merger agreement. On August 12, 2013, the special committee met with representatives of Sheppard Mullin to review the latest draft merger agreement. Sheppard Mullin informed the special committee that agreement had been reached on all key terms in the draft merger agreement other than the amount of the termination fees. Sheppard Mullin reviewed with the special committee each party’s position with respect to the amount of termination fees and received guidance from the special committee on how to reach resolution on this open point.

After several further discussions and negotiations, on August 14, 2013, representatives of Sheppard Mullin and Gibson Dunn confirmed agreement on the termination fees. The parties agreed that the termination fee would be $11.0 million or approximately 4% of equity value, and the reverse termination fee would be $19.0 million, or approximately 7% of equity value. Sheppard Mullin thereafter provided the board with an updated draft of the merger agreement, reflecting the agreed-to termination fees, together with a summary of key deal terms and the resolution agreed to on each such term as well as drafts of the equity commitment letter, debt commitment letter and limited guaranty.

As a condition to signing the merger agreement, Parent required the directors and executive officers of NTS to sign a voting agreement agreeing, among other things, for so long as the merger agreement is in effect, to vote their shares in favor of the merger, vote against any alternative transaction, and vote against any other actions that would reasonably be expected to adversely affect or delay merger. The voting agreement also provides Parent with an irrevocable proxy to vote the shares of those individuals that executed a voting agreement. Per Sheppard Mullin’s request, the voting agreement terminates upon the termination of the merger agreement. On August 14, 2013, Sheppard Mullin sent a draft of the voting agreement to all directors and executive officers of NTS, except for Mr. Jacobs who had not been part of the discussions concerning the potential transaction.

Separately, on August 14, 2013, Sheppard Mullin telephoned Mr. Jacobs, stating that the Company was close to reaching an agreement on a transaction and that the buyer had requested Mill Road’s execution of a voting agreement and an amendment to its warrant agreement in connection with the transaction to clarify that the warrant would automatically exercise and terminate upon an acquisition of the Company. On August 15, 2013, Mill Road executed the warrant amendment, but declined to enter the voting agreement without additional negotiation of its terms.

On August 15, 2013, the special committee met telephonically to review the final terms of the draft merger agreement. Representatives of Sheppard Mullin and Houlihan Lokey attended the meeting. The representatives of Sheppard Mullin reviewed the draft merger agreement, including incorporation of the final terms on termination fees. They also reviewed the terms of the equity commitment letter, debt commitment letter and limited guaranty. At the same meeting, Houlihan Lokey reviewed with the special committee Houlihan Lokey’s financial analysis of the $23.00 per share consideration to be received by holders of NTS common stock in the proposed merger and rendered an oral opinion to the special committee, which was confirmed in writing by delivery of Houlihan Lokey’s written opinion dated August 15, 2013, to the effect that, as of such date and based upon and subject to the procedures followed, assumptions made, qualifications and limitations on the review undertaken and other matters considered by Houlihan Lokey in preparing its opinion, the $23.00 per share consideration to be received by the holders of NTS common stock in the merger pursuant to the merger agreement was fair, from a financial point of view, to those holders.

The special committee, in consultation with Houlihan Lokey, also considered whether any of the other bidders was likely to deliver a superior bid. The special committee took note of the fact that the five remaining bidders were all financial buyers. Given that financial buyers are generally constrained in bidding by leverage capacity and the desire to exceed a threshold internal rate of return on capital, the special committee believed that none of the remaining bidders were likely to offer a premium to Parent’s proposed merger consideration of $23.00 per share. The special committee also considered the risk of continuing the process, including the risks that Parent would withdraw its bid, of execution in the business, of a change in debt capital markets, and of changes in customer demand, any of which could have a material impact on the Company’s business and the price per share in any sale. Following this analysis, the special committee unanimously determined to recommend that the board of directors approve the merger agreement and the merger.

35

On the evening of August 15, 2013, the board of directors met telephonically. Also participating were representatives of Sheppard Mullin and Houlihan Lokey. The representatives of Sheppard Mullin reviewed the terms of the draft of the merger agreement and described changes to such agreement since the last meeting of the board of directors, including final resolution of deal terms on the conditions to closing, fiduciary out, termination rights and termination fees. They also reviewed the terms of the equity commitment letter, debt commitment letter and limited guaranty that had been negotiated in connection with the proposed transaction. At the same meeting, Houlihan Lokey reviewed with the board of directors the financial analysis of the $23.00 per share consideration that it had reviewed with the special committee and informed the board that its opinion to the special committee had been rendered. The board also discussed, in consultation with Houlihan Lokey, the status of the other bidders and the special committee’s analysis that the other bidders were unlikely to produce a bid at a premium to Parent’s, as well as the risks involved in deferring acceptance of Parent’s offer.

After discussing each of the above matters in full and considering each of the factors set forth below in “The Merger — Reasons for the Merger,” the NTS board of directors unanimously determined that the merger agreement, and the merger are fair to and in the best interests of NTS and its shareholders, approved the merger and merger agreement and recommended that NTS’s shareholders vote to approve the merger agreement at any meeting of shareholders of NTS to be called for the purposes of acting thereon.

After the board’s meeting on August 15, 2013, Parent finalized the debt commitment letter with its lenders and the parties finalized the merger agreement, the equity commitment letter and the limited guaranty. Late in the evening, the parties executed those agreements in connection with the transaction.

On August 16, 2013, prior to the opening of trading of NTS common stock on the NASDAQ Global Market, NTS issued a press release announcing the execution of the merger agreement and filed a Current Report on Form 8-K with the SEC reporting on the entry into the merger agreement.

Reasons for the Merger

The NTS board of directors consulted with management, the special committee and the special committee’s legal and financial advisors in connection with its evaluation of the merger agreement and the merger. In reaching its decision to unanimously approve the merger, and to unanimously recommend that NTS’s shareholders vote to approve the merger agreement and the transactions contemplated thereby, including the merger, the board of directors considered the following factors and potential benefits of the merger, each of which it believes supported its decision:

1. Strategic Alternatives. The board of directors considered strategic alternatives to increase shareholder value other than a sale of NTS, including (i) continued execution of its organic growth strategy and acquisition strategy and (ii) a secondary offering of common stock to raise growth capital and increase the public float and shareholder liquidity, and concluded that the merger is more favorable to NTS’s shareholders than such strategic alternatives.

2. Shareholder Monetization of Investment. The board of directors considered that the merger allows NTS’s shareholders to monetize their investment in the Company in the near future, providing shareholders with the value certainty and liquidity of cash, while avoiding risks and uncertainties, including those relating to the following: risks related to the Company’s business including its ability to meet its operating goals; economic risks including changes that would impact demand for the Company’s services in key industries such as aerospace and defense; competitive risks; changes in interest rates and capital markets risks that may impact the Company’s cost of capital or the price at which its common stock trades; and market risks related to the Company’s limited float and the impact on the trading price and liquidity in the Company’s common stock.

3. Consideration to Be Paid and Capital Structure. The board of directors considered that the consideration to be paid in the merger is all cash, and includes payment for all outstanding common stock, stock options, warrants and phantom stock appreciation rights.

36

4. Unlikelihood of a Superior Offer to Parent’s. The belief of the board of directors, after consideration in consultation with management and its advisors, that continuing discussions with other bidders, or soliciting interest from additional third parties, would be unlikely to lead to an equivalent or better offer and that deferring acceptance of Parent’s proposed offer could lead to the loss of such offer.

5. Market Price of NTS’s Common Stock. The board of directors considered the current and historical market prices of NTS common stock, and the fact that the per share merger consideration represents a premium to the market price of NTS common stock, including a premium of approximately 38.7% over the closing price on August 15, 2013, the last full trading day prior to the public announcement of the merger agreement, a premium of 40.7% over the average closing price for the one-week period ended August 15, 2013, a premium of 42.4% over the one-month average closing price for the period ended August 15, 2013, and a premium of 133.2% over the one-year average closing price for the period ended August 15, 2013. The board of directors further considered that, if NTS were to remain an independent, publicly traded company, the potential effects of our strategic growth plan and current capital market conditions would make it difficult for NTS common stock to achieve the price provided for in the merger agreement in the foreseeable future.

6. Opinion of Financial Advisor to the Special Committee. The board of directors considered the financial analysis reviewed by Houlihan Lokey with the special committee, and the oral opinion provided to the NTS special committee (which was confirmed in writing by delivery of Houlihan Lokey’s written opinion dated August 15, 2013) to the effect that, as of such date and based upon and subject to the procedures followed, assumptions made, qualifications and limitations on the review undertaken and other matters considered by Houlihan Lokey in preparing its opinion, the $23.00 per share consideration to be received by the holders of NTS common stock in the merger pursuant to the merger agreement was fair, from a financial point of view, to those holders. See “The Merger—Opinion of Financial Advisor to the Special Committee” on page 39.

7. Widely Marketed Auction Process. The special committee had engaged in a broad market solicitation, including contacts by the special committee’s financial advisor at the instruction of the special committee with 194 prospective bidders, consisting of 53 strategic buyers and 141 financial buyers, distribution of the “teaser” memorandum to 114 prospective bidders that expressed interest and confidentiality agreements were secured with 116 parties.

8. Likelihood the Merger Would Be Completed. The board of directors considered the likelihood that the merger would be completed, based on, among other things:

• the absence of a financing condition in the merger agreement, the fact that Parent had obtained committed debt and equity financing for the merger, the number and nature of the conditions to the debt and equity financing, the reputation of the financing sources and obligation of Parent to use its reasonable best efforts to obtain debt financing;

• the absence of significant required regulatory approvals;

• that the merger agreement provides that, in the event of a failure of the merger to be consummated under certain circumstances, Parent will pay NTS a $19.0 million “reverse” termination fee, without NTS having to establish any damages; and

• the reputation and financial capacity of Aurora Capital Group.

9. Ability to Consider and Enter into an Agreement with Respect to a Superior Proposal. The merger agreement provides:

• NTS with the ability, under certain circumstances, to provide information to third parties regarding unsolicited acquisition proposals, if the board of directors has determined, among other things, in good faith following procedures specified in the merger agreement that the failure to take such action would be inconsistent with its fiduciary duties under applicable law;

37

• the board of directors with the ability to terminate the merger agreement to enter into a superior proposal, subject to certain conditions, including simultaneous payment of a $11.0 million termination fee; and

• the ability of the board of directors under certain circumstances, following procedures specified in the merger agreement, to withdraw, qualify or modify its recommendation that NTS’s shareholders vote to approve the merger agreement and merger.

10. Availability of Statutory Dissenter Rights. The availability of dissenting shareholder rights under the California General Corporation Law to holders of NTS common stock who comply with all of the requirements and procedures under the California General Corporation Law, which allows such holders to seek appraisal of the fair market value of their shares of NTS common stock as determined in California Superior Court.

11. Termination Date. The fact that the termination date under the merger agreement allows for time that is expected to be sufficient to complete the merger agreement.

The board of directors also considered and balanced against the potential benefits of the transaction various risks and other potentially negative factors concerning the transaction, but determined that these factors were outweighed by the factors supporting the transaction. These risks included the following: the risk that the transaction will not close and the Company will have incurred substantial transaction related expenses; the risk that if the transaction closes the shareholders will not participate in future appreciation and would forego a possibly superior price if the Company’s performance exceeded expectations; and the fact that an all-cash transaction would be taxable to the Company’s shareholders that are U.S. holders for federal income tax purposes.

The foregoing includes the material factors considered by the board of directors. In view of its many considerations, the board of directors did not find it practical to, and did not, quantify or otherwise assign relative weights to the specific factors considered. In addition, individual members of the board of directors may have given different weights to the various factors considered.

After considering the factors discussed above, upon the unanimous recommendation of the special committee, the board of directors unanimously (i) determined that the terms of the merger agreement, the merger and the other transactions contemplated thereby are fair to and in the best interests of NTS shareholders, (ii) approved and declared advisable the merger agreement and the transactions contemplated thereby, including the merger, (iii) directed that the merger agreement be submitted to the shareholders of NTS for adoption and approval and (iv) recommended that NTS’s shareholders vote in favor of the adoption and approval of the merger agreement and the transactions contemplated thereby, including the merger. NTS’s board of directors is comprised of nine directors, six of whom are independent.

Recommendation of the NTS Board of Directors

The NTS board of directors, in accordance with and upon the unanimous recommendation of a special committee of independent directors, has unanimously approved, and declared to be in the best interests of NTS and its shareholders the merger agreement and the transactions contemplated thereby, including the merger. The NTS board of directors unanimously recommends that NTS shareholders vote “FOR” the merger agreement proposal, “FOR” the advisory (non-binding) proposal to approve specified compensation that may become payable to the named executive officers of NTS in connection with the merger, and “FOR” the proposal to adjourn the special meeting to solicit additional proxies, if necessary or appropriate.

When you consider the recommendation of the NTS board of directors, you should be aware that the Company’s directors and executive officers may have interests that are different from, or in addition to, the interests of the Company’s shareholders generally. See “The Merger — Interests of NTS Executive Officers and

38

Directors in the Merger.” The board of directors was aware of and considered these interests in evaluating and negotiating the merger agreement, and in unanimously recommending that the merger agreement be approved by the shareholders of the Company.

Opinion of Financial Advisor to the Special Committee.

On August 15, 2013, Houlihan Lokey rendered an oral opinion to the special committee (which was confirmed in writing by delivery of Houlihan Lokey’s written opinion dated August 15, 2013) as to, as of August 15, 2013, the fairness, from a financial point of view, of the $23.00 per share consideration to be received by the holders of NTS common stock in the merger pursuant to the merger agreement.

Houlihan Lokey’s opinion was directed to the special committee and only addressed the fairness from a financial point of view of the $23.00 per share consideration to be received by the holders of NTS common stock in the merger pursuant to the merger agreement and does not address any other aspect or implication of the merger. The summary of Houlihan Lokey’s opinion in this proxy statement is qualified in its entirety by reference to the full text of its written opinion, which is attached as Annex B to this proxy statement and sets forth the procedures followed, assumptions made, qualifications and limitations on the review undertaken and other matters considered by Houlihan Lokey in preparing its opinion. However, neither Houlihan Lokey’s opinion nor the summary of its opinion and the related analyses set forth in this proxy statement are intended to be, and do not constitute, advice or a recommendation to the special committee, the board of directors, NTS or any shareholder as to how to act or vote with respect to the merger or related matters.

In arriving at its opinion, Houlihan Lokey, among other things:

1. reviewed an execution version of the merger agreement;

2. reviewed certain publicly available business and financial information relating to NTS that Houlihan Lokey deemed to be relevant;

3. reviewed certain information relating to the historical, current and future operations, financial condition and prospects of NTS made available to Houlihan Lokey by NTS, including financial projections (and adjustments thereto) prepared by NTS management relating to NTS for the fiscal years ending 2014 through 2018;

4. spoke with certain members of NTS management and certain representatives and advisors of NTS regarding the business, operations, financial condition and prospects of NTS, the merger and related matters;

5. compared the financial and operating performance of NTS with that of other public companies that Houlihan Lokey deemed to be relevant;

6. considered publicly available financial terms of certain transactions that Houlihan Lokey deemed to be relevant;

7. reviewed the current and historical market prices and trading volume for NTS common stock, and the current and historical market prices of the publicly traded securities of certain other companies that Houlihan Lokey deemed to be relevant;

8. considered the third-party solicitation process conducted by the special committee, with Houlihan Lokey’s assistance, with respect to a possible sale of NTS, including the special committee’s authorization of negotiations with Parent leading to the merger while such process was otherwise at a less advanced stage with other potential buyers; and

9. conducted such other financial studies, analyses and inquiries and considered such other information and factors as Houlihan Lokey deemed appropriate.

39

Houlihan Lokey relied upon and assumed, without independent verification, the accuracy and completeness of all data, material and other information furnished, or otherwise made available, to it, discussed with or reviewed by it, or publicly available, and did not assume any responsibility with respect to such data, material and other information. In addition, NTS management advised Houlihan Lokey, and Houlihan Lokey assumed, that the financial projections (and adjustments thereto) reviewed by Houlihan Lokey were reasonably prepared in good faith on bases reflecting the best currently available estimates and judgments of management as to the future financial results and condition of NTS, and Houlihan Lokey expressed no opinion with respect to such projections or the assumptions on which they were based. Houlihan Lokey relied upon and assumed, without independent verification, that there had been no change in the business, assets, liabilities, financial condition, results of operations, cash flows or prospects of NTS since the respective dates of the most recent financial statements and other information, financial or otherwise, provided to Houlihan Lokey that would have been material to its analyses or opinion, and that there was no information or any facts that would have made any of the information reviewed by Houlihan Lokey incomplete or misleading. In addition, Houlihan Lokey relied upon, without independent verification, the assessments of NTS management as to defense spending and other industry trends and prospects and the potential impact thereof on NTS, and Houlihan Lokey assumed, at the direction of NTS, that there would be no developments with respect to any such matters that would affect Houlihan Lokey’s analyses or opinion.

Houlihan Lokey relied upon and assumed, without independent verification, that (a) the representations and warranties of all parties to the merger agreement and all other related documents and instruments that are referred to therein were true and correct, (b) each party to the merger agreement and such other related documents and instruments would fully and timely perform all of the covenants and agreements required to be performed by such party, (c) all conditions to the consummation of the merger would be satisfied without waiver thereof, and (d) the merger would be consummated in a timely manner in accordance with the terms described in the merger agreement and such other related documents and instruments, without any amendments or modifications thereto. Houlihan Lokey relied upon and assumed, without independent verification, that (i) the merger would be consummated in a manner that complies in all respects with all applicable federal and state statutes, rules and regulations, and (ii) all governmental, regulatory, and other consents and approvals necessary for the consummation of the merger would be obtained and that no delay, limitations, restrictions or conditions would be imposed or amendments, modifications or waivers made that would have an effect on the merger or NTS that would be material to Houlihan Lokey’s analyses or opinion. In addition, Houlihan Lokey relied upon and assumed, without independent verification, that the merger agreement, when executed, would not differ in any respect from the execution version of the merger agreement identified above.

Furthermore, in connection with its opinion, Houlihan Lokey was not requested to make, and did not make, any physical inspection or independent appraisal or evaluation of any of the assets, properties or liabilities (fixed, contingent, derivative, off-balance-sheet or otherwise) of NTS or any other party, nor was Houlihan Lokey provided with any such appraisal or evaluation. With respect to NTS’s unused land in Santa Clarita, California, or the “Santa Clarita Property,” Houlihan Lokey relied upon, without independent verification, the proposed purchase price offered in a non-binding letter of intent received by NTS from a third party for purposes of Houlihan Lokey’s analyses or opinion. Houlihan Lokey did not estimate, and expressed no opinion regarding, the liquidation value of any entity or business. Houlihan Lokey undertook no independent analysis of any potential or actual litigation, regulatory action, possible unasserted claims or other contingent liabilities, to which NTS was or may have been a party or was or may have been subject, or of any governmental investigation of any possible unasserted claims or other contingent liabilities to which NTS was or may have been a party or was or may have been subject.

Houlihan Lokey’s opinion was necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to Houlihan Lokey as of, the date of the opinion. Houlihan Lokey did not undertake, and is under no obligation, to update, revise, reaffirm or withdraw its opinion, or otherwise comment on or consider events occurring or coming to Houlihan Lokey’s attention after the date of the opinion. Houlihan Lokey did not express any opinion as to the price or range of prices at which shares of NTS common stock may be purchased or sold, or otherwise be transferable, at any time.

40

Houlihan Lokey’s opinion was furnished for the use of the special committee (in its capacity as such) and, at the special committee’s request, the board of directors (in its capacity as such) in connection with their evaluation of the merger and may not be used for any other purpose without Houlihan Lokey’s prior written consent. Houlihan Lokey’s opinion should not be construed as creating any fiduciary duty on Houlihan Lokey’s part to any party. Houlihan Lokey’s opinion is not intended to be, and does not constitute, a recommendation to the special committee, the board of directors, NTS, any securityholder or any other party as to how to act or vote with respect to any matter relating to the merger or otherwise.

Houlihan Lokey was not requested to opine as to, and its opinion did not express an opinion as to or otherwise address, among other things: (i) the underlying business decision of the special committee, the board of directors, NTS, its securityholders or any other party to proceed with or effect the merger, (ii) the terms of any arrangements, understandings, agreements or documents related to, or the form, structure or any other portion or aspect of, the merger or otherwise (other than the $23.00 per share merger consideration to the extent expressly specified in the opinion), (iii) the fairness of any portion or aspect of the merger to the holders of any class of securities, creditors or other constituencies of NTS, or to any other party, except if and only to the extent expressly set forth in the last sentence of Houlihan Lokey’s opinion, (iv) the relative merits of the merger as compared to any alternative business strategies or transactions that might have been available for NTS or any other party, (v) the fairness of any portion or aspect of the merger to any one class or group of NTS’s or any other party’s securityholders or other constituents vis-à-vis any other class or group of NTS’s or such other party’s securityholders or other constituents (including, without limitation, the allocation of any consideration amongst or within such classes or groups of securityholders or other constituents), (vi) whether or not NTS, its securityholders, Parent or any other party is receiving or paying reasonably equivalent value in the merger, (vii) the solvency, creditworthiness or fair value of NTS, Parent or any other participant in the merger, or any of their respective assets, under any applicable laws relating to bankruptcy, insolvency, fraudulent conveyance or similar matters, or (viii) the fairness, financial or otherwise, of the amount, nature or any other aspect of any compensation to or consideration payable to or received by any officers, directors or employees of any party to the merger, any class of such persons or any other party, relative to the per share merger consideration or otherwise. Furthermore, no opinion, counsel or interpretation was intended in matters that require legal, regulatory, accounting, insurance, tax or other similar professional advice. Houlihan Lokey assumed that such opinions, counsel or interpretations had been or would be obtained from appropriate professional sources. Furthermore, Houlihan Lokey relied, with the consent of the special committee, on the assessments by the special committee, the board of directors, NTS and their respective advisors as to all legal, regulatory, accounting, insurance and tax matters with respect to NTS, the merger or otherwise.

In preparing its opinion to the special committee, Houlihan Lokey performed a variety of analyses, including those described below. The summary of Houlihan Lokey’s analyses described below is not a complete description of the analyses underlying Houlihan Lokey’s opinion. The preparation of such opinions is a complex process involving various quantitative and qualitative judgments and determinations with respect to the financial, comparative and other analytical methods employed and the adaptation and application of these methods to the unique facts and circumstances presented. As a consequence, neither Houlihan Lokey’s opinion nor its underlying analyses is readily susceptible to summary description. Houlihan Lokey arrived at its opinion based on the results of all analyses undertaken by it and assessed as a whole and did not draw, in isolation, conclusions from or with regard to any individual analysis, methodology or factor. Accordingly, Houlihan Lokey believes that its analyses and the following summary must be considered as a whole and that selecting portions of its analyses, methodologies and factors, without considering all analyses, methodologies and factors or the narrative description of the analyses, could create a misleading or incomplete view of the processes underlying Houlihan Lokey’s analyses and opinion.

In performing its analyses, Houlihan Lokey considered general business, economic, industry and market conditions, financial and otherwise, and other matters as they existed on, and could be evaluated as of, the date of the opinion. Houlihan Lokey’s analyses involved judgments and assumptions with regard to industry performance, general business, economic, regulatory, market and financial conditions and other matters, many of

41

which are beyond the control of NTS. No company, transaction or business used in Houlihan Lokey’s analyses for comparative purposes is identical to NTS or the proposed merger and an evaluation of the results of those analyses is not entirely mathematical. The estimates contained in the financial projections for NTS provided by NTS management and the implied reference range values indicated by Houlihan Lokey’s financial analyses are not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than those suggested by the analyses. In addition, such analyses do not purport to be appraisals or to reflect the prices at which businesses or securities actually may be sold, which may depend on a variety of factors, many of which are beyond the control of NTS. Much of the information used in, and accordingly the results of, Houlihan Lokey’s analyses are inherently subject to substantial uncertainty.

Houlihan Lokey’s opinion was only one of many factors considered by the special committee and the board of directors in evaluating the proposed merger. Neither Houlihan Lokey’s opinion nor its analyses were determinative of the per share merger consideration or of the views of the special committee, the board or NTS management with respect to the merger or the per share merger consideration. The type and amount of consideration payable in the merger were determined through negotiation between NTS and Parent, and the decision to enter into the merger agreement was solely that of the board or directors.

The following is a summary of the material financial analyses reviewed by Houlihan Lokey with the special committee and, at the special committee’s request, the board of directors relating to Houlihan Lokey’s opinion rendered on August 15, 2013. The order of the financial analyses summarized below does not represent relative importance or weight given to those analyses by Houlihan Lokey. The analyses summarized below include information presented in tabular format. The tables alone do not constitute a complete description of the analyses. Considering the data in the tables below without considering the full narrative description of the analyses, as well as the methodologies underlying and the assumptions, qualifications and limitations affecting each analysis, could create an incomplete view of Houlihan Lokey’s analyses.

For purposes of its analyses, Houlihan Lokey reviewed a number of financial metrics, including:

• enterprise value — the value of the relevant company’s outstanding equity securities (taking into account its outstanding options, warrants and other convertible securities) based on the relevant company’s closing stock price, plus net debt (calculated as outstanding indebtedness and preferred stock less the amount of cash and cash equivalents on its balance sheet), as of a specified date.

• transaction value — the implied enterprise value of the relevant target company based on the announced transaction equity price and other public information available at the time of the announcement.

• adjusted EBITDA — the amount of the relevant company’s earnings before interest, taxes, depreciation and amortization, adjusted for certain non-recurring items.

Implied reference range values indicated by Houlihan Lokey’s financial analyses reflect, among other things, reductions for estimated liabilities per NTS management relating to obligations under NTS’s Long Term Incentive Plan and Supplemental Executive Retirement Plan in the event of a change of control transaction and earnout and holdback obligations from NTS’s prior acquisitions of Lightning Technologies, Inc. and Garwood Laboratories, Inc. In addition, an assumed value for the Santa Clarita Property was utilized per NTS management based on the proposed purchase price offered in the non-binding letter of intent received by NTS from a third party, net of associated moving expenses and capital gains taxes as estimated by NTS management. The book value of Ascertiva Group Limited’s non-controlling interest in NQA, Inc. was not utilized given that cash flows attributable to that interest were deducted from the cash flows of NTS reflected in the financial projections provided by NTS management.

Selected Companies Analysis. Houlihan Lokey considered certain financial data for NTS and selected companies in the testing and certification industry with publicly traded equity securities that Houlihan Lokey

42

deemed relevant. Enterprise values derived from the selected companies analysis described below were calculated using the closing prices of the common stock of the selected companies listed below as of August 14, 2013. Accordingly, this information may not reflect current or future market conditions. Estimates of next fiscal year, or NFY, adjusted EBITDA for the selected companies listed below were based on publicly available research analyst estimates for the selected companies and were calendarized to reflect a December year end where appropriate.

The financial data reviewed included:

• enterprise value as a multiple of latest 12 months, or LTM, adjusted EBITDA; and

• enterprise value as a multiple of estimated NFY adjusted EBITDA.

The selected companies and resulting low, high, median and mean data for the selected companies were:

• ALS Limited

• Bureau Veritas SA

• Eurofins Scientific SA

• Exponent Inc.

• Intertek Group plc

• Mistras Group, Inc.

• SGS SA

• Team, Inc.

	Enterprise Value/ LTM Adjusted EBITDA		Enterprise Value/ NFY Adjusted EBITDA
Low		8.9x		8.2x
High		17.6x		14.4x
Median		13.6x		13.1x
Mean		13.0x		12.1x

Taking into account the results of the selected companies analysis, Houlihan Lokey applied multiple ranges of 10.0x to 11.0x LTM adjusted EBITDA and 9.5x to 10.5x NFY adjusted EBITDA, respectively, to NTS’s LTM ended April 30, 2013 adjusted EBITDA and estimated fiscal year ending January 31, 2014 adjusted EBITDA based on the financial projections for NTS provided by NTS management. The selected companies analysis indicated implied per share reference ranges for NTS of $17.76 to $19.95 based on the selected range of LTM adjusted EBITDA multiples and $17.24 to $19.49 based on the selected range of NFY adjusted EBITDA multiples, as compared to the $23.00 per share merger consideration.

Selected Transactions Analysis

Houlihan Lokey considered certain financial data for selected publicly-announced transactions in the testing and certification industry that Houlihan Lokey deemed relevant. Generally, transaction values for the target companies derived from the selected transactions analysis described below were calculated as of the public announcement date of the relevant transaction based on the estimated purchase prices paid in the selected transactions. Accordingly, this information may not reflect current or future market conditions.

43

The financial data reviewed included, among other things, enterprise value as a multiple of, to the extent publicly available, LTM adjusted EBITDA. The selected transactions and resulting low, high, median and mean data for the selected transactions were:

Mean		10.0x

(1) Excluded from low, high, median and mean data. LTM adjusted EBITDA for target company was not publicly available.

Taking into account the results of the selected transactions analysis, Houlihan Lokey applied multiple ranges of 10.0x to 11.0x LTM adjusted EBITDA to LTM ended April 30, 2013 adjusted EBITDA for NTS. The selected transactions analysis indicated an implied per share reference range for NTS of $17.76 to $19.95, as compared to the $23.00 per share merger consideration.

Discounted Cash Flow Analysis. Houlihan Lokey performed a discounted cash flow analysis of NTS by calculating the estimated net present value of the unlevered, after-tax free cash flows that NTS was forecasted to generate through January 31, 2018 based on the financial projections for NTS provided by NTS management. Houlihan Lokey calculated terminal values for NTS by applying a range of perpetuity growth rates of 3.5% to 4.5% to NTS’s estimated fiscal year ending 2018 unlevered free cash flow, adjusted to normalize certain items. The present values of the cash flows and terminal values were then calculated using discount rates ranging from 12.5% to 14.0%. The discounted cash flow analysis indicated an implied per share reference range for NTS of $14.10 to $19.31, as compared to the $23.00 per share merger consideration.

44

Other Matters

Houlihan Lokey was engaged by the special committee to act as its financial advisor in connection with the merger and provide financial advisory services, including an opinion to the special committee (in its capacity as such) regarding the fairness, from a financial point of view, of the consideration to be received by the holders of NTS common stock in the merger pursuant to the merger agreement. The special committee engaged Houlihan Lokey based on Houlihan Lokey’s experience and reputation. Houlihan Lokey is regularly engaged to provide advisory services in connection with mergers and acquisitions, financings, and financial restructurings. Houlihan Lokey is entitled to a fee of approximately $7.6 million for its services, a portion of which became payable upon the execution of Houlihan Lokey’s engagement letter, a portion of which became payable upon the delivery of Houlihan Lokey’s opinion, regardless of the conclusion reached therein, and approximately $7.1 million of which is contingent upon the consummation of the merger. NTS has also agreed to reimburse Houlihan Lokey for certain expenses and to indemnify Houlihan Lokey, its affiliates and certain related parties against certain potential liabilities and expenses, including certain liabilities under the federal securities laws arising out of or relating to Houlihan Lokey’s engagement.

In the ordinary course of business, certain of Houlihan Lokey’s employees and affiliates, as well as investment funds in which they may have financial interests or with which they may co-invest, may acquire, hold or sell, long or short positions, or trade, in debt, equity, and other securities and financial instruments (including loans and other obligations) of, or investments in, NTS, one or more affiliates of Aurora Capital Group, or any other party that may be involved in the merger and their respective affiliates or any currency or commodity that may be involved in the merger.

An affiliate of Houlihan Lokey has in the past provided certain financial advisory services to an affiliate of Aurora Capital Group, for which such affiliate of Houlihan Lokey received and is entitled to receive compensation. Houlihan Lokey and certain of its affiliates may provide investment banking, financial advisory and other financial services to NTS, Parent, Aurora Capital Group or one or more securityholders, affiliates and/or portfolio companies of investment funds affiliated or associated with Aurora Capital Group, referred to collectively as “Aurora Entities,” other participants in the merger or certain of their respective affiliates or securityholders in the future, for which Houlihan Lokey and its affiliates may receive compensation. In addition, Houlihan Lokey and certain of its affiliates and certain of our and their respective employees may have committed to invest in private equity or other investment funds managed or advised by Aurora Capital Group, other participants in the merger or certain of their respective affiliates, and in portfolio companies of such funds, and may have co-invested with Aurora Entities, other participants in the merger or certain of their respective affiliates or securityholders, and may do so in the future. Furthermore, in connection with bankruptcies, restructurings, and similar matters, Houlihan Lokey and certain of its affiliates may have in the past acted, may currently be acting and may in the future act as financial advisor to debtors, creditors, equity holders, trustees, agents and other interested parties (including, without limitation, formal and informal committees or groups of creditors) that may have included or represented and may include or represent, directly or indirectly, or may be or have been adverse to, NTS, Parent, the Aurora Entities, other participants in the merger or certain of their respective affiliates or securityholders, for which advice and services Houlihan Lokey and its affiliates have received and may receive compensation.

Certain Financial Information

In the course of the discussions described under “—Background of the Merger,” the Company provided Parent and certain other potential purchasers that signed confidentiality agreements selected, non-public financial projections for fiscal years 2014 through 2018 prepared by our senior management. Such projections were also provided to the board of directors, the NTS special committee and its financial advisor, Houlihan Lokey, in connection with the board’s and the special committee’s respective consideration of the merger. We have included a summary of these projections below to give our shareholders access to certain nonpublic information provided to Parent, the board of directors, the NTS special committee and its financial advisor. NTS does not as a

45

matter of course make public projections as to future performance or earnings. These financial projections constitute forward-looking statements. See “Forward-Looking Statements.”

NTS advised the recipients of the financial projections that such projections are subjective in many respects. The financial projections are based on a variety of estimates and assumptions made by our senior management regarding the Company’s business, industry performance, general business, economic, market and financial conditions and other matters, many of which are difficult to predict and are beyond the Company’s control. In addition, the financial projections included the assumption that NTS would be able to secure substantial additional capital in order to finance its projected growth, though there are no agreements or arrangements in place to provide such capital at this time. In recognition of such limitations, NTS believes Parent and the other potential purchasers applied their own independent judgment to the projections and formulated a valuation for the Company based on their independent investigation of the Company’s historical performance and their views and assumptions as to the Company’s future prospects.

The financial projections were prepared by NTS’s senior management in good faith and on a reasonable basis based on the best information available to our management at the time of their preparation. The financial projections, however, are not actual results and should not be relied upon as being necessarily indicative of actual future results, and readers of this proxy statement are cautioned not to place undue reliance on this information. Neither NTS’s independent auditors, nor any other independent accountants, have compiled, examined or performed any procedures with respect to the financial projections set forth below, nor have they expressed any opinion or any other form of assurance with respect thereto. The financial projections were not prepared with a view toward public disclosure or compliance with generally accepted accounting principles in the United States (“GAAP”), the published guidelines of the SEC regarding projections or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information. Except as required by law, NTS does not intend to update these financial projections or to make other projections public in the future.

In addition, because the financial projections cover multiple years, such information by its nature becomes less predictive with each successive year and becomes subject to increasing uncertainty in the years beyond 2014. While presented with numeric specificity, the assumptions upon which the financial projections were based necessarily involve judgments with respect to, among other things, future economic and competitive conditions, many of which are difficult to predict accurately and are beyond the control of NTS’s senior management. See the risk factors included in our most recent filings on Form 10-Q and Form 10-K. Also, the economic and business environment can and do change quickly, which add a significant level of unpredictability and execution risk. It is expected that differences between actual and projected results will occur, and actual results may be materially greater or less than those contained in the projections. If the merger is not consummated, the Company may not be able to achieve these financial projections. There can be no assurance that the projections, or the assumptions underlying the projections, will be realized. Accordingly, readers of this proxy statement are cautioned not to place undue reliance on the financial projections included in this proxy statement.

The financial projections included the following : (i) net revenues of $184.9 million, $197.9 million, $212.8 million, $231.4 million, and $254.1 million for fiscal years 2014, 2015, 2016, 2017 and 2018, respectively; (ii) gross profit of $53.0 million, $60.8 million, $68.2 million, $79.0 million, and $92.8 million for fiscal years 2014, 2015, 2016, 2017 and 2018, respectively; (iii) operating income of $14.9 million, $27.2 million, $32.8 million, $41.6 million and $52.9 million for fiscal years 2014, 2015, 2016, 2017 and 2018, respectively; (iv) EBITDA of $25.7 million, $38.8 million, $45.2 million, $55.0 million, and $67.6 million for fiscal years 2014, 2015, 2016, 2017 and 2018; and (iv) Adjusted EBITDA of $31.0 million, $36.6 million, $42.7 million, $52.0 million and $64.1 million for fiscal years 2014, 2015, 2016, 2017, and 2018, respectively.

EBITDA and Adjusted EBITDA are considered non-GAAP financial measures. The Company provided this information to Parent and certain other potential purchasers because it believed it could be useful to potential bidders in evaluating, on a prospective basis, the Company’s operating performance. Non-GAAP financial

46

measures should not be considered in isolation from, or as a substitute for, financial information presented in compliance with GAAP, and non-GAAP financial measures as used in the projections may not be comparable to similarly titled amounts used by other companies. EBITDA is calculated as net income (earnings), plus interest, taxes, depreciation and amortization.

Adjusted EBITDA described above included, among other things, addbacks of amounts for public company costs, the Company’s Supplemental Executive Retirement Plan and stock-based compensation. The addbacks relating to public company costs, the Company’s Supplemental Executive Retirement Plan and stock-based compensation were not included in the financial projections provided to Houlihan Lokey by the Company for purposes of the financial analysis performed in connection with Houlihan Lokey’s opinion to the NTS special committee, which financial projections included (i) Adjusted EBITDA of $27.5 million, $33.0 million, $38.9 million, $48.2 million and $60.2 million for fiscal years 2014, 2015, 2016, 2017, and 2018, respectively; and (ii) unlevered free cash flows of $8.9 million, $16.7 million, $16.4 million, $22.1 million and $27.8 million for the remainder of fiscal 2014 and for fiscal years 2015, 2016, 2017 and 2018, respectively.

You should not regard the inclusion of these projections in this proxy statement as an indication that NTS, Parent or any of their respective affiliates, advisors or other representatives considered or consider the projections to be necessarily predictive of actual future events. None of NTS, Parent or any of their respective affiliates, advisors or other representatives has made or makes any representations regarding the ultimate performance of NTS compared to the information contained in the projections. NTS made no representation to Parent in the merger agreement or otherwise, concerning the financial projections.

Financing of the Merger

The Company and Parent estimate that the total amount of funds necessary to consummate the merger is approximately $352.7, including amounts required to: (i) make payments under the merger agreement to NTS shareholders and to holders of outstanding NTS options, warrants and stock appreciation rights, (ii) repay at the closing of the merger certain indebtedness of NTS and its subsidiaries; and (iii) pay certain fees, costs and expenses associated with closing the merger and the debt facilities. Parent expects this amount to be funded by a combination of equity and debt financing arranged by Parent. Parent has obtained equity and debt financing commitments described below in connection with the merger.

There are no conditions precedent or contingencies, whether oral or written, related to the funding of the full amount of the equity and debt financings, other than as expressly set forth in the equity and debt financing commitment letters.

Equity Financing

Parent has received an equity commitment letter, dated August 15, 2013, from Aurora Pacific Equity Partners, Inc., pursuant to which Aurora Pacific Equity Partners, Inc. committed to make, or cause its affiliates to make, an equity contribution of $177.0 million to Parent, the proceeds of which will be used as a source of funds required to fund the merger consideration and to pay related fees and expenses.

The obligation to fund all or any part of the equity contribution pursuant to the equity commitment letter is conditioned upon (i) the satisfaction or waiver at the closing of the conditions to Parent’s and Merger Sub’s obligations to consummate the transactions contemplated by the merger agreement, (ii) the prior or substantially concurrent funding contemplated under the debt financing described below and (iii) the simultaneous occurrence of the closing in accordance with the terms of the merger agreement.

47

Debt Financing

Parent has received a debt commitment letter, dated as of August 15, 2013, referred to as the “debt commitment letter,” from GCI Capital Markets LLC, referred to as “Golub.” The debt commitment letter contemplates that Golub will provide $152.5 million first lien senior secured credit facilities and $55.0 million second lien senior secured credit facilities, referred to as the “debt facilities,” the proceeds of which will be used (i) to provide funds to consummate the merger, (ii) to repay at the closing of the merger certain indebtedness of NTS and its subsidiaries, (iii) to fund certain fees, costs and expenses associated with closing the merger and the debt facilities and (iv) to provide for working capital, capital expenditures and other corporate purposes following the merger.

The debt commitment letter will expire if either the closing of the debt facilities or the funding of the initial loans thereunder has not occurred on or before February 15, 2014.

The consummation of the debt financing is subject to the following conditions, among others:

• consummation of the merger (or shall be consummated concurrently with the making of the initial loans on the closing date of the merger) in accordance with the merger agreement, without amendment, update, modification or waiver of certain terms and provisions as described in the debt commitment letter;

• execution of financing documents related to the debt financing;

• receipt of all required security interests, perfected in favor of Golub;

• receipt by Parent of net cash proceeds (and contribution of such net cash proceeds to Merger Sub) of new cash equity capital contributions on terms reasonably acceptable to Golub in an amount that as of the closing date represents no less than 40% of the total cash capitalization as defined in the debt commitment letter;

• receipt of a closing date pro forma balance sheet of Parent, the Merger Sub and their respective subsidiaries;

• receipt of unaudited financial statements for NTS and its subsidiaries for the most recent month-end and to be more no more than 45 days prior to the closing date;

• satisfaction by Parent, Merger Sub and their respective subsidiaries (including NTS and its subsidiaries) of certain funded consolidated senior debt to EBITDA ratios on the closing date;

• since August 15, 2013, there shall not have occurred any event, change, circumstance, occurrence, effect or state of facts that, individually or in the aggregate, has had or would reasonably be expected to have a material adverse effect (as defined in the merger agreement);

• receipt of all material governmental, regulatory and shareholder consents and approvals (if any) (other than those of Golub or any lender described in the debt commitment letter) necessary to consummate the closing of the debt facilities and to make the initial loans under the debt facilities on the closing date;

• no pending or threatened litigation or other proceedings (private or governmental) with respect to the debt facilities that could reasonably be expected to materially and adversely affect any of the debt facilities, Golub or any lender described in the debt commitment letter.

• repayment of the indebtedness of NTS and its subsidiaries to the extent provided in the debt commitment letter, and the termination of related security interests;

• the accuracy of the representations and warranties contained in the financing document as of the closing date in accordance with the standard set forth in the debt commitment letter;

• there must be no default or event of default in existence at the closing date under the financing documents, or immediately after giving effect to the consummation of the transactions contemplated thereby and the funding of all of the loans;

• delivery of all OFAC, Patriot Act and other applicable anti-money laundering and “know your customer” rules and regulations regarding NTS, Parent and Merger Sub; and

48

• payment to Golub and each of the lenders of all invoiced fees, costs, expenses and other amounts payable on or prior to the closing date pursuant to the debt commitment letter and/or any and all applicable financing documents.

Pursuant to the merger agreement, as an alternative to the debt financing, Parent and Merger Sub may obtain substitute financing in the form of a single lien senior secured credit facility so long as the replacement of the debt financing with the substitute financing would not be adverse in any material respect to NTS, taking the debt financing and substitute financing as a whole. Parent and Merger Sub currently intend to utilize such substitute financing and expect it to be in the form of a $183.0 million senior secured credit facility, comprised of a (i) $143.0 million term loan, advanced in full on the closing date, (ii) a $30.0 million delayed draw term loan, and (iii)a $10.0 million revolving loan facility.

Limited Guaranty

Concurrently with the execution of the merger agreement, Aurora Equity Partners IV L.P. and Aurora Overseas Equity Partners IV L.P. (each, a “guarantor” and, collectively, the “guarantors”) entered into a Limited Guaranty with NTS pursuant to which, among other things, each such guarantor has unconditionally agreed to guarantee, on a several and not joint basis, subject to the terms and conditions set forth in the Limited Guaranty, the obligations of Parent to make any payments required to be made by Parent under the merger agreement (other than payment of the merger consideration), up to a maximum amount equal to the guarantors’ respective pro rata portions of the $19.0 million “reverse” termination fee described in “The Merger Agreement — Fees and Expenses.” The guarantors are affiliates of Aurora Capital Group.

Accounting Treatment

The merger will be accounted for as a “purchase transaction” for financial accounting purposes.

Material U.S. Federal Income Tax Consequences of the Merger

The following discussion describes certain United States federal income tax consequences to NTS’s shareholders who are U.S. Holders and non-U.S. Holders (each as defined below) as a result of the exchange of their shares of NTS’s common stock for cash pursuant to the merger agreement. This summary is not a complete analysis of all potential U.S. federal income tax consequences, nor does it address any tax consequences arising under any state, local or foreign tax laws or U.S. federal estate or gift tax laws. This summary is based upon the Internal Revenue Code of 1986, as amended (the “Code”), United States Treasury Regulations issued thereunder, IRS rulings and pronouncements, and judicial decisions, all as of the date hereof and all of which are subject to differing interpretations or change which could affect the tax consequences described in this proxy statement (possibly on a retroactive basis). This discussion is for general information only and does not address all of the aspects of United States federal income taxation that may be relevant to a particular shareholder or to shareholders subject to special rules (including, without limitation, financial institutions, brokers, dealers or traders in securities or commodities, traders who elect to apply a mark-to-market method of accounting, insurance companies, “S” corporations, partnerships or other pass-through entities, controlled foreign corporations, passive foreign investment companies, U.S. expatriates, tax-exempt organizations, tax-qualified retirement plans, persons who are subject to the alternative minimum tax, persons who hold shares of NTS’s common stock as a position in a “straddle” or as part of a “hedging,” “conversion” or “integrated” transaction or other risk reduction strategy, directors, employees, former employees or other persons who acquired shares of NTS’s common stock as compensation, including upon the exercise of employee stock options, U.S. Holders that have a functional currency other than the United States dollar, and dissenting shareholders who perfect their appraisal rights (to the extent available under California law)). This summary assumes that shareholders hold their shares of NTS’s common stock as “capital assets” within the meaning of Section 1221 of the Code (generally, property held for investment). No IRS ruling has been or will be sought regarding any matter

49

discussed herein, and there can be no assurance that the IRS will not challenge one or more of the tax consequences described herein.

As used herein, the term “U.S. Holder” means a beneficial owner of NTS’s common stock that for United States federal income tax purposes is:

• an individual who is a citizen or resident of the United States, including an alien individual who is a lawful permanent resident of the United States or meets the “substantial presence” test under Section 7701(b) of the Code;

• a corporation (or other entity taxable as a corporation for United States federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

• an estate, the income of which is subject to United States federal income taxation regardless of its source; or

• a trust, if a court within the United States is able to exercise primary supervision over the administration of the trust and one or more “United States persons” within the meaning of Section 7701(a)(30) of the Code has the authority to control all substantial decisions of the trust, or, if the trust has a valid election in effect under applicable U.S. Treasury Regulations to be treated as a United States person.

As used herein, the term “non-U.S. Holder” means a beneficial owner of NTS’s common stock (other than a partnership or other entity or arrangement treated as a partnership for U.S. federal income tax purposes) who is not a U.S. Holder.

If a partnership (including any entity treated as a partnership for United States federal income tax purposes) holds shares of NTS’s common stock, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. A partnership holding shares of NTS’s common stock, and each partner in such partnership, should consult its own tax advisors regarding the tax consequences resulting from the exchange of their shares of NTS’s common stock for cash pursuant to the merger agreement.

Each shareholder is encouraged to consult his, her or its own tax advisor as to the particular United States federal income tax consequences to such shareholder of exchanging his, her or its shares of NTS’s common stock solely in exchange for cash pursuant to the merger agreement, and the effect of any state, local and foreign tax laws and other tax consequences with respect to such exchange.

Exchanging U.S. Holder

A U.S. Holder that exchanges shares of NTS’s common stock for cash pursuant to the merger will be treated for U.S. federal income tax purposes as having sold such stock in a taxable sale. Such U.S. Holder will generally recognize capital gain or loss equal to the difference between the amount of cash received and the U.S. Holder’s adjusted tax basis in the shares of NTS’s common stock surrendered therefor. Generally, a U.S. Holder’s tax basis in shares of NTS’s common stock will be equal to the cost of such shares to the U.S. Holder. Any gain or loss recognized by a U.S. Holder will be capital gain or loss, and will be long-term capital gain or loss if the holding period of the surrendered shares exceeds one year as of the date of the exchange. If a U.S. Holder acquired different blocks of NTS’s common stock at different times and at different prices, gain or loss must be calculated separately for each block. Long-term capital gains recognized by a non-corporate shareholder are subject to tax at reduced rates. There are limitations on the deductibility of capital losses.

Certain U.S. Holders (e.g., an individual, estate, or a trust that does not fall into a special class of trusts that is exempt from such tax) will be subject to an additional 3.8% Medicare tax on the lesser of (1) the U.S. Holder’s “net investment income” for the relevant taxable year and (2) the excess of the U.S. Holder’s modified adjusted gross income for the taxable year over a certain threshold (which in the case of individuals will be between $125,000 and $250,000 depending on the individual’s circumstances). Net investment income generally includes dividends, and net gains from the disposition of common stock, unless such net gains are derived in the ordinary course of the

50

conduct of a trade or business (other than a trade or business that consists of certain passive or trading activities). A U.S. Holder that is an individual, estate or trust should consult its tax advisor regarding the applicability of the Medicare tax to any gain in respect of its disposition of our common stock pursuant to the merger.

Exchanging Non-U.S. Holder

Any gain realized by a non-U.S. Holder on a sale of NTS’s common stock for cash pursuant to the merger agreement generally will not be subject to United States federal income tax unless:

• the gain is effectively connected with the non-U.S. Holder’s conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, the non-U.S. Holder maintains a United States permanent establishment to which such gain is attributable);

• the non-U.S. Holder is an individual who is present in the United States for 183 days or more in the taxable year of the disposition and certain other conditions are met; or

• shares of NTS’s common stock constitute “United States real property interests” by reason of NTS’s status as a United States real property holding corporation (“USRPHC”) for United States federal income tax purposes at any time within the shorter of the five-year period preceding the disposition or the non-U.S. Holder’s holding period for NTS’s shares. NTS believes that it is not and has not been a USRPHC during the five-year period preceding the merger.

A non-U.S. Holder described in the first bullet point above will be required to pay United States federal income tax on the net gain derived from the disposition of NTS’s common stock generally in the same manner as if such non-U.S. Holder were a U.S. Holder, and, if such non-U.S. Holder is a foreign corporation, an additional branch profits tax at a 30% rate (or a lower rate if so specified by an applicable income tax treaty) may apply to any effectively connected earnings and profits.

A non-U.S. Holder described in the second bullet point above will be subject to United States federal income tax at a rate of 30% (or, if applicable, a lower treaty rate) on the gain derived from the disposition of NTS’s common stock, which may be offset by certain U.S. source capital losses.

A Non-U.S. Holder is encouraged to consult his, her or its own tax advisor regarding the United States federal income tax consequences of exchanging his, her or its shares of NTS’s common stock solely in exchange for cash pursuant to the merger agreement, as well as the applicability and effect of state, local, foreign and other tax laws.

Reporting and Backup Withholding

Payments made in connection with the merger to holders of NTS’s common stock may be reported to the IRS. In addition, under the United States federal income tax laws, backup withholding at the statutory rate (currently 28%) may apply to the amount paid to certain shareholders who are not “exempt” recipients. To prevent such backup United States federal income tax withholding, a U.S. Holder who does not otherwise establish an exemption from backup withholding must provide us with such shareholder’s taxpayer identification number (employer identification number or social security number) and provide certain other information by completing, under penalties of perjury, the IRS Form W-9. Failure to timely provide the correct taxpayer identification number on the IRS Form W-9 may subject the shareholder to a $50 penalty imposed by the IRS.

Certain “exempt” recipients are not subject to these backup withholding requirements. For a non-U.S. Holder to qualify for such exemption, such non-U.S. Holder must submit a statement (generally, an IRS Form W-8BEN or other applicable Form W-8), signed under penalties of perjury, attesting to such non-U.S. Holder’s exempt status.

Backup withholding is not an additional tax. Taxpayers may use amounts withheld as a credit against their United States federal income tax liability or may claim a refund of such amounts if they timely provide certain required information to the IRS.

51

Shareholders should consult their own tax advisors regarding the application of backup withholding to their particular circumstances and the availability of, and procedure for obtaining, an exemption from backup withholding.

THE TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL INFORMATION ONLY AND IS NOT TAX ADVICE. YOU ARE ENCOURAGED TO CONSULT YOUR TAX ADVISOR TO DETERMINE THE PARTICULAR TAX CONSEQUENCES TO YOU OF THE MERGER, INCLUDING THE APPLICABILITY AND EFFECT OF STATE, LOCAL, FOREIGN AND OTHER TAX LAWS.

Regulatory Matters

Except for the filing of the certificate of merger (including the plan of merger) and amended and restated articles of incorporation with the Secretary of State of the State of California at or before the effective time, NTS is unaware of any material federal, state or foreign regulatory requirements or approvals that would be necessary for the consummation of the merger. The certificate of merger and amended and restated articles of incorporation will not be filed until immediately prior to the effective time.

While one of the mutual conditions to closing is that any applicable waiting period under the HSR Act shall have expired or been terminated, the parties have determined that no filing is required under the HSR Act in connection with the transactions contemplated by the merger agreement.

Interests of NTS Executive Officers and Directors in the Merger

When considering NTS’s board of directors’ recommendation that Company shareholders vote in favor of the merger agreement proposal, you should be aware that NTS’s directors and executive officers have interests in the merger that are different from, or in addition to, the interests of its shareholders generally. These interests may present them with actual or potential conflicts of interest, and these interests, to the extent material, are described below. NTS’s board of directors was aware of these interests and considered them, among other matters, when it approved the merger agreement and determined that the merger agreement and the transactions contemplated thereby, including the merger, are advisable, fair to and in the best interests of NTS and its shareholders.

Positions with Surviving Corporation

Following the consummation of the merger, it is expected that the members of NTS’s senior management will hold substantially similar positions with NTS, as the surviving corporation in the merger. Further, each of the NTS executive officers is anticipated to have an employment agreement with the surviving corporation.

Stock Ownership

Certain NTS executive officers and directors beneficially own shares of NTS common stock. For a more detailed description of these stockholdings, see “Security Ownership of Certain Beneficial Owners and Management” on page 86.

52

The following table sets forth the cash consideration that NTS directors and executive officers, individually and as a group, will be entitled to receive under the merger agreement in consideration for the cancellation of common stock held by them. For purposes of the table below, it is assumed that the number of shares of common stock of NTS reflects the individual holdings of each director and executive officer as of August 15, 2013 and it is further assumed that none of the directors or executive officers will acquire or dispose of any shares of common stock prior to the closing of the merger.

(1) Such amounts include restricted shares for which acceleration shall vest for the following directors and executive officers in connection with merger as described below: Foster, 5,445; Gibbons, 5,445; Lin, 5,445; Tringali, 10,887; Wolfe, 5,445 and Yates, 5,445.

(2) Such shares include 1,019,316 shares held by Gilcy Partners Ltd., a limited partnership, and 5,400 shares held by the Cohen Family Trust, for which Mr. Cohen has an indirect pecuniary interest.

(3) Mr. Jacobs is the board designee of Mill Road Capital, L.P., which beneficially owns (a) 1,362,556 shares of NTS common stock, and (b) warrants to purchase 300,000 shares of NTS common stock that will be cancelled in connection with the merger in exchange for the right to receive the product of (i) the per share merger consideration minus the exercise price per share of the warrant and (ii) the number of shares of NTS common stock underlying the warrant. Mr. Jacobs does not possess a pecuniary interest in any of our shares of common stock or warrants owned by Mill Road Capital, L.P.

Stock Options

Certain NTS executive officers and directors hold stock options granted pursuant to NTS’s 2002 Stock Option Plan, which was subsequently replaced by the 2006 Equity Incentive Plan. The 2002 Stock Option Plan is administered by the compensation committee of the board of directors of NTS (the “Compensation Committee”) and authorized NTS to grant incentive and non-qualified stock options to employees and directors. Pursuant to the terms of the 2002 Stock Option Plan, upon a change in control of NTS, NTS and any successor corporation may agree to, among other things, terminate the 2002 Stock Option Plan, cancel all outstanding options effective as of the date of the change in control and pay the optionees the difference between the fair market value of a share as of the date of the change in control and the per share exercise price, multiplied by the number of unexercised shares to which the option relates, subject to certain restrictions relating to “parachute payments,” as described in Section 280G of the Internal Revenue Code.

All of NTS’s outstanding stock options under the 2002 Stock Option Plan were fully vested prior to the execution of the merger agreement. The merger qualifies as a change in control of NTS pursuant to the 2002

53

Stock Option Plan. Pursuant to the terms of the merger agreement, each stock option that is outstanding and unexercised as of the closing of the merger will be cancelled in the merger in exchange for an amount in cash (without interest and subject to any applicable withholding taxes) equal to the product of (1) the excess, if any, of the per share merger consideration over the applicable exercise price per share of such stock option, and (2) the aggregate number of shares of common stock issuable upon exercise of such stock option; provided that if the exercise price per share of an option is equal to or greater than the per share merger consideration, then the option will be cancelled in the merger without any cash payment being made in respect of such option. Each stock option that is currently outstanding, including those held by NTS directors and executive officers, has a per share exercise price below the per share merger consideration of $23.00.

The following table sets forth the cash consideration that NTS directors and executive officers, individually and as a group, will be entitled to receive under the merger agreement in consideration for the cancellation of stock options held by them. For purposes of the table below, it is assumed that the number of shares subject to stock options reflects the individual holdings of each director and executive officer as of August 15, 2013 and it is further assumed that none of the options will be exercised prior to the closing of the merger.

Restricted Stock

Certain NTS directors hold shares of restricted stock subject to stock awards granted pursuant to NTS’s 2006 Equity Incentive Plan. The restricted stock vests over a period of four years on an annual basis on the anniversary of the grant date. The 2006 Equity Incentive Plan is administered by the Compensation Committee and authorizes NTS to grant incentive and non-qualified stock options as well as stock awards to employees or non-employee directors. Pursuant to the terms of the 2006 Equity Incentive Plan, if there is a change in control, the board of directors of NTS may, among other things, provide for the cancellation of all or any part of the awards for a cash payment to the participants. The merger qualifies as a change in control of the company pursuant to the 2006 Equity Incentive Plan. Pursuant to the terms of the merger agreement, each share of restricted stock will become fully vested in connection with the merger. At the closing of the merger, all shares of Company common stock outstanding immediately prior to the effective time will be cancelled in exchange for

54

an amount in cash (subject to any applicable withholding taxes) equal to the per share merger consideration of $23.00 per share.

The following table sets forth the cash consideration that NTS directors and executive officers, individually and as a group, will be entitled to receive under the merger agreement in consideration for the cancellation of restricted stock held by them. For purposes of the table below, it is assumed that the number of shares of restricted stock reflects the individual holdings of each director as of August 15, 2013 and it is further assumed that there is no granting, forfeiture, or vesting of shares of restricted stock prior to the closing of the merger.

Certain NTS executive officers hold phantom stock appreciation rights granted pursuant to NTS’s 2010 Long-Term Incentive Plan (the “LTIP”). The LTIP is administered by the Compensation Committee and provides its participants with the right to earn additional incentive cash compensation.

Awards under the LTIP consist of either phantom stock full-value awards and/or phantom appreciation-only awards. Settlement of awards generally occurs within 90 days of the earlier of: the fourth anniversary of the year of grant, a change in control of NTS, or certain qualifying terminations of employment.

NTS has the option to pay up to 50% of the value of the award, as long as NTS is publicly traded, through delivery of vested shares of NTS’s common stock valued on the basis of the prior trading day’s closing price. On October 23, 2012, the Compensation Committee of the NTS board of directors exercised its discretion to accelerate the vesting of all phantom stock appreciation rights in connection with a change of control occurring before October 23, 2014.

The merger qualifies as a change in control of NTS pursuant to the LTIP. Accordingly, in connection with the merger, the outstanding phantom stock appreciation rights will be cancelled in the merger in exchange for an amount in cash (subject to any applicable withholding taxes) equal to the product of (1) the excess of the $23.00 per share merger consideration over the applicable grant price per phantom stock appreciation right, and (2) the aggregate number of such phantom stock appreciation rights. Each phantom stock appreciation right that is

55

currently outstanding, including those held by NTS executive officers, has a per share exercise price below the per share merger consideration of $23.00.

The following table sets forth the cash consideration that NTS directors and executive officers, individually and as a group, will be entitled to receive under the merger agreement in consideration for the cancellation of phantom stock appreciation rights. For purposes of the table below, it is assumed that the number of phantom stock appreciation right reflects the individual holdings of each director and executive officer as of August 15, 2013 and it is further assumed that there is not additional granting or vesting of phantom stock appreciation rights prior to the closing of the merger.

Supplemental Employee Retirement Plan

Certain NTS executive officers are participants in NTS’s 2006 Amended and Restated Supplemental Executive Retirement Plan, as Amended and Restated Effective as of December 31, 2008 (the “SERP”), which is an unfunded nonqualified deferred compensation plan under the Internal Revenue Code of 1986, as amended. The SERP is administered by the Compensation Committee and provides its participants with the right to earn additional deferred cash compensation.

NTS credits an amount on behalf of SERP participants each year and such amount is based upon a participant’s salary, years to retirement and date of entry into the SERP. This amount may vary from participant to participant and from year to year as determined by the Compensation Committee. Accumulated credit balances accrue interest which is compounded monthly at an annualized rate of 5.5%.

Credits under the SERP vest on the basis of 20% per full year of continued service. Participants will forfeit any unvested benefits as of the date of termination of employment or other termination events, except that all unvested benefits shall become fully vested if termination of employment is due to retirement, death or disability of a participant. In the event a participant’s service is terminated for cause, his SERP benefit and any future benefit payments are subject to immediate forfeiture.

Additionally, all unvested benefits will become fully vested for participants with ten or more years of service with NTS upon a change of control of NTS. The merger qualifies as a change of control of NTS pursuant

56

to the SERP. Under the terms of the SERP, the vested benefits will be paid in five substantially equal installments commencing within 90 days following the change of control. Messrs. Briskie, Coppinger, McGinnis, and Moore have ten or more years of service with NTS and the benefits granted to them under the SERP will become fully vested in connection with the merger.

The following table sets forth the cash consideration that NTS directors and executive officers, individually and as a group, will be entitled to receive as of July 31, 2013 under the merger agreement in consideration for the payment of benefits under the SERP. The figures below include both benefits which have already vested prior to the merger and benefits whose vesting will be accelerated in connection with the merger.

Change in Control Agreements

NTS has entered into change in control agreements with certain of its executive officers. The agreements provide that the executive officers could be entitled to certain severance benefits following a change in control of NTS, if either their employment is terminated by NTS without cause or they resign their employment for good reason following certain adverse material changes to the terms of their employment. The terms “cause” and “good reason” are defined in each executive officer’s change in control agreement. The merger qualifies as a change in control of NTS pursuant to the change in control agreements.

Pursuant to the change in control agreement, if an executive officer experiences a qualifying termination of employment within twelve months following a change in control of NTS, he will receive a payment equal to two times his “annual compensation” (as defined in the change in control agreement), the same percentage of Company-paid health insurance benefits as were provided before the change in control for two years after termination of employment, and full accelerated vesting of all outstanding stock options.

If the qualifying termination of employment occurs between twelve and twenty-four months following a change in control of NTS, the executive officer will receive a payment equal to one times his annual compensation, the same percentage of Company-paid health insurance benefits as were provided before the change in control for one year after termination of employment, and full accelerated vesting of all outstanding stock options.

With respect to Michael El-Hillow, however, NTS’s chief financial officer, upon a qualifying termination of employment within twelve months following a change in control of NTS, he will receive a payment equal to one times his “annual compensation” (as defined in the change in control agreement) and the same percentage of

57

Company-paid health insurance benefits as were provided before the change in control for one year after termination of employment.

Payment of severance benefits are conditioned on the executive officer providing NTS with a release of claims and executing a separation agreement with NTS which must become effective within 55 days after termination of employment and not revoking such release. The cash severance will be paid in a single lump sum payment between the 55th and 70th day after termination of employment. In addition, the severance benefits for an executive officer will be reduced if the executive officer would retain a greater amount of after-tax benefits by avoiding the imposition of golden parachute excise taxes under Code Sections 280G and 4999.

Notwithstanding any provision to the contrary, under the change in control agreements, NTS has no obligation to make any payment or offer any benefits to an executive officer if his employment is terminated prior to a change in control, or if his employment is terminated within a certain period following a change in control for cause, death, disability, retirement or resignation other than for good reason.

The following table sets forth each of NTS’s executive officers with whom NTS has entered into such change in control agreements, as well as the cash severance payment and the value of the health insurance benefits that would be due to such executive officer upon a qualifying termination of employment within twelve months following the merger and within twelve and twenty-four months following the merger. It is assumed for purposes of this proxy statement that the amounts to be paid set forth below do not account for any possible reductions to avoid the imposition of taxes under Code Sections 280G and 4999. The following table sets forth the cash consideration that NTS directors and executive officers, individually and as a group, will be entitled to receive as of August 22, 2013 under the merger agreement in consideration for the payment of benefits under the change in control agreements. Since all outstanding stock options were fully vested prior to the execution of the merger agreement, there is no accelerated vesting of stock options being providing as a result of the merger. NTS non-employee directors are not entitled to any such payments.

Directors and Executive Officers as a Group		3,524,927		159,550		3,684,477

(1) In the event that the executive officer experiences a qualifying termination of employment between twelve and twenty-four months after the merger, such executive officer will receive half of the cash and health benefits described in the above columns (other than with respect to Mr. El-Hillow, who will not receive any benefits if such a termination occurs during such time period).

Letter Agreement

NTS entered into a Letter Agreement dated April 5, 2012 (the “Letter Agreement”) with Raffy Lorentzian, former Chief Financial Officer of NTS, regarding his separation from NTS, which occurred on July 31, 2012. In exchange for the severance payments, Mr. Lorentzian agreed to provide a release of claims with respect to his employment with NTS.

Under the Letter Agreement, if a change in control event occurs within eighteen months following the termination date, Mr. Lorentzian will be entitled to payment of $220,420 (which is equal to one year’s base

58

salary), or a prorated portion of that amount if the change in control event occurs between 19 and 36 months following the termination date. Such payment will be made within 30 days following the change in control event.

The merger qualifies as a change in control of NTS pursuant to the Letter Agreement. Based on a change in control occurring before February 2014, Mr. Lorentzian will receive a lump sum payment of $220,420 within 30 days of the closing of the merger.

Indemnification and Insurance

The merger agreement contains the following provisions with respect to the indemnification of, and maintenance of liability insurance policies covering, the directors and officers of NTS.

Until the sixth anniversary of the effective time of the merger, Parent shall cause the surviving corporation to fulfill and honor in all respects the obligations of NTS to its current and former directors and officers pursuant to any indemnification provisions under NTS’s articles of incorporation, bylaws and any indemnification agreement which was provided to Parent between NTS and its current and former directors and officers and that was in effect as of August 15, 2013 with respect to claims arising out of acts or omissions occurring prior to the effective time of the merger. Each of NTS’s directors and executive officers are party to an indemnification agreement with NTS as of August 15, 2013.

Prior to the effective time of the merger, Parent is required to purchase directors’ and officers’ liability insurance coverage for a period of six years after the effective time of the merger for NTS’s current directors and officers for acts or omissions occurring prior to the merger. The material terms of such insurance coverage, including coverage and amount, are required to be no less favorable in any material respect to such directors and officers than NTS’s existing policies as of August 15, 2013. However, Parent is not required to pay annual premiums for such liability insurance in excess of 200% of the amount of the annual premiums paid by NTS for fiscal year 2013 for such purpose, provided that Parent shall nevertheless be obligated to provide as much coverage as may be obtained for such 200% amount.

Employee Benefits

For twelve months after the effective time of the merger (or if earlier, the date of the employee’s termination of employment), Parent will cause the surviving corporation and its subsidiaries, as applicable, to provide the employees of NTS and its subsidiaries who remain employed immediately after the effective time of the merger with base salary and target cash bonus opportunities (but not equity-based compensation) that are, in the aggregate, no less favorable to the base salary and target cash bonus opportunities provided by NTS and its subsidiaries on the date of the merger agreement. The employees covered by this provision will remain at-will employees in all respects.

The employees of NTS and its subsidiaries that continue to provide service after the effective date may become eligible to participate in employee benefit plans, programs, policies, and arrangements that are sponsored or maintained by Parent. Parent will use commercially reasonable efforts to, or will cause the surviving corporation to, recognize all service of such employees, as if such service were with Parent or any of its subsidiaries for purposes of eligibility to participate, vesting and benefit levels based on seniority. However, such service will not be recognized (i) for benefit accrual purposes under any Parent benefit plan that is a defined benefit pension plan, or (ii) to the extent that such recognition would result in a duplication of benefits.

Golden Parachute Compensation Arrangements

As discussed above, NTS has entered into various compensatory agreements with its named executive officers that specify certain payments and benefits to be provided upon various circumstances, including, among other things, upon a qualifying termination of employment or a change in control of NTS. In accordance with the

59

SEC’s compliance rules regarding golden parachute compensation, the Golden Parachute Compensation table below sets forth the estimated amounts of compensation that each named executive officer could receive as a result of the proposed merger transaction. The estimates below are based in part on the following assumptions:

• before taking into account any acceleration of vesting provided at the closing of the merger, whether or not an equity compensation award is vested is determined as of the day before the closing of the merger;

• the merger, which will constitute a change in control of NTS, hypothetically closed on August 26, 2013, the latest practicable date prior to the filing of this proxy statement and all then unvested equity compensation awards became vested immediately prior to such closing;

• the price per share of Company common stock paid in the merger was $23.00 which is the per share price payable under the merger agreement; and

• each named executive officer hypothetically experienced a qualifying involuntary termination of employment (as discussed in more detail above) as of the end of the day on which the merger hypothetically closed, except for Raffy Lorentzian, whose employment terminated on July 31, 2012.

Certain of the amounts payable may vary depending on the actual date of completion of the merger and any qualifying involuntary termination of employment, and may be subject to additional conditions, as described in greater detail below. No named executive officer is entitled to any tax reimbursement payments from NTS.

Golden Parachute Compensation

Named Executive Officer	Cash (1)(2)($)		Equity (3)($)		Pension/ NQDC (4)($)		Perquisites/ Benefits ($)(5)		Total ($)(6)
William McGinnis		1,096,521		2,906,250		269,378		49,907		4,322,056
Dwight Moore		761,928		1,650,750		124,676		37,277		2,574,631
Douglas Briskie		702,282		1,453,125		108,673		17,829		2,281,909
Raffy Lorentzian		220,420		—		—		—		220,420

(1) Cash. William McGinnis, Dwight Moore and Douglas Briskie are parties to change in control agreements that provide for severance benefits if the officer’s employment is involuntarily terminated after a change in control (see the section above entitled “Change in Control Agreements”). The actual magnitude of the severance benefits depends on how soon after the change in control the termination event occurs.

The figures in this column represent an estimated value of payment(s) equal to the product of two times the executive’s aggregate cash compensation for the twelve months ending August 22, 2013, which would be paid in a lump sum within 70 days of the termination of employment.

Payment of the compensation and/or benefits provided by the change in control agreements described in the table below is conditioned on (i) the executive executing a separation agreement containing a release of all claims against NTS its directors, officers and affiliates (a “Release”) within 55 days of his termination date and (ii) the executive not breaching or revoking the Release, as discussed in more detail above in the section entitled “Change in Control Agreements.”

As described in the section above entitled “Change in Control Agreements,” the change in control agreements provide that if the total payments received by a named executive officer in connection with a change in control are subject to excise tax under the “golden parachute” rules of Internal Revenue Code Section 280G, such payments will be reduced so that no such excise tax will apply if the executive would be financially better off on a net after-tax basis. For purposes of the above table, it has been assumed that no reduction was effected.

Except for the amount allocated to Raffy Lorentzian pursuant to his Letter Agreement as described further in footnote 2, amounts included in this column are all “double trigger” in nature; namely, eligibility to

60

receive these amounts requires both the occurrence of a change in control and a qualifying involuntary termination of employment within a specified period of time following such change in control.

(2) Raffy Lorentzian is party to a Letter Agreement that provides for payment if a change in control occurs within three years following Mr. Lorentzian’s termination date (see the section above entitled “Letter Agreement” for further information about the Letter Agreement). Mr. Lorentzian’s employment was terminated as of July 31, 2012. Although Mr. Lorentzian is not currently an employee of NTS, he is considered a named executive officer for the mostly recently completed fiscal year end.

The value in this column for Mr. Lorentzian is a lump sum payment equal to one year’s base salary, as provided under the Letter Agreement. This amount is “single trigger” in nature; namely, eligibility to receive this amount only requires the occurrence of a change in control within a specified period of time following Mr. Lorentzian’s termination date.

(3) Equity. The merger agreement provides, among other things, that all outstanding and unvested stock options and phantom stock appreciation rights shall become fully vested and exercisable immediately prior to the closing of the merger and shall be cancelled and converted into the right to receive consideration upon the closing of the merger.

The figures in this column represent the aggregate payments to be made in respect of unvested phantom stock appreciation only rights with a per share exercise price that is less than the per share merger consideration, for which vesting will be fully accelerated in connection with the merger, as described in greater detail above in “The Merger — Interests of NTS Executive Officers and Directors in the Merger.” All of the stock options held by the named executive officers are fully vested and therefore are not included in this table.

Amounts included in this column are all “single-trigger” in nature; namely, eligibility to receive the payment is conditioned solely on the occurrence, and being employed as, of a change in control.

(4) Pension/NQDC. Messrs. McGinnis, Moore, and Briskie are participants in NTS’s 2006 Supplemental Executive Retirement Plan, as amended (the “SERP”), as described above in “The Merger — Interests of NTS Executive Officers and Directors in the Merger.” Under the SERP, each participant who has completed ten or more years of service with NTS at the time of a change of control shall receive full vesting of the unvested contributions that were made by NTS under the SERP on behalf of the participant. Messrs. McGinnis, Moore, and Briskie have each provided service to NTS for more than ten years and therefore qualify to receive this acceleration of vesting benefit. Under the SERP, payment of benefits is scheduled to occur in five annual pro rata installments commencing within 90 days following the change of control.

Amounts included in this column are all “single-trigger” in nature; namely, eligibility to receive the payment is conditioned solely on the occurrence, and being employed as, of a change in control.

Payments to Raffy Lorentzian under the SERP are not reflected in this column as his benefits have already vested and annual payments began following his termination of service on July 31, 2012.

(5) Perquisites/benefits. As described above in footnote 1 to this Golden Parachute Compensation table, William McGinnis, Dwight Moore and Douglas Briskie are parties to change in control agreements that provide for severance benefits, including continued participation by the executive and his eligible dependents in health insurance benefit plans for up to 24 months following the termination date.

The figures in this column represent an estimated value of continued participation by the executive and his eligible dependents in health insurance benefit plans for 24 months following the termination date as provided under the change in control agreement.

Amounts included in this column are all “double trigger” in nature; namely, eligibility to receive these amounts requires both the occurrence of a change in control and a qualifying involuntary termination of employment following the change in control.

61

(6) Total. The following table shows, for each named executive officer, the golden parachute compensation amounts which are single trigger or double trigger in nature.

Named Executive Officer	Single Trigger ($)		Double Trigger ($)
William McGinnis		3,175,628		1,146,428
Dwight Moore		1,775,426		799,205
Douglas Briskie		1,561,798		720,111
Raffy Lorentzian		220,420		—

Litigation Relating to the Merger

On August 23, 2013, one week after the announcement of the merger, a putative shareholder class action lawsuit, entitled Elias v. National Technical Systems, Inc., Case No. BC519271, was filed in the Superior Court of the State of California, Los Angeles County, against NTS, the members of NTS’s board of directors, Aurora Capital Group, Parent and Merger Sub. The lawsuit asserts a claim for breach of fiduciary duty against the members of NTS’s board of directors. The lawsuit also alleges that NTS has not provided sufficient information about the merger to shareholders. The lawsuit further asserts that NTS, Aurora Capital Group, Parent and Merger Sub aided and abetted the alleged breaches of fiduciary duty. The lawsuit seeks to enjoin the consummation of the merger, damages, costs, attorneys’ and experts’ fees, and any other relief the court may deem proper. Each of the defendants believes that the lawsuit is without merit and intends to defend it vigorously. A status conference has been scheduled for November 6, 2013.

DISSENTING SHAREHOLDER RIGHTS

The discussion of the provisions set forth below is not a complete summary regarding your dissenting shareholder rights under California law and is qualified in its entirety by reference to the full text of Chapter 13 of the California General Corporation Law, which is attached to this proxy statement as Annex C and incorporated herein by reference. Shareholders intending to exercise their dissenting shareholder rights to have NTS purchase, at the fair market value, the shares of NTS’s common stock held by them should carefully review Annex C. FAILURE TO FOLLOW PRECISELY ANY OF THE STATUTORY PROCEDURES SET FORTH IN ANNEX C MAY RESULT IN A TERMINATION OR WAIVER OF THESE RIGHTS. COMPANY SHAREHOLDERS WHO ARE CONSIDERING ASSERTING AND EXERCISING DISSENTING SHAREHOLDER RIGHTS SHOULD CONSULT THEIR LEGAL ADVISORS.

If the merger is completed, any holder of shares of NTS’s common stock as of the record date may, by complying with the provisions of Chapter 13 of the California General Corporation Law, require NTS to purchase such holder’s shares of NTS’s common stock at the fair market value in lieu of receiving the per share merger consideration for their shares. The fair market value will be determined as of the day of, and immediately prior to, the first public announcement of the terms of the proposed merger (which occurred on the morning of August 16, 2013), excluding any appreciation or depreciation in consequence of the proposed merger. Shareholders should be aware that an investment banking opinion as to the fairness from a financial point of view of the consideration payable in a transaction such as the proposed merger is not an opinion as to, and does not in any way address, fair market value for purposes of Chapter 13 of the California General Corporations Law.

If a Company shareholder has a beneficial interest in shares of NTS’s common stock that are held of record in the name of another person, such as a trustee or nominee, and such shareholder desires to perfect any dissenting shareholder rights such beneficial shareholder may have, such beneficial shareholder must act promptly to cause the holder of record to timely and properly follow all the steps summarized below. Dissenting shareholder rights cannot be validly exercised by persons other than shareholders of record regardless of the beneficial ownership of the shares.

Exercise of your rights as a dissenting shareholder under California law requires strict compliance with the procedures set forth in Chapter 13 of the California General Corporation Law. Failure to follow any of these procedures may result in a termination or waiver of dissenting shareholder rights under California law. The applicable provisions of California law are summarized below. NTS shareholders who choose to exercise dissenting shareholder rights under California law must fully comply with the requirements of Chapter 13 of the California General Corporation Law.

Under the California General Corporation Law, a Company shareholder may be entitled to dissenting shareholder rights with respect to the shares of NTS’s common stock held by such shareholder if:

• such shares were outstanding on September 20, 2013, the record date of the special meeting;

• such shares were voted “AGAINST” the merger proposal; and

• NTS or its transfer agent has received by no later than the date of the special meeting a written demand from such shareholder that NTS purchase such shares at their fair market value (as described below).

If you desire to exercise dissenting shareholder rights and receive the fair market value of your shares of our common stock in cash instead of the per share merger consideration, your shares must be voted “AGAINST” the merger agreement proposal. It will not be sufficient to abstain from voting or for your shares to be subject to a broker non-vote. If you return a signed proxy without indicating your voting preference or with instructions to vote “FOR” the merger agreement proposal, your shares of our common stock will be voted in favor of the merger agreement proposal and you will lose any dissenting shareholder rights. In addition, a vote against the merger agreement proposal will not, in and of itself, constitute a written demand for dissenting shareholder rights within the meaning of Chapter 13 of the California General Corporation Law.

63

Within ten days after approval of the merger agreement proposal by NTS’s shareholders at the special meeting, each shareholder who has made a written demand for dissenter’s rights pursuant to Chapter 13 of the California General Corporation Law and is entitled to dissenting shareholder rights will receive a notice of such approval and a statement of the price determined by NTS to represent the fair market value of the shares on August 16, 2013, as of immediately prior to the first public announcement of the merger. The notice will also describe the rights to which such shareholders are entitled and shall be accompanied by a copy of Sections 1300, 1301, 1302, 1303 and 1304 of Chapter 13 of the California General Corporation Law.

By no later than the date of the special meeting, NTS or its transfer agent must have received from any dissenting shareholder a written demand that NTS purchase such shareholder’s dissenting shares. The demand must set forth the number and class of shares that such shareholder desires to be repurchased, include a statement as to what such shareholder claims to be the fair market value of such shares as of the day of, and immediately prior to, the first public announcement of the proposed merger. The statement of fair market value in such demand by the dissenting shareholder constitutes an offer by the dissenting shareholder to sell the dissenting shares at such price. Dissenting shareholders should send the demand to:

National Technical Systems, Inc.

Attention: Corporate Secretary

24007 Ventura Boulevard,

Calabasas, California 91302

Such shareholder must also, within 30 days after the date on which notice of the approval of the merger agreement proposal by NTS’s shareholders is mailed to the shareholders of dissenting shares, submit to NTS (at the address set forth above) or its transfer agent, if the shares are certificated, any certificates representing any dissenting shares that the dissenting shareholder demands NTS purchase, so that such dissenting shares may either be stamped or endorsed with the statement that the shares are dissenting shares or exchanged for certificates of appropriate denomination so stamped or endorsed, or, if the shares are uncertificated, written notice of the number of dissenting shares that the dissenting shareholder demands that NTS purchase.

If the shareholder and NTS agree upon the fair market value and the shares held by such shareholder qualify as dissenting shares, such NTS shareholder will be entitled to the agreed upon price plus the legal rate of interest on judgments from the date of such agreement. If NTS shareholder and NTS are unable to agree upon the fair market value of the shares or whether the shares qualify as dissenting shares, the shareholder may file a complaint in California Superior Court seeking a determination by the court of the fair market value of the shares and/or whether the shares qualify as dissenting shares. The complaint must be filed within six months of the date on which the notice of the approval of the merger agreement proposal was mailed to NTS shareholders.

After determining which shareholders are entitled to dissenting shareholder rights, the court will evaluate the shares, determining their fair market value exclusive of any element of value arising from the accomplishment or expectation of the merger, together with a fair rate of interest, if any, to be paid upon the amount determined to be the fair market value. The court will then direct payment of the fair value of the shares, together with interest, if any, to the dissenting shareholders. Any cash dividends declared and paid upon the dissenting shares after the date of approval of the merger agreement proposal by NTS shareholders shall be credited against the total amount to be paid to the dissenting shareholders. The costs of proceedings may be determined by the court and shared by the parties as the court deems fit. Subject to the provisions of Chapter 13 of the California General Corporation Law, NTS shareholders who have exercised their dissenting shareholder rights will not have the right at law or in equity to attack the validity of the merger or to have the merger set aside or rescinded, except in an action to test whether the number of shares required to authorize or approve the merger had been legally voted in favor of the merger. In addition, if any of NTS shareholder initiates any action to attack the validity of the merger or to have it set aside or rescinded, the shareholder thereafter shall have no right to demand payment for his or her shares as a holder of dissenting shares.

64

THE MERGER AGREEMENT (PROPOSAL NO. 1)

The board of directors is asking NTS’s shareholders to vote on a proposal to approve the merger agreement and the transactions contemplated thereby, including the merger.

This section of the proxy statement summarizes some of the material terms and conditions of the merger agreement, but is not intended to be an exhaustive discussion of the merger agreement. The rights and obligations of the parties are governed by the express terms and conditions of the merger agreement and not the summary set forth in this section or any other information contained in this proxy statement. This summary is qualified entirely by reference to the complete text of the merger agreement, a copy of which is attached as Annex A to this proxy statement and is incorporated into this proxy statement by reference. NTS urges you to read the merger agreement carefully and in its entirety.

The merger agreement has been included to provide you with information regarding its terms. It is not intended to provide any other factual information about NTS, Parent, or Merger Sub. The merger agreement contains representations and warranties that the parties to the merger agreement made to and solely for the benefit of each other. In addition, the assertions embodied in the representations and warranties contained in the Merger Agreement are qualified by certain disclosure schedules that the Company has delivered to Parent. You should not rely on such representations and warranties as characterizations of the actual state of facts or circumstances.

Structure of the Merger

At the effective time of the merger, as described below, subject to the satisfaction or waiver of the conditions set forth in the merger agreement, and in accordance with the California General Corporation Law, Merger Sub will be merged with and into NTS, the separate corporate existence of Merger Sub will cease and NTS will continue NTS’s corporate existence as the surviving corporation in the merger, and as a wholly-owned subsidiary of Parent.

Closing and Effective Time of the Merger

The closing of the merger will take place at 7:00 AM pacific time on the second business day after the satisfaction or waiver of each of the conditions to closing set forth in the merger agreement or such other date and time as is agreed to in writing by Parent and NTS. The merger will become effective upon the filing of the certificate of merger with the Secretary of State of the State of California, or at such other time as Parent and NTS shall agree and specify in the certificate of merger. The time at which the merger becomes effective is hereinafter referred to as the “effective time.”

Articles of Incorporation; Bylaws

At the effective time, the articles of incorporation of the surviving corporation will be amended and restated to be identical to the articles of incorporation of Merger Sub immediately prior to the effective time, except that Article I of the articles of incorporation of the surviving corporation will read as follows: “The name of this corporation is National Technical Systems, Inc.”

At the effective time, the bylaws of the surviving corporation will be amended and restated to be identical to the bylaws of Merger Sub immediately prior to the effective time, except that all references to Merger Sub in the bylaws of the surviving corporation shall be changed to refer to “National Technical Systems, Inc.”

Directors and Officers

The directors of Merger Sub immediately prior to the effective time of the merger will be the directors of the surviving corporation until their successors have been duly elected or appointed and qualified or until their earlier death, resignation or removal.

65

The officers of NTS immediately prior to the effective time of the merger will be from and after the effective time the officers of the surviving corporation until their successors have been duly elected or appointed and qualified or until their earlier death, resignation or removal.

Consideration to be Received by NTS’s Shareholders in the Merger

At the effective time, each share of NTS’s common stock issued and outstanding, immediately prior to the effective time other than shares held by Parent, Merger Sub, and NTS (as treasury stock or otherwise) and any of their respective direct or indirect subsidiaries or by NTS’s shareholders who perfect their appraisal rights to the extent available under California law, will be converted automatically into the right to receive the per share merger consideration of $23.00 per share in cash, without interest and less any applicable withholding taxes. At the effective time, all shares of NTS’s common stock held by Parent, Merger Sub, and NTS (as treasury stock or otherwise) and any of their respective direct or indirect subsidiaries will automatically be cancelled and no payment will be made in respect of those shares.

Payment Procedures

Prior to the effective time, Parent will appoint Computershare Trust Company N.A. to act as exchange agent for purposes of exchanging the per share merger consideration for certificates of NTS common stock and book-entry shares.

At closing, Parent will deposit or cause to be deposited with the exchange agent sufficient funds to pay the aggregate per share merger consideration that is payable in respect of our outstanding common stock.

Promptly after and within five business days of the effective time, Parent will send or will cause the exchange agent to send a letter of transmittal to each record holder of shares of NTS common stock at the effective time. The letter of transmittal will contain instructions for exchanging shares of NTS common stock for the per share merger consideration.

Upon surrender to the exchange agent of a stock certificate representing shares of NTS stock, together with a duly completed and validly executed letter of transmittal, and any other documents as may reasonably be requested by the exchange agent, the holder of the stock certificate will be entitled to receive from the exchange agent $23.00 in cash (without interest and less any applicable withholding taxes) for each share represented by the stock certificate and that stock certificate will be cancelled. In the case of book-entry shares, by receipt of an “agent’s message” by the exchange agent, along with any additional evidence as may be reasonably requested by the exchange agent, the holder of book-entry shares will be entitled to receive from the exchange agent $23.00 in cash (without interest and less any applicable withholding taxes) for each book-entry share.

If any cash merger consideration is to be paid to a person or entity other than the registered shareholder listed on a surrendered stock certificate or a transferred book-entry share, as a condition to payment, such stock certificate must be properly endorsed or otherwise be in proper form for transfer, or such book-entry share must be properly transferred, and the person or entity requesting payment must pay to the exchange agent any transfer or other tax that may be required as a result of the payment.

No interest will be paid or accrued on the cash payable upon the surrender or transfer of any stock certificate or book-entry share. The cash paid upon conversion of NTS common stock in the merger will be issued in full satisfaction of all rights relating to those shares of NTS common stock.

The stock transfer books of NTS will be closed immediately upon the effective time and there will be no further registration or transfers of our common stock on the transfer books of the surviving corporation. If, after the effective time, stock certificates or book-entry shares are presented to the surviving corporation, such shares will be cancelled and exchanged for the per share merger consideration.

66

Any portion of the merger consideration made available to the exchange agent unclaimed by our shareholders six months after the effective time of the merger will be delivered to the surviving corporation, upon demand, and any shareholders who have not properly exchanged their shares of NTS common stock will thereafter look only to the surviving corporation for payment of the per share merger consideration (without interest and subject to any withholding taxes). If any stock certificates or book-entry shares are not exchanged prior to two (2) years after the effective time (or immediately prior to such earlier date on which the related per share merger consideration would otherwise escheat to or become the property of any governmental authority), any such per share merger consideration in respect thereof will, to the extent permitted by applicable law, become the property of the surviving corporation, free and clear of all claims or interest of any person previously entitled to such consideration.

If you have lost a certificate, or if it has been stolen or destroyed, then, before you will be entitled to receive the per share merger consideration, you will have to make an affidavit of the loss, theft or destruction, and, if required by Parent or the exchange agent post a bond in such amount as Parent or the exchange agent may determine is reasonably necessary as indemnity against any claim that may be made against it or the surviving corporation with respect to such certificate. These procedures will be described in the letter of transmittal that you will receive, which you should read carefully in its entirety.

Treatment of Equity Awards

Pursuant to the merger agreement, NTS must take all required action so that each option to acquire shares of NTS common stock, restricted shares of NTS common stock and restricted stock units then outstanding and unvested and/or not exercisable (irrespective of any time- or performance-based condition or other contingency), will become fully vested and exercisable in connection with the merger. At the effective time, each equity award not previously exercised will be automatically cancelled and converted solely into the right to receive, promptly after and within five business days of the effective time, a cash payment, without interest, equal to the product of:

(i) the excess, if any, of the per share merger consideration over any applicable exercise price per share of such equity award, and

(ii) the number of shares of NTS common stock for which such equity award is exercisable, without interest and subject to applicable withholdings, including for income and employment taxes (with the aggregate amount rounded down to the nearest whole cent);

provided that if the exercise price per share of any such equity award is equal to or greater than the per share merger consideration, then such equity award will be cancelled without any cash payment being made.

At or immediately prior to the effective time NTS will take all actions necessary to cancel and terminate NTS’s 2002 Stock Option Plan, 2006 Equity Incentive Plan, 2006 Long Term Incentive Plan, and 2010 Long Term Incentive Plan. No further awards or other rights with respect to shares of NTS common stock will be granted under any of the foregoing plans following termination.

Treatment of Warrants

At the effective time, each warrant exercisable for shares of NTS common stock will be terminated and converted solely into the right to receive, promptly after and within five business days of the effective time, a cash payment, without interest, equal to the product of (i) the excess, if any, of the per share merger consideration over the then effective exercise price per share under the warrant, and (ii) the number of shares of common stock for which the warrant is then exercisable, provided that if the then exercise price per share under the warrant is equal to or greater than the per share merger consideration, then any such warrant shall be cancelled without any cash payment being made in respect thereof.

67

Dissenting Shares

Subject to the terms of the merger agreement, NTS common stock which was outstanding on the record date (other than shares held by Parent, Merger Sub or NTS), which were not voted in favor of the merger, and the holders of which:

(i) have demanded that NTS purchase such shares at their fair market value in accordance with Section 1301 of the California General Corporation Law;

(ii) have submitted such shares for endorsement in accordance with Section 1302 of the California General Corporation Law; and

(iii) have not otherwise failed to perfect or shall not have effectively withdrawn or lost their rights to be entitled to require NTS to purchase their shares under the California General Corporation Law,

will not be converted into a right to receive the per share merger consideration allocable to such shares of common stock, but instead will be entitled to only such rights as are granted by Section 1300 et. seq. of the California General Corporation Law; provided, however, that if, after the effective time, such holder fails to perfect, withdraws or loses such holder’s right to appraisal pursuant to Section 1300 et. seq. of the California General Corporation Law or if a court of competent jurisdiction determines that such holder is not entitled to the relief provided by Section 1300 et. seq. of the California General Corporation Law, such shares of common stock will be treated as if they had been converted as of the effective time into the right to receive the per share merger consideration allocable thereto in accordance with the merger agreement, without interest but subject to any applicable withholdings, upon surrender of such stock certificate formerly representing such shares of common stock or transfer of such book-entry share, as the case may be.

NTS will provide Parent prompt written notice (within three business days) of any demands received by NTS for appraisal of shares of common stock, any withdrawal of any such demand and any other demand, notice or instrument delivered to NTS prior to the effective time pursuant to the California General Corporation Law that relates to such demand; provided, however, that beginning ten business days prior to the shareholders meeting, NTS will provide Parent with the written notice described above within two days of receipt by NTS of any such demand (or demand withdrawal), notice or instrument and in any event NTS will provide to Parent all such demands, withdrawals, notices and/or instruments that it is in receipt of on the day prior to the shareholders meeting and for which notice has not already been provided to Parent, and will provide notice of any such demand, withdrawal, notice or instrument received on the day of the shareholders meeting to Parent immediately following receipt. Parent will have the opportunity and right to direct all negotiations, petitions and proceedings with respect to any such demands. Prior to the effective time, NTS will not, without the prior written consent of Parent (which may be given or withheld in Parent’s sole discretion), make any payment with respect to, or settle or offer to settle, any such demands, or agree to do any of the foregoing.

Restrictions on Soliciting Other Acquisition Proposals

The merger agreement provides that NTS will not, and will not permit or authorize any of its subsidiaries or its or its subsidiaries’ representatives, directly or indirectly, to:

• initiate, solicit, endorse, propose, encourage or take any other action to facilitate (including by way of furnishing information) any proposals, offers or inquiries with respect to, that constitute, or would reasonably be expected to lead to, an acquisition proposal (as defined on page 74);

• enter into, engage, continue or participate in any negotiations concerning, or provide any confidential information or data to, or have any discussions with, any person relating to an acquisition proposal or any proposal or offer that would reasonably be expected to lead to an acquisition proposal;

• approve, endorse or recommend or propose to approve, endorse or recommend, any acquisition proposal;

• approve, endorse or recommend, or propose to approve, endorse or recommend, or execute or enter into, any letter of intent, agreement in principle, merger agreement, acquisition agreement, option agreement or other similar agreement relating to any acquisition proposal or any proposal or offer that has a primary purpose of effectuating, or would reasonably be expected to lead to, an acquisition proposal;

• make or authorize any statement, propose or resolve, proposal or agree to do any of the foregoing relating to any acquisition proposal; or

• make a change in board recommendation (as defined on page 74).

72

Notwithstanding these restrictions, at any time prior to obtaining shareholder approval of the merger agreement proposal, we may provide information about us and our subsidiaries to a person making an acquisition proposal and also engage in negotiations and discussions with any such person if:

• our board of directors determines in good faith, after consultation with outside legal counsel, that failure to take such action would be inconsistent with its fiduciary duties under applicable law;

• our board of directors determines, in good faith, based on the information then available and upon the recommendation of the special committee (after consultation with the special committee’s independent financial advisor and outside legal counsel), that such acquisition proposal constitutes a superior proposal (as defined on page 74); and

• such acquisition proposal is bona fide, written and not a result of a breach or violation of any of the obligations summarized in this proxy statement under “The Merger Agreement — Restrictions on Soliciting Other Acquisition Proposals” on page 72 and “The Merger Agreement — Ability to Change Board Recommendation / Acquisition Proposals” on page 74.

In addition, in order to provide information to a person making an acquisition proposal and to engage in negotiations and discussions with such person, our board of directors must receive from such person, (i) a confidentiality agreement containing terms substantially similar to, and no less favorable to NTS than, those set forth in the non-disclosure agreement with Aurora Capital Group (though the confidentiality agreement need not include a standstill provision), and (ii) evidence reasonably satisfactory to our board of directors of the financial capability of such person to consummate the acquisition proposal.

NTS is also obligated to promptly, but no later than two (2) business days after receipt, advise Parent in writing of any inquiry or proposal or offer related to an acquisition proposal or any request for nonpublic information relating to NTS or its subsidiaries other than requests that are not reasonably expected to be related to an acquisition proposal (including the identity of the person making or submitting such acquisition proposal or request, and the terms thereof) that is made or submitted by any person prior to the effective time. Each such notice must include the identity of the person or group of persons making such proposal, offer, request, indication or inquiry, a copy of any written proposal, offer or draft agreement provided by such person and the material terms and conditions of any proposals or offers. NTS must also keep Parent promptly and reasonably informed of the status, details and terms of any such proposals or offers (including any amendments thereto) and the status of any such discussions or negotiations (including of any amendment, modification, development, discussion or negotiation), including furnishing copies of any written inquiries, correspondence and draft documentation, and written summaries of any material oral inquiries or discussions. NTS is also obligated to promptly, and in advance of providing information or engaging in discussions, notify Parent orally and in writing if it determines to begin providing information or to engage in discussions or negotiations concerning an acquisition proposal.

NTS and the NTS board of directors may also contact a person who has made, or proposes to make an acquisition proposal and to whom NTS is permitted to provide nonpublic information pursuant to the above conditions solely to request clarifications of the terms and conditions of such acquisition proposal or to comply with certain disclosure obligations under the securities laws with regard to an acquisition proposal. Any such disclosure, other than a “stop, look and listen” communication or similar communication contemplated by Rule 14d-9(f) of the Exchange Act will be deemed a change in board recommendation (as defined on page 74) unless the board of directors reaffirms its recommendation for the merger proposal in such disclosure.

We have agreed not to terminate, waive, amend, release or modify any provision of any existing confidentiality agreement or standstill agreement to which we or any of our subsidiaries is a party with respect to any acquisition proposal or potential acquisition proposal. To the extent any such confidentiality or standstill agreement contains a provision that prohibits the counterparty to such agreement from requesting a waiver to a standstill, we are however allowed to waive our rights with respect to such prohibition.

73

The merger agreement defines an “acquisition proposal” as any inquiry, proposal or offer (other than from Parent or Merger Sub) relating to, in one or a series of transactions:

• the direct or indirect, acquisition by any person or group of persons of 15% or more of the outstanding equity interests in NTS (by vote or value);

• any merger, consolidation, business combination, reorganization, share exchange or similar transaction involving NTS that, if consummated, would result in the acquisition of 15% or more of the outstanding equity interests in NTS (by vote or value);

• any sale of assets, recapitalization, equity investment, license, joint venture, liquidation, dissolution, disposition or other similar transaction which would, directly or indirectly, result in an third party acquiring an interest in assets representing, directly or indirectly, 15% or more of the net revenues, net income, cash flow or assets of NTS and its subsidiaries, taken as a whole;

• the acquisition (whether by merger, consolidation, equity investment, share exchange, joint venture or otherwise) by any third party, directly or indirectly, of any equity interest in any person that holds assets generating or representing, directly or indirectly, 15% or more of the net revenues, net income, cash flow or assets of NTS and its subsidiaries, taken as a whole;

• any tender offer, self-tender or exchange offer that if consummated would result in any third party acquiring of 15% or more of the equity interests in NTS (by vote or by value); or

• any combination of the foregoing.

The merger agreement defines a “superior proposal” as any unsolicited bona fide binding written acquisition proposal not resulting from any violation or breach of any obligation of NTS relating to an acquisition proposal as set forth in the merger agreement, that is not subject to any financing condition or, if financing is required, such financing is then fully committed or reasonably determined to be available by the NTS board of directors, which the NTS board of directors determines in good faith, upon the recommendation of the special committee (after consultation with an independent financial advisor and outside legal counsel), and taking into consideration, among other things, all of the terms, conditions, impact and all legal, financial, regulatory and other aspects of such acquisition proposal and the merger agreement (in each case taking into account any revisions to the merger agreement made or proposed in writing by Parent prior to the time of determination), including financing, regulatory approvals, equityholder litigation, identity of the person or group making the acquisition proposal, breakup fee and expense reimbursement provisions and other events or circumstances, (A) is reasonably likely to be consummated in accordance with its terms and (B) is more favorable to the NTS shareholders from a financial point of view than the merger and the other transactions contemplated by the merger agreement; provided, that for purposes of this definition of “superior proposal,” (i) all references in the term “acquisition proposal” to “15%” shall be deemed to be references to the lesser of (a) “80%” and (b) 100% minus the number of equity interests held by officers of NTS and proposed to be rolled over into the acquirer.

Ability to Change Board Recommendation / Acquisition Proposals

The NTS board of directors unanimously, and in accordance with the unanimous recommendation of the special committee, approved the merger agreement and determined that the merger agreement and the transactions contemplated thereby are advisable, fair to and in the best interests of NTS and its shareholders.

The merger agreement provides that, subject to certain exceptions, neither our board of directors nor any of its committees may take any of the following actions (any such action is referred to as a “change in board recommendation”):

• withhold, withdraw, modify or qualify, or propose publicly to withhold, withdraw, modify or qualify, in a manner adverse to Parent or Merger Sub, the approval of the merger agreement and the merger or the recommendation of the NTS board in favor thereof (the “board recommendation”) or take any action or make any statement in connection with the special meeting inconsistent with such approval or board recommendation;

74

• adopt, approve, endorse, recommend, or otherwise declare advisable or propose to adopt, approve, endorse, recommend, or otherwise declare advisable, publicly or otherwise, any acquisition proposal;

• fail to publicly reaffirm the board recommendation within three (3) business days after Parent or Merger Sub so requests in writing;

• fail to recommend against any acquisition proposal within five (5) business days (other than an acquisition proposal described in next bullet below for which NTS shall have ten (10) business days);

• fail to recommend, in a Solicitation/Recommendation Statement on Schedule 14D-9, against any acquisition proposal subject to Regulation 14D under the Exchange Act, within ten (10) business days after the commencement of any such acquisition proposal;

• fail to include the board recommendation in the NTS proxy statement;

• cause or permit NTS or any of its subsidiaries to enter into any letter of intent, memorandum of understanding, agreement in principle or similar document or contract constituting or relating to any acquisition proposal (other than a confidentiality agreement entered into in accordance with, and meeting the requirements described above under “The Merger Agreement — Restrictions on Soliciting Other Acquisition Proposals”);

• make any other public statement that is inconsistent with the board recommendation; or

• resolve, agree or propose to take any of the foregoing actions.

However, at any time prior to obtaining shareholder approval of the merger agreement proposal, the NTS board of directors may make a change in board recommendation, or terminate the merger agreement to enter into an alternative transaction agreement, in each case in response to a superior proposal if the following conditions are satisfied:

• the NTS board of directors determines in good faith after consultation with outside legal counsel that the failure to take such action would be inconsistent with its fiduciary duties under applicable law;

• NTS complied with each of the obligations in the merger agreement relating to a change in board recommendation, or resulting in the acquisition proposal that led to the superior proposal;

• NTS provided at least five (5) business days advance written notice (such period is referred to as the “notice period”) to Parent of the acquisition proposal and the board of directors good faith conclusion that such proposal constitutes a superior proposal and the board of director’s intent to terminate the merger agreement, absent any revisions to its terms and conditions (which such notice must include the reason for such intent, the identity of the person or group of persons making the superior proposal and its terms and conditions and a copy of the definitive acquisition agreement and any other relevant transaction documents);

• prior to effecting the termination of the merger agreement:

• during the notice period, NTS negotiated (and caused its financial and legal advisors to negotiate) with Parent in good faith (to the extent requested by Parent) regarding any revisions to the terms of the merger agreement, and

• if Parent made a proposal during the notice period, at the end of such notice period, the NTS board of directors, after taking into consideration the adjusted terms and conditions of the merger agreement as proposed by Parent, determined in good faith, upon the recommendation of the special committee (after consultation with outside legal counsel and the special committee’s financial advisor), that:

• the acquisition proposal continues to constitute a superior proposal;

• after consultation with outside legal counsel, that the failure to terminate the merger agreement would be inconsistent with the board of directors fiduciary duties under applicable law; and

75

• in the case of a termination of the merger agreement by NTS to enter into an alternative transaction agreement, paid to Parent concurrently with such termination of the $11.0 million termination fee.

In the event that there is a revision to the financial terms or any other material terms of a superior proposal for which NTS is seeking to effect a change in board recommendation or to terminate the merger agreement in order to enter into an alternative transaction agreement, NTS is required to deliver a new written notice to Parent in the form descried above and to comply with each of the requirements described above prior to effecting such recommendation or terminating the merger agreement.

In addition to foregoing, at any time prior to obtaining shareholder approval of the merger agreement proposal, the NTS board of directors may make a change in board recommendation in response to an intervening event (as defined below on page 76) if the following conditions are satisfied:

• the NTS board of directors determines in good faith after consultation with outside legal counsel that the failure to take such action would be inconsistent with its fiduciary duties under applicable law;

• NTS provided Parent with written information describing such intervening event in reasonable detail as soon as reasonably practicable after becoming aware of it;

• NTS kept Parent reasonably informed of developments with respect to such intervening event;

• NTS notified Parent in writing at least five (5) business days before making such a change in board recommendation and the reason for such change;

• if Parent makes a proposal during the five (5) business day period described above to adjust the terms and conditions of the merger agreement, the NTS board of directors, after taking into consideration the adjusted terms and conditions of the merger agreement as proposed by Parent, determined in good faith, after consultation with outside counsel, that the failure to make such change in board recommendation would result in a breach of the fiduciary duties of the NTS board of directors under applicable law; and

• during such five (5) business day period, NTS negotiated (and caused its financial and legal advisors to negotiate) with Parent in good faith (to the extent requested by Parent) regarding any revisions to the terms of the merger agreement as proposed by Parent.

The merger agreement defines an “intervening event” as a material event or circumstances that was not known to the NTS board of directors prior to the execution of the merger agreement (or if known, the consequences of which were not known or reasonably foreseeable), which event or circumstance, or any material consequence thereof, becomes known to the NTS board of directors prior to obtaining shareholder approval of the merger agreement proposal; provided, that in no event shall the receipt, existence or terms of an acquisition proposal or any matter relating thereto or consequence thereof constitute an intervening event.

Parent has agreed to, and to cause Merger Sub to, use its reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable to arrange and obtain the debt financing on the terms and conditions described in the debt financing commitment letter, including using reasonable best efforts to:

• maintain in effect the debt financing commitment;

• satisfy on a timely basis all conditions applicable to Parent or Merger Sub to obtaining the debt financing (including by consummating the equity financing at or prior to closing);

• enter into definitive agreements with respect to the debt financing on terms and conditions contained in the debt financing commitment or consistent in all material respects with the debt financing

76

commitment, or on other terms that would not materially and adversely impact the ability of Parent to timely consummate the transactions contemplated by the merger agreement; and

• draw down on the debt financing if the conditions to the availability of the debt financing have been satisfied or waived.

Parent has also agreed not to, and to cause Merger Sub not to, agree to or permit any amendment, supplement or other modification of, or waive any of its rights under, any debt financing commitment or any definitive agreements related to the debt financing, if such amendment, supplement, modification or waiver would:

• (i) reduce the aggregate amount of the debt financing, or (ii) impose new or additional conditions, or otherwise amend, modify or expand any conditions to the receipt of the debt financing in a manner that would reasonably be expected to (a) materially delay or prevent the closing date, or (b) make the funding of the debt financing (or the satisfaction of the conditions to obtaining the debt financing) materially less likely to occur; or

• materially adversely impact the ability of Parent or Merger Sub to enforce their rights against the other parties to the debt financing commitment or the definitive agreements with respect thereto, the ability of Parent and Merger Sub to consummate the closing or the likelihood of consummation of the closing, in each case, without NTS’s prior written consent.

Notwithstanding the foregoing, Parent and Merger Sub may amend the debt financing commitment or any definitive agreements related to the debt financing to add lenders, lead arrangers, bookrunners, syndication agents, other funding sources, additional equity financiers or similar entities who had not executed the debt financing commitments as of August 15, 2013. Parent is obligated, upon any amendment, supplement or modification of the debt financing commitment to provide a copy of such amendment, supplement or modification to NTS.

Parent has also agreed to (i) keep NTS reasonably apprised of developments relating to the debt financing, and (ii) provide prompt notice of any material breach or default by any party to the debt financing commitment of which Parent becomes aware or any written communication from any person with respect to any actual or purported material breach, termination or repudiation by any party to the debt financing commitment.

As an alternative to the credit facilities provided for in the debt commitment letter, Parent and Merger Sub may obtain substitute financing in the form of a single lien senior secured credit facility so long as the replacement of the credit facilities with the substitute financing would not be adverse in any material respect to NTS, taking the credit facilities and substitute financing as a whole. Parent and Merger Sub currently intend to utilize such substitute financing and expect it to be in the form of a $183.0 million senior secured credit facility, comprised of a (i) $143.0 million term loan, advanced in full on the closing date, (ii) a $30.0 million delayed draw term loan, and (iii) a $10.0 million revolving loan facility.

If any portion of the debt financing becomes unavailable on the terms and conditions described in or contemplated by the debt financing commitment, Parent has agreed to use its reasonable best efforts to arrange to obtain as promptly as practicable following the occurrence of such event, alternative financing in an amount sufficient to consummate the transactions contemplated by the merger agreement, which would not reasonably be expected to prevent, materially impede or materially delay the consummation of the debt financing or the transactions contemplated by the merger agreement.

NTS generally has agreed to, and to cause its subsidiaries to and its and their respective representatives to, use reasonable best efforts to, provide to Parent such cooperation (including with respect to timeliness) reasonably requested by Parent in connection with the debt financing, including providing reasonable assistance in the preparation of customary disclosure documents and customary representation letters reasonably required in connection with the debt financing.

77

Conditions to the Merger

The merger is subject to the satisfaction or waiver of various conditions, at or prior to the effective time, which include the following with respect to each party:

• the applicable waiting period, and any extension thereof, under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 shall have expired or been terminated;

• the merger agreement proposal is approved by NTS’s shareholders; and

• the absence of any injunction or other court order or legal or regulatory restraint that prevents the consummation of the merger or any law or order that prohibits or makes the merger illegal.

• (i) certain of the representations and warranties made by NTS contained in the merger agreement with respect to organization and good standing, subsidiaries, corporate power, authority and consents and capitalization are true and correct as of the date of the merger agreement and as of the closing date (or, if made as of an earlier date, as of such earlier date), subject in the case to certain representations and warranties relating to capitalization to any de minimis changes in amount or significance; and (ii) the remaining representations and warranties made by NTS contained in the merger agreement that are qualified by materiality or material adverse effect are true and correct (as so qualified) and the remaining representations and warranties made by NTS contained in the merger agreement that are not so qualified are true and correct in all material respects, in each case as of the date of the merger agreement and as of the closing date (or, if made as of an earlier date, as of such earlier date);

• NTS shall have performed, in all material respects, all obligations to be performed by it under the merger agreement on or prior to the effective time;

• Parent shall have received a certificate, dated the date of the closing of the merger and signed by any authorized representative of NTS, certifying as to the satisfaction of the preceding two conditions;

• there shall not be any pending action by any governmental authority or any other person which has a reasonable likelihood of success and, if successful, would result in a material adverse effect;

• since the date of the merger agreement, no event, change, circumstance, occurrence or effect shall have occurred that would or would reasonably be expected to have a material adverse effect.

NTS is not obligated to effect the merger unless the following conditions are satisfied or waived by NTS, at or prior to the effective time:

• (i) the representations and warranties of Parent and Merger Sub contained in the merger agreement that are qualified by materiality or Parent material adverse effect are true and correct (as so qualified) as of the date of the merger agreement and as of the closing date (or, if made as of an earlier date, as of such earlier date); and (ii) the representations and warranties of Parent and Merger Sub contained in the merger agreement that are not so qualified are true and correct in all material respects as of the date of the merger agreement and as of the closing date (or, if made as of an earlier date, as of such earlier date);

78

• Parent and Merger Sub shall have performed all obligations to be performed by them under the merger agreement on or prior to the effective time, except for obligations which, individually or in the aggregate, do not constitute a Parent material adverse effect; and

• NTS shall have received a certificate, dated the date of the closing of the merger, signed by any authorized representative of the Parent, certifying as to the satisfaction of the preceding two conditions.

Neither Parent, Merger Sub nor the Company may rely on the failure of any of the foregoing conditions to be satisfied if such failure was caused by such party’s breach of the merger agreement.

Termination of the Merger Agreement

In general, the merger agreement may be terminated at any time prior to the effective time of the merger, whether before or after the approval of the merger agreement and the merger by NTS shareholders, in the following ways:

• by mutual written consent of each of Parent and NTS;

• by either NTS or Parent if:

• the closing of the merger agreement shall not have been consummated by 5:00 p.m. Eastern time on February 15, 2014, referred to as the “end date,” except that such right to terminate is not available (i) to any party whose breach of any covenant or obligation under the merger agreement has been the proximate cause of, or resulted in, the failure of the closing to occur by the end date or (ii) to NTS if, at the time of such intended termination by NTS, either Parent or NTS could terminate the merger agreement because NTS shareholders shall have failed to approve the merger agreement proposal at the special meeting (after giving effect to all adjournments or postponements thereof);

• NTS shareholders shall have failed to approve the merger agreement proposal at the special meeting (after giving effect to all adjournments or postponements thereof); or

• (i) a court or other governmental authority shall have issued a judgment, order or taken other action enjoining or otherwise prohibiting any of the transactions contemplated in the merger agreement and such judgment, order or other action shall have become final and nonappealable or (ii) if there shall be any applicable law that makes consummation of the merger illegal or otherwise prohibits it, provided that such right to terminate is not available to any party that does not use reasonable best efforts to contest, appeal and remove such judgment, order or other action;

• by NTS if:

• Parent or Merger Sub has breached any representation, warranty, covenant or agreement contained in the merger agreement, or if any representation or warranty of Parent or Merger Sub shall have become untrue or incorrect, such that the closing conditions applicable to Parent or Merger Sub would not be satisfied, if occurring or continuing at the effective time, and such breach or failure to be true and correct is not cured by the earlier of the end date or 30 calendar days following receipt of written notice of such breach or failure (or such longer period to which NTS may agree), except that such right to terminate is not available to NTS if, at the time of such termination, there exists a material breach of any representation, warranty, covenant or agreement of NTS contained in the merger agreement;

• before receipt of the approval of the merger agreement and approval of the merger by NTS shareholders, (i) the NTS board of directors authorizes NTS to enter into a definitive acquisition agreement with respect to a superior proposal, (ii) NTS has complied with each of its obligations concerning the consideration of other acquisition proposals and (iii) NTS simultaneously enters into a definitive acquisition agreement with respect to such superior proposal and pays the $11.0 million termination fee to Parent; or

79

• all of the following three events have occurred: (i) NTS has satisfied (or Parent has waived) each of the conditions to Parent’s and Merger Sub’s obligations to consummate the merger, (ii) NTS has indicated in writing that it is ready, willing and able to consummate the merger on the second business day after the satisfaction or waiver of all conditions to the merger, and (iii) Parent and Merger Sub fail to consummate the merger within two business days of such date;

• NTS breaches or fails to perform any of its material obligations relating to the calling the special meeting of shareholders or the consideration of other acquisition proposals, or NTS or the NTS board of directors shall have formally resolved or publicly authorized or proposed to take any of the foregoing actions; or

• excluding breaches covered by the previous bullet point, NTS has breached any representation, warranty, covenant or agreement contained in the merger agreement, or if any representation or warranty of NTS shall have become untrue or incorrect, such that the closing conditions applicable to NTS would not be satisfied, if occurring or continuing at the effective time, and such breach or failure to be true and correct is not cured by the earlier of the end date or 30 calendar days following receipt of written notice of such breach or failure (or such longer period to which Parent may agree), except that such right to terminate is not available to Parent if, at the time of such termination, there exists a material breach of any representation, warranty, covenant or agreement of Parent contained in the merger agreement.

Effect of Termination of the Merger Agreement

Subject to the fee and expense payment provisions described below, in the event the merger agreement is terminated, the merger agreement will become void, and there will be no liability on the part of any party or any of their respective representatives, except:

• NTS or Parent may have liabilities as provided in the merger agreement relating to termination fees and expenses and legal expenses;

• subject to any limitation on liability provisions set forth in the merger agreement (see “The Merger Agreement — Limitation on Liability” below), no termination will relieve any party from any liability or damages resulting from a willful and material breach of any of its representations, warranties, covenants or agreements set forth in the merger agreement or for fraud; provided no party shall be liable for punitive damages.

The provisions in the merger agreement relating to merger expenses, public announcements, limitation on liability, notice of termination, notices, entire agreement, third party beneficiaries, governing law, submission to jurisdiction, limitation on suits against financing sources, assignment, binding on successors and assigns, waiver of jury trial, remedies, specific performance, severability, and interpretation and rules of construction will survive the termination of the merger agreement.

Fees and Expenses

Termination Fee.

NTS has agreed to pay Parent $11.0 million as a termination fee (less any expenses reimbursed under the conditions described in “The Merger Agreement — Expense Reimbursement”) if:

• all of the following three events have occurred: (i) an acquisition proposal, or intention to make an acquisition proposal, is made directly to NTS shareholders or is otherwise publicly disclosed or communicated to NTS or the NTS board of directors; (ii) the merger agreement is terminated by (A) Parent or NTS because of the failure of the closing to be consummated by the end date or because

80

of the failure of NTS’s shareholders to approve the merger agreement proposal, or (B) Parent because of a breach by NTS of any representation, warranty, covenant or agreement, or untruth or incorrectness of any representation or warranty made by NTS in the merger agreement; and (iii) within 12 months after the date of such termination NTS enters into an agreement in respect of any acquisition proposal (with each reference to “15%” in the definition of “acquisition proposal” deemed to be a reference to “50%”), or recommends or submits such an acquisition proposal to its shareholders for adoption, or a transaction in respect of such an acquisition proposal is consummated, which, in each case, need not be the same acquisition proposal that was made, disclosed or communicated prior to the termination of the merger agreement;

• Parent terminates the merger agreement due to (i) a change in the NTS board recommendation, (ii) NTS breaches or fails to perform any of its material obligations relating to the calling the special meeting of shareholders or the consideration of other acquisition proposals, or (iii) NTS or the NTS board of directors shall have formally resolved or publicly authorized or proposed to take any of the foregoing actions; or

• NTS terminates the merger agreement to enter into a definitive acquisition agreement with respect to a superior proposal.

Reverse Termination Fee.

Parent has agreed to pay NTS $19.0 million as a “reverse” termination fee if NTS terminates the merger agreement because (i) NTS has satisfied (or Parent has waived) each of the conditions to Parent’s and Merger Sub’s obligations to consummate the merger, (ii) NTS has indicated in writing that it is ready, willing and able to consummate the merger on the second business day after the satisfaction or waiver of all conditions applicable to it to consummate merger, and (iii) Parent and Merger Sub fail to consummate the merger within two business days of such date.

Expense Reimbursement.

If the merger agreement is terminated (i) by NTS or Parent because NTS shareholders shall have failed to approve the merger agreement proposal at the special meeting (after giving effect to all adjournments or postponements thereof), or (ii) by Parent because NTS shall have breached any representation, warranty, covenant or agreement in the merger agreement or because of any untruth or incorrectness in any representation or warranty of NTS in the merger agreement in a situation where the $11.0 million termination fee is not then payable to Parent, then NTS shall reimburse Parent and its affiliates for all of the reasonable out of pocket fees and expenses incurred by Parent or Merger Sub or on their behalf in connection with the merger agreement, up to a maximum of $7.5 million.

Limited Guaranty

Concurrently with the execution of the merger agreement, Aurora Equity Partners IV L.P. and Aurora Overseas Equity Partners IV L.P. (each, a “guarantor” and, collectively, the “guarantors”) entered into a Limited Guaranty with NTS pursuant to which, among other things, each such guarantor has unconditionally agreed to guarantee, on a several and not joint basis, subject to the terms and conditions set forth in the Limited Guaranty, the obligations of Parent to make any payments required to be made by Parent under the merger agreement (other than payment of the merger consideration), up to a maximum amount equal to the guarantors’ respective pro rata portions of the $19.0 million “reverse” termination fee described above. The guarantors are affiliates of Parent.

Specific Performance

Parent and Merger Sub may sue in equity for specific performance and/or to obtain an injunction to prevent breaches of the merger agreement by NTS and to enforce specifically the terms and provisions of the merger agreement.

81

NTS shall be entitled to specific performance only as follows:

• to cause Parent or Merger Sub to draw down the financing under the equity commitment letter, referred to as the “equity financing,” or to consummate the merger, but only if:

• all conditions to closing applicable to Parent and Merger Sub (other than those conditions which by their nature are to be satisfied at the closing) have been satisfied;

• Parent and Merger Sub have failed to complete the closing by the required date;

• the financing contemplated by the debt commitment letter, referred to as the “debt financing,” shall have been funded or shall fund at the closing (or, if substitute financing is obtained by Parent, such substitute financing shall have been funded or shall fund at closing) if the equity financing is funded at the closing; and

• NTS has irrevocably confirmed that if specific performance is granted and the equity financing and debt financing are funded, then the closing will occur; and

• to cause Parent to draw down the debt financing (or, if substitute financing is obtained, to draw down on such substitute financing), but only if:

• all conditions to closing applicable to Parent and Merger Sub(other than those conditions which by their nature are to be satisfied at the closing) have been satisfied;

• Parent and Merger Sub have failed to complete the closing by the required date;

• all of the conditions to the consummation of the debt financing provided by the debt financing commitment (or, if substitute financing is being used, pursuant to commitments with respect thereto) have been satisfied (other than those conditions which by their nature are to be satisfied at the closing); and

• NTS has irrevocably confirmed in writing to Parent that NTS is ready, willing and able to consummate the closing and if specific performance is granted and the equity financing and debt financing (or substitute financing) are funded, and Parent otherwise complies with its obligations under the merger agreement, then the closing will occur, except that Parent is not obligated to bring any action against Golub for breach of such party’s obligations under the debt commitment letter or any definitive financing agreement to enforce such party’s obligations.

Parent is under no obligation to bring an action against any of the parties to the debt commitment letter to fund the debt financing.

If the “reverse” termination fee has been paid by or on behalf of Parent, Merger Sub or the guarantors, then neither the Company nor any of its affiliates will be entitled to seek or obtain equitable relief, including specific performance to cause Parent to draw down on its financing commitments in the manner described above.

Limitation on Liability

Pursuant to the merger agreement, the liability of Parent, Merger Sub, their financing sources, the guarantors and each of their respective current, former or future affiliates, and current, former or future directors, officers, general or limited partners, shareholders, members, managers, controlling persons, employees, representatives and agents (collectively, the “Parent parties”) is limited as follows:

• no Parent party, other than Parent, Merger Sub or the guarantors may be liable for breach of the merger agreement or failure to consummate the merger;

• other than with respect to the limited right of the Company to seek specific performance under the circumstances described above, the maximum liability of Parent, Merger Sub and the guarantors for breach of the merger agreement or failure to consummate the merger or any other transaction or oral representation is the $19.0 million “reverse” termination fee; and

82

• upon payment of the “reverse” termination fee, no Parent party (including Parent, Merger Sub and the guarantors) will have any further liability to NTS or its shareholders.

Extension, Waiver and Amendment of the Merger Agreement

We and Parent may amend the merger agreement at any time prior to the effective time of the merger; however we and Parent may not amend certain provisions in a manner that impacts or is adverse in any respect to Parent’s financing sources without the prior written consent of Parent’s financing sources. In addition, after shareholder approval of the merger agreement has been obtained, no amendment may be made that requires shareholder approval under applicable law unless such approval is obtained.

At any time prior to the effective time of the merger, to the extent authorized or permitted by applicable law, either we or Parent may extend the time for the performance of any of the obligations or acts of the other party, waive any inaccuracies in the representations and warranties of the other party, and waive compliance by the other party with any of the agreements or conditions contained in the merger agreement. However, neither we nor Parent may waive certain provisions in the merger agreement in a manner that impacts or is adverse in any respect to Parent’s financing sources without the prior written consent of Parent’s financing sources. In addition, after shareholder approval of the merger agreement has been obtained, no waiver may be made that requires shareholder approval under applicable law unless such approval is obtained.

Vote Required for Approval and Board Recommendation

Approval of the merger agreement proposal requires the affirmative vote of the holders of a majority of the outstanding shares of NTS common stock entitled to vote at the special meeting. Abstentions and broker-non votes will have the effect of a vote “AGAINST” the merger agreement proposal.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE APPROVAL OF THE MERGER AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY, INCLUDING THE MERGER.

83

ADVISORY VOTE ON GOLDEN PARACHUTE COMPENSATION ARRANGEMENTS (PROPOSAL 2)

The Non-Binding Advisory Proposal

Section 14A of the Securities Exchange Act of 1934, which was enacted as part of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, requires companies to provide their shareholders with the opportunity to vote to approve, on an advisory non-binding basis, certain golden parachute compensation arrangements for its named executive officers. For smaller reporting companies such as NTS, named executive officers are the principal executive officer and the company’s next two most highly paid executive officers as of the end of the most recently completed fiscal year, based on total compensation determined under relevant regulations. Disclosure must also be provided for up to two additional individuals for whom disclosure would have been provided but for the fact that the individual was not serving as an executive officer of the smaller reporting company at the end of the last completed fiscal year.

Therefore, NTS is asking its shareholders to indicate their approval of golden parachute compensation arrangements and payments which the named executive officers will or may be eligible to receive in connection with the merger as disclosed in the section of this proxy statement entitled “The Merger — Interests of NTS Executive Officers and Directors in the Merger” beginning on page 52. These arrangements have previously constituted part of NTS’s overall compensation program for its named executive officers and have been previously disclosed to Company shareholders in NTS’s annual proxy statements and/or the Executive Compensation section of NTS’s annual reports on Form 10-K, including the most recently filed Form 10-K which was filed with the SEC on April 30, 2013. These historical arrangements were generally adopted and approved by NTS’s board of directors or the compensation committee of NTS’s board of directors, which is composed solely of non-management directors, and are believed to be reasonable and in line with marketplace norms. Estimated payments for these arrangements are specifically set forth in the table entitled “The Merger — Interests of NTS Executive Officers and Directors in the Merger” on page 52 of this proxy statement and the accompanying footnotes.

Accordingly, NTS is seeking approval of the following resolution at the special meeting of NTS’s shareholders to be held on [        ], 2013 (the “special meeting”):

“RESOLVED, that the shareholders of National Technical Systems, Inc. approve, solely on a nonbinding, advisory basis, the golden parachute compensation arrangements which may be paid to the named executive officers of National Technical Systems, Inc. in connection with the merger, as disclosed pursuant to Item 402(t) of Regulation S-K in National Technical Systems, Inc.’s proxy statement for the special meeting.”

Shareholders should be aware that, consistent with applicable law, this proposal regarding certain merger-related golden parachute compensation arrangements is merely an advisory vote which will not be binding on NTS, its board of directors, or Nest Parent, Inc. Further, the underlying compensation plans and arrangements are contractual in nature and are not, by their terms, subject to shareholder approval. Accordingly, regardless of the outcome of this advisory vote, if the merger is consummated, the named executive officers will remain eligible to receive the various golden parachute compensation payments in accordance with the terms and conditions applicable to those payments.

Vote Required for Approval and Board Recommendation

Approval of the non-binding advisory proposal regarding the golden parachute compensation arrangements requires the affirmative vote of a majority of the shares of common stock represented either in person or by proxy and voting upon the proposal, which shares voting affirmatively must also constitute at least a majority of the required quorum. Broker non-votes and abstentions have no effect on determining whether the affirmative vote constitutes a majority of the shares represented either in person or by proxy and voting upon the proposal. However, approval of the proposal also requires the affirmative vote of a majority of the shares necessary to constitute a quorum and, therefore, broker non-votes and abstentions could prevent the approval of the proposal because they do not count as affirmative votes.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE NON-BINDING ADVISORY PROPOSAL TO APPROVE THE GOLDEN PARACHUTE COMPENSATION ARRANGEMENTS DESCRIBED IN THIS PROXY STATEMENT.

84

ADJOURNMENT OF THE SPECIAL MEETING (PROPOSAL NO. 3)

The board of directors is asking NTS’s shareholders to vote on a proposal to adjourn the special meeting, if necessary or appropriate, in order to allow for the solicitation of additional proxies if there are insufficient votes at the time of the special meeting to approve the merger agreement proposal.

Even though a quorum may be present at the special meeting, it is possible that NTS may not have received sufficient votes to approve the merger agreement proposal by the time of the special meeting. In that event, NTS would need to adjourn the special meeting in order to solicit additional proxies. The adjournment proposal relates only to an adjournment of the special meeting for purposes of soliciting additional proxies to obtain the requisite shareholder vote to approve the merger agreement proposal.

To allow the proxies that have been received by NTS at the time of the special meeting to be voted for an adjournment if necessary, NTS is submitting this proposal to approve one or more adjournments, only under those circumstances, to you for consideration. If the new date, time and place are announced at the special meeting before the adjournment, NTS is not required to give notice of the adjourned meeting unless a new record date for the adjourned meeting is fixed, or unless the adjournment is for more than forty-five (45) days from the date set for the special meeting.

Subject to the terms of the merger agreement, the NTS board of directors retains full authority to the extent sent forth in our bylaws and California law to adjourn the special meeting for any other purpose, or to postpone the special meeting before it is convened, without the consent of any shareholders.

Vote Required for Approval and Board Recommendation

Approval of the adjournment proposal requires the affirmative vote of the majority of the shares of common stock represented either in person or by proxy, whether or not a quorum is present. Abstentions will have the same effect as a vote “AGAINST” this proposal. Broker non-votes will have the same effect as a vote “AGAINST” this proposal if the shares held by the broker are voted on one or both of the other proposals but not on this proposal, but broker non-votes will have no effect on the outcome of this proposal if the shares held by the broker are not voted on any of the proposals.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE APPROVAL OF THE ADJOURNMENT OF THE SPECIAL MEETING, IF NECESSARY OR APPROPRIATE, TO SOLICIT ADDITIONAL PROXIES.

85

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table presents information concerning the beneficial ownership of the shares of NTS’s common stock as of September 13, 2013 by:

• each person NTS known to be the beneficial owner of 5% or more of the outstanding shares of NTS’s common stock;

• each of NTS’s named executive officers;

• each of NTS’s directors; and

• all of NTS’s current executive officers and directors as a group.

Beneficial ownership is determined under the rules of the Securities and Exchange Commission Securities and Exchange Commission and generally includes voting or investment power over securities. Except in cases where community property laws apply or as indicated in the footnotes to this table, NTS believes that each shareholder identified in the table possesses sole voting and investment power over all shares of common stock shown as beneficially owned by the shareholder. The address for each of NTS’s directors and named executive officers is c/o National Technical Systems, Inc., 24007 Ventura Boulevard, Calabasas, California 91302.

The percentage of beneficial ownership is based on 11,714,729 shares of common stock outstanding on September 13, 2013. In accordance with Securities and Exchange Commission rules, shares of NTS’s common stock subject to options that are currently exercisable or exercisable within 60 days of September 13, 2013 are considered outstanding and beneficially owned by the person holding the options for the purpose of computing the percentage ownership of that person, but are not treated as outstanding for the purpose of computing the percentage ownership of any other person.

(a) Cancellation of Certain Company Common Stock. Each share of Company Common Stock (each, a “Common Share” and collectively, the “Common Shares”) that is held by Parent, Merger Sub or the Company

A-10

(as treasury stock or otherwise) or any of their respective direct or indirect Subsidiaries will automatically be cancelled and will cease to exist without any conversion thereof, and no consideration will be delivered in exchange therefor.

(b) Conversion of Company Common Stock. Each Common Share issued and outstanding immediately prior to the Effective Time (other than (i) Common Shares to be cancelled in accordance with Section 3.1(a), and (ii) Dissenting Shares) will be converted, subject to Section 3.2(g), into the right to receive in cash $23.00 per Common Share, payable to the holder thereof, without interest and less any applicable withholding taxes (the “Per Share Consideration”).

At the Effective Time, all Common Shares will no longer be outstanding and all Common Shares will automatically be cancelled and will cease to exist, and, subject to Section 3.3, each holder of a certificate formerly representing any such Common Shares (each, a “Certificate”) and book-entry shares which immediately prior to the Effective Time represented Common Shares (the “Book-Entry Shares”) will cease to have any rights with respect thereto, except only the right to receive the Merger Consideration allocable thereto in accordance with this Article III.

(d) Conversion of Merger Sub Capital Stock. Each share of common stock, no par value per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and become one newly and validly issued, fully paid and non-assessable share of common stock of the Surviving Corporation.

3.2 Surrender and Payment.

(a) Prior to the Effective Time, Parent, at its sole expense, shall appoint Computershare Trust Company N.A. or such other exchange agent as mutually agreed to in writing by the Company and Parent (the “Exchange Agent”) to act as the agent for the purpose of exchanging the Merger Consideration for: (i) the Certificates, or (ii) Book-Entry Shares. At the Closing, Parent shall deposit, or shall cause to be deposited, with the Exchange Agent, for the benefit of the holders of Common Shares, sufficient funds to pay the aggregate Merger Consideration that is payable in respect of all of the Common Shares represented by the Certificates and the Book-Entry Shares (the “Payment Fund”). The Payment Fund shall be invested for the benefit of the holders of Common Shares by the Exchange Agent as directed by Parent; provided, however, that: (A) no such investment or losses thereon shall affect the Merger Consideration payable to the holders of Common Shares represented by the Certificates and the Book-Entry Shares; and (B) such investments shall be in obligations of or guaranteed by the United States of America or any agency or instrumentality thereof and backed by the full faith and credit of the United States of America, in commercial paper obligations rated A-1 or P-1 or better by Moody’s Investors Service, Inc. or Standard & Poor’s Corporation, respectively, or in certificates of deposit, bank repurchase agreements or banker’s acceptances of commercial banks with capital exceeding $1 billion (based on the most recent financial statements of such bank that are then publicly available). If the Payment Fund is inadequate to pay the Merger Consideration that is payable in respect of all of the Common Shares represented by the Certificates and the Book-Entry Shares due to any loss in the Payment Fund or otherwise, Parent shall take all steps necessary to enable or cause the Surviving Corporation promptly (and in any case, within five (5) Business Days) to deposit in trust additional cash with the Exchange Agent sufficient to make all remaining payments required to be made pursuant to Section 3.1(b) hereof, and Parent and the Surviving Corporation shall in any event be liable for the payment thereof. Any net profit resulting from, or interest or income produced by, such investments shall be payable to the Surviving Corporation or Parent, and any amounts in excess of the amounts payable pursuant to Section 3.1 shall be promptly returned to the Surviving Corporation or Parent, in each case as directed by Parent. The Surviving Corporation shall pay all charges and expenses, including those of the Exchange Agent, incurred in connection with the exchange of Common Shares for the Merger Consideration. The Payment Fund shall not be used for any purpose other than to pay the Merger Consideration that is payable in respect of all of the Common Shares represented by the Certificates and the Book-Entry Shares. Promptly after the Effective Time (and in any case, within five (5) Business Days), Parent shall send, or shall cause the Exchange Agent to send, to each record holder of Common Shares at the Effective Time, a letter of transmittal in

A-11

a customary form to be mutually agreed to by the Company and Parent (the “Letter of Transmittal”) and instructions (which shall specify that the delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery of the Certificates or transfer of the Book-Entry Shares to the Exchange Agent) for use in such exchange.

(b) Each holder of Common Shares that have been converted into the right to receive the Merger Consideration shall be entitled to receive the Per Share Consideration allocable to such holder in respect of each Common Share held by such holder and represented by a Certificate or Book-Entry Share upon (i) surrender to the Exchange Agent of a Certificate, together with a duly completed and validly executed Letter of Transmittal and such other documents as may reasonably be requested by the Exchange Agent, or (ii) receipt of an “agent’s message” by the Exchange Agent (or such other evidence, if any, of transfer as the Exchange Agent may reasonably request) in the case of Book-Entry Shares. Until so surrendered or transferred, as the case may be, and subject to the terms set forth in Section 3.3, each such Certificate or Book-Entry Share, as applicable, shall represent after the Effective Time for all purposes only the right to receive the allocable Merger Consideration payable in respect thereof or the right to demand to be paid the “fair market value” of the Common Shares represented thereby as contemplated by Section 3.3. No interest shall be paid or accrued on the cash payable upon the surrender or transfer of any Certificate or Book-Entry Share.

(c) If any of the Per Share Consideration is to be paid to a Person other than the Person in whose name the surrendered Certificate or the transferred Book-Entry Share, as applicable, is registered, it shall be a condition to such payment that (i) such Certificate shall be properly endorsed or shall otherwise be in proper form for transfer or such Book-Entry Share shall be properly transferred, and (ii) the Person requesting such payment shall pay to the Exchange Agent any transfer or other Tax required as a result of such payment to a Person other than the registered holder of such Certificate or Book-Entry Share, as applicable, or establish to the reasonable satisfaction of the Exchange Agent that such Tax has been paid or is not payable.

(d) All Merger Consideration paid upon the surrender of Certificates or transfer of Book-Entry Shares in accordance with the terms hereof shall be deemed to have been paid in full satisfaction of all rights pertaining to the Common Shares formerly represented by such Certificate or Book-Entry Shares.

(e) The stock transfer books of the Company shall be closed immediately upon the Effective Time and thereafter there shall be no further registration of transfers of Common Shares on the stock transfer books of the Surviving Corporation. If, after the Effective Time, Certificates or Book-Entry Shares are presented to the Surviving Corporation, they shall be cancelled and exchanged for the Merger Consideration provided for, and in accordance with the procedures set forth, in this Article III.

(f) Any portion of the Merger Consideration made available to the Exchange Agent in respect of any Dissenting Shares shall be returned to Parent, upon demand.

(g) Any portion of the Payment Fund which remains undistributed to the holders of Common Shares for six (6) months after the Effective Time shall be delivered to the Surviving Corporation upon demand, and any holders of Common Shares who have not theretofore complied with this Article III shall thereafter look only to the Surviving Corporation for the Merger Consideration, without any interest thereon but subject to any applicable withholdings. If any Certificates or Book-Entry Shares shall not have been exchanged prior to two years after the Effective Time (or immediately prior to such earlier date on which the related Merger Consideration would otherwise escheat to or become the property of any Governmental Authority, any such Merger Consideration in respect thereof shall, to the extent permitted by Applicable Law, become the property of the Surviving Corporation, free and clear of all claims or interest of any Person previously entitled thereto.

(h) None of Parent, the Company or the Surviving Corporation shall be liable to any holder of Common Shares for any cash from the Payment Fund delivered to a public official pursuant to any abandoned property, escheat or similar Applicable Law.

A-12

(i) No dividends or other distributions with respect to capital stock of the Surviving Corporation with a record date on or after the Effective Time shall be paid to the holder of any unsurrendered Certificates.

3.3 Dissenting Shares. Notwithstanding any provision of this Agreement to the contrary, including Section 3.1, Common Shares which were outstanding on the date for the determination of shareholders entitled to vote on the Merger (other than Common Shares cancelled in accordance with Section 3.1(a)), which were not voted in favor of the Merger, and the holders of which (i) have demanded that the Company purchase such Common Shares at their fair market value in accordance with Section 1301 of CGCL (ii) have submitted such Common Shares for endorsement in accordance with Section 1302 of CGCL and (iii) have not otherwise failed to perfect or shall not have effectively withdrawn or lost their rights to be entitled to require the corporation to purchase their shares under CGCL (such Common Shares being referred to collectively as the “Dissenting Shares”) shall not be converted into a right to receive the Merger Consideration allocable to such Dissenting Shares, but instead shall be entitled to only such rights as are granted by Section 1300 et. seq. of the CGCL; provided, however, that if, after the Effective Time, such holder fails to perfect, withdraws or loses such holder’s right to appraisal pursuant to Section 1300 et. seq. of the CGCL or if a court of competent jurisdiction shall determine that such holder is not entitled to the relief provided by Section 1300 et. seq. of the CGCL, such Common Shares shall be treated as if they had been converted as of the Effective Time into the right to receive the Merger Consideration allocable thereto in accordance with Section 3.1(b), without interest thereon but subject to any applicable withholdings, upon surrender of such Certificate formerly representing such Common Share or transfer of such Book-Entry Share, as the case may be. The Company shall provide Parent prompt written notice (and in any event within three (3) Business Days) of any demands received by the Company for appraisal of Common Shares, any withdrawal of any such demand and any other demand, notice or instrument delivered to the Company prior to the Effective Time pursuant to the CGCL that relates to such demand; provided, however, that commencing ten (10) Business Days prior to the Shareholders Meeting, the Company shall provide Parent with the aforementioned written notice within two (2) days of receipt by the Company of any such demand (or demand withdrawal), notice or instrument and in any event the Company shall provide to Parent all such demands, withdrawals, notices and/or instruments that it is in receipt of on the day prior to the Shareholders Meeting and for which notice has not already been provided to Parent, to Parent on the day prior to the Shareholders Meeting and shall provide notice of any such demand, withdrawal, notice or instrument received on the day of the Shareholders Meeting to Parent immediately following receipt. Parent shall have the opportunity and right to direct all negotiations, petitions and proceedings with respect to any such demands. Prior to the Effective Time, the Company shall not, without the prior written consent of Parent (which may be given or withheld in Parent’s sole discretion), make any payment with respect to, or settle or offer to settle, any such demands, or agree to do any of the foregoing.

3.4 Adjustments. Without limiting the other provisions of this Agreement, if, at any time during the period between the Agreement Date and the Effective Time, any change in the outstanding shares of capital stock of the Company shall occur (other than the issuance of additional shares of capital stock of the Company as expressly permitted by this Agreement) by reason of any reclassification, recapitalization, stock split (including reverse stock split) or combination, exchange or readjustment of shares, or any stock dividend or distribution paid in stock, the Per Share Consideration and any other amounts payable pursuant to this Agreement shall be appropriately adjusted to reflect such reclassification, recapitalization, stock split (including reverse stock split) or combination, exchange or readjustment of shares, or any stock dividend or distribution paid in stock and to provide to the holders of Common Shares the same economic effect as contemplated by this Agreement prior to such action; provided, however, that nothing in this Section 3.4 shall be construed to permit the Company to take any action with respect to its securities that is prohibited by the terms of this Agreement.

3.5 Withholding Rights. Notwithstanding anything herein to the contrary, each of the Exchange Agent, Parent, Merger Sub and the Surviving Corporation shall be entitled to deduct and withhold, or cause to be deducted and withheld, from the consideration otherwise payable to any Person pursuant to this Article III such amounts as may be required to be deducted and withheld with respect to the making of such payment under any

A-13

provision of any applicable Tax law. To the extent that amounts are so deducted and withheld, such amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of whom such deduction and withholding was made.

3.6 Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit, in form and substance reasonably acceptable to Parent, of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent or the Exchange Agent, the posting by such Person of a bond in such amount as Parent or the Exchange Agent may determine is reasonably necessary as indemnity against any claim that may be made against it or the Surviving Corporation with respect to such Certificate, the Exchange Agent will issue, in exchange for such lost, stolen or destroyed Certificate, the allocable Merger Consideration to be paid in respect of the Common Shares formerly represented by such Certificate as contemplated under this Article III, without any interest thereon but subject to any applicable withholdings.

3.7 Treatment of Equity Awards.

(a) The Company shall take all requisite action so that, immediately prior to the Effective Time, each option to acquire shares of Company Common Stock, restricted shares of Company Common Stock, and restricted stock units set forth on Section 3.7(a) of the Company Disclosure Schedule then outstanding and unvested and/or not exercisable (irrespective of any time- or performance-based condition or other contingency) (each, an “Unvested Equity Award”), shall become fully vested and exercisable. At the Effective Time, each Equity Award not previously exercised shall be, by virtue of the Merger and without any action on the part of Parent or Merger Sub, cancelled and converted into solely the right to receive from Parent and the Surviving Corporation, as promptly as reasonably practicable after the Effective Time (and in any case, within five (5) Business Days), an amount in cash, without interest, equal to the product of (i) the excess, if any, of the Per Share Consideration over any applicable exercise price per share of such Equity Award, and (ii) the number of shares of Company Common Stock for which such Equity Award is exercisable, without interest and subject to applicable withholdings, including for income and employment Taxes (with the aggregate amount rounded down to the nearest whole cent); provided that if the exercise price per share of any such Equity Award is equal to or greater than the Per Share Consideration, then such Equity Award shall be canceled without any cash payment being made in respect thereof.

(b) At or prior to the Effective Time, the Company, the Company Board and the Company’s Compensation Committee shall adopt such resolutions and take such other actions, which may, to the extent required under the terms of the applicable Equity Awards, include obtaining consents of employees, officers, directors and any other holders of Equity Awards, as may be necessary to effectuate the provisions of Section 3.7(a).

(b) Notwithstanding Section 6.5(a), nothing contained in this Agreement shall prevent the Company or the Company Board from (i) contacting a Person who has made, or proposes to make an Acquisition Proposal and to whom the Company is permitted to provide non-public information pursuant to Section 6.5(c) solely to request clarifications of the terms and conditions of such Acquisition Proposal, or (ii) complying with its disclosure obligations under Exchange Rules 14d-9 and 14e-2(a) with regard to an Acquisition Proposal; provided, however, that any such disclosure (other than a “stop, look and listen” communication or similar communication of the type contemplated by Exchange Act Rule 14d-9(f)) shall be deemed to be a Change in Board Recommendation unless the Company Board reaffirms the Board Recommendation in such disclosure.

(c) Notwithstanding any provisions of Section 6.5(a) to the contrary, nothing contained in this Section 6.5 shall prevent the Company or any of its Subsidiaries, or the Company Board from, at any time prior to obtaining the Requisite Company Vote, (x) providing information with respect to the Company and its Subsidiaries to a Person making an Acquisition Proposal after the Agreement Date, in response to a request therefor; provided, however, that any non-public information provided or made available to such Person or its Representatives receiving such information, whether before or after such Person’s making of an Acquisition Proposal, shall have been previously provided or made available to Parent or shall be provided or made available to Parent prior to or substantially concurrently with the time it is provided or made available to such Person; provided, further that the Company Board receives from such Person, prior to providing any information or engaging in any negotiations or discussions, (i) a confidentiality agreement with the Company containing terms substantially similar to, and no less favorable to the Company than those set forth in the NDA taken as a whole (provided, that such confidentiality agreement need not include a standstill provision), and (ii) evidence reasonably satisfactory to the Company Board, which demonstrates the financial capability of such Person to consummate the Acquisition Proposal; provided, further that prior to taking any action described in clause (x) above or clause (y) below, (A) the Company Board shall have determined in good faith, after consultation with outside legal counsel, that failure to take the actions referred to in clause (x) above or clause (y) below, as applicable, would be inconsistent with the fiduciary duties of the Company Board to the Company Shareholders under Applicable Law, (B) the Company Board shall have determined in good faith, based on the information then available and upon the recommendation of the Special Committee (after consultation with the Special Committee’s independent financial advisor and outside legal counsel), that such Acquisition Proposal constitutes

A-42

a Superior Proposal, and (C) such Acquisition Proposal is bona fide, written and not a result of a breach or violation of this Section 6.5, or (y) engaging in any negotiations or discussions with the Person making an Acquisition Proposal described in and satisfying the requirements of clause (x) regarding such Acquisition Proposal. The Company shall promptly (and in no event later than two (2) Business Days after receipt by the Company) advise Parent in writing of any inquiry or proposal or offer related to an Acquisition Proposal or any request for nonpublic information relating to the Company or its Subsidiaries other than requests that are not reasonably expected to be related to an Acquisition Proposal (including the identity of the Person making or submitting such Acquisition Proposal or request, and the terms thereof) that is made or submitted by any Person prior to the Effective Time.

(d) Except as expressly permitted by Section 6.5(e), neither the Company Board nor any committee thereof shall (i) withhold, withdraw, modify or qualify, or propose publicly to withhold, withdraw, modify or qualify, in a manner adverse to Parent or Merger Sub, the approval of this Agreement and the Merger or the recommendation of the Company Board in favor thereof (the “Board Recommendation”) or take any action or make any statement in connection with the Shareholders Meeting inconsistent with such approval or Board Recommendation, (ii) adopt, approve, endorse, recommend, or otherwise declare advisable or propose to adopt, approve, endorse, recommend, or otherwise declare advisable, publicly or otherwise, any Acquisition Proposal, (iii) fail to publicly reaffirm the Board Recommendation within three (3) Business Days after Parent or Merger Sub so requests in writing, (iv) fail to recommend against any Acquisition Proposal within five (5) Business Days (other than an Acquisition Proposal described in clause (v) next below for which the Company shall have ten (10) Business Days), (v) fail to recommend, in a Solicitation/Recommendation Statement on Schedule 14D-9, against any Acquisition Proposal subject to Regulation 14D under the Exchange Act, within ten (10) Business Days after the commencement of any such Acquisition Proposal, (vi) fail to include the Board Recommendation in the Company Proxy Statement, (vii) cause or permit the Company or any of its Subsidiaries to enter into any letter of intent, memorandum of understanding, agreement in principle or similar document or Contract constituting or relating to any Acquisition Proposal (other than a confidentiality agreement entered into in accordance with, and meeting the requirements of, Section 6.5(c)), (viii) make any other public statement that is inconsistent with the Board Recommendation, or (ix) resolve, agree or propose to take any such actions (any action described in clauses (i) through (ix), and the action expressly referred to in Section 6.5(b), a “Change in Board Recommendation”).

(e) Notwithstanding anything to the contrary set forth in this Agreement, at any time prior to obtaining the Requisite Company Vote, if the Company Board determines in good faith after consultation with outside legal counsel that the failure to do so would be inconsistent with the fiduciary duties of the Company Board to the Company Shareholders under Applicable Law, taking into account all adjustments to the terms of this Agreement that may be offered by Parent pursuant to this Section 6.5 (x) the Company Board may effect a Change in Board Recommendation in response to either (1) a Superior Proposal or (2) an Intervening Event or (y) solely if the Company has received an unsolicited bona fide written Acquisition Proposal from any Person that is not withdrawn and that the Company Board concludes in good faith constitutes a Superior Proposal and did not otherwise result from a breach of this Section 6.5, terminate this Agreement pursuant to Section 9.3(b) and concurrently enter into a binding definitive acquisition agreement with respect to such Superior Proposal;

provided, however, that the Company may take the action set forth in the preceding clause (y) or make a Change in Board Recommendation in response to a Superior Proposal if and only if:

(i) the Company shall have complied with each of its obligations under this Section 6.5 relating to such Change in Board Recommendation, or resulting in the Acquisition Proposal that led to such Superior Proposal;

(ii) (A) the Company shall have provided written notice to Parent at least five (5) Business Days in advance (the “Notice Period”), to the effect that the Company Board has received an unsolicited bona fide written Acquisition Proposal that is not withdrawn and that the Company Board has concluded in good faith constitutes a Superior Proposal and, absent any revision to the terms and conditions of this Agreement,

A-43

the Company Board has resolved to terminate this Agreement pursuant to this Section 6.5(e), which notice shall specify the basis and reasons for such resolution, including the identity of the Person or group of Persons making the Superior Proposal and the terms and conditions thereof, and shall have contemporaneously furnished to Parent a copy of the proposed definitive acquisition agreement and any other relevant transaction documentation; (B) prior to effecting such termination of this Agreement, (1) the Company shall, and shall cause its financial and legal advisors to, during the Notice Period, negotiate with Parent in good faith (to the extent requested by Parent) regarding any revisions to the terms of the transactions contemplated by this Agreement proposed by Parent, and (2) if Parent makes a proposal during the Notice Period, at the end of such Notice Period, the Company Board, after taking into consideration the adjusted terms and conditions of this Agreement as proposed by Parent, still determines in good faith, upon the recommendation of the Special Committee (after consultation with outside legal counsel and the Special Committee’s financial advisor), that the Acquisition Proposal continues to constitute a Superior Proposal and, after consultation with outside legal counsel, that the failure to terminate this Agreement would be inconsistent with the fiduciary duties of the Company Board to the Company Shareholders under Applicable Law; provided that, in the event of any revisions to the financial terms or any other material terms of such Superior Proposal, the Company shall be required to deliver a new written notice to Parent and to comply with the requirements of this Section 6.5 (including this Section 6.5(e)) with respect to such new written notice, and there shall be a new Notice Period; and

(iii) in the case of any action as contemplated by clause (y) of this Section 6.5(e) above, the Company shall have validly terminated this Agreement in accordance with Section 9.3(b), including the payment of the Termination Fee (as defined below) to Parent in accordance with Section 9.6(a);

(ii) the Company keeps Parent reasonably informed of developments with respect to such Intervening Events;

(iii) the Company notifies Parent in writing at least five (5) Business Days before making such a Change in Board Recommendation with respect to such Intervening Event of its intention to do so and specifies the reasons therefor;

(iv) if Parent makes a proposal during such five (5) Business Day period to adjust the terms and conditions of this Agreement, the Company Board, after taking into consideration the adjusted terms and conditions of this Agreement as proposed by Parent, continues to determine in good faith, after consultation with outside counsel, that the failure to make such Change in Board Recommendation would result in a breach of the fiduciary duties of the Company Board to the Company Shareholders under Applicable Law; and

(v) during such five (5) Business Day period, the Company shall, and shall cause its financial and legal advisors to negotiate with Parent in good faith (to the extent requested by Parent) regarding any revisions to the terms of the transaction contemplated by this Agreement as proposed by Parent.

(f) The Company agrees that it shall (i) immediately cease and cause to be terminated any existing investigation, discussions or negotiations with any Person (other than Parent and Merger Sub) with respect to any Acquisition Proposal or potential Acquisition Proposal, (ii) request as promptly as practicable after the execution of this Agreement (but in any event on the day after the Agreement Date) the prompt return or destruction of all confidential information previously furnished with respect to any Acquisition Proposal or potential Acquisition Proposal, and (iii) deliver as promptly as practicable after the execution of this Agreement (but in any event on the day after the Agreement Date) a written notice to each such Person to the effect that the Company is ending all discussions and negotiations with such Person with respect to any Acquisition Proposal, effective on the Agreement Date.

(g) Subject to the terms of any applicable confidentiality agreement, the Company agrees that it shall promptly (and, in any event, within two (2) Business Days of receipt) notify Parent of (i) the receipt of any Acquisition Proposal or any indication by any Person that it is considering making an Acquisition Proposal, (ii) any request for non-public information relating to the Company or the Subsidiaries, other than requests for information not reasonably expected to be related to an Acquisition Proposal, and (iii) any inquiry, offer or request for discussions or negotiations regarding an Acquisition Proposal or that is reasonably likely to lead to an Acquisition Proposal, in each case including, with such notice, the identity of the Person or group of Persons making such proposal, offer, request, indication or inquiry, a copy of any written proposal, offer or draft agreement provided by such Person and the material terms and conditions of any proposals or offers, and thereafter shall keep Parent promptly and reasonably informed of the status, details and terms of any such proposals or offers (including any amendments thereto) and the status of any such discussions or negotiations (including of any amendment, modification, development, discussion or negotiation), including furnishing copies of any written inquiries, correspondence and draft documentation, and written summaries of any material oral inquiries or discussions. Without limiting the generality of the foregoing, the Company shall promptly notify Parent orally and in writing if it determines to begin providing information or to engage in discussions or negotiations concerning an Acquisition Proposal permitted pursuant to this Section 6.5 and shall in no event begin providing such information or engaging in such discussions or negotiations prior to providing such notice.

(h) The Company will not terminate, waive, amend, release or modify any provision of any existing confidentiality agreement or standstill agreement to which the Company or any of its Subsidiaries is a party with respect to any Acquisition Proposal or potential Acquisition Proposal, will enforce the terms thereof, and will not permit any counterparty to any such Contract to deviate from compliance with the terms thereof; provided, however, that to the extent any confidentiality or standstill agreement to which the Company or any of its Subsidiaries is a party contains a provision that prohibits the counterparty to such agreement from requesting a waiver to a standstill, the Company shall be permitted to waive its rights with respect to such prohibition. The Company shall promptly notify Parent of any breach of any existing confidentiality agreement by the counterparty thereto.

6.6 Preparation of Company Proxy Statement; Approval of Company Shareholders.

(a) As promptly as practicable following the date on which the Company Proxy Statement is cleared by the SEC for mailing to the Company Shareholders, the Company shall, in accordance with Applicable Law and the Company Charter and the Company Bylaws, duly call, give notice of, convene and hold a meeting of the Company Shareholders to consider and vote upon approval of this Agreement (the “Shareholders Meeting”); provided, however, that in no event shall such meeting be held later than 75 calendar days following the date on which the Company Proxy Statement is cleared by the SEC for mailing, and any adjournments or postponements of the Shareholders Meeting shall require the prior written consent of Parent (which shall not be unreasonably withheld, conditioned or delayed) other than in the case the Company is required to allow reasonable additional time for the filing and mailing of any supplemental or amended disclosure which is required by court order or under Applicable Law and for such supplemental or amended disclosure to be disseminated and reviewed by the Company Shareholders prior to the Shareholders Meeting. Except in the case of a Change in Board Recommendation specifically permitted by Section 6.5(e), the Company, through the Company Board, shall (i) solicit from the holders of Company Common Stock proxies in favor of the adoption of this Agreement in accordance with the CGCL, (ii) recommend to the Company Shareholders that they adopt this Agreement and the transactions contemplated hereby, (iii) include such recommendation in the Company Proxy Statement.

Once the Company has established a record date for the Shareholders Meeting, the Company shall not change such record date or establish a different record date for the

A-45

Shareholders Meeting without the prior written consent of Parent (which shall not be unreasonably withheld, conditioned or delayed), unless required to do so by Applicable Law or the Company Bylaws. The Company shall use all reasonable efforts to have the Company Proxy Statement cleared by the SEC as promptly as practicable after the filing thereof.

The Company shall provide Parent, Merger Sub and their counsel a reasonable opportunity to review and comment on the Company’s proposed responses to any comments to the Company Proxy Statement from the SEC or its Staff prior to the Company responding to any such comments and shall give due consideration to all reasonable additions, deletions or changes suggested thereto by Parent, Merger Sub and their counsel. Parent shall cooperate fully with the Company in the preparation of the Company Proxy Statement or any amendment or supplement thereto and shall furnish the Company, promptly upon the Company’s request, all information relating to Parent and Merger Sub reasonably requested by the Company for inclusion in, or otherwise in respect of, the Company Proxy Statement. The Company shall provide Parent and Merger Sub and their counsel a reasonable opportunity to review and comment on the Company Proxy Statement (including any amendment or supplement thereto) and all other materials used in connection with the Merger that (i) constitute “proxy materials” or “solicitation materials” as those terms are used in Rules 14a-1 through 14a-17 promulgated under the Exchange Act or (ii) are otherwise used for the “solicitation” of “proxies” as those terms are defined in Rule 14a-1 promulgated under the Exchange Act, in each case prior to the filing thereof with the SEC and the mailing/dissemination thereof to the Company Shareholders, and shall give due consideration to all reasonable additions, deletions or changes suggested thereto by Parent, Merger Sub and their counsel.

(d) Subject only to a Change in Board Recommendation in compliance with Section 6.5(d), the Board Recommendation shall be included in the Company Proxy Statement.

6.7 Litigation. The Company shall notify Parent in writing promptly but in any event no later than three (3) Business Days after learning of any material Action or mediation by or before any court, arbitrator or arbitration panel, board or governmental agency, initiated by or against it, or known by the Company to be threatened against the Company or any of its officers or directors in their capacity as such.

6.8 Access to Information. The Company shall, and shall cause each of its Subsidiaries to, afford Parent, Merger Sub and their respective Representatives access during regular business hours, so long as 24 hour advance notice is provided, to all of their respective files, books, records, Contracts, personnel, properties, assets and offices of the Company, including without limitation any and all information relating to the Company’s taxes, Contracts, Liabilities, financial condition and real, personal and intangible property (which such access shall expressly exclude the right for Parent, Merger Sub and their respective Representatives to conduct environmental testing of the Company’s and its Subsidiaries’ properties), and the Company shall, and shall cause each of its Subsidiaries to, furnish promptly to Parent: (a) a copy of each report, schedule, registration statement

No investigation pursuant to this Section 6.8 or information provided, made available or delivered to Parent pursuant to this Agreement shall affect any of the representations, warranties, covenants, rights or remedies, or the conditions to the obligations of, the parties hereunder.

6.9 Company Cooperation with Debt Financing Efforts. From the Agreement Date through the Closing Date or the termination of this Agreement, the Company shall, and shall cause its Subsidiaries to and its and their respective Representatives to, use reasonable best efforts to, provide to Parent such cooperation (including with respect to timeliness) reasonably requested by Parent in connection with the Debt Financing (provided that such requested cooperation is consistent with Applicable Law and does not unreasonably interfere with the operations of the Company or any of its Subsidiaries) including providing reasonable assistance in the preparation of customary disclosure documents and customary representation letters reasonably required in connection with the Debt Financing. The Company hereby consents to the use of its and its Subsidiary’s names, logos and trademarks solely in connection with the Debt Financing. Neither the Company nor the Subsidiaries shall be required, under the provisions of this Section 6.9 or otherwise in connection with the Debt Financing, (x) to pay any commitment or other similar fee prior to the Closing Date that is not advanced or substantially simultaneously reimbursed by Parent or (y) to incur any out of pocket cost or expense unless such expense is reimbursed by Parent on the earlier of the Closing Date or termination of this Agreement in accordance with Article IX. Nothing contained in this Section 6.9 shall require the Company or its Subsidiaries to be an issuer or other obligor with respect to the Debt Financing or to authorize or approve the Debt Financing prior to the Closing. All material, non-public information regarding the Company and the Subsidiaries provided to Parent or its Representatives pursuant to this Section 6.9 shall be kept confidential by them in accordance with the NDA except for disclosure to potential lenders and investors as required in connection with the Debt Financing subject to customary confidentiality protections.

(d) Notwithstanding any other provision in this Agreement to the contrary, nothing in this Section 7.2 will require, or be construed to require, Parent, Merger Sub or any of their respective Affiliates to agree or proffer to (i) sell, hold separate, divest, discontinue or limit, before or after the Effective Time, any assets, businesses or interest in any assets or businesses of Parent or any of its Affiliates, or assuming the consummation of the Merger, the Surviving Corporation or any of its Affiliates, (ii) limit in any manner whatsoever or not to exercise any rights of ownership of any securities (including the Common Shares), or (iii) enter into any agreement that in any way limits the ownership or operation of any business of Parent, the Company, the Surviving Corporation or any of their respective Affiliates.

7.3 Parent Financing.

(a) Debt Financing. Parent shall, and shall cause Merger Sub to, use its reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable to arrange and obtain the Debt Financing on the terms and conditions described in the Debt Financing Commitments, including using reasonable best efforts to (i) maintain in effect the Debt Financing Commitments, (ii) satisfy on a timely basis all conditions applicable to Parent or Merger Sub to obtaining the Debt Financing (including by consummating the Equity Financing at or prior to Closing), (iii) enter into definitive agreements with respect thereto on terms and conditions contained in the Debt Financing Commitments or consistent in all material respects with the Debt Financing Commitments, or on other terms that would not materially and adversely impact the ability of Parent to timely consummate the transactions contemplated hereby, and (iv) draw down on the Debt Financing if the conditions to the availability of the Debt Financing have been satisfied or waived. Parent shall not, and shall cause Merger Sub to not, agree to or permit any amendment, supplement or other modification of, or waive any of its rights under, any Debt Financing Commitment or any definitive agreements related to the Debt Financing, if such amendment, supplement, modification or waiver would (A) reduce the aggregate amount of the Debt Financing, or (B) impose new or additional conditions, or otherwise amend, modify or expand any conditions to the receipt of the Debt Financing, in the case of either clause (A) or

A-49

(B) above in a manner that would reasonably be expected to (1) materially delay or prevent the Closing Date, (2) make the funding of the Debt Financing (or the satisfaction of the conditions to obtaining the Debt Financing) materially less likely to occur or (C) materially adversely impact the ability of Parent or Merger Sub to enforce their rights against the other parties to the Debt Financing Commitments or the definitive agreements with respect thereto, the ability of Parent and Merger Sub to consummate the Closing or the likelihood of consummation of the Closing, in each case, without the Company’s prior written consent; provided, however, that Parent and Merger Sub may amend the Debt Financing Commitments or any definitive agreements related to the Debt Financing to add lenders, lead arrangers, bookrunners, syndication agents, other funding sources, additional equity financiers or similar entities who had not executed the Debt Financing Commitments as of the Agreement Date. Upon any such amendment, supplement or modification of the Debt Financing Commitments in accordance with this Section 7.3(a), Parent shall provide a copy thereof to the Company and the term “Debt Financing Commitments” shall mean the Debt Financing Commitments as so amended, supplemented or modified. Parent shall keep the Company reasonably apprised of developments relating to the Debt Financing and will provide prompt notice of any material breach or default by any party to the Debt Financing Commitment of which Parent becomes aware or any written communication from any Person with respect to any actual or purported material breach, termination or repudiation by any party to the Debt Financing Commitment.

(b) Substitute Financing. As an alternative to the Debt Financing, Parent and Merger Sub may obtain substitute financing consistent with the section in the Debt Financing Commitments entitled “Alternative Financing Structure” (the “Substitute Financing”) so long as the replacement of the Debt Financing Commitments with commitments for the Substitute Financing (the “Substitute Financing Commitments”) would not be adverse in any material respect to the Company, taking the Debt Financing Commitments and the Substitute Financing Commitments as a whole. In the event the Debt Financing is so replaced, the term “Debt Financing Commitments” shall mean the Substitute Financing Commitments and the term “Debt Financing” shall mean the “Substitute Financing”.

(c) Alternative Financing. In the event all or any portion of the Debt Financing becomes unavailable on the terms and conditions described in or contemplated by the Debt Financing Commitments for any reason, Parent shall use its reasonable best efforts to arrange to obtain, as promptly as practicable following the occurrence of such event, alternative financing (the “Alternative Financing”) in an amount sufficient to consummate the transactions contemplated by this Agreement which would not reasonably be expected to prevent, materially impede or materially delay the consummation of the Debt Financing or the transactions contemplated by this Agreement. To the extent the Debt Financing is so replaced, the term “Debt Financing Commitments” shall mean the Debt Financing Commitments, if any, and the commitments for the Alternative Financing, together, and the term “Debt Financing” shall mean the Debt Financing, if any, and the Alternative Financing, in the aggregate.

7.4 Indemnification of Company Directors and Officers.

(a) If the Merger is consummated, then until the sixth anniversary of the Effective Time, Parent shall cause the Surviving Corporation to fulfill and honor in all respects the obligations of the Company to its current and former directors and officers (the “Company Indemnified Parties”) pursuant to any indemnification provisions under the Company’s Charter, Company Bylaws and any indemnification agreement which has been provided to Parent between the Company and such Company Indemnified Parties, as in effect on the Agreement Date (the “Company Indemnification Provisions”), with respect to claims arising out of acts or omissions occurring prior to the Effective Time. Any claims for indemnification made under this Section 7.4(a) on or prior to the sixth anniversary of the Effective Time shall survive such anniversary until the final resolution thereof.

(b) This Section 7.4 shall survive the consummation of the Merger, is intended to benefit each Company Indemnified Party, shall be binding on all successors and assigns of the Surviving Corporation and Parent, and, notwithstanding Section 10.12 shall be enforceable by the Company Indemnified Parties.

A-50

(c) Prior to the Effective Time, Parent shall purchase directors’ and officers’ liability insurance coverage for a period of six (6) years after the Effective Time for the Company’s current directors and officers for acts or omissions occurring prior to the Effective Time, the material terms of which, including coverage and amount, are no less favorable in any material respect to such directors and officers than the Company’s existing policies as of the Agreement Date and provided further, that in no event shall Parent be required to pay annual premiums for insurance under this Section 7.4(c) in excess of 200% of the amount of the annual premiums paid by the Company for fiscal year 2013 for such purpose (which fiscal year 2013 premiums are hereby represented and warranted by the Company to be as set forth in Section 7.4(c) of the Company Disclosure Schedule), it being understood that Parent shall nevertheless be obligated to provide as much coverage as may be obtained for such 200% amount.

7.5 Employees; Benefit Plans.

(a) During the period commencing at the Effective Time and ending on the date which is twelve (12) months after the Effective Time (or if earlier, the date of the employee’s termination of employment with Parent and its Subsidiaries), Parent shall cause the Surviving Corporation and each of its Subsidiaries, as applicable, to provide the employees of the Company and its Subsidiaries who remain employed immediately after the Effective Time (collectively, the “Company Continuing Employees”) with base salary and target cash bonus opportunities (but not, for the avoidance of doubt, equity-based compensation) that are, in the aggregate, no less favorable to the base salary and target cash bonus opportunities provided by the Company and its Subsidiaries on the Agreement Date. The employees covered by this provision will remain at-will employees in all respects. Nothing contained in this Agreement shall confer upon any employee any right with respect to continued employment by Parent or Surviving Corporation, nor shall anything herein interfere with the right of Parent or Surviving Corporation to terminate the employment of any employee (including any Company Continuing Employee) at any time, with or without cause, following the effective date of his or her employment with Parent or Surviving Corporation.

(b) With respect to any employee benefit plan, program, policy or arrangement that is sponsored, maintained or contributed to by Parent or any of its Subsidiaries (collectively, “Parent Benefit Plans”) in which any Company Continuing Employees are or may become eligible to participate in on or following the Effective Time, Parent shall use commercially reasonable efforts to, or shall cause the Surviving Corporation to, to the extent permitted by the terms of the applicable employee benefit plans, programs, policies, or arrangements, recognize all service of the Company Continuing Employees with the Company or any of its Subsidiaries, as the case may be, as if such service were with Parent or any of its Subsidiaries, for purposes of eligibility to participate, vesting and benefit levels based on seniority; provided, that, such service shall not be recognized (i) for benefit accrual purposes under any Parent Benefit Plan that is a defined benefit pension plan, or (ii) to the extent that such recognition would result in a duplication of benefits.

(c) Nothing contained in this Agreement shall create any third party beneficiary rights in any Company Continuing Employee or other employee of the Company, or any beneficiary or dependents thereof, with respect to any right of employment (including, without limitation, the compensation, terms and conditions of employment and benefits) or any other legal or equitable right, benefit or remedy of any nature. Nothing in this Agreement, expressed or implied, shall amend, or be deemed to amend, any benefit plan of Parent or the Surviving Corporation or any Benefit Plan, and nothing in this Agreement, express or implied, is intended to, or does, constitute the establishment of, or an amendment to, any benefit plan of Parent or the Surviving Corporation or any Benefit Plan.

7.6 Public Announcements. Parent shall consult with Company before issuing, and give the Company a reasonable opportunity to review and comment upon, any employee communication, press release or other public statements with respect to this Agreement, the Merger and the other transactions contemplated hereby and shall not issue any such communication, press release or make any public announcement without the prior consent of the Company, which consent shall not be unreasonably withheld, except as may be required by Applicable Law,

A-51

court process or by obligations pursuant to any listing agreement with any national securities exchange or national securities quotation system. For the avoidance of doubt, this Section shall not restrict Parent’s disclosure of information regarding the transactions contemplated hereby, including any information related to Parent’s determination to enter into this Agreement, to investors or prospective investors in Parent so long as such disclosures are made pursuant to a confidentiality agreement containing customary terms.

then, in any such event, the Company shall pay to Parent a fee of $11.0 million (the “Termination Fee”) less the amount of Parent Expenses previously paid to Parent (if any) pursuant to Section 9.6(b), it being understood that

A-55

in no event shall the Company be required to pay the Termination Fee on more than one occasion; provided, that the payment by the Company of the Termination Fee pursuant to this Section 9.6 shall not relieve the Company from any liability or damage resulting from a willful and material breach of any of its representations, warranties, covenants or agreements set forth in this Agreement or fraud. Payment of the Termination Fee shall be made by wire transfer of same day funds to the account designated by Parent (i) promptly after (and, in any event, within fifteen (15) Business Days of) the earliest to occur of any of the events requiring the payment of the Termination Fee pursuant to Section 9.6(a), (ii) promptly (and, in any event, within fifteen (15) Business Days of termination), in the case of termination by Parent pursuant to Section 9.4(a), or (iii) at the time required by Section 9.3(b), in the case of a termination by the Company pursuant to Section 9.3(b).

9.7 Acknowledgement. Each Party acknowledges that (a) the agreements contained in this Article IX are an integral part of the transactions contemplated by this Agreement, and (b) without the agreements contained in this Article IX, neither Parent nor the Company would have entered into this Agreement.

(c) Without in any way limiting the generality of Section 9.8(a), upon payment of the Reverse Termination Fee, no Parent Party shall have any further liability or obligation to the Company, any of its Affiliates or any of its or their direct or indirect stockholders relating to or arising out of this Agreement, the Limited Guaranty or the Financing Commitments, or the failure of the Merger or any other transaction contemplated hereby or thereby to be consummated, or in respect of any oral representation made or alleged to be have been made in connection herewith or therewith, whether in equity or at law, in contract, in tort or otherwise, and in such event, the Company shall not seek to, and shall cause its Affiliates and its and their direct and indirect stockholders not to seek to, recover any money damages (including consequential, indirect or punitive damages, or damages on account of a willful and material breach) or obtain any equitable relief from any Parent Party.

Each of the parties hereto (i) irrevocably submits itself to the personal jurisdiction of any court of proper subject matter jurisdiction in the State of California in the event any dispute arises out of this Agreement or the Merger, (ii) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court, and (iii) agrees that it will not bring any Action relating to this Agreement or the Merger in any court other than a court in the State of California, other than Actions in any court of competent jurisdiction to enforce any judgment, decree or award rendered by any such court. Each of the parties hereto further agrees that notice as provided herein shall constitute sufficient service of process and waives any argument that such service is insufficient. Each of the parties hereto hereby irrevocably and unconditionally waives, and agrees not to assert, by way of motion or as a defense, counterclaim or otherwise, in any Action related to or arising out of this Agreement or the Merger, that (i) the Action in any such court is brought in an inconvenient forum, (ii) the venue of such Action is improper or (iii) this Agreement or the subject matter hereof may not be enforced in or by such courts. Notwithstanding the foregoing or anything else to the contrary and without limiting the generality of Section 9.8(a), each of the parties hereto agrees that it will not bring or support any Action of any kind or description, whether in law or in equity, whether in contract or in tort or otherwise, against any Financing Source in any way relating to this Agreement or the transactions contemplated by this Agreement, including without limitation any dispute arising out of or relating to the Equity Commitment, Debt Financing Commitment, the Alternative Financing or the performance thereof, in any forum other than the United States District Court for the Southern District of New York or any New York State Court sitting in New York City, and that the provisions of Section 10.4 relating to the waiver of jury trial shall apply to any such Action.

Any assignment in violation of this provision shall be void.

10.6 Severability. If any provision of this Agreement, or the application thereof, shall for any reason and to any extent be invalid or unenforceable under any Applicable Law or jurisdiction, then (a) such invalidity, illegality or unenforceability shall not affect any other provision or portion of any provision in such jurisdiction, and the (b) remainder of this Agreement and the application of such provision to other Persons or circumstances shall be interpreted so as reasonably to effect the intent of the parties hereto.

10.8 Remedies; Specific Performance.

(a) Subject to Section 9.8, if any party should breach its covenants or agreements under this Agreement, the parties each acknowledge that it would be extremely impracticable to measure the resulting damages; accordingly, the parties agree that, in addition to any other available rights or remedies they may have under this Agreement, (i) Parent may sue in equity for specific performance and/or to obtain an injunction or injunctions to prevent or restrain breaches of this Agreement by the Company and to enforce specifically the terms and provisions of this Agreement to prevent breaches of, or to enforce compliance with, the covenants and obligations of such parties in any court of competent jurisdiction, and appropriate injunctive relief may be applied for and granted in connection therewith and (ii) the Company shall be entitled to specific performance only to the extent described in Section 10.8(b) and (c).

(b) Subject to Section 9.8, the Company shall be entitled to seek specific performance to cause Parent and Merger Sub to draw down the Equity Financing or to consummate the Merger only if:

(i) all conditions in Sections 8.1 and 8.2 (other than those conditions that by their nature are to be satisfied at the Closing) have been satisfied;

(ii) Parent and Merger Sub have failed to complete the Closing by the date the Closing is required to occur pursuant to Section 2.2;

(iii) the Debt Financing has been funded or will be funded at the Closing if the Equity Financing is funded at the Closing; and

(iv) the Company has irrevocably confirmed that if specific performance is granted and the Equity Financing and Debt Financing are funded, then the Closing will occur.

(c) Subject to Section 9.8, prior to any termination of this Agreement in accordance with Section 9.3, the Company shall be entitled to seek specific performance of the obligation of Parent pursuant to the terms of

A-58

this Agreement to draw down on the Debt Financing if the conditions to the availability of the Debt Financing have been satisfied or waived, but only in the event that each of the following conditions has been satisfied:

(i) all of the conditions set forth in Sections 8.1 and 8.2 have been and continue to be satisfied or waived (other than those conditions that by their nature are to be satisfied by actions taken at the Closing);

(ii) Parent fails to complete the Closing by the date the Closing is required to occur pursuant to Section 2.2;

(iii) all of the conditions to the consummation of the Debt Financing provided by the Debt Financing Commitments (or, if Alternative Financing is being used, pursuant to the commitments with respect thereto) have been satisfied (other than those conditions that by their nature are to be satisfied at the Closing); and

(iv) the Company has irrevocably confirmed in writing to Parent that the Company is ready, willing and able to consummate the Closing and if specific performance is granted and the Equity Financing and Debt Financing (or Alternative Financing) are funded, and Parent otherwise complies with its obligations hereunder, then the Closing will occur; provided, however, that in no event shall Parent be obligated to bring any Action against any of the other parties to the Debt Financing Commitment for breach of such party’s obligations under any Debt Financing Commitment or definitive financing agreement in order to enforce such party’s obligation.

10.9 Amendments and Waivers. Any term or provision of this Agreement may be amended, modified or supplemented, and the observance of any term of this Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively), only by a writing signed by the party to be bound thereby. The waiver by a party of any breach hereof or default in the performance hereof shall not be deemed to constitute a waiver of any other default or any succeeding breach or default. This Agreement may be amended by the parties hereto as provided in this Section 10.9 at any time before or after adoption of this Agreement by the Requisite Company Vote, but, after such adoption, no amendment shall be made which by Applicable Law requires the further approval of the Company Shareholders without obtaining such further approval. Notwithstanding anything to the contrary contained herein, Sections 9.5, 9.8, 10.1, 10.3, 10.4, 10.14(a) and this Section 10.9 (and any provision of this Agreement to the extent a modification, waiver or termination of such provision would modify the substance of Section 9.5, 9.8, 10.1, 10.3, 10.4, 10.14(a) and this Section 10.9) may not be modified, waived or terminated in a manner that impacts or is adverse in any respect to the Financing Sources without the prior written consent of the Financing Sources. At any time prior to the Effective Time, each of Company and Parent, may, to the extent authorized by their respective Board of Directors and to the extent permitted by Applicable Law, (a) extend the time for the performance of any of the obligations or other acts of the other, (b) waive any inaccuracies in the representations and warranties made to it contained herein or in any document delivered pursuant hereto, and (c) waive compliance with any of the agreements or conditions for its benefit contained herein; provided, however, that after the Requisite Company Vote has been obtained, no waiver may be made that pursuant to Applicable Law requires further approval or adoption by the stockholders of the Company without such further approval or adoption. No such waiver or extension shall be effective unless signed in writing by the party against whom such waiver or extension is asserted. The failure or delay of any party to enforce any of the provisions hereof shall not be construed to be a waiver of the right of such party thereafter to enforce such provisions, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such right or power, or any course of conduct, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the parties hereunder are cumulative and are not exclusive of any rights or remedies which they would otherwise have hereunder.

10.10 Expenses. Except as otherwise provided in Section 9.6, each party shall bear its respective legal, accountants, and financial advisory fees and other expenses incurred with respect to this Agreement, the Merger and the transactions contemplated hereby, whether or not the Merger is consummated. Notwithstanding the foregoing, (a) Parent and the Company shall share equally all filing fees required in connection with filings made under the HSR Act, and (b) in the event this Agreement is terminated for any reason other than by the Company

A-59

pursuant to Section 9.3(b), or Parent pursuant to 9.4(a) or 9.4(b), Parent shall reimburse the Company for half of the aggregate fees (other than attorneys’ fees) and expenses incurred in connection with filing the Company Proxy Statement and calling the Shareholders Meeting.

10.11 Attorneys’ Fees. Should suit be brought to enforce or interpret any part of this Agreement, the prevailing party shall be entitled to recover, as an element of the costs of suit and not as damages, reasonable attorneys’ fees to be fixed by the court (including costs, expenses and fees on any appeal). The prevailing party shall be entitled to recover its costs of suit, regardless of whether such suit proceeds to final judgment.

10.12 Notices. All notices and other communications required or permitted under this Agreement shall be in writing and shall be either hand delivered in person, sent by facsimile or email, sent by certified or registered first-class mail, postage pre-paid, or sent by nationally recognized express courier service.

ANNEX B

[LETTERHEAD OF HOULIHAN LOKEY CAPITAL, INC.]

August 15, 2013

The Special Committee of the Board of Directors

National Technical Systems, Inc.

24007 Ventura Boulevard, Suite 200

Calabasas, California 91302

Dear Special Committee:

We understand that National Technical Systems, Inc. (the “Company”), Nest Parent, Inc. (“Acquiror”), a newly-formed entity in which certain investment funds affiliated with Aurora Capital Group (“Aurora Capital”) will be controlling stockholders, and Nest Merger Sub, Inc. (“Merger Sub”), a wholly owned subsidiary of Acquiror, propose to enter into the Agreement (as defined below) pursuant to which, among other things, Merger Sub will be merged with and into the Company (the “Transaction”) and, in connection with the Transaction, (a) each outstanding share of common stock, no par value (“Company Common Stock”), of the Company will be converted into the right to receive $23.00 in cash (the “Consideration”), and (b) the Company will become a wholly owned subsidiary of Acquiror.

The Special Committee (the “Committee”) of the Board of Directors (the “Board”) of the Company has requested that Houlihan Lokey Capital, Inc. (“Houlihan Lokey”) provide an opinion (the “Opinion”) to the Committee as to whether, as of the date hereof, the Consideration to be received by holders of Company Common Stock in the Transaction pursuant to the Agreement is fair to such holders from a financial point of view.

In connection with this Opinion, we have made such reviews, analyses and inquiries as we have deemed necessary and appropriate under the circumstances. Among other things, we have:

1. reviewed an execution version of the Agreement and Plan of Merger, dated as of August 15, 2013, to be entered into by (a) the Company, a California corporation, (b) Acquiror, a Delaware corporation, and (c) Merger Sub, a California corporation (the “Agreement”);

2. reviewed certain publicly available business and financial information relating to the Company that we deemed to be relevant;

3. reviewed certain information relating to the historical, current and future operations, financial condition and prospects of the Company made available to us by the Company, including financial projections (and adjustments thereto) prepared by the management of the Company relating to the Company for the fiscal years ending 2014 through 2018;

4. spoken with certain members of the management of the Company and certain representatives and advisors of the Company regarding the business, operations, financial condition and prospects of the Company, the Transaction and related matters;

5. compared the financial and operating performance of the Company with that of other public companies that we deemed to be relevant;

6. considered publicly available financial terms of certain transactions that we deemed to be relevant;

7. reviewed the current and historical market prices and trading volume for Company Common Stock, and the current and historical market prices of the publicly traded securities of certain other companies that we deemed to be relevant;

B-1

The Special Committee of the Board of Directors

National Technical Systems, Inc.

August 15, 2013

8. considered the third-party solicitation process conducted by the Committee, with our assistance, with respect to a possible sale of the Company, including the Committee’s authorization of negotiations with Aurora Capital leading to the Transaction while such process was otherwise at a less advanced stage with other potential buyers; and

9. conducted such other financial studies, analyses and inquiries and considered such other information and factors as we deemed appropriate.

We have relied upon and assumed, without independent verification, the accuracy and completeness of all data, material and other information furnished, or otherwise made available, to us, discussed with or reviewed by us, or publicly available, and do not assume any responsibility with respect to such data, material and other information. In addition, management of the Company has advised us, and we have assumed, that the financial projections (and adjustments thereto) reviewed by us have been reasonably prepared in good faith on bases reflecting the best currently available estimates and judgments of such management as to the future financial results and condition of the Company, and we express no opinion with respect to such projections or the assumptions on which they are based. We have relied upon and assumed, without independent verification, that there has been no change in the business, assets, liabilities, financial condition, results of operations, cash flows or prospects of the Company since the respective dates of the most recent financial statements and other information, financial or otherwise, provided to us that would be material to our analyses or this Opinion, and that there is no information or any facts that would make any of the information reviewed by us incomplete or misleading. In addition, we have relied upon, without independent verification, the assessments of the management of the Company as to defense spending and other industry trends and prospects and the potential impact thereof on the Company, and have assumed, at the direction of the Company, that there will be no developments with respect to any such matters that would affect our analyses or this Opinion.

We have relied upon and assumed, without independent verification, that (a) the representations and warranties of all parties to the Agreement and all other related documents and instruments that are referred to therein are true and correct, (b) each party to the Agreement and such other related documents and instruments will fully and timely perform all of the covenants and agreements required to be performed by such party, (c) all conditions to the consummation of the Transaction will be satisfied without waiver thereof, and (d) the Transaction will be consummated in a timely manner in accordance with the terms described in the Agreement and such other related documents and instruments, without any amendments or modifications thereto. We have relied upon and assumed, without independent verification, that (i) the Transaction will be consummated in a manner that complies in all respects with all applicable federal and state statutes, rules and regulations, and (ii) all governmental, regulatory, and other consents and approvals necessary for the consummation of the Transaction will be obtained and that no delay, limitations, restrictions or conditions will be imposed or amendments, modifications or waivers made that would have an effect on the Transaction or the Company that would be material to our analyses or this Opinion. In addition, we have relied upon and assumed, without independent verification, that the Agreement, when executed, will not differ in any respect from the execution version of the Agreement identified above.

Furthermore, in connection with this Opinion, we have not been requested to make, and have not made, any physical inspection or independent appraisal or evaluation of any of the assets, properties or liabilities (fixed, contingent, derivative, off-balance-sheet or otherwise) of the Company or any other party, nor were we provided with any such appraisal or evaluation. With respect to the Company’s excess property located in Santa Clarita, California, we have relied upon, without independent verification, the proposed purchase price offered in a non-binding letter of intent received by the Company from a third party for purposes of our analyses and this Opinion. We did not estimate, and express no opinion regarding, the liquidation value of any entity or business. We have

B-2

The Special Committee of the Board of Directors

National Technical Systems, Inc.

August 15, 2013

undertaken no independent analysis of any potential or actual litigation, regulatory action, possible unasserted claims or other contingent liabilities, to which the Company is or may be a party or is or may be subject, or of any governmental investigation of any possible unasserted claims or other contingent liabilities to which the Company is or may be a party or is or may be subject.

This Opinion is necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. We have not undertaken, and are under no obligation, to update, revise, reaffirm or withdraw this Opinion, or otherwise comment on or consider events occurring or coming to our attention after the date hereof. We are not expressing any opinion as to the price or range of prices at which Company Common Stock may be purchased or sold, or otherwise be transferable, at any time.

This Opinion is furnished for the use of the Committee (in its capacity as such) and, at the request of the Committee, the Board (in its capacity as such) in connection with their evaluation of the Transaction and may not be used for any other purpose without our prior written consent. This Opinion should not be construed as creating any fiduciary duty on Houlihan Lokey’s part to any party. This Opinion is not intended to be, and does not constitute, a recommendation to the Committee, the Board, the Company, any security holder or any other party as to how to act or vote with respect to any matter relating to the Transaction or otherwise.

In the ordinary course of business, certain of our employees and affiliates, as well as investment funds in which they may have financial interests or with which they may co-invest, may acquire, hold or sell, long or short positions, or trade, in debt, equity, and other securities and financial instruments (including loans and other obligations) of, or investments in, the Company, one or more affiliates of Aurora Capital or any other party that may be involved in the Transaction and their respective affiliates or any currency or commodity that may be involved in the Transaction.

An affiliate of Houlihan Lokey has in the past provided certain financial advisory services to an affiliate of Aurora Capital, for which such affiliate of Houlihan Lokey received and is entitled to receive compensation. Houlihan Lokey and certain of its affiliates may provide investment banking, financial advisory and other financial services to the Company, Acquiror, Aurora Capital or one or more security holders, affiliates and/or portfolio companies of investment funds affiliated or associated with Aurora Capital (collectively, “Aurora”), other participants in the Transaction or certain of their respective affiliates or security holders in the future, for which Houlihan Lokey and its affiliates may receive compensation. In addition, Houlihan Lokey and certain of its affiliates and certain of our and their respective employees may have committed to invest in private equity or other investment funds managed or advised by Aurora Capital, other participants in the Transaction or certain of their respective affiliates, and in portfolio companies of such funds, and may have co-invested with Aurora, other participants in the Transaction or certain of their respective affiliates or security holders, and may do so in the future. Furthermore, in connection with bankruptcies, restructurings, and similar matters, Houlihan Lokey and certain of its affiliates may have in the past acted, may currently be acting and may in the future act as financial advisor to debtors, creditors, equity holders, trustees, agents and other interested parties (including, without limitation, formal and informal committees or groups of creditors) that may have included or represented and may include or represent, directly or indirectly, or may be or have been adverse to, the Company, Acquiror, Aurora, other participants in the Transaction or certain of their respective affiliates or security holders, for which advice and services Houlihan Lokey and its affiliates have received and may receive compensation.

Houlihan Lokey has also acted as financial advisor to the Committee in connection with, and has participated in certain of the negotiations leading to, the Transaction and will receive a fee for such services, the principal portion of which is contingent upon the consummation of the Transaction. In addition, we will receive a

B-3

The Special Committee of the Board of Directors

National Technical Systems, Inc.

August 15, 2013

fee for rendering this Opinion, which is not contingent upon the successful completion of the Transaction or the conclusion contained in this Opinion. The Company has agreed to reimburse certain of our expenses and to indemnify us and certain related parties for certain potential liabilities arising out of our engagement.

We have not been requested to opine as to, and this Opinion does not express an opinion as to or otherwise address, among other things: (i) the underlying business decision of the Committee, the Board, the Company, its security holders or any other party to proceed with or effect the Transaction, (ii) the terms of any arrangements, understandings, agreements or documents related to, or the form, structure or any other portion or aspect of, the Transaction or otherwise (other than the Consideration to the extent expressly specified herein), (iii) the fairness of any portion or aspect of the Transaction to the holders of any class of securities, creditors or other constituencies of the Company, or to any other party, except if and only to the extent expressly set forth in the last sentence of this Opinion, (iv) the relative merits of the Transaction as compared to any alternative business strategies or transactions that might be available for the Company or any other party, (v) the fairness of any portion or aspect of the Transaction to any one class or group of the Company’s or any other party’s security holders or other constituents vis-à-vis any other class or group of the Company’s or such other party’s security holders or other constituents (including, without limitation, the allocation of any consideration amongst or within such classes or groups of security holders or other constituents), (vi) whether or not the Company, its security holders, Acquiror or any other party is receiving or paying reasonably equivalent value in the Transaction, (vii) the solvency, creditworthiness or fair value of the Company, Acquiror or any other participant in the Transaction, or any of their respective assets, under any applicable laws relating to bankruptcy, insolvency, fraudulent conveyance or similar matters, or (viii) the fairness, financial or otherwise, of the amount, nature or any other aspect of any compensation to or consideration payable to or received by any officers, directors or employees of any party to the Transaction, any class of such persons or any other party, relative to the Consideration or otherwise. Furthermore, no opinion, counsel or interpretation is intended in matters that require legal, regulatory, accounting, insurance, tax or other similar professional advice. It is assumed that such opinions, counsel or interpretations have been or will be obtained from appropriate professional sources. Furthermore, we have relied, with the consent of the Committee, on the assessments by the Committee, the Board, the Company and their respective advisors as to all legal, regulatory, accounting, insurance and tax matters with respect to the Company, the Transaction or otherwise. The issuance of this Opinion was approved by a committee authorized to approve opinions of this nature.

Based upon and subject to the foregoing, and in reliance thereon, it is our opinion that, as of the date hereof, the Consideration to be received by holders of Company Common Stock in the Transaction pursuant to the Agreement is fair to such holders from a financial point of view.

Very truly yours,

/s/ Houlihan Lokey Capital, Inc.

§ 1300.

(a) If the approval of the outstanding shares (Section 152) of a corporation is required for a reorganization under subdivisions (a) and (b) or subdivision (e) or (f) of Section 1201, each shareholder of the corporation entitled to vote on the transaction and each shareholder of a subsidiary corporation in a short-form merger may, by complying with this chapter, require the corporation in which the shareholder holds shares to purchase for cash at their fair market value the shares owned by the shareholder which are dissenting shares as defined in subdivision (b). The fair market value shall be determined as of the day of, and immediately prior to, the first announcement of the terms of the proposed reorganization or short-form merger, excluding any appreciation or depreciation in consequence of the proposed reorganization or short-form merger, as adjusted for any stock split, reverse stock split, or share dividend that becomes effective thereafter.

(b) As used in this chapter, “dissenting shares” means shares to which all of the following apply:

(1) That were not, immediately prior to the reorganization or short-form merger, listed on any national securities exchange certified by the Commissioner of Corporations under subdivision (o) of Section 25100, and the notice of meeting of shareholders to act upon the reorganization summarizes this section and Sections 1301, 1302, 1303 and 1304; provided, however, that this provision does not apply to any shares with respect to which there exists any restriction on transfer imposed by the corporation or by any law or regulation; and provided, further, that this provision does not apply to any shares where the holder of those shares is required, by the terms of the reorganization or short-form merger, to accept for the shares anything except: (A) shares of any other corporation, which shares, at the time the reorganization or short-form merger is effective, are listed on any national securities exchange certified by the Commissioner of Corporations under subdivision (o) of Section 25100; (B) cash in lieu of fractional shares described in the foregoing subparagraph (A); or (C) any combination of the shares and cash in lieu of fractional shares described in the foregoing subparagraphs (A) and (B).

(2) That were outstanding on the date for the determination of shareholders entitled to vote on the reorganization and (A) were not voted in favor of the reorganization or, (B) if described in paragraph (1), were voted against the reorganization, or were held of record on the effective date of a short-form merger; provided, however, that subparagraph (A) rather than subparagraph (B) of this paragraph applies in any case where the approval required by Section 1201 is sought by written consent rather than at a meeting.

(3) That the dissenting shareholder has demanded that the corporation purchase at their fair market value, in accordance with Section 1301.

(4) That the dissenting shareholder has submitted for endorsement, in accordance with Section 1302.

(c) As used in this chapter, “dissenting shareholder” means the recordholder of dissenting shares and includes a transferee of record.

§ 1301.

(a) If, in the case of a reorganization, any shareholders of a corporation have a right under Section 1300, subject to compliance with paragraphs (3) and (4) of subdivision (b) thereof, to require the corporation to purchase their shares for cash, that corporation shall mail to each of those shareholders a notice of the approval of the reorganization by its outstanding shares (Section 152) within 10 days after the date of that approval, accompanied by a copy of Sections 1300, 1302, 1303, and 1304 and this section, a statement of the price determined by the corporation to represent the fair market value of the dissenting shares, and a brief description

C-1

of the procedure to be followed if the shareholder desires to exercise the shareholder’s right under those sections. The statement of price constitutes an offer by the corporation to purchase at the price stated any dissenting shares as defined in subdivision (b) of Section 1300, unless they lose their status as dissenting shares under Section 1309.

(b) Any shareholder who has a right to require the corporation to purchase the shareholder’s shares for cash under Section 1300, subject to compliance with paragraphs (3) and (4) of subdivision (b) thereof, and who desires the corporation to purchase shares shall make written demand upon the corporation for the purchase of those shares and payment to the shareholder in cash of their fair market value. The demand is not effective for any purpose unless it is received by the corporation or any transfer agent thereof (1) in the case of shares described in subdivision (b) of Section 1300, not later than the date of the shareholders’ meeting to vote upon the reorganization, or (2) in any other case, within 30 days after the date on which the notice of the approval by the outstanding shares pursuant to subdivision (a) or the notice pursuant to subdivision (h) of Section 1110 was mailed to the shareholder.

(c) The demand shall state the number and class of the shares held of record by the shareholder which the shareholder demands that the corporation purchase and shall contain a statement of what the shareholder claims to be the fair market value of those shares as determined pursuant to subdivision (a) of Section 1300. The statement of fair market value constitutes an offer by the shareholder to sell the shares at that price.

§ 1302.

Within 30 days after the date on which notice of the approval by the outstanding shares or the notice pursuant to subdivision (h) of Section 1110 was mailed to the shareholder, the shareholder shall submit to the corporation at its principal office or at the office of any transfer agent thereof, (a) if the shares are certificated securities, the shareholder’s certificates representing any shares which the shareholder demands that the corporation purchase, to be stamped or endorsed with a statement that the shares are dissenting shares or to be exchanged for certificates of appropriate denomination so stamped or endorsed or (b) if the shares are uncertificated securities, written notice of the number of shares which the shareholder demands that the corporation purchase. Upon subsequent transfers of the dissenting shares on the books of the corporation, the new certificates, initial transaction statement, and other written statements issued therefor shall bear a like statement, together with the name of the original dissenting holder of the shares.

§ 1303.

(a) If the corporation and the shareholder agree that the shares are dissenting shares and agree upon the price of the shares, the dissenting shareholder is entitled to the agreed price with interest thereon at the legal rate on judgments from the date of the agreement. Any agreements fixing the fair market value of any dissenting shares as between the corporation and the holders thereof shall be filed with the secretary of the corporation.

(b) Subject to the provisions of Section 1306, payment of the fair market value of dissenting shares shall be made within 30 days after the amount thereof has been agreed or within 30 days after any statutory or contractual conditions to the reorganization are satisfied, whichever is later, and in the case of certificated securities, subject to surrender of the certificates therefor, unless provided otherwise by agreement.

§ 1304.

(a) If the corporation denies that the shares are dissenting shares, or the corporation and the shareholder fail to agree upon the fair market value of the shares, then the shareholder demanding purchase of such shares as dissenting shares or any interested corporation, within six months after the date on which notice of the approval by the outstanding shares (Section 152) or notice pursuant to subdivision (h) of Section 1110 was mailed to the shareholder, but not thereafter, may file a complaint in the superior court of the proper county praying the court to determine whether the shares are dissenting shares or the fair market value of the dissenting shares or both or may intervene in any action pending on such a complaint.

C-2

(b) Two or more dissenting shareholders may join as plaintiffs or be joined as defendants in any such action and two or more such actions may be consolidated.

(c) On the trial of the action, the court shall determine the issues. If the status of the shares as dissenting shares is in issue, the court shall first determine that issue. If the fair market value of the dissenting shares is in issue, the court shall determine, or shall appoint one or more impartial appraisers to determine, the fair market value of the shares.

§ 1305.

(a) If the court appoints an appraiser or appraisers, they shall proceed forthwith to determine the fair market value per share. Within the time fixed by the court, the appraisers, or a majority of them, shall make and file a report in the office of the clerk of the court. Thereupon, on the motion of any party, the report shall be submitted to the court and considered on such evidence as the court considers relevant. If the court finds the report reasonable, the court may confirm it.

(b) If a majority of the appraisers appointed fail to make and file a report within 10 days from the date of their appointment or within such further time as may be allowed by the court or the report is not confirmed by the court, the court shall determine the fair market value of the dissenting shares.

(c) Subject to the provisions of Section 1306, judgment shall be rendered against the corporation for payment of an amount equal to the fair market value of each dissenting share multiplied by the number of dissenting shares which any dissenting shareholder who is a party, or who has intervened, is entitled to require the corporation to purchase, with interest thereon at the legal rate from the date on which judgment was entered.

(d) Any such judgment shall be payable forthwith with respect to uncertificated securities and, with respect to certificated securities, only upon the endorsement and delivery to the corporation of the certificates for the shares described in the judgment. Any party may appeal from the judgment.

(e) The costs of the action, including reasonable compensation to the appraisers to be fixed by the court, shall be assessed or apportioned as the court considers equitable, but, if the appraisal exceeds the price offered by the corporation, the corporation shall pay the costs (including in the discretion of the court attorneys’ fees, fees of expert witnesses and interest at the legal rate on judgments from the date of compliance with Sections 1300, 1301 and 1302 if the value awarded by the court for the shares is more than 125 percent of the price offered by the corporation under subdivision (a) of Section 1301).

§ 1306.

To the extent that the provisions of Chapter 5 prevent the payment to any holders of dissenting shares of their fair market value, they shall become creditors of the corporation for the amount thereof together with interest at the legal rate on judgments until the date of payment, but subordinate to all other creditors in any liquidation proceeding, such debt to be payable when permissible under the provisions of Chapter 5.

§ 1307.

Cash dividends declared and paid by the corporation upon the dissenting shares after the date of approval of the reorganization by the outstanding shares (Section 152) and prior to payment for the shares by the corporation shall be credited against the total amount to be paid by the corporation therefor.

§ 1308.

Except as expressly limited in this chapter, holders of dissenting shares continue to have all the rights and privileges incident to their shares, until the fair market value of their shares is agreed upon or determined. A dissenting shareholder may not withdraw a demand for payment unless the corporation consents thereto.

C-3

§ 1309.

Dissenting shares lose their status as dissenting shares and the holders thereof cease to be dissenting shareholders and cease to be entitled to require the corporation to purchase their shares upon the happening of any of the following:

(a) The corporation abandons the reorganization. Upon abandonment of the reorganization, the corporation shall pay on demand to any dissenting shareholder who has initiated proceedings in good faith under this chapter all necessary expenses incurred in such proceedings and reasonable attorneys’ fees.

(b) The shares are transferred prior to their submission for endorsement in accordance with Section 1302 or are surrendered for conversion into shares of another class in accordance with the articles.

(c) The dissenting shareholder and the corporation do not agree upon the status of the shares as dissenting shares or upon the purchase price of the shares, and neither files a complaint or intervenes in a pending action as provided in Section 1304, within six months after the date on which notice of the approval by the outstanding shares or notice pursuant to subdivision (h) of Section 1110 was mailed to the shareholder.

(d) The dissenting shareholder, with the consent of the corporation, withdraws the shareholder’s demand for purchase of the dissenting shares.

§ 1310.

If litigation is instituted to test the sufficiency or regularity of the votes of the shareholders in authorizing a reorganization, any proceedings under Sections 1304 and 1305 shall be suspended until final determination of such litigation.

§ 1311.

This chapter, except Section 1312, does not apply to classes of shares whose terms and provisions specifically set forth the amount to be paid in respect to such shares in the event of a reorganization or merger.

§ 1312.

(a) No shareholder of a corporation who has a right under this chapter to demand payment of cash for the shares held by the shareholder shall have any right at law or in equity to attack the validity of the reorganization or short-form merger, or to have the reorganization or short-form merger set aside or rescinded, except in an action to test whether the number of shares required to authorize or approve the reorganization have been legally voted in favor thereof; but any holder of shares of a class whose terms and provisions specifically set forth the amount to be paid in respect to them in the event of a reorganization or short-form merger is entitled to payment in accordance with those terms and provisions or, if the principal terms of the reorganization are approved pursuant to subdivision (b) of Section 1202, is entitled to payment in accordance with the terms and provisions of the approved reorganization.

(b) If one of the parties to a reorganization or short-form merger is directly or indirectly controlled by, or under common control with, another party to the reorganization or short-form merger, subdivision (a) shall not apply to any shareholder of such party who has not demanded payment of cash for such shareholder’s shares pursuant to this chapter; but if the shareholder institutes any action to attack the validity of the reorganization or short-form merger or to have the reorganization or short-form merger set aside or rescinded, the shareholder shall not thereafter have any right to demand payment of cash for the shareholder’s shares pursuant to this chapter. The court in any action attacking the validity of the reorganization or short-form merger or to have the reorganization or short-form merger set aside or rescinded shall not restrain or enjoin the consummation of the transaction except upon 10 days’ prior notice to the corporation and upon a determination by the court that clearly no other remedy will adequately protect the complaining shareholder or the class of shareholders of which such shareholder is a member.

C-4

(c) If one of the parties to a reorganization or short-form merger is directly or indirectly controlled by, or under common control with, another party to the reorganization or short-form merger, in any action to attack the validity of the reorganization or short-form merger or to have the reorganization or short-form merger set aside or rescinded, (1) a party to a reorganization or short-form merger which controls another party to the reorganization or short-form merger shall have the burden of proving that the transaction is just and reasonable as to the shareholders of the controlled party, and (2) a person who controls two or more parties to a reorganization shall have the burden of proving that the transaction is just and reasonable as to the shareholders of any party so controlled.

§ 1313.

A conversion pursuant to Chapter 11.5 (commencing with Section 1150) shall be deemed to constitute a reorganization for purposes of applying the provisions of this chapter, in accordance with and to the extent provided in Section 1159.
