PROXY STATEMENT
for
ANNUAL MEETING OF STOCKHOLDERS
to be Held May 17, 2012

SOLICITATION AND REVOCABILITY OF PROXIES

The enclosed proxy (the “Proxy”) is being solicited on behalf of the Board of Directors (the “Board”) of Intrusion Inc. (the “Company”) for use at the Annual Meeting of Stockholders (the “Meeting”) to be held at the Doubletree Hotel- Richardson, 1981 North Central Expressway, Richardson, Texas, at 10:00 A.M., Local Time, on Thursday, May 17, 2012, or at such other time and place to which the Meeting may be adjourned.  Proxies, together with copies of this Proxy Statement, are first being mailed to stockholders of record entitled to vote at the Meeting on or about April 13, 2012.

Execution and return of the enclosed Proxy will not affect a stockholder’s right to attend the Meeting and to vote in person.  Any stockholder executing a Proxy retains the right to revoke such proxy at any time prior to exercise at the Meeting.  A Proxy may be revoked by delivery of written notice of revocation to the Secretary of the Company, by execution and delivery of a later Proxy or by voting the shares in person at the Meeting.  If you attend the Meeting and vote in person by ballot, your proxy will be revoked automatically and only your vote at the Meeting will be counted.  A Proxy, when executed and not revoked, will be voted in accordance with the instructions thereon.  In the absence of specific instructions, Proxies will be voted by those named in the Proxy “FOR” the election as directors of those nominees named in the Proxy Statement, “FOR” the approval of each of the other proposals described in this Proxy Statement, and in accordance with their best judgment on all other matters that may properly come before the Meeting.

The enclosed form of Proxy provides a method for stockholders to withhold authority to vote for any one or more of the nominees for director while granting authority to vote for the remaining nominees.  The names of all nominees are listed on the Proxy.  If you wish to grant authority to vote for all nominees, check the box marked “FOR.” If you wish to withhold authority to vote for all nominees, check the box marked “WITHHOLD.” If you wish your shares to be voted for some nominees and not for one or more of the others, check the box marked “FOR” and indicate the name(s) of the nominee(s) for whom you are withholding the authority to vote by writing the name(s) of such nominee(s) on the Proxy in the space provided.

RECORD DATE AND VOTING SECURITIES

Only stockholders of record at the close of business on March 30, 2012 are entitled to notice of, and to vote at, the Meeting.  The stock transfer books of the Company will remain open between the record date and the date of the Meeting.  A list of stockholders entitled to vote at the Meeting will be available for inspection at the executive offices of the Company.  On the March 30, 2012 record date, the Company had 11,972,017 outstanding shares of Common Stock, $0.01 par value (the “Common Stock”); 220,000 outstanding shares of 5% Convertible Preferred Stock, par value $0.01 per share (the “5% Preferred Stock”); 460,000 shares of Series 2 5% Convertible Preferred Stock, par value $0.01 per share (the “Series 2 5% Preferred Stock”) and 354,056 shares of Series 3 5% Convertible Preferred Stock, par value $0.01 per share (the “Series 3 5% Preferred Stock”).  The holders of Series 2 and Series 3 5% Preferred Stock do not have voting rights, other than as required by the Delaware General Corporation Law. Therefore, the holders of the Series 2 and Series 3 5% Preferred Stock are not entitled to vote with respect to the proposals set forth in this Proxy Statement.

QUORUM AND VOTING

The presence at the Meeting, in person or by Proxy, of the holders of a majority of the shares of Common Stock outstanding or issuable upon conversion of the 5% Preferred Stock is necessary to constitute a quorum.  Holders of Common Stock are entitled to one vote for each share of Common Stock held on each matter to be voted on at the

1

Meeting including the election of directors.  Holders of 5% Preferred Stock are entitled to vote on an as-converted to Common Stock basis, with any fractional votes being rounded to the nearest whole vote.  As of the record date, each share of 5% Preferred Stock was convertible into 1.59 shares of Common Stock.  As a result, each holder is entitled to 1.59 votes for each share of 5% Preferred Stock held on each matter to be voted on at the Meeting, including the election of directors, representing an aggregate of approximately 349,800 votes attributable to holders of the 5% Preferred Stock or 2.8% of total votes entitled to be cast at the Meeting.

All votes will be tabulated by the inspector of election appointed for the Meeting, who will separately tabulate affirmative and negative votes, abstentions and broker non-votes.  Abstentions and broker non-votes are counted as present for purposes of determining the presence or absence of a quorum for the transaction of business.  Abstentions will be counted towards the tabulations of votes cast on matters presented at the Meeting and will have the same effect as negative votes (other than the election of directors) whereas broker non-votes will not be counted for purposes of determining whether a matter has been approved.

Assuming the presence of a quorum, the following paragraphs describe the vote required by the stockholders of record to approve each of the proposals set forth in this Proxy Statement.

·                                          Proposal One.  The five nominees receiving the greatest number of votes of the shares of Common Stock outstanding or issuable upon conversion of the 5% Preferred Stock present in person or represented by Proxy at the Meeting and entitled to vote shall be deemed elected even if they receive the affirmative vote of less than a majority of the shares of Common Stock outstanding or issuable upon conversion of the 5% Preferred Stock entitled to be voted at the Meeting.  Cumulative voting is prohibited in the election of directors, and Proxies cannot be voted for more than five nominees.

·                                          Proposal Two.  The affirmative vote of the holders of a majority of the shares of Common Stock outstanding or issuable upon conversion of the 5% Preferred Stock entitled to vote at the Meeting and present in person or by Proxy, is required for the approval to the amendment of the 2005 Incentive Stock Plan.

·                                          Proposal Three.  The affirmative vote of the holders of a majority of the shares of Common Stock outstanding or issuable upon conversion of the 5% Preferred Stock entitled to vote at the Meeting and present in person or by Proxy, is required for the ratification of the appointment of Whitley Penn LLP as independent auditors.

The Board unanimously recommends a vote “FOR” each of the proposals set forth in this Proxy Statement.

PROPOSAL ONE

Paxton, Vice President, Chief Financial Officer, Secretary and Treasurer, is the son of G. Ward Paxton, Chairman, President and Chief Executive Officer.

Stockholder Approval

The affirmative vote of a plurality of the shares of Common Stock outstanding or issuable upon conversion of outstanding 5% Preferred Stock present in person or by proxy at the Meeting is required for the election of each of the nominees for director.

The Board recommends a vote “FOR” the election of such nominees.

CORPORATE GOVERNANCE

The business affairs of the Company are managed under the direction of the Board.  The Board meets on a regularly scheduled basis during the fiscal year of the Company to review significant developments affecting the Company and to act on matters requiring Board approval.  It also holds special meetings as required from time to time when important matters arise requiring Board action between scheduled meetings.  The Board of Directors or its authorized committees met 16 times during the 2011 fiscal year.  During fiscal year 2011, each director participated in at least 75% or more of the aggregate of (1) the total number of meetings of the Board of Directors (held during the period for which he was a director) and (2) the total number of meetings of all committees of the Board on which he served (during the period that he served).

Board Leadership Structure

The current leadership structure of the Company provides for the combination of the roles of the Chairman of the Board and the Chief Executive Officer.  The Board believes that the Chief Executive Officer is best situated to serve as the Chairman of the Board because he is the director most familiar with the Company’s business and industry, and most capable of effectively identifying strategic priorities and leading the discussion and execution of strategy.  Independent directors and management have different perspectives and roles in strategy development.  The Company’s independent directors bring experience, oversight and expertise from outside the Company and industry, while the Chief Executive Officer brings Company-specific experience and expertise.  One of the key responsibilities of the Board is to develop the Company’s strategic direction and hold management accountable for the execution of strategy once it is developed.  The Company believes that the combined role of Chairman of the Board and Chief Executive Officer is in the best interest of the Company’s stockholders because it promotes strategy development and execution, and facilitates information flow between management and the Board, which are essential to effective governance of the Company.

4

The Company also believes that the combined role of the Chairman of the Board and the Chief Executive Officer is appropriate in light of the independent oversight of the Board.  Although the Board has not designated a lead independent director, the Company has a long history of strong independent directors, with 3 out of the 5 current members of the Board being independent.  In addition, the Audit and Compensation Committees of the Board are comprised solely of independent directors.  The Board regularly reviews the Company’s leadership structure and reserves the right to alter the structure as it deems appropriate.

Board Role in Risk Oversight and Management

The Board has an active role in the oversight and management of the Company’s risks and carries out its role directly and through Board committees.  The Board’s direct role in the Company’s risk management process includes regular or periodic receipt and discussion of reports from management and the Company’s outside counsel and advisers on areas of material risk to the Company, including operational, strategic, financial, legal and regulatory risks.

The Board has also historically delegated the oversight and management of certain risks to the Audit and Compensation Committees of the Board.  The Audit Committee is responsible for the oversight of Company risks relating to accounting matters, financial reporting and related party transactions.  To satisfy these oversight responsibilities, the Audit Committee regularly meets with and receives and discusses reports from the Chief Financial Officer, the Company’s independent registered public accountant, and the Company’s outside counsel.  The Compensation Committee is responsible for the oversight of risks relating to the Company’s compensation and benefit programs.  To satisfy these oversight responsibilities, the Compensation Committee regularly meets with and receives and discusses reports from the Chief Executive Officer and the Chief Financial Officer to understand the financial, human resources and stockholder implications of compensation and benefit decisions.

The Board has also addressed risk through the adoption of corporate policies.  The Board has adopted a Code of Business Conduct and Ethics and a Code of Ethics for Senior Financial Employees that are designed to ensure that directors, officers and employees of the Company are aware of their legal and ethical responsibilities and conduct the Company’s business in a consistently legal and ethic manner.

Committees

The Board has established Audit and Compensation Committees to devote attention to specific subjects and to assist it in the discharge of its responsibilities.  The functions of the Audit Committee and the Compensation Committee are described below.

Audit Committee.  The Audit Committee is composed of:  Donald M. Johnston (Chairman), James F. Gero, and J. Fred Bucy, Jr.  Each member of the Audit Committee is independent (as defined in Nasdaq Marketplace Rule 5605(a)(2)).  The Audit Committee has at least one financial expert (as defined by 407 (d)(5)(ii) of Regulation S-K).  Mr. Bucy is currently the Audit Committee financial expert.  The functions performed by the Audit Committee, its membership and the number of meetings held during the fiscal year, are set forth in the “Report of the Audit Committee,” included in this Proxy Statement.  The Audit Committee is governed by a written charter, which was approved by the Audit Committee on March 18, 2004, and is included under the “investor relations” section on the Company’s website, www.intrusion.com.  The Audit Committee held six meetings during fiscal year 2011.

Compensation Committee.  The Compensation Committee is composed of Mr. Gero (Chairman), Mr. Bucy and Mr. Johnston, each of whom is an independent director, as defined by Nasdaq Rule 4200.  The Compensation Committee met five times during the 2011 fiscal year.  The Compensation Committee is empowered to advise management and make recommendations to the Board with respect to the compensation and other employment benefits of executive officers, key employees and directors of the Company.  The Compensation Committee also administers the Company’s stock incentive plan for officers, key employees and directors, and the Company’s incentive bonus programs for executive officers and employees.  The Compensation Committee is authorized, among other powers, to determine from time to time the individuals to whom options shall be granted, the number of shares to be covered by each option and the time or times at which options shall be granted pursuant to the stock incentive plan.  The Compensation Committee currently operates without a written charter.

5

Notwithstanding anything to the contrary set forth in any of the Company’s previous or future filings under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that might incorporate this Proxy or future filings made by the Company under those statutes, the Compensation Committee Report, the Audit Committee Report, the Audit Committee Charter and references to the independence of Audit Committee members are not deemed filed with the Securities and Exchange Commission (the “SEC”).  They also shall not be deemed incorporated by reference into any of those prior filings or into any future filings made by the Company under those statutes, except the extent the Company specifically incorporates such information by reference in such filings.

Report of the Audit Committee

The Audit Committee oversees the Company’s financial reporting process on behalf of the Board.  Management has the primary responsibility for the financial statements and the reporting process, including the systems of internal controls.  In fulfilling its oversight responsibilities, the Audit Committee reviewed the audited financial statements in the Annual Report with management including a discussion of the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments, and the clarity of disclosures in the financial statements.

The Audit Committee reviewed with Whitley Penn LLP, the Independent Registered Public Accounting Firm to the Company, who are responsible for expressing an opinion on the conformity of those audited financial statements with generally accepted accounting principles, their judgments as to the quality, not just the acceptability, of the Company’s accounting principles, the matters required to be discussed by SAS 114 (The Auditor’s Communication with Those Charged with Governance), as amended, and such other matters as are required to be discussed with the Audit Committee under generally accepted auditing standards.  In addition, the Audit Committee has discussed with Whitley Penn LLP the auditors’ independence from management and the Company, including the matters in the written disclosures and the letter from Whitley Penn LLP required by applicable professional and regulatory standards including those of the Public Company Accounting Oversight Board, and considered the compatibility of non-audit services with the auditors’ independence.

The Audit Committee discussed with Whitley Penn LLP the overall scope and plans for their audit.  The Audit Committee meets with Whitley Penn LLP, with and without management present, to discuss the results of their examinations, their evaluations of the Company’s internal controls, and the overall quality of the Company’s financial reporting.  The Audit Committee held six meetings during fiscal year 2011.

In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board (and the Board has approved) that the audited financial statements be included in the Annual Report on Form 10-K for the year ended December 31, 2011 for filing with the SEC.  The Audit Committee and the Board have also recommended, subject to stockholder ratification, the selection of Whitley Penn LLP as the Company’s Independent Registered Public Accounting Firm.

REPORT OF COMPENSATION COMMITTEE

The Compensation Committee is responsible for administering the compensation programs of the executive officers. The Compensation Committee sets performance goals and objectives for the Chief Executive Officer and the other executive officers, evaluates their performance with respect to those goals and sets their compensation based upon the evaluation of their performance. In evaluating executive officer pay, the Compensation Committee may consider recommendations from the Chief Executive Officer with respect to goals and compensation of the other executive officers. The Compensation Committee also periodically reviews director compensation. All decisions with respect to executive and director compensation are approved by the Compensation Committee and recommended to the full Board for ratification.

The Compensation Committee is responsible for administering all of the Company’s equity-based plans. The Compensation Committee also periodically reviews compensation and equity-based plans and makes its recommendations to the board with respect to these areas.

On February 9, 2012, the Committee approved an amendment to the Company’s 2005 Stock Incentive Plan (the “Amended 2005 Plan”) as a replacement to the 2005 Stock Incentive Plan (the “2005 Plan”).  If approved by the stockholders under Proposal Two, the Amended 2005 Plan will become effective on May 17, 2012.  A full description of the Amended 2005 Plan can be found in the section “Proposal Two-Proposal to Approve Amendment to the 2005 Stock Incentive Plan.”

It is the opinion of the Compensation Committee that the executive compensation policies and plans, including, without limitation, the Amended 2005 Plan, provide the necessary total remuneration program to properly align the Company’s performance and the interests of the Company’s stockholders through the use of competitive and equitable executive compensation in a balanced and reasonable manner, for both the short and long-term.

7

Nomination of Directors

The Company does not have a formal nominating committee.  Instead, the independent members of the Board, Mr. Bucy, Mr. Gero and Mr. Johnston, act as a nominating committee considering nominees and appointees to the Board in accordance with Nasdaq Marketplace Rule 5605(e), and the Board believes that the independent directors can serve effectively in this capacity without the need for a formal committee.  In nominating and evaluating candidates to determine if they are qualified to become Board members, these Directors consider a number of attributes, including:

·                                          personal and professional character, integrity, ethics and values, without regard to race, religion, gender or national origin;

·                                          general business experience and leadership profile, including experience in corporate management, such as serving as an officer or former officer of a publicly held company, or experience as a board member of another publicly held company;

·                                          strategic planning abilities and experience;

·                                          aptitude in accounting and finance;

·                                          expertise in domestic and international markets;

·                                          experience in the network security or telecommunications industry;

·                                          understanding of relevant technologies;

·                                          academic expertise in an area of the Company’s operations;

·                                          communications and interpersonal skills; and

·                                          practical and mature business judgment.

These directors also evaluate Board members’ and nominees’ service on the board of other public companies.  Although these directors use these and other criteria to evaluate potential nominees, there are no stated minimum criteria for nominees.  These directors also evaluate candidates identified by their personal contacts and other Board members.

These directors will also consider nominees proposed by stockholders.  Although the Company has no formal policy regarding stockholder nominees, stockholder nominees are viewed in substantially the same manner as other nominees.  The consideration of any candidate for director will be based on the assessment of the individual’s background, skills and abilities, and if such characteristics qualify the individual to fulfill the needs of the Board at that time.  To recommend a prospective nominee for consideration, stockholders should submit the candidate’s name and qualifications to the Company’s Secretary in writing at the address listed above.  There have been no changes to the procedures by which stockholders may recommend nominees to the Board since the date of the Company’s proxy statement for its 2011 annual meeting of stockholders.  The Board annually reviews the requisite skills and characteristics of Board members, as well as the composition of the Board as a whole. This assessment includes a consideration of independence, diversity, skills, experience and industry backgrounds in the context of the needs of the Board and the Company. Directors are expected to exemplify the highest standards of personal and professional integrity; and to constructively challenge management through their active participation and questioning.

Communication with the Board

Due to the historical trend of infrequent communication from current stockholders, the Company does not have formal procedures for stockholder communication with the Board.  Any matter intended for the Board, or for any individual member or members of the Board, should be directed to the Company’s Secretary at the address of the Company indicated above, with a request to forward the same to the intended recipient.  In general, all stockholder communication delivered to the Company’s Secretary for forwarding to the Board or specified Board members will be forwarded in accordance with the stockholder’s instructions, unless the Secretary believes the question or issue may be

8

addressed adequately by the Company’s investor relations department.  However, the Secretary reserves the right to not forward to Board members any abusive, threatening or otherwise inappropriate materials.

Policy Regarding Board Attendance at Stockholders Meetings

Although it has no formal policy requiring attendance, the Company encourages all directors to attend all meetings of stockholders.  All five of the Company’s directors attended the 2011 annual stockholders meeting.

Code of Ethics

All of the Company’s directors and employees are required to abide by the Company’s Code of Business Conduct and Ethics, and the Company’s Chief Executive Officer, Chief Financial Officer, and other senior financial employees are also required to abide by the Company’s Code of Ethics for Senior Financial Employees (together, the “Codes”), which the Company adopted on March 18, 2004 to comply with Nasdaq and SEC requirements to insure that the Company’s business is conducted in a consistently legal and ethical manner.  Both Codes cover all areas of professional conduct, including conflicts of interest, fair dealing and the strict adherence to all laws and regulations applicable to the conduct of the Company’s business.  The full text of the Codes is published on the Company’s website at www.intrusion.com; click on the investor relations tab, and then “Code of Ethics.”  The Company intends to disclose future amendments to, or waivers from, certain provisions of the Codes of Ethics on the Company’s website within four business days following the date of such amendment or waiver.  Upon the written request of any stockholder, the Company will furnish, without charge, a copy of each of the Codes.  This request should be directed to the Company’s Secretary at the address indicated above.

PROPOSAL TWO

PROPOSAL TO APPROVE AMENDMENT TO THE 2005 STOCK INCENTIVE PLAN

The Company has used stock options as a key element of its overall compensation program for employees of the Company.  The Board and the Compensation Committee believe that it is important to have equity-based incentives available to attract and retain quality employees for the Company.  On February 9, 2012, the Board approved, subject to stockholder approval at the Meeting, a proposal to amend the 2005 Plan.  The following descriptions present summaries of (i) the 2005 Plan as it currently exists and (ii) the proposed amendment to the 2005 Plan.

Description of the Existing 2005 Stock Incentive Plan

The 2005 Plan consists of three (3) separate equity incentive programs:

·                  the Discretionary Option Grant Program;

·                  the Stock Issuance Program; and

·                  the Automatic Option Grant Program for non-employee Board members.

The principal features of each program are described below.  The Compensation Committee of the Board will have the exclusive authority to administer the Discretionary Option Grant and Stock Issuance Programs with respect to option grants and stock issuances made to the Company’s executive officers and non-employee Board members and also will have the authority to make option grants and stock issuances under those programs to all other eligible individuals.  However, the Board may at any time appoint a secondary committee of one or more Board members to have separate but concurrent authority with the Compensation Committee to make option grants and stock issuances under those two programs to eligible individuals other than the Company’s executive officers and non-employee directors.

The term “plan administrator”, as used in this summary, will mean the Compensation Committee and any secondary committee, to the extent each committee is acting within the scope of its administrative discretion under the 2005 Plan.  However, neither the Compensation Committee nor any secondary committee may exercise any administrative discretion under the Automatic Option Grant Program.  All grants under Automatic Option Grant Program are made in strict compliance with the express provisions of that program.

9

Issuable Shares

Under the 2005 Plan, 3,400,000 shares of Common Stock have been reserved for issuance, 3,241,500 shares have been granted for issuance, and 2,755,500 option shares are outstanding as of March 30, 2012.

No participant in the 2005 Plan may receive option grants for more than 100,000 shares of Common Stock in total per calendar year, subject to adjustment for subsequent stock splits, stock dividends and similar transactions.  This limitation, together with the fact that option grants under the Discretionary Option Grant Program to its executive officers will be made by the Compensation Committee and will have an exercise price per share equal to the fair market value per share of Common Stock on the date of grant, should ensure that any deductions to which the Company would otherwise be entitled upon the exercise of stock options granted under the Discretionary Option Grant Program or the subsequent sale of the shares purchased under those options will not be subject to the $1 million limitation on the income tax deductibility of compensation paid per executive officer imposed under Section 162(m) of the Internal Revenue Code.

If an option expires or is terminated for any reason before all its shares are exercised, the shares not exercised will be available for subsequent option grants or stock issuances under the 2005 Plan.  In addition, unvested shares issued under the 2005 Plan and subsequently repurchased by the Company at a price not greater than the original exercise price or issue price paid per share will be added back to the number of shares of Common Stock reserved for issuance under the 2005 Plan.  Accordingly, these repurchased shares will be available for reissuance through one or more subsequent option grants or direct stock issuance under the 2005 Plan.

Eligibility

Officers and employees, non-employee Board members and independent contractors in the Company’s service or in the service of its parent or subsidiary companies (whether now existing or subsequently established) will be eligible to participate in the Discretionary Option Grant and Stock Issuance Programs.  Participation in the Automatic Option Grant Program is limited to non-employee members of the Board.

As of April 2, 2012, approximately 28 employees, including four executive officers, three non-employee Board members, and two contractors were eligible to participate in the Discretionary Option Grant and Stock Issuance Programs.  The three non-employee Board members are also eligible to participate in the Automatic Option Grant Program.

Valuation

The fair market value per share of Common Stock on any relevant date under the 2005 Plan will be deemed to be equal to the closing selling price per share on that date on the OTCBB Market.  On March 30, 2012, the fair market value per share determined on this basis was $0.65.

Discretionary Option Grant Program

Grants

The plan administrator will have complete discretion under the Discretionary Option Grant Program to determine which eligible individuals are to receive option grants, the time or times when those grants are to be made, the number of shares subject to each grant, the status of any granted option as either an incentive stock option or a non-statutory option under federal tax laws, the vesting schedule, if any, to be in effect for the option grant and the maximum term for which any granted option is to remain outstanding.

Price and Exercisability

Each granted option will have an exercise price per share not less than 100% of the fair market value on the date of grant of the shares unless otherwise determined by the plan administrator.  No granted option will have a term in excess of ten years.  The shares subject to each option will generally vest in one or more installments over a specified period of service measured from the grant date subject to the optionee’s continued service.  However, one or more options may be structured so that they will be immediately exercisable for any or all of the option shares.  The shares acquired under those options will be subject to repurchase by the Company, at the lower of the exercise price paid per share or the fair market

10

value per share, if the optionee ceases service with the Company prior to vesting in those shares.

The exercise price may be paid in cash or in shares of Common Stock.  Outstanding options may also be exercised through a same-day sale program pursuant to which a designated brokerage firm is to effect an immediate sale of the shares purchased under the option and pay to the Company, out of the sale proceeds available on the settlement date, sufficient funds to cover the exercise price for the purchased shares, plus all applicable withholding taxes.

Termination of Service

Upon cessation of service with the Company, the optionee will have a limited period of time in which to exercise any outstanding option to the extent exercisable for vested shares.  The plan administrator will have complete discretion to extend the period following the optionee’s cessation of service during which his or her outstanding options may be exercised and/or to accelerate the exercisability or vesting of such options in whole or in part.  This discretion may be exercised at any time while the options remain outstanding, whether before or after the optionee’s actual cessation of service.

Cancellation/Regrant Program

The plan administrator will have the authority to effect, with the consent of the affected option holders, the cancellation of outstanding options under the Discretionary Option Grant Program in return for the grant of new options for the same or a different number of option shares with an exercise price per share based upon the fair market value of the Common Stock on the new grant date.

Stock Issuance Program

Shares of the Company’s Common Stock may be issued under the Stock Issuance Program at a price per share not less than 100% of their fair market value on the date of grant, payable in cash.  In addition, shares may be issued as a bonus for past services without any cash outlay required of the recipient.  Further, shares of Common Stock may be issued under the Stock Issuance Program pursuant to share right awards which entitle the recipients to receive those shares upon the attainment of designated performance goals or completion of a specified service period.  The plan administrator will have complete discretion under this program to determine which eligible individuals are to receive these stock issuances or share right awards, the time or times when these issuances or awards are to be made, the number of shares subject to each issuance or award and the vesting schedule to be in effect for the stock issuance or share rights award (subject to the limitations of Section 162(m) of the Internal Revenue Code described above).

The shares issued may be fully and immediately vested upon issuance or may vest upon the recipient’s completion of a designated service period or upon the attainment of pre-established performance goals.  The plan administrator will, however, have the discretionary authority at any time to accelerate the vesting of any and all unvested shares outstanding under the Stock Issuance Program.

Any unvested shares for which the requisite service requirement or performance objective is not obtained must be surrendered to the Company for cancellation, and the participant will not have any further stockholder rights with respect to those shares.  However, for shares issued for cash or cash equivalents, including a promissory note, the Company will repay the participant the cash amount paid for the surrendered shares without interest and/or shall cancel the unpaid principal balance of any promissory note delivered in payment of those shares.

Outstanding share right awards under the Stock Issuance Program will automatically terminate, and no shares of Common Stock will actually be issued in satisfaction of those awards, if the performance goals established for such awards are not attained.  The plan administrator, however, will have the discretionary authority to issue shares of Common Stock in satisfaction of one or more outstanding share right awards as to which the designated performance goals are not attained.

However, in order to assure that the compensation attributable to one or more stock issuances under the program will qualify as performance-based compensation which will not be subject to the $1 million limitation on the income tax deductibility of the compensation paid per executive officer which is imposed under Internal Revenue Code Section 162(m), the plan administrator shall, in its sole discretion, provide that those particular issuances will be

11

contingent upon the actual attainment of certain pre-established performance goals based on one or more of the following criteria:

·                  return on total stockholder equity;

·                  earnings per share of Common Stock;

·                  net income (before or after taxes);

·                  earnings before interest, taxes, depreciation and amortization;

·                  sales or revenues;

·                  return on assets, capital or investment;

·                  market share;

·                  cost reduction goals;

·                  budget comparisons;

·                  implementation or completion of critical projects or processes;

·                  customer satisfaction;

·                  any combination of, or a specified increase in, any of the foregoing; and

·                  the formation of joint ventures, research or development collaborations, or the completion of other corporate transactions.

In addition, performance goals may be based upon the attainment of specified levels of the Company’s performance under one or more of the measures described above relative to the performance of other entities and may also be based on the performance of any of its business units or divisions or subsidiaries.  Performance goals may include a minimum threshold level of performance below which no award will be earned, levels of performance at which specified portions of an award will be earned and a maximum level of performance at which an award will be fully earned.

Automatic Option Grant Program

Grant

Under the Automatic Option Grant Program of the 2005 Plan, eligible non-employee Board members receive a series of option grants over their period of Board service.  Each non-employee Board member will, at the time of his or her initial election or appointment to the Board, receive an option grant for 10,000 shares of Common Stock, provided that individual has not previously been employed by the Company in the preceding six months.  In addition, on the date of each annual stockholders meeting, each individual who is to continue to serve as a non-employee Board member will automatically be granted an option to purchase 5,000 shares of Common Stock, provided he or she has served as a non-employee Board member for at least six months.  There will be no limit on the number of such 5,000-share option grants any one eligible non-employee Board member may receive over his or her period of continued Board service, and non-employee board members who have previously been one of the Company’s employees will be eligible to receive one or more such annual grants over their period of Board service.

Option Terms

Each automatic grant will have an exercise price per share equal to 100% of the fair market value per share of the Company’s Common Stock on the grant date and will have a maximum term of ten years, subject to earlier termination following the optionee’s cessation of Board service.  Each automatic option will vest in three successive equal annual installments upon the optionee’s completion of each year of Board service measured from the grant date.  Following the optionee’s cessation of Board service for any reason, each option will remain exercisable for a 12-month period and may be exercised during that time for any or all shares in which the optionee is vested at the time of the cessation of Board service.

General Provisions

Acceleration

In the event that the Company is acquired by merger or asset sale or its stockholders sell more than 50% of the Company’s outstanding voting stock pursuant to a successful tender offer, each outstanding option under the

12

Discretionary Option Grant Program that is not to be assumed or replaced by the successor corporation or otherwise continued in effect will automatically accelerate in full, and all unvested shares outstanding under the Discretionary Option Grant and Stock Issuance Programs will immediately vest, except to the extent the Company’s repurchase rights with respect to those shares are to be assigned to the successor corporation or otherwise continued in effect.  The plan administrator will also have the authority to grant options which will immediately vest upon an acquisition of the Company, whether or not those options are assumed by the successor corporation.

The plan administrator is also authorized under the Discretionary Option Grant and Stock Issuance Programs to grant options and to structure repurchase rights so that the shares subject to those options or repurchase rights will immediately vest upon an acquisition of the Company by merger or asset sale, the successful completion of a tender offer for more than 50% of the Company’s outstanding voting stock or a proxy contest for the election of Board members.  This accelerated vesting may occur either at the time of the transaction or proxy contest or upon the subsequent involuntary termination of the individual’s service within a designated period not to exceed 18 months following the transaction or proxy contest.

The shares subject to each option under the Automatic Option Grant will immediately vest upon an acquisition of the Company by merger or asset sale, the successful completion of a tender offer for more than 50% of the Company’s outstanding voting stock or a proxy contest for the election of Board members.

The acceleration of vesting in the event of a change in the ownership or control of the Company may be seen as an anti-takeover provision and may have the effect of discouraging a merger proposal, a takeover attempt or other efforts to gain control of the Company.

Stockholder Rights and Option Transferability

No optionee will have any stockholder rights with respect to the option shares until he or she has exercised the option and paid the exercise price for the purchased shares.  Options will generally not be assignable or transferable other than by will or the laws of inheritance following the optionee’s death, and during the optionee’s lifetime, the option may only be exercised by the optionee.  However, the plan administrator may structure one or more non-statutory options under the 2005 Plan so that those options will be transferable during the optionee’s lifetime to one or more members of the optionee’s family or to a trust established for one or more such family members or to the optionee’s former spouse, to the extent such transfer is in connection with the optionee’s estate or pursuant to a domestic relations order.  The optionee may also designate one or more beneficiaries to automatically receive his or her options at death.

Changes in Capitalization

Should any change be made to the Common Stock issuable under the 2005 Plan by reason of any stock split, stock dividend, recapitalization, combination of shares, exchange of shares or other change affecting the outstanding Common Stock as a class without the Company’s receipt of consideration, then appropriate adjustments will be made to:

·                  the maximum number and/or class of securities issuable under the 2005 Plan;

·                  the number and/or class of securities for which any one person may be granted options and direct stock issuances per calendar year under the 2005 Plan;

·                  the number and/or class of securities for which grants are to be made under the Automatic Option Grant Program to new or continuing non-employee Board members; and

·                  the number and/or class of securities and price per share in effect under each outstanding option.

These adjustments to the outstanding options will be effected in a manner which will preclude the enlargement or dilution of rights and benefits under those options.

Financial Assistance

The plan administrator may institute a loan program to assist one or more participants in financing the exercise of outstanding options under the Discretionary Option Grant Program or the purchase of shares under the Stock Issuance Program through full-recourse interest-bearing promissory notes to the extent permitted by law.  However, the maximum

13

amount of financing provided any participant may not exceed the cash consideration payable for the issued shares plus all applicable taxes incurred in connection with the acquisition of those shares.

Special Tax Election

The plan administrator may provide one or more holders of options or unvested share issuances under the 2005 Plan with the right to have the Company withhold a portion of the shares otherwise issuable to these individuals in satisfaction of the withholding taxes to which these individuals become subject in connection with the exercise of those options or the vesting of those shares.  Alternatively, the plan administrator may allow these individuals to deliver previously acquired shares of Common Stock in payment of such withholding tax liability.

Amendment and Termination

The Board may amend or modify the 2005 Plan at any time, subject to any required stockholder approval pursuant to applicable laws and regulations.  Unless sooner terminated by the Board, the 2005 Plan will terminate on the earliest of (1) June 14, 2015, (2) the date on which all shares available for issuance under the 2005 Plan have been issued as fully-vested shares or (3) the termination of all outstanding options in connection with certain changes in control or ownership of the Company.

Federal Income Tax Consequences

Option Grants

Options granted under the Discretionary Option Grant Program may be either incentive stock options which satisfy the requirements of Section 422 of the Internal Revenue Code or non-statutory options, which are not intended to meet those requirements.  All options granted under the Automatic Option Grant Programs will be non-statutory options.  The federal income tax treatment for the two types of options differs as follows:

Incentive Stock Options.  The optionee recognizes no taxable income at the time of the option grant, and no taxable income is recognized for federal income tax purpose at the time the option is exercised, although taxable income may arise at that time for alternative minimum tax purposes.  The optionee will, however, recognize taxable income in the year in which the purchased shares are sold or otherwise made the subject of a taxable disposition.  For federal income tax purposes, dispositions are divided into two categories:  (1) qualifying and (2) disqualifying.  A qualifying disposition occurs if the sale or other disposition is made after the optionee has held the shares for more than two years after the option grant date and more than one year after the exercise date.  If either of these two holding periods is not satisfied, then a disqualifying disposition will result.

Upon a qualifying disposition, the optionee will recognize long-term capital gain in an amount equal to the excess of (1) the amount realized upon the sale or other disposition of the purchased shares over (2) the exercise price paid for the shares.  If there is a disqualifying disposition of the shares, then generally, the excess of (1) the fair market value of those shares on the exercise date over (2) the exercise price paid for over the optionee’s tax basis in the purchased shares (which includes any ordinary income recognized as a result of the disqualifying disposition) the shares will be taxable as ordinary income to the optionee.  Any excess of the amount realized upon the disqualifying disposition will be recognized as a capital gain by the optionee.  If the amount realized upon the disqualifying disposition is less than the fair market value of the purchased shares on the exercise date, then the amount of ordinary income that the optionee would recognize is the excess, if any, of the amount realized upon the sale of other disposition of the purchased shares over the exercise price paid for such shares.

If the optionee makes a disqualifying disposition of the purchased shares, then the Company will be entitled to an income tax deduction, for the taxable year in which such disposition occurs, equal to the amount of ordinary income recognized by the optionee.  The Company will not be entitled to any income tax deduction if the optionee makes a qualifying disposition of the shares.

Non-Statutory Options.  No taxable income is recognized by an optionee upon the grant of a non-statutory option.  The optionee will in general recognize ordinary income, in the year in which the option is exercised, equal to the excess of the fair market value of the purchased shares on the exercise date over the exercise price paid for the shares, and the

14

optionee will be required to satisfy the tax withholding requirements applicable to such income.

If the shares acquired upon exercise of the non-statutory option are unvested and subject to repurchase by the Company in the event of the optionee’s termination of service prior to vesting in those shares, then the optionee will not recognize any taxable income at the time of exercise but will have to report as ordinary income, as and when the shares vest and this repurchase right lapses, an amount equal to the excess of (1) the fair market value of the shares on the date the shares vest and the repurchase right lapses over (2) the exercise price paid for the shares.  The optionee may, however, elect under Section 83(b) of the Internal Revenue Code to include as ordinary income in the year of exercise of the option an amount equal to the excess of (1) the fair market value of the purchased shares on the exercise date over (2) the exercise price paid for such shares.  If the Section 83(b) election is made, the optionee will not recognize any additional income as and when the shares vest and the repurchase right lapses.

The Company will be entitled to an income tax deduction equal to the amount of ordinary income recognized by the optionee with respect to the exercised non-statutory option.  The deduction will in general be allowed for the Company’s taxable year in which the ordinary income is recognized by the optionee.

Direct Stock Issuances

The federal income tax principles applicable to direct stock issuances under the 2005 Plan will be substantially the same as those summarized above for the exercise of unvested non-statutory options, if the shares are not vested.  If the shares are vested, the recipient of the shares will recognize taxable income upon receipt of the shares in the amount equal to the fair market value of the shares at the time of receipt, less the amount, if any, paid for the shares.

Deductibility of Executive Compensation

The Company anticipates that any compensation deemed paid by it in connection with the disqualifying dispositions of incentive stock option shares or the exercise of non-statutory options with exercise prices equal to the fair market value of the option shares on the grant date will qualify as performance-based compensation for purposes of Internal Revenue Code Section 162(m) and will not have to be taken into account for purposes of the $1 million limitation per covered individual on the deductibility of the compensation paid to certain of its executive officers.  Accordingly, all compensation deemed paid with respect to those options will remain deductible by the Company without limitation under Internal Revenue Code Section 162(m).

Accounting Treatment

The Company accounts for stock options using guidance from FASB ASC Topic 718 which requires all share-based payments to employees, including grants of employee stock options, to be recognized in the financial statements based on their fair values.

Interests of Officers and Directors

The Company’s executive officers, including the employee director nominees, Mr. Paxton and Mr. Head, and the Company’s non-employee director nominees, Mr. Bucy, Mr. Gero and Mr. Johnston, are entitled to participate in the 2005 Plan and may receive option grants and stock issuances under the Discretionary Option Grant Program and the Stock Issuance Program.  In addition, the non-employee director nominees will receive option grants under the Automatic Option Program as set forth above under “New Plan Benefits.”

Description of Proposed Amendment to the 2005 Stock Incentive Plan

Assuming approval by the stockholders of the Company of the proposed amendment to the 2005 Plan, the Company intends to amend the 2005 Plan.  Stock options under the Amended 2005 Plan would continue to vest under conditions determined by the Compensation Committee.  The material amendment to be effected pursuant to the Amended 2005 Plan is as follows:

The Amended 2005 Plan would increase the total number of shares available under the 2005 Plan to be issued upon the exercise of stock options granted by 300,000 shares to 3,700,000 shares of Common Stock.  This amendment would increase the shares available for issuance as of March 30, 2012 from 547,499 to 847,499 shares.  As noted

15

previously, the proceeds received by the Company upon exercise of stock options will increase the Company’s cash and equity balances.

The Amended 2005 Plan would continue to be administered by the Compensation Committee.  A copy of the Amended 2005 Plan is included in this document under Appendix A.

As of March 30, 2012, no stock options had been granted, and no shares of Common Stock had been issued, on the basis of the share increase which is the subject of this Proposal.

New Plan Benefits

Because awards granted under the Amended 2005 Plan are at the discretion of the Compensation Committee, the awards that will be granted in the future are not currently determinable.  The Company has not made or entered into any commitments, agreements or understandings related to any future awards excepts as described in the section titled “Automatic Option Grant Program.” For the year 2011, a total of 408,000 shares were awarded as incentive options, 240,000 or 59% were awarded to “Named Executive Officer Group” and 168,000 shares, or 41% of the total awarded was awarded to “Non-Executive Officer Named Employee Group” which does not include 15,000 shares granted to non-employee directors.  Plan awards for fiscal year 2011 are set forth in the following table:

Stockholder Approval

The affirmative vote of at least a majority of the outstanding shares of Common Stock present in person or by Proxy at the Meeting and entitled to vote is required for approval of the Amended 2005 Plan.  Should such stockholder approval not be obtained, then the 300,000 share increase to the share reserve under the 2005 Plan will not occur and no options or stock issuances will be made on the basis of such increases.  The 2005 Plan will, however, continue in effect, and option grants may continue to be made under the 2005 Plan until all the shares available for issuance under the 2005 Plan have been issued pursuant to such option grants.

The Board of Directors recommends a vote “FOR” this proposal.

PROPOSAL THREE
RATIFICATION OF THE APPOINTMENT
OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board has appointed Whitley Penn LLP to serve as independent auditors of the Company and to audit its consolidated financial statements for fiscal year 2012, subject to ratification by the Company’s stockholders at the Meeting.  Whitley Penn LLP has served as the Company’s Independent Registered Public Accounting Firm since July 2009.  To the knowledge of management of the Company, neither such firm nor any of its members has any direct or material indirect financial interest in the Company, nor any connection with the Company in any capacity other than as independent auditors.

Although stockholder ratification and approval of this appointment is not required by the Company’s bylaws or otherwise, in keeping with the Company’s policy that its stockholders should be entitled to a voice in this regard and as a matter of good corporate practice, the Board is seeking ratification of this appointment.  If the appointment is not ratified, the Board must then determine whether to appoint other auditors prior to the end of the current fiscal year.  In such case, the opinions of stockholders will be taken into consideration.

Fees Paid to Independent Registered Public Accounting Firm

The Audit Committee has reviewed the following audit and non-audit fees the Company has paid to Whitley Penn LLP for 2011 and 2010 for purposes of considering whether such fees are compatible with maintaining the auditor’s independence.  The policy of the Audit Committee is to pre-approve all audit and non-audit services performed by Whitley Penn LLP before the services are performed, including all of the services described below under “Audit-Related Fees,” “Tax Fees” and “All Other Fees” below.

Audit Fees.  Estimated fees billed for service rendered by our Accounting Firm for the reviews of Forms 10-Q and for the audit of the consolidated financial statements of the Company were $88,500 for 2011 and 2010.

Audited-Related Fees.  Aggregate fees billed for all audit-related services rendered by our Accounting Firm were $0 for 2011 and 2010.

Tax Fees.  Aggregate fees billed for permissible tax services rendered by our Accounting Firm consisted of $16,000 for 2011 and 20010.  These amounts include tax strategy services, preparation of sales tax returns, preparation of federal and state income tax returns, preparation of property tax and franchise tax returns and international tax issues.

All Other Fees.  Aggregate fees billed for all other services rendered by our Accounting Firm consisted of $0 for 2011 and $5,000 for 2010.  The services billed for 2010 were related to other reviewed materials.

Representatives of Whitley Penn LLP are expected to be in attendance at the Meeting and will be afforded the opportunity to make a statement.  The representatives will also be available to respond to appropriate questions.

The enclosed Proxy will be voted as specified, but if no specification is made, it will be voted “for” the adoption of the resolution of ratification.

The Board recommends a vote “FOR” this proposal.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL
OWNERS AND MANAGEMENT

The following table sets forth information regarding the beneficial ownership of the Common Stock as of April 2, 2012, unless otherwise indicated, by (1) each person known by the Company to be the beneficial owner of more than 5% of the outstanding shares of Common and Preferred Stock, (2) each director of the Company, (3) the Company’s current executive officers and (4) all current directors and executive officers of the Company as a group.  The persons and entities named in the table have sole voting and investment power with respect to all such shares owned by them, unless otherwise indicated.

*      Represents beneficial ownership of less than 1% of the outstanding shares of Common Stock.

(1)           The addresses of the persons or entities shown in the foregoing table who are beneficial owners of more than 5% of the Common Stock and/or Preferred Stock are as follows:  G. Ward Paxton, T. Joe Head, Michael L. Paxton, Mark A. Paxton and Julie Paxton Puckett, 1101 East Arapaho Road, Suite 200, Richardson, Texas 75081; Walter Schenker, 7 Century Drive, Suite 201, Parsippany, NJ 07054; and Craig D. Hodges, 2905 Maple Avenue, Dallas, TX 75201.

(2)           Beneficial ownership is calculated in accordance with the rules of the SEC in accordance with Rule 13d-3(d)(1) of the Exchange Act.  Percentage of beneficial ownership is based on 11,972,017 shares of Common Stock and 220,000 shares of 5% Preferred Stock outstanding as of March 30, 2012.  In computing the number of shares beneficially owned by a person and the percentage ownership of that person, shares of Common Stock subject to options or warrants held by that person that are currently exercisable or will become exercisable within 60 days following March 30, 2012 are deemed outstanding.  However, these shares are not deemed outstanding for the purpose of computing the percentage ownership of any other person.  Unless otherwise indicated in the footnotes to this table, the persons and entities named in the table have sole voting and sole investment power with respect to all shares beneficially owned, subject to community property laws where applicable.

Certain shares of Common Stock shown as beneficially owned are issuable upon conversion of the 5% Preferred Stock the Company issued in a private placement on March 25, 2004.  Under the terms of these shares of 5% Preferred Stock, the shares of 5% Preferred Stock are convertible only to the extent that the number of shares of Common Stock issuable pursuant to those securities, together with the number of shares of Common Stock owned by the relevant person and its affiliates (but not including shares of Common Stock underlying unconverted portions of the 5% Preferred Stock) would not exceed 9.9% of the then outstanding Common Stock, as determined in accordance with Section 13(d) of the Exchange Act.  In addition, certain shares of Common Stock shown as beneficially owned are issuable upon the conversion of Series 2 5% Preferred Stock issued in a private placement

18

on March 28, 2005.  Under the terms of the Series 2 5% Preferred Stock, the shares are convertible only to the extent that the number of shares of Common Stock issuable upon conversion thereof and upon the exercise of the warrants issued in such private placement, together with the number of shares of Common Stock owned the relevant person and its affiliates (but not including shares of Common Stock underlying unconverted portions of the Series 2 preferred stock or unexercised portions of the warrants) would not exceed 4.99% of the then outstanding Common Stock as determined in accordance with Section 13(d) of the Exchange Act.  However, this restriction does not apply to any holder of the Series 2 Preferred Stock who is one of the Company’s directors or officers.  Similar restrictions apply to the conversion of the Series 3 5% Preferred Stock and Private Placement Warrants.

(3)           Includes the equivalent of approximately 4,400 shares held by Mr. G. Ward Paxton in the Intrusion Stock Fund in the Intrusion 401(k) Savings Plan.

(6)           Includes the equivalent of 27,523 shares that may be issued upon conversion of Series 3 5% Preferred Stock, the equivalent of 60,000 shares that may be issued upon conversion of Series 2 5% Preferred Stock and 95,419 shares that may issued upon conversion of 5% Preferred Stock.  Also includes 37,501 shares that Mr. Gero may acquire upon exercise of options that are currently exercisable or will become exercisable within 60 days of March 30, 2012.

(7)           Includes 35,001 shares that Mr. Johnston may acquire upon exercise of options that are currently exercisable or will become exercisable within 60 days of March 30, 2012.

Summary Compensation Information

The following table sets forth certain summary information regarding all cash compensation earned by the Company’s Chief Executive Officer, Chief Financial Officer and each of the Company’s other two executive officers for the last three fiscal years in all capacities in which they served the Company and its subsidiaries for such period.  The individuals listed below shall be referred to as the “Named Executive Officers”.

2011 SUMMARY COMPENSATION TABLE (4)

(1)           Represents bonus compensation and/or commission earned during the fiscal year indicated, a portion of which may have been or will be paid during the subsequent fiscal year.

(2)           Represents the aggregate grant date fair value computed in accordance with FASB ASC Topic 718. The FASB ASC Topic 718 full grant date fair value and will be expensed and reported as the option vests for each Named Executive Officer. A complete discussion of the assumptions used to calculate such values can be found in the Company’s 2011 Annual Report on Form 10-K, which accompanies this Proxy Statement.

(3)           This amount includes the annual employer matching contributions under the Company’s tax qualified Section 401(k) Savings Plan for Mr. G. Ward Paxton, Mr. Michael L. Paxton, T. Joe Head and Garry L. Hemphill, respectively.

(4)           No stock awards were paid, no non-equity incentive plan compensation was paid, and no pension or non-qualified deferred compensation earnings were charged to the Named Executive Officers for the last three fiscal years.  These columns have been omitted from the table.

Base Salary

The salaries of the executive officers, including the Chief Executive Officer, are determined annually by the Compensation Committee with reference to the following without specific weighting:

·                  salaries paid to executives with similar responsibilities at companies of a comparable size and sales volume, primarily in the high technology industry;

·                  each officer’s performance; and

·                  the Company’s overall financial results.

21

The Compensation Committee believes that other companies likely compete with the Company for executive talent and that the Company must offer salaries within a competitive market range to attract and retain talented executives.  However, the Compensation Committee manages salaries for the executive group as a whole in a conservative fashion in order to place more emphasis on incentive compensation.  Compensation paid to our executive officers is low compared to industry averages; therefore, as a result of positive Company performance, the Compensation Committee increased the base salaries of the executive officers in the range of 9% to 24% during 2011.  After the increases, the Company believes the base salaries of its executive officers remain lower than the median compensation in effect for comparable positions in the surveyed data.  The Company does not consider the performance of the comparison group in determining compensation of its executive officers.

Bonus

To reinforce the attainment of corporate objectives, the Compensation Committee believes that a substantial portion of the potential annual compensation of each executive officer should be in the form of short-term, variable incentive pay.  The incentive cash bonus program for executives is established annually by the Compensation Committee based upon the Company’s achievement of sales and/or net income targets established at the beginning of the fiscal year.  The incentive plan for executives requires a threshold level of Company financial performance before any incentives are awarded.  Once the threshold objective for sales and/or net income of a fiscal year is reached, specific formulas are in place to calculate the actual incentive payment for each executive for such year.

At the beginning of fiscal year 2011, the Compensation Committee adopted the 2011 management incentive plan. Under the terms of the 2011 management incentive plan, the bonus payable to each executive officer was based on sales targets.

Bonuses Awarded

In fiscal year 2011, the Company did not achieve its threshold level of sales; thus, non-sales executives, including the Named Executive Officers, did not receive any incentive bonus awards.  Certain employees in the sales organization, received incentive sales commission in fiscal 2011 based upon the Company’s sales.

Stock Option and Equity Incentive Programs

The goal of the Company’s equity-based incentive awards is to align the interests of executive officers with the Company’s stockholders.  The Compensation Committee determines the value allocated to equity-based incentives according to each executive’s position within the Company, individual performance, contributions to achievement of corporate objectives and related factors, and grants stock options to create a meaningful opportunity for stock ownership.  Because of the direct relationship between stock option value and the market price, it is believed that granting options is the best method to motivate executives to mirror the concerns of other stockholders.

Stock Options Granted

The Company grants stock option awards to the executive officers and key employees in order to retain their services and increase their performance potential to help attain long-term goals of the Company. However, there is no set formula for the granting of awards to individual executives or employees. In each of the past three fiscal years, 2011, 2010 and 2009, the Company has granted stock options to purchase 408,000, 474,000 and 496,000 shares of the Company’s Common Stock, respectively. Of this amount, 240,000, 300,000 and 300,000 shares have been granted to the Named Executive Officers, and the balance has been granted to other key employees and non-employee directors in 2011, 2010 and 2009, respectively.  During fiscal year 2011, a total of twenty-nine employees, two non-employees, and three non-employee directors received stock options to purchase an aggregate of 3.4% of the outstanding shares of Common Stock, including all of the four Named Executive Officers, who received stock options to acquire an aggregate of 240,000 shares or 59% of the total options granted in fiscal 2011.

22

Timing of Grants

Stock awards to executive officers and other key employees are typically granted annually in conjunction with the review of the individual performance. This review typically takes place in January.  Stock option awards are granted to non-employee directors on the date of the annual meeting of stockholders, in accordance with the terms of the 2005 Plan. Grants to newly hired employees are effective on the first Compensation Committee meeting following the employee’s first day of employment, after approval by the committee. The exercise price of all stock options is set at the then current day’s closing price of the Common Stock.

Stock Ownership Guidelines

The Company does not have any standard stock ownership guidelines. However, all executives are encouraged to retain stock options and other shares that they directly own.

Perquisites

The Company limits the perquisites that are made available to executive officers.  The Company does not have a pension program for executives or employees.

The perquisites provided by the Company in fiscal year 2011 are as follows. All employees who participated in the Company’s 401(k) plan may receive up to $1,750 in matching funds. All of the Named Executive Officers who participated in the 401(k) plan received matching funds. The health and life insurance plans are the same for all employees. In general, all employees’ base health premiums are paid 100% and the employee pays approximately 40% of the health premiums for dependents. All employees are also provided life insurance up to $10,000. This policy is the same for all employees, including executive officers.

Grants of Plan-Based Awards During Fiscal Year 2011

The following table provides information related to options to acquire shares of Common Stock granted to the Named Executive Officers during fiscal year 2011.  The Company did not grant any stock awards or non-equity incentive plan units during fiscal year 2011.

Employment Agreements

Neither the Company nor its subsidiaries has any employment agreements with any of its Named Executive Officers.

director. Refer to Note 9, “Stock Options”, in the Notes to Consolidated Financial Statements included in the Annual Report on Form 10-K filed on March 30, 2012 for the relevant assumptions used to determine the valuation of the stock option awards.

(4)                                  The following are the aggregate number of option awards outstanding that have been granted to each of the non-employee directors as of December 31, 2011: Mr. Bucy — 42,500; Mr. Gero — 42,500; and Mr. Johnston — 42,500.

Overview of Compensation and Procedures

The Compensation Committee reviews the level of compensation of non-employee Directors on an annual basis. The Company has historically used data from a number of different sources to determine the compensation for non-employee Directors. Some examples of the data used include:

·      publicly available data describing director compensation in peer companies; and

·      survey data collected by the Company.

We compensate non-employee members of the Board through a mixture of cash and equity-based compensation. Each non-employee Director receives a cash retainer fee of $1,200 per month.  Each non-employee Director also receives a fee of $1,200 for each meeting of the Board attended (excluding telephonic meetings) and for each meeting of a committee of the Board attended (exclusive of committee meetings held on the same day as Board meetings).  Each non-employee Director also receives a fee of $600 for each telephonic meeting attended.  Each non-employee Director is also reimbursed for all reasonable expenses incurred in attending such meetings.  No Director who is an employee of the Company receives any fees for service as a Director.  However, G. Ward Paxton and T. Joe Head each earned compensation for his services to the Company as an employee as set forth in the Summary Compensation Table.  Mr. G. Ward Paxton received a stock option grant for 80,000 shares at a price of $0.77 per share during 2011. Mr. T. Joe Head received a stock option grant for 80,000 shares at a price of $0.70 per share during 2011. The options are detailed on the “2011 Grants of Plan-Based Awards Table” in this proxy statement.  Neither Mr. Paxton nor Mr. Head received any additional fees for his services as a Director.

Under the Automatic Option Grant Program of the 2005 Plan, each non-employee Director will automatically be granted an option to purchase 10,000 shares of Common Stock upon joining the Board and an option to purchase 5,000 shares of Common Stock on the date of each annual stockholder meeting as long as the director has served at least six months prior to the date of grant.

CERTAIN TRANSACTIONS WITH MANAGEMENT

February 9, 2012 Promissory Note

On February 9, 2012, the Company entered into an unsecured revolving promissory note to borrow up to $2,200,000 from G. Ward Paxton, the Company’s Chairman, President and Chief Executive Officer.  Under the terms of the note, the Company may borrow, repay and reborrow on the loan as needed up to an outstanding principal balance due of $2,200,000 at any given time.  Amounts the Company borrows under the note accrue interest at a floating rate per annum equal to the announced prime rate of Silicon Valley Bank plus 1% and are unsecured.  All outstanding principal and accrued but unpaid interest are due on March 31, 2013.  At December 31, 2011, there was a principal balance due to Mr. Paxton of $1,530,000 under the terms of the promissory note.

During 2011 and up until March 31, 2012, there have been no other transactions, or currently proposed transactions, between the Company and any of its executive officers, directors or 5% beneficial holders, or member of the immediate family of the foregoing persons, in which one of the foregoing individuals or entities had an interest of more than $120,000.

26

changes in ownership with the SEC.  Such persons are required by SEC regulation promulgated pursuant to the Exchange Act to furnish the Company with copies of all Section 16(a) report forms they file with the SEC.

Based solely on its review of the copies of such report forms received by it with respect to fiscal year 2011, the Company believes that all filing requirements applicable to its directors, officers and persons who own more than 10% of a registered class of the Company’s equity securities have been timely complied with in accordance with Section 16(a) of the Exchange Act.

D.                         Service on the Primary Committee or the Secondary Committee shall constitute service as a Board member, and members of each such committee shall accordingly be entitled to full indemnification and reimbursement as Board members for their service on such committee.  No member of the Primary Committee or the Secondary Committee shall be liable for any act or omission made in good faith with respect to the Plan or any option grants or stock issuances under the Plan.

E.                           Administration of the Automatic Option Grant Program shall be self-executing in accordance with the terms of that program, and no Plan Administrator shall exercise any discretionary functions with respect to any option grants or stock issuances made under that program.

IV.                              ELIGIBILITY

A.                        The persons eligible to participate in the Discretionary Option Grant and Stock Issuance Programs are as follows:

1.                                       Employees,

2.                                        non-Employee members of the Board or the board of directors of any Parent or Subsidiary, and

D.                         The individuals who shall be eligible to participate in the Automatic Option Grant Program shall be limited to (1) those individuals who first become non-Employee Board members on or after the Plan Effective Date, whether through appointment by the Board or election by the Corporation’s stockholders, and (2) those individuals who continue to serve as non-Employee Board members at one or more Annual Stockholders’ Meetings held on or after the Plan Effective Date, provided that individual has been a non-Employee Board member for at least six months.

V.                                    STOCK SUBJECT TO THE PLAN

A.                        The stock issuable under the Plan shall be shares of authorized but unissued or reacquired Common Stock, including shares repurchased by the Corporation on the open market.  The number of shares of Common Stock reserved for issuance over the term of the Plan shall not exceed 3,700,000 shares.

B.                          No one person participating in the Plan may receive options and direct stock issuances pursuant to the Plan for more than 100,000 shares of Common Stock in the aggregate per calendar year.

C.                          Shares of Common Stock subject to outstanding options granted under the Plan shall be available for subsequent issuance under the Plan to the extent (1) those options expire or terminate for any reason prior to exercise in full or (2) the options are cancelled in accordance with the cancellation-regrant provisions of the Discretionary Option Grant Program.  Unvested shares issued under the Plan and subsequently cancelled or repurchased by the Corporation pursuant to the Corporation’s repurchase rights under the Plan shall be added back to the number of shares of Common Stock reserved for issuance under the Plan and shall accordingly be available for reissuance through one or more subsequent option grants or direct stock issuances under the Plan.  However, should the exercise price of an option granted pursuant to the Plan be paid with shares of Common Stock or should shares of Common Stock otherwise issuable pursuant to the Plan be withheld by the Corporation in satisfaction of the withholding taxes incurred in connection with the exercise of an option or the vesting of a stock issuance made pursuant to the Plan, then the number of shares of Common Stock available for issuance pursuant to the Plan shall be reduced by the gross number of shares for which the option is exercised or which vest under the stock issuance, and not by the net number of shares of Common Stock issued to the holder of such option or stock issuance.

D.                         If any change is made to the Common Stock by reason of any stock split, stock dividend, recapitalization, combination of shares, exchange of shares or other change affecting the outstanding Common Stock as a class without the Corporation’s receipt of consideration,

A-3

appropriate adjustments shall be made by the Plan Administrator to (1) the maximum number and/or class of securities issuable pursuant to the Plan, (2) the maximum number and/or class of securities for which any one person may be granted options and direct stock issuances pursuant to the Plan per calendar year, (3) the number and/or class of securities for which grants are subsequently to be made pursuant to the Automatic Option Grant Program to new and continuing non-Employee Board members, and (4) the number and/or class of securities and the exercise price per share in effect under each outstanding option granted pursuant to the Plan.  Such adjustments to the outstanding options are to be effected in a manner that shall preclude the enlargement or dilution of rights and benefits under such options.  The adjustments determined by the Plan Administrator shall be final.

E.                           Outstanding awards granted pursuant to the Plan shall in no way affect the right of the Corporation to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets.

E.                           Repurchase Rights. The Plan Administrator shall have the discretion to grant options that are exercisable for unvested shares of Common Stock.  Should the Optionee cease Service while such shares are unvested, the Corporation shall have the right to repurchase any or all of those unvested shares at the exercise price paid per share.  The terms upon which such repurchase right shall be exercisable (including the period and procedure for exercise and the appropriate vesting schedule for the purchased shares) shall be established by the Plan Administrator and set forth in the document evidencing such repurchase right.

F.                           Limited Transferability of Options.  During the lifetime of the Optionee, options shall be exercisable only by the Optionee and shall not be assignable or transferable other than by will or by the laws of inheritance following the Optionee’s death.  However, a Non-Statutory Option may be assigned in whole or in part during the Optionee’s lifetime to one or more members of the Optionee’s family or to a trust established exclusively for one or more such family members or to the Optionee’s former spouse, to the extent such assignment is in connection with the Optionee’s estate plan or pursuant to a domestic relations order.  The assigned portion may only be exercised by the person or persons who acquire a proprietary interest in the option pursuant to the assignment.  The terms applicable to the assigned portion shall be the same as those in effect for the option immediately prior to such assignment and shall be set forth in such documents issued to the assignee as the Plan Administrator may deem appropriate.  Notwithstanding the foregoing, the Optionee may also designate one or more persons as the beneficiary or beneficiaries of his or her outstanding options granted pursuant to the Plan, and those options shall, in accordance with such designation, automatically be transferred to such beneficiary or beneficiaries upon the Optionee’s death prior to the Expiration Date of those options.  Such beneficiary or beneficiaries shall take the transferred options subject to all the terms and conditions of the applicable agreement evidencing each such transferred option, including (without limitation) the limited time period during which the option may be exercised following the Optionee’s death.

II.                                   INCENTIVE OPTIONS

The terms specified below shall be applicable to all Incentive Options.  Except as modified by the provisions of this Section II, all the provisions of Articles One, Two and Five shall be applicable to Incentive Options.  Options that are specifically designated as Non-Statutory Options when issued pursuant to the Plan shall not be subject to the terms of this Section II.

A.                        Eligibility.  Incentive Options may only be granted to Employees.

A-6

B.                          Dollar Limitation.  The aggregate Fair Market Value of the shares of Common Stock (determined as of the respective date or dates of grant) for which one or more options granted to any Employee pursuant to the Plan (or any other option plan of the Corporation or any Parent or Subsidiary) may for the first time become exercisable as Incentive Options during any one calendar year shall not exceed $100,000.  To the extent that an Optionee’s options exceed that limit, they will be treated as Non-Statutory Options (but all of the other provisions of the option shall remain applicable), with the first options that were awarded to the Optionee to be treated as Incentive Options.

C.                          10% Stockholder.  If any Employee to whom an Incentive Option is granted is a 10% Stockholder, then the exercise price per share shall not be less than 110% of the Fair Market Value per share of Common Stock on the date the option is granted, and the Expiration Date shall not be more than five years from the date the option was granted.

III.                                 CORPORATE TRANSACTIONS

A.                        In the event a Change in Control occurs, the shares of Common Stock at the time subject to each outstanding option granted pursuant to this Discretionary Option Grant Program shall automatically vest in full so that each such option shall, immediately prior to the effective date of the Change in Control, become exercisable for all the shares of Common Stock at the time subject to such option and may be exercised for any or all of those shares as fully vested shares of Common Stock.  However, an outstanding option shall not become vested on such an accelerated basis if and to the extent: (1) such option is to be assumed by the successor corporation (or parent thereof) or is otherwise to continue in full force pursuant to the terms of transaction or (2) such option is to be replaced with a cash incentive program of the successor corporation which preserves the spread existing at the time of the Change in Control on any shares for which the option is not otherwise at that time exercisable and provides for subsequent payout of that spread no later than the time the Optionee would vest in those option shares or (3) the acceleration of such option is subject to other limitations imposed by the Plan Administrator at the time of the option grant.

B.                          All outstanding repurchase rights under the Discretionary Option Grant Program shall automatically terminate, and the shares of Common Stock subject to those terminated rights shall immediately vest in full, immediately prior to the occurrence of a Change in Control, except to the extent: (1) those repurchase rights are to be assigned to the successor corporation (or parent thereof) or are otherwise to continue in full force pursuant to the terms of the transaction or (2) such accelerated vesting is precluded by other limitations imposed by the Plan Administrator at the time the repurchase right is issued.

C.                          Immediately following the consummation of the transactions contemplated by the Change in Control documentation, all outstanding options granted pursuant to the Discretionary Option Grant Program shall terminate and cease to be outstanding, except to the extent assumed by the successor corporation (or parent thereof) or otherwise continued in full force and effect pursuant to the terms of the transaction.

D.                         Each option granted pursuant to the Discretionary Option Grant Program which is assumed or otherwise continued in effect in connection with a Change in Control shall

A-7

be appropriately adjusted, immediately after such Change in Control, to apply to the number and class of securities which would have been issuable to the Optionee in consummation of such Change in Control had the option been exercised immediately prior to such Change in Control.  Appropriate adjustments to reflect such Change in Control shall also be made to (1) the exercise price payable per share under each outstanding option, provided the aggregate exercise price payable for such securities shall remain the same, (2) the maximum number and/or class of securities available for issuance over the remaining term of the Plan and (3) the maximum number and/or class of securities for which any one person may be granted options and direct stock issuances pursuant to the Plan per calendar year.  To the extent the holders of Common Stock receive cash consideration for their Common Stock in consummation of the Change in Control, the successor corporation may, in connection with the assumption of the outstanding options granted pursuant to the Discretionary Option Grant Program, substitute one or more shares of its own common stock with a fair market value equivalent to the cash consideration paid per share of Common Stock in such transaction.

E.                           Among its discretionary powers, the Plan Administrator shall have the ability to structure an option (either at the time the option is granted or at any time while the option remains outstanding) so that the option shall become immediately exercisable and some or all of the shares subject to that option shall automatically become vested (and some or all of the repurchase rights of the Corporation with respect to the unvested shares subject to that option shall immediately terminate) upon the occurrence of a Change in Control, the consummation of a Proxy Contest or any other specified event or the Optionee’s Involuntary Termination within a designated period of time following any of these events.  In addition, the Plan Administrator may provide that one or more of the Corporation’s repurchase rights with respect to some or all of the shares held by the Optionee at the time of such a Change in Control, Proxy Contest, or any other specified event or the Optionee’s Involuntary Termination within a designated period of time following such an event shall immediately terminate and all of the shares shall become vested.

F.                           The portion of any Incentive Option accelerated in connection with a Change in Control or Proxy Contest shall remain exercisable as an Incentive Option only to the extent the $100,000 limitation described in Section II.B. above is not exceeded.  To the extent such dollar limitation is exceeded, the accelerated portion of such option shall be exercisable as a Non-Statutory Option under the federal tax laws.

STOCK ISSUANCE PROGRAM

I.                                         STOCK ISSUANCE TERMS

Shares of Common Stock may be issued pursuant to the Stock Issuance Program through direct and immediate issuances without any intervening option grants.  Each such stock issuance shall be evidenced by a Stock Issuance Agreement that complies with the terms specified below.  Shares of Common Stock may also be issued pursuant to the Stock Issuance Program pursuant to awards that entitle the recipients to receive those shares upon the attainment of designated performance goals or the satisfaction of specified Service requirements.

A-8

A.                    Purchase Price.

1.              The purchase price per share shall be fixed by the Plan Administrator, but shall not be less than 100% of the Fair Market Value per share of Common Stock on the date of grant.

2.              Subject to the provisions of Section I of Article Five, shares of Common Stock may be issued pursuant to the Stock Issuance Program for any of the following items of consideration which the Plan Administrator may deem appropriate in each individual instance:

(i)                                     cash or check made payable to the Corporation, or

(ii)                                  past services rendered to the Corporation (or any Parent or Subsidiary).

B.                          Vesting Provisions.

1.              Shares of Common Stock issued pursuant to the Stock Issuance Program may, in the discretion of the Plan Administrator, be fully and immediately vested upon issuance or may vest in one or more installments over the Participant’s period of Service or upon attainment of specified performance objectives.  The elements of the vesting schedule applicable to any unvested shares of Common Stock issued pursuant to the Stock Issuance Program shall be determined by the Plan Administrator and incorporated into the Stock Issuance Agreement.  Shares of Common Stock may also be issued pursuant to the Stock Issuance Program pursuant to awards that entitle the recipients to receive those shares upon the attainment of designated performance goals or the satisfaction of specified Service requirements.

2.              Any new, substituted or additional securities or other property (including money paid other than as a regular cash dividend) which the Participant may have the right to receive with respect to the Participant’s unvested shares of Common Stock by reason of any stock dividend, stock split, recapitalization, combination of shares, exchange of shares or other change affecting the outstanding Common Stock as a class without the Corporation’s receipt of consideration shall be issued subject to such escrow arrangements as the Plan Administrator shall deem appropriate and shall be vested to the same extent the Participant’s shares of Common Stock are vested.

3.              The Participant shall have full stockholder rights with respect to any shares of Common Stock issued to the Participant pursuant to the Stock Issuance Program, whether or not the Participant’s interest in those shares is vested.  Accordingly, the Participant shall have the right to vote such shares and to receive any regular cash dividends paid on such shares.  Cash dividends constitute taxable compensation to the Participant are deductible by the Corporation (unless the Participant has made an election under Section 83(b) of the Code).

4.               Should the Participant cease to remain in Service while one or more shares of Common Stock issued pursuant to the Stock Issuance Program are unvested or should the performance objectives not be attained with respect to one or more such unvested shares of Common Stock, then those shares shall be immediately surrendered to the

A-9

Corporation for cancellation, and the Participant shall have no further stockholder rights with respect to those shares.  To the extent the surrendered shares were previously issued to the Participant for consideration paid in cash or cash equivalent (including the Participant’s purchase-money indebtedness), the Corporation shall repay to the Participant the cash consideration paid for the surrendered shares without interest and/or shall cancel the unpaid principal balance of any outstanding purchase-money note of the Participant attributable to the surrendered shares.

5.              The Plan Administrator may in its discretion waive the surrender and cancellation of one or more unvested shares of Common Stock that would otherwise occur upon the cessation of the Participant’s Service or the non-attainment of the performance objectives applicable to those shares.  Such waiver shall result in the immediate vesting of the Participant’s interest in the shares of Common Stock as to which the waiver applies.  Such waiver may be effected at any time, whether before or after the Participant’s cessation of Service or attainment of the applicable performance objectives.

6.              Outstanding share right awards granted pursuant to the Stock Issuance Program shall automatically terminate, and no shares of Common Stock shall actually be issued in satisfaction of those awards, if the performance goals or Service requirements established for such awards are not attained or satisfied.  The Plan Administrator, however, shall have the discretionary authority to issue shares of Common Stock under one or more outstanding share right awards as to which the designated performance goals or Service requirements have not been attained or satisfied.

II.                                     CORPORATE TRANSACTIONS

A.                        All of the Corporation’s outstanding repurchase rights under the Stock Issuance Program shall terminate automatically, and all the shares of Common Stock subject to those terminated rights shall immediately vest in full, immediately prior to the occurrence of a Change in Control, except to the extent (1) those repurchase rights are to be assigned to the successor corporation (or parent thereof) or are otherwise to continue in full force and effect pursuant to the terms of the transaction or (2) such accelerated vesting is precluded by other limitations imposed in the Stock Issuance Agreement.

B.             The Plan Administrator shall have the discretionary authority to structure one or more of the Corporation’s repurchase rights under the Stock Issuance Program so that those rights shall automatically terminate in whole or in part, and some or all of the shares of Common Stock subject to those terminated rights shall immediately vest, upon the occurrence of a Change in Control, the consummation of a Proxy Contest or any other event, or the Participant’s Involuntary Termination within a designated period of time following any of these events.
