Executive Officers and Directors

Currently, all of our directors hold office until the next annual meeting of our stockholders and until their successors have been duly elected and
qualified. Our officers are elected and serve at the discretion of our board of directors. There are no family relationships among any of our directors and executive officers.

Board Committees

Our board of directors has established three standing committees: an audit
committee; a compensation committee; and a nominating and corporate governance committee.

Audit Committee. The audit committee
oversees, reviews and evaluates our financial statements, accounting and financial reporting processes, internal control functions and the audits of our financial statements. The audit committee is responsible for the appointment, compensation,
retention and oversight of our independent registered public accounting firm. The members of our audit committee are John Bolger, John P. Stenbit and Kenneth R. Thornton. Our board of directors has determined that Mr. Bolger is an audit
committee financial expert, as defined by the rules of the Securities and Exchange Commission.

Compensation Committee. The
compensation committee reviews and makes recommendations to our board of directors concerning the compensation and benefits of our executive officers and directors, administers our stock option and employee benefits plans, and reviews general policy

and recommends board member selection criteria, considers committee member qualification, recommends corporate governance principles to our board of
directors, and provides oversight in the evaluation of our board of directors and each committee. The members of our nominating and corporate governance committee are John Bolger, John P. Stenbit and Kenneth R. Thornton.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934 requires our executive officers, directors and persons who beneficially own more than 10% of our common stock to file initial reports of ownership and reports of changes in ownership
with the SEC. Such persons are required by SEC regulations to furnish us with copies of all Section 16(a) forms filed by such person.

Based solely on our review of such forms furnished to us and written representations from such reporting persons, we believe that all filing requirements applicable to our executive officers, directors and more than 10% stockholders were
met in a timely manner, except that Mr. Hollowich made one late filing with respect to a transaction in May 2005.

Code of Ethics

The Board of Directors has adopted a Code of Ethics that applies to all of our employees, officers and directors. The Code of Ethics is available at
the Companys website at www.cogentsystems.com/investors/.

Option Grants in Last Fiscal Year

We did not grant any stock options to the individuals named in the Summary Compensation Table during the fiscal year ended December 31, 2005.

Aggregated Option Exercises in Last Fiscal Year and Fiscal Year-End Option Values

The following
table sets forth for the individuals named in the Summary Compensation Table their option exercises for the fiscal year ended December 31, 2005, and exercisable and unexercisable options held by them as of December 31, 2005.

The Value of Unexercised In-the-Money Options at December 31, 2005 is calculated based on the difference between the $22.68, the closing
price of our common stock on the Nasdaq National Market on December 30, 2005 (the last trading day of 2005), and the exercise price for the shares underlying the option, multiplied by the number of shares issuable upon exercise of the option.

We have an employment agreement with Paul Kim, entered into on January 5, 2004, under which Mr. Kim is entitled to an annual salary of $208,000,
with a one-time initial bonus of $20,000. On January 5, 2004, Mr. Kim was also granted an option to purchase up to 950,000 shares at an exercise price of $1.00 per share, with 237,500 shares vesting on April 5, 2004, 178,124 shares

We have employment agreements with our
Executive Vice President, Federal and State Systems, James Jasinski and our Executive Vice President, Operations, Michael Hollowich. Each of these agreements provides for a fixed base annual salary that is subject to normal periodic review for
increases by our board or directors, and each of these agreements may be terminated at will by either the employee or us.
