Executive Officers

Dennis
A. Bugbee, 59, is Vice President of Finance, Chief Financial Officer, and Secretary. Mr.
Bugbee joined the Company in 1990 as the Division Controller for the Knowledge Systems
Division in Palo Alto, California. He was promoted to Director of Finance March 1, 1993

Space and Defense Sector. He has over 30 years experience in finance and accounting. In
January of 2006, Mr. Bugbee was treated for a serious illness. He has been involved
regularly with this report; however, the Company is currently recruiting for a new
temporary CFO.

The
Board of Directors has determined that none of its Audit Committee members qualifies as an
audit committee financial expert as defined under Item 401 of Regulation S-B of the
Securities Exchange Act of 1934. The Board of Directors expects to recruit a qualified
audit committee financial expert in 2006.

The
Company has adopted a Code of Ethics that applies to the Companys principal
executive officer, principal financial officer, controller, other officers and managers.
The Companys will provide a copy of the Companys Code of Ethics free of charge
to the requesting party.

Section 16(a) Beneficial
Ownership Reporting Compliance

Section
16 of the Securities Exchange Act of 1934, as amended, requires our executive officers (as
defined under Section 16), directors and persons who beneficially own greater than 10% of
a registered class of our equity securities to file reports of ownership and changes in
ownership with the SEC. We are required to disclose any failure of these executive
officers, directors and 10% stockholders to file these reports by the required deadlines.
Based solely on our review of the copies of these reports received by us or written
representations furnished to us, we believe that all filing requirements were met for the
fiscal year, except for Form 4 reporting the grants of stock options under the employee stock
option plan of 20,000 shares each to Messrs Bugbee and O'Mahoney and the Directors
Option Plan of 3,000 shares each to Messrs. Druffel, and Roth, which were not
timely filed as the result of a clerical error.

Item 10. Executive
Compensation

The
following table sets forth the compensation paid to the Chief Executive Officer and the
two most highly compensated executive officers of the Company whose annual salary and
bonus exceeded $100,000 for all services to the Company in the fiscal years ended December
31, 2005, 2004, and 2003.

Directors
Compensation

Directors
Fees. Each non-employee member of the Board of Directors is entitled to receive cash
compensation totaling $10,000 per year, which is paid in quarterly increments of $2,500.
However, each non-employee member may elect to receive stock option grants in lieu of cash
compensation in accordance with the terms of the Directors Option Plan described
below. In 2005, Mr. Druffel, and Mr. Roth elected to receive stock option
grants in lieu of cash compensation for each fiscal quarter. Employee directors are not
compensated for their services as directors of the Company. In addition to their regular
compensation, directors are entitled to be reimbursed for related travel, lodging, and
other expenses in attending board and committee meetings.

Directors
Option Plan. The Company adopted a new Stock Option Plan for Non-Employee Directors that
was approved by the stockholders at the 2002 Annual Meeting. The Directors Plan
provides that each non-employee director shall be granted, on the date such director
becomes a director, an initial option to purchase 3,000 shares of Common Stock, and on the
date of each annual meeting thereafter, each continuing non-employee director shall be
granted an additional option to purchase 3,000 shares of Common Stock. In addition, prior
to any quarter, the Board may elect to grant stock options to each non-employee director
in lieu of the $2,500 quarterly fee for service. The number of shares subject to each
director fee option would be equal to (a) $2,500, divided by (b) the fair market value of
a share of Common Stock on the first business day of the quarter, rounded down to the
nearest whole share. Each stock option granted to a director is fully vested on the date
of grant and has an exercise price per share equal to the fair market value of a share of
Common Stock on the date of grant.

For
information regarding the compensation of executives see Executive
Compensation.

Employment Contracts and Termination of Employment and
Change of Control Arrangements

Neil
Jacobstein, Chairman of the Board, Chief Executive Officer, and President, has an
employment agreement with the Company that provides for a 2006 base salary of $257,000.
Mr. Jacobstein is eligible for a bonus but he waived his potential
bonuses from prior years until the Company turnaround is complete. He was
granted 350,0000 stock options in 2005. Mr. Jacobsteins employment agreement includes
an incentive compensation plan that provides for additional compensation when certain
target objectives are achieved in strategic categories that have been determined and
assessed by the Board of Directors to a maximum of 120% of his annual base salary.
Mr. Jacobstein has a severance package that entitles him to severance benefits equal
to his most recent twelve-month salary and bonus. In the event of a change of control,
defined as any consolidation or merger of the Company in which the Company is not the
continuing or surviving corporation, Mr. Jacobstein will be entitled to the following
severance benefits: (i) full accrued salary and vacation pay, (ii) accrued
incentive compensation awarded or determined to be awarded by the Board of Directors,
(iii) insurance coverage, (iv) retirement benefits, and (v) a lump sum
severance payment equal to two times the total cash compensation (salary and bonus) for
the previous two years.

Item 14. Principal
Accountant Fees and Services

The
following table sets forth the aggregate fees billed to the Company for the fiscal years
ended December 31, 2005 and December 31, 2004 by Burr, Pilger & Mayer LLP and Grant Thornton LLP.

|           | Burr, Pilger & Mayer LLP | Grant Thornton LLP | 
|---------- | ------------------------ | ------------------ | 
|          
|           |                          |                    | 
|           | 2005                     | 2004               | 
|          
|Audit Fees | $158,053                 | -                  | 
|          
|Tax Fees   | $  28,403                | -                  | 
|          

The
Chairman of the Finance and Audit Committee pre-approves all audit and any permissible
non-audit services. There were no non-audit services performed in 2005. Audit fees include
quarterly and annual review of SEC filings and financial results. The preparation of
annual state and federal income tax forms is included in tax fees.

The
Finance and Audit Committee has considered the role of Grant Thornton in providing
consulting, tax services, and other non-audit services to the Company and has concluded
that such services are compatible with Grant Thorntons independence as the
Companys auditors.
