2003 STOCK INCENTIVE PLAN

1. Purpose. The purpose of the iDEFENSE, Inc. 2003 Stock Incentive Plan (the “Plan”) is to further the long term stability and financial success of iDEFENSE, Inc., a Delaware Corporation (the “Company”) by retaining and attracting key employees, non-employee directors and consultants of the Company and its affiliates, through the use of stock incentives. It is believed that ownership of Company Stock will stimulate the efforts of those employees, directors and consultants of the Company upon whose efforts, interest and judgment the Company is and will be largely dependent for success. It is also believed that Incentive Awards granted to employees and directors under this Plan will strengthen their desire to remain with the Company and will further identify their interests with the interests of the Company’s shareholders.

4

shares to be allocated to each Employee as part of each Incentive Award.

6.Restricted Stock Awards.

(a) The Committee may make grants of Restricted Stock to Participants. Whenever the Committee deems it appropriate to grant Restricted Stock, written or electronic notice shall be given to the Participant stating the number of shares of Restricted Stock granted and the terms and conditions to which the Restricted Stock is subject informing him or her that one condition of the grant of Restricted Stock is the execution of a restricted stock purchase agreement materially in the form of the stock purchase agreement exhibited to this Plan (the “Restricted Stock Purchase Agreement”). This notice, when accepted in writing by the Participant shall, subject to the satisfaction of any conditions (including, without limitation the due execution by the Participant of a Restricted Stock Purchase Agreement), become an award agreement between the Company and the Participant and certificates representing the shares shall be issued and delivered to the Participant. Restricted Stock may be awarded by the Committee in its discretion without receipt of consideration from Participants.

(b) No shares of Restricted Stock may be sold, assigned, transferred, pledged, hypothecated, or otherwise encumbered or disposed of until the restrictions on such shares as set forth in the Participant’s award agreement and Restricted Stock Purchase Agreement have lapsed or been removed pursuant to paragraph (d) or (e) below.

(c) Upon the acceptance by a Participant of an award of Restricted Stock, such Participant shall, subject to the restrictions set forth in paragraph (b) above, have all the rights of a shareholder with respect to such shares of Restricted Stock, including, but not limited to, the right to vote such shares of Restricted Stock and the right to receive all dividends and other, distributions paid thereon. Certificates representing Restricted Stock shall bear a legend referring to the restrictions set forth in the Plan and the Participant’s award agreement and the Restricted Stock Purchase Agreement.

(d) The Committee shall establish as to each award of Restricted Stock the terms and conditions upon which the restrictions set forth in paragraph (b) above, other than those contained in the Restricted Stock Purchase Agreement, shall lapse. Such terms and conditions may include, without limitation, the lapsing of such restrictions, other than those set forth in the Restricted Stock Purchase Agreement (which shall only lapse in accordance with the terms thereof), as a result of the Disability, death or retirement of the Participant or the occurrence of a Change of Control.

5

(e) Notwithstanding the provisions of paragraph (b) above, the Committee may at any time, in its sole discretion, accelerate the time at which the restrictions, other than those set out in the Restricted Stock Purchase Agreement, will lapse.

(f) Each Employee shall agree at the time his or her Restricted Stock is granted, and as a condition thereof, to pay to the Company, or make arrangements satisfactory to the Company regarding the payment to the Company of, Applicable Withholding Taxes. Until such amount has been paid or arrangements satisfactory to the Company have been made, no stock certificate free of a legend reflecting the restrictions set forth in paragraph (b) above shall be issued to such Participant. The Company may require the Participant to execute a shareholder agreement or any such other form of agreement as it may deem appropriate as a condition to permitting restrictions on Restricted Stock to lapse.

7.Stock Options.

(a) Whenever the Committee deems it appropriate to grant Options, written or electronic notice shall be given to the eligible person stating the number of shares for which Options are granted, the Option price per share, whether the Options are Incentive Stock Options or Nonstatutory Stock Options and the conditions to which the grant and exercise of the Options are subject. This notice, when duly accepted in writing by the Participant, shall become a stock option agreement between the Company and the Participant.

(b) The exercise price of shares of Company Stock covered by an Incentive Stock Option shall be not less than 100% of the Fair Market Value of such shares on the Date of Grant. The exercise price of shares of Company Stock covered by a Nonstatutory Stock Option shall be not less than 85% of the Fair Market Value of such shares on the Date of Grant. If the Participant to whom an Option is granted is a 10% Shareholder and the Option is an Incentive Stock Option, the exercise price of the Incentive Stock Option shall be not less than 110% of the Fair Market Value of the Company Stock on the Date of Grant.

(c) Options may be exercised in whole or in part at such times as may be specified by the Committee in the Participant’s stock option agreement; provided that the exercise provisions for Incentive Stock Options shall in all events not be more liberal than the following provisions:

(i) No Incentive Stock Option may be exercised after ten years (or, in the case of an Incentive Stock Option granted to a 10% Shareholder, five years) from the Date of Grant.

(ii) An Incentive Stock Option by its terms, shall be exercisable in any calendar year only to the extent that the aggregate Fair Market Value (determined at the Date of Grant) of the Company Stock with respect to which incentive stock options are exercisable for the first time during the calendar year does not exceed $100,000 (the “Limitation Amount”). Incentive Stock Options granted under the Plan and similar incentive options granted under all other plans of the Company and any parent or Subsidiary of the Company shall be aggregated for purposes of determining whether the Limitation Amount has been exceeded. The Committee may impose such conditions as it deems appropriate on an Incentive Stock Option

6

to ensure that the foregoing requirement is met. If Incentive Stock Options that first become exercisable in a calendar year exceed the Limitation Amount, the excess Options will be treated as Nonstatutory Stock Options to the extent permitted by law.

(iii) An Incentive Stock Option shall be subject to such other conditions on exercise as may be imposed under the Code.

(d) The Committee may, in its discretion, grant Options that by their terms become fully exercisable upon a Change of Control, notwithstanding other conditions on exercisability in the stock option agreement.

8.Method of Exercise of Options.

(a) Options may be exercised by the Participant by giving written or electronic notice of the exercise to the Company, stating the number of shares the Participant has elected to purchase under the Option. In the case of the purchase of shares under an Option, such notice shall be effective only if accompanied by the exercise price in full in cash.

(b) The Participant shall execute an agreement in materially the same form as the Restricted Stock Purchase Agreement and the Company may require the Participant to execute any additional shareholder agreement or any such other form of agreement as it may deem appropriate as a condition to the transfer or issue of Company Stock to the Participant upon exercise of an Option. The Company shall place on any certificate representing Company Stock issued upon the exercise of an Option any legend deemed desirable by the Company’s counsel to comply with federal or state securities laws and the terms of the Restricted Stock Purchase Agreement, and the Company may require a customary written indication of the Participant’s investment intent. Until the Participant has made any required payment, including payment of any Applicable Withholding Taxes, and has had issued a certificate for the shares of Company Stock acquired, the Participant shall possess no shareholder rights with respect to the shares.

(c) Each Participant shall agree as a condition of the exercise of an Option to pay to the Company Applicable Withholding Taxes, or make arrangements satisfactory to the Company regarding the payment to the Company of such amounts. Until Applicable Withholding Taxes have been paid or arrangements satisfactory to the Company have been made, no stock certificate shall be issued upon the exercise of an Option.

(d) If the Company Stock is Publicly Traded, as an alternative to making a cash payment to the Company to satisfy Applicable Withholding Taxes, if the Option so provides, or the Committee by separate action so provides, a Participant may, subject to the provisions set forth below, elect to have the Company retain that number of shares of Company Stock that would satisfy all or a specified portion of the Applicable Withholding Taxes. The Committee shall have sole discretion to approve or disapprove any such election.

(e) Notwithstanding anything herein to the contrary, if the Company Stock is Publicly Traded, Options shall always be granted and exercised in such a manner as to conform to the provisions of Rule 16b-3.

7

9.Nontransferability of Options. Options and Restricted Stock (except and only to the extent otherwise set forth in the applicable Restricted Stock Purchase Agreement) shall not be transferable except by will or the laws of descent and distribution, and shall be exercisable during the Participant’s lifetime only by the Participant.

10.Effective Date of the Plan. This Plan shall be effective on August 1, 2003 and shall be submitted to the shareholders of the Company for approval. Until the requirements of any applicable federal or state securities laws have been met, no Option shall be exercisable, and no Restricted Stock shall be granted.

11.Termination, Modification, Change.If not sooner terminated by the Committee, this Plan shall terminate at the close of the business day that is the day immediately preceding the ten-year anniversary of the effective date (as provided in Section 10). No Incentive Awards shall be made under the Plan after its termination. The Committee may terminate the Plan or may amend the Plan in such respects as it shall deem advisable; provided, that, no change shall be made that increases the total number of shares of Company Stock reserved for issuance pursuant to Incentive Awards granted under the Plan (except pursuant to Section 12), expands the class of persons eligible to receive Incentive Awards, or materially increases the benefits accruing to Participants under the Plan, unless such change is authorized by the shareholders of the Company. Notwithstanding the foregoing, the Committee may amend the Plan and unilaterally amend Incentive Awards as it deems appropriate to ensure compliance with applicable federal or state securities laws or regulations thereunder, or any applicable Nasdaq or securities exchange listing requirement, and to cause Incentive Stock Options to meet the requirements of the Code and regulations thereunder, or to cause Incentive Awards to meet conditions imposed under Section 17 of the Plan. Except as provided in the preceding sentence, a termination or amendment of the Plan shall not, without the consent of the Participant, detrimentally affect a Participant’s rights under an Incentive Award previously granted to the Participant.

12.Change in Capital Structure.

(a) In the event of a stock dividend, stock split or combination of shares, recapitalization or merger in which the Company is the surviving corporation or other change in the Company’s capital stock (including, but not limited to, the creation or issuance to shareholders generally of rights, options or warrants for the purchase of common stock or preferred stock of the Company), the number and kind of shares of stock or securities of the Company to be subject to the Plan and to Incentive Awards then outstanding or to be granted thereunder, the maximum number of shares or securities which may be delivered under the Plan pursuant to Section 4, and the exercise price, terms of Incentive Awards and other relevant provisions shall be appropriately adjusted by the Committee, whose determination shall be binding on all persons. If the adjustment would produce fractional shares with respect to any unexercised Option, the Committee may adjust appropriately the number of shares covered by the Option so as to eliminate the fractional shares.

(b) Upon a Deemed Liquidation (if and to the extent defined in the Company’s restated certificate of incorporation) the Board may take such actions with respect to outstanding Incentive Awards as the Board deems appropriate, including, without limitation, canceling the outstanding portion of any Option and paying or delivering, or causing to be paid or delivered, to the Participant an amount in cash or

8

securities having a value (as determined by the Board acting in good faith) equal to the product of (A) the number of shares of Company Stock that, as of the date of the consummation of such Liquidation Event, the Participant had become entitled to purchase pursuant to the Option (and had not purchased) multiplied by (B) the amount, if any, by which (1) the formula or fixed price per share paid to the holders of shares of Company Stock pursuant to such Liquidation Event exceeds (2) the exercise price applicable to such Option.

(c) Notwithstanding anything in the Plan to the contrary, the Committee may take the foregoing actions without the consent of any Participant, and the Committee’s determination shall be conclusive and binding on all persons for all purposes.

13.Administration of the Plan. The Plan shall be administered by the Committee. The Committee shall consist of not less than two (2) members of the Board, who shall be appointed by the Board, unless at any time the Board consists of less than two (2) members, in which case the sole member shall serve as the Committee. Subject to paragraph (d) below, if the Company Stock is Publicly Traded, the Committee shall be the Compensation Committee of the Board unless the Board shall appoint another committee to administer the plan. The Committee shall have general authority to impose any limitations or condition upon an Incentive Award the Board deems appropriate to achieve the objectives of the Incentive Award and the Plan and, without limitation and in addition to powers set forth elsewhere in the Plan, shall have the following specific authority:

(a) The Committee shall have the power and complete discretion to determine (i) which eligible persons shall receive Incentive Awards and the nature of each Incentive Award, (ii) subject to the aggregate number of shares of Company Stock reserved for issuance pursuant to the Plan, the number of shares of Company Stock to be covered by each Incentive Award, (iii) whether Options shall be Incentive Stock Options or Nonstatutory Stock Options, (iv) the Fair Market Value of Company Stock, (vi) the time or times when an Incentive Award shall be granted, (vii) whether an Incentive Award shall become vested over a period of time and when it shall be fully vested, (viii) when Options may be exercised, (ix) whether a Disability exists, (x) the manner in which payment will be made upon the exercise of Options, (xi) conditions, in addition to those contained in the Restricted Stock Purchase Agreement, relating to the length of time before disposition of Company Stock received upon the exercise of Options is permitted, (xii) whether to approve a Participant’s election to have the Company withhold from the shares to be issued upon the exercise of a Nonstatutory Stock Option the number of shares necessary to satisfy Applicable Withholding Taxes, (xiii) notice provisions relating to the sale of Company Stock acquired under the Plan, (xiv) when Incentive Awards may be forfeited or expire, and (xv) any additional requirements relating to Incentive Awards that the Committee deems appropriate. The Committee shall have the power to amend the terms of previously granted Incentive Awards so long as the terms as amended are consistent with the terms of the Plan and provided that the consent of the Participant is obtained with respect to any amendment that would be detrimental to him or her, except that such consent will not be required if such amendment is for the purpose of complying with Rule 16b-3 or any requirement of the Code applicable to the Incentive Award.

(b) The Committee may adopt rules and regulations for carrying out the Plan. The interpretation and construction of any provision of the Plan by the Committee shall

9

be final and conclusive. The Committee may consult with counsel, who may be counsel to the Company, and shall not incur any liability for any action taken in good faith in reliance upon the advice of counsel.

(c) A majority of members of the committee shall constitute a quorum, and all action of the Committee shall be taken by a majority of the members present. Any action may be taken by a written instrument signed by all of the members, and any action so taken shall be fully effective as if it had been taken at a meeting.

(d) The Board from time to time may appoint members previously appointed and may fill vacancies, however caused, in the Committee. If a committee of the Board is appointed to serve as the Committee, such Committee shall have, in connection with the administration of the Plan, the powers possessed by the Board, including the power to delegate to a subcommittee any of the administrative powers the Committee is authorized to exercise, subject, however to such resolutions, not inconsistent with the provisions of the Plan, as may be adopted from time to time by the Board.

(e) With respect to Non-Employee Directors, the Board shall be authorized to make grants of Restricted Stock and Nonstatutory Stock Options in its discretion, provided such grants are made in compliance with other provisions of the Plan. In such case, the Board shall hold the same general and specific authority granted to the Committee under this Section 13 and other provisions of the Plan.

14.Notice. All notices and other communications required or permitted to be given in writing under this Plan shall be deemed to have been duly given if delivered personally or mailed first class, postage prepaid, as follows (a) if to the Company—at its principal business address to the attention of the Chief Financial Officer; (b) if to any Participant at the last address of the Participant known to the sender at the time the notice or other communication is sent.

15.Shareholder Rights. No Participant shall be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares of Company Stock subject to an Incentive Award unless and until such Participation has satisfied all requirements under the terms of the Incentive Award.

16.No Employment or other Service Rights. Nothing in the Plan or any instrument executed or Incentive Award granted under the Plan shall confer upon any Participant any right to continue to serve the Company (or a Parent or Subsidiary of the Company) in the capacity in effect at the time the Incentive Award was granted or shall affect the right of the Company (or a Parent or Subsidiary of the Company) to terminate (i) the employment of an Employee with or without notice and with or without cause, (ii) the service of a Consultant pursuant to the terms of such Consultant’s agreement with the Company (or a Parent or Subsidiary of the Company), or (iii) the service of a Non-Employee Director pursuant to the bylaws of the Company (or a Parent or Subsidiary of the Company), and any applicable provisions of the corporate law of the state in which the Company (or a Parent or Subsidiary of the Company) is incorporated, as the case may be.

17.Options Granted to Non-Exempt Employees. Any Option granted to an Employee who is a nonexempt Employee for purposes of the Fair Labor Standards Act of 1938 (the “FLSA”) shall not be exercisable by the Employee for a period of at least six months after the Date of Grant, to the extent required under the FLSA for such Option to be excluded from the Employee’s “regular rate” (as defined under the FLSA). The Committee may impose such other

10

conditions or limitations on Options granted to nonexempt Employees as it may deem appropriate to qualify such Options for exemption from such Employees’ regular rate under the FLSA.

Interpretation. The terms of the Plan shall be governed by the laws of the Commonwealth of Virginia, without regard to the conflict of law provisions of any jurisdiction. The terms of this Plan are subject to all present and future regulations and rulings of the Secretary of the Treasury or his delegate relating to the qualification of Incentive Stock Options under the Code. If any provision of the Plan conflicts with any such regulation or ruling, then that provision of the Plan shall be void and of no effect.

IN WITNESS WHEREOF, this instrument is effective as of the 1st day of August, 2003.
