AGREEMENT

     NOW, THEREFORE, in consideration of the mutual promises made herein and for other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the Parties agree to amend the Original Agreement and Amendment No. 1 as follows:

     1.  Definitions . Unless otherwise defined herein, terms used in this Amendment No. 2 shall have the meanings given them in the Original Agreement and Amendment No. 1. Terms not defined by the Parties in the Original Agreement, Amendment No. 1 or in this Amendment No. 2, shall have their plain and ordinary meaning.

     2.  SAIC Relinquishment Of Its Exclusive License To Practice The SAIC Patent Rights Outside The Field Of Use . Effective upon the execution of Amendment No. 2 by the Parties, SAIC hereby relinquishes the exclusive grant back license provided to it by VirnetX pursuant to Section 4.2 of the Original Agreement and Section 2 of Amendment No. 1, as well as any right to obtain such exclusive license in the future. In addition, SAIC confirms that VirnetX has the sole and exclusive right to enforce the SAIC Patent Rights outside the Field of Use for past, present and future infringement, including, without limitation, the right to sue for injunction, damages and otherwise, and the right to collect damages and fees.

     3.  VirnetX Grant Of A Non-Exclusive License To SAIC To Practice The SAIC Patent Rights Outside The Field Of Use . Effective upon the execution of Amendment No. 2 by the Parties, in consideration of the additional exclusive rights obtained by VirnetX from SAIC to practice and license the SAIC Patent Rights outside the Field of Use, VirnetX hereby grants SAIC a nonexclusive, royalty free, fully paid, perpetual, worldwide, irrevocable, sublicensable and transferable right and license under the SAIC Patent Rights outside the Field of Use permitting SAIC and its assignees to make, have made, import, use, offer for sale, and sell products and services covered by, and to make improvements to, the SAIC Patent Rights outside the Field of Use.

     4.  Further Consideration For SAIC’s Transfer Of License Rights Outside The Field Of Use . In further consideration of the additional rights obtained by VirnetX from SAIC to practice and license the SAIC Patent Rights outside the Field of Use, subject to Section 6 below, Section 7.1 of the Original Agreement is hereby amended and restated as follows:

VirnetX shall pay SAIC royalties in the amount of (i) fifteen percent (15%) of all non-license Revenues (as defined in the Original Agreement, but as used throughout this Amendment No. 2, such term shall expressly not include any M&A Entities Recovery, Other Entities Recovery or Acquisition Proceeds (each as defined in Amendment No. 1)) generated by VirnetX in practicing the SAIC Patent Rights in the Field of Use, (ii) fifteen percent (15%) of all license Revenues received by VirnetX pursuant to a license that VirnetX grants in the Field of Use, (iii) fifteen percent (15%) of all non-license Revenues generated by VirnetX in practicing the SAIC Patent Rights outside the Field of Use, and (iv) fifty percent (50%) of all license Revenues received by VirnetX pursuant to a license that VirnetX grants outside the Field of Use. For clarity, in the case of a license that grants rights both inside and outside the Field of Use, VirnetX shall make a good faith apportionment of the license Revenues between payments received for activities within the Field of Use and activities outside the Field of Use and pay the applicable royalty rate on such apportioned Revenues. In addition, in the case of bundled fees received by VirnetX allocable to both non-license Revenues generated by VirnetX in practicing the SAIC Patent Rights and license Revenues received by VirnetX pursuant to a license that VirnetX grants, VirnetX shall make a good faith apportionment of the non-license and license Revenues and pay the applicable royalty with respect to such apportioned Revenues. Notwithstanding the foregoing, VirnetX shall not be obligated to pay any additional amounts pursuant to clauses (i) or (ii) above once the aggregate payments by VirnetX to SAIC are equal to the Maximum Amount (as defined in the Original Agreement); provided that royalty payments due SAIC pursuant to clauses (iii) and (iv) above shall not be included for purposes of determining whether the Minimum Royalty of Section 7.2 of the Original Agreement or whether the Maximum Amount of Section 7.3 of the Original Agreement have been satisfied, and shall not be subject to any minimum or maximum payments, but shall be subject to the payment, reporting and audit requirements of Sections 7.4, 7.5 and 7.6 of the Original Agreement.

     5.  Enforcement Of The SAIC Patent Rights . Notwithstanding anything else in the Original Agreement or Amendment No. 1 to the contrary, from and after the Second Amendment Effective Date, VirnetX shall have the sole right to enforce the SAIC Patent Rights both inside and outside the Field of Use. VirnetX shall take commercially reasonable steps to enforce the SAIC Patent Rights and to protect SAIC’s interest in receiving the bargained-for consideration. VirnetX shall have no obligation to practice the SAIC Patent Rights outside the Field of Use or to seek licensees of the SAIC Patent Rights outside the Field of Use, but VirnetX shall be obligated to use commercially reasonable efforts to prevent infringement of the SAIC Patent Rights outside the Field of Use.

     6.  Allocation Of Certain Proceeds . Notwithstanding anything else herein to the contrary, allocation between VirnetX and SAIC of any M&A Entities Recovery, any Other Entities Recovery and any Acquisition Proceeds shall be governed exclusively by Sections 4, 5, 6 and 7 of Amendment No. 1.

     7.  Arbitration Of Disputes Regarding VirnetX’s Payment Obligations . Any disputes between VirnetX and SAIC regarding any claim, controversy or dispute arising under or related to this Amendment No. 2 shall be addressed and resolved in accordance with Section 13 of the Original Agreement. VirnetX and SAIC agree that Section 13 of the Original Agreement

may be used to seek specific performance of VirnetX’s obligation to use commercially reasonable effort to prevent infringement of the SAIC Patent Rights outside the Field of Use.

     8.  SAIC Review Rights . Notwithstanding anything else in the Original Agreement or Amendment No. 1 to the contrary, VirnetX shall give SAIC reasonable notice in accordance with Section 16.1 of the Original Agreement of any proposed license or assignment of the SAIC Patent Rights (other than to a VirnetX subsidiary as provided in Section 14.3 of the Original Agreement) and any proposed settlement of an action to enforce the SAIC Patent Rights. SAIC may object to the proposed license, assignment or settlement solely on the ground that it unreasonably diminishes the bargained-for consideration agreed by the parties, and SAIC may so object within three business days of receiving notice in accordance with Section 16.1 of the Original Agreement. VirnetX may request SAIC’s consent to any proposed license, assignment or settlement and such consent shall not be unreasonably withheld.

     9.  Modification Of Sections 1.31 And 12 Of The Original Agreement . VirnetX and SAIC agree to the following modifications of the Original Agreement.

	a.		Subsection (iii) of Section 1.31 is deleted.
	b.		Section 12.2.1 is deleted.
	c.		Section 12.2.2 is deleted.
	d.		Section 12.2.5 is deleted.
	e.		Section 12.2.6 is deleted.
	f.		Section 12.2.8 is deleted.
	g.		Section 12.2.9 is deleted.

     10.  SAIC Security Interest In The SAIC Patent Rights . The Security Agreement dated August 12, 2005 between VirnetX and SAIC remains in effect and continues to apply with full force and effect to the SAIC Patent Rights.

     11.  No Other Changes . Except as expressly modified hereby, the Original Agreement and Amendment No. 1 remain in full force and effect.

     12.  Miscellaneous Provisions .

          (a) Entire Agreement . This Amendment No. 2 constitutes the Parties’ entire agreement and understanding with respect to modification of the Original Agreement and Amendment No. 1, supersedes and replaces any and all prior or contemporaneous proposals, agreements, understandings, commitments or representations of any kind, whether written or oral, relating to the Parties’ modification of the Original Agreement and Amendment No. 1.

          (b) Conflicting Provisions . This Amendment No. 2, Amendment No. 1 and the Original Agreement are intended to be read and construed in harmony with each other except as expressly provided. In the event that any provision of the Original Agreement or Amendment No. 1 conflicts with this Amendment No. 2, then this Amendment No. 2 shall be deemed to control, and such conflicting provision, to the extent it conflicts, shall be deemed removed and replaced with the governing provision herein.

          (c) Multiple Copies Or Counterparts Of This Agreement . This Amendment No. 2 may be executed in one or more counterparts, each of which will be deemed an original, but all of which together constitute one and the same instrument and is binding upon the Parties. This Amendment No. 2 shall not be effective until the execution and delivery between the Parties of at least one complete set of the counterparts.

          (d) Governing Law . This Amendment No. 2 shall be governed by and construed in accordance with the laws of the State of California in all respects without giving effect to the principles of conflicts of law thereof.

          (e) Remaining Miscellaneous Provisions and Disputes . The Parties agree that the remaining Miscellaneous Provisions of the Original Agreement shall be applicable to this Amendment No. 2 and are hereby incorporated by reference herein as if restated in their entirety herein with references to the “Agreement” amended to mean this Amendment No. 2. The Parties further agree, to the extent necessary, Section 13 (Disputes) of the Original Agreement shall be applicable to this Amendment No. 2 and is hereby incorporated by reference herein as if restated in its entirety herein with references to the “Agreement” amended to mean this Amendment No. 2.

     IN WITNESS WHEREOF, the Parties have executed this Amendment No. 2 as of the Second Amendment Effective Date.

1. PRELIMINARY STATEMENT

ipCG provides intellectual property strategic planning, development, assessment, implementation, and management services to a variety of business clients. ipCG has developed extensive knowledge and experience in defining opportunities for its clients in building the value of their businesses using intellectual property. Client desires to engage ipCG to present Client with one or more Candidates that may be seeking intellectual property owned by Client, for the purpose of exploiting such intellectual property. ipCG is willing to enter into such an engagement.

In view of the foregoing, ipCG and Client desire to enter into the present Agreement, and in consideration of the mutual promises and covenants contained herein, the parties agree as set forth herein.

2. DEFINITIONS

2.1 “IP Rights” shall mean the legal rights in any copyrights, patents, trademarks, trade secrets, know-how, or other intellectual property.

2.2 “Candidate” shall mean any entity, natural person, or group of entities or natural persons presented to Client by ipCG during the term of this Agreement, that is seeking IP Rights from Client. For the purposes of determining when Success Fee(s) are payable under this Agreement, when a Candidate is other than a natural person, entities owned by, or holding direct or indirect ownership interest in, a Candidate which is a party to the IP Agreement, including parent, subsidiary, and sister entities (e.g., two divisions of a parent corporation) of such Candidate, shall not be considered a Candidate.

2.3 “IP Agreement” shall mean any contract or agreement (including settlements entered into in connection with any litigation, actual or threatened), and amendments to any such contract or agreement between Client (or a Client affiliate) and any Candidate, including, but not limited to, rights to make, have made, use, sell, offer for sale, import or license others to make, have made, use, sell, offer for sale, or import products or use processes in connection with any of the foregoing, that are covered by or use the IP Rights. The rights can include but are not limited to (1) exclusive or non-exclusive patent and/or technology licenses, (2) covenants not to sue, (3) settlement agreements, (4) partial or total assignments of intellectual property in the IP Rights and (5) corporate merger or acquisition where the primary purpose is the acquisition of IP Rights.

2.4 “Success Fee” shall have the meaning ascribed in Section 4.1.

2.5 “Target Technology” shall mean the technical subject matter identified in Attachment A.

2.6 “Additional Services” include, but are not limited to, patent mapping, invention development, strategic inventing, strategic planning, patent scoring, due diligence, market analysis, IP valuation, and litigation support.

3. BROKERAGE SERVICES

3.1 ipCG shall use commercially reasonable efforts to introduce Client to five Candidates mutually agreed upon by ipCG and Client in writing (the “Mutually Agreed Candidates”), which are interested in seeking IP Rights relating to the Target Technology from Client, whether by assignment, license or otherwise.

3.2 Once Client and a Mutually Agreed Candidate have agreed in principle to enter into an IP Agreement, and at Client’s request, ipCG shall use commercially reasonable efforts, to assist Client in negotiating the IP Agreement, including i) assisting Client in developing terms and conditions for the IP Agreement; ii) reviewing and providing feedback relative to drafts of the IP Agreement prepared by Client’s counsel; iii) assisting Client in negotiating deal terms; and iv) assisting Client in closing the IP Agreement. ipCG is not a law firm and shall have no obligation to provide legal services under this Agreement.

3.3 Client agrees that ipCG shall be Client’s exclusive broker for IP Rights relating to the Target Technology with respect to the Mutually Agreed Candidates during the term of this Agreement. Client shall notify ipCG of any inquiries made to Client by Mutually Agreed Candidates, or by Client to Mutually Agreed Candidates, in either case during the term of this Agreement concerning assigning, licensing or otherwise exploiting IP Rights relating to the Target Technology.

3.4 ipCG reserves the right to present any Candidate to parties other than Client.

3.5 Client, at ipCG’s discretion, may engage ipCG under this Agreement to perform one or more Additional Services. Client will provide mutually agreeable compensation to ipCG for such Additional Services, as negotiated by the parties. For clarity, Client and ipCG acknowledge that they are concurrently entering into a separate Engagement Letter for Strategic Intellectual Property Licensing and Training (the “Engagement Letter”), which are Additional Services that are critical to Client’s willingness to enter into this Agreement.

3.6 Client agrees by signing this agreement that it is recognized that ipCG may find that a simple introduction of the Target Technology to a Mutually Agreed Candidate may be enough to obtain results from the Mutually Agreed Candidate and / or the Client also recognizes that ipCG may have to spend significant time to track down a viable opportunity that obtains results, and that in either of these cases, the Success Fee shall be granted to ipCG independent of the effort ipCG makes.

4. ipCG SUCCESS FEE

4.1 If, at any time during the term of this Agreement or prior to the 3rd anniversary of the date of termination of this Agreement, Client enters into an IP Agreement relating to IP Rights with a Mutually Agreed Candidate, then except as otherwise provided in this Agreement, Client will pay ipCG the following success fee (the “Success Fee”):

4.1.1 10% of the royalties, fees and other consideration, including non-cash consideration, paid over the life of the IP Agreement, payable to ipCG within thirty (30) days of receipt of each payment, up to a maximum aggregate amount of $2,000,000 per Mutually Agreed Candidate or $10,000,000 in the aggregate to be paid as Success Fees to ipCG with respect to any and all IP Agreements or otherwise to ipCG by Client hereunder.

4.2 Client agrees that it shall take no action to delay closing of an IP Agreement beyond the three-year period primarily for the purpose of avoiding payment of a Success Fee, nor shall it avoid taking any action primarily for the purpose of delaying closing beyond the three-year period to avoid payment of a Success Fee.

4. 3 ipCG acknowledges and agrees that Client may decide, in its sole discretion, whether or not to enter into an IP Agreement concerning any given IP Rights and there is a possibility that no Success Fee or other compensation will be earned by ipCG under this Agreement.

4.4 Client shall keep accurate records sufficient to permit determination of the payments due hereunder and shall make such records available for examination by a third-party auditor designated by ipCG and reasonably acceptable to Client, following reasonable advance notice and under conditions of confidentiality during regular business hours. Audits may be performed covering no more than the four most recently reported consecutive quarters preceding the audit and may be performed no more than once in any calendar year. ipCG’s failure to inspect shall not constitute a waiver of ipCG’s right to object to the accuracy of payments made under this Agreement. Before beginning any audit, ipCG agrees that the third-party auditors shall be required to sign a confidentiality agreement provided by Client that restricts the auditors from disclosing to any third party any and all records and other information provided by Client. Each party shall be responsible for its own costs and expenses that it incurs in the course of the audit and ipCG shall be responsible for the costs and expenses charged by the third-party auditors.

5. CLIENT DUTIES

5.1 Client will, upon request, promptly provide all information and documentation reasonably deemed necessary or desirable by ipCG in connection with performing its services under this Agreement. Client understands and agrees that ipCG intends to use the information and documentation furnished by Client without making an independent investigation into the accuracy of the information and documentation.

5.2 Client agrees to promptly notify ipCG of any matters affecting ipCG’s ability to provide its services under this Agreement including, but not limited to, loss of any portion of the IP Rights and the existence of potentially interfering rights owned by others.

Such termination shall become automatically effective unless such other party shall have remedied the breach prior to the expiration of the forty-five (45) day cure period.

6.3 Upon any termination of this Agreement, the provisions of Sections 4, 7, 8 and 9 shall survive and continue in full force and effect, except to the extent they expire of their own accord, and except that Section 4 shall not survive in the event Client terminates this Agreement pursuant to Section 6.2.

Before disclosure to any such party, Recipient will have an

agreement in place requiring the party to treat Confidential Information in accordance with the use and disclosure restrictions contained in this Agreement. Recipient may disclose Confidential Information to the extent required by law; provided, however, that Recipient must give the disclosing party prior written notice and make a reasonable effort to obtain a protective order.

9. LIMITATION OF LIABILITY

9.1 NEITHER PARTY SHALL BE LIABLE TO THE OTHER PARTY FOR ANY INCIDENTAL, CONSEQUENTIAL, SPECIAL, INDIRECT OR EXEMPLARY DAMAGES ARISING OUT OF THIS AGREEMENT, INCLUDING LOST PROFITS OR COSTS OF COVER, LOSS OF USE OR BUSINESS INTERRUPTION OR THE LIKE, REGARDLESS OF WHETHER THE PARTY WAS ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
