Our Company
From inception in 1992 until January 2003, VirnetX Holding Corporation (through its predecessor corporation) was engaged in the business of developingCan Find More Information” and licensing software that enabled internet and web-based communications. As of January 31, 2003, we had sold all of our operating assets, and since such time our only source of revenue has been derived from nominal royalties payable to our wholly-owned Japan subsidiary, Network Research Corp. Japan, Ltd. pursuant to the terms of a single license agreement. We acquired VirnetX as a wholly-owned subsidiary on July 5, 2007 and ceased being a shell company (the “Merger”). Additionally, pursuant to the merger with VirnetX, we experienced a change in control, with the former securityholders of VirnetX acquiring control of VirnetX Holding Corporation.
Our wholly-owned subsidiary, VirnetX, was incorporated in the State of Delaware in August 2005. It is a development stage company that was formed to commercialize a patent portfolio for providing solutions for secure real-time communications such as instant messaging, or “IM,” and voice over internet protocol, or “VoIP.” VirnetX has acquired certain patents from Science Applications International Corporation, a systems, solutions and technical services company based in San Diego, California (better known as “SAIC”).
Principal Products and Services
Technology and Solutions Business
Our primary strategy for our technology and solutions business is to commercialize our patented technology in the area of secure real-time communication. We are developing technology for:
• “single-click” and “zero-click” security solutions for real-time communications; and
• “end-to-end” security for VoIP, video conferencing and other types of peer-to-peer collaboration without degradation in quality of service.
In addition, we expect to continue to generate nominal royalties payable to our Japan subsidiary pursuant to the terms of a single license agreement.
Contract Services Business
Our primary strategy for our contract services business is to leverage our research and development group to provide contract research, prototyping, systems integration and technical services to numerous branches of the U.S. Federal government, network service providers and other OEM partners. Our team is staffed with nationally accredited scientists who have experience with research and development projects concerning industry-wide security solutions as well as national security. We intend to provide these contract services to assist the research and development efforts of our corporate and OEM developers“Incorporation by providing outsourced research, deployment and testing services designed to secure and simplify networks.Reference.”
 
We believeare offering to sell, and seeking offers to buy, shares of common stock only in jurisdictions where such offers and sales are permitted.  The distribution of this prospectus supplement, the accompanying base prospectus, any free writing prospectus that the revenue generated by our contract services business will eventually partially offset the costs of our technology and solutions business and will provide us with the opportunity to generate future strategic relationships and licensing opportunities. We also anticipate that future contract services projects will enable us to develop promising new technologies that can be commercialized through our technology and solutions business.
Microsoft Litigation
We believe Microsoft Corporation is infringing certain of our patents. Accordingly, we commenced a lawsuit against Microsoft on February 15, 2007 by filing a complaintmay authorize for use in the United States District Court of the Eastern


1


District of Texas, Tyler Division. Pursuant to the complaint, we allege that Microsoft infringes two of our U.S. patents: U.S. Patent No. 6,502,135 B1, entitled “Agile Network Protocol for Secure Communications with Assured System Availability,” and U.S. Patent No. 6,839,759 B2, entitled “Method for Establishing Secure Communication Link Between Computers of Virtual Private Network Without User Entering Any Cryptographic Information.” On April 5, 2007, we filed an amended complaint specifying certain accused products at issue and alleging infringement of a third, recently issued U.S. patent: U.S. Patent No. 7,188,180 B2, entitled “Method for Establishing Secure Communication Link Between Computers of Virtual Private Network.” We are seeking both damages, in an amount subject to proof at trial, and injunctive relief. Microsoft answered the amended complaint and asserted counterclaims against us on May 4, 2007. Microsoft counterclaimed for declarations that the three patents are not infringed, are invalid and are unenforceable. Microsoft seeks an award of its attorneys’ fees and costs. We filed a reply to Microsoft’s counterclaims on May 24, 2007. Discovery has begun, a Markman hearing on claim construction is scheduled for February 2009,this offering and the trial is scheduled to begin on October 12, 2009. We have served our infringement contentions directed to certain of Microsoft’s operating system and unified messaging and collaboration applications. On March 31, 2008, Microsoft filed a Motion to Dismiss for lack of standing, which was denied by the court pursuant to an order dated June 3, 2008. Also pursuant to that court decision, on June 10, 2008, SAIC joined us in our lawsuit.
Summary Financial Data
The summary financial data set forth below is derived from our financial statements and notes thereto, and should be read in conjunction with, and is qualified in its entirety by reference to, our consolidated financial statements and notes thereto and the information contained under the caption “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” in each case appearing elsewhere in this prospectus.
For accounting purposes, VirnetX Holding Corporation was a publicly-held shell company prior to the merger with VirnetX.

SALES AGREEMENT PROSPECTUS SUPPLEMENT SUMMARY
 
This summary provides a general overview of selected information and does not contain all of the information you should consider before buying our common stock.  Therefore, you should read the entire prospectus supplement, accompanying base prospectus and any free writing prospectus that we have authorized for use in connection with this offering carefully, including the information incorporated by reference, before deciding to invest in our common stock.  Investors should carefully consider the information set forth under “Risk Factors” beginning on page S-6 and incorporated by reference to our most recent annual report on Form 10-K, quarterly reports on Form 10-Q and our other filings with the Commission.
We develop software and technology solutions for securing real-time communications over the Internet. Our patented GABRIEL Connection TechnologyTM combines industry standard encryption protocols with our patented techniques for automated domain name system, or DNS, lookup mechanisms, and enables users to create a secure communication link using secure domain names over wired or wireless (4G/LTE) networks. We are currently beta testing our GABRIEL Connection TechnologyTM as part of our Secure Domain Name Initiative, or (SDNI), on various platforms including PCs, smart phones and tablets. We also intend to establish the exclusive secure domain name registry in the United States and other key markets around the world.
Our portfolio of intellectual property is the foundation of our business model. Our patent portfolio is primarily focused on securing real-time communications over the Internet, as well as related services such as the establishment and maintenance of a secure domain name registry. Our patented methods also have additional applications in the key areas of device operating systems and network security for Cloud services, Mobile-to-Mobile (M2M) communications in areas of Smart City, Connected Car and Connected Home.
We have submitted a declaration with the 3rd Generation Partnership Project, or 3GPP, identifying a group of our patents and patent applications that we believe are or may become essential to certain developing specifications in the 3GPP LTE, SAE project. We have agreed to make available a non-exclusive patent license under fair, reasonable and non-discriminatory terms and conditions, with compensation, or FRAND, to 3GPP members desiring to implement the technical specifications identified by us. We believe that we are positioned to license our essential security patents to 3GPP members as they move into 4G.
We believe that the market opportunity for our software and technology solutions is large and expanding as secure domain names are now an integral part of securing the next generation 4G/LTE Advanced wireless networks and Mobile-to-Mobile (M2M) communications in areas including Smart City, Connected Car and Connected Home. We also believe that all 4G/LTE Advanced mobile devices will require unique secure domain names and become part of a secure domain name registry.
We intend to license our patent portfolio, technology and software, including our secure domain name registry service, to domain infrastructure providers, communication service providers as well as to system integrators. We intend to seek further license of our technology, including our GABRIEL Connection TechnologyTM to enterprise customers, developers and original equipment manufacturers, or OEMs, of chips, servers, smart phones, tablets, e-Readers, laptops, net books and other devices, within the IP-telephony, mobility, fixed-mobile convergence and unified communications markets including 4G/LTE. We have published our royalty rates and guidelines on our website. All forward moving licenses have adhered to these guidelines and have met or exceeded these rates and we will use these rates and guidelines in all future license negotiations.
Our software and technology solutions provide the security platform required by next-generation Internet-based applications such as instant messaging, or IM, voice over Internet protocol, or VoIP, mobile services, streaming video, file transfer, remote desktop and Mobile-to-Mobile (M2M) communications in areas including Smart City, Connected Car and Connected Home. Our technology generates secure connections on a “zero-click” or “single-click” basis, significantly simplifying the deployment of secure real-time communication solutions by eliminating the need for end-users to enter any encryption information.
Our employees include the core development team behind our patent portfolio, technology and software. This team has worked together for over ten years and is the same team that invented and developed this technology while working at Leidos, Inc. Leidos, Inc. is a FORTUNE 500® scientific, engineering and technology applications company that uses its deep domain knowledge to solve problems of vital importance to the nation and the world, in national security, energy and the environment, critical infrastructure and health. The team has continued its research and development work started at Leidos, Inc. and expanded the set of patents we acquired in 2006 from Leidos, Inc. into a larger portfolio with over 112 U.S. and international patents with over 75 pending applications. This portfolio now serves as the foundation of our licensing business and planned service offerings and is expected to generate the majority of our future revenue in license fees and royalties. We intend to continue our research and development efforts to further strengthen and expand our patent portfolio. See Management’s Discussion and Analysis of Financial Condition and Results of Operations–Operations–Research and Development Expenses in our Annual Report on Form 10-K for the fiscal year ending December 31, 2014, filed with the Securities and Exchange Commission on March 2, 2015.
VirnetX, Inc., was incorporated in the State of Delaware in August 2005. In November 2006, VirnetX acquired certain patents from Leidos, Inc. In July 2007, we effected a reverse merger between PASW, Inc. and VirnetX, which became our principal operating subsidiary. As a result of this merger, the former security holders of VirnetX came to own a majority of our outstanding common stock. On October 29, 2007, we changed our name from PASW, Inc. to VirnetX Holding Corporation. Our principal executive offices are located at 308 Dorla Ct., Zephyr Cove, Nevada 89448, and our telephone number is (775) 548-1785.

Risks related to existing and future litigation
We have commenced legal proceedings against Microsoft, and we expect such litigation to be time-consuming and costly, which may adversely affect our financial condition and our ability to operate our business.
On February 15, 2007, we initiated a lawsuit by filing a complaint against Microsoft in the United States District Court for the Eastern District of Texas, Tyler Division, pursuant to which we allege that Microsoft infringes two of our patents regarding the creation of VPNs. We seek damages and injunctive relief. On April 5, 2007, we filed an amended complaint, pursuant to which we allege that Microsoft infringes a third patent. We anticipate that these legal proceedings may continue for several years and may require significant expenditures for legal fees and other expenses. The time and effort of our management to effectively pursue the Microsoft lawsuit may adversely affect our ability to operate our business since time spent on matters related to the lawsuit will take away from the time spent on managing and operating our business. Microsoft has counterclaimed for declarations that the three patents are not infringed, are invalid and are unenforceable. If Microsoft’s counterclaims are successful, they may preclude our ability to commercialize our initial products. Additionally, we anticipate that our legal fees will be material and will negatively impact our financial condition and results of operations and may result in our inability to continue our business.
While we believe Microsoft infringes our patents, we can provide no assurance that we will be successful in our lawsuit.
We believe that Microsoft infringes on three of our patents, but obtaining and collecting a judgment against Microsoft may be difficult or impossible. Patent litigation is inherently risky and the outcome is uncertain. Microsoft is a large, well-financed company with substantially greater resources than us. We believe that Microsoft will devote a substantial amount of resources in an attempt to prove that either their products do not infringe our patents or that our patents are not valid and are unenforceable. At this time, we cannot predict the outcome of this litigation.
We are devoting a substantial amount of our financial and management resources to the Microsoft litigation, and if we are unsuccessful in this lawsuit, our financial condition may be so adversely affected, we may not survive.
Currently, we are devoting substantial time, effort and financial resources to our lawsuit against Microsoft. We are a development stage company with no finished product, and our business strategy depends greatly on obtaining a judgment in our favor from the courts and collecting such judgment before our financial resources are depleted. In the event we are not awarded and do not subsequently obtain monetary and injunctive relief, we may not have enough financial resources to continue our operations.
 
The burdens of being a public company may adversely affect our abilityRisks Relating to pursue the Microsoft litigation.this Offering
 
AsOur management team may invest or spend the proceeds of this offering in ways with which you may not agree or in ways which may not yield a public company,significant return.
Our management will have broad discretion over the use of proceeds from this offering.  We intend to use the net proceeds, if any, from this offering to fund our planned registration program for working capital and general corporate purposes.  Our management must devotewill have considerable discretion in the application of the net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately.  The net proceeds may be used for corporate purposes that do not increase our operating results or enhance the value of our common stock.
You may experience immediate and substantial time, attention and financial resourcesdilution in the net tangible book value per share of the common stock you purchase.
The price per share of our common stock being offered may be higher than the net tangible book value per share of our common stock outstanding prior to comply with U.S. securities laws. This may have a material adverse affect on management’s ability to effectively pursue the Microsoft litigation as well as our other business initiatives. In addition, our disclosure obligations under U.S. securities laws require us to disclose information publicly thatthis offering.  The shares sold in this offering, if any, will be available to Microsoft as well as any other future litigation opponents. We may,sold from time to time be requiredat various prices. After giving effect to disclose information that will have a


4


material adverse affect on our litigation strategies. This information may enable our litigation opponents to develop effective litigation strategies that are contrary to our interests.
We may commence additional legal proceedings against third parties who we believe are infringing on our intellectual property rights, and such legal proceedings may be costly and time-consuming.
We may have intellectual property infringement claims against other parties in addition to our claims against Microsoft. If we decide to commence actions against any additional parties, doing so may be expensive and time-consuming, which may adversely affect our financial condition and results of operations. Moreover, there can be no assurance that we would be successful in these additional legal proceedings. Commencing lawsuits may lead to potential counterclaims which may preclude our ability to develop and commercialize our initial products.
Risks related to our business and our industry
We anticipate incurring operating losses and negative cash flows in the foreseeable future resulting in uncertainty of future profitability and limitations on our operations.
We anticipate that we will incur operating losses and negative cash flows in the foreseeable future, and we will accumulate increasing deficits as we increase our expenditures for:
• our lawsuit against Microsoft;
• infrastructure;
• sales and marketing;
• research and development;
• personnel; and
• general business enhancements.
We need to significantly increase our revenue if we are to attain profitability. In the event that we are unable to achieve profitability or raise sufficient funding to cover our losses, we may not be able to meet our obligations as they come due, raising substantial doubts as to our ability to continue as a going concern.
We will need additional capital to pursue our litigation strategy, conduct our operations and develop our products, and our ability to obtain the necessary funding is uncertain.
We will require significant additional capital from sources including equityand/or debt financings, license arrangements, grants, collaborative research arrangementsand/or other sources in order to develop and commercialize our products and continue operations. If we are not able to raise additional capital when needed, our business will fail.
We are a development stage company with virtually no revenues.
We are a development stage company with a very small amount of revenue and do not expect to generate additional revenues unless and until after our patent portfolio, or part of it, is commercialized. We will need to raise additional capital to fund our operations and our litigation against Microsoft and there can be no assurance that we will be successful in doing so on acceptable terms or at all.
If we fail to meet our obligations to SAIC, we may lose our rights to key technologies on which our business depends.
Our business depends on our rights to and under the patents we obtained from SAIC. Our agreements with SAIC impose various obligations on us, including payment obligations and minimum royalties that we must pay to SAIC. If SAIC believes that we have failed to meet these obligations, SAIC could seek to limit or reacquire the assigned patent rights, which could lead to costly and time-consuming litigation and, potentially, a loss of our rights in these patents. During the period of any such litigation, our ability to carry out the development and


5


commercialization of potential products could be significantly and negatively affected. The loss or restriction of our rights in our patents would result in our inability to continue our business.
Our business model is new and unproven, and therefore we can provide no assurance that we will be successful in pursuing it.
We intend to develop products to provide secure communication for IM and VoIP; however, this is not a defined market. Rather, it represents a new business model, for which there are no assurances that we will succeed in building a profitable business. We expect to depend on our intellectual property licensing fees for the majority of our revenues. Our ability to generate licensing fees is highly dependent on mainstream market adoption of real-time messaging and collaboration solutions based on SIP. There can be no assurance that such adoption will occur. If we are unable to attract significant licensing fees, our operations and financial condition will be adversely affected.
We may or may not be able to capitalize on potential market opportunities related to our licensing strategy or our patent portfolio.
We have engaged ipCapital Group to help develop our licensing strategy and to introduce the Company to five strategic licensees of the Company’s technology. In connection with this engagement, we agreed to grant ipCapital Group 10% of the royalties of each resulting licensing arrangement, up to an aggregate maximum of $2,000,000 per licensee, or $10,000,000 in the aggregate. Also in connection with this engagement, ipCapital Group evaluated the Company’s patent and know-how portfolio, business model and technology and has indicated that the estimated potential commercialization of these items presents the Company with a multi-billion dollar market opportunity. There can be no assurance that we will be able to capitalize on this potential market opportunity. Our inability to generate licensing revenues associated with the potential market opportunity identified by ipCapital Group could result from a number of factors, including, but not limited to:
• our capital resources may be insufficient;
• our management team may not have sufficient bandwidth to successfully capitalize on all of the opportunities identified by ipCapital Group;
• our licensing program may not be adopted by potential licensing partners; and
• the validity of our patents underlying the licensing opportunity is currently being challenged in our litigation against Microsoft.
We will rely on third parties for software and hardware development, manufacturing content and technology services.
We expect to rely on third party developers to provide software and hardware. If we experience problems with any of our third party technology or products, our customers’ satisfaction could be reduced, and our business could be adversely affected. In addition, we expect to rely on third parties to provide content through strategic relationships and other arrangements. If we experience difficulties in maintaining these relationships or developing new relationships on a timely basis and on terms favorable to us, our business and financial condition could be adversely affected.
Malfunctions of third party hosting services could adversely affect their business, which may impede our ability to attract and retain strategic partners and customers.
The products we are developing will be highly dependent on internet traffic and reliability. To the extent the number of users of networks utilizing our future products suddenly increases, the technology platform and hosting services which will be required to accommodate a higher volume of traffic may result in slower response times or service interruptions. System interruptions or increases in response time could result in a loss of potential or existing users and, if sustained or repeated, could reduce the appeal of the networks to users. In addition, users depend on real time communication: outages caused by increased traffic could result in delays and system failures. These types of occurrences could cause users to perceive that our solution does not function properly and could therefore adversely affect our ability to attract and retain licensees, strategic partners and customers.

There has been increased competition in the “real-time” communications industry, as more companies seek to provide products and services similar to our proposed products and services, and because larger and better-financed competitors may affect our ability to operate our business and achieve profitability, our business may fail.
Competition for securing IM and VoIP services is intense. We are aware of similar products and services that will compete directly with our proposed products and services, and some of the companies developing these similar products and services are larger, better-financed companies that may develop products superior to our proposed products, which could create significant competitive advantages for those companies. Our future success depends on our ability to compete effectively with our competitors. As a result, we may have difficulty competing with larger, established competitor companies. Generally, these competitors have:
• substantially greater financial, technical and marketing resources;
• a larger customer base;
• better name recognition; and
• more expansive product offerings.
These competitors are likely to command a larger market share than us, which may enable them to establish a stronger competitive position, in part, through greater marketing opportunities. Further, our competitors may be able to respond more quickly to new or emerging technologies and changes in user preferences and to devote greater resources to developing and operating networks of affinity websites. These competitors may develop products or services that are comparable or superior. If we fail to address competitive developments quickly and effectively, we may not be able to remain a viable entity.
Our business model depends on our ability to successfully develop and operate our networks and deploy new offerings and technology.
If we successfully develop and commercialize products, there can be no assurances that we will not experience reliability problems in the future. Any reliability problems that adversely affect our ability to operate our networks would likely reduce revenues and restrict the growth of our business. Our future success will also depend in part on other factors, including, but not limited to, our ability to:
• find secure hosting;
• enhance our offerings;
• address the needs of our prospective users;
• respond to technological advances and emerging industry standards and practices on a timely and cost-effective basis; and
• develop, enhance, and improve the responsiveness, functionality and features of our infrastructure services and networks.
If we are unable to integrate and capitalize on new technologies and standards effectively, our business could be adversely affected.
Growth of internal operations and business may strain our financial resources.
We intend to significantly expand the scope of our operating and financial systems in order to build our business. Our growth rate may place a significant strain on our financial resources for a number of reasons, including, but not limited to, the following:
• the need for continued development of the financial and information management systems;
• the need to manage relationships with future licensees, resellers, distributors and strategic partners;


7


• the need to hire and retain skilled management, technical and other personnel necessary to support and manage our business; and
• the need to train and manage our employee base.
The addition of new infrastructure services, networks, vertical categories and affinity websites and the attention they demand, on top of the attention demanded by our pending litigation with Microsoft, may also strain our management resources. We cannot give you any assurance that we will adequately address these risks and, if we do not, our ability to successfully expand our business could be adversely affected.
If we do not successfully develop our planned products and services in a cost-effective manner to customer demand in the rapidly evolving market for internet andIP-based communications services, our business may fail.
The market for communications services is characterized by rapidly changing technology, evolving industry standards, changes in customer needs and frequent new service and product introductions. We are currently focused on developing products to provide security solutions for real-time communications. Our future success will depend, in part, on our ability to use new technologies effectively, to continue to develop our technical expertise, to enhance our existing services and to develop new services that meet changing customer needs on a timely and cost-effective basis. We may not be able to adapt quickly enough to changing technology, customer requirements and industry standards. If we fail to use new technologies effectively, to develop our technical expertise and new services, or to enhance existing services on a timely basis, either internally or through arrangements with third parties, our product and service offerings may fail to meet customer needs, which would adversely affect our revenues and prospects for growth.
In addition, if we are unable, for technological, legal, financial or other reasons, to adapt in a timely manner to changing market conditions or customer requirements, we could lose customers, strategic alliances and market share. Sudden changes in user and customer requirements and preferences, the frequent introduction of new products and services embodying new technologies and the emergence of new industry standards and practices could render our existing products, services and systems obsolete. The emerging nature of products and services in the technology and communications industry and their rapid evolution will require that we continually improve the performance, features and reliability of our products and services. Our success will depend, in part, on our ability to:
• design, develop, launchand/or license our planned products, services and technologies that address the increasingly sophisticated and varied needs of our prospective customers; and
• respond to technological advances and emerging industry standards and practices on a cost-effective and timely basis.
The development of our planned products and services and other proprietary technology involves significant technological and business risks and requires substantial expenditures and lead time. We may be unable to use new technologies effectively. Updating our technology internally and licensing new technology from third-parties may also require us to incur significant additional expenditures.
Our business greatly depends on the development and growth of IM and VoIP.
The use of the internet for communications utilizing IM and VoIP is a recent development, and the continued demand and growth of a market for IM and VoIP services and products is uncertain. The internet may ultimately prove not to be a viable commercial marketplace for IM and VoIP services for a number of reasons, including:
• unwillingness of consumers to shift to VoIP;
• refusal to purchase security products;
• perception by the licensees of unsecure communication and data transfer;
• lack of concern for privacy by licensees and users;
• limitations on access and ease of use;


8


• congestion leading to delayed or extended response times;
• inadequate development of internet infrastructure to keep pace with increased levels of use; and
• increased government regulations.
While the use of IM has grown rapidly in personal and professional use, there can be no assurance that users will pay to secure their IM services.
Many services such as Microsoft, Yahoo! and AOL offer IM free of charge. However, security solutions for these services are not free, and users of IM may not want to pay for such security solutions. If users do not want to pay for the security solutions, we will have difficulty marketing and selling our products and technologies.
If the market for VoIP service does not develop as anticipated, our business would be adversely affected.
The success of our products that secure enterprise VoIP service depends on the growth in the number of VoIP users, which in turn depends on wider public acceptance of VoIP telephony. The VoIP communications medium is in its early stages and may not develop a broad audience. Potential new users may view VoIP as unattractive relative to traditional telephone services for a number of reasons, including the need to purchase computer headsets or the perception that the price advantage for VoIP is insufficient to justify the perceived convenience. Potential users may also view more familiar online communication methods, such ase-mail or IM, as sufficient for their communications needs. There is no assurance that VoIP will ever achieve broad public acceptance.
If our products do not gain market acceptance, we may not be able to fund future operations.
A number of factors may affect the market acceptance of our planned products or any other products we develop or acquire, including, among others:
• the price of our products relative to other products that seek to secure real-time communication;
• the perception by users of the effectiveness of our products;
• our ability to fund our sales and marketing efforts; and
• the effectiveness of our sales and marketing efforts.
If our products do not gain market acceptance, we may not be able to fund future operations, including the development of new productsand/or our sales and marketing efforts for our current products, which inability would have a material adverse effect on our business, financial condition and operating results.
If we are not able to adequately protect our proprietary rights, our operations would be negatively impacted.
Our ability to compete largely depends on the superiority, uniqueness and value of our technology and intellectual property. To protect our proprietary rights, we rely on a combination of patent, trademark, copyright and trade secret laws, confidentiality agreements with our employees and third parties, and protective contractual provisions. Further, we can give no assurances that infringement or invalidity claims (or claims for indemnification resulting from infringement claims) will not be asserted or prosecuted against us or that any such assertions or prosecutions will not materially adversely affect our business. Regardless of whether any such claims are valid or can be successfully asserted, defending against such claims could cause us to incur significant costs and could divert resources away from our other activities. In addition, assertion of infringement claims could result in injunctions that prevent us from distributing our products. Despite these efforts, any of the following may reduce the value of our intellectual property:
• our applications for patents, trademarks and copyrights relating to our business may not be granted and, if granted, may be challenged or invalidated;
• issued trademarks, copyrights, or patents may not provide us with any competitive advantages;


9


• our efforts to protect our intellectual property rights may not be effective in preventing misappropriation of our technology; or
• our efforts may not prevent the development and design by others of products or technologies similar to or competitive with, or superior to those we develop.
In addition, we may not be able to effectively protect our intellectual property rights in certain foreign countries where we may do business in the future or from which competitors may operate. While we have numerous pending international patents, obtaining such patents will not necessarily protect our technology or prevent our international competitors from developing similar products or technologies. Our inability to adequately protect our proprietary rights would have a negative impact on our operations and revenues.
If we are forced to litigate to defend our intellectual property rights, or to defend claims by third parties against us relating to intellectual property rights, legal fees and court injunctions could adversely affect our financial condition or end our business.
Disputes regarding the ownership of technologies and intellectual property rights are common and likely to arise in the future. We have already begun legal proceedings against Microsoft to defend our intellectual property rights, and we may be forced to litigate against others to enforce or defend our intellectual property rights, to protect our trade secrets or to determine the validity and scope of other parties’ proprietary rights. Any such litigation is likely to be very costly and distract our management from focusing on operating our business. The existence and outcome of any such litigation could harm our business. Additionally, any such costs we incur to defend or protect our intellectual property rights could greatly impact our financial condition.
The laws governing online secure communications are largely unsettled, and if we become subject to various government regulations, costs associated with those regulations may materially adversely affect our business.
The current regulatory environment for our services remains unclear. We can give no assurance that our planned product offerings will be in compliance with local, stateand/or U.S. Federal laws or other laws. Further, we can give no assurance that we will not unintentionally violate such laws or that such laws will not be modified, or that new laws will be enacted in the future which would cause us to be in violation of such laws.
VoIP services are not currently subject to all of the same regulations that apply to traditional telephony. It is possible that federal and state legislatures may seek to impose increased fees and administrative burdens on VoIP, data and video providers. The U.S. Federal Communications Commission may seek to impose traditional telephony requirements such as disability access requirements, consumer protection requirements, number assignment and portability requirements and other obligations. Such regulations could result in substantial costs depending on the technical changes required to accommodate the requirements, and any increased costs could erode the pricing advantage over competing forms of communication and adversely affect consumer adoption of VoIP products generally.
The use of the internet and private IP networks to provide voice, video and other forms of real-time, two-way communications services is a relatively recent development. Although the provisioning of such services is currently permitted by U.S. law and is largely unregulated within the United States, several foreign governments have adopted lawsand/or regulations that could restrict or prohibit the provisioning of voice communications services over the internet or private IP networks. More aggressive domestic or international regulation of the internet in general, and internet telephony providers and services specifically, may materially and adversely affect our business, financial condition, operating results and future prospects, particularly if increased numbers of governments impose regulations restricting the use and sale of IP telephony services.
In addition to regulations addressing internet telephony and broadband services, other regulatory issues relating to the internet in general could affect our ability to provide our planned security solutions. Congress has adopted legislation that regulates certain aspects of the internet, including online content, user privacy, taxation, liability for third-party activities and jurisdiction. In addition, a number of initiatives pending in Congress and state


10


legislatures would prohibit or restrict advertising or sale of certain products and services on the internet, which may have the effect of raising the cost of doing business on the internet generally.
Telephone carriers have petitioned governmental agencies to enforce regulatory tariffs, which, if granted, would increase the cost of online communication, and such increase in cost may impede the growth of online communication and adversely affect our business.
The growing popularity and use of secure communications has burdened the existing telecommunications infrastructures, and many high traffic areas have begun to experience interruptions in service. As a result, certain local telephone carriers have petitioned governmental agencies to enforce regulatory tariffs on IP telephony traffic that crosses over the traditional telephone networks. If any of these petitions or the relief that they seek is granted, the costs of communicating via online could increase substantially, potentially adversely affecting the growth in the use of online secure communications. Any of these developments could have an adverse effect on our business.
If we expand into international markets, our inexperience outside the United States would increase the risk that our international expansion efforts will not be successful, which would in turn limit our prospects for growth.
We may explore expanding our business to outside the United States. Expansion into international markets requires significant management attention and financial resources. In addition, we may face the following risks associated with any expansion outside the United States:
• challenges caused by distance, language and cultural differences;
• legal, legislative and regulatory restrictions;
• currency exchange rate fluctuations;
• economic instability;
• longer payment cycles in some countries;
• credit risk and higher levels of payment fraud;
• potentially adverse tax consequences; and
• other higher costs associated with doing business internationally.
These risks could harm our international expansion efforts, which would in turn harm our business prospects.
The departure of Kendall Larsen, our Chief Executive Officer and President, and/or other key personnel could compromise our ability to execute our strategic plan and may result in additional severance costs to us.
Our success largely depends on the skills, experience and efforts of our key personnel, including Kendall Larsen, our Chief Executive Officer and President. The loss of Mr. Larsen, or our failure to retain other key personnel, would jeopardize our ability to execute our strategic plan and materially harm our business.
We will need to recruit and retain additional qualified personnel to successfully grow our business.
Our future success will depend in part on our ability to attract and retain qualified operations, marketing and sales personnel as well as engineers. Inability to attract and retain such personnel could adversely affect our business. We expect to face competition in the recruitment of qualified personnel, and we can provide no assurance that we will attract or retain such personnel.
We will incur significant costs as a result of being a public company.
As a public company, we will incur significant legal, accounting and other expenses that VirnetX, Inc. did not incur as a private company. We expect the laws, rules and regulations governing public companies to increase our


11


legal and financial compliance costs and to make some activities more time-consuming and costly, and these costs could be material to us.
In connection with audits of our financial statements, our independent auditors identified material weaknesses in our internal controls over financial reporting.
During the course of their audit of our 2007 financial statements, our independent auditors concluded that our internal controls over financial reporting suffered from certain “material weaknesses” as defined in standards established by the Public Company Accounting Oversight Board and the American Institute of Certified Public Accountants.
Farber Hass Hurley LLP noted the following matters involving our internal control over financial reporting that are considered to be material weaknesses in connection with their audit of our 2007 financial statements:
• Farber Hass Hurley LLP proposed, and we recorded, adjustments to our accounting for equity transactions during 2007.
• Farber Hass Hurley LLP noted that our controls over financial disclosures need to be improved.
• Farber Hass Hurley LLP noted that certain expenses within 2007 were not timely accrued prior to receipt of billing statements.
Prior to becoming our subsidiary, VirnetX, Inc. was a development stage, privately held company that historically did not formalize or document internal controls over financial reporting, utilized the cash basis of accounting and was not required to have its financial statements audited or reviewed. Prior to becoming our subsidiary, VirnetX, Inc. engaged independent auditors to audit its financial statements for certain prior periods. During the course of that audit, VirnetX, Inc.’s independent auditors concluded that VirnetX, Inc.’s internal controls over financial reporting suffered from certain “material weaknesses” and “significant deficiencies” over its internal controls over financial reporting as defined in standards established by the Public Company Accounting Oversight Board and the American Institute of Certified Public Accountants. Because VirnetX, Inc. is now our wholly-owned subsidiary, the material weaknesses in VirnetX, Inc.’s internal controls over financial reporting have resulted in our having material weaknesses and significant deficiencies in our internal controls over financial reporting. We have commenced a process of developing, adopting and implementing policies and procedures to address such material weaknesses. However, that process has been and may continue to be time consuming and costly and there is no assurance as to when we will effectively address such material weaknesses and significant deficiencies.
Our inability to become compliant with the internal controls requirements of Section 404 of the Sarbanes Oxley Act could negatively affect our stock price and limit our ability to raise additional financing.
Burr, Pilger & Mayer LLP, the independent audit firm retained to audit the 2005 and 2006 financial statements for our principal operating subsidiary resigned on October 26, 2007. The reason for the resignation was concern that we would not become compliant with the internal controls requirements of Section 404 of the Sarbanes Oxley Act by December 31, 2007 and due to an insufficient quantity of experienced resources involved with the financial reporting and period closing process. Our management has concluded that, as of December 31, 2007, we were not compliant with these internal control requirements and, although we are pursuing compliance, there can be no assurance we will be successful in becoming compliant in future periods. Our lack of compliance with internal controls requirements of Section 404 of the Sarbanes Oxley Act could negatively affect our stock price, make us less attractive to our stockholders, jeopardize our listing status and limit our ability to raise additional financing.
Risks related to our stock
Trading in our common stock is limited and the price of our common stock may be subject to substantial volatility.
Our common stock is listed on the American Stock Exchange, or AMEX, but its daily trading volume has been limited and sporadic. Also, there can be no assurance that we will remain listed on the AMEX. Additionally, the


12


price of our common stock may be volatile as a result of a number of factors, including, but not limited to, the following:
• developments in our pending litigation against Microsoft;
• quarterly variations in our operating results;
• large purchases or sales of common stock;
• actual or anticipated announcements of new products or services by us or competitors;
• general conditions in the markets in which we compete; and
• economic and financial conditions.
Because ownership of our common shares is concentrated, you and other investors will have minimal influence on stockholder decisions.
As of June 30, 2008, our officers and directors owned an aggregate of 9,028,979 shares, or 25.87% of our outstanding common stock. In addition, a group of stockholders that, as of December 31, 2007, held 4,766,666 shares, or 13.7% of our outstanding common stock, have entered into a voting agreement with us that requires them to vote all of their shares of our voting stock in favor of the director nominees approved by our Board of Directors at each director election going forward, and in a manner that is proportional to the votes cast by all other voting shares as to any other matters submitted to the stockholders for a vote. As a result, our existing officers and directors could significantly influence shareholder actions of which you disapprove or that are contrary to your interests. This ability to exercise significant influence could prevent or significantly delay another company from acquiring or merging with us.
Large portions of our outstanding common shares have been released from contractual restrictions on July 5, 2008 and additional shares will be released on December 31, 2008, and sales of those shares may drive down the price of our stock.
Stockholders who received our common shares as a result of the merger between PASW, Inc. and VirnetX, Inc. entered into a CompanyLock-Up Agreement restricting sales of their shares until July 5, 2008. Subsequently, certain of our stockholders signed aLock-Up Agreement with our underwriter in connection with our recent public offering, which restricts sales of their shares until December 31, 2008. Only shares held by our directors and officers currently remain subject to alock-up agreement and these shares will be released from thelock-up on December 31, 2008. Sales of recently released shares may drive down the price of our stock. The 15,796,786 shares that became eligible for trading on July 5, 2008 represent 45.3% of our outstanding common stock as of May 4, 2008. The 8,489,545 shares that will subsequently become eligible for trading on December 31, 2008 represent 24.3% of our outstanding common stock as of May 4, 2008.
Our protective provisions could make it more difficult for a third party to successfully acquire us even if you would like to sell your shares to them.
We have a number of protective provisions that could delay, discourage or prevent a third party from acquiring control of us without the approval of our Board of Directors. Our protective provisions include:
• A staggered Board of Directors:  this means that only one or two directors (since we have a five-person Board of Directors) will be up for election at any given annual meeting. This has the effect of delaying the ability of stockholders to effect a change in control of us since it would take two annual meetings to effectively replace at least three directors which represents a majority of the Board of Directors.
• Blank check preferred stock:  our Board of Directors has the authority to establish the rights, preferences and privileges of our 10,000,000 authorized, but unissued, shares of preferred stock. Therefore, this stock may be issued at the discretion of our Board of Directors with preferences over your shares of our common stock in a manner that is materially dilutive to existing stockholders. In addition, blank check preferred stock


13


can be used to create a “poison pill” which is designed to deter a hostile bidder from buying a controlling interest in our stock without the approval of our Board of Directors. We have not adopted such a “poison pill;” but our Board of Directors has the ability to do so in the future, very rapidly and without stockholder approval.
• Advance notice requirements for director nominations and for new business to be brought up at stockholder meetings:  stockholders wishing to submit director nominations or raise matters to a vote of the stockholders must provide notice to us within very specific date windows and in very specific form in order to have the matter voted on at a stockholder meeting. This has the effect of giving our Board of Directors and management more time to react to stockholder proposals generally and could also have the effect of disregarding a stockholder proposal or deferring it to a subsequent meeting to the extent such proposal is not raised properly.
• No stockholder actions by written consent:  no stockholder or group of stockholders may take actions rapidly and without prior notice to our Board of Directors and management or to the minority stockholders. Along with the advance notice requirements described above, this provision also gives our Board of Directors and management more time to react to proposed stockholder actions.
• Super majority requirement for stockholder amendments to the By-laws:stockholder proposals to alter or amend our By-laws or to adopt new By-laws can only be approved by the affirmative vote of at least 662/3% of the outstanding shares.
• Elimination of the ability of stockholders to call a special meeting of the stockholders:  only the Board of Directors or management can call special meetings of the stockholders. This could mean that stockholders, even those who represent a significant block of our shares, may need to wait for the annual meeting before nominating directors or raising other business proposals to be voted on by the stockholders.
Securities analysts may not cover our common stock and this may have a negative impact on our common stock’s market price.
The trading market for our common stock may depend on the research and reports that securities analysts publish about us or our business. We do not have any control over these analysts. There is no guarantee that securities analysts will cover our common stock. If securities analysts do not cover our common stock, the lack of research coverage may adversely affect our common stock’s market price. If we are covered by securities analysts, and our stock is downgraded, our stock price would likely decline. If one or more of these analysts ceases to cover us or fails to publish regularly reports on us, we could lose or fail to gain visibility in the financial markets, which could cause our stock price or trading volume to decline.
We may seek to raise additional funds, finance acquisitions or develop strategic relationships by issuing capital stock that would dilute your ownership.
We have financed our operations, and we expect to continue to finance our operations, acquisitions and develop strategic relationships, by issuing equity or convertible debt securities, which could significantly reduce the percentage ownership of our existing stockholders. Furthermore, any newly issued securities could have rights, preferences and privileges senior to those of our existing stock. Moreover, any issuances by us of equity securities may be at or below the prevailing market price of our stock and in any event may have a dilutive impact on your ownership interest, which could cause the market price of stock to decline. We may also raise additional funds through the incurrence of debt or the issuance or sale of other securities or instruments senior to our common shares.


14


The holders of any debt securities or instruments we may issue would have rights superior to the rights of our common stockholders.
We have no current intention of declaring or paying any cash dividends on our common stock.
We do not plan to declare or pay any cash dividends on our common stock. Our current policy is to use all funds and any earnings in the operation and expansion of our business.
FORWARD-LOOKING STATEMENTS
This prospectus includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. All statements other than statements of historical facts contained in this prospectus, including statements regarding our future financial position, business strategy and plans and objectives of management for future operations, are forward-looking statements. The words “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “expect” and similar expressions, as they relate to us, are intended to identify forward-looking statements. We have based these forward-looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our financial condition, results of operations, business strategy and financial needs. These forward-looking statements are subject to a number of risks, uncertainties and assumptions described in “Risk Factors” and elsewhere in this prospectus. These risks are not exhaustive. Other sections of this prospectus include additional factors which could adversely impact our business and financial performance. Moreover, we operate in a very competitive and rapidly changing environment. New risk factors emerge from time to time and it is not possible for our management to predict all risk factors, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. You should not rely upon forward-looking statements as predictions of future events. We cannot assure you that the events and circumstances reflected in the forward-looking statements will be achieved or occur and actual results could differ materially from those projected in the forward-looking statements.
USE OF PROCEEDS
We will not receive any of the proceeds from the sale of shares of our common stock in the aggregate amount of $35,000,000 at an assumed offering price of $3.91 per share, the last reported sale price of our common stock on August 18, 2015 on the NYSE MKT LLC, and after deducting commissions and estimated offering expenses, our as adjusted net tangible book value as of June 30, 2015 would have been approximately $55,607,000 or approximately $0.91 per share. This represents an immediate increase in net tangible book value of approximately $0.50 per share to our existing stockholders and an immediate dilution in as adjusted net tangible book value of approximately $3.00 per share to purchasers of our common stock in this offering. See the section entitled “Dilution” below for a more detailed discussion of the dilution you will incur if you purchase common stock in this offering.
You may experience future dilution as a result of future equity offerings.
In order to raise additional capital, we may in the future offer additional shares of our common stock or other securities convertible into or exchangeable for our common stock.  We cannot assure you that we will be able to sell shares or other securities in any other offering at a price per share that is equal to or greater than the price per share paid by investors in this offering, and investors purchasing shares or other securities in the future could have rights superior to existing stockholders.  The price per share at which we sell additional shares of our common stock or other securities convertible into or exchangeable for our common stock in future transactions may be higher or lower than the price per share in this offering.  As of August 4, 2015, approximately 6,454,436 shares of common stock that are either subject to outstanding options, issuable upon vesting of outstanding restricted stock units, reserved for future issuance under our equity incentive plans or subject to outstanding warrants are eligible for sale in the public market to the extent permitted by the selling stockholders. We will bear all costs, expensesprovisions of various vesting schedules and feesRule 144 and Rule 701 under the Securities Act.
If we sell additional equity or debt securities to fund our operations, it may impose restrictions on our business.
In order to raise additional funds to support our operations, we may sell additional equity or debt securities, which may impose restrictive covenants that adversely impact our business. The incurrence of indebtedness would result in connection withincreased fixed payment obligations and could also result in restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. If we are unable to expand our operations or otherwise capitalize on o business opportunities due to such restrictions, our business, financial condition and results of operations could be materially adversely affected.

Future sales of our common stock in the registrationpublic market or other financings could cause our stock price to fall.
Sales of a substantial number of shares of our common stock in the public market, the perception that these sales might occur or other financings, could depress the market price of our common stock and could impair our ability to raise capital through the sale of additional equity securities. A substantial majority of the outstanding shares of our common stock are, all of the shares sold in this offering upon issuance will be, soldfreely tradable without restriction or further registration under the Securities Act unless these shares are owned or purchased by "affiliates" as that term is defined in Rule 144 under the selling stockholders. The selling stockholders will bear all commissions and discounts, if any, attributable to their respective sales of shares.Securities Act.
 
DIVIDEND POLICYBecause we do not intend to declare cash dividends on our shares of common stock in the foreseeable future, stockholders must rely on appreciation of the value of our common stock for any return on their investment.
 
We havedo not anticipate declaring or paying any cash dividends in the past paid,foreseeable future. In addition, the terms of our existing debt agreements preclude us from paying dividends. As a result, we expect that only appreciation of the price of our common stock, if any, will provide a return to investors in the offering for the foreseeable future.
The common stock offered hereby will be sold in "at-the-market" offerings, and investors who buy shares at different times will likely pay different prices.
Investors who purchase shares in this offering at different times will likely pay different prices, and so may experience different outcomes in their investment results. We will have discretion, subject to market demand, to vary the timing, prices, and numbers of shares sold, and there is no minimum or maximum sales price. Investors may experience a decline in the value of their shares as a result of share sales made at prices lower than the prices they paid.
The actual number of shares we will issue under the sales agreement, at any one time or in total, is uncertain.
Subject to certain limitations in the sales agreement and compliance with applicable law, we have the discretion to deliver a sales notice to Cowen at any time throughout the term of the sales agreement.  The number of shares that are sold by Cowen after delivering a sales notice will fluctuate based on the market price of the common shares during the sales period and limits we set with Cowen.  Because the price per share of each share sold will fluctuate based on the market price of our common stock during the sales period, it is not possible at this stage to predict the number of shares that will be ultimately issued.

USE OF PROCEEDS
We expect to use the net proceeds from the sale of securities for Gabriel product development and marketing, and general corporate purposes, which may include working capital, capital expenditures, other corporate expenses and acquisitions of complementary products, technologies or businesses. The timing and amount of our actual expenditures will be based on many factors, including cash flows from operations and the anticipated growth of our business. Our management team will have broad discretion to allocate the net proceeds of the offering. Pending their ultimate use, we intend to invest the net proceeds in short-term investment-grade, interest-bearing instruments.

DIVIDEND POLICY
We do not expect for the foreseeable future to pay dividends on our common stock. Instead, we anticipate that all of our earnings, if any, in the foreseeable future will be used for working capital and other general corporate purposes. Any future determination to pay dividends on our common stock will be at the discretion of our board of directors and will depend upon, among other factors, our results of operations, financial condition, capital requirements and contractual restrictions.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS
S-8

DILUTION
 
If you invest in our common stock, your interest will be diluted to the extent of the difference between the price per share of our common stock you pay in this offering and the as adjusted net tangible book value per share of our common stock immediately after this offering.
Our net tangible book value as of June 30, 2015 was approximately $21,657,000, or $0.41 per share.  Net tangible book value per share is determined by dividing our total tangible assets, less total liabilities, by the number of shares of our common stock outstanding as of June 30, 2015.  Dilution in net tangible book value per share represents the difference between the amount per share paid by purchasers of shares of common stock in this offering and the as adjusted net tangible book value per share of our common stock immediately after giving effect to this offering.
After giving effect to the sale of our common stock in the aggregate amount of $35,000,000 in this offering at an assumed offering price of $3.91, the last reported sale price of our common stock on the NYSE MKT LLC on August 18, 2015, and after deducting commissions and estimated aggregate offering expenses payable by us, our as adjusted net tangible book value as of August 18, 2015 would have been approximately $55,607,000, or $0.91 per share.  This report,represents an immediate increase in net tangible book value of $0.50 per share to existing stockholders and immediate dilution in net tangible book value of $3.00 per share to new investors purchasing our common stock in this offering.
The following table illustrates this dilution on a per share basis. The as adjusted information is illustrative only and will adjust based on the actual price to the public, the actual number of shares sold and other terms of the offering determined at the time shares of our common stock are sold pursuant to this prospectus. The shares sold in this offering, if any, will be sold from time to time at various prices.
Assumed public offering price per share   $3.91 
Net tangible book value per share as of June 30, 2015 $0.41     
Increase per share attributable to new investors  0.50     
As adjusted net tangible book value per share after this offering       0.91 
Dilution per share to new investors       3.00 
A $1.00 increase (decrease) in the assumed offering price of $3.91 per share, which was the last reported sale price of our common stock on the NYSE MKT LLC on August 18, 2015, would increase (decrease) dilution per share to purchasers by approximately $0.97 ($0.96), after deducting commissions and estimated offering expenses payable by us.
To the extent that outstanding options or warrants are exercised or outstanding restricted stock units vest, investors purchasing our common stock in this offering will experience further dilution.  In addition, we may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans.  To the extent that we raise additional capital through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our stockholders.
PLAN OF DISTRIBUTION
We have entered into a sales agreement with Cowen under which we may issue and sell shares of our common stock having an aggregate gross sales price of up to $35,000,000 from time to time through Cowen acting as agent.  The sales agreement has been filed as an exhibit to our registration statement on Form S-3 of which this prospectus supplement forms a part.
Upon delivery of a placement notice and subject to the terms and conditions of the sales agreement, Cowen may sell our common stock by any method permitted by law deemed to be an “at-the-market” offering as defined in Rule 415 promulgated under the Securities Act, including sales made directly on the NYSE MKT LLC on any other existing trading market for our common stock or to or through a market maker.  Cowen may also sell our common stock by any other method permitted by law, including in privately negotiated transactions.  We may instruct Cowen not to sell common stock if the sales cannot be effected at or above the price designated by us from time to time.  We or Cowen may suspend the offering of common stock upon notice and subject to other conditions.
Each time we wish to issue and sell common stock under the sales agreement, we will notify Cowen of the number of shares to be issued, the dates on which such sales are anticipated to be made, any minimum price below which sales may not be made and other sales parameters as we deem appropriate.  Once we have so instructed Cowen, unless Cowen declines to accept the terms of the notice, Cowen has agreed to use its commercially reasonable efforts consistent with its normal trading and sales practices to sell such shares up to the amount specified on such terms.  The obligations of Cowen under the sales agreement to sell our common stock are subject to a number of conditions that we must meet.
We will pay Cowen commissions, in cash, for its services in acting as agent in the sale of our common stock.  Cowen will be entitled to compensation at a fixed commission rate of up to 3.0% of the gross sales price per share sold.  Because there is no minimum offering amount required as a condition to close this Management’s Discussionoffering, the actual total public offering amount, commissions and Analysisproceeds to us, if any, are not determinable at this time.  We have also agreed to reimburse Cowen for certain specified expenses, including the fees and disbursements of Financial Conditionits legal counsel, in an amount not to exceed $125,000.  We estimate that the total expenses for the offering, excluding discounts and Resultscommissions payable to Cowen under the terms of Operations contains “forward-looking” statementsthe sales agreement, will be approximately $606,000.
Settlement for sales of common stock will generally occur on the third business day following the date on which any sales are made, or on some other date that is agreed upon by us and Cowen in connection with a particular transaction, in return for payment of the net proceeds to us.  Sales of our common stock as contemplated in this prospectus supplement will be settled through the facilities of The Depository Trust Company or by such other means as we and Cowen may agree upon.  There is no arrangement for funds to be received in an escrow, trust or similar arrangement.
Cowen will use its commercially reasonable efforts, consistent with its sales and trading practices, to solicit offers to purchase the common stock shares under the terms and subject to the conditions set forth in the sales agreement.  In connection with the sale of the common stock on our behalf, Cowen may, and will with respect to sales effected in an “at the market” offering, be deemed to be an “underwriter” within the meaning of the Private Securities Litigation Reform Act and the compensation of 1995, which provides a “safe harbor” for statements about future events, productsCowen will be deemed to be underwriting commissions or discounts.  We have agreed to provide indemnification and future financial performance that are based oncontribution to Cowen against certain civil liabilities, including liabilities under the beliefsSecurities Act.
The offering of our common stock pursuant to the sales agreement will terminate upon the earlier of (1) the sale of all shares of our management. Except forcommon stock subject to the historical information contained herein, the outcomesales agreement, or (2) termination of the events describedsales agreement as permitted therein.  We and Cowen may each terminate the sales agreement at any time upon 10 days’ prior notice.
Cowen and its affiliates may in these forward-looking statementsthe future provide various investment banking, commercial banking and other financial services for us and our affiliates, for which services they may in the future receive customary fees.  To the extent required by Regulation M, Cowen will not engage in any market making activities involving our common stock while the offering is subject to risks and uncertainties. See “Risk Factors” for a discussionongoing under this prospectus supplement.

Research and Development Expenses
Research and development costs include expenses paid to outside development consultants and compensation-related expenses for our engineering staff. Research and development costs are expensed as incurred.
Corporate Information
 
Our researchexecutive offices are located at 308 Dorla Court, Suite 206, Zephyr Cove, Nevada 89448, and development expenses increased by $149,645 to $417,823 forour telephone number at that address is (775) 548-1785. We maintain a website on the six months ended June 30, 2008, from $268,178 for the six months ended June 30, 2007. This increase is primarily due to increased engineering activities for product developmentInternet at www.virnetx.com. Our website, and the additioninformation contained therein, is not a part of three engineers. We expect research and development expenses to increase as employees are hired to provide in-house research and development. While we expect to use outside contractors for additional product development on a limited basis, we expect those costs to remain level or decline.this prospectus.

General and Administrative Expenses
General and administrative expenses include management and administrative personnel, as well as outside legal, accounting, and consulting services.
Our general and administrative expenses increased by $4,264,025, to $5,962,272 for the six months ended June 30, 2008 from $1,698,247 for the six month period ended June 30, 2007.
Within general and administrative expenses, legal fees increased by $2,008,585 to $3,263,306 for the six months ended June 30, 2008, from $1,254,721 for the six months ended June 30, 2007. The increase in fees incurred was due primarily to our patent infringement litigation against Microsoft.
Also within general and administrative expenses, stock-based compensation expense increased by $1,103,607 to $1,145,322 for the six months ended June 30, 2008, from $41,715 for the six month period ended June 30, 2007. The increase was due principally to expenses related to stock options granted to our employees and directors, an increased number of employees and resources we added to comply with the requirements associated with being an SEC reporting company.
Fiscal Year Ended December 31, 2007 Compared to the Fiscal Year Ended
December 31, 2006 and Inception Through December 31, 2005
Results of Operations
Revenue — Royalties
We generated only nominal revenue of $74,866 during the period from July 5, 2007 (the closing date of the merger between us and VirnetX, Inc.) to December 31, 2007. We generated no revenue prior to July 5, 2007. Our revenue in 2007, was solely limited to the royalties earned under our single license agreement through our Japan subsidiary. We expect the revenue from this license to decrease substantially in the future. We do not intend to seek additional licenses or other revenue through our Japan subsidiary.
Research and Development Expenses
Research and development costs include expenses paid to outside development consultants and compensation-related expenses for our engineering staff. Research and development costs are expensed as incurred.
Our research and development expenses increased from $56,000 for the period from August 2, 2005 (date of inception) to December 31, 2005 to $554,187 for 2006 and to $684,316 for 2007, primarily as a result of increased engineering activities for product development. We expect research and development expenses to increase as employees are hired to provide in-house research and development. While we expect to use outside contractors for additional product development on a limited basis, we expect those costs to remain level or decline.
General and Administrative Expenses
General and administrative expenses include management and administrative personnel, as well as outside legal, accounting, and consulting services.
Our general and administrative expenses increased from $826,478 for the period from August 2, 2005 (date of inception) to December 31, 2005, to $853,488 for 2006 and to $8,040,894 for 2007.
Within general and administrative expenses, professional fees, primarily legal fees, increased from $12,481 in the period from August 2, 2005 (date of inception) to December 31, 2005 to $133,199 in 2006 and to $5,286,525 in


18


2007. The fees were incurred to pursue the litigation with Microsoft, assist in the merger between VirnetX, Inc. and VirnetX Holding Corporation, audit the financial statements, assist in obtaining financing and to assist in contract negotiations and in general corporate matters. Legal fees may continue to increase as our patent infringement litigation moves forward and we incur the costs associated with being an SEC reporting company.
Also within general and administrative expenses, compensation expenses changed from $799,920 in the period from August 2, 2005 (date of inception) to December 31, 2005 to $613,757 in 2006 and to $2,152,000 in 2007. The compensation expense was higher in 2005 than 2006 due to the higher proportion of stock based compensation expense in 2005. The increase from 2006 to 2007 is due principally to stock-based compensation expense related to stock options granted to our employees and directors and an increase in the number of our employees as we added resources to comply with reporting requirements.
Other general and administrative expenses increased from $14,077 in the period from August 2, 2005 (date of inception) to December 31, 2005 to $106,532 in 2006 and to $602,639 in 2007 as we incurred costs related to building our infrastructure, litigation support and completing the merger.
Liquidity and Capital Resources
We are in the development stage and have raised capital since our inception through the issuance of our equity securities. As of June 30, 2008, we had approximately $4,208,722 in cash. We expect to finance future cash needs primarily through proceeds from equity or debt financings, loans,and/or collaborative agreements with corporate partners. We have used the net proceeds from the sale of common and preferred stock for general corporate purposes, which have included funding research and development, litigation efforts and working capital needs.
We anticipate that our existing cash and cash equivalents will be sufficient to fund operations for at least the next 6 months. We believe that our 2008 cash requirement to fund our operations will average approximately $660,000 per month and, in 2009 we expect to increase to approximately $850,000 per month. We anticipate our projected monthly cash requirements will increase significantly as we increase our expenditures for:
• our lawsuit against Microsoft;
• infrastructure;
• sales and marketing;
• research and development;
• personnel; and
• general business enhancements.
The process of developing new security solutions is inherently complex, time-consuming, expensive and uncertain. We must make long-term investments and commit significant resources before knowing whether our development programs will result in products that will achieve market acceptance. Product candidates that may appear to be promising at all stages of development may not reach the market for a number of reasons. Product candidates may be found ineffective or may take longer to progress through the beta trials than had been anticipated, may not be able to achieve the pre-defined endpoint due to changes in the environment, may fail to receive necessary approvals, may prove impracticable to manufacture in commercial quantities at reasonable cost and with acceptable quality, or may fail to achieve market acceptance. For these reasons, we are unable to predict the period in which material net cash inflows will commence with respect to our licensing program under development and our software products under development.
To obtain additional capital when needed, we expect to evaluate alternative financing sources, including, but not limited to, the issuance of equity or debt securities, corporate alliances, joint ventures and licensing agreements; however, there can be no assurance that funding will be available on favorable terms, if at all. We cannot assure you that we will successfully commercialize our products under development or that our products, if successfully developed, will generate revenues sufficient to enable us to earn a profit. If we are unable to obtain additional capital, we may be required to cease operations or to reduce cash used in our business, including the termination of development efforts that may appear to be promising, the sale of our patent portfolio or other assets, the abandonment of our litigation with Microsoft or others and the reduction in overall operating activities.
Off-Balance Sheet Arrangements
There have been no material changes to the information provided in our Annual Report onForm 10-K for the fiscal year ended December 31, 2007 regarding off-balance sheet arrangements.

BUSINESS
Corporate Overview and History
Our predecessor corporation was incorporated in the State of California in November 1992. We were incorporated in the State of Delaware in April 2007 and on May 30,August 2005.  In November 2006, VirnetX acquired certain patents from Leidos, Inc.  In July 2007, we filedeffected a certificatereverse merger between PASW, Inc. and VirnetX, which became our principal operating subsidiary.  As a result of this merger, in Delaware pursuantthe former security holders of VirnetX came to which we changedown a majority of our domicile from California to Delaware.outstanding common stock.  On October 29, 2007, we changed our name from PASW, Inc. to VirnetX Holding Corporation. From

This prospectus includes product names, trade names and trademarks of developingother companies. All other product names, trade names and licensing software that enabled internet and web based communications. Astrademarks appearing in this prospectus are the property of January 31, 2003, we sold all of our operating assets, and since such time our only source of revenue has been derived from nominal royalties payable to our wholly-owned Japan subsidiary, Network Research Corp. Japan, Ltd. pursuant to the terms of a single license agreement. In addition to our Japan subsidiary, we have three other wholly-owned subsidiaries, two of which are California corporations and the other of which is incorporated under the laws of the United Kingdom. These other subsidiaries are currently inactive.their respective holders.

The Securities We have had substantially no day to day operations since we sold all of our operating assets on January 31, 2003. We acquired VirnetX as a wholly-owned subsidiary on July 5, 2007 and ceased being a shell company. Additionally, pursuant to the merger with VirnetX, we experienced a change in control, with the former securityholders of VirnetX acquiring control of VirnetX Holding Corporation.
VirnetX was incorporated in the State of Delaware in August 2005. It is a development stage company that was formed to commercialize a patent portfolio for providing solutions for secure real-time communications such as instant messaging, or “IM,” and voice over internet protocol, or “VoIP.” VirnetX acquired certain patents from Science Applications International Corporation, a systems, solutions and technical services company based in San Diego, California (better known as “SAIC”) and in February 2007 commenced a lawsuit against Microsoft Corporation alleging infringement of three of our patents.
Principal Products and Services
Technology and Solutions Business
Our primary strategy for our technology and solutions business is to commercialize our patented technology in the area of secure real-time communication. We are developing technology for:
• “single-click” and “zero-click” security solutions for real-time communications; and
• “end-to-end” security for VoIP, video conferencing and other types ofpeer-to-peer collaboration without degradation in quality of service.
In addition, we expect to continue to generate nominal royalties payable to our Japan subsidiary pursuant to the terms of a single license agreement. This license agreement was entered into in 1994 and, pursuant to its terms, it automatically renews on an annual basis unless either party terminates as a result of a breach by the other party or the licensee going out of business.
Contract Services Business
Our primary strategy for our contract services business is to leverage our research and development group to provide contract research, prototyping, systems integration and technical services to numerous branches of the U.S. Federal government, network service providers and other OEM partners. Our team is staffed with nationally accredited scientists who have experience with research and development projects concerning industry-wide security solutions as well as national security. We intend to provide these contract services to assist the research and development efforts of our corporate and OEM developers by providing outsourced research, deployment and testing services designed to secure and simplify networks.May Offer
 
We believe thatmay offer up to $100,000,000 of common stock, preferred stock, depositary shares, warrants, debt securities and units in one or more offerings and in any combination. This prospectus provides you with a general description of the revenue generated by our contract services business will eventually partially offset the costs of our technology and solutions business andsecurities we may offer.  A prospectus supplement, which we will provide us witheach time we offer securities, will describe the opportunity to generate future strategic relationshipsspecific amounts, prices and licensing opportunities. We also anticipate that future contract services projects will enable us to develop promising new technologies that can be commercialized through our technology and solutions business.

Marketing and Salesterms of these securities.
 
We do not anticipate launching any new products inmay sell the marketplace until the First Quarter of 2009 at the earliest. We intendsecurities to partner with hardware and software manufacturers and network operatorsor through underwriters, dealers or agents or directly to operationalize and commercialize our products.
Our contract services business expects to generate new customers primarily through professional relationships and referrals.
Customers and Distribution
We are a development stage company with significant investments in research and development, and we currently do not sellpurchasers or distribute any of our products. We expect that our contract services customers will consist primarily of the U.S. Federal government, network service providers and other OEM companies. Our contract services business has targeted five customers who we expect will represent more than 80% of our future contract services revenue for the foreseeable future.
We have made a strategic decision to selectively limit new customers in our contract services business in order to focus on the development of new products in our technology and solutions business.
Competition
The enterprise telephony market has transitioned from being circuit-switched to packet-switched in large part to eliminate the requirement of running separate voice and data networks. The IP telephony industry conceived session initiation protocol (better known as “SIP”) to improve the setup and handling of telephone calls, and computer technologists have quickly adopted SIP as a protocol to simplify all forms of real-time communications. The rapid market adoption of SIP has created the need to secure SIP before it can reach the global mainstream.
SIP is a growing protocol used for real-time communication, and we anticipate that SIP will represent a significant portion of the worldwide IP telephony market over the next five years. It has become the basis for “next generation networks” for unified messaging and communication. SIP uses existing protocols and services, including domain name system, or “DNS,” real-time transport protocol, or “RTP,” the session description protocol, or “SDP,” and transport layer security, or “TLS.”
A number of vendors are providing solutions for secure real-time communications. These solutions can be grouped under three main categories:
• A session border controller, or “SBC,” is a device used in some VoIP networks to exert control over the signaling and media streams involved in setting up, conducting, and tearing down calls. SBCs are put into the signalingand/or media path between the calling and called party. In some cases, the SBC acts as the called VoIP phone and places a second call to the called party. The effect is that the signaling traffic not only crosses the SBC but the media traffic (voice, video etc.) crosses as well. We believe the security provided by SBC is limited because the SBC can extend the length of the media path (the path of media packets through the network) significantly and may break theend-to-end transparency.
• SIP firewalls (or SIP-aware firewalls) and application layer gateways manage and protect the traffic, flow and quality of VoIP and other SIP-related communications. They perform real-time network address translation (better known as “NAT”) and dynamic firewall functions and support multiple signaling protocols and media transcoding functionality, allowing secure traversal and interconnection of IP media streams across multiple networks.
• VPN technologies provide secure communications over unsecured networks.
We believe our technology and solutions business will compete primarily against these disparate add-on security solution providers. We believe our products will allow our OEM partners to integrate transparent and always on,end-to-end security directly into their unified messaging and communications solutions.
Our contract services business competes primarily against in-house research and development departments of network service providers and other OEM vendors.

Intellectual Property and Patent Rights
Our intellectual property is primarily comprised of trade secrets, proprietary know-how, issued and pending patents and technological innovation.
We have 11 issued U.S. and 8 issued foreign patents, and pending U.S. and foreign patent applications including certain patent applications which VirnetX originally acquired from SAIC. The term of the issued U.S. and foreign patents runs through 2019. Our patents embrace a unique set of functions relating to domain name system, or “DNS,”-based security mechanisms for real-time communication. If we believe that a third party is infringing on our intellectual property rights, we may negotiate with it in an attempt to terminate its infringement. If negotiation is unsuccessful or if we believe that legal action is more appropriate, we may bring a legal action against any party we believe to be infringing on our intellectual property rights so that we may properly protect our rights.
Assignment of Patents
Most of our issued patents were originally acquired from SAIC pursuant to the Assignment Agreement by and between VirnetX and SAIC dated December 21, 2006, and the Patent License and Assignment Agreement by and between VirnetX and SAIC dated August 12, 2005, as amended on November 2, 2006, including documents prepared pursuant to the November amendment, and as further amended on March 12, 2008.

Any payment to SAIC of amounts with respect to such proceeds shall be credited against the $35,000,000 maximum cumulative royalty payable with respect to our revenue-generating activities in our field of use.
Reversion to SAIC Upon Breach or Default.  We must convey, transfer, assign and quitclaim to SAIC all of our right, title and interest in and to the patents or patent applications we acquired from SAIC, upon the first occurrence of the following reversion events:
• our failure to pay SAIC an aggregate cumulative amount of at least $7,500,000 within seven years after January 1, 2007;
• our failure to pay the $50,000 minimum annual royalty that has not been cured within 90 days after our receipt of written notice of such failure; or
• for the period prior to the date of our full payment of the $35,000,000 maximum cumulative royalty, any termination of the August 2005 agreement with SAIC, as amended.


23


If a reversion event occurs due to our failure to pay SAIC an aggregate cumulative amount of at least $7,500,000 within seven years after January 1, 2007, then wesecurities. Each prospectus supplement will receive from SAIC a non-exclusive license to the reverting patents in our field of use.
Rights to Bring and Control Actions for Infringement and Enforcement.  In addition to the exclusive right to bring and control any action or proceeding with respect to infringement or enforcement of our patents, and to collect damages and fees for past, present and future infringement, both in and outside of our field of use, we also have the first right to negotiate with or bring a lawsuit against any and all third parties for purposes of enforcing our patents, regardless of the field of use.
Security Agreement.  We granted SAIC a security interest in some of our intellectual property, including the patents and patent applications we obtained from SAIC, to secure our payment obligations to SAIC described above.
Litigation
We believe Microsoft Corporation is infringing certain of our patents. Accordingly, we commenced a lawsuit against Microsoft on February 15, 2007 by filing a complaint in the United States District Court of the Eastern District of Texas, Tyler Division. Pursuant to the complaint, we allege that Microsoft infringes two of our U.S. patents: U.S. Patent No. 6,502,135 B1, entitled “Agile Network Protocol for Secure Communications with Assured System Availability,” and U.S. Patent No. 6,839,759 B2, entitled “Method for Establishing Secure Communication Link Between Computers of Virtual Private Network Without User Entering Any Cryptographic Information.” On April 5, 2007, we filed an amended complaint specifying certain accused products at issue and alleging infringement of a third, recently issued U.S. patent: U.S. Patent No. 7,188,180 B2, entitled “Method for Establishing Secure Communication Link Between Computers of Virtual Private Network.” We are seeking both damages, in an amount subject to proof at trial, and injunctive relief. Microsoft answered the amended complaint and asserted counterclaims against us on May 4, 2007. Microsoft counterclaimed for declarations that the three patents are not infringed, are invalid and are unenforceable. Microsoft seeks an award of its attorneys’ fees and costs. We filed a reply to Microsoft’s counterclaims on May 24, 2007. Discovery has begun, a Markman hearing on claim construction is scheduled for February 2009, and the trial is scheduled to begin on October 12, 2009. We have served our infringement contentions directed to certain of Microsoft’s operating system and unified messaging and collaboration applications. On March 31, 2008, Microsoft filed a Motion to Dismiss for lack of standing, which was denied by the court pursuant to an order dated June 3, 2008. Also pursuant to that court decision, on June 10, 2008, SAIC joined us in our lawsuit.
Because we have determined that Microsoft’s alleged unauthorized use of our patents would cause us severe economic harm and the failure to cause Microsoft to discontinue its use of such patents could result in the termination of our business, we have dedicated a significant portion of our economic resources, to date, to the prosecution of the Microsoft litigation and expect to continue to do so for the foreseeable future.
Although we believe Microsoft infringes three of our patents and we intend to vigorously prosecute this case, at this stage of the litigation the outcome cannot be predicted with any degree of reasonable certainty. Additionally, the Microsoft litigation will be costly and time-consuming, and we can provide no assurance that we will obtain a judgment against Microsoft for damages and/or injunctive relief. Should the District Court issue a judgment in favor of Microsoft, and in connection with such judgment determine that we had acted in bad faith or with fraudulent intent, or we were otherwise found to have exhibited inequitable conduct, the Court could award attorney fees to Microsoft, which would be payable by us.
In the near term, we will dedicate significant time and resources to the Microsoft litigation. The risks associated with such dedication of time and resources are set forth in theRisk Factorssection of this report.
One or more potential intellectual property infringement claims may also be available to us against certain other companies who have the resources to defend against any such claims. Although we believe these potential claims are worth pursuing, commencing a lawsuit can be expensive and time-consuming, and there is no assurance that we will prevail on such potential claims. In addition, bringing a lawsuit may lead to potential counterclaims which may preclude our ability to commercialize our initial products, which are currently in development.
Currently, we are not a party to any other pending legal proceedings, and are not awarenames of any proceeding threatened or contemplated against us by any governmental authorityunderwriters, dealers, agents or other party.

Research and Development
We are currentlyentities involved in basic research at our office located in Scotts Valley, California and through personnel based in Sterling, Virginia. We are focused on developing new techniques for automatic and transparent real-time communication security. We have invested approximately $56,000 in 2005, $554,187 in 2006, $684,316 in 2007 and $417,823 for the six-month period ended June 30, 2008 on research and development relating to our proposed products.
Additionally, we conduct some of our product development through the use of outsourced development partners. Our current development projects are derived from strategic relationships with other companies. We anticipate developing other new products through a combination of licensing, acquisitions and our discovery research activities.
Products in Development
We intend for our products to be available as object libraries for easy integration into enterprise VoIP, conference calling, IM, file transfer, application sharing, whiteboard, video conference and other real-time collaboration systems solutions.
We currently have two principal products in development:
• The VirnetX Edge Toolkit, which will be designed to allow OEM partners to integrate our proprietary technology into their private branch exchanges (better known as PBXs), call managers and client solutions. We anticipate releasing the first version of the Toolkit product in 2008.
• The VirnetX Secure Directory Service, which will be designed to provide secure presence and directory services to certified individual domain names based on identity verification and will be designed to enable automatic domain name system, or “DNS,” -triggered certified encrypted connections. We anticipate providing this service to initial customers in 2008.
We intend to commercialize our existing technology by designing, manufacturing and marketing products incorporating our technology and by partnering with other companies whose products incorporate our technology. In addition, we intend to leverage our outstanding team of scientists to continue to develop promising new technologies.
Government Regulation
The laws governing online secure communications remain largely unsettled, even in areas where there has been legislative action. It may take years to determine whether and how existing laws governing intellectual property, privacy and libel apply to online media. Such legislation may interfere with the growth in use of online secure communications and decrease the acceptance of online secure communications as a viable solution, which could adversely affect our business.
Due to the internet’s popularity and increasing use, new laws regulating secure communications may be adopted. These laws and regulations may cover, among other things, issues relating to privacy, pricing, taxation, telecommunications over the internet, content, copyrights, distribution and quality of products and services. We intend to comply with all new laws and regulations as they are adopted.
Employees
As of August 31, 2008 we had twelve full-time employees.
Facilities
Our principal executive offices are located at 5615 Scotts Valley Drive, Suite 110, Scotts Valley, California 95066. Between July 1, 2008 and August 31, 2009, we will lease this property for approximately $3,150 per month. We have no other properties.

EXECUTIVE COMPENSATION
COMPENSATION DISCUSSION AND ANALYSIS
Objectives and Philosophy of Executive Compensation
We maintain a peer-based executive compensation program comprised of multiple elements. We conducted our benchmarking analysis by evaluating:
• early and late stage private companies using a semi-annual survey of private, venture-backed companies that have received at least one (1) round of financing from a professionalU.S.-based venture capital firm. This semi-annual survey was prepared by CompensationPro (a Dow Jones company). Of the companies in this survey, over one-half are in the information technology business and the remainder are divided between healthcare, products and services and other companies;
• a key comparable company, Medivation, Inc., which also completed a reverse merger followed by an underwritten direct primary public offering. This company had similar market capitalization compared to us and was similarly early stage and pre-revenue at the time of their reverse merger, although this company is a medical device company; and
• public company peers using data we gathered from the SEC filings of ten (10) public companies with the same industry code as us and otherwise in a comparable industry, having a market capitalization of between $25 million and $500 million, and in a similar geographic region.
The primary objectives of our peer-based executive compensation program are:
• attracting and retaining the most talented and dedicated executives possible;
• correlating annual and long-term cash and stock incentives to achievement of measurable performance objectives; and
• aligning executives’ incentives with stockholder value creation.
To achieve these objectives, we implement and maintain compensation plans that tie a substantial portion of each executive’s overall compensation to key strategic financial and operational goals such as the establishment and maintenance of key strategic relationships, the development of our product candidates, the identification and advancement of additional product candidates, and the performance of our common stock price. Our compensation committee’s approach emphasizes the setting of compensation at levels the committee believes are competitive with executives in other companies of similar size and stage of development operating in the information technology industry while taking into account our relative performance and our own strategic goals.
Tax Deductibility of Executive Compensation
Our compensation committee and our Board have considered the potential future effects of Section 162(m) of the Internal Revenue Code on the compensation paid to our executive officers. Section 162(m) disallows a tax deduction for any publicly held corporation for individual compensation exceeding $1.0 million in any taxable year for any of our executive officers, unless compensation is performance based. In approving the amount and form of compensation for our executive officers, our compensation committee will continue to consider all elements of the cost to us of providing such compensation, including the potential impact of Section 162(m).
Role of Executive Officers
Our compensation committee exclusively makes all compensation decisions with regard to our chief executive officer and it approves recommendations regarding compensation for our other employees. Our president and chief executive officer generally attends compensation committee meetings and sometimes makes recommendations to our compensation committee regarding the amount and form of the compensation of the other executive officers and key employees. He is not present for any of the executive sessions or for any discussion of his own compensation.


29


Elements of Executive Compensation
Executive compensation consists of the following elements:
• Base Salary.  Base salaries for our executives are established based on the scope of their responsibilities, taking into account competitive market compensation paid by other companies for similar positions. Generally, the program is designed to deliver executive base salaries within the range of salaries for executives with the requisite skills in similar positions with similar responsibilities at comparable companies, in line with our compensation philosophy. Executives with more experience, critical skills,and/or considered key performers may be compensated above the range as part of our strategy for attracting, motivating and retaining highly experienced and high performing employees. Base salaries are reviewed annually and adjusted from time to time to realign salaries with market levels after taking into account individual responsibilities, performance, and experience. This review occurs each year in the fourth quarter and adjustments are made from time to time to ensure market competitiveness.
• Discretionary Annual Incentive Bonus.  Each year, our compensation committee establishes a target discretionary annual incentive bonus pool based on a percentage of an executive’s base salary and the achievement of corporate and individual objectives. Our compensation committee has the sole authority to award discretionary annual incentive bonuses to our chief executive officer and has authority along with our Board to award discretionary annual incentive bonuses to other employees. Our compensation committee utilizes annual incentive bonuses to compensate officers for achieving financial and operational goals and for achieving individual annual performance objectives. These objectives vary depending on the individual executive, but relate generally to strategic factors such as establishment and maintenance of key strategic relationships, development and implementation of our licensing strategy, development of our product, identification and advancement of additional products, and to financial factors such as raising capital, improving our results of operations, and increasing the price per share of our common stock.
• Long-Term Incentive Program.  We believe that long-term performance is achieved through an ownership culture that encourages high performance by our executive officers through the use of stock and stock-based awards. Our 2007 Stock Plan was established to provide our employees, including our executive officers, with incentives to help align those employees’ interests with the interests of stockholders. Our compensation committee believes that the use of stock and stock-based awards offers the best approach to achieving our compensation goals. We have historically elected to use stock options as the primary long-term equity incentive vehicle.
• Stock Option Grants.  Stock option grants are made at the commencement of employment, may be made annually based upon performance and, occasionally, following a significant change in job responsibilities or to meet other special retention objectives. Our compensation committee reviews and approves stock option awards to executive officers based upon a review of competitive compensation data, its assessment of individual performance, a review of each executive’s existing long-term incentives, and retention considerations. In determining the number of stock options to be granted to executives, we take into account the individual’s position, scope of responsibility, ability to affect profits and stockholder value, the individual’s historic and recent performance, and the value of stock options in relation to other elements of the individual executive’s total compensation. We expect to continue to use stock options as a long-term incentive vehicle because:
• stock options align the interests of executives with those of the stockholders, support a pay-for-performance culture, foster employee stock ownership, and focus the management team on increasing value for the stockholders;
• stock options are performance based and all the value received by the recipient of a stock option is based on the growth of the stock price;
• stock options help to provide a balance to the overall executive compensation program as base salary and our discretionary annual bonus program focus on short-term compensation, while the vesting of stock options increases stockholder value over the longer term; and
• the vesting period of stock options encourages executive retention and the preservation of stockholder value.


30


Stock Ownership Guidelines
We have not adopted stock ownership guidelines and our 2007 Stock Plan has provided the principal method for our executive officers to acquire equity in the Company. We currently do not require our directors or executive officers to own a particular amount of our common stock. Our compensation committee is satisfied that stock and option holdings among our directors and executive officers are sufficient at this time to provide motivation and to align this group’s interests with those of our stockholders.
Perquisites
Our executive officers participate in the same group insurance and employee benefit plans as our other salaried employees. At this time we do not provide special benefits or other perquisites to our executive officers.
Change of Control Arrangements
Our 2007 Stock Plan allows our Board to determine the terms and condition of awards issued thereunder. Our Board has made the determination that all options issued under our 2007 Stock Plan will include the provision that in the event of a “Change of Control” (as defined in our 2007 Stock Plan), all unvested shares underlying the option will vest and become exercisable immediately prior to the consummation of such Change of Control transaction.
Named Executive Officers’ Compensation
Base Salary
Mr. Larsen is our president and chief executive officer, as well as a director. Relative to the benchmarking surveys described above, his base salary is above the 75th percentile for early and late stage private companies, below our key comparable company and between the median and the 75th percentile of our public company peers. Mr. Larsen, a founder of VirnetX, Inc., has driven the organization’s performance, leading it from inception, through the earlystart-up phase and through several rounds of financing. Mr. Larsen will be critical to our ability to pursue our licensing strategy going forward. On December 31, 2007, in an executive session including only the independent directors, our compensation committee assessed Mr. Larsen’s 2007 performance, considering our and Mr. Larsen’s accomplishments and the committee’s own subjective assessment of his performance.
Mr. Sliney is our chief financial officer and his base salary is below the median of early stage private companies, below the median for late stage private companies and our public company peers, and below our key comparable company. In establishing Mr. Sliney’s base salary, our compensation committee primarily considered Mr. Sliney’s experience in public company work, his transactional and strategic skills, his level of responsibility, past contributions to our performance and expected contributions to our further success.
Discretionary Annual Incentive Bonus
Actual bonus awards for each Named Executive Officer are listed in “Executive Compensation — Summary Compensation Table” on page 32 of this report. On December 31, 2007, after assessing performance and after taking into account the fact that no bonuses had been paid to our executive officers to date, our compensation committee awarded discretionary annual bonuses to Mr. Larsen and Mr. Sliney.
Long-Term Incentive Program
In determining the amount of the stock option grants made to Mr. Larsen and to Mr. Sliney in 2007, our compensation committee evaluated data derived from the same benchmarking analysis described above that was used to establish cash compensation amounts.
In 2007, Mr. Larsen was granted a number of options such that the aggregate of all of his equity incentive shares outstanding under our 2007 Stock Plan represents a fully diluted percentage ownership of the Company that was below the median for early stage private companies, and between the median and the 75th percentile for late stage private companies. In addition, the Black-Scholes option value of all of his equity incentive shares outstanding


31


under our 2007 Stock Plan is higher than our key comparable company and between the median and 75th percentile of our public company peers.
In 2007, Mr. Sliney was granted a number of options such that the aggregate of all of his equity incentive shares outstanding under our 2007 Stock Plan represents a fully diluted percentage ownership of the Company that was below the median for early stage private companies, and at the median for late stage private companies. In addition, the Black-Scholes option value of all of his equity incentive shares outstanding under our 2007 Stock Plan is below our key comparable company and between the median and 75th percentile of our public company peers.

Transactions with Related Persons
Our Code of Ethics requires each of our directors, employees, officers, and consultants to disclose any significant interest in any related party transaction and that interest must be approved in writing by our legal

department. If it is determined that the transaction is required to be reported under SEC rules, then the transaction will be subject to the review and approval by our audit committee of our Board. A copy of our Code of Ethics is available on our website athttp://www.virnetx.com/in the “Corporate Governance” link under the “Investors” tab.
The charter of our audit committee affirms that one of our audit committee’s responsibilities is to review and approve material related party transactions and related party transactions that are required to be disclosed in our public filings. We annually require each of our directors and executive officers to complete a directors’ and officers’ questionnaire that elicits information about related party transactions as such term is defined by SEC rules and regulations. These procedures are intended to determine whether any such related party transaction impairs the independence of a director or presents a conflict of interest on the part of a director, employee, or officer.
The following is a description of each transaction in the last fiscal year and each currently proposed transaction in which:
• we have been or are to be a participant;
• the amount involved exceeds $120,000; and
• any of our directors, executive officers, holders of more than 5% of our capital stock, or any immediate family member of, or person sharing the household with, any of these individuals, had or will have a direct or indirect material interest.
Stock Option Grants
We have granted stock options to our executive officers and certain of our directors under our 2007 Stock Plan.
In connection with the consummation of the merger between VirnetX Holding Corporation and VirnetX, we assumed certain obligations under an Advisory Service Agreement dated November 6, 2006 by and between VirnetX and MDB Capital Group LLC, as amended by the terms of that certain Release Agreement between the same parties, which was executed on July 5, 2007. MDB Capital Group was a stockholder of VirnetX prior to the merger and Christopher Marlett, a principal at MDB Capital Group, is currently one of our stockholders as a result of the merger. Christopher Marlett, as of July 5, 2007, beneficially owned approximately 6.7% of our issued and outstanding shares of common stock. MDB Capital Group’s affiliates include Anthony DiGiandomenico and Robert Levande, each of whom is one of our existing stockholders as a result of the merger.
Additionally, in connection with the consummation of the merger, we entered into the following agreements and transactions with certain of our directors, executive officers and 5% stockholders:
Indemnification Agreements
We entered into Indemnification Agreements with each person who became one of VirnetX Holding Corporation’s directors or officers in connection with the consummation of the merger, pursuant to which, among other things, we will indemnify such directors and officers to the fullest extent permitted by Delaware law, and provide for advancement of legal expenses under certain circumstances.
Registration Rights Agreement
Effective as of July 5, 2007, we entered into a Registration Rights Agreement with all of the persons who were issued shares of our common stock and securities convertible into shares of our common stock in the merger.
Pursuant to the Registration Rights Agreement, commencing six months after the closing of the merger, the securityholders have a right to request that we register for resale (a) the shares of common stock issued to such persons in the merger and (b) the shares of common stock underlying convertible notes, options and warrants issued to such persons in the merger. We are required to cause each such registration statement filed as a result of such requests to be declared effective under the Securities Act as promptly as possible after the filing thereof and to keep such registration statement continuously effective under the Securities Act until the earlier of (i) the date when all shares included in the registration statement have been sold; (ii) the date that all shares can be sold pursuant to Rule 144; and (iii) one year from the effective date of such registration statement.


34


Additionally, the Registration Rights Agreement provides the securityholders with “piggyback” registration rights such that at any time there is not an effective registration statement covering the common stock described above and we file a registration statement relating to an offering for our own account or the account of others under the Securities Act, other than in connection with any acquisition of any entity or business or equity securities issuable in connection with stock options or other employee benefit plans and other than in connection with this offering, then we are required to send notice to the securityholders of such intended filing at least 20 days prior to filing such registration statement and we are required to automatically include in such registration statement all shares of common stock issued in the merger and all shares of common stock underlying convertible notes, options and warrants issued in the merger.
Each securityholder also has indemnified us, our directors, officers, agents, and certain other control persons against damages arising out of or based upon: (i) such securityholder’s failure to comply with the prospectus delivery requirements of the Securities Act or (ii) such securityholder’s provision of any untrue or alleged untrue statement of a material fact to be contained in any registration statement or prospectus, or arising out of or relating to any such securityholder’s omission or alleged omission of a material fact required to be stated therein or necessary to make the statements contained in such registration statement or prospectus not misleading.
Lock-Up Agreements
Effective as of July 5, 2007, we entered into aLock-Up Agreement with certain of the persons who were issued shares of our common stock in the merger and all persons who exchanged VirnetX options for VirnetX Holding Corporation options in the merger, pursuant to which we imposed certain restrictions on the sale of our common stocksecurities described in that prospectus supplement and any applicable fee, commission or any securities convertible into or which may be exercised to purchase any shares of our common stock acquired in connectiondiscount arrangement with the merger for a period of at least 12 months after the consummation of the merger; provided that the lockup period may be extended under certain circumstances. In addition, all of our officers and directors, as well as those stockholders listed in the resale prospectus filed with this registration statement have entered into aLock-Up Agreement with the underwriter for a period commencing on the date hereof and ending 12 months from the effective date of the registration statement; provided, however, that if the average closing price per share of the Company’s common stock exceeds 150% of the public offering price of the shares to be offered for 15 consecutive trading days during thelock-up period, the shares of common stock held by the San Gabriel group of investors shall be released from thelock-up by our underwriter. During the first quarter of 2008 the market price early release provision was triggered such that all 5,333,333 shares of our common stock held by the San Gabriel group of investors covered by this prospectus are now no longer subject to the transfer restrictions of the underwriter’s lockup agreement.them.

PLAN OF DISTRIBUTION
The Selling Stockholders and any of their pledgees, assignees and successors-in interest may, from time to time, sell any or all of their shares of Common Stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These sales may be at fixed or negotiated prices. The Selling Stockholders may use any one or more of the following methods when selling shares:
• ordinary brokerage transactions and transactions in which the broker/dealer solicits purchasers;
• block trades in which the broker/dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;
• purchases by a broker/dealer as principal and resale by the broker/dealer for its account;
• an exchange distribution in accordance with the Rules of the applicable exchange;
• privately negotiated transactions;
• settlement of short sales;
• broker/dealers may agree with the Selling Stockholders to sell a specified number of such shares at a stipulated price per share;
• a combination of any such methods of sale; and
• any other method permitted pursuant to applicable law.
The Selling Stockholders may also sell shares under Rule 144 under the Securities Act, if available, rather than under this prospectus.
Broker/dealers engaged by the Selling Stockholders may arrange for other brokers/dealers to participate in sales. Broker/dealers may receive commissions from the Selling Stockholders (or, if any broker/dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated. The Selling Stockholders do not expect these commissions to exceed what is customary in the types of transactions involved.
The Selling Stockholders may from time to time pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock from time to time under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act of 1933 amending the list of Selling Stockholders to include the pledgee, transferee or other successors in interest as Selling Stockholders under this prospectus.
The Selling Stockholders and any broker/dealers or agents that are involved in selling the shares may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker/dealers or agents and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions under the Securities Act. The Selling Stockholders have informed VirnetX Holding Corporation that it does not have any agreement or understanding, directly or indirectly, with any person to distribute the Common Stock. Upon being advised of any underwriting arrangements that may be entered into by a Selling Stockholder after the date of this prospectus, the Company will prepare a supplement to this prospectus to disclose those arrangements. We anticipate that the selling price for the common stock and warrants will be at or between the “bid” and “asked” prices for these securities, as quoted in the over-the-counter market immediately preceding the sale.
The Company is required to pay all fees and expenses incident to the registration of the shares. The Company has agreed to indemnify the Selling Stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.


44


To the extent that the Selling Stockholders intend to sell their securities directly, through agents, dealers, or through Gilford Securities Incorporated, in the over-the-counter market or otherwise, on terms and conditions that they determine at the time of the sale or that they determine in private negotiations between buyer and seller, their sales of the shares of common stock may be made in accordance with this prospectus and under the provisions of Rule 144 adopted under the Securities Act.

Anti-Takeover Effects of Some Provisions of Delaware Law

Provisions of Delaware law and our Amended and Restated Certificate of Incorporation and Bylaws could make the acquisition of our company through tender offer, a proxy context or other means more difficult and could make the removal of incumbent officers and directors more difficult. We expect these provisions to discourage coercive takeover practices and inadequate takeover bids and to encourage persons seeking to acquire control of our company to first negotiate with our board of directors. We believe that the benefits provided by our ability to negotiate with the proponent of an unfriendly or unsolicited proposal outweigh the disadvantages of discouraging these proposals. We believe the negotiation of an unfriendly or unsolicited proposal could result in an improvement of its terms.

Amended and Restated Certificate of Incorporation and Bylaws

Our Amended and Restated Certificate of Incorporation and our Bylaws provide for the following:
·
• A staggered BoardUndesignated Preferred Stock.  The ability to authorize undesignated preferred stock makes it possible for our board of Directors:  this means that onlydirectors to issue one or two directors (since wemore series of preferred stock with voting or other rights or preferences that could impede the success of any attempt to change control of VirnetX. These and other provisions may have afive-person Board of Directors) will be up for election at any given annual meeting. This has the effect of deferring hostile takeovers or delaying the abilitychanges in control or management of our company.
·Stockholder Meetings.  Our charter documents provide that a special meeting of stockholders may be called only by resolution adopted by the board of directors.
·Requirements for Advance Notification of Stockholder Nominations and Proposals.  Our Bylaws establish advance notice procedures with respect to effectstockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of the board of directors or a changecommittee of the board of directors.
·Board Classification.  Our board of directors is divided into three classes. The directors in each class will serve for a three-year term, one class being elected each year by our stockholders. This system of electing and removing directors may tend to discourage a third party from making a tender offer or otherwise attempting to obtain control of the Board of Directors sinceus, because it will take two annual meetingsgenerally makes it more difficult for stockholders to effectively replace at least three directors which represents a majority of the Boarddirectors.
·Limits on Ability of Directors.
• Blank check preferred stock:  our Board of Directors has the authorityStockholders to establish the rights, preferences and privileges of our 10,000,000 authorized but unissued shares of preferred stock. Therefore, this stock may be issued at the discretion of our Board of Directors with preferences over your shares of common stock in a manner that is materially dilutive to existing stockholders. In addition, blank check preferred stock can be used to create a “poison pill” which is designed to deter a hostile bidder from buying a controlling interestAct by Written Consent.  We have provided in our stock without the approvalcertificate of incorporation that our Board of Directors. We havestockholders may not adopted such a “poison pill,” but our Board of Directors will have the ability to do so in the future very rapidly and without stockholder approval.
• Advance notice requirements for director nominations and for new business to be brought up at stockholder meetings:  stockholders wishing to submit director nominations or raise matters to a vote of the stockholders must provide notice to us within very specific date windows in order to have the matter voted on at the meeting. This has the effect of giving our Board of Directors and management more time to react to stockholder proposals generally and could also have the effect of delaying a stockholder proposal to a subsequent meeting to the extent such proposal is not raised in a timely manner for an upcoming meeting.
• Elimination of stockholder actionsact by written consent:  this has the effect of eliminatingconsent. This limit on the ability of our stockholders to act by written consent may lengthen the amount of time required to take stockholder actions. As a stockholder orresult, a group of stockholders representingholder controlling a majority of our capital stock would not be able to amend our Bylaws or remove directors without holding a meeting of our stockholders called in accordance with our Bylaws.
·Amendment of Bylaws.  Any amendment of our Bylaws requires approval by holders of at least two-thirds of our outstanding capital stock entitled to vote generally in the outstanding shares to take actions rapidly and without prior notice to our Boardelection of Directors and management ordirectors.

Delaware Anti-Takeover Statute
We are subject to Section 203 of the Delaware General Corporation Law, an anti-takeover law. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years following the date the person became an interested stockholder, unless:
·prior to the minority stockholders. Along withdate of the advance notice requirements described above, this provisiontransaction, the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;
-11-

·the stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares outstanding (a) shares owned by persons who are directors and also gives our Board of Directorsofficers, and management more time(b) shares owned by employee stock plans in which employee participants do not have the right to react to proposed stockholder actions.
• Super majority requirement for stockholder amendmentsdetermine confidentially whether shares held subject to the By-laws:  our By-laws mayplan will be alteredtendered in a tender or amendedexchange offer; or new By-laws adopted
·on or subsequent to the date of the transaction, the business combination is approved by the board and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 662/3%two-thirds of the outstanding shares. This has the effect of requiring a substantially greater vote of the stockholders to approve any changes to our By-laws.
• Elimination of the ability of stockholders to call a special meeting of the stockholders:  only the Board of Directors or management can call special meetings of the stockholders. This could meanvoting stock that stockholders, even those who represent a significant block of shares, may need to wait for the annual meeting before nominating directors or raising other business proposals to be voted onis not owned by the stockholders.interested stockholder.
 
Transfer AgentGenerally, a “business combination” includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. An “interested stockholder” is a person who, together with affiliates and Registrarassociates, owns or, within three years prior to the determination of interested stockholder status, did own 15% or more of a corporation’s outstanding voting securities. We expect the existence of this provision to have an anti-takeover effect with respect to transactions our board of directors does not approve in advance. We also anticipate that Section 203 may also discourage attempts that might result in a premium over the market price for the shares of common stock held by stockholders.

DESCRIPTION OF THE DEPOSITARY SHARES
General
At our option, we may elect to offer fractional shares of preferred stock, rather than full shares of preferred stock.  If we do elect to offer fractional shares of preferred stock, we will issue receipts for depositary shares and each of these depositary shares will represent a fraction of a share of a particular series of preferred stock, as specified in the applicable prospectus supplement.  Each owner of a depositary share will be entitled, in proportion to the applicable fractional interest in shares of preferred stock underlying that depositary share, to all rights and preferences of the preferred stock underlying that depositary share.  These rights may include dividend, voting, redemption and liquidation rights.
 
The shares of preferred stock underlying the depositary shares will be deposited with a bank or trust company selected by us to act as depositary, under a deposit agreement by and among us, the depositary and the holders of the depositary receipts.  The depositary will be the transfer agent, registrar and registrardividend disbursing agent for the depositary shares.
The depositary shares will be evidenced by depositary receipts issued pursuant to the depositary agreement.  Holders of depositary receipts agree to be bound by the deposit agreement, which requires holders to take certain actions such as filing proof of residence and paying certain charges.
The summary of terms of the depositary shares contained in this prospectus is not complete, and is subject to modification in any prospectus supplement for any issuance of depositary shares.  You should refer to the forms of the deposit agreement, our certificate of incorporation and the certificate of designation that are, or will be, filed with the Commission for the applicable series of preferred stock.
Dividends
The depositary will distribute cash dividends or other cash distributions, if any, received in respect of the series of preferred stock underlying the depositary shares to the record holders of depositary receipts in proportion to the number of depositary shares owned by those holders on the relevant record date.  The relevant record date for depositary shares will be the same date as the record date for the preferred stock.
In the event of a distribution other than in cash, the depositary will distribute property received by it to the record holders of depositary receipts that are entitled to receive the distribution, unless the depositary determines that it is not feasible to make the distribution.  If this occurs, the depositary, with our approval, may adopt another method for the distribution, including selling the property and distributing the net proceeds to the holders.
Liquidation preference
If a series of preferred stock underlying the depositary shares has a liquidation preference, in the event of our voluntary or involuntary liquidation, dissolution or winding up, holders of depositary shares will be entitled to receive the fraction of the liquidation preference accorded each share of the applicable series of preferred stock, as set forth in the applicable prospectus supplement.
Redemption
If a series of preferred stock underlying the depositary shares is subject to redemption, the depositary shares will be redeemed from the proceeds received by the depositary resulting from the redemption, in whole or in part, of the preferred stock held by the depositary.  Whenever we redeem any preferred stock held by the depositary, the depositary will redeem, as of the same redemption date, the number of depositary shares representing the preferred stock so redeemed.  The depositary will mail the notice of redemption to the record holders of the depositary receipts promptly upon receiving the notice from us and not fewer than 20 or more than 60 days, unless otherwise provided in the applicable prospectus supplement, prior to the date fixed for redemption of the preferred stock.
-13-

Voting
Upon receipt of notice of any meeting at which the holders of preferred stock are entitled to vote, the depositary will mail the information contained in the notice of meeting to the record holders of the depositary receipts underlying the preferred stock.  Each record holder of those depositary receipts on the record date will be entitled to instruct the depositary as to the exercise of the voting rights pertaining to the amount of preferred stock underlying that holder’s depositary shares.  The record date for the depositary will be the same date as the record date for the preferred stock.  The depositary will, to the extent practicable, vote the preferred stock underlying the depositary shares in accordance with these instructions.  We will agree to take all action that may be deemed necessary by the depositary in order to enable the depositary to vote the preferred stock in accordance with these instructions.  The depositary will not vote the preferred stock to the extent that it does not receive specific instructions from the holders of depositary receipts.
Withdrawal of preferred stock
Owners of depositary shares will be entitled to receive upon surrender of depositary receipts at the principal office of the depositary and payment of any unpaid amount due to the depositary, the number of whole shares of preferred stock underlying their depositary shares.
Partial shares of preferred stock will not be issued.  Holders of preferred stock will not be entitled to deposit the shares under the deposit agreement or to receive depositary receipts evidencing depositary shares for the preferred stock.
Amendment and termination of the deposit agreement
The form of depositary receipt evidencing the depositary shares and any provision of the deposit agreement may be amended by agreement between the depositary and us.  However, any amendment which materially and adversely alters the rights of the holders of depositary shares, other than fee changes, will not be effective unless the amendment has been approved by at least a majority of the outstanding depositary shares.  The deposit agreement may be terminated by the depositary or us only if:
·all outstanding depositary shares have been redeemed; or
·there has been a final distribution of the preferred stock in connection with our dissolution and such distribution has been made to all the holders of depositary shares.
Charges of depositary
We will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangement.  We will also pay charges of the depositary in connection with:
·the initial deposit of the preferred stock;
·the initial issuance of the depositary shares;
·any redemption of the preferred stock; and
·all withdrawals of preferred stock by owners of depositary shares.
-14-

Holders of depositary receipts will pay transfer, income and other taxes and governmental charges and other specified charges as provided in the deposit agreement for their accounts.  If these charges have not been paid, the depositary may:
·refuse to transfer depositary shares;
·withhold dividends and distributions; and
·sell the depositary shares evidenced by the depositary receipt.
Miscellaneous
The depositary will forward to the holders of depositary receipts all reports and communications we deliver to the depositary that we are required to furnish to the holders of the preferred stock.  In addition, the depositary will make available for inspection by holders of depositary receipts at the principal office of the depositary, and at such other places as it may from time to time deem advisable, any reports and communications we deliver to the depositary as the holder of preferred stock.
Neither the depositary nor we will be liable if either the depositary or we are prevented or delayed by law or any circumstance beyond the control of either the depositary or us in performing our respective obligations under the deposit agreement.  Our obligations and the depositary’s obligations will be limited to the performance in good faith of our or the depositary’s respective duties under the deposit agreement.  Neither the depositary nor we will be obligated to prosecute or defend any legal proceeding in respect of any depositary shares or preferred stock unless satisfactory indemnity is furnished.  The depositary and we may rely on:
·written advice of counsel or accountants;
·information provided by holders of depositary receipts or other persons believed in good faith to be competent to give such information; and
·documents believed to be genuine and to have been signed or presented by the proper party or parties.
Resignation and removal of depositary
The depositary may resign at any time by delivering a notice to us.  We may remove the depositary at any time.  Any such resignation or removal will take effect upon the appointment of a successor depositary and its acceptance of such appointment.  The successor depositary must be appointed within 60 days after delivery of the notice for resignation or removal.  The successor depositary must be a bank and trust company having its principal office in the United States of America and having a combined capital and surplus of at least $50,000,000.
Federal income tax consequences
Owners of the depositary shares will be treated for U.S. federal income tax purposes as if they were owners of the preferred stock underlying the depositary shares.  As a result, owners will be entitled to take into account for U.S. federal income tax purposes and deductions to which they would be entitled if they were holders of such preferred stock.  No gain or loss will be recognized for U.S. federal income tax purposes upon the withdrawal of preferred stock in exchange for depositary shares.  The tax basis of each share of preferred stock to an exchanging owner of depositary shares will, upon such exchange, be the same as the aggregate tax basis of the depositary shares exchanged.  The holding period for preferred stock in the hands of an exchanging owner of depositary shares will include the period during which such person owned such depositary shares.

·if the principal amount payable at stated maturity will not be determinable as of any date prior to stated maturity, the amount or method for determining the amount which will be deemed to be the principal amount;
·if applicable, whether the debt securities shall be subject to the defeasance provisions described below under “Satisfaction and discharge; defeasance” or such other defeasance provisions specified in the applicable prospectus supplement for the debt securities;
·any conversion or exchange provisions;
·whether the debt securities will be issuable in the form of a global security;

·with respect to the debt securities that do not bear interest, the dates for certain required reports to the applicable trustee;
·any and all additional, eliminated or changed terms that will apply to the debt securities; and
20

·any other terms of such debt securities.
Unless otherwise specified in the prospectus supplement, the debt securities will be registered debt securities.  Debt securities may be sold at a substantial discount below their stated principal amount, bearing no interest or interest at a rate which at time of issuance is below market rates.  The U.S. federal income tax considerations applicable to debt securities sold at a discount will be described in the applicable prospectus supplement.
Exchange and transfer
Debt securities may be transferred or exchanged at the office of the security registrar or at the office of any transfer agent designated by us.
We will not impose a service charge for any transfer or exchange, but we may require holders to pay any tax or other governmental charges associated with any transfer or exchange.
In the event of any partial redemption of debt securities of any series, we will not be required to:
·issue, register the transfer of, or exchange, any debt security of that series during a period beginning at the opening of business 15 days before the day of mailing of a notice of redemption and ending at the close of business on the day of the mailing; or
·register the transfer of or exchange any debt security of that series selected for redemption, in whole or in part, except the unredeemed portion being redeemed in part.
We will appoint the trustee as the initial security registrar.  Any transfer agent, in addition to the security registrar initially designated by us, will be named in the prospectus supplement.  We may designate additional transfer agents or change transfer agents or change the office of the transfer agent.  However, we will be required to maintain a transfer agent in each place of payment for the debt securities of each series.
Global securities
The debt securities of any series may be represented, in whole or in part, by one or more global securities.  Each global security will:
·be registered in the name of a depositary, or its nominee, that we will identify in a prospectus supplement;
·be deposited with the depositary or nominee or custodian; and
·bear any required legends.
No global security may be exchanged in whole or in part for debt securities registered in the name of any person other than the depositary or any nominee unless:
·the depositary has notified us that it is unwilling or unable to continue as depositary or has ceased to be qualified to act as depositary;
·an event of default is continuing with respect to the debt securities of the applicable series; or
·any other circumstance described in a prospectus supplement has occurred permitting or requiring the issuance of any such security.
21

As long as the depositary, or its nominee, is the registered owner of a global security, the depositary or nominee will be considered the sole owner and holder of the debt securities represented by the global security for all purposes under the indentures.  Except in the above limited circumstances, owners of beneficial interests in a global security will not be:
·entitled to have the debt securities registered in their names;
·entitled to physical delivery of certificated debt securities; or
·considered to be holders of those debt securities under the indenture.
Payments on a global security will be made to the depositary or its nominee as the holder of the global security.  Some jurisdictions have laws that require that certain purchasers of securities take physical delivery of such securities in definitive form.  These laws may impair the ability to transfer beneficial interests in a global security.
Institutions that have accounts with the depositary or its nominee are referred to as “participants.”  Ownership of beneficial interests in a global security will be limited to participants and to persons that may hold beneficial interests through participants.  The depositary will credit, on its book-entry registration and transfer system, the respective principal amounts of debt securities represented by the global security to the accounts of its participants.
Ownership of beneficial interests in a global security will be shown on and effected through records maintained by the depositary, with respect to participants’ interests, or any participant, with respect to interests of persons held by participants on their behalf.
Payments, transfers and exchanges relating to beneficial interests in a global security will be subject to policies and procedures of the depositary.  The depositary policies and procedures may change from time to time.  Neither any trustee nor we will have any responsibility or liability for the depositary’s or any participant’s records with respect to beneficial interests in a global security.
Payment and paying agents
Unless otherwise indicated in a prospectus supplement, the provisions described in this paragraph will apply to the debt securities.  Payment of interest on a debt security on any interest payment date will be made to the person in whose name the debt security is registered at the close of business on the regular record date.  Payment on debt securities of a particular series will be payable at the office of a paying agent or paying agents designated by us.  However, at our option, we may pay interest by mailing a check to the record holder.  The trustee will be designated as our initial paying agent.
We may also name any other paying agents in a prospectus supplement.  We may designate additional paying agents, change paying agents or change the office of any paying agent.  However, we will be required to maintain a paying agent in each place of payment for the debt securities of a particular series.
All moneys paid by us to a paying agent for payment on any debt security that remain unclaimed for a period ending the earlier of:
·10 business days prior to the date the money would be turned over to the applicable state; or
·at the end of two years after such payment was due,
will be repaid to us thereafter.  The holder may look only to us for such payment.
22

No protection in the event of a change of control
Unless otherwise indicated in a prospectus supplement with respect to a particular series of debt securities, the debt securities will not contain any provisions that may afford holders of the debt securities protection in the event we have a change in control or in the event of a highly leveraged transaction, whether or not such transaction results in a change in control.
Covenants
Unless otherwise indicated in a prospectus supplement with respect to a particular series of debt securities, the debt securities will not contain any financial or restrictive covenants.
Consolidation, merger and sale of assets
Unless we indicate otherwise in a prospectus supplement with respect to a particular series of debt securities, we may not consolidate with or merge into any other person (other than one of our subsidiaries), in a transaction in which we are not the surviving corporation, or convey, transfer or lease our properties and assets substantially as an entirety to, any person (other one of our subsidiaries), unless:
·the successor entity, if any, is a U.S. corporation, limited liability company, partnership, trust or other business entity;
·the successor entity assumes our obligations on the debt securities and under the indentures;
·immediately after giving effect to the transaction, no default or event of default shall have occurred and be continuing; and
·certain other conditions specified in the indenture are met.
Events of default
Unless we indicate otherwise in a prospectus supplement, the following will be events of default for any series of debt securities under the indentures:
(1)we fail to pay principal of or any premium on any debt security of that series when due;
(2)we fail to pay any interest on any debt security of that series for 30 days after it becomes due;
(3)we fail to deposit any sinking fund payment when due;
(4)we fail to perform any other covenant in the indenture and such failure continues for 90 days after we are given the notice required in the indentures; and
(5)certain events involving our bankruptcy, insolvency or reorganization.
Additional or different events of default applicable to a series of debt securities may be described in a prospectus supplement.  An event of default of one series of debt securities is not necessarily an event of default for any other series of debt securities.
The trustee may withhold notice to the holders of any default, except defaults in the payment of principal, premium, if any, interest, any sinking fund installment on, or with respect to any conversion right of, the debt securities of such series.  However, the trustee must consider it to be in the interest of the holders of the debt securities of such series to withhold this notice.
23

Unless we indicate otherwise in a prospectus supplement, if an event of default, other than an event of default described in clause (5) above, shall occur and be continuing with respect to any series of debt securities, either the trustee or the holders of at least 25 percent in aggregate principal amount of the outstanding securities of that series may declare the principal amount and premium, if any, of the debt securities of that series, or if any debt securities of that series are original issue discount securities, such other amount as may be specified in the applicable prospectus supplement, in each case together with accrued and unpaid interest, if any, thereon, to be due and payable immediately.
Unless we indicate otherwise in a prospectus supplement, if an event of default described in clause (5) above shall occur, the principal amount and premium, if any, of all the debt securities of that series, or if any debt securities of that series are original issue discount securities, such other amount as may be specified in the applicable prospectus supplement, in each case together with accrued and unpaid interest, if any, thereon, will automatically become immediately due and payable.  Any payment by us on the subordinated debt securities following any such acceleration will be subject to the subordination provisions described below under “Subordinated debt securities.”
Notwithstanding the foregoing, each indenture will provide that we may, at our option, elect that the sole remedy for an event of default relating to our failure to comply with our obligations described under the section entitled “Reports” below or our failure to comply with the requirements of Section 314(a)(1) of the Trust Indenture Act will for the first 360 days after the occurrence of such an event of default consist exclusively of the right to receive additional interest on the relevant series of debt securities at an annual rate equal to (i) 0.25% of the principal amount of such series of debt securities for the first 180 days after the occurrence of such event of default and (ii) 0.50% of the principal amount of such series of debt securities from the 181st day to, and including, the 360th day after the occurrence of such event of default, which we call “additional interest.”  If we so elect, the additional interest will accrue on all outstanding debt securities from and including the date on which such event of default first occurs until such violation is cured or waived and shall be payable on each relevant interest payment date to holders of record on the regular record date immediately preceding the interest payment date.  On the 361st day after such event of default (if such violation is not cured or waived prior to such 361st day), the debt securities will be subject to acceleration as provided above.  In the event we do not elect to pay additional interest upon any such event of default in accordance with this paragraph, the debt securities will be subject to acceleration as provided above.
In order to elect to pay the additional interest as the sole remedy during the first 360 days after the occurrence of any event of default relating to the failure to comply with the reporting obligations in accordance with the preceding paragraph, we must notify all holders of debt securities and the trustee and paying agent of such election prior to the close of business on the first business day following the date on which such event of default occurs.  Upon our failure to timely give such notice or pay the additional interest, the debt securities will be immediately subject to acceleration as provided above.
After acceleration, the holders of a majority in aggregate principal amount of the outstanding securities of that series may, under certain circumstances, rescind and annul such acceleration if all events of default, other than the non-payment of accelerated principal, or other specified amounts or interest, have been cured or waived.
Other than the duty to act with the required care during an event of default, the trustee will not be obligated to exercise any of its rights or powers at the request of the holders unless the holders shall have offered to the trustee reasonable indemnity.  Generally, the holders of a majority in aggregate principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee.
A holder of debt securities of any series will not have any right to institute any proceeding under the indentures, or for the appointment of a receiver or a trustee, or for any other remedy under the indentures, unless:
24

(1)the holder has previously given to the trustee written notice of a continuing event of default with respect to the debt securities of that series;
(2)the holders of at least 25 percent in aggregate principal amount of the outstanding debt securities of that series have made a written request and have offered reasonable indemnity to the trustee to institute the proceeding; and
(3)the trustee has failed to institute the proceeding and has not received direction inconsistent with the original request from the holders of a majority in aggregate principal amount of the outstanding debt securities of that series within 60 days after the original request.
Holders may, however, sue to enforce the payment of principal, premium or interest on any debt security on or after the due date or to enforce the right, if any, to convert any debt security (if the debt security is convertible) without following the procedures listed in (1) through (3) above.
We will furnish the trustee an annual statement from our officers as to whether or not we are in default in the performance of the conditions and covenants under the indenture and, if so, specifying all known defaults.
Modification and waiver
Unless we indicate otherwise in a prospectus supplement, the applicable trustee and we may make modifications and amendments to an indenture with the consent of the holders of a majority in aggregate principal amount of the outstanding securities of each series affected by the modification or amendment.
We may also make modifications and amendments to the indentures for the benefit of holders without their consent, for certain purposes including, but not limited to:
·to evidence the succession of another person to VirnetX, or successive successions, and the assumption by any such successor of the covenants of VirnetX in the indentures in compliance with Article 8 of the indentures;
·adding covenants;
·adding events of default;
·making certain changes to facilitate the issuance of the debt securities;
·to add to, change or eliminate any of the provisions of the indentures or more series of securities, provided that any such addition, change or elimination (A) shall neither (i) apply to any security of any series created prior to the execution of such supplemental indenture and entitled to the benefit of such provision nor (ii) modify the rights of the holder of any such security with respect to such provision or (B) shall become effective only when there is no such security outstanding;
·securing the debt securities;
·providing for guaranties of, or additional obligors on, the debt securities;
·to establish the form or term of debt securities as permitted by Sections 2.1 and 3.1 of the indenture;
·providing for a successor trustee or additional trustees;
25

·conforming the indenture to the description of the securities set forth in this prospectus or the accompanying prospectus supplement;
·curing any ambiguity, defect or inconsistency; provided that such action shall not adversely affect the interest of the holders in any material respect;
·permitting or facilitating the defeasance and discharge of the debt securities;
·make such other provisions in regard to matters or questions arising under the indentures or under any supplemental indentures as our board of directors may deem necessary or desirable, and which does not in each case adversely affect the interests of the holders of the debt securities of a series; and
·comply with requirements of the U.S. Securities and Exchange Commission in order to effect or maintain the qualifications of the indentures under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”).
However, neither the trustee nor we may make any modification or amendment without the consent of the holder of each outstanding security of that series affected by the modification or amendment if such modification or amendment would:
·change the stated maturity of the principal of, or any installment of principal or interest on, any debt security;
·reduce the principal, premium, if any, or interest on any debt security or any amount payable upon redemption or repurchase, whether at our option or the option of any holder, or reduce the amount of any sinking fund payments;
·reduce the principal of an original issue discount security or any other debt security payable on acceleration of maturity;
·change the place of payment or the currency in which any debt security is payable;
·impair the right to enforce any payment after the stated maturity or redemption date;
·if subordinated debt securities, modify the subordination provisions in a materially adverse manner to the holders;
·adversely affect the right to convert any debt security if the debt security is a convertible debt security; or
·change the provisions in the indenture that relate to modifying or amending the indenture.
Satisfaction and discharge; defeasance
We may be discharged from our obligations on the debt securities, subject to limited exceptions, of any series that have matured or will mature or be redeemed within one year if we deposit enough money with the trustee to pay all the principal, interest and any premium due to the stated maturity date or redemption date of the debt securities.
Each indenture contains a provision that permits us to elect either or both of the following:
·we may elect to be discharged from all of our obligations, subject to limited exceptions, with respect to any series of debt securities then outstanding.  If we make this election, the holders of the debt securities of the series will not be entitled to the benefits of the indenture, except for the rights of holders to receive payments on debt securities or the registration of transfer and exchange of debt securities and replacement of lost, stolen or mutilated debt securities.
26

·we may elect to be released from our obligations under some or all of any financial or restrictive covenants applicable to the series of debt securities to which the election relates and from the consequences of an event of default resulting from a breach of those covenants.
To make either of the above elections, we must irrevocably deposit in trust with the trustee enough money to pay in full the principal, interest and premium on the debt securities.  This amount may be made in cash and/or U.S. government obligations or, in the case of debt securities denominated in a currency other than U.S. dollars, cash in the currency in which such series of securities is denominated and/or foreign government obligations.  As a condition to either of the above elections, for debt securities denominated in U.S. dollars we must deliver to the trustee an opinion of counsel that the holders of the debt securities will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the action.
With respect to debt securities of any series that are denominated in a currency other than United States dollars, “foreign government obligations” means:
·direct obligations of the government that issued or caused to be issued the currency in which such securities are denominated and for the payment of which obligations its full faith and credit is pledged, or, with respect to debt securities of any series which are denominated in Euros, direct obligations of certain members of the European Union for the payment of which obligations the full faith and credit of such members is pledged, which in each case are not callable or redeemable at the option of the issuer thereof; or
·obligations of a person controlled or supervised by or acting as an agency or instrumentality of a government described in the bullet above the timely payment of which is unconditionally guaranteed as a full faith and credit obligation by such government, which are not callable or redeemable at the option of the issuer thereof.
Notices
Notices to holders will be given by mail to the addresses of the holders in the security register.
Governing law
The indentures and the debt securities will be governed by, and construed under, the laws of the State of New York.
No personal liability of directors, officers, employees and stockholders
No incorporator, stockholder, employee, agent, officer, director or subsidiary of ours will have any liability for any obligations of ours, or because of the creation of any indebtedness under the debt securities, the indentures or supplemental indentures.  The indentures provide that all such liability is expressly waived and released as a condition of, and as a consideration for, the execution of such indentures and the issuance of the debt securities.
Regarding the trustee
The indentures limit the right of the trustee, should it become our creditor, to obtain payment of claims or secure its claims.
27

The trustee will be permitted to engage in certain other transactions with us.  However, if the trustee acquires any conflicting interest, and there is a default under the debt securities of any series for which it is trustee, the trustee must eliminate the conflict or resign.
Subordinated debt securities
The following provisions will be applicable with respect to each series of subordinated debt securities, unless otherwise stated in the prospectus supplement relating to that series of subordinated debt securities.
The indebtedness evidenced by the subordinated debt securities of any series is subordinated, to the extent provided in the subordinated indenture and the applicable prospectus supplement, to the prior payment in full, in cash or other payment satisfactory to the holders of senior debt, of all senior debt, including any senior debt securities.
Upon any distribution of our assets upon any dissolution, winding up, liquidation or reorganization, whether voluntary or involuntary, marshalling of assets, assignment for the benefit of creditors, or in bankruptcy, insolvency, receivership or other similar proceedings, payments on the subordinated debt securities will be subordinated in right of payment to the prior payment in full in cash or other payment satisfactory to holders of senior debt of all senior debt.
In the event of any acceleration of the subordinated debt securities of any series because of an event of default with respect to the subordinated debt securities of that series, holders of any senior debt would be entitled to payment in full in cash or other payment satisfactory to holders of senior debt of all senior debt before the holders of subordinated debt securities are entitled to receive any payment or distribution.
In addition, the subordinated debt securities will be structurally subordinated to all indebtedness and other liabilities of our subsidiaries, including trade payables and lease obligations.  This occurs because our right to receive any assets of our subsidiaries upon their liquidation or reorganization, and your right to participate in those assets, will be effectively subordinated to the claims of that subsidiary’s creditors, including trade creditors, except to the extent that we are recognized as a creditor of such subsidiary.  If we are recognized as a creditor of that subsidiary, our claims would still be subordinate to any security interest in the assets of the subsidiary and any indebtedness of the subsidiary senior to us.
We are required to promptly notify holders of senior debt or their representatives under the subordinated indenture if payment of the subordinated debt securities is accelerated because of an event of default.
Under the subordinated indenture, we may also not make payment on the subordinated debt securities if:
·a default in our obligations to pay principal, premium, if any, interest or other amounts on our senior debt occurs and the default continues beyond any applicable grace period, which we refer to as a payment default; or
·any other default occurs and is continuing with respect to designated senior debt that permits holders of designated senior debt to accelerate its maturity, which we refer to as a non-payment default, and the trustee receives a payment blockage notice from us or some other person permitted to give the notice under the subordinated indenture.
We will resume payments on the subordinated debt securities:
·in case of a payment default, when the default is cured or waived or ceases to exist, and
28

·in case of a nonpayment default, the earlier of when the default is cured or waived or ceases to exist or 179 days after the receipt of the payment blockage notice.
No new payment blockage period may commence on the basis of a nonpayment default unless 365 days have elapsed from the effectiveness of the immediately prior payment blockage notice.  No nonpayment default that existed or was continuing on the date of delivery of any payment blockage notice to the trustee shall be the basis for a subsequent payment blockage notice.
As a result of these subordination provisions, in the event of our bankruptcy, dissolution or reorganization, holders of senior debt may receive more, ratably, and holders of the subordinated debt securities may receive less, ratably, than our other creditors.  The subordination provisions will not prevent the occurrence of any event of default under the subordinated indenture.
The subordination provisions will not apply to payments from money or government obligations held in trust by the trustee for the payment of principal, interest and premium, if any, on subordinated debt securities pursuant to the provisions described under the section entitled “Satisfaction and discharge; defeasance,” if the subordination provisions were not violated at the time the money or government obligations were deposited into trust.
If the trustee or any holder receives any payment that should not have been made to them in contravention of subordination provisions before all senior debt is paid in full in cash or other payment satisfactory to holders of senior debt, then such payment will be held in trust for the holders of senior debt.
Senior debt securities will constitute senior debt under the subordinated indenture.
Additional or different subordination provisions may be described in a prospectus supplement relating to a particular series of debt securities.
Definitions
“Designated senior debt” means our obligations under any particular senior debt in which the instrument creating or evidencing the same or the assumption or guarantee thereof, or related agreements or documents to which we are a party, expressly provides that such indebtedness shall be designated senior debt for purposes of the subordinated indenture.  The instrument, agreement or other document evidencing any designated senior debt may place limitations and conditions on the right of such senior debt to exercise the rights of designated senior debt.
“Indebtedness” means the following, whether absolute or contingent, secured or unsecured, due or to become due, outstanding on the date of the indenture for such series of securities or thereafter created, incurred or assumed:
·our indebtedness evidenced by a credit or loan agreement, note, bond, debenture or other written obligation;
·all of our obligations for money borrowed;
·all of our obligations evidenced by a note or similar instrument given in connection with the acquisition of any businesses, properties or assets of any kind,

·all of our obligations with respect to letters of credit, bankers’ acceptances and similar facilities, including reimbursement obligations with respect to the foregoing;

·renewals, extensions, modifications, replacements, restatements and refundings of, or any indebtedness or obligation issued in exchange for, any such indebtedness or obligation described in the above clauses of this definition.
“Senior debt” means the principal of, premium, if any, and interest, including all interest accruing subsequent to the commencement of any bankruptcy or similar proceeding, whether or not a claim for post-petition interest is allowable as a claim in any such proceeding, and rent payable on or in connection with, and all fees and other amounts payable in connection with, our indebtedness.  However, senior debt shall not include:
·any debt or obligation if its terms or the terms of the instrument under which or pursuant to which it is issued expressly provide that it shall not be senior in right of payment to the subordinated debt securities or expressly provide that such indebtedness is on the same basis or “junior” to the subordinated debt securities; or
·debt to any of our subsidiaries, a majority of the voting stock of which is owned, directly or indirectly, by us.
“Subsidiary” means a corporation more than 50% of the outstanding voting stock of which is owned, directly or indirectly, by us or by one or more of our other subsidiaries or by a combination of us and our other subsidiaries.  For purposes of this definition, “voting stock” means stock or other similar interests which ordinarily has or have voting power for the election of directors, or persons performing similar functions, whether at all times or only so long as no senior class of stock or other interests has or have such voting power by reason of any contingency.

DESCRIPTION OF UNITS

We may issue units comprised of one or more of the other classes of securities described in this prospectus in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The units may be issued under unit agreements to be entered into between us and a unit agent, as detailed in the prospectus supplement relating to the units being offered. The prospectus supplement will describe:

·the designation and terms of the units and of the securities comprising the units, including whether and under what circumstances the securities comprising the units may be held or transferred separately;

·a description of the terms of any unit agreement governing the units;

·a description of the provisions for the payment, settlement, transfer or exchange of the units;

·a discussion of material federal income tax considerations, if applicable; and

·whether the units if issued as a separate security will be issued in fully registered or global form.

The descriptions of the units in this prospectus and in any prospectus supplement are summaries of the material provisions of the applicable agreements. These descriptions do not restate those agreements in their entirety and may not contain all the information that you may find useful. We urge you to read the applicable agreements because they, and not the summaries, define your rights as holders of the units. For more information, please review the forms of the relevant agreements, which will be filed with the Commission promptly after the offering of units and will be available as described in the section titled “Where You Can Find More Information.”

·the terms of the offering;
·the names of any underwriters, dealers or agents;
·the name or names of any managing underwriter or underwriters;

Sale through underwriters or dealers
If underwriters are used in the sale, the underwriters will acquire the securities for their own account, including through underwriting, purchase, security lending or repurchase agreements.  The underwriters may resell the securities from time to time in one or more transactions, including negotiated transactions.  Underwriters may sell the securities in order to facilitate transactions in any of our other securities (described in this prospectus or otherwise), including other public or private transactions and short sales.  Underwriters may offer securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters.  Unless otherwise indicated in a prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to certain conditions, and the underwriters will be obligated to purchase all the offered securities if they purchase any of them.  The underwriters may change from time to time any public offering price and any discounts or concessions allowed or reallowed or paid to dealers.  The applicable prospectus supplement will include the names of the principal underwriters the respective amount of securities underwritten, the nature of the obligation of the underwriters to take the securities and the nature of any material relationship between an underwriter and us.
Some or all of the securities that we offer through this prospectus may be new issues of securities with no established trading market. Any underwriters to whom we sell securities for public offering and sale may make a market in those securities, but they will not be obligated to do so and they may discontinue any market making at any time without notice. Accordingly, we cannot assure you of the liquidity of, or continued trading markets for, any securities offered pursuant to this prospectus.
If dealers are used in the sale of securities offered through this prospectus, we will sell the securities to them as principals.  They may then resell those securities to the public at varying prices determined by the dealers at the time of resale.  The applicable prospectus supplement will include the names of the dealers and the terms of the transaction.
32

Direct sales and sales through agents
We may sell the securities offered through this prospectus directly.  In this case, no underwriters or agents would be involved.  Such securities may also be sold through agents designated from time to time.  The applicable prospectus supplement will name any agent involved in the offer or sale of the offered securities and will describe any commissions payable to the agent by us.  Unless otherwise indicated in the applicable prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.
We may sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities.  The terms of any such sales will be described in the applicable prospectus supplement.
Delayed delivery contracts
If the applicable prospectus supplement indicates, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase securities at the public offering price under delayed delivery contracts.  These contracts would provide for payment and delivery on a specified date in the future.  The contracts would be subject only to those conditions described in the applicable prospectus supplement.  The applicable prospectus supplement will describe the commission payable for solicitation of those contracts.
Market Informationmaking, stabilization and other transactions
Unless the applicable prospectus supplement states otherwise, each series of offered securities will be a new issue and will have no established trading market.  We may elect to list any series of offered securities on an exchange.  Any underwriters that we use in the sale of offered securities may make a market in such securities, but may discontinue such market making at any time without notice.  Therefore, we cannot assure you that the securities will have a liquid trading market.
Any underwriter may also engage in stabilizing transactions, syndicate covering transactions and penalty bids in accordance with Rule 104 under the Exchange Act, as amended.  Stabilizing transactions involve bids to purchase the underlying security in the open market for the purpose of pegging, fixing or maintaining the price of the securities.  Syndicate covering transactions involve purchases of the securities in the open market after the distribution has been completed in order to cover syndicate short positions.
Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a syndicate covering transaction to cover syndicate short positions.  Stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the securities to be higher than it would be in the absence of the transactions.  The underwriters may, if they commence these transactions, discontinue them at any time.
Derivative transactions and hedging
We, the underwriters or other agents may engage in derivative transactions involving the securities.  These derivatives may consist of short sale transactions and other hedging activities.  The underwriters or agents may acquire a long or short position in the securities, hold or resell securities acquired and purchase options or futures on the securities and other derivative instruments with returns linked to or related to changes in the price of the securities.  In order to facilitate these derivative transactions, we may enter into security lending or repurchase agreements with the underwriters or agents.  The underwriters or agents may effect the derivative transactions through sales of the securities to the public, including short sales, or by lending the securities in order to facilitate short sale transactions by others.  The underwriters or agents may also use the securities purchased or borrowed from us, or others (or, in the case of derivatives, securities received from us in settlement of those derivatives) to directly or indirectly settle sales of the securities or close out any related open borrowings of the securities.
33

Electronic auctions
We may also make sales through the Internet or through other electronic means.  Since we may from time to time elect to offer securities directly to the public, with or without the involvement of agents, underwriters or dealers, utilizing the Internet or other forms of electronic bidding or ordering systems for the pricing and allocation of such securities, you should pay particular attention to the description of that system we will provide in a prospectus supplement.
Such electronic system may allow bidders to directly participate, through electronic access to an auction site, by submitting conditional offers to buy that are subject to acceptance by us, and which may directly affect the price or other terms and conditions at which such securities are sold.  These bidding or ordering systems may present to each bidder, on a so-called “real-time” basis, relevant information to assist in making a bid, such as the clearing spread at which the offering would be sold, based on the bids submitted, and whether a bidder’s individual bids would be accepted, prorated or rejected.  Of course, many pricing methods can and may also be used.
Upon completion of such an electronic auction process, securities will be allocated based on prices bid, terms of bid or other factors.  The final offering price at which securities would be sold and the allocation of securities among bidders would be based in whole or in part on the results of the Internet or other electronic bidding process or auction.
General information
Agents, underwriters, and dealers may be entitled, under agreements entered into with us, to indemnification by us against certain liabilities, including liabilities under the Securities Act.
Agents, underwriters and dealers may engage in transactions with or perform services for us in the ordinary course of their businesses.

LEGAL PROCEEDINGS
We believe Microsoft Corporation is infringing certain of our patents. Accordingly, we commenced a lawsuit against Microsoft on February 15, 2007 by filing a complaint in the United States District Courtsale of the Eastern District of Texas, Tyler Division. Pursuant to the complaint, we allege that Microsoft infringes two of our U.S. patents: U.S. Patent No. 6,502,135 B1, entitled “Agile Network Protocol for Secure Communications with Assured System Availability,” and U.S. Patent No. 6,839,759 B2, entitled “Method for Establishing Secure Communication Link Between Computers of Virtual Private Network Without User Entering Any Cryptographic Information.” On April 5, 2007, we filed an amended complaint specifying certain accused products at issue and alleging infringement of a third, recently issued U.S. patent: U.S. Patent No. 7,188,180 B2, entitled “Method for Establishing Secure Communication Link Between Computers of Virtual Private Network.” We are seeking both damages, in an amount subject to proof at trial, and injunctive relief. Microsoft answered the amended complaint and asserted counterclaims against us on May 4, 2007. Microsoft counterclaimed for declarations that the three patents are not infringed, are invalid and are unenforceable. Microsoft seeks an award of its attorneys’ fees and costs. We filed a reply to Microsoft’s counterclaims on May 24, 2007. Discovery has begun, a Markman hearing on claim construction is scheduled for February 2009, and the trial is scheduled to begin on October 12, 2009. We have served our infringement contentions directed to certain of Microsoft’s operating system and unified messaging and collaboration applications. On March 31, 2008, Microsoft filed a Motion to Dismiss for lack of standing, which was denied by the court pursuant to an order dated June 3, 2008. Also pursuant to that court decision, on June 10, 2008, SAIC joined us in our lawsuit.securities being registered

Because we have determined that Microsoft’s alleged unauthorized use of our patents would cause us severe economic harm and the failure to cause Microsoft to discontinue its use of such patents could result in the termination of our business, we have dedicated a significant portion of our economic resources, to date, to the prosecution of the Microsoft litigation and expect to continue to do so for the foreseeable future.
Although we believe Microsoft infringes three of our patents and we intend to vigorously prosecute this case, at this stage of the litigation the outcome cannot be predicted with any degree of reasonable certainty. Additionally, the Microsoft litigation will be costly and time-consuming, and we can provide no assurance that we will obtain a judgment against Microsoft for damages and/or injunctive relief. Should the District Court issue a judgment in favor of Microsoft, and in connection with such judgment determine that we had acted in bad faith or with fraudulent intent, or we were otherwise found to have exhibited inequitable conduct, the Court could award attorney fees to Microsoft, which would be payable by us.
In the near term, we will dedicate significant time and resources to the Microsoft litigation. The risks associated with such dedication of time and resources are set forth in theRisk Factorssection of this report.
One or more potential intellectual property infringement claims may also be available to us against certain other companies who have the resources to defend against any such claims. Although we believe these potential claims are worth pursuing, commencing a lawsuit can be expensive and time-consuming, and there is no assurance that we will prevail on such potential claims. In addition, bringing a lawsuit may lead to potential counterclaims which may preclude our ability to commercialize our initial products, which are currently in development.
Currently, we are not a party to any other pending legal proceedings, and are not aware of any proceeding threatened or contemplated against us by any governmental authority or other party.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
Boardon behalf of Directors and Shareholders
VirnetX Holding Corporation
We have audited the accompanying consolidated balance sheet of VirnetX Holding Corporation (the “Company”; a development stage enterprise) as of December 31, 2007, and the related consolidated statements of operations, stockholders’ equity (deficit) and cash flows for the year ended December 31, 2007 and the period from August 2, 2005 (date of inception) to December 31, 2007. These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audit.
We conducted our audit in accordance with auditing standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement. The Company has determined that it is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall consolidated financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of the Company as of December 31, 2007, and the results of their operations and their cash flows for the year ended December 31, 2007 and the period from August 2, 2005 (date of inception) to December 31, 2007, in conformity with accounting principles generally accepted in the United States of America.

VirnetX Holding Corporation
(a development stage enterprise)
NOTES TO FINANCIAL STATEMENTS
Note 1  Formation and Business of the Company
VirnetX Holding Corporation (“we,” “us,” “our” or the “Company”) are a development stage company focused on commercializing a patent portfolio for providing solutions for secure real-time communications such as instant messaging, or “IM,” and voice over internet protocol, or “VoIP.”
In July 2007 we effected a merger between PASW, Inc., a company which had at the time of the merger, publicly traded common stock with limited operations, and VirnetX, Inc., which became our principal operating subsidiary. As a result of this merger, the former securityholders of VirnetX, Inc. came to own a majority of our outstanding common stock.
Under generally accepted accounting principles in the United States, the accompanying financial statements have been prepared as if VirnetX, Inc., a company whose inception date was August 2, 2005,any person who is our predecessor for accounting purposes, had acquired PASW, Inc. on July 5, 2007. Accordingly, the accompanying statement of operations include the operations of VirnetX, Inc.or was a director or officer against any loss arising from August 2, 2005 to December 31, 2007any claim asserted against him or her and the operations of PASW, Inc. from July 5, 2007 to December 31, 2007. The historical share activity of VirnetX, Inc. has been retroactively restated to account for the 12.454788 to one exchange rate which was applicableincurred by him or her in any such capacity, subject to certain convertible instruments as explained in Note 10 and Note 11 and for our one for three reverse stock split which was implemented on October 29, 2007.
Our principal business activities to date are our efforts to commercialize our patent portfolio. We also conduct the remaining activities of PASW, Inc., which are generally limited to the collection of royalties on certain internet-based communications by a wholly owned Japanese subsidiary of PASW pursuant to the terms of a single license agreement. The revenue generated by this agreement is not significant.
Although we believe we may derive revenues in the future from our principal patent portfolio and are currently endeavoring to develop certain of those patents into marketable products, we have not done so to date. As such, we are in the development stage and consequently are subject to the risks associated with development stage companies, including the need for additional financings, the uncertainty that our licensing program development efforts will produce revenue-bearing licenses for us, the uncertainty that our development initiatives will produce successful commercial products as well as the uncertainty of marketing and customer acceptance of such products.
These financial statements are prepared on a going concern basis that contemplates the realization of assets and discharge of liabilities in the normal course of business. We have incurred net operating losses and negative cash flows from operations. At December 31, 2007, we had a deficit accumulated in the development stage of $10,975,891. However, management believes the $8,589,000 cash on hand at December 31, 2007 is sufficient to meet our working capital needs for 2008 or until significant revenue is generated from operations.
Note 2  Summary of Significant Accounting Policies
Basis of Presentation
The consolidated financial statements include the accounts of the VirnetX Holding Company, a development stage enterprise, and its wholly owned subsidiaries. All intercompany transactions have been eliminated.
These financial statements reflect the historical results of VirnetX, Inc. and subsequent to the merger date of July 5, 2007, the historical consolidated results of VirnetX Holding Corporation.
Use of Estimates
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and


F-8


VirnetX Holding Corporation
(a development stage enterprise)

NOTES TO FINANCIAL STATEMENTS — (Continued)
the reported amounts of revenues and expenses during the reported period. Actual results could differ from those estimates.
Revenue Recognition
We recognize revenue in accordance with SEC Staff Accounting Bulletin 104. We are a licensor of software and generate revenue primarily from the one-time sales of licensed software. Generally, revenue is recognized upon shipment of the licensed software. For multiple element license arrangements, the license fee is allocated to the various elements based on fair value. When a multiple element arrangement includes rights to a post-contract customer support, the portion of the license fee allocated to each function is recognized ratably over the term of the arrangement.
Cash and Cash Equivalents
We consider all highly liquid investments purchased with original maturities of three months or less at the date of purchase to be cash equivalents.
Property and Equipment
Property and equipment are stated at historical cost, less accumulated depreciation and amortization. Depreciation and amortization are computed using the accelerated and straight line methods over the estimated useful lives of the assets, which range from five to seven years. Repair and maintenance costs are charged to expense as incurred.
Concentration of Credit Risk and Other Risks and Uncertainties
Our cash and cash equivalents are primarily maintained at one financial institution in the United States. Deposits held with this financial institution may exceed the amount of insurance provided on such deposits. The balances are insured by the Federal Deposit Insurance Corporation up to $100,000. During the year ended December 31, 2007 we had, at times, funds that were uninsured. The uninsured balance at December 31, 2007 was in excess of $8,000,000. We have not experienced any losses on our deposits of cash and cash equivalents.
Intangible Assets
We record intangible assets at cost, less accumulated amortization. Amortization of intangible assets is provided over their estimated useful lives, which can range from 3 to 15 years, on either a straight line basis or as revenue is generated by the assets.
Impairment of Long-Lived Assets
We identify and record impairment losses on intangible and other long-lived assets used in operations when events and changes in circumstances indicate that the carrying amount of an asset might not be recoverable. Recoverability is measured by comparison of the anticipated future net undiscounted cash flows to the related assets’ carrying value. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the projected discounted future net cash flows arising from the asset.
Research and Development
Research and development costs include expenses paid to outside development consultants and compensation related expenses for our engineering staff. Research and development costs are expensed as incurred. Acquired


F-9


VirnetX Holding Corporation
(a development stage enterprise)

NOTES TO FINANCIAL STATEMENTS — (Continued)
research and development costs are expensed upon acquisition and are part of total research and development expense.
Income Taxes
We account for income taxes under the asset and liability method. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized.
Effective January 1, 2007, we have adopted FASB Interpretation No. 48 (“FIN 48”), Accounting for Uncertainty in Income Taxes using the prospective method allowed by FIN 48. The adoption of FIN 48 did not have a material impact on our financial statements.
Fair Value of Financial Instruments
Carrying amounts of our financial instruments, including cash and cash equivalents, accounts payable, notes payable, and accrued liabilities approximate their fair values due to their short maturities. The carrying amount of our minimum royalty payment obligation approximates fair value because it is recorded at a discounted calculation.
Stock-Based Compensation
Our accounting for share-based compensation is in accordance with Statement of Financial Accounting Standards No. 123 (revised 2004), “Share-Based Payment,” (“SFAS 123(R)”) which requires the measurement and recognition of compensation expense in the statement of operations for all share-based payment awards made to employees and directors including employee stock-options based on estimated fair values. Using the modified retrospective transition method of adopting SFAS 123(R), the herein financial statements presented reflect compensation expense for stock-based awards as if the provisions of SFAS 123(R) had been applied from the date of inception.
In addition, as required by Emerging Issues Task Force ConsensusNo. 96-18,“Accounting for Equity Instruments that are Issued to Other than Employees for Acquiring, or in Conjunction with Selling Goods or Services,”we record stock and options granted to non-employees at fair value of the consideration received or the fair value of the equity instruments issued as they vest over the performance period.
Earnings Per Share
SFAS No. 128,“Earnings Per Share” requires presentation of basic earnings per share (“Basic EPS”) and diluted earnings per share (“Diluted EPS”). Basic earnings per share is computed by dividing earnings available to common stockholders by the weighted average number of outstanding common shares during the period. Diluted earnings per share is computed by dividing net income by the weighted average number of share outstanding including potentially dilutive securities such as options, warrants and convertible debt. Since we incurred a loss for the period, any common stock equivalents have been excluded because their effect would be anti-dilutive.
Recent Accounting Pronouncements
In December 2007, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 141(R),“Business Combinations” and SFAS No. 160,“Accounting and Reporting of Noncontrolling Interests in Consolidated Financial Statements — an amendment to ARB No. 51.”These Standards will significantly change the accounting and reporting for business combination transactions and noncontrolling (minority) interests in consolidated financial statements, including capitalizing at the acquisition date the fair value of acquired in-process research

VirnetX Holding Corporation

NOTES TO FINANCIAL STATEMENTS — (Continued)
and development, and, remeasuring and writing down these assets, if necessary, in subsequent periods during their development. These new standards will be applied prospectively for business combinations that occur on or after January 1, 2009, except that presentation and disclosure requirements of SFAS 160 regarding noncontrolling interests shall be applied retroactively. The implementation of these standards is not expected to have a material impact on the consolidated statements of operations or financial position.
In December 2007, the FASB ratified EITFNo. 07-1,Accounting for Collaborative Agreements.”This standard provides guidance regarding financial statement presentation and disclosure of collaborative agreements, as defined, which includes arrangements regarding the developing and commercialization of products and product candidates.EITF 07-01 is effective as of January 1, 2009. Implementation of this standard is not expected to have a material impact on the consolidated statements of operations or financial position.
In June 2007, the FASB ratifiedEITF 07-3,Accounting for Nonrefundable Advance Payments for Goods or Services to be used in Future Research and Development Activities.”This standard requires that nonrefundable advance payments for goods and services that will be used or rendered in future research and development activities pursuant to executory contractual arrangements be deferred and recognized as an expense in the period the related goods are delivered or services are performed. EITFNo. 07-3 became effective as of January 1, 2008 and it did not have a material impact on the consolidated statements of operations or financial position upon adoption.
In September 2006, the FASB issued Statement of Financial Accounting Standards No. 157, or SFAS No. 157, “Fair Value Measurements.” SFAS No. 157 provides guidance for using fair value to measure assets and liabilities. It also responds to investors’ request for expanded information about the extent to which companies measure assets and liabilities at fair value, the information used to measure fair value, and the effect of fair valued measurements on earnings. SFAS No. 157 applies whenever standards require (or permit) assets or liabilities to be measured at fair value, and does not expand the use of fair value in any new circumstances. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years, with early adoption permitted, except for the impact of FASB Staff Position (FSP)157-2.FSP 157-2 deferred the adoption of SFAS 157 for non financial assets and liabilities until years ended after November 15, 2008. The Company must adopt these requirements no later than the first quarter of 2008.
On March 19, 2008, the FASB issued SFAS No. 161, “Disclosures about Derivative Instruments and Hedging Activities, an amendment of FASB Statement No. 133 (“SFAS No. 161”). SFAS No. 161 requires enhanced disclosures about an entity’s derivative and hedging activities. These enhanced disclosures will discuss (a) how and why an entity uses derivative instruments, (b) how derivative instruments and related hedged items are accounted for under Statement 133 and its related interpretations, and (c) how derivative instruments and related hedged items affect an entity’s financial position, financial performance, and cash flows. SFAS No. 161 is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008. We have not determined the impact, if any SFAS No. 161 will have on our consolidated financial statements.

Depreciation expense for the years ended December 31, 2007 and 2006 was $18,609 and $7,689, respectively. There was no depreciation expense for the period from August 2, 2005 (date of inception) to December 31, 2005.
Note 4  Patent Portfolio
As of December 31 2007, we had 10 issued U.S. and 8 issued foreign technology related patents, in addition to pending U.S. and foreign patent applications. The term of each issued U.S. and foreign patent runs through 2019. Most of our issued patents were acquired by our principal operating subsidiary, VirnetX, Inc., from Science Applications International Corporation, or SAIC, pursuant to an Assignment Agreement dated December 21, 2006, and a Patent License and Assignment Agreement dated August 12, 2005, as amended on November 2, 2006, including documents prepared pursuant to the November amendment, and as further amended on March 12, 2008. We are required to make payments to SAIC based on the revenue generated from our ownership or use of the patents assigned to us by SAIC. Minimum annual royalty payments of $50,000 are due beginning in 2008. Royalty amounts vary depending upon the type of revenue generating activities, and certain royalty categories are subject to maximums and other limitations. We are also generally required to pay SAIC a portion of proceeds, if any, we receive from the sale of VirnetX, Inc., or from the settlement of certain patent infringement claims of ours. We have granted SAIC a security interest in some of our intellectual property, including the patents and patent applications we obtained from SAIC, to secure these payment obligations.
Generally upon our default of our agreement with SAIC and certain other events, we are required to convey to SAIC our interests in the patents and patent applications acquired from SAIC without consideration.
At December 31, 2007, in accordance with SFAS 142, “Accounting for Goodwill and Other Intangible Assets”, we recorded the fair value of the $50,000 annual guaranteed payments we have agreed to pay to SAIC in 2008 through 2012 as a liability, calculated using a discount rate of 8%. This liability will accrete interest at the 8% rate during the period it is outstanding. We recorded a related asset equal in amount to the liability as an intangible asset which will be amortized over the expected revenue generating period of our agreement with SAIC.
As of December 31, 2007, the expected amortization of the intangible assets is as follows:
     
2008 $48,000 
2009  48,000 
2010  48,000 
2011  48,000 
2012  48,000 
Thereafter  12,000 
     
Total $252,000 
     
As of December 31, 2007, the obligation matures as follows:
     
2008 $48,000 
2009  44,000 
2010  40,000 
2011  36,000

The Plan provides for the granting of stock options and restricted stock units to employees and consultants of ours. Stock options granted under the Plan may be incentive stock options or nonqualified stock options. Incentive stock options (“ISO”) may only be granted to our employees (including officers and directors). Nonqualified stock options (“NSO”) may be granted to our employees and consultants.
Options under the Plan may be granted for period up to ten years and at prices no less than 85% of the estimated fair market value of the shares on the date of grant as determined by the board of directors, provided, however, that the exercise price of an ISO and NSO shall not be less than 100% or 85% of the estimated fair market value of the shares at the date of grant, respectively, and the exercise price of an ISO and NSO granted to a 10% shareholder shall not be less than 110% of the estimated fair value of the shares on the date of grant.

NOTES TO FINANCIAL STATEMENTS — (Continued)
Note 7  Stock-Based Compensation
We account for equity instruments issued to employees in accordance with the provision of SFAS 123(R) which requires that such issuances be recorded at their fair value on the grant date. The recognition of the expense is subject to periodic adjustment as the underlying equity instrument vests.
We have elected to adopt the modified retrospective application method as provided by SFAS 123(R) and, accordingly, financial statement amounts for the periods presented herein reflect results as if the fair value method of expensing equity awards had been applied from inception.
Stock-based compensation expense is included in general and administrative expense for each period as follows:

Total stock-based compensation $818,869  $211,829  $799,920  $1,830,618 
                 
As of December 31, 2007, the unrecorded deferred stock-based compensation balance related to stock options was $8,806,496, which will be amortized as expense over an estimate weighted average vesting amortization period of approximately 3.1 years.
The fair value of each option grant was estimated on the date of grant using the following assumptions:
     
  Year Ended
 Year Ended
  December 31,
 December 31,
  2007 2006
 
Volatility 100% 100%
Risk-free interest rate 3.32% 4.77%
Expected life 6.5 years 6 years
Expected dividends 0% 0%
Based on the Black-Scholes option pricing model, the weighted average estimated fair value of employee stock option grants was $4.96 and $.19 for the years ended December 31, 2007 and 2006, respectively.
The expected life was determined using the simplified method outlined in Staff Accounting Bulletin No. 107 (“SAB 107”), taking the average of the vesting term and the contractual term of the option. Expected volatility of the stock options was based upon historical data and other relevant factors, such as the volatility of comparable publicly-traded companies at a similar stage of life cycle. The Company has not provided an estimate for forfeitures because the Company has no history of forfeited options and believes that all outstanding options at December 31, 2007 will vest. In the future, the Company may change this estimate based on actual and expected future forfeiture rates.

Note 8  Warrants
During 2007, we issued warrants to purchase 266,667 of our common shares at $.75 per share in conjunction with the July stock issuance. The warrants expire in 2012. We issued warrants to purchase 300,000 of our common shares at $4.80 per share to the underwriter of our December 2007 stock issuance. Those warrants are first exercisable in 2008 and expire in 2012.
Note 9  Earnings Per Share
Basic earnings per share is based on the weighted average number of shares outstanding for a period . Diluted earnings per share is based upon the weighted average number of shares and potentially dilutive common shares outstanding. Potential common shares outstanding principally include stock options, warrants, restricted stock units and other equity awards under our stock plan. Since the Company has incurred losses, the effect of any common stock equivalent would be anti-dilutive.

Note 10  Preferred Stock
Our Amended and Restated Certificate of Incorporation, as amended in October 2007, authorizes us to issue 10,000,000 shares of $0.0003 par value per share preferred stock having rights, preferences and privileges to be designated by our Board of Directors. There were no shares of preferred stock outstanding at December 31, 2007. All of the VirnetX, Inc. preferred stock converted into VirnetX, Inc. common stock on a1-for-1 basis immediately prior to the merger between us and VirnetX, Inc., so at the date of the merger, each preferred share of VirnetX, Inc. converted to 12.454788 shares of our common stock. These shares were subsequently adjusted for the impact of the one for three reverse split in October 2007. The VirnetX, Inc. preferred stock outstanding at December 31, 2006 consisted of the following:
                 
Series
 Date Issued Original Issue Price Shares Authorized Shares Outstanding
 
Series A Preferred  March 27, 2006  $1.00   2,000,000   1,404,000 
                 
The preferred stock at December 31, 2006 had voting rights equal to an equivalent number of the common stock into which it was convertible, and voted together as one class with the common stock.
The preferred stock at December 31, 2006 were entitled to receive dividends prior to and in preference to any declaration or payment of dividends on the common stock, at the rate of $0.08 per share per annum on each outstanding share of Series A preferred stock, payable quarterly. Such dividends were payable only when and if declared by the Board of Directors and are not cumulative. No such dividends were ever declared or paid. After payment of such dividends, any additional dividends would be distributed among Series A preferred stock and common stock pro rata based on the number of shares of common stock then held by each holder (assuming conversion of all such Series A preferred stock into common stock.)
The preferred stock at December 31, 2006 had a preference in liquidation of $1,404,000 or $1.00 per share. In the event of liquidation, the holders of Series A preferred shares were entitled to receive preference on any distribution of any assets equal to $1.00 per share, plus any declared but unpaid dividends. The remaining assets, if any, would then be distributed among the holders of common stock and preferred stock, pro rata based on the number of shares of common stock held by each holder, assuming the conversion of all such redeemable convertible preferred stock. If VirnetX, Inc.’s legally available assets were insufficient to satisfy the liquidation preferences, the assets would be distributed ratably among the holders of the Series A preferred stock, in proportion to the amounts each holder would receive if VirnetX, Inc. had sufficient assets and funds to pay the full preferential amount.
The preferred stock at December 31, 2006 had conversion rights, at the option of the holder, into a number of fully paid and non assessable shares of common stock as is determined by dividing $1.00 by the conversion price applicable to such share, determined as hereafter provided, in effect on the due date the certificate is surrendered for

NOTES TO FINANCIAL STATEMENTS — (Continued)
conversion. The initial conversion price per share of Series A preferred stock shall be $1.00 and is subject to adjustments in accordance with antidilution provisions, including stock splits and stock dividends, contained in VirnetX, Inc.’s certificate of incorporation. Each share of Series A preferred stock automatically converts into shares of common stock at the conversion price at the time in effect for such share immediately upon the earlier of (1) VirnetX, Inc.’s sale of its common stock in a firm commitment underwritten public offering which results in aggregate cash proceeds to VirnetX, Inc. of not less than $8,000,000, (2) any reverse merger that yields working capital to VirnetX, Inc. of at least $8,000,000 and which results in VirnetX, Inc.’s shares being registered under Securities Exchange Act of 1934, (3) the date specified by the written consent or agreement of the holders of a majority of the then outstanding shares of Series A preferred stock.
At December 31, 2006, VirnetX, Inc. had reserved sufficient shares of common stock for issuance upon conversion of the convertible preferred stock.
At December 31, 2006 and 2007, the Series A preferred stock was not mandatorily redeemable.
Note 11  Common Stock
Each share of common stock has the right to one vote. The holders of common stock are entitled to receive dividends whenever funds are legally available and when declared by the Board of Directors, subject to the prior rights of holders of all classes of stock outstanding having priority rights as to dividends. No dividends have been declared by the Board from inception through December 31, 2007. The Company’s restated articles of incorporation authorizes the Company to issue up to 100,000,000 shares of $.0001 par value common stock.
In August 2005, the Company issued 13,285,107 shares to founders for aggregate proceeds of $200.
The Company also issued Restricted Stock Units (“RSUs”) to employees and consultants as discussed in Note 7.
All share amounts have been retroactively restated to reflect the conversion rate of 12.454788/1 used to effect the merger between VirnetX, Inc. and VirnetX Holding Corporation and the reverse stock split of 1/3 effective in October 2007.
Note 12  Employee Benefit Plan
During 2007, we sponsored a defined contribution, 401K plan, covering substantially all our employees. The Company’s matching contribution to the plan in 2007 was approximately $5,600. There was no plan in 2006 or 2005.
Note 13  Convertible Debt
In February 2007 we borrowed $500,000 from a group of preferred shareholders. The note accrued interest at 6% and was convertible into our common stock at $.75 per share upon the completion of the transaction in which VirnetX, Inc. came to be our wholly owned subsidiary, or the “Transaction.” Also in February 2007 we borrowed $1,000,000 from a third party. That note paid interest, in cash, at 10% and was convertible into our common stock at $.75 per share upon the completion of the Transaction. A portion, $350,000 of the proceeds of that note were placed as a retainer with our litigation counsel. The same investor purchased $3,000,000 in common stock at $.75 per share, net of expenses of approximately $47,000. That deposit was placed in an escrow account which was released at the close of the Transaction.

Note 14  Short Term Borrowings
During 2007 we borrowed funds on a short-term basis. In June 2007 we borrowed $50,000 at 10% interest. These funds were repaid in July 2007. In December 2007, we borrowed $200,000 in the aggregate from two investors. These funds were repaid, with an aggregate of $2,000 interest, in December 2007.
Note 15  Income Taxes
The Company has Federal and state net operating loss carryforwards of approximately $9,100,000 available to offset future taxable income. The Federal and state loss carryforwards expire beginning in 2025 and 2015 respectively. There are restrictions on the ability of the Company to utilize the benefit in any one year. As a result, the Company has fully reserved any deferred tax benefit from these net operating loss carryforwards.
The Company has Federal and state tax credit carryforwards of approximately $300,000 to reduce future income tax expense. The Federal tax credits expire beginning in 2025. The state tax credits currently do not have an expiration date.
The components of the income tax provision are as follows:

The change in the deferred tax valuation allowance was an increase of $40,000, $660,000 and $3,000,000 in the periods ended 2007, 2006 and 2005, respectively.
Note 16  Merger of VirnetX, Inc. and VirnetX Holding Corporation
In July 2007, VirnetX Holding Corporation consummated a reverse triangular merger in which the Company’s wholly-owned subsidiary merged with and into VirnetX, Inc. with VirnetX, Inc. as the surviving Corporation to the merger. As a result of the merger VirnetX, Inc. became a wholly-owned subsidiary of the Company, and the pre-merger shareholders of VirnetX Inc. exchanged their shares in VirnetX, Inc. for shares of the common stock of the Company. As a result, the VirnetX, Inc. is considered the acquiror of VirnetX Holding Corporation for accounting purposes.

VirnetX Holding Corporation
(a development stage enterprise)

NOTES TO FINANCIAL STATEMENTS — (Continued)
The key terms of the merger include the following:
• Our officers and directors, except for the chief financial officer, were replaced upon completion of the transaction so that the officers and directors of VirnetX, Inc. became our officers and directors.
• VirnetX, Inc.’s convertible notes payable for $1,000,000 and $500,000 were converted into the Company’s common stock in July 2007.
• VirnetX, Inc.’s escrowed convertible note proceeds of $3,000,000 were released from escrow and converted into the Company’s common stock in July 2007.
• The Company issued 29,551,398 shares of our common stock and options to purchase 1,785,186 shares of common stock to the pre-merger shareholders, convertible note holders and option holders of VirnetX, Inc. in exchange for 100% of the issued and outstanding capital stock and securities of VirnetX, Inc. Additionally, we issued to MDB Capital Group LLC and its affiliates, warrants to purchase an aggregate of 266,667 shares of our common stock of the Company pursuant to the provisions of the MDB Service Agreement, which we assumed from VirnetX, Inc. in connection with the merger.
Note 17  Litigation
We believe Microsoft Corporation is infringing certain of our patents. Accordingly, we commenced a lawsuit against Microsoft on February 15, 2007 by filing a complaint in the United States District Court for the Eastern District of Texas, Tyler Division. Pursuant to the complaint, we allege that Microsoft infringes two of our U.S. patents: U.S. Patent No. 6,502,135 B1, entitled “Agile Network Protocol for Secure Communications with Assured System Availability,” and U.S. Patent No. 6,839,759 B2, entitled “Method for Establishing Secure Communication Link Between Computers of Virtual Private Network Without User Entering Any Cryptographic Information.” On April 5, 2007, we filed an amended complaint specifying certain accused products at issue and alleging infringement of a third, recently issued U.S. patent: U.S. Patent No. 7,188,180 B2, entitled “Method for Establishing Secure Communication Link Between Computers of Virtual Private Network.” We are seeking both damages, in an amount subject to proof at trial, and injunctive relief. Microsoft answered the amended complaint and asserted counterclaims against us on May 4, 2007. Microsoft counterclaimed for declarations that the three patents are not infringed, are invalid and are unenforceable. Microsoft seeks an award of its attorneys’ fees and costs. We filed a reply to Microsoft’s counterclaims on May 24, 2007. Discovery has begun and the trial is scheduled to begin on October 12, 2009. We have served our infringement contentions directed to certain of Microsoft’s operating system and unified messaging and collaboration applications. On March 31, 2008, Microsoft filed a Motion to Dismiss for lack of standing, which was denied by the court pursuant to an order dated June 3, 2008. Also pursuant to that court decision, on June 10, 2008, SAIC joined us in our lawsuit.
Although we believe Microsoft infringes three of our patents and we intend to vigorously prosecute this case, at this stage of the litigation the outcome cannot be predicted with any degree of reasonable certainty. Additionally, the Microsoft litigation will be costly and time-consuming, and we can provide no assurance that we will obtain a judgment against Microsoft for damagesand/or injunctive relief. Should the District Court issue a judgment in favor of Microsoft, and in connection with such judgment determine that we had acted in bad faith or with fraudulent intent, or we were otherwise found to have exhibited inequitable conduct, the Court could award attorney fees to Microsoft, which would be payable by us.

Item 16.
Note 1 —Basis of PresentationExhibits
Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States, or GAAP, have been condensed or omitted. Results of operations for the interim periods presented are not necessarily indicative of results which may be expected for any other interim period or for the year as a whole. The accompanying unaudited interim financial statements include all adjustments (consisting of normal recurring adjustments) which are, in the opinion of management, necessary for a fair presentation. The information contained in this report on should be read in conjunction with the audited financial statements and related notes for the year ended December 31, 2007 which are contained in the Company’s Annual Report onForm 10-K filed with the Securities and Exchange Commission, or the SEC, on March 31, 2008.
Note 2 —Formation and Business of the Company
VirnetX Holding Corporation (“we,” “us,” “our” or the “Company”) is a development stage company focused on commercializing a patent portfolio for providing solutions for secure real-time communications such as instant messaging, or IM, and voice over internet protocol, or VoIP.
In July 2007 we effected a merger between PASW, Inc., a company which had at the time of the merger, publicly traded common stock with limited operations, and VirnetX, Inc., which became our principal operating subsidiary. As a result of this merger, the former security holders of VirnetX, Inc. came to own a majority of our outstanding common stock and all of the common shares of PASW, Inc. were exchanged for shares of our common stock.
Under GAAP, the accompanying financial statements have been prepared as if VirnetX, Inc., a company whose inception date was August 2, 2005, who is our predecessor for accounting purposes, had acquired PASW, Inc. on July 5, 2007. Accordingly, the accompanying statements of operations include the consolidated results for the periods ended June 30, 2008 as well as the deficit accumulated during the development stage, which includes the operations of VirnetX, Inc. from August 2, 2005 to June 30, 2008 and the operations of PASW, Inc. from July 5, 2007 to June 30, 2008. The historical share activity of VirnetX, Inc. has been retroactively restated to account for the exchange rate used in affecting the merger and for a one for three reverse stock split completed on October 29, 2007.
Our principal business activities to date are our efforts to commercialize our patent portfolio. We also conduct the remaining activities of PASW, Inc., which are generally limited to the collection of royalties on certain internet-based communications by a wholly owned Japanese subsidiary of PASW, Inc. pursuant to the terms of a single license agreement. The revenue generated by this agreement is not significant.
Although we believe we may derive revenues in the future from our principal patent portfolio and are currently endeavoring to develop certain of those patents into marketable products, we have not done so to date. Because we have limited capital resources, our revenues are insignificant and our expenses, including but not limited to those we expect to incur in our patent infringement case against Microsoft Corporation, (“Microsoft”) are substantial, we may be unable to successfully complete our business plans, our business may fail and your investment in our securities may become worthless.
We are in the development stage and consequently we are subject to the risks associated with development stage companies including: the need for additional financings; the uncertainty that our licensing program development efforts will produce revenue bearing licenses for us; the uncertainty that our development initiatives will produce successful commercial products as well as the marketing and customer acceptance of such products; competition from larger organizations; dependence on key personnel; uncertain patent protection; and dependence on corporate partners and collaborators. To achieve successful operations, we will require additional capital to continue research and development and marketing efforts. No assurance can be given as to the timing or ultimate success of obtaining future funding.

Note 3 —Earnings Per Share
SFAS No. 128, “Earnings Per Share” requires presentation of basic earnings per share and diluted earnings per share. Basic earnings per share are computed by dividing earnings available to common stockholders by the weighted average number of outstanding common shares during the period. Diluted earnings per share is computed by dividing net income by the weighted average number of shares outstanding including potentially dilutive securities such as options, warrants and convertible debt. Because we incurred a loss for each period presented, all such potentially dilutive securities have been excluded because their effect would be anti-dilutive.
Note 4 —Patent Portfolio
As of June 30 2008, we had ten issued U.S. and eight issued foreign technology related patents, and have several pending U.S. and foreign patent applications. The term of each issued U.S. and foreign patent runs through 2019. Most of our issued patents were acquired by our principal operating subsidiary, VirnetX, Inc., from Science Applications International Corporation, or SAIC, pursuant to an Assignment Agreement dated December 21, 2006, and a Patent License and Assignment Agreement dated August 12, 2005, as amended on November 2, 2006, including documents prepared pursuant to the November amendment, and as further amended on March 12, 2008. We are required to make payments to SAIC based on the revenue generated from our ownership or use of the patents assigned to us by SAIC. Minimum annual royalty payments of $50,000 are due beginning in 2008. Royalty amounts vary depending upon the type of revenue generating activities, and certain royalty categories are subject to maximums and other limitations. Generally upon our uncured default on certain material obligations under our agreement with SAIC and certain other events; we require to convey to SAIC our interests in the patents and patent applications acquired from SAIC without consideration. We have granted SAIC a security interest in some of our intellectual property, including the patents and patent applications we obtained from SAIC, to secure these payment obligations.
Generally upon our default of our agreement with SAIC and certain other events, we are required to convey to SAIC our interests in the patents and patent applications acquired from SAIC without consideration.
During the six months ended June 30, 2008, we made our first minimum annual payment of $50,000 to SAIC. As of June 30, 2008, we had not received any royalty revenue on the patents nor begun to amortize the related intangible asset.

Note 6 —Stock Plan
In 2005, VirnetX, Inc. adopted the 2005 Stock Plan, or the Plan, which was assumed by us upon the closing of the transaction between VirnetX Holding Corporation and VirnetX, Inc. on July 5, 2007. The Plan provides for the

VIRNETX HOLDING CORPORATION
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
(Unaudited)
Note 6 —Stock Plan — (Continued)
granting of stock options and restricted stock units to employees, directors and consultants of ours. Stock options granted under the Plan may be incentive stock options or nonqualified stock options. Incentive stock options, or ISOs, may only be granted to our employees (including officers and directors). Nonqualified stock options, or NSOs, may be granted to our employees and consultants.
Options under the Plan may be granted for a period up to ten years and at prices not less than 85% of the estimated fair market value of the shares on the date of grant as determined by the board of directors, provided, however, that the exercise price of an ISO and NSO shall not be less than 100% or 85% of the estimated fair market value of the shares at the date of grant, respectively, and the exercise price of an ISO and NSO granted to a 10% shareholder shall not be less than 110% of the estimated fair value of the shares on the date of grant.
There were 4,238,595 options outstanding at June 30, 2008 and 4,068,595 at December 31, 2007 with an average exercise price of $4.98 at June 30, 2008 and $2.94 at December 31, 2007. As of June 30, 2008, there were 2,881,392 shares available to be granted under the Plan.
There were 170,000 options granted during the period April 1, 2008 through June 30, 2008. No options were exercised in the six months ended June 30, 2008.
Note 7 —Stock-Based Compensation
We account for equity instruments issued to employees in accordance with the provisions of Statement of Financial Accounting Standard No. 123 (revised),Shared-Based Payment,or SFAS 123(R), which requires that such issuances be recorded at their fair value on the grant date. Expense recognized is subject to periodic adjustment as the underlying equity instrument vests. We have elected to adopt the modified retrospective application method as provided by SFAS 123(R) and, accordingly, financial statement amounts for the periods presented herein reflect results as if the fair value method of expensing equity awards had been applied from inception.
Stock-based compensation expense is included in general and administrative expense for each period ended June 30, 2008. Total stock-based compensation expense was $613,848 and $1,145,322 for the three and six months ended June 30, 2008 respectively.
As of June 30, 2008, the unrecorded deferred stock-based compensation balance related to stock options was $9,650,718, which will be amortized as expense over the related vesting period. As of June 30, 2008, the weighted average vesting period was approximately 2.8 years.
The fair value of option grants was estimated on the date of grant using the following assumptions:
         
  Periods Ended
  Year Ended
 
  June 30,
  December 31,
 
  2008  2007 
 
Volatility  100.00%  100.00%
Risk-free interest rate  4.45%  3.32%
Expected life  7 years   6.5 years 
Expected dividends  0.00%  0.00%
Weighted-average grant date fair value of stock options granted $4.96  $4.96 
The expected life was determined using the simplified method outlined in Staff Accounting Bulletin No. 107, or SAB 107, taking the average of the vesting term and the contractual term of the option. Expected volatility of the stock options was based upon historical data and other relevant factors, such as the volatility of comparable publicly-traded companies at a similar stage of life cycle. The Company has not provided an estimate for forfeitures


F-27


VIRNETX HOLDING CORPORATION
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
(Unaudited)
because the Company has no history of forfeited options and believes that all outstanding options at June 30, 2008 will vest. In the future, the Company may change this estimate based on actual and expected future forfeiture rates.
Note 8 —Warrants
During 2007, we issued warrants to purchase 266,667 shares of our common stock at $0.75 per share. The warrants expire in 2012. In January 2008, 233,334 of these warrants were exercised in a cashless exercise transaction. As a result of the January 2008 exercise, a total of 203,910 shares of our common stock were issued. In April 2008, 33,333 of these warrants were exercised in a cashless exercise transaction. As a result of the April 2008 exercise, a total of 28,860 shares of our common stock were issued.
During 2007, we issued warrants to purchase 300,000 shares of our common stock at $4.80 per share to the underwriter of our December 2007 stock issuance. Those warrants are first exercisable in 2008 and expire in 2012.
Note 9 — Litigation
We believe Microsoft is infringing certain of our patents. Accordingly, we commenced a lawsuit against Microsoft on February 15, 2007 by filing a complaint in the United States District Court for the Eastern District of Texas, Tyler Division, or the District Court. Pursuant to the complaint, we allege that Microsoft infringes two of our U.S. patents: U.S. Patent No. 6,502,135 B1, entitled “Agile Network Protocol for Secure Communications with Assured System Availability,” and U.S. Patent No. 6,839,759 B2, entitled “Method for Establishing Secure Communication Link between Computers of Virtual Private Network without User Entering Any Cryptographic Information.” On April 5, 2007, we filed an amended complaint specifying certain accused products at issue and alleging infringement of a third, recently issued U.S. patent: U.S. Patent No. 7,188,180 B2, entitled “Method for Establishing Secure Communication Link between Computers of Virtual Private Network.” We are seeking both damages, in an amount subject to proof at trial, and injunctive relief. Microsoft answered the amended complaint and asserted counterclaims against us on May 4, 2007. Microsoft counterclaimed for declarations that the three patents are not infringed, are invalid and are unenforceable. Microsoft seeks an award of its attorneys’ fees and costs. On March 31, 2008, Microsoft filed its Motion to Dismiss our case. We filed a reply to Microsoft’s counterclaims on May 24, 2007. On June 3, 2008, the court denied the Motion to Dismiss filed by Microsoft. The court’s order denying Microsoft’s motion expressly confirms our constitutional standing to sue for patent infringement. Also pursuant to the court decision on June 10, 2008, San Diego based SAIC (NYSE:SAI) joined us in our lawsuit as a plaintiff. Discovery has begun, a Markman hearing on claim construction is scheduled for February 2009, and the trial is scheduled to begin on October 12, 2009. We have served our infringement contentions directed to certain of Microsoft’s operating system and unified messaging and collaboration applications.
Although we believe Microsoft infringes three of our patents and we intend to vigorously pursue this case, at this stage of the litigation the outcome cannot be predicted. Additionally, the Microsoft litigation will be costly andtime-consuming, and we can provide no assurance that we will obtain a judgment against Microsoft for damagesand/or injunctive relief. Should the District Court issue a judgment in favor of Microsoft, and in connection with such judgment determine that we had acted in bad faith or with fraudulent intent, or we were otherwise found to have exhibited inequitable conduct, the Court could award attorney fees to Microsoft, which would be payable by us.
Because the outcome of this litigation cannot be estimated at this time, we have made no provision for loss or expenses in the accompanying financial statements.

(5)That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer and sell such securities to such purchaser:
(i)Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;
(ii)Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;
(iii)The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and
(iv)Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.
(b)The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(c)Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.  In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding), is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.
(d)The undersigned registrant hereby undertakes that:
(1)For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.
(2)For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(e)The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the Commission under Section 305(b)(2) of the Trust Indenture Act.
