RISK FACTORS
You should consider carefully the risks described below and discussed under the section captioned “Risk Factors” contained in our most recent annual report on Form 10-K, as updated by our subsequent filings under the Securities Exchange Act of 1934, as amended, or the Exchange Act, each of which is incorporated by reference in this prospectus supplement in their entirety, together with other information in this prospectus supplement, and the information and documents incorporated by reference in this prospectus supplement, and any free writing prospectus that we have authorized for use in connection with this offering before you make a decision to invest in our common stock. If any of the following events actually occur, our business, operating results, prospects or financial condition could be materially and adversely affected.  This could cause the trading price of our common stock to decline and you may lose all or part of your investment.  The risks described below are not the only ones that we face.  Additional risks not presently known to us or that we currently deem immaterial may also affect our business operations.
Risks Relating to this Offering
Our 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 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 will 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 dilution 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 this offering.  The shares sold in this offering, if any, will be sold from time to time at various prices. After giving effect to 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 provisions of various vesting schedules and Rule 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 increased 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 public 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, freely 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 Securities Act.
Because 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 do not anticipate declaring or paying any cash dividends in the 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.
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 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 planwish to leverageissue 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 portfoliooffering, the actual total public offering amount, commissions and proceeds to developus, 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 its legal counsel, in an amount not to exceed $125,000.  We estimate that the total expenses for the offering, excluding discounts and commissions payable to Cowen under the terms of the 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 product suite that canparticular transaction, in return for payment of the net proceeds to us.  Sales of our common stock as contemplated in this prospectus supplement will be soldsettled 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 enterprise customersbe received in an escrow, trust or similar arrangement.
Cowen will use its commercially reasonable efforts, consistent with its sales and developers.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 Securities Act and the compensation of Cowen will be deemed to be underwriting commissions or discounts.  We have agreed to provide indemnification and contribution to Cowen against certain civil liabilities, including liabilities under the Securities Act.

·Establish VirnetX as the exclusive universal registry of secure domain names and to enable our customers to act as registrars for their users and broker secure communication between users on different registries.

·Leverage our patent portfolio, technology and software to develop a suite of products that can be sold directly to end-user enterprises.
In furtherance of our strategy, in March 2008, we engaged ipCapital Group to help us support and grow our licensing business. The ipCapital Group is a leading advisor on licensing technology and intellectual property. Through our alliance with ipCapital Group, we are actively engaged in discussions with several potential customers in our target markets. ipCapital Group is led by John Cronin. Prior to founding ipCapital Group, Mr. Cronin was a distinguished inventor at IBM for 17 years where he patented 100 inventions, published over 150 technical papers, received IBM’s “Most Distinguished Inventor Award,” and was recognized as IBM’s “Top Inventor.” As a member of the senior technical staff and the prestigious IBM Academy, Mr. Cronin led an intellectual asset team that spearheaded efforts to produce and manage the development of intellectual property at IBM. Eventually known as “The IBM Patent Factory,” this select group supported the division that increased IBM’s annual licensing revenue from $30 million in 1992 to more than $1 billion in 1997 when Mr. Cronin left IBM. Since its founding in 1998, ipCapital Group has supported the licensing efforts of clients across a variety of technologies and markets, resulting in transactions representing several hundred million dollars of value.
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 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. 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 as a plaintiff. On November 19, 2008, the court granted our motion to amend our infringement contentions, permitting us to provide increased specificity and citations to Microsoft’s proprietary documents and source code to support our infringement case against Microsoft’s accused products, including, among other things, Windows XP, Vista, Server 2003, Server 2008, Live Communication Server, Office Communication Server and Office Communicator. Microsoft was ordered to provide further information regarding its non-infringement contentions and invalidity contentions in light of the amended infringement contentions. Microsoft was also ordered to provide additional e-mail discovery to us. A Markman hearing on claim construction was conducted on February 17, 2009.

On June 9, 2009, we entered into a fixed fee engagement with McKool Smith which confirmed McKool as our lead counsel in the litigation against Microsoft. McKool agreed to represent us in our litigation against Microsoft for a fixed fee of $3 million and a contingency fee of 8% of the litigation proceeds. In the event of a judgment or settlement below an agreed upon amount (designed to approximate the total legal fees associated with the matter), McKool’s fixed fee will be limited to the actual time spent by McKool, up to a maximum of $3 million, plus the contingency fee of 8% of the litigation proceeds. On June 26, 2009, we filed an unopposed motion with the court for an order granting an approximate ninety day continuance of the trial and to enter a new docket control in order to, among other things, allow our new lead counsel to complete the transition from the previous trial counsel as well as adequately prepare for all the upcoming submissions of the expert reports and the subsequent jury trial. This order was granted on June 30, 2009 and the new trial date has been set for March 8, 2010.  With our permission, McDermott Will & Emery filed a motion to withdraw as our counsel from this case, which was granted by the court on July 8, 2009.

On July 30, 2009, the United States District Court for the Eastern District of Texas, Tyler Division, issued its Markman Order in the Microsoft litigation and adopted certain interpretations that we believe are favorable to us on many of the claim terms that were in dispute in the litigation.  The trial in connection with the Microsoft litigation is scheduled to start on March 8, 2010.

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, such judgment could be adverse to 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 the “Risk Factors” section of this prospectus.

RISK FACTORS

You should carefully consider the following material risks in addition to the other information set forth in this prospectus before making any investment in our common stock. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial may also adversely affect our business. If any of these risk factors occurs, you could lose substantial value or your entire investment in our stock.

Risks Related To Existing and Future LitigationSecurities We May Offer
 
We have commenced legal proceedings against Microsoft,may 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 securities 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 tooffer.  A prospectus supplement, which we allege that Microsoft infringes twowill provide each time we offer securities, will describe the specific amounts, prices and terms of our patents regarding the creation of virtual private networks (“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.  On February 17, 2009, a Markman hearing on claim construction was conducted and on July 30, 2009, the court issued its Markman Order.  Although we believe that the court adopted certain interpretations in the Markman Order that are favorable to us, we cannot assure you that the litigation will result in an outcome that is favorable to our company or our stockholders.  
In addition to pursuing the commercialization of our GABRIEL Connection Technologytm and our portfolio of intellectual property, given the scope and importance of the Microsoft litigation to us, we expect to allocate a majority of the proceeds we earn from the private placement transaction covered by this prospectus towards the fees and expenses associated with the Microsoft litigation.  Although we have entered into a fixed fee engagement with McKool Smith on June 9, 2009 to act as our lead counsel in connection with the Microsoft lawsuit, we anticipate that the legal proceedings against Microsoft may continue for several years and may require significant expenditures for legal fees and other expenses.   In addition, as the McKool Smith litigation team focuses on trial preparation immediately prior to the commencement of the trial in March 2010, we anticipate that our legal fees will increase with such active preparation.  Although we view the McKool Smith fixed fee arrangement as a positive arrangement and one that will help us manage our expenses in connection with the litigation, we anticipate that our legal fees and other expenses associated with this litigation will be material and will negatively impact our financial condition and results of operations.  Such impact may result in our inability to continue our business or to pursue other business initiatives not associated with the Microsoft litigation.

The time and effort required 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.  
While we believe Microsoft infringes our patents, we can provide no assurance that we will be successful in our lawsuit.these securities.
 
We believe that Microsoft infringes on threemay sell the securities to or through underwriters, dealers or agents or directly to purchasers or as otherwise set forth below under “Plan 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.Distribution.” 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 adversely affected and 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, although our business strategy is focused primarily on bringing patented products to market, our business strategy also 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 ability to pursue the Microsoft litigation.
As a public company, our management must devote substantial time, attention and financial resources 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 that will be available to Microsoft as well as any other future litigation opponents.  We may, from time to time, be required to disclose information that will have a material adverse affectagents acting on our litigation strategies.  This information may enable our litigation opponentsor their behalf, reserve the sole right to develop effective litigation strategiesaccept and to reject in whole or in part any proposed purchase of securities. Each prospectus supplement will set forth the names of any underwriters, dealers, agents or other entities involved in the sale of securities described in that are contrary to our interests.prospectus supplement and any applicable fee, commission or discount arrangement with them.
 
We may commence additional legal proceedings against third parties who we believe are infringing on our intellectual property rights, and 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 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 and the existence and outcome of any such litigation could harm our business.  In addition, 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 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 our patent portfolio, or part of it, is commercialized.  We may 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.  Our inability to generate sufficient cash flow or raise other funds to meet our expenses, obligations and sustain our operations raises substantial doubt about our ability to continue as a going concern.  See the “Liquidity and Capital Resources” section in our Quarterly Report on Form 10-Q filed with the SEC on August 10, 2009 for additional information.

We anticipate incurring operating losses and negative cash flows for 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 and there is no assurance that we will be able to do so.  As discussed in the notes to the condensed consolidated financial statements included in our Quarterly Report on Form 10-Q filed with the SEC on August 10, 2009, in the event that we are unable to achieve profitability or raise sufficient funding to cover our losses in the near term, we will be unable to meet our expenses and obligations as they come due, and this raises substantial doubts as to our ability to continue as a going concern.  The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Our business plan for commercializing our patents and technology 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 a security platform for real-time communications; however, this is not a defined market.  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 communications based on SIP or using DNS lookup protocols as well as customer adoption of our GABRIEL Communication TechnologyTM and our secure domain name registry.  We cannot assure you that customers will adopt our products and services, or that we will succeed in building a profitable business based on our business plan.
We may or may not be able to capitalize on potential market opportunities related to our licensing strategy or our patent portfolio.
Our business strategy calls for us to enter into licensing relationships with the leading companies in our target market in order to reach a larger end-user base than we could reach through direct sales and marketing efforts.  We have engaged ipCapital Group to help develop our licensing strategy and to introduce us to five potential strategic licensees of our technology.  In connection with this engagement, we agreed to pay ipCapital Group 10% of the royalties of each resulting licensing arrangement, up to an aggregate maximum of $2 million per licensee, or $10 million in the aggregate.  There can be no assurance that we will be able to capitalize on the potential market opportunity.  Our inability to generate licensing revenues associated with the potential market opportunity 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;

·we may not be successful in entering into licensing relationships with our targeted customers on commercially acceptable terms; and

·the validity of our patents underlying the licensing opportunity is currently being challenged in our litigation against Microsoft.

Our business greatly depends on the growth of IM, VoIP, mobile services, streaming video, file transfer and remote desktop and other next-generation Internet-based applications.
We cannot assure you that next-generation Internet-based applications such as instant messaging (“IM”,) voice over Internet protocol (“VoIP”,) mobile services, streaming video, file transfer and remote desktop will continue to gain widespread market acceptance.  The Internet may ultimately prove not to be a viable commercial marketplace for such applications for a number of reasons, including:
·unwillingness of consumers to shift to VoIP and use other such next-generation Internet-based applications;

·refusal to purchase security products to secure information transmitted through such applications;

·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;

·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.
If the market for IM, VoIP, mobile services, streaming video, file transfer and remote desktop does not grow as anticipated, our business would be adversely affected.
The success of our products that secure IM, VoIP, mobile services, streaming video, file transfer and remote desktop, among other real-time communications applications, depends on the growth in the number of users, which in turn depends on the Internet gaining more widespread acceptance as the basis for these real-time communications applications.  These real-time communications applications are still in early stages of market acceptance and we cannot assure you that they will continue to develop a broader audience.  For example, 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 inconvenience.
While the use of IM and other next-generation Internet-based applications has grown rapidly in personal and professional use, there can be no assurance that users will pay to secure their use of such applications.
Many services such as Microsoft, Yahoo! and America Online offer IM free of charge.  However, security solutions for these services are not free, and OEMs may not want to adopt such security solutions if users of IM do not see the value and do not want to pay for such security solutions.  If personal and professional users of IM and other next-generation Internet-based solutions do not want to pay for the security solutions, we will have difficulty marketing and selling our products and technologies.

We expect that we will experience long and unpredictable sales cycles, which may impact our quarterly operating results.
We expect that our sales cycles will be long and unpredictable due to a number of uncertainties such as:
·the need to educate potential customers about our patent rights and our product and service capabilities;

·customers’ willingness to invest potentially substantial resources and modify their network infrastructures to take advantage of our products;

·customers’ budgetary constraints;

·the timing of customers’ budget cycles; and

·delays caused by customers’ internal review processes.
We expect that we will be substantially dependent on a concentrated number of customers.  If we are unable to establish, maintain or replace our relationships with customers and develop a diversified customer base, our revenues may fluctuate and our growth may be limited.
We expect that for the foreseeable future, a significant portion of our revenues will be generated from a limited number of customers.  There can be no guarantee that we will be able to obtain such customers, or if we do so, to sustain our revenue levels from these customers.  If we cannot establish, maintain or replace the limited group of customers that we anticipate will generate a substantial majority of revenues, or if they do not generate revenues at the levels or at the times that we anticipate, our ability to maintain or grow our revenues will 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 and IP-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, launch and/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 patented 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.
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 products and/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.
Our products are highly technical and may contain undetected errors, which could cause harm to our reputation and adversely affect our business.
Our products are highly technical and complex and, when deployed, may contain errors or defects.  In addition, we rely on third parties for software development and technology services, and there may be errors in the development processes used by our third party counterparts that may adversely affect our end products.  Despite testing, some errors in our products may only be discovered after a product has been installed and used by customers.  Any errors or defects discovered in our products after commercial release could result in failure to achieve market acceptance, loss of revenue or delay in revenue recognition, loss of customers and increased service and warranty cost, any of which could adversely affect our business, operating results and financial condition.  In addition, we could face claims for product liability, tort or breach of warranty, including claims relating to changes to our products made by our channel partners.  The performance of our products could have unforeseen or unknown adverse effects on the networks over which they are delivered as well as on third-party applications and services that utilize our services, which could result in legal claims against us, harming our business.  Furthermore, we expect to provide implementation, consulting and other technical services in connection with the implementation and ongoing maintenance of our products, which typically involves working with sophisticated software, computing and communications systems.  We expect that our contracts with customers will contain provisions relating to warranty disclaimers and liability limitations, which may not be upheld.  Defending a lawsuit, regardless of its merit, is costly and may divert management’s attention and adversely affect the market’s perception of us and our products.  In addition, if our business liability insurance coverage proves inadequate or future coverage is unavailable on acceptable terms or at all, our business, operating results and financial condition could be adversely impacted.

Malfunctions of third-party communications infrastructure, hardware and software exposes us to a variety of risks we cannot control.
In addition, our business will also depend upon the capacity, reliability and security of the infrastructure owned by third parties that we will use to deploy our offerings.  We have no control over the operation, quality or maintenance of a significant portion of that infrastructure or whether or not those third parties will upgrade or improve their equipment.  We depend on these companies to maintain the operational integrity of our connections.  If one or more of these companies is unable or unwilling to supply or expand its levels of service to us in the future, our operations could be severely interrupted.  Also, to the extent the number of users of networks utilizing our future products suddenly increases, the technology platform and secure 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 communications; 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.

System failure or interruption or our failure to meet increasing demands on our systems could harm our business.
The success of our license and service offerings will depend on the uninterrupted operation of various systems, secure data centers and other computer and communication networks that we establish.  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, service interruptions or delays or system failures.  Our systems and operations will also be vulnerable to damage or interruption from:
·power loss, transmission cable cuts and other telecommunications failures;

·damage or interruption caused by fire, earthquake, and other natural disasters;

·computer viruses or software defects; and

·physical or electronic break-ins, sabotage, intentional acts of vandalism, terrorist attacks and other events beyond our control.
System interruptions or failures and increases or delays 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.  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.
Any significant problem with our systems or operations could result in lost revenue, customer dissatisfaction or lawsuits against us.  A failure in the operation of our secure domain name registration system could result in the inability of one or more registrars to register and maintain secure domain names for a period of time.  A failure in the operation or update of the master directory that we plan to maintain could result in deletion or discontinuation of assigned secure domain names for a period of time.  The inability of the registrar systems we establish, including our back office billing and collections infrastructure, and telecommunications systems to meet the demands of an increasing number of secure domain name requests could result in substantial degradation in our customer support service and our ability to process registration requests in a timely manner.
If we experience security breaches, we could be exposed to liability and our reputation and business could suffer.
We will retain certain confidential customer information in our secure data centers and secure domain name registry.  It will be critical to our business strategy that our facilities and infrastructure remain secure and are perceived by the marketplace to be secure.  Our secure domain name registry operations will also depend on our ability to maintain our computer and telecommunications equipment in effective working order and to reasonably protect our systems against interruption, and potentially depend on protection by other registrars in the shared registration system.  The secure domain name servers that we will operate will be critical hardware to our registry services operations.  Therefore, we expect to have to expend significant time and money to maintain or increase the security of our facilities and infrastructure.
10

Security technologies are constantly being tested by computer professionals, academics and “hackers.”  Advances in the techniques for attacking security solutions could make some or all of our products obsolete or unmarketable.  Likewise, if any of our products are found to have significant security vulnerabilities, then we may need to dedicate engineering and other resources to eliminate the vulnerabilities and to repair or replace products already sold or licensed to our customers.  Despite our security measures, our infrastructure may be vulnerable to physical break-ins, computer viruses, attacks by hackers or similar disruptive problems.  It is possible that we may have to expend additional financial and other resources to address such problems.  Any physical or electronic break-in or other security breach or compromise of the information stored at our secure data centers and domain name registration systems may jeopardize the security of information stored on our premises or in the computer systems and networks of our customers.  In such an event, we could face significant liability and customers could be reluctant to use our services.  Such an occurrence could also result in adverse publicity and therefore adversely affect the market’s perception of the security of electronic commerce and communications over IP networks as well as of the security or reliability of our services.

We may incur significant expenses and damages because of liability claims.
An actual or perceived breach of our security solutions could result in a product liability claim against us.  A substantial product liability claim against us could harm our operating results and financial condition.  In addition, any actual or perceived breach of our security solution, whether or not caused by the failure of one of our products, could hurt our reputation and cause potential customers to turn to our competitors’ products.
Our ability to sell our solutions will be dependent on the quality of our technical support, and our failure to deliver high-quality technical support services could have a material adverse effect on our sales and results of operations.
If we do not effectively assist our customers in deploying our products, succeed in helping our customers quickly resolve post-deployment issues and provide effective ongoing support, or if potential customers perceive that we may not be able achieve to the foregoing, our ability to sell our products would be adversely affected, and our reputation with potential customers could be harmed.  In addition, as we expand our operations internationally, our technical support team will face additional challenges, including those associated with delivering support, training and documentation in languages other than English.  As a result, our failure to deliver and maintain high-quality technical support services to our customers could result in customers choosing to use our competitors’ products instead of ours in the future.
There has been increased competition for security solutions 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.
We expect competition for our products and services to be intense.  We expect to compete directly against other companies offering similar security products and services that will compete directly with our proposed products and services.  We also expect that we will compete against established vendors within the IP-telephony, mobility, fixed-mobile convergence and unified communications markets.  These companies may incorporate other competitive technologies into their product offerings, whether developed internally or by third parties.  For the foreseeable future, substantially all of our competitors are likely to be 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.
If we are not able to adequately protect our patented rights, our operations would be negatively impacted.
11

Our ability to compete largely depends on the superiority, uniqueness and value of our technology and intellectual property.  To protect our intellectual property 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;

·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 patented rights would have a negative impact on our operations and revenues.
In addition, legal standards relating to the validity, enforceability, and scope of protection of intellectual property rights in Internet-related businesses are uncertain and still evolving.  Because of the growth of the Internet and Internet related businesses, patent applications are continuously and simultaneously being filed in connection with Internet-related technology.  There are a significant number of U.S. and foreign patents and patent applications in our areas of interest, and we believe that there has been, and will likely continue to be, significant litigation in the industry regarding patent and other intellectual property rights.
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 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.
When we attempt to implement our secure domain name registry services business, we may be subject to government and industry regulation and oversight which may impede our ability to achieve our business strategy.
The U.S. government has historically controlled the authoritative domain name system (“DNS”) root server since the inception of the Internet.  On July 1, 1997, the President of the United States directed the U.S. Secretary of Commerce to privatize the management of the domain name system in a manner that increases competition and facilitates international participation in its management.
On September 29, 2006, the U.S. Department of Commerce extended its delegation of authority by entering into a new agreement with the Internet Corporation for Assigned Names and Numbers (“ICANN”) a California non-profit corporation headquartered in Marina Del Rey, California.  ICANN is responsible for managing the accreditation of registry providers and registrars that manage the assignment of top level domain names associated with the authoritative DNS root directory.  Although other DNS root directories are possible to create and manage privately without accreditation from ICANN, the possibility of conflicting name and number assignments makes it less likely that users would widely adopt a top level domain name associated with an alternative DNS root directory provided by a non-ICANN-accredited registry service.
On June 26, 2008, ICANN announced that it will be relaxing its prior position and will begin to issue generic top level domain names (“gTLDs”) more broadly than it had previously.  ICANN expects to begin to take applications for gTLDs in April or May of 2009 with an application fee of $100,000 or more per application.  ICANN expects the first of these customized gTLDs to be issued in the fourth quarter of 2009.
12

We are currently evaluating whether we will apply to become an ICANN-accredited registry provider with respect to one or more customized gTLDs, or create our own alternative DNS root directory to manage the assignment of non-standard secure domain names.  We have not yet begun discussions with ICANN and we cannot assure you that we will be successful in obtaining ICANN accreditation for our registry service on terms acceptable to us or at all.  Whether or not we obtain accreditation from ICANN, we will be subject to the ongoing risks arising out of the delegation of the U.S. government’s responsibilities for the domain name system to the U.S. Department of Commerce and ICANN and the evolving government regulatory environment with respect to domain name registry services.
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, state and/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.  The U.S. Federal Communications Commission has imposed some traditional telephony requirements on VoIP such as disability access requirements and other obligations.  It is possible that federal and state legislatures may seek to impose increased fees and administrative burdens on VoIP, data and video providers.  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 laws and/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 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 the Internet 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 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.
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.  We have no employment agreements with any of our key executives that prevent them from leaving us at any time.  In addition, we do not maintain key person life insurance for any of our officers or key employees.  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.  Competition for engineering, sales, marketing and executive personnel is intense, particularly in the technology and Internet sectors and in the regions where our facilities are located.  We can provide no assurance that we will attract or retain such personnel.
13

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;

·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 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.
We will continue to incur significant costs as a result of being a public company.
As a public company, we will continue to 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 legal and financial compliance costs and to make some activities more time-consuming and costly, and these costs could be material to us.
Failing to maintain the effectiveness of our internal control over financial reporting could cause the cost related to remediation to increase and could cause our stock price to decline.
In the future, our management may identify deficiencies regarding the design and effectiveness of our system of internal control over financial reporting that we engage in pursuant to Section 404 of the Sarbanes-Oxley Act (“Section 404”) as part of our periodic reporting obligations.  Such deficiencies could include those arising from turnover of qualified personnel or arising as a result of acquisitions, which we may not be able to remediate in time to meet the continuing reporting deadlines imposed by Section 404 and the costs of which may harm our results of operations.  In addition, if we fail to maintain the adequacy of our internal controls, as such standards are modified, supplemented or amended from time to time, we may not be able to ensure that our management can conclude on an ongoing basis that we have effective internal controls.  We also may not be able to retain an independent registered public accounting firm with sufficient resources to attest to and report on our internal controls in a timely manner.  Moreover, our registered public accounting firm may not agree with our management’s future assessments and may deem our controls ineffective if we are unable to remediate on a timely basis.  If in the future we are unable to assert that we maintain effective internal controls, our investors could lose confidence in the accuracy and completeness of our financial reports which could cause our stock price to decline.
14

Our ability to sell our solutions will be dependent on the quality of our technical support, and our failure to deliver high-quality technical support services could have a material adverse effect on our sales and results of operations.
If we do not effectively assist our customers in deploying our products, succeed in helping our customers quickly resolve post-deployment issues and provide effective ongoing support, or if potential customers perceive that we may not be able achieve the foregoing, our ability to sell our products would be adversely affected, and our reputation with potential customers could be harmed.  In addition, as we expand our operations internationally, our technical support team will face additional challenges, including those associated with delivering support, training and documentation in languages other than English.  As a result, our failure to deliver and maintain high-quality technical support services to our customers could result in customers choosing to use our competitors’ products instead of ours in the future.
Risks Related to Our Stock
The exercise of our outstanding warrants may result in a dilution of our current stockholders' voting power and an increase in the number of shares eligible for future resale in the public market which may negatively impact the market price of our stock.

The exercise of some or all of our outstanding warrants could significantly dilute the ownership interests of our existing stockholders. As of September 30, 2009, we had outstanding warrants to purchase an aggregate of 12,271,946 shares of common stock, including (i) the warrant to purchase 300,000 shares of common stock issued to the underwriter of our December 2007 issuance, (ii) the warrants to purchase 1,235,000 shares of common stock at an exercise price of $2.00 per share issued pursuant to our January 2009 offering, (iii) the warrants to purchase 1,235,000 shares of common stock at an exercise price of $3.00 per share issued pursuant to our January 2009 offering, (iv) the warrants to purchase 1,235,000 shares of common stock at an exercise price of $4.00 per share issued pursuant to our January 2009 offering, (v) the warrant to purchase 220,000 shares of common stock at an exercise price of $1.80 per share issued to the underwriter of our January 2009 offering, (vi) the warrants to purchase 3,246,959 shares of common stock underlying the Series I Warrants issued pursuant to the private placement transaction covered by this Registration Statement, (vii) the warrants to purchase up to 2,419,045 shares of common stock underlying the Series II Warrants issued pursuant to the private placement transaction covered by this Registration Statement, and (viii) the warrants to purchase up to 2,380,942 shares of common stock underlying the Series III Warrants issued pursuant to the private placement transaction covered by this Registration Statement.  To the extent warrants are exercised, additional shares of common stock will be issued, and such issuance will dilute existing stockholders and increase the number of shares eligible for resale in the public market.  Please see the section in this prospectus entitled “Description of Warrants Issued in the Private Placement Transaction” for a tabular discussion of the theoretical impact of the warrants issued in this private placement transaction and the effects of the issuance of shares underlying such warrants on existing stockholders’ economic and percentage ownership.  Additionally, the issuance of up to 3,167,890 shares of common stock issuable upon exercise of vested stock options and other awards outstanding as of September 30, 2009 pursuant to our incentive plan will further dilute our existing stockholders’ voting interest.

In addition to the dilutive effects described above, the exercise of those securities would lead to a potential increase in the number of shares eligible for resale in the public market. Sales of substantial numbers of such shares in the public market could adversely affect the market price of our shares.

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.  The holders of any debt securities or instruments we may issue would have rights superior to the rights of our common stockholders.
Trading in our common stock is limited and the price of our common stock may be subject to substantial volatility, particularly in light of the instability in the financial and capital markets, and we may be unable to maintain the standards for the continued listing of our common stock on the NYSE Amex.
15

Our common stock is listed on NYSE Amex but its daily trading volume has been limited, sporadic and volatile. Over the past year, the market price of our common stock has experienced significant fluctuations.  Between June 30, 2008 and September 30, 2009, the reported last sale price for our common stock has ranged from $4.65 to $1.06 per share.  With such volatility, there can be no assurance that we will remain qualified to be listed on NYSE Amex.

In April 2009, we received a letter from the NYSE Amex stating that, based on the NYSE Amex’s review of publicly available information, we were considered to be below the NYSE Amex’s continued listing standards.  After submitting a plan of compliance to the NYSE Amex and additional evaluation by the Exchange, we were informed in October 2009 that we had resolved the continued listing deficiencies.  We cannot assure you that we will not receive additional deficiency letters in the future, or that we will continue to satisfy the continued listing standards in order to remain listed on the Exchange.

If our securities were delisted from trading on NYSE Amex and we are unable to list our securities on another securities exchange, our securities may be able to be listed on the OTC Bulletin Board or the “Pink Sheets,” which may adversely affect the liquidity and price of our common stock.  In addition, we expect the price of our common stock to continue to be volatile as a result of a number of factors, including, but not limited to, the following:
·developments in our litigation against Microsoft;

·large purchases or sales of common stock;

·actual or anticipated announcements of new products or services by us or our competitors;

·general conditions in the markets in which we compete; and

·general 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 September 30, 2009, our executive officers and directors beneficially owned an aggregate of 10,777,792 shares, or approximately 27% of our then-outstanding common stock. In addition, a group of stockholders that, as of December 31, 2007, held 4,766,666 shares, or approximately 12% 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 stockholder 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.
Our protective provisions could make it 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 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.
16

·
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 Bylaws:  Stockholder proposals to alter or amend our Bylaws or to adopt new Bylaws can only be approved by the affirmative vote of at least 66 2/3% 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.
Our business is subject to risks associated with the ongoing financial crisis and weakening global economy.
The recent severe tightening of the credit markets, turmoil in the financial markets, and weakening global economy impacts our ability to raise needed capital and enter into customer agreements.  These slowdowns are expected to worsen if these economic conditions are prolonged or deteriorate further.  Further, these conditions and uncertainty about future economic conditions make it challenging for us to forecast our operating results, make business decisions, and identify the risks that may affect our business, financial condition and results of operations.  If we are not able to timely and appropriately adapt to changes resulting from the difficult macroeconomic environment, our business, financial condition, and results of operations may be significantly negatively affected.

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.
USE OF PROCEEDS
All shares of our common stock offered by this prospectus are being registered for the account of the selling security holders. We will not receive any of the proceeds from the sale of these shares. However, if a selling security holder exercises a Series I or a Series III warrant in order to obtain underlying shares of common stock to sell, we would receive cash proceeds if the exercise price is paid in cash.  Assuming that all Series I and Series III warrants were exercised in cash, and including the proceeds received by us at the closing of the private placement transaction, the total proceeds we will receive from the transaction will be approximately $22,292,759. We will not receive any proceeds from the cashless exercise of the Series II Warrants.

We anticipate that all net proceeds obtained from this private placement transaction will be used to fund our working capital purposes.  Given our relatively low overhead structure and the importance of a successful result of the Microsoft litigation to us, we anticipate that the majority of the proceeds we raise in this private placement transaction will be allocated to fund the fees and expenses associated with our Microsoft litigation.  See the section in this prospectus entitled “Risk Factors:  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 adversely affected and we may not survive.” and other related risk factors in this prospectus for our discussion of the importance and the cost-intensive nature of the Microsoft litigation.  We also anticipate that, as we get closer to the start of the trial portion of the litigation in March 2010, our legal fees will accordingly increase.

17

We anticipate using a majority of the remaining portion of the proceeds towards the commercialization of our patented GABRIEL Connection Technologytm and our intellectual property portfolio, and towards the establishment of the exclusive secure domain name registry in the United States and other international key markets.  Should we not raise the total anticipated proceeds in this transaction, and we are not therefore able to allocate such proceeds to the Microsoft litigation, our intellectual property offerings, and other general working capital purposes, we may need to raise additional funds through, but not limited to, public or private offerings, third-party debt facilities, or strategic partnerships.  See the section in this Prospectus entitled “Risk Factors:  We may seek to raise additional funds, finance acquisitions, or develop strategic relationships by issuing capital stock that would dilute your ownership.” for additional disclosure regarding the potential dilutive impact that such additional raises would have on our existing stockholders.
DIVIDEND POLICY
We have not in the past paid, and 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.

THE PRIVATE PLACEMENT TRANSACTION
On September 11, 2009, we completed a private placement transaction in which we issued (i) 2,380,942 shares of our common stock, (ii) Series I Warrants to purchase 3,246,959 shares of common stock, of which up to 627,923 shares of common stock are issuable pursuant to certain anti-dilution adjustment provisions in the Series I Warrants, (iii) Series II Warrants to purchase up to 2,419,045 shares of common stock, and (iv) Series III Warrants to purchase 2,380,942 shares of common stock.  The private placement transaction resulted in aggregate gross proceeds of approximately $6,000,000 paid to us at closing.  The terms of the transaction required that we agree to register for public resale the shares of common stock being offered pursuant to this prospectus.  

Dawson James Securities, Inc. (“Dawson James”) acted as placement agent in connection with the private placement of the common stock and warrants.  As compensation for providing such services, Dawson James received a cash fee of $600,000 and a Series I Warrant to purchase 238,094 shares of the Company’s common stock.  In the event the Series III Warrants are exercised in full, Dawson James will be entitled to another $600,000 as a cash fee.

PLAN OF DISTRIBUTION
The selling security holders 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 covered hereby on the principal trading market or any other stock exchange, market or trading facility on which the shares are traded or in private transactions.  These sales may be at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale, or negotiated prices.  The selling security holders 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 entered into after the effective date of the registration statement of which this prospectus is a part;

·in transactions through broker-dealers that agree with the selling security holders to sell a specified number of such shares at a stipulated price per share;

·through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

·a combination of any such methods of sale; or

·any other method permitted pursuant to applicable law.
The selling security holders may also sell shares under Rule 144 under the Securities Act of 1933, as amended, if available, rather than under this prospectus.

Broker-dealers engaged by the selling security holders may arrange for other brokers-dealers to participate in sales.  Broker-dealers may receive commissions or discounts from the selling security holders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2440; and in the case of a principal transaction, a markup or markdown in compliance with FINRA IM-2440.
In connection with the sale of the common stock or interests therein, the selling security holders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume.  The selling security holders may also sell shares of the common stock short and deliver these securities to close out their short positions or to return borrowed shares in connection with such short sales, or loan or pledge the common stock to broker-dealers that in turn may sell these securities.  The selling security holders may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).
The selling security holders 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 or discounts under the Securities Act.  Each selling security holder has informed the Company that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the common stock. In no event shall any broker-dealer receive fees, commissions and markups which, in the aggregate, would exceed eight percent (8%).

The Company is required to pay certain fees and expenses incurred by the Company incident to the registration of the shares.  The Company has agreed to indemnify the selling security holders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.
23

The selling security holders will be subject to the prospectus delivery requirements of the Securities Act including Rule 172 thereunder unless an exemption therefrom is available.

The selling security holders have advised us that there is no underwriter or coordinating broker acting in connection with the proposed sale of the resale shares by the selling security holders.

We agreed to keep this prospectus effective until the earlier of (i) the date on which the shares may be resold by the selling security holders without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144 and without the requirement for the Company to be in compliance with the current public information under Rule 144 under the Securities Act or any other rule of similar effect or (ii) all of the shares have been sold pursuant to this prospectus or Rule 144 under the Securities Act or any other rule of similar effect.  The resale shares will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale shares of common stock covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale shares may not simultaneously engage in market making activities with respect to the common stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution.  In addition, the selling security holders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of shares of the common stock by the selling security holders or any other person.  We will make copies of this prospectus available to the selling security holders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

There can be no assurance that any selling security holder will sell any or all of the shares of common stock registered pursuant to the registration statement, of which this prospectus forms a part.

Once sold under the registration statement, of which this prospectus forms a part, the shares of common stock will be freely tradable in the hands of persons other than our affiliates.

The issuance of preferred stock will affect, and may adversely affect, the rights of holders of common stock. It is not possible to state the actual effect of the issuance of any shares of preferred stock on the rights of holders of common stock until the board of directors determines the specific rights attached to that preferred stock. The effects of issuing preferred stock could include one or more of the following:
·restricting dividends on the common stock;
·diluting the voting power of the common stock;
·impairing the liquidation rights of the common stock; or
·delaying or preventing changes in control or management of our company.
We have no present plans to issue any shares of preferred stock nor are any shares of our preferred stock presently outstanding.  Preferred stock will be fully paid and nonassessable upon issuance.
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:
·Undesignated Preferred Stock.  The ability to authorize undesignated preferred stock makes it possible for our board of directors to issue one or more 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 the effect of deferring hostile takeovers or delaying changes 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 stockholder 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 committee 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 us, because it generally makes it more difficult for stockholders to replace a majority of the directors.
·Limits on Ability of Stockholders to Act by Written Consent.  We have provided in our certificate of incorporation that our stockholders may not act by written consent. 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 result, a holder 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 election of directors.

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 date of the transaction, the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;
·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 officers, and (b) shares owned by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or
·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 two-thirds of the outstanding voting stock that is not owned by the interested stockholder.
Generally, 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 associates, 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 dividend 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.
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.
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.
DESCRIPTION OF THE WARRANTS
General
We may issue warrants for the purchase of our debt securities, preferred stock or common stock, or any combination thereof.  Warrants may be issued independently or together with our debt securities, preferred stock or common stock and may be attached to or separate from any offered securities.  Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a bank or trust company, as warrant agent.  The warrant agent will act solely as our agent in connection with the warrants.  The warrant agent will not have any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants.  This summary of certain provisions of the warrants is not complete.  For the terms of a particular series of warrants, you should refer to the prospectus supplement for that series of warrants and the warrant agreement for that particular series.

Description of Warrants Issued in The Private Placement Transaction

The materialfollowing description sets forth selected general terms and provisions of the three formsapplicable indenture and debt securities to which any prospectus supplement may relate.  Other specific terms of warrantsthe applicable indenture and debt securities will be described in the applicable prospectus supplement.  If any particular terms of the indenture or debt securities described in a prospectus supplement differ from any of the terms described below, then the terms described below will be deemed to have been superseded by that prospectus supplement.
General
Debt securities may be issued in separate series without limitation as to aggregate principal amount.  We may specify a maximum aggregate principal amount for the transactiondebt securities of any series.
We are summarized below.  This summarynot limited as to the amount of debt securities we may issue under the indentures.  Unless otherwise provided in a prospectus supplement, a series of debt securities may be reopened to issue additional debt securities of such series.

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.
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 qualifiedprocedures 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.
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.
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 entiretyrights 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:
(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 three formsmodification or amendment.
We may also make modifications and amendments to the indentures for the benefit of warrant filedholders 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;
·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.
·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 exhibitsa 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 current reportcreditor, to obtain payment of claims or secure its claims.
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 Form 8-Kthe 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 filedare 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
·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.

There were three forms of warrants exercisable for shares of our common stock issued in the private placement transaction to the investors:  the Series I Warrant, the Series II Warrant and the Series III Warrant.DESCRIPTION OF UNITS

Series I WarrantWe 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 Series I Warrants give the investors in the transaction rights to purchase the same number of shares purchased in the transaction over a 5-year term at an exercise price equal to 125%designation and terms of the price per share paid in the transaction, subject to anti-dilution protection that could reduce the exercise price; provided however, that in no event shall such exercise price be reduced to less than $3.17 (the closing price per share of our common stock) subject to adjustments for reverseunits and forward stock splits, stock dividends, stock combinations and other similar transactions affecting the Company’s common stock. The Series I Warrants are not exercisable until March 11, 2010 and expire on March 11, 2015.  Aside from the anti-dilution adjustment associated with the exercise price premium, the Series I Warrants are not subject to any further adjustments with respect to the exercise price or number of shares covered.  The aggregate number of shares of common stock registered by this prospectus includes 627,907 shares of our common stock issuable pursuant to the anti-dilution protection provisions described above.  We will not receive proceeds from any shares issued pursuant to the anti-dilution protection provisions.
Series II Warrant

The Series II Warrants give the investors in the transaction pricing protection for the transaction with a floor price of $1.25 per share.  In the event the market price of our common stock declines between the closing of the transactionsecurities comprising the units, including whether and under what circumstances the earlier of (i) 15 business days aftersecurities comprising the date this Registration Statement is declared effective and (ii) the date Rule 144 becomes available for resale of the common stock registered pursuant to this prospectus (such date that is the earlier of clause (i) and (ii) is referred to in this registration statement as the “Warrant Exercise Date”), the Series II Warrants willunits may be automatically exercised on a cashless exercise basis and a number of additional shares will be issued to the investors in order to effectively reduce the per share purchase price paid in the private placement transaction to the greater of (i) 80% of the 15-day volume weighted average trading price per share of our common stock immediately prior to the Warrant Exercise Date and (ii) $1.25 per share.  At the Warrant Exercise Date, the Series II Warrants will either be automatically exercised on a cashless exercise basis if our stock price is lower at the Warrant Exercise Date as described above,held or they will terminate unexercised.  The adjustment associated with the Series II Warrants does not affect either the exercise price or number of shares covered by either the Series I Warrants or the Series III Warrants.
Series III Warrant
At the Warrant Exercise Date, the Series III Warrants give the investors in the transaction a 60-day right to purchase an additional $6.0 million of our common stock at $2.52 per share.  The Series III Warrants are not subject to any adjustments with respect to the exercise price or number of shares covered.
The following table shows the number of shares of common stock that might be issued upon the exercise of each series of warrants, the time frame during which each series of warrants can be exercised, and the effects of the issuance of shares of common stock on existing stockholders’ economic and percentage ownership, calculated on a theoretical basis.

(3) Assuming a stock price of $2.05, the Series I and Series III Warrants each have an exercise price in excess of the publicly traded stock price. 
(4) Assuming a stock price of $2.05 per share and that 39,750,927 shares are outstanding, the total market capitalization would equal approximately $81,489,400.  If the Series II Warrants were fully exercised, the number of shares outstanding would increase by 2,419,045 shares of common stock to bring the total aggregate number shares outstanding to 42,169,972. Such an increase would theoretically reduce the market capitalization on a per share basis to $1.93.

Warrant Accounting

Currently, our outstanding warrants derive from three transactions: (1) the warrants issued to the underwriter of the December 2007 stock offering, (2) the warrants issued to the public and the warrants issued to the underwriter in the January 2009 offering, and (3) the warrants issued to the investors and the placement agent in the private placement transaction covered by this prospectus.
The warrants issued in the September 2009 offering that are covered by this prospectus are accounted for in accordance with the Emerging Issues Task Force 07-05, and are accounted for as equity transactions where the warrants are indexed to the Company's own stock.

The disclosures for the warrants follow the guidance of Accounting Standards Council 505 accounting standards council under the new FASB codification.

Protective Provisions

We have a number of protective provisions that could delay, discourage or prevent a third party from acquiring the company 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 the Board of Directors since it will take two annual meetings to effectively replace at least three directors which represents a majority of the Board of Directors.
transferred separately;

·
Blank check preferred stock:  our Boarda description of Directors has the authority to establishterms of any unit agreement governing 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 exiting 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 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 will have the ability to do so in the future very rapidly and without stockholder approval.
units;

·
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 votedescription of the stockholders must provide notice to us within very specific date windows in order to haveprovisions for the matter voted on atpayment, settlement, transfer or exchange of 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.
units;

·
Eliminationa discussion of stockholder actions by written consent:  this has the effect of eliminating the ability of a stockholder or a group of stockholders representing a majority of the outstanding shares to take actions rapidlymaterial federal income tax considerations, if applicable; 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 towhether the By-laws:  our By-laws mayunits if issued as a separate security will be alteredissued in fully registered or amended or new By-laws adopted by the affirmative vote of at least 66-2/3% of the outstanding shares.

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.
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.
