PART I

the most direct and appropriate means of delivery, based on the sender’s and recipient’s communications environment and preferences. The service supports a number of encrypted email delivery mechanisms, including S/MIME, TLS, OpenPGP, “push” delivery and secure portal delivery. These last two mechanisms enable users to send messages instantly and securely to anyone with an email address, including those who do not have an encryption tool. ZixCorp’s Best Method of Delivery makes the technology simple for end users and provides flexibility and ease of implementation for information technology professionals. The Company believes this ability to send messages through different modes of delivery makes ZixCorp’s Email Encryption Service superior to competitive offerings.

     ZixCorp’s Email Encryption Service employs a centralized directory of users called the ZixDirectory ™ , which the Company considers a key differentiator of its offering. The ZixDirectory operates as a global “White Pages” for email encryption. ZixDirectory today contains over ten million user’s email addresses or encryption codes, and has recently grown at a rate of over 70,000 per week. Access to these email addresses or encryption codes in the ZixDirectory, greatly improves ease of use for both senders and receivers of secure email. The ZixDirectory uses PKI (Public Key Infrastructure) functionality for email encryption without the implementation burden or cost of typical PKI infrastructures. Using the ZixDirectory, all ZixCorp customers have completely transparent email encryption amongst themselves, while being able to deliver encrypted email to anyone using the Best Method of Delivery. ZixCorp’s Email Encryption Service is focused on ease of use for the senders and recipients of encrypted email, while affording them the option of strong encryption methods, extended feature sets and the flexibility of a variety of fully integrated and fully interoperable solutions.

     Today in healthcare, ZixCorp’s Email Encryption Service is used by thirty Blue Cross Blue Shield companies, including WellPoint, as well as Cigna, Humana and over 1,000 hospitals. In the finance sector, ZixCorp serves over 500 banks, credit unions and savings and loan companies as well as all of the FFIEC regulators. The Company also has contracts with nineteen state banking regulators covering various state agencies in those states.

     ZixCorp has several options for delivering its Email Encryption Service, which are detailed below.

      ZixVPM ^® — ZixVPM (Virtual Private Messenger) is a policy-based email encryption gateway for privacy and compliance. This appliance-based service is the primary configuration in which ZixCorp’s Email Encryption Service is delivered today.

     Since ZixVPM is generally installed near the periphery of the enterprise’s network and in their email path, end users are not required to install any software or obtain encryption codes to secure their email messages. ZixVPM encrypts email for an enterprise’s customers and business partners without requiring the enterprise to create, deploy, or manage end user encryption keys or desktop software.

     ZixVPM is delivered with built-in policy management features, auditing and reporting functions, including a set of lexicons with validated policies to assist organizations in their efforts to meet guidelines and regulations, such as the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”) and Gramm-Leach-Bliley Act (“GLBA”).

      ZixConnect™ — ZixConnect is a managed Transport Layer Security (TLS) protocol service. With ZixConnect, clients use a single TLS connection, established and maintained by ZixCorp, to send and receive encrypted emails with key business partners. While the customer needs to establish only one connection to the Company, ZixCorp can maintain hundreds of connections on the other end to ensure delivery to the customer’s targeted recipients. For example, financial institutions use ZixConnect to communicate directly with their regulators and partners without the need for additional hardware or software at their facility

      ZixDirect ^® — ZixDirect is an extension of ZixCorp’s Best Method of Delivery for ZixVPM to deliver encrypted emails directly to a recipient’s inbox, allowing access while working offline. It is ideal for sending email securely to customers or business partners that do not have email encryption capabilities.

      ZixPort ^® — ZixPort is a browser-based, secure e-messaging portal solution. It is hosted, monitored, and managed in the ZixData Center. ZixPort is easily deployed and has little or no impact on a company’s existing information technology, Web, or security infrastructures. It is ideal for companies that want to extend their brand by including secure email communications as part of their portal experience.

      ZixMail ^® — ZixMail is a subscription-based desktop email encryption application. It enables users to easily send and receive encrypted, digitally signed communications to any email address, even if the recipient does not subscribe to Zix services. ZixMail uses ZixCorp’s Best Method of Delivery to enable recipients who are not ZixMail subscribers to receive and reply to ZixMail messages at no charge through the ZixMessage Center.

      ZixAuditor ^® — ZixAuditor is an assessment service used to analyze, document, and report on the nature and characteristics of an organization’s email with the purpose of identifying regulated, high-risk, or proprietary content. It allows organizations to assess the level of risk they have with sensitive information being communicated via email. ZixAuditor is built around a set of lexicons that enables the identification of messages containing health, financial, human resources, and other legally protected or proprietary information.

      Email Encryption Competition: ZixCorp’s service differs from the products and services of its competitors. ZixCorp offers a hosted service offering, while most competitors offer a product-based approach that the customer builds and runs themselves. Some of these competing companies have substantial information technology security and email protection products; however, the Company believes that the ZixDirectory provided through its subscription hosted service, offers many advantages in the marketplace. Specifically, the ZixDirectory allows the sharing of user id’s for encryption and interoperability between users in a community of interest- healthcare, finance or government, for instance. Competitive offerings provide software that customers must install and operate themselves. Because each customer builds and operates their own system, the directory of user id’s that they create are not shared and different companies encrypted email systems are not interoperable.

     In addition, ZixCorp offers technology solutions that are both user friendly and easy to deploy and can be made operational quickly compared to the longer deployment cycles common with the solutions of many competitors. This capability is particularly important when it is necessary to communicate with external networks, as is the case with the healthcare and financial services markets. The Company’s registered users become part of the ZixDirectory, a global “white pages” that enables instant secure communications with other ZixCorp registered users using the Company’s centralized key management system and overall unique approach to implementing secure e-messaging technology. The Company enables secure communications with non-registered users via ZixDirect or ZixPort.

     The Company’s Email Encryption Service focuses on the secure (encryption) delivery portion of the secure e-messaging market, a sub-segment of the e-messaging management and protection market. The Company has been listed as an industry leader in a prominent study that compared eight qualified email encryption vendors. Companies operating in this portion of the market include content management companies such as Tumbleweed Communications Corp. and other secure delivery participants such as PGP Corporation, Certified Mail, Authentica, Voltage Security, PostX (recently acquired by Cisco Systems Inc.), Secure Computing and Sigaba Corporation. Technically, while these companies offer “send-to-anyone” encrypted email, ZixCorp believes they are unable to offer the benefits that come from access to the ZixDirectory and from using the Company’s Best Method of Delivery protocol. Nevertheless, some of these competitors are large enterprises with substantial financial and technical resources that exceed those possessed by the Company.

     Furthermore, ZixCorp believes that technology alone cannot solve customers’ challenges and the Company offers several programs that add business value to its technology services. The Company’s audit and assessment service enables prospects and customers to establish a baseline understanding of the security issues within their e-messaging systems prior to deploying ZixCorp’s solutions on an ongoing basis to ensure continued compliance with security best practices.

     Moreover, the Company does not believe that its competitors have made the investments required to match its infrastructure development and services. Only ZixCorp offers a complete secure delivery package: robust email encryption from the sender’s computer desktop, robust email encryption from the sender’s network server, policy management from the sender’s network server and a full array of benefits and managed services provided by the ZixData Center. This complete secure delivery solution differentiates the Company’s service from all other secure e-document delivery and secure e-messaging market participants. Nevertheless, some or all of the Company’s competitors could develop products and services that are superior to those offered by the Company.

e-Prescribing

      Segment Overview: Increasingly, healthcare transactions previously conducted in person or on paper are being converted to electronic methods. To meet this need, ZixCorp has leveraged its core competency in the secure transmission of electronic data to expand into e-prescribing.

     The Company believes that e-Prescribing delivers many benefits, including improved patient safety through alerts to potential adverse drug or allergy interactions, reduced calls from the pharmacy to the physician, reduced costs for patients and their insurers through increased prescribing within drug formulary guidelines, increased delivery of prescribed drugs via mail order and reduced prescribing errors. The ZixCorp e-prescribing application not only delivers the foregoing benefits, but it can also be used as a technology platform to deliver related products and additional point-of-care services to improve the efficiency and effectiveness of physicians by providing greater access to information and other decision making support tools. The Company believes that the growing interest in lowering healthcare costs in both the private and public sectors while using information technology to improve the quality of health care opens up additional opportunities for acceptance of these services. Of the over 580,000 physicians in the United States (“U.S.”), ZixCorp has had particular success in deploying its service to high-prescribing physicians who practice in offices of five physicians or less. The Company estimates this segment of the physician market to be over 100,000 doctors and believes this segment has not been directly targeted by large healthcare information technology vendors. ZixCorp believes that the market opportunity for e-prescribing and the additional point-of-care services to this segment of physicians is significant.

     ZixCorp designs and develops its e-Prescribing solution and distributes it directly to physicians and healthcare institutions. The Company has entered into sponsorship programs whereby large health insurance companies (payors), have agreed to provide the e-prescribing devices and service free of charge for various periods of time to associated physicians. ZixCorp generally sells this as an annual service with an initial set-up and hardware charge. Typically, the third-party sponsors agree to pay for the physicians’ use of the service, or at least most of the initial set-up costs and first year of service, because they have a vested benefit in the cost savings associated with use of this technology.

      e-Prescribing Services and Solutions : ZixCorp’s e-Prescribing technology enables medical providers to write and transmit prescriptions electronically from the point of care directly to the pharmacy. In addition to enabling providers to write and transmit prescriptions electronically, ZixCorp’s e-Prescribing offers point-of-care access to real-time drug formularies and comprehensive drug data. The result is significant time savings from fewer illegible prescriptions; enhanced patient safety from checking drug-to-drug and drug-allergy interactions; significant cost savings to healthcare payors and pharmacy benefit managers from higher formulary compliance, generic drug prescribing, and mail-order use; and fewer office resources dedicated to managing prescriptions.

      PocketScript ^® — PocketScript is ZixCorp’s e-Prescribing service. The service works with a handheld wireless Personal Data Assistant (“PDA”) or a secure Web site to provide physicians with the ability to write and transmit prescriptions directly to any pharmacy. In addition, providers can view available patient drug histories obtained from third parties for the purpose of confirming that prescriptions are being filled and safeguarding against duplication of therapies. The system also identifies generics and preferred drugs for multiple formularies enabling providers to choose the most appropriate option. The comprehensive prescription drug database, which PocketScript provides under license from a third party, provides information on virtually every drug available, including drug-to-drug interactions, drug-allergy interactions and a drug reference guide.

     In association with various PocketScript abilities, the Company sells and markets certain transaction-based offerings to various customers. These transaction-based fees are evolving as the e-prescribing market develops. Pharmacy Benefit Managers (“PBM”), pharmacies and associated network operators have industry experience which has led to evolving transaction fees, some payable to point-of-care vendors, which reflect a component of operational cost savings and/or are designed to incent industry adoption of their services. Some payors are adopting similar models based mostly on anticipation of prescription drug savings. Other payors are implementing shared savings models which correlate real financial results with our transaction and utilization data to calculate payments. The Company believes that the fees it receives attributable to the transactional element of e-Prescribing will become increasingly significant as more subscribers are added to the service or more contracts contain the transactional element.

      e-Prescribing Competition: In general, ZixCorp’s e-Prescribing service competes in a less developed market than the Company’s mail Encryption Service. However, because of recent advances in healthcare technology, advances in handheld computing, and the civic and legislative mandates to reduce healthcare costs and increase patient safety, this market is seeing increases in competitive activity. The Company believes however, that its experience during the last four years shows it can successfully deploy e-prescribing technology and achieve adoption and utilization. Therefore, the Company believes its existing contracts, which include five Blue Cross Blue Shield companies and two large national payors, along with its deployment and utilization success, gives it significant competitive advantage.

     However, despite these advantages, ZixCorp has several competitors. These include AllScripts Healthcare Solutions, Dr. First, Inc., InstantDX LLC, iScribe, Prematics, and RxNT. Many of the competitors in this market also focus on other technologies such as patient records automation and practice management solutions, or they act as application service providers in the healthcare market.

     Companies that do not currently compete with ZixCorp or only compete with selected products or in selected markets could become competitors in the future on a larger scale. Companies such as GE Healthcare or McKesson Corporation would likely offer a broad portfolio of health information technologies for all or some of the pharmaceutical, pharmacy, healthcare provider and managed care markets. With considerable size and access to capital, they could become significant competitors. Favorable legislative mandates (see “Regulatory Drivers for Market Growth” ) may make their entry into the market more likely.

Regulatory Drivers for Market Growth

     In 2002, ZixCorp chose to focus a significant portion of its Email Encryption product development and sales efforts on the healthcare market. The Company believed that it was a sector with a clear need for secure communications as it has regulatory requirements for strict privacy and protection of data through HIPAA (which mandates eliminating paper flow and providing privacy and security for protected health information, and which also increased emphasis on improving efficiency and reducing costs in the delivery of health care) and consequences for noncompliance. The Company has been successful in securing market share for its Email Encryption Service. There was a significant increase in demand in the healthcare sector leading up to the April 2005 HIPAA Security Rule deadline and sales in this sector have remained strong since that time. Recently, there have been indications of an increased emphasis on the enforcement of the HIPAA regulations within the Department of Health and Human Services, so the Company believes that near-term demand in the healthcare sector may continue.

     Additional federal regulations, such as GLBA, and state regulations across the country have enhanced security awareness in vertical markets outside of healthcare, and have prompted affected organizations to consider adopting systems that ensure data security and privacy. Even where there are no specific regulations, corporations may demand email protection to adhere to evolving industry best practices for protecting sensitive information. In 2003, ZixCorp responded to these trends by expanding the Company’s focus beyond healthcare into other vertical markets including financial services, insurance and government. As part of the strategy to penetrate the financial services sector, the Company targeted the relevant regulators who themselves were placing an increased emphasis on the secure transmission of sensitive information. The Company currently has federal regulators who comprise the Federal Financial Institution Examination Council as customers and is a recommended solution of the Conference of State Bank Supervisors, which regulates the more than 6,000 state-chartered banks in the U.S. ZixCorp also currently has the state banking regulators in eighteen states as customers. The Company believes that having banks and other financial institutions receiving encrypted email containing the branding “Secured by ZixCorp” from their regulators has helped raise the awareness of and interest in its Email Encryption Service.

     In e-Prescribing, the Company sees regulatory developments as a catalyst for increasing demand. In the Medicare Prescription Drug and Modernization Act of 2004, e-prescribing is specifically addressed in Section 1860D-4 and also in the subsequent final rule on the Medicare Prescription Drug Benefit, which states that Part D sponsors that participate in the Part D program are required to support and comply with electronic prescribing standards. In January 2006, the initial Foundation Standards for e-prescribing went into effect, with Final Standards to be issued after additional standards are tested. Also, in January 2006, the Centers for Medicare and Medicaid Services announced funding for four pilot demonstration projects to study the impact of those proposed additional

standards. ZixCorp participated in two such grants, one awarded to its strategic partner, SureScripts ^® , and another with the Rand Corporation. In July 2006, the Institute of Medicine released its study, “Preventing Medication Errors,” in which it found there were 1.5 million injuries per year from medication errors costing over $3.5 billion annually (not including the impact of lost wages and productivity) and resulting in 7,000 deaths per year. This study also calls for universal e-prescribing by 2010. In October 2006, the Department of Health and Human Services issued final regulations in support of the adoption of e-prescribing with the creation of new safe harbors to the federal Anti-Kickback Statute and exceptions to the federal Physician Self-Referral Law, also known as “Stark,” which together should facilitate additional funding for e-prescribing programs. As the costs for the ongoing Medicare Prescription Drug Benefit are fully recognized, technologies such as e-prescribing become more attractive as they can reduce the amount of spending on drugs. In December 2007, a bipartisan group of senators and representatives introduced the E-MEDS Act of 2007, which called for a one-time bonus and an increase in Medicare reimbursement levels for physicians who e-prescribe and would also over time make e-prescribing a requirement for Medicare prescriptions. Although legislation of this nature was not voted on in 2007, the Company believes there is a likelihood that mandating e-prescribing for Medicare and Medicaid prescriptions will be addressed in 2008, and, if were to become law, it could significantly impact the demand for e-prescribing applications. Of course, a federal mandate would also make it more likely that other competitors, including those possessing more financial, technical, and other resources than the Company, would enter the market.

Sales and Marketing

     The Company primarily sells its Email Encryption Service through a direct sales force that focuses on larger accounts and a telesales force that focuses on small to medium-sized businesses. The Company also uses a network of resellers and other distribution partners, particularly other service providers seeking an encryption offering in an OEM-like relationship. In 2005, the Company began a program to place greater emphasis on these distribution channels, with the expectation that they will become a more significant source of revenues in the future. In 2007, 5% of the Company’s new first-year Email Encryption sales came from these OEM partners.

     The Company has also historically focused most of its selling and marketing efforts towards the healthcare sector. Prior to 2003, the healthcare market had been the Company’s highest priority, given the legislative requirements of HIPAA. In 2007, approximately half of the Company’s new first-year orders still came from healthcare. Since late 2003, the Company has expanded its Email Encryption Service sales and marketing efforts to include the financial services, insurance and government sectors, with the financial services sector becoming a second core customer segment for the Company. In 2007, about one-third of the new orders came from the financial services sector.

     For e-Prescribing, the Company has not emphasized sales directly to physicians but rather has focused on other stakeholders that benefit from healthcare technology. In particular, eight health insurance companies (payors) have purchased ZixCorp’s services on behalf of the prescribing doctors in their plans. Because of the potential savings resulting from lower drug spend and improved patient safety, these insurance companies have, in effect, underwritten the deployment and initial subscription costs of the service for the physicians. After a sponsorship agreement is signed, the Company works closely with payors to effectively market and deploy the service to physicians. Within these programs, ZixCorp has found success in targeting physicians who practice in offices of five doctors or less, which constitute an estimated 75% of high-prescribing physicians in practice today. The Company believes this approach satisfies a need with these smaller practices for healthcare IT and accelerates adoption and utilization. The Company’s e-prescribing service was first successfully deployed in the Massachusetts market in 2004. The Company currently has sponsorship contracts which support activity in eleven states for its e-prescribing service. The Company will continue to target these insurance companies to expand in new areas within these existing states and to fund additional programs in other areas of the United States. The Company must expand existing sponsorships and sign additional sponsors for the deployment of e-prescribing technology to be successful in the e-prescribing market.

Employees

     ZixCorp had 155 employees as of December 31, 2007, with 67 employees categorized under the Email Encryption segment, 67 employees categorized under the e-Prescribing segment, and 21 employees categorized as Corporate. The majority of the Company’s employees are located in Dallas, Texas; Burlington, Massachusetts; and Ottawa, Ontario, Canada.

Research and Development; Patents and Trademarks

     ZixCorp’s continuing operations incurred research and development expenses of $5,322,000, $6,085,000, and $6,520,000, in 2007, 2006, and 2005, respectively.

     The Company’s patents protect certain elements of the Company’s core technology underlying the Company’s Email Encryption business. ZixCorp has not realized any revenues from licensing any of its patents to third parties. The Company received no new U.S. patents in 2007. The expenses for research and development listed under Corporate in 2005 were comprised of activities dedicated to divested products.

     The following are registered marks of ZixCorp and certain of its subsidiaries: “ZixCorp,” “ZixMail,” “ZixAuditor,” “ZixVPM,” “ZixDirect,” “ZixPort,” “ZixWorks,” and “PocketScript.”

Availability of Raw Material; Working Capital Items

     Because the Company provides a service, raw materials are not an important part of its business. However, both segments do require hardware: servers for Email Encryption and handheld devices and related networking hardware for e-Prescribing. As a general practice, the Company maintains a 60 to 90 day supply of inventory on hand. If availability were to become an issue with a particular supplier, ZixCorp could, if required, obtain needed hardware from multiple vendors and perform quality and assurance testing within the 60 to 90 day period. In the fourth quarter of 2006, the Company received an end-of-life product notice from its e-Prescribing handheld device vendor. As a result, the Company procured additional quantities of handheld devices to accommodate 2007 forecasted deployments. With the supply of handheld devices resolved as of December 31, 2007, inventory levels had returned to normal maintenance levels of 60 to 90 days supply.

Compliance with Environmental Regulations

     The Company has incurred no, and does not expect to incur, material expenditures or obligations related to environmental compliance issues.

Governmental Contracts

     While the Company does have several contracts with state and federal regulators, it does not have a material portion of its business related to contracts with governmental agencies.

Significant Customers

     In 2007, no single customer accounted for 10% or more of the Company’s revenues. In 2006 and 2005, e-Prescribing customer Blue Cross and Blue Shield of Massachusetts, Inc., accounted for approximately 13%, or $2,413,000, and 17%, or $2,323,000, of total revenues, respectively. These revenues accounted for approximately 57% and 78%, of e-Prescribing revenues for 2006 and 2005, respectively. No other single customer accounted for 10% or more of the Company’s revenues in these periods.

     As of December 31, 2007, the backlog is comprised of the following elements: $16,103,000 of deferred revenue that has been billed and paid, $3,328,000 billed but unpaid, and approximately $12,361,000 of unbilled contracts. Excluded from the backlog at December 31, 2006, is a customer deposit from sanofi-aventis of $2,000,000, which was the remaining balance of an original $4,000,000 customer deposit made in January 2004. The Company had previously concluded that the deposit would likely be forfeited and not be recognized as revenue; and, therefore, should not be included in backlog. In 2007, this deposit was forfeited and recorded in Operating Expenses as Customer Deposit Forfeiture (see Note 12 to the consolidated financial statements).

     The backlog is recognized into revenue as the services are performed. Approximately 45% of the total backlog is expected to be recognized as revenue in 2008. The timing of revenue is affected by both the length of time required to deploy a service and the length of the service contract.

Seasonality

     ZixCorp does not experience a material seasonal impact on sales or operations.

Geographic Information

     ZixCorp’s operations are primarily based in the United States, with approximately 12% of employees located in Canada. The Company does not operate in, or have dependencies on, any other foreign countries. ZixCorp revenues and orders to-date are almost entirely sourced in the U.S. and all significant corporate assets at December 31, 2007, were located in the U.S.

You should also refer to the other information set forth in this report, including our consolidated financial statements and the related notes.

      We have incurred significant operating losses in previous years and our PocketScript e-Prescribing service continues to use significant amounts of cash. We have incurred significant operating losses in previous years and we expect to incur operating losses in 2008. Our PocketScript e-Prescribing service operates in an emerging market and developing this business is costly. Our e-Prescribing business has consumed a significant amount of cash since we entered the e-Prescribing business in mid-2003, and we expect the e-Prescribing business to consume cash (i.e., be cash flow negative) in 2008. Emerging-market businesses involve risks and uncertainties, and there are no assurances that we will be successful in our efforts to achieve profitability for this line of business.

     Our liquidity and capital resources remain limited. To date, our cash flow from operations has not been sufficient to fund our on-going operations and we have relied on equity and debt financings to fund our operations during the last few years. While the Company’s goal is to be cash flow positive overall, in the near term, there is no assurance this will occur. Consequently, there can be no assurance that our liquidity or capital resource position would allow us to continue to pursue our current business strategy, particularly our e-Prescribing line of business. As a result, without achieving growth in our business along the lines we have projected, we would have to alter our business plan or further augment our cash flow position through cost reduction measures, sales of assets, additional financings or a combination of these actions. There is no assurance that any of these actions would be possible or could be implemented on terms acceptable to the Company. Additionally, one or more of these actions would likely substantially diminish the value of our common stock.

      The market may not broadly accept our Email Encryption and PocketScript e-Prescribing services, which would prevent us from operating profitably. We must be able to achieve broad market acceptance for our Email Encryption and e-Prescribing solutions and services, at a price that provides an acceptable rate of return relative to our company-wide costs in order to operate profitably. We have not yet been able to do this. Our Email Encryption business segment has begun to yield positive cash flow from operations, but there are no assurances that it will continue to yield sufficient cash flow to overcome the negative cash flow from the e-Prescribing segment and our corporate overhead costs. As noted, our PocketScript e-Prescribing service operates in an emerging market. There is no assurance that this market will develop sufficiently to enable us to operate our PocketScript business profitably. We have been pursuing the e-prescribing business since mid-2003, and our pursuit of the business has consumed significant amounts of cash and the e-prescribing business is projected to continue to consume cash for the foreseeable future. See “ End-users of our PocketScript service may not continue to use the service” under risk factors below and “Item 7. Management’s Discussion and Analysis of Financial Conditions and Results of Operations, Liquidity and Capital Resources,” below .

      Failure to enter into additional or to maintain existing sponsorship agreements for our PocketScript e-Prescribing service and generate other revenue sources from our PocketScript service could harm our business. Our PocketScript business has incurred significant operating losses. Through December 31, 2007, significant orders for our PocketScript e-Prescribing service came from sponsorship agreements with healthcare payors. Under our payor-sponsorship business model, we deploy PocketScript to the end-user physician and provide the end-user physician a subscription to use the service in return for payments from the healthcare payor. These payments are in the form of guaranteed payments from the healthcare payor or contingent payments that are based on contractually specified performance metrics. In some cases, these contingent payments could represent a substantial portion of the revenue opportunity under the contract. The significant majority of all of the end-user physicians who are using the PocketScript service and for whom we are currently recognizing revenue are doing so under a subscription arrangement that has been paid for by a healthcare payor. If the healthcare payors fail to renew their sponsorships, there is no assurance that the physicians will pay to continue to use the PocketScript service. See “Item 7. Management’s Discussion and Analysis of Financial Conditions and Results of Operations, Liquidity and Capital Resources,” below .

     In addition, we obtain cash and revenue from prescription transaction fees from payors, pharmacy benefit managers and others with respect to the electronic prescriptions processed through our e-Prescribing service. Increasing our active physician user base and increasing prescription transaction and performance-based fees are critical to the success of our plan to achieve profitability in our e-Prescribing business. There can be no assurance that we will be able to do so.

     We will not achieve significant cash and revenues from our e-Prescribing service unless we sign follow-on orders from our existing healthcare payors, from whom a significant portion of our cash and revenues are received, or sign new sponsorship agreements with other payors, or generate significant revenue from contingent payments, or maintain and identify other revenue opportunities for our e-Prescribing service, such as add-on applications or prescription transaction fees, and/or new uses for the transaction data itself. There can be no assurance that the Company will be able to achieve all or any of these requirements. If we are not successful in these endeavors, we could be required to revise our business model, exit or reduce the scale of our e-Prescribing business, or raise additional capital.

      Physicians and other healthcare providers may fail to adopt our PocketScript service. Our PocketScript service is targeted to the emerging market for e-Prescribing which provides physicians the ability to use a handheld device to prescribe drugs and transmit prescriptions electronically to any retail pharmacy. Through the use of the handheld device, the physician is provided with real-time decision support at the point of care, such as insurance formulary and drug interactions, that would normally not be available in a paper prescription process. This enables the physician to leverage technology for better patient care. This is an emerging market, and the success of our PocketScript service is dependent, in large measure, on physicians changing the manner in which they write prescriptions. Our challenge is to make this new service attractive to physicians, and ultimately, profitable. To do so has required, and in the foreseeable future will require, us to invest significant amounts of cash and other resources. There is no assurance that enough paying users will ultimately be obtained to enable us to operate the PocketScript service profitably. If we are not successful in these endeavors, we could be required to revise our business model, exit or reduce the scale of our e-Prescribing business, or raise additional capital.

      End-users of our PocketScript service may not continue to use the service. The Company currently estimates approximately 10,000 to 12,000 active physician users (subscribers) of the e-Prescribing service are needed to cover its e-Prescribing fixed costs. As of December 31, 2007, the Company had approximately 3,300 such active prescribers of the service, as compared to approximately 2,800 such active prescribers as of December 31, 2006 (see “ The market may not broadly accept our Email Encryption and PocketScript e-Prescribing services, which would prevent us from operating profitably” and “Physicians and other healthcare providers may fail to adopt our PocketScript Service” in risk factors above ) . Not all users to whom the e-Prescribing service is deployed will become active users. Furthermore, the Company has experienced attrition in its base of active users. Thus, there is no assurance that the Company will be able to achieve a sufficient number of active users to build a successful e-Prescribing business. See “Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, Revenue Indicators — Backlog, Orders and Deployments.” If we are not successful in these endeavors, we could be required to revise our business model, exit or reduce the scale of our e-Prescribing business, or raise additional capital.

      Failure to significantly increase our base of PocketScript users or obtain significant prescription transaction fees, or other fees may result in failure to achieve the critical mass of physicians and revenue to build a successful business. We incur significant up-front costs in connection with initially establishing our PocketScript e-Prescribing service with the physician users. Under our current business model, third-party payors typically pay all or a majority of the variable costs of initially establishing our e-Prescribing service. Our plan is to obtain additional revenues in the form of recurring annual subscription fees to use our e-Prescribing service, either paid by the third-party payors or the physicians. In addition, we must obtain additional revenues from prescription transaction fees, or other fees to operate this line of business profitably. Increasing our physician user base and increasing prescription transaction fees, or generating other fees, are critical to the success of this plan.

     Some of the prescription transaction fees that we currently receive are from pharmacy benefit managers, which manage the prescription benefits for their health plan customers, and an electronic script aggregator, which receives scripts written by the physician user of our PocketScript e-Prescribing service and transmits them via electronic data interchange to retail pharmacies. Our contracts with some of these entities are short term, meaning that the other party could cancel the contract or require us to renegotiate the contract with less favorable terms and conditions. These unfavorable terms and conditions could increase our costs and could require us to revise our business model.

     In sum, there is no assurance as to whether we will be able to maintain, or whether and how quickly we will be able to increase our user base or prescription transaction fees or whether we will be able to generate other fees to such a level that would enable this line of business to operate profitably. If we are not successful in these endeavors, we could be required to revise our business model, exit or reduce the scale of our e-Prescribing business, or raise additional capital.

      Competition in our businesses is expected to increase, which could impair our prospects and cause our business to fail. Our Email Encryption Services are targeted to the email encryption market. As the public’s and governmental authorities’ awareness about the need for privacy and security of electronic communications has increased over the past few years, well-funded competitors have entered the market. Companies that compete with our Email Encryption Service include content management and secure delivery companies, such as Tumbleweed Communications Corp., and other secure delivery participants, such as Voltage Security, PostX (recently acquired by Cisco Systems Inc.), PGP Corporation, Certified Mail, Authentica, Secure Computing, RxNT, and Sigaba Corporation. In addition, we face competition from vendors of operating systems, networking hardware, network management solutions, security solutions and security software, many of which now, or may in the future, develop or bundle email encryption into their products. Some of these competing companies have substantial information technology security and email protection products and have greater financial resources. In summary, current email encryption customers could move to competitive solutions, which would harm our business.

     Our PocketScript e-Prescribing service applies the benefits of e-messaging to the medical prescription process by enabling providers to write and transmit prescriptions electronically directly to the pharmacy. Competition is expected to increase as this emerging market continues to develop and it becomes generally apparent that there are viable business models for commercial success in this market. Participants in the e-prescribing space include AllScripts Healthcare Solutions, Dr. First, Inc., InstantDX LLC., iScribe, Prematics and RxNT. Competition from these companies and from vendors in related areas, such as electronic medical records vendors — who generally include e-prescribing services as an element of their service offering — is expected to increase.  These competitors could have more financial, technical, and other resources than the Company.

     Companies that do not currently compete with ZixCorp or only compete with selected products or in selected markets could become competitors in the future on a larger scale. Companies such as GE Healthcare or McKesson Corporation would likely offer a broad portfolio of health information technologies for all or some of the pharmaceutical, pharmacy, healthcare provider and managed care markets. This bundled array of services and solutions could be attractive to our current and potential customers. Favorable regulatory developments could hasten the entrance of these competitors into the market, particularly the e-prescribing market. See “Regulatory Drivers for Market Growth” above. With considerable size and access to capital, they could become significant competitors.

     We may face increased competition as these competitors partner with others or develop new solution and service offerings to expand the functionality that they can offer to their customers. Our competitors may, over time, develop new technologies that are perceived as being more secure, effective or cost efficient than our own. These competitors could successfully garner a significant share of the market, to the exclusion of our company. Furthermore, increased competition could result in pricing pressures, reduced margins, or the failure of our business to achieve or maintain market acceptance, any one of which could materially harm our business .

      Our inability to successfully timely develop and introduce new Email Encryption and e-Prescribing services and related services and to implement technological changes could harm our business. The evolving nature of the Email Encryption and e-Prescribing businesses require us to continually develop and introduce new and related solutions and services and to improve the performance, features and reliability of our existing solutions and services, particularly in response to competitive offerings.

     We have under development new functionality for our Email Encryption and e-Prescribing businesses. We may also introduce new services. The success of new or enhanced functionalities and services depends on several factors — primarily market acceptance. We may not succeed in developing and marketing new or enhanced functionalities and services that respond to competitive and technological developments and changing customer needs. This could materially harm our business.

      Future asset impairments could affect our financial results. As of December 31, 2007, we have $2,161,000 of goodwill on our balance sheet relating to the Email Encryption segment. Goodwill is evaluated at least on an annual basis or whenever there is a reason to question if the goodwill values are impaired. We also have $2,297,000 of property and other long-lived assets. The carrying value of these assets is evaluated whenever there is reason to question if the values are impaired. Future events could impact the valuation of goodwill and long-lived assets, which could require us to recognize a non-cash charge to earnings. It is possible that we may incur further charges for other asset impairments in the future as we evaluate the prospects of our various lines of business. Any such charges could materially affect our financial results.

      Capacity limits on our technology and network hardware and software may be difficult to project, and we may not be able to expand and/or upgrade our systems to meet increased use, which would result in reduced revenues. While we have ample through-put capacity to handle our customers’ requirements for the medium term, at some point if we achieve greater market penetration we may be required to materially expand and/or upgrade our technology and network hardware and software. We may not be able to accurately project the rate of increase in usage of our network, particularly since we have significantly expanded our potential customer base by the growing use of our PocketScript service. In addition, we may not be able to expand and/or upgrade our systems and network hardware and software capabilities in a timely manner to accommodate increased traffic on our network. If we do not appropriately expand and/or upgrade our systems and network hardware and software in a timely fashion, we may lose customers and revenues.

      Security interruptions to our data centers could disrupt our business, and any security breaches could expose us to liability and negatively impact customer demand for our solutions and services. Our business depends on the uninterrupted operation of our data centers — currently, our ZixData Center located in Dallas, Texas; and the Austin, Texas data center used for fail-over and business continuity services. We must protect these centers from loss, damage or interruption caused by fire, power loss, telecommunications failure or other events beyond our control. We carry limited insurance coverage to compensate us for losses that may occur as a result of any of these events. Any damage or failure that causes interruptions in our data centers’ operations could result in loss of or delay in revenues, failure to achieve market acceptance, diversion of development resources, injury to our reputation, litigation claims, increased insurance costs or increased service and warranty costs. This could materially harm our business, financial condition and results of operations.

     In addition, our ability to provide our services and to support the Email Encryption and e-Prescribing services depends on the efficient operation of the Internet connections between customers and our data centers. We depend on Internet service providers for these connections. These providers have experienced periodic operational problems or outages in the past. Any of these problems or outages could adversely affect customer satisfaction. We do not carry insurance to compensate us for losses that may occur as a result of any of these events.

     Furthermore, it is critical that our facilities and infrastructure remain secure and the market perceives them to be secure. Despite our implementation of network security measures, our infrastructure may be vulnerable to physical break-ins, computer viruses, attacks by hackers and similar disruptions. In addition, we are vulnerable to coordinated attempts to overload our systems with data, resulting in denial or reduction of service to some or all of our users for a period of time. We do not carry insurance to compensate us for losses that may occur as a result of any of these events.

     Secure messages sent through our ZixPort and ZixMessage Center messaging portals, in connection with the operation of our Email Encryption Service, include personal healthcare information as well as personal financial information. This information will reside, for a user-specified period of time, in our secure data center network. Also, individual prescription histories transmitted through our e-Prescribing system and other personally identifiable healthcare information may reside in our secure data center network indefinitely. Federal and state laws impose significant financial penalties for unauthorized disclosure of personal information. Exposure of this information, resulting from any physical or electronic break-ins or other security breaches or compromises of this information, could expose us to significant liability, and customers could be reluctant to use our services again.

      We may have to defend our rights in intellectual property that we use in our services, which could be disruptive and expensive to our business. We may have to defend our intellectual property rights or defend against claims that we are infringing the rights of others. Intellectual property litigation and controversies are disruptive and expensive. Infringement claims could require us to develop non-infringing services or enter into royalty or licensing arrangements. Royalty or licensing arrangements, if required, may not be obtainable on terms acceptable to us. Our business could be significantly harmed if we are not able to develop or license the necessary technology. Furthermore, it is possible that others may independently develop substantially equivalent intellectual property, thus enabling them to effectively compete against us.

      Defects or errors in our services could harm our business. We subject our solutions and services to quality assurance testing prior to release. Regardless of the quality assurance testing, any of our solutions could contain undetected defects or errors. In particular, our PocketScript system is used to transmit prescriptions. Defects or errors in our PocketScript system could result in inaccurate prescriptions being generated, which could result in injury or death to patients. Undetected defects or errors could result in loss of or delay in revenues, failure to achieve market acceptance, diversion of development resources, injury to our reputation, litigation claims, increased insurance costs, or increased service and warranty costs. Any one of these could prevent us from implementing our business model and achieving the revenues we need to operate profitably.

      Public key cryptography technology is subject to risks. Our Email Encryption Service and the e-Prescribing service employ, and future solutions and services may employ, public key cryptography technology. With public key cryptography technology, a public key and a private key are used to encrypt and decrypt messages. The security afforded by this technology depends, in large measure, on the integrity of the private key, which is dependent, in part, on the application of certain mathematical principles. The integrity of the private key is predicated on the assumption that it is difficult to mathematically derive the private key from the related public key. Should methods be developed that make it easier to derive the private key, the security of encryption services using public key cryptography technology would be reduced or eliminated and such services could become unmarketable. This could require us to make significant changes to our services, which could increase our costs, damage our reputation, or otherwise hurt our business. Moreover, from time-to-time there are public reports of the successful decryption of encrypted messages or encrypted information. This or related publicity could adversely affect public perception of the security afforded by public key cryptography technology, which could harm our business.

      We depend on key personnel. We depend on the performance of our senior management team — including our Chairman and CEO, Richard D. Spurr, and his direct reports and other key employees, particularly highly skilled technical personnel. Our success depends on our ability to attract, retain and motivate these individuals. There are no binding agreements with any of our employees that prevent them from leaving our company at any time. There is competition for these personnel. In addition, we do not maintain key person life insurance on any of our personnel. The loss of the services of any of our key employees or our failure to attract, retain and motivate key employees could harm our business.

      We rely on third parties. If critical services and products that we source from third parties were to no longer be made available to us or at a considerably higher price than we currently pay for them, and suitable alternatives could not be found, our business could be harmed.

     For certain elements of our service offerings, we sometimes rely on the products and services of third parties. In particular, we rely on third parties to supply the hand-held device used by the prescribing physician users of our e-Prescribing service. In 2006 and 2007, we were using primarily one supplier for this purpose. In the fourth quarter of 2006, we received an end-of-life product notice from this vendor. Consequently, we procured sufficient quantities of this device to accommodate 2007 forecasted deployments. The Company tested alternative devices in 2007 and has now chosen a new handheld device vendor for 2008. If these third parties, in general, elect to withhold their products or services or significantly raise their prices, we could be damaged financially in lower returns on sales and a lessening of competitive advantages if suitable alternatives could not be found in a reasonable period of time.

     Also, we have data interchange agreements with third parties, who source data and/or transport transactions relevant to the overall decision support and electronic prescribing capability offered by our PocketScript service. These third parties require us to adhere (“certify”) to their technical requirements. Our failure to maintain these technical certifications could hurt our competitiveness and impair our ability to secure new customers for our PocketScript service and maintain existing customers.

      We could be affected by government regulation. Exports of software solutions and services using encryption technology, such as our Email Encryption Service, are generally restricted by the U.S. government. Although we have obtained U.S. government approval to export our Email Encryption Service to almost all countries, the list of countries to which our solutions and services cannot be exported could be revised in the future. Furthermore, some countries impose restrictions on the use of encryption solutions and services, such as ours. Failure to obtain the required governmental approvals would preclude the sale or use of our solutions and services in international markets and, therefore, harm the Company’s ability to grow sales through expansion into international markets. Our largest OEM partner does sell and distribute our Email Encryption Service in overseas markets.

     There has been growing support from both inside and outside of the federal government for mandating e-prescribing of Medicare prescriptions, culminating with the introduction of the E-MEDS bill in the Senate and a corresponding bill in the House, which would have written such a mandate for e-prescribing Medicare prescriptions into law. E-MEDS bill has been rolled into the debate on a more permanent resolution for some of Medicare’s bigger issues that need to be revisited mid-year in 2008, which may or may not increase the chances of its ultimate passage. Even if the federal government does mandate e-prescribing for Medicare prescriptions, the Company believes any legislation mandating e-prescribing would have a phase-in period, so it is unlikely that a mandate would be in effect in 2008 or even 2009.  Therefore, while the existence of a mandate in the future would most likely lower the effort needed to sell physicians on the benefits of e-prescribing and would potentially increase the Company’s active and retention rates, there could be adverse effects, such as increased competition or a need for the Company to change the manner in which it recruits, deploys, and trains its physician users.

     The federal government has adopted regulations to create an exception to the prohibition on physicians’ referrals to healthcare entities with which they have financial relationships for certain electronic prescribing arrangements, to be codified at 42 C.F.R. §411.357(v), and an exception to the related federal healthcare anti-kickback rules for certain electronic prescribing arrangements, to be codified at 42 C.F.R. §1001.952(x). The purpose of the regulations is to encourage physicians to use electronic prescribing systems to create and deliver prescriptions to the pharmacy. The regulations seek to accomplish this purpose by creating certain safe harbors that are intended to encourage healthcare entities, such as health insurance companies and hospitals, to provide financial incentives to physicians to use electronic prescribing systems. These regulations, as they are interpreted and enforced over time, could provide other participants in the market a competitive advantage or could have currently unforeseen consequences that harm our business.

     Furthermore, boards of pharmacy in the various states in which our e-Prescribing business operates regulate the process by which physicians write prescriptions. While regulations in the states in which our e-Prescribing business currently operates generally permit the electronic writing of prescriptions, such regulations could be revised in the future. Moreover, regulations in states in which our e-Prescribing business does not currently operate may not be as favorable and may impede our ability to develop business in these states.

     Also, future state or federal regulation could mandate standards for the electronic writing of prescriptions or for the secure electronic transmittal of personal health information through the Internet that our technology and systems do not comply with, which would require us to modify our technology and systems. Many of these standards are currently being pilot tested in their initial form and may be subject to change, accelerated compliance restrictions or select re-implementations, based on resulting industry recommendations. The costs of compliance could be substantial.

      Our stock price may be volatile. The market price of our common stock has fluctuated significantly in the past and is likely to fluctuate in the future. Also, as of February 15, 2008, there was a reported short position in our common stock of 6,083,371 shares (approximately 9.7% of our outstanding number of shares), which may affect the volatility of our stock price.

      We have a significant amount of stock options and warrants outstanding and may issue additional equity securities in the future. Exercise of the outstanding options and warrants, and future issuances of other securities will dilute the ownership interests of existing shareholders. We have outstanding warrants and options, including options held by our employees, covering approximately 20 million shares of our common stock with exercise prices ranging from $1.21 to $57.60.

     The issuances of shares of common stock in respect of these warrants and options would result in a substantial voting dilution of our current shareholders. Any sales in the public market of the common stock issuable upon exercise of the warrants and options could adversely affect prevailing market prices of our common stock.

     In the future, we may determine to seek additional capital funding or to acquire additional businesses, which could involve the issuance of one or more types of equity securities, including convertible debt, common and convertible preferred stock, and warrants to acquire common or preferred stock. Such equity securities could be issued in public or private transactions, at or below the then-prevailing market price of our common stock. In addition, we motivate our employees and attract new employees by issuing shares of our common stock and options to purchase shares of our common stock. The interest of our existing shareholders may be diluted by any equity securities issued in capital funding financings or business acquisitions and would be diluted by any such future share issuances and stock option grants to employees.

     Finally, as a result of the anti-dilution provisions of certain of the warrants described above, we may be obligated to increase the number of shares that may be acquired upon exercise of our warrants and reduce the exercise price of such warrants. We might also be obligated to register with the SEC additional shares of common stock issuable to the warrant holders for public resale.

      The Company may be required to pay liquidated damages in the event one or more of the registration statements it has filed with the SEC for the benefit of third parties ceases to be effective. The Company has filed a number of registration statements with the SEC for the benefit of third parties. These registration statements permit the public resale of the Company’s common stock held by, or potentially issuable upon the exercise of options or warrants to, these parties. In some cases, the Company would be required to pay liquidated damages to the third parties if the Company fails to maintain the effectiveness of the relevant registration statement for the contractually required period of time. The amount of damages the Company would be required to pay could be substantial, as a percentage of the Company’s cash on hand, depending on when the registration statement ceased to be effective. (See, for example, Note 14 to the Company’s consolidated financial statements, regarding the potential payment of liquidated damages related to the April 5, 2006 Private Placement.)

     There are no assurances that we will be successful or that we will not encounter other, and even unanticipated, risks. We discuss other operating, financial or legal risks or uncertainties in our periodic filings with the SEC. We are, of course, also subject to general economic risks.

NOTE ON FORWARD-LOOKING STATEMENTS AND RISK FACTORS

     This document contains “forward-looking statements” (including the discussion appearing under the caption “Liquidity Summary” in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations, on page 43, as well as the discussion appearing under Note 1 located in NOTES TO CONSOLIDATED FINANCIAL STATEMENTS on page F-9) within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Act”) and Section 21E of the Exchange Act. All statements other than statements of historical fact are “forward-looking statements” for purposes of federal and state securities laws, including: any projections of future business, market share, earnings, revenues, cash receipts, or other financial items; any statements of the plans, strategies, and objectives of management for future operations; any statements concerning proposed new products, services, or developments; any statements regarding future economic conditions or performance; any statements of belief; and any statements of assumptions underlying any of the foregoing. Forward-looking statements may include the words “may,” “will,” “predict,” “project,” “forecast,” “plan,” “should,” “could,” “goal,” “estimate,” “intend,” “continue,” “believe,” “expect,” “outlook,” “anticipate,” “hope,” and other similar expressions. Such forward-looking statements may be contained in the “Risk Factors” section above, among other places.

     Although we believe that the expectations reflected in any of our forward-looking statements are reasonable, actual results could differ materially from those projected or assumed in any of our forward-looking statements. Our future financial condition and results of operations, as well as any forward-looking statements, are subject to change and to inherent risks and uncertainties, such as those disclosed in this document. We do not intend, and undertake no obligation, to update any forward-looking statement.

between the parties. The arbitration proceeding was held in January 2008, and the parties are awaiting the decision of the arbitrator. The claimant has requested damages approaching $1,000,000.  The Company has not concluded that it is probable that a loss will be sustained; and, even if a loss is probable, the amount of the loss cannot reasonably be estimated in the Company’s view. In light of the foregoing, under the applicable accounting guidance, no accrual for a potential loss is to be (and none has been) recorded in the Company’s consolidated financial statements for the twelve month period ending December 31, 2007.

     The Company is involved in other legal proceedings that arise in the ordinary course of business. In the opinion of management, the outcome of these other pending ordinary-course-of-business legal proceedings will not have a material adverse effect on the Company’s consolidated financial statements.

     The Company has severance agreements as of December 31, 2007, with certain employees that would require the Company to pay approximately $1,743,000 if all such employees separated from employment with the Company following a change of control, as defined in the severance agreements.

Item 6. Selected Financial Data

     The following selected financial data should be read in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” the consolidated financial statements and notes thereto included elsewhere herein. No cash dividends were declared in any of the five years shown below:

     The Company’s primary business strategy is the continued development and growth of its subscription businesses. The Company seeks to build and maintain reliable revenue growth by adding new customers while retaining a high percentage of existing customers. The subscription model requires large up front investment to establish the service, but over time the fixed set up costs are exceeded by the recurring subscription and transaction fees. The subscription business provides better returns after the setup costs are overcome as incremental costs to add new users are low relative to the incremental subscription revenue.

     As a secondary, but equally important, business strategy, the Company is balancing the cash produced by its more mature segment, Email Encryption, with the cash required to develop its emerging segment, e-Prescribing.

     Operationally, the success of the Company is primarily dependent upon the following key metrics:

	•		Rate of new subscriptions (termed “new first year orders”) for the Email Encryption Service;
	•		Renewal rates for the Email Encryption Service;
	•		Additional payor sponsorship of the e-Prescribing service to physicians by new or existing insurance payors;
	•		Successful adoption and usage of the e-Prescribing service by physicians;
	•		Retention of the users (physicians) of the e-Prescribing service as indicated by subscription renewals;
	•		Future transaction fees (or related fees) associated with the use of the e-Prescribing service; and
	•		Our ability to increase business volume with reasonable cost increases.

     Known trends regarding these key metrics and their implication on the Company’s current and future capital requirements are discussed throughout this MD&A.

     There are no assurances that the Company will be successful in its efforts to achieve success in these key metrics. The Company’s continued growth depends on the timely development and market acceptance of its products and services. The Company has incurred significant operating losses and used significant cash resources in prior years. The Company experienced improvement in its cash-flow performance in 2007 and 2006. The Company will continue to place a strong emphasis on actions to become cash flow breakeven in the near term, while balancing the needs for investments in its developing and emerging markets. Actions taken by the Company to achieve the goal of cash flow breakeven, such as near-term cost reductions, or decreased investments in certain areas of the business or business divestitures, might have intended or unintended short-term adverse effects on certain financial performance metrics for the Company. Despite its recent improved cash flow performance, the Company does expect to report further operating losses in its consolidated financial statements for 2008. See “Item 1A, Risk Factors” for more information on risk factors relevant to the Company’s operations and future prospects.

Critical Accounting Policies and Estimates

     The preparation of financial statements and related disclosures in accordance with accounting principles generally accepted in the United States requires the Company’s management to make estimates and assumptions that affect the amounts reported in the Company’s consolidated financial statements and accompanying notes. Actual results could differ from these estimates and assumptions. Critical accounting policies and estimates are defined as those that are both most important to the portrayal of the Company’s financial condition and results and require management’s most subjective judgments. The Company’s most critical accounting policies and estimates are described below.

      Inventory —The Company’s inventory consists mainly of the costs of handheld devices and related networking hardware for e-Prescribing and is reported as a component of Prepaid and Other Current Assets in the Company’s consolidated balance sheet. The inventory is valued at average purchase price and is reviewed quarterly for potential adjustments resulting from lower of cost or market valuations or obsolescence. As a general practice, the Company maintains a 60 to 90 day supply of inventory. However, in late 2006, the Company received an end-of-life product notice from its handheld device vendor. As a result, the Company procured additional quantities of handheld devices sufficient to accommodate the 2007 forecasted e-Prescribing deployments. With the supply of handheld devices resolved as of December 31, 2007, inventory levels had returned to normal maintenance levels of 60 to 90 days supply.

      Property and Equipment, Long-Lived and Other Intangible Assets, Depreciation and Amortization — The accounting policies and estimates relating to the property and equipment, long-lived and other intangible assets, depreciation and amortization are considered critical because of the significant impact that impairment, obsolescence, or change in an asset’s useful life could have on the Company’s operating results.

     Property and equipment are recorded at cost and depreciated or amortized using the straight-line method over their estimated useful lives as follows: computer and office equipment and software — three years; leasehold improvements — the shorter of five years or the lease term; and furniture and fixtures — five years. Intangible assets are amortized using the straight-line method over their estimated useful lives of three years.

     The Company’s long-lived assets subject to amortization and depreciation are comprised of identified intangible assets and property and equipment aggregating $2,297,000 or 12% of total assets at December 31, 2007. Property and equipment and intangible assets are reviewed for impairment when certain triggering events occur where there is reason to believe that the carrying value may not be recoverable based on expected undiscounted cash flows attributable to such assets. There were no such impairments in 2007. The amount of a potential impairment is determined by comparing the carrying amount of an asset to either the value determined from a projected discounted cash flow method, using a discount rate that is considered to be commensurate with the risk inherent in the Company’s current business model or the estimated fair market value. Assumptions are made with respect to future net cash flows expected to be generated by the related asset. An impairment charge would be recorded for an amount by which the carrying value of the asset exceeded the discounted projected net cash flows or estimated fair market value. Also, even where a current impairment charge is not necessary, the remaining useful lives are evaluated.

     During the first quarter of 2005, the Company evaluated the estimated useful lives of the intangible assets relating to the MyDocOnline acquisition and concluded that the lives for developed technology and customer relationships should be reduced to three years from five years and four years, respectively. This change in estimate was accounted for prospectively beginning January 1, 2005. In 2006, the Company recorded $125,000 of impairment charges on fixed assets that were not being utilized and had no perceived future value. In 2007, the Company recorded no impairment charges.

      Goodwill — Goodwill, totaling $2,161,000 or 11% of total assets at December 31, 2007 and 2006, represents the remaining cost in excess of fair value of net assets acquired in the September 2003 acquisition of Elron Software.

     In accordance with SFAS No. 142, Goodwill and Other Intangible Assets , goodwill is not being amortized; however, the Company evaluates its goodwill for impairment annually in the fourth quarter or when there is reason to believe that the value has been diminished or impaired. Evaluations for possible impairment are based upon a comparison of the estimated fair value of the reporting unit to which the goodwill has been assigned to the sum of the carrying value of the assets and liabilities of that unit including the assigned goodwill value. The fair values used in this evaluation are estimated based on the Company’s market capitalization, which is based on the outstanding stock and market price of the stock. Impairment is deemed to exist if the net book value of the unit exceeds its estimated fair value.

     The sale of the Message Inspector and Web Inspector products in the first quarter of 2005, which were a significant part of the Elron acquisition, caused the Company to evaluate the goodwill assigned to the eSecure reporting unit. As a result, the Company reduced goodwill in the first quarter of 2005 by $2,161,000 as part of the carrying value of the net assets related to that transaction. This represented 50% of the acquired goodwill from the Elron acquisition. The sale of the Dr. Chart product in September 2005 caused the Company to evaluate the goodwill associated with the purchase of MyDocOnline, of which Dr. Chart was a significant portion. As a result, the Company included in the carrying amount of assets sold in the Dr. Chart sale, the entire goodwill balance of $4,797,000 associated with the acquisition of MyDocOnline. See Note 6 to the consolidated financial statements for additional disclosure of these transactions.

     Future changes made to the current estimates or assumptions, including such factors as order volumes and price levels, life spans of purchased technology, continuity of acquired customers, alternative uses for property and equipment and levels of operating expenses, could result in an unanticipated impairment charge from the write-down of the Company’s long-lived assets or goodwill.

      Deferred Tax Assets — Deferred tax assets are recognized if it is “more likely than not” that the subject net operating loss carry-forwards and unused tax credits will be realized on future federal income tax returns. At December 31, 2007, the Company continued to provide a full valuation allowance against accumulated U.S. deferred tax assets of $112,995,000, reflecting the Company’s historical losses and the uncertainty of future taxable income. If the Company begins to generate U.S. taxable income in a future period or if the facts and circumstances on which its estimates and assumptions are based were to change, thereby impacting the likelihood of realizing the deferred tax assets, judgment would have to be applied in determining the amount of valuation allowance no longer required. Reversal of all or a part of this valuation allowance could have a significant positive impact on operating results in the period that it becomes more likely than not that certain of the Company’s deferred tax assets will be realized.

      Revenue Recognition — The Company recognizes revenue in accordance with accounting principles generally accepted in the United States of America, as promulgated by Statement of Position (“SOP”) 97-2, Software Revenue Recognition, SOP 98-9, Modification of SOP 97-2, Software Revenue Recognition, With respect to Certain Transactions, EITF Abstract No. 00-21, Revenue Arrangements with Multiple Deliverables, and Securities and Exchange Commission Staff Accounting Bulletin No. 104, Revenue Recognition in Financial Statements, and other related pronouncements. Accounting for revenue is complex due to the long-term and often multiple element nature of ZixCorp’s contracts with customers, and the potential for incorrect application of accounting guidance requires that revenue recognition be considered a critical accounting policy.

     The Company develops, markets, licenses and supports electronic information protection services. The Company’s services can be placed into several key revenue categories where each category has similar revenue recognition traits: Email Encryption subscription-based service, e-Prescribing service, various transaction fees and related professional services. A majority of the revenues generated by the Company are through direct sales; however, for the Email Encryption Service the Company employs a network of distributors and resellers. Under all product categories and distribution models, the Company recognizes revenue after all of the following occur: persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the price is fixed and determinable, and collectability is reasonably assured. In the event the arrangement has multiple elements with delivered and undelivered elements, revenue for the delivered elements are recognized under the residual method only when vendor-specific objective evidence of fair value (VSOE) exists to allocate the fair value of the total fees to the undelivered elements of the arrangement. Occasionally, when ZixCorp is engaged in a complex product deployment, customer acceptance may have to occur before the transaction is considered complete. In this situation no revenue is recognized until the customer accepts the product. Discounts provided to customers are recorded as reductions in revenue.

     The Email Encryption Service is a subscription-based service. In the first nine months of 2005, subscription-based services also included Dr. Chart, which was sold by the Company in September 2005 (see Note 6 to the consolidated financial statements). Providing these services includes delivering subscribed-for-software and providing secure electronic communications and customer support throughout the subscription period. In the case of ZixVPM, typically, as part of the service, an appliance with pre-installed software is installed at the customer site at the beginning of the subscription period. In a subscription service, the customer does not own a perpetual right to a software license, but is instead granted the use of the subscribed-for-software during the period of the service subscription. Subscriptions are generally multiple-year contracts that are irrevocable and non-refundable in nature and require annual, up-front payments. The subscription period begins on the date specified by the parties or when the service is fully functional for the customer which is consequently deemed to be the date of acceptance. Revenues from subscription services are recorded as service revenue as the services are rendered from the date of acceptance over the subscription period. Subscription fees received from customers in advance are recorded as deferred revenue and recognized as revenue ratably over the subscription period.

     The e-Prescribing service arrangements contain multiple deliverables, including both hardware and services. Due to the lack of VSOE, these elements are combined into a single unit of accounting and, similar to Email Encryption, recognized as service revenue ratably over the longer of the subscription term or expected renewal period. Revenue recognition begins upon installation of the required hardware and commencement of service.

     Prior to the third quarter 2005, the Company did maintain VSOE for certain service elements of the e-Prescribing service. Accordingly, the residual value assigned to the PocketScript handheld device was recognized as revenue upon installation and the fair value of the undelivered services were recognized ratably over the period in which those services were delivered.

     Some of the Company’s services incorporate a transaction fee per event occurrence or when predetermined usage levels have been reached. These fees are recognized as revenue when the transaction occurs or when the predetermined usage levels have been achieved, and when the amounts are fixed and determinable.

     The Company does not offer stand alone services. Further, the Company’s services include various warranty provisions; however, warranty expense was not material to any period presented.

      Deferred Cost of Revenue — In accordance with the Company’s revenue recognition policy, the revenue associated with certain PocketScript deployments is being recognized ratably over the period the services are being delivered. To properly match direct costs and revenue, the Company defers the direct, incremental costs of each deployment expected to be recovered. These costs consist mainly of the cost of the handheld device, and are recorded as deferred cost of revenue. The deferred costs are then amortized into cost of revenue ratably over the period in which revenue is recognized. The deferred cost of revenue of $301,000 and $334,000 is included in other assets as of December 31, 2007 and 2006, respectively.

      Stock-based compensation — On January 1, 2006, the Company adopted SFAS 123(R), Share-Based Payment , and elected to use the modified prospective method along with the straight line amortization method for recognizing stock option compensation costs. For periods prior to January 1, 2006, the Company used the intrinsic value method to account for stock-based compensation plans under the provisions of Accounting Principles Board (“APB”) No. 25, Accounting for Stock Issued to Employees and related interpretations.

     SFAS 123(R) replaced the intrinsic value measurement objective in APB 25 and requires companies to measure the cost of employee services received in exchange for an award of equity instruments based on the fair value of the award on the date of the grant. The standard requires grant date fair value to be estimated using either an option-pricing model which is consistent with the terms of the award or a market observed price, if such a price exists. Such cost must be recognized over the period during which an employee is required to provide service in exchange for the award, i.e., “the requisite service period” (which is usually the vesting period). The standard also requires companies to estimate the number of instruments that will ultimately be earned, rather than accounting for forfeitures as they occur.

     The Company used the Black-Scholes Option Pricing Model (“BSOPM”) to determine the fair value of option grants made during 2007, 2006, and 2005. The Company estimated the average holding period of vested options to be two years from the vesting period (1.6 – 1.8 years) for options granted before 2006, but used the “simplified” method per SEC Staff Accounting Bulletin No. 107, Share Based Payment, to calculate the estimated life of options granted to employees subsequent to December 31, 2005. The expected stock price volatility was calculated by averaging the historical volatility of the Company’s common stock over a term equal to the expected life of the options. The following weighted average assumptions were applied in determining the fair value of options granted during the respective periods:

     The assumptions used in the BSOPM valuation are critical as a change in any given factor could have a material impact on the financial results of the Company.

     Prior to the adoption of SFAS 123(R), the Company applied Accounting Principles Board (“APB”) No. 25 to account for its stock-based awards. The following table details the affect on the Company’s net loss and loss per common share had compensation expense for employee stock-based awards been recorded in the twelve months ended December 31, 2005, based on the fair value method under SFAS 123(R):

With these incremental cash receipts, the Company elected to prepay the $1,600,000 promissory note mentioned immediately above and to prepay certain 2008 procurements totaling approximately $700,000.

Results of Operations

     Email Encryption and e-Prescribing are primarily subscription-based services. In 2005, the MI/WI products were primarily sold as perpetual licenses with annual maintenance and/or subscription contracts. Prior to the third quarter of 2005, e-Prescribing incorporated a separate hardware and installation element, and the Dr. Chart product and services represented either a subscription-based arrangement or a perpetual license sale. With the exception of perpetual software licenses (MI/WI products and occasionally the Dr. Chart product) and early stage e-Prescribing contracts, the Company has generally recognized revenue over the life of a related service contracts under Services Revenue. The shift towards mostly subscription based offerings in late 2005 led to the decline in hardware revenue, and the sale of the MI/WI product lines in the first quarter of 2005 led to the decline in software revenue.

     The Company believes that total revenue by product line provides a more meaningful examination of the Company’s revenue sources and trends:

      Email Encryption — The revenue increases of $3,888,000 (28%) and $4,087,000 (41%) in Email Encryption for 2007 and 2006, respectively, over the previous years’ revenue are due to the Company adding new subscribers to the service while renewing a high percentage of existing subscribers as their service contracts expired. Revenues are recognized as the service is provided and therefore the 2007 revenue increase of $3,888,000 is primarily due to New First Year Orders (“NFYO’s”) generated in 2006. The Company’s additions to the subscriber base is best measured by NFYO’s, which are defined as the portion of new orders that are expected to be recognized into revenue in the first twelve months of the contract. In 2007 and 2006 the new first-year orders were approximately $5,500,000 and $4,700,000, respectively. As the Company has continued to add new customers, the renewal rate of existing customers has consistently remained above 95% for the periods shown which, in turn, has led to the Company’s yearly revenue growth.

     The recurring nature of the subscription model makes revenue rise in a predictable manner assuming continued new additions to the subscription base and adequate subscription renewal rates. Adding to the predictability is the Company’s go-to-market model of selling primarily three-year subscription contracts with the fees paid annually at the inception of each year of service. The Company’s list pricing for Email Encryption has remained generally consistent in 2007 when compared with 2006 and the Company has experienced relatively consistent discount percentages off the list price in those periods. The Company did announce a slight price increase for its ZixVPM, ZixVPM Alliance and ZixVPM Corporate services effective in January 2008. In general, customers that are due for renewal are renewed at a price equal to or greater than their previous service period.

      e-Prescribing — e-Prescribing revenues increased $1,868,000 (44%) in 2007 compared to 2006. This increase was primarily driven by an increase in renewal revenues of $918,000 (119%) in 2007 compared to 2006. Also driving improvement were transaction/usage-based fees which increased by $725,000 (63%) when compared to 2006. Additionally, revenue recognized on deployments to new PocketScript users increased $191,000 (9%) when compared to 2006. The total new users of the service for which revenue could be recognized decreased from approximately 2,400 in 2006 to approximately 2,000 in 2007 due to lack of contracts for new payor sponsorships and/or expansion programs initiated in 2007 by existing payors. However, this decrease in new billable users was offset in part by an increase in the average price per billable deployment of approximately 20%. Revenues relating to one time projects increased $50,000 (47%) in 2007 when compared to 2006. These one-time projects are not expected to be repeated on a regular basis and usually relate to special projects and requests made by customers. Other e-Prescribing revenue declined $16,000 (-17%) in 2007 compared to 2006.

     One customer accounted for $489,000 of the increase in transaction/usage-based fees and this customer is only contractually bound to continue paying the majority of these fees through 2007. The Company is working with the customer to continue these fees and, if not successful in doing so, it will endeavor to replace them with new contracts with existing and/or new customers, but it is not known if the Company will be successful in its efforts.

     The 2006 revenues in e-Prescribing increased by $1,283,000 (43%) when compared to 2005. This increase was mainly driven by transaction/usage-based fees which increased by $936,000 (439%) when compared to 2005. Additionally, revenue recognized on deployments to new PocketScript users, service renewals, and one time projects increased $351,000 (13%) when compared to 2005.

      Divested Products: The decline in revenues from the Web Inspector and Message Inspector products and the Dr. Chart products resulted from the divestitures of these products in March 2005 and September 2005, respectively. See Note 6 to the consolidated financial statements.

      Revenue Outlook: The Company’s future revenue growth in 2008 is primarily expected to come from continued success in the Email Encryption business, while targeting the healthcare, finance, insurance and government sectors. Email Encryption revenue growth is expected to mirror the 2007 performance rate of approximately 30%. While the Company has experienced a greater than 40% revenue increase in e-Prescribing for both 2007 and 2006, continued growth in this segment is almost entirely dependent on the Company securing new (or expanding existing) payor sponsorship contracts in the first six months of calendar year 2008. In 2007, the Company secured commitments with payors to deploy significantly fewer new prescribers than in previous years. Consequently, the Company’s backlog of yet-to-be-deployed new prescribers at the end of 2007 was significantly lower than the backlog at the end of 2006. Thus, absent securing contracts for a sufficient number of new sponsored prescribers in the first half of 2008, the Company will expect revenue from its e-Prescribing services to decline in 2008. Despite the decline in yet-to-be-deployed new subscribers, the Company believes that there is high interest on the part of (a) currently contracted payors in expanding their existing programs, and (b) prospective payors who are in the exploratory phases of committing to executing a new sponsorship contract. However, there can be no assurance the Company will be successful in expanding its current payor programs or contracting with new payors.

Backlog, Orders, and Deployments

      Company-wide backlog — The Company’s end-user order backlog is comprised of contractually bound agreements that the Company expects to fully amortize into revenue. As of December 31, 2007, the backlog is comprised of the following elements: $16,103,000 of deferred revenue that has been billed and paid, $3,328,000 billed but unpaid, and approximately $12,361,000 of unbilled contracts. The backlog can also be divided by product, of which $28,314,000 is for Email Encryption and $3,478,000 is for e-Prescribing.

     The backlog is recognized into revenue as the services are performed. Approximately 45% of the total backlog is expected to be recognized as revenue during the next twelve months. The timing of revenue is affected by both the length of time required to deploy a service and the length of the service contract.

     The Company’s future revenue growth from Email Encryption, beyond what is scheduled to be recognized from the backlog, is determined by total new orders for Email Encryption, which are made up of renewals from existing customers (renewal of usage by previously existing users with previously in-use products) whose contracts are expiring and new orders (new orders from new users in existing customer accounts, new products in existing accounts and brand new customers). To forecast the near term impact of these new orders (orders from new users in existing customer accounts, new products in existing accounts and brand new customers), we use the metric we call New First Year Orders (NFYO’s), which only looks at the first 12 months of a new contract (contracts are typically 3 years in length) to forecast the near term impact on revenue. For e-Prescribing the future revenue will be determined by securing additional payor sponsorships, increasing adoption and utilization by the physicians, renewing existing prescribers as they expire, and developing additional transaction-based fees.

      Email Encryption Orders — Total order input for Email Encryption in 2007 was $24,160,000 compared with $17,457,000 in 2006. Total orders include customer orders that management separates into three components for measurement purposes: contract renewals, new first year orders, and in the case of new multi-year contracts, the years beyond the first year of service. The new first-year orders were $5,514,000 in 2007 and $4,665,000 in 2006.

     The following table provides the relevant trend of new first-year orders:

     The 2007 Email Encryption contract renewal rate was 99% on a contract value basis ($6,210,000), which will lead to continued revenue growth. Beginning in 2007, the Company moved to a new metric for measuring its customer renewal rate for Email Encryption. Previously, the Company used a metric that represented the percentage of the number of gateway and portal customer accounts that had renewed. While this “per-capita” metric was very useful as a measurement of overall customer satisfaction with our services, it did not draw any distinctions between our largest and smallest customers. The Company’s new renewal metric is based on the twelve month dollar value of bookings versus the previous twelve month bookings value for the same set of customers rather than the “per-capita” number of customer accounts. As with the previous method of measurement, this metric will represent bookings from our gateway and portal customers. In general, contracts are renewed at a price equal to or greater than their previous service period. However, there are no assurances that potential increased competition in this market or other factors will not result in future price erosion. Such a price erosion, should it occur, could have a dampening effect on the Company’s renewal-related revenue.

     The Company continues to experience a high percentage of customers who choose to subscribe to the Email Encryption Service for a three-year term versus a one-year term. The Company expects this preference by a high percentage of its customers for a longer contract term to continue in 2008, as the Company has priced its services in a manner that encourages longer-term contractual commitments from customers. The Company’s list pricing for Email Encryption has remained generally consistent in 2007 when compared to 2006 and the Company has experienced relatively consistent discount percentages off the list price in those periods. The Company did announce a slight price increase for its ZixVPM, ZixVPM Alliance and ZixVPM Corporate services effective in January 2008. However, there are no assurances that potential increased competition in this market or other factors will not result in future price erosion. Such a price erosion, should it occur, could have a dampening effect on the Customers new first-year orders.

     While ZixCorp continues to foresee steady demand from the healthcare sector, the industry is beginning to mature- consequently, the Company has increased its efforts to diversify its business into additional sectors. The Company’s continued focus on markets such as financial services, insurance and government along with the increased use of indirect distribution channels should enable it to sustain or increase the new first year order rate in 2008.

      e-Prescribing — In e-Prescribing, the Company builds the subscriber base by contracting with health insurance companies (payors) to sponsor physicians in their network to receive the e-Prescribing equipment and service free of charge for the first year. As of December 31, 2007, the Company had active contracts with eight such payors. The current list prices for initial and subsequent annual renewal periods for the e-Prescribing service are $2,000 and $600, respectively. The Company has secured contracts at the list price and has also succeeded in receiving more beneficial payment terms than in previous years.

     In 2007, the Company secured sponsorships for new deployments of approximately 280 new prescribers which compares to sponsorships for new deployments of approximately 2,850 new subscribers in 2006. Although new sponsorships, in number, were disappointing, we added one very significant new sponsor, United Healthcare. We believe that a successful pilot with this significant new customer could lead to a broad-based, national rollout of our e-Prescribing service. Future revenue growth of the e-Prescribing segment is dependent on expanding current payor sponsorships such as the one with United Healthcare, as well as securing additional payor contracts, achieving and increasing adoption and utilization by the sponsored physicians, renewing service contracts for active physicians at the end of their sponsorship, and developing additional transaction-based fees.

     The deployments of subscribers and the number of active users are indicators of future revenue. In 2007, the Company deployed approximately 1,950 users compared with approximately 2,250 in 2006. The Company has approximately 280 sponsored, but not yet deployed, prescribers in deployment backlog as of December 31, 2007. The number of active users is also important as a measurement of the user base. Active users measures the number of subscribers who are effectively using the e-Prescribing service at a meaningful level in order to generate transaction revenues, and as an indicator of retention and future renewal opportunities. The Company has a twofold objective in deploying new users: first, to ensure they become regular users of the service (active) and second, to ensure that services are renewed (retention). As of December 31, 2007, the Company had approximately 3,300 active prescribers using the service, compared with approximately 2,800 active prescribers at December 31, 2006. Based on current trends, the Company believes that 60% to 70% of the users deployed in 2007 will ultimately become active users. The Company is continuing its efforts to increase the percentage of active users that result from new deployments.

     Sponsorship contracts typically specify that individual physicians using the e-Prescribing service assume responsibility for renewing the service after the first year. However, Blue Cross and Blue Shield of Massachusetts has renewed the service for its qualified active users for a fourth year; and six of the Company’s other seven payors have also agreed to pay for some or all of the subscription fee for its active users. (The sponsorship associated with the remaining payor, United Healthcare Services, Inc., was signed in the second half of 2007, and its deployed users are not yet due to renew.) For those users that do not meet the required activity level for continued sponsorship by their particular payor, the Company attempts to contract directly with the individual user or medical practice.

     The total transaction and usage-based fees recognized as revenue during 2007 were $1,875,000 compared to $1,145,000 in 2006. The Company has a contract with a payor sponsor that provides for a shared savings arrangement measured by improvement in physician-user prescribing behavior. The Company has also signed four contracts with transaction-based fees or the equivalent with existing and new healthcare payors. While increasing the number of active users should increase the prescriptions written and thus increase the potential for transaction fees under current agreements, substantial revenue increases from transaction fees will require additional transaction-based fees from new and existing customers. The Company is seeking such agreements with interested parties. The Company believes that the source of new transaction related fees will come from payors — both existing and new payors that sponsor e-prescribing programs, as well as other payors that have insured members visiting doctors that already use the PocketScript service via a sponsorship arrangement from another competing payor. In most cases, there are multiple payors in each market and the Company believes that those additional non-sponsorship payors may be potential sources for supplemental fees in return for certain services such as formulary display, drug-to-drug interaction checking and reporting.

     Finally, possible sources for other transaction fees include parties who could benefit from a real-time, electronic connectivity with PocketScript users. For example, the Company is piloting a disease management program with one of its payors which alerts physicians through the e-Prescribing service that a patient may be eligible for enrollment. In addition, the Company currently has contracts under which it earns fees for sending prescriptions electronically to the pharmacies and for certain transactions involving prescriptions related to pharmacy benefit managers (PBM).

     The number of prescriptions written using the PocketScript service and thus transmitted through the ZixData Center has been growing on a year-over-year basis. In 2007, the Company transacted approximately 7,400,000 prescriptions compared to 5,300,000 prescriptions in 2006. The Company is investing greater sales effort and post-deployment attention to maximizing utilization in order to maximize future revenue potential both through renewals and transaction fees.

     The Company believes that the payor sponsorship model is the right one to scale and accelerate adoption and usage and to lay the foundation for secure, interoperable healthcare information access and decision support. However, continued growth in this segment will require additional payor sponsors or a change in the market demand model and increased revenues from transaction fees (or the equivalent).

     The $1,686,000 improvement in cost of revenues for the twelve months ended December 31, 2007, compared to the twelve months ended December 31, 2006, consists of a $1,448,000 decrease in non-cash expenses and a $238,000 decrease in cash expenses. The reduction in non-cash expenses consists of depreciation costs of $857,000; amortization expense of $512,000 due to intangible assets becoming fully amortized; stock-based compensation expense decrease of $41,000 and other miscellaneous non-cash expense decrease of $38,000. Depreciation expense decreased due to a change in allocation of expense between cost of revenues; research and development; and selling, general and administrative expenses. In 2007, $184,000 of expense was allocated to research and development and $77,000 allocated to selling, general and administrative expenses from cost of revenues, whereas no expense was allocated in 2006. The remaining decrease in depreciation expense is due principally to certain assets becoming fully depreciated between periods. The decrease in cash expenses consists principally of the following cost reductions: electronic data processing costs of $105,000; occupancy costs of $233,000; travel expenses of $138,000 and other sundry costs of $79,000, partially offset by a slight increase in people costs of $208,000 and consulting costs of $109,000. Travel, occupancy and electronic data processing costs are lower due to cost reduction processes initiated in 2005 and 2006. Of the total occupancy costs reduction, approximately $389,000 in decreases resulted from lower costs of internet connectivity, partially offset by an increase of $191,000 due to a change in the allocation of the Company’s IT services, commencing in July 2006 between cost of revenues; research and development; and selling, general and administrative expenses.

     The Company’s cost of revenues was $12,552,000 for the twelve-month period ended December 31, 2006, compared to $14,194,000 for the same period in 2005. The decrease of $1,642,000 consists primarily of a $1,012,000 net reduction in personnel costs, $177,000 reduction in computer-related expendables, maintenance, support and software licenses, $381,000 reduction in depreciation expense, $386,000 reduction in intangibles amortization expenses and reduced travel-related expenses of $112,000, partially offset by an increase in occupancy costs of $224,000, stock-based compensation costs of $177,000 and other sundry costs of $25,000. The Company’s occupancy costs are allocated based on headcount associated with cost of revenues, research and development expenses and selling, general and administrative expenses. The Company’s total occupancy costs have decreased between the comparable years of 2006 and 2005 due to the combined effects of the 2006 reduction in workforce and the 2005 divestitures of the MI/WI and Dr. Chart product lines. However, the headcount reductions in cost of revenues resulting from these events have been proportionally less than those reductions in the research & development and selling, general and administrative expense classifications. This disproportionate reduction in headcount has resulted in a higher allocation of occupancy costs to cost of revenues. The increase in stock-based compensation costs is due to the 2006 adoption of SFAS 123(R) (see Note 4 to the consolidated financial statements).

     The reductions in personnel costs and travel expenses between years 2006 and 2005 were primarily due to the 2006 workforce reduction and 2005 product line divestitures. The reduction in depreciation expense is due to the 2005 divestitures as well, the effects of previously recorded impairments on certain fixed assets and other certain fixed assets becoming fully depreciated. The reduced amortization expense of intangible assets resulted from the 2005 write-down of certain intangible assets also related to the divestitures of the MI/WI and Dr. Chart product lines.

      Email Encryption — Email Encryption’s cost of revenues is comprised of costs related to operating and maintaining the ZixData Center, a field deployment team, customer service and support and the amortization of Company-owned, customer-based computer appliances. For Email Encryption, a significant portion of the total cost of revenues relates to the ZixData Center, which is currently not fully utilized. Accordingly, cost of revenues is relatively fixed in nature and is expected to grow at a slower pace than revenue. Email Encryption has shown the ability to grow revenues, while leaving cost of revenues flat or only marginally increasing as more efficient methods of product delivery and service have been implemented. For example, the Email Encryption revenues for year 2007 have increased $3,888,000, or 28%, when compared to year 2006, but the cost of revenues has actually decreased as indicated above.

      e-Prescribing — e-Prescribing’s cost of revenues is comprised of costs related to operating and maintaining the ZixData Center, a field prescriber recruiting team, a field deployment team, customer service and support, training and e-Prescribing device costs. In e-Prescribing, a greater proportion of total cost of revenues relates to the field deployment and device costs. These are more variable in nature than the ZixData Center and accordingly, e-Prescribing costs are more closely correlated with demand. The $680,000 decrease in cost of revenues for total year 2007 compared to total year 2006 reflects a reduction of approximately $630,000 in fixed costs and a reduction in variable costs of $50,000, which is primarily the cost of the handheld device. The reduction in fixed costs is due principally to intangible assets becoming fully amortized between years previously discussed. The reduction in variable costs is primarily due to a decrease in deployments. The new billable deployments in 2007 were approximately 1,950 compared to 2,250 in 2006. Because e-Prescribing costs of revenues have a greater variable component, a decrease or increase in e-Prescribing demand, as measured by revenue and deployments, is expected to result in a corresponding decrease or increase in the related cost of revenues.

      Divested Products — MI/WI and Dr. Chart product lines were offered for sale in 2005. MI/WI was divested on March 31, 2005, and Dr. Chart was divested in September 2005 (see Note 6 to the consolidated financial statements). Therefore, the Company experienced cost of revenues for these products in 2005, but not in 2006.

Research and Development Expenses

     Research and development expenses decreased 13% in 2007 versus a 7% decrease in 2006. The following table sets forth a year-over-year comparison of the Company’s research and development expenses:

     The $763,000 improvement in 2007 versus 2006 is made up of a decrease in cash expenses of approximately $838,000, partially offset by an increase in non-cash expenses of $75,000. The decrease in cash expenses consisted of $948,000 reduction for people costs which reflected headcount reductions principally in the PocketScript area of the business. This decrease was partially offset by increases in non-people cash expenses, principally for costs associated with electronic data processing. Those expenses consisted of miscellaneous hardware and related components and software license fees paid to third-party service providers of $96,000 and other sundry expenses of $14,000. The increase in non-cash expenses consists of depreciation expense of $121,000, which is due principally to a higher percentage of total depreciation expense being allocated to research and development expense in 2007 than 2006 totaling approximately $184,000, partially offset by other certain fixed assets becoming fully depreciated and decreases in non-cash commissions and stock-based compensation expense.

     The $435,000 decrease from 2006 to 2005 consists primarily of $385,000 for headcount reductions due principally to the 2006 reduction in workforce, $95,000 for reduced occupancy costs, $85,000 principally for reduced depreciation costs as a result of certain fixed assets becoming fully depreciated, partially offset by an increase in stock-based compensation costs of $127,000 resulting from the Company adopting SFAS 123(R) (see Note 4 to the consolidated financial statements).

     The Company expects research and development expenses in 2008 to increase slightly over the 2007 expense levels as a result of a customer contract that requires additional or new features to the e-Prescribing service for that customer, as well as an overall increase in research and development activities planned for both product lines.

Selling, General and Administrative Expenses

     Selling, general and administration expenses decreased 23% for 2007 when compared to 2006. The general trend of reduced selling, general and administrative expenses began in 2005 and continued in 2006 and 2007 as the Company consolidated various marketing initiatives in 2005 from previously acquired companies, divested previously acquired companies, and concentrated its efforts to reduce overall company spending. These efforts to reduce overall company spending included the 2006 reduction in workforce and actions taken to lower non-people costs. These reductions have been offset in part by the addition of share-based compensation costs related to employee and non-employee stock options in 2006 (see Note 4 to the consolidated financial statements). The general trend of reduced expenses throughout 2005, 2006 and the early part of 2007 was a product of a number of cost reduction initiatives executed by the Company. For 2008, the Company believes selling, general and administrative expenses will increase slightly due to general inflationary pressures on cash expenses and increases in non-cash expenses, principally stock-based compensation.

     The following table sets forth a year-over-year comparison of the Company’s selling, general and administrative expenses:

     The $5,227,000 improvement in selling, general, and administrative expense in 2007 versus 2006 is made up of $3,669,000 of cash expenses and $1,558,000 in non-cash expenses. The $3,669,000 cash expense decrease was split between people costs and non-people costs of $2,542,000 and $1,127,000, respectively. People costs decreased due to lower headcount. The significant contributors in lower non-people cash expenses were a reduction in occupancy costs of $400,000, primarily due to both a change in allocation for IT services (whereby approximately $314,000 of previously unallocated expense was distributed in 2007 to the research and development and the cost of revenues categories), and also to a $134,000 improvement in telephone service costs; a reduction in professional fees of $358,000; a reduction in travel expenses of $332,000 due to reduced headcount; and a reduction in advertising and promotion of $333,000 due to budget cuts. The remaining decreases in non-people cash expense resulted from cost reductions spread across the following expense categories: bad debts, dues and licenses, electronic data processing costs, business insurance and stockholder expense. These decreases in non-people cash expense were partially offset by an effective net increase in taxes of $358,000 resulting from 2006 recorded tax credits consisting principally of a 2006 Canadian tax GST tax refund of approximately $100,000 and of a $280,000 sales and use tax refund involving a prior year transaction with a third-party service provider.

     The $1,558,000 decrease in non-cash expense primarily relates to share-based compensation costs between periods, including a prior-period credit adjustment of $265,000 (see note 4 to the consolidated financial statements). The remaining decrease in share-based compensation costs is due to a greater portion of vesting stock options having been granted in 2006 and 2007 with a lower value because of the Company’s then-lower stock price.

     The $3,170,000 decrease in selling, general, and administration expense for 2006 versus 2005consists primarily of a $2,518,000 decrease in personnel costs and $652,000 in non-personnel costs. The principal reasons for the decrease in personnel costs are the divestitures of the MI/WI and Dr. Chart product lines in 2005 and the 2006 reduction in workforce. Personnel costs include salaries and wages, severance pay, contract labor, consulting services, benefits and recruitment. The decrease in non-personnel costs was due to $608,000 in various one-time tax expense reductions relating to state sales tax and international indirect tax refunds and a reduction of state sales and use tax accrued, $276,000 in reduced amortization costs of intangible assets associated with the divestitures of the MI/WI and Dr. Chart product lines in 2005, $1,230,000 decrease in various general administrative items such as external legal, accounting, shareholder-related expenses and insurance, $570,000 for reduced occupancy costs, $221,000 for depreciation expense resulting from certain fixed assets becoming fully depreciated, the 2005 divestitures previously mentioned and the effects of previously recorded impairments on certain fixed assets and $345,000 for reduced travel, partially offset by an increase of $2,419,000 in share-based compensation costs related to employee and non-employee stock options, a $113,000 increase in marketing and advertising costs and a $66,000 increase for all other sundry costs.

Customer Deposit Forfeiture

     In 2007, 2006 and 2005, the Company recorded $2,000,000, $1,000,000 and $960,000 reduction of certain operating expenses, respectively. These amounts represent forfeitures by sanofi-aventis of a customer deposit in accordance with a Master Services Agreement, which was entered into with sanofi-aventis for $4,000,000 on the same date as the MyDocOnline acquisition (see Note 12 to the consolidated financial statements), which pertained to the Company’s performance of various future services. The services were to be delivered in minimum amounts of $1,000,000, $1,000,000 and $2,000,000 prior to January 30, 2005, January 30, 2006, and January 30, 2007, respectively. Sanofi-aventis never requested the services and, thus, the $4,000,000 customer deposit was forfeited. The Company believes that the forfeitures of the deposit were most likely associated with a change in strategic direction that came about as a result of the merger between Sanofi and Aventis and the resulting change in personnel.

Gain/Loss on Sale of Product Lines

     In 2006, the Company recorded a gain of $53,000 resulting from the receipt of payments from MITEM, the purchaser of Dr. Chart in 2005, under the fully reserved note receivable issued by MITEM in partial payment for the Dr. Chart assets. The payments were recorded as a gain on the sale of the product line and reduced the overall loss on the sale of Dr. Chart to $4,698,000. Future gains could be recorded if MITEM makes any further payments on the promissory note. See Note 6 to the consolidated financial statements.

     In 2005, the Company recorded a net loss totaling $3,716,000 as a result of two separate product line-related dispositions:

	•		On March 11, 2005, the Company sold its Web Inspector and Message Inspector product lines to CyberGuard Corporation. The total sales price was $3,626,000 consisting of $2,126,000 in cash and a $1,500,000 note receivable due in three equal payments in 2005, which was subsequently paid in full. The net gain recognized on the sale of the Web Inspector and Message Inspector product lines was $1,035,000.
	•		On September 30, 2005, the Company sold its Dr. Chart product line to MITEM. The total sales price was $700,000 consisting of $150,000 in cash and a note receivable in the original principal amount of $550,000, which was subject to adjustments at closing. The note was fully reserved due to the Company’s determination that collection was not reasonably likely given MITEM’s financial position, the early stages of its product development and the extended payment terms of the note. The Company recognized a net loss on the sale of Dr. Chart of $4,751,000.

     The sales of Web Inspector and Message Inspector and Dr. Chart are further discussed in Note 6 to the consolidated financial statements.

Asset Impairment Charge

     In 2006 and 2005, the Company recorded impairment charges of $125,000 and $288,000, respectively, on fixed assets that were not being utilized and which had no perceived future value other than estimated market value. These assets were not disposed of and, theoretically, could be utilized by the Company in the future; however, the Company concluded that the fixed assets should be recorded at the estimated market value.

Loss on Impairment of Operating Lease

     On April 11, 2007, the Company subleased its leased premises located in Mason, Ohio, which it was no longer occupying. The term of the sublease agreement coincides with the Company’s original lease. The Company will continue to record rent expense throughout the sublease period commencing in April 2007 in the amounts of $79,000, $107,000 and $90,000 for years 2007, 2008 and 2009, respectively. These expenses will be partially offset by the receipt of sublease payments totaling $32,000, $79,000, and $65,000 in years 2007, 2008, and 2009, respectively and recorded to other income. Sublease payments received in 2007 totaled, $32,000.

     Interest expense decreased $955,000 in 2007 when compared to 2006. The reduction in interest expense is attributable to the restructuring of the sanofi-aventis note in early 2007 and payment-in-full of the note in December 2007. The decrease in interest expense from 2005 to 2006 of $5,722,000 is attributable to the retirement of the Company’s $20,000,000 convertible promissory notes in the second half of 2005 and first half of 2006 (See Note 13 to the consolidated financial statements).

Investment and Other Income

     Investment and other income was $640,000, $925,000 and $776,000 for the years ended December 31, 2007, 2006 and 2005, respectively. The decrease in 2007 versus 2006 was primarily due to the Company’s lower cash balances in 2007. The increase in 2006 over 2005 is attributable to higher interest rates earned on cash balances.

Gain on Valuation of Derivative Liabilities

     On April 5, 2006, the Company sold 9,930,000 shares of common stock and 5,958,000 warrants to various investors (see Note 14 to the consolidated financial statements). Due to certain terms included in the private placement and as explained in Note 14 to the consolidated financial statements, some elements of the transaction were recorded as derivative liabilities and were revalued each quarter with the change in value being recorded as a gain or loss on the consolidated statements of operations. For the year ended December 31, 2006, the Company recorded gains of $4,043,000 on the quarterly revaluation of the derivative liabilities.

     On December 21, 2006, the FASB issued Staff Position EITF 00-19-2, Accounting for Registration Payment Arrangements which caused the Company to prospectively adjust its accounting for the derivative liabilities relating to the 2006 private placement. Based on EITF 00-19-2, the Company reversed $4,029,000 of the gains originally recorded in the second and third quarters of 2006 through a cumulative adjustment to the September 30, 2006, accumulated deficit (see Note 14 to the consolidated financial statements).

Income Taxes

     The income tax benefit on the loss from continuing operations in 2007, 2006 and 2005 is different from the U.S. statutory rate of 34%, primarily due to unbenefitted U.S. losses. The Company’s $181,000 income tax expense for 2007, the $60,000 income tax benefit for 2006 and the income tax expense of $89,000 for 2005 represent non-U.S. taxes resulting from the operations of the Company’s Canadian subsidiary and state income taxes. The Company has fully reserved its U.S. net deferred tax assets in 2007, 2006 and 2005 due to the uncertainty of future taxable income. The 2006 benefit related to the Canadian subsidiary and resulted primarily from the application for and acceptance of certain scientific research and experimental development claims for years 2004 and 2005 not originally reflected in the respective, annual accrued tax liabilities.

     Currently, the Company’s net operating loss carryforwards do not have limitations due to ownership changes, as defined by Section 382 of the Internal Revenue Code. However, future ownership changes may limit the Company’s ability to fully use the net operating loss carryforwards against any future taxable income.

     As of January 1, 2007, the Company adopted the FASB Interpretation No. 48 (“FIN 48”), “Accounting for Uncertainty in Income Taxes — an Interpretation of FASB Statement No. 109 Accounting for Income Taxes.” The current Company policy classifies any interest paid due to an underpayment of income taxes as interest expense and classifies any statutory penalties paid as selling, general and administrative expense. There was an immaterial amount of interest expense recognized related to income taxes for the twelve months ended December 31, 2007. There was an immaterial amount of selling, general and administrative expense recognized for the same periods. The Company has not taken a tax position that would have a material effect on the financial statements or the effective tax rate for the twelve-months ended December 31, 2007, or during the prior three years under FIN 48. The Company has determined it is not reasonably possible for the amounts of unrecognized tax benefits to significantly increase or decrease within twelve months of the adoption of FIN 48. The Company is currently subject to a three year statute of limitations by major tax jurisdictions.

     Prior to the adoption of FIN 48, the Company had recorded a $400,000 tax contingency liability. This amount has remained unchanged under FIN 48.

Net Loss

     As a result of the foregoing, the Company experienced losses from continuing operations of $8,102,000 in 2007, $19,508,000 in 2006, and $43,596,000 in 2005.

     The following table summarizes the unusual components included in the net loss for these three years.

     Additionally, the Company’s net loss in 2005 included interest expense of $6,848,000. As explained previously, a significant amount of the 2005 net loss included items which are non-recurring after December 31, 2005, such as the amortization of the beneficial conversion feature from the debt restructuring. By comparison, the interest expense in 2007 was $171,000, and in 2006 was $1,126,000.

Liquidity and Capital Resources

Overview

     Due to the Company’s history of operating spending being in excess of customer receipts, liquidity has been and continues to be an item of particular focus for the Company’s management. Essential to liquidity is the ability of the Company to meet its obligations as they become due and in the ordinary course of business. The Company believes it has adequate resources and liquidity to sustain operations for the next twelve months as further detailed below. However, the Company operates in only two markets, both of which are still developing and emerging which makes predicting future cash flows difficult.

     Since 2004, the Company has focused on growing its “core” businesses of Email Encryption and e-Prescribing and reducing its operating expenses structure when compared to prior years. Both of these strategies were aimed at enabling the Company to become cash flow break-even in the near-term. These initiatives have continued into 2007 and the Company concluded calendar year 2007 with no short-term or long-term indebtedness for borrowed monies.

     The Company has total contractual obligations over the next year of $1,220,000 and $3,342,000 over the next three years consisting of various office lease contracts (see Note 18 to the consolidated financial statements). Cash usage in excess of these commitments represents operating spending to satisfy existing customer contracts and cover various corporate overhead costs, as well as investments that the Company chooses to make to secure new orders. The Company believes that a significant portion of the spending in excess of contractual commitments is discretionary and flexible.

     The Company is engaged in two primary markets: Email Encryption and e-Prescribing. Both are subscription businesses that share a common business model. First, the service is established and maintained, which requires a start-up cost and recurring fixed costs. Subscribers are then acquired and brought onto the service, which requires a variable acquisition cost of selling and marketing, installation and deployment. Subscribers are recruited with the goal of reaching a level of subscriber payments that exceeds the fixed recurring service costs. Therefore, both the rate at which new subscribers are added and the ability to retain subscribers is essential to operational cash flow breakeven.

     Operationally, the future cash flow of the Company is primarily dependent upon the following key metrics:

	•		Rate of new subscriptions (termed “new first year orders”) for the Email Encryption Service;
	•		Renewal rates for the Email Encryption Service;
	•		Additional payor sponsorship of the e-Prescribing service to physicians by new or existing insurance payors;
	•		Successful adoption and usage of the e-Prescribing service by physicians;
	•		Retention of the users (physicians) of the e-Prescribing service as indicated by subscription renewals;
	•		Future transaction fees (or related fees) associated with the use of the e-Prescribing service; and
	•		Our ability to increase business volume with reasonable cost increases.

      Email Encryption — The recurring nature of the Email Encryption subscription model makes cash receipts naturally rise in a predictable manner assuming adequate subscription renewal and continued new additions to the subscription base. Adding to the predictability is the Company’s model of selling primarily three-year subscription contracts for Email Encryption with the fees paid annually at the inception of each year of service. In 2007 and 2006, cash receipts from Email Encryption operations exceeded cash expenses attributable to Email Encryption. The Company achieved the cash flow positive state by keeping costs relatively flat while continuing to book new first-year orders (approximately $5,500,000 in 2007 and $4,700,000 in 2006), as well as maintaining a high

customer renewal rate of existing customers whose initial contracted service period had expired. This rate has consistently remained above 95% for years 2007, 2006 and 2005. The Company expects the Email Encryption business to continue generating cash receipts in excess of its specific operating costs in 2008 and beyond assuming continued addition of new subscribers at historical rates and maintaining consistent subscriber renewal rates.

      e-Prescribing — The e-Prescribing service and corresponding market is significantly earlier in its development phase when compared to Email Encryption; thus, the Company has chosen to spend money in excess of the cash receipts to build an e-Prescribing subscription base with the target of reaching a level of subscribers required to overcome the spending needed to profitably provide the service. The Company currently estimates a range of 10,000 to 12,000 active users (subscribers) are needed for these fixed costs to be overcome.

     At the end of 2007, the Company had eight insurance payors under contract. The Company is currently staffed to deploy in excess of 400 units per quarter and has a backlog of approximately 280 sponsored, but not yet deployed units, which is less than the Company’s backlog of 1,750 units at December 31, 2006. In 2007, the Company deployed approximately 1,950 units. However, not all users to whom the e-Prescribing service is deployed become active. Based on current trends, the Company believes that between 60%-70% of the users deployed in 2007 will ultimately become active users. As of December 31, 2007, the Company had approximately 3,300 active prescribers using the service. Additionally, the Company continues to experience some attrition in its deployed and active user base. As a result of these experiences, the Company continues to review and target changes to its contracts, recruiting and training strategy in an effort to increase active rates.

     Most prescriber user contracts renew on an annual basis. Further, the Company’s payor contracts typically specify that individual physicians using the e-Prescribing service assume responsibility for renewing the service after the first year. However, Blue Cross and Blue Shield of Massachusetts has renewed the service for their qualified active users for a fourth year; and six of the Company’s other seven payors have also agreed to pay for some or all of the subscription fee for active users. (The sponsorship associated with the remaining payor, United Healthcare Services, Inc., was signed in the second half of 2007, and their deployed users are not yet due to renew). For those users that do not meet the required activity level for continued sponsorship by their particular payor, the Company attempts to contract directly with the individual user or medical practice.

     The number of active users required to cover both fixed and variable costs for the e-Prescribing business will be strongly influenced by the volume of electronic prescriptions written and the success in negotiating additional and maintaining existing transaction-based fee structures. The total transaction and usage-based fees recognized as revenue during 2007 were $1,875,000 compared to $1,145,000 in 2006. The Company has a contract with a payor that provides for a shared savings arrangement measured by improvement in physician-user prescribing behavior. The Company has also signed four contracts with transaction-based fees or the equivalent with existing and new healthcare payors. While increasing the number of active users should increase the prescriptions written and thus increase the potential for transaction fees under current agreements, substantial revenue increases from transaction fees will require additional transaction-based fees from new and existing customers. The Company is now focused on securing new transaction fees from existing and new payor customers that sponsor e-prescribing programs, as well as other non-sponsoring payors that have insured members visiting doctors that already use the PocketScript service (via a sponsorship arrangement from another competing payor). In most cases, there are multiple payors in each market and those additional non-sponsorship payors are viewed as potential sources for supplemental fees in return for certain services such as formulary display, drug-to-drug interaction checking and reporting.

     Finally, possible sources for further transaction fees include parties who could benefit from a real-time, electronic connectivity with PocketScript users. For example, the Company is piloting a disease management program with one of its payors which alerts physicians through the e-Prescribing service that a patient may be eligible for enrollment. In the future, disease management companies might be a source of additional fees. Additionally, the Company currently has contracts under which it earns fees for sending prescriptions electronically to the pharmacies and for certain transactions involving prescriptions related to pharmacy benefit managers (PBM).

     The Company continues to closely monitor developments in the e-Prescribing market and will adjust spending in that area commensurate with expected future returns. The extent and timing of the Company’s success (or lack thereof) in the e-prescribing market will have significant impact on liquidity. The extent to which the Company views the e-prescribing market as attractive for investment will determine the Company’s willingness to fund additional operational cash losses if required. The Company believes it has the ability to adjust overall cash spending to react to shortfalls in projected cash.

     For calendar year 2007, the net cash used by operating activities improved $15,235,000 over the comparable period in 2006. Overall, the Email Encryption Service yielded positive cash flow from operations while e-Prescribing had negative cash flow from operations. Cash flow from operations is a management measurement computed from total cash receipts minus cost of revenues and direct costs, but excluding total unallocated expense/income. Email Encryption has seen year-on-year improvement in cash flow because of continued growth in new subscriptions and its high rate of customer renewals. The Company anticipates that year-on-year Email Encryption cash flow improvement should continue as long as new subscriptions and the rate of customer renewals are sustained. The emerging nature of the e-Prescribing market makes the expected cash usage for the Company’s e-Prescribing service in the next twelve months less predictable. Improved cash utilization for the e-Prescribing service is dependent upon securing new or the expansion of existing payor sponsorships, experiencing adequate renewal rates of existing users and increasing the sources of cash from transaction and performance-based fees.

     As reported in the consolidated statements of cash flows, net cash flows used by investing activities was $3,155,000 for the year ended December 31, 2007, compared to net cash flows provided by investing activities of $3,914,000 for the comparable period in 2006. Of these respective yearly totals, $1,431,000 and $1,239,000 were used to purchase various computing equipment primarily to satisfy customer contracts. Most prevalent are purchases of computer servers for the Email Encryption business, which are required to deliver the Company’s services. The other significant activity event included in the total net cash flows used by investing activities for the year ended December 31, 2007, was the purchase of marketable securities totaling $1,734,000. This balance relates primarily to a Letter of Credit in the amount of $1,675,000, issued in favor of sanofi-aventis as security for a $1,600,000 promissory note issued in the first quarter of 2007 by the Company and subsequently paid in 2007 (see Note 13 to the consolidated financial statements). Included in the total net cash flows provided by investing activities for the year ended December 31, 2006, was $5,100,000 of restricted cash, which became unrestricted upon the payment of the convertible promissory note payable in June 2006, and $53,000 of proceeds from the prior year sale of the Dr. Chart product line (See Note 6 to the consolidated financial statements).

     Included in the total net cash flows from investing activities for 2005 was $16,000,000 of cash proceeds from sales of marketable securities, $5,239,000 of cash released from restricted cash accounts and $3,262,000 of net cash received from the sale of product lines. These inflows were partially offset by the purchases of property, plant and equipment of $1,734,000.

     Net cash provided by financing activities for the year ended December 31, 2007, was $2,339,000 compared to net cash provided by financing activities of $5,307,000 for 2006. The total for 2007 consists of $4,194,000 in proceeds from the exercise of warrants and stock options, partially offset by debt-related payments of $1,600,000 on the restructured promissory note in favor of sanofi-aventis (see Note 13 to the consolidated financial statements) and $255,000 relative to an eleven-month note payable to Cananwill, Inc., to finance the Company’s 2007 commercial

insurance requirements. Net cash provided by financing activities in 2006 reflects $10,964,000 of net proceeds from the Company’s April 2006 private placement transaction, partially offset by assorted debt payments of $5,200,000 relating to the Company’s convertible debt at that time and $457,000 for payments made on other various note payables.

     Included in the total net cash flows in financing activities for 2005 was net proceeds of $24,231,000 from a private placement of its common stock and combined proceeds of $2,116,000 from the exercise of warrants and stock options, partially offset by the $7,829,000 of cash used to pay down the various debt instruments, primarily the convertible notes, and certain capital leases.

Cash Sources

     The following items are essential to the Company’s future operating cash sources:

	•		contractual backlog
	•		Email Encryption growth and retention
	•		e-Prescribing growth and retention
	•		e-Prescribing transaction and performance-based fees

      Backlog — The Company’s end-user order backlog of $31,792,000 is comprised of contractually bound customer agreements that are expected to be amortized into revenue as services are provided in the future. The majority of these contracts are time-based subscription contracts with billings in advance of annual service periods. Most customers elect to commit to multiple years of service and are invoiced annually. The backlog is comprised of $16,103,000 of deferred revenue that has been billed and paid and $15,689,000 that has either not yet been billed or has been billed, and not collected in cash as of December 31, 2007. The Company estimates that approximately half of the amount not yet billed will be billed in the next twelve months.

      Email Encryption growth and retention — The Company collected cash receipts of $23,100,000 in the twelve months period ending December 31, 2007. The Company estimates cash receipts from Email Encryption in the next twelve months will be approximately $25,600,000. The Company assumes it will collect contractually billed amounts, experience continued high renewal rates and continue to add new first-year orders in the range of the new first-year orders demonstrated in 2007, experience continued growth in its indirect channels to market and experience continued customer prepayments on some multiple-year contracts. The Company believes that the anticipated increase in cash receipts can be achieved with minimal additional costs.

      e-Prescribing growth and retention — The Company’s go-to-market model in e-Prescribing has been to contract with healthcare payors who pay the Company to provide service to physicians for at least one year. The Company continues to believe this model is the most cost effective method of pursuing the market at this time. The Company has demonstrated selling and deployment success with this model with eight major insurance payors. The Company’s current list price for the first year of the service is $2,000, which includes twelve months of service as well as set up fees, and a $600 per year fee for service in subsequent years. The Company currently has a usage-based arrangement with one of its payors that provides for the payment of fees to the Company based on achievement of measured improvements in prescribing behavior. In light of the relatively low margins on installation and service during the initial year of deployment, the Company’s ability to promote high utilization rates for each prescriber, and thus, to increase the likelihood of renewals and the generation of transaction fees, is a key aspect of the Company’s cash flow breakeven plan for its e-Prescribing business.

      e-Prescribing transaction and performance-based fees — The Company’s go-to-market model in e-Prescribing also involves securing additional contracts where customers pay for various transactions that occur through the e-Prescribing service. For example, the Company has signed four contracts with transaction-based fees or the equivalent with existing and new healthcare payors. The Company also has a contract with a payor that provides for a shared savings payment arrangement measured by improvements in prescribing behavior. Further, in most cases, there are multiple healthcare payors in each market and those additional non-sponsorship payors are viewed as potential sources for additional fees in return for certain services such as formulary display, drug-to-drug interaction checking and reporting.

     Possible sources for further transaction fees include parties who could benefit from a real-time, electronic connectivity with PocketScript users. For example, the Company is piloting a disease management program with one of its payors which alerts physicians through the e-Prescribing service that a patient may be eligible for enrollment. In the future, disease management companies might be a source of additional fees. Additionally, the Company currently has contracts under which it earns fees for sending prescriptions electronically to the pharmacies and for certain transactions involving prescriptions related to pharmacy benefit managers (PBM).

     The number of prescriptions written using the PocketScript service and thus transmitted through the ZixData Center has been growing on a year-over-year basis. In 2007, the Company transacted approximately 7,400,000 prescriptions compared to 5,300,000 prescriptions in 2006. The Company is investing greater sales effort and post-deployment attention to maximizing utilization in order to maximize future revenue potential both through renewals and transaction fees.

     Securing further transaction and performance-based revenue streams in excess of those currently under contract will be required so that the previously discussed targeted range of 10,000 to 12,000 active physician will provide returns in excess of fixed costs of providing the e-Prescribing service.

Cash Requirements

     The Company goal over the next twelve months is to achieve net cash flow break-even from operations. However, unforeseen opportunities in the markets we serve, could call for increased investments delaying this cash flow breakeven point.

     The Company’s cash requirements consist principally of the Company’s contractual commitments; funding its relatively flat operating cost structure; capital expenditures; and any new contractual commitments. Capital expenditures involve primarily computer equipment to support new Email Encryption customer orders and, over time, ongoing refurbishment of the data center and customer-located Email Encryption computer equipment. The Company’s cash requirements beyond contractual commitments are primarily aimed at continued investment in the e-Prescribing business for both research and development and working capital requirements.

     The Company has acquisition costs associated with adding subscribers to both the Email Encryption and e-Prescribing services. For Email Encryption, the costs are primarily selling and marketing, while for e-Prescribing the costs are primarily recruitment and deployment related, including hardware device costs. In the first year of the service, the Company generally targets fees from the payor customer that cover the majority of the incremental acquisition costs. After the first year of service, different fee structures come into play and the incremental cost to support customers decreases significantly. Specifically, the fee structure in the second year of the contract and beyond consists of an annual subscription fee and transaction fees (or the equivalent) from various sources. The ePrescribing business model requires that the combination of the annual subscription fee and the transaction fees (or the equivalent) significantly exceed the customer support expense in the second and subsequent years of service to a prescriber. To the extent that these fees exceed the customer support expense in the second and subsequent years of service, ePrescribing related fixed costs will be offset and profitability will be achieved. It should be noted that net cash contributions from transaction-based fees are high relative to the incremental costs to generate these fees. In 2007, the Company deployed the e-Prescribing service to approximately 1,950 prescribers for a quarterly average of approximately 490 deployments. Future quarters with deployments greater than these quantities will equate to greater variable costs, the major of which will be offset in the first year of the service with greater cash receipts from the sponsors. Conversely, lower deployments would result in lower variable costs and lower cash receipts.

     The Company is projecting its operating spending to be approximately $32,660,000 inclusive of capital equipment purchases for the next twelve months from December 31, 2007. This projection is based on the Company’s organization size after taking into account forecasted order and deployment rates and the annualized operating spending level. As noted earlier, if unforeseen market opportunities materialize, the Company may revise its projected spending level as a result of management’s election to invest to capitalize on these opportunities.

Liquidity Summary

     Based on cash-flow projections, supported by low contractual future spending commitments, historically high customer renewals and continued growth in the Email Encryption Service consistent with past rates, cost containment ability in the emerging area of e-Prescribing, general flexibility in discretionary spending, and total cash on hand, the Company believes it has adequate resources and liquidity to sustain operations for the next twelve months. On December 31, 2007, the total for cash, cash equivalents, marketable securities and restricted cash equaled $12,283,000. The Company’s goal is to be cash flow positive for the six month period ending June 30, 2008. For the balance of 2008, the Company’s ability to achieve cash flow break-even from operations depends on whether business opportunities arise which require the Company to invest working capital resources in one or more lines of business. For example, management may elect to increase its research and development spending to fund new functionality and services. Also, a significant increase in newly contracted deployments for the e-Prescribing service, beyond those deployment levels already forecasted, could increase the spending rate in 2008 because of the significant, upfront variable costs associated with establishing the service for new subscribers.

     The Company has in the past expressed a lack of willingness, relative to other alternatives, to raise capital by issuing new shares of common stock given the recent low price of the Company’s common stock. In light of the more recent increased price of the Company’s common stock, the Company may entertain raising capital for the purpose of funding new product or service development requirements and working capital requirements needed to fund any significant increase in newly contracted deployments for the e-Prescribing service, beyond those deployment levels already forecasted.

     There are no assurances that the Company will ultimately achieve or achieve in a timely manner its desired improvements in liquidity. Should business results not occur as projected, the Company may not achieve its cash flow projections. As a result, it would have to alter its business plan or further augment its cash flow position through cost reduction measures, sales of assets, additional financings (as mentioned above) or a combination of these actions to achieve its December 31, 2008, total cash goal. However, there can be no assurance that the Company would be successful in carrying out any of these measures should they become necessary.

Options and Warrants of ZixCorp Common Stock

     The Company has significant warrants and options outstanding that are currently vested. There is no assurance that any of these options and warrants will be exercised; therefore the extent of future cash inflow from additional warrant and option activity is not certain. The following table summarizes the warrants and options that are outstanding as of December 31, 2007. The vested shares are a subset of the outstanding shares. The value of the shares is the number of shares multiplied by the exercise price for each share.

Off-Balance Sheet Arrangements

     None.

Contractual Obligations and Contingent Liabilities and Commitments

     The following table aggregates the Company’s material contractual cash obligations as of December 31, 2007:

		Payments Due by Period
		Total				< 1 Year				2-3 Years				4-5 Years				> 5 Years
Operating leases		$	6,749,000			$	1,220,000			$	2,122,000			$	1,855,000			$	1,552,000

     ZixCorp has not entered into any material, non-cancelable purchase commitments at December 31, 2007.

     The Company has severance agreements with certain employees which would require the Company to pay approximately $1,743,000 if all such employees separated from employment with the Company following a change of control, as defined in the severance agreements.

Recent Accounting Pronouncements

     In September 2006, the FASB issued Statement of Financial Accounting Standard (“SFAS”) No. 157, “Fair Value Measurements” (“SFAS 157”). SFAS 157 defines fair value, establishes a market-based framework or hierarchy for measuring fair value, and expands disclosures about fair value measurements. SFAS 157 is applicable whenever another accounting pronouncement requires or permits assets and liabilities to be measured at fair value. SFAS 157 does not expand or require any new fair value measures; however the application of this statement may change current practice. The requirements of SFAS 157 are first effective for ZixCorp’s fiscal year beginning January 1, 2008. However, in February 2008 the FASB decided that an entity need not apply this standard to nonfinancial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a nonrecurring basis until the subsequent year. Accordingly, the Company’s adoption of this standard on January 1, 2008, is limited to financial assets and liabilities. The Company does not believe the initial adoption of SFAS 157 will have a material effect on its financial condition or results of operations. However, ZixCorp is still in the process of evaluating this standard with respect to its effect on nonfinancial assets and liabilities and therefore has not yet determined the impact that it will have on the Company’s financial statements upon full adoption.

     In February 2007, FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities Including an Amendment of FASB Statement No. 115.” The fair value option permits entities to choose to measure eligible financial instruments at fair value at specified election dates. The entity will report unrealized gains and losses on the items on which it has elected the fair value option in earnings. SFAS 159 is effective beginning in fiscal year 2008. The Company is currently evaluating the effect of adopting SFAS 159, but does not expect it to have a material impact on its consolidated results of operations or financial condition.

             In December 2007, the SEC issued Staff Accounting Bulletin (“SAB”)  110 Share-Based Payment. SAB 110 amends and replaces Question 6 of Section D.2 of Topic 14, “Share-Based Payment,” of the Staff Accounting Bulletin series. Question 6 of Section D.2 of Topic 14 expresses the views of the staff regarding the use of the “simplified” method in developing an estimate of the expected term of “plain vanilla” share options and allows usage of the “simplified” method for share option grants prior to December 31, 2007. SAB 110 allows public companies which do not have historically sufficient experience to provide a reasonable estimate to continue use of the “simplified” method for estimating the expected term of “plain vanilla” share option grants after December 31, 2007. SAB 110 is effective January 1, 2008. The Company currently uses the “simplified” method to estimate the expected term for share option grants as it does not have enough historical experience to provide a reasonable estimate. The Company will continue to use the “simplified” method until it has enough historical experience to provide a reasonable estimate of expected term in accordance with SAB 110. The Company does not expect SAB 110 will have a material impact on its consolidated balance sheets, statements of operations and cash flows.

     In December 2007, the Financial Accounting Standards Board (“FASB”) issued Statement No. 141R, Business Combinations , and Statement No. 160, Non-controlling Interests in Consolidated Financial Statements, an amendment of ARB No. 51 . Statement No. 141R modifies the accounting and disclosure requirements for business combinations and broadens the scope of the previous standard to apply to all transactions in which one entity obtains control over another business. Statement No. 160 establishes new accounting and reporting standards for non-controlling interests in subsidiaries. The Company will be required to apply the provisions of the new standards in the first quarter of 2009. Early adoption is not permitted for these new standards.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders
Zix Corporation

We have audited Zix Corporation and subsidiaries’ (the “Company”) internal control over financial reporting as of December 31, 2007 based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2007, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of the Company as of December 31, 2007 and 2006, and the related consolidated statements of operations, stockholders’ equity (deficit), and cash flows for the years then ended, and our report dated March 14, 2008, expressed an unqualified opinion on those consolidated financial statements.
