Overview

Guidance Software, Inc. is the leading global provider of software solutions used to conduct digital investigations. Our
EnCase® platform provides an investigative infrastructure that allows our customers the capability to digitally
investigate human resources matters, allegations of fraud, suspicious network endpoint activity and defend their organizations data assets with our forensically sound solutions.

EnCase® Enterprise provides organizations the visibility into user-controlled areas of the network to determine if there are any risks to the data present on their network.
EnCase® Enterprise provides in-depth visibility into laptops, desktops, file servers and email servers to
quickly determine the root cause of suspicious network activity. In addition, powerful incident response capabilities allow an organization to determine exactly what, where, how and when an incident took place along with the tools to remediate any
malicious code or processes running on the affected computers to return the network to a trusted state.

EnCase® eDiscovery is our enterprise-wide eDiscovery solution that operates from a central location to
automatically perform search, collection, preservation and processing of electronically stored information (ESI) from unstructured and semi-structured data stores, such as: workstations, laptops, servers, removable storage devices, archiving and
content management solutions, with no business disruption to end-users. EnCase® eDiscovery scales to meet the
needs of all sizes and types of organizations, while providing a time efficient, cost effective, world class in-house eDiscovery solution.

EnCase® Cybersecurity complements and augments existing IT Security
applications, such as DLP, IDS, or SIM tools, by providing organizations that have identified a high-level alert with forensic-level visibility of the offending endpoint data, valuable information from memory, and the ability to search the
enterprise for identical or similar threats. These capabilities allow a complete investigation of the alert, so an organization can understand the extent and location(s) of the problem.

The widespread reliance on digital business processes and the explosive growth in the volume of electronic data have resulted in exposure to
electronic data-related risks and created the need to properly conduct digital investigations.The global adoption of local area networks, wide area networks, e-mail and the Internet have increased communications within and between
organizations and have created the ability to generate, store, share and distribute massive amounts of electronic information instantaneously without regard to physical location. While the adoption and reliance on these technologies has
significantly increased productivity and lowered the cost of doing business for Global 2000 companies, government agencies and other organizations, it has also exposed organizations to many increasing areas of risk associated with the continued
proliferation of electronic data. Organizations now are increasingly faced with the need to recover and analyze vast amounts of electronic data quickly and efficiently through processes we refer to as digital investigations. Digital investigations
are conducted to address various electronic data-related needs, including:



| |  |  | searching, collecting and processing litigation-related data, or responding to discovery requests for electronic data, or eDiscovery
requests, where a company must conduct a thorough yet timely review of electronic data in order to produce forensically sound electronic documents or other digital evidence in connection with a particular civil or administrative proceeding;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | responding to regulatory data requests, where an organization must efficiently and rapidly produce electronic documents and digital evidence in
connection with a project under regulatory review in a manner acceptable to the regulators;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | addressing corporate policy violations, such as intellectual property theft, employee fraud and employee policy violations, all of which must be
investigated rapidly, described in a detailed, complete and comprehensible report of the incident and mitigated and remedied across an enterprise network as necessary, all while minimizing business interruption; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | responding to IT security attacks or breaches, where an organization must expeditiously and unobtrusively determine which systems or files were
affected, the nature of the attack and how to remediate the issue quickly before any further damage occurs.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Traditional digital investigations involve internal investigators or third-party consultants manually searching through multitudes of electronic data in an attempt to discover traces or fingerprints of electronic data-related
incidents. Such investigators or third-party consultants typically use software applications, utilities or processes, such as taking the affected servers, desktops and laptops off-line, so that they can remove, image or copy the hard drives,
manually extract the data in question on each affected computer and save the affected files to another hard drive for processing and analysis by consultants or other third-party experts. These traditional digital investigations suffer from several
distinct problems in that they are costly and time-consuming, they require significant expertise to conduct across complex enterprise network environments, they may not adequately combat attempts to conceal data, they often result in unwanted
exposure of sensitive materials and disrupt business, and they are difficult to conduct in a forensically sound manner. Establishing a comprehensive digital investigative software platform can help organizations address the inadequacies of
traditional digital investigations and cost-effectively mitigate the risk of electronic data-related threats.

We complement our software offerings with a comprehensive array of professional and training services including technical support and maintenance services to help our customers implement our solutions, conduct investigations and train their
IT and legal professionals to effectively and efficiently use our software products. All of our brands are based on the EnCase® platform, and our products are used by a wide variety of industries and some of the worlds best known technology, financial and insurance services, defense,
energy, pharmaceutical, manufacturing, healthcare and retail companies. Our EnCase® Enterprise customer base
currently includes more than half of the Fortune 100 and more than 140 companies in the Fortune 500, and we have sold our EnCase® Forensic software to more than 1,000 government and law enforcement agencies and other customers worldwide.

For the fiscal year ended December 31, 2009, we reported total revenues of $74.9 million, employed approximately 350 employees and
conducted business in over 75 countries. We were incorporated in California in November 1997 and reincorporated in Delaware in December 2006.

Business Strategy

internal investigations, including those related to human resources or those focused on compliance or fraud. Companies can also collect and preserve data in response to requests from regulators or for civil litigation matters and take decisive
action in the face of security and data breaches, whether the origin of the worm, virus or other exploit is internal (e.g., rogue employees) or external (e.g., hackers).

EnCase® Enterprise serves as the platform for an enterprise investigative infrastructure, to which additional products can be added to enhance and automate the search,
collection, preservation and analysis of data in order to accomplish specific business tasks such as: responding to electronic discovery requests; performing proactive, enterprise-wide, data audits for sensitive information, including personally
identifiable information, classified data, and intellectual property; and responding to and remediating network threats or intrusions. These products, which can be added to perform the functions above, include EnCase® eDiscovery, EnCase® Legal Hold and EnCase®
Cybersecurity. The core EnCase® Enterprise platform consists of five separate components: the Examiner, the SAFE
Secure Authentication for EnCase®, the Servlet, the Enterprise Concurrent Connections and SnapShot.

EnCase® eDiscovery

EnCase® eDiscovery performs automated search, collection, preservation and processing of ESI around the
clock in a forensically sound manner. Using a distributed enterprise-wide scalable architecture, it collects and processes only potentially relevant data. In addition, evidence and metadata are preserved in the court validated EnCase® Evidence File format to ensure complete chain of custody from the moment the legal hold is issued until load files
are generated for attorney review. EnCase® eDiscovery tracks collection results in a database so that the status
of the data collection effort can be viewed and communicated to others.

Once the initial search has been
conducted and the information has been collected, EnCase® eDiscovery then is able to cull and process the data
to further reduce the volume of irrelevant or duplicate information. The solution distributes processing in an organized fashion so that several dozen machines can process terabytes of data without disrupting business and degrading network
performance. EnCase® eDiscoverys robust in-house processing capabilities enable secondary culling and load
file creation for the most common attorney review platforms. The collected and processed data is placed in a court-validated digital container called an EnCase® Logical Evidence file, or LEF, and the data can be uploaded to third-party eDiscovery attorney review platforms to complete the eDiscovery process.

Our pricing model for this software is unique. In addition to a traditional perpetual software license, in which the license revenue is
recorded once we deliver the product to our customer (presuming all other criteria of revenue recognition have been met), we enable customers to pay for eDiscovery software as they use it under a Pay-Per-Use pricing option, whereby revenue will be
recorded as our customers use the software to search, collect and process data. In addition to our corporate clients, the Pay-Per-Use pricing option is ideally suited to enable third party service providers with our software offering.

The eDiscovery market has been fragmented, lacking a fully integrated
solution, and relying on multiple point solutions, which breeds inefficiencies, causes delays, increase risk and, ultimately, costs. Typically, in any given technology market, the introduction of integrated offerings drives broader technology
adoption, and the eDiscovery market should be no different. In January 2010, the Company announced the anticipated release in the second quarter of 2010 of Version 4 of EnCase® eDiscovery, the industrys first fully integrated eDiscovery solution. Version 4 of EnCase® eDiscovery will provide customers legal and IT teams with one integrated software solution that delivers all of the functionality that organizations desire for
in-house electronic discovery, including:

EnCase®Legal Hold

EnCase® Legal Hold is a web-based add-on to the EnCase® eDiscovery platform that enables corporate legal departments not only to identify and notify custodians for legal preservation holds at the outset of litigation, but
also to manage, track and report on the actual preservation, collection, and processing of electronically stored information (ESI).

Applicable law requires litigants to preserve potentially relevant information when litigation can reasonably be anticipated. Many current litigation hold solutions, however, do not provide an integrated technical means to systematically
collect and process data from custodians subject to litigation holds. Instead of an integrated solution, they merely send and track emails to custodians, often while promoting custodian self-collection, which has drawn harsh scrutiny from the courts
and presents risks such as non-compliance, under- or over-collection, metadata alteration or spoliation, inadequate chain of custody documentation, authentication challenges and business disruption.

EnCase® Legal Holds tight integration with EnCase® eDiscovery makes it possible not only to notify and interview custodians, but also to track and report on the collection and processing of ESI performed with
EnCase® eDiscovery. Users can issue litigation holds, interview custodians, monitor compliance with the holds
and track the progress of collection and processing of potentially relevant ESI. We began shipment of EnCase®
Legal Hold in 2009.

EnCase® Cybersecurity

EnCase® Cybersecurity augments and complements existing IT security investments by enabling proactive
audit capabilities across all network endpoints, including file and email servers enabling security teams to focus in on problem areas quickly. The solution audits for suspicious or sensitive data, such as account or credit card numbers, or
unauthorized files or applications that violate policies or regulatory mandates and remove it with thorough remediation capabilities.

It ensures network endpoints remain in a trusted state by identifying threats that evade perimeter defenses, including different iterations of polymorphic malware. EnCase® Cybersecurity enables fast response to high- priority alerts by scanning the network for similar problems, and by
empowering endpoint recovery from malware and remediate data from unauthorized locations without disruption to operations. EnCase® Cybersecurity works with existing IT security applications, such as DLP, IDS, or SIM tools by providing forensic-level visibility of the offending endpoint data,
valuable information from memory, and the ability to

search the enterprise for identical or similar threats. With these key capabilitiesdetermining the extent of threats, proactively auditing to identify potential problems before they cause
harm, and allowing for remediation of targeted dataEnCase® Cybersecurity rounds out an organizations
security profile and helps safeguard its business. We began shipments of EnCase® Cybersecurity in 2009.

EnCase® Forensic

EnCase® Forensic software is the industry leading tool for searching, collecting, preserving and
analyzing computer forensic data and authenticating such data in court. EnCase® Forensic enables an investigator
to conduct the full array of forensic functions on a single machine while preserving the integrity of the evidence for future use in court. Used by investigators and consultants in law enforcement, government agencies, small businesses, consulting
firms and corporations, EnCase® Forensic software provides a robust way to authenticate, search and recover
computer evidence rapidly and thoroughly.

EnCase® Forensic has the same capabilities as the Examiner in our EnCase® Enterprise software, other than the capability to search across networks. Computer evidence recovered with EnCase® Forensic software has been approved and validated in thousands of court proceedings in local, state and federal jurisdictions all over the world.

EnCase®Portable

In 2009, we released EnCase® Portable, an automated search and collection solution that anyone can use.
It enables personnel not trained in computer forensics to forensically acquire documents, Internet history and artifacts, images, and other digital evidence, including entire hard drives all by connecting a USB device rather than a laptop. Also, law
enforcement, government, law firm and corporate customers can cost effectively target systems that are not on the network, cannot be transported or multiple systems simultaneously where it is cost prohibitive to acquire data with laptops.
EnCase® Portable leverages the powerful search and acquisition capabilities of EnCase® software.

Professional Services

Our Professional Services Division provides
various consulting services to our clients, including eDiscovery, network security incident response, civil/criminal digital investigation and implementation services. In addition, we offer certain packaged services based on the specific needs of
our customers, including our government customers. We have security clearances that enable us to better service our Department of Defense customers.

eDiscovery Services. We offer complete end-to-end eDiscovery consulting and project management services, from litigation hold to the production of files for attorney review. Leveraging our industry
leading EnCase® eDiscovery solution, our cost effective eDiscovery services teams automate operations that other
service providers perform manually, and are able to conduct large scale eDiscovery search, collection and preservation from a central location, producing fast, accurate results with minimal business disruption.

Incident Response Services.Using EnCase® Cybersecurity, consultants investigate and remediate security breaches in an organizations network infrastructure. Consultants determine which methods of entry
were used to break into the system, the extent and duration of the intrusion and exactly what data was compromised. They can also kill malware and/or rogue processes. In the event that a breach draws the attention of regulatory agencies,
the Incident Response Services results and reports can be processed into a court-approved, forensically sound file format to help an organization provide accurate, defensible evidence and information to regulators.

Implementation Services.We provide implementation and consulting services in connection with the deployment of
our EnCase® Enterprise, EnCase® eDiscovery, EnCase®
Cybersecurity and related software. Our

on-site training to ensure our customers can maximize the use of the EnCase® Enterprise technology. Our
consultants are encouraged to recommend our add-on products to our customers in order to further enhance the capabilities of our EnCase® Enterprise software.

Guidance Software
Advisory Program (GAP).GAP provides a comprehensive review of current policies and procedures, including a gap analysis which identifies risk areas that could impact the customer. Dedicated advisory consultants work with the customer to build
and implement a customized plan to help automate procedures and eliminate wasted resources, establish a documented, defensible and repeatable eDiscovery workflow, and align procedures with industry best practices.

Customer Service and Technical Support

Customers typically purchase software maintenance with each new product license. Customer support generally involves software updates, telephone and e-mail support, on a 24 hours per day, five days per
week basis, as well as customer self-service on our website. Customers are typically provided an option to renew their maintenance agreements on an annual basis. Our technical support organization provides product support to our current customers
with multi-tiered offerings and includes support availability 24 hours per day, five days per week, in English, and is also available during normal business hours in several other languages, including German and Spanish.

Training

Our Training Division trains thousands of students per year in computer forensics principles and the use of our EnCase® software products and methodology. Because of the sensitive nature of digital investigations and the need to conduct digital investigations in a forensically sound
manner, our users will typically take one or more of our courses. We provide an array of training courses on topics such as computer forensics, digital investigations, the proper use of our software products and the EnScript® programming language, which teach our customers IT and data security professionals the basic principles of
computer forensics, train them on the basic and advanced capabilities of our software products and teach them to write EnScript® programs. We have retained third-party training partners in order to provide training around the world. Our extensive training program has enabled us to create a
human capital knowledge base that can expand the recognition and demand for our products and services.

We operate two
training classrooms in Pasadena, California, two near Washington, D.C., one in Houston, Texas, one near Chicago, Illinois and two near London, England. In addition, through our training staff, our authorized training partners and OnDemand training
program, certain courses are offered at off-site locations throughout North, Central and South America, Europe, Africa, the Middle East and the Asia/Pacific Rim. In 2009, we conducted training classes in 46 different countries. In addition to
offering courses in English, we have begun to localize our courses by converting the course content and manuals into other languages, and delivering the courses in those languages. To date, we have created courses in German, Spanish, Korean,
Romanian, Polish, Japanese and Chinese. During 2008, we also began offering online-training courses, which we call OnDemand training.

Many of our courses are eligible for credit from a variety of organizations, including The State Bar of California, the International Information Systems Security Consortium, Inc., the National Association of State Boards of Accountancy,
the Association of Certified Fraud Examiners, the High Tech Crime Network, the Texas Commission on Law Enforcement and the California Commission on Peace Officer Standards and Training. We are continually expanding our training offerings and we
believe that we are the leading corporate provider of this type of digital investigation training.

EnCE® Certification

The EnCE® program certifies the competency of public and private sector employees in the best practices
of computer forensic investigations and in the proper use of EnCase® while conducting such investigations. In
order to obtain EnCE® certification, professionals must have at least 12 months of computer forensic experience
or attended 64 hours of authorized computer forensic training and pass a dual-phase EnCE® examination. EnCE® certification acknowledges that professionals have mastered computer forensic investigation methodology as well as
the use of EnCase® during complex computer examinations. Our EnCE® program is recognized by both the law enforcement and corporate communities as a symbol of in-depth computer forensics knowledge, and EnCE® certification illustrates that an investigator is a skilled computer examiner. As of December 31, 2009, more
than 2,400 people worldwide had achieved EnCE® certification.

EnCEP Certification

In late 2009 the EnCase® Certified eDiscovery Practitioner (EnCEP) certification was developed. The program certifies private and public sector professionals in the use of Guidance
Softwares EnCase® eDiscovery software, as well as their proficiency in eDiscovery planning, project
management and best practices spanning legal hold to load file creation. EnCase® eDiscovery is the leading
eDiscovery solution for the search, collection, preservation, and processing of electronically stored information (ESI). Earning the EnCEP certification illustrates that a practitioner is skilled in the application of the solution to manage and
successfully complete all sizes of eDiscovery matters in accordance with the Federal Rules of Civil Procedure.

In order to obtain the EnCEP Certification the professionals need to have attended the live
EnCase® eDiscovery training course or completed the EnCase® On-Demand eDiscovery training course or completed the on-site EnCase® eDiscovery implementation training (2009 or earlier, with certificate of training); and have three months experience in eDiscovery collection, processing and/or
project management; in addition to passing both written and practical examinations. As of December 31, 2009, 13 professionals were EnCEP Certified.

Technology

Both our EnCase® Enterprise and EnCase®
Forensic software share three primary components of our technology.

EnCase® Evidence File

Our EnCase® Evidence File and EnCase®
Logical Evidence Files are proprietary solutions that streamline the collection and preservation of digital evidence in investigations. The Evidence File authenticates the digital evidence by verifying that the digital fingerprint and checksums of
small blocks of the collected data matches up with the original data. Our technology can verify the data on-the-fly, such that when a user attempts to view any portion of the evidence, it is instantly verified for authenticity first. By collecting
the digital evidence from the investigator at the time of collection and writing that data into our EnCase®
Evidence Files and EnCase® Logical Evidence Files, we are able to track the chain-of-custody and significantly
reduce the burden on the investigator to authenticate the evidence in court. Our customers can use our EnCase®
Logical Evidence File to store individual files or fragments of data and preserve them in the Logical Evidence File. The EnCase® Logical Evidence File is a significant component of our eDiscovery products and services.

The key benefits provided by the EnCase® Evidence File and EnCase®
Logical Files are that they:



| |  |  | authenticate that the preserved digital evidence is in fact what was originally collected;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | prevent damage to the digital evidence by human error;
| | - |  | ------------------------------------------------------



| |  |  | document the chain-of-custody;
| | - |  | ------------------------------



| |  |  | eliminate cross-contamination concerns;

| |  |  | significantly reduce the need for storage resources.
| | - |  | ----------------------------------------------------

Specialized Hard Drive Access

While most software applications
interact and work within the operating system, we have designed our software, specifically our Servlet to run beneath the operating system in order to prevent interference from the operating system and ensure that data is not
tampered with or modified. By working beneath the operating system, our technology accesses the hard drive at the sector level, which is the smallest writeable area on a hard drive. The Servlet reads data from the sectors on the hard drive in a raw
format and makes the entire hard drive accessible to the user of our software, including all files and obscure areas. Importantly, areas of the hard drive that common users cannot access, such as unallocated space and unformatted space, are also
made accessible through our technology. While scanning the hard drive, our technology does not modify the metadata, such as filenames, dates, and times, on live systems, which enables our customers to conduct a complete examination of all the data
on the hard drive while assuring that the impact on the overall computing environment is substantially non-invasive. This process is critical in order to preserve the forensic integrity of the preserved data and metadata.

EnScript® Technology

We
have designed a proprietary advanced programming language called EnScript® that permits the development of
applications that run inside the EnCase® environment. EnCase® acts as the operating system for these applications. The EnScript® language is optimized for our software and enables our users to quickly write powerful applications that are highly customized to their needs. The EnScript® language permits not only us to develop these applications, but also any other highly skilled programmer,
organization or customer who so desires. The EnScript® program can be compiled so the source code is not
available to others, thereby allowing developers and organizations to protect their intellectual property. In addition to our own development efforts, EnScript® programs are commonly developed by persons not affiliated with our organization, and are distributed throughout the different investigative communities and
organizations.

EnCase® Enterprises Network Level Capability

Our EnCase® Enterprise software extends the capabilities of our
EnCase® Forensic software to enable our customers to scan hundreds or thousands of servers, desktops and laptops
over a network to provide scalable enterprise-class performance. Using EnCase® Enterprise, our customers can
focus on the computers in question in a massive enterprise-scale investigation or emergency, analyze data or files on a network, including volatile memory, and preserve only the data necessary for the investigation into our EnCase® Logical Evidence File. To accomplish this network-level capability securely, we designed and patented a security
architecture that is based on a three-tier structure, which includes a Servlet, an Examiner and a SAFE server.

Designed to work across multiple operating systems, our EnCase® Enterprise serves as an investigative
platform, the foundation of an enterprise investigative infrastructure, when fully implemented on a network. Our software is currently compatible with many systems, such as:



| |  |  | Operating Systems: Windows 95/98/NT/2000/XP/Vista/7, Windows 2003 Server, Macintosh, Linux Kernel 2.4 and above, Solaris 8/9 (both 32-bit and 64-bit),
AIX, and OS X.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | File Systems: FAT12, FAT16, FAT32, New Technology File System (NTFS), Macintosh HFS, HFS+, Sun Solaris UFS, Linux EXT2/3, Reiser, BSD FFS,
Palm, TiVo Series One and Two, AIX JFS, JFS, Joliet, UDF and ISO 9660.

Sales and Distribution

We sell our product offerings directly to customers using our direct geographic and account-based sales representatives, our inside-sales staff, and indirectly through strategic partners, third-party
value-added resellers, or VARs, and distributors. As of December 31, 2009, we employed 119 individuals who were involved in our selling and marketing efforts, and had agreements with over 100 third-party distributors.

The sales model for our EnCase® Enterprise products and services is highly focused on addressing the pervasive and high-value corporate and government agency business problems of electronic
discovery and digital investigations related to litigation, general investigations, information security, risk and compliance. Our direct geographic and account-based sales representatives, otherwise referred to as Account Executives, or AEs, are
divided into Commercial and Public Sector teams and are focused on selling our EnCase® Enterprise products and
related services to corporations and both federal and state and local government agencies. These direct AEs are focused on the North American and UK commercial markets, and US and EMEA government agencies. In focusing our direct sales force on the
core markets of US commercial, US government and the UK commercial and government market, we are able to leverage our large reference ability and market-leadership to rapidly add net-new Enterprise customers and establish a solid foothold in a large
segment of the Fortune 500, Financial Times and London Stock Exchange 250 (FTSE 250) and Global 2000. Additionally, this direct sales focus in these core markets allows us to fully leverage our large and growing EnCase® Enterprise installed base and up-sell those accounts to our high-value EnCase® eDiscovery and EnCase® Cybersecurity solutions. This direct sales focus also allows us to market add-on modules and components to our customers, which in turn allows them to further expand
and scale their investigative infrastructure.

A significant change in 2009 was the expansion of our worldwide channel
program, with a focus on establishing an overlay channel in our US and UK markets, which rely primarily on direct sales efforts. To augment our direct sales efforts in the core US and UK markets, we established several strategic partnerships with
consulting firms and service providers, as well as VAR relationships with major IT reseller/consulting firms. By overlaying a growing indirect channel model over our direct sales efforts, we have been able to increase our access to our target
Fortune 500, FTSE 250 clients while also expanding our reach across a much broader segment of the market to include the small and medium business market segment.

International sales constituted approximately 21% of our sales in the year ended December 31, 2009. Globally, we
continue to expand our worldwide channel partner program by placing an increased emphasis on recruiting and enabling enterprise software VARs and distributors. Historically, our channel focus was centered on the EnCase® Forensic product line, which targeted global law enforcement and government agencies. In 2009, we began introducing
new enterprise-class VARs into our global channel initiative to further expand our expertise and sales capacity for our EnCase® Enterprise family of solutions.

Our inside sales representatives, or ISRs, are responsible for sales of our EnCase® Forensic products
and training services, as well as augmenting our direct sales force with our flagship EnCase® Enterprise
solution. Historically, a large portion of the business for our EnCase® Forensic product has been generated from
pre-existing relationships, allowing our internal sales personnel to execute at a high level of efficiency. Our ISRs continue to spend a large portion of their time targeting our EnCase® Forensic product to law enforcement agencies and consultancies.

In addition to our corporate sales field representatives and our internal sales force, we have a global sales team dedicated to government customers. This US- and UK-based team typically uses a direct
sales model to focus on the specific agencies given the unique selling dynamics, contracting, security clearance, and cross-referencing requirements existing in the global government vertical market.

Marketing

We believe that organizations can realize significant benefits by installing our EnCase® Enterprise
family of applications across their networks in order to address high-value and pervasive business problems such as



9

##### Table of Contents

eDiscovery, data-centric security to include the protection of intellectual property, personally identifiable information, credit card information, and large-scale network security risk
mitigation. These applications all leverage the enabling EnCase® Enterprise platform which offers a base set of
capabilities for conducting enterprise-wide digital investigations and serves as a foundation for organizations to build an investigative infrastructure. Our marketing strategy involves communicating the value of our products for these high-priority
issues to targeted audiences, developing a scenario where the adoption of the EnCase® Enterprise applications
includes the base platform with every opportunity, and then communicating the value of leveraging the EnCase®
Enterprise platform and additional add-on products to the remainder of the organization for future opportunities.

Our marketing programs are focused on regional and vertical market lead-generation campaigns that consist of integrated activities including eMarketing, webinars, direct mail, public relations/media placements, search engine pay-per-click,
online and print advertising and selected events and seminars. Each campaign is focused on matching the appropriate EnCase® Enterprise application with the appropriate target audience, in order to provide the relevant business value messaging to those individuals that are seeking specific
solutions to their most critical business issues. For example, our US Federal lead marketing strategy is centered primarily on EnCase® Cybersecurity, which addresses a vast majority of government network and cyber-security issues. In the US commercial market, however, our lead marketing strategy is
focused around the pervasive and extremely urgent issue of electronic discovery and litigation preparedness. Each campaign leverages best-practice components that are designed to engage our targets, generate leads and progress the
opportunity from initial interest and qualification to opportunity scoping and closing by the Sales organization. We also offer highly educational and informative content (e.g. Webinars, eDiscovery publications, white papers and various collateral)
that facilitates interest in our solutions. This educational approach to our marketing strategy helps to position us as thought leaders and trusted advisors across each of our target markets and drives viral distribution of our information.

In addition to our regional and vertical marketing initiatives, we also host the industrys largest
conference dedicated solely to the subject of digital investigations. The Computer and Enterprise Investigations Conference (CEIC®) serves as our annual user conference and draws attendees from global law enforcement, government agencies, corporations, law firms and judges. This event also draws industry analysts and experts and
provides a valuable forum for users to connect, share information and learn about important topics in the industry. It serves as our singular marketing event and enables us to efficiently connect with a broad range of customers, communicate our
whole product offerings (products, services, training, etc.) and launch new products in a captive environment while simultaneously driving additional add-on sales to customers who have implemented one or more of the core platform products.

Customers

Our customers include government agencies and global corporations in a wide variety of industries such as financial and insurance services, technology, defense contracting, telecom, pharmaceutical,
healthcare, manufacturing and retail. Our EnCase® Enterprise customer base currently includes more than half of
the Fortune 100 and more than 140 of the Fortune 500 and many federal and international government agencies, and we have deployed our EnCase® Forensic software to more than 1,000 government and law enforcement agencies and other customers worldwide. Our EnCase® Enterprise customers are primarily in North America, and also extend to Europe, Africa, the Middle East and Asia/Pacific Rim. Sales to customers outside
of the United States accounted for 21% of our revenues for the fiscal years ended December 31, 2009 and 2008 and 23% for the fiscal year ended December 31, 2007. The majority of our EnCase® Forensic customers are national and local government agencies, law enforcement agencies, consultants and other organizations of the United States and
foreign governments.

Research and Development

Our research and development effort is focused on the advancement of our core products and the development of new products, as well as the quality assurance of both core and new products. We conduct



10



---

##### Table of Contents

research on existing or new computer hardware or software technology to develop solutions for our law enforcement, government or corporate markets. We conduct research on file system support,
search and analysis algorithms, hardware engineering and design, industry standards, technology integrations and user productivity and performance features. Our research and development efforts are often aimed at creating new standards in our
industry and streamlining current processes. Under our customer contracts, we typically obtain the rights to use any improvements to our technology developed or discovered on a particular customer deployment on other customer deployments. Our
research and development expenses were $14.2 million in 2009, $13.0 million in 2008, and $9.0 million in 2007.

Competition

The market for our products is highly competitive, quickly evolving, and subject to rapidly changing technology. The
market for software for electronic discovery is highly fragmented, and our EnCase® eDiscovery product competes
against enterprise search and content management vendors such as Autonomy and EMC, as well as electronic discovery point solutions from smaller, privately held companies. More generally, our EnCase® eDiscovery software competes against providers of outsourced electronic discovery services, such as FTI or Navigant. In the IT Security market, we
believe our EnCase® Cybersecurity product provides certain unique capabilities, but we nevertheless compete for
budget dollars against established IT Security vendors such as Checkpoint and McAfee. In the computer forensics market we compete against a series of smaller, privately held companies, such as AccessData and Paraben. Our competition consists of
forensic vendors including Access Data and security software solution vendors including McAfee and Symantec. With respect to our eDiscovery solution, the market is highly fragmented and we compete against eDiscovery point solutions such as StoredIQ
and Clearwell, information and content management vendors including Autonomy, EMC (which acquired Kazeon), Iron Mountain (which acquired Stratify), as well as other privately held companies. Our eDiscovery solutions also compete against outsourced
eDiscovery alternatives whether eDiscovery service providers or consulting companies, such as the Big 4 consulting/accounting firms and others, that offer services for traditional digital investigations and eDiscovery in place of implementing a
packaged software solution.

We currently compete on the basis of the breadth and depth of our products functionality as
well as on the basis of price. Additionally, we compete on the basis of certain other factors, including forensic technology, forensic soundness and acceptance in court, time required to complete an investigation, ability to scale across large
networks and expertise of consulting personnel. We believe that we currently compete favorably with respect to these factors. For a further discussion of our competition, see Risk FactorsWe face direct and indirect competition from other
software companies, as well as other companies that provide training, consulting, and certification services in computer forensics, which could limit our growth and market share in Item 1A.

Seasonality

Our business
is influenced by seasonal factors, largely due to customer buying patterns. In recent years, we have generally had weaker demand for our software products and services in the first and second quarters of the year and seasonally stronger demand in
the third quarter due to the federal government fiscal year end and in the fourth quarter due to commercial or corporate fiscal year end. Our consulting and education services have sometimes been negatively impacted in the third and fourth quarters
of the year due to the summer and holiday seasons, which result in fewer billable hours for our consultants and fewer education classes.

Intellectual Property and Proprietary Rights

Our intellectual property rights are important to our business.
We rely on a combination of copyrights, trade secrets, trademarks, and patents, as well as confidentiality procedures and contractual provisions to protect our proprietary technology, processes and intellectual property. We currently have three
issued US patents and 17 patent applications pending in the United States, the European Union or under the Patent Cooperation Treaty (often more than one pending application relates to a single invention). We own registered copyrights on various



11

##### Table of Contents

versions of our products and associated instructional documentation. We have registered trademarks or trademarks in the United States and in certain other jurisdictions, including the mark
EnCase® in the United States, Japan and the European Union, and in the marks EnCE®, EnScript®, FastBloc®, Neutrino®, CEIC®, and Guidance Software® in
the United States.

Others may develop products that are similar to our technology. We generally enter into confidentiality
and other written agreements with our employees and partners, and through these and other written agreements, we attempt to control access to and distribution of our software, documentation and other proprietary technology and other information.
Despite our efforts to protect our proprietary rights, third parties may, in an unauthorized manner, attempt to use, copy or otherwise obtain and market or distribute our intellectual property rights or technology or otherwise develop a product with
the same functionality as our software. Policing unauthorized use of our software and intellectual property rights is difficult, and nearly impossible on a worldwide basis. Therefore, we cannot be certain that the steps we have taken or will take in
the future will prevent misappropriation of our technology or intellectual property rights, particularly in foreign countries where we do business or where our software is sold or used, where the laws may not protect proprietary rights as fully as
do the laws of the United States or where the enforcement of such laws is not common or effective.

Substantial litigation
regarding intellectual property rights exists in the software industry. From time to time, in the ordinary course of business, we may be subject to, or initiate, claims relating to our intellectual property rights or those of others, and we expect
that third parties may commence legal proceedings or otherwise assert intellectual property claims against us in the future, particularly as we expand the complexity and scope of our business, the number of similar products increases and the
functionality of these products further overlap. These claims and any resulting litigation could subject us to significant liability for damages. In addition, even if we prevail, litigation could be time-consuming and expensive to defend and could
affect our business materially and adversely. Any claims or litigation from third parties may also limit our ability to use various business processes, software and hardware, other systems, technologies or intellectual property subject to these
claims or litigation, unless we enter into license agreements with the third parties. However, these agreements may be unavailable on commercially reasonable terms, or not available at all.

In addition to our proprietary technology, we rely on technology that we license from third parties. In particular, the next version of our
products will incorporate document viewer technology that we license from Oracle Corporation (formerly, Stellent, Inc.). In November 2008, we agreed with Oracle to extend this license until November 27, 2012 at a higher price. In addition,
Oracle may terminate this license agreement prior to the expiration of its term if we fail to make timely payments or fail to comply with any other material term of the license. (See Risk Factors: Our success depends in part upon our ability
to develop new products and enhance our existing products. Failure to successfully introduce new or enhanced products to the market may adversely affect our business, financial condition and results of operations.)

Employees

As of
December 31, 2009, we employed approximately 350 full-time employees, including approximately 84 in research and development, 119 in selling and marketing and 42 in our Professional Services Division. We have never had any work stoppage and
none of our employees are represented by a labor organization or are party to any collective bargaining arrangements. We consider our employee relations to be good.

Global market and economic conditions may adversely affect our business, results of
operation and financial condition.

We are subject to the risks arising from adverse changes in global economic
conditions, especially those in the US, Europe and the Asia-Pacific region. Economic activity in the United States declined for much of 2009 and macroeconomic conditions also have deteriorated worldwide in 2009. If this economic weakness continues
or worsens, customers may delay, reduce or forego technology purchases, both directly and through our channel partners and resellers. This could result in reductions in sales of our products, longer sales cycles, slower adoption of new technologies
and increased price competition. Further, deteriorating economic conditions could adversely affect our customers and their ability to pay amounts owed to us. Any of these events would likely harm our business, results of operations and financial
condition.

Our operating results may fluctuate from period to period and within each period, which makes our operating
results difficult to predict and could cause our revenues, expenses and profitability to fall short of expectations during certain periods.

Our operating results may fluctuate from period to period or within certain periods as a result of a number of factors, many of which are outside of our control. You should not rely on our past results as
an indication of future performance, as our operating results in the future may fall below expectations, expenses could increase and revenues could decrease. Each of the risks described in this section, as well as other factors, may affect our
operating results. For example, our quarterly revenues and operating results may fluctuate as a result of a variety of factors, including, but not limited to, our lengthy sales cycle, the proportion of revenues attributable to license fees versus
services and maintenance revenue, changes in the level of fixed operating expenses, demand for our products and services, the introduction of new products and product enhancements or upgrades by us or our competitors, changes in customer budgets and
capital expenditure plans, competitive conditions in the industry and general economic conditions. In addition, many customers make major software acquisitions near the end of their fiscal years, which tends to cause our revenues to be higher in the
third and fourth calendar quarters which coincide with the fiscal year ends of many government agencies and corporations, and lower in the first calendar quarter. In addition, many customers tend to make software acquisitions or purchases near the
end of a particular quarter, which tends to make our revenues for a particular period unpredictable for a significant portion of the period in question until software purchase decisions have been made. Since our EnCase® Enterprise product sales are generally large scale license agreements, a short delay in just one of these software
sales from one quarter into a subsequent quarter or a loss of one of these potential sales could cause us to deliver results for a quarter that are below projections of securities analysts that follow our results. There can be no assurance that we
will be able to successfully address these risks, and we may not be profitable in any future period.

If the corporate
market for digital investigation software were not to develop, we would not be able to maintain our growth, and our revenues and results of operations would be adversely affected.

The market for digital investigation software is new and is being developed largely through our efforts. Our growth is dependent upon, among
other things, the size and pace at which the market for such software develops. In 2009, we found that our ability to achieve our anticipated growth rate was impacted by a slow down in the global economy. If the market for such digital investigation
software decreases, remains constant or grows more slowly than we anticipate, we will not be able to maintain the growth rates we experienced prior to 2009. Continued growth in the demand for our products is uncertain because of, among other things:



| |  |  | customers and potential customers may decide to use traditional methods of conducting enterprise investigations, such as reliance on in-house
professionals or outside consultants to conduct manual investigations;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | customers may experience technical difficulty in utilizing digital investigation software or otherwise not achieve their expected return on their
investment in such software; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | marketing efforts and publicity related to digital investigation software may not be successful.

Even if digital investigation software gains wide market acceptance, our software may not
adequately address market requirements and may not continue to gain market acceptance. If digital investigation software generally, or our software specifically, do not gain wide market acceptance, we may not be able to maintain our recent rate of
growth and our revenues and results of operations would be adversely affected.

Additional pricing
models for our EnCase® Enterprise eDiscovery product could negatively impact our revenue.

In the third quarter of 2008, we announced our intention to release a version of our EnCase® Enterprise eDiscovery software that will be billed to customers based upon the volume of data searched, collected,
and processed using the software. We refer to this as our Pay-Per-Use model, and we released this software in the fourth quarter of 2008. Traditionally, our pricing model for this software has been based upon a perpetual license, in which the
license revenue is recorded once we deliver the product to our customer (presuming all other criteria of revenue recognition have been met). Under this new model, revenue will be recorded as our customers use the software to search, collect and
process data, not at the point in which the software is delivered. Through December 31, 2009, we signed Pay-Per-Use agreements with approximately 55 new customers, some of which generated revenue in 2009. In the event that customers in our
current pipeline choose our Pay-Per-Use pricing model instead of a perpetual license model, we could see a decrease in upfront license revenue from our eDiscovery product.

The failure of the legal community to adopt our eDiscovery solution could negatively affect future sales of
EnCase® Enterprise, which could have a material adverse effect on our results of operations.

We expect to derive a significant amount of sales of EnCase® Enterprise from continuing demand for our EnCase® eDiscovery solution. However, widespread adoption of eDiscovery best practices will require a shift in the way the legal community approaches discovery of electronic
documents and other electronically stored data. Currently, most large scale electronic discovery projects are conducted by outsourced service providers that manually retrieve documents from each computer subject to review. These service providers
have longstanding and entrenched relationships with the corporations that are subject to large-scale discovery inquiries or security breaches and the large law firms that are typically retained in connection with such discovery projects.
Corporations and law firms may continue to prefer to use service providers because of these ongoing established relationships, and because the service providers are widely known and accepted within the legal community, and may resist adoption of our
EnCase® eDiscovery solution. Moreover, the expense of relying on an outsourced service provider may frequently
be covered by the corporations insurance policy that is otherwise covering the expense of the litigation, including complying with requests for discovery, while implementation of EnCase® Enterprise and our EnCase®
eDiscovery would require a significant unreimbursed capital expenditure by the corporation. The failure of corporations and law firms to adopt our EnCase® eDiscovery solution for eDiscovery could have a material adverse effect on our sales and results of operations.

Courts could reject the use of our products, which would harm our reputation and negatively affect future sales of our products and
services.

Our software products and services are often used in connection with legal investigations, civil litigation
and criminal prosecutions. The admissibility of results generated by our products as evidence in civil and criminal trials is a key component of our customer value proposition. Evidence and the manner used to collect evidence is regularly the
subject of challenges in legal investigations and litigation, and our products or personnel may be the direct or indirect subject of such legal challenges. Persons involved in litigation may, for example, challenge the reliability of our products,
the admissibility of evidence generated, discovered or collected using our products, and/or the expertise, credibility or reliability of our personnel. Other unpredictable legal challenges may be brought that could reflect upon the reputation of our
products or personnel. To date, courts that have addressed challenges to our products or services have ruled against such challenges. If in the future a court were to find that our products are not reliable or that persons representing us or users
of our product are not credible, reliable or

lack the expertise necessary to serve as a witness or to authenticate evidence, or that our training and certification process does not adequately prepare individuals to conduct competent digital
investigations, this could have a material adverse impact on our revenues and results of operations.

We are dependent
on our management and research and development teams, and the loss of any key member of either of these teams may prevent us from executing our business strategy.

Our future success depends in a large part upon the continued services of our executive officers and other key personnel. In particular, Shawn McCreight, our founder, Chairman and Chief Technology
Officer, has been significantly responsible for the development of our products. In addition, Victor Limongelli, our President and Chief Executive Officer, is responsible for a number of our significant strategic initiatives. We are also
substantially dependent on the continued services of our existing research and development personnel. We have fewer research and development employees than many competitors of comparable size due to the high degree of expertise required to work with
our complex technology and our stringent hiring standards. The loss of one or more of our key employees, and in particular our research and development personnel, could seriously harm our business development, culture and strategic direction. We do
not maintain key person life insurance policies on any of our executives. Any key person life insurance policy we maintain now or in the future would not be sufficient to cover the loss of any of our key personnel and any such loss could seriously
harm our business and our ability to execute our business strategy. We have agreements that provide severance benefits to each of our Named Executive Officers. Our failure to retain these key employees could negatively impact our ability to execute
our business strategy.

Changes or reforms in the law or regulatory landscape could diminish the need for our solutions,
and could have a negative impact on our business.

One factor that drives demand for our products and services is the
legal and regulatory framework in which our customers operate. Laws and regulations are subject to drastic changes and these could either help or hurt the demand for our products. Thus, certain changes in the law and regulatory landscape, such as
tort law or legislative reforms that limit the scope and size of electronic discovery requests or the admissibility of evidence generated by such requests, as well as court decisions, could significantly harm our business. Changes in domestic and
international privacy laws could also affect the demand and acceptance of our products, and such changes could have a material impact on our revenues.

We face direct and indirect competition from other software companies, as well as other companies that provide training, consulting and certification services in computer forensics, which could
limit our growth and market share.

The markets for our software products and services are competitive, highly
fragmented and subject to rapidly changing technology, shifting customer needs and frequent introductions of new products and services. We expect the intensity of competition to increase in the future as new companies enter our markets, existing
competitors develop stronger capabilities and we expand into other markets. Many of our current competitors have longer operating histories, greater name recognition, access to larger customer bases and substantially more extensive resources than we
have. They may be able to devote greater resources to the development, promotion and sale of their products than we can to ours, which could allow them to respond more quickly than we can to new technologies and changes in customer needs and achieve
wider market acceptance. Because the barriers to entry into software industry segments are generally low, we expect to continue to face competition from new entrants, particularly as we expand into other segments of the software industry.

Several competing companies provide digital investigation software and applications that directly compete or will compete
with our products, or offer solutions our products do not address. In addition, if the market for digital investigation software develops as we anticipate, other companies could enter this market through their own software development or through the
acquisition of one of our current competitors. If these companies are



15

##### Table of Contents

more successful in providing similar, better or less expensive digital investigation solutions compared to those that we offer, we could experience a decline in customers and revenue. These
companies include computer forensic companies, managed security services companies and consulting companies, such as the Big 4 consulting/accounting firms, many of which have substantially greater resources and customer bases than we do.
If our competitors are more successful than we are at generating professional services engagements, our growth rate or revenues may decline.

We also compete with companies or organizations that have developed or are developing and marketing software and services that diminish the need for our solutions or the budget available to our customers
to purchase our solutions. These companies include traditional security companies, data storage infrastructure and data archiving companies, information management, records management and internal IT organizations that develop their own solutions.

Computer hackers may damage our products, services and systems, which could cause interruptions in our service and harm
to our business, and hackers could gain access to our customers personal information which could result in the loss of existing clients, negative publicity and legal liability.

Computer hackers often attempt to access information, including personal information for purposes of identity theft and other criminal
activity. In particular, due to the nature of our business, the products and services that we offer and the industry in which we operate, we are more likely to be the target of computer hackers who would like to undermine our ability to offer the
products and services that we provide to our customers and possibly retaliate for the results or evidence that our products and services generate.

For example, in December 2005, we became aware of a security breach of our electronic records which contained, among other things, credit card information of approximately 5,000 customers. We promptly
notified law enforcement authorities as well as each of the customers whose information may have been compromised. We conducted a forensic examination of the incident and took a number of steps to both remediate the underlying cause and strengthen
our internal security system, including enhancing our internal information technology security department and redesigning our network architecture.

In early January 2006, the Federal Trade Commission (the FTC) commenced an inquiry into the December 2005 security breach. In September 2006, we executed a consent decree proposed by the FTC
that includes no monetary penalties. The consent decree finds that we failed to implement proper security measures to protect consumers data, and requires us to provide the FTC with initial and biennial third-party assessments of our IT
security for a period of 10 years. Additionally, the consent decree requires us to maintain a comprehensive IT security program, retain documentation of such program and provide notice of the consent decree to our executives and employees for a
period of 20 years. The FTC formally approved the consent decree on November 15, 2006 and subsequently issued a press release announcing the investigation and its conclusion. In April 2007, we received formal notice and service of the decree
from the FTC, effectively ending the inquiry. In October 2007, we timely filed the first compliance report required by the consent decree. In October 2009, we timely complied with our biennial monitoring and reporting responsibilities required by
the consent decree.

Given the incident, any subsequent breach of our security could be especially damaging to our reputation
and business and may result in monetary penalties if the FTC were to find that the circumstances that lead to the breach constituted a violation of our obligations under the consent decree.

In addition, from time to time we may be the targets of computer hackers who, among other things, create viruses to sabotage or otherwise
attack companies networks, products and services. For example, there was recently a spread of viruses, or worms, that intentionally deleted anti-virus and firewall software. Our products, networks, websites and systems, may be the target of
attacks by hackers. If successful, any of these events could damage our computer systems, force us to incur substantial costs to fix technical problems or result in hackers gaining access to our technical and other proprietary information, which
could harm our business and results of operations.

The complexity of accounting regulations and related interpretations and policies,
particularly those related to revenue recognition, could materially affect our financial results for a given period.

Although we use standardized sales agreements designed to meet current revenue recognition criteria under accounting principles generally accepted in the United States, we must often negotiate and revise terms and conditions of these
standardized agreements, particularly in multi-product license and services transactions and Pay-Per-Use agreements. As our transactions have increased in complexity, particularly with the sale of larger, multi-product licenses, negotiation of
mutually acceptable terms and conditions may require us to defer recognition of revenue on such licenses. We believe that we are in compliance with Accounting Standards Codification (ASC) Software IndustryRevenue Recognition topic
(ASC 985-605); however, more complex, multi-product license transactions require additional accounting analysis to account for them accurately. The professional technical guidance available regarding the application of software revenue
recognition is very conceptual, and silent to specific implementation matters. As a consequence of this, we have been required to make assumptions and judgments, in certain circumstances, regarding the application of software revenue recognition.
Incorrect assumptions or judgments as well as changes in, or clarification to accounting interpretations, could lead to unanticipated changes in our revenue accounting practices and may affect the timing of revenue recognition, which could adversely
affect our financial results for any given period. If we discover that we have interpreted and applied revenue recognition rules differently than prescribed by accounting principles generally accepted in the United States, we could be required to
devote significant management resources, and incur the expense associated with an audit, restatement or other examination of our financial statements.

Our effective tax rate may fluctuate, which could increase our income tax expense and reduce our net income.

In preparing our quarterly and annual consolidated financial statements, we estimate our income tax liability in each of the foreign and domestic jurisdictions in which we operate by estimating our actual
current tax exposure and assessing temporary differences resulting from differing treatment of items for tax and financial statement purposes. Our judgments, assumptions and estimates relative to the current provision for income tax take into
account current tax laws and our interpretation of current tax laws. Although we believe our judgments, assumptions and estimates are reasonable, changes in tax laws or our interpretation of tax laws and the resolution of any future tax audits could
significantly impact the amounts provided for income taxes in our consolidated financial statements.

We calculate our current
and deferred tax provisions based on estimates and assumptions that could differ from the actual results reflected in income tax returns filed during the subsequent year. Adjustments based on filed returns are generally recorded in the period when
the tax returns are filed and the global tax implications are known and could significantly impact the amounts provided for income taxes.

Our operating results and business would be seriously impaired if our revenues from our EnCase® Enterprise product were to decline.

Historically, we have derived substantially all of our license revenues from sales of our EnCase® Forensic and EnCase®
Enterprise product offerings. Although we have introduced new software modules, we expect that our EnCase®
Enterprise product offering will account for the largest portion of our software product revenues for the foreseeable future. Although we have no reason to believe that sales of EnCase® Forensic will decline in future periods, we believe that the degree of penetration for our EnCase® Forensic product in the law enforcement market makes it unlikely that revenue from sales of EnCase® Forensic will contribute dramatically to future revenue growth. For this reason, we are dependent on increased sales of EnCase® Enterprise and related products to drive future growth.

As a result, if for any reason revenue from our EnCase® Enterprise product offerings declines or does not increase as rapidly as we anticipate, our operating results and our prospects for growth will be significantly



17

##### Table of Contents

impaired. Further, if these products fail to meet the needs of our existing and target customers, or if they do not compare favorably in price and performance to competing products, our business
will be adversely affected.

We may be limited in our ability to utilize indirect sales channels, such as value-added
resellers, corporate resellers, professional services firms and other third-party distributors for the sale and distribution of our products, which may limit our ability to expand our customer base and our revenues.

We may be limited in our ability to market and distribute our products through value-added resellers, corporate resellers, professional
services firms and other third-party distributors, which we collectively refer to as third-party resellers, due to various factors. Due to the complex nature of our products, sales professionals generally require a significant amount of time and
effort to become sufficiently familiar with our products in order to be able to market them effectively, which makes our products unattractive to third-party resellers. In addition, our competitors include professional services organizations, such
as accounting, consulting and law firms, that would otherwise serve as a natural distribution channel for our products and related services.

Moreover, there is significant competition in our industry for qualified third-party resellers. Even if we were to succeed in attracting qualified and capable third-party resellers, we would likely have
relatively short-term contracts and no minimum purchase commitments with any existing and future third-party resellers. In addition, agreements with such third-party resellers are generally renewable annually, not exclusive and may be terminated by
either party within 30 days after the initial six-month period of the agreement, and with 30 days notice after the initial one-year period. If we are not able to recruit new qualified third-party resellers, our sales growth may be constrained and
our results of operations would suffer.

Our intellectual property rights are valuable, and if we are unable to protect
our proprietary technologies and defend infringement claims, we could lose our competitive advantage and our business could be adversely affected.

Our success depends in part on our ability to protect our proprietary products and services and to defend against infringement claims. If we are unable to do so, our business and financial results may be
adversely affected. To protect our proprietary technology, we rely upon a combination of copyright, patent, trademark and trade secret law, confidentiality restrictions in contracts with employees, customers and other third parties, software
security measures, and registered copyrights, trademarks and patents. If we fail to protect our intellectual property rights adequately, our competitors may gain access to our technology, and our business may be harmed. Any of our patents,
trademarks, copyrights or other intellectual property rights may be challenged by others or invalidated through administrative process or litigation proceedings. In addition, we may be unable to obtain patent, copyright or trademark protection on
products that we spend significant time and expense to develop in the future. Despite our efforts to protect our proprietary technology, unauthorized persons may be able to copy, reverse engineer or otherwise use some of our proprietary technology.
Furthermore, existing patent and copyright laws may afford only limited protection, and the laws of certain countries in which we operate do not protect proprietary technology as well as established law in the United States. For these reasons, we
may have difficulty protecting our proprietary technology against unauthorized copying or use. If any of these events happen, there could be a material adverse effect on the value of our proprietary technology and on our business and financial
results. In addition, litigation may be necessary to protect our proprietary technology. This type of litigation is often costly and time-consuming, with no assurance of success.

Claims that we misuse the intellectual property of others could subject us to significant legal liability and disrupt our business,
which could have a material adverse effect on our financial condition and results of operations.

Because of the nature
of our business, we may become subject to material claims of infringement by competitors and other third parties with respect to our current or future software applications, trademarks or other proprietary rights. The legal framework for software
patents is rapidly evolving and we expect that software



18



---

##### Table of Contents

developers will increasingly be subject to infringement claims as the number of software applications and competitors in our industry segment grows. In certain circumstances, the owners of
proprietary software could make copyright and/or patent infringement claims against us in connection with such activity. Any such claims, whether meritorious or not, could be time consuming and difficult to defend against, result in costly
litigation, cause shipment delays or require us to enter into royalty or licensing agreements with third parties, which may not be available on terms that we deem acceptable, if at all. Any of these claims could disrupt our business, make it
difficult to add or retain important features in our products and have a material adverse effect on our financial condition and results of operations.

If we are unable to continue to obtain government licenses, approvals or authorizations regarding the export of our products abroad, or if current or future export laws limit or otherwise restrict
our business, we could be prohibited from shipping our products to certain countries, which could negatively impact our business, financial condition and results of operations.

We must comply with United States laws regulating the export of our products to other countries. Our products contain encryption and
decryption technologies that require us to obtain certain licenses from the United States government in order to export certain of our products abroad. In addition, we are required to obtain licenses from foreign governments in order to import our
products into these countries. We cannot assure you that we will be successful in obtaining such licenses, approvals and other authorizations required from applicable governmental authorities to export our products. The export regimes and the
governing policies applicable to our business are subject to change, and we cannot assure you that such export approvals or authorizations will be available to us or for our products in the future. Our failure to receive any required export license,
approval or authorization would hinder our ability to sell our products and could negatively impact our business, financial condition and results of operations.

We have grown rapidly, and if we are not able to effectively manage and support our growth or retain and attract highly skilled employees, our business strategy might not succeed.

In the past we have grown rapidly and we will need to continue to grow in all areas of our operations to execute our
business strategy. Managing and sustaining our growth will place significant demands on management as well as on our administrative, operational, technical and financial systems and controls and other resources. We may not be able to expand our
product offerings, our customer base and markets, or implement other features of our business strategy at the rate or to the extent presently planned. In addition, our traditionally high level of customer service may suffer as we grow, which could
cause our software sales to suffer. If we are unable to successfully manage or support our future growth, we may not be able to maximize revenues or profitability.

In addition, in order to be able to effectively execute our growth plan, we must attract and retain highly qualified
personnel. We may need to hire additional personnel in virtually all operational areas, but primarily in selling and marketing, research and development, professional services, training and customer service. Competition in our industry for
experienced and qualified personnel in these areas is extremely intense, especially for software developers with high levels of experience in designing and developing software products and sophisticated technical sales people experienced in selling
our complex type of software products and selling into government agencies. In order to expand sales of EnCase®
Enterprise, we may need to continue to hire highly qualified commissioned sales personnel to directly target potential EnCase® Enterprise customers. These new commissioned sales personnel require several quarters of training and experience before being able to effectively market EnCase® Enterprise, and, as a result of these hires, our sales and marketing expense may increase at a greater rate than our
revenue, at least in the short term. The expense of hiring and training these commissioned sales personnel may never generate a corresponding increase in revenue. We may not be successful in attracting and retaining the necessary qualified personnel
that our growth plan requires. We have from time to time in the past experienced, and we expect to continue to experience in the future, difficulty in hiring and retaining highly skilled employees with appropriate qualifications. Many of the
companies with which



19

##### Table of Contents

we compete for experienced personnel have greater resources than we have. If we fail to attract new personnel or retain and motivate our current personnel, our business and future growth
prospects could be severely harmed.

We also believe that a critical contribution to our successful growth prior to the
recession in 2009, has been our corporate culture which fosters innovation, teamwork and excellence. As our organization grows and we are required to implement more complex organizational structures and institutional programs, we may find it
difficult to maintain the beneficial aspects of our corporate culture, which could negatively affect our ability to attract and retain qualified and experienced personnel and therefore our future success in continuing to maintain our rapid growth.

Our failure to offer high quality training and to attract and retain high quality training personnel could have a
material adverse effect on our sales of software applications and therefore have a negative impact on our business, financial condition and results of operations.

Our services offerings include training programs designed to instruct current and potential customers on the proper process of conducting a competent digital investigation and the most efficient operation
of our products. To a significant degree, the pool of potential users of our products is created by the training services we and our partners provide. Finding qualified third-party providers of training services for our complex software products is
difficult and time-consuming. If we or our partners do not effectively train our customers to properly use our software applications, or succeed in helping our customers quickly resolve post-deployment issues, it would adversely affect our ability
to sell additional software products to existing customers in the future and could harm our reputation with potential customers of software products. As a result, our failure to attract and maintain high quality training representatives and
personnel would have a material adverse effect on our sales of software applications and therefore negatively impact our business, financial condition and results of operations.

Our software applications may be perceived as, or determined by the courts to be, a violation of privacy rights. Any such perception
or determination could adversely affect our revenues and results of operations.

Because of the nature of digital
investigations, our potential customers and purchasers of our products or the public in general may perceive that use of our products for these investigations result in violations of individual privacy rights. In addition, certain courts,
legislative and regulatory authorities could determine that the use of our software solutions or similar products are a violation of privacy rights, particularly in jurisdictions outside of the United States. Any such determination or perception by
potential customers, the general public, government entities or the judicial system could harm our reputation and adversely affect the sales of our products and our results of operations.

Our business could be adversely affected based on the fact that, prior to June 2007, we entered into United States General Services
Administration (GSA) contracts as a procurement vehicle for federal government agencies that purchase certain of our products and services. These GSA contracts required that we provide our best corporate prices to the government agencies and give
the government agencies the right to conduct administrative audits of our performance under such GSA contracts. If we have an unfavorable administrative audit we may be required to reimburse the United States government for costs that they have
expended under such contracts.

Prior to June 2007, we have entered into GSA contracts in connection with the sale of
certain of our products and services. These GSA contracts were intended to facilitate efficient sales to government agencies and provide the government agencies with most-favored nation type pricing for the respective products and
services on a comparable basis with sales to other third parties. Since June 2007, we no longer contract directly with the GSA and operate under a Government Reseller Agreement with immixTechnology to sell our products via the immixTechnology
General Services Administration (GSA) contract to government customers.

The GSA and government agencies which purchase our
products and services pursuant to GSA contracts are permitted to conduct administrative audits of us as part of their routine audits and investigations of government



20



---

##### Table of Contents

contracts. For example, the GSA conducted an audit of Guidance for 2005 and issued us an administrative report card with a rating of successful. As part of the audit process, the GSA
or a government agency may review our performance under the contract, cost structure, including the cost of comparable products and services to third parties, and compliance with applicable laws, regulations and standards. The GSA or a government
agency may also review the adequacy of, and our compliance with, our internal controls systems and policies, including our purchasing, property, estimating, compensation and management information systems. If any of our pricing is found to be
improperly discounted to a specific contract, the revenue received by us may have to be refunded and an additional penalty may have to be paid by us.

Although our risk has been mitigated through our reseller arrangement, we remain subject to audit for periods prior to June 2007. A future audit with unfavorable results could materially affect our
competitive position and result in a material adjustment to our financial results. In addition, if a GSA or government agency audit uncovers improper or illegal activities on our part, we may be subject to civil and criminal penalties and
administrative sanctions, including, but not limited to, termination of existing contracts, forfeiture or disgorgement of profits, suspension of future payments owed, fines and suspension from doing future business with the federal government
through the GSA. Furthermore, our reputation could suffer serious or irreparable harm if allegations of impropriety were levied against us. If we were suspended from contracting through the GSA, our reputation or relationships with federal
government agencies were impaired, or the GSA or these agencies otherwise ceased doing business with us or significantly decreased the amount of business they do with us, our revenues and prospects would be materially harmed.

Our business depends, in part, on sales to governments and governmental entities and significant changes in the contracting or fiscal
policies of governments and governmental entities could have a material adverse effect on our business.

We derive a
portion of our revenues from contracts with federal, state, local and foreign governments and government agencies, and we believe that the success and growth of our business will continue to depend on our successful procurement of government
contracts. Accordingly, changes in government contracting policies or government budgetary constraints could directly affect our business, financial condition and results of operations. Among the factors that could adversely affect our business,
financial condition or results of operations are:



| |  |  | changes in fiscal policies or decreases in available government funding;
| | - |  | ------------------------------------------------------------------------



| |  |  | changes in government programs or applicable requirements;
| | - |  | ----------------------------------------------------------



| |  |  | the adoption of new laws or regulations or changes to existing laws or regulations;

| |  |  | changes in political or social attitudes with respect to security issues, computer crimes, discovery of computer files and digital investigations;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | potential delays or changes in the government appropriations process; and

These and other factors could cause governments and governmental agencies to refrain from purchasing the products and services that we offer
in the future, the result of which could have an adverse effect on our business, financial condition and results of operations. In addition, many of our government customers are subject to stringent budgetary constraints. The award of additional
contracts from government agencies could be adversely affected by spending reductions or budget cutbacks at government agencies that currently use or are likely to utilize our products and services.

Because we offer our EnScript® programming language for customization of and the creation of add-ons for EnCase®, customers or third-party programmers may be able to develop products that compete with our products or reduce the marketability or value of our products.

We have developed many of our major products, including EnCase® eDiscovery and EnCase® Information Assurance, to function as applications running on the EnCase® Enterprise platform. We
created these

applications using the EnScript® programming language. In
order to enhance the attractiveness of EnCase® to potential customers and position EnCase® as a standard software for digital investigations, we have made available without charge the EnScript® programming language, which permits users of EnCase® to develop customized add-on features for their own or others use, and we have trained our customers on how to write add-on programs using the EnScript® programming language, which is similar to Java or C++. As part of this strategy, we have encouraged the development
of an active community of EnScript® programmers similar to those which have emerged for other software products.
While we believe widespread use of our EnScript® programming language will ultimately create demand for our
products, customers in the past have developed, and may in the future develop, software for use with EnCase®
using the EnScript® programming language, rather than purchasing certain of our product offerings. Losses of
sales to potential customers could have a material adverse impact on our revenues and results of operations.

Our
success depends in part upon our ability to develop new products and enhance our existing products. Failure to successfully introduce new or enhanced products to the market may adversely affect our business, financial condition and results of
operations.

Our future success depends in part on our ability to develop enhancements to our existing products and to
introduce new products that keep pace with rapid technological developments and changes in customers needs. Although our products are designed to operate on a variety of network hardware and software platforms, we must continue to modify and
enhance our products to keep pace with changes in network platforms, operating systems, software technology and changing customer demands. We may not be successful in developing and documenting these modifications and enhancements or in bringing
them to market in a timely manner. Any failure of our products to operate effectively with future network platforms and technologies could reduce the demand for our products and result in customer dissatisfaction. In addition, our products
incorporate document viewer technology that we license from Oracle USA, Inc. Our license agreement with Oracle expires in November 2012. We may be unable to replace this technology if Oracle terminates this license agreement or it expires, or
if the Oracle technology becomes obsolete or incompatible with our products.

Furthermore, any new products that we develop
may not be released in a timely manner and may not achieve the market acceptance necessary to generate significant sales revenues. As a result, we may expend significant time and expense towards research and development for new or enhanced products,
which may not gain market acceptance or generate sufficient sales to offset the costs of research and development. If we are unable to successfully develop new products or enhance and improve our existing products, or if we fail to position or price
our products to meet market demand, our business, financial condition and results of operations will be adversely affected.

Errors in our products could adversely affect our reputation, result in significant costs to us, impair our ability to market our products and expose us to legal liability, any of which may adversely affect our operating results.

Products as complex as ours can contain undetected errors or failures. Despite extensive testing by us and by our
customers, we have in the past discovered errors in our software applications and will likely continue to do so in the future. As a result of past discovered errors, we experienced delays and lost revenues while we corrected the problems in those
software applications. In addition, customers in the past have brought to our attention bugs in our software exposed by the customers unique operating environments. Although we have been able to fix these software bugs in the past,
we may not always be able to do so in the future. In addition, our products may also be subject to intentional attacks by viruses that seek to take advantage of these bugs, errors or other weaknesses. Any of these events may result in the loss of,
or delay in, market acceptance of our products and services, which would seriously harm our sales, financial condition and results of operations.

Furthermore, we believe that our reputation and name recognition are critical factors in our ability to compete and generate additional sales of our products and services. Promotion and enhancement of our
brand

name will depend largely on our success in continuing to provide effective software applications and services. The occurrence of errors in our software applications or the detection of bugs by
our customers may damage our reputation in the market as well as our relationships with existing customers, which may result in our inability to attract or retain customers.

In addition, because our products are used in security and forensic functions that are often critical to our customers, the licensing and
support of our products makes us potentially subject to product liability claims. Any product liability insurance we carry may not be sufficient to cover our losses resulting from any such product liability claims. The successful assertion of one or
more large product liability claims against us could have a material adverse effect on our financial condition.

Incorrect or improper use of our products, our failure to properly train customers on how to utilize our software products or our failure to properly provide consulting and implementation services could result in negative publicity
and legal liability.

Our products are complex and are deployed in a wide variety of network environments. The proper
use of our software requires extensive training of the end user and, if our software products are not used correctly or as intended, inaccurate results may be produced. Our customers or our professional services personnel may incorrectly implement
or use our products. Our products may also be intentionally misused or abused by customers or non-customer third parties who obtain access and use of our products. Because our customers rely on our product and service offerings to manage a wide
range of sensitive investigations and security functions, the incorrect or improper use of our products, our failure to properly train customers on how to efficiently and effectively use our products or our failure to properly provide consulting and
implementation services to our customers may result in negative publicity or legal claims against us.

We cannot predict
our future capital needs and we may be unable to obtain additional financing to develop new products, enhance existing products, offer additional services or fund strategic acquisitions, the failure of which could have a material adverse effect on
our business, financial condition and results of operations.

We may need to raise additional funds in the future in
order to develop new products, enhance existing products, offer additional services or make strategic acquisitions of complementary businesses, technologies, products or services. Any required additional financing may not be available on terms
acceptable to us, or at all. If we raise additional funds by issuing equity securities, you will experience dilution of your ownership interest, which could be significant, and the newly-issued securities may have rights senior to those of the
holders of our common stock. If we raise additional funds by obtaining loans from third parties, the terms of those financing arrangements may include negative covenants or other restrictions on our business that could impair our operational and
financial flexibility and would also require us to incur additional interest expense. If additional financing is not available when required or is not available on acceptable terms, we may be unable to successfully develop or enhance our software
products and services through internal research and development or acquisitions in order to take advantage of business opportunities or respond to competitive pressures, which could negatively impact our software products and services offerings and
sales revenues, the failure of which could have a material adverse effect on our business, financial condition and results of operations.

Acquisitions that we may undertake in the future involve risks that could adversely affect our business, financial condition and results of operations.

We may pursue strategic acquisitions of businesses, technologies, products or services that we believe complement or expand our existing
business, products and services. Acquisitions involve numerous risks, including, but not limited to, the following:



| |  |  | diversion of managements attention during the acquisition and integration process;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | costs, delays and difficulties of integrating the acquired companys operations, technologies and personnel into our existing operations and
organization;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------

To date, we have not completed an acquisition. Any acquisitions of businesses, technologies, products or services that we may undertake in
the future may not generate sufficient revenues or cost-saving synergies necessary to offset the associated costs of the acquisitions or may result in other material adverse effects.

Our international sales and operations are subject to factors that could have an adverse effect on our business, financial condition
and results of operations.

We have significant sales and services operations outside the United States, and derive a
substantial portion of our revenues from these operations. We also continue to expand and diversify our international operations via a global distribution and reseller channel which will increase our global reach but do so via an indirect sales
model. For the years ended December 31, 2008 and 2009, we derived approximately 21% of our revenues from sales of products and services outside the United States.

Our international operations are subject to risks related to the differing legal, political, social and regulatory requirements and economic conditions of many countries, which risks include, but are not
limited to:



| |  |  | difficulties in staffing and managing our international operations;
| | - |  | -------------------------------------------------------------------



| |  |  | the fact that foreign countries may impose additional withholding taxes or otherwise tax our foreign income, impose tariffs or adopt other restrictions
on foreign trade or investment, including currency exchange controls;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the general economic conditions in the countries in which we operate could have an adverse effect on our earnings from operations in those countries;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the imposition of, or unexpected adverse changes in, foreign laws or regulatory requirements, including those pertaining to export duties and quotas,
trade and employment restrictions;

We may not continue to succeed in developing and implementing policies and strategies that will be

operations.

Insiders control a majority of our outstanding stock, and this may delay or prevent a
change of control of our company or adversely affect our stock price.

As of February 24, 2010, our executive
officers, directors and affiliated entities together beneficially own approximately 46.7% of our common stock outstanding, including 45.0% of our outstanding common stock held by our founder, Shawn McCreight, and his wife. As a result, these
stockholders may have control over matters that require approval by our stockholders, including the election of directors and approval of significant corporate transactions. Corporate actions favored by these stockholders might be taken even if
other stockholders oppose them. This concentration of ownership might also have the effect of delaying or preventing a change of control that other stockholders may view as beneficial.

Our charter documents and Delaware law may deter potential acquirers of our business and may thus depress our stock price.

Our amended and restated certificate of incorporation and our bylaws contain provisions that could delay or prevent a change
of control of our company that our stockholders might consider favorable. In addition, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which may discourage, delay or prevent certain business
combinations with stockholders owning 15% or more of our outstanding voting stock. These and other provisions in our charter documents may make it more difficult for stockholders or potential acquirers to initiate actions that are opposed by the
then-current board of directors, including delaying or impeding a merger, tender offer, or proxy contest or other change of control transaction involving our company. Any delay or prevention of a change of control transaction could cause
stockholders to lose a substantial premium over the then current market price of their shares.

The trading price of our
common stock is volatile.

The trading prices of the securities of technology companies have historically been highly
volatile. Accordingly, the trading price of our common stock has been subject to wide fluctuations since our initial public offering in December 2006. Factors that may affect the trading price of our common stock include:



| |  |  | variations in our financial results;
| | - |  | ------------------------------------



| |  |  | announcements of technological innovations, new solutions, pricing models, strategic alliances or significant agreements by us or by our competitors;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | recruitment or departure of key personnel;
| | - |  | ------------------------------------------



| |  |  | changes in the estimates of our financial results or changes in the recommendations of any securities analysts that elect to follow our common stock;
and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | market conditions in our industry, the industries of our customers and the economy as a whole.
| | - |  | ----------------------------------------------------------------------------------------------

In addition, if the market for software or other technology stocks or the stock market in general experiences continued or greater loss of
investor confidence, the trading price of our common stock could decline for reasons unrelated to our business or financial results. The trading price of our common stock might also decline in reaction to events that affect other companies in our
industry even if these events do not directly affect us.

Future sales of shares by existing stockholders could cause
our stock price to decline.

All of our outstanding shares are eligible for sale in the public market, subject in
certain cases to volume limitations under Rule 144 of the Securities Act of 1933, as amended. Also, shares subject to outstanding options and rights under our First Amended and Restated 2004 Equity Incentive Plan are eligible for sale in the public
market to the extent permitted by the provisions of various vesting agreements and Rules 144 and 701 under the Securities Act. If these shares are sold, or if it is perceived that they will be sold in the public market, the trading price of our
common stock could decline.

In addition, our founder, Shawn McCreight, and his wife, continue to hold a substantial
number of shares of our common stock. Sales by Mr. McCreight or his wife of a substantial number of shares, or the expectation that such sales may occur, could significantly reduce the market price of our common stock.

If our prior S Corporation election was not properly made and maintained, we would be liable for federal and certain state income
taxes.

In October 1998, we elected to be treated for federal income tax purposes as an S Corporation under
Subchapter S of the Internal Revenue Code. In addition, we elected or were otherwise treated as an S Corporation for certain state tax purposes. As an S Corporation, our earnings were included in the income of our stockholders for federal and
certain state income tax purposes. We filed an election to revoke our S Corporation status in December 2006. If our S Corporation election was not properly made and maintained prior to its revocation, we would be liable for federal and certain state
income taxes during prior open periods, together with interest thereon and, possibly, penalties. Such taxes and penalties may be material to our operating results.

|Item 2. | Properties

Our corporate
headquarters is located in Pasadena, California, where we lease approximately 68,590 square feet in two locations. We also lease an additional 53,065 square feet at facilities in Houston, Texas, Atlanta, Georgia, New York City, New York and near San
Francisco, California, Washington, D.C., Chicago, Illinois and London, England. We also maintain small regional facilities in Brazil and Singapore. Our leases expire at various points through 2015. We believe that our current facilities are suitable
and adequate to meet our current needs, and that suitable additional or substitute space will be available as needed to accommodate expansion of our operations.



|Item 3. | Legal Proceedings
|------- | -----------------

From
time to time, we may become involved in various lawsuits and legal proceedings that arise in the ordinary course of business. Litigation is subject to inherent uncertainties, and an adverse result in these or other matters may arise from time to
time that may harm our business. We are not currently aware of any such legal proceedings or claims that we believe will have, individually or in the aggregate, a material adverse effect on our business, financial condition or operating results.

In early January 2006, the Federal Trade Commission (the FTC) commenced an inquiry into the December 2005
security breach discussed in Risk FactorsComputer hackers may damage our products, services and systems, which could cause interruptions in our service and harm to our business, and hackers could gain access to our customers
personal information which could result in the loss of existing clients, negative publicity and legal liability. On September 20, 2006, we executed a consent decree proposed by the FTC that includes no monetary penalties. The consent
decree finds that we failed to implement proper security measures to protect consumers data, and requires us to provide the FTC with initial and biennial third-party assessments of our IT security for a period of 10 years. Additionally, the
consent decree requires us to maintain a comprehensive IT security program, retain documentation of such program and provide notice of the consent decree to our executives and employees for a period of 20 years. On April 9, 2007, the Company
received formal notice and service of the decree, which effectively ended the inquiry. On October 9, 2007, the Company timely filed the first compliance report required by the consent decree. In October 2009, we timely complied with our
biennial monitoring and reporting responsibilities required by the consent decree.

Our common stock has been traded on the NASDAQ Global Market under the symbol GUID since December 13, 2006. Prior to that
time, there was no public market for our common stock. The following table sets forth the range of high and low sales prices on the NASDAQ Global Market of the common stock for the periods indicated, as reported by NASDAQ.

As of
February 24, 2010, there were 22 holders of record of our common stock. On February 24, 2010, the last sale price reported on the NASDAQ Global Market for our common stock was $5.23 per share.

In October 1998, we elected to be treated for federal income tax purposes as an S Corporation under Subchapter S of the Internal
Revenue Code. In addition, we elected or were otherwise treated as an S Corporation for certain state tax purposes. We filed an election to revoke our S Corporation status in December 2006. As an S Corporation, we historically paid dividends to
our stockholders. We anticipate that any future earnings will be retained to finance continuing development of our business. Accordingly, we do not anticipate paying dividends on our common stock in the foreseeable future. Any determination to pay
dividends in the future will be at the discretion of our Board of Directors and will depend upon our results of operation, financial condition and other factors as the Board of Directors, in its discretion, deems relevant.

Purchases of Equity Securities by the Issuer

In August 2008, our Board of Directors authorized a program to repurchase shares of our common stock having an aggregate value of up to $8,000,000. As of December 31, 2009, we had approximately $6.2
million remaining under this authorization. The authorization allows us to repurchase our common stock from time to time through open market purchases and negotiated transactions, or otherwise. The timing, nature and amount of such transactions will
depend on a variety of factors, including market conditions, and the program may be suspended, discontinued or accelerated at any time. The sources of funds for the purchases under the remaining authorization are our existing cash and cash from
operations. Purchases are made in the open market, through block trades and other negotiated transactions. Repurchased shares are held in Treasury Stock and have not been retired.

In addition to the repurchased shares outlined below, the Company withheld approximately 52,800 and 13,200 common shares in 2009 and 2008,
respectively, from employees to satisfy their personal income tax withholding requirements upon the vesting of restricted stock awards issued under our equity compensation plans. The Company may engage in similar transactions from time to time
related to future vesting of employee restricted stock awards.

filed an election to revoke our S Corporation status on December 11, 2006. Pro forma net (loss) income data is unaudited and reflects the income tax expense that would have been recorded had we not been exempt from paying income taxes due to

|Item 7. | Managements Discussion and Analysis of Financial Condition and Results of Operations
|------- | -------------------------------------------------------------------------------------

The following discussion of our financial condition and results of operations should be read together with the financial statements and
related notes that are included elsewhere in this Annual Report on Form 10-K. This discussion may contain forward-looking statements based upon current expectations that involve risks and uncertainties. Our actual results may differ materially from
those anticipated in these forward-looking statements as a result of various factors, including those set forth under Risk Factors or in other parts of this Annual Report on Form 10-K.

Overview

We develop and provide the leading software solutions for digital investigations, including EnCase® Enterprise, a network-enabled product primarily for corporations and government agencies, and EnCase® Forensic, a desktop-based
product primarily for law enforcement agencies and digital investigators.

We were incorporated and commenced operations in
1997. From 1997 through 2002, we generated a substantial portion of our revenues from the sale of our EnCase® Forensic products and related services. We

have experienced increases in our revenue as a result of the release of our EnCase® Enterprise products in late 2002, which expanded our customer base into corporate enterprises and federal
government agencies. In addition, the releases of our EnCase® eDiscovery solution in late 2005 and EnCase® Information Assurance solution in late 2006 (which was replaced by our EnCase® Cybersecurity solution in 2009) have increased our
average transaction size. We anticipate that sales of our EnCase® Enterprise products and related services, in
particular our EnCase® eDiscovery and EnCase® Cybersecurity solutions, will comprise a substantial portion of our future revenues.

Important Factors Affecting Our Results of Operations

There are a number of trends that may affect our
business and our industry. We have identified factors that we expect to play an important role in our future growth and profitability. Some of these trends or other factors include:



| |  |  | Legislative and regulatory developments.Our digital investigation solutions allow law enforcement agencies, government organizations and
corporations to conduct investigations within the legal and regulatory framework. Historically, the implementation of new laws and regulations surrounding digital investigations has helped create demand for our products. Future changes in applicable
laws or regulations could enhance or detract from the desirability of our products.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Information technology budgets.Deployment of our solutions may require a substantial capital expenditure by our customers. Budgets for
information technology-related capital expenditures at corporations and all levels of government organizations are typically cyclical in nature, with generally higher budgets in times of improving economic conditions and lower budgets in times of
economic slowdowns.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Law enforcement agency budgets. We sell our EnCase® Forensic products and training services primarily to law enforcement agencies. Because
of the limited nature of law enforcement budgets, funds are typically initially allocated toward solving issues perceived to be the most pressing. Sales of our products could be impacted by changes in the budgets of law enforcement agencies or in
the relative priority assigned to digital law enforcement investigations.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Prevalence and impact of hacking incidents and spread of malicious software. The increasing sophistication of hacking attacks on government and
private networks and the global spread of malicious software, such as viruses, worms and rootkits, have increased the focus of corporations and large government organizations on digital investigations and other aspects of network security, which
has, in turn, increased demand for our products. Future changes in the number and severity of such attacks or the spread of malicious software could have an effect on the demand for our products.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Seasonality in revenues. We experience seasonality in our revenues, with the third and fourth quarters typically having the highest revenues for
the year. We believe that this seasonality results primarily from our customers budgeting cycles. The federal government budget year ends in the third calendar quarter of the year and a majority of corporate budget years end in the fourth
calendar quarter of the year. In addition, our customers also tend to make software purchases near the end of a particular quarter, which tends to make our revenues for a particular period unpredictable for a significant portion of that period. We
expect that this seasonality within particular years and unpredictability within particular quarterly periods will continue for the foreseeable future.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Amount of commercial litigation. Because commercial litigation often involves eDiscovery, an increase in commercial litigation could increase
demand for our products and services, while a decrease in commercial litigation could decrease demand.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Summary of 2009
Results of Operations

Our total revenue for the fiscal year ended December 31, 2009 was $74.9 million, a decrease of
$16.6 million, or 18%, from last fiscal year. Product revenue was $34.1 million for the fiscal year ended December 31,

##### Table of Contents

2009, a decrease of $14.2 million, or 29%, from last fiscal year. Services and maintenance revenue was $40.8 million for the fiscal year ended December 31, 2009, a decrease of $2.4 million,
or 6%, from last fiscal year. The decrease in our revenue was primarily due to the overall economic environment, and the resulting decreases in and/or postponements of IT spending by our customers. Sales to our government customers were also
impacted by the delay in approval of the 2010 federal budget.

Our net loss for the fiscal year ended December 31, 2009
was $13.9 million, or $0.60 per share, compared to a net loss of $10.6 million, or $0.46 per share, for last fiscal year. Our profitability is primarily dependent upon revenue from sales of our software solutions. Profitability is also affected by
the costs and expenses associated with developing our software. Cost of revenues decreased by $5.3 million, or 20%, in the fiscal year ended December 31, 2009 compared to the prior fiscal year. The decrease was primarily the result of cost
reductions and lower sales of products. Operating expenses decreased by $6.3 million, or 8%, in 2009 as compared to 2008, due primarily to the reduction in headcount and reduced general and administrative costs.

During fiscal year 2009, we launched EnCase® Portable, a data acquisition solution that enables customers to leverage the search and
acquisition capabilities of EnCase® software in a wide range of field applications through the use of a portable device. We also launched EnCase® Cybersecurity, which provides the ability to identify and analyze undiscovered threats, such as
polymorphic or metamorphic malware, and other advanced hacking techniques that evade traditional network or host-based defenses and includes investigative capabilities that target confidential or sensitive data and risk mitigation by remediating
sensitive data from unauthorized locations.

Sources of Revenue

Our sales transactions typically include the following elements: a software license fee paid for the use of our products under a perpetual
license term, or for a specific term; an arrangement for first-year support and maintenance, which includes unspecified software updates, upgrades and post-contract support; and professional services for installation, implementation, consulting and
training. We derive the majority of our revenues from sales of our software products. We sell our products and services primarily through our direct sales force and in some cases we utilize resellers.

We recognize revenue in accordance with the Accounting Standards Codification (ASC) Software IndustryRevenue
Recognitiontopic (ASC 985-605), which, if revenues are to be recognized upon product delivery, requires among other things vendor-specific objective evidence of fair value, or VSOE, for each undelivered element of multiple element customer
contracts.

Product Revenues

We generate product revenues principally from two product categories: EnCase® Enterprise and EnCase® Forensic. In 2009, we redefined the categories that made up our product revenues. Our EnCase® Enterprise
now includes perpetual licenses and Pay-Per-Use fees related to our eDiscovery, Legal Hold, Data Audit & Policy Enforcement, EnCase® Cybersecurity and OEM add-on products. EnCase® Forensic now includes revenues related to EnCase® Portable, Neutrino® mobile
forensic device, Field Intelligence Model and our Premium License Support Program product, which is sold on a subscription basis for a term of one or three years. In addition, we sell third party forensic hardware as a convenience to our customers,
which comprises Other product revenue. In prior years, Other had previously included OEM, Neutrino® and Field
Intelligence Model. For comparability purposes, we have restated 2008 and 2007 segments as defined above; however total product revenues remains unchanged as a result of the reclassification. During the first two quarters of each fiscal year, we
typically experience our lowest levels of product sales due to the seasonal budgetary cycles of our customers. The third quarter is typically the strongest quarter for sales to our federal government customers. Typically, sales to our corporate
customers are highest in the fourth quarter.

Product revenues decreased by $14.2 million, or 29%, for the
fiscal year ended December 31, 2009 from the prior fiscal year, primarily due to a $12.7 million reduction in EnCase® Enterprise license revenues. We believe the decrease in EnCase® Enterprise license revenue was due to the depressed economic environment and the resulting negative impact on customers IT purchases and the delay of government
deals which were contingent upon final approval of the new fiscal year 2010 federal budget. EnCase® Forensic
revenue decreased by $1.3 million, or 9%, for the fiscal year ended December 31, 2009 from the prior fiscal year. The decrease in 2009 for forensic revenue is attributable to reduced spending by state and local government agencies, as well as
law enforcement and other federal agencies.

Product revenues increased by $4.0 million, or 9%, in 2008
over 2007, with that growth driven by a $2.4 million revenue increase from our EnCase® Forensic product
line and $1.5 million increase from our EnCase® Enterprise product line. The increase in forensic revenue is
attributable to a larger number of governmental contracts completed during 2008. EnCase® Enterprise revenue grew
as a result of increased market penetration and the introduction of our eDiscovery product Pay-Per-Use pricing during the second half of 2008

Services and Maintenance Revenues

Services and maintenance revenues decreased $2.4 million, or 6%, for the
fiscal year ended December 31, 2009, compared to 2008 and increased $6.3 million compared to 2007. Revenue for the professional services segment decreased by $3.6 million, or 26%, compared to prior fiscal year. Professional services
revenue was impacted by the reduced demand for both implementation services and eDiscovery services as a result of the decline in sales compared to the prior years. Training services revenue decreased by $2.2 million, or 22%, for the fiscal
year ended December 31, 2009, compared to the prior fiscal year, due to reductions in our customers travel and training budgets during the economic downturn. Maintenance and other revenue increased by $3.5 million, or 18%, for the fiscal
year ended December 31, 2009 compared to 2008, and $9.0 million compared to 2007, as a result of the overall increase in our installed product base and a high annual renewal rate by customers desiring continuing maintenance support on our
products.

Cost of Product Revenues

Cost of software product revenues consists principally of the cost of producing and distributing our software, including the cost of compact discs, packaging, shipping, customs duties, and, to a lesser
extent, compensation and related overhead expenses. While these costs are primarily variable with respect to sales volumes, they remain very low in relation to the revenues generated and result in higher gross margins than our services and training
businesses. Our gross margins can be affected by product mix, as our EnCase® Enterprise products are generally higher margin products than our EnCase® Forensic products.

Cost of product revenues decreased by $0.3 million, or 11%, for the fiscal year ended December 31, 2009, compared to 2008, and remained
flat with 2007. The decrease in 2009 was a result of reduced custom duty and shipping costs due to electronic delivery of product and reduced cost of printed materials. Product gross margin decreased slightly to 91.8% in 2009 from 93.5% in 2008 due
to the introduction of EnCase® Portable and a higher mix of forensic versus enterprise sales.

Cost of Services and Maintenance
Revenues

The costs of professional services and training revenues are largely comprised of employee compensation,
including share-based compensation, related overhead expenses, and travel and facilities costs. The cost of maintenance revenue is primarily outsourced, but also includes employee compensation costs for customer technical support and related
overhead costs.

Total cost of services and maintenance revenues decreased by $4.9 million, or 22%, for the fiscal year ended
December 31, 2009, compared to 2008, and $1.4 million, or 7%, compared to 2007. This reduction in cost of services and maintenance revenues is due to an overall decline in services and maintenance revenues and lower headcount. In 2009, we
reduced headcount in our professional services division which increased gross margins. In 2008, headcount and related expenses of our professional services division were higher which resulted in lower gross margins.

##### Table of Contents

Overall, services and maintenance gross margin increased to 56.2% from 47.2% in 2008, and
44.2% in 2007. The year-over-year increase in maintenance revenues has resulted in a higher mix of maintenance revenues when compared to total revenues increasing from 17.4% in 2007 to 21.1% in 2008 and 30.4% in 2009. The gross margin on maintenance
and other revenue increased to 90% from approximately 86%87% in the prior two years due to continued high renewal rates with our existing customer base and lower costs associated with maintenance renewals.

Selling and Marketing Expenses

Selling and marketing expenses consist primarily of personnel costs and costs related to our sales force and marketing staff. Selling and marketing expenses also include expenses relating to advertising,
brand building, marketing promotions and trade show events (net of amounts received from sponsors and participants), product management, travel and allocated overhead.

Although we expense our sales commissions at the time the related sale is invoiced to the client, revenues from our
EnCase® Enterprise term licenses, EnCase® Forensic product, Premium License Support Program, Neutrino®,
the Annual Training Passport, and our consulting, maintenance and implementation services are recognized over the relevant performance or license period. Accordingly, we generally experience a delay between when we experience increased selling and
marketing expenses and when we recognize a portion of the corresponding revenue. We employed approximately 119 sales and marketing personnel at the end of 2009, 150 at the end of 2008 and 135 at the end of 2007.

Selling and marketing expenses in 2009 decreased $3.2 million, or 8%, compared to 2008, and increased $3.5 million, or 11%, compared to
2007. The change in expense is a result of the fluctuations in headcount year over year, as well as the variability in sales commission expense associated with the increase or decrease in product revenue.

Research and Development Expenses

Research and development expenses consist primarily of compensation, including share-based compensation, and related overhead expenses. In
order to develop new product offerings, continue developing existing products and improve quality assurance, we increased the number of research and development personnel that we employ to 84 in 2009 from 75 in 2008 and 55 in 2007.

Research and development expenses increased $1.2 million, or 9%, for the fiscal year ended December 31, 2009, compared to 2008, and
increased $5.2, or 57%, compared to 2007. The higher expenses were driven primarily by increases in headcount and other employee-related expenses and the number of products in development.

General and Administrative Expenses

General and administrative expenses consist of personnel and related costs for accounting, legal, information systems, human resources and other administrative functions. In addition, general and administrative expenses include
professional service fees, bad debt expense, other corporate expenses and related overhead. As a result of process efficiencies and automation, we decreased the number of general and administrative personnel that we employ to 61 in 2009 from 73 in
2008, and remained comparable to headcount levels in 2007.

General and administrative expenses decreased by $4.6 million, or
25%, for the fiscal year ended December 31, 2009 compared to 2008, and $1.1 million, or 8%, compared to 2007. The decline was attributable to lower headcount and related expenses, reduction in legal expenses, audit, tax and Sarbanes-Oxley costs
due to the implementation of a new ERP system and lower bad debt expense compared to the prior fiscal year.

Depreciation and Amortization
Expenses

Depreciation and amortization expenses consist of depreciation and amortization of our leasehold improvements,
furniture and computer hardware and software. In 2009, 2008 and 2007, we invested $2.6 million, $6.0 million and $8.6 million, respectively, in capital equipment and leasehold improvements, resulting in significant increases in depreciation and
amortization expense. Depreciation and amortization expense in 2009 increased $0.3 million, or 8%, compared to 2008, and $1.0 million, or 28%, compared to 2007, primarily due to the implementation of our new enterprise resource planning (ERP) system
that was implemented in the first quarter of 2009.

Other Income and Expense

Other income and expense consists of interest income, interest expense and other income (expense), net. Interest income consists of interest
earned on cash and cash equivalents balances. Other income (expense), net consists of gains and losses on the disposal of fixed assets and other miscellaneous income and expense items. In 2009, interest income decreased by $0.6 million, or 88%,
compared to 2008, and $1.4 million, or 94%, compared to 2007. The decrease was due primarily to lower market rates earned on our cash and cash equivalents compared to prior years.

Income Tax Provision (Benefit)

The effective tax rate in years
2009, 2008 and 2007 was 2.6%, (22.8)% and (60.3)%, respectively. The effective tax rate in 2009 differed from the federal statutory rate of 34% primarily due to research and development credits, offset by the tax impact of certain share-based
compensation charges not deductible for tax, and the impact of providing a valuation allowance against deferred tax assets. The effective tax rates in 2008 and 2007 differed from the federal statutory rate of 34% primarily due to research and
development credits, offset by the tax impact of certain share-based compensation charges and the valuation allowance against deferred tax assets. See Note 5 to our Consolidated Financial Statements for additional information.

Liquidity, Capital Resources and Financial Condition

Since inception, we have largely financed our operations from our cash flow from operations. In December 2006, we issued and sold 3,250,000
shares of our common stock at $11.50 per share, for net proceeds of $34.8 million in our initial public offering. As of December 31, 2009, we had $36.6 million in cash and cash equivalents. We believe that our cash flow from operations and our
cash and cash equivalents are sufficient to fund our working capital and capital expenditure requirements for at least the next 12 months.

Changes in Cash Flow

We generate cash from operations primarily from cash collections related to the sale of
our products and services. Net cash provided by operating activities was $5.0 million in 2009, compared with net cash provided by operations of $4.2 million in 2008, and $8.5 million in 2007. The increase in cash provided by operations was primarily
a result of an $8.3 million decrease in accounts receivable in 2009, compared to a $5.3 million increase in accounts receivable in 2008 and a $4.5 million increase in 2007. Also impacting the cash provided by operations was an increase in
depreciation and amortization, offset by a lower increase in deferred revenue, lower share-based compensation and a larger loss in 2009 as compared to 2008. The decrease in accounts receivable was due primarily to lower sales and higher cash
collections in the fourth quarter of 2009 as compared to the fourth quarter of 2008. The first and fourth quarters of our fiscal year are our strongest quarters for cash collections, a consequence of the higher sales volumes typically experienced in
the third and fourth quarters.

Net cash used by investing activities decreased to $2.6 million in 2009 from $6.0 million in
2008 due to a decrease in capital expenditures in 2009. Capital expenditures during 2008 included the purchase of our new ERP system. In 2007, investing activities resulted in a $16.1 million use of cash due to the maturities of short term
investments. We presently expect capital expenditures to be between $1.3 million to $2.3 million in 2010, which we expect to fund from operating cash flows.

Net cash used by financing activities was $1.8 million in 2009, compared to cash provided by financing activities of $0.2 million in 2008 and $4.9 million in 2007. Cash used by financing activities in
2009 included $1.8 million of repurchases and withholdings of common stock, lower proceeds from stock option exercises and lower principal payments on our capital lease obligations compared to 2008 and 2007.

We maintain a $3.0 million revolving line of credit with a bank, which expires on April 30, 2010. Borrowings under this line of credit would
be collateralized by substantially all our assets. At December 31, 2009, there were no amounts outstanding under this line of credit. We maintain a $3.0 million revolving line of credit with a bank, which expires on April 30, 2010. Borrowings
under this line of credit would be collateralized by substantially all our assets. At December 31, 2009, there were no amounts outstanding under this line of credit. The line requires that we maintain certain financial covenants, and at June
30, 2009 we were in breach of the covenant that prohibited a cumulative net loss (excluding non-cash share-based compensation) in excess of $4.0 million during any one fiscal year. In July 2009, we executed an amendment to the credit agreement with
our bank, which increased the maximum allowable cumulative net loss under the covenant to $9.0 million (excluding non-cash share-based compensation) for the remainder of the 2009 fiscal year, and $4.0 million for any subsequent fiscal quarter. The
amendment also included a waiver of the covenant for the period ended June 30, 2009. In addition, borrowings under the amended credit agreement bear interest at one of the following rates (as selected by us): a rate equal to the banks
alternate base rate plus 2% or the banks LIBOR plus 3%. At December 31, 2009, we were in compliance with the covenants associated with the revolving line of credit.

Contractual Obligations and Commitments

We currently have no material cash commitments, except our normal recurring trade payables, expense accruals and leases, all of which are
currently expected to be funded through existing working capital and future cash flows from operations. At December 31, 2009, our outstanding contractual cash commitments were largely limited to our non-cancelable lease obligations, primarily
relating to office facilities, as follows:

Our
future capital requirements will depend on many factors, including our rate of revenue growth, the expansion of our selling and marketing activities, the timing and extent of research and development spending to support product development and
enhancement efforts, costs associated with expansion into new territories or markets, the timing of the introduction of new products and services and the enhancement of existing products and the continuing market acceptance of our products and
services. To the extent that our existing cash, cash from operations, or the availability of cash under our line of credit, are insufficient to fund our future activities and planned growth, we may need to raise additional funds through public or
private equity or debt financings. Although we are currently not a party to any agreement or letter of intent with respect to potential investments in, or acquisitions of, complementary businesses, products or technologies, we may enter into these
types of arrangements in the future, which could also require us to seek additional debt or equity financing. Additional funds may not be available on terms favorable to us, or at all. Furthermore, although we cannot accurately anticipate the effect
of inflation or foreign exchange markets on our operations, we do not believe these external economic forces have had, or are likely in the foreseeable future to have, a material impact on our results of operations.

Off-Balance Sheet Arrangements

As of December 31, 2009, we had no off-balance sheet arrangements as defined in Item 303(a)(4) of the Securities and Exchange Commissions Regulation S-K. We do not have material relationships or transactions with persons or
entities that derive benefits from their non-independent relationship with us or our related parties except as disclosed in this report.

Stock Repurchases

In August 2008, our Board of Directors authorized management to repurchase up to $8.0
million of our outstanding common stock. Under the authorization, the timing and actual number of shares subject to repurchase are at the discretion of management and are contingent on a number of factors, such as levels of cash generation from
operations, market conditions and our share price. Repurchased shares are held in Treasury Stock and have not been retired. As of December 31, 2009, we had approximately $6.2 million remaining under this authorization.

In addition to the shares we have repurchased on the open market, we withheld approximately 52,800 and 13,200 common shares in 2009 and
2008, respectively, from employees to satisfy their personal income tax withholding requirements upon the vesting of share awards issued under our equity compensation plans during the quarter. Withheld shares are held in Treasury Stock and have not
been retired. The Company may engage in similar transactions from time to time related to future vesting of employee restricted stock awards.

Critical Accounting Policies and Estimates

In preparing our financial statements, we make estimates,
assumptions and judgments that can have a significant impact on our net revenue, operating income or loss and net income or loss, as well as on the value of

##### Table of Contents

certain assets and liabilities on our balance sheet. We believe that the estimates, assumptions and judgments involved in the accounting policies described below and in Note 2 to our Consolidated
Financial Statements, included herein at Item 8, have the greatest potential impact on our financial statements, so we consider them to be our critical accounting policies and estimates. There have been no significant changes in those critical
accounting policies and estimates during the twelve months ended December 31, 2009.

Revenue Recognition

We recognize revenue in accordance with the Accounting Standards Codification (ASC) Software Industry- Revenue
Recognition topic (ASC 985-605). While the standard governs the basis for revenue recognition, in applying our revenue recognition policy we must determine which portions of our revenue should be recognized currently and which portions, if any,
should be deferred. In order to determine current and deferred revenue, we make judgments and estimates with regard to future deliverable products and services and the appropriate pricing for those products and services. In general, we recognize
revenue when persuasive evidence of an arrangement exists, we have delivered the product or performed the service, the fee is fixed or determinable and collectability is probable, as follows:



| |  |  | Persuasive evidence of an arrangement: If we either enter into contracts or receive written purchase orders issued by a customer that legally bind us
and the customer, we consider that as evidence of an arrangement.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Delivery: We deem delivery of products to have occurred when the title and risk of ownership have passed to the buyer. Services revenue is recognized
as services are performed.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Fixed or determinable fee: We consider the fee to be fixed or determinable if the fee is not subject to refund or adjustment and the payment terms are
within normal established practices. If the fee is not fixed or determinable, we recognize the revenue as amounts become due and payable, provided all other revenue recognition criteria have been met.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Collection is deemed probable: We conduct a credit review for all significant transactions at the time of the arrangement to determine the
credit-worthiness of the customer. Collection is deemed probable if we have a reasonable basis to expect that the customer will pay amounts under the arrangement as payments become due.

However, determining whether and when some of these criteria have been satisfied often involves assumptions and judgments that can have a
significant impact on the timing and amount of revenue reported. For example, for multiple element arrangements we must make assumptions and judgments in order to allocate the total purchase price (irrespective of invoiced allocations) among the
various elements we deliver, to determine whether undelivered services are essential to the functionality of the delivered products and services, to determine whether vendor-specific evidence (VSOE) of fair value exists for each
undelivered element and to determine whether and when each element has been delivered. The VSOE of fair value for all elements of an arrangement is based upon the normal pricing and discounting practices for those products and services when sold
separately and, for software license updates and product support services, is additionally measured by the renewal rate offered to the customer. If we were to change our pricing practices or any of our other assumptions or judgments in the future,
our future revenue recognition could differ significantly from our historical results.

Amounts for fees collected or invoiced
and due relating to arrangements when revenue cannot be recognized are reflected on our balance sheet as deferred revenue and recognized when the product is delivered or over the period in which the service is performed, in accordance with our
revenue recognition policy for such element. If we cannot objectively determine the fair value of any undelivered element included in bundled software and service arrangements, we defer revenue until all elements are delivered and services have been
performed, or until fair value can objectively be determined for any remaining undelivered elements. When the fair value of a delivered element has not been established, we use the residual method to record revenue if the fair value of all
undelivered elements is determinable. Under the residual method, the fair value of the undelivered elements is deferred and the remaining portion of the arrangement fee is allocated to the delivered elements and is recognized as revenue.

Product Revenue. The timing of product revenue recognition is dependent on the nature
of the product sold. Product arrangements comprising multiple deliverables, including software and hardware, are generally categorized into one of the following:



| |  |  | EnCase®
Enterprise, EnCase® eDiscovery, and related products: License revenue associated with these arrangements,
exclusive of amounts allocated to maintenance and other undelivered elements for which we have vendor-specific objective evidence (VSOE) of fair value, is recognized upon delivery, provided that all other criteria for revenue recognition
have been met.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | EnCase®
Forensic: License revenue from corporate customers, exclusive of amounts allocated to maintenance, for which we have VSOE of fair value, is recognized upon delivery, provided that all other criteria for revenue recognition have been met. Because
maintenance is included at no additional cost in governmental Forensic arrangements, VSOE of fair value for the maintenance element for governmental customers is indeterminable, so we allocate governmental Forensic product, services and maintenance
revenue ratably over the longer of the contractual maintenance period (12 months) or the implied maintenance period (typically, the longer of 12 months or product life) based on estimated fair values of the various components.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Premium License Support Program Solutions: The Premium License Support Program is a subscription arrangement entitling customers to receive unspecified
future products and post-contract customer support for a period of several years. Revenue resulting from Premium License Support Program arrangements is recognized ratably over the contractual period beginning with the delivery of the first product.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | EnCase®
Neutrino®: Our mobile device investigative solution is sold to Forensic customers with a related subscription
covering future adapters for newly issued cell phones. Revenue is recognized over the related subscription period. For Enterprise customers, EnCase® Neutrino® revenue is
recognized upon delivery, provided that all other criteria for revenue recognition have been met. Standard maintenance is charged to entitle customers to future cell phone adapters on an if-and-when available basis.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Hardware: Revenue associated with the sale of hardware is recognized upon shipment to the customer, provided that all other criteria for revenue
recognition have been met.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Services and Maintenance Revenue. Services and maintenance revenue
consists of professional services, training, and maintenance. Revenue from such services is generally recognized as the services are provided. Training revenues are either recognized on a per-class basis upon a participants attendance or, for
those customers who have subscribed to our Annual Training Passport program, revenue is recognized ratably over the annual period. We refer to revenue related to technical product support and software updates on a when-and-if available basis as
maintenance revenue, which is recognized ratably over the applicable contractual period. We determine the amount of maintenance revenue to be deferred through reference to substantive maintenance renewal provisions contained in each arrangement. We
consider substantive maintenance provisions to be provisions where the cost of the maintenance renewal, stated in the contract with our customer as a percentage ofthe product fee, is comparable to the normal pricing for maintenance-only
renewals. Substantially all of our customers purchase maintenance support when they acquire new software licenses and substantially all renew their maintenance support contracts annually or otherwise.

Share-Based Compensation

Effective January 1, 2006, we adopted the Compensation-Stock Compensation (ASC 718) topic and recognize share-based compensation expense for all share-based awards granted. Prior to the
adoption of Compensation- Stock Compensation, we used the minimum-value method for disclosure purposes. Since all options granted prior to January 1, 2006 were granted at exercise prices that were equal to the fair market value of the
underlying stock on the date of the grant, no share-based compensation for stock options was recorded in the accompanying financial statements prior to 2006 and we are not required to record compensation expense for



41



---

##### Table of Contents

stock options granted prior to January 1, 2006 unless the terms of those options are subsequently modified. Since adoption, we recognize share-based compensation expense for all share-based
awards granted after January 1, 2006 using the prospective transition method. Under that transition method, results for prior periods have not been restated.

With the exception of one option granted in December 2007 with market-based vesting conditions, which is discussed further in Note 10 to our Consolidated Financial Statements, we use the Black-Scholes
option pricing model to determine the grant date fair value of share-based payments and recognize that cost, net of an estimated forfeiture rate, as compensation expense on a straight-line basis over the vesting period. The determination of the
grant date fair value of share-based awards using that model is affected by our stock price as well as assumptions regarding a number of complex and subjective variables. These variables include the estimated number of years that we expect employees
to hold their stock options (the option term) and our expected stock price volatility, risk-free interest rates and dividends to be paid on our stock over that term.

The expected term (life) of stock option awards has been calculated using the simplified method because we lack sufficient
historical data to provide a reasonable basis to estimate the expected term. We lack this historical data because of two factors: first, our 2004 Equity Incentive Plan (the Plan) was adopted in 2004 and we do not have a sufficient
history of exercises and forfeitures over the typical 10-year life of our awards to predict future option holder behavior, which is critical in estimating an expected term for our options, and, second, we believe that our December 2006 initial
public offering has likely changed the historical patterns that were experienced during the brief period of time from the Plans adoption to our initial public offering. The volatility of our common stock is estimated at the date of grant based
on a weighted-average of the implied volatility of publicly traded 30-day to 270-day options on the common stock of a select peer group of similar companies (Similar Companies), the historical volatility of the common stock of Similar
Companies and, beginning in late 2007, the historical volatility of our common stock. The risk-free interest rate used in option valuation is based on the implied yield in effect at the time of each option grant, based on US Treasury zero-coupon
issues with equivalent expected terms. We use a dividend yield of zero in the Black-Scholes model, as we have no intention to pay any cash dividends on our common stock in the foreseeable future. Compensation-Stock Compensationalso requires
that we estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. We use historical data to estimate pre-vesting option forfeitures and record share-based
compensation expense only for those awards that are expected to vest. Quarterly changes in the estimated forfeiture rate can potentially have a significant effect on reported share-based compensation, as the cumulative effect of adjusting the
forfeiture rate for all expense amortization after January 1, 2006 is recognized in the period the forfeiture estimate is changed.

If we change the terms of our employee share-based compensation programs, refine future assumptions or if we change to other acceptable valuation models, the stock-based compensation expense that we
record in future periods may differ significantly from historical trends and could materially affect our results of operations. As of December 31, 2009, there was $15.0 million of total unrecognized compensation cost related to non-vested
share-based compensation that is expected to be recognized over a weighted-average period of 1.8 years. We expect to record approximately $5.0 million in share-based compensation in 2010 related to options and restricted stock awards outstanding at
December 31, 2009. See Note 10 to our Consolidated Financial Statements for further information regarding share-based compensation.

Allowance for Doubtful Accounts

We maintain an allowance for
doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. The allowance is established through a provision for bad debt expense. We determine the adequacy of this allowance by evaluating
individual customer accounts receivable, through consideration of the customers financial condition, credit history and current economic conditions. In addition, we analyze our historical credit loss history and apply these loss rates to our
current accounts receivable balances to verify the reasonableness of our allowance. If the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required
in the future, which would result in increased general and administrative expense.

Accounting for Income Taxes

In preparing our consolidated financial statements, we estimate our income tax liability in each of the foreign and domestic jurisdictions in
which we operate by estimating our actual current tax exposure and assessing temporary differences resulting from differing treatment of items for tax and financial statement purposes. Our judgments, assumptions and estimates relative to the current
provision for income tax take into account current tax laws, our interpretation of current tax laws and possible outcomes of audits conducted by foreign and domestic tax authorities. Reserves for income taxes to address potential exposures involving
tax positions that could be challenged by tax authorities will be established if necessary. Although we believe our judgments, assumptions and estimates are reasonable, changes in tax laws or our interpretation of tax laws and the resolution of any
future tax audits could significantly impact the amounts provided for income taxes in our consolidated financial statements.

We calculate our current and deferred tax provisions based on estimates and assumptions that could differ from the actual results reflected in income tax returns filed during the subsequent year. Adjustments based on filed returns are
generally recorded in the period when the tax returns are filed and the global tax implications are known, which can significantly impact our effective tax rate. Tax law and rate changes are reflected in the income tax provision in the period in
which such changes are enacted.

We record a valuation allowance to reduce our deferred tax assets to the amount that is more
likely than not to be realized. We consider all available evidence, both positive and negative, including historical levels of income, expectations and risks associated with estimates of future taxable income and ongoing prudent and feasible tax
planning strategies in assessing the need for a valuation allowance. In the event we were to determine that we would not be able to realize all or part of our net deferred tax assets in the future, an adjustment to the deferred tax assets would be
charged to earnings in the period in which we make such a determination. Likewise, if we later determine that it is more likely than not that the net deferred tax assets would be realized, we would reverse the applicable portion of the previously
provided valuation allowance.

On January 1, 2007, we adopted the accounting for uncertainty in income taxes which
contains a two-step approach to recognizing and measuring uncertain tax positions taken or expected to be taken in a tax return by determining if the weight of available evidence indicates that it is more likely than not that the tax position will
be sustained on audit, including resolution of any related appeals or litigation processes. The second step is to measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. The standard also
provides guidance on de-recognition, classification, accounting in interim periods and disclosure requirements for tax contingencies.

Commitments and Contingencies

We are subject to certain legal proceedings, as well as demands, claims
and threatened litigation that arise in the normal course of our business. We periodically evaluate all pending or threatened contingencies and commitments, if any, that are reasonably likely to have a material adverse effect on our operations or
financial position. We assess the probability of an adverse outcome and determine if it is remote, reasonably possible or probable as defined in accordance with the provisions of Contingencies (ASC 450). If management determines that it is
probable that an asset had been impaired or a liability had been incurred at the date of our financial statements, and the amount of the loss, or the range of probable loss can be reasonably estimated, we record an accrued liability and an expense
for the estimated loss. If no accrual is made for a loss contingency because one or both of the conditions pursuant to Contingencies are not met, but the probability of an adverse outcome is at least reasonably possible, we would disclose the
nature of the contingency, if material, and provide an estimate of the possible loss or range of loss, or state that such an estimate cannot be made.

Significant judgment is required in both the determination of probability and the determination of whether an exposure is reasonably estimable. Because of uncertainties related to these matters, any
accruals recorded are based on the best information available at the time. As additional information becomes available, we would

reassess the potential liability related to our pending claims and litigation and may revise our estimates favorably or unfavorably. Potential legal liabilities and the revision of estimates of
potential legal liabilities could have a material impact on our financial position and results of operations.

Recent Accounting
Pronouncements

Business Combinations (ASC 805):In January 2009, the Company adopted Business Combinationschanging the method of applying the acquisition method in a number of significant aspects. The standard also amends Income Taxes (ASC 740), such that adjustments made to valuation allowances on deferred taxes and acquired tax
contingencies associated with acquisitions that closed prior to the effective date of Business Combinations would also apply the provisions of Business Combinations. Effective on a prospective basis for all acquisitions on or after
January 1, 2009, the Company had adopted this guidance with no material impact to our consolidated financial statements. However, depending on the nature of an acquisition or the quantity of acquisitions entered into after the adoption,
Business Combinations may significantly impact the Companys consolidated financial statements resulting in generally lower earnings due to, among other items, the expensing of transaction costs and restructuring costs of acquired
companies.

Fair Value Measurements and Disclosures (ASC 820):In April 2009, the Financial Accounting Standards Board
(FASB) provided additional guidance in Fair Value Measurements and Disclosuresfor estimating fair value when the volume and level of activity for the asset or liability have significantly decreased and on identifying circumstances that
indicate a transaction is not orderly. The guidance emphasizes that the objective of a fair value measurement remains the same. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction
(that is, not a forced liquidation or distressed sales) between market participants at the measurement date under current market conditions. Effective for interim and annual reporting periods ending after June 15, 2009, the Company has adopted
this guidance with no material impact to our consolidated financial statements.

In August 2009, an update was made to Fair
Value Measurements and DisclosuresMeasuring Liabilities at Fair Value. This update permits entities to measure the fair value of liabilities, in circumstances in which a quoted price in an active market for an identical
liability is not available, using a valuation technique that uses a quoted price of an identical liability when traded as an asset, quoted prices for similar liabilities or similar liabilities when traded as assets or the income or market approach
that is consistent with the principles of Fair Value Measurements and Disclosures. Effective upon issuance, the Company has adopted this guidance with no material impact to our consolidated financial statements.

In September 2009, an update was made toFair Value Measurements and DisclosuresInvestments in Certain Entities that
Calculate Net Asset Value per Share (or Its Equivalent). This update permits entities to measure the fair value of certain investments, including those with fair values that are not readily determinable, on the basis of the net asset value
per share of the investment (or its equivalent) if such net asset value is calculated in a manner consistent with the measurement principles inFinancial Services-Investment Companies as of the reporting entitys measurement date. The
update also requires enhanced disclosures about the nature and risks of investments within its scope that are measured at fair value on a recurring or nonrecurring basis. Effective for interim and annual periods ending after December 15, 2009,
the Company has adopted this guidance with no material impact to our consolidated financial statements.

Subsequent Events
(ASC 855):In May 2009, the FASB issued Subsequent Events establishing general standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued. Subsequent
Events sets forth the period after the balance sheet date that entities should evaluate events of transactions that may occur for potential recognition or disclosure in the financial statements, circumstances under which entities should
recognize and the disclosures that should be made about events or transactions that occur after the balance sheet date. Effective for interim and annual periods ending after June 15, 2009, the Company has adopted this guidance with no material
impact to our consolidated financial statements.

Accounting Standards Codification (ASC):In June 2009, the FASB issued Statement
No. 168The FASB Accounting Standards Codification and the Hierarchy of Generally Accepted Accounting Principles a replacement of FASB Statement No. 162(the Codification).The Codification, which was
launched on July 1, 2009, became the single source of authoritative non-governmental US generally accepted accounting principles (GAAP), superseding various existing authoritative accounting pronouncements. The Codification eliminates the
GAAP hierarchy contained in Statement 162 and establishes one level of authoritative GAAP. All other literature is considered non-authoritative. Effective for interim and annual periods ending after September 15, 2009, the Company has adopted
this guidance with no material impact to our consolidated financial statements. References to various accounting pronouncements in the notes to our consolidated financial statements have been updated to reflect the codification references.

Revenue Recognition (ASC 605):In October 2009, an update was made to Revenue
RecognitionMultiple-Deliverable Revenue Arrangementsa consensus of the FASB Emerging Issues Task Force and the corresponding SoftwareCertain Revenue Arrangements That Include Software
Elementsa consensus of the FASB Emerging Issues Task Force.The update to Revenue Recognition removes the objective-and-reliable-evidence-of-fair-value criterion, replaces references to fair value with
selling price, provides a hierarchy that entities must use to estimate the selling price, eliminates the use of the residual method for allocation, and expands the ongoing disclosure requirements. The Software update changes the
accounting model for revenue arrangements and provides guidance on how a vendor should allocate arrangement consideration to deliverables that includes both tangible products and software. Both standards are effective prospectively for revenue
arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. The adoption of this standard is not expected to have a material impact to our consolidated financial statements.

Consolidations (ASC 810):In December 2009, the FASB issued the Improvements to Financial Reporting by Enterprises Involved with
Variable Interest Entitiesupdate changing how a reporting entity determines when an entity that is insufficiently capitalized or is not controlled through voting (or similar rights) should be consolidated. The determination of whether a
reporting entity is required to consolidate another entity is based on, among other things, the other entitys purpose and design and the reporting entitys ability to direct the activities of the other entity that most significantly
impact the other entitys economic performance. The update also requires a reporting entity to provide additional disclosures about its involvement with variable interest entities and any significant changes in risk exposure due to that
involvement that affects the reporting entitys financial statements. Effective January 1, 2010 for companies on a calendar-year basis, the Company has adopted this guidance with no material impact to our consolidated financial statements.

In January 2010, the FASB issued the Accounting and Reporting for Decreases in Ownership of a Subsidiarya Scope
Clarificationupdate clarifying the scope of a decrease in ownership of a subsidiary and requiring additional disclosures about the deconsolidation of a subsidiary or derecognition of a group of assets. Effective upon issuance and to be applied
retrospectively if a decrease in ownership of a subsidiary occurred, the Company has adopted this guidance with no material impact to our consolidated financial statements.

Equity and Earnings Per Share (ASC 505 and 260):In January 2010, the FASB issued the Accounting for Distributions to Shareholders
with Components of Stock and Cash update clarifying that entities should account for distributions to shareholders that offer them the ability to elect to receive their entire distribution in cash or shares of equivalent value (with a potential
limitation on the total amount of cash) as a share issuance that is reflected in earnings per share prospectively. This update eliminates the diversity in practice of entities reporting the distribution as a new share issuances while others
reporting as a stock dividend. Effective for interim and annual periods ending after December 15, 2009, the Company has adopted this guidance with no material impact to our consolidated financial statements.

|Item 7A. | Quantitative and Qualitative Disclosures about Market Risk
|-------- | ----------------------------------------------------------

Market Risk.Market risk represents the risk of loss that may impact our financial position due to adverse changes in the financial market prices and rates. Our market risk exposure is primarily a
result of fluctuations in foreign exchange rates, interest rates and credit risk. We do not hold or issue financial instruments for trading purposes.

Foreign Currency Risk.To date, substantially all of our international sales have been denominated in US dollars, and therefore, the majority of our revenues are not subject to foreign currency
risk. Our operating expenses and cash flows are subject to fluctuations due to changes in foreign currency exchange rates, but historically have had relatively little impact on our operating results and cash flows. A strengthening of the dollar
could make our products and services less competitive in foreign markets and therefore could reduce our revenues. In the future, an increased portion of our revenues and costs may be denominated in foreign currencies. We do not enter into derivative
instrument transactions for trading or speculative purposes.

Interest Rate Risk.Our investment portfolio, consisting
of highly liquid debt instruments of the US government at December 31, 2009, is subject to interest rate risk. The fair value of our investment portfolio would not be significantly impacted by either a 100 basis point increase or decrease in
interest rates due mainly to the short-term nature of the major portion of our investment portfolio.

Management Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f)
and 15d-15(f) under the Securities Exchange Act of 1934. Our internal control over financial reporting is 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. Our internal control over financial reporting includes those policies and procedures that:



| | (i) | pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets;
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting
principles, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and
| | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on
the financial statements.
| | ----- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

There are inherent limitations in the effectiveness of any system of internal
control, including the possibility of human error and the circumvention or overriding of controls. Accordingly, even an effective internal control system may not prevent or detect misstatements and can provide only reasonable assurance with respect
to financial statement preparation. 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.

Management assessed the effectiveness of our internal control over financial
reporting as of December 31, 2009, utilizing the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal ControlsIntegrated Framework. Based on the results of this assessment,
management (including our President and Chief Executive Officer and our Chief Financial Officer) has concluded that, as of that date, our internal control over financial reporting was effective.

The attestation report concerning the effectiveness of our internal control over financial reporting as of December 31, 2009, issued by
our independent registered public accounting firm, Deloitte & Touche LLP, appears on page F-2 of our Annual Report on Form 10-K.

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over
financial reporting during the fourth quarter of fiscal 2009 that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

REPORT OF INDEPENDENT REGISTERED

PUBLIC ACCOUNTING FIRM

To
the Board of Directors and Stockholders of

Guidance Software, Inc.

Pasadena, California

We have audited the accompanying consolidated balance
sheets of Guidance Software, Inc. and subsidiaries (the Company) as of December 31, 2009 and 2008, and the related consolidated statements of operations, stockholders equity, and cash flows for each of the three years in the
period ended December 31, 2009. Our audits also included the financial statement schedule listed in the Index at Item 15. We also have audited the Companys internal control over financial reporting as of December 31, 2009, 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 these financial statements and financial
statement schedule, 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 Report on Internal
Control over Financial Reporting. Our responsibility is to express an opinion on these financial statements and financial statement schedule and an opinion on the Companys internal control over financial reporting based on our audits.

We conducted our audits 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 the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all
material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. 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, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that
our audits provide a reasonable basis for our opinions.

A companys internal control over financial reporting is a
process designed by, or under the supervision of, the companys principal executive and principal financial officers, or persons performing similar functions, and effected by the companys board of directors, management, and other
personnel 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 the inherent limitations of internal control over
financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the
effectiveness of the internal control over financial reporting to future periods are subject to the risk that the 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 consolidated financial statements referred to above present fairly, in
all material respects, the financial position of Guidance Software, Inc. and subsidiaries as of December 31, 2009 and 2008, and the results of their operations and their cash flows for each of the three years in the period ended
December 31, 2009, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedule, when considered in relation to the basic consolidated financial statements
taken as a whole, presents fairly, in all material respects, the information set forth therein. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2009,
based on the criteria established in Internal ControlIntegrated Frameworkissued by the Committee of Sponsoring Organizations of the Treadway Commission.

Note
2.    Summary of Significant Accounting Policies

Basis of Presentation

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the
United States (GAAP), and include the accounts of Guidance and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.

Use of Estimates and Assumptions

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and judgments that affect the reported amounts of assets,
liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate these estimates, including those related to revenue recognition, share-based compensation, bad debts, income taxes,
commitments, contingencies and litigation. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results may differ from these estimates.

Cash and Cash Equivalents

We invest excess cash in money market funds and highly liquid debt instruments of the US government and its agencies. Highly liquid investments with stated maturities of three months or less from date of
purchase are classified as cash and cash equivalents.

Short-Term Investments

We account for our short-term investments, generally in marketable debt securities, in accordance with InvestmentsDebt and Equity
Securities (ASC 320). We determine the appropriate classification of our investments at the time of purchase and reevaluate such designation at each balance sheet date. In response to changes in the availability of and the yield on alternative
investments as well as liquidity requirements, we may sell these securities prior to their stated maturities. Typically, our short-term investments have been classified and accounted for as available for sale. These securities are carried at fair
value, based on market quotes, with the unrealized gains and losses, net of taxes, reported in accumulated other comprehensive income as a component of stockholders equity. When the fair value of an investment declines below its original cost,
we consider all available evidence to evaluate whether the decline is other-than-temporary. Among other things, we consider the duration and extent of the decline and economic factors influencing the markets. To date, we have had no such
other-than-temporary declines below cost. Any realized gains or losses on the sale of marketable securities are determined on a specific identification method and are reflected as a component of other expense. We did not have short-term investments
as of December 31, 2009 and 2008.

Fair Value of Financial Instruments

The carrying amounts of cash equivalents, accounts receivable, and accounts payable approximate fair value because of the short-term
maturities of these instruments. Based on borrowing rates currently available to us for borrowings with similar terms, the carrying values of our capital lease obligations also approximate fair value. Short-term investments are stated at fair value
based on market quotes.

Trade Receivables

Trade receivables are carried at original invoice amount less an allowance for doubtful accounts. The allowance is established through a
provision for bad debt expense. We determine the adequacy of this allowance by evaluating individual customer accounts receivable, through consideration of the customers financial condition, credit history and current economic conditions. In
addition, we analyze our historical credit loss history and apply these loss rates to our current accounts receivable balances to verify the reasonableness of our allowance. Trade receivables are written off when deemed uncollectible. A trade
receivable is generally considered past due if any portion of the receivable balance is outstanding for more than 45 days unless alternate terms are provided.

Inventory

Inventory is comprised of hardware and packaged software
and valued at the lower of cost or market, using the first-in first-out method.

Property and Equipment

The cost of property and equipment, less applicable estimated residual values, is depreciated over the shorter of
their estimated useful lives or the life of the lease (if applicable), on the straight-line method, from the date the specific asset is completed, installed, and ready for use, as follows:



|                               |  |                                       
|------------------------------ |  | --------------------------------------
|                               |  | Estimated Useful Life                 
|Leasehold improvements         |  | Shorter of life of asset or lease term
|Furniture and office equipment |  | 5 years                               
|Computer hardware and software |  | 2-7 years                             

Also included in
property and equipment is software maintained for internal use. Internally used software, whether purchased or developed, is capitalized and amortized using the straight-line method over an estimated useful life of two to seven years.

Impairment of Long-Lived Assets

We review our long-lived assets in accordance with Property, Plant and Equipment (ASC 360). Long-lived assets are reviewed for
impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the assets to future net
cash flows (undiscounted and without interest) expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair
value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. To date, we have not determined that any of our long-lived assets have been impaired.

Concentrations of Credit Risk

Financial instruments that potentially subject us to significant concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. We restrict our investments in cash
and cash equivalents to financial institutions, US government or federal agency instruments and obligations of corporations with high credit standing. At December 31, 2009, the majority of our cash balances were held at financial institutions
located in California, which accounts are insured by the Federal Deposit Insurance Corporation up to $250,000. Uninsured balances aggregate approximately $36.1 million as of December 31, 2009. At December 31, 2009, all of our cash
equivalents consisted of financial institution and US governmental obligations. We periodically perform credit evaluations of our customers and maintain reserves for potential losses on our accounts receivable. We do not believe we are subject to
concentrations of credit risk with respect to such receivables.

Revenue Recognition

We generate revenues principally from the sale of EnCase® Enterprise and EnCase®
Forensic software products. These proprietary products are generally sold with one to three years of maintenance, which can be renewed at a stated renewal rate. Revenue associated with the sale of software licenses is referred to as product revenue
and revenue associated with maintenance services is referred to as maintenance revenue. We also generate revenues from training courses and implementation and consulting services, in which we assist customers with the performance of digital
investigations and train their IT professionals in the use of our software products, which we collectively refer to as services revenue. To a lesser extent, we also generate revenues from the sale of our Premium License Support Program
(PLSP), Neutrino® product and EnCase® Portable, which are also included in product revenues.

We recognize revenue in accordance with the Accounting Standards Codification (ASC) Software Industry- Revenue Recognition topic (ASC 985-605). While the standard governs the basis for revenue
recognition, significant judgment and the use of estimates are required in connection with the allocation of revenue between product revenue and services and maintenance revenue, as well as the amount of deferred revenue to be recognized in each
accounting period.

Product revenue.The timing of product revenue recognition is dependent on the nature
of the product sold. Product arrangements comprising multiple deliverables including software and hardware are generally categorized into one of the following:



| |  |  | EnCase®
Enterprise Solutions: Revenue associated with these arrangements, exclusive of amounts allocated to maintenance and other undelivered elements, for which we have vendor-specific objective evidence (VSOE) of fair value, is recognized
upon delivery, provided that all other criteria for revenue recognition have been met.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | EnCase®
Forensic Solutions: Revenue from corporate customers, exclusive of amounts allocated to maintenance, for which we have VSOE of fair value, is recognized upon delivery, provided that all other criteria for revenue recognition have been met. We
allocate Forensic product, services and maintenance

| | revenue to government customers ratably over the longer of the contractual maintenance period (12 months) or the implied maintenance period (typically, the longer of 12 months or product life)
because VSOE of fair value of the maintenance element for governmental customers does not exist.
| | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Premium License Support Program (PLSP) Solutions: Revenue resulting from these arrangements is recognized ratably over the
three-year contractual period beginning with the delivery of the first product, as the PLSP is a subscription arrangement entitling the customer to receive unspecified future products and post-contract customer support.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | EnCase®
Neutrino® Solution: Our mobile device investigative solution is sold to Forensic customers with a
related subscription covering future adapters for newly issued cell phones. Revenue is recognized over the related subscription period. For Enterprise customers, EnCase® Neutrino® revenue is
recognized upon delivery, provided that all other criteria for revenue recognition have been met. Standard maintenance is charged to entitle customers to future cell phone adapters on an if-and-when available basis.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Hardware: Revenue associated with the sale of FastBloc® and other hardware is recognized upon shipment to the customer, provided that all other criteria for revenue recognition have been met.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Services and Maintenance Revenue.The majority of our consulting and implementation services are performed under per hour,
per disk drive or fixed fee arrangements. Revenue from such services is recognized as the services are provided or upon expiration of the contractual service period.

Training revenues are either recognized on a per-class basis upon a participants attendance or, for those customers who have subscribed to our Annual Training Passport program, revenue is recognized
ratably over the annual period.

Revenue related to technical support and software updates on a when-and-if available basis is
referred to as maintenance revenue. We recognize maintenance revenue ratably over the applicable maintenance period. We determine the amount of maintenance revenue to be deferred through reference to substantive maintenance renewal provisions
contained in multiple element arrangements. We consider substantive maintenance provisions to be provisions where the cost of the maintenance renewal, stated in the contract with our customer as a percentage of the product fee, is comparable to the
normal pricing for maintenance only renewals.

Revenue Recognition Criteria. Our basic revenue recognition
criteria are as follows:



| |  |  | Persuasive evidence of an arrangement: If we either enter into contracts or receive written purchase orders issued by a customer that legally
bind us and the customer, we consider that as evidence of an arrangement.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Product delivery: We deem delivery of a product to have occurred when the title and risk of ownership have passed to the buyer. Services revenue
is recognized as delivered.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Fixed or determinable fee: We consider the fee to be fixed or determinable if the fee is not subject to refund or adjustment and the payment
terms are within normal established practices. If the fee is not fixed or determinable, we recognize revenue as amounts become due and payable provided all other revenue recognition criteria have been met.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Collection is deemed probable: We conduct a credit review for all significant transactions at the time of the arrangement to determine the
credit-worthiness of the customer. Collection is deemed probable if we have a reasonable basis to expect that a customer will make pay amounts due under an arrangement as they become due.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Deferred Revenue

Deferred revenue consists primarily of payments received in advance of delivery of products and services associated with
the sale of our EnCase® Forensic product offerings and service offerings. Deferred revenue also includes revenue
related to undelivered elements that may or may not have been sold in conjunction with the sale of the EnCase®
Enterprise product for which VSOE of the undelivered elements exists.

Research and Development

We maintain a research and development staff to develop new products and enhance or maintain existing products. In accordance with
Software IndustryCosts of Software to Be Sold, Leased, or Marketed (ASC 985-20) software costs are expensed as incurred until technological feasibility of the software is determined and the recovery of the cost can reasonably be
expected, after which any additional costs are capitalized. To date, we have expensed all software development costs because the establishment of technological feasibility of products and their availability for sale has substantially coincided.

Commissions

We record sales commissions as earned, which is generally when the related revenue is recognized as described above.

Leases

We lease office facilities under operating leases and
certain equipment under capital leases, and account for those leases in accordance with Leases (ASC 840). For operating leases that contain rent escalation or rent concession provisions, the total rent expense during the lease term is
recorded on a straight-line basis over the term of the lease, with the difference between rent payments and the straight-line rent expense recorded as rent incentives in the accompanying consolidated balance sheets.

Advertising Costs

Advertising costs are charged to operations as incurred and were not significant for any period presented.

Accounting for Income Taxes

We account for income taxes in
accordance with Income Taxes (ASC 740). Deferred income taxes are recorded for the expected tax consequences of temporary differences between the tax bases of assets and liabilities for financial reporting purposes and amounts recognized for
income tax purposes. We record a valuation allowance to reduce our deferred tax assets to the amount of future tax benefit that is more likely than not to be realized.

On January 1, 2007, we adopted accounting for uncertainty in income taxes in accordance with Income Taxes, which requires companies to determine whether it is more likely than not that a tax
position will be sustained upon examination by the appropriate taxing authorities before any part of the benefit can be recorded in the financial statements. The standard also provides guidance on de-recognition, classification, accounting in
interim periods and disclosure requirements for tax contingencies. In addition, we have applied the standards in determining whether a tax position is effectively settled for the purpose of recognizing previously unrecognized tax benefits. The
impact of our adoption is more fully discussed in Note 5.

Foreign Currency Transactions

Assets and liabilities denominated in foreign currencies are remeasured at the balance sheet date. Resulting exchange rate gains or losses
are included as a component of current period earnings. We incurred approximately

##### Table of Contents

$31,000 and $500,000 of net foreign exchange losses in the years 2009 and 2008, respectively. In 2009, the US dollar weakened significantly against certain foreign currencies in which we had
assets denominated, resulting in a more favorable exchange rate loss in comparison to 2008.

Commitments and
Contingencies

We periodically evaluate all pending or threatened litigation and contingencies or commitments, if any,
that are reasonably likely to have a material adverse effect on our operations or financial position. In so doing, we assess the probability of an adverse outcome and determine if it is remote, reasonably possible or probable as defined in
accordance with the provisions of Contingency (ASC 450). If information available prior to the issuance of our financial statements indicates that it is probable that an asset had been impaired or a liability had been incurred at the date of
the financial statements, and the amount of the loss, or the range of probable loss can be reasonably estimated, then such loss is accrued and charged to operations. If no accrual is made for a loss contingency because one or both of the conditions
are not met, but the probability of an adverse outcome is at least reasonably possible, we disclose the nature of the contingency and provide an estimate of the possible loss or range of loss, or state that such an estimate cannot be made.

Recent Accounting Pronouncements

Business Combinations (ASC 805):In January 2009, the Company adopted Business Combinationschanging the method of applying the acquisition method in a number of significant aspects.
The standard also amends Income Taxes (ASC 740), such that adjustments made to valuation allowances on deferred taxes and acquired tax contingencies associated with acquisitions that closed prior to the effective date of Business
Combinations would also apply the provisions of Business Combinations. Effective on a prospective basis for all acquisitions on or after January 1, 2009, the Company had adopted this guidance with no material impact to our
consolidated financial statements.

Fair Value Measurements and Disclosures (ASC 820):In April 2009, the Financial
Accounting Standards Board (FASB) provided additional guidance in Fair Value Measurements and Disclosuresfor estimating fair value when the volume and level of activity for the asset or liability have significantly decreased and on
identifying circumstances that indicate a transaction is not orderly. The guidance emphasizes that the objective of a fair value measurement remains the same. Fair value is the price that would be received to sell an asset or paid to transfer a
liability in an orderly transaction (that is, not a forced liquidation or distressed sales) between market participants at the measurement date under current market conditions. Effective for interim and annual reporting periods ending after
June 15, 2009, the Company has adopted this guidance with no material impact to our consolidated financial statements.

In August 2009, an update was made to Fair Value Measurements and DisclosuresMeasuring Liabilities at Fair Value. This update permits entities to measure the fair value of liabilities, in circumstances in which a
quoted price in an active market for an identical liability is not available, using a valuation technique that uses a quoted price of an identical liability when traded as an asset, quoted prices for similar liabilities or similar liabilities when
traded as assets or the income or market approach that is consistent with the principles of Fair Value Measurements and Disclosures. Effective upon issuance, the Company has adopted this guidance with no material impact to our consolidated
financial statements.

In September 2009, an update was made toFair Value Measurements and
DisclosuresInvestments in Certain Entities that Calculate Net Asset Value per Share (or Its Equivalent). This update permits entities to measure the fair value of certain investments, including those with fair values that are
not readily determinable, on the basis of the net asset value per share of the investment (or its equivalent) if such net asset value is calculated in a manner consistent with the measurement principles inFinancial Services-Investment
Companies as of the reporting entitys measurement date. The update also requires enhanced disclosures about the nature and risks of investments within its scope that are measured at fair value on a recurring or nonrecurring basis.
Effective for interim and annual periods ending after December 15, 2009, the Company has adopted this guidance with no material impact to our consolidated financial statements.

Subsequent Events (ASC 855):In May 2009, the FASB issued Subsequent Events
establishing general standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued. Subsequent Events sets forth the period after the balance sheet date that entities
should evaluate events of transactions that may occur for potential recognition or disclosure in the financial statements, circumstances under which entities should recognize and the disclosures that should be made about events or transactions that
occur after the balance sheet date. Effective for interim and annual periods ending after June 15, 2009, the Company has adopted this guidance with no material impact to our consolidated financial statements.

Accounting Standards Codification (ASC):In June 2009, the FASB issued Statement No. 168The FASB Accounting Standards
Codification and the Hierarchy of Generally Accepted Accounting Principles a replacement of FASB Statement No. 162(the Codification).The Codification, which was launched on July 1, 2009, became the single source of
authoritative non-governmental US generally accepted accounting principles (GAAP), superseding various existing authoritative accounting pronouncements. The Codification eliminates the GAAP hierarchy contained in Statement 162 and establishes
one level of authoritative GAAP. All other literature is considered non-authoritative. Effective for interim and annual periods ending after September 15, 2009, the Company has adopted this guidance with no material impact to our consolidated
financial statements. References to various accounting pronouncements in the notes to our consolidated financial statements have been updated to reflect the codification references.

Revenue Recognition (ASC 605):In October 2009, an update was made to Revenue RecognitionMultiple-Deliverable
Revenue Arrangementsa consensus of the FASB Emerging Issues Task Force and the corresponding SoftwareCertain Revenue Arrangements That Include Software Elementsa consensus of the FASB
Emerging Issues Task Force.The update to Revenue Recognition removes the objective-and-reliable-evidence-of-fair-value criterion, replaces references to fair value with selling price, provides a
hierarchy that entities must use to estimate the selling price, eliminates the use of the residual method for allocation, and expands the ongoing disclosure requirements. The Software update changes the accounting model for revenue
arrangements and provides guidance on how a vendor should allocate arrangement consideration to deliverables that includes both tangible products and software. Both standards are effective prospectively for revenue arrangements entered into or
materially modified in fiscal years beginning on or after June 15, 2010. The adoption of this standard is not expected to have a material impact to our consolidated financial statements.

Consolidations (ASC 810):In December 2009, the FASB issued the Improvements to Financial Reporting by Enterprises Involved with
Variable Interest Entitiesupdate changing how a reporting entity determines when an entity that is insufficiently capitalized or is not controlled through voting (or similar rights) should be consolidated. The determination of whether a
reporting entity is required to consolidate another entity is based on, among other things, the other entitys purpose and design and the reporting entitys ability to direct the activities of the other entity that most significantly
impact the other entitys economic performance. The update also requires a reporting entity to provide additional disclosures about its involvement with variable interest entities and any significant changes in risk exposure due to that
involvement that affects the reporting entitys financial statements. Effective January 1, 2010 for companies on a calendar-year basis, the Company has adopted this guidance with no material impact to our consolidated financial statements.

In January 2010, the FASB issued the Accounting and Reporting for Decreases in Ownership of a Subsidiarya Scope
Clarificationupdate clarifying the scope of a decrease in ownership of a subsidiary and requiring additional disclosures about the deconsolidation of a subsidiary or derecognition of a group of assets. Effective upon issuance and to be applied
retrospectively if a decrease in ownership of a subsidiary occurred, the Company has adopted this guidance with no material impact to our consolidated financial statements.

Equity and Earnings Per Share (ASC 505 and 260):In January 2010, the FASB issued the Accounting for Distributions to Shareholders
with Components of Stock and Cash update clarifying that entities should account for distributions to shareholders that offer them the ability to elect to receive their entire distribution in cash or shares of equivalent value (with a potential
limitation on the total amount of cash) as a share issuance that is

reflected in earnings per share prospectively. This update eliminates the diversity in practice of entities reporting the distribution as a new share issuances while others reporting as a stock
dividend. Effective for interim and annual periods ending after December 15, 2009, the Company has adopted this guidance with no material impact to our consolidated financial statements.

Note 3.    Net Loss Per Share

Basic net loss per common share is calculated by dividing net loss by the weighted average number of common shares outstanding during the reporting period. Diluted net loss per share is calculated based
on the weighted average number of common shares and dilutive potential common shares outstanding during the period. Dilutive potential common shares consist of the shares issuable upon the exercise of stock options and upon the vesting of restricted
stock awards under the treasury stock method. In net loss periods, basic net loss per share and diluted net loss per share are identical since the effect of potential common shares is anti-dilutive and therefore excluded.

The following table sets forth the computation of basic and diluted net loss per share (in thousands, except per share data):

The valuation allowance at December 31, 2009 is $11.9 million. We have fully reserved against our
deferred tax assets based on our assessment of the future realizability of our deferred tax assets. In performing these assessments, we consider whether it is more likely than not that some portion or all of the deferred tax assets will not be
realized. We consider all available evidence, both positive and negative, including historical levels of income, expectations and risks associated with estimates of future taxable income and ongoing prudent and feasible tax planning strategies in
assessing the need for a valuation allowance.

At December 31, 2009, we have federal and state research and development
tax credit carryforwards of approximately $1.0 million and $0.6 million, respectively. The federal tax credits begin to expire in 2026. The state tax credit carryforward can be carried forward indefinitely.

As of December 31, 2009, our federal and state net operating loss carryforwards for income tax purposes are approximately $9.0 million
and $9.1 million, respectively, which expire through 2029.

We file income tax returns in the US federal jurisdiction,
and various state and foreign jurisdictions. We adopted the provisions of accounting for uncertain tax positions in accordance with the Income Taxes (ASC 740) topic on January 1, 2007 and, accordingly, performed a comprehensive review of
our uncertain tax positions as of that date. In this regard, an uncertain tax position represents our expected treatment of a tax position taken in a filed tax return, or planned to be taken in a future tax return, that has not been reflected in
measuring income tax expense for financial reporting purposes. A reconciliation of our total unrecognized tax benefits at December 31, 2008 and 2009 follows:

##### Table of Contents

During 2009, our liability for uncertain position was reduced to zero as a result of the
expiration of the statute of limitation in the particular filing jurisdiction. We do not expect there to be any material changes to our assessment of uncertain tax positions over the next twelve months. We are subject to routine corporate income tax
audits in the United States and foreign jurisdictions. The statute of limitations for our tax years 2006 through 2008 remains open for US purposes. Most foreign jurisdictions have statute of limitations that range from three to six years.

The liability for uncertain tax positions is recorded in accrued expenses in our consolidated balance sheets. We recognize
interest and penalties related to uncertain tax positions in the income tax provision. Interest and penalties are computed based upon the difference between our uncertain tax positions under Income Taxes and the amount deducted or expected to
be deducted in our tax returns. During 2009, 2008 and 2007, amounts accrued or paid for interest and penalties were insignificant.

Note
6.    Debt Obligations

We maintain a $3.0 million revolving line of credit with a bank which expires
on April 30, 2010. Borrowings under this line of credit would be collateralized by substantially all our assets. The line requires that we maintain certain financial covenants, and at June 30, 2009, we were in breach of the covenant that prohibited
a cumulative net loss (excluding non-cash share-based compensation) in excess of $4.0 million during any one fiscal year. In July 2009, we executed an amendment to the credit agreement with our bank, which increased the maximum allowable cumulative
net loss under the covenant to $9.0 million (excluding non-cash share-based compensation) for the remainder of the 2009 fiscal year, and $4.0 million for any subsequent fiscal quarter. The amendment also included a waiver of this covenant for the
period ended June 30, 2009. Borrowings under the amended credit agreement bear interest at one of the following rates (as selected by us): a rate equal to the banks alternate base rate plus 2% or the banks LIBOR plus 3%.

As of December 31, 2009, we were in compliance with the covenants associated with the revolving line of credit. There were no amounts
outstanding under this line of credit at December 31, 2009 or 2008.

Note 7.    Related Party Transactions

Certain of our stockholders guarantee substantially all of the obligations due under our capital and operating leases (Note
8).

Note 8.    Leases

We lease certain facilities and equipment under non-cancellable operating leases extending through 2015. The Company also subleases certain facilities under non-cancellable operating leases. The present
value of the remaining future minimum lease payments under capital leases is recorded in the consolidated balance sheets. The following is a schedule of future minimum lease payments under capital leases and operating leases (in thousands):

##### Table of Contents

Rent expense related to operating leases for 2009, 2008 and 2007 was $3,827,000, $4,265,000
and $4,110,000, respectively. Sublease rental income was approximately $131,000, $220,000 and $125,000 in 2009, 2008 and 2007, respectively. Substantially all of the capital leases and one operating lease are guaranteed by certain stockholders of
the Company.

Note 9.    Equity Incentive Plan

In 2004, our Board of Directors and stockholders approved the 2004 Equity Incentive Plan (the Plan). A total of 2,062,000 shares
of common stock were initially authorized and reserved for issuance under the Plan in the form of incentive and non-qualified stock options and stock purchase rights for restricted stock. The Plan was amended in 2005 to increase the number of shares
available for issuance to 3,977,000. In May 2006, the Board of Directors and stockholders approved the First Amended and Restated 2004 Equity Incentive Plan (the First Amended and Restated Plan), which amended and restated the Plan in
its entirety, and provided for increases in the number of shares available for issuance by an additional 1,127,000 shares on May 3, 2006, and an additional 828,000 shares on each of January 1, 2007, 2008 and 2009. At our 2008 Annual
Meeting of Stockholders, our stockholders approved an amendment to the First Amended and Restated Plan that accelerated to July 1, 2008 the automatic increase in the number of shares available under the plan that was scheduled to occur on
January 1, 2009. Employees, officers, consultants and directors are eligible to receive awards under the First Amended and Restated Plan, which is generally administered by the Compensation Committee of the Board of Directors, who determines
the terms and conditions of each grant.

At December 31, 2009, approximately 1,060,000 shares remain available for grant
as options or restricted stock awards under the First Amended and Restated Plan.

Stock Options

The terms of the options granted under the First Amended and Restated Plan are determined at the time of grant, and generally vest 25%
annually over a four-year service period and typically must be exercised within 10 years from the date of grant.

stock option activity follows:

##### Table of Contents

We define in-the-money options at December 31, 2009 as options that had exercise prices
that were lower than the $5.24 fair market value of our common stock at that date. The aggregate intrinsic value of options outstanding at December 31, 2009 is calculated as the difference between the exercise price of the underlying options
and the fair market value of our common stock for the 1,323,000 options that were in-the-money at that date, of which 1,026,000 were exercisable. The total intrinsic value of stock options exercised, determined as of the date of exercise, was
$32,000, $1,035,000 and $6,210,000 during the years 2009, 2008 and 2007, respectively.

The following summarizes information
about options unvested at December 31, 2009 that, based on current forfeiture rates, are expected to ultimately vest:

Certain optionees experienced disqualifying dispositions of incentive stock options during the
year ended December 31, 2007 and 2008. Disqualifying dispositions result in a tax deduction in our corporate tax return equal to the intrinsic value of the option at exercise. To the extent we have previously recorded share-based compensation
expense related to disqualifying dispositions of incentive stock options, we record the benefit from the disqualifying dispositions as a reduction in our income tax provision.

As a result of disqualifying dispositions of incentive stock options during 2008 and 2007, tax benefits of $0.2 million and $2.1
million, respectively, related to options that were granted prior to the adoption of Compensation-Stock Compensation, Share-Based Compensation (Note 10), were recorded as a reduction of our 2008 and 2007 tax liability and an
increase to additional paid-in capital. The tax benefit related to the exercise of options granted subsequent to the adoption so share-based compensation was recorded as a reduction of current year tax expense and the tax liability. There was no
material disqualifying dispositions for 2009.

Restricted Stock Awards

During 2007, we began issuing restricted stock awards to certain directors, officers and employees under the First Amended and Restated Plan.
Compensation expense for such awards, based on the fair market value of the awards on the grant date, is recorded during the vesting period. Restricted stock awards generally vest 25% annually over a four-year service period.

A summary of restricted stock awards activity follows:

The total grant date fair value of shares vested under such grants during 2009, 2008 and
2007 was $1,809,000, $1,360,000 and $535,000, respectively.

Note 10.    Share-Based Compensation

Effective January 1, 2006, we adopted Compensation-Stock Compensation (ASC 718). Prior to the adoption of Compensation-Stock
Compensation, we used the minimum-value method afforded by the Compensation-Stock Compensation topic for disclosure purposes. Since all options granted prior to January 1, 2006 were granted at exercise prices that were equal to the
fair market value of the underlying stock on the date of the grant, no share-based compensation for stock options was recorded in the accompanying financial statements prior to 2006 and we are not required to record compensation expense for stock
options granted prior to January 1, 2006 unless the terms of those options are subsequently modified. Since adoption, we recognize share-based compensation expense for all share-based awards granted after January 1, 2006 using the
prospective transition method. Under that transition method, results for prior periods have not been restated.

With the
exception of one grant issued in December 2007 with market-based vesting conditions, discussed further below, the fair values of awards granted under the First Amended and Restated Plan were estimated at the date of grant using the Black-Scholes
option pricing model and the following weighted average assumptions:

|Volatility                             |  |                         | 60.9 | % |      |   | 51.8 | %    |  |   | 61.3 | %

Applying the
principles of the Compensation-Stock Compensation, the volatility of our common stock is estimated at the date of grant based on a weighted-average of the implied volatility of publicly traded 30-day to 270-day options on the common stock of
a select peer group of similar companies (Similar Companies), the historical volatility of the common stock of Similar Companies and, beginning in late 2007, the historical volatility of our common stock. The risk-free interest rate that
was used in the Black-Scholes option valuation model is based on the implied yield in effect at the time of each option grant, based on US Treasury zero-coupon issues with equivalent remaining terms. We use an expected dividend yield of zero in the
Black-Scholes option valuation model, as we have no intention of paying any cash dividends on our common stock in the foreseeable future. Compensation-Stock Compensationrequires us to estimate forfeitures at the time of grant and revise
those estimates in subsequent periods if actual forfeitures differ from those estimates. We use historical data to estimate pre-vesting option forfeitures and record share-based compensation expense only for those awards that are expected to vest.
We amortize share-based compensation on a straight-line basis over the requisite service period of the awards, which is generally the vesting period. The expected term (life) of all stock option awards has been calculated using the simplified
method as defined by Compensation-Stock Compensation because, due to the limited time our common stock has been publicly traded, we lack sufficient historical data to provide a reasonable basis to estimate the expected term of these
options.

In June 2007 and August 2008, under the terms of the separation agreements of two former executives, we accelerated
the vesting of certain options held by those executives permitting them to purchase previously unvested shares of our common stock within specified periods following their terminations. The terms of the August 2008 separation agreement also
accelerated the vesting of an award of approximately 2,000 shares of restricted stock. The modifications of these awards resulted in $280,000 and $192,000 of compensation expense in 2008 and 2007, respectively.

In December 2007, we granted our President and Chief Executive Officer an option to purchase
500,000 shares of our common stock at the price of $12.80 per share which vests, in 25% increments, only upon attainment of specified market-based conditions tied to the market value of our common stock. Under the provisions of Compensation-Stock
Compensation, the fair value of share-based grants with a market vesting condition must be modeled and valued with a path-dependent valuation technique. Accordingly, we estimate the value of such awards using the Monte Carlo binomial simulation
model. The primary assumptions used in the model are volatility, a risk-free interest rate, starting stock price, transferability restrictions and the terms of the award, as follows:



| |  |  | Risk-free interest rate of 3.98%;
| | - |  | ---------------------------------



| |  |  | Dividend yield of zero;
| | - |  | -----------------------



| |  |  | Expected option life of 10 years; and
| | - |  | -------------------------------------



| |  |  | Volatility of the expected market price of our common stock over that term of 53.9%.
| | - |  | ------------------------------------------------------------------------------------

Using these assumptions and inputs, we estimated that the weighted average grant date fair value of this award was $5.68 per option, with
derived service periods ranging from 15 to 32 months for the four performance levels, and averaging 24 months. The calculated $2.8 million fair value of this award must be recognized as expense over a weighted average period of approximately two
years whether the market conditions are met or not so long as the grantee meets the service condition.

The following table
summarizes the share-based compensation expense we recorded in accordance with the provisions of Compensation-Stock Compensation:

As of December 31, 2009, there was $15.0 million
of total unrecognized compensation cost related to non-vested share-based compensation that is expected to be recognized over a weighted-average period of 1.8 years. We expect to record approximately $5.0 million in share-based compensation in 2010
related to options and restricted stock awards outstanding at December 31, 2009.

Note 11.    Other Employee Benefit Plans

Defined Employee Contribution Plans

We have a 401(k) plan that allows all full-time eligible employees to contribute up to 15% of their annual compensation, subject to certain limitations. We match 50% of the first 6% for each employees contribution, and may, at our
discretion, make additional contributions regardless of profitability. In July 2009, the Company made the decision to temporarily suspend the Company matching contribution under the 401(k) plan. We recorded contribution related expense of $409,000,
$698,000 and $551,000 in the years 2009, 2008, and 2007, respectively.

Executive Retention and Severance Plan

In April 2005, the Board of Directors and stockholders approved the Executive Retention and Severance Plan (ERS), which was
subsequently amended and restated in December 2008, to promote the interests of our business and stockholders by attracting and retaining executive personnel and other key employees. The ERS is designed to provide certain executive personnel with
specified compensation and benefits in the event of a qualifying termination of employment in connection with a change in control of the Company, as defined in the ERS. At December 31, 2009 total potential severance obligations under the ERS
amounted to approximately $3.4 million, which is not recorded as a liability in the accompanying consolidated balance sheets.

Severance Policy

In October 2009, the Board of Directors approved a Severance Policy (Severance
Policy) to promote the interests of our business and stockholders by attracting and retaining executive personnel and employees. The Severance Policy is applicable to all full-time eligible employees who have completed at least six months of
service to the Company and, provides for certain compensation benefits in the event an employee is involuntarily terminated without cause.

Note 12.    Stockholders Equity

In August 2008, our Board of Directors authorized a
program to repurchase shares of our common stock having an aggregate value of up to $8.0 million. As of December 31, 2009, we had approximately $6.2 million remaining under this authorization. Acquisitions of shares may be made from
time-to-time at managements discretion, at prevailing prices in the open market, or in privately negotiated transactions, as permitted by securities laws and other legal requirements, and are subject to market conditions and other factors. The
program may be discontinued at any time. During 2009, we repurchased 422,701 shares under this program. Additionally, 52,823 shares that were withheld from employees for personal income tax purposes upon the vesting of restricted stock awards.
Collectively, these shares are recorded as treasury stock, at cost, in the Consolidated Balance Sheets.

Note
13.    Fair Value Measurements

We adopted Fair Value Measurements and Disclosures (ASC 820)
effective January 1, 2008 for financial assets and liabilities measured at fair value on a recurring basis. There was no impact upon the adoption to the consolidated financial statements. Under this standard, fair value is defined as the price
that would be received to sell an asset or paid to transfer a liability (i.e., the exit price) in an orderly transaction between market participants at the measurement date. Fair Value Measurements and Disclosures establishes a
hierarchy for inputs used in measuring fair value that minimizes the use of unobservable inputs by requiring the use of observable market data when available. Observable inputs are inputs that market participants would use in pricing the asset or
liability based on active market data. Unobservable inputs would be inputs that reflect the assumptions market participants would use in pricing the asset or liability based on the best information available

in the circumstances. The statement requires fair value measurements be classified and disclosed in one of the following three categories:

Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets and
liabilities.

Level 2: Quoted prices in markets that are not active or financial instruments for which all significant
inputs are observable, either directly or indirectly, and corroborated by market data.

Level 3: Prices or valuations that
require inputs that are both significant to the fair value measurement and unobservable.

The following table sets forth, by
level within the fair value hierarchy, financial assets (we have no financial liabilities) that are accounted for at fair value on a recurring basis as of December 31, 2009 and 2008 (in thousands):

Note 14.    Contingencies

Legal Matters

Note 15.    Subsequent Events

We have evaluated subsequent events of transactions that may occur for potential recognition and disclosure in our financial statements
through February 26, 2010, the date these consolidated financial statements were issued.

Note 16.    Segment
Information

We have adopted Segment Reporting (ASC 280) requiring segmentation based on our internal organization,
reporting of revenue and other performance measures. Operating segments are defined as components of an enterprise about which discrete financial information is available that is evaluated regularly by the chief operating decision maker, or decision
making group, in deciding how to allocate resources and in assessing performance. Our chief operating decision maker is our Chief Executive Officer. Our segments are designed to allocate resources internally and provide a framework to determine
management responsibility. We have four operating segments, as summarized below:



| |  |  | Products segmentincludes EnCase® Enterprise, EnCase® eDiscovery, EnCase® Forensic, Premium License Support Program, EnCase®
Portable, EnCase® Cybersecurity and hardware sales.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Professional services segmentis our division that performs consulting services and implementations. Consulting services include conducting
investigations using our software products.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Training segmentis our division that provides training classes in which we train our customers to effectively and efficiently use our software
products.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Maintenance segmentMaintenance related revenue and costs.
| | - |  | ----------------------------------------------------------

##### Table of Contents

We refer to the revenue generated by our professional services, training and maintenance
segments, collectively, as services revenue. Currently, we do not separately allocate operating expenses to these segments, nor do we allocate specific assets to these segments. Therefore, the segment information reported includes only revenues,
cost of revenues and gross profit. The following tables present the operations by each operating segment:
