Introduction

      We design, develop, manufacture and sell automated magnetic tape libraries used to store, retrieve and manage electronic data primarily in network computing environments. Tape libraries consist of cartridge tape drives, storage arrays of tape cartridges and robotics to move the tape cartridges from their storage locations to the tape drives under software control. Our tape libraries provide storage solutions for organizations requiring backup, recovery and archival storage of critical electronic information. Our tape libraries also can provide near-online storage as an alternative to disk drives. Our products are compatible with commonly used network operating systems, including UNIX, Windows NT, NetWare and Linux. Our tape libraries also are compatible with a wide range of storage management software packages, such as those supplied by Computer Associates, Legato, Tivioli and Veritas. We offer tape libraries for multiple tape drive technologies, including those using Advanced Intelligent Tape(AIT), Super Advanced Intelligent Tape(SAIT), Super Digital Linear Tape(SDLT), and Linear Tape Open(LTO) tape drives and media.

      We sell our tape libraries worldwide, primarily to value added resellers, system integrators, and original equipment manufacturers. These customers integrate our products with software from third party vendors to provide storage solutions, and in turn resell to end users. We custom configure each of our libraries based on each customer’s individual requirements, with a typical delivery time of one to three working days. This rapid fulfillment of customer orders allows our resellers to minimize their inventory levels and allows us to compete effectively with distribution channels used by our competitors.

      Qualstar was incorporated in California in 1984. The initial products were IBM compatible 9-track reel-to-reel tape drives. In 1995, we entered the tape automation market with a series of tape libraries incorporating 8mm tape drives. Since that time, we have introduced a succession of tape library models designed to work with 8mm and other tape drive technologies and tape media formats. Automated tape libraries and related products, such as tape drives and tape media, represented approximately 89.3% of revenues for fiscal 2001, approximately 82.9% of revenues for fiscal 2002, and approximately 79.8% of revenues for fiscal 2003. Sales of 9-track tape drives, services and other products accounted for the balance of our revenues.

      In July 2002, we purchased the assets of N2 Power, Incorporated, a supplier of ultra small high efficiency open-frame switching power supplies. Power supplies provided by N2 Power are utilized within our tape library products as well as sold to other original equipment manufacturers for incorporation into their products. N2Power products are sold under the N2Power brand name through outside sales representatives and distributors to original equipment manufacturers.

Industry Background

      Storing, managing and protecting data has become critical to the operation of many enterprises as the world economy becomes increasingly information dependent. The need for data storage is growing in response to the increase in the amount of data that is generated and must be preserved. The amount of data has been increasing due to the growth in the number of computers, the number, size and complexity of computer networks and software applications, and the emergence of new applications such as image processing, e-commerce, Internet services, medical, video and motion picture image storage, and other multi-media applications. In addition, businesses continue to generate increasing amounts of traditional business information with respect to their products, customers and financial information. This increase in the amount of data that is generated stimulates increases in the demand for data storage and the management of this data.

      The following factors are contributing to the growth in data storage:

	•	Increased demand from Internet and e-commerce businesses. The growth in the Internet and e-commerce has created businesses that depend on the creation, access and archival storage of data. We believe that the need to utilize databases will continue to grow as individuals and businesses increase their reliance on the Internet for communications, commerce and data retrieval.
	•	Growth in new types of data. The growth in data is being fueled not only by the increase in information but also in the types of stored data. For example, storage of graphics, audio and MP3, video, medical and security images, and multi-media uses such as video on demand, require far greater storage capacity than text and financial data.
	•	Growth in the critical importance of data. Corporate databases contain useful information about customer records, order patterns and other factors that can be analyzed and transformed into a valuable asset and a competitive advantage. The ability to efficiently store, manage and protect this information is important to the value and success of many businesses. The usefulness of past and present data is further enhanced by new sophisticated data mining software applications that can access and analyze large databases.
	•	Growth in network server computing applications and data. The use of server-based computer networks has shifted critical information and applications to network servers in order to allow more people to gain access to stored data as well as to create new data. As the speed of network computing has increased, numerous new applications have become feasible such as computer fax, e-mail and voicemail, all of which generate progressively more data. Organizations increasingly are aware of the need to protect this data as networks become a mission-critical element of many operations.
	•	Decrease in the costs of storing data. The costs of data storage have decreased with advances in technology and improved manufacturing processes. We expect these costs to continue to decrease. Decreases in costs not only encourage the storage of more data, but also make it more cost effective to add storage capacity rather than to remove old data, contributing to greater storage demand for data which in the past may have been purged periodically.

      The growth in data and need for storage is contributing to an evolution in traditional storage solutions. New open standard technologies are designed to provide high-speed connectivity for data-intensive applications across multiple operating systems, including UNIX, Windows NT, NetWare and Linux. These new methods of storage and data management technologies include the following:

	•	Fibre Channel. Fibre Channel is an interface technology based on industry standards for the connection of storage devices to networks. Interface is the term used to describe the electronics, cabling and software used to facilitate communications between devices. With Fibre Channel, users are better able to share stored information with other storage devices and servers over longer distances,

		with data transfer speeds significantly faster than the most common interface technology in use today, thereby increasing the importance of storage area networks.
	•	Storage Area Networks. Storage area network, or SAN, architecture applies the inherent benefits of a networked approach to data storage applications, which allows data to move efficiently and reliably between multiple storage devices and servers. The benefits of SAN architecture also include increasing the expandability of existing storage solutions and providing a higher level of connectivity than currently exists with traditional technologies. Additionally, SANs are able to provide these benefits across multiple operating systems.
	•	Advanced storage management software. The development of advanced storage management software has led to the use of tape as a lower-cost alternative to disk drives for on-line storage. This software automatically migrates infrequently accessed data to the lower cost storage medium such as a tape library. A user’s request for this data at some later date will recall the data automatically from the tape library and put it back on the disk file for user access. This sometimes is referred to as near-online storage. This process reduces the overall storage cost by using the least expensive storage medium to save data that is not expected to be needed on a frequent basis. Advances in storage management software have increased the ability of businesses to store, manage and retrieve important data, which in turn allows businesses to operate more efficiently.
	•	Network Attached Storage. Current storage devices are dependent on a file server for all commands and control. Network attached storage devices give storage devices file server functionality, which allow users to plug a storage library directly into a network without increasing demands on the file server or requiring a separate file server. This allows users to maintain, or even enhance, system performance while saving on both time and cost.

      Current non-volatile storage solutions are based primarily on three technologies: magnetic disk, optical disk and magnetic tape. Each of these solutions represents a compromise among a variety of competing factors including capacity, cost, speed, portability and data reliability. Magnetic tapes are removable, which allows them to be transported easily to an off-site location for security or protection from natural disasters. Magnetic and optical disks provide quicker access to stored data and generally are used when speed is important. Less frequently used data often is migrated from magnetic or optical disks to tape storage. Tape libraries provide a near-online solution, where less frequently used data files are stored on tapes instead of on disks.

      Automated tape libraries speed the tape loading process, eliminate errors induced by human operators, and enhance security compared to tapes that must be retrieved and loaded manually. Tape libraries also are capable of being operated from a remote location or during off-hours when no attendant is on duty. Automated tape libraries are a key component of a network administrator’s overall storage solution.

      Tape drives and tape media are two key components of tape libraries. The costs of tape drives and tape media have declined with advances in technology, and we expect this trend to continue. As prices decline, new applications for automated storage become justified, further increasing the number of applications that can benefit from the use of tape libraries. We believe that continued technological improvements in tape drives and tape media will further reduce overall storage costs in the future.

      Current and emerging applications for tape libraries include:

	•	Automated backup. Backup is the creation of a duplicate copy of current data for the purpose of recovery in the event the original data is lost or damaged. An automated tape library, in conjunction with storage management software, can backup network data at any time without human intervention. A library with multiple tape drives can backup data using all of its drives simultaneously, thus significantly speeding up the recording process. Backup tapes can be removed from the library and stored in an off-site location for protection against a physical or natural disaster at the primary site.

Table of Contents

	•	Archiving. Archiving is the storage of data for historical purposes. When important information is stored on tape, automated tape libraries, in conjunction with storage management software, can catalog tapes for future retrieval and prevent unauthorized removal or corruption of data by using password or key lock protection. Archival tapes provide a historic record for use in fraud detection, audit, legal and for other purposes. Tape libraries also are used for archiving because of the benefits offered by the tape medium, such as long-term data integrity, resistance to environmental contamination, ease of relocation, low cost, and the availability of “write once read many” or worm tapes and tape drives.
	•	Digital video. Digital recording of camera images for surveillance and security purposes is beginning to replace traditional analog VHS recording in mid-size to large installations such as airports, retail stores, government facilities and gaming operations. This is an important market opportunity because tape libraries eliminate the need for operators to load, unload, store and retrieve the vast number of tapes created in these facilities. Library based systems index, store and play back the video images on demand, thereby reducing the recall time and cost of operation significantly when compared to VHS recording and playback devices. Digital recording technology provides enhanced resolution and accommodates the recording of transactional data such as cash register transaction data and credit card data alongside the video image, which is not possible with VHS recording technology.
	•	Image management. Storage-intensive applications such as satellite mapping and medical image management systems are turning to tape libraries because of the cost advantage over traditional storage methods. X-ray images or MRI results, for instance, must frequently be kept on file for years. Tape library storage of a digitized image costs considerably less than storing a film copy, and can be recalled years later with considerably less effort. Additionally, there is a trend to require that these records be kept available for longer periods of time.

      The requirements for storage solutions vary depending on the size of an enterprise, the type of data generated and the amount of data to be stored. With the increased dependence on stored data, most organizations, regardless of their size, have a heightened need for storage solutions that integrate devices such as tape drives, tape libraries and storage management software. Those organizations with sufficient in-house information technology resources can rely on their internal infrastructure and expertise to design, purchase and implement their own storage solutions. These organizations may elect to purchase equipment from distributors or directly from original equipment manufacturers. Many organizations, however, do not have sufficient in-house resources but often have the same need for data storage solutions. These organizations often look to value added resellers to design, supply and install their storage solutions.

      Value added resellers develop and install storage solutions for enterprises that face complex storage needs but lack the in-house capability of designing and implementing the proper solution or have chosen to outsource these functions. Typically, the value added reseller will select among a variety of different hardware technologies and storage management software options, as well as provide installation and other services to deliver a complete storage solution for the end user.

      Value added resellers require rapid turnaround of orders, custom configuration of tape libraries, drop shipment to their customer’s site, compatibility with multiple tape formats and storage management software, and marketing and technical support.

      Original equipment manufacturers generally resell products made by others under their own brand name and typically assume responsibility for product sales, service and support. Original equipment manufacturers enable manufacturers, such as Qualstar, to reach end users not served by other reseller distribution channels and to serve select vertical markets where specific original equipment manufacturers have exceptional strength. Original equipment manufacturers require special services such as product configuration control, extensive qualification testing, custom colors and private labeling.

Our Solution

      We offer storage solutions that respond to the growing data management challenges facing businesses today, while addressing the unique needs of value added resellers and original equipment manufacturers.

      We believe that high product reliability is important to the end users of our products due to the critical nature of the data that is being stored, shorter time periods available for the back-up operations, and the operation of backup systems during hours when personnel may not be available to respond to problems. To address these concerns, we emphasize quality and reliability in the design, assembly and testing of our products which reduces the potential for product failures and results in products that require little maintenance.

      The technology utilized within automated tape libraries is continuously evolving due to advances in data recording methods, component cost reductions, advances in semiconductor and microprocessor technologies, and a general trend toward miniaturization in the electronics industry. This changing technology requires that we continuously develop and market new products in order to prevent our product lines from becoming obsolete. To give a few examples, this year we completed development of 5 new models in our RLS rack-mount series of tape libraries, of which, all 5 models were shipping as of the date of this report. Furthermore, we introduced 4 models of our new TLS 5000 Series Tape Library which incorporates SAIT tape technology. SAIT tapes have the highest density available on the market at 500 gigabytes per tape (native), making the TLS 5000 Series Tape Library the lowest cost per gigabyte tape library on the market.

      Our tape libraries are compatible with over fifty third-party storage management software packages, such as those supplied by Computer Associates, Legato, Tivoli and Veritas. Storage management software enables network administrators to allocate the use of storage technologies among user groups or tasks, to manage data from a central location, and to retrieve, transfer and backup data between multiple workstations. We believe that storage management software is a crucial component of any automated storage installation, and the lack of compatibility is a significant barrier to entry for new tape library competitors. To ensure compatibility, our engineers work closely with the application software vendors during product development cycles. We do not have contracts with any application software vendors, nor do we need access to their software code to design our products. We maintain relationships with them by supplying evaluation tape libraries so they can qualify their software to work with our tape libraries and by evaluating their software for compatibility with our tape libraries. We also support our relationships with them by keeping them informed as to current and contemplated changes to our products and by referring business to them when value added resellers or end users inquire about software sources.

      We have focused our business primarily on supporting value added resellers and original equipment manufacturers as the most effective and profitable distribution channels for our tape libraries. Our solution is to offer our resellers reliable tape libraries, multiple tape format choices, and more attractive profit opportunities than do other tape library manufacturers. We custom configure each of our libraries based on the resellers’ requirements, with a typical delivery time of one to three working days. Our solution for original equipment manufacturers is to offer them control over product design changes, qualification testing, and private labeling. We believe these factors enhance the resellers’ and original equipment manufacturers’ ability to sell our products and encourage them to remain loyal to Qualstar.

Strategy

      Our goals are to enhance our position as a supplier of automated tape libraries and to increase our market share in each of the tape formats in which we compete. To achieve these goals, we intend to:

	•	Offer libraries for multiple tape drive technologies. We offer tape libraries for a range of tape drive technologies, including Advanced Intelligent Tape (AIT), Super Advanced Intelligent Tape (SAIT), Super Digital Linear Tape (SDLT), and Linear Tape Open (LTO) tape media formats. By offering products based on multiple tape drive technologies, we reduce our dependence on the success of any single technology and can offer products that target the specific preferences of resellers and their end-user customers.

Table of Contents

	•	Focus distribution on value added reseller channels. We sell our products primarily through selected value added resellers who have a strong market presence, have demonstrated the ability to work directly with end users, and who maintain relationships with major vendors of storage management software. Because we market our products primarily through this channel, we have implemented a variety of programs to support and enhance our relationships with our reseller partners. These programs are designed to increase the likelihood of closing a sale and to increase the reseller’s profit margins. We intend to maintain our marketing presence in support of this distribution channel. We conduct business with our value added resellers on an individual purchase order basis and no long-term commitments are involved. Additionally, there are no exclusive territories assigned to our value added resellers.
	•	Maintain and strengthen original equipment manufacturer relationships. We sell our products to several companies under private label or original equipment manufacturer relationships. Original equipment manufacturer sales enable us to reach some end users not served by our value added resellers. The same product characteristics that make our tape libraries attractive to value added resellers also are important to original equipment manufacturers. We will continue to pursue and develop opportunities with original equipment manufacturers. We conduct business with our original equipment manufacturer customers on an individual purchase order basis and no long-term commitments are in place.
	•	Develop libraries for new tape technologies. The tape drive industry is continuously advancing the state of technology. We will continue to monitor new product releases and design new libraries for those technologies that appear promising and meet our standards for capacity, quality and reliability.
	•	Maintain our rate of innovation. We plan to maintain our high level of research and development efforts in order to exploit emerging technologies and product opportunities. We intend to continue the expansion of our product lines to incorporate higher capacities and new technologies.

      We believe that our experience, efficiency and strict control over the development and manufacturing of new products are key factors in the successful execution of our strategy. We design our tape libraries with a high percentage of common parts, use quality components and minimize the number of moving parts. We utilize proprietary techniques in the design, production and testing of our libraries in order to simplify the manufacturing process and reduce our costs. We produce all of our products at a single facility and control our inventory closely to provide rapid delivery to our customers. These steps allow us to design and bring to market new products rapidly in response to changing technology.

Products

     Tape Libraries

      We offer a number of tape library families, each capable of incorporating one or more tape drive technologies, as summarized in the following table:

(1)	A Terabyte is one million megabytes, or one thousand gigabytes. The table shows native capacity and excludes gains from data compression, which can increase capacity by more than 100%.

Table of Contents

      Some of our tape library product families include a number of models that differ in storage capacity, price and features. Our libraries are installed in network computing environments ranging from small departmental networks to enterprise-wide networks supporting hundreds of users. We believe that selling products for multiple tape drive technologies insulates us somewhat from the dynamics of the marketplace as various tape standards compete for market share. This helps our products appeal to the broadest possible range of end-user market segments. This wide range of products makes us a one-stop supplier for our value added reseller and original equipment manufacturer customers, enabling them to meet most end-user requirements for a specific tape format. Our wide range of products for competing tape drive technologies also helps to insulate us from the occasional supply shortages from tape drive or tape media manufacturers.

      Tape libraries generally contain two or more tape drives and from several to thousands of tapes. We concentrate our product offerings in the middle segment range of 12 to 600 tapes. We design our tape libraries for continuous, unattended operation. Multiple tape drives allow simultaneous access to different data files by different users on the network, and increase the rate at which data can move on to, out of, or within the network. A library with multiple tape drives can back up data using all drives simultaneously, significantly speeding up the recording process. Within the library, tape cartridges sometimes are stored in removable magazines, allowing for bulk removal of the tapes. Our libraries also offer key features such as barcode readers to scan cartridge labels, and an input/output port for importing and exporting individual tapes under system control. Many of our library models are expandable after installation by increasing the number of tape storage positions. This feature provides the end user with the ability to increase data capacity as storage needs grow.

      We offer automated tape libraries with different data storage capacities and data transfer rates. We continue to develop and release new libraries to expand our product offerings to meet the changing demands of the marketplace. In addition, we continue to develop enhancements and improvements for our existing products in order to maintain our competitive position in the marketplace.

      Our tape libraries incorporate a number of specialized features that we believe improve reliability, serviceability and performance, including:

	•	Rapid tape drive replacement. We design our libraries so that a tape drive can be replaced quickly without special tools. This feature minimizes the off-line time required when a tape drive must be replaced, and frequently avoids the high cost and delays of a service call.
	•	Fibre Channel connectivity. We offer a Fibre Channel option on most of our models to meet the needs of storage area networks and other high performance applications.
	•	Closed-loop servo control. Our tape libraries use digital closed-loop servo control for robotic motion to provide precise tape handling. This yields robotic motion that is smooth, repeatable and highly reliable.
	•	Brushless motors. We use only brushless electric motors in our tape libraries. Motors are a key component in any robotic system. Brushless motors provide longer life and less electrical noise compared to conventional brush-type motors. We build many of our own motors in order to obtain optimum performance and reliability.
	•	Variable I/ O Port. Our VIOP feature allows IT administrators the ability to select the number of cartridge slots that can be dedicated to bulk import or export of media to or from the library.
	•	Remote management. Many larger companies with global back-up solutions or disaster management programs require tape libraries that can be placed off-site in various regions but must be administered from a single location. With our Q-Link remote manager, our customers have the ability to put our products anywhere in the world and manage them from a single administrative hub using a standard web browser.

      Our TLS Series product line is specifically designed to be placed on the floor or on a table top, without the need for a special equipment rack. If requested, we provide our customers with an adapter kit for mounting some models in a rack. Other manufacturers design libraries primarily for rack-mounting, and supply an adapter for table-top use. We chose the opposite approach to distinguish ourselves from many of our

      During Fiscal 2003 we commenced shipments of our RLS Series of tape libraries. These products are designed to fit conveniently in equipment racks utilizing only five standard units, or a total of 8.75 inches of rack space. In addition, the RLS can provide all of the high-availability features needed in the most demanding applications such as dual-redundant power supplies and hot-swappable power supplies and tape drives. We believe these features give the RLS Series of tape libraries a competitive advantage over other compact rack-mount tape libraries that do not offer as robust a combination of features. We believe this product line will provide a cost effective solution for a large portion of our customer base.

     Other Products

      We have manufactured 9-track auto-loading reel-to-reel tape drives since 1990. Demand for 9-track tape drives has been declining for many years, and we expect overall demand for 9-track tape drives to continue to decline in the future. Therefore, we announced the end of the life for 9-track tape drives. In addition to our tape libraries and 9-track tape drives, we sell ancillary products such as tape media, tape magazines, cables, bar code labels and adapters for rack mounting our tape libraries.

      In July of 2002, we purchased the assets and intellectual property of N2Power, Incorporated, a privately held company located in Newbury Park, California. N2Power designs, develops, manufactures, and sells ultra small high-efficiency open-frame switching power supplies based upon its patented technology. Since the purchase, N2Power has been relocated to our facility in Simi Valley, California. N2Power products are utilized within our tape libraries as well as sold on the open market primarily through outside sales representatives and distributors to original equipment manufacturers.

Sales and Marketing

     Sales

      We sell our tape library products primarily through value added resellers. Our direct sales force usually will initiate contact with value added resellers who might be likely candidates to sell our tape libraries. We strive to develop relationships with resellers who have expertise in storage management applications, established relationships with end users and the experience to understand and satisfy their customers’ needs.

      We believe that by selling directly to value added resellers, we have an advantage over competitors who force resellers to purchase through distributors and who sometimes sell directly to end users, thereby competing with their own resellers. Some of the advantages of our strategy include the following:

	•	Higher profit margins. By avoiding the extra distribution markup, higher profit margins are available to be shared by both us and the reseller.
	•	Custom configurations. By circumventing the distribution step, we are able to offer custom configurations of our products, such as special paint, private branding and non-standard interface options, on very short notice.
	•	Channel conflicts avoided. We refer all end-user inquiries to our reseller partners. Because they know that we typically do not sell directly to the end user, there is an attitude of cooperation between the reseller and us. Frequently, our sales representatives make end-user visits with the reseller to help close a pending sale.
	•	Credit. We typically extend credit to resellers if they meet our credit requirements.
	•	Rapid delivery. We generally ship a product to the reseller within one to three working days of confirming an order, rivaling the delivery time of many distributors.

      Although we sell our tape libraries primarily to value added resellers, we believe that original equipment manufacturers are an important element of our business. We strive to work with original equipment manufacturers early in the product development cycle so that we can obtain valuable product development

      Our sales are spread across a broad customer base. For the year ended June 30, 2003, no single customer accounted for more than 10% of our revenue.

      Our international sales efforts are currently directed from our headquarters in Simi Valley, California. European sales are coordinated through our European sales office in the United Kingdom. We intend to continue to develop our international markets and create additional outlets for our products. All of our international sales are denominated in U.S. dollars. Revenues from customers outside of North America were $13.9 million, or 26.9% of revenues in fiscal 2001, $12.1 million or 32.2% of revenues in fiscal 2002, and $9.9 million or 29.4% of revenues in fiscal 2003.

      We support our sales efforts with a broad array of marketing programs designed to generate brand awareness, attract and retain qualified value added resellers and inform end users about the advantages of our products. We provide our resellers with a full range of marketing materials, including product specifications, sales literature, software connectivity information and product application notes. We train our resellers to sell our products and to answer customers’ questions. We advertise in key publications, and participate in trade shows. We display our products under the Qualstar brand name at various trade shows including the COMDEX Fall trade show, and participate in other trade shows in partnership with our principal suppliers and resellers. We support our marketing and customer support with a website that features comprehensive marketing and product information.

      Another element of our marketing plan is our lead registration program. This program awards value added resellers that uncover sales opportunities and promote our products to the end user. In exchange for this effort, the reseller is rewarded with a higher profit margin on that particular sale. The lead registration program gives our reseller partners an advantage over their competitors who purchase from distribution channels. We conduct sales and technical training classes for our resellers. We also conduct various promotional activities for resellers and end users, including product-specific rebates and co-operative advertising.

Customer Service and Support

      We believe that strong customer service and support is an essential aspect of our business. Our customer service and support efforts consist of the following components:

	•	Technical support. Our technical support personnel are available twenty four hours per day, Monday through Friday. Technical support personnel are available to all customers at no charge by telephone, facsimile and e-mail to answer questions and solve problems relating to our products. Our technical support personnel are trained in all aspects of our products. Our support staff is located at our headquarters in Simi Valley, California. We sell service contracts for on-site service of our tape libraries installed within the United States, which are fulfilled by IBM.
	•	Engineering. Our engineers provide both pre-and post-sales support to our resellers. Engineers typically become involved in more complex problem-solving situations involving interactions between our products, third-party software, network server hardware and the network operating systems. Engineers work with resellers and end users over the telephone and, in certain situations, visit the customer’s site.
	•	Training. We offer a product maintenance training program for end users, value added reseller and original equipment manufacturer maintenance personnel. We conduct our training classes at our headquarters, as well as on-site at the locations of our value added resellers or original equipment manufacturers.

	•	Warranty. The standard warranty period on our tape libraries is three years. During the first year for our TLS libraries and the first three years for our RLS libraries, we offer immediate replacement of defective products at no charge, subject to availability and credit approval of the purchaser. The purchaser is responsible for returning the defective product to us in a timely manner without damage. After the first year, the customer must first ship the tape library to our factory, where we will service the product during the warranty period at no charge. We offer out-of-warranty factory service at a flat fee plus applicable taxes, duties and transportation costs. For tape drives, we pass the warranty provided by the drive manufacturer on to our customer. On-site service for library products is available within the United States and some foreign countries for an extra charge. We contract with outside service providers to supply on-site service.

      We manufacture our products at our facility in Simi Valley, California. We currently operate four assembly lines during one daily eight-hour shift. As needs require, we have the ability to add a second or third shift to increase our capacity.

      In order to respond rapidly to sales orders, we build our tape libraries to a semi-finished state in advance of receipt of an order, perform full testing and then place the tape libraries in a holding area until an order is received. Once an order is confirmed, we remove the unit from the holding area, install tape drives and configure the unit to meet the specific requirements of the order, retest and then ship.

      The manufacturing cycle to bring the tape libraries to a semi-finished state is approximately five working days. We believe that this capability represents an effective way to control our inventory levels while maintaining the ability to fill specific customer orders in short lead times. We coordinate inventory planning and management with suppliers and customers to match our production to market demand. Once we confirm a product order, we generally ship the product to the customer within one to three working days. We believe this response time is among the fastest in the industry, and gives us a competitive edge. Because we fill the majority of our orders as they are received, our backlog generally is small and is not indicative of future sales.

      We select our suppliers carefully based on their ability to provide quality parts that meet our specifications and volume requirements. Inventory planning and management is coordinated closely with suppliers to match our production needs. Many of the components assembled into our libraries are standard off-the-shelf parts, which reduces the risk of part shortages and allows us to maintain inventory of these parts at a minimum. A number of our component parts are not available off the shelf, but are designed to our specifications for integration into our products.

      Tape drives and tape recording media are available only from a limited number of suppliers, some of which are sole-source providers. Some of our suppliers compete with us by selling their own tape libraries. The risk of allocation is greater upon the introduction of a new tape drive technology. Any disruption in supplies of tape drives or tape media could delay shipments of our products. We have experienced only one situation involving a limited supply of components. Between January 1999 and January 2000, Sony Electronics, Inc., our sole-source supplier of Advanced Intelligent Tape drives and tape media, was unable to provide us with sufficient quantities of 50 gigabyte tape media to meet our order volume. During this period, our customers generally did not delay purchases of Advanced Intelligent Tape libraries from us because of this shortage, but accepted delivery of tape libraries with a partial shipment of 50 gigabyte tape media or accepted 36 gigabyte tape media, which was available during that period.

      N2Power products are currently produced in China by a contract-manufacturing firm. We provide complete production documentation specifying each component and assembly techniques. We also specify performance criteria used to test the power supplies after they complete a burn-in cycle at elevated temperatures. Finished power supplies are shipped to our Simi Valley facility where they undergo further quality control inspections and tests prior to shipping to our OEM customers.

Competition

      The market for automated tape libraries is intensely competitive and characterized by rapidly changing technology and evolving standards. Because we offer a broad range of libraries for different tape drive technologies, we tend to have a large number of competitors that differ depending on the particular format and performance level. We compete in a segment of the overall tape library market that focuses on small to mid-range network computing environments. Our principal competitors in this market segment include StorageTek, Quantum/ATL Products, Advanced Digital Information Corporation (ADIC), Overland Storage, and Spectra Logic.

      Many of our competitors have substantially greater financial and other resources, better name recognition, larger research and development staffs, and more capabilities in manufacturing, marketing and distributing products than we do. Our competitors may develop new technologies and products that are more effective than our products. We are not ISO-9000 certified, which may limit some customers’ ability to purchase our products. However, we do not believe that our current determination not to seek ISO-9000 certification has affected our sales to date.

      As a greater number of competitors introduce products in a particular tape drive technology, the increased competition normally results in price erosion, a reduction in gross margins and a loss of market share for all competitors. We cannot assure you that we will be able to compete successfully against either current or potential competitors or that competition will not cause a reduction in our revenues or profit margins. We believe that our ability to compete depends on a number of factors, including the success and timing of new product developments by us and by our competitors, compatibility of our products with a broad range of computing systems, product performance, reliability, price, marketing and sales execution, and customer support. Specifically, we believe that the principal competitive factors in the selection of a tape library include:

	•	reliability of the robotic assembly that handles the tape cartridges;
	•	purchase price;
	•	storage capacity;
	•	speed of data transfer;
	•	compatibility with existing network operating systems and storage management software;
	•	after-sale expandability of a tape library to meet increasing storage requirements;
	•	expected product life and cost of maintenance; and
	•	the availability of optional features
	•	physical configuration and power requirements of the library.

      We believe our tape libraries compete favorably with respect to these factors.

Research and Development

      Our research and development group of 29 people consists of two teams. Our original team located in Simi Valley, California, has developed over 40 separate tape library models for eleven different tape formats over the last eight years. In fiscal 2002 we established our Advanced Development Group in Boulder, Colorado. They are responsible for the design and development of a new generation of tape libraries. Our engineers are a diverse and robust group who have the capability to meet the needs of a complex and demanding data storage market.

      Our research and development efforts rely on the integration of multiple engineering disciplines to generate products that meet market needs in a competitive and timely fashion. Successful development of automated tape libraries requires the integration of mechanical design, electronic design packaging, software design, and firmware design into a single product. Product success also relies on the engineering group’s

Table of Contents

      We frequently develop new products in response to the availability of new tape drive technology. As tape drive manufacturers compete in the marketplace, they continually invest in research and development to gain performance leadership either by offering increasingly enhanced versions of their current tape drive products or by introducing an entirely new tape drive technology. We benefit from these industry developments by utilizing the new technology in our products. Our engineers work closely with various tape drive manufacturers through the drive development cycle to assure that reliable tape library and tape drive combinations are brought to market.

      The design architecture of our tape libraries makes use of common parts across most product families giving us the ability to develop and introduce new products quickly. If a new tape drive is an advanced version of one already incorporated in one or more of our products, our time and dollar investment to incorporate the new drive can be relatively small, with the primary focus being on verification testing. When the form factors differ, the time and investment requirements can grow substantially, and may require development of a new product family altogether.

      We also develop new products as we identify emerging market needs. Our sales and marketing, product development and engineering groups identify products to fulfill customer and marketplace needs. Our research and development group concentrates on leveraging previous engineering investments into new products. For example, our firmware is based on successive generations of the operating system developed for our first library. We also use common parts in our different library series, and leverage our electro-mechanical and electronic hardware technology from previous products into next generation designs. In some cases, entire subassemblies are transferable, leveraging not only engineering time but also materials purchasing, inventory stocking and manufacturing efforts.

      Our research and development expenses were $1.3 million in fiscal 2001, $2.1 million in fiscal 2002, and $4.0 million the year ended June 30, 2003. We anticipate spending at our current level, or slightly higher, on research and development in the future.

Intellectual Property

      We rely on copyright protection of our firmware, as well as patent protection for some of our designs and products. We also rely on a combination of trademark, trade secret and other intellectual property laws to protect our proprietary rights. However, we do not believe our intellectual property provides significant protection from competition. We believe that, because of the rapid pace of technological change in the tape storage industry, patent, copyright, trademark and trade secret protection are less significant than factors such as the knowledge, ability and experience of our personnel, and timely new product introductions.

      We enter into Inventions and Confidentiality agreements with our development engineers to protect our technology and designs. However, we do not believe that such protection can preclude competitors from developing substantially equivalent products.

Employees

      As of September 21, 2003, we had 111 full-time employees, including 35 in manufacturing, 29 in research and development, 6 in customer service, 18 in sales and marketing, and 23 in finance and administration. We also employ a small number of temporary employees and consultants as needed. We are not a party to any collective bargaining agreement or other similar agreement. We believe that we have a good relationship with our employees.

RISK FACTORS

Our principal competitors devote greater financial and marketing resources to developing and selling automated tape libraries. Consequently, we may be unable to maintain or increase our market share.

      We face significant competition in developing and selling automated tape libraries. Rapid and ongoing changes in technology and product standards could quickly render our products less competitive, or even obsolete. We have significantly fewer financial, technical, manufacturing, marketing and other resources than many of our competitors and these limited resources may harm our business in many ways. For example, in recent years several of our competitors have:

	•	acquired other tape library companies;
	•	increased the geographic scope of their market;
	•	offered a wider range of tape library products; and
	•	acquired proprietary software products that operate in conjunction with their products and the products of their competitors.

      In the future, our competitors may leverage their greater resources to:

	•	develop, manufacture and market products that are less expensive or technologically superior to our products;
	•	attend more trade shows and spend more on advertising and marketing;
	•	reach a wider array of potential customers through a broader range of distribution channels;
	•	respond more quickly to new or changing technologies, customer requirements and standards; or
	•	reduce prices in order to preserve or gain market share.

      We believe competitive pressures are likely to continue. We cannot guarantee that our resources will be sufficient to address this competition or that we will manage costs and adopt strategies capable of effectively utilizing our resources. If we are unable to respond to competitive pressures successfully, our prices and profit margins may fall and our market share may decrease.

We have a limited number of executives. The loss of any single executive or the failure to hire and integrate capable new executives could harm our business.

      The success of our business is tied closely to the managerial, engineering and business acumen of our existing executives. William J. Gervais, our President, has been largely responsible for the development of many of our tape libraries, has overseen our operations and growth, and established and maintained our strategic relationships. We expect that he will continue these efforts for the foreseeable future. Our future success will also depend on our ability to attract, retain and motivate key executives and other key personnel, many of whom have been instrumental in developing new technologies and strategic plans. However, our current dependence on a limited number of executives, for whom replacements may be difficult to find, entails a risk that we may not be able to supervise and manage our ongoing operations.

Our suppliers could reduce shipments of tape drives and tape media. If this occurs, we would be forced to curtail production, our revenues could fall and our market share could decline.

      Automated tape libraries and related products, such as tape drives and tape media, represented approximately 89.3% of our revenues for fiscal year 2001, approximately 82.9% of our revenues for fiscal 2002, and approximately 79.8% of our revenues for the year ended June 30, 2003. We depend on a limited number of third-party manufacturers to supply us with the tape drives and tape media that we incorporate into our automated tape libraries. Some tape drive manufacturers, including Sony Corporation and Quantum Corporation, compete with us by also manufacturing tape libraries. There can be no assurance that other tape drive manufacturers will not also begin to manufacture libraries.

Table of Contents

      Historically, some of these suppliers have been unable to meet demand for their products and have allocated their limited supply among customers. If suppliers limit our supply of tape drives or tape media, we may be forced to delay or cancel shipments of our tape libraries. The major supplier risks we face include the following:

	•	Sony Electronics, Inc. is our sole-source supplier of 8 millimeter Advanced Intelligent Tape drives and media, and Super Advanced Intelligent tape drives and media. Sony has allocated some of their products in the past and may allocate them again in the future. In fiscal 2001, we derived $39.8 million, or 77.1%, of our revenues, in fiscal 2002 we derived $24.6 million, or 65.3% of revenues, and in fiscal 2003, we derived $18.9 million, or 56.2% of our revenues from the sale of libraries, tape drives and tape media based on Sony Advanced Intelligent Tape technology. If Sony reduces its sales to us or raises its prices, we could lose revenues and our margins could decline.
	•	Quantum Corporation is our sole-source supplier of SDLT tape drives and competes with us as a manufacturer of automated tape libraries. In the past, Quantum has allocated quantities of tape drives among its customers. It is possible that Quantum will allocate again, and as a result, may be unable to meet our future SDLT tape drive requirements.
	•	The Linear Tape Open standard was developed by an industry consortium consisting of IBM, Hewlett Packard and Seagate. LTO competes with 8mm and other half-inch tape drives and media. IBM and Hewlett Packard both sell automated tape libraries that utilize LTO tape drives and compete with our products. Therefore, even if we receive adequate allocation, it may be at a price that renders our products uncompetitive.

      Our other suppliers have in the past been, and may in the future be, unable to meet our demand, including our needs for timely delivery, adequate quantity and high quality. We do not have long-term supply contracts with any of our significant suppliers. The partial or complete loss of any of our suppliers could result in lost revenue, added costs and production delays or could otherwise harm our business and customer relationships.

Our revenues could decline if we fail to execute our distribution strategy successfully.

      We distribute and sell our automated tape libraries through value added resellers and original equipment manufacturers, and intend to continue this strategy for the foreseeable future. Value added resellers integrate our tape libraries with products of other manufacturers and sell the combined products to their own customers. Original equipment manufacturers combine our tape libraries with their own products and sell the combined product under their own brand. We currently devote, and intend to continue to devote, significant resources to develop these relationships. A failure to initiate, manage and expand our relationships with value added resellers or original equipment manufacturers could limit our ability to grow or sustain our current level of revenues.

      Our focus on the distribution of our products through value added resellers poses the following risks:

	•	we may reach fewer customers because we depend on value added resellers to market to end users and these value added resellers may fail to market effectively or fail to devote sufficient or effective sales, marketing and technical support to the sales of our products;
	•	we may lose sales because many of our value added resellers sell products that compete with our products. These value added resellers may reduce their marketing efforts for our products in favor of products manufactured by our competitors;
	•	our costs may increase as value added resellers generally require a higher level of customer support than do original equipment manufacturers; and
	•	as the market for tape libraries matures, we expect that tape libraries designed for small and medium size businesses will not require the level of sales, marketing and technical support traditionally provided by value added resellers and, consequently, tape libraries for these customers will be increasingly sold through distribution channels rather than through value added resellers.

Table of Contents

      We depend upon our original equipment manufacturer customers’ ability to develop new products, applications and product enhancements that incorporate our products in a timely, cost-effective and customer-friendly manner. We cannot guarantee that our original equipment manufacturer customers will meet these challenges effectively. Original equipment manufacturers typically conduct substantial and lengthy evaluation programs before certifying a new product for inclusion in their product line. We may be required to devote significant financial and human resources to these evaluation programs with no assurance that our products will ever be selected. In addition, even if selected by the original equipment manufacturer, there generally is no requirement that the original equipment manufacturer purchase any particular amount of product or that it refrain from purchasing competing products.

      We do not have any exclusive or long-term agreements with our value added resellers or original equipment manufacturers, who purchase our products on an individual purchase order basis. If we lose important value added resellers or original equipment manufacturer customers, if they reduce their focus on our products or if we are unable to obtain additional value added reseller or original equipment manufacturer customers, our business could suffer.

We rely on tape technology for all of our revenues. Our business will be harmed if demand for storage solutions using tape technology declines or fails to develop as we expect.

      We derive substantially all of our revenues from products that incorporate some form of tape technology. We expect to derive substantially all of our revenues from these products for the foreseeable future. As a result, we will continue to be subject to the risk of a decrease in revenues if demand for these products declines or if rising prices make it more difficult to obtain them. If storage products incorporating technologies other than tape gain comparable or superior market acceptance, our business could be harmed.

We depend upon the AIT tape format supplied by Sony Electronics Inc. for a large portion of our revenues. Should Sony abandon or fail to advance this tape format, future revenues or operating results could suffer.

      Sony Electronics Inc. is our sole supplier of AIT tape drives and tape media. If Sony should discontinue manufacturing AIT tape products or fail to advance AIT technology to keep pace with the industry trend of increasing tape capacity, our revenues or operating results could be significantly impacted.

Our revenues and operating results may fluctuate unexpectedly from quarter to quarter, which may cause our stock price to decline.

      Our quarterly revenues and operating results have fluctuated in the past, and may fluctuate in the future due to several factors, including:

	•	reductions in the size, delays in the timing, or cancellation of significant customer orders;
	•	fluctuations in product mix;
	•	the timing of the introduction or enhancement of products by us, our original equipment manufacturer customers or our competitors;
	•	expansions or reductions in our relationships with value added reseller and original equipment manufacturer customers;
	•	financial difficulties affecting our value added reseller or original equipment manufacturer customers that render them unable to pay amounts owed to us;
	•	the rate of growth in the data storage market and the various segments within it;
	•	timing and levels of our operating expenses; and
	•	availability of tape media.

      We believe that period to period comparisons of our operating results may not necessarily be reliable indicators of our future performance. It is likely that in some future period our operating results will not meet your expectations or those of public market analysts.

      Any unanticipated change in revenues or operating results is likely to cause our stock price to fluctuate since such changes reflect new information available to investors and analysts. New information may cause investors and analysts to revalue our stock and this, in the aggregate, may cause fluctuations in our stock price.

Our lack of significant order backlog makes it difficult to forecast future revenues and operating results.

      We normally ship products within a few days after orders are received. Consequently, we do not have significant order backlog and a large portion of our revenues in each quarter results from orders placed during that quarter. Because backlog can be an important indicator of future revenues, our lack of backlog makes it more difficult to forecast our future revenues. Since our operating expenses are relatively fixed in the short term, unexpected fluctuations in revenues could negatively impact our quarterly operating results.

If we fail to develop and introduce new tape libraries on a timely and cost-effective basis, or if our products do not contain the features required by the marketplace, we will eventually lose market share and sales to more innovative competitors.

      The market for our products is characterized by rapidly changing technology and evolving industry standards. The future success of Qualstar will depend on our ability to anticipate changes in technology, to develop new and enhanced products on a timely and cost-effective basis, and to introduce, manufacture and achieve market acceptance of these new and enhanced products. Our products are facing increasing competition from automated tape library products and likely will face competition from other types of storage devices that may be developed in the future.

      Development schedules for high technology products are inherently subject to uncertainty and there can be no assurance we will be able to meet our product development schedules or that our development costs will be within budgeted amounts. If the products or product enhancements developed are not deliverable due to technical problems, quality issues or component shortages, or if such products or product enhancements are not accepted by the marketplace or are unreliable, then our business, financial condition and results of operations may be materially adversely affected.

      The introduction of new storage technologies or the adoption of an industry standard different than our current product standards could render our existing products obsolete.

We depend upon independent software vendors to provide software that integrates our libraries with computer operating systems.

      The utility of an automated tape library depends partly upon the storage management software, which supports the library and integrates it into the user’s computing environment to provide a complete storage solution. We do not develop and have no control over the development of this storage management software. Instead we rely on independent third party software vendors to develop and support this software. Accordingly, the continued development and future growth of the market for our products will depend partly upon the success of software vendors to meet the overall data storage and management needs of tape library purchasers and our ability to maintain relationships with these firms. Although we do not have contracts with any independent software vendors, we maintain relationships with them by:

	•	supplying evaluation tape libraries so they can qualify their software to work with our tape libraries;
	•	evaluating their software for compatibility with our tape libraries;

16

Table of Contents

	•	keeping them informed as to current and contemplated changes to our products; and
	•	referring business to them when value added resellers or end users inquire about software sources.

Our customers have the right to return our products in certain circumstances. An excessive number of returns may reduce our revenues.

      Our customers have 30 days from the date of purchase to return products that do not conform with the end-user’s specifications. We may otherwise allow product returns if we think that doing so maximizes the effectiveness of our sales channels and promotes our reputation for quality and service.

      Although we estimate and reserve for potential returns in our reported financial results, actual returns could exceed our estimates. If the number of returns exceeds our estimates, our financial results could be harmed for the periods during which returns are made.

We may spend money pursuing sales that do not occur when anticipated or at all.

      Original equipment manufacturer customers typically conduct significant evaluation, testing, implementation and acceptance procedures before they begin to market and sell new models of tape libraries. This evaluation process is lengthy and may range from six months to one year or more. This process is complex and may require significant sales, marketing, engineering and management resources on our part. The process becomes more complex as we simultaneously qualify our products with multiple customers or pursue large orders with a single customer. As a result, we may expend resources to develop customer relationships before we recognize any revenue from these relationships, if at all.

We sell a significant portion of our products to customers located outside of North America. Currency fluctuations and increased costs associated with international sales could make our products unaffordable in foreign markets, which would reduce our revenue or profitability.

      Revenues from shipments to customers outside North America accounted for approximately 26.9% in fiscal 2001, 32.2% in fiscal 2002, and 29.4% in fiscal 2003. We believe that international sales will continue to represent a significant portion of our revenues. Our foreign sales subject us to a number of risks, including:

	•	political and economic instability may reduce demand for our products or our ability to market our products in foreign countries;
	•	although we denominate our international sales in U.S. dollars, currency fluctuations could make our products unaffordable to foreign purchasers or more expensive compared to those of foreign manufacturers;
	•	restrictions on the export or import of technology may reduce or eliminate our ability to sell in certain markets;
	•	greater difficulty of administering business overseas may increase the costs of foreign sales and support;
	•	foreign governments may impose tariffs, quotas and taxes on our products;
	•	longer payment cycles typically associated with international sales and potential difficulties in collecting accounts receivable may reduce the profitability of foreign sales; and
	•	our current determination not to seek ISO-9000 certification, a widely accepted method of establishing and certifying the quality of a manufacturer’s products, may reduce sales.

      These risks may increase our costs of doing business internationally and reduce our sales or profitability.

We may have to expend significant amounts of time and money defending or settling product liability claims arising from failures of our tape libraries.

      Because our tape library customers use our products to store and backup their important data, we face potential liability if our products fail to perform. Although we maintain general liability insurance, our

A failure to develop and maintain proprietary technology may negatively affect our business.

      We rely on copyright protection of our firmware, as well as patent protection for some of our designs and products. We also rely on a combination of trademark, trade secret, and other intellectual property laws and various contract rights to protect our proprietary rights. However, we do not believe our intellectual property rights provide significant protection from competition. As a consequence, these rights may not preclude competitors from developing products that are substantially equivalent or superior to our products. In addition, many aspects of our products are not subject to intellectual property protection and therefore can be reproduced by our competitors.

Intellectual property infringement claims brought against us could be time consuming and expensive to defend.

      In recent years, there has been an increasing amount of litigation in the United States involving patents and other intellectual property rights. We currently are defending a lawsuit brought against us by Raytheon Company (“Raytheon”), which alleges that some of our tape library products infringe a patent owned by Raytheon. This lawsuit is described in Item 3 of this report. In the future, we may become subject to other claims or inquiries regarding our alleged unauthorized use of a third party’s intellectual property. An adverse outcome in litigation could force us to do one or more of the following:

	•	stop selling, incorporating or using our products or services that use the challenged intellectual property;
	•	subject us to significant liabilities to third parties;
	•	obtain from the owners of the infringed intellectual property right a license to sell or use the relevant technology, which license may not be available on reasonable terms, or at all; or
	•	redesign those products or services that use the infringed technology, which redesign may be either economically or technologically infeasible.

      Whether or not an intellectual property litigation claim is valid, the cost of responding to it, in terms of legal fees and expenses and the diversion of management resources, could harm our business.

Undetected software or hardware flaws could increase our costs, reduce our revenues and divert our resources from our core business needs.

      Our tape libraries are complex. Despite our efforts to revise and update our manufacturing and test processes to address engineering and componen
