Overview

We provide storage solutions that reliably move, manage and protect critical data and digital content. We deliver software and hardware components that provide
reliable storage connectivity and advanced data protection to leading OEM and distribution channel partners. Our software and hardware products range from ASICs, HBAs, RAID controllers, host RAID
software, Adaptec RAID Code (ARC) software, Advanced Data Protection software, Storage Management software, Snapshot software, ROC and other solutions that span the SCSI, Serial Attached SCSI, SATA
and iSCSI interface technologies. System integrators and white box suppliers build server and storage solutions based on Adaptec technology in order to deliver products with superior price and
performance, data protection and interoperability.

Our
broad range of RAID controllers, ASIC's and add-in cards give businesses a variety of price and performance options for connecting their storage. These options range from
low cost HBAs to high performance and high availability RAID controller cards. Further, our products use a common management interface designed to simplify storage administration and reduce related
costs. Our products are sold to enterprises, small and midsize businesses, government agencies and retail users engaged in a broad range of vertical markets across geographically diverse markets
through OEMs and distribution channel customers, including system integrators.

Our
new management team is continuing to perform a thorough analysis of our operations, which it initiated in the first quarter of fiscal 2006, and has begun implementing a detailed plan
to support our corporate strategy. This analysis of our operations includes a review of all aspects of our business,

Business Segment and Products Overview

In fiscal 2006, our DPS segment accounted for $276.2 million of our net revenues and our DSG segment accounted for $33.9 million of our net revenues
(See Note 16 of the Notes to Consolidated Financial Statements for further discussion of our segments' results).

Following
are discussions of our key product offerings for our DPS and DSG businesses.

DPS

Components.

RAID Controllers and HBAs.In fiscal 2006, we enhanced our line of RAID controllers with the introduction of two Serial ATA
II solutions for the PCI-X interface and three Serial Attached SCSI solutions, for both PCI-X and PCIe. Serial ATA II (SATA II), the successor to SATA technology for data
storage, is a point-to-point connection that delivers full throughput to each storage device by allowing multiple ports to be managed by a single controller. Adaptec SATA II
technology delivers data transfer rates with 3 Gb/s while also supporting 1.5 Gb/s (SATA I). Serial Attached SCSI is the enterprise storage interface that takes parallel SCSI into new dimensions of
performance, flexibility and scalability. With Serial Attached SCSI, customers enjoy performance many times faster than parallel SCSI and can mix and match Serial Attached SCSI and SATA drives for
cost and performance optimization.

Host I/O.Driven by market needs for capacity and data protection, the host I/O interfaces support various connectivity
requirements between the central processor to internal and external peripherals, including external storage devices. Adaptec host I/O products, which incorporate our proprietary ASIC technologies,
provide customers with high-speed PCI, PCI-X, PCIe, SCSI, Serial Attached SCSI or SATA technology. These technologies can be applied to a variety of applications, including
storage of email, medical records, digital images, and financial transactions. We have provided next-generation Serial Attached SCSI products to OEMs for testing and development.

iSCSI/TCP/IP Offload Engine.iSCSI is specifically designed to enable cost-effective SANs to be deployed to a
broad market, using existing Ethernet infrastructure and protocols, and provide lower total cost of ownership by retaining the existing networking, interoperability, manageability, and compatibility
advantages of Ethernet. With this technology, our customers will be able to use inexpensive, readily available Ethernet switches, hubs and cables to implement iSCSI-based SANs. We ship iSCSI HBAs
through distribution channel customers. Our networking focus has been on the development of products that will provide iSCSI and TOE functionality. We have invested over five years of research and
development efforts in iSCSI products. As a result of the strategic alliance that we entered into with ServerEngines in March 2005, we believe we have accelerated our ability to deliver
next-generation iSCSI products that can provide higher performance (10Gb/s).

Software

Our products incorporate software that simplifies data management and protection for businesses of all sizes. We distribute the software through various methods.
Some of our software is licensed independent of the hardware to run on a range of products, including ours.

A
discussion of the software we license is as follows:

Host RAID.Host RAID technology allows our customers to leverage the I/O components already incorporated on their servers to
connect them with RAID-provided low cost data protection. To date, such

6

---



functionality
has been considered important for mission critical data only. Host RAID enables customers not only to protect their data drives but also to include protection for the boot drives.

The
following software products are available in combination with hardware or can be purchased as an upgrade.

RAID.Our RAID technology reduces a customer's dependence on the reliability of a single disk drive by duplicating data
across multiple drives. We apply our RAID technology independent of disk drive interface to provide data protection on SCSI, ATA and SATA disk drives. This independence enables our RAID software,
firmware and hardware to be available across the full spectrum of servers from entry to enterprise. Our new RAID 6 solution can sustain two simultaneous drive failures in an array without downtime or
data loss. In fiscal 2005, Adaptec became the first vendor to ship a Serial
Attached SCSI RAID 6 solution. IBM has standardized on Adaptec RAID 6 software as well as our Zero Channel Serial Attached SCSI RAID controller for IBM's x366 xSeries servers. In fiscal 2006, we made
this RAID technology available to the channel by incorporating it into our new SATA and Serial Attached SCSI RAID controllers, as well as our current ROC-based U320 SCSI RAID controllers.
Along with the Dual Drive Failure Protection (RAID 6, 60), the Advanced Data Protection Suite also includes Striped Mirror (RAID 1E) that extends RAID 1 data availability across an odd number of
drives, Hot Space (RAID 5EE) that enhances RAID 5 performance by utilizing an extra drive, and Cobyback Hot Spare that automatically reconfigures a system when a failed drive is replaced. Snapshot
Backup, which allows users to create point-in-time copies of data, is an optional feature that customers may purchase to help streamline disaster recovery operations.

Storage-Virtualization.Our storage-virtualization software enables organizations to simplify management of multiple
homogenous external storage systems.

Adaptec Storage Manager.Adaptec Storage Manager is a single RAID storage management utility that enables customers and IT
managers to easily manage storage across DAS and SAN environments. It allows the user to configure, expand, manage and monitor local and remote RAID storage from a single client workstation.

DSG

Our DSG segment develops, manufactures and markets high-performance I/O connectivity, digital media products and flexible desktop storage and gaming
products for users and professionals in the desktop PC and notebook aftermarket. Our connectivity products enable connections between computers, peripherals and consumer electronic devices. Our
digital media products, including video and Media Center products, enable users to capture, create, manage and share television, digital audio and video on their computers, CDs and DVDs.

Sales, Marketing and Customers

We supply a broad range of storage products and maintain a sales, distribution, service and support infrastructure.

We
sell our products through our sales force to OEMs worldwide, who market our products under their brands. We work closely with our OEM customers to design and integrate current and
next generation products to meet the specific requirements of end users. The OEM sales force focuses on developing relationships with OEM customers. The sales process involved in gaining major design
wins
can be complex, lengthy, and expensive. Sales to these OEM customers accounted for approximately 62% of our total revenues in fiscal 2006.

We
also sell through our sales force to distribution customers worldwide, who market our products under the Adaptec brand; they, in turn, sell to VARs, systems integrators and retail
customers. We also sell

7

---



directly
to direct marketers, VARs and retailers who market our products under the Adaptec brand. We provide training and support for our distribution customers and to VARs. We also sell board-based
products and provide technical support to end users worldwide through major computer-product retailers. Sales to distribution customers accounted for approximately 38% of our total revenues in fiscal
2006.

We
emphasize customer service as a key element of our marketing strategy and maintain technical applications groups at our corporate headquarters and in the field. This includes
assisting current and prospective customers in the use of our products, and providing the systems-level expertise and software experience of our engineering staff to customers with particularly
difficult design problems. A high level of customer service is also maintained through technical support hotlines, email and dial-in-fax capabilities.

Our
primary OEM customers in fiscal 2006, in alphabetical order, included Dell, Fujitsu-Siemens, Hewlett-Packard and IBM. Our primary distributors in fiscal 2006, in alphabetical order,
included CPI Computer Partner Handels GmbH, Ingram Micro, Synnex, and Tech Data. Our primary retail customers in the DSG segment in fiscal 2006, in alphabetical order, included Best Buy, Circuit City
and CompUSA.

In
fiscal 2006, IBM and Dell accounted for 30% and 16% of our revenues, respectively. In fiscal 2005, IBM and Dell accounted for 24% and 15% of our revenues, respectively. In fiscal
2004, IBM and Dell accounted for 21% and 12% of our revenues, respectively.

We
have entered into several arrangements with IBM over the past several years. In May 2000, we entered into a patent cross-license agreement with IBM, which was subsequently
amended in March 2002, and obtained a release of past infringement claims made prior to January 1, 2000 and received the right to use certain IBM patents from January 1, 2000
through June 30, 2007. Additionally, we granted IBM a license to use all of our patents for the same period. In March 2002, we entered into a non-exclusive, perpetual
technology licensing agreement and an exclusive three-year product supply agreement with IBM. The technology licensing agreement grants us the right to use IBM's ServeRAID technology for
our internal and external RAID products. Under the product supply agreement, we deliver RAID software, firmware and hardware to IBM for use in IBM's xSeries servers. In June 2004, we completed
an acquisition and licensing agreement with
IBM for RAID intellectual property and the delivery of Adaptec RAID controllers for IBM's eServer iSeries and pSeries servers, or IBM i/p Series. In December 2004, we expanded the i/p Series
relationship with IBM to deliver Adaptec-branded RAID controllers and connectivity products, which were previously branded as IBM, for IBM's i/p Series directly through IBM's sales channel. In
September 2005, we sold the IBM i/p Series RAID business back to IBM. In addition, IBM purchased certain related inventory. We also granted IBM a nonexclusive license to certain intellectual
property and sold to IBM substantially all of the assets dedicated to the engineering and manufacturing of RAID controllers and connectivity products for the IBM i/p Series RAID business. For further
discussion on agreements between us and IBM, please refer to Notes 2 and 14 to the Notes to Consolidated Financial Statements.

International

We maintain operations in seven foreign countries and sell our products in additional countries through various representatives and distributors. We believe this
geographic diversity allows us to draw on business and technical expertise from an international workforce, provides both stability to our operations and diversifies revenue streams to offset
geographic economic trends and offers us an opportunity to penetrate new markets.

A
summary of our net revenue and net property, plant and equipment by geographic area is set forth in Note 16 in the Notes to Consolidated Financial Statements. We generated
approximately 72% of our overall revenues in 2006 from outside of the United States. These sales include sales to foreign subsidiaries of U.S. companies. A majority of our revenues originating outside
the United States was from commercial customers rather than foreign governments.

Competition

The markets for all of our products within the DPS and DSG segments are highly competitive and are characterized by rapid technological advances, frequent new
product introductions, evolving industry and customer standards and competitive pricing pressures. Our competitive strategy is to continue to leverage our technical expertise and concentrate on
delivering a comprehensive set of highly reliable, high performance storage and connectivity products with superior data protection that simplify storage management for organizations of all sizes. We
design advanced features into our products, with a particular emphasis on data transfer rates, software-defined features and compatibility with major operating systems and most peripherals.

We
believe the principal competitive factors in the markets for our DPS products are: product price versus performance, product features and functionality, reliability, technical service
and support, scalability and interoperability and brand awareness. We compete primarily with product offerings from Applied Micro Circuits Corporation (3Ware), Broadcom, LSI Logic and Promise.

We
believe the principal competitive factors in the markets for our DSG products are: product price/performance, brand awareness and distribution breadth, reliability, and technical
service and support. In the DSG segment, our SCSI products compete primarily against products using technology alternatives such as USB and FireWire/1394, which are available from companies such as
Belkin and SIIG, and our digital media products compete with product offerings of Hauppauge Computer Works and Pinnacle Systems. Our desktop storage solutions also compete against products using
alternative technologies, such as flash drives and removable media storage, which are available from a variety of companies.

Backlog

Due to industry practice that allows customers to change or cancel orders with limited advance notice prior to shipment, we do not believe that backlog as of any
particular date is indicative of future sales. Our backlog for our continuing operations at March 31, 2006 was approximately $21.5 million, consisting of $20.2 million related to
our DPS segment and $1.3 million related to our DSG segment. Our backlog at March 31, 2005 was approximately $25.3 million (including our backlog related to our IBM i/p Series
RAID and systems businesses that were discontinued in fiscal 2006). We typically receive orders for our products within two weeks or less of the desired delivery date and most orders are subject to
rescheduling and/or cancellation with little or no penalty. We maintain remote inventory locations at many of our major OEMs sites. Product ordering and delivery occur when the OEM customer accepts
our product into their inventory.

Manufacturing

Beginning in the fourth quarter of fiscal 2006, we employed Sanmina-SCI Corporation to manufacture the majority of our products. We employ Surface
Mount Technology Corporation, or SMTC, to manufacture certain of our ServeRAID products that are sold to IBM. We believe that SMTC and Sanmina-SCI will be able to meet our anticipated
needs for both current and future technologies.

Our final assembly and test operations are performed by Amkor Technology and Advanced Semiconductor Engineering.

Intellectual Property

We seek to establish and maintain our proprietary rights in our technology and products through the use of patents, copyrights, trademarks and trade secret laws.
We encourage our engineers to document patentable inventions, and we have applied for and continue to apply for patents in the United States and in foreign countries. As of March 31, 2006, we
had 375 issued patents, expiring between 2007 and 2024, covering various aspects of our technologies. In addition, the Adaptec name and logo are trademarks or registered trademarks of ours in the
United States and other countries. We believe our patents and other intellectual property rights have value, but we do not consider any single patent to be essential to our business. We also seek to
maintain our trade secrets and confidential information by non-disclosure policies and through the use of appropriate confidentiality agreements.

In
May 2000, we entered into a patent cross-license agreement with IBM. Under the agreement, we received a release from infringement claims prior to January 1, 2000 and
received the right to use certain of IBM's patents through June 30, 2004. In consideration, we paid, in annual installments, an aggregate patent fee of $13.3 million through
June 30, 2004, and we granted IBM a license to use all of our patents for the same period. In March 2002, the patent cross-license agreement was amended to extend the term to
June 30, 2007.

Research and Development

We continually enhance our existing products and develop new products to meet changing customer demands. The high technology industry is characterized by rapid
technological innovation, evolving industry standards, changes in customer requirements and new product introductions and enhancements. We believe that our future performance will depend in large part
on our ability to maintain and enhance our current product line, develop new products that achieve market acceptance, maintain competitiveness and meet an expanding range of customer requirements. To
achieve this objective, we intend to continue to leverage our technical expertise and product innovation capabilities to address storage-access products across a broad range of users and platforms. We
also expect to continue to make acquisitions and investments where appropriate. We have opened a research and development center in Bangalore, India and anticipate expanding the facility throughout
2007.

Approximately
one-third of our employees are engaged in research and development. In fiscal 2006, 2005 and 2004, our research and development expenses were
$60.9 million, or 20% of total revenues, $86.5 million, or 23% of total revenues, and $95.6 million, or 24% of total revenues, respectively. Research and development expenses
primarily consist of salaries and related costs of employees engaged in ongoing research, design and development activities, amortization of purchased technology and subcontracting costs.

We
entered into two strategic alliances in fiscal 2005 with ServerEngines and Vitesse related to a portion of our ASIC development. These alliances are further discussed in "Management's
Discussion and Analysis of Financial Condition and Results of Operations."

We
anticipate that we will continue to have significant research and development expenditures in the future in order to continue to offer innovative, high-quality products
and services to maintain and enhance our competitive position. Our investment in research and development primarily focuses on developing new products for external storage, storage software and server
storage markets. We also invest in research and development of new technologies, including iSCSI, SATA and Serial Attached SCSI.

Environmental Laws

Certain of our operations involve the use of substances regulated under various federal, state and international environmental laws. It is our policy to apply
strict standards for environmental protection to sites inside and outside the United States, even if not subject to regulations imposed by local governments.

The
European Parliament has enacted the Restriction on Use of Hazardous Substances Directive, or RoHS Directive, which restricts the sale of new electrical and electronic equipment
containing certain hazardous substances, including lead, which is currently used in some of our products. We are working to eliminate lead from products we put on the market by July 1, 2006 as
required by the RoHS Directive. The costs associated with compliance may negatively impact our results of operations and competitive position. For example, in fiscal 2006, we had an excess inventory
expense of $1.9 million related to the transition of our products to comply with the RoHS Directive. We are also working with our suppliers to redesign or reformulate their components
containing lead to reduce or eliminate lead in our products. Based upon current information available to us, we believe that we will be able to comply with the RoHS Directive within the applicable
time period. However, if we do not comply with
this Directive, we may suffer a loss of revenue, be unable to sell in certain markets or countries and suffer competitive disadvantage.

Employees

As of March 31, 2006, we had 1,128 employees. We believe that we currently have favorable employee relations. None of our employees are represented by a
collective bargaining agreement, nor have we ever experienced work stoppages.

Item 1A.Risk Factors

Our business faces significant risks. The risks described below may not be the only risks we face. Additional risks that we do not yet know of or that we
currently think are immaterial may also impair our business operations. If any of the events or circumstances described in the following risks actually occurs, our business, financial condition or
results of operations could suffer, and the trading price of our common stock could decline.

The impact of ongoing contract negotiations with our large OEM customers, industry technology transitions and market acceptance of our new
products could cause our quarterly revenues to continue to decline.Our quarterly revenues have declined in each of the last two quarters and may continue to
decline. We depend on a small number of large OEM customers for a significant portion of our revenues, and we are engaged in ongoing contract negotiations concerning product specifications and price.
These negotiations may prove to be unfavorable. In addition, we are in the midst of an industry transition from parallel to serial connectivity and the revenue we generate from sales of our serial
products may not grow at a fast enough rate to offset of declines in sales of our parallel products. Furthermore, although we are developing new products and technologies to replace our legacy
products and technologies these new products and technologies may not gain sufficient market acceptance or contribute significantly to revenue. These factors, individually or in the aggregate, could
cause our quarterly revenues to continue to decline.

We depend on contract manufacturers and subcontractors, and if they fail to meet our manufacturing needs, it could delay shipments of our
products and result in the loss of customers.We rely on contract manufacturers for manufacturing of our products and subcontractors for the assembly and packaging
of the integrated circuits included in our products. On December 23, 2005 we entered into a three-year contract manufacturing agreement with Sanmina-SCI whereby
Sanmina-SCI upon the closing of the transaction on January 9, 2006, assumed manufacturing operations of a majority of our products. If the transition of the manufacturing facilities does
not go as expected it could result in loss of customers or revenue, which would have an adverse effect on our financial results. We have no long-term agreements with our assembly and
packaging subcontractors. We also employ Amkor Technology and Advanced Semiconductor Engineering for our final assembly and test operations related to our ASIC products. We cannot assure you

11

---



these
subcontractors will continue to be able and willing to meet our requirements for these components or services. Any significant disruption in supplies from or degradation in the quality of
components or services supplied by, these contract manufacturers and subcontractors could delay shipments and result in the loss of customers or revenues, which could have an adverse effect on our
financial results.

Actions that we have taken and the actions that we are considering could adversely affect our business and financial results in the
short-term, and may not have the long-term beneficial results that we intend.Our new management team is continuing to perform a thorough
analysis of our operations, which it initiated in the first quarter of fiscal 2006, and has begun making a detailed plan to support our corporate strategy. This analysis of our operations includes a
review of all aspects of our business, including our product portfolio, our relationships with strategic partners and our research and development focus. To date, we have implemented the steps
described in "BusinessOverview," set forth above in Part I, Item 1 of this Annual Report on Form 10-K.

The
actions that we have taken and the actions that we are considering could adversely affect our business and financial results in the short-term, may not have the
long-term beneficial results that we intend and could result in the following:



If we are unable to successfully complete the divestiture of our systems business it could result in an adverse effect on our business and
financial results.Completing the divestiture of our systems business (which includes substantially all of the operating assets that were obtained through the Snap
Appliance and Eurologic Systems acquisitions) could cause significant diversions of management time and resources. In addition, if the net proceeds of any such sale, prove to be less than we
anticipate, it could lead to an additional impairment charge against our assets. Additionally, customers for our systems products could be reluctant to continue to buy from us due to the uncertainty
caused by the planned divestiture. We may not be successful in selling the systems business on terms that are acceptable to us or might not be able to find a buyer for the business. We may not be
successful in overcoming these risks or any other problems encountered in connection with this divesture which may adversely affect our business, financial position and operating results.

Our operating results have fluctuated in the past, and are likely to continue to fluctuate, and if our future results are below the
expectations of investors or securities analysts, the market price of our common stock would likely decline significantly.Our quarterly operating results have
fluctuated in the past, and are likely to vary significantly in the future, based on a number of factors related to our industry and the markets for our products. Factors that are likely to cause our
operating results to fluctuate include those discussed in this Risk Factors section. In fiscal 2006, our operating results were materially impacted by unusual charges, such as a goodwill impairment
charge of $90.6 million.

Our
operating expenses are largely based on anticipated revenues, and a large portion of our expenses, including facility costs and salaries, are fixed in the short term. As a result,
lower than

12

---



anticipated
revenues for any reason could cause significant variations in our operating results from quarter to quarter.

Due
to the factors summarized above, and the other risks described in this section, we believe that you should not rely on period-to-period comparisons of our
financial results as an indication of our future performance. In the event that our operating results fall below the expectations of market analysts or investors, the market price of our common stock
could decline substantially.

Our operating results may be adversely affected by unfavorable economic and market conditions and the uncertain geopolitical
environment.Adverse economic conditions in some markets may impact our business, which could result in:



Demand
for our products would likely be negatively affected if demand in the server and network storage markets declines. For example, demand in the server market declined slightly in
fiscal 2002 and fiscal 2003, which contributed to a decline in our net revenues. It is difficult to predict future server sales growth, if any. In addition, other technologies may replace the
technologies used in our existing products and the acceptance of our products using new technologies in the market may not be widespread, which could adversely affect our revenues.

Because our sales are made by means of standard purchase orders rather than long-term contracts, if demand for our customers'
products declines or if our customers do not control their inventories effectively, they may cancel or reschedule shipments previously ordered from us or reduce their levels of purchases from
us.The volume and timing of orders received during a quarter are difficult to forecast. Our customers generally order based on their forecasts and they frequently
encounter uncertain and changing demand for their products. If demand falls below such forecasts or if our customers do not control their inventories effectively, they may cancel or reschedule
shipments previously ordered from us. Our customers have from time to time in the past canceled or rescheduled shipments previously ordered from us, and we cannot assure you that they will not do so
in the future. In addition, because our sales are made by means of standard purchase orders rather than long-term contracts, we cannot assure you that these customers will continue to
purchase quantities of our products at current levels, or at all. Historically, we have set our operating budget based on forecasts of future revenues because we do not have significant backlog.
Because much of our operating budget is relatively fixed in the short-term, if revenues do not meet our expectations, then our financial results will be adversely affected.

We depend on a few key customers and the loss of any of them could significantly reduce our revenues.Historically, a small number of our customers has accounted for a significant portion of our revenues. During fiscal 2006, sales to the ten OEM and distribution customers from which we
received the greatest revenues accounted for approximately 92% of our total revenues. In addition, IBM and Dell represented 30% and 16%, respectively, of our total revenues in fiscal 2006. We believe
that our major customers continually evaluate whether or not to purchase products from alternate or additional sources. Additionally, customers' economic and market conditions frequently change.
Accordingly, we cannot assure you that a major customer will not reduce, delay or eliminate its purchases from us, which would likely cause our revenues to decline. In addition, we do not carry credit
insurance on our accounts receivables and any difficulty in collecting outstanding amounts due from our customers, particularly customers that place larger orders or experience financial difficulties,
could adversely affect our revenues

13

---



and
our net income. Because our sales are made by means of standard purchase orders rather than long-term contracts, we cannot assure you that these customers will continue to purchase
quantities of our products at current levels, or at all.

If there is a shortage of components used in our customers' products, our sales may decline, which could adversely affect our results of
operations and financial position.If our customers are unable to purchase certain components which are embedded into their products, their demand for our products
may
decline. In addition, we or our customers may be impacted by component shortages if components that comply with the RoHS Directive are not available. Similar shortages of components used in our
products or our customers' products could adversely affect our net revenues and financial results in future periods.

We may be subject to a higher effective tax rate that could negatively affect our results of operations and financial
position.Historically our effective tax rate was benefited by a Singapore tax holiday relating to certain of our products. As a result of the contract
manufacturing agreement that we entered into with Sanmina-SCI, we will no longer qualify for this holiday. If the alternative plans we have developed to reduce our effective tax rate are
not successful, our effective tax rate could increase, which would adversely affect our financial results.

We
held approximately $88.2 million of cash, cash equivalents and marketable securities at our subsidiary in Singapore at March 31, 2006. During the fourth quarter of
fiscal 2005, we repatriated $360.6 million of cash from Singapore to the United States in connection with the American Jobs Creation Act of 2004 which provides a one-time deduction
of 85% for certain dividends from controlled foreign corporations. If the amount repatriated does not qualify for the one-time deduction, we could incur additional income taxes at up to
the United States Federal statutory rate of 35%, which would negatively affect our results of operations and financial condition.

Our dependence on new products may cause our net revenues to fluctuate or decline.Our future success
significantly depends upon our completing and introducing enhanced and new products at competitive prices and performance levels in a timely manner. The success of new product introductions depends on
several factors, including the following:



Our
product life cycles in each of our segments may be as brief as 12 months. As a result, we believe that we will continue to incur significant expenditures for research and
development in the future. We may fail to identify new product opportunities and may not develop and bring new products to market in a timely manner. In addition, products or technologies developed by
others may render our products or technologies obsolete or noncompetitive, or our targeted customers may not select our products for design or integration into their products. The failure of any of
our new product development efforts could have an adverse effect on our business and financial results.

We
have introduced RAID-enabled products based on the next generation SATA technology and delivered our products based on Serial Attached SCSI technology to certain major
OEMs for testing and integration. We will not succeed in generating significant revenues from our new SATA and Serial Attached SCSI technology products if the market does not adapt to these new
technologies, which would, over time, adversely affect our net revenues and operating results.

14

---



Our reliance on industry standards and technological changes in the marketplace may cause our net revenues to fluctuate or
decline.The computer industry is characterized by various, evolving standards and protocols. We design our products to conform to certain industry standards and
protocols such as the following:

| | Technologies:        ATA
        Fibre channel
        FireWire/1394
        IPsec
        iSCSI
        PCI
        PCI-Express
        PCI-X |         RAID
        Serial Attached SCSI
        SATA
        SCSI
        SMI-S
        Ultra DMA
        USB
| | ------------------------------------------------------------------------------------------------------------------------------------------------------ | ----------------------------------------------------------------------------------------------------------------------

| | Operating Systems:        Linux
        Macintosh
        Netware |         OS/2
        UNIX
        Windows
| | -------------------------------------------------------------------- | --------------------------------------------

If
user acceptance of these standards declines, or if new standards emerge, and if we do not anticipate these changes and develop new products, these changes could adversely affect our
business and financial results.

If we lose the cooperation of other hardware and software producers whose products are integral to ours, our ability to sustain or grow
our revenues could be adversely affected.We must design our products to operate effectively with a variety of hardware and software products supplied by other
manufacturers, including the following:



We
depend on significant cooperation from these manufacturers to achieve our design objectives and develop products that operate successfully with their products. These companies could,
from time to time, elect to make it more difficult for us to design our products for successful operability with their products. For example, if one or more of these companies were to determine that
as a result of competition or other factors our technology or products would not be broadly accepted by the markets we target, these companies may no longer work with us to plan for new products and
new generations of our products, which would make it more difficult to introduce products on a timely basis or at all. Further, some of these companies might decide not to continue to offer products
that are compatible with our technology and our

15

---



markets
could contract. If any of these events were to occur, our revenue and financial results could be adversely affected.

We are subject to various environmental laws and regulations that could impose substantial costs upon us and may adversely affect our
business.The European Parliament has enacted the RoHS Directive, which restricts the sale of new electrical and electronic equipment containing certain hazardous
substances, including lead that is currently used in some of our products. We are working to eliminate lead from our products in accordance with the timelines established in the RoHS Directive. The
costs associated with compliance may negatively impact our operating results and competitive position. For example, in fiscal 2006, we had an excess inventory expense of $1.9 million related to
the transition of our products to comply with the RoHS Directive. We are also working with our suppliers to redesign or reformulate their components containing lead to reduce or eliminate lead in our
products. If we are unable to comply with the RoHS Directive, we may suffer a loss of revenue, be unable to sell affected products in certain markets or countries and be at a competitive disadvantage.

The
European Parliament has also finalized the Waste Electrical and Electronic Equipment Directive, or WEEE Directive, which makes producers of electrical and electronic equipment
financially responsible for specified collection, recycling, treatment and disposal of past and future covered products. We may incur financial responsibility for the collection, recycling, treatment
or disposal of products covered under the WEEE Directive. Because the EU member states have not fully implemented the WEEE Directive, the nature and extent of the costs to comply and fees or penalties
associated with non-compliance are unknown at this time. Costs to comply with the WEEE Directive and similar future legislation, if applicable, may also include legal and regulatory costs
and insurance costs. We may also be required to take reserves for costs associated with compliance with these regulations.

We entered into strategic alliances with Vitesse for the development of our Serial Attached SCSI ROC product and with ServerEngines to
advance our development of iSCSI products, and if these companies fail to develop and bring new products to market in a timely manner, it could result in an adverse effect on our business and
financial results.In January 2005, we entered into a strategic alliance with Vitesse for it to develop and market the next generation of our Serial
Attached SCSI products. In March 2005, we entered into a
strategic alliance with ServerEngines to develop and market the next generation of our IP storage products, such as 10Gb iSCSI. Accordingly, we are at risk that Vitesse and ServerEngines may encounter
challenges in fulfilling their responsibilities under these alliances, such as timely completing and introducing new product designs, maintaining the quality of new products, minimizing product costs,
differentiating new products from those of our competitors and achieving market acceptance of our products. Vitesse has recently become subject to investigation by the SEC and the U.S. Attorney's
office in New York regarding its historical practices with respect to the granting of stock options, which has resulted in Vitesse terminating certain of their executives. To the extent that these
investigations cause disruptions in Vitesse's operations, or if we otherwise encounter issues with respect to our strategic alliances, it could have an adverse effect on our business and financial
results.

If we do not provide adequate support during our customers' design and development stage, or if we are unable to provide such support in a
timely manner, we may lose revenues to our competitors.Certain of our products are designed to meet our customers' specifications and, to the extent we are not
able to meet these expectations in a timely manner or provide adequate support during our customers' design and development stage, our customers may choose to buy similar products from another
company. If this were to occur we may lose revenues and market share to our competitors.

If we are unable to compete effectively, our net revenues could be adversely affected.The markets
for all of our products are intensely competitive and are characterized by the following:



16

---





Consequently,
we must continue to enhance our products on a timely basis to keep pace with market demands. If we do not do so, or if our competition is more effective in developing
products that meet the needs of our existing and potential customers, we may lose market share and not participate in the future growth of our target markets. For example, intense competition in the
transition from products employing Ultra 160 technology to products employing Ultra 320 technology has adversely affected revenues from our SCSI products. Our future success will depend on the level
of acceptance of our RAID products and products based on the next generation SATA and Serial Attached SCSI technologies by new and existing customers. In addition, we expect that our future success
will depend significantly on our ability to participate in the ongoing development of the network storage market in which we face intense competition from other companies that are also focusing on
networked storage products.

We
cannot assure you that we will have sufficient resources to accomplish all of the following:



As part of our overall strategy we may make acquisitions and enter into strategic alliances. Costs associated with these acquisitions or
strategic alliances may adversely affect our results of operations, which could be exacerbated if we are unable to integrate the acquired companies, products or
technologies.As part of our overall strategy we may acquire or invest in complementary companies, products or technologies and enter into strategic alliances with
other companies. In order to be successful in these activities, we must:



The
benefits of acquisitions or strategic alliances may prove to be less than anticipated and may not outweigh the costs reported in our financial statements. For example, during fiscal
2006, we sold the IBM i/p Series RAID business for a loss of $2.3 million. Further, we plan to divest the remainder of our systems business, which includes certain assets obtained
through the Snap Appliance acquisition. During the fourth quarter of fiscal 2006, we recorded an impairment charge of $10.0 million to reduce these long-lived assets to fair value,
less cost to sell.

Completing
any potential future acquisitions or strategic alliances could cause significant diversions of management time and resources. If we acquire new businesses, products or
technologies in the future, we may be required to assume warranty claims or other contingent liabilities, including liabilities unknown at the time of acquisition, and amortize significant amounts of
other intangible assets and, over time, recognize significant charges for impairment of goodwill, other intangible assets or other losses. If we consummate any potential future acquisitions in which
the consideration consists of stock or other

17

---



securities,
our existing stockholders' ownership may be significantly diluted. If we proceed with any potential future acquisitions in which the consideration is cash, we may be required to use a
substantial portion of our available cash. In addition, we may be required to invest significant resources in order to perform under a strategic alliance or to complete an acquisition, which could
adversely affect our results of operations, at least in the short-term, even if we believe the strategic alliance or acquisition will benefit us in the long-term. We may not be
successful in overcoming these risks or any other problems encountered in connection with these or other business combinations, investments or strategic alliances. These transactions may adversely
affect our business, financial position and operating results.

Product quality problems could lead to reduced revenues and gross margins.We produce highly complex
products that incorporate leading-edge technologies, including both hardware and software. Software often contains "bugs" which can interfere with expected operations. We cannot assure you
that our pre-shipment testing programs will be adequate to detect all defects which might interfere with customer satisfaction, reduce sales opportunities, or affect our gross margins if
the costs of remedying the problems exceed reserves established for that purpose. An inability to cure a product defect could result in the failure of a product line, and withdrawal, at least
temporarily, from a product or market segment, damage to our reputation, inventory costs, product reengineering expenses, and a material impact on revenues and gross margins.

We currently purchase all of the finished production silicon wafers used in our products from wafer suppliers, and if they fail to meet
our manufacturing needs, it would delay our production and our product shipments to customers and negatively affect our operations.Independent foundries
manufacture to our specifications all of the finished silicon wafers used for our products. We currently purchase finished production silicon wafers used in our products from Taiwan Semiconductor
Manufacturing Company, or TSMC, and IBM. The manufacture of semiconductor devices is sensitive to a wide variety of factors, including the following:



We
cannot assure you that manufacturing problems may not occur in the future. A shortage of raw materials or production capacity could lead our wafer suppliers to allocate available
capacity to other customers. Any prolonged inability to obtain wafers with competitive performance and cost attributes, adequate yields or timely deliveries would delay our production and our product
shipments, and could have an adverse effect on our business and financial results. We expect that our wafer suppliers will continually seek to convert their processes for manufacturing wafers to more
advanced process technologies. Such conversions entail inherent technological risks that can affect yields and delivery times. If for any reason the wafer suppliers we use are unable or unwilling to
satisfy our wafer needs, we will be required to identify and qualify additional suppliers. Additional wafer suppliers may be unavailable, may take significant amounts of time to qualify or may be
unable to satisfy our requirements on a timely basis.

We depend on the efforts of our distributors, which if reduced, could result in a loss of sales of our products in favor of competitive
offerings.We derived approximately 38% of our revenues for fiscal 2006 from independent distributor and reseller channels. Our financial results could be
adversely affected if our relationships with these distributors or resellers were to deteriorate or if the financial condition of these distributors or resellers were to decline.

18

---



Our
distributors generally offer a diverse array of products from several different manufacturers. Accordingly, we are at risk that these distributors may give higher priority to selling
products from other suppliers. A reduction in sales efforts by our current distributors could adversely affect our business and financial results. For example, some of our distributors have threatened
to stop selling our products or make pricing of our products non-competitive if we do not agree to absorb
their costs to comply with the RoHS and WEEE Directives with respect to our products. Our distributors build inventories in anticipation of future sales, and if such sales do not occur as rapidly as
they anticipate, our distributors will decrease the size of their product orders. If we decrease our price protection or distributor-incentive programs, our distributors may also decrease their orders
from us. In addition, we have from time to time taken actions to reduce levels of products at distributors and may do so in the future. These actions may affect our net revenues and negatively affect
our financial results.

If we do not meet our restructuring objectives, we may have to implement additional plans in order to reduce our operating costs and may, as a result, incur
additional material restructuring charges.We have implemented several restructuring plans to reduce our operating costs in fiscal 2006, fiscal 2005 and fiscal
2004, and recorded related restructuring charges of $10.4 million, $5.9 million and $4.3 million, respectively. The plans included primarily the reduction of our workforce and the
consolidation of our manufacturing operations in Singapore. The goals of these plans were to support future growth opportunities, focus on investments that grow revenues and increase operating
margins. If we do not meet our restructuring objectives, we may have to implement additional restructuring plans to reduce our operating costs, which could cause us to incur material restructuring
charges. Further, these restructuring plans may not achieve the original goals we had in implementing them due to such factors as significant costs or restrictions on workforce reductions that may be
imposed in some international locales and a potential adverse effect on employee capabilities that could harm our efficiency and our ability to act quickly and effectively in the rapidly changing
technology markets in which we sell our products.

Some of our products contain "open source" software, and any failure to comply with the terms of one or more of these open source licenses
could negatively affect our business.Some of our products are distributed with software licensed by its authors or other third parties under so-called
"open source" licenses, including, for example, the GNU General Public License, or GPL, GNU Lesser General Public License, or LGPL, the Mozilla Public License, the BSD License, and the Apache License.
Some of those licenses may require as a condition of the license that we make available source code for modifications or derivative works we create based upon, incorporating, or using the open source
software, that we provide notices with our products, and/or that we license such modifications or derivative works under the terms of a particular open source license or other license granting third
parties certain rights of further use. If an author or other third party that distributes such open source software were to allege that we had not complied with the conditions of one or more of those
open source licenses, we could be required to incur legal expenses in defending against such allegations, and if our defenses were not successful we could be enjoined from distribution of the products
that contained the open source software and required to either make the source code for the open source software available, to grant third parties certain rights of further use of our software, or to
remove the open source software from our products, which could disrupt our distribution and sale of some of our products. In addition, if we combine our proprietary software with open source software
in a certain manner, we could under some of the open source licenses, be required to release the source code of our proprietary software. If an author or other third party that distributes open source
software were to obtain a judgment against us based on allegations that we had not complied with the terms of any such open source licenses, we could also be subject to liability for copyright
infringement damages and breach of contract for our past distribution of such open source software.

Our operations depend on key personnel, the loss of whom could affect the growth and success of our
business.In order to be successful, we must retain and motivate our executives, our principal engineers and other key employees, including those in managerial,
technical, marketing and information technology support positions. In particular, our product generation efforts depend on hiring and retaining qualified engineers.

19

---



Competition
for experienced management, technical, marketing and support personnel remains intense. For example, we transitioned certain research and development efforts to North Carolina, where we
have experienced significant competition in our efforts to attract and retain qualified software engineers. The loss of any of these key employees could have a significant impact on our operations. We
also must continue to motivate employees and keep them focused on our strategies and goals, which may be particularly difficult due to morale challenges posed by workforce reductions, the announcement
of the divestiture of the systems business and general uncertainty.

Our international operations involve risks, and may be subject to political or other non-economic barriers to our being able
to sell our products in certain countries, local economic conditions that reduce demand for our products among our target markets and potential disruption in the supply of necessary
components.Many of our subcontractors are primarily located in Asia and we have sales offices and customers located throughout Europe, Japan and other countries.
Our international operations and sales are subject to political and economic risks, including political instability, currency controls, changes in import/export regulations, tariffs and freight rates.
In addition, because our primary wafer supplier, TSMC, is located in Taiwan, we may be subject to certain risks resulting from political instability in Taiwan, including conflicts between Taiwan and
the People's Republic of China. These and other international risks could result in the creation of political or other non-economic barriers to our being able to sell our products in
certain countries, create local economic conditions that reduce demand for our products among our target market or expose us to potential disruption in the supply of necessary components or otherwise
adversely affect our ability to generate revenue and operate effectively.

We depend on third parties to transport our products.We rely on independent freight forwarders to
move our products between manufacturing plants and our customers. Any transport or delivery problems because of their errors, or because of unforeseen interruptions in their activities due to factors
such as strikes, political instability, terrorism, natural disasters and accidents, could adversely affect our business, financial condition and results of operations and ultimately impact our
relationship with our customers.

If the carrying value of our long-lived assets is not recoverable, an impairment loss must be recognized which would adversely
affect our financial results.Certain events or changes in circumstances would require us to assess the recoverability of the carrying amount of our
long-lived assets. For example, in fiscal 2006, we recorded a goodwill impairment charge of $90.6 million related to our DPS segment. In fiscal 2005, we recorded a goodwill
impairment charge of $52.3 million related to our former Channel segment. In fiscal 2004, we recorded an impairment charge of $5.0 million related to certain properties classified as
held-for sale and a charge of $1.0 million relating to the decline in value of a minority investment. We will continue to evaluate the recoverability of the
carrying amount of our long-lived assets, and we may incur substantial impairment charges which could adversely affect our financial results.

If actual results or events differ materially from those contemplated by us in making estimates and assumptions, our reported financial
condition and results of operations for future periods could be materially affected.The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and
accompanying notes. For example, we have identified key accounting estimates in our Critical Accounting Policies in our Annual Report on Form 10-K for the fiscal year ended
March 31, 2006, which includes revenue recognition, inventory, goodwill and income taxes. In addition, Note 1 of the Notes to Consolidated Financial Statements in our Annual Report on
Form 10-K for the fiscal year ended March 31, 2006 describes the significant accounting policies essential to preparing our consolidated financial statements. The preparation
of these financial statements requires estimates and assumptions that affect the reported amounts and disclosures. Although we believe that our judgments and estimates are appropriate and correct,
actual future results may differ materially from our estimates.

If we are unable to protect and enforce our intellectual property rights, we may be unable to compete
effectively.Although we actively maintain and defend our intellectual property rights, we may be unable to adequately protect our proprietary rights. In addition,
the laws of certain territories in which our products are or may be developed, manufactured or sold, including Asia and Europe, may not protect our products and intellectual property rights to the
same extent as the laws of the United States. Because we conduct a substantial portion of our operations outside of the United States and sell to a worldwide customer base, we are more dependent on
our ability to protect our intellectual property in international environments than would be the case if a larger portion of our operations were domestic.

Despite
our efforts, we may be unable to prevent third parties from infringing upon or misappropriating our intellectual property, which could harm our business and ability to compete
effectively. We have from time to time discovered counterfeit copies of our products being manufactured or sold by others. Although we have programs to detect and deter the counterfeiting of our
products, significant availability of counterfeit products could reduce our revenues and damage our reputation and goodwill with customers.

Third parties may assert infringement claims against us, which may be expensive to defend and could divert our
resources.From time to time, third parties assert exclusive patent, copyright and other intellectual property rights to our key technologies, and we expect to
continue to receive such claims in the future. For example, in fiscal 2005, we, Nevada SCSI Enterprises, Inc. and Thomas A. Gafford (jointly, "NSE") entered into a license and release
agreement, pursuant to which we paid NSE $1.7 million as a one-time, fully paid-up license fee to settle NSE's claims that some of our products infringed certain
patents. In addition, we entered into a patent cross-license agreement with IBM in May 2000. Under this agreement, which was amended in March 2002, we received a release from
infringement claims prior to January 1, 2000 and received the right to use certain of IBM's patents through June 30, 2007. In consideration, we paid, in annual installments, an aggregate
patent fee of $13.3 million through June 30, 2004. The risks of our receiving additional claims from third parties may be increased in periods such as the one that we are currently
entering where we are beginning to offer product lines employing new technologies relative to our existing products.

We
cannot assure you that third parties will not assert other infringement claims against us, directly or indirectly, in the future, that assertions by third parties will not result in
costly litigation or that we would prevail in such litigation or be able to license any valid and infringed intellectual property from third parties on commercially reasonable terms. These claims may
be asserted in respect of intellectual property that we own or that we license from others. In addition to claims brought against us by third parties, we may also bring litigation against others to
protect our rights. Intellectual property litigation, regardless of the outcome, could result in substantial costs to us and diversion of our resources, and could adversely affect our business and
financial results.

We may be required to pay additional federal income taxes which could negatively affect our results of operations and financial
position.On December 15, 2000, we received a statutory notice of deficiency from the IRS with respect to our Federal income tax return for fiscal 1997. We
filed a Petition with the United States Tax Court on March 14, 2001, contesting the asserted deficiencies and settlement agreements have been filed with the United States Tax Court on all but
one issue. In addition, the IRS is currently auditing our Federal income tax returns for fiscal 1998 through fiscal 2003. We have resolved all issues for fiscal 1998 through fiscal 2001 other than the
rollover impact of any potential resolution on the remaining fiscal 1997 issue and tax credits that were generated but not used in subsequent years that may be carried back. While we believe we have
meritorious defenses against the asserted deficiencies and any proposed adjustments, and that sufficient taxes have been provided, we cannot predict the final outcome of these matters, and the final
resolution could adversely affect our results of operations and financial position.

We may be engaged in legal proceedings that could cause us to incur unforeseen expenses and could occupy a significant amount of our
management's time and attention.From time to time we are subject to litigation or

21

---



claims
that could negatively affect our business operations and financial position. Such disputes could cause us to incur unforeseen expenses, could occupy a significant amount of our management's
time and attention, and could negatively affect our business operations and financial position.

We have in the past financed a portion of our capital expenditure needs from capital market financing, and if we need to seek additional
financing, it may not be available on favorable terms.In order to finance strategic acquisitions, capital asset acquisitions and other general corporate needs, we
have in the past relied, in part, on the capital markets. Historically, we have been able to access capital markets, but this does not necessarily guarantee that we will be able to access these
markets in the future or at terms that are acceptable to us. The availability of capital in these markets is affected by several factors, including geopolitical risk, the interest rate environment and
the condition of the economy as a whole. In addition, our own operating performance, capital structure and expected future performance impacts our ability to raise capital. For example, in the third
quarter of fiscal 2006, Standard and Poor's Ratings Services downgraded our subordinated debt rating from B- to CCC+. We believe that our current cash, cash equivalents,
short-term investments and future cash provided by operations will be sufficient to fund our needs for at least the next twelve months. However, if our operating performance falls below
expectations, we may need additional funds, which may not be available on favorable terms, if at all.

We are exposed to fluctuations in foreign currency exchange rates.Because a significant portion of
our business is conducted outside the United States, we face exposure to adverse movements in non-United States currency exchange rates. These exposures may change over time as business
practices evolve and could have an adverse impact on our financial results and cash flows. Historically, our exposures have related to non-dollar-denominated operating expenses in Europe
and Asia. We began Euro-denominated sales to our distribution customers in the European Union in the fourth quarter of fiscal 2003. An increase in the value of the dollar could
increase the real cost to our customers of our products in markets outside the United States where we sell in dollars, and a weakened dollar could increase the cost of local operating expenses and
procurement.

We hold minority interests in privately held venture funds, and if these venture funds face financial difficulties in their operations,
our investments could be impaired.We continue to hold minority interests in privately held venture funds. At March 31, 2006, the carrying value of such
investments aggregated $2.9 million. We have also committed to provide additional funding of up to $0.2 million. These investments are inherently risky because these venture funds invest
in companies that may still be in the development stage or depend on third parties for financing to support their ongoing operations. In addition, the markets for the technologies or products of these
companies are typically in the early stages and may never develop. If these companies do not have adequate cash funding to support their operations, or if they encounter difficulties developing their
technologies or products, the venture funds' investments in these companies may be impaired, which in turn, could result in impairment of our investment in these venture funds.

Our spin-off of Roxio Inc., which is now known as Napster Inc., may have potential subsequent tax liabilities
that could negatively affect our results of operations.Pursuant to our distribution of the Roxio, Inc. common stock, we received an opinion from
PricewaterhouseCoopers LLP, or PwC, regarding the tax-free nature of the transaction to us and to our stockholders under Section 355 of the Internal Revenue Code. The validity of
the PwC opinion relating to the qualification of the distribution as a tax-free transaction is subject to factual representations and assumptions. We are not aware of any facts or
circumstances that would cause such representations and assumptions to be untrue. In addition, the opinion of PwC is not binding on the IRS. If Napster or we fail to conform to the requirements set
forth in the IRS regulations, it could cause the distribution to be taxable to us and to our stockholders, and our financial results could be adversely affected.

Changes in securities laws and regulations have increased and may continue to increase our
costs.Changes in the laws and regulations affecting public companies, including the provisions of the Sarbanes-Oxley Act of 2002 and rules promulgated by the
Securities and Exchange Commission, have increased and may

22

---



continue
to increase our expenses as we evaluate the implications of these rules and devote resources to respond to their requirements. In particular, we incurred additional administrative expense to
implement Section 404 of the Sarbanes-Oxley Act, which requires management to report on, and our independent registered public accounting firm to attest to, our internal control over financial
reporting.

In
addition, the Nasdaq National Market, on which our common stock is listed, has also adopted comprehensive rules and regulations relating to corporate governance. These laws, rules and
regulations have increased and will continue to increase the scope, complexity and cost of our corporate governance, reporting and disclosure practices. We also expect these developments to make it
more difficult and more expensive for us to obtain director and officer liability insurance in the future, and we may be required to accept reduced coverage or incur substantially higher costs to
obtain coverage.
Further, our board members, Chief Executive Officer and Chief Financial Officer could face an increased risk of personal liability in connection with the performance of their duties. As a result, we
may have difficultly attracting and retaining qualified board members and executive officers, which would adversely affect our business.

Internal control deficiencies or weaknesses that are not yet identified could emerge.Over time we
may identify and correct deficiencies or weaknesses in our internal control over financial reporting and, where and when appropriate, report on the identification and correction of these deficiencies
or weaknesses. However, the internal control procedures can provide only reasonable, and not absolute, assurance that deficiencies or weaknesses are identified. Deficiencies or weaknesses that are not
yet identified could emerge, and the identification and corrections of these deficiencies or weaknesses could have a material impact on our results of operations.

Internal control issues that appear minor now may later become material weaknesses.We are required
to publicly report on deficiencies or weaknesses in our internal control over financial reporting that meet a materiality standard as required by law and related regulations and interpretations.
Management may, at a point in time, accurately categorize a deficiency or weakness as immaterial or minor and therefore not be required to publicly report such deficiency or weakness. Such
determination, however, does not preclude a change in circumstances such that the deficiency or weakness could, at a later time, become a material weakness that could have a material impact on our
results of operations.

We may encounter natural disasters, which could cause disruption to our employees or interrupt the manufacturing process for our
products.Our operations could be subject to natural disasters and other business disruptions, which could seriously harm our revenues and financial condition and
increase our costs and expenses. Our corporate headquarters are located in California, near major earthquake faults. Additionally, our primary wafer supplier, TSMC, is located in Taiwan, which has
experienced significant earthquakes in the past. A severe earthquake could cause disruption to our employees or interrupt the manufacturing process, which could affect TSMC's ability to supply wafers
to us, which would negatively affect our business and financial results. The ultimate impact on us and our general infrastructure of being located near major earthquake faults is unknown, but our net
revenues and financial condition and our costs and expenses could be significantly impacted in the event of a major earthquake.

Manmade problems such as computer viruses or terrorism may disrupt our operations and harm our operating
results.Despite our implementation of network security measures, our servers are vulnerable to computer viruses, break-ins and similar disruptions
from unauthorized tampering with our computer systems. Any such event could have an adverse effect on our business, operating results, and financial condition. In addition, the effects of war or acts
of terrorism could have an adverse effect on our business, operating results, and financial condition. In addition, as a company with headquarters and significant operations located in the United
States, we may be impacted by actions against the United States. We are predominantly uninsured for losses and interruptions caused by terrorist acts and acts of war.

We may experience significant fluctuations in our stock price, which may, in turn, significantly affect the trading price of our
convertible notes.Our stock has experienced substantial price volatility, particularly as a

23

---



result
of quarterly variations in our operating results, the published expectations of analysts and as a result of announcements by our competitors and us. In addition, the stock market has
experienced price and volume fluctuations that have affected the market price of many technology companies, in particular, and that have often been unrelated to the operating performance of such
companies. In addition, the price of our securities may also be affected by general global, economic and market conditions and the cost of operations in one or more of our product markets. While we
cannot predict the individual effect that these factors may have on the price or our securities, these factors, either individually or in the aggregate, could result in significant variations in the
price of our common stock during any given period of time. These fluctuations in our stock price also impact the price of our outstanding convertible securities and the likelihood of the convertible
securities being converted into our common stock.

Item 2.Properties

As of March 31, 2006, we owned and leased various properties in the United States and in foreign countries totaling approximately 724,000 square feet, of
which approximately 322,000 was leased/subleased or available to lease/sublease to third parties. The building leases expire at varying dates through fiscal 2012 and include renewals at our option.
Our headquarters are located in Milpitas, California, which includes research and development, technical support, sales, marketing and administrative functions. In addition, we lease buildings in
Colorado, Florida, Minnesota, New Hampshire, North Carolina, Texas and Washington. We use these properties primiarly for research and development, technical support, sales and marketing functions.
Internationally, we operate in Australia, China, England, Germany, India and Japan. We use these properties primarily for research and development, technical design, technical support and sales
functions.

The
table below is a summary of the facilities we owned and leased at March 31, 2006:

We
do not separately track our major facilities by segments nor are the segments evaluated under these criteria. Substantially all of the properties are used at least in part by more
than one of our segments and we retain the flexibility to use each of the properties in whole or in part for each of the segments.

We
believe our existing facilities and equipment are well maintained and in good operating condition, and we believe our facilities are sufficient to meet our needs for the foreseeable
future. Our future facilities requirements will depend upon our business, and we believe additional space, if required, can be obtained on reasonable terms.

Item 3.Legal Proceedings

We have been, or are, subject to IRS audits for our fiscal years 1994 through 2003. The fiscal 1994 through fiscal 1996 cycle, which is docketed in the United
States Tax Court, was resolved in December 2001. The outcome did not have a material adverse effect on our financial position or results of operations, as sufficient tax provisions had been
made. The final Tax Court stipulation will be filed when the subsequent audit cycles are completed. Tax credits that were generated but not used in subsequent years may be carried back to the fiscal
1994 to 1996 audit cycle.

On
December 15, 2000, we received a statutory notice of deficiency from the IRS with respect to our Federal income tax return for fiscal 1997. We filed a Petition with the United
States Tax Court on March 14, 2001, contesting the asserted deficiencies. Settlement agreements have been filed with the United States Tax Court on all but one issue. We believe that the final
outcome of all issues will not have a material adverse impact on our financial position or results of operations, as we believe that we have meritorious defenses against the asserted deficiencies and
any proposed adjustments and that we have made sufficient tax provisions. However, we cannot predict with certainty how these matters will be resolved and whether we will be required to make
additional payments.

In
addition, the IRS is currently auditing our Federal income tax returns for fiscal 1998 through fiscal 2003. In the third quarter of fiscal 2005, we resolved all issues for fiscal 1998
through fiscal 2001, other than the rollover impact of any potential resolution on the remaining fiscal 1997 issue and tax credits that were generated but not used in subsequent years that may be
carried back. We believe that we have provided sufficient tax provisions for these years and the ultimate outcome of the IRS audits will not have a material adverse impact on our financial position or
results of operations in future periods. However, we cannot predict with certainty how these matters will be resolved and whether we will be required to make additional tax payments.

We
are a party to other litigation matters and claims, including those related to intellectual property, which are normal in the course of our operations, and while the results of such
litigation matters and claims cannot be predicted with certainty, we believe that the final outcome of such matters will not have a material adverse impact on our financial position or results of
operations. However, because of the nature and inherent uncertainties of litigation, should the outcome of these actions be unfavorable, our business, financial condition, results of operations and
cash flows could be materially and adversely affected.

Item 7.Management's Discussion and Analysis of Financial Condition and Results of Operations

This "Management's Discussion and Analysis of Financial Condition and Results of Operations" section should be read in conjunction with the other sections of this
Annual Report on Form 10-K, including "Item 1: Business"; "Item 6: Selected Financial Data"; and "Item 8: Financial Statements and Supplementary Data." This
section contains a number of forward-looking statements, including statements regarding our intention to divest our systems business, revenues from our SCSI-based desktop products and our
liquidity in future periods. These forward-looking statements are based on our current expectations and could be affected by the uncertainties and risk factors described throughout this filing and
particularly in the "Risk Factors" set forth in Part I, Item 1A of this Annual Report on Form 10-K. Our actual results may differ materially, and these forward-looking
statements do not reflect the potential impact of any mergers, acquisitions or other business combinations that had not been completed as of June 9, 2006.

Overview

Our new management team is continuing to perform a thorough analysis of our operations, which it initiated in the first quarter of fiscal 2006, and has begun
implementing a detailed plan of our corporate strategy. This analysis of our operations includes a review of all aspects of our business, including our product portfolio, our relationships with
strategic partners and our research and development focus. To date, we have implemented the following steps:

The
actions that we have taken and the actions that we are considering could adversely affect our business and financial results in the short-term, may not have the
long-term beneficial results that we intend and could result in the following:



Our
future revenue growth remains largely dependent on the success of our data protection solutions, new OEM design wins and our products addressing new technologies (i.e., Serial
Attached SCSI, SATA and iSCSI).

Fiscal 2006 compared to Fiscal 2005

Revenues from our DPS segment decreased by $56.8 million in fiscal 2006 as compared to fiscal 2005 reflecting a decline in sales volumes and average
selling prices of our parallel SCSI products, which was partially offset by increased sales of our serial products and benefits associated with the renegotiation of a customer supply contract. The
decline in sales volumes of our SCSI products was primarily attributable to the transition from our Ultra 160 products to our Ultra 320 products in which we have a lower market share and a shift to
lower cost SATA solutions in which there is a more competitive market.

Revenues
from our DSG segment decreased by $4.4 million in fiscal 2006 compared to fiscal 2005 primarily due to the decline in sales volumes of our SCSI-based desktop
computer products. This decline was partially offset by increased sales of our digital media products and sales of storage products that were introduced in the fourth quarter of fiscal 2005. We expect
revenues from our DSG products to continue to decline as OEMs are incorporating other connectivity technologies directly into their products.

Fiscal 2005 compared to Fiscal 2004

Revenues from our DPS segment decreased by $19.3 million in fiscal 2005 as compared to fiscal 2004 reflecting a decline in sales volumes of our SCSI
products primarily attributable to the industry shortage of SCSI disk drives in the fourth quarter of fiscal 2005, the transition from our Ultra 160 products to Ultra 320 products and a change in the
sales mix of products incorporating our SCSI technology due to customers purchasing more software and chip products which generally have lower average selling prices compared to HBAs or other board
level SCSI products. This was partially offset by increased sales from products based on next generation SATA technology and external storage systems.

Revenues
from our DSG segment decreased by $5.1 million in fiscal 2005 as compared to fiscal 2004 as a result of the decline in sales volumes of our SCSI-based desktop
computer products and our digital media products, partially offset by increased sales of non-SCSI based connectivity and TV tuner products.

Our
North America revenues increased as a percentage of our total revenues in fiscal 2006 as compared to fiscal 2005 primarily as a result of benefits associated with the renegotiation
of a customer supply contract and increased sales related to a North American OEM, partially offset by a decline in channel sales in North America. Included in European revenues for fiscal 2006 was
$11.7 million of a last time buy customer order. Our North America revenues decreased as a percent of our total revenues in fiscal 2005 as compared to fiscal 2004 primarily as a result of
decreased sales related to a North American OEM.

A
small number of our customers account for a substantial portion of our revenues, and we expect that a limited number of customers will continue to represent a substantial portion of
our revenues for the foreseeable future. In fiscal 2006, IBM and Dell accounted for 30% and 16% of our total revenues, respectively. In fiscal 2005, IBM and Dell accounted for 24% and 15% of our total
revenues, respectively. In fiscal 2004, IBM and Dell accounted for 21% and 12% of our total revenues, respectively.

The
decline in gross margin in fiscal 2006 compared to fiscal 2005 was primarily due to changes in our product and customer mix, which led to lower average margins, fixed costs that were
distributed over lower revenue levels and an excess inventory expense of $1.9 million recorded in fiscal 2006 related to the transition of our products to comply with the European Union
Restriction on Use of Hazardous Substances Directive, or RoHS Directive. This was partially offset by decreased component costs and benefits associated with the renegotiation of a customer supply
contract. Our gross margins may be impacted in the future by the mix of OEM and channel revenue.

The
decline in gross margin in fiscal 2005 compared to fiscal 2004 was primarily due to changes in our product mix, which led to lower average margins, and negative margins associated
with our new
external storage products sold to IBM. Costs associated with our new external storage products sold to IBM impacted our gross margin by $5.2 million compared to the margin we expected to obtain
on these products.

Our
investment in research and development primarily focuses on developing new products for external storage, storage software and server storage markets. We also invest in research and
development of new technologies, including iSCSI, SATA and Serial Attached SCSI. A portion of our research and development expense fluctuates depending on the timing of major project costs such as
prototype costs.

The
decrease in research and development expense in fiscal 2006 as compared to fiscal 2005 was primarily a result of reduced headcount achieved as a result of the ServerEngines and
Vitesse strategic alliances we entered into in the fourth quarter of fiscal 2005, decreased infrastructure spending and reduced headcount as a result of restructuring programs implemented in fiscal
2005 and decreased deferred compensation charges in fiscal 2006 compared to fiscal 2005. Deferred compensation charges

represented
the vesting of assumed stock options in connection with our acquisition of Platys Communications, Inc., or Platys, in August 2001. Deferred compensation charges associated
with the Platys acquisition ceased in the first quarter of fiscal 2006.

The
decrease in research and development expense in fiscal 2005 as compared to fiscal 2004 was primarily a result of decreased infrastructure spending and reduced headcount as a result
of restructuring programs implemented in fiscal 2005 and 2004, the reduced headcount as a result of the Vitesse strategic alliance and decreased deferred compensation charges of $2.1 million in
fiscal 2005 compared to fiscal 2004. Deferred compensation charges represented the vesting of restricted stock, unvested cash and assumed stock options in connection with our Platys acquisition. This
was partially offset by costs associated with the development of the IBM DS300 and DS400 products.

As
our selling, marketing and administrative expense consists primarily of salaries, including commissions, our expense fluctuates based on changes to our revenue levels.

The
decrease in selling, marketing and administrative expense in fiscal 2006 as compared to fiscal 2005 was primarily a result of decreased spending due to lower revenues and reductions
of our workforce and infrastructure spending as a result of the restructuring plans we implemented in fiscal 2005 and the third quarter of fiscal 2006. This was partially offset by compensation of
$1.2 million recorded in the first quarter of fiscal 2006 related to retirement costs of our former Chief Executive Officer.

The
increase in selling, marketing and administrative expense in fiscal 2005 as compared to fiscal 2004 was primarily a result of increased deferred compensation charges of
$0.3 million representing the vesting of assumed stock options in connection with our Platys acquisition, and an increase in general corporate expenses related to acquisitions. This was
partially offset by decreased spending due to reductions of our workforce and infrastructure spending as a result of the restructuring plans implemented in fiscal years 2005 and 2004.

Acquisition-related
intangible assets include patents, core and existing technologies, covenants-not-to-compete, supply agreement, foundry agreement,
customer relationships, trade names, backlog and royalties. We amortize the acquisition-related intangible assets over periods which reflect the pattern in which the economic benefits of the assets
are expected to be realized, which is primarily using the straight-line method over their estimated useful lives, ranging from three months to five years.

The
decrease in amortization of acquisition-related intangible assets in fiscal 2006 compared to fiscal 2005 was due to intangible assets that became fully amortized in
August 2005 associated with our Platys acquisition and certain intangible assets that became fully amortized in fiscal 2005 associated with our acquisition of Eurologic Systems Group Limited in
April 2003.

During
fiscal 2006, 2005 and 2004, we implemented several restructuring plans which included reductions of our workforce and consolidation of operations. The goal of these plans was to
bring our operational expenses to appropriate levels relative to our net revenues, while simultaneously implementing extensive new company-wide expense-control programs. All expenses,
including adjustments, associated with our restructuring plans are included in "Restructuring charges" in the Consolidated Statements of Operations and are not allocated to segments but rather managed
at the corporate level. For further discussion on our restructuring plans, please refer to Note 9 to the Notes to Consolidated Financial Statements.

Fiscal 2006 Restructuring Plans

In the third and fourth quarters of fiscal 2006, management approved and initiated plans to restructure our operations by simplifying our infrastructure. These
restructuring plans eliminated certain duplicative resources in all functions of the organization worldwide, due in part, to the discontinued operations, the vacating of redundant facilities in order
to reduce our cost structure, and sale of our Singapore manufacturing facility.

Fiscal 2005 Restructuring Plans

In each quarter of fiscal 2005, we implemented restructuring plans (collectively called the fiscal 2005 restructuring provision) to streamline the corporate
organization, thereby reducing operating costs by consolidating duplicative resources in connection with the acquisition of Snap Appliance and the Vitesse strategic alliance and costs pertaining to
estimated future obligations for non-cancelable lease payments for excess facilities in Germany and United Kingdom. This resulted in a restructuring charge of $5.8 million, of which
$5.2 million related to the involuntary termination of employees in all functions of the organization and $0.6 million related to the estimated loss on our facilities. As of
March 31, 2006, we had utilized all of these charges and the plan is now complete.

Fiscal 2004 Restructuring Plans

In the fourth, third and second quarters of fiscal 2004, we implemented restructuring plans (collectively called the fiscal 2004 restructuring provision) to
consolidate primarily research and development resources, the involuntary termination of certain technical support, marketing and administrative personnel, the shutdown of our Hudson, Wisconsin
facility, and asset impairments associated with the identification of duplicative assets and facilities. As a result, we recorded a restructuring charge of $3.7 million, of which
$3.3 million related to severance and benefits to 30 employees. We recorded an adjustment to the fiscal 2004 restructuring provision of $0.2 million in fiscal 2005 as a reduction of
severance and benefits as actual results were lower than anticipated, offset by an adjustment of $0.6 million in fiscal 2004 related to the additional lease costs. As of March 31, 2006,
we had utilized all of these charges and the plan is now complete.

In addition, we recorded provision adjustments related to our fiscal 2003, fiscal 2002 and fiscal 2001 restructuring plans and Snap Appliance Acquisition-Related Restructuring Plan
(Note 9) in fiscal 2006, 2005 and 2004 for $1.0 million, $0.5 million and $0.3 million, respectively, primarily related to additional lease costs related to the estimated
loss on our facilities, which was partially offset by the reduction of severance and benefits as actual results were lower than anticipated.

Goodwill
is not amortized, but instead is reviewed annually and whenever events or circumstances occur which indicate that goodwill might be impaired. Impairment of goodwill is tested at
our reporting
unit level which is at our operating segment level, by comparing each segment's carrying amount, including goodwill, to the fair value of that segment. To determine fair value, our review process uses
the income or discounted cash flows approach and the market approach. In performing our analysis, we use the best information available under the circumstances, including reasonable and supportable
assumptions and projections. If the carrying amount of the segment exceeds its implied fair value, goodwill is considered impaired and a second step is performed to measure the amount of impairment
loss, if any.

In
connection with the reorganization of our segments in fiscal 2006, which is discussed above and in Note 16 to the Notes to Consolidated Financial Statements appearing in this
Annual Report on Form 10-K, an assessment of the recoverability of goodwill was performed. As a result of this review, we wrote-off our entire balance of goodwill of
$90.6 million in the second quarter of 2006. Factors that led to this conclusion included but were not limited to, industry technology changes experienced in the first half of fiscal 2006 such
as the shift from parallel to serial technology and the migration of core functionality to server chipsets; required increased investments that eventually led us to sell the IBM i/p Series RAID
business in fiscal 2006 and the decision to sell the systems business; continued losses associated with sales of systems to IBM; and general market conditions.

Based
on our annual review of goodwill in the fourth quarter of fiscal 2005, we recorded an impairment charge of $52.3 million related to our former Channel segment. Factors that
led to this conclusion included, but were not limited to, the negative impact of estimates of expected future income associated with increased costs related to recent acquisitions and business
alliances that occurred in fiscal 2005. These additional costs, along with industry technology transitions, placed significant risk on our ability to achieve and maintain profitability, and, therefore
adversely impacted our profitability forecasts.

Other
charges consisted of asset impairment charges related to certain properties or assets and our minority investments. Other charges also included charges associated with our
strategic alliances with ServerEngines and Vitesse.

On
December 23, 2005, we entered into a three-year contract manufacturing agreement with Sanmina-SCI whereby Sanmina-SCI, upon the closing of
the transaction of January 9, 2006, assumed manufacturing operations of Adaptec products. In addition, we sold certain manufacturing assets, buildings and improvements and inventory located in
Singapore with respect to printed circuit board

assemblies
and storage system manufacturing operations to Sanmina-SCI for $26.6 million (net of closing costs of $0.6 million) resulting in a loss on disposal of assets of
$1.6 million that was recorded in fiscal 2006 in "Other charges (gains)" on the Consolidated Statements of Operations.

On
March 16, 2005, we entered into a strategic alliance with ServerEngines to develop and market next-generation IP storage products. Under the terms of the alliance,
ServerEngines employed 33 of our former engineering employees and licensed certain technology and acquired certain assets related to our iSCSI and TCP/IP offload protocol engines. On
January 26, 2005, we entered into a strategic alliance with Vitesse to develop and market next-generation Serial Attached SCSI products. Under the terms of the alliance, Vitesse
employed 44 of our former engineering employees and licensed certain Serial Attached SCSI technology and assets related to our development of Serial Attached SCSI ROC products. As a result, we
incurred charges in fiscal 2005 of $0.9 million and $1.6 million for severance, benefits, loss on the sale of property and equipment and legal fees associated with the ServerEngines and
Vitesse alliances, respectively.

In
fiscal 2004, we recorded an impairment charge of $5.0 million to reduce the carrying value of certain properties classified as assets held for sale to fair value less cost to
sell. We decided to consolidate our properties in Milpitas, California to better align our business needs with existing operations and to
provide more efficient use of our facilities. As a result, two owned buildings, including associated building improvements and property, plant and equipment, were classified as assets held for sale
and were included in "Other current assets" in the Consolidated Balance Sheets at March 31, 2004 at their expected fair value less expected cost to sell. In October 2004, we completed
the sale of these properties that were previously classified as held for sale. Net proceeds from the sale of the properties aggregated $9.6 million, which exceeded our estimated fair value of
$6.8 million. As a result, a gain on the sale of the properties of $2.8 million was recorded in fiscal 2005 as a credit to "Other charges (gains)" in the Consolidated Statements of
Operations.

We
hold minority investments in non-public companies. We regularly monitor these minority investments for impairment and record reductions in the carrying values when
necessary. Circumstances that indicate an other-than-temporary decline include valuation ascribed to the issuing company in subsequent financing rounds, decreases in quoted
market price and declines in operations of the issuer. We recorded impairment charges of $1.0 million in fiscal 2004 related to a decline in the value of a minority investment deemed to be
other-than-temporary.

The
increase in interest and other income in fiscal 2006 as compared to fiscal 2005 was primarily due to higher interest rates earned on our cash, cash equivalents and marketable
securities in fiscal 2006
and a one-time fully paid-up license payment fee of $1.7 million to Nevada SCSI Enterprises, Inc. and Thomas A. Gaffird (jointly, "NSE"), which was recorded in
fiscal 2005, primarily for historical products that incorporated certain technology.

The
decrease in interest and other income in fiscal 2005 as compared to fiscal 2004 was primarily due to: (1) a gain recorded in fiscal 2004 of $49.3 million in relation to
a settlement with the former president of DPT; (2) lower interest income earned on our cash, cash equivalents and marketable securities related to lower average cash balances;
(3) realized losses on our cash, cash equivalents and marketable securities, of which $4.5 million primarily resulted from the liquidation of investments held by our Singapore subsidiary
in connection with the repatriation of undistributed earnings to the U.S.; and (4) a one-time fully paid-up license fee of $1.7 million to NSE, which was recorded
in fiscal 2005, primarily for historical products that incorporated certain technology. This was partially offset by losses of $6.5 million on the repurchase of our 3% Notes the redemption of
our 43/4% Notes in fiscal 2004 and a refund from the State Board of Equalization for prior qualifying sales and use tax payments of $0.7 million in fiscal 2005. For further
discussion on the settlement with the former president of DPT and NSE, please refer to Note 11 to the Notes to Consolidated Financial Statements.

For
fiscal 2006, we recorded an income tax provision of $1.6 million on a pre-tax loss of $113.1 million. Our fiscal 2006 effective income tax rate included an
increase in the valuation allowance for deferred tax assets of $14.6 million. In addition, our effective tax rate for fiscal 2006 differs from the combined United States federal and state
statutory income tax rate of 40% primarily due to acquisition
related impairment charges and losses incurred in foreign jurisdictions for which no tax benefit is derived.

We
had a valuation allowance for deferred tax assets of $91.5 million at March 31, 2006 as we determined that it was more likely than not that substantially all of our U.S.
deferred tax assets will not be realized. We continuously monitor the circumstances impacting the expected realization of our deferred tax assets on a jurisdiction by jurisdiction basis. At
March 31, 2006, our analysis of our deferred tax assets demonstrated that it was more likely than not that all of our U.S. deferred tax assets would not be realized. Factors that led to this
conclusion included, but were not limited to, our past operating results, cumulative tax losses in the U.S., and uncertain future income on a jurisdiction by jurisdiction basis.

On
October 22, 2004, the American Jobs Creation Act of 2004, also referred to as the Act, was signed into law. The Act created a temporary incentive for U.S. companies to
repatriate accumulated foreign earnings subject to certain limitations by providing a one-time deduction of 85% for certain dividends from controlled foreign corporations. In the fourth
quarter of fiscal 2005, we repatriated $360.6 million of undistributed earnings from Singapore to the United States, resulting in a tax liability of $17.6 million. The
one-time deduction is allowed to the extent that the repatriated amounts are used to fund a qualified Domestic Reinvestment Plan, as required by the Act. If we do not spend the repatriated
funds in accordance with our reinvestment plan, we may incur additional tax liabilities. We have not provided for U.S. deferred income taxes or foreign withholding taxes on the remaining undistributed
earnings of $257.2 million since these earnings are intended to be reinvested indefinitely. Although we do not have any current plans to repatriate the remaining undistributed earnings from our
Singapore subsidiary to our United States parent company, if we were to do so, additional income taxes at the combined United States Federal and state statutory rate of approximately 40% could be
incurred from the repatriation.

The
net tax benefit of $26.4 million for fiscal 2005 related to settled tax controversies, which includes discrete items totaling $31.9 million related to the amount and
methodology of resolving issues related to the IRS's audit of our federal income tax audits from fiscal 1998 through fiscal 2001, offset by changes in current pending IRS audits.

For
fiscal 2004, we recorded an income tax benefit of $30.8 million on pre-tax income of $47.4 million. Our fiscal 2004 effective income tax rate included a tax
benefit for the reduction in the valuation allowance of $21.6 million and the reduction of previously accrued tax related liabilities of $6.3 million. The valuation allowance for
deferred tax assets was established in fiscal 2002 as we determined that it was more likely than not that the deferred tax assets would not be realized. We continuously monitor the circumstances
impacting the expected realization of our deferred tax assets and the tax provisions established for fiscal years under IRS audit. At March 31, 2004, our analysis of our deferred tax assets
demonstrated that it was more likely than not that all of our deferred tax assets would be realized. Factors that led to this conclusion included, but were not limited to, expected future
income, which included the completion of key products based on serial technologies, and increased revenue opportunities, particularly for our systems products, and our historical success in managing
our deferred tax assets. In addition, our acquisitions and business alliances, together with our streamlined operations and revised product roadmaps, were expected to be accretive in future periods.
Accordingly, we released the valuation allowance and additional tax provision in the fourth quarter of fiscal 2004, based on our conclusion that it was more likely than not that the deferred tax
assets existing at March 31, 2004 would be realized. Our effective tax rate for fiscal 2004 also differed from the combined United States federal and state statutory income tax rate of 40%
primarily due to the tax benefits from our Singapore tax holiday, research and development credits, and the tax benefit applicable to the DPT purchase price adjustment.

Our
subsidiary in Singapore operated under a tax holiday through March 31, 2006. As the result of the divestiture of our manufacturing operations in Singapore, we are in the
process of terminating our tax holiday. We are currently making modifications to our international tax structure to reflect our revised foreign operations. We do not expect these changes, to cause our
worldwide effective tax rate to differ materially.

IBM i/p Series RAID Business:On September 30, 2005, we entered into a series of arrangements with IBM pursuant to
which we sold our IBM i/p Series RAID business to IBM for approximately $22.0 million plus $1.3 million for certain fixed assets. In addition, IBM purchased certain related inventory at
our net book value of $0.8 million. Expenses incurred in the transaction primarily included costs of approximately $0.5 million for legal and accounting fees. In addition, we accrued
$0.3 million for lease obligations. Under the terms of the agreements, we granted IBM a nonexclusive license to certain intellectual property and sold to IBM substantially all of the assets
dedicated to the engineering and manufacturing of RAID controllers and connectivity products for the IBM i/p Series RAID business. Under the terms of the nonexclusive license, IBM will pay us
royalties for the sale of our board-level products over the next six quarters, which will be recognized as contingent consideration in discontinued operations when earned. In fiscal 2006, we received
royalties of $5.6 million, which we recorded in "Income (loss) from disposal of discontinued operations, net of taxes," in the Consolidated Statements of Operations.

For
fiscal 2005 the loss from discontinued operations for the IBM i/p Series RAID business included the write off of acquired in process technology of $3.0 million and
amortization of intangible assets of $4.5 million. The Company also incurred $16.8 million in Research and Development costs while it generated a gross margin of $14.0 million.

Systems Business:On September 29, 2005, our Board of Directors approved management's recommendation to divest our
systems business, which includes substantially all of the operating assets and cash flows that we obtained through the Snap Appliance and Eurologic Systems acquisitions, as well as internally
developed hardware and software. In connection with this action, we classified the systems business as a discontinued operations in our consolidated financial statements and are actively pursuing a
sale of this business. In the fourth quarter of fiscal 2006 we revised our estimate of the fair values, less cost to sell and recorded a $10.0 million impairment charge on the Snap Appliance
assets.

On
January 31, 2006, we signed a definitive agreement with SanminaSCI Corporation and its wholly owned subsidiary, Sanmina-SCI USA, Inc. for the
sale of our OEM block-based systems business for $14.5 million, of which $5.0 million will be received over the next two years. In addition, Sanmina-SCI USA agreed to pay us
contingent consideration of up to an additional $12.0 million if certain revenue levels are achieved over the three-year period.. We recorded a gain of $12.1 million on the
disposal of the OEM block-based systems business in the fourth quarter of fiscal 2006.

For
fiscal 2005 the $9.5 million loss was attributed to higher product margins due in part because the acquisition of Snap Appliances. Revenues increased by $19.9 million
and gross margin increased by $18.0 million while there was only a slight increase in operating expenses of $5.1 million.

For
fiscal 2004 the systems business experienced a low gross margin on its products of 15% while there were no significant decreases in operating expenses.

Liquidity and Capital Resources

Key Components of Cash Flow

Cash used for operations was $7.1 million in fiscal 2006 and $10.3 million in fiscal 2005 compared to cash provided by operations of
$95.4 million in fiscal 2004. Cash used for operations for fiscal 2006 resulted primarily from our net loss. This was partially offset by the benefit of non-cash items included in
operating results which primarily consisted of an impairment of goodwill of $90.6 million and depreciation and amortization of intangible assets and property and equipment of
$24.5 million. Additional factors included changes to working capital assets and liabilities that decreased cash provided by operating activities by $16.3 million, of which
$21.4 million was due to a reduction in accounts payable and a decrease in inventory of $36.9 million, which was related to an overall decrease in the business and required lower
inventory amounts that in turn reduced the amounts owed to vendors,, and an increase in cash provided by operating activities of discontinued operations of $5.6 million. Cash used for
operations for fiscal 2005

resulted
primarily from our net loss. This was offset by the benefit of non-cash items included in operating results which primarily consisted of an impairment of goodwill of
$52.3 million, a decrease in our deferred tax assets of $50.7 million, depreciation and amortization of intangible assets and property and equipment of $37.2 million and
amortization of deferred stock-based compensation of $2.9 million. Additional factors included the non-cash effect on tax settlement of $26.0 million, gain on the sale of
long-lived assets of $1.4 million, a decrease in cash provided by operating activities of discontinued operations of $30.6 million, which included decreases in accrued
expenses of $16.1 million and was offset by $47.1 million related to impairment charges for other intangible assets, and changes to working capital assets and liabilities that increased
cash used for operations by $27.0 million.

Operating
cash for fiscal 2004 resulted primarily from our net income of $62.9 million, adjusted for non-cash items including depreciation and amortization of
intangible assets of $49.7 million, amortization of deferred stock-based compensation of $4.1 million, write-off of acquired in process technology of $4.0 million,
impairment loss recognized on assets held for sale of $5.0 million, write-off of minority investment of $1.0 million, loss of $6.5 million related to the repurchase of
our 3% Notes and 43/4% Notes and changes to working capital assets and liabilities that increased cash provided by operating activities by $4.6 million offset by the
non-cash portion of the gain on settlement with the former president of DPT of $18.3 million. These factors were partially offset by cash used in operating activities of
discontinued operations of $16.0 million.

used in investing activities was $287.3 million in fiscal 2006 and $22.9 million in fiscal 2004 compared to cash provided by investing activities of
$340.8 million in fiscal 2005. Cash used for investing activities in fiscal 2006 was primarily due to net sales and maturities of restricted marketable securities and marketable securities, net
of purchases, of $340.9 million and purchases of property and equipment from continuing operations of $7.1 million, partially offset by proceeds from the sale of the IBM i/p Series RAID
and Systems businesses of $33.6 million and the sale of the Singapore manufacturing assets of $26.0 million. The cash provided by investing activities in fiscal 2005 was primarily
related to sales and maturities of restricted marketable securities and marketable securities, net of purchases, of $470.6 million and proceeds from the sale of long-lived assets of
$10.9 million. This was partially offset by our use of cash for the acquisitions of Snap Appliance and the IBM i/p Series RAID business of $65.4 million, purchases of property and
equipment from continuing operations of $9.5 million and cash used in investing activities of discontinued operations of $63.4 million. The cash used in investing activities in fiscal
2004 was primarily due to our acquisitions of Eurologic, ICP vortex Computersysteme GmbH, orICP vortex, and Elipsan, payment of holdback amounts in connection with our acquisition of Platys, partially
offset by net sales and maturities of marketable securities.

Cash
used for financing activities was $14.9 million in fiscal 2006 and $110.2 million in fiscal 2004 compared to cash provided by financing activities of
$8.5 million in fiscal 2005. The cash used for financing activities in fiscal 2006 was primarily driven by the repurchase of $24.3 million in aggregate principal amount of our 3% Notes
for $24.3 million, partially offset by proceeds from our issuance of common stock in connection with the exercise of stock options. The cash provided by financing activities in fiscal 2005 was
related to net proceeds received from our issuance of common stock in connection with purchases made under our employee stock purchase plan and the exercise of stock options. The cash used in
financing activities in fiscal 2004 was primarily driven by repurchases of our 43/4% and 3% Notes, partially offset by net proceeds from the issuance of our 3/4% Notes.

Liquidity, Capital Resources and Financial Condition

At March 31, 2006, we had $556.5 million in unrestricted cash, cash equivalents and marketable securities, of which approximately
$88.2 million was held by our Singapore subsidiary. In the fourth quarter of fiscal 2005, we repatriated $360.6 million of undistributed earnings from Singapore to the United States and
incurred a tax liability of $17.6 million. The repatriated amounts will be used to fund a qualified Domestic Reinvestment Plan, as required by the American Jobs Creation Act of 2004. If we do
not spend

41

---



the
repatriated funds in accordance with our reinvestment plan, we may incur additional tax liabilities. We have not provided for U.S. deferred income taxes or foreign withholding taxes on the
remaining undistributed earnings of approximately $257.2 million since we do not have any current plans to repatriate the remaining undistributed earnings from our Singapore subsidiary to our
United States parent company. If we were to do so, additional income taxes at the combined United States Federal and state statutory rate of approximately 40% could be incurred from the repatriation.

In
December 2003, we issued $225.0 million in aggregate principal amount of our 3/4% Notes. The issuance costs associated with the 3/4% Notes
totaled $6.8 million and the net proceeds from the offering were $218.2 million. In conjunction with the issuance of the 3/4% Notes, we spent $64.1 million to enter
into a convertible bond hedge transaction. We also received $30.4 million from the issuance of warrants to purchase up to 19.2 million shares of our common stock. Please refer to
Note 6 for a detailed discussion of our debt and equity transactions. At March 31, 2006, we had $235.6 million of aggregate principal amount in convertible notes that are due in
March 2007 and December 2023 in the amount of $10.6 million and $225.0 million, respectively.

We
are required to maintain restricted cash or investments to serve as collateral for the first six scheduled interest payments and the first ten scheduled interest payments on our 3%
Notes and 3/4% Notes, respectively. As of March 31, 2006, we had $4.8 million of restricted cash and restricted marketable securities, consisting of United States
government securities, of which $1.7 million was classified as short-term and $3.1 million was classified as long-term.

We
expect capital expenditures of between $5.0 million and $10.0 million during fiscal 2007, without taking into account any acquisitions.

We
filed a petition in United States Tax Court contesting asserted deficiencies related to the IRS' audit of our fiscal 1997 tax return and final settlement agreements have been filed
with the United States Tax Court on all but one issue. In addition, the IRS is auditing our Federal income tax returns for fiscal 1998 through fiscal 2003. We have resolved all issues for fiscal 1998
through fiscal 2001 other than the rollover impact of any potential resolution on the remaining fiscal 1997 issue and tax credits that were
generated but not used in subsequent years that may be carried back. The fiscal 2002 and 2003 audit is ongoing. We believe that we have sufficient tax provisions for these years. We believe the final
outcome of the IRS audits will not have a material adverse impact on our liquidity.

The
IRS is currently auditing our income tax returns for fiscal 1997 and final settlement agreements have been filed with the United States Tax Court on all but one issue. In addition,
the IRS is auditing our Federal income tax returns for fiscal 1998 through fiscal 2001. We have resolved all issues for fiscal 1998 through fiscal 2001 other than the rollover impact of any potential

we have sufficient tax provisions for these years. We believe the final outcome of the IRS audits will not have a material adverse impact on our liquidity.

We
believe that our cash balances and the cash flows generated by operations will be sufficient to satisfy our anticipated cash needs for working capital and capital expenditures for at
least the next 12 months. However, we may require additional cash to fund acquisitions or investment opportunities. In these instances, we may seek to raise such additional funds through public
or private equity or debt financings or from other sources. We may not be able to obtain adequate or favorable financing at that time. Any equity financing we obtain may dilute existing ownership
interests and any debt financing could contain covenants that impose limitations on the conduct of our business.

We
invest in technology companies through two venture capital funds, Pacven Walden Venture V Funds and APV Technology Partners II, L.P. At March 31, 2006, the carrying value of
such investments aggregated $2.9 million. We have also committed to provide additional funding of up to $0.2 million.

Off Balance-Sheet Arrangements

In conjunction with the issuance of the 3/4% Notes in December 2003, we entered into a convertible bond hedge transaction with an affiliate
of one of the original purchasers of the 3/4% Notes. The convertible bond hedge is designed to mitigate stock dilution from conversion of the 3/4% Notes. The convertible
bond hedge has value if the average market price per share of our common stock upon exercise or expiration of the bond hedge is greater than $11.704 per share. Under the convertible bond hedge
arrangement, the counterparty agreed to sell to us up to 19.2 million shares of our common stock, which is the number of shares issuable upon conversion of the 3/4% Notes in
full, at a price of $11.704 per share. The convertible bond hedge transaction may be settled at our option either in cash or net shares and expires in December 2008. Settlement of the
convertible bond hedge in net shares on the expiration date would result in us receiving a number of shares of our common stock with a value equal to the amount otherwise receivable on cash
settlement. Should there be an early unwind of the convertible bond hedge transaction, the amount of cash or net shares potentially received by us will depend upon then-existing overall
market conditions, and on our stock price, the volatility of our stock and the amount of time remaining on the convertible bond hedge.

Critical Accounting Policies

The discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in
accordance with accounting principles generally accepted in the United States. Note 1 of the Notes to Consolidated Financial Statements describes the significant accounting policies essential
to our consolidated financial statements. The preparation of these financial statements requires estimates and assumptions that affect the reported amounts and disclosures. Although we believe that
our judgments and estimates are appropriate and correct, actual future results may differ materially from our estimates.

43

---



We
believe the following to be our critical accounting policies because they are both important to the portrayal of our financial condition and results of operations and they require
critical management judgments and estimates about matters that are uncertain. If actual results or events differ materially from those contemplated by us in making these estimates, our reported
financial condition and results of operation for future periods could be materially affected. See "Risk Factors" for certain risks relating to our future operating results.

Revenue Recognition:We recognize revenue from the majority of our product sales, including sales to OEMs, distributors and
retailers, upon shipment from us, provided that persuasive evidence of an
arrangement exists, the price is fixed or determinable and collectibility is reasonably assured. Revenue from sales where software is essential to the functionality is recognized when passage of title
and risk of ownership is transferred to customers, persuasive evidence of an arrangement exists, which is typically upon sale of product by our customer, the price is fixed or determinable and
collectibility is reasonably assured.

Our
distributor arrangements provide distributors with certain product rotation rights. Additionally, we permit our distributors to return products subject to certain conditions. We
establish allowances for expected product returns in accordance with SFAS No. 48. We also establish allowances for rebate payments under certain marketing programs entered into with
distributors. These allowances comprise our revenue reserves and are recorded as direct reductions of revenue and accounts receivable. We make estimates of future returns and rebates based primarily
on our past experience as well as the volume of products in the distributor channel, trends in distributor inventory, economic trends that might impact customer demand for our products (including the
competitive environment), the economic value of the rebates being offered and other factors. In the past, actual returns and rebates have not been significantly different from our estimates. However,
actual returns and rebates in any future period could differ from our estimates, which could impact the net revenue we report.

Inventory:The valuation of inventory requires us to estimate obsolete or excess inventory as well as inventory that is not
of salable quality. The determination of obsolete or excess inventory requires us to estimate the future demand for our products within specific time horizons, generally six to twelve months. To the
extent our demand forecast for specific products is less than quantities of our product on hand and our non-cancelable orders, we could be required to record additional inventory reserves,
which would have a negative impact on our gross margin. Additionally, if actual demand is higher than our demand forecast for specific products that have been fully reserved, our future margins may be
higher.

Goodwill:Goodwill is initially recorded when the purchase price paid for an acquisition exceeds the estimated fair value of
the net identified tangible and intangible assets acquired. We perform an annual review on the last day of February of each year, or more frequently if indicators of potential impairment exist, to
determine if the recorded goodwill is impaired. Our impairment review process compares the fair value of our segments (which we have determined to be our reporting units) to their carrying value,
including the goodwill related to the segments. To determine the fair value, our review process uses the income, or discounted cash flows approach and the market approach, which utilizes comparable
companies' data. The discounted future cash flow approach uses estimates including the following for each segment: revenue, based on assumed market growth rates and our assumed market share; estimated
costs; and appropriate discount rates based on the particular business's weighted average cost of capital. Our estimates of market segment growth, our market segment share and costs are based on
historical data, various internal estimates and certain external sources, and are based on assumptions that are consistent with the plans and estimates we are using to manage the underlying
businesses. Our business consists of both established and emerging technologies and our forecasts for emerging technologies are based upon internal estimates and external sources rather than
historical information. If future forecasts are revised, they may indicate or require future impairment charges. We also considered our market capitalization on the dates of our impairment tests under
SFAS 142, in determining the fair value of the respective

44

---



businesses.
If the carrying amount of the reporting unit, which is at our segment level, exceeds its implied fair value, goodwill is considered impaired and a second step is performed to measure the
amount of the impairment loss, if any. In fiscal 2006, we performed an assessment of the recoverability of goodwill in connection with the reorganization of our segments and determined that goodwill
was impaired. As a result, we recorded an impairment charge and wrote-off our entire balance of goodwill of $90.6 million in the second quarter of 2006. We also performed our annual
goodwill impairment test in the fourth quarter of fiscal 2005 and determined that goodwill was impaired. As a result, we recorded an impairment charge of $52.3 million in fiscal 2005 related to
our former Channel segment.

The
discounted cash flow approach for estimating the fair value is dependent on a number of factors including estimates of future market growth, forecasted revenue and costs, expected
periods the assets will be utilized and appropriate discount rates used to calculate the discounted cash flow. Our fair value estimates, as well as the allocation of net assets to reporting units, are
based on assumptions we believe to be reasonable but which are unpredictable and inherently uncertain and, as a result, actual results may differ from those estimates.

Income Taxes:We must make certain estimates and judgments in determining income tax expense for financial statement
purposes. These estimates and judgments occur in the calculation of certain tax assets and liabilities, which arise from differences in the timing of recognition of revenue and expense for tax and
financial statement purposes.

We
must assess the likelihood that we will be able to recover our deferred tax assets. We consider 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 the valuation
allowance. If recovery is not likely, we must increase our provision for taxes by recording a valuation allowance against the deferred tax assets that we estimate will not ultimately be recoverable.
As a result of our analysis of expected future income at March 31, 2005, it was considered more likely than not that a valuation allowance for all U.S. deferred tax assets was required,
resulting in a $67.9 million charge included in our tax provision. At March 31, 2006, the valuation allowance against our deferred tax assets totaled $91.5 million.

In
addition, the calculation of our tax liabilities involves dealing with uncertainties in the application of complex global tax regulations. We recognize liabilities for anticipated tax
audit issues in the U.S. and other tax jurisdictions based on our estimate of whether, and the extent to which, additional taxes and related interest will be due. If we ultimately determine that
payment of these amounts is unnecessary, we reverse the liability and recognize a tax benefit during the period in which we determine that the liability is no longer necessary. We record an additional
charge in our provision for taxes in the period in which we determine that the recorded tax liability is less than we expect the ultimate assessment to be. Tax related liabilities were released
generating a net tax benefit of $26.4 million and $6.3 million in fiscal 2005 and fiscal 2004, respectively. For a discussion of current tax matters, see Note 12 in the Notes to
Consolidated Financial Statements.

Acquisitions and Other Major Transactions

We are continually exploring strategic acquisitions to build upon our existing library of intellectual property and enhance our technological leadership in the
markets where we operate.

Fiscal 2006

Dispositions

On December 23, 2005, we entered into a three-year contract manufacturing agreement with Sanmina-SCI whereby
Sanmina-SCI, upon the closing of the transaction on January 9, 2006, assumed manufacturing operations of a majority of Adaptec products. In addition, we sold certain manufacturing
assets, buildings and improvements and inventory located in Singapore with respect to printed circuit board assemblies and storage system manufacturing operations to Sanmina-SCI for
$26.6 million (net of closing costs of $0.6 million) resulting, in a loss on disposal of assets of $1.6 million that was recorded in "Other charges (gains)" on the Consolidated
Statements of Operations.

On
September 30, 2005, we sold our IBM i/p Series RAID business to IBM for approximately $22.0 million plus $1.3 million for certain fixed assets. In addition, IBM
purchased certain related inventory at our net book value of $0.8 million. We also granted IBM a nonexclusive license to certain intellectual property and sold to IBM substantially all of the
assets dedicated to the engineering and manufacturing of RAID controllers and connectivity products for the IBM i/p Series RAID business. Under the terms of the nonexclusive license, IBM will pay us
royalties for the sale of our board-level products over the next six quarters, which will be recognized as contingent consideration in discontinued operations when earned. In fiscal 2006, we received
royalties of $5.6 million, which we recorded in "Income (loss) from disposal of discontinued operations, net of taxes," in the Consolidated Statements of Operations.

On
September 29, 2005, our Board of Directors approved management's recommendation to divest our systems business, which includes substantially all of the operating assets and
cash flows that were obtained through the Snap Appliance and Eurologic Systems acquisitions, as well as internally developed hardware and software. In connection with this action, we have classified
the systems business as a discontinued operation in our consolidated financial statements. Accordingly, we have reclassified the underlying Consolidated Statements of Operations and Consolidated
Statements of Cash Flows and related disclosures for all periods presented to reflect this business as part of discontinued operations.

On
January 31, 2006, we signed a definitive agreement with Sanmina-SCI Corporation and its wholly owned subsidiary, Sanmina-SCI USA, Inc., for the
sale of our OEM block-based systems business for $14.5 million, of which $5.0 million will be received over the next two years. In addition, Sanmina-SCI USA agreed to pay us
contingent consideration of up to an additional $12.0 million if certain revenue levels are achieved over a three-year period. We recognized a gain of $12.1 million was
recognized on the disposal of the OEM block-based systems business.

Fiscal 2005

Acquisitions

During the first quarter of fiscal 2005, we purchased the IBM i/p Series RAID business. During the second quarter of fiscal 2005, we purchased Snap Appliance.
Accordingly, the estimated fair value of assets acquired and liabilities assumed in the acquisitions and the results of operations of the acquired entities were included in our consolidated financial
statements as of the respective effective dates of the acquisitions. There were no significant differences between our accounting policies and those of the IBM i/p Series RAID business and Snap
Appliance. However, as a result of the sale of the IBM i/p Series RAID business and our plan to divest our systems business, the assets expected to be sold have been reclassified as Assets and
Liabilities of Discontinued Operations on the Consolidated Balance Sheet at March 31, 2006 and the related operations have been reclassified to "Income (loss) from discontinued operations, net
of taxes" on the Consolidated Statements of Operations, as discussed in Note 2.

IBM i/p Series RAID:On June 29, 2004, we completed the acquisition of IBM's i/p Series RAID component business line
consisting of certain purchased RAID data protection intellectual property,

46

---



semiconductor
designs and assets, and licensed from IBM related RAID intellectual property. The licensing agreement granted us the right to use IBM's RAID technology and embedded Power PC technology
for our internal and external RAID products to be sold to IBM and other customers. In conjunction with the acquisition, we also entered into a three-year exclusive product supply agreement
under which we will supply RAID software, firmware and hardware to IBM for use in IBM's iSeries and pSeries servers. We also entered into an agreement for IBM to provide silicon wafer manufacturing
processing services to us for the term of the supply agreement at agreed upon rates.

The
final purchase price totaled $49.3 million, which consists of a cash payment to IBM of $47.5 million, warrants valued at $1.1 million, net of registration costs,
and transaction costs of $0.7 million. This purchase price included a final adjustment of $0.2 million in the first quarter of fiscal 2006 to both goodwill and acquisition costs. In
connection with the acquisition, we issued to IBM a warrant to purchase 250,000 shares of our common stock at an exercise price of $8.13 per share. The warrant has a term of 5 years from the
date of issuance and is immediately exercisable. The warrant was valued using the Black-Scholes valuation model using a volatility rate of 62%, a risk-free interest rate of 3.9% and an
estimated life of 5 years. The transaction costs consisted primarily of legal, valuation and other fees.

Snap Appliance:On July 23, 2004, we completed the acquisition of Snap Appliance, a provider of NAS products, to
expand our product offerings in the external storage market and to deliver cost-effective, scalable and easy-to-use DAS, NAS, Fibre Channel and IP-based
SAN products from the workgroup to the data center. The final purchase price was $83.7 million, consisting of $76.7 million in cash and transaction fees and $7.0 million related
to the fair value of assumed stock options to purchase 1.2 million shares of our common stock. This purchase price included a final adjustment of $0.7 million in the first quarter of
fiscal 2006 to both goodwill and acquisitions costs. The assumed stock options were valued using the Black-Scholes valuation model with the following assumptions: volatility rate of 58%; a
risk-free interest rate of 2.6%; and an estimated life of 2.25 years.

Of
the total assumed stock options, stock options to purchase approximately 0.7 million shares of our common stock, with exercise prices ranging between $1.42 and $5.66 per share,
were unvested, which we refer to as the Snap Unvested Options. The Snap Unvested Options have a ten-year term and vest primarily over four years from the date of grant. The intrinsic value
of the Snap Unvested Options of $3.6 million was accounted for as deferred stock-based compensation and is being recognized as compensation expense over the related vesting periods.

In
addition, a management incentive program was established to pay former employees of Snap Appliance cash payments totaling $13.8 million, which is being paid, contingent upon
their employment with us, over a two-year period through the second quarter of fiscal 2007. Payments under the management incentive program will be expensed as employees meet their
employment obligations or are recorded as part of the Snap Appliance acquisition-related restructuring for involuntarily terminations by us. In fiscal 2005, the Consolidated Statements of Operations
included compensation expense related to the management incentive program of $5.7 million and an additional $1.4 million was originally accrued in the Snap Appliance acquisition-related
restructuring. Any amounts outstanding as of the completion of the sale of the systems business, which includes Snap Applicance, will be accelerated.

A
portion of the Snap Appliance acquisition price totaling $5.4 million was held back, and in connection with the management incentive program, $1.3 million will be held
back for a total of $6.7 million, also referred to as the Snap Appliance Holdback, for unknown liabilities that may have existed as of the acquisition date. The Snap Appliance Holdback was to
be paid in the second quarter of fiscal 2006, except for funds necessary to provide for any pending claims: we have asserted claims against the holdback totaling approximately $3.0 million.

Acquisition-Related Restructuring:During the first quarter of fiscal 2006, we finalized our Snap
Appliance integration plan to eliminate certain duplicative resources, including severance and benefits in connection with the involuntary termination of approximately 24 employees, exiting
duplicative facilities

47

---



and
disposing of duplicative assets. The acquisition-related restructuring liabilities were accounted for under EITF No. 95-3 and therefore were included in the purchase price
allocation. We recorded a total liability of $6.7 million for these activities, of which the original estimate of $6.0 million was recorded in the second quarter of fiscal 2005 and total
adjustments of $0.7 million were recorded in each subsequent quarter through the first quarter of fiscal 2006. Any further changes to our finalized plan will be accounted for under SFAS
No. 146 and will be recorded in "Discontinued operations, net of taxes" in the Consolidated Statements of Operations. In the third quarter of fiscal 2006, we recorded additional adjustments of
$0.2 million due to additional lease costs related to the estimated loss of facilities that we subleased. As of March 31, 2006, we had utilized $4.4 million of these charges. We
anticipate that the remaining restructuring reserve balance of $2.5 million will be paid out by the third quarter of fiscal 2012, primarily related to long-term facility leases.

IBM Distribution Agreement

In December 2004, we entered into a distribution agreement with IBM for our RAID controllers and connectivity products sold for IBM's iSeries and pSeries
servers. The agreement was made through an amendment to our existing i/p Series RAID supply and intellectual property agreement entered into in June 2004 (See Note 17). The distribution
agreement was accounted for as a standalone transaction as it was not contemplated at the time we entered into the original IBM i/p Series RAID transaction.

On
September 30, 2005, we sold the IBM i/p Series RAID business to IBM. As a result the distribution agreement was cancelled as part of the sale.

Fiscal 2004

Acquisitions

During the first quarter of fiscal 2004, we purchased Eurologic and ICP vortex. During the fourth quarter of fiscal 2004, we purchased Elipsan. Accordingly, the
estimated fair value of assets acquired and liabilities assumed in the acquisitions and the results of operations of the acquired entities were included in our consolidated financial statements as of
the respective effective dates of the acquisitions. There were no significant differences between our accounting policies and those of Eurologic, ICP vortex or Elipsan. However, as a result of our
plan to divest the systems business, which includes Eurologic, the assets expected to be sold have been reclassified as Assets and Liabilities of Discontinued Operations on the Consolidated Balance
Sheet at March 31, 2006 and the related operations have been reclassified to "Income (loss) from discontinued operations, net of taxes" on the Consolidated Statements of Operations, as
discussed in Note 2.

Eurologic:On April 2, 2003, we completed the acquisition of Eurologic, a provider of external and networked storage
products. We acquired Eurologic to further enhance our direct-attached and fibre-attached server storage capabilities by allowing us to provide end-to-end block- and
file-based networked storage products. As consideration for the acquisition of all of the outstanding capital stock of Eurologic, we paid $25.6 million in cash, subject to a
Holdback as described below, and assumed stock options to purchase 0.5 million shares of our common stock, with a fair value of $1.6 million. We also incurred $1.1 million in
transaction fees, including legal, valuation and accounting fees. The assumed stock options were valued using the Black-Scholes valuation model with the following assumptions: volatility rate ranging
from 57% to 81%; a risk-free interest rate ranging from 1.1% to 2.5%; and an estimated life ranging from 0.08 to 4 years.

Eurologic Holdback:As part of the Eurologic purchase agreement, $3.8 million of the cash
payment was held back, also known as the Holdback, for unknown liabilities that may have existed as of the acquisition date. The Holdback, which was included as part of the purchase price, was
included in "Accrued liabilities" in the Consolidated Balance Sheet as of March 31, 2005 and was to be paid to the former Eurologic stockholders 18 months after the acquisition closing
date, except for funds necessary to

48

---



provide
for any pending claims. We paid $2.3 million of the Holdback as of March 31, 2005 and have asserted claims against the remaining amount for liabilities of which we became aware
following the consummation of the transaction. The former Eurologic stockholders have disputed these claims and have requested release of the remaining Holdback.

Eurologic Earn-out Payments:We also agreed to pay the stockholders of Eurologic
contingent consideration of up to $10.0 million in cash if certain revenue levels were achieved by the acquired Eurologic business in the period from July 1, 2003 through June 30,
2004. The milestone to achieve the contingent consideration was not attained as of June 30, 2004. As a result, no additional payments were made to former stockholders of Eurologic.

Eurologic Acquisition-Related Restructuring:During the fourth quarter of fiscal 2004, we finalized
our plans to integrate the Eurologic operations. The integration plan included the involuntary termination or relocation of approximately 110 employees, exiting duplicative facilities and the
transition of all manufacturing operations from Dublin, Ireland to our manufacturing facility in Singapore. The consolidation of the manufacturing operations as well as involuntary employee
terminations was completed in the fourth quarter of fiscal 2004. The acquisition-related restructuring liabilities were accounted for under EITF No. 95-3 and therefore were included
in the purchase price allocation of the cost to acquire Eurologic. We recorded a liability of $3.3 million in fiscal 2004 for these activities. As of December 31, 2004, we utilized all
of these charges and the plan is materially complete.

ICP vortex:On June 5, 2003, we completed the acquisition of ICP vortex. ICP vortex was a wholly-owned subsidiary of
Intel Corporation and provided a broad range of hardware and software RAID data protection products, including SCSI, SATA and fibre channel products. The final purchase price was $14.5 million
in cash, which included $0.3 million in transaction fees, consisting of legal, valuation and accounting fees. This purchase price included a final adjustment of $0.1 million in the first
quarter of fiscal 2005 to both goodwill and acquisitions costs.

During
the first quarter of fiscal 2005, we finalized our plans to integrate the ICP vortex operations. The integration plan included the involuntary termination of 19 employees, the
transfer of manufacturing operations to Singapore and the integration of certain duplicative resources. The acquisition-related restructuring liabilities were accounted for under EITF
No. 95-3 and therefore were included in the purchase price allocation of the cost to acquire ICP vortex. In fiscal 2004, we recorded a liability of $0.4 million for severance
and benefits, of which $0.3 million of these charges were utilized and $0.1 million was recorded as a reduction to the restructuring liability with a corresponding decrease to goodwill
in the first quarter of fiscal 2005.

Elipsan:On February 13, 2004, we completed the acquisition of Elipsan, a provider of networked storage infrastructure
software. Elipsan's storage virtualization technology was acquired to enable us to make storage more cost-effective, easier to scale, and to increase performance across multiple RAID
subsystems. The final purchase price was $19.4 million in cash, which included $0.7 million in transaction fees, consisting of legal, valuation and accounting fees. The purchase price
included a final adjustment of $0.8 million in fiscal 2005, primarily related to the reversal of the acquisition-related restructuring reserves of approximately $0.7 million.

Elipsan Holdback:As part of the Elipsan purchase agreement, $2.0 million of the cash payment
was held back, also known as the Elipsan Holdback, for unknown liabilities that may have existed as of the acquisition date. The Elipsan Holdback of $2.0 million was paid in the second quarter
of fiscal 2006.

Elipsan Acquisition-Related Restructuring:During the fourth quarter of fiscal 2005, we finalized our
plans related to the integration of the Elipsan operations. The plan included the integration of certain duplicative resources, related to both severance and benefits in connection with the
involuntary termination or relocation of employees and, accordingly, recorded a $0.8 million reserve as of March 31,

2004.
In fiscal 2005, we recorded an adjustment of $0.7 million as a reduction to the liability with a corresponding decrease to goodwill, as we intend to retain these employees. The
acquisition-related restructuring liabilities were accounted for under EITF No. 95-3 and therefore were included in the purchase price allocation of the cost to acquire Elipsan. As
of March 31, 2005, we made payments of approximately $25,000 under the plan. We anticipate that the remaining restructuring reserve balance of approximately $45,000 will be paid out by the
second quarter of fiscal 2007.

Recent Accounting Pronouncements

In June 2005, the FASB issued SFAS No. 154, which changes the requirements for the accounting for, and reporting of, a change in accounting
principle. Previously, most voluntary changes in accounting principles were required to be recognized by way of a cumulative effect adjustment within net income during the period of the change. SFAS
No. 154 requires retrospective application to prior periods' financial statements, unless it is impracticable to determine either the period-specific effects or the cumulative effect of the
change. SFAS No. 154 is effective for accounting changes made in fiscal years beginning after December 15, 2005; however, the statement does not change the transition provisions of any
existing accounting pronouncements. Our results of operations and financial condition will only be impacted following the adoption of SFAS No. 154 if we implement changes in accounting
principles that are addressed by the standard or correct accounting errors in future periods.

In
December 2004, the FASB issued SFAS No. 123(R). This statement replaces SFAS No. 123, amends SFAS No. 95 and supersedes APB Opinion No. 25. SFAS
No. 123(R) requires companies to apply a fair-value based measurement method in accounting for share-based payment transactions with employees and to record compensation expense for
all stock awards granted and to awards modified, repurchased or cancelled after the required effective date. In addition, we are required to record compensation expense (as previous awards continue to
vest) for the unvested portion of previously granted awards that remain outstanding at the date of adoption. In April 2005, the SEC approved that SFAS No. 123(R) will be effective for
annual periods, as opposed to interim periods as originally issued by the FASB, beginning after June 15, 2005. In March 2005, the SEC issued SAB 107, which offers guidance on SFAS
No. 123(R). SAB 107 was issued to assist preparers by simplifying some of the implementation challenges of SFAS No. 123(R) while enhancing the information that investors receive. We
intend to use the modified prospective method, which will result in a significant increase to expenses on our consolidated financial statements beginning April 1, 2006. We cannot currently
quantify the impact of the adoption of SFAS No. 123(R) and SAB 107 as it will depend on the amount of share-based payments that we grant in the future as well as other variables that
affect the fair market value estimates which cannot be forecasted at this time. The pro forma disclosures of the impact of SFAS
No. 123 provided in Note 1 of the Notes to the Consolidated Financial Statements may not be representative of the impact of adopting this statement.

In
June 2005, the FASB issued FSP 143-1, which provides guidance in accounting for obligations associated with Directive 2002/96/EC (the "Directive") on Waste
Electrical and Electronic Equipment adopted by the European Union. FSP 143-1 is required to be applied to the later of the first period ending after June 6, 2005 or the date
of the Directive's adoption into law by the applicable EU member countries in which we have significant operations. The Directive distinguishes between "new" and "historical" waste. New waste relates
to products put on the market after August 13, 2005. FSP 143-1 directs commercial users to apply the provisions of SFAS No. 143 and the related FIN No. 47 for
the measurement and recognition of the liability and asset retirement obligation associated with the historical waste management requirements of the Directive. Additonally,
FSP 143-1 provides guidance for the accounting by producers for the financing of the obligations of historical waste held by private households. We expect to adopt
FSP 143-1 in fiscal 2007. We are continuing to analyze the impact of the Directive and FSP 143-1 on our financial position and results of operations.

In
November 2005, the FASB issued FSP 115-1 and FAS 124-1, which clarifies when an investment is considered impaired, whether the impairment
is other than temporary, and the measurement of an

50

---



impairment
loss. It also includes accounting considerations subsequent to the recognition of an other-than-temporary impairment and requires certaindisclosures about unrealized
losses that have not been recognized as other-than-temporary impairments. FSP 115-1 and FAS 124-1 are effective for all reporting periods
beginning after December 15, 2005. At March 31, 2006, none of our unrealized investment losses were recognized as other-than-temporary impairments in our
available-for-securities. We do not believe FSP 115-1 and FAS 124-1 will have a material effect on our consolidated financial position,
results of operations or cash flow.

In
November 2004, the FASB issued SFAS No. 151, which clarifies the accounting for abnormal amounts of facility expense, freight, handling costs and wasted materials
(spoilage) to require them to be recognized as current-period charges. This statement is effective for inventory costs incurred during fiscal years beginning after June 15, 2005. Earlier
application is permitted. The adoption of this standard is not expected to have a material impact on our financial statements.

Item 7A.Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk

Our exposure to market risk for a change in interest rates relates primarily to our investment portfolio. As of March 31, 2006, our
available-for-sale debt investments, excluding those classified as cash equivalents, totaled $430.0 million (see Note 3 of the Notes to Consolidated Financial
Statements) and included corporate obligations, commercial paper, other debt securities, municipal bonds and United States government securities, all of which are of high investment grade. They are
subject to interest rate risk and will decline in value if market interest rates increase. If market interest rates were to increase immediately and uniformly by 10% from levels as of March 31,
2006, the decline in the fair value of the portfolio would not be material to our financial position. Declines in interest rates will, over time, reduce our interest income.

Equity Price Risk

We consider our direct exposure to equity price risk to be minimal. We invest in technology companies through two venture capital funds. As of March 31,
2006, the carrying value of such investments aggregated $2.9 million. We monitor our equity investments on a periodic basis. In the event that the carrying value of our equity investments
exceeds their fair value, and the decline in value is determined to be other-than-temporary, the carrying value is reduced to its current fair value.

Foreign Currency Risk

We translate foreign currencies into U.S dollars for reporting purposes; currency fluctuations can have an impact on our results. For all three fiscal years
presented there was an immaterial currency exchange impact from our intercompany transactions. In the past, we have entered into forward exchange contracts to hedge certain firm commitments
denominated into foreign currencies. Forward exchange contracts are denominated in the same currency as the underlying transaction and the terms of the forward foreign exchange contracts generally
match the terms of the underlying transactions. The amount of local currency obligations settled in any period is not significant to our cash flows or results of operations, although we continuously
monitor the amount and timing of those obligations. As there
were no forward exchange contracts outstanding as of March 31, 2006 and 2005, the effect of an immediate 10% change in exchange rates on forward exchange contracts would not have affected our
financial position or results of operations.

Item 9.Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

None.

Item 9A.Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our Chief Executive Officer (CEO) and our Chief Financial Officer (CFO), we
conducted an evaluation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (Exchange Act),
as of the end of the period covered by this Annual Report on Form 10-K. Based upon that evaluation, our CEO and our CFO have concluded that the design and operation of our
disclosure controls and procedures were effective to
ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act (i) is recorded, processed, summarized and reported within the time periods
specified in Securities and Exchange Commission rules and forms and (ii) is accumulated and communicated to our management, including our CEO and CFO, as appropriate to allow timely decisions
regarding required disclosure.

Management's Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control over financial reporting
was designed to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements for external purposes in accordance with generally
accepted accounting principles. 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 the assets of the company; (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 receipts and expenditures of the company are being made only in accordance with authorizations of
management and directors of the company; and (iii) 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.

Management
assessed the effectiveness of our internal control over financial reporting as of March 31, 2006, the end of our fiscal year. Management based its assessment on
criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Management's assessment included evaluation of
such elements as the design and operating effectiveness of financial reporting controls, process documentation, accounting policies, and our overall control environment. We reviewed the results of
management's assessment with the Audit Committee of our Board of Directors.

Based
on our assessment, management has concluded that our internal control over financial reporting was effective as of March 31, 2006.

Our
assessment of the effectiveness of our internal control over financial reporting as of March 31, 2006, has been audited by PricewaterhouseCoopers LLP, our independent
registered public accounting firm, as stated in their report which is included herein.

Inherent Limitations on Effectiveness of Controls

Our management, including the CEO and CFO, does not expect that our disclosure controls and procedures or our internal control over financial reporting will
prevent or detect all error and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system's objectives will be
met. The design of a control system must reflect the

52

---



fact
that there are resource constraints, and the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of
controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the company have been detected. These
inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the
individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the
likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of any evaluation of controls
effectiveness to future periods are subject to risks. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or
procedures.

ADAPTEC, INC.        NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Summary of Significant Accounting Policies

Description

Adaptec, Inc. ("Adaptec" or the "Company") designs, manufactures and markets storage products and software that are easy to manage and enable organizations
to move, manage and protect critical data and digital content. The Company's software and hardware products range from ASIC and RAID components to external storage arrays, and span SCSI, Serial
Attached SCSI, SATA, Fibre Channel, and iSCSI technologies. Adaptec's broad range of chips, add-in cards and network storage arrays gives businesses a migration path from internal to
external storage. Adaptec's products use a common management tool to simplify storage administration and reduce related costs. Adaptec products are sold through OEMs and distribution channel
customers to enterprises, small and midsize businesses, government agencies, VARs, direct marketers, and retail users across geographically diverse markets.

Basis of Presentation

The consolidated financial statements include the accounts of Adaptec and all of its wholly-owned subsidiaries after elimination of intercompany transactions and
balances.

The
glossary of key acronyms used in the Company's industry and accounting rules and regulations referred to within the Notes are listed in alphabetical order in Note 20.

Use of Estimates and Reclassifications

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make
estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The Company relies on forward looking projections to estimate any potential
valuation allowances required related to net deferred tax assets, inventory reserves or impairments of long-lived assets. These estimates include, among other things, the amount and timing
of future revenues that are expected to come from products and services that have either recently been introduced or that are to be introduced in the future. It is reasonably possible that actual
results could differ from such estimates resulting in valuation allowances of net deferred tax assets, inventory reserve charges, goodwill impairments or other charges.

Certain
reclassifications have been made to prior period reported amounts to conform to the current year presentation, including reclassification of auction rate securities from cash and
cash equivalents to marketable securities. Previously, such auction rate securities were classified as cash and cash equivalents. Accordingly, the Company revised its presentation to exclude from cash
and cash equivalents $16.7 million of auction rate securities at March 31, 2004, and to include such amounts as marketable securities. In addition, the Company has made corresponding
adjustments to the accompanying consolidated statements of cash flows to reflect the gross purchases and sales of these auction rate securities as investing activities. This reclassification resulted
in a net decrease in cash used for investing activities by $6.5 million in fiscal 2004. This reclassification had no impact on previously reported results of operations, cash flows from
operating activities or working capital of the Company.

In
addition, as discussed in Note 2, on September 30, 2005, the Company completed the sale to International Business Machines ("IBM") of its IBM i/p Series RAID component
business ("IBM i/p Series RAID Business"), and on September 29, 2005 the Company's Board of Directors approved management's recommendation to divest its systems business, which includes
substantially all of the operating assets and cash flows that were obtained through the Company's acquisition of Snap Appliance,

Inc.
in fiscal 2005 and Eurologic Systems Group Limited in fiscal 2004 as well as internally generated hardware and software. Both of these businesses have been accounted for as discontinued
operations. Accordingly, the Company has reclassified the underlying Consolidated Statements of Operations and Consolidated Statements of Cash Flows and related disclosures for all periods presented
to reflect the IBM i/p Series RAID Business and the systems business as discontinued operations. In the third quarter of fiscal 2006, in conjunction with the renegotiation of a customer supply
contract, the Company decided to retain a product line that was previously classified within discontinued systems business. Accordingly, the Company has reclassified the underlying Consolidated
Statements of Operations and Consolidated Statements of Cash Flows and related disclosures for all periods presented to reflect that product line as part of continuing operations.

Unless
otherwise indicated and other than balance sheet amounts as of March 31, 2005, the Notes to the Consolidated Financial Statements relate to the discussion of the Company's
continuing operations.

Acquisitions

In fiscal 2005, the Company purchased the IBM i/p Series RAID business and Snap Appliance, Inc. ("Snap Appliance"). In fiscal 2004, the Company purchased
Eurologic Systems Group Limited ("Eurologic"), ICP vortex Computersysteme GmbH ("ICP vortex") and Elipsan Limited ("Elipsan"). Accordingly, the estimated fair value of assets acquired and liabilities
assumed in the acquisitions and the results of operations of the acquired entities were included in the Company's consolidated financial statements as of the respective effective dates of the
acquisitions. There were no significant differences between the Company's accounting policies and those of the IBM i/p Series RAID business, Snap Appliance, Eurologic, ICP vortex or Elipsan. See
Note 17 for further discussion of the Company's acquisition activities. However, as a result of the sale of the IBM i/p Series RAID Business and the Company's plan to divest its systems
business, the assets expected to be sold have been classified as Assets and Liabilities of Discontinued Operations on the Consolidated Balance Sheet at March 31, 2006 and the related operations
have been reclassified to "Income (loss) from discontinued operations, net of taxes" on the Consolidated Statements of Operations, as discussed in Note 2. This reclassification is primarily
related to the IBM i/p Series RAID Business, Snap Appliance and Eurologic acquisitions.

Foreign Currency Translation

For foreign subsidiaries whose functional currency is the local currency, the Company translates assets and liabilities to United States dollars using
period-end exchange rates, and translates revenues and expenses using average monthly exchange rates. The resulting cumulative translation adjustments are included in "Accumulated other
comprehensive income, net of taxes," a separate component of stockholders' equity in the Consolidated Balance Sheets.

For
foreign subsidiaries whose functional currency is the United States dollar, certain assets and liabilities are remeasured at the period-end or historical rates as
appropriate. Revenues and expenses are remeasured at the average monthly rates. Currency transaction gains and losses are recognized in current operations and have not been material to the Company's
operating results for the periods presented.

Derivative Financial Instruments

The Company did not enter into forward exchange or other derivative foreign currency contracts during the fiscal years ended March 31, 2006, 2005 and 2004.
The Company does not hold or issue foreign

exchange
contracts for trading or speculative purposes. In connection with the issuance of its 3/4% Convertible Senior Subordinated Notes due 2023 ("3/4% Notes"), the
Company entered into a derivative financial instrument to repurchase its common stock, at the Company's option, at specified prices in the future to mitigate potential dilution as a result of the
conversion of the 3/4% Notes. See Note 6 for further details.

Fair Value of Financial Instruments

For certain of the Company's financial instruments, including accounts receivable and accounts payable, the carrying amounts approximate fair value due to their
short maturities. The following table represents the related cost basis and the estimated fair values, which are based on quoted market prices, for the Company's publicly traded debt:

Cash Equivalents and Marketable Securities

Cash equivalents consist of highly liquid investments with remaining maturities of three months or less at the date of purchase. Marketable securities consist of
corporate obligations, commercial paper, other debt securities, municipal bonds and United States government securities with remaining maturities beyond three months. The Company's policy is to
protect the value of its investment portfolio and minimize principal risk by earning returns based on current interest rates.

Marketable
securities, including equity securities, are classified as available-for-sale and are reported at fair market value and unrealized gains and losses,
net of income taxes are included in "Accumulated other comprehensive income, net of taxes" as a separate component of stockholders' equity in the Consolidated Balance Sheets. The marketable securities
are adjusted for amortization of premiums and discounts and such amortization is included in "Interest and other income" in the Consolidated Statements of Operations. When the fair value of an
investment declines below its original cost, the Company considers all available evidence to evaluate whether the decline in value is other-than-temporary. Among
other things, the Company considers the duration and extent to which the market value has declined relative to its cost basis and economic factors influencing the markets. Unrealized losses considered
other-than-temporary are charged to "Interest and other income" in the Consolidated Statements of Operations in the period in which the determination is made. Gains and losses
on securities sold are determined based on the average cost method and are included in "Interest and other income" in the Consolidated Statements of Operations. The Company does not hold its
securities for trading or speculative purposes.

Restricted
marketable securities consist of United States government securities that are required as security under both the indenture related to the 3% Notes and the indenture related
to the 3/4% Notes (Note 6).

Concentration of Risk

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash, cash equivalents, marketable
securities and trade accounts receivable. The Company invests in high-credit quality investments, maintained with major financial institutions. The Company, by policy, limits the amount of
credit exposure through diversification and management regularly monitors the composition of its investment portfolio for compliance with the Company's investment policies.

The
Company sells its products to OEMs, distributors and retailers throughout the world. Sales to customers are predominantly denominated in United States dollars and, as a result, the
Company believes its foreign currency risk is minimal. The Company performs ongoing credit evaluations of its customers' financial condition and generally does not require collateral from its
customers. The Company maintains an allowance for doubtful accounts based upon the expected collectibility of all accounts receivable.

Two
customers accounted for 28% and 18% of gross accounts receivable at March 31, 2006. Two customers accounted for 14% and 11% of gross accounts receivable at March 31,
2005. In fiscal 2006, IBM and Dell accounted for 30% and 16% of total revenues, respectively. In fiscal 2005, IBM and Dell accounted for 24% and 15% of total revenues, respectively. In fiscal 2004,
IBM and Dell accounted for 21% and 12% of total revenues, respectively.

The
Company currently purchases the majority of its finished products from Sanmina-SCI and if Sanmina- SCI fails to meet the Company's manufacturing needs, it would delay
product shipments to the Company's customers.

The
Company's industry is characterized by rapid technological change, competitive pricing pressures and cyclical market patterns. The Company's financial results are affected by a wide
variety of factors, including general economic conditions worldwide, economic conditions specific to its industry, the timely implementation of new manufacturing technologies and the ability to
safeguard patents and intellectual property in a rapidly evolving market. In addition, the market for its products has historically been cyclical and subject to significant economic downturns at
various times. As a result, the Company may experience significant period-to-period fluctuations in future operating results due to the factors mentioned above or other
factors. The Company believes that its existing sources of liquidity, including its cash, cash equivalents and investments, will be adequate to support its operating and capital investment activities
for the next twelve months.

Inventories

Inventories are stated at the lower of cost or market, with cost determined on a first-in, first-out basis. The Company writes down
inventories based on estimated excess and obsolete inventories determined primarily by future demand forecasts. At the point of loss recognition, a new, lower cost basis for that inventory is
established, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis.

Property and Equipment

Property and equipment are stated at cost and depreciated or amortized using the straight-line method over the estimated useful lives of the assets.
The Company capitalizes substantially all costs related to the purchase and implementation of software projects used for internal business operations. Capitalized

F-8

---



internal-use
software costs primarily include license fees, consulting fees and any associated direct labor costs and are amortized over the estimated useful life of the asset, typically a
three to five-year period.

Goodwill and Other Intangible Assets

Goodwill represents the excess of the purchase price paid over the fair value of tangible and identifiable intangible net assets acquired in business
combinations. Goodwill is reviewed annually and whenever events or circumstances occur which indicate that goodwill might be impaired. Other intangible assets, net, consist of acquisition-related
intangible assets, intellectual property and warrants. Other intangible assets, net, are carried at cost less accumulated amortization. Other intangible assets are amortized over their estimated
useful lives ranging from three months to seven years, reflecting the pattern in which the economic benefits of the assets are expected to be realized.

Impairment of Long-Lived Assets

In accordance with SFAS No. 144, the Company regularly performs reviews to determine if facts or circumstances are present, either internal or external,
which would indicate if the carrying values of its long-lived assets are impaired. When the Company determines that the carrying value of its long-lived assets, other than
goodwill, may not be recoverable based upon the existence of one or more indicators of impairment, the Company measures any impairment based on a discounted estimated future cash flows method and
applying a discount rate commensurate with the risks inherent in its current business model. The impairment of long-lived assets is included in "Other charges (gains)" in the Consolidated
Statements of Operations. In fiscal 2004, the Company recorded a $5.0 million charge for impairment of properties classified as assets held for sale as the carrying amount exceeded its
estimated fair value less cost to sell (Note 10). In fiscal 2005, the Company recorded a gain on the sale of these properties of $2.8 million and was credited to "Other charges (gains)"
in the Consolidated Statements of Operations. In 2006, the Company recorded a loss of $1.6 million on sale of its Singapore manufacturing operations in "Other charges (gains)" in the
Consolidated Statement of Operations.

Stock-Based Compensation

The Company has employee and director stock compensation plans which are more fully described in Note 7. The Company accounts for stock-based compensation
in accordance with APB Opinion No. 25 as interpreted by FIN 44, and complies with the disclosure provisions of SFAS No. 148, an amendment of SFAS No. 123. Under APB Opinion
No. 25, compensation expense is recognized on the measurement date based on the excess, if any, of the fair value of the Company's common stock over the amount an employee must pay to acquire
the common stock.

The
Company accounts for equity instruments issued to non-employees in accordance with the provisions of SFAS No. 123 and EITF No. 96-18, which
requires that such equity
instruments be recorded at their fair value on the measurement date, which is typically the date of grant.

The
following table illustrates the effect on net income (loss) and net income (loss) per share if the Company had applied the fair value recognition provisions of SFAS No. 123 to
employee and director

Revenue Recognition

The Company recognizes revenue from the majority of its product sales, including sales to OEMs, distributors and retailers, upon shipment from the Company,
provided that persuasive evidence of an arrangement exists, the price is fixed or determinable and collectibility is reasonably assured. Revenue from sales where software is essential to the
functionality, is recognized when passage of title and risk of ownership is transferred to customers, persuasive evidence of an arrangement exists, which is typically upon sale of product by the
customer, the price is fixed or determinable and collectibility is reasonably assured.

The
Company's distributor arrangements provide distributors with certain product rotation rights. Additionally, the Company permits distributors to return products subject to certain
conditions. The Company establishes allowances for expected product returns in accordance with SFAS No. 48. The Company also establishes allowances for rebate payments under certain marketing
programs entered into with distributors. These allowances comprise the Company's revenue reserves and are recorded as direct reductions of revenue and accounts receivable. The Company makes estimates
of future returns and rebates based primarily on its past experience as well as the volume of products in the distributor channel, trends in distributor inventory, economic trends that might impact
customer demand for its products (including the competitive environment), the economic value of the rebates being offered and other factors. In the past, actual returns and rebates have not been
significantly different from the Company's estimates. However, actual returns and rebates in any future period could differ from the Company's estimates, which could impact the net revenue it reports.

For
products which contain software, where software is essential to the functionality of the product, or software product sales, the Company recognizes revenue in accordance with SOP
No. 97-2, as amended and modified by SOP 98-9. For software sales that are considered multiple element transactions, the entire

F-10

---



fee
from the arrangement is allocated to each respective element based on its vendor specific fair value or upon the residual method and recognized when revenue recognition criteria for each element
are met. Vendor specific fair value for each element is established based on the sales price charged when the same element is sold separately or based upon a renewal rate.

Software Development Costs

The Company's policy is to capitalize software development costs incurred after technological feasibility has been demonstrated, which is determined to be the
time a working model has been completed. Through March 31, 2006, costs incurred subsequent to the establishment of technological feasibility have not been significant and all software
development costs have been charged to "Research and development" in the Consolidated Statements of Operations.

Income Taxes

The Company accounts for income taxes using an asset and liability approach, which requires recognition of deferred tax assets and liabilities for the expected
future tax consequences of events that have been recognized in the Company's consolidated financial statements, but have not been reflected in the Company's taxable income. A valuation allowance is
established to reduce deferred tax assets to their estimated realizable value. The Company provides a valuation allowance to the extent that the Company does not believe it is more likely than not
that it will generate sufficient taxable income in future periods to realize the benefit of its deferred tax assets. Predicting future taxable income is difficult, and requires the use of significant
judgment.

Recent Accounting Pronouncements

In June 2005, the FASB issued SFAS No. 154, which changes the requirements for the accounting for, and reporting of, a change in accounting
principle. Previously, most voluntary changes in accounting principles were required to be recognized by way of a cumulative effect adjustment within net income during the period of the change. SFAS
No. 154 requires retrospective application to prior periods'
financial statements, unless it is impracticable to determine either the period-specific effects or the cumulative effect of the change. SFAS No. 154 is effective for accounting changes made in
fiscal years beginning after December 15, 2005; however, the Statement does not change the transition provisions of any existing accounting pronouncements. The Company's results of operations
and financial condition will only be impacted following the adoption of SFAS No. 154 if it implements changes in accounting principles that are addressed by the standard or corrects accounting
errors in future periods.

In
December 2004, the FASB issued SFAS No. 123(R). This statement replaces SFAS No. 123, amends SFAS No. 95 and supersedes APB Opinion No. 25. SFAS
No. 123(R) requires companies to apply a fair-value based measurement method in accounting for share-based payment transactions with employees and to record compensation expense for
all stock awards granted and to awards modified, repurchased or cancelled after the required effective date. In addition, the Company is required to record compensation expense (as previous awards
continue to vest) for the unvested portion of previously granted awards that remain outstanding at the date of adoption. In April 2005, the SEC approved that SFAS No. 123(R) will be
effective for annual periods, as opposed to interim periods as originally issued by the FASB, beginning after June 15, 2005. In March 2005, the SEC issued SAB 107, which offers guidance
on SFAS No. 123(R). SAB 107 was issued to assist preparers by simplifying some of the implementation

F-11

challenges
of SFAS No. 123(R) while enhancing the information that investors receive. The Company intends to use the modified prospective method, which will result in a significant increase to
expenses on the Company's consolidated financial statements beginning April 1, 2006. The Company cannot currently quantify the impact of the adoption of SFAS No. 123(R) and SAB 107 as it
will depend on the amount of share-based payments that the Company grants in the future as well as other variables that affect the fair market value estimates which cannot be forecasted at this time.
The pro forma disclosures of the impact of SFAS No. 123 provided in Note 1 may not be representative of the impact of adopting this statement.

In
June 2005, the FASB issued FSP 143-1, which provides guidance in accounting for obligations associated with Directive 2002/96/EC (the "Directive") on Waste
Electrical and Electronic Equipment adopted by the European Union. FSP 143-1 is required to be applied to the later of the first period ending after June 6, 2005 or the date
of the Directive's adoption into law by the applicable EU member countries in which we have significant operations. The Directive distinguishes between "new" and "historical" waste. New waste relates
to products put on the market after August 13, 2005. FSP 143-1 directs commercial users to apply the provisions of SFAS No. 143 and the related FIN No. 47 for
the measurement and recognition of the liability and asset retirement obligation associated with the historical waste management requirements of the Directive. Additionally,
FSP 143-1 provides guidance for the accounting by producers for the financing of the obligations of historical waste held by private households. We expect to adopt
FSP 143-1 in fiscal 2007. We are continuing to analyze the impact of the Directive and FSP 143-1 on our financial position and results of operations.

In
November 2005, the FASB issued FSP 115-1 and FAS 124-1, which clarifies when an investment is considered impaired, whether the impairment
is other than temporary,
and the measurement of an impairment loss. It also includes accounting considerations subsequent to the recognition of an other-than-temporary impairment and requires certain
disclosures about unrealized losses that have not been recognized as other-than-temporary impairments. FSP 115-1 and FAS 124-1 are
effective for all reporting periods beginning after December 15, 2005. At March 31, 2006, none of our unrealized investment losses were recognized as
other-than-temporary impairments in our available-for-securities. We do not believe FSP 115-1 and FAS 124-1 will
have a material effect on our consolidated financial position, results of operations or cash flow.

In
November 2004, the FASB issued SFAS No. 151, which clarifies the accounting for abnormal amounts of facility expense, freight, handling costs and wasted materials
(spoilage) to require them to be recognized as current-period charges. This statement is effective for inventory costs incurred during fiscal years beginning after June 15, 2005. Earlier
application is permitted. The adoption of this standard is not expected to have a material impact on the Company's financial statements.

Note 2. Discontinued Operations



On September 30, 2005, the Company entered into a series of arrangements with IBM pursuant to which the Company sold its IBM i/p Series RAID Business to
IBM for approximately $22.0 million plus $1.3 million for certain fixed assets. In addition, IBM purchased certain related inventory at the Company's net book value of
$0.8 million. Expenses incurred in the transaction primarily included costs of approximately $0.5 million for legal and accounting fees. In addition, the Company accrued
$0.3 million for lease obligations. Under the terms of the agreements, the Company granted IBM a nonexclusive license to certain intellectual property and sold to IBM substantially all of the
assets dedicated to the

engineering
and manufacturing of RAID controllers and connectivity products for the IBM i/p Series RAID Business. Under the terms of the nonexclusive license, IBM will pay royalties to the Company for
the sale of its board-level products over the next six quarters, which will be recognized as contingent consideration in discontinued operations when earned. In fiscal 2006, the Company received
royalties of $5.6 million, which the Company recorded in "Income (loss) from disposal of discontinued operations, net of taxes," in the Consolidated Statements of Operations. Through
March 31, 2006, the Company had incurred a loss of $2.3 million on the disposal of the IBM i/p Series RAID Business.

Systems Business:

On September 29, 2005, the Company's Board of Directors approved management's recommendation to divest its systems business, which includes substantially
all of the operating assets and cash flows that were obtained through the Snap Appliance and Eurologic Systems acquisitions as well as internally developed hardware and software. Accordingly, the
Company classified the systems business as a discontinued operation in the consolidated financial statements and is actively pursuing a sale of the systems business. In the fourth quarter of fiscal
2006, the Company recorded an impairment charge of

on the long-lived assets held for sale to adjust the carrying value of these assets to fair value, less cost to sell.

On
January 31, 2006, the Company signed a definitive agreement with Sanmina-SCI Corporation and its wholly owned subsidiary, Sanmina-SCI USA, Inc.,
for the sale of the Company's OEM block-based systems business for $14.5 million, of which $5.0 million will be received over the next two years. In addition, Sanmina-SCI USA
agreed to pay the Company contingent consideration of up to an additional $12.0 million if certain revenue levels are achieved over a three-year period. The Company recorded a gain
of $12.1 million on the disposal of the OEM block-based systems business in the fourth quarter of fiscal 2006.

The
Company's investment portfolio consists of both corporate and government securities that have a maximum maturity of three years. The longer the duration of these securities, the more
susceptible they are to changes in market interest rates and bond yields. As yields increase, those securities purchased with a lower yield-at-cost show a
mark-to-market unrealized loss. All unrealized losses are due to changes in interest rates and bond yields. The Company expects to realize the full value of all these
investments upon maturity or sale.

The
amortized cost and estimated fair value of investments in available-for-sale debt securities at March 31, 2006, by contractual maturity, were as

Goodwill
is not amortized, but instead is reviewed annually and whenever events or circumstances occur which indicate that goodwill might be impaired. Impairment of goodwill is tested at
the Company's reporting unit level which is at the segment level by comparing each segment's carrying amount, including goodwill, to the fair value of that segment. To determine fair value, the
Company's review process uses the income, or discounted cash flows approach and the market approach. In performing its analysis, the Company uses the best information available under the
circumstances, including reasonable and supportable assumptions and projections. If the carrying amount of the segment exceeds its implied fair value, goodwill is considered impaired and a second step
is performed to measure the amount of impairment loss, if any.

In
connection with the segment reorganization in fiscal 2006, which is discussed in Note 16, an assessment of the recoverability of goodwill was performed. As a result of this
review, the Company wrote-off its entire balance of goodwill of $90.6 million in the second quarter of 2006. Factors that led to

F-18

---



this
conclusion were industry technology changes such as the shift from parallel to serial technology and the migration of core functionality to server chipsets; required increased investments that
eventually led the Company to sell the IBM i/p Series RAID Business and the proposed sale of the systems business; continued losses associated with sales of systems to IBM; and general market
conditions.

Based
on its annual review of goodwill in the fourth quarter of fiscal 2005, the Company recorded an impairment charge of $52.3 million related to its former Channel segment.
Factors that led to this conclusion included, but were not limited to, the negative impact of estimates of expected future income associated with increased costs related to recent acquisitions and
business alliances that occurred in fiscal 2005. These additional costs, along with industry technology transitions, place significant risk on the Company's ability to achieve and maintain
profitability, and, therefore have adversely impacted its profitability forecasts.

Intellectual
property assets consist of a patent license fee (Note 14), a technology license fee (Note 14), an amount allocated to a product supply agreement
(Note 14) and certain intellectual property acquired in fiscal 2003.

In
August 2004, the Company entered into an agreement to sell external storage products to IBM. In connection with the agreement, the Company issued IBM a warrant to purchase
250,000 shares of the
Company's common stock at an exercise price of $6.94 per share. The warrant has a term of five years from the date of issuance and was immediately exercisable. The warrant was valued at
$1.0 million using the Black-Scholes valuation model using a volatility rate of 62%, a risk-free interest rate of 4.0% and an estimated life of 5 years. The value of the
warrant was fully expensed, as the economic benefits were not considered probable, at March 31, 2005.

Other
intangible assets increased by approximately $57.0 million in fiscal 2005 as a result of the Company's acquisitions of the IBM i/p Series RAID business and Snap Appliance
and an agreement entered into with IBM discussed above. Other intangible assets decreased by approximately $51.1 million in fiscal 2006 due to the sale of the Company's IBM i/p Series RAID
Business, sale of a portion of its systems business and the Company's plan to divest the remainder of the systems business. Amortization of

other
intangible assets was $13.8 million, $17.3 million and $22.1 million in fiscal 2006, 2005 and 2004, respectively.

3/4% Notes:In December 2003, the Company issued $225.0 million in aggregate principal amount of
3/4% Notes due December 22, 2023. The issuance costs associated with the 3/4% Notes totaled $6.8 million and the net proceeds to the Company from the
offering of the Notes were $218.2 million.

The
3/4% Notes are convertible at the option of the holders into shares of the Company's common stock, par value $0.001 per share, only under the following circumstances:
(1) prior to December 22, 2021, on any date during a fiscal quarter if the closing sale price of the Company's common stock was more than 120% of the then current conversion price of the
3/4% Notes for at least 20 trading days in the period of the 30 consecutive trading days ending on the last trading day of the previous fiscal quarter, (2) on or after
December 22, 2021, if the closing sale price of the Company's common stock was more than 120% of the then current conversion price of the 3/4% Notes, (3) if the Company
elects to redeem the 3/4% Notes, (4) upon the occurrence of specified corporate transactions or significant distributions to holders of the Company's common stock occur or
(5) subject to certain exceptions, for the five consecutive business day period following any five consecutive trading day period in which the average trading price of the 3/4%
Notes was less than 98% of the average of the sale price of the Company's common stock during such five-day trading period multiplied by the 3/4% Notes then current
conversion rate. Subject to the above conditions, each $1,000 principal amount of 3/4% Notes is convertible into approximately 85.4409 shares of the Company's common stock (equivalent
to an initial conversion price of approximately $11.704 per share of common stock).

F-20

---



The
Company may redeem some or all of the 3/4% Notes for cash on December 22, 2008 at a redemption price equal to 100.25% of the principal amount of the notes being
redeemed, plus accrued interest to, but excluding, the redemption date. After December 22, 2008, the Company may redeem some or all of the 3/4% Notes for cash at a redemption
price equal to 100% of the principal amount of the notes being redeemed, plus accrued interest to, but excluding, the redemption date.

Each
holder of the 3/4% Notes may require the Company to purchase all or a portion of their 3/4% Notes on December 22, 2008 at a price equal to
100.25% of the 3/4% Notes to be purchased plus accrued and unpaid interest. In addition, each holder of the 3/4% Notes may require the Company to purchase all or a
portion of their 3/4% Notes on December 22, 2013, on December 22, 2018 or upon the occurrence of a change of control (as defined in the Indenture governing the
3/4% Notes) at a price equal to the principal amount of 3/4% Notes being purchased plus any accrued and unpaid interest.

The
Company will pay cash interest at an annual rate of 3/4% of the principal amount at issuance, payable semi-annually on June 22 and
December 22 of each year, which interest payments commenced on June 22, 2004. Debt issuance costs of $6.8 million are being amortized to interest expense over 5 years. The
3/4% Notes rank senior in right of payment to the 3% Notes. The 3/4% Notes rank junior in right of payment of the 3% Notes and are subordinated to all other existing and
future senior indebtedness of the Company.

In
connection with the issuance of the 3/4% Notes, the Company purchased marketable securities totaling $7.9 million as security for the first ten scheduled
interest payments due on the 3/4% Notes. The marketable securities, which consist of United States government securities, are reported at fair market
value with unrealized gains and losses, net of income taxes, recorded in "Accumulated other comprehensive income, net of taxes" as a separate component of the stockholders' equity on the Consolidated
Balance Sheets. At March 31, 2006, $1.7 million was classified as short-term marketable securities due within one year and $3.1 million was classified as
long-term due within three years.

Convertible Bond Hedge and Warrant

Concurrent with the issuance of the 3/4% Notes, the Company entered into a convertible bond hedge transaction with an affiliate of one of the
initial purchasers of the 3/4% Notes. Under the convertible bond hedge arrangement, the counterparty agreed to sell to the Company up to 19.2 million shares of the Company's
common stock, which is the number of shares issuable upon conversion of the 3/4% Notes in full, at a price of $11.704 per share. The convertible bond hedge transaction may be settled at
the Company's option, either in cash or net shares, and expires in December 2008. Settlement of the convertible bond hedge in net shares on the expiration date would result in the Company
receiving a number of shares of its common stock with a value equal to the amount otherwise receivable on cash settlement. Should there be an early unwind of the convertible bond hedge transaction,
the amount of cash or net shares potentially received by the Company will depend upon then existing overall market conditions, and on the Company's stock price, the volatility of the Company's stock
and the amount of time remaining on the convertible bond hedge. The convertible bond hedge transaction cost of $64.1 million has been accounted for as an equity transaction in accordance with
EITF No. 00-19.

During
the fourth quarter of fiscal 2004, in conjunction with the issuance of the 3/4% Notes, the Company received $30.4 million from the issuance to an affiliate
of one of the initial purchasers of the 3/4% Notes of a warrant to purchase up to 19.2 million shares of the Company's common stock at an exercise price of $18.56 per share. The
warrant expires in December 2008. At expiration, the Company may, at its option, elect to settle the warrants on a net share basis or for cash. As of March 31, 2006, the warrant had

not
been exercised and remained outstanding. The warrant was valued using the Black-Scholes valuation model using a volatility rate of 42%, risk-free interest rate of 3.6% and an expected
life of 5 years. The value of the warrant of $30.4 million has been classified as equity because it meets all the equity classification criteria of EITF No. 00-19. The
separate warrant and convertible bond hedge transactions have the potential of limiting the dilution associated with the conversion of the 3/4% Notes from approximately
19.2 million to as few as 12.1 million shares.

3% Notes:In March 2002, the Company issued $250 million in aggregate principal amount of 3% Notes for net
proceeds of $241.9 million. The 3% Notes are due on March 5, 2007. The 3% Notes provide for semi-annual interest payments each March 5 and September 5, which
interest payments commenced September 5, 2002. The holders of the 3% Notes are entitled to convert the notes into
common stock at a conversion price of $15.31 per share through March 5, 2007. The 3% Notes are redeemable, in whole or in part, at the option of the Company, at any time on or after
March 9, 2005 at declining premiums to par. Debt issuance costs are amortized to interest expense ratably over the term of the 3% Notes. The Notes are subordinated to all other existing and
future senior indebtedness of the Company.

In
connection with the issuance of the 3% Notes, the Company purchased marketable securities totaling $21.4 million as security for the first six scheduled interest payments due
on the 3% Notes. The marketable securities, which consist of United States government securities, are reported at fair market value with unrealized gains and losses, net of income taxes, recorded in
"Accumulated other comprehensive income, net of taxes" as a separate component of the stockholders' equity on the Consolidated Balance Sheets. In fiscal 2004, the Company utilized a portion of the
proceeds from the issuance of 3/4% Notes and repurchased $214.8 million in aggregate principal amount of the 3% Notes, resulting in a loss on extinguishment of debt of
$5.7 million (including unamortized debt issuance costs of $5.0 million). Due to the partial repurchase of the 3% Notes, the restriction on $9.4 million of the restricted
marketable securities lapsed. At March 31, 2006, there was no restriction on cash in connection with the remaining $10.6 million aggregate principal amount outstanding 3% Note balance.

In
fiscal 2006, the Company repurchased $24.6 million in aggregate principal amount of its 3% Notes on the open market for an aggregate price of $24.3 million, resulting in
a loss on extinguishment of debt of $0.1 million (including unamortized debt issuance costs of $0.3 million). The loss on extinguishment of debt has been included in "Interest and other
income" in the Consolidated Statement of Operations.

Note 7. Stockholders' Equity

Employee Stock Purchase Plan:The Company has authorized 10,600,000 shares of common stock for issuance under the 1986 ESPP.
Qualified employees may elect to have a certain percentage (not to exceed 10%) of their salary withheld pursuant to the ESPP. The salary withheld is then used to purchase shares of the Company's
common stock at a price equal to 85% of the market value of the common stock at either the beginning of the offering period or at the end of each applicable six month purchase period, whichever is
lower. During fiscal 2001, the Company amended the ESPP to extend the offering period from six months to 24 months, beginning in August 2000. Purchases are made every six months. During
fiscal 2004, an additional 5,000,000 shares were added to the ESPP, making a total of 15,600,000 authorized shares under the 1986 ESPP. Under the ESPP, 1,624,000, 1,109,000 and 1,027,000 shares were
issued during fiscal 2006, 2005 and 2004, respectively, representing approximately $4.5 million, $5.4 million and $5.3 million in employees' contributions, respectively.

2004 Equity Incentive Plan:During the second quarter of fiscal 2005, the Company's Board of Directors and its stockholders
approved the Company's 2004 Equity Incentive Plan and reserved for issuance thereunder 10,000,000 shares of the Company's common stock plus shares reserved but not issued under the Company's 1999
Stock Option Plan and 2000 Nonstatutory Stock Option Plan. The 2004 Equity Incentive Plan provides for granting of nonstatutory stock options, restricted stock, stock awards, restricted stock units
and stock appreciation rights to employees, employee directors and consultants. Incentive stock options may also be granted to the Company's employees under the 2004 Equity Incentive Plan. As of
March 31, 2006, the Company had 13,689,367 shares available for future issuance under the 2004 Equity Incentive Plan.

2000 Nonstatutory Stock Option Plan:During the third quarter of fiscal 2001, the Company's Board of Directors approved the
Company's 2000 Nonstatutory Stock Option Plan and reserved for issuance thereunder 8,000,000 shares of common stock. The 2000 Nonstatutory Stock Option Plan provides for granting of stock options to
non-executive officer employees of the Company at prices equal to at least 100% of the fair market value at the date of grant. Stock options granted under this plan are for periods not to
exceed ten years and generally become fully vested and exercisable over a two to five-year period. Upon stockholder approval of the 2004 Equity Incentive Plan in August 2004, the
2000 Nonstatutory Stock Option Plan was terminated with respect to new option grants. There were no shares available for option grants under the 2000 Nonstatutory Stock Option Plan as of
March 31, 2006.

1999 Stock Option Plan:During the second quarter of fiscal 2000, the Company's Board of Directors and its stockholders
approved the Company's 1999 Stock Option Plan and reserved for issuance thereunder (a) 1,000,000 shares of common stock, plus (b) any shares of common stock reserved but ungranted under
the Company's 1990 Stock Option Plan as of the date of stockholder approval, plus (c) any shares returned to the 1990 Stock Option Plan as a result of termination of options under the 1990
Stock Option Plan after the date of stockholder approval of the 1999 Stock Option Plan. The 1999 Stock Option Plan provided for granting of incentive and nonstatutory stock options to employees,
consultants and directors of the Company. Options granted under this plan are for periods not to exceed ten years, and were granted at prices not less than 100% and 75% for incentive and nonstatutory
stock options, respectively, of the fair market value on the date of grant. Generally, stock options become fully vested and exercisable over a four to five-year period. Upon stockholder
approval of the 2004 Equity Incentive Plan in August 2004, the 1999 Stock Option Plan was terminated with respect to new option grants. There were no shares available for option grants under
the 1999 Stock Option Plan at March 31, 2006.

1990 Stock Option Plan:The Company's 1990 Stock Option Plan allowed the Board of Directors to grant to employees, officers,
and consultants incentive and nonstatutory options to purchase common stock or other stock rights at exercise prices not less than 50% of the fair market value of the underlying common stock on the
date of grant. The expiration of options or other stock rights did not exceed ten years from the date of grant. The Company has issued all stock options under this plan at exercise prices of at least
100% of fair market value of the underlying common stock on the respective dates of grant. Generally, options vest and become exercisable over a four-year period. In March 1999, the
Company amended the 1990 Stock Option Plan to permit non-employee directors of the Company to participate in this plan. Upon stockholder approval of the 1999 Stock Option Plan, the 1990
Stock Option Plan was terminated with respect to
new option grants. There were no shares available for option grants under the 1990 Stock Option Plan at March 31, 2006.

Stock Option PlansDirectors

The 2000 Director Stock Option Plan:During the second quarter of fiscal 2001, the Company's Board of Directors approved the
Company's 2000 Director Stock Option Plan and reserved for issuance thereunder 1,000,000 shares of common stock. The 2000 Director Stock Option Plan provides for the automatic grant to
non-employee directors of nonstatutory stock options to purchase common stock at the fair market value of the underlying common stock on the date of grant, which is generally the last day
of each fiscal year except for the first grant to any newly elected director. Upon joining the Board of Directors, each new non-employee director receives an option to purchase 40,000
shares of the Company's common stock which vests over four years and expires ten years after the date of grant. On the last day of each fiscal year, each non-employee director receives an
option to purchase 15,000 shares of the Company's common stock which vests over a one-year period and expires ten years after the date of grant. As of March 31, 2006, the Company
had 233,750 shares available for future issuance under the 2000 Director Stock Option Plan.

The 1990 Directors' Stock Option Plan:The 1990 Directors' Stock Option Plan provides for the automatic grant to
non-employee directors of non-statutory stock options to purchase common stock at the fair market value of the underlying common stock on the date of grant, which is generally
the last day of each fiscal year except for the first grant to any newly elected director. Upon joining the Board of Directors, each new non-employee director received an option to
purchase 40,000 shares of the Company's common stock which vests over four years and, prior to March 31, 1997, expired five years after the date of grant. Prior to March 31, 1997, each
director received a grant at the end of each fiscal year for 10,000 shares, which vested quarterly and over a four-year period and expired five years after the date of grant. During fiscal
1997, the Company amended the 1990 Directors' Stock Option Plan such that all newly issued options expire ten years after the date of grant and all newly issued annual options vest over a
one-year period. In fiscal 1999, the Company amended the 1990 Directors' Stock Option Plan to increase the annual grant to 15,000 options for the fiscal year ended March 31, 1999.
Upon the approval of the 2000 Director Stock Option Plan, the 1990 Director Option Plan was terminated with respect to new grants. There were no shares available for option grants under the 1990
Directors' Stock Option Plan at March 31, 2006.

Rights Plan

The Company has reserved 250,000 shares of Series A Preferred Stock for issuance under the 1996 Rights Agreement, which was amended and restated on
February 1, 2001. Under this plan, stockholders have received one preferred stock purchase right ("Right") for each outstanding share of the Company's common stock. The Rights trade
automatically with shares of the Company's common stock. The Rights are not exercisable until ten days after a person or group announces the acquisition of 20% or more of the Company's outstanding
common stock or the commencement of a tender offer which would result in ownership by a person or group of 20% or more of the then outstanding common stock. If one of these events occurs,
stockholders, other than an acquiring person, would be entitled to exercise their rights and receive one-thousandth of a share of Series A Preferred Stock for each Right they hold
at an exercise price of $180.00 per right.

The
Company is entitled to redeem the Rights at $0.01 per Right anytime on or before the day following the occurrence of an acquisition or tender offer described in the preceding
paragraph. This redemption period may be extended by the Company in some cases. If, prior to such redemption, the Company is acquired in a merger or other business combination, a party acquires 20% or
more of the Company's common stock, a 20% stockholder engages in certain self-dealing transactions, or the Company sells 50% or more of its assets, then in lieu of receiving shares of
Series A Preferred Stock for each Right held, stockholders, other than an acquiring person, would be entitled to exercise their Rights and receive from the surviving corporation, for an
exercise price of $180.00 per right, common stock having a then current market value of $360.00.

The
Series A Preferred Stock purchasable upon exercise of the Rights will not be redeemable. Each share of Series A Preferred Stock will be entitled to an aggregate
dividend of 1,000 times the dividend declared per common stock. In the event of liquidation, the holders of the Series A Preferred Stock will be

F-27

---



entitled
to a preferential liquidation payment equal to 1,000 times the per share amount to be distributed to the holders of the common stock. Each share of Series A Preferred Stock will have
1,000 votes, voting together with the common stock. In the event of any merger, consolidation or other transaction in which the common stock is changed or exchanged, each share of Series A
Preferred Stock will be entitled to receive 1,000 times the amount received per common stock. These rights are protected by customary anti-dilution provisions.

Shares Reserved for Future Issuance

As of March 31, 2006, the Company has reserved the following shares of authorized but unissued common stock:

The
Company has been, or is, subject to IRS audits for its fiscal years 1994 through 2003. The fiscal 1994 through fiscal 1996 cycle, which is docketed in the United States Tax Court,
was resolved in December 2001. The outcome did not have a material adverse effect on the Company's financial position or results of operations, as sufficient tax provisions had been made. The
final Tax Court stipulation will be filed when the subsequent audit cycles are completed. Tax credits that were generated but not used in subsequent years may be carried back to the fiscal 1994 to
1996 audit cycle.

On
December 15, 2000, the Company received a statutory notice of deficiency from the IRS with respect to its Federal income tax return for fiscal 1997. The Company filed a
Petition with the United States Tax Court on March 14, 2001, contesting the asserted deficiencies. Settlement agreements have been filed with the United States Tax Court on all but one issue.
The Company believes that the final outcome of all issues will not have a material adverse impact on its financial position or results of operations, as the Company believes that it has meritorious
defenses against the asserted deficiencies and any proposed adjustments and that it has made sufficient tax provisions. However, the Company cannot predict with certainty how these matters will be
resolved and whether it will be required to make additional payments.

In
addition, the IRS is currently auditing the Company's Federal income tax returns for fiscal 1998 through fiscal 2003. In the third quarter of fiscal 2005, the Company resolved all
issues for fiscal 1998 through fiscal 2001, other than the rollover impact of any potential resolution on the remaining fiscal 1997 issue and tax credits that were generated but not used in subsequent
years that may be carried back. The Company believes that it has provided sufficient tax provisions for these years and the ultimate outcome of the IRS audits will not have a material adverse impact
on its financial position or results of operations in future periods. However, the Company cannot predict with certainty how these matters will be resolved and whether the Company will be required to
make additional tax payments.

The
Company is a party to other litigation matters and claims, including those related to intellectual property, which are normal in the course of its operations, and while the results
of such litigation matters and claims cannot be predicted with certainty, the Company believes that the final outcome of such matters will not have a material adverse impact on its financial position
or results of operations.
However, because of the nature and inherent uncertainties of litigation, should the outcome of these actions be unfavorable, the Company's business, financial condition, results of operations and cash
flows could be materially and adversely affected.

Note 9. Restructuring Charges

During fiscal years 2006, 2005 and 2004, the Company recorded restructuring charges of $10.4 million, $5.9 million and $4.3 million,
respectively. All expenses, including adjustments, associated with the Company's restructuring plans are included in "Restructuring charges" in the Consolidated Statements of Operations and are not
allocated to segments, but rather managed at the corporate level. The restructuring plans are discussed in detail below.

Fiscal 2006 Restructuring Plans

In the third and fourth quarters of fiscal 2006, management approved and initiated a plan to restructure the Company's operations by simplifying the Company's
infrastructure. These restructuring plans eliminated certain duplicative resources in all functions of the organization worldwide, due in part, to the discontinued operations, the vacating of
redundant facilities in order to reduce the Company's cost

structure,
and the sale of the Company's Singapore manufacturing facility. This resulted in a restructuring charge of $7.4 million for the fourth quarter of fiscal 2006.

The
following table sets forth an analysis of the components of the fiscal 2006 restructuring charge and the provision adjustment and payments made against the reserve through
March 31, 2006:

The
Company anticipates that the remaining restructuring reserve balance of $1.7 million will be substantially paid out by the second quarter of fiscal 2008,
primarily attributable to longer term lease obligations.

Fiscal 2005 Restructuring Plans

In fiscal 2005, the Company implemented restructuring plans to streamline the corporate organization, thereby reducing operating costs by consolidating
duplicative resources in connection with the acquisition of Snap Appliance and the Vitesse strategic alliance and costs pertaining to estimated future obligations for non-cancelable lease
payments for excess facilities in Germany and United Kingdom. This resulted in a restructuring charge of $5.8 million, of which $5.2 million related to the involuntary termination of
employees in all functions of the organization and $0.6 million related to the estimated loss on the Company's facilities. During fiscal years 2006 and 2005, the Company recorded adjustments to
the fiscal 2005 restructuring plan of $0.4 million and $0.2 million, respectively, related to the reduction of severance and benefits as actual results were lower than anticipated and a
reduction of lease costs related to the estimated loss on the Company's facilities. As of March 31, 2006, the Company had utilized all of these charges and the plan is now complete.

Fiscal 2004 Restructuring Plans

In fiscal 2004, the Company's management implemented restructuring plans to consolidate primarily research and development resources, the involuntary termination
of certain technical support, marketing and administrative personnel, the shutdown of the Company's Hudson, Wisconsin facility, and asset impairments associated with the identification of duplicative
assets and facilities. As a result, the Company recorded a restructuring charge of $3.7 million, of which $3.3 million related to severance and benefits to 30 employees. The Company
recorded an adjustment to the fiscal 2004 restructuring provision of $0.2 million in fiscal 2005 as a reduction of severance and benefits as actual results were lower than anticipated, offset
by an adjustment of $0.6 million in fiscal 2004 related to the additional lease costs. As of March 31, 2006, the Company had utilized all of these charges and the plan is now complete.

Fiscal 2003 Restructuring Plan

In the fourth and second quarters of fiscal 2003, the Company announced restructuring programs (collectively called the fiscal 2003 restructuring provision) to
reduce expenses and streamline operations and recorded a restructuring charge of $13.2 million. During fiscal years 2004 and 2003, the Company

F-30

---



recorded
adjustments to the fiscal 2003 restructuring provision of $0.2 million and $0.1 million, respectively, related to the reduction of severance and benefits as actual results were
lower than anticipated, offset by additional lease costs. As of March 31, 2004, the Company had substantially completed its execution of the fiscal 2003 restructuring provision. During fiscal
2006, the Company recorded additional adjustments to the fiscal 2003 restructuring provision of $0.2 million related to the additional lease costs. As of March 31, 2006, the remaining
accrual balance of $0.1 million relates to the estimated loss related to facility in Florida through April 2008, the end of the lease term.

Fiscal 2002 Restructuring Plan

In the fourth and first quarters of fiscal 2002, the Company's management implemented restructuring plans (collectively called the fiscal 2002 restructuring
provision) to reduce costs, improve operating efficiencies and tailor the Company's expenses to current revenues and recorded a restructuring charge of $10.1 million. During fiscal years 2006,
2004, 2003 and 2002, the Company recorded adjustments to the fiscal 2002 restructuring provision of $0.4 million, $0.2 million, $0.6 million and $0.4 million, respectively,
related to the additional lease costs offset by a reduction of severance and benefits as actual results were lower than anticipated. As of March 31, 2006, the remaining accrual balance of
$0.4 million relates to the estimated loss on a facility in Florida through the end of the lease term, which is April 2008.

Fiscal 2001 Restructuring Plan

In the fourth quarter of fiscal 2001, the Company's management implemented a restructuring plan (the fiscal 2001 restructuring provision) in response to the
economic slowdown to reduce costs and improve operating efficiencies and recorded a restructuring charge of $9.9 million. During fiscal years 2003 and 2002, the Company recorded additional
charges of $0.7 million and $0.3 million, respectively, related to additional lease costs and the write-off of certain manufacturing equipment that was being held for sale,
which was offset by a reduction of severance and benefits as actual results were lower than anticipated. As of March 31, 2004, the Company substantially completed its execution of the 2001
restructuring provision. The remaining accrual balance relates to the estimated loss of a facility that the Company subleased in California through April 2008, the end of the lease term. The
estimated loss represents the estimated future obligations for the non-cancelable lease payments, net of the estimated future sublease income. In fiscal years 2006 and 2005, the Company
recorded additional adjustments of $0.2 million and $0.5 million, respectively, related to additional lease costs. As of March 31, 2006, the Company anticipates that the remaining
restructuring reserve balance relating to lease obligations of $0.5 million will be substantially paid out by the first quarter of fiscal 2009.

The

Note 10. Other Charges (Gains)

Other charges (gains) consist of asset impairment charges related to certain properties or assets and minority investments. Other charges (gains) also included
charges associated with the Company's strategic alliances with ServerEngines LLP ("ServerEngines") and Vitesse. The Company recorded a gain on the sale of assets of $0.3 million in fiscal 2005
and asset impairment charges of $1.6 million and $6.0 million in fiscal years 2006 and 2004, respectively.

On
December 23, 2005, the Company entered into a three-year contract manufacturing agreement with Sanmina-SCI whereby Sanmina-SCI, upon the
closing of the transaction on January 9, 2006, assumed manufacturing operations of Adaptec products. In addition, the Company sold certain manufacturing assets, buildings and improvements and
inventory located in Singapore to Sanmina-SCI for $26.6 million (net of closing costs of $0.6 million). In connection with this agreement, the Company recorded a loss on
disposal of assets of $1.6 million that was recorded in fiscal 2006 in "Other charges (gains)" on the Consolidated Statements of Operations.

On
March 16, 2005, the Company entered into a strategic alliance with ServerEngines, to develop and market the next generation IP storage products. Under the terms of the
alliance, ServerEngines employed 33 of the Company's former engineering employees and licensed certain technology and acquired certain assets related to the Company's iSCSI and TCP/IP offload protocol
engines. On January 26, 2005, the Company entered into a strategic alliance with Vitesse Semiconductor Corporation to develop and market the next generation Serial Attached SCSI products. Under
the terms of the alliance, Vitesse employed 44 of the Company's former engineering employees and licensed certain Serial Attached SCSI technology and assets related to the Company's development of
Serial Attached
SCSI ROC products. As a result, the Company incurred charges in fiscal 2005 of $0.9 million and $1.6 million for severance, benefits, loss on the sale of property and equipment and legal
fees associated with the ServerEngines and Vitesse alliances, respectively.

In
fiscal 2004, the Company recorded an impairment charge of $5.0 million to reduce the carrying value of certain properties classified as assets held for sale to fair value less
cost to sell. The Company decided to consolidate its properties in Milpitas, California to better align its business needs with existing operations and to provide more efficient use of its facilities.
As a result, two owned buildings, including associated building improvements and property, plant and equipment, were classified as assets held for sale and were included in "Other current assets" in
the Consolidated Balance Sheets at March 31, 2004 at their expected fair value less expected cost to sell. In October 2004, the Company completed the sale of these properties that were
previously classified as held for sale. Net proceeds from the sale of the properties aggregated $9.6 million, which exceeded the Company's final revised fair value of $6.8 million. As a
result, a gain on the sale of the properties of $2.8 million was recorded in fiscal 2005 as a credit to "Other charges (gains)" in the Consolidated Statements of Operations.

The
Company holds minority investments in certain non-public companies. The Company regularly monitors these minority investments for impairment and records reductions in the
carrying values when necessary. Circumstances that indicate an other-than-temporary decline include valuation ascribed to the issuing company in subsequent financing rounds,
decreases in quoted market price and declines in operations of the issuer. The Company recorded an impairment charge of $1.0 million in fiscal 2004 related to a decline in the value of a
minority investment deemed to be other-than-temporary.

In
June 2004, the Company, Nevada SCSI Enterprises, Inc. and Thomas A. Gafford (jointly, "NSE") entered into a license and release agreement, pursuant to
which the Company paid NSE $1.3 million as a one-time, fully paid-up license fee to settle NSE's claims that some of the Company's products infringed certain patents.
The license and release agreement expressly excluded any sales of products made by Eurologic prior to the Company's April 2003 acquisition of
Eurologic. In November 2004, the Company exercised its option to secure a license and release with respect to such Eurologic sales by payment to NSE of a royalty fee of $0.4 million. The
Company has filed a claim against the Eurologic acquisition Holdback for the $0.4 million royalty it paid with respect to Eurologic's pre-acquisition sales. The Eurologic
shareholders are disputing the Company's right to withhold the $0.4 million from the Holdback.

In
December 1999, the Company purchased Distributed Processing Technology Corporation ("DPT"). As part of the purchase agreement, $18.5 million of the purchase price was
held back ("Holdback Amount") from former DPT stockholders for unknown liabilities that may have existed as of the acquisition date. The Holdback Amount was included in "Accrued liabilities" in the
Consolidated Balance Sheet at March 31, 2003. Subsequent to the date of purchase, the Company determined that certain representations and warranties made by the DPT stockholders were incomplete
or inaccurate, which caused the Company to lose revenues and incur additional expenses. This caused the Company to file court proceedings against Steven Goldman, the principal shareholder and former
president of DPT, alleging causes of action for, amongst others, fraud, fraudulent inducement, and negligent misrepresentation. In May 2003, the Company entered into a written settlement and
mutual general release agreement with Steven Goldman, on his own and on behalf of all the selling shareholders of DPT, pursuant to which it was agreed that the Company would retain the Holdback Amount
and, additionally, Steven Goldman would pay the Company $31.0 million. The Company received the $31.0 million payment in May 2003 and recorded a gain of approximately
$49.3 million in fiscal 2004. The cash received from the DPT settlement of $31.0 million was included in cash provided from operating activities in the Consolidated Statements of Cash
Flows.

The
Company continuously monitors the circumstances impacting the expected realization of its deferred tax assets on a jurisdiction by jurisdiction basis. At
March 31, 2006, the Company's analysis of its deferred tax assets demonstrated that it was more likely than not that substantially all of its U.S. deferred tax assets would not be realized.
Factors that led to this conclusion included, but were not limited to, the Company's past operating results, cumulative tax losses in the U.S., and uncertain future income on a jurisdiction by
jurisdiction basis.

As
of March 31, 2006 the Company had net operating loss carryforwards of $57.3 million for federal and $6.0 million for state purposes that expire in various years
beginning in 2021 for federal and 2013 for state purposes. The Company also had research and development credits of $12.9 million for federal purposes that expire in various years beginning in
2019 and $2.8 million credits for state purposes that carry forward indefinitely until fully exhausted. Of the federal net operating loss carryforwards, $7.5 million were related to
stock option deductions, the tax benefit of which will be credited to paid in capital when realized.

The
Company's subsidiary in Singapore operated under a tax holiday through March 31, 2006. As the result of the Company's divestiture of its manufacturing
operations in Singapore, the Company is in the process of terminating its tax holiday status and restructuring its foreign operations. The Company is currently making modification to its international
tax structure to reflect its revised foreign operations. The Company does not expect these changes, in and of themselves, to cause its worldwide effective tax rate to differ materially.

In
the fourth quarter of fiscal 2005, the Company repatriated $360.6 million of undistributed earnings from Singapore to the United States, resulting in a tax liability of
$17.6 million. The one-time deduction is allowed to the extent that the repatriated amounts are used to fund a qualified Domestic Reinvestment Plan, as required by the Act. If the
Company does not spend the repatriated funds in accordance with its reinvestment plan, the Company may incur additional tax liabilities. The Company has not provided for U.S. deferred income taxes or
foreign withholding taxes on the remaining undistributed earnings of $257.2 million since these earnings are intended to be
reinvested indefinitely. Although the Company does not have any current plans to repatriate the remaining undistributed earnings from its Singapore subsidiary to its United States parent company, if
the Company were to do so, additional income taxes at the combined United States Federal and state statutory rate of approximately 40% could be incurred from the repatriation.

The
Company's tax related liabilities were $46.7 million and $57.5 million at March 31, 2006 and 2005, respectively. Tax related liabilities are primarily composed
of income, withholding and transfer taxes accrued by the Company in the taxing jurisdictions in which it operates around the world, including, but not limited to, the United States, Singapore,
Ireland, United Kingdom, Japan and Germany. The amount of the liability was based on management's evaluation of the Company's tax exposures in light of the complicated nature of the business
transactions entered into by the Company in a global business environment. In fiscal years 2006 and 2005, net tax related liabilities were released totaling $0 million and $26.4 million,
respectively, as the result of favorable outcomes of certain U.S. tax controversies. The Company also continuously reviews its tax related liabilities to ensure that it is appropriate by considering
tax controversy factors such as the period covered by the cause of action, the degree of probability of an unfavorable outcome, its ability to reasonably estimate the liability, the timing of the
liability and how it will impact the Company's other tax attributes. At March 31, 2006, the Company believed that the tax

liability recorded on its Consolidated Balance Sheet was sufficient to cover all known tax exposures.

Note 13. Net Income (Loss) Per Share

Basic net income (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Diluted
net income (loss) per share gives effect to all potentially dilutive common shares outstanding during the period, which include certain stock options and warrants, calculated using the treasury stock
method, and convertible notes which are potentially dilutive at certain earnings levels, and are computed using the if-converted method.

A
reconciliation of the numerator and denominator of the basic and diluted income (loss) per share computations for continuing operations, discontinued operations and net income (loss)
were as follows:

Diluted
loss per share from continuing operations, discontinued operations and net loss for fiscal years 2006 and 2005 was based only on the weighted-average number of shares outstanding
during each of the periods, as the inclusion of any common stock equivalents would have been anti-dilutive. In addition, certain potential common shares were excluded from the diluted
computation from continuing operations, discontinued operations and net income for fiscal 2004 because their inclusion would have been anti-dilutive. The items excluded for fiscal years
2006, 2005 and 2004 were as follows:

Note 14. IBM Distribution Agreement, ServeRAID Agreement and Patent Cross-License Agreement

In December 2004, the Company entered into a distribution agreement on its RAID controllers and connectivity products sold for IBM iSeries and pSeries
servers. The agreement was made through an

F-38

---



amendment
to the Company's existing i/p Series RAID supply and intellectual property agreement entered into June 2004 (See Note 2). The distribution agreement was accounted for as a
standalone transaction as it was not contemplated at the time the Company entered into the original IBM i/p Series RAID transaction.

Under
an amended intellectual property agreement with IBM, the Company was required to make fixed and variable royalty-based payments to IBM. The fixed payments potentially due under the
arrangement total $52.1 million, of which $25.0 million was paid in December 2004, the date the Company entered into the agreement, and the remainder was due quarterly, in varied
installments, through December 2008. A portion of the $52.1 million in total payments was contingent upon IBM purchasing certain levels of the Company's products. Upon entering into the
agreement, the Company recorded the full remaining amount payable to IBM as a liability in the Consolidated Balance Sheets as the Company considered payment of the full amount to be probable. At
March 31, 2005, $11.6 million was recorded in "Accrued Liabilities" and $11.9 million was recorded in "Other Long-Term Liabilities" in the Consolidated Balance Sheets.

The
fixed consideration for the distribution agreement of $52.1 million was recorded as an asset to "Prepaid expenses" and "Other long-term assets" in the Consolidated
Balance Sheets at March 31, 2005 and the amortization was being included in "Net revenues" in the Consolidated Statements of Operations over a four-year period, reflecting the
pattern in which the economic benefits of the assets expected to be realized. The royalty-based fee per unit was calculated using the average net sales price for units sold within the quarter and
baseline royalty rates subject to certain adjustment factors. The amortization of the fixed consideration and the royalty-based payments were being recorded as a reduction to revenue in the period the
units were sold. On September 30, 2005, the Company sold the IBM i/p Series RAID Business to IBM. As a result, the distribution agreement was cancelled as part of the sale and the forementioned
assets and liabilities have been removed from the Consolidated Balance Sheet as of March 31, 2006.

In
March 2002, the Company entered into a non-exclusive, perpetual technology licensing agreement and an exclusive three-year product supply agreement with
IBM. The technology licensing agreement grants the Company the right to use IBM's ServeRAID technology for the Company's internal and external RAID products. Under the product supply agreement, the
Company will supply RAID software, firmware and hardware to IBM for use in IBM's xSeries servers.
The agreement does not contain minimum purchase commitments from IBM and the Company cannot be assured of the future revenue it will receive under this agreement. Either party may terminate the
technology licensing agreement if the other party materially breaches its obligations under the agreement. The product supply agreement automatically terminates at the end of three years or earlier
upon breach of a material contract obligation by the Company or upon the occurrence of any transaction within two years of the effective date of the agreement that results in: (i) a competitor
of IBM beneficially owning at least 10% of the voting stock of the Company or any affiliate of the Company; (ii) a competitor of IBM becoming entitled to appoint a nominee to the board of
directors of the Company; or (iii) a director, office holder or employee of a competitor of IBM becomes a director of the Company.

In
consideration, the Company paid IBM a non-refundable fee of $26.0 million and issued IBM a warrant to purchase 150,000 shares of the Company's common stock at an
exercise price $15.31 per share. The warrant has a term of five years from the date of issuance and is immediately exercisable. The warrant was valued at approximately $1.0 million using the
Black-Scholes valuation model using a volatility rate of

F-39

---



71.6%,
a risk-free interest rate of 4.7% and an estimated life of five years. The Company allocated $12.0 million of the consideration paid to IBM to the supply agreement and
allocated the remainder to the technology license fee. Fair values were determined based on discounted estimated future cash flows related to the Company's channel and OEM ServeRAID business. The cash
flow periods used were five years and the discount rates used were 15% for the supply agreement asset and 20% for the technology license fee based upon the Company's estimate of their respective
levels of risk. Amortization of the supply agreement and the technology license fee shall be included in "Net revenues" and "Costs of revenues," respectively, over a five-year period
reflecting the pattern in which economic benefits of the assets are realized.

In
May 2000, the Company entered into a patent cross-license agreement with IBM, which was subsequently amended in March 2002. Under the agreement, the Company obtained a
release of past infringement claims made prior to January 1, 2000 and received the right to use certain IBM patents from January 1, 2000 through June 30, 2007. Additionally, the
Company granted IBM a license to use all of the Company's patents for the same period. In consideration, the Company paid an aggregate patent fee of $13.3 million. The patent license fee is
being amortized over the period from January 1, 2000 through June 30, 2007.

Note 15. Guarantees

Intellectual Property Indemnification Obligations

The Company has entered into agreements with customers and suppliers that include intellectual property indemnification obligations. These indemnification
obligations generally require the Company to compensate the other party for certain damages and costs incurred as a result of third party intellectual property claims arising from these transactions.
In each of these circumstances, payment by the Company is conditional on the other party making a claim pursuant to the procedures specified in the particular contract, which procedures typically
allow the Company to challenge the other party's claims. Further, the Company's obligations under these agreements may be limited in terms of time and/or amount, and in some instances, the Company may
have recourse against third parties for certain payments made by it under these agreements. It is not possible to make a reasonable estimate of the maximum potential amount of future payments under
these or similar agreements due to the conditional nature of the Company's obligations and the unique facts and circumstances involved in each particular agreement. Historically, the Company has not
incurred significant costs to defend lawsuits or settle claims related to such agreements and no amount has been accrued in the accompanying consolidated financial statements with respect to these
indemnification guarantees.

Product Warranty

The Company provides an accrual for estimated future warranty costs based upon the historical relationship of warranty costs to sales. The estimated future
warranty obligations related to product sales are recorded in the period in which the related revenue is recognized. The estimated future warranty obligations are affected by product failure rates,
material usage and replacement costs incurred in correcting a product failure. If actual product failure rates, material usage or replacement costs differ from the Company's estimates, revisions to
the estimated warranty obligations would be required; however the Company made no adjustments to pre-existing warranty accruals in fiscal 2006 and 2005.

Note 16. Segment, Geographic and Significant Customer Information

Segment Information

In the second quarter of fiscal 2006, the Company reorganized its internal organization structure related to its former OEM and Channel segments. Where previously
the Company's former OEM and Channel segments each offered an integrated set of customer-focused products, the new organization is managed at the product level.

Following
the reorganization, the Company operated in two segments: DPS and DSG. A description of the types of customers or products and services provided by each segment is as follows:



The
unallocated corporate income and expenses, which are in the "Other" category, include amortization of acquisition-related intangible assets, restructuring charges, goodwill
impairment, other charges (gains), interest and other income, interest expense, all administrative expenses and certain research and development, selling and marketing expenses.

Summarized
financial information on the Company's segments, under the new organizational structure, is shown in the following table. The segment financial data for fiscal years 2006,
2005 and 2004 has been restated to reflect this change. There were no inter-segment revenues for the periods shown below. The Company does not separately track all tangible assets or depreciation by

Note 17. Business Acquisitions

The acquisitions described below were previously accounted for as purchase transactions and, accordingly, the results of operations and financial position of the
acquired businesses were included in the Company's financial statements as of the respective effective dates of the acquisitions. However, as a result of the sale of the IBM i/p Series RAID Business
and the Company's plan to divest its systems business, the assets expected to be sold have been classified as Assets and Liabilities of Discontinued Operations on the Consolidated Balance Sheet at
March 31, 2006 and the related results of operations have been reclassified to "Income (loss) from discontinued operations, net of taxes" on the
Consolidated Statements of Operations, as discussed in Note 2. This primiarly related to the IBM i/p Series RAID Business, Snap Appliance and Eurologic acquisitions.

IBM i/p Series RAID:On June 29, 2004, the Company completed the acquisition of the IBM i/p Series RAID component
business line consisting of certain purchased RAID data protection intellectual property, semiconductor designs and assets, and licensed from IBM related RAID intellectual property. The licensing
agreement granted the Company the right to use IBM's RAID technology and embedded Power PC technology for the Company's internal and external RAID products to be sold to IBM and other customers. In
conjunction with the acquisition, the Company also entered into a three-year exclusive product supply agreement under which the Company agreed to supply RAID software, firmware and
hardware to IBM for use in IBM's iSeries and pSeries servers. The Company also entered into an agreement for IBM to provide silicon wafer manufacturing processing services to the Company for the term
of the supply agreement at agreed upon rates.

The
final purchase price was $49.3 million, which consisted of a cash payment to IBM of $47.5 million, warrants valued at $1.1 million, net of registration costs,
and transaction costs of $0.7 million. This purchase price included a final adjustment of $0.2 million in the first quarter of fiscal 2006 to both goodwill and acquisition costs. In
connection with the acquisition, the Company issued a warrant to IBM to

F-43

---



purchase
250,000 shares of the Company's common stock at an exercise price of $8.13 per share. The warrant has a term of 5 years from the date of issuance and is immediately exercisable. The
warrant was valued using the Black-Scholes valuation model using a volatility rate of 62%, a risk-free interest rate of 3.9% and an estimated life of 5 years. The transaction costs
consisted primarily of legal, valuation and other fees.

The
IBM i/p Series RAID business was accounted for as a purchase business combination with the allocation of the purchase price to the tangible and intangible assets acquired are
summarized below (in thousands). The allocation was based on management's estimates of fair value, which included an independent appraisal.

The
values allocated to the supply agreement, patents and core technology and foundry agreement were being amortized over estimated useful lives of 3 to 5 years, reflecting the
pattern in which the economic benefits of the assets were expected to be realized. The estimated weighted average useful life of other intangible assets, created as a result of the acquisition of the
IBM i/p Series RAID business, were estimated to approximate 5 years. No residual value was estimated for the intangible assets. A portion of goodwill was not expected to be deductible for tax
purposes.

Snap Appliance:On July 23, 2004, the Company completed the acquisition of Snap Appliance, a provider of NAS products,
to expand its product offerings in the external storage market and to deliver cost-effective, scalable and easy-to-use DAS, NAS, Fibre Channel and
IP-based SAN products from the workgroup to the data center. The final purchase price was $83.7 million, consisting of $76.7 million in cash and transaction fees and
$7.0 million related to the fair value of assumed stock options to purchase 1.2 million shares of the Company's common stock. This purchase price included a final adjustment of
$0.7 million in the first quarter of fiscal 2006 to both goodwill and acquisitions costs. The assumed stock options were valued using the Black-Scholes valuation model with the following
assumptions: volatility rate of 58%; a risk-free interest rate of 2.6%; and an estimated life of 2.25 years.

Of
the total assumed stock options, stock options to purchase approximately 0.7 million shares of the Company's common stock, with exercise prices ranging between $1.42 and $5.66
per share, were unvested (the "Snap Unvested Options"). The Snap Unvested Options have a ten-year term and vest primarily over four years from the date of grant. The intrinsic value of the
Snap Unvested Options of $3.6 million was accounted for as deferred stock-based compensation and is being recognized as compensation expense over the related vesting periods.

The
values allocated to the core and existing technologies and trade name created as a result of the acquisition of Snap Appliance were being amortized over an estimated weighted average
useful life of seven years, reflecting the pattern in which the economic benefits of the assets are expected to be realized. No residual value was estimated for the intangible assets. Goodwill was not
expected to be deductible for tax purposes.

In
addition, a management incentive program was established to pay former employees of Snap Appliance cash payments totaling $13.8 million, which is being paid, contingent upon
their employment with the Company, over a two-year period through the second quarter of fiscal 2007. Payments under the management incentive program will be expensed as employees meet
their employment obligations or are recorded as part of the Snap Appliance acquisition-related restructuring for involuntarily terminations by the Company. Any amounts outstanding as of the completion
of the sale of the systems business, which includes Snap Appliance, will be accelerated.

F-45

---



A
portion of the Snap Appliance acquisition price totaling $5.4 million was held back, and in connection with the management incentive program, $1.3 million will be held
back for a total of $6.7 million (the "Snap Appliance Holdback") for unknown liabilities that may have existed as of the acquisition date. The Snap Appliance Holdback was paid in the second
quarter of fiscal 2006, except for funds necessary to provide for any pending claims. The Company has asserted claims against the holdback totaling $3.0 million.

Acquisition-Related Restructuring:During the first quarter of fiscal 2006, the Company finalized its
Snap Appliance integration plan to eliminate certain duplicative resources, including severance and benefits in connection with the involuntary termination of approximately 24 employees, exiting
duplicative facilities and disposing of duplicative assets. The acquisition-related restructuring liabilities were accounted for under EITF No. 95-3 and therefore were included in
the purchase price allocation. The Company recorded a total liability of $6.7 million for these activities, of which the original estimate of $6.0 million was recorded in the second
quarter of fiscal 2005 and adjustments were recorded in each subsequent quarter through the first quarter of fiscal 2006 totaling $0.7 million. Any further changes to the Company's finalized
plan will be accounted for under SFAS No. 146 and will be recorded in "Discontinued operations, net of taxes" in the Consolidated Statements of Operations. In the third quarter of fiscal 2006,
the Company recorded additional adjustments of $0.2 million due to additional lease costs related to the estimated loss of facilities that the Company subleased. As of March 31, 2006,
the Company had utilized $4.4 million of these charges. The Company anticipates that the remaining restructuring reserve balance of $2.5 million will be paid out by the third quarter of
fiscal 2012, primarily related to long-term facility leases.

The
activity in the accrued restructuring reserve related to the Snap Appliance acquisition-related restructuring plan was as follows for fiscal 2006:

Eurologic:On April 2, 2003, the Company completed the acquisition of Eurologic, a provider of external and networked
storage products. The Company acquired Eurologic to further enhance its direct-attached and fibre-attached server storage capabilities by allowing it to provide end-to-end
block- and file-based networked storage products. As consideration for the acquisition of all of the outstanding capital stock of Eurologic, the Company paid $25.6 million in cash,
subject to a Holdback as described below, and assumed stock options to purchase 0.5 million shares of the Company's common stock, with a fair value of $1.6 million. The Company also
incurred $1.1 million in transaction fees, including legal, valuation and

F-46

accounting
fees. The assumed stock options were valued using the Black-Scholes valuation model with the following assumptions: volatility rate ranging from 57% to 81%; a risk-free interest
rate ranging from 1.1% to 2.5%; and an estimated life ranging from 0.08 to 4 years.

Holdback:As part of the Eurologic purchase agreement, $3.8 million of the cash payment was
held back (the "Holdback") for unknown liabilities that may have existed as of the acquisition date. The Holdback, which was included as part of the purchase price, was included in "Accrued
liabilities" in the Consolidated Balance Sheet as of March 31, 2005 and was to be paid to the former Eurologic stockholders 18 months after the acquisition closing date, except for funds
necessary to provide for any pending claims. The Company paid $2.3 million of the Holdback as of March 31, 2005 and has asserted claims against the remaining amount for liabilities of
which it became aware following the consummation of the transaction. The former Eurologic stockholders have disputed these claims and have requested release of the remaining Holdback.

Earn-out Payments:The Company also agreed to pay the stockholders of Eurologic
contingent consideration of up to $10.0 million in cash if certain revenue levels were achieved by the acquired Eurologic business in the period from July 1, 2003 through June 30,
2004. The milestone to achieve the contingent consideration was not attained as of June 30, 2004. As a result, no additional payments were made to the former stockholders of Eurologic.

The
allocation of the Eurologic purchase price to the tangible and identifiable intangible assets acquired and liabilities assumed is summarized below (in thousands). The allocation was
based on management's estimates of fair value, which included an independent appraisal.

The
other intangible assets are being amortized over periods which reflect the pattern in which the economic benefits of the assets are expected to be realized. The core technology and
customer relationships are being amortized over an estimated useful life of four years, the trade name and covenants-not-to-compete are being amortized over two
years and the current backlog was fully amortized in the first quarter of fiscal 2004. The estimated weighted average useful life of other intangible assets, created as a result of the acquisition of
Eurologic, is approximately three years. No residual value is estimated for the other intangible assets.

Acquisition-Related Restructuring:During the fourth quarter of fiscal 2004, the Company finalized
its plans to integrate the Eurologic operations. The integration plan included the involuntary termination or relocation of approximately 110 employees, exiting duplicative facilities and the
transition of all manufacturing operations from Dublin, Ireland to the Company's manufacturing facility in Singapore. The consolidation of the manufacturing operations as well as involuntary employee
terminations was completed in the fourth quarter of fiscal 2004. The acquisition-related restructuring liabilities were accounted for under EITF No. 95-3 and therefore were included
in the purchase price allocation of the cost to acquire Eurologic. The Company recorded a liability of $3.3 million in fiscal 2004 for these activities. As of December 31, 2004, the
Company utilized approximately all of these charges and the plan is materially complete.

ICP Vortex:On June 5, 2003, the Company completed the acquisition of ICP vortex. ICP vortex was a wholly-owned
subsidiary of Intel Corporation and provided a broad range of hardware and software RAID data protection products, including SCSI, SATA and fibre channel products. The final purchase price was
$14.5 million in cash, which included $0.3 million in transaction fees, consisting of legal, valuation and accounting fees. This purchase price included a final adjustment of
$0.1 million in the first quarter of fiscal 2005 to both goodwill and acquisitions costs.

The
other intangible assets are being amortized over periods which reflect the pattern in which the economic benefits of the assets are expected to be realized. The core technology and
trade name are
being amortized straight-line over an estimated useful life of three years, the customer relationships are being amortized straight-line over four years and the royalties were
amortized through the end of the third quarter of 2004. The estimated weighted average useful life of other intangible assets, created as a result of the acquisition of ICP vortex, is approximately
three years. No residual value is estimated for the other intangible assets.

During
the first quarter of fiscal 2005, the Company finalized its plans to integrate the ICP vortex operations. The integration plan included the involuntary termination of 19
employees, the transfer of manufacturing operations to Singapore and the integration of certain duplicative resources. The acquisition-related restructuring liabilities were accounted for under EITF
No. 95-3 and therefore were included in the purchase price allocation of the cost to acquire ICP vortex. In fiscal 2004, the Company recorded a liability of $0.4 million for
severance and benefits, of which $0.3 million of these charges were

and $0.1 million was recorded as a reduction to the restructuring liability with a corresponding decrease to goodwill in the first quarter of fiscal 2005.

Elipsan:On February 13, 2004, the Company completed the acquisition of Elipsan, a provider of networked storage
infrastructure software. The Company acquired Elipsan's storage virtualization technology to enable the Company to make storage more cost-effective, easier to scale and to increase
performance across multiple RAID subsystems. The final purchase price was $19.4 million in cash, which included $0.7 million in transaction fees, consisting of legal, valuation and
accounting fees. This purchase price included a final adjustment of $0.8 million in fiscal 2005, primarily related to the reversal of the acquisition-related restructuring reserves of
approximately $0.7 million.

Holdback:As part of the Elipsan purchase agreement, $2.0 million of the cash payment was held
back ("Elipsan Holdback") for unknown liabilities that may have existed as of the acquisition date. The Elipsan Holdback, which was included as part of the purchase price, was included in "Accrued
liabilities" in the Consolidated Balance Sheet as of March 31, 2005. The Elipsan Holdback of $2.0 million was paid in the second quarter of fiscal 2006.

The

of employees and, accordingly, the Company recorded a $0.8 million reserve as of March 31, 2004. In fiscal 2005, the Company recorded an adjustment of $0.7 million as a
reduction to the liability with a corresponding decrease to goodwill as the Company intends to retain these employees. The acquisition-related restructuring liabilities were accounted for under EITF
No. 95-3 and therefore were included in the purchase price allocation of the cost to acquire Elipsan. As of March 31, 2005, the Company made payments of approximately $25,000
under the plan. The Company anticipates that the remaining restructuring reserve balance of approximately $45,000 will be paid out by the second quarter of fiscal 2007.

In-process Technology

As part of the purchase agreements of Snap Appliance, the IBM i/p Series RAID business, Eurologic and Elipsan, certain amounts of the purchase prices were
allocated to acquired in-process technology which were determined through established valuation techniques in the high-technology computer industry and written off in the
second quarter of fiscal 2005, first quarter of fiscal 2005, first quarter of fiscal 2004 and fourth quarter of fiscal 2004, respectively, because technological feasibility had not been established
and no alternative future uses existed. The values were determined by estimating the net cash flows and discounting the estimated net cash flows to their present values. A summary of the amounts
written off were as follows:

The
net cash flows from the identified projects were based on estimates of revenues, cost of revenues, research and development expenses, including costs to complete the projects,
selling, marketing and administrative expenses, royalty expenses and income taxes from the projects. The Company believes the assumptions used in the valuations were reasonable at the time of the
acquisitions. The estimated net revenues and gross margins were based on management's projections of the projects and were in line with industry averages. Estimated total net revenues from the
projects of Snap Appliance, the IBM i/p Series RAID business, Eurologic and Elipsan were expected to grow through fiscal 2009, fiscal 2009, fiscal 2008 and fiscal 2007, respectively, and decline
thereafter as other new products are expected to become available. Estimated operating expenses included research and development expenses and selling, marketing and administrative expenses based upon
historical and expected direct expense levels and general industry metrics. Estimated research and development expenses included costs to bring the projects to technological feasibility and costs
associated with activities undertaken to correct errors or keep products updated with current information (also referred to as "maintenance" research and development) after a product is available for
general release to customers. These activities range from 0% to 5% of net revenues for the in-process technologies.

The
effective tax rate used in the analysis of the in-process technologies reflects a combined historical industry specific average for the United States Federal and state
statutory income tax rates. The cost of capital reflects the estimated time to complete the projects and the level of risk involved. The following discount rates were used in computing the present
value of net cash flows for the acquired companies: approximately 24% for Snap Appliance, between 23% and 28% for the IBM i/p Series RAID business, approximately 27% for Eurologic and approximately
63% for Elipsan.

The
percentage of completion was determined using costs incurred by Snap Appliance, the IBM i/p Series RAID business, Eurologic and Elipsan prior to their respective acquisition dates
compared to the estimated remaining research and development to be completed to bring the projects to technological feasibility. The Company estimated, as of the respective acquisition dates for, Snap
Appliance, the IBM i/p Series RAID business, Eurologic and Elipsan, that the projects were approximately 25% complete, 50% complete, 60% complete and 28% complete, respectively. All projects
outstanding as of the acquisition dates for Snap Appliance, Eurologic and Elipsan were completed as of September 30, 2005, March 31, 2004 and December 31, 2004, respectively. All
projects outstanding as of the acquisition date for the IBM i/p Series RAID business ceased as of September 30, 2005 with the sale of the business.

The
pro forma financial information for fiscal 2006 has not been disclosed as the acquisitions of the IBM i/p Series RAID business and Snap Appliance were included as part of
discontinued operations.

Platys:In connection with the Platys Communications, Inc. ("Platys") acquisition in August 2001,
$15.0 million of the cash payment was held back (the "General Holdback") for unknown liabilities that may have existed as of the acquisition date. In fiscal 2003 and fiscal 2004, the Company
paid $10.7 million and $3.6 million, respectively, of the General Holdback to the former Platys shareholders or for the settlement of certain claims on their behalf. The remaining
$0.7 million of the General Holdback will be paid to the Platys shareholders by the second quarter of fiscal 2007.

In
fiscal years 2005 and 2004, the Company recorded reductions of $0.4 million and $1.3 million, respectively, of deferred stock-based compensation related to cancellations
of assumed Platys stock options that were unvested and repurchases of unvested Platys restricted stock. In fiscal years 2005 and 2004, the Consolidated Statement of Operations included stock-based
compensation expense with respect to the

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To
the Board of Directors and Stockholders
of Adaptec, Inc.

We
have completed integrated audits of Adaptec, Inc.'s 2006 and 2005 consolidated financial statements and of its internal control over financial reporting as of March 31,
2006, and an audit of its 2004 consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Our opinions, based on our audits,
are presented below.

Consolidated financial statements and financial statement schedule

In our opinion, the consolidated financial statements listed in the index appearing under Item 15(a)(1) present fairly, in all material respects, the financial
position of Adaptec, Inc. and its subsidiaries at March 31, 2006 and 2005, and the results of their operations and their cash flows for each of the three years in the period ended
March 31, 2006 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule appearing under Item
15(a)(2) presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. These financial statements and
financial statement schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements and financial statement schedule based on our
audits. We conducted our audits of these statements 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. An audit of financial statements includes 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. We believe that our audits provide a reasonable basis for our opinion.

Internal control over financial reporting

Also, in our opinion, management's assessment, included in management's Report on Internal Control Over Financial Reporting appearing under Item 9A, that the
Company maintained effective internal control over financial reporting as of March 31, 2006 based on criteria established in Internal ControlIntegrated Framework issued by the
Committee of Sponsoring Organizations of the Treadway Commission (COSO), is fairly stated, in all material respects, based on those criteria. Furthermore, in our opinion, the Company maintained, in
all material respects, effective internal control over financial reporting as of March 31, 2006, based on criteria established in Internal ControlIntegrated Framework issued by the
COSO. The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial
reporting. Our responsibility is to express opinions on management's assessment and on the effectiveness of the Company's internal control over financial reporting based on our audit. We conducted our
audit of internal control over financial reporting in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. An audit of internal control over financial
reporting includes obtaining an understanding of internal control over financial reporting, evaluating management's assessment, testing and evaluating the design and operating effectiveness of
internal control, and performing such other procedures as we consider necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinions.

A
company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of
financial statements for

F-59

---



external
purposes in accordance with generally accepted accounting principles. A company's 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 the assets of the company; (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 receipts and expenditures of the company are
being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized
acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

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