PART I ITEM 1. BUSINESS OVERVIEW Network Appliance, Inc. (the "Company" or "Network Appliance") designs, manufactures, markets and supports high performance network data storage devices which provide fast, simple, reliable and cost effective file service for data-intensive network environments. The Company pioneered the concept of the "network appliance," an extension of the industry trend towards dedicated, specialized devices which perform a single function in the network, similar to the adoption of the router for network communications management. The Company's products consist of network data storage appliances or "filers" and proxy caching solutions developed to address the specific market requirements of data-intensive network environments as well as the World Wide Web. The Company's filers utilize an efficient software kernel optimized to exclusively perform the file service task. Unlike previous file server approaches, these products are not burdened by a general purpose operating system or file system overhead. By using a proprietary software architecture, Network Appliance is able to use industry standard hardware components rather than specialized hardware. The Company's filer products combine specialized proprietary software and state-of-the-art industry standard hardware to provide a unique solution for the NFS, Common Internet File System ("CIFS"), and HTTP server markets. PRODUCTS Filers -- The Company offers data access appliances or filers which cover a broad range of needs. Current products include the NetApp(R) F210, an entry-level appliance targeted for small workgroups and branch offices, the NetApp F230 workgroup filer, the NetApp F520, designed to address the needs of large departments, and the enterprise-class NetApp F630. All filers are based on a PCI-bus architecture and come packaged in rack mountable enclosures. The NetApp F210 and F230 filers are based on Pentium(R) processors and utilize SCSI-based storage. The NetApp F520 and NetApp F630 are based on Digital's Alpha(R) processor and support either SCSI or fibre channel arbitrated loop ("Fibre Channel") conventions as storage options. All of the Company's filers include the Data ONTAP(TM) operating system and one base or standard protocol (either NFS, CIFS or HTTP). Native multiprotocol functionality can be easily added through licensing non-base protocols at an additional cost. NetApp filer list prices range from approximately $15,000 to $600,000, depending primarily on the model purchased and the product configuration. Data ONTAP Operating System -- Combining advanced multiprotocol file system technology and a powerful microkernel-based design, the Network Appliance filer software solution, Data ONTAP, delivers simultaneous file service to UNIX, Windows and Web clients. Data ONTAP, version 5.0, supports multiple volume server partitioning, a popular strategy for modularizing, consolidating and administering data according to applications, data types and organizational needs. Proxy Caching Solutions -- NetCache(TM), the Web proxy caching software made available through the Internet Middleware Corporation ("IMC") acquisition, allows network administrators to replicate or cache Web content. This reduces bandwidth costs by avoiding duplicate requests generated over the WAN, and significantly speeds up access for users. NetCache also provides greater control and selection of information permitted over the network. The software is currently available for Windows NT, SPARC Solaris and Digital UNIX. In fiscal 1998, the Company introduced a family of network cache appliances. NetCache appliances and software allow carriers, ISPs and corporations to reduce network traffic, significantly improve user response time and enhance security. The NetApp C230 is a dedicated caching appliance designed for small points of presence ("POPs") and remote offices where there are no system administrators present. The NetApp C630, supporting access times up to T3, is a high-performance appliance, suitable for large corporate installations and ISP data centers. 2 3 SALES AND MARKETING Network Appliance has established multiple distribution channels to accelerate market penetration of its products. The Company initially marketed its products primarily through indirect sales channels both domestically and internationally. In fiscal 1995, the Company shifted its emphasis domestically to direct sales and significantly expanded its direct sales force. The Company continues to rely primarily on indirect sales in Asia and in some portions of Europe. Network Appliance has approximately 25 sales offices located within North America and 6 sales offices within Europe and Asia. No customers accounted for 10% or more of the Company's net sales in fiscal 1998, 1997 or 1996. BACKLOG The Company manufactures its products based upon forecast of customers' demand. Orders are generally placed by customers on an as-needed basis and products are typically shipped within one to four weeks following receipt of an order. In general, customers may cancel or reschedule orders without penalty. For these reasons, the Company does not believe "orders" constitute a firm "backlog" and believes it is not a meaningful indicator of revenues nor material to an understanding of its business. CUSTOMER SERVICE AND SUPPORT Network Appliance's customer service and support organization provides customers with technical support, education and training. Network Appliance believes that providing a high level of customer service and technical support is critical to customer satisfaction and the Company's success. Warranty coverage includes 24 hour telephone support plus advanced replacement of defective hardware shipped on a next business day basis. For an additional charge, the Company also offers upgraded service during the warranty period, providing for faster on-site hardware repair. The standard hardware warranty for most parts includes one year of part replacement for failed components. Software support, including the repair of errors or defects, and new release updates are provided at no extra charge for 90 days after product shipment. Support for software is available beyond the initial period through the software subscription program. Post-warranty service programs include: cooperative maintenance wherein the customer purchases replacements or extra parts and performs self-maintenance tasks, a full-service program involving a combination of telephone-based support and on-site advanced replacement, and a software subscription program that includes telephone support and software upgrades. The Company charges for service programs on an annual subscription basis, with discounts to sites with multiple filers. On-site support is primarily provided by independent parties both in North America and internationally. MANUFACTURING Network Appliance's manufacturing operations, located in Santa Clara, California, consist of procurement of materials, commodity management, component engineering, manufacturing engineering, product assembly, product assurance, quality control and final test. Network Appliance relies on many suppliers for the procurement of materials, as well as several key subcontractors for the production of certain board level assemblies. The Company's manufacturing strategy has been to develop close relationships with its suppliers, exchanging critical information and implementing joint quality training programs. This manufacturing strategy minimizes capital investment and overhead expenditures and creates flexibility by providing the capacity for rapid expansion. During May 1997, Network Appliance was awarded the ISO 9001 certification. The Company relies upon a limited number of suppliers of several key components utilized in the assembly of the Company's products. The Company procures disk drives from multiple sources. However, the Company purchases most of its disk drives through a single supplier. The Company purchases computer boards and microprocessors from a limited number of suppliers. The Company's reliance on its suppliers involves several risks, including a potential inability to obtain an adequate supply of required components, price increases, timely delivery and component quality. This risk is particularly significant with respect to the Company's supplier of disk drives because in order to meet product performance requirements, the Company must obtain disk drives of extremely high quality and capacity. In addition, there are periodic supply and 3 4 demand issues for disk drives, microprocessors and for semiconductor memory components, which could result in component shortages, selective supply allocations and increased prices of such components. Although to date the Company has been able to purchase its requirements of such components, there is no assurance that the Company will be able to obtain its full requirements of such components in the future or that prices of such components will not increase. In addition, there can be no assurance that problems with respect to yield and quality of such components and timeliness of deliveries will not occur. Disruption or termination of the supply of these components could delay shipments of the Company's products and could have a material adverse effect on the Company's business, operating results, financial condition or cash flows. Such delays could also damage relationships with current and prospective customers. Certain of the Company's resellers and end-users have historically purchased minimally configured systems from the Company and have sourced additional disk drives and memory components from other vendors. Since these components do not undergo the Company's rigorous sourcing and testing procedures, they may experience more failures and incompatabilities when deployed in the Company's products. Any such higher failure rate or incompatabilities could negatively impact the Company's reputation and, as a result, could materially adversely affect its business, operating results, financial condition or cash flows. RESEARCH AND DEVELOPMENT Since its inception, Network Appliance has made substantial investments in research and development. Network Appliance believes that its future performance will depend in large part on its ability to maintain and enhance its current product line, develop new products that achieve market acceptance, maintain technological competitiveness and meet an expanding range of customer requirements. The Company intends to expand its existing product offerings and to introduce new products. As part of the Company's ongoing development process, the Company introduced a significant software release during fiscal 1998 -- Data ONTAP release 5.0. The Company also initiated production shipments of its NetApp C230 and NetApp C630 NetCache appliances. In November 1997, the Company released version 2.0 of its NetApp Windows Networking Software, featuring SecureShare(TM). SecureShare enables true file system sharing for clients based on different operating systems. Windows and UNIX clients are now able to access the same files, at the same time. The Company's future growth depends upon the success of these and other new products, however there can be no assurance that these or other new products will attain market acceptance. Due to the complexity of network file servers and the difficulty in gauging the engineering effort required to produce new products, new products are subject to significant technical risks. There can be no assurance that new products will be introduced on a timely basis or at all. In the past, the Company has experienced delays in the shipments of its new products principally due to an inability to qualify component parts from disk drive and other suppliers, resulting in delay or loss of product sales. If new products are delayed or do not achieve market acceptance, the Company's business, operating results, financial condition or cash flows will be materially adversely affected. The network file server market is characterized by rapid technological change, changing customer needs, frequent new product introductions and evolving industry standards. The introduction of products embodying new technologies and the emergence of new industry standards could render the Company's existing products obsolete and unmarketable. The Company's future success will depend upon its ability to develop and introduce new products (including new software releases and enhancements) on a timely basis that keep pace with technological developments and emerging industry standards and address the increasingly sophisticated needs of its customers. There can be no assurance that the Company will be successful in developing and marketing new products that respond to technological changes or evolving industry standards, that the Company will not experience difficulties that could delay or prevent the successful development, introduction and marketing of new products, or that its new products will adequately meet the requirements of the marketplace and achieve market acceptance. If the Company is unable, for technological or other reasons, to develop and introduce new products in a timely manner in response to changing market conditions or customer 4 5 requirements, the Company's business, operating results, financial condition or cash flows will be materially adversely affected. Network file server products like those offered by the Company may contain undetected software errors or failures when first introduced or as new versions are released. There can be no assurance that, despite testing by the Company and by current and potential customers, errors will not be found in new products after commencement of commercial shipments, resulting in loss of or delay in market acceptance, which could have a material adverse effect upon the Company's business, operating results, financial condition or cash flows. The Company's total expenses for research and development for fiscal years 1998, 1997 and 1996 were $16.6 million, $9.0 million and $4.8 million, respectively. The Company anticipates that research and development expenses will increase in absolute dollars in future periods. COMPETITION The network file server market is intensely competitive and characterized by rapidly changing technology. The Company experiences substantial competition from specialized network file server companies, such as Auspex Systems, Inc. The Company also competes against traditional suppliers of UNIX-based systems that are used as network file servers including Sun Microsystems, Digital Equipment Corporation, Hewlett-Packard Company, EMC (indirectly through OEM relationships with system vendors), Silicon Graphics, Inc. and IBM Corporation, among others. In addition, certain of these large traditional suppliers of general purpose computers may in the future offer specialized file server products which are more directly competitive with those of the Company. The Company also encounters competition from manufacturers of PC-based file servers utilizing Windows NT and emerging standards. The Company's NetCache software and NetCache appliances compete against a number of software and hardware solutions, ranging from small start-ups to larger systems vendors. While the Company believes that the price-performance characteristics of its products are currently competitive, increased competition is likely to result in price reductions, reduced gross margin and loss of market share, any of which could materially adversely affect the Company's business, operating results, financial condition or cash flows. Many of the Company's current and potential competitors have significantly greater financial, technical, marketing and other resources than the Company. As a result, they may be able to respond more quickly to new or emerging technologies and changes in customer requirements, or devote greater resources to the development, promotion, sale and support of their products than the Company. In addition, current and potential competitors have established or may establish cooperative relationships among themselves or with third parties. Accordingly, it is possible that new competitors or alliances among competitors may emerge and rapidly acquire significant market share. In addition, the Company derives a significant portion of its sales from the resale of disk drives as components of its filers and therefore experiences competition from disk drive resellers. The market for the resale of disk drives is highly competitive and subject to intense price pressures. There can be no assurance that the Company will be able to compete successfully against current or future competitors or that competitive pressures faced by the Company will not materially adversely affect its business, operating results, financial condition or cash flows. The Company believes that the principal competitive factors affecting its market include product features such as response time, scalability and ease of use, price, multiprotocol capabilities and customer service and support. Although the Company believes that its products currently compete favorably with respect to these factors, there can be no assurance that the Company can maintain its competitive position against current and potential competitors, especially those with significantly greater financial, marketing, service, support, technical and other resources. PROPRIETARY RIGHTS Network Appliance's success depends significantly upon its proprietary technology. The Company currently relies on a combination of copyright and trademark laws, trade secrets, confidentiality procedures and contractual provisions to protect its proprietary rights. The Company seeks to protect its software, documentation and other written materials under trade secret and copyright laws, which afford only limited 5 6 protection. The Company has registered its Network Appliance name and logo, FAServer and NetApp trademarks. The Company will continue to evaluate the registration of additional trademarks as appropriate. The Company generally enters into confidentiality agreements with its employees and with its resellers and customers. The Company currently has multiple U.S. and international patent applications pending. There can be no assurance that the pending applications will be approved, or that if issued, such patents will not be challenged, and if such challenges are brought, that such patents will not be invalidated. There can be no assurance that the Company will develop proprietary products or technologies that are patentable, that any issued patent will provide the Company with any competitive advantages or will not be challenged by third parties, or that the patents of others will not have a material adverse effect on the Company's ability to do business. Litigation may be necessary to protect the Company's proprietary technology. Any such litigation may be time-consuming and costly. Despite the Company's efforts to protect its proprietary rights, unauthorized parties may attempt to copy aspects of the Company's products or to obtain and use information that the Company regards as proprietary. In addition, the laws of some foreign countries do not protect proprietary rights to as great an extent as do the laws of the United States. There can be no assurance that the Company's means of protecting its proprietary rights will be adequate or that the Company's competitors will not independently develop similar technology, duplicate the Company's products or design around patents issued to the Company or other intellectual property rights of the Company. There have also been substantial amounts of litigation in the computer industry regarding intellectual property rights. In the first quarter of fiscal 1997, the Company settled litigation related to the alleged infringement of third party rights and other claims, which resulted in the Company recording a pre-tax expense of $4.3 million ($3.5 million in payments to the plaintiffs and $0.8 million in legal fees). In addition, the Company may from time to time receive claims that it is infringing third parties' intellectual property rights. There can be no assurance that third parties will not in the future claim infringement by the Company with respect to current or future products, trademarks or other proprietary rights. The Company expects that companies in the file server market will increasingly be subject to infringement claims as the number of products and competitors in the Company's industry segment grows and the functionality of products in different industry segments overlaps. Any such claims could be time-consuming, result in costly litigation, cause product shipment delays, require the Company to redesign its products or require the Company to enter into royalty or licensing agreements, any of which could have a material adverse effect upon the Company's business, operating results, financial condition or cash flows. Such royalty or licensing agreements, if required, may not be available on terms acceptable to the Company or at all. EMPLOYEES As of May 31, 1998, Network Appliance had a total of approximately 450 employees. Of the total, 247 were in sales and marketing, 116 in research and development, 45 in finance and administration and 42 in operations. The Company's future performance also depends in significant part upon the continued service of its key technical and senior management personnel, none of whom is bound by an employment agreement. The Company has not experienced any work stoppages and considers its relations with its employees to be good. 6 7 EXECUTIVE OFFICERS The executive officers of the Company, and their ages as of May 31, 1998, are as follows:

OTHER FACTORS AFFECTING THE COMPANY History of Operating Losses; Potential Fluctuations in Quarterly Results -- The Company was organized in April 1992 and first shipped products in June 1993. While the Company generated net income in fiscal 7 8 1998, 1997 and 1996, it incurred significant losses in fiscal 1995 and in each of its prior fiscal years. There can be no assurance that the Company will remain profitable on a quarterly or annual basis. The Company's quarterly operating results have in the past varied and may in the future vary significantly depending on a number of factors, including: the level of competition; the size, timing and cancellation of significant orders; product configuration and mix; market acceptance of new products and product enhancements; new product announcements or introductions by the Company or its competitors; deferrals of customer orders in anticipation of new products or product enhancements; changes in pricing by the Company or its competitors; the ability of the Company to develop, introduce and market new products and product enhancements on a timely basis; hardware component costs; supply constraints; the Company's success in expanding its sales and marketing programs; technological changes in the network file server market; the mix of sales among the Company's sales channels; levels of expenditure on research and development; changes in Company strategy; personnel changes; general economic trends and other factors. Sales for any future quarter are not predictable with any significant degree of certainty. The Company generally operates with limited order backlog because its products typically are shipped shortly after orders are received. As a result, product sales in any quarter are generally dependent on orders booked and shipped in that quarter. Product sales are also difficult to forecast because the network file server market is rapidly evolving and the Company's sales cycle varies substantially from customer to customer. A significant portion of the Company's revenues in any quarter may be derived from sales to a limited number of customers. Any significant deferral of these sales could have a material adverse effect on the Company's results of operations in any particular quarter; and to the extent that significant sales occur earlier than expected, operating results for subsequent quarters may be adversely affected. Because Company expense levels are based, in part, on its expectations as to future sales and because a significant percentage of the Company's expenses are fixed, if sales levels are below expectations, net income may be disproportionately affected. Although the Company has experienced significant revenue growth in recent periods, such growth may not be indicative of future operating results. Period-to-period comparisons of its results of operations are not necessarily meaningful and should not be relied upon as an indicator of future performance. Due to all of the foregoing factors, it is possible that in some future quarter the Company's operating results may be below the expectations of public market analysts and investors. In such event, the price of the Company's common stock would likely be materially adversely affected. Dependence on Growth in the Network File Server Market -- All of the Company's filer products address the network file server market. The Company's future financial performance will depend in large part on continued growth in the network file server market and on emerging standards in this market. There can be no assurance that the market for network file servers will continue to grow or that emerging standards in the network file server market will not adversely affect the growth of the NFS and Windows NT servers. If the network file server market fails to grow, grows more slowly than anticipated, or if network file servers, based on emerging standards other than those adopted by the Company, become increasingly accepted by the market, the Company's business, operating results, financial condition or cash flows could be materially adversely affected. During recent years, segments of the computer industry have experienced significant economic downturns characterized by decreased product demand, production overcapacity, price erosion, work slowdowns and layoffs. The Company's operations may in the future experience substantial fluctuations from period-to-period as a consequence of such industry patterns, general economic conditions affecting the timing of orders from major customers and other factors affecting capital spending. There can be no assurance that such factors will not have a material adverse effect on the Company's business, operating results, financial condition or cash flows. International Operations -- The Company conducts business internationally. Accordingly, the Company's future operating results could be materially adversely affected by a variety of uncontrollable and changing factors including regulatory, political or economic conditions in a specific country or region, trade protection measures and other regulatory requirements and government spending patterns. The Company's international sales are denominated in U.S. dollars and in foreign currencies. An increase in the value of the U.S. dollar relative to foreign currencies could make the Company's products more 8 9 expensive and, therefore, potentially less competitive in those markets. For international sales denominated in foreign currencies, the Company is subject to risks associated with currency fluctuations. Additional risks, among others, inherent in the Company's international business activities generally include longer accounts receivable payment cycles, difficulties in managing international operations and potentially adverse tax consequences. There can be no assurance that such factors will not have a material adverse effect on the Company's future international sales and, consequently, the Company's business, operating results, financial condition or cash flows. Although operating results have not been materially adversely affected by seasonality in the past, because of the significant seasonal effects experienced within the industry, particularly in Europe, there can be no assurance that the Company's future operating results will not be adversely affected by seasonality. The Company believes that its continued growth and profitability will require successful expansion of its international operations and sales and therefore the Company has committed significant resources to such expansion. In order to successfully expand international sales in fiscal 1999 and subsequent periods, the Company must strengthen foreign operations, hire additional personnel and recruit additional international distributors and resellers. This will require significant management attention and financial resources and could materially adversely affect the Company's business, operating results, financial condition or cash flows. To the extent that the Company is unable to effect these additions in a timely manner, the Company's growth, if any, in international sales will be limited, and the Company's business, operating results, financial condition or cash flows could be materially adversely affected. In addition, there can be no assurance that the Company will be able to maintain or increase international market demand for the Company's products. The Company currently sells a significant portion of its products internationally through resellers. There can be no assurance that any of the Company's international resellers or customers will continue to distribute or purchase the Company's products. Product Concentration; Changing Product Mix -- The Company derives a substantial portion of its revenues from the sale of its network filer product line. As a result, a reduction in the demand for filer products due to increased competition, a general decline in the market for network file servers or other factors would have a material adverse effect on the Company's business, operating results, financial condition or cash flows. In fiscal 1998, the Company introduced four new filers: the NetApp F210, NetApp F230, NetApp F520 and NetApp F630. Additional product introductions in future periods are expected to impact the sales of existing products. If the Company is unable to introduce new products in a timely manner, effectively manage the introduction of new products and any related inventory transitions or if such products do not achieve market acceptance, the Company's business, operating results, financial condition or cash flows could be materially adversely affected. Concentration of Sales -- Historically, a significant portion of the Company's sales have been made to a limited number of end user customers and resellers. In fiscal 1998, 1997 and 1996, no customers accounted for 10% or more of net sales. The Company generally has not entered into long term volume purchase contracts with its end user customers or resellers, and such end user customers or resellers may have certain rights to extend or delay the shipment of their orders. The loss of a major end user customer or reseller, the reduction, delay or cancellation of orders or a delay in shipment of the Company's products to such end user customer or reseller could materially adversely affect the Company's business, operating results and financial condition. In addition, should one or more of these resellers choose to promote products competitive with the Company's products, the Company's business, operating results, financial condition or cash flows could be materially adversely affected. Dependence Upon Key Personnel -- The Company's continued growth and success depends to a significant extent on the continued service of senior management and other key employees and the hiring of additional qualified employees. Competition for highly-skilled personnel is intense in the high technology industry. There can be no assurance that the Company will be successful in recruiting new personnel or in retaining existing personnel. The loss of one or more key employees or the Company's inability to attract additional qualified employees or retain other employees could have a material adverse effect on the Company's business, results of operations, financial condition or cash flows. 9 10 Management of Expanding Operations -- The Company has a history of rapid growth. The Company's future operating results will depend to a large extent on management's ability to successfully manage expansion and growth, including but not limited to hiring and retaining significant numbers of qualified technical, sales and other employees, expanding international operations, forecasting revenues, addressing new markets, controlling expenses, implementing infrastructure and systems and managing its assets. An unexpected decline in the growth rate of revenues without a corresponding and timely reduction in expense growth or a failure to manage other aspects of growth could have a material adverse effect on the Company's business, results of operations, financial condition or cash flows. Possible Volatility of Stock Price -- The trading price of the Company's common stock could be subject to wide fluctuations in response to a number of factors, including quarterly variations in operating results, announcements of technological innovations or new products, applications or product enhancements by the Company or its competitors, changes in financial estimates by securities analysts and other events. In addition, the stock market has experienced volatility that has particularly affected the market prices of equity securities of many high technology companies and that often has been unrelated or disproportionate to the operating performance of such companies. These broad market fluctuations may adversely affect the market price of the Company's common stock. Effect of Certain Charter Provisions; Anti-takeover Effects of Provisions of the Bylaws -- The Company's Board of Directors has the authority to issue up to 5,000,000 shares of preferred stock and to determine the price, rights, preferences, privileges and restrictions, including voting rights, of those shares without any further vote or action by the shareholders. The rights of the holders of common stock will be subject to, and may be adversely affected by, the rights of the holders of any preferred stock that may be issued in the future. The issuance of preferred stock could have the effect of making it more difficult for a third party to acquire a majority of the outstanding voting stock of the Company. Further, certain provisions of the Company's bylaws pertaining to the future elimination of cumulative voting and shareholder action by written consent, and the requirement that shareholders may call a special meeting of shareholders only upon a request of shareholders owning at least 50% of the Company's common stock, could delay or make more difficult a proxy contest involving the Company, which could adversely affect the market price of the Company's common stock. Year 2000 Issues -- The "Year 2000 Issue" refers to computer programs which use two digits rather than four to define a given year and which therefore might read a date using "00" as the year 1900 rather than the year 2000. The Company is currently assessing the impact the Year 2000 Issue will have on its internal information systems. The Company believes that the majority of its current products are Year 2000 compliant and that new products are being designed to be Year 2000 compliant. The Company is currently performing extended testing. The Company does not anticipate that addressing the Year 2000 Issue for its internal information systems and current and future products will have a material adverse impact on its operations, financial results or cash flows. However, there can be no assurance that these costs will not be greater than anticipated, or that corrective actions undertaken will be completed before any Year 2000 problems could occur. The Year 2000 Issue could lower demand for the Company's products while increasing the Company's costs. These combining factors, while not quantified, could have a material adverse impact on the Company's business, operating results, financial condition or cash flows. The Company has key relationships with suppliers. If these suppliers fail to adequately address the Year 2000 Issue for the products they provide the Company, this could have a material adverse impact on the Company's business, operating results, financial condition or cash flows. The Company is still assessing the effect the Year 2000 Issue will have on its suppliers and, at this time, cannot determine the impact it will have. ITEM 2. PROPERTIES Network Appliance's principal administrative, sales, marketing, manufacturing and research and development facility is located in approximately 120,000 square feet of space in Santa Clara, California. This facility is leased under various operating leases which expire through fiscal 2003. The Company leases other sales offices throughout the U.S. and in Europe. The Company believes that the existing facilities are adequate for its current needs and that additional space will be available as needed. See additional discussion regarding 10 11 properties in "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations -- Liquidity and Capital Resources." ITEM 3. LEGAL PROCEEDINGS None. ITEM 4. SUBMISSIONS OF MATTERS TO A VOTE OF SECURITY HOLDERS No matters were submitted to a vote of security holders during the fourth quarter of the fiscal year covered by this Annual Report on Form 10-K. PART II ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED SHAREHOLDER MATTERS The Company's common stock commenced trading on the Nasdaq National Market on November 21, 1995 and is traded under the symbol "NTAP." As of May 31, 1998, there were 284 holders of record of the common stock and 6,667 beneficial owners. The following table sets forth for the periods indicated the high and low closing sale prices for the common stock as reported on the Nasdaq National Market, adjusted to reflect the effect of the December 17, 1997 two-for-one stock split.

The Company believes that a number of factors, including, but not limited to, quarterly variations in results of operations may cause the market price of its common stock to fluctuate significantly. See "Item 1. Business -- Other Factors Affecting the Company." The Company has never paid cash dividends on its capital stock. The Company currently anticipates that it will retain all available funds for use in its business and does not anticipate paying any cash dividends. ITEM 6.

FISCAL 1998 COMPARED TO FISCAL 1997 Net Sales -- Net sales increased to $166.2 million in fiscal 1998 from $93.3 million in fiscal 1997, an increase of 78.0%. The increase in net sales was principally attributable to a higher volume of filers shipped. The increase in unit shipments resulted primarily from the Company's expansion of its direct sales force and the introduction of new products during June and July 1997, particularly the enterprise-class NetApp F630, the NetApp F520 and the NetApp F230. Net sales for fiscal 1998 were also positively impacted by a shift in product mix toward higher-end systems, primarily due to the introduction of new products, leading to higher average selling prices for filers than in the previous fiscal year. Net sales also grew as a result of increased multiprotocol system shipments, the licensing of multiprotocol software to pre-existing customers and increased service and software subscription revenues due to a growing installed base. International net sales (including U.S. exports) were $37.8 million and $16.1 million, for fiscal 1998 and 1997, respectively. The increase in international net sales was primarily a result of European sales growth due to increased headcount in the direct sales force over the prior fiscal year and to the introduction of the new products in June and July 1997. 12 13 There can be no assurance that the Company's net sales will continue to increase in absolute dollars or at the rate at which they have grown in recent fiscal periods. Gross Margin -- Gross margin remained relatively flat increasing slightly to 59.3% of net sales for fiscal 1998 compared to 59.2% of net sales for fiscal 1997. This increase in gross margin was primarily attributable to the increase in product volume, lower costs of key components, increased manufacturing efficiencies and by the sale of the Company's new product with cost-reduced designs first introduced in June and July 1997. Gross margin was also favorably impacted by the licensing of multiprotocol software and by growth in software subscription and service revenues due to a growing installed base. Factors contributing to gross margin growth were partially offset by the sale of 4 gigabyte drives at reduced prices in fiscal 1998. The Company's gross margin has been and will continue to be affected by a variety of factors, including competition, product configuration, direct versus indirect sales, the mix and average selling prices of products, new product introductions and enhancements and the cost of components and manufacturing labor. In particular, the Company's gross margin varies based upon the configuration of systems that are sold and whether they are sold directly or through indirect channels. Highly configured systems typically generate lower overall gross margin percentages due to greater disk drive and memory content. Sales and Marketing -- Sales and marketing expenses consist primarily of salaries, commissions, advertising and promotional expenses and customer service and support costs. Sales and marketing expenses increased 76.3% to $42.8 million in fiscal 1998, compared to $24.3 million in fiscal 1997. These expenses were 25.7% and 26.0% of net revenues for fiscal 1998 and 1997, respectively. The increase in absolute dollars was primarily related to the expansion of the Company's sales and marketing organization, including growth in the domestic and international direct sales forces and increased commission expenses. During the quarter ended January 23, 1998, the Company launched an advertising campaign which contributed to absolute dollar growth in sales and marketing expenses for fiscal 1998. The Company expects to continue to increase its sales and marketing expenses in an effort to expand domestic and international markets, introduce new products, establish and expand new distribution channels and increase product and company awareness. The Company believes that its continued growth and profitability is dependent in part on the successful expansion of its international operations, and therefore, has committed significant resources to international sales. Research and Development -- Research and development expenses consist primarily of salaries and benefits and prototype expenses. Research and development expenses increased 85.6% to $16.6 million in fiscal 1998, compared to $9.0 million in the prior fiscal year. These expenses represented 10.0% and 9.6% of net sales in fiscal 1998 and 1997, respectively, and increased as a result of headcount growth, prototyping expenses associated with the development of new products and ongoing support of current and future product development and enhancement efforts. The Company believes that significant investments in research and development will be required to remain competitive and expects that such expenditures will continue to increase in absolute dollars. General and Administrative -- General and administrative expenses were $6.5 million in fiscal 1998, compared to $4.1 million in fiscal 1997, an increase of 57.9%. These expenses represented 3.9% and 4.4% of net sales for such periods and increased in absolute dollars primarily as a result of headcount growth, increased professional services fees and an increase to the allowance for bad debt. The Company believes that its general and administrative expenses will increase in absolute dollars as the Company continues to build its infrastructure. Litigation Settlement -- See discussion in MD&A section titled "Fiscal 1997 Compared to Fiscal 1996." Purchased In-Process Technology and Related Compensation Charge -- See discussion in MD&A section titled "Fiscal 1997 Compared to Fiscal 1996." Other Income, Net -- Other income, net, was $0.9 million and $1.0 million in fiscal 1998 and 1997, respectively. Other income, net, decreased over the corresponding period of the prior year due primarily to foreign currency exchange losses recorded in fiscal 1998. 13 14 Provision for Income Taxes -- The Company's effective tax rate for fiscal 1998 was 37.5% compared to 93.8% for fiscal 1997. The fiscal 1997 tax rate was primarily affected by the one-time charge to operations of $7.4 million for the write-off of purchased in-process research and development related to the IMC acquisition which was not deductible for income tax purposes. Excluding the net effect of the IMC acquisition, the fiscal 1997 effective tax rate would have been 35%. The higher effective tax rate in fiscal 1998, compared to the fiscal 1997 effective tax rate, exclusive of the IMC acquisition, relates to increased earnings, which reduce the impact of research and development and other tax credits on the effective tax rate. Additionally, fiscal 1997 included a benefit for the reversal of a valuation allowance previously provided against deferred tax assets which did not occur in fiscal 1998. As of April 30, 1998 and 1997, a valuation allowance was deemed unnecessary as Company management determined that it is more likely than not that the net deferred tax asset is realizable. FISCAL 1997 COMPARED TO FISCAL 1996 Net Sales -- Net sales increased by 100% to $93.3 million in fiscal 1997 from $46.6 million in fiscal 1996. This increase was attributable to an increased shipping volume of filers and related peripheral devices and higher average selling prices of filers. The increase in filer shipments resulted primarily from the Company's expansion of its domestic and international direct sales force, growth of the Company's domestic and international indirect sales channel, increased market acceptance of the Company's products and the introduction of the NetApp F540. The higher average selling prices resulted primarily from the introduction of the enterprise-class NetApp F540 and the shipment of a greater number of units directly to end users, who generally purchase more highly configured systems at higher average selling prices than resellers. Net sales also increased as a result of the introduction of multiprotocol systems and the licensing of multiprotocol software to pre-existing customers. Gross Margin -- Gross margin increased to 59.2% in fiscal 1997 from 55.9% in fiscal 1996. This increase in gross margin was primarily attributable to the increase in product volume in fiscal 1997, lower costs of key components and increased manufacturing efficiencies. Gross margin also increased over the prior fiscal year as a result of licensing multiprotocol software and increases in software subscription revenue due to a larger installed base. These factors offset the effect of increased sales of highly configured systems during fiscal 1997, which generally generate lower gross margins per system due to higher disk drive content. Sales and Marketing -- Sales and marketing expenses increased 90.6% to $24.3 million in fiscal 1997 from $12.7 million in fiscal 1996. These expenses were 26.0% and 27.3% of net sales in fiscal 1997 and 1996, respectively. The increase in absolute dollars was primarily related to the expansion of the Company's sales and marketing organization, particularly the increase in the direct sales force, and increased commission expenses related to higher sales volumes. Research and Development -- Research and development expenses increased 88.3% to $9.0 million in fiscal 1997 from $4.8 million in fiscal 1996. These expenses represented 9.6% and 10.2% of net sales in fiscal 1997 and 1996, respectively, and increased in absolute dollars primarily as a result of increased headcount, prototyping expenses associated with the development of new products and the support of the current and future product development and enhancement efforts. General and Administrative -- General and administrative expenses were $4.1 million in fiscal 1997, compared to $2.6 million in fiscal 1996, an increase of 60.4%. These expenses represented 4.4% and 5.5%, respectively, of net sales for such periods. In fiscal 1997, the Company continued its investments in additional staffing, facilities expansion and related occupancy costs necessary to manage and support the Company's growth. Professional fees also increased from fiscal 1996 to fiscal 1997. The growth in professional fees was primarily related to increases in general legal fees, investor relation activities and accounting related services. Purchased In-Process Technology and Related Compensation Charge -- On March 17, 1997, the Company acquired all outstanding shares and options to purchase shares of IMC common stock by issuing 374,046 shares of the Company's common stock and options to purchase shares of the Company's common stock. In connection with the acquisition, intangible assets of $8.4 million were acquired, of which $7.4 million 14 15 was reflected as a one-time charge to operations for the write-off of in-process research and development that had not reached technological feasibility and, in management's opinion, had no probable alternative future use. The remaining intangible assets of $1.0 million, consisting of existing technology and goodwill, are included in other assets in the accompanying consolidated balance sheets and are being amortized over their estimated useful lives of five years. Certain key employees of IMC who continued as employees of the Company were also granted vested options to purchase shares of the Company's common stock at a discount to the market price of the Company's common stock immediately preceding the acquisition. In connection with the granting of these options, the Company recorded a compensation charge of $3.2 million in the fourth quarter of fiscal 1997. The acquisition was accounted for as a purchase and, accordingly, the results of operations of IMC from the date of acquisition forward have been included in the Company's consolidated financial statements. IMC results of operations included in the Company's consolidated financial statements for fiscal 1997 were not significant. See Note 4 of Notes to Consolidated Financial Statements for pro forma financial information. Litigation Settlement -- In July 1994, the Company and certain of its former employees were named as defendants in a lawsuit which alleged that one of the Company's founders, who left the Company in March 1995, misappropriated confidential information prior to the Company's founding in April 1992. In August 1996, the Company entered into a settlement with the plaintiff which resulted in a charge to earnings of $4.3 million in the first quarter of fiscal 1997, which included a $3.5 million payment to the plaintiffs and $0.8 million of legal fees. As the payment released the Company from all liabilities associated with the case, the Company has no future obligations to the plaintiffs. The Company denies any wrongdoing on its part or on the part of the founder. Other Income, Net -- Other income, net, was $1.0 million and $0.6 million in fiscal 1997 and 1996, respectively. In both of these periods, other income, net, represented less than 2% of net sales. Other income, net, increased in fiscal 1997 due primarily to interest income earned over four quarters of fiscal 1997 on the net proceeds of $25.7 million from the Company's November 1995 initial public offering ("IPO") compared to interest earnings on IPO proceeds over two quarters for fiscal 1996. Provision for Income Taxes -- The fiscal 1997 income tax provision was $3.8 million (effective rate of 93.8%). The fiscal 1997 tax rate was primarily affected by the one-time charge to operations of $7.4 million for the write-off of purchased in-process research and development related to the IMC acquisition which was not deductible for income tax purposes. Excluding the net effect of the IMC acquisition, the effective tax rate would have been 35%. As of April 30, 1997, a valuation allowance was deemed unnecessary as Company management determined that it is more likely than not that the net deferred tax asset is realizable. In fiscal 1996, the Company's federal and state income tax liabilities were offset by the realization of a portion of its net deferred tax assets. The Company recognized a benefit for its net deferred tax assets to the extent that they were recoverable through tax refunds in the event of future net operating losses. The Company recorded a valuation allowance for the balance of its net deferred tax assets as a result of uncertainty regarding realization of the assets, including the limited operating history of the Company. LIQUIDITY AND CAPITAL RESOURCES As of April 30, 1998, compared to the April 30, 1997 balances, the Company's cash, cash equivalents and short-term investments increased by $19.7 million to $48.1 million. Working capital increased by $27.7 million to $69.6 million, impacted primarily by increases in accounts receivable, cash and cash equivalents and short-term investments, partially offset by increases in accounts payable, deferred revenue, accrued compensation and benefits and other accrued liabilities. The Company generated cash from operating activities totaling $22.7 million and $6.3 million in fiscal 1998 and fiscal 1997, respectively. Net cash provided by operating activities in fiscal 1998 principally related to net income of $21.0 million, depreciation and amortization which are non-cash expenses and increases in current liabilities, partially offset by increases in accounts receivable, prepaid expenses and other and deferred income taxes. 15 16 The Company used $8.0 million and $7.1 million of cash during fiscal 1998 and 1997, respectively, to purchase property and equipment. In addition, the Company used $3.9 million in both fiscal 1998 and fiscal 1997 for net short-term investment purchases. Financing activities provided $6.9 million and $1.7 million during fiscal 1998 and 1997, respectively. The increase in cash provided by financing activities in fiscal 1998 compared to the prior fiscal year was due to an increased quantity of stock options exercised at a higher average exercise price. In June 1998, the Company executed an agreement to acquire 5.9 acres of land in Sunnyvale, California and the accompanying 127,000 square foot building. Under terms of the agreement, the Company paid $5.0 million of the $33.8 million purchase price as a nonrefundable deposit. The agreement allows the Company to assign its rights and obligations to a third-party entity should the Company decide to enter into an operating lease. It is the Company's intent to assign its rights and obligations to a third-party entity and enter into an operating lease, provided the Company can obtain satisfactory leasing terms. In June 1998, the Company signed a 25-year operating lease requiring annual lease payments of $3,084, commencing in October 1999, for a 6.2 acre plot in Sunnyvale, California. In connection with executing the operating lease agreement, the Company also signed an option agreement to purchase the 6.2 acres of land. Under terms of the option agreement, the Company paid a $4.5 million refundable deposit. The option allows the Company to purchase the land, within a 90-day period, commencing in December 1999 at a purchase price of $23.7 million and its rights and obligations under this agreement may be assigned to third parties. It is the Company's intent to assign its purchase option to a third-party entity and to enter into an operating lease with the third-party entity, provided the Company can obtain satisfactory leasing terms. In July 1998, the Company negotiated a $5.0 million unsecured revolving credit facility with a domestic commercial bank. Under terms of the credit facility which expires in July 1999, the Company must maintain various financial covenants. Any borrowings under this agreement bear interest at either LIBOR plus 1% or at the Lender's "prime" lending rate, such rate determined at the discretion of the Company. As of July 17, 1998, there were no borrowings under the credit facility. Excluding the commitments related to the aforementioned properties which the Company intends to assign to a third party and then establish operating leases, the Company currently has no significant commitments other than commitments under operating leases. The Company believes that its existing liquidity and capital resources, including the $5.0 million line of credit, are sufficient to fund its operations for at least the next twelve months. YEAR 2000 ISSUE The "Year 2000 Issue" refers to computer programs which use two digits rather than four to define a given year and which therefore might read a date using "00" as the year 1900 rather than the year 2000. The Company is currently assessing the impact the Year 2000 Issue will have on its internal information systems. The Company believes that the majority of its current products are Year 2000 compliant and that new products are being designed to the Year 2000 compliant. The Company is currently performing extended testing. The Company does not anticipate that addressing the Year 2000 Issue for its internal information systems and current and future products will have a material adverse impact on its operations, financial results or cash flows. However, there can be no assurance that these costs will not be greater than anticipated, or that corrective actions undertaken will be completed before any Year 2000 problems could occur. The Year 2000 Issue could lower demand for the Company's products while increasing the Company's costs. These combining factors, while not quantified, could have a material adverse impact on the Company's business, operating results, financial condition and cash flows. The Company has key relationships with certain suppliers. If these suppliers fail to adequately address the Year 2000 Issue for the products they provide the Company, this could have a material adverse impact on the Company's business, operating results, financial condition or cash flows. The Company is still assessing the effect the Year 2000 Issue will have on its suppliers and, at this time, cannot determine the impact it will have. 16 17 RECENTLY ISSUED ACCOUNTING STANDARDS In June 1997, the Financial Accounting Standards Board issued two new statements of financial accounting standards ("SFAS"). SFAS No. 130, "Reporting Comprehensive Income", requires that an enterprise report, by major components and as a single total, the change in its net assets from nonowner sources during the period. SFAS No. 131, "Disclosures About Segments of an Enterprise and Related Information", establishes annual and interim reporting standards for an enterprise's business segments and related disclosures about its products, services, geographic areas and major customers. The Company has not yet identified its SFAS No. 131 reporting segments. Adoption of these statements will not impact the Company's consolidated financial position, results of operations or cash flows. Both statements are effective for the Company's fiscal year 1999. In October 1997, the American Institute of Certified Public Accountants issued Statement of Position ("SOP") No. 97-2, "Software Revenue Recognition." This statement provides guidance on applying generally accepted accounting principles in recognizing revenue on software transactions. SOP No. 97-2 is effective for transactions entered into during the Company's fiscal year 1999 and thereafter. The Company does not expect that the adoption of this statement will materially impact the Company's financial position, results of operations or cash flows. ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK Not applicable. ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA INDEPENDENT AUDITORS' REPORT To the Shareholders of Network Appliance, Inc.: We have audited the accompanying consolidated balance sheets of Network Appliance, Inc. and its subsidiaries as of April 30, 1998 and 1997, and the related consolidated statements of income, shareholders' equity (deficit) and cash flows for each of the three years in the period ended April 30, 1998. Our audits also included the financial statement schedule listed in Item 14(a)(2). 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 based on our audits. We conducted our audits in accordance with generally accepted auditing standards. 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 includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation.

See notes to consolidated financial statements. 21 22 NETWORK APPLIANCE, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (DOLLAR AND SHARE AMOUNTS IN THOUSANDS, EXCEPT PER-SHARE DATA) 1. THE COMPANY Network Appliance, Inc., incorporated in the state of California in April 1992, and its subsidiaries (the "Company") operate in a single industry segment and are involved in the design, manufacturing, marketing and support of high performance network data storage devices which provide fast, simple, reliable and cost-effective file service for data-intensive network environments. 2. SIGNIFICANT ACCOUNTING POLICIES Fiscal Year -- Although the Company operates on a 52-week or 53-week year ending on the last Friday in April, for presentation purposes the Company has indicated in the accompanying consolidated financial statements that its fiscal year end is April 30. Fiscal 1998, 1997 and 1996 were 52-week years. Fiscal 1999 will be a 53-week fiscal year. Basis of Presentation -- The consolidated financial statements include the Company and its wholly-owned subsidiaries. Intercompany accounts and transactions are eliminated in consolidation. Certain amounts from prior years have been reclassified to conform to current-year presentation. These reclassifications did not change previously reported total assets, liabilities, shareholders' equity or net income. Cash and Cash Equivalents -- The Company considers all highly liquid debt investments with original maturities of three months or less to be cash equivalents. Short-term Investments -- The Company's short-term investments consist of securities with original maturities ranging between three and six months. All of the Company's investments are classified as available-for-sale, and are stated at amortized cost, which approximates fair market value. Short-term investments consist of $10,800 and $6,916 of municipal securities as of April 30, 1998, and April 30, 1997, respectively. No short-term investments were sold during any of the periods presented. Inventories -- Inventories are stated at the lower of cost (first-in, first-out basis) or market. Inventories consist of the following:
APRIL 30, ---------------- 1998 1997 ------ ------ Purchased components....................................... $4,494 $6,775 Work in process............................................ 1,889 1,524 Finished goods............................................. 2,324 1,621 ------ ------ $8,707 $9,920 ====== ======
Property and Equipment -- Property and equipment is stated at cost and is depreciated on a straight-line basis over estimated useful lives which range from two to five years. Leasehold improvements are amortized over their estimated useful lives or the life of the lease, whichever is shorter. Property and equipment consists of the following:
APRIL 30, ------------------ 1998 1997 ------- ------- Computers, related equipment and purchased software...... $16,979 $11,011 Furniture and fixtures................................... 1,962 1,221 Leasehold improvements................................... 2,782 1,520 ------- ------- 21,723 13,752 Accumulated depreciation and amortization................ (9,506) (4,514) ------- ------- $12,217 $ 9,238 ======= =======
22 23 Revenue Recognition -- The Company recognizes revenue and records estimated product return and warranty reserves upon shipment if no material obligations remain outstanding and the collectibility of receivables is deemed to be probable. Service and software subscription revenues are recognized over the terms of the related contractual periods. Combined service and software subscription revenues were less than 10% of net sales for all of the periods presented. Advertising Costs -- Advertising costs are charged to operations when incurred. Advertising expenses for fiscal 1998, 1997 and 1996 were aproximately $1,000, $100 and $25, respectively. Software Development Costs -- The Company capitalizes eligible computer software development costs, which include software enhancement costs, upon the establishment of technological feasibility, which occurs upon the completion of a working model. Software development costs capitalized have not been significant. Foreign Currency Translation -- The functional currency of the Company's foreign subsidiaries is the U.S. dollar. Accordingly, all monetary assets and liabilities are translated at the current exchange rate at the end of the year, nonmonetary assets and liabilities are translated at historical rates and net sales and expenses are translated at average exchange rates in effect during the period. Transaction gains and losses, which are included in other income (expense) in the accompanying consolidated statements of income, have not been significant. Certain Significant Risks and Uncertainties -- The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Such management estimates include the allowance for doubtful accounts receivable, inventory reserves, various accruals and warranty reserves. Actual results could differ from those estimates. The Company is subject to certain risks, including without limitation risks relating to history of operating losses, fluctuating operating results, customer and market acceptance of new products, dependence on new products, rapid technological change, litigation, dependence on growth in the network file server market, expansion of international operations, product concentration, changing product mix, competition, recent management additions, management of expanding operations, dependence on high-quality components, dependence on proprietary technology, intellectual property rights, dependence on key personnel, volatility of stock price, shares eligible for future sale, effect of certain anti-takeover provisions and dilution and the Year 2000 Issue. Concentration of Credit Risk -- Financial instruments which potentially subject the Company to concentrations of credit risk consist primarily of cash equivalents, short-term investments and accounts receivable. Cash, cash equivalents and short-term investments consist primarily of municipal securities, cash accounts held at various banks and a money market fund held at a single financial institution. The Company sells its products primarily to large organizations in different industries and geographies. Credit risk is further mitigated by the Company's credit evaluation process and limited payment terms. The Company does not require collateral or other security to support accounts receivable. The Company maintains an allowance for potential credit losses. Net Income Per Share -- The Company has adopted the provisions of Statement of Financial Accounting Standards No. 128, "Earnings Per Share" ("SFAS 128"), effective in the third quarter of fiscal 1998. SFAS 128 requires the presentation of basic and diluted net income per share. Basic net income per share is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for that period. Diluted net income per share is computed giving effect to all dilutive potential shares that were outstanding during the period. Dilutive potential common shares consist of incremental common shares subject to repurchase, common shares issuable upon exercise of stock options and warrants and convertible preferred stock. All prior-period net income (loss) per-share amounts have been restated to comply with SFAS 128 as well as the two-for-one stock split (See Note 5). 23 24 The following is a reconciliation of the numerators and denominators of the basic and diluted net income per share computations for the periods presented:
YEARS ENDED APRIL 30, ----------------------------- 1998 1997 1996 ------- ------- ------- NET INCOME (NUMERATOR): Net Income, basic and diluted....................... $20,965 $ 250 $ 6,600 ======= ======= ======= SHARES (DENOMINATOR): Weighted average common shares outstanding.......... 33,200 32,329 20,948 Weighted average common shares outstanding subject to repurchase....................................

Statements of Cash Flows -- Supplemental cash flow and noncash investing and financing activities are as follows:
YEARS ENDED APRIL 30, --------------------------- 1998 1997 1996 ------ ------ ------- SUPPLEMENTAL CASH FLOW INFORMATION: Interest paid......................................... $ -- $ -- $ 60 Income taxes paid..................................... 9,402 3,809 1,362 NONCASH INVESTING AND FINANCING ACTIVITIES: Deferred stock compensation........................... 714 (244) 515 Conversion of preferred stock into common stock....... -- -- 12,694 Income tax benefit from employee stock transactions... 4,065 2,487 238 Common stock issued for IMC acquisition............... -- 7,350 -- Deferred stock compensation charge for IMC acquisition........................................ -- 3,150 --
Stock-Based Compensation -- The Company accounts for stock-based awards to employees using the intrinsic value method in accordance with APB No. 25, "Accounting for Stock Issued to Employees." Accounting for Long-Lived Assets -- Effective May 1, 1996, the Company adopted Financial Accounting Standards Board Statement No. 121 ("SFAS 121") "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of," which requires the Company to review the impairment of long- lived assets, certain identifiable intangibles and goodwill related to those assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The adoption of SFAS 121 had no impact on the Company's financial condition or results of operations. Recently Issued Accounting Standards -- In June 1997, the Financial Accounting Standards Board issued two new statements of financial accounting standards ("SFAS"). SFAS No. 130, "Reporting Comprehensive Income", requires that an enterprise report, by major components and as a single total, the change in its net assets from nonowner sources during the period. SFAS No. 131, "Disclosures About Segments of an Enterprise and Related Information", establishes annual and interim reporting standards for an enterprise's business segments and related disclosures about its products, services, geographic areas and change in its net assets from nonowner sources during the period. SFAS No. 131, "Disclosures About Segments of an Enterprise and Related Information", establishes annual and interim reporting standards for 24 25 major customers. The Company has not yet identified its SFAS No. 131 reporting segments. Adoption of these statements will not impact the Company's consolidated financial position, results of operations or cash flows. Both statements are effective for the Company's fiscal year 1999. In October 1997, the American Institute of Certified Public Accountants issued Statement of Position ("SOP") No. 97-2, "Software Revenue Recognition". This statement provides guidance on applying generally accepted accounting principles in recognizing revenue on software transactions. SOP No. 97-2 is effective for transactions entered into during the Company's fiscal year 1999 and thereafter. The Company does not expect that the adoption of this statement will materially impact the Company's financial position, results of operations or cash flows. 3. COMMITMENTS The Company leases its main facility under operating leases that expire through fiscal 2003. Sales offices of the Company are also leased under operating leases which expire through fiscal 2013. The Company is responsible for certain maintenance costs, taxes and insurance under the leases. Future minimum annual lease payments as of April 30, 1998, are as follows:
YEARS ENDING APRIL 30, ---------------------- 1999............................................. $ 4,249 2000............................................. 3,323 2001............................................. 1,049 2002............................................. 886 2003............................................. 707 Thereafter....................................... 2,185 ------- Total lease payments............................... $12,399 =======
Rent expense was $4,278, $1,195 and $755 for the years ended April 30, 1998, 1997 and 1996, respectively. Rent expense under certain Company facility leases is recognized on a straight-line basis over the term of the lease. The difference between the amounts paid and the amounts expensed is classified as long-term obligations in the accompanying consolidated balance sheets. The total of minimum rental payments to be received through 1999 under non-cancelable subleases is $1,268 as of April 30, 1998. 4. ACQUISITION On March 17, 1997, the Company acquired all outstanding shares and options to purchase shares of IMC common stock by issuing 374 shares of the Company's common stock and options to purchase shares of the Company's common stock. The purchase price related to the common stock and options to purchase shares of the Company's common stock was $7,350. IMC was founded in 1996 to develop and commercialize Internet/intranet proxy caching software. Certain key employees of IMC who continued as employees of the Company were also granted vested options to purchase shares of the Company's common stock at a discount to the market price of the Company's common stock immediately preceding the acquisition. In connection with the granting of discounted options to purchase shares of the Company's common stock, the Company recorded a compensation expense of $3,150 in the fourth quarter of fiscal 1997. The Company also recorded a deferred income tax benefit of $1,304, primarily related to the compensation charge. The acquisition was accounted for as a purchase and, accordingly, the results of operations of IMC from the date of acquisition forward have been included in the Company's consolidated financial statements. In connection with the acquisition, intangible assets of $8,362 were acquired, of which $7,369 was reflected as a one-time charge to operations for the write-off of purchased in-process research and development that had not reached technological feasibility and, in management's opinion, had no probable alternative future use. The 25 26 $10,519 combined one-time charge for purchased in-process technology and compensation expense has been reflected in the Company's fiscal 1997 consolidated statement of income within operating expenses. The remaining intangible assets of $993, consisting of existing technology and goodwill, are included in other assets in the accompanying consolidated balance sheets and are being amortized over their estimated useful lives of five years. In connection with the acquisition, net assets acquired were as follows: Current assets.............................................. $ 21 Property and equipment, net................................. 46 Intangible assets, including purchased in-process technology................................................ 8,362 Current liabilities assumed................................. (1,079) ------- Net assets acquired......................................... $ 7,350 =======
The following unaudited pro forma information shows the results of operations for the two fiscal years ended April 30, 1997 as if the IMC acquisition had occurred at the beginning of each period presented and at the purchase price established in March 1997. The results are not necessarily indicative of what would have occurred had the acquisition actually been made at the beginning of each of the respective periods presented or of future operations of the combined companies. The pro forma results for fiscal 1997 combine the Company's results of operations for the fiscal year ended April 30, 1997 with the results of IMC for the period from inception (May 6, 1996) through the date of acquisition and include the $10,519 charge for purchased in-process technology and the related compensation charge, as well as the related tax benefits, and the straight-line amortization of intangible assets over a period of five years. The pro forma results for fiscal 1996 reflect the Company's actual results of operations for that year less the amortization of intangible assets related to the acquisition:

5. SHAREHOLDERS' EQUITY Initial Public Offering -- In November 1995, the Company completed its initial public offering of 4,310 shares of its common stock. Net proceeds from the offering were $25,714. In conjunction with the offering, all outstanding shares of preferred stock automatically converted into common stock. In addition, the Company issued 362 shares of common stock upon the exercise of Series A preferred warrants, and 357 shares of common stock upon the exercise of Series C preferred warrants. The Company received total proceeds of $708 from the exercise of these warrants. Preferred Stock -- The Company's Board of Directors has the authority to issue up to 5,000 shares of preferred stock and to determine the price, rights, preferences, privileges and restrictions, including voting rights, of those shares without any further vote or action by the shareholders. Stock Split -- On November 11, 1997, the Board of Directors approved a two-for-one stock split of the Company's common stock which was effective December 18, 1997. Share and per share data for all periods presented herein have been adjusted to give effect to the split. Stock Option Plans -- The Company adopted the 1993 Stock Option/Stock Issuance Plan (the "1993 Plan") in April 1993. In September 1995, the Company adopted the 1995 Stock Incentive Plan (the "1995 Plan"). The 1995 Plan replaced the 1993 Plan, and provides for the grant of options and the issuance of common stock under terms substantially the same as those provided under the 1993 Plan, except that the 1995 Plan does not allow for the exercise of options prior to vesting. Accordingly, all options and shares issued 26 27 under the 1993 Plan were incorporated into the 1995 Plan upon the effectiveness of the Company's initial public offering. Under the 1995 Plan, the Board of Directors may grant to employees, directors and consultants options to purchase shares of the Company's common stock. The exercise price for an incentive stock option and a nonqualified stock option cannot be less than 100% and 85%, respectively, of the fair market value of the Company's common stock as determined by the Board of Directors on the date of grant. Options granted under the 1995 Plan generally vest at a rate of 25% on the first anniversary of the vesting commencement date and then ratably over the following 36 months. Options expire as determined by the Board of Directors, but not more than ten years after the date of grant. In April 1997, the Board of Directors adopted the Special Non-Officer Stock Option Plan (the "Non-Officer Plan")which provides for the grant of options and the issuance of common stock under terms substantially the same as those provided under the 1995 Plan, except that the Non-Officer Plan allows only for the issuance of nonqualified options to non-officer employees. A summary of the combined activity under the Company's stock option plans and agreements is as follows:

Employee Stock Purchase Plan -- Under the Employee Stock Purchase Plan, employees are entitled to purchase shares of the Company's common stock at 85% of the fair market value at certain specified dates. Of the 700 shares authorized to be issued under this plan, 335 shares were available for issuance at April 30, 1998 and 201 and 164 shares were issued in fiscal 1998 and 1997, respectively, at a weighted average price of $8.41 and $6.33, respectively. Pro Forma Information -- As discussed in Note 2, the Company continues to account for its stock-based awards using the intrinsic value method in accordance with Accounting Principles Board No. 25, "Accounting for Stock Issued to Employees" and its related interpretations. Accordingly, no compensation expense has been recognized in the financial statements for employee stock arrangements with the exception of $270, $85 and $132 in fiscal 1998, 1997 and 1996, respectively, which consists of the amortization of deferred stock compensation related to the granting of nonqualified stock options at exercise prices below market. Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based Compensation," ("SFAS 123") requires the disclosure of pro forma net income and net income per share had the Company adopted the fair value method as of the beginning of fiscal 1996. Under SFAS 123, the fair value of stock-awards to employees is calculated through the use of option pricing models, even though such models were developed to estimate the fair value of freely tradeable, fully transferable options without vesting restrictions, which significantly differ from the Company's stock option awards. These models also require subjective assumptions, including future stock price volatility and expected time to exercise, which greatly affect the calculated values. The Company's calculations were made using the Black-Scholes option pricing model with the following weighted average assumptions:
YEARS ENDED APRIL 30, ----------------------- 1998 1997 1996 ----- ----- ----- Expected life (in years).................................... 2.94 2.90 3.01 Risk-free interest rate..................................... 6.00% 6.06% 5.89% Volatility.................................................. 50% 50% 50% Expected dividend........................................... -- -- --
28 29 The Company's calculations are based on a multiple option valuation approach and forfeitures are recognized as they occur. If the computed fair values of the fiscal 1998, 1997 and 1996 awards had been amortized to expense over the vesting period of the awards, pro forma net income (loss) and net income (loss) per share would have been as follows:
YEARS ENDED APRIL 30, --------------------------- 1998 1997 1996 ------ ------- ------ Net income (loss)....................................... $8,677 $(4,661) $5,824 Net income (loss) per share, basic...................... 0.27 (0.15) 0.32 Net income (loss) per share, diluted.................... 0.24 (0.15) 0.19
However, the impact of outstanding non-vested stock options granted prior to fiscal 1996 has been excluded from the pro forma calculations; accordingly, the fiscal 1998, 1997 and 1996 pro forma adjustments are not indicative of future period pro forma adjustments, when the calculation will apply to all applicable stock options. Deferred Stock Compensation -- In May 1995, the Company issued stock options for the purchase of 1,063 shares of common stock at $0.14 per share. The Company recognized $515 of deferred compensation in May 1995 equal to the difference between the option price as determined by the Board of Directors and $0.63 (the deemed fair value for financial reporting purposes) for each option. The Company is amortizing the deferred compensation expense ratably over the four-year period in which the options vest. In fiscal 1998, the Company recorded $714 of deferred compensation, primarily related to the grant of stock options to certain highly compensated employees. Under terms of the 1995 Stock Option Plan, highly compensated employees as defined by Company's management are eligible to contribute between $15 to $75 in annual salary for the rights to be granted nonqualified stock options. The discount from fair market value which is equal to the amount of salary contributed has been recorded as deferred compensation expense. The Company is amortizing the deferred compensation expense ratably over a one-year period. 6. EMPLOYEE BENEFIT PLAN The Company has established a 401(k) tax-deferred savings plan ("Savings Plan"). Employees meeting the eligibility requirements, as defined, may contribute specified percentages of their salaries. The Company contributed $202 and $119 for fiscal 1998 and 1997, respectively. The Company did not make any contributions to the Savings Plan in fiscal 1996. 7. INCOME TAXES The provision for income taxes consists of the following:
YEARS ENDED APRIL 30, ----------------------------- 1998 1997 1996 ------- ------- ------- CURRENT: Federal............................................. $12,132 $ 5,062 $ 1,880 State............................................... 2,199 1,525 220 ------- ------- ------- Total current....................................... 14,331 6,587 2,100 ------- ------- ------- DEFERRED: Federal.............................................

(1,749) (2,794) (2,100) ------- ------- ------- Provision for income taxes.................. $12,582 $ 3,793 $ -- ======= ======= =======
Deferred income taxes result from differences in the timing of certain expense items for tax and financial reporting purposes. 29 30 The provision for income taxes differs from the amount computed by applying the statutory federal income tax rate as follows:
YEARS ENDED APRIL 30, ---------------------------- 1998 1997 1996 ------- ------ ------- Tax computed at federal statutory rate................. $11,741 $1,415 $ 2,310 State income taxes, net of federal benefit............. 1,482 764 405 Non-deductible acquisition charges related to the IMC acquisition.......................................... -- 2,904 -- Research and experimentation credit....................

The income tax benefits associated with dispositions from employee stock transactions reduced taxes currently payable by $4,291, $2,487 and $238, respectively, for fiscal 1998, 1997 and 1996. Income before income taxes is as follows:
YEARS ENDED APRIL 30, --------------------------- 1998 1997 1996 ------- ------ ------ Domestic................................................ $33,175 $3,983 $6,580 Foreign................................................. 372 60 20 ------- ------ ------ Total......................................... $33,547 $4,043 $6,600 ======= ====== ======
Current net deferred tax assets are $5,280 and $3,100, as of April 30, 1998 and April 30, 1997, respectively. Non-current net deferred tax assets at April 30, 1998 and 1997 of $1,363 and $1,794, respectively, are included in other assets within the accompanying consolidated balance sheets. The components of the Company's net deferred tax assets are as follows:
APRIL 30, ---------------- 1998 1997 ------ ------ Reserves and accruals not currently deductible for tax purposes............................................... $4,599 $2,662 Tax benefit of options issued in IMC acquisition.......... 1,074 1,304 Net operating loss carryforwards.......................... 236 116 Depreciation.............................................. 197 369 Deferred rent............................................. 66 80 Capitalized research and development costs................ -- 142 Other..................................................... 471 221 ------ ------ Deferred tax assets............................... $6,643 $4,894 ====== ======
As of April 30, 1998, the Company had federal net operating loss carryforwards of approximately $674 available to offset future taxable income. These carryforwards expire in fiscal 2010. 8. OPERATIONS BY GEOGRAPHIC AREA AND SIGNIFICANT CUSTOMERS The Company operates primarily in one industry segment: the design, manufacturing and marketing of high-performance network data storage devices. 30 31 The Company's European operations primarily consist of sales by its subsidiaries in the United Kingdom, France, Germany and Italy to either unaffiliated European customers or to independent distributors.
YEARS ENDED APRIL 30, --------------------- 1998 1997 --------- -------- NET SALES: North America............................................... $138,379 $83,342 Europe...................................................... 27,784 9,991 -------- ------- Total net sales................................... $166,163 $93,333 ======== ======= OPERATING INCOME: North America............................................... $ 32,285 $ 3,023 Europe...................................................... 373 60 -------- ------- Total operating income............................ $ 32,658 $ 3,083 ======== ======= IDENTIFIABLE ASSETS: North America............................................... $105,601 $66,019 Europe...................................................... 10,135 2,922 -------- ------- Total assets...................................... $115,736 $68,941 ======== =======
North America revenues include export sales to Asia which amounted to less than 10% of total net sales for all periods presented. Sales, operating income and identifiable assets of the Company's foreign operations were less than 10% of the comparable amounts on a consolidated basis in fiscal 1996. No customer accounted for 10% or more of net sales in fiscal 1998, 1997 or in fiscal 1996. 9. LITIGATION The computer industry is characterized by frequent litigation regarding intellectual property rights. During fiscal 1995 a lawsuit of this nature was filed against the Company and two of its shareholders (the "Whipsaw Litigation"). During the first quarter of fiscal 1997, the Company settled the Whipsaw litigation and recorded a pre-tax expense of $4,300 ($3,500 in payments to the plaintiffs and $800 in legal fees). In connection with the settlement, the Whipsaw group released the Company from all liabilities. 10. SELECTED QUARTERLY FINANCIAL DATA (UNAUDITED)

SUBSEQUENT EVENTS In June 1998, the Company executed an agreement to acquire 5.9 acres of land in Sunnyvale, California and the accompanying 127,000 square foot building. Under terms of the agreement, the Company paid $5,000 of the $33,750 purchase price as a nonrefundable deposit. The agreement allows the Company to assign its rights and obligations to a third-party entity should the Company decide to enter into an operating lease. It is the Company's intent to assign its rights and obligations to a third-party entity and enter into an operating lease, provided the Company can obtain satisfactory leasing terms. In June 1998, the Company signed a 25-year operating lease requiring annual lease payments of $3,084, commencing in October 1999, for a 6.2 acre plot in Sunnyvale, California. In connection with executing the operating lease agreement, the Company also signed an option agreement to purchase the 6.2 acres of land. Under terms of the option agreement, the Company paid a $4,500 refundable deposit. The option allows the Company to purchase the land, within a 90-day period, commencing in December 1999 at a purchase price of $23,745 and its rights and obligations under this agreement may be assigned to third parties. It is the Company's intent to assign its purchase option to a third-party entity and to enter into an operating lease with the third-party entity, provided the Company can obtain satisfactory leasing terms. In July 1998, the Company negotiated a $5,000 unsecured revolving credit facility with a domestic commercial bank. Under terms of the credit facility which expires in July 1999, the Company must maintain various financial covenants. Any borrowings under this agreement bear interest at either LIBOR plus 1% or at the Lender's "prime" lending rate, such rate determined at the discretion of the Company. As of July 17, 1998, there were no borrowings under the credit facility. ITEM 9.CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE Not applicable. PART III ITEM 10.

                         AGREEMENT OF PURCHASE AND SALE



              THIS AGREEMENT OF PURCHASE AND SALE ("Agreement") is entered into

         A. Seller owns and desires to sell to Buyer real property comprised of
approximately 5.86 acres, located at 495 Java Drive, Sunnyvale, California, as

THE CONDITION OF THE PROPERTY OR RESTORE THE SAME AFTER ANY CASUALTY (EXCEPT AS
EXPRESSLY PROVIDED IN SECTION 12), OR (B) EXPEND MONEY OR POST A BOND TO REMOVE
A TITLE ENCUMBRANCE OR DEFECT (EXCEPT LINES OR ENCUMBRANCES CREATED BY SELLER)
OR CORRECT ANY MATTER SHOWN ON A SURVEY OF THE PROPERTY. IN THE EVENT BUYER
SEEKS SPECIFIC PERFORMANCE AND IS UNSUCCESSFUL IN OBTAINING SPECIFIC
PERFORMANCE, BUYER SHALL BE ENTITLED TO TERMINATE THIS AGREEMENT AND RECOVER THE
DEPOSIT. BUYER SHALL BE DEEMED TO HAVE ELECTED TO TERMINATE THIS AGREEMENT IF

("Purchase Price") for the Property of Thirty-Three Million Seven Hundred Fifty

The Purchase Price shall be subject to adjustment pursuant to Section 6 below.

                  5. Conditions Precedent. At or before Close of Escrow the
following conditions precedent ("Conditions Precedent") shall be either
satisfied or waived by Buyer as a condition to Buyer's obligation to proceed
with the purchase of the Property:

                      (a) Title. The term "Conditions of Title" shall refer to
those exceptions to title (including, without limitation, Title Company's
standard printed exceptions to title with respect to an ALTA Owner's Extended
Form policy of title insurance (an "ALTA Policy") listed on EXHIBIT C
incorporated herein by reference, the lien for real property taxes not
delinquent, any current assessments (subject to Seller's obligation to pay
delinquent assessments or credit same to the Purchase Price at closing), the
effect of the Lot Line Adjustment and the CC&R's and any other encumbrances or
matters of title caused or approved in writing by Buyer. On the Closing Date,
Title Company shall be unconditionally committed to issue (a) an American Land
Title Association ("ALTA") Extended Title Policy Form B (1970) for the Property
("ALTA Title Policy"), with a liability limit in the amount of the Purchase
Price and insuring fee title vested in Buyer, and (b) endorsements to the ALTA
Title Policy (i) to provide Buyer with assurance that the Property is the same
as shown on the Survey, (ii) to 


   5

provide Buyer with assurance that the Property is contiguous with the property
known as 475 Java Drive, and (iii) such other endorsements as Buyer may
reasonably request, including without limitation zoning, tax parcel, access, and
owner's comprehensive (ALTA 100, modified for owner, or equivalent) endorsements
(collectively, the "Endorsements"); provided, however, the availability of such
Endorsements shall not be a Condition Precedent to Buyer's obligation hereunder.
Buyer shall take title to the Property subject to the Conditions of Title.

                      (b) Survey. Buyer has approved a certified ALTA survey of
the Property prepared by Kier & Wright dated April 15, 1998 ("Survey"). Any
revisions (including certification to Buyer) to the ALTA survey previously
provided to Buyer by Seller which are requested by Buyer shall be at Buyer's
sole cost and expense. At Close of Escrow Seller shall deliver to Buyer the
Survey.

                      (c) Property Documents. Buyer has reviewed and approved
all of the reports listed on EXHIBIT D attached hereto and incorporation herein
("Property Documents"). As of the Close of Escrow there shall have been no
material adverse change in the physical condition of the Property as described
in the Property Documents which would materially, adversely affect Buyer's use
and occupancy of the Property and Seller shall deliver to Buyer its certificate
representing and warranting that (except as described in such certificate) (i)
there has been no such material adverse change in such physical condition
between the Execution Date and the Close of Escrow, (ii) all Improvements
completed by Seller prior to the Closing Date have been built in accordance with
the Seller Plans and in compliance with all applicable laws and the CC&Rs, (iii)
all asbestos containing building materials contained in the improvements located
on the Land as of the date the Land was acquired by the Seller have been removed
and transported to a suitable disposal site, in compliance with law and any
contracts concerning the removal, transportation, or disposal of asbestos
located at or on the Land had been fully performed as of the Closing Date and
(iv) there are no agreements which would be binding upon the Property or the
Buyer following Close of Escrow except as expressly contemplated by this
Agreement. ("Seller's Closing Certificate").

                      (d) Completion of Improvements. Seller shall have
substantially completed the Improvements in accordance with the Work Letter.

                      (e) Seller's Performance. Seller shall have performed all
of its obligations under this Agreement.

                  6. Completion of Improvements.

                      (a) Completion of Improvements. Seller shall be obligated
to complete the Improvements in accordance with the Work Letter.

                      (b) Milestones. The parties have set forth certain events
which must occur prior to or during construction of the Improvements (each, a
"Milestone"), which must be accomplished by Seller on or before certain
prescribed dates or Buyer shall have the right to terminate this Agreement and
pursue certain remedies described in Section 6(e) below. The Milestones to which
Buyer and Seller have agreed are as follows:


   6

                  (1) Construction of the foundation for the building (included
                  within the Improvements) shall have commenced no later than
                  June 10, 1998; and

                  (2) The Improvements shall have been substantially completed
                  (as defined in the Work Letter) in accordance with Seller's
                  Plans, except for landscaping, on or before June 17, 1999.

The Milestone dates set forth above shall be extended as follows: (A) One day
for each day of delay caused by Buyer Delays (as defined in the Work Letter),
(B) One day for each day of Force Majeure Events (as defined in the Work
Letter), however, the maximum number of days that any such Milestone can be
extended for such Force Majeure Delays shall be limited to a total of sixty (60)
days except that no such limit shall apply in the event Seller's Plans are
changed in response to a request by Buyer under circumstances where Seller has
informed Buyer in writing that Seller believes such change is material and would
not be acceptable to Seller if Seller were building the Improvements on a
speculative basis rather than for Buyer, and (C)

         By the amount of time required to complete any arbitration process
resulting from disputes between Seller and Buyer arising prior to the Milestone,
to the extent the arbitration process (and the issue being arbitrated) actually
causes a delay in achieving such Milestones. The aggregate extension of the
Milestone dates provided for herein shall be referred to as the "Milestone
Extension Period". The parties acknowledge that Seller has satisfied the
Milestone set forth in clause (i) above.

                      (c) Changes requested by Buyer. Buyer has reviewed and
approved the Seller Plans (as defined in the Work Letter) for construction of
the Improvements. Buyer shall have the right to submit written requests for
changes to the existing plans for the Improvements which changes shall be
subject to Seller's written consent. Seller shall not unreasonably withhold it's
consent to such changes so long as (i) such changes do not extend the time
period for substantial completion of the Improvements by more than ninety (90)
days as reasonably determined by Seller (Buyer acknowledges that the date
contemplated for substantial completion of the Improvements as of the date
hereof without giving effect to any Milestone Extension Period or any requests
by Buyer hereunder is March 17, 1999), and (ii) Buyer approves in writing
Seller's estimated adjustment to the Purchase Price caused by such changes.

                      (d) Adjustment to Purchase Price.

                           (1) If any changes requested by Buyer and approved by
Seller pursuant to this Section 6 increase or decrease the cost of constructing
the Improvements the Purchase Price shall be adjusted accordingly. Such costs
shall include but not be limited to Seller's carrying costs (including real
property taxes, cost of financing on all costs associated with the Property at a
rate of Comerica Bank's Prime Rate plus 1%, etc.) and hard and soft costs;
provided, however, such costs shall not include any mark-up charged by Seller.

                           (2) In the event that the Close of Escrow occurs
prior to completion of the Improvements, Seller shall be obligated to complete
the Improvements following Close of Escrow. In such event the Purchase Price
shall be reduced by the Interest Savings. The "Interest Savings" shall mean the
amount of interest that Seller would have paid to Comerica Bank between the
Closing Date and the date estimated (as of the closing date) for 


   7

substantial completion of the Improvements based upon the loan balance as of the
Closing Date and Seller's best available interest rate pursuant to its loan from
Comerica Bank. Buyer and Seller shall execute such additional documents and
instruments as may be necessary to accomplish the purposes of this
sub-paragraph, including but limited to, an agreement allowing Seller access to
the Property for the purposes of completion of the Improvements, appropriate
requirements for insurance to be carried by Buyer as owner of the Property, etc.

                      (e) Right to Terminate. If any Milestone set forth in
Section 6(b) is not achieved by Seller, Buyer shall have the right to terminate
this Agreement by written notice to Seller at any time within ten (10) business
days after Seller's failure to achieve the particular Milestone; provided,
however, if the conditions described in Section 6(f) are met Buyer shall have
the right to elect the remedies described in Section 6(f). If Buyer exercises
its termination right, Buyer shall be entitled to the remedies provided in this
Section 6(e), which shall be Buyer's sole and exclusive remedies with respect to
Seller's failure to achieve any Milestone. If Buyer exercises a termination
right pursuant to this Section 6(e) and Seller believes that the Milestone was
achieved by the appropriate date (as extended by the Milestone Extension
Period), the parties agree to submit the dispute concerning Seller's failure to
achieve that particular Milestone, and Buyer's resulting right to terminate the
Lease, to binding arbitration pursuant to the provisions of Section 16.
Notwithstanding any other provision of this Agreement or the Work Letter, if
Seller fails to achieve any Milestone Buyer's sole and exclusive remedies shall
be to either (i) elect to proceed under Section 6(f) if the conditions set forth
therein have occurred, or (ii) terminate this Agreement and receive the Deposit
and damages from Seller (which shall be paid within thirty (30) days of the date
of Buyer's notice of termination, or, if the parties resort to arbitration
pursuant to the provision set forth above, then within thirty (30) days of
Buyer's prevailing on said termination in arbitration) in the following amounts
(all clauses referenced are in Paragraph 6(b)): $250,000, as liquidated damages
for failure of Seller to achieve the Milestone described in clause (1); and
$500,000, as liquidated damages for failure of Seller to achieve the Milestone
described in clause (2). Seller and Buyer acknowledge and agree that if Seller
fails to achieve the Milestone described in clause (1) or (2) and Buyer elects
to terminate this Agreement pursuant to this paragraph as a result thereof, the
damages which Buyer will suffer are difficult, if not impossible to calculate,
and that the above-described liquidated damages are a fair and reasonable
estimate of the damages that Buyer would suffer with respect to a failure to
achieve the Milestone described in clause (1) or (2).

                      (f) Buyer's Self Help Remedy. Notwithstanding the above,
in the event that all of the following are true: (i) Seller has failed to
achieve a Milestone set forth in Section 6(b), and (ii) Buyer is not in a
continuing default under this Agreement, then Buyer shall have the right to
substantially complete the Improvements and offset its actual out of pocket
costs and expenses incurred in connection therewith against the Purchase Price.

         7. No Incumbrance or Transfer. Except as provided herein, Seller shall
not incumber, lease, transfer, assign or sell all or any portion, or interest
in, the Property, or enter into any agreement or contract effecting or relating
to the Property without Buyer's prior written consent, which consent may be
withheld in Buyer's sole discretion. Seller shall be entitled to encumber the
Property for the purpose of securing one or more construction loans. Seller may
also implement the Lot Line Adjustment, record the CC&R's and execute such other
contracts (but not contracts or encumbrances that will be binding upon Buyer or
the Property after the 


   8

Close of Escrow) as may be necessary or advisable in connection with performing
its obligations hereunder including completion of the Improvements.

                  8. Escrow.

         (a) Escrow. Within two (2) Business Days of the Execution Date, Seller
shall establish an escrow ("Escrow") with the Escrow Agent for the close of this
transaction. An executed copy of this Agreement shall be deposited with the
Escrow Agent by Buyer and this Agreement, together with Seller's Additional
Escrow Instructions (as hereinafter defined), if any, and Buyer's Additional
Escrow Instructions (as hereinafter defined), if any, shall constitute Escrow
Agent's escrow instructions for closing Escrow. Escrow shall close ("Close of
Escrow") on or before the Closing Date.

         (b) Seller. On or prior to the Closing Date Seller shall deposit the

Deed in usual form setting forth all exceptions to title created or suffered by
Seller which are not to be removed at or prior to Closing;

                      (ii) Non-Foreign Person Certificates. Duly executed
non-foreign person certificates ("Non-Foreign Person Certificates") in usual
form sufficient to relieve Buyer of any withholding requirements pursuant to the
provisions of Section 1445 of the Internal Revenue Code of 1986 as amended (the
"Code") and Section 18805 of the California Revenue and Taxation Code and a
California Form 590-RE certifying that Seller has a permanent place of business
or is qualified to do business in the State of California;

                      (iii) Assignment of Intangible Property. An assignment, in
a form reasonably approved by Buyer and Seller, of all Seller's rights, title,
and interest to any and all plans, permits, approvals, entitlements and other
intangible property relating to the Property (the "Assignment of Intangibles");

                      (iv) Assignment of Warranties. An assignment by Seller, in

                      (v) Closing Certificate. Seller's Closing Certificate, in
a form reasonably approved by Buyer and Seller; and

                      (vi) Additional Escrow Instructions and Documents. Such
additional escrow instructions ("Seller's Additional Escrow Instructions") and
documents as Escrow Agent may reasonably require of Seller to close the sale of
the Property in accordance with this Agreement, which instructions shall not be
inconsistent with the terms of this Agreement.

         (c) Buyer. On or prior to the Closing Date Buyer shall deposit the
following into Escrow:


   9

                      (i) Cash Payment. The Cash Payment;

                      (ii) Additional Cash. Additional cash in the amount
necessary to pay Buyer's share of closing costs and prorations, as hereinafter
set forth;

                      (iii) Release and Assumption. The Release and Assumption
provided for in Section 11(g); and

                      (iv) Additional Escrow Instructions and Documents. Such
additional escrow instructions ("Buyer's Additional Escrow Instructions") and
documents as Escrow Agent may reasonably require of Buyer to close the sale of
the Property in accordance with this Agreement.

                  9. Close of Escrow.

         (a) Time. When the Escrow Holder has confirmed that Title Company is in
a position to issue an ALTA Extended Policy (Form B-1970) insuring title to the
Property as being vested in Buyer in accordance with Section 5(a) and all
documents and funds required hereby have been deposited with Escrow Agent,
Escrow Agent shall cause Close of Escrow to occur as provided below.

                      (iii) Escrow Cancellation Costs. Notwithstanding the
provisions of subsection (i) above, if Escrow fails to close due to Seller's
default, Seller shall pay all Escrow cancellation charges. If Escrow fails to
close due to Buyer's default, Buyer shall pay all Escrow cancellation charges.
If Escrow fails to close for any reason other than the foregoing, Buyer and
Seller shall each pay one-half (1/2) of any Escrow cancellation charges. "Escrow
cancellation charges" means all fees, charges, and expenses incurred by Escrow

Preliminary Report and other title matters.

         10. Brokers. Each of Buyer and Seller represents to the other party
that, other than Cornish & Carey representing Buyer and CPS, representing Seller

any of the transactions contemplated by this Agreement. Buyer shall indemnify,
defend and hold Seller harmless from and against any loss, cost or expense,

claiming by or through Buyer, other than the Brokers. Seller shall indemnify,

         11. Seller's Representations, Warranties and Covenants.

         (a) Seller's Representations and Warranties. Seller hereby makes the
following representations and warranties to Buyer which representations and
warranties shall survive the Close of Escrow for a period of twelve (12) months
(at which time these representations and warranties shall expire):

                      (i) Litigation; Government Action. Except as disclosed to
Buyer in writing, there is no claim, litigation, notice that the Property is in
violation of law, or governmental investigation presently pending with respect
to which Seller has been served with process or other notice thereof or, to the
best of Seller's knowledge, otherwise pending or threatened, against or relating
to the Property.


   11

                      (ii) Condemnation. There is presently no pending
condemnation of the Property or any part thereof with respect to which Seller
has been served with process or other notice thereof nor, to the best of
Seller's knowledge, is any such condemnation otherwise pending or contemplated.

                      (iii) Leases. There are no leases or other occupancy
agreements relating to the Property.

                      (iv) Hazardous Materials.

                                    (1) For purposes hereof, "Hazardous
Materials" shall mean any and all asbestos, radioactive material, hazardous
waste, toxic substance or related material, including but not limited to those
materials and substances defined as "hazardous substances", "hazardous
materials", "hazardous wastes" or "toxic substances" in any California or
federal law or regulation.

                                    (2) Seller has not released or discharged,
or caused to be released or discharged, upon the Property any Hazardous
Materials, and to the best of Seller's knowledge, except as disclosed in the
Property Documents, there are no Hazardous Materials present on, in, or under
the Property.

                                    (3) To the best of Seller's knowledge, the
Property Documents are all of the documents and reports in Seller's possession
pertaining to Hazardous Materials on or at the Property.

                      (v) Property Documents. There are no other documents or
reports in Seller's possession or under Seller's control other than the Property
Documents, describing the condition of the Property concerning the presence of
Hazardous Materials, the geotechnical condition of the soils or other like
physical condition of the Property as of the Execution Date; provided, however,
the improvements demolished and removed by Seller contained asbestos. Seller
acknowledges and agrees that the demolition and removal of the existing
improvements including the asbestos containing materials therein and all costs
in connection therewith is the sole responsibility of Seller.

         (b) Organization and Authority. Seller is a California limited
partnership validly existing and in good standing under the laws of California.
Seller and has full power to enter into this Agreement and is duly qualified to
transact business in California. The execution, delivery, and performance of
this Agreement have been duly authorized and approved by all requisite action
and the consummation of the transactions contemplated hereby will be duly
authorized and approved by all requisite action of Seller and no other
authorizations or approvals, whether of governmental bodies or otherwise, will
be necessary in order to enable Seller enter into or to comply with the terms of
this Agreement.

         (c) Binding Effect of Documents. This Agreement and the other documents
to be executed by Seller hereunder, upon execution and delivery thereof by
Seller, will have been duly entered into by Seller, and will constitute legal,
valid and binding obligations of Seller. Neither this Agreement nor anything
provided to be done under this Agreement 


   12

violates or shall violate any contract, document, understanding, agreement, or
instrument to which Seller is a party or by which it is bound.

         (d) "Best Knowledge" Definition. For purposes of this Section 11, the
term "to the best of Seller's knowledge" shall mean the current actual knowledge
of John Mozart and Steve Dostart after usual inquiry in connection with the
operation of the Property. Seller represents that John Mozart and Steve Dostart
are the representatives of Seller with supervisory responsibilities concerning
the Property who would, in the ordinary course of their responsibilities,
receive notice from persons or entities of any of the matters described in the
representations and warranties in this Section 11.

         (e) "As-Is" Condition; Release and Assumption. If Seller breaches any
representation, warranty, or covenant hereunder prior to Closing and Buyer
closes escrow with knowledge thereof, Buyer shall be deemed to waive such
breach. Except as expressly provided in this Agreement and in Seller's Closing
Certificate, Seller makes no representations or warranties of any kind, express
or implied, written or oral, as to the physical condition of the Property; the
uses of the Property or any limitations thereon, including, without limitation,
zoning, environmental or other laws, regulations or governmental requirements;
the utilities or other physical equipment and fixtures on the Property, the
costs of operating the Property or any other aspect of the economic operations
on the Property; the possibility of future assessments of charges being levied
against the Property or imposed as a condition to development or construction;
or the condition of the soils or groundwater of the Property. Except as provided
herein, Buyer specifically acknowledges that it is acquiring the Property in an
"as-is" condition (as such term is most broadly construed), in reliance upon its
own inspection and investigation of the Property. Except as expressly provided
herein, Seller makes no representation or warranties with respect to the
condition of title to the Property, and Buyer agrees that it will rely solely on
its policy of title insurance. At closing, and as a condition to Seller's
obligations hereunder, Buyer shall, pursuant to a form of Release and Assumption
("Release and Assumption") prepared by Seller and delivered to Buyer for
approval by Buyer within ten (10) days after the Execution Date, (1) release
Seller from any and all claims, liability or causes of action (except for the
express representations and warranties herein and in Seller's Closing
Certificate to the extent the same survive closing) in connection with the
Property and (2) assume all of Seller's obligations under any and all laws and
regulations pertaining to the Property (except (i) those occurring prior to the
Close of Escrow, or (ii) for Seller's obligations in connection with completion
of the Improvements, if the Improvements are not completed as of the Closing
Date).

         12. Loss by Fire or Other Casualty; Condemnation.

                      (a) Condemnation and General Casualty. Buyer shall be
bound to purchase the Property for the full Purchase Price as required by the
terms hereof, without regard to the occurrence or effect of any damage to or
destruction of any improvements or condemnation of any portion of the Property.
In the event of a casualty Buyer may elect to purchase the Property pursuant to
the terms of this sub-paragraph (a) or to require Seller to repair and complete
the Improvements pursuant to sub-paragraph (c). Such election shall be made by
written notice given within thirty (30) days following the casualty. If Buyer
elects to proceed pursuant to this sub-paragraph (a), the Purchase Price shall
be credited by the amount of any insurance proceeds or condemnation awards
(excluding proceeds or awards payable in respect of


   13

carrying costs or other costs born by Seller and not subject to adjustment of
the Purchase Price as provided herein) collected by Seller as a result of any
such damage or destruction or condemnation less any monies actually expended by
Seller to repair any damage, plus any deductible amounts attributable to such
damage or destruction, or such proceeds shall be assigned to Buyer if not then
collected.

                      (b) Seller Cooperation. If Seller assigns the proceeds of
any insurance policy to Buyer pursuant to Section 12(a), Seller shall cooperate
with Buyer in presenting and prosecuting the claim with Seller's insurance
carriers, shall follow Buyer's instructions with respect thereto (except to the
extent Seller is advised by counsel that following a particular instruction
would expose Seller to liability, or to the extent Seller would incur additional
cost to follow such instruction which is not paid by Buyer), and will not settle
any such claim without Buyer's written approval.

                      (c) Insurance. Seller shall purchase and keep in force a
policy or policies of fire and property damage insurance (including coverage for
flood and earthquake, if available) covering loss or damage to the Property
(including the improvements) in the amount of the full replacement value thereof
including comprehensive builder's risk/course of construction insurance. In the
event of a casualty and election by Buyer (pursuant to sub-paragraph (a) above)
to require Seller to repair and complete the Improvements, Seller shall be
obligated to repair and complete the Improvements pursuant to the terms and
conditions hereof subject to extension of all of the dates for performance and
the closing date for the delay caused by the casualty. In such event there shall
be no adjustment to the Purchase Price for increase costs sustained by Seller
(whether or not such costs are covered by insurance) in connection with or
caused by the casualty. Notwithstanding anything to the contrary herein, in the
event of a casualty under circumstances where the cost of completion of the
Improvements exceeds the Available Funds by an amount in excess of $1,000,000,
Seller may terminate this agreement unless Buyer elects to pay such excess. The
term "Available Funds" shall mean the sum of (i) insurance proceeds, (ii)
deductibles in respect of the casualty loss and (iii) the amount of the cost of
the Improvements which Buyer had not yet disbursed (and for which Buyer had not
incurred liability) as of the date of the casualty.

         13. Successors and Assigns. The terms, covenants, and conditions herein
contained shall be binding upon and inure to the benefit of the successors and
assigns of the parties hereto. Buyer may assign it's rights under this Agreement
to a financing entity in connection with a synthetic lease transaction without
the need for Seller's prior written consent but no such assignment shall relieve
the assignor from primary liability for its obligations hereunder. Prior to the
acquisition of the Property, Buyer intends to assign Buyer's interest under this
Agreement to an entity (the "Lessor"), who will then lease all of the acquired
portions of the property to Buyer, as tenant ("Tenant"), pursuant to a synthetic
lease ("Lease") to be executed by Lessor and Tenant, pursuant to which Tenant
shall have the right to construct certain improvements thereon, pursuant to
plans and specifications approved by Lessor and Tenant. The parties acknowledge
that (a) Tenant is intended to be the ultimate occupant and user of the Real
Property, and (b) the improvements to be constructed thereon are being designed
for Tenant's benefit and to Tenant's specifications. Therefore, the parties
acknowledge that Tenant is an intended third party beneficiary of all of
Seller's covenant, representations, warranties and obligations under this
Agreement.


   14

         14. Entire Agreement. This Agreement contains all of the covenants,
conditions and agreements between the parties and shall supersede all prior
correspondence, agreements, and understandings, both oral and written. No
provisions of this Agreement may be amended or modified in any manner except by
an agreement in writing duly executed by the parties hereto.

         15. Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of California as applied to agreements
among California residents which are entered into and performed entirely within
California.

         16. Attorneys' Fees; Arbitration.

                      (a) Attorneys' Fees. In the event of any litigation or
arbitration regarding the rights and obligations under this Agreement, the
prevailing party shall be entitled to recover, in addition to damages,
injunctive or other relief, reasonable attorneys' fees expert witness fees, and
court costs.

                      (b) Arbitration of Disputes. ANY CONTROVERSY OR CLAIM
ARISING OUT OF THIS AGREEMENT SHALL BE SETTLED BY ARBITRATION IN ACCORDANCE WITH
THE RULES OF THE AMERICAN ARBITRATION ASSOCIATION FOR THE ARBITRATION OF
COMMERCIAL DISPUTES, AND JUDGMENT ON THE AWARD RENDERED BY THE ARBITRATOR(S) MAY

have seven (7) business days to notify Seller in writing of any disapproval. Any
written notice containing Buyer's disapproval, shall also include the specific
reasons for disapproval. If Buyer fails to notify Seller of any disapproval
within the applicable time periods provided above, Buyer shall be deemed to have
approved the submitted revised plans and specifications.

                  5. Change Orders. Any changes requested by Buyer that
necessitate revisions or changes in Seller's Plans or the design or construction
of the Improvements or delay the commencement or completion of Improvements,
shall be subject to the prior written approval of 

   25

Seller subject to the standard for approval and Purchase Price adjustment
provided for in Section 6(c) and 6(d), respectively, in the Purchase Agreement;
any such changes approved by Seller shall be a "Change Order" hereunder. Before
any such design and/or construction changes are made, Buyer shall pay to Seller
the full costs to be incurred by Seller in connection with such Change Order if,
and to the extent, the aggregate cost of all Change Orders exceeds $3,000,000.
Any such Change Order funded by Seller shall be a basis for adjustment of the
Purchase Price pursuant to Section 6(d) of the Agreement to which this Work
Letter is attached as an exhibit. Seller and Buyer shall hold weekly
construction meetings during the development of the Project and shall cooperate
in good faith during the weekly meetings to review and agree upon Change Orders.
In those instances in which proposed revisions to Seller's Plans result from a
Change Order, Seller shall cause the Seller's contractor, if applicable, to
determine the additional cost or savings from such Change Order, and Seller
shall promptly so notify Buyer. The additional costs or savings resulting from
such Change Orders (and the time impact of said Change Order, if any) shall be
supported by detailed trade cost breakdowns prepared by Seller's Contractor.
Buyer shall, within five (5) business days after such notification by Seller,
inform Seller in writing whether or not Buyer desires to proceed with such
Change Order. In the event that Buyer fails to inform Seller within such five
(5) day period that Buyer desires to proceed with such Change Order, Seller
shall not make any changes(s) to the Improvements included in such Change Order.
If Buyer informs Seller within such five (5) day period that Buyer does wish to
proceed with the proposed Change Order, the proposed Change Order shall be
incorporated in the Improvements if applicable thereto and Seller's contractor
shall proceed with the work covered by the Change Order and Buyer shall be
responsible for all costs and expenses incurred in connection therewith as
aforesaid. The Seller shall pass through to Buyer the Seller's contractor's
percentage mark-up (which shall not be greater than the mark-up charged to
Seller) for overhead and profit (which shall include all charges for general
conditions) for Change Orders to the Improvements without additional mark-up
from Seller. All Change Orders shall be in writing and shall be on such AIA form
as required by Seller and/or Seller's contractor. Buyer shall evidence in
writing it's approval of such Change Order prior to Seller's approval of same.

                  6. Substantial Completion. For purposes of this Work Letter
and the Purchase Agreement, the Improvements shall be deemed "substantially
complete" at such time as (i) Seller has completed work in accordance with
Seller's Plans and in compliance with all legal requirements applicable to the
Improvements at the time the permits where obtained for the construction thereof
subject to completion and correction of items on Seller's architect's punch
list, and landscaping, (ii) Seller has assured Buyer access to the Building
(e.g. all concrete/asphalt paving and hard scape work is complete), and (iii)
Seller is diligently prosecuting the completion of landscaping. Upon Buyer's
request, if a certificate of shell completion or similar certification is
available from the City of Sunnyvale in connection with the Improvements,
without incurring any additional cost or causing delays to the Improvements or
Buyer Improvements, Seller shall use commercially reasonable efforts to obtain
such certification after completion of the Improvements and deliver a copy to
Buyer.

                  7. Buyer Delays. If substantial completion of the Improvements
is delayed due to any of the following (collectively, "Buyer Delays"), then the
delay shall be included in the Milestone Delay Extension and the Purchase Price
shall be subject to adjustment pursuant to 

   26

Section 6(d) of the Purchase Agreement: (i) Buyer's failure to timely submit any
items required by this Work Letter, including, without limitation, the space
plan, supporting drawings and specifications and pallet of interior colors and
finishes; (b) Buyer's requested changes to the Improvements pursuant to any
Change Order(s); or (c) Buyer's failure to comply with Seller's contractor's
schedule. No Buyer Delay shall be deemed to have occurred unless and until
Seller has given written notice to Buyer specifying the action or inaction which
Seller contends constitutes a Buyer Delay. If such action or inaction is not
cured within one (1) business day after Buyer's receipt of such notice, then a
Buyer Delay, as set forth in such notice, shall be deemed to have occurred
commencing as of the date Buyer received such notice and continuing for the
number of days the substantial completion of the Improvements was in fact
delayed as a direct result of such action or inaction.

                  8. Seller Delay. The term "Seller Delay" as used in this Lease
or this Work Letter shall mean the extent of any delay in the design or
construction of the Buyer Improvements which is due to the following: (1) delay
in the giving of authorizations or approvals by Seller beyond the time periods
provided for herein or in the Lease; (2) delay attributable to the refusal of
Seller, its agents or contractors to permit Buyer, its agents or contractors,
access to and use of the Building and any Building facilities or services after
the Initial Buyer Work Date; (3) delay attributable to Seller giving Buyer
incorrect or incomplete Building requirements or Seller Plans, or revisions made
to such Seller Plans subsequent to the delivery of such items to Buyer; and (4)
failure of Seller to deliver Seller's Plans to Buyer on or before July 1, 1998.
No Seller Delay shall be deemed to have occurred unless and until Buyer has
given written notice to Seller specifying the action or inaction which Buyer
contends constitutes a Seller Delay. If such action or inaction is not cured
within one (1) business day after Seller's receipt of such notice, then a Seller
Delay, as set forth in such notice, shall be deemed to have occurred commencing
as of the date Seller received such notice and continuing for the number of days
the substantial completion of the Buyer Improvements was in fact delayed as a
direct result of such action or inaction.

                  9. Force Majeure Events. The term "Force Majeure Events," as
used in the Lease or this Work Letter shall mean any delay in the completion of
the Improvements which is attributable to any: (1) actual delay or failure to
perform by the applicable party attributable to any strike, lockout or other
labor or industrial disturbance (whether or not on the part of employees of
either party hereto), civil disturbance, future order claiming jurisdiction, act
of the public enemy, war, riot, sabotage, blockade, embargo, inability to secure
customary materials, supplies, or labor through ordinary sources by reason or
regulation or order of any governmental or regulatory body; (2) delay
attributable to lightning, earthquake, fire, storm, hurricane, tornado, flood,
washout, rain, severe weather, explosion, or any other similar industry-wide or
area-wide cause beyond the reasonable control of the party from whom performance
is required, or any of its contractors or other representatives. Except as
specifically limited in this Work Letter, any prevention, delay or stoppage due
to any Force Majeure Event shall excuse the performance of the party affected
for a period of time equal to any such prevention, delay or stoppages (except
the obligations of either party to pay money, other than rent, pursuant to this
Lease). No Force Majeure Event shall be deemed to have occurred unless and until
the party claiming such Force Majeure Event has provided written notice to the
other party specifying the action or inaction 


   27

that such notifying party contends constitutes a Force Majeure Event within five
(5) business days of the occurrence of such event.

                  10. Billing. Buyer shall pay to Seller all amounts payable by
Buyer within thirty (30) days after billing by Seller. Bills may be rendered
during the progress of the work so as to enable Seller to pay its general
contractor, architect or engineers without advancing Seller's funds for changes
to the Base Building Improvements, though such progress billings shall only be
based on the extent to which the work is completed.

                  11. Insurance. During the course of construction, Seller shall
require its contractors and architects to obtain and maintain in force Broad
Form Comprehensive General Liability insurance (including, without limitation,
insurance against completed operations liability for losses occurring within
three (3) years after the completion of the Work) with coverage for explosion,
collapse, and underground damage, against claims arising out of bodily injury,
personal injury, or death and from damage to or destruction of property of
others, including, without limitation, loss of use thereof, and including,
without limitation, the liability of Seller or the applicable contractor or
architect arising out of the activities of all subcontractors, and each of them,
with a combined single limit of not less than One Million Dollars ($1,000,000)
for any one accident and/or occurrence and/or series of accidents or occurrences
arising out of any one event. Such insurance shall include Broad Form Property
Damage and Independent Contractors Coverage. Such insurance shall be primary and
not subject to any contribution from any insurance carried by Seller.

                  12. Buyer's Improvements. In the event that Buyer wishes to
commence constructing additional improvements within the Improvements to be
constructed by Seller ("Buyer's Improvements") prior to substantial completion
of the Improvements by Seller, the terms and conditions of this paragraph 12
shall apply. Buyer shall use Devcon Construction as its general contractor for
the Buyer Improvements or some other contractor with an equivalent reputation
and bonding capability reasonably approved by Seller ("Buyer's Contractor").
Buyer shall direct and authorize Buyer's Contractor to keep Seller fully
informed of the construction process for the Buyer Improvements and to provide
Seller with access to all documentation and other information in Buyer's
Contractor's possession or control regarding construction of the Buyer
Improvements, provided that Seller shall not be obligated to monitor or inspect
construction of the Buyer Improvements or any information in connection
therewith.

                  All Buyer Improvements shall be constructed by Buyer's
Contractor. Installation of all Buyer Improvements shall be coordinated with
Seller's contractor's schedule for the Base Building Improvements, and shall be
handled in such a manner as to maintain harmonious labor relations and not
interfere with or delay the work of Seller's contractors. In addition, at
Seller's request all Buyer Improvements shall be constructed using union labor.
All Buyer Improvements furnished and installed by Buyer shall not cause Seller's
contractor to be dependent upon Buyer's work in order for Seller's contractor to
complete his work. Buyer's contractors, subcontractors and labor shall be
subject to approval by Seller which approval shall not be unreasonably withheld
or delayed and shall be subject to the reasonable administrative supervision of
Buyer's general contractor and reasonable rules of the site. Buyer shall give


   28

Seller full access and entry to the Premises in order to complete the Base
Building Improvements. Buyer shall not be charged any fee for Seller's review of
the plans, drawings and specifications or any oversight of the construction of
the Buyer Improvements.

                  Buyer shall keep the Property free and clear of all lien
claims arising in connection with Buyer's Improvements. Any delay experienced by
Seller as the result of Buyer's construction of Buyer's Improvements shall
constitute a Buyer's Delay (subject to the notice and cure provisions of section
7 above) for the purposes of this work letter. In the event the Purchase
Agreement is terminated by Buyer pursuant to the terms and conditions thereof,
except due to Seller's intentional breach at the election of Seller, Buyer shall
immediately remove any and all of Buyer's Improvements that Seller reasonably
determines to be of no value or of negative value in connection with the use of
the Property by Seller; provided, however, at any time prior to commencement of
construction of Buyer's Improvements, Buyer may submit to Seller its plans and
specifications for Buyer's Improvements and request that Seller designate in
writing within fifteen (15) days from receipt of such written request, which
portion of the proposed Buyer's Improvements meet the foregoing standard
requiring removal. Seller shall have no obligation to pay Buyer for any of
Buyer's Improvements in the event of termination of the Agreement for any reason
whatsoever.

         continue to be paid to the Seller in accordance with the terms of the
         Lease unless and until the Buyer is notified otherwise in writing by
         Lender or its successors or assigns. Buyer is hereby authorized and
         directed by Seller to comply with any written direction of Lender
         concerning payment of Rent and no such compliance will give rise to any
         default by Buyer under the Lease.

         It is particularly noted that:

                  modified in any of its terms, or consent be given to the

                  more than one (1) month in advance.

                  (b) The interest of the Seller in the Lease has been assigned

                            INDEMNIFICATION AGREEMENT


                  This Indemnification Agreement is executed as of June 15, 1998
by and between Network Appliance, Inc., a Delaware Corporation ("Network") and
495 Java Drive Associates, L.P., a California limited partnership ("Java").

                  1.  Recitals.

                      a. Java owns the property located at 495 Java Drive,
Sunnyvale, California ("Property").

                      b. Java is in the process of constructing a four story
building consisting of approximately One Hundred Twenty-Six Thousand Seven
Hundred Sixty (126,760) square feet ("Improvements"). The Improvements are being
constructed by Devcon Construction Company ("Devcon").

                      c. Network and Java have executed that certain Agreement
Of Purchase And Sale dated as of June 11, 1998 for the purchase by Network of
the Property ("Purchase Agreement").

                      d. The capitalized terms not otherwise defined herein
shall have the meanings given in the Purchase Agreement.

                      e. Network wishes to review the plans and specifications
for the Improvements to consider changes therein. Under the terms and conditions
of the Purchase Agreement the additional costs of changes are to be borne by
Network. In order to minimize the additional costs associated with such changes
Network has determined that it would be to its advantage to cause Devcon to stop
construction as of the date hereof and to do only such construction as Network
shall authorize.

                      f. Java is willing to allow Network to stop the Devcon
construction and limit its construction to only those portions of the work
authorized by Network in accordance herewith if, and only if, Network
indemnifies Java on the terms and conditions of this Indemnity Agreement for the
costs associated therewith.

                  2. Devcon Construction. Java shall instruct Devcon to stop
construction as of June 16, 1998 and to limit its construction to only the
portions of work authorized by Network (collectively "Stop Work Notice") until
the earlier of (i) written notice delivered by Network to Java notifying Java
that it wishes to withdraw the Stop Work Notice or (ii) written notice by Java
delivered to Network that it has withdrawn the Stop Work Notice following
termination of the Purchase Agreement or after September 14, 1998.

                  3. Indemnification. Network shall be obligated to pay Java the
following costs and expenses associated with the Stop Work Notice:

                  (a) All increased costs of construction of the Improvements


   49

                  charged by Devcon in connection with the Stop Work Notice as
                  evidenced by appropriate invoices and supporting information
                  supplied by Devcon. Java agrees to cooperate with Network in
                  reviewing and approving such charges.

                  (b) The sum of $2,323 per day for the period that substantial
                  completion of the Improvements is delayed by the effect of the
                  Stop Work Notice as determined by Devcon and reasonably
                  approved by Java. Unless and until substantial completion of
                  the Improvements occurs it shall be presumed that the number
                  of days of delay caused by the Stop Work Notice shall be the
                  number of days from June 16, 1998 until the day proceeding the
                  date Devcon commences pouring foundations (ie the same stage
                  of construction that existed on June 16, 1998) ("Presumed
                  Delay Period"). If the purchase and sale contemplated by the
                  Purchase Agreement fails to occur for any reason whatsoever,
                  the number of days of delay shall be the Presumed Delay
                  Period. If the purchase and sale contemplated by the Purchase
                  Agreement is completed the number of days of delay for the
                  computation required by this sub-paragraph (b) shall be the
                  lesser of (i) the Presumed Delay Period or (ii) the number of
                  days beyond March 17, 1999 that substantial completion of the
                  Improvements (as defined in the Purchase Agreement) occurs.

                  4. Payment. Unless and until the Purchase Agreement is
terminated or the Closing Date arrives and Close of Escrow is not completed on
the Closing Date the amounts that Network is obligated to pay pursuant to this
Indemnification Agreement shall be treated as a Change Order under the Purchase
Agreement and credited to the first $3,000,000 of Change Orders to be financed
by Java and which are to result in an adjustment to the Purchase Price at Close
of Escrow. In the event the Purchase Agreement is terminated for any reason
whatsoever and/or the Closing Date arrives and Network fails to purchase the
Property for any reason whatsoever, the amounts payable by Network to Java
hereunder shall be due and payable within ten (10) days written notice given
pursuant to the notice procedure set forth in the Purchase Agreement.

                  5. Attorneys fees; Arbitration. In the event of any litigation
or arbitration regarding the rights and obligations under this Agreement the
prevailing party shall be entitled to recover, in addition to damages,
reasonably attorney's fees, expert witness fees and court costs. Any controversy
or claim arising out of this Agreement shall be settled by arbitration in
accordance with the rules of the American Arbitration Association for the
arbitration of commercial disputes, and judgement on the award rendered by the
Arbitrator(s) may be entered in any court having jurisdiction. the prevailing
party in such arbitration shall be entitled to attorney's fees and costs.

                  6. Separate and Independent Obligations. The obligations of
Network are entirely separate and independent of any and all of the rights and
obligations of the parties under the Purchase Agreement or any other agreement
between the parties hereto.

                  IN WITNESS WHEREOF the parties hereto have executed this
Indemnity Agreement as of the date and year set forth above.

about the Premises for or in connection with any operations of Lessee, any
alteration, improvement or repairs or additions that Lessee may make or permit
or cause to be made, or any work or construction by, for or permitted by Lessee
on or about the Premises, and at all times promptly and fully to pay and
discharge any and all claims upon which any such lien may or could be based, and
to save and hold Lessor and Lessor's Interest in the Premises free and harmless
of and from any and all such liens and claims of liens and suits or other
proceedings pertaining thereto.

Section 17.2 No Affect on Lessor's Interests. No mechanics' or material
suppliers' liens or mortgages, deeds of trust, or other liens of any character
whatsoever created or suffered by Lessee shall in any way, or to any extent,
affect the interest, right or title of Lessor in and to the Premises or the
Improvements.

         Section 17.3 Lessor's Right to Cause Release of Liens. If Lessee shall
not within ten (10) days following the imposition of any such lien which is not
being contested by Lessee in accordance with Article 18 below, cause the lien to
be released of record by payment or posting of a proper bond, Lessor shall have
the right but not the obligation to cause the same to be released by such means
as Lessor shall deem appropriate and the amount paid by Lessor together with all
expenses incurred by Lessor in connection therewith (including without
limitation reasonable attorneys' fees and expense), plus interest at the
Interest Rate from the date of payment by Lessor, shall be Additional Rental,
immediately due and payable by Lessee to Lessor upon demand.

ARTICLE 18. RIGHT TO CONTEST LIENS

                  Lessee shall have the right to contest, in good faith, the
amount or validity of any lien of the nature described in Section 17.1 above,
provided that Lessee shall give Lessor written notice of Lessee's intention to
do so within ten (10) days after the recording of such lien, and provided
further, that Lessee shall, at its expense, defend itself and Lessor against the
same and shall pay and satisfy any adverse judgment that may be rendered thereon
before the enforcement thereof against the Premises.

ARTICLE 19. COMPLIANCE WITH LAWS; INSURANCE REQUIREMENTS

Section 19.1 Compliance with Applicable Laws. Lessee, at Lessee's cost and
expense, shall comply with all Applicable Laws. Any work or installations made
or performed by or on behalf of Lessee or any person or entity claiming through
or under Lessee in order to conform the Premises to Applicable Laws shall be
subject to and performed in compliance with the provisions of Article 13. Lessee
shall give Lessor immediate written notice of any violation of Applicable Laws
known to Lessee and, at its sole cost and expense, Lessee shall immediately
rectify any such violation. Without in any way limiting the generality of the
foregoing obligation of Lessee, Lessee shall be solely responsible for
compliance with, and shall make or cause to be made all such improvements and
alterations to the Premises (including, without limitation, removing such
barriers and providing such alternative services) as shall be required by, the
Americans with Disabilities Act (42 USC section 12101 et seq.), as the same may
be amended from time to time, and any similar or successor laws, and with any
rules or regulations promulgated thereunder. Lessee's liability shall be primary
and Lessee shall indemnify Lessor in accordance with Article 22 in the event of
any failure or alleged failure of Lessee to comply or to cause the Improvements
to comply with said laws and rules and regulations.

Section 19.2 Compliance with Insurance Requirements. Lessee shall not do
anything, or permit anything to be done, in or about the Premises that would:
(i) invalidate or be in conflict with the provisions of any fire or other
insurance policies covering the Premises or any property located therein, or
(ii) result in a refusal by insurance companies of good standing to insure the
Premises or any such property in amounts required hereunder. Lessee, at Lessee's
expense, shall comply with all rules, orders, regulations or requirements of the
American Insurance Association (formerly the National Board of Fire
Underwriters) and with any similar body that shall hereafter perform the
function of such Association.

ARTICLE 20. HAZARDOUS SUBSTANCES

Section 20.1 Lessee Indemnity. Except for Lessor's obligations pursuant to
Section 4.1 above, Lessee releases Lessor from any liability for, waives all
claims against Lessor and shall indemnify, defend and hold harmless Lessor, its
employees, partners, agents, subsidiaries and affiliate organizations against
any and all claims, suits, loss, costs (including costs of investigation, clean
up, monitoring, restoration and reasonably attorney fees), damage or liability,
whether foreseeable or unforeseeable, by reason of property damage (including
diminution in the value of the property of Lessor), personal injury or death
directly arising from or related to Hazardous Substances released, manufactured,
discharged, disposed, used or stored on, in, or under the Land or Premises
during the initial Term and any extensions of this Lease by Lessee or its
employees, agents or contractors. The provisions of this Lessee Indemnity
regarding Hazardous Substances shall survive the termination of the Lease.


   18

Section 20.2 Lessor Indemnity. Lessor releases Lessee from any liability for,
waives all claims against Lessee and shall indemnify, defend and hold harmless
Lessee, its officers, employees, and agents to the extent of Lessor's interest
in the Project, against any and all actions by any governmental agency for clean
up of Hazardous Substances on or under the Land (including, without limitation,
any groundwater contamination) including costs of legal proceedings,
investigation, clean up, monitoring, and restoration, including reasonable
attorney fees and Lessor also releases Lessee from any liability for, waives all
claims against Lessee and shall indemnify, defend and hold harmless Lessee, its
officers, employees and agents from and against any and all liability and
actions for damages to property instituted by any third parties, if, and to the
extent, in either case, arising from the presence of Hazardous Substances on, in
or under the Land or Premises, except to the extent caused by the release,
disposal, use or storage of Hazardous Substances in, on or about the Premises by
Lessee, its employees, agents, sublessees, assignees, or contractors. The
provisions of this Lessor Indemnity regarding Hazardous Substances shall survive
the termination of the Lease.

Section 20.3 Lessee Covenants. Lessee has informed Lessor that, except for very
immaterial amounts of toxic materials incidental to office use (e.g. copier
toner, typical janitorial cleaning materials, petroleum products in cars),
Lessee will not use any Hazardous Substances within the Project and shall comply
with any applicable Laws to the extent that it does. Lessee shall immediately
notify Lessor if and when Lessee learns or has reason to believe there has been
any release of Hazardous Substances in, on or about the Project during the Term.

Section 20.4 Right to Remediate. Should Lessee fail to perform or observe any of
its obligations or agreements pertaining to Hazardous Substances or
Environmental Requirements, then Lessor shall have the right, but not the duty,
without limitation of any other rights of Lessor hereunder, to enter the
Premises personally or through its agents, consultants or contractors and
perform the same. Lessee agrees to indemnify Lessor for the costs thereof and
liabilities therefrom as set forth above in this Section 20.

ARTICLE 21. INSURANCE

Section 21.1 Required Insurance. At all times during the Term and at its sole
cost and expense, Lessee shall obtain and keep in force for the benefit of
Lessee and Lessor the following insurance:

                  (a) Fire and casualty insurance on all Improvements. The
amount of such insurance shall be the Full Insurable Replacement Value. All such
policies shall specify that proceeds shall be payable whether or not any
improvements are actually rebuilt. Each such policy shall include an endorsement
protecting the named and additional insureds against becoming a co-insured under
the policy. Lessee hereby waives as against Lessor any and all claims and
demands, of whatever nature, for damages, loss or injury to the Improvements and
to the property of Lessee in, upon or about the Premises caused by or resulting
from fire and/or other perils, construction defects and/or other events or
happenings.

                  "Full Insurable Replacement Value" means 100% of the actual
costs to replace the Improvements (without deduction for depreciation but with
standard exclusions such as foundations, excavations, paving and landscaping, as
applicable to specific perils), including the 


   19

costs of demolition and debris removal and including materials and equipment not
in place but in transit to or delivered to the Premises. The Full Insurable
Replacement Value initially shall be determined at Lessee's expense by an
appraiser or one of the insurers, selected by Lessee and acceptable to Lessor.
Lessor or Lessee may at any time, but not more frequently than once in any
twelve (12) month period, by written notice to the other, require the Full
Insurable Replacement Value to be redetermined, at Lessee's expense, by an
appraiser or one of the insurers, selected by Lessee and reasonably acceptable
to Lessor. Lessee shall maintain coverage at the current Full Insurable
Replacement Value throughout the Term.

                  (b) Insurance against loss of rental from the Premises, under
a rental value insurance policy, or against loss from business interruption
under a business interruption policy, covering risk of loss due to causes
insured against under subsection (a), in an amount not less than twelve months
of projected rental income from the Premises.

                  (c) Worker's Compensation Insurance in the amounts and
coverages required under worker's compensation, disability and similar employee
benefit laws applicable to the Premises, with all elective employment covered on
a voluntary basis where permissible, and Employer's Liability Insurance with
limits not less than $500,000 or such higher amounts as may be required by law.

                  (d) Comprehensive general liability through one or more
primary and umbrella liability policies against claims, including but not
limited to, bodily injury and property damage occurring on the Premises or the
streets, curbs or sidewalks adjoining the Premises, with such limits as may be
reasonably required by Lessor from time to time, but in any event not less than
Ten Million Dollars ($10,000,000), combined single limit and annual aggregate
for the Premises. Such insurance shall insure the performance by Lessee of the
indemnity agreements contained in this Lease. If any governmental agency or
department requires insurance or bonds with respect to any proposed or actual
use, storage, treatment or disposal of Hazardous Substances by Lessee or any
sublessee, tenant, or licensee of Lessee, Lessee shall be responsible for such
insurance and bonds and shall pay all premiums and charges connected therewith;
provided, however, that this provision shall not and shall not be deemed to
modify the provisions of Article 20 hereof.

                  Such insurance shall (i) delete any employee exclusion on
personal injury coverage; (ii) include employees as additional insureds; (iii)
provide for blanket contractual coverage, including liability assumed by and the
obligations of Lessee under Article 22 for personal injury, death and/or
property damage; (iv) provide Products and Completed Operations and Independent
Contractors coverage and Broad Form Property Damage liability coverage without
exclusions for collapse, explosion, demolition, underground coverage and
excavating, including blasting; (v) provide aircraft liability coverage, if
applicable, and automobile liability coverage for owned, non-owned and hired
vehicles; (vi) provide liability coverage on all mobile equipment used by
Lessee; and (vii) include a cross liability endorsement (or provision)
permitting recovery with respect to claims of one insured against another. Such
insurance shall insure against any and all claims for bodily injury, including
death resulting therefrom, and damage to or destruction of property of any kind
whatsoever and to whomever belonging and arising from Lessee's operations
hereunder and whether such operations are performed by Lessee or any of its
contractors, subcontractors, or by any other person.


   20

                  (e) An environmental impairment liability policy with such
limits as may be appropriate given the nature of Lessee's operations on the
Premises.

                  (f) All other insurance that Lessee is required to maintain
under Applicable Laws.

Section 21.2 Policy Form and General.

                  (a) All of the insurance policies required under this Lease,
including without limitation, under the provisions of Article 13 and this
Article 21, and all renewals thereof shall be issued by one or more companies of
recognized responsibility, authorized to do business in California with a
financial rating of at least a Class A--VII (or its equivalent successor)
status, as rated in the most recent edition throughout the Term of Best's
Insurance reports (or its successor, or, if there is no equivalent successor
rating, otherwise reasonably acceptable to Lessor). Any loss adjustment or
disposition of insurance proceeds by the insurer shall require the written
consent of Lessor for losses in excess of One Hundred Thousand Dollars
($100,000.00). All property insurance hereunder shall name Lessor as an
additional insured and all liability insurance shall name as additional insureds
Lessor, and its directors, trustees, officers, agents, and employees, and such
other parties as Lessor reasonably may request. Any deductibles or self
insurance retention for any of the foregoing insurance must be agreed to in
advance in writing by Lessor, which consent shall not be unreasonably withheld
or delayed; all deductibles and self insurance retention shall be paid by
Lessee. All insurance of Lessee shall be primary coverage.

                  (b) Each policy of property insurance and all other policies
of insurance required by the provisions of this Lease, shall be made expressly
subject to the provisions of this Article 21 and shall provide that Lessee's
insurers shall waive any right of subrogation against Lessor. All policies
provided for herein expressly shall provide that such policies shall not be
canceled, terminated or altered without thirty (30) days' prior written notice
to Lessor. Each policy, or a certificate of the policy executed by the insurance
company evidencing that the required insurance coverage is in full force and
effect, shall be deposited with Lessor on or before the date of this Lease,
shall be maintained throughout the Term, and shall be renewed, not less than
thirty (30) days before the expiration of the term of the policy. Except for
specific provisions described herein, no policy shall contain any provisions for
exclusions from liability and no exclusion shall be permitted in any event if it
conflicts with any coverage required hereby, and, in addition, no policy shall
contain any exclusion from liability for personal injury or sickness, disease or
death or which in any way impairs coverage under the contractual liability
coverage described above.

                  (c) If either party shall at any time deem the limits of any
of the insurance described in this Lease then carried or required to be carried
to be either excessive or insufficient, or if Lessee shall determine that any
form, scope, or type of insurance required hereunder is not generally available
in the marketplace at reasonable cost, the parties shall endeavor to agree upon
the proper and reasonable limits and terms for such insurance then to be carried
and such insurance shall thereafter be carried with the limits and terms thus
agreed upon until further change pursuant to the provisions of this subsection.
If the parties shall be unable to agree on the proper and reasonable limits and
terms for such insurance, then such limits and terms shall be determined
pursuant to the provisions of Article 37. The decision of the appraiser 


   21

as to such limits and terms for such insurance then to be carried shall be
binding upon the parties and such insurance shall be carried with the limits and
terms as thus determined until such limits shall again be changed pursuant to
the provisions of this subsection. The expenses of such determination shall be
borne equally between Lessor and Lessee.


ARTICLE 22. INDEMNITY AND RELEASE

                  Lessee shall indemnify, protect, defend and save and hold
harmless Lessor and the Premises from and against, and reimburse Lessor for, any
and all claims, demands, losses, damages, costs, liabilities, causes of action
and expenses, including, without limitation, reasonable attorneys' fees and
expenses, incurred in connection with or arising, in whole or in part, in any
way out of this Lease, any default by Lessee in the observance or performance of
any of the terms, covenants or conditions of this Lease on Lessee's part to be
observed or performed, the use, occupancy or manner of use or occupancy of the
Premises by Lessee or any sublessee, licensee, or any other person or entity,
the conduct or management of any work or thing done in or on the Premises, the
design, construction, maintenance, or condition of any Improvements, the
condition of the Premises, any actual or alleged acts, omissions, or negligence
of Lessee or of the sublessees, contractors, agents, servants, employees,
visitors or licensees of Lessee, in, on or about the Premises or other of
Lessor's lands, and any accident or other occurrence on the Premises from any
cause whatsoever, except to the extent caused solely by the gross negligence or
willful misconduct of Lessor.

                  In case any claim, action or proceeding be brought, made or
initiated against Lessor relating to any of the above described events, acts,
omissions, occurrences, or conditions, Lessee, upon notice from Lessor, shall at
its sole cost and expense, resist, or defend such claim, action or proceeding by
attorneys approved by Lessor.

                  Lessor shall not be responsible for, and Lessee hereby waives
any and all claims and causes of action whatsoever of any kind or nature against
Lessor for, any injury, loss, damage or liability to any person or property in
or about the Premises or in any way connected with the Premises or this Lease,
from any cause whatsoever (other than caused solely by the gross negligence or
willful misconduct of Lessor).

                  The provisions of this Article 22 shall survive any
termination of this Lease. The provisions of Article 21 (Insurance) shall not
limit in any way Lessee's obligations under this Article 22.


   22

ARTICLE 23. APPROPRIATION, DAMAGE OR DESTRUCTION

Section 23.1 No Termination, No Affect on Rental Obligation. No Appropriation
nor any loss or damage by fire or other cause resulting in either partial or
total destruction of the Premises, the Improvements or any other property on the
Premises shall,

Section 23.2 Determination of Award. The amount of the Award due to Lessor and
Lessee as a result of Appropriation shall be separately determined by the court
having jurisdiction of such proceedings based on the following: Lessor shall be
entitled to that portion of the Award attributable to the value of the fee
interest in the Premises (or portion thereof subject to Appropriation, in case
of a partial Appropriation) subject to this Lease, and to the value of Lessor's
reversionary interest in the Improvements (or portion thereof subject to
Appropriation, in case of a partial Appropriation), as determined by the court;
Lessee shall be entitled to that portion of the Award attributable to the value
of Lessee's leasehold interest in the Premises (or portion thereof subject to
Appropriation, in case of a partial Appropriation) and to the value of Lessee's
interest in the Improvements (or portion thereof subject to Appropriation, in
case of a partial Appropriation), as determined by the court.

ARTICLE 24. ASSIGNMENT

Section 24.1 Assignment. Prior to completion of construction of the Initial
Improvements, any assignment by Lessee of its leasehold estate shall not release
Lessee from its obligations hereunder and such assignments shall be subject to
the consent of Lessor, provided, however, Lessee shall have the right to assign
its interest hereunder to a financing entity in connection with a synthetic
lease transaction without the prior written consent of Lessor.

Section 24.2 Assumption in Writing. No assignment by Lessee shall become
effective unless and until the assignee executes and delivers to Lessor a
written form of assignment in which the assignee assumes and agrees to perform
and observe all covenants and conditions to be performed and observed by Lessee
under this Lease for the period from and after the date of the assignment.

ARTICLE 25. SUBLETTING

Section 25.1 Conditions to Subletting. Lessee may enter into Subleases in
respect of the Premises without Lessor's consent. No Sublease shall relieve
Lessee from the performance of any of its obligations under this Lease. No
Sublease shall extend beyond the Term of this Lease. Each Sublease shall be
subject to and subordinate to the terms, covenants and conditions of this Lease
and the rights of Lessor hereunder.

ARTICLE 26. LEASEHOLD MORTGAGES


   23

Section 26.1 Leasehold Mortgage. Notwithstanding the provisions of Article 24
regarding Transfer of this Lease, but subject to the provisions of this Article
26, Lessee shall have the right at any time and from time to time to encumber
the entire (but not less than the entire) leasehold estate created by this Lease
and Lessee's interest in the Improvements by a mortgage, deed of trust or other
security instrument (any such mortgage, deed of trust, or other security
instrument that satisfies the requirements of this Article 26 being herein
referred to as a "Leasehold Mortgage") to secure repayment of one or more loans
(and associated obligations) made to Lessee.

                  Lessee shall deliver to Lessor promptly after execution by
Lessee a true and verified copy of any Leasehold Mortgage, and any amendment,
modification or extension thereof, together with the name and address of the
owners and holder thereof.

                  In no event shall any interest of Lessor in the Premises,
including without limitation, Lessor's fee interest in the Premises or
reversionary interest in the Improvements or interest under this Lease, be
subject or subordinate to any lien or encumbrance of any mortgage, deed of trust
or other security instrument.

Section 26.2 Agreement Regarding the Leasehold Mortgage. During the continuance
of any Leasehold Mortgage until such time as the lien of any Leasehold Mortgage
has been extinguished, and if a true and verified copy of such Leasehold
Mortgage shall have been delivered to Lessor together with a written notice of
the name and address of the holder thereof:

                  (a) Lessor shall not agree to any termination nor accept any
surrender of this Lease (except upon the expiration of the Term or termination
pursuant to Article 23 hereof and as otherwise provided below with respect to
termination upon an Event of Default), nor shall any material amendment or
modification of this Lease be binding upon the holder of a Leasehold Mortgage
("Lender") or any purchaser in foreclosure from the Lender, unless the Lender
has given its prior written consent to such amendment or modification.

                  (b) The Lender shall have the right, but not the obligation,
at any time prior to termination of this Lease and without payment of any
penalty, to pay all of the Base Monthly Rental and Additional Rental due
hereunder, to provide any insurance and make any other payments, to make any
repairs and improvements and do any other act or thing required of Lessee
hereunder, and to do any act or thing which may be necessary and proper to be
done in the performance and observance of the covenants, conditions and
agreements hereof to prevent the termination of this Lease. All payments so made
and all things so done and performed by the Lender shall be as effective to
prevent a termination of this Lease as the same would have been if made, done
and performed by Lessee instead of by the Lender.

                  (c) Should any Event of Default under this Lease occur, the
Lender shall have thirty (30) days after receipt of notice from Lessor setting
forth the nature of such Event of Default, and, if the default is such that
possession of the Premises is necessary to remedy the default, a reasonable time
after the expiration of such thirty (30) day period, within which to remedy such
default, provided that (i) the Lender shall have fully cured any default in the
payment of any monetary obligations of Lessee under this Lease within such
thirty (30) day period and shall continue to pay currently such monetary
obligations as and when the same are 

   24

due, and (ii) the Lender shall have acquired Lessee's leasehold estate created
hereby or given Lessor written notice that the Lender intends to take action to
acquire Lessee's leasehold estate and commenced foreclosure or other appropriate
proceedings in the nature thereof within such thirty (30) day period or prior
thereto, and shall thereafter diligently and continuously prosecute such
proceedings to completion.

                  (d) An Event of Default under this Lease which in the nature
thereof cannot be remedied by the Lender shall be deemed to be remedied if (i)
within thirty (30) days after receiving written notice from Lessor of such Event
of Default, the Lender shall have acquired Lessee's leasehold estate created
hereby or given Lessor written notice that the Lender intends to take action to
acquire Lessee's leasehold estate and commenced foreclosure or other appropriate
proceedings in the nature thereof, (ii) the Lender shall diligently and
continuously prosecute any such proceedings to completion, (iii) the Lender
shall have fully cured any default in the payment of any monetary obligations of
Lessee under this Lease within such thirty (30) day period and shall thereafter
continue to faithfully perform all such monetary obligations, and (iv) after
gaining possession of the Premises, the Lender shall perform all of the
obligations of Lessee hereunder as and when the same are due and cure any
defaults that are curable by the Lender but that require possession of the
Premises to cure, such cure to be effected within thirty (30) days after gaining
possession, or such longer period of time as is reasonably necessary to effect
such cure using all due diligence.

                  (e) If the Lender is prohibited by any process or injunction
issued by any court or by reason of any action by any court having jurisdiction
of any bankruptcy or insolvency proceedings involving Lessee from commencing or
prosecuting foreclosure or other appropriate proceedings in the nature thereof,
the times specified in subsections (c) and (d) above for commencing or
prosecuting such foreclosure or other proceedings shall be extended for the
period of such prohibition; provided that the Lender shall have fully cured any
default in the payment of any monetary obligations of Lessee under this Lease
and shall continue to pay currently such monetary obligations as and when the
same fall due, and provided further that the Lender shall diligently attempt to
remove any such prohibition.

                  (f) Lessor shall mail to the Lender a duplicate copy by
certified mail of any and all notices that Lessor may from time to time give to
or serve upon Lessee pursuant to the provisions of this Lease.

                  (g) Foreclosure of a Leasehold Mortgage or any sale
thereunder, whether by judicial proceedings or by virtue of any power of sale
contained in the Leasehold Mortgage, or any conveyance of the leasehold estate
created hereby from Lessee to the Lender by virtue or in lieu of foreclosure or
other appropriate proceedings in the nature thereof, shall not require the
consent of Lessor or constitute a breach of any provision of or a default under
this Lease and upon such foreclosure, sale or conveyance, Lessor shall recognize
the Lender, or any other foreclosure sale purchaser or recipient of any deed in
lieu, as Lessee hereunder; provided, (i) the Lender shall have fully complied
with the provisions of this Article 26 applicable prior to gaining possession of
the Premises and the Lender or foreclosure sale purchaser or deed in lieu
recipient, as the case may be, who is to become the Lessee hereunder shall
comply with the provisions of this Article 26 applicable after gaining
possession of the Premises; (ii) the Lender, or foreclosure sale purchaser or
deed in lieu recipient, as the case may be, who is to become the


   25

Lessee hereunder shall be responsible for taking such actions as shall be
necessary to obtain possession of the Premises; and (iii) the Lender, or
foreclosure sale purchaser or deed in lieu recipient, as the case may be, who is
to become the Lessee hereunder shall execute, acknowledge and deliver to Lessor
an instrument in recordable form pursuant to which the Lender or foreclosure
sale purchaser or deed in lieu recipient, as the case may be, expressly assumes
all obligations of the Lessee under this Lease which arise from and after the
date of foreclosure or deed in lieu thereof. If there are two or more Leasehold
Mortgages or foreclosure sale purchasers (whether of the same or different
Leasehold Mortgages), Lessor shall have no duty or obligation whatsoever to
determine the relative priorities of such Leasehold Mortgages or the rights of
the different holders thereof and/or foreclosure sale purchasers. If the Lender
or foreclosure sale purchaser becomes Lessee under this Lease, or under any new
lease obtained pursuant to subsection (h) below, the Lender or foreclosure sale
purchaser shall not be personally liable for the obligations of the Lessee under
this Lease accruing after the period of time that the Lender is the Lessee
hereunder or thereunder.

                  (h) In the event of (a) any rejection of this Lease by Lessee
in any bankruptcy proceeding, or (b) such other termination of this Lease by
reason of a condition which (i) is not known or ascertainable by the parties on
the effective date of the Lender's Leasehold Mortgage, (ii) results from any
applicable state or federal law enacted after the effective date of such
Leasehold Mortgage, and (iii) which would work an inequitable forfeiture upon
the Lender due to the non-curable nature of such condition, Lessor shall,
subject to the terms and conditions of this subsection (h), upon written request
by the Lender to Lessor made within sixty (60) days after such termination,
execute and deliver a new lease of the Premises to the Lender for the remainder
of the term of this Lease with the same covenants, conditions and agreements
(except for any requirements which have been satisfied by Lessee prior to
termination) as are contained herein; provided, however, that Lessor's execution
and delivery of such new lease of the Premises shall be made without
representation or warranty of any kind or nature whatsoever, either express or
implied, including without limitation, any representation or warranty regarding
title to the Premises or the priority of such new lease and Lessor's obligations
and liability under such new lease shall not be greater than if this Lease had
not terminated and the Lender had become the Lessee hereunder. Lessor's delivery
of any Improvements to the Lender pursuant to such new lease shall be made
without representation or warranty of any kind or nature whatsoever, either
express or implied; and the Lender shall take any Improvements "as is" in their
then current condition. Upon execution and delivery of such new lease, the
Lender, at its sole cost and expense, shall be responsible for taking such
action as shall be necessary to cancel and discharge this Lease and to remove
the Lessee named herein and any other occupant from the Premises. Lessor's
obligation to enter into such new lease of the Premises with the Lender shall be
conditioned as follows: (x) the Lender shall have complied with the provisions
of this Article 26 applicable prior to the gaining of possession and shall
comply with the provisions of this Article 26 applicable after gaining
possession of the Premises; (y) if more than one holder of a Leasehold Mortgage
claims to be the Lender and requests such new lease, Lessor shall have no duty
or obligation whatsoever to determine the relative priority of such Leasehold
Mortgages, and in the event of any dispute between or among the holders thereof,
Lessor shall have no obligation to enter into any such new lease if such dispute
is not resolved to the sole satisfaction of Lessor within ninety (90) days after
the date of termination of this Lease; and (z) the Lender shall pay all costs
and expenses of Lessor, including without limitation, reasonable attorneys'
fees, real property transfer taxes and any escrow fees and recording charges,
incurred in 


   26

connection with the preparation and execution of such new lease and any
conveyances related thereto.

ARTICLE 27. LESSOR'S RIGHT OF INSPECTION

                  Lessor shall be entitled, at all reasonable times with advance
written notice to go upon the Premises and the Improvements for the purposes of
(a) inspecting the same, (b) inspecting the performance by Lessee of the terms,
covenants, agreements and conditions of this Lease, (c) posting and keeping
posted thereon Notices of Non-Responsibility for any construction, alteration or
repair thereof, as required or permitted by any law or ordinance, and (d) any
other lawful purposes; provided, however, Lessor's rights hereunder shall not
entitle Lessor to access to the demised premises of any subtenant occupying the
Improvements without the written consent of such subtenant, which consent shall
not be unreasonably withheld.

ARTICLE 28. EVENT OF DEFAULT AND LESSOR'S REMEDIES

Section 28.1 Events of Default. The occurrence of any of the following shall be
an Event of Default on the part of Lessee hereunder:

                  (a) Failure to pay any part of the Base Monthly Rental or
Additional Rental, herein reserved, or any other sums of money that Lessee is
required to pay hereunder at the times or in the manner herein provided, when
such failure shall continue for a period of ten (10) days after written notice
thereof from Lessor to Lessee. No such notice shall be deemed a forfeiture or a
termination of this Lease unless Lessor expressly so elects in such notice.

                  (b) Failure to perform any express or implied nonmonetary
provision of this Lease when, except in the case of any provision which by its
terms provides for no grace period, such failure shall continue for a period of
thirty (30) days, or such other period as is expressly set forth herein, after
written notice thereof from Lessor to Lessee; provided that if the nature of the
default is such that more than thirty (30) days are reasonably required for its
cure, then an Event of Default shall not be deemed to have occurred if Lessee
shall commence such cure within said thirty (30) day period and thereafter
diligently and continuously prosecute such cure to completion and cure. No such
notice shall be deemed a forfeiture or a termination of this Lease unless Lessor
expressly so elects in such notice.

                  (c) The abandonment of the Premises.

                  (d) Lessee shall admit in writing its inability to pay its
debts generally as they become due, file a petition in bankruptcy, insolvency,
reorganization, readjustment of debt, dissolution or liquidation under any law
or statute of any government or any subdivision thereof either now or hereafter
in effect, make an assignment for the benefit of its creditors, consent to or
acquiesce in the appointment of a receiver of itself or of the whole or any
substantial part of the Premises.

                  (e) A court of competent jurisdiction shall enter an order,
judgment or decree appointing a receiver of Lessee or of the whole or any
substantial part of the Premises and such order, judgment or decree shall not be
vacated, set aside or stayed within forty-five (45) days 


   27

after the date of entry of such order, judgment, or decree, or a stay thereof
shall be thereafter set aside.

                  (f) A court of competent jurisdiction shall enter an order,
judgment or decree approving a petition filed against Lessee under any
bankruptcy, insolvency, reorganization, readjustment of debt, dissolution or
liquidation law or statute of the Federal government or any state government or
any subdivision of either now or hereafter in effect, and such order, judgment
or decree shall not be vacated, set aside or stayed within forty-five (45) days
from the date of entry of such order, judgment or decree, or a stay thereof
shall be thereafter set aside.

Section 28.2 Lessor's Remedies. Upon the occurrence of an Event of Default,
Lessor shall have the following rights and remedies:

                  (a) The right to terminate this Lease, in which event Lessee
shall immediately surrender possession of the Premises in accordance with
Article 30, and pay to Lessor all Base Monthly Rental, Additional Rental and
other charges and amounts due from Lessee hereunder to the date of termination.

                  (b) The rights and remedies described in California Civil Code
Section 1951.2, including without limitation, the right to recover the worth at
the time of award of the amount by which the Base Monthly Rental, Additional
Rental and other charges payable hereunder for the balance of the Term after the
time of award exceed the amount of such rental loss for the same period that
Lessee proves could be reasonably avoided, as computed pursuant to subdivision
(b) of said Section 1951.2, and the right to recover any amount necessary to
compensate Lessor for all the detriment proximately caused by Lessee's failure
to perform its obligations under this Lease or which in the ordinary course of
things would be likely to result therefrom which, without limiting the
generality of the foregoing, includes unpaid taxes and assessments, any costs or
expenses incurred by Lessor in recovering possession of the Premises,
maintaining or preserving the Premises after such default, preparing the
Premises for reletting to a new lessee, any repairs or alterations to the
Premises for such reletting, leasing commissions, architect's fees and any other
costs necessary or appropriate either to relet the Premises or to adapt them to
another beneficial use by Lessor and such amounts in addition to or in lieu of
the foregoing as may be permitted from time to time by applicable California
law.

                  (c) The rights and remedies described in California Civil Code
Section 1951.4 that allow Lessor to continue this Lease in effect and to enforce
all of its rights and remedies under this Lease, including the right to recover
Base Monthly Rental, and Additional Rental as they become due, for so long as
Lessor does not terminate Lessee's right to possession. Acts of maintenance or
preservation, efforts to relet the Premises or the appointment of a receiver
upon Lessor's initiative to protect its interest under this Lease shall not
constitute a termination of Lessee's right to possession.

                  (d) The right and power to enter and to sublet the Premises,
to collect rents from all subtenants and to provide or arrange for the provision
of all services and fulfill all obligations of Lessee under the subleases and
Lessor is hereby authorized on behalf of Lessee, but shall have absolutely no
obligation, to provide such services and fulfill such obligations and to incur
all such expenses and costs as Lessor deems necessary in connection therewith.
Lessee 


   28

shall be liable immediately to Lessor for all costs and expenses Lessor incurs
in collecting such rents and arranging for or providing such services or
fulfilling such obligations. Lessor is hereby authorized, but not obligated, to
relet the Premises or any part thereof on behalf of Lessee, to incur such
expenses as may be necessary to effect a relet and make said relet for such term
or terms, upon such conditions and at such rental as Lessor in its sole
discretion may deem proper. Lessee shall be liable immediately to Lessor for all
reasonable costs Lessor incurs in reletting the Premises including, without
limitation, brokers' commissions, expenses of remodeling the Premises required
by the reletting, and other costs. If Lessor relets the Premises or any portion
thereof, such reletting shall not relieve Lessee of any obligation hereunder,
except that Lessor shall apply the rent or other proceeds actually collected by
it as a result of such reletting against any amounts due from Lessee hereunder
to the extent that such rent or other proceeds compensate Lessor for the
nonperformance of any obligation of Lessee hereunder. Such payments by Lessee
shall be due at such times as are provided elsewhere in this Lease, and Lessor
need not wait until the termination of this Lease, by expiration of the Term
hereof or otherwise, to recover them by legal action or in any other manner.
Lessor may execute any lease made pursuant hereto in its own name, and the
lessee thereunder shall be under no obligation to see to the application by
Lessor of any rent or other proceeds, nor shall Lessee have any right to collect
any such rent or other proceeds. Lessor shall not by any reentry or other act be
deemed to have accepted any surrender by Lessee of the Premises or Lessee's
interest therein, or be deemed to have otherwise terminated this Lease, or to
have relieved Lessee of any obligation hereunder, unless Lessor shall have given
Lessee express written notice of Lessor's election to do so as set forth herein.

                  (e) The right to have a receiver appointed upon application by
Lessor to take possession of the Premises and to collect the rents or profits
therefrom and to exercise all other rights and remedies pursuant to Section
28.2(d).

                  (f) The right to enjoin, and any other remedy or right now or
hereafter available to a lessor against a defaulting lessee under the laws of
the State of California or the equitable powers of its courts, and not otherwise
specifically reserved herein.

ARTICLE 29. LESSOR'S RIGHT TO CURE DEFAULTS.

                  If Lessee shall fail or neglect to do or perform any act or
thing herein provided by it to be done or performed and such failure shall not
be cured within any applicable grace period provided in Article 28, then Lessor
shall have the right, but shall have no obligation, to pay any Imposition
payable by Lessee hereunder, discharge any lien, take out, pay for and maintain
any insurance required under Article 21, or do or perform or cause to be done or
performed any such other act or thing (entering upon the Premises for such
purposes, if Lessor shall so elect), and Lessor shall not be or be held liable
or in any way responsible for any loss, disturbance, inconvenience, annoyance or
damage resulting to Lessee on account thereof, and Lessee shall repay to Lessor
upon demand the entire reasonable cost and expense thereof, including, without
limitation, compensation to the agents, consultants and contractors of Lessor
and reasonable attorneys' fees and expenses. Lessor may act upon shorter notice
or no notice at all if necessary in Lessor's judgment to meet an emergency
situation or governmental or municipal time limitation or otherwise to protect
Lessor's interest in the Premises. Lessor shall not be required to inquire into
the correctness of the amount or validity of any Imposition or lien that may be


   29

paid by Lessor, and Lessor shall be duly protected in paying the amount of any
such Imposition or lien claimed, and, in such event, Lessor shall also have the
full authority, in Lessor's sole judgment and discretion and without prior
notice to or approval by Lessee, to settle or compromise any such lien or
Imposition. Any act or thing done by Lessor pursuant to the provisions of this
Article 30 shall not be or be construed as a waiver of any default by Lessee, or
as a waiver of any term, covenant, agreement or condition herein contained or of
the performance thereof. All amounts payable by Lessee to Lessor under any of
the provisions of this Lease, if not paid when the same become due as in this
Lease provided, shall bear interest at the Interest Rate.

ARTICLE 30. SURRENDER OF THE PREMISES

                  Upon the termination of this Lease, whether at the expiration
of the Term as stated in Article 5 hereof or prior thereto pursuant to any
provision hereof, Lessee shall surrender to Lessor the Premises in good order
and repair, reasonable wear and tear and acts of God casualties excepted. Within
ninety (90) days following the termination of this Lease, Lessor may elect to
require Lessee to demolish the buildings located on the Property. Lessor may
make such election by delivering written notice to Lessee within such 90-day
period. In the event Lessor makes such election, Lessee shall diligently proceed
to demolish the buildings and complete such demolition within a reasonable time,
at no cost to Lessor. Unless Lessor gives written notice of its election to
require Lessee to demolish the improvements in accordance with the foregoing,
all Improvements shall automatically and without further act by Lessor or
Lessee, become the property of Lessor.


                  Any personal property of Lessee that remains on the Premises
after the Termination Date may, at the option of Lessor, be deemed to have been
abandoned by Lessee and may either be retained by Lessor as its property or
disposed of, without accountability, in such manner as Lessor may determine in
its sole discretion.

ARTICLE 31. REPRESENTATIONS AND WARRANTIES OF LESSEE

                  Lessee hereby represents and warrants to Lessor as follows:

                  (a) Lessee is a corporation, partnership, or limited liability
company duly formed and validly existing under the laws of the state of
identified in the Basic Lease Information and is qualified to do business under
the laws of the State of California. Lessee has full corporate power and
authority to enter into and perform its obligations under this Lease and to
develop, construct and operate the Premises as contemplated by this Lease.

                  (b) Lessee has taken all necessary action to authorize the
execution, delivery and performance of this Lease and this Lease constitutes the
legal, valid, and binding obligation of Lessee.

                  (c) Lessee has the right, power, legal capacity and authority
to enter into and perform its obligations under this Lease and no approvals or
consents of any person are required in connection with the execution and
performance of this Lease. The execution and performance of this Lease will not
result in or constitute any default or event that with notice or the lapse of


   30

time or both, would be a default, breach or violation of the organizational
instruments governing Lessee or any agreement or any order or decree of any
court or other governmental authority to which Lessee is a party or to which it
is subject.

ARTICLE 32. NO WAIVER BY LESSOR

                  No failure by Lessor to insist upon the strict performance of
any term, covenant, agreement, provision, condition or limitation of this Lease
or to exercise any right or remedy upon a breach thereof, and no acceptance by
Lessor of full or partial rent during the continuance of any such breach, shall
constitute a waiver of any such breach or of such term, covenant, agreement,
provision, condition or limitation. No term, covenant, agreement, provision,
condition or limitation of this Lease and no breach thereof may be waived,
altered or modified except by a written instrument executed by Lessor. No waiver
of any breach shall affect or alter this Lease but each and every term,
covenant, agreement, provision, condition and limitation of this Lease shall
continue in full force and effect with respect to any other then existing or
subsequent breach.

ARTICLE 33. NO PARTNERSHIP

                  It is expressly understood that neither Lessee nor Lessor is
or becomes, in any way or for any purpose, a partner of the other in the conduct
of its business, or otherwise, or joint venturer or a member of a joint
enterprise with the other, or agent of the other by reason of this Lease or
otherwise. Lessee is and shall be an independent contractor with respect to the
Lease and Premises.

ARTICLE 34. NO DEDICATION

                  This Lease shall not be, nor be deemed or construed to be, a
dedication to the public of the Premises, the areas in which the Premises are
located or the Improvements, or any portion thereof.

ARTICLE 35. NO THIRD PARTY BENEFICIARIES

                  This Lease shall not confer nor be deemed nor construed to
confer upon any person or entity, other than the parties hereto, any right or
interest, including, without limiting the generality of the foregoing, any third
party beneficiary status or any right to enforce any provision of this Lease.

ARTICLE 36. NOTICES

                  Any notice, consent or other communication required or

                  Tel. (408) 367-3200

ARTICLE 37. HOLDING OVER

                  This Lease shall terminate upon the Termination Date and any
holding over by Lessee after the Termination Date shall not constitute a renewal
of this Lease or give Lessee any rights hereunder or in or to the Premises.

ARTICLE 38. MEMORANDUM

                  This Lease shall not be recorded. However, at the request of
either party, the parties hereto shall execute and acknowledge a memorandum
hereof (including Lessee's options under Article 10) in recordable form that
Lessor shall file for recording in the Official Records of Santa Clara County.

ARTICLE 39. ESTOPPEL CERTIFICATE

                  Each of the parties hereto agrees, at any time and from time
to time upon not less than twenty (20) days' prior written request by the other
party (which request must specify that response is required within twenty (20)
days), to execute, acknowledge and deliver to the party making such request, or
to any other Person specified by the requesting party, an estoppel certificate
stating: (a) whether this Lease is in full force and effect and whether such
party has any existing defenses or offsets against the enforcement of this
Lease; (b) whether this Lease has been assigned, modified, supplemented or
amended, and, if so, identifying and describing any such assignment,
modification, supplement or amendment; (c) the date to which Rent has been paid;
(d) whether the party to whom the request is directed knows of any default or
failure to perform conditions on the part of the other party hereunder, and if
so, specifying the nature thereof; and (e) that this Lease, as it may have been
modified, supplemented or amended, represents the entire agreement between the
parties as to this leasing.


   32

                  The failure of either party to issue such a certificate to the
requesting party or other specified Person within said twenty (20) day period
shall constitute an acknowledgment by the party to whom such request is directed
that this Lease is unmodified and in full force and effect and shall constitute,
as to any Person entitled to rely upon such certificate, a waiver of any
defaults that may exist prior to the date of such request. Such certificate
shall act as a waiver of any claim by the party furnishing such certificate to
the extent such claim is based upon facts which are contrary to those asserted
in the certificate but only to the extent the claim is asserted against a bona
fide encumbrancer or purchaser for value without knowledge of facts contrary to
those contained in the certificate and who has acted in reasonable reliance upon
the certificate. Such certificate shall in no event subject the party furnishing
it to any liability whatsoever, notwithstanding the negligent or inadvertent
failure of such party to disclose correct or relevant information.


   33

ARTICLE 40. GENERAL PROVISIONS

Section 40.1 Severability. In case any one or more of the provisions of this
Lease shall for any reason be held to be invalid, illegal or unenforceable in
any respect, such invalidity, illegality or unenforceability shall not affect
any other provision of this Lease, and this Lease shall be construed as if such
invalid, illegal or unenforceable provisions had not been contained herein.

Section 40.2 Headings. Article, Section and subsection headings in this Lease
are for convenience only and are not to be construed as a part of this Lease or
in any way limiting or amplifying the provisions hereof.

Section 40.3 Lease Construed as a Whole. The language in all parts of this Lease
shall in all cases be construed as a whole according to its fair meaning and not
strictly for or against either Lessor or Lessee. The parties acknowledge that
each party and its counsel have reviewed this Lease and participated in its
drafting and therefore that the rule of construction that any ambiguities are to
be resolved against the drafting party shall not be employed nor applied in the
interpretation of this Lease.

Section 40.4 Meaning of Terms. Whenever the context so requires, the neuter
gender shall include the masculine and the feminine, and the singular shall
include the plural, and vice versa. Any reference to a specific sum of money,
shall mean that amount of lawful money of the United States of America that
(except where the specific provision by its terms provides for adjustment to
reflect inflation) is the equivalent in value on the date such determination is
to be made under the relevant provision of this Lease, to the stated amount in
U.S. Dollars in the year of the Commencement Date: i.e. the stated amount
increased by the percentage increase equal to the cumulative percentage increase
in the CPI from January 1 of the year of the Commencement Date, to the date of
determination.

Section 40.5 Attorneys' Fees. In the event of any action or proceeding at law or
in equity between Lessor and Lessee to enforce or interpret any provision of
this Lease or to protect or establish any right or remedy of either party
hereunder, the party not prevailing in such action or proceeding shall pay to
the prevailing party all costs and expenses, including without limitation,
reasonable attorneys' fees and expenses (including attorneys' fees and expenses
of in-house attorneys), incurred therein by such prevailing party and if such
prevailing party shall recover judgment in any such action or proceeding, such
costs, expenses and attorneys' fees shall be included in and as a part of such
judgment.

Section 40.6 Binding Agreement. The terms, covenants and agreements contained in
this Lease shall bind and inure to the benefit of the parties hereto and their
respective successors and assigns.



   34

Section 40.7 Entire Agreement. This instrument, together with the exhibits
hereto, all of which are incorporated herein by reference, constitutes the
entire agreement between Lessor and Lessee with respect to the subject matter
hereof and supersedes all prior offers, negotiations, oral and written. This
Lease may not be amended or modified in any respect whatsoever except by an
instrument in writing signed by Lessor and Lessee.

Section 40.8 Quiet Enjoyment. Lessor agrees that Lessee, upon paying the Base
Monthly Rental, Additional Rental and all other sums due hereunder and upon
keeping and observing all of the covenants, agreement and provisions of this
Lease on its part to be observed and kept, shall, subject to the exceptions and
reservations referred to in Article 3, lawfully and quietly hold, occupy and
enjoy the Premises during the Term without hindrance or molestation by anyone
claiming by, through, or under Lessor.

Section 40.9 Termination Not Merger. The voluntary sale or other surrender of
this Lease by Lessee to Lessor, or a mutual cancellation thereof, or the
termination thereof by Lessor pursuant to any provision contained herein, shall
not work a merger, but at the option of Lessor shall either terminate any or all
existing subleases or subtenancies hereunder, or operate as an assignment to
Lessor of any or all of such subleases or subtenancies.

                  IN WITNESS WHEREOF, Lessor and Lessee have executed this Lease
by proper persons thereunto duly authorized as of the date first above written.

                      (a) Option. Owner hereby grants to Optionee an option
("Option") to purchase the Property from Owner, on all of the terms, covenants
and conditions provided herein.

                      (b) Option Payment. Upon execution of this Agreement
Optionee shall pay, as option consideration, the sum of $4,500,000 to Owner
("Option Payment"); provided, however, if Optionee does not pay the Option
Payment upon execution, Optionee must pay the Option Payment within seven (7)
Business Days and failure to pay by said date shall entitle Owner to either (i)
terminate this Agreement and the Ground Lease or (ii) file suit for payment of
the Option Payment. The Option Payment shall be deposited with the Escrow Agent
upon execution of this Agreement pursuant to escrow instructions approved by
Owner and Optionee. The escrow instructions shall provide that the Escrow Agent
shall deposit the Option Payment in an interest bearing account, pursuant to
investment instructions from Optionee and approved by Owner. All interest earned
on the Option Payment shall be for the account of Optionee. The escrow
instructions shall also provide that the Option Payment shall be released to
Owner upon the earlier of (i) exercise of Optionee's option hereunder, in which
case such Option Payment shall be applied toward the Purchase Price, or (ii) the
expiration of the Option without exercise by Optionee.

                  2. Exercise of Option. Optionee shall be entitled to exercise
the Option at any time during the Exercise Window by delivering written notice
of its unconditional election to exercise the Option to Owner ("Exercise
Notice"), which Exercise Notice, in order to be effective, must be delivered to
Owner during, and prior to the expiration of, the Exercise Window. Upon the
effective exercise of the Option in accordance with the foregoing this Agreement
shall be a bilateral agreement requiring Owner to sell the Property to Optionee
and 


   3

Closing Date on the terms and conditions of this Agreement.

                  3. Purchase Price. Optionee shall pay Owner a purchase price
("Purchase Price") for the Property of Twenty-Three Million Seven Hundred
Forty-Five Thousand Dollars ($23,745,000.00), payable at the Close of Escrow in

                  4. Conditions Precedent. At or before Close of Escrow the
following conditions precedent ("Conditions Precedent") shall be either
satisfied or waived by Optionee as a condition to Optionee's obligation to
proceed with the purchase of the Property:

                      (a) Title. The term "Conditions of Title" shall refer to
those exceptions to title (including, without limitation, Title Company's
standard printed exceptions to title with respect to an ALTA Owner's Extended
Form policy of title insurance (an "ALTA Policy") listed on EXHIBIT B
incorporated herein by reference, the lien for real property taxes not
delinquent, any current assessments (subject to Owner's obligation to pay
delinquent assessments or credit same to the Purchase Price at closing), the
effect of the Lot Line Adjustment and the CC&R's, the effect of the Ground Lease
and any improvements constructed by Lessee thereunder, and any other
encumbrances or matters of title caused or approved in writing by Optionee. On

an American Land Title Association ("ALTA") Extended Title Policy Form B (1970)
for the Property ("ALTA Title Policy"), with a liability limit in the amount of
the Purchase Price and insuring fee title vested in Optionee, and (b)
endorsements to the ALTA Title Policy (i) to provide Optionee with assurance
that the Property is the same as shown on the Survey, (ii) to provide Optionee
with assurance that the Property is contiguous with the property known as 495
Java Drive, and (iii) such other endorsements as Optionee may reasonably
request, including without limitation zoning, tax parcel, access, and owner's
comprehensive (ALTA 100, modified for owner, or equivalent) endorsements
(collectively, the "Endorsements"); provided, however, the availability of such
Endorsements shall not be a Condition Precedent to Optionee's obligation
hereunder. Optionee shall take title to the Property subject to the Conditions
of Title.

                      (b) Survey. Optionee has approved a certified ALTA survey
of the Property prepared by Kier & Wright dated April 15, 1998 ("Survey"). Any
revisions (including certification to Optionee) to the ALTA survey previously
provided to Optionee by Owner which are requested by Optionee shall be at

Optionee its certificate representing and warranting (i) to the best of Owner's
knowledge that there has been no such material adverse change between the

provided herein, Owner shall not incumber, lease, transfer, assign or sell all
or any portion, or interest in, the Property, or enter into any agreement or
contract effecting or relating to the Property without Optionee's prior written
consent, which consent may be withheld in Optionee's sole discretion. Owner
shall be entitled to encumber the Property for the purpose of securing one or
more construction loans. Owner may also implement the Lot Line Adjustment,
record the CC&R's and execute such other contracts (but not contracts or
encumbrances that will be binding upon Optionee or the Property after the Close
of Escrow) as may be necessary or advisable in connection with performing its
obligations hereunder including demolition of the existing improvements.

representations and warranties shall survive the Close of Escrow for a period of
twelve (12) months (at which time these representations and warranties shall
expire):

                      (i) Litigation; Government Action. Except as disclosed to
Optionee in writing, there is no claim, litigation, notice that the Property is
in violation of law, or governmental investigation presently pending with
respect to which Owner has been served with process or other notice thereof or,
to the best of Owner's knowledge (as defined below), otherwise pending or
threatened, against or relating to the Property.

                      (ii) Condemnation. There is presently no pending
condemnation of the Property or any part thereof with respect to which Owner has

                      (iii) Leases. There are no leases or other occupancy

Property. 

                                    (3) To the best of Owner's knowledge, the
Property Documents are all of the documents and reports in Owner's possession
pertaining to Hazardous Materials on or at the Property.

                      (v) Property Documents. To the best of Owner's knowledge
there are no other documents or reports in Owner's possession or under Owner's
control other than the Property Documents, describing the condition of the
Property concerning the presence of Hazardous Materials, the geotechnical
condition of the soils or other like physical condition of the Property as of
the Execution Date; provided, however, the existing improvements to be
demolished and removed by Owner contain asbestos. Owner acknowledges and agrees
that the demolition and removal of the existing improvements including the
asbestos containing materials therein and all costs in connection therewith is
the sole responsibility of Owner.

                      (b) Organization and Authority. Owner is a California
limited partnership validly existing and in good standing under the laws of
California. Owner and has full power to enter into this Agreement and is duly
qualified to transact business in California. The execution, delivery, and
performance of this Agreement have been duly authorized and approved by all
requisite action and the consummation of the transactions contemplated hereby
will be duly authorized and approved by all requisite action of Owner and no
other authorizations or approvals, whether of governmental bodies or otherwise,
will be necessary in order to enable Owner enter into or to comply with the
terms of this Agreement.

                      (c) Binding Effect of Documents. This Agreement and the
other documents to be executed by Owner hereunder, upon execution and delivery
thereof by Owner, will have been duly entered into by Owner, and will constitute
legal, valid and binding obligations of Owner. Neither this Agreement nor
anything provided to be done under this Agreement violates or shall violate any
contract, document, understanding, agreement, or instrument to which Owner is a
party or by which it is bound.

                      (d) "Best Knowledge" Definition. For purposes of this
Section 11, the term "to the best of Owner's knowledge" shall mean the current
actual knowledge of John Mozart and Steve Dostart after usual inquiry in
connection with the operation of the Property. Owner represents that John Mozart
and Steve Dostart are the representatives of Owner with supervisory
responsibilities concerning the Property who would, in the ordinary course of
their responsibilities, receive notice from persons or entities of any of the
matters described in the representations and warranties in this Section 11.

                      (e) "As-Is" Condition; Release and Assumption. If Owner
breaches any representation, warranty, or covenant hereunder prior to Closing
and Optionee closes escrow with knowledge thereof, Optionee shall be deemed to
waive such breach. Except as expressly provided in this Agreement and in Owner's
Closing Certificate, Owner makes no representations or warranties of any kind,
express or implied, written or oral, as to the physical condition of the


   9

Property; the uses of the Property or any limitations thereon, including,
without limitation, zoning, environmental or other laws, regulations or
governmental requirements; the utilities or other physical equipment and
fixtures on the Property, the costs of operating the Property or any other
aspect of the economic operations on the Property; the possibility of future
assessments of charges being levied against the Property or imposed as a
condition to development or construction; or the condition of the soils or
groundwater of the Property. Except as provided herein, Optionee specifically
acknowledges that it is acquiring the Property in an "as-is" condition (as such
term is most broadly construed), in reliance upon its own inspection and
investigation of the Property. Except as expressly provided herein, Owner makes
no representation or warranties with respect to the condition of title to the
Property, and Optionee agrees that it will rely solely on its policy of title
insurance. At closing, and as a condition to Owner's obligations hereunder,
Optionee shall, pursuant to a form of Release and Assumption ("Release and
Assumption") prepared by Owner and delivered to Optionee for approval by
Optionee within ten (10) days after the Execution Date, (1) release Owner from
any and all claims, liability or causes of action (except for the express
representations and warranties herein and in Owner's Closing Certificate to the
extent the same survive closing) in connection with the Property and (2) assume
all of Owner's obligations under any and all laws and regulations pertaining to
the Property (except those accruing prior to Close of Escrow).

         10. Loss by Fire or Other Casualty; Condemnation.

                      (a) Condemnation and General Casualty. Optionee shall be
bound to purchase the Property for the full Purchase Price as required by the
terms hereof, without regard to the occurrence or effect of any damage to or
destruction of any improvements or condemnation of any portion of the Property;
provided, however, at Closing the Purchase Price shall be credited by the amount
of any insurance proceeds or condemnation awards collected by Owner (excluding
proceeds or awards payable directly or indirectly, in respect of any delay in
the receipt of the Purchase Price by Owner) as a result of any such damage or
destruction or condemnation less any monies actually expended by Owner to repair
any damage, plus any deductible amounts attributable to such damage or
destruction, or such proceeds shall be assigned to Optionee if not then
collected.

                      (b) Owner Cooperation. If Owner assigns the proceeds of
any insurance policy to Optionee pursuant to Section 10(a), Owner shall
cooperate with Optionee in presenting and prosecuting the claim with Owner's
insurance carriers, shall follow Optionee's instructions with respect thereto
(except to the extent Owner is advised by counsel that following a particular
instruction would expose Owner to liability, or to the extent Owner would incur
additional cost to follow such instruction which is not paid by Optionee), and
will not settle any such claim without Optionee's written approval.

         11. Successors and Assigns. The terms, covenants, and conditions herein
contained shall be binding upon and inure to the benefit of the successors and
assigns of the parties hereto. Optionee may assign it's rights under this
Agreement to a financing entity in connection with a synthetic lease transaction
without the need for Owner's prior written consent. But no such assignment shall
relieve the assignor from primary liability for its obligations hereunder. Prior
to the acquisition of the Property, Optionee intends to assign Optionee's
interest under this Agreement to an entity (the "Lessor"), who will then lease
all of the acquired portions of the 


   10

property to Optionee, as tenant ("Tenant"), pursuant to a synthetic lease
("Lease") to be executed by Lessor and Tenant, pursuant to which Tenant shall
have the right to construct certain improvements thereon, pursuant to plans and
specifications approved by Lessor and Tenant. The parties acknowledge that (a)
Tenant is intended to be the ultimate occupant and user of the Real Property,
and (b) the improvements to be constructed thereon are being designed for
Tenant's benefit and to Tenant's specifications. Therefore, the parties
acknowledge that Tenant is an intended third party beneficiary of all of Owner's
covenant, representations, warranties and obligations under this Agreement.

         12. Entire Agreement. This Agreement contains all of the covenants,
conditions and agreements between the parties and shall supersede all prior
correspondence, agreements, and understandings, both oral and written. No
provisions of this Agreement may be amended or modified in any manner except by
an agreement in writing duly executed by the parties hereto.

         13. Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of California as applied to agreements
among California residents which are entered into and performed entirely within
California.

         14. Attorneys' Fees; Arbitration.

                      (a) Attorneys' Fees. In the event of any litigation or
arbitration regarding the rights and obligations under this Agreement, the
prevailing party shall be entitled to recover, in addition to damages,
injunctive or other relief, reasonable attorneys' fees expert witness fees, and
court costs.

                      (b) Arbitration of Disputes. ANY CONTROVERSY OR CLAIM
ARISING OUT OF THIS AGREEMENT SHALL BE SETTLED BY ARBITRATION IN ACCORDANCE WITH
THE RULES OF THE AMERICAN

ARBITRATION ASSOCIATION FOR THE ARBITRATION OF COMMERCIAL DISPUTES, AND JUDGMENT

Gentlemen:

         This letter is to confirm that Wells Fargo Bank, National Association
("Bank"), subject to all terms and conditions contained herein, has agreed to
make available to Network Appliance, Inc. ("Borrower") a revolving line of
credit under which Bank will make advances to Borrower from time to time up to
and including July 10, 1999, not to exceed at any time the maximum principal
amount of Five Million Dollars ($5,000,000.00) ("Line of Credit"), the proceeds
of which shall be used to finance Borrower's working capital requirements.


I.       CREDIT TERMS:

         1.       LINE OF CREDIT:

         (a) Line of Credit Note. Borrower's obligation to repay advances under
the Line of Credit shall be evidenced by a promissory note substantially in the
form of Exhibit A attached hereto ("Line of Credit Note"), all terms of which
are incorporated herein by this reference.

         (b) Letter of Credit Subfeature. As a subfeature under the Line of
Credit, Bank agrees from time to time during the term thereof to issue standby
and/or sight commercial letters of credit for the account of Borrower to finance
(each, a "Letter of Credit" and collectively, "Letters of Credit"); provided
however, that the form and substance of each Letter of Credit shall be subject
to approval by Bank, in its sole discretion; and provided further, that the
aggregate undrawn amount of all outstanding Letters of Credit shall not at any
time exceed Five Million Dollars ($5,000,000.00). No Letter of Credit shall have
an expiration date more than ninety (90) days beyond the maturity date of the
Line of Credit. The undrawn amount of all Letters of Credit shall be reserved
under the Line of Credit and shall not be available for borrowings thereunder.
Each Letter of Credit shall be subject to the additional terms and conditions of
the 

   2

Network Appliance, Inc.
July 10, 1998
Page 2


Letter of Credit Agreement and related documents, if any, required by Bank in
connection with the issuance thereof. Each draft paid by Bank under a Letter of
Credit shall be deemed an advance under the Line of Credit and shall be repaid
by Borrower in accordance with the terms and conditions of this letter
applicable to such advances; provided however, that if advances under the Line
of Credit are not available, for any reason, at the time any draft is paid by
Bank, then Borrower shall immediately pay to Bank the full amount of such draft,
together with interest thereon from the date such amount is paid by Bank to the
date such amount is fully repaid by Borrower, at the rate of interest applicable
to advances under the Line of Credit. In such event Borrower agrees that Bank,
in its sole discretion, may debit any demand deposit account maintained by
Borrower with Bank for the amount of any such draft.

         (c) Borrowing and Repayment. Borrower may from time to time during the
term of the Line of Credit borrow, partially or wholly repay its outstanding
borrowings, and reborrow, subject to all of the limitations, terms and
conditions contained herein or in the Line of Credit Note; provided however,
that the total outstanding borrowings under the Line of Credit shall not at any
time exceed the maximum principal amount available thereunder, as set forth
above.


II.      INTEREST/FEES:

         1.(a) Interest. The outstanding principal balance of the Line of Credit
shall bear interest at the rate of interest set forth in the Line of Credit
Note.

           (b) Computation and Payment. Interest shall be computed on the basis
of a 360-day year, actual days elapsed. Interest shall be payable at the times
and place set forth in the Line of Credit Note.

           (c) Unused Commitment Fee. Borrower shall pay to Bank a fee equal to
fifteen one-hundredths percent (0.15%) per annum (computed on the basis of a
360-day year, actual days elapsed) on the average daily unused amount of the
Line of Credit, which fee shall be calculated on a calendar quarter basis by
Bank and shall be due and payable by Borrower in arrears within ten (10) days
after each billing is sent by Bank.

           (d) Collection of Payments. Borrower authorizes Bank to collect all
interest and fees due under the Line of Credit by charging Borrower's demand
deposit account number 4311-790562 with Bank, or any other demand deposit
account maintained by 

   3

Borrower with Bank, for the full amount thereof. Should there be insufficient
funds in any such demand deposit account to pay all such sums when due, the full
amount of such deficiency shall be immediately due and payable by Borrower.


III.  REPRESENTATIONS AND WARRANTIES:

         Borrower makes the following representations and warranties to Bank,
which representations and warranties shall survive the execution of this letter
and shall continue in full force and effect until the full and final payment,
and satisfaction and discharge, of all obligations of Borrower to Bank subject
to this letter.

         1. Legal Status. Borrower is a corporation, duly organized and existing
and in good standing under the laws of the state of California, and is qualified
or licensed to do business in all jurisdictions in which such qualification or
licensing is required or in which the failure to so qualify or to be so licensed
could have a material adverse effect on Borrower.

         2. Authorization and Validity. This letter, the Line of Credit Note,
and each other document, contract or instrument deemed necessary by Bank to
evidence any extension of credit to Borrower pursuant to the terms and
conditions hereof, or now or at any time hereafter required by or delivered to
Bank in connection with this letter (collectively, the "Loan Documents") have
been duly authorized, and upon their execution and delivery in accordance with
the provisions hereof will constitute legal, valid and binding agreements and
obligations of Borrower or the party which executes the same, enforceable in
accordance with their respective terms.

         3. No Violation. The execution, delivery and performance by Borrower of
each of the Loan Documents do not violate any provision of any law or
regulation, or contravene any provision of the Articles of Incorporation or
By-Laws of Borrower, or result in a breach of or constitute a default under any
contract, obligation, indenture or other instrument to which Borrower is a party
or by which Borrower may be bound.

         4. Litigation. There are no pending, or to the best of Borrower's
knowledge threatened, actions, claims, investigations, suits or proceedings by
or before any governmental authority, arbitrator, court or administrative agency
which could have a material adverse effect on the financial condition or
operation of Borrower other than those disclosed by Borrower to Bank in writing
prior to the date hereof.

   4

Network Appliance, Inc.

         5. Correctness of Financial Statement. The financial statement of
Borrower dated January 23, 1998, a true copy of which has been delivered by
Borrower to Bank prior to the date hereof, (a) is complete and correct and
presents fairly the financial condition of Borrower, (b) discloses all
liabilities of Borrower that are required to be reflected or reserved against
under generally accepted accounting principles, whether liquidated or
unliquidated, fixed or contingent, and (c) has been prepared in accordance with
generally accepted accounting principles consistently applied. Since the date of
such financial statement there has been no material adverse change in the
financial condition of Borrower, nor has Borrower mortgaged, pledged, granted a
security interest in or otherwise encumbered any of its assets or properties
except in favor of Bank or as otherwise permitted by Bank in writing.

         6. Income Tax Returns. Borrower has no knowledge of any pending
assessments or adjustments of its income tax payable with respect to any year.

         7. No Subordination. There is no agreement, indenture, contract or
instrument to which Borrower is a party or by which Borrower may be bound that
requires the subordination in right of payment of any of Borrower's obligations
subject to this letter to any other obligation of Borrower.

         8. Permits, Franchises. Borrower possesses, and will hereafter possess,
all permits, consents, approvals, franchises and licenses required and all
rights to trademarks, trade names, patents and fictitious names, if any,
necessary to enable it to conduct the business in which it is now engaged in
compliance with applicable law.

         9. ERISA. Borrower is in compliance in all material respects with all
applicable provisions of the Employee Retirement Income Security Act of 1974, as
amended or recodified from time to time ("ERISA"); Borrower has not violated any
provision of any defined employee pension benefit plan (as defined in ERISA)
maintained or contributed to by Borrower (each, a "Plan"); no Reportable Event,
as defined in ERISA, has occurred and is continuing with respect to any Plan
initiated by Borrower; Borrower has met its minimum funding requirements under
ERISA with respect to each Plan; and each Plan will be able to fulfill its
benefit obligations as they come due in accordance with the Plan documents and
under generally accepted accounting principles.

         10. Other Obligations. Borrower is not in default on any obligation for
borrowed money, any purchase money obligation or 

   5

Network Appliance, Inc.
July 10, 1998
Page 5


any other material lease, commitment, contract, instrument or obligation.

         11. Environmental Matters. Except as disclosed by Borrower to Bank in
writing prior to the date hereof, Borrower is in compliance in all material
respects with all applicable federal or state environmental, hazardous waste,
health and safety statutes, and any rules or regulations adopted pursuant
thereto, which govern or affect any of Borrower's operations and/or properties,
including without limitation, the Comprehensive Environmental Response,
Compensation and Liability Act of 1980, the Superfund Amendments and
Reauthorization Act of 1986, the Federal Resource Conservation and Recovery Act
of 1976, and the Federal Toxic Substances Control Act, as any of the same may be
amended, modified or supplemented from time to time. None of the operations of
Borrower is the subject of any federal or state investigation evaluating whether
any remedial action involving a material expenditure is needed to respond to a
release of any toxic or hazardous waste or substance into the environment.
Borrower has no material contingent liability in connection with any release of
any toxic or hazardous waste or substance into the environment.

         14. Pledge of Assets. Not mortgage, pledge, grant or permit to exist a
security interest in, or lien upon, all or any portion of Borrower's assets now

real property, inventory or equipment securing indebtedness permitted under
Section V.10(b) and (c), (b) any of the foregoing in favor of Bank, (c) liens
for taxes, assessments or other governmental charges which are not due and which
remain payable without penalty or which are being contested in good faith,
provided that adequate reserves therefor have been established, which reserves
in accordance with generally accepted accounting principles, consistently
applied, (d) liens in connection with insurance or compensation funds, pensions,

assets were acquired by Borrower or any of its subsidiaries, and (g) liens on
deposit accounts in the nature of set off rights, banker's liens or other

         15. Year 2000 Compliance. Perform all acts reasonably necessary to

Page 10


include, without limitation, performing a comprehensive review and assessment of
all of Borrower's systems and adopting a detailed plan, with itemized budget,
for the remediation, monitoring and testing of such systems. As used herein,
"Year 2000 Compliant" shall mean, in regard to any entity, that all software,
hardware, firmware, equipment, goods or systems utilized by or material to the
business operations or financial condition of such entity, will properly perform
date sensitive functions before, during and after the year 2000. Borrower shall,
immediately upon request, provide to Bank such certifications or other evidence
of Borrower's compliance with the terms hereof as Bank may from time to time
require.


VI.  DEFAULT, REMEDIES:

         1. Default, Remedies. Upon the violation of any term or condition of
any of the Loan Documents, or upon the occurrence of any default or defined
event of default under any of the Loan Documents: (a) all indebtedness of
Borrower under each of the Loan Documents, any term thereof to the contrary
notwithstanding, shall at Bank's option and without notice become immediately
due and payable without presentment, demand, protest or notice of dishonor, all
of which are expressly waived by Borrower; (b) the obligation, if any, of Bank
to extend any further credit under any of the Loan Documents shall immediately
cease and terminate; and (c) Bank shall have all rights, powers and remedies
available under each of the Loan Documents, or accorded by law, including
without limitation the right to resort to any or all security for any credit
extended by Bank to Borrower under any of the Loan Documents and to exercise any
or all of the rights of a beneficiary or secured party pursuant to the
applicable law. All rights, powers and remedies of Bank may be exercised at any
time by Bank and from time to time after the occurrence of any such breach or
default, are cumulative and not exclusive, and shall be in addition to any other
rights, powers or remedies provided by law or equity.

         2. No Waiver. No delay, failure or discontinuance of Bank in exercising
any right, power or remedy under any of the Loan Documents shall affect or
operate as a waiver of such right, power or remedy; nor shall any single or
partial exercise of any such right, power or remedy preclude, waive or otherwise
affect any other or further exercise thereof or the exercise of any other right,
power or remedy. Any waiver, permit, consent or approval of any kind by Bank of
any breach of or default under any of the Loan Documents must be in writing and
shall be effective only to the extent set forth in such writing.

         4. Entire Agreement; Amendment. This letter and the other Loan

connection with, this letter or any other of the Loan Documents to which it is
not a party.

         6. Severability of Provisions. If any provision of this letter shall be
prohibited by or invalid under applicable law, such provision shall be
ineffective only to the extent of such prohibition or invalidity without
invalidating the remainder of such provision or any remaining provisions of this
letter.

         7. Governing Law. This letter shall be governed by and construed in
accordance with the laws of the State of California.

         8.  Arbitration.

         (a) Arbitration. Upon the demand of any party, any Dispute shall be
resolved by binding arbitration (except as set forth in (e) below) in accordance
with the terms of this letter. A "Dispute" shall mean any action, dispute, claim
or controversy of any kind, whether in contract or tort, statutory or common
law, legal or equitable, now existing or hereafter arising under or in
connection with, or in any way pertaining to, any of the Loan Documents, or any
past, present or future extensions of credit and other activities, transactions
or obligations of any kind related directly or indirectly to any of the Loan
Documents, including without limitation, any of the foregoing arising in
connection with the exercise of any self-help, ancillary or other remedies
pursuant to any of the Loan Documents. Any party may by summary proceedings
bring an action in court to compel arbitration of a Dispute. Any party who fails
or refuses to submit to arbitration following a lawful demand by any other party
shall bear all costs and expenses incurred by such other party in compelling
arbitration of any Dispute.

         (b) Governing Rules. Arbitration proceedings shall be administered by
the American Arbitration Association ("AAA") or such other administrator as the
parties shall mutually agree upon 

   13

Network Appliance, Inc.
July 10, 1998
Page 13


in accordance with the AAA Commercial Arbitration Rules. All Disputes submitted
to arbitration shall be resolved in accordance with the Federal Arbitration Act
(Title 9 of the United States Code), notwithstanding any conflicting choice of
law provision in any of the Loan Documents. The arbitration shall be conducted
at a location in California selected by the AAA or other administrator. If there
is any inconsistency between the terms hereof and any such rules, the terms and
procedures set forth herein shall control. All statutes of limitation applicable
to any Dispute shall apply to any arbitration proceeding. All discovery
activities shall be expressly limited to matters directly relevant to the
Dispute being arbitrated. Judgment upon any award rendered in an arbitration may
be entered in any court having jurisdiction; provided however, that nothing
contained herein shall be deemed to be a waiver by any party that is a bank of
the protections afforded to it under 12 U.S.C. Section 91 or any similar
applicable state law.

         (c) No Waiver; Provisional Remedies, Self-Help and Foreclosure. No
provision hereof shall limit the right of any party to exercise self-help
remedies such as setoff, foreclosure against or sale of any real or personal
property collateral or security, or to obtain provisional or ancillary remedies,
including without limitation injunctive relief, sequestration, attachment,
garnishment or the appointment of a receiver, from a court of competent
jurisdiction before, after or during the pendency of any arbitration or other
proceeding. The exercise of any such remedy shall not waive the right of any
party to compel arbitration or reference hereunder.

         (d) Arbitrator Qualifications and Powers; Awards. Arbitrators must be
active members of the California State Bar or retired judges of the state or
federal judiciary of California, with expertise in the substantive law
applicable to the subject matter of the Dispute. Arbitrators are empowered to
resolve Disputes by summary rulings in response to motions filed prior to the
final arbitration hearing. Arbitrators (i) shall resolve all Disputes in
accordance with the substantive law of the state of California, (ii) may grant
any remedy or relief that a court of the state of California could order or
grant within the scope hereof and such ancillary relief as is necessary to make
effective any award, and (iii) shall have the power to award recovery of all
costs and fees, to impose sanctions and to take such other actions as they deem
necessary to the same extent a judge could pursuant to the Federal Rules of
Civil Procedure, the California Rules of Civil Procedure or other applicable
law. Any Dispute in which the amount in controversy is $5,000,000 or less shall
be decided by a single arbitrator who shall not render an award of greater than
$5,000,000 (including damages, costs, fees 


   14

Network Appliance, Inc.
July 10, 1998
Page 14

and expenses). By submission to a single arbitrator, each party expressly waives
any right or claim to recover more than $5,000,000. Any Dispute in which the
amount in controversy exceeds $5,000,000 shall be decided by majority vote of a
panel of three arbitrators; provided however, that all three arbitrators must
actively participate in all hearings and deliberations.

         (e) Judicial Review. Notwithstanding anything herein to the contrary,
in any arbitration in which the amount in controversy exceeds $25,000,000, the
arbitrators shall be required to make specific, written findings of fact and
conclusions of law. In such arbitrations (i) the arbitrators shall not have the
power to make any award which is not supported by substantial evidence or which
is based on legal error, (ii) an award shall not be binding upon the parties
unless the findings of fact are supported by substantial evidence and the
conclusions of law are not erroneous under the substantive law of the state of
California, and (iii) the parties shall have in addition to the grounds referred
to in the Federal Arbitration Act for vacating, modifying or correcting an award
the right to judicial review of (A) whether the findings of fact rendered by the
arbitrators are supported by substantial evidence, and (B) whether the
conclusions of law are erroneous under the substantive law of the state of
California. Judgment confirming an award in such a proceeding may be entered
only if a court determines the award is supported by substantial evidence and
not based on legal error under the substantive law of the state of California.

         (f) Real Property Collateral; Judicial Reference. Notwithstanding
anything herein to the contrary, no Dispute shall be submitted to arbitration if
the Dispute concerns indebtedness secured directly or indirectly, in whole or in
part, by any real property unless (i) the holder of the mortgage, lien or
security interest specifically elects in writing to proceed with the
arbitration, or (ii) all parties to the arbitration waive any rights or benefits
that might accrue to them by virtue of the single action rule statute of
California, thereby agreeing that all indebtedness and obligations of the
parties, and all mortgages, liens and security interests securing such
indebtedness and obligations, shall remain fully valid and enforceable. If any
such Dispute is not submitted to arbitration, the Dispute shall be referred to a
referee in accordance with California Code of Civil Procedure Section 638 et
seq., and this general reference agreement is intended to be specifically
enforceable in accordance with said Section 638. A referee with the
qualifications required herein for arbitrators shall be selected pursuant to the
AAA's selection procedures. 


   15

Network Appliance, Inc.
July 10, 1998
Page 15


Judgment upon the decision rendered by a referee shall be entered in the court
in which such proceeding was commenced in accordance with California Code of
Civil Procedure Sections 644 and 645.

         (g) Miscellaneous. To the maximum extent practicable, the AAA, the
arbitrators and the parties shall take all action required to conclude any
arbitration proceeding within 180 days of the filing of the Dispute with the
AAA. No arbitrator or other party to an arbitration proceeding may disclose the
existence, content or results thereof, except for disclosures of information by
a party required in the ordinary course of its business, by applicable law or
regulation, or to the extent necessary to exercise any judicial review rights
set forth herein. If more than one agreement for arbitration by or between the
parties potentially applies to a Dispute, the arbitration provision most
directly related to the Loan Documents or the subject matter of the Dispute
shall control. This arbitration provision shall survive termination, amendment
or expiration of any of the Loan Documents or any relationship between the
parties.

         Your acknowledgment of this letter shall constitute acceptance of the
foregoing terms and conditions. Bank's commitment to extend any credit to
Borrower pursuant to the terms of this letter shall terminate on August 10,
1998, unless this letter is acknowledged by Borrower and returned to Bank on or
before that date.

                                        Sincerely,

                                        WELLS FARGO BANK,
