                                     PART I

Item 1:  BUSINESS

Zitel Corporation ("Zitel" or the "Company") is an information technology
company specializing in computer and systems optimization, data correlation
and search technology. The Company's wholly-owned subsidiary, Datametrics
Systems Corporation ("Datametrics"), is an information technology company
comprised of a software products and professional services group marketing
multi-platform performance analysis and automatic correlation software used
to optimize performance in E-Business systems, storage, databases and
applications; and a group that provides software-based Internet tools to
monitor and report on performance of World Wide Web ("Web") sites,
Web-hosting services, services offered by Internet Service Providers ("ISPs")
and Application Service Providers ("ASPs"), Cyber-Merchants, as well as
Corporate Intranets (internal resources) and Extranets (links to partners and
business-to-business E-Commerce). The business operates under the
Datametrics-Registered Trademark- Systems name.

The Company was organized in 1979 to develop, market and sell semiconductor
memory systems. It subsequently developed memory algorithms which it
incorporated in high performance data storage systems developed, marketed and
sold by its data storage business. With the acquisition, in June 1997, of the
business of Datametrics Systems Corporation, the Company commenced the
transition to an information technology company. This transition was
substantially accomplished in July 1998, when the Company sold its data
storage business.

The Company's solution services business was launched during fiscal 1997
and provided Year 2000 conversion services.  The primary code conversion
methodology was based on MatriDigm Corporation's MAP2000 process.  The
Company invested in certain rights to utilize the MAP2000 process. The demand
for such Year

                                     Page 2

<PAGE>
2000 conversion services emerged more slowly than originally anticipated by
industry sources and the Company suspended its solution services business and
terminated a planned acquisition of MatriDigm in September 1999.

                                     General

Zitel develops and markets E-Business performance management solutions
through its Datametrics' business. Product offerings include: multi-platform
performance analysis and correlation software used to optimize performance in
E-Business infrastructure systems; professional services to enhance its
offerings to existing and new customers; and software-based Internet tools.

The Company markets and supports the high-end performance management suite of
ViewPoint-Registered Trademark- software utilized by E-Businesses for
infrastructure data management that automatically alerts, analyzes,
correlates, investigates, and reports on data center performance for
mainframe computers, open systems, servers, and distributed network elements.
In addition, professional services are provided to solve customers' design,
planning, and implementation needs (including customization). Training is
available to assist customers in preparing their staff for the improved
performance environment, including training on performance products and
methodologies. Products are sold through a direct sales force in the United
States and Europe, and through distributors and partners worldwide. The
Company provides both direct and indirect customer maintenance and support
for its software products.

The Company markets software-based Internet tools to monitor and report on
performance of Web sites, Web-hosting services, services offered by ISPs and
ASPs, Cyber-Merchants, as well as Corporate Intranets (internal resources) and
Extranets (links to partners and business-to-business E-Commerce). These
products and services are primarily marketed and supported via the Web.

An investment in the Company involves a high degree of risk. Please refer to
information included under the caption "Risk Factors", below.

                              Products and Services

Software Products

The Company, on June 30, 1997, concluded the acquisition of three

                                     Page 3

<PAGE>
companies primarily engaged in development and marketing of software products:
Datametrics Systems Corporation, headquartered in Fairfax, Virginia; Palmer &
Webb Systems, Limited, headquartered in the United Kingdom; and Palmer & Webb
Systems, B.V., headquartered in The Netherlands. These entities combined with
the Company's subsidiary, Performance & Modeling, Inc., to provide automated
performance analysis and correlation software to solve computer performance
problems of mainframe computers, open systems servers and distributed network
systems. Corporate customers with significant investments in management
information systems utilize these products to maximize efficiency of existing
systems and plan system enhancements. The ViewPoint product suite automatically
monitors, alerts, analyzes, and reports on potential performance problems before
they happen, hence, improving service levels, minimizing risk, and facilitating
planning for the future.

ViewPoint is a real-time data collector of approximately 2,000 different system
attributes. It operates on select computer mainframes (backend and e-commerce
systems) and all major open systems and server platforms. While the data is
collected on the computer system, ViewPoint allows the user to replay the
real-time data on any Windows-based PC. Included in ViewPoint are extensive
comparative and automatic analysis capabilities and an automatic correlation
engine.

The complementary suite of Visual products (including the VisualRoute-TM-,
VisualRoute Server, and VisualPulse-TM- products) provides Internet tools to
monitor and report on service levels and response of Web sites, Web-hosting
services, services offered by ISPs and ASPs, Cyber-Merchants, as well as
Corporate Intranets (internal resources) and Extranets (links to partners and
business-to-business E-Commerce). Included in these products are advanced
technologies, including Java and other Web-based functionality, and significant
features, both newly developed and derived from the intellectual property and
experience associated with the existing ViewPoint product, and years of
experience in the performance management arena.

                                    Marketing

The Company's software products are sold through a direct sales force in the
United States, the United Kingdom and The Netherlands, and through
distributors and partners worldwide. The Company will expand sales of certain
products and services via the Internet in the coming fiscal year. The Company
provides direct customer maintenance and support for its software products.

                                   Competition

The market for E-Business and Internet performance management tools in which the
Company's software products business competes is intensely competitive. Many of
the companies with which the Company competes such as TeamQuest Corporation,
Computer Associates International, Inc., Hewlett-Packard Company, and BMC
Software, Inc. have substantially larger installed bases and greater financial
resources than the Company. New companies will appear and may compete with
certain of the Company's products and services. The Company believes the
important considerations for software customers are ease of use, automated
functionality, product reliability, quality and price, as well as complementary
services offered. The Company believes that it competes favorably in each of
these areas.

                             Proprietary Technology

The Company currently relies on a combination of patent, copyright and trademark
laws, trade secrets, confidentiality agreements and contractual provisions to
protect its proprietary rights. The Company seeks to protect its software and
written materials, including documentation, under trade secret and copyright
laws, which afford only limited protection. The Company has registered its Zitel
and Datametrics trademarks and will continue to evaluate the registration of
additional trademarks as appropriate. The Company generally enters into
confidentiality agreements with its employees and with key vendors and
suppliers. The Company currently has one United States patent. The Company
believes that the rapidly changing technology in the computer industry makes the
Company's success depend more on the technical competence and creative skills of
its personnel than on patents.

                                    Employees

At the end of fiscal 1999, the Company employed 117 persons on a full-time
basis: 22 in research and development, 13 in professional services, 7 in
operations, 50 in sales and marketing, and 25 in general management and
administration.

The Company believes that its further success will depend, in part, on its
ability to attract and retain qualified employees, who are in great demand. None
of the Company's employees are represented by a labor union and the Company
believes that its employee relations are good.

<PAGE>
                       Investment in MatriDigm Corporation

The Company invested $7.4 million to acquire a 31% interest in MatriDigm
Corporation ("MatriDigm") from fiscal year 1996 through fiscal year 1998. The
Company recorded approximately $624 thousand in losses under the equity method
from the unconsolidated company during the year ended September 30, 1998. Zitel
also wrote off its investment in MatriDigm and fully reserved certain demand
notes and bank guarantees during fiscal 1998.

Zitel advanced MatriDigm an additional $4.9 million during fiscal year 1999. The
Company paid $250 thousand during the year ended September 30, 1999, for a
non-exclusive, royalty-bearing license for the MatriDigm technology. Zitel also
entered into an agreement to acquire the balance of MatriDigm in August 1999.
This agreement was terminated in September 1999 and MatriDigm filed Chapter 7
bankruptcy in October 1999. The Company recorded approximately $5.1 million
during fiscal year 1999 in the write-off of the license and all advances to the
company.

                                  Risk Factors

Recent Levels of Net Sales Have Been Insufficient

Zitel has not generated net sales sufficient to produce an operating profit in
recent years. The Company has relied on significant financings to support its
activities. Operations in prior years were also partially funded by a stream of
royalty payments under an agreement with IBM. This agreement was terminated in
April 1998 for a lump sum payment of $740,000. Zitel sustained substantial
operating losses and net losses in the fiscal years 1997 through 1999. Zitel
must generate substantial additional net sales and gross margins on its products
and services and must continue to successfully implement programs to manage cost
and expense levels in order to remain a viable operating entity. There is no
assurance that Zitel can achieve these objectives.

Significant Losses

The Company reported a total net loss for fiscal year 1999 of $13,103,000. The
Company reported total net losses of $43,205,00 and $17,501,000 for fiscal years
1998 and 1997, respectively.

The Company has taken a number of steps to attempt to return to profitability,
although there is no assurance that it will be

                                     Page 6
<PAGE>
successful. A significant portion of the cumulative losses were caused by the
funding of MatriDigm, and operations of the Company's former storage systems
business, which was sold in July 1998. MatriDigm filed Chapter 7 bankruptcy in
October 1999 so there will be no additional funding. The Company began
subleasing a portion of its Fremont, CA headquarters, and is considering a move
to substantially smaller and less costly premises.

The Company continues to consider options and take actions necessary to bring
costs into line with anticipated revenues. There can be no assurance that the
Company will be successful in this effort and remain a viable operating entity.

Fluctuations in Quarterly Results

Zitel'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, cancellation or rescheduling
      of significant orders;

     -Market acceptance of new products and product enhancements;

     -New product announcements or introductions by Zitel's competitors;

     -Deferrals of customer orders in anticipation of new products or product
      enhancements;

     -Changes in pricing by Zitel or its competitors;

     -The ability of Zitel to develop, introduce and market new products and
      product enhancements on a timely basis;

     -Zitel's success in expanding its sales and marketing programs;

     -Technological changes in the market for Zitel's products;

     -Product mix and the mix of sales among Zitel's sales channels;

     -Levels of expenditures on research and development;

     -Changes in Zitel's strategy; personnel changes; and,

     -General economic trends and other factors.

                                     Page 7
<PAGE>
Due to all of the foregoing factors, Zitel believes that 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. It is possible
that in some future quarter the Company's operating results may be below the
expectations of public market analysts and investors.

Zitel Stock Price Has Been Volatile

The price of Zitel's Common Stock was subject to extreme volatility during
fiscal 1998, as the closing bid price ranged between a low of 2 7/32 and a high
of 23 5/8. Zitel feels that one of the reasons for this volatility was rumored
progress of and rumored problems in the product development program and
marketing efforts of MatriDigm. The price of Zitel's Common Stock during fiscal
year 1999 demonstrated significantly less volatility, ranging from the low
closing bid price of 1 7/32 to the high closing bid price of 6 15/32.

Competition

The market for E-Business and Internet performance management tools in which
the Company's software products business competes is intensely competitive.
Many of the companies with which the Company competes, such as TeamQuest
Corporation, Computer Associates International, Inc., Hewlett-Packard
Company, and BMC Software, Inc. have substantially larger installed bases and
greater financial resources than the Company. There can be no assurance that
the Company's current competitors or new companies will not develop products
comparable or superior to those developed by the Company or adapt more
quickly than the Company to new technologies, evolving industry standards,
new product introductions, or changing customer requirements.

Dependence on New Products; Rapid Technological Change

The markets in which the Company operates are characterized by rapid
technological change, changing customer needs, frequent new product
introductions and evolving industry standards. The introduction of products
embodying new technologies and/or the emergence of new industry standards
could render the Company's existing products and services obsolete and
unmarketable. The Company's future success will depend upon its ability to
develop and to introduce new products and services 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

                                     Page 8
<PAGE>
successful in developing and marketing products or services 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 services, or that its new products
or services 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 or services in a timely manner in response
to changing market conditions or customer requirements, the Company's business,
operating results and financial condition will be materially and adversely
affected.

Product Liability

The Company's agreements with its customers typically contain provisions
intended to limit the Company's exposure to potential product liability claims.
It is possible that the limitation of liability provisions contained in the
Company's agreements may not be effective. Although the Company has not received
any product liability claims to date, the sale and support of products by the
Company and the incorporation of products from other companies may entail the
risk of such claims. A successful product liability claim against the Company
could have a material adverse effect on the Company's business, operating
results and financial condition.

Dependence on Proprietary Technology

The Company's success depends significantly upon its proprietary technology. The
Company currently relies on a combination of patent, copyright and trademark
laws, trade secrets, confidentiality agreements 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 protection. The Company has registered its Zitel and
Datametrics trademarks and will continue to evaluate the registration of
additional trademarks as appropriate. The Company generally enters into
confidentiality agreements with its employees and with key vendors and
suppliers. The Company currently holds a United States patent on one of its
software technologies. There can be no assurance that this 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. The Company believes that the rapidly
changing technology in the

                                     Page 9
<PAGE>
computer industry makes the Company's success depend more on the technical
competence and creative skills of its personnel than on patents.

There has also been substantial litigation in the computer industry regarding
intellectual property rights, and litigation may be necessary to protect the
Company's proprietary technology. The Company has not received significant
claims that it is infringing third parties' intellectual property rights, but
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 its markets will increasingly be subject
to infringement claims as the number of products and competitors in the
Company's target markets grows. Any such claims or litigation may be
time-consuming and costly, 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 on the Company's
business, operating results or financial condition. 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. 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.

International Sales and Operations

Sales to customers outside the United States have accounted for significant
portions of the Company's net sales, and the acquisition of companies
headquartered and operating in the United Kingdom and The Netherlands has
resulted in international sales representing an increasingly significant portion
of the Company's net sales. International sales pose certain risks not faced by
companies that limit themselves to domestic sales. Fluctuations in the value of
foreign currencies relative to the U.S. dollar, for example, could make the
Company's products less price competitive. If the Company, in the future,
denominates any of its sales in foreign currencies, this could result in losses
from foreign currency transactions. International sales also could be adversely
affected by factors beyond the Company's

                                     Page 10
<PAGE>
control, including the imposition of government controls, export license
requirements, restrictions on technology exports, changes in tariffs and taxes
and general economic and political conditions. The laws of some countries do not
protect the Company's intellectual property rights to the same extent as the
laws of the United States. The Company does not believe these additional risks
are significant in the United Kingdom, The Netherlands, or in the recent
acquisition of Datametrics Systems AG in Switzerland. Please refer to
information included in Notes to Consolidated Financial Statements - Subsequent
Events, below.

Dependence on Key Personnel

The Company's future performance depends significantly upon the continued
service of its key technical and senior management personnel. The Company
provides incentives such as salary, benefits and option grants (which are
typically subject to vesting over four years) to attract and retain qualified
employees. The loss of the services of one or more of the Company's officers or
other key employees could have a material adverse effect on the Company's
business, operating results and financial condition. The Company's future
success depends on its continuing ability to retain highly qualified technical
and management personnel. Competition for such personnel is intense, and there
can be no assurance that the Company can retain its key technical and management
employees or that it can attract, assimilate and retain other highly qualified
key technical and management personnel in the future.

The Company believes there is significant competition for the few software
development professionals with the advanced technological skills necessary to
perform the services offered by the Company's business. The Company's ability to
maintain or renew existing relationships and obtain new business depends, in
large part, on its ability to hire and retain technical personnel. An inability
to hire such additional qualified personnel could impair the ability of the
business to manage and complete its existing projects and to bid for and obtain
new projects.

Anti-Takeover Provisions

Certain provisions of the Company's Certificate of Incorporation, as amended and
restated, and Bylaws, as amended, California law and the Company's
indemnification agreements with certain officers and directors of the Company
may be deemed to have an anti-takeover effect. Such provisions may delay, defer
or

                                     Page 11
<PAGE>
prevent a tender offer or takeover attempt that one or more stockholders
consider to be in the best interests of same, including attempts that might
result in a premium over the market price for the shares held by stockholders.

The Company's Board of Directors may issue additional shares of Common Stock or
establish one or more classes or series of Preferred Stock, having the number of
shares, designations, relative voting rights, dividend rates, liquidation and
other rights, preferences and limitations determined by the Board of Directors
without stockholder approval.

The Board of Directors of the Company has approved the adoption of a Preferred
Share Purchase Rights Plan (the "Rights Plan"). Terms of the Rights Plan provide
for a dividend distribution of one preferred share purchase right (a "Right")
for each outstanding share of common stock, no par value per share (the "Common
Shares"), of the Company. Each Right entitles the registered holder to purchase
from the Company one one-hundredth of a share of Series A Junior Participating
Preferred Stock, no par value (the "Preferred Stock"), at an exercise price of
$69.50 per one one-hundredth of a Preferred Share (the "Purchase Price"),
subject to adjustment, and a redemption price of $.01 per Right. Each one
one-hundredth of a share of Preferred Stock has designations and the powers,
preferences and rights, and the qualifications, limitations and restrictions
which make its value approximately equal to the value of a Common Share.

The Rights are not exercisable until the earlier to occur of (i) 10 days
following a public announcement that a person, entity or group of affiliated or
associated persons (an "Acquiring Person") has acquired beneficial ownership of
15% or more of the outstanding Common Shares or (ii) 10 business days (or such
later date as may be determined by action of the Board of Directors prior to
such time as any person(s) or entity becomes an Acquiring Person) following the
commencement of, or announcement of an intention to make, a tender offer or
exchange offer the consummation of which would result in the beneficial
ownership by an Acquiring Person of 15% or more of such outstanding Common
Shares.

The Rights have certain anti-takeover effects, as they would cause substantial
dilution to a potential Acquiring Person that attempted to acquire the Company
on terms not approved by the Company's Board of Directors. The Rights should not
interfere with any merger or other business combination approved by the Board of
Directors, since the Rights may be redeemed by the

                                     Page 12
<PAGE>
Company at $.01 per Right prior to the earliest of (i) the twentieth day
following the time that an Acquiring Person has acquired beneficial ownership of
15% or more of the Common Shares (unless extended for one or more 10 day periods
by the Board of Directors), (ii) a change of control, or (iii) the final
expiration date of the rights.

Item 2:  PROPERTIES

Zitel leases its operating facilities in Fremont, CA, Fairfax, VA, Leatherhead,
United Kingdom, and Rotterdam, The Netherlands, under non-cancelable operating
leases which expire at various dates through the year 2005. Average annual rent
is approximately $1 million per year, net of sublease income of approximately
$500 thousand per year.

Item 3:  LEGAL PROCEEDINGS

On December 14, 1998, the Company commenced a suit against VLSI Technology, Inc.
in the Superior Court of the State of California in and for the County of Santa
Clara. The complaint alleges that the defendant promised to design and develop
certain application specific integrated circuits ("ASICs") critical to the
Company's planned third-generation data storage system product (CASD-III), that
VLSI failed to design or develop the promised ASICs, and that the Company was
forced to abandon the CASD-III project and dispose of its Intelligent Storage
Systems business. The suit seeks damages with respect to CASD-III development
costs and loss of profits.

On November 29, 1999, Lynx Venture Partners I, LLC filed a complaint for Breach
of Contract, Declaratory Relief and Specific Performance (the "Complaint")
against the Company in the Superior Court of the State of California in and for
the County of Alameda. The Complaint alleges that Zitel breached the Agreement
and Plan of Merger and Reorganization among Zitel, a subsidiary of Zitel and
MatriDigm Corporation by terminating that Agreement and that Lynx was damaged by
that breach. The Complaint seeks damages, attorneys' fees, declaratory relief
and 1,000,000 shares of Zitel's common stock. The Complaint was served on
December 7, 1999. Zitel believes the Complaint is without merit and intends to
defend this action vigorously.

Item 4:  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

The Company did not submit any matters to a vote of security holders during the
fourth quarter of the fiscal year ended September 30, 1999.

         CONDITION AND RESULTS OF OPERATIONS

In addition to historical information, this Annual Report contains
forward-looking statements that involve risks and uncertainties. Future trends
in revenues and operating income will be dependent on both external factors and
on the success of the various efforts described in this report. Risks and
uncertainties include, but are not limited to, product and services demand,
market acceptance, the effect of economic conditions, the impact of competitive
products and pricing, product development, capacity and supply constraints or

General

Zitel Corporation ("Zitel" or the "Company") is an information technology
company specializing in computer and systems optimization, data correlation
and search technology. The Company's wholly-owned subsidiary, Datametrics
Systems Corporation ("Datametrics"), is an information technology company
comprised of a software products and professional services group marketing
multi-platform performance analysis and automatic correlation software used
to optimize performance in E-Business systems, storage, databases and
applications; and a group that provides software-based Internet tools to
monitor and report on performance of World Wide Web ("Web") sites,
Web-hosting services, services offered by Internet Service Providers ("ISPs")
and Application Service Providers ("ASPs"), Cyber-Merchants, as well as
Corporate Intranets (internal resources) and Extranets (links to partners and
business-to-business E-Commerce).

The Company was organized in 1979 to develop, market and sell semiconductor
memory systems. It subsequently developed memory algorithms which it
incorporated in high performance data storage systems developed, marketed and
sold by its data storage business. With the acquisition, in June 1997, of the
business of Datametrics Systems Corporation, the Company commenced the
transition to an information technology company. This transition was
substantially accomplished in July 1998, when the Company sold its data storage
business.

The Company's solution services business was launched during fiscal 1997 and
provided Year 2000 conversion services. The primary code conversion methodology
was based on MatriDigm

                                     Page 17
<PAGE>
Corporation's MAP2000 process. The Company invested in certain rights to utilize
the MAP2000 process. The demand for such Year 2000 conversion services emerged
more slowly than originally anticipated by industry sources and the Company
suspended its solution services business and terminated a planned acquisition of
MatriDigm in September 1999.

Results of Operations

Fiscal 1999 Compared with Fiscal 1998

Total revenue for fiscal year 1999 was $20,890,000 compared with total revenue
of $21,700,000 in fiscal year 1998, a decrease of $810,000 or 3.7%. The decrease
in revenue represents the net impact of an increase in revenue generated by the
Company's software business during the current fiscal year, offset by the lack
of royalty and product revenue from the storage business, which was sold in July
1998. Royalty revenue in the prior year was $1,541,000 versus none for fiscal
year 1999. Revenue generated by the storage unit, prior to its sale in July
1998, was $5,698,000 for fiscal year 1998, compared to none in the current
fiscal year. Net sales for the current year were $20,890,000 versus $20,159,000
in the prior year, an increase of $731,000 or 4%. The increase in net sales is
attributable to an increase of net sales generated by the Company's subsidiary,
Datametrics, and an increase in net sales of the Company's former solution
services business, offset by the loss of revenue from the storage business. Net
sales generated by Datametrics increased 24% from $13,794,000 in fiscal year
1998 to $17,140,000 in fiscal year 1999. The Year 2000 business contributed net
sales of approximately $3,750,000 in the 1999 fiscal year compared to $667,000
in the prior fiscal year.

Gross margin, as a percent of net sales, was 56% for the current year, compared
to 40% in the year ended September 30, 1998. The increase in gross margin
percentage during the current year is attributable to the increase in sales
generated by the higher margin software business which generated a gross margin
of approximately 62% in the current and prior years.

Research and development expenses for the year ended September 30, 1999 were 14%
of net sales compared with 32% in the prior year. Actual dollars decreased
$3,397,000, attributable to the disposal of the storage business in July 1998.
It is anticipated that research and development spending will continue to
decrease slightly as a percentage of net sales due to the increase in revenue
from currently developed software products and services.

                                     Page 18
<PAGE>
Selling, general and administrative ("SG&A") expenses were $15,474,000 or 74% of
net sales in the current year versus $24,012,000 or 119% of net sales in the
prior year. Actual spending decreased $8,538,000. The decrease in spending is
attributable to the disposal of the storage business in the prior fiscal year
and the incurred or accrued costs associated with it. Management will continue
to monitor and reduce operating expenses to bring them in line with the current
business operations.

Loss on unconsolidated subsidiary of $5.1 million in fiscal year 1999 includes
the write off of a license acquired from and advances to MatriDigm during fiscal
year 1999. Fiscal year 1998 loss on unconsolidated subsidiary of $10.6 million
includes losses under the equity method, the write off of the Company's
investment in MatriDigm and fully reserving the related demand notes and bank
guarantees.

Interest expense was $1,537,000 for the year ended September 30, 1999,
substantially all of which relates to the discount on 3% convertible
subordinated debentures. Interest expense was $3,466,000 for the fiscal year
1998; $1,111,000 related solely to the discount on the 3% convertible
subordinated debentures and $2,355,000 related to the interest on both the 3%
and 5% debentures. Interest income in the current year is $397,000 versus
$598,000 in fiscal year 1998 due to lower cash and cash equivalent balances in
fiscal year 1999.

Fiscal 1998 Compared With Fiscal 1997

Total revenue for fiscal year 1998 was $21,700,000 compared with total revenue
of $17,966,000 in fiscal year 1997, an increase of $3,734,000 or 21%. The
increase in revenue is directly attributable to an increase in net sales,
partially offset by a decrease in royalty revenue. Net sales for the 1998 fiscal
year were $20,159,000 versus $12,626,000 in fiscal 1997, an increase of
$7,533,000 or 60%. The increase in net sales is directly attributable to the net
sales generated by the Company's software business, which was only included in
the last quarter of the 1997 fiscal year. In July 1998, the Company sold it
storage business, which generated revenue in fiscal 1998 of $5,698,000 compared
with $10,304,000 in fiscal 1997. Royalty revenue for the year ending September
30, 1998 was $1,541,000 versus $5,340,000 in the prior year. The Company
negotiated and received the final payment for all royalty obligations from
International Business Machines Corporation ("IBM") in April 1998.

Gross margin, as a percent of net sales, was 40% for the year

                                     Page 19
<PAGE>
ended September 30, 1998 compared to 26% in the prior year. The increase in
gross margin percentage during fiscal year 1998 is primarily attributable to the
increase in sales generated by the software business, which generated a gross
margin of 61% for the 1998 fiscal year.

Research and development expenses for the year ended September 30, 1998 were 32%
of net sales compared with 59% in fiscal year 1997. Actual dollars decreased
$1,085,000.

Selling, general and administrative ("SG&A") expenses were $24,012,000, or 119%
of net sales, in the year ending 1998, versus $14,468,000 or 115% of net sales
in the prior year. Actual spending increased $9,544,000. The increase in
spending is primarily attributable to the added SG&A expenses of the acquired
software companies of approximately $7,250,000 and to severance costs of
$1,110,000 for the storage business personnel. Other additional SG&A costs
included a $861,000 increase in spending of the solution services business, an
increase of $655,000 in legal costs, and a $750,000 estimated loss on excess
capacity at the Fremont, CA facility.

Because of the uncertainties in MatriDigm Corporation's future and their ability
to generate sufficient operating cash flows, the Company wrote off its
investment of $7,414,000 and reserved $3,202,000 for a total loss of
$10,616,000. The reserve of $3,202,000 is comprised of $2,022,000 against demand
notes, a bank guarantee of $1,000,000, and a note and an option from an officer
of MatriDigm in the amount of $180,000.

Interest expense was $3,466,000 for the fiscal year 1998; $1,111,000 related
solely to the discount on the 3% convertible subordinated debentures and
$2,355,000 related to the interest on both the 3% and 5% debentures. Interest
expense in 1997 was $3,532,000 of which $2,778,000 related to a discount on 5%
convertible subordinated debentures issued during that fiscal year. Interest
income in fiscal year 1998 was $598,000 compared to $746,000 in the prior year.

Due to the uncertainty surrounding the realization of the net operating losses
and credit carryforwards in future tax years, the Company established a 100%
valuation allowance against its deferred tax asset in the amount of $6,500,000
during fiscal year 1998.


                                    Page 20

Liquidity and Capital Resources

The Company's principal sources of working capital are product sales and
convertible debt. During the fiscal year ended September 30, 1999, working
capital decreased to $1,057,000 and cash flow utilized by operating activities
was $6,653,000. The utilization of cash in operating activities resulted
primarily from the net loss of $13,103,000, a decrease in accounts payable of
$1,017,000 and an increase in accounts receivable of $422,000. This was
partially offset by amortization of capitalized financing costs of $479,000,
amortization of discount on subordinated debenture of $555,000, an increase in
the provision for doubtful accounts of $282,000, depreciation and amortization
in the amount of $2,511,000, and loss from unconsolidated company of $5,098,000.

During the current year, net cash utilized in investing activities was
$5,764,000. This amount was comprised of the Company's investment in and
advances to unconsolidated company of $5,098,000 and the purchase of fixed
assets and increase in other assets in the amount of $666,000.

Net cash provided by financing activities was $7,498,000 which included
$5,342,000 raised from the issuance of 3% convertible subordinated debentures,
$2,000,000 received from the issuance of Series B preferred stock, and $156,000
from the exercise of employee stock options and for the sale of stock under the
Company's employee stock purchase plan.

Management believes that the Company will meet its cash requirements for the
next twelve months from cash on hand, working capital, and cash flow from
operations. If the Company is unable to generate sufficient cash flow from
operations or should management determine it to be prudent, it may attempt to
raise additional debt or equity. There can be no assurance that management will
be able to raise additional debt or equity financing.

Zitel negotiated a credit facility of a $2 million accounts receivable factoring
agreement, on October 15, 1999. Please refer to information included in Notes to
Consolidated Financial Statements - Subsequent Events, below.

Recent Accounting Pronouncements

In June 1998, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards ("SFAS") No.

                                     Page 21
<PAGE>
133, "Accounting for Derivative Instruments and Hedging Activities". SFAS No.
133 establishes accounting and reporting standards requiring that every
derivative instrument, including certain derivative instruments embedded in
other contracts, be recorded in the balance sheet as either an asset or
liability measured at its fair value. SFAS No. 133 requires that changes in the
derivative's fair value be recognized currently in earnings unless specific
hedge accounting criteria are met. Special accounting for qualifying hedges
allows a derivative's gains and losses to offset related results on the hedged
item in the income statement, and requires that a company must formally
document, designate and assess the effectiveness of transactions that receive
hedge accounting. SFAS No. 133 is effective for the Company in fiscal year 2000
and will not require retroactive restatement of prior period financial
statements. The Company has not yet quantified the impact of adopting SFAS No.
133 on its financial statements, but the Company believes there will not be a
significant impact.

In December 1998, Accounting Standards Executive Committee ("AcSEC") released
Statement of Position 98-9 ("SOP 98-9"), "Modification of Statement of Position
97-2 (SOP 97-2), `Software Revenue Recognition', with Respect to Certain
Transactions". SOP 98-9 amends SOP 97-2 to define how an entity recognizes
revenue for multiple element arrangements for each element delivered. The
provisions of SOP 98-9 became effective December 15, 1998. These paragraphs of
SOP 97-2 and SOP 98-9 will be effective for transactions that are entered into
in fiscal years beginning after March 15, 1999. Retroactive application is
prohibited. We do not expect the adoption of SOP 98-9 to have a material effect
on our current revenue recognition policies.

Impact of the Year 2000 Issue

The costs of the planned Year 2000 modifications and the dates by which the
Company expects to complete its plans are based on Management's best estimates,
which were derived utilizing numerous assumptions of future events, including
the continued availability of certain resources, third-party modification plans
and other factors. Specific factors that might cause differences between the
estimates and actual results include, but are not limited to, the availability
and cost of personnel trained in these areas, the ability to locate and correct
all relevant computer codes, changes in consulting fees and costs to remediate
or replace hardware and software as well as non-incremental costs resulting from
redeployment of internal resources, timely


                                     Page 22
<PAGE>
responses to and corrections by third parties such as significant customers and
suppliers, and similar uncertainties.

The Year 2000 issue is the result of computer programs being written using two
digits rather than four to define the applicable year. The issue arises if
date-sensitive software recognizes a date using "00" as the year 1900 rather
than the year 2000. This could result in a system failure or miscalculations
causing disruptions of operations, including, among other things, a temporary
inability to process transactions, send invoices, or engage in similar normal
business activities.

The Company's information technology systems consist primarily of hardware and
software purchased from outside parties. The vendor for the Company's
enterprise-wide software has informed the Company that the version of its
software that the Company is currently utilizing is Year 2000 compliant. The
Company utilized a seven step process in addressing compliance of other
non-enterprise hardware and software systems: (1) awareness; (2) inventory of
all systems and documentation; (3) assessment to identify any areas of
noncompliance; (4) remediation/renovation of any noncompliant systems; (5)
verification of compliance through testing and/or vendor certification; (6)
implementation of any necessary changes revealed during verifications; and (7)
monitoring of the results of implementation. The Company has completed the
entire process for its non-enterprise software and hardware as of November 30,
1999.

The Company has identified and made inquiries of its significant suppliers and
large public and private sector customers to determine the extent to which the
Company is vulnerable to those third parties' failure to solve their own Year
2000 issues. There can be no guarantee that the systems of other companies or
public agencies with which the Company does business will be timely converted,
or that failure to convert by another company or public agency would not have a
material adverse effect on the Company.

The Company's most likely worst-case Year 2000 scenario would be an interruption
in work or cash flow resulting from unanticipated problems encountered with the
information systems of the Company, or of any of the significant third parties
with whom the Company does business. The Company believes that the risk of
significant business interruption due to unanticipated problems with its own
systems is low based on the completion of the Year 2000 project. If unforeseen
internal disruptions occur, the Company believes

                                     Page 23
<PAGE>
that its existing disaster recovery program, which includes the manual
processing of certain key transactions, would significantly mitigate the impact.
The Company's highest risk relates to significant suppliers or customers failing
to remediate their Year 2000 issues in a timely manner. Relating to its
suppliers, the Company has identified and will continue to identify alternative
suppliers. The Company's suppliers are generally locally or regionally based,
which tends to lessen the Company's exposure from the lack of readiness of any
single supplier. The risk relating to the Company's customers relates primarily
to any delay in receipt of payment due to a customer's unresolved Year 2000
issue. The Company's existing financial resources will help to mitigate such an
impact and the Company will continue to assess this risk as it receives
communications about the Year 2000 status of its customers.

The Company estimates that costs to address the Year 2000 issue will be
insignificant, including costs already incurred. Estimates consider consulting
fees and costs to remediate or replace hardware and software as well as
non-incremental costs resulting from redeployment of internal resources. The
Company's Year 2000 costs will be funded from its operating cash flows.

Item 7A: Quantitative and Qualitative Disclosures about Market Risk

The Company considered the provision of Financial Reporting Release No. 48,
"Disclosure of Accounting Policies for Derivative Financial Instruments and
Derivative Commodity Instruments, and Disclosure of Quantitative and Qualitative
Information about Market Risk Inherent in Derivative Financial Instruments,
Other Financial Instruments and Derivative Commodity Instruments". The Company
had no holdings of derivative financial or commodity instruments at September
30, 1999. A review of other financial instruments and risk exposures at that
date revealed the Company did not have exposure to interest rate risk.

Notes to Consolidated Financial Statements
(In thousands except per share data)

Summary of Significant Accounting Policies:

Zitel Corporation ("Zitel" or the "Company") is an information technology
company specializing in computer and systems optimization, data correlation and
search technology. Zitel acquires, develops and markets E-Business performance
management solutions. Product offerings include multi-platform performance
analysis and automatic correlation software used to optimize performance in
E-Business infrastructure systems, professional services for existing and new
customers, and software-based Internet tools.

The following is a summary of Zitel's significant accounting policies:

Basis of Presentation:

These consolidated financial statements contemplate the realization of assets
and the satisfaction of liabilities in the normal course of business. The
Company has incurred losses in each of the last three fiscal years and has an
accumulated deficit. Fiscal year 1998 included losses from the storage business,
which was sold in July 1998 and the write off of the Company's investment in
MatriDigm Corporation ("MatriDigm"). Fiscal year 1999 losses included amounts
advanced to MatriDigm during 1999. MatriDigm filed Chapter 7 bankruptcy in
October 1999 and no further advances will be made.

Management's plans to reverse the recent trend of losses are to increase
revenues and gross margins while controlling costs. If the Company is unable to
generate adequate cash flows from operations, the Company may need to seek
additional sources of capital. There can be no assurance that the Company will
be able to obtain such funding, if necessary, on acceptable terms or at all.

Principles of Consolidation:

The consolidated financial statements include the accounts of Zitel Corporation
and its wholly-owned subsidiaries. All significant intercompany accounts and
transactions have been eliminated.

<PAGE>
Use of Estimates:

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amount 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.
Actual results could differ from these estimates.

Cash Equivalents:

For purposes of the statements of cash flows, the Company considers all highly
liquid debt instruments purchased with a maturity of three months or less to be
cash equivalents.

Fixed Assets:

Fixed assets are stated at cost less accumulated depreciation, other than
leasehold improvements, and are depreciated on a straight-line basis over their
estimated useful lives (three years). Leasehold improvements are amortized over
the lesser of their useful life or remaining term of the related lease. When
assets are disposed of, the cost and related accumulated depreciation are
removed from the accounts and the resulting gains and losses are included in the
results of operations.

Deferred Software Implementation Costs:

The Company capitalizes substantially all costs related to the purchase of
software and its implementation, which includes the cost of purchased software,
consulting fees and the use of certain specified Company resources. Zitel
amortizes such costs on a straight-line basis over the estimated life of the
computer software, which is five years. The Company evaluates the fair value of
the deferred software implementation costs at each balance sheet date and
records write-downs to the recoverable costs. In June 1998, the Company wrote
down the net book value of amounts capitalized, which related to all the
manufacturing modules of the recently sold storage business. No such write-downs
were deemed necessary in fiscal year 1999. As of September 30, 1999 and 1998,
$351 thousand in costs have been capitalized and are included in other long-term
assets. Amortization in the amount of $94 thousand and $193 thousand was charged
to expense during fiscal years 1999 and 1998, respectively. American Institute
of Certified Public Accountants SOP 98-1, "Accounting for Costs of Computer
Software Developed or Obtained for Internal

                                    Page 30
<PAGE>
Use", issued on March 4,1998, became effective for the Company in fiscal year
1999. The Company believes there was no impact on the Financial Statements.

Revenue Recognition:

The Company adopted the provisions of Statement of Position 97-2 ("SOP 97-2"),
"Software Revenue Recognition", as amended by SOP 98-4, "Deferral of the
Effective Date of Certain Provisions of SOP 97-2", effective October 1, 1998.
SOP 97-2 delineates the accounting for software products, products including
software that is not incidental to the product, and maintenance revenues. Under
SOP 97-2, the Company recognizes product license revenue upon shipment if a
signed contract exists, the fee is fixed and determinable, collection of the
resulting receivables is probable and the product returns can be reasonably
estimated.

For contracts with multiple obligations (e.g., maintenance and consulting
services), revenue from product licenses are recognized when delivery has
occurred, collection of the resulting receivables is probable, the fee is fixed
and determinable and the vendor-specific objective evidence exists to allocate
the total fee to all delivered and undelivered elements of the arrangement. The
Company recognizes revenue allocated to maintenance and support fees, for
ongoing customer support and product updates, ratably over the period of the
relevant contract. For revenue allocated to consulting services and for
consulting services sold separately, the Company recognizes revenue as the
related services are performed. Maintenance and consulting services are included
in services and other revenue.

Prior to the adoption of SOP 97-2, effective October 1, 1998, the Company
recognized revenue from the sale of product licenses upon shipment if remaining
obligations were insignificant and collection of the resulting receivables was
probable. Revenue from software maintenance contracts, including amounts
unbundled from product sales, were deferred and recognized ratably over the
period of the contract.

The Company recognizes revenue from Year 2000 conversion services when the
conversion services are completed. Revenue from Year 2000 conversion services
are included in services and other revenue.

Revenue from the storage business was recognized at the time products were
shipped to customers.


                                     Page 31
<PAGE>
Warranty:

All of the Company's storage products were covered by a one-year limited
warranty. Estimated future costs of repair, replacement or customer
accommodation were accrued and charged to cost of sales based upon estimates of
future product returns and repair costs derived from historical product sales
information and analyses of historical data. In estimating the level of accrual,
the Company's management makes assumptions relating to the level of product
returns and costs of repair. Management reviews the adequacy of these
assumptions based on historical experience.

Research and Development Expenditures:

Research and development expenditures are charged to operations as incurred.

Software Development Costs:

SFAS No. 86 provides for the capitalization of certain software development
costs after technological feasibility of the software is attained. Capitalized
costs are amortized using the greater of the amount computed using the ratio
that current gross revenues for a product bear to the total of current and
anticipated gross revenues for that product, or on a straight-line basis over
the estimated product life cycle (approximately three years). The Company
evaluates the estimated net realizable value of each software product at each
balance sheet date and records write-downs to net realizable value for any
products with a net book value in excess of net realizable value. Software
development costs capitalized in fiscal years 1999 and 1998 were $381 thousand
and $562 thousand, respectively. Amortization of $410 thousand was charged to
expense for the fiscal year 1999. Amortization expense was $62 thousand and zero
for fiscal years 1998 and 1997, respectively.

Foreign Currency Translation:

The U.S. dollar is considered to be the functional currency for the Company's
foreign operations. Accordingly, non-monetary assets and liabilities have been
translated into U.S. dollars at a historical rate; monetary assets and
liabilities have been translated into U.S. dollars using the exchange rate at
the balance sheet date; and revenues and expenses have been generally translated
into U.S. dollars at the weighted average exchange rate during the period.
Foreign currency transaction gains and losses, as well as the effects of
remeasurement (which have not

                                     Page 32
<PAGE>
been material in the aggregate), are included in the accompanying statements of
operations.

Intangible Assets:

Intangible assets include goodwill and purchased technology, recorded in
connection with the acquisition of the three software companies, which are being
amortized on a straight-line basis over six and five years, respectively. The
Company periodically assesses the recoverability of intangible assets by
determining whether the amortization of the asset balance over its remaining
life can be recovered through undiscounted future operating cash flows of the
acquired operation. The amount of impairment, if any, is measured based on
projected discounted future operating cash flows and is recognized as a write
down of the asset. In fiscal year 1998, the Company reassessed the amortization
period for goodwill and reduced the life from seven to six years based on future
projections.

Income Taxes:

Deferred income taxes are recognized for temporary differences by applying
enacted statutory rates applicable to future years to differences between the
financial statement carrying amounts and the tax basis of existing assets and
liabilities. The effect on deferred taxes of a change in tax rates is recognized
in income in the period that includes the enactment date. Valuation allowances
are established when necessary to reduce deferred tax assets to the amounts
expected to be realized.

Comprehensive Loss:

Effective October 1, 1998, the Company adopted the provisions of SFAS No. 130,
"Reporting Comprehensive Income". There were no differences between
comprehensive loss and net loss as reported for each of the fiscal years 1997,
1998 and 1999.

Recent Accounting Pronouncements:

In June 1998, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards ("SFAS") No. 133, "Accounting for Derivative
Instruments and Hedging Activities". SFAS No. 133 establishes accounting and
reporting standards requiring that every derivative instrument, including
certain derivative instruments embedded in other contracts, be recorded in the
balance sheet as either an asset or liability measured at its fair value. SFAS
No. 133 requires that changes

                                     Page 33
<PAGE>
in the derivative's fair value be recognized currently in earnings unless
specific hedge accounting criteria are met. Special accounting for qualifying
hedges allows a derivative's gains and losses to offset related results on the
hedged item in the income statement, and requires that a company must formally
document, designate and assess the effectiveness of transactions that receive
hedge accounting. SFAS No. 133 is effective for the Company in fiscal year 2000
and will not require retroactive restatement of prior period financial
statements. The Company has not yet quantified the impact of adopting SFAS No.
133 on its financial statements, but the Company believes there will not be a
significant impact.

In December 1998, Accounting Standards Executive Committee ("AcSEC") released
Statement of Position 98-9 ("SOP 98-9"), "Modification of Statement of Position
97-2 (SOP 97-2), `Software Revenue Recognition', with Respect to Certain
Transactions". SOP 98-9 amends SOP 97-2 to define how an entity recognizes
revenue for multiple element arrangements for each element delivered. The
provisions of SOP 98-9 became effective December 15, 1998. These paragraphs of
SOP 97-2 and SOP 98-9 will be effective for transactions that are entered into
in fiscal years beginning after March 15, 1999. Retroactive application is
prohibited. We do not expect the adoption of SOP 98-9 to have a material effect
on our current revenue recognition policies.

Net Loss Per Share:

SFAS No. 128, "Earnings per Share", requires the presentation of basic and
diluted loss per common share. Basic loss per common share is computed by
dividing net loss by the weighted average number of common shares outstanding
for the period. Diluted loss per common share is computed giving effect to all
potentially dilutive common shares that were outstanding during the period.
Dilutive common shares consist of the incremental common shares issuable upon
the conversion of convertible subordinated debt (using the "if converted"
method) and exercise of stock options and warrants for all periods.

Concentrations of Credit Risk:

Financial instruments which potentially subject the Company to concentrations of
credit risk consist principally of cash and trade receivables. The Company
places its cash investments with high credit quality financial institutions and
limits the amount of exposure to any one financial institution. Concentrations
of credit risk with respect to accounts receivables are limited due

                                     Page 34
<PAGE>
to the diversity of the Company's customers, both geographically and within
different industry segments. The Company performs ongoing evaluations of its
customers' financial condition and generally does not require collateral. The
Company maintains allowances for potential credit losses.

Fair Value of Financial Instruments:

Carrying value amounts of certain of the Company's financial instruments,
including cash and cash equivalents, accounts receivable, accounts payable,
subordinated debentures, and other accrued liabilities approximate fair value
due to their short maturities.

Sale of Storage Business:

Due to the lack of performance of the storage business, on July 24, 1998, the
Company completed the sale of the net assets of the business, which totalled
$2.1 million, for cash and a note totalling $1.0 million and royalties of up to
$4.0 million, payable over four years based on the sales performance of the new
company. Fixed assets in the amount of $1.3 million and deferred software
implementation costs of $800 thousand, which related to manufacturing modules
that would no longer be used, were taken as a loss on impairment of assets
during fiscal year 1998. Inventory in the amount of $1.7 million and patents in
the amount of $400 thousand were charged against cost of sales during fiscal
year 1998.

Business Combinations:

On June 30, 1997, the Company acquired Datametrics Systems Corporation, Palmer &
Webb Systems Limited, and Palmer & Webb Systems B.V. The purchase price
consisted of a cash payment of $11.1 million, the issuance of shares of the
Company's common stock valued at $1.2 million and transaction costs of
approximately $500 thousand. The acquisition has been accounted for under the
purchase method of accounting. Accordingly, the total purchase price of $12.8
million was allocated to the net assets acquired based upon their estimated fair
values. In addition, $6.6 million of the purchase price was allocated to
purchased in-process research and development that has not reached technological
feasibility and that has no alternative future use. The operating results of the
acquired companies from July 1, 1997 through September 30, 1997, are included in
the consolidated results of operations.

The following table is a summary of the unaudited pro-forma financial
information with respect to the combined companies as described above,
disclosing pro-forma results of operations for the fiscal year 1997, as though
the entities had been combined as of October 1, 1997. The pro-forma results do
not reflect any non-recurring charges which resulted directly from the
transaction, such as the $6.6 million write-off of purchased research and
development.

Intangible Assets:

Intangible assets include goodwill and purchased technology, recorded in
connection with the acquisition of the three software companies, which are being
amortized on a straight-line basis over six and five years, respectively. The
Company periodically assesses the recoverability of the intangible assets by
determining whether the amortization of the asset balance over its remaining
life can be recovered through undiscounted future

                                     Page 36
<PAGE>
operating cash flows of the acquired operation. The amount of impairment, if
any, is measured based on projected discounted future operating cash flows and
is recognized as a write down of the asset. At June 30, 1998, a write-down of a
combined total of $658 thousand was made to goodwill and purchased technology.
In addition, the amortization period of goodwill was adjusted to six years from
seven years. Intangible assets consist of the following as of:

which provides for automatic, non-discretionary

                                     Page 41
<PAGE>
grants of options to purchase an aggregate of 200 thousand shares of common

Preferred Share Purchase Rights Plan:

In June 1996, the Company adopted a Preferred Share Purchase Rights Plan whereby
shareholders will receive one right to purchase one one-hundredth of a share of
a new series of preferred stock ("Rights") for each outstanding share of the
Company's common stock held at the date of record, July 1, 1996. The Rights do
not become exercisable or transferable apart from the common stock until a
person or group (a) acquires beneficial ownership of 15% or more of the
Company's common stock or (b) announces a tender or exchange offer, the
consummation of which would result in ownership by a person or group of 15% or
more of the Company's common stock. The Rights will be distributed as a
non-taxable dividend and will expire in ten years from the date of declaration
of the dividend. The exercise price is $69.50 per 1/100 of a share of preferred
stock.

Stock Purchase Plan:

In April 1984, the Board of Directors approved the adoption of an Employee Stock
Purchase Plan under which 400 thousand shares of common stock were reserved for
issuance to eligible employees.

In January 1988, January 1990, January 1992, and January 1995, the shareholders
approved amendments to increase the shares reserved for the Plan by 300 thousand
shares, 400 thousand shares, 400 thousand shares, and 500 thousand shares,
respectively. Employees who do not own 5% or more of the outstanding shares are
eligible to participate through payroll deductions, which may not exceed 10% of
an employee's

                                     Page 42
<PAGE>
compensation. At the end of each offering period, shares are purchased by the
participants at 85% of the lower of the fair market value at the beginning or
the end of the offering period. The 15% discount is treated as equivalent to the
cost of issuing stock for financial reporting purposes. During fiscal years
1999, 1998 and 1997, shares issued under the Plan were 60 thousand, 65 thousand
and 35 thousand shares, respectively. Since inception of the Plan, approximately
1.8 million shares have been issued.

Pro Forma Stock-Based Compensation:

As of September 30, 1999, options outstanding under both the stock option plans
and 1995 Non-Employees Directors' Stock Option Plan were as follows:

At September 30, 1999, the Company has federal and state net operating loss
("NOL") carryforwards of 45.6 million and 10.3 million, respectively, to reduce
future taxable income. The Company has federal and state general business credit
carryforwards of $2.5 million and $1.1 million, respectively, to reduce future
taxable income. These carryforwards expire in 2000 through 2020 if not utilized.

In addition, the Company has $6.3 million of NOLs related to stock option
exercises, the benefit of which will be credited to equity when utilized.

Due to the net loss incurred in fiscal year 1999, accumulated deficit and lack
of alternative tax planning strategies, there is uncertainty surrounding the
realization of the favorable tax attributes in future tax returns. Accordingly,
the Company placed a valuation allowance against its otherwise recognizable net
deferred tax assets.

Research and Development Contract:

During fiscal year 1992, the Company entered into a joint development contract
to develop a product with a third party. The Company received funding from the
third party based on completion milestones. In addition, upon completion of the
project, the Company has received a royalty based on sales by the third party of
the product developed. Royalties totalling approximately $1.5 million and $5.3
million were received from the third party in fiscal years 1998 and 1997,
respectively. During fiscal year 1998, the Company negotiated and received the
final payment for all royalty obligations from the third party.

Segment Information:

During fiscal year 1999, the Company had two reportable segments - Datametrics
and Year 2000 Services. The Datametrics business segment develops and markets
E-business performance management software solutions. The Year 2000 business
segment provides services which review software code and identify areas within
the code where year 2000 problems may occur.

During fiscal years 1998 and 1997, the Company also had the data storage
business segment. The data storage segment was disposed of in July 1998. The
data storage segment developed memory algorithms which it incorporated and sold
in high performance data storage systems.

Sales to one customer approximated 10.6% of net sales in 1999. There were no
sales to one customer that exceeded 10% of net sales in 1998. Sales to one
customer amounted to 14.6% of net sales in 1997.

Subsequent Events:

Credit Facility:

Zitel negotiated a $2 million accounts receivable factoring agreement, on
October 15, 1999. Borrowings are based on 80% of certain eligible receivables
which are aged 90 days or less. The commitment fee is 1% of the credit facility.
The administration fee is 1/2 of one percent of each amount factored. The
interest rate approximates 18% per annum calculated on the average daily balance
outstanding, if any.

Acquisition of Telemetrics Systems Corporation:

On October 19, 1999, Zitel Corporation purchased all outstanding shares of
Telemetrics Systems Corporation, a company domiciled in Berne, Switzerland, for
approximately $1.2 million. The transaction was accounted for as a purchase. The
wholly-owned subsidiary of the Company is now named Datametrics Systems AG.

Litigation:

On November 29, 1999, Lynx Venture Partners I, LLC filed a Complaint for Breach
of Contract, Declaratory Relief and Specific


                                     Page 50
<PAGE>
Performance against the Company in the Superior Court of the State of
California in and for the County of Alameda. The Complaint alleges that Zitel
breached the Agreement and Plan of Merger and Reorganization among Zitel, a
subsidiary of Zitel and MatriDigm Corporation by terminating that Agreement
and that Lynx was damaged by that breach. The Complaint seeks damages,
attorneys' fees, declaratory relief and 1,000,000 shares of Zitel's common
stock. The Complaint was served on December 7, 1999. While Zitel believes the
Complaint is without merit and intends to defend this action vigorously,
there can be no assurance the Lynx Complaint will be resolved without costly
litigation, or in a manner that is not adverse to the Company's financial
position, results of operations or cash flows. No estimate can be made of the
possible loss or range of loss associated with the resolution of this matter.

                        Report of Independent Accountants



To the Board of Directors and Shareholders
Zitel Corporation

In our opinion, the consolidated financial statements listed in the index
appearing under Item 14(a)(1) on page 54 present fairly, in all material
respects, the financial position of Zitel Corporation and subsidiaries at
September 30, 1999 and 1998, and the results of their operations and their
cash flows for each of the three years in the period ended September 30,
1999, in conformity with generally accepted accounting principles. In
addition, in our opinion, the financial statement schedule listed in the
index appearing under Item 14(a)(2) on page 54 presents fairly, in all
material respects, the information set forth therein when read in conjunction
with the related consolidated financial statements. These financial
statements and financial statement schedule are the responsibility of the
Company's management; our responsibility is to express an opinion on these
financial statements and financial statement schedule based on our audits. We
conducted our audits of these statements in accordance with generally
accepted auditing standards which 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,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

Insofar as indemnification for liabilities arising under the Securities Act of
1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
of 1933 and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.
