                                        1.
<PAGE>

                                   THE COMPANY

     Zitel Corporation was incorporated in California in 1979. Our executive
offices are located at 47211 Bayside Parkway, Fremont, California 94538-6517,
and our telephone number is (510) 440-9600.

                                 USE OF PROCEEDS

     We will not receive any of the proceeds from the sale of shares by the
Selling Securityholders.

                                 DIVIDEND POLICY

     Zitel has never paid cash dividends. The Company's Board of Directors
currently intends to retain any earnings for use in Zitel's business and does
not anticipate paying any cash dividends in the foreseeable future.

     AN INVESTMENT IN ZITEL INVOLVES A HIGH DEGREE OF RISK. THE RISK FACTORS SET
FORTH BELOW SHOULD BE CONSIDERED CAREFULLY BEFORE PURCHASING THE COMMON STOCK
OFFERED HEREBY.

                                  RISK FACTORS

RECENT LEVELS OF NET SALES HAVE BEEN INSUFFICIENT TO PRODUCE OPERATING PROFITS

     In recent years, we have not generated net sales sufficient to produce an
operating profit and have relied on a stream of royalty payments under an
agreement with IBM and significant financings to support our activities. In
April 1998, Zitel and IBM entered into an agreement whereby IBM stopped paying
royalties to Zitel in exchange for a lump sum payment amounting to $740,000. We
sustained substantial operating losses and net losses in fiscal 1997, fiscal
1998 and fiscal 1999. We must generate substantial additional net sales and
gross margins on our 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 can be no assurance that we can achieve these
objectives.

WE HAVE REPORTED SIGNIFICANT LOSSES

     During our 1999 fiscal year, we reported a net loss of $13,103,000. We
reported a net loss of $43,205,000 in fiscal 1998. We reported a net loss of
$17,501,000 in fiscal 1997.

     While we have taken a number of steps to attempt to return to
profitability, there is no assurance that we will be successful. A significant
portion of the recent losses were caused by the operations of our former storage
systems business unit and the writeoff of our investment in and advances to
MatriDigm Corporation. In July 1998, we sold the storage systems business unit.
At September 30, 1999, we had written off all of our investments in and advances
to MatriDigm Corporation. We are in the process of attempting to sublease our
Fremont, California headquarters and move to substantially smaller and less
costly premises. We are also taking other actions to reduce our costs in an
effort to bring costs into line with anticipated revenues. There can be no
assurance that we will be successful in this effort and remain a viable
operating entity.

WE HAVE EXPERIENCED FLUCTUATIONS IN QUARTERLY RESULTS

     Our 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, size, timing, cancellation or rescheduling
          of significant orders;

     -    Market acceptance of new products and product enhancements;

     -    New product announcements or introductions by our competitors;

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


                                      2.
<PAGE>

     -    Changes in pricing by us or our competitors;

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

     -    Our success in expanding our sales and marketing programs;

     -    Technological changes in the market for our products;

     -    Product mix and the mix of sales among our sales channels;

     -    Levels of expenditures on research and development;

     -    Changes in our strategy and personnel changes;

     -    General economic trends and other factors.

     Due to all of the foregoing factors, we believe that period-to-period
comparisons of our 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 our operating results may be below the expectations
of public market analysts and investors.

OUR STOCK PRICE HAS BEEN VOLATILE

     The price of our 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. We 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 our 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.

THE MARKET FOR SYSTEMS MANAGEMENT TOOLS IS INTENSELY COMPETITIVE

     The market for system management tools in which our software products
business unit competes is intensely competitive. Many of the companies with
which we compete, such as TeamQuest Corporation, Computer Associates
International, Inc., Hewlett-Packard Company and BMC Software, Inc., have sold
systems to many more customers and have greater financial resources than Zitel.
There can be no assurance that our competitors will not develop products
comparable or superior to those developed by us or adapt more quickly than we do
to new technologies, evolving industry standards, new product introductions, or
changing customer requirements.

RAPID TECHNOLOGICAL CHANGE COULD RENDER OUR EXISTING PRODUCTS AND SERVICES
OBSOLETE

     The markets in which we operate 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 our existing
products and services obsolete and unmarketable. Our future success will depend
upon our ability to develop and 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 our customers.
There can be no assurance that we will be successful in developing and marketing
products or services that respond to technological changes or evolving industry
standards, that we will not experience difficulties that could delay or prevent
the successful development, introduction and marketing of new products or
services, or that our new products or services will adequately meet the
requirements of the marketplace and achieve market acceptance. If we are 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, our business, operating results and financial condition
will be harmed.

PRODUCT LIABILITY COULD HURT US IF LIABILITY LIMITATIONS ARE NOT EFFECTIVE

     Our agreements with our customers typically contain provisions intended to
limit our exposure to potential product liability claims. It is possible that
the limitation of liability provisions contained in our agreements may not be
effective. Although we have not


                                      3.
<PAGE>

received any product liability claims to date, the sale and support of
products and the incorporation of products from other companies may entail
the risk of such claims. A successful product liability claim against us
could harm our business.

OUR SUCCESS DEPENDS ON PROPRIETARY TECHNOLOGY

     Our success depends significantly upon our proprietary technology. We
currently rely on a combination of patent, copyright and trademark laws, trade
secrets, confidentiality agreements and contractual provisions to protect our
proprietary rights. We seek to protect our software, documentation and other
written materials under trade secret and copyright laws, which afford only
limited protection. We have registered our Zitel and Datametrics trademarks and
will continue to evaluate the registration of additional trademarks as
appropriate. We generally enter into confidentiality agreements with our
employees and with key vendors and suppliers. We currently hold a United States
patent on one of our software technologies. There can be no assurance that this
patent will provide us with any competitive advantages or will not be challenged
by third parties, or that the patents of others will not impair our ability to
do business. We believe that the rapidly changing technology in the computer
industry makes our success depend more on the technical competence and creative
skills of our 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 our proprietary technology. We have not received significant claims that
we are infringing third parties' intellectual property rights, but there can be
no assurance that third parties will not in the future claim infringement by us
with respect to current or future products, trademarks or other proprietary
rights.

     We expect that companies in our markets will increasingly be subject to
infringement claims as the number of products and competitors in our target
markets grows. Any such claims or litigation may be time-consuming and costly,
cause product shipment delays, require us to redesign our products or require us
to enter into royalty or licensing agreements, any of which could have a harm on
our business. Despite our efforts to protect its proprietary rights,
unauthorized parties may attempt to copy aspects of our products or to obtain
and use information that we regard as proprietary. There can be no assurance
that our means of protecting our proprietary rights will be adequate or that our
competitors will not independently develop similar technology, duplicate our
products or design around patents issued to us or our other intellectual
property rights.

INTERNATIONAL SALES AND OPERATIONS INVOLVE RISKS NOT EXPERIENCED
IN DOMESTIC OPERATIONS

     Sales to customers outside the United States have accounted for significant
portions of our net sales, and we expect that the acquisition of companies
headquartered and operating in the United Kingdom and The Netherlands,
respectively, will result in international sales representing an increasingly
significant portion of our 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
our products less price competitive. If in the future we denominate any of our
sales in foreign currencies, this could result in losses from foreign currency
transactions. International sales also could be harmed by factors beyond our
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 our intellectual property rights to the same extent as the laws of the
United States. We do not believe these additional risks are significant in the
United Kingdom or in The Netherlands.

LOSS OF KEY PERSONNEL COULD HARM OUR BUSINESS

     Our future performance depends in significant part upon the continued
service of our key technical and senior management personnel. We provide
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 our officers or other key employees
could harm our business. Our future success also depends on our continuing
ability to attract and retain highly qualified technical and management
personnel. Competition for such personnel is intense, and there can be no
assurance that we can retain our key technical and management employees or that
we can attract, assimilate and retain other highly qualified technical and
management personnel in the future.

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


                                      4.

ANTI-TAKEOVER PROVISIONS COULD DISCOURAGE TENDER OFFER OR TAKEOVER ATTEMPTS,
INCLUDING THOSE THAT MIGHT RESULT IN A PREMIUM OVER MARKET PRICE

     Certain provisions of our Articles of Incorporation, as amended and
restated, and Bylaws, as amended, California law and our indemnification
agreements with our officers and directors may be deemed to have an
anti-takeover effect. Such provisions may delay, defer or prevent a tender offer
or takeover attempt that a stockholder might consider to be in that
stockholder's best interests, including attempts that might result in a premium
over the market price for the shares held by stockholders.

     Our 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 as determined by the Board of
Directors without stockholder approval.

     Our Board of Directors 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 for each outstanding
share of our common stock. Each purchase right entitles the registered holder to
purchase one one-hundredth of a share of Series A Junior Participating Preferred
Stock at an exercise price of $69.50 per one one-hundredth of a preferred share,
subject to adjustment, and a redemption price of $.01 per purchase 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 purchase 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 have acquired beneficial ownership of 15% or
more of the outstanding common stock 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 or entity acquires 15% or more of our outstanding common stock)
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 a person or group of 15% or more of such outstanding common stock.

     The purchase rights have certain anti-takeover effects, as they would cause
substantial dilution to a person or group that attempted to acquire Zitel on
terms not approved by our Board of Directors. The purchase rights should not
interfere with any merger or other business combination approved by the Board of
Directors, since the purchase rights may be redeemed at $.01 per purchase right
prior to the earliest of (i) the twentieth day following the time that a person
or group has acquired beneficial ownership of 15% or more of our outstanding
common stock (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
purchase rights.

                    THE SERIES B CONVERTIBLE PREFERRED STOCK

     On August 27, 1999, we sold 200,000 shares of our Series B Convertible
Preferred Stock to the selling securityholders named in this prospectus. These
shares of preferred stock:

     -    have liquidation preferences of $10.00 per share plus any declared and
          unpaid dividends over all other current classes of stock;

     -    provide for non-cumulative dividends of $.30 per share, if, as and
          when declared;

     -    have no voting rights except to the extent required by California law;

     -    are subject to redemption of all, but not less than all, of the
          outstanding shares of preferred stock at our option at any time at a
          liquidation price of $10.00 per share plus declared and unpaid
          dividends;

     -    are convertible at the option of the holder into the number of shares
          of Common Stock of the Company equal to the quotient obtained by
          dividing the liquidation preference by a conversion price based on the
          conversion formula described below.

     The conversion formula is based on the closing price of our common stock on
the effective date of the registration statement of which this prospectus is a
part and the closing price on the day prior to date of conversion. Under the
formula, the baseline price is $__________. On the effective date and for the
first 180 days thereafter, the conversion price is equal to the closing price on
the trading day prior to the date of conversion. However, during that 180-day
period, the conversion price shall not be less than 70% of the baseline price
and shall not be more than the closing price on the trading day prior to the
date of conversion plus one half of the amount by which the closing price
exceeds 130% of the baseline price. After that 180-day period, the conversion
price is equal to the closing price on the trading day prior to the day of
conversion, provided it shall not be less than the baseline price. The
conversion price is subject to antidilution and similar adjustments.

                                    BUSINESS

     We are an information technology company specializing in performance
management of enterprise information systems. We employ our core competencies
through Datametrics software products and services business, marketing
multi-platform performance analysis and correlation software used to optimize

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

     We develop, market and support a wide range of data management solutions in

combination of Datametrics Systems Corporation and Palmer & Webb Systems
companies, which were acquired in 1997 and combined with our Performance and
Modeling, Inc. subsidiary. The business operates under the Datametrics Systems
Corporation name. This business markets a suite of ViewPoint software utilized
for data management that automatically alerts, analyzes, correlates,

geographical map of the route and the performance of each portion of the route.
VisualRoute can be installed on a client PC to determine connectivity and

DPS will provide performance management for its clients enterprise on an
outsource basis.

                                    MARKETING

     We sell our software products through a direct sales force in the United
States, the United Kingdom and The Netherlands, and through value added
resellers, distributors and original equipment manufacturers worldwide. We
provide direct customer maintenance and support for our software products.

                                    EMPLOYEES

     At September 30, 1999, we 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.

     We believe that our further success will depend, in part, on our ability to
attract and retain qualified employees, who are in great demand. None of our
employees are represented by a labor union and we believe that our employee
relations are good.

                              PLAN OF DISTRIBUTION

     The common stock issuable upon conversion of the Series B preferred stock
may be sold from time to time by the selling securityholders in one or more
transactions at fixed prices, at market prices at the time of sale, at varying
prices determined at the time of sale or at negotiated prices. The selling
securityholders may offer their common stock in one or more of the following
transactions directly or through underwriters, broker dealers or agents:

     -    On any national securities exchange or quotation service on which our
          common stock may be listed or quoted at the time of sale, including
          the Nasdaq SmallCap Market;

     -    In the over-the-counter market;

     -    In private transactions;

     -    Through options;

     -    By pledge to secure debts or other obligations; or

     -    A combination of any of the above transactions.

     The selling securityholders may effect these transactions by selling to or
through one or more underwriters, broker-dealers or agents, and such
underwriters, broker-dealers or agents may receive compensation in the form of
underwriting discounts, concessions or commissions from the selling
securityholders. The selling securityholders and any other persons that
participate in the distribution may at times, be deemed to be "underwriters"
within the meaning of the Securities Act of 1933, and any commissions received
by such broker-dealers and any profits realized on any resale of the common
stock by them might be deemed to be underwriting discounts and commissions under
the Securities Act.

     Under applicable rules and regulations under the Securities Exchange Act,
any person engaged in the distribution of the common stock may not
simultaneously engage in market making activities with respect to our common
stock for a period of two business days prior to the commencement of such
distribution. In addition and without limiting the foregoing, the selling
securityholders and any other person participating in a distribution will be
subject to application provisions of the Securities Exchange Act and the rules
and regulations thereunder, including without limitation, Regulation M under the
Securities Exchange Act, which may limit the timing of purchases and sales of
shares of our common stock by the selling securityholders or any such other
person.

     We will make copies of this prospectus available to the selling
securityholders and have informed the selling securityholders of the need for
delivery of a copy of this prospectus to each purchaser prior to or at the time
of any sale of the common stock.

     The selling securityholders will pay all underwriting discounts,
commissions, transfer taxes and other expenses associated with the sale of the
common stock by them. We will pay all costs and expenses associated with the
registration of the common stock. We estimate that our expenses in connection
with this offering will be approximately $30,000.00.

by the Selling Securityholders.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     The Registrant's Amended and Restated Articles of Incorporation and
Bylaws include provisions to (i) eliminate the personal liability of its
directors for monetary damages resulting from breaches of their fiduciary
duty to the extent permitted by California law and (ii) require the
Registrant to indemnify its directors and officers to the fullest extent
permitted by California law, including circumstances in which indemnification
is otherwise discretionary. Pursuant to California law, a corporation
generally has the power to indemnify its present and former directors,
officers, employees and agents against expenses incurred by them in
connection with any suit to which they are, or are threatened to be made, a
party by reason of their serving in such positions so long as they acted in
good faith and in a manner they reasonably believed to be in, or not opposed
to, the best interests of a corporation, and, with respect to any criminal
action, they had no reasonable cause to believe their conduct was unlawful.
The Registrant believes that these provisions are necessary to attract and
retain qualified persons as directors and officers. These provisions do not
eliminate liability for breach of the director's duty of loyalty to the
Registrant or its stockholders, for acts or omissions not in good faith or
involving intentional misconduct or knowing violations of law, for any
transaction from which the director derived an improper personal benefit or
for any willful or negligent payment of any unlawful dividend or any unlawful
stock purchase agreement or redemption.

ITEM 17. UNDERTAKINGS.

         The undersigned registrant hereby undertakes:

(1)      To file, during any period in which offers or sales are being made, a
         post-effective amendment to this registration statement: (i) To include
         any prospectus required by section 10(a)(3) of the Securities Act of
         1933; (ii) To reflect in the prospectus any


                                    II-1.
<PAGE>

         facts or events arising after the effective date of the registration
         statement (or the most recent post-effective amendment thereof)
         which, individually or in the aggregate, represent a fundamental
         change in the information set forth in the registration statement;
         (iii) To include any material information with respect to the plan
         of distribution not previously disclosed in the registration
         statement or any material change to such information in the
         registration statement. PROVIDED, HOWEVER, the foregoing undertaking
         shall not apply if the information required to be included in a
         post-effective amendment by the foregoing paragraphs is contained in
         periodic reports filed with or furnished to the Commission by the
         registrant pursuant to section 13 or section 15(d) of the Securities
         Exchange Act of 1934 that are incorporated by reference in the
         registration statement.

(2)      That, for the purpose of determining any liability under the Securities
         Act, each post-effective amendment that contains a form of prospectus
         shall be deemed to be a new registration statement relating to the
         securities offered therein, and the offering of such securities at that
         time shall be deemed to be the initial bona fide offering thereof; and

(3)      To remove from registration by means of a post-effective amendment any
         of the securities being registered which remain unsold at the
         termination of the offering. The undersigned registrant hereby
         undertakes that, for purposes of determining any liability under the
         Securities Act of 1933, each filing of the registrant's annual report
         pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of
         1934 (and, where applicable, each filing of an employee benefit plan's
         annual report pursuant to Section 15(d) of the Securities Exchange Act
         of 1934) that is incorporated by reference in the registration
         statement shall be deemed to be a new registration statement relating
         to the securities offered therein, and the offering of such securities
         at that time shall be deemed to be the initial bona fide offering
         thereof. Insofar as indemnification for liabilities arising under the
         Securities Act may be permitted to directors, officers and controlling
         persons of the registrant pursuant to provisions described in Item 15,
         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 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 Securities Act and will be governed by the
         final adjudication of such issue.

Ladies and Gentlemen:

You have requested our opinion with respect to certain matters in connection
with the filing by Zitel Corporation (the "Company") of a Registration
Statement on Form S-3 (the "Registration Statement") with the Securities and
Exchange Commission covering the offering of 4,659,897 shares (the "Shares")
of the Company's Common Stock, without par value, issuable upon the
conversion of the Company's outstanding Series B Convertible Preferred Stock
(the "Preferred Stock").

In connection with this opinion, we have examined the Registration Statement,
the Company's Amended and Restated Certificate of Incorporation and Bylaws,
and such other documents, records, certificates, memoranda and other
instruments as we deem necessary as a basis for this opinion. We have assumed
the genuineness and authenticity of all documents submitted to us as
originals, the conformity to originals of all documents submitted to us as
copies thereof, and the due execution and delivery of all documents where due
execution and delivery are a prerequisite to the effectiveness thereof.

On the basis of the foregoing, and in reliance thereon, we are of the opinion
that the Shares, when issued upon conversion of the Preferred Stock in
accordance with the terms thereof, will be validly issued, fully paid and
nonassessable.

We consent to the filing of this opinion as an exhibit to the Registration
Statement and to the reference to our firm under the caption "Legal Matters"
in the Prospectus included in the Registration Statement.

Very truly yours,

COOLEY GODWARD LLP

John L. Cardoza

         4.1 REQUISITE POWER AND AUTHORITY. Purchaser has all necessary power
and authority under all applicable provisions of law to execute and deliver
this Agreement and the Registration Rights Agreement and to carry out their
provisions. All action on Purchaser's part required for the lawful execution

the Shares nor the Conversion Shares have been registered under the
Securities Act. Purchaser also understands that the Shares are being offered
and sold pursuant to an exemption from registration contained in the
Securities Act based in part upon Purchaser's representations contained in
the Agreement. Purchaser hereby represents and warrants as follows:

              (A) PURCHASER BEARS ECONOMIC RISK. Purchaser has substantial
experience in evaluating and investing in private placement transactions of
securities in companies similar to the Company so that it is capable of
evaluating the merits and risks of its investment in the Company and has the
capacity to protect its own interests. Purchaser must bear the economic risk
of this investment indefinitely unless the Shares (or the Conversion Shares)
are registered pursuant to the Securities Act, or an exemption from
registration is available. Purchaser also understands that there is no
assurance that any exemption from registration under the Securities Act will
be available and that, even if available, such exemption may not allow
Purchaser to transfer all or any portion of the Shares or the Conversion
Shares under the circumstances, in the amounts or at the times Purchaser
might propose.

              (B) ACQUISITION FOR OWN ACCOUNT. Purchaser is acquiring the
Shares and the Conversion Shares for Purchaser's own account for investment
only, and not with a view towards their distribution, provided Purchaser may
resell the Conversion Shares in a transaction which is registered under the
Securities Act or which is exempt from the registration requirements of the
Securities Act.

              (C) PURCHASER CAN PROTECT ITS INTEREST. Purchaser represents
that by reason of its, or of its management's, business or financial
experience, Purchaser has the capacity to protect its own interests in
connection with the transactions contemplated in this Agreement, and the
Related Agreements. Further, Purchaser is aware of no publication of any
advertisement in connection with the transactions contemplated in the
Agreement.

              (D) ACCREDITED INVESTOR. Purchaser represents that it is an
accredited investor within the meaning of Regulation D under the Securities
Act.

              (E) COMPANY INFORMATION. Purchaser has received and read the
SEC Filings and has had an opportunity to discuss the Company's business,
management and financial affairs with directors, officers and management of
the Company and has had the opportunity to review the Company's operations
and facilities. Purchaser has also had the opportunity to ask questions of
and receive answers from, the Company and its management regarding the terms
and conditions of this investment.

<PAGE>

              (F) RULE 144. Purchaser acknowledges and agrees that the
Shares, and, if issued, the Conversion Shares must be held indefinitely
unless they are subsequently registered under the Securities Act or an
exemption from such registration is available. Purchaser has been advised or
is aware of the provisions of Rule 144 promulgated under the Securities Act
as in effect from time to time, which permits limited resale of shares
purchased in a private placement subject to the satisfaction of certain
conditions, including, among other things: the availability of certain
current public information about the Company, the resale occurring following
the required holding period under Rule 144 and the number of shares being
sold during any three-month period not exceeding specified limitations.

              (G) RESIDENCE. The office of the Purchaser in which its
investment decision was made is located at the address or addresses of the

                                ZITEL CORPORATION

                          REGISTRATION RIGHTS AGREEMENT

         THIS REGISTRATION RIGHTS AGREEMENT (the "AGREEMENT") is entered into
as of the 3rd day of September, 1999, by and among ZITEL CORPORATION, a
CALIFORNIA corporation (the "COMPANY") and the purchasers of the Company's
Series B Convertible Preferred Stock ("SERIES B STOCK") set forth on Exhibit
A of that certain Series B Convertible Preferred Stock Purchase Agreement of
even date herewith (the "PURCHASE AGREEMENT") and the signature page hereto.
The purchasers of the Series B Stock shall be referred to hereinafter as the
"INVESTORS" and each individually as an "INVESTOR."

                                    RECITALS

         WHEREAS, the Company proposes to sell and issue two hundred thousand
(200,000) shares of its Series B Stock pursuant to the Purchase Agreement; and

         WHEREAS, as a condition of entering into the Purchase Agreement, the
Investors have requested that the Company extend to them registration rights
as set forth below.

         NOW, THEREFORE, in consideration of the mutual promises,
representations, warranties, covenants and conditions set forth in this
Agreement and in the Purchase Agreement, the parties mutually agree as
follows:

SECTION 1.     GENERAL

          1.1  DEFINITIONS.  As used in this Agreement the following terms
shall have the following respective meanings:

               "EXCHANGE ACT" means the Securities Exchange Act of 1934, as
amended.

               "FORM S-3" means such form under the Securities Act as in
effect on the date hereof or any successor registration form under the
Securities Act subsequently adopted by the SEC which permits inclusion or
incorporation of substantial information by reference to other documents
filed by the Company with the SEC.

               "HOLDER" means any person owning of record Registrable
Securities that have not been sold to the public or any assignee of record of
such Registrable Securities in accordance with Section 2.5 hereof.

               "REGISTER," "REGISTERED," and "REGISTRATION" refer to a
registration effected by preparing and filing a registration statement in
compliance with the Securities Act, and the declaration or ordering of
effectiveness of such registration statement or document.

               "REGISTRABLE SECURITIES" means Common Stock of the Company
issued or issuable upon conversion of the Shares. Notwithstanding the
foregoing, Registrable Securities


                                       1.
<PAGE>

shall not include any securities sold by a person to the public either
pursuant to a registration statement or Rule 144 or sold in a private
transaction in which the transferor's rights under Section 2 of this
Agreement are not assigned.

               "REGISTRABLE SECURITIES THEN OUTSTANDING" shall be the number
of shares determined by calculating the total number of shares of the
Company's Common Stock that are Registrable Securities and either (a) are
then issued and outstanding or (b) are issuable pursuant to conversion of
outstanding Series B Stock.

               "REGISTRATION EXPENSES" shall mean all expenses incurred by
the Company in complying with Section 2.2 hereof, including, without
limitation, all registration and filing fees, printing expenses, fees and
disbursements of counsel for the Company, blue sky fees and expenses and the
expense of any special audits incident to or required by any such
registration (but excluding the compensation of regular employees of the
Company which shall be paid in any event by the Company).

               "SEC" or "COMMISSION" means the Securities and Exchange
Commission.

               "SECURITIES ACT" shall mean the Securities Act of 1933, as
amended.

               "SELLING EXPENSES" shall mean all underwriting discounts and
selling commissions applicable to the sale.

               "SHARES" shall mean the Company's Series B Stock issued
pursuant to the Purchase Agreement and held by the Investors listed on
Exhibit A hereto and their permitted assigns.

SECTION 2.     REGISTRATION; RESTRICTIONS ON TRANSFER

          2.1  RESTRICTIONS ON TRANSFER.

               (a)  Each Holder agrees not to make any disposition of all or
any portion of the Shares or Registrable Securities unless and until:

                    (i)  There is then in effect a registration statement
under the Securities Act covering such proposed disposition and such
disposition is made in accordance with such registration statement; or

                    (ii) (A) The transferee has agreed in writing to be bound
by the terms of this Agreement, (B) such Holder shall have notified the
Company of the proposed disposition and shall have furnished the Company with
a statement of the circumstances surrounding the proposed disposition, and
(C) if reasonably requested by the Company, such Holder shall have furnished
the Company with an opinion of counsel, reasonably satisfactory to the
Company, that such disposition will not require registration of such shares
under the Securities Act.

                    (iii) Notwithstanding the provisions of paragraphs (i)
and (ii) above, no such registration statement or opinion of counsel shall be
necessary for a transfer by a Holder which is (A) a partnership to its
partners or former partners in accordance with partnership


                                       2.
<PAGE>

interests, (B) a limited liability company to its members or former members
in accordance with their interest in the limited liability company, or (C) to
the Holder's family member or trust for the benefit of an individual Holder;
PROVIDED that in each case the transferee will be subject to the terms of
this Agreement to the same extent as if the transferee were an original
Holder hereunder.

               (b)  Each certificate representing Shares or Registrable
Securities shall (unless otherwise permitted by the provisions of the
Agreement) be stamped or otherwise imprinted with a legend substantially
similar to the following (in addition to any legend required under applicable
state securities laws):

               THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN
               REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE
               "ACT") AND MAY NOT BE OFFERED, SOLD OR OTHERWISE
               TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED UNLESS
               AND UNTIL REGISTERED UNDER THE ACT OR UNLESS IN ITS
               DISCRETION THE COMPANY SHALL HAVE RECEIVED AN OPINION
               OF COUNSEL SATISFACTORY TO THE COMPANY AND ITS
               COUNSEL THAT SUCH REGISTRATION IS NOT REQUIRED.

               (c)  The Company shall be obligated to reissue promptly
unlegended certificates at the request of any holder thereof if the holder shall
have obtained an opinion of counsel reasonably acceptable to the Company to the
effect that the securities proposed to be disposed of may lawfully be so
disposed of without registration, qualification or legend.

          2.2  REGISTRATION.  The Company shall, as expeditiously as
reasonably possible:

               (a)  Prepare and file with the SEC a registration statement on
Form S-3 with respect to the Registrable Securities and use its best lawful
efforts to cause such registration statement to become effective and use its
best lawful effort to keep such registration statement continuously effective
until the 10th day of the seventh month following the day such registration
statement is first declared effective, plus one day for each day the
Adjustment Period is extended pursuant to Section E.3(d) or E.3(e) of the
Certificate of Determination of the Series B Stock, or if earlier, until the
Holder or Holders have completed the distribution pursuant thereto.

               (b)  Prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in
connection with such registration statement as may be necessary to comply
with the provisions of the Securities Act with respect to the disposition of
all securities covered by such registration statement for the period set
forth in paragraph (a) above.

               (c) Furnish to the Holders such number of copies of a
prospectus in conformity with the requirements of the Securities Act.

               (d) Use its best efforts to register and qualify the
securities covered by such registration statement under such other securities
or Blue Sky laws of such jurisdictions as shall be reasonably requested by
the Holders; PROVIDED that the Company shall not be required in


                                       3.
<PAGE>

connection therewith or as a condition thereto to qualify to do business or
to file a general consent to service of process in any such states or
jurisdictions.

               (e)  Notify each Holder of Registrable Securities covered by
such registration statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act of the happening of any
event as a result of which the prospectus included in such registration
statement, as then in effect, includes an untrue statement of a material fact
or omits to state a material fact required to be stated therein or necessary
to make the statements therein not misleading in the light of the
circumstances then existing. A notice pursuant to this Section 2.2(e) shall
be referred to herein as a "Blackout Notice."

          2.3  FURNISHING INFORMATION; COMPLIANCE WITH THE SECURITIES ACT.

               (a)  It shall be a condition precedent to the obligations of
the Company to take any action pursuant to Section 2.2, that the selling
Holders shall furnish to the Company such information regarding themselves,
the Registrable Securities held by them and the intended method of
disposition of such securities as shall be required to effect the
registration of their Registrable Securities.

               (b)  Each Holder agrees that it will comply with the
prospectus delivery requirements of the Act with respect to any sale of
Registrable Securities pursuant to the registration statement and refrain
from sales of Registrable Securities upon receipt of a Blackout Notice and
until the Company has advised that the statement or omission which gave rise
to the Blackout Notice has been cured.

          2.4  INDEMNIFICATION.  In the event any Registrable Securities are
included in a registration statement under Section 2.2:

               (a)  To the extent permitted by law, the Company will
indemnify and hold harmless each Holder, the partners, officers and directors
of each Holder, and each person, if any, who controls such Holder or
underwriter within the meaning of the Securities Act or the Exchange Act,
against any losses, claims, damages, or liabilities (joint or several) to
which they may become subject under the Securities Act, the Exchange Act or
other federal or state law, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon
any of the following statements, omissions or violations (collectively a
"VIOLATION") by the Company: (i) any untrue statement or alleged untrue
statement of a material fact contained in such registration statement,
including any preliminary prospectus or final prospectus contained therein or
any amendments or supplements thereto, (ii) the omission or alleged omission
to state therein a material fact required to be stated therein, or necessary
to make the statements therein not misleading, or (iii) any violation or
alleged violation by the Company of the Securities Act, the Exchange Act, any
state securities law or any rule or regulation promulgated under the
Securities Act, the Exchange Act or any state securities law in connection
with the offering covered by such registration statement; and the Company
will pay as incurred to each such Holder, partner, officer, director,
underwriter or controlling person for any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such loss,
claim, damage, liability or action; PROVIDED HOWEVER, that the indemnity
agreement contained in this Section 2.4(a) shall not apply to amounts paid in
settlement of any


                                       4.
<PAGE>

such loss, claim, damage, liability or action if such settlement is effected
without the consent of the Company, which consent shall not be unreasonably
withheld, nor shall the Company be liable in any such case for any such loss,
claim, damage, liability or action to the extent that it arises out of or is
based upon a Violation which occurs in reliance upon and in conformity with
written information furnished expressly for use in connection with such
registration by such Holder, partner, officer, director, underwriter or
controlling person of such Holder.

               (b)  To the extent permitted by law, each Holder will,
indemnify and hold harmless the Company, each of its directors, its officers
and each person, if any, who controls the Company within the meaning of the
Securities Act, and any other Holder selling securities under such
registration statement or any of such other Holder's partners, directors or
officers or any person who controls such Holder, against any losses, claims,
damages or liabilities (joint or several) to which the Company or any such
director, officer, controlling person, underwriter or other such Holder, or
partner, director, officer or controlling person of such other Holder may
become subject under the Securities Act, the Exchange Act or other federal or
state law, insofar as such losses, claims, damages or liabilities (or actions
in respect thereto) arise out of or are based upon any violation described in
clauses 2.4(a)(i) and (ii) above or a violation of Section 2.8 below (a
"Shareholder Violation"), in each case to the extent (and only to the extent)
that such Shareholder Violation occurs in reliance upon and in conformity
with written information furnished by such Holder under an instrument duly
executed by such Holder and stated to be specifically for use in connection
with such registration; and each such Holder will pay as incurred any legal
or other expenses reasonably incurred by the Company or any such director,
officer, controlling person, underwriter or other Holder, or partner,
officer, director or controlling person of such other Holder in connection
with investigating or defending any such loss, claim, damage, liability or
action if it is judicially determined that there was such a Shareholder
Violation; PROVIDED, HOWEVER, that the indemnity agreement contained in this
Section 2.4(b) shall not apply to amounts paid in settlement of any such
loss, claim, damage, liability or action if such settlement is effected
without the consent of the Holder, which consent shall not be unreasonably
withheld; PROVIDED FURTHER, that in no event shall any indemnity under this
Section 2.4 exceed the proceeds from the offering received by such Holder.

               (c)  Promptly after receipt by an indemnified party under this
Section 2.4 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect
thereof is to be made against any indemnifying party under this Section 2.4,
deliver to the indemnifying party a written notice of the commencement
thereof and the indemnifying party shall have the right to participate in,
and, to the extent the indemnifying party so desires, jointly with any other
indemnifying party similarly noticed, to assume the defense thereof with
counsel mutually satisfactory to the parties; PROVIDED, HOWEVER, that an
indemnified party shall have the right to retain its own counsel, with the
fees and expenses to be paid by the indemnifying party, if representation of
such indemnified party by the counsel retained by the indemnifying party
would be inappropriate due to actual or potential differing interests between
such indemnified party and any other party represented by such counsel in
such proceeding. The failure to deliver written notice to the indemnifying
party within a reasonable time of the commencement of any such action, if
materially prejudicial to its ability to defend such action, shall relieve
such indemnifying party of any liability to the indemnified party under this
Section 2.4, but the omission so to deliver written notice to the


                                       5.
<PAGE>

indemnifying party will not relieve it of any liability that it may have to
any indemnified party otherwise than under this Section 2.4.

               (d)  If the indemnification provided for in this Section 2.4
is held by a court of competent jurisdiction to be unavailable to an
indemnified party with respect to any losses, claims, damages or liabilities
referred to herein, the indemnifying party, in lieu of indemnifying such
indemnified party thereunder, shall to the extent permitted by applicable law
contribute to the amount paid or payable by such indemnified party as a
result of such loss, claim, damage or liability in such proportion as is
appropriate to reflect the relative fault of the indemnifying party on the
one hand and of the indemnified party on the other in connection with the
Violation(s) that resulted in such loss, claim, damage or liability, as well
as any other relevant equitable considerations. The relative fault of the
indemnifying party and of the indemnified party shall be determined by a
court of law by reference to, among other things, whether the untrue or
alleged untrue statement of a material fact or the omission to state a
material fact relates to information supplied by the indemnifying party or by
the indemnified party and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission;
PROVIDED, that in no event shall any contribution by a Holder hereunder
exceed the proceeds from the offering received by such Holder.

               (e)  The obligations of the Company and Holders under this
Section 2.4 shall survive completion of any offering of Registrable
Securities in a registration statement and the termination of this agreement.
No Indemnifying Party, in the defense of any such claim or litigation, shall,
except with the consent of each Indemnified Party, consent to entry of any
judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party of a release from all liability in respect to such claim or
litigation.

          2.5  ASSIGNMENT OF REGISTRATION RIGHTS.  The rights to cause the
Company to register Registrable Securities pursuant to this Section 2 may be
assigned by a Holder to a transferee or assignee of Registrable Securities
which (a) is a subsidiary, parent, general partner, limited partner, retired
partner, member or retired member of a Holder, (b) is a Holder's family
member or trust for the benefit of an individual Holder, (c) controls, is
controlled by or is under common control with the holder and acquires at
least five thousand (5,000) shares of Registrable Securities (as adjusted for
stock splits and combinations); PROVIDED, HOWEVER, (i) the transferor shall,
within ten (10) days after such transfer, furnish to the Company written
notice of the name and address of such transferee or assignee and the
securities with respect to which such registration rights are being assigned
and (ii) such transferee shall agree to be subject to all restrictions set
forth in this Agreement.

          2.6  AMENDMENT OF REGISTRATION RIGHTS.  Any provision of this
Section 2 may be amended and the observance thereof may be waived (either
generally or in a particular instance and either retroactively or
prospectively), only with the written consent of the Company and the Holders
of at least a majority of the Registrable Securities then outstanding. Any
amendment or waiver effected in accordance with this Section 2.6 shall be
binding upon each Holder and the Company. By acceptance of any benefits under
this Section 2, Holders of Registrable Securities hereby agree to be bound by

this Agreement should, for any reason, be held to be invalid, illegal or
unenforceable in any respect, such invalidity, illegality, or

to exercise any right, power, or remedy accruing to any Holder, upon any
breach, default or noncompliance of the Company under this Agreement shall
impair any such right, power, or remedy, nor shall it be construed to be a

therein, or of any similar breach, default or noncompliance thereafter
occurring. It is further agreed that any waiver, permit, consent, or approval
of any kind or character on any Holder's part of any breach, default or

fees and expenses of attorneys and accountants, which shall include, without
