                                   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

         The Company has never paid cash dividends. The Company's Board of
Directors currently intends to retain any earnings for use in the Company's
business and does not anticipate paying any cash dividends in the foreseeable
future. The Company's 3% Convertible Subordinated Debentures prohibit the
payment of dividends.

                                  RISK FACTORS

         AN INVESTMENT IN THE COMPANY INVOLVES A HIGH DEGREE OF RISK. THE RISK
FACTORS SET FORTH IN THE COMPANY'S REPORTS UNDER THE SECURITIES EXCHANGE ACT OF
1934, AS AMENDED, SHOULD BE CONSIDERED CAREFULLY BEFORE PURCHASING THE COMMON
STOCK OFFERED HEREBY.

                           THE DEBENTURES AND WARRANTS

         On February 3, 1999 we sold to the Selling Securityholders $5,000,000
of 3% Convertible Subordinated Debentures due February 1, 2000 and Common Stock
Purchase Warrants to acquire 75,000 shares of our Common Stock. The initial
conversion price of the Debentures is $2.593125. We will adjust the 
conversion price in the event that the conditions in both a. and b. are met:

a.  the lesser of (1) the average of the closing bid prices of the Common 
Stock for the twenty consecutive trading days prior to but excluding the 
forty-five calendar day anniversary of the effective date of the Registration 
Statement of which this Prospectus is a part (such forty-five calendar days 
to be extended one day for each day, if any, during that period on which there 
is not effective registration), and (2) the average of the closing bid prices 
of the Common Stock for the twenty consecutive trading days prior to but 
excluding April 4, 1999, is less than $2.88125; and 

b.  90% of the lesser of a(1) and a(2) above is lower than the conversion 
price

In such event, the adjusted conversion price would be 90% of the lesser of 
(1) and (2) above.

The exercise price of the Warrants is 130% of the conversion price, as it may 
be adjusted. It will initially be $3.3710625.

                                   THE COMPANY

Securityholder prior to this offering, the number of shares of Common Stock
being offered for the account of each Selling Securityholder and the number of

(1)      None of the Selling Securityholders has, or within the past three years
         has had, any position, office, or other material relationship with the
         Company or any of its predecessors and affiliates.

(2)      Assumes that all of the shares registered were allocated pro rata among
         the Selling Securityholders. Assuming no adjustments were made to the
         initial conversion price, 1,928,175 shares of Common Stock would be
         issuable upon exercise of the Warrants and conversion of the principal
         of (but not the accrued 3% interest on) the Debentures. Pursuant to the
         terms of the Debentures and the Warrants, the Debentures are
         convertible and the Warrants are exercisable by any holder only to the
         extent that the number of shares of Common Stock thereby issuable,
         together with the number of shares of Common Stock owned by such holder
         and its affiliates (but not including shares of Common Stock underlying
         unconverted Debentures or unexercised Warrants) would not exceed 4.9%
         of the then outstanding Common Stock as determined in accordance with
         Section 13(d) of the Exchange Act. Accordingly the number of shares of
         Common Stock set forth in the table for the Selling Securityholders
         exceeds the number of shares of Common Stock that the Selling
         Securityholders could own beneficially at any given time through its
         ownership of the Debentures and Warrants. In that regard, beneficial
         ownership of the Selling Securityholders set forth in the table is not
         determined in accordance with Rule 13d-3 under the Exchange Act.

(3)      Assumes the sale of all Shares offered hereby. The Company has agreed
         to pay all reasonable fees and expenses incident to the filing of this
         offering.

(4)      The shares set forth in the table are managed directly or indirectly by
         The Palladin Group, L.P. ("Palladin") or an affiliate of Palladin.
         Palladin may be deemed to be the beneficial owner of these shares
         pursuant to Section 13(d) of the Exchange Act. Palladin disclaims any
         beneficial interest in these securities. None of the Selling
         Securityholders set forth in the table has any beneficial interest in
         the shares held by any other Selling Securityholder in such table.

                              PLAN OF DISTRIBUTION


         The shares may be sold from time to time by the Selling 
Securityholders in one or more long or short 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 
shares in one or more of the following transactions:

- -    On any national securities exchange or quotation service on which the Zitel
     common stock may be listed or quoted at the time of sale, including the
     Nasdaq National 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 such transactions by selling to
or through one or more broker-dealers, and such broker-dealers may receive
compensation in the form of underwriting discounts, concessions or commissions
from the Selling Securityholders. The Selling Securityholders and any
broker-dealers that participate in the distribution may, under certain
circumstances, be deemed to be "underwriters" within the meaning of the
Securities Act, and any commissions received by such broker-dealers and any
profits realized on any resale of the shares by them might be deemed to
be underwriting discounts and commissions under the Securities Act.

         Under applicable rules and regulations under the Exchange Act, any
person engaged in the distribution of the shares may not simultaneously
engage in market making activities with respect to Zitel Corporation's 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
Exchange Act, which may limit the timing of purchases and sales of shares of
Zitel 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 or the shares
prior to or at the time of any sale of the shares.

         The Selling Securityholders will pay all underwriting discounts,
commissions, transfer taxes and other expenses associated with the sale of the
shares by them. We will pay all costs and expenses associated with the
registration of the shares. We estimate that our expenses in connection
with this offering will be approximately $22,000.00.
