                           Common Stock Purchase Warrants

                             PLACEMENT AGENCY AGREEMENT

                                  February 1, 1999

Rochon Capital Group, Ltd.
  As Placement Agent
16 Mary Street, Suite 2000
San Rafael, California  94901

Ladies and Gentlemen:

     This letter confirms the agreement (this "Agreement") of Zitel 
Corporation, a California corporation (the "Company"), to retain Rochon 
Capital Group, Ltd., a California corporation (the "Placement Agent"), as the 
Company's exclusive agent from February 1, 1999 through and including March 
1, 1999 (the "Engagement Period") to identify for the Company prospective 
purchasers (collectively, the "Purchasers" and each individually, a 
"Purchaser") in a placement (the "Placement") of up to U.S. $5,000,000.00 
aggregate principal amount of the Company's 3% Convertible Debentures Due 
2000 (the "Debentures") convertible into shares of the Company's common 
stock, no par value per share (the "Common Stock"), and up to 75,000 warrants 
(the "Warrants") exercisable into shares of Common Stock.  The Debentures and 
Warrants are collectively referred to herein as the "Securities."

     Terms of the Placement are set forth in the subscription documents, 
including the convertible debenture purchase agreement, convertible 
subordinated debenture, registration rights agreement, and common stock 
purchase warrant, issued in connection with the Placement (collectively, the 
"Subscription Documents").

     The Placement Agent will act on a best efforts basis and will have no 
obligation to purchase any of the Securities offered by the Company in the 
Placement.  During the Engagement Period, the Placement Agent shall have the 
exclusive right to make all offers and to arrange for all sales of securities 
by the Company, including without limitation the exclusive right to identify 
buyers for the Securities.  The Engagement Period shall be automatically 
extended for a reasonable number of days if, during the Engagement Period, 
sales relating to commitments from Purchasers are not consummated during the 
Engagement Period due to delays in the preparation of final documentation; 
provided, however, that in no event will the Engagement Period be 
automatically extended beyond March 15, 1999 without the written consent of 
the Company and the Placement Agent.

     The Placement is intended to be exempt from the registration 
requirements of the Securities Act of 1933, as amended (the "Securities 
Act"), pursuant to Regulation D 



Rochon Capital Group, Ltd.
February 1, 1999

("Regulation D") of the rules and regulations of the Securities and Exchange 
Commission (the "SEC") promulgated under the Securities Act.

     In order to effectuate the Closing (as defined in Section 1 hereof), the 
Company, the Placement Agent and a bank reasonably acceptable to both parties 
(the "Escrow Agent") shall enter into an escrow agreement (the "Escrow 
Agreement").

     The engagement described herein shall be in accordance with applicable 
laws and pursuant to the following procedures, terms and conditions:

     1.   REPRESENTATIONS AND WARRANTIES OF THE COMPANY.   The 
representations and warranties of the Company made to the Purchasers as set 
forth in the Subscription Documents are hereby incorporated by reference as 
of the date of consummation of the sale of the Securities (the "Closing") and 
all such representations and warranties are hereby deemed made by the Company 
directly to the Placement Agent as though set forth in full herein.

     2.   COVENANTS OF THE COMPANY.

          (a)  The covenants of the Company made to the Purchasers as set 
forth in the Subscription Documents are hereby incorporated by reference as 
of the Closing and all such covenants are hereby deemed made by the Company 
directly to the Placement Agent as though set forth in full herein.

          (b)  Neither the Company nor any affiliate of the Company (as 
defined in Rule 501(b) of Regulation D) will sell, offer for sale or solicit 
offers to buy or otherwise negotiate in respect of any security (as defined 
in the Securities Act) which will be integrated with the sale of the 
Securities or the shares of Common Stock issuable upon conversion of the 
Debentures or exercise of the Warrants (the "Underlying Common Shares") in a 
manner which would require the registration under the Securities Act of the 
Securities or the Underlying Common Shares.

          (c)  Any and all filings and documents required to be filed in 
connection with or as a result of the Placement pursuant to federal and state 
securities laws are the responsibility of the Company and will be filed by 
the Company.

          (d)  Any press release to be issued by the Company announcing or 
referring to the Placement shall be subject to the prior review of the 
Placement Agent, and each such press release shall, at the request of the 
Placement Agent, identify Rochon Capital Group, Ltd. as the placement agent.  
This Agreement shall not be filed publicly by the Company without the prior 
written consent of the Placement Agent.

     3.   COVENANTS OF THE PLACEMENT AGENT.   On the basis of, and in 
reliance on, the representations, warranties and covenants of the Purchasers 
set forth in the Subscription Documents, the Placement Agent hereby covenants 
with the Company as follows:

          (a)  The Placement Agent will take no action, nor fail to take any 
action, if such action or failure to take such action would have the effect 
that the offer or sale of the 



Rochon Capital Group, Ltd.

Page 3


Securities would not be exempt from the registration requirements of the 
Securities Act pursuant to Regulation D.

          (b)  No action is being taken or is contemplated by the Placement 
Agent that would permit a public offering of the Securities in any 
jurisdiction where, or in any other circumstance in which, action for those 
purposes is required (other than in jurisdictions where such action has been 
duly taken). The Placement Agent will comply with applicable laws and 
regulations in any jurisdiction in which it may offer, sell or deliver the 
Securities and will not, directly or indirectly, offer, sell or deliver the 
Securities or distribute or publish any prospectus, circular, advertisement 
or other offering material in relation to the Securities in or from any 
country or jurisdiction except under circumstances that will result in 
compliance with any applicable laws and regulations, and all offers, sales 
and deliveries of the Securities by it will be made on the foregoing terms.

     4.   COMPENSATION OF THE PLACEMENT AGENT; EXPENSES.   As compensation 
for services rendered by the Placement Agent in connection with the 
transaction contemplated herein, the Company agrees to pay the Placement 
Agent, directly from the escrowed funds at the Closing, a fee of 3.5% of the 
gross proceeds from the sale of the Securities (the "Agency Fee").  In 
addition, the Company agrees to pay to the Placement Agent, directly from the 
escrowed funds at the Closing, an expense allowance of $10,000.00 as 
reimbursement for the Placement Agent's expenses, including without 
limitation attorney fees and costs, travel-related expenses and estimated 
telephone, facsimile and postage charges (the "Expense Reimbursement").  
Costs incurred by the Placement Agent in excess of the Expense Reimbursement 
shall be the Placement Agent's sole responsibility.  The Company will pay all 
of its expenses incurred in connection with the Placement and will also pay 
the Escrow Agent's fee and the reasonable accountable attorney fees and costs 
incurred by one investor.

     5.   CLOSING.  The Closing may be held at such place or places as shall 
be specified by the Placement Agent and reasonably agreed to by the Company. 
Certificates evidencing the Securities in the names of the respective 
Purchasers and in the respective denominations aggregating all of the 
Securities sold at the Closing shall be delivered by the Company to the 
Escrow Agent.

     6.   CONDITIONS TO CLOSING.   The Company and the Placement Agent agree 
that the issuance and sale of the Securities and all obligations of the 
Placement Agent provided herein shall be subject to the receipt by the 
Placement Agent of (i) a legal opinion of the Company's securities counsel, 
indicating that the Placement Agent is entitled to rely thereon, in the form 
required to be delivered to the Purchasers pursuant to the Subscription 
Documents and (ii) an escrow agreement duly executed by the Company in a form 
reasonably satisfactory to the Placement Agent.

     7.   INDEMNIFICATION.

          (a)  The Company will indemnify and hold harmless the Placement 
Agent and each of its partners, directors, officers, associates, affiliates , 
subsidiaries, divisions, employees, 



Rochon Capital Group, Ltd.

consultants, attorneys and agents, and each person, if any, controlling 
either the Placement Agent or any of its affiliates within the meaning of 
either Section 15 of the Securities Act or Section 20 of the Securities 
Exchange Act of 1934, as amended (the "Exchange Act"), from and against any 
and all losses, claims, damages, liabilities, costs or expenses (and any 
legal or other expenses incurred by the Placement Agent in investigating or 
defending the same or in giving testimony or furnishing documents in response 
to a request of any government agency or to a subpoena) in any way relating 
to or in any way arising out of (i) the activities of the Placement Agent 
contemplated by this Agreement or in connection with the Placement, (ii) the 
inaccuracy of any representation or warranty, or the breach of any covenant, 
contained herein, or (iii) any offering documents or offering materials; and 
will reimburse, as incurred, the Placement Agent and each such controlling or 
other person for any legal or other expenses incurred by the Placement Agent 
or such controlling or other person in connection with investigating, 
defending or appearing as a third-party witness in connection with any such 
loss, claim, damage, liability or action.  Such indemnity shall not, however, 
cover any such loss, claim, damage, liability, cost or a breach by the 
Placement Agent of its obligations in Section 3 hereof (a "Non-Indemnity 
Event") or the willful misconduct of any person seeking indemnification 
hereunder.

          (b)  The Placement Agent will indemnify and hold harmless the 
Company and each person, if any, controlling the Company within the meaning 
of either Section 15 of the Securities Act or Section 20 of the Exchange Act, 
to the same extent set forth in subsection (a) above, but only to the extent 
that any loss, claim, damage, liability, cost or expense arises out of or is 
based upon a Non-Indemnity Event.

          (c)  If any action, proceeding or investigation is commenced by a 
third party as to which the indemnified party hereunder proposes to demand 
indemnification under this Agreement, it will notify the indemnifying party 
with reasonable promptness.  The indemnified party shall have the right to 
retain counsel of its own choice (which choice shall be reasonably 
satisfactory to the indemnifying party) to represent it and such counsel 
shall, to the extent consistent with its professional responsibilities, 
cooperate with the indemnifying party and any counsel designated by the 
indemnifying party.  The indemnifying party will not be liable under this 
Agreement for any settlement of any claim against the indemnifying party made 
without the indemnifying party's written consent, which consent shall not be 
unreasonably withheld. Notwithstanding anything to the contrary contained in 
the foregoing subsection (b) or the following subsection (d), the Placement 
Agent shall not be obligated to pay, and will not pay, any amount in respect 
of its obligation to indemnify or contribute greater than the Agency Fee (as 
defined in Section 4 hereof).

          (d)  In order to provide for just and equitable contribution, if a 
claim for indemnification pursuant to this Section 7 is made but it is found 
in a final judgment by a court of competent jurisdiction (not subject to 
further appeal) that such indemnification may not be enforced in such case, 
even though the express provisions hereof provided for indemnification in 
such case, then the Company, on the one hand, and the Placement Agent, on the 
other hand, shall contribute to the losses, claims, damages, liabilities or 
costs to which the indemnified persons may be subject in accordance with the 
relative benefits received from the Placement of the Securities by the 
Company, on the one hand, and the Placement Agent, on the other hand, and 



Rochon Capital Group, Ltd.

also the relative fault of the Company, on the one hand, and the Placement 
Agent, on the other hand, in connection with the statements, acts or 
omissions which resulted in such losses, claims, damages, liabilities or 
costs, and the relevant equitable considerations shall also be considered.  
No person found liable for a fraudulent misrepresentation shall be entitled 
to contribution from any person who is not also found liable for such 
fraudulent misrepresentation.

     8.   NON-CIRCUMVENTION; RIGHT OF FIRST REFUSAL.

          (a)  NON-CIRCUMVENTION.  The Company hereby agrees that, for a 
period of two years form the end of the Engagement Period, the Company will 
not enter into any agreement, transaction or arrangement with any of the 
institutions (including their agents, principals and affiliates and the 
accounts and funds which they manage or advise) which the Placement Agent has 
identified to the Company as prospective purchasers of the Securities in the 
Placement (collectively, the "Rochon Contacts"), regardless of whether a 
transaction is consummated with such prospective purchasers, unless the 
Company notifies the Placement Agent in writing of the agreement, transaction 
or arrangement, and pays the Placement Agent the Agency Fee set forth in 
Paragraph 4 hereof.  Within five business days after the expiration of the 
Engagement Period, the Placement Agent will provide the Company with a list 
of the Rochon Contacts, which list and names the Company agrees to hold 
strictly confidential.  Notwithstanding the foregoing, the parties agree that 
the prospective purchasers whose names appear on the list submitted to the 
Company by the Placement Agent in a letter dated May 23, 1997 shall continue 
to be subject to the provisions of Section 8(a) of the placement agency 
agreement by and between the Company and the Placement Agent dated May 19, 
1997, and shall not be subject to the two-year limitation referred to in the 
first sentence of Section 8(a) of this Agreement; and, in addition, the 
parties agree that the list of prospective purchasers whose names appear in a 
letter to the Company from the Placement Agent dated June 19, 1998 shall be 
deemed to have been delivered to the Company by the Placement Agent within 
five business days after the expiration of the Engagement Period, as such 
term is defined in this Agreement, and the Placement Agent shall not be 
required to submit any additional lists of names in order to receive the 
non-circumvention protections described in this Section 8(a).

          (b)  RIGHT OF FIRST REFUSAL.  For a period of two hundred forty 
(240) days from the Closing Date, if the Company desires to sell any equity 
securities of the Company or any securities convertible into or exchangeable 
or exercisable for any equity securities of the Company (other than in 
connection with underwritten public offerings, acquisitions or strategic 
alliances in which the Company issues securities to potential corporate 
partners), then the Company shall offer the Placement Agent in writing the 
exclusive right to identify buyers for such securities upon terms that are 
reasonably acceptable to the Company and the Placement Agent.  The Company 
shall set forth all terms of the Subsequent Transaction in the written offer 
to the Placement Agent and the Placement Agent will then have 10 business 
days from the date of the offer to accept or reject it.  If accepted, the 
Placement Agent will have an additional 10 business days from acceptance to 
obtain commitments from investors to purchase the securities, or the Company 
will then be free to engage others to assist it in offering such securities 
on identical terms.  If the Company chooses to offer or sell securities in 
the Subsequent Transaction on terms which differ in any way from those set 
forth in the written offer to the Placement 



Rochon Capital Group, Ltd.
February 1, 1999
Page 6


Agent, then the Company must offer the Placement Agent in writing the right 
to act as the Company's exclusive agent in the Subsequent Transaction on the 
modified terms.  The foregoing notwithstanding, in the event of a Change of 
Control of the Company (as that term is defined in the Subscription 
Documents), the right of first refusal set forth in this Section 8(b) shall 
terminate.

     9.   SURVIVAL.  The respective indemnities of the Company and the 
Placement Agent and the representations, warranties and agreements of the 
Company set forth in or made pursuant to this Agreement will remain in full 
force and effect, regardless of any termination or cancellation of this 
Agreement or any investigation made by or on behalf of the Placement Agent, 
the Company or any person referred to in Section 7 hereof, and shall be 
binding upon any successors and assigns of the Company and shall survive any 
termination of this Agreement and/or issuance of the Securities.  Any 
successor or assign of the Placement Agent and/or its designees, the Company 
or any such person or any legal representative of such person shall be 
entitled to the benefit of the respective indemnities, agreements, warranties 
and representations contained herein.

     10.  TERMINATION.  Either party may terminate this Agreement by giving 
notice as hereinafter specified at any time after March 15, 1999 if the 
Closing has not occurred by such date.  In the event of termination pursuant 
to this Section 10, the Company shall remain obligated to pay the Expense 
Reimbursement as set forth in Section 4 hereof.  Subject to the foregoing 
sentence, any termination pursuant to this Section 10 shall be without 
liability of either party to the other party except as provided in the 
immediately preceding sentence.

     11.  General Provisions.

          (a)  PARTIES.  This Agreement shall inure solely to the benefit of,

person shall have or be construed to have any legal or equitable right, 
remedy or claim under or in respect of or by virtue of this Agreement or any 
provision herein contained.
