                                 June 16, 1998


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 May 8, 1998 through and including June 30, 
1998 (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. $20,000,000.00 
aggregate principal amount of the Company's 3% Convertible Subordinated 
Debentures Due 1999 (the "Debentures"), convertible into shares of the 
Company's common stock, no par value per share (the "Common Stock"), and up 
to 300,000 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 shall be as set forth in the subscription 
documents, including the convertible debenture purchase agreement, 
convertible subordinated debenture, registration rights agreement, and common 
stock purchase warrant, to be executed 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



Rochon Capital Group, Ltd.

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 July 7, 1998 without the written consent of the 
Company and the Placement Agent and provided further that to the extent the 
Subscription Documents contemplate a second closing, the terms of this 
Agreement shall apply to such second closing (and herein reference to the 
"Closing" shall be deemed to include each of the first and second such 
closing unless the text specifically indicates otherwise).

     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 ("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 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 transactions 
contemplated herein, the Company agrees to pay the Placement Agent, directly 
from the escrowed funds at the Closing, a fee of 4.0% of the gross proceeds 
from the sale of the Securities on the first $6,000,000.00 raised, 3.5% of 
the gross proceeds from the sale of the Securities on amounts between 
$6,000,001.00 and $20,000,000.00, and 3.0% of the gross proceeds from the 
sale of the Securities on amounts in excess of $20,000,000.00 (the "Agency 
Fee"). The parties hereto expressly agree that the gross proceeds from the 
sale of the Securities at a second closing shall be subject to compensation 
as provided in this Section 4 on a cumulative basis with the gross proceeds 
of the first closing and the fee so paid in respect of the first and second 
Closings shall collectively be referred to herein as the "Agency Fee". In 
addition, the Company agrees to pay to the Placement Agent, directly from 




Rochon Capital Group, Ltd.
June 16, 1998
Page 4

the escrowed funds at the first Closing, an expense allowance of $19,500.00 
and directly from the escrowed funds at the second Closing, an expense 
allowance of $10,000.00, each 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 (collectively, 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 own 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 in an amount not to exceed $30,000.00.

     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, 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 related to the Placement, 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 




Rochon Capital Group, Ltd.
June 16, 1998
Page 5

expense arising from 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 indemnified 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 
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.




Rochon Capital Group, Ltd.

Page 6

          (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. 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 
Paragraph 8(a) of this Agreement.

          (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 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 in 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 




Rochon Capital Group, Ltd.
June 16, 1998
Page 7

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 July 7, 1998 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,
