___________________________
___________________________
___________________________

Dear _______________:

      This will confirm our understanding as follows:

      You agree that you are willing to become a member of a slate of nominees
(the "Slate") of BKF Capital Group, Inc. (the "Nominating Party" or "BKF"), to
stand for election as directors of Qualstar Corporation (TICKER: QBAK) (the
"Company") in connection with a possible proxy solicitation (the "Proxy
Solicitation") to be conducted by BKF and certain related parties in respect of
the special meeting of stockholders of the Company (including any adjournment or
postponement thereof or any special meeting held in lieu thereof, the "Meeting")
or in connection with a possible solicitation of written consents (the "Consent
Solicitation") to elect directors without a meeting. You further agree to serve
as a director of the Company if elected. BKF, along with its affiliates, agrees
to pay the costs of the Proxy Solicitation or Consent Solicitation.

      You understand that it may be difficult, if not impossible, to replace a
nominee who, such as yourself, has agreed to serve on the Slate and, if elected,
as a director of the Company if such nominee later changes his mind and
determines not to serve on the Slate or, if elected, as a director of the
Company. Accordingly, BKF is relying upon your agreement to serve on the Slate
and, if elected, as a director of the Company.

      In that regard, you are being supplied with a questionnaire (a
"Questionnaire") in which we request that you provide information necessary for
the Nominating Party to make appropriate disclosure to the Company and to use in
creating the proxy materials to be sent to stockholders of the Company and filed
with the Securities and Exchange Commission in connection with the Proxy
Solicitation or the consent materials to be sent and filed in connection with
the Consent Solicitation. You agree that your responses in the Questionnaire
will be true, complete and correct in all respects. We may forward your
completed Questionnaire and executed consent (attached hereto) or summaries
thereof to the Company, and we may disclose such information, as well as the
existence and contents of this letter.

                                      -7-


      The Nominating Party shall provide you with a final or near-final draft of
the initial proxy materials to be sent to stockholders of the Company and filed
with the Securities and Exchange Commission, as to each set of materials (in the
event there is more than one set) no later than one business day prior to that
set of materials being sent, filed or otherwise made public.

      The Nominating Party agrees to defend, indemnify and hold you harmless
from and against any and all losses, claims, damages, penalties, judgments,
awards, settlements, liabilities, costs, expenses and disbursements incurred by
you and to advance (i) in the event that you become a party, or are threatened
to be made a party, to any civil, criminal, administrative or arbitrative
action, suit or proceeding, and any appeal thereof relating to your role as a
nominee for director of the Company on the Slate (a "Proceeding"), (ii) in the
event you are called to testify or give a deposition in any Proceeding (whether
or not you are a party or are threatened to be made a party to such Proceeding),
or (iii) otherwise arising from or in connection with or relating to the Proxy
Solicitation or Consent Solicitation, to you all reasonable attorneys' costs and
expenses incurred by you as and when incurred by you.

      Your rights of indemnification and advancement hereunder shall continue
(i) in the event that the Nominating Party determines to withdraw the Slate or
remove you from the Slate and (ii) after the Meeting or consent in lieu of the
Meeting has taken place, in all events for events which occur prior to the
Meeting or consent in lieu of the Meeting and subsequent to the date hereof.

      Anything to the contrary herein notwithstanding, the Nominating Party is
not indemnifying you for any action taken by you or on your behalf that occurs
prior to the date hereof or subsequent to the conclusion of the Proxy
Solicitation or Consent Solicitation or such earlier time as you are no longer a
nominee on the Slate for election to the Company's Board of Directors or for any
actions taken by you as a director of the Company if you are elected. Nothing
herein shall be construed to provide you with indemnification: (i) if you are
found to have engaged in a violation of any provision of state or federal law in
connection with the Proxy Solicitation or Consent Solicitation unless you
demonstrate that your action was taken in good faith and in a manner you
reasonably believed to be in or not opposed to the best interests of electing
the Slate; (ii) the Proceeding involves conduct by you that constitutes gross
negligence or willful misconduct; or (iii) the Proceeding involves your having
provided false or misleading information, or omitted material information, in
the Questionnaire or otherwise in connection with the Proxy Solicitation or
Consent Solicitation.

      You shall promptly notify the Nominating Party in writing in the event of
any third-party claims actually made against you or known by you to be
threatened if you intend to seek indemnification hereunder in respect of such
claims, but no delay in delivering such notification shall relieve BKF of its
indemnification obligations hereunder, except to the extent that it is actually
prejudiced by such delay.

                                      -8-


      In addition, with respect to any such claim, the Nominating Party shall be
entitled to control your defense with counsel chosen by BKF, unless you shall
have reasonably concluded that there exists an actual or potential conflict
between you and the Nominating Party, and there may be defenses available to you
which are different from or additional to those available to the Nominating
Party, in which case the Nominating Party shall not have the right to control
the defense of such claim on your behalf, you shall have the right to employ
your own counsel reasonably satisfactory to BKF, and BKF shall pay the
reasonable fees and expenses of not more than one firm of attorneys employed by
you.

      The Nominating Party shall not be responsible for any settlement of any
claim against you covered by this indemnity without its prior written consent.
However, the Nominating Party may not enter into any settlement of any such
claim without your consent unless such settlement includes (i) no admission of
liability or guilt by you and (ii) a release of you from any and all liability
in respect of such claim.

      Each of us recognizes that should you be elected to the Board of Directors
of the Company, all of your activities and decisions as a director will be
governed by applicable law and subject to your fiduciary duties, as applicable,
to the Company and to the stockholders and other constituents of the Company
and, as a result, that there is, and can be, no agreement between you and the
Nominating Party or related parties that governs the decisions which you will
make as a director of the Company.

      You agree that this letter and its contents will remain confidential and
the Proxy Solicitation, Consent Solicitation, the existence of this letter and
the provisions hereof will not be directly or indirectly discussed with or
disclosed by you to any third party (other than legal counsel of yours who is
aware of the requirements of this paragraph) unless and until the Nominating
Party or its affiliates shall make a public statement, announcement, or
