In consideration of Sands Brothers' advisory role, the Company agrees to
indemnify and hold harmless Sands Brothers, its affiliates and their respective
officers, directors, employees, agents and controlling persons (collectively,

liabilities, joint or several, related to or arising in any manner out of any
transaction, financing, proposal or any other matter (collectively, the
"Matters") contemplated by the engagement of Sands Brothers hereunder, and will
promptly reimburse the Indemnified Parties for all reasonable expenses
(including fees and expenses of legal counsel) as incurred in connection with
the investigation of, preparation for or defense of any pending or threatened
claim related to or arising in any manner out of any Matter contemplated by the
engagement of Sands Brothers hereunder, or any action or proceeding arising
therefrom (collectively, "Proceedings"), whether or not such indemnified Party
is a formal party to any such Proceeding. Notwithstanding the foregoing, the
Company shall not be liable in respect of any losses, claims, damages,
liabilities or expenses that a court of competent jurisdiction shall have
determined by final judgment resulted solely from the gross negligence or
willful misconduct of an indemnified Party. The Company further agrees that it
will not, without the prior written consent of Sands Brothers, settle,
compromise or consent to the entry of any judgment in any pending or threatened
Proceeding in respect of which indemnification may be sought hereunder (whether
or not Sands Brothers or any indemnified Party is an actual or potential party
to such Proceeding), unless such settlement, compromise or consent includes an
unconditional release of Sands Brothers and each other Indemnified Party
hereunder from all liability arising out of such Proceeding.

to this letter were for any reason not to be available to any Indemnified Party
or insufficient to hold it harmless as and to the extent contemplated by this
letter, then the Company shall contribute to the amount paid or payable by such
Indemnified Party in respect of losses, claims, damages and liabilities in such
proportion as is appropriate to reflect the relative benefits to the Company and
its stockholders on the one hand, and Sands Brothers on the other, in connection
with the Matters to which such indemnification or reimbursement relates or, if
such allocation is not permitted by applicable law, not only such relative
benefits but also the relative faults of such parties to the Company and/or its
stockholders and to Sands Brothers with respect to Sands Brother's engagement
shall be deemed to be in the same proportion as (i) the total value paid or
received or to he paid or received by the Company and/or its stockholders
pursuant to the Matters (whether or not consummated) for which Sands Brothers is
engaged to render financial advisory services bears to (ii) the fees paid to
Sands Brothers in connection with such engagement. In no event shall the
indemnified Parties contribute or otherwise be liable for an amount in excess of
the aggregate amount of fees actually received by Sands Brothers pursuant to
such engagement (excluding amounts received

The Company further agrees that no Indemnified Party shall have any liability
(whether direct of indirect, in contract or tort or otherwise) to the Company
for or in connection with Sands Brothers engagement here under except for
losses, claims, damages, liabilities or expenses that a court of competent
jurisdiction shall have determined by final judgment resulted solely from the
gross negligence or willful misconduct of such Indemnified Party. The indemnity,
reimbursement and contribution obligations of the Company shall be in addition
to any liability which the Company may otherwise have and shall be binding upon
and inure to the benefit of any successors, assigns, heirs and personal
representatives of the Company or an indemnified Party.

The indemnity, reimbursement and contribution provisions set forth herein shall
remain operative and in full force and effect regardless of (i) any withdrawal,
termination or consummation of or failure to initiate or consummate any Matter
referred to herein, (ii) any investigation made by or on behalf of any party
hereto or any person controlling (within the meaning of Section 15 of the
Securities Act of 1933, as amended, or Section 20 of the Securities Exchange Act
of 1934, as amended) any party hereto, (iii) any termination or the completion
or expiration of this letter or Sands Brothers engagement and (iv) whether or
not Sands Brothers ` shall, or shall not be called upon to, render any formal or
informal advice in the course of such engagement.

This letter constitutes the entire understanding of the parties with respect to
the subject matter hereof and may not be altered, amended or terminated except
in writing and signed by both pal-ties. This agreement shall be governed by and
construed under the laws of the State of New York without regard to principles
of conflicts of laws thereof and the parties agree to submit themselves to the
jurisdiction of the courts located in the State and County of New York, which
shall be the sole tribunals in which any party may institute and maintain a
legal proceeding against the other party arising from any dispute hereunder.

consummation of the transactions contemplated hereby will, directly or
indirectly, with or without the giving of notice or lapse of time, or both: (i)
violate any provisions of the Certificate of Incorporation or By-laws of the
Company; or (ii) violate, or be in conflict with, or constitute a default under,
any agreement, lease, mortgage, debt or obligation of the Company or require the
payment, any prepayment or other penalty with respect thereto. The Company has
all requisite power and authority to enter into and perform its obligations
under this letter and to issue and deliver the Warrants. The execution and
delivery of this letter and the Warrants and the consummation by it of the
