Company shall have the sole and absolute discretion to accept or not accept the
terms of any Transaction. Neither the Company nor any of its affiliates shall

effect on the financial condition of the Company. The Company represents and

extent that the Securities are placed in a private placement, or an appropriate
subscription agreement, to the extent that the securities to be placed have been
publicly registered ("Materials") will be true and accurate in all material
respects and will not contain any untrue statement of a material fact or omit to
state a material fact necessary in order to make the statements therein not
misleading in light of the circumstances under which such statements are made.

diligence" investigation and will be using and relying upon the information
supplied by the Company and its officers, agents and others, the Materials, and
any other publicly available information concerning the Company.

or more agreements (the "Warrant Agreements") in form and substance reasonably
satisfactory to AGENT and the Company. The Warrant Agreements shall contain
customary terms consistent with the registration rights granted to the
Investors.

                                   Schedule A

                           INDEMNIFICATION PROVISIONS

Ladies and Gentlemen:

         In connection with our engagement of Olympus Securities, LLC ("AGENT")
as a Finder, we hereby agree to indemnify and hold harmless AGENT and its
affiliates, and the respective directors, officers, shareholders, agents and
employees of AGENT (collectively the "Indemnified Persons"), from and against
any and all claims, actions, suits, proceedings (including those of
shareholders), damages, liabilities and expenses as incurred by any of them
(including the reasonable fees and expenses of counsel) which (A) relate to or
arise out of (i) any actions taken or omitted to be taken (including any untrue
statements made to any Indemnified Person in connection with our engagement of
AGENT, or (B) otherwise relate to or arise out of AGENT's activities on our
behalf under AGENT's engagement, including any action by AGENT to collect
amounts owed to it in connection therewith, and we shall reimburse any
Indemnified Person for all expenses (including the reasonable fees and expenses
of counsel) as incurred by such Indemnified Person in connection with
investigating, preparing or defending any such claim, action , suit or
proceeding (collectively a "Claim"), in connection with pending or threatened
litigation in which any Indemnified Person is a party. We will not, however, be
responsible for any Claim, which is finally judicially determined to have
resulted exclusively from the gross negligence or willful misconduct of any
person seeking indemnification hereunder. We further agree that no Indemnified
Person shall have any liability to us for or in connection with our engagement
of AGENT except for any Claim incurred by us solely as a direct result of any
Indemnified Person's gross negligence or willful misconduct.

         We further agree that we will not, without the prior written consent of
AGENT, settle, compromise or consent to the entry of any judgment in any pending
or threatened Claim in respect of which indemnification may be reasonably sought
hereunder (whether or not any Indemnified Person is an actual or potential party
to such Claim), unless such settlement, compromise or consent includes an
unconditional, irrevocable release of each Indemnified Person against whom such
claim may be brought hereunder from any and all liability arising out of such
claim.

         Promptly upon receipt by an Indemnified Person of notice of any
complaint or the assertion or institution of any Claim with respect to which
indemnification is being sought hereunder, such Indemnified Person shall notify
us in writing of such complaint or of such assertion or institution but failure
to do so notify us shall not relieve us from any obligations we may have
hereunder, unless and only to the extent such failure results in the forfeiture
by us of substantial rights and defenses, and will not in any event relieve us
from any other obligation or liability we may have to any Indemnified Person, we
will assume the defense of such Claim, including the employment of counsel
reasonably satisfactory to such Indemnified Person and the payment of reasonable
fees and expenses of such counsel. In the event, however, that such Indemnified
Person reasonably determines that having common counsel with the Company and/or
another Indemnified Person would present such counsel with a conflict of
interest or if the defendant in, or target of, any such Claim, includes an
Indemnified Person and us, and such Indemnified reasonably concludes that there
may be legal defenses available to it or other Indemnified Persons different
from or in addition to those available to us, then such Indemnified Person may
employ its own separate counsel to represent or defend it in any such Claim and
we shall pay the reasonable fees and expenses of such counsel. Notwithstanding
anything herein to the contrary, if we fail timely or diligently to defend,
contest, or otherwise protect against any Claim, the relevant Indemnified Person
shall have the right, but not the obligation, to defend, contest, compromise,
settle, assert cross claims, or counterclaims or otherwise protect against the
same, and shall be fully indemnified by us therefore, including without
limitation, for the reasonable fees and expenses of its counsel and all amounts
paid as a result of such Claim or the compromise or settlement thereof. In any
Claim in which we assume the defense, the Indemnified Person shall have the
right to participate in such Claim and to retain its own counsel therefore at
its own expense.

         We agree that if any indemnity sought by an Indemnified Person
hereunder is held by a court to be unavailable for any reason, then (whether or
not AGENT is the Indemnified Person), we and AGENT shall contribute to the Claim


                                        5
<PAGE>
for which such indemnify is held unavailable in such proportion as is
appropriate to reflect the relative benefits to us, on the one hand, and AGENT
on the other, in connection with AGENT's engagement referred to above, and the
relative fault, as between us and the Indemnified Person in respect of the
Claim, subject to the limitation that in no event shall the amount of AGENT's
contribution to such Claim exceed the amount of fees actually received by AGENT
from us pursuant to AGENT's engagement. We hereby agree that the relative
benefits to us, on the one hand, and AGENT on the other, with respect to AGENT's
engagement shall be deemed to be in the same proportion as (a) the total value
paid or proposed to be paid or received by us or our stockholders as the case
may be, pursuant to the transaction (whether or not consummated) for which you
are engaged to render services bears to (b) the fee actually paid to AGENT in
connection with such engagement; provided, however, that under no circumstances
whatsoever shall AGENT be required to contribute to any such claim any amount in
excess of the fee actually paid in connection with such engagement.

         Our indemnity, reimbursement and contribution obligations under this
Agreement shall be in addition to, and shall in no way limit or otherwise
adversely affect, any rights that any Indemnified Party may have at law or at
equity.

         Should AGENT or its personnel be required or requested by us to provide
documentary evidence or testimony in connection with any proceeding arising form
or relating to AGENT's engagement, we agree to pay all reasonable expenses
(including fees incurred for legal counsel) in complying therewith.

         We hereby consent to personal junction and service of process and venue
in any court in the State of New York in which any claim for indemnity is
brought by and Indemnified Person.

         It is understood that, in connection with AGENT's engagement, AGENT may
be engaged to act in one or more additional capacities and that the terms of the
original engagement or any such additional engagement may be embodied in one or
more separate written agreements. The provisions of this Agreement shall apply
to the original engagement, any such additional engagement and any modifications
of the original engagement or such additional engagement and shall remain in
full force and effect following the completion or termination of AGENT's
engagement(s).


                                            Very truly yours,
