against any and all loss, claim, damage, liability, cost or expense whatsoever
(including, but not limited to, any and all reasonable legal fees and other
expenses and disbursements incurred in connection with investigating, preparing
to defend or defending any action, suit or proceeding, including any inquiry or
investigation, commenced or threatened, or any claim whatsoever or in appearing
or preparing for appearance as a witness in any action, suit or proceeding,
including any inquiry, investigation or pretrial proceeding such as a


                                       9
<PAGE>

deposition) to which the Investor or such indemnified person of the Investor may
become subject under the 1933 Act, the 1934 Act, the Rules and Regulations, or
any other federal or state law or regulation, common law or otherwise, arising
out of or based upon (i) the conduct of the Placement Agent or its officers,
employees or representatives in its acting as the Placement Agent for the
Offering or (ii) the material breach of any representation, warranty, covenant
or agreement made by the Placement Agent in this Agreement (iii) any false or
misleading information provided to the Investor by one of the Placement Agent's
indemnified persons.

           E. Promptly after receipt by an indemnified party of notice of
commencement of any action covered by Section 7(A), (B), (C) or (D), the party
to be indemnified shall, within five (5) business days, notify the indemnifying
party of the commencement thereof; the omission by one (1) indemnified party to
so notify the indemnifying party shall not relieve the indemnifying party of its
obligation to indemnify any other indemnified party that has given such notice
and shall not relieve the indemnifying party of any liability outside of this
indemnification if not materially prejudiced thereby. In the event that any
action is brought against the indemnified party, the indemnifying party will be
entitled to participate therein and, to the extent it may desire, to assume and
control the defense thereof with counsel chosen by it which is reasonably
acceptable to the indemnified party. After notice from the indemnifying party to
such indemnified party of its election to so assume the defense thereof, the
indemnifying party will not be liable to such indemnified party under such
Section 7(A), (B), (C), or (D) for any legal or other expenses subsequently
incurred by such indemnified party in connection with the defense thereof, but
the indemnified party may, at its own expense, participate in such defense by
counsel chosen by it, without, however, impairing the indemnifying party's
control of the defense. Subject to the proviso of this sentence and
notwithstanding any other statement to the contrary contained herein, the
indemnified party or parties shall have the right to choose its or their own
counsel and control the defense of any action, all at the expense of the
indemnifying party if, (i) the employment of such counsel shall have been
authorized in writing by the indemnifying party in connection with the defense
of such action at the expense of the indemnifying party, or (ii) the
indemnifying party shall not have employed counsel reasonably satisfactory to
such indemnified party to have charge of the defense of such action within a
reasonable time after notice of commencement of the action, or (iii) such
indemnified party or parties shall have reasonably concluded that there may be
defenses available to it or them which are different from or additional to those
available to one or all of the indemnifying parties (in which case the
indemnifying parties shall not have the right to direct the defense of such
action on behalf of the indemnified party or parties), in any of which events
such fees and expenses of one additional counsel shall be borne by the
indemnifying party; provided, however, that the indemnifying party shall not, in
connection with any one action or separate but substantially similar or related
actions in the same jurisdiction arising out of the same general allegations or
circumstance, be liable for the reasonable fees and expenses of more than one
separate firm of attorneys at any time for all such indemnified parties. No
settlement of any action or proceeding against an indemnified party shall be
made without the consent of the indemnifying party.

           F. In order to provide for just and equitable contribution in
circumstances in which the indemnification provided for in Section 7(A) or 7(B)
is due in accordance with its terms but is for any reason held by a court to be
unavailable on grounds of policy or otherwise, the Company and the Placement
Agent shall contribute to the aggregate losses, claims, damages and liabilities
(including legal or other expenses reasonably incurred in connection with the
investigation or defense of same) which the other may incur in such proportion
so that the Placement Agent shall be responsible for such percent of the


                                       10
<PAGE>

aggregate of such losses, claims, damages and liabilities as shall equal the
percentage of the gross proceeds paid to the Placement Agent and the Company
shall be responsible for the balance; provided, however, that no person guilty
of fraudulent misrepresentation within the meaning of Section 11(f) of the 1933
Act shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. For purposes of this Section 7(F), any person
controlling, controlled by or under common control with the Placement Agent, or
any partner, director, officer, employee, representative or any agent of any
thereof, shall have the same rights to contribution as the Placement Agent and
each person controlling, controlled by or under common control with the Company
within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act
and each officer of the Company and each director of the Company shall have the
same rights to contribution as the Company. Any party entitled to contribution
will, promptly after receipt of notice of commencement of any action, suit or
proceeding against such party in respect of which a claim for contribution may
be made against the other party under this Section 7(D), notify such party from
whom contribution may be sought, but the omission to so notify such party shall
not relieve the party from whom contribution may be sought from any obligation
they may have hereunder or otherwise if the party from whom contribution may be
sought is not materially prejudiced thereby. The indemnity and contribution
agreements contained in this Section 7 shall remain operative and in full force
and effect regardless of any investigation made by or on behalf of any
indemnified person or any termination of this Agreement.

           8. PAYMENT OF EXPENSES.

           The Company hereby agrees to bear all of the expenses in connection
with the Offering, including, but not limited to the following: filing fees,
printing and duplicating costs, advertisements, postage and mailing expenses
with respect to the transmission of Offering Materials, registrar and transfer
agent fees, escrow agent fees and expenses, fees of the Company's counsel and
accountants, issue and transfer taxes, if any.

           9. CONDITIONS OF CLOSING.

           B. At or prior to the Closing, the Placement Agent shall have been

accuracy, completeness or satisfaction of any of the representations, warranties
or conditions herein contained.

                                       11
<PAGE>

           C. At and prior to the Closing, (i) there shall have been no material
adverse change nor development involving a prospective change in the condition
or prospects or the business activities, financial or otherwise, of the Company
from the latest dates as of which such condition is set forth in the Offering
Materials; (ii) there shall have been no transaction, not in the ordinary course
of business except the transactions pursuant to the Securities Purchase
Agreement entered into by the Company which has not been disclosed in the

provision of any instrument relating to any outstanding indebtedness for which a
waiver or extension has not been otherwise received; (iv) except as set forth in
the Offering Materials, the Company shall not have issued any securities (other
than those to be issued as provided in the Offering Materials) or declared or
paid any dividend or made any distribution of its capital stock of any class and
there shall not have been any change in the indebtedness (long or short term) or
liabilities or obligations of the Company (contingent or otherwise) and trade
payable debt; (v) no material amount of the assets of the Company shall have
been pledged or mortgaged, except as indicated in the Offering Materials; and
(v) no action, suit or proceeding, at law or in equity, against the Company or
affecting any of its properties or businesses shall be pending or threatened
before or by any court or federal or state commission, board or other
administrative agency, domestic or foreign, wherein an unfavorable decision,
ruling or finding could materially adversely affect the businesses, prospects or
financial condition or income of the Company, except as set forth in the
Offering Materials.

           D. At Closing, the Placement Agent shall receive a certificate of the
Company signed by an executive officer and chief financial officer, dated as of
the applicable Closing, to the effect that the conditions set forth in
subparagraph (C) above have been satisfied and that, as of the applicable
closing, the representations and warranties of the Company set forth herein are
true and correct.

           10. TERMINATION.

           This Agreement shall be co-terminus with, and terminate upon the same
terms and conditions as those set forth in, the Equity Line of Credit Agreement.
The rights of the Investor and the obligations of the Company under the
Registration Rights Agreement, and the rights of the Placement Agent and the
obligations of the Company shall survive the termination of this Agreement
unabridged.
