any and all loss, liability claim, damage and expense whatsoever (including, but
not limited to, any and all expenses reasonably incurred in investigating,
preparing or defending against any litigation commenced or threatened, or any
claim whatsoever) arising out of any untrue statement or alleged untrue
statement of a material fact contained in the Offering Materials (as from time
to time amended and supplemented) or the omission or alleged omission therefrom
of a material fact required to be stated therein or necessary to make the
statements therein not misleading; provided, however, that the Issuer shall not
be liable in any such case to the extent that any such loss, claim, damage, or
liability arises out of or is based upon an indemnified party's gross
negligence, bad faith, willful misconduct, an untrue statement, or alleged
untrue statement or omission or alleged omission made in the Offering Materials,

                                       5
<PAGE>

or such amendment or supplement, in reliance upon and in conformity with written
information furnished to the Issuer by any such indemnified party specifically
for use in the preparation thereof.

                   (b) The Issuer will indemnify and hold harmless the
Broker-Dealer and its affiliates, as defined under the Exchange Act, and each of
their officers, directors, employees, agents and representatives against any
civil lawsuits, civil claims, civil damages or civil liabilities, to which the
Broker-Dealer and its affiliates, as defined under the Exchange Act, and each of
their officers, directors, employees, agents and representatives may become
subject under Section 15 of the Exchange Act, or otherwise, insofar as such
civil losses, civil claims, civil damages or civil liabilities (or actions in
respect thereof) arise out of or are based upon any direct sale of the
Securities to investors by the Issuer with no involvement by the Broker-Dealer
or any other indemnified party.

The foregoing indemnification agreement shall extend upon the same terms and
conditions to, and shall inure to the benefit of, each person, if any, who
controls the Broker-Dealer or its affiliates within the meaning of the
Securities Act.

                   (c) The Broker-Dealer agrees that it will indemnify, defend
and hold harmless the Issuer and its affiliates and their respective officers,
directors, employees, and agents of any of the foregoing from and against any
loss, expense, claim, damage, or liability to which they may become subject
under any applicable securities law or otherwise (including but not limited to
any and all expense reasonably incurred in investigating, preparing or defending
against any litigation, connected or threatened, or any claim whatsoever),
insofar as any such loss, expense, claim, damage or liability (or actions in
respect thereof) arises out of or is based on the actual or alleged unlawful
sale by the Broker-Dealer of securities or an indemnified party's gross
negligence, bad faith, willful misconduct or any untrue statement or alleged
untrue statement of any material fact made by the Broker-Dealer other than in
reliance upon and consistent with the Offering Materials or other written
information furnished to the Issuer by any such indemnified party specifically
for use in the preparation thereof.

creating a relationship of Issuer, any of its officers, directors, employees or
agents, any affiliates of any of the foregoing, or other selling agents.

         9. TERMINATION.

         This Agreement may be terminated by either the Issuer or the
