or alleged  untrue  statement of a material  fact  contained in (a) Section 4 of
this  Agreement,  (b) the Offering  Materials  (except those written  statements
relating to the  Placement  Agent  given by the  Placement  Agent for  inclusion
therein),  (c) any  application  or  other  document  or  written  communication
executed  by the  Company or based upon  written  information  furnished  by the
Company filed in any jurisdiction in order to qualify the Common Stock under the

omission or alleged omission from documents described in clauses (a), (b) or (c)
above of a material fact required to be stated  therein or necessary to make the

warranty,  covenant  or  agreement  made by the Company in this  Agreement.  The
Company further agrees that upon demand by an indemnified person, at any time or
from time to time, it will promptly  reimburse such  indemnified  person for any
loss, claim, damage,  liability, cost or expense actually and reasonably paid by
the  indemnified  person as to which the  Company  has  indemnified  such person
pursuant  hereto.  Notwithstanding  the foregoing  provisions of this  Paragraph
7(A),  any such  payment or  reimbursement  by the Company of fees,  expenses or
disbursements  incurred by an  indemnified  person in any  proceeding in which a
final  judgment by a court of competent  jurisdiction  (after all appeals or the
expiration  of time to appeal) is entered  against the  Placement  Agent or such
indemnified  person based upon specific finding of fact that the Placement Agent
or such  indemnified  person's gross  negligence or willful  misfeasance will be
promptly repaid to the Company.

                  (ii) The Placement  Agent hereby agrees that it will indemnify
and hold the  Company  and each  officer,  director,  shareholder,  employee  or
representative  of the Company,  and each person  controlling,  controlled by or
under common  control  with the Company  within the meaning of Section 15 of the
Securities  Act or Section 20 of the Exchange Act or the Rules and  Regulations,
harmless from and 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 deposition) to which the Company or such indemnified person
of the Company may become  subject under the  Securities  Act, the Exchange 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 material breach of
any representation,  warranty, covenant or agreement made by the Placement Agent
in this Agreement,  or (ii) any false or misleading  information provided to the
Company  in  writing  by  one  of  the  Placement  Agent's  indemnified  persons

                  (iii) The Investor  hereby  agrees that it will  indemnify and
hold the Placement Agent and each officer,  director,  shareholder,  employee or
representative of the Placement Agent, and each person  controlling,  controlled
by or under  common  control  with the  Placement  Agent  within the  meaning of
Section 15 of the  Securities Act or Section 20 of the Exchange Act or the Rules
and  Regulations,  harmless  from and 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 deposition) to which the Placement Agent or such
indemnified  person  of  the  Placement  Agent  may  become  subject  under  the
Securities  Act,  the  Exchange  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  Investor  or its  officers,  employees  or
representatives  in its  acting  as the  Investor  for the  Offering,  (ii)  the
material breach of any representation,  warranty,  covenant or agreement made by
the  Investor  in the  Offering  Materials,  or (iii)  any  false or  misleading
information provided to the Placement Agent by one of the Investor's indemnified
persons.

                  (iv) The Placement  Agent hereby agrees that it will indemnify
and hold the  Investor  and each  officer,  director,  shareholder,  employee or
representative of the Investor,  and each person  controlling,  controlled by or
under common  control with the Investor  within the meaning of Section 15 of the
Securities  Act or Section 20 of the Exchange Act or the Rules and  Regulations,
harmless from and 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  deposition)  to which the  Investor  or such  indemnified
person of the Investor may become subject under the Securities Act, the Exchange
Act, the Rules and Regulations, or any other federal or state law or regulation,
common law or otherwise, arising out of or based upon the material breach of any
representation,  warranty,  covenant or agreement made by the Placement Agent in
this Agreement.

                  (v) 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),


                                       10
<PAGE>


(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.

                  (vi) 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 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
Securities  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 Securities Act or Section 20
of the  Exchange  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.

<PAGE>


                  (vii) 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.

                  (viii)  The  Company  hereby  waives,  to the  fullest  extent
permitted by law, any right to or claim of any punitive, exemplary,  incidental,
indirect,   special,   consequential  or  other  damages   (including,   without
limitation,  loss of profits)  against  the  Placement  Agent and each  officer,
director,  shareholder,  employee or  representative  of the placement agent and
each  person  controlling,  controlled  by or  under  common  control  with  the
Placement  Agent  within the  meaning of  Section  15 of the  Securities  Act or
Section 20 of the Exchange Act or the Rules and  Regulations  arising out of any
cause whatsoever  (whether such cause be based in contract,  negligence,  strict
liability,  other tort or otherwise).  Notwithstanding  anything to the contrary
contained  herein,  the  aggregate  liability  of the  Placement  Agent and each
officer,  director,  shareholder,  employee or  representative  of the Placement
Agent and each person  controlling,  controlled by or under common  control with
the Placement  Agent within the meaning of Section 15 of the  Securities  Act or
Section 20 of the Exchange Act or the Rules and Regulations shall not exceed the
compensation  received by the Placement Agent pursuant to Section 2 hereof. This
limitation of liability shall apply  regardless of the cause of action,  whether
contract, tort (including, without limitation,  negligence) or breach of statute
or any other legal or equitable obligation.

      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.

                  (i) The Closing  shall be held at the offices of the  Investor
or its counsel.  The  obligations  of the  Placement  Agent  hereunder  shall be
subject to the continuing  accuracy of the representations and warranties of the
Company  and the  Investor  herein as of the date  hereof  and as of the Date of
Closing (the "Closing Date") with respect to the Company or the Investor, as the

on and as of the Closing Date of the  statements  of the officers of the Company
made pursuant to the provisions  hereof;  and the performance by the Company and

the date  thereof,  which  opinion  shall be in form  and  substance  reasonably
satisfactory to the Investor, their counsel and the Placement Agent.
