qualifying or registering the Representative's Warrants, Representative's Shares

qualify  as a  foreign  corporation  to do  business  under the laws of any such
jurisdiction.

Unit Warrant,  Representative's  Warrants and Representative's Shares to be sold

and each person,  if any, who controls the Company within the meaning of Section
15 of the Act or Section  20(a) of the Exchange  Act,  against all loss,  claim,
damage or expense or liability  (including all expenses  reasonably  incurred in
investigating,  preparing or defending  against any claim  whatsoever)  to which
they may become  subject under the Act, the Exchange Act or  otherwise,  arising
from information furnished by or on behalf of such Holders, or their

warranties  and  covenants  of  the  Company  to or  for  the  benefit  of  such
Representative(s)  shall also be made to and for the  benefit  of such  Holders.

or  agreements  with the  Company  or the  Representative(s)  except as they may

Common Stock  issuable upon the exercise of each  Representative's  Unit Warrant
shall be increased in proportion to such increase in outstanding  shares. In the
event that the number of shares of Common  Stock  outstanding  is decreased by a
combination of the outstanding  Common Stock, then, from and after the effective
time of such  decrease  by reason of such  combination,  the number of shares of
Common Stock  issuable upon the exercise of each  Representative's  Unit Warrant
shall be decreased in proportion to such decrease in the  outstanding  shares of
Common Stock.

         (b)  In  case  of  any  reorganization  or   reclassification   of  the
outstanding Common Stock (other than a change in par value, or from par value to

to purchase the kind and amount of shares of Common  Stock and other  securities
and   property   receivable   upon   such   reorganization,    reclassification,
consolidation, merger, sale or conveyance by a holder of the number of shares of
Common Stock which the Holder of such  Representative's  Unit Warrant shall then

changes occurring between the date of this Agreement and the date of exercise of
such Representative's Unit Warrant.

         (c) Subject to the  provisions  of this  Section 8, in case the Company
shall, at any time prior to the exercise of the Warrants,  make any distribution
of its  assets  to  holders  its  Common  Stock as a  liquidating  or a  partial
liquidating  dividend,  then the holder of Warrants who  exercises  its Warrants
after the record date for the  determination  of those  holders of Common  Stock
entitled to such distribution of assets as a liquidating or partial  liquidating
dividend  shall be  entitled  to  receive  for the  Warrant  Exercise  Price per
Warrant,  in  addition  to each  share  of  Common  Stock,  the  amount  of such
distribution  or, at the option of the Company,  a sum equal to the value of any
such  assets  at the time of such  distribution  as  determined  by the Board of
Directors  of the Company in good faith)  which would have been  payable to such
holder had such holder been the holder of record of the Common Stock  receivable
upon exercise of its Warrant on the record date for the  determination  of those
entitled to such distribution.

         (d) In  case  of the  dissolution,  liquidation  or  winding  up of the
Company, all rights under this Representative's Unit Warrants shall terminate on
a date fixed by the Company, such date to be no earlier than ten (10) days prior
to the  effectiveness  of such  dissolution,  liquidation  or winding up and not
later than five (5) days prior to such effectiveness. Notice of such termination
of  purchase  rights  shall  be  given  to the  last  registered  holder  of the
Representative's  Unit  Warrants,  as the same shall  appear on the books of the
Company maintained by the Warrant Agent, by registered mail at least thirty (30)
days prior to such termination date.

         (e) In case the Company  shall,  at any time prior to the expiration of
the Representative's  Unit Warrants and prior to the exercise thereof,  offer to
the holders of its Common Stock any rights to subscribe for additional shares of
any class of the Company,  then the Company shall give written notice thereof to
the  registered  holders of the  Representative's  Unit  Warrants  not less than
thirty  (30) days prior to the date on which the books of the Company are closed
or a record date is fixed for the determination of the stockholders  entitled to
such  subscription  rights.  Such notice shall  specify the date as to which the
books shall be closed or the

                                       9

of subscription shall terminate if the  Representative's  Unit Warrant shall not
be  exercised  on or before the date of such closing of the books or such record
date.

         (f) Any adjustment pursuant to the aforesaid provisions of this Section
8 shall be made on the basis of the number of shares of Common  Stock  which the
holder  thereof  would have been  entitled to acquire  upon the  exercise of the
Representative's Unit Warrant immediately prior to the event giving rise to such
adjustment.

Representative's   Unit  Warrant  is  exchangeable  without  expense,  upon  the
surrender thereof by the registered Holder at the principal  executive office of
the  Company,  for a new  Representative's  Unit  Warrant of like tenor and date
representing  in the  aggregate  the  right  to  purchase  the  same  number  of
Representative's  shares  and  Representative's  Warrants  as  provided  in  the
original  Representative's  Unit  Warrant  in such  denominations  as  shall  be

         10.  ELIMINATION  OF  FRACTIONAL  INTERESTS.  The Company  shall not be
required to issue certificates representing fractions of Representative's Shares
upon the exercise of the Representative's Unit Warrant, nor shall it be required

of the parties that all fractional interests shall be eliminated by rounding any
fraction  up to the  nearest  whole  number of  shares of Common  Stock or other
securities, properties or rights.

         11.  RESERVATION  AND LISTING OF  SECURITIES.  The Company shall at all

Unit  Warrant  and  Representative's  Warrants,  such number of shares of Common
Stock or other  securities,  properties  or rights as shall be issuable upon the
exercise thereof. The Company covenants and agrees that, upon exercise of the

                                       10

the Exercise Price therefor,  all  Representative's  Shares and other securities
issuable  upon such  exercise  shall be duly and  validly  issued,  fully  paid,
non-assessable  and not subject to the preemptive rights of any stockholder.  As
long as the Representative's Unit Warrant and/or Representative's Warrants shall
be   outstanding,   the  Company  shall  use  its  best  efforts  to  cause  all
Representative's  Shares and Representative's  Shares issuable upon the exercise
of the  Representative's  Warrants to be listed  (subject to official  notice of
issuance)  on all  securities  exchanges  on which the Common  Stock may then be
listed and/or quoted on the Nasdaq Stock Market.

         12. NOTICES TO REPRESENTATIVE'S UNIT WARRANT HOLDERS. Nothing contained
in this Agreement shall be construed as conferring upon the Holders the right to

meetings of stockholders  for the election of directors or any other matter,  or
any rights whatsoever as a stockholder of the Company.  If, however, at any time
