            2.2 Partial Exercise. Subject to the provisions hereof, this Warrant
may be  exercised  in part by surrender of this Warrant in the manner and at the
place  provided in subsection  2.1 except that the amount  payable by the holder

number of  shares  of Common  Stock  (without  giving  effect to any  adjustment
therein)  designated by the holder in the  subscription at the end hereof by (b)

will forthwith issue and deliver to or upon the order of the holder hereof a new
Warrant or Warrants of like tenor,  in the name of the holder  hereof or as such
holder  (upon  payment  by such  holder of any  applicable  transfer  taxes) may
request, calling in the aggregate on the face or faces thereof for the number of

which  such  holder  shall  continue  to be  entitled  after  such  exercise  in
accordance  with the  provisions of this Warrant  provided that if the holder of
this Warrant shall fail to make any such request,  such failure shall not affect
the continuing obligation of the Company to afford such holder any such rights.

practicable  after the exercise of this  Warrant in full or in part,  and in any
event within 10 days thereafter the Company at it expense (including the payment
by it of any applicable  issue taxes) will cause to be issued in the name of and
delivered to the holder  hereof,  or as such holder (upon payment by such holder
of any applicable  transfer taxes) may direct, a certificate or certificates for
the  number of full  paid and  non-assesable  shares  of Common  Stock (or Other
Securities) to which such holder shall be entitled upon such exercise,  plus, in
lieu of any  fractional  share to which such holder would  otherwise be entitled
cash equal to such fraction  multiplied by the then current  market value of one
full share,  together  with any other  stock or other  securities  and  property
(including  cash where  applicable)  to which such holder is entitled  upon such
exercise pursuant to section 4 or otherwise.

         4.  Adjustment  for Dividends in Other Stock,  etc.,  Reclassification,

            (d) then, and in each such case the holder of this Warrant, upon the
exercise  hereof as  provided  in section 2, shall be  entitled  to receive  the
amount of stock and other  securities and property  (including cash in the cases
referred  to in  subdivisions  (b) and (c) of this section 4) which such  holder
would hold on the date of such  exercise  if on the  Original  Issue Date he had
been the holder of record of the number of shares of Common  Stock called for on
the face of this Warrant and had thereafter, during the period from the Original
Issue Date to and including the date of such exercise,  retained such shares and
all such other or additional  (or less) stock and other  securities and property

securities  and property  (including  cash) to which such holder would have been
entitled upon such consummation or in connection with such  dissolution,  as the
case may be, if such holder had so  exercised  this  Warrant  immediately  prior
thereto,  all subject to further adjustment  thereafter as provided in section 4
and 6 hereof.
