exercise of the Warrant,  upon the request of the holder hereof  acknowledge  in
writing its  continuing  obligation to afford to such holder any rights to which
such holder shall continue to be entitled after such exercise in accordance with
the  provisions  of this  Warrant.  If the  holder  shall  fail to make any such

to afford to such holder any such rights.

                                       2

          1.4  Trustee for  Warrant  Holders.  In the event that a bank or trust
company  shall have been  appointed  as trustee  for the  holders of the Warrant
pursuant to Subsection 3.2, such bank or trust company shall have all the powers

its own name for the account of the Company or such  successor  person as may be
entitled  thereto,  all  amounts  otherwise  payable  to  the  Company  or  such
successor,  as the case may be, on  exercise  of this  Warrant  pursuant to this
Section 1.

     2. Procedure for Exercise.

          2.1 Delivery of Stock  Certificates,  Etc.,  on Exercise.  The Company
agrees that the shares of Common Stock  purchased  upon exercise of this Warrant
shall be deemed to be issued to the Holder as the record owner of such shares as
of the close of  business  on the date on which  this  Warrant  shall  have been
surrendered and payment made for such shares in accordance herewith.  As soon as
practicable  after the exercise of this  Warrant in full or in part,  and in any
event  within  three (3) business  days  thereafter,  the Company at its 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,  or as such  Holder  (upon
payment  by  such  Holder  of any  applicable  transfer  taxes)  may  direct  in
compliance with applicable  securities  laws, a certificate or certificates  for
the number of duly and validly issued,  fully paid and  nonassessable  shares of
Common  Stock (or Other  Securities)  to which such Holder  shall be entitled on
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 Fair
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 1 or otherwise.

          2.2  Exercise.  Payment may be made either (i) in cash or by certified
or  official  bank  check  payable  to the  order  of the  Company  equal to the
applicable  aggregate Exercise Price, (ii) by delivery of the Warrant, or shares
of Common Stock and/or Common Stock  receivable  upon exercise of the Warrant in
accordance  with the formula set forth below in this  Section 2.2, or (iii) by a
combination  of any of the  foregoing  methods,  for the number of Common Shares
specified in such Exercise  Notice (as such exercise number shall be adjusted to
reflect any adjustment in the total number of shares of Common Stock issuable to
the Holder per the terms of this  Warrant)  and the Holder  shall  thereupon  be
entitled to receive the number of duly  authorized,  validly issued,  fully-paid
and  non-assessable  shares of Common Stock (or Other Securities)  determined as
provided herein.  Notwithstanding any provisions herein to the contrary,  if the
Fair  Market  Value of one share of Common  Stock is greater  than the  Exercise
Price (at the date of  calculation  as set forth  below),  in lieu of exercising
this Warrant for cash, the Holder may elect to receive shares equal to the value
(as determined  below) of this Warrant (or the portion thereof being  exercised)
by  surrender of this Warrant at the  principal  office of the Company  together
with the  properly  endorsed  Exercise  Notice in which event the Company  shall
issue to the  Holder a number  of  shares of  Common  Stock  computed  using the
following formula:

     X=Y            (A-B)
                   ---------
                      A

     Where X =   the number of shares of Common Stock to be issued to the Holder

                                       3

     Y          = the number of shares of Common Stock purchasable
                under the Warrant or, if only a portion of the
                Warrant is being exercised, the portion of the
                Warrant being exercised (at the date of such
                calculation)

     A =        the Fair Market  Value of one share of the  Company's
                Common Stock (at the date of such calculation)

     B =        Exercise Price (as adjusted to the date of such calculation)

     3. Effect of Reorganization, Etc.; Adjustment of Exercise Price.

          3.1 Reorganization, Consolidation, Merger, Etc. In case at any time or
from  time  to  time,  the  Company  shall  (a)  effect  a  reorganization,  (b)
consolidate  with or  merge  into  any  other  person,  or (c)  transfer  all or
substantially all of its properties or assets to any other person under any plan
or arrangement  contemplating the dissolution of the Company, then, in each such
case,  as a condition  to the  consummation  of such a  transaction,  proper and
adequate  provision  shall be made by the  Company  whereby  the  Holder of this
Warrant,  on the exercise  hereof as provided in Section 1 at any time after the
consummation of such  reorganization,  consolidation  or merger or the effective
date of such  dissolution,  as the case may be,  shall  receive,  in lieu of the
Common  Stock (or Other  Securities)  issuable  on such  exercise  prior to such
consummation or such effective date, the stock and other 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.

          3.2  Dissolution.  In the  event  of any  dissolution  of the  Company
following the transfer of all or substantially  all of its properties or assets,
the Company,  concurrently with any distributions  made to holders of its Common
Stock,  shall at its expense  deliver or cause to be delivered to the Holder the
stock and other  securities  and property  (including  cash,  where  applicable)
receivable  by the Holder of the  Warrant  pursuant to Section  3.1,  or, if the
Holder shall so instruct the Company,  to a bank or trust  company  specified by
the Holder and having its  principal  office in New York,  NY as trustee for the
Holder of the Warrant (the "Trustee").

          3.3  Continuation of Terms.  Upon any  reorganization,  consolidation,
merger or transfer (and any dissolution  following any transfer)  referred to in
this  Section 3, this  Warrant  shall  continue in full force and effect and the
terms hereof shall be applicable to the shares of stock and other securities and
property  receivable on the exercise of this Warrant after the  consummation  of
such   reorganization,   consolidation  or  merger  or  the  effective  date  of
dissolution  following  any such  transfer,  as the case  may be,  and  shall be
binding upon the issuer of any such stock or other securities, including, in the
case of any such transfer,  the person acquiring all or substantially all of the
properties  or assets of the  Company,  whether  or not such  person  shall have
expressly  assumed  the terms of this  Warrant as  provided in Section 4. In the
event  this  Warrant  does not  continue  in full  force  and  effect  after the
consummation of the transactions described in this Section 3, then the Company's
securities and property  (including  cash, where  applicable)  receivable by the
Holders  of  the  Warrant  will  be  delivered  to  Holder  or  the  Trustee  as
contemplated by Section 3.2.

                                       4

     4.  Extraordinary  Events  Regarding  Common  Stock.  In the event that the
Company shall (a) issue  additional  shares of the Common Stock as a dividend or
other  distribution on outstanding  Common Stock,  (b) subdivide its outstanding
shares of Common  Stock,  or (c)  combine its  outstanding  shares of the Common
Stock into a smaller  number of shares of the Common  Stock,  then, in each such
event,  the Exercise  Price  shall,  simultaneously  with the  happening of such
event,  be adjusted by multiplying  the then Exercise  Price by a fraction,  the
numerator  of which  shall be the number of shares of Common  Stock  outstanding
immediately prior to such event and the denominator of which shall be the number
of shares of Common  Stock  outstanding  immediately  after such event,  and the
product so obtained shall  thereafter be the Exercise Price then in effect.  The
Exercise Price, as so adjusted,  shall be readjusted in the same manner upon the
happening of any successive  event or events described herein in this Section 4.
The  number of shares of Common  Stock  that the  holder of this  Warrant  shall
thereafter,  on the  exercise  hereof as  provided  in Section 1, be entitled to
receive shall be adjusted to a number  determined by  multiplying  the number of
shares of Common  Stock that would  otherwise  (but for the  provisions  of this
Section 4) be issuable on such exercise by a fraction of which (a) the numerator
is the  Exercise  Price that would  otherwise  (but for the  provisions  of this
Section 4) be in effect, and (b) the denominator is the Exercise Price in effect
on the date of such exercise.

     5.  Certificate  as to  Adjustments.  In  each  case of any  adjustment  or
readjustment in the shares of Common Stock (or Other Securities) issuable on the
exercise of the  Warrant,  the Company at its expense  will  promptly  cause its
Chief Financial Officer or other appropriate designee to compute such adjustment
or  readjustment  in  accordance  with the terms of the  Warrant  and  prepare a
certificate  setting forth such adjustment or readjustment and showing in detail
the facts upon which such  adjustment  or  readjustment  is based,  including  a
statement of (a) the consideration received or receivable by the Company for any
additional shares of Common Stock (or Other Securities) issued or sold or deemed
to have been issued or sold,  (b) the number of shares of Common Stock (or Other
Securities) outstanding or deemed to be outstanding,  and (c) the Exercise Price
and the number of shares of Common  Stock to be received  upon  exercise of this
Warrant,  in effect  immediately prior to such adjustment or readjustment and as
adjusted or readjusted as provided in this Warrant.  The Company will  forthwith
mail a copy of each  such  certificate  to the  holder  of the  Warrant  and any
Warrant agent of the Company (appointed pursuant to Section 11 hereof).

     6. Reservation of Stock, Etc., Issuable on Exercise of Warrant. The Company
will at all times reserve and keep  available,  solely for issuance and delivery
on the  exercise of the Warrant,  shares of Common  Stock (or Other  Securities)
from time to time issuable on the exercise of the Warrant.

     7. Assignment;  Exchange of Warrant.  Subject to compliance with applicable
securities  laws,  this  Warrant,  and  the  rights  evidenced  hereby,  may  be
transferred  by any  registered  holder hereof (a  "Transferor")  in whole or in
part.  On the  surrender  for exchange of this  Warrant,  with the  Transferor's
endorsement  in  the  form  of  Exhibit  B  attached  hereto  (the   "Transferor
Endorsement  Form") and together with evidence  reasonably  satisfactory  to the
Company  demonstrating  compliance with applicable  securities laws, which shall
include,  without  limitation,  the  provision  of  a  legal  opinion  from  the
Transferor's  counsel (at the  Company's  expense)  that such transfer is exempt
from the  registration  requirements  of applicable  securities  laws,  and with
payment by the  Transferor  of any  applicable  transfer  taxes)  will issue and
deliver  to or on the  order of the  Transferor  thereof a new  Warrant  of like

                                       5

tenor, in the name of the Transferor and/or the transferee(s)  specified in such
Transferor  Endorsement Form (each a "Transferee"),  calling in the aggregate on
the face or faces thereof for the number of shares of Common Stock called for on
the face or faces of the Warrant so surrendered by the Transferor.

     8. Replacement of Warrant. On receipt of evidence  reasonably  satisfactory
to the Company of the loss,  theft,  destruction  or  mutilation of this Warrant
and, in the case of any such loss,  theft or  destruction  of this  Warrant,  on
delivery of an indemnity agreement or security  reasonably  satisfactory in form
and amount to the Company or, in the case of any such  mutilation,  on surrender
and  cancellation  of this Warrant,  the Company at its expense will execute and
deliver, in lieu thereof, a new Warrant of like tenor.

     9. Registration Rights. The Holder of this Warrant has been granted certain
registration rights by the Company. These registration rights are set forth in a
Registration Rights Agreement entered into by the Company and Holder dated as of
even date of this Warrant.

     10.  Maximum  Exercise.  The Holder shall not be entitled to exercise  this
Warrant on an exercise date, in connection  with that number of shares of Common
Stock  which would be in excess of the sum of (i) the number of shares of Common
Stock  beneficially  owned by the Holder and its affiliates on an exercise date,
and (ii) the number of shares of Common Stock issuable upon the exercise of this
Warrant with respect to which the determination of this proviso is being made on
an exercise date,  which would result in beneficial  ownership by the Holder and
its affiliates of more than 4.99% of the  outstanding  shares of Common Stock of
the Company on such date.  For the  purposes  of the proviso to the  immediately
preceding sentence,  beneficial ownership shall be determined in accordance with
Section 13(d) of the Securities Exchange Act of 1934, as amended, and Regulation
13d-3 thereunder.  Notwithstanding the foregoing,  the restriction  described in
this  paragraph  may be revoked upon 75 days prior notice from the Holder to the
Company and is  automatically  null and void upon an Event of Default  under the
Note made by the  Company  to the  Holder  dated the date  hereof  (as  amended,
modified or supplemented from time to time, the "Note").

     11. Warrant Agent. The Company may, by written notice to the each Holder of
the Warrant,  appoint an agent for the purpose of issuing Common Stock (or Other
Securities)  on the exercise of this Warrant  pursuant to Section 1,  exchanging
this  Warrant  pursuant to Section 7, and  replacing  this  Warrant  pursuant to
Section 8, or any of the foregoing,  and thereafter any such issuance,  exchange
or replacement, as the case may be, shall be made at such office by such agent.

     12. Transfer on the Company's  Books.  Until this Warrant is transferred on
the books of the Company,  the Company may treat the registered holder hereof as
the absolute  owner hereof for all purposes,  notwithstanding  any notice to the
contrary.

                                       6

     13. Notices,  Etc. All notices and other communications from the Company to
the  Holder  of this  Warrant  shall be  mailed  by first  class  registered  or
certified mail,  postage prepaid,  at such address as may have been furnished to
the Company in writing by such Holder or, until any such Holder furnishes to the
Company an  address,  then to, and at the  address  of, the last  Holder of this
Warrant who has so furnished an address to the Company.

     14. Miscellaneous. This Warrant and any term hereof may be changed, waived,
discharged  or terminated  only by an instrument in writing  signed by the party
against which  enforcement of such change,  waiver,  discharge or termination is
sought.  This Warrant shall be governed by and construed in accordance  with the
laws of State of New York without regard to principles of conflicts of laws. Any
action brought concerning the transactions contemplated by this Warrant shall be
brought only in the state courts of New York or in the federal courts located in
the state of New York;  provided,  however,  that the Holder may choose to waive
this  provision  and  bring  an  action  outside  the  state  of New  York.  The
individuals  executing  this Warrant on behalf of the Company agree to submit to
the  jurisdiction  of such courts and waive trial by jury. The prevailing  party
shall be entitled to recover from the other party its reasonable attorney's fees
and  costs.  In the event  that any  provision  of this  Warrant  is  invalid or
unenforceable  under any applicable  statute or rule of law, then such provision
shall be deemed  inoperative  to the extent that it may conflict  therewith  and
shall be deemed  modified to conform  with such statute or rule of law. Any such
provision  which  may prove  invalid  or  unenforceable  under any law shall not
affect the validity or  enforceability  of any other  provision of this Warrant.
The headings in this Warrant are for purposes of reference  only,  and shall not
limit  or  otherwise  affect  any  of  the  terms  hereof.   The  invalidity  or
unenforceability  of any provision hereof shall in no way affect the validity or
enforceability  of any other provision  hereof.  The Company  acknowledges  that
legal counsel  participated in the  preparation of this Warrant and,  therefore,
stipulates  that the rule of  construction  that  ambiguities are to be resolved
against the drafting  party shall not be applied in the  interpretation  of this
Warrant to favor any party against the other party.
