                        WARRANT TO PURCHASE COMMON STOCK

Warrant No. __                                  Number of Shares:  650,000
                                                (subject to adjustment)
Date of Issuance:  May 14, 2004

HEMISPHERX  BIOPHARMA,  INC., a Delaware  corporation  (the  "Company"),  hereby
certifies  that,  for Ten  United  States  Dollars  ($10.00)  and other good and
valuable  consideration  including,  without  limitation,  the Holder's  current
exercise of warrants to purchase  500,000  shares of Common  Stock (as  defined)
with an expiration  date of June 25, 2008, the receipt and  sufficiency of which
are hereby  acknowledged  (provided,  however,  that the holders of the Warrants
shall  withhold  from  the  exercise  price  of the  foregoing  warrants  in the
aggregate  (x)  $84,000 to pay the fees of the  placement  agent  engaged by the
Company in connection with the  transactions  contemplated  hereby and (y) 7,500
for the  holders'  reasonable,  documented  fees and expenses  (including  legal
expenses)  incurred in  connection  with the  consummation  of the  transactions
contemplated  hereby),  , the registered holder hereof or its permitted assigns,
is entitled,  subject to the terms and conditions  set forth below,  to purchase
from the Company  upon  surrender  of this  Warrant,  at any time or times on or
after  November 14, 2004,  but not after 11:59 P.M.,  New York City Time, on the
Expiration Date (as defined herein) 650,000 fully paid  nonassessable  shares of
Common Stock (as defined  herein) of the Company at the Warrant  Exercise  Price
per share provided in Section 1(b) below.  Notwithstanding  the  foregoing,  the
Company  shall not effect the  exercise  of this  Warrant  and no holder of this
Warrant  shall have the right to exercise  this Warrant to the extent that after
giving  effect to such  exercise,  such  Person  (together  with  such  Person's
affiliates), would have acquired, through exercise of this Warrant or otherwise,
beneficial  ownership of a number of shares of Common Stock that,  when added to
the number of shares of Common Stock beneficially owned by such Person (together
with such Person's affiliates),  exceeds 4.99% of the number of shares of Common
Stock outstanding immediately after giving effect to such exercise. For purposes
of the  foregoing  sentence,  the  aggregate  number of  shares of Common  Stock
beneficially owned by such Person and its affiliates shall include the number of
shares of Common Stock  issuable  upon  exercise of this Warrant with respect to
which the determination of such sentence is being made, but shall exclude shares
of Common  Stock  which would be issuable  upon (i)  exercise of the  remaining,
unexercised  portion of this Warrant  beneficially  owned by such Person and its
affiliates  and (ii) exercise or conversion of the  unexercised  or  unconverted
portion of any other securities of the Company beneficially owned by such Person
and its  affiliates  (including,  without  limitation,  any  convertible  notes,
debentures or preferred stock) subject to a limitation on conversion or exercise
analogous  to the  limitation  contained  herein.  Except  as set  forth  in the
preceding sentence,  for purposes of this paragraph,  beneficial ownership shall
be calculated in accordance with Section 13(d) of the Securities Exchange Act of
1934,  as amended.  Upon the written  request of any holder,  the Company  shall
promptly, but in no event later than two (2) Business Days following the receipt
of such  notice,  confirm in writing to any such  holder the number of shares of
Common Stock then outstanding.  In any case, the number of outstanding shares of
Common Stock shall be determined after giving effect to the exercise of Warrants
(as defined below) by such holder and its affiliates  since the date as of which
such number of outstanding shares of Common Stock was last reported.

Section 1.

a. REGISTRATION  RIGHTS AGREEMENT.  This Warrant (as defined herein) is one of a
series of  Warrants  issued on the date  hereof.  The  Company  agrees  that the
Warrant Shares (as defined herein) shall be treated as "Registrable  Securities"
in  accordance   with,  and  shall  be  governed  by,  identical  terms  to  the
Registration  Rights Agreement,  dated as of January 26, 2004 (as such agreement
may be amended from time to time, the "Registration  Rights Agreement"),  by and
among the Company and the buyers named therein (including the holder), as if the
Company and the holder hereof had executed such Registration Rights Agreement on
the Original Issuance Date; provided, however, that:

(1) Section 2(a) thereof  shall not apply and instead the Company  agrees to the
following:

         The Company  shall use its  reasonable  best  efforts to file within 60
         days of the Original  Issuance Date (but in no event later than 90 days
         following  the  Original  Issuance  Date)  (such date being the "Filing
         Deadline") with the SEC the Registration Statement on Form S-3 covering
         the resale of all of the Registrable Securities. In the event that Form
         S-3 is unavailable for such a registration,  the Company shall use such
         other  form as is  available  for such a  registration,  subject to the
         provisions of Section 2(d) of the  Registration  Rights  Agreement,  in
         which case the "Filing Deadline" shall be one hundred twenty (120) days
         after the Original  Issuance Date.  The  Registration  Statement  shall
         register  for resale at least  1,755,000  shares of Common  Stock (with
         respect to all of the Warrants in the aggregate), subject to adjustment
         as provided in Section 2(e) of the Registration  Rights Agreement.  The
         Company shall use its reasonable best efforts to have the  Registration
         Statement declared effective by the SEC as soon as practicable,  but in
         no event later than the date which is sixty (60) days after the date on
         which the  Registration  Statement is filed (the "Filing Date").  Until
         such time as the  Registration  Statement is declared  effective by the
         SEC,  the  Company  shall not file with the SEC any other  registration
         statement  under the 1933 Act with  respect  to the  resale or  initial
         issuance of any Company securities; and

(2)   Section 2(f) thereof shall not apply; and

(3) The first  sentence of Section  3(a) shall not apply and instead the Company
shall  promptly  prepare  and file with the SEC a  Registration  Statement  with
respect to the Registrable Securities (but in no event later than the applicable
Filing Deadline) and use its best efforts to cause such  Registration  Statement
relating to the Registrable  Securities required to be covered thereby to become
effective as soon as  practicable  after such filing (but in no event later than
the date which is sixty (60) days after the Filing Date).


For  purposes  of clarity,  the  issuance of this  Warrant is  unrelated  to the
transaction  pursuant to which the  Registration  Rights  Agreement  was entered
into.

stock dividend, stock split or other similar transaction during such period) and

value as mutually  determined  by the  Company  and the holders of the  Warrants
representing at least 60% of the shares of Common Stock obtainable upon exercise
of the Warrants issued on the Original  Issuance Date then  outstanding.  If the

Section 2.        EXERCISE OF WARRANT.

a. Subject to the terms and conditions hereof,  this Warrant may be exercised by
the holder hereof then  registered  on the books of the Company,  in whole or in
part, at any time on any Business Day on or after the opening of business on the
date hereof and prior to 5:00 P.M., New York City Time, on the  Expiration  Date
by (i)  delivery of a written  notice,  in the form of the  subscription  notice
attached as EXHIBIT A hereto or a reasonable  facsimile  thereof (the  "Exercise
Notice"),  to the  Company  and the  Company's  designated  transfer  agent (the
"Transfer  Agent"),  of such holder's  election to exercise this Warrant,  which
notice  shall  specify  the number of Warrant  Shares to be  purchased,  (ii)(A)
payment  to the  Company  of an  amount  equal  to the  Warrant  Exercise  Price
multiplied  by the  number of Warrant  Shares as to which this  Warrant is being
exercised (the  "Aggregate  Exercise  Price") in cash or delivery of a certified
check or bank draft  payable to the order of the  Company  or wire  transfer  of
immediately available funds or (B) by notifying the Company that this Warrant is
being  exercised  pursuant to a Cashless  Exercise (as defined in Section 2(e)),
and (iii) the  surrender of this Warrant or a copy of this Warrant  (provided it
is accompanied by an indemnification undertaking with respect to this Warrant in
the case of its loss,  theft or  destruction)  to a common carrier for overnight
delivery to the Company or by  delivery of a facsimile  copy of this  Warrant to
the Company as soon as practicable  following such date; provided,  that if such
Warrant  Shares are to be issued in any name  other than that of the  registered
holder  of this  Warrant,  such  issuance  shall be  deemed a  transfer  and the
provisions of Section 7 shall be applicable. In the event of any exercise of the
rights  represented  by this Warrant in compliance  with this Section 2(a),  the
Company  shall on the second (2nd)  Business Day (the  "Warrant  Share  Delivery
Date") following the date of its receipt of the Exercise  Notice,  the Aggregate
Exercise  Price (or notice of Cashless  Exercise)  and the original or a copy of
this Warrant  (provided it is accompanied by an  indemnification  undertaking or
other form of security  reasonably  satisfactory  to the Company with respect to
this Warrant in the case of its loss, theft or destruction)  (collectively,  the
"Exercise  Delivery  Documents"),  (A) in the  case of a public  resale  of such
Warrant  Shares in accordance  with the provisions of the  Irrevocable  Transfer
Agent  Instructions,  provided  the  Transfer  Agent  is  participating  in  The
Depository Trust Company ("DTC") Fast Automated Securities Transfer Program and,
if required by DTC,  the holder  provides a customary  representation  letter to
DTC, at the holder's  request,  credit such aggregate number of shares of Common
Stock to which the holder  shall be entitled to the  holder's or its  designee's
balance account with DTC through its Deposit  Withdrawal Agent Commission system
or (B) issue and deliver to the address as specified in the Exercise  Notice,  a
certificate or  certificates  in such  denominations  as may be requested by the
holder  in the  Exercise  Notice,  registered  in the name of the  holder or its
designee,  for the number of shares of Common Stock to which the holder shall be
entitled upon such exercise.  Upon delivery of the Exercise Delivery  Documents,
the holder of this Warrant  shall be deemed for all  corporate  purposes to have
become the holder of record of the  Warrant  Shares  with  respect to which this
Warrant has been exercised, irrespective of the date of delivery of this Warrant
as required by clause (iii) above or the  certificates  evidencing  such Warrant
Shares. In the case of a dispute as to the determination of the Warrant Exercise
Price, the Closing Sale Price of a security or the arithmetic calculation of the
number of Warrant  Shares,  the Company shall  promptly  issue to the holder the
number of shares of Common  Stock  that is not  disputed  and shall  submit  the
disputed  determinations or arithmetic  calculations to the holder via facsimile
within two (2) Business Days of receipt of the holder's  Exercise Notice. If the
holder and the Company are unable to agree upon the determination of the Warrant
Exercise Price,  the Closing Sale Price or arithmetic  calculation of the number
of Warrant Shares within one (1) Business Day of such disputed  determination or
arithmetic  calculation  being  submitted to the holder,  then the Company shall
immediately  submit via facsimile (i) the disputed  determination of the Warrant
Exercise Price or the Closing Sale Price to an independent, reputable investment
banking firm selected jointly by the Company and the holder or (ii) the disputed
arithmetic  calculation  of the  number of  Warrant  Shares to its  independent,
outside  accountant.  The Company shall cause the investment banking firm or the
accountant,  as the case may be, to perform the  determinations  or calculations
and notify  the  Company  and the  holder of the  results no later than ten (10)
Business  Days  from  the  time  it  receives  the  disputed  determinations  or
calculations.  Such investment  banking firm's or accountant's  determination or
calculation,  as the case may be,  shall be deemed  conclusive  absent  manifest
error.

b. Unless the rights  represented  by this  Warrant  shall have expired or shall
have  been  fully  exercised  (without  regard  to any  limitation  on  exercise
hereunder),  the Company shall,  as soon as practicable  using  reasonable  best
efforts and in no event later than five (5)  Business  Days after its receipt of
the Exercise  Delivery  Documents (the "Warrant  Delivery  Date") and at its own
expense, issue a new Warrant identical in all respects to this Warrant exercised
except it shall  represent  rights to  purchase  the  number of  Warrant  Shares
purchasable (without regard to any limitation on exercise hereunder) immediately
prior to such  exercise  under this Warrant,  less the number of Warrant  Shares
with respect to which such Warrant is exercised.

c. No  fractional  shares of Common  Stock are to be issued upon the exercise of
this  Warrant,  but  rather  the number of shares of Common  Stock  issued  upon
exercise  of this  Warrant  shall be  rounded  up or down to the  nearest  whole
number.

d. If the  Company  shall  fail for any  reason or for no reason to issue to the
holder  within  five (5)  Business  Days of  receipt  of the  Exercise  Delivery
Documents,  a certificate  for the number of shares of Common Stock to which the
holder is entitled or to credit the  holder's  designee's  balance  account with
DTC, in  accordance  with Section 2 hereof,  for such number of shares of Common
Stock to which  the  holder  is  entitled  upon the  holder's  exercise  of this
Warrant, the Company shall, in addition to any other remedies under this Warrant
or otherwise available to such holder, pay as additional damages in cash to such
holder on each day after the Warrant  Share  Delivery  Date such exercise is not
timely effected in an amount equal to 0.05% multiplied by the product of (I) the
sum of the number of shares of Common Stock not issued to the holder on or prior
to the Warrant Share  Delivery  Date and to which such holder is entitled  under
the  holder's  Exercise  Notice and (II) the excess of the Closing Sale Price of
the Common Stock on the Warrant Share  Delivery  Date over the Warrant  Exercise
Price then in effect.  The foregoing  notwithstanding,  the damages set forth in
this Section 2(d) shall be stayed with respect to the number of shares of Common
Stock for which there is a good faith  dispute being  resolved  pursuant to, and
within the time periods provided for in, Section 2(a), pending the resolution of
such dispute.

e.  Notwithstanding  anything  contained herein to the contrary,  if at any time
during  the two (2)  Business  Day period  immediately  preceding  the  holder's
delivery of an Exercise  Notice,  a  Registration  Statement  (as defined in the
Registration  Rights Agreement) covering the Warrant Shares that are the subject
of the Exercise Notice (the  "Unavailable  Warrant Shares") is not available for
the resale of such Unavailable  Warrant Shares,  the holder of this Warrant may,
at its election  exercised in its sole  discretion,  exercise this Warrant as to
any or all of such  Unavailable  Warrant  Shares and, in lieu of making the cash
payment  otherwise  contemplated to be made to the Company upon such exercise in
payment of the  Aggregate  Exercise  Price,  elect  instead to receive upon such
exercise the "Net Number" of shares of Common Stock determined  according to the
following formula (a "Cashless Exercise"):


                  Net Number = (A x B) - (A x C)
                                    ---------------------
                                            B

                  For purposes of the foregoing formula:

                           A= the total  number of shares with  respect to which
                           this Warrant is then being exercised.

                           B= the Closing  Sale Price of the Common Stock on the
                           trading  day  immediately  preceding  the date of the
                           Exercise Notice.

                           C= the Warrant  Exercise Price then in effect for the
                           applicable   Warrant  Shares  at  the  time  of  such
                           exercise.

as follows:

a. This Warrant is, and any Warrants issued in  substitution  for or replacement
of this Warrant will upon issuance be, duly authorized and validly issued.

on exercise hereunder)and the par value of said shares will at all times be less
than or equal to the applicable Warrant Exercise Price.

d. The Company shall  promptly  secure the listing of the shares of Common Stock
issuable  upon  exercise of this Warrant  (without  regard to any  limitation on
exercise   hereunder)  upon  each  national  securities  exchange  or  automated
quotation  system,  if any,  upon which  shares of Common  Stock are then listed
(subject to official notice of issuance upon exercise of this Warrant) and shall
maintain,  so long as any other shares of Common Stock shall be so listed,  such
listing  of all  shares of Common  Stock  from  time to time  issuable  upon the
exercise  of  this  Warrant  (without  regard  to  any  limitation  on  exercise
hereunder);  and the Company shall so list on each national  securities exchange
or  automated  quotation  system,  as the case may be, and shall  maintain  such
listing of, any other shares of capital  stock of the Company  issuable upon the
exercise  of  this  Warrant  (without  regard  to  any  limitation  on  exercise
hereunder)  if and so long as any  shares of the same  class  shall be listed on
such national securities exchange or automated quotation system.

e. The Company  will not, by  amendment  of its  Articles  of  Incorporation  or
through  any  reorganization,   transfer  of  assets,   consolidation,   merger,
dissolution,  issue or sale of securities,  or any other voluntary action, avoid
or seek to  avoid  the  observance  or  performance  of any of the  terms  to be
observed or performed by it hereunder.  Without  limiting the  generality of the
foregoing,  the  Company  (i) will not  increase  the par value of any shares of
Common Stock  receivable  upon the  exercise of this  Warrant  above the Warrant
Exercise  Price  then in  effect,  (ii)  will  take all such  actions  as may be
necessary or appropriate in order that the Company may validly and legally issue
fully paid and  nonassessable  shares of Common  Stock upon the exercise of this
Warrant and (iii) will not take any action which  results in any  adjustment  of
the  Warrant  Exercise  Price if the total  number  of  shares  of Common  Stock
issuable  after the action upon the exercise of all of the Warrants would exceed
the total  number of shares of Common  Stock then  authorized  by the  Company's
Articles  of  Incorporation  and  available  for the  purpose of issue upon such
exercise.

f. This  Warrant will be binding  upon any entity  succeeding  to the Company by
merger,  consolidation  or  acquisition  of  all  or  substantially  all  of the
Company's assets.

g.  Any  recapitalization,   reorganization,  reclassification,   consolidation,
merger,  sale of all or  substantially  all of the  Company's  assets to another
Person or other  transaction,  in each case which is effected in such a way that
holders of Common  Stock are  entitled  to  receive  securities  or assets  with
respect to or in exchange  for Common Stock is referred to herein as an "Organic
Change." Prior to the consummation of any (i) sale of all or  substantially  all
of the  Company's  assets to an  acquiring  Person,  (ii) other  Organic  Change
following  which the  Company is not a surviving  entity or (iii) other  Organic
Change  following  which the  Company is a  surviving  entity but the  Company's
stockholders no longer continue to own the publicly-traded stock of the Company,
the Company  will secure  from the Person  purchasing  such assets or the Person
issuing the  securities or providing the assets in such Organic  Change (in each
case,  the  "Acquiring  Entity")  a  written  agreement  (in form and  substance
reasonably  satisfactory  to the  holders of  Warrants  representing  at least a
majority of the shares of Common Stock  obtainable upon exercise of the Warrants
then outstanding  ("Majority Holders")) to deliver to the holder of this Warrant
in exchange for this Warrant,  a security of the Acquiring Entity evidenced by a
written instrument  substantially  similar in form and substance to this Warrant
and  reasonably  satisfactory  to the Majority  Holders  (including  an adjusted
exercise price equal to the value for the Common Stock reflected by the terms of
such consolidation,  merger or sale, and exercisable for a corresponding  number
of shares of Common  Stock  acquirable  and  receivable  upon  exercise  of this
Warrant (without regard to any limitations on the exercise of this Warrant),  if
the value so  reflected is less than the  Exercise  Price in effect  immediately
prior to such  consolidation,  merger or sale).  In the event that an  Acquiring
Entity is directly or indirectly  controlled by a company or entity whose common
stock or similar equity interest is listed, designated or quoted on a securities
exchange or trading  market,  the holder of this Warrant may elect to treat such
Person  as  the   Acquiring   Entity  for   purposes  of  this   Section   3(g).
Notwithstanding the foregoing, at the holder's option and request, the Acquiring
Entity shall, either (1) issue to such holder a new warrant substantially in the
form of this  Warrant  and  consistent  with the  foregoing  provisions,  or (2)
purchase  the  Warrant  from such holder for a purchase  price,  payable in cash
within five  Business  Days after such request (or, if later,  on the  effective
date of the Organic  Change),  equal to the Black Scholes value of the remaining
unexercised  portion of this Warrant on the date of such  request.  The terms of
any  agreement  pursuant to which an Organic  Change is effected  shall  include
terms  requiring  any such  successor  or  surviving  entity to comply  with the
provisions  of this  Section  3(g) and  insuring  that the Warrants (or any such
replacement security) will be similarly adjusted upon any subsequent transaction
analogous to an Organic Change.  Prior to the  consummation of any other Organic
Change,  the Company  shall make  appropriate  provision  (in form and substance
reasonably  satisfactory  to the  Majority  Holders)  to insure  that the holder
thereafter  will have the right to acquire and receive in lieu of or in addition
to (as the case may be) the  shares  of  Common  Stock  immediately  theretofore
acquirable and receivable  upon the exercise of this Warrant  (without regard to
any  limitations  on the  exercise  of this  Warrant),  such  shares  of  stock,
securities  or assets  that  would have been  issued or payable in such  Organic
Change with  respect to or in exchange  for the number of shares of Common Stock
which  would have been  acquirable  and  receivable  upon the  exercise  of this
Warrant as of the date of such Organic Change (without regard to any limitations
on the exercise of this Warrant).

                               Section 4. TAXES.

a. The Company  shall pay any and all  documentary,  stamp,  transfer  and other
similar  taxes which may be payable with respect to the issuance and delivery of
Warrant  Shares  upon  exercise of this  Warrant;  provided,  however,  that the
Company  shall not be  required to pay any tax that may be payable in respect of
any  transfer  involved  in the  issue  or  delivery  of  Common  Stock or other
securities  or  property in a name other than that of the  registered  holder of
this Warrant to be exercised  and such holder shall pay such amount,  if any, to
cover any applicable transfer or similar tax.

b. The Company and the Company's  transfer  agent shall be permitted to withhold
from any amounts payable to a registered holder of this Warrant or any holder of
Warrant Shares any taxes required by law to be withheld from such amounts.

c.   Notwithstanding  any  other  provision  of  this  Agreement  or  any  other
Transaction  Document,  any assignee or transferee  shall agree that the Company
and the Company's transfer agent shall be permitted to withhold from any amounts
payable to such assignee or transferee  any taxes required by law to be withheld
from such amounts.  Unless exempt from the obligation to do so, each assignee or
transferee  shall execute and deliver to the Company or the  Company's  transfer
agent, as applicable,  two properly completed and duly executed copies of either
(i) U.S.  Internal Revenue Service Form W-8BEN, or any successor form, (ii) U.S.
Internal Revenue Service Form W-8ECI, or any successor form, (iii) U.S. Internal
Revenue Service Form W-9, or any successor form, or (iv) other  applicable form,
certificate or document  prescribed by the U.S.  Internal  Revenue  Service,  as
applicable,  in each case,  indicating  that such  assignee or transferee is not
subject to "back-up  withholding"  for U.S.  Federal  income tax purposes.  Each
assignee  or  transferee  that  does not  deliver  such  forms  pursuant  to the
preceding sentence shall have the burden of proving to the Company's  reasonable
satisfaction  that it is exempt  from such  requirement  or the  Company and the
Company's  transfer agent shall be entitled to withhold as provided in the first
sentence  hereof.  In addition,  each assignee or  transferee  that is organized
under the laws of a jurisdiction other than the United States, any State thereof
or the District of Columbia (each, a "Non-U.S.  Assignee or  Transferee")  shall
deliver to the Company and the Company's  transfer  agent, to the extent legally
able to do so, with  respect to payments  of  dividends  by the Company for U.S.
Federal  income tax purposes,  if  applicable,  two properly  completed and duly
executed  copies  of  either  (i) U.S.  Internal  Revenue  Service  Form  W-8BEN
(claiming a reduction of U.S. Federal withholding tax under an applicable income
tax treaty,  if any), or any successor form, (ii) U.S.  Internal Revenue Service
Form W-8ECI  (claiming  complete  exemption from U.S.  Federal  withholding  tax
because the income is effectively  connected with a U.S. trade or business),  or
any successor  form, or (iii) other  applicable  form,  certificate  or document
prescribed by the U.S. Internal Revenue Service certifying as to such assignee's
or  transferee's  entitlement  to an  exemption  from,  or a reduction  of, U.S.
Federal withholding tax on payments of dividends by the Company for U.S. Federal
income tax purposes. Each Non-U.S.  Assignee or Transferee that does not deliver
a form or other  document  claiming  a  complete  exemption  from  U.S.  Federal
withholding  tax shall have the burden of  proving to the  Company's  reasonable
satisfaction  that it is completely  exempt from such tax or the Company and the
Company's transfer agent shall be entitled to withhold as provided in the second
sentence of this  Section  4(c).  The forms and other  documents  required to be
delivered  pursuant  to this  Section  4 shall be  properly  completed  and duly
executed and shall be delivered  on or prior to the date of such  assignment  or
transfer,  and from time to time  thereafter  if requested by the Company or the
Company's  transfer  agent.  In addition,  each  assignee and  transferee  shall
deliver  such  forms and  other  documents  promptly  upon the  obsolescence  or
invalidity  of any form or documents  previously  delivered by such  assignee or
transferee.  Each assignee and transferee  shall promptly notify the Company and
the Company's transfer agent at any time it determines that it is no longer in a
position to provide any previously  delivered  form,  document or certificate to
the  Company  and the  Company's  transfer  agent (or any form of  certification
adopted by the U.S. taxing authorities for such purpose).

Section  5.  WARRANT  HOLDER  NOT  DEEMED A  STOCKHOLDER.  Except  as  otherwise
specifically  provided  herein,  no holder,  as such,  of this Warrant  shall be
entitled to vote or receive  dividends  or be deemed the holder of shares of the
Company  for any  purpose,  nor shall  anything  contained  in this  Warrant  be
construed  to confer  upon the holder  hereof,  as such,  any of the rights of a
stockholder of the Company or any right to vote, give or withhold consent to any
corporate action (whether any reorganization,  issue of stock,  reclassification
of stock,  consolidation,  merger,  conveyance or otherwise),  receive notice of
meetings,  receive dividends or subscription rights, or otherwise,  prior to the
issuance to the holder of this  Warrant of the Warrant  Shares which he, she, or
it is then  entitled  to  receive  upon the due  exercise  of this  Warrant.  In
addition,  nothing  contained in this Warrant shall be construed as imposing any
liabilities  on such holder to purchase any  securities  (upon  exercise of this
Warrant  or  otherwise)  or  as a  stockholder  of  the  Company,  whether  such
liabilities are asserted by the Company or by creditors of the Company.

Section  6.  REPRESENTATIONS  OF  HOLDER.  The  holder of this  Warrant,  by the
acceptance  hereof,  represents  and warrants that it is acquiring this Warrant,
and the Warrant  Shares for its own account for  investment  only and not with a
view towards, or for sale in connection with, the public sale or distribution of
this  Warrant or the Warrant  Shares,  except  pursuant to sales  registered  or
exempted  under the  Securities  Act;  provided,  however,  that by  making  the
representations herein, the holder does not agree to hold this Warrant or any of
the Warrant Shares for any minimum or other specific term and reserves the right
to dispose of this Warrant and the Warrant Shares at any time in accordance with
or pursuant to a  registration  statement or an exemption  under the  Securities
Act. The holder of this Warrant further represents,  by acceptance hereof, that,
as of this date, such holder is an "accredited investor" as such term is defined
in Rule 501(a) of  Regulation  D  promulgated  by the  Securities  and  Exchange
Commission under the Securities Act (an "Accredited Investor").

                       Section 7. OWNERSHIP AND TRANSFER.

a. The Company shall maintain at its principal  executive offices (or such other
office or agency of the  Company  as it may  designate  by notice to the  holder
hereof), a register for this Warrant, in which the Company shall record the name
and address of the person in whose name this Warrant has been issued, as well as
the name and  address of each  transferee.  The  Company may treat the person in
whose name any  Warrant is  registered  on the  register as the owner and holder
thereof for all purposes, notwithstanding any notice to the contrary, but in all
events  recognizing  any  transfers  made in  accordance  with the terms of this
Warrant.

b. This Warrant and all rights hereunder shall be assignable and transferable by
the holder  hereof  without the consent of the Company  upon  surrender  of this
Warrant with a properly executed assignment (in the form of Exhibit B hereto) at
the principal  executive  offices of the Company (or such other office or agency
of the Company as it may designate in writing to the holder  hereof);  provided,
that (x) either (i) the Warrant shall have been registered  under the Securities
Act or (ii) the  Company  first  shall  have been  furnished  with an opinion of
counsel,  in a form reasonably  satisfactory to the Company,  to the effect that
such  sale or  transfer  is exempt  from the  registration  requirements  of the
Securities  Act and (y) such  transfer or  assignment  of this  Warrant does not
result in more than ten (10)  holders of all  outstanding  Warrants and any such
part or  portion  of this  Warrant  constitutes  at least  10% of the  number of
Warrant Shares  issuable upon exercise of all outstanding  Warrants  (subject to
appropriate   adjustment  for  stock  splits,  stock  dividends,   combinations,
recapitalizations  and other similar transactions) or such lesser number if such
transfer  involves all of the Warrant  Shares  represented  by the Warrants then
held by such transferor.

c. The Company is obligated to register the Warrant  Shares for resale under the
Securities  Act pursuant to the  Registration  Rights  Agreement.  The shares of
Common Stock issuable upon exercise of this Warrant shall constitute Registrable
Securities (as such term is defined in the Registration Rights Agreement).  Each
holder of this Warrant  shall be entitled to all of the  benefits  afforded to a
holder  of  any  such  Registrable  Securities  under  the  Registration  Rights
Agreement and such holder,  by its acceptance of this Warrant,  agrees and shall
agree  to be  bound  by and to  comply  with the  terms  and  conditions  of the
Registration  Rights  Agreement  applicable  to such  holder as a holder of such
Registrable Securities.

Section 8.  ADJUSTMENT  OF  WARRANT  EXERCISE  PRICE AND  NUMBER OF SHARES.  The
Warrant  Exercise  Price and the number of shares of Common Stock  issuable upon
exercise of this Warrant shall be adjusted from time to time as follows:

a. ADJUSTMENT OF WARRANT EXERCISE PRICE. If and whenever on or after the Warrant
Date and prior to the twelve (12) month  anniversary  of the Warrant  Date,  the
Company  issues or sells,  or is deemed to have  issued or sold,  any  shares of
Common Stock  (including the issuance or sale of shares of Common Stock owned or
held by or for the account of the Company,  but excluding shares of Common Stock
(i) issued or deemed to have been  issued by the Company in  connection  with an
Approved Stock Plan,  (ii) issued or deemed to have been issued upon exercise of
the  Warrants  or issued  upon the  issuance or  conversion  of the  Convertible
Debentures;  (iii)  issued upon  exercise of Options or  Convertible  Securities
which are  outstanding  on the date  immediately  preceding  the  Warrant  Date,
provided  that such  issuance  of shares of Common  Stock upon  exercise of such
Options or Convertible  Securities is made pursuant to the terms of such Options
or  Convertible  Securities  in effect  on the date  immediately  preceding  the
Warrant Date and such Options or  Convertible  Securities  are not amended after
the date  immediately  preceding  the  Warrant  Date other than with  respect to
Options  originally  issued  pursuant  to an Approved  Stock  Plan,  (iv) issued
pursuant to a Strategic  Financing;  or (v) issued to the public  pursuant to an
underwritten  offering  registered  pursuant to the  Securities  Act (but in all
events excluding  offerings pursuant to "equity lines" or similar products) ((i)
through (v) collectively,  "Excluded  Issuances")) for a consideration per share
(the "New  Issuance  Price")  less  than the  Warrant  Exercise  Price in effect
immediately  prior to such  issuance  or sale  (each  such sale or  issuance,  a
"Dilutive  Issuance"),  then  concurrent  with such issue or sale,  the  Warrant
Exercise  Price then in effect  shall be reduced to a price  (subject to Section
8(f)) equal to the New Issuance Price; provided, however, that in no event shall
the Warrant Exercise Price be less than $4.008 (subject to adjustments for stock
splits, stock dividends, stock combinations, reclassifications,  reorganizations
and  similar  events).  If and  whenever  on or  after  the  twelve  (12)  month
anniversary  of the Warrant Date and prior to the  Expiration  Date, the Company
issues or sells, or is deemed to have issued or sold, any shares of Common Stock
(including  the  issuance or sale of shares of Common  Stock owned or held by or
for the account of the Company,  but excluding  shares of Common Stock issued or
deemed to be issued pursuant to any Excluded  Issuance) in a Dilutive  Issuance,
then  concurrent  with such issue or sale,  the Warrant  Exercise  Price then in
effect  shall be reduced to a price  (rounded to the nearest  cent) equal to the
product of (x) the Warrant  Exercise Price in effect  immediately  prior to such
issuance or sale and (y) the quotient  determined by dividing (1) the sum of (I)
the  product  derived  by  multiplying  the  Warrant  Exercise  Price in  effect
immediately  prior to such  Dilutive  Issuance by the number of shares of Common
Stock Deemed Outstanding  immediately prior to such issue or sale, plus (II) the
consideration,  if any, received by the Company upon such Dilutive Issuance,  by
(2) the product  derived by  multiplying  the (I) the Warrant  Exercise Price in
effect  immediately prior to such Dilutive Issuance by (II) the number of shares
of Common Stock Deemed  Outstanding  immediately  after such Dilutive  Issuance;
provided,  however,  that in no event shall the Warrant  Exercise  Price be less
than $4.008 (subject to adjustments  for stock splits,  stock  dividends,  stock
combinations, reclassifications, reorganizations and similar events).

b.  EFFECT  ON  WARRANT  EXERCISE  PRICE OF  CERTAIN  EVENTS.  For  purposes  of
determining the adjusted  Warrant  Exercise Price under Section 8(a) above,  the
following shall be applicable:

(i) ISSUANCE OF OPTIONS. If the Company in any manner grants any Options and the
lowest price per share for which one share of Common Stock is issuable  upon the
exercise  of any such  Option or upon  conversion,  exchange  or exercise of any
Convertible  Securities  issuable  upon exercise of any such Option is less than
the  Warrant  Exercise  Price  in  effect  immediately  prior  to such  Dilutive
Issuance,  then such share of Common Stock shall be deemed to be outstanding and
to have been issued and sold by the Company at the time of the  granting or sale
of such Option for such price per share.  For purposes of this Section  8(b)(i),
the "lowest price per share for which one share of Common Stock is issuable upon
exercise  of any such  Option or upon  conversion,  exchange  or exercise of any
Convertible Securities issuable upon exercise of any such Option" shall be equal
to the  sum of  the  lowest  amounts  of  consideration  (if  any)  received  or
receivable by the Company with respect to any one share of Common Stock upon the
granting or sale of the Option, upon exercise of the Option and upon conversion,
exchange or exercise of any Convertible  Security issuable upon exercise of such
Option.  No further  adjustment of the Warrant Exercise Price shall be made upon
the actual issuance of such Common Stock or of such Convertible  Securities upon
the  exercise of such  Options or upon the actual  issuance of such Common Stock
upon conversion, exchange or exercise of such Convertible Securities.

(ii) ISSUANCE OF CONVERTIBLE SECURITIES.  If the Company in any manner issues or
sells any  Convertible  Securities  and the lowest price per share for which one
share of Common  Stock is issuable  upon such  conversion,  exchange or exercise
thereof is less than the Warrant Exercise Price in effect  immediately  prior to
such  Dilutive  Issuance,  then such share of Common Stock shall be deemed to be
outstanding  and to have been  issued and sold by the Company at the time of the
issuance or sale of such  Convertible  Securities for such price per share.  For
the purposes of this Section 8(b)(ii), the "lowest price per share for which one
share of Common Stock is issuable  upon such  conversion,  exchange or exercise"
shall  be equal  to the sum of the  lowest  amounts  of  consideration  (if any)
received or  receivable by the Company with respect to one share of Common Stock
upon the  issuance  or sale of the  Convertible  Security  and upon  conversion,
exchange or exercise of such Convertible  Security. No further adjustment of the
Warrant  Exercise  Price  shall be made upon the actual  issuance of such Common
Stock upon conversion,  exchange or exercise of such Convertible Securities, and
if any such issue or sale of such  Convertible  Securities is made upon exercise
of any Options for which  adjustment of the Warrant  Exercise  Price had been or
are to be made  pursuant to other  provisions  of this Section  8(b), no further
adjustment of the Warrant  Exercise  Price shall be made by reason of such issue
or sale.

(iii) CHANGE IN OPTION PRICE OR RATE OF CONVERSION.  If the purchase or exercise
price provided for in any Options, the additional consideration, if any, payable
upon the issue, conversion,  exchange or exercise of any Convertible Securities,
or the  rate  at  which  any  Convertible  Securities  are  convertible  into or
exchangeable  or  exercisable  for Common Stock changes at any time, the Warrant
Exercise  Price in effect at the time of such  change  shall be  adjusted to the
Warrant  Exercise  Price  which  would have been in effect at such time had such
Options or  Convertible  Securities  provided for such changed  purchase  price,
additional  consideration or changed conversion rate, as the case may be, at the
time initially granted,  issued or sold and the number of shares of Common Stock
acquirable hereunder shall be correspondingly  readjusted.  For purposes of this
Section 8(b)(iii),  if the terms of any Option or Convertible  Security that was
outstanding as of the date of issuance of this Warrant are changed in the manner
described in the immediately preceding sentence, then such Option or Convertible
Security and the Common  Stock  deemed  issuable  upon  conversion,  exchange or
exercise  thereof  shall be deemed  to have  been  issued as of the date of such
change.  No  adjustment  shall be made if such  adjustment  would  result  in an
increase of the Warrant Exercise Price then in effect.

c. HOLDER'S RIGHT OF ALTERNATIVE  WARRANT  EXERCISE PRICE FOLLOWING  ISSUANCE OF
CONVERTIBLE  SECURITIES.   If  the  Company  issues  or  sells  any  Options  or
Convertible  Securities  after the Original  Issuance Date that are  convertible
into or  exchangeable or exercisable for Common Stock at a price which varies or
may vary with the market price of the Common  Stock,  including by way of one or
more reset(s) to a fixed price (each of the formulations for such variable price
being herein  referred to as, the "Variable  Price"),  the Company shall provide
written notice thereof via facsimile and overnight courier to the holder of this
Warrant  (the  "Variable  Notice") on the date of  issuance of such  Convertible
Securities  or  Options.  From and after the date the  Company  issues  any such
Convertible Securities or Options with a Variable Price, but only for so long as
such Convertible  Securities or Options are  outstanding,  the holder shall have
the right,  but not the  obligation,  in its sole  discretion to substitute  the
Variable  Price for the Warrant  Exercise Price upon exercise of this Warrant by
designating in the Exercise Notice  delivered upon exercise of this Warrant that
solely for purposes of such exercise the holder is relying on the Variable Price
rather than the Warrant Exercise Price then in effect.  The holder's election to
rely on a Variable  Price for a particular  exercise of this  Warrant  shall not
obligate the holder to rely on a Variable Price for any future exercises of this
Warrant.

d.  EFFECT  ON  WARRANT  EXERCISE  PRICE OF  CERTAIN  EVENTS.  For  purposes  of
determining  the adjusted  Warrant  Exercise Price under Sections 8(a) and 8(b),
the following shall be applicable:

(i)  CALCULATION  OF  CONSIDERATION  RECEIVED.  In case any  Option is issued in
connection with the issue or sale of other  securities of the Company,  together
comprising one  integrated  transaction  in which no specific  consideration  is
allocated to such Options by the parties thereto,  then, solely for the purposes
of this  Section  8, the  Options  will be  deemed  to have  been  issued  for a
consideration of $0.01. If any Common Stock,  Options or Convertible  Securities
are  issued  or sold or  deemed  to have  been  issued  or sold  for  cash,  the
consideration  received  therefor will be deemed to be the gross amount received
by the Company therefor. If any Common Stock, Options or Convertible  Securities
are  issued or sold for a  consideration  other  than  cash,  the amount of such
consideration   received  by  the  Company  will  be  the  fair  value  of  such
consideration,   except  where  such   consideration   consists  of   marketable
securities,  in which case the amount of  consideration  received by the Company
will be the Closing Sale Price of such securities on the date of receipt of such
securities. If any Common Stock, Options or Convertible Securities are issued to
the owners of the  non-surviving  entity in connection  with any merger in which
the Company is the surviving entity,  the amount of consideration  therefor will
be deemed to be the fair value of such portion of the net assets and business of
the  non-surviving  entity as is attributable  to such Common Stock,  Options or
Convertible Securities,  as the case may be. The fair value of any consideration
other than cash or securities  will be determined by the Company and the holders
of Warrants  representing at least 60% of the shares of Common Stock  obtainable
upon  exercise  of all  Warrants  issued  on the  Original  Issuance  Date  then
outstanding.  If such parties are unable to reach agreement within ten (10) days
after the occurrence of an event requiring  valuation (the  "Valuation  Event"),
the fair value of such consideration will be determined within five (5) Business
Days after the tenth (10th) day following the Valuation Event by an independent,
reputable  appraiser  jointly  selected  by the  Company  and the holders of the
Warrants representing at least 60% of the shares of Common Stock obtainable upon
exercise of all Warrants issued on the Original  Issuance Date then outstanding.
The  determination of such appraiser shall be final and binding upon all parties
absent manifest error and the fees and expenses of such appraiser shall be borne
by the Company.

(ii) RECORD DATE.  If the Company  takes a record of the holders of Common Stock
for  the  purpose  of  entitling  them  (1)  to  receive  a  dividend  or  other
distribution  payable in Common Stock,  Options or in Convertible  Securities or
(2)  to  subscribe  for  or  purchase  Common  Stock,   Options  or  Convertible
Securities,  then such record date will be deemed to be the date of the issue or
sale of the shares of Common  Stock  deemed to have been issued or sold upon the
declaration  of such  dividend or the making of such other  distribution  or the
date of the granting of such right of subscription or purchase,  as the case may
be. If after the  occurrence  of such record date the  transaction  or event for
which such record date was set is abandoned or terminated,  then any adjustments
resulting  from this  Section  8(d)(ii)  as it  relates  to such  terminated  or
abandoned  transaction  or event  shall be  reversed  as if such record date had
never occurred.

e. ADJUSTMENT OF WARRANT EXERCISE PRICE AND NUMBER OF SHARES UPON SUBDIVISION OR
COMBINATION  OF  COMMON  STOCK.  If the  Company  at any time  after the date of
issuance  of this  Warrant  subdivides  (by any  stock  split,  stock  dividend,
recapitalization  or otherwise) one or more classes of its outstanding shares of
Common  Stock into a greater  number of shares,  the Warrant  Exercise  Price in
effect immediately prior to such subdivision will be proportionately reduced and
the number of shares of Common Stock  obtainable  upon  exercise of this Warrant
will be proportionately  increased. If the Company at any time after the date of
issuance  of this  Warrant  combines  (by  combination,  reverse  stock split or
otherwise) one or more classes of its outstanding  shares of Common Stock into a
smaller number of shares, the Warrant Exercise Price in effect immediately prior
to such combination will be  proportionately  increased and the number of shares
of Common Stock obtainable upon exercise of this Warrant will be proportionately
decreased.  Any adjustment under this Section 8(e) shall become effective at the
close of business on the date the subdivision or combination becomes effective.

f.  CERTAIN  EVENTS.  If any  event  occurs  of  the  type  contemplated  by the
provisions of this Section 8 in a private  transaction  (the primary  purpose of
which  is to  raise  equity  capital)  but not  expressly  provided  for by such
provisions  (including,  without limitation,  the granting of stock appreciation
rights,  phantom  stock rights or other rights with equity  features  other than
pursuant to an Excluded  Issuance),  then the Company's  Board of Directors will
make an appropriate  adjustment in the Warrant  Exercise Price and the number of
shares of Common Stock obtainable upon exercise of this Warrant so as to protect
the rights of the holders of the Warrants; provided that no such adjustment will
increase the Warrant  Exercise  Price or decrease the number of shares of Common
Stock obtainable as otherwise determined pursuant to this Section 8.

g.       NOTICES.

(i) Promptly following any adjustment of the Warrant Exercise Price, the Company
will give written notice thereof to the holder of this Warrant, setting forth in
reasonable  detail,  and  certifying,  the calculation of such  adjustment.  The
Company (at the Company's  expense),  if there shall be a disagreement among the
Company  and  holders  of  Warrants  representing  at least 60% of the shares of
Common Stock  obtainable  upon  exercise of all Warrants  issued on the Original
Issuance Date then outstanding,  shall retain  independent public accountants of
recognized  national  standing selected by the Board of Directors of the Company
to make any  computation  required in  connection  with  adjustments  under this
Warrant,  and a certificate  signed by such firm absent  manifest error shall be
conclusive  evidence  of the  correctness  of such  adjustment,  which  shall be
binding on the holder and the Company.

(ii) The Company will give written notice to the holder of this Warrant at least
ten (10) Business  Days prior to the date on which the Company  closes its books
or takes a record (A) with  respect to any  dividend  or  distribution  upon the
Common Stock, (B) with respect to any pro rata subscription  offer to holders of
Common Stock or (C) for  determining  rights to vote with respect to any Organic
Change,  dissolution or  liquidation,  provided that the Company need not in any
case provide such notice prior to the time such information is made known to the
public.

(iii) The Company will also give written notice to the holder of this Warrant at
least ten (10) Business Days prior to the date on which any Organic Change,  any
transaction  or  series of  transactions  in which  more than 50% of the  voting
securities of the Company are transferred to another Person,  or any dissolution
or liquidation  will take place,  provided that the Company need not in any case
provide  such  notice  prior to the time such  information  is made known to the
public.

h.  ADJUSTMENT.  No adjustment in the Warrant  Exercise  Price shall be required
unless such adjustment would require an increase or decrease of at least $.01 in
such price;  provided,  however,  that any  adjustments  which by reason of this
sentence  are not  required  to be made shall be carried  forward and taken into
account in any subsequent adjustment required to be made hereunder.

Section 9. LOST,  STOLEN,  MUTILATED  OR DESTROYED  WARRANT.  If this Warrant is
lost, stolen,  mutilated or destroyed, the Company shall promptly, on receipt of
an indemnification  undertaking or other form of security reasonably  acceptable
to the Company (or in the case of a mutilated Warrant, the Warrant), issue a new
Warrant  of like  denomination  and  tenor  as this  Warrant  so  lost,  stolen,
mutilated or destroyed.  Notwithstanding the foregoing,  if this Warrant is lost
by,  stolen from or destroyed by the original  holder  hereof,  the affidavit of
such original  holder  setting forth the  circumstances  of such loss,  theft or
destruction  shall  be  accepted  as  satisfactory   evidence  thereof,  and  no
indemnification  bond or other  security  shall be  required by the Company as a
condition to the  execution and delivery by the Company of a new Warrant to such
original holder other than such original holder's unsecured written agreement to
indemnify the Company  solely for losses  actually  incurred by the Company as a
direct consequence of the loss, theft or destruction of the Warrant.

Section 10.  NOTICE.  Any  notices,  consents,  waivers or other  communications
required or  permitted  to be given under the terms of this  Warrant  must be in
writing  and will be deemed  to have  been  delivered:  (i) upon  receipt,  when
delivered  personally;  (ii)  upon  receipt,  when sent by  facsimile  (provided

addressed  to the  party to  receive  the  same.  If notice is to be sent to the
Company,  the holder shall use its reasonable best efforts to provide additional
copies to the individuals listed below;  provided,  however, that the failure of
such  holder  to  send  such  additional  copies  shall  in  no  way  limit  the
effectiveness  of any  notice  sent to the  Company  to the  attention  of Chief

Section  11.  AMENDMENTS.  This  Warrant  and any term  hereof  may be  amended,
changed,  waived,  discharged,  or  terminated  only by an instrument in writing
signed  by the  party  or  holder  hereof  against  which  enforcement  of  such
amendment,  change,  waiver,  discharge  or  termination  is sought and shall be
binding  on such  party's  or  holder's  assignees  and  transferees;  provided,
however, that any such amendment,  change, waiver, discharge or termination that
adversely impacts the holders of any of the Warrants other than this Warrant may
be made only if the Company has obtained  the written  consent of the holders of
Warrants  representing  at least 60% of the shares of Common Stock issuable upon
exercise  of all of the  Warrants  issued  on the  Original  Issuance  Date then
outstanding;  provided,  further,  that no such action may  increase the Warrant
Exercise  Price or decrease the number of shares or class of stock issuable upon
exercise  of any  Warrants  without  the  written  consent of the holder of such
Warrant.  No waivers of any term,  condition or provision of this Warrant in any
one or more  instances  shall be  deemed  to be or  construed  as a  further  or
continuing waiver of any such term, condition or provision.

Section 12. DATE. The date of this Warrant is May 14, 2004 (the "Warrant Date").
This  Warrant,  in all events,  shall be wholly void and of no effect  after the
close of business on the Expiration Date, except that  notwithstanding any other
provisions  hereof,  the provisions of Section 7(c) shall continue in full force
and effect after such date as to any Warrant Shares or other  securities  issued
upon the exercise of this Warrant.

Section 13.  LIMITATION  ON NUMBER OF WARRANT  SHARES.  The Company shall not be
obligated to issue  Warrant  Shares upon  exercise of this Warrant to the extent
that the  issuance  of such  shares of Common  Stock  would cause the Company to
exceed  that  number of shares of Common  Stock which the Company may issue upon
exercise of this Warrant (the  "Exchange  Cap") without  breaching the Company's
obligations under the rules or regulations of the Principal Market,  except that
such  limitation  shall not  apply in the event  that the  Company  obtains  the
approval  of its  stockholders  as  required  by the  Principal  Market  (or any
successor  rule or  regulation)  for issuances of Common Stock in excess of such
amount. Until such approval is obtained, the holder of this Warrant shall not be
issued,  upon exercise of this Warrant,  Warrant  Shares in an amount,  which if
added to the aggregate number of shares of common stock previously issued to the
holder of this  Warrant  (and all  predecessor  holders)  as of the date of such
exercise  would  exceed such  holder's  Cap  Allocation  Amount (as such term is
defined in the Convertible Debentures).  If at any time when the holder delivers
an Exercise  Notice pursuant to Section 2 hereof the Company shall be prohibited
pursuant to the  provisions of this Section 13 from issuing any Warrant  Shares,
then the Company shall pay in immediately  available funds to the holder of this
Warrant  within two (2) Business  Days of the date of delivery of such  Exercise
Notice,  an amount in cash  equal to the  product of (X) the number of shares of
Common Stock which could not be issued by virtue of the limitations contained in
this Section 13  multiplied  by (Y) the excess of (1) the average of the Closing
Sale Prices of the Common  Stock on each of the five (5) trading  days ending on
the third trading day  immediately  preceding the date such  prohibition  arises
over (2) the Warrant Exercise Price then in effect; provided,  however, that for
purposes of such  calculation  in no event shall such excess exceed 19.9% of the
Warrant  Exercise  Price then in  effect.  The  number of shares  issuable  upon
exercise of this  Warrant  shall be reduced for each share for which the Company
makes a cash payment pursuant to the preceding sentence.

Section 14. Judicial  Proceedings.  Any legal action, suit or proceeding brought
against the Company  with  respect to this Warrant may be brought in any federal
court of the  Southern  District of New York or any state  court  located in New
York County,  State of New York,  and by execution and delivery of this Warrant,
the Company hereby irrevocably and  unconditionally  waives any claim (by way of
motion,  as a defense or  otherwise) of improper  venue,  that it is not subject
personally  to  the  jurisdiction  of  such  court,  that  such  courts  are  an
inconvenient  forum  or that  this  Warrant  or the  subject  matter  may not be
enforced in or by such court. The Company hereby irrevocably and unconditionally
consents  to the service of process of any of the  aforementioned  courts in any
such action,  suit or proceeding by the mailing of copies  thereof by registered
or certified mail, postage prepaid,  at its address set forth or provided for in
Section 10, such service to become effective 10 days after such mailing. Nothing
herein  contained  shall be  deemed  to  affect  the right of any party to serve
process  in any  manner  permitted  by  law or  commence  legal  proceedings  or
otherwise  proceed against any other party in any other  jurisdiction to enforce
judgments  obtained in any action,  suit or proceeding  brought pursuant to this
Section.  The Company irrevocably  submits to the exclusive  jurisdiction of the
aforementioned courts in such action, suit or proceeding.

Section 15. DESCRIPTIVE HEADINGS; GOVERNING LAW. The descriptive headings of the
several  sections and  paragraphs  of this Warrant are inserted for  convenience
only and do not  constitute a part of this Warrant.  The  corporate  laws of the
State of New York shall govern all issues  concerning the relative rights of the
Company and its stockholders.  All other questions  concerning the construction,
validity,  enforcement and  interpretation  of this Warrant shall be governed by
the internal laws of the State of New York,  without giving effect to any choice
of law or conflict of law provision or rule (whether of the State of New York or
any other  jurisdiction)  that would  cause the  application  of the laws of any
jurisdiction other than the State of New York.






                  IN WITNESS WHEREOF,  the Company has caused this Warrant to be
signed by as of the 14th day of May, 2004.
