ITEM 5.           OTHER EVENTS AND REGULATION FD DISCLOSURE

         On June 12, 2003, the Company received  $1,550,000 from the two holders
("Debenture  Holders")  of the 6%  senior  secured  convertible  debentures  due
January  31,  2005  in  the  aggregate   principal  amount  of  $5,426,000  (the
"Debentures").  The  $1,550,000  represents  the balance of the proceeds due the
Company under the Debentures.  In connection  with the foregoing,  the Debenture
Holders  waived the  principal  conditions  under the  Debentures  required  for
release of such funds to the Company.

         On June 25, 2003, the Company issued to each of the Debenture Holders a
warrant to purchase up to 500,000  shares of the  Company's  Common  Stock for a
period  of five  years at an  initial  exercise  price of $2.40 per  share.  The
Company  has agreed to  register  the shares  issuable  upon  exercise  of these
warrants  in  accordance  with  terms  substantially  similar  to  those  in the
Company's  Registration  Rights  Agreement  dated March 12, 2003. For a complete
description  of the terms of these  warrants,  see the Form of Warrant  filed as
Exhibit 10.1 to this Report and incorporated herein by reference. For a complete
description  of the terms  pursuant  to which the Company has agreed to register
the shares issuable upon exercise of these warrants, see the Registration Rights
Agreement  filed as Exhibit  10.6 to the  Company's  Current  Report on Form 8-K
dated March 12, 2003 and filed with the  Securities  and Exchange  Commission on
March 13, 2003. Please note that the terms of the Registration  Rights Agreement
are modified as they relate to the shares issuable upon exercise of the Warrants
to the extent set forth in the Form of Warrant.

         On June 26, 2003,  the Debenture  Holders  exercised all 743,288 Common
Stock purchase  warrants issued to them on March 12, 2003. The Company  received
gross proceeds of $1,248,724 from this warrant exercise.

Warrant No. __    Number of Shares:  500,000
                  (subject to adjustment)

Date of Issuance:  June 25, 2003

     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  currently  held by the  holder  for cash and by the date
hereof, the receipt and sufficiency of which are hereby  acknowledged,________ ,
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 the date hereof, but
not after 11:59 P.M.,  New York City Time,  on the  Expiration  Date (as defined
herein)  500,000  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 March 12, 2003 (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  1,350,000  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.

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.

     Section 3. COVENANTS AS TO COMMON STOCK.  The Company hereby  covenants and
agrees 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.

b. All  Warrant  Shares  which may be issued  upon the  exercise  of the  rights
represented by this Warrant will, upon issuance and payment hereof in accordance
with the terms hereof, be validly issued,  fully paid and nonassessable and free
from all taxes, liens and charges created by or through the Company with respect
to the issue thereof.

c. During the period within which the rights  represented by this Warrant may be
exercised,  the Company will at all times have  authorized and reserved at least
135% of the number of shares of Common  Stock needed to provide for the exercise
of the rights then represented by this Warrant (without regard to any limitation
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.

     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.  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.

     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 (as defined below), 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 capital
reorganization of the Company,  any  reclassification or recapitalization of the
capital stock of the Company,  any consolidation or merger involving the Company
and any other Person,  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 transfer,  sale or other disposition of all or substantially all
the assets of the  Company to any other  Person  (each,  an  "Organic  Change"),
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

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
Executive Officer as provided for below. The addresses and facsimile numbers for

     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 June 25, 2003 (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.  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.
