                                FONAR CORPORATION

                              AMENDED AND RESTATED
                                PURCHASE WARRANT

                    WARRANT ("WARRANT") TO PURCHASE SHARES OF
                    COMMON STOCK, $0.0001 PAR VALUE PER SHARE

     This is to certify  that,  for VALUE  RECEIVED,  THE TAIL WIND  FUND,  LTD.
("Warrantholder"),  is entitled to purchase,  subject to the  provisions of this
Warrant,  from Fonar  Corporation,  a  corporation  organized  under the laws of
Delaware ("Company"),  at any time after the date of the issuance hereof but not
later  than 5:00  P.M.,  Eastern  time,  on May 24,  2009  ("Expiration  Date"),
1,000,000 shares ("Warrant Shares") of Common Stock,  $0.0001 par value ("Common
Stock"),  of the  Company,  at an  exercise  price per share equal to $0.79 (the
exercise  price in effect from time to time  hereafter  being herein  called the
"Warrant Price"). The number of Warrant Shares purchasable upon exercise of this
Warrant and the Warrant Price shall be subject to  adjustment  from time to time
as described herein.

     This  Warrant  has  been  issued  pursuant  to the  terms  of the  Purchase
Agreement  ("Purchase  Agreement") dated on or about the date hereof between the
Company  and the  Warrantholder.  Capitalized  terms used herein and not defined
shall have the meaning specified in the Purchase Agreement.

     Section 1. Registration.  The Company shall maintain books for the transfer
and registration of the Warrant.  Upon the initial issuance of the Warrant,  the
Company shall issue and register the Warrant in the name of the Warrantholder.

     Section 2. Transfers.  As provided herein,  this Warrant may be transferred
only pursuant to a  registration  statement  filed under the  Securities  Act of
1933,  as  amended   ("Securities   Act")  or  an  exemption  from  registration
thereunder.  Subject to such  restrictions,  the  Company  shall  transfer  this
Warrant from time to time,  upon the books to be  maintained  by the Company for
that  purpose,   upon  surrender  hereof  for  transfer   properly  endorsed  or
accompanied by appropriate instructions for transfer upon any such transfer, and
a new Warrant  shall be issued to the  transferee  and the  surrendered  Warrant
shall be canceled by the Company.

     Section 3.

     (a)  Exercise  of  Warrant.   Subject  to  the   provisions   hereof,   the
Warrantholder may exercise this Warrant in whole or in part at any time and from
time to time after the date of issuance  hereof upon  surrender  of the Warrant,
together  with  delivery of the duly  executed  Warrant  exercise  form attached
hereto (the "Exercise  Agreement")  (which may be by fax), to the Company during
normal business hours on any business day at the Company's  principal  executive
offices (or such other  office or agency of the Company as it may  designate  by
notice to the  holder  hereof),  and upon  payment to the  Company  in cash,  by
certified  or  official  bank check or by wire  transfer  for the account of the
Company of the Warrant  Price for the Warrant  Shares  specified in the Exercise
Agreement.  The Warrant Shares so purchased  shall be deemed to be issued to the
holder hereof or such holder's designee,  as the record owner of such shares, as
of the close of business on the date on which the completed  Exercise  Agreement
shall have been delivered to the Company (or such later date as may be specified
in the Exercise  Agreement).  Certificates  for the Warrant Shares so purchased,
representing the aggregate number of shares specified in the Exercise Agreement,
shall be delivered to the holder hereof within a reasonable  time, not exceeding
three (3) business  days,  after this Warrant shall have been so exercised.  The
certificates so delivered shall be in such  denominations as may be requested by
the holder  hereof and shall be  registered  in the name of such  holder or such
other name as shall be  designated  by such holder.  If this Warrant  shall have
been exercised only in part, then, unless this Warrant has expired,  the Company
shall (subject to Section 3(b) below),  at its expense,  at the time of delivery
of such  certificates,  deliver to the  holder a new  Warrant  representing  the
number of shares  with  respect to which this  Warrant  shall not then have been
exercised.

     (b) Book-Entry.  Notwithstanding anything to the contrary set forth herein,
upon  exercise  of any  portion  of this  Warrant in  accordance  with the terms
hereof,  the  Warrantholder  shall not be required to physically  surrender this
Warrant to the  Company  unless  such  holder is  purchasing  the full amount of
Warrant Shares  represented by this Warrant.  The  Warrantholder and the Company
shall  maintain  records  showing  the  number of  Warrant  Shares so  purchased
hereunder  and the  dates of such  purchases  or shall  use such  other  method,
reasonably  satisfactory  to the  Warrantholder  and the  Company,  so as not to
require  physical  surrender  of this  Warrant  upon  each  such  exercise.  The
Warrantholder and any assignee,  by acceptance of this Warrant or a new Warrant,
acknowledge  and agree  that,  by reason of the  provisions  of this  paragraph,
following exercise of any portion of this Warrant,  the number of Warrant Shares
which may be purchased upon exercise of this Warrant may be less than the number
of Warrant Shares set forth on the face hereof.

     Section 4. Compliance with the Securities Act of 1933. Neither this Warrant
nor the Common Stock issued upon exercise  hereof nor any other security  issued
or  issuable  upon  exercise  of this  Warrant  may be offered or sold except as
provided in this Warrant and in conformity  with the  Securities Act of 1933, as
amended,  and then only  against  receipt of an agreement of such person to whom
such offer of sale is made to comply with the  provisions of this Section 4 with
respect to any resale or other  disposition  of such  security.  The Company may
cause the legend set forth on the first page of this  Warrant to be set forth on
each Warrant or similar legend on any security  issued or issuable upon exercise
of this Warrant until the Warrant  Shares have been  registered for resale under
the Registration Rights Agreement or until Rule 144 is available, unless counsel
for the  Company is of the opinion as to any such  security  that such legend is
unnecessary.

     Section 5.  Payment of Taxes.  The Company will pay any  documentary  stamp
taxes  attributable to the initial  issuance of Warrant Shares issuable upon the
exercise  of the  Warrant;  provided,  however,  that the  Company  shall not be
required to pay any tax or taxes which may be payable in respect of any transfer
involved in the issuance or delivery of any certificates for Warrant Shares in a
name  other  than that of the  registered  holder of this  Warrant in respect of
which such shares are issued.  The holder shall be responsible  for income taxes
due under federal or state law, if any such tax is due.

     Section 6.  Mutilated or Missing  Warrants.  In case this Warrant  shall be
mutilated,  lost, stolen, or destroyed,  the Company shall issue in exchange and
substitution of and upon  cancellation of the mutilated  Warrant,  or in lieu of
and  substitution  for the Warrant lost,  stolen or destroyed,  a new Warrant of
like tenor and for the  purchase  of a like number of Warrant  Shares,  but only
upon receipt of evidence  reasonably  satisfactory  to the Company of such loss,
theft or  destruction  of the  Warrant,  and with  respect to a lost,  stolen or
destroyed  Warrant,  reasonable  indemnity  or bond  with  respect  thereto,  if
reasonably requested by the Company.

     Section 7. Reservation of Common Stock.  The Company hereby  represents and
warrants that there have been reserved,  and the Company shall at all applicable
times keep reserved,  out of the authorized and unissued  Common Stock, a number
of shares  sufficient  to provide  for the  exercise  of the rights of  purchase
represented  by the  Warrant  in full  (without  regard to any  restrictions  on
beneficial  ownership  contained herein),  and the transfer agent for the Common
Stock,  including every subsequent  transfer agent for the Common Stock or other
shares of the Company's  capital stock  issuable upon the exercise of any of the
right of purchase aforesaid ("Transfer Agent"),  shall be irrevocably authorized
and  directed at all times to reserve  such number of  authorized  and  unissued
shares of Common  Stock as shall be  requisite  for such  purpose.  The  Company
agrees that all Warrant Shares issued upon exercise of the Warrant in accordance
with its terms shall be, at the time of delivery  of the  certificates  for such
Warrant Shares, duly authorized,  validly issued,  fully paid and non-assessable
shares of Common Stock of the Company. The Company will keep a conformed copy of
this Warrant on file with its Transfer Agent.  The Company will supply from time
to time the Transfer  Agent with duly executed  stock  certificates  required to
honor the outstanding Warrant.

     Section 8. Warrant  Price.  The Warrant  Price,  subject to  adjustment  as
provided in Section 9, shall, if payment is made in cash or by certified  check,
be payable in lawful money of the United States of America.

     Section 9.  Adjustments.  Subject and  pursuant to the  provisions  of this
Section  9, the  Warrant  Price and  number of  Warrant  Shares  subject to this
Warrant  shall  be  subject  to  adjustment  from  time  to  time  as set  forth
hereinafter.

     (a) If the  Company  or any of its  subsidiaries  shall at any time or from
time  to time  while  the  Warrant  is  outstanding,  pay a  dividend  or make a
distribution  on its  capital  stock in shares of Common  Stock,  subdivide  its
outstanding  shares of Common  Stock into a greater  number of shares or combine
its   outstanding   shares  into  a  smaller   number  of  shares  or  issue  by
reclassification  of its  outstanding  shares of Common  Stock any shares of its
capital  stock  (including  any  such  reclassification  in  connection  with  a
consolidation  or merger in which the  Company is the  continuing  corporation),
then the number of Warrant Shares  purchasable  upon exercise of the Warrant and
the Warrant Price in effect immediately prior to the date upon which such change
shall  become  effective,   shall  be  adjusted  by  the  Company  so  that  the
Warrantholder thereafter exercising the Warrant shall be entitled to receive the
number of shares of Common Stock or other capital stock which the  Warrantholder
would have received if the Warrant had been exercised  immediately prior to such
event.  Such  adjustment  shall be made  successively  whenever any event listed
above shall occur.

     (b) If any capital reorganization, reclassification of the capital stock of
the Company, consolidation or merger of the Company with another corporation, or
sale, transfer or other disposition of all or substantially all of the Company's
assets to another  corporation  shall be effected,  then, as a condition of such
reorganization, reclassification, consolidation, merger, sale, transfer or other
disposition,   lawful  and  adequate   provision  shall  be  made  whereby  each
Warrantholder  shall  thereafter have the right to purchase and receive upon the
basis and upon the  terms and  conditions  herein  specified  and in lieu of the
Warrant Shares  immediately  theretofore  issuable upon exercise of the Warrant,
such  shares of stock,  securities  or assets  as would  have been  issuable  or
payable with  respect to or in exchange for a number of Warrant  Shares equal to
the number of Warrant Shares immediately  theretofore  issuable upon exercise of
the Warrant, had such reorganization,  reclassification,  consolidation, merger,
sale,  transfer  or other  disposition  not  taken  place,  and in any such case
appropriate  provision shall be made with respect to the rights and interests of
each  Warrantholder to the end that the provisions  hereof  (including,  without
limitations,  provision for adjustment of the Warrant Price) shall thereafter be
applicable, as nearly equivalent as may be practicable in relation to any shares
of stock,  securities or  properties  thereafter  deliverable  upon the exercise
hereof.  The  Company  shall not effect any such  consolidation,  merger,  sale,
transfer  or  other  disposition  unless  prior  to or  simultaneously  with the
consummation  thereof  the  successor  corporation  (if other than the  Company)
resulting from such  consolidation or merger,  or the corporation  purchasing or
otherwise acquiring such assets or other appropriate corporation or entity shall
assume,  by written  instrument  executed  and  delivered  to the  Company,  the
obligation  to  deliver  to the  holder  of the  Warrant  such  shares of stock,
securities  or assets as, in  accordance  with the  foregoing  provisions,  such
holder may be entitled to purchase and the other obligations under this Warrant.
The  provisions  of this  paragraph  (b)  shall  similarly  apply to  successive
reorganizations, reclassifications, consolidations, mergers, sales, transfers or
other dispositions.

     (c) In case the  Company  shall  fix a  record  date  for the  making  of a
distribution  to all holders of Common Stock  (including  any such  distribution
made in connection  with a  consolidation  or merger in which the Company is the
continuing  corporation)  of evidences of indebtedness or assets or subscription
rights or  warrants,  the Warrant  Price to be in effect  after such record date
shall be determined by multiplying the Warrant Price in effect immediately prior
to such  record date by a fraction,  the  numerator  of which shall be the total
number of shares of Common Stock outstanding multiplied by the Fair Market Value
per share of Common Stock (as defined  below),  less the fair market value (on a
per share  basis) (as  determined  by the  Company's  Board of Directors in good
faith) of said assets or evidences of indebtedness  so  distributed,  or of such
subscription rights or warrants, and the denominator of which shall be the total
number of shares of Common  Stock  outstanding  multiplied  by such current Fair
Market  Value  per  share  of  Common  Stock.  Such  adjustment  shall  be  made
successively  whenever  such a record date is fixed.  "Fair Market Value" of the
Common  Stock shall be the closing  price of the Common Stock as reported by the
Nasdaq  Stock  Market (or other  exchange or market on which the Common Stock is
principally  traded) on the trading day immediately  preceding the date on which
such value is being determined.

     (d) For the  duration  of the term of this  Warrant,  if the Company or any
subsidiary  shall at any  time or from  time to time  issue  or sell  securities
(other than issuances of Underlying  Shares  pursuant to Debentures and Warrants
under the Purchase  Agreement,  shares or options  issued or which may be issued
pursuant to the Company's  current  employee or director  option plans or shares
issued upon exercise of options,  warrants or rights  outstanding on the date of
the Agreement  and listed in the Company's SEC Filings and other than  issuances
described in and permitted  under  7.2(b)(iii) of the Purchase  Agreement) at an
effective a Per Share  Selling  Price (as defined  below) which is less than the
Warrant Price,  then in each such case, the Warrant Price in effect  immediately
prior  to  such  issue  or  sale  shall  be  automatically   reduced   effective
concurrently  with such issue or sale to an amount determined by multiplying the
Warrant Price then in effect by a fraction,  (x) the numerator of which shall be
the sum of (1) the  number of shares of  Common  Stock  outstanding  immediately
prior to such issue or sale, plus (2) the number of shares of Common Stock which
the aggregate  consideration  received by the Company for such additional shares
would purchase at the Warrant Price,  and (y) the  denominator of which shall be
the  number of shares of Common  Stock of the  Company  outstanding  immediately
after such issue or sale.

     The foregoing  provision of this subsection shall not apply to issuances or
sales  pursuant to the  Company's  duly adopted  employee or director  bona fide
options  plans  and/or  compensation  arrangements  or  to  issuances  of  up to
1,500,000  shares of the Company's  Common Stock to the stockholders of Advanced
Medical Diagnostic Corporation, a majority-owned subsidiary of Fonar ("AMD"), in
exchange for their shares of stock of AMD (which shall not be a capital  raising
transaction).

     For the purposes of the foregoing  adjustment,  in the case of the issuance
of any convertible  securities,  warrants,  options or other rights to subscribe
for or to  purchase  or  exchange  for,  shares  of Common  Stock  ("Convertible
Securities"),  the  maximum  number  of shares of  Common  Stock  issuable  upon
exercise,  exchange or conversion of such Convertible Securities shall be deemed
to be outstanding,  provided that no further  adjustment  shall be made upon the
actual  issuance of Common Stock upon  exercise,  exchange or conversion of such
Convertible Securities.

     For the  purposes of this Section  9(d),  "Per Share  Selling  Price" shall
include  the  amount  actually  paid by third  parties  for each share of Common
Stock.  In the  event a fee is paid  by the  Company  in  connection  with  such
transaction,  any such fee shall be deducted  from the selling price pro rata to
all shares sold in the  transaction  to arrive at the Per Share Selling Price. A
sale of shares of Common  Stock  shall  include  the sale or issuance of rights,
options,  warrants or convertible,  exchangeable or exercisable securities under
which the Company is or may become  obligated to issue  shares of Common  Stock,
and in such  circumstances  the Per  Share  Selling  Price of the  Common  Stock
covered  thereby shall also include the exercise,  exchange or conversion  price
thereof (in addition to the consideration received by the Company upon such sale
or issuance less the fee amount as provided above). In case of any such security
issued in a  Variable  Rate  Transaction  or an MFN  Transaction,  the Per Share
Selling Price shall be deemed to be the lowest  conversion or exercise  price at
which such securities are converted or exercised or might have been converted or
exercised in the case of a Variable Rate  Transaction,  or the lowest adjustment
price in the case of an MFN Transaction,  over the life of such  securities.  If
shares are issued for a  consideration  other than cash,  the Per Share  Selling
Price shall be the fair value of such  consideration as determined in good faith
by independent  certified public accountants  mutually acceptable to the Company
and the Purchaser.

     (e) An adjustment shall become effective  immediately after the record date
in the case of each dividend or distribution and immediately after the effective
date of each other event which requires an adjustment.

     (f) In the  event  that,  as a result of an  adjustment  made  pursuant  to
Section 9, the holder of this  Warrant  shall  become  entitled  to receive  any
shares of capital stock of the Company  other than shares of Common  Stock,  the
number of such other shares so receivable upon exercise of this Warrant shall be
subject  thereafter to adjustment  from time to time in a manner and on terms as
nearly  equivalent as practicable to the provisions  with respect to the Warrant
Shares contained in this Warrant.

     (g) In the event of any adjustment in the number of Warrant Shares issuable
hereunder  upon exercise,  the Warrant Price shall be inversely  proportionately
increased or  decreased,  as the case may be, such that the  aggregate  purchase
price for Warrant  Shares upon full  exercise of this  Warrant  shall remain the
same. Similarly, in the event of any adjustment in the Warrant Price, the number
of  Warrant  Shares   issuable   hereunder  upon  exercise  shall  be  inversely
proportionately  increased  or  decreased,  as the  case may be,  such  that the
aggregate  purchase  price for Warrant Shares upon full exercise of this Warrant
shall remain the same.

     Section 10. Fractional Interest. The Company shall not be required to issue
fractions of Warrant Shares upon the exercise of the Warrant. If any fraction of
a Warrant Share would,  except for the  provisions of this Section,  be issuable
upon the exercise of the Warrant (or specified  portions  thereof),  the Company
shall round such  calculation  to the nearest  whole  number and  disregard  the
fraction.

     Section 11.  Benefits.  Nothing in this Warrant  shall be construed to give
any person,  firm or corporation  (other than the Company and the Warrantholder)
any legal or equitable right, remedy or claim, it being agreed that this Warrant
shall  be  for  the  sole  and   exclusive   benefit  of  the  Company  and  the
Warrantholder.

     Section  12.  Notices to  Warrantholder.  Upon the  happening  of any event
requiring an adjustment of the Warrant Price,  the Company shall  forthwith give
written  notice  thereof to the  Warrantholder  at the address  appearing in the
records of the  Company,  stating the  adjusted  Warrant  Price and the adjusted
number of  Warrant  Shares  resulting  from  such  event  and  setting  forth in
reasonable  detail  the  method of  calculation  and the facts  upon  which such
calculation  is  based.  In the  event of a  dispute  with  respect  to any such
calculation,  the  certificate  of the Company's  independent  certified  public
accountants  shall be conclusive  evidence of the correctness of any computation
made, absent manifest error. Failure to give such notice to the Warrantholder or
any defect  therein  shall not affect the  legality  or  validity of the subject
adjustment.  At the  Warrantholder's  request,  the Company shall deliver to the
Warrantholder  as of a requested date a notice  specifying the Warrant Price and
the number of Warrant  Shares into which this Warrant is  exercisable as of such
date.

     Section 13. Identity of Transfer Agent.  The initial Transfer Agent for the
Common Stock is:

                  Computershare (f/k/a Securities Transfer Trust, Inc.)
                  350 Indiana Street, Suite 800
                  Golden, Colorado 80401

     Forthwith upon the  appointment  of any  subsequent  transfer agent for the
Common Stock or other shares of the Company's  capital  stock  issuable upon the
exercise of the rights of purchase  represented by the Warrant, the Company will
fax to the  Warrantholder a statement setting forth the name and address of such
transfer agent.

     Section 14. Notices.  Any notice pursuant hereto to be given or made by the
Warrantholder  to or on the  Company  shall  be  sufficiently  given  or made if
delivered personally or by facsimile or if sent by an internationally recognized
courier, addressed as follows:

                  Fonar Corporation
                  110 Marcus Drive

                  Fax:              (631) 249-3734

or such other  address as the  Company  may  specify in writing by notice to the
Warrantholder complying as to delivery with the terms of this Section 14.

     Any notice  pursuant hereto to be given or made by the Company to or on the
Warrantholder shall be sufficiently given or made if personally  delivered or if
sent by an  internationally  recognized  courier service by overnight or two-day
service,  to the address set forth on the books of the Company or, as to each of
the Company and the Warrantholder,  at such other address as shall be designated
by such party by written notice to the other party complying as to delivery with
the terms of this Section 14.

     All such notices,  requests,  demands,  directions and other communications
shall,  when sent by courier,  be effective two (2) days after  delivery to such
courier as provided  and  addressed as  aforesaid.  All faxes shall be effective
upon receipt.

     Section 15.  Registration  Rights.  The initial  holder of this  Warrant is
entitled to the benefit of certain registration rights in respect of the Warrant
Shares as provided in the Registration Rights Agreement.

     Section 16.  Successors.  All the covenants and provisions hereof by or for
the  benefit of the  Warrantholder  shall  bind and inure to the  benefit of its
respective successors and assigns hereunder.

     Section 17.  Governing  Law.  This Warrant shall be deemed to be a contract
made  under  the laws of the  State of New York,  without  giving  effect to its
conflict  of law  principles,  and  for  all  purposes  shall  be  construed  in
accordance with the laws of said State.


     Section 18. 4.9% and 19.9% Limitations.

          (a)  Notwithstanding  anything to the contrary  contained herein,  the
     number of shares of Common  Stock that may be  acquired  by the holder upon
     exercise  pursuant to the terms hereof shall not exceed a number that, when
     added to the total  number of shares of Common  Stock  deemed  beneficially
     owned by such holder at such time (other than by virtue of the ownership of
     securities or rights to acquire  securities  (including the Warrant Shares)
     that  have  limitations  on the  holder's  right to  convert,  exercise  or
     purchase  similar to the limitation  set forth  herein),  together with all
     shares of Common Stock deemed  beneficially  owned (other than by virtue of
     the  ownership  of  securities  or rights to acquire  securities  that have
     limitations  on the right to convert,  exercise or purchase  similar to the
     limitation set forth herein) by the  Warrantholder's  "affiliates"  at such
     time (as defined in Rule 144 of the Act) ("Aggregation Parties") that would
     be  aggregated  for purposes of  determining  whether a group under Section
     13(d) of the  Securities  Exchange Act of 1934, as amended,  exists,  would
     exceed 4.9% of the total issued and outstanding  shares of the Common Stock
     (the "Restricted Ownership  Percentage").  Each holder shall have the right
     (x) at any time and from time to time to reduce  its  Restricted  Ownership
     Percentage  immediately  upon  notice to the  Company  and (y)  (subject to
     waiver)  at any time and from  time to time,  to  increase  its  Restricted
     Ownership  Percentage  immediately  in the  event  of the  announcement  as
     pending or planned, of a change of control  transaction  (including without
     limitation a  transaction  that would result in a transfer of more than 50%
     of the Company's voting power or equity,  or a sale of all or substantially
     all of the Company's assets, or a transaction that would result in a person
     or  "group"  being  deemed  the  beneficial  owner  of 50% or  more  of the
     Company's voting power or equity).

          (b) The Company's  obligation to issue Common Stock which would exceed
     such limits referred to in this Section 18 shall be suspended to the extent
     necessary  until such time, if any, as shares of Common Stock may be issued
     in compliance with such restrictions.

          (c)  Notwithstanding  anything contained herein, in the event that the
     Warrantholder  has timely exercised this Warrant and the issuance of all or
     a portion of the  Warrant  Shares to be issued  pursuant  to such  exercise
     would constitute a breach of the Company's  obligations  under the rules or
     regulations of the Nasdaq Stock Market as they apply to the Company, or any
     other principal  securities  exchange or market  ("Principal  Market") upon
     which the Common Stock is or becomes traded (the "Cap  Regulations"),  then
     the Company shall not be obligated to issue any such Warrant  Shares to the
     extent such shares are in excess of the maximum  permissible  amount  under
     such Cap Regulations ("Excess Shares").  Within five (5) days following any
     occurrence  of  Excess  Shares,  the  Company  shall  promptly  pay  to the
     Purchaser,  in lieu of the Purchaser's right to receive such Excess Shares,
     an amount equal to 120% of the difference  between (a) the number of Excess
     Shares  multiplied  by the closing  sale price per share of Common Stock on
     the Principal  Market on the trading day immediately  preceding the date of
     the exercise of this Warrant, and (b) the aggregate exercise price for such
     Excess  Shares.  Only  shares  of Common  Stock  acquired  pursuant  to the
     Purchase Agreement (including Underlying Shares and Warrant Shares) will be
     included in determining  whether the limitation  contained  herein would be
     exceeded for purposes of this Section 18(c).

     Section 19. Replacement  Warrants.  The Company agrees that within ten (10)
business days after any request from time to time of the Warrantholder, it shall
deliver to such holder a new Warrant in  substitution  of this Warrant  which is
identical  in  all  respects  except  that  the  then  Warrant  Price  shall  be
appropriately  specified in the Warrant, and the Warrant shall specify the fixed
number of  Warrant  Shares  into which this  Warrant is then  exercisable.  Such
changes are intended not as amendments to the Warrant but only as  clarification
of the foregoing  numbers for convenience  purposes,  and such changes shall not
affect any provisions  concerning  adjustments to the Warrant Price or number of
Warrant Shares contained herein.

     Section 20.  Absolute  Obligation  to Issue Warrant  Shares.  The Company's
obligations  to issue and deliver  Warrant  Shares in accordance  with the terms
hereof are absolute and unconditional, irrespective of any action or inaction by
the holder hereof to enforce the same, any waiver or consent with respect to any
provision hereof,  the recovery of any judgment against any Person or any action
to enforce the same,  or any setoff,  counterclaim,  recoupment,  limitation  or
termination,  or any breach or alleged  breach by the holder hereof or any other
Person of any obligation to the Company or any violation or alleged violation of
law  by  the  holder  or  any  other  Person,  and  irrespective  of  any  other
circumstance  which might  otherwise limit such obligation of the Company to the
holder hereof in  connection  with the issuance of Warrant  Shares.  The Company
will at no time close its  shareholder  books or  records  in any  manner  which
interferes with the timely exercise of this Warrant.

     Section 21. Assignment,  Etc. The Warrantholder may assign or transfer this
Warrant to any  transferee  only with the prior written  consent of the Company,
which  may not be  unreasonably  withheld  or  delayed,  provided  that  (i) the
Warrantholder may assign or transfer this Warrant to any of such Warrantholder's
affiliates without the consent of the Company and (ii) upon any Event of Default
(as defined in the Debentures),  the  Warrantholder  may assign or transfer this
Warrant without the consent of the Company.  The Warrantholder  shall notify the
Company of any such  assignment  or transfer  promptly.  This  Warrant  shall be
binding  upon the Company and its  successors  and shall inure to the benefit of
the Warrantholder and its successors and permitted assigns.
