                                     WARRANT

              for the Purchase of 6,750,000 Shares of Common Stock

     FOR  VALUE  RECEIVED,   NCT  GROUP,   INC.  (the  "Company"),   a  Delaware
corporation,  on this day of May 21, 2004 (the "Grant  Date") hereby issues this
warrant (the  "Warrant")  and certifies  that Carole  Salkind (the  "Holder") is
granted the right,  subject to the  provisions of the Warrant,  to purchase from
the Company,  at any time, or from time to time during the period  commencing at
9:00 a.m. New York City local time on May 21, 2004, and expiring, unless earlier
terminated as hereinafter provided, at 5:00 p.m. New York City local time on May
21, 2009 up to Six Million Seven Hundred Fifty Thousand  (6,750,000)  fully paid
and  nonassessable  shares of Common Stock,  $.01 par value, of the Company at a
price per share (the  "Exercise  Price")  equal to the closing sale price of the
Common  Stock  (as  defined  below)  on  the  Trading  Day  (as  defined  below)
immediately preceding the date of this Warrant;  provided,  however, that if, on
the date of this Warrant and the three Trading Days  thereafter  (the "Window"),
neither the Holder nor any Related Party (as defined below) sells or, whether in
writing or  otherwise,  agrees to sell any shares of Common Stock or any option,
warrant,  instrument  or right to convert into,  exchange for or acquire  Common
Stock,  then the Exercise  Price shall be reduced to a price equal to the lowest
closing sale price, if lower than the price specified above in this sentence, of
the Common  Stock  during the Window on the  principal  securities  exchange  or
market  on which  the  Common  Stock is then  traded as  reported  on  Bloomberg
Financial  Markets.  If any closing  sale price of the Common  Stock  during the
Window is lower than the price specified in the immediately  preceding sentence,
the  Holder  shall give the  Borrower  prompt  written  notice of any sale of or
agreement to sell any Common Stock or option,  warrant,  instrument  or right to
convert  into,  exchange  for or  acquire  Common  Stock made by the Holder or a
Related  Party during the Window.  "Trading Day" shall mean any day on which the
applicable  common stock is traded for any period on the NASDAQ National Market,
or on the principal  securities exchange or other securities market on which the
applicable  common  stock is then being  traded.  "Related  Party"  shall mean a
member of the Holder's immediate family,  including spouse (even if separated or
not residing with the Holder) and adult  children (even if not residing with the
Holder),  or an entity  (other than the Company) of which the Holder or any such
immediate  family  member is an  officer,  director  or  beneficial  shareholder
(determined  under Rule 13d-3  under the  Securities  Exchange  Act of 1934,  as
amended).

     The term "Common  Stock" means the shares of Common Stock,  $.01 par value,
of the Company constituted on the Grant Date of this Warrant,  together with any
other equity securities that may be issued by the Company in addition thereto or
in  substitution  therefor.  The number of shares of Common Stock to be received
upon  the  exercise  of  this  Warrant  may be  adjusted  from  time  to time as
hereinafter  set  forth.  The  shares  of  Common  Stock  deliverable  upon such
exercise,  and as adjusted from time to time, are hereinafter sometimes referred
to as "Warrant Stock".

     Upon receipt by the Company of evidence  reasonably  satisfactory  to it of
the loss, theft,  destruction or mutilation of this Warrant, and (in the case of
loss, theft or destruction) of reasonably satisfactory indemnification, and upon
surrender  and  cancellation  of this Warrant,  if mutilated,  the Company shall
execute and  deliver a new Warrant of like tenor and date.  Any such new Warrant
executed and delivered shall constitute an additional  contractual obligation on
the part of the Company,  whether or not this Warrant so lost, stolen, destroyed
or mutilated shall be at any time enforceable by anyone.

     The Holder agrees with the Company that this Warrant is issued, and all the
rights  hereunder shall be held,  subject to all of the conditions,  limitations
and provisions set forth herein.

     1.  Exercise of Warrant.  This Warrant may be exercised in whole or in part
at any time,  or from time to time,  during the period  commencing at 9:00 a.m.,
New York City local time, on May 21, 2004,  and expiring at 5:00 p.m.,  New York
City local  time,  on May 21,  2009,  or, if such day is a day on which  banking
institutions in the City of New York are authorized by law to close, then on the
next succeeding day that shall not be such a day.

     Subject to the restrictions  and limitations set forth above,  this Warrant
may be  exercised by  presentation  and  surrender  hereof to the Company at its
principal  office with the Warrant  Exercise Form attached  hereto duly executed
and  accompanied  by payment  (either in cash or by certified  or official  bank
check, payable to the order of the Company) of the Exercise Price for the number
of shares  specified in such Form and  instruments of transfer,  if appropriate,
duly executed by the Holder.  If this Warrant  should be exercised in part only,
the Company shall, upon surrender of this Warrant for cancellation,  execute and
deliver a new Warrant  evidencing  the rights of the Holder  thereof to purchase
the balance of the shares purchasable hereunder.  Upon receipt by the Company of
this Warrant, together with the Warrant Exercise Form and the Exercise Price, at
its office,  in proper form for  exercise,  the Holder shall be deemed to be the
holder of record of the  shares of Common  Stock  issuable  upon such  exercise,
notwithstanding  that the stock  transfer  books of the  Company  shall  then be
closed or that  certificates  representing such shares of Common Stock shall not
then be  actually  delivered  to the Holder.  The Company  shall pay any and all
documentary  stamp or similar issue or transfer  taxes payable in respect of the
issue or delivery of shares of Common Stock on exercise of this Warrant.

     2.  Reservation  of  Shares.  The  Company  will at all times  reserve  for
issuance and delivery  upon  exercise of this Warrant all shares of Common Stock
of the Company from time to

                                       2
<PAGE>


time  receivable  upon exercise of this  Warrant.  All such shares shall be duly
authorized and, when issued upon such exercise,  shall be validly issued,  fully
paid and nonassessable and free of all preemptive rights.

     3. Warrant Stock  Transfer to Comply with the  Securities  Act of 1933. The
Warrant  Stock  may not be sold  or  otherwise  disposed  of  unless  registered
pursuant to the  provisions of the Securities Act of 1933, as amended (the "1933
Act"), or an opinion of counsel in form and content  satisfactory to the Company
is obtained  stating that such sale or other  disposition  is made in compliance
with  an  available  exemption  from  such  registration.   Any  sale  or  other
disposition  of the Warrant  Stock must also comply  with all  applicable  state
securities laws and regulations.

     4. Fractional Shares. No fractional shares or scrip representing fractional
shares shall be issued upon the exercise of this Warrant,  but the Company shall
issue one  additional  share of its Common  Stock in lieu of each  fraction of a
share otherwise called for upon any exercise of this Warrant.

     5. Exchange,  Transfer,  Assignment of Loss of Warrant. This Warrant is not
registered  under the 1933 Act nor under any applicable  state securities law or
regulation.  This Warrant cannot be sold,  exchanged,  transferred,  assigned or
otherwise  disposed of unless registered  pursuant to the provisions of the 1933
Act or an opinion of counsel in form and content  satisfactory to the Company is
obtained  stating  that such  disposition  is in  compliance  with an  available
exemption  from  registration.  Any  such  disposition  must  also  comply  with
applicable state securities laws and regulations.

     6.  Rights of the  Holder.  The Holder  shall  not,  by virtue  hereof,  be
entitled  to any rights of a  stockholder  of the  Company,  either at law or in
equity,  and the  rights of the Holder are  limited to those  expressed  in this
Warrant.

     7. Redemption. This Warrant is not redeemable by the Company.

     8. Anti-Dilution Provisions.

         8.1  Adjustment  for Dividends  in Other  Securities,  Property,  Etc.:
     Reclassification,  Etc.  In case at any time or from time to time after the
     Grant Date the holders of Common Stock (or any other securities at the time
     receivable upon the exercise of this Warrant) shall have received, or on or
     after the record date fixed for the determination of eligible stockholders,
     shall have become entitled to receive without payment  therefor:  (a) other
     or additional  securities or property (other than cash) by way of dividend,
     (b) any cash paid or payable except out of earned surplus of the Company at
     the Grant Date as increased  (decreased)  by subsequent  credits  (charges)
     thereto (other than credits in respect of any capital or paid-in surplus or
     surplus  created as a result of a revaluation  of property) or (c) other or
     additional  (or less)  securities  or property  (including  cash) by way of
     stock-split, spin-off, split-up, reclassification, combination of shares or
     similar corporate rearrangement, then, and in each such case, the Holder of
     this Warrant,  upon the exercise thereof as provided in Section 1, shall be

                                       3
<PAGE>


     entitled to receive,  subject to the limitations and restrictions set forth
     above,  the amount of securities and property  (including cash in the cases
     referred to in clauses (b) and (c) above)  which such Holder  would hold on
     the date of such  exercise  if on the Grant  Date it had been the holder of
     record of the number of shares of Common Stock (as constituted on the Grant
     Date)  subscribed  for upon such  exercise as provided in Section 1 and had
     thereafter, during the period from the Grant Date to and including the date
     of such  exercise,  retained  such shares and/or all other  additional  (or
     less)  securities and property  (including cash in the cases referred to in
     clauses  (b) and (c)  above)  receivable  by it as  aforesaid  during  such
     period,  giving effect to all adjustments  called for during such period by
     Section 8.2.

         8.2  Adjustment for Reorganization, Consolidation, Merger, Etc. In case
     of any  reorganization  of the  Company  (or  any  other  corporation,  the
     securities  of which are at the time  receivable  on the  exercise  of this
     Warrant)  after the Grant Date or in case after such date the  Company  (or
     any such other  corporation)  shall  consolidate with or merge into another
     corporation  or convey  all or  substantially  all of its assets to another
     corporation,  then,  and in each such case, the Holder of this Warrant upon
     the  exercise  thereof  as  provided  in  Section  1 at any time  after the
     consummation of such reorganization,  consolidation,  merger or conveyance,
     shall be  entitled  to  receive,  in lieu of the  securities  and  property
     receivable  upon the exercise of this Warrant  prior to such  consummation,
     the  securities  or property to which such Holder would have been  entitled
     upon  such   consummation   if  such  Holder  had  exercised  this  Warrant
     immediately prior thereto, all subject to further adjustment as provided in
     Section  8.1;  in each  such  case,  the  terms  of this  Warrant  shall be
     applicable to the  securities or property  receivable  upon the exercise of
     this Warrant after such consummation.

         8.3  Certificate as to  Adjustments.  In each case of an  adjustment in
     the  number of shares of Common  Stock (or other  securities  or  property)
     receivable on the exercise of the Warrant,  the Company at its expense will
     promptly  compute  such  adjustment  in  accordance  with the  terms of the
     Warrant and prepare a certificate setting forth such adjustment and showing
     in detail  the facts  upon  which such  adjustment  is based,  including  a
     statement  of (a)  the  consideration  received  or to be  received  by the
     Company for any additional  shares of Common Stock issued or sold or deemed
     to have been  issued  or sold,  (b) the  number  of shares of Common  Stock
     outstanding  or deemed to be  outstanding,  and (c) the pro forma  adjusted
     Exercise.  The Company will forthwith mail a copy of each such  certificate
     to the holder of this Warrant.

         8.4  Notices of Record Date, Etc.

              In case:

          (a) the Company shall take a record of the holders of its Common Stock
     (or  other  securities  at the time  receivable  upon the  exercise  of the
     Warrant) for the purpose of entitling  them to receive any dividend  (other
     than a cash dividend) or other distribution, or any right to subscribe for,
     purchase or otherwise acquire any shares of stock of any class or any other
     securities, or to receive any other right; or

                                       4
<PAGE>


          (b) of any capital  reorganization  of the Company (other than a stock
     split or reverse stock split), any reclassification of the capital stock of
     the  Company,  any  consolidation  or  merger of the  Company  with or into
     another  corporation  (other  than a  merger  for  purposes  of  change  of
     domicile) or any  conveyance of all or  substantially  all of the assets of
     the Company to another corporation; or

          (c)  of any  voluntary  or  involuntary  dissolution,  liquidation  or
     winding-up of the Company,  then,  and in each such case, the Company shall
     mail or  cause to be  mailed  to each  holder  of the  Warrant  at the time
     outstanding a notice specifying,  as the case may be, (i) the date on which
     a record is to be taken for the purpose of such dividend,  distribution  or
     right, and stating the amount and character of such dividend,  distribution
     or right, or (ii) the date on which such reorganization,  reclassification,
     consolidation,  merger, conveyance, dissolution,  liquidation or winding-up
     is to take place,  and the time,  if any,  is to be fixed,  as to which the
     holders  of record of Common  Stock (or such other  securities  at the time
     receivable  upon the exercise of the Warrant) shall be entitled to exchange
     their shares of Common Stock (or such other  securities)  for securities or
     other  property  deliverable  upon such  reorganization,  reclassification,
     consolidation,  merger, conveyance, dissolution, liquidation or winding-up.
     Such  notice  shall be mailed at least  twenty  (20) days prior to the date
     therein  specified  and the  Warrant  may be  exercised  prior to said date
     during  the term of the  Warrant  no later than five (5) days prior to said
     date.

     9. Legend. In the event of the exercise of this Warrant and the issuance of
any of the Warrant Stock hereunder, all certificates  representing Warrant Stock
shall bear on the face thereof  substantially the following legends,  insofar as
is consistent with Delaware law:

        "The shares of common stock  represented by this certificate have
        not been registered under the Securities Act of 1933, as amended,
        or the Securities  laws of any state or other  jurisdiction,  and
        may not be sold,  offered  for  sale,  assigned,  transferred  or
        otherwise   disposed  of,  unless  registered   pursuant  to  the
        provisions of that Act and of such  Securities laws or an opinion
        of counsel acceptable to the Corporation is obtained stating that
        such  disposition  is in compliance  with an available  exemption
        from such registration."

     10. Governing Law and  Jurisdiction.  This Warrant shall be governed by the
internal  laws of the State of  Delaware,  without  regard to  conflicts of laws
principles.  The parties hereto hereby submit to the exclusive  jurisdiction  of
the United States Federal Courts located in the state of New Jersey with respect
to any dispute arising under this Warrant.

     11. Notices.  Notices,  demands and other  communications  given under this
Agreement  shall be in  writing  and shall be deemed  to have  been  given  when
delivered  (if  personally  delivered),  on the  scheduled  date of delivery (if
delivered  via  commercial  courier),  three  days  after  mailed  (if mailed by
certified  or  registered  mail,  return  receipt  requested)  or  when  sent by
facsimile  (if  sent by  facsimile  with  evidence  of  successful  transmission
retained by the  sender);  provided,  however,  that  failure to give proper and
