                             STOCK OPTION AGREEMENT

     STOCK OPTION AGREEMENT,  dated as of May 22, 2003, between NCT Group, Inc.,
a Delaware corporation (the "Company"),  and Turbo Networks,  Inc., a New Jersey
corporation ("Optionee").

     The Company  hereby grants to Optionee  options to acquire  Common Stock of
the Company upon the following terms and conditions:

     1. Grant of Options. The Company grants to Optionee options (the "Options")
to purchase up to Eighteen  Million Five  Hundred  Fifty  Thousand  (18,550,000)
fully  paid and  nonassessable  shares of the Common  Stock,  par value $.01 per
share,  of the Company  (the  "Shares"),  to be issued upon the  exercise of the
Options,  as set forth below.  Such Options are granted  pursuant to the May 22,
2003 First  Amendment  of the April 17, 2003  Consulting  Agreement  between the
Company and Optionee (the "Agreement").

     2.  Exercise  Price.  The exercise  price of the Options shall be $.042 per
Share.  The  Company  shall  pay all  original  issue or  transfer  taxes on the
exercise of the Options.

     3. Vesting of Options. The Options shall vest as of the date hereof.

     4.  Expiration of Options.  The Options shall expire and not be exercisable
after May 22, 2008.

     5. Non-Assignability of Options.  Except as set forth in Section 12 hereof,
the Options shall not be given, granted, sold, exchanged,  transferred, pledged,
assigned  or  otherwise  encumbered  or  disposed  of by  Optionee  and shall be
exercisable only by Optionee or its agent or attorney-in-fact.




     6.  Method of Exercise of  Options.  Optionee  shall  notify the Company by
written notice sent by certified mail,  return receipt  requested,  addressed to
the Company's  principal  office,  or by hand delivery to such office, as to the
number of Shares which  Optionee  desires to purchase  under the options,  which
written notice shall be accompanied by Optionee's  check payable to the order of
the Company for the full option  price of such  Shares.  As soon as  practicable
after the receipt of such written  notice,  the Company shall,  at its principal
office,  tender to Optionee a certificate or  certificates  issued in Optionee's
name evidencing the Shares purchased by Optionee hereunder.

     7. Shares of Common Stock as Investment. By accepting the Options, Optionee
agrees that any and all Shares  purchased  upon the  exercise  thereof  shall be
acquired for investment and not for  distribution,  and upon the issuance of any
or all of the  Shares  subject to the  Options,  Optionee  shall  deliver to the
Company a representation  in writing that such Shares are being acquired in good
faith for  investment  and not with a view toward  resale or  distribution.  The
Company  may  place an  appropriate  restrictive  legend on the  certificate  or
certificates evidencing such Shares.

     8. Adjustments upon Changes in  Capitalization.  In the event of changes in
the outstanding Common Stock of the Company by reason of stock dividends,  stock
splits, recapitalizations,  mergers, consolidations,  combinations, exchanges of
shares,  separations,  reorganization  or  liquidations,  the  number  of Shares
issuable  upon the exercise of the Options,  the exercise  price thereof and any
limitation  on exercise set forth in Section 3 hereof  shall be  correspondingly
adjusted by the Company. Any such adjustment in the number of Shares shall apply
proportionately  to  only  the  then  unexercised  portion  of the  Options.  If
fractional shares

                                       2



would result from any such  adjustment,  the adjustment  shall be revised to the
next lower whole number of shares.

     9.  No  Rights  as  Stockholders.  Optionee  shall  have  no  rights  as  a
stockholder in respect to the shares as to which the Options shall not have been
exercised and payment made as herein provided.

     10. Board  Approval.  The Option grants  described in Section 1 hereof have
been approved by the Board of Directors of the Company.

     11. Notices.  Notices,  demands and other  communications  given under this
Stock  Option  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
timely  notice as set forth in the "with a copy to"  provisions  below shall not
invalidate a notice  properly and timely given to the associated  party.  Unless
another  address or  facsimile  number is  specified  by notice  hereunder,  all
notices shall be sent as follows:
