Gentlemen:

Reference  is made to the  Warrant  (No.  ACA-2),  dated  December  6, 2002 (the
"Warrant"), of NCT Group, Inc., a Delaware corporation (the "Company"), pursuant
to which Alpha Capital  Aktiengesellschaft  (the "Holder") is granted the right,
subject to terms and  conditions  of the Warrant,  to purchase up to  15,000,000
shares (the  "Warrant  Shares") of common  stock,  par value $.01 per share (the
"Common  Stock"),  of the Company.  As of the date hereof,  the Warrant  remains
unvested and unexercised as to all 15,000,000 Warrant Shares.

Section 1.7 of the Warrant is hereby amended to read in its entirety as follows:

          1.7 Vesting.  This Warrant shall vest and become  exerciseable  in its
     entirety as of the date,  if any,  that the events in either  clause (a) or
     clause (b) below have occurred (the "Vesting Date"):

          (a) Both (i) the  Company  has  failed to pay,  on or prior to May 30,
     2003 (the  "Reference  Date"),  any amount  owed by the  Company  under the
     Promissory  Note,  dated as of the date hereof,  in the principal amount of
     $385,000.00,  made by the Company to the Holder  (the  "Note") and (ii) the
     Company has failed to pay, by the  Reference  Date,  any amount owed by the
     Company under any Registration  Penalty  Provision (as defined in Exhibit A
     hereto)  and such  payment  obligation  has not been  otherwise  discharged
     (provided,  that if the event  described in clause (i) above occurs but the
     event  described  in clause  (ii) above does not occur,  then this  Warrant
     shall vest and become  exerciseable under this clause (a) as to two million
     (2,000,000) shares of Warrant Stock only); or

          (b) The Holder and selling broker have provided  reasonably  requested
