                                                                    $


FOR VALUE RECEIVED, NCT GROUP, INC., a Delaware corporation  (hereinafter called
the  "Borrower")  hereby  promises  to pay to the  order of  Carole  Salkind  or
registered       assigns       (the       "Holder")       the       sum       of
______________________________________________________________    (______)    on
__________,  and to pay interest on the unpaid principal balance hereof at eight
percent (8%) per annum (the "Ordinary  Interest Rate") from the date hereof (the
"Issue  Date") until the same  becomes due and  payable,  whether at maturity or
upon  acceleration or otherwise.  Any amount of principal of or interest on this
Note which is not paid when due shall bear  interest at the rate of five percent
(5%) above the Ordinary Interest Rate (the "Default Interest Rate") from the due
date thereof until the same is paid.  Interest  shall  commence  accruing on the
Issue Date and, to the extent not converted in accordance with the provisions of
Article II below,  shall be payable in arrears on the date the principal  amount
in  respect  of which  it has  accrued  is paid,  whether  at  maturity  or upon
acceleration  or by  prepayment  or  otherwise.  All payments of  principal  and
interest (to the extent not converted in accordance with the terms hereof) shall
be made in lawful money of the United States of America.  All payments  shall be
made at such  address as the Holder  shall  hereafter  give to the  Borrower  by
written notice made in accordance with the provisions of this Note.

The following terms shall apply to this Note:

                                    ARTICLE I

                                  NO PREPAYMENT

     1.1  PREPAYMENT.  This  Note is not  subject  to  prepayment.  This Note is
subject to optional conversion in accordance with Section 2.7 below.

                                   ARTICLE II

            CONVERSION AND PURCHASE RIGHTS; PAYMENT OF EXERCISE PRICE

     2.1  CONVERSION  RIGHT.  The Holder  shall have the right (the  "Conversion
Right") at any time on or prior to the day this Note is paid in full, to convert
at any time all or from  time to time any  part of the  outstanding  and  unpaid
principal  amount of this Note of at least  $50,000,  or such  lesser  amount as
shall remain unpaid at the time of the conversion,  into, at Holder's  election,
(i) fully paid and  non-assessable  shares of common  stock,  par value $.01 per
share, of the Borrower ("Common  Stock"),  at the conversion price determined by
Section  2.2(a)  hereof;  (ii) if Artera  (UK)  Limited  ("Artera")  has made an

<PAGE>


initial public  offering of its common stock,  par value  (pound)1.00 per share,
fully paid and non-assessable  shares of such stock owned by the Borrower,  at a
conversion price equal to the initial public offering price of such stock; (iii)
if  Distributed  Media  Corporation  International  Limited  ("DMCI") has made a
public offering of its common stock, par value (pound)1.00 per share, fully paid
and non-assessable  shares of such stock owned by the Borrower,  at a conversion
price equal to the initial public offering price of such stock;  and (iv) if any
other subsidiary of the Borrower (other than Pro Tech Communications,  Inc.) has
made a public offering of its common stock, fully paid and non-assessable shares
of such stock owned by the Borrower,  at a conversion price equal to the initial
public  offering  price  of  such  stock.  Upon  the  surrender  of  this  Note,
accompanied  by a Notice of Conversion of Secured  Convertible  Note in the form
attached hereto as Exhibit 1, properly completed and duly executed by the Holder
(a "Conversion Notice"),  the Borrower shall issue and, within five (5) business
days after such surrender of this Note with the Conversion Notice, deliver to or
upon the order of the Holder (x) that  number of shares of common  stock for the
portion of the Note converted as shall be determined in accordance  herewith and
(y) a new  Note in the form  hereof  for the  balance  of the  principal  amount
hereof, if any.

     The number of shares of common stock to be issued upon each  conversion  of
this Note shall be determined by dividing (i) the sum of (A) that portion of the
principal  amount  of the Note to be  converted  plus (B) the  "Conversion  Date
Interest" (as defined below), by (ii) the Conversion Price (as defined below) in
effect on the date the  Conversion  Notice is  delivered  to the Borrower by the
Holder.  Conversion Date Interest means the product of (i) the principal  amount
of the Note to be converted,  multiplied by (ii) a fraction (A) the numerator of
which is the number of days elapsed  since the date of issuance of this Note and
(B) the  denominator of which is 365,  multiplied by the Ordinary  Interest Rate
(iii) or, a  fraction  (A) the  numerator  of which is the number of days in the
period  of  time  after  the  occurrence  of an  Event  of  Default  and (B) the
denominator of which is 365, multiplied by the Default Interest Rate.

     2.2 CONVERSION PRICE.

     (a) The per share  "Conversion  Price" for conversion of this Note into the
Borrower's  Common  Stock  shall be  $________.  The  Conversion  Price shall be
subject  to  equitable   adjustments   for  stock   splits,   stock   dividends,
combinations, recapitalization, reclassifications and similar events. The Artera
and DMCI "Conversion  Price" shall be equal to the initial public offering price
of such stock and also be subject to  equitable  adjustments  for stock  splits,
stock dividends, combinations, reclassifications and similar events.

     (b) Borrower shall promptly notify each Holder of any adjustment (and event
that requires  adjustment) to the Conversion Price of Borrower,  Artera and DMCI
pursuant to this Section 2.2.

     2.3 AUTHORIZED  SHARES.  The Borrower  covenants that during the period the
Conversion Right exists,  the Borrower will use its best efforts to reserve from
its  authorized  and  unissued  Common  Stock a  sufficient  number of shares to
provide for the issuance of Common Stock upon the full  conversion of this Note.
The Borrower represents that upon issuance, such shares will be duly and validly
issued,  fully paid and  non-assessable.  The Borrower (i) acknowledges  that it
will  irrevocably  instruct its transfer  agent as soon as  practicable to issue
certificates for the Common Stock issuable upon conversion of this Note and (ii)
agrees that its  issuance of this Note shall  constitute  full  authority to its
officers  and  agents,  who  are  charged  with  the  duty  of  executing  stock
certificates,  to execute  and issue the  necessary  certificates  for shares of
Common Stock upon the  conversion  of this Note.  In the event that a sufficient
number of shares cannot be reserved,  Borrower agrees to use its best efforts to
call an annual meeting of the Borrower's  shareholders  and seek approval for an
increase in the authorized  shares of the Borrower's Common Stock to a number of
shares sufficient to provide for the full conversion of this Note.

     2.4 METHOD OF  CONVERSION.  Except as  otherwise  provided  in this Note or
agreed to by the Holder,  this Note may be  converted  by the Holder in whole at
any time or in part (provided such partial  conversion is at least $50,000) from
time to time by (i) submitting to the Borrower a Conversion Notice (by facsimile
dispatched on the  Conversion  Date and confirmed by U.S. mail or overnight mail
service sent within two business days  thereafter)  and (ii)  surrendering  this
Note with the mailed  confirmation  of the  Conversion  Notice at the  principal
office of the Borrower.  Upon partial exercise of the conversion rights provided
hereby, a new Note containing the same date and provisions as this Note shall be
issued by the  Borrower  to the  Holder for the  principal  balance of this Note
which shall not have been  converted.  This Note has been issued by the Borrower
pursuant to the exemption from  registration  provided  either by Section 4.2 or
Regulation D under the Securities Act of 1933, as amended (the "Act").

     2.5  RESTRICTIONS  ON SHARES.  The  shares of common  stock  issuable  upon
conversion  of this Note may not be sold or  transferred  unless  (i) they first
shall have been registered  under the Act and applicable  state securities laws,
(ii) the Borrower shall have been furnished with an opinion of legal counsel (in
form, substance and scope reasonably  acceptable to Borrower) to the effect that
such sale or transfer is exempt from the registration requirements of the Act or
(iii) they are sold  pursuant to Rule 144 under the Act.  Each  certificate  for
shares of common stock issuable upon  conversion of this Note that have not been
so registered  and that have not been sold pursuant to an exemption that permits
removal of the legend,  shall bear a legend substantially in the following form,
as appropriate:

          THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THE
          SECURITIES  HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE
          SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE
          REGISTRATION   STATEMENT  FOR  THE   SECURITIES   UNDER  THE
          SECURITIES ACT OF 1933, AS AMENDED, OR AN OPINION OF COUNSEL
          IN FORM,  SUBSTANCE AND SCOPE  REASONABLY  ACCEPTABLE TO THE
          BORROWER THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR
          UNLESS SOLD  PURSUANT  TO RULE 144 UNDER SAID ACT.  ANY SUCH
          SALE,   ASSIGNMENT   OR  TRANSFER   MUST  ALSO  COMPLY  WITH
          APPLICABLE STATE SECURITIES LAWS.

     Upon the request of a holder of a  certificate  representing  any shares of
common stock  issuable upon  conversion of this Note,  the Borrower shall remove
the  foregoing  legend  from  the  certificate  or  issue  to such  holder a new
certificate  therefor free of any transfer legend, if (i) with such request, the
Borrower  shall  have  received   either  an  opinion  of  counsel,   reasonably
satisfactory  to the Borrower in form,  substance and scope,  to the effect that
any such legend may be removed  from such  certificate,  or (ii) a  registration
statement under the Act covering such  securities is in effect.  Nothing in this
Note shall affect in any way the Holder's  obligations to comply with applicable
securities laws upon the resale of the securities referred to herein.

     Borrower agrees to use its best efforts to register with the Securities and
Exchange  Commission,  no later  than the end of the term of this  Note  (unless
legally  prohibited  from doing so), a number of shares of Common Stock equal to
the  principal  amount  of this  Note  outstanding  at the time of  registration
divided by the  Conversion  Price with  respect to  Borrower.  Such Common Stock
shall not be used, without permission from the Holder, for any other purposes.

     2.6 EFFECT OF MERGER, CONSOLIDATION,  ETC. If at any time when this Note is
issued and outstanding,  there shall be any merger,  consolidation,  exchange of
shares, recapitalization, reorganization, or other similar event, as a result of
which shares of Common Stock of the Borrower shall be changed into the same or a
different number of shares of another class or classes of stock or securities

                                       3
<PAGE>


of the Borrower or another  entity,  or in case of any sale or conveyance of all
or substantially all of the assets of the Borrower other than in connection with
a plan of complete  liquidation  of the  Borrower,  then the Holder of this Note
shall  thereafter  have the right to receive upon  conversion of this Note, upon
the bases and upon the terms and conditions  specified herein and in lieu of the
shares of Common Stock then issuable upon  conversion of this Note (assuming the
occurrence of the Amendments whether or not that has then occurred), such stock,
securities  or assets  which the Holder  would have been  entitled to receive in
such  transaction  had  this  Note  been  converted  immediately  prior  to such
transaction,  and in any such  case  appropriate  provisions  shall be made with
respect to the rights and  interests  of the Holder of this Note to the end that
the provisions hereof (including, without limitation,  provisions for adjustment
of the Conversion  Price and of the number of shares issuable upon conversion of
this Note) shall  thereafter be  applicable,  as nearly as may be practicable in
relation to any securities or assets  thereafter  deliverable  upon the exercise
hereof. The Borrower shall not effect any transaction  described in this Section
2.6 unless the  resulting  successor or acquiring  entity (if not the  Borrower)
assumes by written  instrument  the  obligations of this Section 2.6. The Holder
will have the right if a merger or consolidation  occurs to force the payment in
full of this Note.

     2.7 CONVERSION  AFTER EVENT OF DEFAULT.  The Holder's right to convert this
Note into stock as  described  above shall apply even if an Event of Default (as
defined in Article III below) shall have occurred.

                                   ARTICLE III

this  clause (ii) only,  such  failure  continues  for a period of five (5) days
after the due date thereof;

     3.2  CONVERSION.  The Borrower fails to issue shares of common stock to the
Holder  upon  exercise by the Holder of the  conversion  rights of the Holder in

uncured for five (5) business  days after the Borrower  shall have been notified
thereof in writing by the Holder;

     3.3 BREACH OF  COVENANT.  The Borrower  breaches  any material  covenant or
other  material  term or  condition  of this Note  (other  than as  specifically

of ten (10) business days after written  notice thereof to the Borrower from the
Holder;

     3.4  BREACH  OF  REPRESENTATIONS  AND  WARRANTIES.  Any  representation  or
warranty  of  the  Borrower  made  herein  or in  any  agreement,  statement  or
certificate given in writing pursuant hereto or in connection  herewith shall be
false or  misleading  in any material  respect when made and the breach of which
would have a material  adverse  effect on the  Borrower or the  prospects of the
Borrower or a material  adverse effect on the Holder or the rights of the Holder
with respect to this Note or the shares of common stock issuable upon conversion
of this Note;

     3.5  RECEIVER OR TRUSTEE.  The Borrower or any  subsidiary  of the Borrower

to by the Holder;

     3.7  BANKRUPTCY.  Bankruptcy,  insolvency,  reorganization  or  liquidation

Collateral  (as defined in Article IV hereof) in excess of  reasonably  expected

previously  or  hereafter  filed  reports  pursuant to the  requirements  of the
Securities  Exchange  Act of 1934,  as  amended,  or the rules  and  regulations
promulgated thereunder.

     Then,  upon the  occurrence  and  during the  continuation  of any Event of
Default specified in Sections 3.1, 3.2, 3.3, 3.4, 3.6, 3.8 or 3.9 hereof, at the
option of the Holder  hereof,  and upon the  occurrence  of any event of default
specified in Sections 3.5 or 3.7 hereof,  the Borrower  shall pay to the Holder,
in  satisfaction of its obligation to pay the  outstanding  principal  amount of
this Note and accrued and unpaid interest thereon, an amount equal to the sum of
(i) the  product  of (x) the then  outstanding  principal  amount  of this  Note
multiplied  by (y) 110% plus (ii)  accrued  and  unpaid  interest  on the unpaid
principal amount of this Note to the date of payment (the "Default  Amount") and
such Default Amount, together with all other ancillary amounts payable hereunder
shall  immediately  become due and payable,  all without demand,  presentment or
notice,  all of which  hereby are  expressly  waived,  together  with all costs,
including,  without limitation,  legal fees and expenses of collection,  and the
Holder shall be entitled to exercise all other rights and remedies  available at
law or in equity.

     If the Borrower  fails to pay the Default  Amount  within five (5) business
days of written  notice  that such  amount is due and  payable,  then the Holder
shall have the right at any time, so long as the Borrower remains in default, to
require the Borrower,  upon written notice,  to immediately issue (in accordance
with the terms of Article II hereof),  in lieu of the Default Amount, the number
of shares of Common Stock of the Borrower equal to the Default Amount divided by
the Conversion Price then in effect.

                                   ARTICLE IV

                                   COLLATERAL

     Borrower  hereby  grants to Holder a security  interest  in all  inventory,
machinery,  equipment,  stocks, bonds, notes, accounts receivable, any rights or
claims that they may have against any other  person,  firm, or  corporation  for
monies, choses in action, any bank accounts, checking accounts,  certificates of
deposit or any financial instrument, patents and intellectual property rights or
any  other  assets  owned  by  Borrower  as of the  date of this  agreement,  or
hereafter acquired.

     Borrower hereby represents that none of the collateral encumbered hereunder
has been sold or  assigned  since the  original  promissory  note of Borrower to
Holder  of  January  26,  1999 and that the lien of the  holder  of this note is
uninterrupted  from January 26, 1999 and shall  continue until this note is paid
or otherwise disposed of in accordance with its terms and conditions.

                                       5
<PAGE>


     All  collateral  rights in  intellectual  property is  subordinated  to the
Borrower's current licenses and future licenses  provided,  that with respect to
future  licenses,  the consent of the Holder must be obtained,  but such consent
will not be unreasonably  withheld.  The patents and intellectual property which
are licensed under the cross license  agreement dated September 27, 1997,  among
NXT plc, New Transducers Limited, being related companies,  the Borrower and NCT
Audio Products,  Inc. (or any successor  agreements) are  specifically  excluded
from the collateral.  There are approximately 20 pieces of intellectual property
in which,  under the cross license  agreement,  Borrower may not, and hence does
not herein, grant a security interest.  In addition,  all agreements between NCT
Audio  Products,  Inc. and the Borrower that relate to such  agreement,  and the
stock of NCT Audio  Products,  Inc.  owned by the Borrower,  shall  similarly be
excluded from the security interest granted in this Note.

     If Borrower does not pay the debt or other obligations under this Note when
due, the  collateral may be sold in order to pay such debt and  obligations,  or
same may be transferred  to the name of the Holder,  as Holder in her discretion
decides.  Holder may inspect the  collateral at all reasonable  times.  Borrower
further agrees that it will do anything reasonably  requested by Holder in order
to make Holder's security interest in the collateral legally effective including
the execution of a UCC-1.

                                    ARTICLE V

                                  MISCELLANEOUS

5.1   FAILURE OR INDULGENCY  NOT WAIVER.  No failure or delay on the part of the
Holder in the exercise of any power, right or privilege  hereunder shall operate
as a waiver thereof, nor shall any single or partial exercise of any such power,
right or privilege  preclude other or further  exercise  thereof or of any other
right,  power or  privilege.  All rights and  remedies  existing  hereunder  are
cumulative to, and not exclusive of, any rights or remedies otherwise available.

5.2   NOTICES.  Notices, demands and other communications  given under this Note
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:
