EXCHANGE RIGHTS AGREEMENT
                                     (Notes)


     This  Agreement is dated as of the 29th day of June,  2001 among NCT Group,
Inc., a Delaware  corporation  (the  "Company"),  and the Holders  identified on
Schedule A hereto (individually a "Holder", collectively the "Holders").

     WHEREAS,  Artera  Group,  Inc., a Delaware  corporation,  is a wholly owned
subsidiary of the Company ("Subsidiary"); and

     WHEREAS,  the Holders are purchasing pursuant to that certain  Subscription
Agreement  dated at or about June 29, 2001 between the Holder and the Subsidiary
(the  "Subscription   Agreement")  convertible  notes  of  the  Subsidiary  (the
"Notes"),  the terms of which  are set  forth in the Notes and the  Subscription
Agreement,  (the  principal  amounts of the Notes  issued to the Holders are set
forth on Schedule A hereto); and

     WHEREAS  it is in the best  interests  of the  Company  for the  Holders to
purchase  the  Notes  and as an  inducement  therefore  and for  other  good and
valuable  consideration,  the  receipt  of which is hereby  acknowledged  by the
Company,  the Company hereby grants the exchange rights  described herein to the
Holders.

     NOW THEREFORE, the parties agree as follows:

     1. Exchange into the Company's Common Stock.

     (a) The Holder shall have the right (such a right an "Exchange Right") from
November 30, 2001, and at any time  thereafter  that Notes are  outstanding,  to
exchange  any  outstanding  Note  principal  and  interest  for  fully  paid and
nonassessable shares of the Company's common stock, par value $.01 per share, as
such stock exists on the date of issuance of the Notes, or any shares of capital
stock  of  Company  into  which  such  stock  shall   hereafter  be  changed  or
reclassified  (the "Common  Stock") at the exchange  price as defined in Section
1(b) hereof (the "Exchange Price"), determined as provided herein. The number of
shares of Common  Stock to be issued  upon each  exchange  of the Notes shall be
determined  by  dividing  the  principal  of that  portion  of the  Notes  to be
exchanged, by the Exchange Price.

     (b) Subject to  adjustment  as provided in Section 4 hereof,  the  exchange
price per share (the  "Exchange  Price") shall be one hundred  percent (100%) of
the  average of the  closing  bid  prices  for the Common  Stock on the OTC Pink
Sheets, NASD OTC Bulletin Board, NASDAQ SmallCap Market,  NASDAQ National Market
System,  American Stock Exchange, or New York Stock Exchange, as applicable,  or
if not then  trading on any of the  foregoing,  such other  principal  market or
exchange where the Common Stock is listed or traded  (whichever of the foregoing
is at the time the  principal  trading  exchange or market for the Common Stock,
the  "Principal  Market"),  for the  five  (5)  trading  days  prior  to but not
including the Exchange Date.

     2. (a)  Exchange  Procedure.  The Holder of Notes  desiring to exchange any
principal  or  interest  portion  of such Notes may give  written  notice of its
decision to exchange the Notes for Common Stock by delivering or  telecopying an
executed  and  completed  notice of exchange in the form  annexed  hereto  (such
notice a "Notice of  Exchange") to the Company (any date of giving such a Notice
of Exchange,  an "Exchange  Date") and  delivering  within three  business  days
thereafter,  the  original  Note to the Company.  The Company will  transmit the
certificates  representing  the shares of Common Stock issuable upon exchange of
Notes  (together  with a Note  representing  the Note principal and interest not
exchanged)  to the  Holder  via  express  courier,  by  electronic  transfer  or
otherwise for receipt by the Holder, within five (5) business days after receipt
by the Company of the original or telecopied  Notice of Exchange and thereafter,
the Note to be  exchanged  (the  "Delivery  Date").  The  Holder  of the Note so
surrendered  for exchange shall be entitled to receive on or before the Delivery
Date a certificate or certificates  which shall be fully paid and non-assessable
for the number of shares of Common  Stock to which such Holder shall be entitled
upon such  exchange,  registered in the name of such Holder.  In the case of any
Note which is exchanged  only in part,  the Holder of a Note shall upon delivery
of the certificate or certificates  representing Common Stock also receive a new
Note representing the unexchanged portion of the Note.

     (b) The Company shall not be required,  in connection  with any exchange of
Notes,  to issue a  fraction  of a share of its Common  Stock and shall  instead
deliver a stock certificate representing the next whole number.

     3.  Exchange  Limitations.  The Holder may not exchange  that amount of the
Note on an Exchange  Date into  amounts of Common Stock which would be in excess
of the sum of (i) the number of shares of Common Stock beneficially owned by the
Holder and its  affiliates on such Exchange  Date, and (ii) the number of shares
of Common Stock issuable upon the exchange of the Note with respect to which the
determination  of this proviso is being made on such Exchange Date,  which would
result in  beneficial  ownership by the Holder and its  affiliates  of more than
9.99% of the outstanding shares of Common Stock of the Company. For the purposes
of the proviso to the immediately preceding sentence, beneficial ownership shall
be determined in accordance with Section 13(d) of the Securities Exchange Act of
1934, as amended (the "Exchange  Act"), and Rule 13d-3  promulgated  thereunder.
The Holder may revoke the exchange limitation described in this Paragraph 3 upon
75 days prior notice to the Company. The Holder may allocate which of the equity
of the Company deemed  beneficially owned by the Holder shall be included in the
9.99%  amount  described  above and which shall be allocated to the excess above
9.99%.

     4. Merger/Sale of Assets/Dividends.

     (a) In case of any  merger of the  Company  with or into any other  Company
(other than a merger in which the Company is the surviving or continuing Company
and which does not result in any  reclassification,  exchange,  or change of the
outstanding  shares of Common  Stock) then  unless the right to  exchange  Notes
shall have  terminated,  as part of such merger  provision shall be made so that
Holders of Notes shall  thereafter have the right to exchange Notes held by such
Holder into the kind and amount of shares of stock  and/or other  securities  or
property  receivable  upon such  merger  by a holder of the  number of shares of
Common Stock into which such Notes might have been exchanged  immediately  prior
to such  consolidation or merger.  The foregoing  provisions of this Paragraph 4
shall similarly apply to successive mergers.

     (b) In case of any sale or  conveyance  to another  person or entity of the
property of the Company as an entirety,  or  substantially  as an  entirety,  in
connection with which shares or other securities or cash or other property shall
be issuable,  distributable,  payable,  or deliverable for outstanding shares of
Common  Stock,  then,  unless  the  right  to  exchange  the  Notes  shall  have
terminated,  lawful  provision  shall be made so that the Holders of Notes shall
thereafter  have the right to  exchange  the Notes  into the kind and  amount of
shares  of  stock  or other  securities  or  property  that  shall be  issuable,
distributable, payable, or deliverable upon such sale or conveyance with respect
to each share of Common Stock immediately prior to such conveyance.

     (c) If the shares of Common Stock are subdivided or combined into a greater
or smaller  number of shares of Common  Stock,  or if a dividend  is paid on the
Common  Stock  in  shares  of  Common  Stock,   the  Exchange   Price  shall  be
proportionately  reduced in case of  subdivision  of shares or stock dividend or
proportionately  increased in the case of  combination  of shares,  in each such
case by the ratio which the total number of shares of Common  Stock  outstanding
immediately after such event bears to the total number of shares of Common Stock
outstanding immediately prior to such event.

     (d) In case at any time the Company shall propose:

     (i) to pay any dividend or  distribution  payable in shares upon its Common
Stock or make any distribution (other than cash dividends) to the holders of its
Common Stock; or

     (ii) to offer for  subscription  to the  holders  of its  Common  Stock any
additional shares of any class or any other rights; or

     (iii) any capital  reorganization or  reclassification of its shares or the
merger of the Company  with  another  Company  (other than a merger in which the
Company is the surviving or continuing  Company and which does not result in any
reclassification,  exchange,  or  change  of the  outstanding  shares  of Common
Stock); or

     (iv) the voluntary dissolution, liquidation or winding-up of the Company;

then,  and in any one or more of said cases,  the  Company  shall cause at least
fifteen (15) days prior notice of the date on which (A) the books of the Company
shall  close or a record  be taken for such  stock  dividend,  distribution,  or
subscription  rights,  or (B)  such  capital  reorganization,  reclassification,
merger, dissolution, liquidation or winding-up shall take place, as the case may
be, to be mailed to the Holders of Notes.

     (e) The  Company  shall pay the amount of any and all issue  taxes (but not
income  taxes) which may be imposed in respect of any issue or delivery of stock
upon the exchange of a Note, but all transfer taxes and income taxes that may be
payable  in  respect  of  any  change  of  ownership  of a Note  or  any  rights
represented  thereby or of stock  receivable upon exchange thereof shall be paid
by the person or persons surrendering such stock for exchange.

     (f) Whenever  the number of shares to be issued upon  exchange of the Notes
is required to be adjusted as provided in this  Paragraph  4, the Company  shall
forthwith compute the adjusted number of shares to be so issued and the adjusted
Exchange  Price and prepare a certificate  setting forth such adjusted  exchange
amount and the facts upon which such adjustment is based,  and such  certificate
shall forthwith be delivered to each Holder of Notes.

     5. Liquidated Damages.

     (a) In the  event a Holder  shall  elect  to  exchange  a Note as  provided
herein,  the Company may not refuse exchange based on any claim that such Holder
or any one  associated  or  affiliated  with such Holder has been engaged in any
violation  of law,  or for  breach  of this  Agreement  or any of the  agreement
between the Company and its  affiliates and the Holders,  unless,  an injunction
from a court, on notice, restraining and or enjoining exchange of all or part of
said Note shall have been  issued and the  Company  posts a surety  bond for the
benefit of such  Holder in the amount of 125% of the  principal  of the Note and
accrued  interest  sought to be exchanged,  which is subject to the  injunction,
which bond shall remain in effect until the completion of arbitration/litigation
of the dispute and the  proceeds of which shall be payable to such Holder in the
event it obtains judgment.

     (b) Intentionally Omitted.

     (c) Intentionally Omitted.

     (d) In the event (i) the Company is prohibited  from issuing  Common Stock;
(ii) fails to timely  deliver  Common  Stock within five  business  days after a
Delivery  Date;  (iii) if the  Approval  (as defined in Section 6 hereof) is not
obtained on or before July 10, 2001; or (iv) if the Required Reserve (as defined
in  Section 6 hereof) is not set aside and  reserved  on behalf of the holder of
the Note on or before July 10, 2001, then at the Holder's election,  the Company
must pay to the Holder five (5) business  days after request by the Holder or on
the Delivery  Date (if requested by the Holder) a sum of money equal to the Note
principal  designated by the Holder  together  with accrued but unpaid  interest
thereon ("Mandatory Redemption Payment").  The Mandatory Redemption Payment must
be  received  by the  Holder  on the same  date as the  Common  Stock  otherwise
deliverable or within five (5) business days after request,  whichever is sooner
("Mandatory  Redemption Payment Date"). Upon receipt of the Mandatory Redemption
Payment,  the  corresponding  Note  principal  will be deemed paid and no longer
outstanding.

     (e) In the event the Common Stock  issuable upon exchange of a Note or part
thereof is not included for resale in an effective registration statement at any
time when such Common Stock is required to be so included  pursuant to the terms
of  this  Agreement,  and  the  Registration  Rights  Agreement  referred  to in
Paragraph 7 below,  then the Holder may elect, at the Holder's sole  discretion,
to receive an amount of  restricted  Common  Stock equal to the amount of Common
Stock  otherwise  receivable upon exchange in lieu of the Common Stock otherwise
receivable pursuant to the relevant Notice of Exchange.

     (f)  Nothing  contained  herein or in any  document  referred  to herein or
delivered  in  connection  herewith  shall be deemed to establish or require the
payment  of a rate of  interest  or  other  charges  in  excess  of the  maximum
permitted by applicable law. In the event that the rate of interest or dividends
required to be paid or other charges  hereunder exceed the maximum  permitted by
such law,  any  payments in excess of such  maximum  shall be  credited  against
amounts owed by the Company to the Holder and thus refunded to the Company.

     6.  Undertaking/Share  Reservation.  So  long  as any  Notes  shall  remain
outstanding  and the Holders  thereof shall have the right to exchange same, the
Company shall at all times reserve from the  authorized  and unissued  shares of
its Common  Stock a  sufficient  number of shares to provide for such  exchanges
subject to the  following:  The  Company  will  reserve  the number of shares of
Common  Stock on behalf of each  Holder of a Note equal at all times to not less
than 130% of the  amount of Common  Stock  necessary  to allow  exchange  of the
entire Note principal and accrued interest.  To the extent that the Company does
not have sufficient authorized and unissued shares of Common Stock available for
full  exchange  of the Note,  the  Company  shall seek  shareholder  approval to
increase  the number of  authorized  shares of Common  Stock to provide  for the
reservation  of the number of shares of Common Stock equal to not less than 130%
of the number of shares of Common Stock that would be issuable  upon exchange of
the Note employing the lowest Exchange Price in effect at any time from the date
of this  Agreement  and until  the date  immediately  preceding  the date of the
meeting of the  Company's  shareholders  at which such  approval is sought (such
amount being the "Required  Reserve" and the  shareholder's  approval  being the
"Approval").  The Company  undertakes  to obtain the Approval no later than July
10, 2001 and reserve the Required Reserve.

     7. Registration  Rights.  The Holder has been granted certain  registration
rights by the Company in connection  with the Common Stock.  These  registration
rights are set forth in a  Registration  Rights  Agreement  entered  into by the
Company and Holder at or about the date of this Agreement.

     8. Indemnification.

     (a) The Company agrees to indemnify,  hold  harmless,  reimburse and defend
Holder, Holder's officers,  directors, agents, affiliates,  control persons, and
principal shareholders, against any claim, cost, expense, liability, obligation,
loss or damage (including  reasonable legal fees) of any nature,  incurred by or
imposed upon Holder or any such person which results,  arises out of or is based
upon (i) any  misrepresentation  by Company or breach of any warranty by Company
in this  Agreement  or in any Exhibits or Schedules  attached  hereto,  or other
agreement  delivered pursuant hereto; or (ii) after any applicable notice and/or
cure  periods,  any  breach or  default  in  performance  by the  Company of any
covenant or undertaking to be performed by the Company  hereunder,  or any other
agreement entered into by the Company and Holders relating hereto.

     (b) Holder agrees to  indemnify,  hold  harmless,  reimburse and defend the
Company and the  Company's  officers  and  directors  against  any claim,  cost,
expense, liability, obligation, loss or damage (including reasonable legal fees)
of any nature,  incurred by or imposed upon the Company or any such person which
results,  arises out of or is based upon (i) any  misrepresentation by Holder or
breach  by  Holder of any  warranty  in this  Agreement  or in any  Exhibits  or
Schedules attached hereto or other agreement  delivered pursuant hereto; or (ii)
after any  applicable  notice  and/or  cure  periods,  any  breach or default in
performance  by Holder of any covenant or  undertaking to be performed by Holder
hereunder,  or any other  agreement  entered  into by the  Company  and  Holders
relating hereto.

     9. Miscellaneous.

     (a) Notices.  All notices or other  communications  given or made hereunder
shall be in writing and shall be  personally  delivered or deemed  delivered the

section shall be made pursuant to the provisions of this section.

     (b) Entire  Agreement;  Assignment.  This  Agreement  represents the entire
agreement  between the parties  hereto with respect to the subject matter hereof
and may be  amended  only by a writing  executed  by both  parties.  No right or
obligation  of either party shall be assigned by that party without prior notice

jurisdiction of such courts and waive trial by jury. The prevailing  party shall
be entitled to recover from the other party its reasonable  attorney's  fees and
costs.  In the event that any provision of this Agreement or any other agreement
delivered  in  connection   herewith  is  invalid  or  unenforceable  under  any
applicable  statute  or  rule  of law,  then  such  provision  shall  be  deemed
inoperative  to the extent that it may  conflict  therewith  and shall be deemed
modified to conform with such statute or rule of law. Any such  provision  which

or enforceability of any other provision of any agreement.

     (e) Specific Enforcement,  Consent to Jurisdiction.  The Company and Holder
acknowledge and agree that irreparable  damage would occur in the event that any

breaches of the  provisions of this  Agreement and to enforce  specifically  the
terms and  provisions  hereof or  thereof,  this being in  addition to any other
remedy to which any of them may be entitled by law or equity. Subject to Section
9(d) hereof,  each of the Company and Holder  hereby  waives,  and agrees not to
assert  in any  such  suit,  action  or  proceeding,  any  claim  that it is not
personally  subject to the jurisdiction of such court,  that the suit, action or
proceeding  is brought in an  inconvenient  forum or that the venue of the suit,
action or proceeding is improper.  Nothing in this Section shall affect or limit
any right to serve process in any other manner permitted by law.


     IN WITNESS  WHEREOF,  the parties  hereto have caused this Exchange  Rights
Agreement to be executed by the undersigned,  thereunto duly  authorized,  as of
the date first set forth above.
