corporation  ("NCT"),  (ii)  the  holders  of  Series A  Preferred  Stock of NCT

                                    RECITALS

     A. In connection  with the proposed  issuance of Series A Preferred  Stock,
par value $0.10 per share (the "Preferred Stock") of the Company for the benefit
of Teltran  International  Group,  Ltd., a Delaware  corporation,  pursuant to a
Stock and  Asset  Purchase  Agreement  dated  January  24,  2001 (the  "Purchase
Agreement"),  the parties hereto would like to accommodate  their  interests and
relationship in the matters as set forth in the Purchase  Agreement with respect
to the holding, voting, acquisition and transfer by the Stockholders (as defined
below) of the  Preferred  Stock and the common stock of the  Company,  par value
$0.001 per share (the "Common Stock")  issuable upon conversion of the Preferred
Stock (the "Restricted  Common" and  collectively  with the Preferred Stock, the
"Covered  Securities").  The Company and the signatories hereto intend and agree
that this  Agreement  shall become  effective  and be binding upon them upon the
closing of the Purchase Agreement.

     B. All terms not defined  herein,  shall have the meanings set forth in the
Purchase Agreement and the Certificate of Designations (as defined below).

                                    AGREEMENT

     NOW, THEREFORE,  in consideration of the foregoing,  of the mutual promises
hereinafter set forth, and of other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the parties agree as follows:

     1.  Application to Stockholders.  For purposes of this Agreement,  the term
"Stockholders"  as used herein  shall mean (i) the Series A Holders and (ii) any
successors or assigns thereof that receive Covered Securities other than through
transfers on a Principal Market.

     2. Voting of Restricted Common. Each Stockholder shall cause the Restricted
Common to be voted at any meeting of the  stockholders of the Company or, in any
consent in lieu of such a meeting,  as recommended by a majority of the Board of
Directors of the Company to the common  stockholders  of the Company,  including
with respect to the election of Directors.

     3. Standstill Agreement.  The Stockholders covenant and agree that, without
the prior  written  consent of the Board of  Directors  of the Company and other
than with respect to the  conversion of the Preferred  Stock,  the  Stockholders
shall not, directly or indirectly, alone or through or with others: (a) acquire,
offer to acquire,  or agree to acquire,  directly or indirectly,  by purchase or
otherwise, any securities or direct or indirect rights to acquire any securities
of the Company,  or any successor to or person in control of the Company, or any
subsidiary or division  thereof or of any such successor or controlling  person;
(b)  make,  or  in  any  way  participate,   directly  or  indirectly,   in  any
"solicitation"  of "proxies" to vote (as such terms are used in the rules of the
U.S. Securities and Exchange Commission ("SEC")), or seek to advise or influence
any person or entity with respect to the voting of any voting  securities of the
Company,  or seek to  influence  or control the  policies or  management  of the
Company  or  any  subsidiary  or  a  division  thereof;   (c)  make  any  public
announcement  with  respect  to a proposal  for,  or submit an offer of (with or
without conditions), any extraordinary transaction involving the Company, any of
its  subsidiaries  or  divisions  or of any of their  respective  securities  or
assets;  (d) form,  join or in any way  participate  in a "group"  as defined in
Section 13(d)(3) of the Securities  Exchange Act of 1934, as amended  ("Exchange
Act"), in connection with any of the foregoing; (e) publicly request the Company
or any of its  Representatives,  directly  or  directly,  to amend or waive  any
provision of this paragraph;  or (f) enter into any  discussions,  negotiations,
arrangements or  understandings  with any third party with respect to any of the
foregoing.  The  references  in this  paragraph  to the rules of the SEC and the
Exchange Act shall apply for all purposes  under this  Agreement  whether or not
the  Company  has  registered  a class of  securities  under  Section  12 of the
Exchange Act.

     As used in this  Agreement,  the  term  "Representative"  means,  as to any
person,  such person's  subsidiaries  and other  affiliates  and its, his or her
directors,  officers, employees,  partners, agents, advisors (including, without
limitation,   financial  advisors,  counsel  and  accountants)  and  controlling
persons, and the term "person" shall be broadly interpreted to include,  without
limitation, any corporation, company, partnership or other entity or individual.

     4. Private  Transactions.  Nothing herein shall restrict a Stockholder from
selling,  transferring or otherwise  disposing of any Covered  Securities in any
privately negotiated  transactions,  provided that the purchaser,  transferee or
other  successor or assignee of such  Stockholder  execute and deliver a copy of
this  Agreement  to the  Company  as a  signatory  hereto.  Any person or entity
acquiring Covered  Securities in any privately  negotiated  transaction shall be
deemed a successor of a Stockholder  for purposes of this Section 4 whether as a
direct, indirect or multiple successor of such Stockholder.

     5. Principal Market Transactions.  Notwithstanding anything to the contrary
in this  Agreement,  the  Stockholders  are  permitted  to transfer  (an "Exempt
Transfer") Restricted Common in transactions negotiated through and reported on,
any  Principal  Market  in  accordance  with  the  terms of the  Certificate  of
Designations, Preferences and Rights of Series A Convertibles Preferred Stock of
the Company as filed with the  Delaware  Secretary of State on February 23, 2001
(the "Certificate of Designations").  The term "Principal Market" as used herein
shall mean any  exchange or other  market for the trading of  securities  by the
public anywhere in the world,  and as to which the Company has listed its Common
Stock for trading.

     6.  Legends;  Removal.  To assist in  effectuating  the  provisions of this
Agreement,  certificates  for all Covered  Securities  will  contain a legend to
reflect  that  such  shares  of the  Covered  Securities  are  subject  to  this
Agreement,  which shall remain  thereon until such shares of  Restricted  Common
have been sold,  transferred,  or disposed of in an Exempt Transfer. The Company
shall deliver, or cause its Transfer Agent to deliver,  unlegended  certificates
for shares of  Restricted  Common to a Stockholder  or its designees  within the
settlement  period for  transactions  in securities  on any Principal  Market on
which such  shares of  Restricted  Common  have been sold or  transferred  in an
Exempt  Transfer,  upon receipt from the  Stockholder  or its  broker-dealer  of
written  confirmation  that the sale or transfer  of such  shares of  Restricted
Common was conducted in accordance  with the rules,  regulations  and applicable
laws of such Principal Market.

     7.  Termination of Agreement.  This Agreement shall be in effect until such
time when all shares of  Restricted  Common  held by the  Stockholders  or their
successors and assigns have been transferred through an Exempt Transfer.

     8. Special Remedy and Specific Performance.

     (a) In the event of a Breach (as hereinafter defined),  the Company may, at
its option,  purchase (or, at its option,  cause a Representative  designated by
the  Company  to  purchase)  any  number  of shares of  Restricted  Common  then
beneficially  owned,  directly or indirectly,  by the Stockholder in Breach at a
price  per  share  equal to the  average  final  trading  price (or if the final
trading  price is not  available,  the  final  bid  price)  as  reported  on the
Principal  Market,  by Bloomberg (or if applicable  the London SEATS System) for
the five consecutive  trading days ending the last trading day before the Breach
Date (as  hereinafter  defined)  (or if the Common  Stock did not trade for five
consecutive  days on the  Principal  Market,  the five most recent  trading days
prior to the Breach Date);  such purchase to be effected within 30 calendar days
following  the Breach  Date.  If the Common  Stock is listed for trading on more
than one Principal  Market,  the  determination  of the price per share shall be
based upon the Principal  Market that reported the highest average daily trading
volume for the period from the date the Common  Stock was  initially  listed for
trading on any  Principal  Market  through  the Breach  Date.  The  Company  may
purchase  such shares for, at the  Company's  option,  cash, a  promissory  note
having a maturity  date no later  than one year  following  the Breach  Date and
carrying  simple  interest  on  principal  at a per  annum  rate  of 9%,  or any
combination  thereof.  The term  "Breach"  means any  material  violation of any
provisions  of  paragraph 2 or paragraph 3 of this  Agreement.  The term "Breach
Date" means the date on which the Company  properly  gives written notice to the
Stockholder of a violation  which  constitutes a Breach.  The right contained in
this  subparagraph  8(a)  shall not be deemed to be the  exclusive  remedy for a
breach of this  Agreement,  it being  understood  that such  right  shall not be
deemed to prejudice, or to operate as a waiver of, any other remedy contained in
this  Agreement  or any other remedy to which the Company may be entitled at law
or in equity.

     (b) The  Stockholders  acknowledge  and  agree  that  the  Company  and its
stockholders would be irreparably injured in the event that any provision of the
Agreement is breached or not performed by the  Stockholders  in accordance  with
their  specific  terms.  Accordingly,  it is  agreed  that each  party  shall be
entitled to temporary and permanent  injunctive  relief with respect to each and
any  breach  or  purported  repudiation  of this  Agreement  by the other and to
specifically  enforce  strict  adherence  to this  Agreement  and the  terms and
provisions  hereof  against  the other in any  action  instituted  in a court of
competent  jurisdiction,  in addition to any other remedy  which such  aggrieved
party may be entitled to obtain.  Moreover, in the event of the breach of any of
the  provisions  of this  Agreement,  timeliness  in obtaining  relief is of the
essence.

     9. Amendments;  Waiver of Terms. Neither this Agreement nor any term hereof
may be changed,  waived,  discharged or terminated orally or in writing,  except
that any term of this  Agreement  may be  amended  by a  writing  signed  by the
parties,  and the observance of any such term may be waived (either generally or
in a particular instance and either retroactively or prospectively)  solely by a
writing signed by the party against whom such waiver is to be asserted.
