This CONSULTING AGREEMENT (this "Agreement") is entered into this
28th day of June,  1996,  by and  between ATC  Capital  Group  Ltd.,  a Delaware
corporation ("ATC"), and Chris F. Brown ("Consultant").

                              W I T N E S S E T H :

               WHEREAS, ATC recently acquired two licenses to exploit throughout
the world certain  technology for use on open  networks,  including the Internet
(the "Licenses");

               WHEREAS,  Consultant  rendered certain consulting services to ATC
in connection with the acquisition of the Licenses and is willing to continue to
provide consulting services to ATC on the terms and conditions set forth herein;
and

               WHEREAS,  ATC desires to compensate  Consultant  for his services
rendered  to date and to engage  Consultant  to  provide  additional  consulting
services on the terms and conditions set forth herein,

               NOW,  THEREFORE,  in  consideration  of the mutual  promises  and
covenants contained herein, the parties hereto agree as follows:

               1. ATC hereby engages Consultant on a non-exclusive basis for the
term  specified in this  Agreement to render advice and services as a consultant
to ATC regarding the establishment of strategic  alliances  throughout the world
with banks,  telecommunications companies, credit card issuers and other related
Internet software providers,  which services shall also include, when Consultant
shall deem appropriate and feasible,  introductions to the foregoing. Consultant
shall  provide such  services and shall devote such time and attention as in the
consultant's  reasonable  discretion  may be  necessary  or  desirable  for  the
performance of his duties hereunder as a consultant when called upon to do so by
ATC,  provided  that (i) ATC shall not  require  that  Consultant's  services be
performed  at  any  particular  place  or at any  particular  time,  (ii)  it is
expressly understood and agreed that Consultant's services are of great value to
ATC by  reason of the  Consultant's  prior  experience  and  knowledge  and that
telephonic  advice and  judgements of Consultant  are as valuable to ATC and its
subsidiaries as written reports or physical  attendance at any particular  place
or at any  particular  time,  and (iii) in no event shall Consult be required to
devote  more  than ten (10)  hours per  month to the to the  performance  of his
services hereunder.

               2.  Consultant  may  employ  sub-contractors  who are  individual
persons to assist in his  duties,  and may assign a portion of his  compensation
hereunder to such sub-contractors, provided such assignment is made prior to the
filing  of the  registration  statement  on Form S-8  referred  to in  Section 7
hereof.

               3. The term of Consultant's  engagement  hereunder shall commence
on the date hereof and shall terminate 90 days thereafter.







               4. In consideration for all of the services  heretofore  rendered
by Consultant's in connection with the Licenses and to be rendered  hereunder by
Consultant,  ATC hereby agrees to issue to  Consultant,  and  Consultant  hereby
agrees to accept as full payment, (i) 500,000 shares (the "Shares") of par value
$.0002 per share (the "Common  Stock");  and (ii) a warrant (the  "Warrant")  to
purchase 500,000 shares of ATC's Common Stock, at an exercise price of $4.50 per
share,  exercisable  at any time and from time to time after  issuance until the
second  anniversary  thereof.  The  Shares and  Warrant  shall be  delivered  to
Consultant as soon as practicable following the execution of this Agreement.

               5. Subject to the provisions of Section 7 hereof, the Shares, the
Warrant and the shares of Common  Stock  issuable  upon  exercise of the Warrant
(the "Underlying Shares") will not have been registered under the Securities Act
of 1933,  as amended  (the  "Act")  and may not be  offered,  sold or  otherwise
transferred  unless  registered  under  the  Act  or  pursuant  to an  available
exemption.  The certificates  representing the Shares and the Underlying  Shares
and the Warrant will contain the customary restrictive legend.

               6.  Notwithstanding  anything to the contrary  contained  herein,
Consultant agrees that during each ninety (90) day period commencing on the date
hereof,  he will not offer for sale or sell (which shall exclude any  assignment
as provided in Section 2 hereof) more than an aggregate of 25% of the Shares and
25% of the Underlying Shares plus any amount of the Shares and Underlying Shares
that  Consultant  was  permitted  hereunder  to sell during the prior ninety day
period or periods but had not yet sold. If Consultant shall have assigned any of
his  compensation  hereunder  as  permitted  under  Section 2  hereof,  then the
foregoing  restrictions shall apply to sales made or to be made in the aggregate
by Consultant and such assignee(s).

               7. On or before August 1, 1996, ATC agrees, subject to applicable
law,  to file  with  the  Securities  and  Exchange  Commission  a  registration
statement  on Form S-8 so as to permit the  public  offer and sale of the Shares
and the  Underlying  Shares.  ATC will not be  required  to take any action with
respect to or make any filing under state "Blue sky" laws.

               8.  The  parties  hereto  intend  that   Consultant  will  be  an
independent  contractor  and  not an  employee  of  ATC.  Therefore  none of the
benefits  that may be provided by ATC to its employees  shall be available  from
ATC to  Consultant.  The  parties  understand  that  it  shall  be  Consultant's
responsibility  to  provide  for all  unemployment  and other  taxes,  including
withholding and social security,  and all estimated taxes, business licenses and
insurance  (including  worker's  compensation  insurance  and  public  liability
insurance) arising out of or relating to this agreement.

               9. Any notices or other  communications  or documents to be given
or  permitted  hereunder  to any party  shall be  mailed  first  class,  postage
prepaid, and if to ATC addressed to:

               10.  If  anyone  or  more  of the  provisions  contained  in this
Agreement  shall,  for any reason,  be expressly held to be invalid,  illegal or
unenforceable in any respect,  such invalidity,  illegality or  unenforceability
shall not affect any other  provisions  of this  Agreement,  and this  Agreement
shall be construed as if such invalid,  illegal or  unenforceable  provision had
never been contained herein.

               11. This Agreement shall be binding on Consultant's  heirs, legal
representatives  and assigns,  and shall inure to the benefit of any  successors
and assigns of ATC.

               12. Any waiver of a right under or breach of a provision  of this
Agreement shall not be a waiver or any other rights or subsequent  breach of the
same or other provisions of this Agreement.
