         This  Assignment of License  Agreement (the  "Agreement") is made as of
the 15th day of June,  1993 among  NETWORK  LICENSING,  INC.,  a North  Carolina
corporation  having its  principal  place of business  at 3101/2  West  Franklin
Street,  Chapel  Hill,  North  Carolina,   27516  (hereinafter  referred  to  as
"Network");  MICHAEL R. JONES,  an individual  residing at 233 Palmer Hill Road,
Old Greenwich,  Connecticut,  06870  (hereinafter  referred to as "Jones");  and
GERALD  SINGER,  an individual  using an address of 3142 Pacific Coast  Highway,
Torrance,  California,  90505 and ARTHUR J. MURPHY,  an  individual  residing at
18337 Superior Street, Northridge,  California,  91324 (hereinafter collectively
referred to as "Licensor").

         WHEREAS,  Jones and  Licensor  have  entered  into an  agreement  dated
December 31, 1990  relating to U.S.  Patents Nos.  4,554,446  and  4,672,377 and
improvements thereon, (including but not limited to any patent that may issue on
U.S.  Application  Serial No.  07/856- 250, filed March 25, 1992, or any foreign
patent that application  thereon), a copy of which is attached hereto as Exhibit
A (the "License Agreement"),  and an addendum,  which may be executed, a copy of
which is attached hereto as Exhibit B ( the "Addendum")  (collectively  referred
to as the "New License Agreement"); and

         WHEREAS,  Network is desirous of an  assignment of all of Jones' rights
under the License Agreement;

         NOW, THEREFORE, the parties agree as follows:

         1. The license  previously granted to Jones by Licensor pursuant to the
License Agreement is hereby irrevocably assigned to Network.

         2. Network hereby assumes  responsibility for the fulfillment of all of
the terms and conditions of the License Agreement unless such terms are modified
in writing






         signed by Licensor and Network.
                  3. Licensor  hereby  consents to and accepts the assignment of
         the License Agreement to Network by Jones and agrees that Network shall
         have the benefit of all the provisions thereof to the same extent as if
         it  were  an  original  signatory  thereto  and  were  defined  as  the
         "Licensee"  as that term is used  therein.  Jones shall have no further
         obligation  or  liability  of any kind to  Licensor  under the  License
         Agreement, including, without limitation, any obligation,  liability or
         responsibility  pursuant to Section E of the License Agreement,  except
         that  obligation to Licensor  under that agreement  attached  hereto as
         Exhibit C.  Licensor  acknowledges  that as of May 1,  1993,  they have
         credited Jones with Two Hundred Forty-Four  Thousand Dollars ($244,000)
         of the Five Hundred Thousand ($500,000) referred to in Section B of the
         License  Agreement  in  connection  with the  reduction  of the royalty
         thereunder.  Jones and Licensor each warrants and  represents  that the
         License  Agreement is a valid and binding  obligation of said party and
         is in full force and effect as of the  execution of this  Agreement and
         agrees to waive any right he or they may have to terminate  the License
         Agreement pursuant to Section D of the License Agreement based upon any
         action or failure to act by any party thereto prior to the date hereof.
                  4. Except as otherwise  specifically  provided herein,  Jones'
         only remaining  obligation or privilege under the New License Agreement
         will be that,  should a default in the License  Agreement by Network be
         alleged,  Jones and Network shall  promptly be so notified by Licensor.
         If a default by Network,  including,  without  limitation,  any default
         arising  with  respect  to a  breach  of  Section  D4  of  the  License
         Agreement,  is 

                                       2




         determined  to exist and is not timely  cured by Network  such that the
         license  granted by the  Licensor  under the New License  Agreement  is
         terminated, then upon such termination and subject to Jones curing such
         default  the  Licensor  shall  immediately  grant a  license  to  Jones
         identical to that of the License Agreement,  as modified by the changes
         made by Paragraph 6 hereof.  
                   5. The term of this Agreement shall be the
         same as that of the License Agreement subject to the following:  (a) If
         the term of the  License  Agreement  is reduced  without the consent of
         Jones,  the  term of  this  Agreement  shall  not be  affected  by such
         modification  of the term of the License  Agreement and shall  continue
         for the term as set forth in the License Agreement;  and (b) if the New
         License  Agreement  is  terminated  because  all the  patents  licensed
         thereunder are determined to be invalid or  unenforceable by a court of
         competent  jurisdiction,  after all applicable appeals,  this Agreement
         shall have a term of five (5) years from the date of the final judgment
         with respect to said appeals,  if such determination is the result of a
         challenge by Network, its successors, assigns, sublicensees or directly
         or indirectly by any of its  shareholders,  this Agreement shall have a
         term of fifteen  (15) years from the date of such final  determination;
         provided,  however,  that in no event shall the term of this  Agreement
         exceed the term that the License  Agreement  would have had it not been
         terminated  as described  above in this  Paragraph  5(b).
                   6.  Licensor agrees that Section M of the License  Agreement
         has been  satisfied in full by the issuance of four (4) shares of the
         common stock of Clearing Systems,  Inc.  ("CSI")  to Gerald  Singer and
         four (4)  shares of the common stock of CSI to

                                       3





         Arthur J. Murphy, and that Section M of the License Agreement is hereby
         terminated and of no further force or effect.
                  7.  Licensor  and  Network  agree that if any  improvement  or
         extension to the Inventions (as defined in the License Agreement) which
         improvement  or extension is  licensable to Network under Section A2 of
         the New License  Agreement is not  accepted by Network,  Jones shall be
         entitled  to  receive  immediately  from  Network  and/or  Licensor  an
         exclusive  license of such  improvement or extension to the same extent
         that  Network  would  have been  entitled  to receive it except for its
         failure to accept the license thereof.  In the event that Jones accepts
         such exclusive  license and pays the required  expenses with respect to
         the  improvement or extension in question as required under the License
         Agreement,  Jones shall be deemed to be granted a sublicense  under the
         New License  Agreement to the extent  necessary to enable him to use in
         commerce such improvement or extension.
                  8. As  compensation  for the  assignment all of Jones' rights,
         including but not limited to the license  under the License  Agreement,
         Network will pay to Jones Five Thousand  Dollars  ($5,000) per month on
         or before the 15th day of such month commencing with the month of June,
         1993 until operating kiosks are installed in a second store.
                  9. Upon  installation  of operating  kiosks in a second store,
         the payment to Jones will increase by One Thousand Dollars ($1,000) per
         month until it reaches the sum of Ten Thousand  Dollars  ($10,000)  per
         month.
                  10.  Following  collection  by Network  and/or its assignee or
         sublicensee  of
                                       4


gross  revenues  in an amount  sufficient  to trigger a
         reduction in the royalty percentage payable to Licensor under Section B
         of the License  Agreement,  the  compensation set forth in Paragraphs 8
         and 9 above will cease and Jones will then receive 1.7777% of the gross
         collected  revenues  of Network  and/or  its  assignee  or  sublicensee
         derived from the business of Network and/or its assignee or sublicensee
         as such business pertains to the Inventions (as that term is defined in
         the License  Agreement)  throughout  the  remainder  of the term of the
         License  Agreement,  or $10,000 per month,  whichever  is greater.  If,
         however, the License Agreement is terminated pursuant to Paragraph 5(b)
         hereof,  the  royalty  payment to Jones under this  Agreement  shall be
         $10,000 per month and no more.  Notwithstanding  the foregoing,  if the
         royalties  payable  under  the  License  Agreement  are  reduced  under
         Paragraph 1 of the Addendum,  the royalty  payable under this Agreement
         shall be (i) 1.7777% of the gross collected  revenues of Network and/or
         its assignee or sublicensee derived from the business of Network and/or
         its assignee or sublicensee as such business pertains to the Inventions
         other than those licensed by Stratton plus,  with respect to Inventions
         licensed  by  Stratton,  1.7777%  of the gross  collected  revenues  of
         Network and/or its assignee or sublicensee derived from the business of
         Network and/or its assignee or sublicensee as such business pertains to
         the Inventions  reduced by an amount  proportionate to the reduction in
         the royalty  payable to Licensor by Network  pursuant to Paragraph 1 of
         the  Addendum or (ii) $10,000 per month,  whichever is more.  With each
         payment  required  under this Paragraph 10, Network and/or its assignee
         or sublicensee will provide Jones a statement of its gross revenues and
         that of any assignee or sublicensee  and its computation of the payment
                                       5


         enclosed therewith (the  "Statement").  For purposes of this Agreement,
         the terms  "assignee"  and  "sublicensee"  are deemed to include one or
         more assignee or  sublicensee,  as the case may be, and any  subsequent
         assignee or sublicensee.

                  11. Network may grant  sublicenses and make assignments of its
         rights with respect to the license  assigned to it hereunder,  provided
         that any such  sublicense or  assignment  shall provide for payments to
         Licensor as required by the New License  Agreement  and for the payment
         to Jones of  royalties as set forth in  Paragraphs  8, 9 and 10 of this
         Agreement, if not paid by Network, and further provided that the rights
         granted  to  Jones  in  Paragraph  13  hereof  are  contained  in  such
         assignment or sublicense.

                  12. During the term of this Agreement, Jones will consult with
         and provide to Network whatever reasonable  assistance may be necessary
         and requested by Network in order to achieve the goals of Network.

                  13.  Jones  shall have the right at his own  expense,  and not
         more  often than once in each  calendar  quarter,  to have a  certified
         public accountant  examine the books of Network and/or its assignees or
         sublicensees to verify the Statements.  In the event that a discrepancy
         of more than 5% of the payments required under paragraph 10 is verified
         by Jones' accountant (which verification is not successfully  disproved
         by Network in a court of competent jurisdiction),  Network shall within
         60 days pay to Jones all  expenses of the  examination,  including  all
         reasonable  legal fees expended in sustaining any alleged  discrepancy,
         in addition to the additional royalties due.

                  14. In the event  that any  litigation  or claim is brought or
         made with  respect to the New License  Agreement  or any of the patents
         which are the subject matter thereof,
                                       6

                                       

         including, without limitation, a claim or defense of patent invalidity,
         the Licensor  shall  promptly give notice  thereof to Jones and Network
         and Jones and/or Network each, at his or its respective  option,  shall
         be entitled at his or its own cost and expense to be present at, and to
         participate  in,  conferences  with  persons  asserting  such  claim or
         lawsuit and any proceedings  with respect thereto and to be represented
         thereat by attorneys of his or its own choosing.

                  15. In the event that Jones  files a lawsuit  against  Network
         and/or its assignee or sublicensee to collect amounts allegedly owed by
         Network and/or its assignee or sublicensee to Jones hereunder and Jones
         is the  prevailing  party in said  lawsuit,  Jones shall be entitled to
         recover from Network and/or its assignee or sublicensee  all reasonable
         costs,  expenses and attorneys' fees incurred by him in connection with
         the lawsuit.  For the purpose of this Agreement,  "prevailing party" is
         defined  as the  party  in  favor of which  any  judgment  is  rendered
         regardless of the dollar amount of such judgment.

                  16.  This  Agreement  sets  forth  the  entire  agreement  and
         understanding  of the parties hereto with respect to the subject matter
         hereof  and  supersedes   all  prior   agreements,   arrangements   and
         understandings  related thereto.  This Agreement may not be modified or
         amended in any manner except by written agreement.

                  17. The covenants  and  agreements  contained  herein shall be
         binding  upon and inure to the  benefit of the  parties  hereto,  their
         heirs, executors, administrators, successors, legal representatives and
         assigns.  Without limiting the foregoing in any way, it is specifically
         agreed by all parties  hereto that Network may assign or

                                       7 


         sublicense  any or  all  of  its  rights  and  obligations  under  this
         Agreement  and  the  New  License  Agreement  to  Interactive  Networks
         Incorporated  or any other party.
                 18. Any notice required or permitted to be sent under the terms
         of this Agreement shall be deemed sufficient if  transmitted  by
         certified or  registered  mail,  or any  nationally recognized
         overnight delivery service,  addressed to the parties at the addresses
         first above written.
                19. This Agreement shall be interpreted under and pursuant to
         the laws of the State of North Carolina,  and the parties consent to
         jurisdiction in said state. IN WITNESS WHEREOF,  the parties hereto
         have  executed  this  Agreement  as of the date  first written above.

                                LICENSE AGREEMENT

         This  Agreement  is made as of the 31st day of  December,  1990 between
Michael  R.  Jones,  an  individual,  residing  at 233  Palmer  Hill  Road,  Old
Greenwich,  CT 06870 (hereinafter referred to as "Licensee"),  and Gerald Singer
an individual using an address of 3142 Pacific Coast Highway, Torrance, CA 90505
and  Arthur  J.  Murphy  an  individual   residing  at  18337  Superior  Street,
Northridge, CA 91324 (hereinafter collectively referred to as "Licensor").

         WHEREAS,  Licensor  represents  and warrants to Licensee  that Licensor
owns not less than fifty-five  (55%) percent of U.S. Patent Number 4,554,446 and
of  U.S.  Patent  Number  4,672,377  (henceforth  collectively  referred  to  as
"Inventions");

         WHEREAS,  Licensor represents and warrants to Licensee that Licensor is
legally  empowered to grant a non-exclusive  license in and to the  manufacture,
and/or sale and/or use of the Inventions in the United States and throughout the
world;

         WHEREAS,  Licensee  desires to obtain rights in and to the  manufacture
and/or sale and/or use of the Inventions in the United States and throughout the
world;

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

A.       License.

1. Licensor hereby grants to Licensee the non-exclusive right and license in the
United States and  throughout  the world to  manufacture,  use and sell, and the
right to grant non-exclusive sub- licenses for the manufacture,  use and sale of
the Inventions in the United States and  throughout  the world.  Notwithstanding
the foregoing the license  hereby granted shall be exclusive with respect to all
rights held by Licensor.

2. The term Inventions shall include any improvement or extension, patentable or
not, made by Licensor or Licensee or their representatives,  employees,  agents,
assignees or  contractors,  which  improvement or extension shall be assigned to
Licensor  and  immediately  upon such  assignment,  shall be made subject to the
terms of this  license,  provided  that  Licensee  subject to paragraph A5 shall
retain the right to decline to participate in said improvements or extensions.

3. Licensee agrees to obtain the necessary  agreements to assign any improvement
to the Inventions from its employees, agents, assignees or contractors.

4. The terms  "improvement"  or "extension" to the Inventions  shall include any
process or apparatus  involving  related equipment and other means heretofore or
hereafter utilized in the process involved in the original Inventions or related
process or extensions,  all test reports,  data and other information  developed
with reference to said process, and all improvements and refinements

                                      9





whether or not any application for a patent is filed.

5.  Licensee  shall pay all legal  costs and  expenses  incurred  in filing said
improvement patent and shall use patent attorneys selected by Licensor, provided
however that  Licensee  expressly  reserves the right to reject any  improvement
patent  application  submitted by Licensor and in so doing Licensee shall not be
obligated to pay any costs or expenses  incurred in obtaining  said  improvement
patent.  Licensor shall at all times be permitted to file and obtain improvement
patents at its own expense in the event that Licensee  declines to  participate.
Any  improvements or extensions not rejected by Licensee shall be subject to the
same terms and conditions of this license agreement.  In the event that Licensee
rejects any improvement patent  application and Licensor  prosecutes and obtains
such patent, Licensee shall be entitled to bring such patent under the terms and
conditions of this License  Agreement by reimbursing  Licensor for all costs and
expenses  incurred in obtaining such patent provided  further that Licensor then
retains such rights.

B.       Royalties.

1.  Licensee  shall pay to the  Licensor a royalty of four  percent  (4%) of the
gross  collected  revenues  derived from the business of Licensee,  only as such
business  pertains to the  Inventions,  until  Licensor  shall have received the
aggregate  sum of Five  Hundred  Thousand  ($500,000)  Dollars.  At such time as
Licensor has  received the  aggregate  sum of Five Hundred  Thousand  ($500,000)
dollars,  then the royalty  shall be reduced to two and two thousand two hundred
and twenty three ten thousands percent (2.2223%) of the gross collected revenues
derived from the business of the Licensee, only as such business pertains to the
Inventions.  Notwithstanding  the foregoing,  Licensee shall pay to Licensor not
less than the sum of Six  Thousand  ($6,000)  Dollars per month during the first
year of this  agreement  and not less than Ten  Thousand  ($10,000)  Dollars per
month during the balance of the term of this agreement.

2 . Licensee shall maintain accurate accounts of its operations coming under the
scope of this  license  agreement  and shall  submit to  Licensor  in  writing a
statement of  operations  within thirty (30) days after the end of each calendar
quarter.

3.  Licensee  shall  include  with the  quarterly  statement  the payment to the
Licensor in the
amount of the royalties accrued during the quarterly period.

4.  Licensor  shall have the right at its own  expense,  and not more often than
once in each quarterly period,  to have certified public accountant  examine the
books of the  Licensee  to verify the  royalty  statements.  In the event that a
discrepancy  of more than five (5%) percent of the collected  gross  revenues is
verified by Licensor's accountant, the Licensee shall within sixty (60) days pay
all expenses of the examination in addition to the additional royalties due.

C.       Term.

This  license is granted  for a period of thirty  (30) years or for such  longer
period as any patent for the  Inventions  including  improvements  or extensions
which have been accepted by Licensee under

                                       10





paragraph A5 hereof  shall be in force or in effect in the United  States or any
other country.

D.       Termination.

1. If the Licensee  defaults by failing to render statements or to make payments
of  royalties  as herein  provided,  the  Licensor  may give notice  pursuant to
section J of default by Licensee.  If such  default is not cured  within  thirty
(30)  days  from  the  date of  said  notice,  this  agreement  shall  terminate
automatically upon the date set forth in such notice without prejudice, however,
to all monies then due to the Licensor.

2. In the event Licensee  fails to exploit either of the two patents  comprising
the  Inventions  by failing for a period of one (1) year from the  execution  of
this agreement to manufacture and install a system based at least in part on one
of the patents in the United States or in any other country,  then in that event
Licensor  may on thirty (30) days  written  notice  immediately  terminate  this
agreement without prejudice, however, to all monies then due to the Licensor.

3. Either party, may terminate this license agreement at any time after only the
minimum payments called for in paragraph B1 shall have been paid to the Licensor
for any period of twelve (12) consecutive months.

4. This License  Agreement  shall  terminate  and all rights to said  Inventions

MEMO

                  Michael Jones

FROM:             Tim Hubbard
DATE:             6/10/93

We agreed as follows  and I am having  the  appropriate  documents  drawn up and
passed around for signatures.

1. The  license to  Michael  Jones is current  and valid and  unbreached  in all
respects.

2. Regarding the $5,000 threshold upon which the royalties due will be modified,
the patent  holders are credited with  $244,000 not including  this May and June
payments.

3. Paragraphs M, D2, and D3 of the License agreement  between  Murphy/Singer and
Jones have all been satisfied in full.

4. INI, NC is issuing  2,816,900  share of stock 816,900 (29%) will go to CSI as
payment for the purchase of all of its assets.

5. Murphy/Singer will each receive CSI founders stock in an amount equivalent to
22,911  shares of INI,  NC stock.  It is planned  that INI, NC stock held by CSI
will be  distributed  to CSI  shareholders  within the next few  months.  In any
event,  INI, NC agrees to convert  Murphy's  and  Singer's CSI stock into 22,911
shares of INI, NC stock  respectively,  if that conversion is not otherwise made
for all CSI shareholders as planned.  The plan is that all CSI shareholders will
be converted to INI, NC shareholders  within the next 6 months, but in any event
as soon as we can do so.

6. If the March,  1994  consulting  fee due from INI, NC to CSI, of which Jones'
portion is $216,000,  becomes due and payable prior to March, 1994, then at that
time, Murphy and Singer will be notified in writing and may request,  within one
week and in writing that Jones  purchase all or a portion of the stock  referred
to in  Para.  5  above.  If the  request  is  made,  then  INI,  NC will pay the
appropriate  amount of Jones'  portion of the  consulting  fee to Murphy  and/or
Singer on behalf of Jones.  The appropriate  amount will be determined  based on
the ratio of $5.32 per share of INI, NC stock of its equivalent if CSI stock.

7. Jones agrees that, if by November 1, 1993, the March, 1994 consulting fee due
CSI has not  become  due and  payable,  Murphy  and/or  Singer  may  request  in
November,  1993 that Jones buy up to 50% of their respective  shares referred to
in Para.  5 above,  Jones agrees that he will  purchase  shares from each at the
rate $5.32 per share of INI, NC stock or its equivalent if CSI

                                       18




stock within 30 days of the request.  If Jones fails to purchase these shares in
a timely  fashion,  then INI, NC agrees that it will do so within 14  additional
days.

8. Jones agrees that, if by March 1, the March,  1994 consulting fee due CSI has
not become  due and  payable,  Murphy  and/or  Singer may  request in writing in
March,  1994 that Jones buy up 50% of their  respective  shares  referred  to in
Para. 5 above,  Jones agrees that he will  purchase  these at an amount based on
the  ratio of $5.32 per share of INI,  NC stock or its  equivalent  if CSI stock
with 30 days of the request. If Jones fails to purchase these shares in a timely
fashion, then INI, NC agrees that it will do so within 14 additional days.

Please indicate your agreement with the above by signing below. Fax a copy to me

If both  Jones  and INI,  NC fail to  purchase  shares in  accordance  with this
agreement, Tim Hubbard agrees to purchase rights 50% of the number they would be
