                  interest in all of the accounts  receivable  and  inventory of
                  ITC Canada and the NSBDC Security shall be enforced subject to
                  the  rights  of  Wachovia  to  the  accounts   receivable  and

                  payment of any other  obligation  of ITC Canada to  Wachovia

                  3.1(b).

      3.2   Any  proceeds  received  by ITC Canada or by NSBDC or by Wachovia in
            respect of assets of ITC Canada charged by the NSBDC Security or the

            provisions  hereof as so paid or payable as proceeds of  realization
            of the  collateral  for  which  they  compensate,  and all  proceeds
            received by ITC Canada  shall be held in trust by it for the benefit
            of NSBDC and  Wachovia  as the case may be, in  accordance  with the
            provisions hereof.

      3.3   The  provisions  hereof shall apply in all events and  circumstances
            regardless of:

                                       3


            (a)   the date of execution, attachment, registration, perfection or
                  reperfection  of  any  security  interest  held  by  NSBDC  or
                  Wachovia;

            (b)   the date of any  advance  or  advances  made to ITC  Canada by
                  NSBDC or to ITC Learning Corporation by Wachovia;

            (c)   the date of  default  by ITC  Canada  under  either  the NSBDC
                  Security or the Wachovia Security, the date of crystallization
                  of any  floating  charges  held by NSBDC or by Wachovia or the
                  date of any enforcement action of either of them;

            (d) any priority granted by any principle of law or any statute.

      3.4   If any of the NSBDC Security or the Wachovia Security is found to be
            unenforceable,  invalid,  unregistered  or  unperfected  against any
            party  other  than  NSBDC  or  Wachovia  by  a  court  of  competent
            jurisdiction,  and all  appeals  from any such party have been heard
            and  determined  or the time for making any such  appeal has expired
            without an appeal being made,  the  provisions of Section 3.1 to and
            including 3.3 of this Agreement  shall not apply to such security to
            the extent that it is so found.

4.    DEFAULT AND DEMAND

      4.1   In the event that there is a default by ITC Canada  with  respect to
            the  NSBDC  Debt or the  Wachovia  Debt  which  results  in NSBDC or
            Wachovia  notifying  ITC Canada in  writing of such a default,  then
            NSBDC or  Wachovia,  as the case may be,  shall  give a copy of that
            written notice of default to the other coincidentally with it giving
            such notice to ITC Canada.

      4.2   Either  party may, in  accordance  with the terms of its  respective
            loans,  demand  repayment  from ITC  Canada.  Not less  than two (2)
            business  days before  issuing a demand,  NSBDC or Wachovia,  as the
            case may be, shall give notice to the other providing particulars of
            the default  and a copy of the  intended  demand.  In the event that
            either NSBDC or Wachovia  believes  that the two (2)  business  days
            notice as hereinbefore  provided may adversely affect its ability to
            enforce its security and to recover its indebtedness, it may proceed
            without  giving  such  two (2)  business  days  notice  but it shall
            nevertheless  provide  to the  other  any  notice of demand or other
            proceedings which it may serve upon ITC Canada.

      4.3   In the event that NSBDC or  Wachovia  gives  notice as  provided  in
            article  4.2  hereof,  then NSBDC or  Wachovia,  as the case may be,
            within two (2) business  days from the date of receipt of the notice
            shall have the right to pay to the other the  amount of the  other's
            debt then  outstanding and to take an assignment of the other's debt
            and an  assignment  of the  other's  interest  in  either  the NSBDC
            Security or the Wachovia Security.

                                       4



5.    RECOVERY

      5.1   In the event that  either  NSBDC or  Wachovia  desires to appoint an
            agent or receiver to invoke any other process to effect  recovery of
            its  indebtedness  or to realize upon its  security,  it shall first
            attempt to consult with the other and to agree as to the appointment
            of a common  agent or receiver  and as to the process to be followed
            with respect to recovery.  However, neither NSBDC nor Wachovia shall
            be barred from  appointing  an agent or receiver or to effect  other
            process,  by  failure to  contact  the other,  or to agree as to the
            terms of the appointment, provided always that any agent or receiver
            appointed will be a licensed  trustee in bankruptcy  employed with a
            national accounting firm.

      5.2   If the parties agree to a common course of action in accordance with
            article 5.1 and any matter  arises which  requires a direction to be
            given to the agent or the  receiver or approval of any step taken or
            any act to be done in and  about  the  management  of the  agency or
            receivership,  then the matter shall be decided jointly by NSBDC and
            Wachovia. If NSBDC and Wachovia are unable to agree on the direction
            to be given then another licensed trustee,  independent of the agent
            or receiver,  and selected by the agent or the receiver shall decide
            on the direction to be given.

6.    DISTRIBUTION OF PROCEEDS

      6.1   Any monies and  proceeds  received by NSBDC or Wachovia  pursuant to
            any  realization on or enforcement of the NSBDC Security or Wachovia
            Security,  as the case may be, whether from sale, insurance proceeds
            or other  source of funds,  or under  any  dissolution,  winding-up,
            liquidation  or  other  scheme  of  arrangement  or any  insolvency,

            (c)   thirdly,  in payment of the  Wachovia  Debt to the extent that
                  such  monies and  proceeds  derive  from the  inventories  and
                  accounts  receivable  of ITC  Canada and there is at such time
                  outstanding Wachovia Debt owed to Wachovia;

            (d)   fourthly,  distributed  pari passu in payment of the  Wachovia

                                       5


            (e)   fifthly,  in the  event  that  after  the  application  of the
                  recoveries pursuant to the preceding  paragraphs hereof, there
                  is still  additional  monies  and at that time  there is still
                  outstanding Wachovia Debt, the amount of such surplus shall be
                  paid to the Wachovia to be applied against the Wachovia Debt;

            (f)   sixthly,  in the event that after repayment of the amount owed
                  to NSBDC on the Cdn. $2,000,000 note there is still NSBDC Debt
                  outstanding, the amount of any surplus monies shall be paid to
                  NSBDC to be applied to the NSBDC Debt;

            (g)   seventhly,  as to any surplus,  after  repayment of NSBDC Debt
                  and Wachovia Debt as hereinbefore  provided for, to such other
                  persons or  corporations as required by the terms of the NSBDC
                  Security and Wachovia Security or as required by law.

      6.2   Should NSBDC or Wachovia receive any payments, distributions,  funds
            or  proceeds  contemplated  under  this  article  6,  then they must
            provide an  accounting  to the other in  connection  therewith  upon
            request.

      7.1   From time to time upon  request  therefore,  NSBDC and  Wachovia may
            advise  each  other  of  the  particulars  of the  indebtedness  and
