Item 2.  Acquisition or Disposition of Assets.

       On September 25, 1998, ITC Canada Limited ("ITC Canada"),  a wholly owned
and newly  formed  subsidiary  of ITC  Learning  Corporation  ("ITC  Learning"),
acquired  substantially  all of the assets and the  business of Mentor  Networks
Inc. and its wholly owned  subsidiary,  High  Performance  Group  (collectively,
"Mentor"), of Halifax, Nova Scotia, Canada. Mentor has engaged since 1993 in the
development and distribution of multi-media  interactive courseware products for
the corporate educational market.

       ITC  Learning  invested  U.S.  $1 million in Mentor in January of 1998 in
exchange for 8% of Mentor's  outstanding  common stock and the option to acquire
an additional  12% through the exercise of warrants.  At that time, ITC Learning
and Mentor  also  entered  into a reseller  agreement  awarding  ITC  Learning a
one-year  exclusive right to distribute  Mentor PC Skills Products in the United
States.  In June,  ITC  Learning  and Mentor  amended  the  reseller  agreement,
extending it to three years. ITC Learning also agreed to prepay U.S. $300,000 to
Mentor under the reseller agreement and gave up its option to acquire additional
Mentor  common  stock,  in exchange  for an improved  pricing  scheme  under the
reseller agreement.

       On July 20,  1998,  Mentor was placed  into  receivership  by its secured
lender, the Nova Scotia Business Development Corporation ("NSBDC"). Based on ITC
Learning's familiarity with Mentor's products, the existing relationship between
ITC  Learning  and  Mentor  under  the  reseller   agreement,   the  substantial
integration  of Mentor's  products into ITC Learning's  library,  ITC Learning's
desire to assure  continued  and  expanded  access  to Mentor  products  and ITC
Learning's  due  diligence  investigation  subsequent to the  receivership,  ITC
Learning submitted a bid to purchase the assets and business of Mentor.

       Under the  agreement  reached with the NSBDC,  ITC Canada  purchased  the
assets and  business of Mentor for Cdn. $1 million of cash  (approximately  U.S.
$661,000) and a five-year promissory note at 8% interest payable to the NSBDC in
the amount of Cdn. $2 million (approximately U.S. $1,320,000), plus an agreement
to pay up to Cdn. $1.6 million (approximately U.S. $1,058,000) in certain future
royalty payments based on the ongoing  performance of the Mentor assets. As part
of the  transaction,  ITC  Learning  also  committed  to provide ITC Canada with
working capital up to Cdn. $1.1 million  (approximately US $727,000).  (The U.S.
equivalent  for all amounts shown as payable are at current  exchange  rates and
the  actual  amount  paid  in  U.S.  dollars  may be  different  depending  upon
fluctuations in exchange rates.)

       The Mentor  assets will be  combined  with ITC  Learning's  Toronto-based
sales and marketing office and will be operated by ITC Canada. The source of the
funds  required to  consummate  the Mentor  acquisition  were  derived  from ITC
Learning's working capital and its line of credit with Wachovia Bank, N.A.

                                       2

       As a result of the acquisition,  ITC Canada acquired 42 employees,  34 of
whom are technical  development  personnel.  ITC Canada also  acquired  seven PC
Skills titles associated with the Microsoft Office Suite(TM) of products,  three
call center titles, intellectual property rights to an additional 25 soft skills
products and certain fixed assets. Following the acquisition,  ITC Learning will
continue to use these assets to develop and distribute multimedia courseware for
corporate North America.

       A copy of ITC  Learning's  press release issued on September 29, 1998, is
attached and incorporated herein.

Dear Sirs:

      Re:   Mentor Networks Inc.
            - Assignment of Lease by Receiver to ITC Canada Limited

      As you are  aware,  we have  been  acting  as  solicitors  to Nova  Scotia
Business Development Corporation and to Grant Thornton Limited,  receiver of the
property  and  assets of Mentor  Networks  Inc.  and of High  Performance  Group
(Canada) Inc.

      I refer to the terms of the lease entered into by you with Mentor Networks
Inc., a copy of which attached, and the terms of the Indenture agreement between
Purdy's Wharf Development Limited, Nova Scotia Business Development Corporation,
and Mentor  Networks Inc. and High  Performance  Group (Canada) Inc. dated April
29, 1997, a copy of which is attached.

      Grant  Thornton  Limited as receiver  appointed  by Nova  Scotia  Business
Development Corporation has agreed to assign the lease to ITC Canada Limited and
you have indicated that the landlord is prepared to consent to this  assignment,
provided the assignee, ITC Canada Limited,  agrees to be bound by all covenants,
terms and conditions of the attached lease.

      It would be  appreciated  if you would  confirm  your consent by signing a
copy of this  letter and  returning  it to me. I will treat your  signing of the
letter as confirmation of the approval and also confirmation of your advice that
there is no  default  under the lease and that there is no  outstanding  rental,
save for the amount of  $36,700.41  payable on September  18, 1998 in accordance
with your invoice number 980920, dated August 28, 1998, and outstanding invoices
#98065 dated July 6, 1998 for lights and #9806EX  dated July 13, 1998 for excess

Landlord but chargeable to Tenant under this lease.

5.3   Real Estate Taxes

      5.3.1 Definitions

      For the purposes of this Article:

      (1)   "Real Estate Taxes" means all taxes, rates and assessments,  general
            and  special,  levied  or  imposed  with  respect  to  the  Building
            (including any accessories and improvements  therein or thereto) and
            the Land and all improvements  thereto  including where  applicable,

            levied or imposed for schools,  public betterment,  general or local
            improvements.

            If the  system of real  estate  taxation  shall be altered or varied
            and/or  any  new tax or levy  shall  be  levied  or  imposed  on the
            Building  and/or  the Land  and/or  the  revenues  therefrom  and/or
            Landlord in substitution for and/or in addition to Real Estate Taxes


                                       5
<PAGE>

            presently  levied or  imposed  on  immovables  in the city,  town or
            municipality  in which the Building  and Land are situate,  then any
            such new tax or levy shall be included  within the term "Real Estate
            Taxes" and the  provisions  of this Article 5.3 shall apply  MUTATIS
            MUTANDIS.

            The amount of the Real  Estate  Taxes  which shall be deemed to have
            been levied or imposed  with  respect to the  Building  and the Land
            shall be such  amount as the legal  authority  imposing  Real Estate
            Taxes  shall  have   attributed   to  the   Building  and  the  Land
            respectively,  or, in the absence of such  attribution,  or, if such
            legal  authority  shall  include  other  immovables  other  than the
            Building  and the Land in  imposing  such Real  Estate  Taxes,  such
            amount as Landlord  in the  exercise of  reasonable  judgment  shall
            establish.

      (2)   If in any year,  the taxing  authority  has not fully  assessed  and
            fully taxed the Building and Land as entirely completed and entirely
            occupied by tenants  having no special  exemptions  with  respect to
            Real Estate  Taxes,  then taxes shall be adjusted and  determined by
            including  therein such additional  amount as would have formed part
            of Real  Estate  Taxes if the  Building  and  Land  had  been  fully
            assessed and fully taxed as entirely completed and entirely occupied
            by tenants having no special exemptions.

      (3)   Real  Estate  Taxes shall be  determined  without  reference  to, or
            deduction  for,  any  abatement,  concession  or  reduction of taxes
            provided or granted as an  incentive to builders or  developers  and
            Real Estate  Taxes shall be adjusted  and  determined  by  including
            therein the amount of any such concession, abatement or reduction.

      5.3.2 Real Estate Taxes Payable

            The rent  payable  during  the term of this lease in respect of each
      year  shall be  increased  by an amount  equal to the  Proportion  of Real
      Estate Taxes attributable to such year. Tenant shall pay to Landlord,  not
      later than 10 days prior to the tax due date, or such other date as may be
      specified in writing to Tenant by Landlord (hereinafter referred to as the
      "Specified Date"), the amount of such increase in the annual rent.

            At the option of Landlord, Landlord may at any time and from time to
      time  estimate  the amount of  increased  rent as will  become  payable by
      Tenant by the tax due date or Specified  Date,  and bill Tenant  therefor,
      and in such event  Tenant  shall pay to  Landlord  the full amount of such
      estimate in equal  monthly  installments  commencing  with the first month
      following  such estimate and  terminating on the tax due date or Specified
      Date.  Such  monthly  amounts  when paid to  Landlord  shall be  available
      (without  interest) as a credit against  Tenant's  obligations to Landlord
      under this Article 5.3.

            Any amounts  payable by Tenant  hereunder shall be adjusted on a pro
      rata basis to reflect the actual  commencement  and  termination  dates of
      this lease having regard to the period in respect of which the calculation
      of Real Estate Taxes is made.



                                       6
<PAGE>

            The  obligations  of the parties  hereto to adjust  pursuant to this
      Article  5.3.2  for the  final  period  of the  lease  shall  survive  the
      expiration of the term of this lease.

            Landlord shall furnish to Tenant upon the specific  written  request
      of Tenant copies of all pertinent  valuation and assessment notices and of
      all pertinent tax bills and notices received by Landlord.

      5.3.3 Expenses for Contestation

            Tenant shall pay to Landlord as  additional  rent the  Proportion of
      any expenses,  including  legal,  appraisal,  administration  and overhead
      expenses,  incurred by Landlord in  obtaining  or  attempting  to obtain a
      reduction of any Real Estate Taxes.  Real Estate Taxes which are contested
      by Landlord shall nevertheless be included for purposes of the computation
      of the liability of Tenant under Article 5.3.2 provided,  however, that in
      the event  that  Tenant  shall  have paid any  amount  of  increased  rent
      pursuant  to this  Article 5.3 and  Landlord  shall  thereafter  receive a
      refund of any portion of the Real Estate Taxes on which such payment shall
      have been based,  Landlord shall pay to Tenant the appropriate  portion of
      such refund after deduction of the aforementioned expenses.

            Landlord  shall  have no  obligation  to  contest,  object  to or to
      litigate  the  levying  or  imposition  of any Real  Estate  Taxes and may
      settle,  compromise,  consent  to,  waive or  otherwise  determine  in its
      discretion any Real Estate Taxes without notice to, consent or approval of
      Tenant.

      5.3.4 No Reduction in Rent

            Nothing contained in this Article 5.3 shall be construed at any time
      so as to reduce the monthly  installments of rent payable  hereunder below
      the amount stipulated in Article 5.1.

5.4   Operating Expenses

      5.4.1 Definitions

            For the purposes of this  Article,  "Operating  Expenses"  means the

option,  give to Tenant a written  notice of its  intention  to  terminate  this

notice or legal process whatsoever,  provided always, however, that Tenant shall
remain  liable  to pay all  amounts  and  damages  then  due or to  become  due,

unexpired portion of the term.

29.4  The exercise of any Right of Landlord

      Failure of  Landlord  to insist upon the  performance  of any  covenant or
condition  of this lease or to exercise  any right or option  contained  in this
lease shall not be construed as a waiver or relinquishment of any such covenant,
condition,  right or option.  No  violation of any covenant or condition of this
lease shall be valid unless in writing and signed by duly authorized  persons on
behalf  of  Landlord.  The  acceptance  of rent from or the  performance  of any

furniture  or other  property on the  Premises and to sell the same at public or
private sale without  notice and to apply the proceeds of such sale and any rent
derived form  reletting  the Premises  upon account of the rent under this lease
and Tenant shall be liable to Landlord for the deficiency, if any.

29.7  No Limitation on Right to Distrain

      Tenant waives and  renounces the benefit of any present or future  statute
taking away or limiting  Landlord's  right to distress and  covenants and agrees
that  notwithstanding  any such statute none of the goods and chattels of Tenant
on the  Premises  at any time  during  the term  shall be  exempt  from  levy by
distress for rent or any other charges; all goods and chattels brought by Tenant
onto the Premises  shall be the  unencumbered  property of Tenant and they shall

written consent of Landlord. If Tenant shall leave the Premises leaving any rent
or other  amounts owing under this lease  unpaid,  Landlord,  in addition to any
other available  remedy,  may seize and sell the goods and chattels of Tenant at
any place to which  Tenant or other  person may have  removed  them in t he same
manner as if such goods and chattels have remained and been  distrained upon the
Premises. Notwithstanding the provision of this paragraph 29.1 (7) and paragraph
23.1,  Tenant  shall have the right to grant the  charges on its  furniture  and
equipment which have priority over the Landlord's  right to distrain as security
for financing to lenders who are at arms' length with the Tenant.

                                  SCHEDULE "C"

      The  method of  measuring  office  building  rentable  area  shall be that
      developed by the Building  Owners and Managers  Association  International
      and published in their booklet  "Standard  Method for Measuring Floor area
      in Office Building" reprinted May 1981.

      Rentable  area is a measure of the tenants pro rata  portion of the entire
      office floor,  excluding elements of the building that penetrate the floor
      to area below.  The rentable  area of a floor is fixed for the life of the
      building   and  is  not   affected  by  changes  in   corridor   sizes  or
      configurations.

      The  rentable  area of a floor is  computed  by  measuring  to the  inside
      finished  surface of the dominant  portion of the permanent outer building
      walls  excluding any major  penetrations  of the floor.  No deductions are
      made of  columns  and  projections  necessary  to the  building.  Dominant
      portion means that portion of the inside finished surface of the permanent
      outer building wall which is 50% or more of the vertical  floor-to-ceiling
      dimension measured at the dominant portion. If the dominant portion is not
      vertical, the measurement for area shall be to the inside finished surface
      of the permanent  outer  building  wall where it  intersects  the finished
      floor. In the subject  building the dominant portion is the inside surface
      of the exterior windows.

      PROPORTION FORMULA

                              A     =     net rentable area of tenant

                              B     =     net rentable area of
                                          Tower 1 and Xerox Building

         (d)      it  will  after  the  security   hereby   created  has  become
                  enforceable  and NSBDC has determined to enforce it, from time
                  to time,  execute  and do all such  assurances  and  things as
                  NSBDC may reasonably  require for facilitating the realization
                  of the Mortgaged  Premises and for  exercising all the powers,
                  authorities  and discretions  hereby  conferred upon NSBDC and
                  for  confirming  to any  purchaser  of  any  of the  Mortgaged

                  judicial  proceedings,  the title to the property so sold, and
                  that it will  give all  notices  and  directions  as NSBDC may
                  consider expedient;

         (e)      at any and all times the Company will do, execute, acknowledge
                  and deliver or will cause to be done,  executed,  acknowledged
                  and  delivered  all  and  every  such  further  acts,   deeds,

                  transfers  and  assurances  in law as NSBDC  shall  reasonably
                  require,  for the  purpose of giving NSBDC a valid assignment,
                  transfer,  mortgage,  hypothecate,  charge or  security of the
                  nature herein  specified upon all property,  whether now owned

9.       Until the security  hereby  constituted  becomes  enforceable and NSBDC
         determines  to enforce it, the Company  shall be  permitted in the same
         manner  and to the  same  extent  as if this  Debenture  had  not  been
         executed,  but  subject  to the  express  terms  thereof,  to  possess,
         operate,  manage,  use and  enjoy  the  Mortgaged  Premises,  freely to
         control  the  conduct  of its  business  and to take and use the rents,

                  discharging any such  indebtedness so long as it in good faith
                  contests  liability  therefor,  and provided  further that the
                  Company may upon delivery to NSBDC of a certificate  signed by

                        supplied with up to date copies of all policies therefor
                        and  to be  paid  the  proceeds  of any  claims  payable

                        property  of  the  Company  of a  character  so  usually
                        insured, and shall furnish NSBDC with particulars of all
                        insurance  covering the  Mortgaged  Premises or any part

                  connection   with   the   transactions   therein   or   herein
                  contemplated  (either  as  therein  stipulated  or as they may
                  hereafter  from time to time be  amended)  including,  without
                  limitation,  the reasonable  charges and  disbursements of its
                  financial consultant retained at the request of the Company or
                  retained in the event NSBDC deems its security in jeopardy and
                  its  counsel  and any  counsel  whom it or they may consult on
                  matters  of the laws of any  jurisdiction  which  its  counsel
                  deems relevant to the transaction  therein  contemplated,  for
                  the   services  of  such  counsel  in   connection   with  the

                  or in respect thereof and any monies so paid or costs, charges
                  or  expenses  incurred  by NSBDC in respect  thereto  shall be
                  added to the principal monies secured by this Debenture and if
                  not paid by the  Company  within 30 days of demand  shall bear

                  consent of NSBDC  delay  payment of such taxes or  assessments
                  for such period as NSBDC may agree and further  provided  that
                  if the Company  bona fide  disputes  the legality or amount of

                  Mortgaged  Premises  in  priority  to  the  security  of  this
                  Debenture  remains unpaid after proceedings have been taken to
                  enforce it as such  prior  charge or for a period of more than
                  five (5) days after NSBDC has demanded  that such sum be paid;
                  or

         (e)      if the  Company  becomes  bankrupt  within the  meaning of the
                  applicable  bankruptcy  law or  insolvent  or makes a  general

                  create  any  mortgage,  pledge,  charge,  assignment  or other
                  security,  whether fixed or floating on the Mortgaged Premises
                  or  any  part  thereof  other  than   encumbrances   expressly
                  authorized by any provisions hereof; or

         (h)      if the  Company  neglects  to carry out or  observe  any other
                  covenant or condition of this Debenture; or

         (i)      if the Company or any of its  affiliates  falls to perform any
                  of their obligations undertaken in favour of NSBDC pursuant to

                  or any other agreements  between the Company or its affiliates
                  and NSBDC; or

         (j)      if the Company shall make default under the  provisions of any
                  instrument creating a charge on the Mortgaged Premises ranking
                  after the security of this  Debenture  unless within such time
                  as will  prevent the  exercise  under such  instrument  of the
                  remedies provided therein or available  thereunder in cases of
                  default and in any event within 30 days from receipt of notice
                  to that effect from NSBDC,  the Company  remedies such default
                  and the rights of NSBDC hereunder have not been  prejudicially
                  affected;   or  if  the  trustee  or  holder  under  any  such
                  instrument,  whether or not any such  default  shall have been
                  made shall take any  proceedings  with a view, to appointing a
                  receiver or with a view to entering upon or foreclosing on the
                  Mortgaged Premises.

12.      Any time  after an event of default  has  occurred  NSBDC may,  on such
         terms and conditions (if any) as it may prescribed,  waive such default
         and/or  that  part of  Section  I 1  hereof  rendering  this  Debenture
         outstanding  immediately due and payable,  provided that no such waiver
         shall affect or be deemed to affect in any way any  subsequent  default
         or any rights resulting therefrom.

13.      Whenever the security hereby  constituted shall have become enforceable
         NSBDC may:

         (a)      by  instrument  in  writing  appoint  any  person or  persons,
                  whether an  employee  or  employees  of NSBDC or not,  to be a
                  receiver ("receiver" in this Section 13 includes receivers;  a
                  receiver  and  manager;  and  receivers  and  managers) of the
                  Mortgaged Premises or any part thereof,  wherever located, and
                  may remove any  receiver so appointed  and appoint  another in
                  his stead. Any such receiver so far as concerns responsibility
                  for his acts,  be the agent of the Company and NSBDC shall not
                  in any way be responsible  for any misconduct or negligence on
                  the part of such  receiver.  Any such receiver shall have such
                  powers as are set out in Section 13 (b) and (d) hereof,  shall
                  have power with or without  taking  possession to lease all or
                  any part of the  Mortgaged  Premises  to such  person and upon
                  such  terms as he deems fit and  shall  have the power to take
                  possession  of the  Mortgaged  Premises  or any  part  of such
                  property and to convey,  transfer and assign to a purchaser or
                  purchasers the title to any of the  undertaking,  property and
                  assets so sold.  Subject  to  NSBDC's  right of  waiver  under
                  Section 12 hereof the floating  charge  hereby  created  shall
                  crystallize on the earlier of:

                  (i)   the  commencement  of any  proceedings  in any  Court by
                        NSBDC to enforce the security herein constituted;

                  (ii)  the appointment  hereunder or by a Court of any receiver
                        of the Mortgaged Premises or any part thereof;

                  (iii) the  happening  of  any  event  sufficient  at law or in
                        equity to crystallize the said floating charge; and/or

         (b)      by its agents or attorney  take  possession of all or any part
                  or parts of the Mortgaged  Premises with full power to exclude
                  the  Company,  its agents and  servants  therefrom,  carry on,

                  thereof  under a judgment or decree of the court of  competent
                  jurisdiction  or by an  enforcement  of any other legal remedy

         (f)      NSBDC  may  foreclose  the  security  constituted  under  this

14.      On any sale or sales under  Section 13 hereof or  otherwise,  NSBDC may
         purchase  the  whole  or part of the  property  so sold  and may  apply
         towards the purchase price thereof this Debenture at an amount equal to
         the sum that would be  received in respect of this  Debenture  upon the
         distribution of the proceeds of such sale.

15.      After any default NSBDC may either  before,  during,  or after any act,
         action or  proceeding  for  realizing  upon the  Mortgaged  Premises or

         Company  hereunder  recover  judgment  against  the  Company  and  levy
         execution  thereon  for the whole  amount  then due and  payable to the
         Company.  The right to recover such  judgment  and levy such  execution
         shall  not be  affected  by any  entry  or  taking  possession  or sale
         hereunder or by the  exercise of any other  right,  power or remedy and
         the exercise of such right to recover judgment and levy execution shall
         not in any  mariner or to any extent  affect the Lien hereof or rights,
         powers, or remedies of NSBDC.

16.      No remedy  conferred  on NSBDC shall be deemed  exclusive  of any other
         remedy.  Each such remedy shall be cumulative  and in addition to every
         other remedy given hereunder or now or hereafter  existing at law or in
         equity and may be exercised from time to time and as often as is deemed
         expedient.

17.      Any and all moneys arising from any sale or realization of the whole or
         any part of the Mortgaged  Premises  shall be held by NSBDC,  IN TRUST,
         for the following purposes,  in the order of priority in which they are
         listed:

         (a)      to pay or retain the compensation,  cost, expenses and outlays
                  including any interest thereon incurred or payable by or to it
                  or any receiver as defined in Section 14 hereof in  connection
                  with such sale or realization;


                                       9
<PAGE>

         (b)      to pay or retain the costs of NSBDC taxed as between solicitor
                  and client of any  proceeding  in any Court  taken by NSBDC to
                  enforce the security herein constituted;

         (c)      to pay all  taxes,  assessments  and  other  charges  upon the
                  Mortgage  Premises to the extent  they form a charge  prior to
                  this Debenture;

         (d)      to pay or retain all  amounts  due and payable to NSBDC by the
                  Company for any reason  whatsoever,  under or pursuant to this
                  Debenture or otherwise;

         (e)      to pay the balance of such  moneys,  if any, to the Company or
                  to the Accountant General of the Supreme Court of Nova Scotia,
                  at the option to NSBDC.

18.      All amounts  described in Sections 17 (a), (b) and (c) hereof which are
         paid by NSBDC or any receiver  shall be added to the  Principal  Amount
         hereby  secured and shall be a charge upon the  property  and assets of
         the Company charged hereunder in priority to the Principal Amount.

19.      Upon  default by the Company and demand for  possession  by NSBDC,  the
         Company, its officers,  agents and servants shall immediately surrender
         and deliver to NSBDC all the  Mortgaged  Premises  and execute all such
         instruments  and do all such  acts and  things as may be  necessary  or
         desirable to put NSBDC in actual possession of the Mortgaged Premises.

20.      Any  notice  or  demand  upon  the  Company  shall be valid if given by
         postage prepaid  registered letter addressed to the principal office of
         the  Company  and shall be deemed  to have  been  served or given  five
         business days after the day such letter is posted. Nothing herein shall
         preclude  the  delivery  of  notices  or  demands  by means  other than
         mailing.

21.      No delay or omission of NSBDC to exercise  any right or power  accruing
         upon any  default,  shall  impair  any such  right or power or shall be
         construed to be a waiver of any such default or in acquiescence therein
         and every power and remedy  given  hereby to NSBDC may be  exercised by
         it, from time to time and as often as may be deemed by it.

22.      This security is in addition to and not in  substitution  for any other
         security now or hereafter held by NSBDC.

23.      This Debenture may be assigned, deposited and pledged by the Company as
         collateral  security for all of its present and future indebtedness and
         liabilities  to NSBDC  and,  when  redelivered  to the  Company  or its
         nominee,  shall be forthwith  cancelled,  provided  however,  that this
         Debenture  shall not be deemed to have been  redeemed  by reason of the
         account  of  the  Company  having  ceased  to be in  debit  while  this
         Debenture  was so assigned,  deposited or pledged and no payment  shall
         reduce  the  amount  owing  or  payable  under  this  Debenture  unless
         specifically  appropriated  to the payment on account of this Debenture
         at the time of payment.

24.      This Debenture and all of its provisions shall ensure to the benefit of
         NSBDC  and  shall be  binding  upon the  Company,  its  successors  and
         assigns.

      INTEREST RATE                          8% PER ANNUM

      FOR  VALUABLE  CONSIDERATION,  the  receipt  and  sufficiency  whereof  is
acknowledged  by  the  undersigned,   ITC  CANADA  LIMITED,  a  body  corporate,
incorporated  under the laws of Nova Scotia (the "Company"),  hereby assigns to,
deposits  with and  pledges  to NOVA  SCOTIA  BUSINESS  DEVELOPMENT  CORPORATION
("NSBDC") the debenture created by the Company and described above together with
all renewals thereof,  amendments thereto or substitutions  therefore,  interest
thereon and proceeds  thereof (the  "Debenture')  to be held by NSBDC as general
and  continuing  collateral  security  for the payment of all present and future
indebtedness and liability of the Company to NSBDC (the "Indebtedness").

      In the event of any  default by the  Company in payment of any part of the
Indebtedness  or in the  performance  of any other  obligation of the Company to
NSBDC,  NSBDC may at any time during the continuance of any such default realize
upon the  Debenture by sale,  transfer or delivery,  or exercise and enforce all
rights and remedies of a holder of the Debenture as if NSBDC were absolute owner
thereof, without notice to or control by the Company, and any such remedy may be
exercised  separately or in  combination  and shall be in addition to and not in
substitution for any other rights of NSBDC however created,  provided that NSBDC
shall not be bound to exercise any such right or remedy.

      The proceeds of the  Debenture  may be applied by NSBDC on account of such

the Company for any deficiency.

      NSBDC may grant extensions of time or other indulgences,  take and give up
securities,  accept  compositions,  grant  releases and discharges and otherwise
deal with the Company and with other  parties,  sureties or  securities as NSBDC
may see fit without  prejudice to the liability of the Company or NSBDC's rights
in respect of the Debenture.

      PROVIDED HOWEVER as follows:

      (a)   notwithstanding  that the  Debenture is in the  principal  amount of
            Cdn.  $3,600,000 the liability of the Company under the Debenture at
            any time shall be limited to the amount of the Indebtedness;

      (b)   notwithstanding  that the  Debenture  is  expressed to be payable on
            demand, payment may only be demanded upon the occurrence of an event
            of default under any instrument representing the Indebtedness or the
            Debenture;
<PAGE>

      (c)   payment  to NSBDC of  interest  for any  period  in  respect  of the
            Indebtedness,  whether before or after default,  in accordance  with
            the  terms  of  the   Indebtedness   shall  be  deemed   payment  in
            satisfaction  of the interest  payment for the same period under the
            Debenture.

      The  Debenture  shall  not  operate  by  way  of  merger  of  any  of  the
Indebtedness  and no judgment  recovered by NSBDC shall operate by way of merger
of or in any way affect the  security of the  Debenture  which is in addition to
and not in substitution for any other security now or hereafter held by NSBDC.

      This Debenture  Pledge  Agreement  shall be interpreted in accordance with
and governed by the laws of the Province of Nova Scotia and, for such  purposes,
the Company  hereby  irrevocably  consents  and  submits,  both as to person and
subject  matter,  to the  jurisdiction  of the courts of Nova  Scotia and to the
entry of any judgment rendered in any proceedings therein.

      The  provisions  hereof  shall be  binding  upon and  shall  ensure to the
benefit of the Company and NSBDC and their respective successors and assigns.

      IN WITNESS WHEREOF the undersigned has duly executed this instrument as of
the 18th day of September, 1998.

$2,000,000  loan, it shall be enforced subject to the prior right of the bankers
for ITC Learning  Corporation to obtain full repayment of the obligations of the
Debtor under a guarantee to such  bankers for the  indebtedness  of ITC Learning
Corporation.

generality of the foregoing, the Secured Party may do any of the following:

      (a)   appoint  by   instrument   a  receiver,   receiver  and  manager  or
            receiver-manager  (the person so appointed is hereinafter called the
            "Receiver") of the  Collateral,  with or without bond as the Secured
            Party  may  determine,  and  from  time  to  time  in  its  absolute
            discretion remove such Receiver and appoint another in its stead:

            Collateral  with power to  exclude  the  Debtor,  its agents and its

            possession;

      (c)   preserve,   protect  and  maintain  the  Collateral  and  make  such

            in such manner, at such price as can be reasonably obtained therefor
            and on such terms as to credit and with such  conditions of sale and
            stipulations  as to  title or  conveyance  or  evidence  of title or
            otherwise as to the Secured Party may seem reasonable, provided that
            if any sale, lease or other disposition is on credit the Debtor will
            not be entitled to be credited  with the  proceeds of any such sale,
            lease or other  disposition  until the money  therefor  is  actually
            received; and

      (e)   exercise all of the rights and remedies of a secured parry under the

the Secured Party  hereunder,  and in addition  shall have power to carry on the
business of the Debtor and for such  purpose  from time to time to borrow  money
either  secured or  unsecured,  and if secured  by a  security  interest  on any
Collateral  such security  interest may rank before or PARI PASSU with or behind
any  Security  Interest,  and if it does not so specify such  security  interest
shall rank before the Security Interests.

11.3.  Subject to the claims,  if any, of the creditors of the Debtor ranking in
priority  to this  Agreement,  all  amounts  realized  from the  disposition  of
Collateral  pursuant to this Agreement will be applied as the Secured Party,  in
its absolute discretion, may direct as follows:

      (a)   in payment of all costs,  charges and expenses (including legal fees
            and  disbursements on a solicitor and his own client basis) incurred
            by the Secured Party in connection with or incidental to:

             (i)  the exercise by the Secured  Party of all or any of the powers
                  granted to it pursuant to this Agreement; and

                  Receiver of all or any of the powers granted to it pursuant to

<PAGE>

      (c)   in or toward payment to the Secured Party of all interest  remaining
            unpaid in respect of the Obligations.

      Subject to applicable  law and the claims,  if any, of other  creditors of
the Debtor, any surplus will be paid to the Debtor.

12.   DEFICIENCY

sufficient to pay the Obligations in full the Debtor will immediately pay to the
Secured Party the amount of such deficiency.

contracted  by it,  for  damages  to  persons or  property  or for  salaries  or

manage the  Collateral  upon entry,  as herein  provided,  nor shall the Secured
Party be liable to account as a mortgagee in possession  or for anything  except
actual  receipts or be liable for any loss on  realization or for any default or
omission for which a mortgagee in  possession  may be liable.  The Secured Party

Debtor nor shall the Secured Party,  in the case of  securities,  instruments or

appropriation as the Secured Party may see fit.

17.   WAIVER

      The Secured  Party may from time to time and at any time waive in whole or
in part any right, benefit or default under any clause of this Agreement but any
such waiver of any right, benefit or default on any occasion shall be deemed not
to be a waiver of any such right, benefit or default thereafter, or of any other
right,  benefit or  default,  as the case may be. No waiver  shall be  effective
unless it is in writing.

18.   NOTICE

      Notice  may be given to either  party by  sending  it by  prepaid  mail or
delivered  to the party for whom it is  intended,  at the  address of such party
provided  herein or at such  other  address  as may be given in  writing by such

      The Secured Party may grant extensions of time and other indulgences, take
and give up security, accept compositions,  compound,  compromise, settle, grant
releases and discharges,  refrain from  perfecting or maintaining  perfection of
security interests,  and otherwise deal with the Debtor,  account debtors of the
Debtor,  sureties and others and with Collateral and other security interests as
the Secured  Party may see fit without  prejudice to the liability of the Debtor
or the Secured Party's right to hold and realize on the Security Interests.

20.   NO MERGER

      This  Agreement  shall not operate so as to create any merger or discharge
of any of the  Obligations,  or of any  assignment  transfer,  guarantee,  lien,
contract,  promissory  note,  bill of exchange or security  interest of any form
held or which may hereafter be held by the Secured Party from the Debtor or from
any other person whomsoever. The taking of a judgment with respect to any of the
Obligations  will not operate as a merger of any of the  covenants  contained in
this Agreement.

and in any other security agreement held by the Secured Party from the Debtor or
any  other  person   whomsoever  to  secure  payment  and   performance  of  the
Obligations,  are cumulative and no right or remedy  contained herein or therein
is  intended  to be  exclusive  but each is in  addition to every other right or
remedy  contained  herein or  therein  or in any  existing  or  future  security
agreement  or now or  hereafter  existing at law,  in equity or by  statute,  or


                                       11

Interests. The Debtor expressly agrees that the assignee,  transferee or secured
party,  as the case may be,  shall have all of the  Secured  Party's  rights and
remedies  under  this  Agreement  and the Debtor  will not  assert any  defense,
counterclaim,  right of  set-off  or  otherwise  any  claim  which it now has or
hereafter  acquires  against the Secured  Party in any action  commenced by such
assignee,  transferee  or  secured  party,  as the case may be, and will pay the
Obligations to the assignee, transferee or secured party, as the case may be, as
the Obligations become due.

23.   SATISFACTION AND DISCHARGE

      Any partial  payment or  satisfaction of the Obligations or any ceasing by
the  Debtor to be  indebted  to the  Secured  Party  shall be deemed not to be a
redemption  or  discharge of this  Agreement.  The Debtor shall be entitled to a
release and discharge of this  Agreement upon full payment and  satisfaction  of
all  Obligations,  and upon  written  request by the  Debtor and  payment to the
Secured Party of a discharge fee to be fixed by the Secured Party and payment of

think  best,  without  prejudice  to or in any way  limiting  or  lessening  the
liability of the Guarantor under this guarantee.

      (3) THAT NSBDC  shall not be bound to exhaust  its  recourse  against  the
borrower or other parties or the securities it may hold before being entitled to
payment from the Guarantor under this guarantee.

      (4) THAT any loss of or in respect of  securities  received  by NSBDC from
the borrower or any other person whether  occasioned  through the fault of NSBDC
or otherwise  shall not  discharge pro tanto or limit or lessen the liability of
the Guarantor under this guarantee.

      (5) THAT this shall be a  continuing  guarantee  and shall  cover  present
liabilities (if any) of the borrower to NSBDC and all liabilities incurred after
the date hereof with  respect to the loan and royalty  agreement  referred to in
the letter form NSBDC to the Borrower dated  September 16, 1998, a copy of which
is attached and shall apply to and secure any ultimate  balance due or remaining

borrower  be a  partnership)  any  change or changes  in the  membership  of the

by the introduction of one or more other partners shall not affect or in any way
limit or lessen the  liability of the  Guarantor  hereunder  and this  guarantee
shall extend to the person,  firm or corporation  acquiring or from time to time
carrying on the business of the borrower.

      (7) THAT all moneys,  advances,  renewals and credits in fact  borrowed or

liabilities hereby guaranteed notwithstanding any incapacity, disability or lack
or  limitation  of  status  or of power  of the  borrower  or of the  directors,
partners or agents thereof,  or that the borrower may not be a legal entity,  or
any  irregularity,  defect or  informality in the borrowing or obtaining of such
moneys,  advances,  renewals  or  credits;  and  any  amount  which  may  not be
recoverable  from  the  Guarantor  on  the  footing  of  a  guarantee  shall  be
recoverable  from the Guarantor as principal debtor in respect thereof and shall
be paid to NSBDC after demand therefor as hereinafter provided.

      (8) THAT any  account  settled  or  stated  by or  between  NSBDC  and the

the  borrower's  assets  within the bulk transfer  provisions of any  applicable
legislation or any composition with creditors or scheme or  arrangements,  NSBDC
shall have the right to rank for its full claim and  receive  all  dividends  or

NSBDC, or any part thereof.

      (10) THAT the  Guarantor  shall make payment to NSBDC of the amount of the
liability of the Guarantor  forthwith  after demand  therefor is made in writing
and such demand shall be conclusively  deemed to have been effectually made when
an envelope  containing it addressed to the Guarantor at the last address of the
Guarantor known to NSBDC is deposited,  postage  prepaid and registered,  in the
Post Office and the liability of the Guarantor shall bear interest from the date
of such demand at the rate or rates then  applicable to the  liabilities  of the

securities of any kind (including without limitation guarantees and postponement
agreements  whether or not in the same form as this instrument) now or hereafter

Guarantor shall continue liable, up to the amount guaranteed,  less any payments
made by the  Guarantor,  for any  balance  which  may be  owing  to NSBDC by the
borrower;  and in the event of the  valuation by NSBDC of any of its  securities
and/or retention thereof by NSBDC, such valuation and/or retention shall not, as
between NSBDC and the Guarantor, be considered as a purchase of such securities,
or as payment or  satisfaction  or reduction of the  borrower's  liabilities  to
NSBDC, or any part thereof.

      (10) THAT the  Guarantor  shall make payment to NSBDC of the amount of the
liability of the Guarantor  forthwith  after demand  therefor is made in writing
and such demand shall be conclusively  deemed to have been effectually made when
an envelope  containing it addressed to the Guarantor at the last address of the
Guarantor known to NSBDC is deposited,  postage  prepaid and registered,  in the
Post Office and the liability of the Guarantor shall bear interest from the date

of such demand at the rate or rates then  applicable to the  liabilities  of the
borrower of NSBDC.


                                     PART II

      (11) THAT this  instrument  is in addition  and without  prejudice  to any
securities of any kind (including without limitation guarantees and postponement
agreements  whether or not in the same form as this instrument) now or hereafter
held by NSBDC.

      (12)  THAT  there  are  not  representations,   collateral  agreements  or
conditions  with  respect  to  this  instrument  or  affecting  the  Guarantor's
liability hereunder other than as contained herein.

      (13) THAT this  instrument  shall be construed in accordance with the laws
of Nova  Scotia,  and the  Guarantor  agrees  that any  legal  suit,  action  or
proceeding  arising out of or relating to this  instrument  may be instituted in
the courts of such province or territory,  and the Guarantor  hereby accepts and
irrevocably  submits to the  jurisdiction  of the said  courts and  acknowledges
their competence and agrees to be bound by any judgment  thereof,  provided that
nothing  herein  shall  limit  NSBDC's  right to bring  proceedings  against the
Guarantor elsewhere.

      (14) THAT this instrument  shall extend to and enure to the benefit of the
successor and assigns of NSBDC,  and shall be binding upon the Guarantor and the
heirs, executors, administrators and successors of the Guarantor.

                  payment of any other  obligation  of ITC Canada to  Wachovia
                  and,  following full satisfaction of such  obligations,  the
                  NSBDC  Security  may be enforced  to recover  payment of any
                  other portion of the NSBDC Debt remaining  after recovery by
                  NSBDC of the amounts  referred to in the  preceding  section
                  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
            Wachovia  Security  shall be dealt with  according to the  preceding
            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:

<PAGE>

            (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.

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,

                  or  Wachovia  pursuant  to the  NSBDC  Security,  NSBDC  Debt,
                  Wachovia Security or Wachovia Debt;

            (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
                  Debt and the NSBDC Debt  shared as set out in  section  3.1(b)

                  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.    PAYMENT ARRANGEMENTS

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

            other party to remove such  property and assets from the premises of
            ITC Canada at all reasonable  times without  interference,  provided
            that such other party shall promptly repair any damage caused to the
            premises by the removal of any such property or assets.

                   ITC LEARNING COMPLETES ASSET ACQUISITION

Herndon,  VA - ITC  Learning  Corporation  ("ITC")  announced  today that it has
completed the  acquisition of the assets of Mentor  Networks Inc.  ("Mentor") of
Halifax,  Nova  Scotia.  As  previously  announced,  Mentor  had been  placed in
Receivership  by its  secured  lender,  the  Nova  Scotia  Business  Development
Corporation ("NSBDC"). The purchase price of approximately US$2,000,000 includes
a  combination  of  cash  (approximately   US$700,000)  and  a  five  year  note
(approximately  US$1,300,000).  ITC has also  agreed to pay up to a  maximum  of
approximately  US$1,100,000  in certain  future  royalty  payments  based on the
ongoing  performance  of the  Mentor  assets.  Since  this  is an  international
transaction,  the five year note and  royalty  payments  are subject to relevant
exchange rates.

As  part  of  the  acquisition,  ITC  acquires  42  employees  (of  whom  34 are
technical/development  personnel),  seven PC Skills titles  associated  with the
Microsoft Office Suite(TM) of products,  three Call Center titles,  intellectual
property  rights to an  additional  25 soft skills  products,  and certain fixed
assets. The Halifax operations have been combined with ITC's Toronto-based sales
and  marketing  office  and  are  being  operated  by  ITC's  newly  formed  and
wholly-owned  subsidiary,  ITC Canada Limited.  With the expansion of ITC Canada
Limited, ITC has established a significant presence in Canada.

Carl D. Stevens,  President and CEO of ITC stated, "We have long recognized that
Mentor's capabilities and courseware are among the finest in the industry.  That
is what led us to establish a business relationship with Mentor over a year ago,
when we were  desirous  of  capitalizing  on  their  development  expertise  and
instructional  design to expand  ITC's  courseware  portfolio.  Not only do they
provide us with a family of PC skills  products that can be used for  electronic
performance support at the employee's desk, they have an award-winning family of
business  productivity  products,  such as "The Art of Customer  Service"  (call
center  training),  "Promises  that  Pay"  (debt  collections)  and "Ask for the
Business...and Get It" (telesales training).  The addition of these courses take
ITC  into  new  and  expanding  markets.  In  essence,  ITC  was  able to take a

<PAGE>

potentially  negative  receivership  situation and turn it into  something  very
positive for ITC and its customers and we are very excited about that."
