1.       (1)     Subject to the terms and conditions set out in this Agreement
                 and a commitment letter dated December 23, 1997 (the
                 "COMMITMENT LETTER"), the Lenders hereby replace the existing
                 line of credit (if any) previously granted to the Borrower
                 with a new revolving line of credit (the "LINE OF CREDIT"),
                 and all advances under this line of credit shall at all times
                 be subject to the terms and conditions of this Agreement.

         (2)     Subject to subsection (1) hereof and to any considerations of
                 precedent lending practice, the Lenders shall advance funds
                 under the Line of Credit as requested by the Borrower from
                 time to time, but in no event shall the aggregate amount
                 advanced and outstanding at one time exceed EIGHT HUNDRED
                 THOUSAND DOLLARS ($800,000).

         (3)     Despite subsection (2) hereof, the Lenders and the Borrower
                 may from time to time enter into negotiations to amend the
                 Line of Credit, and any such amendment shall be in writing
                 signed as provided in subsection 8(3) hereof and shall be
                 subject to the terms and conditions of this Agreement and any
                 amendments in writing thereto.

         (4)     All amounts advanced to the Borrower by the Lenders that are
                 outstanding as of the date hereof under any previous line of
                 credit agreement between the Lenders and the Borrower shall be
                 deemed to be demand advances under this Agreement.

         (5)     The obligations of the Lenders to advance funds or provide
                 other credit facilities under the terms of this Agreement
                 shall be conditional upon the Lenders having received:

                                  in each case certified by the Chief Executive
                                  Officer or Treasure of the Borrower to be 
                                  true and to remain in full force and effect 
                                  unamended, as of the date of the certificate;

                          form;

                 (c)      the most recent minimum review level financial

                          Officer of the Borrower, and

                 (e)      a certificate of the Chief Financial Officer of the
                          Borrower that, after making due inquiry, he has
                          determined that there has been no material adverse
                          change since the date of the most recently audited
                          financial statements of the Borrower.

2.       (1)     All funds advanced to the Borrower shall be advanced on a
                 demand loan basis and the following rules shall apply in case
                 of such advances:

                 (a)      The Borrower shall pay the Lenders interest at an
                          annual rate of PRIME plus 1.75%, upon any amount
                          advanced and outstanding, and upon any arrears of
                          interest.

                          "PRIME" shall mean the annual rate of interest which
                          CUCO establishes as the reference rate of interest to
                          determine interest rates it will charge at such time
                          for demand loans in Canadian dollars and which it
                          refers to as its special rate of interest, such rate
                          to be adjusted automatically and without the
                          necessity of any notice to the Borrower upon each
                          change to such rate.

                 (b)      Interest shall be payable under subsection 2. (1) (a)
                          herein on any amount outstanding hereunder on the
                          last day of each month, or at the time of repayment,
                          if repayment is made before an interest payment date.

                 (c)      Interest shall be payable by the Borrower for the day
                          on which an advance is made but shall not be payable
                          for the day on which repayment is made, if the
                          Lenders were notified of the intended repayment by
                          12:00 noon (Toronto time) on the day prior to the day
                          on which the repayment is made, provided the advance
                          is in fact repaid by the close of banking business in
                          Toronto on the day specified for the repayment.

                 (d)      The Borrower shall repay the Lenders the amounts
                          advanced from time to time on demand together with
                          all interest owing thereon in the manner as provided
                          in this Agreement, but the Borrower may at any time
                          repay to the Lenders all or any part of the money due
                          hereunder.

                 (e)      All interest payable to the Lenders under this
                          Agreement shall be received by the Lenders free and
                          clear of all taxes or duties imposed by or under the
                          laws of Canada, and province thereof or any other
                          jurisdiction, and without limiting the foregoing any
                          withholding tax, value added tax, business transfer
                          tax, sales tax or other tax levied on interest
                          payable which would adversely affect the net interest
                          received by the Lenders shall be paid by the Borrower
                          respectively, and not the Lenders, save and except
                          for taxes on the income or on the capital of the
                          Lenders which shall be the Lenders' responsibility.

                 (f)      Advances to the Borrower under this agreement may be
                          made by way of overdraft in the Borrower's current
                          account with the Credit Union or by making payment
                          upon a cheque or other bill of exchange drawn by the
                          Borrower on the Credit Union.

3.       (1)     All payments to be made by the Borrower to the Lenders shall
                 be made by depositing the same for credit into the account
                 maintained by the Borrower with the Credit Union for operating
                 the line of credit, or with any such other depository at such
                 other place or places as the Lenders may, by writing, direct.

         (2)     Where a payment is received by the Lenders from the Borrower,
                 the Lenders may elect whether to apply that payment first
                 towards the interest with the remainder, if any, applied to
                 the line of credit balance, or to apply that payment towards
                 the reduction of the line of credit balance first.

         (3)     The records and book maintained by the Lenders in the usual
                 and ordinary course of its business that touch or concern the
                 state of accounts between the parties hereto shall be prima
                 facie evidence of the true state of accounts between the
                 parties for all purposes including litigation.

4.       The Borrower specifically and expressly covenants with the Lenders as
         follows:

         (a)     The Borrower shall provide the Lenders:

                 (i)      with a certified copy of its consolidated (where
                          applicable) and non-consolidated minimum review level
                          Year End Financial Statements for each fiscal year
                          within ninety (90) days of the end of its fiscal
                          year, including its balance sheet, statement of
                          income and disbursements, statement of surplus and
                          statement of changes in financial position; and

                                                                          Page 5


                 (ii)     reasonable access to the offices, books and records
                          of the Borrower, for the purpose of determining the
                          value of the security pledged or given to the
                          Lenders.

         (b)     Where the amount advanced and outstanding under this Agreement
                 exceeds seventy percent (70%) of the funds available to the
                 Borrower, the Borrower shall not:

                 (i)      borrow any additional funds of money from any other
                          financial institution; or

                 (ii)     make a loan or other advance which will place it in a
                          deficit which exceeds its available line of credit
                          under this Agreement;

                 unless it gives the Lenders prior notice of its intent to do
         so.

5.       The Borrower shall draw, execute and deliver at its own expense, all
         such instruments and documents, and do all such acts and things as the
         Lenders may from time to time reasonably consider necessary or
         advisable for the purpose of carrying out the intent and provisions of
         this Agreement.

6.       (1)     All advances hereunder shall be secured by a General Security
                 Agreement in the Lenders' form, executed and delivered by the
                 Borrower to the Lenders and such General Security Agreement
                 shall be a first charge in favour of the Lenders except as
                 otherwise provided for in the Commitment Letter, and the
                 Borrower shall not enter into any new borrowing with any
                 creditor after the date of this Agreement which would afford
                 that creditor priority over the claims of the Lenders under
                 this Agreement, or grant any creditor any new or further
                 security in respect of any existing indebtedness, and the
                 Borrower shall discharge or postpone any security now held by
                 any other creditor or person that exists or may exist in
                 priority to the security given under this Agreement, except
                 for security in favour of Ontario Development Corporation,
                 Laurentian Bank of Canada and First Ontario Labour Sponsored
                 Investment Fund.

         (2)     The Borrower indemnifies the Lenders with interest at the rate
                 set above for all payments, costs, charges, legal fees and
                 other expenses paid or incurred by the Lenders in connection
                 with the authority of this Agreement or in connection with any
                 claim, suit, action or other proceeding brought against the
                 Lenders by reason of this Agreement.

7.       (1)     All money due from the Borrower to the Lenders by reason of
                 any advances under the revolving line of credit, whether as to
                 principal, interest or otherwise under this Agreement, and all
                 money advanced and outstanding, under this or any other
                 agreement between the Lenders and the Borrower, shall become
                 due and payable

                                                                          Page 6

                 upon demand in the event that the Borrower defaults on, or is
                 otherwise in breach of this Agreement or the General Security
                 Agreement.

         (2)     The Borrower shall have seven (7) days from the date of demand
                 to remedy the breach or default and in the event that the
                 breach or default is nor remedied within the seven (7) day
                 period, all money advanced and outstanding, under this or any
                 other agreement plus the full amount of all interest and other
                 sums as provided above in subsection (1) shall become due and
                 payable without further demand.

8.       (1)     Subject to this section, the term of this Agreement shall be
                 for a period of one (1) year from the date of this Agreement.

         (2)     The Borrower may apply to the Lenders to renew this Agreement
                 for a period of twelve (12) months next following the date on
                 which this Agreement would otherwise terminate and where the
                 Lenders agree to such a renewal, this Agreement shall remain
                 in full force and effect, with the necessary modifications,
                 for the period of renewal so agreed between the parties.

         (3)     The renewal of this Agreement may be embodied in the form of
                 commitment letter addressed by the Lenders to the Borrower and
                 signed by each of the parties, and that letter,

                 (a)      may contain provisions adding to, deleting or
                          otherwise modifying any of the terms of this
                          Agreement; and

                 (b)      need not make any specific reference to this
                          Agreement,

                 and where such a letter is delivered by the Lenders to the
                 Borrower, the Lenders shall be deemed not to have agreed to
                 the renewal of this Agreement until such time as the Borrower
                 signs and returns a duplicate copy of the commitment letter
                 evidencing the consent of the Borrower to any amendment set
                 out in the commitment letter.

         (4)     Nothing in this section shall be so construed as to permit or
                 restrict the rights conferred upon the Lenders under this
                 Agreement to demand payment of, and recover, any amount
                 advanced on a demand basis or otherwise due and payable under
                 any provision of this Agreement.

         (5)     The expiry or other termination of this Agreement shall not
                 relieve the Borrower or the Lenders from any obligation that
                 arose prior to the date on which the Agreement expired.

9.       (1)     In addition to any interest payable under section 2, the
                 Borrower agrees to pay to the Lenders on demand all reasonable
                 legal fees and other reasonable costs or expenses
