Attention:    Mr. Walter R. MacDonald
              Vice-President, Finance & CFO
              -----------------------------
Dear Sirs:

We refer to the letter  agreement date June 11, 1996 detailing a Credit Facility
made  available  to  Gandalf  Technologies  Inc.  by Royal  Bank of Canada  (the
"Agreement").  All capitalized terms and references herein have the same meaning
as those in the Agreement.  We also refer to a letter  agreement  dated November
18, 1996 between the Bank and the Borrower which waived certain  defaults of the
Borrower  pursuant to the  Agreement  and  detailed  related  amendments  to the
Agreement (the "Amending Agreement").

The Bank and the Borrower  hereby  acknowledge the breach by the Borrower of the
Agreement and the Amending  Agreement in relation to Sections  23(a),  23(b) and
24(h) for the reporting  period ended  December 28, 1996. The Bank hereby waives
its rights in respect of such breaches for the period December 28, 1996 to March
31, 1997. This waiver is granted only in respect of the aforementioned  breaches
and only for the  aforementioned  period and is subject to and conditional  upon
the following:

     i. The Borrower will provide to the bank,  within 5 days hereof, a forecast
        of cash flow and  Margin  Requirement,  prepared  in a weekly  format to
        March  31,  1997  inclusive.  The  forecast  will be  delivered  in both
        consolidated and non-consolidated versions.

   ii.  The  Borrower  will  provide  to the  Bank,  by  Tuesday  of  each  week
        commencing February 4, 1997, with evidence of compliance with the Margin
        Requirements together with supporting documentation as required.

  iii.  The Borrower  will provide to the Bank,  within 15 calendar days of each
        month end,  consolidated,  rolling sales forecast for the current fiscal
        quarter with comparisons to the previous fiscal quarter.

   iv.  The Borrower  will provide to the Bank,  within 5 days hereof,  evidence
        satisfactory  to the Bank of the  engagement  of an  investment  banking
        firm,  chosen  by the  Borrower,  together  with a related  schedule  of
        activities  targeted to provide the Borrower with a cash infusion of not
        less than CDN $20 million by no later than March 31, 1997 (the  "Funding
        Arrangement"). If, in the Bank's sole opinion, there is material adverse
        change in the scope or timing of the Funding Arrangement,  the Bank may,
        at its option, declare Borrowings in default,  notwithstanding any other
        terms herein.

    v.  The borrowing spreads detailed in Section 6 (2) (a), (b) and (d) of the 
        Agreement are increased to 1.75% pending full compliance with the 
        Agreement.

   vi.  The Borrower  will pay to the Bank a risk premium equal to 1% per annum,
        calculated and payable monthly in arrears, of the amount committed under
        Segment 2(a) of the  Agreement,  until the earlier of Tangible Net Worth
        exceeding US $40,000,000  or the company  recording net after tax profit
        of $1,000,000 or more in any fiscal quarter.

  vii.  Acceptance of similar terms and conditions (with the specific  exception
        of (iv)  above) by GDCL with  respect to a credit  facility  extended to
        GDCL by the Bank's office in London, England.

 viii.  Suspension of Segment (1) of the Agreement with respect to FEF 
        Contracts.

All other terms and conditions of the Agreement remain unchanged.

Please  confirm your  acceptance  by signing and  returning the enclosed copy of
this letter no later than February 19, 1997.

 Yours truly,
S/J.L. (JIM) BLATTMAN
