         Amendment to First Restated Credit Agreement dated as of January 27,
         1998, (b) a Second Amendment to First Restated Credit Agreement dated
         as of February 25, 1998, and (c) a Third Amendment to First Restated

         herein with their initial letter capitalized shall have the meanings
         assigned to such terms in the Credit Agreement.

Gentlemen:

     1. Emigration Transactions. You have advised the Banks that the Credit
Parties propose to take the following actions:

     a. Domestication. Parent will change its domicile from Canada to Delaware
by means of a domestication (the "Domestication") under Section 388 of the
Delaware General Corporation Law, and simultaneously therewith Parent will apply
for a Certificate of Discontinuance under Section 188(7) of the Canadian
Business Corporation Act. Pursuant to the Domestication, Parent's corporate
existence will be continued in the State of Delaware, and Parent will remain
liable for all of its obligations under the Credit Agreement, the Facility
Guaranty, the Parent Pledge Agreement and each of the other Loan Papers; and

     b. Borrower Merger. Immediately following the Domestication, Borrower will
merge with and into Parent with Parent being the surviving corporation (the
"Borrower Merger") and pursuant to the Borrower Merger, the outstanding capital
stock of Borrower (the "Borrower Stock") will be canceled.

     The Domestication and the Borrower Merger are collectively referred to
herein as the "Emigration Transactions").

     2. Restrictions in Credit Agreement; Request for Consent and Waiver and
Release of Stock Pledge. The Emigration Transactions are prohibited pursuant to
certain provisions of the Credit Agreement, including Section 9.4 thereof and
constitute an Event of Default under Section 11.1(k) of the Credit Agreement.
The Credit Parties have requested that the Banks consent to the Emigration
Transactions and waive Sections 9.4 and 11.1(k) of the Credit Agreement and any
other provisions of the Credit Agreement and the other Loan Papers to the extent
that the Emigration Transactions violate such provisions or result in a Default
or Event of Default under the Credit Agreement or the other Loan Papers. The
Credit Parties have further requested that simultaneously with the Borrower
Merger, Administrative Agent release the Borrower Stock from the Lien of the
Parent Pledge Agreement.

     3. Consent and Waiver; Agreement to Release Stock Pledge. Subject to and
upon the terms and conditions set forth herein, and in reliance on the
representations and warranties set forth herein, (a) the Banks (i) consent to
the consummation by the Credit Parties of the Emigration Transactions and waive
compliance by the Credit Parties with each provision of the Credit Agreement and
the other Loan Papers to the extent, but only to the extent, that the Emigration
Transactions violate such provisions or result in a Default or Event of Default
under the Credit Agreement or the other Loan Papers, and (ii) authorize and
instruct Administrative Agent to release the Borrower Stock from the Lien of the
Parent Pledge Agreement simultaneously with Borrower Merger, and (b)
Administrative Agent hereby agrees to release the Borrower Stock from the Parent
Pledge Agreement as provided in clause (a)(ii) of this Section 3.

                                   -1-



     4. Certain Terms and Conditions. The consent and waiver herein granted are
subject to each of the following terms and conditions:

     a. Execution of Amendment to Credit Agreement and Loan Papers. Immediately
following the Borrower Merger, Parent, Administrative Agent and Banks shall
enter into a Fourth Amendment to First Restated Credit Agreement (the "Fourth
Amendment") substantially in the form of Exhibit A hereto pursuant to which (i)
Parent will confirm its assumption of all liabilities and obligations of
Borrower under the Credit Agreement and the other Loan Papers, and (ii) the
Credit Agreement will be amended to reflect the consummation of the Emigration
Transactions.

     b. Delivery of Certain Documents. Immediately following the Borrower
Merger, Parent shall deliver or cause to be delivered to Administrative Agent
