                         AMENDMENT TO LOAN AGREEMENT


    WHEREAS ICHOR Corporation ("Ichor"), ICHOR Services, Inc. ("ISI") and
Drummond Financial Corporation (the "Lender") entered into a loan agreement
effective the 15th day of January, 1997 (the "Loan Agreement"), wherein Ichor
and ISI (collectively the "Borrowers") requested that a credit facility be
made available to them by the Lender and the Lender agreed to make the credit
facility available to the Borrowers upon the terms and conditions set out in
the Loan Agreement; and

    WHEREAS the Borrowers and the Lender desire to amend the Loan Agreement,
in accordance with section 1.3 thereof, to reflect a change in the Principal
Sum to be made available by the Lender to the Borrowers pursuant to such
credit facility and have agreed to enter into this amendment agreement (the
"Amendment Agreement").

NOW THEREFORE THIS AGREEMENT WITNESSES THAT in consideration of one dollar
($1.00) paid by the parties to each other, receipt of this sum being
acknowledged by each of the parties, and other good and valuable
consideration, the Borrowers jointly and severally covenant and agree with the
Lender and the Lender covenants and agrees with the Borrowers as follows:

1.   All capitalized terms used and not otherwise defined herein shall have
     the meanings assigned to them in the Loan Agreement.

2.   The definition of "Principal Sum" contained in section 1.1 of the Loan
     Agreement is hereby amended to delete the reference to "$250,000" and
     insert in its place "$750,000".

3.   The Lender and the Borrowers hereby confirm and ratify the Loan Agreement
     as amended and modified by this Amendment Agreement.

4.   Each of the Borrowers represents and warrants to the Lender as follows:

    (a)  each of the Borrowers has taken all necessary action to authorize the
         creation, execution, delivery and performance of this Amendment
         Agreement and this Amendment Agreement has been duly executed by the
         Borrowers, as required, and when delivered, will, together with the
         Loan Agreement and Ancillary Documents, constitute legal, valid and
         binding obligations of the Borrowers, enforceable in accordance with
         their terms;

    (b)  each of the Borrowers has to date fulfilled and will hereafter
         continue to fulfill each covenant, agreement and condition on its
         part to be performed under the Loan Agreement, as amended, and
         Ancillary Documents;

    (c)  neither of the Borrowers has knowledge of the existence of any event
         of default or any event which, upon notice or lapse of time or both,
         would become an event of default under the Loan Agreement, as
         amended; and

    (d)  neither of the Borrowers has entered into any amendment or supplement
         to the Loan Agreement other than this Amendment Agreement.

5.   This Amendment Agreement is declared to be supplemental to the Loan
     Agreement and is to form part of and shall have the same effect as though
     incorporated in the Loan Agreement.

6.   This Amendment Agreement may be executed in several parts in the same
     form and by facsimile, and such parts as so executed shall together
     constitute one original document, and such parts, if more than one, shall
     be read together and construed as if all the signing parties had executed
     one copy of this Amendment Agreement.

7.   This Amendment Agreement will enure to the benefit of and be binding upon
     the parties hereto and their respective successors and assigns.

IN WITNESS WHEREOF, the parties hereto have caused this Amendment to Loan
Agreement to be duly executed effective as of the date set out herein.
