the funding to complete the
Reorganization, upon the closing of the Equity Funding, Nuinsco shall be issued purchase
warrants (each a Warrant) of Campbell equal to 20% of the number of Common Shares
outstanding after giving effect to the Equity Funding, with each Warrant entitling Nuinsco to
purchase one Common Share at an exercise price of $0.10 per share exercisable until the second
anniversary of the closing of the Equity Funding. Nuinsco shall agree to refrain from voting
Common Shares representing more than 19.9% of the issued and outstanding Common Shares at any
meeting of the shareholders of Campbell in the event that the Toronto Stock Exchange requires
such undertaking as a condition to approving the issuance of such Warrants and/or the
underlying Common Shares. If such Exchange requires the shareholders of Campbell to approve

any other Common Shares issuable pursuant to this letter, Campbell shall present such matter
to its shareholders at the next shareholders meeting and shall recommend that shareholders vote
in favour of such matter. The proceeds from the exercise of the Warrants shall be used to
repay the Corner Bay Loan to the extent the same is outstanding at the time of any exercise of
any of the Warrants.

Corner Bay Property, free and clear of all liens, encumbrances, royalties and other interests
whatsoever (other than a 2% net smelter return royalty payable in respect of sales exceeding
750,000 tons of ore and the encumbrances created pursuant to the Corner Bay Loan). The Corner
Bay Loan will be repaid out of the first project cash flow from the
Corner Bay Property and the
balance of the  cashflow, after retention of mutually agreeable working capital, shall be shared
equally between Campbell and Nuinsco. Prior to the transfer of the
Corner Bay Property, Nuinsco
and Campbell shall form a joint venture and execute a joint venture agreement respecting their
ownership and operation of the Corner Bay Property (including the use of the proceeds of the
Corner Bay Loan, if any), on mutually acceptable terms and conditions. The proceeds of the
Corner Bay Loan shall be deposited in the joint ventures bank account.
