 CUSTOMER  ANNOUNCEMENT

Canvil’s phone lines have been answered as Anvil International Canada since mid-February as an initial customer notice that Canvil’s sales and distribution business will become Anvil International Canada on June 1, 2007. All orders placed for delivery after June 1, 2007 will be invoiced as Anvil International Canada. Please make adjustments within your AR and AP systems for this transition.

Canvil / Anvil International Canada is in the process of facility preparation in Edmonton, Montreal and Simcoe to accommodate the complete line of quality products manufactured by Anvil International, as well as the current product offering of welded and seamless pipe nipples and forged steel pipe fittings. Anvil International Canada will also be stocking a full line-up of Commercial and Industrial grade weld flanges and fittings. These additional product lines will be available to you this summer in all three locations.

Yours Sincerely
