                                  INSTRUCTIONS

1.       DELIVERY OF LETTER OF TRANSMITTAL

         (a)      This Letter of Transmittal, properly completed and signed,
                  must be received by the Trustee, Clarica Trust Company, at its
                  office specified below at or prior to 8:00 p.m. (EST) on the
                  Expiry Date (as defined in the Offer) (currently Monday, April
                  7, 2003, but subject to extension at the discretion of the
                  Offeror).

         (b)      The method used to deliver this Letter of Transmittal is at
                  the option and risk of the Plan participant, and delivery will
                  be deemed effective only when this Letter of Transmittal is
                  actually received as indicated above. The Offeror recommends
                  that this Letter of Transmittal be hand delivered or couriered
                  to the Trustee, Clarica Trust Company, at its office specified
                  below and that a receipt therefor be obtained; otherwise, the
                  use of registered mail with return receipt requested, properly
                  insured, is recommended.

2.       SIGNATURES

                  This Letter of Transmittal must be completed and signed by the
Plan participant accepting the Offer or by such Plan participant's duly
authorized representative (in accordance with Instruction 3 below).

3.       FIDUCIARIES, REPRESENTATIVES AND AUTHORIZATIONS

                  Where this Letter of Transmittal is executed by a person
acting as an executor, administrator, trustee, guardian, attorney-in-fact, agent
or any other representative or fiduciary capacity, this Letter of Transmittal
must be accompanied by satisfactory evidence/proof of his or her appointment and
authority to act. Any of the Offeror, the Trustee or the Depositary, at its sole
discretion, may require additional evidence of appointment and authority to act.

4.       PARTIAL TENDERS

                  If less than all of the Emco Shares held by the Trustee on
behalf of the Plan participant pursuant to the Plan are to be deposited into the
Offer, fill in the number or percentage of Emco Shares to be deposited in the
appropriate space in Section 1 of this Letter of Transmittal. In such case, the
Emco Shares not deposited will continue to be held in the Plan. The total number
of Emco Shares held by the Trustee on behalf of the Plan participant will be
deemed to have been deposited unless otherwise indicated.

5.       SUBSTITUTE FORM W-9

                  Each U.S. Plan participant is required to provide the Trustee
and the Depositary with a correct Taxpayer Identification Number ("TIN") on the
Substitute Form W-9 which is provided in Block B, and to certify whether such
Plan participant is subject to backup withholding of United States federal
income tax. If a U.S. Plan participant has been notified by the Internal Revenue
Service that such Plan participant is subject to backup withholding, such Plan
participant must cross out item 2 of the Substitute Form W-9, unless such Plan
participant has since been notified by the Internal Revenue Service that such
Plan participant is no longer

                                      -ii-

subject to backup withholding. Failure to provide the information in the
Substitute Form W-9 may subject a U.S. Plan participant to 30% United States
federal income tax withholding on the payment of the purchase price of all Emco
Shares purchased from such Plan participant. If a U.S. Plan participant has not
been issued a TIN and has applied for one or intends to apply for one in the
near future, such Plan participant should write "Applied For" in the space
provided for in the TIN in the Substitute Form W-9, and sign and date the
Substitute Form W-9. If "Applied For" is written in the Substitute Form W-9 and
the Trustee and the Depositary are not provided with a TIN within 60 days, the
Trustee and the Depositary will withhold 30% of all payments of the purchase
price to such Plan participant until a TIN is provided to the Trustee and the
Depositary.

6.       MISCELLANEOUS

         (a)      No alternative, conditional or contingent deposits of Emco
                  Shares held pursuant to the Plan will be accepted. All
                  depositing Plan participants by execution of this Letter of
                  Transmittal waive any right to receive any notice of
                  acceptance of the Purchased Shares for payment.

         (b)      The Offer and any agreement resulting from the acceptance of
                  the Offer will be construed in accordance with and governed by
                  the laws of the Province of Ontario and the laws of Canada
                  applicable therein. The Plan participant signing this Letter
                  of Transmittal hereby unconditionally and irrevocably attorns
                  to the jurisdiction of the courts of the Province of Ontario.
