<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Mr.&nbsp;Schwartz,
through&nbsp;American Farm Investment Corporation (or&nbsp;a wholly-owned subsidiary), sold 700,008&nbsp;Subordinate Voting Shares on March&nbsp;8, 2000. The
sale by Mr.&nbsp;Schwartz was made pursuant to a Prospectus Supplement dated March&nbsp;1, 2000 (to&nbsp;a Prospectus dated February&nbsp;18, 2000) in which the Issuer offered
13,600,000&nbsp;Subordinate Voting Shares and the selling shareholders (including Mr.&nbsp;Schwartz) offered 6,400,000&nbsp;Subordinate Voting Shares. In a concurrent private placement, a
subsidiary of Onex Corporation (the&nbsp;"Onex Subsidiary") issued approximately $253.1&nbsp;million principal amount of exchangeable debentures due 2025. The exchangeable debentures are
exchangeable and redeemable for an aggregate of 5,548,320&nbsp;Subordinate Voting Shares, in certain circumstances, during their 25-year term. In connection with the exercise by a holder
of a debenture of its right to exchange the debentures for Subordinate Voting Shares, any redemption of the debentures at the option of the Onex Subsidiary or the repayment of the debentures at
maturity or following an event of default, the Onex Subsidiary may, at its option, satisfy its obligations by payment of a cash amount specified in the debentures, by delivery of Subordinate Voting
Shares at their then current market price or by any combination of cash and Subordinate Voting Shares. If the Onex Subsidiary does not have sufficient Subordinate Voting Shares, the requisite number
of Multiple Voting Shares held by the Onex Subsidiary will immediately be converted into Subordinate Voting Shares, which shares will be delivered on the exchange. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
a series of private placements, certain wholly-owned subsidiaries of Onex Corporation (collectively, the "Onex Subsidiary") issued approximately $362.3&nbsp;million principal amount
of exchangeable debentures due 2025. The exchangeable debentures are exchangeable and redeemable for an aggregate of 3,666,000&nbsp;Subordinate Voting Shares, in certain circumstances, during their
25-year term. In connection with the exercise by a holder of a debenture of its right to exchange the debentures for Subordinate Voting Shares, any redemption of the debentures at the

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
August&nbsp;16, 2000, a company controlled by Mr.&nbsp;Schwartz, Onex Corporation, a subsidiary of Onex Corporation and certain wholly-owned subsidiaries of Onex Corporation
(the&nbsp;"Schwartz Entities") each entered into an ISDA Master Agreement with Merrill Lynch Canada,&nbsp;Inc. ("Merrill") and each of the Schwartz Entities executed a confirmation thereto on
August&nbsp;17, 2000. At any time before February&nbsp;15, 2001, Merrill may purchase 715,055&nbsp;Subordinate Voting Shares at a forward price of CD$103.13 per Subordinate Voting Share
(the&nbsp;"Forward Price") for an aggregate purchase price of CD$73,743,622.15. On February&nbsp;15, 2001, the Schwartz Entities may deliver the Subordinate Voting Shares or they each may elect to
settle the trade with a cash payment (the&nbsp;"Cash Settlement"). If the closing price of the Subordinate Voting Shares on the Toronto Stock Exchange (the&nbsp;"Future Trading Price") is greater
than the Forward Price, the Schwartz Entities that elect the Cash Settlement agree to pay Merrill Lynch an amount in cash equal to the difference between the Future Trading Price and the Forward Price
multiplied by the number of Subordinate Voting Shares as to which the Cash Settlement election is made (the&nbsp;"Equity Amount"). If the Future Trading Price is less than the Forward Price, Merrill
has agreed to pay each Schwartz Entity that elects the Cash Settlement an amount in cash equal to the absolute value of the Equity Amount. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Except
as set forth in the immediately preceding paragraphs, Mr.&nbsp;Schwartz does not have any present plans or proposals that relate to or would result in: (a)&nbsp;the

liquidation, involving the Issuer or any of its subsidiaries; (c)&nbsp;a sale or transfer of a material amount of assets of the Issuer or of any of its subsidiaries; (d)&nbsp;any change in the
present board of directors or management of the Issuer, including any plans or proposals to change the number or term of such directors or to fill any existing vacancies on such board; (e)&nbsp;any

charter, by-laws or instruments corresponding thereto or other actions that may impede the acquisition of control of the Issuer by any person; (h)&nbsp;causing a class of securities of
the Issuer to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association;
(i)&nbsp;causing a class of equity securities of the Issuer becoming eligible for termination of registration pursuant to Section&nbsp;12(g)(4)&nbsp;of the Securities Exchange Act of 1934; or
