  June&nbsp;1, 2010, Gerdau S.A. delivered a letter to the Board of Directors
  of the Issuer proposing to pursue a transaction (the &#147;Transaction&#148;) to
  acquire all of the Common Shares of the Issuer that it does not already own
  for $11.00 for each of the Common Shares, payable in cash.&nbsp; The Transaction values the Issuer&#146;s
  minority share capital at approximately $1.6 billion.</font></p>

  <p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">On
  June&nbsp;30, 2010, Gerdau S.A. and the Issuer announced that they had
  executed a definitive arrangement agreement (the &#147;Arrangement Agreement&#148;) to
  implement the Transaction by way of a &#147;plan of arrangement&#148; under the <i>Canada Business Corporations Act </i>(the &#147;Arrangement&#148;).&nbsp; The Arrangement Agreement and related press
  release are filed as Exhibits 1 and 2 to this Schedule 13D respectively.</font></p>
  <p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
  <p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">To
  be implemented, the Arrangement requires approval by two-thirds of the votes
  cast by holders of Common Shares. The Reporting Persons intend to vote all
  Common Shares held directly or indirectly by them in favor of the
  Arrangement. The Arrangement also will require approval by a simple majority
  of the votes cast by holders of Common Shares, other than Gerdau S.A., GSNAI,
  their respective directors and senior officers and any other &#147;related
  parties&#148;, &#147;interested parties&#148; and &#147;joint actors&#148;. In addition, the
  Arrangement will require approval by the Ontario Superior Court of Justice
  and is subject to certain customary conditions.</font></p>

  <p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The
  Issuer has called a special meeting of the holders of Common Shares to consider
  the Arrangement to be held on August&nbsp;10, 2010.&nbsp; The record date for determining
  shareholders entitled to vote and receive notice of the meeting is June&nbsp;18,
  2010.&nbsp; The Arrangement is expected to
  close in August&nbsp;2010.</font></p>

  <p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The
  Board of Directors of the Issuer established a special committee of
  independent directors (the &#147;Special Committee&#148;) in connection with the
  Transaction.&nbsp; The Special Committee
  engaged RBC Dominion Securities Inc. to perform a formal valuation of the
  Common Shares in accordance with Multilateral Instrument 61-101 of the
  Ontario Securities Commission and the </font><font size="2" style="font-size:10.0pt;">Quebec Autorit&#233; des march&#233;s financiers </font><font size="2" style="font-size:10.0pt;">and deliver a fairness
  opinion.&nbsp; On June&nbsp;1, 2010, RBC
  delivered its formal valuation and its written opinion to the Special
  Committee to the effect that the consideration to be received under the
  Arrangement is fair, from a financial point of view, to the holders of Common
  Shares (other than Gerdau S.A., GSNAI and their affiliates).</font></p>
  <p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
  <p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The
  Arrangement has been approved unanimously by the Board of Directors of the
  Issuer (with the representatives of Gerdau S.A. declaring their interests in
  the transaction and abstaining from voting) following the report and
  unanimous recommendation of the Special Committee.&nbsp; In doing so, the Board of Directors of the
  Issuer determined that the Arrangement is fair to the shareholders of the
  Issuer (other than Gerdau S.A. and its related parties) and is in the best
  interests of the Issuer. The Board of Directors of the Issuer also determined
  unanimously (with the representatives of Gerdau S.A. declaring their
  interests in the transaction and abstaining from voting) to recommend to the
  shareholders of the Issuer (other than Gerdau S.A. and its related parties)
  that they vote their Common Shares in favor of the Arrangement.</font></p>

  <p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Upon completion of the
  Arrangement, Gerdau S.A. would expect to (i)&nbsp;make changes to the
  Issuer&#146;s board of directors, management structure and capitalization,
  (ii)&nbsp;delist the Issuer from the Toronto Stock Exchange and New York
  Stock Exchange, (iii)&nbsp;apply to the Canadian securities regulatory
  authorities to have the Issuer cease to be a reporting issuer for purposes of
  applicable Canadian provincial and territorial securities laws,
  (iv)&nbsp;deregister the Issuer as a reporting company under the Securities
  Exchange Act of 1934 and (v)&nbsp;take other actions consistent with the
  Issuer becoming a wholly-owned subsidiary.</font></p>
