THE INFORMATION BELOW SUPPLEMENTS THE INFORMATION PREVIOUSLY PROVIDED. Item 4. Purpose of Transaction On February?21, 2008, the Issuer entered into a Letter Agreement (the "Letter Agreement") with ValueAct Master Fund and ValueAct Master Fund III (together with their respective affiliates, the "ValueAct Parties"). Pursuant to the terms of the Letter Agreement, in consideration for certain restrictions and limitations to be placed on the ValueAct Parties as more fully described below, the board of directors of the Issuer (the "Board of Directors"), among other things, (i)?increased the size of the Board of Directors from eight to nine directors and filled the resulting vacancy with Jeffrey W. Ubben, chief executive officer, chief investment officer and a founder, of ValueAct Capital, who will serve on the Board of Directors until the 2008 annual meeting of stockholders of the Issuer (the "2008 Annual Meeting") and (ii)?nominated Mr.?Ubben for election as a director of the Issuer at the 2008 Annual Meeting. If at any time the ValueAct Parties cease to own more than five percent of the outstanding voting power of the Issuer, the ValueAct Parties' right to designate a director to serve on the Board of Directors pursuant to the terms of the Letter Agreement will terminate upon the request of the Board of Directors and the ValueAct Parties shall promptly cause Mr.?Ubben (or, if applicable, his successor director) to resign from the Board of Directors. Pursuant to the terms of the Letter Agreement, the Issuer agreed to appoint and nominate two duly qualified persons (each of whom shall meet the definition of independence as defined by the New York Stock Exchange) as members of the Board of Directors not later than the date of the 2008 Annual Meeting. Before making the appointments, the Issuer agreed to consult with Mr.?Ubben with respect to the identity, background, qualifications and independence of such persons. In consideration for the foregoing, the ValueAct Parties agreed, subject to certain exceptions, that until the date on which the 2009 annual meeting of stockholders of the Issuer (the "2009 annual meeting")is held, the ValueAct Parties will not (and will cause their representatives not to), among other things, (i)?acquire any securities of the Issuer or any property, asset or business of the Issuer, (ii)?propose any tender or exchange offer, merger, or other business combination involving the Issuer, or tender any voting securities of the Issuer into any such tender or exchange offer or vote any voting securities of the Issuer in favor of any such transaction, (iii)?make, or in any way participate in any solicitation of proxies to vote any voting securities of the Issuer (other than for a proposal supported by the Board) and (iv)?other than in a Rule 144 broker transaction, sell, transfer or otherwise dispose of any voting securities of the Issuer to any person who is (or will become upon consummation of such sale, transfer or other disposition) a beneficial owner of five percent or more of the outstanding voting securities of the Issuer. -------------------------- ------------------------- CUSIP NO. 681904108 Page 11 of 15 ----------------------------------------------------------------------------- Pursuant to the terms of the Letter Agreement, if the Issuer (acting through the Board of Directors) does not nominate Mr. Ubben or, if applicable, the Qualified ValueAct Designee (as such term is defined in the Letter Agreement) to stand for re-election as a director at the 2009 Annual Meeting, then the obligations of the ValueAct Parties under the Letter Agreement will terminate on the date that is 10 days before the latest date on which pursuant to the By-laws of the Issuer a stockholder of the Issuer may give a valid notice to the Issuer of such stockholder's intention to make a proxy solicitation or otherwise solicit proxies with respect to the election of a director at the 2009 Annual Meeting. The foregoing description of the Letter Agreement is qualified in its entirety by reference to the full text of the Letter Agreement, which is attached hereto as Exhibit (2) and incorporated herein by reference. Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer The information set forth in Item?4 above with respect to the Letter Agreement is incorporated herein by reference. Other than as described elsewhere in this Report and as previously reported, the Reporting Persons have no understandings, arrangements, relationships or contracts relating to the Issuer's Common Stock which are required to be described hereunder.
