Item 4. Purpose of the Transaction ----------------------------------- Pursuant to the terms of an Underwriting Agreement, dated as of December 14, 2005 (the "Underwriting Agreement"), among the Issuer, Blum L.P., PB Capital and the underwriter party thereto, on December 20, 2005, Blum L.P. and PB Capital sold to such underwriter an aggregate of 2,667,257 shares of Common Stock at a price of $22.44 per share (net of underwriting discounts and commissions), in a public offering pursuant to the Issuer's Registration Statement on Form S-1 (Registration No. 333-117344) and the prospectus supplement dated December 14, 2005 filed by the Issuer with the Commission on December 16, 2005 (the "Offering"). Also pursuant to the Underwriting Agreement, Blum L.P. and PB Capital granted to such underwriter a 30-day option to purchase an aggregate of 400,089 additional shares of Common Stock, at a price of $22.44 per share (net of underwriting discounts and commissions), to cover any over-allotments. The information set forth in this Item 4 is qualified in its entirety by reference to the Underwriting Agreement (Exhibit A hereto), which is incorporated by reference herein in its entirety. CUSIP NO. 713-839108 SCHEDULE 13D Page 7 of 9 Item 5. Interest in Securities of the Issuer --------------------------------------------- Item 5 is hereby amended as follows: (a), (b) According to the Issuer's Prospectus Supplement filed with the Commission on December 16, 2005, there were 26,028,500 shares of Common Stock issued and outstanding as of December 2, 2005. Based on such information, after taking into account the transactions described in Item 5(c) below, the Reporting Persons report beneficial ownership of the following shares of Common Stock: (i) 399,227 shares of Common Stock held by Blum L.P. and RCBA Inc. on behalf of the limited partnership for which Blum L.P. serves as the general partner, which represents 1.5% of the outstanding shares of the Common Stock; and (ii) 49,801 shares of the Common Stock that are legally owned by United Brotherhood of Carpenters Pension Plan ("UBC") (the "Investment Advisory Client"), with respect to which Blum L.P. has voting and investment power. The Investment Advisory Client represents .2% of the outstanding shares of Common Stock. The Investment Advisory Client has entered into an investment management agreement with Blum L.P., but does not have any contract, arrangement or understanding with any other Reporting Person, with respect to the acquisition, ownership, disposition or voting of any shares of the Common Stock. The Investment Advisory Client disclaims membership in a group with any Reporting Person, and disclaims beneficial ownership of any shares beneficially owned by the Reporting Persons other than for their own account. Voting and investment power concerning the above shares are held solely by Blum L.P. The Reporting Persons therefore may be deemed to be members in a group, in which case the group would be deemed to have beneficial ownership of an aggregate of 449,890 shares of the Common Stock, which is 1.7% of the outstanding Common Stock. As the sole general partner of Blum L.P., RCBA Inc. is deemed the beneficial owner of the securities over which Blum L.P. has voting and investment power. The filing of this Schedule shall not be construed as an admission that any of the shareholders, directors or executive officers of RCBA Inc., is, for any purpose, the beneficial owner of any of the securities that are beneficially owned by RCBA Inc. c) The Reporting Persons effected the following transactions in the Common Stock during the 60 days prior to the filing of this Schedule 13D: On December 20, 2005, the Reporting Persons sold the following number of shares of Common Stock in the Offering for a price of $22.44 per share (net of underwriting discounts and commissions): Entity Trade Date Shares Price/Share ------ ---------- --------- --------- Blum L.P. and the investment 12-20-05 2,667,257 22.44 partnership for which Blum L.P. serves as the general partner. (d) Not applicable. (e) As of December 20, 2005, the Reporting Persons ceased to be beneficial owners of more than five percent of the Common Stock.
