This Amendment No. 8 also constitutes an "exit filing" for the Reporting Persons, who do not intend to file any further amendments to the Schedule 13D. ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION. The second sentence of item 3 of the Schedule 13D is hereby amended as follows: A total of approximately $46 million was paid to acquire the Shares reported herein. ITEM 5. INTEREST IN SECURITIES OF THE ISSUER. Item 5 of the Schedule 13D is hereby amended and restated as follows: (a) As of the close of business on August 26, 2008, the Reporting Persons beneficially owned an aggregate of 1,505,476 Shares, constituting approximately 4.99% of the Shares outstanding. The aggregate percentage of Shares beneficially owned by the Reporting Persons is based upon 30,186,433 Shares outstanding, which is the total number of Shares outstanding as of July 31, 2008 as reported in the Issuer's Quarterly Report, filed on August 11, 2008 on Form 10-Q, for the period ended June 30, 2008. (b) By virtue of investment management agreements with each of CMS and CMAG, CGI has the power to vote or direct the voting, and to dispose or direct the disposition, of all of the 566,030 Shares held by CMSF and the 939,446 Shares held by CMAG. By virtue of his direct and indirect control of CGI, George E. Hall is deemed to have shared voting power and shared dispositive power with respect to all Shares as to which CGI has voting power or dispositive power. Accordingly, CGI and George E. Hall are deemed to have shared voting and shared dispositive power with respect to an aggregate of 1,505,476 Shares. (c) Information concerning transactions in the Shares effected by the Reporting Persons during the past sixty days is set forth in Schedule B hereto and is incorporated herein by reference. Unless otherwise indicated, all of such transactions were effected in the open market. (d) No person other than the Reporting Persons is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Shares. (e) Agust 26, 2008. ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OF RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER. Item 6 of the Schedule 13D is hereby amended and restated as follows: The Reporting Persons may, from time to time, enter into and dispose of cash-settled equity swap or other similar derivative transactions with one or more counterparties that are based upon the value of Shares, which transactions may be significant in amount. The profit, loss and/or return on such contracts may be wholly or partially dependent on the market value of the Shares, the relative value of Shares in comparison to one or more other financial instruments, indexes or securities, a basket or group of securities in which Shares may be included, or a combination of any of the foregoing. In addition to the Shares that they beneficially own without reference to these contracts, the Reporting Persons currently have short economic exposure to 144,137 Shares through such contracts. Such contracts do not give the Reporting Persons direct ------------------------------ -------------------- CUSIP NO. 398433102 PAGE 9 OF 11 PAGES ------------------------------ -------------------- or indirect voting, investment or dispositive control over any securities of the Issuer and do not require the counterparties thereto to acquire, hold, vote or dispose of any securities of the Issuer. Accordingly, the Reporting Persons disclaim any beneficial ownership in any securities that may be referenced in such contracts or that may be held from time to time by any counterparties to such contracts. Certain of the Reporting Persons are parties to exchange traded option agreements (the "Call Option Contracts"), that give a counterparty the right to purchase a total of 129,000 Shares from the Reporting Persons at prices ranging from $10.00 to $12.50 per Share, and can be exercised at any time prior to expiration dates ranging from September 20, 2008 to October 18, 2008. In addition, certain of the Reporting Persons are parties to exchange traded option agreements (the "Put Option Contracts") that (i) give the Reporting Persons the right to sell 2,500 Shares to a counterparty at a price of $12.50 per Share, and (ii) give a counterparty the right to sell 2,500 Shares to the Reporting Persons at a price of $12.50 per Share. The Put Option Contracts expire on September 20, 2008. Except as otherwise set forth herein, the Reporting Persons do not have any contract, arrangement, understanding or relationship with any person with respect to the securities of the Issuer. ------------------------------ -------------------- CUSIP NO. 398433102 PAGE 10 OF 11 PAGES ------------------------------ -------------------- SIGNATURE After reasonable inquiry and to the best of his or its knowledge and belief, each of the undersigned certifies that the information set forth in this statement is true, complete and correct.
