As a result of the Issuer's actions, the letter stated that CGI would not conduct a contested solicitation to support any alternative slate at the 2008 annual meeting. A copy of this letter is attached hereto as Exhibit G and is incorporated herein by reference. ITEM 5. INTEREST IN SECURITIES OF THE ISSUER.

The aggregate percentage of Shares beneficially owned by the Reporting Persons is based upon 29,877,059 Shares outstanding, which is the total number of Shares outstanding as of August 2, 2007 as reported in the Issuer's Quarterly Report, filed on August 9, 2007 on Form 10-Q, for the period ended June 30, 2007. (b) By virtue of investment management agreements with each of CMS, CSO and CLEX, CGI has the power to vote or direct the voting, and to dispose or direct the disposition, of all of the 2,592,608 Shares held by CMSF, the 365,180 Shares held by CSO and the 7,000 Shares held by CLEX. By virtue of his direct and indirect control of CGI, George E.

In addition to the Shares that they beneficially own without reference to these contracts, the Reporting Persons currently have long economic exposure to 1,192,250 Shares through such contracts. These contracts do not give the Reporting Persons direct 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 ------------------------------ --------------------- CUSIP NO. 398433102 SCHEDULE 13D PAGE 9 OF 12 PAGES ------------------------------ --------------------- such contracts or that may be held from time to time by any counterparties to such contracts.
