(1)	In connection with the Issuer's initial public offering on July 25, 2006, the Issuer declared a stock dividend payable to the holders of record of the Issuer's Common Stock issued and outstanding on July 25, 2006 (the "Record Date.") The payment of such stock dividend was contingent upon whether the underwriters in the Issuer's initial public offering exercised their option to purchase up to an additional 1,875,000 shares of Common Stock (the "Over-Allotment Option") on or prior to August 24, 2006 (the "Expiration Date.") The underwriters did not purchase any of the 1,875,000 shares of Common Stock under the Over-Allotment Option prior to the Expiration Date, and on August 25, 2006, the Issuer distributed the stock dividend of 1,875,000 shares ratably to the holders of its Common Stock as of the Record Date. FR X Chart Holdings, LLC received 1,773,022 shares of the Issuer's Common Stock pursuant to this stock dividend.
(2)	Consists of the 12,376,214 shares of common stock held by FR X Chart Holdings LLC, and 7,998 aggregate restricted stock units granted to Messrs. Day, Guill and Moore as previously reported.
(3)	Each Reporting Person disclaims beneficial ownership of such securities except to the extent of its pecuniary interest therein. Additionally, pursuant to Rule 16a-1(a)(4) of the Securities Exchange Act of 1934, each Reporting Person states that this filing shall not be deemed an admission that such Reporting Person is the beneficial owner of any of the securities reported herein.
(4)	Other than the 7,998 restricted stock units granted to Messrs. Day, Guill, and Moore, these securities are directly owned by FR X Chart Holdings LLC ("Holdings"). Each of First Reserve GP X, Inc. ("GP X Inc."), First Reserve GP X, L.P. ("GP X"), and First Reserve Fund X, L.P. ("Fund X" and collectively with GP X Inc. and GP X, the "Fund Entities"), may be deemed to share beneficial ownership over all such securities. Fund X is the sole member of Holdings. GP X is the general partner of Fund X, and GP X Inc. is the general partner of GP X. The Fund Entities are entitled to a portion of the profits from the sale of Issuer securities held by Messrs. Day, Guill and Moore, and therefore the Fund Entities may be deemed to share beneficial ownership of the 7,998 restricted stock units.
