Dear Mr. Hamilton:


As we have discussed, I have agreed to serve as a member of the Board of
Directors of Graham Packaging Company Inc., a Delaware corporation (the
"Company"), which will be the new name of GPC Capital Corp. II, upon
consummation of the reorganization contemplated in connection with its initial
public offering of common stock. I understand I will be elected as a director of
the Company immediately prior to the Company's initial public offering. I
consent to being named as a future Board member of the Company in the Form S-1
registration statement being filed in connection with the Company's initial
public offering and in the Form S-1 registration statement being filed in
connection with the offering of senior subordinated notes due 2008 to be issued
by Graham Packaging Company and GPC Capital Corp. I and guaranteed by the
Company.


Very truly yours,
