3. Term of Option. The term of the Option shall commence at the Grant Date and, unless earlier terminated in accordance with Section 7 hereof, shall expire ten (10) years from the Effective Time.

4. Right to Exercise. Unless terminated as hereinafter provided, the Option shall become exercisable only as follows:

(a) The Optionee shall earn the right to exercise the Option, provided, that (i) the Optionee shall have remained in the continuous employ of the Company, through the date of a Liquidity Event, and (ii) the Company shall have achieved specified performance targets with respect to the multiple of invested capital (“MOIC”) for such Liquidity Event as such targets are attached hereto as Attachment A. Any units as to which Optionee does not earn the right to exercise the related Option prior to the expiration date set forth in Section 3 hereof shall thereupon expire and terminate; provided, however, that if the Optionee’s employment is terminated without Cause or for Good Reason during the Employment Period, as such terms are defined in the Optionee’s Employment Agreement with the Company and Graham Packaging Company, L.P., effective as of May 5, 2009 (the “Employment Agreement”), and a Liquidity Event occurs within one year of such termination of employment, then the Options shall become immediately exercisable upon such Liquidity Event.

(b) Optionee shall be entitled to the privileges of ownership with respect to the Units purchased and delivered to Optionee upon the exercise of all or part of this Option, subject to Section 8 hereof.

6. Notice of Exercise; Payment.

(a) To the extent then exercisable, the Option may be exercised in whole or in part by written notice to the Company stating the number of Units for which the Option is being exercised and the intended manner of payment. The date of such notice shall be the exercise date. Payment equal to the aggregate Exercise Price of the Units being purchased pursuant to an exercise of the Option must be tendered in full with the notice of exercise to the Company as provided in the Plan.

(b) As soon as practicable upon the Company’s receipt of Optionee’s notice of exercise and payment, the Company shall direct the due issuance of the Units so purchased.

7. Termination of Agreement. The Agreement and the Option granted hereby shall terminate automatically and without further notice on the earliest of the following dates:

(a) Subject to Section 4(a), After Optionee’s termination of employment for any reason, all unvested Options will be forfeited immediately, and all vested Options shall remain exercisable until the lesser of (i) ninety (90) days following the Optionee’s date of termination or (ii) the remaining term of the Option; provided, however, if the Optionee is terminated for Cause, as defined in an employment agreement between the Company and the Optionee, all vested and unvested Options will be forfeited immediately and terminate; or

(b) Ten (10) years from the Effective Time.

In the event that Optionee’s employment is terminated for Cause as described in Section 7(a) hereof, this Agreement shall terminate at the time of such termination notwithstanding any other provision of this Agreement and Optionee’s Option will cease to be exercisable to the extent exercisable as of such termination and will not be or become exercisable after such termination.

(b) If and to the extent the Options remain exercisable following the Optionee’s termination of employment, as provided in Section 7, the Company shall, after an Optionee’s employment has terminated for any reason, have the right and option to purchase and if the Company exercises such right each Optionee shall be required to sell to the Company, any or all of his or her then outstanding Options at a price per Option equal to the product of the (i) the excess of Fair Market Value over the Exercise Price, and (ii) the number of Units for which such Option was exercisable.

(d) The Company shall have the right to assign any or all of its rights to purchase Options and/or Units pursuant to this Section 8; provided, however, that the assignee of such rights may purchase Options and/or Option Units only by delivery of a cashier’s check or a certified check.

If at any time the Company elects to purchase any Units pursuant to Section 8 hereof, the Company shall pay the purchase price for such Units, by the Company’s delivery of a bank cashier’s check or certified check; provided that if a Financing Default exists or, after giving effect to such payment (including any distribution or loan from an affiliate of the Company to the Company in connection therewith) would exist, which prohibits such cash payment, the portion of the cash payment so prohibited (which may not exceed 55% of the excess of the purchase price over the Exercise Price (such excess being the “Spread”)) shall be made, to the extent such payment is not prohibited by a Financing Default or would not result (after giving effect to any distributions or loans from an affiliate of the Company to the Company in connection therewith) in a Financing Default, by the Company’s delivery of a junior subordinated promissory note (which shall be subordinated and subject in right of payment to the prior payment of all indebtedness of the Company) of the Company (a “Junior Subordinated Note”) in a principal amount equal to the amount of the purchase price which cannot be paid in cash (which may not exceed 55% of the Spread), payable in up to five equal annual installments commencing on the first anniversary of the issuance thereof and bearing interest payable annually at the prime rate listed in the Wall Street Journal (“WSJ”) on the date of issuance.
