FORM OF AMENDED AND RESTATED OPTION UNIT AGREEMENT

1998 GRAHAM PACKAGING HOLDINGS COMPANY

MANAGEMENT OPTION PLAN

AMENDED AND RESTATED OPTION UNIT AGREEMENT

This AMENDED AND RESTATED OPTION UNIT AGREEMENT
(this Option Agreement), dated as of                     , is made by and between Graham Packaging Holdings Company, a
Pennsylvania limited partnership (the Company), and                      (the Grantee).

Pursuant to the 1998 Graham Packaging Holdings Company Management Option Plan (the Plan) (a copy of which is attached hereto and the
terms of which are hereby incorporated by reference), the Company intends to provide incentives to Eligible Individuals by providing them with opportunities for limited partnership interests in the Company.

Pursuant to that certain Option Unit Agreement (the Old Agreement), dated February 2, 1998, the Grantee was granted an option to
purchase Units of the Company and the term of such option shall expire on December 31, 2008.

The Committee has determined that it is
in the best interests of the Company and its equity holders to extend the term of such option for an additional ten (10) years.

The
Grantee understands and acknowledges that this Option Agreement amends and restates the Old Agreement in its entirety and that the Old Agreement is null and void.

In consideration of the mutual covenants herein contained and other good and valuable consideration, receipt of which is hereby acknowledged, the parties hereto do hereby agree as follows:

---

Article III.

EXERCISABILITY OF OPTIONS

3.1 Exercisability. Subject to Section 3.2 below, the Option
is fully vested and exercisable as of the date of this Agreement.

3.2 Timing of Exercise. The Option may only be exercised upon the
earlier of (i) a termination of the Grantees service with the Company, (ii) the occurrence of a Change of Control or a Sale of the Business (collectively, a Permissible Exercise Event), (iii) the Grantees
Disability, or (iv) the Grantees death; provided, however, that the Grantee is an employee or consultant on the date of such Change of Control or Sale of the Business.

Article IV.

EXERCISE OF THE OPTION

4.1 Right to Exercise. The Option granted hereunder may only be exercised by the Grantee (except that, in the event of his Disability, the Option
may be exercised by his or her legal guardian or legal representative) during the Grantees lifetime and, in the event of the Grantees death, the Option shall be exercisable (subject to the limitations specified in the Plan) solely by the
executor or administrator of the deceased Grantees estate or the Person(s) to whom the deceased Grantees rights under the Option shall pass by will or the laws of descent and distribution, to the extent that the Option is exercisable
pursuant to this Agreement.

4.2 Procedure for Exercise.

(a) The Option may be exercised in whole or in part with respect to any portion that is exercisable. To exercise any portion of the Option
granted hereunder, the Grantee (or such other Person who shall be permitted to exercise the Option as set forth in Section 4.1) must complete, sign and deliver to the Company (to the attention of the Companys Secretary) a notice of
exercise substantially in the form attached hereto as Exhibit A (or in such other form as the Committee may from time to time adopt and provide to the Grantee) (the Exercise Notice), together with (i) payment in full of the
Exercise Price multiplied by the number of Units with respect to which the Option is exercised, (ii) any required agreements described in the Plan, and (iii) the Option to which the Option Units relate. The Grantees right to exercise
the Option shall be subject to the satisfaction of all conditions set forth in the Exercise Notice. Payment of the Exercise Price shall be made in cash (including check, bank draft or money order) or, if subsequent to an Initial Public Offering, to
the extent permitted by the Committee, (i) through the delivery of irrevocable instructions to a broker to sell shares of common stock of the successor corporation obtained upon the exercise of the Option and to deliver promptly to the Company
an amount out of the proceeds of such Sale equal to the aggregate Exercise Price for the shares being purchased, or (ii) in shares of common stock of the successor corporation that have been held for such period of time as may be required by
the Committee in order to avoid adverse accounting treatment to the Company, the successor corporation, or their affiliates. The Fair Market Value of shares of common stock of the successor corporation delivered on exercise of the Option shall be
determined as of the date of exercise. Any fractional shares will be paid in cash.

(b) The obligation of the Company to
deliver Units upon exercise of the Option shall be subject to all applicable laws, rules, and regulations and such approvals by governmental agencies as may be deemed appropriate by the Board or the Board, including such actions as Company counsel
shall deem necessary or appropriate to comply with relevant securities laws and regulations. The Company may require that the Grantee (or other person exercising the Option after the Grantees death) represent that the Grantee is purchasing
Units for the Grantees own account and not with a view to or for sale in connection with any distribution of the Shares, or such other representation as the Board deems appropriate.



---

4.3 Required Agreements. Prior to an Initial Public Offering, no election to exercise any portion
of the Option granted hereunder shall become effective unless and until the Grantee executes a counterpart of the Companys Agreement of Limited Partnership in order to become bound thereby.

4.4 Conditional Exercise in Contemplation of an Acceleration Event. In contemplation of an Acceleration Event, the Grantee may conditionally
exercise, at least 15 days prior to such event, the portion of his or her Option that is exercisable. Such conditional exercise shall become null and void if the anticipated Acceleration Event does not occur within 6 months following the date of
such conditional exercise. A conditional exercise shall become binding upon the Grantee (and such Grantee shall become obligated to pay the Exercise Price therefore) upon the occurrence of the Acceleration Event.

4.5 Withholding of Taxes. All obligations of the Company under this Agreement shall be subject to the rights of the Company, as set forth in the
Plan, to withhold amounts required to be withheld for any applicable taxes with respect to any Option Units issuable under the Plan, and the Company may defer such issuance unless indemnified to its satisfaction. Subject to Board approval, the
Grantee may elect to satisfy any tax withholding obligation of the Company with respect to the Option by having Shares withheld up to an amount that does not exceed the minimum applicable withholding tax rate for federal (including FICA), state and
local tax liabilities.

4.6 Repurchase Right. The provisions of this
Section 4.6 shall cease to apply subsequent to the later of (i) 100 days following an Initial Public Offering, or (ii) the 5thanniversary of the date of this Agreement.

(a) On or after the date the Grantee exercises all or a portion of the Option
granted hereunder, the Company shall have the right and option to purchase for a period of 90 days from the date of the Grantees termination of service for any reason (or, if later, for a period of 300 days from the last date the Grantee
exercised the Option), and if the Company exercises such right, each Grantee shall be required to sell to the Company, any or all of his Option Units at a price per Unit equal to the Fair Market Value (as of the date the Company exercises such
right); provided, however, that in the event of a Grantees termination of employment (other than as a result of death or Disability) (i) by the Company for Cause, or (ii) by the Grantee without Good Reason, then the purchase price
per Unit shall be the lesser of (A) Cost or (B) Fair Market Value.

(b) The Company shall, after a Grantees
employment has terminated for any reason, have the right and option to purchase and if the Company exercises such right each Grantee shall be required to sell to the Company, any or all of his or her then outstanding Options at a price per Unit
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; provided, however, that in the event of a Grantees termination of employment
(other than as a result of death or Disability) (A) by the Company for Cause, or (B) by the Grantee without Good Reason, then the Option shall immediately terminate upon the termination of employment (as provided in Section 5.2
below).

(c) If the Company desires to exercise its right to purchase
any Options or Option Units pursuant to this Section 4.6, the Company shall, not later than 60 days after the date of the Grantees termination of employment (or, with respect to Section 4.6(a), if later, 300 days from the last date
an Option, or a portion of an Option, was exercised), send written notice of its intention to purchase such Units. The closing of the purchase shall take place at the principal office of the Company on the 30thday after the giving of notice by the Company of its exercise of its option to purchase.

(d) The Company shall have the right to assign any or all of its rights to purchase the Option Units pursuant to this Section 4.6;
provided, however, that the assignee of such rights may purchase the Option Units only by delivery of a cashiers check or a certified check.

4.7 Payment for Units. If at any time the Company elects to purchase any Option Units pursuant to Section 4.6 hereof, the Company shall pay the purchase price for such Option 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. If the Company will pay any portion of the purchase price for Option Units with a Junior Subordinated Note, the Company shall give the
Grantee notice of the amount of such note (which may not exceed 55% of the Spread) at least 20 days prior to such purchase.

Article V.

5.1 Expiration Date. The Option shall expire at 5:00 p.m. Eastern Standard Time on the day prior to the tenth anniversary of the date of this Agreement (the Expiration Date), subject to Section 5.2 below.

pursuant to this Agreement.
