KRATON PERFORMANCE POLYMERS, INC. RESTRICTED STOCK UNIT AWARD AGREEMENT

Upon acceptance by you through the online acceptance procedures set forth at www.benefitaccess.com, this Restricted Stock Unit Award Agreement (this “Agreement”) is made effective as of the Grant Date (defined below) between Kraton Performance Polymers, Inc. (the “Company”) and you (the “Participant”). This Agreement evidences a grant of restricted stock units consisting of an unfunded and unsecured promise to deliver shares of the common stock, $0.01 par value, of the Company (“Common Stock”) under the Company’s 2009 Equity Incentive Plan (as amended, the “Plan”). Unless otherwise indicated, any capitalized term used but not defined herein shall have the meaning ascribed to such term in the Plan.

1.Grant of Restricted Stock Units. Pursuant to, and subject to, the terms and conditions set forth herein and in the Plan, the Company hereby grants to the Participant an award of the number of restricted stock units of the Company set forth on the Participant’s online award acceptance page at www.benefitaccess.com, which is incorporated by reference herein (collectively, the “Restricted Stock Units”). Each Restricted Stock Unit constitutes an unfunded and unsecured promise of the Company to deliver one share of Common Stock to Participant on the vesting date subject to the terms and conditions of this Agreement. Participant’s rights with respect to the Restricted Stock Units shall be forfeitable until the Restricted Stock Units vest in accordance with Section 4. As a holder of Restricted Stock Units, the Participant has the rights of a general unsecured creditor of the Company unless and until the Restricted Stock Units are converted to shares of Common Stock upon vesting and transferred to Participant, as set forth herein. During the period prior to vesting of the Restricted Stock Units in accordance with Section 4, the Restricted Stock Units shall be bookkeeping entries only, and Participant shall have no rights to receive any shares of Common Stock hereunder. Participant shall have no voting or other rights of a stockholder of the Company with respect to the Restricted Stock Units prior to the issuance of Shares in accordance with Section 6.

2.Grant Date. The grant date of the Restricted Stock Units (the “Grant Date”) is the date set forth on the Participant’s online award acceptance page at www.benefitaccess.com, which is incorporated by reference herein.

3.Incorporation of Plan. All terms, conditions and restrictions of the Plan are incorporated herein and made part hereof as if stated herein. If there is any conflict between the terms and conditions of the Plan and this Agreement, the terms and conditions of the Plan, as interpreted by the Committee, shall govern. All capitalized terms used herein that are not defined in this Agreement shall have the meanings given to such terms in the Plan.

4.Vesting Date; Settlement. The Restricted Stock Units shall become vested as follows: 100% of the Restricted Stock Units shall vest on (i) the third anniversary of the Grant Date; provided that the Participant remains continuously employed by the Company through such date; or (ii) the date of the Participant’s employment is terminated due to Disability or death. Notwithstanding the foregoing, if within the one-year period following a Change in Control the Participant’s employment is terminated by the Company or its affiliate without Cause, all Restricted Stock Units held by such Participant shall immediately vest as of the effective date of such termination of the Participant’s employment subject to the Participant's execution of an effective general release and waiver of all claims against the Company, its affiliates and their respective officers and directors related to the Participant’s employment, in a form acceptable to the Company at the Participant’s termination of employment. Upon the occurrence of the date of vesting described above, the Company shall deliver to the Participant the applicable number shares of Common Stock via electronic book-entry issuance. If and when cash dividends or other cash distributions are paid or distributed with respect to the Common Stock while the Restricted Stock Units are outstanding, the dollar amount of such dividends or distributions with respect to the number of shares of Common Stock then underlying the Restricted Stock Units shall be reflected in a notional account maintained by the Company on your behalf. Any such cash dividends or other cash distributions shall vest and be paid in cash if and at such times as the underlying Restricted Stock Units are vested and paid.

For purposes of this Agreement, “Disability” has the meaning ascribed to it in the Company’s long-term disability plan, and “Cause” means (i) a material breach by the Participant of any of the Participant’s obligations under

any written agreement with the Company or any of its affiliates, (ii) a material violation by the Participant of any of the Company’s policies, procedures, rules and regulations applicable to employees generally or to employees at your grade level, in each case, as they may be amended from time to time in the Company’s sole discretion; (iii) the failure by the Participant to reasonably and substantially perform his or her duties to the Company or its affiliates (other than as a result of physical or mental illness or injury); (iv) the Participant’s willful misconduct or gross negligence that has caused or is reasonably expected to result in material injury to the business, reputation or prospects of the Company or any of its affiliates; (v) the Participant’s fraud or misappropriation of funds; or (vi) the commission by the Participant of a felony or other serious crime involving moral turpitude; provided that if the Participant is a party to an employment agreement with the Company or its affiliate (an “Employment Agreement”) at the time of his or her termination of employment and such Employment Agreement contains a different definition of “cause” (or any derivation thereof), the definition in such Employment Agreement will control for purposes of this Agreement.

If a Participant is terminated without Cause and, within the twelve (12)-month period subsequent to such termination of employment, the Company determines in good faith that the Participant’s employment could have been terminated for Cause, subject to anything to the contrary that may be contained in the Participant’s Employment Agreement at the time of his or her termination of employment, the Participant’s employment will, at the election of the Company, be deemed to have been terminated for Cause, effective as of the date the events giving rise to Cause occurred.

5.Forfeiture; Restrictions. Subject to the provisions of the Plan and Section 4 of this Agreement, with respect to the Restricted Stock Units that have not become vested on the date the Participant’s employment is terminated, the award of Restricted Stock Units shall expire and such unvested Restricted Stock Units shall immediately be forfeited on such date. Participant shall not sell, transfer, pledge, assign, alienate, hypothecate, or otherwise encumber or dispose of the Restricted Stock Units other than by will or the laws of descent and distribution.

6.Delivery of Shares; Compliance with Securities Laws. Upon the vesting of any Restricted Stock Units granted hereunder, the Company shall direct its transfer agent to record by electronic book-entry in Participant’s name a number of unrestricted shares of Common Stock equal to the whole number of Restricted Stock Units that become vested hereunder. Nothing herein shall obligate the Company to register the Restricted Stock Units pursuant to any applicable securities law or to take any other affirmative action in order to cause the issuance or transfer of the Restricted Stock Units to comply with any law or regulation of any governmental authority. The Company shall not be required to issue any shares of Common Stock prior to: (a) the obtaining of any approval from any governmental agency which the Company determines to be necessary or advisable; and (b) the Participant’s payment to the Company of any federal, state or local tax or other withholding owed by Participant as a result of vesting of the Restricted Stock Units.

7.Delays or Omissions. No delay or omission to exercise any right, power, or remedy accruing to any party hereto upon any breach or default of any party under this Agreement, shall impair any such right, power or remedy of such party nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of or in any similar breach or default thereafter occurring, nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part of any party of any breach or default under this Agreement, or any waiver on the part of any party or any provisions or conditions of this Agreement, shall be in writing and shall be effective only to the extent specifically set forth in such writing.

There are no restrictions, agreements, promises, representations, warranties, covenants or undertakings with respect to the subject matter hereof other than those expressly set forth herein and the Plan. This Agreement and the Plan supersede all prior agreements and understandings between the parties with respect to the subject matter of this Agreement.
