Number of Phantom Stock Units granted: _________

THIS PHANTOM STOCK UNIT AWARD AGREEMENT (this “Agreement”), dated as of the Grant Date specified above, is entered into by and between Solutia Inc., a company organized in the State of Delaware (the “Company”), and the Participant (the “Participant”).

The Phantom Stock Units are granted to the Participant on a stand-alone basis, outside of the Solutia Inc. 2007 Management Long-Term Incentive Plan, as in effect and as amended from time to time (the “Plan”). Notwithstanding the foregoing, it is intended that all of the terms and conditions of the Plan that would otherwise have been applicable to the Phantom Stock Units had the Phantom Stock Units been granted as “Restricted Stock Units” under the Plan (except as otherwise expressly provided herein) be applicable to the Phantom Stock Units, and accordingly, references to the Plan are made herein for such purpose and those terms are incorporated herein by reference. In addition, the Phantom Stock Units shall not be considered “Restricted Stock Units” for purposes of the terms and provisions of the Merger Agreement dated January 26, 2012, by and among the Company, Eastman Chemical Company (“Eastman”) and Eagle Merger Sub Corporation (the “Merger Agreement”, and the consummation of the transactions contemplated by the Merger Agreement, the “Merger”). The Plan is attached as Exhibit 10.8 to the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on February 25, 2011.

NOW, THEREFORE, in consideration of the mutual covenants and promises hereinafter set forth and for other good and valuable consideration, the parties hereto hereby mutually covenant and agree as follows:

1. Incorporation By Reference; Plan Document Receipt. This Agreement is subject to the terms and provisions of the Plan (as in effect on the Grant Date specified above), all of which terms and provisions are made a part of and incorporated in this Agreement as if they were expressly set forth herein. Any capitalized term not defined in this Agreement shall have the same meaning as is ascribed thereto in the Plan. The Participant hereby acknowledges receipt of a true copy of the Plan and that the Participant has read the Plan carefully and fully understands its content. In the event of a conflict between the terms of this Agreement and the terms of the Plan, the terms of the Plan shall control, except as otherwise provided in this Agreement.

2. Grant of Phantom Stock Units Award. The Company hereby grants to the Participant, as of the Grant Date specified above, the number Phantom Stock Units identified above. Except as otherwise provided by Section 11.12 of the Plan, the Participant agrees and understands that nothing contained in this Agreement provides, or is intended to provide, the Participant with any protection against potential future dilution of the Participant’s stockholder interest in the Company for any reason. The Participant shall not have the rights of a stockholder in respect of any Share or Eastman Share (as defined below), as applicable, underlying this Award until such share is delivered to the Participant in accordance with Section 4, as applicable.

3. Vesting.

3.1 Except as otherwise provided in this Section 3, the Phantom Stock Units subject to this grant shall become unrestricted and vested pro rata on each of the first four anniversaries of the Grant Date, provided the Participant is then employed by the Company and/or one of its Subsidiaries or Affiliates.

3.2 Except as otherwise provided in this Section 3, if the Participant’s employment with the Company and/or its Subsidiaries or Affiliates terminates for any reason prior to the vesting of all or any portion of the Phantom Stock Units awarded under this Agreement, such unvested Phantom Stock Units shall immediately be cancelled and the Participant (and the Participant’s estate, designated beneficiary or other legal representative) shall forfeit any rights or interests in and with respect to any such unvested Phantom Stock Units.

3.3 If the Participant’s employment with the Company and/or its Subsidiaries or Affiliates terminates due to the Participant’s Disability, any unvested Phantom Stock Units subject to this grant shall become unrestricted and vested in full immediately upon the Participant’s termination date. For purposes of this Agreement, “Disability,” if the Participant is a party to an employment agreement, shall have the same meaning as in such employment agreement, otherwise, “Disability” shall mean any physical or mental disability which is determined to be total and permanent by a doctor selected in good faith by the Company or the relevant Subsidiary or Affiliate.

3.4 If the Participant’s employment with the Company and/or its Subsidiaries or Affiliates terminates due to the Participant’s death, any unvested Phantom Stock Units shall become vested as of the date of any such termination.

3.5 If, prior to the occurrence of a Change in Control, the Participant’s employment is terminated by the Company and/or its Subsidiaries or Affiliates, the Phantom Stock Units will become vested on a pro rata basis as defined herein if and only if the Participant is a Severance Eligible Participant; i.e., if the Participant is eligible for severance from the Company under the terms of: (a) the Participant’s employment agreement (if any); or (b) the terms of an applicable Company separation pay plan in force at the time of the Participant’s termination. The Phantom Stock Units of Severance Eligible Participants shall vest as follows:

3.5.1

A pro rata amount of any unvested Phantom Stock Units as described in Section 3.1 above shall vest in a percentage equal to: the number of full months in which the Participant was employed from the Grant Date to the Participant’s termination date, plus the number of full months in the Participant’s severance period (i.e., the number of months’ salary which constitute the Participant’s severance payments), divided by the number of full months between the Grant Date and the scheduled vesting date. The pro rata portion of the Phantom Stock Units shall vest immediately upon the Participant’s termination date.

3.6 If the Participant’s employment is terminated by the Company and/or its Subsidiaries or Affiliates for any reason other than “Cause” or if the Participant terminates employment with Company and/or its Subsidiaries or Affiliates for “Good Reason” (as such terms are defined herein), in each case at any time following the occurrence of a Change in Control, the Phantom Stock Units will become vested on a pro rata basis as defined herein.

3.6.1

A pro rata amount of any unvested Phantom Stock Units as described in this Section 3.6 shall vest in a percentage equal to: the number of days in which the Participant was employed during the 2012 calendar year divided by 365. The pro rata portion of the Phantom Stock Units shall vest immediately upon the Participant’s termination date. For the sake of clarity, if the Participant’s employment is terminated pursuant to this Section 3.6 following the 2012 calendar year, any unvested Phantom Stock Units subject to this grant shall become unrestricted and vested in full immediately upon the Participant’s termination date.

3.7 For purposes of this Agreement, “Cause” and “Good Reason”, if the Participant is a party to an employment agreement or a Company severance plan as in effect on the Grant Date, shall have the same meaning as in such (i) employment agreement, or, if none, (ii) the separation pay plan as in effect on the Grant Date, otherwise, “Cause” and “Good Reason” shall be defined herein.

3.7.1

For purposes of this Agreement, “Cause” shall be defined as (i) the continued failure to perform the Participant’s duties to the Company consistent with Participant’s position after written notice from the Company, (ii) a conviction of a felony, or (iii) the Participant’s performance of any material act of theft, embezzlement, fraud or dishonesty. No such determination of Cause shall be made until the Participant has been given written notice detailing the specific Cause event and a period of 30 days following receipt of such notice to cure such event (if susceptible to cure) to the satisfaction of the Company.

3.7.2

For purposes of this Agreement, “Good Reason” shall be defined as: (i) a change of 50 miles or more in the location at which the Participant performs services, (ii) the assignment to the Participant of any duties materially inconsistent with the Participant's position at the time of the Change in Control or any other action by the Company which results in a material diminution in such position, authority, duties or responsibilities (excluding for this purpose an isolated, insubstantial and inadvertent action not taken in bad faith and which is remedied by the Company promptly after receipt of notice thereof given by the Participant), or (iii) a material reduction in the Participant’s annual salary (other than a percentage reduction in annual salary which applies uniformly to all Participant level employees). The Participant shall notify the Company in writing if he or she believes Good Reason exists. The Participant shall set forth in reasonable detail why he or she believes Good Reason exists; provided, however, that the Participant must provide the Company with written notice of Good Reason within a period not to exceed 90 days of the initial existence of the condition alleged to give rise to Good Reason, upon the notice of which the Company shall have a period of 30 days during which it may remedy the condition. In order for a termination to be characterized as for Good Reason, the Participant must terminate for Good Reason after the expiration of this 30-day period, provided that such termination is within 180 days following the initial existence of one or more conditions giving rise to Good Reason and further provided that the condition giving rise to Good Reason was not cured by the Company within the 30-day cure period.
