The Employee’s individual performance modifier will be 1.0. The 2008 bonus payout will be $360,194.00, minus lawful deductions.

The Employee will be credited with at least 3 full months of service when determining the prorated bonus payout for 2009. The 2009 bonus payout will be paid to the Employee during the 2010 calendar year but in no event later than March 15, 2010. The prorated 2009 bonus payouts will be based entirely on Company performance over the course of the full 2009 calendar year and will be weighted based on the following percentages: Acetyl Intermediates Division (65%) and Company (35%). The 2009 prorated bonus will be based on Employee individual performance modifier of 1.0.

d. Equity Awards. In addition to the Time Options and Performance Options that previously vested under the Employee’s Nonqualified Stock Option Agreement dated August 31, 2005, under the terms of such agreement the Employee will, on the Separation Date vest in 58,400 unvested Time Options. In addition, as to his remaining 109,500 Performance Options, the Company agrees that the performance targets for such Performance Options for the period ending December 31, 2008, under the terms of the Employee’s Nonqualified Stock Option Agreement dated August 31, 2005, have been achieved. Once vested, all Time Options and Performance Options shall be exercisable by the Employee through March 31, 2010.

Pursuant to the terms of the Employee’s Nonqualified Stock Option Agreement dated July 25, 2007, the 12,000 stock options that vested on January 1, 2009, shall be exercisable by the Employee through March 31, 2010. All remaining unvested stock options issued pursuant to the Employee’s Nonqualified Stock Option Agreement dated July 25, 2007 shall be canceled on the Separation Date with no additional consideration.

The Company agrees that the Tax Equalization Policies in effect during the Employee’s international assignment will continue to be in effect and applicable as to any compensation, awards, benefits or other taxable income provided to the Employee pursuant to the Agreement and General Release hereto.

However, such tax equalization payments shall be made no later than the end of the second taxable year of the Employee beginning after the taxable year of the Employee in which the Employee’s U.S. Federal income tax return is required to be filed (including any extensions) for the year to which the compensation subject to the tax equalization payment relates, or, if later, the second taxable year of the Employee beginning after the latest such taxable year in which the Employee’s foreign tax return or payment is required to be filed or made for the year to which the compensation subject to the tax equalization payment relates; provided, however, that where such payments arise due to an audit, such payments shall be made by the end of the Employee’s taxable year next following the Employee’s taxable year in which the Employee remits the related taxes.

g. Relocation & Repatriation Costs. Employer waives any obligation for the Employee to reimburse the Company for relocation costs paid by the Company.

k. COBRA Reimbursement and Continued Medical Plan Coverage. As part of the Employee’s repatriation to the U.S., the Employee intends to elect coverage for himself, (and coverage for his currently enrolled family members), no later than 3/6/09, in one of the Employer’s self -insured Employer’s medical and dental plan options available for active employees, pursuant to the requirements of the Consolidated Omnibus Reconciliation Act of 1985, as amended (“COBRA”). The Employer shall reimburse the Employee for each monthly COBRA premium paid by the Employee for a period of twelve (12) months following the date of Employee’s separation, or through March 31, 2010, whichever is later.

From 4/1/09 through 6/30/09, and if Employee’s family maintains its primary residence in Shanghai, China, the Employer will reimburse the Employee the cost difference between In- Network and Out-of- Network eligible health care expenses incurred up to the annual out-of- pocket maximum. Such reimbursement shall occur within 30 days of Employer’s receipt of evidence of valid claims uncovered by the Out –of-Network Plans.

Following the expiration of the Employee’s COBRA coverage, the Employee may continue his coverage (and the coverage of those eligible family members who have exhausted their COBRA coverage) under the Employer’s medical plan for active employees until the Employee attains age 65 provided that the Employee pays each required monthly premium no later than the thirtieth (30) day of the calendar month for which such monthly premium is due.
