Note on Repurchase Program

Under the program, shares may be repurchased periodically in open
market transactions at prevailing market prices in accordance with
federal securities laws. The actual timing, number and value of shares
repurchased under the program will be determined by management at its
discretion and will depend on a number of factors, including the market
price of Trinseo’s ordinary shares, general market and economic
conditions, applicable legal requirements, and other business
considerations. Repurchased shares will become treasury shares and may
be utilized for general corporate purposes, including reissuance
pursuant to Trinseo’s equity-based incentive plan, unless subsequently
retired in whole or in part at a meeting of our shareholders. The
share repurchase program does not obligate the Company to acquire any
particular amount of its ordinary shares, and it may be suspended or
terminated at any time in the Company’s discretion.
