Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Included in this amount are the following amounts previously reported on Form 4 as separate line items: 1,000 shares previously reported as attributable to Restricted Stock Account I, 7,100 shares previously reported as attributable to Restricted Stock Account 2007-2009 LTIP, 44,758 shares previously reported as attributable to Restricted Stock Account I (Time Based Shares), and 45,000 shares previously reported as attributable to Restricted Stock Account 2008-2010 LTIP. Certain amounts attributable to the foregoing Restricted Stock Accounts are subject to vesting requirements and thus may not be distributed. In order to provide consistency in reporting, the Reporting Person is voluntarily reporting the entire amount of the grants attributable to the LTIP on Table I even though the Reporting Person may be required to report on Table I only those amounts which have vested pursuant to the terms of the grant.
(2) These shares are being withheld to satisfy tax obligations relating to the vesting of shares previously reported as being attributable to Restricted Stock Account I. The shares which are not subject to withholding are included in the amount of shares listed in Column 5 of this line item.
(3) The Reporting Person has acquired 3,248 shares of common stock under the Chemtura Corporation Employee Stock Purchase Plan since January 1, 2008. The information in this report is based on a plan statement dated as of December 31, 2008.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
