Re: Decision Not to Seek Re-election to Board of Directors
Dear Mr. Rupp,
This letter confirms my oral discussion with you on December 11, 2007 during which I informed you of my decision not to stand for re-election
to Olin’s Board of Directors when my term expires on April 24, 2008, due to my heavy commitments in China. Accordingly, I shall resign as a Director
and as a member of the Compensation Committee and Directors and Corporate Governance Committee of Olin Corporation effective on April 24, 2008.
Thank you.
Very truly yours,
/s/ Virginia A. Kamsky
