Re: Resignation From Board
Dear Jerry,
As we have discussed, please accept this letter as my formal resignation from the Board of Directors of Graham Corporation, effective immediately. Although I am electing to resign from Graham’s Board in order to pursue other opportunities, I have enjoyed my tenure on the Board and wish Graham and its directors, officers and employees continued future success.
Best regards,
