Stock;

FURTHER RESOLVED, that any specific resolutions that may be required to have been adopted by the Board of Directors of the

Corporation in connection with the actions contemplated by the foregoing resolutions be, and they hereby are, adopted, and the Proper Officers of the Corporation be, and each of them hereby is, authorized to certify as to the adoption of any and all
