March 2, 2016

Dear Fellow Shareholder:

According to our latest records, we have not yet received your vote for the important Special Meeting of Shareholders, which will be held on March 23, 2016, relating to the proposed merger with First Niagara Financial Group. Our Board of Directors unanimously recommends that you vote FOR all proposals. We believe that this is a compelling opportunity for our company and our shareholders. The merger is expected to generate attractive financial returns and create a stronger, more balanced franchise.

Your vote is important. Approval of the merger requires the affirmative vote of the majority of KeyCorp common shares outstanding. Importantly, not voting has the same impact as a vote against the merger.

If you have not already done so, please vote TODAY by telephone, via the Internet, or by signing, dating and returning the enclosed proxy card in the envelope provided, to ensure that your shares are represented at this important meeting.

Thank you for your support.

Sincerely,

 

Beth E. Mooney

Chairman of the Board and Chief Executive Officer
