RELEASE 8:00 AM –December 17, 2013

HUDSON CITY BANCORP, INC. AND M&T BANK CORPORATION ANNOUNCE FURTHER

EXTENSION OF TIME TO COMPLETE PROPOSED MERGER

HUDSON CITY CONTINUES WITH STRATEGIC INITIATIVES

Paramus, New Jersey, December 17, 2013 - Hudson City Bancorp, Inc. (NASDAQ: HCBK) (“Hudson City”) and M&T Bank Corporation (“M&T”) announced today that additional time will be required to obtain a regulatory determination on the applications necessary to complete their proposed merger. As a result, M&T and Hudson City have agreed to extend the time to complete the merger until December 31, 2014 pursuant to Amendment No. 2 to the Agreement and Plan of Merger. The consideration and exchange ratio as provided in the Merger Agreement will remain the same.

In early 2013, M&T learned that the Federal Reserve identified certain regulatory concerns with M&T’s procedures, systems and processes relating to M&T’s Bank Secrecy Act and anti-money-laundering compliance program and commenced a major initiative intended to fully address the Federal Reserve’s concerns, which is ongoing. In April 2013, M&T and Hudson City entered into their first extension of the Merger Agreement.

In order for Hudson City to pursue its Strategic Plan initiatives during the pendency of the merger the parties agreed to amend the Merger Agreement to permit Hudson City to take action under its Strategic Plan. M&T has received no assurance from the Federal Reserve as to whether or when the Federal Reserve will approve the merger. However, M&T and Hudson City believe that the earliest time the merger could be completed is in the latter half of 2014.

Mr. Ronald E. Hermance, Jr., Chairman and Chief Executive Officer of Hudson City, stated “While all parties are disappointed that the transaction is delayed further we are gratified that M&T continues to see the value in the Hudson City franchise. Our Board of Directors continues to believe that the M&T transaction is ultimately in the best interest of the company and our shareholders, but is also committed to diversifying our business model by continuing to pursue our Strategic Plan.”

Prior to the announcement of the merger, Hudson City retained an outside consultant to assist management in developing a strategic plan. The operational core of the Strategic Plan is the expansion of our loan and deposit product offerings over time to create more balanced sources of revenue and funding. We believe that the markets in which we operate provide significant opportunities for the Hudson City brand to capture market share in products and services that we have not actively pursued previously. The Strategic Plan includes initiatives such as secondary mortgage market operations, commercial real estate

lending, the introduction of small business banking products and developing a more robust suite of consumer banking products. When we announced in April that additional time would be required to obtain regulatory approval, we charted a dual path for Hudson City. We continued to plan for the completion of the merger, but we also refreshed the Strategic Plan, prioritizing the matters that we could achieve during the pendency of the merger, such as our secondary mortgage market operations and commercial real estate lending initiatives, and proceeded with implementation of those prioritized matters. Given the further delay in closing the transaction, Hudson City and M&T have agreed that Hudson City will be permitted to proceed with its Strategic Plan as noted above. Many of the initiatives require significant lead time for full implementation and roll out to our customers. We expect commencement of the roll out of the prioritized initiatives during 2014.
