with the Securities and Exchange Commission relating to the proposed offering of
up to 399,249 shares of Webster's common stock, par value $.01 per share, all of
which shares (the  "Shares") may be issued by Webster  pursuant to the Mechanics
Savings Bank 1996 Officer Stock Option Plan and the Mechanics  Savings Bank 1996
Director Stock Option Plan (the "Plans"). The Plans have become plans of Webster
in connection  with Webster's  acquisition of MECH  Financial,  Inc. on June 23,
2000.  This opinion  letter is furnished to you at your request to enable you to
