Item 5.           Other Events


                  Effective June 23, 2003, the Registrant's  banking subsidiary,
           Enterprise  Bank and Trust Company  ("EBTC"),  along with EBTC's real
           estate  investment trust  subsidiary,  Enterprise  Realty Trust, Inc.
           ("ERT"),  has entered into a settlement  agreement  (the  "Settlement
           Agreement") with the Commissioner of the Massachusetts  Department of
           Revenue.  The  Settlement  Agreement  sets  forth  the  terms  of the
           settlement of the dispute  between EBTC and the Department of Revenue
           (the "DOR")  regarding the taxation of income earned by a bank's real
           estate  investment trust subsidiary and paid as dividends to the bank
           under applicable  Massachusetts  tax law.  Further details  regarding
           this  dispute  are  contained  in Item 7 of the  Registrant's  Annual
           Report on Form 10-K for the year ended  December  31,  2002 under the
           heading "Massachusetts Department of Revenue Tax Dispute".

                  EBTC was one of approximately 60 banking institutions involved
            in this  dispute  with the DOR.  The  substantial  majority of these
            institutions   have  also   settled  with  the  DOR.  All  of  these
            settlements are on the same terms as the settlement reached with the
            DOR by EBTC. Pursuant to the terms of the Settlement Agreement, EBTC
            paid to the Commonwealth of Massachusetts on June 23, 2003 an amount
            equal to 50% of the additional tax that the DOR had assessed against
            EBTC for the tax years ended  December 31, 1999,  2000 and 2001 plus
            applicable interest accrued through the date of such payment.  Under
            the Settlement Agreement, EBTC also agreed to pay an amount equal to
            50% of the additional tax that the DOR sought to impose with respect
            to  EBTC's  tax  year  ended  December  31,  2002.  Further  details
            regarding  the  amounts  of the  additional  taxes  that the DOR had
            sought to impose for these prior tax years is also contained in that
            section of the  Registrant's  Annual Report on Form 10-K referred to
            in the last sentence of the preceding paragraph.

                Exhibit 99        Letter to stockholders dated June 30, 2003


Item 9.     Regulation FD Disclosure


                  The Registrant  previously recorded in its first quarter ended
            March 31,  2003 a  one-time  income tax  expense of $1.9  million to
            account  for the  maximum  additional  income  tax  expense,  net of
            federal  income tax benefit and deferred tax asset,  that EBTC could
            have  incurred in  connection  with its  dispute  with the DOR. As a
            result of the terms of the Settlement Agreement,  as described above
            in Item 5 of this report,  the  one-time  income tax expense to EBTC
            with respect to its tax years ended  December 31, 1999,  2000,  2001
            and 2002 will be approximately $1.075 million, net of federal income
            tax benefit and deferred tax asset, which is $825,000 less than EBTC
            previously reserved for. Consequently,  the Registrant will record a
            one-time  credit to earnings for its second  quarter ending June 30,
            2003 in the amount of $825,000.

                  As  a  result  of  this  one-time  credit  to  earnings,   the
            Registrant has provided revised guidance as to its expected earnings
            for the year ending  December  31, 2003.  This revised  guidance was
            contained in a letter to the  Registrant's  stockholders,  which was
            first  mailed on or about June 30,  2003.  A copy of this  letter is
            included as Exhibit 99 to this report.
