Item 5.02 Departure of Directors or Principal  Officers;  Election of Directors;
Appointment of Certain Officers; Compensatory Arrangements of Certain Officers

On January 22, 2009,  Meridian  Interstate  Bancorp,  Inc. (the "Company"),  the
holding company of East Boston Savings Bank (the "Bank"), announced that Deborah
J. Jackson has been appointed as the new President and Chief  Operating  Officer
of the Company and Bank. Ms. Jackson is expected to commence her duties on March
4, 2009.

Ms.  Jackson,  age 51, has over 25 years of banking  experience  beginning  with
State  Street Bank and  continuing  through to her most  recent  position as the
Chief Financial  Officer for Hingham  Institution for Savings,  a position which
she has held for the past 14 years.

For more information regarding Ms. Jackson's  appointment,  please see the press
release dated January 22, 2009, attached as Exhibit 99.1 to this Current Report.

In  connection  with the  appointment,  the Bank has entered into an  employment
agreement (the "Agreement") with Ms. Jackson.  The Agreement has an initial term
of  twenty-four  (24) months,  subject to daily renewal unless written notice of
non-renewal  is  provided  to the  executive.  Under  the  Agreement,  upon  the
occurrence of either the  executive's  involuntary  termination of employment or
the  executive's  voluntary  termination  of  employment  for "good  reason" (as
defined in the Agreement) (the "Termination of Employment"),  the Company or the
Bank  will pay the  executive  (or in the  event of her  subsequent  death,  her
estate),  a lump sum amount  equal to two (2) times her base salary in effect on
the  date  of  the  Termination  of  Employment.  The  Agreement  also  includes
non-competition and non-solicitation  provisions to which the executive would be
subject for a period of  twenty-four  (24) months  following her  Termination of
Employment.

In connection  with the  appointment,  the Bank also entered into a supplemental
executive  retirement agreement (the "SERP") with Ms. Jackson. The SERP provides
Ms. Jackson with a retirement benefit following the executive's retirement on or
after the completion of fourteen  years of service equal to $1,650,000.  Amounts
under the SERP are payable on the first day of the month  following the lapse of
six (6) months after termination of employment.  The SERP provides for a reduced
benefit  in the event  the  executive  terminates  her  employment  prior to the
completion  of  fourteen  years of  service,  for a reason  other than change in
control.

The  foregoing  description  of the  Agreement  and  SERP are  qualified  in its
entirety by reference  to the  Agreement  and SERP that are  attached  hereto as
Exhibits 10.1 and 10.2 of this Current Report,  and is incorporated by reference
into this Item 5.02.
