Meridian  Interstate   Bancorp,   Inc.  (the  "Company")  reports  that  Gregory
Derderian,  Treasurer and Chief Financial Officer of the Company and East Boston
Savings Bank (the "Bank"),  a subsidiary of the Company,  will resign and retire
effective December 31, 2009.

The Company  reports  that Mark L. Abbate has been  appointed  as the new Senior
Vice President,  Treasurer and Chief Financial  Officer of the Company and Bank.
Mr. Abbate is expected to commence his duties on January 4, 2010.

Mr.  Abbate,  age 54,  has 30 years of  significant  experience  in the  banking
business.  Prior to joining  the  Company  and the Bank,  Mr.  Abbate  served as
Executive Vice President and Chief Financial  Officer of Srata Bank in Franklin,
Massachusetts  from 2007 until Strata's  merger into  Middlesex  Savings Bank in
July 2009.

For more information  regarding Mr. Abbate's  appointment,  please see the press
release  dated  December  15,  2009,  attached as Exhibit  99.1 to this  Current
Report.

In  connection  with the  appointment,  the Bank has  entered  into a change  in
control  agreement  (the  "Agreement")  with Mr.  Abbate.  The  Agreement has an
initial term of  twenty-four  (24) months and renews daily unless written notice
of non-renewal is provided to the  executive.  The Agreement  provides that upon
the occurrence of a "change in control" (as defined in the  Agreement)  followed
by the  executive's  involuntary  termination of employment  without "cause" (as
defined in the Agreement) or the executive's voluntary termination of employment
for "good reason" (as defined in the Agreement),  the Bank will pay Mr. Abbate a
lump sum  amount  equal to the sum of two (2)  times  his  base  salary  and the
highest cash  incentive  compensation  earned by the executive in any one of the
three calendar years immediately  preceding the year of termination and the Bank
will provide Mr. Abbate with continued medical and dental insurance coverage for
two (2) years, with the executive paying his share of employee premiums.

The  foregoing  description  of the  Agreement  is  qualified in its entirety by
reference  to the  Agreement  that is  attached  hereto as Exhibit  10.1 of this
