Exhibit 10.11

RETIREMENT AGREEMENT

This RETIREMENT AGREEMENT (the “Agreement”) is made as of the 23rd day of
December, 2010, by and between Brookline Bancorp, Inc., a Delaware corporation
(the “Company”) and Brookline Bank, a United States-chartered stock savings bank
(the “Bank”) and Charles H. Peck (the “Executive”).

WHEREAS, the Company and the Bank recognize the Executive’s comprehensive
knowledge of the business of the Company and the Bank and, as such, wishes to
establish the terms of the Executive’s continued relationship with the Company
and the Bank after the end of his employment; and

WHEREAS, the Board of Directors of the Company (the “Board”) and the Board of
Directors of the Bank (the “Bank Board”) have determined that it is in the best
interest of the Company and the Bank to assure that the Executive enters into
this Agreement;

NOW, THEREFORE, in consideration of the mutual promises and conditions set forth
in this Agreement, the sufficiency of which is hereby acknowledged, the Company,
the Bank and the Executive agree as follows:

1.      Retirement.  Effective as of December 23, 2010 (the “Retirement Date”),
the Executive will retire as an employee of the Company and the Bank and will
resign from any and all other positions that he may hold with the Bank
(including those with any or all of the Bank’s affiliates), except as (a) a
member of the Board and the Bank Board, (b) a member of the Executive Committee
of the Board and the Bank Board and (c) a member of the Management Loan
Committee of the Board and the Bank Board.  The Executive, the Company and the
Bank agree that, as of the Retirement Date, all salary, bonus, and any other
employee compensation otherwise payable to the Executive will cease, and any
benefits the Executive has or might have under any Bank-provided employee
benefit plans, programs, or practices (including, but not limited to
participation in group medical, dental and vision plans; short-term and
long-term disability insurance; basic and executive life insurance; basic
accidental death and dismemberment insurance; and participation in the employee
assistance plan) will terminate, except as required by federal or state law, by
the terms of the respective benefit plan, or as otherwise described in this
Agreement.  Notwithstanding anything in this Section to the contrary, nothing
herein shall terminate (x) the Executive’s vested rights to receive retirement
benefits provided by the Bank’s qualified and nonqualified retirement plans, (y)
the Executive’s rights with respect to vested options to purchase common stock
of the Company and other equity awards granted to the Executive that are
outstanding as of the Retirement Date, pursuant to and subject to the terms of
any and all applicable stock option plans and agreements, including any such
terms and conditions with respect to any post-retirement exercise periods, or
(z) the Executive’s right to any reimbursement for any outstanding, reasonable
business expenses incurred by the Executive on the Company’s or the Bank’s
behalf prior to the Retirement Date, after the Company’s or the Bank’s (as
applicable) timely receipt of appropriate documentation pursuant to the
applicable business expense reimbursement policy.

2.      Transfer of Bank-Owned Automobile.  On or about the Retirement Date, the
Bank  shall transfer to the Executive a 2004 Volvo S-8, currently owned by the
Bank, at no cost, other than any necessary local taxes and registration fees.

--------------------------------------------------------------------------------

3.      Board Membership.  The Executive will remain on the Board and the Bank
Board after the Retirement Date and will be entitled to all regular board fees
payable to members of the Board (currently, such fees are approximately $53,000
per year).  The Executive will also remain (a) a member of the Executive
Committee of the Board and the Bank Board and (b) a member of the Management
Loan Committee of the Board and the Bank Board.  The Executive shall devote
approximately 12 hours per week to the performance of such Board and Bank Board
duties and responsibilities.

4.      Restricted Stock Grant.  In consideration of the Executive’s agreements
and covenants hereunder, on October 6, 2010, pursuant to a separate award
agreement, the Company granted the Executive an award of 6,000 restricted shares
of the Company’s common stock (the “Restricted Stock Grant”) under the Brookline
Bancorp, Inc. 2003 Stock Option Plan (the “Plan”).  The Restricted Stock Grant
is subject to the terms and conditions of the Plan and such award agreement, and
shall vest with respect to 100 percent of such shares of restricted stock
on  the second anniversary of the grant date, provided that (a) this Agreement
becomes effective pursuant to Section 10, below, and (b) the Executive continues
to provide services as a member of the Board on such vesting date.

5.      Consulting Services.

         (a)      For the one-year period beginning on the day following the
Retirement Date (the “Consulting Period”), the Executive shall be available to
consult with the Chief Executive Officer and other designated senior officers of
the Bank and the Company as requested by such officers from time to time (the
“Consulting Services”).  Such Consulting Services shall include assisting the
Company and the Bank in maintaining their core relationships and assisting the
Company and the Bank with their business development efforts.  It is anticipated
that the Executive shall devote approximately four hours per week to the
performance of the Consulting Services.  In consideration for such Consulting
Services, the Company will provide the Executive with a monthly consulting fee
of $4,000, payable on the last day of each month during the Consulting Period.

         (b)      As a consultant, the Executive’s status is that of an
independent contractor, and the Executive shall be responsible for all taxes,
including self-employment taxes.  As a consultant, the Executive shall have no
authority to bind the Company or the Bank to any agreement or obligation of any
type or nature.  Further, as a consultant, the Executive shall not accrue any
benefits under, or in any way be covered by, benefit plans of the Company or the
Bank or any of their affiliates, subsidiaries or related entities (except to the
extent Executive is eligible for and elects to receive continuation coverage
under COBRA and/or to the extent the Executive would be eligible for such
benefits under the terms of such plans following his retirement) following the
Retirement Date.

         (c)      The parties anticipate that the Executive would be expected to
perform the Consulting Services at a level that shall not exceed 20 percent of
the average level of bona fide services performed by the Executive for the
Company and/or the Bank during the 36-month period prior to the Retirement
Date.  Therefore, the parties agree that the Executive would incur a “Separation
from Service” (within the meaning of Section 409A of the Internal Revenue Code
of 1986, as amended and the regulations thereunder) on the Retirement
Date.  Accordingly, the Executive would be entitled to commence to receive the
retirement benefits provided (a) under the Supplemental Retirement Income
Agreement, dated as of February 28, 1995, as amended, between the Bank and the
Executive (the “SERP”) upon and in connection with such Separation from Service
in accordance with the terms of the SERP and the Executive’s elections
thereunder and (b) under the 2005 Supplemental Retirement Income Agreement,
dated as of January 1, 2005 between the Bank and the Executive (the “2005 SERP”)
in a lump-sum on the first day of the month following the six month anniversary
of such Separation from Service in accordance with the terms of the 2005
SERP.  The Executive acknowledges and agrees that he is not entitled to any
payments or benefits in connection with his retirement under the Employment
Agreement, dated as of February 25, 1998, as amended, between the Bank and the
Executive.

--------------------------------------------------------------------------------

         (d)      In consideration of the fees provided herein, the Executive
agrees to comply with the non-competition and non-solicitation provisions of
Section 8 of the SERP and Section 9 of the 2005 SERP during the Consulting
Period.  The Executive agrees that it would be difficult to measure any harm
caused to the Company and the Bank that might result from any breach by the
Executive of his promises set forth in this Section 5(d) and that in any event
money damages would be inadequate remedy for any such breach.  Accordingly, if
the Executive breaches, or proposes to breach, any portion of his obligations
under this Section 5(d), the Company and/or the Bank shall be entitled, in
addition to all other remedies it or they may have, to an injunction or other
appropriate equitable relief to restrain any such breach, without showing or
proving any actual damage to the Company and/or the Bank and without the
necessity of posting a bond.

         (e)      The Company and the Bank shall be the exclusive owner of all
work product developed by the Executive in connection with or as a result of the
Executive’s performance of Consulting Services.  The Executive shall maintain
the confidentiality of (x) any work product develop by the Executive in the
course of performing the Consulting Services and (y) all confidential or
proprietary information of the Company, the Bank or any of their affiliates that
is shared with the Executive in connection with the performance of Consulting
Services.

         (f)      The Consulting Period shall terminate immediately upon the
death of Executive.  The parties hereto may terminate the Consulting Period and
the Consulting Services at any time, and for any reason or for no reason, upon
30 days prior written notice to the other party.  If the Company and the Bank
terminate the Consulting Period pursuant to the previous sentence, the Company
and the Bank may, in their sole discretion, immediately terminate the Consulting
Period and Consulting Services and pay to the Executive the compensation the
Executive would have otherwise received during such 30 day period in lieu of the
Executive providing any services during such thirty 30 day period.  The
Company’s and the Bank’s obligation to pay consulting fees shall cease in
connection with such termination (other than with respect to accrued amounts).

         (g)      The parties may agree to extend the Consulting Period for
additional one-year periods upon mutually acceptable terms in connection with
the expiration of the Consulting Period.

6.      Indemnification.  The Executive will continue to receive reimbursements
for reasonable legal fees, to the fullest extent permitted by the
indemnification provisions set forth in the Company’s and Bank’s (as applicable)
by-laws, with regard to legal matters arising during, and on account of, the
Executive’s employment with the Company and the Bank.

7.      General Release of Claims.  The Executive hereby irrevocably and
unconditionally releases, acquits and forever discharges the Company, the Bank,
their affiliated and related entities, and their respective predecessors,
successors and assigns, their respective employee benefit plans and fiduciaries
of such plans, and the current and former officers, directors, shareholders,
employees, attorneys, accountants and agents of each of the foregoing in their
official and personal capacities (collectively referred to as the “Releasees”)
generally from all claims, demands, debts, damages and liabilities of every name
and nature, known or unknown (“Claims”) that, as of the date when the Executive
signs this Agreement, the Executive has, ever had, now claims to have or ever
claimed to have had against any or all of the Releasees.  This release includes,
without limitation, all Claims:  relating to the Executive’s employment by and
termination of employment with the Company and the Bank; of wrongful discharge;
of breach of contract; of retaliation or discrimination under federal, state or
local law of the United States (including, without limitation, Claims of age

Claims of disability discrimination or retaliation under the Americans with
Disabilities Act, and Claims of discrimination or retaliation under Title VII of
the Civil Rights Act of 1964); under any other federal or state statute; of
defamation or other torts; of violation of public policy; for wages, bonuses,
incentive compensation, stock, stock options, vacation pay or any other
compensation or benefits; and for damages or other remedies of any sort,
including, without limitation, compensatory damages, punitive damages,
injunctive relief and attorney’s fees; provided, however, that this release
shall not affect his rights under this Agreement.  The Executive further
acknowledges that the termination of his employment on the Retirement Date in
accordance with this Agreement will not give rise to any Claims.  As a material
inducement to the Company and the Bank to enter into this Agreement, the
Executive represents that he has not assigned to any third party and has not
filed with any agency or court any Claim released by this Agreement.

--------------------------------------------------------------------------------

8.      Legal Representation.  This Agreement is a legally binding document and

the right to revoke this Agreement by written notice to the Company and the
Bank.  For such a revocation to be effective, it must be delivered so that it is

seven-day revocation period.  This Agreement shall not become effective or

on the first business day following the expiration of the revocation period.

the Executive’s covenants and agreements set forth in Section 8 of the SERP and
Section 9 of the 2005 SERP shall survive the Retirement Date and remain in full
force and effect.

11.      Amendment.  This Agreement shall be binding upon the parties and may
not be abandoned, supplemented, changed or modified in any manner, orally or
otherwise, except by an instrument in writing of concurrent or subsequent date
signed by a duly authorized representative of the parties.  

12.      Validity.  Should any provision of this Agreement be declared or be
determined by any court of competent jurisdiction to be illegal or invalid, the
validity of the remaining parts, terms, or provisions shall not be affected and
said illegal and invalid part, term or provision shall be deemed not to be a
part of this Agreement.

13.      Waiver.  No delay or omission by the Company or the Bank in exercising
any right under this Agreement will operate as a waiver of that or any other
right.  A waiver or consent given by the Company and the Bank on any one
occasion is effective only in that instance and will not be construed as a bar
to or waiver of any right on any other occasion.

14.      Entire Agreement.  This Agreement supersedes all prior agreements,
written or oral, between the Executive and the Bank relating to the subject
matter of this Agreement.  This Agreement may not be modified, changed or
discharged in whole or in part, except by an agreement in writing signed by the

Bank’s by-laws, which shall remain in full force and effect in accordance with
their terms.
