reemployment is not provided by law or by contract, then the Participant shall have a Separation from Service on the first date immediately following such six-month period. 
 Whether a Separation from Service has occurred is determined based on whether the facts and circumstances indicate that the Bank and the Participant reasonably anticipated that no further services would
be performed after a certain date or that the level of bona fide services the employee would perform after such date (whether as an employee or as an independent contractor) would permanently decrease to an amount less than 50% of the average level
of bona fide services performed over the immediately preceding 36 months (or such lesser period of time in which the Participant performed services for the Bank). The determination of whether a Participant has had a Separation from Service shall be
made by applying the presumptions set forth in the Treasury Regulations under Code Section 409A.

the first six (6) months following the Participant’s Separation from Service. Rather, any payment which would otherwise be paid to the Participant during such period shall be accumulated and paid to the Participant in a lump sum on the
first day of the seventh month following such Separation from Service. All subsequent payments of the Participant’s SERP Account Balance shall be paid in the manner specified in the Plan. 

6.8 Modification of Time and Form of Payment. In the event a Participant desires to modify the time or form of payment of
his or her SERP Account Balance, the Participant may do so on a written form provided by the Bank, provided that:

must be made at least 12 months before the date of the first scheduled payment.

Plan shall be interpreted to comply with or be exempt from Code Section 409A, and all provisions of the Plan shall be construed in a manner consistent with the requirements for avoiding taxes or penalties under Code Section 409A. Each
payment that is payable pursuant to this Plan is intended to constitute a “separate payment” for purposes of Treasury Regulation Section 1.409A-2(b)(ii).

 ARTICLE X 

MISCELLANEOUS 
 10.1 Unfunded Plan. This Plan is intended to be an unfunded plan maintained primarily to provide deferred compensation benefits for a select group of management or highly compensated
employees. This Plan is not intended to create an investment contract, but to provide tax planning opportunities and retirement benefits to eligible individuals who have elected to participate in the Plan. Participants are select members of
management who, by virtue of their position with the Bank, are uniquely informed as to the Bank’s operations and have the ability to materially affect the Bank’s profitability and operations. 

10.2 Trust Fund. The Bank shall be responsible for the payment of all benefits provided under the Plan. At its discretion,
the Bank may establish one or more rabbi trusts, with such trustees as the Board may approve, for the purpose of providing for the payment of such benefits. Such rabbi trust or trusts may be irrevocable, but the assets thereof shall be subject to
the claims of the Bank’s creditors. To the extent any benefits provided under the Plan are actually paid from any such trust, the Bank shall have no further obligation with respect thereto, but to the extent not so paid, such benefits shall
remain the obligation of, and shall be paid by, the Bank. 
 10.3 Payment to Participant, Legal Representative or
Beneficiary. Any payment to any Participant or the legal representative, Beneficiary, or to any guardian or committee appointed for such Participant or Beneficiary in accordance with the provisions hereof, shall, to the extent thereof, be in
full satisfaction of all claims hereunder against the Bank, which may require the Participant, legal representative, Beneficiary, guardian or committee, as a condition precedent to such payment, to execute a receipt and release thereof in such form
as shall be determined by the Bank. 
 10.4 Nonassignability. Neither a Participant nor any other person shall
have any right to commute, sell, assign, transfer, hypothecate or convey in advance of actual receipt the amounts, if any, payable hereunder, or any part thereof, which are, and all rights to which are, expressly declared to be unassignable and
nontransferable. No part of the amounts payable shall, prior to actual payment, be subject to seizure or sequestration for the payment of any debts, judgments, alimony or separate maintenance owed by a Participant or any other person, nor be
transferable by operation of law in the event of a Participant’s or any other person’s bankruptcy or insolvency. 

10.5 Validity. In case any provision of this Plan shall be held illegal or invalid for any reason, said illegality or
invalidity shall not affect the remaining parts hereof, but this Plan shall be construed and enforced as if such illegal and invalid provision had never been inserted herein. 
 10.6 Notice. Any notice or filing required or permitted to be given to the Committee under the Plan shall be sufficient if in writing and hand delivered, or sent by registered or certified
mail, to any member of the Committee or the Secretary of the Bank. Such notice shall be deemed given as of the date of delivery or, if delivery is made by mail, as of the date shown on the postmark on the receipt for registration or certification.

 10.7 Successors. The provisions of this Plan shall bind and inure to the benefit of the Bank and its successors
and assigns. The term “successors” as used herein shall include any corporate or other business entity which shall, whether by merger, consolidation, purchase or otherwise acquire all or substantially all of the business and assets of the
Bank, and successors of any such corporation or other business entity.

 10.8 Payment of Employment and Code Section 409A Taxes. Any distribution
under this Plan shall be reduced by the amount of any taxes required to be withheld from such distribution. This Plan shall permit the acceleration of the time or schedule of a payment to pay employment related taxes as permitted under Treasury
Regulation Section 1.409A-3(j) or to pay any taxes that may become due at any time that the arrangement fails to meet the requirements of Code Section 409A and the regulations and other guidance promulgated thereunder. In the latter case,
such payments shall not exceed the amount required to be included in income as the result of the failure to comply with the requirements of Code Section 409A. 
 10.9 Acceleration of Payments. Except as specifically permitted herein or in other sections of this Plan, no acceleration of the time or schedule of any payment may be made hereunder.
Notwithstanding the foregoing, payments may be accelerated hereunder by the Bank, in accordance with the provisions of Treasury Regulation Section 1.409A-3(j)(4) and any subsequent guidance issued by the United States Department of the
Treasury. Accordingly, payments may be accelerated, in accordance with requirements and conditions of the Treasury Regulations (or subsequent guidance) in the following circumstances: (i) as a result of certain domestic relations orders;
(ii) in compliance with ethics agreements with the federal government; (iii) in compliance with ethics laws or conflicts of interest laws; (iv) in limited cash-outs (but not in excess of the limit under Code
Section 402(g)(1)(B)); (v) to apply certain offsets in satisfaction of a debt of the Participant to the Bank; (vi) in satisfaction of certain bona fide disputes between the Participant and the Bank; or (vii) for any other purpose
set forth in the Treasury Regulations and subsequent guidance.

made to the Participant pursuant to this Plan or otherwise are subject to and conditioned upon compliance with 12 U.S.C. § 1828(k) and 12 C.F.R. Part 359 Golden Parachute and Indemnification Payments or any other rules and regulations
promulgated thereunder. 
 10.11 Governing Law. The Plan is established under, and will be construed
according to, the laws of the Commonwealth of Massachusetts, to the extent such laws are not preempted by the ERISA or the Code and regulations published thereunder. 
 10.12 Non-Competition and Non-Solicitation. In the event the Participant has a vested SERP Account Balance under this Plan, the benefits provided to the Participant under this Plan are
specifically conditioned on the Participant’s covenant that, for a period of one (1) year following the Participant’s Separation from Service with the Bank, the Participant will not, without the written consent of the Bank, either
directly or indirectly: 
 (a) solicit, offer employment to, or take any other action intended (or that a
reasonable person acting in like circumstances would expect) to have the effect of causing any officer or employee of the Bank, or any of its respective subsidiaries or affiliates, to terminate his employment and accept employment or become
affiliated with, or provide services for compensation in any capacity whatsoever to, any business whatsoever that competes with the business of the Bank, or any of their direct or indirect subsidiaries or affiliates, that has headquarters or offices
within 25 miles of any location(s) in which the Bank has business operations or has filed an application for regulatory approval to establish an office (the “Restricted Territory”); 

(b) become an officer, employee, consultant, director, independent contractor, agent, joint venturer, partner or trustee
of any savings bank, savings and loan association, savings and loan holding company, credit union, bank or bank holding company, insurance company or agency, any mortgage or loan broker or any other entity that competes with the business of the Bank
or any of 

  
 10 









 
their direct or indirect subsidiaries or affiliates, that: (i) has headquarters within the Restricted Territory or (ii) has one or more offices, but is not headquartered, within the
Restricted Territory, but in the latter case, only if Participant would be employed, conduct business or have other responsibilities or duties within the Restricted Territory; or 

(c) solicit, provide any information, advice or recommendation or take any other action intended (or that a reasonable
person acting in like circumstances would expect) to have the effect of causing any customer of the Bank to terminate an existing business or commercial relationship with the Bank. 

In the event that the Participant violates any provision of this Section 10.12, all benefits payable to the Participant hereunder
shall cease and any benefits previously paid shall be reimbursed to the Bank within 30 days of Bank’s notification to the Participant that this provision has been violated. Notwithstanding anything in this Section 10.12 to the contrary, in
the event of the Participant’s termination of employment following a Change in Control, the Participant shall not be subject to the requirements of Sections 10.12(a), (b) or (c) above.

 Exhibit A 
 Supplemental Executive Retirement Plan 
 Participation Agreement

             , 2014 

I,                     , and Pilgrim Bank
hereby agree, for good and valuable consideration, the value of which is hereby acknowledged, that I shall participate in the Supplemental Executive Retirement Plan (“Plan”) established as of January 1, 2014, by Pilgrim Bank,
as such Plan may now exist or hereafter be modified, and do further agree to the terms and conditions thereof. 
 I understand that I must
execute this Supplemental Executive Retirement Plan Participation Agreement (“Participation Agreement”) as well as notify the Committee of such execution in order to participate in the Plan. The provisions of the Plan are
incorporated herein by reference. In the event of an inconsistency between the terms of this Participation Agreement and the Plan, the terms of the Plan shall control. Any elections that I may make in this Participation Agreement must be made on my
initial entry into the Plan. 
 The following provisions relate to a determination of my Account Balance under the Plan. 

Benefit Age. My Benefit Age is age     . 
 Annual Contribution. A fixed      percent of my annual rate Base Salary (in effect as of the last day of the Plan Year) will be contributed by the Bank to my SERP
Account. 
 Discretionary Contribution. In the sole discretion of the Board, a Discretionary Contribution may be allocated to my
SERP Account from time to time. 
 Vesting Rate. At the completion of      Years of Service from the
beginning of the Plan Year in which I am eligible to participate, I will be 100% vested in my SERP Account Balance.  

Distribution Upon Attainment of Benefit Age. I understand that within 30 days after attainment of my Benefit Age, I shall be entitled to my
SERP Account Balance, calculated in accordance with all relevant provisions of the Plan. My SERP Account Balance will be paid in a cash lump sum payment unless I elect otherwise by checking the box below. 

 

	 	 ̈	In lieu of a lump sum payment, I elect Annual Installments for     Years (not to exceed 10 years) 


Separation from Service Prior to Benefit Age. If I have a vested SERP Account Balance at the time of my voluntary or involuntary Separation
from Service without Cause (as defined in the Plan) prior to attainment of my Benefit Age (other than due to Death or Disability or a Change in Control pursuant to Section 6.5 of the Plan), I shall be entitled to the vested portion of my SERP
Account Balance, calculated in accordance with all relevant provisions of the Plan. My SERP Account Balance will be paid within 30 days after my Separation from Service in a cash lump sum payment unless I elect otherwise by checking the box below.









	 	 ̈	In lieu of a lump sum payment, I elect Annual Installments for     Years (not to exceed 10 years) 


Termination for Cause. I understand that if I have a Termination for Cause, my entire SERP Account Balance under this Plan shall be
forfeited. 
 Death Benefit. In the event of my death prior to Separation from Service with the Bank, my Beneficiary shall be
entitled to my entire SERP Account Balance, calculated in accordance with the Plan and payable in a lump sum payment within 30 days after my death. 
 Change in Control Occurs Before Separation from Service. I understand that if there is a Change in Control and within 24 months thereafter I have an involuntary Separation from Service or
resign for Good Reason, I will be entitled to my entire SERP Account Balance. In addition, my SERP Account Balance will be increased by three (3) additional Annual Contributions (or the number of additional Annual Contributions that would have
been made prior to the attainment of my Benefit Age, if less). My SERP Account Balance shall be paid within 30 days after my Separation from Service) in a cash lump sum payment. I understand that if there is a Change in Control and I voluntarily
terminate employment (other than for Good Reason), I will be entitled only to the vested portion of my SERP Account Balance, calculated without regard to the Change in Control. 
 Disability While Employed. I understand that in the event of my Disability while employed with the Bank, I will be entitled my entire SERP Account Balance calculated as set forth in the
Plan. My Disability Benefit will be paid in a cash lump sum payment within 30 days after my Separation from Service due to Disability. 

Notwithstanding anything in this Participation Agreement to the contrary, if I am a “Specified Employee” (as defined in the Plan) at the time
of my Separation from Service (for reasons other than death or Disability), my SERP Account Balance hereunder shall be held by the Bank and distributed to me commencing on the first day of the seventh month following my Separation from Service
pursuant to Section 6.7 of the Plan. 
 This Participation Agreement shall become effective upon execution below by me as the
