Exhibit 10.10(a)



 Exhibit 10.10(a) 
 FIRST AMENDMENT TO 
 THE PEOPLE’S UNITED BANK ENHANCED SENIOR PENSION
PLAN 
 WHEREAS, People’s United Bank, a federally chartered savings bank (the “Bank”), maintains The
People’s United Bank Enhanced Senior Pension Plan (the “Plan”) for a select group of management or highly compensated employees who meet certain qualifications; and 

WHEREAS, the provisions of Section 11.1 provide that the Plan may be amended from time to time by the Bank’s Human
Resources Committee (the “Committee”); and 
 WHEREAS, the Committee on July 6, 2011, determined to amend
the Plan to: (i) provide that no Plan Participant’s compensation earned or paid after December 31, 2011, or service performed after such date shall be taken into account under the Plan in determining such Participant’s benefit
thereunder, but that service after December 31, 2011, nonetheless shall be taken into account under the Plan solely for purposes of determining such Participant’s vesting in his Plan Benefit accrued as of December 31, 2011; and
(ii) that no employee who has not become a Participant in the Plan before January 1, 2012, shall be eligible to participate in the Plan on or after such date; and 
 WHEREAS, the Committee on October 13, 2011, determined to modify such action of July 6. 2011 to allow an Employee who is such as of January 1, 2012, had attained the Minimum Salary
Grade prior to March 1, 2008 and remains at a salary grade at least equal to die Minimum Salary Grade to become a Participant as of his attainment of age fifty (50) on or after January 1, 2012; and 

WHEREAS, the Committee on December 15, 2011, determined to amend the Plan to provide for an early payment for each
Participant in an amount sufficient to pay the Participant’s portion of the FICA withholding taxes attributable to the ascertainable benefit amount under the Plan and an additional amount estimated to pay the applicable state and federal income
withholding taxes and FICA withholding taxes relating to such payment and any related “gross-up” payment; and, further, to provide for an offset against the Plan Benefit payable following such Participant’s termination of employment
to reflect such early payment; and 
 WHEREAS, the undersigned officer has been duly authorized by the Bank to execute
such amendments. 
 NOW, THEREFORE, the Bank hereby amends the Plan, as follows, effective December 31, 2011, except
as otherwise provided herein: 
  

	 	1.	A new paragraph is added to the end of ARTICLE I of the Plan to read as follows: 

 “Benefits under the Plan, the Cap Excess Plan and the ERP have been frozen effective December 31, 2011, and no increases shall be made to a Participant’s benefit in the Plan determined as
of December 31, 2011, as a result of service performed for the Bank on and after January 1, 2012. Any Employee who was initially employed by the Bank before August 14, 2006, who had not become a Participant in the Plan by
December 31, 2011, but would qualify as a Participant under Article III of the Plan 







 
except that he has not attained age 50 by December 31, 2011 shall nonetheless be eligible to become a Participant in the Plan if he attains age 50 on or after January 1, 2012 while he
is an Employee of the Bank. No Participant’s compensation earned or paid after December 31, 2011, shall become part of his Final Average Salary and no part of his service performed after such date shall be taken into account under the Plan
in determining the Participant’s Plan Benefit or Plan Death Benefit hereunder. The provisions above limiting recognition of a Participant’s Credited Service after December 31, 2011, shall not be construed to indicate that the
Participant has had a termination of Credited Service requiring distribution under the Plan.” 
  

	 	2.	For purposes of clarification, the following sentence is added to the end of Section 2.25: 


“For purposes of determining (a) above, no service performed or attributed to periods after December 31, 2011 and no amount
of compensation paid to or accrued by the Participant after December 31, 2011 shall be considered in determining his Final Average Salary or Target Amount. In determining whether a Participant has completed less than 15 Years of Credited
Service, Credited Service performed by the Participant after December 31, 2011 shall not be considered.” 
  

	 	3.	Section 3.2 of the Plan is amended in its entirety to read as follows: 


“3.2. Subsequent Participants. Subject to the provisions of Section 3.4 hereof, each other Employee who
is such on or after the Effective Date shall become a Participant as of the date he meets both of the following requirements: 
 (a) has a salary grade equal to or higher than the Minimum Salary Grade; and 
 (b) has attained age 50 or older. 
 For purposes of clarification, the Employee may
satisfy the requirement of Section 3.2(b) after December 31, 2011 and become a Participant if he satisfies all other requirements prior to such date, namely: initially an Employee prior to August 14, 2006; attained a salary grade at
least equal to the Minimum Salary Grade prior to March 1, 2008; and remains an Employee and maintains such a salary grade until attaining age 50.” 
  

	 	4.	Section 5.5 is added to the Plan, effective December 15, 2011, to read as follows: 


“5.5 Withholding Taxes. The Bank shall pay such amounts as come due under any Federal, state or local laws or
regulations such as the provisions of Sections 3121(v) and 3401(a) of the Code to the proper governmental agencies (i) with respect to the Participant’s share of FICA taxes attributable to his benefits under the Plan; (ii) income tax
withholding on the amount of the such taxes, and (iii) any withholding taxes attributable to the amounts of such withholding described in (i) and (ii) so that the Participant’s out of pocket payment of taxes is not increased
because of his participation in the Plan for a year in which no distribution of Plan Benefits is made (such payments described in (iii) being sometimes known as “gross-ups”). Further,


  
 2 








 
with respect to actual distribution of Plan Benefits (other than those provided for in the immediately preceding sentence) the Bank shall make such provisions and take such action as it may deem
necessary or appropriate for the withholding of any taxes which the Bank is required by any law or regulation of any governmental authority, whether Federal, state or local, to withhold in connection with such payment. Any amounts paid by the Bank
pursuant to any provision of this Section shall be subtracted from the payment to such Participant or his Beneficiary of Ins Plan Benefit or death benefit.” 
  

	 	5.	Section 11,2 of the Plan is modified in its entirety to read as follows: 


“11.2 Minimum Benefit. Further, no Participant who was a participant in the SRP as of the day before the
Effective Date shall receive a Plan benefit which, when added to the plan benefit to which he is entitled under the Cap Excess Plan is of a lesser actuarial value than the Plan Benefits such Participant would have received under the SRP had the SRP
not been amended as of the Effective Date based on the lesser of his Final Average Salary as of the earlier of (i) the date of termination of his Credited Service, or (ii) the Effective Date, or her or his Final Average Salary as of
December 31, 2011 ” 
  

	 	6.	The second sentence of Section 11.4 of the Plan is amended to read as follows: 


“Further, the Bank may cease all further benefit accruals, and has done so, effective December 31, 2011.” 

 

	 	7.	Section 14.1(e) is added to the Plan to read as follows: 

 (e) Notwithstanding any provision of this Article XIV to the contrary, a Participant’s Credited Service performed after December 31, 2011, shall not be considered under the Plan in determining
his Target Amount or his Plan Benefit hereunder. Nonrecognition of a Participant’s Credited Service performed after December 31, 2011, shall not be deemed a termination of the Participant’s Credited Service for purposes of allowing a
distribution under the Plan. Notwithstanding the above, Years of Vesting Service performed after December 31, 2011, will be recognized by the Plan solely for purposes of satisfying the vesting requirements under Article IV of the Plan.”
