BJ’S WHOLESALE CLUB, INC.

AMENDMENT NO. 1 TO CHANGE OF CONTROL SEVERANCE BENEFIT PLAN

FOR KEY EMPLOYEES

The BJ’s Wholesale Club, Inc. Change of Control Severance Benefit Plan for Key
Employees, Amended and Restated January 31, 2010 (the “Plan”), is amended as of
March 24, 2011, as follows:

Section 1.02(b) of the Plan is amended by deleting all text in the first
sentence following “Exhibit B”. The first sentence of Section 1.02(b) will now
read as follows:

 

  “(b) In addition to amounts described in paragraph (a) above, the Employer
shall within 30 days following the Participant’s Date of Termination pay in a
single lump sum an amount equal to the Participant’s Base Salary, determined as
hereinafter provided, multiplied by the Applicable Number of Weeks, determined
as provided on Exhibit B.”

Section 1.03 of the Plan is deleted in its entirety and replaced by the
following:

 

  “1.03 Coordination With Certain Tax Rules.

 

  (a) In the event that the Company undergoes a Change in Ownership or Control
(as defined below), the Company shall not be obligated to provide to the
Participant a portion of any Contingent Compensation Payments (as defined below)
that the Participant would otherwise be entitled to receive to the extent
necessary to eliminate any Excess Parachute Payments (as defined below) for the
Participant. For purposes of this Section 1.03, the Contingent Compensation
Payments so eliminated shall be referred to as the “Eliminated Payments” and the
aggregate amount (determined in accordance with Treasury Regulation
Section 1.280G-1, Q/A-30 or any successor provision) of the Contingent
Compensation Payments so eliminated shall be referred to as the “Eliminated
Amount.” Notwithstanding any other provision of this Plan, if the Eliminated
Amount for the Participant equals or exceeds the sum of:

 

  (i) the Threshold Amount (as defined below), plus

 

  (ii) the Income Tax Payable on the Eliminated Amount (as defined below), plus

 

  (iii)

the Excise Tax Payable on Excess Parachute Payments (as defined below),

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

 

no portion of any Contingent Compensation Payments shall be eliminated for the
Participant.

 

  (b) For purposes of this Section 1.03, the following terms shall have the
following respective meanings:

 

  (i) “Change in Ownership or Control” shall mean a change in the ownership or
effective control of the Company or in the ownership of a substantial portion of
the assets of the Company determined in accordance with Section 280G(b)(2) of
the Internal Revenue Code of 1986, as amended (the “Code”).

 

  (ii) “Contingent Compensation Payments” shall mean any payment (or benefit) in
the nature of compensation that is made or made available (under this Plan or
otherwise) to a “disqualified individual” (as defined in Section 280G(c) of the
Code) and that is contingent (within the meaning of Section 280G
(b) (2) (A) (i) of the Code) on a Change in Ownership or Control of the Company.

 

  (iii) “Excess Parachute Payments” shall mean “excess parachute payments” as
defined in Section 280G(b)(1) of the Code before taking into account the
Eliminated Amount, if otherwise applicable.

 

  (iv) “Threshold Amount” shall mean $25,000.

 

  (v) “Income Tax Payable on the Eliminated Amount” shall mean the Eliminated
Amount (determined without regard to whether any Contingent Compensation
Payments are actually eliminated) multiplied by the highest combined marginal
federal, state and local income tax rate in effect for the taxable year, taking
into account the phase-out of itemized deductions and the federal Medicare tax.

 

  (vi) “Excise Tax Payable on Excess Parachute Payments” shall mean the tax
imposed by Section 4999(a) of the Code on Excess Parachute Payments.

 

  (c)

Within 45 days after each date on which the Participant first becomes entitled
to receive (whether or not then due) payments or benefits relating to a Change
in Ownership or Control, the Company, at its expense, shall engage a nationally
recognized law firm or a nationally recognized accounting firm, which may be the
regular law firm or accounting firm of the Company (the “280G Firm”), to
determine (i) which of such payments and benefits constitute Contingent
Compensation Payments, (ii) the Eliminated Amount and (iii) the Eliminated
Payments. To identify the Eliminated Payments, the 280G Firm shall determine the

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

 

“Contingent Compensation Payment Ratio” (as defined below) for each Contingent
Compensation Payment and then reduce the Contingent Compensation Payments in
order beginning with the Contingent Compensation Payments with the highest
Contingent Compensation Payment Ratio. For Contingent Compensation Payments with
the same Contingent Compensation Payment Ratio, such Contingent Compensation
Payments shall be reduced based on the time of payment of such Contingent
Compensation Payments, with amounts having later payment dates being reduced
first. For Contingent Compensation Payments with the same Contingent
Compensation Payment Ratio and the same time of payment, such Contingent
Compensation Payments shall be reduced on a pro rata basis (but not below zero)
prior to reducing Contingent Compensation Payments with a lower Contingent
Compensation Payment Ratio. The term “Contingent Compensation Payment Ratio”
shall mean a fraction, the numerator of which is the value of the applicable
Contingent Compensation Payment that must be taken into account at the change in
control date for purposes of Section 280G of the Code, and the denominator of
which is the present value at the change in control date of the actual amount to
be received in respect of the applicable payment (e.g., in the case of equity
grants, the denominator shall be determined by reference to the fair market
value of the equity at the relevant dates and not in accordance with the
methodology for accelerated payments set forth in Treasury Regulation
Section 1.280G-1Q/A 24(b) or (c)).

 

  (d) Within 30 days after each date on which the Participant first becomes
entitled to receive (whether or not then due) payments or benefits relating to
such Change in Ownership or Control, the Company shall provide notice to the
Participant with reasonable detail of (i) which payments and benefits
constitute Contingent Compensation Payments, (ii) the Eliminated Amount and
(iii) the Eliminated Payments.

 

  (e) In the event of any underpayment or overpayment hereunder, as determined
by the 280G Firm, the amount of such underpayment or overpayment shall within 30
days of such determination be paid to the Participant or refunded to the
Company, as the case may be, with interest at the applicable federal rate
provided for in Section 7872(f)(2) of the Code.”

Exhibit B to the Plan shall be deleted and replaced in its entirety with the
attached Exhibit B.

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

IN WITNESS WHEREOF, BJ’s Wholesale Club, Inc. has caused this instrument to be
duly executed in its name and on its behalf as of the date first above written.
