                     CHANGE OF CONTROL SEVERANCE AGREEMENT
                     -------------------------------------

     THIS AGREEMENT between BJ's Wholesale Club, Inc., a Delaware corporation
(the "Company",), and John J. Nugent ("Executive"), dated as of February 4,
1999.

     Executive is a key executive of the Company or a Subsidiary and an integral
part of its management.

     The Company recognizes that the possibility of a Change of Control or
Potential Change of Control of the Company may result in the departure or
distraction of management to the detriment of the Company and its shareholders
and wishes to modify and restate the agreement previously applicable under such
circumstances.

     The Company wishes to assure Executive of fair severance should Executive's
employment terminate in specified circumstances following a Change of Control or
Potential Change of Control of the Company and to assure Executive of certain
other benefits upon such event.

     In consideration of Executive's continued employment with the Company or a
Subsidiary and other good and valuable consideration, the parties agree as
follows:

     1.   Benefits Upon Change of Control.
          -------------------------------

     1.1  In General. Within 30 days following the earlier of a Change of
          ----------
Control or Potential Change of Control (such earlier event to be a "Control
Event") as long as this Agreement had not been terminated under Section 8.6 at
the time of the Control Event, then whether or not Executive's employment has
been terminated following the Control Event, the Company shall pay to Executive
the following in a lump sum:

          (a) an amount equal to the product of (i) the "Target Bonus" under the
     Company's Management Incentive Plan or any other annual incentive plan
     which is applicable to Executive for the fiscal year in which the Control
     Event occurs (or if the Target Bonus is reduced within 180 days before the
     commencement of a Standstill Period, the "Target Bonus" applicable to
     Executive for the fiscal year in which such reduction occurred) and (ii) a
     fraction, the numerator of which is the number of days in such fiscal year
     prior to the Control Event and the denominator of which is 365; and
<PAGE>

          (b) if Executive is a participant in a performance-based long-range
     incentive plan at the time of a Control Event, such amount as is required
     to be paid to Executive upon a Control Event pursuant to the provisions of
     such plan; provided, that if such incentive plan does not provide for an
     automatic payment on the earlier of a Change of Control or a Potential
     Change of Control, then any payment under such incentive plan shall be made
     only as and when provided for in such incentive plan even though the
     benefit under Section 1.1(a) above has been paid previously.

     1.2  Benefits Following Qualified Termination of Employment. Executive
          ------------------------------------------------------
shall be entitled to the following benefits upon a Qualified Termination:

          (a) Within 30 days following the Date of Termination, the Company
     shall pay to Executive the following in a lump sum:

               (i)   an amount equal to three times Executive's Base Salary for
          one year at the rate in effect immediately prior to the Date of
          Termination or, if higher, the Control Event (or if Executive's Base
          Salary was reduced within 180 days before the commencement of a
          Standstill Period, the rate in effect immediately prior to such
          reduction), plus the accrued and unpaid portion of Executive's Base
          Salary through the Date of Termination. Any payments made to Executive
          under any long term disability plan of the Company with respect to the
          three years following termination of employment shall be offset
          against such three times Base Salary payment. Executive shall promptly
          make reimbursement payments to the Company to the extent any such
          disability payments are received by Executive after the Base Salary
          payment; and

               (ii)  an amount equal to three times Executive's automobile
          allowance for one year at the rate in effect immediately prior to the
          Date of Termination or, if higher, the Control Event (or if such
          automobile allowance was reduced within 180 days before the
          commencement of a Standstill Period, the rate in effect immediately
          prior to such reduction unless such reduction was offset by an
          increase in Base Salary during such 180-day period), plus any portion
          of Executive's automobile allowance payable but unpaid through the
          Date of Termination; and

               (iii) an amount equal to three times the Target Bonus amount, as
          defined and determined under Section 1.1(a) above without any
          fractional adjustment.

          (b) Until the third anniversary of the Date of Termination, the
     Company shall maintain in full force and effect for the continued benefit
     of Executive and Executive's family all life insurance and medical
     insurance (other than long-term disability) plans and programs in which
     Executive was entitled to participate immediately prior to the Control
     Event (or if Executive's title was changed to a level below that of
     Executive's Current Title within 180 days before the commencement of a
     Standstill Period, all such plans and programs in which Executive was
     entitled to participate immediately prior to such change,

                                      -2-
<PAGE>

     if the benefits thereunder are greater), provided that Executive's
     continued participation is possible under the general terms and provisions
     of such plans and programs. In the event that participation in such plans
     or programs is not available to Executive for any reason, including
     termination of the plan, the Company shall arrange upon comparable terms to
     provide Executive with benefits substantially similar to those which
     Executive is entitled to receive under such plans and programs.
     Notwithstanding the foregoing, the Company's obligations hereunder with
     respect to life insurance or medical insurance plans and programs shall be
     deemed satisfied to the extent (but only to the extent) of any such
     insurance coverage or benefits provided by another employer.

          (c) If Qualified Termination occurs by reason of Disability, the
     Company shall maintain in full force and effect for the continued benefit
     of Executive, disability benefits and/or disability insurance at the same
     level to which Executive was entitled immediately prior to the Qualified
     Termination.

     1.3  Coordination With Certain Tax Rules.
          -----------------------------------

          (a) Notwithstanding any other provision of this Agreement, 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 Executive
     a portion of any "Contingent Compensation Payments" that Executive would
     otherwise be entitled to receive to the extent necessary to eliminate any
     "excess parachute payments" (as defined in Section 280G(b)(1) of the
     Internal Revenue Code of 1986, as amended (the "Code")) for Executive. For
     purposes of this Section 1.3, the Contingent Compensation Payments so
     eliminated shall be referred to as the "Eliminated Payments" and the
     aggregate amount (determined in accordance with Proposed 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."

          (b) For purposes of this Section 1.3, 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 Code.

               (ii) "Contingent Compensation Payments" shall mean any payment
          (or benefit) in the nature of compensation that is made or made
          available (under this Agreement 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.

          (c) Any payments or other benefits otherwise due to the Executive
     following a Change in Ownership or Control that could be characterized (as
     reasonably determined by

                                      -3-
<PAGE>

     the Company) as Contingent Compensation Payments shall not be made until
     the determination, pursuant to this Section 1.3(c), of which Contingent
     Compensation Payments shall be treated as Eliminated Payments. Within 30
     days after each date on which the Executive first becomes entitled to
     receive (whether or not then due) a Contingent Compensation Payment
     relating to such Change in Ownership or Control, the Company shall
     determine and notify Executive (with reasonable detail regarding the basis
     for its determinations) (i) which of such payments and benefits constitute
     Contingent Compensation Payments and (ii) the Eliminated Amount. Within 30
     days after delivery of such notice to Executive, Executive shall notify the
     Company which Contingent Compensation Payments, or portions thereof (the
     aggregate amount of which, determined in accordance with Proposed Treasury
     Regulation Section 1.280G-1, Q/A-30 or any successor provision, shall be
     equal to the Eliminated Amount), shall be treated as Eliminated Payments.
     In the event that Executive fails to notify the Company pursuant to the
     preceding sentence on or before the required date, the Contingent
     Compensation Payments (or portions thereof) that shall be treated as
     Eliminated Payments shall be determined by the Company in its absolute
     discretion.

          (d) The provisions of this Section 1.3 are intended to apply to any
     and all payments or benefits available to Executive under this Agreement or
     any other agreement or plan of the Company under which Executive receives
     Contingent Compensation Payments.

Cause or other than for good reason (as defined in paragraph (k) of Exhibit A)
or in obtaining any right or benefit to which Executive is entitled under this
Agreement. Any amount payable under this Agreement that is not paid when due
shall accrue interest at the prime rate as from time to time in effect at

     (II)    Executive's rate of Base Salary for any fiscal year is less than
             100 percent of the rate of Base Salary paid to Executive in the
             completed fiscal year immediately preceding the Control Event, or
             Executive's total cash compensation opportunities, including
             salary, auto allowance, and incentives, for any fiscal year are
             less than 100 percent of the total cash compensation opportunities
             made available to Executive in the completed fiscal year
             immediately preceding the Control Event, unless any such reduction
             represents an overall reduction of no more than 5 percent of the
             rate of Base Salary paid or cash compensation opportunities made
             available, as the case may be, and affects all other executives in
             the same organizational level (it being the Company's burden to
             establish this fact); or

     (III)   the failure of the Company (or a Subsidiary) to continue in effect
             any benefits or perquisites, or any pension, life insurance,
             medical insurance or disability plan in which Executive was
             participating immediately prior to the Control Event (the
             "Benefits," individually, a "Benefit") unless the Company (or a
             Subsidiary) provides Executive with substantially similar Benefits,
             or the taking of any action by the Company (or a Subsidiary) that
             would adversely affect Executive's participation in or materially
             reduce any of Executive's Benefits or deprive Executive of any
             material Benefit enjoyed by Executive immediately prior to the
             Control Event, unless any elimination or reduction of any Benefit,
             or any adverse effect on Executive's participation, has an
             aggregate value equal to no more than 5 percent of the Benefits,
             and affects all other executives in the same organizational level
             (it being the Company's burden to establish this fact); or

     (IV)    any purported termination of Executive's employment by the Company
             (or a Subsidiary) for Cause during a Standstill Period which is not
             effected in compliance with paragraph (b) of this Exhibit; or

     (V)     any relocation of Executive of more than 40 miles from the place
             where Executive was located at the time of the Control Event; or

     (VI)    any other breach by the Company of any provision of this Agreement;
             or

     (VII)   the Company sells or otherwise disposes of, in one transaction or a
             series of related transactions, assets or earning power aggregating
             more than 30 percent of the assets (taken at asset value as stated
             on the books of the Company determined in accordance with generally
             accepted accounting principles consistently applied) or earning
             power of the Company (on a non-consolidated basis) or the Company
             and its Subsidiaries (on a consolidated basis) to any other Person
             or Persons (as defined in Exhibit B); or

     (VIII)  if Executive is employed by a Subsidiary of the Company, such
             Subsidiary either ceases to be a Subsidiary of the Company or sells
             or otherwise disposes of, in one transaction or a series of related
             transactions, assets or earning power aggregating more than 30
             percent of the assets (taken at asset value as stated on the books
             of the Subsidiary determined in accordance with generally accepted
             accounting

             Subsidiary (on a non-consolidated basis) or such Subsidiary and its
             subsidiaries (on a consolidated basis) to any other Person or
             Persons (as defined in Exhibit B); or

     (IX)    the voluntary termination by Executive of Executive's employment at
             any time during the period commencing eight months plus one day
             after the Change of Control and ending 12 months after the Change
             of Control, provided, that in the event of any such voluntary
                         --------
             termination pursuant to this clause (IX), the Executive shall be
             entitled to receive only one-third (1/3) of the lump sum amount
             provided for in Section 1.2(a) of this Agreement and the benefits
             provided for in Section 1.2(b) shall be provided for one year
             rather than three years from the Date of Termination.

     (l) "Standstill Period" shall be the period commencing on the date of a
Control Event and continuing until the close of business on the last business
day of the 24th calendar month following a Change of Control; provided, however,
if no Change of Control occurs within 12 months of a Potential Change of
Control, then the Standstill Period that began as a result of such Potential
Change of Control shall end on the close of business on the last business day of
the 12th calendar month following such Potential Change of Control.

     (m) "Subsidiary" shall mean any corporation in which the Company owns,

                        Definition of Change of Control
                        -------------------------------

A    "Change of Control" shall mean:

     (a) The acquisition by an individual, entity or group (within the meaning

either (i) the then-outstanding shares of common stock of the Company (the
"Outstanding Company Common Stock") or (ii) the combined voting power of the
then-outstanding voting securities of the Company entitled to vote generally in
the election of directors (the "Outstanding Company Voting Securities");
provided, however, that for purposes of this subsection (a), the following
--------  -------
acquisitions shall not constitute a Change of Control: (i) any acquisition
directly from the Company, (ii) any acquisition by the Company, (iii) any
acquisition by any employee benefit plan (or related trust) sponsored or
maintained by the Company or any corporation controlled by the Company, or (iv)
any acquisition by any corporation pursuant to a transaction which satisfies the

definition; or

     (b) Individuals who, as of the date hereof, constitute the Board of
Directors of the Company (the "Incumbent Board") cease for any reason to
constitute at least a majority of the Board; provided, however, that any
                                             --------  -------
individual becoming a director subsequently to the date hereof whose election,
or nomination for election by the Company's stockholders, was approved by a vote
of at least a majority of the directors then comprising the Incumbent Board
shall be considered as though such individual were a member of the Incumbent
Board (except that this proviso shall not apply to any individual whose initial
assumption of office as a director occurs as a result of an actual or threatened
election contest with respect to the election or removal of directors or other
actual or threatened solicitation of proxies or consents by or on behalf of a
Person other than the Board); or

     (c) Consummation of a reorganization, merger or consolidation involving the

Outstanding Company Common Stock and Outstanding Company Voting Securities
immediately prior to such Business Combination beneficially own, directly or
indirectly, more than 60% of, respectively, the then-outstanding shares of
common stock and the combined voting power of the then-outstanding voting
securities entitled to vote generally in the election of directors, of the
corporation resulting from such Business Combination (which as used in Section
(c) of this definition shall include, without limitation, a corporation which as
a result of such transaction owns the Company or all or substantially all of the
Company's assets either directly or through one or more subsidiaries) in
substantially the same proportions as their ownership, immediately prior to such
Business Combination, of the outstanding Company Common Stock and Outstanding

Combination) beneficially owns, directly or indirectly, 20% or more of,
respectively, the then outstanding shares of common stock of the corporation
resulting from such Business Combination, or the combined voting power of the
then-outstanding voting securities of such corporation and (iii) at least half
of the members of the board of directors of the corporation resulting from such
Business Combination were members of the Incumbent Board at the time of the
