 NISOURCE INC. 
 EXECUTIVE DEFERRED COMPENSATION PLAN 
 ARTICLE I 

BACKGROUND AND PURPOSE 
 1.1 Background. Effective November 1, 2000, the Bay State Gas Company Key Employee Deferred Compensation Plan (the “Bay State Plan”) was merged into the NIPSCO Plan and the
NIPSCO Plan was renamed the NiSource Inc. Executive Deferred Compensation Plan (the “Plan”). Effective January 1, 2004, the Columbia Energy Group Deferred Compensation Plan (the “Columbia Plan”) was merged into the Plan.
Effective January 1, 2005, the Plan was amended and restated to comply with Code Section 409A, and guidance and regulations thereunder. Deferred Compensation, Discretionary Contributions, and earnings thereon, earned and vested prior to
January 1, 2005 shall be administered without giving effect to Code Section 409A, and guidance and regulations thereunder. Effective January 1, 2008, the Plan was amended and restated to incorporate the provisions of amendments to the
Plan since the January 1, 2005, amendment and restatement and to allow participants to elect to participate in the Plan only during the applicable enrollment period or at such later date allowed under Code Section 409A for certain
performance based bonuses. 
 The Plan is hereby amended and restated effective as of May 13, 2011 to transfer all
administrative authority with respect to the Plan (including the authority to render decisions on claims and appeals and make administrative or ministerial amendments) from the ONC Committee to the Benefits Committee. 

1.2 Purpose. The purpose of this Plan is to provide current tax planning opportunities as well as supplemental funds for
retirement or death for selected employees of an Employer. It is intended that the Plan will aid in attracting and retaining employees of exceptional ability by providing them with these benefits.

and (2) any other key employee of an Employer who is designated from time to time by the ONC Committee.

Account with a Discretionary Contribution. 

  
 4 

 3.3 Amendment of Eligibility Criteria. The ONC Committee may, in its
discretion, change the criteria for eligibility for any reason, provided, however, that no change in the criteria for eligibility shall be effective unless such changes are (a) within guidelines established by the ONC Committee or
(b) approved by the ONC Committee. Eligibility for participation in one year does not guarantee eligibility to participate in any future year. 
 ARTICLE IV 
 DEFERRAL COMMITMENTS 

4.1 Timing of Deferral Elections. An Eligible Employee may elect to defer Compensation for services performed in any
Deferral Period by submitting an Election Form to the Retirement Committee only during the annual enrollment period, established by the Retirement Committee, which shall end no later than December 31, of the year preceding such Deferral Period.
Thus, for any salary to be paid for services performed in a year, an election to defer such salary must be made no later than December 31, of the prior year. Further, except as provided in Section 4.1(b) below, for annual incentive awards
paid for services performed in a year, an election to defer such annual incentive award must be made no later than December 31, of the prior year. To illustrate these provisions, an election to defer salary payable for services performed in
2008 must be made by December 31, 2007. Further, an election to defer annual incentive awards that are (1) not performance-based compensation described in Section 4.1(b) below, (2) earned for the 2009 calendar year, and
(3) to be paid in March 2010, must be made by December 31, 2008. 
 4.2 Amount of Deferral. A
Participant may make a Deferral Commitment in the Election Form as follows: 
  

	 	(a)	Base Compensation Deferral Commitment. The amount of base Compensation that a Participant may elect to defer in a Compensation Deferral Commitment shall be
stated as a whole percentage of base Compensation from five percent (5%) to 80%; provided, however, that the Company may reduce the amount deferred to the extent necessary to satisfy federal, state, local, or other tax withholding obligations
and employee benefit plan withholding requirements. 

  

	 	(b)	Annual Incentive Deferral Commitment. The amount of any annual incentive award that a Participant may elect to defer in a Compensation Deferral Commitment shall
be stated as a whole percentage of the annual incentive award from five percent (5%) to 100%; provided, however, that the Company may reduce the amount deferred to the extent necessary to satisfy federal, state, local, or other tax withholding
obligations and employee benefit plan withholding requirements. 

  

	 	(c)	No Deferral Commitment shall be made subsequent to the date of a Participant’s separation from service with all Employers. 

4.3 Distribution Options. Each Deferral Commitment with respect to a calendar year shall specify the date on which the
applicable deferred amount and earnings thereon shall be distributed. Such date shall be the first to occur of (1) the date of the Participant’s separation from service with all Employers; or (2) a date selected by the Participant,
provided that a selected date must be at least one year after the date the deferred amount would have been paid to the Participant in cash in the absence of the election to make the deferral. 

  
 5 

 4.4 Duration of Deferral Commitment. A Participant shall make an election in
his Election Form as to the time and form of payment of the Deferral Commitment for each Deferral Period. A Participant’s Deferral Commitment for any Deferral Period is effective only for such Deferral Period in order to defer Compensation for
a subsequent Deferral Period, an Eligible Employee must file a new deferral election with respect to such Compensation. A Participant shall not be required to designate the same time and form of payment for each Deferral Period. 

4.5 Modification of Deferral Commitment. Except as provided otherwise in this Plan, Deferral Commitments shall be
irrevocable. 
 4.6 Change in Employment Status. If the Plan Administrator determines that a Participant’s
performance is no longer at a level that deserves reward through participation in the Plan, but does not terminate the Participant’s employment with an Employer, the Participant’s existing Deferral Commitment shall terminate at the end of
the current Deferral Period, and no new Deferral Commitment may be made by such Participant for any Deferral Period beginning after notice of such determination is given by the Plan Administrator. 

ARTICLE V 
 DEFERRED COMPENSATION ACCOUNT 
 5.1 Account. The
Compensation deferred by a Participant under the Plan, including any Discretionary Contributions and earnings thereon, shall be credited to the Participant’s Account. Separate subaccounts may be maintained to reflect different forms of
distribution, investment options, levels of vesting, and forms of payment. The Account shall be a bookkeeping device utilized for the sole purpose of determining the benefits payable under the Plan and shall not constitute a separate fund of assets.

 5.2 Timing of Credits; Withholding. A Participant’s deferred Compensation shall be credited to the
Participant’s Account at the time it would have been payable to the Participant. Any withholding of taxes or other amounts with respect to deferred Compensation that is required by federal, state or local law shall be withheld from the
Participant’s nondeferred Compensation to the maximum extent possible and any remaining amount shall reduce the amount credited to the Participant’s Account. 
 5.3 Discretionary Contributions. An Employer may make Discretionary Contributions to a Participant’s Account. Discretionary Contributions shall be credited at such times and in such
amounts as the ONC Committee in its sole discretion shall determine. 

  
 6 

 5.4 Determination of Account. Each Participant’s Account as of each
Determination Date shall consist of the balance of the Account as of the immediately preceding Determination Date, adjusted as follows: 
  

	 	(a)	New Deferrals. The Account shall be increased by any deferred Compensation credited since such preceding Determination Date. 

 

	 	(b)	Discretionary Contributions. The Account shall be increased by any Discretionary Contributions credited since such preceding Determination Date.

  

	 	(c)	Distributions. The Account shall be reduced by any benefits distributed from the Account to the Participant since such preceding Determination Date.

  

	 	(d)	Valuation of Account. The Account shall be increased or decreased by the aggregate earnings, gains and losses on such Account since such preceding Determination
Date. 

 5.5 Vesting of Account. Each Participant shall be vested in the amounts credited to such
Participant’s Account and earnings thereon as follows: 
  

	 	(a)	Amounts Deferred. A Participant shall be 100% vested at all times in the amount of Compensation elected to be deferred under the Plan, and earnings thereon.

  

	 	(b)	Discretionary Contributions. A Participant’s Discretionary Contributions, and earnings thereon, shall become vested as determined by the ONC Committee.

  

	 	(c)	Transferred Account. A Participant shall be 100% vested at all times in the balance of his Transferred Bay State Account or Transferred Columbia Account, if any.

 5.6 Statement of Account. The Retirement Committee shall give to each Participant a statement
showing the balance in the Participant’s Account periodically, at such times as may be determined by the Retirement Committee, in written or electronic form. 
 ARTICLE VI 
 INVESTMENTS 

6.1 Investment Options. Amounts credited hereunder to the Account of a Participant shall be invested as such Participant
elects among the investment choices provided to the Participant. The investment options shall be determined by the Company from time to time in its sole and absolute discretion. No election of a Deferral Commitment by a Participant shall be
effective until such time as the Participant submits his initial investment election to the Company. Such investment election shall continue to apply to subsequent Deferral Commitments made by the Participant until changed by the Participant.

  
 7 

 6.2 Special Investment Option for Former Participants in the Bay State Plan and
Participants in the Plan. Former participants in the Bay State Plan who became Participants in the Plan, or Participants in the Plan on November 1, 2000, shall have an additional special investment option applicable solely to their
Transferred Bay State Account balances, or their Account balances in the Plan, valued as of November 1, 2000, and any subsequent amounts contributed to such Participant’s Account. Such Participants may invest their Transferred Bay State
Account balances, or their Account balances in the Plan as of November 1, 2000, and any subsequent amounts contributed to such Participant’s Account, in a subaccount which shall be credited with earnings equal to one percentage point
higher than the effective annual yield of the average of the Moody’s Average Corporate Bond Yield Index for the previous calendar month as published by Moody’s Investor Services, Inc. (or any successor publisher thereto), or, if such index
is no longer published, a substantially similar index selected by the Plan Administrator. A Participant’s Transferred Bay State Account balance, or his Account balance in the Plan on November 1, 2000, shall be invested pursuant to this
special investment option from and after November 1, 2000, and until such time as another investment choice is designated by him pursuant to Section 6.1 with respect to all or a portion of his Transferred Bay State Account, or his Account
balance in the Plan on November 1, 2000. Subsequent amounts contributed to any such Participant’s Account may be invested pursuant to this option as designated by the Participant pursuant to Section 6.1. However, any portion of a
Transferred Bay State Account, or an Account balance in the Plan, subsequently transferred from the investment option described in this Section 6.2 to another investment option may not be reinvested under this Section 6.2. 

6.3 Special Investment Option for Former Participants in the Columbia Plan. Former participants in the Columbia Plan who
become Participants in the Plan on January 1, 2004 shall have an additional special investment option applicable solely to their Transferred Columbia Account balances, valued as of January 1, 2004, Such Participants may invest all or any
portion of their Transferred Columbia Account balances in a subaccount that shall be credited each day with earnings equal to the prime rate of interest in effect as of such business day, as listed in The Wall Street Journal. All or the designated
portion of a Participant’s Transferred Columbia Account balance shall be invested pursuant to this special investment option from and after January 1, 2004, and until such time as another investment choice is designated by him pursuant to
Section 6.1 with respect to all or a portion of his Transferred Columbia Account. Any portion of a Transferred Columbia Account subsequently transferred from the investment option described in this Section 6.3 to another investment option
may not be reinvested under the investment option described in this Section 6.3. Amounts contributed to any such Participant’s Account on or after January 1, 2004 shall not be eligible for the investment option described in this
Section 6.3.

 ARTICLE VII 

PAYMENTS AND DISTRIBUTIONS 
 7.1 Distributions/Events Generally. Participants generally will not be entitled to receive a distribution of their Account balance until they separate from service with the Employer for any
reason, as provided in Section 7.3. A Participant may receive a distribution before separation from service, however, in accordance with this Article VII, upon (1) an Unforeseeable Emergency that occurs before separation from service, or
(2) a year that has been designated by the Participant in a Deferral Commitment and that occurs before separation from service. 
 7.2 In-Service Distributions. 
  

	 	(a)	General Payments. A Participant, in connection with a Deferral Commitment, may elect to receive his or her Compensation deferred for a Deferral Period, and all
amounts credited or debited thereto, in a specified year while employed with an Employer. The Participant, in a Deferral Commitment, may elect to receive such an in-service distribution as either a lump sum or equal annual installments over a period
of not more than 15 years. If a Participant does not make such an election, the payment shall be made in a lump sum. 

 If a Participant elects to receive an in-service distribution as a lump sum, the amount of the lump sum payment will be based on the value of the Participant’s account as of March 15 of the
designated year. The distribution date generally shall be March 31 of such year, or, if later, within such time frame permitted under Code Section 409A and the guidance and regulations thereunder. 

If a Participant elects to receive installments, the amount of each installment payment will be based on the value of the
participant’s account as of the March 15 preceding the distribution of each installment payment. The distribution date generally shall be each subsequent March 31, or if later, within such time frame permitted under Code
Section 409A, and the guidance and regulations thereunder. 
  

	 	(b)	Modifying In-Service Distributions. 

 (1) Pre-2005 Account. Notwithstanding any other provision of the Plan, a Participant may modify his election as to the form or time of distribution of his entire Pre-2005 Account, and earnings
thereon, by a writing filed with the Retirement Committee at any time prior to the commencement of payment. A Participant’s modification of his election as to the form or time of commencement of payment shall be ineffective, unless (1) the
modification election is filed with the Retirement Committee more than 12 months prior to the time of commencement of payment, or (2) a Participant elects by written instrument delivered to the Company prior to the time of commencement of
payment to have his Pre-2005 Account reduced by 10%. This reduction shall be forfeited and used by the Plan to reduce expenses of administration. This reduction is intended to discourage a Participant from modifying his election as to the form or
time of commencement of payment within the period set forth in clause (1) above and prevent him from being deemed in constructive receipt of his Pre-2005 Account prior to its actual payment to him. 

  
 9 

 (2) Post-2004 Account. The Company, in its discretion, may allow a
Participant to modify his election as to the form or time of distribution of his entire Post-2004 Account, and earnings thereon, or of any Post-2004 Deferral Commitment under the Plan and earnings thereon, if (1) such election does not take
effect until at least 12 months after the date on which the election is made, (2) the first payment with respect to which such election is made is deferred for a period of not less than five (5) years from the date on which such payment
would otherwise have been made, and (3) any election related to a payment to be made at a specified date is made at least 12 months prior to the date of the first scheduled payment. For purposes of the Plan, the term “payment” means
each separate installment and not the collective group of installment payments. 
  

	 	(c)	Precedence of Distributions. In the event a Participant has a separation from service, Severe Financial Hardship, or other event that triggers distribution of
benefits under Article VII of this Plan, all amounts subject to an in-service distribution shall be paid in accordance with other applicable provisions of the Plan and not under this Section 7.2. If, however, a Participant made an election to
postpone an in-service distribution under Section 7.2(b), and the Participant separates from service, the distribution will be made in accordance with Section 7.2(b) and not Section 7.3. 

7.3 Distributions After Separation from Service. 

 

	 	(a)	Generally. If a Participant separates from service with an Employer, the provisions of this Section 7.3 shall apply to the distribution of the
Participant’s account. The Participant may elect, in his or her, Deferral Commitment, to receive such benefits as either a lump sum or in equal annual installments over a period not to exceed 15 years. If no such election is made, payment shall
be made as a lump sum. 

  

	 	(b)	Lump Sum. 

 (1) Pre-2005 Account. If payment of a Participant’s Pre-2005 Account is to be made in a lump sum, the lump sum payment generally shall be made on or as soon as administratively practicable
after the March 31st immediately after the date in
which the Participant separates from service. 
 (2) Post-2004 Account. 

(a) Non-Specified Employees. If payment of a Participant’s Post-2004 Account is to be
made to the Participant in a lump sum, and the Participant is not a Specified Employee of any Employer as defined in Section 7.3(d) of this Plan and consistent with the guidance under Code Section 409A, the lump sum payment generally shall
be made on or as soon as administratively practicable after the March 31st immediately after the date in which the Participant separates from service. 

  
 10 

 (b) Specified Employees. If payment of a
Participant’s Post-2004 Account is to be made to the Participant in a lump sum, and the Participant is a Specified Employee of any Employer, as defined in Section 7.3(d) of this Plan and consistent with the guidance under Code
Section 409A, the lump sum payment generally shall be made on or as soon as administratively practicable after the later of (1) the March 31st immediately after the date in which the Participant separates from service, or (2) the date that is six
(6) months after the date in which the Participant separates from service, unless due to such Participant’s death, in which case payment generally shall be made to the Beneficiary as soon as practicable after the date of the
Participant’s death. 
  

	 	(c)	Installments. 

 (1) Pre-2005 Account. If payment of a Participant’s Pre-2005 Account is to be made in annual installments, the distribution of the first annual installment payment generally shall be made on
or as soon as administratively practicable after the March 31st immediately after the date in which the Participant separates from service. The amount of this first installment payment shall be based on the value of the Participant’s Account as of the
March 15 preceding the distribution date of this installment payment. Each subsequent installment payment generally shall be paid on or as soon as administratively practicable after each subsequent March 31. The amount of each such
installment shall be based on the value of the Participant’s account as of the March 15 preceding the distribution date of such installment. 
 (2) Post-2004 Account. 
 (a)
Non-Specified Employees. If payment of a Participant’s Post-2004 Account is to be made to the Participant in annual installments, the distribution of the first annual installment payment generally shall be made on or as soon as
administratively practicable after the March 31st
immediately after the date in which the Participant separates from service. The amount of this first installment payment shall be based on the value of the Participant’s Account as of the March 15 preceding the distribution date of this
installment payment. Each subsequent installment payment generally shall be paid on or as soon as administratively practicable after each subsequent March 31. The amount of each such installment shall be based on the value of the
Participant’s account as of the March 15 preceding the distribution date of such installment. 
 (b)
Specified Employees. If payment of a Participant’s Post- 2004 Account is to be made to the Participant in annual installments, and the Participant is a Specified Employee of any Employer, as defined in Section 7.3(d) of this Plan
and consistent with the guidance under Code Section 409A, the distribution of the first annual installment payment generally shall be made on or as soon as administratively practicable after

  
 11 

 
the later of (1) the March 31st immediately after the date in which the Participant separates from service, or (2) the date that is six (6) months after the date in which the Participant separates from service, unless due to
such Participant’s death, in which case such installment payment generally shall be made to the Beneficiary as soon as practicable after the date of the Participant’s death. The amount of this first installment payment shall be based on
the value of the Participant’s Account as of the March 15 preceding the distribution date of this installment payment. Each subsequent installment payment generally shall be paid on or as soon as administratively practicable after each
subsequent March 31. The amount of each such installment shall be based on the value of the Participant’s account as of the March 15 preceding the distribution date of such installment. 

 

	 	(d)	Specified Employee Determination. A Participant shall be deemed to be a Specified Employee for purposes of this Section 7.3 if he or she is in job scope
level C2 or above with respect to any Employer that employees him; provided that if at any time the total number of Employees in job category C2 and above is less than 50, a Specified Employee shall include any employee who meets the definition of
Key Employee set forth in Code Section 416(i) without reference to paragraph (5). A Participant shall be deemed to be a Specified Employee with respect to a calendar year if he or she is a Specified Employee on September 30 of the
preceding calendar. 

  

	 	(e)	Modifying Separation from Service Distributions. 

 (i) Pre-2005 Account. Notwithstanding any other provision of the Plan, a Participant may modify his election as to the form or time of distribution of his entire Pre-2005 Account, and earnings
thereon, by a writing filed with the Retirement Committee at any time prior to the commencement of payment. A Participant’s modification of his election as to the form or time of commencement of payment shall be ineffective, unless (1) the
modification election is filed with the Retirement Committee more than 12 months prior to the time of commencement of payment, or (2) a Participant elects by written instrument delivered to the Company prior to the time of commencement of
payment to have his Pre-2005 Account reduced by 10%. This reduction shall be forfeited and used by the Plan to reduce expenses of administration. This reduction is intended to discourage a Participant from modifying his election as to the form or
time of commencement of payment within the period set forth in clause (1) above and prevent him from being deemed in constructive receipt of his Pre-2005 Account prior to its actual payment to him. 

(ii) Post-2004 Account. The Company, in its discretion, may allow a Participant to modify his election as to the
form or time of distribution of his entire Post-2004 Account, and earnings thereon, or of any Post-2004 Deferral Commitment under the Plan and earnings thereon, if (1) such election does not take effect until at least 12 months after the date
on which the election is made, 

  
 12 

 
(2) the first payment with respect to which such election is made is deferred for a period of not less than five (5) years from the date on which such payment would otherwise have been made,
and (3) any election related to a payment to be made at a specified date is made at least 12 months prior to the date of the first scheduled payment. For purposes of the Plan, the term “payment” means each separate installment and not
the collective group of installment payments. 
 7.4 Unforeseeable Emergency/Hardship Distributions. 

 

	 	(a)	Upon a finding that a Participant has suffered an Unforeseeable Emergency, the Retirement Committee may, in its sole discretion, make distributions from the
Participant’s Pre-2005 Account (including his Transferred Bay State Account or Transferred Columbia Account, if applicable). The amount of such a distribution shall be limited to the amount reasonably necessary to meet the Participant’s
needs resulting from the Unforeseeable Emergency. Any distribution pursuant to this Section 7.4(a) shall be payable in a lump sum. The distribution shall be paid within 30 days after the determination of an Unforeseeable Emergency.

  

	 	(b)	Upon a finding that a Participant has suffered an Unforeseeable Emergency, the Retirement Committee may, in its sole discretion, make distributions from the
Participant’s Post-2004 Account and/or allow a Participant to suspend his Deferred Commitment entirely. The amount of such distribution shall be limited to the amount necessary to satisfy such Unforeseeable Emergency plus amounts necessary to
pay taxes reasonably anticipated as a result of the distribution, after taking into account the extent to which such hardship is or may be relieved through reimbursement or compensation by insurance or otherwise or by liquidation of the
Participant’s assets (to the extent the liquidation of such assets would not itself cause severe financial hardship). Any distribution pursuant to this Section 7.4(b) shall be payable in a lump sum. The distribution shall be paid within 30
days after the determination of an Unforeseeable Emergency. 

 7.5 Distribution Provisions Applicable to a
Transferred Bay State Account. Notwithstanding any other provision in the Plan, the following provisions shall apply to the form and time of payment of the balance of a Transferred Bay State Account: 

 

	 	(a)	The portion of a Transferred Bay State Account not paid pursuant to Section 7.2 shall be paid to a Participant following his separation from service, or to his
Beneficiary in the case of death, in the form selected by the Participant, by written instrument delivered to the Retirement Committee before November 1, 2000. If no form is selected by the Participant, payment shall be made in a lump sum. The
provisions of Section 7.2(b) shall apply with respect to the election of the form of payment of a Transferred Bay State Account and the modification of such election. 

 

	 	(b)	 Any former employee of Bay State Gas Company who (1) was a participant in the Bay State Plan immediately prior to November 1, 2000,
(2) terminated employment with Bay State Gas Company prior to November 1, 2000, for any 

  
 13 

	 	
reason other than Retirement, death or Disability (as such terms were defined in the Bay State Plan immediately prior to November 1, 2000), and (3) as of November 1, 2000, had not
commenced payment of his Account shall not commence payment of his Transferred Bay State Account until the earlier of the Participant’s attainment of age 65, Disability or death. Notwithstanding the preceding sentence, the Retirement Committee
may, in its sole discretion, vary the manner and time of making the payment of a Participant’s Transferred Bay State Account to such former Bay State employee, and may make such distributions over a longer or shorter period of time or in a lump
sum. 

 7.6 Automatic Cash-Out. In the event a Participant’s Account balance at the time
distribution begins, or following a distribution of an installment payment is $15,000 or less, that balance shall be paid to the Participant or his Beneficiary in a lump sum on the next annual installment distribution date notwithstanding any form
of benefit payment elected by the Participant. 
 7.7 Special Payment Election by December 31, 2006, for Code
Section 409A Transition Relief. Notwithstanding any other provision of this Plan, a Participant may change an election with respect to the time and form of payment of Post-2004 Benefit, without regard to the restrictions imposed under
paragraph (i) next above, on or before December 31, 2006; provided that such election (1) applies only to amounts that would not otherwise be payable in calendar year 2006, and (2) shall not cause an amount to be paid in calendar
year 2006 that would not otherwise be payable in such year. 
 7.8 Withholding for
Taxes. To the extent required by the law in effect at the time payments are made, an Employer shall withhold from the payments made hereunder any taxes required to be withheld by the federal or any state or local
government, including any amounts which the Employer determines is reasonably necessary to pay any generation-skipping transfer tax which is or may become due. A Beneficiary, however, may elect not to have withholding of federal income tax pursuant
to Code Section 3405(a)(2). 
 7.9 Payment to Guardian. The Retirement Committee may direct payment to the duly
appointed guardian, conservator or other similar legal representative of a Participant or Beneficiary to whom payment is due. In the absence of such a legal representative, the Retirement Committee may, in its sole and absolute discretion, make
payment to a person having the care and custody of a minor, incompetent or person incapable of handling the disposition of property upon proof satisfactory to the Retirement Committee of incompetency, status as a minor, or incapacity. Such
distribution shall completely discharge the Company from all liability with respect to such benefit.

 ARTICLE VIII 

BENEFICIARY DESIGNATION 
 8.1 Beneficiary Designation. Subject to Section 8.3, each Participant shall have the right, at any time, to designate one or more persons or an entity as Beneficiary (both primary as
well as secondary) to whom benefits under the Plan shall be paid in the event of the Participant’s death prior to complete distribution of the Participant’s Account, Each Beneficiary designation shall be in a written form prescribed by the
Retirement Committee and shall be effective only when filed with the Retirement Committee during the Participant’s lifetime. 
 8.2 Changing Beneficiary. Subject to Section 8.3, any Beneficiary designation may be changed by a Participant without the consent of the previously named Beneficiary by the filing of a
new designation with the Retirement Committee. The filing of a new designation shall cancel all designations previously filed. 

8.3 Community Property. If the Participant resides in a community property state, the following rules shall apply:

  

	 	(a)	Designation by a married Participant of a Beneficiary other than the Participant’s spouse shall not be effective unless the spouse executes a written consent that
acknowledges the effect of the designation, or it is established that the consent cannot be obtained because the spouse cannot be located. 

  

	 	(b)	A married Participant’s Beneficiary designation may be changed by a Participant with the consent of the Participant’s spouse as provided for in
Section 8.3(a) by the filing of a new designation with the Retirement Committee. 

  

	 	(c)	If the Participant’s marital status changes after the Participant has designated a Beneficiary, the following shall apply: 

(i) If the Participant is married at the time of death but was unmarried when the designation was made, the designation
shall be void unless the spouse has consented to it in the manner prescribed in Section 8.3(a). 
 (ii) If
the Participant is unmarried at the time of death but was married when the designation was made: 
 (A) The
designation shall be void if the spouse was named as Beneficiary, unless the designation is reaffirmed when the Participant is unmarried. 
 (B) The designation shall remain valid if a nonspouse Beneficiary was named. 

  
 15 

 (iii) If the Participant was married when the designation was made and is
married to a different spouse at death, the designation shall be void unless the new spouse has consented to it in the manner prescribed above. 
 8.4 No Beneficiary Designation. If any Participant fails to designate a Beneficiary in the manner provided above, if the designation is void or if the Beneficiary designated by a deceased
Participant dies before the Participant or before complete distribution of the Participant’s benefits, the Participant’s Beneficiary shall be the person in the first of the following classes in which there is a survivor: 

 

	 	(a)	The Participant’s spouse; 

  

	 	(b)	The Participant’s children in equal shares, except that if any of the children predeceases the Participant but leaves issue surviving, then such issue shall take,
by right of representation, the share the parent would have taken if living; 

  

	 	(c)	The Participant’s estate. 

ARTICLE IX 
 PLAN ADMINISTRATION 
 9.1 Allocation of Duties to
Committees. The Plan shall be administered by the Benefits Committee, as delegated by the ONC Committee. The Benefits Committee shall have the authority to make, amend, interpret, and enforce all appropriate rules and regulations for the
administration of the Plan and decide or resolve any and all questions, including interpretations of the Plan, as may arise in such administration, except as otherwise reserved to the ONC Committee herein, or by resolution or charter of the
respective committees. Members of the Retirement Committee or Benefits Committee may be Participants under the Plan. 
 In its
discretion, the Plan Administrator may delegate to any division or department of the Company the discretionary authority to make decisions regarding Plan administration, within limits and guidelines from time to time established by the Plan
Administrator. The delegated discretionary authority shall be exercised by such division or department’s senior officer, or his/her delegate. Within the scope of the delegated discretionary authority, such officer or person shall act in the
place of the Plan Administrator and his/her decisions shall be treated as decisions of the Plan Administrator. 
 Specifically,
the Plan Administrator hereby delegates certain of its discretionary authority with respect to the Plan to the Retirement Committee. Pursuant to the foregoing sentence, the delegation by the Plan Administrator to the Retirement Committee includes,
but shall not be limited to, the ability to solicit and receive deferral elections, establish enrollment periods, distribute account statements, receive distribution elections and any permitted modifications thereto, make distributions, and
determine claims under the Plan. 

  
 16 

 9.2 Agents. The Retirement Committee, Benefits Committee or ONC Committee may,
from time to time, employ agents and delegate to them such administrative duties as it sees fit, and may from time to time consult with counsel who may be counsel to the Company. 

9.3 Binding Effect of Decisions. The decision or action of the Retirement Committee, Benefits Committee and/or the ONC
Committee (or any duly authorized delegate of any such committee) with respect to any question arising out of or in connection with the administration, interpretation and application of the Plan and the rules and regulations promulgated hereunder
shall be final, conclusive and binding upon all persons having any interest in the Plan. 
 9.4 Section 16
Compliance. 
  

	 	(a)	In General. This Plan is intended to be a formula plan for purposes of Section 16 of the Securities Exchange Act (the “Act”). Accordingly, in the
case of a deferral or other action under the Plan that constitutes a transaction that could be covered by Rule 16b-3(d) or (e), if it were approved by the ONC Committee (“Board Approval”), it is intended that the Plan shall be administered
by delegates of the Board, in the case of a Participant who is subject to Section 16 of the Act, in a manner that will permit the Board Approval of the Plan to avoid any additional Board Approval of specific transactions to the maximum possible
extent. 

  

	 	(b)	Approval of Distributions: This Subsection shall govern the distribution of a deferral that (i) is being distributed to a Participant in cash, (ii) is made to
a Participant who is subject to Section 16 of the Act at the time the interest in phantom Company Common Stock, if any, would be liquidated in connection with the distribution, and (iii) if paid at the time the distribution would be made
without regard to this subsection, could result in a violation of Section 16 of the Act because there is an opposite way transaction that would be matched with the liquidation of the Participant’s interest in phantom Company Common Stock
(either as a “discretionary transaction,” within the meaning of Rule 16b-3(b)(l), or as a regular transaction, as applicable) (“Covered Distribution”). In the case of a Covered Distribution, if the liquidation of the
Participant’s interest in the phantom Company Common Stock in connection with the distribution has not received Board Approval by the time the distribution would be made if it were not a Covered Distribution, or if it is a discretionary
transaction, then the actual distribution to the Participant shall be delayed only until the earlier of: 

 (1) In the case of a transaction that is not a discretionary transaction, Board Approval of the liquidation of the Participant’s interest in the phantom Company Common Stock in connection with the
distribution, or 
 (2) The date the distribution would no longer violate Section 16 of the
Act, e.g., when the Participant is no longer subject to Section 16 of the Act, or when the time between the liquidation and an opposite way transaction is sufficient. 

  
 17 

 ARTICLE X 

CLAIMS PROCEDURE 
 10.1 Claim. Claims for benefits under the Plan shall be made in writing to the Retirement Committee. The Retirement Committee shall establish rules and procedures to be followed by
Participants and Beneficiaries in filing claims for benefits, and for furnishing and verifying proof necessary to establish the right to benefits in accordance with the Plan, consistent with the remainder of this Article. 

10.2 Review of Claim. The Retirement Committee shall review all claims for benefits. Upon receipt by the Retirement
Committee of such a claim, it shall determine all facts that are necessary to establish the right of the claimant to benefits under the provisions of the Plan and the amount thereof as herein provided within 90 days of receipt of such claim. If
prior to the expiration of the initial 90 day period, the Retirement Committee determines additional time is needed to come to a determination on the claim, the Retirement Committee shall provide written notice to the Participant, Beneficiary or
other claimant of the need for the extension, not to exceed a total of 180 days from the date the application was received. If the Retirement Committee fails to notify the claimant in writing of the denial of the claim within 90 days after the
Retirement Committee receives it, the claim shall be deemed denied. 
 10.3 Notice of Denial of Claim. If the
Retirement Committee wholly or partially denies a claim for benefits, the Retirement Committee shall, within a reasonable period of time, but no later than 90 days after receiving the claim (unless extended as provided above), notify the claimant in
writing of the denial of the claim. Such notification shall be written in a manner reasonably expected to be understood by such claimant and shall in all respects comply with the requirements of ERISA, including but not limited to inclusion of the
following; 
  

	 	(a)	the specific reason or reasons for denial of the claim; 

  

	 	(b)	a specific reference to the pertinent sections of the Plan on which the denial is based; 

 

	 	(c)	a description of any additional material or information necessary for the claimant to perfect the claim and an explanation of why such material or information is
necessary; and, where appropriate, 

  

	 	(d)	an explanation of the Plan’s review procedures. 

 10.4 Reconsideration of Denied Claim. Within 60 days after receipt of the notice of the denial of a claim or within 60 days after the claim is deemed denied as set forth above, if
applicable, such claimant or duly authorized representative may request, by mailing or delivery of such written notice to the Benefits Committee, a reconsideration by the Benefits Committee of the decision denying the claim. If the claimant or duly
authorized representative fails to request such a reconsideration within such 60 day period, it shall be conclusively determined for all purposes of the Plan that the denial of such claim by the Benefits Committee is correct. In connection with the
claimant’s appeal of the denial of his or her benefit, the claimant may review pertinent documents and may submit issues and comments in writing. 

  
 18 

 After such reconsideration request, the Benefits Committee shall determine within 60 days of
receipt of the claimant’s request for reconsideration whether such denial of the claim was correct and shall notify such claimant in writing of its determination. In the event of special circumstances determined by the Benefits Committee, the
time for the Benefits Committee to make a decision may be extended by an additional 60 days upon written notice to the claimant prior to the commencement of the extension. The notice of decision shall be in writing and shall include specific reasons
for the decision, written in a manner calculated to be understood by the claimant, as well as specific references to the pertinent Plan provisions on which the decision is based. If the decision on review is not furnished within the time period set
forth above, the claim shall be deemed denied on review. 
 If such determination is favorable to the claimant, it shall be
binding and conclusive. If such determination is adverse to such claimant, it shall be binding and conclusive unless the claimant or his duly authorized representative notifies the Benefits Committee within 90 days after the mailing or delivery to
the claimant by the Benefits Committee of its determination that claimant intends to institute legal proceedings challenging the determination of the Benefits Committee and actually institutes such legal proceedings within 180 days after such
mailing or delivery. 
 10.5 Employer to Supply Information. To enable the Retirement Committee or the Benefits
Committee to perform its functions, each Employer shall supply full and timely information to the respective committee of all matters relating to the retirement, death or other cause for separation from service of all Participants, and such other
pertinent facts as the respective committee may require. 
 ARTICLE XI 

AMENDMENT AND TERMINATION OF PLAN 
 11.1 Plan Amendment. The ONC Committee or the Board shall have the authority to amend the Plan. The ONC Committee or the Board shall have the exclusive authority to amend the Plan regarding
eligibility for the Plan, the amount or level of benefits awarded under the Plan, and the time and form of payments for benefits from the Plan. In addition, the ONC Committee or the Board shall also have the exclusive authority to make amendments
that constitute a material increase in compensation, any change requiring action or consent by a committee of the Board pursuant to the rules of the Securities and Exchange Commission, the New York Stock Exchange or other applicable law, or such
other material changes to the Plan such that approval of the Board is required. Unless otherwise determined by the ONC Committee, the Benefits Committee shall have the authority to amend the Plan in all respects that are not exclusively reserved to
the ONC Committee or the Board. 
 The respective committee may at any time amend the Plan by written instrument, notice of
which is given to all Participants, and to Beneficiaries receiving installment payments. 

  
 19 

 Notwithstanding the preceding sentence, no amendment shall reduce the amount accrued in any Account prior to
the date such notice of the amendment is given. 
 11.2 Plan Termination. The ONC Committee or the Company may at
any time partially or completely terminate the Plan if, in its judgment, the tax, accounting or other effects of the continuance of the Plan, or potential payments thereunder, would not be in the best interests of the Employers. 

 

	 	(a)	Partial Termination. The ONC Committee may partially terminate the Plan by instructing the Retirement Committee not to accept any additional Deferral
Commitments. If such a partial termination occurs, the Plan shall continue to operate and be effective with regard to Deferral Commitments entered into prior to the effective date of such partial termination. 

 

	 	(b)	Complete Termination. The ONC Committee may completely terminate the Plan by instructing the Retirement Committee not to accept any additional Deferral
Commitments, and by terminating all ongoing Deferral Commitments. If such a complete termination occurs, the Plan shall cease to operate and the Employers shall pay out each Pre-2005 Account in equal monthly installments over the following period,
based on the Pre-2005 Account balance: 

  

			
	 Account Balance
	  	Payout Period
	 Less than $50,000
	  	Lump Sum
	 $50,000 but less than $100,000
	  	3 Years
	 More than $100,000
	  	5 Years

 Payments shall commence within 65 days after the ONC Committee terminates the Plan, and earnings shall continue to be
credited on the unpaid Account balance. Employers shall pay out each Post-2004 Account in the manner and at the time described in Articles IV and VII. 
 ARTICLE XII 
 MISCELLANEOUS 

12.1 Unfunded Plan. The Plan is an unfunded plan maintained primarily to provide deferred compensation benefits for a
select group of “management or highly-compensated employees” within the meaning of Sections 201, 301 and 401 of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), and therefore is exempt from the
provisions of Parts 2, 3 and 4 of Title I of ERISA. 
 12.2 Company and Employer Obligations. The obligation to
make benefit payments to any Participant under the Plan shall be a joint and several liability of the Company and the Employer that employed the Participant. 

  
 20 

 12.3 Unsecured General Creditor. Participants and Beneficiaries shall be
unsecured general creditors, with no secured or preferential right to any assets of the Employer or any other party for payment of benefits under the Plan. Any life insurance policies, annuity contracts or other property purchased by the Employer in
connection with the Plan shall remain its general, unpledged and unrestricted assets. The Employer’s obligation under the Plan shall be an unfunded and unsecured promise to pay money in the future. 

12.4 Trust Fund. Subject to Section 12.3, the Company may establish separate subtrusts for deferrals by employees of
each Employer, pursuant to a trust agreement entered into with such trustees as the Benefits Committee may approve, for the purpose of providing for the payment of benefits owed under the Plan. At its discretion, each Employer may contribute
deferrals under the Plan for its employees to the subtrust established with respect to such Employer under such trust agreement. To the extent any benefits provided under the Plan are paid from any such subtrust, the Employer shall have no further
obligation to pay them. If not paid from a subtrust, such benefits shall remain the obligation of the Employer. Although such subtrusts may be irrevocable, their assets shall be held for payment of all the Company’s general creditors in the
event of insolvency or bankruptcy. 
 12.5 Nonalienation/Nonassignability. Neither a Participant nor any
other person shall have any right to commute, sell, assign, transfer, pledge, anticipate, mortgage, or otherwise encumber, transfer, hypothecate, or convey in advance of actual receipt the amounts, if any, payable hereunder, or any part thereof or
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. 

Notwithstanding the preceding paragraph, the Account of any Participant shall be subject to and payable in the amount determined in
accordance with any qualified domestic relations order, as that term is defined in Section 206(d)(3) of ERISA. The Retirement Committee shall provide for payment in a lump sum from a Participant’s Account to an alternate payee (as defined
in Code Section 414(p)(8)) as soon as administratively practicable following receipt of such order. Any federal, state or local income tax associated with such payment shall be the responsibility of the alternate payee. The balance of an
Account that is subject to any qualified domestic relations order shall be reduced by the amount of any payment made pursuant to such order. 
 12.6 Indemnification. 
  

	 	(a)	Limitation of Liability. Notwithstanding any other provision of the Plan or the Trust, none of the Company, any member of the Retirement Committee, the Benefits

Participant, for any claim, loss, liability or expense incurred in connection with the Plan or the Trust, except when the same shall have been judicially determined to be due to the willful misconduct of such person. 

  
 21 

	 	(b)	Indemnity. The Company shall indemnify and hold harmless each member of the Retirement Committee, the Benefits Committee and the ONC Committee, or any employee
of the Company or any individual acting as an employee or agent of either of them (to the extent not indemnified or saved harmless under any liability insurance or any other indemnification arrangement with respect to the Plan or the Trust) from any
and all claims, losses, liabilities, costs and expenses (including attorneys’ fees) arising out of any actual or alleged act or failure to act made in good faith pursuant to the provisions of the Plan, including expenses reasonably incurred in
the defense of any claim relating thereto with respect to the administration of the Plan or the Trust, except that no indemnification or defense shall be provided to any person with respect to any conduct that has been judicially determined, or
agreed by the parties, to have constituted willful misconduct on the part of such person, or to have resulted in his or her receipt of personal profit or advantage to which he or she is not entitled. In connection with the indemnification provided
by the preceding sentence, expenses incurred in defending a civil or criminal action, suit or proceeding, or incurred in connection with a civil or criminal investigation, may be paid by the Company in advance of the final disposition of such
action, suit, proceeding, or investigation, as authorized by the Retirement Committee, the Benefits Committee or the ONC Committee in the specific case, upon receipt of an undertaking by or on behalf of the party to be indemnified to repay such
amount unless it shall ultimately be determined that the person is entitled to be indemnified by the Company pursuant to this paragraph. 

 12.7 Not a Contract of Employment. The Plan shall not constitute a contract of employment between an Employer and the Participant. Nothing in the Plan shall give a Participant the right to
be retained in the service of an Employer or to interfere with the right of an Employer to discipline or discharge a Participant at any time. 
 12.8 Protective Provisions. A Participant shall cooperate with his Employer by furnishing any and all information requested by the Employer in order to facilitate the payment of benefits

12.10 Validity. In case any provision of the Plan shall be held illegal or invalid for any reason, said illegality or
invalidity shall not affect the remaining parts hereof, but the Plan shall be construed and enforced as if such illegal and invalid provision had never been inserted herein.

Tax Savings Clause. Notwithstanding anything to the contrary contained in the Plan, (1) in the event that the Internal Revenue Service prevails in its claim that amounts contributed to the Plan for the benefit of a Participant,
and/or earnings thereon, constitute taxable income under Code Section 409A, and guidance and regulations thereunder, to the Participant or his Beneficiary for a taxable year prior to the taxable year in which such contributions and/or earnings
are distributed to him, or (2) in the event that legal counsel satisfactory to the Company, and the applicable Participant or his Beneficiary, renders an opinion that the Internal Revenue Service would likely prevail in such a claim, the
Post-2004 Account, to the extent constituting such taxable income, shall be immediately distributed to the Participant or his Beneficiary. For purposes of this Section, the Internal Revenue Service shall be deemed to have prevailed in a claim if
such claim is upheld by a court of final jurisdiction, or, if based upon an opinion of legal counsel satisfactory to the Company and the Participant or his Beneficiary, the Plan fails to appeal a decision of the Internal Revenue Service, or a court
of applicable jurisdiction, with respect to such claim to an appropriate Internal Revenue Service appeals authority or to a court of higher jurisdiction within the appropriate time period.

 NISOURCE INC. 
 SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN 
 As Amended and Restated Effective
January 1, 2010 
 ARTICLE I 
 Background and Purpose 
 1.1 Background. Northern Indiana
Public Service Company adopted the Northern Indiana Public Service Company Supplemental Executive Retirement Plan effective as of December 23, 1982. The Plan was amended as of January 1, 1989. The Plan was subsequently adopted by NIPSCO
Industries, Inc., the successor to Northern Indiana Public Service Company, effective as of January 1, 1991. The Plan was amended and restated, effective January 1, 1993 and September 1, 1994. Effective June 1, 2002, NiSource
Inc., the parent company of NIPSCO Industries, Inc., assumed sponsorship of the Plan and the Plan was further amended and restated to make administrative and technical changes. The Plan was further amended, effective January 1, 2004, to reflect
changes in the structure of benefits under the Plan. The Plan was again amended and restated, effective January 1, 2005, to comply with Internal Revenue Code Section 409A with respect to benefits earned under the Plan from and after
January 1, 2005. Benefits under the Plan earned and vested prior to January 1, 2005 shall be administered without giving effect to Code Section 409A, and guidance and regulations thereunder. The Plan was again amended and restated,
effective January 1, 2008, to incorporate special transition relief under Internal Revenue Service Notice 2007-86 to allow Participants to elect to change the time and form of payment of certain Post-2004 Benefits. The Plan was further amended
and restated, effective January 1, 2010, to clarify how certain supplemental death benefits will be paid to Participants who have reached Retirement. 
 The Plan is now further amended and restated effective May 13, 2011 to transfer all administrative authority with respect to the Plan (including the authority to render decisions on claims and
appeals and make administrative or ministerial amendments) from the ONC Committee to the Benefits Committee. 
 1.2
Purpose. The purpose of the Plan is to provide selected key executives and employees with additional security in order to aid the Company (as defined herein and including its predecessors) in retaining its present management and, should
circumstances require it, to aid the Company in attracting additions to management. The Company, by providing such additional benefits, expects such key executives and employees to be available for consulting assignments to the Company after
retirement, at the Company’s request. 
 It is intended that the Plan be exempt from the reporting and disclosure
requirements of Title I of the Employee Retirement Income Security Act of 1974 because it is an unfunded plan maintained by an employer for the purpose of providing benefits for a select group of management or highly compensated employees.

	 	(ii)	0.6% of the Participant’s Final Average Compensation multiplied by the Participant’s Service in excess of 30 years. 

  
 6 

	 	(b)	The sum of: 

  

	 	(i)	3% of the Participant’s Final Average Compensation multiplied by the Participant’s Service to a maximum of 20 years; plus 

 

	 	(ii)	0.5% of the Participant’s Final Average Compensation multiplied by the Participant’s Service in excess of 20 years, to a maximum of 30 years; less

  

	 	(iii)	5% of the Participant’s Primary Social Security Benefit, multiplied by the Participant’s Service to a maximum of 20 years. 

After age 65, the Participant shall be eligible for a monthly Supplemental Retirement Pension in accordance with Section 4.2, based
on Service the Participant would have had if the Participant had continued working for the Company or an Affiliate to age 65, the Participant’s Final Average Compensation at the time he or she became Disabled, the Primary Social Security
Benefit determined at the time the Participant became Disabled, and the single-life pension the Participant is entitled to receive at age 65 from the NiSource Pension Plan, or any other Qualified Pension Plan, and the Pension Restoration Plan,
determined at the time he or she became Disabled. 
 4.6 Supplemental Spouse Pension. Upon the death of a Participant in
active employment or while receiving a Supplemental Disability Pension, his or her surviving spouse, if any, shall be eligible to receive a monthly Supplemental Spouse Pension equal to the greater of: 

 

	 	(a)	25% of the Participant’s Final Average Compensation; or 

  

	 	(b)	the monthly amount that would have been payable to such surviving spouse if the Participant had elected payment of his or her monthly Supplemental Retirement Pension in
the form of a reduced 50% joint and survivor Pension, with his or her spouse as the contingent annuitant, terminated employment (on the date of his or her actual death) and then died immediately prior to the commencement of payments.

 The Supplemental Spouse Pension shall commence in the month next following the month of the Participant’s
death and continue for the life of such spouse. In the event that the Supplemental Spouse Pension calculated under option (a) of this Section will provide a greater benefit to the spouse immediately following the Participant’s death, but
option (b) of this Section will provide a greater monthly benefit as of the date the Participant would have attained age 55, the amount of monthly Supplemental Spouse Pension payable to the surviving spouse shall be: (1) calculated and
payable under option (a) during the period immediately following the Participant’s death; and (2) recalculated and payable according to option (b) beginning on the date the Participant would have attained age 55. Beginning on the
earliest date that the surviving spouse could have begun receiving a benefit under the NiSource Pension Plan, or any other Qualified Pension Plan, the Supplemental Spouse Pension payable under this Section shall be reduced by the amount of benefit
under the NiSource Pension Plan, or any other Qualified Pension Plan, and the Pension Restoration Plan that the spouse is (or would have been) entitled to receive. 

  
 7 

 4.7 Retiree Death Benefit. Upon the death of a Participant who has reached Retirement
(including a former Participant who reached Retirement and was paid his or her benefits under this Plan), a lump sum death benefit equal to 50% of his or her retiree group life insurance coverage shall be paid to such Participant’s spouse or
other beneficiaries designated with respect to such coverage. 
 4.8 Cost of Living Adjustment. For Participants in the
FAP Benefit of the NiSource Pension Plan, the benefits payable under Sections 4.2 through 4.7 shall be increased in the same percentage and at the same time as cost of living adjustments are made to the pensions of salaried employees of the Company
or an Affiliate under the NiSource Pension Plan, or any other Qualified Pension Plan. 
 4.9 Separate Agreement.
Notwithstanding prior provisions pertaining to Compensation and Service, each Participant who first becomes eligible to participate in the Plan on and after January 1, 2004 and prior to January 23, 2004 shall have his or her Supplemental
Retirement Pension determined based upon his or her Service and Compensation as set forth in a separate, written agreement, if any, between the Company and such Participant. 
 ARTICLE V

5.1 Applicability. This Article V shall apply to each Participant who first participates the Plan on and after January 23,
2004. 
 5.2 Supplemental Retirement Account. A Participant’s Supplemental Retirement Account is a notional account

or after January 1, 2004 equal to five percent of the Participant’s Compensation for such Plan Year. Supplemental Credits, if any, shall be credited pursuant to Section 5.3. Interest Credits shall be calculated in the same manner and
shall be credited to a Participant’s Supplemental Retirement Account at the same time as provided under the NiSource Pension Plan or any other Qualified Pension Plan. 
 5.3 Supplemental Credits. The ONC Committee, subject to approval of the Board, may authorize Supplemental Credits to a Participant’s Supplemental Retirement Account in such amounts and at such
times, and subject to such specific terms and provisions, as authorized by the ONC Committee.

Supplemental Retirement Account distributed in accordance with Sections 6.1 and 6.2 within 45 days after such separation from Service, or, if later, within such timeframe permitted under Code Section 409A, and guidance and regulations
thereunder. 
 5.5 Death. Upon the death of a Participant prior to final distribution of his or her Supplemental
Retirement Account after completing five or more years of Service, unless a shorter period is provided in a separate, written agreement between the Company and the Participant and approved by the Board, the Participant’s beneficiary, designated

ARTICLE VI 
 Distributions 
 6.1 Pre-2005 Benefit. This Section 6.1
applies only to a Pre-2005 Benefit. 
  

	 	(a)	Form of Payment. Notwithstanding Sections 4.2, 4.3 and 4.4, a Participant shall receive distribution of his or her Pre-2005 Benefit, pursuant to Articles IV or
V, in the same form as his or her distribution under the NiSource Pension Plan, computed in the same manner as in the NiSource Pension Plan, or under any other Qualified Pension Plan, computed in the same manner as in such Qualified Pension Plan.
Any election under the NiSource Pension Plan or any other Qualified Pension Plan shall apply to his or her Pre-2005 Benefit pursuant to the preceding sentence only if it is made by written instrument delivered to the Plan Administrator at least 30
days prior to the date of such distribution. If such election is not so made at least 30 days prior to the date of distribution of his or her Pre-2005 Benefit, the Participant’s Pre-2005 Benefit shall be paid as a 50% joint and survivor Pension
if such Participant is married, or as a single-life Pension if such Participant is unmarried. If a Participant who makes an election pursuant to this subsection 6.1(a) at least 30 days prior to the date of distribution dies prior to
distribution pursuant to such election, such election shall be revoked and the provisions of Article IV and subsection 6.1(b) shall apply. 

  

	 	(b)	Small Benefit Amounts. At the discretion of the Plan Administrator, the present value of any Pre-2005 Benefit payable under the Plan that does not exceed $5,000
may be paid to the Participant or his or her surviving spouse or other designated beneficiary in quarterly, semi-annual or annual installments, or in a single lump sum. 

 

	 	6.2	Post-2004 Benefit. This Section 6.2 applies only to a Post-2004 Benefit. 

  
 9 

	 	(a)	Form of Payment, The Post-2004 Benefit shall be payable in a form available under the NiSource Pension Plan, computed in the same manner as in the NiSource
Pension Plan, or under any other Qualified Pension Plan, computed in the same manner as in such Qualified Pension Plan, as elected by a Participant by written notice delivered to the Plan Administrator on or before December 31, 2005.
Notwithstanding the preceding sentence, in the case of an employee who first becomes a Participant on or after January 1, 2005, the aforementioned election with respect to a Post-2004 Benefit shall be made by written notice delivered to the
Plan Administrator within 30 days after the date the Participant first becomes eligible to participate in the Plan and such election shall be effective with respect to Compensation related to services to be performed subsequent to the election;
provided, however, that a Participant shall not be considered first eligible if, on the date he or she becomes a Participant, he or she participates in any other nonqualified plan of the same category (account balance or nonaccount balance, as
applicable), which is subject to Code Section 409A, maintained by the Company or any Affiliate. If payment in the form of an annuity is elected, the annuity type shall be elected by the Participant at the time he or she makes the election
described in the first or second sentence of this paragraph from among those annuities available at that time under the NiSource Pension Plan or under any other Qualified Pension Plan. If a Participant fails to elect a form of distribution, the
Participant’s Post-2004 Benefit shall be payable in a lump sum. 

 If a Participant who makes an election
pursuant to this subsection 6.2(a) dies prior to distribution pursuant to such election, such election shall be revoked and the provisions of Article IV and subsection 6.2(b) shall apply. 

Any change in an election of a form of distribution available under the NiSource Pension Plan or any other Qualified Pension Plan shall
apply to his or her Post-2004 Benefit pursuant to the preceding paragraph only if it is made by written instrument delivered to the Plan Administrator and if (i) such new election does not take effect until at least 12 months after the date on
which the election is made, (ii) the first payment with respect to which such new election is effective is deferred for a period of not less than five (5) years from the date such payment would otherwise have been made, and (iii) such
new election is not made less than 12 months prior to the date of the first scheduled payment; provided, however, that an election to change from one type of annuity payment to a different, actuarially equivalent, type of annuity payment shall not
be considered a change to the method of payment for purposes of applying the restrictions in clauses (i), (ii) and (iii). 

Notwithstanding the preceding paragraph of this Section 6.2(a), a Participant may change an election with respect to the form of
payment of a Post-2004 Benefit, without regard to the restrictions imposed under the preceding paragraph, on or before December 31, 2006; provided that such election (i) applies only to amounts that would not otherwise be payable in
calendar year 2006, and (ii) shall not cause an amount to be paid in calendar year 2006 that would not otherwise be payable 

  
 10 

 
in such year. Additionally, a Participant may change an election with respect to the form of payment of a Post-2004 Benefit, without regard to the restrictions imposed under the preceding
paragraph, on or before December 31, 2007; provided that such election (i) applies only to amounts that would not otherwise be payable in calendar year 2007, and (ii) shall not cause an amount to be paid in calendar year 2007 that
would not otherwise be paid in such year. Additionally, a Participant may change an election with respect to the form of payment of a Post-2004 Benefit, without regard to the restrictions imposed by the preceding paragraph, on or before

otherwise be paid in such years. 
  

	 	(b)	Specified Employees. Notwithstanding any other provision of the Plan, in no event can a payment of a Post-2004 Benefit, pursuant to Article IV or
Section 5.4, to a Participant who is a Specified Employee of the Company or an Affiliate, at a time during which the Company’s capital stock or capital stock of an Affiliate is publicly traded on an established securities market, in the
calendar year of his or her separation from Service be made before the date that is six months after the date of the Participant’s separation from Service with the Company and all Affiliates, unless such separation is due to his or her death or
Disability. 

 A Participant shall be deemed to be a Specified Employee for purposes of this paragraph (b) if
he or she is in job category C2 or above with respect to the Company or any Affiliate that employs him or her; provided that if at any time the total number of employees in job category C2 and above is less than 50, a Specified Employee shall
include any person who meets the definition of Key Employee set forth in Code Section 416(i) without reference to paragraph (5). A Participant shall be deemed to be a Specified Employee with respect to a calendar year if he or she is a
Specified Employee on September 30th of the preceding calendar year. If a Specified Employee will receive payments hereunder in the form of installments or an annuity, the first payment made as of the date six months after the date of the
Participant’s separation from Service with the Company and all Affiliates shall be a lump sum, paid as soon as practicable after the end of such six-month period, that includes all payments that would otherwise have been made during such
six-month period. From and after the end of such six month period, any such installment or annuity payments shall be made pursuant to the terms of the applicable installment or annuity form of payment.

 ARTICLE VII 

Change in Control 
 7.1 Change in Control. A “Change in Control” shall be deemed to take place on the occurrence of either a “Change in Ownership,” “Change in Effective Control” or a
“Change of Ownership of a Substantial Portion of Assets,” as defined below: 
  

	 	(a)	Change- in Ownership. A Change in Ownership of the Company occurs on the date that any one person, or more than one Person Acting as a Group (as defined below),
acquires ownership of stock of the Company that, together with stock held by such person or group, constitutes more than 50% of the total fair market value or total voting power of the stock of the Company. However, if any one person or more than
one Person Acting as a Group, is considered to own more than 50% of the total fair market value or total voting power of the stock of the Company, the acquisition of additional stock by the same person or persons is not considered to cause a Change
in Ownership of the Company, as applicable (or to cause a Change in Effective Control of the Company). An increase in the percentage of stock owned by any one person, or Persons Acting as a Group, as a result of a transaction in which the Company
acquires its stock in exchange for property’s be treated as an acquisition of stock. This paragraph (a) applies only when there is a transfer of stock of the Company (or issuance of stock of the Company) and stock in the Company remains
outstanding after the transaction. 

  

	 	(b)	Change in Effective Control. A Change in Effective Control of the Company occurs on the date that either 

 

	 	(i)	Any one person, or more than one Person Acting as a Group, acquires (or has acquired during the 12-month period ending on the date of the most recent acquisition by
such person or persons) ownership of stock of the Company possessing 35% or more of the total voting power of the stock of the Company; or 

  

	 	(ii)	a majority of members of the Board is replaced during any 12-month period by directors whose appointment or election is not endorsed by a majority of the members of the
Board prior to the date of the appointment or election, 

 In the absence of an event described in paragraph
(i) or (ii), a Change in Effective Control of the Company will not have occurred. 
 Acquisition of additional
control. If any one person, or more than one Person Acting as a Group, is considered to effectively control the Company, the acquisition of additional control of the Company by the same person or persons is not considered to cause a Change in
Effective Control of the Company (or to cause a Change in Ownership of the Company). 
  

	 	(c)	 Change of Ownership of a Substantial Portion of Assets, A Change of Ownership of a Substantial Portion of Assets occurs on the date that
any one person, or more than one Person Acting as a Group, acquires (or has acquired during the 12-month 

  
 12 

 
period ending on the date of the most recent acquisition by such person or persons) assets from the Company that have a total gross fair market value equal to or more than 40% of the total gross
fair market value of all of the assets of the Company immediately prior to such acquisition or acquisitions. For this purpose, gross fair market value means the value of the assets of the Company, or the value of the assets being disposed of,
determined without regard to any liabilities associated with such assets. 
 Transfers to a related person. There is no
Change in Control when there is a transfer to an entity that is controlled by the shareholders of the Company immediately after the transfer. A transfer of assets by the Company is not treated as a Change of Ownership of a Substantial Portion of
Assets if the assets are transferred to – 
  

	 	(i)	A shareholder of the Company (immediately before the asset transfer) in exchange for or with respect to its stock; 

 

	 	(ii)	An entity, 50% or more of the total value or voting power of which is owned, directly or indirectly, by the Company; 

 

	 	(iii)	A person, or more than one Person Acting as a Group, that owns, directly or indirectly, 50% or more of the total value or voting power of all the outstanding stock of
the Company; or 

  

	 	(iv)	An entity, at least 50% of the total value or voting power of which is owned, directly or indirectly, by a person described in paragraph (iii).

 A person’s status is determined immediately after the transfer of the assets. For example, a transfer to a
corporation in which the Company has no ownership interest before the transaction, but which is a majority-owned subsidiary of the Company after the transaction is not treated as a Change of Ownership of a Substantial Portion of Assets of the
Company. 
  

	 	(d)	Persons Acting as a Group. Persons shall not be considered to be acting as a group solely because they purchase or own stock of the same corporation at the same
time or as a result of the same public offering. However, persons shall be considered to be acting as a group if they are owners of a corporation that enters into a merger, consolidation, purchase or acquisition of stock, or similar business
transaction with the Company. If a person, including an entity, owns stock in both corporations that enter into a merger, consolidation, purchase or acquisition of stock, or similar transaction, such shareholder is considered to be acting as a group
with other shareholders in a corporation prior to the transaction giving rise to the change and not with respect to the ownership interest in the other corporation. 

  
 13 

 7.2 Potential Change in Control. A “Potential Change in Control” shall
include any of the following: 
  

	 	(a)	The delivery to the Company by any “person,” as defined in Section 13(d)(3) of The Securities Exchange Act of 1934 (the “Act”), of a statement
containing the information required by Schedule 13-D under the Act, or any amendment to any such statement, that shows that such person has acquired, directly or indirectly, the beneficial ownership of (1) more than twenty percent (20%) of
any class of equity security of the Company entitled to vote as a class in the election or removal from office of directors, or (2) more than twenty percent (20%) of the voting power of any group of classes of equity securities of the
Company entitled to vote as a single class in the election or removal from office of directors. 

  

	 	(b)	The Company becomes aware that preliminary or definitive copies of a proxy statement and information statement or other information have been filed with the Securities
and Exchange Commission pursuant to Rule 14a-6, Rule 14c-5 or Rule 14f-l under the Act relating to a proposed change in control of the Company. 

  

	 	(c)	The delivery to the Company pursuant to Rule 14d-3 under the Act of a Tender Offer Statement relating to equity securities of the Company. 

 

	 	(d)	The Board adopts a resolution to the effect that for purposes of the Plan a Potential Change in Control has occurred. 

7.3 Additional Service and Compensation Upon Change in Control. With respect to a Participant who, pursuant to contract with the
Company, is entitled to compensation from the Company for an additional 36 months in the event that after a Change in Control the Participant’s employment is terminated by the Company or an Affiliate under circumstances described in the
contract, such Participant’s years of Service under Article II, and Supplemental Retirement Pension under Section 4.2 or Supplemental Retirement Account under Section 5.2, as applicable, shall be calculated as if the Participant had
continued in employment with the Company for an additional 36 months at the rate of Compensation in effect immediately prior to his or her employment termination; provided that, in no event shall the counting of a Participant’s Compensation
during this 36-month period reduce his or her Final Average Compensation figure below its highest level prior to the Participant’s separation from Service. 
 7.4 Waiver of Service and Age Requirements Upon Change in Control. A Participant who separates from service within 24 months following a Change in Control for any reason other than a termination by
the Company for Good Cause, but prior to Early Retirement, shall be eligible for the Supplemental Retirement Pension specified in Section 4.2, rather than the Supplemental Retirement Pension specified in Section 4.4, commencing at Normal
Retirement. Notwithstanding the previous sentence, such a Participant may elect to begin receiving the portion of his or her Supplemental Retirement Pension that constitutes his or her Pre-2005 Benefit pursuant to this Section 7.4 at any time
after attaining age 55 years, subject to the reduction specified in Section 4.3. Such election shall have no effect on the distribution of his or her Post-2004 Benefit at his or her Normal Retirement Date. 

  
 14 

 7.5 Funding of Plan Benefits Upon Potential Change in Control. Upon a Potential
Change in Control, the Plan Administrator shall identify the amount by which the present value of all benefits earned to date under the Plan (after offsets) exceeds the then fair market value of the applicable Trust assets, calculated using the
Pension Benefit Guaranty Corporation immediate annuity interest rate as of the date of the Potential Change in Control, the 1983 GAM mortality tables, and the most valuable optional payment form (the “Full Funding Amount”), and the Company
shall contribute such Full Funding Amount to the Trust. Each Participant’s benefits for purposes of calculating present value shall be the highest benefit the Participant would have under the Plan within the six months following a Potential
Change in Control, assuming that the Participant’s employment continues for six months at the same rate of Compensation, and that the Participant receives any benefit enhancement provided by the Plan, or any other agreement, upon a Change in
Control. 
 7.6 Plan Administration and Amendment Upon a Change in Control. Upon and after a Change in Control, the
Company no longer shall have the power to appoint or remove members of the Benefits Committee or ONC Committee, nor the power to approve legal counsel or actuaries employed by such committees. Upon and after a Change in Control, only the respective
committee members shall have the power to appoint or remove members. If, at any time after a Change in Control, all members of the Benefits Committee or ONC Committee have been removed or resigned, then all of the powers, rights and duties vested in
such committee by Article IX below shall be vested in the trustee of the Trust. 
 7.7 Plan Administrator Discretion to Pay
Lump Sum After a Change in Control. Upon and after a Change in Control, the Plan Administrator may, in its sole discretion, distribute, or cause the trustee under the Trust to distribute, to a Participant or a surviving spouse, the present value
(determined in accordance with the assumptions in Section 12.11) of the Participant’s Pre-2005 Benefit, or the portion of Supplemental Disability Pension or the surviving spouse’s Supplemental Spouse Pension attributable to his or her
Pre-2005 Benefit, payable under the Plan in a lump sum payment. The Plan Administrator shall distribute, or cause the trustee under the Trust to distribute, the present value of the Participant’s Post-2004 Benefit. 

7.8 Lump Sum Election. Each calendar year, a Participant shall have the right to elect to receive the present value (determined in
accordance with the assumptions in Section 12.11) of the portion of the Participant’s Supplemental Retirement Pension or the balance of the Participant’s Supplemental Retirement Account that constitutes the Participant’s Pre-2005
Benefit or the Participant’s Supplemental Disability Pension, in a lump sum if: 
  

	 	(a)	a Change in Control occurs in the calendar year subsequent to the calendar year in which the election is made; and 

 

	 	(b)	(i) within 24 months following the Change in Control any one of the payment triggering conditions set forth in the Change in Control and Termination Agreement between
the Company and the Participant shall have occurred; or 

  
 15 

	 	(ii)	if no Change in Control and Termination Agreement is in effect between the Company and the Participant on the date of the Change in Control and within 24 months
following the Change in Control the employment of the Participant with the Company is terminated by the Company for any reason other than Good Cause or the Participant terminates his or her employment with the Company for Good Reason.

 Such election shall be irrevocable for the calendar year to which it applies. A distribution pursuant to this Section shall be
made as soon as practicable following the Participant’s separation from Service. Notwithstanding the preceding provisions of this Section, a Participant had the right to make the election set forth in this Section at any time during the first
three (3) months of calendar year 2003 with respect to a Change in Control that occurred during the last nine (9) months of calendar year 2003. Any such election was irrevocable for calendar year 2003 and was subject to the other
provisions of this Section. 
 7.9 Definitions. 

 

	 	(a)	“Good Cause” shall be deemed to exist if, and only if: 

  

	 	(i)	the Participant engages in acts or omissions constituting dishonesty, intentional breach of fiduciary obligation or intentional wrongdoing or malfeasance, in each case
that results in substantial harm to the Company; or 

  

	 	(ii)	the Participant is convicted of a criminal violation involving fraud or dishonesty. 

 

	 	(b)	“Good Reason” shall be deemed to exist if, and only if: 

  

	 	(i)	there is a significant change in the nature or the scope of the Participant’s authorities or duties; 

 

	 	(ii)	there is a significant reduction in the Participant’s monthly rate of base salary, his or her opportunity to earn a bonus under an incentive bonus compensation
plan maintained by the Company or his or her benefits; or 

  

	 	(iii)	the Company changes by 100 miles or more the principal location in which the Participant is required to perform services. 

ARTICLE VIII 
 Beneficiary Designation 
 8.1 Beneficiary Designation. Each
Participant shall have the right, at any time, to designate one or more persons or an entity as Beneficiary (both primary as well as secondary) to whom benefits under the Plan shall be paid in the event of the Participant’s death prior to
complete distribution of the Participant’s interest under the Plan. Each Beneficiary designation shall be in a written form prescribed by the Benefits Committee and shall be effective only when filed with the Benefits Committee during the
Participant’s lifetime. 

  
 16 

 If the Participant designates multiple beneficiaries, he or she shall designate the
percentage, in whole numbers, allocated to each such beneficiary. 
 8.2 Changing Beneficiary. Any Beneficiary
designation may be changed by a Participant without the consent of the previously named Beneficiary by the filing of a new designation with the Benefits Committee. The filing of a new designation shall cancel all designations previously filed.

the designation is void or if the beneficiary designated by a deceased Participant dies before the Participant or before complete distribution of the Participant’s benefits, the Participant’s beneficiary shall be the person in the first of
the following classes in which there is a survivor: 
  

	 	(a)	The Participant’s spouse;

	 	(c)	a description of any additional material or information necessary for the claimant to perfect the claim, together with an explanation of why such material or
information is necessary; and 

  

	 	(d)	an explanation of the Plan’s review procedure. 

 10.4 Reconsideration of Denied Claim. Within 60 days of the receipt by the claimant of the written notice of denial of the claim, or within 60 days after the claim is deemed denied as set forth
above, if applicable, the claimant or duly authorized representative may file a written request with the Benefits Committee that it conduct a full and fair review of the denial of the claimant’s claim for benefits. If the claimant or duly
authorized representative fails to request such a reconsideration within such 60 day period, it shall be conclusively determined for all purposes of the Plan that the denial of such claim by the Benefits Committee is correct. In connection with the
claimant’s appeal of the denial of his or her benefit, the claimant may review pertinent documents and may submit issues and comments in writing. 
 The Benefits Committee shall render a decision on the claim appeal promptly, but not later than 60 days after receiving the claimant’s request for review, unless, in the discretion of the Benefits
Committee, special circumstances require an extension of time for processing, in which case the 60-day period may be extended to 120 days. The Benefits Committee shall notify the claimant in writing of any such extension. The notice of decision
shall be in writing and shall include specific reasons for the decision, written in a manner calculated to be understood by the claimant, as well as specific references to the pertinent Plan provisions on which the decision is based. If the decision
on review is not furnished within the time period set forth above, the claim shall be deemed denied on review. 
 If such
determination is favorable to the claimant, it shall be binding and conclusive. If such determination is adverse to such claimant, it shall be binding and conclusive unless the claimant or his duly authorized representative notifies the Benefits
Committee within 90 days after the mailing or delivery to the claimant by the Benefits Committee of its determination that claimant intends to institute legal proceedings challenging the determination of the Benefits Committee and actually
institutes such legal proceedings within 180 days after such mailing or delivery.

 ARTICLE XI 

Plan Amendment and Termination 
 11.1 Plan Amendment. The ONC Committee or the Board shall have the authority to amend the Plan. The ONC Committee or the Board shall have the exclusive authority to amend the Plan regarding
eligibility for the Plan, the amount or level of benefits awarded under the Plan, and the time and form of payments for benefits from the Plan. In addition, the ONC Committee or the Board shall also have the exclusive authority to make amendments
that constitute a material increase in compensation, any change requiring action or consent by a committee of the Board pursuant to the rules of the Securities and Exchange Commission, the New York Stock Exchange or other applicable law, or such
other material changes to the Plan such that approval of the Board is required. Unless otherwise determined by the ONC Committee, the Benefits Committee shall have the authority to amend the Plan in all respects that are not exclusively reserved to
the ONC Committee or the Board. 
 The respective committee may at any time amend the Plan by written instrument, notice of
which is given to all Participants, and to Beneficiaries receiving installment payments. Notwithstanding the preceding sentence, no amendment shall reduce the amount accrued in any Account prior to the date such notice of the amendment is given.

 11.2 Plan Termination. The ONC Committee or the Company may terminate the Plan at any time, except that any benefits
that are payable due to a Retirement, death, Disability, or other separation from Service occurring prior to the amendment or termination shall not be reduced or discontinued. No amendment or termination of the Plan shall directly or indirectly
deprive any current or former Participant (or surviving spouse) of all or any portion of any Supplemental Retirement Benefit, Supplemental Disability Pension, Supplemental Spouse Pension, or Supplemental Retirement Account, the payment of which has
commenced prior to the effective date of such amendment or termination, or which would be payable if the Participant experienced a separation from Service for any reason on such effective date. Upon termination of the Plan, distribution of a
Participant’s Supplemental Retirement Benefits, Supplemental Disability Pension, Supplemental Retirement Account, or Supplemental Spouse Pension shall be made to the Participant or his or her surviving spouse or beneficiary in the manner and at
the time described in Articles IV, V and VI of the Plan. In addition, no additional Supplemental Retirement Benefits, Supplemental Disability Pension, Supplemental Spouse Pension, or Compensation Credits or Supplemental Credits under a Supplemental
Retirement Account, shall be earned after termination of the Plan, except as provided in Section 7.3. 
 ARTICLE XII

 Miscellaneous 
 12.1 Plan Financing. Except as set forth below in this Section and in Section 7.5, benefits under the Plan shall be paid from the general assets of the Company. To the extent any Participant
or surviving spouse or other designated beneficiary acquires a right to receive payments hereunder, such right shall be no greater than the right of any other unsecured creditor of the Company. Notwithstanding the foregoing, the Company has entered
into a trust agreement (‘Trust Agreement”) whereby the Company agrees to contribute to a trust (“Trust”) for the purpose of accumulating assets to assist the Company in fulfilling its obligations to Participants and surviving
spouses or other designated beneficiaries hereunder. Such Trust includes the provision that all assets of the Trust shall be subject to the creditors of the Company in the event of its insolvency. 

  
 20 

 12.2 Non-Compete and Related Provisions. Benefits under the Plan may be forfeited if:

  

	 	(a)	A Participant, while employed by the Company or within a period of three years after the Participant’s separation from Service for any reason, including Retirement
(the “Restrictive Period”), engages in activity or employment that directly or indirectly competes with the business of the Company or its Affiliates, including, but not by way of limitation, by directly or indirectly owning, managing,
operating, controlling, financing, or by directly or indirectly serving as an employee, officer or director of or consultant to, or by soliciting or inducing, or attempting to solicit or induce, any employee or agent of the Company or its Affiliates
to terminate employment with the Company or its Affiliates, and become employed by, any person, firm, partnership, corporation, trust or other entity that provides commodities, products or services to customers of the Company or its Affiliates of
the same type as commodities, products or services provided by the Company or its Affiliates (the “Restrictive Covenant”). The foregoing Restrictive Covenant shall not prohibit a Participant from owning directly or indirectly capital stock
or similar securities which are listed on a securities exchange or quoted on the National Association of Securities Dealers Automated Quotation System which do not represent more than 1% of the outstanding capital stock of any such entity; or

  

	 	(b)	A Participant performs any action or makes any statement that is detrimental to the Company or its Affiliates, unless such action or statement is retracted to the
Company’s satisfaction after the Participant is notified regarding such action or statement. 

 12.3
Nonguarantee of Employment. Participation in the Plan does not limit the right of the Company or an Affiliate to discharge any individual with or without cause. 
 12.4 Nonalienation of Benefits. Neither a Participant nor any other person shall have any right to commute, sell, assign, transfer, pledge, anticipate, mortgage, or otherwise encumber, transfer,
hypothecate, or convey in advance of actual receipt the amounts, if any, payable hereunder, or any part thereof or 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. 
 Notwithstanding the preceding paragraph, the benefit of any Participant shall
be subject to and payable in the amount determined in accordance with any qualified domestic relations order, as that term is defined in Section 206(d)(3) of ERISA. The Plan Administrator shall

  
 21 

 
provide for payment in a lump sum from a Participant’s benefit to an alternate payee (as defined in Code Section 414(p)(8)) as soon as administratively practicable following receipt of
such order. Any federal, state or local income tax associated with such payment shall be the responsibility of the alternate payee. The balance of a benefit that is subject to any qualified domestic relations order shall be reduced by the amount of
any payment made pursuant to such order. 
 12.5 Indemnification. 

 

	 	(a)	Limitation of Liability. Notwithstanding any other provision of the Plan or the Trust, none of the Company, any member of the Benefits Committee or ONC
Committee, nor an individual acting as an employee or agent of any of them, shall be liable to any Participant or former Participant, or any surviving spouse or other designated beneficiary of any Participant or former Participant, for any claim,
loss, liability or expense incurred in connection with the Plan or the Trust, except when the same shall have been judicially determined to be due to the willful misconduct of such person. 

 

	 	(b)	Indemnity. The Company shall indemnify and hold harmless each member of the Benefits Committee and the ONC Committee, or any employee of the Company or any
individual acting as an employee or agent of either of them (to the extent not indemnified or saved harmless under any liability insurance or any other indemnification arrangement with respect to the Plan or the Trust) from any and all claims,
losses, liabilities, costs and expenses (including attorneys’ fees) arising out of any actual or alleged act or failure to act made in good faith pursuant to the provisions of the Plan, including expenses reasonably incurred in the defense of
any claim relating thereto with respect to the administration of the Plan or the Trust, except that no indemnification or defense shall be provided to any person with respect to any conduct that has been judicially determined, or agreed by the
parties, to have constituted willful misconduct on the part of such person, or to have resulted in his or her receipt of personal profit or advantage to which he or she is not entitled. In connection with the indemnification provided by the
preceding sentence, expenses incurred in defending a civil or criminal action, suit or proceeding, or incurred in connection with a civil or criminal investigation, may be paid by the Company in advance of the final disposition of such action, suit,
proceeding, or investigation, as authorized by the Plan Administrator in the specific case, upon receipt of an undertaking by or on behalf of the party to be indemnified to repay such amount unless it shall ultimately be determined that the person
is entitled to be indemnified by the Company pursuant to this paragraph. 

 12.6 Severability. Each of the
Sections contained in the Plan, and each provision in each Section, shall be enforceable independently of every other Section or provision in the Plan, and the invalidity or unenforceability of any Section or provision shall not invalidate or render
unenforceable any other Section or provision contained herein. If any Section or provision in a Section is found invalid or unenforceable, it is the intent of the parties that a court of competent jurisdiction shall reform the Section or provision
to produce its nearest enforceable economic equivalent. 

  
 22 

 12.7 Action by Company. Any action required of, or permitted by, the Company under
the Plan shall be by resolution of the respective committee identified herein, or by a person or persons authorized by resolution of the such committee. 
 12.8 Protective Provisions. A Participant shall cooperate with the Company by furnishing any and all information requested by the Company and its Affiliates in order to facilitate the payment of
benefits hereunder, and by taking such physical examinations as the Company and its Affiliates may deem necessary and taking such other action as may be requested by the Company and its Affiliates. 

12.9 Governing Law. The provisions of the Plan shall be construed and interpreted according to the laws of the State of Indiana,
except as preempted by federal law. 
 12.10 Notice. Any notice required or permitted under the Plan shall be sufficient
if in writing and hand delivered or sent by registered or certified mail. Such notice shall be deemed as 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. Mailed notice to the Plan Administrator shall be directed to the Company’s address. Mailed notice to a Participant, a surviving spouse or other designated beneficiary shall be directed to the individual’s last known address
in the Company’s records. 
 12.11 Successors. The provisions of the Plan shall bind and inure to the benefit of the
Company, its Affiliates and their successors and assigns. The term successors as used herein shall include any corporate or other business entity that shall, whether by merger, consolidation, purchase, or otherwise, acquire all or substantially all
of the business and assets of the Company, and successors of any such corporation or other business entity. 
 12.12
Actuarial Assumptions. Unless otherwise provided in the Plan, all actuarial adjustments necessary to determine the amount, form or timing of any distribution shall be based on the same actuarial assumptions used for the pension a Participant
is eligible to receive under the NiSource Pension Plan. 
 12.13 Tax Savings. 

 

	 	(a)	 Notwithstanding anything to the contrary contained in the Plan, (1) in the event that the Internal Revenue Service prevails in its claim that
benefits under the Plan constitute taxable income to a Participant; his or her spouse or other designated beneficiary, for any taxable year, prior to the taxable year in which such benefits are distributed to him or her, or (2) in the event
that legal counsel satisfactory to the Company and the applicable Participant, his or her spouse or other designated beneficiary, renders an opinion that the Internal Revenue Service would likely prevail in such a claim, the Pre-2005 Benefit, to the
extent constituting taxable income, shall be immediately distributed to the Participant, his or her spouse or other designated beneficiary. For purposes of this Section, the Internal Revenue

  
 23 

	 	
Service shall be deemed to have prevailed in a claim if such claim is upheld by a court of final jurisdiction, or, if based upon an opinion of legal counsel satisfactory to the Company and the
Participant, his or her spouse or other designated beneficiary, the Plan fails to appeal a decision of the Internal Revenue Service, or a court of applicable jurisdiction, with respect to such claim to an appropriate Internal Revenue Service appeals
authority or to a court of higher jurisdiction within the appropriate time period. 

  

	 	(b)	Notwithstanding anything to the contrary contained in the Plan, (I) in the event that the Internal Revenue Service prevails in its claim that benefits under the
Plan constitute taxable income under Code Section 409A, and guidance and regulations thereunder, to a Participant, his or her spouse or other designated beneficiary, for any taxable year prior to the taxable year in which such benefits are
distributed to him or her, or (2) in the event that legal counsel satisfactory to the Company and the applicable Participant, his or her spouse or other designated beneficiary, renders an opinion that the Internal Revenue Service would likely
prevail in such a claim, the Post-2004 Benefit or Supplemental Spouse Pension, to the extent constituting taxable income, shall be immediately distributed to the Participant, his or her spouse or other designated beneficiary. For purposes of this
Section, the Internal Revenue Service shall be deemed to have prevailed in a claim if such claim is upheld by a court of final jurisdiction, or, if based upon an opinion of legal counsel satisfactory to the Company and the Participant, his or her
spouse or other designated beneficiary, the Plan fails to appeal a decision of the Internal Revenue Service, or a court of applicable jurisdiction, with respect to such claim to an appropriate Internal Revenue Service appeals authority or to a court
of higher jurisdiction within the appropriate time period.
