this Agreement. 
 SECTION 3 

REGISTERED EXCHANGE OFFER 

(a) Unless the Exchange Offer shall not be permissible under applicable law or Commission policy (after the procedures set forth in
Section 6(a) hereof have been complied with), the Company and the Guarantors shall (i) file with the Commission a Registration Statement under the Securities Act relating to the Exchange Securities and the Exchange Offer, (ii) use
their reasonable best efforts to cause such Registration Statement to become effective under the Securities Act, (iii) in connection with the foregoing, file (A) all pre-effective amendments to such Registration Statement as may be
necessary in order to cause such Registration Statement to become effective, (B) if applicable, a post-effective amendment to such Registration Statement pursuant to Rule 430A under the Securities Act and (C) cause all necessary filings in
connection with the registration and qualification of the Exchange Securities to be made under the state securities or blue sky laws of such jurisdictions as are necessary to permit Consummation of the Exchange Offer, and (iv) promptly after
such Registration Statement is declared effective, commence the Exchange Offer. The Exchange Offer Registration Statement shall be on the appropriate form permitting registration of the Exchange Securities to be offered in exchange for the Transfer
Restricted Securities and to permit resales of Securities held by Broker-Dealers as contemplated by Section 3(c) hereof. 
 (b) If an
Exchange Offer Registration Statement is required pursuant to Section 3(a) above, the Company and the Guarantors shall use their reasonable best efforts to keep the Exchange Offer open for not less than 20 Business Days (or longer if required
by applicable law) after the date notice of the Exchange Offer is mailed or otherwise delivered to the Holders. The Company and the Guarantors shall cause each Exchange Offer to comply with all applicable federal and state securities laws. No
securities other than the Exchange Securities shall be included in the Exchange Offer Registration Statement. If an Exchange Offer Registration Statement is required pursuant to Section 3(a) above, the Company and the Guarantors shall use their
reasonable best efforts to Consummate the Exchange Offer on or prior to the 360th calendar day following the Closing Date (or if such 360th day is not a Business Day, the next succeeding Business Day). 

(c) The Company shall indicate in a “Plan of Distribution” section contained in the Prospectus forming a part of any Exchange Offer
Registration Statement that any Broker-Dealer who holds Initial Securities that are Transfer Restricted Securities and that were acquired for its own account as a result of market-making activities or other trading activities (other than Transfer
Restricted Securities acquired directly from the Company), may exchange such Initial Securities pursuant to the Exchange Offer; however, such Broker-Dealer may be deemed to be an “underwriter” within the meaning of the Securities Act and
must, therefore, deliver a prospectus meeting the requirements of the Securities Act in connection with any resales of the Exchange Securities received by such Broker-Dealer in the Exchange Offer, which prospectus delivery requirement may be
satisfied by the delivery by such Broker-Dealer of the Prospectus 

  
 5 

 
contained in the Exchange Offer Registration Statement. Such “Plan of Distribution” section shall also contain all other information with respect to such resales by Broker-Dealers that
the Commission may require in order to permit such resales pursuant thereto, but such “Plan of Distribution” shall not name any such Broker-Dealer or disclose the amount of Initial Securities held by any such Broker-Dealer except to the
extent required by the Commission as a result of a change in policy after the date of this Agreement. 
 If an Exchange Offer Registration
Statement is required pursuant to Section 3(a) above, the Company and the Guarantors shall use their reasonable best efforts to keep the Exchange Offer Registration Statement continuously effective, supplemented and amended as required by the
provisions of Section 6(c) hereof to the extent necessary to ensure that it is available for resales of Securities acquired by Broker-Dealers for their own accounts as a result of market-making activities or other trading activities, and to
ensure that it conforms with the requirements of this Agreement, the Securities Act and the policies, rules and regulations of the Commission as announced from time to time, for a period ending on the earlier of (i) 180 days from the date on
which the Exchange Offer Registration Statement is declared effective and (ii) the date on which Broker-Dealers are no longer required to deliver a prospectus in connection with market-making or other trading activities. 

The Company shall provide sufficient copies of the latest version of such Prospectus to Broker-Dealers promptly upon request at any time
during such 180-day (or shorter as provided in the foregoing sentence) period in order to facilitate such resales. 
 SECTION 4 

SHELF REGISTRATION 
 (a)
Shelf Registration. If (i) the Company and the Guarantors are not required to file an Exchange Offer Registration Statement or to Consummate the Exchange Offer for the Initial Securities because the Exchange Offer is not permitted by
applicable law or Commission policy (after the procedures set forth in Section 6(a) hereof have been complied with), (ii) for any other reason the Exchange Offer for the Securities is not Consummated within 360 calendar days following the
Closing Date (or if such 360th day is not a Business Day, the next succeeding Business Day), or (iii) with respect to any Holder of Transfer Restricted Securities (A) such Holder is prohibited by applicable law or Commission policy from
participating in the Exchange Offer, or (B) such Holder may not resell the Exchange Securities acquired by it in the Exchange Offer to the public without delivering a prospectus and that the Prospectus contained in the Exchange Offer
Registration Statement is not appropriate or available for such resales by such Holder, or (C) such Holder is a Broker-Dealer and holds Initial Securities acquired directly from the Company or one of its affiliates, then, upon such
Holder’s request, the Company and the Guarantors shall 
 (x) cause to be filed, at their expense, a shelf registration
statement pursuant to Rule 415 under the Securities Act, which may be an amendment to the Exchange Offer Registration Statement (in either event, the “Shelf Registration Statement”) as promptly as practicable (but in no event later than 90
days after such obligation to file arises), which Shelf Registration Statement shall provide for resales of all Transfer Restricted Securities the Holders of which shall have provided the information required pursuant to Section 4(b) hereof;
and 

  
 6 

 (y) use their reasonable best efforts to cause such Shelf Registration Statement
to be declared effective (or become automatically effective) under the Securities Act prior to the date that is 120 days after such obligation to file arises. 

The Company and the Guarantors shall use their reasonable best efforts to keep any such Shelf Registration Statement continuously effective,
supplemented and amended as required by the provisions of Sections 6(b) and (c) hereof to the extent necessary to ensure that it is available for resales of Initial Securities by the Holders of Transfer Restricted Securities entitled to the
benefit of this Section 4(a), and to ensure that it conforms with the requirements of this Agreement, the Securities Act and the policies, rules and regulations of the Commission as announced from time to time, until the earlier of one year
following the effective date of such Shelf Registration Statement or such time when all the Initial Securities covered by such Shelf Registration Statement have been sold pursuant to such Shelf Registration Statement or are freely tradeable by
non-affiliates of the Company pursuant to Rule 144. 
 (b) Provision by Holders of Certain Information in Connection with the Shelf
Registration Statement. No Holder of Transfer Restricted Securities may include any of its Transfer Restricted Securities in any Shelf Registration Statement pursuant to this Agreement unless and until such Holder furnishes to the Company in
writing, within 20 Business Days after receipt of a request therefor, such information as the Company may reasonably request for use in connection with any Shelf Registration Statement or Prospectus or preliminary Prospectus included therein. Each
Holder as to which any Shelf Registration Statement is being effected agrees to furnish promptly to the Company all information required to be disclosed in order to make the information previously furnished to the Company by such Holder true and
correct in all material respects and not materially misleading. 
 SECTION 5 

ADDITIONAL INTEREST 
 If
(a) the Exchange Offer is not Consummated on or prior to the 360th calendar day following the Closing Date (or if such 360th day is not a Business Day, the next succeeding Business Day), (b) a Shelf Registration Statement applicable to the
Securities is not filed or declared effective (or does not automatically become effective) on or prior to the applicable date specified in Section 4(a)(x) and (y) or (c) a Shelf Registration Statement applicable to the Securities is
declared effective (or automatically becomes effective) as required but thereafter fails to remain effective or the Prospectus contained therein becomes unusable in connection with resales for more than 60 consecutive days (each such event referred
to in clauses (a), (b) and (c) above, a “Registration Default”), the Company hereby agrees that, as liquidated damages, the interest rate borne by the Transfer Restricted Securities shall be increased by 0.25% per annum
during the 90-day period immediately following the occurrence of any Registration Default and shall increase by 0.25% per annum at the end of each subsequent 90-day period, but in no event shall such increase exceed 0.50% per annum
(“Additional Interest”), until the earlier of the completion of the Exchange Offer or the effectiveness of the Shelf Registration Statement (or such Shelf Registration Statement no longer being required to be effective or the Prospectus

  
 7 

 
again becomes usable), after which the interest rate borne by the relevant Transfer Restricted Securities will be reduced to the original interest rate borne by such Transfer Restricted
Securities. Notwithstanding the foregoing, if, after the date such Additional Interest ceases to accrue, another Registration Default occurs, Additional Interest will again commence accruing pursuant to the foregoing provisions. 

The Additional Interest set forth above shall be the exclusive monetary remedy available to Holders for each Registration Default. 

All obligations of the Company and the Guarantors set forth in the preceding paragraph that are outstanding with respect to any Transfer
Restricted Security at the time such security ceases to be a Transfer Restricted Security shall survive until such time as all such obligations with respect to such security shall have been satisfied in full. 

SECTION 6 
 REGISTRATION
PROCEDURES 
 (a) Exchange Offer Registration Statement. In connection with each Exchange Offer, the Company and the Guarantors
shall comply with all of the provisions of Section 6(c) hereof, shall use their reasonable best efforts to effect such exchange to permit the sale of Transfer Restricted Securities being sold in accordance with the intended method or methods of
distribution thereof. As a condition to its participation in an Exchange Offer pursuant to the terms of this Agreement, each Holder of Transfer Restricted Securities shall furnish, upon the request of the Company, prior to the Consummation thereof,
a written representation to the Company (which may be contained in the letter of transmittal contemplated by the Exchange Offer Registration Statement) to the effect that (A) it is not an affiliate of the Company, (B) it is acquiring the
Exchange Securities in its ordinary course of business and (C) at the time of the commencement of the Exchange Offer, it has no arrangement with any Person to participate in the distribution (within the meaning of the Securities Act) of the
Exchange Securities to be issued in the Exchange Offer. In addition, all such Holders of Transfer Restricted Securities shall otherwise cooperate in the Company’s preparations for the Exchange Offer. Each Holder, including any Holder that is a
Broker-Dealer, will be required to acknowledge and agree that any such Holder using the Exchange Offer to participate in a distribution of the securities to be acquired in the Exchange Offer (1) could not under Commission policy as in effect on
the date of this Agreement rely on the position of the Commission enunciated in Morgan Stanley and Co., Inc. (available June 5, 1991) and Exxon Capital Holdings Corporation (available May 13, 1988), as interpreted in the
Commission’s letter to Shearman & Sterling dated July 2, 1993, and similar no-action letters, and (2) must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a secondary
resale transaction and that such a secondary resale transaction should be covered by an effective registration statement containing the selling security holder information required by Item 507 or 508, as applicable, of Regulation S-K if the
resales are of Exchange Securities obtained by such Holder in exchange for Initial Securities acquired by such Holder directly from the Company. 

(b) Shelf Registration Statement. In connection with the Shelf Registration Statement, the Company and the Guarantors shall comply with
all the provisions of Section 6(c) hereof and shall use their reasonable best efforts to effect such registration to permit the sale of 

  
 8 

 
the Transfer Restricted Securities being sold in accordance with the intended method or methods of distribution thereof, and pursuant thereto the Company and the Guarantors will as expeditiously
as practicable prepare and file with the Commission a Registration Statement relating to the registration on any appropriate form under the Securities Act, which form shall be available for the sale of the Transfer Restricted Securities in
accordance with the intended method or methods of distribution thereof. 
 (c) General Provisions. In connection with any
Registration Statement and any Prospectus required by this Agreement to permit the sale or resale of Transfer Restricted Securities (including, without limitation, any Registration Statement and the related Prospectus required to permit resales of
Securities by Broker-Dealers), the Company and the Guarantors shall: 
 (i) use reasonable best efforts to keep such
Registration Statement continuously effective and provide all requisite financial statements (including, if required by the Securities Act or any regulation thereunder, financial statements of the Guarantors) for the period specified in
Section 3 or 4 hereof, as applicable; upon the occurrence of any event that would cause any such Registration Statement or the Prospectus contained therein (A) to contain an untrue statement of a material fact or omit to state a material
fact necessary to make the statement therein not misleading or (B) not to be effective and usable for resale of Transfer Restricted Securities during the period required by this Agreement, the Company shall file promptly an appropriate
amendment to such Registration Statement, in the case of clause (A), correcting any such misstatement or omission, and, in the case of either clause (A) or (B), use its reasonable best efforts to cause such amendment to be declared effective
and such Registration Statement and the related Prospectus to become usable for their intended purposes as soon as practicable thereafter; 

(ii) prepare and file with the Commission such amendments and post-effective amendments to such Registration Statement as may
be necessary to keep such Registration Statement effective for the applicable period set forth in Section 3 or 4 hereof, as applicable, or such shorter period as will terminate when all Transfer Restricted Securities covered by such
Registration Statement have been sold; cause the Prospectus to be supplemented by any required Prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 under the Securities Act, and to comply fully with the applicable
provisions of Rules 424, 430A and 430B under the Securities Act in a timely manner; and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration Statement during the applicable
period in accordance with the intended method or methods of distribution by the sellers thereof set forth in such Registration Statement or supplement to the Prospectus; 

(iii) advise the underwriter(s), if any, and any selling Holders named in any Shelf Registration Statement promptly
and, if requested by such Persons, confirm such advice in writing, (A) when the Prospectus or any prospectus supplement or post-effective amendment has been filed, and, with respect to such Registration Statement or any post-effective
amendment thereto, when the same has become effective, (B) of any 

  
 9 

 
request by the Commission for amendments to the Registration Statement or amendments or supplements to the Prospectus or for additional information relating thereto, (C) of the issuance by
the Commission of any stop order suspending the effectiveness of such Registration Statement under the Securities Act or of the suspension by any state securities commission of the qualification of the Transfer Restricted Securities for offering or
sale in any jurisdiction, or the initiation of any proceeding for any of the preceding purposes, or (D) of the existence of any fact or the happening of any event that makes any statement of a material fact made in such Registration Statement,
the Prospectus, any amendment or supplement thereto, or any document incorporated by reference therein untrue, or that requires the making of any additions to or changes in such Registration Statement or the Prospectus in order to make the
statements therein not misleading; and if at any time the Commission shall issue any stop order suspending the effectiveness of the Registration Statement, or any state securities commission or other regulatory authority shall issue an order
suspending the qualification or exemption from qualification of the Transfer Restricted Securities under state securities or blue sky laws, use their reasonable best efforts to obtain the withdrawal or lifting of such order at the earliest
reasonably possible time; 
 (iv) furnish without charge to each selling Holder named in any Shelf Registration Statement and
each of the underwriter(s), if any, before filing with the Commission, copies of such Registration Statement or any Prospectus included therein or any amendments or supplements to any such Registration Statement or Prospectus (including all
documents incorporated by reference after the initial filing of such Registration Statement), which documents will be subject to the review and comment of such Holders and underwriter(s) in connection with such sale, if any, for a period of at least
five Business Days, and the Company will not file any such Registration Statement or Prospectus or any amendment or supplement to any such Registration Statement or Prospectus (including all such documents incorporated by reference) to which a
Holder of Transfer Restricted Securities covered by such Registration Statement or the underwriter(s), if any, shall reasonably object in writing within five Business Days after the receipt thereof (such objection to be deemed timely made upon
confirmation of telecopy transmission within such period), it being understood that the objection of a selling Holder or underwriter, if any, shall be deemed to be reasonable only if such Registration Statement, amendment, Prospectus or supplement,
as applicable, as proposed to be filed, contains an untrue statement of a material fact or omits to state a material fact necessary to make the statements therein not misleading; 

(v) make available at reasonable times for inspection by the managing underwriter(s), if any, participating in any disposition
pursuant to any Shelf Registration Statement and any attorney or accountant retained by any of the underwriter(s), all financial and other records, pertinent corporate documents and properties of the Company and the Guarantors and cause the
Company’s and the Guarantors’ officers, directors and employees to supply all information reasonably requested by any such underwriter, attorney or accountant in connection with such Registration Statement or any post-effective amendment
thereto subsequent to the filing thereof and prior to its effectiveness and to participate in meetings with investors to the extent reasonably requested by the managing underwriter(s), if any; 

  
 10 

 (vi) if requested by any selling Holders or the underwriter(s), if any, promptly
incorporate in any Shelf Registration Statement or Prospectus, pursuant to a supplement or post-effective amendment if necessary, such information as such selling Holders and underwriter(s), if any, may reasonably request to have included therein,
including, without limitation, information relating to the “Plan of Distribution” of the Transfer Restricted Securities, information with respect to the principal amount of Transfer Restricted Securities being sold to such underwriter(s),
the purchase price being paid therefor and any other terms of the offering of the Transfer Restricted Securities to be sold in such offering; and make all required filings of such Prospectus supplement or post-effective amendment as soon as
reasonably practicable after the Company is notified of the matters to be incorporated in such Prospectus supplement or post-effective amendment; 

(vii) if not then rated, cause the Transfer Restricted Securities covered by any Shelf Registration Statement to be rated with
the appropriate rating agencies, if so requested by the Holders of a majority in aggregate principal amount of Securities covered thereby or the underwriter(s), if any; 

(viii) furnish to each selling Holder named in any Shelf Registration Statement and each of the underwriter(s), if any, without
charge, at least one copy of such Registration Statement, as first filed with the Commission, and of each amendment thereto, including financial statements and schedules, and, upon their request, all documents incorporated by reference therein and
all exhibits (including exhibits incorporated therein by reference); 
 (ix) deliver to each selling Holder named in any
Shelf Registration Statement and each of the underwriter(s), if any, without charge, as many copies of the Prospectus contained therein (including each preliminary prospectus) and any amendment or supplement thereto as such Persons reasonably may
request; the Company and the Guarantors hereby consent to the use of such Prospectus and any amendment or supplement thereto by each of the selling Holders and each of the underwriter(s), if any, in connection with the offering and the sale of the
Transfer Restricted Securities covered by such Prospectus or any amendment or supplement thereto; 
 (x) in the case of a
Shelf Registration Statement, enter into such agreements (including an underwriting agreement), and make such representations and warranties, and take all such other actions in connection therewith in order to expedite or facilitate the disposition
of the Transfer Restricted Securities pursuant to such Registration Statement, all to such extent as may be reasonably requested by any Holder of Transfer Restricted Securities or underwriter in connection with any sale or resale pursuant to such
Registration Statement; and, whether or not an underwriting agreement is entered into and whether or not the registration is an Underwritten Registration, the Company and the Guarantors shall: 

(A) furnish to each selling Holder and each underwriter, if any, in such substance and scope as they may request and as are
customarily made by issuers 

  
 11 

 
to underwriters in primary underwritten offerings, upon the date of the effectiveness of the Shelf Registration Statement: 

(1) a certificate, dated the date of effectiveness of the Shelf Registration Statement, signed by (y) the President or
any Vice President and (z) a principal financial or accounting officer of each of the Company and the Guarantors, confirming, as of the date thereof, the matters similar to those set forth in paragraphs (i), (ii) and (iii) of
Section 6(d) of the Purchase Agreement as adjusted to reflect the Company and the Guarantors as of the date thereof and such other matters as such parties may reasonably request; 

(2) an opinion, dated the date of effectiveness of the Shelf Registration Statement of counsel for the Company and the
Guarantors, covering such matters as such parties may reasonably request, and in any event including a customary statement substantially to the effect that such counsel has participated in conferences with officers and other representatives of the
Company and the Guarantors, representatives of the independent public accountants for the Company and the Guarantors, representatives of the underwriter(s), if any, and counsel to the underwriter(s), if any, in connection with the preparation of
such Shelf Registration Statement and the related Prospectus and have considered the matters required to be stated therein and the statements contained therein, although such counsel has not independently verified the accuracy, completeness or
fairness of such statements; and that such counsel advises that, on the basis of the foregoing, no facts came to such counsel’s attention that caused such counsel to believe that the Shelf Registration Statement, at the time such Shelf
Registration Statement or any post-effective amendment thereto became effective, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not
misleading, or that the Prospectus contained in such Shelf Registration Statement as of its date, contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading. Without limiting the foregoing, such counsel may state further that such counsel assumes no responsibility for, and has not independently verified, the accuracy, completeness or fairness
of the financial statements, notes and schedules and other financial data or reserves data included in any Shelf Registration Statement contemplated by this Agreement or the related Prospectus; and 

(3) a customary comfort letter, dated the date of effectiveness of the Shelf Registration Statement, from the Company’s

however, that neither the Company nor any Guarantor shall be required to register or qualify as a foreign corporation where it is not then so qualified or to take any action that would subject it to the service of process in suits or to taxation
in any jurisdiction where it is not then so subject; 
 (xii) shall issue, in accordance with the procedures of The
Depository Trust Company or upon the written request of any Holder of Initial Securities covered by a Shelf Registration Statement, Exchange Securities of each series having an aggregate principal amount equal to the aggregate principal amount of

(xiii) cooperate with the selling Holders and the underwriter(s), if any, to facilitate the timely preparation and delivery of

(xiv) use their reasonable best efforts to cause the Transfer Restricted Securities covered by any Shelf Registration Statement

subject to the proviso contained in Section 6(c)(xi) hereof; 

  
 13 

 (xv) if any fact or event contemplated by Section 6(c)(iii)(D) hereof shall
exist or have occurred, prepare a supplement or post-effective amendment to such Registration Statement or related Prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter delivered to
the purchasers of Transfer Restricted Securities, the Prospectus will not contain an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under
which they were made, not misleading; 
 (xvi) provide a CUSIP number for all Securities not later than the effective date of

ensure that all such Securities are eligible for deposit with The Depository Trust Company; 
 (xvii) cooperate and assist in
any filings required to be made with the FINRA and in the performance of any due diligence investigation by any underwriter (including any “qualified independent underwriter”) that is required to be retained in accordance with the rules
and regulations of the FINRA; 
 (xviii) otherwise use their reasonable best efforts to comply with all applicable rules and
regulations of the Commission, and make generally available to the Company’s security holders, as soon as practicable, a consolidated earnings statement meeting the requirements of Rule 158 (which need not be audited) for the twelve-month
period (A) commencing at the end of any fiscal quarter in which Transfer Restricted Securities are sold to underwriters in a firm commitment or best efforts Underwritten Offering or (B) if not sold to underwriters in such an offering,
beginning with the first month of the Company’s first fiscal quarter commencing after the effective date of the Shelf Registration Statement covering such Transfer Restricted Securities; 

(xix) cause the Indenture to be qualified under the Trust Indenture Act not later than the effective date of the first
Registration Statement required by this Agreement, and, in connection therewith, cooperate with the Trustee and the Holders of Securities to effect such changes to the Indenture as may be required for such Indenture to be so qualified in accordance
with the terms of the Trust Indenture Act; and execute and use their reasonable best efforts to cause the Trustee to execute, all documents that may be required to effect such changes and all other forms and documents required to be filed with the
Commission to enable such Indenture to be so qualified in a timely manner; and 
 (xx) provide promptly to each Holder upon
request each document filed with the Commission pursuant to the requirements of Section 13 and Section 15 of the Exchange Act to the extent not publicly available on the Commission’s website. 

In connection with a Shelf Registration Statement, each Holder agrees by acquisition of a Transfer Restricted Security that, upon receipt of
any notice from the Company of the existence of any fact of the kind described in Section 6(c)(iii)(D) hereof, such Holder will forthwith discontinue disposition of Transfer Restricted Securities pursuant to the applicable Shelf Registration
Statement until such Holder’s receipt of the copies of the supplemented or amended 

  
 14 

 
Prospectus contemplated by Section 6(c)(xv) hereof, or until it is advised in writing (the “Advice”) by the Company that the use of the Prospectus may be resumed, and has received
copies of any additional or supplemental filings that are incorporated by reference in the Prospectus. If so directed by the Company, each Holder will deliver to the Company (at the Company’s expense) all copies, other than permanent file
copies then in such Holder’s possession, of the Prospectus covering such Transfer Restricted Securities that was current at the time of receipt of such notice. In the event the Company shall give any such notice, the time period regarding the
effectiveness of such Shelf Registration Statement set forth in Section 3 or 4 hereof, as applicable, shall be extended by the number of days during the period from and including the date of the giving of such notice pursuant to
Section 6(c)(iii)(D) hereof to and including the date when each selling Holder covered by such Shelf Registration Statement shall have received the copies of the supplemented or amended Prospectus contemplated by Section 6(c)(xv) hereof or
shall have received the Advice; provided, however, that no such extension shall be taken into account in determining whether Additional Interest is due pursuant to Section 5 hereof or the amount of such Additional Interest, it being
agreed that the Company’s option to suspend use of a Shelf Registration Statement for more than 60 consecutive days pursuant to this paragraph shall be treated as a Registration Default for purposes of Section 5 hereof. 

SECTION 7 
 REGISTRATION

 (a) All expenses incident to the Company’s and the Guarantors’ performance of or compliance with this Agreement
will be borne by the Company and the Guarantors, jointly and severally, regardless of whether a Registration Statement becomes effective, including, without limitation: (i) all registration and filing fees and expenses (including filings made

SECTION 8 

INDEMNIFICATION 
 (a) The
Company and the Guarantors, jointly and severally, agree to indemnify and hold harmless (i) each Holder and (ii) each Person, if any, who controls (within the meaning of Section 15 of the Securities Act or Section 20 of the
Exchange Act) any Holder (any of the Persons referred to in this clause (ii) being hereinafter referred to as a “controlling person”) and (iii) the respective officers, directors, partners, employees, representatives and agents
of any Holder or any controlling person (any Person referred to in clause (i), (ii) or (iii) may hereinafter be referred to as an “Indemnified Holder”), to the fullest extent lawful, from and against any and all losses, claims,
damages, liabilities, judgments, actions and expenses (including, without limitation, and as incurred, reimbursement of all reasonable costs of investigating, preparing, pursuing, settling, compromising, paying or defending any claim or action, or
any investigation or proceeding by any governmental agency or body, commenced or threatened, including the reasonable fees and expenses of counsel to any Indemnified Holder), joint or several, directly or indirectly caused by, related to, based
upon, arising out of or in connection with (1) any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement (or any amendment or supplement thereto), or any omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or (2) any untrue statement or alleged untrue statement of a material fact contained in any Prospectus (or any amendment or
supplement thereto), or any omission or alleged omission to state therein a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case except insofar as such
losses, claims, damages, liabilities or expenses are caused by an untrue statement or omission or alleged untrue statement or omission that is made in reliance upon and in conformity with information relating to any of the Holders furnished in
writing to the Company by any of the Holders expressly for use therein. This indemnity agreement shall be in addition to any liability which the Company or the Guarantors may otherwise have. 

In case any action or proceeding (including any governmental or regulatory investigation or proceeding) shall be brought or asserted against
any of the Indemnified Holders with respect to which indemnity may be sought against the Company or the Guarantors, such Indemnified Holder (or the Indemnified Holder controlled by such controlling person) shall promptly notify the Company and the
Guarantors in writing; provided, however, that the failure to give such notice shall not relieve the Company or the Guarantors of their respective obligations pursuant to this Agreement. Such Indemnified Holder shall have the right to employ
its own counsel in any such action and the fees and expenses of such counsel shall be paid, as incurred, by the Company and the Guarantors (regardless of whether it is ultimately determined that an Indemnified Holder is not entitled to
indemnification hereunder). The Company and the Guarantors shall not, in connection with any one such action or proceeding or separate but substantially similar or related actions or proceedings in the same jurisdiction arising out of the same
general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of 

  
 16 

 
attorneys (in addition to any local counsel) at any time for such Indemnified Holders, which firm shall be designated by the Holders. The Company and the Guarantors shall be liable for any
settlement of any such action or proceeding effected with the Company’s and the Guarantors’ prior written consent, which consent shall not be withheld unreasonably, and the Company and the Guarantors agree to indemnify and hold harmless
any Indemnified Holder from and against any loss, claim, damage, liability or expense by reason of any settlement of any action effected with the written consent of the Company and the Guarantors. The Company and the Guarantors shall not, without
the prior written consent of each Indemnified Holder, settle or compromise or consent to the entry of judgment in or otherwise seek to terminate any pending or threatened action, claim, litigation or proceeding in respect of which indemnification or
contribution may be sought hereunder (whether or not any Indemnified Holder is a party thereto), unless such settlement, compromise, consent or termination (i) includes an unconditional release of each Indemnified Holder from all liability
arising out of such action, claim, litigation or proceeding and (ii) does not include any statements as to or any findings of fault, culpability or failure to act by or on behalf of any Indemnified Holder. 

(b) Each Holder of Transfer Restricted Securities agrees, severally and not jointly, to indemnify and hold harmless the Company, the
Guarantors and their respective directors and officers who sign a Registration Statement, and any Person controlling (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) the Company or the Guarantors,
and the respective officers, directors, partners, employees, representatives and agents of each such Person, to the same extent as the foregoing indemnity from the Company and the Guarantors to each of the Indemnified Holders, but only with respect
to claims and actions based on information relating to such Holder furnished in writing by such Holder expressly for use in any Registration Statement. In case any action or proceeding shall be brought against the Company, the Guarantors or their
respective directors or officers or any such controlling person in respect of which indemnity may be sought against a Holder of Transfer Restricted Securities, such Holder shall have the rights and duties given the Company and the Guarantors, and
the Company, the Guarantors, their respective directors and officers and such controlling person shall have the rights and duties given to each Holder by the preceding paragraph. 

(c) If the indemnification provided for in this Section 8 is unavailable to an indemnified party under Section 8(a) or
(b) hereof (other than by reason of exceptions provided in those Sections) in respect of any losses, claims, damages, liabilities, judgments, actions or expenses referred to therein, then each applicable indemnifying party, in lieu of
indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative benefits
received by the Company and the Guarantors, on the one hand, and the Holders, on the other hand, from the Initial Placement (which in the case of the Company and the Guarantors shall be deemed to be equal to the total gross proceeds to the Company
and the Guarantors from the Initial Placement), the amount of Additional Interest which did not become payable as a result of the filing of the Registration Statement resulting in such losses, claims, damages, liabilities, judgments actions or
expenses, and such Registration Statement, or if such allocation is not permitted by applicable law, the relative fault of the Company and the Guarantors, on the one hand, and of the Holders, on the other hand, in connection with the statements or
omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative fault 

  
 17 

 
of the Company and the Guarantors on the one hand and of the Indemnified Holder on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company and the Guarantors, on the one hand, or by the Indemnified Holders, on the other hand, and the parties’
relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be
deemed to include, subject to the limitations set forth in the second paragraph of Section 8(a) hereof, any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim.

 The Company, the Guarantors and each Holder of Transfer Restricted Securities agree that it would not be just and equitable if
contribution pursuant to this Section 8(c) were determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations
referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or expenses referred to in the immediately preceding paragraph shall be deemed to include,
subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8, none
of the Holders (and their related Indemnified Holders) shall be required to contribute, in the aggregate, any amount in excess of the amount by which the total discount received by such Holder with respect to the Initial Securities exceeds the
amount of any damages which such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The Holders’ obligations to contribute pursuant to this Section 8(c) are several in
proportion to the respective principal amount of Initial Securities held by each of the Holders hereunder and not joint. 
 SECTION 9

 RULE 144A 
 The
Company and the Guarantors hereby agree with each Holder, that, at any time when the Company is not subject to Section 13 or 15(d) of the Exchange Act and for so long as any Transfer Restricted Securities remain outstanding, they shall make
available to any Holder or beneficial owner of Transfer Restricted Securities in connection with any sale thereof and any prospective purchaser of such Transfer Restricted Securities from such Holder or beneficial owner, the information required by
Rule 144A(d)(4) under the Securities Act in order to permit resales of such Transfer Restricted Securities pursuant to Rule 144A under the Securities Act. 

SECTION 10 

PARTICIPATION IN UNDERWRITTEN REGISTRATIONS 

No Holder may participate in any Underwritten Registration hereunder unless such Holder (a) agrees to sell such Holder’s Transfer
Restricted Securities on the basis provided in 

  
 18 

 
any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements and (b) completes and executes all reasonable questionnaires, powers of attorney,
indemnities, underwriting agreements, lock-up letters and other documents required under the terms of such underwriting arrangements. 

SECTION 11 
 SELECTION OF
UNDERWRITERS 
 The Holders of Transfer Restricted Securities covered by the Shelf Registration Statement who desire to do so may sell
such Transfer Restricted Securities in an Underwritten Offering. In any such Underwritten Offering, the investment banker(s) and managing underwriter(s) that will administer such offering will be selected by the Holders of a majority in aggregate
principal amount of the Transfer Restricted Securities included in such offering; provided, however, that such investment banker(s) and managing underwriter(s) must be reasonably satisfactory to the Company. 

SECTION 12 

MISCELLANEOUS 
 (a)
Remedies. The Company and the Guarantors hereby agree that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by them of the provisions of this Agreement and hereby agree to waive the defense in
any action for specific performance that a remedy at law would be adequate. 
 (b) No Inconsistent Agreements. The Company and the
Guarantors will not, on or after the date of this Agreement, enter into any agreement with respect to their securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof.
The rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of the Company’s or any Guarantors’ securities under any agreement in effect on the date hereof.

 (c) Adjustments Affecting the Securities. The Company and the Guarantors will not take any action, or permit any change within
their control to occur, with respect to the Securities that would materially and adversely affect the ability of the Holders to Consummate any Exchange Offer. 

(d) Amendments and Waivers. The provisions of this Agreement may not be amended, modified or supplemented, and waivers or consents to
or departures from the provisions hereof may not be given unless the Company has (i) in the case of Section 5 hereof and this Section 12(d)(i), obtained the consent of Holders of all outstanding Transfer Restricted Securities and
(ii) in the case of all other provisions hereof, obtained the consent of Holders of a majority of the outstanding principal amount of Transfer Restricted Securities (excluding any Transfer Restricted Securities held by the Company or its
Affiliates). Notwithstanding the foregoing, a waiver or consent to departure from the provisions hereof that relates exclusively to the rights of Holders whose securities are being tendered pursuant to an Exchange Offer and that does not affect
directly or indirectly the rights of other Holders whose securities are not being tendered pursuant to such Exchange Offer may be given by the Holders of a majority of the 

  
 19 

 
outstanding principal amount of Transfer Restricted Securities being tendered or registered; provided, however, that, with respect to any matter that directly or indirectly affects the
rights of any Initial Purchaser hereunder, the Company shall obtain the written consent of each such Initial Purchaser with respect to which such amendment, qualification, supplement, waiver, consent or departure is to be effective. 

(e) Notices. All notices and other communications provided for or permitted hereunder shall be made in writing in the English language

ARTICLE III 
 PENSION,
RETIREMENT AND DEFERRED COMPENSATION PLANS 
 3.01 Defined Contribution Plans. 

(a) Establishment of the Columbia Retirement Savings Plan. Effective on or before the Distribution Date, Columbia shall
adopt, establish and maintain a 401(k) profit sharing plan and trust for the benefit of employees of the Columbia Parties that is substantially similar to the NiSource RSP and is intended to be qualified under Section 401(a) of the Code and
exempt from federal income tax under Section 501(a) of the Code (the “Columbia RSP”). As soon as practicable after the adoption of the Columbia RSP, or as otherwise required under Revenue Procedure 2007-44, Columbia
shall submit an application to the IRS for a determination that the Columbia RSP is qualified under Section 401(a) of the Code and that the related Columbia RSP Trust is exempt from federal income tax under Section 501(a) of the Code, and
shall take any actions not inconsistent with Columbia’s other general commitments contained in this Agreement and make any amendments necessary to receive such determination. As of the Distribution Date, each Business Employee employed by the
Columbia Parties (and any survivor or beneficiary of a Deceased Business Employee who is entitled to a benefit under the NiSource RSP immediately prior to the Distribution Date) shall be eligible to participate in the Columbia RSP, which shall
recognize the service of such Business Employee with NiSource and its Subsidiaries in accordance with Section 7.04. 

(b) Transfer of Assets from NiSource, Inc. Retirement Savings Plan. On or as soon as administratively practicable after
the Distribution Date, NiSource shall cause the NiSource RSP Trust to transfer to the Columbia RSP Trust assets having a value as of the applicable valuation date that is equal to the value of the account balances of, and accrued liabilities
(including any outstanding loan balances) with respect to, all Business Employees and all survivors and beneficiaries of all Deceased Business Employees with an account balance under the NiSource RSP as of such valuation date. “Accrued
liabilities” for these purposes shall include employer matching contributions and nondiscretionary employer profit sharing contributions deposited to the NiSource RSP Trust on a per payroll basis for any Business Employee that was accrued prior
to the transfer of assets from the NiSource RSP Trust to the Columbia RSP Trust. Notwithstanding the foregoing, with respect to any discretionary profit sharing contributions payable to Business Employees for the 2015 calendar year and to be paid
after the end of the 2015 calendar year, (i) NiSource and Columbia shall determine the amount of any employer profit sharing contribution, including the identification of Business Employees who satisfy the eligibility requirements for such
profit sharing contribution under the Columbia RSP as of December 31, 2015 and who would have satisfied such requirements under the NiSource RSP but for the Distribution, (ii) NiSource shall make a cash payment to Columbia equal to the
portion of such 

  
 7 

 
contribution that is associated with service for and compensation earned prior to the date of the Distribution, with such payment to be made on or before the due date for such contribution under
the terms of the Code and the Columbia RSP and (iii) Columbia shall contribute to the Columbia RSP the full amount of such contribution. Columbia shall be solely responsible for and shall determine the amount of any discretionary profit sharing
contribution payable to these Business Employees that is associated with service for and compensation earned from Columbia or an Affiliate for the period beginning on the Distribution Date and ending on December 31, 2015. In addition, on or as
soon as administratively practicable after the Distribution Date, a pro rata share of all unallocated amounts (including but not limited to any forfeiture accounts, revenue sharing credit accounts or other unallocated accounts held under the
NiSource RSP immediately prior to the Distribution Date) shall be transferred from the NiSource RSP Trust to the Columbia RSP Trust, determined based upon the ratio of the number of all Business Employees actively participating in the NiSource RSP
immediately prior to the Distribution Date to the number of all employees actively participating in the NiSource RSP immediately prior to the Distribution Date. Assets transferred pursuant to this paragraph shall be in cash or in kind, including
shares of securities, promissory notes evidencing outstanding plan loans, NiSource Shares or Columbia Shares, and such transfer shall be made in accordance with Section 414(l) of the Code. Liabilities under any qualified domestic relations
orders (as defined in Section 414(p) of the Code) received with respect to any accounts transferred to the Columbia RSP shall be transferred to and assumed by the Columbia RSP at the time such assets attributable to such accounts are
transferred. NiSource shall transfer to Columbia, and Columbia shall accept any promissory notes, including outstanding loan balances, of Business Employees in the NiSource RSP, and Columbia shall continue to process any plan loans transferred from
the NiSource RSP to the Columbia RSP. All beneficiary designations made by Business Employees and by survivors and beneficiaries of Deceased Business Employees under the NiSource RSP shall, to the extent applicable, be transferred to, and be in full
force and effect under, the Columbia RSP until such beneficiary designations are subsequently replaced or revoked by the Business Employee (or the survivor or beneficiary of the Deceased Business Employee) who made the beneficiary designation (or
his legally recognized agent). Except as noted above with respect to profit sharing contribution liabilities relating to 2015, on and after the Distribution Date, Columbia shall assume and thereafter be solely responsible for all then existing and
future employer liabilities related to such Business Employees and survivors and beneficiaries of Deceased Business Employees under the Columbia RSP and the administration thereof and the NiSource Parties shall have no liability whatsoever therefor.

 (c) Liquidation of Company Stock Funds. Subject to the fiduciary and other requirements of ERISA, and any other
applicable Laws, NiSource shall take such actions as are reasonably necessary to ensure that any liquidation of Columbia Shares held in the NiSource RSP after the Distribution Date is orderly and periodic. Subject to the exercise of its fiduciary
duties or other requirements of ERISA and any other applicable Laws, as soon as administratively practicable after the Distribution Date, NiSource shall permit participants in the NiSource RSP to transfer the investment of their plan accounts out of
the Columbia Share fund maintained under such plan and shall prohibit participants from transferring the investment of their plan accounts or electing the investment of new contributions into such Columbia Share fund, but shall not

  
 8 

 
otherwise require the liquidation of any Columbia Shares from the NiSource RSP until the first anniversary of the Distribution Date or other such date determined by the NiSource Benefits
Committee as the named fiduciary for the NiSource RSP. Notwithstanding the foregoing, nothing herein shall require the liquidation of Columbia Shares from the NiSource RSP. Subject to the fiduciary and other requirements of ERISA, and any other
applicable Laws, Columbia shall take such actions as are reasonably necessary to ensure that any liquidation of NiSource Shares held in the Columbia RSP is orderly and periodic. Subject to the exercise of its fiduciary duties or other requirements
of ERISA and any other applicable Laws, as soon as administratively practicable after the Distribution Date, Columbia shall permit participants in the Columbia RSP to transfer the investment of their plan accounts out of the NiSource Share fund
maintained under such plan and shall prohibit participants from transferring the investment of their plan accounts or electing the investment of new contributions into such NiSource Share fund, but shall not otherwise require the liquidation of any
NiSource Shares from the Columbia RSP until the first anniversary of the Distribution Date or other such date determined by the named fiduciary for the Columbia RSP. Notwithstanding the foregoing, nothing herein shall require the liquidation of
NiSource Shares from the Columbia RSP. 
 3.02 Defined Benefit Pension Plans.  

(a) Establishment of Columbia Pension Plan. Effective on or before the Distribution Date, Columbia shall adopt,
establish and maintain a Pension Plan and a trust for the benefit of employees of the Columbia Parties (the “Columbia Pension Plan”). Whether in a unified plan document or multiple plan documents that make up a single Pension
Plan, the Columbia Pension Plan will be substantially similar to each applicable NiSource Pension Plan that has a portion of assets and liabilities transferred pursuant to Section 3.02(b), and to the related trust(s). The Columbia Pension Plan
is intended to be qualified under Section 401(a) of the Code and exempt from federal income tax under Section 501(a) of the Code. As soon as practicable after the adoption of the Columbia Pension Plan and trust, or as otherwise required
under Revenue Procedure 2007-44, Columbia shall submit an application to the IRS for a determination that the Columbia Pension Plan is qualified under Section 401(a) of the Code and that the related trust is exempt from federal income tax under
Section 501(a) of the Code, and shall take any actions not inconsistent with Columbia’s other general commitments contained in this Agreement and make any amendments necessary to receive such determination. 

(b) Transfer of Assets and Liabilities. As of the Distribution Date, the Columbia Pension Plan shall assume all
liabilities with respect to all Business Employees under the NiSource Pension Plans (and any survivor or beneficiary of a Deceased Business Employee who is entitled to a benefit under the NiSource Pension Plans immediately prior to the Distribution
Date) and neither NiSource nor any of its Affiliates shall retain any such liabilities. On the Distribution Date, NiSource shall cause to be transferred from the NiSource Master Retirement Trust (the “NiSource DB Master
Trust”) to the trust established for the Columbia Pension Plan (the “Columbia Pension Trust”) an initial amount of assets (the “Initial Transfer Amount”) in funds that are immediately
available funds under the NiSource DB Master Trust, which such amount 

  
 9 

 
shall be equal to 75% of the amount the actuary engaged by the NiSource Pension Plans determines in good faith to be a reasonable estimate of the amount of assets to be transferred as of the
Distribution Date for all Business Employees (and all survivors and beneficiaries of Deceased Business Employees) with accrued benefits under the NiSource Pension Plans in accordance with Section 414(l) of the Code and Section 4044 of
ERISA. As soon as administratively practicable after the Distribution Date, the actuary engaged by the NiSource Pension Plans shall determine the final amount of assets to be transferred as of the Distribution Date for all Business Employees (and
all survivors and beneficiaries of Deceased Business Employees) with accrued benefits under the NiSource Pension Plans in accordance with Section 414(l) of the Code and Section 4044 of ERISA (the “Final Transfer
Amount”). As soon as administratively practicable after the later to occur of (i) the date the Final Transfer Amount is determined and (ii) the expiration of the waiting period prescribed by Section 6058(b) of the Code,
the NiSource Parties shall direct the trustee of the NiSource DB Master Trust to transfer the Final Transfer Amount in funds that are immediately available funds under the NiSource DB Master Trust to the trustee of the Columbia Pension
Trust. The Final Transfer Amount shall be reduced (i) by the Initial Transfer Amount, (ii) as necessary to reflect benefit payments made from the NiSource DB Master Trust on behalf of any Business Employees (or any survivors or
beneficiaries of Deceased Business Employees), which such payments are effective as of the Distribution Date or any other date between the Distribution Date and the Final Transfer Date, (iii) by any administrative expenses paid from the
NiSource DB Master Trust prior to the Final Transfer Date in preparation for the administration of the Columbia Pension Plan and the transfer of the Final Transfer Amount to the Columbia Pension Trust and (iv) by the pro-rata portion of monthly
investment expenses incurred by the NiSource Pension Plans attributable to the Final Transfer Amount for the period beginning on the Distribution Date and ending on the Final Transfer Date. From the actual date of delivery of the Initial Transfer
Amount on the Distribution Date until the actual date of delivery of the Final Transfer Amount (the “Final Transfer Date”), the trustee of the NiSource DB Master Trust shall hold the Final Transfer Amount under the NiSource
Pension Plans and the Final Transfer Amount shall be credited with earnings, from the Distribution Date to the Final Transfer Date, at a rate equal to the actual rate of return for the investments in the NiSource DB Master Trust for the period
beginning on the Distribution Date and ending on the Final Transfer Date. Further, liabilities under any qualified domestic relations orders (as defined in Section 414(p) of the Code) received with regard to any benefits for such Business
Employees shall be transferred to and assumed by the Columbia Pension Plan as of the Distribution Date. All beneficiary designations made by Business Employees and by survivors and beneficiaries of Deceased Business Employees under the NiSource
Pension Plans shall, to the extent applicable, be transferred to, and be in full force and effect under, the Columbia Pension Plan until such beneficiary designations are replaced or revoked by the Business Employee (or the survivor or beneficiary
of the Deceased Business Employee) who made the beneficiary designation (or his legally recognized agent). 
 3.03 Nonqualified Deferred
Compensation Plans. Effective on or before the Distribution Date, Columbia shall adopt, establish and maintain nonqualified deferred compensation plans for the benefit of employees of the Columbia Parties (the “Columbia Deferred
Compensation Plans”) and shall establish one or more grantor trusts to be a source of providing benefits thereunder (the “Columbia Rabbi Trusts”) that in each case shall be

  
 10 

 
substantially similar to the NiSource Deferred Compensation Plans and the grantor trusts maintained by NiSource with respect to the NiSource Deferred Compensation Plans (the “NiSource
Rabbi Trusts”). As of the Distribution Date, the Columbia Parties shall assume and thereafter be solely responsible for all existing and future liabilities relating to Business Employees’ (and Deceased Business Employee
survivors’ and beneficiaries’) (a) benefits accrued under the NiSource Deferred Compensation Plans prior to the Distribution Date and (b) benefits that accrue under the Columbia Deferred Compensation Plans on and after the
Distribution Date. All beneficiary designations made by Business Employees and by survivors and beneficiaries of Deceased Business Employees under the NiSource Deferred Compensation Plans shall, to the extent applicable, be transferred to, and be in
full force and effect under, the Columbia Deferred Compensation Plans until such beneficiary designations are replaced or revoked by the Business Employee (or the survivor or beneficiary of the Deceased Business Employee) who made the beneficiary
designation. Following the Distribution Date, the NiSource Parties shall have no liability or obligation with respect to the benefits accrued by such Business Employees or by such survivors or beneficiaries of Deceased Business Employees under any
of the NiSource Deferred Compensation Plans or with respect to any benefits accrued under the Columbia Deferred Compensation Plans. As soon as administratively practicable after the Distribution Date, NiSource shall cause the NiSource Rabbi Trusts
to transfer to the Columbia Rabbi Trusts cash, life insurance policies or other assets having an aggregate fair market value equal to (i) the aggregate fair market value of all assets held in the NiSource Rabbi Trusts as of the Distribution
Date multiplied by (ii) a percentage, the numerator of which shall be the lump sum present value of the benefits assumed by the Columbia Deferred Compensation Plans pursuant to this Section 3.03 and the denominator of which shall be the
lump sum present value of all benefits accrued under the NiSource Deferred Compensation Plans immediately prior to the Distribution Date.

Dependent, the Deceased Business Employee, prior to the Distribution Date with a NiSource Party shall be treated as service with a Columbia Party. Columbia shall cause each Columbia Welfare Plan to waive any waiting periods, evidence of insurability
requirements, and the application of any preexisting condition limitations with respect to each Business Employee (and, if applicable, such Business Employee’s participating spouse and/or dependents) and Surviving Dependent. Columbia shall

credited or applied to the annual or lifetime benefit limitation for such Business Employee (and, if applicable, such Business Employee’s participating spouse and/or dependents) or Surviving Dependent under the corresponding Columbia Welfare

such beneficiary designations are replaced or revoked by the Business Employee or Surviving Dependent who made the beneficiary designation. With respect to each Business Employee and Surviving Dependent, each Columbia Retiree Welfare Plan shall
provide that for purposes of determining eligibility to participate, vesting and entitlement to benefits, service by the Business Employee or, in the case of a Surviving Dependent, the Deceased Business Employee, prior to the Distribution Date with

limitations with respect to each Business Employee (and, if applicable, such Business Employee’s participating spouse and/or dependents) and Surviving Dependent. Columbia shall cause each Columbia Retiree Welfare Plan to honor any deductible,

appropriate, including approval of the provisions of this Section 6.02(a) by the Columbia Board and the NiSource Compensation Committee pursuant to the terms of the applicable NiSource Stock Plan, the applicable Columbia Stock Plan and this
Agreement, so that each NiSource RSU Award held at the close of business on the Distribution Date by any Columbia Employee shall be replaced with a substitute Columbia restricted stock unit award granted under the applicable Columbia Stock Plan (a
“Substitute Columbia RSU Award”). The number of Columbia restricted stock units subject to the Substitute Columbia RSU Award will be equal to the number of NiSource restricted stock units subject to the NiSource RSU Award
held by the participant at the close of business on the Distribution Date multiplied by a fraction, the numerator of which is the NiSource Pre-Distribution Stock Price, and the denominator of which is the Columbia Post-Distribution Stock Price. Each
Substitute Columbia RSU Award shall vest and be payable based on the holder’s employment or service with the Columbia Parties. Each Substitute Columbia RSU Award shall have substantially the same terms and conditions as the corresponding
NiSource RSU Award, except as provided herein. 
 (b) RSUs Held by Columbia Non-Employee Directors. NiSource

Director”) shall be treated as provided in clause (1) or (2) of this Section 6.02(b), as applicable. 

(1) Unvested NiSource RSUs. Each NiSource RSU Award held at the close of business on the Distribution Date by a Columbia
Non-Employee Director that is not yet vested as of the Distribution Date shall be replaced with a Substitute Columbia RSU Award. The number of Columbia restricted stock units subject to the Substitute Columbia RSU Award will be equal to the number
of NiSource restricted stock units subject to the NiSource RSU Award held by the Columbia Non-Employee Director at the close of business on the Distribution Date multiplied by a fraction, the numerator of which is the NiSource Pre-Distribution Stock

an additional Columbia restricted stock unit award granted under the applicable Columbia Stock Plan (a “Supplemental Columbia RSU Award”). The Supplemental Columbia RSU
Awards shall be fully and immediately vested as of the Distribution Date and shall be payable at the same time and under substantially the same terms and conditions as the related vested NiSource RSU Award. The number of Columbia restricted stock
units subject to the Supplemental Columbia RSU Award shall be equal to the number of shares of Columbia stock that the Columbia Non-Employee Director would have received pursuant to the Distribution Agreement if the Columbia Non-Employee Director

Columbia Non-Employee Director or non-employee director of NiSource shall be adjusted (an “Adjusted NiSource RSU Award”). The number of NiSource restricted stock units subject to the Adjusted NiSource RSU Award will be equal
to the number of NiSource restricted stock units subject to the NiSource RSU Award held by the holder at the close of business on the Distribution Date multiplied by a fraction, the numerator of which is the NiSource Pre-Distribution Stock Price,
and the denominator of which is the NiSource Post-Distribution Stock Price. Each Adjusted NiSource RSU Award shall have substantially the same terms and conditions as the corresponding NiSource RSU Award, except as provided herein.

on the Distribution Date multiplied by a fraction, the numerator of which is the NiSource Pre-Distribution Stock Price, and the denominator of which is the NiSource Post-Distribution Stock Price. Each Adjusted NiSource RSU Award shall have

Columbia RSU Award. The Supplemental Columbia RSU Awards shall be fully and immediately vested as of the Distribution Date and shall be payable at the same time and under substantially the same terms and conditions as the related vested NiSource RSU
Award. The number of Columbia restricted stock units subject to the Supplemental Columbia RSU Award shall be equal to the number of shares of Columbia stock that the NiSource Non-Employee Director would have received pursuant to the Distribution
Agreement if the NiSource Non-Employee Director owned the shares of NiSource stock subject to the vested NiSource RSU Award.

Performance Share Awards.

Agreement, so that each NiSource Performance Share Award granted under a NiSource Stock Plan in 2013 and held at the close of business on the Distribution Date by any Columbia Employee will be replaced with a Substitute Columbia RSU Award granted
under the applicable Columbia Plan. The number of NiSource Shares earned pursuant to the NiSource Performance Share Award shall be determined by the NiSource Compensation Committee based on performance results through the Distribution Date. The
number of such NiSource Shares that are earned shall then be converted into a Substitute Columbia RSU Award by multiplying the number of such earned NiSource Shares by a fraction, the numerator of which is the NiSource Pre-Distribution Stock Price
and the denominator of which is the Columbia Post-Distribution Stock Price. Each Substitute Columbia RSU Award shall continue to vest based on the holder’s service with the Columbia Parties, and shall have the same terms and conditions as the

Employee will be replaced with a Substitute Columbia RSU Award granted under the applicable Columbia Stock Plan. With respect to 50% of such NiSource Performance Share Award, the number of
NiSource Shares that are deemed to have been earned as of the Distribution Date shall be equal to 50% of the target number of NiSource Shares subject to such NiSource Performance Share Award. With respect to the remaining 50% of such NiSource
Performance Share Award, the number of NiSource Shares earned shall be determined by the NiSource Compensation Committee based on performance results through the Distribution Date. The number of such NiSource Shares that are earned or deemed to have

Share Award granted under a NiSource Stock Plan in 2013 and held at the close of business on the Distribution Date by any person who is not a Columbia Employee will be adjusted and paid under the terms of the NiSource Stock Plan and applicable award
agreement. The number of NiSource Shares earned pursuant to the NiSource Performance Share Award shall be determined by the NiSource Compensation Committee based on performance results through the Distribution Date. The number of such NiSource

 20

(a) Phantom Stock Units Held by Columbia Employees. NiSource and Columbia shall take any and all action as shall
be necessary or appropriate, so that each NiSource Phantom Stock Unit Award held at the close of business on the Distribution Date by any Columbia Employee shall be replaced with a substitute Columbia phantom stock unit award granted under the

 8.10 Amendment. This Agreement shall not be amended, modified or supplemented except by a
written instrument signed by an authorized representative of each of NiSource and Columbia. 
 8.11 Waiver. Any term or provision of
this Agreement may be waived, or the time for its performance may be extended, by the party or parties entitled to the benefit thereof. Any such waiver shall be validly and sufficiently given for the purposes of this Agreement if, as to any party,
it is in writing signed by an authorized representative of such party. The failure of either party to enforce at any time any provision of this Agreement shall not be construed to be a waiver of such provision, or in any way to affect the validity
of this Agreement or any part hereof or the right of any party thereafter to enforce each and every such provision. No waiver of any breach of this Agreement shall be held to constitute a waiver of any other or subsequent breach. 

8.12 Partial Invalidity. Wherever possible, each provision hereof shall be construed in a manner as to be effective and valid under
applicable Law, but in case any one or more of the provisions contained herein shall, for any reason, be held to be invalid, illegal or unenforceable in any respect, such provision shall be ineffective to the extent, but only to the extent of such
invalidity, illegality or unenforceability without invalidating the remainder of such invalid, illegal or unenforceable provision or provisions or any other provision hereof, unless such a construction would be unreasonable. 

8.13 Execution in Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original instrument,
but both of which shall be considered one and the same agreement, and shall become binding when the counterparts have been signed by and delivered to each of the parties hereto. Delivery of an executed counterpart of a signature page to this
Agreement by facsimile or .pdf shall be as effective as delivery of a manually executed counterpart to this Agreement. 
 8.14 Successors
and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their successors and permitted assigns; provided, however, that the rights and obligations of either party under this Agreement shall not
be assignable by such party without the prior written consent of the other party. The successors and permitted assigns hereunder shall include any permitted assignee as well as the successors in interest to such permitted assignee (whether by
merger, liquidation (including successive mergers or liquidations) or otherwise). 
 8.15 No Third-Party Beneficiaries. No Business
Employee or other current or former employee of the NiSource Parties or Columbia Parties (or his/her spouse, dependent or beneficiary), or any other person not a party to this Agreement, shall be entitled to assert any claim hereunder. The
provisions of this Agreement are solely for the benefit of the parties hereto and their respective successors and permitted assigns, and nothing herein express or implied shall give or be construed to give to any other Person any legal or equitable
rights hereunder. 
 8.16 Notices. All notices or other communications under this Agreement shall be in writing and shall be deemed
to be duly given when delivered or mailed in accordance with the terms of Section 10.11 of the Distribution Agreement.

 8.17 Performance. NiSource will cause to be performed and hereby guarantees the
performance of all actions, agreements and obligations set forth herein to be performed by any NiSource Party. Columbia will cause to be performed and hereby guarantees the performance of all actions, agreements and obligations set forth herein to
be performed by any Columbia Party. This Agreement is being entered into by NiSource and Columbia on behalf of themselves and the members of their respective groups (the NiSource Parties and the Columbia Parties). This Agreement shall constitute a
direct obligation of each such entity and shall be deemed to have been readopted and affirmed on behalf of any Person that becomes a Subsidiary of NiSource or Columbia on and after the Effective Time. 

8.18 Force Majeure. No party shall be deemed in default of this Agreement to the extent that any delay or failure in the performance of
its obligations under this Agreement results from any cause beyond its reasonable control and without its fault or negligence, including acts of God, acts of civil or military authority, embargoes, acts of terrorism, epidemics, war, riots,
insurrections, fires, explosions, earthquakes, floods, unusually severe weather conditions, labor problems or unavailability of parts, or, in the case of computer systems, any failure in electrical or air conditioning equipment. In the event of any
such excused delay, the time for performance shall be extended for a period equal to the time lost by reason of the delay. A party claiming the benefit of this provision shall, as soon as reasonably practicable after the occurrence of any such
event, (a) notify the other party of the nature and extent of any such force majeure condition and (b) use due diligence to remove any such causes and resume performance under this Agreement as soon as reasonably feasible. 

8.19 No Public Announcement. Neither party hereto shall, without the prior written approval of the other party, make any press release
or other public announcement concerning the transactions contemplated by this Agreement, except as and to the extent that any such party shall be so obligated by Law or the rules of any regulatory body or stock exchange, in which case the other
party shall be advised and the parties shall use their respective commercially reasonable efforts to cause a mutually agreeable release or announcement to be issued; provided, however, that the foregoing shall not preclude
communications or disclosures necessary to implement the provisions of this Agreement or to comply with the accounting and SEC disclosure obligations or the rules of any stock exchange. 

8.20 Limited Liability. Notwithstanding any other provision of this Agreement, no Person who is a stockholder, director, employee,
officer, agent or Representative of Columbia or NiSource, in such individual’s capacity as such, shall have any liability in respect of or relating to the covenants or obligations of Columbia or NiSource, as applicable, under this Agreement or
any Transaction Agreement or in respect of any certificate delivered with respect hereto or thereto, and, to the fullest extent legally permissible, each of Columbia and NiSource, for itself and its stockholders, directors, employees, officers and
Affiliates, waives and agrees not to seek to assert or enforce any such liability that any such individual otherwise might have pursuant to applicable Law. 

8.21 Effect if Distribution Does Not Occur. Notwithstanding anything in this Agreement to the contrary, if the Distribution Agreement
is terminated prior to the Distribution, this Agreement shall be of no further force and effect. 

  
 28 

 8.22 Miscellaneous. Except as otherwise expressly set forth in this Agreement, the
provisions of Article X of the Separation and Distribution Agreement shall apply mutatis mutandis to this Agreement.
