commencement of any action, such indemnified party will, if a claim in respect thereof is to be
made against the indemnifying party under subsection (a)&nbsp;or (b)&nbsp;above, notify the indemnifying
party of the commencement thereof; but the failure to notify the indemnifying party shall not
relieve it from any liability that it may have under subsection (a)&nbsp;or (b)&nbsp;above except to the
extent that it has been materially prejudiced through the forfeiture of substantive rights or
defenses by such failure; and provided further that the failure to notify the indemnifying party
shall not relieve it from any liability which it may have to any indemnified party otherwise than
under subsection (a)&nbsp;or (b)&nbsp;above. In case any such action is brought against any indemnified
party and it notifies the indemnifying party of the commencement thereof, the indemnifying party
will be entitled to participate therein and, to the extent that it may wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to
such indemnified party (who shall not, except with the consent of the indemnified party, be counsel
to the indemnifying party), and after notice from the indemnifying party to such indemnified party
of its election so to assume the defense thereof, the indemnifying party will not be liable to such
indemnified party under this Section for any legal or other expenses subsequently incurred by such
indemnified party in connection with the defense thereof other than reasonable costs of
investigation. No indemnifying party shall, without the prior written consent of the indemnified
party, effect any settlement of any pending or threatened action in respect of which any
indemnified party is or could have been a party and indemnity could have been sought hereunder by
such indemnified party unless such settlement (i)&nbsp;includes an unconditional release of such
indemnified party from all liability on any claims that are the subject matter of such action and
(ii)&nbsp;does not include a statement as to, or an admission of, fault, culpability or a failure to act
by or on behalf of an indemnified party.

hold harmless an indemnified party under subsection (a)&nbsp;or (b)&nbsp;above, then each indemnifying party
shall contribute to the amount paid or payable by such indemnified party as a result of the losses,
claims, damages or liabilities referred to in subsection (a)&nbsp;or (b)&nbsp;above (i)&nbsp;in such proportion as
is appropriate to reflect the relative benefits received by NiSource and NiSource Finance on the
one hand and the Underwriters on the other from the offering of the Offered Securities or (ii)&nbsp;if
the allocation provided by clause (i)&nbsp;above is not permitted by applicable law, in such proportion
as is appropriate to reflect not only the relative benefits referred to in clause (i)&nbsp;above but
also the relative fault of NiSource and NiSource Finance on the one hand and the Underwriters on
the other in connection with the statements or omissions which resulted in such losses, claims,
damages or liabilities as well as any other relevant equitable considerations. The relative
benefits received by NiSource and NiSource Finance on the one hand and the Underwriters on the
other shall be deemed to be in the same proportion as the total net proceeds from the offering
(before deducting expenses) received by NiSource and NiSource Finance bear to the total
underwriting discounts and commissions received by the Underwriters. The relative fault 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 NiSource and NiSource Finance on the one hand or the Underwriters on the other and the
parties&#146; relative intent, knowledge, access to information and opportunity to correct or prevent
such untrue statement or omission. The amount paid by an indemnified party as a result of the
losses, claims, damages or liabilities referred to in the first sentence of this subsection (d)
shall be deemed to include any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending any action or claim which is the subject of
this subsection (d). Notwithstanding the provisions of this subsection (d), no Underwriter shall
be required to contribute any amount in excess of the amount by which the total price at which the
Offered Securities underwritten by it and distributed to the public were offered to the public
exceeds the amount of any damages which such Underwriter 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 Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.
The Underwriters&#146; obligations in this subsection (d)&nbsp;to contribute are several in proportion to
their respective underwriting obligations and not joint.

to purchase Offered Securities under the Terms Agreement and the aggregate principal amount (if
debt securities) or number of shares (if preferred stock or Common Stock) of Offered Securities
that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10%
of the total principal amount (if debt securities) or number of shares (if preferred stock or
Common Stock) of Offered Securities, the Lead Underwriter may make arrangements satisfactory to
NiSource and/or NiSource Finance, as the case may be, for the purchase of such Offered Securities
by other persons, including any of the Underwriters, but if no such arrangements are made by the
Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their
respective commitments under the Terms Agreement (including the provisions of this Agreement), to
purchase the Offered Securities that such defaulting Underwriters agreed but failed to purchase. If
any Underwriter or Underwriters so default and the aggregate principal amount (if debt securities)
or number of shares (if preferred stock or Common Stock) of Offered Securities with respect to
which such default or defaults occur exceeds 10% of the total principal amount (if debt securities)
or number of shares (if preferred stock or Common Stock) of Offered Securities and arrangements
satisfactory to the Lead Underwriter and NiSource and/or NiSource Finance, as the case may be, for
the purchase of such Offered Securities by other persons are not made within 36 hours after such
default, the Terms Agreement will terminate without liability on the part of any non-defaulting
Underwriter or NiSource or NiSource Finance, except as provided in Section&nbsp;9. As used in this
Agreement, the term &#147;Underwriter&#148; includes any person substituted for an Underwriter under this
Section. Nothing herein will relieve a defaulting Underwriter from liability for its default. If
the Offered Securities are debt securities or preferred stock, the respective commitments of the
several Underwriters for the purposes of this Section shall be determined without regard to
reduction in the respective Underwriters&#146; obligations to purchase the principal amounts (if debt
securities) or numbers of shares (if preferred stock) of the Offered Securities set forth opposite
their names in the Terms Agreement as a result of Delayed Delivery Contracts entered into by
NiSource and/or NiSource Finance, as the case may be.

agreements, representations, warranties and other statements of NiSource, NiSource Finance or their
respective officers and of the several Underwriters set forth in or made pursuant to the Terms
Agreement (including the provisions of this Agreement) will remain in full force and effect,
regardless of any investigation, or statement as to the results thereof, made by or on behalf of
any Underwriter, NiSource, NiSource Finance or any of their respective representatives, officers or
directors or any controlling person, and will survive delivery of and payment for the Offered
Securities. If the Terms Agreement is terminated pursuant to Section&nbsp;8 or if for any reason the
purchase of the Offered Securities by the Underwriters is not consummated, NiSource and NiSource
Finance shall remain responsible for the expenses to be paid or reimbursed by it pursuant to
Section&nbsp;5 and the respective obligations of NiSource, NiSource Finance and the Underwriters
pursuant to Section&nbsp;7 shall remain in effect. If the purchase of the Offered Securities by the
Underwriters is not consummated for any reason other than solely because of the termination of the
Terms Agreement pursuant to Section&nbsp;8 or the occurrence of any event specified in clauses (iii),
(iv), (v), (vi)&nbsp;or (vii)&nbsp;of Section&nbsp;6(c), NiSource and/or NiSource Finance will reimburse the

reasonably incurred by them in connection with the offering of the Offered Securities.

Officers&#146; Certificate of the Company dated August&nbsp;31, 2007 (the &#147;Officer&#146;s Certificate&#148;). The
terms of the Notes include those stated in the Indenture and the Officer&#146;s Certificate and those
made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. sections
77aaa-77bbbb) as in effect on the date of the Officer&#146;s Certificate (the &#147;Act&#148;). Capitalized terms
used herein and defined in the Indenture but not defined herein have the meanings ascribed thereto
in the Indenture. The Notes are subject to all such terms, and Holders of Notes are referred to
the Indenture and the Act for a statement of those terms.

covenants that limit the ability of the Company, NiSource Inc. and their Subsidiaries (other than
Utilities) to incur additional indebtedness and create liens on assets unless the total amount of
all the secured debt would not exceed 10% of Consolidated Net Tangible Assets. These covenants are
subject to important exceptions and qualifications.
