Senior Notes due 2015 (the “2015 Notes”) and a new series of Securities to be issued under the
Indenture and to be designated as the Company’s 7.50% Senior Notes due 2040 (the “2040 Notes” and
together with the 2015 Notes, the “Notes”). The 2015 Notes and the 2040 Notes shall each
constitute separate series of Securities under the Indenture. The 2015 Notes shall be substantially
in the form attached as Exhibit A-1 hereto and the 2040 Notes shall be substantially in the
form attached as Exhibit A-2 hereto, in each case with such appropriate insertions,
omissions, substitutions, notations and other variations as are required or permitted by the
Indenture, and the Notes may have such letters, numbers or other marks of identification and such
legends or endorsements placed thereon as the Company may deem appropriate or as may be required or
appropriate to comply with any laws or with any rules made pursuant thereto or with the rules of
any securities exchange or automated quotation system on which the Notes may be listed or traded,
or to conform to general usage, or as may, consistently with the Indenture, be determined by the
Officer executing such Notes, as evidenced by his execution thereof.

     The Notes shall be executed, authenticated and delivered in accordance with the provisions of,
and shall in all respects be subject to, the terms, conditions and covenants of the Original
Indenture as supplemented by this Supplemental Indenture (including the forms of Notes attached as
Exhibit A-1 and Exhibit A-2 hereto (the terms of which are incorporated in and made
a part of this Supplemental Indenture for all intents and purposes)).

SECTION 2.2 Amount.

     The aggregate principal amount of the Notes of each series that may be authenticated and
delivered pursuant hereto is unlimited. The Trustee shall initially authenticate and deliver 2015
Notes for original issue on the date hereof in an initial aggregate principal amount of
$375,000,000 and 2040 Notes for original issue on the date hereof in an initial aggregate principal
amount of $375,000,000, upon delivery to the Trustee of a Company Order for the authentication and
delivery of such Notes. The aggregate principal amount of each series of Notes to be issued
hereunder may be increased at any time hereafter and each series may be reopened for issuances of
additional Notes of such series, upon Company Order, without the consent of any Holder and without
any further supplement or amendment to the Original Indenture or this Supplemental Indenture, and
accordingly, Additional 2015 Notes and Additional 2040 Notes may be issued on any Business Day

in each case, shall be as set forth in the form of 2015 Note and the form of 2040 Note attached as

SECTION 2.6 Place of Payment.

     As long as any Notes are Outstanding, the Company shall maintain in the Borough of Manhattan,
The City of New York, an office or agency (which may be an office of the Trustee or an affiliate of
the Trustee, Registrar or co-registrar) where the principal of and any premium and interest on the
Notes shall be payable, where Notes may be surrendered for registration of transfer or for exchange
and where notices and demands to or upon the Company in respect of the Notes and this Indenture may
be served. Unless otherwise designated by the Company by written notice to the Trustee, such
office or agency shall be the Trustee’s Corporate Trust Office, as long as such office is located
in the Borough of Manhattan, The City of New York. The Company will give prompt written notice to
the Trustee of any change in the location of such office or agency. If at any time the Company
fails to maintain any such required office or agency or fails to furnish the Trustee with the
address thereof, such presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee.

     The Company may also from time to time designate one or more additional offices or agencies
where the Notes may be presented or surrendered for any or all such purposes and may from time to
time rescind such designations; provided, however, that no such designation or rescission will in
any manner relieve the Company of its obligation to maintain an office or agency in the Borough of
Manhattan, The City of New York for such purposes. The Company will give prompt written notice to
the Trustee of any such designation or rescission and of any change in the location of any such
other office or agency.

amounts of $2,000 or integral multiples of $1,000 in excess thereof, at any time or from time to
time, at the applicable Redemption Price determined as set forth in the form of 2040 Note attached

SECTION 2.9 Defeasance and Discharge; Covenant Defeasance.

     Article Thirteen of the Original Indenture (as amended and supplemented by this Supplemental
Indenture) shall apply to the Notes. Furthermore, each of the covenants set forth in Article
Four of this Supplemental Indenture, and the Event of Default specified in Section 5.1(c) of
the Original Indenture, shall, in each case, constitute “Additional Defeasible Provisions” (as such
term is used in the Original Indenture).

SECTION 2.10 Global Securities.

     The Notes of each series shall initially be issuable in whole or in part in the form of one or
more Global Securities. Such Global Securities (i) shall be deposited with, or on behalf of, The
Depository Trust Company, New York, New York, which shall act as Depositary with respect to the
Notes, (ii) shall bear the legends applicable to Global Securities set forth in Sections 2.2 and
2.4 of the Original Indenture, (iii) may be exchanged in whole or in part for Securities of such
series in definitive form upon the terms and subject to the conditions provided in Section 3.5 of
the Original Indenture and in this Supplemental Indenture and (iv) shall otherwise be subject to
the applicable provisions of the Indenture.

SECTION 2.11 Parent Guarantee.

     Article Fourteen of the Original Indenture (as amended and supplemented by this Supplemental
Indenture) shall apply to the Notes. The MLP hereby agrees that it shall be a Guarantor of each of
the 2015 Notes and the 2040 Notes in accordance with Article Fourteen of the Original Indenture.
For the purposes of this Supplemental Indenture and the Notes (including without limitation the
provisions of the Original Indenture to the extent applicable thereto), the term “Guarantor” shall
mean the MLP, and accordingly, the Parent Guarantee of the MLP shall be a Securities Guarantee with
respect to the Indenture and each of the 2015 Notes and the 2040 Notes; provided, however that such
Securities Guarantee shall not apply to any obligations under any series of Securities other than
the 2015 Notes and the 2040 Notes.

     To evidence its Parent Guarantee set forth in Article Fourteen of the Original Indenture (as
amended and supplemented by this Supplemental Indenture), the Guarantor hereby agrees that a
notation of such Parent Guarantee substantially in the form attached as Exhibit B hereto
will be endorsed by an Officer of such Guarantor on each Note authenticated and delivered by the
Trustee and that this Supplemental Indenture will be executed on behalf of such Guarantor by one of
its Officers.

     The Guarantor hereby agrees that its Parent Guarantee set forth in Article Fourteen of the
Original Indenture (as amended and supplemented by this Supplemental Indenture) will remain in full
force and effect notwithstanding any failure to endorse on each Note a notation of such Parent
Guarantee.

     If an Officer whose signature is on this Supplemental Indenture or on the Parent Guarantee no
longer holds that office at the time the Trustee authenticates the Note on which a Parent Guarantee
is endorsed, the Parent Guarantee will be valid nevertheless.

     The delivery of any Note by the Trustee, after the authentication thereof hereunder, will
constitute due delivery of the Parent Guarantee set forth in the Indenture on behalf of the
Guarantor.

ARTICLE THREE

     With respect to the Notes, the Original Indenture is hereby amended as set forth below in

     (a) The Company shall not, and shall not permit any Restricted Subsidiary to, create,
assume, incur or suffer to exist any Lien upon any Principal Property, whether owned or
leased on the Issue Date or thereafter acquired, to secure any Debt of the Company or any

however, apply to:

     (1) any Lien upon any property or assets of the Company or any Restricted

property” clause or similar term in existence on the Issue Date or any mortgage,
pledge agreement, security agreement or other similar instrument in existence on the

     (2) any Lien upon any property or assets created at the time of acquisition of
such property or assets by the Company or any Restricted Subsidiary or within one
year after such time to secure all or a portion of the purchase price for such
property or assets or Debt incurred to finance such purchase price, whether such
Debt was incurred prior to, at the time of or within one year of such acquisition;

     (3) any Lien upon any property or assets existing thereon at the time of the
acquisition thereof by the Company or any Restricted Subsidiary (regardless of
whether the obligations secured thereby are assumed by the Company or any Restricted
Subsidiary);

     (4) any Lien upon any property or assets of a Person existing thereon at the
time such Person becomes a Restricted Subsidiary by acquisition, merger or
otherwise;

     (5) the assumption by the Company or any Restricted Subsidiary of obligations
secured by any Lien existing at the time of the acquisition by the Company or any
Restricted Subsidiary of the property or assets subject to such Lien or at the time
of the acquisition of the Person that owns such property or assets;

     (6) any Lien on property to secure all or part of the cost of construction or
improvements thereon or to secure Debt incurred prior to, at the time of, or within
one year after completion of such construction or making of such improvements, to
provide funds for any such purpose;

     (7) any Lien on any oil, gas, mineral and processing and other plant properties

grant or operating or other similar agreement in connection with or incident to the
exploration, development, maintenance or operation of such properties;

     (8) any Lien arising from or in connection with a conveyance by the Company or
any Restricted Subsidiary of any production payment with respect to oil, gas,
natural gas, carbon dioxide, sulfur, helium, coal, metals, minerals, steam, timber
or other natural resources;

     (9) any Lien in favor of the Guarantor, the Company or any Subsidiary of the

     (11) any Lien upon property or assets of any foreign Restricted Subsidiary to
secure Debt of that foreign Restricted Subsidiary;

     (12) Permitted Liens;

     (13) any Lien upon any additions, improvements, replacements, repairs,
fixtures, appurtenances or component parts thereof attaching to or required to be
attached to property or assets pursuant to the terms of any mortgage, pledge
agreement, security agreement or other similar instrument, creating a Lien upon such
property or assets permitted by clauses (1) through (12) above; or

     (14) any extension, renewal, refinancing, refunding or replacement (or
successive extensions, renewals, refinancing, refundings or replacements) of any
Lien, in whole or in part, that is referred to in clauses (1) through (13) above, or
of any Debt secured thereby; provided, however, that the principal amount of Debt
secured thereby shall not exceed the greater of the principal amount of Debt so
secured at the time of such extension, renewal, refinancing, refunding or
replacement and the original principal amount of Debt so secured (plus, in each
case, the aggregate amount of premiums, other payments, costs and expenses required
to be paid or incurred in connection with such extension, renewal, refinancing,
refunding or replacement); provided, further, however, that such extension, renewal,
refinancing, refunding or replacement shall be limited to all or a part of the
property (including improvements, alterations and repairs on such property) subject
to the encumbrance so extended, renewed, refinanced, refunded or replaced (plus
improvements, alterations and repairs on such property).

Notes, the Company or any Restricted Subsidiary may create, assume, incur or suffer to exist
any Lien not excepted pursuant to clauses (1) through (14) above upon any Principal Property

Guarantee); provided that the aggregate principal amount of all such Debt then outstanding
and secured by such Lien and all similar Liens, together with all net sale proceeds from
Sale-Leaseback Transactions (excluding Sale-Leaseback Transactions permitted by paragraph
(a) in Section 10.7 of the Indenture), does not exceed 15% of Consolidated Net Tangible
Assets.

SECTION 4.2 Restriction of Sale-Leaseback Transactions.

     Section 10.7 Restriction of Sale-Leaseback Transactions.

     (a) The Company shall not, and shall not permit any Restricted Subsidiary to, engage in
a Sale-Leaseback Transaction, unless one of the following applies:

          (1) the Sale-Leaseback Transaction occurs within one year from the date of acquisition
of the Principal Property subject thereto or the date of the completion of construction or
commencement of full operations on such Principal Property, whichever is later;

Second Supplemental Indenture

11

 

          (2) the Sale-Leaseback Transaction involves a lease for a period, including renewals,
of not more than three years;

          (3) the Company or such Restricted Subsidiary would be entitled to incur Debt secured
by a Lien on the Principal Property subject thereto in a principal amount equal to or
exceeding the net sale proceeds from such Sale-Leaseback Transaction without securing the
Notes; or

          (4) the Company or such Restricted Subsidiary, within a one-year period after such
Sale-Leaseback Transaction, applies or causes to be applied an amount not less than the net
sale proceeds from such Sale-Leaseback Transaction to (1) the repayment, redemption or
retirement of Funded Debt of the Company or any Subsidiary, or (2) investment in another
Principal Property;

     (b) Notwithstanding the immediately preceding paragraph (a), the Company or any
Restricted Subsidiary may effect any Sale-Leaseback Transaction not excepted pursuant to the
immediately preceding paragraph (a); provided that the net sale proceeds from such
Sale-Leaseback Transaction, together with the aggregate principal amount of then outstanding
Debt (other than the Notes) secured by Liens upon Principal Properties not excepted pursuant
to clauses (1) through (14) of Section 10.6(a), do not exceed 15% of Consolidated Net
Tangible Assets.

SECTION 4.3 Offer to Purchase Upon a Change of Control Triggering Event.

     Subject to the limitations set forth in the preamble to Article Four of this
Supplemental Indenture, Article Ten of the Original Indenture is hereby further amended by adding
the following Section 10.8 thereto:

     Section 10.8 Offer to Purchase Upon a Change of Control Triggering Event.

     (a) If a Change of Control Triggering Event occurs, each Holder of Notes will have the
right to require the Company to repurchase all or any part (equal to $1,000 or an integral
multiple of $1,000 in excess thereof) of that Holder’s Notes pursuant to an offer (“Change
of Control Offer”) on the terms set forth below. In the Change of Control Offer, the
Company will offer a payment in cash (the “Change of Control Payment”) equal to 101% of the
aggregate principal amount of the Notes repurchased pursuant to the foregoing, plus accrued
and unpaid interest on such Notes repurchased to the date of purchase (the “Change of
Control Payment Date”), subject to the rights of Holders of such Notes on the relevant
Record Date to receive interest due on the relevant Interest Payment Date. Within 30 days
following any Change of Control Triggering Event, the Company will mail a notice to each
Holder of Notes describing the transaction or transactions that constitute the Change of
Control Triggering Event and offering to repurchase Notes on the Change of Control Payment
Date specified in such notice, which date shall be no earlier than 30 days and no later than
60 days from the date such notice is mailed, pursuant to the procedures required by this
Indenture and described in such notice. The Company will comply with the requirements of
Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder
to the extent such laws and regulations are applicable in connection with the repurchase of
Notes as a result of a Change of Control Triggering Event. To the extent that the
provisions of any securities laws or regulations conflict with the Change of Control
Triggering Event provisions of this Indenture, the Company will comply with the applicable
securities laws and regulations and will not be deemed to have breached its obligations
under the Change of Control Triggering Event provisions of this Indenture by virtue of the
Company’s compliance with such securities laws or regulations.

Second Supplemental Indenture

12

 

     (b) With respect to any Change of Control Offer, on the Change of Control Payment Date,
the Company will, to the extent lawful:

     (i) accept for payment all Notes or portions thereof properly tendered pursuant
to the Change of Control Offer;

     (ii) deposit with the Paying Agent (to the extent the Paying Agent acts as
tender agent for such offer) an amount equal to the Change of Control Payment in
respect of all Notes or portions thereof properly tendered pursuant to the Change of
Control Offer; and

     (iii) deliver or cause to be delivered to the Trustee all Notes accepted for
purchase together with an Officer’s Certificate stating the aggregate principal
amount of the Notes or portions thereof being purchased by the Company.

     (c) Upon receipt of the Change of Control Payment from the Company, the Paying Agent
(to the extent the Paying Agent acts as tender agent for such offer) will promptly mail to
each Holder of Notes properly tendered pursuant to the Change of Control Offer the Change of
Control Payment for such Notes (or, if all the Notes are then in global form, make such
payment through the facilities of the Depositary), and the Trustee, upon receipt of a
Company Order, will promptly authenticate and mail (or cause to be transferred by book
entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the
Notes surrendered, if any; provided that each such new Note will be in a principal amount of
$2,000 or an integral multiple of $1,000 in excess thereof. Any Note so accepted for
payment will cease to accrue interest on and after the Change of Control Payment Date unless
the Company defaults in making the Change of Control Payment.

     (d) The Company will publicly announce the results of the Change of Control Offer on or
as soon as practicable after the Change of Control Payment Date.

     (e) Notwithstanding anything to the contrary in this Section 10.8, the Company will not
be required to make a Change of Control Offer with respect to the Notes upon a Change of
Control Triggering Event if (i) a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements set forth in this
Indenture that are applicable to a Change of Control Offer made by the Company and purchases
all Notes validly tendered and not withdrawn under such Change of Control Offer, or (ii)
prior to the Change of Control Triggering Event, notice of redemption of all outstanding
Notes has been given pursuant to the redemption provisions of this Indenture, unless and
until there is a default in payment of the applicable Redemption Price.

     (f) A Change of Control Offer may be made with respect to the Notes in advance of a
Change of Control Triggering Event, and conditioned upon the occurrence of such Change of
Control Triggering Event, if a definitive agreement for the Change of Control Triggering
Event is in place at the time of making the Change of Control Offer. Notes repurchased by
the Company pursuant to a Change of Control Offer will have the status of Notes issued but
not Outstanding or will be retired and cancelled, at the Company’s option. Notes purchased
by a third party pursuant to clause (e) of this Section 10.8 will have the status of Notes
issued and Outstanding.

     (g) In the event that, pursuant to this Section 10.8, the Company shall be required to
commence a Change of Control Offer, it shall follow the procedures specified above in this
Section 10.8, and, to the extent not inconsistent therewith, the procedures specified below
in this paragraph (g).

Second Supplemental Indenture

13

 

     (i) A Change of Control Offer shall remain open for a period of no less than 30
days and no more than 60 days following its commencement, except to the extent that
a longer period is required by applicable law (the “Offer Period”). Promptly after
the termination of the Offer Period, the Company shall purchase all Notes tendered
and not withdrawn in response to the Change of Control Offer in accordance with
Section 10.8(c) above.

     (ii) Upon the commencement of a Change of Control Offer, the Company shall
send, by first class mail, a notice to the Trustee and each of the Holders of Notes.
The notice shall contain all instructions and materials necessary to enable such
Holders to tender Notes pursuant to the Change of Control Offer. The Change of
Control Offer shall be made to all Holders of Notes. The notice, which shall govern
the terms of the Change of Control Offer, shall state:

     (A) that the Change of Control Offer is being made pursuant to this
Section 10.8, and the length of time the Change of Control Offer shall
remain open;

     (B) the purchase price and the Change of Control Payment Date;

     (C) that any Note not tendered and accepted for payment shall remain
outstanding for all purposes under this Indenture;

     (D) that, unless the Company defaults in making such payment, any Note
(or portion thereof) accepted for payment pursuant to the Change of Control
Offer shall cease to accrue interest after the Change of Control Payment
Date;

     (E) that Holders electing to have a Note purchased pursuant to a Change
of Control Offer may elect to have such Notes purchased equal to $1,000 and
integral multiples of $1,000 in excess thereof;

     (F) that Holders electing to have a Note purchased pursuant to any
Change of Control Offer shall be required to surrender such Note, with the
form entitled “Option of Holder to Elect Repurchase” on the reverse of the
Note completed, or transfer by book entry transfer, to the Company, the
Depositary, if appointed by the Company, or a Paying Agent (to the extent
the Paying Agent acts as tender agent for such offer) at the address
specified in the notice at least three days before the Purchase Date;

     (G) that Holders shall be entitled to withdraw their election if the
Company, the Depositary or the Paying Agent (to the extent the Paying Agent
acts as tender agent for such offer), as the case may be, receives, not
later than the expiration of the Offer Period, a telegram, telex, facsimile
transmission or letter setting forth the name of the Holder, the principal
amount of such Note the Holder delivered for purchase and a statement that
such Holder is withdrawing its election to have such Note purchased; and

     (H) that Holders whose Notes were purchased only in part, pursuant to
this section, shall be issued new Notes equal in principal amount to the
unpurchased portion of such Notes surrendered (or transferred by book entry
transfer).

     EL PASO PIPELINE PARTNERS OPERATING COMPANY, L.L.C., a Delaware limited liability company
(herein called the “Company”, which term includes any successor or resulting Person under the
Indenture hereinafter referred to), for value received, hereby promises to pay to                                         , or registered assigns, the principal sum of                                         
United States Dollars on November 15, 2015, and to pay interest thereon from November 19, 2010, or
from the most recent Interest Payment Date to which interest has been paid or duly provided for,
semi-annually on May 15 and November 15 (each, an “Interest Payment Date”) in each year, commencing
on May 15, 2011, at the rate of 4.10% per annum, until the principal hereof is paid or made
available for payment and at the same rate per annum on any overdue principal and premium and on
any overdue installment of interest (to the extent that the payment of such interest shall be

close of business on the “Regular Record Date” for such interest, which shall be the May 1 or
November 1 (whether or not a Business Day), as the case may be, next preceding such Interest
Payment Date. Any such interest not so punctually paid or duly provided for shall forthwith cease
to be payable to the Holder on such Regular Record Date and may either be paid to the Person in
whose name this Security (or one or more Predecessor Securities) is registered at the close of
business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the
Trustee, notice of which shall be given to Holders of Securities of this series not less than 10
days prior to such

and immunities thereunder of the Company, the Guarantor, the Trustee and the Holders of the
Securities and of the terms upon which the Securities are, and are to be, authenticated and
delivered. Capitalized terms used but not defined herein have the meanings set forth in the
Indenture. This Security is one of the series designated on the face hereof.

     This Security is the general, unsecured, senior obligation of the Company and is guaranteed
pursuant to a guarantee (the “Parent Guarantee”) by the Guarantor. The Parent Guarantee is the
general, unsecured, senior obligation of the Guarantor.

     This Security is redeemable, in whole or in part, at the Company’s option at any time prior to
maturity at a Redemption Price equal to the greater of (a) 100% of the principal amount of this
Security, and (b) as determined by the Quotation Agent, the sum of the present values of the
remaining scheduled payments of principal and interest (not including any portion of those payments
of interest accrued as of the date of redemption) discounted to the Redemption Date on a
semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted
Treasury Rate plus 40 basis points, plus, in each case, accrued and unpaid interest to the
Redemption Date.

     For purposes of determining any Redemption Price, the following definitions shall apply:

     “Adjusted Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal
to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price
for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the
Comparable Treasury Price for the Redemption Date. The Adjusted Treasury Rate will be calculated
on the third Business Day preceding the Redemption Date.

     “Comparable Treasury Issue” means the United States Treasury security selected by the
applicable Quotation Agent as having a maturity comparable to the remaining term of this Security
that would be utilized, at the time of selection and in accordance with customary financial
practice, in pricing new issues of corporate debt securities of comparable maturity to the
remaining term of this Security.

     “Comparable Treasury Price” means, with respect to any date of redemption, (a) the average of
four Reference Treasury Dealer Quotations for the Redemption Date, after excluding the highest and
lowest Reference Treasury Dealer Quotations, or (b) if the Company obtains fewer than four such
Reference Treasury Dealer Quotations, the average of all such Reference Treasury Dealer Quotations.

     “Quotation Agent” means the Reference Treasury Dealer appointed by the Company.

     “Reference Treasury Dealer” means (a) RBS Securities Inc., BNP Paribas Securities Corp.,
Deutsche Bank Securities Inc. and J.P. Morgan Securities LLC and their successors; provided that,
if any of the foregoing shall cease to be a primary U.S. Government securities dealer (a “Primary
Treasury Dealer”), the Company shall substitute another Primary Treasury Dealer; and (b) any other
Primary Treasury Dealers selected by the Company.

     “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer
and any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for
the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount)
quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m. (New York City
time) on the third Business Day preceding that Redemption Date.

     Unless the Company defaults in payment of the Redemption Price, on and after the Redemption
Date, interest will cease to accrue on this Security or the portions hereof called for redemption.

     In the event of redemption of this Security in part only, a new Security or Securities of this
series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder
hereof upon the cancellation hereof.

     The Company is not required to make mandatory redemption or sinking fund payments with respect
to this Security.

     If a Change of Control Triggering Event occurs, each Holder of Securities will have the right
to require the Company to repurchase all or any part (equal to $1,000 or an integral multiple of
$1,000 in excess thereof) of that Holder’s Securities pursuant to an offer (“Change of Control
Offer”) on the terms set forth in the Indenture. In the Change of Control Offer, the Company will
offer a payment in cash (the “Change of Control Payment”) equal to 101% of the aggregate principal
amount of Securities repurchased plus accrued and unpaid interest on the Securities repurchased to
the date of purchase (the “Change of Control Payment Date”), subject to the rights of Holders of
Securities on the relevant Record Date to receive interest due on the relevant Interest Payment
Date. Within 30 days following any Change of Control Triggering Event, the Company will mail a
notice to each Holder of Securities describing the transaction or transactions that constitute the
Change of Control Triggering Event and offering to repurchase Securities on the Change of Control
Payment Date specified in such notice, which date shall be no earlier than 30 days and no later
than 60 days from the date such notice is mailed, pursuant to the procedures required by the
Indenture and described in such notice.

     The Indenture contains provisions for defeasance at any time of (1) the entire indebtedness of
this Security or (2) certain restrictive covenants and Events of Default with respect to this
Security, in each case upon compliance with certain conditions set forth in the Indenture.

     If an Event of Default with respect to Securities of this series shall occur and be
continuing, the principal of the Securities of this series may be declared due and payable in the
manner and with the effect provided in the Indenture.

     The Indenture permits, with certain exceptions as therein provided, the amendment thereof and
the modification of the rights and obligations of the Company and the Guarantor and the rights of
the Holders of the Securities of each series to be affected under the Indenture at any time by the
Company and the Guarantor and the Trustee with the consent of the Holders of a majority in
principal amount of the Securities at the time Outstanding of each series to be affected (with each
series voting as a separate class). The Indenture also contains provisions permitting the Holders
of specified percentages in principal amount of the Securities of each series at the time
Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the
Company and the Guarantor with certain provisions of the Indenture and certain past defaults under
the Indenture and their consequences. Any such consent or waiver by the Holder of this Security
shall be conclusive and binding upon such Holder and upon all future Holders of this Security and
of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu
hereof, regardless of whether notation of such consent or waiver is made upon this Security.

     No Holder of this Security shall have any right to institute any proceeding, judicial or
otherwise, with respect to the Indenture, or for the appointment of a receiver or trustee, or for
any other remedy hereunder, unless (a) such Holder has previously given written notice to the
Trustee of a continuing Event of Default with respect to the Securities of this series, (b) the
Holders of not less than 25% in principal amount of the Outstanding Securities of this series shall
have made written request to the Trustee to institute proceedings in respect of such Event of
Default in its own name as Trustee hereunder, (c) such Holder or Holders have offered to the
Trustee indemnity satisfactory to the Trustee against the costs, expenses and liabilities to be
incurred in compliance with such request, (d) the Trustee for 60 days after its receipt of such
notice, request and offer of indemnity has failed to institute any such proceeding and (e) no
direction inconsistent with such written request has been given to the Trustee during such 60-day
period by the Holders of a majority in principal amount of the Outstanding Securities of this
series; it being understood and intended that no one or more of such Holders shall have any right
in any manner whatsoever by virtue of, or by availing of, any provision of this Indenture to
affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to
obtain priority or preference over any other of such Holders or to enforce any

right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all such
Holders.

     No reference herein to the Indenture and no provision of this Security or of the Indenture
shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay
the principal of and any premium and interest on this Security at the times, place(s) and rate, and
in the coin or currency, herein prescribed.

     [If a Global Security, insert—This Global Security or portion hereof may not be exchanged for
Definitive Securities of this series except in the limited circumstances provided in the Indenture.
The holders of beneficial interests in this Global Security will not be entitled to receive
physical delivery of Definitive Securities except as described in the Indenture and will not be
considered the Holders thereof for any purpose under the Indenture.]

     [If a Definitive Security, insert—As provided in the Indenture and subject to certain
limitations therein set forth, the transfer of this Security is registerable in the Security
Register, upon surrender of this Security for registration of transfer at the office or agency of
the Company in The City of New York, or, subject to any laws or regulations applicable thereto and
to the right of the Company (limited as provided in the Indenture) to rescind the designation of
any such transfer agent, at the offices of the Security Registrar in the Borough of Manhattan, The
City of New York or at such other offices or agencies as the Company may designate, duly endorsed
by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by, the Holder hereof or such Holder’s attorney duly authorized in
writing, and thereupon one or more new Securities of this series and of like tenor, of authorized
denominations and for the same aggregate principal amount, will be issued to the designated
transferee or transferees.]

     The Securities of this series are issuable only in registered form without coupons in
denominations of U.S. $2,000 and any integral multiple of U.S. $1,000 in excess thereof. As
provided in the Indenture and subject to certain limitations therein set forth, Securities of this
series are exchangeable for a like aggregate principal amount of Securities of this series and of
like tenor of a different authorized denomination, as requested by the Holder surrendering the
same.

     No service charge shall be made for any such registration of transfer or exchange, but the
Company may require payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith.

     Prior to due presentment of this Security for registration of transfer, the Company, the
Guarantor, the Trustee and any agent of the Company, the Guarantor or the Trustee may treat the
Person in whose name this Security is registered as the owner hereof for all purposes, whether or
not this Security is overdue, and none of the Company, the Guarantor, the Trustee nor any such
agent shall be affected by notice to the contrary.

     No recourse under or upon any obligation, covenant or agreement of or contained in the
Indenture or of or contained in any Security, or the Parent Guarantee endorsed thereon, or for any
claim based thereon or otherwise in respect thereof, or in any Security or in the Parent Guarantee,
or because of the creation of any indebtedness represented thereby, shall be had against any
incorporator, shareholder, partner, member, officer, manager or director, as such, past, present or
future, of the Company or the Guarantor or of any successor Person, either directly or through the
Company or the Guarantor or any successor Person, whether by virtue of any constitution, statute or
rule of law, or by the enforcement of any assessment, penalty or otherwise; it being expressly
understood that all such liability is hereby expressly waived and released by the acceptance hereof
and as a condition of, and as part of the consideration for, the execution of the Indenture and the
issuance of the Securities.

     This Security shall be governed by and construed in accordance with the laws of the State of
New York.

     All terms used in this Security which are defined in the Indenture shall have the meanings
assigned to them in the Indenture.

     EL PASO PIPELINE PARTNERS OPERATING COMPANY, L.L.C., a Delaware limited liability company
(herein called the “Company”, which term includes any successor or resulting Person under the
Indenture hereinafter referred to), for value received, hereby promises to pay to
                    , or registered assigns, the principal sum of                     
United States Dollars on November 15, 2040, and to pay interest thereon from November 19, 2010, or
from the most recent Interest Payment Date to which interest has been paid or duly provided for,
semi-annually on May 15 and November 15 (each, an “Interest Payment Date”) in each year, commencing
on May 15, 2011, at the rate of 7.50% per annum, until the principal hereof is paid or made
available for payment and at the same rate per annum on any overdue principal and premium and on
any overdue installment of interest (to the extent that the payment of such interest shall be
legally enforceable). Interest on this Security shall be computed on the basis of a 360-day year
comprised of twelve 30-day months. In the event that any date on which interest is payable on this
Security is not a Business Day, then a payment of the interest payable on such date will be made on
the next succeeding day which is a Business Day (and without any interest or other payment in
respect of any such delay) with the same force and effect as if made on the date the payment was
originally payable. A “Business Day” shall mean, when used with respect to any Place of Payment,
each Monday, Tuesday, Wednesday, Thursday and Friday which is not a day on which banking
institutions and trust companies in that Place of Payment are authorized or obligated by law,
executive order or regulation to close. The interest so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the
Person in whose name this Security (or one or more Predecessor Securities) is registered at the
close of business on the “Regular Record Date” for such interest, which shall be the May 1 or
November 1 (whether or not a Business Day), as the case may be, next preceding such Interest
Payment Date. Any such interest not so punctually paid or duly provided for shall forthwith cease
to be payable to the Holder on such Regular Record Date and may either be paid to the Person in
whose name this Security (or one or more Predecessor Securities) is registered at the close of
business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the
Trustee, notice of which shall be given to Holders of Securities of this series not less than 10
days prior to such

interest on this Security will be made by transfer of immediately available funds to a bank account

debts.]

[REVERSE OF NOTE]

EL PASO PIPELINE PARTNERS OPERATING COMPANY, L.L.C.

7.50% Senior Note due 2040

     This Security is one of a duly authorized issue of senior securities of the Company (the
“Securities”), issued and to be issued in one or more series under an Indenture, dated as of March
30, 2010, as amended and supplemented by the Second Supplemental Indenture thereto dated as of
November 19, 2010 (such Indenture, as so amended and supplemented being referred to herein as the
“Indenture”), by and among the Company, El Paso Pipeline Partners, L.P. (the “Guarantor”) and HSBC
Bank USA, National Association, a national banking association organized and existing under the
laws of the United States of America, as Trustee (the “Trustee,” which term includes any successor
trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference
is hereby made for a statement of the respective rights, limitations of rights, obligations, duties
and immunities thereunder of the Company, the Guarantor, the Trustee and the Holders of the
Securities and of the terms upon which the Securities are, and are to be, authenticated and
delivered. Capitalized terms used but not defined herein have the meanings set forth in the
Indenture. This Security is one of the series designated on the face hereof.

     This Security is the general, unsecured, senior obligation of the Company and is guaranteed
pursuant to a guarantee (the “Parent Guarantee”) by the Guarantor. The Parent Guarantee is the
general, unsecured, senior obligation of the Guarantor.

     This Security is redeemable, in whole or in part, at the Company’s option at any time prior to
maturity at a Redemption Price equal to the greater of (a) 100% of the principal amount of this
Security, and (b) as determined by the Quotation Agent, the sum of the present values of the
remaining scheduled payments of principal and interest (not including any portion of those payments
of interest accrued as of the date of redemption) discounted to the Redemption Date on a
semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted
Treasury Rate plus 50 basis points, plus, in each case, accrued and unpaid interest to the
Redemption Date.

     For purposes of determining any Redemption Price, the following definitions shall apply:

     “Adjusted Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal
to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price
for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the
Comparable Treasury Price for the Redemption Date. The Adjusted Treasury Rate will be calculated
on the third Business Day preceding the Redemption Date.

     “Comparable Treasury Issue” means the United States Treasury security selected by the
applicable Quotation Agent as having a maturity comparable to the remaining term of this Security
that would be utilized, at the time of selection and in accordance with customary financial
practice, in pricing new issues of corporate debt securities of comparable maturity to the
remaining term of this Security.

     “Comparable Treasury Price” means, with respect to any date of redemption, (a) the average of
four Reference Treasury Dealer Quotations for the Redemption Date, after excluding the highest and
lowest Reference Treasury Dealer Quotations, or (b) if the Company obtains fewer than four such
Reference Treasury Dealer Quotations, the average of all such Reference Treasury Dealer Quotations.

     “Quotation Agent” means the Reference Treasury Dealer appointed by the Company.

     “Reference Treasury Dealer” means (a) RBS Securities Inc., BNP Paribas Securities Corp.,
Deutsche Bank Securities Inc. and J.P. Morgan Securities LLC and their successors; provided that,
if any of the foregoing shall cease to be a primary U.S. Government securities dealer (a “Primary
Treasury Dealer”), the Company shall substitute another Primary Treasury Dealer; and (b) any other
Primary Treasury Dealers selected by the Company.

     “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer
and any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for
the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount)
quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m. (New York City
time) on the third Business Day preceding that Redemption Date.

Second Supplemental Indenture

     Unless the Company defaults in payment of the Redemption Price, on and after the Redemption
Date, interest will cease to accrue on this Security or the portions hereof called for redemption.

     In the event of redemption of this Security in part only, a new Security or Securities of this
series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder
hereof upon the cancellation hereof.

     The Company is not required to make mandatory redemption or sinking fund payments with respect
to this Security.

     If a Change of Control Triggering Event occurs, each Holder of Securities will have the right
to require the Company to repurchase all or any part (equal to $1,000 or an integral multiple of
$1,000 in excess thereof) of that Holder’s Securities pursuant to an offer (“Change of Control
Offer”) on the terms set forth in the Indenture. In the Change of Control Offer, the Company will
offer a payment in cash (the “Change of Control Payment”) equal to 101% of the aggregate principal
amount of Securities repurchased plus accrued and unpaid interest on the Securities repurchased to
the date of purchase (the “Change of Control Payment Date”), subject to the rights of Holders of
Securities on the relevant Record Date to receive interest due on the relevant Interest Payment
Date. Within 30 days following any Change of Control Triggering Event, the Company will mail a
notice to each Holder of Securities describing the transaction or transactions that constitute the
Change of Control Triggering Event and offering to repurchase Securities on the Change of Control
Payment Date specified in such notice, which date shall be no earlier than 30 days and no later
than 60 days from the date such notice is mailed, pursuant to the procedures required by the
Indenture and described in such notice.

     The Indenture contains provisions for defeasance at any time of (1) the entire indebtedness of
this Security or (2) certain restrictive covenants and Events of Default with respect to this
Security, in each case upon compliance with certain conditions set forth in the Indenture.

     If an Event of Default with respect to Securities of this series shall occur and be
continuing, the principal of the Securities of this series may be declared due and payable in the
manner and with the effect provided in the Indenture.

     The Indenture permits, with certain exceptions as therein provided, the amendment thereof and
the modification of the rights and obligations of the Company and the Guarantor and the rights of
the Holders of the Securities of each series to be affected under the Indenture at any time by the
Company and the Guarantor and the Trustee with the consent of the Holders of a majority in
principal amount of the Securities at the time Outstanding of each series to be affected (with each
series voting as a separate class). The Indenture also contains provisions permitting the Holders

understood that all such liability is hereby expressly waived and released by the acceptance hereof
and as a condition of, and as part of the consideration for, the execution of the Indenture and the
issuance of the Securities.

	(a)	 	Without duplication from and after the Closing Date, the Contributing Parties shall be
liable for, and shall indemnify and hold the Partnership Parties, the Elba Express Entities,
SLNG, the SNG Entities and their respective subsidiaries harmless from the Contributing
Parties’ Ownership Percentage of any Taxes, together with any costs, expenses, losses or
damages, including reasonable expenses of investigation and attorneys’ and accountants’ fees
and expenses, arising out of or incident to the determination, assessment or collection of
such Taxes (“Tax Losses”), (i) imposed on or incurred by the Elba Express Entities, SLNG or
the SNG Entities or their respective assets by reason of Treasury Regulations Section 1.1502-6
or any analogous state, local or foreign law or regulation which is attributable to the Elba
Express Entities, SLNG or the SNG Entities or the Contributing Parties having been a member of
any consolidated, combined or unitary group for the period prior to and including the Closing
Date, (ii) any Tax Losses (other than Tax Losses described in clause (i) above) imposed on or
incurred by or with respect to the Elba Express Entities, SLNG or the SNG Entities or their
assets with respect to the period prior to and including the Closing Date or (iii)
attributable to a breach by the Contributing Parties of any representation, warranty or
covenant with respect to Taxes in this Agreement, provided that the Contributing Parties shall
be liable for, and shall indemnify and hold the Partnership Parties, the Elba Express
Entities, SLNG, the SNG Entities and their respective subsidiaries harmless from the

gain, loss, deduction and credit (“Tax Items”) required to be included therein, shall cause
such Tax Return to be filed timely with the appropriate Taxing Authority, and shall be
responsible for the timely payment (and entitled to any refund) of Taxes due with respect to
the period covered by such Tax Return.

	(b)	 	With respect to any Tax Return covering a taxable period beginning on or before the Closing
Date and ending after the Closing Date that is required to be filed after the Closing Date

copy of such Tax Return to the Partnership Parties, shall cause

33

 

	 	 	such Tax Return to be filed timely with the appropriate Taxing Authority, and shall be
responsible for the timely payment of Taxes due with respect to the period covered by such
Tax Return allocable to the period prior to and including the Closing Date.

	(c)	 	Any Tax Return not yet filed for any taxable period that begins before the Closing Date with
respect to the assets or operations of the Elba Express Entities, SLNG or SNG Entities shall

the non-filing party.

this Article 7, shall be treated as increases or decreases to the Consideration for
Tax purposes.

	 	 	The Contributing Parties shall file all necessary Tax Returns and other documentation with
respect to all transfer, documentary, sales, use, stamp, registration and other similar
Taxes and fees arising out of or in connection with the transactions effected pursuant to
this Agreement (the “Transfer Taxes”) and shall be liable for and shall timely pay such
Transfer Taxes. If required by Applicable Law, the Partnership Parties shall, and shall
cause their Affiliates to, join in the execution of any such Tax Returns and other
documentation.

	 	7.5	 	Survival.

	 	 	Anything to the contrary in this Agreement notwithstanding, the representations, warranties,
covenants, agreements, rights and obligations of the Parties with respect to any Tax matter
covered by this Agreement shall survive the Closing and shall not terminate until ninety
(90) days after the expiration of the applicable statutes of limitations (including all
periods of extension and tolling) applicable to such Tax matter.

	 	7.6	 	Conflict.

	 	 	In the event of a conflict between the provisions of this Article 7 and any other
provisions of this Agreement, the provisions of this Article 7 shall control.

	 	7.7	 	Tax Characterization of Transaction.

	 	 	The Parties acknowledge and agree that the transactions contemplated by this Agreement: (i)
are properly characterized for federal income tax purposes as a sale of the Elba Express
Subject Interest, the SLNG Subject Interest, and the SNG Subject Interest by El

34

 

	 	 	Paso to the Partnership (the parent of the Operating Company which is an entity that is

to which shall be as set forth in Article 7.

	 	9.4	 	Survival.

	 	 	All the provisions of this Agreement shall survive the Closing, notwithstanding any
investigation at any time made by or on behalf of any party hereto, provided that the
representations and warranties set forth in Article 3 and Article 4 and in
any certificate delivered in connection herewith with respect to any of those
representations and warranties, and the covenants and agreements made under Section
5.1, shall terminate and expire at 12:01 a.m., Houston, Texas time, on June 1, 2012,
except (a) the representations and warranties of the Contributing Parties set forth in

terminated and expired, no indemnification shall or may be sought pursuant to Section
9.1(i)-(ii) or Section 9.2(i) by any Person who would have been entitled
pursuant to this Article 9 to indemnification on the basis of that representation
and warranty prior to its termination and expiration, provided that in the case of each
representation and warranty that shall terminate and expire as provided in this Section
9.4, no claim presented in writing for indemnification pursuant to this Article

Except as otherwise provided in this Section 9.4, the covenants and agreements
entered into pursuant to this Agreement shall survive the Closing.

37

 

	 	9.5	 	Demands.

	 	 	Each indemnified party hereunder agrees that promptly upon its discovery of facts giving
rise to a claim for indemnity under the provisions of this Agreement, including receipt by
it of notice of any demand, assertion, claim, action or proceeding, judicial or otherwise,
by any third party (such claims for indemnity involving third party claims being
collectively referred to herein as the “Indemnity Claim”), with respect to any matter as to
which it claims to be entitled to indemnity under the provisions of this Agreement, it will
give prompt notice thereof in writing to the indemnifying party, together with a detailed
statement of such information respecting any of the foregoing as it shall have and all
supporting evidence, including any Damages already incurred and its detailed estimate of any
Damages to be incurred in the future. Such notice shall include a formal demand for
indemnification under this Agreement.

	 	 	If the indemnified party knowingly failed to notify the indemnifying party thereof in
accordance with the provisions of this Agreement in sufficient time to permit the
indemnifying party or its counsel to defend against an Indemnity Claim and to make a timely
response thereto, the indemnifying party’s indemnity obligation relating to such Indemnity
Claim shall be limited to the extent that such failure has actually prejudiced or damaged
the indemnifying party with respect to that Indemnity Claim.

	 	9.6	 	Right to Contest and Defend.

	 	 	The indemnifying party shall be entitled, at its cost and expense, to contest and defend by
all appropriate legal proceedings any Indemnity Claim for which it is called upon to
indemnify the indemnified party under the provisions of this Agreement; provided, that
notice of the intention to so contest shall be delivered by the indemnifying party to the
indemnified party within twenty (20) days from the date of receipt by the indemnifying party
of notice by the indemnified party of the assertion of the Indemnity Claim. Any such
contest may be conducted in the name and on behalf of the indemnifying party or the
indemnified party as may be appropriate. Such contest shall be conducted by reputable
counsel employed by the indemnifying party and not reasonably objected to by the indemnified
party, but the indemnified party shall have the right but not the obligation to participate
in such proceedings and to be represented by counsel of its own choosing at its sole cost
and expense.

	 	 	The indemnifying party shall have full authority to determine all action to be taken with
respect thereto; provided, however, that the indemnifying party will not have the authority
to subject the indemnified party to any obligation whatsoever, other than the performance of
purely ministerial tasks or obligations not involving material expense or injunctive relief.
If the indemnifying party does not elect to contest any such Indemnity Claim, the
indemnifying party shall be bound by the result obtained with respect thereto by the
indemnified party. If the indemnifying party assumes the defense of an Indemnity Claim, the
indemnified party shall agree to any settlement, compromise or discharge of an Indemnity
Claim that the indemnifying party may recommend and that by its terms obligates the
indemnifying party to pay the full amount of the liability in connection with such Indemnity
Claim, which releases the indemnified party completely in connection

38

 

	 	 	with such Indemnity Claim and which would not otherwise adversely affect the indemnified
party as reasonably determined by the indemnified party.

	 	 	Notwithstanding the foregoing, the indemnifying party shall not be entitled to assume the
defense of any Indemnity Claim (and shall be liable for the reasonable fees and expenses of
counsel incurred by the indemnified party in defending such Indemnity Claim) if the
Indemnity Claim seeks an order, injunction or other equitable relief or relief for other
than money damages against the indemnified party which the indemnified party reasonably
determines, after conferring with its outside counsel, cannot be separated from any related
claim for money damages. If such equitable relief or other relief portion of the Indemnity
Claim can be so separated from that for money damages, the indemnifying party shall be
entitled to assume the defense of the portion relating to money damages.

	 	9.7	 	Cooperation.

	 	 	If requested by the indemnifying party, the indemnified party agrees to cooperate with the
indemnifying party and its counsel in contesting any Indemnity Claim that the indemnifying
party elects to contest or, if appropriate, in making any counterclaim against the person
asserting the Indemnity Claim, or any cross-complaint against any person, and the
indemnifying party will reimburse the indemnified party for any expenses incurred by it in
so cooperating. At no cost or expense to the indemnified party, the indemnifying party
shall cooperate with the indemnified party and its counsel in contesting any Indemnity
Claim.

	 	9.8	 	Right to Participate.

	 	 	The indemnified party agrees to afford the indemnifying party and its counsel the
opportunity to be present at, and to participate in, conferences with all Persons, including
Governmental Authorities, asserting any Indemnity Claim against the indemnified party or
conferences with representatives of or counsel for such Persons.

	 	9.9	 	Payment of Damages.

	 	 	The indemnification required hereunder shall be made by periodic payments of the amount
thereof during the course of the investigation or defense, within ten (10) days as and when
reasonably specific bills are received or loss, liability, claim, damage or expense is
incurred and reasonable evidence thereof is delivered. In calculating any amount to be paid
by an indemnifying party by reason of the provisions of this Agreement, the amount shall be
reduced by (a) all insurance proceeds and any indemnification reimbursement proceeds
received from third parties credited to or received by the other party related to the
Damages and (b) any Tax benefit to be realized by the indemnified party related to the
Damages.

	 	9.10	 	Limitations on Indemnification.

	(a)	 	To the extent that the Partnership Indemnified Parties are entitled to indemnification for
Damages pursuant to Section 9.1(i) and Section 9.1(ii), the Contributing
Parties shall be liable only for those Damages that in the aggregate are in excess of 1.0% of
the

39

 

	 	 	Consideration (the “Deductible Amount”), and then only to the extent of any such excess. In
no event shall the Contributing Parties’ aggregate liability to the Partnership Indemnified
Parties under Section 9.1(i) exceed 15% of the Consideration (the “Ceiling Amount”).
Notwithstanding the foregoing, (i) the Deductible Amount shall not apply to inaccuracies,
violations or breaches of representations and warranties contained in Section 3.1,
Section 3.2, Section 3.4, Section 3.14 and Section 3.16 and
(ii) the Ceiling Amount shall not apply to inaccuracies, violations or breaches of
representations and warranties contained in Section 3.2, Section 3.3,
Section 3.4, and Section 3.16 provided, the Contributing Parties’ aggregate
liability for a breach of Section 3.2, Section 3.3, Section 3.4 and
Section 3.16 shall not exceed the amount of the Consideration.

	(b)	 	To the extent the Contributing Indemnified Parties are entitled to indemnification for
Damages pursuant to Section 9.2(i), the Partnership Parties shall be liable only for
those Damages which exceed, in the aggregate, the Deductible Amount, and then only to the
extent of any such excess. In no event shall the Partnership Parties’ aggregate liability to
the Contributing Indemnified Parties under Section 9.2(i) exceed the Ceiling Amount.
Notwithstanding the foregoing, (i) the Deductible Amount shall not apply to inaccuracies,
violations or breaches of representations and warranties contained in Section 4.1,
Section 4.2 and Section 4.4 and (ii) the Ceiling Amount shall not apply to
inaccuracies, violations or breaches of representations and warranties contained in
Section 4.2, Section 4.3 and Section 4.4 provided, the Partnership
Parties’ aggregate liability for a breach of Section 4.2, Section 4.3 and
Section 4.4 shall not exceed the amount of the Consideration.

	(c)	 	Additionally, neither the Partnership Parties, on the one hand, nor the Contributing Parties,
on the other hand, will be liable as an indemnitor under this Agreement for any consequential,
incidental, special, indirect or exemplary damages suffered or incurred by the indemnified
party or parties.

	(d)	 	The Parties agree that any indemnification or payment obligation of the Contributing Parties
under Section 9.1(i) (to the extent relating to an inaccuracy, violation or breach of
a representation or warranty in Section 3.1(b)-(c), Section 3.4(b) (as
applicable), or Sections 3.5 through 3.15, or Sections 3.18 through
3.20) relating to Damages suffered or incurred by the Partnership Indemnified Parties,
attributable to any SNG Entity, Elba Express Entity or SLNG or their assets, businesses or
operations shall be limited to a proportionate share of the total (100%) Damages attributable
to any such inaccuracy, violation or breach, which proportionate share shall be equal to 15%,
49% and 49%, respectively. The Parties agree that El Paso is solely liable with respect to
any indemnification or payment obligation pursuant to this Article 9 relating to Damages
suffered or incurred by the Partnership Indemnified Parties associated with any of the SNG
Entities’ assets, businesses or operations. The Parties agree that the Contributing Parties
are jointly and severally liable for any indemnification or payment obligation pursuant to
this Article 9 of the Contributing Parties relating to any remaining Damages suffered or
incurred by the Partnership Indemnified Parties that are not directly attributable to any SNG
Entity or their respective assets, businesses or operations.

	 	9.11	 	Sole Remedy.

	 	 	Should the Closing occur, no party shall have liability under this Agreement, any of the

	 	10.5	 	Entire Agreement; Amendments and Waivers.

	(a)	 	This Agreement and the Ancillary Documents constitute the entire agreement among the Parties
with respect to the subject matter hereof and supersede all prior agreements and
understandings, both written and oral, among the Parties with respect to the subject matter
hereof. Each party to this Agreement agrees that no other party to this Agreement (including
its agents and representatives) has made any representation, warranty, covenant or agreement
to or with such party relating to this Agreement or the transactions contemplated hereby,
other than those expressly set forth herein and in the Ancillary Documents.

	(b)	 	No supplement, modification or waiver of this Agreement shall be binding unless executed in
writing by each party to be bound thereby. No waiver of any of the provisions of this
Agreement shall be deemed or shall constitute a waiver of any other provision hereof
(regardless of whether similar), nor shall any such waiver constitute a continuing waiver

	 	10.6	 	Conflicting Provisions.

	 	 	This Agreement and the other Ancillary Documents, read as a whole, set forth the Parties’
rights, responsibilities and liabilities with respect to the transactions contemplated by
this Agreement. In the Agreement and the Ancillary Documents, and as between them, specific
provisions prevail over general provisions. In the event of a

42

 

	 	 	conflict between this Agreement and the Ancillary Documents, this Agreement shall control.

	 	10.7	 	Binding Effect and Assignment.

	 	 	This Agreement shall be binding upon and inure to the benefit of the Parties and their
respective permitted successors and assigns, but neither this Agreement nor any of the
rights, benefits or obligations hereunder shall be assigned or transferred, by operation of
law or otherwise, by any party hereto without the prior written consent of each other party.
Notwithstanding anything in this Section 10.7, any Party may (without seeking the
consent of the other Parties) transfer or otherwise alienate any of its rights, title,
interest or obligations under this Agreement in connection with (i) a transfer to an
Affiliate which remains an Affiliate, (ii) the granting of a pledge, mortgage,
hypothecation, lien or other security interest, (iii) the foreclosure (judicial or
non-judicial) or other settlement or rearrangement pursuant to or in connection with any
transfer made pursuant to (ii) above, (iv) a transfer in connection with the sale of all or
substantially all of the assets of such Party, if applicable, or (v) a merger,
consolidation, share exchange or other form of statutory reorganization with another Person
if such Party is the sole surviving Person. Nothing in this Agreement, express or implied,
is intended to confer upon any person or entity other than the Parties and their respective
permitted successors and assigns, any rights, benefits or obligations hereunder.

	 	10.8	 	Severability.

	 	 	If any provision of the Agreement is rendered or declared illegal or unenforceable by reason
of any existing or subsequently enacted legislation or by decree of a court of last resort,
the Partnership Parties and the Contributing Parties shall promptly meet and negotiate
substitute provisions for those rendered or declared illegal or unenforceable, but all of
the remaining provisions of this Agreement shall remain in full force and effect.

	 	10.9	 	Interpretation.

	 	 	It is expressly agreed by the Parties that neither this Agreement nor any of the Ancillary
Documents shall be construed against any party, and no consideration shall be given or
presumption made, on the basis of who drafted this Agreement, any Ancillary Document or any
provision hereof or thereof or who supplied the form of this Agreement or any of the
Ancillary Documents. Each party agrees that this Agreement has been purposefully drawn and
correctly reflects its understanding of the transactions contemplated by this Agreement and,
therefore, waives the application of any law, regulation, holding or rule of construction
providing that ambiguities in an agreement or other document will be construed against the
party drafting such agreement or document.

	 	10.10	 	Headings and Disclosure Schedules.

	 	 	The headings of the several Articles and Sections herein are inserted for convenience of
reference only and are not intended to be a part of or to affect the meaning or
interpretation of this Agreement. The Disclosure Schedules and the Exhibits referred to
herein are attached hereto and incorporated herein by this reference, and unless the

43

 

	 	 	context expressly requires otherwise, the Disclosure Schedules and such Exhibits are
incorporated in the definition of “Agreement.”

	 	10.11	 	Multiple Counterparts.

	 	 	This Agreement may be executed in one or more counterparts, each of which shall be deemed an
original, but all of which together shall constitute one and the same instrument.

	 	10.12	 	Action by Partnership Parties.

	 	 	With respect to any action, notice, consent, approval or waiver that is required to be taken
or given or that may be taken or given by the Partnership Parties prior to the Closing Date,
such action, notice, consent, approval or waiver shall be taken or given by the Conflicts
Committee on behalf of the Partnership Parties.

	 	10.13	 	Limitation on Recourse.

	 	 	Except as otherwise expressly provided to contrary in the last clause of this sentence, each
of the Parties agree that the payment and performance of any obligations of a party hereto
shall be the obligations of party only and none of the other Parties shall have any claim
against or recourse to (whether by operation of law or otherwise) any shareholder, member or
partner of such Party in respect of the obligations of such Party; provided that nothing in
this Section shall limit or impair the rights of the Parties to enforce their any rights
against such shareholder, member or partner set forth in this Agreement.

Schedule 3.8

Litigation; Laws and Regulations

A. Litigation

The following lawsuits are pending or have been threatened:

MMS Royalty Claim. Potential reimbursement obligation owed to Total E&P USA associated
with five take-or-pay contract settlements reached in the late 1980s with Total’s predecessor.

Louisiana Crawfish Producers Association West v. Amerada Hess, et al. Louisiana State
District Court.

Lloyds Litigation. Alabama state court action. SNG is the plaintiff in this case.

Other Litigation. Southern LNG Company, L.L.C. (“SLNG”), Elba Express Company, L.L.C.
(“EEC”) and Southern Natural Gas Company (“SNG”) are involved in other litigation that arise in the
ordinary course of business, including without limitation less material commercial disputes,
various condemnation lawsuits associated with expansion projects, property tax cases, escheat
matters, landowner disputes and collection matters.

B. Ad Valorem Tax Disputes

SLNG currently has ad valorem tax disputes relating to three issues: 1) personal property valuation
for the period 2003-2007; 2) tax on the gas in inventory; and 3) centralized assessment of SLNG by
the Georgia Department of Revenue. SLNG paid over $9M in taxes on personal property to Chatham
County for 2003-2007 based on original and agreed valuation. Recent retroactive audits, which are
allowed by statute, increased the property values and SLNG has recently been assessed an additional
$3.5M. Chatham County has never sent tax bills based on the higher values; therefore, the $3.5
million is not currently due and has not been paid. In addition SLNG has disputed approximately $1
million of ad valorem taxes in 2008, arguing that valuation should be established through a unit
value rather than a cost approach.

SLNG has filed protests challenging the new assessment and has entered into arbitration. These
protests are pending determination in an optional arbitration program under the jurisdiction of the
superior court, with a referee administering the arbitration. At the arbitration held on 1/25 and
1/26/10, the issue for decision for each year was the fair market value of the taxable personal
property owned by the taxpayer in Chatham County. The fundamental difference in the party’s
positions was the approach to the valuation of the personal property for ad valorem tax purposes.
Southern LNG’s position was that the correct way to value FERC regulated property is by the unit
value approach. On the other hand, it appears the County has valued the personal property using a
basic cost approach with no economic obsolescence. At the hearing, the Board of Tax Assessors had
the burden of proving their opinions of value by a preponderance of the evidence. On March 18,
2010, the panel rendered its unanimous awards in each of the five tax

 

 

years. It is
estimated that these awards will result in additional tax of $146,300 total for all five years.
The county had sought increased values that would have resulted in additional tax of $3,163,175.
This ruling has been appealed to the district court for a trial de novo.

C. FERC Regulatory Proceedings — The following proceedings are pending before the Federal
Energy Regulatory Commission (“FERC”) or on appeal from the FERC:

SLNG, EEC, and Southern Natural Gas Company, 120 FERC ¶61,258 (2007), Order Issuing
Certificates, Authorizing Abandonments, Granting Authorization and Denying Rehearing, requiring
compliance with certain environmental conditions listed in Appendix B thereto.

SLNG, Docket No. CP10-477. (Truck Loading Facilities). Application to abandon certain
facilities and to reactivate, expand, operate and lease truck loading facilities.

SLNG, Docket No. RP10-829. (Gas Quality). Tariff filing to implement new gas quality and
interchangeability standards.

MOPS Abandonment (CP10-82). Proposal to abandon non-contiguous facilities that are
jointly owned by Northern Natural, SNG and FGT. Application has been protested by producers in
the area that oppose the abandonment.

EC23 Abandonment (CP11-14). Proposal to abandon facilities that are jointly owned by
SNG and Columbia Transmission Company, and transportation service through such facilities.

SLNG, EEC and SNG are regulated by the FERC and are involved in other regulatory proceedings that
arise in the ordinary course of business, including without limitation less material tariff
filings, smaller expansion projects, reporting and accounting requirements, and audits. The
recourse rates and negotiate rates that SLNG and EEC may charge are subject to the jurisdiction of
the FERC. In addition, the rates that SNG charges are subject to the jurisdiction of the FERC.
Under its current settlement agreement in Docket No. RP09-427, SNG is permitted to file a rate case
to be effective no earlier than September 1, 2012 and is required to file a rate case to be
effective no later than September 1, 2013.

D. PHMSA Proceedings

PHMSA Audit and NOPV. Pipeline and Hazardous Materials Safety Administration (“PHMSA”)
issued a Notice of Probable Violation, Proposed Civil Penalty and Proposed Compliance Order
(“Notice”) to El Paso Pipeline Group.

PHMSA CAOs — PHMSA has issued Corrective Action Orders (CAOs) directing SNG to take
certain corrective actions with respect to failures on: 1) 24-inch North Main Loop line near
Heflin, AL, 2) 24-inch North Main Line near the Louisville, MS Compressor Station, and 3) 20-inch
line near Toca, LA.

Schedule 3.11

Environmental Matters

A. Remediation Projects — SNG

General Background. SNG is subject to federal, state and local laws and regulations
governing environmental quality and pollution control. These laws and regulations require us to
remove or remedy the effect on the environment of the disposal or release of specified substances
at current and former operating sites. At September 30, 2010, SNG had accrued less than $1 million
for expected remediation costs and associated onsite, offsite and groundwater technical studies.

CERCLA Restitution Notice (EPA). SNG was named as potentially responsible party (PRP)
under a previous settlement entered into with the EPA in 1999 relating to the Port Refinery
Superfund Site in Rye Brook, New York. EPA has stated that it is seeking a total of $7 million in
reimbursement from a number of parties. Based on the small amount of material sent by SNG to this
site and the precedence of the prior settlement, SNG believes that EPA will only be seeking a de
minimis settlement from SNG.

Sandy Hook Site. Remediation activities are ongoing along pipeline site formerly owned by
SNG.

Iron Bowl Site. Conducting groundwater monitoring in response to historical hydrocarbon
release. 

B. Compliance Matters — SNG

Notice of Violation, Albany, Georgia Compressor Station. On October 22, 2010, the Georgia
Environmental Protection Division (GEPD) issued a notice of violation (NoV) to SNG concerning
turbine no. 3 at SNG’s Albany, Georgia compressor station. The NoV concerns the control set point
for the combustor outlet temperature for that turbine and whether such set point was set correctly
based on previously-conducted testing and related reporting issues. GEPD has provided a deadline
of late November for SNG to respond. The NoV does not state what amount of, if any, penalty may be
sought.

We expect to make capital expenditures for environmental matters of approximately $2 million in the
aggregate for the remainder of 2010 through 2014, primarily, to be expended from 2010 to 2013
associated with the impact of the EPA rule related to emissions of hazardous air pollutants from
reciprocating internal combustion engines which was finalized in August 2010. Our engines that are
subject to the regulations have to be in compliance by October 2013.

C. Compliance Matters — SLNG

Notice of Violation, Train III Vaporizers. Pursuant to the terms of our air permits for the
SLNG’s Train III vaporizers, we are required to submit reports to the GEPD with regard to
compliance

 

 

with such permits. We have conducted an initial performance test and a Relative Accuracy Test
Audit (RATA) on the Predictive Emissions Monitoring System (PEMS) for the Train III vaporizers and
submitted reports to GEPD concerning those actions and we are currently in discussions with GEPD
concerning these tests and reports. On November 2, 2010, GEPD issued a NoV to SLNG alleging
violations of SLNG’s air permit related to these issues. The NoV does not specify if any penalty
will be sought. SLNG’s response to the NoV is due by December 8, 2010.

 

 

Schedule 3.12

Licenses; Permits

1. SLNG, EEC, and Southern Natural Gas Company, 120 FERC ¶61,258 (2007), Order Issuing
Certificates, Authorizing Abandonments, Granting Authorization and Denying Rehearing, requiring
compliance with certain environmental conditions listed in Appendix B thereto.

2. The following projects are in various stages of permitting:

SNG

Southeast Supply Header (SESH) (CP09-40, et al.) — Joint certificate application of SESH
and SNG pipeline expansion — Phase II — project. The Phase II Expansion Project involves the
addition of new compressor engines at two existing compressor stations which will increase the
total capacity of the jointly-owned SESH pipeline from 1,140,000 MMBtu/d to 1,500,000 MMBtu/d. The
expansion will increase SNG’s share of the capacity to 500,000 MMcf/d.

South System III Expansion (CP09-36) — Expansion of SNG pipeline system to serve Southern
Company’s plant McDonough that is being constructed in Atlanta, Georgia. The project is to be built
in three phases for a total Southern Company contract quantity equal to 375 MMcf/d. The first phase
of the project will be placed into service in approximately January, 2011. FERC approval was
received on August 27, 2009.

Pipeline Integrity (Coupled Pipe) (CP10-36) — Replacement and/or abandonment of certain
segments of SNG’s North Main and North Main Loop lines west of its Louisville, Mississippi
Compressor Station. FERC approval was received on April 7, 2010.

Form of Certificate of Non-Foreign Status

Section 1445 of the Internal Revenue Code provides that a transferee (buyer) of a U.S. real
property interest must withhold tax if the transferor (seller) is a foreign person. To inform the
transferee that withholding of tax is not required upon the disposition of a U.S. real property
interest by El Paso Corporation (“El Paso”), the undersigned hereby certifies as follows:

	 	1.	 	El Paso is not a nonresident alien, foreign corporation, foreign
partnership, foreign trust, or foreign estate for purposes of U.S. income taxation
(as those terms are defined in the Internal Revenue Code of 1986, as amended and
the Treasury regulations thereunder);
	 
	 	2.	 	El Paso is not a disregarded entity as defined in §
1.1445-2(b)(2)(iii);
	 
	 	3.	 	El Paso’s taxpayer identifying number is 76-0568816; and
	 
	 	4.	 	El Paso’s office address is 1001 Louisiana Street, Houston, Texas
77002.

El Paso understands that this certification may be disclosed to the Internal Revenue Service by the
buyer and that any false statement contained herein could be punished by fine, imprisonment, or
both.

Under penalty of perjury, I declare that I have examined this certification and, to the best of my
knowledge and belief, it is true, correct, and complete, and I further declare I have authority to
sign this document.

EL PASO PIPELINE PARTNERS, L.P.

1001 Louisiana Street

Houston, Texas 77002

(713) 420-2600

$[718],000,000 Floating Rate Senior Notes, due [                    ], 2011

Dated as of [                    ], 2010

TO EACH OF THE PURCHASERS LISTED IN

          THE ATTACHED SCHEDULE A:

Ladies and Gentlemen:

          EL PASO PIPELINE PARTNERS OPERATING COMPANY, L.L.C., a Delaware limited liability company (the
“Issuer”), and EL PASO PIPELINE PARTNERS, L.P., a Delaware limited partnership (the “MLP”), agree
with each of the purchasers whose names appear at the end hereof (each, a “Purchaser” and
collectively, the “Purchasers”) as follows:

1. AUTHORIZATION OF NOTES.

1.1 Description of Notes to be Initially Issued.

          The Issuer has authorized the issue and sale of $[718],000,000 aggregate principal amount of
its Floating Rate Senior Notes, due 360 days from the date of issuance, 2011 (the “Notes”, such
term to include any such notes issued in substitution therefor pursuant to Section 13 of
this Agreement). The Notes shall be substantially in the form set out in Exhibit 1.1, with
such changes therefrom, if any, as may be approved by the Purchasers and the Issuer. Certain
capitalized terms used in this Agreement are defined in Schedule B; references to a
“Schedule” or an “Exhibit” are, unless otherwise specified, to a Schedule or an Exhibit attached to
this Agreement.

1.2 Interest Rate.

          (a) The Notes shall bear interest (computed on the basis of a 360-day year and actual days
elapsed) (i) on the unpaid principal thereof from the date of issuance at the rate stated in clause
(a) of the first paragraph of the Note payable quarterly in arrears on the last day of March, June,
September and December in each year commencing on [                    ], 20[__], until such principal sum
shall have become due and payable (whether at maturity, upon prepayment or otherwise) and (ii) to
the extent permitted by applicable law, on any overdue principal, any

 

 

overdue installment of interest and any overdue payment of LIBOR Breakage Amount from the due
date thereof (whether by acceleration or otherwise) at the applicable Default Rate until paid.

          (b) Whenever the Applicable Floating Rate consists of the Adjusted LIBOR Rate, the Adjusted
LIBOR Rate shall be determined by the Issuer, and notice thereof shall be given to the holders of
the Notes, together with such information as the holders of the Notes may reasonably request for
verification (including in all events, a facsimile transmission of the relevant screen and
calculations), on the second Business Day preceding each Interest Period. In the event that the
Required Holders do not concur with such determination by the Issuer, as evidenced by notice to the
Issuer by such Required Holders within ten (10) Business Days after receipt by such holders of the
notice delivered by the Issuer pursuant to the previous sentence, the determination of the Adjusted
LIBOR Rate shall be made by the Required Holders in accordance with the provisions of this
Agreement and shall be conclusive and binding absent manifest error.

1.3 Guaranties; Release.

     (a) Subsidiary Guaranty. The payment by the Issuer of all amounts due on or in
respect of the Notes and the performance by the Issuer of its obligations under this
Agreement will be guaranteed by each Subsidiary Guarantor executing and delivering a
subsidiary guaranty in substantially the form of the attached Exhibit 1.3(a), as it
may be amended or supplemented from time to time (a “Subsidiary Guaranty”), after the date
of this Agreement in accordance with Section 9.7.

     (b) Parent Guaranty. The payment by the Issuer of all amounts due on or in
respect of the Notes and the performance by the Issuer of its obligations under this
Agreement will be guaranteed by the MLP pursuant to a parent guaranty in substantially the
form of the attached Exhibit 1.3(b), as it may be amended or supplemented from time
to time (the “Parent Guaranty”).

     (c) Release of Guaranties. Each holder of a Note acknowledges and agrees that
a Subsidiary Guarantor shall be fully released and discharged from its Subsidiary Guaranty
and each holder of a Note fully releases and discharges such Subsidiary Guarantor from its
Subsidiary Guaranty immediately and without any further act, upon such Subsidiary being
released and discharged as a guarantor under and in respect of the Credit Agreement;
provided that (i) no Default or Event of Default exists or will exist immediately following
such release and discharge; (ii) if any fee or other consideration is paid or given to any
holder of Indebtedness under the Credit Agreement in connection with such release, other
than the repayment of all or a portion of such Indebtedness under the Credit Agreement, each
holder of a Note receives equivalent consideration on a pro rata basis; and (iii) at the
time of such release and discharge, the Issuer delivers to each holder of a Note a
certificate of a Responsible Officer certifying (a) that such Subsidiary Guarantor has been
or is being released and discharged as a guarantor under and in respect of the Credit
Agreement and (b) as to the matters set forth in clauses (i) and (ii).

2. SALE AND PURCHASE OF NOTES.

          Subject to the terms and conditions of this Agreement, the Issuer will issue and sell to each
Purchaser and each Purchaser will purchase from the Issuer, at the Closing provided for in
Section 3, Notes in the denomination, principal amount and series specified opposite such
Purchaser’s name in Schedule A at the purchase price of [100]% of the principal amount
thereof. The Purchasers’ obligations hereunder are several and not joint obligations and no
Purchaser shall have any liability to any Person for the performance or non-performance of any
obligation hereunder by any other Purchaser.

3. CLOSING.

          The sale and purchase of the Notes to be purchased by each Purchaser shall occur at the
offices of El Paso Corporation at 1001 Louisiana Street, Houston, Texas 77002 at [9:00 a.m.],
Houston time, at a closing (the “Closing”) on [                    , 2010] or on such other Business Day
thereafter on or prior to [                    , 2010] as may be agreed upon by the Issuer and the Purchasers.
At the Closing the Issuer will deliver to each Purchaser the Notes to be purchased by it in the
form of a single Note (or such greater number of Notes in denominations of at least $100,000 as
such Purchaser may request) dated the date of this Agreement and registered in such Purchaser’s
name (or in the name of such Purchaser’s nominee), against delivery by such Purchaser to the Issuer
or its order of immediately available funds in the amount of the purchase price therefor by wire
transfer of immediately available funds for the account of the Issuer to account number [100-8944
at Mellon Bank, Pittsburgh, Pennsylvania, ABA No. 043 000 261], FAO: El Paso Pipeline Partners
Operating Company, L.L.C. If at the Closing the Issuer fails to tender such Notes to each
Purchaser as provided above in this Section 3, or any of the conditions specified in
Section 4 shall not have been fulfilled to such Purchaser’s satisfaction, such Purchaser
shall, at its election, be relieved of all further obligations under this Agreement, without
thereby waiving any rights it may have by reason of such failure or such nonfulfillment.

4. CONDITIONS TO CLOSING.

          Each Purchaser’s obligation to purchase and pay for the Notes to be sold to it at the Closing
is subject to the fulfillment to such Purchaser’s satisfaction, prior to or at the Closing, of the
following conditions:

laws of its jurisdiction of organization, and is duly qualified and is in good standing in each
jurisdiction in which such qualification is required by law, other than those jurisdictions as to

company or limited partnership action (as the case may be) on the part of the Issuer, and this
Agreement constitutes, and upon execution and delivery thereof each Note will constitute, a legal,
valid and binding obligation of the Issuer enforceable against the Issuer in accordance with its
terms, except as such enforceability may be limited by (i) applicable bankruptcy, insolvency,
reorganization, moratorium or other similar laws affecting the enforcement of creditors’ rights
generally and (ii) general principles of equity (regardless of whether such enforceability is
considered in a proceeding in equity or at law).

          (b) The Parent Guaranty and this Agreement have been duly authorized by all necessary limited

5.3, this Agreement, the Information Document, the documents, certificates or other writings
delivered to the Purchasers by or on behalf of the Issuer in connection with the transactions
contemplated hereby and the financial statements listed in Schedule 5.5, taken as a whole,
do not contain any untrue statement of a material fact or omit to state any material fact necessary
to make the statements therein not misleading in light of the circumstances under which they were

that such information was prepared in good faith based upon assumptions believed to be reasonable
at the time. Except as disclosed in the Information Document or as expressly described in
Schedule 5.3, or in one of the documents, certificates or other writings identified
therein, or in the financial statements listed in Schedule 5.5, since [September 30], 2010,
there has been no change in the financial condition, operations, business or properties of the MLP,

condition known to the Issuer or the MLP that could reasonably be expected to have a Material
Adverse Effect has occurred or exists and has not been set forth herein or in the Information

other power and authority to own or hold under lease the properties it purports to own or
hold under lease and to transact the business it transacts and proposes to transact.

     (d) Except as permitted under Section 10.9, no Subsidiary of the MLP or the
Issuer is party to, or otherwise subject to, any legal restriction or any agreement (other
than this Agreement, the Credit Agreement, the agreements listed on Schedule 10.9
and customary limitations imposed by corporate, partnership or limited liability company law

other than any such liabilities arising in the ordinary course of business subsequent to the date
of such financial statements.

5.6 Compliance with Laws, Other Instruments, etc.

          (a) The execution, delivery and performance by the Issuer of this Agreement and the Notes will
not (i) contravene, result in any breach of, or constitute a default under, or result in the
creation of any Lien in respect of any property of the Issuer or any of its Subsidiaries under, any
indenture, mortgage, deed of trust, loan, note purchase or credit agreement, lease, Organization
Document, or any other Material agreement or instrument to which the Issuer or any such Subsidiary
is bound or by which the Issuer or any such Subsidiary or any of their respective properties may be
bound or affected, (ii) conflict with or result in a breach of any of the terms, conditions or
provisions of any order, judgment, decree, or ruling of any court, arbitrator or Governmental

bound or affected, (ii) conflict with or result in a breach of any of the terms, conditions or

          No consent, approval or authorization of, or registration, filing or declaration with, any
Governmental Authority is required in connection with the execution, delivery or performance by (a)
the Issuer of this Agreement or the Notes, or (b) the MLP of the Parent Guaranty or this Agreement.

5.8 Litigation; Observance of Agreements, Statutes and Orders.

     (a) There are no actions, suits or proceedings pending or, to the knowledge of the MLP
or the Issuer, threatened against or affecting the MLP, the Issuer or any Subsidiary thereof
or any property of the MLP, the Issuer or any Subsidiary thereof in any court or before any
arbitrator of any kind or before or by any Governmental Authority that, individually or in
the aggregate, could reasonably be expected to have a Material Adverse Effect.

     (b) None of the MLP, the Issuer or any Subsidiary thereof is in default under any term
of any agreement or instrument to which it is a party or by which it is bound, or any order,
judgment, decree or ruling of any court, arbitrator or Governmental Authority or is in

and the USA Patriot Act) of any Governmental Authority, which

8

 

default or violation, individually or in the aggregate, could reasonably be expected to
have a Material Adverse Effect.

5.9 Taxes.

          The MLP, the Issuer and its Subsidiaries have filed all tax returns that are required to have
been filed in any jurisdiction, and have paid all taxes shown to be due and payable on such returns
and all other taxes and assessments levied upon them or their properties, assets, income or
franchises, to the extent such taxes and assessments have become due and payable and before they
have become delinquent, except for any taxes and assessments (i) the failure to file or pay which,
as applicable, would have a Material Adverse Effect or (ii) the amount, applicability or validity
of which is currently being diligently contested in good faith by appropriate proceedings and with
respect to which the MLP, the Issuer or such Subsidiary, as the case may be, has established
adequate reserves in accordance with GAAP. The Issuer knows of no basis for any other tax or
assessment that could reasonably be expected to have a Material Adverse Effect. The charges,
accruals and reserves on the books of the MLP, the Issuer and its Subsidiaries in respect of
Federal, state or other taxes for all fiscal periods are adequate.

5.10 Title to Property; Leases.

          The MLP, the Issuer and its Subsidiaries have good and sufficient title to their respective
properties except for such defects of title as could not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect, in each case free and clear of Liens
prohibited by this Agreement. All leases of the MLP, the Issuer or any Subsidiary are valid and
subsisting and are in full force and effect in all material respects, except leases the failure of
which to maintain, individually or in the aggregate, could not reasonably be expected to have a
Material Adverse Effect.

     (a) The MLP, the Issuer and its Subsidiaries own or possess all licenses, permits,
franchises, authorizations, patents, copyrights, proprietary software, service marks,
trademarks and trade names, or rights thereto, except to the extent that the failure to own
or possess the same could not reasonably be expected to have a Material Adverse Effect, and
there are no known conflicts of the same with the rights of others that could reasonably be
expected to have a Material Adverse Effect.

     (b) To the best knowledge of the MLP and the Issuer, no product of the MLP, the Issuer
or any Subsidiary of the Issuer infringes any license, permit, franchise, authorization,
patent, copyright, proprietary software, service mark, trademark, trade name or other right
owned by any other Person, which infringement could reasonably be expected to have a
Material Adverse Effect.

     (c) To the best knowledge of the MLP and the Issuer, there is no violation by any
Person of any right of the MLP, the Issuer or any Subsidiary of the Issuer with respect to
any patent, copyright, proprietary software, service mark, trademark, trade name or other
right owned or used by the MLP, the Issuer or any Subsidiary of the Issuer, the violation of
which could reasonably be expected to have a Material Adverse Effect.

9

 

5.12 Compliance with ERISA.

     (a) No Termination Event has occurred or is reasonably expected to occur with respect
to any Plan which, with the giving of notice or lapse of time, or both, would constitute an
Event of Default under Section 11(h).

     (b) The present value of the aggregate benefit liabilities under each of the Plans
(other than Multiemployer Plans), determined as of the end of such Plan’s most recently
ended plan year on the basis of the actuarial assumptions specified for funding purposes in
such Plan’s most recent actuarial valuation report, did not exceed the aggregate current
value of the assets of such Plan allocable to such benefit liabilities. The term “benefit
liabilities” has the meaning specified in section 4001 of ERISA and the terms “current
value” and “present value” have the meaning specified in section 3 of ERISA.

     (c) Each Plan has complied with the applicable provisions of ERISA and the Code where
the failure to so comply would reasonably be expected to result in a Material Adverse
Effect.

     (d) The statement of assets and liabilities of each Plan and the statements of changes
in fund balance and in financial position, or the statement of changes in net assets
available for plan benefits, for the most recent plan year for which an accountant’s report
with respect to such Plan has been prepared, copies of which report are available for review
by the holders of the Notes, present fairly, in all material respects, the financial
condition of such Plan as at such date and the results of operations of such Plan for the
plan year ended on such date.

     (e) The execution and delivery of this Agreement and the issuance and sale of the Notes
hereunder will not involve any transaction that is subject to the prohibitions of section
406 of ERISA or in connection with which a tax could be imposed pursuant to section
4975(e)(1)(A)(D) of the Code.

     (f) Neither the MLP nor any ERISA Affiliate has incurred, or is reasonably expected to
incur, any Withdrawal Liability to any Multiemployer Plan which, when aggregated with all
other amounts required to be paid to Multiemployer Plans in connection with Withdrawal
Liability (as of the date of determination), would have a Material Adverse Effect.

     (g) Neither the MLP nor any ERISA Affiliate has received any notification that any
Multiemployer Plan is in reorganization, insolvent or has been terminated, within the
meaning of Title IV of ERISA, and no Multiemployer Plan is reasonably expected to be in
reorganization, to be insolvent or to be terminated within the meaning of Title IV of ERISA
the effect of which reorganization, insolvency or termination would be the occurrence of an
Event of Default under Section 11(h).

5.13 Private Offering by the Issuer.

10

 

          Neither the Issuer nor anyone acting on the Issuer’s behalf has offered the Notes or any
similar securities for sale to, or solicited any offer to buy any of the same from, or otherwise
approached or negotiated in respect thereof with, any Person other than the Purchasers, each of
which has been offered the Notes at a private sale for investment. Neither the Issuer nor anyone
acting on the Issuer’s behalf has taken, or will take, any action that would subject the issuance
or sale of the Notes to the registration requirements of Section 5 of the Securities Act or to the
registration requirements of any securities or blue sky laws of any applicable jurisdiction.

5.14 Use of Proceeds; Margin Regulations.

          The Issuer will apply the proceeds of the sale of the Notes in the manner described in the
Information Document. No part of the proceeds from the sale of the Notes will be used, directly or
indirectly, for the purpose of buying or carrying any margin stock within the meaning of Regulation
U of the FRB (12 CFR 221), or for the purpose of buying or carrying or trading in any securities
under such circumstances as to involve the Issuer in a violation of Regulation X of the FRB (12 CFR
224) or to involve any broker or dealer in a violation of Regulation T of the FRB (12 CFR 220).
Margin stock does not constitute more than 1% of the value of the consolidated assets of the Issuer
and the Issuer’s Subsidiaries and the Issuer has no present intention that margin stock will
constitute more than 1% of the value of such assets. As used in this Section, the terms “margin
stock” and “purpose of buying or carrying” shall have the meanings assigned to them in said
Regulation U.

5.15 Existing Indebtedness; Future Liens.

     (a) Except as described therein, Schedule 5.15 sets forth a complete and
correct list of all outstanding Indebtedness of the MLP, the Issuer and its Subsidiaries as
of [September 30], 2010, since which date there has been no Material change in the amounts
(other than to the extent of advances under the Credit Agreement), interest rates, sinking
funds, installment payments or maturities of the Indebtedness of the Issuer or its
Subsidiaries. None of the MLP, the Issuer or any Subsidiary is in default and no waiver of
default is currently in effect, in the payment of any principal or interest on any
Indebtedness of the MLP, the Issuer or any Subsidiary and no event or condition exists with
respect to any Indebtedness of the MLP, the Issuer or any Subsidiary that would permit (or
that with notice or the lapse of time, or both, would permit) one or more Persons to cause
such Indebtedness to become due and payable before its stated maturity or before its
regularly scheduled dates of payment.

     (b) Except as disclosed in Schedule 10.1, none of the MLP, the Issuer or any
Subsidiary has agreed or consented to cause or permit in the future (upon the happening of a
contingency or otherwise) any of its property, whether now owned or hereafter acquired, to
be subject to a Lien not permitted by Section 10.1.

     (c) Neither the MLP, the Issuer nor any Subsidiary is party to, or otherwise subject to
any provision contained in, any instrument evidencing Indebtedness of the MLP, the Issuer or
such Subsidiary, any agreement relating thereto or any other agreement (including, but not
limited to, its Organization Documents) which limits the amount of, or otherwise imposes
restrictions on the incurring of, Indebtedness of the

11

 

MLP, the Issuer or such Subsidiary, other than the debt agreements described in
Schedule 5.15.

5.16 [Reserved].

5.17 Status under Certain Statutes.

          None of the MLP, the Issuer or any Subsidiary is subject to regulation under the Investment
Company Act of 1940, as amended, the Public Utility Holding Company Act of 2005, as amended, the
ICC Termination Act, as amended, or the Federal Power Act, as amended.

5.18 Environmental Matters.

          Except for the matters set forth on Schedule 5.18 and other matters that, in the
aggregate, could not reasonably be expected to result in a Material Adverse Effect, neither the
MLP, the Issuer nor any of their Subsidiaries (a) has failed to comply with any Environmental Law
or to obtain, maintain or comply with any permit, license or other approval required under any
Environmental Law, (b) is subject to any Environmental Liability, (c) has received notice of any
claim with respect to any Environmental Liability or (d) knows of any basis for any Environmental
Liability.

6. REPRESENTATIONS OF THE PURCHASERS.

          Each Purchaser severally represents that it is purchasing the Notes for its own account or for
one or more separate accounts maintained by such Purchaser or for the account of one or more
pension or trust funds and not with a view to the distribution thereof, provided that the
disposition of such Purchaser’s or their property shall at all times be within such Purchaser’s or
their control. Each Purchaser understands that the Notes have not been registered under the
Securities Act and may be resold only if registered pursuant to the provisions of the Securities
Act or if an exemption from registration is available, except under circumstances where neither
such registration nor such an exemption is required by law, and that the Issuer is not required to
register the Notes.

Section 7.1 or Section 7.2 on a website established by the MLP and accessible by

8. PREPAYMENT OF THE NOTES.

8.1 No Scheduled Prepayments.

          No regularly scheduled prepayments are due on the Notes prior to their stated maturity.

8.2 Optional and Mandatory Prepayments.

     (a) The Issuer may, at its option, upon notice as provided in subsection (b) below,
prepay, at any time all, or from time to time any part of, the Notes, in an amount not less
than $5,000,000 in the aggregate in the case of a partial prepayment, at 100% of the
principal amount so prepaid, plus any LIBOR Breakage Amount.

     (b) The Issuer will give each holder of each series of Notes to be prepaid written
notice of each optional prepayment under this Section 8.2 not less than ten (10)
days and not more than sixty (60) days prior to the date fixed for such prepayment. Each
such notice shall specify such date, the aggregate principal amount of each series of Notes
to be prepaid on such date, the principal amount of each Note held by such holder to be
prepaid (determined in accordance with Section 8.4), and the interest to be paid on
the prepayment date with respect to such principal amount being prepaid. Two (2) Business
Days prior to such prepayment, the Issuer shall deliver to each holder of the Notes being
prepaid a certificate of a Responsible Officer acknowledging any LIBOR Breakage Amount owing
of which the Issuer has been notified by any holder of a Note.

     (c) Upon the incurrence or issuance after the date of this Agreement by the Issuer or
the MLP of any Indebtedness (other than revolving Indebtedness committed to the Issuer or
the MLP on the date of this Agreement) and Equity Interests, the Issuer shall prepay an
aggregate principal amount of Notes equal to 100% of all Net Cash Proceeds received
therefrom within three Business Days after the date of receipt thereof by the Issuer or the
MLP. Two (2) Business Days prior to such prepayment, the Issuer shall deliver to each
holder of the Notes being prepaid a certificate of a Responsible Officer acknowledging any
LIBOR Breakage Amount owing of which the Issuer has been notified by any holder of a Note.

8.3 Change of Control Prepayment Offer.

     (a) A “Change of Control Prepayment Event” occurs if, within the period of 120 days
from and including the date on which a Change of Control occurs, either (i) there are Rated
Securities outstanding at the time of such Change of Control and a Rating Downgrade in
respect of such Change of Control occurs or (ii) at such time there are no

16

 

Rated Securities and the MLP or the Issuer fails to obtain (whether by failing to seek
a rating or otherwise) either a rating of the Notes or any other unsecured and
unsubordinated Indebtedness of the MLP or the Issuer having a remaining maturity of five (5)
years or more (and which does not have the benefit of a guaranty from any Person other than
any such Person that at such time also guarantees the obligations of the Issuer under this
Agreement and the Notes) from a Rating Agency of at least Investment Grade (a “Negative
Rating Event”), in each case after giving pro forma effect to the transaction giving rise to
such Change of Control (such Change of Control and the related Rating Downgrade or, as the
case may be, Negative Rating Event, together (but not individually) constituting the Change
of Control Prepayment Event).

     (b) Promptly upon becoming aware that a Change of Control has occurred, and in any
event no later than fifteen (15) days after becoming aware of the Change of Control, the
Issuer shall give written notice of such fact to all holders of the Notes. Promptly upon
becoming aware that a Change of Control Prepayment Event has occurred, and not later than
thirty (30) days after becoming aware of the Change of Control Prepayment Event, the Issuer
shall give written notice (the “Issuer Notice”) of such fact to all holders of the Notes.
The Issuer Notice shall describe (i) the facts and circumstances of such Change of Control
Prepayment Event in reasonable detail, (ii) refer to this Section 8.3 and the rights
of the holders hereunder, and (iii) contain an offer by the Issuer to prepay the entire
unpaid principal amount of the Notes held by each holder at 100% of the principal amount of
such Notes at par (including any LIBOR Breakage Amount with respect to any Notes being
prepaid on a day other than a Floating Interest Payment Date), together with interest
accrued thereon to the date for such prepayment selected by the Issuer (the “Proposed
Prepayment Date”), which shall be specified in the Issuer Notice and which shall be a
Business Day not more than sixty (60) days after the Issuer Notice is given, should any
agreement to the contrary not be reached among the Issuer and each of the holders of the
Notes.

     (c) A holder of a Note may accept the offer to prepay made pursuant to this Section
8.3 by causing a notice of such acceptance to be delivered to the Issuer on or before
the Proposed Prepayment Date. A failure by a holder of a Note to respond to an offer to
prepay made pursuant to this Section 8.3 or to accept an offer by the Issuer to
prepay all of the Notes held by such holder prior to the Proposed Prepayment Date shall be
deemed to constitute rejection of such offer by such holder.

     (d) On any Proposed Prepayment Date, the entire unpaid principal amount of the Notes
held by each holder of the Notes which has accepted such prepayment offer, together with
interest accrued thereon to such date, but including any LIBOR Breakage Amount with respect
to any Notes being prepaid on a day other than a Floating Interest Payment Date, shall
become due and payable.

8.4 Allocation of Partial Prepayments.

          In the case of each partial prepayment of Notes of a series pursuant to Section 8.2,
the principal amount of the Notes of the series to be prepaid shall be allocated among all of the

17

 

Notes of such series at any time outstanding in proportion, as nearly as practicable, to the
respective unpaid principal amounts thereof not theretofore called for prepayment.

8.5 Maturity; Surrender, etc.

          In the case of each prepayment of Notes pursuant to this Section 8, the principal
amount of each Note to be prepaid shall mature and become due and payable on the date fixed for
such prepayment (which shall be a Business Day), together with interest on such principal amount
accrued to such date and the applicable LIBOR Breakage Amount, if any, and prepayment. From and
after such date, unless the Issuer shall fail to pay such principal amount when so due and payable,
together with the LIBOR Breakage Amount, if any, as aforesaid, interest on such principal amount
shall cease to accrue. Any Note paid or prepaid in full, after such payment and upon the written
request of the Issuer, shall be surrendered to the Issuer and canceled and shall not be reissued,
and no Note shall be issued in lieu of any prepaid principal amount of any Note.

8.6 Purchase of Notes.

          The Issuer will not and will not permit the MLP, the Issuer or any Subsidiary to purchase,
redeem, prepay or otherwise acquire, directly or indirectly, any of the outstanding Notes except
(a) upon the payment or prepayment of the Notes in accordance with the terms of this Agreement and
the Notes or (b) pursuant to a written offer to purchase any outstanding Notes made by the Issuer
or an Affiliate pro rata to the holders of Notes or any series thereof upon the same terms and
conditions. The Issuer will promptly cancel all Notes acquired by it or any Affiliate pursuant to
any payment, prepayment or purchase of Notes pursuant to any provision of this Agreement and no
Notes may be issued in substitution or exchange for any such Notes.

decrees applicable to it or its business or property, except in such instances in which (a) such
requirement of Law or order, writ, injunction or decree is being contested in good faith by
appropriate proceedings diligently conducted or (b) the failure to comply therewith could not
reasonably be expected to have a Material Adverse Effect.

18

 

9.2 Insurance.

          The Issuer and the MLP will, and will cause each of its Restricted Subsidiaries to, maintain

returns required to be filed in any jurisdiction and to pay and discharge when due all taxes shown
to be due and payable on such returns and all other taxes, assessments, governmental charges, or
levies imposed on them or any of their properties, assets, income or franchises, to the extent such
taxes and assessments have become due and payable and before they have become delinquent and all
claims for which sums have become due and payable that have or might become a Lien on properties or
assets of the Issuer or the MLP or any of its Restricted Subsidiaries, provided that neither the
Issuer, the MLP nor any Subsidiary thereof need pay any such tax or assessment or claims if (i) the
amount, applicability or validity thereof is contested by the Issuer, the MLP or such Restricted
Subsidiary on a timely basis in good faith and in appropriate proceedings, and the Issuer, the MLP
or such Restricted Subsidiary has established adequate reserves therefor in accordance with GAAP on
the books of the Issuer, the MLP or such Restricted Subsidiary or (ii) the non-filing of such
returns or nonpayment of all such taxes and assessments in the aggregate could not reasonably be
expected to have a Material Adverse Effect.

9.5 Existence, etc.

     The Issuer and the MLP will, and will cause each of its Restricted Subsidiaries to:

     (a) Preserve, renew and maintain in full force and effect its legal existence and good
standing under the Laws of the jurisdiction of its organization except in a transaction
permitted by Section 10.4 or Section 10.5 or where the failure to so
preserve would not have a Material Adverse Effect and except that nothing herein shall
prevent any change in Business Entity form of any Subsidiary of the MLP, and

     (b) take reasonable action to maintain permits, licenses and franchises necessary in
the normal conduct of its business, except to the extent that failure to do so could not
reasonably be expected to have a Material Adverse Effect.

19

 

9.6 Books and Records.

          The Issuer and the MLP will, and will cause its Restricted Subsidiaries to, (a) maintain
proper books of record and account, in which full, true and correct entries in conformity with GAAP

and business; and (b) maintain such books of record and account in conformity with the applicable
material requirements of any Governmental Authority having regulatory jurisdiction over the Issuer,
the MLP or such Restricted Subsidiary, as the case may be.

the Credit Agreement) (i) guarantees Indebtedness in respect of the Credit Agreement or (ii)
becomes an “Additional Borrower” under the Credit Agreement and assumes liability for any portion
of the Indebtedness of any other “Borrower” under the Credit Agreement, to enter into a Subsidiary
Guaranty concurrently therewith and as a part thereof to deliver to each of the holders a

representations and warranties in Sections 5.2, 5.6, and 5.7, with respect
to such Subsidiary and such Subsidiary Guaranty, as applicable.

9.8 Use of Proceeds.

          The Issuer will use the proceeds of the Notes in the manner described in Section the
Information Document.

9.9 Ranking of Notes.

     (a) The Notes and the Issuer’s obligations under this Agreement will rank at least pari
passu with all of the Issuer’s outstanding unsecured Senior Indebtedness; provided, that
during any period that the Credit Agreement is secured, the Notes and the Issuer’s
obligations under this Agreement will rank at least pari passu with all of the Issuer’s
obligations under the Credit Agreement.

     (b) The Issuer and the MLP will, if either of them or any Subsidiary shall create any
Lien upon any of its property or assets, whether now owned or hereafter acquired, in favor
of the lenders or other creditors who are party to the Credit Agreement (unless prior
written consent to the creation thereof shall have been obtained from the Required Holders),
make or cause to be made effective provision whereby the Notes will be secured by such Lien
equally and ratably with all other Indebtedness thereby secured.

12. REMEDIES ON DEFAULT, ETC.

12.1 Acceleration.

     (a) If an Event of Default described in paragraph (f) of Section 11 (other than
an Event of Default described in clause (i) of paragraph (f) or described in clause (iii)(C)
of paragraph (f) by virtue of the fact that such paragraph encompasses clause (i) of
paragraph (f)) has occurred, all the Notes then outstanding shall automatically become
immediately due and payable.

     (b) If any other Event of Default has occurred and is continuing, holders of more than
50% in principal amount of the Notes at the time outstanding may at any time at its or their
option, by notice or notices to the Issuer, declare all the Notes then outstanding to be
immediately due and payable.

     (c) If any Event of Default described in paragraph (a) of Section 11 has
occurred and is continuing, the holder or holders of not less than $50,000,000 in principal
amount of the Notes at the time outstanding affected by such Event of Default may at any
time, at its or their option, by notice or notices to the Issuer, declare all the Notes held
by it or them to be immediately due and payable.

          Upon any Notes becoming due and payable under this Section 12.1, whether automatically
or by declaration, such Notes will forthwith mature and the entire unpaid principal amount of such
Notes, plus (x) all accrued and unpaid interest thereon (including, but not limited to, interest
accrued thereon at the Default Rate) and (y) any applicable LIBOR Breakage Amount, determined in
respect of such principal amount (to the full extent permitted by applicable law), shall all be
immediately due and payable, in each and every case without presentment, demand, protest or further
notice, all of which are hereby waived. The Issuer acknowledges, and the parties hereto agree,
that each holder of a Note has the right to maintain its investment in the Notes free from
repayment by the Issuer (except as herein specifically provided for) and that the provision for
payment of a LIBOR Breakage Amount, by the Issuer in the event that the Notes are prepaid or are
accelerated as a result of an Event of Default, is intended to provide compensation for the
deprivation of such right under such circumstances.

32

 

12.2 Other Remedies.

          If any Default or Event of Default has occurred and is continuing, and irrespective of whether
any Notes have become or have been declared immediately due and payable under Section 12.1,
the holder of any Note at the time outstanding may proceed to protect and enforce the rights of
such holder by an action at law, suit in equity or other appropriate proceeding, whether for the
specific performance of any agreement contained herein or in any Note, or for an injunction against
a violation of any of the terms hereof or thereof, or in aid of the exercise of any power granted
hereby or thereby or by law or otherwise.

12.3 Rescission.

          At any time after any Notes have been declared due and payable pursuant to paragraph (b) or
(c) of Section 12.1, the holders of more than 50% in principal amount of the Notes then
outstanding, by written notice to the Issuer, may rescind and annul any such declaration and its
consequences if (a) the Issuer has paid all overdue interest on the Notes, all principal of and any
LIBOR Breakage Amount on any Notes that are due and payable and are unpaid other than by reason of
such declaration, and all interest on such overdue principal and any LIBOR Breakage Amount and (to
the extent permitted by applicable law) any overdue interest in respect of the Notes, at the
Default Rate, (b) neither the Issuer nor any other Person shall have paid any amounts which have
become due solely by reason of such declaration, (c) all Events of Default and Defaults, other than
non-payment of amounts that have become due solely by reason of such declaration, have been cured
or have been waived pursuant to Section 17, and (d) no judgment or decree has been entered
for the payment of any monies due pursuant hereto or to the Notes. No rescission and annulment
under this Section 12.3 will extend to or affect any subsequent Event of Default or Default
or impair any right consequent thereon.

12.4 No Waivers or Election of Remedies, Expenses, etc.

          No course of dealing and no delay on the part of any holder of any Note in exercising any
right, power or remedy shall operate as a waiver thereof or otherwise prejudice such holder’s
rights, powers or remedies. No right, power or remedy conferred by this Agreement or by any Note
or the Subsidiary Guaranty or the Parent Guaranty upon any holder thereof shall be exclusive of any
other right, power or remedy referred to herein or therein or now or hereafter available at law, in
equity, by statute or otherwise. Without limiting the obligations of the Issuer under Section
15, the Issuer will pay to the holder of each Note on demand such further amount as shall be
sufficient to cover all costs and expenses of such holder incurred in any enforcement or collection
under this Section 12, including, without limitation, reasonable attorneys’ fees, expenses
and disbursements.

13. REGISTRATION; EXCHANGE; SUBSTITUTION OF NOTES.

13.1 Registration of Notes.

registration of transfers of Notes. The name and address of each holder of one or more Notes, each
transfer thereof and the name and address of each transferee of one or more Notes shall be
registered in such register. Prior to due presentment for registration of transfer, the

33

 

Person in whose name any Note shall be registered shall be deemed and treated as the owner and
holder thereof for all purposes hereof, and the Issuer shall not be affected by any notice or
knowledge to the contrary. The Issuer shall give to any holder of a Note that is an Institutional
Investor, promptly upon request therefor, a complete and correct copy of the names and addresses of
all registered holders of Notes.

13.2 Transfer and Exchange of Notes.

          Upon surrender of any Note at the principal executive office of the Issuer for registration of
transfer or exchange (and in the case of a surrender for registration of transfer, duly endorsed or
accompanied by a written instrument of transfer duly executed by the registered holder of such Note
or his attorney duly authorized in writing and accompanied by the address for notices of each
transferee of such Note or part thereof), the Issuer shall execute and deliver within ten (10)
days, at the Issuer’s expense (except as provided below), one or more new Notes (as requested by
the holder thereof) of the same series in exchange therefor, in an aggregate principal amount equal
to the unpaid principal amount of the surrendered Note. Each such new Note shall be payable to
such Person as such holder may request and shall be substantially in the form of Note specified for
the Notes of such series, if any. Each such new Note shall be dated and bear interest from the
date to which interest shall have been paid on the surrendered Note or dated the date of the
surrendered Note if no interest shall have been paid thereon. The Issuer may require payment of a
sum sufficient to cover any stamp tax or governmental charge imposed in respect of any such
transfer of Notes. Notes shall not be transferred in denominations of less than $100,000, provided
that if necessary to enable the registration of transfer by a holder of its entire holding of
Notes, one Note may be in a denomination of less than $100,000.

13.3 Replacement of Notes.

          Upon receipt by the Issuer of evidence reasonably satisfactory to it of the ownership of and
the loss, theft, destruction or mutilation of any Note (which evidence shall be, in the case of an
Institutional Investor, notice from such Institutional Investor of such ownership and such loss,
theft, destruction or mutilation), and

     (a) in the case of loss, theft or destruction, of indemnity reasonably satisfactory to
it (provided that if the holder of such Note is, or is a nominee for, an original Purchaser
or another Institutional Investor holder of a Note with a minimum net worth of at least
US$50,000,000, such Person’s own unsecured agreement of indemnity shall be deemed to be
satisfactory), or

     (b) in the case of mutilation, upon surrender and cancellation thereof,

the Issuer at its own expense shall execute and deliver within ten (10) days, in lieu thereof, a
new Note of the same series, dated and bearing interest from the date to which interest shall have
been paid on such lost, stolen, destroyed or mutilated Note or dated the date of such lost, stolen,
destroyed or mutilated Note if no interest shall have been paid thereon.

interest becoming due and payable on the Notes shall be made in Houston, Texas at the principal
office of the Purchaser in such jurisdiction. The Issuer may at any time, by notice to each holder

trust company in such jurisdiction.

14.2 Home Office Payment.

          So long as any Purchaser or its nominee shall be the holder of any Note, and notwithstanding

method and at the address specified for such purpose below such Purchaser’s name in Schedule
A, or by such other method or at such other address as such Purchaser shall have from time to
time specified to the Issuer in writing for such purpose, without the presentation or surrender of
such Note or the making of any notation thereon, except that upon written request of the Issuer
made concurrently with or reasonably promptly after payment or prepayment in full of any Note, such
Purchaser shall surrender such Note for cancellation, reasonably promptly after any such request,
to the Issuer at the principal executive office or other place of payment most recently designated
by the Issuer pursuant to Section 14.1. Prior to any sale or other disposition of any Note
held by a Purchaser or its nominee, such Purchaser will, at its election, either endorse thereon
the amount of principal paid thereon and the last date to which interest has been paid thereon or
surrender such Note to the Issuer in exchange for a new Note or Notes pursuant to Section
13.2. The Issuer will afford the benefits of this Section 14.2 to any Institutional
Investor that is the direct or indirect transferee of any Note purchased by a Purchaser under this
Agreement and that has made the same agreement relating to such Note as the Purchasers have made in
this Section 14.2.

(other than those, if any, retained by any Purchaser or other holder in connection with its
purchase of the Notes).

15.2 Survival.

          The obligations of the Issuer under this Section 15 will survive the payment or
transfer of any Note, the enforcement, amendment or waiver of any provision of this Agreement or

thereof, and may be relied upon by any subsequent holder of a Note, regardless of any investigation
made at any time by or on behalf of such Purchaser or any other holder of a Note. All statements
contained in any certificate or other instrument delivered by or on behalf of the Issuer pursuant
to this Agreement shall be deemed representations and warranties of the Issuer under this
Agreement. Subject to the preceding sentence, this Agreement and the Notes embody the entire
agreement and understanding between each Purchaser and the Issuer and supersede all prior
agreements and understandings relating to the subject matter hereof.

17. AMENDMENT AND WAIVER.

17.1 Requirements.

          This Agreement, the Notes, the Subsidiary Guaranty and the Parent Guaranty may be amended, and
the observance of any term hereof or thereof may be waived (either retroactively or prospectively),
with (and only with) the written consent of the Issuer (and each Subsidiary Guarantor party
thereto, in the case of any Subsidiary Guaranty, and the MLP, in the case of the Parent Guaranty)
and the Required Holders, except that (a) no amendment or waiver of any of the provisions of
Section 1, 2, 3, 4, 5, 6 or 21 hereof, or
any defined term (as it is used therein), will be effective as to any Purchaser unless consented to
by such Purchaser in writing, and (b) no such amendment or waiver may, without the written consent
of the holder of each Note at the time outstanding affected thereby, (i) subject to the provisions
of Section 12 relating to acceleration or rescission, change the amount or time of any
prepayment or payment of principal of, or reduce the rate or change the time of payment or method
of computation of

36

 

interest or of the LIBOR Breakage Amount on, the Notes, (ii) change the percentage of the
principal amount of the Notes the holders of which are required to consent to any such amendment or
waiver, or (iii) amend any of Sections 8, 11(a), 12, 17 or
20.

17.2 [Reserved].

17.3 Binding Effect, etc.

          Any amendment or waiver consented to as provided in this Section 17 applies equally to
all holders of Notes and is binding upon them and upon each future holder of any Note and upon the
Issuer and the MLP without regard to whether such Note has been marked to indicate such amendment
or waiver. No such amendment or waiver will extend to or affect any obligation, covenant,
agreement, Default or Event of Default not expressly amended or waived or impair any right
consequent thereon. No course of dealing between the Issuer or the MLP and the holder of any Note
or any delay in exercising any rights hereunder or under any Note shall operate as a waiver of any
rights of any holder of such Note. As used herein, the term “Agreement” and references thereto
shall mean this Note Purchase Agreement, dated as of [                    ], 2010, as it may from time to
time be amended or supplemented.

17.4 Notes held by Issuer, etc.

          Solely for the purpose of determining whether the holders of the requisite percentage of the
aggregate principal amount of Notes then outstanding approved or consented to any amendment, waiver
or consent to be given under this Agreement or the Notes, or have directed the taking of any action
provided herein or in the Notes to be taken upon the direction of the holders of a specified
percentage of the aggregate principal amount of Notes then outstanding, Notes directly or
indirectly owned by the Issuer or any of its Subsidiaries shall be deemed not to be outstanding.

18. NOTICES.

          All notices and communications provided for hereunder shall be in writing and sent (a) by
facsimile if the sender on the same day sends a confirming copy of such notice by a recognized
overnight delivery service (charges prepaid) or (b) by a recognized overnight delivery service
(with charges prepaid). Any such notice must be sent:

     (i) if to any Purchaser or its nominee, to such Purchaser or nominee at the
address specified for such communications in Schedule A, or at such other
address as such Purchaser or nominee shall have specified to the Issuer in writing,

     (ii) if to any other holder of any Note, to such holder at such address as such
other holder shall have specified to the Issuer in writing, or

     (iii) if to the Issuer or the MLP, at the address set forth at the beginning
hereof to the attention of the treasurer, or at such other address as the Issuer
shall have specified to the holder of each Note in writing.

Notices under this Section 18 will be deemed given only when actually received.

37

 

19. REPRODUCTION OF DOCUMENTS.

          This Agreement and all documents relating thereto, including (a) consents, waivers and
modifications that may hereafter be executed, (b) documents received by any Purchaser at the
Closing (except the Notes themselves), and (c) financial statements, certificates and other
information previously or hereafter furnished to any Purchaser, may be reproduced by such Purchaser
by any photographic, photostatic, microfilm, microcard, miniature photographic or other similar
process and such Purchaser may destroy any original document so reproduced. Each of the Issuer and
the MLP agrees and stipulates that, to the extent permitted by applicable law, any such
reproduction shall be admissible in evidence as the original itself in any judicial or
administrative proceeding (whether or not the original is in existence and whether or not such
reproduction was made by such Purchaser in the regular course of business) and any enlargement,
facsimile or further reproduction of such reproduction shall likewise be admissible in evidence.
This Section 19 shall not prohibit the Issuer, the MLP or any holder of a Note from
contesting any such reproduction to the same extent that it could contest the original, or from
introducing evidence to demonstrate the inaccuracy of any such reproduction.

20. CONFIDENTIAL INFORMATION.

          For the purposes of this Section 20, “Confidential Information” means information
delivered to any Purchaser by or on behalf of the Issuer and the MLP and its Subsidiaries in
connection with the transactions contemplated by or otherwise pursuant to this Agreement that is
proprietary in nature and that was clearly marked or labeled or otherwise adequately identified
when received by such Purchaser as being confidential information of the Issuer, the MLP or such
Subsidiary, provided that such term does not include information that (a) was publicly known or
otherwise known to such Purchaser prior to the time of such disclosure, (b) subsequently becomes
publicly known through no act or omission by such Purchaser or any person acting on such
Purchaser’s behalf, (c) otherwise becomes known to such Purchaser other than through disclosure by
the Issuer, the MLP or such Subsidiary or (d) constitutes financial statements delivered to such
Purchaser under Section 7.1 that are otherwise publicly available. Each Purchaser will
maintain the confidentiality of such Confidential Information in accordance with procedures adopted
by such Purchaser in good faith to protect confidential information of third parties delivered to
such Purchaser, provided that such Purchaser may deliver or disclose Confidential Information to
(i) its directors, trustees, officers, employees, agents, attorneys and affiliates (to the extent
such disclosure reasonably relates to the administration of the investment represented by its
Notes), (ii) its financial advisors and other professional advisors who agree to hold confidential
the Confidential Information substantially in accordance with the terms of this Section 20,
(iii) any other holder of any Note, (iv) any Institutional Investor to which it sells or offer to
sell such Note or any part thereof or any participation therein (if such Person has agreed in
writing prior to its receipt of such Confidential Information to be bound by the provisions of this
Section 20), (v) any Person from which it offers to purchase any security of the Issuer or
the MLP (if such Person has agreed in writing prior to its receipt of such Confidential Information
to be bound by the provisions of this Section 20), (vi) any federal or state regulatory
authority having jurisdiction over such Purchaser, (vii) the National Association of Insurance
Commissioners or any similar organization, or any Rating Agency that requires access to information
about its investment portfolio or (viii) any

38

 

other Person to which such delivery or
disclosure may be necessary or appropriate (w) to effect compliance with any law, rule,
regulation or order applicable to such Purchaser, (x) in response to any subpoena or other legal
process, (y) in connection with any litigation to which such Purchaser is a party or (z) if an
Event of Default has occurred and is continuing, to the extent it has may reasonably determine such
delivery and disclosure to be necessary or appropriate in the enforcement or for the protection of
the rights and remedies under such Purchaser’s Notes and this Agreement. Each holder of a Note, by
its acceptance of a Note, will be deemed to have agreed to be bound by and to be entitled to the
benefits of this Section 20 as though it were a party to this Agreement. On reasonable
request by the Issuer in connection with the delivery to any holder of a Note of information
required to be delivered to such holder under this Agreement or requested by such holder (other
than a holder that is a party to this Agreement or its nominee), such holder will enter into an
agreement with the Issuer and the MLP embodying the provisions of this Section 20.

21. SUBSTITUTION OF PURCHASER.

          Each Purchaser shall have the right to substitute any one of its Affiliates as the purchaser
of the Notes that it has agreed to purchase hereunder, by written notice to the Issuer, which
notice shall be signed by both such Purchaser and such Affiliate, shall contain such Affiliate’s
agreement to be bound by this Agreement and shall contain a confirmation by such Affiliate of the
accuracy with respect to it of the representations set forth in Section 6. Upon receipt of
such notice, any reference to such Purchaser in this Agreement (other than in this Section
21) shall be deemed to refer to such Affiliate in lieu of such original Purchaser. In the
event that such Affiliate is so substituted as a Purchaser hereunder and such Affiliate thereafter
transfers to such original Purchaser all of the Notes then held by such Affiliate, upon receipt by
the Issuer of notice of such transfer, any reference to such Affiliate as a “Purchaser” in this
Agreement (other than in this Section 21) shall no longer be deemed to refer to such
Affiliate, but shall refer to such original Purchaser, and such original Purchaser shall again have
all the rights of an original holder of the Notes under this Agreement.

22. MISCELLANEOUS.

22.1 Successors and Assigns.

          All covenants and other agreements contained in this Agreement by or on behalf of any of the
parties hereto bind and inure to the benefit of their respective successors and assigns (including,
without limitation, any subsequent holder of a Note) whether so expressed or not.

22.2 Jurisdiction and Process; Waiver of Jury Trial.

     (a) Each of the Issuer and the MLP irrevocably submits to the non-exclusive
jurisdiction of any New York or federal court sitting in New York City, Borough of
Manhattan, over any suit, action or proceeding arising out of or relating solely to this
Agreement or the Notes. To the fullest extent permitted by applicable law, each of the
Issuer and the MLP irrevocably waives and agrees not to assert, by way of motion, as a
defense or otherwise, any claim that it is not subject to the jurisdiction of any such
court,

39

 

any objection that it may now or hereafter have to the laying of the venue of any such
suit, action or proceeding brought in any such court and any claim that any such suit,
action or proceeding brought in any such court has been brought in an inconvenient forum.

     (b) Each of the Issuer and the MLP agrees, to the fullest extent permitted by
applicable law, that a final judgment in any suit, action or proceeding of the nature
referred to in Section 22.2(a) brought in any such court shall be conclusive and
binding upon it subject to rights of appeal, as the case may be, and may be enforced in the
courts of the United States of America or the State of New York (or any other courts to the
jurisdiction of which it or any of its assets is or may be subject) by a suit upon such
judgment.

     (c) Each of the Issuer and the MLP consents to process being served in any suit, action
or proceeding solely of the nature referred to in Section 22.2(a) by mailing a copy
thereof by registered or certified or priority mail, postage prepaid, return receipt
requested, or delivering a copy thereof in the manner for delivery of notices specified in
Section 18, to it. Each of the Issuer and the MLP agrees that such service upon
receipt (i) shall be deemed in every respect effective service of process upon it in any
such suit, action or proceeding and (ii) shall, to the fullest extent permitted by
applicable law, be taken and held to be valid personal service upon and personal delivery to
it. Notices hereunder shall be conclusively presumed received as evidenced by a delivery
receipt furnished by the United States Postal Service or any reputable commercial delivery
service.

     (d) Nothing in this Section 22.2 shall affect the right of any holder of a Note
to serve process in any manner permitted by law, or limit any right that the holders of any
of the Notes may have to bring proceedings against the Issuer or the MLP in the courts of
any appropriate jurisdiction or to enforce in any lawful manner a judgment obtained in one
jurisdiction in any other jurisdiction.

     (e) THE PARTIES HERETO WAIVE TRIAL BY JURY IN ANY ACTION BROUGHT ON OR WITH RESPECT TO
THIS AGREEMENT, THE NOTES OR ANY OTHER DOCUMENT EXECUTED IN CONNECTION HEREWITH OR
THEREWITH.

22.3 Payments Due on Non-Business Days.

          Anything in this Agreement or the Notes to the contrary notwithstanding (but without limiting
the requirement in Section 8.5 that any optional prepayment specify a Business Day as the
date fixed for such prepayment), any payment of principal of or LIBOR Breakage Amount or interest
on any Note that is due on a date other than a Business Day shall be made on the next succeeding
Business Day without including the additional days elapsed in the computation of the interest
payable on such next succeeding Business Day; provided that if the maturity date of any Note is a
date other than a Business Day, the payment otherwise due on such maturity date shall be made on
the next succeeding Business Day and shall include the additional days elapsed in the computation
of interest payable on such next succeeding Business Day.

40

 

22.4 Severability.

          Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall,
as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability
without invalidating the remaining provisions hereof, and any such prohibition or unenforceability
in any jurisdiction shall (to the full extent permitted by law) not invalidate or render
unenforceable such provision in any other jurisdiction.

22.5 Construction.

          Each covenant contained herein shall be construed (absent express provision to the contrary)
as being independent of each other covenant contained herein, so that compliance with any one
covenant shall not (absent such an express contrary provision) be deemed to excuse compliance with
any other covenant. Where any provision herein refers to action to be taken by any Person, or
which such Person is prohibited from taking, such provision shall be applicable whether such action
is taken directly or indirectly by such Person.

22.6 Counterparts.

          This Agreement may be executed in any number of counterparts, each of which shall be an
original but all of which together shall constitute one instrument. Each counterpart may consist
of a number of copies hereof, each signed by less than all, but together signed by all, of the
parties hereto.

22.7 Governing Law.

          This Agreement shall be construed and enforced in accordance with, and the rights of the
parties shall be governed by, the law of the State of New York, excluding choice-of-law principles
of the law of such State that would require the application of the laws of a jurisdiction other
than such State.

22.8 GAAP.

          (a) Generally. All accounting terms not specifically or completely defined herein
shall be construed in conformity with, and all financial data (including financial ratios and other
financial calculations) required to be submitted pursuant to this Agreement shall be prepared in
conformity with, GAAP applied on a consistent basis, as in effect from time to time, applied in a
manner consistent with that used in preparing the audited financial statements, except as otherwise
specifically prescribed herein.

          (b) Changes in GAAP. Except as otherwise expressly provided herein, all terms of an
accounting or financial nature shall be construed in accordance with GAAP, as in effect from time
to time; provided that, if the MLP notifies the holders that the MLP requests an amendment to any
provision hereof to eliminate the effect of any change occurring after the date hereof in GAAP or
in the application thereof on the operation of or calculation of compliance with such provision (or
if the Required Holders notify the MLP that the Required Holders

41

 

request an amendment to any provision hereof for such purpose), regardless of whether any such
notice is given before or after such change in GAAP or in the application thereof, then such
provision shall be interpreted on the basis of GAAP as in effect and applied immediately before
such change shall have become effective until such notice shall have been withdrawn or such
provision amended in accordance herewith.
