[Reverse of Security]

     This Security is one of a duly authorized issue of securities of the Company (herein called
the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of
February 8, 2001 (herein called the “Base Indenture”, between the Company and The Bank of New York
Mellon, as Trustee (the “Trustee”, which term includes any successor trustee under the Base
Indenture), as amended and supplemented by the First Supplemental Indenture, dated as of October
13, 2005, between the Company and the Trustee (the “First Supplemental Indenture”), as further
amended and supplemented by the Second Supplemental Indenture, dated as of March 14, 2008, between
the Company and the Trustee (the “Second Supplemental Indenture”) and as further amended and
supplemented by the Third Supplemental Indenture, dated February 22, 2011 between the Company and
the Trustee (the “Third Supplemental Indenture”, together with the Base Indenture, the First
Supplemental Indenture and the Second Supplemental Indenture, the “Indenture”). Reference is hereby
made to the Indenture for a statement of the respective rights, limitations of rights, duties and
immunities thereunder of the Company, the Trustee and the Holders of the Securities, and of the
terms upon which the Securities are, and are to be authenticated and delivered. This Security is
one of a series designated on the face hereof initially limited in aggregate principal amount to
$350,000,000.

     The Securities of this series are subject to redemption upon not less than 30 days’ and not
more than 60 days’ notice by mail, as a whole or in part, at the election of the Company, from time
to time. If the Securities of this series are redeemed before the date that is three months prior
to the maturity date of the Securities of this series, the Securities shall be redeemed at a
redemption price equal to the greater of (i) 100% of the principal amount of such Securities then
outstanding to be redeemed, or (ii) the sum of the present values of the remaining scheduled
payments of principal and interest on the Securities to be redeemed (not including any portion of
such payments of interest accrued to the date of redemption) discounted to the date of redemption
on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the
applicable Treasury Rate plus 15 basis points (0.15%), plus, in each case, accrued and unpaid
interest on the principal amount being redeemed to, but excluding, the Redemption Date, provided,
however, that interest installments whose Stated Maturity is on or prior to such Redemption Date
shall be payable to the Holders of such Securities, or one or more Predecessor Securities, of
record at the close of business on the relevant Record Dates referred to on the face hereof, all as
provided in the Indenture. If the Securities of this series are redeemed on or after the date that
is three months prior to the maturity date of the Securities of this series, the Securities may be
redeemed at a redemption price equal to 100% of the principal amount of the Securities then
outstanding to be redeemed, plus accrued and unpaid interest on the principal amount being redeemed
to, but excluding, the Redemption Date, provided, however that interest installments whose Stated
Maturity is on or prior to such Redemption Date shall be payable to the Holders of such Securities,
or one or more Predecessor Securities, of record at the close of business on the relevant Record
Dates referred to on the face hereof, all as provided in the Indenture.

     For purposes of the redemption provisions, the following terms are applicable:

     “Comparable Treasury Issue” shall mean the United States Treasury security selected by the
Quotation Agent as having an actual or interpolated maturity comparable to the remaining term of
the Securities to be redeemed 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 such Securities.

     “Comparable Treasury Price” shall mean, with respect to any Redemption Date: (i) the average
of four Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest
and lowest such Reference Treasury Dealer Quotations; (ii) if the Company obtains fewer than four
such Reference Treasury Dealer Quotations, the average of all such Reference Treasury Dealer
Quotations; or (iii) if only one such Reference Treasury Dealer Quotation is received, such
Reference Treasury Dealer Quotation.

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

3

 

     “Reference Treasury Dealer” means: (i) Goldman, Sachs & Co., J.P. Morgan Securities LLC and
Merrill Lynch, Pierce, Fenner & Smith Incorporated (or their respective affiliates that are Primary
Treasury Dealers) and their respective successors; provided, however, that if any of the foregoing
shall cease to be a primary U.S. Government securities dealer in the United States of America (a
“Primary Treasury Dealer”), the Company shall substitute therefor another Primary Treasury Dealer;
and (ii) one other Primary Treasury Dealer 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 Company, 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 Company by the Reference Treasury Dealer at 3:30 p.m. (New York City time)
on the third Business Day preceding such Redemption Date.

     “Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the
semi-annual equivalent yield to actual or interpolated maturity (on a day count basis) 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 of such Redemption Date.

     In the event of redemption of this Security in part only, a new Security or Securities of this
series for the unredeemed portion hereof shall be issued in the name of the holder hereof upon the
cancellation hereof.

     If a Change of Control Triggering Event occurs, unless the Company has exercised its option to
redeem the Securities as described above, the Company shall be required to make an offer (the
“Change of Control Offer”) to each Holder of the Securities to repurchase all or any part (equal to
$2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Securities on the
terms set forth herein. In the Change of Control Offer, the Company shall be required to offer
payment in cash equal to 101% of the aggregate principal amount of Securities repurchased, plus
accrued and unpaid interest, if any, on the Securities repurchased to the date of repurchase (the
“Change of Control Payment”). Within 30 days following any Change of Control Triggering Event or,
at the Company’s option, prior to the date of the consummation of any Change of Control, but after
public announcement of the transaction that constitutes or may constitute the Change of Control,
the Company shall be required to mail a notice to Holders of Securities, with a copy to the
Trustee, describing the transaction or transactions that constitute or may constitute the Change of
Control Triggering Event and offering to repurchase the Securities on the date specified in the
notice, which date shall be no earlier than 30 days and no later than 60 days from the date such
notice is mailed (the “Change of Control Payment Date”) pursuant to the procedures described in
such notice and in conformity with the Indenture.

     The notice shall, if mailed prior to the date of the consummation of the Change of Control,
state that the offer to purchase is conditioned on the Change of Control Triggering Event occurring
on or prior to the payment date specified in the notice.

     On the Change of Control Payment Date, the Company shall be required, to the extent lawful:
(a) to accept for payment all Securities or portions of Securities properly tendered pursuant to
the Change of Control Offer; (b) to deposit with the paying agent an amount equal to the Change of
Control Payment in respect of all Securities or portions of Securities properly tendered; and (c)
to deliver or cause to be delivered to the Trustee the Securities properly accepted together with
an Officers’ Certificate stating the aggregate principal amount of Securities or portions of
Securities being repurchased.

     The Company shall not be required to make the Change of Control Offer upon a Change of Control
Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in
compliance with the requirements for an offer made by the Company and such third party purchases
all Securities properly tendered and not withdrawn under its offer. In addition, the Company shall
not repurchase any Securities if there has occurred and is continuing on the Change of Control
Payment Date an Event of Default under the Indenture, other than a default in the payment of the
Change of Control Payment upon a Change of Control Triggering Event.

4

 

     The Company shall comply with the requirements of Rule 14e-1 under the Securities Exchange Act
of 1934, as amended (the “Exchange Act”), and any other securities laws and regulations thereunder
to the extent those laws and regulations are applicable in connection with the repurchase of the
Securities 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 the Securities, the Company shall comply with those securities laws and regulations
and shall not be deemed to have breached its obligations under the Indenture or the Change of
Control Offer provisions of the Securities by virtue of any such conflicts.

For purposes of the Change of Control Offer provisions, the following terms are applicable:

     “Change of Control” means the occurrence of any of the following: (i) the consummation of any
transaction (including, without limitation, any merger or consolidation) the result of which is
that any “person” as the term is defined in Section 13(d)(3) of the Exchange Act) (other than the
Company or one of its subsidiaries) becomes the beneficial owner (as defined in Rules 13d-3 and
13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the Company’s Voting
Stock or other Voting Stock into which the Company’s Voting Stock is reclassified, consolidated,
exchanged or changed, measured by voting power rather than number of shares; (ii) the direct or
indirect sale, transfer, conveyance or other disposition (other than by way of merger or
consolidation), in one or more series of related transactions, of all or substantially all of the
Company’s assets and the assets of its subsidiaries, taken as a whole, to one or more Persons
(other than the Company or one of its subsidiaries); or (iii) the first day on which a majority of
the members of the Board of Directors are not Continuing Directors. Notwithstanding the foregoing,
a transaction shall not be deemed to involve a Change of Control if (1) the Company becomes a
direct or indirect wholly-owned subsidiary of a holding company and (2)(A) the direct or indirect
holders of the Voting Stock of such holding company immediately following that transaction are
substantially the same as the holders of the Company’s Voting Stock immediately prior to that
transaction or (B) immediately following that transaction no Person (other than a holding company
satisfying the requirements of this sentence) is the beneficial owner, directly or indirectly, of
more than 50% of the Voting Stock of such holding company.

     “Change of Control Triggering Event” means the occurrence of both a Change of Control and a
Rating Event with respect to the Securities.

     “Continuing Directors” means, as of any date of determination, any member of the Company’s
Board of Directors who: (i) was a member of such Board of Directors on the date the Securities were
issued; or (ii) was nominated for election, elected or appointed to such Board of Directors with
the approval of a majority of the Continuing Directors who were members of such Board of Directors
at the time of such nomination, election or appointment (either by a specific vote or by approval
of the Company’s proxy statement in which such member was named as a nominee for election as a
director, without objection to such nomination).

     “Investment Grade Rating” means a rating equal to or higher than Baa3 (or the equivalent) by
Moody’s and BBB- (or the equivalent) by S&P, and the equivalent investment grade credit rating from
any additional rating agency or rating agencies selected by the Company.

     “Moody’s” means Moody’s Investors Service Inc.

     “Person” has the meaning set forth in the Indenture and includes a “person” or “group” as
these terms are used in Section 13(d)(3) of the Exchange Act.

     “Rating Agencies” means (i) each of Moody’s and S&P; and (ii) if either of Moody’s or S&P
ceases to rate the Securities or fails to make a rating of the Securities publicly available for
reasons outside of the Company’s control, a “nationally recognized statistical rating
organization” within the meaning of Rule 15c3-1(c)(2)(vi)(F) under the Exchange Act selected by the
Company (as certified by a Board Resolution) as a replacement agency for Moody’s or S&P, or both of
them, as the case may be.

5

 

     “Rating Event” means the rating on the Securities is lowered by each of the Rating Agencies
and the Securities are rated below an Investment Grade Rating by each of the Rating Agencies on any
day within the 60-day period (which 60-day period shall be extended so long as the rating of the
Securities is under publicly announced consideration for a possible downgrade by any of the Rating
Agencies) after the earlier of: (i) the occurrence of a Change of Control; and (ii) public notice
of the occurrence of a Change of Control or the Company’s intention to effect a Change of Control;
provided, however, that a Rating Event otherwise arising by virtue of a particular reduction in
rating shall not be deemed to have occurred in respect of a particular Change of Control (and thus
shall not be deemed a Rating Event for purposes of the definition of Change of Control Triggering
Event) if the Rating Agencies making the reduction in rating to which this definition would
otherwise apply do not announce or publicly confirm or inform the Trustee in writing at the
Company’s or the Trustee’s request that the reduction was the result, in whole or in part, of any
event or circumstance comprised of or arising as a result of, or in respect of, the applicable
Change of Control (whether or not the applicable Change of Control has occurred at the time of the
Rating Event).

     “S&P” means Standard & Poor’s Rating Services, a division of The McGraw-Hill Companies, Inc.

     “Voting Stock” means, with respect to any specified “person” (as that term is used in Section
13(d)(3) of the Exchange Act) as of any date, the capital stock of such person that is at the time
entitled to vote generally in the election of the board of directors
of such person.

     The Securities of this series are not entitled to the benefit of any sinking fund.

     The Indenture contains provisions for defeasance and discharge at any time of (i) the entire
indebtedness of this Security or (ii) 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 rights of the Holders of the
Securities of each series to be affected under the Indenture at any time by the Company 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. 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 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,
whether or not notation of such consent or waiver is made upon this Security.

     As provided in and subject to the provisions of the Indenture, the Holder of this Security
shall not have the right to institute any proceeding with respect to the Indenture or for the
appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall
have previously given the Trustee written notice of a continuing Event of Default with respect to
the Securities of this series, the Holders of not less than 25% in principal amount of the
Securities of this series at the time Outstanding shall have made written request to the Trustee to
institute proceedings in respect of such Event of Default as Trustee and offered the Trustee
reasonable indemnity, and the Trustee shall not have received from the Holders of a majority in
principal amount of the Securities of this series at the time Outstanding a direction inconsistent
with such request, and shall have failed to institute any such proceeding, for 60 days after
receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit
instituted by the Holder of this Security for the enforcement of any payment of principal hereof or
any premium or interest hereon on or after the respective due dates expressed herein.

6

 

     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 and rate, and in
the coin or currency, herein prescribed.

     As provided in the Indenture and subject to certain limitations therein set forth, the
transfer of this Security is registrable in the Security Register, upon surrender of this Security
for registration of transfer at the office or agency of the Company in any place where the
principal of and any premium and interest on this Security are payable, 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 his 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, shall 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 or an 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
Trustee and any agent of the Company 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 be
overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

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

proceedings and for which adequate reserves are presented in the Seller Financial Statements
included in the Seller Commission Documents.

     Section 3.16 Form S-3 Eligibility. Seller is eligible to use Form S-3 for the resale
registration statement contemplated by the Registration Rights Agreement.

ARTICLE IV.

REPRESENTATIONS AND WARRANTIES OF PURCHASERS

     Each Purchaser, severally and not jointly, represents and warrants to Seller with respect to
itself as follows:

     Section 4.1 Existence. Such Purchaser (a) is duly incorporated or formed, validly
existing and in good standing under the Laws of its respective jurisdiction of incorporation or
formation, and (b) has all requisite power and authority, and has all material governmental
licenses, authorizations, consents and approvals necessary to own its Properties and carry on its
business as its business is now being conducted, except where the failure to obtain such licenses,
authorizations, consents and approvals would not reasonably be expected to have a Purchaser
Material Adverse Effect. Each such Purchaser is not in default in the performance, observance or
fulfillment of any provision of its organizational documents, except where such default would not
have or would not reasonably be likely to have a Purchaser Material Adverse Effect.

     Section 4.2 No Conflicts. The execution, delivery and performance by such Purchaser
of the Basic Documents to which it is a party and all other agreements and instruments to be
executed and delivered by such Purchaser pursuant hereto or thereto or in connection herewith or
therewith, compliance by such Purchaser with the terms and provisions hereof and thereof, and the
purchase of the Purchased Units by such Purchaser do not and will not (a) violate any provision of
any Law, governmental permit, determination or award having applicability to such Purchaser or any
of its Properties, (b) conflict with or result in a violation of any provision of the
organizational documents of such Purchaser or (c) require any consent (other than standard internal
consents), approval or notice under or result in a violation or breach of or constitute (with or
without due notice or lapse of time or both) a default (or give rise to any right of termination,
cancellation or acceleration) under any note, bond, mortgage, license, loan or credit agreement or
other instrument or agreement to which such Purchaser is a party or by which such Purchaser or any
of its Properties may be bound, except in the case of clauses (a) and (c), where such conflict,
violation, default, breach, termination, cancellation, failure to receive consent, notice or
approval, or acceleration with respect to the

12

 

foregoing provisions of this Section 4.2 would not, individually or in the aggregate,
reasonably be expected to have a Purchaser Material Adverse Effect.

     Section 4.3 Authority. Such Purchaser has all necessary corporate, limited liability
company or partnership power and authority, as applicable, to execute, deliver and perform its
obligations under the Basic Documents to which it is a party and to consummate the transactions
contemplated thereby; the execution, delivery and performance by such Purchaser of the Basic
Documents to which such Purchaser is a party, and the consummation of the transactions contemplated
thereby, have been duly authorized by all necessary action on its part; and the Basic Documents to
which such Purchaser is a party will constitute the legal, valid and binding obligations of such
Purchaser, enforceable in accordance with their terms, except as such enforceability may be limited
by bankruptcy, insolvency, fraudulent transfer and similar Laws affecting creditors’ rights
generally or by general principles of equity, including principles of commercial reasonableness,
fair dealing and good faith.

     Section 4.4 No Side Agreements. Other than any existing confidentiality agreements in
favor of Seller that have been executed by such Purchaser or to which such Purchaser is otherwise
bound, there are no other agreements by, among or between such Purchaser or any of its Affiliates,
on the one hand, and Seller or any of its Affiliates, on the other hand, with respect to the
transactions contemplated hereby other than the Basic Documents to which Seller is a party;
provided, however, that, subject to such Purchaser’s compliance with its obligations under the U.S.
federal securities laws and its internal policies: (a) Purchaser, for purposes hereof, shall not be
deemed to include any employees, subsidiaries or Affiliates that are effectively walled off by
appropriate “Chinese Wall” information barriers approved by Purchaser’s legal or compliance
department (and thus have not been privy to any information concerning this transaction) (a “Walled
Off Person”) and (b) the foregoing representations in this paragraph shall not apply to any
transaction by or on behalf of Purchaser that was effected by a Walled Off Person in the ordinary
course of trading without the advice or participation of Purchaser or receipt of confidential or
other information regarding this transaction provided by Purchaser to such entity.

     Section 4.5 Investment. The Purchased Units are being acquired for such Purchaser’s
own account, the account of its Affiliates, or the accounts of clients for whom such Purchaser
exercises discretionary investment authority (all of whom such Purchaser hereby represents and
warrants are “accredited investors” within the meaning of Rule 501(a) of Regulation D or “qualified
institutional buyer” within the meaning of Rule 144A promulgated by the Commission pursuant to the
Securities Act), not as a nominee or agent, and with no present intention of distributing the
Purchased Units or any part thereof, and that such Purchaser has no present intention of selling or
granting any participation in or otherwise distributing the same in any transaction in violation of
the securities Laws of the United States of America or any state, without prejudice, however, to
such Purchaser’s right at all times to sell or otherwise dispose of all or any part of the
Purchased Units under a registration statement under the Securities Act and applicable state
securities Laws or under an exemption from such registration available thereunder (including,
without limitation, if available, Rule 144 promulgated thereunder).

13

 

If such Purchaser should in the future decide to dispose of any of the Purchased Units, such Purchaser
understands and agrees (a) that it may do so only (i) in compliance with the Securities Act and
applicable state securities law, as then in effect, or pursuant to an exemption therefrom
(including Rule 144 under the Securities Act) or (ii) in the manner contemplated by any
registration statement pursuant to which such securities are being offered, and (b) that
stop-transfer instructions to that effect will be in effect with respect to such securities.
Notwithstanding the foregoing, any Purchaser may at any time transfer Purchased Units to an
Affiliate of such Purchaser provided that any such transaction is exempt from registration under
the Securities Act and that such Affiliate agrees to be bound by the terms and conditions of this
Agreement.

     Section 4.6 Nature of Purchaser. Such Purchaser represents and warrants to, and
covenants and agrees with, Seller that, (a) it is an “accredited investor” within the meaning of
Rule 501 of Regulation D promulgated by the Commission pursuant to the Securities Act and (b) by
reason of its business and financial experience it has such knowledge, sophistication and
experience in making similar investments and in business and financial matters generally so as to
be capable of evaluating the merits and risks of the prospective investment in the Purchased Units,
is able to bear the economic risk of such investment and, at the present time, would be able to
afford a complete loss of such investment.

     Section 4.7 Receipt of Information. Such Purchaser acknowledges that it has (a) had
access to Seller’s periodic filings with the Commission and (b) been provided a reasonable
opportunity to ask questions of and receive answers from Representatives of Seller regarding such
matters.

     Section 4.8 Legend. It is understood that the certificates evidencing the Common
Units will bear the following legend: “These securities have not been registered under the
Securities Act of 1933, as amended (the “Securities Act”), or the securities laws of any state or
other jurisdiction. These securities may not be sold or offered for sale except pursuant to an
effective registration statement under the Securities Act or pursuant to an exemption from
registration thereunder, in each case in accordance with all applicable securities laws of the
states or other jurisdictions, and in the case of a transaction exempt from registration, such
securities may only be transferred if the transfer agent for such securities has received
documentation satisfactory to it that such transaction does not require registration under the
Securities Act.”

     Section 4.9 Certain Fees. No fees or commissions will be payable by such Purchaser to
brokers, finders, or investment bankers with respect to the sale of any of the Purchased Units or
the consummation of the transactions contemplated by this Agreement.

     Section 4.10 Restricted Securities. Such Purchaser understands that the Purchased
Units are characterized as “restricted securities” under the federal securities Laws inasmuch as
they are being acquired from Seller in a transaction not involving a public offering and that under
such Laws and applicable regulations such securities may be resold without registration under the
Securities Act only in certain limited

14

 

circumstances. In this connection, such Purchaser represents that it is knowledgeable with
respect to Rule 144 of the Commission promulgated under the Securities Act.

     Section 4.11 Short Selling. As of the execution of this Agreement, such Purchaser has
not engaged in any Short Sales involving Common Units owned by it between the time it first began
discussions with Seller about the transaction contemplated by this Agreement and the date of
execution of this Agreement; provided, however, that, subject to such Purchaser’s compliance with
its obligations under the U.S. federal securities laws and its internal policies: (a) Purchaser,
for purposes hereof, shall not be deemed to include any Walled Off Person and (b) the foregoing
representations in this paragraph shall not apply to any transaction by or on behalf of Purchaser
that was effected by a Walled Off Person in the ordinary course of trading without the advice or
participation of Purchaser or receipt of confidential or other information regarding this
transaction provided by Purchaser to such entity.

of the holders of a majority of the Purchased Units, Seller may not issue or sell any Common Units
or any securities convertible thereinto or exchangeable therefor prior to the Lock-Up Date.
Nothing contained above shall prevent (a) Seller from issuing (i) up to 1,800,000 Common Units or
(ii) equity securities, phantom units or similar issuances pursuant to the Equity Plan or any

18

 

offer for sale or solicit offers to buy any security (as defined in the Securities Act) that would be integrated
with the sale of the Purchased Units in a manner that would require the registration under the
Securities Act of the sale of the Purchased Units to the Purchasers.

     Section 6.2 Purchasers’ Lock-Ups. Without the prior written consent of Seller, each
Purchaser agrees that such Purchaser will not offer, sell, pledge or otherwise transfer or dispose
of any of its Purchased Units prior to the Lock-Up Date; provided, however, that any Purchaser may
transfer its Purchased Units to an Affiliate of such Purchaser or to any other Purchaser or an
Affiliate of such other Purchaser, provided that any such Affiliate transferee agrees to the terms
and conditions set forth in this Agreement, including but not limited to the restrictions set forth
in this Section 6.2.

     Section 6.3 Trading Activities. Such Purchaser’s trading activities, if any, with

commercially reasonable efforts promptly to take or cause to be taken all action and promptly to do
or cause to be done all things necessary, proper or advisable under applicable Law and regulations
to consummate and make effective the transactions contemplated by this Agreement. Without limiting
the foregoing, Seller and each Purchaser shall use its commercially reasonable efforts to make all
filings and obtain all consents of Governmental Authorities that may be necessary or, in the
reasonable opinion of the other Parties, as the case may be, advisable for the consummation of the
transactions contemplated by the Basic Documents.

     Section 6.5 Non-Disclosure; Interim Public Filings. Seller shall, on or before 8:30

INDEMNIFICATION

     Section 7.1 Indemnification by Seller. Seller agrees to indemnify each Purchaser and
its Affiliates and each of their respective Representatives (collectively, “Purchaser Related
Parties”), from, and hold each of them harmless against, any and all actions, suits,
proceedings (including any investigations, litigation or inquiries), demands, and causes of action,
and, in connection therewith, and promptly upon demand, pay or

19

 

reimburse each of them for all
reasonable costs, losses, liabilities, damages, or expenses
of any kind or nature whatsoever, including, without limitation, the reasonable fees and
disbursements of counsel and all other reasonable expenses incurred in connection with
investigating, defending or preparing to defend any such matter that may be incurred by them or
asserted against or involve any of them as a result of, arising out of, or in any way related to
the breach of any of the representations, warranties or covenants of Seller contained herein,
provided such claim for indemnification relating to a breach of a representation or warranty is
made prior to the expiration of such representation or warranty. Furthermore, Seller agrees that
it will indemnify and hold harmless each Purchaser and Purchaser Related Parties from and against
any and all claims, demands or liabilities for broker’s, finder’s, placement or other similar fees
or commissions incurred by Seller or alleged to have been incurred by Seller in connection with the
sale of any of the Purchased Units or the consummation of the transactions contemplated by this
Agreement.

     Section 7.2 Indemnification by Purchasers. Each Purchaser agrees, severally and not
jointly, to indemnify Seller and its Affiliates and each of their respective Representatives
(collectively, “Seller Related Parties”) from, and hold each of them harmless against any
and all actions, suits, proceedings (including any investigations, litigation, or inquiries),
demands, and causes of action, and, in connection therewith, and promptly upon demand, pay or
reimburse each of them for all reasonable costs, losses, liabilities, damages, or expenses of any
kind or nature whatsoever, including, without limitation, the reasonable fees and disbursements of
counsel and all other reasonable expenses incurred in connection with investigating, defending or
preparing to defend any such matter to the extent that it may be incurred by them or asserted
against or involve any of them as a result of, arising out of, or in any way related to the breach
of any of the representations, warranties or covenants of such Purchaser contained herein, provided
such claim for indemnification relating to a breach of the representations and warranties by such
Purchaser is made prior to the expiration of such representations and warranties. Furthermore,
each Purchaser agrees, severally and not jointly, that it will indemnify and hold harmless Seller
and Seller Related Parties from and against any and all claims, demands or liabilities for
broker’s, finder’s, placement or other similar fees or commissions incurred by such Purchaser or
alleged to have been incurred by such Purchaser in connection with the purchase of any of the
Purchased Units or the consummation of the transactions contemplated by this Agreement.

     Section 7.3 Indemnification Procedures. Promptly after any Seller Related Party or
Purchaser Related Party (hereinafter, the “Indemnified Party”) has received notice of any
indemnifiable claim hereunder, or the commencement of any Action or proceeding by a third person,
which the Indemnified Party believes in good faith is an indemnifiable claim under this Agreement,
the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”)
written notice of such claim or the commencement of such Action or proceeding, but failure to so
notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may
have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is
materially prejudiced by such failure. Such notice shall state the nature and the basis of such
claim to the extent then known. The Indemnifying Party shall have the right to

20

 

defend and settle,
at its own expense and by its own counsel who shall be reasonably
acceptable to the Indemnified Party, any such matter as long as the Indemnifying Party pursues
the same diligently and in good faith. If the Indemnifying Party undertakes to defend or settle,
it shall promptly notify the Indemnified Party of its intention to do so, and the Indemnified Party
shall cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects
in the defense thereof and the settlement thereof. Such cooperation shall include, but shall not
be limited to, furnishing the Indemnifying Party with any books, records and other information
reasonably requested by the Indemnifying Party and in the Indemnified Party’s possession or
control. Such cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party.
After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to
defend or settle any such asserted liability, and for so long as the Indemnifying Party diligently
pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses
incurred by the Indemnified Party in connection with any defense or settlement of such asserted
liability; provided, however, that the Indemnified Party shall be entitled (a) at its expense, to
participate in the defense of such asserted liability and the negotiations of the settlement
thereof and (b) if (i) the Indemnifying Party has failed to assume the defense and employ counsel
reasonably acceptable to the Indemnified Party or (ii) if the defendants in any such Action include
both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified Party shall
have concluded that there may be reasonable defenses available to the Indemnified Party that are
different from or in addition to those available to the Indemnifying Party or if the interests of
the Indemnified Party reasonably may be deemed to conflict with the interests of the Indemnifying
Party, then the Indemnified Party shall have the right to select a separate counsel and to assume
such legal defense and otherwise to participate in the defense of such Action, with the expenses
and fees of such separate counsel and other expenses related to such participation to be reimbursed
by the Indemnifying Party as incurred. Notwithstanding any other provision of this Agreement, the
Indemnifying Party shall not settle any indemnified claim without the consent of the Indemnified
Party, unless the settlement thereof imposes no liability or obligation on, and includes a complete
release from liability of, and does not contain any admission of wrongdoing or malfeasance by, the
Indemnified Party.

     Section 7.4 Survival. The Parties’ obligations under this Article VII shall only
become operative following the Closing Date and shall not survive any termination of this Agreement
pursuant to Section 8.15.

ARTICLE VIII.

MISCELLANEOUS

     Section 8.1 Interpretation of Provisions. Article, Section, Exhibit and Schedule
references are to this Agreement, unless otherwise specified. All references to instruments,
documents, contracts, and agreements are references to such instruments, documents, contracts, and
agreements as the same may be amended, supplemented, and otherwise modified from time to time,
unless otherwise specified. The word “including” shall mean “including but not limited to.”
Whenever a Party has an obligation under the Basic Documents, the expense of complying with that
obligation shall be an expense of

21

 

such Party unless otherwise specified. Whenever any
determination, consent, or approval
is to be made or given by a Party, such action shall be in such Party’s sole discretion unless
otherwise specified in this Agreement. If any provision in the Basic Documents is held to be
illegal, invalid, not binding, or unenforceable, such provision shall be fully severable and the
Basic Documents shall be construed and enforced as if such illegal, invalid, not binding, or
unenforceable provision had never comprised a part of the Basic Documents, and the remaining
provisions shall remain in full force and effect. The Basic Documents have been reviewed and
negotiated by sophisticated parties with access to legal counsel and shall not be construed against
the drafter.

     Section 8.2 Survival. The representations and warranties set forth in Section 3.2,
Section 3.5 Section 3.8, Section 3.9, Section 4.3, Section 4.4, Section 4.5, Section 4.6, Section
4.7, Section 4.8, Section 4.9, and Section 4.10 shall survive indefinitely, and the other
representations and warranties set forth herein shall survive for a period of twelve (12) months,
in each case, following the Closing Date regardless of any investigation made by or on behalf of
Seller or the Purchasers. The covenants made in this Agreement shall survive the Closing of the
transactions described herein and remain operative and in full force and effect regardless of
acceptance of any of the Purchased Units and payment therefor and repayment, conversion, exercise
or repurchase thereof.

     Section 8.3 No Waiver; Modifications in Writing.

     (a) Delay. No failure or delay on the part of any Party in exercising any
right, power or remedy hereunder shall operate as a waiver thereof, nor shall any single or
partial exercise of any such right, power or remedy preclude any other or further exercise
thereof or the exercise of any other right, power or remedy. The remedies provided for
herein are cumulative and are not exclusive of any remedies that may be available to a
Party at law or in equity or otherwise.

     (b) Specific Waiver. Except as otherwise provided herein, no amendment,
waiver, consent, modification or termination of any provision of this Agreement shall be
effective unless signed by each of the Parties hereto or thereto affected by such
amendment, waiver, consent, modification or termination. Any amendment, supplement or
modification of or to any provision of this Agreement, any waiver of any provision of this
Agreement, and any consent to any departure from the terms of any provision of this
Agreement shall be effective only in the specific instance and for the specific purpose for
which made or given. Except where notice is specifically required by this Agreement, no
notice to or demand on Seller in any case shall entitle Seller to any other or further
notice or demand in similar or other circumstances.

     Section 8.4 Binding Effect; Assignment.

     (a) Binding Effect. This Agreement shall be binding upon Seller, the
Purchasers and their respective successors and permitted assigns. Except as expressly
provided in this Agreement, this Agreement shall not be construed so as

22

 

to confer any right
or benefit upon any Person other than the Parties to this Agreement, and their respective
successors and permitted assigns.

     (b) Assignment of Rights. All or any portion of the rights and obligations of
each Purchaser under this Agreement may be transferred to any Affiliate of such Purchaser
but may not otherwise be transferred by such Purchaser without the prior written consent of
Seller (which consent shall not be unreasonably withheld by Seller), and in each case the
assignee shall be deemed to be bound by the provisions of this Agreement.

     Section 8.5 Confidentiality. Notwithstanding anything herein to the contrary, to the
extent that any Purchaser has executed or is otherwise bound by a confidentiality agreement in
favor of Seller, such Purchaser shall continue to be bound by such confidentiality agreement
(notwithstanding any termination provision contained therein). To the extent that any Purchaser
has not executed or is not otherwise bound by a confidentiality agreement in favor of Seller, and
has actually received Confidential Information from Seller, such Purchaser will refrain, and will
cause its Representatives to refrain, from disclosing to any other Person any Confidential
Information; provided, however, that with respect to any Purchaser who has not executed and is not
otherwise bound by a confidentiality agreement in favor of Seller, Seller acknowledges that Seller

     Section 8.7 Entire Agreement. This Agreement, the other Basic Documents and the other
agreements and documents referred to herein are intended by the Parties as a final expression of
their agreement and intended to be a complete and exclusive statement of the agreement and
understanding of the Parties hereto in respect of the subject matter contained herein. There are
no restrictions, promises, warranties or undertakings, other than those set forth or referred to
herein with respect to the rights granted by Seller or any of its Affiliates or Purchasers or any
of their Affiliates set forth herein. This Agreement supersedes all prior agreements and
understandings between the Parties with respect to such subject matter, including any term sheets
and commitment letters.

     Section 8.8 Governing Law. This Agreement will be construed in accordance with and
governed by the laws of the State of Texas without regard to principles of conflicts of laws.

     Section 8.9 Execution in Counterparts. This Agreement may be executed in any number
of counterparts and by different Parties hereto in separate counterparts, each of which
counterparts, when so executed and delivered, shall be deemed to be an original and all of which
counterparts, taken together, shall constitute but one and the same Agreement.

     Section 8.10 Costs and Expenses. Each Party shall be responsible for such Party’s own
expenses in connection with this Agreement and the transactions contemplated hereby, except that
Seller will pay Baker Botts up to $75,000 for legal fees incurred by Baker Botts as counsel to
certain Purchasers and for its role in facilitating the process. Any fees in excess of $75,000
shall be paid pro rata by all Purchasers in proportion to the aggregate number of Purchased Units
set forth opposite the names of such Purchasers on Schedule 2.1.

24

 

     Section 8.11 Short Selling Acknowledgement and Agreement. Each Purchaser understands
and acknowledges, severally and not jointly with any other Purchaser, that the Commission currently
takes the position that coverage of Short Sales of securities “against the box” prior to the
effective date of a registration statement is a violation of
Section 5 of the Securities Act. Each Purchaser agrees, severally and not jointly, that it
will not engage in any Short Sales that result in the disposition of the Common Units underlying
the Class C Units acquired hereunder by such Purchaser until such time as the Resale Registration
Statement (as defined in the Registration Rights Agreement) is declared or deemed effective by the
Commission or such Common Units are no longer subject to any restrictions on resale.

     Section 8.12 Distributions. If the Closing Date is after the record date relating to
a distribution to be made to holders of Common Units with respect to the fiscal quarter ended March
31, 2011 or any other distribution to be made to holders of Common Units, then the Purchasers shall
not be entitled to receive such distribution but the Class C Unit Price payable by Purchasers shall
be reduced by an amount equal to such per unit distribution and the number of Purchased Units set
forth on Schedule 2.1 shall be increased accordingly.

     Section 8.13 Removal of Legend. In connection with a sale of the Purchased Units by a
Purchaser in reliance on Rule 144, the applicable Purchaser or its broker shall deliver to Seller a
broker representation letter providing any information Seller deems necessary to determine that the
sale of the Purchased Units is made in compliance with Rule 144, including, as may be appropriate,
a certification that such Purchaser is not an affiliate of Seller and regarding the length of time
the Purchased Units have been held. Upon receipt of such representation letter, Seller shall as
soon as reasonably practicable exchange unit certificates bearing the legend described in Section
4.8 for unit certificates without such legend. After any Purchaser or its permitted assigns have
held the Purchased Units for one year, if such Purchased Units still bear the legend described in
Section 4.8, such Purchaser may request Seller to remove the legend and Seller agrees to take all
steps necessary to effect the removal of the legend as soon as reasonably practicable. Seller shall
bear all direct costs and expenses associated with the removal of a legend pursuant to this Section
8.13 (including without limitation reasonable fees of legal counsel in connection with any legal
opinion letters required to be issued in connection with such removal), regardless of whether the
request is made in connection with a sale or otherwise, so long as such Purchaser or its permitted
assigns provide to Seller any information Seller deems necessary to determine that the legend is no
longer required under the Securities Act or applicable state laws, including a certification that
the holder is not an affiliate of Seller and regarding the length of time the Purchased Units have
been held; provided, however, Seller shall not be responsible for any legal fees and expenses of
counsel incurred by such Purchaser in connection therewith.

     Section 8.14 Adjustment of the Class C Units. The provisions of this Agreement shall
apply to the full extent set forth herein with respect to any and all equity interests of Seller or
any successor or assign of Seller (whether by merger, consolidation, sale of assets or otherwise)
which may be issued in respect of, in exchange for or in substitution of, the Class C Units, and
shall be appropriately adjusted for combinations,

25

 

recapitalizations and the like occurring after
the date of this Agreement and prior to the Closing.

     Section 8.15 Termination.

     (a) Notwithstanding anything herein to the contrary, this Agreement may be terminated
at any time at or prior to the Closing by the written consent of a majority in interest of
the Purchasers, upon a breach in any material respect by Seller of any covenant or
agreement set forth in this Agreement.

     (b) Notwithstanding anything herein to the contrary, in the event that any condition
to Seller’s obligation to close specified in Sections 5.1(a) or 5.1(c) is not satisfied or
waived on the Closing Date, Seller may terminate this Agreement upon written notice to the
Purchasers.

     (c) Notwithstanding anything herein to the contrary, this Agreement shall
automatically terminate at any time at or prior to the Closing:

     (i) if a Law shall have been enacted or promulgated, or if any action shall
have been taken by any Governmental Authority of competent jurisdiction that
permanently restrains, permanently precludes, permanently enjoins or otherwise
permanently prohibits the consummation of the transactions contemplated by this
Agreement or the Major Acquisition Agreement or makes the transactions contemplated
by this Agreement illegal;

     (ii) upon the termination of the Major Acquisition Agreement; or

     (iii) if the Closing shall not have occurred by the date that is ninety (90)
days from the date hereof.

     (d) In the event of the termination of this Agreement as provided in this Section 8.15
(1) this Agreement shall forthwith become null and void, (2) within two (2) Business Days
following such termination, Seller shall pay the Commitment Fee to each Purchaser in
immediately available funds by wire transfer, and (3) there shall be no liability on the
part of any Party hereto, except as set forth in Section 8.10 and except with respect to
the requirement to comply with any confidentiality agreement in favor of Seller; provided
that nothing herein shall relieve any Party from any liability or obligation with respect
to any willful breach of this Agreement.

REGISTRATION RIGHTS

     Section 2.1 Registration.

          (a) Request for Filing and Deadline To Become Effective. As soon as practicable
following the receipt of a request from any Holder to register its Registrable Securities, the
Partnership shall notify all Holders that a Resale Registration Statement will be filed within 30
days from the date such request is made. Within five (5) Business Days of receipt of the notice of
the filing, such Holders shall notify the Partnership whether they wish to have their Registrable
Securities included in the Resale Registration Statement. If a Holder does not respond within such
time period, it will be deemed to have chosen not to have its Registrable Securities included. The
Partnership shall prepare and file a Resale Registration Statement under the Securities Act with
respect to all of the Registrable Securities of the Holders that have requested inclusion thereon.
The Resale Registration Statement filed pursuant to this Section 2.1(a) shall be on such
appropriate registration form of the Commission as shall be selected by the Partnership. The
Partnership shall use its commercially reasonable efforts to cause the Resale Registration
Statement to become effective no later than 90 days following the date it is initially filed (the
“Target Effective Date”). The Partnership will use its commercially reasonable efforts to
cause the Resale Registration Statement filed pursuant to this Section 2.1 to be continuously
effective under the Securities Act until all Registrable Securities covered by the Resale
Registration Statement have ceased to be Registrable Securities (the “Effectiveness
Period”). The Resale Registration Statement when declared effective (including the documents
incorporated therein by reference) will comply as to form in all material respects with all
applicable requirements of the Securities Act and the Exchange Act and will not contain an untrue
statement of a material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein not misleading (and, in the case of any prospectus
contained in such Resale Registration Statement, in the light of the circumstances under which a
statement is made). As soon as practicable following the date that the Resale Registration
Statement becomes effective, but in any event within five Business Days of such date, the

Partnership shall provide the Holders with written notice of the effectiveness of the Resale
Registration Statement. Any Holder may deliver advance written notice (a “Resale Opt-Out
Notice”) to the Partnership requesting that such Holder not receive notice of any request to
file a Resale Registration Statement; provided, however, that such Holder may later revoke any such
Resale Opt-Out Notice in writing. Following receipt of a Resale Opt-Out Notice from a Holder
(unless subsequently revoked), the Partnership shall not be required to deliver any notice to such
Holder pursuant to this Section 2.1 and such Holder shall no longer be entitled to be included in
any Resale Registration Statement filed by the Partnership pursuant to this Section 2.1. The
Holders indicated on Schedule 1 hereto shall each be deemed to have delivered a Resale Opt-Out
Notice as of the date hereof.

          (b) Failure To Become Effective. If the Resale Registration Statement required by
Section 2.1(a) does not become or is not declared effective on or before the Target Effective Date,
then the Partnership shall pay each Holder (with respect to either the Purchased Units or the
Converted Class C Units, as applicable, of each such Holder which are included on such Resale
Registration Statement), as liquidated damages and not as a penalty, (i) for each non-overlapping
30-day period for the first 60 days following the Target Effective Date, an amount equal to (A)
0.25% times (B) the product of (x) the Class C Unit Price times (y) the number of Purchased Units
or the Converted Class C Units, as applicable, then held by such Holder and included on such Resale
Registration Statement and which may not otherwise be disposed of pursuant to Rule 144 without any
restriction, including if the Holder is an Affiliate of the Partnership, restrictions that apply to
sales by Affiliates (such product of (x) and (y) being the “Liquidated Damages
Multiplier”), and (ii) for each non-overlapping 30-day period beginning on the 61st day
following the Target Effective Date, with such payment amount increasing by an additional amount
equal to 0.25% times the Liquidated Damages Multiplier per non-overlapping 30-day period for each
subsequent 60 days (i.e., 0.5% for 61-120 days, 0.75% for 121-180 days, and 1.0% thereafter) up to
a maximum amount equal to 1.0% times the Liquidated Damages Multiplier per non-overlapping 30-day
period (the “Liquidated Damages”); provided, that the aggregate amount of Liquidated
Damages payable by the Partnership per Purchased Unit or Converted Class C Unit, as applicable, may
not exceed 5.0% of the Class C Unit Price. The Liquidated Damages payable pursuant to the
immediately preceding sentence shall be payable within ten Business Days after the end of each such
non-overlapping 30-day period. Any Liquidated Damages shall be paid to each Holder in cash;
provided, however, if the Partnership certifies that it is unable to pay Liquidated Damages in cash
because such payment will violate a covenant in an existing credit agreement or other indebtedness,
then the Partnership may, in its sole discretion, pay the Liquidated Damages in kind in the form of
the issuance of Class C Units, unless otherwise not permitted. Upon any issuance of Class C Units
as Liquidated Damages, the Partnership shall promptly prepare and file a supplemental listing
application with the NYSE to list such Converted Class C Units. The determination of the number of
Class C Units to be paid as Liquidated Damages shall be based on the volume-weighted average price
of the Common Units for the ten trading days immediately preceding the date on which the Liquidated
Damages payment is due, less a discount of 2%. The payment of Liquidated Damages under this
Section 2.1(b) and Section 2.1(e) to a Holder shall cease at such time as the Resale Registration
Statement becomes or is declared effective by the Commission or at such time as the securities
included on the Resale Registration Statement are no longer Registrable Securities or may be
disposed of pursuant to Rule 144 without any restriction (including, if the Holder is an Affiliate

5

 

of the Partnership, restrictions that apply to sales by Affiliates), and shall be prorated for
any period of less than 30 days in which the Liquidated Damages cease.

          (c) Waiver of Liquidated Damages. If the Partnership is unable to cause a Resale
Registration Statement to become effective by the Target Effective Date as a result of an
acquisition, merger, reorganization, disposition or other similar transaction, then the Partnership
may request a waiver of the Liquidated Damages, which may be granted by the consent of the Holders
of a majority of the outstanding Registrable Securities that have been included on such Resale
Registration Statement, in their sole discretion, and which such waiver shall apply to all the
Holders of Registrable Securities included on such Resale Registration Statement.

          (d) Delay Rights. Notwithstanding anything to the contrary contained herein, the
Partnership may, upon written notice to any Selling Holder whose Registrable Securities are
included in the Resale Registration Statement, suspend such Selling Holder’s use of any prospectus
which is a part of the Resale Registration Statement (in which event the Selling Holder shall
discontinue sales of the Registrable Securities pursuant to the Resale Registration Statement but
may settle any previously made sales of Registrable Securities) if (i) the Partnership is pursuing
an acquisition, merger, reorganization, disposition or other similar transaction and the
Partnership determines in good faith that the Partnership’s ability to pursue or consummate such a
transaction would be materially adversely affected by any required disclosure of such transaction
in the Resale Registration Statement or (ii) the Partnership has experienced some other material
non-public event the disclosure of which at such time, in the good faith judgment of the
Partnership, would materially adversely affect the Partnership; provided, however, in no event
shall the Selling Holders be suspended from selling Registrable Securities pursuant to the Resale
Registration Statement for a period that exceeds an aggregate of 60 days in any 180-day period or
105 days in any 365-day period, in each case, exclusive of days covered by any lock-up agreement
executed by a Selling Holder in connection with any Underwritten Offering. Upon disclosure of such
information or the termination of the condition described above, the Partnership shall provide
prompt notice to the Selling Holders whose Registrable Securities are included in the Resale
Registration Statement, and shall promptly terminate any suspension of sales it has put into effect
and shall take such other reasonable actions to permit registered sales of Registrable Securities
as contemplated in this Agreement.

          (e) Additional Rights to Liquidated Damages. If (i) the Holders shall be prohibited
from selling their Registrable Securities under the Resale Registration Statement as a result of a
suspension pursuant to Section 2.1(d) of this Agreement in excess of the periods permitted therein
or (ii) the Resale Registration Statement is filed and declared effective but, during the
Effectiveness Period, shall thereafter cease to be effective or fail to be usable for its intended
purpose without being succeeded within 60 days by a post-effective amendment pursuant thereto, a
supplement to the prospectus or a report filed with the Commission pursuant to Section 13(a),
13(c), 14 or 15(d) of the Exchange Act, then until the suspension is lifted or a post-effective
amendment, supplement or report is filed with the Commission and declared effective, but not
including any day on which a suspension is lifted or such amendment, supplement or report is
declared effective, if applicable, the Partnership shall owe the Holder an amount equal to the
Liquidated Damages, following the earlier of (i) the date on which the suspension period exceeded
the permitted period or (ii) the 61st day after the Resale Registration Statement ceased
to be effective or failed to be useable for its intended purposes. All of the

6

 

provisions in Section 2.1(b) with respect to the payment of the Liquidated Damages, including
but not limited to the ability to issue additional Class C Units in lieu of cash payments, the time
period in which payments are due, and the determination of the number of Class C Units to issue as
Liquidated Damages shall be applicable to the Liquidated Damages payable hereunder. For purposes
of this Section 2.1(e), a suspension shall be deemed lifted on the date that notice that the
suspension has been lifted is delivered to the Holders pursuant to Section 3.1 of this Agreement.

          (f) Termination of Rights. Other than as set forth otherwise in this Agreement, a
Holder’s rights (and any transferee’s rights pursuant to Section 2.10) under this Section 2.1,
including rights to Liquidated Damages (other than Liquidated Damages owing but not yet paid),
shall terminate upon the termination of the Effectiveness Period.

          (g) No Demand Rights. Notwithstanding any other provision of this Agreement, no
Holder of Registrable Securities shall be entitled to any “demand” rights or similar rights that
would require the Partnership to effect an Underwritten Offering solely on behalf of such Holder.

     Section 2.2 Piggyback Rights.

          (a) Underwritten Offering Piggyback Rights. Following such time as the Class C Units
have been converted into Common Units and if such Common Units are still Registrable Securities, if
the Partnership proposes to file (i) a registration statement and such Holder has not previously
included its Registrable Securities in a Resale Registration Statement contemplated by Section
2.1(a) of this Agreement that is currently effective, or (ii) a prospectus supplement to an
effective registration statement, so long as the Corporation is a WKSI at such time or, whether or
not the Corporation is a WKSI, so long as the Registrable Securities were previously included in
the underlying shelf Registration Statement or are included on an effective Resale Registration
Statement, or in any case in which Holders may participate in such offering without the filing of a
post-effective amendment, in each case, for the sale of Common Units in an Underwritten Offering
for its own account and/or another Person, other than (a) a registration relating solely to
employee benefit plans, (b) a registration relating solely to a Rule 145 transaction, or (c) a
registration on any registration form which does not permit secondary sales, then as soon as
practicable following the engagement of counsel by the Partnership to prepare the documents to be
used in connection with an Underwritten Offering, the Partnership shall give notice (including, but
not limited to, notification by electronic mail) of such proposed Underwritten Offering to each
Holder owning more than $10.0 million of such Common Units, calculated on the basis of the Class C
Unit Price, and such notice shall offer such Holder the opportunity to participate in any
Underwritten Offering and to include in such Underwritten Offering such number of Registrable
Securities that are Common Units (the “Included Registrable Securities”) as each such
Holder may request in writing, subject to any registration rights existing prior to the Closing
Date and customary underwriter cutbacks; provided, however, that the Partnership shall not be
required to provide such opportunity (i) to any such Holder that does not offer a minimum of $10.0
million of Registrable Securities (based on the Class C Unit Price), or (ii) to such Holders if the
Partnership has been advised by the Managing Underwriter that the inclusion of Registrable
Securities for sale for the benefit of the Holders will have an adverse effect on the price, timing
or distribution of the Common Units in the Underwritten Offering, then the amount of Registrable
Securities to be offered for the accounts of Holders shall be determined based on

7

 

the provisions of Section 2.2(b). Any notice required to be provided in this Section 2.2(a)
to Holders shall be provided on a Business Day pursuant to Section 3.1 hereof and receipt of such
notice shall be confirmed by the Holder. The Holder will have two Business Days (or one Business
Day in connection with any overnight or bought Underwritten Offering) after notice has been
delivered to request in writing the inclusion of Registrable Securities that are Common Units in
the Underwritten Offering. If no written request for inclusion from a Holder is received within
the specified time, each such Holder shall have no further right to participate in such
Underwritten Offering. If, at any time after giving written notice of its intention to undertake
an Underwritten Offering and prior to the closing of such Underwritten Offering, the Partnership
shall determine for any reason not to undertake or to delay such Underwritten Offering, the
Partnership may, at its election, give written notice of such determination to the Selling Holders
and, (x) in the case of a determination not to undertake such Underwritten Offering, shall be
relieved of its obligation to sell any Included Registrable Securities in connection with such
terminated Underwritten Offering, and (y) in the case of a determination to delay such Underwritten
Offering, shall be permitted to delay offering any Included Registrable Securities for the same
period as the delay in the Underwritten Offering. Any Selling Holder shall have the right to
withdraw such Selling Holder’s request for inclusion of such Selling Holder’s Registrable
Securities in such Underwritten Offering by giving written notice to the Partnership of such
withdrawal at or prior to the time of pricing of such Underwritten Offering. Any Holder may
deliver written notice (an “Piggyback Opt-Out Notice”) to the Partnership requesting that
such Holder not receive notice from the Partnership of any proposed Underwritten Offering;
provided, however, that such Holder may later revoke any such Piggyback Opt-Out Notice in writing.
Following receipt of an Piggyback Opt-Out Notice from a Holder (unless subsequently revoked), the
Partnership shall not be required to deliver any notice to such Holder pursuant to this Section
2.2(a) and such Holder shall no longer be entitled to participate in Underwritten Offerings by the
Partnership pursuant to this Section 2.2(a). The Holders indicated on Schedule 1 hereto shall each
be deemed to have delivered an Piggyback Opt-Out Notice as of the date hereof.

          (b) Priority of Piggyback Rights. If the Managing Underwriter or Underwriters of any
proposed Underwritten Offering advises the Partnership that the total amount of Registrable
Securities that the Selling Holders and any other Persons intend to include in such offering
exceeds the number that can be sold in such offering without being likely to have an adverse effect
on the price, timing or distribution of the Common Units offered or the market for the Common
Units, then the Common Units to be included in such Underwritten Offering shall include the number
of Registrable Securities that are Common Units that such Managing Underwriter or Underwriters
advises the Partnership can be sold without having such adverse effect, with such number to be
allocated (i) first, to the Partnership and, (ii) second, pro rata among the Selling Holders who
have requested participation in such Underwritten Offering and any other holder of securities of
the Partnership having rights of registration that are neither expressly senior nor subordinated to
the Registrable Securities (the “Parity Securities”). The pro rata allocations for each
Selling Holder who has requested participation in such Underwritten Offering shall be the product
of (A) the aggregate number of Registrable Securities that are Common Units proposed to be sold in
such Underwritten Offering multiplied by (B) the fraction derived by dividing (x) the number of
Registrable Securities that are Common Units owned on the Closing Date by such Selling Holder by
(y) the aggregate number of Registrable Securities that are Common Units owned on the Closing Date
by all Selling Holders plus the aggregate

8

 

number of Parity Securities owned on the Closing Date by all holders of Parity Securities that
are participating in the Underwritten Offering.

          (c) Termination of Piggyback Registration Rights. The piggyback rights under Section
2.2 will terminate at the earlier of (i) the time at which a Holder and its Affiliates own less
than $10.0 million of Common Units issued upon conversion of the Class C Units (based on the Class
C Unit Price) or (ii) the Common Units into which the Class C Units are convertible cease to be
Registrable Securities. When a Holder, together with any of its Affiliates who are also Holders,
owns less than $10.0 million of Registrable Securities that are Common Units (based on the Class C
Unit Price), it must notify the Partnership.

     Section 2.3 Underwritten Offering. General Procedures. In connection with
any Underwritten Offering under this Agreement, the Partnership shall be entitled to select the
Managing Underwriter or Underwriters in its sole discretion. In connection with an Underwritten
Offering contemplated by this Agreement in which a Selling Holder participates, each Selling Holder
and the Partnership shall be obligated to enter into an underwriting agreement with the Managing
Underwriter or Underwriters which contains such representations, covenants, indemnities and other
rights and obligations as are customary in underwriting agreements for firm commitment offerings of
equity securities. No Selling Holder may participate in an Underwritten Offering unless such
Selling Holder agrees to sell its Registrable Securities on the basis provided in such underwriting
agreement and completes and executes all questionnaires, powers of attorney, indemnities and other
documents reasonably required under the terms of such underwriting agreement. Each Selling Holder
may, at its option, require that any or all of the representations and warranties by, and the other
agreements on the part of, the Partnership to and for the benefit of such underwriters also be made
to and for such Selling Holder’s benefit and that any or all of the conditions precedent to the
obligations of such underwriters under such underwriting agreement also be conditions precedent to
its obligations. No Selling Holder shall be required to make any representations or warranties to
or agreements with the Partnership or the underwriters other than representations, warranties or
agreements regarding such Selling Holder, its authority to enter into such underwriting agreement
and to sell, and its ownership of the securities being registered on its behalf and its intended
method of distribution and any other representation required by law. If any Selling Holder
disapproves of the terms of an Underwritten Offering, such Selling Holder may elect to withdraw
therefrom by notice to the Partnership and the Managing Underwriter; provided, however, that such
withdrawal must be made at least one Business Day prior to the time of pricing of such Underwritten
Offering to be effective. No such withdrawal or abandonment shall affect the Partnership’s
obligation to pay Registration Expenses.

     Section 2.4 Sale Procedures. In connection with its obligations under this Article
II, the Partnership will, as expeditiously as possible:

          (a) prepare and file with the Commission such amendments and supplements to the Resale
Registration Statement and the prospectus used in connection therewith as may be necessary to keep
the Resale Registration Statement effective for the Effectiveness Period and as may be necessary to
comply with the provisions of the Securities Act with respect to the disposition of all Registrable
Securities covered by the Resale Registration Statement;

9

 

          (b) furnish to each Selling Holder (i) as far in advance as reasonably practicable before
filing the Resale Registration Statement or any supplement or amendment thereto, upon request,
copies of reasonably complete drafts of all such documents proposed to be filed (including exhibits
and each document incorporated by reference therein to the extent then required by the rules and
regulations of the Commission), and provide each such Selling Holder the opportunity to object to
any information pertaining to such Selling Holder and its plan of distribution that is contained
therein and make the corrections reasonably requested by such Selling Holder with respect to such
information prior to filing the Resale Registration Statement or supplement or amendment thereto,
and (ii) such number of copies of the Resale Registration Statement and the prospectus included
therein and any supplements and amendments thereto as such Selling Holder may reasonably request in
order to facilitate the public sale or other disposition of the Registrable Securities covered by
such Resale Registration Statement;

          (c) if applicable, use its commercially reasonable efforts to register or qualify the
Registrable Securities covered by the Resale Registration Statement under the securities or blue
sky laws of such jurisdictions as the Selling Holders shall reasonably request; provided, however,
that the Partnership will not be required to qualify generally to transact business in any
jurisdiction where it is not then required to so qualify or to take any action which would subject
it to general service of process in any such jurisdiction where it is not then so subject;

          (d) promptly notify each Selling Holder, at any time when a prospectus relating thereto is
required to be delivered by any of them under the Securities Act, of (i) the filing of the Resale
Registration Statement or any prospectus or prospectus supplement to be used in connection
therewith, or any amendment or supplement thereto, and, with respect to such Resale Registration
Statement or any post-effective amendment thereto, when the same has become effective; and (ii) the
receipt of any written comments from the Commission with respect to any filing referred to in
clause (i) and any written request by the Commission for amendments or supplements to the Resale
Registration Statement or any prospectus or prospectus supplement thereto;

          (e) immediately notify each Selling Holder, at any time when a prospectus relating thereto is
required to be delivered under the Securities Act, of (i) the happening of any event as a result of
which the prospectus or prospectus supplement contained in the Resale Registration Statement, as
then in effect, includes an untrue statement of a material fact or omits to state any material fact
required to be stated therein or necessary to make the statements therein not misleading (in the
case of any prospectus contained therein, in the light of the circumstances under which a statement
is made); (ii) the issuance or express threat of issuance by the Commission of any stop order
suspending the effectiveness of the Resale Registration Statement, or the initiation of any
proceedings for that purpose; or (iii) the receipt by the Partnership of any notification with
respect to the suspension of the qualification of any Registrable Securities for sale under the
applicable securities or blue sky laws of any jurisdiction. Following the provision of such
notice, the Partnership agrees to as promptly as practicable amend or supplement the prospectus or
prospectus supplement or take other appropriate action so that the prospectus or prospectus
supplement does not include an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein not misleading in the
light of the circumstances then existing and to take such other commercially

10

 

reasonable action as is necessary to remove a stop order, suspension, threat thereof or
proceedings related thereto;

          (f) upon request and subject to appropriate confidentiality obligations, furnish to each
Selling Holder copies of any and all transmittal letters or other correspondence with the
Commission or any other governmental agency or self-regulatory body or other body having
jurisdiction (including any domestic or foreign securities exchange) relating to such offering of
Registrable Securities;

          (g) otherwise use its commercially reasonable efforts to comply with all applicable rules and
regulations of the Commission, and make available to its security holders, as soon as reasonably
practicable, an earnings statement, which earnings statement shall satisfy the provisions of
Section 11(a) of the Securities Act and Rule 158 promulgated thereunder;

          (h) cause all such Registrable Securities registered pursuant to this Agreement to be listed
on each securities exchange or nationally recognized quotation system on which similar securities
issued by the Partnership are then listed;

          (i) use its commercially reasonable efforts to cause the Registrable Securities to be
registered with or approved by such other governmental agencies or authorities as may be necessary
by virtue of the business and operations of the Partnership to enable the Selling Holders to
consummate the disposition of such Registrable Securities;

          (j) provide a transfer agent and registrar for all Registrable Securities covered by such
registration statement not later than the effective date of such registration statement;

          (k) if requested by a Selling Holder, (i) incorporate in a prospectus supplement or
post-effective amendment such information as such Selling Holder reasonably requests to be included
therein relating to the sale and distribution of Registrable Securities, including information with
respect to the number of Registrable Securities being offered or sold, the purchase price being
paid therefor and any other terms of the offering of the Registrable Securities to be sold in such
offering; and (ii) make all required filings of such prospectus supplement or post-effective
amendment after being notified of the matters to be incorporated in such prospectus supplement or
post-effective amendment; and

          (l) The Partnership agrees that, if any Holder could reasonably be deemed to be an
“underwriter,” as defined in Section 2(a)(11) of the Securities Act, in connection with the Resale
Registration Statement and any amendment or supplement thereof, then the Partnership will
reasonably cooperate with such Holder in allowing such Holder to conduct customary “underwriter’s
due diligence” with respect to the Partnership and satisfy its obligations in respect thereof. In
addition, at any Holder’s request, the Partnership will furnish to such Holder, on the date of the
effectiveness of the Resale Registration Statement and thereafter from time to time on such dates
as such Holder may reasonably request, (i) a “cold comfort” letter, dated such date, from the
Partnership’s independent certified public accountants in form and substance as is customarily
given by independent certified public accountants to underwriters in an underwritten public
offering, addressed to such Holder, (ii) an opinion, dated as of such date, of counsel representing
the Partnership for purposes of the Resale Registration Statement, in form, scope

11

 

and substance as is customarily given in an underwritten public offering, including a standard
“10b-5” opinion for such offering, addressed to such Holder and (iii) a standard officer’s
certificate from the chief executive officer or chief financial officer, or other officers serving
such functions, of the General Partner addressed to the Holder; provided, however, that with
respect to any placement agent, the Partnership’s obligations with respect to Section 2.4) shall be
limited to one time, with an additional bring-down request within 30 days of the date of such
documents. Each Selling Holder, upon receipt of notice from the Partnership of the happening of
any event of the kind described in subsection (e) of Section 2.4, shall forthwith discontinue
offers and sales of the Registrable Securities until such Selling Holder’s receipt of the copies of
the supplemented or amended prospectus contemplated by subsection (e) of Section 2.4 or until it is
advised in writing by the Partnership that the use of the prospectus may be resumed and has
received copies of any additional or supplemental filings incorporated by reference in the
prospectus, and, if so directed by the Partnership, such Selling Holder will, or will request the
managing underwriter or underwriters, if any, to deliver to the Partnership (at the Partnership’s
expense) all copies in their possession or control, other than permanent file copies then in such
Selling Holder’s possession, of the prospectus covering such Registrable Securities current at the
time of receipt of such notice.

     Section 2.5 Cooperation by Holders. The Partnership shall have no obligation to
include Registrable Securities of a Holder in the Resale Registration Statement who has failed to
timely furnish such information that the Partnership determines, after consultation with its
counsel, is reasonably required in order for the registration statement or prospectus supplement,
as applicable, to comply with the Securities Act, including the execution of the initial Selling
Unitholder Notice and Questionnaire attached at Exhibit A to this Agreement by the date specified
thereon.

     Section 2.6 Restrictions on Public Sale by Holders of Registrable Securities. For so
long as the Purchased Units are Registrable Securities, each Holder agrees that it will not sell
any Class C Units, Common Units or other equity securities of the Partnership for a period of up to
60 days following the pricing date of an Underwritten Offering of equity securities by the
Partnership; provided, however, that the duration of the foregoing restrictions shall be no longer
than the duration of the shortest restriction imposed by the underwriters on the officers,
directors or any Affiliate of the Partnership. In addition, the provisions of this Section 2.6
shall not apply with respect to a Holder that (i) owns less than $10.0 million of Registrable
Securities based on the Class C Unit Price, or (ii) has delivered a Piggyback Opt-Out Notice or a
Resale Opt-Out Notice to the Partnership pursuant to Section 2.2 hereof.

     Section 2.7 Expenses.

          (a) Expenses. The Partnership will pay all reasonable Registration Expenses as
determined in good faith. Each Selling Holder shall pay its pro rata share of all Selling Expenses
in connection with any sale of its Registrable Securities hereunder. In addition, except as
otherwise provided in Section 2.8 hereof, the Partnership shall not be responsible for legal fees
incurred by Holders in connection with the exercise of such Holders’ rights hereunder.

          (b) Certain Definitions. “Registration Expenses” means all expenses incident
to the Partnership’s performance under or compliance with this Agreement to effect the registration

12

 

of Registrable Securities on the Resale Registration Statement pursuant to Section 2.1 and the
disposition of such Registrable Securities, including, without limitation, all registration,
filing, securities exchange listing and NYSE fees, all registration, filing, qualification and
other fees and expenses of complying with securities or blue sky laws, fees of the Financial
Industry Regulatory Authority, fees of transfer agents and registrars, all word processing,
duplicating and printing expenses, any transfer taxes and the fees and disbursements of counsel and
independent public accountants for the Partnership, including the expenses of any special audits or
“cold comfort” letters required by or incident to such performance and compliance. “Selling
Expenses” means all underwriting fees, discounts and selling commissions or similar fees or
arrangements allocable to the sale of the Registrable Securities.

     Section 2.8 Indemnification.

          (a) By the Partnership. In the event of a registration of any Registrable Securities
under the Securities Act pursuant to this Agreement, the Partnership will indemnify and hold
harmless each Selling Holder thereunder, its directors, officers, employees and agents and each
Person, if any, who controls such Selling Holder and its directors, officers, employees or agents
(collectively, the “Selling Holder Indemnified Persons”), against any losses, claims,
damages, expenses or liabilities (including reasonable attorneys’ fees and expenses) (collectively,
“Losses”), joint or several, to which such Selling Holder Indemnified Person may become
subject under the Securities Act, the Exchange Act or otherwise, insofar as such Losses (or actions
or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon
any untrue statement or alleged untrue statement of any material fact (in the case of any
prospectus, in light of the circumstances under which such statement is made) contained in the
Resale Registration Statement, any preliminary prospectus, prospectus supplement, free writing
prospectus or final prospectus contained therein, or any amendment or supplement thereof, or arise
out of or are based upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein (in the case of a prospectus, in
light of the circumstances under which they were made) not misleading, and will reimburse each such
Selling Holder Indemnified Person for any legal or other expenses reasonably incurred by them in
connection with investigating or defending any such Loss or actions or proceedings; provided,
however, that the Partnership will not be liable in any such case if and to the extent that any
such Loss arises out of or is based upon an untrue statement or alleged untrue statement or
omission or alleged omission so made in conformity with information furnished by such Selling
Holder Indemnified Person in writing specifically for use in the Resale Registration Statement, or
prospectus supplement, as applicable. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of such Selling Holder Indemnified Person, and
shall survive the transfer of such securities by such Selling Holder.

          (b) By Each Selling Holder. Each Selling Holder agrees severally and not jointly to
indemnify and hold harmless the Partnership, the General Partner and each of their respective
directors, officers, employees and agents and each Person, if any, who controls the Partnership
within the meaning of the Securities Act or of the Exchange Act, and its directors, officers,
employees and agents, to the same extent as the foregoing indemnity from the Partnership to the
Selling Holders, but only with respect to information regarding such Selling Holder furnished in
writing by or on behalf of such Selling Holder expressly for inclusion in the

13

 

Resale Registration Statement, any preliminary prospectus, prospectus supplement, free writing
prospectus or final prospectus contained therein, or any amendment or supplement thereof; provided,
however, that the liability of each Selling Holder shall not be greater in amount than the dollar
amount of the proceeds (net of any Selling Expenses) received by such Selling Holder from the sale
of the Registrable Securities giving rise to such indemnification.

          (c) Notice. Promptly after receipt by an indemnified party hereunder of notice of the
commencement of any action, such indemnified party shall, if a claim in respect thereof is to be
made against the indemnifying party hereunder, notify the indemnifying party in writing thereof,
but the omission so to notify the indemnifying party shall not relieve it from any liability which
it may have to any indemnified party other than under this Section 2.8. In any action brought
against any indemnified party, it shall notify the indemnifying party of the commencement thereof.
The indemnifying party shall be entitled to participate in and, to the extent it shall wish, to
assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified
party and, after notice from the indemnifying party to such indemnified party of its election so to
assume and undertake the defense thereof, the indemnifying party shall not be liable to such
indemnified party under this Section 2.8 for any legal expenses subsequently incurred by such
indemnified party in connection with the defense thereof other than reasonable costs of
investigation and of liaison with counsel so selected; provided, however, that, (i) if the
indemnifying party has failed to assume the defense or employ counsel reasonably acceptable to the
indemnified party or (ii) if the defendants in any such action include both the indemnified party
and the indemnifying party and counsel to the indemnified party shall have concluded that there may
be reasonable defenses available to the indemnified party that are different from or additional to
those available to the indemnifying party, or if the interests of the indemnified party reasonably
may be deemed to conflict with the interests of the indemnifying party, then the indemnified party
shall have the right to select a separate counsel and to assume such legal defense and otherwise to
participate in the defense of such action, with the reasonable expenses and fees of such separate
counsel and other reasonable expenses related to such participation to be reimbursed by the
indemnifying party (provided appropriate documentation for such expense is also submitted with such
notice) as incurred; provided however, that the indemnified party will be required
to repay the indemnifying party any amounts paid to it for which it is determined the indemnified
party was not otherwise entitled within five calendar days of such determination. Notwithstanding
any other provision of this Agreement, no indemnifying party shall settle any action brought
against any indemnified party with respect to which such indemnified party is entitled to
indemnification hereunder without the consent of the indemnified party, unless the settlement
thereof imposes no liability or obligation on, and includes a complete and unconditional release
from all liability of, the indemnified party.

          (d) Contribution. If the indemnification provided for in this Section 2.8 is held by
a court or government agency of competent jurisdiction to be unavailable to any indemnified party
or is insufficient to hold them harmless in respect of any Losses, then each such indemnifying
party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or
payable by such indemnified party as a result of such Loss in such proportion as is appropriate to
reflect the relative fault of the indemnifying party on the one hand and of such indemnified party
on the other in connection with the statements or omissions which resulted in such Losses, as well
as any other relevant equitable considerations; provided, however, that in no event shall such
Selling Holder be required to contribute an aggregate amount in excess of the

14

 

dollar amount of proceeds (net of Selling Expenses) received by such Selling Holder from the
sale of Registrable Securities giving rise to such indemnification. The relative fault of the
indemnifying party on the one hand and the indemnified party on the other shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact has been made by, or relates to,
information supplied by such party, and the parties’ relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission. The parties hereto
agree that it would not be just and equitable if contributions pursuant to this paragraph were to
be determined by pro rata allocation or by any other method of allocation which does not take
account of the equitable considerations referred to herein. The amount paid by an indemnified
party as a result of the Losses referred to in the first sentence of this paragraph shall be deemed
to include any legal and other expenses reasonably incurred by such indemnified party in connection
with investigating or defending any Loss which is the subject of this paragraph. No person guilty
of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall
be entitled to contribution from any Person who is not guilty of such fraudulent misrepresentation.

          (e) Other Indemnification. The provisions of this Section 2.8 shall be in addition to
any other rights to indemnification or contribution which an indemnified party may have pursuant to
law, equity, contract or otherwise.

     Section 2.9 Rule 144 Reporting. With a view to making available the benefits of
certain rules and regulations of the Commission that may permit the sale of the Registrable
Securities to the public without registration, the Partnership agrees to use its commercially
reasonable efforts to:

          (a) Make and keep public information regarding the Partnership available, as those terms are
understood and defined in Rule 144 of the Securities Act, at all times from and after the date
hereof;

          (b) File with the Commission in a timely manner all reports and other documents required of
the Partnership under the Securities Act and the Exchange Act at all times from and after the date
hereof; and

          (c) So long as a Holder owns any Registrable Securities, furnish, unless otherwise available
at no charge by access electronically to the Commission’s EDGAR filing system, to such Holder
forthwith upon request a copy of the most recent annual or quarterly report of the Partnership, and
such other reports and documents so filed with the Commission as such Holder may reasonably request
in availing itself of any rule or regulation of the Commission allowing such Holder to sell any
such securities without registration.

If the Partnership fails for any reason to comply with the provisions of this Section 2.9 during
the period beginning on the date which is six months from the Closing Date and ending one year from
the Closing Date which prohibits a Holder from selling Purchased Units or the Converted Class C
Units, as applicable, then held by such Holder pursuant to Rule 144 under the Securities Act for
more than 20 days in the aggregate, then the Partnership shall pay to each such Holder (to the
extent such Holders Purchased Units or Class C Units, as applicable, are not otherwise

15

 

included on a Resale Registration Statement pursuant to Section 2.1) an amount equal to 0.25% times
the Liquidated Damages Multiplier for each 30 days in excess of such 20 days during which such
Holder is unable to sell the Purchased Units or the Converted Class C Units, with such payment
amount increasing by an additional amount equal to 0.25% times the Liquidated Damages Multiplier
per additional 30 days up to a maximum of 1% times the Liquidated Damages Multiplier; provided,
that the aggregate amount of Liquidated Damages payable by the Partnership per Purchased Unit may
not exceed 5.0% of the Class C Unit Price. All of the provisions in Section 2.1(b) with respect to
the payment of the Liquidated Damages, including but not limited to the ability to issue additional
Class C Units in lieu of cash payments, the time period in which payments are due, and the
determination of the number of Class C Units to issue as Liquidated Damages shall be applicable to
the Liquidated Damages payable hereunder.

     Section 2.10 Transfer or Assignment of Registration Rights. The rights to cause the
Partnership to register Registrable Securities granted to the Purchasers by the Partnership under
this Article II will be transferable or assignable by each Purchaser to an Affiliate of such
Purchaser or to a transferee or assignee of Registrable Securities, provided (a) the amount of
Registrable Securities transferred or assigned to a Person who is not an Affiliate must represent
at least $10.0 million, based on the Class C Unit Price, (b) the Partnership is given written
notice prior to any such transfer or assignment, stating the name and address of each such
transferee and identifying the securities with respect to which such registration rights are being
transferred or assigned, and (c) each such transferee agrees in writing to undertake responsibility
for its portion of the obligations of such Purchaser under this Agreement.

     Section 2.11 Limitation on Subsequent Registration Rights. From and after the date
hereof, the Partnership shall not, without the prior written consent of the Holders of a majority
of the outstanding Registrable Securities, enter into any agreement with any current or future
holder of any securities of the Partnership that would allow such current or future holder to
require the Partnership to include securities in any registration statement filed by the
Partnership on a basis other than pari passu with, or expressly subordinate to, the priority rights
set forth in Section 2.2(b) granted to the Holders of Registrable Securities hereunder.

hereof or affecting or impairing the validity or enforceability of such provision in any other
jurisdiction.

expression of their agreement and intended to be a complete and exclusive statement of the
agreement and understanding of the parties hereto in respect of the subject matter contained
herein. There are no restrictions, promises, warranties or undertakings, other than those set
forth or referred to herein with respect to the rights granted by the Partnership set forth herein.
This Agreement and the Purchase Agreement supersede all prior agreements and understandings
between the parties with respect to such subject matter.

     Section 3.12 Amendment. This Agreement may be amended only by means of a written

or limited partner, manager, member, stockholder or Affiliate of any of the foregoing, as such, for
any obligations of the Purchasers under this Agreement or any documents or instruments delivered in
connection herewith or therewith or for any claim based on, in respect of or by reason of such
obligation or its creation, except in each case for any assignee of a Purchaser hereunder.

	9.	 	Plan of distribution:
	 
	 	 	 Except as set forth below, the undersigned (including its donees or
pledgees) intends to distribute the Registrable Securities listed
above in Item (3) pursuant to the Resale Registration Statement only
as follows (if at all): Such Registrable Securities may be sold from
time to time directly by the undersigned or alternatively through
underwriters or broker-dealers or agents. If the Registrable
Securities are sold through underwriters or broker-dealers, the
Selling Unitholder will be responsible for underwriting discounts or
commissions or agents’ commissions and their professional fees. Such
Registrable Securities may be sold in one or more transactions at
fixed prices, at prevailing market prices at the time of sale, at
varying prices determined at the time of sale, or at negotiated
prices. Such sales may be effected in transactions (which may involve
block transactions) (i) on any national securities exchange or
quotation service on which the Registrable Securities may be listed or
quoted at the time of sale, (ii) in the over-the-counter market, (iii)
in transactions otherwise than on such exchanges or services or in the
over-the-counter market or (iv) through the writing of options. In
connection with the sales of Registrable Securities or otherwise, the
undersigned may enter into hedging transactions with broker-dealers,
which may in turn engage in short sales of Registrable Securities in
the course of hedging positions they assume. The undersigned may also
sell Registrable Securities short and deliver Registrable Securities
to close out short positions, or loan or pledge Registrable Securities
to broker-dealers that in turn may sell such securities. The Selling
Unitholder may pledge or grant a security interest in some or all of
the Registrable Securities owned by it and, if it defaults in the
performance of its secured obligations, the pledgees or secured
parties may offer and sell the Registrable Securities from time to
time. The Selling Unitholder also may transfer and donate Registrable
Securities in other circumstances in which case the transferees,
donees, pledgees or other successors in interest will be the Selling
Unitholder for purposes of the prospectus.
	 
	 	 	State any exceptions here:
	 	 	 
	 	 	 
	 	 	 
	 
	 	 	Note: In no event will such method(s) of distribution take the form
of an underwritten offering of the Registrable Securities without the
prior agreement of the Partnership.

     (d) The Parties acknowledge and agree that Seller has purchased and owns the pipeline
inventory described in Exhibit E-1 attached hereto for the Texas System and in Exhibit
E-2 attached hereto for the Arkansas System (collectively, the “Pipeline Inventory”). Such
Pipeline Inventory is stored at Seller’s yard(s) and/or in the yard of its pipeline vendor or its
pipe vendor’s coater (collectively, the “Yards”), and pipe will be removed from the Yards and the
Pipeline Inventory from time-to-time (both before and after the Effective Time) by Seller for use
in expansion of the Systems; provided, however, pipe will be removed from the Yards and the
Pipeline Inventory after the Effective Time only as utilized in the AFE Projects. The Pipeline
Inventory Estimated Cost represents the total of the actual, direct costs paid by Seller and/or its
Affiliates for the Pipeline Inventory estimated to be remaining in the Yards at the Effective Time.
The Purchase Price shall be adjusted after Closing as provided below in this Article 3 by the
difference between (the “Pipeline Inventory Cost Difference”): (i) the Pipeline Inventory Estimated
Cost; and, (ii) the amount (the “Pipeline Inventory Actual Cost”) of the actual, direct costs paid
by Seller and/or its Affiliates for the Pipeline Inventory actually remaining in the Yards at the
Effective Time. Under the Settlement Statement and Sections 3.01(f) and (g) below, if the Pipeline
Inventory Actual Cost is greater than the Pipeline Inventory Estimated Cost, Buyer shall pay the
Pipeline Inventory Cost Difference to Seller, or, if the Pipeline Inventory Actual Cost is less
than the Pipeline Inventory Estimated Cost, Seller shall pay the Pipeline Inventory Cost Difference
to Buyer.

16

 

     (e) The Parties acknowledge and agree that the fees charged for treatment of CO2 under
the Treating Agreements (the “Treating Fees”) are subject to annual true-up each year to account
for the Annual Costs incurred by Seller during the preceding calendar year to treat gas on the
applicable portion of the Arkansas System. Seller is currently in the process of determining this
true-up for the Annual Costs incurred during calendar year 2010, which true-up will be applied to
the Treating Fees charged during calendar year 2011. The Purchase Price shall be adjusted after
Closing as provided below in this Article 3 by either (as applicable, the “Treating Cost
Difference”): (i) the Excess Costs determined in accordance with the Treating Agreements for
calendar year 2010 or (ii) the Underage Costs determined in accordance with the Treating Agreements
for calendar year 2010, whichever applies. Under the Settlement Statement and Sections 3.01(f) and
(g) below, if the true-up for calendar year 2010 determines there were Excess Costs for such year,
Buyer shall pay the Treating Cost Difference to Seller, or, if the true-up for calendar year 2010
determines there were Underage Costs for such year, Seller shall pay the Treating Cost Difference
to Buyer.

     (f) As soon as commercially practicable, but not later than 90 days after the Closing Date,
Seller shall prepare and deliver to Buyer a statement (the “Settlement Statement”) setting forth:
(i) calculation of the AFE Actual Cost and the AFE Cost Difference owed by Seller or Buyer, as the
case may be; (ii) calculation of the Pipeline Inventory Actual Cost and the Pipeline Inventory Cost
Difference owed by Seller or Buyer, as the case may be; (iii) calculation of the Annual Costs for
calendar year 2010 and the Treating Cost Difference owed by Seller or Buyer, as the case may be;
and (iv) the amount of the Receipts and Expenses to be accounted for in accordance with Section
10.04 hereof. As may be requested by either Party, Buyer or Seller, as applicable, shall promptly
furnish to the requesting Party all information that it or its Affiliates may have that is useful
to Buyer or Seller, as applicable, in the calculation or verification of the Settlement Statement.
On or before the thirtieth (30th) day after receipt of the Settlement Statement, or the
first Business Day thereafter if such thirtieth (30th) day is a not a Business Day,
Seller shall pay any and all amounts as shown to be owed by Seller to Buyer under the Settlement
Statement or Buyer shall pay any and all amounts as shown to be owed by Buyer to Seller under the
Settlement Statement, less any amounts that Buyer disputes as owing to Seller under the Settlement
Statement.

     (g) Should Buyer dispute any amount shown as payable by Buyer or payable by Seller under the
Settlement Statement, Buyer shall deliver to Seller a written report (the “Objection Report”)
containing any changes that Buyer proposes to be made to the Settlement Statement no later than
thirty (30) days after Buyer’s receipt of the Settlement Statement. If Buyer provides a notice of
agreement or does not deliver an Objection Report to Seller within such 30-day period, then Buyer
shall be deemed to have accepted the calculations and amounts set forth in the Settlement Statement
delivered by Seller, which shall then be final, binding and conclusive for all purposes hereunder.
In the event Buyer does deliver an Objection Report to Seller within such 30-day period, Buyer and
Seller shall undertake to agree upon a final resolution of the amounts owing under the Settlement
Statement not later than 150 days after the Closing Date should Buyer dispute any amount
thereunder. If Buyer timely proposes changes to the Settlement Statement and thereafter Seller and
Buyer are unable to agree upon the final resolution Settlement Statement within 150 days after the
Closing Date, a mutually acceptable, nationally recognized, accounting firm not performing services
for either Buyer or Seller shall be designated to act as an arbitrator and to decide all points of
disagreement with respect to the

17

 

Settlement Statement, such decision to be binding upon both Parties. The costs and expenses
of the arbitrator shall be shared equally by Seller and Buyer pursuant to the arbitrator’s standard
engagement letter. If the Settlement Statement, after resolution of all disputes, reflects an
amount due to Seller, Buyer shall, within five (5) Business Days, pay to Seller in immediately
available funds such amount, less any amounts already paid under Section 3.01(f). If the
Settlement Statement, after resolution of all disputes, reflects an amount due to Buyer, Seller,
shall within five (5) Business Days, pay to Buyer, in immediately available funds such amount, less
any amounts already paid under Section 3.01(f).

     3.02 New BP Contract. The Parties acknowledge and agree that Seller is in the process of
negotiating with BP a definitive gas gathering and processing agreement with respect to the Texas
System (the “New BP Contract”). Seller shall before Closing, and Seller and Buyer shall jointly
after Closing, in good faith, continue such negotiations with BP and shall use their commercially
reasonable efforts and reasonable diligence to finalize the New BP Contract with BP by the
180th day after the Closing Date (the “BP Contract Deadline”), with such terms and
conditions as are normal and customary for contracts of such nature; provided, however, that Buyer
shall have the right to consent to and approve the New BP Contract prior to Closing pursuant to
Section 4.02(d), such consent and approval not to be unreasonably withheld or delayed. If the
Parties finalize any New BP Contract with BP on or before the BP Contract Deadline, Buyer shall
execute such New BP Contract as soon as possible, but not earlier than the Closing Date or later
than the BP Contract Deadline, and (i) if such New BP Contract contains Gross Margin Actual Terms
that are equal to or greater than the Gross Margin Expected Terms, Buyer shall pay Seller the BP
Additional Payment Amount, within five (5) Business Days after execution of the New BP Contract, by
wire transfer of immediately available funds to bank accounts designated in writing by Seller to
Buyer, or (ii) if such New BP Contract contains Gross Margin Actual Terms that are less than the
Gross Margin Expected Terms, Buyer shall pay Seller a portion of the BP Additional Payment Amount,
within five (5) Business Days after execution of the New BP Contract, by wire transfer of
immediately available funds to bank accounts designated in writing by Seller to Buyer determined as
follows:

     (a) Seller shall be entitled to receive the amount (the “BP Contract Value”) equal to the
product of the BP Additional Payment Amount multiplied by a fraction, expressed as a percentage,
the numerator of which is the Gross Margin Actual Terms and the denominator of which is the Gross
Margin Expected Terms; and

     (b) Buyer shall be entitled to retain the remainder of the BP Additional Payment Amount.

A simplified example of calculation of the BP Contract Value is set forth on Exhibit K
attached hereto. However, if the Parties fail to finalize the New BP Contract with BP on or before
the BP Contract Deadline, Buyer shall retain the BP Additional Payment Amount, unless such failure
is caused by a breach by Buyer of its obligations under this Section to use commercially reasonable
efforts and reasonable diligence to finalize the New BP Contract by the BP Contract Deadline, in
which event the BP Contract Deadline shall be extended for an additional one hundred eighty (180)
days after the BP Contract Deadline.

18

 

     3.03 Allocation of Purchase Price. The Purchase Price shall be allocated among the assets
of Seller in accordance with Schedule 3.03 (the “Allocation”). Seller and Buyer shall
report the transaction contemplated hereby on all Tax Returns, including, but not limited to Form
8594, in a manner consistent with the Allocation. After Closing, if the adjusted purchase price
(as computed under the Settlement Statement and Sections 3.01(f) and (g)) differs from the initial
purchase price (as computed under Section 3.01(a)) and if such difference requires an adjustment to
the Allocation in order for such Allocation to comply with Section 1060 of the Code and the
Treasury Regulations thereunder, Seller shall prepare such adjustment to the Allocation which
adjustment shall be submitted to Buyer, and Seller and Buyer shall use their reasonable efforts to
agree on the final adjustment within thirty (30) days after the determination of the adjusted
purchase price. Buyer shall timely and properly prepare, execute, file, and deliver all such
documents, forms, and other information as Seller may reasonably request in preparing any required
adjustment to the Allocation. If, contrary to the intent of the parties hereto as expressed in
this Section 3.03, any Taxing authority makes or proposes an allocation different from the
Allocation determined under this Section 3.03, Seller and Buyer shall cooperate with each other in
good faith to contest such Taxing authority’s allocation (or proposed allocation), provided,
however, that, after consultation with the party (or parties) adversely affected by such allocation
(or proposed allocation), the other party (or parties) hereto may file such protective claims or
Tax Returns as may be reasonably required to protect its (or their) interests.

ARTICLE 4

CLOSING

     4.01 Time and Place of Closing. Subject to the terms and conditions stated in this Agreement,
the consummation of the transactions contemplated hereby (the “Closing”) shall occur (a) three (3)
Business Days after the satisfaction or waiver of each Party’s closing conditions as set forth in
Section 8.01 and Section 8.02, or (b) on such other date as the Parties may mutually agree in
writing; provided, however, that if the Marketing Period has not ended at the time of the
satisfaction or, to the extent permitted, waiver of conditions set forth in Article 8 (other than
those conditions that by their terms are to be satisfied at the Closing, but subject to the
satisfaction or, to the extent permitted, waiver of such conditions at the Closing), the Closing
shall occur on the date following the satisfaction or waiver of such conditions that is the
earliest to occur of (x) a date during the Marketing Period to be specified by Buyer on no less
than two (2) Business Days’ notice to Seller (it being understood that such date may be conditioned
upon the simultaneous completion of the Debt Financing) or (y) the third (3rd) Business
Day after the final day of the Marketing Period or (b) at such other place, time and date as shall
be agreed by the Parties. The Closing shall be held at the offices of the law firm of Hall,
Estill, Hardwick, Gable, Golden & Nelson, P.C., located at 320 South Boston Ave., Suite 200, Tulsa,
Oklahoma. The date on which the Closing occurs is referred to in this Agreement as the “Closing
Date”.

     4.02 Pre-Closing.

     (a) If approval of the transaction contemplated by this Agreement is required under the HSR
Act, from the date of this Agreement until the Closing, each of Buyer and Seller shall, and shall
cause their respective Affiliates to: (i) use reasonable efforts to make or cause to be

19

 

made the filings required of such Party or any of its Affiliates under the HSR Act with
respect to the transactions contemplated by this Agreement no later than February 25, 2011, and
take any action necessitated by such filings as promptly as is reasonably practicable; (ii)
cooperate with the other Party and furnish all information in such Party’s possession that is
necessary in connection with such other Party’s filings; (iii) use reasonable efforts to cause the
expiration of the notice or waiting periods under the HSR Act with respect to the transactions
contemplated hereby as promptly as reasonably possible; (iv) promptly inform the other Party of any
communication from or to, and any proposed understanding or agreement with, any Governmental Entity
in respect of such filings; (v) consult and cooperate with the other Party in connection with any
analyses, appearances, presentations, memoranda, briefs, arguments and opinions made or submitted
by or on behalf of any Party in connection with all meetings, actions and proceedings with any
Governmental Entity relating to such filings; (vi) comply, as promptly as is reasonably
practicable, with any requests received by such Party or any of its Affiliates under the HSR Act or
any related Legal Requirements for additional information, documents or other materials; (vii) use
reasonable efforts to resolve any objections as may be asserted by any Governmental Entity with
respect to the transactions contemplated by this Agreement; and, (viii) use reasonable efforts to
contest and resist any action or proceeding instituted (or threatened in writing to be instituted)
by any Governmental Entity challenging the transactions contemplated by this Agreement as violative
of the HSR Act or any other Legal Requirement. If a Party intends to participate in any meeting
with any Governmental Entity with respect to such filings, it shall give the other Party reasonable
prior notice of, and an opportunity to participate in, such meeting. The Buyer shall pay in full
the initial filing fee, and shall pay in full when due any applicable fees required under the HSR
Act.

     (b) Until the earlier of the Closing Date or termination of this Agreement, Buyer shall have
reasonable access to the business, properties and employees of Seller and information concerning
its financial and legal condition of the ownership and operation of the Purchased Assets and
Assumed Liabilities, provided that such access shall not interfere with normal operations of
Seller. Seller agrees to permit Buyer and its authorized representatives, or cause them to be
permitted, to have, after the date hereof and until the earlier of the Closing Date or termination
of this Agreement, reasonable access to the Records during normal business hours, and the officers
of Seller will furnish Buyer with such existing financial and operating data and other information
in Seller’s possession with respect to the Purchased Assets as Buyer shall from time to time
reasonably request. In addition, Seller shall provide Buyer a copy of its audited financial
statement for 2009 and shall use its commercially reasonable efforts to deliver to Buyer a copy of
its audited financial statement for 2010 no later than February 22, 2011. For the avoidance of
doubt, nothing in this Section shall obligate Seller to create or prepare any new data, documents
or other information, except the foregoing audited financial statement for 2010. Buyer shall
coordinate all of its requests for such access through Seller, and shall provide reasonable advance
notice of such request. If, prior to or at the time of Closing, Buyer, its Affiliates, or its or
their respective employees have knowledge of any breach of Seller’s representations, warranties or
covenants contained in this Agreement, Buyer shall promptly notify Seller of same, including
reasonable details of the circumstances giving rise to such breach; provided, that, (i) Buyer shall
not have any liability to Seller or its Affiliates for any failure of Buyer to so notify Seller,
and (ii) no investigation by Buyer heretofore or hereafter made, or knowledge by Buyer, its
Affiliates or its or their respective employees of any of breach of Seller’s representations,
warranties or covenants, shall affect the representations, warranties

20

 

and covenants of Seller or Buyer’s right to indemnification as provided in this Agreement, and
each such representation, warranty and covenant shall survive any such investigation.

     (c) Seller shall, subject to Section 2.01(e), use its reasonable efforts to obtain the
Required Consents, and Buyer shall provide Seller with any information and assistance reasonably
requested by Seller in relation thereto. Except for those consents and approvals listed on
Schedule 8.01(f) which are required to be obtained prior to Closing, to the extent any of
the Required Consents are not obtained prior to Closing with respect to any Purchased Asset (a
“Non-Assigned Asset”), the Closing shall not be delayed due to failure to obtain any such Required
Consent, such Non-Assigned Asset shall not be conveyed to Buyer at Closing, and upon the Closing
such Non-Assigned Asset shall be deemed to be held by Seller at all times during the Holding Period
for the benefit of Buyer in accordance with this Section. During the Holding Period, Seller shall,
and shall cause its Affiliates to, grant to Buyer an exclusive right and license to use each such
Non-Assigned Asset and provide Buyer with the economic benefits and risks of ownership of the
Non-Assigned Assets, and Seller shall use commercially reasonable efforts to obtain the Required
Consent related to such Non-Assigned Assets, the intent of the Parties being to provide Buyer, to
the extent the same can be reasonably done, with the same access and ability to utilize such
Non-Assigned Assets as if such Non-Assigned Assets had been included within the Purchased Assets.
Seller will promptly pay to Buyer when received all monies received by Seller under any
Non-Assigned Asset or any claim or right or any benefit arising thereunder to the extent
attributable to the Holding Period (net of any amounts for which Seller is entitled to be
reimbursed pursuant to this Section). Buyer shall pay, perform and discharge, fully and promptly
when due, all the obligations of Seller under such Non-Assigned Asset from and after the Closing
Date, and Buyer shall indemnify, defend and hold harmless the Seller Indemnified Parties from and
against any and all Damages that arise out of, result from or are payable as a result of Buyer’s or
any of its Affiliates’ performance, breach or default under, operation of, or conditions existing,
arising or occurring with respect to, any Non-Assigned Asset. For purposes of this Agreement, if
the Non-Assigned Asset is an easement or similar right, then the term Non-Assigned Asset shall
include the portion of the associated Improvements located thereon. Upon receipt of the Required
Consent related to a Non-Assigned Asset, Seller shall assign such Non-Assigned Asset to Buyer using
the same form of conveyance which would have been used had the Non-Assigned Asset been assigned at
the Closing, and without the payment of any additional consideration. For purposes of this
Agreement, the term “Holding Period,” for any particular Non-Assigned Asset, shall mean the period
beginning on the Closing Date and ending on the earlier of (i) the date upon which the Contract for
which the Required Consent was not obtained expires or otherwise terminates or (ii) the date upon
which such Required Consent or an alternative arrangement is obtained on terms that are
substantially similar in operational and economic effects as the assignment of the Non-Assigned
Asset to Buyer.

     (d) From the date of this Agreement until Closing, Seller shall operate its business and
maintain the Purchased Assets in the ordinary course and substantially in accordance with its past
operating and maintenance practices, and Seller shall not, and shall cause its Affiliates not to,
without the prior written consent of Buyer (which shall not be unreasonably withheld or delayed):
(i) other than in the ordinary course of business (which shall include Seller’s field personnel
bonus program), grant any bonus to or increase any salary or other compensation or benefits of any
Eligible Employee; (ii) sell, assign, transfer, lease, relocate, terminate, release,

21

 

close, abandon or otherwise dispose of any of the Purchased Assets, but Seller may dispose of
tangible personal property with a value less than $100,000 to the extent replaced by equivalent
property or used or consumed in the normal operations of the Purchased Assets, and Seller may
dispose of natural gas, natural gas liquids and other products pursuant to the Contracts and the
Excluded NAESB Contracts; (iii) make any individual capital expenditure or commitment related to
the Purchased Assets in excess of $100,000 to the extent Buyer will be liable or responsible for
same, provided, however, this limitation shall not apply (A) to expenditures for the AFE Projects
under the AFEs, except to the extent expenditures with respect to a line item amount set forth in
the AFEs will exceed such line item amount by more than $100,000, or (B) to situations believed in
good faith by Seller to constitute an emergency (in which case Seller’s obligation is limited to
notifying Buyer as soon as reasonably practicable of such emergency and obligations); (iv) amend,
assign, transfer, waive any rights under, terminate or otherwise dispose of any of the Contracts or
enter into any new contracts or agreements related to the Purchased Assets, except for the
Transition Services Agreement and any new easements, rights-of-way, surface use agreements, surface
lease agreements, line rights or real property licenses acquired by Seller with respect to the
Purchased Assets or any extensions thereto during the period from and after the date of this
Agreement until the Closing Date consistent with its past practices and requiring payment of less
than $25,000 in each individual instance to acquire (collectively, the “New Easements”); (v)
terminate the employment with Seller or its Affiliates of any of the Eligible Employees other than
for cause; (vi) liquidate, dissolve, recapitalize or otherwise wind up its business; (vii) merge or
consolidate with, or purchase substantially all of the assets or business of, or equity interests
in, or make an investment in any Person; or (viii) agree, whether in writing or otherwise, to do
any of the foregoing. In the event Seller acquires New Easements prior to Closing, Seller shall,
by written notice to Buyer, add such New Easements to Schedule 2.01(b)(i)(B), and such New
Easements shall be included as Easements and Purchased Assets hereunder. For the avoidance of
doubt, such addition of New Easements to Schedule 2.01(b)(i)(B) shall not constitute
grounds for termination of this Agreement by Buyer under Section 8.03(d).

     (e) From and after the date of this Agreement until the Closing Date, Seller shall provide
such reasonable cooperation, information and documentation as may be reasonably requested by Buyer
and that is customary in connection with a financing comparable to the Debt Financing, including
(i) furnishing to Buyer and its Lending Sources, as promptly as practicable all financial, business
and other pertinent information related to Seller reasonably required by Buyer for Buyer to produce
the financial statements and other offering document information, including all financial
statements (including audited financial statements for fiscal years 2008, 2009 and 2010) and pro
forma financial statements in the form required by Regulation S-X under the Securities Act and of
the type and in the form customarily included in an offering memorandum under Rule 144A to
consummate the Debt Financing (information required to be delivered pursuant to this clause (i),
the “Required Information”); (ii) to the extent reasonably requested by Buyer or its Lending
Sources, requesting any consents of accountants for use of their reports in any materials relating
to the Debt Financing and the delivery of one or more customary representation letters and
executing and/or delivering all appropriate definitive documents to assist in consummation of the
Debt Financing; and (iii) taking corporate actions by Seller reasonably necessary to permit the
completion of the Debt Financing; provided, however, that, except as otherwise provided in Section
4.04, none of Seller or its Affiliates, shall be required to pay any commitment or other similar
fee or incur any other liability in connection

22

 

with the Transaction Financing. Buyer shall promptly, upon request by Seller following the
Closing or termination of this Agreement, reimburse Seller for all out-of-pocket costs and expenses
(including outside attorneys’ fees) incurred by Seller or its Affiliates, in connection with the
cooperation contemplated by this Section 4.02. All non-public information regarding Seller and its
Affiliates provided to Buyer, its Affiliates or its representatives pursuant to this Section 4.02
shall be kept confidential, except that Buyer shall be permitted to disclose such information to
potential lenders, investors, rating agencies or their respective Representatives in connection
with the Debt Financing, subject to obtaining customary confidentiality commitments.

     (f) Buyer acknowledges and agrees that the Seller Indemnified Parties shall not have any
responsibility for, or incur any Liability to any Person under, the Transaction Financing or any
other financing that Buyer may raise in connection with the transactions contemplated by this
Agreement or any cooperation provided pursuant to Section 4.02(e) (other than, in the case of
Seller, liability to Buyer for breach of Seller’s obligations under Section 4.02(e)) and Seller’s
obligations under Section 4.04, and that Buyer shall indemnify, defend, hold harmless and release
the Seller Indemnified Parties from and against any and all Claims and Damages that arise out of,
result from or are payable in connection with the Transaction Financing or such other financing,
and any information utilized in connection therewith, IN EACH CASE WITHOUT REGARD TO THE SOLE,
PARTIAL OR CONCURRENT NEGLIGENCE, GROSS NEGLIGENCE OR STRICT LIABILITY (BUT NOT THE WILLFUL AND
WANTON MISCONDUCT) OF THE SELLER INDEMNIFIED PARTIES.

     4.03 Closing Obligations. At the Closing, the following events shall occur:

     (a) The Parties shall execute, acknowledge and deliver (i) one or more Warranty Deeds
conveying to Buyer the Fee Property, (ii) an Assignment and Assumption conveying to Buyer the
Easements, and (iii) an Assignment, Assumption and Bill of Sale conveying to Buyer the other

     (b) Buyer shall pay the Purchase Price (as adjusted for Seller’s prorated share of Property

     (c) Seller shall deliver to Buyer payoff letters and mortgage releases in recordable form and
form UCC-3s in recordable form to release any Encumbrances filed against the Purchased Assets

the Unit Purchase Agreement(s) a termination fee equal to one percent (1.0%) of the aggregate
purchase price for the Class C Units such purchaser is committed to purchase pursuant to the Unit

Termination Fee, Seller shall, within five (5) Business Days after Seller’s receipt of a statement
therefor from Buyer, together with reasonable supporting documentation, reimburse Buyer by wire
transfer of immediately available funds to such account as designated by Buyer an amount equal to

ARTICLE 5

REPRESENTATIONS AND WARRANTIES OF SELLER

     Subject to the survival provisions set forth in Article 9 and the limitations provided for in
Article 10, Seller hereby represents and warrants to Buyer that the following are true and correct
as of the date hereof and will be true and correct as of the Closing Date:

     5.01 Organization and Qualification. Seller is a limited liability company duly organized,
validly existing and in good standing under the laws of the State of Delaware. Seller has all
requisite limited liability company power and authority to carry on its business as now being
conducted and to own, lease and operate its properties and assets as now owned, leased or operated,
and to perform all its obligations under the agreements and instruments to which it is a party or
by which it is bound.

     5.02 Approval and Enforceability. The execution and delivery of this Agreement by Seller and
the performance of the transactions contemplated hereunder by Seller have been duly and validly
approved by all requisite company or partnership action, as applicable, necessary on behalf of
Seller. This Agreement constitutes the legal, valid and binding obligation of Seller,

24

 

enforceable against Seller in accordance with its terms, subject to applicable bankruptcy,
insolvency or other similar laws relating to or affecting the enforcement of creditors’ rights
generally and to general principles of equity (“Creditors’ Rights”). At the Closing, all documents
required hereunder to be executed and delivered by Seller will have been duly authorized, executed
and delivered by Seller and will constitute legal, valid and binding obligations of Seller,
enforceable against Seller in accordance with its terms, subject to Creditors’ Rights.

     5.03 Consents and Approvals; No Violation. Except as set forth in Schedule 5.03, the
execution and delivery of this Agreement by Seller and the consummation by Seller of the
transactions contemplated hereby will not:

     (a) entitle any Person to exercise any preferential purchase right, option to purchase or
similar right with respect to any of the Purchased Assets;

     (b) conflict with or violate any provision of any organizational document of Seller;

     (c) result in a material violation or material breach of, or constitute (with or without due
notice or lapse of time or both) a material default (or give rise to any right of termination,
cancellation or acceleration) under, any of the terms, conditions or provisions of any note,
Contract, agreement, commitment, bond, mortgage, indenture, license, lease, pledge agreement or
other instrument or obligation to which Seller is a party or by which Seller or any of its
properties or assets may be bound;

     (d) violate or conflict with any provision of any Legal Requirement binding upon Seller;

     (e) result in, or require, the creation or imposition of, any Encumbrance upon or with respect
to any of the assets or properties now owned or used by Seller; or

     (f) require Seller to obtain or make any material waiver, consent, action, approval, clearance
or authorization of, or registration, declaration or filing with, any Governmental Entity, other
than such approval as may be required to be obtained under the HSR Act.

     5.04 Material Contracts.

     (a) Schedule 5.04(a) lists all Material Contracts. Seller has furnished or made
available to Buyer true, complete and correct copies of all written Material Contracts, together
with all amendments thereto. All of the Material Contracts are legal, valid and binding
obligations of the parties thereto, enforceable in accordance with their terms, and are in full
force and effect, subject to Creditors’ Rights. Except as set forth in the footnotes to Schedule
5.04(a), there are no renegotiations of, or attempts to renegotiate, any amounts paid or payable to
Seller under current Material Contracts with any Person having the contractual or statutory right
to demand or require such renegotiation, and no such Person has made written demand for such
renegotiation.

     (b) Except as set forth in Schedule 5.04(b), to Seller’s Knowledge neither it, nor any
counterparty thereto, is in default under any Material Contract, and no termination, condition or

25

 

other event has occurred which (whether with or without notice, lapse of time or the happening
or occurrence of any other event) could reasonably be expected to constitute a breach or default
thereunder or a basis for force majeure or other claim of excusable delay or non-performance

Article 10, Buyer represents and warrants to Seller that the following are true and correct as of
the date hereof and will be true and correct as of the Closing Date:

     6.01 Organization and Qualification. Buyer is a limited partnership duly organized, validly
existing and is in good standing under the laws of the State of Delaware. Buyer has all requisite
limited partnership power and authority to carry on its business as now being conducted and to own,
lease and operate its properties and assets as now owned, leased or operated, and to perform all
its obligations under the agreements and instruments to which it is a party or by which it is
bound.

     6.02 Approval and Enforceability. The execution and delivery of this Agreement by Buyer and
the performance of the transactions contemplated hereby have been duly and validly approved by all
requisite company or partnership action, as applicable, necessary on behalf of Buyer. This
Agreement constitutes the legal, valid and binding obligation of Buyer, enforceable against Buyer
in accordance with its terms, subject to Creditors’ Rights. At the Closing, all documents required
hereunder to be executed and delivered by Buyer will have been duly authorized, executed and
delivered by Buyer and will constitute legal, valid and binding obligations of Buyer, enforceable
against Buyer in accordance with its terms, subject to Creditors’ Rights.

     6.03 No Violation or Consent. The execution and delivery of this Agreement by Buyer and the
consummation by Buyer of the transactions contemplated hereby will not:

30

 

     (a) result in a material violation or material breach of, or constitute (with or without
due notice or lapse of time or both) a material default (or give rise to any right of termination,
cancellation or acceleration) under, any of the terms, conditions or provisions of any note,
contract, agreement, commitment, bond, mortgage, indenture, license, lease, pledge agreement or
other instrument or obligation to which Buyer is a party or by which Buyer or any of its properties
or assets may be bound; or

     (b) require Buyer to obtain or make any material waiver, consent, action, approval, clearance
or authorization of, or registration, declaration or filing with, any Governmental Entity, other
than such approval as may be required to be obtained under the HSR Act.

     6.04 Brokers. Neither Buyer nor any of its Affiliates has entered (directly or indirectly)
into any agreement with any Person that provides for the payment of any commission, brokerage or
“finders’ fee” arising out of the transactions contemplated by this Agreement for which Seller
might have any Liability or obligation.

     6.05 Litigation. There are no civil, criminal, administrative, arbitration or other
proceedings pending or, to Buyer’s knowledge, threatened against Buyer or any of its Affiliates,
and there are no governmental investigations pending or, to Buyer’s knowledge, threatened against
Buyer, that seek to restrain or enjoin the transactions contemplated by this Agreement

     6.06 Financing. Schedule 6.06 sets forth a true and complete copy of the commitment
letter, dated February 18, 2011, by and among Buyer and UBS Loan Finance LLC, UBS Securities LLC,
BNP Paribas, BNP Paribas Securities Corp., Royal Bank of Canada, RBC Capital Markets, Royal Bank of
Scotland plc., and RBS Securities Inc. (the “Debt Financing Commitment”), pursuant to which the
lenders party thereto have committed to lend the amounts set forth therein for the purposes of
financing the transactions contemplated by this Agreement and related fees and expenses (the “Debt
Financing”); provided, however, that if certain terms of the Debt Financing Commitment are set
forth in fee letters or other agreements, Buyer has provided to Seller, on a confidential basis,
true and complete copies of such fee letters or other agreements that have been redacted to delete
any confidential compensation information. Buyer has provided Seller with a true and complete copy
of the Unit Purchase Agreement(s), pursuant to which the investor(s) listed on the signature pages
thereto have committed to invest the amounts set forth therein (the “Equity Financing” and,
together with the Debt Financing, the “Transaction Financing”). On or prior to the date of this
Agreement, neither the Debt Financing Commitment nor any fee letter or other agreement entered into
in connection therewith has been amended, supplemented or modified, and no such amendment or
modification is contemplated, and as of the date of this Agreement the commitments contained in the
Debt Financing Commitment have not been withdrawn, terminated or rescinded in any respect. Buyer
has fully paid any and all commitment fees or other fees in connection with the Debt Financing
Commitment that are due and payable on or prior to the date of this Agreement. The Debt Financing
Commitment is in full force and effect and is the legal, valid and binding obligations of Buyer
and, to the knowledge of Buyer, of the other parties thereto. There are no conditions precedent or
other contingencies related to the funding of the full amount of the Transaction Financing, other
than as set forth in the Debt Financing Commitment and the Unit Purchase Agreement(s). To the
extent that this Agreement must be in a form acceptable to a lender, arranger or agent, such
lender, arranger or agent has approved this Agreement. As of the date of

31

 

this Agreement, Buyer has no reason to believe that any of the conditions to the Transaction
Financing contemplated by the Debt Financing Commitment or the Unit Purchase Agreement(s) will not
be satisfied or that the Transaction Financing will not be made available to Buyer on the Closing
Date. The Debt Financing Commitment (including the fee letters and other agreements entered into
in connection therewith which have been provided to Seller in redacted form) and the Unit Purchase
Agreement(s) constitute the entire and complete agreements between the parties thereto with respect
to the Transaction Financing.

Transferring Employee’s years of service in the industry (for which Seller or its Affiliate gives
credit for benefits purposes) and level of seniority prior to the Closing Date with Seller and its
Affiliates (including service and seniority with any other employer that was recognized by Seller
or its Affiliates) for purposes of terms of employment and eligibility, vesting and benefit

for providing COBRA coverage for each Transferring Employee and any qualifying beneficiary of any
Transferring Employee electing such coverage in connection with such Transferring Employee’s
termination of employment with Seller or its Affiliate to accept employment with Buyer or otherwise
in connection with the Closing. Buyer shall be responsible for providing COBRA coverage for each
Transferring Employee and any qualified beneficiary of any Transferring Employee who becomes

SURVIVAL

     9.01 Survival. Except as otherwise expressly provided herein, the covenants and obligations
of the Parties under this Agreement shall survive Closing for the applicable statute of limitations
period. The representations and warranties of Buyer under this Agreement shall survive the Closing
for a period of twelve (12) months with the exception that the representations and warranties in

Seller under this Agreement shall survive the Closing for a period of twelve (12) months with the
exception that the representations and warranties in (i) Section 5.11 shall survive the Closing
until thirty (30) days after the expiration of the applicable statute of limitations, and (ii)

Claim and all Damages related thereto.

ADDITIONAL AGREEMENTS OF THE PARTIES

     10.01 Indemnification. (a) Subject to the survival provisions set forth in Article 9 and the
limitations set forth in this Section 10.01(a), from and after Closing Seller shall indemnify,
defend, hold harmless and release Buyer, its Affiliates, and its and their respective directors,
officers, employees, legal counsel, financial advisors and agents (collectively, the “Buyer
Indemnified Parties”) from and against any and all Claims, Liabilities (including STRICT
LIABILITIES ARISING UNDER ENVIRONMENTAL LEGAL REQUIREMENTS OR OTHERWISE) and Damages that arise out
of, result from or are payable as a result of the following:

     (i) the breach of any representation or warranty made by Seller in Article 5 of this
Agreement and in any certificate delivered by Seller at Closing;

     (ii) the failure of Seller to perform any covenant or obligation required to be
performed by it under this Agreement; and

     (iii) any Claims made by non-Affiliate third Persons (including Governmental Entities)
against the Buyer Indemnified Parties to the extent such Claims are attributable to the
Retained Liabilities;

36

 

IN EACH CASE WITHOUT REGARD TO THE SOLE, PARTIAL OR CONCURRENT NEGLIGENCE, GROSS NEGLIGENCE
OR STRICT LIABILITY (BUT NOT THE WILLFUL AND WANTON MISCONDUCT) OF THE BUYER INDEMNIFIED
PARTIES; provided, however, that the obligations of Seller under this Section 10.01(a) shall
be subject to the following limitations:

     (1) Notwithstanding anything to the contrary in this Agreement, Seller shall not be
obligated to indemnify, defend, hold harmless or release the Buyer Indemnified Parties for
any Damages pursuant to Section 10.01(a)(i) to the extent (x) the amount of such Damages
does not exceed One Hundred Fifty Thousand Dollars ($150,000) per individual event or
circumstance (the “Threshold”), provided that any and all breaches of the representations
and warranties of Seller in Section 5.05 and/or 5.06 shall be aggregated for purposes of
determining the amount of such Damages and Seller shall not be obligated to indemnify,
defend, hold harmless or release the Buyer Indemnified Party for any Damages pursuant to
Section 10.01(a)(i) to the extent the amount of such Damages does not exceed Three Hundred
Fifty Thousand Dollars ($350,000) in the aggregate (the “Real Property Threshold”), or (y)
the aggregate amount of such Damages suffered or incurred by the Buyer Indemnified Parties
(i) does not exceed one and a quarter percent (1.25%) of the Purchase Price (the
“Deductible”) or (ii) exceeds ten percent (10%) of the Purchase Price (the “Cap”). The
Parties acknowledge and agree that the intent of the preceding sentence, and this Agreement,
is that all liability and responsibility for Damages amounts below the Threshold and the
Real Property Threshold, Damages amounts below the Deductible and Damages amounts exceeding
the Cap with respect to the matters set forth in Section 10.01(a)(i) above shall be borne by
Buyer; provided however, that the limitations in this Section 10.01(a)(1) shall not apply to
a breach of Sections 5.01, 5.02, 5.03(b), 5.11 and 5.13.

     (2) As a condition precedent to Seller’s obligation to indemnify, defend, hold harmless
and release a Buyer Indemnified Party with respect to any Claims and Damages under this
Section 10.01(a), such Buyer Indemnified Party must deliver to Seller a written Claim Notice
for such Claims and Damages within the applicable survival period. To the extent a Buyer
Indemnified Party fails to deliver to Seller a written Claim Notice within said survival
period, such Buyer Indemnified Party shall be deemed to have waived such Claims and Damages.

     (3) It shall not be necessary for a third party Claim to have been brought or
threatened against a Buyer Indemnified Party for the indemnity obligations of Seller to
apply.

     (b) Subject to the survival provisions set forth in Article 9, from and after Closing Buyer
shall indemnify, defend, hold harmless and release Seller, its Affiliates, and its and their
respective directors, officers, employees, legal counsel, financial advisors and agents
(collectively, the “Seller Indemnified Parties”) from and against any and all Claims, Liabilities
(including STRICT LIABILITIES ARISING UNDER ENVIRONMENTAL LEGAL REQUIREMENTS OR OTHERWISE) and
Damages that arise out of, result from or are payable as a result of the following:

37

 

     (i) the breach of any representation or warranty made by Buyer in Article 6 of this
Agreement and in any certificate delivered by Buyer at Closing;

     (ii) the failure of Buyer to perform any covenant or obligation required to be
performed by it under this Agreement; and

     (iii) any Claims made by non-Affiliate third Persons (including Governmental Entities)
against the Seller Indemnified Parties to the extent such Claims are attributable to the
Assumed Liabilities;

IN EACH CASE WITHOUT REGARD TO THE SOLE, PARTIAL OR CONCURRENT NEGLIGENCE, GROSS NEGLIGENCE
OR STRICT LIABILITY (BUT NOT THE WILLFUL AND WANTON MISCONDUCT) OF THE SELLER INDEMNIFIED
PARTIES; provided, however, it shall not be necessary for a third party Claim to have been
brought or threatened against a Seller Indemnified Party for the indemnity obligations of
Buyer to apply.

     (c) In the event that any Claim for which Seller, on the one hand, or Buyer, on the other hand
(each an “Indemnifying Party”), would be liable to the other Party or another Person indemnified
under this Section 10.01 (each collectively, an “Indemnified Party”) is asserted against or sought
to be collected from such Indemnified Party by a non-Affiliate third Person, the Indemnified Party
shall notify the Indemnifying Party in writing of such Claim promptly after becoming aware of such
Claim, specifying the nature of and specific basis for such Claim and the amount or the estimated
amount thereof to the extent then feasible (the “Claim Notice”); provided, however, that no failure
or delay in the giving of such Claim Notice shall relieve the Indemnifying Party of any Liability
hereunder, except to the extent the Indemnifying Party is prejudiced by such omission or delay.
The Indemnifying Party shall have thirty (30) days from the delivery of the Claim Notice (the
“Notice Period”) to notify the Indemnified Party whether or not it desires, at the sole cost and
expense of the Indemnifying Party, to defend the Indemnified Party against such Claim; provided,
however, that any Indemnified Party is hereby authorized during the Notice Period, after giving
additional notice to the Indemnifying Party, to file any motion, answer or other pleading necessary
to protect its interests or those of the Indemnifying Party and not prejudicial to the defense of
such Claim. If the Indemnifying Party notifies the Indemnified Party within the Notice Period that
it desires to defend the Indemnified Party against such Claim, then the Indemnifying Party shall,
at its own expense, assume the defense of any such Claim either directly or through its insurer.
In such case, but subject to Section 10.01(d) below, the Indemnifying Party shall control the
course of and make all decisions concerning any such proceeding, select and employ counsel (with
the approval of the Indemnified Party, not to be unreasonably withheld), and settle or prosecute
such proceeding to a final conclusion, and the Indemnified Party may participate in, but not
control, any such defense or settlement at its own cost and with its own counsel, and if requested
by the Indemnifying Party, the Indemnified Party agrees to cooperate with the Indemnifying Party
and its counsel in contesting any Claim that the Indemnifying Party elects to contest, or, if
appropriate and related to the Claim in question, in making any counterclaim against the Person
asserting the third-party Claim, or any cross-complaint against any Person. To the extent the
Indemnifying Party elects not to assume the defense of any Claim for which it has an indemnity
obligation under this Section 10.01, the Indemnified Party shall have the right to defend, and be
reimbursed for its reasonable cost and

38

 

expense incurred (but only if and to the extent the Indemnified Party is actually entitled to
indemnification hereunder) in regard to such Claim with counsel selected by the Indemnified Party
(who shall be reasonably satisfactory to the Indemnifying Party), by all appropriate proceedings.
In such circumstances, the Indemnified Party shall defend such Claim in good faith and have full
control of such defense and proceedings; provided, however, that the Indemnified Party may not
enter into any compromise or settlement of such Claim, if indemnification is to be sought
hereunder, without the Indemnifying Party’s consent. Additionally, in such circumstances, the
Indemnifying Party may participate in, but not control, any defense or settlement controlled by the
Indemnified Party pursuant to this Section 10.01(c), and the Indemnifying Party shall bear its own
costs and expenses with respect to such participation. Notwithstanding the foregoing, the
Indemnifying Party shall not, without the prior written consent of the Indemnified Party, effect
any settlement of any pending proceeding in respect of which any Indemnified Party is a party,
unless (A) such settlement includes a full and unconditional release of such Indemnified Party from
all liability on claims that are the subject matter of such proceeding, (B) such settlement does
not contain any admission of wrongdoing or illegal conduct and (C) the Indemnifying Party has
agreed in writing that it is liable to pay the full amount of the settlement to the extent
pertaining to such Indemnified Party.

     (d) If a Party becomes an Indemnified Party, it shall, at the Indemnifying Party’s expense,
cooperate with the Indemnifying Party and permit the Indemnifying Party reasonable access to the
Indemnified Party’s books, records, facilities and employees for the purpose of permitting the
Indemnifying Party to perform its obligations under this Section 10.01; provided, however, that the
Indemnified Party shall not be required to disclose to the Indemnifying Party any documents or
correspondence covered by the attorney-client privilege or the work product doctrine, except
pursuant to a joint defense agreement. To the extent that any documents or correspondence are
covered by the attorney-client privilege or the work product doctrine, the Indemnified Party shall
notify the Indemnifying Party if the Indemnified Party seeks to protect such privilege with respect
to third parties. The Indemnified Party shall disclose to the Indemnifying Party the
non-privileged contents of any such documents or correspondence. If requested by the Indemnifying
Party, the Indemnified Party and the Indemnifying Party shall negotiate in good faith a joint
defense agreement with respect to the matter that is the subject of the privileged communication or
work product.

     (e) With respect to the Indemnification Escrow Amount:

     (i) Any payment required to be made by Seller to any Buyer Indemnified Party pursuant
to Section 10.01(a) shall be first paid by release of all or a portion, as applicable, of
the Indemnification Escrow Amount pursuant to the terms of this Section and the
Indemnification Escrow Agreement, for so long as any portion of the Indemnification Escrow
Amount and/or any income thereon remains on deposit in the escrow account. The
Indemnification Escrow Amount shall only be released and distributed in accordance with
joint written instructions provided by Buyer and Seller to the Escrow Agent (“Joint
Instructions”) or a final and non-appealable decision rendered by a court of competent
jurisdiction (a “Final Order”). At any time and from time to time prior to the Final
Distribution Date, if any Buyer Indemnified Party claims in good faith that payment is due
from Seller pursuant to Seller’s indemnification obligations under Section 10.01(a), Buyer
shall give written notice of such claim to Seller and the

39

 

Escrow Agent (each an “Escrow Claim”) setting forth (A) the nature of and basis for the
Escrow Claim, and (B) the amount to which such Buyer Indemnified Party is entitled pursuant
to Section 10.01(a) (the “Escrow Claim Amount”) (to the extent the Escrow Claim Amount is
known and quantifiable as of such date and, if unknown, a good faith estimate assuming the
facts are true). Seller shall have thirty (30) days after receipt of the Escrow Claim to
dispute such Escrow Claim in writing delivered to Buyer and the Escrow Agent within such
30-day period (a “Dispute Notice”). If Seller does not give a Dispute Notice, then the
Escrow Claim Amount set forth in the Escrow Claim Notice shall be deemed conclusive for
purposes of this Agreement, and the Parties shall, on the first (1st) Business
Day after expiration of such 30-day period, provide Joint Instructions to the Escrow Agent
for release and distribution of such Escrow Claim Amount to Buyer from the Indemnification
Escrow Amount. If Seller gives a Dispute Notice, the Parties shall, on the first (1st)
Business Day after expiration of such 30-day period, provide Joint Instructions to the
Escrow Agent for release and distribution of any undisputed portion of the Escrow Claim
Amount to Buyer from the Indemnification Escrow Amount, but payment with respect to any
disputed Escrow Claim Amount (or portion thereof) shall only be made from the
Indemnification Escrow Amount in accordance with Joint Instructions or a Final Order to
enforce an award with respect to such Escrow Claim Amount.

     (ii) On the first (1st) Business Day after the date (the “First Distribution
Date”) that is three (3) months from the Closing Date, Buyer and Seller shall provide Joint
Instructions to the Escrow Agent detailing the amount and delivering instructions for a
release of a portion of the Indemnification Escrow Amount to Seller in an aggregate amount
equal to one-third (1/3rd) of the Indemnification Escrow Amount, minus (x) the
amounts for any Escrow Claims already satisfied by a distribution from the Indemnification
Escrow Amount, and (y) the amounts of any Unresolved Claims that are pending on the First
Distribution Date.

     (iii) On the first (1st) Business Day after the date (the “Second
Distribution Date”) that is six (6) months from the Closing Date, Buyer and Seller’ shall
provide Joint Instructions to the Escrow Agent detailing the amount and delivering
instructions for a release of a portion of the Indemnification Escrow Amount to Seller in an
aggregate amount equal to two-thirds (2/3rd) of the Indemnification Escrow
Amount, minus (x) the amounts for any Escrow Claims already satisfied by a distribution from
the Indemnification Escrow Amount, (y) the amounts of any Unresolved Claims that are pending
on the Second Distribution Date, and (z) all amounts previously distributed to Seller
pursuant to Section 10.01(e)(ii) above.

     (iv) On the first (1st) Business Day after the date (the “Final Distribution
Date”) that is twelve (12) months from the Closing Date, Buyer and Seller shall provide
Joint Instructions to the Escrow Agent detailing the amount and delivering instructions for
a release of the remaining portion of the Indemnification Escrow Amount to Seller; provided,
however, the Escrow Agent shall retain sufficient amounts for any Unresolved Claims that are
pending on the Final Distribution Date. Any income that accrues on the Indemnification
Escrow Amount shall be distributed to Seller as part of the final distribution from and
termination of the Indemnification Escrow Agreement, unless the

40

 

entire amount of the Indemnification Escrow Amount has been released to Buyer pursuant
to this Section 10.01(e), in which event (x) a portion of such income equal to that amount
necessary to satisfy any then remaining undisputed Escrow Claim Amounts or any award to
Buyer under a Final Order with respect to a disputed Escrow Claim Amount (which has not then
been paid) shall be released to Buyer and (y) the remaining portion of such income (if any)
shall be released to Seller.

     (v) “Unresolved Claim” shall mean, as of the First Distribution Date, the Second
Distribution Date or the Final Distribution Date, as the case may be, the aggregate amount
of all Escrow Claims that are the subject of a pending Dispute Notice or Escrow Claims which
have been delivered but for which Seller’s 30-day dispute period has not expired as of such
date.

     10.02 Exclusive Remedy Post-Closing. From and after Closing, Section 10.01 shall be the
exclusive remedy of both Parties for monetary Damages for breach of this Agreement and each of the
Parties hereby waives any other Claim, cause of action, or remedy for monetary Damages that it
might assert against the other, whether under statutory or common law, or any other Legal
Requirement; provided that nothing in this Section 10.02 shall prevent either Party from (i)
seeking specific performance, injunctive and/or similar equitable relief for claims of breach or
failure to perform covenants performable under this Agreement at any time after the Closing or (ii)
pursuing, and recovering in respect of, any claim based on actual fraud.

     10.03 Cooperation and Preservation of Books and Records. The Parties recognize that the
Parties and their respective Affiliates may need access, from time to time, after the Closing Date,
to certain accounting and Tax records and information held by the other Parties; therefore, the
Parties shall (a) use commercially reasonable efforts to properly retain and maintain such records
until the thirtieth (30th) day following the last date on which the period to which such
records relate is subject to audit by any Governmental Entity, and (b) subject to the right of each
Party to refrain from disclosing or making available any proprietary information, any written or
oral communications that are subject to the attorney-client privilege and any documents that are
covered by the work product doctrine, allow the requesting Party and its respective agents and
other representatives, at times and dates mutually acceptable to the Parties, to inspect, review,
and make copies of such records as the requesting Party may deem necessary or appropriate from time
to time for use in connection with the preparation of Tax Returns relating to the Purchased Assets
or in connection any lawsuit, Claim or Tax audit relating to the Purchased Assets. Such
inspection, review and copying of records shall be conducted during normal business hours and at
the requesting Party’s expense.

     10.04 Receipts and Expenses. (a) All monies, proceeds, receipts, credits and income
attributable to the Purchased Assets (including those received by Seller under the Excluded NAESB
Contracts with respect to the Purchased Assets) (“Receipts”) and attributable to the periods of
time from and after the Effective Time shall be the sole property and entitlement of Buyer, and, to
the extent received by Seller or any of its Affiliates, shall be promptly accounted for and
transmitted to Buyer, provided, however, any Receipts attributable to the period of time prior to
the end of the month during which Closing occurs may be utilized by Seller to pay Expenses
attributable to the period of time from the Effective Time through the end of the month in which
Closing occurs; and (b) all Receipts attributable to the period of time prior to the

41

 

Effective Time shall be the sole property and entitlement of Seller and, to the extent
received by Buyer, shall be promptly accounted for and transmitted to Seller. (c) All invoices,
direct costs, expenses, disbursements and payables attributable to the Purchased Assets (including
those incurred by Seller under the Excluded NAESB Contracts, the Excluded MSAs and the Management
Agreement with respect to the Purchased Assets and those incurred by Seller to acquire any New
Easements, but excluding the AFE Estimated Cost, the AFE Actual Cost, the Pipeline Inventory
Estimated Cost and the Pipeline Inventory Actual Cost and any Treating Cost Difference owed by
Buyer under Section 3.01) (“Expenses”), for all periods from and after the Effective Time shall be
the sole obligation of Buyer, and, to the extent any statements for same are received by Seller or
any of its Affiliates, shall be promptly transmitted to Buyer, and paid by Buyer, provided,
however, Seller may pay all such Expenses attributable to the period of time from the Effective
Time through the end of the month in which Closing occurs as permitted in Section 10.04(a) above;
and (d) all Expenses for all periods prior to the Effective Time shall, subject to Section 10.01,
be the sole obligation of Seller, and, to the extent any statements for same are received by Buyer
or any of its Affiliates, shall, subject to Section 10.01, be promptly transmitted to Seller, and
paid by Seller. All imbalances attributable to the Purchased Assets as of the time immediately
prior to the Effective Time shall be retained by Seller, and Seller shall be entitled to any
benefit on account thereof and shall be responsible for any obligations with respect thereto. All
imbalances attributable to the period of time from and after the Effective Time until Closing shall
be cashed out by Seller under its applicable balancing agreements, and all amounts received by
Seller under such cash-outs will be considered “Receipts” for purposes of this Section 10.04, and
all amounts paid by Seller under such cash-outs will be considered to be “Expenses” for purposes of
this Section 10.04.

     10.05 Ad Valorem and Property Taxes. All ad valorem taxes, real property taxes, personal
property taxes and similar obligations attributable to the Purchased Assets (“Property Taxes”)
relating to the tax period during which the Effective Time occurs shall be apportioned to the
Seller for the period up to and including the Effective Time and to the Buyer for the period after
the Effective Time on a ratable daily basis over the entire tax period based on the Property Taxes
assessed for the immediately preceding tax period. At Closing, the amount of Seller’s prorated
share of such Property Taxes shall be deducted from the Purchase Price, as full compensation for
Seller’s obligations with respect to all Property Taxes relating to the tax period during which the
Effective Time occurs. Buyer shall pay or cause to be paid, when due, to the taxing authorities
all Property Taxes relating to the tax period during which the Effective Time occurs.

     10.06 Transfer Taxes. Buyer and Seller shall each be responsible for one-half of all Transfer
Taxes required to be paid in connection with the sale of the Purchased Assets pursuant to this
Agreement.

     10.07 Investigation of Books and Records. Buyer’s closing of the transaction contemplated
hereby will constitute Buyer’s acknowledgment that it has had, prior to the Closing Date, access to
the Purchased Assets, the Records, and the officers and employees of Seller to its full and
complete satisfaction. Buyer hereby further acknowledges that in making the decision to enter into
this Agreement and consummate the transactions contemplated hereby, it is relying solely on its own
independent investigation and due diligence and the express representations, warranties, covenants
and agreements of Seller set forth in this Agreement. Except for such

42

 

express representations and warranties, Seller makes no representation or warranty of any kind
as to the Records, any information contained therein or any other information provided to Buyer by
or on behalf of Seller. Buyer agrees that any conclusions drawn from the Records and such
information are and shall be the result of its own independent review and judgment.

     10.08 Removal of Decals, Logos and Signs; Emergency Contact Numbers. As soon as practicable
after the Closing Date, but in no event later than ninety (90) days thereafter, Buyer shall cease
to use and shall remove or cause to be removed the names and marks used by Seller and its
Affiliates and all variations and derivatives thereof and logos relating thereto from the Purchased
Assets and shall not thereafter make any use whatsoever of such names, marks, and logos whether as
identification for the Purchased Assets or in connection with documentation and correspondence
relating thereto, except as may be necessary to complete the transfer of the Purchased Assets and
any consents related thereto.

     10.09 Transition Services. In order to facilitate the transition of Buyer as the owner of the
Purchased Assets, the Parties shall enter into a Transition Services Agreement, in the form
attached hereto as Exhibit I (the “Transition Services Agreement”), for a period commencing
on the Closing Date and ending on the date on which the Transition Service Agreement is terminated
in accordance with its provisions. Pursuant to the Transition Services Agreement, Seller shall
provide or cause to be provided to Buyer certain support services specified therein.

     10.10 Suspended Funds. The Parties acknowledge that Seller has suspended payment of certain
funds in accordance with a Contract (the “Suspended Funds”) as further described in Schedule
10.10. Seller shall transfer the Suspended Funds to Buyer at Closing, and, notwithstanding
anything to the contrary contained herein, including, but not limited to, Section 2.01(d), Buyer
shall thereafter be fully responsible and liable for payment of such Suspended Funds to the
appropriate Persons owed such funds, and such responsibility and liability shall be deemed to be
Assumed Liabilities.

     10.11 Bulk Transfer Laws. Buyer hereby waives compliance by Seller with the provisions of any
so called bulk transfer laws of any jurisdiction in connection with the purchase and sale of the
Purchased Assets; provided however, that in accordance with Article 10 hereof, Seller shall
indemnify and hold Buyer harmless from any Damages which Buyer may incur due to failure to comply
with such laws.

     10.12 Limitation of Liability.

     (a) IN NO EVENT SHALL ANY PARTY HERETO BE LIABLE HEREUNDER FOR EXEMPLARY, PUNITIVE, INDIRECT,
SPECIAL INCIDENTAL OR CONSEQUENTIAL DAMAGES, OR LOST PROFITS OF ANY KIND, ARISING DIRECTLY OR
INDIRECTLY FROM, INCIDENT TO, OR IN ANY WAY CONNECTED WITH THIS AGREEMENT, REGARDLESS OF SOLE OR
CONCURRENT NEGLIGENCE, STRICT LIABILITY, OR DEFECT IN PREMISES, EQUIPMENT OR MATERIAL, AND
REGARDLESS OF WHETHER PRE-EXISTING THIS AGREEMENT. This Section shall in no way limit or qualify
the Parties’ indemnification obligations under Section 10.01 with respect to Claims made against
any Party by a non-Affiliate third Person.

43

 

     (b) SELLER SHALL NOT HAVE ANY RIGHTS OR CLAIMS AGAINST ANY LENDING SOURCE IN CONNECTION WITH
THIS AGREEMENT OR ANY OF THE DOCUMENTS RELATED TO THE TRANSACTION FINANCING, WHETHER AT LAW OR IN
EQUITY, IN CONTRACT, IN TORT OR OTHERWISE.

     10.13 Disclaimers. Buyer acknowledges that, except as expressly set forth herein, (a) SELLER
HAS NOT MADE AND BY THE DOCUMENTS OF CONVEYANCE AND TRANSFER TO BE EXECUTED PURSUANT HERETO SHALL
NOT BE DEEMED TO HAVE MADE, AND (b) SELLER HEREBY EXPRESSLY DISCLAIMS AND NEGATES, ANY
REPRESENTATION OR WARRANTY OF ANY KIND WHATSOEVER, EXPRESS OR IMPLIED, INCLUDING (i) ANY IMPLIED
REPRESENTATION OR WARRANTY AS TO THE CONDITION, MERCHANTABILITY, USAGE, NON-INFRINGEMENT,
SUITABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE AND (ii) ANY REPRESENTATION OR WARRANTY AS TO (1)
CONTRACTUAL, ECONOMIC OR FINANCIAL INFORMATION ASSOCIATED WITH THE PURCHASED ASSETS, (2) ANY
PROJECTIONS, FORECASTS, BUSINESS PLANS OR BUDGET INFORMATION, (3) THE CONTINUED FINANCIAL VIABILITY
OR PRODUCTIVITY OF THE PURCHASED ASSETS, (4) THE ENVIRONMENTAL OR PHYSICAL CONDITION OF THE
PURCHASED ASSETS, OR (5) TITLE TO THE PURCHASED ASSETS. EXCEPT AS OTHERWISE EXPRESSLY PROVIDED
HEREIN, BUYER IS ACQUIRING THE PURCHASED ASSETS IN “AS-IS, WHERE-IS” PHYSICAL CONDITION, WITH ALL
FAULTS, BOTH PATENT AND LATENT, REGARDLESS OF HOW SUCH FAULTS WERE CAUSED OR CREATED (BY SELLER’S
NEGLIGENCE OR OTHERWISE).

     10.14 Non-Competition. To assure that Buyer will realize the benefits of the transactions
contemplated hereunder, Seller hereby agrees not to:

     (a) For a period of one (1) year after the Closing Date, directly or indirectly, alone or as a
shareholder, partner, joint venturer, officer, director, member, manager, employee, consultant,
agent, independent contractor or equity interest holder of, or lender to, any Person, entity or
business, engage in any business or activities the same as or similar to the business of operating
the Purchased Assets within Roberts County, Texas and each of Van Buren, Conway, Faulkner and White
Counties, Arkansas.

     (b) For a period of one (1) year after the Closing Date, directly or indirectly, solicit for
employment any employees of Buyer; provided that, the foregoing shall not prohibit Seller from
offering to employ or employing any such employees of Buyer who respond to a general employment
advertisement not directed at Buyer or Buyer’s employees.

Notwithstanding the foregoing, the beneficial ownership of less than 1% of the equity interests of
any Person having a class of equity interests actively traded on a national securities exchange or
over-the-counter market shall not be deemed, in and of itself, to breach the prohibitions of this
Section 10.14.

notwithstanding the foregoing each Class C Unit shall be deemed a Common Unit (whether
converted or not) with respect to any voting, approval or consent rights conferred upon
Common Units in this Agreement including pursuant to Sections 4.7, 7.9(a), 11.1(b), 11.2,

of which such Class C Unit is issued.

     “Remaining Net Positive Adjustments” means as of the end of any taxable period, (i)
with respect to the Unitholders holding Common Units, Subordinated Units, Class B Units or
Class C Units, the excess of (a) the Net Positive Adjustments of the Unitholders holding
Common Units, Subordinated Units, Class B Units or Class C Units as of the end of such
period over (b) the sum of those Partners’ Share of Additional Book Basis

3

 

Derivative Items for each prior taxable period, (ii) with respect to the General

Basis Derivative Items as the Remaining Net Positive Adjustments of the Partners holding the
Incentive Distribution Rights as of the end of such period bears to the Aggregate Remaining
Net Positive Adjustments as of that time.

     “Subordinated Unit” means a Partnership Security representing a fractional part of the
Partnership Interests of all Limited Partners and Assignees and having the rights and
obligations specified with respect to Subordinated Units in this Agreement. The term

Subordinated Unit that is convertible into a Common Unit shall not constitute a Common Unit
until such conversion occurs.

     “Unit” means a Partnership Security that is designated as a “Unit” and shall include

     Section 4.1 Certificate

     Upon the Partnership’s issuance of Common Units, Subordinated Units, Class B Units or
Class C Units to any Person, the Partnership shall issue, upon the request of such Person,
one or more Certificates in the name of such Person evidencing the number of such Units
being so issued. In addition, (a) upon the General Partner’s request, the Partnership shall
issue to it one or more Certificates in the name of the General Partner evidencing its
General Partner Units and (b) upon the request of any Person owning Incentive Distribution
Rights or any other Partnership Securities other than Common Units, Subordinated Units,
Class B Units or Class C Units, the Partnership shall issue to such Person one or more
certificates evidencing such Incentive Distribution Rights or other Partnership Securities
other than Common Units, Subordinated Units, Class B Units or Class C Units. Certificates
shall be executed on behalf of the Partnership by the Chairman of the Board, President or
any Executive Vice President, Senior Vice President or Vice President and the Secretary or
any Assistant Secretary of the General Partner. No Common Unit Certificate shall be valid
for any purpose until it has been countersigned by the Transfer Agent; provided, however,
that the Units may be certificated or uncertificated as provided in the Delaware Act; and
provided, further, that if the General Partner elects to issue Common Units in global form,
the Common Unit Certificates shall be valid upon receipt of a certificate from the Transfer
Agent certifying that the Common Units have been duly registered in accordance with the
directions of the Partnership. Subject to the requirements of Section 6.7(c), the Partners
holding Certificates evidencing Subordinated Units may exchange such Certificates for
Certificates evidencing Common Units on or after the date on which such Subordinated Units
are converted into Common Units pursuant to the terms of Section 5.7. Subject to the
requirements of Section 6.7(e), the Partners holding Certificates evidencing Class B Units
may exchange such Certificates for Certificates evidencing Common Units on or after the
period set forth in Section 5.11(f) pursuant to the terms of Section 5.11. The Partners
holding Certificates evidencing Class C Units may exchange such Certificates for
Certificates evidencing Common Units on or after the date on which such Class C Units are
converted into Common Units pursuant to the terms of Section 5.12.

     3. Section 4.5(d) of the Partnership Agreement is hereby amended and restated as follows:

     (d) The General Partner and its Affiliates shall have the right at any time to transfer
their Subordinated Units, Class B Units, Class C Units and Common Units

5

 

(whether issued upon conversion of the Subordinated Units, conversion of Class C Units or
otherwise) to one or more Persons.

     4. Section 5.5(a) of the Partnership Agreement is hereby amended and restated as follows:

     (a) The Partnership shall maintain for each Partner (or a beneficial owner of
Partnership Interests held by a nominee in any case in which the nominee has furnished the
identity of such owner to the Partnership in accordance with Section 6031(c) of the Code or
any other method acceptable to the General Partner) owning a Partnership Interest a separate
Capital Account with respect to such Partnership Interest in accordance with the rules of
Treasury Regulation Section 1.704-1(b)(2)(iv). Such Capital Account shall be increased by
(i) the amount of all Capital Contributions made to the Partnership with respect to such
Partnership Interest and (ii) all items of Partnership income and gain (including income and
gain exempt from tax) computed in accordance with Section 5.5(b) and allocated with respect
to such Partnership Interest pursuant to Section 6.1, and decreased by (x) the amount of
cash or Net Agreed Value of all actual and deemed distributions of cash or property
(provided that PIK Units shall not be deemed property for these purposes) made with respect
to such Partnership Interest and (y) all items of Partnership deduction and loss computed in
accordance with Section 5.5(b) and allocated with respect to such Partnership Interest
pursuant to Section 6.1. The initial Capital Account balance in respect of each Class C
Unit (other than PIK Units) shall be determined by reference to the fair market value of a
Common Unit on the date such Unit is issued as set forth in the Unit Purchase Agreement or
Registration Rights Agreement, as applicable. The initial Capital Account balance in
respect of each PIK Unit shall be determined in accordance with Section 5.12(d)(iv).
Immediately following the initial creation of a Capital Account balance in respect of each
Class C Unit, each Unitholder acquiring such a Unit at original issuance shall be deemed to
have received a cash distribution or to have made a cash contribution, as the case may be,
in respect of such Unit equal to the amount by which (A) the fair market value of a Common
Unit on the date of issuance exceeds or is less than, as the case may be, (B) the Issue
Price for such Unit.

     5. Section 5.5(c) of the Partnership Agreement is hereby amended to add a new subclause (iii)
as follows:

     (iii) Immediately prior to the transfer of a Class C Unit or of a Class C Unit that has
converted into a Common Unit pursuant to Section 5.12 by a holder thereof (other than a
transfer to an Affiliate unless the General Partner elects to have this subparagraph
5.5(c)(iii) apply), the Capital Account maintained for such Person with respect to its Class
C Units or converted Class C Units will (A) first, be allocated to the Class C Units or
converted Class C Units to be transferred in an amount equal to the product of (x) the
number of such Class C Units or converted Class C Units to be transferred and (y) the Per
Unit Capital Amount for a Common Unit, and (B) second, any remaining balance in such Capital
Account will be retained by the transferor, regardless of whether it has retained any Class
C Units or converted Class C Units (“Retained Converted Class C Units”); provided that, if
such remaining balance would be negative,

6

 

items of Partnership income and gain shall be specially allocated pursuant to Section
6.1(d)(v) to such transferor Partner in an amount and manner sufficient to eliminate the
deficit in its Capital Account as quickly as possible. Following any such allocation, the
transferor’s Capital Account, if any, maintained with respect to the retained Class C Units
or Retained Converted Class C Units, if any, will have a balance equal to the amount
allocated under clause (B) hereinabove, and the transferee’s Capital Account established
with respect to the transferred Class C Units or converted Class C Units will have a balance
equal to the amount allocated under clause (A) hereinabove.

     6. Section 5.5(d) of the Partnership Agreement is hereby amended and restated as follows:

     (d) (i) In accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(f), on an
issuance of additional Partnership Interests for cash or Contributed Property, the issuance
of Partnership Interests as consideration for the provision of services, the conversion of
the General Partner’s Combined Interest to Common Units pursuant to Section 11.3(b), or the
conversion of Class C Units to Common Units pursuant to Section 5.12(c), the Capital
Accounts of all Partners and the Carrying Value of each Partnership property immediately
prior to such issuance or conversion shall be adjusted upward or downward to reflect any
Unrealized Gain or Unrealized Loss attributable to such Partnership property, as if such
Unrealized Gain or Unrealized Loss had been recognized on an actual sale of each such
property immediately prior to such issuance and had been allocated to the Partners at such
time (x) first, if such issuance or conversion occurs after the initial issuance of Class C
Units, in a manner that to the nearest extent possible results in the Capital Accounts
maintained with respect to the Class C Units and the converted Class C Units on a per unit
basis equaling the Per Unit Capital Amount for a Common Unit (other than a Common Unit
issued upon the conversion of a Subordinated Unit, a Class B Unit or a Class C Unit) and (y)
second, pursuant to Section 6.1(c) in the same manner as any item of gain or loss actually
recognized during such period would have been allocated. In determining such Unrealized
Gain or Unrealized Loss, the aggregate cash amount and fair market value of all Partnership
assets (including cash or cash equivalents) immediately prior to the issuance of additional
Partnership Interests, or immediately after the conversion, shall be determined by the
General Partner using such method of valuation as it may adopt; provided, however, that the
General Partner, in arriving at such valuation, must take fully into account the fair market
value of the Partnership Interests of all Partners at such time. The General Partner shall
allocate such aggregate value among the assets of the Partnership (in such manner as it
determines) to arrive at a fair market value for individual properties.

          (ii) In accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(f), immediately
prior to any actual or deemed distribution to a Partner of any Partnership property (other
than a distribution of cash that is not in redemption or retirement of a Partnership
Interest), the Capital Accounts of all Partners and the Carrying Value of all Partnership
property shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized
Loss attributable to such Partnership property, as if such Unrealized Gain or Unrealized
Loss had been recognized in a sale of such property immediately

7

 

prior to such distribution for an amount equal to its fair market value, and had been
allocated to the Partners at such time (x) first, if such actual or deemed distribution
occurs after the initial issuance of Class C Units, in a manner that to the nearest extent
possible results in the Capital Accounts maintained with respect to the Class C Units and
the converted Class C Units on a per unit basis equaling the Per Unit Capital Amount for a
Common Unit (other than a Common Unit issued upon the conversion of a Subordinated Unit, a
Class B Unit or a Class C Unit) and (y) second, pursuant to Section 6.1(c) in the same
manner as any item of gain or loss actually recognized during such period would have been
allocated. In determining such Unrealized Gain or Unrealized Loss the aggregate cash amount
and fair market value of all Partnership assets (including cash or cash equivalents)
immediately prior to a distribution shall (A) in the case of an actual distribution that is
not made pursuant to Section 12.4 or in the case of a deemed distribution, be determined and
allocated in the same manner as that provided in Section 5.5(d)(i) or (B) in the case of a
liquidating distribution pursuant to Section 12.4, be determined and allocated by the
Liquidator using such method of valuation as it may adopt.

     7. Section 5.9 of the Partnership Agreement is hereby amended to add a new clause (e) as
follows:

     (e) For the avoidance of doubt, upon any pro rata distribution of Partnership
Securities to all Record Holders of Common Units or any subdivision or combination (or
reclassified into a greater or smaller number) of Common Units, the Partnership will
proportionately adjust the number of Class C Units as follows: (i) if the Partnership issues
Partnership Securities as a distribution on its Common Units or subdivides the Common Units
(or reclassifies them into a greater number of Common Units) then the Class C Units shall be
subdivided into a number of Class C Units equal to the result of multiplying the number of
Class C Units by a fraction, (A) the numerator of which shall be the sum of the number of
Common Units outstanding immediately prior to such distribution or subdivision plus the
total number of Partnership Securities constituting such distribution or newly created by
such subdivision; and (B) the denominator of which shall be the number of Common Units
outstanding immediately prior to such distribution or subdivision; and (ii) if the
Partnership combines the Common Units (or reclassifies them into a smaller number of Common
Units) then the Class C Units shall be combined into a number of Class C Units equal to the
result of multiplying the number of Class C Units by a fraction, (A) the numerator of which
shall be the sum of the number of Common Units outstanding immediately following such
combination; and (B) the denominator of which shall be the number of Common Units
outstanding immediately prior to such combination.

     8. Article V of the Partnership Agreement is hereby amended to add a new Section 5.12 creating

     Section 5.12 Establishment of Class C Units

     (a) The General Partner hereby designates and creates a series of Limited Partner
Interests to be designated as “Class C Units” and consisting of a total of [__________]
Class C Units, having the terms and conditions set forth herein.

     (b) The holders of the Class C Units shall have rights upon dissolution and liquidation
of the Partnership, including the right to share in any liquidating distributions pursuant
to Section 12.4, in accordance with Article XII of this Agreement.

     (c) Conversion of Class C Units

     (i) Immediately before the close of business on the Conversion Date, the Class
C Units shall automatically convert into Common Units on a one-for-one basis.

     (ii) Upon conversion, the rights of a holder of converted Class C Units as
holder of Class C Units shall cease with respect to such converted Class C Units,
including any rights under this Agreement with respect to holders of Class C Units,
and such Person shall continue to be a Limited Partner and have the rights of a
holder of Common Units under this Agreement. All Class C Units shall, upon the
Conversion Date, be deemed to be transferred to, and cancelled by, the Partnership
in exchange for the Common Units into which the Class C Units converted.

     (iii) The Partnership shall pay any documentary, stamp or similar issue or
transfer taxes or duties relating to the issuance or delivery of Common Units upon
conversion of the Class C Units. However, the holder shall pay any tax or duty
which may be payable relating to any transfer involving the issuance or delivery of
Common Units in a name other than the holder’s name. The Transfer Agent may refuse
to deliver a Certificate representing Common Units being issued in a name other than
the holder’s name until the Transfer Agent receives a sum sufficient to pay any tax
or duties which will be due because the shares are to be issued in a name other than
the holder’s name. Nothing herein shall preclude any tax withholding required by
law or regulation.

     (iv) (A) Except as otherwise provided in Section 5.8, the Partnership shall
keep free from preemptive rights a sufficient number of Common Units to permit the
conversion of all outstanding Class C Units into Common Units to the extent provided
in, and in accordance with, this Section 5.12(c).

          (B) All Common Units delivered upon conversion of the Class C Units shall be
newly issued, shall be duly authorized and validly issued, and shall be free from
preemptive rights (except as otherwise provided in Section 5.8) and free of any lien
or adverse claim.

          (C) The Partnership shall comply with all applicable securities laws
regulating the offer and delivery of any Common Units upon conversion of

9

 

Class C Units and, if the Common Units are then listed or quoted on the New York
Stock Exchange, or any other National Securities Exchange or other market, shall
list or cause to have quoted and keep listed and quoted the Common Units issuable
upon conversion of the Class C Units to the extent permitted or required by the
rules of such exchange or market.

          (D) Notwithstanding anything herein to the contrary, nothing herein shall give
to any holder of Class C Units any rights as a creditor in respect of its right to
conversion.

(d) Class C Distributions.

     (i) Each Class C Unit shall have the right to share in distributions pursuant
to Sections 6.4(a)(i), 6.4(a)(ii), 6.4(a)(iv), 6.4(a)(v), 6.4(a)(vi), 6.4(a)(vii),
6.4(b)(i), 6.4(b)(ii), 6.4(b)(iii), 6.4(b)(iv), 6.4(b)(v) and 6.5 on a pro rata
basis with the Common Units as provided therein. All or any portion of each
distribution payable in respect of the Class C Units (the “Class C Unit
Distribution”) may, at the election of the Partnership, be paid in Class C Units
(any amount of such Class C Unit Distribution so paid in PIK Units, the “PIK
Distribution Amount”). The number of PIK Units to be issued in connection with a
PIK Distribution Amount shall be the quotient of (A) the PIK Distribution Amount
divided by (B) the volume-weighted average price of the Partnership’s Common Units
for the ten (10) trading days immediately preceding the date the Class C Unit
Distribution is declared; provided that instead of issuing any fractional PIK Units,
the Partnership shall round the number of PIK Units issued down to the next lower
whole PIK Unit and pay cash in lieu of such fractional units, or at the
Partnership’s option, the Partnership may round the number of PIK Units issued up to
the next higher whole PIK Unit.

     (ii) Notwithstanding anything in this Section 5.12(d) to the contrary, with
respect to Class C Units that are converted into Common Units, the holder thereof
shall not be entitled to a Class C Unit Distribution and a Common Unit distribution
with respect to the same period, but shall be entitled only to the distribution to
be paid based upon the class of Units held as of the close of business on the
applicable Record Date.

     (iii) When any PIK Units are payable to a holder of Class C Units pursuant to
this Section 5.12, the Partnership shall issue the PIK Units to such holder no later
than the date the corresponding distributions are made pursuant to Section 6.4 or
6.5, as applicable (the date of issuance of such PIK Units, the “PIK Payment Date”).
On the PIK Payment Date, the Partnership shall issue to such holder of Class C
Units a certificate or certificates for the number of PIK Units to which such holder
of Class C Units shall be entitled.

     (iv) For purposes of maintaining Capital Accounts under Section 5.5, if the
Partnership distributes one or more PIK Units to a holder of Class C Units or to a
holder of Incentive Distribution Rights, (i) the Partnership shall be treated as

10

 

distributing cash to such holder of Class C Units or Incentive Distribution Rights
equal to the PIK Distribution Amount or PIK IDR Distribution Amount, as applicable,
and (ii) the holder of Class C Units or Incentive Distribution Rights shall be
deemed to have recontributed to the Partnership in exchange for such newly issued
PIK Units an amount of cash equal to the PIK Distribution Amount or PIK IDR
Distribution Amount, as applicable, less the amount of any cash distributed by the
Partnership in lieu of fractional PIK Units.

     (v) To the extent any portion of the Class C Unit Distribution is paid in PIK
Units for any Quarter pursuant to Section 5.12(d)(i), a portion of the Incentive
Distributions for such Quarter shall likewise be paid to the holders of Incentive
Distribution Rights in PIK Units (any amount of such Incentive Distributions so paid
in PIK Units, the “PIK IDR Distribution Amount”). The PIK IDR Distribution Amount
for any such Quarter shall be equal to the product of the aggregate Incentive
Distributions distributable to the holders of Incentive Distribution Rights
(including any PIK IDR Distribution Amount) for such Quarter, multiplied by the
quotient of (1) the PIK Distribution Amount for such Quarter divided by (2) the
aggregate distributions distributable (including any PIK Distribution Amount) with
respect to all Units for such Quarter pursuant to Sections to Sections 6.4 and 6.5.
The number of PIK Units to be issued in connection with a PIK IDR Distribution
Amount shall be the quotient of (A) the PIK IDR Distribution Amount divided by (B)
the volume-weighted average price of the Partnership’s Common Units for the ten (10)
trading days immediately preceding the date the relevant Class C Unit Distribution
is declared; provided that instead of issuing any fractional PIK Units, the
Partnership shall round the number of PIK Units issued down to the next lower whole
PIK Unit and pay cash in lieu of such fractional units, or at the Partnership’s
option, the Partnership may round the number of PIK Units issued up to the next
higher whole PIK Unit.

     (e) The Class C Units will have such voting rights pursuant to this Agreement as such
Class C Units would have if they were Common Units that were then outstanding and shall vote
together with the Common Units as a single class, except that the Class C Units shall be
entitled to vote as a separate class on any matter on which Unitholders are entitled to vote
that adversely affects the rights or preferences of the Class C Units in relation to other
classes of Partnership Interests in any material respect or as required by law. The
approval of a majority (or such other percentage as set forth in this Agreement) of the
Class C Units shall be required to approve any matter for which the holders of the Class C
Units are entitled to vote as a separate class.

     (f) Each Class C Unit and each Class C Unit that has converted into a Common Unit shall
be subject to the provisions of Sections 5.5(c)(iii), 5.5(d), 6.1(d)(x)(C) and 6.7(f).

11

 

     9. Section 6.1(c)(i)(C) of the Partnership Agreement is hereby amended and restated as
follows:

     (C) Third, (x) to the extent the Adjusted Capital Account of a Common Unit or
comparable fraction thereof and a Class C Unit (or converted Class C Unit) or comparable
fraction thereof are not identical, (1) to all Unitholders holding such class of Units with
the lower Adjusted Capital Account, proportionately, a percentage equal to 100% less the
percentage applicable to subclause (2) of this subclause (x) of this Clause (C) and (2) to
the General Partner in accordance with its Percentage Interest, until the Adjusted Capital
Account of each Common Unit or comparable fraction thereof and each Class C Unit (or
converted Class C Unit) or comparable fraction thereof are equal, and (y) if after
application of subclause (x) of this Clause (C), the Adjusted Capital Account of a Common
Unit or comparable fraction thereof and a Class C Unit or comparable fraction thereof, on
the one hand, and a Class B Unit (or converted Class B Unit) or comparable fraction thereof,
on the other hand, are not identical, (1) to all Unitholders holding the class (or classes)
of Units with the lower Adjusted Capital Account, proportionately, a percentage equal to
100% less the percentage applicable to subclause (2) of this subclause (y) of this Clause
(C) and (2) to the General Partner in accordance with its Percentage Interest, until the
Adjusted Capital Accounts of all of such Unitholders in such Units (on a per Unit basis) are
equal;

     10. Section 6.1(c)(ii)(B) of the Partnership Agreement is hereby amended and restated as
follows:

     (B) Second, (x) if the Adjusted Capital Account of a Common Unit or comparable fraction
thereof, a Class C Unit (or converted Class C Unit) or comparable fraction thereof and a
Class B Unit (or converted Class B Unit) or comparable fraction thereof are not identical,
(1) to the Unitholders holding the class of Units with the highest Adjusted Capital Account,
proportionately, a percentage equal to 100% less the percentage applicable to subclause (2)
of this subclause (x) of this Clause (B) and (2) to the General Partner, in accordance with
its Percentage Interest, until the Adjusted Capital Account of such Unitholders (on a per
Unit basis) is equal to the Adjusted Capital Account of the Unitholders holding the class of
Units with the next highest Adjusted Capital Account (on a per Unit basis) and (y) if after
application of subclause (x) of this Clause (B), the Adjusted Capital Account of a Common
Unit or comparable fraction thereof, a Class C Unit (or converted Class C Unit) or
comparable fraction thereof and a Class B Unit (or converted Class B Unit) or comparable
fraction thereof are not identical, (1) to the Unitholders holding the class(es) of Units
with the higher Adjusted Capital Account, proportionately, a percentage equal to 100% less
the percentage applicable to subclause (2) of this subclause (y) of this Clause (B), and (2)
to the General Partner, in accordance with its Percentage Interest, until the Adjusted
Capital Account of each Common Unit or comparable fraction thereof, each Class C Unit (or
converted Class C Unit) or comparable fraction thereof and each Class B Unit (or converted
Class B Unit) or comparable fraction thereof are equal;

12

 

     11. Section 6.1(d)(x) of the Partnership Agreement is hereby amended and restated as follows:

     (x) Economic Uniformity.

     (A) At the election of the General Partner with respect to any taxable period ending
upon, or after, the termination of the Subordination Period, all or a portion of the
remaining items of Partnership gross income or gain for such taxable period, after taking
into account allocations pursuant to Section 6.1(d)(iii), shall be allocated 100% to each
Partner holding Subordinated Units that are Outstanding as of the termination of the
Subordination Period (“Final Subordinated Units”) in the proportion of the number of Final
Subordinated Units held by such Partner to the total number of Final Subordinated Units then
Outstanding, until each such Partner has been allocated an amount of income or gain that
increases the Capital Account maintained with respect to such Final Subordinated Units to an
amount equal to the product of (A) the number of Final Subordinated Units held by such
Partner and (B) the Per Unit Capital Amount for a Common Unit (other than a Common Unit
issued upon the conversion of a Subordinated Unit, a Class B Unit or a Class C Unit). The
purpose of this allocation is to establish uniformity between the Capital Accounts
underlying Final Subordinated Units and the Capital Accounts underlying most or all of the
Common Units held by Persons other than the General Partner and its Affiliates immediately
prior to the conversion of such Final Subordinated Units into Common Units. This allocation
method for establishing such economic uniformity will be available to the General Partner
only if the method for allocating the Capital Account maintained with respect to the
Subordinated Units between the transferred and retained Subordinated Units pursuant to
Section 5.5(c)(ii) does not otherwise provide such economic uniformity to the Final
Subordinated Units.

     (B) At the election of the General Partner with respect to any taxable period ending
upon, or after, the conversion of the Class B Units pursuant to Section 5.11(f), all or a
portion of the remaining items of Partnership gross income or gain for such taxable period,
after taking into account allocations pursuant to Section 6.1(d)(iii) and Section
6.1(d)(x)(A), shall be allocated 100% to the holder or holders of the Common Units resulting
from the conversion pursuant to Section 5.11(f) (“Converted Common Units”) in the proportion
of the number of the Converted Common Units held by such holder or holders to the total
number of Converted Common Units then Outstanding, until each such holder has been allocated
an amount of income or gain that increases the Capital Account maintained with respect to
such Converted Common Units to an amount equal to the product of (A) the number of Converted
Common Units held by such holder and (B) the Per Unit Capital Amount for a Common Unit
(other than a Common Unit issued upon the conversion of a Subordinated Unit, a Class B Unit
or a Class C Unit). The purpose of this allocation is to establish uniformity between the
Capital Accounts underlying Converted Common Units and the Capital Accounts underlying most
or all of the Common Units held by Persons other than the General Partner and its Affiliates
immediately prior to the receipt of Common Units pursuant to Section 5.11(f)

     (C) At the election of the General Partner with respect to any taxable period ending
upon, or after, the conversion of the Class C Units into Common Units pursuant to

13

 

Section 5.12, all or a portion of the remaining items of Partnership gross income or
gain for such taxable period, after taking into account allocations pursuant to Section
6.1(d)(iii), shall be allocated 100% to the holder or holders of the Common Units resulting
from the conversion of Class C Units pursuant to Section 5.12 (“Converted Class C Units”) in
the proportion of the number of the Converted Class C Units held by such holder or holders
to the total number of Converted Class C Units then Outstanding, until each such holder has
been allocated an amount of income or gain that increases the Capital Account maintained
with respect to such Converted Class C Units to an amount equal to the product of (A) the
number of Converted Class C Units held by such holder and (B) the Per Unit Capital Amount
for a Common Unit (other than a Common Unit issued upon the conversion of a Subordinated
Unit, a Class B Unit or a Class C Unit). The purpose of this allocation is to establish
uniformity between the Capital Accounts underlying Converted Class C Units and the Capital
Accounts underlying most or all of the Common Units held by Persons other than the General
Partner and its Affiliates immediately prior to the conversion of Class C Units into Common
Units. The General Partner shall have discretion as to the priority of the application of
this Section 6.1(d)(x)(C) as compared to Sections 6.1(d)(x)(A) and 6.1(d)(x)(B).

     12. Section 6.4(a)(i) of the Partnership Agreement is hereby amended and restated as follows:

     (i) First, (x) to the General Partner in accordance with its Percentage Interest and
(y) to the Unitholders holding Common Units and Class C Units, Pro Rata, a percentage equal
to 100% less the General Partner’s Percentage Interest, until there has been distributed in
respect of each Common Unit then Outstanding an amount equal to the Minimum Quarterly
Distribution for such Quarter;

     13. Section 6.4(a)(ii) of the Partnership Agreement is hereby amended and restated as follows:

     (ii) Second, (x) to the General Partner in accordance with its Percentage
Interest and (y) to the Unitholders holding Common Units and Class C Units, Pro Rata, a
percentage equal to 100% less the General Partner’s Percentage Interest, until there has
been distributed in respect of each Common Unit then Outstanding an amount equal to the
Cumulative Common Unit Arrearage existing with respect to such Quarter;

     14. Section 6.5 of the Partnership Agreement is hereby amended and restated as follows:

     Section 6.5 Distributions of Available Cash from Capital Surplus

     Available Cash that is deemed to be Capital Surplus pursuant to the provisions of
Section 6.3(a) shall, subject to Section 17-607 of the Delaware Act, be distributed, unless
the provisions of Section 6.3 require otherwise, 100% to the General Partner and the
Unitholders in accordance with their respective Percentage Interests, until a hypothetical
holder of a Common Unit acquired on the Closing Date has received with respect to such
Common Unit, during the period since the Closing Date through such date, distributions

14

 

of Available Cash that are deemed to be Capital Surplus in an aggregate amount equal to
the Initial Unit Price. Available Cash that is deemed to be Capital Surplus shall then be
distributed (A) to the General Partner in accordance with its Percentage Interest and (B) to
all Unitholders holding Common Units and Class C Units, Pro Rata, a percentage equal to 100%
less the General Partner’s Percentage Interest, until there has been distributed in respect
of each Common Unit then Outstanding an amount equal to the Cumulative Common Unit
Arrearage. Thereafter, all Available Cash shall be distributed as if it were Operating
Surplus and shall be distributed in accordance with Section 6.4.

     15. The heading to Section 6.7 of the Partnership Agreement is hereby amended to read in its
entirety: Special Provisions Relating to the Holders of Subordinated Units, Class B Units and Class
C Units.

     16. Section 6.7 of the Partnership Agreement is hereby amended to add a new clause (f) as
follows:

     (f) The holder of a Class C Unit shall have all of the rights and obligations of a
Unitholder holding Common Units hereunder; provided, however, that such Class C Units shall
be and after conversion into Common Units pursuant to Section 5.12 shall remain subject to
the provisions of Sections 5.5(c)(iii) and 6.1(d)(x)(C).

     17. Except as hereby expressly modified, all terms of the Partnership Agreement remain in full
force and effect. This Amendment (i) shall bind and benefit the partners and their respective
heirs, beneficiaries, administrators, executors, receivers, trustees, successors, and assigns; (ii)
shall be modified or amended only in the manner set forth in the Partnership Agreement; (iii) SHALL
BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE AND THE UNITED
STATES OF AMERICA FROM TIME TO TIME IN EFFECT; (iv) and embodies the entire agreement and
understanding between the parties with respect to modifications of instruments provided for herein
and supersedes all prior conflicting or inconsistent agreements, consents, and understandings
relating to such subject matter.

     18. SEVERABILITY. EACH PROVISION OF THIS AMENDMENT SHALL BE CONSIDERED SEVERABLE AND
IF FOR ANY REASON ANY PROVISION OR PROVISIONS HEREIN ARE DETERMINED TO BE INVALID, UNENFORCEABLE OR
ILLEGAL UNDER ANY EXISTING OR FUTURE LAW, SUCH INVALIDITY, UNENFORCEABILITY OR ILLEGALITY SHALL NOT
IMPAIR THE OPERATION OF OR AFFECT THOSE PORTIONS OF THIS AMENDMENT THAT ARE VALID, ENFORCEABLE AND
LEGAL.

     19. All the terms and provisions of the Partnership Agreement, as amended hereby, are hereby
ratified, confirmed, and adopted.

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