Entities has taken any action, directly or indirectly, that would result in a
violation of the Foreign Corrupt Practices Act of 1977, as amended, and the
rules and regulations thereunder (the “FCPA”), including, without limitation,
making use of the mails or any means or instrumentality of interstate commerce
corruptly in furtherance of an offer, payment, promise to pay or authorization
of the payment of any money, or other property, gift, promise to give, or
authorization of the giving of anything of value to any “foreign official” (as
such term is defined in the FCPA) or any foreign political party or official
thereof or any candidate for foreign political office, in contravention of the
FCPA, or of the Bribery Act 2010 of the United Kingdom, and the Partnership
Entities and, to the knowledge of the Partnership, their Affiliates have
conducted their businesses in compliance with the FCPA and have instituted and
maintain policies and procedures designed to ensure, and which are reasonably
expected to continue to ensure, continued compliance therewith.
(b)    The operations of the Partnership Entities are and have been conducted at
all times in compliance in all material respects with applicable financial
recordkeeping and reporting requirements of the Currency and Foreign
Transactions Reporting Act of 1970, as amended, the money laundering statutes of
all applicable jurisdictions, the rules and regulations thereunder and any
related or similar rules, regulations or guidelines issued, administered or
enforced by any court, arbitrator, regulatory body, administrative agency,
governmental body or other authority or agency that, in each case, are
applicable to the business and operations of the Partnership and the
Subsidiaries (collectively, the “Money Laundering Laws”). No action, suit or
proceeding by or before any court, arbitrator, regulatory body, administrative
agency, governmental body or other authority or agency involving the Partnership
Entities with respect to the Money Laundering Laws is pending or, to the
Partnership’s knowledge, threatened.
Section 3.30    OFAC. None of the Partnership Entities nor, to the Partnership’s
knowledge, any director, officer, agent, employee or affiliate of any of the
Partnership Entities is currently subject to any U.S. sanctions administered by
the Office of Foreign Assets Control of the U.S. Treasury Department (“OFAC”).
The Partnership will not directly or indirectly use the proceeds from the sale
of the Purchased Units, or lend, contribute or otherwise make available such
proceeds, to any subsidiary, joint venture partner or other person or entity in
any manner that, to the Partnership’s knowledge, would result in a violation of
any economic sanctions imposed by the United States (including any administered
or enforced by OFAC, the U.S. Department of State, or the Bureau of Industry and
Security of the U.S. Department of Commerce), the United Nations Security
Council, the European Union, or the United Kingdom (including sanctions
administered or controlled by Her Majesty’s Treasury) (collectively, “Sanctions”
and such persons, “Sanctioned Persons”).
Section 3.31    Sanctions. None of the Partnership Entities nor, to the
knowledge of the Partnership, any director, officer, agent, employee or
affiliate of any of the Partnership Entities, is a person that is, or is 50% or
more owned or otherwise controlled by a person that is: (a) the subject of any
Sanctions; or (b) located, organized or resident in Burma (Myanmar), Cuba, Iran,
North Korea, Sudan, and Syria (collectively, “Sanctioned Countries” and each, a
“Sanctioned Country”). Except as has been disclosed to the Purchasers or is not
material to the analysis under any Sanctions, none of the Partnership Entities
has engaged in any dealings or transactions with or for the benefit of a

16

--------------------------------------------------------------------------------

Sanctioned Person, or with or in a Sanctioned Country, in the preceding 3 years,
nor does any Partnership Entity have any plans to initiate any dealings or
transactions with Sanctioned Persons, or with or in Sanctioned Countries.
Section 3.32    Certain Fees. Other than as described in the Placement Agent
Engagement Letter, none of the Partnership Entities is a party to any contract,
agreement or understanding with any Person (other than this Agreement) that
would give rise to a valid claim against any of them or the Purchasers for a
brokerage commission, finders’ fee or like payment in connection with the
offering and sale of the Purchased Units. The Partnership agrees that it will
indemnify and hold harmless each Purchaser from and against any and all claims,
demands or liabilities for broker’s, finder’s, placement or other similar fees
or commissions incurred by the Partnership in connection with the purchase of
the Purchased Units or the consummation of the transactions contemplated by this
Agreement.
Section 3.33    No Side Agreements. There are no agreements by, among or between
the Partnership or any of its Affiliates, on the one hand, and any Purchaser or
any of their Affiliates, on the other hand, with respect to the transactions
contemplated hereby other than the Operative Documents nor promises or
inducements for future transactions between or among any of such parties.
Section 3.34    No Registration. Assuming the accuracy of the representations
and warranties of the Purchaser contained in Section 4.6 and Section 4.7, the
issuance and sale of the Purchased Units pursuant to this Agreement is exempt
from registration requirements of the Securities Act, and neither the
Partnership nor, to the knowledge of the Partnership, any authorized
Representative acting on its behalf has taken or will take any action hereafter
that would cause the loss of such exemption.
Section 3.35    No Integration. The Partnership has not, directly or through any
agent, issued, sold, offered for sale, solicited offers to buy or otherwise
negotiated in respect of, any security (as defined in the Securities Act), that
is or will be integrated with the issuance and sale of the Purchased Units
contemplated by this Agreement pursuant to the Securities Act, the rules and
regulations thereunder or the interpretations thereof by the Commission.
Section 3.36    MLP Status. The Partnership is properly treated as a partnership
for United States federal income tax purposes, and more than 90% of the
Partnership’s gross income for the current period is, and for each of the
Partnership’s taxable years ending after September 20, 2016 has been,
“qualifying income” under Section 7704(d) of the Code.
Section 3.37    Qualifying Income of Contributed Interests. The Partnership
expects that more than 90% of the gross income of the Partnership in 2017 after
the closing date of the transactions contemplated by the Contribution Agreement
will be “qualifying income” under Section 7704(d) of the Code.
Section 3.38    Investment Company. None of the Partnership Entities is and, as
of the Closing Date after giving effect to the offer and sale of the Purchased
Units and the application of the proceeds therefrom, none of them will be, (a)
an “investment company” or a company “controlled” by an “investment company”
within the meaning of the Investment Company Act of 1940, as amended, and the
rules and regulations of the Commission thereunder (collectively, the
“Investment Company Act”) or (b) a “business development company” (as defined in
Section 2(a)(48) of the Investment Company Act).
Section 3.39    Disclosure Controls and Procedures. To the extent required by
Rule 13a-15 under the Exchange Act, the Partnership has established and
maintains an effective system of “disclosure controls and procedures” (as
defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) that complies
with the requirements of the Exchange Act; the Partnership’s “disclosure
controls and procedures” are reasonably designed to ensure that all information
(both financial and non-financial) required to be disclosed by the Partnership
in the reports to be filed or submitted under the Exchange Act is recorded,
processed, summarized and reported within the time periods specified in the
Exchange Act, and that all such information is accumulated and communicated to
the Partnership’s management as appropriate to allow timely decisions regarding
required disclosure and to make the certifications of the Chief Executive
Officer and Chief Financial Officer of the General Partner required under the
Exchange Act with respect to such reports.

17

--------------------------------------------------------------------------------

Section 3.40    Internal Controls. The Partnership Entities maintain systems of
“internal control over financial reporting” (as defined in Rule 13a-15(f) of the
Exchange Act) that comply with the requirements of the Exchange Act and have
been designed by, or under the supervision of, their respective principal
executive and principal financial officers, or persons performing similar
functions, to provide reasonable assurance regarding the reliability of
financial reporting and the preparation of financial statements for external
purposes in accordance with GAAP, including, but not limited to, internal
accounting controls sufficient to provide reasonable assurance that
(a) transactions are executed in accordance with management’s general or
specific authorizations; (b) transactions are recorded as necessary to permit
preparation of financial statements in conformity with GAAP and to maintain
asset accountability; (c) access to assets is permitted only in accordance with
management’s general or specific authorization; and (d) the recorded
accountability for assets is compared with the existing assets at reasonable
intervals and appropriate action is taken with respect to any differences. As of
the date of the most recent balance sheet of the Partnership and its
consolidated subsidiaries reviewed or audited by KPMG LLP, there were no
material weaknesses or significant deficiencies in the Partnership’s internal
controls. Except as disclosed in the SEC Reports, the Partnership is not aware
of (i) any material weakness in its internal control over financial reporting or
(ii) any change in internal control over financial reporting that has materially
affected, or is reasonably likely to materially affect, the Partnership’s
internal control over financial reporting.
Section 3.41    Placement Agent Reliance. The Partnership acknowledges that the
Placement Agents may rely upon the representations and warranties made by the
Partnership to each Purchaser in this Agreement.
Section 3.42    Legal Sufficiency of the Contribution Agreement. The
Contribution Agreement is legally sufficient to transfer or convey to the
Partnership (a) all of the transferor’s right, title and interest in and to the
Contributed Interests and (b) all of the ownership interests, assets and rights
in and to the Contributed Interests purported to be transferred thereby, subject
to the conditions, reservations, encumbrances and limitations contained in the
Contribution Agreement. The Partnership, upon consummation of the transactions
contemplated by the Contribution Agreement, will directly or indirectly succeed
in all material respects to the Contributed Interests.
Section 3.43    Absence of Price Manipulation. Neither the Partnership nor, to
the knowledge of the Partnership, any of its Affiliates or its or their
respective directors or officers, has taken, or will take, directly or
indirectly, any action designed to, or that might reasonably be expected to,
cause or result in stabilization or manipulation of the price of the Common
Units to facilitate the sale or resale of the Purchased Units in violation of
Regulation M under the Exchange Act.
ARTICLE IV
REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS
Each Purchaser, severally and not jointly, hereby represents and warrants to the
Partnership that:
Section 4.1    Existence. Such Purchaser is duly organized and validly existing
and in good standing under the Laws of its jurisdiction of organization, with
all requisite power and authority to own, lease, use and operate its properties
and to conduct its business as currently conducted, except where the failure to
have such power or authority would not prevent the consummation of the
transactions contemplated by this Agreement and the Registration Rights
Agreement.
Section 4.2    Authorization, Enforceability. Such Purchaser has all necessary
corporate, limited liability company or partnership power and authority to
execute, deliver and perform its obligations under this Agreement and the
Registration Rights Agreement and to consummate the transactions contemplated
hereby and thereby, and the execution, delivery and performance by such
Purchaser of this Agreement and the Registration Rights Agreement has been duly
authorized by all necessary action on the part of such Purchaser; and this
Agreement and the Registration Rights Agreement constitute the legal, valid and
binding obligations of such Purchaser, enforceable in accordance with their
terms, subject to the Enforceability Exceptions.
Section 4.3    No Breach. The execution, delivery and performance of this
Agreement and the Registration Rights Agreement by such Purchaser and the
consummation by such Purchaser of the transactions contemplated hereby

18

--------------------------------------------------------------------------------

and thereby will not (a) conflict with or result in a breach or violation of any
of the terms or provisions of, or constitute a default under, any material
agreement to which such Purchaser is a party or by which such Purchaser is bound
or to which any of the property or assets of such Purchaser is subject, (b)
conflict with or result in any violation of the provisions of any certificate of
limited partnership, formation or incorporation, agreement of limited
partnership, limited liability company agreement, bylaws or any other
organizational documents of such Purchaser, or (c) violate any statute, order,
rule or regulation of any court or governmental agency or body having
jurisdiction over such Purchaser or the property or assets of such Purchaser,
except in the cases of clauses (a) and (c), for such conflicts, breaches,
violations or defaults as would not prevent the consummation of the transactions
contemplated by this Agreement and the Registration Rights Agreement.
Section 4.4    Certain Fees. No fees or commissions are or will be payable by
such Purchaser to brokers, finders, or investment bankers with respect to the
purchase of any of the Purchased Units or the consummation of the transaction
contemplated by this Agreement.
Section 4.5    No Side Agreements. There are no other agreements by, among or
between such Purchaser and any of its Affiliates, on the one hand, and the
Partnership or any of its Affiliates, on the other hand, with respect to the
transactions contemplated hereby, other than the Operative Documents, nor
promises or inducements for future transactions between or among any of such
parties.
Section 4.6    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 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 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 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). If such Purchaser
should in the future decide to dispose of any of the Purchased Units, the
Purchaser understands and agrees (a) that it may do so only in compliance with
the Securities Act and applicable state securities law, as then in effect,
including a sale contemplated by any registration statement pursuant to which
such securities are being offered, or pursuant to an exemption from the
Securities Act, and (b) that stop-transfer instructions to that effect will be
in effect with respect to such securities.
Section 4.7    Nature of Purchaser. Such Purchaser represents and warrants to,
and covenants and agrees with, the Partnership 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, (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 and (c) 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 4.8    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 the Partnership in a
transaction not involving a public offering and that under such Laws and
applicable regulations such securities may not be resold absent registration
under the Securities Act or an exemption therefrom. In this connection, such
Purchaser represents that it is knowledgeable with respect to Rule 144 of the
Commission promulgated under the Securities Act.
Section 4.9    Legend. Such Purchaser understands that the book entry evidencing
the Purchased Units will bear the legend required by the Partnership Agreement
as well as a legend substantively consistent with the following legend: “These
securities have not been registered under the Securities Act of 1933, as amended
(the “Securities Act”). 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

19

--------------------------------------------------------------------------------

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 4.10    Partnership Information. Such Purchaser acknowledges and agrees
that the Partnership has provided or made available to such Purchaser (through
EDGAR, the Partnership’s website or otherwise) all SEC Reports, as well as all
press releases or investor presentations issued by the Partnership through the
date of this Agreement that are included in a filing by the Partnership on Form
8-K or clearly posted on the Partnership’s website.
Section 4.11    Placement Agent Reliance. Such Purchaser agrees that the
Placement Agent may rely upon the representations and warranties made by such
Purchaser to the Partnership in Sections 4.6, 4.7 and 4.8 of this Agreement.
Section 4.12    Short Selling. Such Purchaser represents that it has not entered
into any Short Sales of the Common Units owned by it since the time it first
began discussions with the Partnership or the Placement Agents about the
transactions contemplated by this Agreement; provided, however, subject to such
Purchaser’s compliance with its obligations under the U.S. federal securities
laws and its internal policies, the above shall not apply, in the case of a
Purchaser that is a large multi-unit investment or commercial banking
organization, to activities in the normal course of trading units of such
Purchaser; provided, further, that subject to such Purchaser’s compliance with
its obligations under the U.S. federal securities laws and its internal
policies: (a) such 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 such
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 such Purchaser that was effected by a Walled Off Person in
the ordinary course of trading without the advice or participation of such
Purchaser or receipt of confidential or other information regarding this
transaction provided by such Purchaser to such entity.
ARTICLE V
COVENANTS
Section 5.1    Taking of Necessary Action. Each of the parties hereto shall use
its 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,
the Partnership 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
Operative Documents; provided, however, and notwithstanding anything to the
contrary, that no Purchaser is under any obligation by reason of this Section
5.1 to make, seek or receive any filings, notifications, consents,
determinations, authorizations, permits, approvals, licenses or the like with or
provide any documentation or information to any regulatory or self-regulatory
body having jurisdiction over the Partnership or Purchaser other than
information that is already included in this Agreement or is otherwise in the
public domain other than as may be requested by the Commission or pursuant to
any applicable securities or “Blue Sky” laws of the United States. The
Partnership shall promptly and accurately respond, and shall use its
commercially reasonable efforts to cause its transfer agent to respond, to
reasonable requests for information (which is otherwise not publicly available)
made by a Purchaser or its auditors relating to the actual holdings of such
Purchaser or its accounts; provided, that the Partnership shall not be obligated
to provide any such information that could reasonably result in a violation of
applicable Law or conflict with the Partnership’s insider trading policy or a
confidentiality obligation of the Partnership. The Partnership shall use its
commercially reasonable efforts to cause its transfer agent to reasonably
cooperate with each Purchaser to ensure that the Purchased Units are validly and
effectively issued to such Purchaser and that such Purchaser’s ownership of the
Purchased Units following the Closing is accurately reflected on the appropriate
books and records of the Partnership’s transfer agent.
Section 5.2    Other Actions. The Partnership shall file prior to the Closing a
supplemental listing application with the NYSE to list the Purchased Units.

20

--------------------------------------------------------------------------------

Section 5.3    Contribution Transaction. The Partnership will distribute to NBL
Midstream an amount equal to the net proceeds of this offering as cash
consideration. If the transactions contemplated by the Contribution Agreement
are not closed on the same Business Day as the Closing, the Partnership shall
return to each Purchaser its Purchase Price within two Business Days of receipt
thereof and each Purchaser shall promptly return its Purchased Units to the
Partnership.
Section 5.4    Expenses. The Partnership shall pay up to $75,000 of legal fees
of Gibson, Dunn & Crutcher LLP, counsel to the Purchasers, incurred in
connection with the negotiation, execution, delivery and performance of this
Agreement and the Registration Rights Agreement and the transactions
contemplated hereby and thereby, provided that any request for such payment is
accompanied by a satisfactory written invoice for such expenses. If any action
at law or equity is necessary to enforce or interpret the terms of any Operative
Document, the prevailing party shall be entitled to reasonable attorney’s fees,
costs and necessary disbursements in addition to any other relief to which such
party may be entitled. Any legal fees of Gibson, Dunn & Crutcher LLP in excess
of $75,000 shall be paid pro rata by all the Purchasers in proportion to the
number of Purchased Units purchased by each.
Section 5.5    Non-Public Information. On or before 9:00 a.m., New York local
time, on the Business Day immediately following the date hereof, the Partnership
shall issue a press release (the “Press Release”) announcing the entry into this
Agreement and describing the terms of the transactions contemplated by this
Agreement and any other material, nonpublic information that the Partnership may
have provided any Purchaser at any time prior to the issuance of the Press
Release. On or before the fourth Business Day following the date hereof, the
Partnership shall file a Current Report on Form 8-K with the Commission
describing the terms of the transactions contemplated by the Operative
Documents, and including as an exhibit to such Current Report on Form 8-K the
Operative Documents, in the form required by the Exchange Act.
ARTICLE VI
INDEMNIFICATION
Section 6.1    Indemnification by the Partnership. The Partnership agrees to
indemnify each Purchaser and its 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 reimburse each of them for all 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
the Partnership contained herein, provided that such claim for indemnification
relating to a breach of the representations or warranties is made prior to the
expiration of the survival period for such representations or warranties; and
provided further, that no Purchaser Related Party shall be entitled to recover
special, consequential (including lost profits) or punitive damages.
Notwithstanding anything to the contrary, consequential damages shall not be
deemed to include diminution in value of the Purchased Units, which is
specifically included in damages covered by Purchaser Related Parties’
indemnification above.
Section 6.2    Indemnification Procedure. Promptly after receipt by an
indemnified party under this Article VI of notice of any claim or the
commencement of any action, the indemnified party shall, if a claim in respect
thereof is to be made against the indemnifying party under this Article VI,
notify the indemnifying party in writing of the claim or the commencement of
that action; provided, however, that the failure to notify the indemnifying
party shall not relieve it from any liability which it may have under Section
6.1 of this Article VI except to the extent it has been materially prejudiced
(through the forfeiture of substantive rights and defenses) by such failure and,
provided, further, that the failure to notify the indemnifying party shall not
relieve it from any liability which it may have to an indemnified party
otherwise than under this Article VI. If any such claim or action shall be
brought against an indemnified party, and it shall notify the indemnifying party
thereof, the indemnifying party shall be entitled to participate therein and, to
the extent that it wishes, jointly with any other similarly notified
indemnifying party, to assume the defense thereof with counsel reasonably
satisfactory to the indemnified party. After notice from the indemnifying party
to the indemnified party of its election to assume the defense of such claim or
action, the indemnifying party shall not be

21

--------------------------------------------------------------------------------

liable to the indemnified party under this Article VI for any legal or other
expenses subsequently incurred by the indemnified party in connection with the
defense thereof other than reasonable costs of investigation; provided, however,
that the indemnified party shall have the right to employ counsel to represent
jointly the indemnified party and those other indemnified parties and their
respective directors, officers, employees and controlling persons who may be
subject to liability arising out of any claim in respect of which indemnity may
be sought under this Article VI if (a) the indemnified party and the
indemnifying party shall have so mutually agreed; (b) the indemnifying party has
failed within a reasonable time to retain counsel reasonably satisfactory to the
indemnified party; (c) the indemnified party and its directors, officers,
employees and controlling persons shall have reasonably concluded that there may
be legal defenses available to them that are different from or in addition to
those available to the indemnifying party; or (d) the named parties in any such
proceeding (including any impleaded parties) include both the indemnified
parties or their respective directors, officers, employees or controlling
persons, on the one hand, and the indemnifying party, on the other hand, and
representation of both sets of parties by the same counsel would be
inappropriate due to actual or potential differing interests between them, and
in any such event the fees and expenses of such separate counsel shall be paid
by the indemnifying party. No indemnifying party shall (i) without the prior
written consent of the indemnified parties (which consent shall not be
unreasonably withheld), settle or compromise or consent to the entry of any
judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability
arising out of such claim, action, suit or proceeding and does not include a
statement as to, or an admission of fault, culpability or a failure to act by or
on behalf of any indemnified party, or (ii) be liable for any settlement of any
such action effected without its written consent (which consent shall not be
unreasonably withheld), but if settled with the consent of the indemnifying
party or if there be a final judgment for the plaintiff in any such action, the
indemnifying party agrees to indemnify and hold harmless any indemnified party
from and against any loss or liability by reason of such settlement or judgment.
Notwithstanding the foregoing sentence, if at any time an indemnified party
shall have requested an indemnifying party to reimburse the indemnified party
for fees and expenses of counsel to the extent required by Section 6.1 hereof,
the indemnifying party agrees that it shall be liable for any settlement of any
proceeding effected without its written consent if (x) such settlement is
entered into more than 30 days after receipt by such indemnifying party of the
aforesaid request and (y) such indemnifying party shall not have reimbursed the
indemnified party in accordance with such request or disputed in good faith the
indemnified party’s entitlement to such reimbursement prior to the date of such
settlement.

this Agreement and the provisions of Article VI shall remain operative and in
full force and effect unless such obligations are expressly terminated in a
writing by the parties, regardless of any purported general termination of this
Agreement.
Section 7.3    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

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 by the Partnership 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

or to such other address as the Partnership or such Purchaser may designate in
writing. All notices and communications shall be deemed to have been duly given:
at the time delivered by hand, if personally delivered; at the time of
transmittal, if sent via electronic mail; upon actual receipt if sent by
certified mail, return receipt requested, or regular mail, if mailed; when
receipt acknowledged, if sent via facsimile; and upon actual receipt when
delivered to an air courier guaranteeing overnight delivery.
Section 7.7    Removal of Legend. The Partnership, at its sole cost, shall
remove the legend described in Section 4.9 (or instruct its transfer agent to so
remove such legend) from the certificates evidencing Purchased Units issued and
sold to each Purchaser pursuant to this Agreement if (a) such Purchased Units
are sold pursuant to an effective registration statement under the Securities
Act, (b) such Purchased Units are sold or transferred pursuant to Rule 144 (if
the transferor is not an Affiliate of the Partnership), or (c) such Purchased
Units are eligible for sale under Rule 144, without the requirement for the
Partnership to be in compliance with the current public information required
under Rule 144(c)(1) (or Rule 144(i)(2), if applicable) as to such securities
and without volume or manner of sale restrictions. In connection with a sale of
the Purchased Units by a Purchaser in reliance on Rule 144, the applicable
Purchaser shall deliver to the transfer agent and the Partnership a customary
representation letter providing to the transfer agent and the Partnership any
information the Partnership deems reasonably 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 the Purchaser is not an Affiliate of
the Partnership and regarding the length of time the Purchased Units have been
held. Upon receipt of such representation letter, the Partnership shall promptly
direct its transfer agent to remove the legend referred to in Section 4.9 from
the appropriate book-entry accounts maintained by the transfer agent, and the
Partnership shall bear all costs associated therewith. After any Purchaser or
its permitted assigns have held the Purchased Units for such time as
non-Affiliates are permitted to sell without volume limitations under Rule 144,
if the certificate for such Purchased Units still bears the restrictive legend
referred to in Section 4.9, the Partnership agrees, upon request of the
Purchaser or permitted assignee, to take all steps necessary to promptly effect
the removal of the legend described in Section 4.9 from the Purchased Units, and
the Partnership shall bear all costs associated therewith, 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 the Partnership any information
the Partnership deems reasonably 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 the Partnership (and a
covenant to inform the Partnership if it should thereafter become an Affiliate
and to consent to exchange its certificates for certificates bearing an
appropriate restrictive legend) and regarding the length of time the Purchased
Units have been held.
Section 7.8    Entire Agreement. This Agreement, the other Operative 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 and therein. There are no
restrictions, promises, representations, warranties or undertakings, other than
those set forth or referred to herein or the other Operative Documents with
respect to the rights granted by the Partnership or any of its Affiliates or any
Purchaser or any of its Affiliates set forth herein or therein. This Agreement,
the other Operative Documents and the other agreements and documents referred to
herein or therein supersede all prior agreements and understandings between the
parties with respect to such subject matter.

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. In the event that any signature is delivered by
facsimile transmission or by e-mail delivery of a “.pdf” format data file, such
signature shall create a valid and binding obligation of the party executing (or
on whose behalf such signature is executed) with the same force and effect as if
such facsimile or “.pdf” signature page were an original thereof.
Section 7.11    Termination.
(a)    Notwithstanding anything herein to the contrary, this Agreement may be
terminated at any time at or prior to the Closing by any Purchaser (with respect
to such Purchaser only), upon a breach in any material respect by the
Partnership of any covenant or agreement set forth in this Agreement.
(b)    Notwithstanding anything herein to the contrary, this Agreement shall
automatically terminate at any time at or prior to the Closing:
(i)    if a statute, rule, order, decree or regulation 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 makes the
transactions contemplated by this Agreement illegal; or
(ii)    if the Closing shall not have occurred by June 30, 2017.
(c)    In the event of the termination of this Agreement as provided in this
Section 7.11, this Agreement shall forthwith become null and void. In the event
of such termination, there shall be no liability on the part of any party
hereto, except as set forth in Section 5.3 and Article VI of this Agreement.
Section 7.12    Recapitalization, Exchanges, Etc. Affecting the Common Units.
The provisions of this Agreement shall apply to the full extent set forth herein
with respect to any and all equity interests of the Partnership or any successor
or assign of the Partnership (whether by merger, consolidation, sale of assets
or otherwise) which may be issued in respect of, in exchange for or in
substitution of, the Common Units, and shall be appropriately adjusted for
combinations, unit splits, recapitalizations and the like occurring after the
