 ARTICLE II 

REGISTRATION RIGHTS 

Section 2.01. Demand Registration. Upon the written request (a “Notice”) by Holders collectively owning at least
5% of the then-outstanding Registrable Securities, the Partnership shall file with the Commission, as soon as reasonably practicable, but in no event more than 90 days following the receipt of the Notice, a registration statement (each a
“Registration Statement”) under the Securities Act providing for the resale of such Registrable Securities (which may, at the option of the Holders giving such Notice, be a registration statement under the Securities Act that
provides for the resale of such Registrable Securities pursuant to Rule 415 from time to time by the Holders). There shall be no limit on the number of Registration Statements that may be required by the Holders pursuant to this
Section 2.01. The Partnership shall use its commercially reasonable efforts to cause each Registration Statement to be declared effective by the Commission as soon as reasonably practicable after the initial filing of the

 
Registration Statement. Any Registration Statement shall provide for the resale pursuant to any method or combination of methods legally available to, and requested by, the Holders of any and all
such Registrable Securities covered by such Registration Statement. The Partnership shall use its commercially reasonable efforts to cause each Registration Statement filed pursuant to this Section 2.01 to be continuously effective,
supplemented and amended to the extent necessary to ensure that it is available for the resale of all such Registrable Securities by the Holders until all such Registrable Securities covered by such Registration Statement have ceased to be
Registrable Securities (the “Effectiveness Period”). Each Registration Statement when effective (and the documents incorporated therein by reference) shall comply as to form in all material respects with all applicable requirements
of the Securities Act and the Exchange Act and shall 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 (in the case of any
prospectus contained in such Registration Statement, in light of the circumstances under which a statement is made). 
 Section 2.02.
Underwritten Offerings. 
 (a) Request for Underwritten Offering. In the event that Holders collectively holding at least 5% of
the then-outstanding Registrable Securities elect to dispose of Registrable Securities under a Registration Statement pursuant to an Underwritten Offering, and such Holders reasonably anticipate gross proceeds of at least $50 million pursuant to
such Underwritten Offering, the Partnership shall, upon request by such Holders, retain underwriters in order to permit such Holders to effect such sale through an Underwritten Offering and take all commercially reasonable actions as are requested
by the Managing Underwriter to expedite or facilitate the disposition of such Registrable Securities. The Partnership shall, upon request of the Holders, cause its management to participate in a roadshow or similar marketing effort in connection
with any such Underwritten Offering. 
 (b) Limitation on Underwritten Offerings. In no event shall the Partnership be required
hereunder to participate in more than three Underwritten Offerings in any 12-month period. 
 (c) General Procedures. In connection
with any Underwritten Offering pursuant to this Section 2.02, the Holders of a majority of the Registrable Securities being sold in such Underwritten Offering shall be entitled, subject to the Partnership’s consent (which is not to
be unreasonably withheld), to select the Managing Underwriter. In connection with any Underwritten Offering under this Agreement, each Selling Holder and the Partnership shall be obligated to enter into an underwriting agreement that contains such
representations and warranties, covenants, indemnities and other rights and obligations as are customary in underwriting agreements for firm commitment offerings of securities. No Selling Holder may participate in such 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 and furnish to the Partnership such information as the Partnership may reasonably request for inclusion in a Registration Statement or prospectus or any amendment or supplements thereto, as the case may be. 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 such Selling Holder’s obligations. If any Selling Holder disapproves of the terms of an Underwritten Offering contemplated by
this Section 2.02, such Selling Holder may elect to withdraw from the Underwritten Offering by notice to the Partnership and the Managing Underwriter; provided, however, that such withdrawal must be made at a time prior to the
time of pricing of such Underwritten Offering. No such withdrawal shall affect the Partnership’s obligation to pay Registration Expenses. 

Section 2.03. Delay Rights. Notwithstanding anything to the contrary contained herein, if the Partnership determines that its
compliance with its obligations under this Article II would be materially detrimental to the Partnership because such compliance would (a) materially interfere with a significant acquisition, reorganization, financing or other similar
transaction involving the Partnership, (b) require premature disclosure of material information that the Partnership has a bona fide business purpose for preserving as confidential or (c) render the Partnership unable to comply with
applicable securities laws, then the Partnership shall have the right to postpone compliance with its obligations under this Article II for a period of not more than three months, provided, that such right pursuant to this
Section 2.03 may not be utilized more than twice in any 12-month period. 
 Section 2.04. Sale Procedures. In
connection with its obligations under this Article II, the Partnership will, as promptly as reasonably practicable: 
 (a) prepare
and file with the Commission such amendments and supplements to each Registration Statement and the prospectus used in connection therewith as may be necessary to keep each 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 such Registration Statement; 

(b) if a prospectus supplement will be used in connection with the marketing of an Underwritten Offering and the Managing Underwriter notifies
the Partnership in writing that, in the sole judgment of such Managing Underwriter, inclusion of detailed information in such prospectus supplement is of material importance to the success of the Underwritten Offering of such Registrable Securities,
use commercially reasonable efforts to include such information in such prospectus supplement; 
 (c) furnish to each Selling Holder
(i) as far in advance as reasonably practicable before filing a 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 a Registration Statement or supplement or amendment thereto, and (ii) such
number of copies of such Registration Statement and the prospectus included therein and any supplements and amendments thereto as such Persons may reasonably request in order to facilitate the public sale or other disposition of the Registrable
Securities covered by such Registration Statement; 

 (d) if applicable, use its commercially reasonable efforts to register or qualify the
Registrable Securities covered by a Registration Statement under the securities or blue sky laws of such jurisdictions as the Selling Holders or, in the case of an Underwritten Offering, the Managing Underwriter, 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 that would subject it to general service of process
in any jurisdiction where it is not then so subject; 
 (e) promptly notify each Selling Holder and each underwriter, at any time
when a prospectus is required to be delivered under the Securities Act, of (i) the filing of a 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 Registration Statement or any post-effective amendment thereto, when the same has become effective; and (ii) 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 a Registration Statement or any prospectus or prospectus supplement thereto; 

(f) immediately notify each Selling Holder and each underwriter, at any time when a prospectus 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 a 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 in order to make the statements therein not misleading (in the case of the prospectus contained therein, in the light of the circumstances under which a statement is made); (ii) the
issuance or threat of issuance by the Commission of any stop order suspending the effectiveness of a 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 in order to make the statements therein not misleading in the light of the circumstances then existing and to take such other commercially reasonable action as is necessary to remove a stop order,
suspension, threat thereof or proceedings related thereto; 
 (g) 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 any offering of Registrable Securities; 
 (h) in the case of an Underwritten Offering, furnish upon
request, (i) an opinion of counsel for the Partnership dated the date of the closing under the underwriting agreement and 

 
(ii) a “cold comfort” letter, dated the pricing date of such Underwritten Offering (to the extent available) and a letter of like kind dated the date of the closing under the
underwriting agreement, in each case, signed by the independent public accountants who have certified the Partnership’s financial statements included or incorporated by reference into the applicable registration statement, and each of the
opinion and the “cold comfort” letter shall be in customary form and covering substantially the same matters with respect to such registration statement (and the prospectus and any prospectus supplement included therein) as have been
customarily covered in opinions of issuer’s counsel and in accountants’ letters delivered to the underwriters in Underwritten Offerings of securities by the Partnership and such other matters as such underwriters and Selling Holders may
reasonably request; 
 (i) 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;

 (j) make available to the appropriate representatives of the Managing Underwriter and Selling Holders access to such information and
Partnership personnel as is reasonable and customary to enable such parties to establish a due diligence defense under the Securities Act; 

(k) cause all 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; 
 (l) 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 the Registrable Securities; 
 (m) provide a transfer agent and registrar for all Registrable Securities covered by a
Registration Statement not later than the effective date of such registration statement; and 
 (n) enter into customary agreements and take
such other actions as are reasonably requested by the Selling Holders or the underwriters, if any, in order to expedite or facilitate the disposition of the Registrable Securities. 

Each Selling Holder, upon receipt of notice from the Partnership of the happening of any event of the kind described in subsection (f) of
this Section 2.04, shall forthwith discontinue disposition of the Registrable Securities by means of a prospectus or prospectus supplement until such Selling Holder’s receipt of the copies of the supplemented or amended prospectus
contemplated by subsection (f) of this Section 2.04 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, if any, to deliver to the Partnership all copies in their possession or control of the prospectus and any
prospectus supplement covering such Registrable Securities current at the time of receipt of such notice. 

 Section 2.05. Cooperation by Holders. The Partnership shall have no obligation to
include in a Registration Statement, or in an Underwritten Offering pursuant to Section 2.02(a), Registrable Securities of a Selling Holder 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 or prospectus supplement, as applicable, to comply with the Securities Act. 

Section 2.06. Expenses. The Partnership will pay all reasonable Registration Expenses, including in the case of an Underwritten
Offering, regardless of whether any sale is made in such Underwritten Offering. Each Selling Holder shall pay all Selling Expenses in connection with any sale of its Registrable Securities hereunder. In addition, except as otherwise provided in
Section 2.07, the Partnership shall not be responsible for legal fees incurred by Holders in connection with the exercise of such Holders’ rights hereunder. 

Section 2.07. 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 participating therein, its directors, officers, employees and agents, and each Person, if any, who controls such Selling Holder within the meaning of the Securities Act
and the Exchange Act, and its directors, officers, employees or agents, against any losses, claims, damages, expenses or liabilities (including reasonable attorneys’ fees and expenses) (collectively, “Losses”), joint or
several, to which such Selling Holder, director, officer, employee, agent or controlling 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 or any Written Testing-the-Waters Communication, in the light of the circumstances
under which such statement is made) contained in any Written Testing-the-Waters Communication, a Registration Statement, any preliminary prospectus or prospectus supplement, free writing prospectus or final prospectus or prospectus supplement
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 or any Written Testing-the-Waters Communication, in the light of the circumstances under which they were made) not misleading, and will reimburse each such Selling Holder, its directors, officers, employee and agents, and each such
controlling Person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Loss or actions or proceedings as such expenses are incurred; 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, its directors, officers, employees and agents or such controlling Person in writing specifically for use in any Written Testing-the-Waters Communication, a Registration Statement, or prospectus or any amendment or supplement thereto, as
applicable. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Selling Holder or any such directors, officers, employees agents or controlling 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, its 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 any Written Testing-the-Waters Communication, a Registration Statement, any preliminary prospectus or prospectus supplement, free writing prospectus or final prospectus or prospectus supplement 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 that it may have to any indemnified party other than under this Section 2.07. 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 2.07 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 as incurred. Notwithstanding any other provision of this Agreement, no indemnified party shall settle any action brought
against it with respect to which it is entitled to indemnification hereunder without the consent of the indemnifying party, unless the settlement thereof imposes no liability or obligation on, and includes a complete and unconditional release from
all liability of, the indemnifying party. 
 (d) Contribution. If the indemnification provided for in this Section 2.08
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 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 that resulted in such Losses, as well as any other relevant equitable considerations; provided, however, that in no event shall the
Selling Holder be required to contribute an aggregate amount in excess of the 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 that 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 that 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 fraudulent misrepresentation. 
 (e) Other Indemnification. The provisions of this
Section 2.07 shall be in addition to any other rights to indemnification or contribution that an indemnified party may have pursuant to law, equity, contract or otherwise. 

Section 2.08. 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 under 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 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 via EDGAR, 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 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. 

Section 2.09. Transfer or Assignment of Registration Rights. The rights to cause the Partnership to register Registrable
Securities granted to a Holder by the Partnership under this Article II may be transferred or assigned by such Holder to one or more transferee(s) or assignee(s) of such Registrable 

 
Securities; provided, however, that (a) unless such transferee or assignee is an Affiliate of the Sponsor, each such transferee or assignee holds Registrable Securities representing at least
5% of the then outstanding Registrable Securities, (b) the Partnership is given written notice prior to any said transfer or assignment, stating the name and address of each such transferee or assignee and identifying the Registrable Securities
with respect to which such registration rights are being transferred or assigned and (c) each such transferor or assignor agrees to be bound by this Agreement. 

Section 2.10. Restrictions on Public Sale by Holders of Registrable Securities. Each Holder agrees to enter into a customary
letter agreement with underwriters providing such Holder will not affect any public sale or distribution of the Registrable Securities during the 90 calendar day period beginning on the date of a prospectus or prospectus supplement filed with the
Commission with respect to the pricing of an Underwritten Offering, provided that (i) the duration of the foregoing restrictions shall be no longer than the duration of the shortest restriction generally imposed by the underwriters on the
Partnership or the officers, directors or any other Unitholder on whom a restriction is imposed and (ii) the restrictions set forth in this Section 2.10 shall not apply to any Registrable Securities that are included in such
Underwritten Offering by such Holder.
