 2. Registration. 

(a) Demand Registration Rights. 

(i) Any Holder that holds Registrable Securities (the “Initiating Holder”) shall have the option and right, exercisable by
delivering a written notice to the Partnership (a “Demand Notice”), to require the Partnership to, pursuant to the terms of and subject to the limitations contained in this Agreement, prepare and file with the Commission a
Registration Statement registering the offering and sale of all or any portion of such Holder’s Registrable Securities, which may, at the option of the Initiating Holder, be a Shelf Registration Statement (the “Demand
Registration”). 
 (ii) Within 15 Business Days of the receipt of the Demand Notice, the Partnership shall give written notice of
such Demand Notice to all other Holders that hold the same class of securities as the Registrable Securities and shall, subject to the limitations of this Section 2(a), use reasonable best efforts to file a Registration Statement covering all
of the Registrable Securities that such Holders shall in writing request (such request to be given to the Partnership within ten Business Days of written receipt of such notice of the Demand Notice given by the Partnership pursuant to this Section
2(a)(ii)) to be included in such Demand Registration as promptly as reasonably practicable as directed by the Initiating Holder in accordance with the terms and conditions of the Demand Notice and use reasonable best efforts to cause such
Registration Statement to become effective under the Securities Act and remain effective under the Securities Act for not less than six months following the Effective Date or such longer period ending when all Registrable Securities covered by such
Registration Statement have been sold (the “Effectiveness Period”). 
 (iii) Subject to the other limitations contained in
this Agreement, the Partnership shall not be obligated hereunder to effect more than five Demand Registrations pursuant to Section 2(a)(i). 

(iv) Notwithstanding any other provision of this Section 2(a), the Partnership shall not be required to effect a registration or file a
Registration Statement pursuant to this Section 2(a): (A) during the period starting with notice to the Holder of the intent to file a Registration Statement under Sections 2(a)(ii) or 2(b)(i) (which shall occur no earlier than 60 days
prior to a good faith estimate, with the approval of the Board of Directors, of the date of filing of such Registration Statement) and ending on a date 90 days after the effective date of, a Partnership-initiated registration; provided that
the Partnership uses reasonable best efforts to cause such registration statement to become effective; (B) for a period of up to 90 days after the date of a Demand Notice for registration pursuant to this Section 2(a) if at the time of
such request the Partnership is currently engaged in a self-tender or exchange offer and the filing of a Registration Statement would cause a violation of the Exchange Act; (C) for a period of up to 90 days, if the Conflicts Committee,
proceeding in good faith, determines that the filing of a Registration Statement would require an Adverse Disclosure; (D) if the anticipated aggregate offering price of all Registrable Securities requested to be registered or offered by the
Initiating Holder is less than $20 million; (E) for the duration of any Blackout Period, following its delivery of written notice thereof to the Holders or (F) if, in the Partnership’s good faith judgment, it is not feasible for the
Partnership to effect a registration or file a Registration Statement because audited or pro forma financial statements that are required by the Securities Act to be included in any related registration statement or prospectus are then unavailable,
until 

  
 6 








 
such time as such financial statements are completed or obtained by the Partnership, provided that the Partnership shall use its reasonable best efforts to complete or obtain such financial
statements as promptly as reasonably practicable; provided, that, in such event, the Holders requesting such Demand Registration may withdraw such request and, if withdrawn, such request will not count as one of the permitted Demand
Registrations hereunder and the Partnership will pay all expenses (including reasonable attorneys fees) in connection with such registrations; provided, further, that the Partnership may delay a Demand Registration hereunder only once in any
12-month period. 
 (v) Notwithstanding any other provision of this Section 2(a), if (A) the Holders intend to distribute the
Registrable Securities covered by a Demand Registration by means of an underwritten public offering and (B) the managing underwriter or managing underwriters of such offering advise the Partnership in writing that, in their opinion, the
inclusion of all of such Holders’ Registrable Securities and all securities (“Other Registrable Securities”) of any other Persons who have been granted applicable registration rights (the “Other Holders”) in
the subject Registration Statement would have a material adverse effect on the marketability of the offering, then the Partnership shall so advise all Holders of such Registrable Securities and Other Holders of Other Registrable Securities that
would otherwise be underwritten pursuant hereto, and the number of such securities that may be included in the underwriting shall be reduced to equal the number of such securities that such managing underwriter or managing underwriters advise the
Partnership can be sold without having such material adverse effect. The aggregate number of such securities to be included in such Demand Registration as a result of the reduction described in the immediately preceding sentence shall be allocated
(I) first, to the extent applicable, in accordance with the Existing Registration Rights Agreement, (II) second, among the Holders and the Parity Holders not a party to the Existing Registration Rights Agreement seeking to include such securities in
the underwriting, with each such holder being reduced pro rata, based on the percentage derived by dividing (x) the number of such securities owned by such holder by (y) the total number of such securities owned by such holders seeking to
include such securities in the underwriting and (III) third, among the Other Holders not included in (I) or (II) above seeking to include such securities in the underwriting, with each such holder being reduced pro rata, based on the percentage
derived by dividing (x) the number of such securities owned by such holder by (y) the total number of such securities owned by such holders seeking to include such securities in the underwriting. Any Registrable Securities excluded or
withdrawn from such underwriting shall be withdrawn from the registration. 
 (vi) The Partnership may include in any such Demand
Registration other Partnership securities for sale for its own account or for other Holders as provided herein; provided that if the managing underwriter for the offering determines that the number of securities proposed to be offered in such
offering would have a material adverse effect on the marketability of such offering, then the Registrable Securities to be sold by the Holders shall be included in such registration before any Partnership securities proposed to be sold for the
account of the Partnership or any other Person. 
 (vii) Subject to the limitations contained in this Agreement, the Partnership shall
effect any Demand Registration on Form S-3 (except if the Partnership is not then eligible to register for resale the Registrable Securities on Form S-3, in which case such Demand Registration shall be effected on another appropriate form for such
purpose pursuant to the 

  
 7 








 
Securities Act) and if the Partnership is at the time of its receipt of a Demand Notice a WKSI, the Demand Registration for any offering and selling of Registrable Securities through a firm
commitment underwriting shall be effected pursuant to an Automatic Shelf Registration Statement, which shall be on Form S-3 or any equivalent or successor form under the Securities Act (if available to the Partnership). 

(viii) Without limiting Section 3, in connection with any Demand Registration pursuant to and in accordance with this Section 2(a),
the Partnership shall (A) promptly prepare and file or cause to be prepared and filed: (1) such additional forms, amendments, supplements, prospectuses, certificates, letters, opinions and other documents, as may be necessary or advisable
to register or qualify the securities subject to such Demand Registration, including under the securities laws of such states as the Holders shall reasonably request; provided, however, that no such qualification shall be required in
any jurisdiction where, as a result thereof, the Partnership would become subject to general service of process or to taxation or qualification to do business in such jurisdiction solely as a result of registration and (2) such forms,
supplements, prospectuses, certificates, letters, opinions and other documents as may be necessary to apply for listing or to list the Registrable Securities subject to such Demand Registration on the Trading Market and (B) do any and all other
acts and things that may be necessary or appropriate or reasonably requested by the Holders to enable the Holders to consummate a public sale of such Registrable Securities in accordance with the intended timing and method or methods of distribution
thereof. 
 (ix) In the event a Holder transfers Registrable Securities included on a Registration Statement and such Registrable Securities
remain Registrable Securities following such transfer, at the request of such Holder, the Partnership shall amend or supplement such Registration Statement or related Prospectus as may be necessary in order to enable such transferee to offer and
sell such Registrable Securities pursuant to such Registration Statement. 
 (b) Piggyback Registration. 

(i) If the Partnership shall at any time, following conversion of Series A Preferred Units, Series B Preferred Units or Other Preferred Units
into Common Units, propose to file a Registration Statement, other than pursuant to a Demand Registration, for an offering of Common Units for cash (whether in connection with a public offering of Common Units by the Partnership, a public offering
of Common Units by unitholders, or both, but excluding an offering relating solely to an employee benefit plan, an offering relating to a transaction on Form S-4 or an offering on any registration statement form that does not permit secondary
sales), the Partnership shall promptly notify all Holders of such proposal reasonably in advance of (and in any event at least ten Business Days before) the anticipated initial filing date of such Registration Statement (the “Common
Piggyback Notice”). The Common Piggyback Notice shall offer the Holders the opportunity to include for registration in such Registration Statement the number of Common Units constituting Registrable Securities as they may request (a
“Common Piggyback Registration”). The Partnership shall use reasonable best efforts to include in each such Common Piggyback Registration such Common Units constituting Registrable Securities for which the Partnership has received
written requests within five Business Days after mailing of the Common Piggyback Notice (“Common Piggyback Request”) for inclusion therein. If a Holder decides not to include all of its Common Units constituting Registrable
Securities in any 

  
 8 








 
Registration Statement thereafter filed by the Partnership, such Holder shall nevertheless continue to have the right to include any Registrable Securities in any subsequent registration
statement or registration statements as may be filed by the Partnership with respect to offerings of Common Units, all upon the terms and conditions set forth herein. 

(ii) If the Partnership shall at any time propose to file a Registration Statement, other than pursuant to a Demand Registration, for an
offering of Series A Preferred Units, Series B Preferred Units or Other Preferred Units for cash (whether in connection with a public offering of Series A Preferred Units, Series B Preferred Units or Other Preferred Units by the Partnership, a
public offering of Series A Preferred Units, Series B Preferred Units or Other Preferred Units by unitholders, or both, but excluding an offering relating solely to an employee benefit plan, an offering relating to a transaction on Form S-4 or an
offering on any registration statement form that does not permit secondary sales), the Partnership shall promptly notify all Holders of the applicable series of such proposal reasonably in advance of (and in any event at least ten Business Days
before) the anticipated initial filing date of such Registration Statement (the “Preferred Piggyback Notice”). The Preferred Piggyback Notice shall offer such Holders the opportunity to include for registration in such Registration
Statement the number of Series A Preferred Units, Series B Preferred Units or Other Preferred Units, as applicable, constituting Registrable Securities as they may request (a “Preferred Piggyback Registration”). The Partnership
shall use reasonable best efforts to include in each such Preferred Piggyback Registration such Series A Preferred Units, Series B Preferred Units or Other Preferred Units, as applicable, constituting Registrable Securities for which the Partnership
has received written requests within five Business Days after mailing of the Preferred Piggyback Notice (“Preferred Piggyback Request”) for inclusion therein. If a Holder decides not to include all of its Series A Preferred Units,
Series B Preferred Units or Other Preferred Units, as applicable, constituting Registrable Securities in any Registration Statement thereafter filed by the Partnership for the series being so registered, such Holder shall nevertheless continue to
have the right to include such Registrable Securities in any subsequent registration statement or registration statements as may be filed by the Partnership with respect to offerings of Series A Preferred Units, Series B Preferred Units or Other
Preferred Units, as applicable, all upon the terms and conditions set forth herein. 
 (iii) If the Registration Statement under which the
Partnership gives notice under this Section 2(b) is for an underwritten offering, the Partnership shall so advise the applicable Holders of Registrable Securities. In such event, the right of any Holder to be included in a registration
pursuant to this Section 2(b) shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s applicable Registrable Securities in the underwriting to the extent provided herein. If the
managing underwriter or managing underwriters of such offering advise the Partnership that, in their opinion, the inclusion of all of such Holders’ applicable Registrable Securities and all the Other Holders’ applicable Other Registrable
Securities in the subject Registration Statement would have a material adverse effect on the marketability of the offering, then the Partnership shall so advise all Holders of applicable Registrable Securities and Other Holders of applicable Other
Registrable Securities that would otherwise be underwritten pursuant hereto, and the number of such securities that may be included in the underwriting shall be reduced to equal the number of such securities that such managing underwriter or
managing underwriters advise the Partnership can be sold without having such material adverse effect. The aggregate number of such 

  
 9 








 
securities to be included in such Piggyback Registration as a result of the reduction described in the immediately preceding sentence shall be allocated (I) first, to the extent applicable, in
accordance with the Existing Registration Rights Agreement, (II) second, among the Holders and the Parity Holders not a party to the Existing Registration Rights Agreement seeking to include such securities in the underwriting, with each such holder
being reduced pro rata, based on the percentage derived by dividing (x) the number of such securities owned by such holder by (y) the total number of such securities owned by such holders seeking to include such securities in the
underwriting and (III) third, among the Other Holders not included in (I) or (II) above seeking to include such securities in the underwriting, with each such holder being reduced pro rata, based on the percentage derived by dividing (x) the
number of such securities owned by such holder by (y) the total number of such securities owned by such holders seeking to include such securities in the underwriting. If any Holder disapproves of the terms of any such underwriting, such Holder
may elect to withdraw therefrom by written notice to the Partnership and the managing underwriter(s) delivered on or prior to the time of pricing of such offering. For the avoidance of doubt, the securities to be sold for the account of the
Partnership pursuant to this Section 2(b) shall be included in such underwriting before any Registrable Securities to be sold by any Holders or any other Person. Any Registrable Securities excluded or withdrawn from such underwriting shall be
withdrawn from the registration. 
 (iv) The Partnership shall have the right to terminate or withdraw any registration initiated by it
under this Section 2(b) prior to the Effective Date of such Registration Statement whether or not any Holder has elected to include Registrable Securities in such Registration Statement. The registration expenses of such withdrawn
registration (including reasonable attorneys fees of the Holders that elected to include Registrable Securities in such Registration Statement) shall be borne by the Partnership in accordance with Section 4 hereof. 

(c) General Provisions. 

(i) All registration rights granted under this Section 2 shall continue to be applicable with respect to any Holder for so long as may be
required for each such Holder to sell all of the Registrable Securities held by such Holder as provided in this Agreement. 
 (ii) Any
Demand Notice or Piggyback Request shall (i) specify the Registrable Securities intended to be offered and sold by the Holder making the request, (ii) express such Holder’s present intent to offer such Registrable Securities for
distribution, (iii) describe the nature or method of the proposed offer and sale of Registrable Securities, and (iv) contain the undertaking of such Holder to provide all such information and materials and take all action as may reasonably
be required in order to permit the Partnership to comply with all applicable requirements in connection with the registration of such Registrable Securities. 

(iii) Other than the Existing Registration Rights Agreement, the Partnership has not entered into any agreement which (a) conflicts with the
provisions hereof in any material respect or (b) would allow any Holder to include Registrable Securities in any Registration Statement filed by the Partnership on a basis that is superior or more favorable in any material respect to the rights
granted to the Holders hereunder. 

  
 10 








 (iv) Notwithstanding any provision of this Agreement to the contrary, the Partnership may
voluntarily suspend the effectiveness of any Shelf Registration Statement or may otherwise require the discontinuance of offers under the Shelf Registration Statement for a period of up to 90 days if the Conflicts Committee, proceeding in good
faith, determines the offering of any Registrable Securities pursuant to such Shelf Registration Statement would require an Adverse Disclosure (a “Suspension”); provided, however, that in no event shall the Partnership effect
Suspensions under this Section 2(c)(iii) for more than an aggregate of 90 days in any 12-month period. The Partnership shall notify each Holder eligible to sell Registrable Securities under such
Shelf Registration Statement promptly of any Suspensions and, upon receipt of such notice, each such Holder shall forthwith discontinue disposition of such Registrable Securities under such Shelf Registration Statement until such Holder’s
receipt of the copies of the supplemental Prospectus or amended Shelf Registration Statement or until it is advised in writing by the Partnership that the use of the applicable Prospectus may be resumed, and, in either case, has received copies of
any additional or supplemental filings that are incorporated or deemed to be incorporated by reference in such Shelf Registration Statement. In addition, the Partnership shall promptly notify each Holder of the termination or lifting of any such
Suspension. 
 3. Registration Procedures. The procedures to be followed by the Partnership and each Holder electing to sell
Registrable Securities included in a Registration Statement pursuant to this Agreement, and the respective rights and obligations of the Partnership and such Holders, with respect to the preparation, filing and effectiveness of such Registration
Statement, are as follows: 
 (a) The Partnership will, at least five Business Days prior to the anticipated filing of a Registration
Statement or any related Prospectus or any amendment or supplement thereto (other than amendments and supplements filed principally for the purpose of naming Holders and providing information with respect thereto), (i) furnish to such Holders copies
of all such documents proposed to be filed and (ii) give good faith consideration to such comments as any Holder reasonably shall propose. 

(b) The Partnership will use reasonable best efforts to (i) prepare and file with the Commission such amendments, including
post-effective amendments, and supplements to each Registration Statement and the Prospectus used in connection therewith as may be necessary under applicable law to keep such Registration Statement continuously effective with respect to the
disposition of all Registrable Securities covered thereby for its Effectiveness Period and, subject to the limitations contained in this Agreement, prepare and file with the Commission such additional Registration Statements in order to register for
resale under the Securities Act all of the Registrable Securities held by the applicable Holders; (ii) cause the related Prospectus to be amended or supplemented by any required prospectus supplement, and as so supplemented or amended to be
filed pursuant to Rule 424; and (iii) respond to any comments received from the Commission with respect to each Registration Statement or any amendment thereto and provide such Holders true and complete copies of all correspondence from
and to the Commission relating to such Registration Statement that pertains to such Holders as Selling Holders. 

  
 11 








 (c) The Partnership will comply in all material respects with the provisions of the Securities
Act and the Exchange Act with respect to the Registration Statements and the disposition of all Registrable Securities covered by each Registration Statement. 

(d) The Partnership will use reasonable best efforts to notify such Holders promptly: (i)(A) when the Commission notifies the Partnership
whether there will be a “review” of such Registration Statement and whenever the Commission comments in writing on such Registration Statement (in which case the Partnership shall provide true and complete copies thereof and all written
responses thereto to each of such Holders and in good faith consider such Holder’s comments in the Registration Statement); and (B) with respect to each Registration Statement or any post-effective amendment thereto, when the same has been
declared effective; (ii) of any request by the Commission or any other federal or state governmental authority for amendments or supplements to a Registration Statement or Prospectus or for additional information that pertains to such Holders
as sellers of Registrable Securities; (iii) of the issuance by the Commission of any stop order suspending the effectiveness of a Registration Statement covering any or all of the Registrable Securities or the initiation of any Proceedings for
that purpose; (iv) of the receipt by the Partnership of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction, or the initiation or
threatening of any Proceeding for such purpose; and (v) of the occurrence of (but not the nature or details concerning) any event or passage of time that makes any statement made in such Registration Statement or Prospectus or any document
incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires any revisions to such Registration Statement, Prospectus or other documents so that, in the case of such Registration Statement or the
Prospectus, as the case may be, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which
they were made, not misleading (provided, however, that no notice by the Partnership shall be required pursuant to this clause (v) in the event that the Partnership either promptly files a prospectus supplement to update the Prospectus or a
Form 8-K or other appropriate Exchange Act report that is incorporated by reference into the Registration Statement, which in either case, contains the requisite information that results in such Registration Statement no longer containing any untrue
statement of material fact or omitting to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading). 

(e) The Partnership will use reasonable best efforts to avoid the issuance of, or, if issued, obtain the withdrawal of (i) any order
suspending the effectiveness of a Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, at the earliest practicable time, or if
any such order or suspension is made effective during any Suspension period, at the earliest practicable time after the Suspension period is over. 

(f) During the Effectiveness Period, the Partnership will furnish to each such Holder, without charge, at least one conformed copy of each
Registration Statement and each amendment thereto and all exhibits to the extent requested by such Holder (including those incorporated by reference) promptly after the filing of such documents with the Commission; provided, that the
Partnership will not have any obligation to provide any document pursuant to this clause that is available on the Commission’s EDGAR system. 

  
 12 








 (g) The Partnership will promptly deliver to each Holder, without charge, as many copies of each
Prospectus or Prospectuses (including each form of Prospectus) and each amendment or supplement thereto as such Holder may reasonably request during the Effectiveness Period. The Partnership consents to the use of such Prospectus and each
amendment or supplement thereto by each of the Selling Holders in connection with the offering and sale of the Registrable Securities covered by such Prospectus and any amendment or supplement thereto. 

(h) Upon written notice by a Holder to the Partnership, the Partnership will use reasonable best efforts to cause all Registrable Securities
registered pursuant to this Agreement to be listed on the Trading Market and will use reasonable best efforts to provide a transfer agent and registrar for Registrable Securities covered by a Registration Statement not later than the Effective Date
of such Registration Statement and for as long as Registrable Securities covered by a Registration Statement remain outstanding. 
 (i) The
Partnership will cooperate with such Holders to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be delivered to a transferee pursuant to a Registration Statement, which certificates shall be free
of all restrictive legends indicating that the Registrable Securities are unregistered or unqualified for resale under the Securities Act, Exchange Act or other applicable securities laws, and to enable such Registrable Securities to be in such
denominations and registered in such names as any such Holder may request in writing. 
 (j) Upon the occurrence of any event contemplated
by Section 3(d)(v), as promptly as reasonably possible, the Partnership will prepare a supplement or amendment, including a post-effective amendment, if required by applicable law, to the affected Registration Statement or a supplement to the
related Prospectus or any document incorporated or deemed to be incorporated therein by reference, and file any other required document so that, as thereafter delivered, no Registration Statement nor any Prospectus will 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, in the light of the circumstances under which they were made, not misleading. 

(k) Such Holders may distribute the Registrable Securities by means of an underwritten offering; provided that (i) such Holders
provide written notice to the Partnership of their intention to distribute Registrable Securities by means of an underwritten offering, (ii) the right of any Holder to include such Holder’s Registrable Securities in such registration shall
be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein, (iii) the managing underwriter or managing underwriters
thereof shall be subject to the approval of the Partnership (which shall not be unreasonably withheld), (iv) each Holder participating in such underwritten offering agrees to enter into an underwriting agreement in customary form and sell such
Holder’s Registrable Securities on the basis provided in any reasonable underwriting arrangements approved by the Partnership and (v) each Holder participating in such underwritten 

  
 13 








 
offering completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably and customarily required under the terms of such
underwriting arrangements, provided, that, no Holder included in any underwritten registration shall be required to make any representations or warranties to the Partnership or the underwriters (other than representations and warranties regarding
such Holder) or to undertake any indemnification obligations to the Partnership or the underwriters except as provided in Section 5. The Partnership hereby agrees with each Holder that, in connection with any underwritten offering in accordance
with the terms hereof, it will negotiate in good faith and execute all indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements, including using reasonable best efforts to procure
customary legal opinions and auditor “comfort” letters. 
 (l) In the event such Holders seek to complete an underwritten
offering, for a reasonable period prior to the filing of any Registration Statement and throughout the Effectiveness Period, the Partnership will make available upon reasonable notice at the Partnership’s principal place of business or such
other reasonable place for inspection by the Selling Holder and the managing underwriter or managing underwriters selected in accordance with Section 3(k) such financial and other information and books and records of the Partnership, and cause
the officers, employees, counsel and independent certified public accountants of the Partnership to respond to such inquiries, as shall be reasonably necessary (and in the case of counsel, not violate an attorney-client privilege in such
counsel’s reasonable belief) to conduct a reasonable investigation within the meaning of Section 11 of the Securities Act. 
 (m)
In connection with any registration of Registrable Securities pursuant to this Agreement, the Partnership will take such reasonable best actions as are necessary or advisable in order to expedite or facilitate the disposition of Registrable
Securities by such Holders, including using reasonable best efforts to cause appropriate officers and employees to be available, on a customary basis and upon reasonable notice, to meet with prospective investors in presentations, meetings and road
shows. 
 (n) The Partnership will have no obligation to include in a Registration Statement or Piggyback Registration Registrable
Securities of a Holder who has failed to timely furnish such information requested in writing by the Partnership no less than 10 days prior to the effective date of the Registration Statement, which, in the opinion of counsel to the Partnership, is
reasonably required in order for the Registration Statement or related Prospectus to comply with the Securities Act, provided that if the Registration Statement is not yet effective, the Partnership agrees to amend the Registration Statement to
include the Registrable Securities of a Holder when such information is provided. 
 (o) In connection with any underwritten offering, each
Holder hereby agrees that such Holder shall enter into a standard lock-up agreement covering such Registrable Securities and for a period specified by the managing underwriter or managing underwriters (the “Lock-Up Period”). In
addition, if (A) during the last 17 days of the Lock-Up Period, the Partnership issues an earnings release or material news or a material event relating to the Partnership occurs or (B) prior to the expiration of the Lock-Up Period, the
Partnership announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-Up Period, then the restrictions imposed by this Section 3(o) shall continue to apply


  
 14 








 
until the expiration of the 18-day period beginning on the issuance of the earnings release or the announcement of the material news or the occurrence of the material event. Each Holder
agrees to execute and deliver such other agreements as may be reasonably requested by the Partnership or the underwriter which are consistent with the foregoing or which are necessary to give further effect thereto. In addition, if requested by
the Partnership or the representative of the underwriters of Series A Preferred Units, Series B Preferred Units, Other Preferred Units or Common Units issued upon conversion of Series A Preferred Units, Series B Preferred Units or Other Preferred
Units, each Holder shall provide, within five Business Days of such request, such information as may be reasonably and customarily required by the Partnership or such representative in connection with the completion of any public offering of the
Series A Preferred Units, Series B Preferred Units, Other Preferred Units or Common Units issued upon conversion of Series A Preferred Units, Series B Preferred Units or Other Preferred Units pursuant to a Registration Statement, unless such Holder
reasonably believes that such information constitutes material and non-public information or such Holder is otherwise subject to confidentiality obligations with respect to the requested information. The obligations described in this
Section 3(o) shall not apply to a registration relating solely to employee benefit plans on Form S-1 or Form S-8 or similar forms that may be promulgated in the future, or a registration relating solely to a transaction on Form S-4 or similar
forms that may be promulgated in the future. The Partnership may impose stop-transfer instructions with respect to the Series A Preferred Units, Series B Preferred Units, Other Preferred Units or Common Units issued upon conversion of Series A
Preferred Units, Series B Preferred Units or Other Preferred Units subject to the foregoing restriction until the end of the Lock-Up Period. 

(p) The Partnership will use its reasonable best efforts to comply with the securities laws of the United States and other applicable
jurisdictions and all applicable rules and regulations of the Commission and comparable governmental agencies in other applicable jurisdictions and make generally available to the Holders, in each case as soon as practicable after the Effective Date
(it being understood that the Partnership shall have until at least 410 days or, if the fourth quarter following the fiscal quarter that includes the Effective Date is the last fiscal quarter of the Partnership’s fiscal year, 455 days after the
end of the Partnership’s then-current fiscal quarter), an earnings statement of the Partnership (which need not be audited) complying with the provisions of Section 11(a) of the Securities Act (including, at the option of the Partnership, Rule
158). 
 4. Registration Expenses. All Registration Expenses incident to the Parties’ performance of or compliance with
their respective obligations under this Agreement or otherwise in connection with any Demand Registration or Piggyback Registration (excluding any Selling Expenses) shall be borne by the Partnership, whether or not any Registrable Securities are
sold pursuant to a Registration Statement. “Registration Expenses” shall include, without limitation, (i) all registration and filing fees (including fees and expenses (A) with respect to filings required to be made with
the Trading Market, (B) in connection with any filings required to be made with the Financial Industry Regulatory Authority, Inc. and (C) in compliance with applicable state securities or “Blue Sky” laws), (ii) printing expenses
(including expenses of printing certificates for Series A Preferred Units, Series B Preferred Units, Other Preferred Units or Common Units issued upon conversion of Series A Preferred Units, Series B Preferred Units or Other Preferred Units and of


  
 15 








 
printing prospectuses if the printing of prospectuses is reasonably requested by a Holder included in the Registration Statement), (iii) messenger, telephone and delivery expenses,
(iv) fees and expenses of counsel (including local and special), auditors and accountants (including the expenses of any “cold comfort” letters required or incidental to the performance of such obligations) for the Partnership,
(v) Securities Act liability insurance, if the Partnership so desires such insurance, (vi) fees and expenses of all other Persons retained by the Partnership in connection with the consummation of the transactions contemplated by this
Agreement, (vii) the costs and expenses related to investor presentations on any road show undertaken in connection with the marketing of the Series A Preferred Units, Series B Preferred Units, Other Preferred Units or Common Units issued upon
conversion of Series A Preferred Units, Series B Preferred Units or Other Preferred Units, including, expenses associated with any electronic road show, travel and lodging expenses of the officers and employees of the General Partner or any Group
Member, (viii) the costs and expenses of qualifying the Series A Preferred Units, Series B Preferred Units, Other Preferred Units or Common Units issued upon conversion of Series A Preferred Units, Series B Preferred Units or Other Preferred
Units for inclusion in the book-entry settlement system of the DTC and (ix) the fees and expenses of the transfer agent and registrar. Except as provided herein, all Selling Expenses shall be borne by the Selling Holders pro rata in proportion
to the number of Registrable Securities sold by each Selling Holder or as they may otherwise agree. 
 5.
Indemnification. 
 (a) By the Partnership. If underwriters are engaged in connection with any registration
referred to in Section 2, the Partnership shall provide indemnification, representations, covenants, opinions and other assurances to the underwriters in form and substance reasonably satisfactory to such underwriters and the Partnership. In
the event of a registration of any Registrable Securities under the Securities Act pursuant to this Agreement, in addition to and not in limitation of the Partnership’s obligations under Section 7.7 of the Partnership Agreement, to the
fullest extent permitted by applicable law, the Partnership shall indemnify and hold harmless each Selling Holder, its officers, directors and each Person who controls the Holder (within the meaning of the Securities Act), and any agent thereof
(collectively, “Indemnified Persons”) from and against any and all losses, claims, damages, liabilities, joint or several, expenses (including legal fees and expenses), judgments, fines, penalties, interest, settlements or other
amounts arising from any and all claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, in which any Indemnified Person may be involved, or is threatened to be involved, as a party or otherwise,
under the Securities Act or otherwise (collectively, “Losses”), based upon, arising out of or resulting from any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, preliminary
prospectus, final prospectus or issuer free writing prospectus under which any Registrable Securities were registered or sold by such Selling Holder under the Securities Act, or arising out of, based upon or resulting from the omission or alleged
omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; provided, however, that the Partnership shall not be liable to any Indemnified Person to the extent that any
such Loss arises out of, is based upon or results from an untrue statement or alleged untrue statement or omission or alleged omission so made in 

  
 16 








 
such Registration Statement, preliminary prospectus, final prospectus or issuer free writing prospectus in reliance upon or in conformity with written information furnished to the Partnership by
or on behalf of such Selling Holder specifically for use in the preparation thereof. 
 (b) By Each Selling Holder. Each Selling
Holder agrees, to the fullest extent permitted by law, to severally and not jointly, indemnify and hold harmless the Partnership, the General Partner’s officers and its directors and each Person who controls the Partnership (within the meaning
of the Securities Act) and any agent thereof 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 such Registration Statement, preliminary prospectus, final prospectus or free writing prospectus and any indemnification hereunder will be limited to the amount of net proceeds received from the sale of
Registrable Securities by such Holder under such Registration Statement. 
 6. Facilitation of Sales Pursuant to Rule
144. Upon effectiveness of a Registration Statement with the Commission, the Partnership shall use reasonable best efforts to timely file the reports required to be filed by it under the Exchange Act or the Securities Act (including the
reports under Sections 13 and 15(d) of the Exchange Act referred to in subparagraph (c)(1) of Rule 144), and take such further action as any Holder may reasonably request, all to the extent required from time to time to enable the Holders to sell
Registrable Securities without registration under the Securities Act within the limitations of the exemption provided by Rule 144. 
 7.
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 (other than (i) current or future Parity Holders and (ii) future holders of Common Units who are issued such Common Units in future private placement transactions (such holders,
“New Common Unit Holders”)) that would allow such holder to require the Partnership to include securities in any registration statement filed by the Partnership on a basis that is senior in any way to the registration rights granted to the
Initial Holder hereunder; provided that any such agreements with New Common Unit Holders may only grant such New Common Unit Holders, in the aggregate, two demand registration rights that are superior to the registration rights granted to the
Initial Holder hereunder and only with respect to Common Units, and any demand registration rights of such New Common Unit Holders, in the aggregate, in excess of such two demand registration rights shall be subject to the limitation in this Section
7. For the avoidance of doubt, any registration rights granted to such New Common Unit Holders that are senior to the registration rights granted to the Initial Holder hereunder shall only apply with respect to the Common Units issuable upon
conversion of Series A Preferred Units, Series B Preferred Units or Other Preferred Units. 

  
 17 








 8. Miscellaneous. 

(a) Discontinued Disposition. Each Holder agrees by its acquisition of such Registrable Securities that, upon receipt of a notice
from the Partnership of the occurrence of any event of the kind described in clauses (ii) through (v) of Section 3(d), such Holder shall forthwith discontinue disposition of such Registrable Securities under the Registration Statement until
such Holder’s receipt of the copies of the supplemental Prospectus or amended Registration Statement or until it is advised in writing by the Partnership that the use of the applicable Prospectus may be resumed, and, in either case, has
received copies of any additional or supplemental filings that are incorporated or deemed to be incorporated by reference in such Prospectus or Registration Statement. The Partnership may provide appropriate stop orders to enforce the provisions of
this Section 8(a). 
 (b) Recapitalization, Exchanges, etc. Affecting the Series A Preferred Units, Series B Preferred Units, Other
Preferred Units and the Common Units. The provisions of this Agreement shall apply to the full extent set forth herein with respect to any and all Partnership Interests 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 Registrable Securities, including any equity securities that may be issued in exchange for Registrable Securities in connection
with any merger, consolidation or other business combination involving the Partnership and any of its subsidiaries, and shall be appropriately adjusted for combinations, recapitalizations and the like occurring after the date of this
Agreement. The Partnership will not take any action, or permit any change to occur, with respect to the terms of its securities that would materially and adversely affect the ability of the Holders to include Registrable Securities in a
registration undertaken pursuant to this Agreement or that would adversely affect the marketability of such Registrable Securities in any such registration. 

(c) Change of Control. The Partnership shall not merge, consolidate or combine with any other Person unless the agreement providing for
such merger, consolidation or combination expressly provides for the continuation of the registration rights specified in this Agreement with respect to the Registrable Securities or other equity securities issued pursuant to such merger,
consolidation or combination. 
 (d) Specific Performance. Damages in the event of breach of this Agreement by a Party may be
difficult, if not impossible, to ascertain, and it is therefore agreed that each such Party, in addition to and without limiting any other remedy or right it may have, will have the right to an injunction or other equitable relief in any court of
competent jurisdiction, enjoining any such breach, and enforcing specifically the terms and provisions hereof, and each of the Parties hereby waives any and all defenses it may have on the ground of lack of jurisdiction or competence of the court to
grant such an injunction or other equitable relief (including the requirement to post bond). The existence of this right will not preclude any such Party from pursuing any other rights and remedies at law or in equity which such Party may have.

 (e) Amendments. This Agreement may be amended only by means of a written amendment signed by (i) the Partnership and
(ii) the Holders of 66  2⁄3% of the then-outstanding Registrable Securities; provided, however, that no such amendment shall adversely
affect the rights of any Holder hereunder without the consent of such Holder. 

  
 18 








 (f) Notices. All notices, demands, requests and other communications required or
permitted to be given or made under this Agreement shall be in writing and shall be deemed given or made when delivered in person or when sent by first class United States mail or by other means of written communication to the Person at the address

 (g)
Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the Parties hereto and their heirs, executors, administrators, successors, legal representatives and permitted assigns. Except as provided in
this Section 8(g), this Agreement, and any rights or obligations hereunder, may not be assigned without the prior written consent of the Partnership and the Holders. Notwithstanding anything in the foregoing to the contrary, the registration
rights of a Holder pursuant to this Agreement with respect to all or any portion of its Registrable Securities may be assigned without such consent (but only with all related obligations) with respect to such Registrable Securities (and any
Registrable Securities issued as a dividend or other distribution with respect to, in exchange for or in replacement of such Registrable Securities) by such Holder to a transferee of such Registrable Securities; provided (i) the transfer
of the underlying Registrable Securities was made in accordance with the terms of the Partnership Agreement; (ii) the Partnership is, promptly after such transfer, furnished with written notice of the name, mailing address and email address of
such transferee or assignee and the Registrable Securities with respect to which such registration rights are being assigned; and (iii) such transferee or assignee agrees in writing to be bound by and subject to the terms set forth in this
Agreement. The Partnership may not assign its respective rights or obligations hereunder without the prior written consent of each of the Holders. 

  
 19 








 (h) Counterparts. This Agreement may be executed in counterparts, all of which
together shall constitute an agreement binding on all the Parties, notwithstanding that all such Parties are not signatories to the original or the same counterpart. Each Party shall become bound by this Agreement immediately upon affixing its
signature hereto. 
 (i) Applicable Law; Forum, Venue and Jurisdiction. This Agreement shall be construed in accordance with and
governed by the laws of the State of Delaware without regard to the principles of conflicts of law that would request an application of another state’s laws. Each of the Parties: 

(i) irrevocably agrees that any claims, suits, actions or proceedings (A) arising out of or relating in any way to this
Agreement (including any claims, suits or actions to interpret, apply or enforce the provisions of this Agreement or the duties, obligations or liabilities among the Parties, or the rights or powers of, or restrictions on, the Parties) or (B)
asserting a claim arising pursuant to any provision of the Delaware Act shall be exclusively brought in the Court of Chancery of the State of Delaware (or, if such court does not have subject matter jurisdiction, any other court located in the State
of Delaware with subject matter jurisdiction), in each case regardless of whether such claims, suits, actions or proceedings sound in contract, tort, fraud or otherwise, are based on common law, statutory, equitable, legal or other grounds, or are
derivative or direct claims; 
 (ii) irrevocably submits to the exclusive jurisdiction of such courts in connection with any
such claim, suit, action or proceeding; 
 (iii) agrees not to, and waives any right to, assert in any such claim, suit,
action or proceeding that (A) it is not personally subject to the jurisdiction of such courts or of any other court to which proceedings in such courts may be appealed, (B) such claim, suit, action or proceeding is brought in an inconvenient
forum, or (C) the venue of such claim, suit, action or proceeding is improper; 
 (iv) expressly waives any requirement for
the posting of a bond by a party bringing such claim, suit, action or proceeding; and 
 (v) consents to process being served
in any such claim, suit, action or proceeding by mailing, certified mail, return receipt requested, a copy thereof to such party at the address in effect for notices hereunder, and agrees that such services shall constitute good and sufficient
service of process and notice thereof; provided, nothing in clause (v) hereof shall affect or limit any right to serve process in any other manner permitted by law. 

(j) Cumulative Remedies. The remedies provided herein are cumulative and not exclusive of any remedies provided by law. 

  
 20 








 (k) Invalidity of Provisions. If any provision or part of a provision of this
Agreement is or becomes for any reason, invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions and/or parts thereof contained herein shall not be affected thereby and this Agreement
shall, to the fullest extent permitted by law, be reformed and construed as if such invalid, illegal or unenforceable provision, or part of a provision, had never been contained herein, and such provisions and/or part shall be reformed so that it
would be valid, legal and enforceable to the maximum extent possible. 
 (l) Facsimile Signatures. The use of facsimile or
electronic signatures affixed in the name and on behalf of the Party executing is expressly permitted by this Agreement. 
 (m) Entire
Agreement. This Agreement, together with the other Transaction Documents, constitute the entire agreement among the Parties with respect to the subject matter hereof and supersede all prior contracts or agreements with respect to the
subject matter hereof and the matters addressed or governed hereby or in the other Transaction Documents, whether oral or written. Without limiting the foregoing, each of the Parties acknowledges and agrees that (i) this Agreement is being
executed and delivered in connection with each of the other Transaction Documents and the transactions contemplated hereby and thereby, (ii) the performance of this Agreement and the other Transaction Documents and expected benefits herefrom
and therefrom are a material inducement to the willingness of the Parties to enter into and perform this Agreement and the other Transaction Documents and the transactions described herein and therein, (iii) the Parties would not have been
