Item 1.01. Entry into a Material Definitive Agreement

On April 21, 2016, NGL Energy Partners LP (the " Partnership ") entered into a Class A Convertible Preferred Unit and Warrant Purchase Agreement (the " Purchase Agreement ") with Highstar NGL Prism/IV-A Interco LLC and Highstar NGL Main Interco LLC (together, the “ Purchasers ”) to issue and sell to the Purchasers in a private placement (the " Private Placement ") an aggregate principal amount of $200 million of the Partnership’s 10.75% Class A Convertible Preferred Units (the “ Preferred Units ”) and warrants (the “ Warrants ”) that may be exercised to purchase common units representing limited partner interests in the Partnership (“ Common Units ”). The Purchasers are funds managed by Oaktree Capital Management L.P. (" Oaktree "). Oaktree will acquire approximately 16.6 million Preferred Units at a price of approximately $12.035 per Preferred Unit (the "Purchase Price") as well as approximately 3.6 million Warrants, which are subject to certain vesting and exercise terms described below. The Private Placement will be completed over the course of two closings, each of which is scheduled to occur prior to the end of June 2016. Both closings are subject to customary closing conditions. The Purchaser's obligation to fund the second closing is also contingent upon the receipt of certain funding commitments or the identification of an alternative co-investor reasonably satisfactory to it.

Each holder of Preferred Units (a “ Preferred Unit Holder ”) will be entitled to receive a cumulative, quarterly distribution in arrears at an annual rate of 10.75% on each Preferred Unit then held by such Preferred Unit Holder. At any time after the third anniversary of the initial closing date of the Private Placement (the “ Closing Date ”), each Preferred Unit Holder shall have the right, subject to certain conditions, to convert the Preferred Units then held by such Preferred Unit Holder, at the conversion rate then in effect, which may be settled in units, cash or a combination of each at the Partnership's election. At any time after the eighth anniversary of the Closing Date, the Partnership shall have the right to convert all of the outstanding Preferred Units into Common Units at the conversion rate then in effect, provided that the Partnership has paid in full all quarterly distributions on the outstanding Preferred Units and that certain conditions described in the Purchase Agreement have been satisfied. At any time after the first anniversary of the Closing Date, the Partnership shall have the right to redeem all of the outstanding Preferred Units at a price per Preferred Unit equal to the Purchase Price multiplied by the redemption multiple then in effect, as described in the Purchase Agreement. Upon a Change of Control (as defined in the Purchase Agreement) of the Partnership, each Preferred Unit Holder shall have the right, at its election, to either (i) require the Partnership to redeem the Preferred Units then held by such Preferred Unit Holder at a price per Preferred Unit equal to the Purchase Price multiplied by the change of control redemption multiple then in effect; (ii) if the Partnership is the surviving entity of such Change of Control, continue to hold Preferred Units; or (iii) convert all of the Preferred Units then held by such Preferred Unit Holder at the conversion rate then in effect. The Preferred Units will vote on an as-converted basis with the Common Units. Pursuant to the Purchase Agreement, on the Closing Date, the Partnership will enter into a registration rights agreement with the Purchasers, pursuant to which the Partnership shall agree to file a shelf registration statement registering the resale by the Purchasers of the Common Units to be issued upon conversion of the Preferred Units and exercise of the Warrants (as described below).

The Warrants will be exercisable for 3.5% of the total number of Common Units that are issued and outstanding immediately prior to the Closing Date, at an exercise price of $0.01 per Common Unit (subject to customary adjustments). The Warrants will not include anti-dilution adjustments for economic dilution, including any such economic dilution resulting from the issuance of Common Units below a particular price. Incidental to their ownership of the Warrants, the holders of the Warrants shall have preemptive rights (proportional to their Common Unit ownership on an as exercised basis) with respect to any issuance of Common Units by the Partnership, subject to certain exceptions including the issuance of Common Units pursuant to an at-the-market program , any employee benefit or compensation program, policy or arrangement, certain mergers and acquisitions, certain firm commitment public offerings, exercises of warrants or options and pursuant to any dividends, splits or other reclassifications. One-third of the Warrants may be exercised from and after the first anniversary of the Closing Date, another one-third of the Warrants may be exercised from and after the second anniversary of the Closing Date; and all Warrants shall be exercisable from and after the third anniversary of the Closing Date. Notwithstanding the foregoing, upon the occurrence of a Change of Control (as defined in the Purchase Agreement) or in the event the Partnership exercises its redemption right as described below with respect to the Preferred Units, all unvested Warrants shall immediately vest and be exercisable in full. Unexercised Warrants will expire on the eighth anniversary of the Closing Date. The Warrants will not participate in cash distributions by the Partnership.

Upon consummation of the second closing, the Private Placement will result in aggregate net proceeds to the Partnership of approximately $196 million, after deducting transaction fees and estimated offering expenses. The Partnership expects to use the net proceeds from the issuance of the Preferred Units to repay borrowings outstanding on its revolving credit facility, which may be re-borrowed in the future to fund capital expenditures and for other general partnership purposes.

The issuance of the Preferred Units pursuant to the Purchase Agreement is being made in reliance upon an exemption from the registration requirements of the Securities Act of 1933, as amended (the “ Securities Act ”), pursuant to Section 4(a)(2) thereof. The Purchase Agreement contains customary representations and warranties by Partnership and the Purchasers, and each party (an “ indemnifying party ”) has agreed to indemnify the other parties for losses resulting from the indemnifying party’s breach of any of its representations, warranties or covenants.

The Purchase Agreement is filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference. The above description of the material terms of the Purchase Agreement does not purport to be complete and is qualified in its entirety by reference to Exhibit 10.1.

On April 21, 2016, the Partnership issued a press release announcing the entry into the Purchase Agreement. A copy of the press release is attached as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.


Item 3.02	Unregistered Sales of Equity Securities

The information regarding the Private Placement set forth in Item 1.01 of this Current Report is incorporated by reference into this Item 3.02. The Private Placement of the Preferred Units pursuant to the Purchase Agreement will be undertaken in reliance upon an exemption from the registration requirements of the Securities Act pursuant to Section 4(a)(2) thereof.

Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim without the consent of the Indemnified Party, unless the settlement thereof imposes no liability or obligation on, involves no admission of wrongdoing or malfeasance by, and includes a complete release from liability of, the Indemnified Party.

(a) Notwithstanding anything herein to the contrary, this Agreement may be terminated at any time at or prior to the Initial Closing by the mutual written consent of the Partnership and the Purchasers entitled to purchase a majority of the Purchased Units on Initial Closing Date and the Warrants in accordance with Schedule A .

(b) Notwithstanding anything herein to the contrary, this Agreement shall automatically terminate at any time at or prior to the Initial 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 which permanently restrains, precludes, enjoins or otherwise prohibits the consummation of the transactions contemplated by this Agreement or makes the transactions contemplated by this Agreement illegal; or

(ii) if the Initial Closing shall not have occurred on or before May 30, 2016.

(c) Notwithstanding anything herein to the contrary, the Purchasers shall not be obligated to purchase, and the Partnership shall not be obligated to issue, Preferred Units on the Second Closing Date or Warrant Units on the Second Closing Date and all obligations of the parties with respect to a Second Closing Date shall terminate (without affecting the other terms of this Agreement):

(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 which permanently restrains, precludes, enjoins or otherwise prohibits the consummation of the transactions contemplated by this Agreement with respect to such purchase or issuance on the Second Closing Date or makes the transactions contemplated by this Agreement with respect to such purchase or issuance on the Second Closing Date illegal; or

(ii) if the Second Closing shall not have occurred on or before June 30, 2016.

(d) In the event of the termination of this Agreement as provided in Section 8.10(a) or Section 8.10(b), this Agreement shall forthwith become null and void.

SECTION 8.11 Recapitalization, Exchanges, Etc . 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) that may be issued in respect of, in exchange for or in substitution of, the Purchased Units and the Warrants, and shall be appropriately adjusted for combinations, unit splits, recapitalizations and the like of the Class A Convertible Preferred Units or the Common Units occurring after the date of this Agreement.

SECTION 8.12 Specific Performance . Damages in the event of breach of this Agreement by a Party hereto 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 hereto 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. The existence of this right will not preclude any such Party from pursuing any other rights and remedies at law or in equity that such Party may have.

Article II

REGISTRATION RIGHTS

Section 2.01 Shelf Registration .

(a) Shelf Registration . Within 180 calendar days of the Closing Date, the Partnership shall use its reasonable best efforts to prepare and file a Shelf Registration Statement with the SEC to permit the public resale of all Registrable Securities on the terms and conditions specified in this Section 2.01 (a “ Registration

Statement ”). The Registration Statement filed with the SEC pursuant to this Section 2.01(a) shall be on Form S-3 or, if Form S-3 is not then available to the Partnership, on Form S-1 or such other form of registration statement as is then available to effect a registration for resale of the Registrable Securities, covering the Registrable Securities, and shall contain a prospectus in such form as to permit any Selling Holder covered by such Registration Statement to sell such Registrable Securities pursuant to Rule 415 under the Securities Act (or any successor or similar provision adopted by the SEC then in effect) at any time beginning on the Effective Date for such Registration Statement. The Partnership shall use its reasonable best efforts to cause a Registration Statement filed pursuant to this Section 2.01(a) to be declared effective no later than 360 calendar days after the Closing Date (the “ Effectiveness Deadline ”). A Registration Statement shall provide for the resale pursuant to any method or combination of methods legally available to, and requested by, the Selling Holders, including by way of an Underwritten Offering, if such an election has been made pursuant to Section 2.04 of this Agreement. During the Effectiveness Period, the Partnership shall use its reasonable best efforts to cause a Registration Statement filed pursuant to this Section 2.01(a) to remain effective, and to be supplemented and amended to the extent necessary to ensure that such Registration Statement is available or, if not available, that another registration statement is available for the resale of the Registrable Securities until all Registrable Securities have ceased to be Registrable Securities. The Partnership shall prepare and file a supplemental listing application with the NYSE (or such other national securities exchange on which the Registrable Securities are then listed and traded) to list the Registrable Securities covered by a Registration Statement and shall use its reasonable best efforts to have such Registrable Securities approved for listing on the NYSE (or such other national securities exchange on which the Registrable Securities are then listed and traded) by the Effective Date of such Registration Statement, subject only to official notice of issuance. As soon as practicable following the Effective Date of a Registration Statement, but in any event within three Business Days of such date, the Partnership shall notify the Selling Holders of the effectiveness of such Registration Statement.

When effective, a Registration Statement (including the documents incorporated therein by reference) will comply as to form in all material respects with all applicable requirements of the Securities Act and the Exchange Act and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any prospectus contained in such Registration Statement, in the light of the circumstances under which a statement is made). If the Managing Underwriter of any proposed Underwritten Offering of Registrable Securities advises the Partnership that the inclusion of all of the Selling Holders’ Registrable Securities that the Selling Holders intend to include in such offering exceeds the number that can be sold in such offering without being likely to have an adverse effect on the price, timing or distribution of the Registrable Securities offered or the market for the Registrable Securities, then the Registrable Securities to be included in such Underwritten Offering shall include the number of Registrable Securities that such Managing Underwriter advises the Partnership can be sold without having such adverse effect, with such number to be allocated (i) first, to the Selling Holders, allocated among such Selling Holders pro rata on the basis of the number of Registrable Securities held by each such Selling Holder or in such other manner as such Selling Holders may agree, and (ii) second, to any other holder of securities of the Partnership having rights of registration that are neither expressly senior nor subordinated to the Holders in respect of the Registrable Securities.

(b) Failure to Go Effective . If a Registration Statement required to be filed by Section 2.01(a) is not declared effective on or prior to the Effectiveness Deadline, then each Holder shall be entitled to a payment (with respect to each Registrable Security held by the Holder), as liquidated damages and not as a penalty, of 0.25% of the Liquidated Damages Multiplier per 30-day period, which shall accrue daily, for the first 60 calendar days immediately following the Effectiveness Deadline, increasing by an additional 0.25% of the Liquidated Damages Multiplier per 30-calendar-day period, which shall accrue daily, for each subsequent 30-calendar-day period ( i.e. , 0.5% for 61-90 calendar days, 0.75% for 91-120 calendar days and 1.0%

thereafter), up to a maximum of 1.0% of the Liquidated Damages Multiplier per 30-calendar-day period, until such time as such Registration Statement is declared effective or when the Registrable Securities covered by such Registration Statement cease to be Registrable Securities (the “ Liquidated Damages ”). The Liquidated Damages payable pursuant to the immediately preceding sentence shall be payable within 10 Business Days after the end of each such 30-calendar-day period. Any Liquidated Damages shall be paid to each Holder in immediately available funds; provided, however , if the Partnership certifies that it is unable to pay Liquidated Damages in cash because such payment would result in a breach of any covenant or constitute a default under a credit facility, indenture, note purchase agreement or other debt instrument filed as an exhibit to the Partnership’s periodic reports filed with the SEC, then the Partnership may pay such Liquidated Damages using as much cash as permitted without breaching any such credit facility or other debt instrument and shall pay the balance of such Liquidated Damages (the “ In-Kind LD Amount ”) in kind in the form of the issuance of additional Common Units. Upon any issuance of Common Units as Liquidated Damages, the Partnership shall promptly (A) prepare and file an amendment to such Registration Statement prior to its effectiveness adding such Common Units to such Registration Statement as additional Registrable Securities and (B) prepare and file a supplemental listing application with the NYSE (or such other national securities exchange on which the Registrable Securities are then listed and traded) to list such additional Common Units. The determination of the number of Common Units to be issued as Liquidated Damages shall be equal to the In-Kind LD Amount divided by the VWAP Price calculated for the consecutive 10 trading day period ending on the close of trading on the trading day immediately preceding the date on which the Liquidated Damages payment is due, less a discount to such average closing price of 2.0%. The accrual of Liquidated Damages to a Holder shall cease (an “ LD Termination Date ,” and, each such period beginning on an Effectiveness Deadline and ending on an LD Termination Date being, an “ LD Period ”) at the earlier of (1) the Registration Statement being declared effective and (2) when the Holder’s Registrable Securities covered by such Registration Statement cease to be Registrable Securities. Any amount of Liquidated Damages shall be prorated for any period of less than 30 calendar days accruing during an LD Period. If the Partnership is unable to cause a Registration Statement to be declared effective on or prior to the Effectiveness Deadline as a result of an acquisition, merger, reorganization, disposition or other similar transaction, then the Partnership may request a waiver of the Liquidated Damages, and each Holder may individually grant or withhold its consent to such request in its discretion. For the avoidance of doubt, nothing in this Section 2.01(b) shall relieve the Partnership from its obligations under Section 2.01(a) .

Section 2.02 Piggyback Rights .

(a) Participation . So long as a Holder has Registrable Securities, if the Partnership proposes to file (i) a shelf registration statement other than a Registration Statement contemplated by Section 2.01(a) , (ii) a prospectus supplement to an effective shelf registration statement relating to the sale of equity securities of the Partnership, other than a Registration Statement contemplated by Section 2.01(a) and Holders may be included without the filing of a post-effective amendment thereto, or (iii) a registration statement, other than a shelf registration statement, in each case, for the sale of Common Units in an Underwritten Offering for its own account or that of another Person, or both, then promptly following the selection of the Managing Underwriter for such Underwritten Offering, the Partnership shall give notice of such Underwritten Offering to each Holder (together with its Affiliates) holding at least the Piggyback Threshold Amount of the then-outstanding Registrable Securities (calculated based on the Common Unit Price) and such notice shall offer such Holders the opportunity to include in such Underwritten Offering such number of Registrable Securities (the “ Included Registrable Securities ”) as each such Holder may request in writing; provided, however , that (A) the Partnership shall not be required to provide such opportunity to any such Holder that does not offer a minimum of the Piggyback Threshold Amount of Registrable Securities (based on the Common Unit Price), and (B) if the Partnership has been advised by the Managing Underwriter that the inclusion of Registrable Securities for sale for the benefit of the Holders will have an adverse effect on the price, timing or distribution

of the Common Units in the Underwritten Offering, then (x) if no Registrable Securities can be included in the Underwritten Offering in the opinion of the Managing Underwriter, the Partnership shall not be required to offer such opportunity to the Holders or (y) if any Registrable Securities can be included in the Underwritten Offering in the opinion of the Managing Underwriter, then the amount of Registrable Securities to be offered for the accounts of Holders shall be determined based on the provisions of Section 2.02(b) . Any notice required to be provided in this Section 2.02(a) to Holders shall be provided on a Business Day and receipt of such notice shall be confirmed by the Holder. Each such Holder shall then have two Business Days (or one Business Day in connection with any overnight or bought Underwritten Offering) after notice has been delivered to request in writing the inclusion of Registrable Securities in the Underwritten Offering. If no written request for inclusion from a Holder is received within the specified time, each such Holder shall have no further right to participate in such Underwritten Offering. If, at any time after giving written notice of its intention to undertake an Underwritten Offering and prior to the closing of such Underwritten Offering, the Partnership shall determine for any reason not to undertake or to delay such Underwritten Offering, the Partnership may, at its election, give written notice of such determination to the Selling Holders and, (1) in the case of a determination not to undertake such Underwritten Offering, shall be relieved of its obligation to sell any Included Registrable Securities in connection with such terminated Underwritten Offering, and (2) in the case of a determination to delay such Underwritten Offering, shall be permitted to delay offering any Included Registrable Securities as part of such Underwritten Offering for the same period as the delay in the Underwritten Offering. Any Selling Holder shall have the right to withdraw such Selling Holder’s request for inclusion of such Selling Holder’s Registrable Securities in such Underwritten Offering by giving written notice to the Partnership of such withdrawal at or prior to the time of pricing of such Underwritten Offering. Any Holder may deliver written notice (an “ Opt-Out Notice ”) to the Partnership requesting that such Holder not receive notice from the Partnership of any proposed Underwritten Offering; provided , however , that such Holder may later revoke any such Opt-Out Notice in writing. Following receipt of an Opt-Out Notice from a Holder (unless subsequently revoked), the Partnership shall not be required to deliver any notice to such Holder pursuant to this Section 2.02(a) and such Holder shall no longer be entitled to participate in Underwritten Offerings by the Partnership pursuant to this Section 2.02(a) . [The Holders indicated on Schedule A hereto as having opted out shall each be deemed to have delivered an Opt-Out Notice as of the date hereof.]

(b) Priority . Other than situations outlined in Section 2.01 of this Agreement, if the Managing Underwriter of any proposed Underwritten Offering of Common Units included in an Underwritten Offering involving Included Registrable Securities advises the Partnership that the total amount of Common Units that the Selling Holders and any other Persons intend to include in such offering exceeds the number of Common Units that can be sold in such offering without being likely to have an adverse effect on the price, timing or distribution of the Common Units offered or the market for the Common Units, then the Common Units to be included in such Underwritten Offering shall include the number of Registrable Securities that such Managing Underwriter advises the Partnership can be sold without having such adverse effect, with such number to be allocated (i) first, to the Partnership or other party or parties requesting or initiating such registration or to any other holder of securities of the Partnership having rights of registration pursuant to the Existing Registration Rights Agreement and (ii) second, by the Selling Holders who have requested participation in such Underwritten Offering and by the other holders of Common Units (other than holders of Registrable Securities) with registration rights entitling them to participate in such Underwritten Offering, allocated among such Selling Holders and other holders pro rata on the basis of the number of Registrable Securities or Common Units held by each applicable Selling Holder or other holder or in such manner as they may agree.

(c) Termination of Piggyback Registration Rights . Each Holder’s rights under this Section 2.02 shall terminate upon such Holder (together with its Affiliates) ceasing to hold at least the Piggyback Threshold Amount of Registrable Securities (calculated based on the Common Unit Price).

Section 2.03 Delay Rights .

Notwithstanding anything to the contrary contained herein, the Partnership may, upon written notice to (i) all Holders, delay the filing of a Registration Statement required under Section 2.01(a) , or (ii) any Selling Holder whose Registrable Securities are included in a Registration Statement or other registration statement contemplated by this Agreement, suspend such Selling Holder’s use of any prospectus that is a part of such Registration Statement or other registration statement (in which event the Selling Holder shall discontinue sales of the Registrable Securities pursuant to such Registration Statement or other registration statement contemplated by this Agreement but may settle any previously made sales of Registrable Securities) if the Partnership (x) is pursuing an acquisition, merger, reorganization, disposition or other similar transaction and the General Partner determines in good faith that the Partnership’s ability to pursue or consummate such a transaction would be materially adversely affected by any required disclosure of such transaction in such Registration Statement or other registration statement or (y) has experienced some other material non-public event the disclosure of which at such time, in the good faith judgment of the General Partner, would materially adversely affect the Partnership; provided, however , in no event shall (A) such filing of such Registration Statement be delayed under clauses (x) or (y) of this Section 2.03 for a period that exceeds 90 calendar days or (B) such Selling Holders be suspended under clauses (x) or (y) of this Section 2.03 from selling Registrable Securities pursuant to such Registration Statement or other registration statement for a period that exceeds an aggregate of 60 calendar days in any 180 calendar-day period or 105 calendar days in any 365 calendar-day period, in each case, exclusive of days covered by any lock-up agreement executed by a Selling Holder in connection with any Underwritten Offering. Upon disclosure of such information or the termination of the condition described above, the Partnership shall provide prompt notice, but in any event within one Business Day of such disclosure or termination, to the Selling Holders whose Registrable Securities are included in such Registration Statement and shall promptly terminate any suspension of sales it has put into effect and shall take such other reasonable actions to permit registered sales of Registrable Securities as contemplated in this Agreement.

If (i) the Selling Holders shall be prohibited from selling their Registrable Securities under a Registration Statement or other registration statement contemplated by this Agreement as a result of a suspension pursuant to the immediately preceding paragraph in excess of the periods permitted therein or (ii) a Registration Statement or other registration statement contemplated by this Agreement is filed and is declared effective but, during the Effectiveness Period, shall thereafter cease to be effective or fail to be usable for its intended purpose without being succeeded within 60 calendar days by a post-effective amendment thereto, a supplement to the prospectus or a report filed with the SEC pursuant to Section 13(a), 13(c), 14 or l5(d) of the Exchange Act, then, until the suspension is lifted or a post-effective amendment, supplement or report is filed with the SEC, but not including any day on which a suspension is lifted or such amendment, supplement or report is filed with the SEC, if applicable, each Selling Holder shall be entitled to a payment (with respect to each Registrable Security) from the Partnership, as liquidated damages and not as a penalty, of 0.25% of the Liquidated Damages Multiplier per 30-calendar-day period, which shall accrue daily, for the first 60 calendar days immediately following the earlier of (x) the date on which the suspension period exceeded the permitted period and (y) the 31st calendar day after such Shelf Registration Statement ceased to be effective or failed to be usable for its intended purposes, with such payment amount increasing by an additional 0.25% of the Liquidated Damages Multiplier per 30-day period, which shall accrue daily, for each subsequent 30-calendar-day period ( i.e. , 0.5% for 61-90 calendar days, 0.75% for 91-120 calendar days and 1.0% thereafter), up to a maximum of 1.00% of the Liquidated Damages Multiplier per 30-day

period (the “ Delay Liquidated Damages ”). For purposes of this paragraph, a suspension shall be deemed lifted with respect to a Selling Holder on the date that either (A) notice that the suspension has been terminated is delivered to such Selling Holder or (B) a post-effective amendment or supplement to the prospectus or report is filed with the SEC pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act. Any Delay Liquidated Damages shall cease to accrue pursuant to this paragraph upon the earlier of (1) a suspension being deemed lifted and (2) when such Selling Holder no longer holds Registrable Securities included in such Registration Statement, and shall be payable within 10 Business Days after the end of each such 30-day period. Any amount of Delay Liquidated Damages shall be prorated for any period of less than 30 calendar days in which the payment of Delay Liquidated Damages ceases. Any Delay Liquidated Damages shall be paid to each Selling Holder in immediately available funds.

Section 2.04 Underwritten Offerings . In the event that the Required Holders elect to include, other than pursuant to Section 2.02 of this Agreement, at least the lesser of (i) $15.0 million of Registrable Securities in the aggregate (calculated based on the Registrable Securities Amount) and (ii) 100% of the then outstanding Registrable Securities held by them under a Registration Statement pursuant to an Underwritten Offering, the Partnership shall, upon request by the Required Holders (such request, an “ Underwritten Offering Notice ” and such electing Required Holders, the “ Electing Holders ”), retain underwriters in order to permit the Electing Holders to effect such sale through an Underwritten Offering. provided, however , that the Required Holders shall have the option and right to require the Partnership to effect not more than three Underwritten Offerings pursuant to and subject to the conditions of this Section 2.04 , subject to a maximum of two Underwritten Offerings during any 12-month period. Upon delivery of such Underwritten Offering Notice to the Partnership, the Partnership shall as soon as practicable (but in no event later than one Business Day following the date of delivery of the Underwritten Offering Notice to the Partnership) deliver notice of such Underwritten Offering Notice to all other Holders, who shall then have two Business Days from the date that such notice is given to them to notify the Partnership in writing of the number of Registrable Securities held by such Holder that they want to be included in such Underwritten Offering. For the avoidance of doubt, any Holders notified about an Underwritten Offering by the Partnership after the Partnership has received the corresponding Underwritten Offering Notice may participate in such Underwritten Offering, but shall not count toward the $15.0 million of Registrable Securities required under clause (i) of this Section 2.04 to request an Underwritten Offering pursuant to an Underwritten Offering Notice. In connection with any Underwritten Offering under this Agreement, the Partnership shall be entitled to select the Managing Underwriter or Underwriters, but only with the consent of Holders of a majority of the Registrable Securities being sold in such Underwritten Offering, which shall not be unreasonably withheld, delayed or conditioned. In connection with an Underwritten Offering contemplated by this Agreement in which a Selling Holder participates, each Selling Holder and the Partnership shall be obligated to enter into an underwriting agreement that contains such representations, 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. Each Selling Holder may, at its option, require that any or all of the representations and warranties by, and the other agreements on the part of, the Partnership to and for the benefit of such underwriters also be made to and for such Selling Holder’s benefit and that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement also be conditions precedent to its obligations. No Selling Holder shall be required to make any representations or warranties to or agreements with the Partnership or the underwriters other than representations, warranties or agreements regarding such Selling Holder, its authority to enter into such underwriting agreement and to sell, and its ownership of, the securities whose offer and resale will be registered, on its behalf, its intended method of distribution and any other representation required by Law. If any Selling Holder disapproves of the terms of an underwriting, such Selling Holder

may elect to withdraw therefrom by notice to the Partnership, the Electing Holders and the Managing Underwriter; provided, however , that any such withdrawal must be made no later than the time of pricing of such Underwritten Offering. If all Selling Holders withdraw from an Underwritten Offering prior to the pricing of such Underwritten Offering, the events will not be considered an Underwritten Offering and will not decrease the number of available Underwritten Offerings the Required Holders have the right and option to request under this Section 2.04. No such withdrawal or abandonment shall affect the Partnership’s obligation to pay Registration Expenses pursuant to Section 2.08 ; provided, however , that if (A) certain Selling Holders withdraw from an Underwritten Offering after the public announcement at launch (the “ Launch ”) of such Underwritten Offering (such Selling Holders, the “ Post-Launch Withdrawing Selling Holders ”), and (B) all Selling Holders withdraw from such Underwritten Offering prior to pricing, other than in either clause (A) or (B) as a result of the occurrence of any event that would reasonably be expected to permit the Partnership to exercise its rights to suspend the use of a Registration Statement or other registration statement pursuant to Section 2.03, then the Post-Launch Withdrawing Selling Holders shall pay for all reasonable Registration Expenses incurred by the Partnership during the period from the Launch of such Underwritten Offering until the time all Selling Holders withdraw from such Underwritten Offering.

Section 2.05 Sale Procedures .

In connection with its obligations under this Article II , the Partnership shall, as expeditiously as possible:

(b) if a prospectus supplement will be used in connection with the marketing of an Underwritten Offering from a Registration Statement and the Managing Underwriter at any time shall notify the Partnership in writing that, in the sole judgment of such Managing Underwriter, inclusion of detailed information to be used in such prospectus supplement is of material importance to the success of the Underwritten Offering of such Registrable Securities, the Partnership shall use its reasonable best efforts to include such information in such prospectus supplement;

Following the provision of such notice, the Partnership agrees to as promptly as practicable amend or supplement the prospectus or prospectus supplement or take other appropriate action so that the prospectus or prospectus supplement does not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing and to take such other commercially 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 SEC or any other governmental agency or self-regulatory body or other body having jurisdiction (including any domestic or foreign securities exchange) relating to such offering of Registrable Securities;

(h) in the case of an Underwritten Offering, use its reasonable best efforts to furnish to the underwriters 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 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 reasonable best efforts to comply with all applicable rules and regulations of the SEC, and make available to its security holders, as soon as reasonably practicable, an earnings statement, covering a period of twelve months beginning within three months after the Effective Date of such Registration 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 and General Partner personnel as is reasonable and customary to enable such parties to establish a due diligence defense under the Securities Act; provided , that the Partnership need not disclose any non-public information to any such representative unless and until such representative has entered into a confidentiality agreement with the Partnership;

(k) use its reasonable best efforts to cause all such Registrable Securities registered pursuant to this Agreement to be listed on each securities exchange or nationally recognized quotation system on which the Common Units are then listed or quoted;

(m) provide a transfer agent and registrar for all Registrable Securities covered by such registration statement not later than the Effective Date of such registration statement;

(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 such Registrable Securities (including, making appropriate officers of the General Partner available to participate in any “road show” presentations before analysts, and other customary marketing activities (including one-on-one meetings with prospective purchasers of the Registrable Securities)), provided, however, that in the event the Partnership, using reasonable best efforts, is unable to make such appropriate officers of the General Partner available to participate in connection with any “road show” presentations and other customary marketing activities (whether in person or otherwise), the Partnership shall make such appropriate officers available to participate via conference call or other means of communication in connection with no more than one “road show” presentation per Underwritten Offering; and

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

The Partnership shall not name a Holder as an underwriter as defined in Section 2(a)(11) of the Securities Act in any Registration Statement without such Holder’s consent. If the staff of the SEC requires the Partnership to name any Holder as an underwriter as defined in Section 2(a)(11) of the Securities Act,

and such Holder does not consent thereto, then such Holder’s Registrable Securities shall not be included on such Registration Statement, such Holder shall no longer be entitled to receive Liquidated Damages under this Agreement with respect to such Holder’s Registrable Securities and the Partnership shall have no further obligations hereunder with respect to Registrable Securities held by such Holder, unless such Holder has not had an opportunity to conduct customary underwriter’s due diligence (including receipt of comfort letters and opinions of counsel) with respect to the Partnership at the time such Holder’s consent is sought.

Each Selling Holder, upon receipt of notice from the Partnership of the happening of any event of the kind described in Section 2.05(f) , shall forthwith discontinue offers and sales 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 Section 2.05(f) 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 shall, or shall request the Managing Underwriter, if any, to deliver to the Partnership (at the Partnership’s expense) all copies in their possession or control, other than permanent file copies then in such Selling Holder’s possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice.

Section 2.06 Cooperation by Holders .

The Partnership shall have no obligation to include Registrable Securities of a Holder in a Registration Statement or in an Underwritten Offering pursuant to Section 2.02(a) who has failed to timely furnish after receipt of a written request from the Partnership such information that the Partnership determines, after consultation with its counsel, is reasonably required in order for the registration statement or prospectus supplement, as applicable, to comply with the Securities Act, and any such Holder shall not be entitled to Liquidated Damages or Delay Liquidated Damages in connection with the applicable Registration Statement or other registration statement contemplated by this Agreement.

Section 2.07 Restrictions on Public Sale by Holders of Registrable Securities .

Each Holder of Registrable Securities that participates in an Underwritten Offering will enter into a customary letter agreement with underwriters providing such Holder will not effect any public sale or distribution of Registrable Securities during the 60 calendar-day period beginning on the date of a prospectus or prospectus supplement filed with the SEC with respect to the pricing of any 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 Affiliate of the Partnership or the General Partner on whom a restriction is imposed and (ii) the restrictions set forth in this Section 2.07 shall not apply to any Registrable Securities that are included in such Underwritten Offering by such Holder. In addition, this Section 2.07 shall not apply to any Holder that is not entitled to participate in such Underwritten Offering, whether because such Holder delivered an Opt-Out Notice prior to receiving notice of the Underwritten Offering or because such Holder (together with its Affiliates) holds less than the Piggyback Threshold Amount of the then-outstanding Registrable Securities (calculated based on the Registrable Securities Amount) or because the Registrable Securities held by such Holder may be disposed of without restriction pursuant to any section of Rule 144 under the Securities Act (or any successor or similar provision adopted by the SEC then in effect).

Section 2.08 Expenses .

(a) Expenses . Subject to the last sentence of Section 2.04 , the Partnership shall pay all reasonable Registration Expenses as determined in good faith by the General Partner, including, in the case of an

Underwritten Offering, the reasonable Registration Expenses of an Underwritten Offering, regardless of whether any sale is made pursuant to such Underwritten Offering. Each Selling Holder shall pay its pro rata share of all Selling Expenses in connection with any sale of its Registrable Securities hereunder. For the avoidance of doubt, each Selling Holder’s pro rata allocation of Selling Expenses shall be the percentage derived by dividing (i) the number of Registrable Securities sold by such Selling Holder in connection with such sale by (ii) the aggregate number of Registrable Securities sold by all Selling Holders in connection with such sale. In addition, except as otherwise provided in Sections 2.08 and 2.09 hereof, the Partnership shall not be responsible for legal fees incurred by Holders in connection with the exercise of such Holders’ rights hereunder.

(b) Certain Definitions . “ Registration Expenses ” means all expenses incident to the Partnership’s performance under or compliance with this Agreement to effect the registration of Registrable Securities on a Registration Statement pursuant to Section 2.01(a) or an Underwritten Offering covered under this Agreement, and the disposition of such Registrable Securities, including, without limitation, all registration, filing, securities exchange listing and NYSE fees, all registration, filing, qualification and other fees and expenses of complying with securities or blue sky laws, fees of the Financial Industry Regulatory Authority, Inc., fees of transfer agents and registrars, all word processing, duplicating and printing expenses, any transfer taxes, and the fees and disbursements of counsel and independent public accountants for the Partnership, including the expenses of any special audits or “cold comfort” letters required by or incident to such performance and compliance, and the reasonable fees and disbursements of one counsel for the Selling Holders participating in such Registration Statement or Underwritten Offering to effect the disposition of such Registrable Securities, selected by the Holders of a majority of the Registrable Securities initially being registered under such Registration Statement or other registration statement as contemplated by this Agreement, subject to the reasonable consent of the Partnership. “ Selling Expenses ” means all underwriting discounts and selling commissions or similar fees or arrangements allocable to the sale of the Registrable Securities, and fees and disbursements of counsel to the Selling Holders, except for the reasonable fees and disbursements of counsel for the Selling Holders required to be paid by the Partnership pursuant to Sections 2.08 and 2.09 .

Section 2.09 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 shall indemnify and hold harmless each Selling Holder thereunder, its directors, officers, managers, 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 (collectively, the “ Selling Holder Indemnified Persons ”), against any losses, claims, damages, expenses or liabilities (including reasonable attorneys’ fees and expenses) (collectively, “ Losses ”), joint or several, to which such Selling Holder Indemnified Person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such Losses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact (in the case of any prospectus, in light of the circumstances under which such statement is made) contained in (which, for the avoidance of doubt, includes documents incorporated by reference in) such Registration Statement or any other registration statement contemplated by this Agreement, any preliminary prospectus, prospectus supplement or final prospectus contained therein, or any amendment or supplement thereof, or any free writing prospectus relating thereto or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in light of the circumstances under which they were made) not misleading, and shall reimburse each such Selling Holder Indemnified Person for any legal or other expenses reasonably incurred by them in connection with investigating, defending or resolving any

such Loss or actions or proceedings; provided, however , that the Partnership shall not be liable in any such case if and to the extent that any such Loss arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by such Selling Holder Indemnified Person in writing specifically for use in such Registration Statement or such other registration statement, or prospectus supplement, as applicable. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Selling Holder Indemnified Person, and shall survive the transfer of such securities by such Selling Holder.

(b) By Each Selling Holder . Each Selling Holder agrees severally and not jointly to indemnify and hold harmless the Partnership, the General Partner, 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 such Registration Statement or any other registration statement contemplated by this Agreement, any preliminary prospectus, prospectus supplement or final prospectus contained therein, or any amendment or supplement thereof, or any free writing prospectus relating thereto; 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 2.09 . 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 2.09 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 indemnifying party shall settle any action brought against any indemnified party with respect to which such indemnified party is entitled to indemnification hereunder without the consent of the indemnified party, unless the settlement thereof imposes no liability or obligation on, and includes a complete and unconditional release from all liability of, the indemnified party.

(d) Contribution . If the indemnification provided for in this Section 2.09 is held by a court or government agency of competent jurisdiction to be unavailable to any indemnified party or is insufficient to hold them harmless in respect of any Losses, then each such indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result

of such Loss in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of such indemnified party on the other in connection with the statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations; provided, however , that in no event shall such Selling Holder be required to contribute an aggregate amount in excess of the 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, defending or resolving 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 such fraudulent misrepresentation.

(e) Other Indemnification . The provisions of this Section 2.09 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 2.10 Rule 144 Reporting .

With a view to making available the benefits of certain rules and regulations of the SEC that may permit the sale of the Registrable Securities to the public without registration, the Partnership agrees to use its reasonable best 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 (or any successor or similar provision adopted by the SEC then in effect), at all times from and after the date hereof;

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

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

Section 2.11 Transfer or Assignment of Registration Rights .

The rights to cause the Partnership to register Registrable Securities granted to the Purchasers by the Partnership under this Article II may be transferred or assigned by any Purchaser to one or more transferees or assignees of Registrable Securities, subject to the transfer restrictions provided in Section 4.11 of the Amended Partnership Agreement, provided, however, that (a) the Partnership is given written notice prior to any said transfer or assignment, stating the name and address of each of the transferee or assignee and

identifying the Registrable Securities with respect to which such registration rights are being transferred or assigned and (b) each such transferee or assignee assumes in writing responsibility for its portion of the obligations of such Purchaser under this Agreement.

Section 2.12 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 then outstanding Registrable Securities, enter into any agreement with any current or future holder of any equity securities of the Partnership that would allow such current or future holder to require the Partnership to include equity securities in any registration statement filed by the Partnership on a basis that is superior in any respect to the piggyback rights granted to the Holders pursuant to Section 2.02 .

NOW, THEREFORE , in consideration of the mutual covenants and agreements set forth herein and for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged by each of the Parties hereto, the Parties hereby agree as follows:

Agreement

Section 1. Board Observation Rights .

(a) Subsequent to the execution and delivery of this Agreement, during the period beginning on the Designation Rights Termination Date (as defined in Section 2(a) below) and ending on the Observation Rights Termination Date (defined in Section 1(c) below) (the “ Observation Period ”), the NGL Entities hereby grant Highstar the option and right, exercisable at any time during the Observation Period, upon written approval of a majority of the then-Outstanding Preferred Units and Warrants voting as a single class (with one vote per Preferred Unit and one vote per Warrant) held, directly or indirectly, by the Purchaser Group Members (“ Purchaser Approval ”), by delivery of a written notice signed by Highstar of such appointment to the NGL Entities (the “ Observer Notice ”), to appoint a single representative, who shall be employed by any of the Purchasers, their Affiliates and any fund, entity or account managed, advised or sub-advised directly or indirectly, by a Purchasers or any of its Affiliates, or the direct or indirect equity owners, including limited partners of a Purchaser or any of its Affiliates (collectively, the “ Purchaser Group Members ”) at the time of such appointment (the “ Board Observer ”), to attend all meetings (including telephonic) of the full Board during the Observation Period in an observer capacity. The Observer Notice shall be delivered to the NGL Entities prior to the Board Observer’s attendance of any meeting of the full Board.

(b) The Board Observer shall not constitute a member of the Board and shall not be entitled to vote on, or consent to, any matters presented to the Board. The NGL Entities shall (i) give the Board Observer written notice of the applicable meeting or action taken by written consent at the same time and in the same manner as notice is given to the members of the Board, (ii) provide the Board Observer with copies of all written materials and other information (including, without limitation, copies of minutes of meetings or written consents of the full Board) given to the members of the Board in connection with such meetings or actions taken by written consent at the same time such materials and information are furnished to such members of the Board, and (iii) provide the Board Observer with all rights to attend (whether in person or by telephone or other means of electronic communication as solely determined by the Board Observer) such meetings as a member of the Board. Notwithstanding any rights to be granted or provided to the Board Observer hereunder, the NGL Entities reserve the right to exclude the Board Observer from access to any material or meeting or portion thereof if the Board reasonably determines, in good faith, that such access would prevent the members of the Board from engaging in attorney-client privileged communication; provided , however , that such exclusion shall be limited to the portion of the material and/or meeting that is the basis for such exclusion and shall not extend to any portion of the material and/or meeting that does not involve or pertain to such exclusion. The Board Observer shall have no right to attend any meeting of any committee of the full Board (each, a “ Committee ”); provided , however , the NGL Entities shall (iv) give the Board Observer written notice of the applicable meeting or action taken by written consent of such Committee at the same time and in the same manner as notice is given to the members of such Committee and (v) with respect to the Audit Committee and the Compensation Committee of the Board, provide the Board Observer with copies of all written materials and other information (including, without limitation, copies of minutes of meetings or written consents of such Committee) given to the members of the Audit Committee and the Compensation Committee in connection with such meetings or actions taken by written consent at the same time such materials and information are furnished to such members of the Audit Committee and the Compensation Committee.

(c) The rights contained in this Section 1 shall immediately cease and terminate on the date (such date, the “ Observation Rights Termination Date ”) that the Purchaser Group Members no longer own, in the aggregate, at least 2.5% of the Partnership’s Outstanding Common Units (treating all Outstanding Preferred Units as having been converted at the Conversion Rate then in effect and all Warrants as having been exercised). From and after the Observation Rights Termination Date, the rights of Highstar in this Section 1 shall cease.

Section 2. Board Designation Rights .

(a) During the period (the “ Designation Period ”) beginning on the Initial Closing Date and ending on the date (the “ Designation Rights Termination Date ”) that the Purchaser Group Members no longer own, in the aggregate, either (i) at least 50% of the Preferred Units Outstanding on the last Closing Date or (ii) at least 5% of the Partnership’s Common Units Outstanding as of the date of determination (treating all Outstanding Preferred Units as having been converted at the Conversion Rate (as defined in Amendment No. 5) in effect as of the date of determination and all Warrants as having been exercised as of the date of determination), subject, in the case of clause (i) , to adjustment for unit split, reverse split and similar transactions applicable to the Preferred Units, Highstar shall, in accordance with the terms of this Agreement and the Voting Agreement, be entitled and have the right (the “ Board Designation Right ”) to designate one natural person for election to the Board (any such Director designated by Highstar, a “ Highstar Designated Director ”); provided , however , that such Highstar Designated Director shall, in the reasonable judgment of the General Partner, (i) have the requisite skill and experience to serve as a director of a public company, (ii) not be prohibited from serving as a director pursuant to any rule or regulation of the Securities and Exchange Commission (the “ Commission ”) or any national securities exchange on which the Partnership’s Common Units are then-listed or admitted to trading, and (iii) not be an employee or director of any Competitor (as defined in Amendment No. 5). If the General Partner determines in its reasonable judgment that a Highstar Designated Director does not meet one or more of the qualifications set forth in the immediately preceding sentence, the General Partner shall promptly deliver to Highstar a written statement (a “ Qualification Statement ”) describing the circumstances pursuant to which such Highstar Designated Director did not meet such qualifications.

(b) The Board Designation Right shall be exercisable at any time during the Designation Period, upon Purchaser Approval, by delivery to the General Partner of a written notice of such designation signed by Highstar (the “ Designation Notice ”). If a Qualification Statement in respect of a Highstar Designated Director is not delivered to Highstar by the General Partner within five (5) Business Days after the date of the applicable Designation Notice, then the General Partner shall promptly thereafter deliver a copy of the Designation Notice to each Voting Member, together with either a written notice of a meeting of the Members (as defined in the GP LLC Agreement), which meeting shall be called, in whole or in part, to vote on the election of the Highstar Designated Director, or a written consent of the Members in respect of the election of the Highstar Designated Director.

(c) During the Designation Period, the Highstar Designated Director may be removed or replaced by Highstar at any time, in accordance with the terms of the Voting Agreement, and by a majority of the remaining Directors for “cause” (as defined below); and any vacancy occurring by reason of the death, disability, resignation, removal or other cessation of a person serving as a Highstar Designated Director, shall be filled by Highstar in accordance Section 1.3 of the Voting Agreement. As used herein, “cause” means that the Highstar Designated Director (i) is prohibited from serving as a director under any rule or regulation of the Commission or any national securities exchange on which the Partnership’s Common Units are then-listed; (ii) while serving as the Highstar Designated Director, is convicted by a court of competent jurisdiction of a felony; (iii) a court of competent jurisdiction has entered, a final, non-appealable judgment finding the

Highstar Designated Director liable for actual fraud or willful misconduct against the Partnership (including, but not limited to, intentionally or willfully failing to observe the obligation of confidentiality contained in Section 5(a) of this Agreement); (iv) is determined to have acted intentionally or in bad faith in a manner that results in a material detriment to the assets, business or prospects of the Partnership ( provided , however , that no exercise of rights by a Purchaser Group Member pursuant to the Partnership Agreement or voting as a Highstar Designated Director solely in the interest of the Purchaser, or any effect on the Partnership as a result of the foregoing, shall be deemed to result in a material detriment to the assets, business or property of the Partnership) or (v) is terminated, removed or resigns for any reason from his or her position, if any, with any such Purchaser Group Member at which the Highstar Designated Director is then employed.

(d) Highstar agrees, upon the Partnership’s request, to timely provide the Partnership with accurate and complete information relating to the Highstar Designated Director as may be required to be disclosed by the Partnership under the Securities and Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder.

(e) The initial Highstar Designated Director shall be Christopher Beall.

Section 3. Additional Covenants

In addition, the General Partner will use reasonable best efforts to cause the approval prior to the Initial Closing or as promptly as possible thereafter, of an amendment to the GP LLC Agreement in the form attached hereto as Exhibit A (the “ GP LLC Agreement Amendment ”).

Section 4. Limitation of Liability; Indemnification; Business Opportunities .

(a) The Board Observer shall have (i) no fiduciary duty to the NGL Entities or to any Limited Partner (as defined in the Partnership Agreement) and (ii) no obligations to the NGL Entities under this Agreement, except as described in Section 5(a) of this Agreement, or to any Limited Partner.

(b) At all times while the Highstar Designated Director is serving as a member of the Board or the Board Observer is serving in such capacity in accordance with Section 1 of this Agreement, such Highstar Designated Director or Board Observer and the Purchaser Group Members may engage in, possess an interest in, or trade in the securities of, other business ventures of any nature or description, independently or with others, similar or dissimilar to the business of the NGL Entities, and the NGL Entities, the Board and their Affiliates shall have no rights by virtue of this Agreement in and to such independent ventures or the income or profits derived therefrom, and the pursuit of any such venture, even if competitive with the business of

the NGL Entities, shall not be deemed wrongful or improper. None of the Highstar Designated Director, the Board Observer or the Purchaser Group Members shall be obligated to present any investment opportunity to the NGL Entities even if such opportunity is of a character that the NGL Entities or any of their respective subsidiaries might reasonably be deemed to have pursued or had the ability or desire to pursue if granted the opportunity to do so, and each of the Highstar Designated Director, the Board Observer and the Purchaser Group Members shall have the right to take for such person’s own account (individually or as a partner or fiduciary) or to recommend to others any such investment opportunity. Notwithstanding the foregoing, the Highstar Designated Director and the Board Observer shall be subject to, and comply with, the requirement to maintain confidential information pursuant to this Agreement.

Section 5. Miscellaneous.

For the avoidance of doubt, the recipient of such Confidential Information from a Board Observer or Highstar Designated Director may further provide such information to (i) any other Purchaser Group Member and (ii) any legal counsel that has been engaged by such recipient to discuss such matters or information; provided , that any such recipient in clause (i) or (ii) agrees and acknowledges in writing that they are bound by the provisions of the Confidentiality Agreement. For purposes of this Agreement, “ Affiliates ” shall have the same meaning ascribed therefor in Amendment No. 5. For purposes of this Agreement, (i) the NGL Entities, on the one hand, and the Purchaser Group Members, on the other hand, shall not be considered Affiliates solely by virtue of such Purchaser Group Members holding Preferred Units or Warrants and (ii) any fund or account managed, advised or sub-advised, directly or indirectly, by any Purchaser or the direct or indirect equity owners, including any limited partners, of any Purchaser or its Affiliates, shall be considered an Affiliate of such Purchaser.

If any provision in this Agreement is held to be illegal, invalid, not binding or unenforceable, (i) such provision shall be fully severable and this Agreement shall be construed and enforced as if such illegal, invalid, not binding or unenforceable provision had never comprised a part of this Agreement, and the remaining provisions shall remain in full force and effect and (ii) the Parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible. When calculating the period of time before which, within which or following which any act is to be done or step taken pursuant to this Agreement, the date that is the reference date in calculating such period shall be excluded, and if the last day of such period is a non-Business Day, the period in question shall end on the next succeeding Business Day.

Any action against any Party relating to the foregoing shall be brought in any federal or state court of competent jurisdiction located within the State of Delaware, and the Parties hereto hereby irrevocably submit to the non-exclusive jurisdiction of any federal or state court located within the State of Delaware over any such action. Each of the Parties hereby irrevocably waives, to the fullest extent permitted by applicable Law, any objection that it may now or hereafter have to the laying of venue of any such dispute brought in such court or any defense of inconvenient forum for the maintenance of such dispute. Each of the Parties hereto agrees that a judgment in any such dispute may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law.

(f) Waiver of Jury Trial .

Pursuant to Section 5(a) of that certain Board Representation and Observation Rights Agreement (the “ Board Rights Agreement ”), dated as of May [•], 2016, by and among NGL Energy Holdings LLC, a Delaware limited liability company (the “ General Partner ”), NGL Energy Partners LP, a Delaware limited partnership (the “ Partnership ” and, together with the General Partner, the “ NGL Entities ”), the purchasers listed on the signature pages thereto (collectively, the “ Purchasers ”) and Highstar Capital IV, L.P., a Delaware limited partnership (“ Highstar ”), Highstar has exercised its right to appoint the undersigned as [an observer (the “ Board Observer ”)/its representative (the “ Highstar Designated Director ”)] to the board of directors of the General Partner (the “ Board ”), although the individual serving as the [Board Observer/Highstar Designated Director] may be changed from time to pursuant to the terms of the Board Rights Agreement and upon such other individual signing a confidentiality agreement in substantially the form hereof. The [Board Observer/Highstar Designated Director] acknowledges that at the meetings of the Board and at other times the [Board Observer/Highstar Designated Director] may be provided with and otherwise have access to non-public information concerning the NGL Entities and their Affiliates. Capitalized terms used but not otherwise defined herein, shall have the respective meanings ascribed therefor in the Board Rights Agreement. In consideration for and as a condition to the NGL Entities furnishing access to such information, the [Board Observer/Highstar Designated Director] hereby agrees to the terms and conditions set forth in this letter agreement (the “ Agreement ”):

1. As used in this Agreement, subject to Paragraph 3 below, “Confidential Information” means any and all non-public financial or other non-public information concerning the NGL Entities and their Affiliates that may hereafter be disclosed to the Board Observer by the NGL Entities, their Affiliates or by any of their directors, officers, employees, agents, consultants, advisors or other representatives (including financial advisors, accountants or legal counsel) (the “ Representatives ”) of the NGL Entities, including, without limitation, all notices, minutes, consents, materials, ideas or other information (to the extent constituting information concerning the NGL Entities and their Affiliates that is non-public financial or other non-public information) provided to the [Board Observer/Highstar Designated Director].

2. Except to the extent permitted by this Paragraph 2 or by Paragraph 3 or 4 , the [Board Observer/Highstar Designated Director] shall keep such Confidential Information strictly confidential; provided, that the [Board Observer/Highstar Designated Director] may, upon request from a Purchaser Group Member, share Confidential Information with such Purchaser Group Member so long as such individuals or entities agree to comply with, and be bound by, in all respects, the terms of this Agreement. For the avoidance of doubt, the recipient of such Confidential Information from the [Board Observer/Highstar Designated Director] may further provide such Confidential Information to (i) any other Purchaser Group Member and (ii) any legal counsel that has been engaged by such recipient to discuss such matters or Confidential Information; provided, that any such recipient in clause (i) or (ii) above agrees and acknowledges in writing to be bound by the terms of this Agreement.

3. The term “ Confidential Information ” does not include information that (i) is or becomes generally available to the public other than (a) as a result of a disclosure by the [Board Observer/Highstar Designated Director] in violation of this Agreement or (b) in violation of a confidentiality obligation to the NGL Entities known to the [Board Observer/Highstar Designated Director], (ii) is or becomes available to the [Board Observer/Highstar Designated Director] on a non-confidential basis from a source not known to have an obligation of confidentiality to the NGL Entities, (iii) was already known to the [Board Observer/Highstar Designated Director] at the time of disclosure, (iv) is disclosed to any Purchaser Group Member by the NGL Entities, their Affiliates or a Representative of the NGL Entities or (v) is independently developed by the [Board Observer/Highstar Designated Director] without reference to any Confidential Information disclosed to the [Board Observer/Highstar Designated Director].

4. In the event that the [Board Observer/Highstar Designated Director] is legally required or compelled to disclose the Confidential Information, the [Board Observer/Highstar Designated Director] shall use reasonable best efforts, to the extent permitted and practicable, to provide the NGL Entities with prompt prior written notice of such requirement so that the NGL Entities may seek, at such entities sole expense and cost, an appropriate protective order. If in the absence of a protective order, the [Board Observer/Highstar Designated Director] is nonetheless legally required or compelled to disclose Confidential Information, the [Board Observer/Highstar Designated Director] may disclose only the portion of the Confidential Information or other information that it is so legally required or compelled to disclose.

5. All Confidential Information disclosed by the NGL Entities or their Representatives to the [Board Observer/Highstar Designated Director] is and will remain the property of the NGL Entities, so long as such information remains Confidential Information.

6. It is understood and acknowledged that neither the NGL Entities nor any Representative makes any representation or warranty as to the accuracy or completeness of the Confidential Information or any component thereof.

7. It is further understood and agreed that money damages would not be a sufficient remedy for any breach of this Agreement by the [Board Observer/Highstar Designated Director] and that the NGL Entities shall be entitled to seek specific performance or any other appropriate form of equitable relief as a remedy for any such breach in addition to the remedies available to the NGL Entities at law.

8.

This Agreement is binding upon the parties hereto and their respective successors and assigns and inures to the benefit of the parties hereto and their respective successors and assigns.

9. If any provision of this Agreement is not enforceable in whole or in part, the remaining provisions of this Agreement will not be affected thereby. No failure or delay in exercising any right, power or privilege hereunder operates as a waiver thereof, nor does any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder.

10. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE, WITHOUT GIVING EFFECT TO ANY CHOICE OR CONFLICT OF LAW PROVISION (WHETHER OF THE STATE OF DELAWARE OR ANY OTHER JURISDICTION) THAT WOULD CAUSE THE APPLICATION OF THE LAWS OF ANY JURISDICTION OTHER THAN THE STATE OF DELAWARE.

11. This Agreement and all obligations herein will automatically expire one (1) year from the date the [Board Observer/Highstar Designated Director] ceases to act as [Board Observer/Highstar Designated Director].

12. This Agreement may be executed in one or more counterparts, each of which will be deemed to be an original copy of this Agreement, and all of which, when taken together, will constitute one and the same agreement. The exchange of copies of this Agreement and of signature pages by facsimile or electronic transmission constitutes effective execution and delivery of this Agreement as to the parties and may be used in lieu of the original Agreement.

5. Section 5.5(d)(i) is hereby amended and restated as follows:

(d) (i) Consistent with Treasury Regulation Sections 1.704-1(b)(2)(iv)(f) and 1.704-1(b)(2)(iv)(h)(2), on an issuance of additional Partnership Interests for cash or Contributed Property, the issuance of a Noncompensatory Option, the issuance of Partnership Interests as consideration for the provision of services, or the conversion of a Class A Preferred Unit in accordance with Section 5.12(b) , the Capital Accounts of all Partners and the Carrying Value of each Partnership property immediately prior to such issuance (or, in the case of a Conversion Date, immediately after such Conversion Date) shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property, as if such Unrealized Gain or Unrealized Loss had been recognized on an actual sale of each such property for an amount equal to its fair market value immediately prior to such issuance; provided, however , that in the event of the issuance of a Partnership Interest pursuant to the exercise of a Noncompensatory Option where the right to share in Partnership capital represented by such Partnership Interest differs from the consideration paid to acquire and exercise such option, the Carrying Value of each Partnership property immediately after the issuance of such Partnership Interest shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property and the Capital Accounts of the Partners shall be adjusted in a manner consistent with Treasury Regulation Section 1.704-1(b)(2)(iv)(s); provided, further , that in the event of an issuance of Partnership Interests for a de minimis amount of cash or Contributed Property, in the event of an issuance of a Noncompensatory Option to acquire a de minimis Partnership Interest, or in the event of an issuance of a de minimis amount of Partnership Interests as consideration for the provision of services, the General Partner may determine that such adjustments are unnecessary for the proper administration of the Partnership. Any such Unrealized Gain or Unrealized Loss (or items thereof) shall be allocated (A) if the operation of this sentence is triggered by the conversion of a Class A Preferred Unit, first among the Partners holding Common Units as may be necessary to cause the Capital Account attributable to each Common Unit to be the same, and (B) any remaining Unrealized Gain or Unrealized Loss shall be allocated among the Partners pursuant to Section 6.1 in the same manner as any item of gain or loss actually recognized would have been allocated. If the Unrealized Gain or Unrealized Loss allocated as a result of the occurrence of a Conversion Date is not sufficient to cause the Capital Account attributable to each Common Unit to be the same, then Capital Account balances shall be reallocated between the Partners holding such Units so as to cause the Capital Account attributable to each Common Unit to be the same, in accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(s)(3). In determining Unrealized Gain or Unrealized Loss in connection with the issuance of additional Partnership Interests or a Conversion Date, the aggregate cash amount and fair market value of all Partnership assets (including cash or cash equivalents) immediately prior to the issuance of additional Partnership Interests (or, in the case of an adjustment to the Carrying Value of Partnership property resulting from the exercise of a Noncompensatory Option (including conversion of a Class A Preferred Unit) immediately after the issuance of the Partnership Interest acquired pursuant to the exercise of the Noncompensatory Option) shall be determined by the General Partner using such method of valuation as it may adopt in its sole discretion. For this purpose, the General Partner may determine that it is appropriate to first determine an aggregate value for the Partnership, based on the current trading price of the Common Units, the fair market value of all other Partnership Interests at such time (on a fully converted basis) of all Partners at such time, and the amount of Partnership liabilities; and, if before the Conversion Date of any Class A Preferred Units or other Noncompensatory Options, may adjust the fair market value of all Partnership assets to reflect the difference, if any, between the fair market value of any Class A Preferred Units or other Noncompensatory Options for which the Conversion Date has not occurred and the aggregate Capital Accounts attributable to such Class A Preferred Units to the extent of any Unrealized Gain or Unrealized Loss that has not been reflected in the Partners’ Capital Accounts previously, consistent with the methodology of Treasury Regulation Section 1.704-1(b)(2)(iv)(h)(2). The General Partner shall allocate such aggregate value among the assets of the Partnership (in such manner as it determines) to arrive at a fair market value for individual properties.

6. Section 5.8 is hereby amended and restated as follows:

Section 5.12 Establishment of Class A Preferred Units

(a) General . The General Partner hereby designates and creates a series of Units to be designated as “Class A Preferred Units,” having the terms and conditions set forth herein.

(b) Distributions.

(i) Beginning with the Quarter ending June 30, 2016, the Class A Preferred Holders as of the applicable Record Date shall be entitled to receive distributions in accordance with the following provisions:

A) The Partnership shall pay a cumulative distribution equal to $0.3234 per Quarter in respect of each Outstanding Class A Preferred Unit, subject to adjustment in accordance with Section 5.12(b)(i)(B) and Section 5.12(d)(x) (the “ Class A Preferred Unit Distribution Amount ” and such distribution, a “ Class A Preferred Unit Distribution ” ). The Class A Preferred Unit Distribution Amount for the period ending June 30, 2016 shall be pro-rated for the periods commencing on the Initial Class A Closing Date, with respect to the Class A Preferred Units issued on such date, and the Second Class A Closing Date, with respect to the Class A Preferred Units issued on such date, and, in each case, ending on, and including, June 30, 2016.

B) Each Class A Preferred Unit Distribution shall be paid in cash at the Class A Preferred Unit Distribution Amount. If the Partnership fails to pay in full in cash any Class A Preferred Unit Distribution (or portion thereof) on the applicable Payment Date (a “ Payment Default ”), then (x) the amount of such accrued and unpaid Class A Preferred Unit Distributions will accumulate until paid in full in cash (or until the earlier conversion or

redemption of the Class A Preferred Units), (y) commencing as of the first day of the calendar Quarter in which the Payment Default occurs (the “ Default Effective Date ”), the Class A Preferred Unit Distribution Amount shall be (1) $0.3310 per Quarter for the period beginning on the Default Effective Date and ending on the 180th day immediately following the Default Effective Date and (2) $0.3385 per Quarter from and after the 181st day immediately following the Default Effective Date (such amount, as applicable, the “ Deficiency Rate ”), until such time as all accrued and unpaid Class A Preferred Unit Distributions, including any distributions accrued and unpaid at the Deficiency Rate and as increased pursuant to Section 5.12(b)(ii) , are paid in full in cash and (z) the Partnership shall not be permitted to, and shall not, declare or make (1) any distributions in respect of any Junior Securities, or (2) any distribution in respect of Parity Securities, other than the Class A Preferred Unit Distribution, unless and until all accrued and unpaid Class A Preferred Unit Distributions have been paid in full in cash; provided , however , that distributions may be declared and paid in respect of the Class A Preferred Units and any Parity Securities, as long as such distributions are declared and paid pro rata such that the amounts of distributions declared per Class A Preferred Unit and per unit of such Parity Security shall in all cases bear to each other the same ratio that accrued but unpaid and accumulated distributions per Class A Preferred Unit and per unit of such Parity Security bear to each other. Notwithstanding anything in this Section 5.12(b) to the contrary, at no time shall the Deficiency Rate exceed $$0.3385.

(ii) If a Payment Default has occurred, then the amount of any accrued but unpaid Class A Preferred Unit Distributions for which the Payment Date has passed but for which no payment has been made shall be increased at an annual rate of 10.75%, compounded Quarterly, until all accrued and unpaid Class A Preferred Unit Distributions have been paid in full in cash.

(iii) Subject to and without limiting the other provisions of this Section 5.12(b) , each Class A Preferred Unit shall have the right to share in any special distributions by the Partnership of cash, securities or other property and in the form of such cash, securities or other property Pro Rata with the Common Units, as if the Class A Preferred Units had converted into Common Units at the Conversion Rate then in effect, provided that special distributions shall not include regular Quarterly distributions paid in the normal course pursuant to Section 6.3(a) .

(iv) Class A Preferred Unit Distributions shall accrue on a daily basis; provided , however , that, with respect to any Class A Preferred Unit that is converted into Common Units in accordance with Section 5.12(d)(iii) , the holder thereof shall not be entitled to both a Class A Preferred Unit Distribution and a Common Unit distribution in respect of (A) the most recently completed Quarter or (B) the Quarter in which the conversion is consummated, but shall be entitled only to the distribution to be paid based upon the class of Units held as of the close of business on the Record Date in respect of each such Quarter.

(v) All Class A Preferred Unit Distributions shall be paid Quarterly, in arrears, on the earlier of: (A) the date that distributions are made on the Common Units for such Quarter pursuant to Section 6.3(a) or such earlier date after the end of such Quarter as the General Partner may determine, and (B) the date that is forty-five (45) days after the end of such Quarter (such date, the “ Payment Date ”).

(vi) For the avoidance of doubt and not withstanding anything in Sections 6.4 or 6.5 to the contrary, any Available Cash that is to be distributed pursuant to Section 6.4 or 6.5 shall be distributed first in accordance with this Section 5.12(b) ; provided , however , that for purposes of this Section 5.12(b) , Available Cash shall not include any deduction to provide funds for distributions under Section 6.4 or Section 6.5 in respect of any one or more of the next four Quarters.


(c)	Voting Rights.

(ii) The Class A Preferred Units will have such voting rights pursuant to this Agreement as such Class A Preferred Units would have if they were converted into Common Units, at the Conversion Rate then in effect, and shall vote together with the Common Units as a single class, except that the Class A Preferred Units shall be entitled to vote as a separate class on any matter on which Unitholders are entitled to vote that adversely affects the rights, powers, privileges or preferences of the Class A Preferred Units in relation to other classes of Partnership Interests or as required by law.

F) repurchase or redeem any class of Junior Securities (1) while a Payment Default is continuing or (2) prior to the third anniversary of the Initial Class A Closing Date, in an aggregate amount in excess of $100.0 million; provided , however , that the approval of a Class A Preferred Unit Majority shall not be required with respect to any such repurchase or redemption that would otherwise be permitted pursuant to Section 4.07(b)(6) of the Indentures;

I) incur any Indebtedness that would be included in the definition of Total Indebtedness (as defined in the Credit Agreement), if (1) a Payment Default is then continuing or (2) pro forma for such incurrence and the application of any proceeds thereof on or promptly following such incurrence, the Adjusted Leverage Ratio would exceed 5.50;

(d)	Conversion .

(i) One or more Class A Preferred Holders may elect, each in its own discretion, (A) at any time after the third anniversary of the Initial Class A Closing Date (the “ Initial Conversion Date ”), to convert all or any portion of the Class A Preferred Units held by such electing Class A Preferred Holder(s) in an aggregate amount equaling or exceeding the Minimum Conversion Amount into Common Units, (B) in the event of (1) receipt of a Voluntary Redemption Notice after the Initial Conversion Date or (2) any voluntary liquidation or winding-up of the Partnership, to convert all or any portion of the Class A Preferred Units held by such Class A Preferred Holder(s) into Common Units, or (C) upon a Change of Control, in accordance with an election made pursuant to Section 5.12(e)(iii) , to convert all, but not less than all, of the Class A Preferred Units held by such Class A Preferred Holder(s) into Common Units, in each case, by delivery of: (x) written notice to the Partnership, in the form set forth as Exhibit B hereto, setting forth the number of Class A Preferred Units it holds and the number of Class A Preferred Units it is electing to convert, and (y) if such Class A Preferred Units are Certificated, a Class A Preferred Unit Certificate to the Transfer Agent representing an amount of Class A Preferred Units at least equal to the amount such Class A Preferred Holder is electing to convert (or an instruction letter to the Transfer Agent if the Class A Preferred Units are in book-entry form), together with such additional information as may be requested by the Transfer Agent. The Partnership shall give each Class A Preferred Holder at least thirty (30) days prior written notice of any voluntary liquidation or winding-up of the Partnership or any Change of Control. Each Class A Preferred Unit converted into Common Units pursuant to this Section 5.12(d)(i) shall be converted into a number of Common Units equal to the Conversion Rate then in effect. In the case of any Certificate representing Class A Preferred Units which are converted in part only, upon such conversion the Transfer Agent shall authenticate and deliver to the Class A Preferred Holder thereof, at the expense of the Partnership, a new Certificate representing the number of Class A Preferred Units not so converted.

(ii) At any time after the eighth anniversary of the Initial Class A Closing Date, if all of the Forced Conversion Conditions are satisfied as of the Conversion Date (other than the Conversion Notice Conditions, which need only to be satisfied as of the date of the Conversion Notice), the General Partner, in its sole discretion, shall have the right (the “ Forced Conversion Right ”) to

convert all, but not less than all, of the Outstanding Class A Preferred Units into Common Units. To exercise the Forced Conversion Right, the Partnership shall deliver to each Class A Preferred Holder a written notice (the “ Conversion Notice ”) not more than five (5) and not less than three (3) Business Days prior to the expected Conversion Date. Immediately as of the close of business on the date of conversion pursuant to this Section 5.12(d)(ii) , which date shall not be (A) prior to the third Business Day following the date of the Conversion Notice and (B) with respect to any conversion of a Class A Preferred Unit that shall be settled in Common Units, prior the Record Date in respect of the most recently completed Quarter, each Outstanding Class A Preferred Unit shall automatically convert into a number of Common Units equal to the Conversion Rate then in effect.

(iii) Except as set forth below, the conversion of a Class A Preferred Unit pursuant to this Section 5.12(d) shall be settled, in the sole discretion of the General Partner, in cash or in Common Units, with settlements in cash being paid at the Cash Conversion Price; provided that in a conversion of multiple Class A Preferred Units, a portion of such Class A Preferred Units may, in the Company’s sole discretion, be settled in cash with the remainder being settled in Common Units; provided , further , that the ratio of Class A Preferred Units being settled in cash to Class A Preferred Units being settled in Common Stock shall be the same for all then-converting Class A Preferred Holders. The Partnership shall deliver written notice of the General Partner’s election as to method of settlement of a conversion of a Class A Preferred Unit to each then-converting Class A Preferred Holder at least three (3) Business Days prior to the expected Conversion Date. Notwithstanding the foregoing, the Partnership shall make a cash payment with respect to each Class A Preferred Unit converted pursuant to this Section 5.12(d) , in an amount equal to all accrued but unpaid and accumulated distributions, including any distributions accrued and unpaid at the Deficiency Rate, on such Class A Preferred Unit to, but not including, the Conversion Date; provided , however , that, with respect to any Class A Preferred Unit, the conversion of which shall be settled in Common Units, such accrued but unpaid and accumulated distributions shall not include any Class A Preferred Unit Distribution accrued in respect of (A) the most recently completed Quarter, if the Record Date in respect of such Quarter has not yet passed, or (B) the Quarter in which the conversion is consummated.

(iv) In lieu of issuing any fractional Common Unit upon the conversion of a Class A Preferred Unit pursuant to this Section 5.12(d) , the Partnership shall, in the sole discretion of the General Partner, round the number of Common Units issued upon conversion of each Class A Preferred Unit (A) up to the nearest whole Common Unit or (B) down to the nearest whole Common Unit and pay cash in lieu of any such fractional Common Unit.

(v) Upon conversion, the rights of a holder of converted Class A Preferred Units as a Class A Preferred Holder shall cease with respect to such converted Class A Preferred Units, including any rights under this Agreement with respect to Class A Preferred Holders, and such Person shall continue to

be a Limited Partner and have the rights of a holder of Common Units under this Agreement and the rights of a Class A Preferred Holder in respect of any Class A Preferred Units not converted. Each Class A Preferred Unit shall, upon its Conversion Date, be deemed to be transferred to, and cancelled by, the Partnership in exchange for the issuance of the Common Unit(s) into which such Class A Preferred Unit converted. Notwithstanding the foregoing, as the result of a conversion, a holder shall not lose or relinquish any claims or rights of action such holder may then or thereafter have as a result of such holder’s ownership of the converted Class A Preferred Units.

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

(vii) The Partnership shall keep free from preemptive rights a sufficient number of Common Units to permit the conversion of all outstanding Class A Preferred Units into Common Units to the extent provided in, and in accordance with, this Section 5.12(d) .

(viii) All Common Units delivered upon conversion of the Class A Preferred Units in accordance with this Section 5.12(d) shall be (1) newly issued and (2) duly authorized, validly issued, fully paid and non-assessable Limited Partner Interests in the Partnership, except as such non-assessability may be affected by Section 17-303, 17-607 or 17-804 of the Delaware Act, and shall be free from preemptive rights and free of any lien, claim, rights or encumbrances, other than those arising under the Delaware Act or this Agreement and other than restrictions on transfer under applicable securities laws.

(ix) The Partnership shall comply with all applicable securities laws pertaining to the issuance of any Common Units upon conversion of Class A Preferred Units and, if the Common Units are then listed, quoted or admitted to trading on the New York Stock Exchange or any other National Securities Exchange or other market, shall list or cause to have quoted or admitted to trading and keep listed, quoted or admitted to trading the Common Units issuable upon conversion of the Class A Preferred Units to the extent permitted or required by the rules of such exchange or market.

(x) If, after the Initial Class A Closing Date, the Partnership (A) makes a distribution on its Common Units in Common Units, (B) subdivides or splits its outstanding Common Units into a greater number of Common

Units, (C) combines or reclassifies its Common Units into a smaller number of Common Units or (D) issues by reclassification of its Common Units any Partnership Interests (including any reclassification in connection with a merger, consolidation or business combination in which the Partnership is the surviving Person), then the Conversion Price in effect at the time of the Record Date for such distribution or of the effective date of such subdivision, split, combination, or reclassification shall be proportionately adjusted so that the conversion of the Class A Preferred Units after such time shall entitle the holder to receive the aggregate number of Common Units (or shares of any Partnership Interests into which such shares of Common Units would have been combined, consolidated, merged or reclassified pursuant to clauses (C) and (D) above) that such holder would have been entitled to receive if the Class A Preferred Units had been converted into Common Units immediately prior to such Record Date or effective date, as the case may be, and in the case of a merger, consolidation or business combination in which the Partnership is the surviving Person, the Partnership shall provide effective provisions to ensure that the provisions of this Section 5.12 relating to the Class A Preferred Units shall not be abridged or amended and that the Class A Preferred Units shall thereafter retain the same powers, preferences and relative participating, optional and other special rights, and the qualifications, limitations and restrictions thereon, that the Class A Preferred Units had immediately prior to such transaction or event. An adjustment made pursuant to this Section 5.12(d)(x) shall become effective immediately after the Record Date in the case of a distribution and shall become effective immediately after the effective date in the case of a subdivision, combination, reclassification (including any reclassification in connection with a merger, consolidation or business combination in which the Partnership is the surviving Person) or split. Such adjustment shall be made successively whenever any event described above shall occur.

(e) Change of Control . In the event of a Change of Control, each Class A Preferred Holder shall have the option, at its sole election, to:

(i) require the Partnership to redeem in cash the Class A Preferred Units held by such Class A Preferred Holder at a price per Class A Preferred Unit equal to the COC Redemption Premium, plus any accrued but unpaid and accumulated distributions, including any distributions accrued and unpaid at the Deficiency Rate, on such Class A Preferred Units to, but not including, the Redemption Date;

(ii) if the Partnership is the surviving entity following such Change of Control, continue to hold Class A Preferred Units; or

(iii) convert all, but not less than all, of the Class A Preferred Units held by such Class A Preferred Holder into Common Units, at the Conversion Rate then in effect, in accordance with applicable provisions of Section 5.12(d) .

(f) Redemption.

(i) At any time after the first anniversary of the Initial Class A Closing Date, and subject to the right of a Class A Preferred Holder to elect conversion after the Initial Conversion Date pursuant to Section 5.12(d)(i)(B)(1) , the Partnership may redeem in cash all, but not less than all, of the Outstanding Class A Preferred Units at a price per Class A Preferred Unit equal to the then-applicable Redemption Premium, plus any accrued but unpaid and accumulated distributions, including any distributions accrued and unpaid at the Deficiency Rate, on such Class A Preferred Units to, but not including, the Redemption Date (the “ Voluntary Redemption Right ”), by providing written notice (the “ Voluntary Redemption Notice ”) to the Class A Preferred Holders not more than 45 and not less than 10 days (if the expected Redemption Date is on or prior to the Initial Conversion Date) or 20 days (if the expected Redemption Date is after the Initial Conversion Date) in advance of the expected Redemption Date set forth therein. Upon delivery of a Voluntary Redemption Notice, the Partnership shall be irrevocably obligated to redeem the Class A Preferred Units on the expected Redemption Date set forth in such notice.

(ii) Prior to the redemption or repurchase of one or more classes of Parity Securities (collectively, the “ Parity Redemption Securities ”), the Partnership shall, by written notice to the Class A Preferred Holders (the “ Notice of Parity Redemption ”), offer to redeem the Outstanding Class A Preferred Units in cash on a pro rata basis with such Parity Redemption Securities, at a price per Class A Preferred Unit equal to the applicable Redemption Premium, plus any accrued but unpaid and accumulated distributions, including any distributions accrued and unpaid at the Deficiency Rate, on such Class A Preferred Units to, but not including, the Redemption Date; provided , however , that if any Class A Preferred Holder fails to provide written notice of its intent to exercise its right to request redemption of its Class A Preferred Units within fifteen (15) Business Days of the Notice of Parity Redemption, such Class A Preferred Holder shall be deemed to have waived any and all rights to redemption pursuant to this Section 5.12(f)(ii) in such transaction. For purposes of this Section 5.12(f)(ii) , the pro rata allocation between the Class A Preferred Holders that elect to exercise their right to redemption pursuant to this Section 5.12(f)(ii) and the holders of such Parity Redemption Securities shall be based on the relative liquidation preferences of the securities held by the respective holders.

(iii) No Class A Preferred Holder shall have the right to cause the redemption of its Class A Preferred Units, in whole or in part, except as set forth in Sections 5.12(e)(i) and (f)(ii) . The Partnership shall not have right to cause the redemption Class A Preferred Units except as set forth in Section 5.12(f)(i) .

(g) Preemptive Rights.

Prior to the issuance of any Parity Securities or Senior Securities, the Partnership shall, by written notice to the Class A Preemptive Rights Holders (the “ Notice of Issuance ”), offer to sell such Parity Securities or Senior Securities to the

Class A Preemptive Rights Holders on terms and subject to conditions determined by the General Partner to be reasonable, which offer shall be made on a pro rata basis such that each Class A Preemptive Rights Holder shall be entitled to purchase a portion of such Parity Securities or Senior Securities equal to the quotient of (i) the number of Class A Preferred Units held by such Class A Preemptive Rights Holder on the date of the Notice of Issuance divided by (ii) the aggregate number of Class A Preferred Units held by all Class A Preemptive Rights Holders on the date of the Notice of Issuance (or as the Class A Preemptive Rights Holders may at such time otherwise agree among themselves); provided , that the offer of such Parity Securities or Senior Securities shall not be on a basis less favorable to the Class A Preemptive Rights Holders than is contemplated with respect to any purchaser thereof who is not a Class A Preemptive Rights Holder; provided , further , that (A) if any Class A Preemptive Rights Holder fails to provide written notice of its intent to exercise its right to purchase such Parity Securities or Senior Securities within fifteen (15) Business Days of the Notice of Issuance, such Class A Preemptive Rights Holder shall be deemed to have waived any and all rights to purchase such securities in such transaction and (B) if any Class A Preemptive Rights Holder waives or is deemed to have waived its right to purchase such Parity Securities or Senior Securities, the other Class A Preemptive Rights Holders shall be entitled to exercise such right as if such right was initially granted to such Class A Preemptive Rights Holders. Notwithstanding the foregoing, in no event shall the Partnership be obligated to offer to sell Parity Securities or Senior Securities to the Class A Preferred Holders pursuant to this Section 5.12(g) in connection with any (1) securities issued to the owners of another entity in connection with the acquisition of such entity by the Partnership by merger, consolidation, sale or exchange of securities, purchase of substantially all of the assets, or other reorganization whereby the Partnership acquires more than 50% of the voting power or assets of such entity; (2) Common Units or other Junior Securities (including options to purchase Common Units or other Junior Securities and Common Units or other Junior Securities issued upon exercise of such options) issued to employees, consultants or directors of the Partnership or the General Partner pursuant to plans, programs or agreements approved by the Board; (3) Senior Securities issued pursuant to any dividend, split, combination or other reclassification in respect of Senior Securities or pursuant to a recapitalization or reorganization of the Partnership in respect of Senior Securities; or (4) Parity Securities issued pursuant to any dividend, split, combination or other reclassification in respect of Parity Securities or pursuant to a recapitalization or reorganization of the Partnership in respect of Parity Securities provided in each case under this clause (4) the Class A Preferred Units are given ratable treatment.

(h) Certificates.

(i) If requested by a Class A Preferred Holder, the Class A Preferred Units shall be evidenced by certificates in such form as the Board of Directors may approve and, subject to the satisfaction of any applicable legal, regulatory and contractual requirements, may be assigned or transferred in a manner identical to the assignment and transfer of other Units; unless and until the Board of Directors determines to assign the responsibility to another Person, the General Partner will act as the Transfer Agent for the Class A Preferred Units. The certificates evidencing Class A Preferred Units shall be separately

identified and shall not bear the same CUSIP number as the certificates evidencing Common Units.

(ii) The certificate(s) representing the Class A Preferred Units may be imprinted with a legend in substantially the following form:

“THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS. THESE SECURITIES MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED IN THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO THE SECURITIES UNDER SUCH ACT OR PURSUANT TO AN EXEMPTION FROM REGISTRATION THEREUNDER AND, IN THE CASE OF A TRANSACTION EXEMPT FROM REGISTRATION, UNLESS SOLD PURSUANT TO RULE 144 UNDER SUCH ACT OR THE ISSUER HAS RECEIVED DOCUMENTATION REASONABLY SATISFACTORY TO IT THAT SUCH TRANSACTION DOES NOT REQUIRE REGISTRATION UNDER SUCH ACT. THIS SECURITY IS SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER SET FORTH IN (i) THE SECOND AMENDED AND RESTATED AGREEMENT OF LIMITED PARTNERSHIP OF THE PARTNERSHIP, DATED AS OF MAY 10, 2011, AS AMENDED OR RESTATED FROM TIME TO TIME, AND (ii) THE CLASS A PREFERRED UNIT PURCHASE AGREEMENT, DATED AS OF APRIL 21, 2016, BY AND BETWEEN THE PARTNERSHIP AND THE PURCHASERS PARTY THERETO, IN EACH CASE, A COPY OF WHICH MAY BE OBTAINED FROM THE PARTNERSHIP AT ITS PRINCIPAL EXECUTIVE OFFICES.”

(iii) In connection with a sale of Class A Preferred Units pursuant to an effective registration statement or in reliance on Rule 144 of the rules and regulations promulgated under the Securities Act, upon receipt by the Partnership of such information as the Partnership reasonably deems necessary to determine that the sale of the Class A Preferred Units is made in compliance with Rule 144, the Partnership shall remove or cause to be removed the restrictive legend from the certificate(s) representing such Class A Preferred Units (or the book-entry account maintained by the Transfer Agent), and the Partnership shall bear all costs associated therewith.

C) The balance , if any, 100% to the General Partner.

12. Section 6.1(d)(iii)(A) is hereby amended to add the following language at the end of the clause:

; provided , however, this Section 6.1(d)(iii)(A) shall not apply to any Excess Distribution in respect to or measured by a distribution to a Class A Preferred Unit and shall not apply to the extent distributions are not made with respect to a Deemed Warrant Unit with respect to any Record Date prior to the Vesting Date of such Deemed Warrant Unit.

13. Section 6.1(d)(xiii) shall be amended and restated to read as follows:

(xiii) Allocations with respect to Class A Preferred Units .

A) Items of Partnership gross income shall be allocated to the Class A Preferred Holders, Pro Rata, until the aggregate amount of gross income allocated to each Class A Preferred Holder pursuant hereto for the current and all previous taxable periods is equal to the cumulative Class A Preferred Unit Distribution Amount in respect of such Class A Preferred Holder’s Class A Preferred Units with respect to the current and all prior taxable periods; provided that gross income shall not be allocated pursuant to this Section 6.1(d)(xiii)(A) to the extent such allocation would cause the Per Unit Capital Account of a Class A Preferred Unit to exceed the Liquidation Preference; and provided, further, that the allocations to a Class A Preferred Holder under this Section 6.1(d)(xiii)(A) shall be reduced to the extent Class A Preferred Unit Distributions are properly treated as guaranteed payments under Section 707(c) of the Code or payments to such Class A Preferred Holder other than in its capacity as a partner pursuant to Section 707(a) of the Code.

B) Items of Partnership gross income shall be allocated to the Class A Preferred Holders, Pro Rata, until the aggregate amount of gross income allocated to each Class A Preferred Holder pursuant hereto for the current and all prior taxable periods is equal to the cumulative amount of all Net Losses allocated to such Class A Preferred Holder pursuant to Section 6.1(b)(ii) for all previous taxable periods; provided that gross income shall not be allocated pursuant to this Section 6.1(d)(xiii)(B) the extent such allocation would cause the Per Unit Capital Account of a Class A Preferred Unit to exceed the Liquidation Preference.

C) To the extent the Per Unit Capital Account of each Class A Preferred Unit is less than the Liquidation Preference, income and gain resulting from a Book-up Event shall be allocated to the holders of Class A Preferred Units, until the Per Unit Capital Account of each Class A Preferred Unit is equal to the Liquidation Preference.

D) Notwithstanding any other provision of this Section 6.1 (other than the Required Allocations), if (A) the Liquidation Date occurs prior to the conversion of the last Outstanding Class A Preferred Unit and (B) after having made all other allocations provided for in this Section 6.1 for the taxable period in which the Liquidation Date occurs, the Per Unit Capital Amount of each Class A Preferred Unit

does not equal or exceed the Liquidation Preference, then items of income, gain, loss and deduction for such taxable period shall be allocated among the Partners in a manner determined appropriate by the General Partner so as to cause, to the maximum extent possible, the Per Unit Capital Amount in respect of each Class A Preferred Unit to equal the Liquidation Preference. For the avoidance of doubt, the reallocation of items set forth in the immediately preceding sentence provides that, to the extent necessary to achieve the Per Unit Capital Amount balances described above, items of income and gain that would otherwise be included in Net Income or Net Loss, as the case may be, for the taxable period in which the Liquidation Date occurs, shall be reallocated from the Unitholders holding Units other than Class A Preferred Units to Unitholders holding Class A Preferred Units. In the event that (i) the Liquidation Date occurs on or before the date (not including any extension of time) prescribed by law for the filing of the Partnership’s federal income tax return for the taxable period immediately prior to the taxable period in which the Liquidation Date occurs and (ii) the reallocation of items for the taxable period in which the Liquidation Date occurs as set forth above in this Section 6.1(d)(xiii)(D) fails to achieve the Per Unit Capital Amounts described above, items of income, gain, loss and deduction that would otherwise be included in the Net Income or Net Loss, as the case may be, for such prior taxable period shall be reallocated among all Partners in a manner that will, to the maximum extent possible and after taking into account all other allocations made pursuant to this Section 6.1(d)(xiii)(D) , cause the Per Unit Capital Amount in respect of each Class A Preferred Unit to equal the Liquidation Preference.

14. Section 6.1(d) is hereby amended to add a new Section 6.1(d)(xv) :

(xv) Deemed Warrant Units . Following each Vesting Date, to the extent the Per Unit Capital Account attributable to any Deemed Warrant Unit for which a Vesting Date has occurred is less than the Per Unit Capital Account of a Common Unit:

A) Items of Partnership gross income, gain, loss and deduction resulting from a Book-Up Event or a Book-Down Event shall be allocated to the holders of Deemed Warrant Units and Common Units as necessary, to cause, to the extent possible, the Per Unit Capital Account attributable to any Deemed Warrant Units for which a Vesting Date has occurred to equal the Per Unit Capital Account of a Common Unit.

B) With respect to any taxable period in which the Vesting Date occurs (and if necessary subsequent tax periods), to the extent the Per Unit Capital Account of the Deemed Warrant Unit for which a Vesting Date occurs is not equivalent to the Per Unit Capital Amount of a Common Unit after application of Section 6.1(d)(xv)(A) , items of Partnership gross income, gain, deduction or loss for the taxable period shall be allocated 100% to each holder of Deemed Warrant Units for which a Vesting Date occurs in the proportion that the respective number of Deemed Warrant Units for which a Vesting Date occurs held by such holder bears to the total number of Deemed Warrant Units for which a Vesting Date occurs, until each such holder has been allocated an amount of gross income, gain, deduction or loss with respect to such Deemed Warrant Units for which a Vesting Date has occurred that causes the Capital Account attributable to each Deemed Warrant Unit, on a per Unit basis, to equal the Per Unit Capital Amount for a Common Unit on the Vesting Date. The purpose for this allocation is to establish uniformity between the Capital Accounts

underlying Deemed Warrant Units for which a Vesting Date occurs and the Capital Accounts underlying Common Units immediately prior to the Vesting Date.

C) If a holder of Deemed Warrant Units or Common Units granted upon exercise of the Deemed Warrant Units has a remaining Capital Account remaining after the disposing of all such Deemed Warrant Units or Common Units pursuant to Section 5.5(c)(iii) or in the event a Deemed Warrant Unit is not exercised, such holder shall be allocated items of loss and deduction equal to such remaining balance.

15. Section 6.2 is hereby amended to add a new Section 6.2(h) as follows:

(h) If, as a result of an exercise of a Noncompensatory Option, a Capital Account reallocation is required under Treasury Regulation Section 1.704-1(b)(2)(iv)(s)(3), the General Partner shall make corrective allocations pursuant to Treasury Regulation Section 1.704-1(b)(4)(x).

16. Article VI is hereby amended to add a new Section 6.14 as follows:

Section 6.14 Special Provisions Relating to the Class A Preferred Holders .

(a) Except as otherwise provided herein, a Class A Preferred Holder shall not have all of the rights and obligations of a Unitholder holding Common Units hereunder.

(b) Immediately upon the conversion of any Class A Preferred Unit into Common Units pursuant to Section 5.12(d) , the Unitholder holding a Class A Preferred Unit that is converted shall possess all of the rights and obligations of a Unitholder holding Common Units hereunder, including the right to vote as a Common Unitholder and the right to participate in allocations of income, gain, loss and deduction and distributions made with respect to Common Units; provided , however , that such converted Class A Preferred Units shall remain subject to the provisions of Section 6.14(c) .

(c) A Unitholder holding a Class A Preferred Unit that has converted into a Common Unit pursuant to Section 5.12(d) shall not be issued a Common Unit Certificate pursuant to Section 4.1 and shall not be permitted to transfer its converted Class A Preferred Units to a Person that is not an Affiliate of the holder until such time as the General Partner determines, based on advice of counsel, that upon transfer, each such converted Class A Preferred Unit should have intrinsic economic and U.S. federal income tax characteristics to the transferee, in all material respects, that are the same as the intrinsic economic and U.S. federal income tax characteristics that a Common Unit (other than a converted Class A Preferred Unit) would have to such transferee upon transfer, provided that in all events such determination shall be made within 5 Business Days of the date of conversion or receipt by the Partnership of the notice of transfer, as applicable. The General Partner shall act in good faith and shall make the determinations set forth in this Section 6.14(c) as soon as practicable following a Conversion Date or as earlier provided herein.

(d) Except as expressly set forth herein, all payments and distributions to holders of Class A Preferred Units shall be made ratably to them in accordance with the Class A Preferred Units held by them.

17. Article VI is hereby amended to add a new Section 6.15 as follows:

Section 6.15 Special Provisions Relating 2016 Warrants .

(a) For purposes of maintaining Capital Accounts and for purposes of Sections 6.1 and 6.2 , the 2016 Warrants shall be treated as exercised for Common Units that are not entitled to any distributions (each, a “ Deemed Warrant Unit ”).

(b) A Unitholder holding a Common Unit that has resulted from the exercise of a 2016 Warrant shall not be issued a Common Unit Certificate pursuant to Section 4.1 , if the Common Units are evidenced by Certificates, and shall not be permitted to transfer such Common Unit to a Person that is not an Affiliate of the holder until such time as the General Partner determines, based on advice of counsel, that each such Common Unit should have, as a substantive matter, like intrinsic economic and federal income tax characteristics, in all material respects, to the intrinsic economic and federal income tax characteristics of an Initial Common Unit. In connection with the condition imposed by this Section 6.15(b) , the General Partner may take whatever steps are required to provide economic uniformity to such Common Units in preparation for a transfer of such Common Units, including the application of Section 5.5(c)(ii) , Section 6.1(d)(xii) and Section 6.15(b) ; provided , however , that no such steps may be taken that would have a material adverse effect on the Unitholders holding Common Units.

A. Agreement in Effect . Except as hereby amended, the Partnership Agreement shall remain in full force and effect.

B. Applicable Law . This Amendment shall be construed in accordance with and governed by the laws of the State of Delaware, without regard to principles of conflicts of laws.

C. Severability .

D. Miscellaneous . Notwithstanding anything herein to the contrary, all measurements and references related to Unit prices, Unit numbers and distribution amounts (other than those expressed in percentages) herein, shall be, in each instance, appropriately adjusted for unit splits, combinations, distributions and the like.

E. Ratification of Partnership Agreement . Except as expressly modified and amended herein, all of the terms and conditions of the Partnership Agreement shall remain in full force and effect.

No Governmental Approval or Filing, which has not been obtained or made and is not in full force and effect, is required to authorize, or is required for, the execution and delivery of the Purchase Agreement, the Warrant, the Registration Rights Agreement and the Board Observation Rights Agreement by the General Partner on behalf of the Issuer, the execution and delivery of the Preferred Units Partnership Agreement Amendment and the Board Observation Rights Agreement by the General Partner or the consummation of the issuance and sale of the Securities pursuant to the Purchase Agreement. As used in this paragraph, “Governmental Approval or Filing” means any consent, approval, license, authorization or validation of, or filing, recording or registration with, any executive, legislative, judicial, administrative or regulatory body of the State of New York, the State of Delaware or the United States of America, pursuant to (i) applicable laws of the State of New York, (ii) applicable laws of the United States of America, (iii) the Delaware Limited Liability Company Act or (iv) the Delaware Revised Uniform Limited Partnership Act.

12. The offer, issue, sale and delivery of the Securities to the Purchasers, pursuant to and in the manner contemplated by the Purchase Agreement, the issuance of Common Units to holders of the Preferred Units upon conversion thereof, in accordance with the terms of such Preferred Units as set forth in the Partnership Agreement, and the issuance of Common Units to holder of the Warrant upon exercise thereof, in accordance with the terms thereof, do not require registration under the Securities Act; provided , however , that we express no opinion as to any subsequent resale or other transfer of any Security or any Common Unit issued upon conversion of a Preferred Unit or exercise of a Warrant.

13. The Issuer is not and, immediately after giving effect to the issuance and sale of the Securities occurring today and the application of proceeds therefrom as described in the Purchase Agreement, will not be, an “investment company” within the meaning of said term as used in the Investment Company Act of 1940, as amended.

We express no opinion as to the laws of any jurisdiction other than (i) applicable laws of the State of New York, (ii) applicable laws of the United States of America, (iii) certain other specified laws of the United States of America to the extent referred to specifically herein, (iv) the Delaware Limited Liability Company Act and (v) the Delaware Revised Uniform Limited Partnership Act. References herein to “applicable laws” mean those laws, rules and regulations that, in our experience, are normally applicable to transactions of the type contemplated by the Transaction Documents, without our having made any special investigation as to the applicability of any specific law, rule or regulation, and that are not the subject of a specific opinion herein referring expressly to a particular law or laws; provided, however, that such references (including, without limitation, those appearing in paragraphs 10 and 11 above) do not include any municipal or other local laws, rules or regulations, or any antifraud, environmental, labor, securities, tax, insurance or antitrust laws, rules or regulations.

Our opinions expressed herein are subject to the following additional assumptions and qualifications:

(i) The opinions set forth in paragraph 1 above as to the valid existence and good standing of the entities mentioned in such paragraph are based solely upon our review of certificates and other communications from the appropriate public officials.

(ii) In rendering the opinions set forth in paragraph 10 above regarding Applicable Agreements, we do not express any opinion, however, as to whether the execution or delivery of any of the Transaction Documents by any party, or the incurrence or performance by any party of its obligations thereunder, will constitute a violation of, or a default under or as a result of, any covenant, restriction or provision with respect to any financial ratio or test or any aspect of the financial condition or results of operations of the Issuer or the General Partner.

(iii) Our opinion in paragraphs 7, 8 and 9above may be:

(1) limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or transfer or other similar laws relating to or affecting the rights of creditors generally; and

(2) subject to the application of general principles of equity (regardless of whether considered in a proceeding in equity or at law), including, without limitation, the possible unavailability of specific performance, injunctive relief or any other equitable remedy and concepts of materiality, reasonableness, good faith and fair dealing.

(iv) Each of our opinions expressed in paragraphs 7, 8 and 9above insofar as it pertains to the choice of law provision of the instrument referred to in such paragraph, is rendered solely in reliance upon New York General Obligations Law Section 5-1401, and is expressly conditioned upon the assumption that the legality, validity, binding effect and enforceability of said provision will be determined by a court of the State of New York or a United States federal court sitting in New York and applying New York choice of law rules, including said Section 5-1401. We express no opinion as to such provision if such legality, validity, binding effect or enforceability is determined by any other court, and we call your attention to the decision of the United States District Court for the Southern District of New York in Lehman Brothers Commercial Corp. v. Minmetals Int’l Non-Ferrous Metals Trading Co ., 179 F. Supp. 2d 119 (S.D.N.Y. 2000), which, among other things, contains dicta relating to possible constitutional limitations upon said Section 5-1401. We express no opinion as to any such constitutional limitations upon said Section 5-1401 or their effect, if any, upon any opinion herein expressed.

(v) We express no opinion as to the validity, effect or enforceability of any provisions:

(1) purporting to establish particular notice periods or actions as “reasonable,” to modify rules of construction, to establish evidentiary standards or limitations periods for suits or proceedings to enforce such documents or otherwise, to establish certain determinations (including determinations of contracting parties and judgments of courts) as conclusive or conclusive absent manifest error, to commit the same to the discretion of any Person or permit any Person to act in its sole judgment or to waive rights to notice;

(2) providing that the assertion or employment of any right or remedy shall not prevent the concurrent assertion or employment of any other right or remedy, or that each and every remedy shall be cumulative and in addition to every other remedy or that any delay or omission to exercise any right or remedy shall not impair any other right or remedy or constitute a waiver thereof;

(3) relating to severability or separability;

(4) purporting to limit the liability of, or to exculpate, any Person, including, without limitation, any provision that purports to waive liability for violation of securities laws;

(5) purporting to waive damages;

(6) that constitute an agreement to agree in the future on any matter;

(7) that relate to indemnification, contribution or reimbursement obligations to the extent any such provisions (i) would purport to require any Person to provide indemnification, contribution or reimbursement in respect of the negligence, recklessness, willful misconduct or unlawful behavior of any Person, (ii) violate any law, rule or regulation (including any federal or state securities law, rule or regulation) or (iii) are determined to be contrary to public policy;

(8) purporting to establish any obligation of any party as absolute or unconditional regardless of the occurrence or non-occurrence or existence or non-existence of any event or other state of facts;

(9) purporting to obligate any party to conform to a standard that may not be objectively determinable or employing items that are vague or have no commonly accepted meaning in the context in which used;

(10) purporting to require the payment of liquidated damages for failure timely to comply with obligations under the Registration Rights Agreement;

(11) purporting to require that all amendments, waivers and terminations be in writing or the disregard of any course of dealing or usage of trade;

(12) purporting to provide for the submission to the jurisdiction of any court that lacks jurisdiction or relating to waiver of inconvenient forum; or

(13) purporting to require disregard of mandatory choice of law principles that could require application of a law other than the law expressly chosen to govern the instrument in which such provisions appear.

(vi) We express no opinion as to (1) Sections 3.06 or 3.13 of the Registration Rights Agreement, (2) Sections 15 or 26 of the Warrant or (3) the last sentence of Section 8.01, paragraph (a) of Section 8.03 or Section 8.12 of the Purchase Agreement.

(vii) In making our examination of executed documents, we have assumed (except to the extent that we expressly opine above) (1) the valid existence and good standing of each of the parties thereto, (2) that such parties had the power and authority, corporate, partnership, limited liability company or other, to enter into and to incur and perform all their obligations thereunder, (3) the due authorization by all requisite action, corporate, partnership, limited liability company or other, and the due execution and delivery by such parties of such documents and (4) to the extent such documents purport to constitute agreements, that each of such documents constitutes the legal, valid and binding obligation of each party thereto, enforceable against such party in accordance with its terms. In this paragraph (vii), all references to parties to documents shall be deemed to mean and include each of such parties, and each other person (if any) directly or indirectly acting on its behalf.

(viii) Except to the extent that we expressly opine above, we have assumed that the execution and delivery of the Transaction Documents, and the incurrence and performance of the obligations thereunder of the parties thereto, do not and will not contravene, breach, violate or constitute a default under (with the giving of notice, the passage of time or otherwise) (1) the certificate or articles of incorporation, certificate of formation, charter, bylaws, limited liability company agreement, limited partnership agreement or similar organic document of any such party, (2) any contract, indenture, mortgage, loan agreement, note, lease or other agreement or instrument, (3) any statute, law, rule, or regulation, (4) any judicial or administrative order or decree of any governmental authority, or (5) any consent, approval, license, authorization or validation of, or filing, recording or registration with, any governmental authority, in each case, to which any party to the Transaction Documents or any of its subsidiaries or any of their respective properties may be subject, or by which any of them may be bound or affected. Further, we have assumed the compliance by each such party, other than the Issuer and the General Partner, with all laws, rules and regulations applicable to it, as well as the compliance by each of the Issuer and the General Partner, and each other person (if any) directly or indirectly acting on its behalf, with all laws, rules and regulations that may be applicable to it by virtue of the particular nature of the business conducted by it or any goods or services produced or rendered by it or property owned, operated or leased by it, or any other facts pertaining specifically to it. In this paragraph (viii), all references to parties to the Transaction Documents, other than the first such reference, shall be deemed to mean and include each of such parties, and each other person (if any) directly or indirectly acting on its behalf.

(ix) Except to the extent that we expressly opine above, we have assumed that no authorization, consent or other approval of, notice to or registration, recording or filing with any court, governmental authority or regulatory body (other than routine informational filings, filings under the Securities Act and filings under the Securities Exchange Act of 1934, as amended) is required to authorize, or is required in connection with the transactions contemplated by the Transaction Documents, the execution or delivery thereof by or on behalf of any party thereto or the incurrence or performance by any of the parties thereto of its obligations thereunder.

(x) We point out that the submissions to the jurisdiction of a federal court and the waivers of objection to venue contained in the Transaction Documents cannot supersede a federal court’s discretion in determining whether to transfer an action to another court.

(xi) In rendering the opinion expressed in paragraph 12 above, we have taken into consideration not only the number of Purchasers, but also statements to us regarding their financial standing and investment experience, their past investment practices, the nature of the written information provided to them concerning the Issuer and statements to us regarding their respective business and proposed business and the ability and intention of the several Purchasers to honor their respective investment representations, and to the extent that the foregoing matters of fact are not within our personal knowledge, we have assumed:

(1) the accuracy of the representations and warranties of the Purchasers set forth in the Purchase Agreement;

(2) the due performance by the Issuer and the Purchasers of their respective covenants and agreements set forth in the Purchase Agreement;

(3) the accuracy of the statements and representations made to the Issuer by the Placement Agents in connection with the issuance and sale of the Securities to you;

(4) the accuracy of the statements and representations made to us by the Placement Agents in the Placement Agent Letters;

(5) that no form of general solicitation or general advertising was used by the Issuer or any other Person, in connection with the offer and sale of the Securities, including without limitation advertisements, articles, notices or other communications published in any newspaper, magazine or similar medium or broadcast over television or radio, or any seminar or meeting whose attendees have been invited by any general solicitation or general advertising;

(6) that neither the Issuer, nor anyone acting on its behalf, including, without limitation, the Placement Agents, has offered or sold or will offer or sell any securities or has solicited or will solicit any offer to acquire securities, if the sale of the Securities would be integrated with such offer or sale as a single offering for purposes of the Securities Act;

(7) that the Issuer or any of the Placement Agents had a preexisting relationship with each prospective purchaser of the Securities prior to its solicitation of any offer in connection with the issuance and sale of the Securities, and prior to any public announcement of the proposed issuance and sale of the Securities; and

(8) that immediately prior to soliciting any offer in connection with the Securities from any prospective purchaser, immediately prior to the sale of the Securities to any of the Purchasers, and after making reasonable inquiry, the Issuer or any of the Placement Agents had reasonable grounds to believe, and did believe, that each such prospective purchaser had such knowledge and experience in financial and business matters that it was capable of evaluating the merits and risks of its prospective investment in the Securities.

This opinion is being furnished only to you in connection with the sale of the Securities under the Purchase Agreement occurring today and is solely for your benefit and is not to be used, circulated, quoted or otherwise referred to for any other purpose or relied upon by any other Person, including any purchaser of any Security (or any Common Unit issuable upon exercise of any Warrant) from you and any subsequent purchaser of any Security (or any Common Unit issuable upon exercise of any Warrant), without our express written permission. Notwithstanding the foregoing, a copy of this opinion may be furnished solely for informational purposes to an assignee of the Securities and to your counsel, accountants, auditors and any regulatory agency or body with jurisdiction over you; provided that none of such persons, agencies or bodies may rely on this opinion, and we disclaim any responsibility to all such persons in respect of this opinion. The opinions expressed herein are as of the date hereof only and are based on laws, orders, contract terms and provisions, and facts as of such date, and we disclaim any obligation to update this opinion letter after such date or to advise you of changes of facts stated or assumed herein or any subsequent changes in law.

(e) Delivery of New Warrant . Unless the purchase rights represented by this Warrant shall have expired or shall have been fully exercised, the Partnership shall, at the time of delivery of the certificate or certificates representing the Warrant Units being issued in accordance with Section 3(c) hereof, deliver to the Holder a new Warrant evidencing the rights of the Holder to purchase the unexpired and unexercised Warrant Units called for by this Warrant. Such new Warrant shall in all other respects be identical to this Warrant.

(f) Valid Issuance of Warrant and Warrant Units; Payment of Taxes . With respect to the exercise of this warrant, the Partnership hereby represents, covenants and agrees:

(i) This Warrant is, and any Warrant issued in substitution for or replacement of this Warrant shall be, upon issuance, duly authorized and validly issued.

(ii) All Warrant Units issuable upon the exercise of this Warrant pursuant to the terms hereof shall be, upon issuance, and the Partnership shall take all such actions as may be necessary or appropriate in order that such Warrant Units are, validly issued, fully paid (to the extent required under applicable law and the Partnership Agreement) and non-assessable (except as such nonassessability may be affected by Sections 17-303, 17-607 and 17-804 of the Delaware LP Act), issued without violation of any preemptive or similar rights of any unitholder of the Partnership and free and clear of all taxes, liens and charges.

(iii) The Partnership shall take all such actions as may be necessary to ensure that all such Warrant Units are issued without violation by the Partnership of any applicable law or governmental regulation or any requirements of any domestic securities exchange upon which Common Units or other securities constituting Warrant Units may be listed at the time of such exercise (except for official notice of issuance which shall be immediately delivered by the Partnership upon each such issuance).

(iv) The Partnership shall use its reasonable best efforts to cause the Warrant Units, immediately upon such exercise, to be listed on any domestic securities exchange upon which Common Units or other securities constituting Warrant Units are listed at the time of such exercise.

(v) The Partnership shall pay all expenses in connection with, and all taxes and other governmental charges that may be imposed with respect to, the issuance or delivery of Warrant Units upon

exercise of this Warrant; provided, that the Partnership shall not be required to pay any tax or governmental charge that may be imposed with respect to any applicable withholding or the issuance or delivery of the Warrant Units to any Person other than the Holder, and no such issuance or delivery shall be made unless and until the Person requesting such issuance has paid to the Partnership the amount of any such tax, or has established to the satisfaction of the Partnership that such tax has been paid.

(g) Conditional Exercise . Notwithstanding any other provision hereof, if an exercise of any portion of this Warrant is to be made in connection with a sale of the Partnership (pursuant to a merger, sale of units, or otherwise), such exercise may at the election of the Holder be conditioned upon the consummation of such transaction, in which case such exercise shall not be deemed to be effective until immediately prior to the consummation of such transaction.

(h) Buy-In . In addition to any other rights available to the Holder, if the Partnership fails to deliver to the Holder a certificate or certificates representing the Warrant Units pursuant to an exercise within seven Business Days of such exercise, and if after such date the Holder is required by its broker to purchase (in an open market transaction or otherwise) Common Units to deliver in satisfaction of a sale by the Holder of the Warrant Units which the Holder anticipated receiving upon such exercise (a “ Buy-In ”), then the Partnership shall, at the Holder’s option, either (i) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including brokerage commissions, if any) for the Common Units so purchased (the “ Buy-In Price ”), at which point the Partnership’s obligation to deliver such certificate (and to issue such Common Units) shall terminate, or (ii) promptly honor its obligation to deliver to the Holder a certificate or certificates representing such Common Units and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of Common Units, times (B) the closing bid price on the date of exercise. The Holder shall provide the Partnership written notice indicating the amounts payable to the Holder in respect to the Buy-In, together with applicable confirmations and other evidence reasonably requested by the Partnership. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Partnership’s failure to timely deliver certificates representing Common Units upon exercise of this Warrant as required pursuant to the terms hereof.

4. Adjustment to Number of Warrant Units . In order to prevent dilution of the purchase rights granted under this Warrant, the number of Warrant Units issuable upon exercise of this Warrant shall be subject to adjustment from time to time as provided in this Section 4 (in each case, after taking into consideration any prior adjustments pursuant to this Section 4 ).

(a) Adjustment to Number of Warrant Units Upon Dividend, Subdivision or Combination of Common Units . If the Partnership shall, at any time or from time to time after the Original Issue Date, (i) pay a dividend or make any other distribution upon the Common Units or any other limited partner interests of the Partnership payable in Common Units or Convertible Securities, or (ii) subdivide (by any split, recapitalization or otherwise) its outstanding Common Units into a greater number of units, the number of Warrant Units issuable upon exercise of this Warrant immediately prior to any such dividend, distribution or subdivision shall be proportionately increased. If the Partnership at any time combines (by combination, reverse split or otherwise) its outstanding Common Units into a smaller number of units, the number of Warrant Units issuable upon exercise of this Warrant immediately prior to such combination shall be proportionately decreased. Any adjustment under this Section 4(a) shall become effective at the close of business on the date the dividend, subdivision or combination becomes effective.

(b) Adjustment to Number of Warrant Units Upon a Change of Control . In the event of any Change of Control, each Warrant shall, immediately after such Change of Control, remain outstanding and

shall thereafter, in lieu of or in addition to (as the case may be) the number of Warrant Units then exercisable under this Warrant, be exercisable for the kind and number of other securities or assets of the Partnership or of the successor Person resulting from such Change of Control to which the Holder would have been entitled upon such Change of Control if the Holder had exercised this Warrant in full immediately prior to the time of such Change of Control and acquired the applicable number of Warrant Units then issuable hereunder as a result of such exercise (without taking into account any limitations or restrictions on the exercisability of this Warrant); and, in such case, appropriate adjustment (in form and substance satisfactory to the Holder) shall be made with respect to the Holder's rights under this Warrant to insure that the provisions of this Section 4(b) shall thereafter be applicable, as nearly as possible, to this Warrant in relation to any securities or assets thereafter acquirable upon exercise of this Warrant. The provisions of this Section 4(b) shall similarly apply to successive Changes of Control. The Partnership shall not effect any such Change of Control unless, prior to the consummation thereof, the successor Person (if other than the Partnership) resulting from such Change of Control, shall assume, by written instrument substantially similar in form and substance to this Warrant and satisfactory to the Holder, the obligation to deliver to the Holder such securities or assets which, in accordance with the foregoing provisions, such Holder shall be entitled to receive upon exercise of this Warrant. Notwithstanding anything to the contrary contained herein, with respect to any Change of Control or other transaction contemplated by the provisions of this Section 4(b) , the Holder shall have the right to elect prior to the consummation of such event or transaction, to give effect to the exercise rights contained in Section 3 instead of giving effect to the provisions contained in this Section 4(b) with respect to this Warrant.

(c) Certain Events . If any event of the type contemplated by the provisions of this Section 4 but not expressly provided for by such provisions (including, without limitation, the granting of unit appreciation rights, phantom unit rights or other rights with equity features) occurs, then the Board shall make an appropriate adjustment in the number of Warrant Units issuable upon exercise of this Warrant so as to protect the rights of the Holder in a manner consistent with the provisions of this Section 4 ; provided, that no such adjustment pursuant to this Section 4(c) shall decrease the number of Warrant Units issuable as otherwise determined pursuant to this Section 4 .

(d) Certificate as to Adjustment .

(i) As promptly as reasonably practicable following any adjustment of the number of Warrant Units pursuant to the provisions of this Section 4 , but in any event not later than five Business Days thereafter, the Partnership shall furnish to the Holder a certificate of an executive officer setting forth in reasonable detail such adjustment and the facts upon which it is based and certifying the calculation thereof.

(ii) As promptly as reasonably practicable following the receipt by the Partnership of a written request by the Holder, but in any event not later than five Business Days thereafter, the Partnership shall furnish to the Holder a certificate of an executive officer certifying the number of Warrant Units or the amount, if any, of other, securities or assets then issuable upon exercise of the Warrant.

(e) Adjustment in Exercise Price . Upon any adjustment to the number of Warrant Units issuable upon exercise of this Warrant pursuant to this Section 4 (each, a “ Warrant Unit Adjustment ”), the Aggregate Exercise Price upon the exercise of this Warrant thereafter shall be adjusted by multiplying the Aggregate Exercise Price applicable prior to such Warrant Unit Adjustment by a fraction: the numerator of which shall be the number of Warrants Units issuable upon exercise of this Warrant immediately prior to such Warrant Unit Adjustment and the denominator of which shall be the number of Warrant Units issuable upon exercise of this Warrant immediately after such Warrant Unit Adjustment.

(f) Notices . In the event:

(i) that the Partnership shall take a record of the holders of its Common Units (or other securities at the time issuable upon exercise of the Warrant) for the purpose of entitling or enabling them to receive any dividend or other distribution, to vote at a meeting (or by written consent), to receive any right to subscribe for or purchase any class or any other securities, or to receive any other security; or

(ii) of the voluntary or involuntary dissolution, liquidation or winding-up of the Partnership; or

(iii) of any Change of Control;

then, and in each such case, the Partnership shall send or cause to be sent to the Holder at least 10 days prior to the applicable record date or the applicable expected effective date, as the case may be, for the event, a written notice specifying, as the case may be, (A) the record date for such dividend, distribution, meeting or consent or other right or action, and a description of such dividend, distribution or other right or action to be taken at such meeting or by written consent, or (B) the effective date on which such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding-up is proposed to take place, and the date, if any is to be fixed, as of which the books of the Partnership shall close or a record shall be taken with respect to which the holders of record of Common Units (or securities at the time issuable upon exercise of the Warrant) shall be entitled to exchange their Common Units (or such other securities) for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding-up, and the amount per unit and character of such exchange applicable to the Warrant and the Warrant Units.

5. Purchase Rights .In addition to any adjustments pursuant to Section 4 above, if at any time the Partnership grants, issues or sells any Common Units, Convertible Securities or rights to purchase units, warrants, securities or other property exclusively pro rata to the record holders of Common Units (the “ Purchase Rights ”), then the Holder shall be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder would have acquired if the Holder had held the number of Warrant Units acquirable upon complete exercise of this Warrant immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of Common Units are to be determined for the grant, issue or sale of such Purchase Rights.

6. Preemptive Rights.

(a) Prior to the issuance of any New Securities (as defined below in Section 6(b) ) by the Partnership, the Partnership shall offer to sell to each Holder its pro rata share of such New Securities by delivering written notice to such Holder (the “ Notice of Issuance ”), stating (i) the Company’s bona fide intention to offer such New Securities, (ii) the number of such New Securities to be offered and (iii) the price and general terms, if any, upon which the Partnership proposes to offer such New Securities; provided , that if any Holder fails to provide written notice of its intent to exercise its right to purchase its pro rata share of such New Securities within seven Business Days of the date of the Notice of Issuance, such Holder shall be deemed to have waived any and all rights to purchase such New Securities in such transaction. Each Holder’s pro rata share of any New Securities, for purposes of this Section 6 , shall be equal to the quotient of (x) the number of Common Units held by such Holder (including Warrant Units) on the date of the Notice of Issuance divided by (y) the number of Common Units outstanding (on a fully diluted basis assuming exercise of all outstanding options and warrants, including this Warrant) on the date of the Notice of Issuance.

(b) “ New Securities ” means any Common Units and rights, options or warrants to purchase Common Units, and securities of any type whatsoever that are, or may become, convertible into or exchangeable or exercisable for Common Units; provided, however , that New Securities shall not include (i) securities issued to the owners of another entity in connection with the acquisition of such entity by the Partnership by merger, consolidation, sale or exchange of securities, purchase of substantially all of the assets, or other reorganization whereby the Partnership acquires more than 50% of the voting power or assets of such entity; (ii) Common Units (including options to purchase Common Units and Common Units issued upon exercise of such options) issued to employees, consultants or directors of the Partnership or the General Partner pursuant to plans, programs or agreements approved by the Board; (iii) securities issued pursuant to any dividend, split, combination or other reclassification by the Partnership or the General Partner of the Common Units, or pursuant to a recapitalization or reorganization of the Partnership; (iv) securities (including without limitation the Warrant Units and Common Units issuable upon conversion of the Class A Convertible Preferred Units) issued upon the exercise of warrants or options, or upon the conversion of convertible securities, in each case regardless of whether such warrants, options or convertible securities are outstanding on the date hereof or issued hereafter; (v) Common Units issued in a transaction registered under the Securities Act pursuant to an at-the-market Common Units offering program of the Partnership; or (vi) Common Units issued in a firm commitment underwritten public offering registered under the Securities Act, but only if with respect to such public offering, (A) at least two Business Days prior to first publication of its intention to conduct such public offering of Common Units, the Partnership provides each Holder with a Notice of Issuance and (B) if not more than one Business Day after the date of the Notice of Issuance any Holder provides written notice of its intention to purchase (at the public offering price) Common Units in such offering, the Partnership instructs the managing underwriter, and shall use commercially reasonable efforts to cause the managing underwriter, to make available for purchase by such Holder, in such public offering and at the public offering price, a number of the Common Units equal to the lower of (1) such Holder’s pro rata share of all the Common Units being sold in such public offering and (2) the number of Common Units for which such Holder places an buy order with such managing underwriter. Notwithstanding any provision hereof to the contrary, each Notice of Issuance pertaining to a firm commitment underwritten public offering registered under the Securities Act need not include a particular price, and instead may state that the Partnership intends to sell Common Units to underwriters at customary discount to the public offering price that will be determined upon pricing of such offering. Each Holder’s pro rata share of the Common Units to be sold in a firm commitment underwritten public offering registered under the Securities Act shall be equal to the quotient of (x) the number of Common Units held by such Holder (including Warrant Units) on the date of the Notice of Issuance divided by (y) the number of Common Units outstanding (on a fully diluted basis assuming exercise of all outstanding options and warrants, including this Warrant) on the date of the Notice of Issuance.

(c) Any Holder may deliver written notice (an “ Opt-Out Notice ”) to the Partnership requesting that such Holder not receive any Notice of Issuance from the Partnership with respect to firm commitment underwritten public offerings of the Partnership’s Common Units; provided , however , that if a Holder has delivered an Opt-Out Notice, the Partnership shall not be required to comply with its obligations pursuant to Section 6(b)(vi)(A) and (B) with respect to such Holder; provided , further , that such Holder may later revoke any such Opt-Out Notice in writing. [ The Holders indicated on Schedule A hereto as having opted out shall each be deemed to have delivered an Opt-Out Notice as of the date hereof.]

7. Transfer of Warrant . Subject to the transfer conditions referred to in the legend endorsed hereon, this Warrant and all rights hereunder are transferable, in whole or in part, by the Holder without charge to the Holder, upon surrender of this Warrant to the Partnership at its then principal executive offices with a properly completed and duly executed Assignment in the form attached hereto as Exhibit B , together

with funds sufficient to pay any transfer taxes described in Section 3(f)(v) in connection with the making of such transfer. Upon such compliance, surrender and delivery and, if required, such payment, the Partnership shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees and in the denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant, if any, not so assigned and this Warrant shall promptly be cancelled. For the avoidance of doubt, Warrants may be transferred separately from Preferred Units.

8. Holder Not Deemed a Unitholder; Limitations on Liability . Except as described in the Board Observation Rights Agreement, the Partnership Agreement, the GP LLC Agreement, or otherwise specifically provided herein, prior to the issuance to the Holder of the Warrant Units to which the Holder is then entitled to receive upon the due exercise of this Warrant, the Holder shall not be entitled to vote or receive dividends or be deemed the holder of limited partner interests of the Partnership for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, as such, any of the rights of a unitholder of the Partnership or any right to vote, give or withhold consent to any corporate action (whether any reorganization, issue of limited partner interests, reclassification of limited partner interests, consolidation, merger, conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise. In addition, nothing contained in this Warrant shall be construed as imposing any liabilities on the Holder to purchase any securities (upon exercise of this Warrant or otherwise) or as a unitholder of the Partnership, whether such liabilities are asserted by the Partnership or by creditors of the Partnership. Notwithstanding this Section 8 , (i) the Partnership shall provide the Holder with copies of the same notices and other information given to the unitholders of the Partnership generally, contemporaneously with the giving thereof to the unitholders and (ii) the Partnership shall not amend or modify its Partnership Agreement in a manner adverse to any rights or benefits applicable to the Warrant Units thereunder.

9. Replacement on Loss; Division and Combination .

(a) Replacement of Warrant on Loss . Upon receipt of evidence reasonably satisfactory to the Partnership of the loss, theft, destruction or mutilation of this Warrant and upon delivery of an indemnity reasonably satisfactory to it (it being understood that a written indemnification agreement with an affidavit of loss of the Holder shall be a sufficient indemnity) and, in case of mutilation, upon surrender of such Warrant for cancellation to the Partnership, the Partnership at its own expense shall execute and deliver to the Holder, in lieu hereof, a new Warrant of like tenor and exercisable for an equivalent number of Warrant Units as the Warrant so lost, stolen, mutilated or destroyed; provided, that, in the case of mutilation, no indemnity shall be required if this Warrant in identifiable form is surrendered to the Partnership for cancellation.

(b) Division and Combination of Warrant . Subject to compliance with the applicable provisions of this Warrant as to any transfer or other assignment which may be involved in such division or combination, this Warrant may be divided or, following any such division of this Warrant, subsequently combined with other Warrants, upon the surrender of this Warrant or Warrants to the Partnership at its then principal executive offices, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the respective Holders or their agents or attorneys. Subject to compliance with the applicable provisions of this Warrant as to any transfer or assignment which may be involved in such division or combination, the Partnership shall at its own expense execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants so surrendered in accordance with such notice. Such new Warrant or Warrants shall be of like tenor to the surrendered Warrant or Warrants and shall be exercisable in the aggregate for an equivalent number of Warrant Units as the Warrant or Warrants so surrendered in accordance with such notice.

10. No Impairment . The Partnership shall not, by amendment of its Certificate of Formation or Partnership Agreement, or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed by it hereunder, but shall at all times in good faith assist in the carrying out of all the provisions of this Warrant and in the taking of all such action as may reasonably be requested by the Holder in order to protect the exercise rights of the Holder against dilution or other impairment, consistent with the tenor and purpose of this Warrant .

11. Agreement to Comply with the Securities Act; Legend . The Holder, by acceptance of this Warrant, agrees to comply in all respects with the provisions of this Section 11 and the restrictive legend requirements set forth on the face of this Warrant and further agrees that such Holder shall not offer, sell or otherwise dispose of this Warrant or any Warrant Units to be issued upon exercise hereof except under circumstances that will not result in a violation of the Securities Act. All Warrant Units issued upon exercise of this Warrant (unless registered under the Securities Act or the conditions for the removal of the legend set forth in Section 8.06 of the Partnership Agreement are otherwise satisfied) shall be stamped or imprinted with a legend in substantially the following form:

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

12. Warrant Register . The Partnership shall keep and properly maintain at its principal executive offices books for the registration of the Warrant and any transfers thereof. The Partnership may deem and treat the Person in whose name the Warrant is registered on such register as the Holder thereof for all purposes, and the Partnership shall not be affected by any notice to the contrary, except any assignment, division, combination or other transfer of the Warrant effected in accordance with the provisions of this Warrant.

13. Notices . All notices, requests, consents, claims, demands, waivers and other communications hereunder shall be in writing and shall be deemed to have been given: (a) when delivered by hand (with written confirmation of receipt); (b) when received by the addressee if sent by a nationally recognized overnight courier (receipt requested); (c) on the date sent by facsimile or e-mail of a PDF document (with confirmation of transmission) if sent during normal business hours of the recipient, and on the next Business Day if sent after normal business hours of the recipient; or (d) on the third day after the date mailed, by certified or registered mail, return receipt requested, postage prepaid. Such communications must be sent to the respective parties at the addresses indicated below (or at such other address for a party as shall be specified in a notice given in accordance with this Section 13 ).

Exhibit 99.1

NGL Energy Partners LP Announces Investment from funds managed by Oaktree Capital Management, L.P., Declares Quarterly Cash Distribution and Provides Partnership Update

NGL Energy Partners LP (NYSE: NGL) (the "Partnership" or “NGL”) today announced several strategic actions along with updated guidance. The Partnership:


•	Announces $200 million private placement of 10.75% Class A Convertible Preferred Units and formation of a strategic relationship with funds managed by Oaktree Capital Management L.P. (“Oaktree”);


•	Declares a temporary reduction in quarterly cash distribution to $0.39 per common unit ($1.56 per common unit annualized) which will generate an additional $170 million of coverage over the next year;


•	Updates guidance for Fiscal Year 2016 and initiates projections for Fiscal Year 2017, as well as an update on the Grand Mesa project;


•	Reports enhanced liquidity and balance sheet since December 2015 with the sales of Class A Convertible Preferred Units, interests in TransMontaigne GP LLC and common units of TransMontaigne Partners L.P. and senior note repurchases resulting in the ability to fund growth projects while also significantly reducing outstanding debt; and


•	Will host an analyst and investor call with Management scheduled for 11:00am EDT on Friday, April 22, 2016

Class A Convertible Preferred Units

The Partnership has entered into an agreement to issue $200 million of 10.75% Class A Convertible Preferred Units ("Preferred Units") to Oaktree. Oaktree will acquire 16.6 million Preferred Units at a price of $12.03 per unit as well as 3.6 million warrants, which are subject to certain vesting and exercise terms. NGL expects to use the net proceeds from the issuance of the Preferred Units to repay borrowings outstanding on its revolving credit facility, which may be re-borrowed in the future to fund capital expenditures and for other general partnership purposes. The Partnership and Oaktree have also formed a strategic relationship to pursue future opportunities within the Partnership’s current business segments.

“I believe this is a very positive transaction for NGL and I look forward to having Oaktree as a partner and represented on our Board. The investment by Oaktree is a strong endorsement of our business model, strategy and future growth projects. We plan to jointly pursue certain attractive assets together that Oaktree will assist in financing/structuring and NGL will operate,” stated Mike Krimbill, CEO of NGL. “Over the past several months, NGL has taken what I believe to be the necessary actions to position the Partnership for success, regardless of this low commodity price environment. In only five months since our joint ownership arrangement regarding the Saddlehorn pipeline, we have significantly enhanced liquidity, strengthened the balance sheet and aligned with a strategic investor which we expect will provide us with the capital to selectively pursue organic growth projects and strategic acquisitions at accretive multiples.”

“Oaktree is pleased to make an investment in NGL. The Partnership’s strong management team, diversified asset base, attractive growth prospects and improved balance sheet, make it an exciting investment opportunity. We look forward to partnering with the NGL team to continue to implement the Partnership’s strategy and capitalize on growth opportunities in the future,” said Managing Director and Co-Portfolio Manager of Oaktree’s Infrastructure Investing strategy Chris Beall.

Closing of the sale of the Preferred Units and warrants is scheduled to occur prior to the end of June 2016, and is subject to certain closing conditions.

Quarterly Distribution

The Board of Directors of the Partnership's general partner decided to reduce the distribution 39% and declared a quarterly cash distribution of $0.39 per common unit ($1.56 per common unit on an annualized basis) for the quarter ended March 31, 2016, which it anticipates will continue for three additional quarters under current market conditions. In light of continued illiquid and unattractive debt and equity capital market conditions, the Board made the difficult decision to reduce the distribution per common unit by $1.00 on an annualized basis, which will provide NGL with approximately $170 million of annual cash savings to enhance liquidity, repay indebtedness and/or invest in selected growth projects in the future. The general partner, through its incentive distribution rights, will forgo approximately $64 million of distributions over the four-quarter period, which is included in the $170 million of annual cash savings to the Partnership.

The distribution will be payable on May 13, 2016 to common unitholders of record at the close of business on May 3, 2016.

Partnership Update and Guidance

Since December 31, 2015, NGL has sold TransMontaigne GP LLC (“TLP GP”) for $350 million; sold its 3.17 million common units in TransMontaigne Partners L.P. (“TLP”) for approximately $112 million; expects to raise $200 million in this issuance of Preferred Units; and expects to have approximately $170 million of additional distribution coverage over the next year from the reduction in distributions. These transactions in aggregate provide over $830 million in cash to be deployed in the Partnership's business and used to strengthen the balance sheet. In addition, the sale of TLP GP results in a $247 million reduction in debt from the December 31, 2015 balance sheet due to NGL’s sale of TLP GP and the resulting deconsolidation of TLP. NGL has also repurchased and retired nearly $100 million of its outstanding high yield bonds since the beginning of February 2016 at then market prices. These events will have combined for more than a $1.0 billion reduction in debt since December 31, 2015, of which a portion has been re-borrowed to fund growth capital expenditures.

The Partnership’s Grand Mesa project is on schedule and NGL’s projected capital costs are under-budget by approximately $20 million. We anticipate crude oil shipments to begin by November 1, 2016. We have been in contact with our shippers and the Partnership currently expects year one EBITDA to be approximately $120 million, year two EBITDA to be approximately $150 million and the average contract term on the pipeline to increase to nine years.

Management guidance for the fourth quarter of Fiscal Year 2016 Adjusted EBITDA is now $150-$160 million, which results in Adjusted EBITDA of $420-$430 million for the entire 2016 Fiscal Year. The Partnership has invested approximately $140 million in growth capital expenditures during the quarter, of which approximately $110 million related to the Grand Mesa project. Guidance for Fiscal Year 2017 Adjusted EBITDA is $500 million, which includes Adjusted EBITDA from Grand Mesa for five months at approximately $10 million per month. Management currently expects growth capital expenditures for Fiscal Year 2017 to be between $200 million to $300 million, which does not include any expenditures associated with the proposed relationship with Oaktree. With these forecasts and the change in distribution policy, Fiscal Year 2017 common unit coverage is expected to increase to 2.0x. Management would expect distribution growth to resume in Fiscal Year 2018 and would target distribution coverage between 1.3 - 1.5x.

About Oaktree Capital

Oaktree Capital Group, LLC (NYSE: OAK) is a leader among global investment managers specializing in alternative investments, with $97 billion in assets under management as of December 31, 2015. The firm emphasizes an opportunistic, value-oriented and risk-controlled approach to investments in distressed debt, corporate debt (including high yield debt and senior loans), control investing, convertible securities, real estate and listed equities.

NGL defines EBITDA as net income (loss) attributable to parent equity, plus interest expense, income tax provision (benefit), and depreciation and amortization expense. NGL defines Adjusted EBITDA as EBITDA excluding net unrealized gains and losses on derivatives, lower of cost or market adjustments, gains and losses on disposal or impairment of assets, and equity-based compensation expense. NGL also includes in Adjusted EBITDA certain inventory valuation adjustments related to its refined products and renewables segment, as described below. EBITDA and Adjusted EBITDA should not be considered alternatives to net income, income before income taxes, cash flows from operating activities, or any other measure of financial performance calculated in accordance with accounting principles generally accepted in the United States (“GAAP”) as those items are used to measure operating performance, liquidity or the ability to service debt obligations. NGL believes that EBITDA provides additional information to investors for evaluating its ability to make quarterly distributions to its unitholders and is presented solely as a supplemental measure. NGL believes that Adjusted EBITDA provides additional information to investors for evaluating NGL’s financial performance without regard to financing methods, capital structure, and historical cost basis. Further, EBITDA and Adjusted EBITDA, as NGL defines them, may not be comparable to EBITDA and Adjusted EBITDA or similarly titled measures used by other entities.

Other than for its refined products and renewables segment, for purposes of its Adjusted EBITDA calculation, NGL makes a distinction between realized and unrealized gains and losses on derivatives. During the period when a derivative contract is open, NGL records changes in the fair value of the derivative as an unrealized gain or loss. When a derivative contract matures or is settled, NGL reverses the previously recorded unrealized gain or loss and records a realized gain or loss. NGL does not draw such a distinction between realized and unrealized gains and losses on derivatives of its refined products and renewables segment. The primary hedging strategy of NGL’s refined products and renewables segment is to hedge against the risk of declines in the value of inventory over the course of the contract cycle, and many of the hedges are six months to one year in duration at inception. NGL adds this to Adjusted EBITDA because the gains and losses associated with derivative contracts of this segment, which are intended primarily to hedge inventory holding risk, also impact Adjusted EBITDA.
