NOW THEREFORE, the General Partner does hereby amend the Partnership Agreement as follows:

A. Amendment. The Partnership Agreement is hereby amended as follows:

a. Section 5.14(b)(ii)(A) is hereby amended and restated in its entirety as follows:

Commencing with the Quarter ending on June 30, 2016, the holders of the Series C Preferred Units Outstanding as of an applicable Record Date shall be entitled to receive cumulative distributions (each, a “Series C Quarterly Distribution”), prior to any other distributions made in respect of any Junior Interests pursuant to Section 6.4 or Section 6.5, in the amount set forth in this Section 5.14(b)(ii)(A) in respect of each Outstanding Series C Preferred Unit. All such distributions shall be paid Quarterly within forty-five (45) days after the end of each

1

Quarter (each such payment date, a “Series C Distribution Payment Date”). For the Quarter ending June 30, 2016, and for each Quarter thereafter through and including the Quarter ending September 30, 2017, the Series C Quarterly Distribution on each Outstanding Series C Preferred Unit shall be paid a number of Series C PIK Preferred Units equal to the Series C PIK Payment Amount; provided that, in the discretion of the General Partner which determination shall be made prior to the Record Date for the relevant quarter, the Series C Quarterly Distribution may be paid in cash at the Series C Distribution Rate per Series C Preferred Unit (which, if paid in cash for the Quarter in which the Series C Issuance Date occurs, the amount payable shall be equal to the product of (I) the amount payable without regard to this parenthetical times (II) a fraction, of which the numerator is the number of days from and including the Series C Issuance Date to but excluding the date of such Quarter’s end, and the denominator is 91). With respect to the Quarter ending December 31, 2017 and all Quarters thereafter, the Series C Quarterly Distributions shall be paid entirely in cash at the Series C Distribution Rate per Series C Preferred Unit. If the Partnership establishes a Record Date for any distribution to be made by the Partnership on other Partnership Interests pursuant to Section 6.4 or Section 6.5, then the Record Date established pursuant to this Section 5.14(b)(ii)(A) for a Series C Quarterly Distribution in respect of any Quarter shall be the same Record Date established for any distribution to be made by the Partnership in respect of distributions on other Partnership Interests pursuant to Section 6.4 or Section 6.5 for such Quarter. Unless otherwise expressly provided, references in this Agreement to Series C Preferred Units shall include all Series C PIK Preferred Units Outstanding as of the date of such determination.

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

C. 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 that would apply the laws of any other state.

D. Severability. Each provision of this Amendment shall be considered severable and if for any reason any provision or provisions herein are determined to be invalid, unenforceable or illegal under any existing or future law, such invalidity, unenforceability or illegality shall not impair the operation of or affect those portions of this Amendment that are valid, enforceable and legal.

E. Counterparts. This Amendment may be executed in any number of counterparts, each of which shall be an original, but such counterparts shall together constitute but one and the same instrument.
