Item 1.01.             Entry Into a Material Definitive Agreement.

On February 17, 2015, Acacia Natural Gas Corp I, Inc. (“Acacia”), a wholly-owned subsidiary of EnLink Midstream, LLC (“ENLC”), entered into a Contribution and Transfer Agreement (the “Drop-Down Agreement”) with EnLink Midstream Partners, LP (the “Partnership”), pursuant to which Acacia sold a 25% limited partner interest (the “Transferred Interests”) in EnLink Midstream Holdings, LP (“EMH”), to the Partnership.  The closing of the transactions contemplated by the Drop-Down Agreement occurred simultaneously with the execution of the Drop-Down Agreement.  As consideration for the Transferred Interests, the Partnership issued 31,618,311 Class D Common Units in the Partnership to Acacia (the “Consideration Units”).  After giving effect to the closing of the transactions contemplated by the Drop-Down Agreement, Acacia owns 25% of the total limited partner interests in EMH, with the Partnership indirectly owning the remaining 75% limited partner interest in EMH.

The Partnership’s Class D Common Units are substantially similar in all respects to the Partnership’s Common Units, except that they will only be entitled to a pro rata distribution for the fiscal quarter ended March 31, 2015.  The Partnership’s Class D Common Units will automatically convert into the Partnership’s Common Units on a one-for-one basis on the first business day following the record date for distribution payments with respect to the distribution for the quarter ended March 31, 2015.  The private placement of the Partnership’s Class D Common Units pursuant to the Drop-Down Agreement was made in reliance upon an exemption from the registration requirements of the Securities Act of 1933, as amended, pursuant to Section 4(2) thereof.

Pursuant to the Drop-Down Agreement, the Partnership and Acacia made certain representations and warranties to each other.  Among other representations and warranties, Acacia made representations and warranties to the Partnership regarding title to the Transferred Interests, compliance with laws with regard to Acacia’s ownership of the Transferred Interests and its investment intent with regard to its receipt of the Consideration Units.  The Partnership made representations and warranties to Acacia regarding the accuracy and timeliness of the Partnership’s reporting pursuant to rules and regulations promulgated by the Securities and Exchange Commission (the “Commission”) and the lawfulness of its issuance of the Consideration Units to Acacia.  Acacia and the Partnership also agreed to indemnify each other for breaches of representations and warranties and non-fulfillment of covenants included in the Drop-Down Agreement.

Neither party has the right to assign its rights or obligations under the Drop-Down Agreement, except that the Partnership has the right to assign its rights to any of its direct or indirect subsidiaries or other affiliates.  In connection with the closing of the transactions contemplated by the Drop-Down Agreement, the Partnership assigned its rights to receive the Transferred Interests to EnLink Midstream Operating, LP, its operating subsidiary.

The foregoing description of the Drop-Down Agreement does not purport to be complete and is qualified in its entirety by reference to the text of the Drop-Down Agreement, which is filed as Exhibit 10.1 to this Current Report on Form 8-K (this “Current Report”) and is incorporated herein by reference.
