Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

On April 2, 2014, StoneMor Operating LLC and certain other subsidiaries of StoneMor Partners L.P. (the “Company”) entered into two Asset Sale Agreements (collectively, the “Agreements”) with certain subsidiaries of Service Corporation International (“SCI”) to acquire nine funeral homes, twelve cemeteries, two crematories and certain related assets (the “Assets”) in Central Florida, North Carolina, Southeastern Pennsylvania and Virginia. The Company was the successful bidder to purchase these properties from SCI. On March 21, 2014, SCI submitted its application to the Federal Trade Commission (“FTC”) to approve the Company’s acquisition of certain of these properties. The bidding and approval process was initiated by SCI in connection with its recently completed acquisition of Stewart Enterprises, Inc. pursuant to an FTC Decision and Order.

In consideration for the transfer of the Assets and in addition to the assumption of certain liabilities pursuant to the Agreements, the Company will pay an aggregate purchase price of $53.8 million, subject to adjustments related to accounts receivable, merchandise trust amounts and endowment care trust amounts.

The closing of the transactions contemplated by the Agreements is subject to the satisfaction of certain closing conditions, including, obtaining all necessary regulatory approvals, including FTC approval, as discussed above, and financing for the purchase price.

SCI can terminate the Agreements if, among other conditions, (i) all regulatory approvals are not obtained by June 30, 2014, subject to certain extensions; or (ii) the Company does not obtain the necessary financing within 20 business days after all regulatory approvals are obtained. If the Agreements are terminated due the Company’s inability to obtain the financing for the purchase price within 20 business days after all regulatory approvals are obtained, and the Company did not use its best efforts to obtain such financing, the Company will be obligated to pay a break-up fee of $1.0 million.

The Agreements also include various representations, warranties, covenants, indemnification and other provisions which are customary for transactions of this nature.

The foregoing summary is not intended to be complete and is qualified in its entirety by reference to the Agreements, which are incorporated by reference in their entirety herein and which are attached to this Current Report on Form 8-K as Exhibits 2.1 and 2.2, respectively.
