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 August 4, 2016, StoneMor Operating LLC (the “Operating Company”), a wholly-owned subsidiary of StoneMor Partners L.P. (the “Partnership”), entered into the Credit Agreement (the “Credit Agreement”) among each of the Subsidiaries of the Operating Company (together with the Operating Company, “Borrowers”), the Lenders identified therein, Capital One, National Association (“Capital One”), as Administrative Agent, Issuing Bank and Swingline Lender, Citizens Bank of Pennsylvania, as Syndication Agent, and TD Bank, N.A. and Raymond James Bank, N.A., as Co-Documentation Agents. In addition, on the same date, the Partnership, the Borrowers and Capital One, as Administrative Agent, entered into the Guaranty and Collateral Agreement (the “Guaranty Agreement,” and together with the Credit Agreement, “New Agreements”).

The New Agreements replaced the Partnership’s Fourth Amended and Restated Credit Agreement, as amended with Bank of America, N.A., as Administrative Agent, Swing Line Lender and L/C Issuer and other lenders party thereto (the “Prior Credit Agreement”), Second Amended and Restated Security Agreement, and Second Amended and Restated Pledge Agreement, each dated as of December 19, 2014 (collectively, “Prior Agreements”). The Prior Credit Agreement provided for a revolving credit facility of $180.0 million, with borrowings classified as either acquisition draws or working capital draws, maturing on December 19, 2019.

The summary of the material terms of the New Agreements is set forth below. Capitalized terms which are not defined in the following description shall have the meaning assigned to such terms in the New Agreements.

The Credit Agreement provides for up to $210.0 million initial aggregate amount of Revolving Commitments, which may be increased, from time to time, in minimum increments of $5.0 million so long as the aggregate amount of such increases does not exceed $100.0 million. The Operating Company may also request the issuance of Letters of Credit for up to $15.0 million in the aggregate. The Maturity Date under the Credit Agreement is the earlier of (i) August 4, 2021 and (ii) the date that is six months prior to the earliest scheduled maturity date of any outstanding Permitted Unsecured Indebtedness (at present, such date is December 1, 2020, which is six months prior to June 1, 2021 maturity date of outstanding 7.875% senior notes).

As of August 4, 2016, the outstanding amount of borrowings under the Credit Agreement was $126.1 million, which was used to (i) pay down outstanding obligations under the Prior Credit Agreement and (ii) pay fees, costs and expenses related to the New Agreements. Generally, proceeds of the Loans under the Credit Agreement can be used to finance the working capital needs and for other general corporate purposes of the Borrowers and Guarantors, including acquisitions and distributions permitted under the Credit Agreement.

Each Borrowing under the Credit Agreement is comprised of Base Rate Loans or Eurodollar Loans. The Loans comprising each Base Rate Borrowing (including each Swingline Loan) bear interest at the Base Rate plus the Applicable Rate, and the Loans comprising each Eurodollar Borrowing bear interest at the Eurodollar Rate plus the Applicable Rate.

The Applicable Rate is determined based on the Consolidated Leverage Ratio of the Partnership and its Subsidiaries and ranges from 1.75% to 3.25% for Eurodollar Rate Loans and 0.75% to 2.25% for Base Rate Loans. As of August 4, 2016, the Applicable Rate for Eurodollar Rate Loans was 2.75% and for Base Rate Loans – 1.75%. The Credit Agreement also requires the Borrowers to pay a quarterly unused commitment fee, which accrues at the Applicable Rate on the amount by which the commitments under the Credit Agreement exceed the usage of such commitments.

The Credit Agreement contains financial covenants, pursuant to which the Partnership will not permit:

Additional covenants include customary limitations, subject to certain exceptions, on, among others: (i) the incurrence of Indebtedness; (ii) granting of Liens; (iii) fundamental changes and dispositions; (iv) investments, loans, advances, guarantees and acquisitions; (v) swap agreements; (vi) transactions with Affiliates; (vii) Restricted Payments; and (viii) Sale and Leaseback Transactions.

Events of Default under the Credit Agreement include, but are not limited to, the following:

The Borrowers’ obligations under the Credit Agreement are guaranteed by the Partnership and the Borrowers. Pursuant to the Guaranty Agreement, the Borrowers’ obligations under the Credit Agreement are secured by a first priority lien and security interest (subject to permitted liens and security interests) in substantially all of the Partnership’s and Borrowers’ assets, whether then owned or thereafter acquired, excluding certain excluded assets, which include, among others: (i) Trust Accounts, certain proceeds required by law to be placed into such Trust Accounts and funds held in such Trust Accounts; and (ii) Excluded Real Property, including owned and leased real property that may not be pledged as a matter of law.

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

Some of the lenders and their respective affiliates under the Credit Agreement acted as lenders under the Prior Credit Agreement. In addition, some of the lenders under the Prior Credit Agreement and the Credit Agreement engaged in, and may in the future engage in, investment banking and other commercial dealings with the Partnership and its affiliates for which they received, and will receive, customary fees and expenses.

The foregoing summary of the New Agreements is not complete and is qualified in its entirety by reference to the New Agreements, which the Partnership intends to file with the Securities and Exchange Commission as exhibits to the Quarterly Report on Form 10-Q for the quarter ending September 30, 2016.

In connection with entering into the Credit Agreement, the Partnership incurred an extinguishment of debt charge of approximately $1.2 million.
