On May 4, 2010, StoneMor Partners L.P. (the “Partnership”) entered into (i) the Sixth Amendment to Amended and Restated Credit Agreement by and among the Partnership, StoneMor GP LLC (the “General Partner”), StoneMor Operating LLC (the “Operating Company”), certain subsidiaries of the Operating Company (together with the Partnership, the General Partner and the Operating Company, the “Credit Parties”), the Lenders identified therein, and Bank of America, N.A., as Administrative Agent (the “Sixth Amendment to Credit Agreement”); and (ii) the Sixth Amendment to Amended and Restated Note Purchase Agreement by and among the Partnership, the General Partner, the Operating Company, certain subsidiaries of the Partnership and the Noteholders (the “Sixth Amendment to NPA”).

The Sixth Amendment to Credit Agreement amended the Amended and Restated Credit Agreement, dated August 15, 2007 (as amended, the “Credit Agreement”) to, among other things, provide that the Partnership and the General Partner shall not permit the Consolidated Leverage Ratio to be greater than:

Under the Credit Agreement, the interest rate on Base Rate Loans and Eurodollar Rate Loans is calculated based on the Base Rate or Eurodollar Rate, as applicable, plus the Applicable Rate. The Sixth Amendment to Credit Agreement amended the definition of Applicable Rate to provide that, commencing on May 4, 2010 until such time as the Agent shall have received a Compliance Certificate evidencing compliance with all financial covenants for the most recently completed four fiscal quarters of the Partnership ending on or after December 31, 2010, Pricing Level 3 of the Applicable Rate (the currently applicable pricing level) for (i) Eurodollar Rate Loans and Letter of Credit Fees shall be increased by 25 basis points to 4.50%, and (ii) Base Rate Loans shall be increased by 25 basis points to 3.50%.

The Sixth Amendment to Credit Agreement also amended the definition of Consolidated EBITDA to provide that Consolidated EBITDA shall not be adjusted for any changes resulting from the sale by the Credit Parties of all of their investments held, as of May 4, 2010, in one of more Merchandise Trusts in the Highland Floating Rate Advantage Fund.

The Sixth Amendment to NPA amended the Amended and Restated Note Purchase Agreement, dated August 15, 2007 (as amended, the “Note Purchase Agreement”) to, among other matters, provide for (i) changes to the Consolidated Leverage Ratio similar to the changes under the Sixth Amendment to Credit Agreement as described above, and (ii) the payment by the Partnership to each holder of Series B Notes and Series C Notes of additional interest at a rate of 0.25% per annum (the “Additional Interest”) from May 4, 2010 until such time as each holder of Notes shall have received a Compliance Certificate for the most recently completed four fiscal quarters of the Partnership ending on or after December 31, 2010 evidencing that the Consolidated Leverage Ratio was less than 3.75 to 1.00 for such period. The Series B Notes and Series C Notes were amended and restated to provide for the payment of the Additional Interest as described in the Sixth Amendment to NPA.

The Sixth Amendment to Credit Agreement and Sixth Amendment to NPA (together, the “Amendments”) also include various representations, warranties and other provisions customary for transactions of this nature. The foregoing is a summary of the material provisions of the Amendments. This summary is not intended to be complete and is qualified in its entirety by reference to the Amendments, which are attached hereto as Exhibits 10.1 and 10.2, respectively, and are incorporated herein by reference.
