On January 24, 2011, StoneMor Partners L.P. (the “Partnership”) entered into Amendment No. 1 (the “Amendment”) to the Omnibus Agreement, dated as of September 20, 2004 with the following entities that are affiliated with the Partnership: MDC IV Trust U/T/A November 30, 2010 (“MDC IV Trust”), MDC IV Associates Trust U/T/A November 30, 2010 (“MDC IV Associates Trust”), Delta Trust U/T/A November 30, 2010 (“Delta Trust,” and collectively with MDC IV Trust and MDC IV Associates Trust, the “Liquidating Trusts”) (successors respectively to McCown De Leeuw & Co. IV, L.P., a California limited partnership (“MDC Fund IV”), McCown De Leeuw IV Associates, L.P., a California limited partnership (“MDC Fund IV Associates”), Delta Fund LLC, a California limited liability company (collectively with MDC Fund IV and MDC Fund IV Associates, the “MDC Funds”) and MDC Management Company IV, LLC, a California limited liability company (“MDCMC”)), Cornerstone Family Services LLC, a Delaware limited liability company, CFSI LLC, a Delaware limited liability company (“CFSI”), StoneMor GP LLC, a Delaware limited liability company (the “General Partner”), for itself and on behalf of the Partnership in its capacity as general partner of the Partnership, and StoneMor Operating LLC, a Delaware limited liability company.

The Amendment clarified that CFSI’s obligations to indemnify and defend the General Partner, the Partnership and any of its subsidiaries from and against any losses relating to certain tax liabilities terminated as of January 24, 2011. In connection with such termination, the Amendment eliminated the requirement that CFSI held assets having an aggregate fair market value of at least $35.0 million with respect to such indemnification obligations.

In addition, each of the MDC Funds entered into a transfer agreement, dated as of November 30, 2010, with MDC IV Trust, MDC IV Associates Trust and Delta Fund Trust, respectively, pursuant to which each of such Liquidating Trusts assumed and agreed to be bound by each of the respective transferor’s duties and obligations under the Omnibus Agreement. The Liquidating Trusts became respective successors of the MDC Funds and MDCMC under the Omnibus Agreement. The parties to the Amendment (other than the Liquidating Trusts) approved, ratified and confirmed such assumption, agreement and succession.

The Amendment also includes various other provisions customary for a transaction of this nature. The foregoing is a summary of the material provisions of the Amendment. This summary is not intended to be complete and is qualified in its entirety by reference to the Amendment, which is attached hereto as Exhibit 10.1 and is incorporated herein by reference.
