Item 4

Ownership.







(a)
SCP owns 14,255,101 Units.  Because SCGP, as SCP's general partner, has sole voting power over SCP's security holdings, and SCM, as SCP's invesment manager, has sole power over the investment of SCP's security holdings, each of SCGP and SCM may be deemed to have beneficial ownership of the Units owned of record by SCP.   SCGP thus may be deemed to have beneficial ownership of 14,255,101 Units.

Additionally, SCM owns 45,000 Units for its own account, and shares investment power over another 210,00 Units owned by other investment advisory clients of SCM.  SCM thus may be deemed to have benfeficial ownership of a total of 14,510,101 Units.  Because Mr. Singley controls all voting and investment decisions of SCM and SCGP, he may be deemed to have beneficial ownership of 14,510,101 Units.







(b)
Each of SCP and SCGP may be deemed to have beneficial ownership of 19.8% of the Issuer's outstanding Units.

Each of SCM and Mr. Singley may be deemed to have beneficial ownership of 20.2% of the Issuer's outstanding Units.

These percentages were calculated based on 71,980,216 Units outstanding as of August 14, 2010, as reported in the Issuer's most recent Form10-Q filed with the Securities and Exchange Commission on August 16, 2010.







(c)
With respect to the 14,255,101 Units held by SCP, Mr. Singley has the sole power to vote and dispose or direct the disposition of such Units.

With respect to the 45,000 Units held by SCM for its own account, Mr. Singley has the sole power to vote and dispose or direct the disposition of such Units.

With respect to the 210,000 Units held by other investment advisory clients of SCM, Mr. Singley shares power to dispose or direct the disposition of such Units, but has no power to vote them.
