First Lien Credit Facility

On September 30, 2004, the Company entered into a Second Amended and Restated Credit Agreement with Hibernia National Bank and Union Bank of California, N.A. (the “First Lien Credit Facility”), which was to mature on September 30, 2007. The First Lien Credit Facility provided for (1) a revolving line of credit of up to the lesser of the Facility A Borrowing Base and $75.0 million and (2) a term loan facility of up to the lesser of the Facility B Borrowing Base and $25.0 million (subject to the limit of the borrowing base, which was $22.5 million as of March 31, 2006). It was secured by substantially all of the Company’s assets and was guaranteed by the Company’s subsidiary, CCBM, Inc. On May 25, 2006, the Company terminated the First Lien Credit Facility upon entering into the Senior Credit Facility (discussed below).

Second Lien Credit Facility

On July 21, 2005, the Company entered into a Second Lien Credit Agreement with Credit Suisse, as administrative agent and collateral agent (the “Agent”) and the lenders party thereto (the “Second Lien Credit Facility”) that matures on July 21, 2010. The Second Lien Credit Facility provides for a term loan facility in an aggregate principal amount of $150.0 million. It is secured by substantially all of the Company’s assets and is guaranteed by the Company’s subsidiaries. The liens securing the Second Lien Credit Facility were second in priority to the liens securing the First Lien Credit Facility prior to its termination in May 2006, as discussed above, and are second in priority to the liens securing the Senior Credit Facility (discussed below).

On December 20, 2006, the Company, entered into an amendment, effective as of December 19, 2006, to the Second Lien Credit Facility (the “December 2006 Amendment”). The amendment increased the principal amount available for borrowings under the Second Lien Credit Facility from $150 million to $225 million. The amendment also included the following, without limitation: (1) a reduction in the interest rate on each Eurodollar loan such that it is the adjusted LIBO rate plus a margin of 4.75%; (2) a reduction in the interest rate on each base rate loan such that it is (i) the greater of the Agent’s prime rate and the federal funds effective rate plus 0.5%, plus (ii) a margin of 3.75%; (3) an adjustment to the minimum quarterly interest coverage ratio such that it is 2.75 to 1.0 through and including December 31, 2007 and 3.0 to 1.0 thereafter; (4) an adjustment to the minimum quarterly proved reserve coverage ratio such that it is 1.5 to 1.0 through December 31, 2007 and 2.0 to 1.0 thereafter; and (5) a maximum total net recourse debt to EBITDA ratio of not more than 3.75 to 1.0 through December 31, 2007 and 3.25 to 1.0 thereafter.

The interest rate on each base rate loan will be the greater of the Agent’s prime rate and the federal funds effective rate plus 0.5%, plus a margin of 3.75%. The interest on each Eurodollar loan will be the adjusted LIBO rate plus a margin of 4.75%. Interest on Eurodollar loans is payable on either the last day of each period or every three months whichever is earlier. Interest on the Company’s outstanding borrowings under the Second Lien Credit Facility is payable quarterly. On December 31, 2006, the interest rate was approximately 10.11%, excluding the impact of interest rate swaps.

The Company is subject to certain covenants under the amended terms of the Second Lien Credit Facility. These covenants include, but are not limited to, the maintenance of the following financial covenants: (1) a minimum current ratio of 1.0 to 1.0 including availability under the borrowing base under the Senior Credit Facility; (2) a minimum quarterly interest coverage ratio of 2.75 to 1.0 through December 31, 2007 and 3.0 to 1.0 thereafter; (3) a minimum quarterly proved reserve coverage ratio of 1.5 to 1.0 through December 31, 2007 and 2.0 to 1.0 thereafter; and (4) a maximum total net recourse debt to EBITDA (as defined in the Second Lien Credit Facility) ratio of not more than 3.75 to 1.0 through December 31, 2007 and 3.25 to 1.0 thereafter.

The Second Lien Credit Facility also places restrictions on additional indebtedness, dividends to shareholders, liens, investments, mergers, acquisitions, asset dispositions, repurchase or redemption of the Company’s common stock, speculative commodity transactions, transactions with affiliates and other matters.

The Second Lien Credit Facility is subject to customary events of default. Subject to certain exceptions, if an event of default occurs and is continuing, the Agent may accelerate amounts due under the Second Lien Credit Facility (except for a bankruptcy event of default, in which case such amounts will automatically become due and payable). If an event of default occurs under the Second Lien Credit Facility as a result of an event of default under the Senior Credit Facility, the Agent may not accelerate the amounts due under the Second Lien Credit Facility until the earlier of 45 days after the occurrence of the event resulting in the default and acceleration of the loans under the Senior Credit Facility.

As of December 31, 2006, the Company had $147.8 million of borrowings outstanding under the Second Lien Credit Facility. Maturities of long-term debt are $1.5 million in each of the years 2007 through 2009 and the balance of $184.3 million is due in 2010. In January 2007, the Company drew the additional $75.0 million in borrowings and received net proceeds of $72.1 million related to the December 2006 Amendment.
