FOR IMMEDIATE RELEASE

Callon Petroleum Company Reports 25% Increase in Net Income

Natchez, MS (May 7, 2008)—Callon Petroleum Company (NYSE: CPE) today reported results of operations for the quarter ended March 31, 2008.

 First Quarter 2008 Net Income.  For the quarter ended March 31, 2008, the company reported net income of $7.6 million, or $0.35 per share, a 25% increase over net income of $5.8 million, or $0.27 per share, for the same period in 2007.

           First Quarter 2008 Operating Results.  First quarter 2008 oil and gas sales totaled $45.0 million from production of 42.1 million cubic feet of natural gas equivalent per day (MMcfe/d).  This corresponds to sales of $45.5 million from production of 60.3 MMcfe/d during the same period in 2007.  The average price received per thousand cubic feet of natural gas in the first quarter of 2008 increased to $9.50, compared to $7.97 during the first quarter of 2007, while the average price received per barrel of oil in the first quarter of 2008 increased to $86.66, compared to $55.53 during the same period in 2007.  All average realized price amounts are after the impact of hedging.

First Quarter 2008 Discretionary Cash Flow. Discretionary cash flow for the quarter ended March 31, 2008 totaled $29.0 million compared to $33.5 million during the previous year.  Net cash flow provided by operating activities, as defined by GAAP, totaled $35.1 million and $32.9 million during the quarters ended March 31, 2008 and 2007, respectively. (See “Non-GAAP Financial Measure” that follows and the accompanying reconciliation of discretionary cash flow to net cash flow provided by operating activities.)

Non-GAAP Financial Measure - This news release refers to a non-GAAP financial measure as “discretionary cash flow.” Callon believes that the non-GAAP measure of discretionary cash flow is useful as an indicator of an oil and gas exploration and production company’s ability to internally fund exploration and development activities and to service or incur additional debt.  The company also has included this information because changes in operating assets and liabilities relate to the timing of cash receipts and disbursements which the company may not control and may not relate to the period in which the operating activities occurred. Discretionary cash flow should not be considered an alternative to net cash provided by operating activities or net income as defined by GAAP.
