HOUSTON AMERICAN ENERGY ANNOUNCES FIRST QUARTER 2010 FINANCIAL RESULTS

HOUSTON AMERICAN ENERGY ANNOUNCES FIRST QUARTER 2010 FINANCIAL RESULTS — Company Declares Quarterly Dividend of $.005 per Share —
Houston, Texas – May 7, 2010 – Houston American Energy Corp. (Nasdaq: HUSA) today reported its financial results for the quarter ended March 31, 2010.

The Company reported net income for the three months ended March 31, 2010 of $808,716, or $0.03 per share, on revenues of $4,241,395, as compared to a loss of $1,478,320, or ($0.05) per share, on revenues of $445,142 for the three months ended March 31, 2009. The increase in revenue for the quarter was primarily attributable to increased volumes in our Colombia operations coupled with increased commodity prices realized in the 2010 quarter as compared to 2009. Mr. John F. Terwilliger, President and Chairman of Houston American Energy, stated, “Houston American Energy’s oil and gas revenues in the first quarter showed a 853% improvement over the first quarter of 2009, and production showed an 326% improvement versus the volumes sold during the first quarter of 2009. Our success in bringing new wells onto production and improvement in commodity pricing has fueled our strong bounce back in production and in operating results from the 2009 quarter when severely depressed commodity prices resulted in a temporary cessation of production from the majority of our wells in Colombia. Continuing that trend, the second quarter of this year is off to a great start as well, such that oil and gas revenues achieved just in April are over 2 times the revenue Houston American earned for the entire second quarter of 2009. Also, I feel it is important to point out that we spent over $4,000,000 in the first quarter on our oil and gas properties, yet our cash balances have slightly grown to more than $14.05 million as of the date of this release, exceeding our year-end 2009 cash balances. I am very pleased with the achievements in our cost controls, revenue growth and the improvements in liquidity made so far this year. In the very near term we expect to report the results of previously announced efforts to market a portion of our Colombian assets.”

In view of the Board of Directors’ confidence in the outlook for Houston American Energy, a dividend of $0.005 per share has been declared for shareholders of record as of May 26, 2010 with a payment date of June 16, 2010.
