International Oil & Gas Holdings Corporation Highlights 3-Step Bio-Diesel
Production Process

Each Load of Bio-Diesel Is Lab-Tested to Ensure a Consistent Quality Product
Throughout Manufacturing

DALLAS, Jun 14, 2007 (BUSINESS WIRE) -- International Oil & Gas Holdings
Corporation (Pink Sheets:IOGH) today announced that the Company's proprietary
production processes for bio-diesel made from oils and fats are contained in
three basic routes: Base catalyzed trans-esterification of the feedstock, Acid
catalyzed trans-esterification and Conversion of the feedstock to its fatty
acids, and then to bio-diesel. A major difference in the IOGH process compared to
others is that most bio-diesel today is produced using the Base catalyzed
reaction because of ease of overall production cost. The choice of which Base
catalyst to use can have long range effects on the quality of the bio-diesel
produced. IOGH has chosen and perfected this 3-stage process.

The IOGH system uses a sodium hydroxide catalyst instead of a potassium hydroxide
catalyst to control the chemistry of the end products created during the reaction
process. Both sodium hydroxide and potassium hydroxide dissolve in oils and fats,
and a small amount of excess catalyst is needed to complete the reaction. The
catalyst must be neutralized at the end of the reaction to prevent carryover into
the bio-diesel. Potassium hydroxide will dissolve in the oils and fats faster and
stay dissolved longer than the sodium hydroxide, and at first would sound like
the better choice of catalyst, but potassium hydroxide also creates problems with
the final bio-diesel because it can create an excessive ash content in the burned
fuel, and can lead to engine deposits and high abrasive wear on the pistons and
cylinders.

The IOGH process uses laboratory testing on every tank of bio-diesel to insure
that the quality of the bio-diesel meets the highest standards and that the
catalyst is neutralized into a very safe product known as salt.

"Chemistry is a tool that we use to control every phase of production and
determine the products that we can sell to our customers without creating waste
by-products," stated Rick Graves, President of International Oil and Gas Holdings
Corp.
