International Oil & Gas Holdings Corporation's Proprietary Production Process
Adheres to Strict Quality Control Standards

Every Tanker of IOGH Bio-Diesel is Lab Tested and Issued a Certificate of Quality

DALLAS, Jun 12, 2007 (BUSINESS WIRE) -- International Oil & Gas Holdings
Corporation (Pink Sheets:IOGH) today announced that the Company's proprietary
process has the strictest Quality Control standards in the industry.

"We pride ourselves in never having a bad batch of bio-diesel," stated IOGH
President Rick Graves.

Quality control at each step of bio-diesel production is one way that IOGH can
meet the highest standard for its customers. Testing of incoming feedstock allows
IOGH to make use of a wide variety of oils and fats for conversion into
bio-diesel.

Excess amounts of free fatty acids or water can create side products such as soap
which leads to incomplete separation of the glycerin generated during bio-diesel
production. If this is not controlled early in the production process, the
resulting bio-diesel will not meet the minimum ASTM standards. The resulting "bad
bio-diesel" is then typically treated in one of three ways: the bio-diesel is
reprocessed (doubling the cost), blended with other bio-diesel to mask the
problem, or becomes a disposal problem.

The IOGH process uses testing on every tank of bio-diesel to insure quality
during production and then runs a complete set of ASTM (American Society for
Testing and Materials) D6751 Test for bio-diesel from an independent lab. A
Certificate of Quality is provided with each load of bio-diesel produced and
sold. IOGH is setting new standards for production and distribution of the
highest quality bio-diesel within the industry.
