FIRST QUARTER 2005 RESULTS

Strategic merger boosts revenue increase of over 320%

SCOTTSDALE, ARIZONA, May 16, 2005 — OneSource Technologies, Inc. (OTCBB: OSRC), a premier-provider of equipment maintenance services to large, national customers in the financial services industry and a source for equipment sales and leasing, today reported profitable results and a significant increase in revenue for its first quarter ended March 31, 2005.

For the first quarter 2005, net income was $61,291 compared to first quarter 2004 when the company experienced a loss of $4,538. Revenue during the three-month period ended March 31, 2005, increased 323% to $3,277,587 from the prior year 2004 period when revenue was $774,408. The significant increase in revenue is the result of the strategic merger in November 2004 with First Financial Computer Services.

“We are very pleased with our positive results for the first quarter 2005 and our progress in completing the majority of our integration process with First Financial, which we anticipate will be completed within the second quarter,” said Michael L. Hirschey, chief executive officer of OneSource Technologies. “We saw a favorable shift in the composition of our revenue with a larger percentage derived from annual maintenance contracts versus equipment and supplies sales. In addition, revenue from sales of equipment and supplies more than doubled in the first quarter with opportunity for continued growth in this area as a result of our much expanded client base.

“We are exploring new opportunities for internal growth and growth from acquisitions that either open new markets or are complementary to our existing operations. We will actively pursue those targets that meet our market requirements, which includes the enhancement of shareholder value,” Hirschey concluded.
