Open Solutions' Chairman and CEO, Louis Hernandez, Jr. said, "Overall, we are very pleased with the solid performance that we recorded in the first quarter of 2004. We maintained our momentum from 2003 and exceeded our first quarter of 2004 revenue and net income guidance by approximately $1.2 million and $200,000, respectively. We continued to achieve strong results across the board in the face of a highly competitive and challenging economic environment. Our growth in business is a direct reflection of our proven ability to continually offer quality client service, innovative products and unwavering focus on meeting the dynamic needs of the financial services sector.

Signed contracts valued at $15.5 million in the first quarter of 2004 compared to $14.6 million in the same quarter of the prior year. We define contract value as total revenues to be received over the life of the contract for all elements, including all license, hardware, installation, maintenance and other services.

Recurring revenue for the first quarter 2004 increased to 49 percent of total revenue from 46 percent for the first quarter of 2003. We define recurring revenue as revenue from long-term maintenance and data center hosting contracts and the quarterly minimum payments from BISYS.

Internal revenue growth for the first quarter 2004 compared to the first quarter 2003 was 43 percent. Internal revenue growth percentages are measured as the increase in revenue for the current period less "acquired revenue from acquisitions" divided by revenues from the prior period plus "annualized revenue from acquisitions". The "acquired revenue from acquisitions" for the first quarter was $3.3 million and there was no "annualized revenue from acquisitions" for the prior quarter.

2004 Business Outlook

The following statements are forward looking and actual results may differ materially. Our guidance assumes no change in the calculation of the Company's tax provision, which currently assumes a full valuation allowance against the Company's deferred tax assets. Currently, the Company only records a charge against income for certain state taxes and federal alternative minimum taxes. At the time that the valuation allowance is released the Company will report a significant income tax benefit in that period and for subsequent periods will record a tax provision against income at the effective statutory rates, however, the Company does not expect to incur significant tax payments until all anticipated net operating loss carry forwards and research and development tax credits are utilized.

Second Quarter 2004

The Company targets revenue to be between $20.5 million and $21.2 million, net income to be between $3.0 million and $3.3 million and earnings per diluted share to be between $0.16 and $0.17.

Full year 2004

The Company targets revenue to be between $85.0 million and $89.0 million, net income to be between $15.4 million and $15.8 million and earnings per diluted share to be between $0.81 and $0.83, an increase over previous guidance of between $84.0 million and $88.0 million for revenue, $15.2 million and $15.5 million for net income and $0.80 and $0.82 earnings per diluted share.
