ORIENTAL FILES SHELF REGISTRATION FOR CAPITAL PLANNING PURPOSES
AND FLEXIBILITY FOR FUTURE OPPORTUNITIES

SAN JUAN, Puerto Rico, November 20, 2008 — Oriental Financial Group Inc. (NYSE: OFG) yesterday filed a shelf registration statement on Form S-3 with the Securities and Exchange Commission for one or more offerings of common stock, series of preferred stock, and warrants. Oriental said the filing was part of its long-term capital planning in order to gain flexibility going forward as strategic opportunities may arise in Puerto Rico.

Commenting on the filing, Oriental’s President and Chief Executive Officer, José Rafael Fernández, stated, “Our capital ratios remain above regulatory requirements, with risk-based capital ratios significantly above regulatory capital adequacy guidelines. At September 30, 2008, Tier 1 Leverage Capital Ratio was 5.98% (1.5 times the minimum of 4.00%), Tier 1 Risk-Based Capital Ratio was 15.93% (4.0 times the minimum of 4.00%), and Total Risk-Based Capital Ratio was 16.49% (2.1 times the minimum of 8.00%). Consequently, while we are already very well positioned to pursue our current business strategies, the shelf registration will provide us with added financial flexibility should appropriate opportunities present themselves in Puerto Rico. Oriental also has applied for participation in the U.S. Department of the Treasury’s TARP Capital Purchase Program, which, if approved, would entail the issuance of securities that are the subject of the shelf registration.”
