ORIENTAL BANK AND TRUST ACQUIRES
THE OPERATIONS OF EUROBANK FROM THE FDIC

TRANSFORMATIVE ACQUISITION INCLUDES EXPECTED DEPOSITS OF APPROXIMATELY
$785 MILLION AND EXPECTED ASSETS OF APPROXIMATELY $1.7 BILLION,
INCREASES BRANCHES TO 43, AND BROADENS MARKET OPPORTUNITIES

SAN JUAN, PUERTO RICO, April 30, 2010 — Oriental Financial Group Inc. (the “Company”) (NYSE: OFG) today announced that its commercial bank subsidiary, Oriental Bank and Trust (“Oriental”), has acquired all of the retail deposits and substantially all of the assets and operations of Eurobank from the Federal Deposit Insurance Corporation, as receiver of Eurobank.

José Rafael Fernández, President, CEO and Vice Chairman of the Board of the Company, said “this transaction helps restore normalcy to the Puerto Rico banking industry and represents a transformative event for Oriental — one that maintains Oriental’s historic financial strength while providing new growth opportunities. This transaction significantly enhances Oriental’s position in Puerto Rico and is very much in line with our strategy to expand the integrated delivery of our services to mid and high net worth clients, and to increase our mix of loans relative to investment securities.”

“We warmly welcome our new customers — the consumers and businesses previously served by Eurobank,” continued Mr. Fernández. “From your point of view, it will be business as usual. Your deposits are now held in a well capitalized bank with a 46-year history of strength, service and stability. And your deposits remain insured by the FDIC to the fullest extent permitted by law. We are also very excited to welcome Eurobank’s employees to the Oriental team.

“Oriental has a culture that treasures its customer relationships. We pride ourselves in helping our customers manage their finances through Oriental’s advisory model of delivery. We are flexible and nimble in our service delivery. And we employ advanced technology that enables us to provide for smooth and efficient operations. Representatives of Oriental are at all branches to assist you, should you have any questions.”

Under Oriental’s agreement with the FDIC, Oriental assumed expected deposits of approximately $785 million and expected assets of approximately $1.7 billion, including an approximately $1.58 billion loan portfolio which will be subject to a loss sharing arrangement pursuant to which the FDIC will bear 80% of qualifying losses. As part of this transaction, the Company issued to the FDIC a value appreciation instrument. Additionally, Oriental will issue to the FDIC a promissory note in the amount of approximately $715.5 million to be repaid within one year of closing, subject to up to 4 one-year renewals. The note covers a portion of the excess of assets acquired over the liabilities assumed, rather than requiring Oriental to pay cash for such amount. The remaining amount of such excess, which is expected to be approximately $100 million, will be paid in cash.

The Company and Oriental were advised on this transaction by Keefe, Bruyette & Woods, Inc., as financial advisor, and Skadden, Arps, Slate, Meagher & Flom LLP and McConnell Valdés LLC, as legal advisors.

Eurobank customers who have questions about today’s transaction can call the FDIC toll-free at 1-800-591-2903. The phone number will be operational this evening until 9:00 p.m., Atlantic Standard Time (AST); on Saturday from 9:00 a.m. to 6:00 p.m., AST; on Sunday from noon to 6:00 p.m., AST; and thereafter from 8:00 a.m. to 8:00 p.m., AST.
