Relational Sues Sovereign and Santander; Alleges Pennsylvania Law Obligates Santander to Pay ``Fair Value'' to All Shareholders.

SAN DIEGO -- Relational Investors LLC, the largest shareholder of Sovereign Bancorp, Inc. (NYSE: SOV), announced today that it has filed a lawsuit in U.S. District Court for the Southern District of New York against Sovereign Bancorp, Inc. and Banco Santander Central Hispano, S. A. (NYSE: STD).

The lawsuit maintains that the proposed transaction between Sovereign and Santander will give Santander (either alone or in concert with others) voting power over 20% or more of Sovereigns' common stock and, therefore, constitutes a "control transaction" under the Pennsylvania Business Corporation Law. As a result, if Santander closes the investment, the law will require Santander to pay all Sovereign shareholders who wish to sell their shares cash equal to "fair value" (including a control premium and interest) based on a court-appointed appraiser's determination. Relational believes that there is powerful evidence for the appraised "fair value" to be substantially more than the $27 price Santander has agreed to pay.

In commenting on the suit, Ralph V. Whitworth, Principal of Relational Investors, said: "In the post Sarbanes-Oxley world, Sovereign's attempt to disenfranchise its shareholders is unprecedented. Fortunately, Pennsylvania Law gives shareholders who object to these coercive conditions, the right to receive the true 'fair value' for their shares."

The suit seeks a declaratory judgment that Santander, alone or in concert with others, will obtain 20% or more of the voting power of Sovereign and that the closing of the amended investment agreement constitutes a control transaction under the Pennsylvania Business Corporation Law. As a result, Relational contends that Santander is obligated to provide written notice to all Sovereign shareholders advising them of their rights to receive fair value for their shares "including...any value payable for acquisitions of control of the corporation..."
