Cathay General Bancorp Increases Bid for Great Eastern Bank

    LOS ANGELES, Oct. 21 /PRNewswire-FirstCall/ -- Cathay General Bancorp (the
"Company") (Nasdaq: CATY), the holding company for Cathay Bank, announced today
that it had raised its bid for Great Eastern Bank to $5 per share more than
Great Eastern Bank's announced transaction with UCBH Holdings, Inc.
    The Company also announced that it would be willing to enter into a
transaction agreement with Great Eastern Bank that would provide shareholders of
Great Eastern Bank with a greater certainty of consummation than the undisclosed
agreement between Great Eastern Bank and UCBH and on other more favorable terms.
The bid price of the Company's proposal would be fixed at the time of signing
and subject to a maximum of $65. The increased price from the Company is subject
to the same purchase price adjustments contained in Great Eastern's agreement
with UCBH and will be reduced by the amount of any break-up or similar fee that
Great Eastern Bank might be required to pay to UCBH.
    "Prior to their transaction with UCBH, we had informed the Great Eastern
Board that we would be willing to increase our proposed price and cautioned
Great Eastern against entering into a transaction with any other party without
speaking with us first," said Mr. Dunson K. Cheng, Chairman of the Board,
President, and Chief Executive Officer of the Company. "I am disappointed that
Great Eastern Bank entered into a transaction without exploring our expressed
interest in acquiring Great Eastern Bank at a full and fair price. We intend to
fully pursue our options to acquire Great Eastern Bank and we would urge the
Great Eastern Board to work with us to maximize value for all Great Eastern
shareholders."
    The Company has previously announced that it had entered into option
agreements with shareholders of Great Eastern Bank for the right to purchase
approximately 41% of the outstanding shares of Great Eastern Bank. Subject to
regulatory approval, the Company intends to exercise these options and would not
vote in favor of the current transaction between Great Eastern Bank and UCBH,
which requires the approval of holders 66 2/3rds of Great Eastern Bank
shareholders.
    The Company has made regulatory filings to the Federal Reserve Bank of San
Francisco and the New York State Banking Department to acquire up to 100% of the
stock of Great Eastern Bank.
    A copy of the Company's letter to the Board of Great Eastern Bank detailing
the terms of its increased bid follows this news release.

Directors of Great Eastern Bank:

     The Board of Directors
     Great Eastern Bank
     c/o William J. Laraia
     President and Chief Executive Officer
     235 Fifth Avenue
     New York, NY  10016

    Dear Sirs,

     We were surprised and disappointed to see your announcement that you had
entered into a transaction agreement on October 13 with UCBH Holdings, Inc. and
even more so to read that the agreement contains a break-up fee. As set forth in
the letter we sent to you on October 12, we cautioned you that any grant of a
break-up fee would be a waste of corporate assets in light of our willingness to
match any reasonable proposal that you might obtain. To the detriment of your
shareholders, you have rebuffed our every attempt to make any such offer.
    As we have repeatedly informed you, we are extremely interested in acquiring
100% of the equity interests of Great Eastern Bank at a full and fair price to
all of your shareholders. Towards that end, we are hereby increasing our bid to
$5 per share more than your announced transaction with UCBH. Our price would be
fixed at the time of signing and subject to a maximum of $65. Our proposal is
subject to the same purchase price adjustments contained in your transaction
with UCBH and will be reduced by the amount of any break-up or similar fee that
you might be required to pay to UCBH.
    We would be willing to pay the entire purchase price in cash or in cash and
stock in a transaction structured as a tax-free reorganization and would be
willing to allow up to 60% of your shareholders to elect to receive Cathay
shares on a tax-free basis. Unlike your transaction with UCBH, our proposal is
on a




"fixed value" basis, providing certainty to your shareholders and eliminating
their exposure to the vagaries of the stock market and the UCBH stock price.
    While you have chosen not to publicly disclose all of the material terms of
your agreement with UCBH, based on the limited available information concerning
your agreement, we are highly confident that we could enter into a transaction
agreement no less favorable to your shareholders than your agreement with UCBH
and we suspect considerably more favorable. We note that your agreement with
UCBH appears to be highly conditional. We would expect that we would be able to
enter into an acquisition agreement that provides your shareholders with a
greater certainty of consummation.
    Our proposal is subject to confirmatory diligence only and we are confident
that we could rapidly review the same types of diligence information that you
have provided to UCBH. We would of course be willing to enter into a standard
confidentiality agreement with respect to any information you provide us.
    As you know, we are potential owners of more than 40% of your common stock
and have the ability, through the exercise of options and subject to the receipt
of regulatory approval, to disapprove the UCBH transaction (given the 66 2/3%
shareholder approval requirement under New York law and your transaction
agreement). In addition, in light of our proposal, we would expect that few, if
any, of your shareholders are in favor of your continuing to pursue a
transaction with UCBH. We intend in all instances to exercise the options we
presently hold to acquire an approximate 41% interest in Great Eastern.
    In short, our proposal is clearly superior to the UCBH agreement. It
provides your shareholders with significantly higher value and much greater
certainty in realizing that value. We remain interested in acquiring Great
Eastern Bank at a full and fair price. We trust that you will act in the best
interests of your shareholders and work cooperatively with us to enter into a
transaction for the benefit of all of your shareholders.
    Please send us immediately a copy of your transaction agreement with UCBH.
Upon receipt, we will promptly make the appropriate revisions to the agreement
to include the above as well as to reflect other more favorable terms.

     Very truly yours,

     /s/ Dunson K. Cheng

     and Chief Executive Officer
