For Immediate Release

Astoria Financial Corporation and Long Island Bancorp, Inc. to Merge

Strategic Alliance Creates $17 Billion Financial Institution; No. 2 Deposit
Market Share Ranking on Long Island

LAKE SUCCESS, N.Y., April 3, 1998 -- Astoria Financial Corporation
(Nasdaq: ASFC) ("Astoria"), and Long Island Bancorp, Inc. (Nasdaq: LISB)
("LISB") jointly announced today that they have signed a definitive
agreement for Astoria and LISB to merge in a tax-free exchange of common stock.
Astoria Financial Corporation, the holding company for Astoria Federal Savings
and Loan Association ("Astoria Federal"), with assets of $10.5 billion and
deposits of $6.2 billion at December 31, 1997, is the third largest thrift
institution in New York and tenth largest in the United States. Astoria Federal
operates 61 banking offices, of which 53 are located in Brooklyn, Queens, Nassau
and Suffolk Counties on Long Island, and eight are located in Westchester County
and upstate New York. LISB is the parent company of The Long Island Savings
Bank, FSB ("Long Island Savings"), a federally chartered thrift institution with
assets of $6.1 billion and deposits of $3.7 billion at December 31, 1997,
headquartered in Melville, Long Island. Long Island Savings operates 35 banking
offices throughout Queens, Nassau and Suffolk Counties and 22 loan production
offices located in 7 states. Upon completion of the transaction, LISB will merge
into Astoria and Long Island Savings will merge into Astoria Federal. The
transaction, which received the unanimous approval of the boards of directors of
Astoria and LISB, will be accounted for as a pooling of interests and will be
accretive to Astoria's earnings per common share in 1999. The transaction is
expected to close at the end of the third quarter of 1998. 

Under the terms of the agreement, holders of LISB common stock will receive 1.15
shares of the common stock of Astoria for each share of LISB common stock. Using
Astoria's average closing stock price for the last five business days ending
April 2, 1998, of $61.78, the exchange represents a price of $71.04 for each
LISB share, approximately 3.09 times LISB's tangible book value at December 31,
1997. The total transaction value is estimated to be $1.8 billion based on
LISB's diluted shares including ESOP shares at Astoria's average stock price for
the last five business days. The pro forma combined company will receive the
proceeds, if any, from the supervisory goodwill lawsuits of LISB and Astoria. As
a result, in addition to the value of the Astoria common stock received, LISB
shareholders, as shareholders of Astoria, will retain an interest in the LISB
supervisory goodwill lawsuit, which if valued consistent with currently traded
market instruments, would approximate $9 - $12 per LISB share, and gain an
interest in the Astoria supervisory goodwill lawsuit. Astoria shareholders, in
addition to current market value, will gain an interest in the LISB supervisory
goodwill lawsuit valued, consistent with currently traded market instruments, at
$8 - $11 per share. Based upon the currently outstanding LISB shares of common
stock, it is expected that approximately 27.6 million new shares of Astoria
common stock will be issued in conjunction with the transaction, bringing the
pro forma 



market capitalization of the combined company to $3.25 billion, the sixth
largest thrift market capitalization nationally. 

The pro forma combined company, as of December 31, 1997, reflects total assets
of $16.6 billion, ranking Astoria the second largest publicly traded thrift
institution in New York and sixth largest nationally. It also includes strong
mortgage origination capabilities in 7 states, deposits totaling $10.0 billion
and shareholders' equity of $1.5 billion. The pro forma company will operate 96
banking offices, including 88 in the New York City metropolitan area: 31 in
Nassau, 20 in Queens, 11 in Brooklyn, and 26 in Suffolk, as well as 3 in
Westchester County and 5 in the upstate counties of Chenango and Otsego.
Subsequent to the closing of the transaction, management anticipates that it
will consolidate six banking offices in communities in which both Astoria and
LISB have a presence. 

Commenting on the transaction, George L. Engelke, Jr., Chairman, President and
Chief Executive Officer of Astoria said, "This strategic alliance between two
strong Long Island financial institutions forms the premier consumer- oriented
community bank on Long Island. The pro forma deposits of the 88 Long Island
banking offices total $9.4 billion, or an average of $107 million per banking
office, resulting in a pro forma #2 market share of deposits and a 8.7% market
share in a market larger in population than 39 states in the United States. We
are confident that the transaction will not only enhance shareholder value, but
also provide long-term benefits for our customers and, particularly, our
communities. We are also delighted that John J. Conefry, Jr., whose leadership
has successfully guided LISB to its current well- capitalized and prominent
position in the Long Island market, will be joining the Board of Directors of
both Astoria Financial Corporation and Astoria Federal Savings and Loan
Association as a Vice Chairman and will also join our executive management team.
His broad knowledge and experience will serve Astoria well as we continue to
implement strategies to build our franchise, strengthen efforts in our
communities, particularly in providing banking and home mortgage expertise to
better serve the financial needs of low-to-moderate income families and
individuals, and enhance shareholder value. We also look forward to adding many
other talented Long Island Savings officers and employees to the already strong
team at Astoria. Four other current directors of LISB will also join both boards
of Astoria." 

Mr. Conefry commented, "We are very excited to be partnering with Astoria, a
premier community-oriented financial services institution. The combination of
our two strong companies will create a powerful retail banking franchise in Long
Island that will provide greater potential for its shareholders, customers and
communities than either institution would provide alone." 

Astoria estimates that operational efficiencies generated as a result of the
transaction will produce cost savings equal to 50%, or approximately $52.0
million, pre-tax, of LISB's estimated 1998 general and administrative expense.
Mr. Engelke, commenting on the estimated cost savings said, "We have a proven
track record of rapidly consolidating back office systems and quickly
recognizing all anticipated cost savings, as evidenced by the speed with which
we successfully integrated The Greater New York Savings Bank (1997) and Fidelity
New York, FSB (1995) into Astoria, allowing us to recognize a substantial part
of all cost savings in the 90 days following the closing of those transactions.
We expect to approach this transaction in the same manner as our past successes
by effecting at least 75% of all anticipated cost savings by the 

                                          2


end of the fourth quarter of 1998 and the balance during the first half of
1999." One-time charges in conjunction with this transaction, anticipated to be
recorded in the fourth quarter, are expected to approximate $75 million, after-
tax. 

In connection with the transaction, there is a provision for a termination fee
of $60 million payable to Astoria if the transaction is not completed under
certain circumstances. In addition, LISB and Astoria have granted cross options
to purchase shares equal to 19.9% of each other's currently outstanding common
stock under certain conditions. Stock repurchase plans have been terminated by
both companies. 

The transaction is subject to approval of the shareholders of both LISB and
Astoria, approval of the Office of Thrift Supervision and the satisfaction of
certain other conditions.
