            HAVEN BANCORP, INC. TO MERGE INTO QUEENS COUNTY BANCORP,
                    FORMING NEW YORK COMMUNITY BANCORP, INC.;
  $196 MILLION TRANSACTION EXPECTED TO GENERATE DOUBLE-DIGIT EARNINGS ACCRETION

Queens, N.Y., June 27, 2000 - Queens County Bancorp, Inc. (Nasdaq: QCSB) and
Haven Bancorp, Inc. (Nasdaq: HAVN) today announced the signing of a definitive
agreement under which Haven will merge into Queens County Bancorp, Inc. in a
transaction valued at approximately $196 million.

Under the terms of the agreement, which has been unanimously approved by the
Boards of Directors of both companies, Haven Bancorp shareholders are expected
to receive 1.04 shares of Queens County Bancorp common stock in exchange for
each share of Haven Bancorp stock. The transaction, which is tax-free to Haven's
shareholders, values each share of Haven Bancorp at $18.85, based on Queens
County Bancorp's closing price of $18.125 on June 27, 2000.

The combined entity, to be named New York Community Bancorp, Inc. (and traded on
Nasdaq under the symbol "NYCB"), will have assets of approximately $5.1 billion
and deposits of approximately $3.2 billion prior to a planned restructuring.
Upon completion of the merger, the pro forma company will have a network of 19
traditional branch offices and three customer service centers serving Queens and
Nassau counties, and 62 supermarket branches extending throughout the New York
metropolitan area. In Queens, the company will command an 8% share of the
market, ranking third among thrifts. The traditional branches and customer
service centers will operate under the Queens County Savings Bank banner; the
supermarket branches will continue to operate under the name of CFS Bank.

According to Joseph R. Ficalora, Chairman, President, and Chief Executive
Officer of Queens County Bancorp, Inc., who will serve as Chairman, President,
and Chief Executive Officer of NYCB, it is currently expected that the New
Jersey and Connecticut supermarket branches will be sold. There are no plans to
sell or close any of the traditional branch offices or customer service centers.

- -------------------------------------------------

The transaction is expected to close in the fourth quarter of 2000, subject to
shareholder and regulatory approvals, and will be accounted for using the
purchase method of accounting. Queens County will repurchase up to 20% of the
shares to be issued in the transaction, and may, under certain circumstances,
purchase shares of Haven prior to closing.

Commenting on the merger, Mr. Ficalora stated, "This transaction marries a
proven deposit generator--Haven--with a proven generator of high quality
assets--Queens County. The case for the combination is compelling, and the new
institution will build upon the respective strengths of the individual entities.
With an 80% pro forma ratio of loans to deposits, there will be significant
opportunity for us to expand our profitable multi-family lending, while at the
same time reaping the benefits of Haven's fee generation capabilities.

"The merger is expected to be approximately 25% accretive to earnings in 2001,"
added Mr. Ficalora, "reflecting an estimated annual cost savings of $14.0
million, or $8.5 million after-tax, equivalent to 20% of Haven's annualized core
operating expense. The combined company will record approximately $31.0 million
in pre-tax merger-related charges, which will be reflected in goodwill.

"As a result of the purchase transaction, Haven's loan and securities portfolios
will be marked to market, providing us with the flexibility to restructure the
balance sheet," Mr. Ficalora said. "Approximately $1.0 billion of one-to-four
family loans and securities are expected to be sold following the merger, and
the proceeds used to reduce the combined company's funding costs. We believe
that this strategy establishes a foundation for significant earnings growth at
NYCB in 2001 and beyond."

Haven's Chairman and Chief Executive Officer Philip Messina added, " We believe
that this strategic transaction with Queens County Bancorp is an excellent
opportunity for Haven shareholders. Recognized as the top performing thrift in
the nation, Queens County is a respected financial institution with an
attractive currency, a strong dividend, and a commitment to the core marketplace
we serve. We look forward to working with Queens County toward a smooth
transition."

It is anticipated that three current members of the Haven Board of Directors
will be named to the Board of NYCB. Upon completion of the merger, William J.
Jennings II, President and Chief Operating Officer of Haven, and Dennis Hodne,
Haven's Senior Vice President, Retail Banking, will join the NYCB executive
management team.

New York Community Bancorp will be headquartered in Westbury, New York at
Haven's current executive offices. Commenting on the proposed move to Long
Island, Mr. Ficalora noted, "Earlier this quarter, Queens County Bancorp
negotiated a transaction calling for the sale of its executive office building
to the developer who previously contracted to acquire the adjacent parking lot,
for a pre-tax gain of approximately $14.0 million. The move to Haven's
headquarters will enable us to realize both tax and operating benefits. At the
same time, we will reap the benefits of the sale of our Main Street property."
Arrangements have been made to relocate the Bank's main branch in Flushing to a
commercial banking office on Roosevelt Avenue, one block away.

In connection with the merger agreement, Haven issued a stock option to Queens
County to purchase, under certain circumstances, up to 19.9% of Haven's common
stock.
