Dear Stockholder:
 
     On behalf of the Board of Directors, it is with great pleasure that I
extend to you a cordial invitation to attend a Special Meeting of Stockholders
of Astoria Financial Corporation ("AFC"). The Special Meeting will be held on
August 1, 1997, at 9:30 a.m., Eastern Time, at the New Hyde Park Inn, 214
Jericho Turnpike, New Hyde Park, New York 11040. At the Special Meeting, you
will be asked to consider and vote upon AFC's issuance of shares of AFC common
stock (the "Merger Shares") in connection with the Agreement and Plan of Merger
entered into by AFC, Astoria Federal Savings and Loan Association ("Astoria
Federal") and The Greater New York Savings Bank ("GNYSB") on March 29, 1997, as
amended (the "Merger Agreement"), and an amendment to AFC's Certificate of
Incorporation to change the par value of AFC's authorized preferred stock from
$0.01 to $1.00 per share (the "Certificate Amendment").
 
     The Merger Agreement provides for the merger of GNYSB with and into Astoria
Federal with Astoria Federal being the surviving corporation (the "Merger"). It
also provides that the aggregate consideration payable to stockholders of GNYSB
Common Stock in the Merger will consist of 0.5 of a share of AFC Common Stock
per share of GNYSB Common Stock for 75% of the shares of GNYSB Common Stock and
$19.00 in cash per share of GNYSB Common Stock for the remaining 25% of the
shares of GNYSB Common Stock. Each share of GNYSB Common Stock will be converted
in the Merger into the right to receive: (i) 0.5 of a share of AFC Common Stock,
(ii) $19.00 in cash or (iii) a combination of cash and a fraction of a share of
AFC Common Stock (collectively, the "Merger Consideration"). The Merger
Consideration may be increased by AFC in the event GNYSB exercises its rights
under the Merger Agreement to deliver to AFC a notice to terminate the Merger
Agreement due to the price of the AFC Common Stock declining below certain
levels established by formulas set forth in the Merger Agreement. The actual
consideration ultimately received by a stockholder for shares of GNYSB Common
Stock will depend upon certain election, allocation and proration procedures and
the election of other stockholders as described in the accompanying materials.
GNYSB expects that the shares of GNYSB Series A ESOP Convertible Preferred Stock
will be converted into shares of GNYSB Common Stock prior to the consummation of
the Merger. Holders of shares of GNYSB 12% Noncumulative Perpetual Preferred
Stock, Series B will receive an equal amount of shares of a newly-created series
of preferred stock of AFC with substantially identical and no less favorable
terms.
 
     The Merger Agreement has been unanimously approved by the Boards of
Directors of AFC, Astoria Federal and GNYSB. Your Board of Directors has
determined that the Merger is in the best interests of AFC and its stockholders
and unanimously recommends that you vote FOR approval of the issuance of the
Merger Shares and the Certificate Amendment.
 
     Approval by the AFC stockholders of the issuance of the Merger Shares and
the Certificate Amendment is a condition to the consummation of the Merger.
Consummation of the Merger is also subject to certain other conditions,
including the approval of the Merger Agreement by GNYSB's stockholders entitled
to vote on the Merger Agreement and the approval of the Merger by various
regulatory agencies. The stockholders of GNYSB will consider and vote upon a
proposal to approve the Merger Agreement at a special meeting to be held on
August 1, 1997.
 
     The enclosed Notice of Special Meeting of Stockholders and Joint Proxy
Statement-Prospectus describe the Merger and provide information concerning the
Special Meeting. Please read these materials carefully.
 
     The affirmative vote of a majority of the total votes cast at the AFC
Meeting and entitled to vote thereon is required for approval of the issuance of
the Merger Shares. In addition, the affirmative vote of a majority of shares of
AFC Common Stock outstanding is required for approval of the Certificate
Amendment, which approval is a condition to the completion of the Merger.
Accordingly, a failure to return a properly executed proxy card or to vote in
person will have the same effect as a vote against the Certificate Amendment.
Your vote is very important regardless of the number of shares you own. Whether
or not you plan to attend the Special Meeting, I urge you to sign, date and
return the enclosed blue proxy card as soon as possible to ensure that your
shares will be represented at the Special Meeting.
 
     The Merger is an important step for AFC and its stockholders. On behalf of
the Board of Directors, I urge you to vote FOR both proposals.
 
     If you have any questions, please call (516) 327-3000.
 
                                        Sincerely,

June 24, 1997
 
Dear Stock Holder:
 
     It is with great pleasure that I extend to you a cordial invitation to
attend a Special Meeting of Stockholders of The Greater New York Savings Bank
("GNYSB"). The Special Meeting will be held on August 1, 1997 at 9:30 a.m.,
Eastern Time at The Grand Prospect Hall, 263 Prospect Avenue, Brooklyn, New York
11215. As you may be aware, on March 29, 1997, GNYSB, Astoria Financial
Corporation ("AFC") and Astoria Federal Savings and Loan Association ("Astoria
Federal") entered into an Agreement and Plan of Merger (the "Merger Agreement")
which provides for the merger of GNYSB into Astoria Federal with Astoria Federal
being the surviving corporation (the "Merger"). At the Special Meeting, you will
be asked to consider and vote upon a proposal to approve the Merger Agreement.
 
     The Merger Agreement provides that the aggregate consideration payable to
holders of GNYSB Common Stock in the Merger will consist of 0.5 of a share of
AFC Common Stock per share of GNYSB Common Stock for 75% of the shares of GNYSB
Common Stock and $19.00 in cash per share of GNYSB Common Stock for the
remaining 25% of the shares of GNYSB Common Stock. Each share of GNYSB Common
Stock will be converted in the Merger into the right to receive: (i) 0.5 of a
share of AFC Common Stock, (ii) $19.00 in cash or (iii) a combination of cash
and a fraction of a share of AFC Common Stock. The actual consideration
ultimately received by a stockholder for shares of GNYSB Common Stock will
depend upon certain election, allocation and proration procedures and the
election of other stockholders as described in the accompanying materials.
Because the Merger provides that the aggregate consideration payable to holders
of GNYSB Common Stock in the Merger will be fixed such that it consists of 0.5
of a share of AFC Common Stock per share of GNYSB Common Stock for 75% of the
shares of GNYSB Common Stock and $19.00 in cash per share of GNYSB Common Stock
for the remaining 25% of the shares of GNYSB Common Stock, no guarantee can be
given that the election of any given stockholder will be honored.
 
     GNYSB expects that the shares of GNYSB Series A ESOP Convertible Preferred
Stock (the "GNYSB Series A Preferred Stock") held in The Greater New York
Savings Bank Employee Stock Ownership Plan will be converted into shares of
GNYSB Common Stock prior to the consummation of the Merger and exchanged as
described above. Holders of shares of GNYSB 12% Noncumulative Perpetual
Preferred Stock, Series B will receive an equal amount of shares of a
newly-created series of preferred stock of AFC with substantially identical and
no less favorable terms.
 
     The Merger Agreement has been unanimously approved by the Boards of
Directors of GNYSB, AFC and Astoria Federal. Your Board has determined that the
Merger is in the best interests of GNYSB and its stockholders and unanimously
recommends that you vote FOR approval of the Merger Agreement. The investment
banking firm of Sandler O'Neill & Partners, L.P. has advised your Board of
Directors that, in its opinion, as of June 24, 1997, the consideration to be
received by the holders of GNYSB Common Stock and the GNYSB Series B Preferred
Stock is fair from a financial point of view to the holders of such shares.
 
     Consummation of the Merger is subject to certain conditions, including the
approval of the Merger Agreement by the requisite vote of GNYSB stockholders,
the approval of the issuance of the shares to be issued in the Merger and an
amendment to AFC's Certificate of Incorporation by the requisite vote of AFC
stockholders, and the approval of the Merger by various regulatory agencies. The
stockholders of AFC will
<PAGE>   5
 
consider and vote upon a proposal to approve the transactions contemplated by
the Merger Agreement at a special meeting to be held at 9:30 a.m., Eastern Time,
on August 1, 1997.
 
     The enclosed Notice of Special Meeting of Stockholders and Joint Proxy
Statement-Prospectus describe the Merger and provide information regarding the
Special Meeting. Please read these materials carefully.
 
     Your vote is very important regardless of the number of shares you own. The
affirmative vote of two-thirds of the aggregate outstanding shares of GNYSB
Common Stock and GNYSB Series A Preferred Stock entitled to vote at the Special
Meeting, voting as a single class, is required to approve the Merger Agreement.
A failure to return a properly executed proxy card or to vote in person will
have the same effect as a vote against the Merger Agreement. Therefore, I urge
you to execute, date and return the enclosed white proxy card in the enclosed
postage paid envelope as soon as possible to assure that your shares will be
voted at the Special Meeting. YOU SHOULD NOT SEND IN CERTIFICATES FOR YOUR
SHARES OF GNYSB COMMON STOCK OR GNYSB SERIES A PREFERRED STOCK AT THIS TIME.
 
     On behalf of the Board of Directors, we thank you for your support and urge
you to vote FOR approval of the Merger Agreement.
 
     If you have any questions, please call us at (212) 613-4075. I look forward
to seeing you on August 1, 1997.
 
Sincerely,
 
/s/ Gerard C. Keegan

                          TO BE HELD ON AUGUST 1, 1997
 
     A Special Meeting of Stockholders (the "Special Meeting") of The Greater
New York Savings Bank ("GNYSB") will be held on August 1, 1997 at 9:30 a.m.,
Eastern Time, at The Grand Prospect Hall, 263 Prospect Avenue, Brooklyn, New
York 11215, for the following purposes:
 
          1. To consider and vote upon a proposal to approve the Agreement and
     Plan of Merger, dated as of the 29th day of March, 1997, as amended, by and
     among Astoria Financial Corporation ("AFC"), a Delaware corporation,
     Astoria Federal Savings and Loan Association ("Astoria Federal"), a
     federally chartered savings and loan association, and GNYSB and the related
     Plan of Bank Merger to be entered into between GNYSB and Astoria Federal
     (together, the "Merger Agreement"). The Merger Agreement provides for the
     merger of GNYSB with and into Astoria Federal (the "Merger"), pursuant to
     which each share of common stock of GNYSB, par value $1.00 per share
     ("GNYSB Common Stock"), will be converted into the right to receive (i)
     0.50 of a share of the common stock of AFC, par value $0.01 per share,
     together with the related preferred share purchase right issued pursuant to
     the Rights Agreement between AFC and ChaseMellon Shareholder Services,
     L.L.C. dated as of July 17, 1996 (together, the "AFC Common Stock"), (ii)
     $19.00 in cash or (iii) a combination of cash and a fraction of a share of
     AFC Common Stock subject to certain election, allocation and proration
     procedures (collectively, the "Merger Consideration"). The Merger
     Consideration may be increased by AFC in the event GNYSB exercises its
     rights under the Merger Agreement to deliver to AFC a notice to terminate
     the Merger Agreement due to the price of the AFC Common Stock declining
     below certain levels established by formulas set forth in the Merger
     Agreement. The Merger Agreement also provides that the aggregate
     consideration payable to holders of GNYSB Common Stock in the Merger will
     consist of 0.5 of a share of AFC Common Stock per share of GNYSB Common
     Stock for 75% of the shares of GNYSB Common Stock and $19.00 in cash per
     share of GNYSB Common Stock for the remaining 25% of the shares of GNYSB
     Common Stock. GNYSB expects that the shares of GNYSB Series A ESOP

     United States Trust Company of New York, as trustee of the trust created
     pursuant to The Greater New York Savings Bank Employee Stock Ownership Plan
     Trust Agreement, dated February 13, 1989, will be converted into shares of
     GNYSB Common Stock prior to the consummation of the Merger and otherwise
     exchanged as described above. In addition, each share of 12% Noncumulative
     Perpetual Preferred Stock, Series B, par value $1.00 per share, of GNYSB
     will be exchanged for a share of a newly-created series of preferred stock
     of AFC having substantially identical and no less favorable terms. A copy
     of the Agreement and Plan of Merger, as amended, is included as Appendix A
     to the accompanying Joint Proxy Statement-Prospectus and a copy of the Plan
     of Bank Merger is included as Appendix C; and
 
          2. To consider and vote upon a proposal to authorize the Board of
     Directors of GNYSB, in its discretion, to vote upon such other business as
     may properly come before the Special Meeting and any adjournment or
     postponement thereof, including, without limitation, a motion to adjourn
     the Special Meeting to another time or place for the purpose of soliciting
     additional proxies in order to approve and adopt the Merger Agreement or
     otherwise.

Merger Agreement who does not vote in favor thereof has the right to receive
payment of the fair value of such holder's shares upon compliance with the
provisions of Section 6022 of the New York Banking Law, the full text of which
is included as Appendix F to the Joint Proxy Statement-Prospectus attached to
this Notice of Special Meeting. In the event shares of GNYSB Series A Preferred
Stock are converted into shares of GNYSB Common Stock, holders of the GNYSB
Series A Preferred Stock who dissent from the Merger will have dissenters'
rights with respect to the shares of GNYSB Common Stock into which the GNYSB
Series A Preferred Stock is converted. For a summary of the dissenters' rights
of GNYSB's stockholders, see "THE MERGER -- Dissenters' Rights" in the Joint

                       THE GREATER NEW YORK SAVINGS BANK
 
                             JOINT PROXY STATEMENT
                         ------------------------------
 
                         ASTORIA FINANCIAL CORPORATION
 
                                   PROSPECTUS
        (UP TO 5,666,517 SHARES OF COMMON STOCK, SUBJECT TO ADJUSTMENT)
                         ------------------------------
 
     This Joint Proxy Statement-Prospectus is being furnished to the holders of
common stock, par value $1.00 per share ("GNYSB Common Stock"), of The Greater
New York Savings Bank ("GNYSB") and to holders of the GNYSB Series A ESOP
Convertible Preferred Stock, par value $1.00 per share ("GNYSB Series A
Preferred Stock"), each in connection with the solicitation of proxies by the
GNYSB Board of Directors (the "GNYSB Board") for use at a special meeting of
GNYSB's stockholders to be held at 9:30 a.m., Eastern Time, on August 1, 1997,
at The Grand Prospect Hall, 263 Prospect Avenue, Brooklyn, New York 11215, and
at any adjournment or postponement thereof (the "GNYSB Meeting").
 
     At the GNYSB Meeting, holders of GNYSB Common Stock and GNYSB Series A
Preferred Stock, will consider and vote, together as a single class, upon a
proposal to approve the Agreement and Plan of Merger, dated as of the 29th day
of March, 1997, as amended, by and among Astoria Financial Corporation ("AFC"),
Astoria Federal Savings and Loan Association ("Astoria Federal"), and GNYSB, and
the related Plan of Bank Merger to be entered into between GNYSB and Astoria
Federal (together, the "Merger Agreement") pursuant to which GNYSB will merge
with and into Astoria Federal (the "Merger"), with Astoria Federal surviving the
Merger. Holders of GNYSB Common Stock or GNYSB Series A Preferred Stock who
deliver a written objection to the Merger to the Secretary of GNYSB before the
vote on the adoption of the Merger Agreement at the GNYSB Meeting and otherwise
comply with the additional requirements of Section 6022 of the New York Banking
Law will be entitled to dissenters' rights in connection with the Merger. In the
event shares of GNYSB Series A Preferred Stock are converted into shares of
GNYSB Common Stock, holders of the GNYSB Series A Preferred Stock who dissent
from the Merger will have dissenters' rights with respect to the shares of GNYSB
Common Stock into which the GNYSB Series A Preferred Stock is converted. See
"THE MERGER -- Dissenters' Rights." Holders of GNYSB Series B Preferred Stock
are not entitled to vote at the GNYSB Meeting.
 
     The Merger Agreement provides that the aggregate consideration (the "Merger
Consideration") payable to holders of GNYSB Common Stock will consist of 0.5 of
a share of common stock of AFC, par value $0.01 per share ("AFC Common Stock")
together with the related preferred share purchase right ("AFC Right") issued
pursuant to the Rights Agreement between AFC and ChaseMellon Shareholder
Services, L.L.C. dated as of July 17, 1996 (the "AFC Rights Agreement") per
share of GNYSB Common Stock for 75% of the shares of GNYSB Common Stock (the
"Stock Consideration") and $19.00 in cash per share of GNYSB Common Stock for
the remaining 25% of the shares of GNYSB Common Stock (the "Cash
Consideration"). Each share of GNYSB Common Stock will be converted in the
Merger into the right to receive: (i) 0.5 of a share of AFC Common Stock, (ii)
$19.00 in cash or (iii) a combination of cash and a fraction of a share of AFC
Common Stock determined as provided below. The actual consideration ultimately
received by a stockholder for shares of GNYSB Common Stock will depend upon
certain election, allocation and proration procedures and the election of other
stockholders as described herein. Because the Merger provides that the aggregate
consideration payable to holders of GNYSB Common Stock in the Merger will be
fixed such that it consists of 0.5 of a share of AFC Common Stock per share of
GNYSB Common Stock for 75% of the shares of GNYSB Common Stock and $19.00 in
cash per share of GNYSB Common Stock for the remaining 25% of the shares of
GNYSB Common Stock, no guarantee can be given that the election of any given
stockholder of GNYSB will be honored.
 
     GNYSB expects that the shares of GNYSB Series A Preferred Stock, held by
United States Trust Company of New York (the "GNYSB ESOP Trustee"), as trustee
of the trust created pursuant to The Greater New York Savings Bank Employee
Stock Ownership Plan Trust Agreement, dated February 13, 1989 (the "GNYSB
ESOP"), will be converted into shares of GNYSB Common Stock prior to the
consummation of the Merger and otherwise exchanged as described above. Holders
of GNYSB Common Stock who own less than 100 shares will not be entitled to elect
to receive the Stock Consideration but must elect the Cash
 
                                        1
<PAGE>   9
 
Consideration or be treated as having made no election under the election and
allocation procedures described herein. The Merger Consideration may be
increased by AFC in the event GNYSB exercises its rights under the Merger
Agreement to deliver to AFC a notice to terminate the Merger Agreement due to
the price of the AFC Common Stock declining below certain levels established by
formulas set forth in the Merger Agreement. See "THE MERGER -- Price Based
Termination." Holders of shares of GNYSB 12% Noncumulative Perpetual Preferred
Stock, Series B, par value $1.00 per share (the "GNYSB Series B Preferred
Stock"), will receive an equal amount of shares of a newly-created series of
preferred stock of AFC with substantially identical and no less favorable terms
("AFC Series B Preferred Stock").
 
     This Joint Proxy Statement-Prospectus is also being furnished to the
holders of AFC Common Stock in connection with the solicitation of proxies by
the AFC Board of Directors (the "AFC Board") for use at a special meeting of
AFC's stockholders to be held at 9:30 a.m., Eastern Time on August 1, 1997, at
the New Hyde Park Inn, 214 Jericho Turnpike, New Hyde Park, New York 11040, and
at any adjournment or postponement thereof (the "AFC Meeting" and, together with
the GNYSB Meeting, the "Meetings"). At the AFC Meeting, AFC stockholders will
consider and vote upon a proposal to approve the issuance of shares of AFC
Common Stock to be exchanged for shares of GNYSB Common Stock pursuant to the
Merger Agreement and an amendment to AFC's Certificate of Incorporation to
change the par value of AFC's authorized preferred stock from $0.01 to $1.00 per
share ("Certificate Amendment").
 
     Each of the stockholders of AFC and GNYSB entitled to vote at the Meetings
will also consider and vote upon a proposal to authorize their respective Board
of Directors to vote upon such other business as may properly come before the
AFC Meeting and GNYSB Meeting, respectively, including and without limitation a
motion to adjourn the AFC Meeting, or the GNYSB Meeting, as the case may be, to
another time or place for the purpose of soliciting additional proxies (the
"Additional Proposal"). See "ADDITIONAL PROPOSAL."
 
     This Joint Proxy Statement-Prospectus also constitutes a prospectus of AFC
with respect to up to 5,666,517 shares of AFC Common Stock to be issued in
exchange for shares of GNYSB Common Stock upon consummation of the Merger
pursuant to the Merger Agreement, subject to adjustment in the event the Merger
Consideration is increased as described in "THE MERGER -- Price-Based
Termination" (the "Merger Shares"). As a result of the Merger, holders of GNYSB
Common Stock as of completion of the Merger will own approximately 21% of the
outstanding shares of AFC Common Stock. (This percentage is based on outstanding
shares at March 31, 1997 and assumes conversion of the GNYSB Series A Preferred
Stock into GNYSB Common Stock.)
 
     For a description of the Merger Agreement, which is included in its
entirety as Appendix A to this Joint Proxy Statement-Prospectus, see "THE
MERGER."
 
     AFC Common Stock and GNYSB Common Stock are currently, and the Merger
Shares will be, traded in the over-the-counter market and included for quotation
on the National Market System of the Nasdaq Stock Market (the "Nasdaq National
Market"). The last reported sale prices per share of AFC Common Stock and GNYSB
Common Stock as reported on the Nasdaq National Market on March 27, 1997, the
last business day preceding public announcement of the signing of the Merger
Agreement, were $37 7/8 and $17 7/8, respectively, and on June 20, 1997 were
$45 5/8 and $21 1/4, respectively.
 
     All of the shares of the GNYSB Series A Preferred Stock are held by the
GNYSB ESOP Trustee.
 
     This Joint Proxy Statement-Prospectus and the accompanying proxy card are
first being mailed to stockholders of AFC and GNYSB on or about June 25, 1997.

JOINT PROXY STATEMENT-PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.

     The following summary is not intended to be a complete description of all
material facts regarding AFC, GNYSB and the matters to be considered at the
Meetings and is qualified in all respects by the information appearing elsewhere

     See INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE," "THE MERGER --
Parties to the Merger," "SELECTED CONSOLIDATED FINANCIAL AND OTHER DATA,"
"CERTAIN REGULATORY CONSIDERATIONS" and "UNAUDITED PRO FORMA COMBINED CONDENSED
CONSOLIDATED FINANCIAL INFORMATION."
 
THE MEETINGS
 
     GNYSB.  The GNYSB Meeting will be held at 9:30 a.m., Eastern Time, on
August 1, 1997 at The Grand Prospect Hall, 263 Prospect Avenue, Brooklyn, New
York 11215. The purpose of the GNYSB Meeting is to consider and vote upon a
proposal to approve the Merger Agreement and a proposal to authorize the GNYSB
Board, in its discretion, to vote upon such other business as may properly come
before the GNYSB Meeting, including, without limitation, a motion to adjourn the
GNYSB Meeting to another time or place for the purpose of soliciting additional
proxies in order to approve and adopt the Merger Agreement or otherwise.
 
                                        9

     Only holders of record of GNYSB Common Stock and GNYSB Series A Preferred
Stock at the close of business on June 19, 1997 (the "GNYSB Record Date") will
be entitled to vote at the GNYSB Meeting with each entitled to one vote per
share. The affirmative vote of two-thirds of the aggregate outstanding shares on
the GNYSB Record Date of GNYSB Common Stock and GNYSB Series A Preferred Stock
entitled to vote at the GNYSB Meeting, voting as a single class, is required to
approve the Merger Agreement. In addition, assuming the existence of a quorum,
the affirmative vote of a majority of the votes present in person or by proxy
and entitled to vote at the GNYSB Meeting is required to approve the Additional
Proposal (as defined herein). As of the GNYSB Record Date, there were 13,714,485
shares of GNYSB Common Stock outstanding and entitled to be voted at the GNYSB
Meeting and 1,477,802 shares of GNYSB Series A Preferred Stock outstanding and
entitled to be voted at the GNYSB Meeting. Holders of GNYSB Series B Preferred
Stock are not entitled to vote at the GNYSB Meeting.
 
     As of April 30, 1997, GNYSB's directors and executive officers (and their
affiliates) (22 persons) beneficially owned and had the power to vote 271,109
shares of GNYSB Common Stock, beneficially owned, but did not have the right to
vote approximately 84,133 shares of GNYSB Common Stock held in the GNYSB
Incentive Savings Plan and had a beneficial interest in, and the right to direct
the voting of, approximately 143,195 shares of GNYSB Common Stock and GNYSB
Series A Preferred Stock held in the GNYSB ESOP accounts. Such shares of GNYSB
Common Stock and GNYSB Series A Preferred Stock which GNYSB's directors and
executive officers (and their affiliates) have the right to vote or direct the
voting thereof, represent approximately 2.73%, as of April 30, 1997, of the
outstanding GNYSB Common Stock and GNYSB Series A Preferred Stock which may be
voted at the GNYSB Meeting. Such persons have indicated their intention to vote,
or direct the voting of, all such shares, in favor of the Merger Agreement and
for the Additional Proposal (as defined herein). See "BENEFICIAL OWNERSHIP OF
GNYSB COMMON STOCK." The Trustee of the GNYSB ESOP is obligated to vote
unallocated shares and shares for which no direction has been received in the
same proportion as shares for which such voting directions have been received
from participants, so long as such vote is in accordance with the provisions of
the Employee Retirement Income Security Act of 1974, as amended ("ERISA"). As of
April 30, 1997, AFC, its subsidiaries, and the directors and executive officers
of AFC, beneficially owned 240,000 shares or approximately 1.75% of GNYSB Common
Stock. Such persons have indicated their intention to vote, or direct the voting
of, all such shares, in favor of the Merger Agreement and for the Additional
Proposal. See "THE MEETINGS -- GNYSB Meeting."
 
     AFC.  The AFC Meeting will be held at 9:30 a.m., Eastern Time, on August 1,
1997 at the New Hyde Park Inn, 214 Jericho Turnpike, New Hyde Park, New York
11040. The purpose of the AFC Meeting is to consider and vote upon a proposal to
approve the issuance of the Merger Shares, a proposal to approve the Certificate
Amendment in connection with the Merger, and a proposal to authorize the AFC
Board, in its discretion, to vote upon such other business as may properly come
before the AFC Meeting and any adjournment thereof, including, without
limitation, a motion to adjourn the AFC Meeting to another time or place for the
purpose of soliciting additional proxies in order to approve the issuance of the
Merger Shares, the Certificate Amendment, or otherwise. The proposals to
authorize the AFC Board or the GNYSB Board, as the case may be, to vote upon
such other business as may properly come before the AFC Meeting or the GNYSB
Meeting, as the case may be, is hereinafter referred to as the "Additional
Proposal." See the "ADDITIONAL PROPOSAL."
 
     Only holders of record of AFC Common Stock at the close of business on June
23, 1997 (the "AFC Record Date") will be entitled to vote at the AFC Meeting.
The issuance of the Merger Shares and the Additional Proposal requires the
affirmative vote of the holders of a majority of the shares of AFC Common Stock
represented in person or by proxy at the AFC Meeting. The affirmative vote of a
majority of shares of AFC Common Stock outstanding is required for approval of
the Certificate Amendment. As of the AFC Record Date, there were 20,972,257
shares of AFC Common Stock outstanding and entitled to be voted at the AFC
Meeting.
 
     The directors and executive officers of AFC and their affiliates (13
persons) beneficially owned, as of April 30, 1997, 2,081,461 shares, or
approximately 9.32% of the outstanding shares, of AFC Common Stock and all such
persons have indicated a present intent to vote their shares in favor of
approval of the issuance of
 
                                       10
<PAGE>   18
 
the Merger Shares, the Certificate Amendment and the Additional Proposal. See
"BENEFICIAL OWNERSHIP OF AFC COMMON STOCK." As of April 30, 1997, GNYSB, its
subsidiaries and the directors and executive officers of GNYSB beneficially
owned 1,304 shares of AFC Common Stock. See "THE MEETINGS -- AFC Meeting."
 
REASONS FOR THE MERGER; RECOMMENDATIONS OF BOARDS OF DIRECTORS
 
     GNYSB.  THE GNYSB BOARD HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND
HAS DETERMINED THAT THE MERGER IS IN THE BEST INTERESTS OF GNYSB AND ITS
STOCKHOLDERS. THE GNYSB BOARD, THEREFORE, UNANIMOUSLY RECOMMENDS THAT GNYSB'S
STOCKHOLDERS VOTE FOR APPROVAL OF THE MERGER AGREEMENT AND THE ADDITIONAL
PROPOSAL. The GNYSB Board believes that the Merger will provide significant
value to all GNYSB stockholders and also enable them to participate in the
opportunities for growth that the GNYSB Board believes the Merger makes
possible. See "THE MEETINGS -- GNYSB Meeting -- Recommendation of the Board of
Directors" and "THE MERGER -- Background of and Reasons for the Merger --
GNYSB's Reasons for the Merger."
 
     AFC.  THE AFC BOARD HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND HAS
DETERMINED THAT THE MERGER, THE ISSUANCE OF THE MERGER SHARES AND THE
CERTIFICATE AMENDMENT PURSUANT THERETO ARE IN THE BEST INTERESTS OF AFC AND ITS
STOCKHOLDERS. THE AFC BOARD, THEREFORE, UNANIMOUSLY RECOMMENDS THAT AFC'S
STOCKHOLDERS VOTE FOR APPROVAL OF THE ISSUANCE OF THE MERGER SHARES, THE
CERTIFICATE AMENDMENT AND THE ADDITIONAL PROPOSAL. The AFC Board believes the
Merger will result in the addition of a well-suited and positioned banking
institution to AFC's existing organization. See "THE MEETINGS -- AFC Meeting --
Recommendation of the Board of Directors" and "THE MERGER -- Background of and
Reasons for the Merger -- AFC's Reasons for the Merger."
 
EFFECTS OF THE MERGER
 
     Pursuant to the Merger Agreement, at the Effective Time (as defined below),
GNYSB will be merged with and into Astoria Federal, and GNYSB stockholders will
receive the consideration described in "THE MERGER -- Merger Consideration and
Election, Allocation and Proration Procedures" and "-- Effects of the Merger."
For information on how GNYSB stockholders will be able to exchange certificates
representing shares of GNYSB Common Stock for new certificates representing the
shares of AFC Common Stock to be issued to them and/or cash, see "THE
MERGER -- Procedures for Exchange of GNYSB Common Stock Certificates." Each
outstanding share of AFC Common Stock at the Effective Time shall remain
outstanding and unchanged as a result of the Merger.
 
EFFECTIVE TIME
 
     The Merger will become effective at the date and time set forth in the
articles of combination which will be filed with the Office of Thrift
Supervision (the "OTS") in accordance with applicable law (the "Effective
Time"). The articles of combination will be filed not later than the last
business day of the month in which the last of the waiting periods related to
regulatory approval has occurred and after satisfaction or waiver of certain
conditions to the Merger specified in the Merger Agreement and become effective
after the close of business on such date, unless another date is agreed to by
AFC and GNYSB. See "THE MERGER -- Effective Time."
 
MERGER CONSIDERATION AND ELECTION, ALLOCATION AND PRORATION PROCEDURES
 
     General.  The Merger Agreement provides that the aggregate consideration
payable to holders of GNYSB Common Stock in the Merger will consist of 0.5 of a
share of AFC Common Stock per share of GNYSB Common Stock for 75% of the shares
of GNYSB Common Stock and $19.00 in cash per share of GNYSB Common Stock for the
remaining 25% of the shares of GNYSB Common Stock. Each share of GNYSB Common
Stock will be converted in the Merger into the right to receive: (i) 0.5 of a
share of AFC Common Stock, (ii) $19.00 in cash or (iii) a combination of cash
and a fraction of a share of AFC Common Stock determined as provided below. The
actual consideration ultimately received by a stockholder for shares of GNYSB
Common Stock will depend upon the election, allocation and proration procedures
described below and the election of other stockholders. The Merger Consideration
may be increased by AFC in the event GNYSB exercises its rights under the Merger
Agreement to deliver to AFC a notice to terminate the Merger
 
                                       11

Agreement due to the price of the AFC Common Stock declining below certain
levels established by formulas set forth in the Merger Agreement. See "THE
MERGER -- Price Based Termination."
 
     Elections.  Within three days after the consummation of the Merger, each
record holder of GNYSB Common Stock will be sent materials asking such
stockholder to elect (an "Election") to receive for its shares of GNYSB Common
Stock:
 
        (i) 0.5 of a share of AFC Common Stock for each share of GNYSB Common
     Stock (a "Stock Election");
 
        (ii) $19.00 in cash without interest for each share of GNYSB Common
     Stock (a "Cash Election");
 
          (iii) a Stock Election with respect to some of such stockholder's
     shares of GNYSB Common Stock and a Cash Election with respect to the
     remaining shares of GNYSB Common Stock held by such holder; or
 
          (iv) whatever is left after the election of the other holders of GNYSB
     Common Stock and the application, to the extent necessary, of certain
     random selection procedures (a "No-Election").
 
     Notwithstanding the foregoing, in order to make a Stock Election, the
number of shares of GNYSB Common Stock a holder must elect to convert to AFC
Common Stock must equal or exceed 100 shares. Therefore, any holder of GNYSB
Common Stock who owns less than 100 shares must elect the Cash Election or be
treated as having made a No-Election. A failure to properly make an Election as
described below will be treated as a No-Election.
 
     NO GAIN OR LOSS WILL BE RECOGNIZED BY HOLDERS OF GNYSB COMMON STOCK AS A
RESULT OF THE MERGER, EXCEPT WHERE ANY CASH CONSIDERATION IS RECEIVED OR TO THE
EXTENT OF ANY CASH RECEIVED IN LIEU OF A FRACTIONAL SHARE INTEREST IN AFC COMMON
STOCK. SEE "THE MERGER -- MATERIAL FEDERAL INCOME TAX CONSEQUENCES."
 
     No Oversubscription.  In the event that the number of shares as to which a
Cash Election has been made does not exceed 25% of the shares of GNYSB Common
Stock outstanding at the Effective Time and the number of shares as to which a
Stock Election has been made does not exceed 75% of the shares of GNYSB Common
Stock outstanding at the Effective Time, then:
 
          (i) all shares as to which a Cash Election has been made shall be
     converted into the right to receive $19.00 in cash without interest per
     share of GNYSB Common Stock;
 
          (ii) all shares as to which a Stock Election has been made shall be
     converted into the right to receive 0.5 of a share of AFC Common Stock per
     share of GNYSB Common Stock; and
 
          (iii) shares as to which No-Election has been made shall be converted
     into either the right to receive 0.5 of a share of AFC Common Stock per
     share of GNYSB Common Stock or $19.00 per share of GNYSB Common Stock as
     determined by random selection so that 25% of the shares of GNYSB Common
     Stock are converted into the right to receive cash and 75% of the shares of
     GNYSB Common Stock are converted into the right to receive AFC Common
     Stock.
 
     The random selection process to be used by ChaseMellon Shareholder
Services, LLC (the "Exchange Agent") will consist of drawing by lot or such
other process as the Exchange Agent deems equitable and necessary to effect the
allocations described above.
 
     Oversubscription for Cash.  If the aggregate number of shares as to which a
Cash Election has been made exceeds 25% of the shares of GNYSB Common Stock
outstanding at the Effective Time, then:
 
          (i) each share as to which a Stock Election has been made and each
     share as to which No-Election has been made shall be converted into the
     right to receive 0.5 of a share of AFC Common Stock; and
 
          (ii) each share as to which a Cash Election has been made shall be
     converted into the right to receive a combination of cash and AFC Common
     Stock. The amount in cash will be equal to the product, rounded to the
     nearest $0.01, of (x) $19.00 and (y) a fraction (the "Cash Fraction"), the
     numerator of
 
                                       12
<PAGE>   20
 
     which shall be a number equal to 25% of the shares of GNYSB Common Stock
     outstanding at the Effective Time and the denominator of which shall be the
     total number of shares as to which a Cash Election has been made. The
     number of shares of AFC Common Stock will be equal to the product, rounded
     to four decimal places, of (x) 0.50 and (y) a number equal to one minus the
     Cash Fraction. For example, if the aggregate number of shares as to which a
     Cash Election has been made equals 50%, 75% or 100% of the shares of GNYSB
     Common Stock, the combination would consist of $9.50 in cash and 0.25 of a
     share of AFC Common Stock, $6.33 in cash and 0.3333 of a share of AFC
     Common Stock and $4.75 in cash and 0.375 of a share of AFC Common Stock,
     respectively.
 
     Oversubscription for AFC Common Stock.  If the aggregate number of shares
as to which a Stock Election has been made exceeds 75% of the shares of GNYSB
Common Stock outstanding at the Effective Time, then:
 
          (i) each share as to which a Cash Election has been made and each
     share as to which No-Election has been made shall be converted into the
     right to receive $19.00 in cash without interest; and
 
          (ii) each share as to which a Stock Election has been made shall be
     converted into the right to receive a combination of cash and AFC Common
     Stock. The number of shares of AFC Common Stock will be equal to the
     product, rounded to four decimal places, of (x) 0.50 and (y) a fraction
     (the "Stock Fraction"), the numerator of which shall be a number equal to
     75% of the shares of GNYSB Common Stock outstanding at the Effective Time
     and the denominator of which shall be the total number of shares as to
     which a Stock Election has been made. The amount of cash will be equal to
     the product, rounded to the nearest $0.01, of (x) $19.00 and (y) a number
     equal to one minus the Stock Fraction. For example, if the aggregate number
     of shares as to which a Stock Election has been made equals 90% or 100% of
     the shares of GNYSB Common Stock, the combination would consist of 0.4167
     of a share of AFC Common Stock and $3.17 in cash and 0.375 of a share of
     AFC Common Stock and $4.75 in cash, respectively.
 
     No Guarantee of Chosen Consideration or Equivalent Value.  Because the
Merger provides that the aggregate consideration payable to holders of GNYSB
Common Stock in the Merger will be fixed such that it consists of 0.5 of a share
of AFC Common Stock per share of GNYSB Common Stock for 75% of the shares of
GNYSB Common Stock and $19.00 in cash per share of GNYSB Common Stock for the
remaining 25% of the shares of GNYSB Common Stock, no guarantee can be given
that the Election of any given stockholder of GNYSB will be honored. Rather, the
election by each stockholder will be subject to the election, allocation and
proration procedures described herein. Thus stockholders may not receive their
requested form of consideration or combination thereof. Because the market price
of AFC Common Stock may fluctuate and it could be greater than or less than
$38.00 per share (the price at which the market value of 0.5 of a share of AFC
Common Stock would equal the cash consideration of $19.00 per share), the market
value of 0.5 of a share of AFC Common Stock received per share could be less
than or greater than the cash price per share of $19.00.
 
     Election Procedures.  All Elections will be required to be made on a Letter
of Transmittal and Election Form. To make an effective Election with respect to
shares of GNYSB Common Stock, the holder thereof must, in accordance with the
Letter of Transmittal and Election Form, (i) complete properly and return the
Letter of Transmittal and Election Form to the Exchange Agent, (ii) either (a)
deliver therewith his or her certificates representing shares of GNYSB Common
Stock (the "GNYSB Stock Certificates") with respect to such shares (or an
appropriate guarantee of delivery thereof), or (b) complete the procedure for
delivery by book-entry transfer of such shares on a timely basis, and (iii)
deliver therewith any other required documents, prior to 5:00 p.m. on the 10th
business day following mailing of the Letter of Transmittal and Election Form
(the "Election Deadline").
 
     GNYSB STOCK CERTIFICATES SHOULD NOT BE RETURNED WITH THE ENCLOSED PROXY AND
SHOULD NOT BE FORWARDED TO THE EXCHANGE AGENT UNTIL A GNYSB STOCKHOLDER HAS
RECEIVED THE LETTER OF TRANSMITTAL AND ELECTION FORM.
 
     A holder of shares of GNYSB Common Stock having a preference as to the form
of consideration to be received for his or her shares of GNYSB Common Stock
should make an Election because shares as to which an Election has been made
will be given priority in allocating such consideration over shares as to which
an
 
                                       13
<PAGE>   21
 
Election is not received. Neither GNYSB nor the GNYSB Board makes any
recommendation as to whether stockholders should elect to receive the Cash
Consideration or the Stock Consideration in the Merger. Each holder of GNYSB
Common Stock must make his or her own decision with respect to such election.
     GNYSB Series A Preferred Stock.  All of the shares of the GNYSB Series A
Preferred Stock are held by the GNYSB ESOP Trustee. The shares held in the GNYSB
ESOP and allocated to participants' accounts are voted by the beneficial owners
of such shares based on directions received from such beneficial owners by the
trustee of the GNYSB ESOP. Unallocated shares and any allocated shares with
respect to which no voting instructions have been received will be voted by the
trustee of the GNYSB ESOP in the same manner and proportion as the allocated
shares with respect to which voting instructions have been received, as long as
such vote is in accordance with the provisions of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA").
     1,477,802 shares of GNYSB Series A Preferred Stock were outstanding on the
Record Date, but may be redeemed or converted into shares of GNYSB Common Stock
at any time after the date of this Joint Proxy Statement-Prospectus and prior to
the anticipated closing date of the Merger. The Merger Agreement requires that
if certain conditions are satisfied GNYSB is obligated to redeem all of the
shares of the GNYSB Series A Preferred Stock prior to the consummation of the
Merger. These conditions include (i) the approval of the Merger Agreement and
related transactions by the holders of GNYSB and AFC stock entitled to vote
thereon, (ii) the receipt of all required regulatory approvals, (iii) the waiver
by AFC of all conditions to its obligations to consummate the Merger and (iv) a
market price of AFC Common Stock of at least $34.125. The redemption price in
effect after July 1, 1997 for the GNYSB Series A Preferred Stock is $13.20 plus
accrued dividends to the date of redemption. The effectiveness of such
redemption is a condition to the consummation of the Merger. GNYSB may, of its
own accord, provide a notice of redemption to the GNYSB ESOP Trustee at any
time. However, it has not yet done so because it was determined that it was in
the best interest of both GNYSB and the GNYSB ESOP and its participants to
receive a dividend for the full semi-annual period ending June 30, 1997. AFC has
requested that GNYSB exercise its right to call the GNYSB Series A Preferred
Stock for redemption prior to the time frames set forth in the Merger Agreement,
and GNYSB has advised AFC that it will consider exercising such right to cause a
redemption to occur shortly after the payment of such dividend. However, no
assurance can be given that GNYSB will exercise such right within such time
frame. As long as the market price of the GNYSB Common Stock exceeds
approximately $14.00, GNYSB expects that the GNYSB ESOP Trustee will, in lieu of
allowing such shares to be redeemed for cash, convert such shares into shares of
GNYSB Common Stock with a conversion ratio of .9448 of a share of GNYSB Common
Stock for each share of GNYSB Series A Preferred Stock. Notwithstanding the
foregoing, GNYSB intends to seek the GNYSB ESOP Trustee's agreement to convert
the GNYSB Series A Preferred Stock prior to the time GNYSB is obligated to
redeem such shares. Shares of GNYSB Common Stock held by the GNYSB ESOP at the
Effective Time will be subject to the election, allocation and proration
procedures in the same manner as all other shares of GNYSB Common Stock. AFC
intends to enforce its rights to require the issuance of a notice of redemption
to the GNYSB ESOP Trustee, which will require the GNYSB ESOP Trustee to choose
either to allow such redemption or exercise its right of conversion at the
conversion ratio of .9448 per share. However, if for any reason AFC does not do
so and GNYSB does not of its own accord exercise its right to call the GNYSB
Series A Preferred Stock for redemption, the GNYSB Series A Preferred Stock
outstanding at the Effective Time of the Merger, under the Certificate of
Designations, would be deemed immediately prior to the Effective Time to have
been converted into shares of GNYSB Common Stock at a prescribed conversion
ratio.
     GNYSB Series B Preferred Stock.  Upon consummation of the Merger, the
outstanding shares of GNYSB Series B Preferred Stock will be converted into AFC
Series B Preferred Stock, a newly-created series of preferred stock of AFC with
substantially identical and no less favorable terms.
     Miscellaneous.  If AFC effects a stock dividend, reclassification,
recapitalization, split-up, combination, exchange of shares or similar
transaction prior to the Effective Time, an appropriate adjustment to the
consideration will be made.
     No fractional shares of AFC Common Stock will be issued in connection with
the Merger and cash will be paid in lieu thereof.
 
                                       14
<PAGE>   22
 
     Upon consummation of the Merger, any shares of GNYSB Common Stock that are
owned by GNYSB as treasury stock or that are held directly or indirectly by AFC,
other than in a fiduciary capacity or in satisfaction of a debt previously
contracted, will be canceled and retired and no payment will be made with
respect thereto and such shares will not be considered for purposes of the
foregoing. In addition, shares of GNYSB Common Stock with respect to which
dissenters' rights have been asserted and not withdrawn will not be converted
into the right to receive cash or AFC Common Stock as provided in the Merger
Agreement and will be considered No-Election Shares for purposes of applying the
allocation and proration procedures described herein. For certain information
concerning the historical market prices of GNYSB Common Stock and AFC Common
Stock, see "COMPARATIVE STOCK PRICE AND DIVIDEND INFORMATION."
 
     Dissenting Stockholders.  Any shares as to which dissenters' or appraisal
rights have been asserted and not withdrawn ("Dissenters' Shares") shall not be
converted into the right to receive the Merger Consideration unless and until
the holder shall have failed to perfect, or shall have effectively withdrawn or
lost, his right to dissent. If any such holder shall have so failed to perfect
or shall have effectively withdrawn or lost such right, each share of such
holder's GNYSB Common Stock shall be deemed to be No-Election Shares and shall
be subject to the allocation and proration procedures described herein. See "THE
MERGER -- Dissenters' Rights."
 
OPINIONS OF FINANCIAL ADVISORS
 
     GNYSB.  Sandler O'Neill & Partners, L.P. ("Sandler O'Neill") has served as
financial advisor to GNYSB in connection with the Merger and has rendered an
opinion to the GNYSB Board that, as of the date of this Joint Proxy
Statement-Prospectus, the consideration to be received by the holders of shares
of GNYSB Common Stock (including any shares that are issued upon the conversion
of shares of GNYSB Series A Preferred Stock) and GNYSB Series B Preferred Stock
pursuant to the Merger Agreement is fair, from a financial point of view, to
such stockholders. For additional information, see "THE MERGER -- Opinions of
Financial Advisors -- GNYSB." The opinion of Sandler O'Neill is attached as
Appendix D to this Joint Proxy Statement-Prospectus. Stockholders are urged to
read such opinion in its entirety for a description of the procedures followed,
assumptions made, matters considered and qualifications of the review undertaken
by Sandler O'Neill in connection therewith.
 
     AFC.  Merrill Lynch & Co. ("Merrill Lynch") has served as financial advisor
to AFC in connection with the Merger and has rendered a written opinion to the
AFC Board that, as of the date of this Joint Proxy Statement-Prospectus, the
proposed Merger Consideration is fair to AFC from a financial point of view. The
opinion of Merrill Lynch is attached as Appendix E to this Joint Proxy
Statement-Prospectus. Stockholders are urged to read such opinion in its
entirety for a description of the procedures followed, assumptions made, matters
considered and qualifications on the review undertaken by Merrill Lynch in
connection therewith. See "THE MERGER -- Opinions of Financial Advisors -- AFC."
 
CONDITIONS; REGULATORY APPROVALS
 
     Consummation of the Merger is subject to various conditions, including
receipt of the stockholder approvals solicited hereby, receipt of the necessary
regulatory approvals, receipt of opinions of counsel regarding certain tax
aspects of the Merger, and satisfaction of other customary closing conditions.
 
     The regulatory approvals and consents necessary to consummate the Merger
include the approvals of the OTS and the Superintendent of Banks of the State of
New York ("Superintendent"). Applications were filed on June 5, 1997. Such
applications are currently under review. THERE CAN BE NO ASSURANCE THAT SUCH
REGULATORY APPROVALS WILL BE OBTAINED, AND, IF THE MERGER IS APPROVED, THERE CAN
BE NO ASSURANCE AS TO THE DATE OF ANY SUCH APPROVAL. THERE CAN ALSO BE NO
ASSURANCE THAT ANY SUCH APPROVALS WILL NOT CONTAIN A CONDITION OR REQUIREMENT
WHICH CAUSES SUCH APPROVALS TO FAIL TO SATISFY THE CONDITIONS SET FORTH IN THE
MERGER AGREEMENT AND DESCRIBED UNDER "THE MERGER -- REGULATORY APPROVALS" AND
"CONDITIONS TO THE CONSUMMATION OF THE MERGER."

CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
     It is intended that the Merger will be treated as a reorganization within
the meaning of Section 368(a) of the Internal Revenue Code of 1986 (the "Code").
Consummation of the Merger is conditioned upon receipt by AFC of an opinion of
Thacher Proffitt & Wood and the receipt by GNYSB of an opinion of Sullivan &
Cromwell, each dated as of the Effective Date, substantially to such effect. In
general, it is expected that no gain or loss will be recognized by AFC, Astoria
Federal or GNYSB as a result of the Merger and, except where any Cash
Consideration is received or to the extent of any cash received in lieu of a
fractional share interest in GNYSB Common Stock, no gain or loss will be
recognized by holders of GNYSB Common Stock or GNYSB Series B Preferred Stock as
a result of the Merger. See "THE MERGER -- Material Federal Income Tax
Consequences."
ACCOUNTING TREATMENT
     AFC will treat the Merger as a purchase for accounting purposes. See "THE
MERGER -- Accounting Treatment."
NASDAQ LISTING
     Both the GNYSB Common Stock and the AFC Common Stock are currently included
for quotation on the Nasdaq National Market. It is a condition to consummation
of the Merger that the AFC Common Stock to be issued to the stockholders of
GNYSB pursuant to the Merger Agreement will be included for quotation on the
Nasdaq National Market. Similar to the GNYSB Series B Preferred Stock, the AFC
Series B Preferred Stock will not be listed on the Nasdaq National Market or on
any other exchange.
DISSENTERS' RIGHTS
     Holders of GNYSB Common Stock or GNYSB Series A Preferred Stock who deliver
a written objection to the Merger to the Secretary of GNYSB before the vote on
the adoption of the Merger Agreement at the GNYSB Meeting and otherwise comply
with the additional requirements of Section 6022 of the New York Banking Law
(the "NYBL") will be entitled to dissenters' rights in connection with the
Merger. A copy of Section 6022 of the NYBL is attached to this Joint Proxy
Statement-Prospectus as Appendix F. In the event shares of GNYSB Series A
Preferred Stock are converted into shares of GNYSB Common Stock, holders of the
GNYSB Series A Preferred Stock who dissent from the Merger will have dissenters'
rights with respect to the shares of GNYSB Common Stock into which the GNYSB
Series A Preferred Stock is converted. No stockholder of AFC is entitled to
dissenters' rights in connection with or as a result of the Merger. See "THE
MEETINGS -- GNYSB Meeting," "THE MERGER -- Dissenters' Rights," "-- Interests of
Certain Persons in the Merger," and "BENEFICIAL OWNERSHIP OF GNYSB COMMON
STOCK."
TERMINATION
     The Merger Agreement may be terminated, and the Merger abandoned, prior to
the Effective Time, either before or after its approval by the stockholders of
AFC or GNYSB under certain specified circumstances, including without limitation
a price-based termination provision. Under this provision, the Merger Agreement
may be terminated by GNYSB at any time during the five-day period commencing
with the date (the "Valuation Date") that is the latest of (i) the day of
expiration of the last waiting period with respect to any of the required
regulatory approvals, (ii) the day on which the last of the required regulatory
approvals is obtained and (iii) the day on which the last of the required
stockholder approvals have been received, such termination to be effective on
the 30th day following such date, but only if all of the following are true: (i)
the average closing price of AFC Common Stock over the 30 consecutive trading
days prior to the Valuation Date is less than $30.30 per share, (ii) the
quotient obtained by dividing such average closing price of AFC Common Stock on
the Valuation Date by $37.88 is less than the number obtained by subtracting
0.15 from the quotient obtained by dividing the weighted average common stock
price of a group of other financial institution holding companies over the 30
consecutive trading days prior to the Valuation Date by the weighted average
common stock price of such group on March 27, 1997 and (iii) AFC elects on a
timely basis not to
 
                                       16
<PAGE>   24
 
increase the Merger Consideration including the number of shares of AFC Common
Stock to be received by the holders of GNYSB Common Stock in the Merger. Prior
to making any decision to terminate (or allow the termination of) the Merger
Agreement, each of the GNYSB Board and the AFC Board would consult with its
respective financial and other advisors and would consider all financial and
other information it deemed relevant to its decision. Approval of the Merger
Agreement by the stockholders of GNYSB at the GNYSB Meeting will confer on the
GNYSB Board the power, consistent with its fiduciary duties, to elect to
consummate the Merger in the event the termination right is triggered whether or
not there is any increase in the Merger Consideration and without any further
action by, or resolicitation of, the stockholders of GNYSB. Approval of the
issuance of the Merger Shares by the stockholders of AFC of the AFC Meeting will
confer on the AFC Board the power, consistent with its fiduciary duties, to
elect to increase the Merger Consideration as described above and consummate the
Merger in the event the termination right is triggered without any further
actions by, or resolicitation of, the stockholders of AFC. See "THE
MERGER -- Price-Based Termination," "-- Termination" and "-- Termination Fees."
 
TERMINATION FEES
 
     In recognition of the efforts and expenses of, and other opportunities
foregone by AFC while structuring the Merger, the Merger Agreement provides that
GNYSB shall, in certain circumstances involving an attempt by a third party to
acquire GNYSB, pay to AFC a termination fee of $5 million in cash. In addition,
pursuant to the Stock Option Agreement (as defined herein), GNYSB granted AFC an
option to purchase up to 2,721,536 shares of GNYSB Common Stock at an exercise
price of $17.875 upon the occurrence of certain events. However, the maximum
aggregate profit AFC can receive under the Stock Option Agreement and the
termination fee arrangement is $10 million. See "THE MERGER -- Termination Fees"
and "CERTAIN RELATED TRANSACTIONS -- Stock Option Agreement."
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     Certain members of GNYSB's management and the GNYSB Board may be deemed to
have interests in the Merger in addition to their interests, if any, as
stockholders of GNYSB generally. These include interests relating to
indemnification, cash payments under employment agreements and change of control
agreements, cash payments under outstanding stock options or the roll-over of
stock options, service on an advisory board, employment agreements for executive
officers, certain benefits under the GNYSB Retirement Plan for Non-Employee
Directors and liability insurance coverage. The estimated maximum severance
benefits and excise tax indemnity payment amount under the Employment Agreements
(as defined herein) and the Change in Control Letter Agreements (as defined
herein) for the executive officers of GNYSB are as follows: Gerard C. Keegan,
$5,253,000 and $1,977,000; Michael J. Henchy, $1,352,000 and $535,000; Daniel J.
Harris, $846,000 and $408,000; Philip A. Cimino, $792,000 and $398,000; Philip
T. Spies, $618,000 and $274,000; and all executive officers as a group, which
consists of 13 persons, $12,956,000 and $5,622,000. The estimated maximum
aggregate amount that would be required to be paid pursuant to the Merger
Agreement in consideration for the cancellation of stock options for the
executive officers of GNYSB are as follows: Gerard C. Keegan, $3,665,311,
Michael J. Henchy, $1,133,146, Daniel J. Harris, $834,063, Philip A. Cimino,
$820,526, Philip T. Spies, $718,281; and all executive officers as a group,
which consists of 13 persons, $9,973,889. The estimated aggregate potential
benefits that could be payable in connection with the Merger to the directors of
GNYSB are described in more detail elsewhere herein. See "THE
MERGER -- Interests of Certain Persons in the Merger."
 
MANAGEMENT OF AFC AFTER THE MERGER
 
     The Merger Agreement provides that, at the Effective Time, the directors of
AFC and Astoria Federal, respectively, will be the directors of AFC and Astoria
Federal, respectively, immediately prior to the Effective Time of the Merger and
the directors of AFC and Astoria Federal will cause Mr. Gerard C. Keegan and one
other member of the GNYSB Board selected by GNYSB and acceptable to AFC and who
was a member of the GNYSB Board on the date of the Merger Agreement, to be
elected and appointed to the AFC Board and the board of directors of Astoria
Federal (the "Astoria Federal Board"). Except for the addition of
 
                                       17
<PAGE>   25
 
Mr. Keegan, the executive officers of AFC and Astoria Federal at the Effective
Time, respectively, will be the executive officers of AFC and Astoria Federal,
respectively, immediately prior to the Effective Time. At the Effective Time,
Mr. Keegan will become Vice Chairman and Chief Administrative Officer of AFC and
Astoria Federal. See "THE MERGER -- Interests of Certain Persons in the Merger"
and "-- Management of AFC After the Merger."
 
STOCK OPTION AGREEMENT
 
     As a condition to AFC entering into the Merger Agreement, AFC required that
GNYSB also enter into a Stock Option Agreement, dated as of March 29, 1997 (the
"Stock Option Agreement"), pursuant to which GNYSB granted AFC an option (the
"Option"), exercisable upon the occurrence of certain events (none of which has
occurred, to the best of AFC's and GNYSB's knowledge, as of the date hereof), to
purchase up to 2,721,536 shares of GNYSB Common Stock (representing
approximately 19.9% of the outstanding shares of GNYSB Common Stock on March 29,
1997), at an exercise price of $17.875 per share, subject to adjustment in
certain circumstances and subject to termination within certain periods. In
addition, the Merger Agreement provides that GNYSB shall in certain
circumstances pay to AFC a termination fee of $5 million in cash. However, the
maximum aggregate profit AFC can receive under the Stock Option Agreement and
the termination fee arrangement is $10 million. See "THE MERGER -- Price-Based
Termination."
 
     The Stock Option Agreement is intended to increase the likelihood that the
Merger will be consummated in accordance with the terms of the Merger Agreement.
Certain aspects of the Stock Option Agreement may have the effect of
discouraging persons who might now or prior to the consummation of the Merger be
interested in acquiring all of or a significant interest in GNYSB from
considering or proposing such an acquisition, even if such persons were prepared
to pay a higher price per share for the GNYSB Common Stock than the value per
share contemplated by the Merger Agreement. The acquisition of GNYSB or an
interest in GNYSB, or an agreement to do either, could cause the Option to
become exercisable. The existence of such Option could significantly increase
the cost to a potential acquiror of acquiring GNYSB compared to its cost had the
Stock Option Agreement not been entered into. Such increased costs might
discourage a potential acquiror from considering or proposing an acquisition or
might result in a potential acquiror proposing to pay a lower per share price to
acquire GNYSB than it might otherwise have proposed to pay. The management of
GNYSB believes that the exercise of the Option is likely to prohibit any
acquiror of GNYSB from accounting for any acquisition of GNYSB using the
pooling-of-interests accounting method for a period of two years. The inability
to use the pooling-of-interests accounting method could discourage or preclude
an acquisition by other banking organizations during that period.
 
     A copy of the Stock Option Agreement is attached as Appendix B to this
Joint Proxy Statement-Prospectus. A description of the Stock Option Agreement,
including a description of the events which will result in the Option becoming
exercisable, is set forth under "CERTAIN RELATED TRANSACTIONS -- Stock Option
Agreement -- Terms of Stock Option Agreement."
 
AMENDMENT TO GNYSB RIGHTS AGREEMENT
 
     On June 14, 1990, GNYSB adopted a Rights Agreement (the "GNYSB Rights
Agreement"), pursuant to which GNYSB's stockholders each received a dividend of
one GNYSB Right for each outstanding share of GNYSB Common Stock to holders of
record as of June 25, 1990. In connection with the execution of the Merger
Agreement, GNYSB amended the GNYSB Rights Agreement to clarify that for purposes
of determining whether AFC (as well as its affiliates and associates) is an
acquiring person, as defined in the GNYSB Rights Agreement, AFC shall not be
deemed to be a beneficial owner, as defined in the GNYSB Rights Agreement, or to
beneficially own any securities as a result of GNYSB's obligation to merge under
the Merger Agreement. See "CERTAIN RELATED TRANSACTIONS -- Amendment to GNYSB
Rights Agreement."

<PAGE>   26
 
CERTAIN DIFFERENCES IN STOCKHOLDERS' RIGHTS
 
     At the Effective Time, stockholders of GNYSB who receive shares of AFC
Common Stock will become stockholders of AFC and their rights as stockholders of
AFC will be determined by the Delaware General Corporation Law ("DGCL") and by
AFC's Certificate of Incorporation and Bylaws. The rights of GNYSB stockholders
are currently governed by the NYBL and by GNYSB's Restated Organization
Certificate and Bylaws. The rights of stockholders of AFC differ from rights of
the stockholders of GNYSB with respect to certain important matters, including:
the right to call special meetings; the right to take action by written consent;
the right to amend certain provisions of AFC's Certificate of Incorporation or
GNYSB's Restated Organization Certificate, as the case may be; appraisal rights;
the required stockholder vote as to certain matters; statutory and other
restrictions on certain business combinations; consideration of other
constituencies when evaluating a change of control; limitations of director and
officer liability; indemnification of directors and officers and provisions of
the rights agreements including triggering events. For a summary of these
differences, see "COMPARISON OF CERTAIN RIGHTS OF STOCKHOLDERS."
 
CERTIFICATE AMENDMENT
 
     In connection with the Merger Agreement, the AFC Board has approved the
Certificate Amendment to change the par value of AFC's authorized preferred
stock from $0.01 per share to $1.00 per share. Approval of the Certificate
Amendment requires the affirmative vote of holders of at least a majority of the
issued and outstanding shares of AFC Common Stock entitled to vote thereon. The
purpose of the increase in par value to $1.00 per share is to have available AFC
preferred stock that has the same par value as the GNYSB Series B Preferred
Stock so that the par value of the AFC Series B Preferred Stock is the same as
the GNYSB Series B Preferred Stock. The Certificate Amendment provides that at
such time as the AFC Series B Preferred Stock is no longer outstanding, the par
value of AFC Preferred Stock automatically, without any further action by AFC's
stockholders, will be reduced back to $0.01 per share. If approved, the
Certificate Amendment will be effective only upon consummation of the Merger.
Regardless of whether the Merger Agreement is approved by stockholders of GNYSB
or the issuance of the Merger Shares is approved by stockholders of AFC, failure
of AFC's stockholders to approve the Certificate Amendment will prevent
consummation of the Merger unless such condition is waived by GNYSB. See
"CERTIFICATE AMENDMENT."

                                  THE MEETINGS
 
GNYSB MEETING
 
     General.  Each copy of this Joint Proxy Statement-Prospectus mailed to
holders of GNYSB Common Stock and GNYSB Series A Preferred Stock is accompanied
by a white proxy card furnished in connection with the GNYSB Board's
solicitation of proxies for use at the GNYSB Meeting. The GNYSB Meeting is
scheduled to be held on August 1, 1997, at 9:30 a.m., Eastern Time, at The Grand
Prospect Hall, 263 Prospect Avenue, Brooklyn, New York 11215. At the GNYSB
Meeting, stockholders will consider and vote upon (i) a proposal to approve the
Merger Agreement and (ii) the Additional Proposal. See "ADDITIONAL PROPOSAL."
 
     HOLDERS OF GNYSB COMMON STOCK AND GNYSB SERIES A PREFERRED STOCK ARE
REQUESTED TO PROMPTLY COMPLETE, SIGN AND DATE THE ACCOMPANYING WHITE PROXY CARD
AND RETURN IT PROMPTLY TO GNYSB IN THE ENCLOSED POSTAGE-PAID, ADDRESSED
ENVELOPE.
 
     GNYSB STOCKHOLDERS SHOULD NOT FORWARD ANY STOCK CERTIFICATES WITH THEIR
PROXY CARDS.
 
     Recommendation of the Board of Directors.  THE GNYSB BOARD HAS APPROVED THE
MERGER AGREEMENT AND HAS DETERMINED THAT THE MERGER IS IN THE BEST INTERESTS OF
GNYSB AND ITS STOCKHOLDERS. THE GNYSB BOARD THEREFORE UNANIMOUSLY RECOMMENDS
THAT GNYSB'S STOCKHOLDERS VOTE FOR APPROVAL OF THE MERGER AGREEMENT AND THE
ADDITIONAL PROPOSAL.
 
     See "THE MERGER -- Background of and Reasons for the Merger -- GNYSB's
Reasons for the Merger."
 
     Record Date.  The GNYSB Board has fixed the close of business on June 19,
1997 as the record date for the determination of holders of GNYSB Common Stock
and GNYSB Series A Preferred Stock entitled to receive notice of and to vote at
the GNYSB Meeting. Only holders of record of GNYSB Common Stock and GNYSB Series
A Preferred Stock at the close of business on the GNYSB Record Date are entitled
to receive notice of and to vote at the GNYSB Meeting.
 
     Voting and Solicitation of Proxies.  GNYSB stockholders will be entitled to
one vote for each share of GNYSB Common Stock and GNYSB Series A Preferred Stock
held of record as of the close of business on the GNYSB Record Date on each
matter to be voted upon at the GNYSB Meeting. The presence in person or by proxy
of the holders of at least a majority of the aggregate number of shares
outstanding of GNYSB Common Stock and GNYSB Series A Preferred Stock on the
GNYSB Record Date is necessary to constitute a quorum at the GNYSB Meeting.
Holders of GNYSB Series B Preferred Stock are not entitled to vote at the GNYSB
Meeting.
 
     The shares of GNYSB Common Stock and GNYSB Series A Preferred Stock
represented by properly executed proxies received at or prior to the GNYSB
Meeting and not subsequently revoked prior to the vote at the GNYSB Meeting will
be voted as directed in such proxies. IF INSTRUCTIONS ARE NOT GIVEN, SHARES
REPRESENTED BY PROPERLY EXECUTED PROXIES WILL BE VOTED FOR APPROVAL AND ADOPTION
OF THE MERGER AGREEMENT AND FOR THE ADDITIONAL PROPOSAL. However, no proxy which
is voted against the proposal to approve the Merger Agreement will be voted in
favor of the Additional Proposal by the proxies pursuant to such discretion.
 
     Any holder of GNYSB Common Stock or GNYSB Series A Preferred Stock who has
executed and delivered a proxy may revoke it at any time before it is voted by
attending the GNYSB Meeting and voting in person or by giving notice of
revocation in writing or submitting a signed proxy card bearing a later date to
GNYSB, at its administrative headquarters at One Penn Plaza, New York, New York
10119, provided that such notice or proxy card is actually received by GNYSB
before the vote of stockholders. A proxy will not be revoked by death or
supervening incapacity of the stockholder executing the proxy unless, before the
vote, notice of such death or incapacity is filed with the Corporate Secretary
or other person responsible for tabulating votes on behalf of GNYSB.

     The cost of soliciting proxies from holders of GNYSB Common Stock and GNYSB
Series A Preferred Stock in the form enclosed herewith will be borne by GNYSB.
Such solicitation will be made by mail but also may be made by telephone or in
person by the directors, officers and employees of GNYSB (who will receive no
additional compensation for doing so). GNYSB has retained Georgeson & Company,
Inc. to assist in such solicitation. The fee to be paid to such firm is not
expected to exceed $20,000, plus reasonable out-of-pocket costs and expenses
authorized by GNYSB. In addition, GNYSB will make arrangements with brokerage
firms and other custodians, nominees and fiduciaries to send proxy materials to
their principals and will reimburse such parties for their expenses in doing so.
 
     A representative of GNYSB's independent auditors, KPMG Peat Marwick LLP,
will not be present at the GNYSB Meeting.
 
     Vote Required.  The affirmative vote of two-thirds of the aggregate
outstanding shares on the GNYSB Record Date of GNYSB Common Stock and GNYSB
Series A Preferred Stock entitled to vote at the GNYSB Meeting, voting as a
single class, is required in order to approve and adopt the Merger Agreement. In
addition, the affirmative vote of a majority of the votes present in person or
by proxy and entitled to vote at the GNYSB Meeting is required to approve the
Additional Proposal. A failure to return a properly executed proxy card or to
vote in person or abstaining from voting will have the same effect as a vote
against the Merger Agreement. An abstention, with respect to the Additional
Proposal, will have the effect of a vote against the Additional Proposal. Broker
non-votes will not be counted as having been voted in person or by proxy at the
GNYSB Meeting and will have the same effect as a vote against the Merger
Agreement. In contrast, shares underlying broker non-votes will have no effect
on the vote on the Additional Proposal. As of the GNYSB Record Date, there were
a total of 13,714,485 shares of GNYSB Common Stock and 1,477,802 shares of GNYSB
Series A Preferred Stock outstanding and entitled to be voted at the GNYSB
Meeting.
 
     As of April 30, 1997, GNYSB's directors and executive officers (and their
affiliates) (22 persons) beneficially owned and had the power to vote 271,109
shares of GNYSB Common Stock, beneficially owned, but did not have the right to
vote approximately 84,133 shares of GNYSB Common Stock held in the GNYSB
Incentive Savings Plan and had a beneficial interest in, and the right to direct
the voting of, approximately 143,195 shares of GNYSB Common Stock and GNYSB
Series A Preferred Stock held in the GNYSB ESOP accounts. Such shares of GNYSB
Common Stock and GNYSB Series A Preferred Stock which GNYSB directors and
executive officers (and their affiliates) have the right to vote, or direct the
voting thereof, represent approximately 2.73%, as of April 30, 1997, of the
outstanding GNYSB Common Stock and GNYSB Series A Preferred Stock which may be
voted at the GNYSB Meeting. Such persons have indicated their intention to vote,
or direct the voting of, all such shares, in favor of the Merger Agreement and
for the Additional Proposal. See "BENEFICIAL OWNERSHIP OF GNYSB COMMON STOCK."
The Trustee of the GNYSB ESOP is obligated to vote unallocated shares and shares
for which no direction has been received in the same proportion as shares for
which such voting directions have been received from participants so long as
such vote is in accordance with the provisions of ERISA. As of April 30, 1997,
AFC, its subsidiaries, and the directors and executive officers of AFC,
beneficially owned 240,000 shares, or approximately 1.75%, of GNYSB Common
Stock. Such persons have indicated their intention to vote, or direct the voting
of, all such shares, in favor of the Merger Agreement and for the Additional
Proposal.

     Recommendation of the Board of Directors.  THE AFC BOARD HAS UNANIMOUSLY
APPROVED THE MERGER AGREEMENT AND HAS DETERMINED THAT THE MERGER, THE ISSUANCE
OF THE MERGER SHARES PURSUANT THERETO AND THE CERTIFICATE AMENDMENT ARE IN THE
BEST INTERESTS OF AFC AND ITS STOCKHOLDERS. THE AFC BOARD THEREFORE UNANIMOUSLY
RECOMMENDS THAT AFC'S STOCKHOLDERS VOTE FOR APPROVAL OF THE ISSUANCE OF THE
MERGER SHARES, THE CERTIFICATE AMENDMENT AND THE ADDITIONAL PROPOSAL.
 
     See "THE MERGER -- Background of and Reasons for the Merger -- AFC's
Reasons for the Merger."
 
     Record Date.  The AFC Board has fixed the close of business on June 23,
1997 as the record date for the determination of holders of AFC Common Stock
entitled to receive notice of and to vote at the AFC Meeting. Only holders of
record of AFC Common Stock at the close of business on the AFC Record Date are
entitled to receive notice of and to vote at the AFC Meeting.
 
     Voting and Solicitation of Proxies.  AFC stockholders will be entitled to
one vote for each share of AFC Common Stock held of record as of the close of
business on the AFC Record Date on each matter to be voted upon at the AFC
Meeting. The presence in person or by proxy of the holders of at least a
majority of the total number of shares of AFC Common Stock outstanding on the
AFC Record Date is necessary to constitute a quorum at the AFC Meeting.
 
     The shares of AFC Common Stock represented by properly executed proxies
received at or prior to the AFC Meeting and not subsequently revoked prior to
the vote at the AFC Meeting will be voted as directed in such proxies. IF
INSTRUCTIONS ARE NOT GIVEN, SHARES REPRESENTED BY PROPERLY EXECUTED PROXIES WILL
BE VOTED FOR APPROVAL OF THE ISSUANCE OF THE MERGER SHARES, THE CERTIFICATE
AMENDMENT AND THE ADDITIONAL PROPOSAL. However, no proxy which is voted against
the proposal to approve the issuance of the Merger Shares or the Certificate
Amendment will be voted in favor of the Additional Proposal by the proxies
pursuant to such discretion.
 
     Any holder of AFC Common Stock who has executed and delivered a proxy may
revoke it at any time before it is voted by attending and voting in person at
the AFC Meeting or by giving written notice of revocation or submitting a signed
proxy card bearing a later date to AFC, at One Astoria Federal Plaza, Lake
Success, New York 11042, attention: Corporate Secretary, provided that such
notice or proxy card is actually received by AFC prior to the vote of
stockholders.
 
     The cost of soliciting proxies from holders of AFC Common Stock in the form
enclosed herewith will be borne by AFC. Such solicitation will be made by mail
but also may be made by telephone or in person by the directors, officers or
employees of AFC (who will receive no additional compensation for doing so). AFC
has retained Kissell-Blake, Inc. to assist in such solicitation. The fee to be
paid to such firm is not expected to exceed $5,000, plus reasonable
out-of-pocket costs and expenses. In addition, AFC will make arrangements with
brokerage firms and other custodians, nominees and fiduciaries to send proxy
materials to their principals and will reimburse such parties for their expenses
in doing so.
 
     A representative of AFC's independent auditors, KPMG Peat Marwick LLP, will
not be present at the AFC Meeting.
 
     Vote Required.  Assuming a quorum is present at the AFC Meeting, the
affirmative vote of the holders of a majority of the total votes cast at the AFC
Meeting and entitled to vote thereon is required for approval of the issuance of
the Merger Shares and the Additional Proposal and the affirmative vote of the
holders of a majority of shares of AFC Common Stock outstanding is required for
approval of the Certificate Amendment. Shares represented at the AFC Meeting and
abstaining from voting will be counted as shares represented at the AFC Meeting.
Therefore an abstention will have the same effect as a vote against the issuance
of the Merger Shares, the Certificate Amendment and the Additional Proposal.
Broker non-votes will not be counted as having been voted in person or by proxy
at the AFC Meeting and will have the same effect as a vote against the
Certificate Amendment, but will have no effect on the vote on the issuance of
the Merger Shares or the Additional Proposal. As of the AFC Record Date, there
were 20,972,257 shares of AFC Common Stock outstanding and entitled to vote at
the AFC Meeting.

beneficially owned, as of April 30, 1997, 2,081,461 shares, or approximately

indicated a present intent to vote their shares in favor of approval of the
issuance of the Merger Shares, the Certificate Amendment and the Additional
Proposal. See "BENEFICIAL OWNERSHIP OF AFC COMMON STOCK." As of April 30, 1997,
the directors and executive officers of GNYSB and their affiliates beneficially
owned 1,304 shares of AFC Common Stock.
 
                                   THE MERGER
 
     The following information, insofar as it relates to matters contained in
the Merger Agreement or the Stock Option Agreement, is qualified in its entirety
by reference to the Merger Agreement and the Stock Option Agreement, which are

herein by reference. AFC and GNYSB stockholders are urged to read the Merger
Agreement and the Stock Option Agreement in their entirety.

reorganization will not occur.
 
EFFECTS OF THE MERGER
 
     Pursuant to the terms of the Merger Agreement, subject to the satisfaction
or waiver (where permissible) of certain conditions, including, among other
things, the receipt of all necessary regulatory approvals, the
 
                                       30
<PAGE>   38
 
expiration of all waiting periods in respect thereof, the approval of the Merger
Agreement by the requisite vote of the stockholders of GNYSB and the approval of
the issuance of the Merger Shares and the Certificate Amendment by the requisite
vote of the stockholders of AFC, GNYSB will be merged with and into Astoria
Federal. GNYSB stockholders will receive the consideration described below in
"-- Merger Consideration and Election, Allocation and Proration Procedures."
Astoria Federal shall be the surviving corporation in the Merger. Upon
consummation of the Merger, the separate corporate existence of GNYSB shall
terminate.
 
     Each outstanding share of AFC Common Stock at the Effective Time will
remain outstanding and unchanged as a result of the Merger.
 
EFFECTIVE TIME
 
     The Merger will become effective at the date and time set forth in the
articles of combination which will be filed with the OTS in accordance with
applicable law. The articles of combination will be filed not later than the
last business day of the month in which the expiration of the last applicable
waiting period in connection with approvals of governmental authorities shall
occur and all conditions to the consummation of the Merger Agreement are
satisfied or waived and will be effective after the close of business on such
date, unless another date is agreed to in writing by AFC and GNYSB (the "Closing
Date"). See "-- Conditions to the Consummation of the Merger." It is expected
that a period of time will elapse between the Meetings and the Effective Time
while the parties seek to obtain the regulatory approvals required to consummate
the Merger. There can be no assurance that such regulatory approvals will be
obtained, and if obtained, there can be no assurance as to the date of any such
approval. There can likewise be no assurance that the United States Department
of Justice or the New York State Attorney General will not challenge the Merger
or, if such a challenge is made, as to the result thereof. See "-- Regulatory
Approvals."
 
MERGER CONSIDERATION AND ELECTION, ALLOCATION AND PRORATION PROCEDURES
 
     General.  The Merger Agreement provides that the aggregate consideration
payable to holders of GNYSB Common Stock in the Merger will consist of 0.5 of a
share of AFC Common Stock per share of GNYSB Common Stock for 75% of the shares
of GNYSB Common Stock and $19.00 in cash per share of GNYSB Common Stock for the
remaining 25% of the shares of GNYSB Common Stock. Each share of GNYSB Common
Stock will be converted in the Merger into the right to receive: (i) 0.5 of a
share of AFC Common Stock, (ii) $19.00 in cash or (iii) a combination of cash
and a fraction of a share of AFC Common Stock determined as provided below. The
actual consideration ultimately received by a stockholder for shares of GNYSB
Common Stock will depend upon the election, allocation and proration procedures
described below and the election of other stockholders. The Merger Consideration
may be increased by AFC in the event GNYSB exercises its rights under the Merger
Agreement to deliver to AFC a notice to terminate the Merger Agreement due to
the price of the AFC Common Stock declining below certain levels established by
formulas set forth in the Merger Agreement. See "THE MERGER -- Price Based
Termination."
 
     Elections.  Within three days after the consummation of the Merger, each
record holder of GNYSB Common Stock will be sent materials asking such
stockholder to elect (an "Election") to receive for its shares of GNYSB Common
Stock:
 
          (i) 0.5 of a share of AFC Common Stock for each share of GNYSB Common
     Stock (a "Stock Election");
 
          (ii) $19.00 in cash without interest for each share of GNYSB Common
     Stock (a "Cash Election");
 
          (iii) a Stock Election with respect to some of such stockholder's
     shares of GNYSB Common Stock and a Cash Election with respect to the
     remaining shares of GNYSB Common Stock held by such holder; or
 
          (iv) whatever is left after the election of the other holders of GNYSB
     Common Stock and the application to the extent necessary of certain random
     selection procedures (a "No-Election").
 
                                       31
<PAGE>   39
 
     Notwithstanding the foregoing, in order to make a Stock Election, the
number of shares of GNYSB Common Stock a holder must elect to convert to AFC
Common Stock must equal or exceed 100 shares. Therefore, any holder of GNYSB
Common Stock who owns less than 100 shares must elect the Cash Election or be
treated as having made a No-Election. A failure to properly make an election as
described below will be treated as a No-Election.
 
     NO GAIN OR LOSS WILL BE RECOGNIZED BY HOLDERS OF GNYSB COMMON STOCK AS A
RESULT OF THE MERGER, EXCEPT WHERE ANY CASH CONSIDERATION IS RECEIVED OR TO THE
EXTENT OF ANY CASH RECEIVED IN LIEU OF A FRACTIONAL SHARE INTEREST IN AFC COMMON
STOCK. SEE "THE MERGER -- MATERIAL FEDERAL INCOME TAX CONSEQUENCES."
 
     No Oversubscription.  In the event that the number of shares as to which a
Cash Election has been made does not exceed 25% of the shares of GNYSB Common
Stock outstanding at the Effective Time and the number of shares as to which a
Stock Election has been made does not exceed 75% of the shares of GNYSB Common
Stock outstanding at the Effective Time, then:
 
          (i) all shares as to which a Cash Election has been made shall be
     converted into the right to receive $19.00 in cash without interest per
     share of GNYSB Common Stock;
 
          (ii) all shares as to which a Stock Election has been made shall be
     converted into the right to receive 0.5 of a share of AFC Common Stock per
     share of GNYSB Common Stock; and
 
          (iii) shares as to which No-Election has been made shall be converted
     into either the right to receive 0.5 of a share of AFC Common Stock per
     share of GNYSB Common Stock or $19.00 per share of GNYSB Common Stock as
     determined by random selection so that 25% of the shares of GNYSB Common
     Stock are converted into the right to receive cash and 75% of the shares of
     GNYSB Common Stock are converted into the right to receive AFC Common
     Stock.
 
     The random selection process to be used by the Exchange Agent will consist
of drawing by lot or such other process as the Exchange Agent deems equitable
and necessary to effect the allocations described above.
 
     Oversubscription for Cash.  If the aggregate number of shares as to which a
Cash Election has been made exceeds 25% of the shares of GNYSB Common Stock
outstanding at the Effective Time, then:
 
          (i) each share as to which a Stock Election has been made and each
     share as to which No-Election has been made shall be converted into the
     right to receive 0.5 of a share of AFC Common Stock; and
 
          (ii) each share as to which a Cash Election has been made shall be
     converted into the right to receive a combination of cash and AFC Common
     Stock. The amount in cash will be equal to the product, rounded to the
     nearest $0.01, of (x) $19.00 and (y) a fraction (the "Cash Fraction"), the
     numerator of which shall be a number equal to 25% of the shares of GNYSB
     Common Stock outstanding at the Effective Time and the denominator of which
     shall be the total number of shares as to which a Cash Election has been
     made. The number of shares of AFC Common Stock will be equal to the
     product, rounded to four decimal places, of (x) 0.50 and (y) a number equal
     to one minus the Cash Fraction. For example, if the aggregate number of
     shares as to which a Cash Election has been made equals 50%, 75% or 100% of
     the shares of GNYSB Common Stock, the combination would consist of $9.50 in
     cash and 0.25 of a share of AFC Common Stock, $6.33 in cash and 0.3333 of a
     share of AFC Common Stock and $4.75 in cash and 0.375 of a share of AFC
     Common Stock, respectively.
 
     Oversubscription for AFC Common Stock.  If the aggregate number of shares
as to which a Stock Election has been made exceeds 75% of the shares of GNYSB
Common Stock outstanding at the Effective Time, then:
 
          (i) each share as to which a Cash Election has been made and each
     share as to which No-Election has been made shall be converted into the
     right to receive $19.00 in cash without interest; and
 
          (ii) each share as to which a Stock Election has been made shall be
     converted into the right to receive a combination of cash and AFC Common
     Stock. The number of shares of AFC Common Stock will be equal to the
     product, rounded to four decimal places, of (x) 0.50 and (y) a fraction
     (the "Stock Fraction"), the numerator of which shall be a number equal to
     75% of the shares of GNYSB Common
 
                                       32
<PAGE>   40
 
     Stock outstanding at the Effective Time and the denominator of which shall
     be the total number of shares as to which a Stock Election has been made.
     The amount of cash will be equal to the product, rounded to the nearest
     $0.01, of (x) $19.00 and (y) a number equal to one minus the Stock
     Fraction. For example, if the aggregate number of shares as to which a
     Stock Election has been made equals 90% or 100% of the shares of GNYSB
     Common Stock, the combination would consist of 0.4167 of a share of AFC
     Common Stock and $3.17 in cash and 0.375 of a share of AFC Common Stock and
     $4.75 in cash, respectively.
 
     No Guarantee of Chosen Consideration or Equivalent Value.  Because the
Merger provides that the aggregate consideration payable to holders of GNYSB
Common Stock in the Merger will be fixed such that it consists of 0.5 of a share
of AFC Common Stock per share of GNYSB Common Stock for 75% of the shares of
GNYSB Common Stock and $19.00 in cash per share of GNYSB Common Stock for the
remaining 25% of the shares of GNYSB Common Stock, no guarantee can be given
that the election of any given stockholder of GNYSB will be honored. Rather, the
election by each stockholder will be subject to the election, allocation and
proration procedures described herein. Thus stockholders may not receive their
requested form of consideration or combination thereof. Because the market price
of AFC Common Stock may fluctuate and it could be greater than or less than
$38.00 per share (the price at which the market value of 0.5 of a share of AFC
Common Stock would equal the cash consideration of $19.00 per share), the market
value of 0.5 of a share of AFC Common Stock received per share could be less
than or greater than the cash price per share of $19.00.
 
     Election Procedures.  All Elections will be required to be made on a Letter
of Transmittal and Election Form. To make an effective Election with respect to
shares of GNYSB Common Stock, the holder thereof must, in accordance with the
Letter of Transmittal and Election Form, (i) complete properly and return the
Letter of Transmittal and Election Form to the Exchange Agent, (ii) either (a)
deliver therewith his or her certificates representing shares of GNYSB Common
Stock (the "GNYSB Stock Certificates") with respect to such shares (or an
appropriate guarantee of delivery thereof), or (b) complete the procedure for
delivery by book-entry transfer of such shares on a timely basis, and (iii)
deliver therewith any other required documents, prior to 5:00 p.m. on the 10th
business day following mailing of the Letter of Transmittal and Election Form
(the "Election Deadline").
 
     GNYSB STOCK CERTIFICATES SHOULD NOT BE RETURNED WITH THE ENCLOSED PROXY AND
SHOULD NOT BE FORWARDED TO THE EXCHANGE AGENT UNTIL A GNYSB STOCKHOLDER HAS
RECEIVED THE LETTER OF TRANSMITTAL AND ELECTION FORM.
 
     A holder of shares of GNYSB Common Stock having a preference as to the form
of consideration to be received for his or her shares of GNYSB Common Stock
should make an Election because shares as to which an Election has been made
will be given priority in allocating such consideration over shares as to which
an Election is not received. Neither GNYSB nor the GNYSB Board makes any
recommendation as to whether stockholders should elect to receive the Cash
Consideration or the Stock Consideration in the Merger. Each holder of GNYSB
Common Stock must make his or her own decision with respect to such election.
 
     GNYSB Series A Preferred Stock.  All of the shares of the GNYSB Series A
Preferred Stock are held by the GNYSB ESOP Trustee. The shares held in the GNYSB
ESOP and allocated to participants' accounts are voted by the beneficial owners
of such shares based on directions received from such beneficial owners by the
trustee of the GNYSB ESOP. Unallocated shares and any allocated shares with
respect to which no voting instructions have been received will be voted by the
trustee of the GNYSB ESOP in the same manner and proportion as the allocated
shares with respect to which voting instructions have been received, as long as
such vote is in accordance with the provisions of ERISA.
 
     1,477,802 shares of GNYSB Series A Preferred Stock were outstanding on the
Record Date, but may be redeemed or converted into shares of GNYSB Common Stock
at any time after the date of this Joint Proxy Statement-Prospectus and prior to
the anticipated closing date of the Merger. The Merger Agreement requires that
if certain conditions are satisfied GNYSB is obligated to redeem all of the
shares of the GNYSB Series A Preferred Stock prior to the consummation of the
Merger. These conditions include (i) the approval of the Merger Agreement and
related transactions by the holders of GNYSB and AFC stock entitled to vote
thereon, (ii) the receipt of all required regulatory approvals, (iii) the waiver
by AFC of all conditions to its
 
                                       33
<PAGE>   41
 
obligations to consummate the Merger and (iv) a market price of AFC Common Stock
of at least $34.125. The redemption price in effect after July 1, 1997 for the
GNYSB Series A Preferred Stock is $13.20 plus accrued dividends to the date of
redemption. The effectiveness of such redemption is a condition to the
consummation of the Merger. GNYSB may, of its own accord, provide a notice of
redemption to the GNYSB ESOP Trustee at any time. However, it has not yet done
so because it was determined that it was in the best interest of both GNYSB and
the GNYSB ESOP and its participants to receive a dividend for the full semi-
annual period ending June 30, 1997. AFC has requested that GNYSB exercise its
right to call the GNYSB Series A Preferred Stock for redemption prior to the
time frames set forth in the Merger Agreement, and GNYSB has advised AFC that it
will consider exercising such right to cause a redemption to occur shortly after
the payment of such dividend. However, no assurance can be given that GNYSB will
exercise such right within such time frame. As long as the market price of the
GNYSB Common Stock exceeds approximately $14.00, GNYSB expects that the GNYSB
ESOP Trustee will, in lieu of allowing such shares to be redeemed for cash,
convert such shares into shares of GNYSB Common Stock with a conversion ratio of
0.9448 of a share of GNYSB Common Stock for each share of GNYSB Series A
Preferred Stock. Notwithstanding the foregoing, GNYSB intends to seek the GNYSB
ESOP Trustee's agreement to convert the GNYSB Series A Preferred Stock prior to
the time GNYSB is obligated to redeem such shares. Shares of GNYSB Common Stock
held by the GNYSB ESOP at the Effective Time will be subject to the election,
allocation and proration procedures in the same manner as all other shares of
GNYSB Common Stock. AFC intends to enforce its rights to require the issuance of
a notice of redemption to the GNYSB ESOP Trustee, which will require the GNYSB
ESOP Trustee to choose either to allow such redemption or exercise its right of
conversion at the conversion ratio of .9448 per share. However, if for any
reason AFC does not do so and GNYSB does not of its own accord exercise its
right to call the GNYSB Series A Preferred Stock for redemption, the GNYSB
Series A Preferred Stock outstanding at the Effective Time of the Merger, under
the Certificate of Designations, would be deemed immediately prior to the
Effective Time to have been converted into shares of GNYSB Common Stock at a
prescribed conversion ratio.
 
     GNYSB Series B Preferred Stock.  Upon consummation of the Merger, the
outstanding shares of GNYSB Series B Preferred Stock will be converted into the
AFC Series B Preferred Stock, a newly-created series of preferred stock of AFC
with substantially identical and no less favorable terms.
 
     Miscellaneous.  If AFC effects a stock dividend, reclassification,
recapitalization, split-up, combination, exchange of shares or similar
transaction prior to the Effective Time, an appropriate adjustment to the
consideration will be made.
 
     No fractional shares of AFC Common Stock will be issued in connection with
the Merger and cash will be paid in lieu thereof.
 
     Upon consummation of the Merger, any shares of GNYSB Common Stock that are
owned by GNYSB as treasury stock or that are held directly or indirectly by AFC
other than in a fiduciary capacity or in satisfaction of a debt previously
contracted will be canceled and retired and no payment will be made with respect
thereto and such shares will not be considered for purposes of the foregoing. In
addition, shares of GNYSB Common Stock with respect to which dissenters' rights
have been asserted and not withdrawn will not be converted into the right to
receive cash or AFC Common Stock as provided in the Merger Agreement and will be
considered No-Election Shares for purposes of applying the allocation and
proration procedures described herein. For certain information concerning the
historical market prices of GNYSB Common Stock and AFC Common Stock, see
"COMPARATIVE COMMON STOCK PRICE AND DIVIDEND INFORMATION."
 
     Dissenting Stockholders.  Any Dissenting Shares shall not be converted into
the right to receive the Merger Consideration unless and until the holder shall
have failed to perfect, or shall have effectively withdrawn or lost, his right
to dissent. If any such holder shall have so failed to perfect or shall have
effectively withdrawn or lost such right, each share of such holder's GNYSB

BACKGROUND OF AND REASONS FOR THE MERGER
 
     Background of the Merger.  In early January of 1997, Mr. George L. Engelke,
Jr., the chief executive officer of AFC, called Mr. Gerard C. Keegan, the chief
executive officer of GNYSB, to request a meeting. After informing the GNYSB
Board at a regularly scheduled meeting on January 22, 1997, Mr. Keegan agreed to
meet with Mr. Engelke on January 23, 1997. At this meeting, Mr. Engelke raised
with Mr. Keegan the concept of a possible combination between AFC and GNYSB. Mr.
Keegan informed the GNYSB Board of Mr. Engelke's interest at a regularly
scheduled meeting of the GNYSB Board on February 13, 1997. Although the GNYSB
Board recognized that there may well be a strategic fit between the two
institutions and strategic benefits to such a combination, it declined to pursue
Mr. Engelke's interest because of the general nature of the interest and absence
of specifics as to a proposed combination and the manner in which it would be
executed and implemented. Mr. Keegan called Mr. Engelke on February 14, 1997 and
informed him of the GNYSB Board's determination.
 
     On March 7, 1997, Mr. Engelke again contacted Mr. Keegan to arrange a
meeting to discuss a possible combination. He indicated that, despite GNYSB's
earlier rejection, his further consideration of a strategic business combination
with GNYSB led him to conclude that there were even more compelling reasons for
a combination than he had initially thought and that such a combination would
provide significant benefits to both organizations and their shareholders. At a
GNYSB Board meeting held on March 13, 1997, it was decided that Mr. Keegan
should meet again with Mr. Engelke and hear what he had to say. As a result, Mr.
Engelke and Mr. Keegan met on March 16, 1997. At this meeting, Mr. Engelke
explained to Mr. Keegan, among other things, (i) the strategic focus and plan of
AFC and how he believed GNYSB and its operations were consistent with and would
facilitate such strategic focus and plan, (ii) the complementary nature of AFC's
and GNYSB's branch networks (location and product mix, as well as service
orientation) and how a combination of those branch networks could strengthen a
combined organization, (iii) AFC's views, approaches and commitments to the
communities and customers it serves and its employees and how they were similar
to GNYSB's and (iv) certain economic effects and implications of a possible
combination, including cost savings, and the general effect the foregoing could
have on the combined organization and its shareholders. After a discussion of
the foregoing, and the benefits it would have, Mr. Engelke indicated to Mr.
Keegan that AFC would be willing to pursue a negotiated strategic combination on
an expedited basis with GNYSB at a price of approximately $18 per share in part
cash and part AFC Common Stock and that AFC would be willing to consider a
higher price subject in each case to the results of its due diligence as well as
various different combinations of cash and AFC Common Stock.
 
     On March 17, 1997, Mr. Keegan received a call from the chief executive
officer of another banking organization (the "Other Organization") expressing an
interest in acquiring GNYSB.
 
     Mr. Keegan reported the contact with the chief executive officer of the
Other Organization to the GNYSB Board at a special meeting on March 17, 1997. At
this meeting, he also reported the results of his meeting with Mr. Engelke and
the GNYSB Board authorized the further consideration of a possible combination
with AFC, including due diligence on GNYSB and AFC, and the further
consideration of GNYSB's strategic alternatives. The GNYSB Board authorized the
further consideration of a possible combination with AFC at such time in part
because of its assessment regarding AFC's strategic plan and focus and how GNYSB
and its operations were consistent with such focus and plan, the branch network
strengths of a combined organization, the similarity in AFC's and GNYSB's views,
approaches and commitments to the communities and customers they each serve and
their respective employees, the strategic benefits that a possible combination
would have on the combined organization and AFC's stated willingness to pursue a
negotiated strategic combination on an expedited basis with GNYSB at a price of
approximately $18 per share with the possibility that such price could be higher
and with flexibility with respect to any cash/stock mix.
 
     Subsequently, the chief executive officer of the Other Organization
initiated a series of telephone calls with Mr. Keegan and GNYSB's investment
bankers, Sandler O'Neill, regarding its interest in GNYSB and seeking the
opportunity to make a proposal regarding a possible business combination with
GNYSB. As part of these discussions and at the request of GNYSB, the Other
Organization submitted a letter intended to address its views on how an
acquisition by it would impact the communities and customers served by GNYSB and
its employees.

     Discussions and negotiations concerning a possible combination with AFC and
due diligence by both parties continued through a special meeting of the GNYSB
Board on Thursday March 27, 1997 attended by representatives of Sandler O'Neill,
GNYSB's counsel and the GNYSB Board's counsel at which there was before the
GNYSB Board a proposal by AFC to combine with GNYSB. This proposal involved the
exchange by AFC of $19.00 in cash per share for 25% of the shares of GNYSB
Common Stock and AFC Common Stock with a value of approximately $19.00 per share
for 75% of the shares of GNYSB Common Stock in a combination accounted for as a
"purchase." Based on the closing price of AFC Common Stock of $38.75 per share
on March 26 (the day prior to the meeting), this represented an exchange ratio
of 0.4903 of a share of AFC Common Stock per share of GNYSB Common Stock. At
this meeting, the GNYSB Board considered, among others, the strategic
alternatives available to GNYSB, the AFC proposal and the alternatives to the
AFC proposal, including a possible combination with the Other Organization, and
their feasibility.
 
     As part of the GNYSB Board's deliberations, it instructed Sandler O'Neill
to contact the Other Organization to inquire as to the consideration it would be
willing to provide to GNYSB's shareholders in a combination with GNYSB and its
ability to move expeditiously to sign a definitive agreement with respect to
such a transaction. The Other Organization responded with a proposal that
involved a combination conditioned on "pooling of interests" accounting
treatment and consideration consisting of a fixed exchange ratio of the Other
Organization's common stock that had a value of $18.53 per share of GNYSB Common
Stock based on the closing price of the Other Organization's common stock on
March 27, 1997. Sandler O'Neill asked the Other Organization to increase its
price and it declined to do so. The Other Organization also indicated that it
could move expeditiously to enter into a definitive agreement. This proposal was
immediately communicated to the GNYSB Board.
 
     As a result of a decline in the closing price of AFC Common Stock from
$38.75 on March 26, 1997 to $37.875 on March 27, 1997, the value of the exchange
ratio of 0.4903 of a share of AFC Common Stock for each share of GNYSB Common
Stock declined from $19.00 to $18.57. In light of this decline, GNYSB requested
AFC to increase the exchange ratio to reflect a value of $19.00 per share based
on the closing price of AFC Common Stock on March 27, 1997. AFC indicated that
it would be willing to increase the fixed exchange ratio in its proposal to 0.5,
but demanded, in return, that it be granted a stock option for 19.9% of GNYSB
Common Stock, which was intended to increase the likelihood that the Merger will
be consummated in accordance with the Merger Agreement. This increased exchange
ratio had a value of $18.94 based on the closing price of AFC Common Stock on
March 27, 1997, the last trading day prior to the announcement of the Merger.
 
     A special meeting of the AFC Board was held on Thursday, March 27, 1997
attended by representatives of Merrill Lynch and AFC's counsel. At the meeting,
there was before the AFC Board a proposal to authorize Mr. Engelke to finalize a
definitive agreement for the merger of GNYSB with Astoria Federal on the terms
presented at the meeting, which proposal was unanimously approved by the AFC
Board. The material terms presented at the meeting included pricing, the Stock
Option Agreement, termination provisions, standard representations and
warranties, negative covenants, customary closing conditions, honoring any
existing employment agreements between GNYSB and its officers, the cash-out of
existing stock options of GNYSB, the creation of an advisory board, the addition
of two directors of GNYSB to the AFC Board and Mr. Keegan becoming an officer of
AFC and Astoria Federal with the title of Vice Chairman and Chief Administrative
Officer.
 
     On Saturday March 29, 1997, the GNYSB Board held a special meeting with
representatives of Sandler O'Neill, GNYSB's counsel and the GNYSB Board's
counsel to further consider the AFC proposal and its alternatives. Sandler
O'Neill rendered its oral opinion, subsequently confirmed in writing, that, as
of such date, the consideration to be received in the Merger by the holders of
GNYSB Common Stock, including the shares of GNYSB Common Stock issued upon the
conversion of GNYSB Series A Preferred Stock and GNYSB Series B Preferred Stock,
was fair to the holders thereof from a financial point of view. After an
extensive discussion, the GNYSB Board unanimously determined, based on the
consideration of the various factors discussed below, to accept the AFC
proposal.
 
     GNYSB's Reasons for the Merger.  The GNYSB Board has unanimously approved
the Merger Agreement and has determined that the Merger is in the best interests
of GNYSB and its stockholders. The
 
                                       36
<PAGE>   44
 
GNYSB Board therefore unanimously recommends that holders of GNYSB Common Stock
and GNYSB Series A Preferred Stock vote FOR the adoption and approval of the
Merger Agreement. The GNYSB Board believes that the Merger will enable holders
of GNYSB Common Stock and GNYSB Series A Preferred Stock to realize significant
value in part on a tax-free basis. In addition, the shareholders would receive a
higher dividend on the AFC Common Stock than that presently received on GNYSB
Common Stock. See "-- AFC's Reasons for the Merger" and "-- Opinions of
Financial Advisors -- GNYSB."
 
     In reaching its determination that the Merger and the Merger Agreement are
in the best interests of GNYSB and the holders of GNYSB Common Stock, GNYSB
Series A Preferred Stock and GNYSB Series B Preferred Stock, the GNYSB Board
considered during the course of its strategic deliberations a number of factors,
both from a short-term and a long-term perspective, including, without
limitation, the following:
 
          (i) The GNYSB Board's familiarity with and review of GNYSB's business,
     financial condition, results of operations and prospects, including, but
     not limited to, its level of non-performing assets and troubled debt
     restructurings, the quality of its loan portfolio and its potential growth,
     development, productivity and profitability;
 
          (ii) The current and prospective environment in which GNYSB operates,
     including national and local economic conditions, the competitive
     environment for banks and other financial institutions generally, the
     increased regulatory burden on financial institutions generally and the
     trend toward consolidation in the financial services industry;
 
          (iii) The GNYSB Board's review with its legal and financial advisors
     of alternatives to the Merger (including its review of the proposal made by
     the Other Organization and the possibility of remaining independent and
     growing internally);
 
          (iv) The GNYSB Board's review, based in part on presentations by GNYSB
     management and advisors, of AFC's business, financial condition, results of
     operations and management and the recent performance of the AFC Common
     Stock on both an historical and prospective basis, the strategic fit
     between the parties, the enhanced opportunities for operating efficiencies
     that could result from the Merger and the respective contributions the
     parties would bring to a combined institution;
 
          (v) The expectation that the Merger will provide holders of GNYSB
     Common Stock with the opportunity to receive a substantial premium over the
     historical trading prices for their shares and that a portion of the
     consideration received will be tax-free for federal income tax purposes;
 
          (vi) The review by the GNYSB Board with its legal and financial
     advisors of the provisions of the Merger Agreement and the Stock Option
     Agreement and the limit therein on the total amount AFC could obtain under
     the Stock Option Agreement and the termination fee arrangements of $10
     million;
 
          (vii) The oral presentation by Sandler O'Neill and the oral opinion of
     Sandler O'Neill that the consideration to be received by holders of GNYSB
     Common Stock, including the shares of GNYSB Common Stock issued upon the
     conversion of GNYSB Series A Preferred Stock, and GNYSB Series B Preferred
     Stock is fair to the holders thereof from a financial point of view. See
     "-- Opinions of Financial Advisors -- GNYSB;"
 
          (viii) The similarity between AFC's and GNYSB's views, approaches and
     commitments to the communities and customers they each serve and their
     respective employees;
 
          (ix) The expectation that AFC will continue to provide quality service
     to the communities and customers served by GNYSB; and
 
          (x) AFC's agreement in the Merger Agreement to form an Employee Merger
     Transition Committee that will include Mr. Keegan, Mr. Engelke and such
     others as they shall mutually select and that will have sole responsibility
     for all decisions affecting the employees of GNYSB after the Merger.
 
     The GNYSB Board did not assign any specific or relative weights to the
factors under consideration.
 
     AFC's Reasons for the Merger.  The AFC Board believes that the Merger is in
the best interests of AFC and its stockholders. Accordingly, the AFC Board has
unanimously approved and adopted the Merger Agreement and recommends that AFC
stockholders vote FOR the approval and adoption of the transactions related to
the Merger Agreement.

     In negotiating the terms of the Merger and in considering its
recommendation for the approval of the Merger Agreement, the AFC Board
considered a number of factors including, without limitation, the following:
 
          (i) the Merger Consideration to be paid to the GNYSB stockholders in
     relation to the market value, book value and earnings per share of the
     GNYSB Common Stock;
 
          (ii) the AFC Board's review, based in part on presentations by Merrill
     Lynch, its financial advisor, and management, of the business, operations
     and financial condition of GNYSB, the prospects of the combined
     institution, and the increased market presence, economies of scale, cost
     savings opportunities and enhanced opportunities for growth made possible
     by the Merger;
 
          (iii) the AFC Board's recognition of the complementary nature of the
     markets served and products offered by AFC and GNYSB and expectation that
     the Merger would provide it with opportunities for additional growth, and
     permit it to commence operations with a significant market presence in
     Kings County while further enhancing its market presence in Long Island;
 
          (iv) the impact the Merger is anticipated to have on AFC's
     consolidated results of operations, including anticipated cost savings
     (estimated to be approximately $26.3 million per annum ($13.6 million after
     tax) representing 45% of GNYSB projected 1997 non-interest expense base)
     resulting from consolidation in certain areas such that management of AFC
     estimated that the transaction would be accretive to earnings per share in
     1998 by 4.4%, and accretive to cash earnings per share (calculated as
     reported earnings plus non-cash charges for amortization of goodwill and
     amortization relating to certain employee stock plans) in 1998 by 6.7%,
     with estimated pro forma earnings per share of $3.60 and estimated pro
     forma cash earnings per share of $4.75 for 1998;
 
          (v) the opinion of Merrill Lynch that the Merger Consideration to be
     paid by AFC is fair, from a financial point of view, to AFC. See
     "-- Opinions of Financial Advisors -- AFC");
 
          (vi) the impact of the Merger on depositors, employees, customers and
     communities served by AFC and GNYSB;
 
          (vii) the expectation that the Merger will generally be a tax-free
     transaction to Astoria Financial and its stockholders and that the Merger
     will be accounted for under the purchase method of accounting. See
     "-- Material Federal Income Tax Consequences" and "-- Accounting
     Treatment;"
 
        (viii) the Merger is consistent with AFC's ongoing strategy of growth
     through acquisitions; and
 
          (ix) the terms of the Merger Agreement, the Stock Option Agreement and
     the other documents executed in connection with the Merger.
 
     The AFC Board did not assign any specific or relative weights to the
factors under consideration.
 
OPINIONS OF FINANCIAL ADVISORS
 
     GNYSB.  Pursuant to letter agreements dated as of October 1, 1992 and
February 1, 1994, GNYSB retained Sandler O'Neill as an independent financial
advisor to assist GNYSB in connection with its analysis of various strategic
alternatives available to it, including strategic planning and merger and
acquisition transactions. Pursuant to a letter agreement dated as of March 29,
1997, GNYSB retained Sandler O'Neill as an independent financial advisor in
connection with certain possible business combinations with third parties (the
letter agreements are collectively referred to herein as the "Sandler O'Neill
Agreement.") Sandler O'Neill is a nationally-recognized investment banking firm
whose principal business specialty is banks and savings institutions and, in
that connection, is regularly engaged in the valuation of such businesses and
their securities in connection with mergers and acquisitions and other corporate
transactions.
 
     Pursuant to the terms of the Sandler O'Neill Agreement, Sandler O'Neill
acted as financial advisor to GNYSB in connection with the Merger. In connection
therewith, at the March 29, 1997 meeting at which the GNYSB Board approved and
adopted the Merger Agreement, Sandler O'Neill delivered an oral opinion, which
was subsequently confirmed in writing, to the GNYSB Board, that, as of March 29,
1997, the consideration to be received by the holders of shares of GNYSB Common
Stock (including any shares that are issued upon the conversion of GNYSB Series
A Preferred Stock) and the holders of shares of GNYSB Series B Preferred Stock
pursuant to the Merger Agreement was fair, from a financial point of view, to
such stockholders. Sandler O'Neill has also delivered to the GNYSB Board a
written opinion (the "Sandler
 
                                       38
<PAGE>   46
 
O'Neill Fairness Opinion") dated the date of this Joint Proxy
Statement-Prospectus which is substantially identical to the March 29, 1997
opinion. THE FULL TEXT OF THE SANDLER O'NEILL FAIRNESS OPINION, WHICH SETS FORTH
THE PROCEDURES FOLLOWED, ASSUMPTIONS MADE, MATTERS CONSIDERED AND QUALIFICATIONS
AND LIMITATIONS ON THE REVIEW UNDERTAKEN, IS ATTACHED AS APPENDIX D TO THIS
JOINT PROXY STATEMENT-PROSPECTUS AND IS INCORPORATED HEREIN BY REFERENCE. THE
DESCRIPTION OF SUCH OPINION SET FORTH HEREIN IS QUALIFIED IN ITS ENTIRETY BY
REFERENCE TO APPENDIX D. HOLDERS OF GNYSB COMMON STOCK AND GNYSB SERIES A
PREFERRED STOCK ARE URGED TO READ THE SANDLER O'NEILL FAIRNESS OPINION IN ITS
ENTIRETY IN CONNECTION WITH THEIR CONSIDERATION OF THE PROPOSED MERGER.
 
     THE SANDLER O'NEILL OPINION WAS PROVIDED TO THE GNYSB BOARD FOR ITS
INFORMATION AND IS DIRECTED ONLY TO THE FAIRNESS FROM A FINANCIAL POINT OF VIEW
TO THE HOLDERS OF GNYSB COMMON STOCK (INCLUDING ANY SHARES THAT ARE ISSUED UPON
THE CONVERSION OF GNYSB SERIES A PREFERRED STOCK) AND GNYSB SERIES B PREFERRED
STOCK OF THE PROPOSED MERGER CONSIDERATION. IT DOES NOT ADDRESS THE UNDERLYING
BUSINESS DECISION OF GNYSB TO ENGAGE IN THE MERGER AND DOES NOT CONSTITUTE A
RECOMMENDATION TO ANY GNYSB STOCKHOLDER AS TO HOW SUCH STOCKHOLDER SHOULD VOTE
AT THE GNYSB MEETING WITH RESPECT TO THE MERGER OR ANY OTHER MATTER RELATED
THERETO.
 
     In connection with rendering its opinion dated March 29, 1997, Sandler
O'Neill performed a variety of financial analyses. The following is a summary of
the material analyses performed by Sandler O'Neill and included in Sandler
O'Neill's presentation to the GNYSB Board on March 29, 1997. Such summary does
not purport to be a complete description of Sandler O'Neill's analyses or the
presentation made by Sandler O'Neill to the GNYSB Board. The preparation of a
fairness opinion is a complex process involving subjective judgments and is not
necessarily susceptible to a partial analysis or summary description. Sandler
O'Neill believes that its analyses must be considered as a whole and that
selecting portions of such analyses and the factors considered therein, without
considering all factors and analyses, could create an incomplete view of the
analyses and processes underlying the Sandler O'Neill Fairness Opinion. In
performing its analyses, Sandler O'Neill made numerous assumptions with respect
to industry performance, business and economic conditions and various other
matters, many of which cannot be predicted and are beyond the control of AFC,
GNYSB and Sandler O'Neill. Any estimates contained in Sandler O'Neill's analyses
are not necessarily indicative of future results or values, which may be
significantly more or less favorable than such estimates. Estimates of the
values of companies do not purport to be appraisals or necessarily reflect the
prices at which companies or their securities may actually be sold. Because such
estimates are inherently subject to uncertainty, none of AFC, GNYSB, or Sandler
O'Neill assumes responsibility for their accuracy.
 
     Stock Trading History.  Sandler O'Neill examined the history of the trading
prices and the volume of the GNYSB Common Stock and the AFC Common Stock, and
the relationship between the movements in the prices of the GNYSB Common Stock
and the AFC Common Stock, respectively, to movements in certain stock indices,
including the Standard & Poor's 500 Index, the Nasdaq Banking Index and a
composite group of publicly traded savings institutions in geographic proximity
and of similar asset size.
 
     Analysis of Selected Publicly Traded Companies.  Sandler O'Neill used
publicly available information to compare selected financial and market trading
information, including balance sheet composition, asset quality ratios, loan
loss reserve levels, profitability, capital adequacy, dividends and trading
multiples, of GNYSB, AFC, and two different groups of selected institutions. The
first group consisted of GNYSB, AFC and the following fifteen (15) publicly
traded savings institutions (the "Regional Thrift Group") which operate in the
same general geographic region as GNYSB and have assets of from $1.5 billion to
$18.9 billion: Dime Bancorp, Inc., GreenPoint Financial Corp., Sovereign
Bancorp, Inc., Chevy Chase Bank, FSB, Long Island Bancorp, Inc., RCSB Financial,
Inc., Roslyn Bancorp, Inc., ALBANK Financial Corporation, TR Financial Corp.,
New York Bancorp Inc., Commonwealth Bancorp, Inc., Reliance Bancorp, Inc., ML
Bancorp, Inc., Haven Bancorp, Inc., and JSB Financial, Inc. Sandler O'Neill also
compared GNYSB and AFC to a group of eleven (11) publicly traded savings
institutions of asset size from $3.3 billion to $37.7 billion which had a price
to tangible book value multiple of greater than 140% and a ratio of last 12
months' core income to common equity of greater than 14% (the "Highly-Valued
Group"). The Highly-Valued Group was comprised of: Golden West Financial, Dime
Bancorp, Inc., Charter One Financial, Bank United Corp.,
 
                                       39

ratio for GNYSB was 6.49%, compared to 25.15% for AFC, 26.28% for the Regional
Thrift Group and 24.92% for the Highly-Valued Group. Ratios with respect to AFC
include the one-time SAIF-recapitalization expense.
 
     Analysis of Selected Merger Transactions.  Sandler O'Neill reviewed 128
transactions announced from January 1, 1995 to March 29, 1997 involving public
savings institutions nationwide as targets with transaction values over $15
million ("All Transactions"), 21 transactions announced from January 1, 1995 to
March 29, 1997 involving public savings institutions nationwide with transaction
values between $150 million and $550

million ("Nationwide $150-$550 Transactions"), 10 transactions announced from
January 1, 1995 to March 29, 1997 involving public savings institutions
nationwide with transaction values between $150 million and $550 million and
with the seller's return on average equity below 10% ("Nationwide Low ROAE
$150-$550 Transactions"), 22 transactions announced from January 1, 1995 to
March 29, 1997 involving public savings institutions in the Mid-Atlantic region
with transaction values over $15 million ("Mid-Atlantic Transactions"), 4
transactions announced from January 1, 1995 to March 29, 1997 involving public
savings institutions in the Mid-Atlantic region with transaction values between
$150 million and $550 million ("Mid-Atlantic $150-$550 Transactions"), 1
transaction announced from January 1, 1995 to March 29, 1997 involving a public
savings institution in the Mid-Atlantic region with a transaction value between
$150 million and $550 million and with the seller's return on average equity
below 10% ("Mid-Atlantic Low ROAE $150-$550 Transaction"), 8 transactions
announced from January 1, 1995 to March 29, 1997 involving public savings
institutions in New York ("New York Transactions"), and 2 transactions announced
from January 1, 1995 to March 29, 1997 involving public savings institutions in
New York with transaction values between $150 million and $550 million ("New
York $150-$550 Transactions"). Sandler O'Neill reviewed the ratios of price to
earnings, price to book value, price to tangible book value, price to deposits,
price to assets, and core deposit premium paid in each such transaction and
computed high, low, mean, and median ratios and premiums for the respective
groups of transactions. Based upon the median multiples for All Transactions,
Sandler O'Neill derived an imputed range of values per share of the GNYSB Common
Stock of $13.25 to $26.80. Based upon the median multiples for Nationwide
$150-$550 Transactions, Sandler O'Neill derived an imputed range of values per
share of the GNYSB Common Stock of $12.02 to $24.28. Based upon the median
multiples for Nationwide Low ROAE $150-$550 Transactions, Sandler O'Neill
derived an imputed range of values per share of the GNYSB Common Stock of $13.69
to $24.04. Based upon the median multiples for Mid-Atlantic Transactions,
Sandler O'Neill derived an imputed range of values per share of the GNYSB Common
Stock of $10.70 to $26.26. Based upon the median multiples for Mid-Atlantic
$150-$550 Transactions, Sandler O'Neill derived an imputed range of values per
share of the GNYSB Common Stock of $10.09 to $24.87. Based upon the median
multiples for the one Mid-Atlantic Low ROAE $150-$550 Transaction, Sandler
O'Neill derived an imputed range of values per share of the GNYSB Common Stock
of $13.43 to $24.77. Based upon the median multiples for New York Transactions,
Sandler O'Neill derived an imputed range of values per share of the GNYSB Common
Stock of $11.73 to $29.13. Based upon the median multiples for New York
$150-$550 Transactions, Sandler O'Neill derived an imputed range of values per
share of the GNYSB Common Stock of $10.09 to $24.87.
 
     Discounted Dividend Stream and Terminal Value Analysis.  Sandler O'Neill
also performed an analysis which estimated the future stream of after-tax
dividend flows of GNYSB through the year 2001 under various circumstances,
assuming GNYSB performed in accordance with the earnings forecasts of its
management and certain variations thereof (including variations with respect to
the growth rate of assets, net interest spread, non-interest income,
non-interest expense and dividend payout ratio). To approximate the terminal
value of the GNYSB Common Stock at the end of the five-year period, Sandler
O'Neill applied price to earnings multiples ranging from 8x to 17x and applied
multiples of tangible book value ranging from 100% to 190%. The dividend income
streams and terminal values were then discounted to present values using
different discount rates (ranging from 8% to 13%) chosen to reflect different
assumptions regarding required rates of return of holders or prospective buyers
of the GNYSB Common Stock. This analysis, assuming the current dividend payout
ratio, indicated an imputed range of values per share of the GNYSB Common Stock
of between $6.19 and $15.40 when applying the price to earnings multiples, and
an imputed range of values per share of the GNYSB Common Stock of between $10.43
and $23.96 when applying multiples of tangible book value. In connection with
its analysis, Sandler O'Neill extensively used sensitivity analyses to
illustrate the effects changes in the underlying assumptions would have on the
resulting present value, and discussed these changes with the GNYSB Board.
 
     In addition, Sandler O'Neill performed an analysis which estimated the
future stream of after-tax dividend flows of AFC on a pro forma basis assuming
consummation of the Merger (the "Combined Company") through the year 2001 under
various circumstances, assuming (i) the operations of the Combined Company
attributable to GNYSB performed in accordance with the earnings forecasts of
GNYSB's management and certain variations thereof, as described in the previous
paragraph, (ii) the operations of the
 
                                       41
<PAGE>   49
 
Combined Company attributable to AFC performed in accordance with the earnings
forecasts of AFC's management and certain variations thereof (including
variations with respect to the growth rate of assets, net interest spread,
non-interest income, non-interest expense and dividend payout ratio); and (iii)
the Combined Company realized cost savings equal to 48.8% of GNYSB's projected
non-interest expenses (other than the expense of deposit insurance). To
approximate the terminal value of the AFC Common Stock at the end of the
five-year period, Sandler O'Neill applied a range of price to earnings multiples
and tangible book value multiples. The dividend income streams and terminal
values were then discounted to present values using different discount rates
(ranging from 9% to 14%) chosen to reflect different assumptions regarding
required rates of return of holders or prospective buyers of the AFC Common
Stock. This analysis, assuming the current dividend payout ratio, indicated that
the imputed range of values of the 0.5 shares of AFC Common Stock or $19.00 in
cash to be received in the Merger for each share of GNYSB Common Stock was in
excess of the imputed range of the values of the shares of GNYSB Common Stock.
In connection with its analysis, Sandler O'Neill extensively used sensitivity
analyses to illustrate the effects changes in the underlying assumptions would
have on the resulting present value, and discussed these changes with the GNYSB
Board.
 
     In connection with rendering its opinion of March 29, 1997, Sandler O'Neill
also reviewed, among other things: (i) the Merger Agreement and exhibits
thereto; (ii) the Stock Option Agreement; (iii) AFC's audited consolidated
financial statements and management's discussion and analysis of the financial
condition and results of operations contained in its annual report to
shareholders for the year ended December 31, 1996; (iv) GNYSB's audited
consolidated financial statements and management's discussion and analysis of
the financial condition and results of operations contained in its annual report
to shareholders for the year ended December 31, 1996; (v) certain financial
analyses and forecasts of GNYSB prepared by and reviewed with management of
GNYSB and the views of senior management of GNYSB regarding GNYSB's past and
current business operations, results thereof, financial condition and future
prospects, (vi) certain financial analyses and forecasts of AFC prepared by and
reviewed with management of AFC and the views of senior management of AFC
regarding AFC's past and current business operations, results thereof, financial
condition and future prospects; (vii) the pro forma impact of the Merger on AFC;
(viii) the historical reported price and trading activity for the AFC Common
Stock and the GNYSB Common Stock, including a comparison of certain financial
and stock market information for AFC and GNYSB with similar information for
certain other companies, the securities of which are publicly traded; (ix) the
financial terms of recent business combinations in the savings institution and
banking industries; (x) the current market environment generally and the banking
environment in particular; and (xi) such other information, financial studies,
analyses and investigations and financial, economic and market criteria as
Sandler O'Neill considered relevant. Sandler O'Neill was not asked to, and did
not, solicit indications of interest in a potential transaction with GNYSB from
other third parties, other than one third party specifically identified to
Sandler O'Neill by GNYSB.
 
     In connection with rendering the Sandler O'Neill Fairness Opinion, Sandler
O'Neill confirmed the appropriateness of its reliance on the analyses used to
render its March 29, 1997 opinion by performing procedures to update certain of
such analyses and by reviewing the assumptions upon which such analyses were
based and the factors considered in connection therewith.
 
     In performing its reviews, Sandler O'Neill assumed and relied upon, without
independent verification, the accuracy and completeness of all the financial
information, analyses and other information reviewed by and discussed with it,
and Sandler O'Neill did not make an independent evaluation or appraisal of the
specific assets, the collateral securing assets or the liabilities of AFC or
GNYSB or any of their subsidiaries, or the collectibility of any such assets
(relying, where relevant, on the analyses and estimates of AFC and GNYSB). With
respect to the financial projections reviewed with each company's management,
Sandler O'Neill assumed that they have been reasonably prepared on bases
reflecting the best currently available estimates and judgments of the
respective managements of the respective future financial performances of AFC
and GNYSB and that such performances will be achieved. Sandler O'Neill also
assumed that there has been no material change in AFC's or GNYSB's assets,
financial condition, results of operations, business or prospects since the date
of the last financial statements noted above. With respect to the exchange of
GNYSB Series B Preferred Stock, Sandler O'Neill also assumed that the terms and
conditions of the AFC Series B Preferred Stock are substantially identical to
the GNYSB Series B Preferred Stock and that there are no material and
 
                                       42
<PAGE>   50
 
adverse differences in the rights and privileges of the holders of the AFC
Series B Preferred Stock under Delaware law as compared to the rights and
privileges of holders of the GNYSB Series B Preferred Stock under New York law.
 
     Under the Sandler O'Neill Agreement, GNYSB will pay Sandler O'Neill a
transaction fee in connection with the Merger, a substantial portion of which is
contingent upon the consummation of the Merger. Under the terms of the
Agreement, GNYSB will pay Sandler O'Neill a transaction fee equal to 1.0% of the
aggregate purchase price paid in the transaction (as defined in the Sandler
O'Neill Agreement). Based upon the closing price of AFC Common Stock on the
business day preceding announcement of the Merger, such fee would be
approximately $3.1 million. Approximately 25% of such transaction fee was paid
upon execution of the Merger Agreement and 75% will be paid if the Merger is
consummated. GNYSB has also paid Sandler O'Neill a fee of $100,000 for rendering
the Sandler O'Neill Fairness Opinion. The Sandler O'Neill Agreement provides
that the aggregate of the 1% transaction fee and the fee paid for the Sandler
O'Neill Fairness Opinion will not exceed $3.4 million. GNYSB has also agreed to
reimburse Sandler O'Neill for its reasonable out-of-pocket expenses incurred in
connection with its engagement and to indemnify Sandler O'Neill and its
affiliates and their respective partners, directors, officers, employees,
agents, and controlling persons against certain expenses and liabilities,
including liabilities under securities laws.
 
     Pursuant to the Sandler O'Neill Agreement, Sandler O'Neill has in the past
provided, and may continue to provide, other financial advisory services to
GNYSB and has received, and may receive, fees for the rendering of such
services. In the ordinary course of its business, Sandler O'Neill may actively
trade the debt and/or equity securities of AFC and GNYSB and their respective
affiliates for their own account and for the accounts of customers and,
accordingly, may at any time hold a long or short position in such securities.
 
     AFC.  AFC retained Merrill Lynch to act as its exclusive financial advisor
to assist AFC in analyzing, structuring, negotiating and effecting a transaction
with GNYSB.
 
     Representatives of Merrill Lynch attended the meeting of the AFC Board held
on March 27, 1997 at which the AFC Board considered and approved the Merger
Agreement. At that meeting, Merrill Lynch rendered its oral opinion, that, as of
the date of the Merger Agreement, the Merger Consideration was fair to AFC from
a financial point of view. This opinion was confirmed in writing as of the date
of the Merger Agreement. Such opinion was reconfirmed in writing as of the date
of this Joint Proxy Statement-Prospectus (the "Merrill Lynch Opinion").
 
     The full text of Merrill Lynch's written opinion dated as of the date of
this Joint Proxy Statement-Prospectus is attached as Appendix E to this Joint
Proxy Statement-Prospectus and is incorporated herein by reference. The
description of the Merrill Lynch Opinion set forth herein is qualified in its
entirety by reference to the full text of such opinion. AFC stockholders are
urged to read the opinion in its entirety for a description of the procedures
followed, assumptions made, matters considered, and qualifications and
limitations on the review undertaken, by Merrill Lynch in connection therewith.
 
     THE MERRILL LYNCH OPINION WAS PROVIDED TO THE AFC BOARD FOR ITS INFORMATION
AND IS DIRECTED ONLY TO THE FAIRNESS FROM A FINANCIAL POINT OF VIEW TO AFC OF
THE PROPOSED MERGER CONSIDERATION. IT DOES NOT ADDRESS THE UNDERLYING BUSINESS
DECISION OF AFC TO ENGAGE IN THE MERGER AND DOES NOT CONSTITUTE A RECOMMENDATION
TO ANY AFC STOCKHOLDER AS TO HOW SUCH STOCKHOLDER SHOULD VOTE AT THE AFC MEETING
WITH RESPECT TO THE MERGER OR ANY OTHER MATTER RELATED THERETO.
 
     The summary set forth below does not purport to be a complete description
of the analyses performed by Merrill Lynch underlying the Merrill Lynch Opinion
or the presentation made by Merrill Lynch to the AFC Board. The preparation of a
fairness opinion involves various determinations as to the most appropriate and
relevant methods of financial analysis and the application of these methods to
the particular circumstances and, therefore, such an opinion is not readily
susceptible to a partial analysis or summary description. Accordingly,
notwithstanding the separate factors summarized below, Merrill Lynch believes
that its analyses must be considered as a whole and that selecting portions of
its analyses and factors considered by it, without considering all analyses and
factors, or attempting to ascribe relative weights to some or all such analyses
and factors, could create an incomplete view of the evaluation process
underlying the Merrill Lynch Opinion.
 
                                       43

     In performing its analyses, Merrill Lynch made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of AFC, GNYSB and Merrill
Lynch. The analyses performed by Merrill Lynch are not necessarily indicative of
actual values or actual future results, which may be significantly more or less
favorable than suggested by such analyses. With respect to the comparison of
selected companies analysis and the analysis of selected nationwide thrift
transactions summarized below, no public company utilized as a comparison is
identical to AFC or GNYSB. Accordingly, an analysis of publicly traded
comparable companies and comparable business combinations is not mathematical;
rather it involves complex considerations and judgments concerning the
differences in financial and operating characteristics of the companies and
other factors that could affect the public trading values of the companies
concerned. The analyses do not purport to be appraisals or to reflect the prices
at which AFC or GNYSB might actually be sold or the prices at which any
securities may trade at the present time or at any time in the future. Merrill
Lynch was not asked to consider, and the Merrill Lynch Opinion does not in any
manner address, the price at which shares of common stock of AFC will actually
trade following consummation of the Merger. In addition, as described below, the
Merrill Lynch Opinion and Merrill Lynch's presentation to the AFC Board were
among many factors taken into consideration by the AFC Board in making its
determination to approve the Merger Agreement. Consequently, the Merrill Lynch
analyses described below should not be viewed as determinative of the decision
of the AFC Board or AFC's management with respect to the Merger.
 
     In arriving at its opinion, Merrill Lynch, among other things, reviewed
certain publicly available business and financial information relating to AFC
and GNYSB, as well as a draft of the Merger Agreement. Merrill Lynch also
reviewed certain other information, including financial forecasts for AFC and
GNYSB, as well as information regarding cost savings and related expenses and
revenue enhancements expected to result from the Merger (the "Expected
Synergies") provided to it by AFC and GNYSB, and met with members of senior
management of AFC and GNYSB to discuss the businesses and prospects of AFC and
GNYSB, before and after giving effect to the Merger, and the Expected Synergies.
 
     Merrill Lynch reviewed certain financial and stock market data for AFC and
GNYSB and compared that data with similar data for other publicly held companies
that Merrill Lynch deemed to be relevant. In addition, Merrill Lynch considered
the financial terms of certain other transactions which Merrill Lynch deemed
relevant. Merrill Lynch also considered the pro forma impact of the Merger.
Merrill Lynch reviewed such other financial studies and analyses and performed
such other investigations and took into account such other matters as it deemed
necessary, including its assessment of general economic, market and monetary
conditions.
 
     In preparing its opinion, Merrill Lynch relied on the accuracy and
completeness of all information supplied or otherwise made available to Merrill
Lynch, discussed with or reviewed by or for Merrill Lynch, or publicly
available. Merrill Lynch has not assumed responsibility for independently
verifying such information, has not undertaken an independent evaluation or
appraisal of the assets or liabilities, contingent or otherwise, of AFC or GNYSB
or any of their subsidiaries and was not furnished with any such evaluation or
appraisal. Merrill Lynch is not expert in the evaluation of allowances for loan
losses and has not made an independent evaluation of the adequacy of the
allowance for loan losses of AFC or GNYSB, nor has Merrill Lynch reviewed any
individual credit files relating to AFC or GNYSB and Merrill Lynch has assumed
that the aggregate allowance for loan losses for each of AFC and GNYSB is
adequate to cover such losses and will be adequate on a pro forma basis for the
combined entity, utilizing AFC's ordinary course practice for such allowances.
In addition, Merrill Lynch has not conducted any physical inspection of the
properties or facilities of AFC or GNYSB. With respect to the financial forecast
information, including, without limitation, financial forecasts, evaluations of
contingencies and projections regarding under-performing and non-performing
assets, net charge-offs, adequacy of reserves and future economic conditions,
and the Expected Synergies furnished to or discussed with Merrill Lynch by AFC
and GNYSB, Merrill Lynch assumed that they were reasonably prepared and
reflected the best currently available estimates, allocations and judgment of
AFC's and GNYSB's management as to the expected future financial performance of
AFC or GNYSB, as the case may be, and the Expected Synergies. Merrill Lynch
expressed no opinion as to such financial forecast information or the Expected
Synergies or the assumptions on which they were based. In addition, Merrill
Lynch assumed
 
                                       44
<PAGE>   52
 
that the Merger will be accounted for as a purchase under generally accepted
accounting principles and that it will qualify as a tax-free reorganization for
United States Federal income tax purposes.
 
     The Merrill Lynch Opinion is necessarily based upon market, economic and
other conditions as they existed on, and could be evaluated as of, the date of
such opinion. For purposes of rendering its opinion Merrill Lynch assumed, in
all respects material to its analysis, that the representations and warranties
of each party to the Merger Agreement and all related documents and instruments
(collectively, the "Documents") contained therein are true and correct, that
each party to the Documents will perform all of the covenants and agreements
required to be performed by such party under such Documents and that all
conditions to the consummation of the Merger will be satisfied without waiver
thereof. Merrill Lynch also assumed that in the course of obtaining the
necessary regulatory or other consents or approvals (contractual or otherwise)
for the Merger, no restrictions, including any divestiture requirements or
amendments or modifications, will be imposed that will have a material adverse
effect on the contemplated benefits of the Merger.
 
     The projections furnished to Merrill Lynch and used by it in certain of its
analyses were prepared by the management of AFC and GNYSB in connection with the
Merger and were not prepared with a view towards public disclosure. The
projections were based on numerous variables and assumptions which are
inherently uncertain, including, without limitation, factors related to general
economic and competitive conditions, and accordingly, actual results could vary
significantly from those set forth in such projections.
 
     The following is a summary of the material analyses presented by Merrill
Lynch to the AFC Board on March 27, 1997, in connection with its fairness
opinion.
 
     Transaction Summary.  Merrill Lynch reviewed the terms of the proposed
transaction, including the Merger Consideration and the implied aggregate
transaction value. Based on AFC's closing stock price of $38.75 on March 26,
1997, Merrill Lynch calculated an implied transaction value per share of GNYSB
of $19.00, and an implied total transaction value of approximately $292.9
million. Merrill Lynch also calculated the price to market, price to fully
diluted book value, price to fully diluted tangible book value and price to last
twelve months ("LTM") adjusted fully diluted earnings multiples for GNYSB in the
Merger based on such implied total transaction value. This analysis yielded a
price to market multiple of 1.13x based on GNYSB's closing stock price on March
26, 1997 and a price to market multiple of 1.26x based on GNYSB's average
closing stock price over the 30 trading days prior to March 26, 1997, a price to
fully diluted book value multiple of 1.68x, a price to fully diluted tangible
book value multiple of 1.68x, a price to fully diluted earnings multiple of
24.67x, a price to 1997 earnings multiple (based on information provided by
First Call Earnings Estimates ("First Call")) of 19.00x and a price to 1998
earnings multiple (based on information provided by First Call) of 17.27x. First
Call is a data service that monitors and publishes compilations of earnings
estimates by selected research analysts regarding companies of interest to
institutional investors.
 
     Pro Forma Merger Analysis.  Based on projections provided to Merrill Lynch
by AFC's management, Merrill Lynch analyzed certain pro forma effects of the
Merger. This analysis indicated that the Merger would be accretive to projected
earnings per share of AFC Common Stock in 1998 and thereafter (calculated on
both a GAAP and cash basis). Including an estimated pre-tax charge of $30
million for transaction costs and an additional loan loss reserve to comply
GNYSB's reserve methodology to that of AFC's, this analysis indicated that the
Merger would be dilutive to tangible book value per share. In this analysis,
Merrill Lynch assumed that AFC performed in accordance with the earnings
forecasts and Expected Synergies provided to Merrill Lynch by AFC's management.
 
     Contribution Analysis.  Merrill Lynch reviewed the relative contributions
in terms of various balance sheet items, LTM net income, 1997 estimated income
and 1998 estimated income to be made by AFC and GNYSB to the combined
institution based on data at December 31, 1996. Merrill Lynch analyzed total
assets, total loans, total deposits, common equity, total equity, LTM net
income, 1997 estimated income and 1998 estimated income of the combined
institution as provided by AFC's management. This analysis showed that, while
AFC stockholders would own approximately 79.9% of the outstanding shares of the
combined institution based upon the terms of the Merger Agreement, AFC's implied
contribution (not taking into account the Cash Consideration paid pursuant to
the Merger Agreement) was 74.1% of total assets, 73.5% of total loans,
 
                                       45
<PAGE>   53
 
73.0% of total deposits, 78.9% of common equity, 73.7% of total equity, 82.19%
of LTM income, 82.89% of 1997 estimated income and 80.83% of 1998 estimated
income.
 
     Discounted Dividend Stream Analysis.  Using a discounted dividend stream
analysis, Merrill Lynch estimated the net present value of the future streams of
after tax cash flows that GNYSB could produce ("dividendable net income")
assuming fully phased-in after-tax cost savings of $25.7 million and an
estimated pre-tax charge of $30 million for transaction costs and an additional
loan loss reserve to conform GNYSB's reserve methodology to that of AFC's.
Merrill Lynch assumed that GNYSB performed in accordance with earnings forecasts
provided to Merrill Lynch by AFC's management and that GNYSB's tangible common
equity to tangible asset ratio would be maintained at a minimum 6.0% level.
Merrill Lynch assumed terminal values for the GNYSB common stock at 10.0, 11.0
and 12.0 times GNYSB's, estimated operating income in the year 2003 (defined as
net income before intangible amortization). The dividendable net income streams
and terminal values were then discounted to present values using different
discount rates (ranging from 13% to 14%) chosen to reflect different assumptions
regarding required rates of return of holders or prospective buyers of GNYSB
Common Stock. This discounted dividend stream analysis indicated a reference
range of $18.59 to $22.98 per share for GNYSB Common Stock. As indicated above,
this analysis is not necessarily indicative of actual values or actual future
results and does not purport to reflect the prices at which any securities may
trade at the present or at any time in the future. Merrill Lynch noted that the
discounted dividend stream analysis is a widely used valuation methodology, but
the results of such methodology are highly dependent upon the numerous
assumptions that must be made, including earnings growth rates, dividend payout
rates, terminal values and discount rates.
 
     Analysis of Selected Thrift Acquisition Transactions.  Merrill Lynch
reviewed publicly available information regarding selected nationwide thrift
transactions with a value between $100 million and $400 million which had
occurred in the United States since January 1, 1996 that it deemed to be
relevant (the "Comparable Transactions"). The Comparable Transactions and the
month in which they were announced are: Provident Bankshares Corporation's
proposed acquisition of First Citizens Financial Corporation (March, 1997), CCB
Financial Corporation's proposed acquisition of American Federal Bank (February,
1997), CFX Corporation's proposed acquisition of Portsmouth Bank Shares
(February, 1997), Sovereign Bancorp's proposed acquisition of Bankers Corp.
(February, 1997), Temple-Inland Inc.'s proposed acquisition of California
Financial (December, 1996), Pinnacle Financial Services' acquisition of Indiana
Federal Corporation (November, 1996), Webster Financial Corp.'s acquisition of
DS Bancor (October, 1996), Mutual Savings Bank's proposed acquisition of First
Federal Bancshares of Eau Claire (September, 1996), UST Corp.'s acquisition of
Walden Bancorp (August, 1996), North Fork Bancorporation's acquisition of North
Side Savings (July, 1996), First Union's acquisition of Home Financial
Corporation (June, 1996), First Union's acquisition of Center Financial
Corporation (June, 1996), Peoples Heritage Financial's acquisition of Family
Bancorp (May, 1996), NationsBank Corporation's acquisition of TAC Bancshares
(April, 1996) and Norwest Corp.'s acquisition of Primerit Bank FSB (January,
1996). Merrill Lynch compared the price to market multiple, price to fully
diluted book value, price to fully diluted tangible book value, price to LTM
earnings ratios and the implied deposit premium paid in the Merger to the
corresponding ratios for the Comparable Transactions. This analysis yielded a
range of (i) price to market multiple of 0.97x to 1.63x with a mean of 1.29x and
a median of 1.22 (compared with multiple of 1.13x for GNYSB in the Merger), (ii)
price to fully diluted book value multiples of 0.97x to 2.81x with a mean of
1.71 and a median of 1.72x (compared with a multiple of 1.68x for GNYSB in the
Merger), (iii) price to fully diluted tangible book value multiples of 1.03x to
3.03x with a mean of 1.82x and a median of 1.75x (compared with a multiple of
1.68x for GNYSB in the Merger), (iv) price to fully diluted LTM earnings
multiples of 11.73x to 24.69x with a mean of 17.53x and a median of 16.68x
(compared with a multiple of 24.67x for GNYSB in the merger), and (v) implied
deposit premiums paid of 2.80% to 19.39% with a mean of 8.82% and a median of
7.70% (compared with a premium of 8.14% for GNYSB in the merger). This analysis
yielded an overall imputed reference range per share of GNYSB common stock of
$12.84 to $21.61 based on the mean and median imputed range.
 
     No company or transaction used in the above analysis as a comparison is
identical to GNYSB or the Merger respectively. Accordingly, an analysis of the
results of the foregoing necessarily involves complex
 
                                       46
<PAGE>   54
 
considerations and judgments concerning differences in financial and operating
characteristics of the companies and other factors that could affect the public

     In connection with its opinion dated as of the date of this Joint Proxy
Statement-Prospectus, Merrill Lynch performed procedures to update, as
necessary, certain of the analyses described above and reviewed the assumptions
on which such analyses described above were based and the factors considered in
connection therewith. Merrill Lynch did not perform any analyses in addition to
those described above in updating its March 27, 1997 opinion.
 
     AFC retained Merrill Lynch based upon Merrill Lynch's experience and
expertise. Merrill Lynch is an internationally-recognized investment banking and
advisory firm. Merrill Lynch, as part of its investment banking business, is
continuously engaged in the valuation of businesses and securities in connection
with mergers and acquisitions, negotiated underwritings, competitive biddings,
secondary distributions of listed and unlisted securities, private placements
and valuations for corporate and other purposes. Merrill Lynch has, in the past,
provided financial advisory and/or financing services to AFC and GNYSB and may
continue to do so and has received, and may receive, fees for the rendering of
such services. In the ordinary course of its business, Merrill Lynch and its
affiliates may actively trade the debt and/or equity securities of AFC and GNYSB
and their respective affiliates for their own account and for the accounts of
customers and, accordingly, may at any time hold a long or short position in
such securities.
 
     AFC and Merrill Lynch have entered into a letter agreement dated March 19,
1997 relating to the services to be provided by Merrill Lynch in connection with
the Merger. AFC has agreed to pay Merrill Lynch fees as follows: (i) a cash fee
of $25,000, which was payable upon the execution of the letter agreement, (ii) a
cash fee of $200,000, which was payable upon the execution of the Merger
Agreement and (iii) a cash fee in an amount equal to 0.60% of the aggregate
purchase price paid in connection with the Merger to be calculated at the
closing of the Merger. Based on the closing price of AFC Common Stock on the
business day preceding announcement of the Merger, this fee is estimated to be
approximately $1.8 million (less any fees paid pursuant to clauses (i) or (ii)
above). In such letter, AFC also agreed to reimburse Merrill Lynch for its
reasonable out-of-pocket expenses incurred in connection with its advisory work,
including the reasonable fees and disbursements of its legal counsel, and to
indemnify Merrill Lynch against certain liabilities relating to or arising out
of the Merger, including liabilities under the federal securities laws.
 
PROCEDURES FOR EXCHANGE OF GNYSB COMMON STOCK CERTIFICATES
 
     As of the Effective Time, AFC shall deposit, or will cause to be deposited,
with the Exchange Agent, for the benefit of the holders of shares of GNYSB
Common Stock for exchange, an estimated amount of cash sufficient to pay the
aggregate Cash Consideration and the aggregate amount of cash paid in lieu of
fractional shares, and AFC shall reserve for issuance with its Transfer Agent
and Registrar the aggregate Stock Consideration and AFC Series B Preferred Stock
to be issued.
 
     The Letter of Transmittal and Election Form to be mailed within three
business days after the Effective Date will specify that delivery will be
effected, and risk of loss and title to the GNYSB Stock Certificates
representing AFC Common Stock shall pass, only upon proper delivery of the GNYSB
Stock Certificates to the Exchange Agent and shall include instructions for use
in effecting the surrender of the GNYSB Stock
 
                                       48
<PAGE>   56
 
Certificates in exchange for certificates evidencing shares of AFC Common Stock
or cash or AFC Series B Preferred Stock, as appropriate.
 
     Upon the proper surrender to the Exchange Agent of a GNYSB Stock
Certificate for cancellation, together with such letter of transmittal, duly
executed and completed in accordance with the instructions thereto, and such
other documents as may be reasonably required pursuant to such instructions, the
holder of such GNYSB Stock Certificate will be entitled to receive in exchange
therefor the appropriate Merger Consideration or a certificate representing
shares of AFC Series B Preferred Stock, as appropriate. However, holders of the
GNYSB Series B Preferred Stock Certificates will not be required to exchange
such certificates for certificates representing AFC Series B Preferred Stock,
but may do so voluntarily. As soon as practicable after completion of the
allocations of the Merger Consideration and in no event later than ten business
days after the Election Deadline, the Exchange Agent shall distribute AFC Common
Stock and cash as provided in the Merger Agreement.
 
     No dividends or other distributions declared or made after the Effective
Time with respect to AFC Common Stock with a record date after the Effective
Time shall be paid to the holder of any unsurrendered GNYSB Stock Certificate
with respect to the shares of AFC Common Stock represented thereby, and no cash
payment in lieu of any fractional shares shall be paid to any such holder, until
the holder of such GNYSB Stock Certificate shall surrender such certificate.
Subject to the effect of escheat, tax or other applicable laws, following
surrender of any such Certificate, the holder of whole shares of AFC Common
Stock issued in exchange therefor, will be paid without interest, (i) the amount
of any cash payable with respect to a fractional share of AFC Common Stock to
which such holder is entitled and the amount of dividends or other distributions
with a record date after the Effective Time and theretofore paid with respect to
such whole shares of AFC Common Stock, and (ii) at the appropriate payment date,
the amount of dividends or other distributions, with a record date after the
Effective Time but prior to surrender and a payment date occurring after
surrender, payable with respect to such whole shares of AFC Common Stock.
 
     At the Effective Time, the stock transfer books of GNYSB will be closed and
there shall be no further registration of transfers of shares of GNYSB Common
Stock, GNYSB Series A Preferred Stock or GNYSB Series B Preferred Stock
thereafter on the records of GNYSB. From and after the Effective Time, the
holders of certificates representing shares of GNYSB Common Stock outstanding
immediately prior to the Effective Time shall cease to have any rights with
respect to such shares of GNYSB Common Stock, except as otherwise provided
herein or by law.
 
     Any portion of the aggregate Cash Consideration or the proceeds of any
investments thereof that remains unclaimed by the stockholders of GNYSB for six
(6) months after the Effective Time will be repaid by the Exchange Agent to AFC
upon the written request of AFC. After such request is made, any stockholders of
GNYSB will look only to AFC for payment and issuance of their Merger
Consideration deliverable in respect of each share of GNYSB Common Stock such
stockholder holds as determined pursuant to the Merger Agreement without any
interest thereon. If outstanding certificates for shares of GNYSB Common Stock
are not surrendered or the payment for such shares is not claimed prior to the
date on which such payments would otherwise escheat to or become the property of
any governmental unit or agency, the unclaimed items shall, to the extent
permitted by abandoned property and any other applicable law, become the
property of AFC (and to the extent not in its possession shall be paid over to
it), free and clear of all claims or interest of any person previously entitled
to such claims. Notwithstanding the foregoing, none of AFC, Astoria Federal, the
Exchange Agent or any other person shall be liable to any former holder of GNYSB
Common Stock or GNYSB Series B Preferred Stock for any amount delivered to a
public official pursuant to applicable abandoned property, escheat or similar
laws.
 
     AFC and the Exchange Agent shall be entitled to rely upon GNYSB's stock
transfer books to establish the identity of those persons entitled to receive
the Merger Consideration or shares of AFC Series B Preferred Stock, which books
shall be conclusive with respect thereto. In the event of a dispute with respect
to ownership of stock represented by any GNYSB Stock Certificate, AFC and the
Exchange Agent shall be entitled to deposit any consideration represented
thereby in escrow with an independent third party and thereafter be relieved
with respect to any claims thereto.
 
                                       49
<PAGE>   57
 
     In the event any GNYSB Stock Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
such GNYSB Stock Certificate to be lost, stolen or destroyed and, if required by
the Exchange Agent, the posting by such person of a bond in such amount as the
Exchange Agent may direct as indemnity against any claim that may be made
against it with respect to such GNYSB Stock Certificate, the Exchange Agent will
issue in exchange for such lost, stolen or destroyed GNYSB Stock Certificate the
Merger Consideration or the shares of AFC Series B Preferred Stock deliverable
in respect thereof pursuant to the Merger Agreement.
 
REGULATORY APPROVALS
 
     Pursuant to the Bank Merger Act, Section 1828(c) of Title 12 of the United
States Code, and the Home Owners' Loan Act, Section 1467a(s) of Title 12 of the
United States Code and Sections 552.13 and 563.22 of Title 12 of the Code of
Federal Regulations, promulgated thereunder, the Merger is subject to the
approval of the OTS. AFC filed an application for approval of the Merger with
the OTS on June 5, 1997. This application is currently under review by the OTS.
There can be no assurance as to the timing of such approval or that the OTS will
approve the Merger. The OTS is required to evaluate the applications by taking
into consideration, among other things, the capital level of the resulting
institution, the financial and managerial resources and future prospects of the
institutions involved, the convenience and needs of the communities to be served
and the conformity of the transaction to applicable law, regulation and
supervisory policies. In addition, the OTS may not approve any proposed
acquisition (i) which would result in a monopoly or which would be in
furtherance of any combination or conspiracy to monopolize or to attempt to
monopolize the savings and loan business in any part of the United States, or
(ii) which in any section of the country may have the effect of substantially
lessening competition or tending to create a monopoly or which in any other
manner would be in restraint of trade, unless the OTS finds that the
anti-competitive effects of the proposed acquisition are clearly outweighed in
the public interest by the probable effect of the acquisition in meeting the
convenience and needs of the community to be served. Under the Community
Reinvestment Act of 1977 ("CRA"), the OTS must take into account Astoria
Federal's record of performance in meeting the credit needs of the entire
community, including low- and moderate-income neighborhoods, served by Astoria
Federal. The OTS also considers, among other things, the fairness and disclosure
of the plan (including compensation to officers, directors and controlling
persons of the disappearing association by the surviving association), the
justification, need for and compensation to be paid to any advisory board, fees
paid to each person or firm rendering legal or other professional services in
connection with a merger, and the accounting and tax treatment of the merger.
The regulations of the OTS also provide for the publication of notice and the
opportunity for public comments relating to the application for approval
discussed above.
 
     In addition, under federal law, a period of 30 days must expire following
approval by the OTS within which period the Department of Justice may file
objections to the Merger under the federal antitrust laws. The post-approval
waiting period may be reduced by the OTS to 15 days, with the concurrence of the
Department of Justice. The Department of Justice could take such action under
the antitrust laws as it deems necessary or desirable in the public interest,
including seeking to enjoin the Merger unless divestiture of an acceptable
number of branches to a competitively suitable purchaser could be made. While
AFC believes that the likelihood of such action by the Department of Justice is
remote in this case, there can be no assurance that the Department of Justice
will not initiate such proceeding, or that the Attorney General of the State of
New York will not challenge the Merger, or if such proceeding is instituted or
challenge is made, as to the result thereof.
 
     In addition, pursuant to Section 601 of the NYBL, the Merger is subject to
the prior approval of the Superintendent. AFC filed an application for approval
of the Merger with the Superintendent on June 5, 1997. In determining whether to
approve the application for the merger of GNYSB with and into Astoria Federal,
the Superintendent will consider, among other factors, whether the Merger would
be consistent with adequate or sound banking and would not result in
concentration of assets beyond limits consistent with effective competition, and
whether the Merger would result in such a lessening of competition as to be
injurious to the interest of the public or tend toward monopoly. The
Superintendent will also consider the public interest and the needs and
convenience thereof. Further, it is the policy of the State of New York to
ensure the safe and
 
                                       50
<PAGE>   58
 
sound conduct of banking organizations, to conserve assets of banking
organizations, to prevent hoarding of money, to eliminate unsound and
destructive competition among banking organizations, and to maintain public
confidence in the business of banking and protect the public interest and the
interests of depositors, creditors, and stockholders, and such factors will be
considered by the Superintendent in connection with Astoria Federal's
application.
 
     The Merger cannot proceed in the absence of the requisite regulatory
approvals. See "-- Conditions to the Consummation of the Merger" and
"-- Termination." There can be no assurance that such regulatory approvals will
be obtained, and if obtained, there can be no assurance as to the date of any
such approval. There can also be no assurance that any such approvals will not
contain a condition or requirement which causes such approvals to fail to
satisfy the conditions set forth in the Merger Agreement and described below
under "-- Conditions to the Consummation of the Merger."
 
     Inner City Press/Community on the Move has indicated in a letter to the OTS
that it intends to protest the application to be submitted by AFC to the OTS
with respect to the Merger on the grounds of the institutions' CRA compliance.
AFC and GNYSB believe that any such protest would be without merit although
there can be no assurance that such protest, if filed, would not delay or
otherwise affect AFC's ability to obtain the requisite regulatory approvals of
the Merger. As a result of the most recent OTS examination of Astoria Federal,
Astoria Federal received a CRA compliance rating of "Outstanding." Based upon
the most recent New York State Banking Department and FDIC examinations of
GNYSB, GNYSB received a CRA compliance rating of "Satisfactory."
 
CONDITIONS TO THE CONSUMMATION OF THE MERGER
 
     Consummation of the Merger is subject to various conditions. While it is
anticipated that all such conditions will be satisfied, there can be no
assurance that all of such conditions will be satisfied or waived.
 
     The respective obligations of AFC and GNYSB to cause the Merger to be
consummated are subject to certain conditions, including the following:
 
          (i) the requisite vote of GNYSB's stockholders and AFC's stockholders;
 
          (ii) receipt and effectiveness of all regulatory approvals required to
     consummate the Merger and the expiration of all applicable statutory
     waiting periods in respect thereof; provided, that no regulatory approval

     on (x) GNYSB and its subsidiaries taken as a whole or (y) AFC and its
     subsidiaries taken as a whole;
 
          (iii) no party to the Merger Agreement shall be subject to any order,
     decree or injunction of a court or agency of competent jurisdiction which
     prohibits the consummation of the Merger;
 
          (iv) no statute, rule or regulation shall have been enacted, entered,
     promulgated, interpreted, applied or enforced by any governmental authority
     which prohibits, restricts or makes illegal consummation of the Merger;
 
          (v) no proceedings shall be pending or threatened by the Commission to
     suspend the effectiveness of the Registration Statement; and the shares of
     AFC Common Stock issuable pursuant to the Merger Agreement shall have been
     approved for listing on the Nasdaq National Market, subject to official
     notice of issuance;
 
          (vi) AFC shall have received letters from Messrs. Keegan, Henchy and
     Harris with respect to settlement of such individuals' rights under the
     specified compensation and benefits programs;
 
          (vii) the representations and warranties of the other party in the
     Merger Agreement being true and correct in all material respects as of the
     dates specified therein, and the performance by the other party in all
     material respects of all obligations required by the Merger Agreement to be
     performed;
 
          (viii) the receipt by AFC of the opinion of Thacher Proffitt & Wood,
     and the receipt by GNYSB of the opinion of Sullivan & Cromwell, each
     substantially to the effect that on the basis of the facts, representations
     and assumptions set forth in such opinion which are consistent with the
     state of facts
 
                                       51
<PAGE>   59
 
     existing at the Effective Time, the Merger will be treated for federal
     income tax purposes as a reorganization within the meaning of Section
     368(a) of the Code and that, accordingly, no gain or loss will be
     recognized by AFC or GNYSB as a result of the Merger; and
 
          (ix) the delivery to each of AFC and GNYSB of various letters,
     certificates and other documents.
 
     The obligations of AFC and Astoria Federal to cause the Merger to be
consummated are subject to certain additional conditions, including that neither
AFC nor Astoria Federal shall have become an "Acquiring Person" and no "Stock
Acquisition Date" or "Distribution Date" shall have occurred as such terms are
defined in the GNYSB Rights Agreement, and the rights reserved thereunder shall
not have become distributable, unredeemable or exercisable. See "CERTAIN RELATED
TRANSACTIONS -- Amendment to GNYSB Rights Agreement."
 
     The obligations of GNYSB to cause the Merger to be consummated are subject
to certain additional conditions, including the following:
 
          (i) AFC shall have filed with the Secretary of State of the State of
     Delaware the amendment to the certificate of incorporation changing the par
     value of the shares of AFC Preferred Stock to $1.00 per share and AFC's

     and such documents shall have become effective under the DGCL; and
 
          (ii) no "Share Acquisition Date" or "Distribution Date" as such terms
     are defined in AFC's Rights Agreement shall have occurred, and the rights
     reserved thereunder shall not have become distributable, unredeemable or
     exercisable.
 
REPRESENTATIONS AND WARRANTIES
 
     Each of GNYSB and AFC have made certain representations and warranties to
each other in the Merger Agreement as to, among other things, the authorization,
validity, binding effect and enforceability of the Merger Agreement, various
corporate matters, capital structure, compliance with laws, absence of material
adverse changes, labor matters, employee benefit plans, environmental matters,
asset quality, loan portfolio and allowances for possible loan losses,
investment securities and borrowings, books and records, absence of certain
legal proceedings and regulatory actions and certain fees payable in connection
with the proposed transactions. GNYSB has also made certain representations and
warranties to AFC and Astoria Federal with respect to among other things, its
taxes, its deposits, its material agreements, its insurance, its termination
benefits and certain other matters. AFC has also made representations and
warranties to GNYSB, with respect to the shares of AFC Common Stock and AFC
Series B Preferred Stock to be issued in connection with the Merger and AFC's
access to all funds necessary to consummate the Merger and pay aggregate Merger
Consideration. Virtually all of the representations and warranties of the
parties, the accuracy of which is a condition to the closing of the transactions
contemplated by the Merger Agreement, contain exceptions for any condition,
event, change or occurrence that would not have a material adverse effect on the
business, financial condition or results of operations of the party making such
representation or warranty, and its subsidiaries taken as a whole; provided that
any such effects resulting from any (i) changes in law, rule or regulation or
generally accepted accounting principles or interpretations thereof that applies
to both AFC and Astoria Federal, and GNYSB, as the case may be, or (ii) changes
in interest rates, shall not be considered in determining if a material adverse
effect has occurred. The representations and warranties of the parties do not
survive beyond the Effective Time if the Merger is consummated, and, if the
Merger Agreement is terminated without consummation of the Merger, there will be
no liability on the part of any party for a misrepresentation except that no
party will be relieved from any liability arising out of the willful and
material misrepresentation in the Merger Agreement of any fact actually known to
its senior officers.

during the period from the date of the Merger Agreement to the Effective Time
(except as expressly provided in the Merger Agreement and except to the extent
required by law or regulation or by regulatory authorities), to use
 
                                       52
<PAGE>   60
 
commercially reasonable efforts to, and shall cause each of its respective
subsidiaries to use commercially reasonable efforts to, (i) conduct its business

officers and key employees, (iii) take no action that would materially adversely
affect or delay the ability of AFC, Astoria Federal or GNYSB to perform its
covenants and agreements on a timely basis under the Merger Agreement, (iv) take
no action which would adversely effect or delay the ability of AFC, Astoria

basis under the Merger Agreement or which could reasonably be expected to result
in any such approval, consent or waiver containing any material condition or
restriction, and (v) take no action that results in or is reasonably likely to
have a material adverse effect on the other party.

date of the Merger Agreement to the Effective Time (except as otherwise
specifically provided in the Merger Agreement or as required by law or
regulation or by regulatory authorities), GNYSB has agreed that it shall not,
and shall not permit any of its subsidiaries to, without the prior consent of
AFC, take certain actions, including the following:

     otherwise change its corporate structure or amend GNYSB's or any of its
     subsidiaries' charters or bylaws;

     such employees participating in the increase being granted, immediately
     following such increase and that do not cause the aggregate annual rates of

          (xi) make, renegotiate, renew, increase, extend or purchase any loans,

          (xiv) make any new real estate loans secured by undeveloped land or
     real estate located outside the State of New York or make any construction
     loan; and
 
          (xv) establish or make any commitment relating to the establishment of
     any new branch, other than those for which all regulatory approvals have
     been obtained.
 
     After the date on which all required stockholder approvals, regulatory
approvals and other approvals are received with respect to the Merger and prior
to the Effective Time, at the request of AFC, GNYSB will modify and change its
loan, litigation and real estate valuation policies and practices (including
loan classifications, levels of reserves and tax effects thereof) and investment
and asset/liability management policies and practices so as to be consistent on
a mutually satisfactory basis with those of AFC and generally accepted
accounting principles; provided, that such policies and procedures (i) are
consistent with all applicable laws and regulations and (ii) do not violate any
law or regulation or cause GNYSB to be other than "well-capitalized".
 
     GNYSB is obligated under the Merger Agreement to change the record and
payment dates of its regular quarterly dividend on GNYSB Common Stock to be the
same as record and payment dates of AFC's regular quarterly dividend on AFC
Common Stock. During the period from the date of the Merger Agreement to the
Effective Time, AFC may not, without the prior written consent of the GNYSB,
make, declare or pay any quarterly cash dividends in excess of $0.25 per share
(AFC's current quarterly dividend is $0.15 per share.)
 
NO SOLICITATION
 
     GNYSB has agreed not to: (i) initiate, solicit or encourage, directly or
indirectly, any inquiries or the making of any "Acquisition Proposal" or, (ii)
except to the extent legally required for the discharge by the GNYSB Board of
its fiduciary duties as advised in writing by such board's counsel, engage in
any negotiations concerning, or provide any confidential information or data to,
or have discussions with, any person relating to an Acquisition Proposal, or
otherwise facilitate or attempt to make or implement an Acquisition Proposal.
"Acquisition Proposal" means for such purposes any proposal or offer (including,
without limitation, any proposal or offer to stockholders of GNYSB) with respect
to a merger, consolidation or similar transaction involving, or any purchase of
all or more than 10% of the assets or equity securities of, GNYSB or any of its
material subsidiaries. This restriction applies to GNYSB's officers and
directors as well. GNYSB is required to notify AFC immediately if any such
negotiations or discussions are sought to be initiated or continued in respect
of any such Acquisition Proposal, together with details as to the identity of
the persons making such inquiry or proposal, requesting such information or
seeking such negotiations or discussions and the terms and conditions thereof.
 
AMENDMENT AND WAIVER
 
     Subject to applicable law, the Merger Agreement may be amended by AFC and
GNYSB at any time before or after approval of the matters presented herein in
connection with the Merger by the stockholders of AFC or GNYSB except that,
after any such approval, no amendment may be made which either (i) legally
requires further approval by stockholders, unless such further stockholder
approval is obtained, or (ii) reduces
 
                                       54
<PAGE>   62
 
the aggregate Merger Consideration or contravenes New York State or federal
banking laws, rules or regulations. Subject to applicable law, the parties may
extend the time for performance of the obligations or other acts of the other
party to the Merger Agreement, may waive any inaccuracies in the representations
and warranties contained in the Merger Agreement or in any document delivered
pursuant thereto and may waive compliance with any agreements or conditions for
their respective benefit contained in the Merger Agreement.
 
PRICE-BASED TERMINATION
 
     The Merger Agreement contains a provision that permits GNYSB to terminate
the Merger Agreement if there is a significant and prolonged decline in the per
share market price of AFC's Common Stock that is not coincidental with a
significant and prolonged decline in the stock prices of certain other financial
institution holding companies unless AFC is willing to increase the Merger
Consideration.
 
     This provision specifically provides that GNYSB may terminate the Merger
Agreement at any time during the five-day period commencing with the day (the
"Valuation Date") that is the latest of (i) the day of expiration of the last
waiting period with respect to any of the required regulatory approvals, (ii)
the day on which the last of the required regulatory approvals is obtained and
(iii) the day on which the last of the required stockholder approvals have been
received, such termination to be effective on the 30th day following such date
(the "Effective Termination Date"), if both of the following conditions are
satisfied:
 
          (i) the average of the mean between the closing high bid and the low
     asked prices of a share of AFC Common Stock for the 30 consecutive trading
     days immediately preceding the Valuation Date (the "AFC Market Value") is
     less than $30.30; and
 
          (ii) (A) the number obtained by dividing the AFC Market Value on the
     Valuation Date by $37.88 (the "AFC Ratio") is less than (B) the number
     obtained by dividing the Final Index Price (as defined below) by the
     Initial Index Price (as defined below) and subtracting 0.15 from the
     quotient in this clause (ii)(B) (the "Index Ratio").
 
     If the GNYSB Board elects to exercise this termination right, it must give
prompt written notice to AFC following such election (provided that such notice
of election to terminate may be withdrawn at any time prior to the Effective
Termination Date). During the seven-day period commencing with its receipt of
such notice, AFC has the option to avoid such termination of the Merger
Agreement by electing to increase the consideration to be received by the
holders of GNYSB Common Stock. This increase would occur by adjusting the Stock
Consideration to equal the lesser of (x) a number equal to a fraction, the
numerator of which is $15.15 and the denominator of which is AFC Market Value,
and (y) a number equal to a fraction, the numerator of which is the Index Ratio
(as defined below) multiplied by 0.50 and the denominator of which is the AFC
Ratio. If AFC so elects within such seven-day period, it must give prompt
written notice to GNYSB of such election and the revised Stock Consideration,
whereupon no termination will have occurred and the Merger Agreement will
otherwise remain in effect in accordance with its terms.
 
     The following terms have the meanings indicated below:
 
          "Final Index Price" means the sum of the Final Prices for each company
     comprising the Index Group multiplied by the appropriate weighting.
 
          "Final Price," with respect to any company belonging to the Index
     Group, means the average of the daily closing sales prices of a share of
     common stock of such company, as reported on the consolidated transaction
     reporting system for the market or exchange on which such common stock is
     principally traded, during the period of 30 trading days ending on the
     Valuation Date.
 
          "Index Group" means the 15 financial institution holding companies
     listed below, the common stock of all of which shall be publicly traded and
     as to which there shall not have been a publicly announced proposal at any
     time during the period beginning on the date of the Merger Agreement and
     ending on the Valuation Date for any such company to be acquired. In the
     event that the common stock of any such company ceases to be publicly
     traded or a proposal to acquire any such company is announced at any time
     during the period beginning on the date of this Agreement and ending on the
     Valuation Date, such
 
                                       55
<PAGE>   63
 
     company will be removed from the Index Group, and the weights attributed to
     the remaining companies will be adjusted proportionately for purposes of
     determining the Final Index Price and the Initial Index Price. The 15
     financial institution holding companies and the weights attributed to them
     are as follows:

            TCF Financial Corp.........................................      6.4%
</TABLE>
 
          "Initial Index Price" means the sum of each per share closing price of
     the common stock of each company comprising the Index Group multiplied by
     the applicable weighting, as such prices are reported on the consolidated
     transactions reporting system for the market or exchange on which such
     common stock is principally traded, on the trading day immediately
     preceding the public announcement of the Merger Agreement.
 
If AFC or any company belonging to the Index Group declares or effects a stock
dividend, reclassification, recapitalization, split-up, combination, exchange of
shares or similar transaction between the date of the Merger Agreement and the
Valuation Date, the prices for the common stock of such company will be
appropriately adjusted for purposes of applying the foregoing price-based
termination option.
 
     Prior to making any decision to terminate (or allow the termination of) the
Merger Agreement, each of the GNYSB Board and the AFC Board would consult with
its respective financial and other advisors and would consider all financial and
other information it deemed relevant to its decision. It is not possible to know
whether such termination right will be triggered until after the Valuation Date.
The GNYSB Board has made no decision as to whether it would exercise its right
to terminate the Merger Agreement if the termination right has been triggered.
In considering whether to exercise its termination right in such situation, the
GNYSB Board would, consistent with its fiduciary duties, take into account all
relevant facts and circumstances that exist at such time and would consult with
its financial advisors and legal counsel. Approval of the Merger Agreement by
the stockholders of GNYSB at the GNYSB Meeting will confer on the GNYSB Board
the power, consistent with its fiduciary duties, to elect to consummate the
Merger in the event the termination right is triggered whether or not there is
any increase in the Merger Consideration and without any further action by, or
resolicitation of, the stockholders of GNYSB. If the GNYSB Board elects to
exercise its termination right, GNYSB must give AFC prompt notice of that
decision during a five-day period beginning with the Valuation Date but the
GNYSB Board may withdraw such notice, at its sole option, at any time prior to
the 30th day following the Valuation Date. During the seven-day period
commencing with receipt of such notice, AFC has the option, in its sole
discretion, to increase the Merger Consideration in the manner set forth in the
Merger Agreement and as illustrated above and thereby avoid such termination of
the Merger Agreement. AFC is under no obligation to increase the Merger
Consideration, and there can be no assurance that AFC would elect to increase
the Merger Consideration if the GNYSB Board were to exercise its right to
terminate the Merger Agreement as set forth above. Any such decision would be
made by AFC in consultation with its investment and legal advisors in light of
the circumstances existing at the time AFC has the opportunity to make
 
                                       56
<PAGE>   64
 
such an election. Approval of the issuance of the Merger Shares by the
stockholders of AFC at the AFC Meeting will confer on the AFC Board the power,
consistent with its fiduciary duties, to elect to increase the Merger
Consideration as described above and consummate the Merger in the event the
termination right is triggered without any further action by, or resolicitation
of, the stockholders of AFC. If AFC elects to increase the Merger Consideration
as set forth in the Merger Agreement and as illustrated above, it must give
GNYSB prompt notice of that election and such increased Merger Consideration, in
which case no termination of the Merger Agreement would occur as a result of the
triggering of the termination right.
 
TERMINATION
 
     The Merger Agreement may be terminated at any time prior to the Effective
Time, whether before or after its approval by the stockholders of GNYSB or AFC:
(i) by mutual consent of AFC and GNYSB if the board of directors of each so
determines by a vote of a majority of the members of its entire board; (ii) by
either AFC or GNYSB upon written notice to the other party if either (a) any
approval, consent or waiver of a governmental agency required to permit
consummation of the transactions contemplated by the Merger Agreement shall have
been denied, or (b) if any governmental authority of competent jurisdiction
issues a final, nonappealable order enjoining or otherwise prohibiting the
consummation of the transactions contemplated by the Merger Agreement; (iii) by
either AFC or GNYSB if the board of directors of either so determines by a vote
of a majority of the members of its entire Board, in the event the Merger is not
consummated on or before March 31, 1998, unless the failure to consummate the
Merger by such date is due to the breach of any representation, warranty or
covenant contained in the Merger Agreement by the party seeking to terminate the
Merger Agreement; provided, that such date shall be extended for a period of 30
days following the Valuation Date in the event GNYSB delivers a written notice
to AFC of the satisfaction of the conditions for a price-based termination. See
"-- Price-Based Termination"; (iv) by either AFC or GNYSB, if its board of
directors so determines by vote of a majority of the members of its entire
board, in the event (a) any approval of the stockholders of AFC or GNYSB
required for the consummation of the Merger shall not have been obtained or (b)
of a material breach by the other party of any representation, warranty,
covenant or agreement in the Merger Agreement, which is not cured within 25
business days after written notice of such breach or which breach by its nature
cannot be cured prior to the closing date or any extension thereof; (v) by
either AFC or GNYSB if the GNYSB Board shall have withdrawn or adversely
modified its approval or recommendation of the Merger Agreement at a time when
there has been proposed (x) a merger, consolidation, or similar transaction
involving GNYSB, (y) a purchase, lease or other acquisition of all or
substantially all of the assets of GNYSB or (z) a purchase or other acquisition
(including by way of merger, consolidation, share exchange or otherwise) of
securities representing 20% or more of the voting power of GNYSB; (vi) by either
AFC or GNYSB, if the AFC Board shall have withdrawn or adversely modified its
approval or recommendation of the Merger Agreement or AFC has not convened a
meeting of stockholders at which a vote was taken to approve the transactions
contemplated by the Merger prior to the termination of the Merger Agreement
pursuant to the terms thereof.
 
     In the event of termination of the Merger Agreement, the Merger Agreement
shall thereafter become void and, subject to certain specified provisions of the
Merger Agreement dealing with confidentiality of information and expenses, there
shall be no liability on the part of any party hereto or their respective
officers or directors, except that any such termination shall be without
prejudice to the rights of such party arising out of the willful breach by any
other party of any covenant or willful misrepresentation contained in the Merger
Agreement and except that in certain limited circumstances, a termination fee
may become payable as described under "-- Termination Fees."
 
TERMINATION FEES
 
     In recognition of the efforts and expenses of, and other opportunities
foregone by AFC while, structuring the Merger, the Merger Agreement provides
that GNYSB shall, except as described below, pay to AFC a termination fee of
$5,000,000 in cash (the "Termination Fee") on demand if, during a period of
eighteen (18)
 
                                       57
<PAGE>   65
 
months after the date of the Merger Agreement, the Merger has not been completed
and any of the following has occurred:
 
          (i) Any person other than AFC or an affiliate of AFC acquires
     beneficial ownership of 20% or more of the then outstanding voting power of
     GNYSB;
 
          (ii) GNYSB or any of its subsidiaries, without having received AFC's
     prior written consent, enters into an agreement to engage in an acquisition
     transaction with any person other than AFC or any of its subsidiaries or
     the GNYSB Board recommends that the stockholders of GNYSB approve or accept
     any acquisition transaction with any person other than AFC or any of its
     subsidiaries; under the Merger Agreement, an "acquisition transaction" is
     defined as (a) a merger or consolidation, or similar transaction involving
     GNYSB, (b) a purchase, lease, or other acquisition of all or substantially
     all of the assets of GNYSB or (c) a purchase or other acquisition of
     securities representing 20% or more of the voting power of GNYSB; or
 
          (iii) If a bona fide proposal is made by a third party to GNYSB or its
     stockholders to engage in an acquisition transaction (as defined in
     paragraph (ii) above) and after such proposal is made: (a) GNYSB breaches
     any covenant or obligation contained in the Merger Agreement and such
     breach entitles AFC to terminate the Merger Agreement; (b) the holders of
     GNYSB Common Stock do not approve the Merger Agreement; or (c) the GNYSB
     Board withdraws or modifies in a manner adverse to AFC the recommendation
     of the GNYSB Board with respect to the Merger Agreement.
 
     Notwithstanding the foregoing, GNYSB shall not be obligated to pay to AFC
such termination fee in the event that: (i) GNYSB or AFC validly terminate the
Merger Agreement due to the failure of stockholders of AFC to approve the
transactions contemplated by the Merger, the denial of any governmental approval
necessary to consummate the Merger, the issuance of a final governmental order
enjoining the Merger or the mutual consent of the parties; (ii) GNYSB terminates
the Merger Agreement due to a material breach by AFC of any representation
warranty, covenant or agreement contained in the Merger Agreement which causes
the conditions to the Merger Agreement not to be satisfied and which breach is
not cured within 25 days after written notice of such breach is given by GNYSB
to AFC or which breach is not capable of being cured by the closing or any
extension thereof or due to a drop in the price of the AFC common stock as
described in the Merger Agreement; or (iii) the Merger is not consummated by
March 31, 1998 (other than by reason of GNYSB's fault).
 
     The Termination Fee may be reduced under certain circumstances. Pursuant to
the Stock Option Agreement, GNYSB has granted AFC an option to purchase up to
2,271,536 shares of GNYSB Common Stock at an exercise price of $17.875 upon the
occurrence of certain events. The maximum aggregate profit AFC can receive under
the Stock Option Agreement and the Termination Fee arrangements is $10 million.
See "CERTAIN RELATED TRANSACTIONS -- Stock Option Agreement."
 
     In the event of a termination (i) by either AFC or GNYSB if the GNYSB Board
shall have withdrawn or adversely modified its approval or recommendation of the
Merger Agreement at a time when there has been proposed (x) a merger,
consolidation, or similar transaction involving GNYSB, (y) a lease or other
acquisition of all or substantially all of the assets of GNYSB or (z) a purchase
or other acquisition (including by way of merger, consolidation, share exchange
or otherwise) of securities representing 20% or more of the voting power of
GNYSB; or (ii) by either AFC or GNYSB, if the AFC Board shall have withdrawn or
adversely modified its approval or recommendation of the Merger Agreement or AFC
has not convened a meeting of stockholders at which a vote was taken to approve
the transactions contemplated by the Merger prior to the termination of the
Merger Agreement pursuant to the terms thereof, the party which has withdrawn or
adversely modified its approval or recommendation shall pay to the other party a
termination fee of $5 million in cash in recognition of the efforts, expenses
and other opportunities foregone by the other party while structuring the
Merger. In the event GNYSB makes such payment it shall have no further
obligations to pay the Termination Fee described above.
 
EXPENSES
 
     All costs and expenses incurred in connection with the Merger Agreement,
the Stock Option Agreement and the transactions contemplated thereby shall be
paid by the party incurring such expense.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES
 
     The federal income tax discussion set forth below may not be applicable to
certain classes of taxpayers, including insurance companies, securities dealers,
financial institutions, tax exempt organizations or trusts, foreign persons,
persons who hold shares of GNYSB Common Stock as part of a straddle or
conversion transaction and persons who acquired shares of GNYSB Common Stock
pursuant to the exercise of employee stock options or rights or otherwise as
compensation. In addition, this discussion does not address the tax consequences
of transactions effectuated prior to or after the Merger, whether or not such
transactions are in connection with the Merger, including, without limitation,
the exercise of options or rights to purchase shares of GNYSB stock in
anticipation of the Merger. GNYSB stockholders are urged to consult their own
tax advisors as to the specific tax consequences to them of the Merger,
including the applicability and effect of federal, state, local and other tax
laws.
 
     Tax Opinions.  It is intended that the Merger will be treated as a
reorganization within the meaning of Section 368(a) of the Code. Consummation of
the Merger is conditioned upon receipt by AFC of an opinion of Thacher Proffitt
& Wood, and receipt by GNYSB of an opinion of Sullivan & Cromwell, (the "Tax
Opinions"), dated the Effective Date, substantially to the effect that, for
federal income tax purposes: (i) the Merger will be treated as a reorganization
within the meaning of Section 368(a) of the Code, (ii) no gain or loss will be
recognized by AFC, Astoria Federal or GNYSB as a result of the Merger; (iii)
except to the extent of any cash received in lieu of a fractional share interest
in GNYSB Common Stock or of any Cash Consideration received, no gain or loss
will be recognized by holders of GNYSB Common Stock who exchange their shares of
GNYSB Common Stock for shares of AFC Common Stock pursuant to the Merger; (iv)
the tax basis of the shares of AFC Common Stock received by each holder of GNYSB
Common Stock who exchanges shares of GNYSB Common Stock for shares of AFC Common
stock in the Merger will be the same as the tax basis of the shares of GNYSB
Common Stock surrendered pursuant to the Merger, reduced by any amount allocable
to a fractional share interest of GNYSB Common Stock for which cash is received
and by the amount of any Cash Consideration received, and increased by any gain
recognized on such exchange; (v) the holding period of the shares of AFC Common
Stock received by each holder of GNYSB Common Stock in the Merger will include
the holding period of the shares of GNYSB Common Stock exchanged therefor,
provided that such stockholder holds such shares of GNYSB Common Stock as a
capital asset at the Effective Time; (vi) no gain or loss will be recognized by
the holders of GNYSB Series B Preferred Stock who exchange their shares of GNYSB
Series B Preferred Stock solely for shares of AFC Series B Preferred Stock
pursuant to the Merger; (vii) the tax basis of the shares of AFC Series B
Preferred Stock received by each GNYSB stockholder who exchanges GNYSB Series B
Preferred Stock solely for shares of AFC Series B Preferred Stock in the Merger
will be the same as the tax basis of the GNYSB Series B Preferred Stock
surrendered pursuant to the Merger and (viii) the holding period of the shares
of AFC Series B Preferred Stock received by each holder of GNYSB Series B
Preferred Stock in the Merger will include the holding period of the shares of
GNYSB Series B Preferred Stock exchanged therefor, provided that such
stockholder holds such GNYSB Series B Preferred Stock as a capital asset at the
Effective Time.
 
     The Tax Opinions will not be binding on the Internal Revenue Service (the
"Service"), and there can be no assurance that the Service will not contest the
conclusions expressed therein. The Tax Opinions may be based in part upon
certain factual assumptions and upon certain representations made, and
certificates delivered, by AFC, Astoria Federal, GNYSB and certain of their
respective stockholders, officers and other persons, which representations and
certificates Thacher Proffitt & Wood and Sullivan & Cromwell will assume to be
true, correct and complete. If such representations or certificates are
inaccurate, the Tax Opinions could be adversely affected. In the event the
parties waive receipt of the tax opinions and the material federal income tax
consequences are materially different for stockholders than as described herein,
GNYSB will resolicit its voting stockholders prior to completing the Merger.
 
     Tax Consequences; General.  The following summary sets forth certain
anticipated material federal income tax consequences of the Merger to GNYSB
stockholders. The tax treatment of each GNYSB stockholder will depend in part
upon such stockholder's particular situation and the consideration received by
such stockholder pursuant to the Merger. This summary is based on the provisions
of the Code, the Treasury Regulations promulgated thereunder and administrative
and judicial interpretations thereof, all as in effect as
 
                                       59
<PAGE>   67
 
of the date hereof. Such laws, regulations or interpretations may differ at the
Effective Time, and relevant facts also may differ. In general, the tax
treatment of holders of both GNYSB Common Stock and GNYSB Series B Preferred
Stock who receive Cash Consideration pursuant to the Merger will be essentially
as described below under "Exchange of GNYSB Common Stock for AFC Common Stock
and Cash." Such holders should consult their own tax advisors for the specific
tax consequences applicable to such holders.
 
     Exchange of GNYSB Stock Solely for AFC Stock.  No gain or loss will be
recognized by a GNYSB stockholder who receives solely AFC Common Stock for such
stockholder's shares of GNYSB Common Stock (except to the extent such a
stockholder receives cash in lieu of a fractional share interest in AFC Common
Stock) or by a GNYSB stockholder who receives solely AFC Series B Preferred
Stock for such stockholder's shares of GNYSB Series B Preferred Stock.
 
     Such a GNYSB stockholder's aggregate tax basis in the AFC Common Stock
received pursuant to the Merger will equal such stockholder's aggregate tax
basis in the shares of GNYSB Common Stock exchanged therefor, reduced by any
amount allocable to a fractional share interest of AFC Common Stock for which
cash is received. Such a GNYSB stockholder's aggregate tax basis in the AFC
Series B Preferred Stock received pursuant to the Merger will equal such
stockholder's aggregate tax basis in the shares of GNYSB Series B Preferred
Stock exchanged therefor. The holding period of AFC Common Stock or AFC Series B
Preferred Stock received will include the holding period of the shares of GNYSB
Common Stock or GNYSB Series B Preferred Stock exchanged therefor, provided that
such shares were held as a capital asset as of the Effective Date. GNYSB
stockholders should consult their own tax advisors concerning the determination
of their basis and holding period in any particular share of AFC Common Stock or
AFC Series B Preferred Stock since several methods of determination may be
available.
 
     Exchange of GNYSB Common Stock for AFC Common Stock and Cash.  A GNYSB
stockholder who receives both AFC Common Stock and cash (other than cash
received in lieu of a fractional share interest in AFC Common Stock) will
recognize gain, but not loss, to the extent of the lesser of:
 
          (i) the excess of (A) the sum of the aggregate fair market value of
     the AFC Common Stock received (including the fair market value of any
     fractional share interest in AFC Common Stock for which cash is received)
     and the amount of cash received (other than cash received in lieu of such
     fractional share interest) over (B) the stockholder's aggregate adjusted
     federal income tax basis for the shares of GNYSB Common Stock exchanged;
     and
 
          (ii) the amount of cash received by such stockholder (other than cash
     received in lieu of such fractional share interest).
 
     If the shares of GNYSB Common Stock exchanged in the Merger were held as
capital assets at the Effective Time, any such gain will be treated as capital
gain (which will be long-term capital gain if the shares of GNYSB Common Stock
exchanged were held for more than one year), unless the receipt of cash (other
than cash received in lieu of a fractional share interest) has the effect of a
distribution of a dividend within the meaning of Section 356(a)(2) of the Code,
in which case such gain will be treated as a dividend to the extent of such
stockholder's ratable share of the undistributed accumulated earnings and
profits of GNYSB or possibly of AFC. Following is a brief discussion of such
potential tax treatment; however, GNYSB stockholders should consult their own
tax advisors as to the possibility that all or a portion of any cash received in
exchange for their GNYSB Common Stock will be treated as a dividend.
 
     The stock redemption provisions of Section 302 of the Code apply in
determining whether cash received by a GNYSB stockholder pursuant to the Merger
has the effect of a distribution of a dividend under Section 356(a)(2) of the
Code (the "Hypothetical Redemption Analysis"). Under the Hypothetical Redemption
Analysis, a GNYSB stockholder will be treated as if the portion of the shares of
GNYSB Common Stock exchanged for cash in the Merger had been instead exchanged
for shares of AFC Common Stock (the "Hypothetical Shares"), followed immediately
by a redemption of the Hypothetical Shares by AFC for cash. Under the principles
of Section 302 of the Code, a GNYSB stockholder will recognize capital gain
rather than dividend income with respect to the cash received if the
hypothetical redemption is "not essentially equivalent to a dividend" or is
"substantially disproportionate" with respect to such GNYSB
 
                                       60
<PAGE>   68
 
stockholder. In applying the principles of Section 302, the constructive
ownership rules of Section 318 of the Code will apply in comparing a GNYSB
stockholder's ownership interest in AFC both immediately after the Merger (but
before the hypothetical redemption) and after the hypothetical redemption.
 
     Whether the hypothetical redemption by AFC of the Hypothetical Shares for
cash is "not essentially equivalent to a dividend" with respect to a GNYSB
stockholder will depend upon such stockholder's particular circumstances.
However, the hypothetical redemption must, in any event, result in a "meaningful
reduction" in such GNYSB stockholder's percentage ownership of AFC stock. In
determining whether the hypothetical redemption by AFC results in a meaningful
reduction in a GNYSB stockholder's percentage ownership of AFC stock, and
therefore, does not have the effect of a distribution of a dividend, a GNYSB
stockholder should compare his or her share interest in AFC (including interests
owned actually, hypothetically and constructively) immediately after the Merger
(but before the hypothetical redemption) to his or her share interest after the
hypothetical redemption. The Service has indicated, in Revenue Ruling 76-385,
that a stockholder in a publicly-held corporation whose relative stock interest
in the corporation is minimal and who exercises no "control" over corporate
affairs is generally treated as having had a meaningful reduction in his or her
stock after a redemption transaction if his or her percentage stock ownership in
the corporation has been reduced to any extent, taking into account the
stockholder's actual and constructive ownership before and after the redemption.
In Revenue Ruling 76-385, a reduction from .0001118 percent to .0001081 percent
was found to be a meaningful reduction in stockholdings.
 
     The hypothetical redemption transaction would be "substantially
disproportionate", and therefore, would not have the effect of a distribution of
a dividend with respect to a GNYSB stockholder who owns less than 50% of the
voting power of the outstanding AFC Common Stock if the percentage of AFC Common
Stock actually and constructively owned by such stockholder immediately after
the hypothetical redemption is less than 80% of the percentage of AFC Common
Stock actually, hypothetically and constructively owned by the GNYSB stockholder
immediately before the hypothetical redemption.
 
     In determining how many shares of AFC Common Stock a GNYSB stockholder owns
constructively before the hypothetical redemption for purposes of making the
"not essentially equivalent to a dividend" or "substantially disproportionate"
determination, a GNYSB stockholder must take into account any Hypothetical
Shares owned by the persons or entities whose stock he or she is deemed to own
constructively under Section 318 of the Code.
 
     Such a GNYSB stockholder's aggregate tax basis in the AFC Common Stock
received pursuant to the Merger will equal such stockholder's aggregate tax
basis in the shares of GNYSB Common Stock exchanged therefor, reduced by any
amount allocable to a fractional share interest of AFC Common Stock for which
cash is received and by the amount of any Cash Consideration received, and
increased by the amount of gain, if any, recognized by such stockholder in the
Merger (including any portion of such gain that is treated as a dividend). The
holding period of AFC Common Stock received will include the holding period of
the shares of GNYSB Common Stock exchanged therefor, provided that such shares
of GNYSB Common Stock were held as a capital asset as of the Effective Date.
GNYSB stockholders should consult their own tax advisors concerning the
determination of their basis and holding period in any particular share of AFC
Common Stock since several methods of determination may be available.
 
     Exchange of GNYSB Common Stock Solely for Cash.  A GNYSB stockholder who
receives solely cash in exchange for such stockholder's shares of GNYSB Common
Stock may be treated as (i) having sold such shares of GNYSB Common Stock to
AFC, (ii) having received, in exchange for such shares of GNYSB Common Stock,
stock of AFC which was deemed to have been redeemed by AFC, or (iii) as having
such shares of GNYSB Common Stock deemed to have been redeemed by GNYSB. In the
event of sale treatment, such stockholder would recognize gain or loss in an
amount equal to the difference between the amount of cash received and the
stockholder's aggregate adjusted federal income tax basis for such shares of
GNYSB Common Stock. In the event of redemption treatment, such deemed redemption
would be subject to Section 302 of the Code, with the result that such
stockholder would be treated as having sold his or her shares and would
recognize gain or loss in a like amount if the deemed redemption is in "complete
redemption" of all of such stockholder's stock in the redeeming corporation, is
"substantially disproportionate" with respect to
 
                                       61
<PAGE>   69
 
such stockholder or is "not essentially equivalent to a dividend." In making
such a determination under Section 302, the constructive ownership rules of
Section 318 of the Code will apply in comparing a GNYSB stockholder's ownership
interest in the redeeming corporation both immediately before and after the
Merger. See "-- Exchange of GNYSB Common Stock for AFC Common Stock and Cash."
Gain or loss realized on a sale of such shares of GNYSB Common Stock will be
capital gain or loss if such shares of GNYSB Common Stock were held as capital
assets at the Effective Time, and will be long-term capital gain or loss if such
shares of GNYSB Common Stock were held for more than one year. If sale treatment
does not apply to a deemed redemption, the cash received by such a stockholder
will be treated as a dividend to the extent of the redeeming corporation's
accumulated and current earnings and profits. GNYSB stockholders should consult
their own tax advisors as to the possibility that all or a portion of any cash
received in exchange for their shares of GNYSB Common Stock will be treated as a
dividend.
 
     Fractional Shares of AFC Common Stock.  No fractional shares of AFC Common
Stock will be issued in the Merger. A GNYSB stockholder who receives cash in
lieu of such a fractional share will be treated as having received such
fractional share pursuant to the Merger and then as having exchanged such
fractional share for cash in a redemption by AFC subject to Section 302 of the
Code. Such a deemed redemption will be treated as a sale of the fractional
share, provided that it is not "essentially equivalent to a dividend." See
"-- Exchange of GNYSB Common Stock for AFC Common Stock and Cash." If the AFC
Common Stock represents a capital asset in the hands of the stockholder, the
stockholder will generally recognize capital gain or loss on such a deemed
redemption of the fractional share in an amount determined by the excess of the
amount of cash received therefor and the stockholder's tax basis in the
fractional share. Any such capital gain will be long-term if the GNYSB Common
Stock exchanged was held for more than one year.
 
     Backup Withholding.  Unless an exemption applies under applicable law and
regulations, the Exchange Agent will be required to withhold 31% of any cash
payments to which a non-corporate stockholder or other payee is entitled
pursuant to the Merger unless the stockholder or other payee provides its
taxpayer identification number (social security number, employer identification
number or individual taxpayer identification number) and certifies that such
number is correct. Each stockholder and, if applicable, each other payee must
complete and sign the substitute Form W-9 or, if applicable, the certificate of
foreign status on Form W-8, included with the Election Forms, so as to provide
the information and certification necessary to avoid backup withholding, unless
an applicable exemption exists and is established in a manner satisfactory to
AFC and the Exchange Agent.
 
     Redemption of GNYSB Rights.  Receipt of a cash payment from GNYSB in
redemption of a GNYSB Right should be treated as a dividend taxable as ordinary
income to the extent of the accumulated and current earnings and profits of
GNYSB.
 
ACCOUNTING TREATMENT
 
     AFC will record the Merger using the purchase method of accounting. Under
the purchase method of accounting, assets acquired and liabilities assumed are
recorded at their fair value.
 
DISSENTERS' RIGHTS
 
     GNYSB.  Any holder of GNYSB Common Stock or GNYSB Series A Preferred Stock
entitled to vote on the Merger who does not vote in favor thereof has the right
to receive payment of the fair value of such stockholder's shares of GNYSB
Common Stock, upon compliance with the provisions of Section 6022 of the NYBL.
GNYSB expects that the shares of GNYSB Series A Preferred Stock will have been
converted or redeemed prior to the time at which a notice of election to dissent
may be filed under Section 6022 of the NYBL, in which case holders of GNYSB
Series A Preferred Stock who dissent from the Merger will have dissenters'
rights only with respect to the shares of GNYSB Common Stock into which such
holders' GNYSB Series A Preferred Stock is converted. If shares of GNYSB Series
A Preferred Stock are outstanding at the time a notice of election to dissent is
filed with respect thereto, and all other provisions of Sections 6022 of the
NYBL are complied with, then the holder of GNYSB Series A Preferred Stock who
filed such notice of election to dissent shall have the right to receive payment
of the fair value of such stockholder's shares of GNYSB Series A Preferred
Stock. Failure to comply strictly with the procedures set forth in that section
will cause the stockholder to lose his dissenters' rights. The following summary
of the applicable provisions of
 
                                       62
<PAGE>   70
 
Section 6022 of the NYBL is not intended to be a complete statement thereof and
is qualified in its entirety by reference to the full text of Section 6022 of
the NYBL, which is attached hereto as Appendix F.
 
     Any GNYSB stockholder intending to enforce his right to receive payment for
shares of GNYSB Common Stock or GNYSB Series A Preferred Stock may not vote in
favor of the Merger Agreement and must file with GNYSB before or at the GNYSB
Meeting (but before the stockholders' vote), written objection to the Merger
Agreement. Neither a vote against the Merger Agreement, a proxy directing such
vote, an abstention nor a failure to vote will satisfy the requirement that a
written demand for payment be delivered to GNYSB before the vote on the Merger
Agreement is taken at the GNYSB Meeting. In addition, a vote in favor of the
Merger Agreement shall constitute a waiver of any dissenters' rights pursuant to
the NYBL. A vote against, an abstention or a failure to vote will not constitute
a waiver of such rights.
 
     A stockholder's objection must state that the stockholder intends to demand
payment for his shares of GNYSB Common Stock or GNYSB Series A Preferred Stock,
if the Merger is consummated. Each stockholder who has filed such an objection
will be notified of the approval of the Merger Agreement within ten (10) days
following the date of any approval by the GNYSB stockholders. Any such
stockholder who elects to dissent must, within twenty (20) days of the giving of
such notice, file with GNYSB a written notice of such election containing the
information required under Section 6022 of the NYBL, and simultaneously or
within one month thereafter, must submit the certificate representing shares of
GNYSB Common Stock or GNYSB Series A Preferred Stock for placement of the
appropriate legend thereon. A stockholder may not dissent as to less than all of
the shares of GNYSB Common Stock or GNYSB Series A Preferred Stock held by the
stockholder. A nominee or fiduciary may not dissent on behalf of any beneficial
owner as to less than all of the shares of such owner held of record by such
nominee or fiduciary.
 
     Upon filing a Notice of Election to dissent, a stockholder will cease to
have any of the rights of a stockholder of GNYSB Common Stock or GNYSB Series A
Preferred Stock including dividend rights, except the right to be paid the fair
value of his or her shares and such other rights as are granted under the NYBL.
Withdrawal of any election to dissent will require the written consent of GNYSB.
If the Merger is not consummated, dissenting stockholders will have no right to
payment for shares and will be reinstated with all rights of a stockholder of
GNYSB Common Stock or GNYSB Series A Preferred Stock.
 
     Within seven (7) days after the later of the expiration of the period
within which stockholders may file their written election to dissent or the
consummation of the Merger, AFC may make a written offer to all dissenting
stockholders to pay a specified amount, which it considers to be a fair amount,
for each share of GNYSB Common Stock or GNYSB Series A Preferred Stock held by
dissenting stockholders. If, within thirty (30) days of such offer, any
dissenting stockholder and AFC agree on the price to be paid for the
stockholder's shares of GNYSB Common Stock or GNYSB Series A Preferred Stock the
agreed upon payment will be made to such stockholder within sixty (60) days of
the written offer and upon surrender of the certificates representing such
shares.
 
     If a written offer is not made within the specified period or if there is
no agreement with the dissenting stockholder on the price to be paid, then AFC
may institute a special court proceeding to determine the rights of dissenting
stockholders and to fix the fair value of shares of GNYSB Common Stock or GNYSB
Series A Preferred Stock. If such proceeding is not instituted, then any
dissenting stockholder who has not accepted an offer must initiate a similar
court proceeding within thirty (30) days of the last date on which AFC could
have initiated such a court proceeding. If the required court proceeding is not
instituted within the thirty (30) day period, a dissenting stockholder shall
lose all dissenters' rights unless the court directs otherwise.
 
     AFC.  Under the DGCL stockholders of AFC are not entitled to dissenters'
rights in connection with the transactions related to the consummation of the
Merger.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     Certain members of GNYSB's management and the GNYSB Board may be deemed to
have interests in the Merger in addition to their interests, if any, as holders
of GNYSB Common Stock and as holders of GNYSB Series A Preferred Stock through
their participation in the GNYSB ESOP. The GNYSB Board was aware of these
factors and considered them, among other matters, in approving the Merger
Agreement and the transactions contemplated thereby.
 
                                       63

     Election to Advisory Board.  Promptly following the Effective Time, AFC
will cause all of the non-officer members of the GNYSB Board as of March 29,
1997 who are willing to so serve to be elected or appointed as members of the
Advisory Board, the principal function of which shall be to advise AFC with
respect to deposit and lending activities in GNYSB's former market area and to
maintain and develop customer relationships. The members of the Advisory Board
who are willing to so serve shall be elected to serve a term of three years
beginning on the Effective Date. Each member of the Advisory Board who is not a
director of AFC and who is not an employee of AFC will receive an annual
retainer fee for such service at an annual rate of $24,000, payable in monthly
installments or in one lump sum at any time in advance at the option of AFC. In
addition, within 30 days after the Effective Date, each member of the Advisory
Board will be granted an option to purchase 4,000 shares of AFC Common Stock.
Such options will be for a term of ten (10) years beginning on the Effective
Date and will be exercisable at any time after the Effective Date at an exercise
price per share equal to the closing sales price for a share of AFC Common Stock
on the date of grant.
 
     Effect on Retirement Plan for Non-employee Directors.  GNYSB maintains The
Retirement Plan of The Greater New York Savings Bank for Non-Employee Directors
("GNYSB Directors Plan"). The GNYSB Directors Plan provides each nonemployee
director of GNYSB who has attained age 55 and has completed five years of
service as a director with an annual retirement benefit equal to the director's
annual retainer payable on the date of retirement ($24,000), reduced by 5% for
each year (or fraction thereof) that the director's retirement date precedes the
director's attainment of age 65 and increased to the actuarial equivalent of the
normal annual retirement benefit based upon interest rate and mortality
assumptions specified in the GNYSB Directors' Plan if the director's retirement
date is after age 65. In addition, each non-employee director may elect to
receive the actuarial equivalent of the annual pension benefit described above
in the form of a lump sum payment. All of the directors of GNYSB, other than
Gwendolyn Calvert Baker, will have satisfied the vesting requirements of the
GNYSB Directors Plan at, or prior to, the Effective Time. All of the directors
except for Peter Haeffner, Jr. and C. Stephen Connolly are at least 65 years of
age and are therefore currently eligible for an unreduced retirement benefit.
The Merger, as a "change in control" as defined in the GNYSB Directors Plan will
result in Dr. Baker's benefit being vested and Mr. Connolly, Mr. Haeffner and
Dr. Baker being entitled to an unreduced retirement benefit.
 
     Indemnification.  AFC has agreed, among other things, that AFC shall, from
and after the Effective Time through the sixth anniversary of the Effective
Time, indemnify and hold harmless each present and former director and officer
of GNYSB or its subsidiaries and each officer or employee of GNYSB or its
subsidiaries that is serving or has served as a director or trustee of another
entity expressly at GNYSB's request or direction (each, an "Indemnified Party"),
against any costs or expenses (including reasonable attorneys' fees), judgments,
fines, losses, claims, damages or liabilities (collectively, "Costs") incurred
in connection with any claim, action, suit, proceeding or investigation, whether
civil, criminal, administrative or investigative, arising out of matters
existing or occurring at or prior to the Effective Time (including the
transactions contemplated by the Merger), whether asserted or claimed prior to,
at or after the Effective Time, and to advance any such Costs to each
Indemnified Party as they are from time to time incurred, in each case to the
fullest extent then permitted under applicable law. AFC has also agreed, among
other things, that for a period of six years after the Effective Time, it will
maintain in effect the current policies of directors' and officers' liability
insurance maintained by GNYSB (provided that AFC may substitute therefor
policies with reputable and financially sound carriers of at least the same
coverage and amount containing terms which are no less advantageous to the
beneficiaries thereof); however, in no event will AFC be obligated to expend any
premium per annum in excess of 200% of the amount of the annual premiums paid as
of March 29, 1997 by GNYSB for such insurance.
 
     Employment Agreements for Executive Officers.  AFC has agreed to honor all
existing GNYSB employment, severance and other compensation agreements and
arrangements, including the employment agreements dated various dates (and for
some individuals, subsequent amendatory agreements dated June 22, 1994 amending
the respective employment agreements) between GNYSB and, respectively, Gerard C.
Keegan, Michael J. Henchy, Daniel J. Harris, Philip A. Cimino, Philip T. Spies,
Michael R. Barrett, Franklyn A. Berkowitz, Robert P. Carlson, Gary P. DiLorenzo,
Michael D. Gornicki, Jeanne M. Lutfy, Theodore A. Zarembo and John A. Dresch
(the "Employment Agreements") and change in control letter agreements dated
various dates between GNYSB and, respectively, Gerard C. Keegan, Michael J.
Henchy, Daniel J. Harris, Philip A. Cimino, Philip T. Spies, Michael R. Barrett,
Franklyn A. Berkowitz, Robert P. Carlson,
 
                                       64
<PAGE>   72
 
Gary P. DiLorenzo, Michael D. Gornicki, Jeanne M. Lutfy, Theodore A. Zarembo and
John A. Dresch (the "Change in Control Letter Agreements"). Under the Change in
Control Letter Agreements, upon the involuntary termination of the covered
executive's employment other than for "cause" or the voluntary termination by
the covered executive for "good reason" (as defined in the Change in Control
Letter Agreements) following a "change in control" as defined in those
agreements (which includes the Merger), during the term of such agreements or
within two years after the change in control, if later, the covered executive
would be entitled to the following payments and benefits: (a) the product of (i)
and (ii), where (i) is the sum of the executive's base salary and the single
highest bonus amount paid to him or her during the prior three years and (ii) is
three in the case of Mr. Keegan or two in the case of the twelve other officers;
(b) the present value of the executive's accrued benefit under any of GNYSB's
qualified or non-qualified defined benefit plans and the executive's account
balance under any of GNYSB's qualified or non-qualified defined contribution
plans, in either case to the extent that such accrued benefit or account balance
is not fully vested as of the Effective Date; (c) a lump sum payment for all
outstanding options (whether or not vested) held by the executive equal to the
difference between the exercise price of such options and the higher of the
closing price of the GNYSB Common Stock on the day before the payment or the
highest price per share paid in connection with any change in control of GNYSB
multiplied by the number of shares of GNYSB Common Stock subject to such options
(see "-- Stock Options" below); (d) indemnification for any excise taxes that
may be imposed pursuant to Section 4999 of the Code (the "Excise Tax Indemnity")
and (e) if the Executive has attained age 55 and is eligible for early
retirement under the GNYSB pension plan, a lump sum payment representing the
present value of the difference between normal retirement benefits and early
retirement benefits under the GNYSB pension plan. Each covered executive would
also be entitled to continued insurance coverage for two years.
 
     Under the Employment Agreements upon the involuntary termination of the
executive's employment other than for "cause" (as defined in such agreements) or
a termination by the executive following a material breach of the agreement by
GNYSB, each executive would be entitled to the following payments and
benefits: (a) an amount equal to the executive's annual base salary in effect as
of the date of his termination multiplied by the number of years (including
fractions) remaining in the executive's term under the Employment Agreement,
such amount payable in bi-weekly payments over such term; (b) continued
insurance benefits for the remaining term of such agreement; (c) lump sum cash
payments equal to the present value of the additional benefits to which he would
have been entitled under GNYSB's pension plan, the GNYSB ESOP and GNYSB's
supplemental executive retirement plan ("SERP") or other similar plans if he had
continued working for GNYSB for the remaining term under his agreement; and (d)
a lump sum as payment for all outstanding options held by the executive (whether
or not vested) equal to the difference between the exercise price of such
options and the fair market value of the Common Stock on the date of the
termination multiplied by the number of shares of GNYSB Common Stock subject to
such options. See "-- Stock Options" below. Each Employment Agreement provides
an offset for benefits payable under the related Change in Control Letter
Agreement.
 
     The Merger Agreement provides that Astoria Federal will pay Messrs. Keegan,
Harris and Henchy a cash amount in settlement of their Employment Agreements and
Change in Control Letter Agreements as soon as practicable following the
Effective Time. The estimated maximum severance benefits and excise tax
indemnity payment amount under the Employment Agreements and the Change in
Control Letter Agreements for the executive officers of GNYSB are as follows:
Gerard C. Keegan, $5,253,000 and $1,977,000; Michael J. Henchy, $1,352,000 and
$535,000; Daniel J. Harris, $846,000 and $408,000; Philip A. Cimino, $792,000
and $398,000; Philip T. Spies, $618,000 and $274,000; and all executive officers
as a group, which consists of 13 persons, $12,956,000 and $5,622,000.
 
     Mr. Keegan will be named as a director, Vice Chairman and Chief
Administrative Officer of each of AFC and Astoria Federal. AFC also agrees to
cause one other member of the GNYSB Board (as of March 29, 1997), selected by
GNYSB and acceptable to AFC, to be elected or appointed as a director of AFC and
Astoria Federal as promptly as practicable after the Effective Time. AFC and
Astoria Federal have entered into new employment agreements with Mr. Keegan to
serve as Vice Chairman and Chief Administrative Officer and as a director of AFC
and Astoria Federal, which agreements are conditioned upon the consummation of
the Merger and will take effect at the Effective Time and will have an initial
term of three years. On each anniversary of the Effective Time, the
disinterested members of the Astoria Federal Board may
 
                                       65
<PAGE>   73
 
extend Mr. Keegan's agreement with Astoria Federal for an additional year such
that the remaining term shall be three years. The agreement with AFC
automatically extends daily, so as to maintain its original term of three years,
unless written notice of non-renewal is given by the AFC Board. The agreements
provide for an annual base salary of $350,000. The agreement with AFC provides
for an award of 15,000 shares of restricted stock under the Astoria Federal
Savings and Loan Association Recognition and Retention Plan for Officers and
Employees, with such shares vesting in equal portions over three years beginning
on January 10, 1998. There is no cost to Mr. Keegan for such shares. The
agreements provide for Mr. Keegan's participation in retirement plans, group
life, medical and disability insurance plans and any other employee benefit
programs, including incentive compensation plans and stock option, stock
appreciation right ("SAR") and restricted stock plans maintained by AFC or
Astoria Federal in accordance with the terms and conditions of such plans. The
agreements provide for termination of Mr. Keegan's employment at any time by AFC
or Astoria Federal with or without cause, as separately defined in such
agreements. In the event Mr. Keegan's employment terminates (A) due to AFC's or
Astoria Federal's (i) failure to re-elect him to the office of Vice Chairman and
Chief Administrative Officer (or a higher office) or to the Board, (ii) failure
by whatever cause to vest in Mr. Keegan the functions, duties or
responsibilities prescribed in the agreement, (iii) material breach of the
agreements or reduction in Mr. Keegan's base salary or other change to the terms
and conditions of his compensation and benefits which either individually or in
the aggregate has a material adverse effect on the aggregate value of the total
compensation package provided to him or (iv) relocation of Mr. Keegan's
principal place of employment outside of Nassau or Queens Counties of New York;
or (B) for reasons other than (i) for cause (as defined in the agreements), (ii)
voluntary resignation, except as a result of the actions specified under clause
(A) above or following a change of control, as defined in the agreements, (iii)
following the executive's attainment of mandatory retirement age for executive
officers (currently 70 years of age); (iv) death, (v) long term disability or
(vi) expiration of the term of the agreement, Mr. Keegan would be entitled to
severance benefits.
 
     The severance benefits to which Mr. Keegan would be entitled include (i)
continued life, medical and disability insurance benefits for the period from
termination of his employment through the remaining term of the agreement as if
he had continued in the employ of AFC or Astoria Federal through the end of the
term of the agreement (the "Unexpired Term"); (ii) a lump sum payment equal to
the present value of the salary, incentive compensation, pension, profit-sharing
and the GNYSB ESOP benefits he would have earned during the Unexpired Term
computed using a prescribed valuation method; (iii) accelerated vesting of all
outstanding options and restricted stock awards; (vi) at the election of AFC or
Astoria Federal, a cash settlement of all outstanding options and restricted
stock awards. In addition, if Mr. Keegan's employment terminates following a
change of control of AFC or Astoria Federal, his agreement with AFC provides
that for any taxable year in which Mr. Keegan would be liable for the payment of
excise taxes under Section 4999 of the Code with respect to any payment in the
nature of compensation paid by AFC or any of its affiliated companies, as a
result of such payments constituting an "excess parachute payments" under
Section 280G of the Code, or any successor thereto, then an amount will be paid
(the "Tax Payment") to him, or on his behalf, based upon a formula set forth in
the agreement, the effect of which would be to maintain the after-tax severance
benefit to which he would be entitled as described in the preceding paragraph
for the application of the excise tax specified in Section 4999 of the Code and
any federal, state and local income or other taxes to which he would be subject
as a result of the Tax Payment. Mr. Keegan's agreement with AFC provides that
any compensation or benefits provided to Mr. Keegan under the agreement with
Astoria Federal will be applied to offset the obligations under the agreement
with AFC.
 
     Change in Control Severance Agreements.  Under the terms of the Merger
Agreement, AFC will honor the change in control severance agreements dated
various dates between GNYSB and 73 individuals, in addition to those individuals
named above.
 
     Share Ownership.  As of April 30, 1997, directors and executive officers of
GNYSB and certain of their affiliates had a beneficial interest in 405,002
shares of GNYSB Common Stock (exclusive of shares which could be acquired upon
exercise of options) and 93,435 shares of GNYSB Series A Preferred Stock for
which they will receive the Merger Consideration.

     Stock Options.  GNYSB maintains the Long-Term Incentive Program, 1996
Equity Incentive Plan and 1996 Non-Employee Directors' Stock Option Plan
(collectively, the "GNYSB Option Plans"). At the Effective Time, each option to
purchase a share of GNYSB Common Stock that has been granted pursuant to the
GNYSB Option Plans and that is outstanding and unexercised at the Effective Time
(whether or not such option is otherwise vested or exercisable) (each, an
"Outstanding GNYSB Option") will be cancelled and will cease to be exercisable.
In consideration for such cancellation, AFC will, with respect to each
Outstanding GNYSB Option, pay to the holder thereof an amount equal to the
excess (if any) of (i) $19.00 over (ii) the price at which the holder may
acquire a share of GNYSB Common Stock upon exercise of such Outstanding GNYSB
Option multiplied by the number of shares of GNYSB Common Stock subject to such
option (the "Option Cashout Payment"). Any cash paid in connection with the
cancellation of GNYSB stock options issued pursuant to GNYSB Option Plans is
independent of the Merger Consideration paid pursuant to the procedures
discussed in "Merger Consideration and Election, Allocation and Proration
Procedures" herein and so is not considered for purposes of determining the
allocation and proration of the Merger Consideration among GNYSB shares.
 
     The following table sets forth, with respect to outstanding options held by
executive officers on April 30, 1997, the aggregate number of shares subject to
such options (whether or not exercisable), the number of shares with respect to
which such options are exercisable on September 30, 1997, the number of
additional shares with respect to which such options would become exercisable
because of a change in control, and based on figures provided by GNYSB, the
aggregate amount that would be required to be paid pursuant to the Merger
Agreement in consideration for the cancellation of such options.

- ---------------
 
* Based on calculations provided by GNYSB and $19.00 per share.
 
     In lieu of the payment indicated in the table above, Mr. Keegan and any two
other officers of the GNYSB to be designated by Mr. Keegan (currently expected
to be Messrs. Henchy and Harris) or any one or more of them may (and each of
Messrs. Keegan, Henchy and Harris have indicated that they currently expect to),
by written notice to AFC received not less than the day that is ten (10)
business days prior to the Effective Time, elect to convert all or any portion
of the Outstanding GNYSB Options held by them into options ("AFC Options") to
purchase shares of AFC Common Stock. Any such election will be irrevocable upon
receipt by AFC of the notice of election. As a result of such election, AFC will
issue to the electing individual AFC Options to purchase the number of shares of
AFC Common Stock (rounded down to the nearest whole share) equal to one-half the
number of shares of GNYSB Common Stock subject to the Outstanding GNYSB Options
being converted. The exercise price per share for each share of AFC Common Stock
subject to an AFC Option issued under an election will be equal to two times the
per share exercise price of the Outstanding GNYSB Option being converted into
such AFC Options, rounded up to the next whole cent. Each such AFC Option (i)
shall be fully vested and non-forfeitable, (ii) shall be exercisable at the same
time and for the same terms as the related Outstanding GNYSB Options, (iii)
shall not be subject to any condition, except as may be required under
applicable securities laws, including without limitation the continued
employment by AFC of the holder thereof, and (iv) shall be evidenced by an AFC
Option agreement. No cash payment will be made with respect to any portion of an
Outstanding GNYSB Option that
 
                                       67
<PAGE>   75
 
is converted into an AFC Option as aforesaid. Any holder of an Outstanding GNYSB
Option other than Mr. Keegan or the two individuals he designates may request a
conversion identical to that described above but AFC may, in its sole and
absolute discretion, determine whether to accept or deny such request.
 
     Each non-employee director of GNYSB is the beneficial owner of 8,000
outstanding GNYSB Options. The approximate economic benefit of the stock options
held by each of the non-employee directors of GNYSB is $34,000 (based on an
option to purchase 4,000 shares at an $11.50 exercise price and 4,000 shares at
an $17.875 exercise price).
 
     Any payment for GNYSB options, less any applicable withholding taxes, will
be made as soon as practicable following the Effective Time or the date on which
such holder delivers to AFC his or her written acceptance of an Option Cashout
Payment as full and complete consideration for the cancellation of each
Outstanding GNYSB Option held by him or her.
 
EFFECT ON GNYSB EMPLOYEE BENEFIT PLANS
 
     Each person who is employed by GNYSB immediately prior to the Effective
Time (a "GNYSB Employee") shall, at the Effective Time, become an employee (but
not an officer) of Astoria Federal. Beginning at the Effective Time, each GNYSB
Employee will serve Astoria Federal in the same capacity in which he or she
served GNYSB immediately prior to the Effective Time and upon the same terms and
conditions generally applicable to other employees of Astoria Federal with
comparable positions. If it is not practical to enroll GNYSB Employees as of the
Effective Time in a particular employee benefit plan or program maintained by
Astoria Federal for its employees (the "Astoria Federal Plans"), Astoria Federal
shall continue any comparable plan or program of GNYSB in effect immediately
prior to the Effective Time (the "GNYSB Plans") for a transition period. During
the transition period, GNYSB Employees shall continue to participate in GNYSB
Plans which are continued, and all other employees of Astoria Federal will
participate only in the Astoria Federal Plans and AFC plans, if any.
 
     Each of AFC and Astoria Federal will amend its respective employee benefit
plans and programs to recognize the service of each GNYSB Employee with GNYSB as
service with AFC and Astoria Federal for all purposes. Each of GNYSB's
tax-qualified plans will be amended, if necessary, to provide that all benefits
accrued by employees through the Effective Time will be fully vested without
regard to their length of service. Astoria Federal will amend its tax-qualified
defined benefit plan to recognize the service of each GNYSB Employee with GNYSB
as service with Astoria Federal for purposes of benefit accrual, with an offset
for vested benefits accrued under GNYSB's tax-qualified defined benefit plan.
GNYSB will take all necessary action to amend its tax-qualified defined benefit
plan, effective no later than the Effective Time, to cease all future benefit
accruals.
 
     If GNYSB Employees become eligible to participate in a medical, dental or
health plan of AFC or Astoria Federal, AFC will cause such plan to (A) waive any
preexisting condition limitations for conditions covered under the applicable
medical, health or dental plans of GNYSB and (B) honor any deductible and out of
pocket expenses incurred by the GNYSB Employees and their beneficiaries under
such plans during the portion of the calendar year prior to such participation.
If GNYSB Employees become eligible to participate in a life insurance plan
maintained by AFC or Astoria Federal, AFC will cause such plan to waive any
medical certification for the GNYSB Employees up to the amount of coverage the
GNYSB Employees had under the life insurance plan of GNYSB (but subject to any
limits on the maximum amount of coverage under the life insurance plan of AFC or
Astoria Federal). GNYSB will amend its SERP to provide that amounts includible
in the wages of a GNYSB Employee as a result of stock option exercises that
occur after the date of execution of the Merger Agreement and payments in
settlement of GNYSB obligations under any employment agreement or change of
control agreement will not be included as compensation for purposes of benefit
accrual under such plan. GNYSB will amend its SERP to cease all future benefit
accruals effective no later than the Effective Time, but such amendment will not
affect the calculation of any "make-up" payment provided for under any
employment agreement or change in control severance agreement.
 
     As long as the market price of GNYSB Common Stock exceeds approximately
$14.00, GNYSB expects that the GNYSB ESOP Trustee will convert the outstanding
shares of GNYSB Series A Preferred Stock into
 
                                       68
<PAGE>   76
 
GNYSB Common Stock prior to the consummation of the Merger. See "THE
MERGER -- Merger Consideration and Election, Allocation and Proration
Procedures -- GNYSB Series A Preferred Stock." Each such share of GNYSB Common
Stock will be converted into the Cash Consideration or the Stock Consideration
pursuant to election procedures to be established for participants in the GNYSB
ESOP. It is also anticipated that, in connection with the Merger, the GNYSB
ESOP's outstanding indebtedness will be repaid in full, any unallocated assets
remaining after such repayment will be allocated among participating employees
of GNYSB, the GNYSB ESOP will be terminated and the remaining assets, if any,
will be allocated to the accounts of participants.
 
OPERATIONS AFTER THE MERGER
 
     At the Effective Time, GNYSB will merge with and into Astoria Federal, with
Astoria Federal being the surviving entity. Under the terms of the Merger
Agreement, the charter and bylaws of Astoria Federal will be the charter and
bylaws of the surviving entity which will retain the name of Astoria Federal
Savings and Loan Association. Astoria Federal, as the resulting entity, will
operate under the policies, practices and procedures currently in place. All
assets and property (real, personal and mixed, tangible and intangible, choses
in actions, rights and credits) owned by GNYSB shall immediately become the
property of Astoria Federal. AFC and Astoria Federal do not currently anticipate
closing any of GNYSB's or Astoria Federal's branches following the Merger which
will result in a greater number of branches and the addition of a new market
area for AFC. Also, AFC will recognize some cost savings through consolidation
of back office functions. Also, see "-- Management of AFC after the Merger."
 
MANAGEMENT OF AFC AFTER THE MERGER
 
     The Merger Agreement provides that, at the Effective Time, the directors of
AFC and Astoria Federal, respectively, will be the directors of AFC and Astoria
Federal, respectively, immediately prior to the Effective Time of the Merger and
the directors of AFC and Astoria Federal will cause Mr. Gerard C. Keegan and one
other member of the GNYSB Board, selected by GNYSB and acceptable to AFC and who
was a member of the GNYSB Board on the date of the Merger Agreement, to be
elected and appointed to the boards of directors of AFC and Astoria Federal.
Except for the addition of Mr. Keegan, the executive officers of AFC and Astoria
Federal, respectively, will be the executive officers of AFC and Astoria
Federal, respectively, immediately prior to the Effective Time. At the Effective
Time, Mr. Keegan will become Vice Chairman and Chief Administrative Officer of
AFC and Astoria Federal. See "-- Interests of Certain Persons in the Merger."
 
INVOLVEMENT IN LEGAL PROCEEDINGS
 
     On April 3, 1997, a purported class action (the "Action") was commenced in
the Supreme Court of the State of New York (Kings County) entitled Leonard
Minzer and Harry Schipper v. Gerard C. Keegan, et al (Index No. 11546/1997)
against GNYSB and its directors and certain executive officers. The suit
alleges, among other things, that the directors and executive officers of GNYSB
have breached their fiduciary duties in entering into the Merger Agreement and
related arrangements. The complaint seeks, among other things, a preliminary and
permanent injunction against the Merger and the related transactions, an order
to the directors and executive officers of GNYSB to carry-out their fiduciary
duties and unspecified damages and costs. GNYSB believes that the allegations
made in the Action are without merit. On May 16, 1997, Mr. Keegan and GNYSB
filed a motion to dismiss the Action.

<PAGE>   77
 
                          CERTAIN RELATED TRANSACTIONS
 
STOCK OPTION AGREEMENT
 
     General.  As a condition to entering into the Merger Agreement, AFC
required that GNYSB enter into the Stock Option Agreement, which allows AFC to
purchase GNYSB Common Stock under certain circumstances. Pursuant to the Stock
Option Agreement, GNYSB granted to AFC the Option to purchase 2,721,536 shares
of GNYSB Common Stock (representing approximately 19.9% of the issued and
outstanding shares of the GNYSB Common Stock on March 29, 1997) (subject to
adjustment such that in no event may AFC acquire shares of GNYSB Common Stock
representing more than 19.9% of the issued and outstanding shares of such stock)
at an exercise price of $17.875 per share (subject to adjustment). The Option
may only be exercised upon the occurrence of certain "Purchase Events" which are
described herein (none of which has occurred to the best of AFC's or GNYSB's
knowledge as of the date of this Joint Proxy Statement-Prospectus).
 
     Effect of Stock Option Agreement.  The Stock Option Agreement is intended
to increase the likelihood that the Merger will be consummated in accordance
with the terms of the Merger Agreement. Consequently, certain aspects of the
Stock Option Agreement may have the effect of discouraging persons who might now
or prior to the consummation of the Merger be interested in acquiring all of or
a significant interest in GNYSB from considering or proposing such an
acquisition, even if such persons were prepared to pay a higher price per share
for the GNYSB Common Stock than the value per share contemplated by the Merger
Agreement. The acquisition of GNYSB, a significant portion of its consolidated
assets or an interest in GNYSB, or an agreement to do so, could cause the Option
to become exercisable. The existence of such Option could significantly increase
the cost to a potential acquiror of acquiring GNYSB compared to its cost had the
Stock Option Agreement not been executed. Such increased costs might discourage
a potential acquiror from considering or proposing an acquisition or might
result in a potential acquiror proposing to pay a lower per share price to
acquire GNYSB than it might otherwise have proposed to pay. The management of
GNYSB believes that the exercise of the Option is likely to prohibit any
acquiror of GNYSB from accounting for any acquisition of GNYSB using the pooling
of interests accounting method for a period of two years. This could discourage
or preclude an acquisition by other banking organizations.
 
     Terms of Stock Option Agreement.  The following is a brief summary of
certain provisions of the Stock Option Agreement, which is attached hereto as
Appendix B. The following summary is qualified in its entirety by reference to
the Stock Option Agreement.
 
     If AFC is not in material breach of the Stock Option Agreement or the
Merger Agreement and if no injunction or other court order against delivery of
the shares covered by the related Option is in effect, AFC may exercise the
Option, in whole or in part, at any time and from time to time upon the
occurrence of the following (each a "Purchase Event"):
 
          (i) Without AFC's prior written consent, GNYSB taking certain actions
     (each an "Acquisition Transaction") including authorizing, recommending or
     proposing, or entering into an agreement with any third party to effect (A)
     a merger, consolidation or similar transaction involving GNYSB or any of
     its significant subsidiaries, (B) the sale, lease, exchange or other
     disposition of 25% or more of the consolidated assets or deposits of GNYSB
     or (C) the issuance, sale or other disposition of 25% or more of the voting
     power of GNYSB; or
 
          (ii) Any third party acquiring or having the right to acquire 20% or
     more of the voting power of GNYSB;
 
provided, that the Option will terminate upon the earliest to occur of certain
events, including:
 
          (i) the Effective Time;
 
          (ii) termination of the Merger Agreement in accordance with the terms
     thereof prior to the occurrence of a Purchase Event or a Preliminary
     Purchase Event other than a termination thereof by AFC under certain
     circumstances (a "Default Termination");
 
                                       70
<PAGE>   78
 
          (iii) 15 months after a Default Termination; or
 
          (iv) 15 months after termination of the Merger Agreement (other than a
     Default Termination) following the occurrence of a Purchase Event or a
     Preliminary Purchase Event.
 
     The term "Preliminary Purchase Event" means any of the following events:
 
          (i) Commencement by any third party of a tender offer or exchange
     offer to purchase 20% or more of the voting power of GNYSB (such an offer
     being referred to herein as a "Tender Offer" or an "Exchange Offer,"
     respectively); or
 
          (ii) Failure of the stockholders of GNYSB to approve the Merger
     Agreement or failure of GNYSB to have held such meeting or the GNYSB Board
     shall have withdrawn or modified in a manner adverse to AFC the
     recommendation of the GNYSB Board with respect to the Merger Agreement, in
     each case after public announcement that a third party (A) proposes to
     engage in an Acquisition Transaction, (B) commences a Tender Offer or (C)
     files an application under certain federal statutes relating to the
     regulation of banks and other financial institutions or their holding
     companies to engage in an Acquisition Transaction; or
 
          (iii) Any third party proposal to GNYSB or its stockholders publicly,
     or in any writing that becomes publicly disclosed, to engage in an
     Acquisition Transaction; or
 
          (iv) After a proposal is made by a third party to GNYSB or its
     stockholders to engage in an Acquisition Transaction, or such third party
     states its intention to GNYSB to make such a proposal if the Merger
     Agreement terminates, GNYSB breaches any representation, warranty, covenant
     or agreement in the Merger Agreement and such breach would entitle AFC to
     terminate the Merger Agreement.
 
     In the event that GNYSB shall enter into an agreement (i) to consolidate
with or merge into any person, other than AFC or one of its subsidiaries, and
GNYSB shall not be the continuing or surviving corporation of such consolidation
or merger, (ii) to permit any person, other than AFC or one of its subsidiaries,
to merge into GNYSB and GNYSB shall be the continuing or surviving corporation,
but, in connection with such merger, the then outstanding shares of GNYSB Common
Stock shall be changed into or exchanged for stock or other securities of GNYSB
or any other person or cash or any other property, or the outstanding shares of
GNYSB Common Stock immediately prior to such merger shall after such merger
represent less than 50% of the outstanding shares and share equivalents of the
merged company, or (iii) to sell or otherwise transfer all or substantially all
of its assets or deposits to any person, other than AFC or one of its
subsidiaries, then, and in each such case, the agreement governing such
transaction shall make proper provisions so that the Option shall, upon the
consummation of any such transaction and upon the terms and conditions set forth
in the Stock Option Agreement, be converted into, or exchanged for, an option
(the "Substitute Option"), at the election of AFC, of either (A) the Acquiring
Corporation (as defined in the Stock Option Agreement), (B) any person that
controls the Acquiring Corporation or (C) in the case of a merger described in
clause (ii), GNYSB (such person being referred to as "Substitute Option GNYSB").
 
     Both the Merger Agreement and the Stock Option Agreement contain provisions
that limit the aggregate realizable profit to AFC from the Option and the
Termination Fee to $10 million.
 
AMENDMENT TO GNYSB RIGHTS AGREEMENT
 
     On June 14, 1990, GNYSB adopted the GNYSB Rights Agreement pursuant to
which GNYSB's stockholders of record as of June 25, 1990 each received a
dividend of one GNYSB Right for each outstanding share of GNYSB Common Stock to
holders. In connection with the execution of the Merger Agreement, GNYSB amended
the GNYSB Rights Agreement to clarify that for purposes of determining whether
AFC (as well as its affiliates and associates) is an Acquiring Person, as
defined in the GNYSB Rights Agreement, AFC shall not be deemed to be a
Beneficial Owner, as defined in the GNYSB Rights Agreement, or to beneficially
own any securities as a result of GNYSB's obligation to merge under the Merger
Agreement. See "COMPARISON OF CERTAIN RIGHTS OF STOCKHOLDERS -- Rights
Plans -- GNYSB."
 
                                       71
<PAGE>   79
 
RESALES OF AFC COMMON STOCK
 
     The shares of AFC Common Stock issued pursuant to the Merger Agreement will
be freely transferable under the Securities Act except for shares issued to any
stockholder who may be deemed to be an "affiliate" of GNYSB for purposes of Rule
145 under the Securities Act as of the date of the GNYSB Meeting. Affiliates may
not sell their shares of AFC Common Stock acquired in connection with the Merger
except pursuant to an effective registration statement under the Securities Act
covering such shares or in compliance with Rule 145 under the Securities Act or
another applicable exemption from the registration requirements of the
Securities Act. Persons who may be deemed to be affiliates of GNYSB generally
include individuals or entities that control, are controlled by or are under
common control with GNYSB and may include certain officers and directors of
GNYSB as well as principal stockholders of GNYSB.
 
     GNYSB agreed in the Merger Agreement to cause each affiliate of GNYSB to
enter into an agreement with AFC providing that such persons will not sell,
transfer or otherwise dispose of shares of GNYSB Common Stock owned by such
person or AFC Common Stock to be received by such person in the Merger except in
compliance with the applicable provisions of the Securities Act and the rules
and regulations thereunder. GNYSB has delivered these agreements to AFC.
 
                             CERTIFICATE AMENDMENT
 
     In connection with the Merger, the AFC Board has approved the Certificate
Amendment to change the par value of AFC's authorized preferred stock from $0.01
to $1.00 per share. Approval of the Certificate Amendment requires the
affirmative vote of the holders of at least a majority of the issued and
outstanding shares of AFC Common Stock. The purpose of the increase in par value
to $1.00 per share is to have available AFC Preferred Stock that has the same
par value as the GNYSB Series B Preferred Stock so that the par value of the AFC
Series B Preferred Stock is the same as the GNYSB Series B Preferred Stock. The
Certificate Amendment provides that at such time as the AFC Series B Preferred
Stock is no longer outstanding, the par value of AFC Preferred Stock
automatically, without any further action by AFC's stockholders, will be reduced
back to $0.01 per share.
 
     The text of the Certificate Amendment is as follows:
 
     Section Fourth A.1. of the Certificate of Incorporation of Astoria
Financial Corporation is hereby restated in its entirety as follows:
 
          1. Five million (5,000,000) shares of Preferred Stock, par value one
     dollar ($1.00) per share (the "Preferred Stock"); provided, however, that
     at such time as the Astoria Financial Corporation 12% Noncumulative
     Perpetual Preferred Stock, Series B, issued pursuant to the terms of the
     Agreement and Plan of Merger, dated as of March 29, 1997, by and among
     Astoria Financial Corporation, Astoria Federal Savings and Loan Association
     and The Greater New York Savings Bank, is no longer outstanding, then
     Section Fourth A.1. of the Certificate of Incorporation shall
     automatically, and without any further action of the stockholders of
     Astoria Financial Corporation, be restated in its entirety as follows:
 
             1. Five million (5,000,000) shares of Preferred Stock, par value
        one cent ($0.01) per share (the "Preferred Stock"); and
 
     The Certificate Amendment will become effective only upon consummation of
the Merger. Regardless of whether the Merger Agreement is approved by
stockholders of GNYSB or the issuance of the Merger Shares is approved by
stockholders of AFC, failure of AFC's stockholders to approve the Certificate
Amendment will prevent consummation of the Merger unless such condition is
waived by GNYSB.
 
     THE AFC BOARD HAS UNANIMOUSLY DETERMINED THAT THE MERGER IS IN THE BEST
INTERESTS OF ITS STOCKHOLDERS AND, ACCORDINGLY, HAS UNANIMOUSLY APPROVED THE
TRANSACTIONS REQUIRED FOR THE CONSUMMATION OF THE MERGER AND UNANIMOUSLY
RECOMMENDS A VOTE FOR APPROVAL OF THE CERTIFICATE AMENDMENT BY AFC'S
STOCKHOLDERS.

(1) State Street Bank and Trust Company ("State Street") is the trustee of the
    Astoria Federal Employee Stock Ownership Plan (the "Astoria Federal ESOP"),
    which is administered by the Astoria Federal ESOP Committee consisting of
    four (4) officers of Astoria Federal, one of whom is an executive officer of
    Astoria Federal. As of December 31, 1996, State Street held 2,612,324 shares
    of AFC Common Stock for the benefit of the participants of the Astoria
    Federal ESOP. Under the terms of the Astoria Federal ESOP, the Trustee votes
    the shares held by the Astoria Federal ESOP Trust based upon directions
    received from the participants as "named fiduciaries" in the Astoria Federal
    ESOP. As of December 31, 1996, approximately 653,212 shares were allocated
    to participants. For voting purposes, each participant as a "named
    fiduciary" will be eligible to direct the Trustee how to vote at the AFC
    Meeting as to the number of shares of AFC Common Stock which have been
    allocated to his or her account under the Astoria Federal ESOP. The
    remaining unallocated shares and any allocated shares with respect to which
    no voting instructions have been received will be voted by the Trustee at
    the AFC Meeting in the same manner and proportion as the allocated shares
    with respect to which voting instructions have been received, so long as
    such vote is in accordance with the provisions of ERISA. Due to the
    requirements of ERISA, the trustee is deemed to have shared voting power as
    to all shares held in the Astoria Federal ESOP Trust. According to a filing
    on Schedule 13G under the Exchange Act dated February 10, 1997, State Street
    also holds 104,100 shares as trustee of various collective investment funds
    for employee benefit plans of other companies and other index accounts, as
    to which State Street has sole voting and dispositive power.
(2) According to a filing on Schedule 13G, dated February 14, 1997, under the
    Exchange Act Edward C. Johnson 3d and Abigail P. Johnson own 12.0 % and 24.5
    %, respectively, of the outstanding voting common stock of FMR Corp. Mr.
    Johnson is Chairman of FMR Corp. Ms. Johnson is a director of FMR Corp.
    Members of Mr. Johnson's family and trusts beneficially own approximately
    49% of the voting power of FMR Corp. These family members may be deemed to
    form a controlling group with respect to FMR Corp. Fidelity Management &
    Research Company ("FMRC"), a wholly owned subsidiary of FMR Corp. and an
    investment advisor registered under Section 203 of the Investment Advisors
    Act of 1940, is the beneficial owner of 816,000 shares of AFC Common Stock
    as a result of acting as investment advisor to various investment companies
    registered under Section 8 of the Investment Company Act of 1940. Fidelity
    Management Trust Company, a wholly owned subsidiary of FMR Corp., is the
    beneficial owner of 714,170 shares of AFC Common Stock. Edward C. Johnson 3d
    and FMR Corp., through its control of Fidelity Management Trust Company,
    each claim sole dispositive power over 714,170 shares of AFC Common Stock
    and sole power to direct the voting of 582,570 shares, and no power to vote
    or to direct the voting of 131,600 shares of AFC Common Stock owned by
    institutional account(s).

     The FDIC Rules and Regulations require the GNYSB's directors, executive
officers and holders of more than 10% of the GNYSB Common Stock to file with the
FDIC initial reports of ownership and reports of changes in ownership of common
stock and other equity securities of GNYSB. GNYSB believes that during the
fiscal year ended December 31, 1996, its directors, executive officers and
holders of more than 10% of the GNYSB Common Stock complied with all filing
requirements.
 
                       CERTAIN REGULATORY CONSIDERATIONS
 
GENERAL
 
     Astoria Federal, as a federal savings and loan association, is subject to
extensive regulation, examination and supervision by the OTS, as its chartering
agency, and by the FDIC, as the insurer of its deposits. Astoria Federal is a
member of the Federal Home Loan Bank ("FHLB") System, and its deposit accounts
are insured up to applicable limits by the FDIC under the SAIF. AFC, as a
savings and loan holding company, is registered with the OTS and is subject to
OTS regulations, examination, supervision and reporting requirements. GNYSB is
subject to extensive regulation, examination and supervision by the Banking
Department, as its chartering agency, and by the FDIC, as the insurer of its
deposits.
 
     The earnings of AFC and Astoria Federal and the earnings of GNYSB are
affected by general economic conditions, management policies and the legislative
and governmental actions of various federal and state regulatory authorities,
including the Board of Governors of the Federal Reserve System (the "Federal
Reserve Board"), the OTS, the FDIC and the Banking Department. Additionally,
there are numerous governmental requirements and regulations that affect the
activities of AFC, GNYSB and their respective subsidiaries. Any change in
applicable law or regulation might have a material effect on the business and
prospects of AFC and GNYSB.
 
     The description of statutory provisions and regulations applicable to
federally chartered savings associations and to savings and loan holding
companies set forth in this document do not purport to be complete descriptions
of such statutes and regulations and their effects on AFC or Astoria Federal.

<PAGE>   87
 
BUSINESS ACTIVITIES OF FEDERAL SAVINGS ASSOCIATIONS
 
     The activities of federally chartered savings associations are governed by
the Home Owner's Loan Act, as amended ("HOLA") and, in certain respects, by the
Federal Deposit Insurance Act ("FDI Act"). The federal banking statutes, among
other things, (i) restrict the use of brokered deposits by federally chartered
savings associations that are not well-capitalized, (ii) prohibit the
acquisition of any corporate debt security that is not rated in one of the four
highest rating categories, (iii) restrict the aggregate amount of loans secured
by non-residential real estate property, (iv) permit savings and loan holding
companies to acquire up to 5% of the voting shares of non-subsidiary savings
associations or savings and loan holding companies without prior approval of the
OTS, (v) permit bank holding companies to acquire savings associations and (vi)
require the federal banking agencies to establish by regulation uniform
standards for real estate lending. Under HOLA, Astoria Federal has the authority
to make certain loans or investments not exceeding 5.0% of its total assets on
each of (a) non-conforming loans (loans in excess of the specific limitations of
the HOLA) and (b) construction loans without security for the purpose of
financing what is or is expected to be residential property. To assure repayment
of such loans, an association would rely substantially on the borrower's general
credit standing, personal guarantees and projected future income on the
properties.
 
RESTRICTIONS ON PAYMENT OF DIVIDENDS
 
     AFC is a separate legal entity from Astoria Federal and its subsidiaries. A
substantial portion of the revenues of AFC (on an unconsolidated basis)
available for payment of dividends to its stockholders will result from the
amounts paid to it, directly or indirectly, in the form of dividends from
Astoria Federal. OTS regulations impose limitations upon all capital
distributions by savings associations, such as cash dividends, payments to
repurchase or otherwise acquire its shares, payments to stockholders of another
institution in a cash-out merger and other distributions charged against
capital. The regulations establish three tiers of institutions, which are based
primarily on an institution's capital level. An institution that exceeds all
fully phased-in capital requirements before and after a proposed capital
distribution ("Tier I Association") and has not been advised by the OTS that it
is in need of more than normal supervision, could, after prior notice but
without the approval of the OTS, make capital distributions during a calendar
year equal to the greater of: (i) 100% of its net income to date during the
calendar year plus the amount that would reduce by one-half its "surplus capital
ratio" (the excess capital over its fully phased-in capital requirements) at the
beginning of the calendar year or (ii) 75% of its net income for the previous
four quarters. Any additional capital distributions would require prior
regulatory approval. As of March 31, 1997, Astoria Federal was a Tier I
Association. In the event Astoria Federal's capital fell below its fully-phased
in requirement or the OTS notified Astoria Federal that it was in need of more
than normal supervision, Astoria Federal's ability to make capital distributions
could be restricted. In addition, the OTS could prohibit a proposed capital
distribution by any institution, which would otherwise be permitted by the
regulation, if the OTS determines that such distribution would constitute an
unsafe or unsound practice. Furthermore, under the OTS' prompt corrective action
regulations, Astoria Federal would be prohibited from making any capital
distributions if, after the distribution, Astoria Federal would not comply with
applicable minimum capital requirements. See "-- Capital Requirements." At the
time of the conversion to stock form, Astoria Federal was required to establish
a liquidation account in an amount equal to its capital as of June 30, 1993. As
part of the acquisition of Fidelity New York, F.S.B. ("Fidelity"), Astoria
Federal established a similar liquidation account equal to the remaining
liquidation account balance previously maintained by Fidelity as a result of its
conversion from mutual to stock form of ownership. The liquidation account is
reduced to the extent that eligible account holders reduce their qualifying
deposits. In the unlikely event of a complete liquidation of Astoria Federal,
each eligible account holder will be entitled to receive a distribution from the
liquidation account. Astoria Federal may not declare or pay cash dividends on or
repurchase any of its shares of common stock if the effect thereof would cause
stockholders' equity to be reduced below the amount required for the liquidation
account.
 
CAPITAL REQUIREMENTS
 
     There is no capital requirement applicable to AFC as a savings and loan
holding company, other than those applicable to Astoria Federal. With respect to
Astoria Federal, the OTS capital regulations require
 
                                       80
<PAGE>   88
 
savings associations to meet three capital ratios: a 1.5% tangible capital
ratio, a 3% leverage (core capital) ratio and an 8% risk-based capital ratio.
Core capital is defined as common stockholders' equity (including retained
earnings but excluding net unrealized gains and losses from available-for-sale
debt securities), certain noncumulative perpetual preferred stock and related
surplus, minority interests in equity accounts of consolidated subsidiaries,
less intangibles other than certain qualifying supervisory intangible assets,
certain mortgage servicing rights and certain other assets as defined by OTS
capital regulations. The OTS regulations also require that, in meeting the
tangible, leverage, and risk-based capital ratios, institutions must deduct
investments in and loans to subsidiaries engaged in activities not permissible
for a national bank.
 
     The risk-based capital standard for savings associations requires the
maintenance of total risk-based capital (which is defined as core capital plus
supplementary capital less certain adjustments) to risk weighted assets of 8%.
In determining the amount of risk-weighted assets, all assets, including certain
off balance sheet assets, are multiplied by a risk-weight of 0% to 100%, as
assigned by the OTS capital regulation based on the risks the OTS believes are
inherent in the type of asset. The components of core capital are equivalent to
those discussed earlier under the 3% leverage ratio. The components of
supplementary capital currently include cumulative preferred stock, long-term
perpetual preferred stock, mandatory convertible securities, subordinated debt
and intermediate preferred stock and allowance for loan and lease losses.
Allowance for loan and lease losses includible in supplementary capital is
limited to a maximum of 1.25% of risk-weighted assets. Overall, the amount of
supplementary capital counted toward total capital cannot exceed 100% of core
capital. In addition, certain assets are required to be deducted from risk-based
capital, such as certain equity investments and construction loans with
loan-to-value ratios exceeding 80%.
 
     Financial Institutions Reform, Recovery and Enforcement Act of 1989
requires that the OTS and other federal banking agencies revise the risk-based
capital standards, with appropriate transition rules, to ensure that they take
into account interest rate risk ("IRR"), concentration of risk and the risks of
non-traditional activities. The OTS adopted regulations, effective January 1,
1994, that set forth the methodology for calculating an interest rate risk
component to be incorporated into the OTS risk-based capital regulations. The
OTS has indefinitely deferred its requirement of the interest rate risk
component in the calculation of an institution's risk-based capital
requirements. The OTS continues to monitor the IRR of individual institutions
and retains the right to impose minimum capital requirements on individual
institutions. Based on Astoria Federal's IRR profile and the level of interest
rates at December 31, 1996, as well as Astoria Federal's level of risk-based
capital at December 31, 1996, management believes that Astoria Federal does not
have a greater than normal level of IRR as measured under the OTS rule and would
not be required to hold additional capital against its IRR as a result of the
rule.
 
     At March 31, 1997, Astoria Federal met each of its capital requirements.
The following table sets forth the regulatory capital calculations of Astoria
Federal at March 31, 1997, calculated in accordance with applicable requirements
of the OTS. At March 31, 1997, Astoria Federal is a "well capitalized"
institution.

     On a pro forma basis after giving effect to the Merger, Astoria Federal
would remain a "well capitalized" institution with pro forma tangible, leverage

31, 1997.
 
PROMPT CORRECTIVE REGULATORY ACTION
 
     FDICIA establishes a system of prompt corrective action to resolve the
problems of undercapitalized institutions. Under this system, the banking
regulators are required to take certain supervisory actions against
undercapitalized institutions, the severity of which depends upon the
institution's degree of capitalization.
 
                                       81
<PAGE>   89
 
Generally, subject to a narrow exception, FDICIA requires the applicable banking
regulator to appoint a receiver or conservator for an institution that is 
critically undercapitalized.
 
     Under the OTS regulations, generally, a federally chartered savings
association is treated as "well capitalized" if its total risk-based capital
ratio is 10% or greater, its Tier 1 risk-based capital ratio is 6% or greater,
and its leverage ratio is 5% or greater, and it is not subject to any order or
directive by the OTS to meet a specific capital level. A federally chartered
savings association is treated as adequately capitalized if its ratio of total
capital to risk-weighted assets is at least 8%, its Tier 1 risk-based capital
ratio is at least 4%, and its leverage ratio is at least 4% (3% if the
institution receives the highest rating on the regulatory rating system). A
federally chartered savings association that has a total risk-based capital
ratio of less than 8% or a leverage ratio or a Tier 1 risk-based capital ratio
of less than 4% is considered to be "undercapitalized." A federally chartered
savings association that has a total risk-based capital ratio of less than 6%, a
Tier 1 risk-based capital ratio of less than 3% or a leverage ratio of less than
3% is considered to be "significantly undercapitalized," and a federally
chartered savings association that has a tangible-capital to assets ratio equal
to or less than 2% is deemed to be "critically undercapitalized." Generally, a
capital restoration plan must be filed with the OTS within 45 days of the date
an association receives notice that it is "undercapitalized," "significantly
undercapitalized" or "critically undercapitalized." In addition, various
mandatory supervisory actions become immediately applicable to the institution,
including restrictions on growth of assets and other forms of expansion. The OTS
could also take any one of a number of discretionary supervisory actions,
including the issuance of a capital directive and the replacement of senior
executive officers and directors. As of March 31, 1997, Astoria Federal was
considered "well capitalized" by the OTS.
 
     "Undercapitalized" depository institutions are subject to growth
limitations and are required to submit a capital restoration plan.
"Significantly undercapitalized" institutions are subject to more severe
restrictions. The OTS may not accept a capital restoration plan without
determining, among other things, that the plan is based on realistic assumptions
and is likely to succeed in restoring the depository institution's capital. In
addition, for a capital restoration plan to be acceptable, the depository
institution's parent holding company must guarantee that the institution will
comply with such capital restoration plan. The aggregate liability of the parent
holding company is limited to the lesser of (i) an amount equal to the five
percent of the depository institution's total assets at the time it became
"undercapitalized," and (ii) the amount which is necessary (or would have been
necessary) to bring the institution into compliance with all capital standards
applicable with respect to such institution as of the time it fails to comply
with the plan. If a depository institution fails to submit an acceptable plan,
it is treated as if it is "significantly undercapitalized." In the event of a
savings and loan holding company's bankruptcy, any commitment by the savings and
loan company to a federal bank regulatory agency to maintain the capital of a
subsidiary depository institution will be assumed by the bankruptcy trustee and
entitled to a priority of payment.
 
IMPACT OF RECENT LEGISLATION
 
     Deposit Insurance -- SAIF Recapitalization.  For the first three quarters
of 1996, SAIF-insured institutions paid deposit insurance assessment rates on an
annual basis of $0.23 to $0.31 per $100 of deposits. As a well capitalized
institution, Astoria Federal paid deposit insurance assessment rates on an
annual basis of $0.23 per $100 of deposits or $7.4 million for the first three
quarters of 1996. In contrast, BIF-insured institutions that were well
capitalized and without any significant supervisory concerns paid the minimum
annual assessment of $2,000, and all other BIF-insured institutions paid deposit
insurance assessments at annual rates of $0.03 to $0.27 per $100 of deposits.
 
     In response to the SAIF/BIF assessment disparity, the Deposit Insurance
Funds Act of 1996 (the "Funds Act") was enacted into law on September 30, 1996.
The Funds Act amended the FDI Act in several ways to recapitalize the SAIF and
reduce the disparity in the assessment rates for the BIF and the SAIF. The Funds
Act authorized the FDIC to impose a special one-time assessment on all
institutions with SAIF-assessable deposits in the amount necessary to
recapitalize the SAIF. As implemented by the FDIC, institutions with
SAIF-assessable deposits paid a special assessment, subject to adjustment, of
65.7 basis points per $100 of the institution's SAIF-assessable deposits. The
special assessment was based on the amount of SAIF-assessable deposits held on
March 31, 1995. The Funds Act provides that the amount of the special
 
                                       82
<PAGE>   90
 
assessment is deductible for federal income tax purposes for the taxable year in
which the special assessment is paid. Based on the foregoing, the special
assessment for Astoria Federal of $28.5 million (before taxes) was charged
against income during the quarter ended September 30, 1996 and paid in November
1996.
 
     In view of the recapitalization of the SAIF, the FDIC reduced the
assessment rates for SAIF-assessable deposits. For periods beginning on October
1, 1996 the annual rates were reduced to a range of 18 to 27 basis points, and
beginning on January 1, 1997, the effective annual rates were reduced to a range
of 0 to 27 basis points. The Funds Act also provides that the FDIC cannot assess
regular insurance assessments for an insurance fund unless required to maintain
or to achieve the designated reserve ratio of 1.25% of insured deposits, except
on those of its member institutions that are not classified as "well
capitalized" or that have been found to have "moderately severe" or
"unsatisfactory" financial, operational or compliance weaknesses. Astoria
Federal has not been so classified by the FDIC or the OTS.
 
     In addition, the Funds Act expanded the assessment base to provide funds
for the payment of interest on the bonds issued in the late 1980s by the
Financing Corporation (the "FICO bonds") to recapitalize the now defunct Federal
Savings and Loan Insurance Corporation to include the deposits of both BIF- and
SAIF-insured institutions beginning January 1, 1997. Until December 31, 1999, or
such earlier date on which the last savings association ceases to exist
(relative to charter form), the rate of assessment for BIF-assessable deposits
will be one-fifth of the rate imposed on SAIF-assessable deposits. The annual
rate of assessment for the payments on the FICO bonds for the semiannual period
beginning on January 1, 1997 was 0.013% for BIF-assessable deposits and 0.0648%
for SAIF-assessable deposits, and for the semiannual period beginning on July 1,
1997 will be 0.0126% and 0.0630%, respectively. Assuming that the designated
reserve ratio is maintained by the SAIF, Astoria Federal, as long as it
maintains its regulatory status, will pay substantially lower regular
assessments compared to those paid by Astoria Federal in recent years. Based on
the foregoing, Astoria Federal's SAIF assessment rate was 4.5 basis points for
the last quarter of 1996, and Astoria Federal's annual SAIF assessment rate for
1997 is zero basis points. As a result, AFC expects a reduction in its total
1997 expense for the assessment for deposit insurance and FICO obligations of
$6.7 million from the 1996 expense incurred.
 
     The Funds Act also provides for the merger of the BIF and SAIF on January
1, 1999, with such merger being conditioned upon the prior elimination of the
thrift charter and the development of a new common charter. The Funds Act
directs the Secretary of the Treasury to conduct a study of relevant factors
with respect to the development of a common charter for all insured depository
institutions and to report the Secretary's conclusions and findings to the
Congress. The Secretary of the Treasury has recommended that the separate
charter for thrifts be eliminated only if other legislation is adopted that
permits bank holding companies to engage in certain non-financial activities.
Absent legislation permitting such non-financial activity, the Secretary of the
Treasury recommended retention of the thrift charter. The Secretary of the
Treasury also recommended the merger of the BIF and the SAIF irrespective of
whether the thrift charter is eliminated. Other proposed legislation has been
introduced in Congress that would require thrift institutions to convert to bank
charters. These bills include provisions that would (i) apply the restrictions
on activities applicable to multiple savings and loan holding companies and bank
holding companies to unitary savings and loan building companies and (ii)
eliminate the savings association charter and require savings associations to
become banks and simultaneously abolish the OTS and its supervisory role over
savings and loan holding companies. Although no assurances can be given as to
whether legislation will be enacted to eliminate the thrift charter or if
enacted, what powers would be available to Astoria Federal under any new or
revised depository institution charter, management of AFC and Astoria Federal
believes that such legislation will not significantly impact the core business
activities of Astoria Federal. Management intends to continue to closely monitor
such developments.
 
     Recapture of Bad Debt Reserves.  Prior to the enactment of the Small
Business Job Protection Act of 1996 (the "1996 Act"), on August 20, 1996, thrift
institutions such as Astoria Federal, which met certain definitional tests
primarily relating to their assets and the nature of their business, for federal
income tax purposes, were permitted to establish tax reserves for bad debts and
to make annual additions thereto, which additions could be deducted, within
specified limitations, in arriving at their taxable income. Astoria Federal's
deduction with respect to "qualifying loans," which are generally loans secured
by certain interest in real
 
                                       83
<PAGE>   91
 
property, could be computed using an amount based on Astoria Federal's actual
loss experience (the "Experience Method"), or a percentage equal to 8.0% of
Astoria Federal's taxable income (the "PTI Method"), computed without regard to
this deduction and with additional modifications and reduced by the amount of
any permitted addition to the non-qualifying reserve. Similar deductions for
additions to Astoria Federal's bad debt reserve were permitted under the New
York State Franchise Tax and the New York City Financial Corporation Tax;
however, for purposes of these taxes, the effective allowable percentage under
the PTI method was 32% rather than 8%.
 
     Under the 1996 Act, the PTI Method was repealed and Astoria Federal, as a
"large bank" (one with assets having an adjusted basis of more than $500
million), will be unable to make additions to its tax bad debt reserve, will be
permitted to deduct bad debts only as they occur and will be required to
recapture (that is, take into taxable income) over a six-year period, beginning
with Astoria Federal's taxable year beginning January 1, 1996, the excess of the
balance of such reserves (other than the supplemental reserve) as of December
31, 1995 over the balance of such reserves as of December 31, 1987. However,
under the 1996 Act, such recapture requirements will be suspended for each of
the two successive taxable years beginning January 1, 1996 in which Astoria
Federal originates a minimum amount of certain residential loans during such
years that is not less than the average of the principal amounts of such loans
made by Astoria Federal during its six taxable years preceding January 1, 1996.
Since Astoria Federal has already provided a deferred income tax liability for
financial reporting purposes, there will be no adverse impact to Astoria
Federal's financial condition or results of operations from the enactment of
this legislation.
 
     The New York State and New York City tax laws have been amended to prevent
a similar recapture of Astoria Federal's bad debt reserve, and to permit
continued future use of the bad debt reserve method for purposes of determining
the Astoria Federal's New York State and New York City tax liabilities, in
either case so long as the Astoria Federal continues to satisfy the New York
State and New York City definitional tests related to its assets and the nature
of its business, which are similar to the former federal income tax tests,
discussed above.
 
TRANSACTIONS WITH RELATED PARTIES
 
     In addition to Sections 23A and 23B of the Federal Reserve Act ("FRA"),
which limit Astoria Federal's authority to engage in transactions with
"affiliates" (i.e., any company that controls or is under common control with an
institution, which for Astoria Federal would be AFC), OTS regulations prohibit
savings associations from lending to any affiliate that is engaged in activities
that are not permissible for bank holding companies under Section 4(c) of the
Bank Holding Company Act ("BHC Act"). Further, no savings association may
purchase the securities of any affiliate other than a subsidiary.
 
FEDERAL HOME LOAN BANK SYSTEM
 
     Astoria Federal is a member of the FHLB System, which consists of 12
regional FHLBs. The FHLB provides a central credit facility primarily for 
member institutions. Astoria Federal, as a member of the FHLB-NY, is required
to acquire and hold shares of capital stock in FHLB-NY in an amount at least
equal to 1% of the aggregate principal amount of its unpaid residential
mortgage loans and similar obligations at the beginning of each year, 0.3% of
total assets, or 1/20% of its advances from the FHLB-NY, whichever is greater.
Astoria Federal was in compliance with this requirement with an investment in
FHLB-NY stock at December 31, 1996, of $32.4 million.
 
     For each of the years ended December 31, 1996 and 1995, dividends from the
FHLB-NY to Astoria Federal amounted to $2.0 million, and for the year ended
December 31, 1994, dividends amounted to $1.5 million.
 
OTHER REGULATIONS APPLICABLE TO FEDERAL SAVINGS ASSOCIATIONS
 
     Qualified Thrift Lender ("QTL") Test.  The HOLA requires savings
associations to meet a QTL test. Under the QTL test, a savings association is
required to maintain at least 65% of its "portfolio assets" (total assets less
(i) specified liquid assets up to 20% of total assets, (ii) intangibles,
including goodwill, and (iii) the
 
                                       84
<PAGE>   92
 
value of property used to conduct business) in certain "qualified thrift
investments" (primarily residential mortgages and related investments, including
certain mortgage-backed and mortgage-related securities) on a monthly basis in 9
out of every 12 months.
 
     A savings association that fails the QTL test and does not convert to a
bank charter generally will be prohibited from: (i) engaging in any new activity
not permissible for a national bank, (ii) paying dividends not permissible under
national bank regulations, (iii) obtaining advances from any FHLB, and (iv)
establishing any new branch office in a location not permissible for a national
bank in the association's home state. In addition, beginning three years after
an association fails the QTL test, the association is prohibited from engaging
in any activity not permissible for a national bank and must repay any
outstanding advances from the FHLB as promptly as possible. On September 30,
1996, Congress enacted the Economic Growth and Paperwork Reduction Act of 1996
("Regulatory Paperwork Reduction Act"), which modified and expanded the
investment authority of federal savings associations under the QTL test. The
Regulatory Paperwork Reduction Act expanded the definition of "qualified thrift
investment" to include, without limit, education, small business, and credit
card loans, and removed the 10% limit on personal, family, or household loans
for purposes of the QTL test. The legislation also provides that a thrift meets
the QTL test if it qualifies as a domestic building and loan association under
the Internal Revenue Code. As of December 31, 1996, Astoria Federal maintained
its portfolio assets in qualified thrift investments in excess of 85% and had
more than 65% of its portfolio assets in qualified thrift investments for each
of the 12 months ending December 31, 1996. Therefore, Astoria Federal qualified
under the QTL test.
 
     Liquidity.  Astoria Federal is required to maintain an average daily
balance of liquid assets (cash, certain time deposits, bankers' acceptances,
specified United States Government, state or federal agency obligations, shares
of certain mutual funds and certain corporate debt securities and commercial
paper) equal to a monthly average of not less than a specified percentage of its
net withdrawable deposit accounts plus short-term borrowings. This liquidity
requirement may be changed from time to time by the OTS to any amount within the
range of 4% to 10% depending upon economic conditions and the savings flows of
member institutions, and is currently 5%. OTS regulations also require each
savings association to maintain an average daily balance of short-term liquid
assets at a specified percentage (currently 1%) of the total of its net
withdrawable deposit accounts and borrowings payable in one year or less.
Monetary penalties may be imposed for failure to meet these liquidity
requirements. Astoria Federal's liquidity and short-term liquidity ratios for
December 31, 1996 were 8.60% and 3.76%. Astoria Federal has never failed to meet
its liquidity requirements.
 
     Assessments.  Federally chartered savings associations are required by OTS
regulations to pay assessments to the OTS to fund the operations of the OTS. The
general assessment, paid on a semi-annual basis, is computed upon the federally
chartered savings association's total assets, including consolidated
subsidiaries, as reported in the association's latest quarterly thrift financial
report. The assessment recorded by Astoria Federal for the year ended December
31, 1996 totaled $917,200.
 
     Branching.  OTS regulations authorize federally chartered savings
associations to branch nationwide to the extent allowed by federal statute. This
permits federal savings and loan associations with interstate networks to
diversify more easily their loan portfolios and lines of business
geographically. The OTS' authority preempts any state law purporting to regulate
branching by federal savings associations. The branching powers afforded federal
savings associations are broader than the branching authority currently
available to national banks and state chartered institutions, which generally
lack the authority to branch outside their state of domicile. However, national
banks and state chartered banks and savings banks will have increased authority
under 1995 legislation to establish interstate branches beginning in June 1997.
 
HOLDING COMPANY REGULATION
 
     AFC is a non-diversified, unitary savings and loan holding company within
the meaning of the HOLA. As such, AFC is registered with the OTS and is subject
to the OTS regulations, examinations, supervision and reporting requirements. In
addition, the OTS has enforcement authority over AFC. Among other things, this
authority permits the OTS to restrict or prohibit activities that are determined
to be a serious risk to any of a holding company's subsidiaries which are
savings associations. Astoria Federal must notify the OTS at least 30
 
                                       85
<PAGE>   93
 
days before declaring any dividend to AFC. Such notification has been complied
with for each dividend declared in 1996 to AFC, for which Astoria Federal has
received OTS approval.
 
     Because AFC is a holding company, the rights of AFC to participate in any
distribution of assets of any subsidiary, including Astoria Federal, upon the
subsidiary's liquidation or reorganization or otherwise (and thus the ability of
AFC's stockholders to benefit indirectly from such distribution) would be
subject to the prior claims of creditors of that subsidiary, except to the
extent that AFC itself may be a creditor of that subsidiary with recognized
claims. Claims on AFC subsidiaries by creditors other than AFC will include
substantial obligations with respect to deposit liabilities and purchased funds.
 
     The HOLA prohibits a savings and loan holding company (directly or
indirectly) or through one or more subsidiaries from acquiring another savings
association or holding company thereof without prior written approval of the
OTS; acquiring or retaining, with certain exceptions, more than 5% of a
non-subsidiary savings association, a nonsubsidiary holding company, or a
non-subsidiary company engaged in activities other than those permitted by the
HOLA or acquiring or retaining control of an institution that is not federally
insured. In evaluating applications by holding companies to acquire savings
associations, the OTS must consider the financial and managerial resources and
future prospects of the company and institution involved, the effect of the
acquisition on the risk to the insurance funds, the convenience and needs of the
community and competitive factors.
 
     As a unitary savings and loan holding company, AFC generally is not
restricted under existing laws as to the types of business activities in which
it may engage; provided, that Astoria Federal continues to be a QTL. Upon any
non-supervisory acquisition by AFC of another savings association or savings
bank that meets the QTL test and is deemed to be a savings association by the
OTS, AFC would become a multiple savings and loan holding company (if the
acquired institution is held as a separate subsidiary) and would be subject to
extensive limitations on the types of business activities in which it could
engage. The HOLA limits the activities of a multiple savings and loan holding
company and its non-insured institution subsidiaries primarily to activities
permissible for bank holding companies under Section 4(c)(8) of the BHC Act,
subject to the prior approval of the OTS, and activities authorized by OTS
regulations, which activities include mortgage banking, consumer finance,
operation of a trust company, and certain types of securities brokerage
activities.
 
     The OTS is prohibited from approving any acquisition that would result in a
multiple savings and loan holding company controlling savings associations in
more than one state, subject to two exceptions: (i) the approval of interstate
supervisory acquisitions by savings and loan holding companies, and (ii) the
acquisition of a savings association in another state if the laws of the state
of the target savings association specifically permit such acquisitions.
Although the conditions imposed upon acquisitions in those states that have
enacted such legislation vary, many such statutes are of the "reciprocity" type
and a number are limited by regional restrictions, which require that the
acquiring holding company be located (as defined by the location of its
subsidiary savings associations) in a state within a defined geographic region
and that the state in which the acquiring holding company is located has enacted
reciprocal legislation allowing savings associations in the target state to
purchase savings associations in the acquiror's home state on terms no more
restrictive than those imposed by the target state on the acquiror. Some states
authorize acquisition by out-of-state holding companies only in supervisory
cases, and certain states do not authorize interstate acquisitions under any
circumstances.
 
     Under the Change in Bank Control Act, HOLA and 12 C.F.R. Part 574
promulgated thereunder, OTS approval (or, in certain cases, non-disapproval)
must be obtained before any person may acquire control of a savings and loan
holding company such as AFC. For such purposes, "person" includes an individual
or an entity, and security holdings of persons acting in concert are aggregated
for purposes of applying these provisions. Control is conclusively presumed to
exist if, among other things, a person acquires more than 25% of any class of
voting stock of a savings and loan holding company or controls in any manner the
election of a majority of the directors of the savings and loan holding company.
Control is rebuttably presumed to exist if, among other things, a person
acquires more than 10% of any class of voting stock (or 25% of any class of
stock) of a savings and loan holding company and is subject to any of certain
specified "control factors." The control factors relate to, among other matters,
the percentage of the debt and equity of the savings and loan
 
                                       86
<PAGE>   94
 
holding company owned by the person, agreements giving the person influence over
a material aspect of the operations of the savings and loan holding company and
the number of seats on the board of directors of the savings and loan holding
company held by the person or designees of the person. Subject to rebuttal, a
person also may be deemed to have control of a savings and loan holding company
if such person holds any combination of voting stock and revocable or
irrevocable proxies representing more than 25% of any class of voting stock of
the savings and loan holding company (excluding proxies held in connection with
a solicitation by, or in opposition to, a solicitation on behalf of management,
but including a solicitation in connection with the election of directors) and
the proxies would enable such person to: (i) elect one-third or more directors
of, (ii) cause the stockholders to approve the acquisition or reorganization of,
or (iii) exert a continuing influence on a material aspect of the business
operations of, an association or its holding company. OTS regulations provide an
application procedure to rebut the control presumptions. If the holders of the
AFC Series B Preferred Stock become entitled to vote for the election of
directors because dividends are in arrears, such series may then be deemed a
separate "class of voting stock" for purposes of the foregoing.

                                   STATEMENTS
                      DECEMBER 31, 1996 AND MARCH 31, 1997
 
     (A) Basis of Presentation
 
     The Unaudited Pro Forma Combined Condensed Consolidated Statement of
Financial Condition of AFC and subsidiary and GNYSB and subsidiaries at March
31, 1997 has been prepared as if the Merger had been consummated on that date.
The Unaudited Pro Forma Combined Condensed Consolidated Statements of Operations
for the year ended December 31, 1996 and the three months ended March 31, 1997
were prepared as if the Merger had been consummated on January 1, 1996. The
unaudited pro forma combined condensed consolidated financial statements are
based on the historical financial statements of AFC and GNYSB after giving
effect to the Merger under the purchase method of accounting and the assumptions
and adjustments in the notes that follow.
 
     Assumptions relating to the pro forma adjustments set forth in the
unaudited pro forma combined condensed consolidated financial statements are
summarized as follows:
 
          (i) Estimated fair values -- Estimated fair values for securities
     held-to-maturity, loans, deposits and borrowings were obtained from GNYSB's
     1996 Annual Report to Shareholders -- Footnote number 17 of "Notes to
     Consolidated Financial Statements" -- Fair Value of Financial Instruments.
     The resulting net discount/premium on securities held-to-maturity and
     loans, respectively, for purposes of these pro forma financial statements,
     is being accreted/amortized to interest income on a straight-line basis
     over four and ten years, respectively. The actual discount/premium will be
     accreted/amortized to interest income to produce a constant yield to
     maturity. The resulting net premium and discount on deposits and
     borrowings, respectively, is being amortized/accreted into interest expense
     on a straight-line basis over their remaining estimated lives of five
     years.
 
          (ii) Income taxes -- a net deferred tax asset was recorded equal to
     the deferred tax consequences associated with the differences between the
     tax basis and book basis of the assets acquired and liabilities assumed,
     using a statutory tax rate of 43.03%.
 
     (B) The Merger Agreement requires GNYSB at the written request of AFC to
modify and change certain of its policies and practices, including loan policies
and practices, before the Effective Time so as to be consistent on a mutually
satisfactory basis with those of Astoria Federal subject to compliance with
generally accepted accounting principles and all applicable laws and
regulations. GNYSB is not obligated to take any such action until after the date
on which all required regulatory approvals and stockholder approvals are
received and after receipt of written confirmation from AFC that it is not aware
of any fact or circumstance that would prevent completion of the Merger. AFC has
advised GNYSB that it expects to make such a request and that it currently
expects that compliance with such requirement will result in an additional
provision for loan losses of $19,500,000. Differences in policies and practices
of GNYSB and AFC which give rise to this additional provision include, but are
not limited to, evaluation of current and future economic trends, estimation of
fair value, particularly for collateral dependent loans, designation of
non-accrual loans and underwriting standards. A corresponding deferred tax asset
of $8,951,000 was recorded in other assets using GNYSB's historical statutory
tax rate of 45.9%. The provision is not reflected in the Unaudited Pro Forma
Combined Condensed Consolidated Statements of Operations as the statements are
prepared as if the Merger had occurred on January 1, 1996. The provision is a
non-recurring charge which would have been recorded by GNYSB prior to the Merger
assuming all regulatory and stockholder approvals were obtained, AFC made a
written request and the Merger was consummated. The following table reconciles
the adjustments to the historical GNYSB and subsidiaries Consolidated Statement
of Condition at March 31, 1997 with the presentation of the Unaudited Pro Forma
Combined Condensed Consolidated Statement of Financial Condition as of March 31,
1997.

                        DESCRIPTION OF AFC CAPITAL STOCK
 
GENERAL
 
     AFC is authorized to issue 70,000,000 shares of Common Stock having a par
value of $0.01 per share and 5,000,000 shares of Preferred Stock having a par
value of $0.01 per share (the "AFC Preferred Stock"). If AFC's stockholders
approve the Certificate Amendment, upon consummation of the Merger, AFC
Preferred Stock will have a par value of $1.00 per share. As of the AFC Record
Date, there were 20,972,257 shares of AFC Common Stock issued and outstanding
and no shares of AFC Preferred Stock issued and outstanding. Each share of the
AFC Common Stock has the same relative rights as, and is identical in all
respects with, each other share of AFC Common Stock. The AFC Board has the power
from time to time to issue additional shares of AFC Common Stock or preferred
stock authorized by AFC's Certificate of Incorporation without obtaining
approval of AFC's stockholders. The rights, qualifications, limitations and
restrictions on each series of preferred stock issued will be determined by the
AFC Board and approved as required by the DGCL or otherwise, at the time of
issuance and may include, among other things, rights in liquidation, rights to
participating dividends, voting and convertibility to AFC Common Stock. The
following descriptions of AFC capital stock are qualified in their entirety by
reference to AFC's Certificate of Incorporation. See "CERTIFICATE AMENDMENT."
 
AFC COMMON STOCK
 
     Dividends.  AFC can pay dividends out of statutory surplus or from certain
net profits if, as, and when declared by the AFC Board. The payment of dividends
by AFC is subject to limitations that are imposed by law and applicable
regulations. The holders of AFC Common Stock are entitled to receive and share
equally in such dividends as may be declared by the AFC Board out of funds
legally available therefor. Holders of AFC Preferred Stock will have a priority
over the holders of AFC Common Stock with respect to dividends. See "-- AFC
Preferred Stock -- AFC Series B Preferred Stock -- Noncumulative Dividends," and
"CERTAIN REGULATORY CONSIDERATIONS -- Restrictions on Payment of Dividends."
 
     Voting Rights.  The holders of AFC Common Stock possess exclusive voting
rights in AFC. Such holders elect the AFC Board and act on such other matters as
are required to be presented to them under the DGCL or AFC's Certificate of
Incorporation or as are otherwise presented to them by the AFC Board. Except as
discussed in "Limitation on Voting Rights," each holder of AFC Common Stock is
entitled to one vote per share of AFC Common Stock and will not have any right
to cumulate votes in the election of directors. Holders of AFC Preferred Stock
will not have voting rights except in certain limited circumstances although the
AFC Board may provide voting rights for any newly created series of AFC
Preferred Stock that may be issued in the future. See "-- AFC Preferred
Stock -- AFC Junior Preferred Stock" and " -- AFC Preferred Stock -- AFC Series
B Preferred Stock -- Voting Rights."
 
     Limitation on Voting Rights.  AFC's Certificate of Incorporation provides
that in no event shall any record owner of any outstanding AFC Common Stock that
is beneficially owned, directly or indirectly, by a person who beneficially owns
in excess of 10% of the then outstanding shares of AFC Common Stock (the
"Limit") be entitled or permitted to any vote with respect to the shares held in
excess of the Limit. Beneficial ownership is determined pursuant to Rule 13d-3
of the General Rules and Regulations promulgated pursuant to the Exchange Act,
and includes shares beneficially owned by such person or any of his affiliates
(as defined in AFC's Certificate of Incorporation), shares that such person or
his affiliates have the right to acquire upon the exercise of conversion rights
or options, and shares as to which such person and his affiliates have or share
investment or voting power, but shall not include shares beneficially owned by
Astoria Federal's ESOP or, in the case of directors or officers of Astoria
Federal or AFC, shares beneficially owned by any other such director or officer
or shares that are subject to a publicly solicited revocable proxy and that are
not otherwise beneficially owned, or deemed by AFC to be beneficially owned, by
such person and his affiliates. AFC's Certificate of Incorporation further
provides that such provision limiting voting rights only may be amended upon the
vote of 80% of the outstanding shares of voting stock.
 
                                       96
<PAGE>   104
 
     Liquidation Rights.  In the event of any liquidation, dissolution, or
winding up of Astoria Federal, AFC, as a holder of Astoria Federal's capital
stock, would be entitled to receive, after payment or provision for payment of
all debts and liabilities of Astoria Federal (including all deposit accounts and
accrued interest thereon) and after distribution of the balance in the special
liquidation accounts established for the benefit of certain account holders of
Astoria Federal in connection with its conversion to stock form and for the
benefit of certain account holders of Fidelity in connection with its conversion
to stock form, all assets of Astoria Federal available for distribution. In the
event of liquidation, dissolution, or winding up of AFC, the holders of AFC
Common Stock would be entitled to receive, after payment or provision for
payment of all its debts and liabilities, all of the assets of AFC available for
distribution. Holders of AFC Preferred Stock will have a priority over the
holders of AFC Common Stock in the event of liquidation or dissolution.
 
     Preemptive Rights.  Holders of the AFC Common Stock are not entitled to
preemptive rights with respect to any shares which may be issued.
 
     Issuance of Stock.  In certain instances, the issuance of authorized but
unissued shares of AFC Common Stock or AFC Preferred Stock may have an
anti-takeover effect. The authority of the AFC Board to issue AFC Preferred
Stock with rights and privileges, including voting rights, as it may deem
appropriate, may enable the AFC Board to prevent a change of control despite a
shift in ownership of AFC Common Stock. In addition, the AFC Board's authority
to issue additional shares of AFC Common Stock may help deter or delay a change
of control by increasing the number of shares needed to gain control.
 
     Certain Anti-takeover Provisions.  AFC's Certificate of Incorporation and
Bylaws contain a number of provisions that may be deemed to have the effect of
discouraging or delaying attempts to gain control of AFC, including provisions
(i) classifying the AFC Board into three classes with each class to serve for
three years with one class being elected annually; (ii) authorizing the AFC
Board the exclusive power to fix from time to time the size of the AFC Board;
(iii) authorizing a majority vote of the AFC Board then in office to fill
vacancies in the AFC Board; (iv) providing that the directors may be removed
only for cause and only by the affirmative vote of at least 80% of the shares
entitled to be voted in the election of directors; (v) providing that any action
required or permitted to be taken by the stockholders of AFC may not be effected
by a written consent by such stockholders; (vi) allowing the AFC Board to give
due consideration to constituencies other than AFC's stockholders in evaluating
acquisition or merger proposals; (vii) providing that certain of the foregoing
provisions only may be amended by the affirmative vote of at least 80% of the
outstanding stock entitled to vote or a majority vote of the AFC Board; and
(viii) setting forth specific conditions under which: (a) business may be
transacted at an annual meeting of stockholders; and (b) persons may be
nominated for election as directors of AFC at an annual meeting of stockholders.
 
     The foregoing provisions could impede a change of control of AFC. In
particular, classification of the AFC Board has the effect of decreasing the
number of directors that could be elected in a single year by any person who
seeks to elect its designees to a majority of the seats on the AFC Board.
Furthermore, allowing the AFC Board to consider nonstockholder constituencies
may have the effect of increasing the AFC Board's discretion to reject
acquisition or merger proposals.
 
AFC PREFERRED STOCK
 
     As of the AFC Record Date, no shares of AFC Preferred Stock have been
issued by AFC. AFC Preferred Stock may be issued with such preferences and
designations as the AFC Board may determine from time to time. The AFC Board may
issue, without stockholder approval, AFC Preferred Stock with voting, dividend,
liquidation, and conversion rights that could dilute the voting strength of the
holders of AFC Common Stock and may assist AFC's management in impeding an
unfriendly takeover or an attempted change in control.
 
     Although AFC has no arrangements, understandings, or plans at the present
time for the issuance or use of the shares of undesignated preferred stock (the
"AFC Undesignated Preferred Stock") authorized, the AFC Board believes that the
availability of such shares will provide AFC and Astoria Federal with increased
flexibility in structuring possible future financing and acquisitions and in
meeting other corporate needs that may arise. In the event of a proposed merger,
tender offer, or other attempt to gain control of AFC of which
 
                                       97
<PAGE>   105
 
AFC management does not approve, the AFC Board may be able to authorize the
issuance of one or more series of AFC Preferred Stock with rights and
preferences that could impede the completion of such a hostile transaction. The
issuance of AFC Preferred Stock, therefore, may deter future takeover attempts.
The AFC Board does not intend to issue any AFC Preferred Stock except on terms
that it deems to be in the best interest of both Astoria Federal's and AFC's
then existing stockholders.
 
     AFC Junior Preferred Stock.  AFC's Certificate of Designations with respect
to the AFC Junior Preferred Stock authorizes the issuance of AFC Series A Junior
Participating Preferred Stock, par value $.01 per share ("AFC Junior Preferred
Stock"). AFC Junior Preferred Stock is only issuable in connection with AFC's
Rights Plan. See "COMPARISON OF CERTAIN RIGHTS OF STOCKHOLDERS -- Rights
Plans -- AFC." When issued, the AFC Junior Preferred Stock will rank junior to
all other series of AFC's preferred stock as to the payment of dividends and the
distribution of assets, unless the terms of any such series provide otherwise.
The AFC Junior Preferred Stock will rank junior to the AFC Series B Preferred
Stock.
 
     Dividends on the AFC Junior Preferred Stock will be cumulative to the
greater of (i) $1.00 or (ii) subject to adjustment, 100 times the aggregate per
share amount of all cash dividends declared on AFC Common Stock, and 100 times
the aggregate per share amount of all non-cash dividends or other distributions
declared on AFC Common Stock other than a dividend payable in shares of AFC
Common Stock or a subdivision of the outstanding shares of AFC Common Stock.
 
     The holders of AFC Junior Preferred Stock will have no voting rights except
as required by law.
 
     The AFC Junior Preferred Stock has preference over the AFC Common Stock
with respect to the distribution of assets in the event of a liquidation,
dissolution, or winding up of AFC. The liquidation preference of the AFC Junior
Preferred Stock is $100.00 per share, plus an amount equal to accrued and unpaid
dividends and distributions.
 
     If AFC enters into any consolidation, merger, combination or other
transaction in which shares of AFC Common Stock are exchanged for or changed
into other stock or securities, cash and/or any other property, then the shares
of AFC Junior Preferred Stock will at the same time be similarly exchangeable or
changeable in an amount equal to 100 times the aggregate amount of consideration
received by the holders of AFC Common Stock. Holders of the AFC Junior Preferred
Stock are not entitled to preemptive rights with respect to any shares of AFC
that may be issued.
 
     AFC Series B Preferred Stock.  AFC's Certificate of Designations with
respect to AFC Series B Preferred Stock authorizes AFC to issue up to 2,000,000
shares of AFC Series B Preferred Stock. Except for its issuer, the AFC Series B
Preferred Stock will have terms that are substantially identical to and no less
favorable than the terms of the GNYSB Series B Preferred Stock. The AFC Series B
Preferred Stock, upon issuance in connection with the Merger, will be fully paid
and nonassessable. The holders of AFC Series B Preferred Stock will have no
preemptive rights. The rights of the holders of AFC Series B Preferred Stock
will be subordinate to the rights of AFC's general creditors. The AFC Series B
Preferred Stock will not be subject to any mandatory redemption, sinking fund,
or other obligation of AFC to redeem or retire the AFC Series B Preferred Stock.
 
        Rank.  The AFC Series B Preferred Stock will rank prior to the AFC
Common Stock and to all other classes and series of equity securities of AFC
(collectively, "Junior Stock"), now or hereafter authorized, other than Parity
Stock and Senior Stock (as hereinafter defined) with respect to dividend rights
and rights upon the voluntary or involuntary liquidation, dissolution or winding
up of AFC. "Parity Stock" means any class or series of equity securities of AFC
expressly designated as ranking, with respect to dividend rights and rights upon
the voluntary or involuntary liquidation, dissolution or winding up of AFC, on a
parity with the AFC Series B Preferred Stock. "Senior Stock" means any class or
series of equity securities of AFC expressly designated as ranking, with respect
to dividend rights and rights upon the liquidation, dissolution or winding up of
AFC, as senior to the AFC Series B Preferred Stock. AFC Junior Preferred Stock
is designated as Junior Stock.

<PAGE>   106
 
        Noncumulative Dividends.  Holders of shares of AFC Series B Preferred
Stock will be entitled to receive, when, as and if declared by the AFC Board or
a duly authorized committee thereof, out of funds of AFC legally available for
payment therefor, noncumulative cash dividends at an annual rate of 12% of the
$25.00 liquidation preference per share ($3.00 per share per annum), and no
more. Such noncumulative dividends, payable only in cash, may be declared and
payable quarterly in equal amounts in arrears, at the rate of $0.75 per share
per quarter, to be paid on January 15, April 15, July 15 and October 15 of each
year or, if such day is not a business day, on the next business day (each such
date, a "Series B Dividend Payment Date"). Each declared dividend shall be
payable to holders of record of the AFC Series B Preferred Stock as they appear
on the stock books of AFC (or of any transfer agent for the AFC Series B
Preferred Stock) at the close of business on such record dates, not more than
fifty (50) calendar days nor less than ten (10) calendar days preceding the
Series B Dividend Payment Date therefor, as determined by the AFC Board (each
such date, a "Record Date"). The initial period for which dividends shall be
paid (the "Initial Dividend Period") shall commence on the last "Dividend Period
Commencement Date" (as defined below) that occurred under the GNYSB Series B
Preferred Stock and shall end on and include the date next preceding the first
Dividend Period Commencement Date to occur after the Merger. A full dividend
shall be paid for the Initial Dividend Period. Thereafter, quarterly dividend
periods (each, a "Dividend Period") shall commence on and include March 1, June
1, September 1 and December 1 of each year (each such date, a "Dividend Period
Commencement Date") and shall end on and include the date next preceding the
Dividend Period Commencement Date of the following Dividend Period.
 
     The right of holders of AFC Series B Preferred Stock to receive dividends
is noncumulative. Accordingly, if the AFC Board fails to declare a dividend
payable on a Series B Dividend Payment Date, then holders of the AFC Series B
Preferred Stock will have no right to receive a dividend in respect of the
Dividend Period ending on such Series B Dividend Payment Date, and AFC will have
no obligation to pay the dividend accrued for such period, whether or not
dividends are declared and payable on any future Series B Dividend Payment
Dates.
 
     No full dividends may be declared or paid or set apart for payment on any
Parity Stock for any dividend period unless full dividends on the AFC Series B
Preferred Stock for the Dividend Period ending on the same day as such dividend
period will have been or contemporaneously are declared and paid or declared and
a sum sufficient for the payment thereof is set apart for such payment. If, with
respect to any Dividend Period, dividends are not paid in full (or declared and
a sum sufficient for such full payment is not so set apart) on the AFC Series B
Preferred Stock and any other Parity Stock, dividends declared on the AFC Series
B Preferred Stock and other Parity Stock shall only be declared pro rata, such
that the amount of dividends declared per share on the AFC Series B Preferred
Stock and other Parity Stock shall bear to each other the same ratio that, at
the time of such declaration, all accrued and payable but unpaid dividends for
such Dividend Period per share on shares of the AFC Series B Preferred Stock
(which shall not include any accumulation in respect of unpaid dividends for
prior Dividend Periods) and other Parity Stock bear to each other. Full
dividends on the AFC Series B Preferred Stock must be declared and paid or set
apart for payment for the most recently concluded Dividend Period before (i) any
dividends (other than dividends payable in AFC Common Stock or other Junior
Stock) may be declared or paid or set aside for payment, or other distribution
made upon the AFC Common Stock or on any other Junior Stock or (ii) any Junior
Stock is redeemed (or any monies are paid to or made available for a sinking
fund for the redemption of any shares of any such Junior Stock) or any Junior
Stock is purchased or otherwise acquired by AFC for any consideration except by
conversion into or exchange for Junior Stock.
 
     There can be no assurance that any dividend on the AFC Series B Preferred
Stock will be declared or, if so, in what amount. Further, there can be no
assurance that dividends, once declared, will continue for any future Dividend
Period. The declaration and payment of future dividends on the AFC Series B
Preferred Stock will be subject to business conditions, the earnings and
financial condition of AFC and the judgment of the AFC Board. Dividends also
will be affected by dividend restrictions and limitations imposed by the DGCL
and by the ability of Astoria Federal to pay dividends to AFC. See "CERTAIN
REGULATORY CONSIDERATIONS -- Restrictions on Payment of Dividends."

<PAGE>   107
 
        Liquidation Preference.  In the event of any liquidation, dissolution or
winding up of AFC, voluntary or involuntary, the holders of AFC Series B
Preferred Stock will be entitled to receive out of the assets of AFC available
for distribution to stockholders, before any distribution of assets is made to
the holders of AFC Common Stock or other Junior Stock, liquidating distributions
in the amount of $25.00 per share, plus an amount per share equal to all
accrued, undeclared and unpaid dividends thereon from the Dividend Period
Commencement Date next preceding the date fixed for such liquidation,
dissolution or winding up; provided, however, that the holders of AFC Series B
Preferred Stock and any Parity Stock will be entitled to such liquidating
distributions only after payment in full of liquidating distributions of holders
of shares of any Senior Stock. If, upon any voluntary or involuntary
liquidation, dissolution or winding up of AFC, the amounts payable with respect
to the AFC Series B Preferred Stock and any Parity Stock are not sufficient to
satisfy the full liquidation rights of all the outstanding shares thereof, the
holders of the AFC Series B Preferred Stock and of such Parity Stock will share
ratably in any such distribution of assets of AFC in proportion to the full
respective preferential amounts to which they are entitled (which, in the case
of Parity Stock, may include accumulated dividends). After payment of the full
amount of the liquidating distribution to which they are entitled, the holders
of AFC Series B Preferred Stock will not be entitled to any further
participation in any distribution of assets of AFC. All distributions made with
respect to the AFC Series B Preferred Stock in connection with such liquidation,
dissolution or winding up of AFC will be made pro rata to the holders entitled
thereto. Neither the merger or consolidation of AFC with or into any other
entity, nor the merger or consolidation of any other entity with or into AFC,
nor the sale, transfer or lease of all or any portion of the assets of AFC, will
be deemed to be a liquidation, dissolution or winding up of AFC.
 
        Optional Redemption.  The AFC Series B Preferred Stock will not be
redeemable before October 1, 2003. On or after October 1, 2003, the AFC Series B
Preferred Stock is redeemable at the option of AFC, in whole or in part, at any
time and from time to time, at the redemption prices set forth below in cash,
plus in each case, an amount in cash equal to all accrued and unpaid dividends
thereon, whether or not declared, from the Dividend Period Commencement Date
next preceding the date fixed for redemption (the "Redemption Date") to, but
excluding, the Redemption Date (without accumulation of unpaid dividends for
prior Dividend Periods):

     If fewer than all the outstanding shares of the AFC Series B Preferred
Stock are to be redeemed, AFC will select those to be redeemed pro rata, by lot,
or by such other method as the AFC Board, in its sole discretion, determines to
be equitable.
 
     Notice of any redemption shall be given by first-class mail, postage
prepaid, mailed at least twenty (20) days but not more than sixty (60) days
prior to the Redemption Date to each holder of record of AFC Series B Preferred
Stock to be redeemed at such holder's address as the same shall appear on the
stock books of AFC (or of any transfer agent for the AFC Series B Preferred
Stock). If on or before the Redemption Date specified in such notice, all funds
necessary for such redemption have been set aside by AFC, separate and apart
from its other funds, in trust for the account of holders of shares of AFC
Series B Preferred Stock to be redeemed, then, on and after the Redemption Date,
notwithstanding that any certificates for shares of AFC Series B Preferred Stock
so called for redemption shall not have been surrendered for cancellation, the
shares of AFC Series B Preferred Stock so called for redemption will be deemed
to be no longer outstanding and the holders of such shares will cease to be
stockholders of AFC and shall have no voting or other rights with respect to
such shares, except for the right to receive out of the funds so set aside in
trust the amount payable on redemption thereof, without interest, upon surrender
of their certificates.

        Conversion Rights.  The holders of shares of AFC Series B Preferred
Stock will not have any rights to convert such shares into shares of any other
class or series of capital stock or into any other securities of, or any
interest in, AFC.
 
        Voting Rights.  Except as indicated below and except as required by
applicable law, the holders of the AFC Series B Preferred Stock will not be
entitled to vote for any purpose.
 
     As long as any shares of the AFC Series B Preferred Stock remain
outstanding, unless the vote of the holders of a greater number of such shares
is required by law, the affirmative vote of the holders of at least two-thirds
of the votes entitled to be cast with respect to the then-outstanding shares of
the AFC Series B Preferred Stock, voting as a class, will be necessary to (i)
amend, alter, or repeal or otherwise change any provision of the AFC's
Certificate of Incorporation (including any such amendment, alteration, repeal
or change effected by any merger or consolidation in which AFC is the surviving
or resulting corporation) if such amendment, alteration, repeal, or change would
materially and adversely affect the rights, preferences, powers, or privileges
of the AFC Series B Preferred Stock, or (ii) authorize, create, or issue or
increase the authorized or issued amount of any class or series of Senior Stock
or any warrants, options, or other rights convertible into or exchangeable for
any class or series of Senior Stock. The creation or issuance of Parity Stock or
Junior Stock, or the distribution of assets upon a voluntary or involuntary
liquidation, dissolution or winding up of AFC, or a merger, consolidation,
reorganization, or other business combination in which AFC is not the surviving
or resulting corporation, or an amendment that substitutes the surviving or
resulting corporation in a merger or consolidation for AFC or which increases
the number of shares of preferred stock which AFC is authorized to issue, shall
not be deemed to be a material and adverse change to the rights, preferences,
powers, or privileges of the AFC Series B Preferred Stock requiring a vote of
the holders thereof. No vote of the AFC Series B Preferred Stock will be
required if the AFC Series B Preferred Stock is to be redeemed in whole on a
Redemption Date occurring on or prior to the date of occurrence of any event
otherwise requiring a class vote by the AFC Series B Preferred Stock.
 
     If six (6) full quarterly dividends on the AFC Series B Preferred Stock,
whether or not consecutive, are not paid, the holders of AFC Series B Preferred
Stock and the holders of any other class or series of Parity Stock as to which
the payment of dividends is in arrears and unpaid in an aggregate amount equal
to or exceeding the amount of dividends payable for six (6) quarterly dividend
periods (or if dividends are payable other than on a quarterly basis, the number
of dividend periods, whether or not consecutive, containing in the aggregate not
less than five hundred forty (540) calendar days) and upon which by its terms
the same right to elect two (2) directors has been conferred and is exercisable
(the "Voting Parity Stock"), will have the exclusive right, voting together as a
single class, to elect two directors for newly created directorships of AFC,
each director to be in addition to the number of directors constituting the AFC
Board immediately prior to the accrual of such right (the remaining directors to
be elected by the other class or classes of stock entitled to vote therefor), at
each meeting of stockholders duly held for the purpose of electing directors. At
any time when the right to elect such directors is vested, AFC may, and upon the
written request of the holders of record of not less than 20% of the total
number of shares of the AFC Series B Preferred Stock and such Voting Parity
Stock then outstanding will, call a special meeting of the holders of such
shares to fill such newly-created directorships. The right of holders of AFC
Series B Preferred Stock to elect directors will continue until dividends on the
AFC Series B Preferred Stock have been paid for four (4) consecutive Dividend
Periods, at which time such voting rights of the holders of the AFC Series B
Preferred Stock and the Voting Parity Stock will, without further action,
terminate, subject to revesting in the event of each and every subsequent
failure of AFC to pay such dividends for the requisite number of periods as
described above; provided, however, that if, at the time of termination of the
election right of the holders of the AFC Series B Preferred Stock, there will be
outstanding any Voting Parity Stock having similar voting rights which remain in
effect, the term of any directors elected by the holders of the AFC Series B
Preferred Stock and such Voting Parity Stock shall continue until such time as
the voting right of the holders of such Voting Parity Stock shall terminate by
its terms.
 
     The term of office of all directors elected by the holders of the AFC
Series B Preferred Stock and the Voting Parity Stock in office at any time when
the aforesaid voting right is vested in such holders will terminate upon the
election of their successors at any meeting of stockholders for the purpose of
electing
 
                                       101
<PAGE>   109
 
directors; provided, however, that, without further action and unless otherwise
required by law, any directors who shall have been elected by the holders of the
AFC Series B Preferred Stock and the Voting Parity Stock as provided herein may
be removed at any time, either with or without cause by the affirmative vote of
the holders of record of a majority of the outstanding shares of the AFC Series
B Preferred Stock and the Voting Parity Stock, voting together as a single
class. Upon termination of the aforesaid voting right in accordance with the
foregoing provisions, the term of office of all directors elected by the holders
of the AFC Series B Preferred Stock and the Voting Parity Stock pursuant thereto
then in office will, without further action, terminate unless otherwise required
by law. Upon such termination, the number of directors constituting AFC's Board
of Directors will, without further action, be reduced by two (2), subject always
to the increase of the number of directors pursuant to the foregoing provisions
in the case of the future right of such holders of the AFC Series B Preferred
Stock and the Voting Parity Stock to elect directors as provided above.
 
     Unless otherwise required by law, in the case of any vacancy occurring
among the directors so elected, the remaining director who shall have been so
elected may appoint a successor to hold office for the unexpired term of the
director whose place shall be vacant, and if all directors so elected by the
holders of the AFC Series B Preferred Stock and the Voting Parity Stock shall
cease to serve as directors before their term shall expire, the holders of the
AFC Series B Preferred Stock and the Voting Parity Stock then outstanding may,
at a meeting of such holders duly held, elect successors to hold office for the
unexpired terms of the directors whose places shall be vacant.
 
     The directors elected by the holders of the AFC Series B Preferred Stock
and the Voting Parity Stock in accordance with the foregoing provisions will be
entitled to one vote per director on any matter.
 
     AFC's Certificate of Incorporation provides that the AFC Board will be
divided into three (3) classes. AFC's Certificate of Designations with respect
to the AFC Series B Preferred Stock also provides that the directors to be
elected by the AFC Series B Preferred Stock and the Voting Parity Stock, voting
together as a class, will not become members of the three (3) classes of
directors otherwise required by AFC's Certificate of Incorporation. AFC's
Certificate of Incorporation provides that if for any reason the holders of the
AFC Series B Preferred Stock and the Voting Parity Stock would not be able to
elect the specified number of directors at the next annual meeting of
stockholders in the manner described above, AFC will use its best efforts to
take all actions necessary to permit the full exercise of such voting rights
which will include, if necessary, taking action to increase the authorized
number of directors standing for election at such next annual meeting of
stockholders or seeking to amend, alter or change AFC's Certificate of
Incorporation and Bylaws. If such directors were required by law to be
classified, then such directors could not be removed from office except for
cause and then only with the vote of 80% of the votes eligible to be cast, and
any vacancies would be required to be filled by a majority of the directors then
in office.
 
     In connection with any matter on which holders of the AFC Series B
Preferred Stock are entitled to vote as one class or otherwise pursuant to law
or the provisions of AFC's Certificate of Incorporation, including, without
limitation, the election of directors as set forth above, each holder of the AFC
Series B Preferred Stock will be entitled to one vote for each share of the AFC
Series B Preferred Stock held by such holder.
 
          No Other Rights.  The shares of AFC Series B Preferred Stock will not
have any preferences, voting powers or relative, participating, optional or
other special rights except as set forth above and in AFC's Certificate of
Incorporation or as otherwise required by law.

                  COMPARISON OF CERTAIN RIGHTS OF STOCKHOLDERS
 
     GNYSB is a New York State-chartered capital stock savings bank subject to
the provisions of the NYBL. AFC is a Delaware corporation subject to the
provisions of the DGCL. At the Effective Time, stockholders of GNYSB whose
rights are governed by the GNYSB Restated Organization Certificate, the GNYSB
Bylaws and the NYBL and who are allocated stock under the exchange procedures
set forth herein, will, upon consummation of the Merger, become stockholders of
AFC, and their rights as stockholders will be determined by AFC's Certificate of
Incorporation, AFC's Bylaws, and the DGCL. The terms, designations, preferences,
limitations, privileges, and rights of the holders of AFC Series B Preferred
Stock under AFC's Certificate of Incorporation and AFC's Bylaws will be
substantially identical to those of GNYSB Series B Preferred Stock under GNYSB's
Restated Organization Certificate and GNYSB's Bylaws.
 
     The following is a summary of the material differences in the rights of
stockholders of GNYSB under GNYSB's Restated Organization Certificate, GNYSB's
Bylaws and the NYBL on the one hand, and the rights of stockholders of AFC under
AFC's Certificate of Incorporation, AFC's Bylaws and the DGCL, on the other
hand. The following discussion does not purport to be a complete discussion of,
and is qualified in its entirety by reference to, the governing laws, GNYSB's
Restated Organization Certificate, GNYSB's Bylaws, AFC's Certificate of
Incorporation and AFC's Bylaws.
 
SPECIAL MEETINGS OF STOCKHOLDERS
 
     AFC.  Under AFC's Bylaws, special meetings of AFC stockholders may be
called only by the AFC Board pursuant to a resolution adopted by a majority of
the total number of AFC directors that AFC would have if there were no vacancies
on the AFC Board.
 
     GNYSB.  GNYSB's Bylaws provide that special meetings of GNYSB stockholders,
for any purpose, may be called at any time by the Chairman, the President, or by
resolution of at least three-fourths of the GNYSB Board and must be called by
the Secretary upon the written request of the holders of record of three-fourths
of all the outstanding voting stock of GNYSB.
 
STOCKHOLDER ACTION BY WRITTEN CONSENT
 
     AFC.  AFC's Certificate of Incorporation does not permit any stockholder
action by written consent.
 
     GNYSB.  GNYSB's Restated Organization Certificate provides that whenever
GNYSB stockholders are required or permitted to take any action by vote at any
annual or special meeting, such action may be taken without a meeting upon
written consent, setting forth the action so taken, signed by the holders of all
outstanding shares of GNYSB stock entitled to vote thereon.
 
AMENDMENT OF CERTIFICATE OF INCORPORATION/ORGANIZATION CERTIFICATE
 
     AFC.  The DGCL provides that a corporation may amend its certificate of
incorporation by a majority vote of the outstanding stock entitled to vote
thereon, unless the certificate of incorporation provides for a higher vote.
AFC's Certificate of Incorporation requires the affirmative vote of the holders
of at least 80% of the voting power of all of the then-outstanding shares of the
capital stock of AFC entitled to vote generally in the election of AFC's
directors, voting together as a single class, to amend or repeal the provisions
of AFC's Certificate of Incorporation regarding: (i) amendments to AFC's
Certificate of Incorporation, (ii) beneficial ownership limitations on AFC
Common Stock, (iii) actions by stockholders by written consent, (iv) staggered
board of directors and the ability to fill vacancies on the AFC Board, (v)
removal of directors, (vi) stockholder special meetings, (vii) higher vote
requirements for certain actions, and (viii) director and officer
indemnification.
 
     GNYSB.  The NYBL provides that a stock form savings bank may amend its
organization certificate by a vote of the holders of a majority all outstanding
shares entitled to vote thereon at a meeting of stockholders unless the
organization certificate provides for a higher vote. GNYSB's Restated
Organization Certificate provides that the affirmative vote of at least 66 2/3%
of the total votes eligible to be cast by the holders of all outstanding shares
of GNYSB's capital stock entitled to vote thereon is required to amend, repeal
or adopt any
 
                                       103
<PAGE>   111
 
provisions inconsistent with the provisions of GNYSB's Restated Organization
Certificate regarding: (i) the GNYSB Board, (ii) actions by stockholders by
written consent, and (iii) certain amendments to GNYSB's Restated Organization
Certificate or Bylaws.
 
LIMITATION OF DIRECTOR AND OFFICER LIABILITY
 
     AFC.  Section 102(b)(7) of the DGCL permits the inclusion of a provision in
the certificate of incorporation of a Delaware corporation which eliminates or
limits the personal liability of a director of such corporation to the
corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, provided that such provision does not eliminate or limit the
liability of a director (i) for any breach of the director's duty of loyalty to
the corporation or its stockholders; (ii) for acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law;
(iii) for a breach of the DGCL provision relating to unlawful payment of
dividends or redemptions; or (iv) for any transaction from which the director
derived an improper personal benefit. AFC's Certificate of Incorporation
contains a provision so eliminating the liability of AFC directors to AFC or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except to the extent such exemption is not permitted under the DGCL. Such
provision absolves AFC directors from liability for monetary damages to AFC or
AFC's stockholders for breaches of their duty of due care, even if it involved
gross negligence, unless the conduct falls within one of the statutory
limitations.
 
     GNYSB.  There is no analogous provision in GNYSB's Restated Organization
Certificate as such a provision is not permitted under the NYBL.
 
INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     AFC.  Under Section 145 of the DGCL, a Delaware corporation may indemnify
fully its directors, officers, employees, and agents if such persons have acted
in good faith and in a manner that such persons reasonably believed was in, or
not opposed to, the best interests of the corporation. A Delaware corporation
also may indemnify fully such individuals with respect to criminal actions or
proceedings, provided that such individual had no reasonable cause to believe
such conduct was unlawful. AFC's Certificate of Incorporation provides that AFC
shall indemnify its directors, officers, employees, and agents to the fullest
extent authorized by the DGCL against all expense, liability and loss reasonably
incurred or suffered by such indemnitee in connection therewith; provided,
however, that except as provided in AFC's Certificate of Incorporation with
respect to proceedings to enforce rights to indemnification, AFC shall indemnify
any such indemnitee in connection with a proceeding initiated by such indemnitee
only if such proceeding was authorized by the AFC Board. AFC's Certificate of
Incorporation further permits AFC to maintain insurance on behalf of any
director, officer, employee, or agent of AFC.
 
     GNYSB.  Section 7019 of the NYBL permits indemnification of directors and
officers (but not employees) if such person acted in good faith for a purpose
that he reasonably believed to be in the best interests of the corporation, and
in criminal actions or proceedings, in addition, had no reasonable cause to
believe that his conduct was unlawful. GNYSB's Bylaws provide for the full
indemnification of GNYSB's directors, officers, and employees to the extent
permitted by law and permit, but do not require, GNYSB to purchase and maintain
insurance on behalf of any director, officer, employee, or agent of GNYSB.
 
     The NYBL requires that (i) stockholders be notified of any expenses or
other amounts paid to a director or officer by way of indemnification otherwise
than by court order or stockholder action, and (ii) the Superintendent be
notified of any amounts to be paid to a director or officer by way of
indemnification at least thirty (30) days prior to such payment.
 
REQUIRED VOTE FOR AUTHORIZATION OF CERTAIN ACTIONS
 
     AFC.  AFC's Certificate of Incorporation requires the approval of the
holders of at least 80% of the AFC's outstanding shares of voting stock to
approve certain "Business Combinations," as defined therein, and related
transactions. Under the DGCL, absent this provision, Business Combinations,
including mergers, consolidations and sales of all or substantially all of the
assets of a corporation must, subject to certain
 
                                       104
<PAGE>   112
 
exceptions, be approved by the vote of the holders of only a majority of the
outstanding shares of AFC Common Stock and any other affected class of stock.
Under AFC's Certificate of Incorporation, at least 80% approval of stockholders
is required in connection with any Business Combination involving an Interested
Stockholder (as defined below) except (i) in cases where the proposed
transaction has been approved in advance by a majority of those members of the
AFC Board who are unaffiliated with the Interested Stockholder and were
directors prior to the time when the Interested Stockholder became an Interested
Stockholder, or (ii) if the proposed transaction meets certain conditions set
forth therein which are designed to afford the stockholders a fair price in
consideration for their shares in which case, if a stockholder vote is required,
approval of only a majority of the outstanding shares of voting stock would be
sufficient. For purposes of this paragraph, the term "Interested Stockholder" is
defined to include any individual, corporation, partnership or other entity
(other than AFC or a subsidiary of AFC) which owns beneficially or controls,
directly or indirectly, 10% or more of the outstanding shares of voting stock of
AFC. This provision of AFC's Certificate of Incorporation applies to any
"Business Combination," which is defined to include (i) any merger or
consolidation of AFC or any of its subsidiaries with or into any Interested
Stockholder or Affiliate (as defined in the Certificate of Incorporation) of an
Interested Stockholder; (ii) any sale, lease, exchange, mortgage, pledge,
transfer, or other disposition to or with any Interested Stockholder or
Affiliate of an Interested Stockholder of 25% or more of the assets of AFC or
combined assets of AFC and AFC's subsidiaries; (iii) the issuance or transfer to
any Interested Stockholder or its Affiliate by AFC (or any subsidiary of AFC) of
any securities of AFC in exchange for any assets, cash or securities the value
of which equals or exceeds 25% of the fair market value of outstanding AFC
Common Stock; (iv) the adoption of any plan for the liquidation or dissolution
of AFC proposed by or on behalf of any Interested Stockholder or Affiliate
thereof; and (v) any reclassification of securities, recapitalization, merger or
consolidation of AFC which has the effect of increasing the proportionate share
of AFC Common Stock or any class of equity or convertible securities of AFC
owned directly or indirectly by an Interested Stockholder or Affiliate thereof.
 
     GNYSB.  The NYBL provides that a merger, voluntary liquidation, or sale of
assets by a savings bank must be approved by the vote of at least 66 2/3% of the
outstanding stock of such savings bank eligible to vote, unless the total assets
of the entity being acquired do not exceed 10% of the total assets of the
acquiring entity and the plan of merger does not change the name or the
authorized shares of capital stock of the acquiring entity or make or require
any other change or amendment for which the approval or consent of stockholders
of GNYSB would be required under the NYBL.
 
BUSINESS COMBINATIONS INVOLVING INTERESTED STOCKHOLDERS
 
     AFC.  Section 203 of the DGCL provides that a Person (as defined therein)
who owns 15% or more of the outstanding voting stock of a Delaware corporation
(an "Interested Stockholder") may not engage in any business combination with
such corporation for a period of three years following the time such person
became an Interested Stockholder, unless an exception to Section 203 of the DGCL
applies. Section 203(c)(3) broadly defines "business combination" to cover a
wide range of corporate transactions, including mergers, sales of assets,
issuances of stock, transactions with subsidiaries and receipts of
disproportionate financial benefits.
 
     Section 203 of the DGCL exempts the following transactions from its
requirements: (i) any business combination if, prior to the time such person
became an Interested Stockholder, the board of directors of the corporation
approved either the business combination or the transaction that resulted in the
stockholder becoming an Interested Stockholder; (ii) any business combination
involving a person who acquired at least 85% of the outstanding voting stock in
the transaction in which such person became an Interested Stockholder,
calculated without regard to those shares owned by the corporation's directors
who are also officers or certain employee stock plans; (iii) any business
combination with an Interested Stockholder that is approved by the board of
directors of the corporation and by a 66 2/3% vote of the outstanding voting
stock not owned by the Interested Stockholder; (iv) business combinations with
Interested Stockholders who become interested when the corporation is not
covered by the statute; and (v) certain business combinations that are proposed
after the corporation had received other acquisition proposals and that are
approved or not opposed by a majority of certain continuing members of the board
of directors of the corporation. A corporation may
 
                                       105
<PAGE>   113
 
exempt itself from the requirements of Section 203 of the DGCL by adopting an
amendment to its certificate of incorporation or bylaws electing not to be
governed by Section 203 of the DGCL. No such amendment has been adopted by AFC.
 
     Under the DGCL there is no statutory minimum beneficial ownership threshold
requirement for a stockholder rights plan to be authorized.
 
     GNYSB.  The NYBL does not have an analogous business combination statute to
Section 203 of the DGCL. For a stockholder rights plan to be authorized under
the NYBL the beneficial ownership threshold at which a stockholder's rights may
become void must be at least 20%. See "-- Rights Plans -- GNYSB."
 
APPRAISAL RIGHTS
 
     AFC.  Pursuant to Section 262 of the DGCL, a stockholder of AFC, including
those not entitled to vote, generally will be entitled to appraisal rights in
connection with a merger, consolidation, or similar transaction in which the
vote of the stockholders of AFC is required. No such appraisal rights, however,
are available for the shares of any class or series of stock if (i) such class
or series is either (a) listed on a stock exchange or quoted on the Nasdaq
National Market (as the AFC Common Stock is) or (b) held of record by more than
2,000 holders and (ii) such class or series receives stock in such transaction.
 
     GNYSB.  Pursuant to Section 6022 of the NYBL, a stockholder who is entitled
to vote on a merger, consolidation, or similar transaction who does not approve
such transaction generally is entitled to appraisal rights. See "THE
MERGER -- Dissenters' Rights."
 
OTHER CONSTITUENCIES
 
     AFC.  AFC's Certificate of Incorporation requires the AFC Board, when
evaluating offers to make a tender offer, merge or consolidate AFC, or purchase
or otherwise acquire all or substantially all of the assets and properties of
AFC, to determine what is in the best interests of AFC and AFC's stockholders.
In exercising such duty, AFC may, in connection with the exercise of its
judgment in determining what is in the best interest of AFC, Astoria Federal,
and the stockholders of AFC, give due consideration (to the extent permitted by
law) to all relevant factors, including, without limitation, those factors that
directors of AFC or any subsidiary of AFC may consider in evaluating any action
that may result in a change in control of the subsidiary, and the social and
economic effect of acceptance of such offer: (i) on AFC's and any of AFC's
subsidiary's present and future customers and employees, (ii) on the communities
in which AFC and any subsidiary of AFC operate or are located, (iii) on the
ability of AFC to fulfill its corporate objectives as a savings and loan holding
company, and (iv) on the ability of Astoria Federal to fulfill the objectives of
a federally chartered stock savings and loan association. The DGCL does not
address what factors a board of directors may consider in exercising such duty.
However, pursuant to case law interpreting the provisions of the DGCL, the board
of directors of a Delaware corporation, such as AFC, generally may consider the
impact of such a proposal on AFC's other constituencies, provided that doing so
bears some reasonable relationship to general stockholder interests.
 
     GNYSB.  GNYSB's Restated Organization Certificate contains a provision
requiring the GNYSB Board, when evaluating a change of control proposal
presented to GNYSB, to give due consideration to, among other things, the
possible effects on constituencies other than the stockholders of GNYSB. In
addition, Section 7015 of the NYBL as described above contains a provision
specifically permitting the GNYSB Board to consider, in taking any action,
including in the context of a change in control, both the long term and short
term interests of GNYSB and its stockholders and various constituencies.
 
RIGHTS PLANS
 
     AFC.  The AFC Rights Agreement, dated as of July 17, 1996, contains
provisions intended to protect stockholders in the event of unsolicited offers
or attempts to acquire AFC. The AFC Rights Agreement provides that attached to
each share of AFC Common Stock is an AFC Right, which constitutes a right to
purchase one one-hundredth of a share of AFC Junior Preferred Stock, at a price
of $100.00 per one one-
 
                                       106
<PAGE>   114
 
hundredth interest in a share of AFC Junior Preferred Stock, subject to
adjustment. The AFC Rights will expire on September 3, 2006, unless extended or
unless the AFC Rights are earlier redeemed by AFC, in each case as described
below.
 
     The AFC Rights will separate from the AFC Common Stock and become
exercisable for AFC Junior Preferred Stock within a specified time after (i) a
person or group (an "AFC Acquiring Person") other than AFC or its affiliates
acquires "beneficial ownership" of 10% or more of the outstanding AFC Common
Stock or (ii) the commencement of, or the public announcement of an intention to
commence, a tender or exchange offer which would result in the beneficial
ownership by a person or group (other than AFC or its affiliates) of 10% or more
of such outstanding AFC Common Stock (the "AFC Distribution Date"). The AFC
Rights Agreement provides that, until the AFC Distribution Date, the AFC Rights
will be transferred with and only with the transfer of AFC Common Stock and will
not be exercisable. In the event that any person or group becomes an AFC
Acquiring Person pursuant to the terms of the AFC Rights Agreement, each holder
of AFC Rights, other than the AFC Acquiring Person (whose rights will thereafter
be void), will thereafter have the right to receive upon exercise that number of
shares of AFC Common Stock having a market value of two times the purchase price
of an AFC Right.
 
     In the event that, at any time after a person becomes an AFC Acquiring
Person, AFC is acquired in a merger or other business combination transaction or
50% or more of its consolidated assets or earning power are sold, pursuant to
the terms of the AFC Rights, proper provision must be made so that each holder
of AFC Rights will thereafter have the right to receive, upon the exercise
thereof at the then current purchase price of an AFC Right, that number of
shares of common stock of the acquiring company which at the time of such
transaction will have a market value of two times the purchase price of an AFC
Right.
 
     At any time after a person or group becomes an AFC Acquiring Person and
prior to the acquisition by such person or group of 50% or more of the
outstanding AFC Common Stock, the AFC Board may exchange the AFC Rights (other
than the AFC Rights owned by such person or group which have become void), in
whole or in part, at an exchange ratio of one share of AFC Common Stock, or one
one-hundredth of a share of AFC Junior Preferred Stock (or equivalent class of
securities), per AFC Right (subject to adjustment).
 
     At any time prior to a person or group becoming an AFC Acquiring Person,
the AFC Board may redeem the AFC Rights in whole, but not in part, at a price of
$0.01 per AFC Right.
 
     The terms of the AFC Rights may be amended by the Board of Directors of AFC
without the consent of the holders of the AFC Rights. Until an AFC Right is
exercised, the holder thereof, as such, will have no rights as a stockholder of
AFC, including, without limitation, the right to vote or to receive dividends.
 
     The AFC Rights will not prevent a takeover of AFC. However, the AFC Rights
may cause substantial dilution to a person or group that acquires 10% or more of
the AFC Common Stock without receiving the prior approval of the AFC Board.
Accordingly, the AFC Rights may result in AFC being less attractive to a
potential acquiror and, in the event that the existence of the AFC Rights deter
certain potential acquirors, such AFC Rights could result in holders of AFC
Common Stock receiving less in the event of a takeover. The AFC Rights should
not interfere with any merger or other business combination approved by the AFC
Board.
 
     Each share of AFC Common Stock issued in the Merger will have attached
thereto an AFC Right.
 
     GNYSB.  On June 14, 1990, the GNYSB Board adopted the GNYSB Rights Plan and
declared a dividend distribution of one GNYSB Right for each outstanding share
of GNYSB Common Stock to holders of record at the close of business on June 25,
1990. The GNYSB Rights Agreement contains provisions intended to protect
stockholders in the event of unsolicited offers or attempts to acquire GNYSB and
is substantially similar in effect to the AFC Rights Agreement, except that the
relevant triggering threshold for certain events is beneficial ownership of 20%
or more of the outstanding GNYSB Common Stock.
 
     GNYSB and the rights agent with respect to the GNYSB Rights have executed
and delivered an amendment dated as of March 29, 1997 to the GNYSB Rights
Agreement. See "THE MERGER -- Amendment to the GNYSB Rights Agreement."

     This is an AGREEMENT AND PLAN OF MERGER, dated as of the 29th day of March,
1997 (this "Agreement"), by and among ASTORIA FINANCIAL CORPORATION, a Delaware
corporation (the "Parent"), ASTORIA FEDERAL SAVINGS AND LOAN ASSOCIATION, a
federally chartered savings and loan association and a wholly owned subsidiary
of the Parent (the "Association"), and THE GREATER NEW YORK SAVINGS BANK, a New
York chartered stock savings bank (the "Company"), as amended.
 
                             INTRODUCTORY STATEMENT
 
     The Board of Directors of each of the Parent and the Company (i) has
determined that this Agreement and the transactions contemplated hereby are in
the best interests of the Parent and the Company, respectively, and in the best
long-term interests of their respective stockholders, (ii) has determined that
this Agreement and the transactions contemplated hereby are consistent with, and
in furtherance of, its respective business strategies and (iii) has approved, at
meetings of each of such Boards of Directors, this Agreement.
 
     Concurrently with the execution and delivery of this Agreement, and as a
condition and inducement to the Parent's willingness to enter into this
Agreement, the Parent and the Company have entered into a Stock Option Agreement
(the "Option Agreement") pursuant to which the Company has granted to the Parent
an option to purchase shares of the Company's common stock, par value $1.00 per
share (the "Company Common Stock"), upon the terms and conditions therein
contained.
 
     The Parent and the Company desire to make certain representations,
warranties and agreements in connection with the business combination
transaction provided for herein and to prescribe various conditions to the
transaction.
 
     In consideration of their mutual promises and obligations hereunder, the
parties hereto adopt and make this Agreement and prescribe the terms and
conditions hereof and the manner and basis of carrying it into effect, which
shall be as follows:
 
                                   ARTICLE I
 
                                   THE MERGER
 
     SECTION 1.01  Structure of the Merger.  On the Effective Date (as defined
in Section 7.01), the Company will merge with and into the Association (the
"Merger"), with the Association being the surviving entity, pursuant to the
provisions of, and with the effect provided in, the rules and regulations of the
Office of Thrift Supervision (the "OTS") and the Banking Law of the State of New
York (the "NYBL") and pursuant to the terms and conditions of an agreement and
plan of merger to be entered into between the Association and the Company in a
form to be mutually agreed upon. The separate corporate existence of the Company
shall thereupon cease. The Association shall continue to be governed by the laws
of the United States and its name and separate corporate existence with all of
its rights, privileges, immunities, powers and franchises shall continue
unaffected by the Merger.
 
     SECTION 1.02  Effect on Outstanding Shares of Company Common Stock.  (a) By
virtue of the Merger, automatically and without any action on the part of the
holder thereof, each share of Company Common Stock issued and outstanding at the
Effective Time (as defined in Section 7.01) (other than (i) shares the holder of
which (the "Dissenting Stockholder") pursuant to any applicable law providing
for dissenters' or appraisal rights is entitled to receive payment in accordance
with the provisions of any such law, such holder to have only the rights
provided in any such law (the "Dissenters' Shares"), (ii) shares held directly
or indirectly by the Parent (other than shares held in a fiduciary capacity or
in satisfaction of a debt previously contracted), and (iii) shares held as
treasury stock of the Company (the "Excluded Shares") shall become and be
converted into, at the election of the holder thereof (subject to the provisions
of this Article), the right to receive: (x) the "Cash Consideration," described
below, or (y) the "Stock Consideration" consisting of shares of common stock,
par value $.01 per share of the Parent ("Parent Common Stock"), together with
the related preferred share purchase right issued pursuant to the rights
agreement (the "Parent
 
                                       A-1
<PAGE>   120
 
Rights Agreement") between the Parent and ChaseMellon Shareholder Services,
L.L.C. dated as of July 17, 1996 (the "Preferred Share Purchase Right"),
described below (collectively, the "Merger Consideration").
 
        (i) The Cash Consideration shall be $19.00 for each share of Company
Common Stock.
 
        (ii) The Stock Consideration shall be 0.50 of a share of Parent Common
Stock for each share of Company Common Stock.
 
        (iii) If between the date of this Agreement and the Effective Time the
outstanding shares of Parent Common Stock shall have been changed into a
different number of shares or into a different class, by reason of any stock
dividend, subdivision, reclassification, recapitalization, split, combination or
exchange of shares (each, a "Stock Adjustment"), the Merger Consideration shall
be adjusted correspondingly to the extent appropriate to reflect the Stock
Adjustment.
 
        (iv) As used herein, "Parent Market Value" shall be the average of the
mean between the closing high bid and low asked prices of a share of Parent
Common Stock, as reported on the National Association of Securities Dealers
Automated Quotation System National Market System (the "Nasdaq"), for the 30
consecutive trading days immediately preceding the day (the "Valuation Date")
which is the day that is the latest of (i) the day of expiration of the last
waiting period with respect to any of the required regulatory approvals, as
defined in Section 5.01(b), (ii) the day on which the last of the required
regulatory approvals, as defined in Section 5.01(b), is obtained and (iii) the
day on which the last of the required stockholder approvals have been received.
 
     (b) As of the Effective Time, each Excluded Share, other than Dissenters'
Shares, shall be cancelled and retired and cease to exist, and no exchange or
payment shall be made with respect thereto.
 
     (c) As of the Effective Time, all shares of Company Common Stock other than
Excluded Shares shall no longer be outstanding and shall be automatically
cancelled and retired and shall cease to exist, and each holder of a certificate
formerly representing any such shares of Company Common Stock shall cease to
have any rights with respect thereto, except the right to receive the Merger
Consideration. After the Effective Time, there shall be no transfers on the
stock transfer books of the Parent.
 
     SECTION 1.03  Effect on Outstanding Shares of Company Preferred Stock.  (a)
Subject to Section 4.18 hereof, at or prior to the Effective Time, the Company
shall use such procedures as they deem necessary and appropriate in order to
cause the shares of Series A ESOP Convertible Preferred Stock to be converted
into Company Common Stock which shall include, if necessary, giving notice of
its intention to redeem the Series A ESOP Convertible Preferred Stock in
accordance with the terms thereof.
 
     (b) At or immediately prior to the Effective Time, the Certificate of
Incorporation of the Parent shall be amended to (i) change the par value of the
authorized shares of Parent Preferred Stock from $0.01 per share to $1.00 per
share and (ii) fix the preferences of a newly-created Series B Preferred Stock
of the Parent (the "Parent Series B Preferred Stock") to have terms
substantially identical, and in any event no less favorable, to those of the 12%
Noncumulative Preferred Stock, Series B of the Company (the "Company Series B
Preferred Stock") and agreeable to the Company; provided, that, the Parent may,
in its sole discretion, effect such an amendment provided for in clause (ii)
above through a Certificate of Designations filed pursuant to Section 151 of the
Delaware General Corporation Law. At the Effective Time, each share of Company
Series B Preferred Stock issued and outstanding immediately prior to the
Effective Time shall, by virtue of the Merger and without any action on the part
of the holder thereof, be converted into, and shall become, one share of the
Parent Series A Preferred Stock.
 
     SECTION 1.04  Fractional Shares.  Notwithstanding any other provision
hereof, no fraction of a whole share of Parent Common Stock and no certificates
or scrip therefor will be issued in the Merger; instead, the Parent shall pay to
each holder of Company Common Stock who would otherwise be entitled to a
fractional share an amount in cash, rounded to the nearest cent, determined by
multiplying such fraction by the Parent Market Value.
 
     SECTION 1.05  Elections.  (a) Subject to the allocation procedures set
forth in this Article, each holder of Company Common Stock will be entitled,
with respect to the Merger Consideration to be received for each
 
                                       A-2
<PAGE>   121
 
share of Company Common Stock held by such holder, to (i) elect to receive the
Stock Consideration (a "Stock Election") with respect to such holder's Company
Common Stock ("Stock Election Shares"), (ii) elect to receive the Cash
Consideration (a "Cash Election") with respect to such holder's Company Common
Stock ("Cash Election Shares"), (iii) make no election (a "No-Election") with
respect to such holder's Company Common Stock ("No-Election Shares") or (iv)
elect to make a Stock Election with respect to some of such holder's shares of
Company Common Stock and a Cash Election with respect to the remaining shares of
Company Common Stock held by such holder (a "Split Election"). Any Dissenting
Shares shall be deemed to be No-Election Shares. Notwithstanding the foregoing,
in order to make a Stock Election, the number of shares of Company Common Stock
a Company stockholder elects to convert must equal or exceed 100 shares.
 
     (b) An election form and other appropriate transmittal materials (the
"Letter of Transmittal and Election Form") will be mailed within three business
days after the Effective Date to each holder of record of Company Common Stock
as of the Effective Time permitting such holder (or in the case of nominee
record holders, the beneficial owner through proper instructions and
documentation) to make a (i) Stock Election, (ii) Cash Election, (iii)
No-Election or (iv) Split Election. Holders who hold in a variety of capacities
may make a separate election in each capacity. Any election shall have been
properly made only if a bank or trust company designated by the Parent (the
"Exchange Agent") shall have actually received a properly completed Letter of
Transmittal and Election Form by the Election Deadline, described below. A
Letter of Transmittal and Election Form will be properly completed only if
accompanied by certificates representing all shares of Company Common Stock
converted thereby. Any shares of Company Common Stock with respect to which the
holder thereof shall not, as of the Election Deadline, have made such an
election by submission to the Exchange Agent of an effective, properly completed
Letter of Transmittal and Election Form shall be deemed to be No-Election Shares
(as defined herein). The Exchange Agent shall have reasonable discretion to
determine when any election, modification or revocation is received and whether
any such election, modification or revocation has been properly made.
 
     (c) The Election Deadline shall be 5:00 p.m., Eastern Time, on the 10th
business day following but not including the date of mailing of the Letter of
Transmittal and Election Form or such other date as the Parent and the Company
shall mutually agree upon.
 
     SECTION 1.06  Allocations of Merger Consideration.  (a) As provided below,
75% of the shares of Company Common Stock will be converted into the right to
receive the Stock Consideration. The Exchange Agent shall effectuate the
allocations of the Merger Consideration described below among the holders of
Company Common Stock within five business days after the Election Deadline.
 
     (b) If the aggregate number of Cash Election Shares exceeds the number of
shares of Company Common Stock equal to 25% of the shares of Company Common
Stock outstanding at the Effective Time (excluding such shares which are to be
cancelled and retired in accordance with Section 1.02(b)) (the "Cash Election
Number"), all Stock Election Shares and all No-Election Shares outstanding at
the Effective Time shall be converted into the right to receive the Stock
Consideration, and the Cash Election Shares shall be converted into the right to
receive the Stock Consideration and the Cash Consideration in the following
manner:
 
     each Cash Election Share shall be converted into the right to receive (i)
     an amount in cash, without interest, equal to the product, rounded to the
     nearest 1c, of (x) the Cash Consideration and (y) a fraction (the "Cash
     Fraction"), the numerator of which shall be the Cash Election Number and
     the denominator of which shall be the total number of Cash Election Shares,
     and (ii) a number of shares of Parent Common Stock equal to the product,
     rounded to four decimal places, of (x) the Stock Consideration and (y) a
     number equal to one minus the Cash Fraction.
 
     (c) If the aggregate number of Stock Election Shares exceeds the number of
shares of Company Common Stock equal to 75% of the shares of Company Common
Stock outstanding at the Effective Time (excluding such shares which are to be
cancelled and retired in accordance with Section 1.02(d)) (the "Stock Election
Number"), all Cash Election Shares and all No-Election Shares shall be converted
into the right to
 
                                       A-3
<PAGE>   122
 
receive the Cash Consideration, and all Stock Election Shares shall be converted
into the right to receive the Stock Consideration and the Cash Consideration in
the following manner:
 
     each Stock Election Share shall be converted into the right to receive (i)
     a number of shares of Parent Common Stock equal to the product, rounded to
     four decimal places, of (x) the Stock Consideration and (y) a fraction (the
     "Stock Fraction"), the numerator of which shall be the Stock Election
     Number and the denominator of which shall be the total number of Stock
     Election Shares, and (ii) an amount of cash, without interest, equal to the
     product, rounded to the nearest 1c, of (x) the Cash Consideration and (y) a
     number equal to one minus the Stock Fraction.
 
     (d) In the event that the number of Cash Election Shares does not exceed
the Cash Election Number and the number of Stock Election Shares does not exceed
the Stock Election Number, all Cash Election Shares shall be converted into the
right to receive the Cash Consideration, all Stock Election Shares shall be
converted into the right to receive the Stock Consideration, and the No-Election
Shares shall be converted into either the right to receive the Stock
Consideration or the Cash Consideration as determined by random selection so
that the result provided for in Section 1.06(a) is achieved.
 
     (e) The random selection process to be used by the Exchange Agent pursuant
to this Section 1.06 will consist of drawing by lot or such other process as the
Exchange Agent deems equitable and necessary to effect the allocations described
in such subparagraphs.
 
     SECTION 1.07  Exchange Procedures.  (a) At and after the Effective Time,
each certificate previously representing shares of Company Common Stock (except
as specifically set forth in Section 1.02) shall represent only the right to
receive the Merger Consideration and each certificate previously representing
shares of Company Series B Preferred Stock shall be deemed to represent shares
of Parent Series B Preferred Stock (the Company Common Stock Certificates and
the Company Preferred Stock Certificates, together, are herein referred to as
the "Company Certificates").
 
     (b) As of the Effective Time, the Parent shall deposit, or shall cause to
be deposited, with the Exchange Agent, for the benefit of the holders of shares
of Company Common Stock, for exchange in accordance with this Section 1.07, an
estimated amount of cash sufficient to pay the aggregate Cash Consideration to
be paid pursuant to Section 1.02 and the aggregate amount of cash paid in lieu
of fractional shares to be paid pursuant to Section 1.04, and the Parent shall
reserve for issuance with its Transfer Agent and Registrar, the aggregate Stock
Consideration and Parent Series B Preferred Stock to be issued.
 
     (c) The Letter of Transmittal and Election Form to be mailed within three
business days of the Effective Date shall specify that delivery shall be
effected, and risk of loss and title to the Company Common Stock Certificates
shall pass, only upon delivery of the Company Common Stock Certificates to the
Exchange Agent, shall be in a form and contain any other provisions as the
Parent may reasonably determine and shall include instructions for use in
effecting the surrender of the Company Certificates in exchange for the Merger
Consideration or Parent Series B Preferred Stock, as appropriate. Upon the
proper surrender of a Company Certificate or Company Certificates to the
Exchange Agent, together with a properly completed and duly executed Letter of
Transmittal and Election Form, the holder of such Company Certificate or Company
Certificates shall be entitled to receive in exchange therefor (i) a certificate
representing that number of whole shares of Parent Common Stock or Preferred
Series B Stock, if any, that such holder has the right to receive pursuant to
Article I of this Agreement and (ii) a check in the amount equal to the cash, if
any, which such holder has the right to receive pursuant to Article I of this
Agreement (including any cash in lieu of any fractional shares of Parent Common
Stock to which such holder is entitled to pursuant to Section 1.04 and any
dividend or other distributions to which such holder of Parent Common Stock is
entitled to pursuant to Section 1.07(d)). Holders of Company Preferred Stock
Certificates shall not be required to exchange such certificates for
certificates representing Parent Series B Preferred Stock but may do so in
accordance with the provisions hereof. Upon the proper surrender of a Company
Certificate or Company Certificates previously representing shares of Company
Preferred Stock, the holder of such Company Certificates or Company Certificates
shall be entitled to receive in exchange therefor a certificate representing the
same number of shares of Parent Series B Preferred Stock. The Company
Certificate or Company Certificates so surrendered shall forthwith be cancelled.
As soon as practicable after completion of the allocations of the Merger
 
                                       A-4

Consideration and in no event later than ten business days after the Election
Deadline, the Exchange Agent shall distribute Parent Common Stock and cash as
provided herein. The Exchange Agent shall not be entitled to vote or exercise
any rights of ownership with respect to the shares of Parent Common Stock held
by it from time to time hereunder, except that it shall receive and hold all
dividends or other distributions paid or distributed with respect to such shares
for the account of the persons entitled thereto. In the event of a transfer of
ownership of any shares of Company Common Stock not registered in the transfer
records of the Company, the Cash Consideration shall be paid and the Stock
Consideration shall be issued to the transferee if the Company Certificate
representing such Company Common Stock is presented to the Exchange Agent,
accompanied by documents sufficient, in the reasonable judgment of the Parent
and the Exchange Agent, (x) to evidence and effect such transfer and (y) to
evidence that all applicable stock transfer taxes have been paid.
 
     (d) No interest will be paid or accrued on the Cash Consideration. No
dividend or other distributions declared or made after the Effective Time with
respect to the Parent Common Stock shall be remitted to any person entitled to
receive shares of Parent Common Stock until such person surrenders the Company
Common Stock Certificate or Company Common Stock Certificates, at which time
such dividends shall be remitted to such persons, without interest.
 
     (e) From and after the Effective Time, there shall be no transfers on the
stock transfer records of the Company of any shares of Company Common Stock or
Company Preferred Stock that were outstanding immediately prior to the Effective
Time. If after the Effective Time Company Certificates are presented to the
Parent or the Association, they shall be cancelled and exchanged for the Merger
Consideration or Parent Series B Preferred Stock, as appropriate, deliverable in
respect thereof pursuant to this Agreement in accordance with the procedures set
forth in this Section 1.07.
 
     (f) Any portion of the aggregate Cash Consideration or the proceeds of any
investments thereof that remains unclaimed by the stockholders of the Company
for six (6) months after the Effective Time shall be repaid by the Exchange
Agent to the Parent upon the written request of the Parent. After such request
is made, any stockholders of the Company who have not theretofore complied with
this Section 1.07 shall look only to the Parent for payment and issuance of
their Merger Consideration deliverable in respect of each share of Company
Common Stock such stockholder holds as determined pursuant to this Agreement
without any interest thereon. If outstanding certificates for shares of Company
Common Stock are not surrendered or the payment for them is not claimed prior to
the date on which such payments would otherwise escheat to or become the
property of any governmental unit or agency, the unclaimed items shall, to the
extent permitted by abandoned property and any other applicable law, become the
property of the Parent (and to the extent not in its possession shall be paid
over to it), free and clear of all claims or interest of any person previously
entitled to such claims. Notwithstanding the foregoing, none of the Parent, the
Association, the Exchange Agent or any other person shall be liable to any
former holder of Company Common Stock for any amount delivered to a public
official pursuant to applicable abandoned property, escheat or similar laws.
 
     (g) The Parent and the Exchange Agent shall be entitled to rely upon the
Company's stock transfer books to establish the identity of those persons
entitled to receive the Merger Consideration or shares of Parent Series B
Preferred Stock, which books shall be conclusive with respect thereto. In the
event of a dispute with respect to ownership of stock represented by any Company
Certificate, the Parent and the Exchange Agent shall be entitled to deposit any
consideration represented thereby in escrow with an independent third party and
thereafter be relieved with respect to any claims thereto.
 
     (h) In the event any Company Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
such Company Certificate to be lost, stolen or destroyed and, if required by the
Exchange Agent, the posting by such person of a bond in such amount as the
Exchange Agent may direct as indemnity against any claim that may be made
against it with respect to such Company Certificate, the Exchange Agent will
issue in exchange for such lost, stolen or destroyed Company Certificate the
Merger Consideration or the shares of Parent Series B Preferred Stock
deliverable in respect thereof pursuant to this Agreement.

     SECTION 1.08  Dissenters' Rights.  (a) Any Dissenting Stockholder who shall
be entitled to dissenters' rights with respect to his or her Dissenters' Shares,
as provided in Sections 604 and 6022 of the NYBL, shall not be entitled to the
Merger Consideration, unless and until the holder thereof shall have failed to
perfect or shall have effectively withdrawn or lost such holder's right to
dissent from the Merger under such law, and shall be entitled to receive only
the payment to the extent provided for therein with respect to such Dissenters'
Shares. If any Dissenting Stockholder shall fail to perfect or shall have
effectively withdrawn or lost the right to dissent, the Dissenters' Shares held
by such Dissenting Stockholder shall thereupon be treated as No-Election Shares.
 
     (b) The Company shall (i) give the Parent prompt written notice of the
receipt of any notice from a stockholder to exercise any dissenters' rights,
(ii) not settle nor offer to settle any demand for payment without the prior
written consent of the Parent and (iii) not waive any failure strictly to comply
with any procedural requirements of Section 6022 of the NYBL.
 
     SECTION 1.09  Options.  (a) Subject to Section 1.09(b) and (c), at the
Effective Time, each option to purchase a share of Company Common Stock that has
been granted pursuant to Company's Long-Term Incentive Program, 1996 Equity
Incentive Plan and 1996 Non-Employee Directors' Stock Option Plan (collectively,
the "Company's Option Plans") and that is outstanding and unexercised at the
Effective Time (whether or not such option is otherwise vested or exercisable)
(each, an "Outstanding Company Option") shall be cancelled and shall cease to be
exercisable. In consideration for such cancellation, the Parent shall, with
respect to each Outstanding Company Option, pay to the holder thereof an amount
equal to the excess (if any) of (a) the Cash Consideration over (b) price at
which the holder may acquire a share of Company Common Stock upon exercise of
such Outstanding Company Option (the "Option Cashout Payment"). The Parent shall
make such payment as soon as practicable following the Effective Time or, if
later in the case of any holder of an Outstanding Company Option, the date on
which such holder delivers to the Parent his written acceptance of an Option
Cashout Payment as full and complete consideration for the cancellation of each
Outstanding Company Option held by him. The Company shall take such action as is
necessary or appropriate under the terms of Company's Option Plans to convert
each Outstanding Company Option, as of the Effective Time, into the right to
receive an Option Cashout Payment upon the terms and conditions set forth
herein. Payment hereunder shall be subject to withholding for applicable
federal, state and local taxes.
 
     (b) Mr. Gerard C. Keegan and any two other officers of the Company to be
designated by Mr. Keegan or any one or more of them may, by written notice to
the Parent received by the Parent not less than the day that is ten (10)
business days prior to the Effective Time, elect to convert all or any portion
of the Outstanding Company Options held by them into options ("Parent Options")
to purchase shares of Parent Common Stock. Any such election shall identify the
Outstanding Company Options to be converted into Parent Options and shall become
irrevocable upon receipt by the Parent of the notice of election. Any conversion
pursuant to this Section 1.09(b) shall be effected by issuing to the electing
individual Parent Options to purchase the number of shares of Parent Common
Stock (rounded down to the nearest whole share) equal to the product of (i) the
number of shares of Company Common Stock subject to the Outstanding Company
Options being converted, and (ii) the Stock Consideration. The exercise price
per share for each share of Parent Common Stock subject to a Parent Option
issued under this Section 1.09(b) shall be equal to the quotient of the per
share exercise price of the Outstanding Company Option being converted into such
Parent Options divided by the Stock Consideration, rounded up to the next whole
cent. Each such Parent Option (i) shall be fully vested and non-forfeitable,
(ii) shall be exercisable at the same time and for the same terms as the related
Outstanding Company Options, (iii) shall not be subject to any condition, except
as may be required under applicable securities laws, including without
limitation the continued employment by the Parent of the holder thereof, and
(iv) shall be evidenced by a Parent Option agreement in a form to be provided by
the Parent that is reasonably acceptable to the Company, and that shall provide
for reasonable registration rights. No payment shall be made pursuant to Section
1.09(a) with respect to any portion of a Outstanding Company Option that is
converted into a Parent Option as aforesaid. At or prior to the Effective Time,
Parent shall (i) take all corporate action necessary to reserve for issuance a
sufficient number of shares of Parent Common Stock for delivery upon exercise of
Outstanding Company Options converted into Parent Options in accordance with
this Section and (ii) file a registration statement on Form S-8 (or any
successor or other appropriate form)
 
                                       A-6
<PAGE>   125
 
with respect to the Parent Common Stock subject to such Parent Options. Parent
shall use its best efforts to maintain the effectiveness of such registration
statement (and maintain the current status of the prospectus or prospectuses
contained therein) for so long as such Parent Options remain outstanding.
 
     (c) Any holder of an Outstanding Company Option not included in Section
1.09(b) may request a conversion identical to that described in Section 1.09(b);
provided, however, that the Parent may, in its sole and absolute discretion,
determine whether to accept or deny such request. If the Parent denies such
request, the holder of the Outstanding Company Option shall be subject to
Section 1.09(a).
 
     SECTION 1.10  Directors and Officers of the Association after Effective
Time.  At the Effective Time, the directors of the Association shall consist of
(a) the Directors of the Association serving immediately prior to the Effective
Time and (b) such additional persons who shall become directors of the Parent in
accordance with Section 4.15.
 
     SECTION 1.11  Liquidation Account.  The Association shall expressly assume
the Company's liquidation account and its obligations related thereto in the
Merger. In the event of a complete liquidation of the Association, and only in
such event, any amounts distributable from such liquidation account will be
determined in accordance with the rules and regulations pertaining to
conversions by a thrift from mutual to stock form of organization set forth in
Section 86.4(f) of the General Regulations of the Banking Board of the State of
New York. No merger, consolidation, purchase of bulk assets with assumption of
savings accounts and other liabilities, or similar transaction, whether or not
the Association is the surviving institution, will be deemed to be a complete
liquidation for this purpose, and, in any such transaction, the liquidation
account shall be assumed by the surviving institution.

                         REPRESENTATIONS AND WARRANTIES
 
     SECTION 2.01  Disclosure Letters.  On or prior to the execution hereof, the
Company and the Parent have delivered to each other a letter (its "Disclosure
Letter") setting forth, among other items, the disclosure of which is required
or appropriate in relation to any or all of its representations and warranties
(and making specific reference to the Section of this Agreement to which they
relate), other than Section 2.03(h); provided, that (a) no such fact,
circumstance or event is required to be set forth in the Disclosure Letter as an
exception to a representation or warranty if its absence is not reasonably
likely to result in the related representation or warranty being deemed untrue
or incorrect under the standards established by Section 2.02, and (b) the mere
inclusion of an item in the Disclosure Letter shall not be deemed an admission
by a party that such item represents a material exception or that such item is
reasonably likely to result in a Material Adverse Effect (as defined in Section
2.02(b)).
 
     SECTION 2.02  Standards.  (a) No representation or warranty of the Company
or the Parent contained in Section 2.03 or 2.04, respectively, shall be deemed
untrue or incorrect, and no party hereto shall be deemed to have breached a
representation or warranty, on account of the existence of any fact,

accepted accounting principles consistently applied during the periods involved,
except as may be noted therein.

plans, contracts, agreements, arrangements, including, but not limited to,
"employee benefit plans," as defined in Section 3(3) of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA"), incentive and welfare
policies, contracts, plans and arrangements and all trust agreements related
thereto with respect to any present or former directors, officers, or other
employees of the Company or any of its Subsidiaries (hereinafter referred to
collectively as the "Employee Plans"). All of the Employee Plans comply in all
material respects with all applicable requirements of ERISA, the Code and other
applicable laws; there has occurred no "prohibited transaction" (as defined in
Section 406 of ERISA or Section 4975 of the Code) which is likely to result in
the imposition of any penalties or taxes under Section 502(i) of ERISA or
Section 4975 of the Code upon the Company or any of its Subsidiaries. No
liability, to the Pension Benefit Guaranty Corporation, has been or is expected
by the Company or any of its Subsidiaries to be incurred with respect to any
Employee Plan which is subject to Title IV of ERISA ("Pension Plan"), or with
respect to any "single-employer plan" (as defined in Section 4001(a) of ERISA)
currently or formerly maintained by the Company or any entity which is
considered one employer with the Company under Section 4001(b)(1) of ERISA or
Section 414 of the Code (an "ERISA Affiliate"). No Pension Plan had an
"accumulated funding deficiency" (as defined in Section 302 of ERISA (whether or
not waived)) as of the last day of the end of the most recent plan year ending
prior to the date hereof; the fair market value of the assets of each Pension
Plan exceeds the present value of the "benefit liabilities" (as defined in
Section 4001(a)(16) of ERISA) under such Pension Plan as of the end of the most
recent plan year with respect to the respective Pension Plan ending prior to the
date hereof, calculated on the basis of the actuarial assumptions used in the
most recent actuarial valuation for such Pension Plan as of the date hereof; and
no notice of a "reportable event" (as defined in Section 4043 of ERISA) for
which the 30-day reporting requirement has not been waived has been required to
be filed for any Pension Plan within the 12-month period ending on the date
hereof. Neither the Company nor any Subsidiary of the Company has provided, or
is required to provide, security to any Pension Plan or to any single-employer
 
                                      A-12
<PAGE>   131
 
plan of an ERISA Affiliate pursuant to Section 401(a)(29) of the Code. Neither
the Company, its Subsidiaries, nor any ERISA Affiliate has contributed to any
"multiemployer plan", as defined in Section 3(37) of ERISA, on or after
September 26, 1980. Each Employee Plan of the Company or of any of its
Subsidiaries which is an "employee pension benefit plan" (as defined in Section
3(2) of ERISA) and which is intended to be qualified under Section 401(a) of the
Code (a "Qualified Plan") has received a favorable determination letter from the
Internal Revenue Service (the "IRS") and the Company and its Subsidiaries are
not aware of any circumstances likely to result in revocation of any such
favorable determination letter. Each Qualified Plan which is an "employee stock
ownership plan" (as defined in Section 4975(e)(7) of the Code) has satisfied all
of the applicable requirements of Sections 409 and 4975(e)(7) of the Code and
the regulations thereunder in all material respects and any assets of any such
Qualified Plan that are not allocated to participants' individual accounts are
pledged as security for, and may be applied to satisfy, any securities
acquisition indebtedness. There is no pending or, to the knowledge of the
Company, threatened litigation, administrative action or proceeding relating to
any Employee Plan. There has been no announcement or commitment by the Company
or any Subsidiary of the Company to create an additional Employee Plan, or to
amend an Employee Plan except for amendments required by applicable law which do
not materially increase the cost of such Employee Plan; and except as
specifically identified on the Disclosure Letter, the Company and its
Subsidiaries do not have any obligations for post-retirement or post-employment
benefits under any Employee Plan that cannot be amended or terminated upon no
more than sixty (60) days' notice without incurring any liability thereunder,
except for coverage required by Part 6 of Title I of ERISA or Section 4980B of
the Code. With respect to the Company or any of its Subsidiaries, except as
specifically identified on the Disclosure Letter, the execution and delivery of
this Agreement and the consummation of the transactions contemplated hereby will
not result in any payment or series of payments by the Company or any Subsidiary
of the Company to any person which is an "excess parachute payment" (as defined
in Section 280G of the Code), increase or secure (by way of a trust or other
vehicle) any benefits payable under any Employee Plan other than a Pension Plan,
or except to the extent contemplated by Sections 1.09 and 4.03 accelerate the
time of payment or vesting of any such benefit. With respect to each Employee
Plan, the Company has supplied to the Parent a true and correct copy of (A) the
annual report on the applicable form of the Form 5500 series filed with the IRS
for the most recent three plan years, (B) such Employee Plan, including
amendments thereto, (C) each trust agreement, insurance contract or other
funding arrangement relating to such Employee Plan, including amendments
thereto, (D) the most recent summary plan description and summary of material
modifications thereto for such Employee Plan, including amendments thereto, if
the Employee Plan is subject to Title I of ERISA, (E) the most recent actuarial
report or valuation if such Employee Plan is a Pension Plan and any subsequent
changes to the actuarial assumptions contained therein and (F) the most recent
determination letter issued by the IRS if such Employee Plan is a Qualified
Plan.
 
     (o) Termination Benefits.  The Disclosure Letter contains a complete and
accurate schedule showing the present value as of September 30, 1997 of the
monetary amounts payable and identifying the in-kind benefits due under the
Specified Compensation and Benefit Programs (as defined herein) for each Named
Individual (as defined herein) individually and for all persons other than the
Named Individuals as a group. For purposes hereof, "Specified Compensation and
Benefit Programs" shall include all employment agreements, change in control
agreements, severance or special termination agreements, severance plans,
pension, retirement or deferred compensation plans for non-employee directors,
supplemental executive retirement programs, tax indemnification agreements,
outplacement programs, cash bonus programs, stock appreciation right, phantom
stock or stock unit plan, and health, life, disability and other insurance or
welfare plans, but shall not include any tax-qualified pension, profit-sharing
or employee stock ownership plan or any Outstanding Company Options. For
purposes hereof, "Named Individual" shall include each non-employee director of
the Company or any of its subsidiaries and each executive officer of the
Company. For purposes of preparing the Disclosure Letter, the present value of
the benefits payable under the Specified Compensation and Benefit Programs shall
be determined as follows: (i) it shall be assumed that a change of control of
the Company occurs on September 30, 1997 and that each person entitled to
benefits under the Specified Compensation and Benefit Programs is discharged as
of September 30, 1997; (ii) it shall be assumed that all compensation levels
remain constant; (iii) it shall be assumed that the present value of any payment
or benefit which would be due and payable before November'1, 1997 is equal to

action before any court or governmental agency is pending against the Parent,
the Association or any of its Subsidiaries, and, to the best of the Parent's
knowledge, no such litigation, proceeding, controversy, claim or action has been

supervisory letter from any Government Regulator, nor has it been advised by any

     (m) Labor Matters.  Neither the Parent, the Association nor any of its
Subsidiaries is or has ever been a party to, or is or has ever been bound by,
any collective bargaining agreement, contract, or other agreement or
understanding with a labor union or labor organization with respect to its
employees, nor is the Parent, the Association or any of its Subsidiaries the

     (n) Employee Benefit Plans.  The Disclosure Letter contains a complete and
accurate list of all pension, retirement, stock option, stock purchase, stock
ownership, savings, stock appreciation right, profit sharing, deferred
compensation, consulting, bonus, group insurance, severance and other benefit
plans, contracts, agreements, arrangements, including, but not limited to,
"employee benefit plans," as defined in Section 3(3) of ERISA, incentive and
welfare policies, contracts, plans and arrangements and all trust agreements
related thereto with respect to any present or former directors, officers, or
other employees of the Parent or any of its
 
                                      A-21
<PAGE>   140
 
Subsidiaries (hereinafter referred to collectively as the "Parent Employee
Plans"). All of the Parent Employee Plans comply in all material respects with
all applicable requirements of ERISA, the Code and other applicable laws; there
has occurred no "prohibited transaction" (as defined in Section 406 of ERISA or
Section 4975 of the Code) which is likely to result in the imposition of any
penalties or taxes under Section 502(i) of ERISA or Section 4975 of the Code
upon the Parent or any of its subsidiaries. No liability, to the Pension Benefit
Guaranty Corporation, has been or is expected by the Parent or any of its
Subsidiaries to be incurred with respect to any Parent Employee Plan which is
subject to Title IV of ERISA ("Parent Pension Plan"), or with respect to any
"single-employer plan" (as defined in Section 4001(a) of ERISA) currently or
formerly maintained by the Parent or any entity which is considered one employer
with the Parent under Section 4001(b)(1) of ERISA or Section 414 of the Code (an
"ERISA Affiliate"). No Parent Pension Plan had an "accumulated funding
deficiency" (as defined in Section 302 of ERISA (whether or not waived)) as of
the last day of the end of the most recent plan year ending prior to the date
hereof; the fair market value of the assets of each Parent Pension Plan exceeds
the present value of the "benefit liabilities" (as defined in Section
4001(a)(16) of ERISA) under such Parent Pension Plan as of the end of the most
recent plan year with respect to the respective Parent Pension Plan ending prior
to the date hereof, calculated on the basis of the actuarial assumptions used in
the most recent actuarial valuation for such Parent Pension Plan as of the date
hereof; and no notice of a "reportable event" (as defined in Section 4043 of
ERISA) for which the 30-day reporting requirement has not been waived has been
required to be filed for any Parent Pension Plan within the 12-month period
ending on the date hereof. Neither the Parent nor any Subsidiary of the Parent
has provided, or is required to provide, security to any Parent Pension Plan or
to any single-employer plan of an ERISA Affiliate pursuant to Section 401(a)(29)
of the Code. Neither the Parent, its Subsidiaries, nor any ERISA Affiliate has
contributed to any "multiemployer plan", as defined in Section 3(37) of ERISA,
on or after September 26, 1980. Each Parent Employee Plan of the Parent or of
any of its Subsidiaries which is an "employee pension benefit plan" (as defined
in Section 3(2) of ERISA) and which is intended to be qualified under Section
401(a) of the Code (a "Parent Qualified Plan") has received a favorable
determination letter from the IRS and the Parent and its Subsidiaries are not
aware of any circumstances likely to result in revocation of any such favorable
determination letter. There is no pending or, to the knowledge of the Parent,
threatened litigation, administrative action or proceeding relating to any
Parent Employee Plan.
 
     (o) Compliance with Laws.  The Parent, the Association and each of its
Subsidiaries has all permits, licenses, certificates of authority, orders and
approvals of, and has made all filings, applications and registrations with,
federal, state, local and foreign governmental or regulatory bodies that are
required in order to permit it to carry on its business as it is presently
conducted; all such permits, licenses, certificates of authority, orders and
approvals are in full force and effect, and, to the best knowledge of the
Parent, no suspension or cancellation of any of them is threatened. Since the
date of its incorporation, the corporate affairs of the Parent have not been
conducted in violation of any law, ordinance, regulation, order, writ, rule,
decree or approval of any Governmental Entity. The business of the Parent and
its Subsidiaries are not being conducted in violation of any law, ordinance,
regulation, order, writ, rule or decree approval of any Governmental Entity.
 
     (p) Fees.  Other than the financial advisory services performed for the
Parent by Merrill Lynch & Co., pursuant to an agreement, a true and complete
copy of which has been previously delivered to the Company, neither the Parent,
the Association nor any of its Subsidiaries, nor any of their respective
officers, directors, employees or agents, has employed any broker or finder or
incurred any liability for any financial advisory fees, brokage fees,
commissions, or finder's fee, and no broker or finder has acted directly or
indirectly for the purchase of any Subsidiary of the Parent, in connection with
the Agreement or the transactions contemplated hereby.

Subsidiaries:
 
           (A) Each of the Parent and its Subsidiaries, the Participation

without limitation, any proposal or offer to stockholders of the Company) with
respect to a merger, consolidation or similar transaction involving, or any
purchase of all or more than 10% of the assets or any equity securities of, the
Company or any of its material Subsidiaries (any such proposal or offer being
hereinafter referred to as an "Acquisition Proposal") or, (b) except to the
extent legally required for the discharge by the board of directors of its
fiduciary duties as advised in writing by such board's counsel, engage in any
negotiations concerning, or provide any confidential information or data to, or
have any discussions with, any person relating to an Acquisition Proposal, or
otherwise facilitate any effort or attempt to make or implement an Acquisition
Proposal. The Company will notify the Parent immediately if any such inquiries,
proposals or offers are received by, any such information is requested from, or
any such negotiations or discussions are sought to be initiated or continued
with the Company after the date hereof, and the identity of
 
                                      A-29
<PAGE>   148
 
the person making such inquiry, proposal or offer and the substance thereof.

Subsidiaries.

Parent, the Company shall modify and change its loan, litigation, real estate
valuation policies and practices (including loan classifications and levels of
reserves) and investment and asset/liability management policies and practices
after the date on which all required regulatory approval and shareholder
approvals are received and after receipt of written confirmation from the Parent
that it is not aware of any fact or circumstance that would prevent completion
of the Merger and prior to the Effective Time so as to be consistent on a
mutually satisfactory basis with those of the Association; provided, that such
policies and procedures are not prohibited by generally accepted accounting
principles or all applicable laws and regulations.
 
     (b) The Company's representations, warranties and covenants contained in
this Agreement shall not be deemed to be untrue or breached in any respect for
any purpose as a consequence of any modifications or changes undertaken solely
on account of this Section 4.02.
 
     SECTION 4.03 Employees; Benefit Plans and Programs.  (a) Each person who is
employed by the Company immediately prior to the Effective Time (a "Company
Employee") shall, at the Effective Time, become an employee (but not an officer)
of the Association. Beginning at the Effective Time, each of the Company
Employees shall serve the Association in the same capacity in which he or she
served the Company immediately prior to the Effective Time and upon the same
terms and conditions generally applicable to other employees of the Association
with comparable positions, with the following special provisions:
 
        (i) If it is not practical to enroll the Company Employees as of the
Effective Time in a particular employee benefit plan or program maintained by
the Association for its employees (the "Association Plans"), the Association
shall continue any comparable plan or program of the Company in effect
immediately prior to the Effective Time (the "Company Plans") for a transition
period. During the transition period, the Company Employees shall continue to
participate in the Company Plans which are continued, and all other employees of
the Association will participate only in the comparable Association Plans.
 
        (ii) The Parent and the Association will amend each of their respective
employee benefit plans and programs to recognize the service of each of the
Company Employees with the Company as service with the Parent and the
Association for all purposes. Each of the Company's tax-qualified plans will be
amended, if necessary, to provide that all benefits accrued by Continuing
Employees through the Effective Time will be fully vested without regard to
their length of service.
 
        (iii) The Association will amend its tax-qualified defined benefit plan
to recognize the service of each of the Company Employees with the Company as
service with the Association for purposes of benefit accrual, with an offset for
vested benefits accrued under the Company's tax-qualified defined benefit plan.
The Company will take all necessary action to amend its tax-qualified defined
benefit plan, effective no later than the Effective Time, to cease all future
benefit accruals.
 
        (iv) If Continuing Employees become eligible to participate in a
medical, dental or health plan of the Parent or the Association, the Parent
shall cause such plan to (A) waive any preexisting condition limitations for
conditions covered under the applicable medical, health or dental plans of the
Company and (B) honor any deductible and out of pocket expenses incurred by the
Continuing Employees and their beneficiaries under such plans during the portion
of the calendar year prior to such participation. If Continuing Employees of the
Company become eligible to participate in a life insurance plan maintained by
the Parent or the Association, Parent shall cause such plan to waive any medical
certification for the Continuing Employees
 
                                      A-30
<PAGE>   149
 
up to the amount of coverage the Continuing Employees had under the life
insurance plan of the Company (but subject to any limits on the maximum amount
of coverage under the life insurance plan of the Parent or the Association).
 
        (v) The Company shall amend its Supplemental Executive Retirement Plan
to provide that amounts includable in the wages of a Company Employee reportable
on IRS Form W-2 as a result of stock option exercises that occur after the date
of execution of this Agreement and payments in settlement of the Company
obligations under any employment agreement or change of control agreement will
not be included as compensation for purposes of benefit accrual under such plan.
The Company shall amend its Supplemental Executive Retirement Plan to cease all
future benefit accruals effective no later than the Effective Time, but such
amendment shall not affect the calculation of any "make-up" payment provided for
under any employment agreement or change in control severance agreement.
 
     (b) (i) The Parent shall assume the obligations of the Company with respect
to the employment agreements between the Company and the persons identified on
the Disclosure Schedule as having such agreements and with respect to the change
in control severance agreements between the Company and the persons identified
in the Disclosure Schedule as having such agreements. The Company shall use
reasonable efforts to secure from each Named Individual and deliver to the
Association within ten (10) business days after the execution of this Agreement
an agreement substantially in the form attached hereto as Exhibit A (the
"Settlement Agreement") to (A) accept as full settlement of his or her rights
in, to and under the Specified Compensation and Benefit Programs the monetary
amount and in-kind benefits reflected for such person on the Disclosure Schedule
and (B) agree to deliver in exchange for such payment and benefits a written
release, substantially in the form attached hereto as Exhibit B (the "Release"),
of any further claim in, to and under the Specified Compensation and Benefit
Programs.
 
        (ii) As soon as practicable following the Effective Time, the Parent
shall pay to each of Messrs. Keegan, Harris and Henchy whose Settlement
Agreement has been timely delivered to the Association the monetary payment and
benefits set forth in Settlement Agreement in exchange for his Release.
 
     (c) The Company shall amend its retirement plan for non-employee directors
to cease all future benefit accruals, and shall terminate its deferred
compensation plan for non-employee directors, in each case effective no later
than the Effective Time, but such amendment shall not prevent the application of
Section 4.4 of the retirement plan for non-employee directors providing for
immediate, unreduced benefits.
 
     (d) Parent shall pay, in accordance with the terms of the 1997 Annual
Incentive Plan, the cash awards provided thereunder based, if applicable, on
performance through the Effective Time or if the Effective Time occurs prior to
September 30, 1997, a pro rata portion of such amount.

Time to the books, records (including, without limitation, tax returns and work

the requirements of law, each of the Parent, the Association and the Company

confidential relationship, (ii) becomes available to such party or an affiliate
of such party from other sources not known by such party to be bound by a
confidentiality obligation or agreement, (iii) is disclosed with the prior
written approval of the other party or (iv) is or becomes readily ascertainable

        (v) the Association shall maintain appropriate insurance satisfactory to
the Company in connection with any work done by the Association's agents and
representatives pursuant to this Section 4.13;
 
        (vi) the Association shall reimburse the Company for any material
out-of-pocket costs or expenses incurred by the Company in connection with this
undertaking; and

material to the financial condition, properties, businesses or results of
operations of the Company and its Subsidiaries taken as a whole to which the
Company or any Subsidiary is a party or is subject; and (b) any event,
condition, change or occurrence which individually or in the aggregate has, or
which, so far as reasonably can be foreseen at the time of its occurrence, is
reasonably likely to result in a Material Adverse Event. Each of the Company and
the Parent shall give prompt notice to the other party of any notice or other
communication from any third party alleging that the consent of such third party
is or may be required in connection with the transactions contemplated by this
Agreement.
 
     SECTION 4.14 Advisory Board.  The Parent shall, promptly following the
Effective Time, cause all of the non-officer members of the Company's Board as
of the date of this Agreement who are willing to so serve to be elected or
appointed as members of an advisory board (the "Advisory Board") established by
the Parent, the function of which shall be to advise the Parent with respect to
deposit and lending activities in the Company's former market area and to
maintain and develop customer relationships. The members of the Advisory Board
who are willing to so serve shall be elected to serve a three year term
beginning on the Effective Date. Each member of the Advisory Board who is not a
director of the Parent and who is not an employee of the Parent shall receive a
retainer fee for such service at an annual rate of $24,000, payable in monthly
installments or in one lump sum at any time in advance at the option of the
Parent. Within 30 days after the Effective Date, each member of the Advisory
Board shall receive a grant of options to purchase 4,000 shares of the Parent
Common Stock which subject to the terms of an option agreement to be provided by
the Parent and reasonably acceptable to the Company shall extend for a term of
ten (10) years beginning on the Effective Date; shall be exercisable at any time
after the Effective Date at an exercise price per share equal to the closing
sales price for a share of Parent Common Stock on the date of grant as reported
in The Wall Street Journal and shall provide for reasonable registration rights.
At or prior to the Effective Time, Parent shall (i) take all corporate action
necessary to reserve for issuance a sufficient number of shares of Parent Common
Stock for delivery upon exercise of options granted in accordance with this
Section and (ii) file a registration statement on Form S-8 (or any successor or
other appropriate form) with respect to the Parent Common Stock subject to such
options. Parent shall use its best efforts to maintain the effectiveness of such
registration statement (and maintain the current status of the prospectus or
prospectuses contained therein) for so long as such Options remain outstanding.
 
     SECTION 4.15 Directors.  The Parent agrees to cause Mr. Gerard C. Keegan
and one other member of the Company's board of directors (on the date hereof)
selected by the Company and acceptable to the Parent,
 
                                      A-34
<PAGE>   153
 
who are willing so to serve ("Former Company Directors"), to be elected or
appointed as directors of the Parent and Association at, or as promptly as
practicable after, the Effective Time (such appointment or election of Former
Company Directors to be as evenly distributed as possible among the classes of
the Parent directors).
 
     SECTION 4.16 Indemnification; Directors' and Officers' Insurance.  (a) From
and after the Effective Time through the sixth anniversary of the Effective
Date, the Parent agrees to indemnify and hold harmless each present and former
director and officer of the Company or its Subsidiaries and each officer or
employee of the Company or its Subsidiaries that is serving or has served as a
director or trustee of another entity expressly at the Company's request or
direction (each, an "Indemnified Party"), against any costs or expenses
(including reasonable attorneys' fees), judgments, fines, losses, claims,
damages or liabilities (collectively, "Costs") incurred in connection with any
claim, action, suit, proceeding or investigation, whether civil, criminal,
administrative or investigative, arising out of matters existing or occurring at
or prior to the Effective Time (including the transactions contemplated by this
Agreement, including the entering into of the Stock Option Agreement), whether
asserted or claimed prior to, at or after the Effective Time, and to advance any
such Costs to each Indemnified Party as they are from time to time incurred, in
each case to the fullest extent then permitted under applicable law.
 
     (b) Any Indemnified Party wishing to claim indemnification under Section
4.16(a), upon learning of any such claim, action, suit, proceeding or
investigation, shall promptly notify the Parent thereof, but the failure to so
notify shall not relieve the Parent of any liability it may have hereunder to
such Indemnified Party if such failure does not materially and substantially
prejudice the indemnifying party. In the event of any such claim, action, suit,
proceeding or investigation, (i) the Parent shall have the right to assume the
defense thereof with counsel reasonably acceptable to the Indemnified Party and
the Parent shall not be liable to such Indemnified Party for any legal expenses
of other counsel subsequently incurred by such Indemnified Party in connection
with the defense thereof, except that if the Parent does not elect to assume
such defense within a reasonable time or counsel for the Indemnified Party at
any time advises that there are issues which raise conflicts of interest between
the Parent and the Indemnified Party, the Indemnified Party may retain counsel
satisfactory to such Indemnified Party, and the Parent shall remain responsible
for the reasonable fees and expenses of such counsel as set forth above, to be
paid promptly as statements therefor are received; provided, however, that the
Parent shall be obligated pursuant to this paragraph (b) to pay for only one
firm of counsel for all Indemnified Parties in any one jurisdiction with respect
to any given claim, action, suit, proceeding or investigation unless the use of
one counsel for such Indemnified Parties would present such counsel with a
conflict of interest; (ii) the Indemnified Party will reasonably cooperate in
the defense of any such matter; and (iii) the Parent shall not be liable for any
settlement effected by an Indemnified Party without its prior written consent,
which consent may not be withheld unless such settlement is unreasonable in
light of such claims, actions, suits, proceedings or investigations against, or
defenses available to, such Indemnified Party.
 
     (c) Parent shall pay all reasonable Costs, including attorneys' fees, that
may be incurred by any Indemnified Party in successfully enforcing the indemnity
and other obligations provided for in this Section 4.16 to the fullest extent
permitted under applicable law. The rights of each Indemnified Party hereunder
shall be in addition to any other rights such Indemnified Party may have under
applicable law.
 
     (d) For a period of six years after the Effective Time, the Parent shall
cause to be maintained in effect the current policies of directors' and
officers' liability insurance maintained by the Company (provided that the
Parent may substitute therefor policies with reputable and financially sound
carriers of at least the same coverage and amount containing terms which are no
less advantageous to the beneficiaries thereof); provided, however, that in no
event shall the Parent be obligated to expend, in order to maintain or provide
insurance coverage pursuant to this Subsection 4.16(d), any premium per annum in
excess of 200% of the amount of the annual premiums paid as of the date hereof
by the Company for such insurance (the "Maximum Agreement"); provided, further,
that if the amount of the annual premiums necessary to maintain or procure such
insurance coverage exceeds the Maximum Amount, the Parent shall maintain the
most advantageous policies of directors' and officers' insurance obtainable for
an annual premium equal to the Maximum Amount; and provided, further, that
officers and directors of the Company may be required to make
 
                                      A-35
<PAGE>   154
 
application and provide customary representations and warranties to the Parent's
insurance carrier for the purpose of obtaining such insurance.
 
     SECTION 4.17 Transition Committee.  The Parent recognizes that the Company
has a talented group of officers and employees that will be important to the
future growth of the combined companies. In recognition of the foregoing,
immediately after the execution of this Agreement, the Parent shall form an
Employee Merger Transition Committee consisting of Mr. George L. Engelke, Jr.
and Mr. Gerard C. Keegan, who shall each serve as co-chairman, and such other
persons, if any, as they shall mutually select. The Employee Merger Transition
Committee shall have sole responsibility for all decisions affecting the
employees of the Company and its Subsidiaries after the Merger.
 
     SECTION 4.18 Series A ESOP Convertible Preferred Stock.  If the
stockholders of the Company and the Parent have each approved the transactions
contemplated hereby and all requisite regulatory approvals have been obtained,
the Company, within 5 business days of receiving a notice (the "Redemptive
Notice") from the Parent that it has waived all conditions to its obligations to
consummate the Merger, shall take all appropriate steps to call the Series A
ESOP Convertible Preferred Stock for redemption as long as, as of the date of
the Redemptive Notice the closing price of the Parent Common Stock is not less
than $34.125; it being understood that there is no obligation to redeem the
Series A Convertible Preferred Stock except as set forth in this Section 4.18.

whole or (ii) on the Parent and its Subsidiaries taken as a whole. None of the

which would have a Material Adverse Effect on (x) the Company and its

     (d) the Parent shall have received an opinion of Thacher Proffitt & Wood,
counsel to the Parent, dated as of the Effective Date in form and substance
customary in transactions of the type contemplated hereby, and reasonably
satisfactory to the Parent, substantially to the effect that on the basis of the
facts, representations and assumptions set forth in such opinion which are
consistent with the state of facts existing at the Effective Time, the Merger
will be treated for Federal income tax purposes as a reorganization within the
meaning of Section 368(a) of the Code and that accordingly:
 
        (i) No gain or loss will be recognized by the Parent, the Association or
the Company as a result of the Merger;
 
        (ii) Except to the extent of any cash received in lieu of a fractional

will be the same as the tax basis of the Company Common Stock surrendered
pursuant to the Merger, reduced by any amount allocable to a fractional share
interest for which cash is received and by the amount of any Cash Consideration
received and increased by any gain recognized on the exchange;
 
        (iv) The holding period of the Parent Stock received by each stockholder
in the Merger will include the holding period of the Company Common Stock

        (vi) The tax basis of the Parent Series A Preferred Stock received by

Parent Series A Preferred Stock in the Merger will be the same as the tax basis
of the Company Series B Preferred Stock surrendered pursuant to the Merger; and
 
        (vii) The holding period of the Parent Series A Preferred Stock received
by each stockholder in the Merger will include the holding period of the Company
Series B Preferred Stock exchanged therefor, provided that such stockholder held
such Company Series B Preferred Stock as a capital asset on the date of the
Merger.

fact and law as Thacher Proffitt & Wood considers appropriate, (i)
representations made at the request of Thacher Proffitt & Wood by

                                  TERMINATION
 
     SECTION 6.01  Termination.  This Agreement may be terminated, and the
Merger abandoned, at or prior to the Effective Date, either before or after its
approval by the stockholders of the Company and the Parent:
 
     (a) by the mutual consent of the Parent and the Company, if the board of
directors of each so determines by vote of a majority of the members of its
entire board;
 
     (b) by the Parent or the Company, if its board of directors so determines
by vote of a majority of the members of its entire board, in the event of (i)
the failure of the stockholders of the Company or the Parent, as the case may
be, to approve the Agreement at its meeting called to consider such approval;
provided, however, that the Company or the Parent, as the case may be, shall
only be entitled to terminate the Agreement pursuant to this clause (i) if it
has complied in all material respects with its obligations under Sections 4.09
and 4.10, or (ii) a material breach by the other party hereto of any
representation, warranty,
 
                                      A-39
<PAGE>   158
 
covenant or agreement contained herein which causes the conditions set forth in
Section 5.02(a) (in the case of termination by the Parent) and Section 5.03(a)
(in the case of the termination by the Company) not to be satisfied and such
breach is not cured within 25 business days after written notice of such breach
is given to the party committing such breach by the other party; or which breach
is not capable of being cured by the date set forth in Section 6.01(d) or any
extension thereof;
 
     (c) by the Parent or the Company by written notice to the other party if
either (i) any approval, consent or waiver of a governmental agency required to
permit consummation of the transactions contemplated hereby shall have been
denied or (ii) any governmental authority of competent jurisdiction shall have
issued a final, unappealable order enjoining or otherwise prohibiting
consummation of the transactions contemplated by this Agreement;
 
     (d) by the Parent or the Company, if its board of directors so determines
by vote of a majority of the members of its entire board, in the event that the
Merger is not consummated by March 31, 1998, unless the failure to so consummate
by such time is due to the breach of any representation, warranty or covenant
contained in this Agreement by the party seeking to terminate; provided, that
such date shall be extended for a period of 30 days following the Valuation
Date, as such term is defined in Section 1.02(a)(iv), in the event the Company
delivers the written notice referred to in Section 6.01(e); or
 
     (e) by the Company, if its board of directors so determines by a majority
vote of members of its entire board, at any time during the five-day period
commencing with the Valuation Date, such termination to be effective on the 30th
day following such Valuation Date (the "Effective Termination Date"), if both of
the following conditions are satisfied:
 
        (i) the Parent Market Value on such Valuation Date of shares of Parent
Common Stock shall be less than an amount equal to $30.30, adjusted as indicated
in the last sentence of this Section 6.01(e); and
 
        (ii) (A) the number (the "Parent Ratio") obtained by dividing the Parent
Market Value on such Valuation Date by $37.88 (the "Initial Parent Market
Value") shall be less than (B) the number obtained by dividing the Final Index
Price by the Initial Index Price and subtracting .15 from the quotient in this
clause (ii)(B) (the "Index Ratio");
 
subject, however, to the following three sentences. If the Company elects to
exercise its termination right pursuant to this Section 6.01(e), it shall give
prompt written notice to the Parent (provided that such notice of election to
terminate may be withdrawn at any time prior to the Effective Termination Date).
During the seven-day period commencing with its receipt of such notice, the
Parent shall have the option to increase the consideration to be received by the
holders of Company Common Stock hereunder, by adjusting the Stock Consideration
to equal the lesser of (x) a number equal to a fraction, the numerator of which
is $15.15 and the denominator of which is the Parent Market Value, and (y) a
number equal to a fraction, the numerator of which is the Index Ratio multiplied
by .50 and the denominator of which is the Parent Ratio. If the Parent so elects
it shall give prompt written notice to the Company of such election and the
revised Stock Consideration, whereupon no termination shall have occurred
pursuant to this Section 6.01(e) and this Agreement shall remain in effect in
accordance with its terms (except as the Stock Consideration shall have been so
modified).
 
     For purposes of this Section 6.01(e), the following terms shall have the
meanings indicated below:
 
        "Final Index Price" means the sum of the Final Prices for each company
comprising the Index Group multiplied by the appropriate weighting.
 
        "Final Price," with respect to any company belonging to the Index Group,
means the average of the daily closing sales prices of a share of common stock
of such company, as reported on the consolidated transaction reporting system
for the market or exchange on which such common stock is principally traded,
during the period of 30 trading days ending on the Valuation Date.
 
        "Index Group" means the 15 financial institution holding companies
listed below, the common stock of all of which shall be publicly traded and as
to which there shall not have been a publicly announced proposal at any time
during the period beginning on the date of this Agreement and ending on the
Valuation Date for any such company to be acquired. In the event that the common
stock of any such company ceases to
 
                                      A-40
<PAGE>   159
 
be publicly traded or a proposal to acquire any such company is announced at any
time during the period beginning on the date of this Agreement and ending on the
Valuation Date, such company will be removed from the Index Group, and the
weights attributed to the remaining companies will be adjusted proportionately
for purposes of determining the Final Index Price and the Initial Index Price.
The 15 financial institution holding companies and the weights attributed to
them are as follows:

        "Initial Index Price" means the sum of each per share closing price of
the common stock of each company comprising the Index Group multiplied by the
applicable weighting, as such prices are reported on the consolidated
transactions reporting system for the market or exchange on which such common
stock is principally traded on the trading day immediately preceding the public
announcement of this Agreement.
 
        "Parent Market Value" shall have the meaning set forth in Section
1.02(a)(iv) hereof.
 
        "Valuation Date" means the Valuation Date, as defined in Section
1.02(a)(iv) hereof.
 
If the Parent or any company belonging to the Index Group declares or effects a
stock dividend, reclassification, recapitalization, split-up, combination,
exchange of shares or similar transaction between the date of this Agreement and
the Valuation Date, the prices for the common stock of such company shall be
appropriately adjusted for the purposes of applying this Section 6.01(e);
 
     (f) by the Parent or the Company if (i) the Board of Directors of the
Company shall have withdrawn or adversely modified its approval or
recommendation of this Agreement at a time when an Acquisition Transaction (as
defined in Section 6.03(b)) has been proposed or (ii) the Board of Directors of
the Parent shall have withdrawn or adversely modified its approval or
recommendation of this Agreement or the Parent has not convened a meeting of
stockholders at which a vote was taken to approve the transactions contemplated
by the Merger prior to the termination of this Agreement pursuant to the terms
hereof. In the event of such termination, the party referred to in clause (i) or
clause (ii), whichever is applicable, shall pay to the other party the
termination fee of five million and 00/100 Dollars ($5,000,000) in cash on
demand in recognition of the efforts, expenses and other opportunities foregone
by the other party while structuring the Merger, and if the Company makes the
payment as set forth herein, it shall have no further obligations to pay any
termination fee pursuant to Section 6.03. Such payment shall have no effect on
the ability of the Parent to exercise its then existing rights, if any, under
the Option Agreement.
 
     SECTION 6.02  Effect of Termination.  In the event of the termination of
this Agreement by either the Parent or the Company, as provided above, this
Agreement shall thereafter become void and, subject to the provisions of Section
8.02, there shall be no liability on the part of any party hereto or their
respective officers or directors, except that any such termination shall be
without prejudice to the rights of any party hereto

arising out of the willful breach by any other party of any covenant or willful
misrepresentation contained in this Agreement.
 
     SECTION 6.03  Third Party Termination Fee.  In recognition of the efforts,
expenses and other opportunities foregone by the Parent while structuring the
Merger, the parties agree that the Company shall pay to the Parent the
termination fee of five million and 00/100 Dollars ($5,000,000) in cash on
demand if, during a period of eighteen (18) months after the date hereof, any of
the following occurs:
 
     (a) the acquisition by any person other than the Parent or an affiliate of
the Parent of beneficial ownership of 20% or more of the then outstanding voting
power of the Company;
 
     (b) the Company or any of its Subsidiaries, without having received the
Parent's prior written consent, shall have entered into an agreement to engage
in an Acquisition Transaction (as defined herein) with any person (the term
"person" for purposes of this Agreement having the meaning assigned thereto in
Sections 3(a)(9) and 13(d)(3) of the Exchange Act and the rules and regulations
thereunder) other than the Parent or any of its Subsidiaries or the Board of
Directors of the Company shall have recommended that the stockholders of the
Company approve or accept any Acquisition Transaction with any person other than
the Parent or any of its Subsidiaries. For purposes of this Agreement,
"Acquisition Transaction" shall mean (x) a merger or consolidation, or any
similar transaction, involving the Company, (y) a purchase, lease or other
acquisition of all or substantially all of the assets of the Company or (z) a
purchase or other acquisition (including by way of merger, consolidation, share
exchange or otherwise) of securities representing 20% or more of the voting
power of the Company; provided, that the term "Acquisition Transaction" does not
include any internal merger or consolidation involving only the Company and/or
its Subsidiaries; or
 
     (c) after a bona fide proposal is made by a third party to the Company or
its stockholders to engage in an Acquisition Transaction, (i) the Company shall
have breached any covenant or obligation contained in the Agreement and such
breach would entitle the Parent to terminate the Agreement or (ii) the holders
of Company stock shall not have approved the Agreement at the meeting of such
stockholders held for the purpose of voting on the Agreement, or such meeting
shall not have been held or shall have been canceled prior to termination of the
Agreement or (iii) the Company's Board of Directors shall have withdrawn or
modified in a manner adverse to the Parent the recommendation of the Company's
Board of Directors with respect to the Agreement.
 
     Any fee payable to the Parent pursuant to this Section 6.03 or Section
6.01(f) shall be reduced dollar for dollar (but shall not be reduced to a
negative number) to the extent that the Total Profit (as defined in the Option
Agreement) exceeds $10,000,000. Notwithstanding the foregoing, the Company shall
not be obligated to pay to the Parent such termination fees in the event that
(i) the Company or Parent validly terminate this Agreement pursuant to Section
6.01(a), 6.01(c) or 6.01(b)(i) if the stockholders of the Parent fail to approve
the transactions contemplated by this Agreement, (ii) the Parent shall have
received the termination fee set forth in Section 6.01(f), (iii) the Company
terminates this Agreement pursuant to Section 6.01(b)(ii) or 6.01(e) or (iv) the
Merger is terminated under Section 6.01(d) as a result of the failure to satisfy
the conditions set forth in Section 5.02(h).

                             STOCK OPTION AGREEMENT
 
     STOCK OPTION AGREEMENT, dated as of March 29, 1997 (the "Agreement"), by
and between The Greater New York Savings Bank, a New York chartered stock
savings bank ("Issuer"), and Astoria Financial Corporation, a Delaware
corporation ("Grantee").
 
                                    RECITALS
 
     A. The Plan.  Grantee, Issuer and the Association have entered into an
Agreement and Plan of Merger, dated as of March 29, 1997 (the "Plan"), providing
for, among other things, the merger of Issuer with and into a wholly-owned
subsidiary of Grantee, with such subsidiary being the surviving corporation.
 
     B. Condition to Plan.  As a condition and an inducement to Grantee's
execution and delivery of the Plan, Grantee has required that Issuer agree, and
Issuer has agreed, to grant Grantee the Option (as hereinafter defined).
 
     NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth herein and in
the Plan, and intending to be legally bound hereby, Issuer and Grantee agree as
follows:
 
     1. Defined Terms.  Capitalized terms which are used but not defined herein
shall have the meanings ascribed to such terms in the Plan.
 
     2. Grant of Option.  Subject to the terms and conditions set forth herein,
Issuer hereby grants to Grantee an irrevocable option (the "Option") to purchase
up to 2,721,536 shares of common stock, par value $1.00 per share ("Issuer
Common Stock"), of Issuer (as adjusted as set forth herein, the "Option Shares,"
which shall include the Option Shares before and after any transfer of such
Option Shares, but in no event shall the number of Option Shares for which this
Option is exercisable exceed 19.9% of the issued and outstanding shares of
Issuer Common Stock), at a purchase price per Option Share (as adjusted as set
forth herein, the "Purchase Price") equal to $17.875. Each Option Share issued
upon exercise of the Option shall be accompanied by the related preferred share
purchase right ("Company Rights") issued pursuant to the Rights Agreement
between the Company and The Chase Manhattan Bank (as successor in interest to
Manufacturers Hanover Trust Company), dated as of June 14, 1990, as amended
("Company Rights Agreement").
 
     3. Exercise of Option.  (a) Provided that (i) Grantee or Holder (as
hereinafter defined), as applicable, shall not be in material breach of the
agreements or covenants contained in this Agreement or the Plan, and (ii) no
preliminary or permanent injunction or other order against the delivery of
shares covered by the Option issued by any court of competent jurisdiction in
the United States shall be in effect, the Holder may exercise the Option, in
whole or in part, at any time and from time to time, following the occurrence of
a Purchase Event (as hereinafter defined); provided that the Option shall
terminate and be of no further force or effect upon the earliest to occur of (A)
the Effective Time, (B) termination of the Plan in accordance with the terms
thereof prior to the occurrence of a Purchase Event or a Preliminary Purchase
Event other than a termination thereof by Grantee pursuant to Section
6.01(b)(ii) of the Plan (a termination of the Plan by Grantee pursuant to
Section 6.01(b)(ii) of the Plan, being referred to herein as a "Default
Termination"), (C) 15 months after a Default Termination or (D) 15 months after
termination of the Plan (other than a Default Termination) following the
occurrence of a Purchase Event or a Preliminary Purchase Event;
 
                                       B-1
<PAGE>   165
 
provided, however, that any purchase of shares upon exercise of the Option shall
be subject to compliance with applicable law. The term "Holder" shall mean the
holder or holders of the Option from time to time, and which initially is
Grantee. The rights set forth in Section 8 of this Agreement shall terminate
when the right to exercise the Option terminates (other than as a result of a
complete exercise of the Option) as set forth herein.
 
     (b) As used herein, a "Purchase Event" means any of the following events:
 
          (i) Without Grantee's prior written consent, Issuer shall have
     recommended, publicly proposed or publicly announced an intention to
     authorize, recommend or propose, or Issuer shall have entered into an
     agreement with any person (other than Grantee or any subsidiary of Grantee)
     to effect (A) a merger, consolidation or similar transaction involving
     Issuer or any of its significant subsidiaries, (B) the disposition, by
     sale, lease, exchange or otherwise, of assets or deposits of Issuer or any
     of its significant subsidiaries representing in either case 25% or more of
     the consolidated assets or deposits of Issuer and its subsidiaries or (C)
     the issuance, sale or other disposition by Issuer of (including by way of
     merger, consolidation, share exchange or any similar transaction)
     securities representing 25% or more of the voting power of Issuer or any of
     its significant subsidiaries, other than, in the case of (A) or (C), any
     transaction involving Issuer or any of its significant subsidiaries in
     which the voting securities of Issuer outstanding immediately prior thereto
     continue to represent (by either remaining outstanding or being converted
     into the voting securities of the surviving entity of any such transaction)
     at least 65% of the combined voting power of the voting securities of the
     Issuer or the surviving entity outstanding immediately after the
     consummation of such transaction (provided any such transaction is not
     violative of the Plan) (each of (A), (B) or (C), an "Acquisition
     Transaction"); or
 
          (ii) Any person (other than Grantee or any subsidiary of Grantee)
     shall have acquired beneficial ownership (as such term is defined in Rule
     13d-3, promulgated under the Securities and Exchange Act of 1934 (the
     "Exchange Act") of, or the right to acquire beneficial ownership of, or any
     "group" (as such term is defined in Section 13(d)(3) of the Exchange Act),
     other than a group of which Grantee or any subsidiary of Grantee is a
     member, shall have been formed which beneficially owns or has the right to
     acquire beneficial ownership of, 20% or more of the voting power of Issuer
     or any of its significant subsidiaries.
 
     (c) As used herein, a "Preliminary Purchase Event" means any of the
following events:
 
          (i) Any person (other than Grantee or any subsidiary of Grantee) shall
     have commenced (as such term is defined in Rule 14d-2, promulgated under
     the Exchange Act) or shall have filed a registration statement under the
     Securities Act of 1933, as amended (the "Securities Act"), with respect to,
     a tender offer or exchange offer to purchase any shares of Issuer Common
     Stock such that, upon consummation of such offer, such person would own or
     control 20% or more of the voting power of Issuer (such an offer being
     referred to herein as a "Tender Offer" or an "Exchange Offer,"
     respectively); or
 
          (ii) The stockholders shall not have approved the Plan by the
     requisite vote at the stockholders meeting of the Issuer called for that
     purpose ("Company Meeting"), the Company Meeting shall not have been held
     or shall have been canceled prior to termination of the Plan or Issuer's
     Board of Directors shall have withdrawn or modified in a manner adverse to
     Grantee the recommendation of Issuer's Board of Directors with respect to
     the Plan, in each case after it shall have been publicly announced that any
     person (other than Grantee or any subsidiary of Grantee) shall have (A)
     made, or disclosed an intention to make, a bona fide proposal to engage in
     an Acquisition Transaction, (B) commenced a Tender Offer or filed a
     registration statement under the Securities Act with respect to an Exchange
     Offer or (C) filed an application (or given a notice), whether in draft or
     final form, under the Home Owners' Loan Act of 1933, as amended, the Bank
     Holding Company Act, as amended, the Bank Merger Act, as amended or the
     Change in Bank Control Act of 1978, as amended, for approval to engage in
     an Acquisition Transaction; or
 
          (iii) Any person (other than Grantee or any subsidiary of Grantee)
     shall have made a bona fide proposal to Issuer or its stockholders by
     public announcement, or written communication that is or becomes the
     subject of public disclosure, to engage in an Acquisition Transaction; or
 
                                       B-2
<PAGE>   166
 
          (iv) After a proposal is made by a third party to Issuer or its
     stockholders to engage in an Acquisition Transaction, or such third party
     states its intention to the Issuer to make such a proposal if the Plan
     terminates, Issuer shall have breached any representation, warranty,
     covenant or agreement contained in the Plan and such breach would entitle
     Grantee to terminate the Plan under Section 6.01(b) thereof (without regard
     to the cure period provided for therein unless such cure is promptly
     effected without jeopardizing consummation of the Merger pursuant to the
     terms of the Plan).
 
     As used in this Agreement, the term "person" shall have the meaning
specified in Sections 3(a)(9) and 13(d)(3) of the Exchange Act.
 
     (d) Issuer shall notify Grantee promptly in writing of the occurrence of
any Preliminary Purchase Event or Purchase Event, it being understood that the
giving of such notice by Issuer shall not be a condition to the right of Holder
to exercise the Option.
 
     (e) In the event Holder wishes to exercise the Option, it shall send to
Issuer a written notice (the "Stock Exercise Notice," the date of which being
herein referred to as the "Notice Date") specifying (i) the total number of
Option Shares it intends to purchase pursuant to such exercise and (ii) a place
and date not earlier than three business days nor later than 15 business days
from the Notice Date for the closing (the "Closing") of such purchase (the
"Closing Date"); provided that the first notice of exercise shall be sent to
Issuer within 180 days after the first Purchase Event of which Grantee has been
notified. If prior notification to or approval of any Regulatory Authority is
required in connection with any such purchase, Issuer shall cooperate with the
Holder in the filing of the required notice of application for approval and the
obtaining of such approval, and the Closing shall occur immediately following
such regulatory approvals and any mandatory waiting periods. Any exercise of the
Option shall be deemed to occur on the Notice Date relating thereto.
 
     4. Payment and Delivery of Certificates.  (a) On each Closing Date, Holder
shall (i) pay to Issuer, in immediately available funds by wire transfer to a
bank account designated by Issuer, an amount equal to the Purchase Price
multiplied by the number of Option Shares to be purchased on such Closing Date
and (ii) present and surrender this Agreement to the Issuer at the address of
the Issuer specified in Section 12(f) of this Agreement.
 
     (b) At each Closing, simultaneously with the delivery of immediately
available funds and surrender of this Agreement as provided in Section 4(a) of
this Agreement, (i) Issuer shall deliver to Holder (A) a certificate or
certificates representing the Option Shares to be purchased at such Closing,
which Option Shares shall be free and clear of all Liens (as defined in the
Plan) and subject to no preemptive rights, and (B) if the Option is exercised in
part only, an executed new agreement with the same terms as this Agreement
evidencing the right to purchase the balance of the shares of Issuer Common
Stock purchasable hereunder, and (ii) Holder shall deliver to Issuer a letter
agreeing that Holder shall not offer to sell or otherwise dispose of such Option
Shares in violation of applicable federal and state law or of the provisions of
this Agreement.
 
     (c) In addition to any other legend that is required by applicable law,
certificates for the Option Shares delivered at each Closing shall be endorsed
with a restrictive legend which shall read substantially as follows:
 
     THE TRANSFER OF THE STOCK REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO
RESTRICTIONS ARISING UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND PURSUANT
TO THE TERMS OF A STOCK OPTION AGREEMENT DATED AS OF MARCH 29, 1997. A COPY OF
SUCH AGREEMENT WILL BE PROVIDED TO THE HOLDER HEREOF WITHOUT CHARGE UPON RECEIPT
BY THE ISSUER OF A WRITTEN REQUEST THEREFOR.
 
It is understood and agreed that the portion of the above legend relating to the
Securities Act shall be removed by delivery of substitute certificate(s) without
such legend if Holder shall have delivered to Issuer a copy of a letter from the
staff of the Securities Exchange Commission (the "SEC"), or an opinion of
counsel in form and substance reasonably satisfactory to Issuer and its counsel,
to the effect that such legend is not required for purposes of the Securities
Act.
 
     (d) Upon the giving by Holder to Issuer of the written notice of exercise
of the Option provided for under Section 3(e) of this Agreement, the tender of
the applicable purchase price in immediately available
 
                                       B-3
<PAGE>   167
 
funds and the tender of this Agreement to Issuer, Holder shall be deemed to be
the holder of record of the shares of Issuer Common Stock issuable upon such
exercise, notwithstanding that the stock transfer books of Issuer shall then be
closed or that certificates representing such shares of Issuer Common Stock
shall not then be actually delivered to Holder. Issuer shall pay all expenses,
and any and all United States federal, state and local taxes and other charges
that may be payable in connection with the preparation, issuance and delivery of
stock certificates under this Section 4 in the name of Holder or its assignee,
transferee or designee.
 
     (e) Issuer agrees (i) that it shall at all times maintain, free from
preemptive rights, sufficient authorized but unissued or treasury shares of
Issuer Common Stock so that the Option may be exercised without additional
authorization of Issuer Common Stock after giving effect to all other options,
warrants, convertible securities and other rights to purchase Issuer Common
Stock, (ii) that it will not, by charter amendment or through reorganization,
consolidation, merger, dissolution or sale of assets, or by any other voluntary
act, avoid or seek to avoid the observance or performance of any of the
covenants, stipulations or conditions to be observed or performed hereunder by
Issuer, (iii) promptly to take all action as may from time to time be required
(including (A) complying with all premerger notification, reporting and waiting
period requirements and (B) in the event prior approval of or notice to any
Regulatory Authority is necessary before the Option may be exercised,
cooperating fully with Holder in preparing such applications or notices and
providing such information to such Regulatory Authority as it may require) in
order to permit Holder to exercise the Option and Issuer duly and effectively to
issue shares of the Issuer Common Stock pursuant hereto and (iv) promptly to
take all action provided herein to protect the rights of Holder against
dilution.
 
     5. Representations and Warranties of Issuer.  Issuer hereby represents and
warrants to Grantee (and Holder, if different than Grantee) as follows:
 
          (a) Corporate Authority.  Issuer has full corporate power and
     authority to execute and deliver this Agreement and to consummate the
     transactions contemplated hereby; the execution and delivery of this
     Agreement and the consummation of the transactions contemplated hereby have
     been duly and validly authorized by the Board of Directors of Issuer, and
     no other corporate proceedings on the part of Issuer are necessary to
     authorize this Agreement or to consummate the transactions so contemplated;
     this Agreement has been duly and validly executed and delivered by Issuer.
 
          (b) Beneficial Ownership.  To the best knowledge of Issuer, as of the
     date of this Agreement, no person or group has beneficial ownership of more
     than 15% of the issued and outstanding shares of Issuer Common Stock.
 
          (c) Shares Reserved for Issuance; Capital Stock.  Issuer has taken all
     necessary corporate action to authorize and reserve and permit it to issue,
     and at all times from the date hereof through the termination of this
     Agreement in accordance with its terms, will have reserved for issuance
     upon the exercise of the Option, that number of shares of Issuer Common
     Stock equal to the maximum number of shares of Issuer Common Stock at any
     time and from time to time purchasable upon exercise of the Option, and all
     such shares, upon issuance pursuant to the Option, will be duly authorized,
     validly issued, fully paid and nonassessable, and will be delivered free
     and clear of all claims, liens, encumbrances and security interests (other
     than those created by this Agreement) and not subject to any preemptive
     rights.
 
          (d) No Violations.  The execution, delivery and performance of this
     Agreement does not and will not, and the consummation by Issuer of any of
     the transactions contemplated hereby will not, constitute or result in (i)
     a breach or violation of, or a default under, its certificate of
     incorporation or bylaws, or the comparable governing instruments of any of
     its subsidiaries, or (ii) a breach or violation of, or a default under, any
     agreement, lease, contract, note, mortgage, indenture, arrangement or other
     obligation of it or any of its subsidiaries (with or without the giving of
     notice, the lapse of time or both) or under any law, rule, ordinance or
     regulation or judgment, decree, order, award or governmental or
     non-governmental permit or license to which it or any of its subsidiaries
     is subject, that would, in any case, give any other person the ability to
     prevent or enjoin Issuer's performance under this Agreement in any material
     respect.
 
     6. Representations and Warranties of Grantee.  Grantee hereby represents
and warrants to Issuer that Grantee has full corporate power and authority to
enter into this Agreement and, subject to obtaining the
 
                                       B-4
<PAGE>   168
 
approvals referred to in this Agreement, to consummate the transactions
contemplated by this Agreement; the execution and delivery of this Agreement and
the consummation of the transactions contemplated hereby have been duly
authorized by all necessary corporate action on the part of Grantee; and this
Agreement has been duly executed and delivered by Grantee.
 
     7. Adjustment upon Changes in Issuer Capitalization, Etc.  (a) In the event
of any change in Issuer Common Stock by reason of a stock dividend, stock split,
split-up, recapitalization, combination, exchange of shares, exercise of the
Company Rights or similar transaction, the type and number of shares or
securities subject to the Option, and the Purchase Price therefor, shall be
adjusted appropriately, and proper provision shall be made in the agreements
governing any such transaction so that Holder shall receive, upon exercise of
the Option, the number and class of shares or other securities or property that
Holder would have received in respect of Issuer Common Stock if the Option had
been exercised immediately prior to such event, or the record date therefor, as
applicable. If any additional shares of Issuer Common Stock are issued after the
date of this Agreement (other than pursuant to an event described in the first
sentence of this Section 7(a), upon exercise of any option to purchase Issuer
Common Stock outstanding on the date hereof or upon conversion into Issuer
Common Stock of any convertible security of Issuer outstanding on the date
hereof), the number of shares of Issuer Common Stock subject to the Option shall
be adjusted so that, after such issuance, it, together with any shares of Issuer
Common Stock previously issued pursuant hereto, equals 19.9% of the number of
shares of Issuer Common Stock then issued and outstanding, without giving effect
to any shares subject to or issued pursuant to the Option. No provision of this
Section 7 shall be deemed to affect or change, or constitute authorization for
any violation of, any of the covenants or representations in the Plan.
 
     (b) In the event that Issuer shall enter into an agreement (i) to
consolidate with or merge into any person, other than Grantee or one of its
subsidiaries, and Issuer shall not be the continuing or surviving corporation of
such consolidation or merger, (ii) to permit any person, other than Grantee or
one of its subsidiaries, to merge into Issuer and Issuer shall be the continuing
or surviving corporation, but, in connection with such merger, the then
outstanding shares of Issuer Common Stock shall be changed into or exchanged for
stock or other securities of Issuer or any other person or cash or any other
property, or the outstanding shares of Issuer Common Stock immediately prior to
such merger shall after such merger represent less than 50% of the outstanding
shares and share equivalents of the merged company, or (iii) to sell or
otherwise transfer all or substantially all of its assets or deposits to any
person, other than Grantee or one of its subsidiaries, then, and in each such
case, the agreement governing such transaction shall make proper provisions so
that the Option shall, upon the consummation of any such transaction and upon
the terms and conditions set forth herein, be converted into, or exchanged for,
an option (the "Substitute Option"), at the election of Holder, of either (A)
the Acquiring Corporation (as hereinafter defined), (B) any person that controls
the Acquiring Corporation or (C) in the case of a merger described in clause
(ii), Issuer (such person being referred to as "Substitute Option Issuer").
 
     (c) The Substitute Option shall have the same terms as the Option,
provided, that, if the terms of the Substitute Option cannot, for legal reasons,
be the same as the Option, such terms shall be as similar as possible and in no
event less advantageous to Holder. Substitute Option Issuer shall also enter
into an agreement with Holder in substantially the same form as this Agreement,
which shall be applicable to the Substitute Option.
 
     (d) The Substitute Option shall be exercisable for such number of shares of
Substitute Common Stock (as hereinafter defined) as is equal to the Assigned
Value (as hereinafter defined) multiplied by the number of shares of Issuer
Common Stock for which the Option was theretofore exercisable, divided by the
Average Price (as hereinafter defined). The exercise price of the Substitute
Option per share of Substitute Common Stock (the "Substitute Option Price")
shall then be equal to the Purchase Price multiplied by a fraction in which the
numerator is the number of shares of Issuer Common Stock for which the Option
was theretofore exercisable and the denominator is the number of shares of the
Substitute Common Stock for which the Substitute Option is exercisable.
 
     (e) The following terms have the meanings indicated:
 
          (i) "Acquiring Corporation" shall mean (A) the continuing or surviving
     corporation of a consolidation or merger with Issuer (if other than
     Issuer), (B) Issuer in a merger in which Issuer is the continuing
 
                                       B-5
<PAGE>   169
 
     or surviving person, or (C) the transferee of all or substantially all of
     Issuer's assets (or a substantial part of the assets of its subsidiaries
     taken as a whole).
 
          (ii) "Substitute Common Stock" shall mean the shares of capital stock
     (or similar equity interest) with the greatest voting power in respect of
     the election of directors (or persons similarly responsible for the
     direction of the business and affairs) of the Substitute Option Issuer.
 
          (iii) "Assigned Value" shall mean the highest of (A) the price per
     share of Issuer Common Stock at which a Tender Offer or an Exchange Offer
     therefor has been made, (B) the price per share of Issuer Common Stock to
     be paid by any third party pursuant to an agreement with Issuer, (C) the
     highest closing price for shares of Issuer Common Stock within the
     six-month period immediately preceding the consolidation, merger or sale in
     question and (D) in the event of a sale of all or substantially all of
     Issuer's assets or deposits, an amount equal to (x) the sum of the price
     paid in such sale for such assets (and/or deposits) and the current market
     value of the remaining assets of Issuer, as determined by a nationally
     recognized investment banking firm selected by Holder, divided by (y) the
     number of shares of Issuer Common Stock outstanding at such time. In the
     event that a Tender Offer or an Exchange Offer is made for Issuer Common
     Stock or an agreement is entered into for a merger or consolidation
     involving consideration other than cash, the value of the securities or
     other property issuable or deliverable in exchange for Issuer Common Stock
     shall be determined by a nationally recognized investment banking firm
     selected by Holder.
 
          (iv) "Average Price" shall mean the average closing price of a share
     of Substitute Common Stock for the one year immediately preceding the
     consolidation, merger or sale in question, but in no event higher than the
     closing price of the shares of Substitute Common Stock on the day preceding
     such consolidation, merger or sale; provided, that, if Issuer is the issuer
     of the Substitute Option, the Average Price shall be computed with respect
     to a share of common stock issued by Issuer, the person merging into Issuer
     or by any company which controls such person, as Holder may elect.
 
     (f) In no event, pursuant to any of the foregoing paragraphs, shall the
Substitute Option be exercisable for more than 19.9% of the aggregate of the
shares of Substitute Common Stock outstanding prior to exercise of the
Substitute Option. In the event that the Substitute Option would be exercisable
for more than 19.9% of the aggregate of the shares of Substitute Common Stock
but for the limitation in the first sentence of this Section 7(f), Substitute
Option Issuer shall make a cash payment to Holder equal to the excess of (i) the
value of the Substitute Option without giving effect to the limitation in the
first sentence of this Section 7(f) over (ii) the value of the Substitute Option
after giving effect to the limitation in the first sentence of this Section
7(f). This difference in value shall be determined by a nationally recognized
investment banking firm selected by Holder.
 
     (g) Issuer shall not enter into any transaction described in Section 7(b)
of this Agreement unless the Acquiring Corporation and any person that controls
the Acquiring Corporation assume in writing all the obligations of Issuer
hereunder and take all other actions that may be necessary so that the
provisions of this Section 7 are given full force and effect (including, without
limitation, any action that may be necessary so that the holders of the other
shares of common stock issued by Substitute Option Issuer are not entitled to
exercise any rights by reason of the issuance or exercise of the Substitute
Option and the shares of Substitute Common Stock are otherwise in no way
distinguishable from or have lesser economic value (other than any diminution in
value resulting from the fact that the shares Substitute Common Stock are
restricted securities, as defined in Rule 144, promulgated under the Securities
Act ("Rule 144"), or any successor provision) than other shares of common stock
issued by Substitute Option Issuer).
 
     (h) Notwithstanding anything herein to the contrary and in lieu of any
other adjustments provided for herein, in the event that the Issuer completes a
reorganization involving the formation of a holding company for the Issuer, the
agreement governing such transaction shall make proper provisions so that the
Option shall, upon the consummation of any such transaction and upon the terms
and conditions set forth herein, be converted into, or exchanged for, an option
of such holding company with terms substantially identical to those contained
herein.
 
                                       B-6

     8. Repurchase at the Option of Holder.  (a) Subject to the last sentence of
Section 3(a) of this Agreement, at the request of Holder at any time commencing
upon the first occurrence of a Repurchase Event (as defined in Section 8(d)
hereof) and ending 12 months immediately thereafter, Issuer shall repurchase
from Holder (i) the Option and (ii) all shares of Issuer Common Stock purchased
by Holder pursuant hereto with respect to which Holder then has beneficial
ownership. The date on which Holder exercises its rights under this Section 8 is
referred to as the "Request Date." Such repurchase shall be at an aggregate
price (the "Section 8 Repurchase Consideration") equal to the sum of:
 
          (i) The aggregate Purchase Price paid by Holder for any shares of
     Issuer Common Stock acquired pursuant to the Option with respect to which
     Holder then has beneficial ownership;
 
          (ii) The excess, if any, of (A) the Applicable Price (as defined
     below) for each share of Issuer Common Stock over (B) the Purchase Price
     (subject to adjustment pursuant to Section 7 of this Agreement), multiplied
     by the number of shares of Issuer Common Stock with respect to which the
     Option has not been exercised; and
 
          (iii) The excess, if any, of the Applicable Price over the Purchase
     Price (subject to adjustment pursuant to Section 7 of this Agreement) paid
     (or, in the case of Option Shares with respect to which the Option has been
     exercised but the Closing Date has not occurred, payable) by Holder for
     each share of Issuer Common Stock with respect to which the Option has been
     exercised and with respect to which Holder then has beneficial ownership,
     multiplied by the number of such shares.
 
     (b) If Holder exercises its rights under this Section 8, Issuer shall,
within 10 business days after the Request Date, pay the Section 8 Repurchase
Consideration to Holder in immediately available funds, and contemporaneously
with such payment, Holder shall surrender to Issuer the Option and the
certificates evidencing the shares of Issuer Common Stock purchased thereunder
with respect to which Holder then has beneficial ownership, and Holder shall
warrant that it has sole record and beneficial ownership of such shares and that
the same are then free and clear of all Liens. Notwithstanding the foregoing, to
the extent that prior notification to or approval of any Regulatory Authority is
required in connection with the payment of all or any portion of the Section 8
Repurchase Consideration, Holder shall have the ongoing option to revoke its
request for repurchase pursuant to this Section 8, in whole or in part, or to
require that Issuer deliver from time to time that portion of the Section 8
Repurchase Consideration that it is not then so prohibited from paying and
promptly file the required notice or application for approval and expeditiously
process the same (and each party shall cooperate with the other in the filing of
any such notice or application and the obtaining of any such approval). If any
Regulatory Authority disapproves of any part of Issuer's proposed repurchase
pursuant to this Section 8, Issuer shall promptly give notice of such fact to
Holder and Holder shall have the right (i) to revoke the repurchase request or
(ii) to the extent permitted by such Regulatory Authority, determine whether the
repurchase should apply to the Option and/or Option Shares and to what extent to
each, and Holder shall thereupon have the right to exercise the Option as to the
number of Option Shares for which the Option was exercisable at the Request Date
less the number of shares covered by the Option in respect of which payment has
been made pursuant to Section 8(a)(ii) of this Agreement. Holder shall notify
Issuer of its determination under the preceding sentence within five business
days of receipt of notice of disapproval of the repurchase. Notwithstanding
anything herein to the contrary, in the event that Issuer delivers to the Holder
written notice accompanied by a certification of Issuer's independent auditor
each stating that a requested repurchase of the Option or Issuer Common Stock
would result in the recapture of Issuer's bad debt reserves under the Internal
Revenue Code of 1986, as amended, Holder's repurchase request shall be deemed to
be automatically revoked and be of no effect.
 
     Notwithstanding anything herein to the contrary, all of Holder's rights
under this Section 8 shall terminate on the date of termination of this Option
pursuant to Section 3(a) of this Agreement.
 
     (c) For purposes of this Agreement, the "Applicable Price" means the
highest of (i) the highest price per share of Issuer Common Stock paid for any
such share by the person or groups described in Section 8(d)(i) hereof, (ii) the
price per share of Issuer Common Stock received by holders of Issuer Common
Stock in connection with any merger, sale or other business combination
transaction described in Section 7(b)(i), 7(b)(ii) or 7(b)(iii) of this
Agreement, or (iii) the highest closing sales price per share of
 
                                       B-7
<PAGE>   171
 
Issuer Common Stock quoted on the Nasdaq (or if Issuer Common Stock is not
quoted on the Nasdaq, the highest bid price per share as quoted on the principal
trading market or securities exchange on which such shares are traded as
reported by a recognized source chosen by Holder) during the 40 business days
preceding the Request Date; provided, however, that in the event of a sale of
less than all of Issuer's assets, the Applicable Price shall be the sum of the
price paid in such sale for such assets and the current market value of the
remaining assets of Issuer as determined by a nationally recognized investment
banking firm selected by Holder, divided by the number of shares of the Issuer
Common Stock outstanding at the time of such sale. If the consideration to be
offered, paid or received pursuant to either of the foregoing clauses (i) or
(ii) shall be other than in cash, the value of such consideration shall be
determined in good faith by an independent nationally recognized investment
banking firm selected by Holder and reasonably acceptable to Issuer, which
determination shall be conclusive for all purposes of this Agreement.
 
     (d) As used herein, "Repurchase Event" shall occur if (i) any person (other
than Grantee or any subsidiary of Grantee) shall have acquired beneficial
ownership of (as such term is defined in Rule 13d-3, promulgated under the
Exchange Act), or the right to acquire beneficial ownership of, or any "group"
(as such term is defined under the Exchange Act) shall have been formed which
beneficially owns or has the right to acquire beneficial ownership of, 50% or
more of the then outstanding shares of Issuer Common Stock, or (ii) any of the
transactions described in Section 7(b)(i), 7(b)(ii) or 7(b)(iii) of this
Agreement shall be consummated.
 
     9. Registration Rights.  (a) Demand Registration Rights.  Issuer shall,
subject to the conditions of Section 9(c) of this Agreement, if requested by any
Holder, including Grantee and any permitted transferee ("Selling Shareholder"),
as expeditiously as possible, prepare and file a registration statement under
the Securities Act or equivalent statements under the rules and regulations of
the Federal Deposit Insurance Corporation ("FDIC") or the Banking Law of the
State of New York ("NYBL"), as applicable, if such registration is necessary in
order to permit the sale or other disposition of any or all shares of Issuer
Common Stock or other securities that have been acquired by or are issuable to
the Selling Shareholder upon exercise of the Option in accordance with the
intended method of sale or other disposition stated by the Selling Shareholder
in such request, including without limitation a "shelf" registration statement
under Rule 415, promulgated under the Securities Act, or any successor
provision, and Issuer shall use its best efforts to qualify such shares or other
securities for sale under any applicable state securities laws.
 
     (b) Additional Registration Rights.  If Issuer at any time after the
exercise of the Option proposes to register any shares of Issuer Common Stock
under the Securities Act, the NYBL or the rules and regulations of the FDIC in
connection with an underwritten public offering of such Issuer Common Stock,
Issuer will promptly give written notice to the Selling Shareholders of its
intention to do so and, upon the written request of any Selling Shareholder
given within 30 days after receipt of any such notice (which request shall
specify the number of shares of Issuer Common Stock intended to be included in
such underwritten public offering by the Selling Shareholder), Issuer will cause
all such shares for which a Selling Shareholder requests participation in such
registration, to be so registered and included in such underwritten public
offering; provided, however, that Issuer may elect to not cause any such shares
to be so registered (i) if the underwriters in good faith object for valid
business reasons, or (ii) in the case of a registration solely to implement an
employee benefit plan or a registration filed on Form S-4 of the Securities Act
or any equivalent or successor Form; provided, further, however, that such
election pursuant to (i) may only be made two times. If some, but not all the
shares of Issuer Common Stock, with respect to which Issuer shall have received
requests for registration pursuant to this Section 9(b), shall be excluded from
such registration, Issuer shall make appropriate allocation of shares to be
registered among the Selling Shareholders desiring to register their shares pro
rata in the proportion that the number of shares requested to be registered by
each such Selling Shareholder bears to the total number of shares requested to
be registered by all such Selling Shareholders then desiring to have Issuer
Common Stock registered for sale.

     (c) Conditions to Required Registration.  Issuer shall use all reasonable
efforts to cause each registration statement referred to in Section 9(a) of this
Agreement to become effective and to obtain all consents or waivers of other
parties which are required therefor and to keep such registration statement
effective, provided, however, that Issuer may delay any registration of Option
Shares required pursuant to Section 9(a) of this Agreement for a period not
exceeding 90 days provided Issuer shall in good faith determine that any such
registration would adversely affect an offering or contemplated offering of
other securities by Issuer, and Issuer shall not be required to register Option
Shares under the Securities Act pursuant to Section 9(a) hereof:
 
          (i) Prior to the earliest of (A) termination of the Plan pursuant to
     Article VI thereof, (B) failure to obtain the requisite stockholder
     approval pursuant to Section 6.01 of Article VI of the Plan, and (C) a
     Purchase Event or a Preliminary Purchase Event;
 
          (ii) On more than one occasion during any calendar year;
 
          (iii) Within 90 days after the effective date of a registration
     referred to in Section 9(b) of this Agreement pursuant to which the Selling
     Shareholder or Selling Shareholders concerned were afforded the opportunity
     to register such shares under the Securities Act and such shares were
     registered as requested; and
 
          (iv) Unless a request therefor is made to Issuer by Selling
     Shareholders that hold at least 25% or more of the aggregate number of
     Option Shares (including shares of Issuer Common Stock issuable upon
     exercise of the Option) then outstanding.
 
     In addition to the foregoing, Issuer shall not be required to maintain the
effectiveness of any registration statement after the expiration of nine months
from the effective date of such registration statement. Issuer shall use all
reasonable efforts to make any filings, and take all steps, under all applicable
state securities laws to the extent necessary to permit the sale or other
disposition of the Option Shares so registered in accordance with the intended
method of distribution for such shares; provided, however, that Issuer shall not
be required to consent to general jurisdiction or qualify to do business in any
state where it is not otherwise required to so consent to such jurisdiction or
to so qualify to do business.
 
     (d) Expenses.  Except where applicable state law prohibits such payments,
Issuer will pay all expenses (including without limitation registration fees,
qualification fees, blue sky fees and expenses (including the fees and expenses
of counsel), legal expenses, including the reasonable fees and expenses of one
counsel to the holders whose Option Shares are being registered, printing
expenses and the costs of special audits or "cold comfort" letters, expenses of
underwriters, excluding discounts and commissions but including liability
insurance if Issuer so desires or the underwriters so require, and the
reasonable fees and expenses of any necessary special experts) in connection
with each registration pursuant to Section 9(a) or 9(b) of this Agreement
(including the related offerings and sales by holders of Option Shares) and all
other qualifications, notifications or exemptions pursuant to Section 9(a) or
9(b) of this Agreement.
 
     (e) Indemnification.  In connection with any registration under Section
9(a) or 9(b) of this Agreement, Issuer hereby indemnifies the Selling
Shareholders, and each underwriter thereof, including each person, if any, who
controls such holder or underwriter within the meaning of Section 15 of the
Securities Act, against all expenses, losses, claims, damages and liabilities
caused by any untrue, or alleged untrue, statement of a material fact contained
in any registration statement or prospectus or notification or offering circular
(including any amendments or supplements thereto) or any preliminary prospectus,
or caused by any omission, or alleged omission, to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, except insofar as such expenses, losses, claims, damages or
liabilities of such indemnified party are caused by any untrue statement or
alleged untrue statement that was included by Issuer in any such registration
statement or prospectus or notification or offering circular (including any
amendments or supplements thereto) in reliance upon and in conformity with,
information furnished in writing to Issuer by such indemnified party expressly
for use therein, and Issuer and each officer, director and controlling person of
Issuer shall be indemnified by such Selling Shareholders, or by such
underwriter, as the case may be, for all such expenses, losses, claims, damages
and liabilities caused by any untrue, or alleged untrue, statement, that was
included by Issuer in any such registration statement or
 
                                       B-9
<PAGE>   173
 
prospectus or notification or offering circular (including any amendments or
supplements thereto) in reliance upon, and in conformity with, information
furnished in writing to Issuer by such holder or such underwriter, as the case
may be, expressly for such use.
 
     Promptly upon receipt by a party indemnified under this Section 9(e) of
notice of the commencement of any action against such indemnified party in
respect of which indemnity or reimbursement may be sought against any
indemnifying party under this Section 9(e), such indemnified party shall notify
the indemnifying party in writing of the commencement of such action, but the
failure so to notify the indemnifying party shall not relieve it of any
liability which it may otherwise have to any indemnified party under this
Section 9(e). In case notice of commencement of any such action shall be given
to the indemnifying party as above provided, the indemnifying party shall be
entitled to participate in and, to the extent it may wish, jointly with any
other indemnifying party similarly notified, to assume the defense of such
action at its own expense, with counsel chosen by it and satisfactory to such
indemnified party. The indemnified party shall have the right to employ separate
counsel in any such action and participate in the defense thereof, but the fees
and expenses of such counsel (other than reasonable costs of investigation)
shall be paid by the indemnified party unless (i) the indemnifying party either
agrees to pay the same, (ii) the indemnifying party fails to assume the defense
of such action with counsel satisfactory to the indemnified party, or (iii) the
indemnified party has been advised by counsel that one or more legal defenses
may be available to the indemnifying party that may be contrary to the interest
of the indemnified party, in which case the indemnifying party shall be entitled
to assume the defense of such action notwithstanding its obligation to bear fees
and expenses of such counsel. No indemnifying party shall be liable for any
settlement entered into without its consent, which consent may not be
unreasonably withheld.
 
     If the indemnification provided for in this Section 9(e) is unavailable to
a party otherwise entitled to be indemnified in respect of any expenses, losses,
claims, damages or liabilities referred to herein, then the indemnifying party,
in lieu of indemnifying such party otherwise entitled to be indemnified, shall
contribute to the amount paid or payable by such party to be indemnified as a
result of such expenses, losses, claims, damages or liabilities in such
proportion as is appropriate to reflect the relative benefits received by
Issuer, the Selling Shareholders and the underwriters from the offering of the
securities and also the relative fault of Issuer, the Selling Shareholders and
the underwriters in connection with the statements or omissions which resulted
in such expenses, losses, claims, damages or liabilities, as well as any other
relevant equitable considerations. The amount paid or payable by a party as a
result of the expenses, losses, claims, damages and liabilities referred to
above shall be deemed to include any legal or other fees or expenses reasonably
incurred by such party in connection with investigating or defending any action
or claim; provided, however, that in no case shall any Selling Shareholder be
responsible, in the aggregate, for any amount in excess of the net offering
proceeds attributable to its Option Shares included in the offering. No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation. Any obligation by any holder to
indemnify shall be several and not joint with other holders.
 
     In connection with any registration pursuant to Section 9(a) or 9(b) of
this Agreement, Issuer and each Selling Shareholder (other than Grantee) shall
enter into an agreement containing the indemnification provisions of Section
9(e) of this Agreement.
 
     (f) Miscellaneous Reporting.  Issuer shall comply with all reporting
requirements and will do all such other things as may be necessary to permit the
expeditious sale at any time of any Option Shares by the Selling Shareholders
thereof in accordance with and to the extent permitted by any rule or regulation
promulgated by the SEC from time to time, including, without limitation, Rule
144. Issuer shall at its expense provide the Selling Shareholders with any
information necessary in connection with the completion and filing of any
reports or forms required to be filed by them under the Securities Act or the
Exchange Act, or required pursuant to any state securities laws or the rules of
any stock exchange.
 
     (g) Issue Taxes.  Issuer will pay all stamp taxes in connection with the
issuance and the sale of the Option Shares and in connection with the exercise
of the Option, and will save the Selling Shareholders harmless, without
limitation as to time, against any and all liabilities, with respect to all such
taxes.

<PAGE>   174
 
     10. Quotation; Listing.  If Issuer Common Stock or any other securities to
be acquired in connection with the exercise of the Option are then authorized
for quotation or trading or listing on the Nasdaq or any securities exchange,
Issuer, upon the request of Holder, will promptly file an application, if
required, to authorize for quotation or trading or listing the shares of Issuer
Common Stock or other securities to be acquired upon exercise of the Option on
the Nasdaq or such other securities exchange and will use its best efforts to
obtain approval, if required, of such quotation or listing as soon as
practicable.
 
     11. Division of Option.  This Agreement (and the Option granted hereby) are
exchangeable, without expense, at the option of Holder, upon presentation and
surrender of this Agreement at the principal office of Issuer for other
Agreements providing for Options of different denominations entitling the holder
thereof to purchase in the aggregate the same number of shares of Issuer Common
Stock purchasable hereunder. The terms "Agreement" and "Option" as used herein
include any other Agreements and related Options for which this Agreement (and
the Option granted hereby) may be exchanged. Upon receipt by Issuer of evidence
reasonably satisfactory to it of the loss, theft, destruction or mutilation of
this Agreement, and (in the case of loss, theft or destruction) of reasonably
satisfactory indemnification, and upon surrender and cancellation of this
Agreement, if mutilated, Issuer will execute and deliver a new Agreement of like
tenor and date. Any such new Agreement executed and delivered shall constitute
an additional contractual obligation on the part of Issuer, whether or not the
Agreement so lost, stolen, destroyed or mutilated shall at any time be
enforceable by anyone.
 
     12. Profit Limitation.  (a) Notwithstanding any other provision of this
Agreement, in no event shall the Grantee's Total Profit (as hereinafter defined)
exceed $10 million and, if it otherwise would exceed such amount, the Grantee,
at its sole election, shall either (a) deliver to the Issuer for cancellation
Shares previously purchased by Grantee, (b) pay cash or other consideration to
the Issuer or (c) undertake any combination thereof, so that Grantee's Total
Profit shall not exceed $10 million after taking into account the foregoing
actions.
 
     (b) Notwithstanding any other provision of this Agreement, this Option may
not be exercised for a number of Shares as would, as of the Notice Date, result
in a Notional Total Profit (as defined below) of more than $10 million and, if
exercise of the Option otherwise would exceed such amount, the Grantee, at its
discretion, may increase the Purchase Price for that number of Shares set forth
in the Stock Exercise Notice so that the Notional Total Profit shall not exceed
$10 million; provided, that nothing in this sentence shall restrict any exercise
of the Option permitted hereby on any subsequent date at the Purchase Price set
forth in Section 2 hereof.
 
     (c) As used herein, the term "Total Profit" shall mean the aggregate amount
(before taxes) of the following: (i) the amount of cash received by Grantee
pursuant to Section 6.01(f) or 6.03 of the Merger Agreement and Section 8(a)(ii)
hereof, (ii) (x) the amount received by Grantee pursuant to the Issuer's
repurchase of Option Shares pursuant to Section 8 hereof, less (y) the Grantee's
purchase price for such Option Shares, and (iii) (x) the net cash amounts
received by Grantee pursuant to the sale of Option Shares (or any other
securities into which such Option Shares are converted or exchanged) to any
unaffiliated party, less (y) the Grantee's purchase price for such Option
Shares.
 
     (d) As used herein, the term "Notional Total Profit" with respect to any
number of Option Shares as to which Grantee may propose to exercise this Option
shall be the Total Profit determined as of the date of the Stock Exercise Notice
assuming that this Option was exercised on such date for such number of Shares
and assuming that such Option Shares, together with all other Option Shares held
by Grantee and its affiliates as of such date, were sold for cash at the closing
market price for the Common Stock as of the close of business on the preceding
trading day (less customary brokerage commissions).
 
     13. Miscellaneous.  (a) Expenses.  Each of the parties hereto shall bear
and pay all costs and expenses incurred by it or on its behalf in connection
with the transactions contemplated hereunder, including fees and expenses of its
own financial consultants, investment bankers, accountants and counsel.
 
                                      B-11

     (b) Waiver and Amendment.  Any provision of this Agreement may be waived at
any time by the party that is entitled to the benefits of such provision. This
Agreement may not be modified, amended, altered or supplemented except upon the
execution and delivery of a written agreement executed by the parties hereto.
 
     (c) Entire Agreement: No Third-Party Beneficiaries; Severability.  This
Agreement, together with the Plan and the other documents and instruments
referred to herein and therein, between Grantee and Issuer (i) constitutes the
entire agreement and supersedes all prior agreements and understandings, both
written and oral, between the parties with respect to the subject matter hereof
and (ii) is not intended to confer upon any person other than the parties hereto
(other than the indemnified parties under Section 9(e) of this Agreement and any
transferees of the Option Shares or any permitted transferee of this Agreement
pursuant to Section 12(h) of this Agreement) any rights or remedies hereunder.
If any term, provision, covenant or restriction of this Agreement is held by a
court of competent jurisdiction or Regulatory Authority to be invalid, void or
unenforceable, the remainder of the terms, provisions, covenants and
restrictions of this Agreement shall remain in full force and effect and shall
in no way be affected, impaired or invalidated. If for any reason such court or
Regulatory Authority determines that the Option does not permit Holder to
acquire, or does not require Issuer to repurchase, the full number of shares of
Issuer Common Stock as provided in Section 3 of this Agreement (as may be
adjusted herein), it is the express intention of Issuer to allow Holder to
acquire or to require Issuer to repurchase such lesser number of shares as may
be permissible without any amendment or modification hereof.
 
     (d) Governing Law.  This Agreement shall be governed and construed in
accordance with the laws of the State of New York without regard to any
applicable conflicts of law rules.
 
     (e) Descriptive Headings.  The descriptive headings contained herein are
for convenience of reference only and shall not affect in any way the meaning or
interpretation of this Agreement.
 
     (f) Notices.  All notices and other communications hereunder shall be in
writing and shall be deemed given if delivered personally, telecopied (with
confirmation) or mailed by registered or certified mail (return receipt
requested) to the parties at the addresses set forth in the Plan (or at such
other address for a party as shall be specified by like notice).
 
     (g) Counterparts.  This Agreement and any amendments hereto may be executed
in two counterparts, each of which shall be considered one and the same
agreement and shall become effective when both counterparts have been signed, it
being understood that both parties need not sign the same counterpart.
 
     (h) Assignment.  Neither this Agreement nor any of the rights, interests or
obligations hereunder or under the Option shall be assigned by any of the
parties hereto (whether by operation of law or otherwise) without the prior
written consent of the other party, except that Holder may assign this Agreement
to a wholly-owned subsidiary of Holder and Holder may assign its rights
hereunder in whole or in part after the occurrence of a Purchase Event. Subject
to the preceding sentence, this Agreement shall be binding upon, inure to the
benefit of and be enforceable by the parties and their respective successors and
assigns.
 
     (i) Further Assurances.  In the event of any exercise of the Option by the
Holder, Issuer, and the Holder shall execute and deliver all other documents and
instruments and take all other action that may be reasonably necessary in order
to consummate the transactions provided for by such exercise.
 
     (j) Specific Performance.  The parties hereto agree that this Agreement may
be enforced by either party through specific performance, injunctive relief and
other equitable relief. Both parties further agree to waive any requirement for
the securing or posting of any bond in connection with the obtaining of any such
equitable relief and that this provision is without prejudice to any other
rights that the parties hereto may have for any failure to perform this
Agreement.

the related preferred share purchase right issued pursuant to the rights
agreement between the AFC and ChaseMellon Shareholder Services, L.L.C. dated as
of July 17, 1996 (collectively, the "Merger Consideration").
 
     (i) The Cash Consideration shall be $19.00 for each share of GNYSB Common
Stock.
 
     (ii) The Stock Consideration shall be 0.50 of a share of AFC Common Stock
for each share of GNYSB Common Stock.
 
     (iii) If between the date of the Agreement and the Effective Time the
outstanding shares of AFC Common Stock shall have been changed into a different
number of shares or into a different class, by reason of any stock dividend,
subdivision, reclassification, recapitalization, split, combination or exchange
of shares (each, a "Stock Adjustment"), the Merger Consideration shall be
adjusted correspondingly to the extent appropriate to reflect the Stock
Adjustment.
 
     (iv) As used herein, "AFC Market Value" shall be the average of the mean
between the closing high bid and low asked prices of a share of AFC Common

of expiration of the last waiting period with respect to any of the required
regulatory approvals, as defined in Section 5.01(b) of the Agreement, (ii) the
day on which the last of the required regulatory approvals, as defined in
Section 5.01(b) of the Agreement, is obtained and (iii) the day on which the
last of the required stockholder approvals have been received.
 
     (b) As of the Effective Time, each Excluded Share, other than Dissenters'
Shares, shall be cancelled and retired and cease to exist, and no exchange or
payment shall be made with respect thereto.
 
     (c) As of the Effective Time, all shares of GNYSB Common Stock other than
Excluded Shares shall no longer be outstanding and shall be automatically

formerly representing any such shares of GNYSB Common Stock shall cease to have
any rights with respect thereto, except the right to receive the Merger
Consideration. After the Effective Time, there shall be no transfers on the
stock transfer books of AFC.
 
     4.3 Preferred Stock of GNYSB.  At or immediately prior to the Effective
Time, the Certificate of Incorporation of AFC shall be amended to (i) change the

share to $1.00 per share and (ii) fix the preferences of a newly-created Series
B Preferred Stock of AFC (the "AFC Series B Preferred Stock") to have terms
substantially identical, and in any event no less favorable, to those of the 12%
Noncumulative Preferred Stock, Series B of GNYSB (the "GNYSB Series B Preferred
Stock") and agreeable to GNYSB; provided, that, AFC may, in its sole discretion,
effect such an amendment provided for in clause (ii) above through a Certificate
of Designations filed pursuant to Section 151 of the Delaware General
Corporation Law. At the Effective Time, each share of the GNYSB Series B
Preferred Stock issued and outstanding immediately prior to the Effective Time
shall, by virtue of the Merger and without any action on the part of the holder
thereof, be converted into, and shall become, one share of the AFC Series B
Preferred Stock, as provided in Article I of the Agreement.
 
     4.4 Fractional Shares.  Notwithstanding any other provision hereof, no
fraction of a whole share of the AFC Common Stock and no certificates or scrip
therefor will be issued in the Merger; instead, the AFC shall pay to each holder
of the GNYSB Common Stock who would otherwise be entitled to a fractional share
an amount in cash, rounded to the nearest cent, determined by multiplying such
fraction by the AFC Market Value.

Board of Directors
The Greater New York Savings Bank
One Penn Plaza
New York, New York 10119
 
Ladies and Gentlemen:
 
     The Greater New York Savings Bank ("GNYSB"), Astoria Financial Corporation
("Astoria") and Astoria Federal Savings and Loan Association, a wholly-owned
subsidiary of Astoria (the "Association"), have entered into an Agreement and
Plan of Merger, dated as of March 29, 1997 (the "Agreement"), pursuant to which
GNYSB will be merged with and into the Association (the "Merger"). Upon
consummation of the Merger, each outstanding share of GNYSB common stock, par
value $1.00 per share (including any shares that are issued upon the conversion
of shares of GNYSB Series A 8.25% ESOP Cumulative Convertible Preferred Stock,
par value $1.00 per share, the "GNYSB Shares"), other than certain GNYSB Shares
specified in the Agreement, will be converted into the right to receive, at the
election of the holder thereof, either .50 of a share of common stock, par value
$.01 per share, of Astoria (the "Astoria Shares") or $19.00 in cash, subject in
each case to proration so that 75% of the entire consideration payable by
Astoria will be common stock and 25% will be cash. In addition, each share of
GNYSB 12% Noncumulative Perpetual Preferred Stock, Series B, par value $1.00 per
share (the "Series B Preferred"), will be converted into one share of a newly
created series of preferred stock of Astoria (the "Astoria Preferred") having
substantially identical, and in any event no less favorable, terms and
conditions as the Series B Preferred (the "Preferred Exchange"). The terms and
conditions of the Merger are more fully set forth in the Agreement. You have
requested our opinion as to the fairness, from a financial point of view, of the
consideration to be received by the holders of the GNYSB Shares and the Series B
Preferred.
 
     Sandler O'Neill & Partners, L.P., as part of its investment banking
business, is regularly engaged in the valuation of financial institutions and
their securities in connection with mergers and acquisitions and other corporate
transactions. In connection with this opinion, we have reviewed, among other
things: (i) the Agreement and exhibits thereto; (ii) the Stock Option Agreement,
dated as of March 29, 1997, by and between Astoria and GNYSB; (iii) the Joint
Proxy Statement-Prospectus of GNYSB and Astoria dated as of the date hereof;
(iv) Astoria's audited consolidated financial statements and management's
discussion and analysis of the financial condition and results of operations as
contained in its annual report to shareholders for the year ended December 31,
1996; (v) GNYSB's audited consolidated financial statements and management's
discussion and analysis of the financial condition and results of operations as
contained in its annual report to shareholders for the year ended December 31,
1996; (vi) the Proxy Statement of GNYSB dated March 14, 1997; (vii) Astoria's
unaudited consolidated financial statements and management's discussion and
analysis of the financial condition and results of operations contained in its
Quarterly Report on Form 10-Q for the quarter ended March 31, 1997; (viii)
GNYSB's unaudited consolidated financial statements and management's discussion
and analysis of the financial condition and results of operations contained in
its Quarterly Report on Form 10-Q for the quarter ended March 31, 1997; (ix)
certain financial analyses and forecasts of GNYSB prepared by and reviewed with
management of GNYSB and the views of senior management of GNYSB regarding
GNYSB's past and current business operations, results thereof, financial
condition and future prospects; (x) certain financial analyses and forecasts of
Astoria prepared by and reviewed with management of Astoria and the views of
senior management of Astoria regarding Astoria's past and current business
operations, results thereof, financial condition and future prospects; (xi) the
pro forma impact of the Merger on Astoria, including discussions with senior
management of Astoria regarding their dividend philosophy and policy with
respect to the Astoria Shares and the Astoria Preferred; (xii) the historical
reported price and trading activity for Astoria's and GNYSB's common stock,
including a
 
                                       D-1
<PAGE>   185
 
comparison of certain financial and stock market information for Astoria and
GNYSB with similar information for certain other companies the securities of
which are publicly traded; (xiii) the financial terms of recent business
combinations in the savings institution and banking industries; (xiv) the
current market environment generally and the banking environment in particular;
and (xv) such other information, financial studies, analyses and investigations
and financial, economic and market criteria as we considered relevant. We were
not asked to, and did not, solicit indications of interest in a potential
transaction from other third parties other than one third party specifically
identified to us by GNYSB's Board of Directors.
 
     In performing our review, we have assumed and relied upon, without
independent verification, the accuracy and completeness of all the financial
information, analyses and other information reviewed by and discussed with us,
and we did not make an independent evaluation or appraisal of the specific
assets, the collateral securing assets or the liabilities of Astoria or GNYSB or
any of their subsidiaries, or the collectibility of any such assets (relying,
where relevant, on the analyses and estimates of Astoria and GNYSB). With
respect to the financial projections reviewed with management, we have assumed
that they have been reasonably prepared on bases reflecting the best currently
available estimates and judgments of the respective managements of the
respective future financial performances of Astoria and GNYSB and that such
performances will be achieved. We have also assumed that there has been no
material change in Astoria's or GNYSB's assets, financial condition, results of
operations, business or prospects since March 31, 1997, the date of the last
financial statements noted above. We have assumed that Astoria will remain as a
going concern for all periods relevant to our analyses and that the conditions
precedent in the Agreement are not waived. With respect to the Preferred
Exchange, we have also assumed that the terms and conditions of the Astoria
Preferred are substantially identical to the Series B Preferred and that there
are no material and adverse differences in the rights and privileges of the
holders of the Astoria Preferred under Delaware law as compared to the rights
and privileges of holders of the Series B Preferred under New York law.
 
     Our opinion is necessarily based on economic, market and other conditions
as in effect on, and the information made available to us as of, the date
hereof. Events occurring after the date hereof could materially affect the
assumptions used in preparing this opinion. We have not undertaken to reaffirm
or revise this opinion or otherwise comment upon events occurring after the date
hereof.
 
     We have acted as GNYSB's financial advisor in connection with the Merger
and will receive a fee for our services, a significant portion of which is
contingent upon consummation of the Merger. We have also received a fee for
rendering this opinion. We have also provided and continue to provide general
financial advisory services for GNYSB and have received and will continue to
receive fees for such services.
 
     In the ordinary course of our business, we may actively trade the equity
securities of Astoria and GNYSB for our own account and for the accounts of our
customers and, accordingly, may at any time hold a long or short position in
such securities.
 
     Our opinion is directed to the Board of Directors of GNYSB and does not
constitute a recommendation to any stockholder of GNYSB as to how such
stockholder should vote at the special meeting of stockholders called to
consider and vote upon the Merger. Our opinion is not to be quoted or referred
to, in whole or in part, in a registration statement, prospectus, proxy
statement or in any other document, nor shall this opinion be used for any other
purposes, without Sandler O'Neill's prior written consent; provided, however,
that we hereby consent to the inclusion of this opinion as an exhibit to the
Joint Proxy Statement-Prospectus of GNYSB and Astoria dated the date hereof.
 
     Based upon and subject to the foregoing, it is our opinion that the
consideration to be received by the holders of the GNYSB Shares and the Series B
Preferred is fair, from a financial point of view, to the holders of such
shares.
 
                                          Very truly yours,
 
                                      /s/ Sandler O'Neill & Partners, L.P.

Board of Directors
Astoria Financial Corporation
One Astoria Federal Plaza
Lake Success, NY 11042-1085
 
Members of the Board:
 
     We understand that Astoria Financial Corporation (along with its
subsidiaries, "Astoria"), Astoria Federal Savings and Loan Association, a wholly
owned subsidiary of Astoria (along with its subsidiaries, "Astoria Federal") and
The Greater New York Savings Bank (along with its subsidiaries, "Greater") have
entered into an Agreement and Plan of Merger, dated as of March 29, 1997 (the
"Agreement"), pursuant to which Greater will be merged with and into Astoria
Federal in a transaction (the "Merger") in which each outstanding share of
Greater common stock, par value $1.00 per share (the "Greater Shares"), will be
converted into the right to receive, at the option of the holder of such share
(subject to certain proration limitations set forth below) either (i) 0.50 of a
share of the common stock, par value $0.01 per share, of Astoria (the "Astoria
Shares") or (ii) $19.00 in cash (such fraction of an Astoria Share or such
amount of cash being referred to herein as the "Merger Consideration"); that
proration limitations will apply to any stockholder's election to choose Astoria
Shares or cash such that the number of Greater Shares to be converted into
Astoria Shares in the Merger shall be equal to 75% of the number of Greater
Shares outstanding on the effective date of the Merger; and that each
outstanding share of Greater Series A ESOP Convertible Preferred Stock will be
redeemed prior to the Merger (subject to the rights of the holders thereof to
convert into Greater Shares) and each outstanding share of Greater 12%
Noncumulative Preferred Stock, Series B (the "Greater Series B Preferred") will
become and be converted into one share of a new series of preferred stock of
Astoria having terms substantially identical to those of the Greater Series B
Preferred, all as set forth more fully in the Agreement.
 
     You have asked us whether, in our opinion, the proposed Merger
Consideration is fair to Astoria from a financial point of view.
 
     In arriving at the opinion set forth below, we have, among other things:
 
     (1) reviewed certain publicly available business and financial information
         relating to Astoria and Greater which we deemed to be relevant;
 
     (2) reviewed certain information, including financial forecasts, relating
         to the business, earnings, cash flow, assets, liabilities and prospects
         of Astoria and Greater, as well as the amount and timing of the cost
         savings and related expenses and revenue enhancements expected to
         result from the Merger (the "Expected Synergies"), furnished to us by
         senior management of Astoria and Greater;
 
     (3) conducted discussions with members of senior management of Astoria and
         Greater concerning the foregoing, including the respective businesses,
         prospects, regulatory condition and contingencies of Astoria and
         Greater, before and after giving effect to the Merger, and the Expected
         Synergies;
 
     (4) reviewed the market prices and valuation multiples for the Astoria
         Shares and the Greater Shares and compared them with those of certain
         publicly traded companies which we deemed to be relevant;
 
     (5) reviewed the results of operations of Astoria and Greater and compared
         them with those of certain publicly traded companies which we deemed to
         be relevant;
 
     (6) reviewed the proposed financial terms of the Merger with the financial
         terms of certain other transactions which we deemed to be relevant;

     (7) reviewed the pro forma impact of the Merger;
 
     (8) reviewed the Agreement and Plan of Merger; and
 
     (9) reviewed such other financial studies and analyses and took into
         account such other matters as we deemed necessary, including our
         assessment of general economic, market and monetary conditions.
 
     In preparing our opinion we have assumed and relied on the accuracy and
completeness of all information supplied or otherwise made available to us,
discussed with or reviewed by or for us, or publicly available, and we have not
assumed responsibility for independently verifying such information or
undertaken an independent evaluation or appraisal of any of the assets or
liabilities, contingent or otherwise, of Astoria or Greater or any of their
subsidiaries, nor have we been furnished with any such evaluation or appraisal.
We are not experts in the evaluation of allowances for loan losses and we have
not made an independent evaluation of the adequacy of the allowance for loan
losses of Astoria or Greater, nor have we reviewed any individual credit files
relating to Greater or Astoria and we have assumed that the aggregate allowance
for loan losses for each of Greater and Astoria is adequate to cover such losses
and will be adequate on a pro forma basis for the combined entity, utilizing
Astoria's ordinary course practice for such allowances. In addition, we have not
conducted any physical inspection of the properties or facilities of Astoria or
Greater. With respect to the financial forecast information, including, without
limitation, financial forecasts, evaluations of contingencies and projections
regarding under-performing and non-performing assets, net charge-offs, adequacy
of reserves and future economic conditions, and the Expected Synergies,
furnished to or discussed with us by Astoria or Greater, we have assumed that
they have been reasonably prepared and reflect the best currently available
estimates, allocations and judgment of Astoria's or Greater's management as to
the expected future financial performance of Astoria or Greater, as the case may
be, and the Expected Synergies. We express no opinion as to such financial
forecast information or the Expected Synergies or the assumptions on which they
were based. We have further assumed that the Merger will be accounted for as a
purchase under generally accepted accounting principles and that it will qualify
as a tax-free reorganization for United States federal income tax purposes.
 
     Our opinion is necessarily based upon market, economic and other conditions
as in effect on, and the information made available to us as of, the date
hereof. For purposes of rendering this opinion we have assumed, in all respects
material to our analysis, that the representations and warranties of each party
in the Agreement and all related documents and instruments (collectively, the
"Documents") contained therein are true and correct, that each party to the
Documents will perform all of the covenants and agreements required to be
performed by such party under such Documents, and that all conditions to the
consummation of the Merger will be satisfied without waiver thereof. We have
also assumed that in the course of obtaining the necessary regulatory or other
consents or approvals (contractual or otherwise) for the Merger, no
restrictions, including any divestiture requirements or amendments or
modifications, will be imposed that will have a material adverse effect on the
contemplated benefits of the Merger.
 
     We are acting as financial advisor to Astoria in connection with the Merger
and will receive a fee from Astoria for our services, a significant portion of
which is contingent upon the consummation of the Merger. In addition, Astoria
has agreed to indemnify us for certain liabilities arising out of our
engagement. We have, in the past, provided financial advisory and/or financing
services to Astoria and Greater and may continue to do so and have received, and
may receive, fees for the rendering of such services. In addition, in the
ordinary course of our business, we may actively trade debt and/or equity
securities of Astoria and Greater and their respective affiliates for our own
account and for the accounts of customers and, accordingly, may at any time hold
a long or short position in such securities.
 
     This opinion is for the use and benefit of the Board of Directors of
Astoria. Our opinion does not address the merits of the underlying decision by
Astoria to engage in the Merger, and does not constitute a recommendation to any
shareholder as to how such shareholder should vote on or with respect to the
proposed Merger.

     We are not expressing any opinion herein as to the prices at which the
Astoria Shares will trade following the announcement or consummation of the
Merger.
 
     On the basis of and subject to the foregoing, we are of the opinion that,
as of the date hereof, the Merger Consideration is fair from a financial point
of view to Astoria.
 
                                          Very truly yours,

SEC.6022. PROCEDURE TO ENFORCE STOCKHOLDER'S RIGHT TO RECEIVE PAYMENT FOR SHARES
 
     1. A stockholder intending to enforce his right under a section of this
chapter to receive payment for his shares if the proposed corporate action
referred to therein is taken shall file with the corporation, before the meeting
of stockholders at which the action is submitted to a vote, or at such meeting
but before the vote, written objection to the action. The objection shall
include a statement that he intends to demand payment for his shares if the
action is taken. Such objection is not required from any stockholder to whom the
corporation did not give notice of such meeting in accordance with this chapter
or where the proposed action is authorized by written consent of stockholders
without a meeting.
 
     2. Within ten days after the stockholders' authorization date, which term
as used in this section means the date on which the stockholders' vote
authorizing such action was taken, or the date on which such consent without a
meeting was obtained from the requisite stockholders, the corporation shall give
written notice of such authorization or consent by registered mail to each
stockholder who filed written objection or from whom written objection was not
required, excepting any who voted for or consented in writing to the proposed
action.
 
     3. Within twenty days after the giving of notice to him, any stockholder to
whom the corporation was required to give such notice and who elects to dissent
shall file with the corporation a written notice of such election, stating his
name and residence address, the number and classes of shares as to which he
dissents and a demand for payment of the fair value of his shares.
 
     4. A stockholder may not dissent as to less than all of the shares, held by
him of record, that he owns beneficially. A nominee or fiduciary may not dissent
on behalf of any beneficial owner as to less than all of the shares of such
owner held of record by such nominee or fiduciary.
 
     5. Upon filing a notice of election to dissent, the stockholder shall cease
to have any of the rights of a stockholder except the right to be paid the fair
value of his shares and any other rights under this section. Withdrawal of a
notice of election shall require the written consent of the corporation. If a
notice of election is withdrawn, or the proposed corporate action is abandoned
or rescinded, or a court shall determine that the stockholder is not entitled to
receive payment for his shares, or the stockholder shall otherwise lose his
dissenter's rights, he shall not have the right to receive payment for his
shares and he shall be reinstated to all his rights as a stockholder as of the
filing of his notice of election, including any intervening preemptive rights
and the right to payment of any intervening dividend or other distribution or,
if any such rights have expired or any such dividend or distribution other than
in cash has been completed, in lieu thereof, at the election of the corporation,
the fair value thereof in cash as determined by the board as of the time of such
expiration or completion, but without prejudice otherwise to any corporate
proceedings that may have been taken in the interim.
 
     6. At the time of filing the notice of election to dissent or within one
month thereafter the stockholder shall submit the certificates representing his
shares to the corporation, or to its transfer agent, which shall forthwith note
conspicuously thereon that a notice of election has been filed and shall return
the certificates to the stockholder or other person who submitted them on his
behalf. Any stockholder who fails to submit his certificates for such notation
as herein specified shall, at the option of the corporation exercised by written
notice to him within forty-five days from the date of filing of such notice of
election to dissent, lose his dissenter's rights unless a court, for good cause
shown, shall otherwise direct. Upon transfer of a certificate bearing such
notation, each new certificate issued therefor shall bear a similar notation
together with the name of the original dissenting holder of the shares and a
transferee shall acquire no rights in the corporation except those which the
original dissenting stockholder had after filing his notice of election.
 
     7. Within seven days after the expiration of the period within which
stockholders may file their notices of election to dissent, or within seven days
after the proposed corporate action is consummated, whichever is later, the
corporation or, in the case of a merger, the receiving corporation, shall make a
written offer by registered mail to each stockholder who has filed such notice
of election to pay for his shares at a specified price which the corporation
considers to be their fair value. Such offer shall be made at the same price per
share to all dissenting stockholders of the same class, or if divided into
series, of the same series and shall be
 
                                       F-1
<PAGE>   190
 
accompanied by a balance sheet of the corporation whose shares the dissenting
stockholder holds as of the latest available date, which shall not be earlier
than twelve months before the making of such offer, and a profit and loss
statement or statements for not less than a twelve month period ended on the
date of such balance sheet or, if the corporation was not in existence
throughout such twelve month period, for the portion thereof during which it was
in existence. If within thirty days after the making of such offer, the
corporation making the offer and any stockholder agree upon the price to be paid
for his shares, payment therefor shall be made within sixty days after the
making of such offer upon the surrender of the certificates representing such
shares.
 
     8. The following procedure shall apply if the corporation fails to make
such offer within such period of seven days, or if it makes the offer and any
dissenting stockholder or stockholders fail to agree with it within the period
of thirty days thereafter upon the price to be paid for their shares:
 
          (a) The corporation or, in the case of a merger, the receiving
     corporation shall, within twenty days after the expiration of whichever is
     applicable of the two periods last mentioned, institute a special
     proceeding in the supreme court in the judicial district in which the
     office of the corporation is located to determine the rights of dissenting
     stockholders and to fix the fair value of their shares.
 
          (b) If the corporation fails to institute such proceeding within such
     period of twenty days, any dissenting stockholder may institute such
     proceeding for the same purpose not later than thirty days after the
     expiration of such twenty day period. If such proceeding is not instituted
     within such thirty day period, all dissenter's rights shall be lost unless
     the supreme court, for good cause shown, shall otherwise direct.
 
          (c) All dissenting stockholders, excepting those who, as provided in
     subdivision seven, have agreed with the corporation upon the price to be
     paid for their shares, shall be made parties to such proceeding, which
     shall have the effect of an action quasi in rem against their shares. The
     corporation shall serve a copy of the petition in such proceeding upon each
     dissenting stockholder who is a resident of this state in the manner
     provided by law for the service of a summons, and upon each nonresident
     dissenting stockholder either by registered mail and publication, or in
     such other manner as is permitted by law. The jurisdiction of the court
     shall be plenary and exclusive.
 
          (d) The court shall determine whether each dissenting stockholder, as
     to whom the corporation requests the court to make such determination, is
     entitled to receive payment for his shares. If the corporation does not
     request any such determination or if the court finds that any dissenting
     stockholder is so entitled, it shall proceed to fix the value of the
     shares, which, for the purposes of this section, shall be the fair value as
     of the close of business on the day prior to the stockholders'
     authorization date, excluding any appreciation or depreciation directly or
     indirectly induced by such corporate action or its proposal. The court may,
     if it so elects, appoint an appraiser to receive evidence and recommend a
     decision on the question of fair value. Such appraiser shall have the
     power, authority and duties specified in the order appointing him, or any
     amendment thereof.
 
          (e) The final order in the proceeding shall be entered against the
     corporation in favor of each dissenting stockholder who is a party to the
     proceeding and is entitled thereto for the value of his shares so
     determined.
 
          (f) The final order shall include an allowance for interest at such
     rate as the court finds to be equitable, from the stockholders'
     authorization date to the date of payment. If the court finds that the
     refusal of any stockholder to accept the corporate offer of payment for his
     shares was arbitrary, vexatious or otherwise not in good faith, no interest
     shall be allowed to him.
 
          (g) The costs and expenses of such proceeding shall be determined by
     the court and shall be assessed against the corporation, or, in the case of
     a merger, the receiving corporation, except that all or any part of such
     costs and expenses may be apportioned and assessed, as the court may
     determine, against any or all of the dissenting stockholders who are
     parties to the proceeding if the court finds that their refusal to accept
     the corporate offer was arbitrary, vexatious or otherwise not in good
     faith. Such expenses shall include reasonable compensation for and the
     reasonable expenses of the appraiser, but shall exclude
 
                                       F-2
<PAGE>   191
 
     the fees and expenses of counsel for and experts employed by any party
     unless the court, in its discretion, awards such fees and expenses. In
     exercising such discretion, the court shall consider any of the following:
     (A) that the fair value of the shares as determined materially exceeds the
     amount which such corporation offered to pay; (B) that no offer was made by
     such corporation; and (C) that such corporation failed to institute the
     special proceeding within the period specified therefor.
 
          (h) Within sixty days after final determination of the proceeding, the
     corporation or, in the case of a merger, the receiving corporation shall
     pay to each dissenting stockholder the amount found to be due him, upon
     surrender of the certificates representing his shares.
 
     9. Shares acquired by the corporation upon the payment of the agreed value
therefor or of the amount due under the final order, as provided in this
section, shall be dealt with as provided in section five thousand fourteen,
except that, in the case of a merger, they shall be disposed of as provided in
the plan of merger or consolidation.
 
     10. The enforcement by a stockholder of his right to receive payment for
his shares in the manner provided herein shall exclude the enforcement by such
stockholder of any other right to which he might otherwise be entitled by virtue
of share ownership, except as provided in subdivision five, and except that this
section shall not exclude the right of such stockholder to bring or maintain an
appropriate action to obtain relief on the ground that such corporate action
will be or is illegal or fraudulent as to him.
 
     11. Except as otherwise expressly provided in this section, any notice to
be given by a corporation to a stockholder under this section shall be given in
the manner provided in section six thousand five.

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Section 145 of the Delaware General Corporation Law ("Delaware General
Corporation Law"), inter alia, empowers a Delaware corporation to indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding (other than an
action by or in the right of the corporation) by reason of the fact that such
person is or was a director, officer, employee or agent of another corporation
or other enterprise, against expenses (including attorneys' fees), judgments,
fines and amounts paid in settlement actually and reasonably incurred by him in
connection with such action, suit or proceeding if he acted in good faith and in
a manner he reasonably believed to be in or not opposed to the best interest of
the corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. Similar indemnity is
authorized for such person against expenses (including attorneys' fees) actually
and reasonably incurred in connection with the defense or settlement of any such
threatened, pending or completed action or suit if such person acted in good
faith and in a manner he reasonably believed to be in or not opposed to the best
interests of the corporation, and provided further that (unless a court of
competent jurisdiction otherwise provides) such person shall not have been
adjudged liable to the corporation. Any such indemnification may be made only as
authorized in each specific case upon a determination by the shareholders or
disinterested directors or by independent legal counsel in a written opinion
that indemnification is proper because the indemnitee has met the applicable
standard of conduct.
 
     Section 145 further authorizes a corporation to purchase and maintain
insurance on behalf of any person who is or was a director, officer, employee or
agent of the corporation, or is or was serving at the request of the corporation
as a director, officer, employee or agent of another corporation or enterprise,
against any liability asserted against him, and incurred by him in any such
capacity, or arising out of his status as such, whether or not the corporation
would otherwise have the power to indemnify him under Section 145.
 
     The Registrant has also entered into employment agreements with certain
executive officers, which agreements require that the Registrant maintain a
directors' and officers' liability policy for the benefit of such officers and
that the Registrant will indemnify such officers to the fullest extent permitted
by law.
 
     In addition, pursuant to the Merger Agreement, the Registrant has agreed
for a period of six years following the effective time of the Merger to
indemnify certain employees, directors and officers The Greater New York Savings
Bank with respect to acts or omissions occurring prior to the effective time of
the Merger. The Registrant has also agreed in the Merger Agreement to maintain
for a period of six years following the effective time of the Merger the
directors' and officers' liability insurance coverage maintained by The Greater
New York Savings Bank (or substantially equivalent coverage under substitute
policies) with respect to any claims arising out of any actions or omissions
occurring prior to the effective time of the Merger.
 
     In accordance with the General Corporation Law of the State of Delaware
(being Chapter 1 of Title 8 of the Delaware Code), Articles 10 and 11 of the
Registrant's Certificate of Incorporation provide as follows:
 
TENTH:
 
A.  Each person who was or is made a party or is threatened to be made a party
to or is otherwise involved in any action, suit or proceeding, whether civil,
criminal, administrative or investigative (hereinafter a "proceeding"), by
reason of the fact that he or she is or was a Director or an Officer of the
Corporation or is or was serving at the request of the Corporation as a
Director, Officer, employee or agent of another corporation of or a partnership,
joint venture, trust or other enterprise, including service with respect to an
employee benefit plan (hereinafter an "indemnitee"), whether the basis of such
proceeding is alleged action in an official capacity as a Director, Officer,
employee or agent or in any other capacity while serving as a Director, Officer,
employee or agent, shall be indemnified and held harmless by the Corporation to
the fullest extent authorized by the Delaware General Corporation Law, as the
same exists or may hereafter be amended (but, in the case of any such amendment,
only to the extent that such amendment permits the Corporation to provide
broader
 
                                      II-1
<PAGE>   193
 
indemnification rights than such law permitted the Corporation to provide prior
to such amendment), against all expense, liability and loss (including
attorneys' fees, judgments, fines, ERISA excise taxes or penalties and amounts
paid in settlement) reasonably incurred or suffered by such indemnitee in
connection therewith; provided, however, that, except as provided in Section C
hereof with respect to proceedings to enforce rights to indemnification, the
Corporation shall indemnify any such indemnitee in connection with a proceeding
(or part thereof) initiated by such indemnitee only if such proceeding (or part
thereof) was authorized by the Board of Directors of the Corporation.
 
B.  The right to indemnification conferred in Section A of this Article TENTH
shall include the right to be paid by the Corporation the expenses incurred in
defending any such proceeding in advance of its final disposition (hereinafter
an "advancement of expenses"); provided, however, that, if the Delaware General
Corporation Law requires, an advancement of expenses incurred by an indemnitee
in his or her capacity as a Director or Officer (and not in any other capacity
in which service was or is rendered by such indemnitee, including, without
limitation, services to an employee benefit plan) shall be made only upon
delivery to the Corporation of an undertaking (hereinafter an "undertaking"), by
or on behalf of such indemnitee, to repay all amounts so advanced if it shall
ultimately be determined by final judicial decision from which there is no
further right to appeal (hereinafter a "final adjudication") that such
indemnitee is not entitled to be indemnified for such expenses under this
Section or otherwise. The rights to indemnification and to the advancement of
expenses conferred in Sections A and B of this Article TENTH shall be contract
rights and such rights shall continue as to an indemnitee who has ceased to be a
Director, Officer, employee or agent and shall inure to the benefit of the
indemnitee's heirs, executors and administrators.
 
C.  If a claim under Section A or B of this Article TENTH is not paid in full by
the Corporation within sixty days after a written claim has been received by the
Corporation, except in the case of a claim for an advancement of expenses, in
which case the applicable period shall be twenty days, the indemnitee may at any
time thereafter bring suit against the Corporation to recover the unpaid amount
of the claim. If successful in whole or in part in any such suit, or in a suit
brought by the Corporation to recover an advancement of expenses pursuant to the
terms of an undertaking, the indemnitee shall be entitled to be paid also the
expenses of prosecuting or defending such suit. In (i) any suit brought by the
indemnitee to enforce a right to indemnification hereunder (but not in a suit
brought by the indemnitee to enforce a right to an advancement of expenses) it
shall be a defense that, and (ii) in any suit by the Corporation to recover an
advancement of expenses pursuant to the terms of an undertaking the Corporation
shall be entitled to recover such expenses upon a final adjudication that, the
indemnitee has not met any applicable standard for indemnification set forth in
the Delaware General Corporation Law. Neither the failure of the Corporation
(including its Board of Directors, independent legal counsel, or its
stockholders) to have made a determination prior to the commencement of such
suit that indemnification of the indemnitee is proper in the circumstances
because the indemnitee has met the applicable standard of conduct set forth in
the Delaware General Corporation Law, nor an actual determination by the
Corporation (including its Board of Directors, independent legal counsel, or its
stockholders) that the indemnitee has not met such applicable standard of
conduct, shall create a presumption that the indemnitee has not met the
applicable standard of conduct or, in the case of such a suit brought by the
indemnitee, be a defense to such suit. In any suit brought by the indemnitee to
enforce a right to indemnification or to an advancement of expenses hereunder,
or by the Corporation to recover an advancement of expenses pursuant to the
terms of an undertaking, the burden of proving that the indemnitee is not
entitled to be indemnified, or to such advancement of expenses under this
Article TENTH or otherwise shall be on the Corporation.
 
D.  The rights to indemnification and to the advancement of expenses conferred
in this Article TENTH shall not be exclusive of any other right which any person
may have or hereafter acquire under any statute, the Corporation's Certificate
of Incorporation, Bylaws, agreement, vote of stockholders or Disinterested
Directors or otherwise.
 
E.  The Corporation may maintain insurance, at its expense, to protect itself
and any Director, Officer, employee or agent of the Corporation or another
corporation, partnership, joint venture, trust or other enterprise against any
expense, liability or loss, whether or not the Corporation would have the power
to indemnify such person against such expense, liability or loss under the
Delaware General Corporation Law.
 
                                      II-2
<PAGE>   194
 
F.  The Corporation may, to the extent authorized from time to time by the Board
of Directors, grant rights to indemnification and to the advancement of expenses
to any employee or agent of the Corporation to the fullest extent of the
provisions of this Article TENTH with respect to the indemnification and
advancement of expenses of Directors and Officers of the Corporation.
 
ELEVENTH:
 
     A Director of this Corporation shall not be personally liable to the
Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a Director, except for liability (i) for any breach of the Director's
duty of loyalty to the Corporation or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) under Section 174 of the Delaware General Corporation
Law, or (iv) for any transaction from which the Director derived an improper
personal benefit. If the Delaware General Corporation Law is amended to
authorize corporate action further eliminating or limiting the personal
liability of Directors, then the liability of a Director of the Corporation
shall be eliminated or limited to the fullest extent permitted by the Delaware
General Corporation Law, as so amended.
 
     Any repeal or modification of the foregoing paragraph by the stockholders
of the Corporation shall not adversely affect any right or protection of a
Director of the Corporation existing at the time of such repeal or modification.

ITEM 22.  UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes:
 
          (a)(1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this Registration Statement:
 
             (i) To include any Prospectus required by Section 10(a)(3) of the
        Securities Act of 1933;
 
             (ii) To reflect in the Prospectus any facts or events arising after
        the effective date of the Registration Statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the Registration Statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) if, in the aggregate, the
        changes in volume and price represent no more than a 20% change in the
        maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective Registration Statement; and To
        include any material information with respect to the plan of
        distribution not previously disclosed in the Registration Statement or
        any material change to such information in the Registration Statement.
 
          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.
 
          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.
 
          (b) For purposes of determining any liability under the Securities Act
     of 1933, each filing of the Registrant's annual report pursuant to Section
     13(a) or 15(d) of the Securities Exchange Act of 1934 (and each filing of
     an employee benefit plan's annual report pursuant to Section 15(d) of the
     Securities Exchange Act of 1934) that is incorporated by reference in the
     Registration Statement shall be deemed a new registration statement
     relating to the securities offered therein, and the offering of such
     securities at that time shall be deemed to be the initial bona fide
     offering thereof.
 
          (c)(1) That prior to any public reoffering of the securities
     registered hereunder through use of a prospectus which is a part of this
     registration statement, by any person or party who is deemed to be an
     underwriter within the meaning of Rule 145(c), the issuer undertakes that
     such reoffering prospectus will contain the information called for by the
     applicable registration form with respect to reofferings by persons who may
     be deemed underwriters, in addition to the information called for by the
     other items of the applicable form.
 
          (2) That every prospectus: (i) that is filed pursuant to paragraph
     (c)(1) immediately preceding, or (ii) that purports to meet the
     requirements of Section 10(a)(3) of the Act and is used in connection with
     an offering of securities subject to Rule 415, will be filed as a part of
     an amendment to the registration statement and will not be used until such
     amendment is effective, and that, for purposes of determining any liability
     under the Securities Act of 1933, each such post-effective amendment shall
     be deemed to be
 
                                      II-6
<PAGE>   198
 
     a new registration statement relating to the securities offered therein,
     and the offering of such securities at that time shall be deemed to be the
     initial bona fide offering thereof.
 
          (d) To respond to requests for information that is incorporated by
     reference into the Joint Proxy Statement-Prospectus pursuant to Item 4,
     10(b), 11, or 13 of this form, within one business day of receipt of such
     request, and to send the incorporated documents by first class mail or
     other equally prompt means. This includes information contained in
     documents filed subsequent to the effective date of the registration
     statement through the date of responding to the request.
 
          (e) To supply by means of a post-effective amendment all information
     concerning a transaction, and the company being acquired involved therein,
     that was not the subject of and included in the registration statement when
     it became effective.
 
     Insofar as indemnification by the Registrant for liabilities arising under
the Securities Act of 1933 may be permitted to directors, officers and
controlling persons of the Registrant pursuant to the foregoing provisions, or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

Ladies and Gentlemen:

        We have acted as special counsel for Astoria Financial Corporation, a
Delaware corporation ("AFC"), and Astoria Federal Savings and Loan Association,
a federally chartered stock form savings and loan association and wholly-owned
subsidiary of AFC ("AFSL"), in connection with the issuance of and registration
under the Securities Act of 1933, as amended, by AFC of an aggregate of
5,666,517 shares, subject to adjustment, of AFC common stock, par value $0.01
per share (the "Merger Shares"), into which certain shares of common stock, par
value $1.00 per share, of The Greater New York Savings Bank, a New York State
chartered stock form savings bank ("GNYSB"), will be converted pursuant to an
Agreement and Plan of Merger, dated as of the 29th day of March, 1997, by and
among AFC, AFSL, and GNYSB, as amended (the "Merger Agreement"), and the related
preparation and filing by AFC with the Securities and Exchange Commission of a
registration statement on Form S-4 (the "Registration Statement"). In rendering
the opinions set forth below, we do not express any opinion concerning law other
than the federal law of the United States and the corporate law of the State of
Delaware.

        We have examined originals or copies, certified or otherwise identified
to our satisfaction, of such documents, corporate records and other
instruments, and have examined such matters of law, as we have deemed necessary
or advisable for purposes of rendering the opinions set forth below. As to
matters of fact, we have examined and relied upon the representations of AFC,
AFSL and GNYSB contained in the Merger Agreement and the Registration Statement
and, where we have deemed appropriate, representations or certificates of
officers of AFC, AFSL or GNYSB or public officials. We have assumed the
authenticity of all documents submitted to us as originals, the genuineness of
all signatures, the legal capacity of natural persons and the conformity to the
originals of all documents submitted to us as copies. In making our examination
of any documents, we have assumed that all parties, other than AFC and the AFSL,
had the corporate power and authority to enter into and perform all obligations
thereunder, and,

as to such parties, we have also assumed the due authorization by all requisite
action, the due execution and delivery of such documents and the validity and
binding effect and enforceability thereof.

        Based on the foregoing, we are of the opinion that, upon effectiveness
of the Registration Statement and the approval of the issuance of the Merger
Shares by the AFC shareholders, the issuance of the Merger Shares in accordance
with the terms of the Merger Agreement will have been duly authorized and, when
the Merger Shares are issued in accordance with the terms of the Merger
Agreement and the Registration Statement, the Merger Shares will be validly
issued, fully paid and non-assessable.

        In rendering the opinions set forth above, we have not passed upon and
do not purport to pass upon the application of "doing business" or securities
or "blue-sky" laws of any jurisdiction (except federal securities laws).

        This opinion is given solely for the benefit of AFC and GNYSB and the
shareholders of GNYSB who exchange shares of GNYSB common stock for the Merger
Shares pursuant to the Registration Statement, and may not be relied upon by
any other person or entity, nor quoted in whole or in part, or otherwise
referred to in any document without our express written consent.

        We consent to the filing of this opinion as an Exhibit to the
Registration Statement and to the reference to our firm under the heading
"LEGAL MATTERS" in the Joint Proxy Statement-Prospectus that is part of such
Registration Statement.

                                                Very truly yours,

                   Re:  Merger of The Greater New York Savings Bank
                        into Astoria Federal Savings and Loan Association


Dear Sirs:

              You have requested our opinion regarding certain federal income
tax consequences of the merger (the "Merger") of The Greater New York Savings
Bank ("GNYSB"), a New York chartered stock savings bank, into Astoria Federal
Savings and Loan Association, ("Astoria Federal"), a federally chartered savings
bank and wholly-owned subsidiary of Astoria Financial Corporation ("AFC"), a
Delaware corporation. The Merger will be effected pursuant to the Agreement and
Plan of Merger dated as of the 29th day of March, 1997 by and among AFC, Astoria
Federal and GNYSB (the "Merger Agreement"). The Merger and related transactions
are described in the Merger Agreement and in the Joint Proxy
Statement-Prospectus (the "Proxy Statement") included in AFC's Registration
Statement on Form S-4 filed with the Securities and Exchange Commission in
connection with the Merger (the "Registration Statement"). All capitalized terms
used but not defined in this letter shall have the meanings set forth in the
Merger Agreement or in the Proxy Statement.

              In connection with the opinions expressed below, we have examined
and relied on originals, or copies certified or otherwise identified to our
satisfaction, of the Merger Agreement and of such corporate records of Astoria
Federal, AFC and GNYSB as we have deemed appropriate. We have also relied,
without independent verification, upon the          , 1997 letters of Astoria 
Federal, AFC and GNYSB to Thacher Proffitt & Wood containing certain tax 
representations. We have assumed that the parties will act, and that the Merger
will be effected, in accordance with the Merger Agreement, and that the 
representations made by Astoria Federal, AFC and GNYSB in the foregoing letters
are true, correct and complete. In addition, we have made such investigations 
of law as we have deemed appropriate to form a basis for the opinions 
expressed below.

         Based on and subject to the foregoing, it is our opinion that, for
Federal income tax purposes, under current law:

                  (1) The Merger will be treated as a reorganization within the
         meaning of Section 368(a) of the Code;

                  (2) No gain or loss will be recognized by Astoria Federal, AFC
         or GNYSB as a result of the Merger;

                  (3) Except to the extent of any cash received in lieu of a
         fractional share interest in GNYSB Common Stock or of any Cash
         Consideration received, no gain or loss will be recognized by holders
         of GNYSB Common Stock who exchange their shares of GNYSB Common Stock
         for shares of AFC Common Stock pursuant to the Merger;

                  (4) The tax basis of the shares of AFC Common Stock received
         by each holder of GNYSB Common Stock who exchanges shares of GNYSB
         Common Stock for shares of AFC Common stock in the Merger will be the
         same as the tax basis of the shares of GNYSB Common Stock surrendered
         pursuant to the Merger, reduced by any amount allocable to a fractional
         share interest of GNYSB Common Stock for which cash is received and by
         the amount of any Cash Consideration received, and increased by any
         gain recognized on such exchange;

                  (5) The holding period of the shares of AFC Common Stock
         received by each holder of GNYSB Common Stock in the Merger will
         include the holding period of the shares of GNYSB Common Stock
         exchanged therefor, provided that such stockholder holds such shares of
         GNYSB Common Stock as a capital asset at the Effective Time;

                  (6) No gain or loss will be recognized by the holders of GNYSB
         Series B Preferred Stock who exchange their shares of GNYSB Series B
         Preferred Stock solely for shares of AFC Series B Preferred Stock
         pursuant to the Merger;

                  (7) The tax basis of the shares of AFC Series B Preferred
         Stock received by each GNYSB stockholder who exchanges GNYSB Series B
         Preferred Stock solely for shares of AFC Series B Preferred Stock in
         the Merger will be the same as the tax basis of the GNYSB Series B
         Preferred Stock surrendered pursuant to the Merger; and

                  (8) The holding period of the shares of AFC Series B Preferred
         Stock received by each holder of GNYSB Series B Preferred Stock in the
         Merger will include the holding period of the shares of GNYSB Series B
         Preferred Stock exchanged therefor, provided that such stockholder
         holds such GNYSB Series B Preferred Stock as a capital asset at the
         Effective Time.

         Except as set forth above, we express no opinion to any party as to the
tax consequences, whether federal, state, local or foreign, of the Merger or of
any transaction related thereto or contemplated by the Merger Agreement. This
opinion is given solely for the benefit of GNYSB and its

Dear Sirs:

            We have acted as tax counsel to The Greater New York Savings Bank, a
New York State-chartered stock savings bank ("GNYSB") in connection with the
merger (the "Merger") of GNYSB with and into Astoria Federal Savings and Loan
Association, a federally chartered savings and loan association (the
"Association") pursuant to the Agreement and Plan of Merger, dated as of the
29th day of March, 1997 (the "Merger Agreement"), by and between Astoria
Financial Corporation, a Delaware Corporation ("AFC"), the Association, a wholly
owned subsidiary of AFC, and GNYSB. Unless otherwise indicated, capitalized
terms used herein have the meanings given to such terms in the Merger Agreement.

            In connection with this opinion, we have assumed with your consent
that (1) the Merger will be effected in accordance with the Merger Agreement and
will qualify as a merger under New York Banking Law [Sections 600, 601 and 602],
and (2) the statements set forth in letters to us from GNYSB and AFC dated
______, 1997, respectively, were true and correct when made and will be true and
correct as of the Effective Time and as to statements qualified by the best
<PAGE>   2

knowledge of the management of GNYSB or AFC, will be consistent with the
underlying facts as of the Effective Time.

            Based upon and subject to the foregoing, and our consideration of
such other matters of fact and law as we have considered necessary or
appropriate for purposes of rendering this opinion, it is our opinion, under
presently applicable United States Federal income tax law, that:

            1. The Merger will constitute a reorganization within the meaning of
Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code").

            2. No gain or loss will be recognized by AFC, the Association or
GNYSB as a result of the Merger.

            3. Except to the extent of any cash received in lieu of fractional
share interest in AFC Common Stock or of any Cash Consideration received, no
gain or loss will be recognized by stockholders of GNYSB who exchange their
GNYSB Common Stock for AFC Common Stock pursuant to the Merger.

            4. The tax basis of the shares of AFC Common Stock received by GNYSB
stockholders who exchange their GNYSB Common Stock for shares of Parent Common
Stock in the Merger will be the same as the tax basis of the shares of GNYSB
Common Stock surrendered pursuant to the Merger, reduced by any amount of tax
basis allocable to a fractional share interest for which cash is received and by
the amount of any Cash Consideration received and increased by any gain
recognized in the exchange.

            5. The holding period of the shares of AFC Common Stock received by
each holder of GNYSB Common Stock in the Merger will include the holding period
of the shares of GNYSB Common Stock exchanged therefor, provided that such
<PAGE>   3
The Greater New York Savings Bank                                            -3-



stockholder held such GNYSB Common Stock as a capital asset on the date of the
Merger.

            6. No gain or loss will be recognized by stockholders of GNYSB who
exchange their shares of GNYSB Series B Preferred Stock solely for AFC Series B
Preferred Stock pursuant to the Merger.

            7. The tax basis of the shares of AFC Series B Preferred Stock
received by GNYSB stockholders who exchange their GNYSB Series B Preferred Stock
for shares of AFC Series B Preferred Stock in the Merger will be the same as the
tax basis of the shares of GNYSB Series B Preferred Stock surrendered pursuant
to the Merger.

            8. The holding period of the shares of AFC Series B Preferred Stock
received by each holder of GNYSB Series B Preferred Stock in the Merger will
include the holding period of the shares of GNYSB Series B Preferred Stock
exchanged therefor, provided that such stockholder held such GNYSB Series B
Preferred Stock as a capital asset on the date of the Merger.

            We express no opinion as to the effect of the Merger on GNYSB, AFC,
the Association or stockholders of GNYSB in respect of (i) any asset as to which
unrealized gain is required to be recognized for U.S. Federal income tax
purposes at the end of each taxable year under a mark-to-market system, (ii) any
obligation of AFC (or any of its subsidiaries) or GNYSB (or any of its
subsidiaries) that becomes an "intercompany obligation" within the meaning of
Treasury Regulation Section 1.1502-13(g)(2)(ii) as a result of the Merger, (iii)
the character of income, if any, recognized by
<PAGE>   4
The Greater New York Savings Bank                                            -4-


shareholders on the redemption of Rights or (iv) the possibility that the
payment by AFC or the Association of state or local transfer taxes, if any,
arising in connection with the Merger will be treated as a payment of Cash
Consideration to GNYSB stockholders.

            We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement on Form S-4 of AFC filed in connection with the Merger
and to the references to us under the headings "SUMMARY -- Certain Federal
Income Tax Considerations" and "THE MERGER -- Certain Federal Income Tax
Considerations" in the Joint Proxy Statement-Prospectus of GNYSB and AFC. In
giving such consent, we do not thereby admit that we are in the category of
persons whose consent is required under Section of the Securities Act of 1933.

                         Pursuant to Section 151 of the
                General Corporation Law of the State of Delaware


         We, GEORGE L. ENGELKE, JR. and WILLIAM K. SHEERIN, being the Chairman
of the Board, President, and Chief Executive Officer and the Senior Vice
President and Corporate Secretary, respectively, of ASTORIA FINANCIAL
CORPORATION (the "Corporation"), a corporation organized and existing under the
General Corporation Law of the State of Delaware (the "DGCL"), in accordance
with the provisions of Section 151 thereof, DO HEREBY CERTIFY that, pursuant to
the authority conferred upon the board of directors of the Corporation (the
"Board of Directors") by the certificate of incorporation of the Corporation, as
amended (the "Certificate of Incorporation"), the Board of Directors authorized
the series of preferred stock hereinafter provided for and established the
powers thereof and has adopted the following resolution creating a series of two
million (2,000,000) shares of preferred stock, par value $1.00 per share,
designated as 12% Noncumulative Perpetual Preferred Stock, Series B:

                  RESOLVED that, pursuant to the authority vested in the Board
         of Directors in accordance with the provisions of its Certificate of
         Incorporation, a series of preferred stock of the Corporation be, and
         it hereby is, created, and that the designation and amount thereof and
         the powers, preferences and relative, participating, optional or other
         special rights of the shares of such series, and the qualifications,
         limitations or restrictions thereof are as follows:

         SECTION 1.  DESIGNATION AND AMOUNT.

         (A) The shares of this series of preferred stock shall be designated as
12% Noncumulative Perpetual Preferred Stock, Series B (the "Series B Preferred
Stock") and the number of shares constituting such series shall be two million
(2,000,000) shares. Shares of the Series B Preferred Stock shall have a par
value of $1.00 per share.

         (B) The number of authorized shares of the Series B Preferred Stock may
be reduced from time to time, but not below the number of shares of Series B
Preferred Stock then outstanding, by further resolution duly adopted by the
Board of Directors. The number of authorized shares of the Series B Preferred
Stock shall not be increased. Fractional shares of the Series B Preferred Stock,
rounded to the nearest one-hundredth of a whole number, may be issued.



<PAGE>   2
    SECTION 2.   RANKING; ATTRIBUTABLE CAPITAL AND ADEQUACY OF SURPLUS.

    (A) With respect to dividend rights, the Series B Preferred Stock shall rank
prior to common stock of all classes of the Corporation (collectively, the
"Common Stock") and to all other classes and series of equity securities of the
Corporation now or hereafter authorized, issued or outstanding other than Parity
Dividend Stock and Senior Dividend Stock. Parity Dividend Stock shall mean any
class or series of equity securities of the Corporation expressly designated as
ranking, with respect to dividend rights, on a parity with the Series B
Preferred Stock, and Senior Dividend Stock shall mean any class or series of
equity securities of the Corporation expressly designated as ranking, with
respect to dividend rights, as senior to the Series B Preferred Stock.

    (B) With respect to rights upon the voluntary or involuntary liquidation,
dissolution or winding up of the Corporation, the Series B Preferred Stock shall
rank prior to the Common Stock and to all other classes and series of equity
securities of the Corporation now or hereafter authorized, issued or outstanding
other than Parity Liquidation Stock and Senior Liquidation Stock. Parity
Liquidation Stock shall mean any class or series of equity securities of the
Corporation expressly designated as ranking, with respect to rights upon the
voluntary or involuntary liquidation, dissolution or winding up of the
Corporation, on a parity with the Series B Preferred Stock, and Senior
Liquidation Stock shall mean any class or series of equity securities of the
Corporation expressly designated as ranking, with respect to rights upon the
voluntary or involuntary liquidation, dissolution or winding up of the
Corporation, as senior to the Series B Preferred Stock.

    (C) To the extent not expressly prohibited by the Certificate of
Incorporation, the Series B Preferred Stock shall be subject to the creation of
Parity Dividend Stock and Parity Liquidation Stock (collectively, "Parity
Stock") and of the Common Stock and all other classes and series of equity
securities of the Corporation ranking junior to the Series B Preferred Stock
with respect to dividend rights ("Junior Dividend Stock") or rights upon the
voluntary or involuntary liquidation, dissolution or winding up of the
Corporation ("Junior Liquidation Stock" and, collectively with Junior Dividend
Stock, "Junior Stock"). Shares of the Corporation's Series A Junior
Participating Preferred Stock are hereby designated as Junior Dividend Stock and
as Junior Liquidation Stock. No shares of Senior Dividend Stock or Senior
Liquidation Stock shall be created without the consent of the holders of Series
B Preferred Stock as provided in Section 6(C) hereof.

    (D) The capital of the Corporation allocable to the Series B Preferred Stock
for purposes of the DGCL shall be $1.00 per share. In addition to any vote of
stockholders required by law, the vote of the holders of a majority of the
outstanding shares of the Series B Preferred Stock shall be required to increase
the par value of the Common Stock or otherwise increase the capital of the
Corporation allocable to the Common Stock for the purpose of the DGCL if, as a
result thereof, the surplus of the Corporation for purposes of the DGCL would be
less than the amount of dividends that would accrue on the then-outstanding
shares of the Series B Preferred Stock during the following three years.

    SECTION 3.   NONCUMULATIVE DIVIDENDS; PRIORITY.

    (A) (i) Subject to the restrictions and limitations on declaration and
payment of dividends specified in Section 11 hereof, the holders of record of
shares of the Series B Preferred Stock shall be entitled to receive, when, as
and if declared by the Board of Directors, out of funds legally available
therefor, noncumulative cash dividends at an annual rate of 12% of the $25.00
liquidation preference per share ($3.00 per share per annum), and no more.
Dividends on the Series B Preferred Stock shall be declared and paid in cash
only. Such noncumulative cash dividends shall be declared and payable quarterly
in arrears in the amount set forth in Section 3(A) (iii) on January 15, April
15, July 15 and October 15 of each year or, if such day is not a Business Day
(as defined in Section 9 hereof), on the next Business Day (each such date, a
"Dividend Payment Date"). The first Dividend Payment Date shall be the first
such date to occur after the Effective Time as defined in the Agreement and Plan
of Merger, dated as of the 29th day of March, 1997, as amended by and among the
Corporation, Astoria Federal Savings and Loan Association and The Greater New
York Savings Bank. Each declared dividend shall be payable to holders of record
of the Series B Preferred Stock as they appear on the stock books of the
Corporation (or of any transfer agent for the Series B Preferred Stock) at the
close of business on such record dates, not more than fifty (50) calendar days
nor less than ten (10) calendar days preceding the Dividend Payment Date
therefor, as determined by the Board of Directors (each such date, a "Record
Date"). The initial period for which dividends shall be paid (the "Initial
Dividend Period") shall commence on the last "Dividend Period Commencement Date"
that occurred under the 12% Noncumulative Perpetual Preferred Stock, Series B,
of The Greater New York Saving Bank and shall end on and include the date next
preceding the first Dividend Period Commencement Date (as defined below) to
occur after the Effective Time. Thereafter, quarterly dividend periods (each, a
"Dividend Period") shall commence on and include March 1, June 1, September 1
and December 1 of each year (each such date, a "Dividend Period Commencement
Date") and shall end on and include the date next preceding the Dividend Period
Commencement Date of the following Dividend Period.

    (ii)  Dividends on the Series B Preferred Stock shall be noncumulative. If a
dividend on the Series B Preferred Stock with respect to any Dividend Period
(including the Initial Dividend Period) is not declared by the Board of
Directors, the Corporation shall have no obligation at any time to pay a
dividend on the Series B Preferred Stock with respect to such Dividend Period,
whether or not dividends are declared payable with respect to any future
Dividend Period. The holders of the Series B Preferred Stock shall not be
entitled to any dividends in excess of the noncumulative dividends declared by
the Board of Directors, as set forth in this paragraph (A).

    (iii) The amount of dividends payable on each share of Series B Preferred
Stock for each full Dividend Period during which such share is outstanding shall
be $0.75. The amount of dividends payable for the Initial Dividend Period and
for any Dividend Period which is less than a full three (3) months shall be
computed on the basis of a 360-day year composed of twelve (12) 30-day months
and the actual number of days elapsed in the Initial Dividend Period or such
Dividend Period.

    (iv)  The Series B Preferred Stock shall not participate in dividends with
the Common Stock.



                                       -3-
<PAGE>   4
    (v)   The holders of the Series B Preferred Stock shall not be entitled to
any interest, or any sum of money in lieu of interest, in respect of any
dividend payment or payments on the Series B Preferred Stock declared by the
Board of Directors which may be unpaid.

    (B)   (i) No full dividends shall be declared or paid or set apart for
payment on any Parity Dividend Stock for any Dividend Period unless full
dividends have been or contemporaneously are declared and paid (or declared and
a sum sufficient for the payment thereof set apart for such payment) on the
Series B Preferred Stock for such Dividend Period. When dividends are not paid
in full (or declared and a sum sufficient for such full payment is not so set
apart) for any Dividend Period on the Series B Preferred Stock and any other
Parity Dividend Stock, dividends declared on the Series B Preferred Stock and
other Parity Dividend Stock shall only be declared pro rata, such that the
amount of dividends declared per share on the Series B Preferred Stock and other
Parity Dividend Stock shall bear to each other the same ratio that, at the time
of such declaration, all accrued and payable but unpaid dividends for such
Dividend Period per share on shares of the Series B Preferred Stock (which shall
not include any accumulation in respect of unpaid dividends for prior Dividend
Periods) and other Parity Dividend Stock bear to each other.

    (ii)  The Corporation shall not (a) declare or (b) pay or set apart funds
for any dividends or other distributions (other than in Common Stock or other
Junior Stock) with respect to any Common Stock or other Junior Dividend Stock of
the Corporation, or (c) (except by conversion into or exchange for Junior Stock)
repurchase, redeem or otherwise acquire, or set apart funds for the repurchase,
redemption or other acquisition of, any Common Stock or other Junior Stock
through a sinking fund or otherwise, unless the Corporation shall have, in the
case of clause (a) declared, or in the case of clauses (b) or (c) paid or set
apart funds for the payment of, full dividends on the Series B Preferred Stock
with respect to the same calendar quarter for which (x) the dividend or other
distribution is being declared or paid, as the case may be, on the Common Stock
or other Junior Stock or (y) the Common Stock or other Junior Stock is being
repurchased, redeemed or otherwise acquired.

    (C)   Any reference to "dividends" or "distributions" in this Section 3
shall not be deemed to include any distribution made in connection with any
voluntary or involuntary liquidation, dissolution or winding up of the
Corporation.

    SECTION 4.   REDEMPTION AT THE OPTION OF THE CORPORATION.

    (A)   (i) The shares of the Series B Preferred Stock shall not be subject to
mandatory redemption, and shall not be redeemable by the Corporation prior to
October 1, 2003. On or after October 1, 2003, shares of the Series B Preferred
Stock may be redeemed by the Corporation, at its option, in whole or in part, at
any time or from time to time, upon notice as provided in paragraph (B) of this
Section 4, by resolution of the Board of Directors, at the redemption prices set
forth below in cash, plus, in each case, an amount in cash equal to all accrued
and unpaid dividends thereon (whether or not declared) from the Dividend Period
Commencement Date next

Preferred Stock to be redeemed at such holder's address as the same shall appear

the Redemption Date. Neither failure to mail such notice, nor any defect therein
or in the mailing thereof, to any particular holder shall affect the sufficiency
of the notice or the validity of the proceedings for redemption with respect to
the other holders. Any notice which was mailed in the manner herein provided
shall be conclusively presumed to have been duly given whether or not the holder
receives such notice.

    (ii)   On or after the Redemption Date, each holder of shares of the Series
B Preferred Stock to be redeemed shall present and surrender the certificate or
certificates for such shares to the Corporation at the place designated in the
notice given to such holder, and thereupon the redemption price of such shares
shall be paid to or on the order of the person whose name appears


                                       -5-
<PAGE>   6
on such certificate or certificates as the owner thereof, and each surrendered
certificate shall be cancelled. If fewer than all the shares represented by any
such certificate are redeemed, a new certificate representing the unredeemed
shares shall be issued to the holder of such shares.

    (iii)  If such notice of redemption shall have been so mailed, and if, on or
before the Redemption Date specified in such notice, all funds necessary for
such redemption shall have been set aside by the Corporation, separate and apart
from its other funds, in trust for the account of the holders of shares of the
Series B Preferred Stock to be redeemed (so as to be and continue to be
available therefor), then, on and after the Redemption Date, notwithstanding
that any certificates for shares of the Series B Preferred Stock so called for
redemption shall not have been surrendered for cancellation, the shares of the
Series B Preferred Stock so called for redemption shall be deemed to be no
longer outstanding and the holders of such shares shall cease to be stockholders
of the Corporation and shall have no voting or other rights with respect to such
shares, except for the right to receive out of the funds so set aside in trust
the amount payable on redemption thereof, without interest, upon surrender (and
endorsement or assignment for transfer, if required by the Corporation) of their
certificates.

    (iv)   In the event that holders of shares of the Series B Preferred Stock
that have been redeemed shall not, within two (2) years (or any longer period
required by law) after the Redemption Date, claim any amount deposited in trust
with a bank or trust company for the redemption of such shares, such bank or
trust company shall, upon demand by the Corporation and if permitted by
applicable law, pay over to the Corporation any such unclaimed amount so
deposited with it, and shall thereupon be relieved of all responsibility in
respect thereof, and thereafter the holders of such shares shall, subject to
applicable escheat laws, look only to the Corporation for payment of the
redemption price thereof, but without interest from the Redemption Date. Any
interest accrued on funds deposited in trust as aforesaid shall be paid to the
Corporation from time to time.

    (C)    If fewer than all the outstanding shares of the Series B Preferred
Stock are to be redeemed, the shares to be redeemed shall be selected pro rata
or by lot or by such other method as the Board of Directors, in its sole
discretion, determines to be equitable.

    (D)    Shares of the Series B Preferred Stock redeemed, purchased or
otherwise acquired for value by the Corporation shall, after such redemption,
purchase or acquisition, be retired and cancelled in accordance with the
provisions of the DGCL. All such shares shall upon their cancellation become
authorized but unissued shares of preferred stock and may be reissued as part of
a new series of preferred stock to be created by resolution or resolutions of
the Board of Directors as permitted by law (other than as shares of the Series B
Preferred Stock).

    (E)    The Series B Preferred Stock shall not be subject to the operation of
any mandatory purchase, retirement or sinking fund.

    SECTION 5.   LIQUIDATION PREFERENCE.

    (A)  In the event of any voluntary or involuntary liquidation, dissolution
or winding up of the Corporation, the holders of shares of the Series B
Preferred Stock shall be entitled to receive for each share thereof, out of the
assets of the Corporation which are legally available for distribution to
stockholders under applicable law, or the proceeds thereof, before any payment
or distribution of such assets or proceeds shall be made to holders of shares of
the Common Stock or any other Junior Liquidation Stock, liquidating
distributions in the amount of $25.00 per share, plus an amount per share equal
to all accrued, undeclared and unpaid dividends thereon from the Dividend Period
Commencement Date next preceding the date fixed for such liquidation,
dissolution or winding up (the "Liquidation Date") to, but excluding, the
Liquidation Date (without accumulation of unpaid dividends for prior Dividend
Periods), and no more; provided, however, that the holders of shares of the
Series B Preferred Stock and any Parity Liquidation Stock shall be entitled to
such liquidating distributions only after payment in full of liquidating
distributions to holders of shares of any Senior Liquidation Stock. If the
amounts available for distribution in respect of shares of the Series B
Preferred Stock and any Parity Liquidation Stock are not sufficient to satisfy
the full liquidation rights of all the outstanding shares thereof, the holders
of such outstanding shares of the Series B Preferred Stock and such Parity
Liquidation Stock shall share ratably in any such distribution of assets in
proportion to the full respective preferential amounts to which they are
entitled. After payment of the full amount of the liquidating distribution to
which they are entitled, the holders of shares of the Series B Preferred Stock
as such shall not be entitled to any further participation in any distribution
of assets by the Corporation. All distributions made in respect of the Series B
Preferred Stock in connection with such a liquidation, dissolution or winding up
of the Corporation shall be made pro rata to the holders of the Series B
Preferred Stock entitled thereto.

    (B)  Neither the merger or consolidation of the Corporation with or into any
other entity, nor the merger or consolidation of any other entity with or into
the Corporation, nor the sale, transfer or lease of all or any portion of the
assets of the Corporation, shall be deemed to be a liquidation, dissolution or
winding up of the affairs of the Corporation for purposes of this Section 5.

    (C)  Written notice of any voluntary or involuntary liquidation, dissolution
or winding up of the Corporation, stating the payment date or dates when, and
the place or places where, the amounts distributable to holders of the Series B
Preferred Stock in such circumstances shall be payable, shall be given by
first-class mail, postage prepaid, mailed not less than twenty (20) days prior
to any payment date stated therein, to each holder of record of the Series B
Preferred Stock, at such holder's address as the same shall appear on the stock
books of the Corporation (or of any transfer agent for the Series B Preferred
Stock).

    SECTION 6. VOTING RIGHTS.

    (A)   Except as expressly provided in this Section 6, or as otherwise
required by applicable law or regulation, the holders of shares of the Series B
Preferred Stock shall have no voting rights.

    (B)   (i) The holders of shares of the Series B Preferred Stock shall be
entitled to exercise the voting rights provided for in this paragraph (B) of
Section 6 (the "Election Right") upon the occurrence of a "Voting Event." It
shall be a Voting Event if the Corporation shall have failed to make the payment
of full dividends on the Series B Preferred Stock (or the declaration of such
full dividends and the setting apart of a sum sufficient for payment thereof)
with respect to each of any six (6) Dividend Periods (including the Initial
Dividend Period), whether consecutive or not. A Voting Event shall be deemed to
have occurred as of the Dividend Payment Date of the Dividend Period that is the
sixth (6th) Dividend Period for which the payment of full dividends on the
Series B Preferred Stock has not been made (or declared and set apart for
payment).

    (ii)  Upon the occurrence of a Voting Event, the maximum authorized number
of directors of the Corporation, without further action, shall be increased by
two (2). The holders of shares of the Series B Preferred Stock and the holders
of any other class or series of Parity Stock as to which the payment of
dividends is in arrears and unpaid in an aggregate amount equal to or exceeding
the amount of dividends payable for six (6) quarterly dividend periods (or if
dividends are payable other than on a quarterly basis the number of dividend
periods, whether or not consecutive, containing in the aggregate not less than
five hundred forty (540) calendar days) and upon which by its terms the same
right to elect two (2) directors has been conferred and is exercisable ("Voting
Parity Stock"), shall have the exclusive right, voting together as a single
class, to elect the two (2) additional directors at the Corporation's next
annual meeting of stockholders or at a special meeting of stockholders as
provided below and to reelect two (2) directors at each subsequent annual
meeting of stockholders until the Election Right terminates as provided in
subsection (iv) of this paragraph (B). At any time when the Election Right shall
have so vested, the Corporation may, and upon the written request of the holders
of record of not less than 20% of the total number of shares of the Series B
Preferred Stock and such Voting Parity Stock then outstanding shall, call a
special meeting of the holders of such shares to fill such newly-created
directorships for the election of directors. In the case of such a written
request, such special meeting shall be held within ninety (90) days after the
delivery of such request and, in either case, at the place and upon the notice
provided by law and in the bylaws of the Corporation (the "Bylaws"), provided
that the Corporation shall not be required to call such a special meeting if
such request is received less than one hundred twenty (120) days before the date
fixed for the next succeeding annual meeting of stockholders of the Corporation,
at which meeting such newly-created directorships shall be filled by the holders
of such shares. If, prior to the end of the term of any director elected as
aforesaid, a vacancy in the office of such director shall occur by reason of
death, resignation, disability or disqualification, the remaining director
elected as aforesaid shall appoint a successor to hold office for the unexpired
term of such former director, and if both directors elected as aforesaid shall
cease to serve as directors before their terms shall


                                       -8-
<PAGE>   9
expire, the holders of the Series B Preferred Stock and any Voting Parity Stock
then outstanding may, at a meeting of such holders duly held, elect successors
to hold office for the unexpired terms of such directors whose places shall be
vacant. The election or appointment of any person as a director pursuant to this
Section 6 shall be subject to compliance with any requirement for regulatory
approval of (or non-objection to) such person's serving as a director.

    (iii)  The majority of the holders of the Series B Preferred Stock and any
Voting Parity Stock then outstanding, voting together as a single class, shall
have the right at any time to remove without cause and replace any directors
which such holders have elected or who have been appointed pursuant to this
Section 6.

    (iv)   The Election Right of the holders of the Series B Preferred Stock and
the term of the directors elected to the Board of Directors pursuant to a
particular exercise of such Election Right shall continue until full dividends
have been declared and paid for four (4) consecutive Dividend Periods following
the vesting of such Election Right, at which time such Election Right and the
term of such directors shall, without further action, terminate, subject to
revesting of the Election Right upon the occurrence of a subsequent Voting
Event; provided, however, that if, at the time of termination of the Election
Right of the holders of the Series B Preferred Stock, there shall be outstanding
any Voting Parity Stock having similar voting rights which remain in effect, the
term of any directors elected by the holders of the Series B Preferred Stock and
such Voting Parity Stock shall continue until such time as the voting right of
the holders of such Voting Parity Stock shall terminate by its terms. Upon such
termination the number of directors constituting the Board of Directors shall,
without further action, be reduced by two (2), subject always to increase of the
number of directors pursuant to the foregoing provisions in case of the
revesting of the Election Right upon the occurrence of a subsequent Voting
Event.

    (v)    The directors elected pursuant to this Section 6 shall not become
members of any of the three classes of directors otherwise required by Article
Sixth A. of the Certificate of Incorporation. If the Certificate of
Incorporation, the Bylaws and applicable law were construed to require
classification of such directors and as a result, or if for any other reason,
the holders of the shares of the Series B Preferred Stock and any Voting Parity
Stock then outstanding are not able to elect the specified number of directors
at the next annual meeting of stockholders in the manner described above, the
Corporation shall use its best efforts to take all actions necessary to permit
the full exercise of such voting rights (including, if necessary, taking action
to increase the authorized number of directors standing for election at such
next annual meeting of stockholders or seeking to amend, alter or change the
Certificate of Incorporation or Bylaws).

    (C)    (i) So long as any shares of the Series B Preferred Stock are
outstanding, the Corporation shall not, without the consent of the holders of at
least 66-2/3% of the outstanding shares of the Series B Preferred Stock, voting
together as a single class, (a) amend, alter or repeal or otherwise change any
provision of the Certificate of Incorporation or this Certificate of
Designations (including any such amendment, alteration, repeal or change
effected by any merger or consolidation in which the Corporation is the
surviving or resulting corporation) if such amendment, alteration, repeal or
change would materially and adversely affect the rights,


                                       -9-
<PAGE>   10
preferences, powers or privileges of the Series B Preferred Stock, or (b)
authorize, create or issue or increase the authorized or issued amount of any
class or series of Senior Dividend Stock or Senior Liquidation Stock or any
warrants, options or other rights convertible into or exchangeable for any class
or series of Senior Dividend Stock or Senior Liquidation Stock.

    (ii)   The creation or issuance of Parity Stock or Junior Stock, or the
distribution of assets upon a voluntary or involuntary liquidation, dissolution
or winding up of the Corporation, or a merger, consolidation, reorganization or
other business combination in which the Corporation is not the surviving or
resulting corporation, or an amendment which substitutes the surviving or
resulting corporation in a merger or consolidation for the Corporation or which
increases the number of shares of preferred stock which the Corporation is
authorized to issue, shall not be deemed to be a material and adverse change to
the rights, preferences, powers or privileges of the Series B Preferred Stock
requiring a vote of the holders of shares of the Series B Preferred Stock
pursuant to this paragraph (C).

    (iii)  No vote of the Series B Preferred Stock shall be required if the
Series B Preferred Stock is to be redeemed in whole on a Redemption Date
occurring on or prior to the date of occurrence of any event otherwise requiring
a class vote by the Series B Preferred Stock.

    (D)    Except as provided by law or regulation or the provisions of the
Certificate of Incorporation, the presence at a meeting, in person or by proxy,
of stockholders entitled to cast a majority of the shares of the Series B
Preferred Stock outstanding and entitled to vote on any matter shall constitute
a quorum of such stockholders; provided, however, if any matter shall require a
vote of holders of shares of the Series B Preferred Stock and any Voting Parity
Stock, voting together as a single class, the presence at a meeting, in person
or proxy, of stockholders entitled to cast a majority of the shares of the
Series B Preferred Stock and such Voting Parity Stock which is outstanding and
entitled to vote on any matter shall constitute a quorum of such stockholders.
In connection with any matter on which holders of the Series B Preferred Stock
are entitled to vote as one class or otherwise pursuant to law or regulation or
the provisions of the Certificate of Incorporation, each holder of the Series B
Preferred Stock shall be entitled to one vote for each share of the Series B
Preferred Stock held by such holder.

    SECTION 7.   NO CONVERSION, PREEMPTIVE OR SUBSCRIPTION RIGHTS.

    The holders of shares of the Series B Preferred Stock shall not have any
rights to convert such shares into shares of any other class or series of
capital stock or into any other securities of, or any interest in, the
Corporation. The Series B Preferred Stock is not entitled to any preemptive or
subscription rights with respect to any securities of the Corporation.

    SECTION 8.   NO OTHER RIGHTS.

    The shares of the Series B Preferred Stock shall not have any powers,
designations, preferences and relative, participating, optional and other
special rights except as set forth herein


                                      -10-
<PAGE>   11
or in any other provision of the Certificate of Incorporation or as otherwise
required by applicable law or regulation.

    SECTION 9.   BUSINESS DAY.

    For purposes hereof, the term "Business Day" shall mean any day other than a
Saturday, a Sunday or a day on which banking institutions in New York, New York
are obligated or authorized by law or executive order to be closed.

    SECTION 10.  ACTION BY COMMITTEE OF BOARD OF DIRECTORS.

    To the extent permitted by applicable law, any action specified herein as
being authorized or required to be taken by the Board of Directors may be taken
by a duly authorized committee thereof.

    SECTION 11.  COMPLIANCE WITH APPLICABLE LAW AND OTHER RESTRICTIONS.

    Declaration by the Board of Directors and payment by the Corporation of
dividends to the holders of the Series B Preferred Stock and the repurchase,
redemption or other acquisition by the Corporation of shares of Series B
Preferred Stock shall be subject in all respects to any restrictions and
limitations placed on dividends, repurchases, redemptions or other distributions
by the Corporation under (a) laws, rules, regulations and regulatory conditions
or limitations applicable to or regarding the Corporation from time to time and
(b) orders, judgments, injunctions or decrees issued by, or agreements with,
federal or state banking authorities with respect to the Corporation from time
to time in effect.

    SECTION 12.  MISCELLANEOUS.

    (A)  All notices referred to herein shall be in writing, and except as
otherwise provided all notices hereunder shall be deemed to have been given upon
the earlier of receipt thereof or three (3) Business Days after the mailing
thereof if sent by registered mail (unless first-class mail shall be
specifically permitted for such notice under the terms of this Certificate of
Designations) with postage prepaid, addressed: (i) if to the Corporation, to its
office at One Astoria Federal Plaza, Lake Success, New York 11042-1895
(Attention: Secretary) or to the transfer agent for the Series B Preferred
Stock, if any, or other agent of the Corporation designated as permitted

such holder, as the case may be, shall have designated by notice similarly
given.

    (B)  In the event that a holder of shares of the Series B Preferred Stock
shall not by written notice designate to whom payment upon redemption of shares
of the Series B Preferred Stock should be made or the address to which such
payment should be sent, the Corporation shall


                                      -11-
<PAGE>   12
be entitled to make such payment in the name of the holder of such Series B
Preferred Stock as shown on the records of the Corporation and to send such
payment to the address of such holder shown on the records of the Corporation.

    (C)  Unless otherwise provided herein or in the Certificate of
Incorporation, as amended, all payments in the form of dividends, distributions

Corporation, or otherwise made upon the shares of the Series B Preferred Stock
and any Parity Stock shall be made pro rata, so that amounts paid per share on
the Series B Preferred Stock and such Parity Stock shall in all cases bear to
each other the same ratio that the required dividends, distributions or
payments, as the case may be, then payable per share on the shares of the Series
B Preferred Stock and such Parity Stock bear to each other.

    (D)  The Corporation may appoint, and from time to time discharge and
change, a transfer agent and registrar for the Series B Preferred Stock. Upon
